Rhea-AI Filing Summary

Air Industries Group plans to merge its subsidiary Merger Sub into Tenax Aerospace Acquisition, LLC, making Tenax a wholly owned subsidiary, and is registering stock on Form S-4 to issue or reserve 126,900,000 shares of common stock (adjusted to 25,380,000 shares after a proposed 1-for-5 reverse split) as merger consideration.

After closing, existing AIR holders are expected to own about 4% of the combined company on a fully diluted basis, while Tenax members and warrantholders will own about 96%, following an increase in authorized common shares from 20,000,000 to 200,000,000 and governance changes that enable written consents while the NTC Group and affiliates hold majority voting power.

Legacy AIR stockholders will keep their shares and receive non-transferable Redemption Rights, allowing a one-time cash redemption at 107.3% of the Debt Adjusted AIR Share Price of $3.05 per share (or $15.25 post-split) if the stock trades below that level around the first anniversary of closing; completion depends on stockholder approvals and regulatory clearances.

Positive

  • None.

Negative

  • Substantial dilution and control shift: post-merger, current AIR stockholders are expected to hold only 4% of the fully diluted common stock, with Tenax holders owning about 96%, and AIR becoming a "controlled company" under NYSE American rules.

Filing Explained

The July 22 filing is preliminary; no merger shares issue until S-4 effectiveness and stockholder approvals, while existing holders face the proposed dilution.

The July 22, 2026 Form S-4 is a preliminary registration statement and proxy statement/prospectus: it is not an offer to sell, and the securities may not be issued until the registration statement becomes effective.

At this stage, the filing changes the transaction process rather than ownership: if the S-4 becomes effective and the required votes are obtained, the proposed merger would proceed with the previously disclosed issuance or reservation of merger shares and dilution of existing AIR holders.

The S-4 combines securities registration with proxy solicitation and says the registration requirement was added to help satisfy the NYSE American listing requirement for the combined company; registration itself does not mean the shares have been issued or sold.

The filing qualifies its cited fairness opinion: Kipps said an unadjusted redemption price of $4.18 per share was fair as of February 17, 2026, but the filing expressly says the actual redemption price will be materially lower and identifies the Debt Adjusted AIR Share Price as $3.05, subject to the agreement.

Stockholders are not voting separately to approve the merger agreement itself. The special meeting will consider the stock issuance, authorized-shares and written-consent proposals, with the written-consent proposal requiring at least a majority of outstanding voting power; abstentions and broker non-votes have the same effect as votes against it.

The filing says the parties currently expect completion in September 2026, but the meeting date remains unspecified and completion still depends on the stated conditions, including S-4 effectiveness, stockholder approvals, listing approval and regulatory clearances.

Merger consideration shares (pre-split) 126,900,000 shares AIR common stock to be issued or reserved as consideration for Tenax
Merger consideration shares (post-split) 25,380,000 shares Amount after 1-for-5 reverse stock split and charter amendment
Post-merger legacy AIR ownership 4% of outstanding common stock Expected fully diluted ownership by pre-merger AIR stockholders
Post-merger Tenax ownership 96% of outstanding common stock Expected fully diluted ownership by Tenax members and warrantholders
Authorized shares increase 20,000,000 to 200,000,000 Proposed increase in authorized AIR common stock
Debt Adjusted AIR Share Price $3.05 per share Base price for Redemption Rights, $15.25 after reverse split
Termination / reverse termination fee $1.25 million Payable by AIR or Tenax if the merger agreement ends in specified cases
Redemption premium 107.3% Cash redemption price multiple of Debt Adjusted AIR Share Price
Redemption Rights financial
"a right to cause AIR to redeem shares of AIR common stock that such AIR stockholders then own"
Redemption rights are contractual provisions that allow a holder of a security—such as preferred shares, bonds, or certain fund units—to require the issuer to buy back the security under specified conditions, often at a set price or by a defined formula. For investors they act like a return policy that offers a forced exit or downside protection, affecting a security’s value, liquidity and the issuer’s cash planning.
reverse stock split financial
"reverse stock split, pursuant to NRS 78.207, of the issued and outstanding shares of AIR common stock"
A reverse stock split reduces a company's number of outstanding shares while raising the price per share proportionally, so the total value of each investor's holding is unchanged; a 1-for-10 split turns 100 shares worth $1 each into 10 shares worth $10 each. Companies often do this to regain compliance with an exchange's minimum price rule or to attract investors who avoid very low-priced stocks.
controlled company regulatory
"Following the consummation of the merger, AIR will be a “controlled company” for purposes of Section 801(a)"
A controlled company is a publicly traded firm where one shareholder or a small group holds enough voting power to determine board members and major strategic choices. For investors this matters because control can speed decision-making and protect long-term plans, but it also raises the risk that majority owners will favor their own interests over minority shareholders, reducing outside oversight—like a family-owned restaurant that sold shares but the family still calls the shots.
Smaller Reporting Company regulatory
"AIR is expected to qualify as a “Smaller Reporting Company” for purposes of Section 801(h)"
A smaller reporting company is a publicly traded firm that meets regulatory size tests allowing it to provide abbreviated financial disclosures and compliance filings compared with larger companies. For investors, that means financial statements and notes may be less detailed, which can make it harder to compare performance or spot risks—think of reading a short summary instead of a full report when deciding whether to buy or hold a stock.
Run-Rate EBITDA financial
"“Run-Rate EBITDA” refers to a forward-looking metric that forecasts EBITDA over the next twelve months"
An annualized estimate of EBITDA (earnings before interest, taxes, depreciation and amortization) based on a company’s most recent results, projecting what that profit measure would be over a full year if current conditions continue. Investors use run-rate EBITDA to quickly gauge ongoing cash-generating ability and to compare performance across companies; it’s like looking at a car’s current speed to guess how long a trip will take, but it can miss one-time events or changing conditions.
HSR Act regulatory
"expiration or termination of the applicable waiting periods under the HSR Act"
The HSR Act (Hart‑Scott‑Rodino Antitrust Improvements Act) requires companies in the United States to notify federal regulators and observe a waiting period before completing certain large mergers or acquisitions so authorities can check for anti-competitive effects. For investors it matters because the review can delay or block deals, force changes such as selling assets, and alter the expected value or timing of a transaction—like needing a permit before finalizing a major home renovation.

FAQ

What transaction is Air Industries Group (AIRI) proposing with Tenax?

Air Industries Group plans to merge its Merger Sub into Tenax, making Tenax a wholly owned subsidiary. AIR will issue or reserve 126,900,000 shares of common stock (adjusted to 25,380,000 post-split) as stock consideration to Tenax members and warrantholders.

How will the Tenax merger affect existing AIRI stockholders’ ownership?

After the merger, legacy Air Industries stockholders are expected to hold about 4% of the combined company on a fully diluted basis. Tenax members and warrantholders will collectively own about 96%, resulting in significant dilution and a change of control at AIR.

What are the Redemption Rights AIRI stockholders will receive?

Before closing, AIR will grant stockholders non-transferable Redemption Rights. These allow a one-time cash redemption at 107.3% of the $3.05 Debt Adjusted AIR Share Price (or $15.25 post-split) if the 20-day VWAP before the first anniversary is below that level.

What stockholder proposals must Air Industries Group (AIRI) approve for the merger?

Stockholders must approve: issuing AIR common stock as merger consideration, increasing authorized common shares from 20,000,000 to 200,000,000, and permitting written consents while specified holders control a majority, plus advisory compensation and potential adjournment proposals.

How will governance at Air Industries Group (AIRI) change after the Tenax merger?

Post-merger, AIR’s board will expand to at least eight directors, primarily designated by Tenax. With Tenax-related holders owning over 50% of voting power, AIR will qualify as a controlled company under NYSE American rules and may use related governance exemptions.

When is the Air Industries Group (AIRI) and Tenax merger expected to close?

Subject to stockholder approvals, effectiveness of the S-4, NYSE American listing of new shares, and required antitrust clearances, the companies currently expect closing in September 2026. Timing could change if conditions are delayed or not satisfied.

What happens if the Air Industries Group (AIRI)–Tenax merger is not completed?

If the merger fails, AIR and Tenax remain separate, Tenax members receive no AIR shares and AIR stockholders receive no Redemption Rights. In certain termination scenarios, either AIR or Tenax may owe the other a $1.25 million termination or reverse termination fee.

DATED JULY 22, 2026

LETTER FROM THE CHAIRMAN OF THE BOARD
AND
THE ACTING CHIEF EXECUTIVE OFFICER

YOUR VOTE IS VERY IMPORTANT

[•], 2026

To the stockholders of Air Industries Group:

We are pleased to invite you to attend a special meeting of stockholders of Air Industries Group, a Nevada corporation, referred to as AIR, to be held on [•], 2026, at [•] [A.M./P.M.], Eastern Time. The special meeting will be held in person at 1460 Fifth Avenue, Bay Shore, New York 11706. Stockholders attending in person may vote by ballot at the meeting. Stockholders not attending the special meeting in person may cast their vote by submitting proxies by Internet, by telephone or by mail according to the instructions provided in this proxy statement/prospectus.

As previously announced, AIR, Tenax Aerospace Acquisition, LLC, a Delaware limited liability company, referred to as Tenax, and Transitory Air Sub LLC, a Delaware limited liability company and a wholly owned subsidiary of AIR, referred to as Merger Sub, have entered into an Amended and Restated Agreement and Plan of Merger, dated as of July 2, 2026, referred to as the merger agreement. The merger agreement amended and restated that certain Agreement and Plan of Merger, dated as of February 16, 2026, by and among Tenax, AIR and Merger Sub (as amended by Amendment No. 1 to the Agreement and Plan of Merger, dated as of June 8, 2026), referred to as the original merger agreement. Pursuant to the terms of the merger agreement, Merger Sub will be merged with and into Tenax, with Tenax surviving the merger as a wholly owned subsidiary of AIR.

Tenax is an aerospace and defense supplier providing special mission aircraft and related aviation equipment and services to the U.S. and Canadian governments and other customers, focusing on enduring special mission aviation programs critical to national security and the public interest, including aerial firefighting, airborne ISR, airborne engagement simulation and airborne sensor testing and training.

At the effective time of the merger, AIR will issue or reserve for issuance, as applicable, 126,900,000 shares (which number will be adjusted to 25,380,000 shares after giving effect to the proposed amendment to the articles of incorporation of AIR contemplated by the authorized shares proposal and the subsequent reverse stock split of AIR’s common stock, each as described in this proxy statement/prospectus) of its common stock, par value $0.001 per share, referred to as AIR common stock, to the holders of membership interests of Tenax, referred to as the Tenax Members, and the holders of warrants of Tenax, referred to as the Tenax Warrantholders, as merger consideration. The portion of the merger consideration allocable to the Tenax Members will be issued at the effective time, and the portion of the merger consideration allocable to the Tenax Warrantholders will be reserved for issuance upon the exercise of their warrants, as further described herein.

AIR will survive following the merger and will remain a publicly traded corporation listed on the NYSE American under the symbol “AIRI”, referred to as the combined company. As a result of the merger, holders of our common stock as of immediately prior to the effective time are expected to collectively own approximately 4% of the outstanding shares of the common stock of the combined company, on a fully diluted basis, and the Tenax Members and Tenax Warrantholders as of immediately prior to the effective time are expected to collectively own approximately 96% of the outstanding shares of the common stock of the combined company, on a fully diluted basis.

In connection with the merger, AIR’s articles of incorporation will be amended to (a) increase the number of authorized shares of AIR common stock from 20,000,000 to 200,000,000 and (b) authorize stockholder action by written consent in lieu of a stockholder meeting at any time while NTC Group, Thomas Foley and Taran Bakker and their respective affiliates collectively beneficially own at least a majority of the voting power of the outstanding shares of AIR common stock, in each case as conditions to the closing of the merger.

At the special meeting, you will be asked to vote on:

1.      a proposal to approve the issuance of AIR common stock as merger consideration pursuant to the terms of the merger agreement, in compliance with Section 713(b) of the NYSE American Company Guide, resulting in a change of control of AIR, referred to as the stock issuance proposal;

 

Table of Contents

2.      a proposal to amend the articles of incorporation of AIR to increase the number of authorized shares of AIR common stock from 20,000,000 to 200,000,000, referred to as the authorized shares proposal;

3.      a proposal to amend the articles of incorporation of AIR to authorize stockholder action by written consent in lieu of a stockholder meeting at any time while NTC Group, Thomas Foley and Taran Bakker and their respective affiliates collectively beneficially own at least a majority of the voting power of the outstanding shares of AIR common stock, referred to as the written consent proposal;

4.      a proposal to approve an advisory resolution regarding the compensation that may be paid or become payable to AIR’s Named Executive Officers in connection with the merger, referred to as the transaction compensation proposal; and

5.      a proposal to adjourn the special meeting, if necessary or appropriate, including to solicit additional proxies, in the event that there are not sufficient votes at the time of the special meeting to approve items 1, 2 or 3 above, referred to as the adjournment proposal.

We are not asking our stockholders to approve the merger agreement or the merger.

Approval of the stock issuance proposal requires, in accordance with Section 713(b) of the NYSE American Company Guide, that the votes cast “FOR” the proposal exceed the votes cast “AGAINST” the proposal. Abstentions and broker non-votes will have no effect on the outcome of this vote.

Approval of the authorized shares proposal requires, pursuant to Section 1.8.1 of AIR’s bylaws and NRS 78.390(1)(a)(1), that the votes cast “FOR” the proposal exceed the votes cast “AGAINST” the proposal. Under Section 1.8.1 of AIR’s bylaws, “votes cast” means all votes cast in favor of and against the proposal and does not include abstentions or broker non-votes. Abstentions and broker non-votes will have no effect on the outcome of this vote.

Approval of the written consent proposal requires, pursuant to NRS 78.390(1)(a)(2), the affirmative vote of the holders of shares representing at least a majority of the voting power of the outstanding shares of AIR common stock entitled to vote thereon as of the record date for the special meeting. A failure to vote, a broker non-vote or an abstention will each have the same effect as a vote “AGAINST” this proposal.

Approval of the transaction compensation proposal is a non-binding, advisory vote. Stockholders are being asked to indicate their approval of the compensation that may be paid or become payable to AIR’s Named Executive Officers in connection with the merger. Because this vote is advisory and non-binding, it will not be determinative of whether such compensation is paid. The vote will be approved if the votes cast “FOR” exceed the votes cast “AGAINST.” Abstentions and broker non-votes will have no effect on the outcome of this vote.

Approval of the adjournment proposal requires that the votes cast “FOR” the proposal exceed the votes cast “AGAINST” the proposal. The approval of the adjournment proposal is not a condition to the consummation of the merger. Abstentions and broker non-votes will have no effect on the outcome of this vote.

The completion of the merger is conditioned on approval of the stock issuance proposal, the authorized shares proposal and the written consent proposal. Your vote is very important, regardless of the number of shares you own. Whether or not you plan to attend the special meeting, we hope you will vote as soon as possible.

Our board of directors has unanimously (a) determined that the merger agreement and the transactions contemplated thereby are fair to and in the best interests of AIR and its stockholders, (b) adopted and approved the merger agreement and the transactions contemplated by the merger agreement and (c) resolved to recommend that the stockholders of AIR approve the stock issuance proposal, the authorized shares proposal, the written consent proposal, the transaction compensation proposal and the adjournment proposal. ACCORDINGLY, OUR BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS THAT STOCKHOLDERS VOTE “FOR” THE STOCK ISSUANCE PROPOSAL, “FOR” THE AUTHORIZED SHARES PROPOSAL, “FOR” THE WRITTEN CONSENT PROPOSAL, “FOR” THE TRANSACTION COMPENSATION PROPOSAL AND “FOR” THE ADJOURNMENT PROPOSAL.

Our obligations to complete the merger are subject to the satisfaction or waiver of several conditions set forth in the merger agreement, a copy of which is included herein as Annex A. The proxy statement/prospectus provides you with detailed information about the proposed merger, the merger agreement and the transactions

This document, which forms part of the registration statement on Form S-4 filed with the SEC by AIR, constitutes a proxy statement of AIR under Section 14(a) of the Exchange Act. It also constitutes a notice of special meeting with respect to the special meeting at which AIR stockholders will be asked to consider and vote upon the stock issuance proposal, the authorized shares proposal, the written consent proposal, the transaction compensation proposal and the adjournment proposal.

On May 5, 2026, AIR filed a preliminary proxy statement with the SEC relating to the merger and containing certain of the information set forth in this proxy statement/prospectus. On July 2, 2026, AIR, Tenax and Merger Sub entered into the merger agreement, which amended and restated the original merger agreement to, among other things, require that AIR file a registration statement on Form S-4 with respect to the shares of AIR common stock to be issued to the Tenax Members as merger consideration. The purpose in including this requirement in the merger agreement was to facilitate the combined company’s satisfaction of the NYSE American listing requirement that the combined company have, as of the closing of the merger an aggregate market value of unrestricted publicly-held shares of at least $15 million. This proxy statement/prospectus sets forth additional information not contained in AIR’s previously filed preliminary proxy statement in order to reflect the terms of the amended and restated merger agreement and to satisfy the requirements of Form S-4.

QUESTIONS AND ANSWERS ABOUT THE MERGER AND THE SPECIAL MEETING

The following questions and answers are intended to briefly address some commonly asked questions regarding the merger, the merger agreement and the special meeting. These questions and answers may not address all questions that may be important to you as our stockholder. Please refer to the section entitled “Summary” beginning on page 1 of this proxy statement/prospectus and the more detailed information contained elsewhere in this proxy statement/prospectus, the annexes to this proxy statement/prospectus and the information incorporated by reference into this proxy statement/prospectus, which you should read carefully and in their entirety. You may obtain the information incorporated by reference into this proxy statement/prospectus without charge by following the instructions under the section entitled “Where You Can Find More Information” beginning on page 177 of this proxy statement/prospectus.

Q:     Why am I receiving this proxy statement/prospectus and proxy card?

A:     We have entered into the merger agreement pursuant to which Merger Sub will be merged with and into Tenax, with Tenax surviving the merger as a wholly owned subsidiary of AIR, which will remain a publicly traded corporation listed on NYSE American under the symbol “AIRI”.

Tenax is an aerospace and defense supplier providing special mission aircraft and related aviation equipment and services to the U.S. and Canadian governments and other customers. The company focuses on enduring special mission aviation programs critical to national security and the public interest, including aerial firefighting, airborne ISR, airborne engagement simulation and airborne sensor testing and training.

At the effective time of the merger, we will issue or reserve for issuance, as applicable, shares of AIR common stock to the Tenax Members and the Tenax Warrantholders as merger consideration. Pursuant to the merger agreement, the merger consideration will consist of 126,900,000 shares (which number will be adjusted to 25,380,000 shares after giving effect to the proposed amendment to the articles of incorporation of AIR contemplated by the authorized shares proposal and the subsequent reverse stock split, each as described in this proxy statement/prospectus) of AIR common stock to be issued to the Tenax Members and reserved for issuance to the Tenax Warrantholders upon the exercise of their warrants.

After the closing, the Tenax Members are expected to own approximately 96% of our outstanding AIR common stock, while our existing stockholders are expected to own approximately 4% of our outstanding AIR common stock.

Consummation of the merger is subject to approval by the AIR stockholders of the stock issuance proposal, the authorized shares proposal and the written consent proposal. We are holding the special meeting of our stockholders to ask our stockholders to consider and vote upon (i) the stock issuance proposal, (ii) the authorized shares proposal, (iii) the written consent proposal, (iv) the transaction compensation proposal and (v) the adjournment proposal.

This proxy statement/prospectus is being delivered to you by mail as our stockholder of record, as of the record date for the special meeting, in connection with the solicitation by the AIR Board of proxies to be voted at the special meeting. As a stockholder of record on the record date for the special meeting, you are invited to attend the special meeting and are entitled to and are requested to vote on the items of business described in this proxy statement/prospectus. This proxy statement/prospectus includes important information about the merger, the merger agreement, a copy of which is attached as Annex A to this proxy statement/prospectus, and the special meeting. You should read this information carefully and in its entirety before making any voting decisions.

Q:     How does this proxy statement/prospectus relate to the preliminary proxy statement previously filed by AIR with the SEC relating to the merger?

A:     On May 5, 2026, AIR filed a preliminary proxy statement with the SEC relating to the merger and containing certain of the information set forth in this proxy statement/prospectus. On July 2, 2026, AIR, Tenax and Merger Sub entered into the merger agreement, which amended and restated the original merger agreement to, among other things, require that AIR file a registration statement on Form S-4 with respect to the shares of AIR common stock to be issued to the Tenax Members as merger consideration. The purpose in including this requirement in the merger agreement was to facilitate the combined company’s satisfaction of the NYSE

iii

Table of Contents

American listing requirement that the combined company have an aggregate market value of unrestricted publicly-held shares of at least $15 million. This proxy statement/prospectus sets forth additional information not contained in AIR’s previously filed preliminary proxy statement in order to reflect the terms of the amended and restated merger agreement and to satisfy the requirements of Form S-4.

Q:     What items of business will be voted on at the special meeting?

A:     The items of business scheduled for the special meeting are:

Proposal 1:    The stock issuance proposal.

Proposal 2:    The authorized shares proposal.

Proposal 3:    The written consent proposal.

Proposal 4:    The transaction compensation proposal.

Proposal 5:    The adjournment proposal.

Q:     How does the AIR Board recommend that I vote?

A:     The AIR Board unanimously recommends a vote:

1.      FOR the stock issuance proposal;

2.      FOR the authorized shares proposal;

3.      FOR the written consent proposal;

4.      FOR the transaction compensation proposal; and

5.      FOR the adjournment proposal.

Q:     What is the voting requirement to approve each of the proposals?

A:     The following voting requirements will be in effect for each proposal described in this proxy statement/prospectus:

Proposal 1.    Approval of the stock issuance proposal requires that the number of shares voted “FOR” the stock issuance proposal must exceed the number of votes cast “AGAINST” the stock issuance proposal. Abstentions and broker non-votes will have no effect.

Proposal 2.    Approval of the authorized shares proposal requires that the number of shares voted “FOR” the authorized shares proposal must exceed the number of votes cast “AGAINST” the authorized shares proposal. Abstentions and broker non-votes will have no effect.

Proposal 3.    Approval of the written consent proposal requires the affirmative vote of the holders of shares representing at least a majority of the voting power of the outstanding shares of AIR common stock entitled to vote thereon as of the record date for the special meeting. A failure to vote, a broker non-vote or an abstention will each have the same effect as a vote “AGAINST” this proposal.

Proposal 4.    Approval of the transaction compensation proposal (on a non-binding, advisory basis) requires that the number of shares voted “FOR” the transaction compensation proposal must exceed the number of votes cast “AGAINST” the transaction compensation proposal. Abstentions and broker non-votes will have no effect.

Table of Contents

Q:     What will happen to my shares of AIR common stock, my AIR stock options and my AIR RSUs in connection with the merger?

A:     Upon completion of the merger, your shares of AIR common stock will remain outstanding and will not be converted into or exchanged for any other securities or cash. Your AIR stock options and your AIR RSUs will also remain outstanding and will continue on the same terms and conditions as were applicable immediately prior to the effective time. As a result of the issuance of the merger consideration to the Tenax Members, however, the overall ownership percentage of current AIR stockholders will be diluted upon completion of the merger.

Q:     Will I receive anything if the merger is completed?

A:     Prior to the closing, AIR will declare and issue, as a dividend to AIR stockholders as of the trading day immediately preceding the closing date, a right to cause AIR to redeem shares of AIR common stock that such AIR stockholders then own and continue to own on the first anniversary of the closing (a “Redemption Right”). The Redemption Rights will entitle the holders thereof to require AIR to purchase all or a portion of such AIR stockholder’s shares of AIR common stock for a redemption price, payable in cash, equal to 107.3% of the Debt Adjusted AIR Share Price, if the volume weighted average price of AIR common stock during the 20 trading days preceding the first anniversary of the closing is lower than 107.3% of the Debt Adjusted AIR Share Price. The Redemption Rights will not be transferable. See the section entitled “Other Related Agreements — Redemption Rights Agreement” beginning on page 12 of this proxy statement/prospectus.

Q:     What will the capital structure of AIR be after the consummation of the merger?

A:     As a result of the merger, the AIR stockholders as of immediately prior to the effective time will collectively own approximately 4% of the outstanding shares of AIR common stock, on a fully diluted basis, and the Tenax Members and Tenax Warrantholders will collectively own approximately 96% of the outstanding shares of AIR common stock, on a fully diluted basis, in each case subject to adjustment in accordance with the terms of the merger agreement. Following the merger, AIR will remain a publicly traded corporation, and shares of AIR common stock will continue to be listed on the NYSE American.

Q:     Who will serve on the AIR Board following the merger?

A:     In accordance with the merger agreement and concurrent with the merger, the AIR Board will be reconstituted such that it is composed of no fewer than eight directors, which shall consist only of (a) no fewer than six individuals designated by Tenax, namely Thomas Foley, Taran Bakker, Michael Ewald, Donald Fawcett, Bryan Fenton, DeWolfe Miller and John Young, and (b) two individuals to be mutually agreed upon by Tenax and AIR, namely [•] and [•], to hold office in accordance with the articles of incorporation and bylaws of AIR. See the section entitled “The Merger — Governance of AIR Following the Merger” beginning on page 62 of this proxy statement/prospectus.

Q:     Am I entitled to exercise dissenter’s rights in connection with the Transactions?

A:     No. Pursuant to the NRS, there are no dissenter’s rights available to the AIR stockholders in connection with the Transactions.

Q:     Do any of the AIR directors or executive officers have interests in the merger that may differ from or be in addition to my interests as an AIR stockholder?

A:     AIR’s directors and executive officers have certain interests in the merger that are different from, or in addition to, the interests of the AIR stockholders generally. The members of the AIR Board were aware of and considered these interests, among other matters, in evaluating, negotiating and approving the merger agreement and in determining to recommend that AIR stockholders approve the stock issuance proposal, the authorized shares proposal and the written consent proposal. See the section entitled “The Merger — Interests of AIR’s Directors and Executive Officers in the Merger” beginning on page 50 of this proxy statement/prospectus.

Q:     What are the material U.S. federal income tax consequences of the Transactions to the AIR stockholders?

Q1:   Will I be taxed upon receipt of my Redemption Rights?

A1.   The U.S. federal income tax consequences of your receipt of Redemption Rights is unclear. We intend to take the position that your receipt of the Redemption Rights constitutes an “open transaction”. Absent a change in law requiring otherwise after the date of the redemption rights agreement, we will not report the issuance of the Redemption Rights to you as a current distribution. This position may be challenged by the IRS, in which case you could be required to recognize taxable income in respect of your Redemption Rights without the corresponding receipt of cash. For a more complete description of the material U.S. federal income tax consequences of your receipt of Redemption Rights, including possible alternative tax treatments, see the section entitled “Material U.S. Federal Income Tax Consequences of the Transactions — Redemption Rights” beginning on page 90 of this proxy statement/prospectus.

Q2.   Will I be taxed as a result of the merger?

A2.   You will not recognize gain or loss for U.S. federal income tax purposes as a result of the merger and your holding period in your AIR common stock will remain unchanged.

Q:     When is the merger expected to be completed?

A:     Subject to the satisfaction or waiver of the closing conditions described under the section entitled “The Merger Agreement — Conditions to Completion of the Merger” beginning on page 80 of this proxy statement/prospectus, including the approval of the stock issuance proposal, the authorized shares proposal and the written consent proposal by our stockholders at the special meeting, we and Tenax currently expect that the merger will be completed in September 2026. However, it is possible that factors outside the control of both companies could result in the merger being completed at a different time or not at all.

Q:     Are there any risks that I should consider in deciding whether to vote for the stock issuance proposal, the authorized shares proposal and the written consent proposal?

A:     Yes. You should read and carefully consider the risks described in the section entitled “Risk Factors” beginning on page 16 of this proxy statement/prospectus.

Q:     What are the conditions to the completion of the merger?

A:     In addition to approval by our stockholders of the stock issuance proposal, the authorized shares proposal and the written consent proposal as described above, completion of the merger is subject to the satisfaction or waiver of a number of other conditions, including, among others, the effectiveness of the registration statement on Form S-4 of which this proxy statement/prospectus forms a part, approval for the listing of the AIR common stock to be issued as merger consideration on the NYSE American, receipt of certain required regulatory approvals, the accuracy of representations and warranties in the merger agreement (subject to certain materiality exceptions, other customary exceptions and customary cure rights), the absence of a material adverse effect on Tenax or AIR and Tenax’s and AIR’s performance in all material respects of their respective obligations under the merger agreement. For a more complete summary of the conditions that must be satisfied or waived prior to completion of the merger, see the section entitled “The Merger Agreement — Conditions to Completion of the Merger” beginning on page 80 of this proxy statement/prospectus.

Q:     Is consummation of the merger contingent upon any future approval by the Tenax Members?

A:     No. Concurrently with entering into the merger agreement, Tenax has obtained all approvals and consents of the Tenax Members necessary to effect the merger and the other Transactions. No further approvals by the Tenax Members are required to consummate the merger or the other Transactions other than those already obtained.

Table of Contents

Q:     What happens if the merger is not completed?

A:     If the stock issuance proposal, the authorized shares proposal and the written consent proposal are not approved by our stockholders or if the merger is not completed for any other reason, the AIR and Tenax businesses will not be combined. Accordingly, the Tenax Members will not receive shares of AIR common stock and the AIR stockholders will not be entitled to receive or exercise the Redemption Rights. If the merger agreement is terminated, under specified circumstances, we may be required to pay Tenax a termination fee of $1.25 million, and, if the merger agreement is terminated in certain other specified circumstances, Tenax may be required to pay us a reverse termination fee of $1.25 million. See the section entitled “The Merger Agreement — Termination of the Merger Agreement; Termination Fees” beginning on page 81 of this proxy statement/prospectus.

Q:     What happens if the transaction compensation proposal to approve, on a non-binding, advisory basis, the compensation that may be paid or become payable to AIR’s Named Executive Officers in connection with the merger is not approved?

A:     Approval, on a non-binding, advisory basis, of the compensation that may be paid or become payable to AIR’s Named Executive Officers in connection with the merger is not a condition to consummation of the merger. The vote on the transaction compensation proposal is a non-binding, advisory vote. If the merger is completed, AIR may be obligated to pay all or a portion of this compensation to its Named Executive Officers in connection with the merger or certain terminations of employment following the merger, even if AIR stockholders fail to approve the transaction compensation proposal.

Q:     Does my vote matter?

A:     Yes. The merger cannot be completed unless the stock issuance proposal, the authorized shares proposal and the written consent proposal are approved by our stockholders.

The effect of your vote depends on which proposal is being considered:

For the written consent proposal, if you fail to submit a proxy or vote in person at the special meeting, if your broker, bank or other nominee does not receive voting instructions from you, or if you vote to abstain, this will have the same effect as a vote “AGAINST” the proposal, because approval requires the affirmative vote of at least a majority of the voting power of all outstanding shares of AIR common stock entitled to vote as of the record date for the special meeting.

For the stock issuance proposal, the authorized shares proposal, the transaction compensation proposal and the adjournment proposal, a failure to vote, a broker non-vote or an abstention will have no effect on the outcome of the applicable vote, because approval requires only that the votes cast “FOR” exceed the votes cast “AGAINST,” and abstentions and broker non-votes are not counted as votes cast.

Q:     What shares can I vote at the special meeting?

A:     The AIR Board has fixed the close of business on [•], 2026, as the record date for the special meeting. Only holders of record of the outstanding shares of AIR common stock at the close of business on the record date for the special meeting are entitled to vote at the special meeting or any adjournments thereof.

As of the close of business on the record date for the special meeting, we had [•] shares of AIR common stock issued and outstanding. A holder of shares of AIR common stock is entitled to one vote, in person or by proxy, for each share of AIR common stock on all matters properly brought before the special meeting.

Q:     How many shares must be present or represented to conduct business at the special meeting?

A:     The presence, in person or by proxy, of the holders of 33⅓% in voting power of the outstanding shares of stock entitled to vote at the special meeting or any adjournment thereof is necessary to constitute a quorum to transact business. However, approval of the written consent proposal requires that the holders of at least a majority of the voting power of the outstanding shares of AIR common stock outstanding as of the record date for the special meeting vote in favor of the written consent proposal. Accordingly, approval of the written consent proposal will require the participation of a greater number of AIR stockholders than the minimum needed to establish a quorum.

Table of Contents

Abstentions and broker non-votes (shares held by brokers, trustees or other nominees as to which they have no discretionary power to vote on a particular matter and have received no instructions from the beneficial owners of such shares or persons entitled to vote on the matter) will be counted as present at the special meeting for the purpose of determining whether a quorum is present. If your shares are held by a broker, trustee or other nominee on your behalf and you do not instruct the broker, trustee or other nominee as to how to vote these shares on Proposal 1 (the stock issuance proposal), Proposal 2 (the authorized shares proposal), Proposal 3 (the written consent proposal), Proposal 4 (the transaction compensation proposal) and Proposal 5 (the adjournment proposal), the broker, trustee or other nominee may not exercise discretion to vote for or against those proposals. This would be a “broker non-vote”. For Proposal 1 (the stock issuance proposal), Proposal 2 (the authorized shares proposal), Proposal 4 (the transaction compensation proposal) and Proposal 5 (the adjournment proposal), these shares will not be counted as having been voted and therefore will have no effect on the vote for that proposal, assuming a quorum is present. For Proposal 3 (the written consent proposal), a broker non-vote will have the same effect as a vote “AGAINST” such proposal. Please instruct your broker, trustee or other nominee so your vote can be counted.

Q:     How can I vote my shares at the special meeting?

A:     Shares held in your name as the stockholder of record may be voted in person at the special meeting. Shares for which you are the beneficial owner, but not the stockholder of record, may be voted in person at the special meeting only if you obtain a legal proxy from the broker, trustee or nominee that holds your shares giving you the right to vote the shares.

Even if you plan to attend the special meeting, we recommend that you also vote by proxy as described below so that your vote will be counted if you later decide not to attend the special meeting. Voting in person at the special meeting will revoke any previously submitted proxy.

Q:     How can I vote my shares without attending the special meeting?

A:     If you are a stockholder as of the record date for the special meeting, you may cast your vote in one of the following ways:

By Internet — Stockholders who have received a proxy card or voting instruction form may vote over the Internet by visiting the website indicated and following the instructions on the proxy card or voting instruction form.

By Telephone — Stockholders of record who live in the United States or Canada may submit proxies by telephone by calling 1-800-690-6903 and following the instructions. Stockholders of record who have received a proxy card by mail must have the control number that appears on their proxy card available when voting. Most stockholders who are beneficial owners of their shares, but not stockholders of record, living in the United States or Canada and who have received a voting instruction form may vote by phone, by calling the number specified on the voting instruction form provided by their broker, trustee or nominee. Those stockholders should check the voting instruction form for telephone voting availability.

By Mail — Stockholders who have received a proxy card or voting instruction form may submit proxies by completing, signing and dating their proxy card or voting instruction form and mailing it in the accompanying pre-addressed envelope.

Telephone and Internet voting facilities for stockholders of record will be available 24 hours a day and will close at 11:59 P.M. (Eastern Time) on [•], 2026. Votes cast by mail must be received in sufficient time to allow processing. Shares represented by duly executed proxies in the accompanying proxy card or voting instruction form will be voted in accordance with the instructions indicated on such proxies or voting instruction forms and, if no such instructions are indicated thereon, will be voted (i) FOR the stock issuance proposal, (ii) FOR the authorized shares proposal, (iii) FOR the written consent proposal, (iv) FOR the transaction compensation proposal and (v) FOR the adjournment proposal.

Q:     What if I want to change my vote?

A:     If the enclosed proxy card or voting instruction form is signed and returned, you may, nevertheless, revoke it at any time prior to the special meeting by (i) filing a written notice of revocation with the person or persons named on the proxy card or voting instruction form; (ii) attending the special meeting and voting the shares covered thereby in person; or (iii) delivering to the addressee named in the enclosed proxy card or voting instruction form another duly executed proxy card or voting instruction form dated subsequent to the date of the proxy card or voting instruction form to be revoked.

Q:     When and where is the special meeting?

A:     The special meeting will be held at 1460 Fifth Avenue, Bay Shore, New York 11706 on [•], 2026, at [•] [A.M./P.M.], Eastern Time, or at any adjournments thereof, for the purposes stated in the Notice of Special Meeting of Stockholders.

Q:     Do I need a ticket to attend the special meeting?

A:     If you plan to attend the special meeting in person:    You will need an admission ticket or proof of ownership of our common stock to enter the special meeting. If you hold shares directly in your name as a stockholder of record and have received a copy of our proxy materials, an admission ticket is attached to your printed proxy card. If you plan to attend the special meeting, please vote your proxy prior to the special meeting but keep the admission ticket and bring it with you to the special meeting.

If your shares are held beneficially in the name of a broker, trustee or other nominee and you wish to be admitted to the special meeting, you will have to bring either a copy of the voting instruction form provided by your broker, trustee or other nominee, or a copy of a brokerage statement showing your ownership of our common stock as of [•], 2026.

If you are representing an entity holding shares, then you must present a proxy signed by that entity evidencing that you are authorized to attend the special meeting and vote the shares or are otherwise representing the entity at the special meeting. If you are representing an entity whose shares are held beneficially in the name of a broker, trustee or other nominee, you will have to bring either a copy of the voting instruction form provided by such entity’s broker, trustee or other nominee, or a copy of a brokerage statement showing the entity’s ownership of our common stock as of [•], 2026, in addition to the proxy signed by the entity you are representing.

All stockholders must also present a form of photo identification, such as a valid driver’s license or passport, in order to be admitted to the special meeting.

Q:     What should I do if I receive more than one copy of the proxy materials?

A:     You may receive more than one copy of the proxy materials, including multiple paper copies of this proxy statement/prospectus and multiple proxy cards or voting instruction forms.

For example, if you hold your shares in more than one brokerage account, you may receive a separate voting instruction form for each brokerage account in which you hold shares. If you are a stockholder of record and your shares are registered in more than one name, you may receive more than one proxy card. If you hold your shares through a broker, trustee or another nominee, rather than owning shares registered directly in your name, you are considered the beneficial owner of shares held in street name. As the beneficial owner, you are entitled to direct the voting of your shares by your intermediary. Your intermediary will forward the proxy materials to you with a voting instruction form or provide electronic access to the materials and to voting facilities. To vote all of your shares by proxy, you must complete, sign, date and return each proxy card and voting instruction form that you receive.

Transitory Air Sub LLC
1460 Fifth Avenue
Bay Shore, NY 11706
(631) 968-5000

Merger Sub was formed solely for the purpose of facilitating the merger and the Transactions. Merger Sub has not carried on any activities or operations to date, except for those activities incidental to its formation and undertaken in connection with the merger and the Transactions. Pursuant to the merger agreement, at the effective time, Merger Sub will be merged with and into Tenax, with Tenax surviving the merger as a wholly owned subsidiary of AIR.

The Merger (page 38)

The terms and conditions of the merger are contained in the merger agreement, which is included in this proxy statement/prospectus as Annex A and is incorporated herein by reference in its entirety. The rights and obligations of each of Tenax, AIR and Merger Sub are governed by the express terms and conditions of the merger agreement and not by this summary or any other information contained in this proxy statement/prospectus.

Conversion of Securities; Adjustments to the Merger Consideration (page 38)

At the effective time, Tenax units issued and outstanding immediately prior to the effective time will be converted into the right to receive the portion of the merger consideration allocated in respect thereof. Pursuant to the merger agreement, the merger consideration will consist of 126,900,000 shares (which number will be adjusted to 25,380,000 shares after giving effect to the proposed amendment to the articles of incorporation of AIR contemplated by the authorized shares proposal and the subsequent reverse stock split, each as described in this proxy statement/prospectus) of AIR common stock to be issued to the Tenax Members and, as applicable, reserved for issuance to the Tenax Warrantholders upon the exercise of their warrants. The allocation of the merger consideration among the Tenax Members will be set forth in the capitalization schedule, which Tenax is required to deliver no less than two business days prior to the closing.

Ownership of AIR Following the Merger (page 38)

As a result of the merger, the AIR stockholders as of immediately prior to the effective time will collectively own approximately 4% of the outstanding shares of AIR common stock, on a fully diluted basis, and the Tenax Members and Tenax Warrantholders will collectively own approximately 96% of the outstanding shares of AIR common stock, on a fully diluted basis. Accordingly, the merger will result in substantial dilution to existing AIR stockholders, and the Tenax Members will have a controlling interest in AIR following completion of the merger. Following the merger, AIR will remain a publicly traded corporation, and shares of AIR common stock will continue to be listed on the NYSE American.

A portion of the merger consideration is allocable to holders of warrants of Tenax, referred to as the Tenax Warrantholders. AIR will reserve for future issuance, upon exercise of the warrants, a number of shares of AIR common stock equal to the total merger consideration that would be payable to the Tenax Warrantholders if all Tenax Warrantholders exercised their warrants (if and to the extent they remain outstanding) immediately prior to the effective time.

Governance of AIR Following the Merger (page 62)

Board of Directors

Following the consummation of the merger, the AIR Board will be composed of no fewer than eight directors, which shall consist only of (a) no fewer than six individuals designated by Tenax, namely Thomas Foley, Taran Bakker, Michael Ewald, Donald Fawcett, Bryan Fenton, DeWolfe Miller and John Young, and (b) two individuals to be mutually agreed upon by Tenax and AIR, namely [•] and [•], to hold office in accordance with the articles of incorporation and bylaws of AIR.

Michael Ewald, Donald Fawcett, Bryan Fenton, DeWolfe Miller, John Young, [•] and [•] are expected to be “independent directors” within the meaning of Item 407(a)(1) and NYSE American Rule 803A(2).

Following the consummation of the merger, the audit committee of the AIR Board (the “Audit Committee”) will be composed of members who meet the independence requirements set forth by the SEC, in the NYSE American listing requirements and the Audit Committee charter. Each member of the Audit Committee will be financially literate in accordance with the NYSE American listing requirements.

For more information, see the section entitled “Management and Directors of the Combined Company” beginning on page 146 of this proxy statement/prospectus.

Management

AIR’s executive team following the merger will draw on the leadership teams of AIR and Tenax. In particular, Jim Linder, Ignacio Ladegui and Alan Oswalt, current executive officers of Tenax, will become Chief Executive Officer, Chief Financial Officer and EVP of Operations, respectively, of the combined company.

Tenax and its members, through the date on which the merger agreement was signed by all parties, made no arrangements with, and made no offers to, any members of AIR’s management team regarding continued employment with AIR.

Table of Contents

For more information, see the section entitled “Management and Directors of the Combined Company” beginning on page 146 of this proxy statement/prospectus.

Controlled Company

Following the consummation of the merger, AIR will be a “controlled company” for purposes of Section 801(a) of the NYSE American Company Guide and, if and for so long as it so qualifies, intends to rely on exemptions from certain governance standards.

Under Section 801(a), a company in which over 50% of the voting power is held by an individual, a group or another company is a “controlled company” and is exempt from certain corporate governance requirements, including requirements that (1) a majority of AIR’s board of directors consist of independent directors, (2) director nominees be selected or recommended for selection by a majority of the independent directors or by a nominating committee composed solely of independent directors and (3) compensation of the chief executive officer be determined or recommended to the board of directors by a majority of its independent directors or by a compensation committee composed of independent directors. The controlled company exemption does not modify the independence requirements for the Audit Committee, and AIR intends to continue to comply with the requirements of the NYSE American rules with respect thereto.

Smaller Reporting Company

Following the consummation of the merger, AIR is expected to qualify as a “Smaller Reporting Company” for purposes of Section 801(h) of the NYSE American Company Guide and, if and for so long as it so qualifies, intends to rely on exemptions from certain governance standards.

Under Section 801(h), a company that satisfies the definition of smaller reporting company in Rule 12b-2 of the Exchange Act, meaning it is an issuer that is not an investment company, an asset-backed issuer or a majority-owned subsidiary of a parent that is not a smaller reporting company and that (1) has a public float of less than $250 million or (2) has annual revenues of less than $100 million and either (i) no public float or (ii) a public float of less than $700 million, is a “Smaller Reporting Company”. Smaller Reporting Companies are only required to maintain a board of directors composed of at least 50% independent directors (rather than a majority of independent directors) and an audit committee of at least two independent members (rather than three independent members). In addition, Smaller Reporting Companies are not subject to the same independence requirements for the compensation committee and compensation consultants.

Recommendation of the AIR Board; AIR’s Reasons for the Merger (page 48)

After careful consideration, the AIR Board unanimously (i) determined that the merger agreement and the Transactions are fair to and in the best interests of AIR and its stockholders and (ii) adopted and approved the merger agreement and the Transactions, on the terms and subject to the conditions set forth in the merger agreement. Accordingly, the AIR Board unanimously recommends that AIR’s stockholders vote “FOR” the stock issuance proposal, the authorized shares proposal, the written consent proposal, the transaction compensation proposal and the adjournment proposal. For more information on AIR’s reasons for the merger and the recommendation of the AIR Board, see the section entitled “The Merger — Recommendation of the AIR Board; AIR’s Reasons for the Merger” beginning on page 48 of this proxy statement/prospectus.

Opinion of AIR’s Financial Advisor (page 53)

AIR retained Kipps to act as its financial advisor in connection with the Transactions. As part of this engagement, the AIR Board requested that Kipps evaluate the fairness to the holders of the AIR common stock, from a financial point of view, of the unadjusted redemption price. At the meeting of the AIR Board on February 13, 2026, Kipps rendered its oral opinion to the AIR Board that as of the date of such opinion and based upon and subject to the assumptions, limitations, qualifications and conditions described in Kipps’s written opinion, an unadjusted redemption price of $4.21 was fair, from a financial point of view, to the holders of the AIR common stock. On February 17, 2026, Kipps delivered to the AIR Board a written opinion and an updated presentation, each dated February 17, 2026, confirming that, as of the date of such opinion and based upon and subject to the assumptions, limitations, qualifications and conditions described in such opinion, an unadjusted redemption price of $4.18 was fair, from a financial point of view, to the holders of the AIR common stock.

Table of Contents

AIR stockholders should be aware that Kipps’s written opinion was based on an assumed unadjusted redemption price of $4.18 per share, which was calculated at the direction of AIR’s management based on a formula set forth in the original merger agreement. The actual redemption price will be materially lower than the price per share on which Kipps rendered its fairness opinion.

The full text of the written opinion of Kipps, dated February 17, 2026, which sets forth, among other things, the procedures followed, assumptions made, matters considered and qualifications and limitations on the scope of review undertaken in rendering its opinion, is attached as Annex B and is incorporated herein by reference into this proxy statement/prospectus in its entirety. The summary of the opinion of Kipps in this proxy statement/prospectus is qualified in its entirety by reference to the full text of the written opinion. You are urged to read Kipps’s opinion carefully and in its entirety. Kipps’s opinion was addressed to, and provided for the information and benefit of, the AIR Board (in its capacity as such) in connection with its evaluation of the Original Transactions. The opinion does not constitute a recommendation to the AIR Board or to any other persons in respect of the Original Transactions or the Transactions, including as to how any holder of shares of AIR common stock should vote or act in respect of the Original Transactions or the Transactions. Kipps’s opinion does not address the relative merits of the Original Transactions or the Transactions as compared to other business or financial strategies that might be available to AIR, nor does it address the underlying business decision of AIR to engage in the Original Transactions or the Transactions.

For more information, see the section entitled “The Merger — Opinion of AIR’s Financial Advisor” beginning on page 53 of this proxy statement/prospectus and the full text of the written opinion of Kipps attached as Annex B to this proxy statement/prospectus.

Tenax’s Reasons for the Merger (page 61)

In evaluating the merger and the other Transactions, the Tenax Board, in consultation with Tenax’s management and advisors, considered a number of factors weighing both in favor of and against the merger and approved the merger agreement and the Transactions. In particular, the Tenax Board believed the merger would combine Tenax with an established, publicly traded aerospace and defense company to create a platform with broader capabilities, customer relationships and growth opportunities than Tenax would have on a stand-alone basis.

For more information, see the section entitled “The Merger — Tenax’s Reasons for the Merger” beginning on page 61 of this proxy statement/prospectus.

Information About the Special Meeting (page 34)

The special meeting will be held on [•], 2026, at [•] [A.M./P.M.], Eastern Time, at 1460 Fifth Avenue, Bay Shore, New York 11706. The special meeting is being held in order to vote on the stock issuance proposal, the authorized shares proposal, the written consent proposal, the transaction compensation proposal and the adjournment proposal. The merger cannot be completed unless the stock issuance proposal, the authorized shares proposal and the written consent proposal are approved by our stockholders.

The following voting requirements will be in effect for each proposal described in this proxy statement/prospectus:

        Approval of the stock issuance proposal requires that the number of shares voted “FOR” the stock issuance proposal must exceed the number of votes cast “AGAINST” the stock issuance proposal. Abstentions and broker non-votes will have no effect.

        Approval of the authorized shares proposal requires that the number of shares voted “FOR” the authorized shares proposal must exceed the number of votes cast “AGAINST” the authorized shares proposal. Abstentions and broker non-votes will have no effect.

        Approval of the written consent proposal requires the affirmative vote of the holders of shares representing at least a majority of the voting power of the outstanding shares of AIR common stock entitled to vote thereon as of the record date for the special meeting. A failure to vote, a broker non-vote or an abstention will each have the same effect as a vote “AGAINST” this proposal.

Table of Contents

        Approval of the transaction compensation proposal (on a non-binding, advisory basis) requires that the number of shares voted “FOR” the transaction compensation proposal must exceed the number of votes cast “AGAINST” the transaction compensation proposal. Abstentions and broker non-votes will have no effect.

        Approval of the adjournment proposal requires that the number of shares voted “FOR” the adjournment proposal must exceed the number of votes cast “AGAINST” the adjournment proposal. Abstentions and broker non-votes will have no effect.

The AIR Board has fixed the close of business on [•], 2026, as the record date for the special meeting. Only holders of record of the outstanding shares of AIR common stock at the close of business on the record date for the special meeting are entitled to vote at the special meeting or any adjournments thereof.

As of the close of business on the record date for the special meeting, we had [•] shares of AIR common stock issued and outstanding. A holder of shares of AIR common stock is entitled to one vote, in person or by proxy, for each share of AIR common stock on all matters properly brought before the special meeting.

Interests of AIR’s Directors and Executive Officers in the Merger (page 50)

In considering the recommendation of the AIR Board, AIR stockholders should be aware that certain directors and executive officers of AIR have interests in the Transactions that may be different from, or in addition to, the interests they may have as stockholders. Specifically, Michael Taglich and Robert Taglich, directors of AIR, hold subordinated notes, which will be repaid at closing pursuant to the merger agreement. In addition, AIR RSUs and AIR stock option awards (collectively, “AIR Equity Awards”) issued under the AIR Stock Plans and associated award agreements will continue on the same terms and conditions, and will be eligible for accelerated vesting upon a termination without “cause” within two years following the effective time. Pursuant to the terms of the applicable award agreements, certain holders may also be entitled to additional time in which to exercise any stock options if their engagement by AIR is terminated under prescribed circumstances. As of July 10, 2026, AIR’s directors and executive officers beneficially owned, in the aggregate, approximately 28.44% of the shares of AIR common stock, including shares of AIR common stock issuable upon exercise or settlement of AIR Equity Awards. All directors and executive officers of AIR have entered into a support agreement in connection with the merger to vote all shares of AIR common stock owned by them as of the record date in favor of the stock issuance proposal, the authorized shares proposal and the written consent proposal.

The members of the AIR Board were aware of and considered the interests discussed in the preceding paragraph, among other matters, in evaluating and negotiating the merger agreement, in approving the merger agreement and in determining to recommend that stockholders approve the stock issuance proposal, the authorized shares proposal and the written consent proposal. For more information, see the section entitled “The Merger — Interests of AIR’s Directors and Executive Officers in the Merger” beginning on page 50 of this proxy statement/prospectus.

Interests of Certain Participants in the Solicitation (page 53)

Our directors and executive officers may solicit proxies by telephone or otherwise in respect of the proposals to be considered at the special meeting and may be deemed to be “participants” under the SEC rules in regard to such solicitation of AIR stockholders. AIR stockholders should be aware that all of the directors and Messrs. Glassman and Drisgula have interests in the merger that may be different from, or in addition to, those of AIR stockholders generally. All of our directors and Mr. Glassman will benefit from the treatment of outstanding AIR RSUs and AIR stock options, and Michael Taglich and Robert Taglich will benefit from the payment of subordinated notes held by them as more fully described under “The Merger — Interests of AIR’s Directors and Executive Officers in the Merger” beginning on page 50 of this proxy statement/prospectus. In addition, AIR’s directors and executive officers will benefit from the indemnification and insurance arrangements described under “The Merger Agreement — Directors’ and Officers’ Indemnification and Insurance” beginning on page 77 of this proxy statement/prospectus.

For more information, see the section entitled “The Merger — Interests of Certain Participants in the Solicitation” beginning on page 53 of this proxy statement/prospectus.

Interests of Tenax’s Managers and Executive Officers in the Merger (page 62)

Certain members of the Tenax Board and certain of Tenax’s executive officers have interests in the merger that are different from, or in addition to, the interests of Tenax Members generally.

Thomas Foley and Taran Bakker are currently members of the Tenax Board and are expected to become directors of the combined company upon the closing of the merger. Jim Linder, Ignacio Ladegui and Alan Oswalt are currently executive officers of Tenax and are expected to become executive officers of the combined company, in connection with which they may enter into new employment agreements to reflect their status as executive officers of a publicly-traded company. Following completion of the merger, it is expected that the combined company will provide compensation to non-employee directors pursuant to a new non-employee director compensation policy that is expected to be adopted post-closing.

As of June 30, 2026, Tenax’s then-current non-employee managers and executive officers beneficially owned (indirectly through membership interests in NEH and Managers Equity, LLC), in the aggregate, approximately 78% of the Tenax units. Such Tenax units will be converted into shares of AIR common stock at the effective time.

For more information, see the section entitled “The Merger — Interests of Tenax’s Managers and Executive Officers in the Merger” beginning on page 62 of this proxy statement/prospectus.

Regulatory Approvals (page 64)

Completion of the merger is conditioned on, among other things, the expiration or termination of the applicable waiting periods under the HSR Act, the receipt of any required approvals or the expiration or termination of any applicable waiting periods under Antitrust Laws of certain other specified jurisdictions, if applicable, and the absence of any law or order enacted, issued, promulgated, enforced or entered, whether temporary, preliminary or permanent, which is then in effect and has the effect of enjoining, restraining, prohibiting or otherwise preventing consummation of the Transactions.

Pursuant to the merger agreement, each party has agreed to use its reasonable best efforts to obtain all necessary actions or nonactions, consents, approvals and waivers from, and to give any necessary notices to, governmental authorities and to make all necessary registrations, declarations and filings (including filings that are required or advisable under the HSR Act and other registrations, declarations and filings with, or notices to, governmental authorities that may be required or advisable under other applicable antitrust, competition or pre-merger notification laws of any jurisdiction), if any.

On May 15, 2026, Thomas Foley filed a notification and report form pursuant to the HSR Act with the FTC and the DOJ with respect to his proposed acquisition of AIR common stock in connection with the merger. The applicable waiting period expired on June 15, 2026.

There can be no assurance that a challenge to the Transactions on antitrust grounds will not be made or, if such a challenge is made, what the result will be. The required regulatory and other approvals are discussed under the section entitled “The Merger Agreement — Covenants and Agreements — Reasonable Best Efforts; Further Action” beginning on page 78 of this proxy statement/prospectus.

No Solicitation by AIR (page 73)

The merger agreement provides that neither AIR nor any of its subsidiaries nor any of their respective representatives will, and that AIR will cause its subsidiaries and their respective representatives not to, directly or indirectly:

        solicit, initiate, seek or take any other action to facilitate or encourage the making, submission or announcement of any proposal that constitutes, or could reasonably be expected to lead to any Competing AIR Proposal (as defined under “The Merger Agreement — Covenants and Agreements — No Solicitation by AIR”);

        enter into, maintain, continue or participate in any discussions or negotiations with any person or entity in furtherance of, or furnish to any person any information or otherwise cooperate in any way with respect to, any Competing AIR Proposal;

6

Table of Contents

        agree to, approve, endorse, recommend or consummate any Competing AIR Proposal;

        enter into, or propose to enter into, any contract or agreement which could reasonably be expected to lead to any Competing AIR Proposal (other than an acceptable confidentiality agreement); or

        resolve, propose or agree, or authorize or permit any representative, to do any of the foregoing.

AIR is required to promptly (and in any event within 24 hours of receipt) advise Tenax orally and in writing of any Competing AIR Proposal or any inquiry relating to or that could reasonably be expected to lead to any Competing AIR Proposal, including the material terms and conditions of any such Competing AIR Proposal or inquiry and the identity of the person making any such Competing AIR Proposal or inquiry, to keep Tenax reasonably informed of the status and material details of any such Competing AIR Proposal or inquiry and provide Tenax, as soon as practicable after receipt or delivery thereof (and in any event within 24 hours of such receipt or delivery), copies of all correspondence and other written material versions of agreements relating to any such Competing AIR Proposal exchanged between AIR or any of its subsidiaries, on the one hand, and the person making the Competing AIR Proposal or inquiry (or its representatives), on the other hand.

Notwithstanding the above, AIR may, subject to compliance with the terms of the merger agreement, furnish information to, and enter into discussions with, a person who has made, after February 16, 2026, an unsolicited, written, bona fide Competing AIR Proposal, so long as such Competing AIR Proposal did not result from a breach of the merger agreement and prior to furnishing such information and entering into such discussions, the AIR Board:

        reasonably determines, in its good faith judgment (after receiving the advice of a financial advisor of nationally recognized reputation and outside legal counsel qualified to practice in the State of Nevada and experienced in matters of Nevada corporate law) that such Competing AIR Proposal constitutes, or could reasonably be expected to lead to, a Superior Proposal (as defined under “The Merger Agreement — Covenants and Agreements — No Solicitation by AIR”) and the failure to furnish such information to, or enter into such discussions with, the person who made such Competing AIR Proposal would violate the AIR Board’s fiduciary duties under the NRS;

        provides such information to Tenax (or provides such information to Tenax substantially concurrent with the time it is provided to such person); and

        obtains from such person a confidentiality agreement that contains terms no less favorable to AIR than those contained in the existing confidentiality agreement between AIR and Tenax.

Change in the AIR Recommendation (page 74)

The AIR Board has recommended that the AIR stockholders vote in favor of approving the stock issuance proposal, the authorized shares proposal and the written consent proposal (the “AIR Recommendation”). The merger agreement provides that, subject to the exceptions described below, neither the AIR Board nor any committee thereof may make a Change in the AIR Recommendation (as defined under “The Merger Agreement — Covenants and Agreements — Change in the AIR Recommendation”).

Notwithstanding the foregoing, prior to the receipt of the requisite AIR stockholder approvals, the AIR Board may make a Change in the AIR Recommendation if, in response to the receipt of an unsolicited, written, bona fide Competing AIR Proposal received after February 16, 2026 or the occurrence of an Intervening Event (as defined under “The Merger Agreement — Covenants and Agreements — Change in the AIR Recommendation”), the AIR Board determines in its good-faith judgment (after having received the advice of a financial advisor of nationally recognized reputation and outside legal counsel qualified to practice in the State of Nevada and experienced in matters of Nevada corporate law) that its failure to make a Change in the AIR Recommendation would violate the fiduciary duties of the AIR Board under the NRS; provided, however, that no such action may be taken unless:

        if the AIR Board is making a Change in the AIR Recommendation relating to a Competing AIR Proposal, such Competing AIR Proposal is a Superior Proposal;

        AIR provides written notice to Tenax that the AIR Board intends to make a Change in the AIR Recommendation, specifies the reasons therefor, including a description of any Intervening Event in reasonable detail or the terms and conditions of any Superior Proposal, and includes an unredacted copy of any proposed agreement relating to such Superior Proposal;

7

Table of Contents

        AIR provides a period of five business days following Tenax’s receipt of such notice during which AIR will negotiate in good faith with Tenax regarding any revisions to the terms of the merger agreement proposed by Tenax (provided that any material change regarding such Intervening Event, or any amendments to the financial terms or any other material term of such Superior Proposal will require a new notice period of three business days); and

        at the end of such notice period, the AIR Board again makes a determination in good faith after consultation with its outside legal counsel and financial advisors (and taking into account any adjustment or modification of the terms of the merger agreement proposed by Tenax) that the Competing AIR Proposal continues to be a Superior Proposal and that the Change in the AIR Recommendation is required to comply with the AIR Board’s fiduciary duties under the NRS.

No Solicitation by Tenax (page 76)

The merger agreement provides that neither Tenax nor any of its subsidiaries nor any of their respective representatives will, and that Tenax will cause its subsidiaries and their respective representatives not to, directly or indirectly:

        solicit, initiate, seek or take any other action to facilitate or encourage the making, submission or announcement of any proposal that constitutes, or could reasonably be expected to lead to any Competing Tenax Proposal (as defined under “The Merger Agreement — Covenants and Agreements — No Solicitation by Tenax”);

        enter into, maintain, continue or participate in any discussions or negotiations with any person or entity in furtherance of, or furnish to any person any information or otherwise cooperate in any way with respect to, any Competing Tenax Proposal;

        agree to, approve, endorse, recommend or consummate any Competing Tenax Proposal;

        enter into, or propose to enter into, any contract or agreement which could reasonably be expected to lead to any Competing Tenax Proposal (other than an acceptable confidentiality agreement); or

        resolve, propose or agree, or authorize or permit any representative, to do any of the foregoing.

Tenax is required to promptly (and in any event within 24 hours of receipt) advise AIR orally and in writing of any Competing Tenax Proposal or any inquiry relating to or that could reasonably be expected to lead to any Competing Tenax Proposal, including the material terms and conditions of any such Competing Tenax Proposal or inquiry and the identity of the person making any such Competing Tenax Proposal or inquiry, to keep AIR reasonably informed of the status and material details of any such Competing Tenax Proposal or inquiry and provide AIR, as soon as practicable after receipt or delivery thereof (and in any event within 24 hours of such receipt or delivery), copies of all correspondence and other written material versions of agreements relating to any such Competing Tenax Proposal exchanged between Tenax or any of its subsidiaries, on the one hand, and the person making the Competing Tenax Proposal or inquiry (or its representatives), on the other hand.

Notwithstanding the above, Tenax may, subject to compliance with the terms of the merger agreement, furnish information to, and enter into discussions with, a person who has made, after February 16, 2026, an unsolicited, written, bona fide Competing Tenax Proposal, so long as such Competing Tenax Proposal did not result from a breach of the merger agreement and prior to furnishing such information and entering into such discussions, the board of managers of Tenax (the “Tenax Board”) obtains from such person a confidentiality agreement that contains terms no less favorable to Tenax than those contained in the existing confidentiality agreement between AIR and Tenax.

        by either AIR or Tenax, following a meeting of the AIR stockholders at which the AIR stockholders fail to approve the stock issuance proposal, the authorized shares proposal and the written consent proposal;

        by either AIR or Tenax, if any Restraint that has the effect of enjoining, restraining, prohibiting or otherwise preventing the consummation of the Transactions has become final and non-appealable (provided that the party seeking to terminate the merger agreement pursuant to this bullet point has complied in all material respects with its covenants and agreements under the merger agreement regarding the use of efforts to consummate the Transactions);

        by either AIR or Tenax, if the effective time has not occurred on or before the Outside Date (as defined under “The Merger Agreement — Termination of the Merger Agreement”) (provided that the right to terminate the merger agreement pursuant to this bullet point will not be available to (i) any party whose failure to fulfill any obligation under the merger agreement or intentional breach has been a material cause of, or resulted in, the failure of the effective time to occur on or before such time; (ii) AIR if any AIR stockholder party to the AIR Stockholder Support Agreement (the “Key AIR Stockholders”) has materially breached its obligations under the AIR Stockholder Support Agreement and such breach has been a material cause of, or resulted in, the failure of the effective time to occur on or before such time; or (iii) Tenax if any Tenax Member has materially breached its obligations under the Tenax Member Support Agreement and such breach has been a material cause of, or resulted in, the failure of the effective time to occur on or before such time);

        by Tenax, upon a breach by either of AIR or Merger Sub of, or a failure by AIR or Merger Sub to perform, any representation, warranty, covenant or agreement set forth in the merger agreement such that the related closing conditions would not be satisfied, and such breach or failure is incapable of being cured by the Outside Date or, if curable by the Outside Date, is not cured within 30 days of receipt by AIR or Merger Sub, as applicable, of written notice of such breach or failure (provided that Tenax will not have the right to terminate the merger agreement pursuant to this bullet point if Tenax is in material breach of its representations, warranties or covenants at the time of such termination);

        by Tenax, if a Change in the AIR Recommendation shall have occurred;

        by AIR, upon a breach by Tenax of, or a failure by Tenax to perform, any representation, warranty, covenant or agreement set forth in the merger agreement such that the related closing conditions would not be satisfied, and such breach or failure is incapable of being cured by the Outside Date or, if curable by the Outside Date, is not cured within 30 days of receipt by Tenax of written notice of such breach or failure (provided that AIR will not have the right to terminate the merger agreement pursuant to this bullet point if AIR is in material breach of its representations, warranties or covenants at the time of such termination);

Expenses and Termination Fees (page 82)

Expenses

All expenses incurred in connection with the merger agreement and the Transactions will be paid by the party incurring such expenses, whether or not the merger or any other Transaction is consummated, except that expenses constituting the out-of-pocket cost of filing fees, printing and mailing of this proxy statement/prospectus (excluding, for the avoidance of doubt, the fees and expenses of AIR’s legal counsel) and the filing fees for the pre-merger notification and report forms under the HSR Act (excluding, for the avoidance of doubt, the fees and expenses of AIR’s legal counsel) will be paid by Tenax.

Termination Fees and Expense Reimbursement

The merger agreement requires AIR to pay Tenax an amount equal to $1,250,000 (the “AIR Termination Fee”) if:

        AIR terminates the merger agreement to accept a Superior Proposal;

        Tenax terminates the merger agreement following a Change in the AIR Recommendation; or

        each of the following requirements are satisfied:

        either AIR or Tenax terminates the merger agreement following a meeting of the AIR stockholders at which the AIR stockholders fail to approve the stock issuance proposal, the authorized shares proposal and the written consent proposal; or AIR or Tenax terminates the merger agreement if the effective time has not occurred by 11:59 P.M., Eastern Time, on the Outside Date; or Tenax terminates the merger agreement upon a breach by AIR or Merger Sub of, or a failure by AIR or Merger Sub to perform, any representation, warranty, covenant or agreement set forth in the merger agreement such that the related closing conditions would not be satisfied by the Outside Date (provided that Tenax is not in material breach of any of its representations, warranties or covenants);

        prior to such termination, a Competing AIR Proposal has been publicly announced or become publicly known; and

        AIR enters into a definitive agreement in respect of such Competing AIR Proposal and such transaction is consummated within 12 months after such termination.

If either AIR or Tenax terminates the merger agreement following a meeting of the AIR stockholders at which the AIR stockholders fail to approve the stock issuance proposal, the authorized shares proposal and the written consent proposal, AIR shall further reimburse Tenax for Tenax’s reasonable and documented out-of-pocket costs and expenses incurred in connection with the merger agreement and the Transactions, up to $500,000.

The merger agreement requires Tenax to pay AIR an amount equal to $1,250,000 (the “Tenax Termination Fee”) if:

        AIR terminates the merger agreement upon a breach by Tenax of, or a failure by Tenax to perform, any representation, warranty, covenant or agreement set forth in the merger agreement such that the related closing conditions would not be satisfied by the Outside Date (provided that AIR is not in material breach of any of its representations, warranties or covenants);

Other Related Agreements (page 85)

Redemption Rights Agreement

Prior to the closing, AIR will declare and issue, as a dividend to AIR stockholders as of the trading day immediately preceding the closing date, a right to cause AIR to redeem shares of AIR common stock that such AIR stockholders then own and continue to own on the first anniversary of the closing. The Redemption Rights will entitle the holders thereof to require AIR to purchase all or a portion of such AIR stockholder’s shares of AIR common stock for a redemption price, payable in cash, equal to 107.3% of the Debt Adjusted AIR Share Price, if the volume weighted average price of AIR common stock during the 20 trading days preceding the first anniversary of the closing is lower than 107.3% of the Debt Adjusted AIR Share Price. The Redemption Rights will not be transferable. See the section entitled “Other Related Agreements — Redemption Rights Agreement” beginning on page 85 of this proxy statement/prospectus.

Registration Rights Agreement

Prior to the closing, AIR, the Tenax Members, the Tenax Warrantholders and NTC Group, as Investors’ Representative, will enter into a registration rights agreement granting (i) Thomas Foley, Chairman of Tenax, and Taran Bakker, a director of Tenax, and certain of their respective affiliates customary demand rights and (ii) the Tenax Members piggyback registration rights, in each case for the resale of the shares of AIR common stock held by the Tenax Members. See the section entitled “Other Related Agreements — Registration Rights Agreement” beginning on page 86 of this proxy statement/prospectus.

Material Contracts Between AIR and Tenax (page 145)

Other than the merger agreement and the other transaction documents described in the section entitled “Other Related Agreements”, neither AIR nor any of its affiliates has been, is or is currently expected to be a party to any material contract or arrangement, or to have had any material relationship, with Tenax or any of its affiliates. See the sections entitled “Material Contracts Between AIR and Tenax” beginning on page 145 of this proxy statement/prospectus and “The Merger — Background of the Merger” beginning on page 39 of this proxy statement/prospectus.

Accounting Treatment (page 64)

The transaction is expected to be accounted for as a reverse acquisition under Financial Accounting Standards Board Accounting Standards Codification (“ASC”) Topic 805, “Business Combinations” (“Topic 805”), with Tenax deemed the accounting acquirer and AIR treated as the accounting acquiree for financial reporting purposes. See the section entitled “Unaudited Pro Forma Condensed Combined Financial Information — Accounting Treatment of the Merger” beginning on page 93 of this proxy statement/prospectus.

Financing of the Merger (page 38)

The merger agreement requires that, at the closing of the merger, Tenax fund the repayment of AIR’s net senior and subordinated debt, amounting in the aggregate to approximately $26.233 million as of May 31, 2026. Tenax relies on loans from a syndicate of banks to fund its operations. As of June 30, 2026, Tenax’s available borrowing capacity under its existing credit facility was $27 million. Tenax intends to seek, and believes it will be able to obtain, the necessary lender approvals to increase its borrowing capacity under its existing credit facility to refinance AIR’s net senior and subordinated debt or to otherwise obtain commitments from its lenders to satisfy its cash requirements at the closing of the merger. In addition, prior to closing, Tenax or one or more of its affiliates (which may include one or more Tenax Members) may, in their discretion, provide interim financial assistance to AIR to support its near-term liquidity needs, including in circumstances where AIR would otherwise require additional working capital or liquidity to continue operations during the period between signing and closing. See the sections entitled “The Merger — Financing of the Merger” beginning on page 38 of this proxy statement/prospectus and “Risk Factors — Risks Relating to the Merger — There can be no assurance that Tenax will be able to secure the financing necessary to repay AIR’s net senior and subordinated debt in a timely manner or at all.” beginning on page 16 of this proxy statement/prospectus.

Table of Contents

Reverse Stock Split (page 39)

As of the date of this proxy statement/prospectus, the trading price of AIR’s common stock on the NYSE American is less than $4.00 per share, and there is no assurance that it will not be below $4.00 per share at the effective time, meaning that the combined company would not satisfy the $4.00 minimum share price requirement for initial listing on the NYSE American under Section 101 of the NYSE American Company Guide. As a result, prior to the closing but, assuming the authorized shares proposal is approved at the special meeting, after the related amendment to the articles of incorporation of AIR becomes effective, AIR will file a certificate of change with the Nevada Secretary of State to effect, pursuant to NRS 78.207, a reverse stock split of the issued and outstanding shares of AIR common stock at a ratio of one (1) post-split share of AIR common stock for every five (5) pre-split shares of AIR common stock, while simultaneously reducing the number of authorized shares of AIR common stock under the articles of incorporation of AIR by a corresponding factor, with any fractional share of AIR common stock otherwise resulting from the split rounded up to the nearest whole share. Pursuant to NRS 78.207, the AIR Board has the authority to effect such a reverse stock split without stockholder approval. See the sections entitled “The Merger — Reverse Stock Split” beginning on page 39 of this proxy statement/prospectus and “Risk Factors — Risks Relating to the Merger — If the combined company fails to comply with the initial listing requirements of the NYSE American, shares of AIR common stock could face possible delisting, which would result in, among other things, a limited public market for shares of AIR common stock and make obtaining future debt or equity financing more difficult for us.” beginning on page 24 of this proxy statement/prospectus.

Comparison of Rights of AIR Stockholders and Tenax Members (page 160)

AIR is incorporated under the laws of the State of Nevada, and the rights of the AIR stockholders are governed by the NRS, whereas Tenax is organized under the laws of the State of Delaware, and the rights of the Tenax Members are governed by the DLLCA. In addition, AIR stockholders and Tenax Members have different rights pursuant to the governing documents of each of AIR and Tenax. Accordingly, upon the completion of the merger, the Tenax Members will have different rights once they become stockholders of AIR because of the differences between these states of incorporation and formation and the governing documents of AIR and Tenax. See the section entitled “Comparison of Rights of AIR Stockholders and Tenax Members” beginning on page 160 of this proxy statement/prospectus.

No Dissenter’s Rights (page 175)

Pursuant to the NRS, there are no rights of dissent available to the stockholders of AIR in connection with the Transactions.

Material U.S. Federal Income Tax Consequences of the Transactions (page 89)

The Merger

Holders of AIR common stock will not recognize gain or loss for U.S. federal income tax purposes as a result of the merger.

The Redemption Rights

The U.S. federal income tax consequences of the receipt of Redemption Rights by a holder of AIR common stock are unclear. AIR intends to take the position that a holder’s receipt of the Redemption Rights constitutes an “open transaction”. Absent a change in law requiring otherwise after the date of the redemption rights agreement, AIR will not report the issuance of the Redemption Rights as a current distribution to such holder. This position may be challenged by the IRS, in which case a holder could be required to recognize taxable income in respect of the Redemption Rights without the corresponding receipt of cash.

The tax consequences of the Transactions to any particular holder of AIR common stock will depend on that holder’s facts and circumstances. Accordingly, all holders are urged to consult their own tax advisors regarding the tax consequences of the Transactions, including the effects of U.S. federal, state and local laws and non-U.S. tax laws.

Table of Contents

Risk Factors (page 16)

In evaluating the merger agreement and the Transactions, you should carefully read this proxy statement/prospectus and the documents incorporated by reference herein and the annexes attached hereto. In particular, you should consider the factors discussed in the section entitled “Risk Factors” beginning on page 16 of this proxy statement/prospectus. The merger and the businesses of AIR and Tenax involve a number of risks. The following is a summary of some of these risks.

Risks Relating to the Merger

        The closing of the merger is subject to many conditions, and if these conditions are not satisfied or waived, the merger will not be completed.

        There can be no assurance that Tenax will be able to secure the financing necessary to repay AIR’s net senior and subordinated debt in a timely manner or at all.

        If we fail to consummate the merger, we may not be able to operate our business at current levels.

        We and Tenax will be subject to certain operating restrictions until consummation of the merger and business uncertainties until and following the consummation of the merger.

        Existing AIR stockholders will be substantially diluted in the merger and will have significantly reduced relative voting power and influence over AIR following the merger, and the resulting limited public float may adversely affect the liquidity and market price of AIR common stock.

        The merger agreement contains restrictions on our ability to pursue other alternatives to the merger.

        Completion of the merger may require consents or trigger change in control or other provisions in certain agreements to which AIR is a party.

        The unaudited pro forma condensed combined financial statements and prospective financial information included in this proxy statement/prospectus are presented for illustrative purposes only and the actual financial condition and results of operations of the combined company following the merger may differ materially.

        Because there is no public market for Tenax units, the valuation of Tenax is inherently uncertain.

        The Redemption Rights may not provide AIR stockholders with the value or liquidity they may expect in connection with the merger.

Risks Relating to AIR Following the Merger

        The market price for AIR common stock following the merger may be affected by factors different from those that historically have affected AIR common stock.

        Combining AIR and Tenax may be more difficult, costly or time-consuming than expected, and the anticipated benefits and cost savings of the merger may not be realized.

        AIR could lose key personnel or may be unable to recruit qualified personnel following the merger.

        AIR is expected to incur substantial expenses related to the completion of the merger and the integration of AIR and Tenax.

        The future results of AIR may be adversely affected if AIR does not effectively manage its expanded operations following the completion of the merger.

        Following the merger, AIR will meet the requirements to be a “controlled company” and is expected to meet the requirements to be a “Smaller Reporting Company” within the meaning of the rules of the NYSE American and, as a result, will qualify for and, for so long as it so qualifies, intends to rely on exemptions from certain corporate governance standards, which limit the presence of independent directors on its board of directors or board committees and the presence of an independent compensation consultant.

14

Table of Contents

        As a condition to consummation of the merger, unless waived by Tenax, AIR stockholders must approve the written consent proposal, thereby approving an amendment to AIR’s articles of incorporation to include a provision permitting AIR stockholders to act by written consent in lieu of a stockholder meeting under only certain limited circumstances.

        If the combined company fails to comply with the initial or continued listing requirements of the NYSE American, shares of AIR common stock could face possible delisting, which would result in, among other things, a limited public market for shares of AIR common stock and make obtaining future debt or equity financing more difficult for us.

        The issuance of a substantial number of shares of AIR common stock in the merger, and the potential resale of such shares following the merger, may negatively affect the market price of AIR common stock.

        Following the completion of the merger, Thomas Foley will be AIR’s largest stockholder, owning, directly or indirectly, approximately 52% of the fully diluted shares of the AIR common stock, and will have the ability to exercise significant influence over decisions requiring approval of AIR stockholders.

Risks Relating to Tenax’s Business

        Tenax depends on winning profitable business in competitive markets from U.S. government customers for a significant portion of its revenue.

        Tenax derives a significant portion of its revenue from a concentrated number of large contracts, and the loss or material reduction of any of these contracts may adversely affect its business, financial condition, liquidity or results of operations.

        Termination, expiration or non-renewal of Tenax’s existing U.S. government contracts may adversely affect its business.

        A reduction in U.S. government funding, a change in U.S. government spending priorities or a U.S. government shutdown may adversely affect Tenax’s business, financial condition, liquidity or results of operations.

        If Tenax fails to comply with laws and regulations governing federal contractors, Tenax could lose business and be liable for various penalties or sanctions.

        Tenax depends on key personnel at NTC Group, and the loss of these key personnel could adversely affect Tenax’s operations, customer relationships and ability to execute its acquisition strategy.

        Tenax operates in highly competitive markets, and competitive pressures may adversely affect it.

        Tenax’s business could be negatively affected by cyber or other security threats or other disruptions.

        Tenax’s operations depend on its aircraft and hangars, and damage to, or disruption affecting, those assets could materially adversely affect its business, financial condition or results of operations.

        Restrictive and financial covenants in the documents governing Tenax’s existing and any future indebtedness may limit its current and future operations, particularly Tenax’s ability to respond to changes in its business or to pursue its business strategies.

RISK FACTORS

Before you vote, you should carefully consider the risks described in the section entitled “Cautionary Statement Regarding Forward-Looking Statements” beginning on page 32 of this proxy statement/prospectus and the other information contained in this proxy statement/prospectus, particularly the risk factors discussed in this section of this proxy statement/prospectus entitled “Risk Factors”. See the section entitled “Where You Can Find More Information” beginning on page 177 of this proxy statement/prospectus. In addition to the risks set forth below, new risks may emerge from time to time, and it is not possible to predict all risk factors, nor can AIR or Tenax assess the impact of all factors on the merger and AIR following the merger or the extent to which any factor or combination of factors may cause actual results to differ materially from those contained in or implied by any forward-looking statements.

Risks Relating to the Merger

The closing of the merger is subject to many conditions, and if these conditions are not satisfied or waived, the merger will not be completed.

The closing of the merger is subject to a number of conditions as set forth in the merger agreement that must be satisfied or waived, including the effectiveness of the registration statement on Form S-4 of which this proxy statement/prospectus forms a part and the absence of any stop order suspending that effectiveness or proceeding for that purpose, the approval by the AIR stockholders of the stock issuance proposal, the authorized shares proposal and the written consent proposal, the absence of any law or injunction prohibiting the consummation of the merger, the authorization of the listing on the NYSE American of the shares of AIR common stock to be issued in the merger and the receipt of regulatory approvals.

The closing of the merger is also subject to the satisfaction or waiver of a number of other conditions, including, among others, the accuracy of representations and warranties in the merger agreement (subject to certain materiality qualifiers, other customary exceptions and customary cure rights), the performance in all material respects by us and Tenax of our respective obligations under the merger agreement, the absence of a material adverse effect on Tenax or us and the receipt by us and Tenax of officer certificates signed on behalf of Tenax, with respect to the certificate to be received by us, and signed on behalf of us and Merger Sub, with respect to the certificate to be received by Tenax, certifying the satisfaction of the preceding conditions.

For a more complete summary of the conditions that must be satisfied or waived prior to completion of the merger, see the section entitled “The Merger Agreement — Conditions to Completion of the Merger” beginning on page 80 of this proxy statement/prospectus.

There can be no assurance as to whether or when the conditions to the closing of the merger will be satisfied or waived or as to whether or when the merger will be consummated.

There can be no assurance that Tenax will be able to secure the financing necessary to repay AIR’s net senior and subordinated debt in a timely manner or at all.

Although Tenax’s obligation to consummate the merger is not conditioned upon obtaining financing, the merger agreement requires that, at the closing of the merger, Tenax fund the repayment of AIR’s net senior and subordinated debt, amounting in the aggregate to approximately $26.233 million as of May 31, 2026. Tenax relies on loans from a syndicate of banks to fund its operations. As of June 30, 2026, Tenax’s available borrowing capacity under its existing credit facility was $27 million. If Tenax is unable to obtain the necessary lender approvals to increase its borrowing capacity under its existing credit facility to refinance AIR’s net senior and subordinated debt or otherwise obtain commitments from its lenders to satisfy its cash requirements at the closing of the merger, the merger could be delayed or may not be completed. If Tenax were to complete the merger without having sufficient funds to repay AIR’s net senior and subordinated debt, this could reasonably be expected to result in events of default under Tenax’s or AIR’s existing credit agreements, which could have a material adverse effect on the combined company. See the section entitled “The Merger — Financing of the Merger” beginning on page 38 of this proxy statement/prospectus.

The termination of the merger agreement could negatively affect us.

The merger agreement may be terminated at any time prior to the effective time, (i) by mutual written consent of Tenax and AIR, duly authorized by the Tenax Board and the AIR Board, respectively; (ii) by either AIR or Tenax, following a meeting of the AIR stockholders at which the AIR stockholders fail to approve the stock issuance proposal, the authorized shares proposal and the written consent proposal; (iii) by either AIR or Tenax, if any Restraint that has the effect of enjoining, restraining, prohibiting or otherwise preventing the consummation of the Transactions has become final and nonappealable (provided that the party seeking to terminate the merger agreement for this reason has complied in all material respects with its covenants and agreements under the merger agreement regarding the use of efforts to consummate the Transactions); (iv) by either AIR or Tenax, if the effective time has not occurred on or before the Outside Date (provided that the right to terminate the merger agreement for this reason will not be available to (a) any party whose failure to fulfill any obligation under the merger agreement or intentional breach has been a material cause of, or resulted in, the failure of the effective time to occur on or before such time, (b) AIR if any Key AIR Stockholder’s material breach of its obligations under the AIR Stockholder Support Agreement has been a material cause of, or resulted in, the failure of the effective time to occur on or before such time or (c) Tenax if any Tenax Member’s material breach of its obligations under the Tenax Member Support Agreement has been a material cause of, or resulted in, the failure of the effective time to occur on or before such time); (v) by Tenax, upon a breach by either of AIR or Merger Sub of, or a failure by AIR or Merger Sub to perform, any representation, warranty, covenant or agreement set forth in the merger agreement such that the related closing conditions would not be satisfied, and such breach or failure is incapable of being cured by the Outside Date or, if curable by the Outside Date, is not cured within 30 days of receipt by AIR or Merger Sub, as applicable, of written notice of such breach or failure (provided that Tenax will not have the right to terminate the merger agreement pursuant to this clause if Tenax is in material breach of its representations, warranties or covenants at the time of such termination); (vi) by Tenax, if a Change in the AIR Recommendation shall have occurred; (vii) by AIR, upon a breach by Tenax of, or a failure by Tenax to perform, any representation, warranty, covenant or agreement set forth in the merger agreement such that the related closing conditions would not be satisfied, and such breach or failure is incapable of being cured by the Outside Date or, if curable by the Outside Date, is not cured within 30 days of receipt by Tenax of written notice of such breach or failure (provided that AIR will not have the right to terminate the merger agreement pursuant to this clause if AIR is in material breach of its representations, warranties or covenants at the time of such termination); (viii) by AIR, if Tenax fails to close the merger within three business days after all closing conditions have been satisfied or waived or AIR’s delivery of a written notice to Tenax that all of Tenax’s closing conditions have been satisfied or waived or that AIR is willing to waive any unsatisfied conditions; or (ix) by AIR, to accept a Superior Proposal.

If the merger agreement is terminated for any reason, our ongoing business may be adversely affected and, without realizing any of the anticipated benefits of having completed the Transactions, we would be subject to a number of risks, including the following:

        the market price of AIR common stock could decline;

        if the merger agreement is terminated and the AIR Board seeks another business combination, our stockholders cannot be certain that we will be able to find a party willing to enter into a transaction on terms equivalent to or more attractive than the terms that Tenax has agreed to in the merger agreement;

        time and resources, financial and other, committed by our management to matters relating to the Transactions could otherwise have been devoted to pursuing other beneficial opportunities for our company;

        we may experience negative reactions from the financial markets or from our customers, suppliers or employees; and

        we may be required to pay our respective costs relating to the Transactions, including legal, accounting, financial advisory, financing and printing fees, whether or not the Transactions are completed.

If the merger agreement is terminated, under specified circumstances, we may be required to pay Tenax a termination fee of $1.25 million. See the section entitled “The Merger Agreement — Expenses and Termination Fees” beginning on page 82 of this proxy statement/prospectus for a more complete discussion of the circumstances under which the merger agreement could be terminated.

17

Table of Contents

In addition, if the merger is not completed, we could be subject to litigation related to any failure to complete the merger or related to any enforcement proceeding commenced against us to perform our obligations under the merger agreement. The materialization of any of these risks could materially and adversely affect our ongoing business.

If we fail to consummate the merger, we may not be able to operate our business at current levels.

Unless the merger is consummated, we may not be able to continue to operate our business at current levels unless we are able to generate substantial revenues and become profitable and/or obtain substantial additional financing from a conventional bank lender or other financial institution to replace our existing credit facility with Webster Bank upon its termination at September 30, 2026, and our obligations under the subordinated debt, or refinance such indebtedness on terms acceptable to us or through the issuance of our debt and/or equity securities. There can be no assurance that AIR would be able to obtain such financing or refinancing on acceptable terms or at all, or that AIR would be able to generate sufficient revenues to service its existing indebtedness and fund its operations on a standalone basis.

We and Tenax will be subject to certain operating restrictions until consummation of the merger and business uncertainties until and following the consummation of the merger.

Uncertainty about the effect of the merger on employees and customers may have an adverse effect on us, Tenax or the combined company following the merger. These uncertainties could disrupt our business or the business of Tenax and cause customers, suppliers, vendors, partners and others that deal with us and Tenax to defer entering into contracts with us and Tenax or making other decisions concerning us and Tenax or seek to change or cancel existing business relationships with us and Tenax. Retention and motivation of certain employees may be challenging during the pendency of the merger due to uncertainty about their future roles and difficulty of integration. If key employees depart because of issues related to the uncertainty and difficulty of integration or a desire not to remain with AIR following the merger, AIR’s business following the merger could be negatively affected. In addition, the merger agreement restricts AIR and Tenax from making certain acquisitions and investments and imposes certain other restrictions on the conduct of each party’s business until the merger occurs without the consent of the other party. These restrictions may negatively affect each party’s business and operations or prevent either party from pursuing attractive business opportunities that may arise prior to the completion of the merger which may reduce the profitability of AIR following the merger. See the sections entitled “The Merger Agreement — Other Covenants and Agreements — Conduct of Business of AIR Prior to Completion of the Merger” beginning on page 69 of this proxy statement/prospectus and “The Merger Agreement — Other Covenants and Agreements — Conduct of Business of Tenax Prior to Completion of the Merger” beginning on page 72 of this proxy statement/prospectus for descriptions of the restrictive covenants to which each of AIR and Tenax is subject.

Existing AIR stockholders will be substantially diluted in the merger and will have significantly reduced relative voting power and influence over AIR following the merger, and the resulting limited public float may adversely affect the liquidity and market price of AIR common stock.

If the merger is completed, the existing AIR stockholders as of immediately prior to the effective time will collectively own approximately 4% of the outstanding shares of AIR common stock, on a fully diluted basis, and the Tenax Members and Tenax Warrantholders will collectively own approximately 96% of the outstanding shares of AIR common stock, on a fully diluted basis. As a result, existing AIR stockholders will experience substantial dilution and will own only a minority interest in AIR following the merger.

In addition, following the consummation of the merger, the composition of the AIR Board will change significantly. The AIR Board will consist of no fewer than eight directors, of which no fewer than six will be designated by Tenax and two of which will be mutually agreed upon by Tenax and AIR. As a result, existing AIR stockholders will have significantly less influence over the management, business, operations, strategy and policies of AIR following the merger than they currently have.

This significant reduction in relative ownership and voting power may cause existing AIR stockholders to have interests that differ from those of the Tenax Members and may limit the ability of existing AIR stockholders to influence significant corporate decisions following the merger.

Table of Contents

Although the amended and restated merger agreement will help facilitate the satisfaction of the NYSE American minimum listing requirement related to public float, AIR’s unrestricted public float held by non-insiders (as determined for purposes of determining compliance with the NYSE American’s listing requirements) is expected to represent less than one-quarter of the outstanding shares of AIR common stock following the merger. Such limited public float may adversely affect the liquidity and trading price of AIR common stock, AIR’s ability to satisfy NYSE American continued listing requirements and AIR’s ability to raise capital in the public markets or attract institutional investor interest in the combined company.

The merger agreement contains restrictions on our ability to pursue other alternatives to the merger.

The merger agreement contains non-solicitation provisions that, subject to limited exceptions, restrict our and our subsidiaries’ ability to, directly or indirectly, initiate, solicit, encourage, induce or assist any inquiries or the making, submission, announcement or consummation of, proposals or offers that constitute or could reasonably be expected to lead to any Competing AIR Proposal. Further, subject to limited exceptions, consistent with applicable law, the merger agreement provides that the AIR Board will not withhold, withdraw, qualify or modify (or publicly propose or resolve to withhold, withdraw, qualify or modify) in a manner adverse to Tenax its recommendation that the AIR stockholders vote in favor of the stock issuance proposal, the authorized shares proposal and the written consent proposal. Although the AIR Board is permitted to take certain actions in response to a Superior Proposal or an Intervening Event if (subject to compliance with the provisions of the merger agreement) it determines in good faith (after consultation with AIR’s outside legal counsel) that the failure to do so would reasonably be expected to violate its fiduciary duties under applicable law, doing so in specified situations could require us to pay to Tenax a termination fee of $1.25 million. See the sections entitled “The Merger Agreement — Other Covenants and Agreements — No Solicitation by AIR”, “The Merger Agreement — Other Covenants and Agreements — Change in the AIR Recommendation” and “The Merger Agreement — Expenses and Termination Fees” beginning on pages 73, 74 and 82, respectively, of this proxy statement/prospectus for a more complete discussion of these restrictions and consequences.

Such provisions could discourage a potential acquiror that might have an interest in making a proposal from considering or proposing any such transaction. There also is a risk that the requirement to pay the AIR Termination Fee or expense reimbursement payment to Tenax in certain circumstances may result in a potential acquiror proposing to pay a lower per share price to acquire us than it might otherwise have proposed to pay.

Completion of the merger may require consents or trigger change in control or other provisions in certain agreements to which AIR is a party.

The completion of the Transactions may require consents or trigger change in control or other provisions in certain agreements to which AIR is a party. If Tenax and AIR are unable to obtain consents or negotiate waivers of those provisions, the counterparties may exercise their rights and remedies under the agreements, potentially terminating the agreements, discontinuing business relationships or seeking monetary damages. Even if Tenax and AIR are able to obtain consents or negotiate waivers, the counterparties may require a fee for such waivers or seek to renegotiate the agreements on terms less favorable to AIR. Such action could cause AIR to lose business, increase the cost of doing business and/or lower profitability or have other adverse financial impacts.

The unaudited pro forma condensed combined financial statements and prospective financial information included in this proxy statement/prospectus are presented for illustrative purposes only and the actual financial condition and results of operations of the combined company following the merger may differ materially.

The unaudited pro forma condensed combined financial statements and prospective financial information contained in this proxy statement/prospectus are presented for illustrative purposes only; are based on various adjustments, assumptions and preliminary estimates; and do not represent the actual financial condition or results of operations of AIR and Tenax prior to the merger and may not be an indication of financial condition or results of operations of the combined company following the merger for several reasons. The actual financial condition and results of operations of AIR and Tenax prior to the merger and those of the combined company following the merger may not be consistent with, or evident from, these unaudited pro forma condensed combined financial statements and prospective financial information. In addition, the assumptions used in preparing the unaudited pro forma condensed combined financial statements and prospective financial information may not be realized, and other factors may affect AIR’s and Tenax’s respective financial condition or results of operations prior to the merger and the combined company’s financial condition or results of operations following the merger. Furthermore,

19

Table of Contents

following the merger, AIR will conduct a review of its accounting policies in an effort to determine if differences in accounting policies require restatement or reclassification of results of operations or reclassification of assets or liabilities to conform to Tenax’s accounting policies and classifications. As a result of that review, the combined company may identify differences among the accounting policies of the companies that, when conformed, could have a material impact on the unaudited pro forma condensed combined financial statements contained in this proxy statement/prospectus. Any potential decline in AIR’s, Tenax’s or the combined company’s financial condition or results of operations may cause significant variations in the pro forma financial statements and AIR’s stock price following the closing of the merger.

We may waive one or more of the conditions to the merger without resoliciting stockholder approval.

We may determine to waive, in whole or in part, one or more of the conditions to our obligations to complete the merger, to the extent permitted by applicable laws. We will evaluate the materiality of any such waiver and its effect on the AIR stockholders in light of the facts and circumstances at the time to determine whether any amendment of this proxy statement/prospectus and resolicitation of proxies is required or warranted. In some cases, if the AIR Board determines that such a waiver is warranted but that such waiver or its effect on the AIR stockholders is not sufficiently material to warrant resolicitation of proxies, we have the discretion to complete the merger without seeking further stockholder approval. Any determination whether to waive any condition to the merger or as to resoliciting stockholder approval or amending this proxy statement/prospectus as a result of a waiver will be made by us at the time of such waiver based on the facts and circumstances as they exist at that time.

If our due diligence investigation of Tenax was inadequate or if unexpected risks related to Tenax’s business materialize, it could have a material adverse effect on our stockholders’ investment.

Even though we conducted a due diligence investigation of Tenax, we cannot be sure that our diligence surfaced all material issues that may be present inside Tenax or its business, or that it would be possible to uncover all material issues through a customary amount of due diligence, or that factors outside of Tenax and its business and outside of its control will not arise later. If any such material issues arise, they may materially and adversely affect the ongoing business of AIR and our stockholders’ investment.

Because there is no public market for Tenax units, the valuation of Tenax is inherently uncertain.

The outstanding membership interests of Tenax are privately held and are not traded in any public market. As a result, the value of Tenax is inherently uncertain and difficult to determine. Because Tenax units are not publicly traded and there is no established market price for Tenax, the value of the shares of AIR common stock to be issued to the Tenax Members as the merger consideration may ultimately be greater than or less than the value that might be ascribed to Tenax in a public market as of the effective time. As a result, the merger consideration may not reflect the value that investors or analysts might independently assign to Tenax.

The Redemption Rights may not provide AIR stockholders with the value or liquidity they may expect in connection with the merger.

AIR stockholders will not receive merger consideration directly in the merger. Instead, AIR has agreed to, prior to the closing, issue Redemption Rights that may become exercisable on the first anniversary of the closing under specified conditions. This arrangement is subject to significant limitations, including timing conditions and price-based triggers. Accordingly, AIR stockholders may not be able to realize value through the Redemption Rights, or may do so only on a delayed basis, and the Redemption Rights may not fully offset the dilution resulting from the merger.

Risks Relating to AIR Following the Merger

The market price for AIR common stock following the merger may be affected by factors different from those that historically have affected AIR common stock.

Following the merger, AIR’s business will include operations of Tenax that differ from AIR’s operations prior to the merger, and accordingly the results of operations of AIR following the merger will be affected by some factors that are different from those currently affecting our results of operations. This proxy statement/prospectus describes the business of Tenax and also describes important factors to consider in connection with that business and the business of AIR following the merger. For a discussion of these matters, see, for example, the sections

20

Table of Contents

entitled “Description of Tenax Business”, “Management’s Discussion and Analysis of Financial Condition and Results of Operations of Tenax” and “Unaudited Pro Forma Condensed Combined Financial Information” beginning on pages 123, 131 and 93, respectively, in this proxy statement/prospectus.

Combining AIR and Tenax may be more difficult, costly or time-consuming than expected, and the anticipated benefits and cost savings of the merger may not be realized.

We and Tenax have operated and, until the completion of the merger, will continue to operate independently. The success of the merger, including anticipated benefits and cost savings, will depend, in part, on our ability to successfully combine and integrate our business with the business of Tenax.

The merger will involve the integration of Tenax’s business with our existing business, which is a complex, costly and time-consuming process. It is possible that the pendency of the merger and/or the integration process could result in material challenges, including, without limitation:

        the diversion of management’s attention from ongoing business concerns and performance shortfalls at one or both of the companies as a result of the devotion of management’s attention to the merger;

        managing a larger combined company;

        the transition of management from AIR’s executive management team to Tenax’s executive management team;

        maintaining employee morale and retaining key management and other employees;

        the possibility of faulty assumptions underlying expectations regarding the integration process;

        retaining existing business and operational relationships and attracting new business and operational relationships;

        consolidating corporate and administrative infrastructures and eliminating duplicative operations and inconsistencies in standards, controls, procedures and policies;

        integrating the companies’ financial reporting and internal control systems, including compliance by the combined company with Section 404 of the Sarbanes-Oxley Act of 2002, as amended, and the rules promulgated thereunder by the SEC;

        adapting Tenax’s management team and operational infrastructure to the reporting, disclosure and governance obligations applicable to SEC reporting companies, including under the Exchange Act, the Sarbanes-Oxley Act and the NYSE American listing requirements, to which Tenax has not previously been subject;

        remediating AIR’s existing material weakness in internal controls over financial reporting, which has remained unremediated since 2022, while simultaneously integrating Tenax’s financial reporting and control systems, which have not previously been subject to the requirements applicable to SEC reporting companies;

        coordinating geographically separate organizations;

        maintaining and protecting the competitive advantages of each of AIR and Tenax, including the trade secrets, know-how and intellectual property related to their respective production processes;

        unanticipated issues in integrating information technology, communications and other systems; and

        unforeseen expenses or delays associated with the merger.

Many of these factors will be outside of the combined company’s control, and any one of them could result in delays, increased costs, decreases in revenues and diversion of management’s time and energy, which could materially affect the combined company’s financial position, results of operations and cash flows following the merger.

21

Table of Contents

If we or Tenax experience difficulties with the integration process, the anticipated benefits of the merger may not be realized fully or at all, or may take longer to realize than expected. These integration matters could have an adverse effect on (i) each of AIR and Tenax during this transition period and (ii) the combined company for an undetermined period after completion of the merger. In addition, the actual cost savings of the merger could be less than anticipated.

AIR could lose key personnel or may be unable to recruit qualified personnel following the merger.

AIR’s future success depends upon the continued contributions of our senior management and other key personnel and the ability to retain and motivate them. If we are unable to retain and motivate the senior management team and other key personnel sufficiently to maintain our current business and, following the merger, support the projected growth and initiatives of the combined business, our respective business and financial performance may be adversely affected.

The future results of AIR may be adversely affected if AIR does not effectively manage its expanded operations following the completion of the merger.

Following the completion of the merger, the size of AIR’s business will be significantly larger than the current size of either our or Tenax’s respective businesses. AIR’s ability to successfully manage this expanded business will depend, in part, upon management’s ability to design and implement strategic initiatives that address not only the integration of two discrete companies, but also the increased scale and scope of the combined business with its associated increased costs and complexity. There can be no assurances that the combined company will be successful or that it will realize the expected operating efficiencies, cost savings and other benefits currently anticipated from the merger.

AIR is expected to incur substantial expenses related to the completion of the merger and the integration of AIR and Tenax.

We and Tenax have incurred, and expect to continue to incur, a number of nonrecurring costs associated with the merger and combining the operations of the two companies. The substantial majority of nonrecurring expenses will be composed of transaction and regulatory costs related to the merger. AIR also will incur transaction fees and costs related to formulating and implementing integration plans, including facilities and systems consolidation costs and employment-related costs. We and Tenax continue to assess the magnitude of these costs, and additional unanticipated costs may be incurred in the merger and the integration of the two companies’ businesses.

Following the merger, the composition of the AIR Board will be different than the composition of the current AIR Board.

Upon consummation of the merger, the composition of the AIR Board will be different than the current AIR Board. The AIR Board currently consists of six directors. Upon the consummation of the merger, the AIR Board will consist of no fewer than eight directors:

        no fewer than six individuals will be designated by Tenax; and

        two individuals will be mutually agreed upon by Tenax and AIR.

This new composition of AIR Board may affect the future decisions of AIR.

Following the merger, AIR will meet the requirements to be a “controlled company” within the meaning of the rules of the NYSE American and, as a result, will qualify for and, for so long as it so qualifies, intends to rely on exemptions from certain corporate governance standards, which limit the presence of independent directors on its board of directors or board committees.

Following the merger, approximately 96% of the outstanding shares of AIR common stock will be held by the Tenax Members and Tenax Warrantholders, on a fully diluted basis, and approximately 4% will be held by the current AIR stockholders, on a fully diluted basis. Thomas Foley will own, directly or indirectly, approximately 52% of the fully diluted shares of AIR common stock.

22

Table of Contents

As a result, AIR will be a “controlled company” for purposes of Section 801(a) of the NYSE American Company Guide and will be exempt from certain governance requirements otherwise required by the NYSE American. Under Section 801(a), a company in which over 50% of the voting power is held by an individual, a group or another company is a “controlled company” and is exempt from certain corporate governance requirements, including requirements that (1) a majority of AIR’s board of directors consist of independent directors, (2) director nominees be selected or recommended for selection by a majority of the independent directors or by a nominating committee composed solely of independent directors and (3) compensation of the chief executive officer be determined or recommended to the board of directors by a majority of its independent directors or by a compensation committee composed of independent directors. Following the consummation of the merger, AIR will continue to have an Audit Committee that is composed entirely of independent directors.

As a result, the procedures for approving significant corporate decisions could be determined by directors who have a direct or indirect interest in such decisions, and the AIR stockholders will not have the same protections afforded to stockholders of other companies that are required to comply with the independence rules of the NYSE American.

Following the merger, AIR is expected to meet the requirements to be a “Smaller Reporting Company” within the meaning of the rules of the NYSE American and, as a result, is expected to qualify for and, if and for so long as it so qualifies, intends to rely on exemptions from certain corporate governance standards, which limit the presence of independent directors on its board of directors or board committees and the presence of an independent compensation consultant.

AIR is expected to qualify as a “Smaller Reporting Company” for purposes of Section 801(h) of the NYSE American Company Guide and will be exempt from certain governance requirements otherwise required by the NYSE American. Under Section 801(h), a company that satisfies the definition of smaller reporting company in Rule 12b-2 of the Exchange Act, meaning it is an issuer that is not an investment company, an asset-backed issuer or a majority-owned subsidiary of a parent that is not a smaller reporting company and that (1) has a public float of less than $250 million or (2) has annual revenues of less than $100 million and either (i) no public float or (ii) a public float of less than $700 million, is a “Smaller Reporting Company”. Smaller Reporting Companies are only required to maintain a board of directors composed of at least 50% independent directors (rather than a majority of independent directors) and an audit committee of at least two independent members (rather than three independent members). In addition, Smaller Reporting Companies are not subject to the same independence requirements for the compensation committee and compensation consultants.

As a result, the procedures for approving significant corporate decisions could be determined by directors who have a direct or indirect interest in such decisions, and the AIR stockholders will not have the same protections afforded to stockholders of other companies that are required to comply with the independence rules of the NYSE American.

As a condition to consummation of the merger, unless waived by Tenax, AIR stockholders must adopt a provision permitting AIR stockholders to act by written consent in lieu of a stockholder meeting under only certain limited circumstances.

Under AIR’s existing articles of incorporation and bylaws, AIR stockholders are currently not permitted to take stockholder action by written consent in lieu of a stockholder meeting. As a condition to completion of the merger, unless waived by Tenax, the AIR stockholders must approve the written consent proposal, thereby approving an amendment to AIR’s articles of incorporation to authorize stockholder action by written consent in lieu of a stockholder meeting at any time while NTC Group, Thomas Foley and Taran Bakker and their respective affiliates collectively beneficially own at least a majority of the voting power of the outstanding shares of AIR common stock. At any time when NTC Group, Thomas Foley and Taran Bakker and their respective affiliates collectively do not beneficially own at least a majority of the voting power of the outstanding shares of AIR common stock, any action required to be taken or permitted to be taken by stockholders of AIR may be effected only at a duly called annual or special meeting of stockholders and may not be taken by written consent. A reinstatement of a prohibition on stockholder action by written consent at any time when NTC Group, Thomas Foley and Taran Bakker and their respective affiliates no longer collectively beneficially own at least a majority of the voting power of the outstanding shares of AIR common stock may be considered an anti-takeover measure by forcing a potential acquirer to take control of AIR only at a duly called special or annual meeting.

Table of Contents

If the combined company fails to comply with the initial listing requirements of the NYSE American, shares of AIR common stock could face possible delisting, which would result in, among other things, a limited public market for shares of AIR common stock and make obtaining future debt or equity financing more difficult for us.

Under Section 341 of the NYSE American Company Guide, if a listed issuer engages in a reverse merger, it will be eligible for continued listing on the NYSE American only if the post-transaction entity meets the standards for initial listing. Companies listed on the NYSE American are subject to initial listing standards that require, among other things, a minimum share price of $4.00 per share and an aggregate market value of unrestricted publicly held shares of at least $15 million. As of the date of this proxy statement/prospectus, the trading price of AIR’s common stock on the NYSE American is less than $4.00 per share, and there is no assurance that it will not be below $4.00 per share at the effective time, meaning the combined company would fail to meet the standards for initial listing on the NYSE American.

Assuming the authorized shares proposal is approved at the special meeting and after the related amendment to the articles of incorporation of AIR becomes effective, AIR intends to effect the reverse stock split prior to the closing of the merger in order to satisfy the $4.00 minimum share price requirement for initial listing on the NYSE American under Section 101 of the NYSE American Company Guide. While the reverse stock split is intended to increase the per share price of AIR common stock above the $4.00 threshold, there can be no assurance that the market price of AIR common stock will be at or above $4.00, at the closing of the merger or for any sustained period thereafter. The market price of AIR common stock and the resulting market value of unrestricted publicly held shares depends on many factors unrelated to the number of shares outstanding, including our operating results, financial condition, prospects and general market and economic conditions. Additionally, reverse stock splits are often viewed negatively by investors and may result in reduced trading volume and liquidity in AIR common stock.

If AIR common stock fails to satisfy the NYSE American initial listing requirements (or, subsequent to the merger, the continued listing requirements), AIR common stock could be delisted from the NYSE American. If AIR common stock is delisted, it would likely trade on the over-the-counter market, which could significantly reduce the liquidity and market price of AIR common stock, limit the combined company’s ability to raise additional capital through equity issuances, result in a loss of confidence by investors, employees and business partners and make AIR common stock subject to “penny stock” rules, which would impose additional burdens on broker-dealers and further restrict secondary market trading in AIR common stock. Any such delisting could have a material adverse effect on the combined company’s business, financial condition and results of operations.

The issuance of a substantial number of shares of AIR common stock in the merger, and the potential resale of such shares following the merger, may negatively affect the market price of AIR common stock.

In the merger, AIR will issue a substantial number of shares of AIR common stock to the Tenax Members, who, combined with the Tenax Warrantholders, are expected to own approximately 96% of the outstanding shares of AIR common stock following the merger, on a fully diluted basis. In addition, the registration rights agreement will grant certain Tenax Members demand registration rights for the resale of shares of AIR common stock held by them. See the section entitled “Other Related Agreements — Registration Rights Agreement” beginning on page 12 of this proxy statement/prospectus. The market price of AIR common stock could decline as a result of sales of a large number of shares of AIR common stock in the market after the exercise of such registration rights, or even the perception that these sales could occur.

Following the completion of the merger, Thomas Foley will be AIR’s largest stockholder, owning, directly or indirectly, approximately 52% of the fully diluted shares of the AIR common stock, and will have the ability to exercise significant influence over decisions requiring the AIR stockholders’ approval.

AIR will be controlled by Thomas Foley following the completion of the merger. Mr. Foley will own, directly or indirectly, approximately 52% of the fully diluted shares of the AIR common stock. As a result, Mr. Foley will have the ability to exercise significant influence over decisions requiring approval of the AIR stockholders, including the election of directors, amendments to AIR’s articles of incorporation and approval of significant corporate transactions, such as a merger or other sale of AIR or its assets.

This concentration of ownership may have the effect of delaying, preventing or deterring a change in control of AIR and may negatively affect the market price of AIR’s common stock. Also, Thomas Foley and his affiliated entities are in the business of making investments in companies and may from time to time acquire and hold interests in businesses that compete with AIR. Mr. Foley or his affiliates may also pursue acquisition opportunities that are complementary to AIR’s business and, as a result, those acquisition opportunities may not be available to AIR.

Risks Relating to Tenax’s Business

Tenax depends on winning profitable business in competitive markets from U.S. government customers for a significant portion of its revenue.

Tenax derives a substantial portion of its revenue from contracts with the U.S. government, the most significant of which are typically awarded through a rigorous competitive bidding process. This competitive bidding process presents several risks, including the following:

        Tenax may bid on programs for which the work activities, deliverables and timelines are vague or for which the solicitation incompletely describes the actual work, which may result in inaccurate pricing assumptions;

        Tenax may incur substantial costs and spend a significant amount of managerial time and effort preparing bids and proposals with no guarantee of winning new business; and

        Tenax may realize the lost opportunity cost of not bidding on and winning other contracts that it may have pursued otherwise.

Reductions in the number and amounts of new awards, delays in the timing of anticipated awards or potential cancellations of such awards as a result of government appropriations or funding priorities, economic conditions, geopolitical pressures, material and equipment pricing and availability or other factors could adversely affect Tenax’s long-term financial results.

Following contract award, Tenax may also encounter significant expense associated with transitioning to a new contract, delay, contract modifications or the contract may be protested. Any project delays, cancellations, contract modifications or protests may adversely affect its business, financial condition, liquidity or results of operations.

In addition, Tenax faces rigorous competition and pricing pressures for any additional contract awards from the U.S. government. Many of Tenax’s existing contracts must be recompeted when the original period of performance ends. Recompetes represent opportunities for competitors to take business away from Tenax. Recompetes also represent opportunities for Tenax’s customers to obtain more favorable terms from Tenax that may present finance and performance risk. Tenax may be required to qualify or continue to qualify under multiple award contracts, and it may be more difficult for Tenax to pursue or win future task orders. If Tenax is unable to consistently win new contract awards, or successfully win recompetes for its existing contracts, Tenax’s business and prospects will be adversely affected, and its actual results may differ materially and adversely from those anticipated.

Tenax derives a significant portion of its revenue from a concentrated number of large contracts, and the loss or material reduction of any of these contracts may adversely affect its business, financial condition, liquidity or results of operations.

Tenax derives a significant portion of its revenues from the U.S. Forest Service Aerial Supervision Module program, the U.S. Army Geospatial Center’s HR3D program and the U.S. Navy Contracted Air Services Stand Off Jamming program. The loss of any of these contracts, significant changes in the prices or other important terms provided under any of these contracts or adverse developments with respect to these customers’ funding could materially reduce Tenax’s revenue, results of operations and cash flows.

Termination, expiration or non-renewal of Tenax’s existing U.S. government contracts may adversely affect its business.

Tenax’s U.S. government contracts generally are of a finite duration. The termination, expiration or non-renewal of Tenax’s existing U.S. government contracts could result in a loss of anticipated future revenue, which may adversely affect its business, financial condition, liquidity or results of operations.

25

Table of Contents

The U.S. government may stop work or terminate any of Tenax’s government contracts, in whole or in part, at any time at its convenience with little or no notice in accordance with federal acquisition regulations. In addition, for some of its contracts, Tenax is a subcontractor and not the prime contractor, and in those arrangements, the U.S. government could terminate the prime contractor for convenience without regard for Tenax’s performance as a subcontractor. Tenax can give no assurance that one or more of its U.S. government contracts will not be terminated under such circumstances.

The U.S. government may also terminate Tenax’s contracts for default if Tenax fails to meet its obligations under a contract. If any of Tenax’s contracts were terminated for convenience, Tenax generally would be entitled to receive payment for work completed and allowable termination or cancellation costs incurred on or prior to the termination effective date. If any of Tenax’s government contracts were terminated for default, generally the customer would pay Tenax only for the work that has been accepted. Moreover, the customer can require Tenax to pay the difference between the original contract price and the cost to re-procure the contract deliverables, net of the work accepted from the original contract. In addition, the U.S. government can also hold Tenax liable for damages resulting from the default.

The expiration, non-renewal or early termination of any government contracts, whether for convenience or default, would adversely affect Tenax’s current programs and reduce its revenue, earnings and cash flows. A termination for default may also negatively affect Tenax’s reputation, performance ratings and ability to win new government contracts, particularly for contracts covering the same or similar types of services, affect Tenax’s ability to receive extensions on current contracts and complete the full period of performance of such contracts and may lead to increased litigation costs associated with challenging such early termination.

A reduction in U.S. government funding, a change in U.S. government spending priorities or a U.S. government shutdown may adversely affect Tenax’s business, financial condition, liquidity or results of operations.

Tenax’s contracts and revenue greatly depend upon the budgets of certain departments and agencies of the U.S. government, which are subject to the congressional budget authorization and appropriations process and are difficult to predict. The U.S. Congress usually appropriates funds for a given program on an October 1 to September 30 fiscal year basis. Most of Tenax’s U.S. government contracts, whether directly held or subcontracted through a prime contractor, are funded with operation and management (“O&M”) funds, which can only be committed for the current fiscal year. As a result, most of Tenax’s U.S. government contracts have a one-year base period and two to four option years. Funding for the option years is not guaranteed and must be appropriated by the U.S. Congress in future fiscal years. Impacts on the budgets of certain departments and agencies of the U.S. government are a function of many factors beyond Tenax’s control, including, but not limited to, changes in U.S. procurement policies, budget considerations, the federal debt ceiling, current and future economic conditions, presidential administration and congressional priorities, continuing resolutions, changing national security and defense requirements, geopolitical developments and actual fiscal year congressional appropriations for defense budgets. Any of these factors could result in a significant redirection of current and future budgets of certain departments and agencies of the U.S. government and affect Tenax’s future operations and cash flows. Such factors may have a direct bearing on Tenax’s new business opportunities as well as on whether the U.S. government will exercise its options for services under existing contracts, thus affecting the timing and volume of Tenax’s business.

Tenax has also faced, and may in the future face, a prolonged government shutdown, such as the 2025 U.S. federal government shutdown. A prolonged government shutdown could limit Tenax’s ability to be awarded new work, receive additional orders on current contracts, win recompetes or be paid under current contracts.

If Tenax fails to comply with laws and regulations governing federal contractors, Tenax could lose business and be liable for various penalties or sanctions.

Tenax must comply with laws and regulations relating to the formation, administration and performance of government contracts. These laws and regulations include the Federal Acquisition Regulations (“FAR”), Defense Federal Acquisition Regulations, the Truth in Negotiations Act, the Procurement Integrity Act, the Civil False Claims Act, Cost Accounting Standards and laws, regulations and orders restricting the use and dissemination of classified information under the U.S. export control laws and the export of certain products and technical information and

26

Table of Contents

safeguarding of contractor information systems. Substantive policy and enforcement priorities related to government contracts are changing very quickly and sometimes ambiguously, adding to the risk. For example, FAR is currently under a comprehensive review and re-write, which may affect Tenax’s business and overall risk once implemented.

In addition, Tenax is subject to U.S. government inquiries and investigations, including periodic audits of costs that Tenax determines are reimbursable under government contracts. U.S. government agencies routinely audit government contractors, including Tenax, to review performance under contracts, cost structure, compliance with applicable contracting and procurement laws, regulations and standards and compliance with applicable cybersecurity requirements, as well as the adequacy of and compliance with internal control systems and policies, including the contractor’s purchasing, property, estimating, compensation and management information systems. Any costs found to be misclassified, inaccurately allocated to a specific contract or otherwise unallowable are not reimbursable and, to the extent already reimbursed, must be refunded. If an audit uncovers improper or illegal activities, Tenax could be subject to possible civil and criminal penalties, sanctions or suspension or debarment. Whether or not illegal activities are alleged, the U.S. government has the ability to decrease or withhold certain payments when it deems systems to be inadequate, with significant financial impact, regardless of the ultimate outcome. As a result of such actions, Tenax may be subject to increased scrutiny, identified for enforcement action or required to engage in remediation efforts, any or all of which could damage Tenax’s reputation, increase its costs (including compliance costs) and risks, create operational challenges or adversely affect its competitiveness. In addition, Tenax risks serious reputational harm in situations involving allegations of impropriety made against Tenax or Tenax’s business partners. Finally, any inadequacies in Tenax’s systems and policies could result in termination of a contract, forfeiture of profits, suspension of payments, fines or suspension or debarment from U.S. government contracting or subcontracting for a period of time.

In addition, facility and personnel security clearances are required in order to be awarded and be able to perform on certain contracts for the U.S. government, which are a significant part of Tenax’s business. Tenax has obtained clearances at appropriate levels that require stringent qualifications, and Tenax may be required to seek higher-level clearances in the future. If for some reason Tenax’s security clearances are invalidated or terminated, Tenax may not be able to continue to perform under some of its contracts or be able to enter into new contracts requiring security clearances, which could affect its ability to maintain current business and to compete for and win new business.

Tenax’s industry is heavily regulated, and if Tenax fails to comply with applicable requirements, its results of operations could suffer.

Tenax’s industry is highly regulated by multiple regulatory authorities within the U.S. government. Before Tenax makes modifications to any airframes, they must meet certain standards of airworthiness established by these regulatory authorities. New and more stringent governmental regulations may be adopted in the future that, if enacted, may have an adverse impact on Tenax. If any of Tenax’s material licenses, certificates, authorizations or approvals were revoked or suspended, its business, financial condition, liquidity and results of operations may be adversely affected.

Violations of applicable laws or regulations by Tenax or by those with whom or through whom Tenax does business could subject Tenax to administrative, civil or criminal investigations and monetary and non-monetary penalties, including suspension and debarment, which could negatively affect its reputation and ability to conduct business and may adversely affect its business, financial condition, liquidity or results of operations.

Tenax’s reputation, ability to do business and financial condition, liquidity and/or results of operations may be affected by the improper conduct of its employees, agents, suppliers, subcontractors or partners.

Misconduct, fraud or other improper activities by Tenax’s employees, agents, suppliers, subcontractors or business partners could have a material adverse impact on its business and reputation. Such misconduct could include the failure to comply with federal, state, local or foreign government procurement regulations, regulations regarding the protection of classified or personal information, legislation regarding the pricing of labor and other costs in government contracts, regulations pertaining to the internal controls over financial reporting, laws and regulations relating to environmental matters, bribery of foreign government officials, lobbying or similar activities, boycotts, antitrust and any other applicable laws or regulations. In addition, misconduct involving data security lapses or inadequate cybersecurity protections resulting in the compromise of personal information or the improper

27

Table of Contents

use of Tenax’s customers’ sensitive or classified information could result in remediation costs, regulatory sanctions against Tenax and serious harm to its reputation. Although Tenax has implemented internal policies, procedures, controls and training that are designed to prevent and detect these activities, these precautions may not prevent all misconduct and, as a result, Tenax could face unknown risks or losses. Misconduct by any of Tenax’s employees, agents, suppliers, subcontractors or business partners or Tenax’s failure to comply with applicable laws or regulations or with applicable internal policies, procedures and controls could create a deficiency in internal controls over financial reporting, subject Tenax to fines and penalties, loss of security clearance, loss of current and future customer contracts and suspension or debarment from contracting with federal, state or local government agencies, any of which may adversely affect its business, financial condition, liquidity or results of operations.

Tenax depends on key personnel at NTC Group, and the loss of these key personnel could adversely affect Tenax’s operations, customer relationships and ability to execute its acquisition strategy.

Thomas Foley and Taran Bakker are majority owners of Tenax and are actively engaged in overseeing Tenax’s operations, including making important decisions regarding contract pricing, hiring, capital expenditures, refinancings and strategy. Mr. Foley and Mr. Bakker also maintain networks of relationships in the aerospace and defense industry and among Tenax’s customers that are important to Tenax’s ability to maintain and grow its business.

Mr. Foley and Mr. Bakker are also responsible for directing Tenax’s acquisition strategy and efforts to identify and evaluate potential acquisitions. Tenax has limited internal personnel with the experience necessary to independently source, negotiate and execute acquisitions without the involvement of Mr. Foley and Mr. Bakker.

If either Mr. Foley or Mr. Bakker ceased to be involved at Tenax, Tenax may be unable to replace their expertise, industry knowledge and relationships on a timely basis or at all, which could disrupt Tenax’s operations, harm Tenax’s business and customer relationships, impair Tenax’s ability to secure new contracts and execute acquisitions and adversely affect Tenax’s business, financial condition, liquidity or results of operations.

Supply chain disruptions could have adverse effects on Tenax’s ability to provide certain products and services.

Tenax’s ability to provide products and services to its customers requires its partners to provide a variety of components and services. In addition, Tenax is required to procure certain components and services from U.S. government-approved sources. Heightened regulatory requirements that may apply to these sources can further limit the subcontractors and suppliers Tenax may use. Legislation, regulatory changes or other governmental actions, including product certification or stewardship requirements, sourcing restrictions, tariffs, export controls, embargoes, product authenticity, cybersecurity regulation and environmental standards may all affect Tenax’s subcontractors and suppliers.

From time to time, Tenax’s subcontractors and suppliers experience financial and operational difficulties outside of Tenax’s direct control, which may affect their ability to deliver the components and services Tenax needs.

Market values for Tenax’s aviation products fluctuate, and Tenax may be unable to recover costs incurred with respect to aircraft or aircraft equipment or parts.

Tenax makes a number of assumptions when determining the recoverability of aircraft, aircraft equipment, aircraft parts and other assets which it owns in support of its customers’ requirements. These assumptions include historical sales trends, current and expected usage trends, replacement values, current and expected lease rates, maintenance expenses, residual values, future demand and future cash flows. The value of any given aircraft model, or any equipment or parts applicable thereto, can vary significantly based on supply in the marketplace. In addition, reductions in demand for these assets or declining market values, as well as differences between actual results and the assumptions Tenax uses in determining the recoverability of its assets, could result in impairment charges in future periods, may adversely affect its business, financial condition, liquidity or results of operations.

28

Table of Contents

Tenax may not be able to recover aircraft or aircraft equipment or parts when a customer defaults on a contract, and even if Tenax is able to do so, it may have to expend significant resources in the recovery of such assets. Third-party liens on such assets could further impair Tenax’s ability to recover and sell or enter into a new contract with those assets.

When a customer defaults on its obligations under a contract and does not cure such default in a timely manner, Tenax typically seeks to terminate the applicable contract and recover the aircraft or aircraft equipment or parts. If a defaulting customer contests the termination and recovery or is under court protection, enforcement of Tenax’s rights under the contract may be difficult, expensive and time-consuming. In the event the aircraft or aircraft equipment or parts are located outside of the United States, Tenax may need to obtain governmental consents to export such aircraft or aircraft equipment or parts back to the United States. As a result, the relevant asset may not generate revenue for a prolonged period. In addition, Tenax will incur direct costs associated with recovering its aircraft or aircraft equipment or parts, which may include legal and similar costs, costs of transporting, storing and insuring the aircraft or aircraft equipment or parts and costs associated with necessary maintenance and recordkeeping to make the aircraft or aircraft equipment or parts available for a new contract or sale. During this time, Tenax will not realize revenue from the aircraft or aircraft equipment or parts being recovered and will continue to be obligated to pay any debt financing related to the aircraft or aircraft equipment or parts. In addition, when a customer has protection under the U.S. Bankruptcy Code, creditors (including Tenax) are automatically stayed from enforcing their rights.

The risks associated with customer defaults and asset recovery may be further compounded where third-party liens have attached to the relevant aircraft or aircraft equipment or parts. Liens in favor of third parties may be attached to aircraft or aircraft equipment or parts Tenax owns, and these liens may secure substantial sums that may in certain circumstances exceed the value of the particular aircraft or aircraft equipment or parts to which the liens have attached. In certain jurisdictions, a lien may give the lien holder the right to detain, in limited cases sell, or cause the forfeiture of the aircraft or aircraft equipment or parts subject to the lien. Liens held by third parties may have priority over Tenax’s and its creditors’ interest in the respective aircraft or aircraft equipment or parts because the third-party liens have priority under applicable law. These liens and lien holders could impair Tenax’s ability to recover and re-contract or sell its aircraft or aircraft equipment or parts. If Tenax’s customers do not discharge these liens, Tenax may find it necessary to pay the claims secured by such liens in order to recover the aircraft or aircraft equipment or parts subject to such third-party liens.

Tenax’s operations would be adversely affected by a shortage of skilled personnel or work stoppages.

Tenax depends on an educated and highly skilled workforce because of the complex nature of many of its products and services. Tenax’s ability to operate successfully and meet its customers’ demands could be jeopardized if Tenax is unable to attract and retain a sufficient number of qualified personnel, including qualified licensed mechanics, to conduct its business, or if Tenax experiences a significant or prolonged work stoppage. The increasing competition for highly skilled and talented personnel in the industries in which Tenax operates could result in higher compensation costs, difficulties in maintaining a capable workforce and leadership development and succession planning challenges. These and similar events may adversely affect its business, financial condition, liquidity or results of operations.

Tenax depends on continued availability of financing to manage its business and to execute its business strategy, and additional financing may not be available on terms acceptable to Tenax.

Tenax’s ability to manage its business and to execute its business strategy depends, in part, on the continued availability of debt and equity capital. Access to the debt and equity capital markets may be limited by various factors, including the condition of overall credit markets, general economic factors, interest rates, state of the aviation industry, financial performance and credit ratings. Debt and equity capital may not continue to be available to Tenax on favorable terms, or at all. Tenax’s inability to obtain financing on favorable terms may adversely affect its business, financial condition, liquidity or results of operations.

Tenax operates in highly competitive markets, and competitive pressures may adversely affect it.

Tenax’s business is highly competitive, and Tenax sometimes competes with larger companies that may have greater name recognition, greater financial resources and larger technical staff, as well as companies with a competitive advantage due to a small business designation. Within the aviation industry, companies have engaged

29

Table of Contents

in mergers and acquisitions to increase their competitive position. Tenax’s competitors may provide customers with different or greater capabilities or better contract terms than Tenax can provide, including past performance, geographic presence, price and the availability of qualified professional personnel. In addition, Tenax’s competitors may consolidate or establish teaming or other relationships among themselves or with third parties to increase their ability to address customers’ needs. If Tenax is unable to compete successfully against its current or future competitors, it may experience declines in revenue and market share, which may adversely affect its business, financial condition, liquidity or results of operations.

Tenax may need to make significant capital expenditures to keep pace with technological developments in the aviation industry.

The aviation industry, and in particular the specialized verticals in which Tenax operates, is constantly undergoing development and change, and new products, equipment and methods of repair and overhaul services are introduced on an ongoing basis. In order to keep pace with technological and other developments in its industry, Tenax sometimes needs to expend significant capital to develop information technology solutions, purchase new equipment, train its employees in the new methods of service or implement new processes to increase both efficiency and capacity. Not all projects may be implemented as anticipated as a result of various factors, including ability to meet customer specifications, delivery schedules and unique contractual requirements, supplier performance, subcontractor performance and Tenax’s ability to accurately estimate costs and timing associated with such projects. If projects do not achieve anticipated increases in efficiency or capacity, Tenax’s returns on these capital expenditures may be lower than expected. Failure to react quickly to industry trends and manage its offerings and innovation activities responsively could decrease the competitiveness of Tenax’s services, harm its reputation and negatively affect its ability to compete and attract top talent.

Tenax uses estimates in accounting for some of its contracts, and changes in its estimates could adversely affect its future financial results.

Contract accounting requires judgments relative to assessing risks, including risks associated with estimating contract transaction prices and costs, determination of certain contract prices, assumptions for schedule and technical issues, customer-directed delays and reductions in scheduled deliveries and unfavorable resolutions of claims and contractual matters. Due to the size and nature of certain of Tenax’s contracts, the estimation of total costs at completion is complicated and subject to certain variables. For example, Tenax must make assumptions regarding the length of time to complete certain contracts because costs include expected increases in wages and prices for materials, and Tenax must consider incentives or penalties related to performance on contracts and include them in the variable consideration to the extent that it is probable that a significant reversal in the amount of cumulative revenue recognized will not occur when the related uncertainty is resolved. Because of these judgments and estimation processes, it is possible that materially different amounts could be recorded if Tenax used different assumptions or if the underlying circumstances were to change. Changes in underlying assumptions, circumstances or estimates may adversely affect Tenax’s business, financial condition, liquidity or results of operations.

Tenax’s business could be negatively affected by cyber or other security threats or other disruptions.

Tenax’s business depends on information technology and computerized systems to communicate and operate effectively. Tenax stores sensitive data including proprietary business information, intellectual property and confidential employee or other personal data on its servers and databases. Tenax also relies on third parties to host certain enterprise systems that manage and host Tenax’s data and that of its customers. Tenax’s systems and technologies, or those of third parties on which Tenax relies, could fail or become unreliable due to equipment failures, software viruses, cyber threats or cyber incidents, ransomware attacks, employee error or malfeasance, terrorist acts, natural disasters, power or telecommunications failures, political or social unrest, pandemics or other public health issues or other causes. These threats arise in some cases as a result of Tenax’s role as a defense contractor. Tenax’s customers, including the U.S. government, are increasingly requiring cybersecurity protections and mandating cybersecurity standards in its products, and Tenax has incurred and expects to continue to incur additional cost to comply with such demands.

30

Table of Contents

If Tenax’s systems, data or any third-party service that Tenax uses are unavailable for any reason, Tenax’s customers may experience service interruptions, which could significantly affect Tenax’s operations, reputation, business and financial results. Lack of access to Tenax’s data and that of its clients, or failure of its systems or those of its third-party service providers, may result in interruptions in Tenax’s service, all of which may cause a loss in customers, refunds and/or material harm to Tenax’s reputation and operating results.

In addition, Tenax can make no assurances that it will be able to mitigate, detect, prevent, timely and adequately respond to or fully recover from the negative effects of cybersecurity incidents or other cybersecurity compromises, and such cybersecurity incidents, depending on their nature and scope, could potentially result in financial loss, reputational damage, damage to Tenax’s IT systems, data loss, litigation with third parties, theft of intellectual property, fines, customer attrition, diminution in the value of Tenax’s investment in research and development and increased cybersecurity protection and remediation costs due to the increasing sophistication and proliferation of threats, which in turn could adversely affect Tenax’s competitiveness and results of operations. Any imposition of liability may adversely affect Tenax’s business, financial condition, liquidity or results of operations.

Tenax’s operations depend on its aircraft and hangars, and damage to, or disruption affecting, those assets could materially adversely affect its business, financial condition or results of operations.

The operation of aircraft inherently involves a substantial degree of risk. Tenax’s aircraft and hangars are subject to hazards including mechanical failures, crashes, collisions, human error, fires and other operational incidents. These risks may result in damage to aircraft or other property and equipment, and, in certain circumstances, personal injury or loss of life, which could give rise to liability exposure, as well as suspension or reduction of operations, reduced flight hours, the grounding of affected aircraft or entire aircraft types or limitations in available ground facilities.

An accident or other incident involving Tenax’s aircraft could require the repair or replacement of the damaged asset and result in its temporary or permanent loss from service or use. Any such damage or loss of use could cause significant delays in provision of services and the loss of sales and customers, as well as result in potential liability exposure.

While Tenax maintains insurance coverage to cover certain risks of losses for damage to or destruction of aircraft and for interruption of its business, such insurance may not cover specific losses, and the amount of its insurance coverage may not be adequate to cover all of its losses.

Restrictive and financial covenants in the documents governing Tenax’s existing and any future indebtedness may limit its current and future operations, particularly Tenax’s ability to respond to changes in its business or to pursue its business strategies.

Certain current financing arrangements, including the Credit Agreement, dated as of January 7, 2026, among Tenax Holdco, LLC and the lenders party thereto (the “Tenax Credit Agreement”), and the Second Lien Credit Agreement, dated as of January 7, 2026, among Tenax Aerospace Holdings, LLC, certain other credit parties party thereto from time to time, and the lenders party thereto (the “Tenax Second Lien Credit Agreement”), require Tenax and its affiliates to comply with various restrictive covenants, and in certain cases contain financial covenants that require Tenax and its affiliates to comply with specified financial ratios and tests. Tenax’s or its affiliates’ failure to meet these covenants could result in default under these credit agreements and may result in a cross-default under other loan and debt agreements. In the event of a default and Tenax’s inability to obtain a waiver of the default, all amounts outstanding under such debt agreements could be declared immediately due and payable. Tenax’s or its affiliates’ failure to comply with these covenants may adversely affect its business, financial condition, liquidity or results of operations.

Restrictive covenants in the documents governing Tenax’s existing and any future indebtedness could adversely affect Tenax’s ability to finance its operations, make strategic acquisitions or investments, withstand a future downturn in its business or the economy in general, engage in business activities, including future opportunities, that may be in its interest, plan for or react to market conditions or otherwise execute its business strategies. In particular, the Tenax Credit Agreement and the Tenax Second Lien Credit Agreement contain change of control provisions that could delay or impair beneficial mergers and acquisitions involving Tenax.

Table of Contents

This proxy statement/prospectus is being furnished to you as an AIR stockholder as part of the solicitation of proxies by the AIR Board for use at the special meeting to consider and vote upon the stock issuance proposal, the authorized shares proposal and the written consent proposal.

PROPOSAL 1 — APPROVAL OF THE STOCK ISSUANCE PROPOSAL

(Item 1 on the AIR proxy card)

Subject to certain limited exceptions, Section 712 of the NYSE American Company Guide requires that our stockholders approve any issuance of shares of common stock where the issuance of common stock could result in an increase in outstanding common shares of 20% or more. In addition, Section 713(b) of the NYSE American Company Guide requires stockholder approval prior to the issuance of securities that will result in a change in control of the issuer.

As a result of the merger, AIR will issue to the Tenax Members as of immediately prior to the effective time a number of shares of AIR common stock which will result in an increase in outstanding common shares of more than 20%. In addition, completion of the merger will result in a change in control of AIR for purposes of Section 713(b) of the NYSE American Company Guide. Accordingly, the merger cannot be completed without the approval of the stock issuance proposal. Following the merger, approximately 96% of the outstanding shares of AIR common stock will be held by the Tenax Members. The merger agreement is attached as Annex A to this proxy statement/prospectus.

Pursuant to the merger agreement, approval of the stock issuance proposal is a condition to the consummation of the merger.

Approval of the stock issuance proposal requires, in accordance with Section 713(b) of the NYSE American Company Guide, that the votes cast “FOR” the stock issuance proposal exceed the votes cast “AGAINST” the stock issuance proposal. Abstentions and broker non-votes will have no effect on the outcome of this vote.

The AIR Board unanimously recommends that AIR stockholders vote “FOR” the stock issuance proposal.

PROPOSAL 2 — APPROVAL OF THE AUTHORIZED SHARES PROPOSAL

(Item 2 on the AIR proxy card)

The authorized shares proposal, if approved, will provide for an amendment to the articles of incorporation of AIR to increase the number of authorized shares of AIR common stock from 20 million to 200 million to permit issuance of a sufficient number of shares as merger consideration.

Pursuant to the merger agreement, approval of the authorized shares proposal is a condition to the consummation of the merger.

Approval of the authorized shares proposal requires, pursuant to Section 1.8.1 of our bylaws and NRS 78.390(1)(a)(1), that the votes cast “FOR” the authorized shares proposal exceed the votes cast “AGAINST” the authorized shares proposal. Under Section 1.8.1 of AIR’s bylaws, “votes cast” means all votes cast in favor of and against the proposal and does not include abstentions or broker non-votes. Abstentions and broker non-votes will have no effect on the outcome of this vote.

The AIR Board unanimously recommends that AIR stockholders vote “FOR” the authorized shares proposal.

PROPOSAL 3 — APPROVAL OF THE WRITTEN CONSENT PROPOSAL

(Item 3 on the AIR proxy card)

The written consent proposal, if approved, will provide for an amendment to the articles of incorporation of AIR to authorize stockholder action by written consent in lieu of a stockholder meeting at any time while NTC Group, Thomas Foley and Taran Bakker and their respective affiliates collectively beneficially own at least a majority of the voting power of the outstanding shares of AIR common stock.

Pursuant to the merger agreement, approval of the written consent proposal is a condition to the consummation of the merger.

35

Table of Contents

Approval of the written consent proposal requires, pursuant to NRS 78.390(1)(a)(2), the affirmative vote of the holders of shares representing at least a majority of the voting power of the outstanding shares of AIR common stock entitled to vote thereon as of the record date for the special meeting. A failure to vote, a broker non-vote or an abstention will each have the same effect as a vote “AGAINST” this proposal.

The AIR Board unanimously recommends that AIR stockholders vote “FOR” the written consent proposal.

PROPOSAL 4 — APPROVAL OF THE TRANSACTION COMPENSATION PROPOSAL

(Item 4 on the AIR proxy card)

Section 14A of the Exchange Act and Rule 14a-21(c) under the Exchange Act require that the Company seek a non-binding advisory vote from its stockholders to approve the compensation that may be paid or become payable to AIR’s Named Executive Officers in connection with the merger, as disclosed in this proxy statement/prospectus, including as described in the section entitled “The Merger — Potential Payments to AIR Named Executive Officers Upon Completion of the Merger” beginning on page 52 of this proxy statement/prospectus.

As an advisory vote, the transaction compensation proposal is not binding upon AIR, and approval of the transaction compensation proposal is not a condition to completion of the merger. Accordingly, to the extent that AIR is contractually obligated to pay the compensation, such compensation will be payable, subject only to the conditions applicable thereto, if the merger is consummated and regardless of the outcome of the advisory vote.

Approval of the transaction compensation proposal requires that the votes cast “FOR” the transaction compensation proposal exceed the votes cast “AGAINST” the transaction compensation proposal. Abstentions and broker non-votes will have no effect on the outcome of this vote. As noted above, this vote is advisory and non-binding and will not be determinative of whether such compensation is paid.

The AIR Board unanimously recommends that AIR stockholders vote “FOR” the transaction compensation proposal.

PROPOSAL 5 — APPROVAL OF THE ADJOURNMENT PROPOSAL

(Item 5 on the AIR proxy card)

We may propose to adjourn the special meeting for a period of not more than 30 days, if necessary or appropriate, including if we fail to receive a sufficient number of votes to approve the stock issuance proposal, the authorized shares proposal or the written consent proposal, for the purpose of soliciting additional proxies to approve the stock issuance proposal, the authorized shares proposal and/or the written consent proposal.

If the special meeting is so adjourned, stockholders who have already submitted their proxies will be able to revoke them at any time prior to their use. If you sign and return a proxy and do not indicate how you wish to vote on any proposal, or if you indicate that you wish to vote in favor of the stock issuance proposal, the authorized shares proposal or the written consent proposal but do not indicate a choice on the adjournment proposal, your shares of common stock will be voted in favor of the adjournment proposal. If you indicate, however, that you wish to vote against the stock issuance proposal, the authorized shares proposal or the written consent proposal, your shares of common stock will only be voted in favor of the adjournment proposal if you indicate that you wish to vote in favor of that proposal.

Approval of the adjournment proposal requires that the votes cast “FOR” the adjournment proposal exceed the votes cast “AGAINST” the adjournment proposal. Abstentions and broker non-votes will have no effect on the outcome of this vote.

The AIR Board unanimously recommends that AIR stockholders vote “FOR” the adjournment proposal.

The AIR Board has unanimously (i) determined that the merger agreement and the Transactions are fair to and in the best interests of AIR and its stockholders and (ii) adopted and approved the merger agreement and the Transactions, on the terms and subject to the conditions set forth in the merger agreement. Accordingly, the AIR Board unanimously recommends that AIR’s stockholders vote “FOR” the stock issuance proposal, the authorized shares proposal, the written consent proposal, the transaction compensation proposal and the adjournment proposal.

THE MERGER

This section describes the merger and the transactions contemplated thereby. The description in this section and elsewhere in this proxy statement/prospectus is qualified in its entirety by reference to the complete text of the merger agreement, a copy of which is attached as Annex A and is incorporated by reference into this proxy statement/prospectus. This summary does not purport to be complete and may not contain all of the information about the merger and the transactions contemplated thereby that is important to you. You are encouraged to read the merger agreement carefully and in its entirety. This section is not intended to provide you with any factual information about AIR or Tenax. Such information can be found elsewhere in this proxy statement/prospectus.

Merger

Pursuant to the merger agreement, at the effective time of the merger, Merger Sub will be merged with and into Tenax, with Tenax surviving the merger as a wholly owned subsidiary of AIR.

Merger Consideration; Adjustments to the Merger Consideration

At the effective time of the merger, Tenax units issued and outstanding immediately prior to the effective time will be converted into the right to receive the portion of the merger consideration allocated in respect thereof in Tenax’s capitalization schedule, which Tenax is required to deliver to AIR no less than two business days prior to the closing. Pursuant to the merger agreement, the merger consideration will consist of 126,900,000 shares (which number will be adjusted to 25,380,000 shares after giving effect to the proposed amendment to the articles of incorporation of AIR contemplated by the authorized shares proposal and the subsequent reverse stock split) of AIR common stock to be issued to the Tenax Members and, as applicable, reserved for issuance to the Tenax Warrantholders upon the exercise of their warrants.

A portion of the merger consideration is allocable to the Tenax Warrantholders. AIR will reserve for future issuance, upon exercise of the warrants, a number of shares of AIR common stock equal to the total merger consideration that would be payable to the Tenax Warrantholders if all Tenax Warrantholders exercised their warrants (if and to the extent they remain outstanding) immediately prior to the effective time.

Ownership of the Combined Company

As a result of the merger, the AIR stockholders as of immediately prior to the effective time will collectively own approximately 4% of the outstanding shares of AIR common stock, on a fully diluted basis, and the Tenax Members and Tenax Warrantholders will collectively own approximately 96% of the outstanding shares of AIR common stock, on a fully diluted basis. Accordingly, the merger will result in substantial dilution to existing AIR stockholders, and the Tenax Members will have a controlling interest in AIR following completion of the merger.

Redemption Rights Agreement

Prior to the closing, AIR will declare and issue, as a dividend to AIR stockholders as of the trading day immediately preceding the closing date, a right to cause AIR to redeem shares of AIR common stock that such AIR stockholders then own and continue to own on the first anniversary of the closing. The Redemption Rights will entitle the holders thereof to require AIR to purchase all or a portion of such AIR stockholder’s shares of AIR common stock for a redemption price, payable in cash, equal to 107.3% of the Debt Adjusted AIR Share Price, if the volume weighted average price of AIR common stock during the 20 trading days preceding the first anniversary of the closing is lower than 107.3% of the Debt Adjusted AIR Share Price. The Redemption Rights will not be transferable.

Financing of the Merger

The merger agreement requires that, at the closing of the merger, Tenax fund the repayment of AIR’s net senior and subordinated debt, amounting in the aggregate to approximately $26.233 million as of May 31, 2026.

Tenax relies on loans from a syndicate of banks to fund its operations. As of June 30, 2026, Tenax’s available borrowing capacity under its existing credit facility was $27 million. Tenax intends to seek, and believes it will be able to obtain, the necessary lender approvals to increase its borrowing capacity under its existing credit facility to refinance AIR’s net senior and subordinated debt or to otherwise obtain commitments from its lenders to satisfy its cash requirements at the closing of the merger.

38

Table of Contents

Factors that could affect Tenax’s ability to finance its obligations under the merger agreement include: (1) a downturn in the economy or markets that affects Tenax’s bank syndicate’s willingness to lend funds to Tenax; (2) the loss of one or more significant Tenax contracts without replacement business, which would reduce or limit Tenax’s borrowing capacity under its existing credit facility; and (3) one or more members of Tenax’s bank syndicate being forced to leave, or voluntarily leaving, the syndicate. Despite these risks, Tenax believes that, even if the bank syndicate were not willing to lend sufficient funds for Tenax to complete the merger, Tenax has access to other sources of debt and/or equity to refinance AIR’s net indebtedness. Those additional sources include other portfolio companies controlled by NTC Group principals, other past and present debt providers to Tenax and other portfolio companies controlled by NTC Group principals, and NTC Group principals. While Tenax believes it will have access to these and other potential financing sources by the closing of the merger, Tenax has not obtained, and is not currently seeking, binding committed financing for the transaction.

In addition, prior to closing, Tenax or one or more of its affiliates (which may include one or more Tenax Members) may, in their discretion, provide interim financial assistance to AIR to support its near-term liquidity needs, including in circumstances where AIR would otherwise require additional working capital or liquidity to continue operations during the period between signing and closing. Any such financial assistance would be for general corporate and working capital purposes and may take the form of one or more loan agreements, promissory notes, convertible promissory notes or other debt or equity instruments, with or without voting rights, with terms to be negotiated and which may include customary interest and repayment provisions. As of the date of this proxy statement/prospectus, no such arrangements have been entered into, no terms have been agreed to and there can be no assurance that any such financial assistance will be provided.

Reverse Stock Split

Under Section 341 of the NYSE American Company Guide, if a listed issuer engages in a reverse merger, it will be eligible for continued listing on the NYSE American only if the post-transaction entity meets the standards for initial listing. Companies listed on the NYSE American are subject to initial listing standards that require, among other things, a minimum share price of $4.00 per share under Section 101 of the NYSE American Company Guide. As of the date of this proxy statement/prospectus, the trading price of AIR’s common stock on the NYSE American is less than $4.00 per share, and there is no assurance it will not be below $4.00 per share at the effective time, meaning the combined company would fail to meet the standards for initial listing on the NYSE American. As a result, prior to the closing but, assuming the authorized shares proposal is approved at the special meeting, after the related amendment to the articles of incorporation of AIR to increase the number of authorized shares of AIR common stock from 20 million to 200 million becomes effective, AIR will file a certificate of change with the Nevada Secretary of State to effect, pursuant to NRS 78.207, a reverse stock split of the issued and outstanding shares of AIR common stock at a ratio of one (1) post-split share of AIR common stock for every five (5) pre-split shares of AIR common stock, while simultaneously reducing the number of then authorized shares of AIR common stock under the articles of incorporation of AIR by a corresponding factor, from 200 million to 40 million, with any fractional share of AIR common stock otherwise resulting from the split rounded up to the nearest whole share. Pursuant to NRS 78.207, the AIR Board has the authority to effect such a reverse stock split without stockholder approval. As a result of the reverse stock split, no fractional shares will be issued and any AIR stockholder otherwise entitled to a fractional share will be rounded up to the nearest whole share.

Background of the Merger

The AIR Board continuously evaluates AIR’s strategic direction with the objective of enhancing long-term stockholder value. As part of this ongoing process, the AIR Board regularly considers strategic alternatives, including organic growth opportunities and initiatives, capital allocation strategies, strategic partnerships and potential mergers or acquisitions.

In connection with these evaluations, in the first half of 2025, the AIR Board considered, among other things, (i) AIR’s ability to refinance its existing senior indebtedness with Webster Bank, National Association (“Webster Bank”) and its subordinated debt; (ii) the going concern opinion issued by AIR’s registered public accounting firm for the fiscal year ended December 31, 2024; (iii) the performance of AIR’s operations in the first half of 2025; (iv) management’s business plans and operating outlook; and (v) the potential to enhance stockholder value through one or more strategic transactions.

39

Table of Contents

After the AIR Board evaluated these considerations, on June 2, 2025, AIR engaged Kipps, an investment banking firm experienced in and highly regarded in the aerospace industry, to act as financial advisor on an exclusive basis in connection with a possible transaction involving AIR, including an acquisitive merger or sale of AIR or substantially all of its assets. Beginning in mid-June 2025 and continuing into August 2025, representatives of Kipps worked closely with AIR management to develop a strategy to pursue and effectuate a potential transaction and to prepare marketing materials describing AIR and its strategic attributes. AIR also engaged Baker Tilly US, LLP (“Baker Tilly”), an internationally recognized firm of independent accountants, to prepare a quality of earnings analysis to facilitate review of AIR’s historical financial statements by potential transaction counterparties.

In late June 2025, at the direction of the AIR Board, representatives of Kipps began contacting potential transaction counterparties. The AIR Board did not restrict the scope of such outreach, and representatives of Kipps contacted prospective financial and strategic counterparties, including competitors of AIR in the aerospace and defense industry. Over the course of June, July and August 2025, in consultation with the AIR Board, representatives of Kipps contacted 220 prospective counterparties (72 strategic counterparties, including private equity-backed portfolio companies, and 148 private equity groups). Of those contacted, 107 potential counterparties (29 strategic counterparties and 78 private equity groups) entered into confidentiality agreements with AIR and received a confidential information presentation describing the business and operational and financial attributes of AIR. These potential counterparties also received an instruction letter inviting them to submit a non-binding indication of interest (an “IOI”) to acquire all of the outstanding equity of AIR’s four subsidiaries or all or substantially all of the assets of AIR.

On August 8, 2025, Michael Recca, on behalf of AIR, met with Thomas C. Foley, Sr., founder and partner of NTC Group, a private investment firm that controls Tenax. Following the meeting, Mr. Foley submitted a non-binding IOI dated August 18, 2025, proposing that AIR and Tenax combine through a reverse merger transaction. In his letter, Mr. Foley proposed that AIR acquire Tenax for 90 million shares of AIR common stock, which would be issued to NEH and the other Tenax Members. This proposal was based on valuing (i) AIR at 7.5 times its estimated Run-Rate EBITDA for the second half of 2025 minus AIR’s net debt and (ii) Tenax at 9.0 times its estimated fourth quarter 2025 Run-Rate EBITDA minus net debt.1 In addition, for AIR stockholders who preferred to receive cash, Mr. Foley proposed that Tenax would offer to purchase shares of AIR common stock from such AIR stockholders at a price per share at a premium to the then market price of AIR’s common stock.

By the end of August 2025, eight potential counterparties (four strategic counterparties and four private equity groups), including Tenax, submitted written, preliminary, non-binding IOIs, which included indications of the value such potential counterparties attributed to AIR or its operating assets. Seven of these potential counterparties expressed interest in acquiring substantially all of the operating assets and assuming the liabilities of AIR, with enterprise valuations ranging from $28,000,000 to $55,000,000. Based on the content of the IOIs submitted by the potential counterparties and input obtained from preliminary discussions held by representatives of Kipps with such potential counterparties, AIR determined to invite seven potential counterparties (including Tenax) to continue participating in the sales process.

On September 24, 2025, the AIR Board established a special committee (the “Special Committee”), consisting of three independent directors — Messrs. Michael Porcelain, Michael Brand and David Buonanno — to facilitate the AIR Board’s evaluation of potential strategic transactions. The Special Committee was established to, among other things, review, evaluate and oversee discussions relating to potential strategic alternatives, including a possible merger or sale of AIR, and to provide advice and recommendations to the full AIR Board with respect to such matters.

In carrying out its responsibilities, the Special Committee was authorized to work with management and AIR’s financial and legal advisors, evaluate the strategic rationale and financial terms of any proposed transaction, consider potential conflicts of interest and assess whether any proposed transaction would be fair to, and in the best interests of, AIR and its stockholders. Upon its formation on September 24, 2025, the Special Committee requested that Mr. Michael Recca, AIR’s Director of Special Projects, assist the Special Committee in connection with its evaluation of potential strategic transactions. In this role, Mr. Recca provided information and support at the

direction of the Special Committee, including facilitating the preparation and review of financial and operational materials, coordinating the flow of information between management, the Special Committee, the AIR Board and AIR’s advisors and responding to requests for information from the Special Committee and its advisors. Mr. Recca did not participate in any deliberations or decision-making of the Special Committee.

The Special Committee met periodically from October 2025 to December 2025 to review developments relating to the sourcing and evaluation of strategic alternatives and reported its findings and recommendations to the full AIR Board for consideration.

Beginning in September 2025 and continuing through mid-October 2025, AIR conducted due diligence meetings, gave facility tours and had preliminary business discussions with the seven potential counterparties. After participating in management meetings in September 2025, two of the potential counterparties elected not to proceed further and five of the seven potential counterparties, which included Tenax, elected to continue in the process. In early October 2025, in coordination with representatives of Kipps, AIR established a virtual data room to facilitate due diligence investigations by the remaining five potential counterparties.

On September 24, 2025, AIR received a letter from Mr. Foley proposing that AIR acquire Tenax for 90 million shares of AIR common stock, which would be issued to NEH and the other Tenax Members. This proposal was based on valuing (i) AIR at 7.5 times its estimated Run-Rate EBITDA for the second half of 2025 minus net debt and (ii) Tenax at 9.0 times its estimated fourth quarter 2025 Run-Rate EBITDA minus AIR’s net debt.2 In addition, for AIR stockholders who preferred to receive cash, Mr. Foley proposed that Tenax would offer to purchase shares of AIR common stock from such AIR stockholders at a cash price of $3.50 per share.

On October 20, 2025, representatives of Kipps contacted Mr. Foley to provide an update on the AIR sales process and timeline and to confirm whether Tenax remained interested in continuing discussions with AIR. In this discussion, representatives of Kipps advised Mr. Foley that AIR had completed management meetings with all active bidders and that letters were sent seeking final proposals from the five remaining bidders no later than November 13, 2025. Mr. Foley indicated to the representatives of Kipps participating in the discussion that he was only interested in a “reverse merger” transaction structure, pursuant to which the Tenax Members would receive AIR common stock.

On November 13, 2025, a potential counterparty (“Counterparty A”) expressed a desire to continue to evaluate a transaction with AIR and submitted a proposal that did not provide a determinate valuation of AIR. Counterparty A also verbally advised representatives of Kipps that it was reviewing other strategic transactions, including a possible sale of its own stock or assets that would affect its ability to pursue and finance an acquisition of AIR, and asked for an extension of the period in which it could submit a bid.

On November 13, 2025, Tenax submitted a proposal for a combination of AIR and Tenax in which the Tenax Members would receive 98 million shares of AIR common stock. In addition, Tenax offered to purchase from AIR’s stockholders at the time of the closing of the transaction up to one million shares of AIR common stock for $4.00 per share and to grant all AIR stockholders immediately prior to the closing of the transaction a right to put their shares to the combined company approximately one year after the closing of the transaction at a price of $4.25 per share, if, during a 30-day measurement period prior, the average daily price of the shares were below $4.25 per share.

On November 14, 2025, another potential counterparty (“Counterparty B”), an independent wealth fund, submitted a proposal for the acquisition of substantially all of the assets and assumption of all of the liabilities of AIR for an enterprise valuation of $50,000,000, subject to further due diligence and a price adjustment based upon AIR’s net working capital as of closing.

On November 17, 2025, representatives of Kipps participated in a conference with the AIR Board in which it provided analyses of the bids submitted by Tenax and Counterparty B. The representatives of Kipps also described the proposal received from Counterparty A, noting for the AIR Board the lack of a clear valuation in Counterparty A’s proposal.

Table of Contents

Through the balance of November 2025, at the direction of the Special Committee, representatives of Kipps engaged in discussions with each of the three potential counterparties to clarify their respective proposals. During discussions with Counterparty A, Counterparty A did not provide clarity regarding its valuation of AIR, or whether it could consummate a transaction in light of the uncertainty of its own strategic plans, and repeatedly requested additional time to clarify its intentions.

Based on the uncertainty expressed by Counterparty A and its inability to move forward on a timely basis, and in light of the AIR Board’s belief that, due to a deterioration in AIR’s financial performance and concerns about AIR’s ability to refinance its debt obligations, AIR needed to consummate a transaction promptly, AIR determined not to pursue a transaction with Counterparty A, and representatives of Kipps informed Counterparty A of AIR’s decision during the week of November 24, 2025. Subsequently, Counterparty A did not seek to continue discussions regarding a transaction with AIR.

In mid-November 2025, the Special Committee directed AIR’s management to prepare updated financial forecasts for 2025 and 2026 (the “November 2025 Forecast”) to be provided by Kipps to Counterparty B and Tenax and to request best-and-final offers. The November 2025 Forecast was provided to Counterparty B and Tenax to enable them to make their best-and-final offers on the basis of the latest information available to the AIR Board. The November 2025 Forecast projected a deterioration in the performance of AIR and negative cash flows from operations through the first half of 2026, which was likely to result in a need on the part of AIR to increase its debt to maintain operations. During a conference on November 21, 2025, the Special Committee advised the rest of the AIR Board of the implications of the November 2025 Forecast, and the AIR Board discussed the various alternatives then available, including whether AIR could refinance all of its outstanding debt and, if so, whether the terms of any such refinancing would be acceptable.

During the week of November 24, 2025, subsequent to the receipt by Tenax of the November 2025 Forecast, Messrs. Porcelain and Recca met with Mr. Foley and other representatives of Tenax to discuss the November 2025 Forecast, prospects for a turn-around in AIR’s performance, the economics of the earlier Tenax proposals and the strategic benefits to Tenax of a transaction with AIR. Messrs. Porcelain and Recca advised Mr. Foley that, given there were other active bidders and the differences in the structures of the bids, as well as certain benefits to AIR from a sale of assets that would be unavailable if it consummated the reverse merger transaction proposed by Tenax, it was important for Tenax to consider meaningfully improving its proposal to ensure that it would be viewed as Tenax’s highest and best offer by the AIR Board. During the discussion, Messrs. Porcelain and Recca advised Mr. Foley that a transaction structure offering both (i) an optional upfront cash consideration to AIR’s stockholders and (ii) a full cash put right would be viewed favorably and would be likely to receive serious consideration by the AIR Board. This feedback was provided by Messrs. Porcelain and Recca to convey the types of transaction features that the AIR Board and the Special Committee believed could enhance certainty of value and address stockholder liquidity considerations.

On December 1, 2025, in response to the request for final bids, Counterparty B submitted a proposal for the acquisition of substantially all of the assets and assumption of all of the liabilities of AIR for an enterprise valuation of $55,000,000. Counterparty B’s proposal also included a net working capital adjustment that would have reduced net cash consideration to AIR’s stockholders by approximately $2,000,000 to $4,000,000.

On December 2, 2025, Mr. Foley sent a letter to AIR reiterating Tenax’s proposal for a transaction pursuant to which Tenax would combine with AIR, with AIR surviving as a public company and the Tenax Members receiving 94.4 million shares of AIR common stock in exchange for 100% of the membership interests in Tenax. To provide potential liquidity to those stockholders of AIR seeking cash, Tenax offered to purchase from AIR’s stockholders at the time of the closing of the transaction up to one million shares of AIR common stock for $4.10 per share and to grant all holders of shares of AIR common stock immediately prior to the closing of the proposed transaction a right to require the combined company to purchase their shares, exercisable on or about the first anniversary of the merger at a price of $4.40 per share, if, during a 30-day measurement period, the average daily price of the shares is below $4.40 per share. Tenax also proposed that all funded debt of AIR would be repaid in connection with the merger, unless the holders of such debt elected to remain lenders to the combined company. In making its offer, based upon information previously provided by AIR, Tenax assumed AIR would have EBITDA of $6 million for 2026. As an alternative, if the reverse merger proposal made by Tenax was not acceptable to AIR, Mr. Foley proposed that Tenax would combine with AIR, with the Tenax Members receiving 94.4 million shares of AIR following a sale of AIR’s operating assets. As part of this alternative transaction, for AIR stockholders who prefer to receive cash in the

transaction, the combined company following the merger would purchase up to one million shares of AIR common stock from such AIR stockholders for $4.10 per share plus the amount determined by subtracting $20.5 million from AIR’s net cash remaining at the time of the merger and dividing that result by 5,000,000. The combined company would also grant all holders of AIR shares immediately prior to the closing of the proposed transaction a right to require the combined company to purchase their shares, exercisable on or about the first anniversary of the merger at a price equal to 107.3% of the per share amount resulting from the above formula, if, during a 30-day measurement period, the average daily price of the shares were below such put price.

On December 3, 2025, after receiving the proposals from each of Counterparty B and Tenax, the Special Committee met to review and discuss various aspects of the proposals, which discussion included an evaluation of the potential benefits of a reverse merger transaction compared to a sale of AIR’s operating assets. The Special Committee considered the strategic, financial and execution risks associated with each alternative. Based on these discussions, the Special Committee advised the AIR Board that it believed a sale of only the operating assets would be difficult to achieve in a way that would enhance stockholder value and recommended that a full AIR Board meeting be convened to consider the two alternatives.

On December 5, 2025, the AIR Board met at AIR’s Bay Shore facility. All of the directors were present throughout the meeting. Representatives of Kipps joined the meeting via video conference. Representatives of Kipps distributed materials summarizing recent communications with the remaining bidders. In addition, representatives of Kipps provided preliminary and illustrative analyses of the bids submitted by Tenax and Counterparty B. Given the uncertainties of the discussions with Counterparty A, representatives of Kipps were not able to provide a meaningful financial analysis of any bid Counterparty A might make. Members of AIR management and AIR’s advisors discussed with the AIR Board various aspects related to the structural differences between the bids of Counterparty B and Tenax, one being a sale of assets and the other a merger, including possible tax implications of both transactions and certain uncertainties associated with a sale of assets, which could, in counsel’s opinion, result in AIR’s shares being delisted by NYSE American.

At its meeting on December 5, the AIR Board reviewed and compared the proposals received from the two remaining potential counterparties, Counterparty B, being an independent wealth fund, and Tenax, a successful participant in the aerospace and defense industry. The AIR Board noted that, based on its familiarity with the aerospace and defense industry and its financial resources, Tenax appeared better positioned to consummate a transaction on an accelerated timeline. In contrast, Counterparty B had indicated it would need to conduct extensive further due diligence, including an assessment of AIR’s working capital requirements prior to proceeding with a potential transaction. Counterparty B’s proposal included a potentially significant valuation deduction via a net working capital adjustment, which, combined with any reduction in price Counterparty B might seek as a result of its due diligence and the deterioration in AIR’s operating performance, caused the AIR Board to believe that ultimately the purchase price actually to be received from Counterparty B was likely to be significantly below its non-binding offer and that a favorable transaction was more likely to be consummated with Tenax as opposed to Counterparty B. In addition, given the successful track record of Tenax and its experience in the aerospace industry, the AIR Board believed that Tenax might succeed in increasing the value of the shares held by AIR’s stockholders and, in all events, was offering stockholders an opportunity to realize liquidity following a one-year holding period. Moreover, the AIR Board believed that the acquisition of AIR through a reverse merger was a central component of the plans of Tenax, as compared to the plans of Counterparty B, which was pursuing other unrelated acquisitions concurrently with the AIR transaction and which, at that time, had no other investments or experience in the aerospace industry. In addition, the AIR Board discussed that Tenax would be able to benefit from the expertise of AIR’s management and other personnel and any synergies between products and processes. On this basis, the AIR Board determined to move forward with Tenax to attempt to enter into a transaction.

On December 8, 2025, the AIR Board and representatives of Kipps met in Greenwich, Connecticut with Mr. Foley and members of the management of Tenax to further discuss Tenax’s business, financial performance and prospects. At the meeting, Mr. Foley gave a presentation regarding the current business of Tenax, its plans for expansion and Tenax’s financial wherewithal. Members of the AIR Board determined that Tenax had the financial capacity to complete the transaction envisioned and support AIR through an anticipated period of negative cash flow. In addition, at the meeting on December 8, 2025, the AIR Board concluded that Tenax and its team were dedicated to the aerospace industry and that AIR’s stockholders could benefit from Tenax’s expertise.

On December 9, 2025, upon being advised that AIR desired to move forward with a potential transaction with Tenax, Tenax advised that it required that AIR enter into an exclusivity agreement with Tenax before committing to expend the funds necessary to continue and potentially complete the process. On December 15, 2025, AIR and Tenax entered into an exclusivity agreement with respect to the proposed transaction. The exclusivity agreement provided for an exclusivity period through January 31, 2026, which would automatically extend through February 15, 2026 unless AIR delivered written notice of termination to Tenax on February 1, 2026. Pursuant to the exclusivity agreement, AIR was required to immediately cease all existing discussions and negotiations with any other party with respect to a potential acquisition of AIR and was prohibited from soliciting, encouraging or providing information to any other potential acquiror during the exclusivity period. Subsequent to the execution of the exclusivity agreement, the parties continued to conduct due diligence and financial reviews of their respective businesses.

On December 17, 2025, on behalf of AIR, Messrs. Porcelain, Scott Glassman and Recca and representatives of Kipps and Baker Tilly participated in a video conference with Mr. Foley and representatives of Forvis Mazars, LLP, on behalf of Tenax, to discuss various financial measurements of the operations of AIR and decisions made by AIR as to the allocation of certain expenses.

On December 18, 2025, Mr. Foley met with Messrs. Porcelain, Recca and Eric Lee of AIR at AIR’s facility in Barkhamsted, Connecticut to discuss operational issues at AIR’s facility in Barkhamsted.

On December 22, 2025, Cravath, Swaine & Moore LLP (“Cravath”), counsel to Tenax, delivered an initial draft of a term sheet setting forth the key provisions of the proposed transaction (the “December 22 Term Sheet”) to Ellenoff Grossman & Schole LLP (“EGS”), counsel to AIR. The December 22 Term Sheet provided that the transaction would be structured as a reverse triangular merger, pursuant to which a newly formed merger subsidiary of AIR would merge with and into Tenax, with Tenax surviving as a wholly owned subsidiary of AIR. The provisions of the December 22 Term Sheet generally were consistent with those contained in the Tenax letter of December 2, 2025, and provided a specific formula to determine the number of shares of AIR to be issued to the Tenax Members and the prices at which the combined company would (i) commence a tender offer for one million shares of AIR common stock upon consummation of the merger and (ii) redeem those shares put by holders of AIR’s common stock approximately one year after the merger. Specifically, the December 22 Term Sheet provided that AIR would issue 94.4 million shares of AIR common stock to the Tenax Members, subject to adjustment based upon (y) the number of shares of common stock and common stock equivalents AIR issued prior to consummation of the merger, other than an agreed upon pool to be awarded to AIR management, and (z) the excess of AIR’s outstanding indebtedness above $24.6 million at the time of completion of the merger. The December 22 Term Sheet contained other terms and provisions customary for a transaction such as the merger, including provisions with respect to the conduct of the business of AIR and Tenax pending the merger, a “no-shop” provision, the obligation of certain AIR stockholders and Tenax Members to support the proposed transaction, the right of the AIR Board to exercise its fiduciary rights and respond to a superior proposal, the conditions to each party’s obligation to consummate the merger, and the break-up fees and expense reimbursements to be paid to each party upon termination of the merger agreement.

On December 22, 2025, Messrs. Glassman, Porcelain and Recca and other representatives of AIR participated in a video conference with Kipps and representatives of Tenax during which the parties further discussed financial aspects of the operations of AIR and the potential impacts to the ongoing business of various fixed price contracts.

On December 28, 2025, EGS delivered a revised draft term sheet to Cravath that proposed revisions to certain of the economic and structural terms of the December 22 Term Sheet, including with respect to the mechanics for adjusting the merger consideration and the pricing of the tender offer and related stockholder liquidity rights, including AIR’s right to issue equity and equity derivatives during the period subsequent to execution of the merger agreement prior to closing.

On January 2, 2026, Cravath delivered a further revised draft term sheet to EGS (the “January 2 Term Sheet”), which reflected continued discussions between the parties and further refinement of the proposed transaction structure and economic terms, including the introduction of a debt-adjusted framework for determining merger consideration and stockholder liquidity pricing.

On January 5, 2026, the AIR Board and representatives of Kipps reviewed in detail the January 2 Term Sheet. During the week of January 5, 2026, Mr. Porcelain spoke with Mr. Foley regarding certain of the provisions of the January 2 Term Sheet. Shortly thereafter, AIR and Tenax determined that the parties had sufficiently clarified the key terms of the contemplated transaction, and the parties would begin to draft definitive documents in respect thereof.

On January 20, 2026, Mr. Foley and other representatives of Tenax met with members of AIR management to review the most recent financial forecasts that had been prepared by AIR and AIR’s plans for improving operations going forward.

Over the course of January and February 2026, the parties continued to review each other’s businesses and exchanged documents in connection with their respective due diligence efforts.

On January 23, 2026, the AIR Board met to review in detail the formula for adjusting the merger consideration contained in the January 2 Term Sheet. During the course of the meeting, it was noted that the adjustments would be based upon any issuances by AIR of equity and equity derivative securities prior to consummation of the merger and any increase in the amount of AIR’s debt above an agreed upon floor, consistent with the forecasts previously provided to Tenax. During the meeting, representatives of Kipps reviewed preliminary and illustrative scenarios illustrating the impact on the number of shares to be issued based on various assumed increases in AIR’s outstanding indebtedness. In addition, Messrs. Glassman and Recca discussed certain operational issues at AIR and the likely need to increase debt to maintain operations over the first half of 2026. Based upon the presentations, consistent with previous discussions among the directors and officers of AIR, the AIR Board determined that it was probable that the adjustments would result in the issuance of more shares to Tenax than the 94.4 million shares referenced in the January 2 Term Sheet. The AIR Board also determined that it was probable that the price to be received by AIR’s stockholders for shares they might tender in the tender offer to be conducted at the time of the merger or redeem one year after the merger would be less than the prices in the January 2 Term Sheet. At the meeting, each of the AIR Board members confirmed that he understood that AIR’s debt was likely to increase in the foreseeable future and the impact this would have on the adjustment formula that determined the number of shares to be issued to Tenax.

On January 30, 2026, Cravath delivered an initial draft of the original merger agreement (the “January 30 Merger Agreement”) to EGS.

On February 3, 2026, EGS and Cravath conferred regarding certain timing and procedural issues with respect to the January 30 Merger Agreement.

On February 5, 2026, after conferring with AIR management, EGS delivered a revised draft of the original merger agreement to Cravath (the “February 5 Merger Agreement”).

On February 6, 2026, the AIR Board held a meeting at which EGS reviewed the February 5 Merger Agreement for the directors and certain provisions were discussed in detail. It was noted that the ultimate tax structure of the proposed transaction had yet to be agreed upon, as Tenax was still examining the tax implications of different alternatives and that there would be no financial impact to AIR’s existing stockholders from either alternative structure. In addition, Messrs. Recca and Porcelain again reviewed how the number of shares to be issued to the Tenax Members and the price to be received for shares tendered or redeemed by existing AIR stockholders would be determined, focusing on the impact of increases in AIR’s debt. During the course of this discussion, the directors reviewed the status of AIR’s operations, current cash requirements and likely requirements over the next twelve months.

On February 7, 2026, a further revised draft of the original merger agreement responsive to certain concerns noted by EGS and AIR was received from Cravath.

On the morning of February 9, 2026, the parties and their respective counsel participated in a video conference, which focused on outstanding due diligence items, the anticipated delivery dates for such materials, drafting of forms of ancillary agreements to be prepared prior to execution of the original merger agreement and other actions that would need to be accomplished in order to execute the original merger agreement.

On February 11, 2026, Cravath delivered a further revised draft of the original merger agreement (the “February 11 Merger Agreement”) that included a more detailed schedule for the closing of the merger and exchange of the financial information necessary to compute the number of AIR shares to be issued to the Tenax Members, as well as the prices to be paid in the tender offer and upon exercise of the Redemption Rights.

On February 13, 2026, the AIR Board held a videoconference meeting at which senior AIR management and representatives of EGS and Kipps were present (the “February 13 Board Meeting”). Prior to the February 13 Board Meeting, the AIR Board had been provided with the February 11 Merger Agreement. A representative of EGS reviewed with the AIR Board the nature and scope of the AIR Board’s fiduciary duties in the context of evaluating the February 11 Merger Agreement.

At the February 13 Board Meeting, representatives of Kipps presented their financial analysis and rendered to the AIR Board Kipps’s oral opinion that as of that date and based upon and subject to the assumptions, limitations, qualifications and conditions described in Kipps’s written opinion (a draft of which had been provided before the AIR Board meeting), the unadjusted redemption price of $4.21 was fair, from a financial point of view, to the holders of AIR common stock (the “Kipps Oral Fairness Opinion”).

The AIR Board recognized that the actual redemption price would be determined pursuant to the original merger agreement and calculated based on a formula set forth in the original merger agreement prior to closing. AIR management instructed Kipps to assume that AIR’s net indebtedness at closing would equal $24,600,000, resulting in a calculated unadjusted redemption price of $4.21 per share, though the AIR Board determined that it would be likely that AIR’s net indebtedness at closing would exceed $24,600,000 and the amount of AIR’s net indebtedness as of December 31, 2025. The AIR Board permitted this assumption to enable Kipps to provide the analyses supporting its opinion, which the AIR Board could then use in considering the alternatives available to AIR in light of what the AIR Board believed AIR’s net indebtedness would be through the balance of 2026.

The AIR Board and representatives of EGS and Kipps discussed reasons for accepting the terms offered by Tenax rather than remaining independent or resuming negotiations with another party. As part of this discussion, members of the AIR Board and representatives of Kipps offered their perspectives on the terms of the February 11 Merger Agreement, including the potential liquidity through the tender offer and Redemption Rights, subject to the terms and conditions thereof. In particular, the grant of the Redemption Rights would allow current stockholders to retain their shares and potentially benefit from any increase in the price of the AIR common stock, while providing an opportunity to receive the agreed upon redemption price if the trading price of AIR common stock declined. The AIR Board also noted that the revenues of AIR remained depressed and that Webster Bank had recently announced its acquisition by Santander Bank and was exiting the asset based lending business, and accordingly was not inclined to extend AIR’s credit facility. On that basis, the AIR Board noted that, if AIR did not complete the merger, it likely would need to seek to raise additional capital to fund operations, whether through debt or equity financing. The AIR Board recognized that the terms of any debt would be less favorable to AIR than those of its current credit facility and, if AIR sought to offer equity, in light of its current performance, the price likely would be substantially below the then-current trading price of AIR’s common stock. The AIR Board also noted that Kipps, an internationally recognized investment banking firm in the aerospace and defense industries, had made a significant effort to market AIR, contacting 220 prospective counterparties, of which only 8 submitted non-binding indications of interest in moving forward with an acquisition of AIR. Following such discussion and deliberation, the AIR Board unanimously (i) determined that the February 11 Merger Agreement and the transactions contemplated thereby were fair to and in the best interests of AIR and its stockholders, (ii) adopted the February 11 Merger Agreement and approved the transaction documents thereunder and the transactions contemplated thereby and (iii) resolved to recommend that AIR’s stockholders vote in favor of the stock issuance proposal, the authorized shares proposal and the written consent proposal.

In making its determination, the AIR Board considered the limitations of the Kipps Oral Fairness Opinion, including that the opinion was based upon an assumed amount of AIR’s net indebtedness and AIR’s financial results as of December 31, 2025, and therefore did not reflect subsequent developments. In addition, the AIR Board had been advised by management that AIR’s business was expected to deteriorate further in 2026 and that as a result of anticipated increases in AIR’s indebtedness, the number of shares to be issued upon consummation of the merger agreement would likely exceed the number of shares that would be issued based upon AIR’s financial statements as of December 31, 2025. Management also advised the AIR Board of the significant risks and uncertainties regarding AIR’s ability to obtain the capital necessary to maintain its operations, including the timing and terms on which such capital might be available. In light of these considerations, the AIR Board recognized that the analyses underlying the Kipps Oral Fairness Opinion were based on assumptions that might not reflect AIR’s future financial condition and concluded that entering into the merger agreement, even if the eventual redemption price was materially lower than the value implied by such analysis, was in the best interests of AIR and its stockholders.

Following the conclusion of the February 13 meeting of the AIR Board, AIR received from Cravath a further revised draft of the original merger agreement (the “February 13 Merger Agreement”). The changes from the February 11 Merger Agreement were largely ministerial, and were intended to permit holders of certain warrants issued by Tenax to elect to delay exercising such warrants until after consummation of the merger without otherwise affecting the terms of the merger agreement. In addition, the February 13 Merger Agreement reflected an increase in the target amount of AIR common stock used in the formula for determining the Debt Adjusted AIR Share Price, which resulted in a lower implied Debt Adjusted AIR Share Price and, accordingly, a lower implied redemption price. EGS distributed the February 13 Merger Agreement, together with a summary to the members of the AIR Board. To ensure that each director understood the revisions and continued to support proceeding with the merger, an additional meeting of the AIR Board was held at 4:00 p.m. Eastern time on February 16, 2026, which was attended by all of the directors, senior management and representatives of EGS. EGS reviewed for the directors all of the revisions in the February 13 Merger Agreement. Following discussion of the revisions, the AIR Board concluded there were no substantive changes from the February 11 Merger Agreement that might affect the benefits of the merger to the AIR stockholders and resolved to approve the February 13 Merger Agreement, and confirmed that all actions taken by the AIR Board at its meeting on February 13 remained in the best interests of AIR and its stockholders.

Following this meeting, Messrs. Porcelain and Foley confirmed that both parties were prepared to move forward, and the original merger agreement was executed.

On February 17, 2026, before the opening of trading on the NYSE American, AIR and Tenax issued a joint press release announcing the execution of the original merger agreement.

On that same date, Kipps delivered a written opinion and updated presentation, each dated February 17, 2026, confirming that as of the date of such opinion, and based upon and subject to the assumptions, limitations, qualifications and conditions set forth therein, the unadjusted redemption price of $4.18 was fair, from a financial point of view, to the holders of AIR common stock (the “Kipps Written Fairness Opinion”). The Kipps Written Fairness Opinion reflected a decrease from the $4.21 unadjusted redemption price used by Kipps in rendering the Kipps Oral Fairness Opinion.

Over the course of February, March and April of 2026, AIR, Tenax and their respective legal counsel collaborated in drafting a preliminary proxy statement relating to the merger. On May 5, 2026, AIR filed a preliminary proxy statement with the SEC relating to the merger. On May 19, 2026, SEC staff informed AIR’s legal counsel that the SEC would not be commenting on the preliminary proxy statement.

Over the course of June 2026, AIR and Tenax discussed amending the original merger agreement to, among other things, replace the net indebtedness-based formula for determining the merger consideration with a fixed number of shares of AIR common stock, eliminate the previously contemplated tender offer, effect a reverse stock split of AIR common stock prior to the closing, and file a registration statement on Form S-4 with respect to the shares of AIR common stock to be issued to the Tenax Members as merger consideration. These revisions were intended to provide greater certainty as to the merger consideration and to facilitate the combined company’s satisfaction of the initial listing requirements of the NYSE American, including the requirement that shares of common stock have a minimum price of $4.00 per share and the requirement that the combined company have an aggregate market value of unrestricted publicly-held shares of at least $15 million. On June 25, 2026, the AIR Board met and approved the proposed revised commercial terms.

On June 29, 2026, Cravath delivered a draft of the merger agreement (the “June 29 Merger Agreement”) to EGS which, among other things, (i) set the merger consideration at 126,900,000 shares of AIR common stock (which number will be adjusted to 25,380,000 shares after giving effect to the proposed amendment to the articles of incorporation of AIR contemplated by the authorized shares proposal and the subsequent reverse stock split described in this proxy statement/prospectus); (ii) revised the definition of Debt Adjusted AIR Share Price to be fixed at $3.05 ($15.25 after giving effect to the reverse stock split), rather than calculated pursuant to a formula based on AIR net indebtedness; (iii) eliminated the tender offer that the parties previously contemplated AIR would commence following the closing; and (iv) included a requirement for AIR to file a registration statement on Form S-4 with respect to the shares of AIR common stock to be issued to the Tenax Members as merger consideration and added a condition to closing that such registration statement have become effective under

the Securities Act and not be subject to any stop order. The June 29 Merger Agreement further provided that, if AIR effected the reverse stock split or any other subdivision, stock dividend, split, combination, recapitalization, reclassification or similar change to its common stock on or after February 16, 2026 and prior to the closing, the merger consideration, the Debt Adjusted AIR Share Price and the other amounts payable under the merger agreement would be appropriately and equitably adjusted to preserve the same economic effect for the Tenax Members. Later that day EGS provided comments on the June 29 Merger Agreement. On June 30, 2026, Cravath delivered a revised draft of the amended and restated merger agreement to EGS (the “June 30 Merger Agreement”).

On July 2, 2026, the AIR Board held a meeting at which representatives of EGS reviewed the June 30 Merger Agreement and the revisions from the original merger agreement. During the course of the meeting the AIR Board, management and EGS discussed reasons for accepting the revised terms set forth in the merger agreement and other alternatives available to AIR. During the discussion, amongst other items, members of management noted the dilution to the current AIR stockholders that would occur as a result of the merger, the fact that the merger agreement required that AIR amend its articles of incorporation to permit stockholder action by written consent under conditions specified in the proposed resolution, that the current holders of AIR common stock would continue to be afforded the opportunity to cause the combined company to redeem their shares pursuant to the redemption rights agreement, subject to the terms and conditions thereof, and that the revised terms appeared to provide the most certain path to meeting the initial listing requirements of NYSE American as opposed to other possible actions. Following discussion, the AIR Board unanimously (i) determined that the June 30 Merger Agreement and the Transactions contemplated thereby were fair to and in the best interests of AIR and its stockholders, (ii) adopted the June 30 Merger Agreement and approved the transaction documents and the Transactions and (iii) resolved to recommend that AIR’s stockholders vote in favor of the stock issuance proposal, the authorized shares proposal and the written consent proposal.

Later on July 2, 2026, following the meeting of the AIR Board, AIR, Merger Sub and Tenax entered into the merger agreement which amended and restated the original merger agreement in its entirety.

Recommendation of the AIR Board; AIR’s Reasons for the Merger

At a meeting held on July 2, 2026, the AIR Board unanimously (i) determined that the merger agreement and the Transactions are fair to and in the best interests of AIR and its stockholders; (ii) adopted the merger agreement and approved the transaction documents and the Transactions; (iii) resolved to recommend that the stockholders of AIR vote in favor of the stock issuance proposal, the authorized shares proposal and the written consent proposal, in each case, on the terms and subject to the conditions set forth in the merger agreement; and (iv) directed that such matters be submitted to the stockholders of AIR for approval.

The AIR Board recommends that you vote “FOR” the stock issuance proposal; “FOR” the authorized shares proposal; “FOR” the written consent proposal; “FOR” the transaction compensation proposal and “FOR” the adjournment proposal.

In evaluating the Transactions, the AIR Board consulted with AIR’s management and legal and financial advisors to AIR and, in reaching its decision, the AIR Board considered a number of factors, both positive and negative, and potential benefits and risks involved with the merger agreement and the Transactions. Throughout 2025 and the first half of 2026, the AIR Board had considered AIR’s financial performance, AIR’s ability to service and refinance its existing indebtedness and, in light of these circumstances, the need to pursue a strategic transaction. In June 2025, the AIR Board initiated a process to pursue a transaction that would enhance value for AIR’s stockholders. The decision of the AIR Board to enter into the merger agreement was the result of careful consideration by the Board of numerous factors weighing positively in favor of the merger, including the following principal factors:

        AIR began the process of soliciting potential transaction counterparties in June 2025 and Kipps contacted 220 potential counterparties, and only eight potential counterparties submitted written preliminary proposals, confirming that the pool of potential counterparties was limited;

        of the potential counterparties that submitted proposals, only Tenax proposed a reverse merger that would enable AIR’s stockholders to realize a benefit from AIR’s status as a company listed on the NYSE American;

48

Table of Contents

        other transaction structures, such as an asset sale, may have subjected AIR to delisting from the NYSE American, thereby eliminating any perceived value attributable to its status as a listed company;

        the expectation that the combined company will have significantly higher revenues;

        the expectation that the combined company will have increased resources to invest in future acquisitions and other growth opportunities in comparison to AIR on a stand-alone basis;

        the expectation that the combined company will have the financial resources to enable it to access the credit markets at rates more favorable to AIR than those that are likely to be available to AIR on a stand-alone basis;

        the resulting equity stake in the combined company to be held by AIR’s stockholders upon completion of the merger and the ability of AIR’s stockholders to elect to require the combined company to redeem their shares, which are the result of arm’s-length negotiations;

        the AIR Board’s belief that the merger consideration and the structure of the transaction represent Tenax’s best and final offer;

        the expectation that the potential opportunities for the combined company to solicit and receive contract awards are greater than the opportunities currently available to AIR on a stand-alone basis;

        the terms of the Transactions provide AIR stockholders with a continuing equity stake in the combined company that provides AIR stockholders the opportunity to realize potential future share price growth and the potential for liquidity through Redemption Rights if they elect to cause the combined company to redeem their shares of AIR common stock;

        the AIR Board’s knowledge of AIR’s business, operations, financial condition, earnings and prospects and its knowledge of Tenax’s business, operations, financial condition, earnings and prospects, based on the results of AIR’s due diligence review of Tenax;

        the terms and conditions of the merger agreement, including the commitments by both AIR and Tenax to complete the Transactions and the likelihood of closing;

        the fact that the obligation of Tenax to consummate the closing under the merger agreement is not subject to a financing condition, and the AIR Board’s determination that Tenax has sufficient financial resources to cover (i) payment of AIR’s existing credit facilities and (ii) the fees and expenses reasonably expected to be incurred in connection with the merger;

        the limited number of approvals required from regulatory agencies and the likelihood that such approvals will be received without the imposition of terms and conditions that adversely affect the business and financial results of the combined company; and

        the fact that the merger agreement does not preclude a third party from making an unsolicited proposal for a competing transaction with AIR and that, under specified circumstances, AIR may furnish non-public information to and enter into discussions with such a third party regarding the competing transaction and the AIR Board may withdraw or modify its recommendations to our stockholders regarding the merger, including a recommendation to terminate the merger agreement in favor of entering into a competing transaction (subject to a termination fee).

The AIR Board also weighed the factors described above against a number of risks and other factors identified in its deliberations as weighing negatively against the merger, including:

        restrictions on the conduct of AIR’s business during the period between the execution of the merger agreement and the completion of the merger;

        the costs associated with the completion of the merger, including management’s time and energy and potential opportunity costs, and the risk of the failure to realize the benefits expected to be obtained in connection with the merger;

        the effect of any failure to complete the merger, including potential termination fees and stockholder and market reactions;

Table of Contents

        the challenges inherent in the combination of two businesses of the size and complexity of AIR and Tenax, including disruption to their respective businesses and commercial relationships, and the possible diversion of management attention for an extended period of time;

        the fact that, upon completion of the merger, the AIR Board will be composed of eight directors, with six of such directors identified by the Tenax Members and the balance subject to the approval of Tenax;

        the fact that, after the merger, holders of the common stock of AIR as of immediately prior to the effective time of the merger would collectively hold only approximately 4% of the common stock of the combined company on a fully diluted basis, and the combined company would effectively be controlled by a majority stockholder;

        the dilution of the overall interest of the public stockholders in the combined company following the merger and the resulting diminution in their aggregate interest in the future growth of the combined company;

        the risk that the lack of a public market for the membership interests of Tenax makes it difficult to evaluate the fairness of the merger and the Tenax Members may receive consideration in the merger that is more than the fair market value of their membership interests;

        uncertainties with respect to certain aspects of the business of Tenax and the AIR Board’s lack of deep experience with the business of Tenax;

        uncertainties with respect to certain aspects of the business of AIR and the lack of deep experience with the business of AIR on the part of the management of Tenax;

        the merger agreement precludes AIR from actively soliciting alternative proposals; and

        the termination fee and the obligation of AIR to reimburse Tenax for certain expenses may discourage third parties that might otherwise be interested in a business combination with, or acquisition of, AIR from making alternative proposals.

The AIR Board also considered the interests that the executive officers and directors of AIR have with respect to the merger in addition to their interests as stockholders of AIR generally (see the section entitled “— Interests of AIR’s Directors and Executive Officers in the Merger” beginning on page 50 of this proxy statement/prospectus).

Although the foregoing discussion sets forth the principal factors considered by the AIR Board in reaching its recommendation, it is not intended to be exhaustive and may not include all of the factors considered by the AIR Board, and each director may have considered different factors or given different weight to each factor. The above factors are not presented in any order of priority. In view of the variety of factors, the amount of information and the complexity of the matters considered, the AIR Board did not find it practicable to, and did not, make specific assessments of, or assign relative weights to, the specific factors considered in reaching its recommendation. The explanation of the reasoning of the AIR Board and certain information presented in this section are forward-looking in nature and should be read in light of the factors discussed in the section entitled “Cautionary Statement Regarding Forward-Looking Statements” beginning on page 32 of this proxy statement/prospectus.

After careful consideration, the AIR Board unanimously (i) determined that the merger agreement, the merger and the other Transactions are fair to and in the best interests of AIR and its stockholders and (ii) authorized, approved and declared advisable the merger agreement, the merger and the other Transactions, on the terms and subject to the conditions set forth in the merger agreement. Accordingly, the AIR Board unanimously recommends that AIR’s stockholders vote “FOR” the stock issuance proposal, the authorized shares proposal, the written consent proposal, the transaction compensation proposal and the adjournment proposal.

Interests of AIR’s Directors and Executive Officers in the Merger

In considering the recommendation of the AIR Board, AIR stockholders should be aware that AIR’s directors and executive officers have interests in the proposed merger that are different from, or in addition to, any interests they may have as stockholders. The AIR Board was aware of the different or additional interests set forth below (other than any interests that arose following AIR’s entry into the merger agreement) and considered such interests along with other matters in approving the merger agreement and the transactions contemplated by the merger agreement.

50

Table of Contents

AIR’s executive officers for the purpose of the discussion below are Scott Glassman (Acting Chief Executive Officer and President) and Brian Drisgula (Vice President of Finance). In accordance with SEC rules, this discussion also covers former directors and executive officers of AIR who served in such capacity at any time since January 1, 2025, which consists solely of Luciano Melluzzo (former President and Chief Executive Officer).

Subordinated Notes

Michael Taglich and Robert Taglich, directors of AIR, hold subordinated notes in the aggregate principal amount of $4,871,000 (the “Subordinated Notes”), of which $2,519,000 is convertible at the option of the holder into AIR common stock at $15.00 per share and $1,802,000 is convertible at the option of the holder into AIR common stock at $9.30 per share, and $550,000 is non-convertible. The Subordinated Notes mature October 1, 2026. Webster Bank, our principal lender, has required that payment of the amounts due pursuant to the Subordinated Notes be subordinated to payment of amounts owed under AIR’s credit facility. Tenax has agreed in the merger agreement that it or one of its affiliates will pay, or cause to be paid, our outstanding indebtedness, including the amount payable to Webster Bank and the Subordinated Notes in connection with the closing of the merger.

Treatment of AIR Equity Awards

Pursuant to the merger agreement, AIR Equity Awards, including those held by directors and executive officers, that are outstanding as of immediately prior to the effective time will continue on the same terms and conditions as were applicable to such AIR Equity Awards as of immediately prior to the effective time. These terms and conditions generally provide that if an award holder is terminated without “cause” within two years following the effective time, any unvested portion of his or her AIR Equity Awards will become fully vested. In addition, any vested options will generally remain exercisable until the earlier of the expiration date of the option and the date that is three months from such termination (or, in the case of termination due to death or permanent disability, a one- to three-year post-termination exercise period).

The table below sets forth, by type of AIR Equity Award, for each AIR director, an estimate of the aggregate value of such AIR Equity Awards granted that may be held by such individual at the effective time. The amounts set forth in the table below have been determined based on the number of AIR Equity Awards held by each individual as of July 10, 2026, the latest practicable date to determine such amounts before the filing of this proxy statement/prospectus, assuming that (i) the price per share of AIR common stock is $3.07, which represents the five-day average closing price following the announcement of the merger, (ii) the effective time occurs on September 1, 2026, which is the assumed closing date only for purposes of this compensation-related disclosure and (iii) the individuals included in the tables below do not receive any additional grants of AIR Equity Awards or forfeit any AIR Equity Awards prior to September 1, 2026; however, the values in the table below do reflect the expected vesting of AIR Equity Awards prior to such date.

Severance Benefits for Luciano Melluzzo

On March 11, 2026, Mr. Luciano Melluzzo resigned from his positions as President and Chief Executive Officer of AIR and from all other positions he held with AIR and its subsidiaries. In connection with his resignation, Mr. Melluzzo entered into a Separation and Release Agreement, dated March 13, 2026, which provides for (i) cash severance equal to two months’ base salary ($64,310.14) and (ii) the issuance of 12,159 shares of AIR common stock in respect of the accelerated settlement of vested AIR RSUs granted on February 12, 2026.

Arrangements with Tenax

As of the date of this proxy statement/prospectus, none of AIR’s directors or executive officers has entered into any agreement, arrangement or understanding with Tenax or any of its affiliates regarding employment, or providing for any compensation or benefits, following the effective time, and the merger is not conditioned upon any such agreement, arrangement or understanding being entered into.

Continuing Employee Benefits

The merger agreement provides for certain customary protections regarding the compensation and benefits of employees of AIR, including AIR’s executive officers, during their employment with AIR and its affiliates following the effective time for a period of up to one year. These provisions are described in more detail in the section entitled “The Merger Agreement — Employee Matters” beginning on page 77 of this proxy statement/prospectus.

Directors’ and Officers’ Indemnification

Pursuant to the terms of the merger agreement, directors and executive officers of AIR will be entitled to certain ongoing indemnification and coverage under directors’ and officers’ liability insurance policies following the merger. For a more detailed description of the provisions of the merger agreement relating to directors’ and officers’ indemnification, please see the section entitled “The Merger Agreement — Directors’ and Officers’ Indemnification and Insurance” beginning on page 77 of this proxy statement/prospectus.

Potential Payments to AIR’s Named Executive Officers Upon Completion of the Merger

This section sets forth the information required by Item 402(t) of SEC Regulation S-K regarding the compensation of each of AIR’s Named Executive Officers that is based on or otherwise relates to the merger and that will or may become payable to the Named Executive Officers at either the consummation of the merger or upon a qualifying termination of employment upon or following the consummation of the merger.

The table below sets forth, for the purposes of this merger-related compensation disclosure, the amount of payments and benefits that each Named Executive Officer would receive at the effective time based on the following assumptions:

        the effective time occurs on September 1, 2026, which is the assumed closing date only for purposes of this compensation-related disclosure;

        the number of unvested AIR Equity Awards held by each Named Executive Officer is determined as of July 10, 2026, the latest practicable date to determine such amounts before the filing of this proxy statement/prospectus, less any awards expected to vest in the ordinary course prior to September 1, 2026, and assuming no additional grants or forfeitures of AIR Equity Awards prior to September 1, 2026; and

        the price per share of AIR common stock is $3.07, which represents the five-day average closing price following the announcement of the merger.

The calculations in the table do not include amounts that AIR’s Named Executive Officers were already entitled to receive or were vested in as of the date of this proxy statement/prospectus. Moreover, as a result of the foregoing assumptions which may or may not actually occur or be accurate on the relevant date, the actual amounts, if any, to be received by a Named Executive Officer may materially differ from the amounts set forth below.

52

Table of Contents

For the purposes of this disclosure, “double-trigger” refers to payments that require two conditions, which are the consummation of the merger and a qualifying termination of employment, and “single-trigger” refers to payments or benefits that solely arise as a result of the consummation of the merger.

____________

(1)      For Mr. Glassman, the amounts set forth in the table reflect the aggregate dollar value of AIR common stock in respect of his unvested AIR Equity Awards, which will vest upon a termination without cause within two years following the effective time. These are therefore “double-trigger” payments. This amount excludes a grant of 12,159 vested RSUs to Mr. Glassman on February 12, 2026, which will be settled on February 12, 2027, because this grant was not made in connection with the merger.

(2)      Mr. Melluzzo resigned from his position as the President and Chief Executive Officer of the Company, effective March 11, 2026, and is no longer entitled to any payments or benefits in connection with the merger.

Interests of Certain Participants in the Solicitation

Our directors and executive officers may solicit proxies by telephone or otherwise in respect of the proposals to be considered at the special meeting and may be deemed to have been “participants” under the SEC rules in regard to such solicitation of AIR stockholders. AIR stockholders should be aware that all of the directors and Messrs. Glassman and Drisgula have interests in the merger that may be different from, or in addition to, those of AIR stockholders generally. All of our directors and Mr. Glassman will benefit from the treatment of outstanding AIR RSUs and AIR stock options and Michael Taglich and Robert Taglich will benefit from the payment of Subordinated Notes held by them as more fully described under “The Merger — Interests of AIR’s Directors and Executive Officers in the Merger — Subordinated Notes” beginning on page 51 of this proxy statement/prospectus. In addition, AIR’s directors and executive officers will benefit from the indemnification and insurance arrangements described under “The Merger Agreement — Directors’ and Officers’ Indemnification and Insurance” beginning on page 77 of this proxy statement/prospectus.

Opinion of AIR’s Financial Advisor

AIR retained Kipps to act as its financial advisor in connection with the Transactions. As part of this engagement, the AIR Board requested that Kipps evaluate the fairness to the holders of the AIR common stock, from a financial point of view, of the redemption price. At the meeting of the AIR Board on February 13, 2026, Kipps rendered its oral opinion to the AIR Board that as of the date of such opinion and based upon and subject to the assumptions, limitations, qualifications and conditions described in Kipps’s written opinion, an unadjusted redemption price of $4.21 was fair, from a financial point of view, to the holders of the AIR common stock. On February 17, 2026, Kipps delivered to the AIR Board a written opinion and an updated presentation, each dated February 17, 2026, confirming that, as of the date of such opinion and based upon and subject to the assumptions, limitations, qualifications and conditions described in such opinion, an unadjusted redemption price of $4.18 was fair, from a financial point of view, to the holders of the AIR common stock.

The full text of the written opinion of Kipps, dated February 17, 2026, which sets forth, among other things, the procedures followed, assumptions made, matters considered and qualifications and limitations on the scope of review undertaken in rendering its opinion, is attached as Annex B and is incorporated herein by reference into this proxy statement/prospectus in its entirety. The summary of the opinion of Kipps in this proxy statement/prospectus is qualified in its entirety by reference to the full text of the written opinion. You are urged to read Kipps’s opinion carefully and in its entirety. Kipps’s opinion was addressed to, and provided for the information and benefit of, the AIR Board (in its capacity as such) in connection with its evaluation of the Original Transactions. The opinion does not constitute a recommendation to the AIR Board or to any other persons in respect of the Original Transactions or the Transactions, including as to how any holder of shares of AIR common stock should vote or act in respect of the Original Transactions or the Transactions. Kipps’s opinion does not address the relative merits

53

Table of Contents

of the Original Transactions or the Transactions as compared to other business or financial strategies that might be available to AIR, nor does it address the underlying business decision of AIR to engage in the Original Transactions or the Transactions.

AIR stockholders should be aware that with the consent of the AIR Board, Kipps’s opinion was based on an assumed unadjusted redemption price of $4.18 per share, which was calculated based on a formula set forth in the original merger agreement prior to its amendment and restatement and assuming, at the direction of AIR’s management, that AIR’s net indebtedness at closing equals $24,600,000. The actual redemption price will be $3.27, which is materially lower than the $4.18 per share on which Kipps rendered its fairness opinion.

In connection with rendering its written opinion, Kipps, among other things:

        reviewed certain publicly available business and financial information relating to AIR that Kipps deemed to be relevant, including publicly available research analysts’ estimates;

        reviewed certain internal projected financial data relating to AIR prepared and furnished to Kipps by management of AIR, each as approved for Kipps’s use by AIR (the “Forecasts”);

        discussed with management of AIR their assessment of the past and current operations of AIR, the current financial condition and prospects of AIR, and the Forecasts;

        reviewed the reported prices and the historical trading activity of the AIR common stock;

        compared the financial performance of AIR and its stock market trading multiples with those of certain other publicly traded companies that Kipps deemed relevant;

        compared the financial performance of AIR and the valuation multiples relating to the unadjusted redemption price with the financial terms, to the extent publicly available, of certain other transactions that Kipps deemed relevant;

        reviewed the financial terms and conditions of a draft, dated as of February 16, 2026, of the original merger agreement, including Exhibit H thereto; and

        performed such other analyses and examinations and considered such other factors that Kipps deemed appropriate.

For purposes of Kipps’s analysis and opinion, Kipps assumed and relied upon the accuracy and completeness of the financial and other information publicly available, and all of the information supplied or otherwise made available to, discussed with or reviewed by Kipps, without any independent verification of such information (and Kipps did not assume responsibility or liability for any independent verification of such information), and further relied upon the assurances of the management of AIR that they were not aware of any facts or circumstances that would make such information inaccurate or misleading. With respect to the Forecasts, Kipps assumed with the consent of the AIR Board that the Forecasts were reasonably prepared on bases reflecting the best currently available estimates and good faith judgments of the management of AIR as to the future financial performance of AIR and the other matters covered thereby. Kipps expressed no view as to the Forecasts or the assumptions on which they were based.

For purposes of Kipps’s analysis and opinion, Kipps assumed, in all respects material to its analysis, that the final executed original merger agreement would not differ from the draft original merger agreement reviewed by Kipps, that the final executed redemption rights agreement would not differ from the draft terms and conditions set forth on Exhibit H of the original merger agreement reviewed by Kipps, that the representations and warranties of each party contained in the original merger agreement were true and correct, that each party would perform all of the covenants and agreements required to be performed by it under the original merger agreement and redemption rights agreement and that all conditions to the consummation of the Original Transactions, including the redemption, would be satisfied without waiver or modification thereof. Kipps further assumed, in all respects material to its analysis, that all governmental, regulatory or other consents, approvals or releases necessary for the consummation of the Original Transactions, including the redemption, would be obtained without any delay, limitation, restriction or condition that would have an adverse effect on AIR or the consummation of the Original Transactions, including the redemption, or reduce the contemplated benefits of the Original Transactions, including the Redemption Rights, to holders of AIR common stock.

54

Table of Contents

Kipps did not conduct a physical inspection of the properties or facilities of AIR and did not make or assume any responsibility for making any independent valuation or appraisal of the assets or liabilities (including any contingent, derivative or other off-balance sheet assets and liabilities) of AIR, nor was Kipps furnished with any such valuations or appraisals, nor did Kipps evaluate the solvency or fair value of AIR under any state or federal laws relating to bankruptcy, insolvency or similar matters. Kipps’s opinion was necessarily based upon information made available to Kipps as of the date of its opinion and financial, economic, market and other conditions as they existed and could be evaluated on the date of its opinion. Developments subsequent to Kipps’s opinion could affect its opinion and Kipps did not and does not have any obligation to update, revise or reaffirm its opinion.

Kipps was not asked to pass upon, and expressed no opinion with respect to, any matter other than the fairness to the holders of the AIR common stock, from a financial point of view, of the unadjusted redemption price. Kipps did not express any view on, and Kipps’s opinion does not address, the fairness of the proposed transaction to, or any consideration received in connection therewith by, the holders of any other class of securities, creditors or other constituencies of AIR, the fairness of the consideration to be paid or payable by AIR to the holders of membership units of Tenax or to be paid or payable by AIR in the tender offer contemplated in the original merger agreement, nor the fairness of the amount or nature of any compensation to be paid or payable to any of the officers, directors or employees of AIR, or any class of such persons, whether relative to the unadjusted redemption price or otherwise. Kipps was not asked to, nor did Kipps express any view on, and Kipps’s opinion does not address, any other term or aspect of the original merger agreement or the redemption rights agreement or the Original Transactions or the Transactions, including, without limitation, the structure or form of the Original Transactions or the Transactions, or any term or aspect of any other agreement or instrument contemplated by the original merger agreement or the redemption rights agreement or entered into or amended in connection with the original merger agreement or the redemption rights agreement. Kipps’s opinion does not address the relative merits of the Original Transactions or the Transactions, including the redemption, as compared to other business or financial strategies that might be available to AIR, nor does it address the underlying business decision of AIR to engage in the Original Transactions or the Transactions, including the redemption. Kipps’s opinion did not constitute a recommendation to the AIR Board or to any other persons in respect of the Original Transactions or the Transactions, including the redemption, including as to how any holder of shares of the AIR common stock should vote or act in respect of the Original Transactions or the Transactions, including the redemption. Kipps did not express any opinion as to the prices at which shares of AIR common stock will trade at any time, as to the potential effects of volatility in the credit, financial and stock markets on AIR or the Original Transactions or the Transactions, including the redemption, or as to the impact of the Original Transactions or the Transactions, including the redemption, on the solvency or viability of AIR or the ability of AIR to pay its obligations when they come due. Kipps is not a legal, regulatory, accounting or tax expert and assumed the accuracy and completeness of assessments by AIR and its advisors with respect to legal, regulatory, accounting and tax matters.

Set forth below is a summary of the material financial analyses reviewed by Kipps with the AIR Board on February 13, 2026, as updated by delivery of the updated presentation to the AIR Board on February 17, 2026. The presentation delivered to the AIR Board on February 13, 2026 in connection with rendering the oral opinion was identical to the February 17, 2026 presentation delivered to the Board on such date, other than the modified redemption price. The following summary, however, does not purport to be a complete description of the analyses performed by Kipps. The order of the analyses described and the results of these analyses do not represent relative importance or weight given to these analyses by Kipps. Except as otherwise noted, the following quantitative information, to the extent that it is based on market data, is based on market data that existed on or before February 12, 2026 (the last trading date prior to the rendering of Kipps’s oral opinion), and is not necessarily indicative of current market conditions.

For purposes of its analyses and reviews, Kipps considered general business, economic, market and financial conditions, industry sector performance and other matters, as they existed and could be evaluated as of the date of its opinion, many of which are beyond the control of AIR. The estimates contained in Kipps’s analyses and reviews, and the ranges of valuations resulting from any particular analysis or review, are not necessarily indicative of actual values or predictive of future results or values, which may be significantly more or less favorable than those suggested by Kipps’s analyses and reviews. In addition, analyses and reviews relating to the value of companies, businesses or securities do not purport to be appraisals or to reflect the prices at which companies, businesses or securities actually may be sold. Accordingly, the estimates used in, and the results derived from, Kipps’s analyses and reviews are inherently subject to substantial uncertainty.

55

Table of Contents

The following summary of Kipps’s financial analyses includes information presented in tabular format. In order to fully understand the analyses, the tables should be read together with the full text of each summary. The tables are not intended to stand alone and alone do not constitute a complete description of Kipps’s financial analyses. Considering the tables below without considering the full narrative description of Kipps’s financial analyses, including the methodologies and assumptions underlying such analyses, could create a misleading or incomplete view of such analyses.

For purposes of its opinion and the financial analyses described below, Kipps calculated the unadjusted redemption price pursuant to and in accordance with a formula set forth in the original merger agreement prior to its amendment and restatement, which defined the redemption price as 107.3% of the “Debt Adjusted AIR Share Price”, where for purposes of such formula:

        “Debt Adjusted AIR Share Price” meant the “Debt Adjusted AIR Equity Value” divided by the “AIR Share Target Amount”, subject to certain adjustments thereto;

        “Debt Adjusted AIR Equity Value” meant $20,500,000 minus the “AIR Excess Debt”;

        “AIR Excess Debt” meant the amount by which the “AIR Net Indebtedness” set forth in AIR’s closing capitalization schedule exceeded the “AIR Debt Target Amount”;

        “AIR Debt Target Amount” meant $24,600,000; and

        “AIR Share Target Amount” meant 5,256,325.

Applying the foregoing, the Debt Adjusted AIR Share Price was equal to the quotient of (A) an amount equal to (i) $20,500,000 minus (ii) the amount by which the AIR Net Indebtedness exceeded $24,600,000, divided by (B) 5,256,325.

For purposes of Kipps’s opinion and the financial analyses described below, AIR management instructed Kipps to assume that the AIR Net Indebtedness, as of December 31, 2025, was equal to the AIR Debt Target Amount of $24,600,000. Accordingly, Kipps calculated the unadjusted redemption price of $4.18 as 107.3% of the quotient of $20,500,000 divided by 5,256,325.

Summary of Kipps’s Financial Analyses

Selected Publicly Traded Companies Analysis

Kipps reviewed and compared certain financial information of AIR to corresponding financial multiples and ratios for the following selected publicly traded companies in the aerospace/defense industry (referred to in this section as the “selected companies”):

        Jabil Inc.

        Plexus Corp.

        Albany International Corp.

        Ducommun Incorporated

        Magellan Aerospace Corporation

For each of the selected companies, Kipps calculated enterprise value (defined as equity market capitalization plus total debt, plus preferred equity and minority interest, less cash and cash equivalents) as a multiple of (i) estimated 2026 EBITDA (such estimated 2026 earnings referred to as “2026E EBITDA” and such multiples referred to as “EV/2026E EBITDA”), and (ii) projected 2027 EBITDA (such estimated 2027 earnings referred to as “2027P EBITDA” and such multiples referred to as “EV/2027P EBITDA”), based on closing share prices as of February 6, 2026. Estimated and projected financial data of the selected companies were based on publicly available research analysts’ estimates obtained from Capital IQ, company filings and press releases as of February 6, 2026.

Based on the multiples it derived for the selected companies and based on its professional judgment and experience, Kipps applied a (i) EV/2026E EBITDA multiple reference range of 8.5x to 10.5x to AIR’s estimated EBITDA in calendar year 2026 as reflected in the Forecasts, and (ii) EV/2027P EBITDA multiple reference range of 7.5x to 9.5x to AIR’s projected EBITDA in calendar year 2027 as reflected in the Forecasts.

56

Table of Contents

Based on these ranges of implied total enterprise values, AIR’s estimated net debt as of December 31, 2025, and the number of fully diluted shares of AIR, each as provided by AIR’s management, this analysis indicated the following ranges of implied equity values per share of AIR common stock, each as compared to the unadjusted redemption price:

Benchmark

 

Implied Equity
Values
Per Share

EV/2026E EBITDA

 

$3.74 – $5.74

EV/2027P EBITDA

 

$2.67 – $4.70

Although none of the selected companies is directly comparable to AIR, Kipps selected these companies because they are publicly traded aerospace and defense firms, many of which possess specialized build-to-print/build-to-spec manufacturing expertise, that Kipps, in its professional judgment and experience, considered generally relevant to AIR for purposes of its financial analyses. In evaluating the selected companies, Kipps made judgments and assumptions with regard to general business, economic and market conditions affecting the selected companies and other matters, as well as differences in the selected companies’ financial, business and operating characteristics. Accordingly, an evaluation of the results of this analysis is not entirely mathematical. Rather, this analysis involves complex considerations and judgments regarding many factors that could affect the relative values of the selected companies and the multiples derived from the selected companies.

Selected Transactions Analysis

Kipps reviewed financial information related to the following selected transactions involving target companies in the aerospace/defense industry, specifically aerospace assembly and component manufacturing, announced between 2018 and 2025 (referred to in this section as the “selected transactions”).

For each selected transaction, Kipps calculated the implied enterprise value (defined as the target company’s implied equity value based on the consideration paid in the applicable transaction plus total debt plus debt-like liabilities plus minority interest less cash and cash equivalents) as a multiple of last twelve-month EBITDA for the target company at the time of the announcement of the applicable transaction (referred to in this section as “LTM EBITDA” and such multiple, “EV/LTM EBITDA”). Estimated financial data of the selected transactions were based on information dated as of the time of announcement of the relevant transaction.

Based on the multiples it derived from the selected transactions and based on its professional judgment and experience, Kipps selected a reference range of EV/LTM EBITDA multiples of 7.0x to 9.0x and applied this range of multiples to AIR’s estimated LTM EBITDA as of December 2025, based on publicly available business and financial information for AIR. Based on this range of implied total enterprise values, AIR’s estimated net debt and option exercise amount as of December 31, 2025 of $25.4 million and the number of fully diluted shares of AIR, each as provided by AIR’s management, this analysis indicated a range of implied equity values per share of AIR common stock of $0.82 to $2.54, as compared to the unadjusted redemption price.

Although none of the target companies or businesses reviewed in the selected transactions analysis is directly comparable to AIR and none of the selected transactions is directly comparable to the transaction, Kipps selected these transactions because they involve companies or businesses that Kipps, in its professional judgment and experience, considered generally relevant to AIR for purposes of its financial analyses. In evaluating the selected transactions, Kipps made judgments and assumptions with regard to general business, economic and market conditions and other factors existing at the time of the selected transactions, and other matters, as well as differences in financial, business and operating characteristics and other factors relevant to the target companies or businesses in the selected transactions. Accordingly, an evaluation of the results of this analysis is not entirely mathematical. Rather, this analysis involves complex considerations and judgments regarding many factors that could affect the relative values of the target companies or businesses in the selected transactions and the multiples derived from the selected transactions.

Discounted Cash Flow Analysis

Kipps performed a discounted cash flow analysis of AIR to calculate ranges of implied present values of the per share equity value of AIR utilizing estimates of the standalone unlevered, after-tax free cash flows that AIR was forecasted to generate over the period from January 1, 2026, through December 31, 2030, based on the Forecasts. Kipps calculated terminal values for AIR using two methods: (i) a perpetuity growth method — under which Kipps calculated terminal values for AIR by applying a range of perpetuity growth rates of 2.5% to 3.5%, which range was selected based on Kipps’s professional judgment and experience, to an estimate of the unlevered, after-tax free cash flows that AIR was forecasted to generate in the terminal year based on the Forecasts, and (ii) a terminal multiple method — under which Kipps calculated terminal values for AIR by applying a range of enterprise values to LTM EBITDA multiples of 7.0x to 9.0x, which range was selected based on Kipps’s professional judgment and experience, to an estimate of AIR’s terminal year EBITDA based on the Forecasts.

The cash flows and terminal values in each case were then discounted to present value as of December 31, 2025, using discount rates ranging from 13.0% to 15.0%, representing an estimate of AIR’s weighted average cost of capital, as estimated by Kipps based on its professional judgment and experience, to derive implied enterprise value reference ranges for AIR. Based on these ranges of implied enterprise values, AIR’s estimated net debt as of December 31, 2025, and the number of fully diluted shares of AIR, each as provided by AIR’s management, this analysis indicated ranges of implied equity values per share of AIR common stock as set forth in the table below, as compared to the unadjusted redemption price:

Premiums Paid Analysis

Using publicly available information, Kipps reviewed identified transactions involving acquisitions where a control premium was paid for a publicly traded target with a market capitalization less than or equal to $250 million between January 1, 2020 and December 31, 2025. Using publicly available information, Kipps calculated the premiums paid as the percentage by which the per share consideration paid or proposed to be paid in each such transaction exceeded the closing market price per the target companies one day, one week and one month prior to the announcement of each such transaction.

Based on the results of this analysis and its professional judgment and experience, Kipps applied a premium range of 14.5% to 71.4% to the closing price per share of AIR common stock of $3.30 on January 16, 2026. This analysis indicated a range of implied equity values per share of AIR common stock of $3.78 to $5.66, as compared to the unadjusted redemption price.

Miscellaneous

The foregoing summary of Kipps’s financial analyses does not purport to be a complete description of the analyses or data presented by Kipps to the AIR Board. In connection with the review of the Original Transactions by the AIR Board, Kipps performed a variety of financial and comparative analyses for purposes of rendering its opinion. The preparation of a fairness opinion is a complex process and is not necessarily susceptible to partial analysis or summary description. Selecting portions of the analyses or of the summary described above, without considering the analyses as a whole, could create an incomplete view of the processes underlying Kipps’s opinion. In arriving at its fairness determination, Kipps considered the results of all the analyses and did not draw, in isolation, conclusions from or with regard to any one analysis or factor considered by it for purposes of its opinion. Rather, Kipps made its determination as to fairness on the basis of its professional judgment and experience after considering the results of all the analyses. In addition, Kipps may have given various analyses and factors more or less weight than other analyses and factors, and may have deemed various assumptions more or less probable than other assumptions. As a result, the ranges of valuations resulting from any particular analysis or combination of analyses described above should not be taken to be the view of Kipps with respect to the actual value of the shares of AIR common stock. Further, Kipps’s analyses involve complex considerations and judgments concerning financial and operating characteristics and other factors that could affect the acquisition, public trading or other values of the companies used, including judgments and assumptions with regard to industry performance, general business, economic, market and financial conditions and other matters, many of which are beyond the control of AIR or its advisors. Rounding may result in total sums set forth in this section not equaling the total of the figures shown.

Kipps prepared these analyses for the purpose of providing an opinion to the AIR Board as to the fairness to the holders of the AIR common stock, from a financial point of view, of the unadjusted redemption price. These analyses do not purport to be appraisals or to necessarily reflect the prices at which the business or securities actually may be sold. Any estimates contained in these analyses are not necessarily indicative of actual future results, which may be significantly more or less favorable than those suggested by such estimates. Accordingly, estimates used in, and the results derived from, Kipps’s analyses are inherently subject to substantial uncertainty, and Kipps assumes no responsibility if future results are materially different from those forecasted in such estimates.

Kipps’s financial advisory services and its opinion were provided for the information and benefit of the AIR Board (in its capacity as such) in connection with its evaluation of the proposed Original Transactions. The issuance of Kipps’s opinion was approved by an Opinion Committee of Kipps.

Kipps did not recommend any specific amount of consideration to the AIR Board or AIR management or that any specific amount of consideration constituted the only appropriate consideration in the transactions for the holders of the AIR common stock.

Pursuant to the terms of Kipps’s engagement letter with AIR, AIR has agreed to pay Kipps a fee for its services in the aggregate amount of approximately $1.7 million, of which (i) $100,000 was payable upon execution of the engagement letter and is fully creditable against any fee payable upon the consummation of the merger, (ii) $350,000 was payable upon delivery of Kipps’s opinion in connection with the original merger agreement and is fully creditable against any fee payable upon the consummation of the merger and (iii) the remainder will be payable contingent upon the consummation of the merger. AIR has also agreed to reimburse Kipps for certain of its expenses and to indemnify Kipps against certain liabilities arising out of its engagement.

During the two-year period prior to the date of its opinion, Kipps and its affiliates have not been engaged to provide financial advisory or other services to AIR and it has not received any compensation from AIR during such period. In addition, during the two-year period prior to the date of its opinion, Kipps and its affiliates have not been engaged to provide financial advisory or other services to Tenax and it has not received any compensation from Tenax during such period. Kipps may provide financial advisory or other services to AIR and Tenax in the future, and in connection with any such services Kipps may receive compensation.

Certain Unaudited Prospective Financial Information Used by Our Board of Directors and Financial Advisor

AIR does not, as a matter of course, publicly disclose detailed long-term financial forecasts or internal projections as to future performance, earnings or other results given, among other reasons, the uncertainty of the underlying assumptions and estimates. However, in connection with the effort to solicit counterparties and provide them with current financial information, AIR management prepared the Forecasts, which were provided to certain counterparties, the AIR Board and Kipps for its use and reliance in connection with its financial analyses and opinion. The Forecasts speak only as of the time they were prepared and provided to the AIR Board.

The Forecasts were not prepared for the purpose of public disclosure, and were not prepared in compliance with published guidelines of the SEC or the guidelines established by the American Institute of Certified Public Accountants for preparation and presentation of financial forecasts or projections. The Forecasts were based on numerous variables and assumptions that are inherently uncertain and may be beyond AIR’s control. Accordingly, the Forecasts may not be realized and actual results may differ materially from those reflected in the Forecasts. The summary of the Forecasts included in this proxy statement/prospectus is not intended to influence your decision whether to vote in favor of any of the proposals at the special meeting. The inclusion of this information in this proxy statement/prospectus should not be regarded as an indication that AIR or any of its affiliates, officers, directors, employees, advisors or other representatives considered, or now considers, the Forecasts to be material or necessarily predictive of actual future results or events, and the Forecasts should not be relied upon as such.

Neither AIR’s independent auditors nor any other independent accountants have compiled, examined or performed any procedures with respect to the Forecasts, nor have they expressed any opinion or any other form of assurance on such information or its achievability, and they assume no responsibility for, and disclaim any association with, the Forecasts.

Tenax’s Reasons for the Merger

In evaluating the merger and the other Transactions, the Tenax Board, with the assistance of Tenax’s management and advisors, weighed a number of factors, both favorable and unfavorable. The factors weighing in favor of the merger included:

        the opportunity to combine Tenax with an established publicly traded aerospace and defense company, creating a platform with broader capabilities, customer relationships and growth prospects than Tenax has on a stand-alone basis;

        the complementary nature of the two businesses, AIR’s manufacturing of precision components and assemblies for aerospace and defense contractors, and Tenax’s special mission aircraft and related aviation equipment and services for the governments and other customers, positioning the combined company to participate across a broader portion of the aerospace and defense value chain;

        the Tenax Board’s expectation of continued growth in demand for special mission aviation supporting national security and public safety missions, which the combined company is better positioned to pursue than Tenax alone;

        the access to the public capital markets without the time, cost and execution risk associated with a traditional initial public offering, providing the combined company with a publicly traded currency that can be used to support future acquisitions and other growth opportunities;

        AIR’s long operating history and reputation in the aerospace and defense industry, its established relationships with leading aerospace and defense prime contractors, its funded backlog and unfilled contract value, its skilled workforce and its manufacturing facilities;

        the fact that the Tenax Members will retain a substantial majority of the economic interest in, and voting power of, the combined company and will continue to participate in any future growth and appreciation in the value of the combined company;

        the opportunity for the Tenax Members to hold publicly traded securities that may provide greater liquidity over time than their existing interests in a privately held company, subject to applicable securities laws and contractual restrictions; and

        the anticipated governance structure of the combined company, including the right of the Tenax Members to designate a majority of the members of the board of directors of the combined company at the closing.

The Tenax Board also considered a number of potentially negative factors including:

        the risks and costs associated with operating as a public company, including increased legal, accounting, compliance, reporting and governance obligations;

        AIR’s financial condition, the impending expiration and non-renewal of AIR’s senior credit facility, its negative projected cash flows, need for additional capital and the risk of further deterioration;

        the cash Tenax or the combined company must fund for the Transactions, including to repay AIR’s indebtedness and on any exercise of the Redemption Rights;

        the risks of combining two different operating models and the possibility that the anticipated benefits may not be realized;

        the risk that the merger is not completed, including the resulting harm to Tenax’s business and relationships, the termination fee and expense reimbursement payable in certain circumstances;

        the risk that the market price of AIR common stock following the merger may not reflect the intrinsic value of the combined company and may be subject to significant volatility due to factors affecting the combined company, the aerospace and defense industry or the broader equity markets; and

        the other risks described in the section entitled “Risk Factors” beginning on page 16 of this proxy statement/prospectus.

Table of Contents

Although the foregoing discussion sets forth the principal factors considered by the Tenax Board, it is not intended to be exhaustive and may not include all of the factors considered by the Tenax Board, and each member of the Tenax Board may have considered different factors or given different weight to each factor. The above factors are not presented in any order of priority. In view of the variety of factors, the amount of information and the complexity of the matters considered, the Tenax Board did not find it practicable to, and did not, make specific assessments of, or assign relative weights to, the specific factors considered. The explanation of the reasoning of the Tenax Board and certain information presented in this section are forward-looking in nature and should be read in light of the factors discussed in the section entitled “Cautionary Statement Regarding Forward-Looking Statements” beginning on page 32 of this proxy statement/prospectus.

Interests of Tenax’s Managers and Executive Officers in the Merger

Certain members of the Tenax Board and certain of Tenax’s executive officers have interests in the merger that are different from, or in addition to, the interests of Tenax Members generally. These interests may present them with actual or potential conflicts of interest, and these interests, to the extent material, are described below.

Ownership Interests

As of June 30, 2026, Tenax’s then-current non-employee managers and executive officers beneficially owned (indirectly through membership interests in NEH and Managers Equity, LLC), in the aggregate, approximately 78% of the Tenax units. Such Tenax units will be converted into shares of AIR common stock at the effective time.

Management Following the Merger

Two members of the Tenax Board and three of Tenax’s executive officers are expected to become directors and executive officers, respectively, of the combined company upon the closing of the merger, in connection with which they may enter into new employment agreements to reflect their status as executive officers of a publicly-traded company. For more information, see the sections entitled “Management and Directors of the Combined Company” beginning on page 146 of this proxy statement/prospectus and “Executive Officer and Director Compensation of the Combined Company” beginning on page 151 of this proxy statement/prospectus.

Certain Relationships and Related Party Transactions

Thomas Foley, Chairman of Tenax, and Taran Bakker, a member of the Tenax Board, are parties to certain agreements with Tenax and will be parties to certain agreements with the combined company following the merger. For more information, see the section entitled “Certain Relationships and Related Party Transactions of the Combined Company” beginning on page 153 of this proxy statement/prospectus.

Governance of AIR Following the Merger

Board of Directors

Following the consummation of the merger, the AIR Board will be composed of no fewer than eight directors, which shall consist only of (a) no fewer than six individuals designated by Tenax, namely Thomas Foley, Taran Bakker, Michael Ewald, Donald Fawcett, Bryan Fenton, DeWolfe Miller and John Young, and (b) two individuals to be mutually agreed upon by Tenax and AIR, namely [•] and [•], to hold office in accordance with the articles of incorporation and bylaws of AIR.

Michael Ewald, Donald Fawcett, Bryan Fenton, DeWolfe Miller, John Young, [•] and [•] are expected to be “independent directors” within the meaning of Item 407(a)(1) and NYSE American Rule 803A(2).

Following the consummation of the merger, the Audit Committee will be composed of members who meet the independence requirements set forth by the SEC, in the NYSE American listing requirements and the Audit Committee charter. Each member of the Audit Committee will be financially literate in accordance with the NYSE American listing requirements.

For more information, see the section entitled “Management and Directors of the Combined Company” beginning on page 146 of this proxy statement/prospectus.

Table of Contents

Management

AIR’s executive team following the merger will draw on the leadership teams of AIR and Tenax. In particular, Jim Linder, Ignacio Ladegui and Alan Oswalt, current executive officers of Tenax, will become Chief Executive Officer, Chief Financial Officer and EVP of Operations, respectively, of the combined company.

Tenax and its members, through the date on which the merger agreement was signed by all parties, made no arrangements with, and made no offers to, any members of AIR’s management team regarding continued employment with AIR.

For more information, see the section entitled “Management and Directors of the Combined Company” beginning on page 146 of this proxy statement/prospectus.

Controlled Company

Following the consummation of the merger, AIR will be a “controlled company” for purposes of Section 801(a) of the NYSE American Company Guide and, if and for so long as it so qualifies, intends to rely on exemptions from certain governance standards.

Under Section 801(a), a company in which over 50% of the voting power is held by an individual, a group or another company is a “controlled company” and is exempt from certain corporate governance requirements, including requirements that (1) a majority of AIR’s board of directors consist of independent directors, (2) director nominees be selected or recommended for selection by a majority of the independent directors or by a nominating committee composed solely of independent directors and (3) compensation of the chief executive officer be determined or recommended to the board of directors by a majority of its independent directors or by a compensation committee composed of independent directors. The controlled company exemption does not modify the independence requirements for the Audit Committee, and AIR intends to continue to comply with the requirements of the NYSE American rules with respect thereto.

Smaller Reporting Company

Following the consummation of the merger, AIR is expected to qualify as a “Smaller Reporting Company” for purposes of Section 801(h) of the NYSE American Company Guide and, if and for so long as it so qualifies, intends to rely on exemptions from certain governance standards.

Under Section 801(h), a company that satisfies the definition of smaller reporting company in Rule 12b-2 of the Exchange Act, meaning it is an issuer that is not an investment company, an asset-backed issuer or a majority-owned subsidiary of a parent that is not a smaller reporting company and that (1) has a public float of less than $250 million or (2) has annual revenues of less than $100 million and either (i) no public float or (ii) a public float of less than $700 million, is a “Smaller Reporting Company”. Smaller Reporting Companies are only required to maintain a board of directors composed of at least 50% independent directors (rather than a majority of independent directors) and an audit committee of at least two independent members (rather than three independent members). In addition, Smaller Reporting Companies are not subject to the same independence requirements for the compensation committee and compensation consultants.

Closing and Effective Time of the Merger

The closing of the merger will take place on the third business day following the satisfaction or written waiver, where permissible, of the conditions to the closing of the merger (other than those conditions that by their nature are to be satisfied at the closing, but subject to the satisfaction or written waiver, where permissible, of such conditions), or at such other time and date as shall be agreed in writing between AIR and Tenax. Subject to the satisfaction or waiver of the conditions to the closing described in the section entitled “The Merger Agreement — Conditions to Completion of the Merger” beginning on page 80 of this proxy statement/prospectus, it is currently anticipated that the merger will close in September 2026. It is possible that factors outside the control of both parties could result in the merger being completed at a different time, or not at all.

As soon as practicable on the closing date, Tenax will cause the certificate of merger to be filed with the Secretary of State of the State of Delaware in such form as is required by, and executed in accordance with, the relevant provisions of the DLLCA. The merger will become effective upon the filing of the certificate of merger with the Secretary of State of the State of Delaware, or such later date and time as is specified in the certificate of merger and agreed to by AIR and Tenax in writing.

Table of Contents

Regulatory Approvals

Completion of the merger is conditioned on, among other things, the expiration or termination of the applicable waiting periods under the HSR Act, the receipt of any required approvals or the expiration or termination of any applicable waiting periods under Antitrust Laws of certain other specified jurisdictions, if applicable, and the absence of any law or order enacted, issued, promulgated, enforced or entered, whether temporary, preliminary or permanent, which is then in effect and has the effect of enjoining, restraining, prohibiting or otherwise preventing consummation of the Transactions.

Under the HSR Act and the rules promulgated thereunder, the merger may not be completed until notification and report forms have been filed with the FTC and the DOJ and the applicable waiting period, or any extensions thereof, has expired or been terminated. The initial HSR Act waiting period is up to 30 days following the filing of the notification and report forms, unless earlier terminated by the FTC and the DOJ.

Pursuant to the merger agreement, each party has agreed to use its reasonable best efforts to obtain all necessary actions or nonactions, consents, approvals and waivers from, and to give any necessary notices to, governmental authorities and to make all necessary registrations, declarations and filings (including filings that are required or advisable under the HSR Act and other registrations, declarations and filings with, or notices to, governmental authorities, that may be required or advisable under other applicable antitrust, competition or pre-merger notification laws of any jurisdiction), if any. Pursuant to the merger agreement, Tenax and its affiliates are not required to agree to any prohibition or limitation on their ownership or operation of their businesses, any divestiture, hold-separate arrangement or any other restriction on their ability to operate their businesses, nor are they obligated to litigate before the FTC or DOJ, in order to obtain regulatory clearance.

On May 15, 2026, Thomas Foley filed a notification and report form pursuant to the HSR Act with the FTC and the DOJ with respect to his proposed acquisition of AIR common stock in connection with the merger. The applicable waiting period expired on June 15, 2026.

At any time before or after consummation of the merger, notwithstanding the expiration or termination of the waiting period under the HSR Act, the DOJ, the FTC or any U.S. state could take such action under the Antitrust Laws as it deems necessary or desirable in the public interest, including seeking to enjoin the completion of the merger or seeking divestiture of substantial assets of AIR or Tenax. Private parties may also seek to take legal action under the Antitrust Laws under certain circumstances.

There can be no assurance that a challenge to the Transactions on antitrust grounds will not be made or, if such a challenge is made, what the result will be. The required regulatory and other approvals are discussed under the section entitled “The Merger Agreement — Covenants and Agreements — Reasonable Best Efforts; Further Action” beginning on page 78 of this proxy statement/prospectus.

Accounting Treatment

The merger will be accounted for as a reverse merger using the acquisition method of accounting in accordance with Topic 805. For accounting purposes, Tenax will be treated as the accounting acquirer and AIR will be treated as the accounting acquiree. As a result, Tenax’s historical consolidated financial statements will become those of the combined company, and AIR’s identifiable assets and liabilities will be recognized at their estimated fair values as of the closing date in accordance with the acquisition method of accounting.

Dividend Policy Following the Merger

AIR has not declared or paid any cash dividends on its common stock in recent years and does not currently anticipate paying cash dividends in the foreseeable future, other than the dividend of Redemption Rights to be declared in connection with the Transactions. Any future dividends will be at the discretion of the AIR Board and will depend on AIR’s financial condition, results of operations, capital requirements and other factors the AIR Board deems relevant, and will be subject to applicable law.

Listing of the Combined Company Common Stock on NYSE American

AIR’s common stock is currently listed on NYSE American under the symbol “AIRI” and is expected to continue to be listed on NYSE American following the consummation of the merger.

THE MERGER AGREEMENT

The following section summarizes certain material provisions of the merger agreement, which is included in this proxy statement/prospectus as Annex A and is incorporated by reference herein. The summary of the merger agreement below and elsewhere in this proxy statement/prospectus is qualified in its entirety by reference to the merger agreement. This summary does not purport to be complete and may not contain all of the information about the merger agreement that is important to you. This section is not intended to provide you with any factual information about Tenax or AIR. The rights and obligations of Tenax and AIR are governed by the merger agreement and not by this summary or any other information contained in or incorporated by reference into this proxy statement/prospectus. AIR stockholders are urged to read the merger agreement carefully and in its entirety, as well as this proxy statement/prospectus and the information incorporated by reference into this proxy statement/prospectus.

Explanatory Note Regarding the Merger Agreement

The merger agreement is attached to this proxy statement/prospectus as Annex A and described in this summary to provide you with information regarding its terms. The merger agreement contains representations and warranties by AIR and Merger Sub, on the one hand, and by Tenax, on the other hand, which were made solely for the benefit of the other parties for purposes of the merger agreement. The representations, warranties and covenants made in the merger agreement by Tenax, AIR and Merger Sub were qualified and subject to important limitations agreed to by Tenax, AIR and Merger Sub in connection with negotiating the terms of the merger agreement. In particular, in your review of the representations and warranties contained in the merger agreement and described in this summary, it is important to bear in mind that the representations and warranties were negotiated with the principal purpose of allocating risk between the parties to the merger agreement, rather than establishing matters as facts about AIR or Tenax or any other person at the time they were made or otherwise. The representations and warranties may also be subject to a contractual standard of materiality different from that generally applicable to stockholders and reports and documents filed with the SEC, and some were qualified by the matters contained in the confidential disclosure letters that each of AIR and Tenax delivered in connection with the merger agreement as well as certain documents filed with the SEC. Moreover, information concerning the subject matter of the representations and warranties, which do not purport to be accurate as of the date of this proxy statement/prospectus, may have changed since February 16, 2026. Accordingly, the representations and warranties and other provisions of the merger agreement should not be read alone, but instead should be read together with the information provided elsewhere in this proxy statement/prospectus and in the documents incorporated by reference into this proxy statement/prospectus. See “Where You Can Find More Information” beginning on page 177 of this proxy statement/prospectus.

General

The merger agreement provides, among other matters, for the acquisition of Tenax pursuant to a merger, on the terms and subject to the conditions in the merger agreement and in accordance with the DLLCA. Pursuant to the merger agreement, at the effective time, Merger Sub will be merged with and into Tenax, with Tenax continuing as the surviving company and as a wholly owned subsidiary of AIR.

At the effective time, Tenax’s certificate of formation as of immediately prior to the effective time will continue to be the certificate of formation of the surviving company, and the limited liability company agreement in the form set forth in Exhibit D to the merger agreement shall be the limited liability company agreement of the surviving company. In addition, at the closing, AIR will amend its bylaws to remove the provision prohibiting stockholder action by written consent.

The parties will take all requisite action (including to the extent necessary increasing the size of the AIR Board) so that, from and after the effective time, the AIR Board will include no fewer than eight directors, which will consist only of (a) no fewer than six individuals designated by Tenax and (b) two individuals to be mutually agreed upon by Tenax and AIR, each to hold office in accordance with the articles of incorporation and bylaws of AIR. The officers of Tenax immediately prior to the effective time will be the officers of the surviving company, each until their respective successors are duly elected and qualified or until such officer’s earlier death, resignation or removal.

The closing will take place on the third business day after the satisfaction or written waiver (where permissible) of the conditions to closing (other than those conditions that by their terms are to be satisfied at the closing, but subject to the satisfaction or written waiver (where permissible) of those conditions at the closing), unless another date is agreed to in writing by Tenax and AIR.

Promptly following the receipt of the requisite AIR stockholder approvals at the special meeting, AIR will cause the amendment to AIR’s articles of incorporation to be filed with the Nevada Secretary of State in such form as required by, and executed in accordance with, the relevant provisions of the NRS and, promptly following the effectiveness of that amendment but prior to the closing, AIR will cause a certificate of change effecting the reverse stock split to be filed with the Nevada Secretary of State in accordance with NRS 78.207. As soon as practicable on the closing date, Tenax will cause a certificate of merger to be filed with the Secretary of State of the State of Delaware as provided by the DLLCA, and each of AIR, Merger Sub and Tenax will make all other filings or recordings required under the NRS or the DLLCA in connection with the merger (if any). The merger will become effective at such time as the certificate of merger is filed with the Secretary of State of the State of Delaware or at such later date and time as is specified in the certificate of merger and agreed to by AIR and Tenax in writing.

Conversion of Securities

Subject to the terms and conditions set forth in the merger agreement, at the effective time, each Tenax unit will be converted into the right to receive the portion of the merger consideration allocated in respect thereof, calculated in accordance with the capitalization schedule, which Tenax is required to deliver no less than two business days prior to the closing, and each holder of a Tenax unit immediately prior to the effective time will thereafter cease to have any rights with respect to such Tenax unit, except the right to receive the merger consideration in respect thereof. After the effective time, there will be no further registration of transfers of Tenax units.

Also at the effective time, all membership interests of Merger Sub issued and outstanding immediately prior to the effective time will be converted into 100% of the membership interests of the surviving company.

Merger Consideration

The merger consideration is defined as 126,900,000 shares of AIR common stock, to be issued to the Tenax Members and, as applicable, reserved for issuance to the Tenax Warrantholders upon the exercise of their warrants as described in the section entitled “The Merger Agreement — Covenants and Agreements — Exchange Procedures” beginning on page 66 of this proxy statement/prospectus, subject to equitable adjustment to reflect appropriately the effect of any subdivision, stock dividend, stock split (including the reverse stock split), combination, recapitalization, exchange of shares, reclassification or other like change with respect to AIR common stock occurring on or after February 16, 2026 and prior to the closing. After giving effect to the proposed amendment to the articles of incorporation of AIR contemplated by the authorized shares proposal and the subsequent reverse stock split, the merger consideration would consist of 25,380,000 shares of AIR common stock.

Exchange Procedures

At or prior to the effective time, AIR will deposit, or cause to be deposited, with Broadridge Corporate Issuer Solutions (the “Transfer Agent”), in trust for the benefit of the Tenax Members, a number of shares of AIR common stock, in book-entry or certificated form, equal to the portion of the merger consideration issuable to the Tenax Members in accordance with the capitalization schedule that Tenax is required to deliver prior to closing for the purpose of exchanging Tenax units for the merger consideration.

Prior to the effective time, Tenax will provide to each person who is or will be, as of immediately prior to the effective time, a Tenax Member a letter of transmittal, which will contain representations and warranties customary for a private placement of securities exempt from registration under the Securities Act and such other provisions as Tenax may reasonably specify (including a provision confirming that delivery shall be effected, and risk of loss and title shall pass, only upon proper delivery of such letter of transmittal). Upon delivery to the Transfer Agent of such letter of transmittal, duly executed, and such other documents as may reasonably be required by the Transfer Agent or Tenax, each Tenax Member will be entitled to receive (following the effective time), in exchange for such Tenax

66

Table of Contents

Member’s Tenax units, the portion of the merger consideration allocated to such Tenax Member in accordance with the capitalization schedule that Tenax is required to deliver prior to closing (together with cash in lieu of fractional shares), and such Tenax Member’s Tenax units will be canceled. After the effective time, any Tenax units will be deemed to represent only the right to receive the merger consideration upon such exchange.

No interest will be paid or accrue on any cash payable upon exchange of any Tenax units.

No Fractional Shares

AIR will not issue fractional shares of AIR common stock in the merger. Fractional shares of AIR common stock that would otherwise be allocable to any Tenax Members in the merger will be aggregated, and calculations will be rounded up to three decimal places. The Transfer Agent will cause the whole shares obtained thereby to be sold, in the open market or otherwise as reasonably directed by AIR, and in no case later than 20 business days after the effective time, and will make available the net proceeds thereof, on a pro rata basis, without interest and subject to the amount of any withholding taxes as contemplated in the merger agreement, as soon as practicable to the Tenax Members entitled to receive such cash.

Repayment of Payoff Debt

At the closing, Tenax or one of its affiliates will repay, or cause to be repaid, on behalf of AIR and its subsidiaries, the outstanding balance of certain indebtedness of AIR in accordance with the payoff letters furnished to Tenax. See the section entitled “The Merger Agreement — Covenants and Agreements — Payoff Letters” beginning on page 79 of this proxy statement/prospectus.

AIR Equity Awards

Each AIR Equity Award that is outstanding as of immediately prior to the effective time will continue on the same terms and conditions as were applicable to such AIR Equity Awards as of immediately prior to the effective time.

Table of Contents

Many of the representations and warranties in the merger agreement are qualified by a “materiality” or “material adverse effect” standard (that is, they will not be deemed to be untrue or incorrect unless their failure to be true or correct would be material to, or have a material adverse effect on, the applicable party).

For purposes of the merger agreement, an “AIR Material Adverse Effect” or “Tenax Material Adverse Effect” means, with respect to AIR and its subsidiaries or Tenax and its subsidiaries, respectively, any event, occurrence, state of facts, development, circumstance, change or effect that, individually or in the aggregate with all other events, occurrences, state of facts, developments, circumstances, changes and effects, (a) has had or would reasonably be expected to have a material adverse effect on the business, financial condition or results of operations of such party and its subsidiaries taken as a whole; or (b) would reasonably be expected to prevent or materially impede, materially interfere with, materially hinder or materially delay the consummation of the Transactions by such party or otherwise prevent such party from performing its obligations under the merger agreement. In addition, the definition of an “AIR Material Adverse Effect” also includes certain liquidity-related events affecting AIR, including, but not limited to, the commencement of insolvency or bankruptcy proceedings against AIR or any of its subsidiaries, or the acceleration of AIR’s material indebtedness prior to its stated maturity. However, with respect to clause (a), any event, occurrence, state of facts, development, circumstance, change or effect to the extent resulting from the following shall not be taken into account in determining whether an AIR Material Adverse Effect or Tenax Material Adverse Effect has occurred:

        any change in the market price, trading volume or credit ratings of AIR common stock or Tenax equity interests, as applicable, or any failure, in and of itself, to meet internal or public revenue or earnings projections, forecasts, guidance, estimates, milestones or budgets for any period ending (or for which revenues or earnings are released) on or after February 16, 2026 (though the facts or causes underlying or contributing to such change or failure shall be considered in determining whether an AIR Material Adverse Effect or Tenax Material Adverse Effect has occurred);

        changes in general economic, legal, regulatory or political conditions, or in the financial, credit or capital markets in general;

        changes in applicable law or GAAP, or in any interpretation thereof;

        changes in the markets or industries in which such party and its subsidiaries operate (including legal and regulatory changes);

        acts of civil unrest or war (whether or not declared), armed hostilities or terrorism or any escalation or worsening of any acts of civil unrest or war (whether or not declared), armed hostilities or terrorism under way as of February 16, 2026;

        earthquakes, hurricanes, tsunamis, tornadoes, floods, mudslides, volcanic eruptions or other natural disasters or any epidemic or pandemic;

        any changes resulting or arising from the identity of the other party or any of the other party’s affiliates; or

        the public announcement, pendency or performance of the merger agreement;

provided that, in the case of the second, third, fourth, fifth and sixth bullet points above, such party and its subsidiaries, taken as a whole, are not affected disproportionately relative to other participants in the industries in which they operate.

The representations and warranties in the merger agreement will not survive the effective time.

Additionally, between February 16, 2026 and the effective time, except as set forth in the confidential disclosure letter delivered by Tenax to AIR in connection with the merger agreement, as expressly contemplated by the merger agreement or with the prior written consent of AIR (which consent shall not be unreasonably withheld, delayed or conditioned), Tenax has agreed that it will not, and will cause each Tenax subsidiary not to:

        amend or otherwise change Tenax’s certificate of formation, limited liability company agreement or equivalent organizational documents, except for any amendments or changes that would not (i) materially delay, materially impede or prevent the consummation of the Transactions or (ii) adversely affect the AIR stockholders in any material respect differently than the Tenax Members;

        enter into any new line of business that is material to Tenax and its subsidiaries, taken as a whole; or

        authorize, commit or agree to do any of the foregoing.

No Interfering Transactions

From February 16, 2026 through the earlier of the closing and the termination of the merger agreement, neither Tenax nor AIR will, nor will permit its subsidiaries to, enter into any agreement to acquire another business or effect any transaction that is reasonably likely to prevent or impede, interfere with, hinder or delay in any material respect the consummation of the Transactions.

Stockholder Meeting

The merger agreement provides that AIR will call, give notice of, convene and hold the special meeting as promptly as reasonably practicable following the date upon which the registration statement of which this proxy statement/prospectus forms a part has been declared effective under the Securities Act, with the record date and meeting date to be set by the AIR Board after consultation with Tenax. AIR will, as promptly as reasonably practicable following the date of the merger agreement, set a record date for determining the AIR stockholders

72

Table of Contents

entitled to notice of, and to vote at, the special meeting, which record date will be at least 20 business days following the initiation of a broker search conducted pursuant to Rule 14a-13 under the Exchange Act. AIR may not change the date of, postpone or adjourn the special meeting without Tenax’s consent (not to be unreasonably withheld, conditioned or delayed), except that AIR may postpone or adjourn the special meeting no more than two times under specified circumstances, and in no event to a date more than 30 days after the date for which the special meeting was originally scheduled, without Tenax’s prior written consent. The merger agreement further provides that the AIR Board will recommend that the AIR stockholders vote in favor of the approval of the stock issuance proposal, the authorized shares proposal and the written consent proposal and will use its reasonable best efforts to solicit proxies from the AIR stockholders constituting the requisite AIR stockholder approvals.

AIR will not change the date of, postpone or adjourn the meeting without the consent of Tenax (which may not be unreasonably withheld, conditioned or delayed), except, and no more than two times, (i) for adjournments or postponements to ensure that any required supplement or amendment to this proxy statement/prospectus is provided to the AIR stockholders within a reasonable amount of time in advance of the meeting; (ii) to allow reasonable additional time to solicit proxies in favor of approval of the stock issuance proposal, the authorized shares proposal and the written consent proposal; (iii) if there are insufficient shares of AIR common stock represented at the meeting (either in person or by proxy) to constitute the necessary quorum or if AIR has not received proxies sufficient to allow the receipt of the requisite AIR stockholder approvals at the meeting; or (iv) as required by law. Tenax may cause AIR to postpone or adjourn the meeting once if AIR has not received proxies sufficient to allow the receipt of the requisite AIR stockholder approvals at the meeting and Tenax informs AIR that Tenax believes in good faith that additional time is required to solicit proxies in favor of approval of the stock issuance proposal, the authorized shares proposal and the written consent proposal.

No Solicitation by AIR

AIR has agreed that none of it or any of its subsidiaries or any of their respective representatives will, and that it will cause each of its subsidiaries and each of its and its subsidiaries’ representatives not to, directly or indirectly, (i) solicit, initiate, seek or take any other action to facilitate or encourage the making, submission or announcement of any proposal that constitutes, or could reasonably be expected to lead to, any Competing AIR Proposal; (ii) enter into, maintain, continue or participate in any discussions or negotiations with any person or entity in furtherance of, or furnish to any person any information or otherwise cooperate in any way with respect to, any Competing AIR Proposal; (iii) agree to, approve, endorse, recommend or consummate any Competing AIR Proposal; (iv) enter into, or propose to enter into, any contract or agreement which could reasonably be expected to lead to any Competing AIR Proposal; or (v) resolve, propose or agree, or authorize or permit any representative, to do any of the foregoing.

In addition, AIR has agreed to, and to cause its subsidiaries and its and its subsidiaries’ representatives to, immediately cease and cause to be terminated all existing discussions or negotiations with any persons conducted prior to the execution of the merger agreement by AIR, any of its subsidiaries or its or any of their respective representatives with respect to any Competing AIR Proposal, request the prompt return or destruction of all confidential information previously furnished and terminate access to any physical or electronic data rooms related to a potential Competing AIR Proposal previously granted to such person.

AIR will promptly, and in any event within 24 hours of AIR obtaining knowledge of the receipt thereof, advise Tenax orally and in writing of any Competing AIR Proposal or any inquiry relating to or that could reasonably be expected to lead to any Competing AIR Proposal, the financial and other material terms and conditions of any such Competing AIR Proposal or inquiry (including any changes thereto) and the identity of the person making any such Competing AIR Proposal. AIR will thereafter keep Tenax fully informed of the status and material details (including any change to the terms thereof) of any such Competing AIR Proposal or inquiry and provide to Tenax, as soon as practicable after receipt or delivery thereof (and in any event, within 24 hours of such receipt or delivery), unredacted copies of all correspondence (other than non-substantive written correspondence) and other written material (including all draft and final versions (and any amendments thereto) of agreements (including schedules and exhibits thereto) and any comments thereon) relating to any such Competing AIR Proposal or inquiry exchanged between AIR or any of its subsidiaries, on the one hand, and the person making such Competing AIR Proposal or inquiry, on the other hand.

73

Table of Contents

Notwithstanding the above, AIR may, subject to compliance with the terms of the merger agreement, furnish information to, and enter into discussions with, a person who has made, after February 16, 2026, an unsolicited, written, bona fide Competing AIR Proposal, so long as such Competing AIR Proposal did not result from a breach of the merger agreement and prior to furnishing such information and entering into such discussions, the AIR Board:

        reasonably determines, in its good faith judgment (after receiving the advice of a financial advisor of nationally recognized reputation and outside legal counsel qualified to practice in the State of Nevada and experienced in matters of Nevada corporate law) that such Competing AIR Proposal constitutes, or is reasonably likely to lead to, a Superior Proposal and the failure to furnish such information to, or enter into such discussions with, the person who made such Competing AIR Proposal would violate the AIR Board’s fiduciary duties under the NRS;

        provides such information to Tenax (or provides such information to Tenax substantially concurrent with the time it is provided to such person); and

        obtains from such person a confidentiality agreement that contains terms no less favorable to AIR than those contained in the existing confidentiality agreement between AIR and Tenax.

As used in this proxy statement/prospectus:

        the term “Competing AIR Proposal” means any inquiry, proposal or offer from any person relating to, or that would reasonably be expected to lead to, in one transaction or a series of related transactions (other than the merger), (a) any merger, consolidation, share exchange, business combination, recapitalization, liquidation, dissolution or other similar transaction involving AIR or any of its subsidiaries pursuant to which any person or the shareholders of any person would own 15% or more of any class of equity securities of AIR or of any resulting parent company of AIR; (b) any sale, lease, license, exchange, transfer or other disposition of, or joint venture involving, assets or businesses that constitute or represent more than 15% of the total revenue, operating income, EBITDA or fair market value of the assets of AIR and its subsidiaries, taken as a whole; (c) any sale, exchange, transfer or other disposition of more than 15% of any class of equity securities, or securities convertible into or exchangeable for equity securities, of AIR; (d) any tender offer or exchange offer that, if consummated, would result in any person becoming the beneficial owner of more than 15% of any class of equity securities of AIR; (e) any other transaction the consummation of which would be reasonably likely to impede, interfere with, prevent or materially delay the merger; or (f) any combination of the foregoing; and

        the term “Superior Proposal” means an unsolicited written bona fide offer made by a third party with respect to a Competing AIR Proposal (other than pursuant to clause (e) of such definition above) which the AIR Board reasonably determines, in its good-faith judgment, after having received the advice of a financial advisor of nationally recognized reputation and outside legal counsel, to be (a) more favorable to the AIR stockholders from a financial point of view (after taking into account all of the terms and conditions of such proposal, including the sources and terms of any financing, financing market conditions and the existence of a financing contingency) than the merger (after taking into account any changes to the financial terms of the merger agreement proposed by Tenax in response to such offer or otherwise) and (b) reasonably expected to be consummated on the terms so proposed. For the purposes of the definition of “Superior Proposal”, each reference to “15%” in the definition of “Competing AIR Proposal” shall be replaced with “75%”.

Change in the AIR Recommendation

The AIR Board has made the AIR Recommendation. In connection with the AIR Recommendation, the merger agreement provides that the AIR Board, or any committee thereof, may not:

        fail to make, withdraw, qualify, modify or amend, or publicly propose to fail to make, withdraw, qualify, modify or amend the AIR Recommendation;

        fail to include the AIR Recommendation in this proxy statement/prospectus;

        adopt or recommend, or propose publicly to adopt or recommend, any Competing AIR Proposal;

74

Table of Contents

        enter into any agreement relating to a Competing AIR Proposal (except as otherwise specified in the merger agreement); or

        make any public statement that is inconsistent with the AIR Recommendation.

However, prior to the receipt of the requisite AIR stockholder approvals, the AIR Board may take any of the foregoing actions (any such action, a “Change in the AIR Recommendation”) if, in response to the receipt of an unsolicited, written, bona fide Competing AIR Proposal received after February 16, 2026 or the occurrence of an Intervening Event, the AIR Board determines in its good-faith judgment (after having received the advice of a financial advisor of nationally recognized reputation and outside legal counsel qualified to practice in the State of Nevada and experienced in matters of Nevada corporate law) that its failure to make a Change in the AIR Recommendation would violate the fiduciary duties of the AIR Board under the NRS. Further, the AIR Board may not make a Change in the AIR Recommendation unless the following criteria are met:

        if the AIR Board is making a Change in the AIR Recommendation relating to a Competing AIR Proposal, such Competing AIR Proposal constitutes a Superior Proposal;

        AIR provides written notice to Tenax that the AIR Board intends to make a Change in the AIR Recommendation, specifies the reasons therefor, including a description of any Intervening Event in reasonable detail or the terms and conditions of any Superior Proposal, and includes an unredacted copy of any proposed agreement relating to such Superior Proposal;

        AIR provides a period of five business days following Tenax’s receipt of such notice during which AIR will negotiate in good faith with Tenax regarding any revisions to the terms of the merger agreement proposed by Tenax (provided that any material change regarding such Intervening Event, or any amendments to the financial terms or any other material term of such Superior Proposal will require a new notice period of three business days); and

        at the end of such notice period, the AIR Board again makes a determination in good faith after consultation with its outside legal counsel and financial advisors (and taking into account any adjustment or modification of the terms of the merger agreement proposed by Tenax) that the Competing AIR Proposal continues to be a Superior Proposal and that the Change in the AIR Recommendation is required to comply with the AIR Board’s fiduciary duties under the NRS.

As used in this proxy statement/prospectus, the term “Intervening Event” means any material event, fact, circumstance, effect, development or occurrence that (a) was not known to, or reasonably foreseeable by, the AIR Board as of February 16, 2026 or, if known, the material consequences of which were not known or reasonably foreseeable as of the date hereof and (b) does not involve or relate to the receipt, existence or terms of any Competing AIR Proposal. However, no event, fact, circumstance, effect, development or occurrence arising out of, or resulting from, the following should constitute or be taken into account in determining whether an Intervening Event has occurred:

        any Competing AIR Proposal or any actual or potential acquisition of assets or businesses from AIR or any of its subsidiaries;

        any change in the market price, trading volume or credit ratings of AIR common stock or any failure, in and of itself, to meet internal or public revenue or earnings projections, forecasts, guidance, estimates, milestones or budgets for any period ending (or for which revenues or earnings are released) on or after February 16, 2026 (provided that the facts or causes underlying or contributing to such change or failure shall be considered in determining whether an Intervening Event has occurred);

        changes in general economic, legal, regulatory or political conditions, or in the financial, credit or capital markets in general;

        changes in applicable law or GAAP, or in any interpretation thereof;

AIR has agreed to include the AIR Recommendation in this proxy statement/prospectus, unless the AIR Board makes a Change in the AIR Recommendation as permitted under the merger agreement prior to the date of distribution of this proxy statement/prospectus.

In no event will any such Change in the AIR Recommendation affect the validity and enforceability of the merger agreement or the other transaction documents, including the obligations of AIR and the AIR stockholders that are party to the transaction documents to consummate the merger or the other Transactions.

No Solicitation by Tenax

Tenax has agreed that none of it or any of its subsidiaries or any of their respective representatives will, and that it will cause each of its subsidiaries and each of its and its subsidiaries’ representatives not to, directly or indirectly, (i) solicit, initiate, seek or take any other action to facilitate or encourage the making, submission or announcement of any proposal that constitutes, or could reasonably be expected to lead to, any Competing Tenax Proposal; (ii) enter into, maintain, continue or participate in any discussions or negotiations with any person or entity in furtherance of, or furnish to any person any information or otherwise cooperate in any way with respect to, any Competing Tenax Proposal; (iii) agree to, approve, endorse, recommend or consummate any Competing Tenax Proposal; (iv) enter into, or propose to enter into, any contract or agreement which could reasonably be expected to lead to any Competing Tenax Proposal; or (v) resolve, propose or agree, or authorize or permit any representative, to do any of the foregoing.

In addition, Tenax has agreed to, and to cause its subsidiaries and its and its subsidiaries’ representatives to, immediately cease and cause to be terminated all existing discussions or negotiations with any persons conducted prior to the execution of the merger agreement by Tenax, any of its subsidiaries or its or any of their respective representatives with respect to any Competing Tenax Proposal, request the prompt return or destruction of all confidential information previously furnished and terminate access to any physical or electronic data rooms related to a potential Competing Tenax Proposal previously granted to such person.

Tenax will promptly, and in any event within 24 hours of Tenax obtaining knowledge of the receipt thereof, advise AIR orally and in writing of any Competing Tenax Proposal or any inquiry relating to or that could reasonably be expected to lead to any Competing Tenax Proposal, the financial and other material terms and conditions of any such Competing Tenax Proposal or inquiry (including any changes thereto) and the identity of the person making any such Competing Tenax Proposal. Tenax will thereafter keep AIR fully informed of the status and material details (including any change to the terms thereof) of any such Competing Tenax Proposal or inquiry and provide to AIR, as soon as practicable after receipt or delivery thereof (and in any event, within 24 hours of such receipt or delivery), unredacted copies of all correspondence (other than non-substantive written correspondence) and other written material (including all draft and final versions (and any amendments thereto) of agreements (including schedules and exhibits thereto) and any comments thereon) relating to any such Competing Tenax Proposal or inquiry exchanged between Tenax or any of its subsidiaries, on the one hand, and the person making such Competing Tenax Proposal or inquiry, on the other hand.

Notwithstanding the above, Tenax may, subject to compliance with the terms of the merger agreement, furnish information to, and enter into discussions with, a person who has made, after February 16, 2026, an unsolicited, written, bona fide Competing Tenax Proposal, so long as such Competing Tenax Proposal did not result from a breach of the merger agreement and, prior to furnishing such information and entering into such discussions, the Tenax Board obtains from such person a confidentiality agreement that contains terms no less favorable to Tenax than those contained in the existing confidentiality agreement between AIR and Tenax.

Access to Information

Tenax has agreed to provide to AIR and its representatives reasonable access during normal business hours upon reasonable prior notice to Tenax’s personnel and records on a basis consistent with AIR’s access to such personnel and records prior to February 16, 2026.

Employee Matters

For one year following the effective time, AIR will, or will cause its subsidiaries to, provide each employee of AIR or its subsidiaries, as of immediately prior to the effective time, who continues to be employed by AIR or the surviving company after the closing date with (i) a base salary or wage rate, as applicable, and annual cash target bonus opportunity that is not less than the base salary or wage rate, as applicable, and annual cash target bonus opportunity provided to such employee immediately prior to the effective time and (ii) other employee benefits (including severance benefits) that are no less favorable in the aggregate than either, as determined by AIR in its sole discretion, (A) those provided by AIR and its subsidiaries immediately prior to the effective time or (B) those provided by Tenax to similarly situated employees immediately prior to the effective time. Notwithstanding anything to the contrary in the merger agreement, the terms and conditions of employment for any employee of AIR or its subsidiaries covered by any of AIR’s collective bargaining agreements will continue to be governed by such collective bargaining agreement.

The merger agreement provides that the foregoing employee matters provisions are solely for the benefit of the parties to the merger agreement, no third party has any rights under such provisions and such provisions do not (i) amend any compensation or benefit plan, program, policy, agreement or arrangement; (ii) obligate AIR or the surviving company or any of their respective subsidiaries to maintain any benefit plan or arrangement or retain the employment of any particular employee; or (iii) prevent AIR or the surviving company or any of their respective subsidiaries from amending or terminating any plan or arrangement (in each case, other than as provided in such provisions).

Directors’ and Officers’ Indemnification and Insurance

AIR has agreed to cause the surviving company, to the fullest extent permitted by the NRS, to honor all rights to indemnification and exculpation from liabilities, including advancement of expenses, existing in favor of the current or former directors or officers of AIR or its subsidiaries at or prior to the effective time for acts or omissions occurring at or prior to the effective time, as such indemnification provisions are provided for in the articles of incorporation and bylaws of AIR or indemnification agreements between AIR and such individuals. Such obligations will survive the Transactions in full force and effect in accordance with their terms.

Table of Contents

Subject to certain limitations, AIR will maintain, for the three-year period commencing immediately after the effective time, a directors’ and officers’ liability insurance policy with an insurance carrier with the same or better credit rating as AIR’s insurance carrier as of February 16, 2026 covering acts or omissions occurring at or prior to the effective time with respect to those individuals who are currently (and any individuals who prior to the effective time become) covered by AIR’s directors’ and officers’ liability insurance policies, on terms, conditions, retentions and limits of liability that are at least as favorable as AIR’s existing policies in effect on February 16, 2026. AIR will be permitted, prior to the effective time, to obtain and fully pay the premium for the extension of (i) the directors’ and officers’ liability coverage of AIR’s existing directors’ and officers’ insurance policies and (ii) AIR’s existing fiduciary liability insurance policies, in each case for a claims reporting period or discovery period of three years from the effective time, which will be from an insurance carrier with the same or better credit rating as AIR’s insurance carrier as of February 16, 2026, with terms, conditions, retentions and limits of liability that are at least as favorable as AIR’s existing policies in effect on February 16, 2026; provided, however, that in no event shall Tenax or AIR be required to expend for any policies an aggregate amount in excess of 300% of the annual premiums currently paid by AIR for such insurance.

In the event that AIR or any of its successors or assigns (i) consolidates with or merges into any other person and ceases to be the continuing or surviving corporation or entity of such consolidation or merger or (ii) transfers all or substantially all of its properties and assets to any person, then, and in each such case, the surviving company will ensure that AIR will assume the obligations described above.

Reasonable Best Efforts; Further Action

Subject to the terms and conditions of the merger agreement, each party has agreed to use its reasonable best efforts to take, or cause to be taken, all actions that are necessary, proper or advisable to consummate and make effective the Transactions, including using its reasonable best efforts to accomplish the following:

        the satisfaction of the conditions precedent to the merger;

        the obtaining of all necessary actions or nonactions and consents from, and the giving of any necessary notices to, governmental authorities and the making of all necessary registrations, declarations and filings (including registrations, declarations and filings with, or notices to, governmental authorities that may be required or advisable under the Antitrust Laws, if any);

        the taking of all reasonable steps to provide any supplemental information requested by any governmental authority, including participating in meetings with officials of such entity in the course of its review of the merger agreement or the Transactions;

        the taking of all reasonable steps as may be necessary to avoid any action by any governmental authority or third party that would otherwise have the effect of materially delaying or preventing the consummation of the merger; and

        the defending or contesting of any actions challenging the merger agreement or the consummation of the merger, including seeking to have any stay or temporary restraining order entered by any court or other governmental authority vacated or reversed.

Each of AIR and the AIR Board will take all actions necessary to ensure that the Transactions will be consummated as promptly as practicable if any state takeover statute or similar statute or regulation is or becomes applicable to the merger agreement and to minimize the effect of such statute or regulation on the merger agreement and the Transactions. However, in no event will Tenax or its affiliates, including AIR, be required to agree to or accept (i) any prohibition of or limitation on its or their ownership, or any limitation that would affect its or their operation, of any portion of their respective businesses or assets, including after giving effect to the Transactions; (ii) any commitment, undertaking or order to divest, hold separate or otherwise dispose of any portion of its or their respective businesses or assets, including after giving effect to the Transactions; (iii) any limitation on the ability of the Tenax Members to acquire or hold or exercise full rights of ownership of any capital stock of AIR or its subsidiaries, including after giving effect to the Transactions; or (iv) any other limitation on its or their ability to, or the manner in which they, operate, conduct or control their respective businesses or operations, including after giving effect to the Transactions.

Pursuant to the merger agreement, Tenax will determine and direct the strategy and process by which the parties will seek required approvals relating to Antitrust Laws. Tenax and AIR have agreed that neither party will make any filings, submissions or substantive written communications to any governmental authority to obtain consents to the merger under Antitrust Laws without first providing a written copy of such filing, submission or communication to the other party (or as appropriate to such party’s outside counsel) and allowing the other party a reasonable opportunity to provide comments on such filing, submission or communication prior to submission. Tenax and AIR have agreed to incorporate all reasonable comments of the other party (or as appropriate such party’s outside counsel) with respect to such filings, submissions and communications prior to delivery of the same to any governmental authority.

Payoff Letters

AIR will deliver to Tenax at or prior to the closing executed payoff letters in customary form reasonably satisfactory to Tenax in respect of certain indebtedness of AIR, which shall indicate the total amount required to be paid to fully satisfy all principal, interest, prepayment premiums, penalties, breakage costs or similar obligations under such indebtedness and state that upon receipt of such amount, the applicable indebtedness and instruments evidencing such indebtedness shall be terminated. Further, AIR will make arrangements for the holders of such indebtedness to deliver to Tenax at or as soon as practicable after the closing all possessory collateral then in its possession and all lien release documents and filings with respect to all liens in or upon the assets or properties of AIR and its subsidiaries securing such indebtedness.

Stockholder Litigation

The merger agreement requires that AIR, orally and in writing, provide Tenax with prompt notice of any litigation commenced or, to AIR’s knowledge, threatened against AIR and/or its directors or executive officers relating to the merger agreement, the merger or the other Transactions, and that AIR keep Tenax promptly and reasonably informed regarding any such litigation. AIR has agreed to give Tenax the opportunity to participate in the defense or settlement of any such litigation and shall give due consideration to Tenax’s views with respect thereto. Further, AIR may not agree to any settlement of any such litigation without Tenax’s prior written consent (such consent not to be unreasonably withheld, conditioned or delayed).

AIR Charter Amendment and Reverse Stock Split

Assuming, and promptly following the receipt of the approval of the authorized shares proposal at the special meeting of AIR stockholders, AIR will cause the related amendment to AIR’s articles of incorporation to be filed with the Nevada Secretary of State in such form as required by, and executed in accordance with, the relevant provisions of the NRS. Following the effectiveness of that amendment but prior to the closing, AIR will cause a certificate of change to be filed with the Nevada Secretary of State to effect the reverse stock split in accordance with NRS 78.207.

Redemption Rights Agreement

The following is a summary of the material provisions of the redemption rights agreement to be entered into by AIR and the Rights Agent and is qualified in its entirety by reference to the full text of the form of such redemption rights agreement attached as Annex C to this proxy statement/prospectus and incorporated by reference into this proxy statement/prospectus.

Prior to the closing, AIR will enter into a redemption rights agreement with the Rights Agent that will govern the exercise of Redemption Rights by certain eligible AIR stockholders. Prior to the closing, AIR will declare and issue, as a dividend to AIR stockholders as of the trading day immediately preceding the closing date (the “Rights Record Date”), a right to cause AIR to redeem shares of AIR common stock that such AIR stockholders then own and continue to own on the first anniversary of the closing. The Redemption Rights will entitle the holders thereof to require AIR to purchase all or a portion of such AIR stockholder’s shares of AIR common stock for a redemption price, payable in cash, equal to 107.3% of the Debt Adjusted AIR Share Price, if the volume weighted average price of AIR common stock during the 20 trading days preceding the first anniversary of the closing is lower than 107.3% of the Debt Adjusted AIR Share Price.

As of and after the Rights Record Date, the Redemption Rights will be evidenced solely by certificates (“Rights Certificates”) evidencing one Redemption Right for each share of AIR common stock owned as of the close of business on the Rights Record Date. As soon as practicable after the Rights Record Date, the Rights Agent will cause to be delivered to each beneficial owner of AIR common stock one or more Rights Certificates evidencing one Redemption Right for each share of AIR common stock owned as of the close of business on the Rights Record Date. The Redemption Rights and the Rights Certificates may not be sold, assigned or transferred, in whole or in part, in any manner. Any Redemption Right held by an AIR stockholder will automatically cease to exist upon any transfer, sale or assignment of beneficial ownership of the share of AIR common stock to which such Redemption Right relates.

To be eligible to exercise the Redemption Rights, an AIR stockholder must have been a beneficial owner of shares of AIR common stock as of the close of business on the Rights Record Date and must have remained continuously a beneficial owner of such shares of AIR common stock to be redeemed from the Rights Record Date until the expiration of the redemption period. An AIR stockholder who sells and repurchases shares of AIR common stock during such period will not be permitted to exercise the Redemption Rights with respect to such shares. Following the conclusion of the 20-trading-day measurement period ending on (and including) the trading day immediately preceding the first anniversary of the closing, AIR will, not later than the second business day after the end of such measurement period, provide written notice to each eligible AIR stockholder of the volume weighted average price of AIR common stock during such measurement period. If such volume weighted average price, rounded to the nearest cent, is lower than the redemption price (which will be equal to 107.3% of the Debt Adjusted AIR Share Price), such notice will confirm that the Redemption Rights may be exercised prior to the expiration time. If such volume weighted average price is equal to or in excess of the redemption price, such notice will state that the Redemption Rights may not be exercised and have expired and that AIR has terminated the redemption rights agreement.

The Redemption Rights will be exercisable during a period of 10 consecutive trading days commencing on the trading day immediately following the first anniversary of the closing. Any Redemption Rights not exercised prior to the expiration of such redemption period will automatically terminate and be of no further force or effect. To exercise the Redemption Rights, an eligible AIR stockholder must deliver to the Rights Agent and AIR a written notice of redemption, together with the relevant rights certificate and, to the extent such shares are certificated, the certificates representing the shares to be redeemed, duly endorsed for transfer to AIR, and any other certifications or supporting information requested by AIR to support that such stockholder is in fact an eligible AIR stockholder of such shares of AIR common stock to be redeemed from the Rights Record Date until the expiration of the redemption period. Not later than the business day immediately following the expiration of the redemption period, the Rights Agent will provide AIR with a detailed list of the names of the AIR stockholders who have submitted valid notices of redemption and the number of shares to be redeemed from such stockholders in accordance with such notices of redemption, together with copies thereof. Within two business days following receipt of such information, AIR will deposit with the Rights Agent by wire transfer of immediately available funds an amount sufficient to pay the redemption price for all shares duly submitted for redemption. The Rights Agent will thereupon

cause an amount in cash representing the aggregate redemption price for the shares redeemed by each eligible AIR stockholder to be delivered to or upon the order of such AIR stockholder not later than five business days after the expiration time.

If, after the Rights Record Date but prior to the first anniversary of the closing, AIR pays a share dividend or otherwise makes a distribution on its common stock payable in AIR common stock, subdivides the outstanding AIR common stock into a larger number of shares, combines the outstanding AIR common stock into a smaller number of shares or issues by reclassification of AIR common stock any shares of AIR common stock, then the redemption price will be proportionally adjusted such that, upon exercise of all of the Redemption Rights, the aggregate redemption prices with respect to all eligible shares will remain unchanged. If, after the Rights Record Date but prior to the first anniversary of the closing, AIR consummates any merger or sale of AIR (whether by merger, sale of shares or all or substantially all of AIR’s assets or otherwise), then no adjustment will be made to the number of shares associated with the Redemption Rights or the redemption price as a result of such fundamental transaction. In such event, an AIR stockholder who exercises the Redemption Rights with respect to such AIR stockholder’s shares will not be entitled to receive any shares, securities, cash or other property in respect of such shares to which holders of AIR common stock would otherwise be entitled as a result of such fundamental transaction. An AIR stockholder who does not exercise the Redemption Rights with respect to such AIR stockholder’s shares will remain entitled to receive any shares, securities, cash or other property to which holders of AIR common stock are entitled as a result of such fundamental transaction.

The redemption rights agreement will automatically terminate and be of no further force or effect on the date that is five business days after the expiration of the redemption period, provided that all disputes with respect to amounts payable to the AIR stockholders have been resolved and AIR has paid or caused to be paid or deposited with the Rights Agent all amounts payable to the AIR stockholders under the redemption rights agreement.

Registration Rights Agreement

The following is a summary of the material provisions of the registration rights agreement to be entered into by AIR, the Tenax Members, the Tenax Warrantholders and NTC Group and is qualified in its entirety by reference to the full text of the form of such registration rights agreement attached as Annex D to this proxy statement/prospectus and incorporated by reference into this proxy statement/prospectus.

At the closing, AIR, the Tenax Members, the Tenax Warrantholders and NTC Group, as Investors’ Representative, will enter into the registration rights agreement. The securities entitled to registration rights under the registration rights agreement consist of (a) shares of AIR common stock issued to the Tenax Members pursuant to the merger agreement, (b) shares of AIR common stock issuable upon exercise of the warrants held by the Tenax Warrantholders and (c) any other equity securities received with respect to or on account of the foregoing (collectively, the “Registrable Securities”), in each case subject to customary fall-away provisions.

Under the registration rights agreement, certain key holders (including NEH, Thomas Foley, Taran Bakker and their controlled affiliates and permitted transferees) have customary demand rights to require AIR to effect public offerings of Registrable Securities, including underwritten offerings, subject to certain limitations, including a minimum aggregate value threshold of $40,000,000 per offering (unless a lesser amount is then held by the demanding stockholder) and a limit of one underwritten offering in any 90-day period. The registration rights agreement also provides the Tenax Members and Tenax Warrantholders with customary “piggyback” registration rights, subject to customary withdrawal and cutback provisions.

These registration rights are subject to certain conditions and limitations, including AIR’s right to defer or suspend a registration statement during limited deferral periods for specified purposes, subject to an aggregate limit of one deferral period in any 12-month period not to exceed 90 days. AIR has agreed to be responsible for all offering expenses incurred in connection with the registration of the Registrable Securities, other than underwriting discounts and commissions, transfer taxes and certain underwriter fees not customarily paid by issuers. The parties to the registration rights agreement will provide each other customary indemnifications.

AIR Stockholder Support Agreement

The following is a summary of the material provisions of the AIR Stockholder Support Agreement and is qualified in its entirety by reference to the full text of the form of the AIR Stockholder Support Agreement, which is included as Exhibit A to the merger agreement attached as Annex A to this proxy statement/prospectus.

In connection with the execution of the original merger agreement, on February 16, 2026, certain directors and significant stockholders of AIR, referred to as the Key AIR Stockholders, entered into the AIR Stockholder Support Agreement with Tenax, pursuant to which the Key AIR Stockholders agreed, among other things, to vote their shares of AIR common stock in favor of the authorized shares proposal, the written consent proposal and the stock issuance proposal and against any competing proposal. The AIR Stockholder Support Agreement, which by its terms operates with reference to the merger agreement as amended from time to time, remains in full force and effect and was not amended in connection with the amendment and restatement of the merger agreement. As of [•], 2026, the record date for the special meeting, the Key AIR Stockholders beneficially owned, in the aggregate, shares of AIR common stock representing approximately [•]% of the voting power of the outstanding shares of AIR common stock entitled to vote at the special meeting. For information regarding the shares of AIR common stock beneficially owned by each Key AIR Stockholder, see the section entitled “Principal Holders of AIR Common Stock” beginning on page 171 of this proxy statement/prospectus.

Pursuant to the AIR Stockholder Support Agreement, each Key AIR Stockholder has agreed, from the date of the agreement until the earlier of the effective time and the termination of the merger agreement in accordance with its terms, among other things, to (i) vote, or cause to be voted, all shares of AIR common stock beneficially owned by such Key AIR Stockholder in favor of the authorized shares proposal, the written consent proposal and the stock issuance proposal and against any Competing AIR Proposal or any other action that would reasonably be expected to impede, interfere with, delay or prevent the consummation of the merger; (ii) not transfer or encumber such shares, subject to limited exceptions; and (iii) not solicit, initiate or participate in discussions regarding, or approve or enter into, any Competing AIR Proposal. Each Key AIR Stockholder has also agreed not to commence or join in, and to take all reasonable actions necessary to opt out of, any action against AIR or its directors and officers relating to the merger agreement or the Transactions, and has granted Tenax an irrevocable proxy to vote such Key AIR Stockholder’s shares in a manner consistent with the agreement solely with respect to the matters described above. In addition, each Key AIR Stockholder has irrevocably waived any and all notice, information and consent requirements and any rights of first refusal, rights of first offer, redemption rights, co-sale rights, registration rights, preemptive rights and any dissenter’s or appraisal rights that may be applicable to, or triggered by, the Transactions. The Key AIR Stockholders have delivered the AIR Stockholder Support Agreement to Tenax, and each Key AIR Stockholder is entering into the agreement solely in its capacity as a beneficial owner of shares of AIR common stock and not in any capacity as a director or officer of AIR. The AIR Stockholder Support Agreement is governed by Nevada law.

Tenax Member Support Agreement

The following is a summary of the material provisions of the Tenax Member Support Agreement and is qualified in its entirety by reference to the full text of the form of the Tenax Member Support Agreement, which is included as Exhibit B to the merger agreement attached as Annex A to this proxy statement/prospectus.

In connection with the execution of the merger agreement, Tenax, AIR and NEH, as the sole consenting member party thereto, entered into an amended and restated Tenax Member Support Agreement, dated as of July 2, 2026, which amended and restated the Tenax Member Support Agreement entered into in connection with the execution of the original merger agreement. NEH is the record and beneficial owner of 6,570,000 Class A-1 units of Tenax, representing approximately 79.81% of the outstanding Tenax units on a fully diluted basis and approximately 85.38% of the voting power of the outstanding Tenax units.

Pursuant to the Tenax Member Support Agreement, NEH, acting without a meeting in accordance with Section 404 of the DLLCA, irrevocably consented to, approved and adopted, in all respects, the merger, the merger agreement and the other transaction documents and the Transactions, including the distribution of the merger consideration in accordance with the Tenax closing capitalization schedule, and agreed that it will not revoke, rescind or otherwise modify its written consent. This written consent constituted the approval of the merger by holders of a majority in voting power of the issued and outstanding membership units of Tenax required under the merger agreement. Accordingly, the Tenax member approval condition to the completion of the merger has been satisfied, and no meeting of the Tenax Members will be held in connection with the merger.

87

Table of Contents

The Tenax Member Support Agreement also provides that, until the earlier of the effective time and the termination of the merger agreement in accordance with its terms, NEH will not transfer or encumber its Tenax units (other than to certain permitted transferees that execute a joinder to the Tenax Member Support Agreement), will not, and will cause its controlled affiliates not to, solicit, participate in discussions or negotiations regarding, or approve, endorse or enter into any agreement with respect to, any Competing Tenax Proposal, and will not commence or join in, and will take all reasonable actions necessary to opt out of, any action against Tenax or its managers and officers relating to the merger agreement or the Transactions, including any claim challenging the validity of the merger agreement or alleging a breach of fiduciary duty in connection therewith. NEH has also waived any and all notice, information and consent requirements, as well as any right of first refusal, right of first offer, right of first negotiation, rights restricting share transfers, redemption rights, co-sale rights, registration rights, preemptive rights and other similar rights that may be applicable to, or triggered by, the Transactions, whether contained in AIR’s organizational documents, in any contractual obligation between AIR and NEH or under applicable law. The Tenax Member Support Agreement is governed by Nevada law.

Lock-Up Agreements

The following is a summary of the material provisions of the Lock-Up Agreements and is qualified in its entirety by reference to the full text of the form of Tenax Member Lock-Up Agreement, which is included as Exhibit C to the merger agreement attached as Annex A to this proxy statement/prospectus.

In connection with the execution of the original merger agreement, on February 16, 2026, each of Thomas Foley, Chairman of Tenax, and Taran Bakker, a director of Tenax, entered into a lock-up agreement with AIR (together, the “Lock-Up Agreements”). Pursuant to the Lock-Up Agreements, and subject to certain exceptions, without the prior written consent of AIR, Mr. Foley and Mr. Bakker have each agreed not to offer, sell, pledge, transfer or otherwise dispose of, or enter into any hedging or similar transaction with respect to, any shares of AIR common stock or securities convertible into or exercisable or exchangeable for AIR common stock held directly or indirectly by them, during the period commencing upon the closing and ending on the date that is 180 days after the closing date. The permitted exceptions include specified transfers by gift, for estate-planning purposes, by will or intestacy and to affiliates and other related transferees, in each case subject to the transferee agreeing to be bound by the restrictions in the Lock-Up Agreements. The shares of AIR common stock subject to the Lock-Up Agreements will not constitute unrestricted publicly-held shares for purposes of the NYSE American initial listing requirements during the restricted period. See the section entitled “Risk Factors — Risks Relating to the Merger — If the combined company fails to comply with the initial listing requirements of the NYSE American, shares of AIR common stock could face possible delisting, which would result in, among other things, a limited public market for shares of AIR common stock and make obtaining future debt or equity financing more difficult for us.” beginning on page 24 of this proxy statement/prospectus.

MATERIAL U.S. FEDERAL INCOME TAX CONSEQUENCES OF THE TRANSACTIONS

The following discussion is the opinion of Ellenoff Grossman & Schole LLP and is based on the material U.S. federal income tax consequences to holders of AIR common stock with respect to (i) the Transactions and (ii) the post-Transactions ownership and disposition of AIR common stock. This summary applies only to holders of AIR common stock that hold such stock as capital assets for U.S. federal income tax purposes (generally, property held for investment). This summary is general in nature and does not constitute tax advice. This summary does not discuss all aspects of U.S. federal income taxation that might be relevant to a particular holder of AIR common stock in light of such holder’s individual circumstances or status, nor does it address tax consequences applicable to holders of AIR common stock subject to special rules, such as:

        dealers in securities or foreign currency;

        broker-dealers;

        traders in securities that elect to use a mark-to-market method of accounting;

        tax-exempt organizations;

        financial institutions, banks or trusts;

        mutual funds;

        life insurance companies, real estate investment trusts and regulated investment companies;

        holders that actually or constructively own 10% or more of AIR’s common stock;

        holders that hold AIR common stock as part of a hedge, straddle, constructive sale, conversion transaction or other integrated investment;

        holders that have a functional currency other than the U.S. dollar;

        holders that received AIR common stock through the exercise of employee stock options, through a tax-qualified retirement plan or otherwise as compensation;

        U.S. expatriates;

        controlled foreign corporations;

        persons subject to special tax accounting rules as a result of any item of gross income with respect to AIR common stock being taken into account in an “applicable financial statement” (as defined in the Code);

        passive foreign investment companies; or

        pass-through entities or investors in pass-through entities.

This summary is based on the Code, applicable U.S. Department of Treasury (the “Treasury”) regulations thereunder, and judicial and administrative interpretations thereof, all as in effect as of the date of this proxy statement/prospectus, and all of which may change, possibly with retroactive effect. Any such change could affect the conclusions discussed below. Consummation of the Transactions is not conditioned on the receipt of any tax opinion with respect to the tax treatment of holders of AIR common stock. Furthermore, no assurance can be given that the IRS will agree with this discussion or that, if the IRS were to take a contrary position, such position ultimately would not be sustained by the courts.

This summary does not address U.S. federal taxes other than those pertaining to U.S. federal income taxation (such as estate or gift taxes, the alternative minimum tax or the Medicare tax on investment income), nor does it address any aspects of U.S. state or local or non-U.S. taxation.

ALL HOLDERS ARE URGED TO CONSULT THEIR OWN TAX ADVISORS REGARDING THE TAX CONSEQUENCES OF THE TRANSACTIONS AND OTHER EVENTS DESCRIBED BELOW, INCLUDING THE EFFECTS OF U.S. FEDERAL, STATE AND LOCAL AND NON-U.S. TAX LAWS.

89

Table of Contents

U.S. Holders

For purposes of this summary, a “U.S. Holder” means a beneficial owner of AIR common stock that is, for U.S. federal income tax purposes:

        an individual who is a citizen or resident of the United States;

        a corporation (or other entity that is treated as a corporation for U.S. federal income tax purposes) organized in or under the laws of the United States, any state therein or the District of Columbia;

        an estate the income of which is includible in gross income for U.S. federal income tax purposes regardless of its source; or

        a trust (i) that is subject to the primary supervision of a court within the United States and all substantial decisions of which are controlled by one or more United States persons (within the meaning of Section 7701(a)(30) of the Code) or (ii) that has a valid election in effect under applicable Treasury regulations to be treated as a United States person.

If a partnership (or any entity or arrangement characterized as a partnership for U.S. federal income tax purposes) holds AIR common stock, the tax treatment of such partnership and any person treated as a partner of such partnership will generally depend on the status of the partner and the activities of the partnership. Partnerships that hold AIR common stock and persons that are treated as partners of such partnerships should consult their own tax advisors about the particular U.S. federal income tax consequences to them of the Transactions and the post-Transactions ownership and disposition of AIR common stock.

Redemption Rights

Receipt of Redemption Rights.    There is substantial uncertainty about the U.S. federal income tax treatment of the Redemption Rights. Specifically, there is no authority addressing whether the Redemption Rights should be treated as a distribution of property with respect to AIR common stock or an “open transaction”. Such determination is factual in nature. Based on the specific characteristics of the Redemption Rights, and unless otherwise required by a change in law after the date of the redemption rights agreement, we intend to take the position that a U.S. Holder’s receipt of the Redemption Rights constitutes an “open transaction” for U.S. federal income tax purposes. If our reporting position is correct, a U.S. Holder generally will not recognize income in respect of the Redemption Rights on the date of issuance and will not take tax basis in the Redemption Rights. However, the IRS could assert that the issuance of the Redemption Rights should be treated as a “closed transaction” (e.g., as the payment of a dividend or of a fee) for U.S. federal income tax purposes. U.S. Holders should consult their tax advisors about the U.S. federal income tax treatment of the Redemption Rights.

Exercise of Redemption Rights.    The redemption of a U.S. Holder’s AIR common stock that is effected by such U.S. Holder’s exercise of the Redemption Rights pursuant to the terms of the redemption rights agreement generally will be treated as a sale of such U.S. Holder’s AIR common stock. As a result, a U.S. Holder will recognize gain or loss equal to the difference between the amount of cash received by such U.S. Holder and such U.S. Holder’s tax basis in the AIR common stock redeemed. Gain or loss will be capital gain or loss and will be long-term capital gain or loss if the redeemed AIR common stock was held more than one year.

It is possible that the redemption of a U.S. Holder’s AIR common stock that is effected by such U.S. Holder’s exercise of the Redemption Rights pursuant to the terms of the redemption rights agreement will be treated as a distribution by AIR to such U.S. Holder. The full amount of cash received by the U.S. Holder for redeemed AIR common stock (without any offset for such U.S. Holder’s tax basis in the stock) will be treated as a dividend to the extent of AIR’s current and accumulated earnings and profits allocable to the distribution. A U.S. Holder’s tax basis in redeemed AIR common stock will be added to the tax basis of such U.S. Holder’s remaining AIR common stock. For non-corporate U.S. Holders, such dividends may be “qualified dividend income” that is taxed at the lower applicable capital gains rate if certain conditions, including holding period requirements, are satisfied. Any period during which a U.S. Holder owns AIR common stock and Redemption Rights will be excluded from the U.S. Holder’s holding period for purposes of determining whether a dividend is “qualified dividend income”.

90

Table of Contents

To the extent cash received by a U.S. Holder exceeds such U.S. Holder’s allocable share of AIR’s current and accumulated earnings and profits, the distribution will first be treated as a non-taxable return of capital that reduces such U.S. Holder’s adjusted basis in their AIR common stock. Any amounts in excess of such U.S. Holder’s adjusted basis will be treated as capital gain. AIR will notify U.S. Holders publicly if a redemption is expected to be treated as a distribution.

U.S. Holders should consult their own tax advisors about the tax treatment of exercising their Redemption Rights.

The Merger

U.S. Holders will retain their AIR common stock in the merger. Accordingly, U.S. Holders will not recognize gain or loss for U.S. federal income tax purposes as a result of the merger, and a U.S. Holder’s holding period in their AIR common stock will remain unchanged.

Non-U.S. Holders

For purposes of this summary, a “non-U.S. Holder” means a beneficial owner of AIR common stock that is, for U.S. federal income tax purposes, neither a U.S. Holder nor an entity or arrangement classified as a partnership for U.S. federal income tax purposes.

Redemption Rights

Receipt of Redemption Rights.    As discussed above in the section entitled “— U.S. Holders — Redemption Rights — Receipt of Redemption Rights”, we intend to take the position that a non-U.S. Holder’s receipt of the Redemption Rights constitutes an “open transaction” for U.S. federal income tax purposes. If our reporting position is correct, a non-U.S. Holder generally will not recognize income in respect of the Redemption Rights on the date of issuance and will not take tax basis in the Redemption Rights. However, the IRS could assert that the issuance of the Redemption Rights should be treated as a “closed transaction” (e.g., as the payment of a dividend or of a fee) for U.S. federal income tax purposes. Non-U.S. Holders should consult their tax advisors about the U.S. federal income tax treatment of the Redemption Rights.

Exercise of Redemption Rights.    As discussed above in the section entitled “— U.S. Holders — Redemption Rights — Exercise of Redemption Rights”, the redemption of a non-U.S. Holder’s AIR common stock that is effected by such non-U.S. Holder’s exercise of the Redemption Rights pursuant to the terms of the redemption rights agreement generally will be treated as a sale of such non-U.S. Holder’s AIR common stock. As a result, a non-U.S. Holder generally will not be subject to U.S. federal income taxation as a result of the redemption unless:

(a)     such gain is effectively connected with the conduct by such non-U.S. Holder of a trade or business in the United States (and, if an income tax treaty applies, the gain is attributable to a U.S. permanent establishment maintained by such non-U.S. Holder);

(b)    in the case of gain realized by a non-U.S. Holder who is an individual, such non-U.S. Holder is present in the United States for 183 days or more in the taxable year of the redemption and certain other conditions are met; or

(c)     AIR common stock constitutes “United States real property holding interests” by reason of AIR’s status as a “United States real property holding corporation” (“USRPHC”) for U.S. federal income tax purposes at any time within the shorter of (i) the five-year period preceding the redemption of such non-U.S. Holder’s AIR common stock and (ii) such non-U.S. Holder’s holding period for their AIR common stock.

A non-U.S. Holder whose gain is described in clause (a) above generally will be subject to U.S. federal income tax on such gain in the same manner as a U.S. Holder as described above in the section entitled “— U.S. Holders — Redemption Rights — Exercise of Redemption Rights”. In addition, a non-U.S. Holder that is a foreign corporation may be subject to a branch profits tax at a 30% rate, or lower rate specified in an applicable income tax treaty.

91

Table of Contents

A non-U.S. Holder whose gain is described in clause (b) above generally will be subject to U.S. federal income tax on such gain at a rate of 30%, or a lower rate specified in an applicable income tax treaty. Such gain may be offset by certain U.S.-source capital losses, even though such non-U.S. Holder is not considered a resident of the United States.

With respect to clause (c) above, we believe that we are not currently a USRPHC. The determination of whether we are a USRPHC depends on the fair market value of our United States real property interests relative to the fair market value of our other trade or business assets and our non-U.S. real property interests. If we were or are a USRPHC, non-U.S. Holders generally will be subject to U.S. federal income tax in the same manner as U.S. Holders.

If the redemption is treated as a dividend, the treatment of a non-U.S. Holder’s receipt of cash will be determined in the manner described above in the section entitled “— U.S. Holders — Redemption Rights — Exercise of Redemption Rights”. To the extent amounts received by a non-U.S. Holder are treated as dividends, such dividends generally will be subject to U.S. federal withholding tax at a rate of 30%, or a lower rate specified in an applicable income tax treaty. Non-U.S. Holders should consult their tax advisors about their entitlement to, and the procedure for obtaining, benefits under an applicable income tax treaty.

The Merger

Non-U.S. Holders will retain their AIR common stock in the merger. Accordingly, non-U.S. Holders will not recognize gain or loss for U.S. federal income tax purposes as a result of the merger, and a non-U.S. Holder’s holding period in their AIR common stock will remain unchanged.

Information Reporting and Backup Withholding

The issuance of the Redemption Rights and payments made to redeem AIR common stock pursuant to the exercise of the Redemption Rights may be subject to information reporting and backup withholding at a rate of 24% if a Holder (i) fails to provide a valid taxpayer identification number and does not comply with certain certification procedures or (ii) does not otherwise establish an exemption. Backup withholding is not an additional tax. Rather, any amounts withheld may be credited against a Holder’s U.S. federal income tax liability. If backup withholding results in an overpayment of taxes, a Holder may obtain a refund if they timely furnish required information to the IRS.

Foreign Account Tax Compliance Act

Sections 1471 through 1474 of the Code and the Treasury regulations and administrative guidance promulgated thereunder (commonly referred to as the “Foreign Account Tax Compliance Act” or “FATCA”) generally impose withholding of 30% on “withholdable payments” in respect of stock of U.S. corporations that is held by or through certain foreign financial institutions (including investment funds) unless various U.S. information reporting and due diligence requirements have been satisfied or an exemption applies. An intergovernmental agreement between the United States and an applicable foreign country may modify these requirements.

For purposes of FATCA, withholdable payments generally include U.S.-source payments otherwise subject to nonresident withholding tax (e.g., U.S.-source dividends) and gross proceeds from the sale or other disposition of stock of a U.S. corporation. Proposed regulations would eliminate withholding on gross proceeds from the sale or dispositions of stock. Taxpayers may rely on the proposed regulations until final regulations are issued or such proposed regulations are rescinded. Accordingly, the entity through which shares of AIR common stock are held will affect the determination of whether such withholding is required. Similarly, “withholdable payments” (e.g., dividends) in respect of AIR common stock held by an investor that is a non-financial non-U.S. entity that does not qualify under certain exceptions generally will be subject to withholding at a rate of 30%, unless such entity either (i) certifies that it does not have any “substantial United States owners” or (ii) provides certain information regarding the entity’s “substantial United States owners” that will be provided to the Treasury. If FATCA withholding is imposed, a beneficial owner of AIR common stock that is not a foreign financial institution generally may obtain a refund of any amounts withheld by filing a U.S. federal income tax return. U.S. Holders and non-U.S. Holders should consult their tax advisors regarding the possible implications of FATCA to their investment in AIR common stock.

UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL INFORMATION

Introduction

The following unaudited pro forma condensed combined financial information has been prepared to illustrate the estimated effects of the merger based on the historical financial position and results of operations of Tenax and AIR. The information presented has been prepared in accordance with Article 11 of Regulation S-X as amended by the final rule, Release 33-10786Amendments to Financial Disclosures about Acquired and Disposed Businesses”.

These unaudited pro forma condensed combined financial statements are for informational purposes only. They do not purport to indicate the results that would have been obtained had the merger actually been completed on the assumed date or for the periods presented, or that may be realized in the future. The pro forma adjustments are based on the information currently available, and the assumptions and estimates underlying the pro forma adjustments are described in the accompanying notes. Actual results may differ materially from the assumptions made within the accompanying unaudited pro forma condensed combined financial information.

Description of the Merger

Pursuant to the merger agreement, Merger Sub will merge with and into Tenax, with Tenax continuing as the surviving entity and becoming a wholly owned subsidiary of AIR. The merger consideration will consist of 126,900,000 shares (which number will be adjusted to 25,380,000 shares after giving effect to the proposed amendment to the articles of incorporation of AIR contemplated by the authorized shares proposal and the subsequent reverse stock split, each as described in this proxy statement/prospectus) of AIR common stock to be issued to the Tenax Members and, as applicable, reserved for issuance to the Tenax Warrantholders upon the exercise of their warrants. It is expected that, at the closing of the merger and assuming no Tenax Warrantholders exercise their warrants to purchase Tenax units prior to the closing of the merger, AIR will issue 120,457,162 shares (which number will be adjusted to 24,091,432 shares after giving effect to the proposed amendment to the articles of incorporation of AIR contemplated by the authorized shares proposal and the subsequent reverse stock split, each as described in this proxy statement/prospectus) of AIR common stock to the Tenax Members.

As a result of the merger, the AIR stockholders as of immediately prior to the effective time are expected to collectively own approximately 4% of the outstanding shares of the common stock of the combined company, on a fully diluted basis, and the Tenax Members and Tenax Warrantholders as of immediately prior to the effective time are expected to collectively own approximately 96% of the outstanding shares of the common stock of the combined company, on a fully diluted basis.

Following the completion of the merger, Tenax’s operations will comprise the majority of the combined company’s operations, and Tenax Members are expected to hold a controlling interest in the combined company.

Accounting Treatment of the Merger

Although AIR is the legal acquirer in the merger, the transaction is expected to be accounted for as a reverse acquisition under Topic 805, with Tenax deemed the accounting acquirer and AIR treated as the accounting acquiree for financial reporting purposes.

Tenax has been determined to be the accounting acquirer based on an evaluation of factors including relative voting rights in the combined entity, the composition of the post-merger board of directors and other considerations under Topic 805. As a result, Tenax’s historical financial statements will become the predecessor financial statements of the combined company, and AIR’s identifiable assets and liabilities will be recognized at their estimated fair values as of the closing date in accordance with the acquisition method of accounting.

The ownership percentages above are based on the shares of AIR common stock expected to be issued and outstanding immediately following the merger. The table above does not give effect to the reverse stock split and assumes that no Tenax Warrantholders exercise their warrants to purchase Tenax units prior to the closing of the merger. The shares of AIR common stock that would underlie such unexercised warrants assumed by AIR would be reserved for future issuance by AIR. This table also excludes certain other outstanding equity awards.

NOTES TO UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL INFORMATION

Note 1 — Basis of Presentation

The unaudited pro forma condensed combined balance sheet as of March 31, 2026 gives effect to the merger as if it had occurred on March 31, 2026. The unaudited pro forma condensed combined statement of operations for the quarter ended March 31, 2026 and for the year ended December 31, 2025 gives pro forma effect to the merger as if it had occurred on January 1, 2025.

This information should be read together with the historical financial statements of each of Tenax and AIR, including the notes thereto, as well as other financial information included elsewhere in the registration statement of which this proxy statement/prospectus forms a part.

The unaudited pro forma condensed combined financial information has been prepared to illustrate the estimated effects of the merger and any related transactions. It sets forth and is derived from the following:

        Tenax’s unaudited condensed consolidated financial statements and notes of Tenax as of and for the three months ended March 31, 2026, included elsewhere in this filing;

        Tenax’s audited consolidated financial statements as of and for the year ended December 31, 2025, included elsewhere in this filing;

        AIR’s unaudited consolidated financial statements as of and for the three months ended March 31, 2026, included in the Form 10-Q filed by AIR with the SEC on May 13th, 2026, included elsewhere in this filing; and

        AIR’s audited consolidated financial statements as of and for the year ended December 31, 2025, included in the Form 10-K filed by AIR with the SEC on March 27th, 2026, which are included elsewhere in this filing.

The pro forma adjustments reflecting the consummation of the merger are based on certain currently available information and certain assumptions and methodologies that management believes are reasonable under the circumstances. The unaudited pro forma condensed combined adjustments, which are described in the accompanying notes, may be revised as additional information becomes available and is evaluated. Management believes that these assumptions and methodologies provide a reasonable basis for presenting the significant effects of the merger based on information available at the time, and that the pro forma adjustments give appropriate effect to those assumptions and are properly applied in the unaudited pro forma condensed combined financial information. As Tenax is the accounting acquirer in the merger, the unaudited pro forma condensed combined financial information is presented using Tenax as the predecessor, with AIR reflected as the accounting acquiree.

Based on Tenax’s preliminary review of Tenax’s and AIR’s summary of significant accounting policies and preliminary discussions between management teams, the nature and amount of any adjustments to AIR’s historical financial statements to conform its accounting policies and classifications to those of Tenax are not expected to be material, except the presentation reclassifications further discussed in Note 3 below. Upon the closing, management will perform a comprehensive review of the two entities’ accounting policies. As a result of the review, management may identify differences between the accounting policies of the two entities which, when confirmed, could have a material impact on the combined financial statements of the combined company.

The unaudited pro forma condensed combined financial information does not give effect to any anticipated synergies, operating efficiencies, tax savings or cost savings that may be associated with the merger. The unaudited pro forma condensed combined financial information is not necessarily indicative of what the actual results of operations and financial position would have been had the merger taken place on the dates indicated, nor are they indicative of the future results of operations or financial position of the combined company.

The historical consolidated financial statements of Tenax and AIR were prepared in accordance with GAAP and shown in U.S. dollars.

Note 2 — Calculation of Estimated Purchase Consideration and Preliminary Purchase Price Allocation

The merger will be treated as a business combination for accounting purposes, with Tenax as the deemed accounting acquirer and AIR as the deemed acquiree. Therefore, the historical basis of Tenax’s assets and liabilities will not be affected by the merger.

The unaudited pro forma condensed combined financial information was prepared using the acquisition method of accounting in accordance with Topic 805, which requires, among other things, that assets acquired and liabilities assumed in a business combination be recognized at their fair values as of the acquisition date. Any excess of the consideration transferred over the estimated fair value of the identifiable net assets acquired will be recognized as goodwill, while any excess of the estimated fair value of the identifiable net assets acquired over the consideration transferred, after reassessing the underlying measurements, will be recognized as a bargain purchase gain.

The acquisition method of accounting uses the fair value concepts defined in ASC Topic 820, “Fair Value Measurement” (“Topic 820”). Fair value is defined in Topic 820 as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Market participants are assumed to be buyers or sellers in the most advantageous market for the asset or liability. Fair value measurement for an asset assumes the highest and best use by these market participants.

Fair value measurements can be highly subjective, and it is possible the application of reasonable judgment could develop different assumptions resulting in a range of alternative estimates using the same facts and circumstances. Fair value estimates were determined based on preliminary discussions between Tenax and AIR management, due diligence efforts and information available in public filings. The preliminary allocation of the aggregate merger consideration used in the unaudited pro forma condensed combined financial information is based on preliminary estimates. The estimates and assumptions are subject to change as of the effective time of the merger. The final determination of the allocation of the aggregate merger consideration will be based on the actual tangible and intangible assets and the liabilities of AIR at the effective time. Refer to Note 4 for additional information.

Estimated Purchase Consideration

In accordance with Topic 805, the accounting acquiree AIR’s stock price is used to measure the consideration transferred in this reverse acquisition, as AIR’s stock price is more reliably measurable than the value of the equity interest of the accounting acquirer Tenax, which is a privately held entity. For the purposes of these pro forma financial statements, the estimated purchase consideration is composed of the following:

AIR shares issued and outstanding as of March 31, 2026

 

 

4,781,054

Common shares issued subsequent to March 31, 2026 for director fees and net settlement of vested RSUs

$

18,045,293

____________

(1)      The AIR stock price on July 20, 2026, at market close is used as a proxy for the market price of AIR shares on the Closing Date.

The estimated purchase consideration applied in the unaudited pro forma condensed combined financial information is preliminary and subject to modification based on the final purchase price, which includes any changes to the value of AIR’s stock and the number of AIR’s vested stock-based compensation awards when the

merger is consummated. This will likely result in a difference from the estimated purchase consideration calculated above, and that difference may be material. For example, with other assumptions held constant, an increase or decrease of 20% in the price per share of AIR common stock will produce the following estimated purchase consideration and the corresponding goodwill or gain on bargain purchase:

Note 3 — Reclassifications

During the preparation of the unaudited pro forma condensed combined financial information, management performed a preliminary analysis of Tenax’s and AIR’s financial information to identify differences in financial statement presentation and classification. Certain reclassifications have been made to the historical financial statement presentation of each of Tenax and AIR to conform to the presentation used in the unaudited pro forma condensed combined financial information.

Note 4 — Transaction Accounting Adjustments

The unaudited pro forma condensed combined financial information has been prepared to illustrate the effect of the merger and related transactions and has been prepared for informational purposes only.

The following unaudited pro forma condensed combined financial information has been prepared in accordance with Article 11 of Regulation S-X as amended by the final rule, Release No. 33-10786Amendments to Financial Disclosures about Acquired and Disposed Businesses”. Release No. 33-10786 replaces the existing pro forma adjustment criteria with simplified requirements to depict the accounting for the transaction (“Transaction Accounting Adjustments”) and present the reasonably estimable synergies and other transaction effects that have occurred or are reasonably expected to occur (“Management’s Adjustments”). Management has elected not to present Management’s Adjustments and will present only Transaction Accounting Adjustments in the unaudited pro forma condensed combined financial information.

Adjustments to Unaudited Pro Forma Condensed Combined Balance Sheet

(a)     Reflects the reclassification adjustments made to the historical financial statement presentation of each of Tenax and AIR to conform to the presentation used in the unaudited pro forma condensed combined financial information. Refer to Note 3 for adjustment detail.

(b)    Represents the preliminary acquisition accounting for AIR as the accounting acquiree, including the elimination of AIR’s historical equity balances, recognition of estimated consideration transferred, adjustments to AIR’s identifiable net assets to their preliminary estimated fair values and recognition of preliminary goodwill. Estimated consideration transferred includes $3.8 million representing the preliminary fair value of the redemption rights expected to be issued to eligible legacy AIR stockholders. The rights are assumed to be freestanding and liability-classified, with a corresponding redemption-right liability recognized in the pro forma condensed combined balance sheet.

(c)     Represents the accrual of additional transaction costs of $5.2 million directly attributable to the Mergers that are expected to be incurred by Tenax subsequent to March 31, 2026.

(d)    Reflects the repayment of AIR’s outstanding debt by Tenax at closing pursuant to the merger agreement. The adjustment eliminates AIR’s historical debt balances, including related accrued interest and unamortized deferred financing costs, as applicable, with the offset reflected through cash, financing sources, and accumulated deficit for any debt extinguishment impact. The adjustment also reflects the release and reclassification to cash and cash equivalents of restricted cash previously held as collateral for the AIR senior debt upon settlement of such debt. The adjustment further reflects the issuance of a new $30.0 million term loan, presented net of $0.4 million of estimated debt issuance costs, expected to be entered into in connection with the transaction, the proceeds of which will be used to settle AIR indebtedness. Actual debt balances, issuance costs and financing terms may differ from the amounts presented based on the final terms of the financing.

(e)     Reflects the recognition of deferred tax liabilities associated with Tenax becoming subject to corporate income tax following the merger. Historically, Tenax has been treated as a pass-through entity for U.S. federal income tax purposes, and no federal or state income tax provision has been recorded in its historical financial statements. The adjustment is reflected as an increase to deferred tax liabilities with a corresponding increase to accumulated deficit.

(f)     Reflects the equity presentation effects of the reverse acquisition, including the elimination of AIR’s historical equity balances and the presentation of Tenax’s historical members’ equity within AIR’s post-combination legal equity structure. The adjustment records the post-combination AIR common share structure, including shares issued to Tenax securityholders and legacy AIR shares retained, with the offset to additional paid-in capital and accumulated deficit, as applicable.

(g)    Reflects the assumed net settlement of Tenax notes receivable issued in connection with purchases of membership interests. The notes receivable were historically presented as a reduction of Tenax equity and are assumed to be settled against the AIR shares otherwise issuable to the applicable holders in connection with the merger.

102

Table of Contents

Adjustments to the Unaudited Pro Forma Condensed Combined Statements of Operations

(A)    Reflects the estimated income statement effects of the preliminary purchase accounting for AIR, including reduced cost of goods sold resulting from the lower fair value of inventory acquired and subsequently sold during the period, and reduced depreciation driven by the lower fair value assigned to acquired depreciable assets.

(B)    Represents $5.2 million of additional transaction costs expected to be incurred by Tenax after March 31, 2026 in connection with the merger. For purposes of the unaudited pro forma condensed combined statement of operations, these costs are reflected as if the merger had occurred on January 1, 2025. These costs are nonrecurring and are not expected to have a continuing impact on the combined company’s results of operations.

(C)    Reflects the elimination of historical interest expense, including amortization of deferred financing costs, associated with AIR’s senior and subordinated debt expected to be repaid at closing pursuant to the merger agreement. The adjustment also reflects the recognition of interest expense and amortization of debt issuance costs associated with a new $30.0 million term loan expected to be entered into in connection with the transaction, assuming the financing was outstanding as of January 1, 2025. The pro forma interest expense on the new term loan expected to be entered into at close was calculated using a 7.02% interest rate, which represents Tenax’s effective borrowing rate on its existing senior credit facility as derived from Tenax’s financial statements for the quarter ended March 31, 2026. Management believes this rate represents a reasonable estimate of the combined company’s incremental borrowing cost given the absence of executed financing terms as of the date of the unaudited pro forma condensed combined financial information. Actual interest expense may differ from the amounts presented based on the final terms, timing and amount of borrowings incurred at or following closing.

(D)    Historically, Tenax was treated as a pass-through entity for income tax purposes and did not record federal or state income tax expense. The adjustment represents the estimated current and deferred tax effects of the combined company’s pro forma results and transaction accounting adjustments. These amounts are preliminary and may differ from the actual tax provision recognized following the merger.

Note 5 — Net Earnings/(Loss) per Share

Net earnings/(loss) per share was calculated using the historical weighted average shares outstanding and the issuance of additional shares as merger consideration, assuming the shares were outstanding since January 1, 2025. As the merger is being reflected as if it had occurred at the beginning of the period presented, the calculation of weighted average shares outstanding for basic and diluted net earnings/(loss) per share assumes that the shares issuable relating to the merger have been outstanding for the entirety of all periods presented.

DESCRIPTION OF AIR BUSINESS

Introduction

We believe we are one of the leading manufacturers of precision components and assemblies for large aerospace and defense prime contractors. Our products include landing gears, flight controls, engine mounts and components for aircraft jet engines, ground turbines and other complex machines. The ultimate end-user for most of our products is the U.S. government, international governments and commercial global airlines. Whether it is a small individual component for assembly by others or complete assemblies we manufacture ourselves, our high quality and extremely reliable products are used in mission critical operations that are essential for safety of military personnel and civilians.

We specialize in the aerospace and defense markets, operating within a hierarchical network of suppliers. At the top of the supply chain pyramid is the prime contractor, also known as an original equipment manufacturer (“OEM”). A prime contractor designs, develops and produces the final product for the end-user. We play a critical role in this ecosystem, operating as a “Tier One” supplier, delivering our products directly to prime contractors, or as a “Tier Two” supplier, providing larger complex components to others. In some cases, we ship products directly to the U.S. government. Our strategic position has made us a key partner for many prominent defense prime contractors and global commercial aviation manufacturers, often leading us to become the exclusive or primary supplier for certain high precision parts and assemblies. We often receive long-term agreements (“LTAs”) from our customers, demonstrating their commitment to us.

We are renowned for our unwavering commitment to genuine quality and exceptional reliability. Our rich history dates to 1941, producing parts for World War II fighter aircraft. Since then, we have maintained an impeccable record with no known incidents of part failure leading to a mission failure or resulting in a fatality. In an era plagued by foreign counterfeit parts, we strategically operate all our facilities within the United States. Our two state-of-the-art manufacturing centers located in Long Island, New York, and Barkhamsted, Connecticut, allow for rigorous oversight of production and adherence to stringent quality standards. Spanning over 150,000 square feet, our manufacturing centers serve as the operational hubs for our three legal subsidiaries, Air Industries Machining Corp., Nassau Tool Works, Inc. and Sterling Engineering Corporation.

For the past several years, we have strategically invested substantial amounts in new capital equipment, tooling and processes to bolster our competitive position. Additionally, we have expanded our sales and marketing efforts, with a sharp focus on expanding relationships with customers and cultivating new ones.

We finished 2025 with $47.9 million of net sales. Our backlog, which represents the value of all funded orders received, stood at $136.8 million, an increase of 16.0% as compared to our backlog on December 31, 2024. On the bottom-line, we reported a net loss of $1.3 million.

Our business strategy is geared towards competing and winning contracts that enable us to achieve sustainable and profitable business growth and delivering high-quality, reliable products to our customers. At our core lies a highly trained and close-knit team of 158 individuals committed to driving excellence and precision in every aspect of our operations. We are firmly focused on securing new contract awards, improving operations and successful execution. As of March 31, 2026, and December 31, 2025, we had total unfilled contract values amounting to, respectively, $269.2 million (including our $134.7 million in backlog and all potential orders against LTAs previously awarded to us) and $270.1 million (including our $136.8 million in backlog and all potential orders against LTAs previously awarded to us).

Customer Profiles

In 2025 and 2024, respectively, approximately 58.3% and 69.9% of our net sales were attributed to customers who use our products for end-use on military aircraft. The rest of our net sales are attributable to commercial aviation uses and, to a much lesser extent, ground power electricity generation and other uses.

Table of Contents

We have cultivated long-standing relationships with many large and well-known customers, including:

        RTX Corporation (“RTX”) — RTX is a multinational aerospace and defense conglomerate and a major player in the aerospace and defense industry. We sell to several business units and/or subsidiaries of RTX, including Collins Aerospace (which includes Collins Landing Systems and Collins Aerostructures) and Pratt Whitney. RTX was formerly known as Raytheon Technologies Corporation and, prior to that, United Technologies Corporation.

        Lockheed Martin Corporation (“Lockheed Martin”) — Lockheed Martin is a leading global security and aerospace company with its principal customers being agencies of the U.S. government. We sell directly to one of Lockheed Martin’s subsidiaries, Sikorsky Aircraft Corporation (“Sikorsky”).

        Northrop Grumman Corporation (“Northrop”) — Northrop Grumman is a leading global aerospace and defense technology company. We supply product used on the E2-D Hawkeye airborne warning and control aircraft.

        General Electric Aerospace (“GE Aerospace”) — GE Aerospace is a global aerospace propulsion, services and systems leader. We supply GE Aerospace with high precision components that are used in jet turbine aircraft engines that are used on several commercial aircraft platforms.

        General Electric Vernova (“GE Vernova”) — GE Vernova is a purpose-built global energy company that includes power, electrification and wind segments. We supply GE Vernova with precision components that are used in ground-based turbines for electrical power generation.

        U.S. government — We supply certain components and assemblies directly to the Defense Logistics Agency (“DLA”), a combat support agency within the U.S. Department of War (“DoW”). DLA’s mission is to manage the end-to-end global defense supply chain and deliver readiness to the warfighter. It supports all five U.S. military services, federal, state and local agencies, as well as partner and allied nations. DLA procures items from us and provides them, as it deems fit, to other suppliers who assemble them into finished products.

Platform and Program Profiles

Most of our machined components and assemblies are integral to high-profile platforms and named programs. Platforms generally refer to equipment that is utilized in missions or operations, whereas programs are broader initiatives and can encompass the development and production of new platforms, upgrades to existing systems and other initiatives. The following platforms and programs (ranked in descending order by their 2025 net sales), accounted for 79.7% and 79.3% of our net sales in 2025 and 2024, respectively:

        Pratt & Whitney Geared Turbo-Fan Engine (“GTF”) — Used in commercial aviation, the GTF represents a new generation of jet engines that offer improved fuel efficiency, reduced emissions, and lower noise levels compared to traditional turbofan engines. We manufacture thrust struts, a critical component that essentially absorbs and distributes the forward thrust produced by the jet engine, ensuring that the force is evenly applied across the structure of the aircraft to maintain stability and integrity during takeoff, cruising and landing. We supply our thrust struts to Collins Aerostructures for integration into GTFs utilized by smaller airlines such as those operating the Airbus A220 and Embraer E2 aircraft. Demand for these engines increased in 2025, thus reducing the concentration in the net sales attributable to military end users. Demand for these engines is anticipated to increase over the next few years.

        UH-60 Black Hawk Helicopter — We supply flight critical components, such as the primary flight control assembly and the tail-rotor gearbox, for the UH-60 Black Hawk Helicopter. Serving as the primary helicopter for the U.S. Army, it fulfills essential roles in transport, troop movement, medical evacuation and cargo lift operations. Manufactured by Sikorsky, it includes many variants and is also utilized by other branches of the U.S military and U.S. allied countries. Since entering service in 1979, over 4,000 helicopters have been produced. Deployment of new helicopters is projected to continue through at least 2027, with ongoing sustainment activities anticipated for many years thereafter.

106

        CH-53 Helicopter (including the CH53K variant) — Developed in the 1960s and manufactured by Sikorsky, the CH-53 is recognized as the largest and most powerful helicopter in the U.S. military. It has evolved through several variants, with hundreds delivered and used by the U.S. Marine Corps. In 2021, we secured a LTA to supply chaff pods for the CH-53K, the latest iteration in the CH-53 series. These pods deploy metallized strips to generate false radar targets, safeguarding the helicopters from missile threats. The CH-53K plays a crucial role in the U.S. Marine Corps’ plans to support a wide range of current and future operations. In 2024, we received a purchase order to manufacture swashplates and hubs to be used on the CH-53K.

        E-2D Hawkeye — We provide the main and nose landing gear, as well as the arresting gear for the E-2D Hawkeye, a twin-engine, tactical aircraft utilized for providing advanced airborne warning and control for carrier-based operations. Often referred to as the “digital quarterback”, it conducts battlefield management and command and control operations for aircraft carrier strike groups. While primarily used by the U.S. Navy, a small number have been sold to U.S. allies, notably Japan.

        F-35 Lightning II (also known as the Joint Strike Fighter) — Manufactured by Lockheed Martin, the Joint Strike Fighter is a stealth fighter aircraft designed to replace the U.S. Air Force F-15 and the U.S. Navy and Marine Corps F-18 fighters. It includes three variants: the conventional take-off and landing F-35A, the short take-off and vertical landing F-35B and the carrier based variant F-35C. We have produced landing gear components for all three variants and currently manufacture landing gear components for the US Navy version. The production of this aircraft is expected to continue for many years, with the DoW aiming for an inventory objective of 2,456 aircraft, in addition to expected demand from other countries.

        F-18 Hornet — The F-18 Hornet, the U.S. Navy’s primary fighter aircraft, principally operates from aircraft carriers and enjoys international use, notably in Finland and Australia. Originating in the late 1960s, it has seen numerous upgrades and enhancements over the years. We manufacture complete landing gear components for several variants, supplying these to the U.S. government or Tier 1 or other suppliers for spares that go on the aircraft that were originally produced by Boeing.

        F-15 Eagle Tactical Fighter — designed for the U.S. Air Force, it is known as a dedicated air superiority fighter. Currently manufactured by Boeing, it was designed in the late 1960s with over 600 aircraft estimated to be in service. The F-15 has been exported to various countries including Israel, Saudi Arabia and Japan. Although it is anticipated that this plane will be ultimately replaced by the Joint Strike Fighter, we believe it will be flying for years to come. It boasts an impeccable combat record. We ship most of our components directly to the DoW.

Our Market

The aerospace and defense industry is dominated by a select few large prime contractors including Airbus, Boeing, General Electric, Lockheed Martin, Northrop and RTX. These prime contractors oversee large platforms and programs for the ultimate end-user, the U.S. government, foreign governments or global aviation companies.

Once a supplier is chosen and integrated into a platform or selected for a specific program, replacing them becomes a complex challenge. In many cases, suppliers often become the sole or single source. Being a sole source means being chosen as the exclusive supplier by the customer, whereas being a single source indicates that, despite the availability of other potential manufacturers, only one supplier is currently used. Single or sole sourcing is especially prevalent in the production of legacy aircraft. While prime contractors generally prefer multiple sources for new aircraft production lines to mitigate single points of failure, utilizing a single vendor can lead to higher production volumes, lower average unit costs and opportunities for quality improvements.

Demand for both defense and commercial aviation components is based on new production and subsequent maintenance, repair and overhaul (“MRO”). Flight-critical components are frequently replaced on aircraft on a flight time or flight cycle basis. The demand for MRO and after-market products can continue for many years, even decades, after the production line for new aircraft is shut down.

At a high level, we are able to monitor the DoW budget for both new production and operations and maintenance components, as well as industry reports to gauge overall industry spending. While large U.S. government programs are managed through specific budget lines and oversight structures, most, if not all, of

107

Table of Contents

our machine parts and assemblies are not explicitly identified in the U.S. government budget. Therefore, predicting period-to-period demand with precision is challenging. While we primarily rely on our customers to help us project short-term and long-term demand, the timing of receipt of contract awards and related orders is difficult to predict. Consequently, comparative period-to-period net sales for any customer or program may not be meaningful.

Sales and Marketing

Sales and marketing activities during 2025 were robust, resulting in a book-to-bill ratio of 1.36x, growth in our funded backlog to $136.8 million and total unfilled contract values amounting to $270.1 million (including our $136.8 million funded backlog and all potential orders against LTAs).

We primarily rely upon a small team of highly skilled sales and business development professionals with extensive industry experience and hands-on support from management. Our goal is to cultivate customer relationships akin to partnerships and the concept of customer alignment. For example, our customers heavily rely on suppliers to deliver high-quality parts that meet specifications in a timely and cost-effective manner. They regularly assess suppliers based on various quantitative criteria such as on-time delivery performance, defect rates, adherence to specifications, cost performance, lead times, order processing times, stockout rates and similar metrics. Therefore, one of our primary objectives is to maintain high ratings and leverage these metrics in our sales and marketing activities.

Our sales cycle varies significantly, ranging from a few weeks to over a year, depending on the complexity of the product and manufacturing steps involved. While customers may occasionally engage in spot buys, most of our orders (also known as bookings) stem from LTAs. LTAs outline the quantity and price of products the customer may order within a specified time frame. When actual products are needed, the customer places a funded order against the LTA. The value of this funded order is included in our funded backlog until we ship it. Although cancellations of funded orders are possible, customers are usually subject to termination liability, necessitating payment to us for costs incurred up to the termination date. In certain termination cases, the customer is also required to pay us a reasonable profit.

We secure new or follow-on LTAs through competitive bidding in response to a customer’s Request for Quotation (“RFQ”). These proposals detail prices based on quantities, which may vary annually, for shipments over multiple years. The bidding process typically entails several rounds of submissions and negotiations before an award is granted. For defense products, in certain cases, LTAs may be awarded or extended without a RFQ or competitive bidding. In such cases, pricing may be determined through cost analysis or audit with ultimate approval by the customer or the U.S. government.

Bookings and Backlog

Bookings represent funded orders secured during a given financial period. In fiscal 2025, bookings were $65 million, a 8.5% decrease compared to $71 million in 2024. Our “book-to-bill” ratio, which is our bookings divided by net sales, was 1.36x for 2025, an improvement over the 1.29x ratio of 2024. Although bookings are subject to wide variations in timing, resulting in period-to-period comparisons not necessarily being meaningful, we do use bookings and our book-to-bill ratio as a gauge of future net sales.

Our backlog, which can be considered our “funded backlog”, stood at $136.8 million as of December 31, 2025, marking a 16.0% increase from $117.9 million on December 31, 2024. This represents the net sales we expect to realize from funded orders received and is equivalent to our remaining performance obligations pursuant to ASC Topic 606, “Revenue from Contracts with Customers” (“Topic 606”). These funded orders, approved by customers, come from LTAs, spot buys or other contracts and are for essential machined components and assemblies used in the key platforms and programs we serve. Our definition provides visibility into the value of all firm orders. The bulk of our $136.8 million backlog is expected to ship over the next 24 months, but does not include possible or probable future orders pursuant to existing LTAs or probable contract renewals that would also contribute sales during such period. The total potential net sales under contracts actually awarded to us as of December 31, 2025, was $270.1 million, including the value of our existing funded backlog of $136.8 million.

Competition

Winning a new contract award is highly competitive. Not only must we have the capabilities to manufacture to customer design specifications, but we compete against companies that have greater financial, physical and technical resources. Our ability to win new contracts generally requires us to become a trusted partner to the customer by having the capabilities to deliver superior quality product, more quickly and with lower pricing than our competitors. Accordingly, we must continually invest in process improvements and capital equipment.

In recent years, we have strategically made significant investments to enhance our competitiveness and market position. For example, in fiscal 2025 and 2024, we invested $3,322,000 and $2,301,000 in new property and equipment to support our goals. These investments have enabled us to increase production efficiency and speed while maintaining closer tolerances, have expanded the size of products we can manufacture and have been appreciated by our customers. Any investment in 2026 will be at a much lower level.

Our competitors include Monitor Aerospace, a division of GKN Aerospace; Hydromil, a division of Triumph Aerospace Group; Heroux Devetek; and Ellanef Manufacturing, a division of Magellan Corporation.

Manufacturing, Raw Materials and Replacement Parts

Our production cycle, which spans from ordering raw materials to delivering finished products, can vary from several weeks to over a year. Consequently, for certain products, especially those involving finished assemblies, we must procure significant amounts of raw materials and begin processing well ahead of actual ship dates. This underscores the importance of efficient subcontract management in meeting customer delivery deadlines. In some cases, customers may provide us with raw materials, as they may be able to obtain better processing or delivery schedules from other suppliers, and in other cases, the customer chooses to rely on us to manage suppliers.

The price and availability of many raw materials in the aerospace industry are susceptible to fluctuations in global markets and political conditions. Most raw material suppliers are hesitant to commit to long-term contracts at fixed prices, posing a substantial risk given our strategy often entails entering into LTAs, which require us to commit to long-term price commitments. However, many of our LTAs provide pricing protection when there is a large increase in the cost of raw materials.

Employees

As of July 10, 2026, we employed 158 people. Of these, 89 were involved in manufacturing and production activities, 19 were in quality control, 45 were in administration and the remaining 5 were in sales and procurement. All of our employees are covered under a co-employment agreement with Insperity Services, LLC, a professional employer organization. This arrangement allows us to provide employees with comprehensive benefits at a lower cost than we could provide.

Air Industries Machining Corp. (“AIM”) has a collective bargaining agreement with the United Service Workers, IUJAT, Local 355 (the “Union”). This agreement is effective until December 31, 2027 and covers the majority of AIM’s 125 personnel. The agreement requires us to make specified contributions to the Union’s United Welfare Fund and United Service Worker’s Security Fund, which provide pension benefits to our employees. We are not obligated to provide any additional pension benefits to our employees. Additionally, the collective bargaining agreement contains a “no-strike” clause and a “no-lock-out” clause. We believe we maintain good relationships with the Union.

Regulations

We believe that we are in compliance with all federal, state and local laws and regulations governing our operations and have obtained all material licenses and permits required for the operation of our business. The key regulations impacting our business are further discussed below:

        Environmental Regulation and Employee Safety — We are subject to regulations administered by the United States Environmental Protection Agency, the Occupational Safety and Health Administration, various state agencies and county and local authorities acting in cooperation with federal and state authorities. Among other things, these regulatory bodies impose restrictions that require us to control air, soil and water pollution, require us to protect against occupational exposure to chemicals, including

109

Table of Contents

health and safety risks, and require notification or reporting of the storage, use and release of certain hazardous chemicals and substances. This regulatory framework imposes compliance burdens and financial and operating risks on us. Governmental authorities have the power to enforce compliance with these regulations and to obtain injunctions or impose civil and criminal fines in the case of violations.

        The Comprehensive Environmental Response, Compensation and Liability Act of 1980 (“CERCLA”) imposes strict joint and several liabilities on the present and former owners and operators of facilities that release hazardous substances into the environment. The Resource Conservation and Recovery Act of 1976 (“RCRA”) regulates the generation, transportation, treatment, storage and disposal of hazardous waste. New York and Connecticut, the states where our production facilities are located, also have stringent laws and regulations governing the handling, storage and disposal of hazardous substances, counterparts of CERCLA and RCRA. In addition, the Occupational Safety and Health Act, which requires employers to provide a place of employment that is free from recognized and preventable hazards that are likely to cause serious physical harm to employees, obligates employers to provide notice to employees regarding the presence of hazardous chemicals and to train employees in the use of such substances.

        Federal Aviation Administration — We are subject to regulation by the Federal Aviation Administration (“FAA”) under the provisions of the Federal Aviation Act of 1958, as amended. The FAA prescribes standards and licensing requirements for aircraft and aircraft components. We are subject to inspections by the FAA and may be subjected to fines and other penalties (including orders to cease production) for noncompliance with FAA regulations. Our failure to comply with applicable regulations could result in the termination of or our disqualification from some of our contracts, which could have a material adverse effect on our operations. We have never been subject to such fines or disqualifications.

        Federal Acquisition Regulations — All our U.S. government contracts and those of many of our customers are subject to the procurement rules and regulations of FAR. As such, many of our LTAs require us to adhere to these rules and regulations. During and after the fulfillment of a government contract, we may be audited in respect of the direct and allocated indirect costs attributed to the project. These audits may result in adjustments to our contract costs. Additionally, we may be subject to U.S. government inquiries and investigations because of our participation in government procurement. Any inquiry or investigation can result in fines or limitations on our ability to continue to bid for government contracts and fulfill existing contracts.

Properties

We have strategically located our properties in the U.S. We lease and maintain an approximately 81,000 square foot state-of-the-art manufacturing facility located in Bay Shore, New York. We maintain our corporate headquarters at this facility whose lease expires in September 2026.

We own a second 74,923 square foot state-of the-art manufacturing facility located in Barkhamsted, Connecticut.

Legal Proceedings

On October 2, 2018, Contract Pharmacal Corp. (“Contract Pharmacal”) commenced an action relating to a sublease entered into between the Company and Contract Pharmacal in May 2018 with respect to the property that was formerly occupied by the Company’s former subsidiary WMI at 110 Plant Avenue, Hauppauge, New York. In the action, Contract Pharmacal sought damages for an amount in excess of $1,000,000 for the Company’s alleged violation of the terms of the subject sublease, specifically the failure to make the entire premises available by what Contract Pharmacal claims was the sublease commencement date. The validity of the action is extremely suspect in that the subject sublease had no specific commencement date and Contract Pharmacal ultimately received all the space. Discovery was conducted, and Contract Pharmacal moved for summary judgement and to amend its complaint to add a new cause of action, all of which the Company opposed. On July 8, 2021, the court denied Contract Pharmacal’s motion for summary judgement and to add a cause of action. In its order, the court granted Contract Pharmacal’s motions to drop its claim for specific performance and to amend its complaint to reduce its claim for damages to $700,000, both of which benefit the Company. Following the court’s decision, Contract Pharmacal filed a motion to reargue its original motion, which the Company opposed. The court denied that motion

110

Table of Contents

on November 30, 2021, and then on March 10, 2022, Contract Pharmacal filed an appeal of the court’s decision with the Appellate Division of the State of New York. The Company opposed that action. The Company was again successful, as the Appellate Division upheld the lower court’s denial of Contract Pharmacal’s motion for summary judgment and its motion to amend its complaint. Contract Pharmacal has now submitted a motion to the Appellate Division requesting leave to reargue the court’s denial of its original appeal. The Company will oppose that motion. The Appellate Division has yet to act with respect to Contract Pharmacal’s most recent motion to reargue the Court’s denial of the original appeal. The Company continues to dispute the validity of the claims asserted by Contract Pharmacal and intends to contest them vigorously.

From time to time we may be engaged in various lawsuits and legal proceedings in the ordinary course of our business. We are currently not aware of any legal proceedings the ultimate outcome of which, in our judgment based on information currently available, would have a material adverse effect on our business, financial condition or operating results. There are no proceedings in which any of our directors, officers or affiliates, or any registered or beneficial stockholder of our common stock, is an adverse party or has a material interest adverse to our interest.

Business Overview

We believe we are one of the leading manufacturers of precision components and assemblies for large aerospace and defense contractors. Our rich history dates to 1941, producing parts for World War II fighter aircraft. Since then, we have maintained an impeccable record with no known incidents of part failure leading to a fatal mission. We became a public company in 2005.

Our products include landing gear, flight controls, engine mounts and components for aircraft jet engines and ground turbines and other complex machines. The ultimate end-user for most of our products is the U.S. government, international governments and commercial global airlines. Whether it is a small individual component for assembly by others or complete assemblies we manufacture ourselves, our high quality and extremely reliable products are used in mission critical operations that are essential for safety of military personnel and civilians.

Although our net sales are concentrated amongst a number of defense and aerospace prime contractors, we have cultivated long-standing relationships with a number of their subsidiaries and/or business units. Additionally, our net sales are generated across several high-profile platforms and programs, including the F-18 Hornet, the E-2 Hawkeye, the UH-60 Black Hawk Helicopters, GTF Engines (used on smaller aircraft such as the Airbus A220 and Embraer E2), the CH-53 Helicopter, the F-35 Lighting II and the F-15 Eagle Tactical Fighter. In many cases, we are the sole or single supplier of certain parts and components and receive LTAs from our customers, demonstrating their commitment to us.

Winning a new contract award is highly competitive. Our ability to win new contract awards generally requires us to deliver superior quality products, more quickly and with lower pricing than our competitors. Accordingly, we must continually invest in process improvements and capital equipment. Recent investments in new equipment have improved the productive capacity of our employees, increased our efficiency and speed and expanded the size of products we can manufacture. We strategically operate two state-of-the-art manufacturing centers in the U.S. This allows for rigorous oversight of production and adherence to stringent quality standards. Although there is currently a shortage of skilled workers, we maintain a highly trained and close-knit team of over 160 professionals committed to driving excellence and precision in every aspect of our operations.

Our period-to-period net sales and operating results are significantly impacted by timing. In addition, our gross profit is affected by a variety of factors, including the mix and complexity of products, production efficiencies, price competition and general business operating environments. In some cases, our gross profit is impacted by our ability to deliver replacement parts on short notice. Our operations have a large percentage of fixed factory overhead. As a result, our profit margins are highly variable with sales volumes.

For the past several years, despite facing significant financial and operational challenges, we have strategically invested substantial amounts in new capital equipment, tooling and processes to bolster our competitive position. Additionally, we expanded our sales and marketing efforts, with a sharp focus on expanding relationships with existing customers and cultivating new ones.

Net Sales

Net sales for the three months ended March 31, 2026 were $11,606,000, a decrease of $529,000, or 4.4%, compared with $12,135,000 that we achieved in the three months ended March 31, 2025. The period-over-period decrease in net sales was primarily due to overall changes in the mix of products requested by customers, which are discussed further below.

Period-to-period changes in customer mix and related platforms and programs are largely attributable to customer requirements, availability of parts, production capacity and timing.

Gross Profit

Gross profit for the three months ended March 31, 2026 was $2,602,000, as compared to $2,034,000 for the three months ended March 31, 2025. Our gross profit percentage for the three months ended March 31, 2026 increased to 22.4% from 16.8% for the three months ended March 31, 2025. The increase in margin can be attributable to changes in sales across our major platforms, shifts in product mix and overall operating efficiencies. During the second half of 2025, we implemented several cost reductions that benefited our gross profit during the three months ended March 31, 2026 that were not in place during the three months ended March 31, 2025.

Operating Expenses

Operating expenses were $3,167,000 for the three months ended March 31, 2026, an increase of $387,000, or 13.92%, from $2,780,000 for the three months ended March 31, 2025. As a percentage of consolidated net sales, operating expenses increased to 27.3%, compared to 22.9% achieved during the three months ended March 31, 2025. The dollar increase was primarily driven by increases in stock-based compensation costs and professional fees, as well as costs associated with the continued improvement of our information technology system and hardening our cyber-security defenses. We continue to look for ways to reduce our costs and improve our operating performance and financial results.

Interest Expense

Interest expense (which includes amortization of deferred financing costs) was $494,000 during the three months ended March 31, 2026, an increase of $50,000, or 11.2%, from $444,000 during the three months ended March 31, 2025. The increase is primarily attributable to the higher loan balances under our credit facility with Webster Bank (the “Current Credit Facility”). The average interest rate on outstanding debt pursuant to our Current Credit Facility decreased to 6.10% in 2026 as compared to 6.85% in 2025.

Net Loss

Net loss for the three months ended March 31, 2026 was $1,020,000, compared to a net loss of $988,000 for the three months ended March 31, 2025, for the reasons discussed above.

Gross Profit

Gross profit for the year ended December 31, 2025 amounted to $8,187,000, a decrease from $8,932,000 in 2024. Our gross profit percentage in fiscal 2025 increased to 17.1% from 16.2% in 2024. This improvement can be attributed to changes in sales across our major platforms, shifts in product mix and cost reductions implemented during the period.

Operating Expenses

In fiscal 2025, operating expenses totaled $8,525,000, an increase of $52,000 from $8,473,000 recorded in 2024. As a percentage of consolidated net sales, operating expenses rose to 17.8%, compared to 15.4% in fiscal 2024. The dollar increase was due primarily to stock compensation expense and information technology expenses offset by lower personnel costs. We continue to look for ways to reduce our operating expenses.

Interest Expense

Interest expense (which includes amortization of deferred financing costs) was $1,841,000 in fiscal 2025, a decrease of $52,000, or 2.8%, from $1,893,000 in 2024. The decrease is primarily attributable to lower levels of subordinated debt during a portion of the year and a decrease in the average interest rate on debt outstanding pursuant to our Current Credit Facility, which decreased to 6.72% in 2025 as compared to 7.66% in 2024.

Net Loss

Net loss for the year ended December 31, 2025 was $1,305,000, compared to a net loss of $1,366,000 for the year ended December 31, 2024, for the reasons discussed above.

Liquidity and Capital Resources

As of March 31, 2026, we have debt service requirements related to:

        Outstanding indebtedness under our Current Credit Facility of $24,876,000 (consisting of a revolving loan of $19,283,000 and a term loan in the amount of $5,593,000). This debt matures on September 30, 2026, and requires us to make monthly payments on the term loan of approximately $87,000 until the loan matures.

        Related Party Notes of approximately $4,871,000, maturing on October 1, 2026.

        Various equipment leases and contractual obligations related to our normal business, including advances under our solar credit facility for the installation of solar energy systems including the replacement of the existing roof at our Sterling Facility.

Under the terms of the Current Credit Facility, as amended, we are required to meet a prescribed Fixed Charge Coverage Ratio (“FCCR”) (as defined in the Current Credit Facility) that is determined at the end of each fiscal quarter. This ratio is a financial metric that we use to measure our ability to cover fixed charges such as interest and lease expenses divided by EBITDA. As of March 31, 2026, the Company is required to meet a FCCR of 1.10x. As of March 31, 2026, we were not in compliance with this ratio, having only attained a ratio of 0.93x. We are in compliance with all other required business and financial covenants.

The Current Credit Facility and Related Party Notes are classified as current liabilities on the condensed consolidated balance sheet as of March 31, 2026. As a result of the due dates of this debt, there is substantial doubt about our ability to continue as a going concern for the twelve months following the date of filing of these consolidated financial statements. In addition, we are in default under our Current Credit Facility due to our failure to meet the FCCR required for the period ended March 31, 2026. Webster Bank has advised us that it will not renew our Current Credit Facility.

The Current Credit Facility expires on September 30, 2026. In addition, we are required to maintain a collection account with our lender into which substantially all cash receipts are remitted. As we are in default under the Current Credit Facility, our lender could choose to increase the rate of interest or refuse to make loans under the revolving portion of the Current Credit Facility and keep the funds remitted to the collection account. If the

116

Table of Contents

lender were to raise the rate of interest, it would adversely impact our operating results. If the lender were to cease making new loans under the revolving facility, we would lack the funds to continue operations. The Current Credit Facility expiration date and the rights granted to the lender, combined with the reasonable possibility that we might fail to meet covenants in the future, raise substantial doubt about our ability to continue as a going concern for the one year commencing as of the date of filing this proxy statement/prospectus. To date, the lender has chosen not to exercise any of its remedies, though we have agreed to place $3,930,000 of at-the-market offering proceeds in an interest-bearing account to serve as additional security for the Company’s obligations under the Current Credit Facility.

To support current operations and strategic initiatives, beginning in December 2024 we raised capital through public market sales of our common stock and believe we can continue to access equity markets in future periods, though there is no assurance as to our ability to do so or as to the price and terms under which we could issue equity securities. During the year ended December 31, 2025, the Company sold 1,213,593 shares of common stock in the public market and generated gross proceeds of $4,869,000, of which approximately $3,930,000 is restricted for the benefit of the Current Credit Facility lender. Since initiating the sales in December 2024, we have sold a total of 1,330,444 shares for gross proceeds of $5,375,000. In light of ongoing negotiations with our lenders and in accordance with the merger agreement, we have temporarily paused all equity raising activity.

The following is a brief discussion of the recent amendments to the Current Credit Facility (all of which have been filed with the SEC):

        On January 30, 2025, we entered into an Eighth Amendment to provide for an additional term loan in the amount of $1,640,000 for the acquisition of equipment. The monthly principal installments on this additional term loan are $19,524. This amendment further revised our financial covenants. For the rolling twelve-month periods ending March 31, 2025 and June 30, 2025, we were required to achieve a FCCR of 1.05x. Beginning with the rolling twelve-month period ending September 30, 2025 and going forward, the Company was required to achieve a FCCR of 1.25x. All other covenants remained unchanged. In connection with these changes, the Company paid an amendment fee of $20,000.

        On September 10, 2025, the Company entered into a Ninth Amendment where we agreed that $3,930,000 of the proceeds from our at-the-market offering would be maintained in an interest-bearing account. The funds in this account serve as security for our obligations under the Current Credit Facility.

        On December 15, 2025, the Company entered into a Tenth Amendment, which waived the defaults caused by the failure to achieve the required FCCR for the fiscal quarter ended June 30, 2025, and for exceeding the permitted amount of capital expenditures for the fiscal year ending December 31, 2025. Additionally, the maturity date of the revolving credit and term loans were extended to March 31, 2026, and the capital expenditure covenant was amended. The company paid an amendment fee of $40,000.

        On February 26, 2026, the Company entered into an Eleventh Amendment, which extended the maturity date of the revolving credit and term loans to September 30, 2026. The company paid an amendment fee of $25,000 and agreed to pay an additional fee of $150,000 on the maturity date of the Current Credit Facility.

If we are unable to close the merger or obtain a new lender to replace the Current Credit Facility, we may not be able meet our financial obligations. As of March 31, 2026, we have borrowing capacity of approximately $787,000 under the revolving loan.

In addition to required term loan payments, we may have to make additional payments under the Current Credit Facility. For so long as the term loan under the Current Credit Facility remains outstanding, if Excess Cash Flow (as defined in the Current Credit Facility) is a positive amount for any fiscal year, we are obligated to pay an amount equal to the lesser of (i) twenty-five percent (25%) of the Excess Cash Flow and (ii) the outstanding principal balance of the term loan. Such payment shall be applied to the outstanding principal balance of the term loan, on or prior to the April 15 immediately following such fiscal year. For the fiscal year ended December 31, 2025, based on the calculation there was no Excess Cash Flow payment required.

In addition to the outstanding indebtedness under the Current Credit Facility and Related Party Notes, we have various equipment leases and contractual obligations of an ongoing nature which we service in the ordinary course out of our cash flow from operations.

117

Table of Contents

Our material cash requirements are for debt service, funding working capital and capital expenditures. We have historically met these requirements with funds provided by a combination of cash generated from operating activities and cash generated from equity and debt financing transactions. Based on our current revenue visibility, strength of our backlog and availability under our Current Credit Facility, we believe that we have sufficient liquidity to meet our day-to-day cash requirements for our operations. However, we must pay or refinance large portions of our indebtedness prior to September 30, 2026. Further, as a condition to refinancing our Current Credit Facility prior to September 30, 2026, a new lender may require that the holders of our Related Party Notes extend or otherwise modify the subordination agreements they have given in favor of the lender.

If we do not close the merger, it is unlikely we will be able to pay existing debt and will need to refinance our Current Credit Facility and Related Party Notes. We have engaged in discussions with Webster Bank and the holders of our Related Party Notes to explore potential extensions or refinancings of our obligations. Webster Bank has advised us that it will not extend our Current Credit Facility. Refinancing our indebtedness may require us to pay higher interest rates than we currently pay, agree to more restrictive business or financial covenants or involve the issuance of debt, equity and/or new securities convertible into or exercisable or exchangeable for our common stock. Any failure to refinance our existing debt or obtain additional working capital when required would have a material adverse effect on our business and financial condition.

See Note 5 “Debt” in the notes to AIR’s consolidated financial statements beginning on page F-11 of this proxy statement/prospectus for additional information regarding our outstanding indebtedness.

For the three months ended March 31, 2026, we used $1,298,000 in operations, as compared to a cash flow provided of $1,525,000 for the three months ended March 31, 2025. The decrease was due primarily to increases in inventory and accounts receivable and a decrease in accounts payable, partially offset by an increase in customer deposits.

For the three months ended March 31, 2025, we generated $1,525,000 from operations which was mainly attributable to a decrease in accounts receivable and the collection of contract costs receivable.

Cash Provided by (Used in) Investing Activities

During our most recent quarter, we continued to make investments to enhance our competitiveness and market position. Cash used in investing activities of $425,000 and $1,217,000 during the three months ended March 31, 2026 and 2025, respectively, was for new property and equipment.

The investments made in the first quarters of 2026 and 2025 increased our production efficiency and speed, while maintaining closer tolerances. We intend to limit capital expenditures until such time as our debt situation is resolved.

For the year ended December 31, 2025, our operations absorbed $1,352,000 of cash, as compared to generating $324,000 of cash in fiscal 2024. The use of cash was due to an increase in inventory of $5,450,000, reflecting material and production costs incurred for product to be delivered in 2026. This was partially offset by non-cash expenses of depreciation and stock-based compensation in the amounts of $2,499,000 and $1,047,000, respectively, and by a reduction in accounts receivable of $1,761,000.

For the year ended December 31, 2024, we generated cash flows from operations of $324,000, as compared to $4,862,000 for fiscal 2023. The decrease in cash flows was primarily due to the use of a portion, $2,442,000, of customer deposits which had been advanced prior to 2024 for the procurement of long lead time raw materials expected to be utilized in 2024.

Cash Provided by (Used in) Investing Activities

During 2025, we continued to make significant investments to enhance our competitiveness and market position. Cash used in investing activities of $3,122,000 and $2,285,000 in 2025 and 2024, respectively, was for new property and equipment.

The investments in 2025 and 2024 increased production efficiency and speed, while maintaining closer tolerances. They also expanded the size of products we can manufacture.

Cash Provided by (Used in) Financing Activities

For the year ended December 31, 2025, cash provided by financing activities was $8,331,000. During fiscal 2025, we increased borrowings under our Current Credit Facility by $5,343,000 (consisting of a net increase in revolving loan borrowings of $4,713,000 and a net increase of $630,000 against the term loan). We also sold an aggregate of 1,213,593 shares of common stock to the public for net proceeds of $4,638,000. We used cash by paying $1,291,000 of the Related Party Notes. We also made payments of $223,000 pursuant to financing lease obligations and $8,000 on a loan payable.

For the year ended December 31, 2024, cash provided by financing activities was $2,368,000. During fiscal 2024, we increased borrowings under our Current Credit Facility by $2,238,000 (consisting of a net increase in revolving loan borrowings of $2,101,000 and a net increase of $137,000 against the term loan) and received advances of $8,000 against the solar credit facility. We also sold an aggregate of 116,851 shares of common stock to the public for net proceeds of $327,000. Additionally, we made payments of $196,000 pursuant to financing lease obligations and $9,000 on a loan payable.

Off-Balance Sheet Arrangements

We did not have any off-balance sheet arrangements as of March 31, 2026.

Critical Accounting Estimates

A critical accounting estimate is one that is both important to the portrayal of a company’s financial condition and results of operations and requires management’s most difficult, subjective or complex judgements, often as a result of the need to make estimates about the effect of matters that are inherently uncertain.

The preparation of financial statements in accordance with generally accepted accounting principles in the U.S. requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. The financial statements include estimates based on currently available information and our judgment as to the outcome of future conditions and circumstances. Significant estimates in these financial statements include inventory valuation, useful lives and impairment of long-lived assets, income tax provision and allowance for credit losses. Changes in the status of certain facts or circumstances could result in material changes to the estimates used in the preparation of the financial statements, and actual results could differ from the estimates and assumptions.

Below is a description of our critical accounting estimates:

        Inventory valuation, which includes the estimates and methodology used in accounting for the transition of production costs to inventory costs. In our consolidated financial statements, inventory is reflected at the lower of cost or net realizable value. We periodically evaluate inventory items not secured by backlog and establish write-downs to estimated net realizable value for excess quantities, slow-moving goods (defined as goods which do not have an open order and have not had movement for two years), obsolescence and for other impairments of value.

        We account for income taxes under the asset and liability method, based on the income tax laws in the United States. This approach requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of temporary differences between the carrying amounts and the tax basis of assets and liabilities using expected rates in effect for the tax year in which the differences are expected to reverse. Developing the provision for income taxes requires significant judgment and expertise in federal, international and state income tax laws, regulations and strategies, including the determination of deferred tax assets and liabilities and, if necessary, any valuation allowances that may be required for deferred tax assets. The Company has recorded a valuation allowance in the current and prior years to reduce deferred tax assets to zero. If we were to subsequently determine that we would be able to realize deferred tax assets in the future in excess of its net recorded amount, an adjustment to deferred tax assets would increase net income for the period in which such determination was made. We will continue to assess the adequacy of the valuation allowance on a quarterly basis. Our judgments and tax strategies are subject to audit by various taxing authorities.

Evaluation of Disclosure Controls and Procedures

Our management, with the participation of our Acting Chief Executive Officer (“CEO”) and Vice President of Finance, who is our principal financial and accounting officer (“PFO”), evaluated the effectiveness of our disclosure controls and procedures, as defined in Rule 13a-15(e) and 15d-15(e) under the Exchange Act, as of March 31, 2026. Our disclosure controls and procedures are designed to provide reasonable assurance that information we are required to disclose in the reports we file or submit under the Exchange Act is accumulated and communicated to our management, including our CEO and PFO, as appropriate to allow timely decisions regarding required disclosures, and is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms. Based on this evaluation, and as a result of the material weakness described below, our CEO and PFO have concluded that our disclosure controls and procedures were not effective as of March 31, 2026.

Management’s Report on Internal Control over Financial Reporting

Management is responsible for establishing and maintaining adequate internal control over financial reporting. Internal control over financial reporting refers to those policies, procedures and processes that pertain to the maintenance of records that accurately and fairly reflect transactions with respect to our assets; provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles and that receipts and expenditures are made only in accordance with authorizations of our management; and provide reasonable assurance regarding the prevention and timely detection of unauthorized transactions with respect to our assets that could have a material effect on our financial statements.

Because of inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Management assessed the effectiveness of our internal control over financial reporting as of December 31, 2025. In making this assessment, management used criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission in Internal Control — Integrated Framework (2013).

As reported in the 2025 Form 10-K, in connection with their review of our internal controls as of and for the year ended December 31, 2025, our management determined that a material weakness previously identified in our internal controls over financial reporting related to our information technology (“IT”) systems had yet to be remediated.

Historically, we outsourced certain IT-related functions to a third-party vendor. In 2022, we identified a material weakness with respect to our IT systems in that we did not design and/or implement primary user access controls and program change management systems over key IT systems to validate that data produced by the relevant IT systems were complete and accurate and to ensure appropriate segregation of duties to adequately restrict user and privileged access to the financially relevant systems and data to our personnel. Further, we identified a material weakness with respect to the activities of our vendor in connection with the design and operation of our IT systems; because this vendor is unable to provide a Standard Operating Control Report, we were unable to verify and validate the effectiveness of the vendor’s control procedures when implementing changes to our IT systems, including systems affecting our financial IT applications and underlying data account records.

During fiscal 2025, we implemented new IT controls that required our third-party vendor to make only changes to our IT systems with specific authorization and a requirement that such change be monitored in real-time by an employee of the Company that is familiar with the changes that are being made by our third-party vendor. Although we implemented a process to monitor users being granted privileged access and that such access is being monitored by a periodic user review process, additional enhancements and more formalized documentation is still required. Tests of such controls and procedures are ongoing, and the material weakness noted will only be deemed to have been remediated after the new controls and procedures have been in place for a sufficient period and management has concluded through appropriate testing that the controls are operating effectively. As such, we consider this material weakness not to be remediated as of March 31, 2026. Based on this evaluation and as a result of this material weakness, we have concluded that our disclosure controls and procedures were not effective as of March 31, 2026.

During 2026, the Company is continuing to test such controls and procedures designed to remediate the aforementioned material weakness.

Changes in and Disagreements with Accountants on Accounting and Financial Disclosure

On April 16, 2025, Marcum LLP (“Marcum”) notified us that Marcum resigned as our independent registered accounting firm. On November 1, 2024, CBIZ CPAs P.C. (“CBIZ”) acquired the attest business of Marcum. On April 17, 2025, following the approval of the Audit Committee of the AIR Board, CBIZ was engaged, effectively immediately, as our independent registered public accounting firm for the fiscal year ended December 31, 2025. During the years ended December 31, 2024 and 2023 and through the date on which Marcum advised us of their resignation, there were no disagreements (as defined in Item 304(a)(1)(v) of Regulation S-K and related

instructions) with Marcum on any matter of accounting principles or practices, financial statement disclosure or auditing scope or procedure, which disagreements, if not resolved to Marcum’s satisfaction, would have caused them to make reference thereto in their reports on the Company’s financial statements for such periods.

Other than as described above, there have not been any changes in our internal control over financial reporting, as such term is defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act, during our two most recent fiscal years that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

DESCRIPTION OF TENAX BUSINESS

Company Overview

Tenax is an aerospace and defense supplier of special mission aircraft and related products and services sold primarily to the U.S. and other governments, either directly or through prime contractors. Tenax’s offerings include aircraft procurement, modification, operations and financing; engineering and systems integration; and program management. Tenax’s programs support missions critical to national security and the public interest, including aerial firefighting; mapping and monitoring; intelligence, surveillance and reconnaissance work; testing of airborne sensors and training of airborne sensor operators.

Tenax acquires general aviation aircraft and modifies, integrates and operates them to meet a customer’s requirements. Unlike many of its competitors, Tenax does not acquire and modify aircraft without a customer contract in hand. Tenax’s business is mostly direct-to-customer contract awards most often structured under Contractor Owned, Contractor Operated (“COCO”) arrangements. Tenax’s contracts vary in the level of support Tenax provides, from a high level of support, including Tenax-supplied pilots and maintenance personnel, to no support after the modifications have been completed. On some of its contracts Tenax is a sole source supplier.

Tenax was founded in 2001 and today operates with headquarters in Ridgeland, Mississippi, with additional operations and facilities in Arlington, Virginia, and Hagerstown, Maryland. In January 2018, Tenax was acquired by Thomas Foley, Taran Bakker and other investors organized by NTC Group, an investment and management services company based in Greenwich, Connecticut. Mr. Foley currently owns approximately 57.8% of Tenax, and Mr. Bakker currently owns approximately 13.1% of Tenax. Mr. Foley has more than 40 years of experience acquiring and operating businesses in the aerospace and defense industry. He worked at McKinsey & Co. and Citicorp Venture Capital before forming NTC Group in 1985. Mr. Bakker also worked at McKinsey & Co. and then Morgan Stanley, before joining Goldman Sachs where he spent twelve years in mergers and acquisitions and five years acquiring and overseeing companies for Goldman Sachs Capital Partners Fund VI.

After acquiring Tenax, Mr. Foley and Mr. Bakker refocused Tenax’s strategy toward durable missions and “sticky” contracts. Contracts become sticky when customer switching costs are high, either because Tenax has unique expertise suitable for performing the contract, Tenax owns intellectual property related to the contract, the customer has a significant investment in modifications made to a Tenax asset or the contract is sole sourced. To grow the business more rapidly and implement this refocused strategy, Mr. Foley and Mr. Bakker hired a new president and a new business development team. Tenax’s net income grew from approximately $965,384 in 2019 to $18.6 million in 2025. Tenax’s EBITDA grew from approximately $30 million in 2019 to a current Run-Rate EBITDA3 of more than $72 million, representing a 15.7% growth rate over the period. Most of that EBITDA growth was internal, but approximately $13.5 million of 2025 EBITDA can be attributed to Tenax’s 2022 acquisition of DS Technologies, LLC (“DST”), an aerospace and defense supplier of products and services, including modified ISR aircraft, signal intelligence sensor testing, sensor training and operations and other ISR mission support.

An important part of Tenax’s strategy is growth through acquisitions. Tenax looks for acquisition opportunities that complement its current aerospace and defense business, including acquisition targets that provide different aircraft and roles for firefighting, ISR and other types of special mission work. Tenax also looks for acquisition targets that provide similar aircraft and roles outside of the U.S., as well as companies that could internalize some or all of Tenax’s aircraft modification and maintenance work. Tenax has and expects to continue to pursue opportunities where unmanned aircraft can perform special mission roles currently performed by manned aircraft. Following completion of the merger with AIR, Tenax expects to pursue acquisitions of other aerospace and defense product and component manufacturing businesses that are related to Tenax’s and AIR’s current markets or customer bases. Mr. Foley and Mr. Bakker, through NTC Group, are heavily involved in operations and decision-making at Tenax and lead the effort to identify potential acquisitions. NTC Group brought Tenax the DST acquisition opportunity as well as the current merger opportunity with AIR. NTC Group regularly brings acquisition opportunities to Tenax for its consideration. Tenax expects that acquisitions will be a significant contributor to Tenax’s future growth.

Tenax takes a long term view toward investing in its business and is conservative in its approach to acquisitions. In the past, Tenax has not typically participated in auctions and has not sought to purchase businesses

that have been purchased relatively recently by the seller, as in the case of private equity-owned businesses. Tenax is cautious about paying for synergies when purchasing a company. Rather than fully integrating the businesses it acquires, Tenax prefers a cooperating but standalone portfolio company model. However, businesses that Tenax acquires that are government contractors will generally benefit from close coordination with Tenax’s business development team. Tenax focuses its acquisitions primarily on founder- and family-owned businesses that have a strategic rationale that aligns with Tenax’s business, have a sustainable competitive advantage and can be purchased at a conservative multiple with a significant portion of the purchase price being contingent on future performance.

Mr. Foley and Mr. Bakker are not compensated directly by Tenax. Pursuant to a management services agreement and a financial services agreement between NTC Group and Tenax, Tenax pays management and financial services fees to NTC Group which, in turn, compensates Mr. Foley and Mr. Bakker. The annual management fee payable to NTC Group is approximately five percent of Tenax’s annual EBITDA. Financial services fees payable to NTC Group are up to 1% of the aggregate amount of any financing and, in the case of mergers or acquisitions, up to 1.5% of the enterprise value. Management fees paid to NTC Group were $2,621,000 and $2,894,000 in 2024 and 2025, respectively. No financial services fees were paid in 2024 or 2025. A $1 million financial services fee was paid to NTC Group in connection with the purchase of Bain Capital Credit’s equity in Tenax and the related refinancing in January 2026.

Tenax does not currently file reports with the SEC. Tenax’s Internet address is www.tenaxaerospace.com. Information contained on, or that can be accessed through, Tenax’s website is not incorporated by reference into this proxy statement/prospectus, and you should not consider information on Tenax’s website to be part of this proxy statement/prospectus.

Verticals

Aerial Firefighting

Tenax serves as the prime contractor to the U.S. Forest Service for the Aerial Supervision Module (“ASM”) program. The ASM program includes a fleet of 16 aircraft that deliver approximately 3,900 flight hours annually and maintain operational readiness of over 99 percent as of March 31, 2026. These aircraft conduct both Lead Plane and Airborne Fire Management roles. The Lead Plane role involves laying down a smoke trail showing tanker aircraft where to drop their fire retardant. The Airborne Fire Management role involves coordinating communications over the fire. Tenax equips these aircraft with special mission radios, infrared cameras and satellite communications to support coordinated air attack operations. Tenax also supports the U.S. Forest Service and CAL FIRE with additional aircraft for other roles, including precision aerial fire mapping and tactical electro-optical/infrared (“EO/IR”) support. These programs are structured with different levels of support for the customer, including contracts where Tenax supplies only the aircraft and other programs where Tenax supplies the aircraft, pilots, maintenance and sensor operations.

Mapping and Multi-Mission Aircraft

Tenax operates aircraft that combine high-altitude mapping and intelligence, surveillance and reconnaissance (“ISR”) capabilities. Under the U.S. Army Geospatial Center’s HR3D program, Tenax provides aircraft to various U.S. Combatant Commands such as AFRICOM and INDOPACOM. These aircraft carry various combinations of high-altitude light detection and ranging (“LiDAR”) sensors, foliage-penetrating sensors, high-definition photographic sensors, EO/IR sensors with full motion video and signals intelligence (“SIGINT”) sensors. These aircraft are capable of mapping up to 1,000 square miles per day. While mapping is the primary mission, these aircraft are configured to fulfill ISR roles. Under the HR3D program, Tenax provides pilots and maintenance personnel under COCO arrangements, including in locations outside the continental U.S. Tenax also provides aircraft for the FBI Critical Incident Response Group to support a wide range of missions and aircraft for the U.S. Navy’s continental U.S.-based training and transportation needs.

Intelligence, Surveillance and Reconnaissance

Tenax assists with SIGINT, Electronic Warfare and Imagery Intelligence (or EO/IR) missions for certain customers. Tenax provides aircraft for these purposes to the U.S. government and to partner nations with Tenax providing flight operations and maintenance support. Tenax also supports maritime patrol and border surveillance

124

for the Florida Department of Law Enforcement by providing aircraft equipped with EO/IR, radar, Starlink communications, a proprietary mission control system and special law enforcement radios. Tenax also provides the U.S. Army with two aircraft for its medium-altitude ISR missions supporting national security.

Sensor Integration, Modification, Testing and Training and Logistics Support

Tenax, through DST, provides aircraft configured to accept a variety of U.S. government-owned SIGINT sensors for characterization, calibration and testing. DST also provides sensor operator training on aircraft and in classrooms. DST’s training curricula include flight operations, aircraft maintenance and aircraft and sensor operations instruction. DST procures, modifies and, in some cases, operates ISR and SIGINT aircraft for customers in the intelligence and law enforcement communities. Most of DST’s contracts are sole sourced and classified.

Industry Overview

Tenax’s business falls within the aerospace and defense supplier sector. According to the Aerospace and Defense Market Report 2026, published in January 2026 by The Business Research Company, the aerospace and defense market is estimated to be approximately $900 billion and is expected to grow approximately 7.1% annually through 2030. The recent shift in U.S. military spending priorities away from consulting services and toward combat readiness is beneficial to Tenax. A recently proposed expansion of the annual U.S. military budget from approximately $900 billion to approximately $1.5 trillion and supplemental bills to finance the U.S. war in Iran, if passed, are likely to significantly increase business for aerospace and defense suppliers, including Tenax. The emergence of near-peer status with China and other causes of rising global tensions, the aging of U.S. government aircraft fleets and the need for quicker fulfillment of requirements should also increase long term demand for Tenax’s products and services. Commercial demand for special mission aviation work in areas such as environmental monitoring, search and rescue and border patrol is expected to grow as technology expands the capability of aircraft to perform these missions. Advances in avionics, sensors and communications continue to increase the range and value of airborne mission applications. Tenax’s focus on enduring missions and its ability to deliver very flexible aircraft solutions position it to benefit from all of these favorable long term trends.

Business Strategy & Competitive Strengths

Tenax’s goal is to be the most reliable special mission resource and most trusted partner for its customers. Tenax achieves this goal by pricing its products and services reasonably, delivering quality and up-to-date equipment on time and providing maximum operational availability. Tenax only pursues high value, durable business such as firefighting, mapping, intelligence gathering, military training and medical evacuations.

Tenax’s business strategy leverages several competitive strengths that Tenax believes provide it with an advantage over many of its competitors. Tenax offers customers the opportunity to combine sourcing and modification of aircraft with operations and logistics support, which provides customers with a one-stop source for meeting their aviation requirements. Tenax believes its balance sheet and access to financing enable it to purchase more expensive aircraft and fund more expensive modifications than most of its smaller competitors. Smaller competitors often do not have the resources or relationships to shape mission requirements. In addition, many large OEMs and prime contractors are not interested in supplying and operating aircraft under COCO arrangements, limiting their participation in the market for many of the products and services Tenax provides its customers. Tenax’s technical team brings significant specialized expertise in modifying aircraft to meet special mission requirements that smaller competitors do not have. Tenax has experience and a proven performance track record that make it difficult for new entrants to compete for contracts. Each of these strengths give Tenax a competitive advantage.

Compelling Value Proposition for Customers

Tenax enables customers to outsource important aviation missions to a specialized provider who delivers superior, and usually less expensive, outcomes compared to direct ownership and operation of aircraft. By providing aircraft operations for a fee, Tenax reduces customers’ upfront capital requirements, opens up operations and maintenance (“O&M”) funds as a funding source, improves customers’ operational readiness and allows them access to modern, mission-configured aircraft without long procurement timelines. Tenax’s integrated model, combining aircraft sourcing, modification, operations and maintenance, provides customers with a single point of out-sourcing.

125

Table of Contents

Highly Experienced Team with Specialized Expertise

Tenax’s technical teams bring extensive experience and expertise, providing an advantage when guiding customers through the complexities of fulfilling the customer’s requirements. This expertise includes developing operational specifications, selecting the right airframes, performing modifications and integrating advanced sensors. Tenax’s leadership team includes former U.S. military general officers and special operations commanders with significant special mission experience. These relationships help Tenax understand customer requirements sooner and better, giving Tenax more time to meet delivery requirements.

Tenax’s operational expertise includes logistics planning, maintenance support, parts sourcing and operating in demanding environments. This sometimes involves sustaining operations in locations outside the United States where access to parts, maintenance facilities and qualified personnel can be challenging. These capabilities and specialized technical knowledge give Tenax a competitive advantage. Tenax has a network of vetted engineering and modification partners that provide Tenax with flexible capacity while maintaining quality standards.

Operational Capabilities Necessary for Special Mission Work

Tenax’s leadership and technical teams bring extensive technical, contracting, special operations and aviation operations experience that provide Tenax with an advantage over many of its competitors, particularly larger aerospace and defense contractors who typically do not offer aviation operations. Tenax has spent more than two decades developing the expertise, focus, culture, clearances and partnerships required to execute reliably in special mission environments. Currently, Tenax maintains 90%+ operational availability across a 43-aircraft fleet, demonstrating consistent execution despite often challenging conditions.

Tenax has a proven track record of on-time, on-budget delivery of significantly modified airframes, earning a reputation for high-quality equipment and services. Over its history Tenax has modified or overseen modification of more than 100 aircraft. This track record has fostered cooperative, trusted and longstanding relationships with key decision-makers across Tenax’s customer base. In government contracting markets, past performance is among the most heavily weighted factors in contract award decisions. Tenax’s demonstrated operational capabilities and reliability have been key drivers of its success in both initial contract awards and recompetes. Once a contract is won, the customer’s investment in a uniquely modified aircraft creates significant switching costs. As a result, the original contract winner has an advantage in retaining the business and winning recompetes for as long as the aircraft and sensor technology continue to meet the customer’s requirements.

Growth Strategies

Tenax has demonstrated its ability to grow with current customers and find business with new customers and it expects to continue to do so in the future. Tenax takes deliberate steps to ensure it continues to satisfy its customers. For example, prior to the recent recompete of the U.S. Forest Service contract, Tenax upgraded its aircraft under the contract from the Beechcraft King Air C90 to the Beechcraft King Air 250 which helped ensure a recompete win while increasing the revenue and profitability from the higher performing, more expensive aircraft. In addition, the U.S. Forest Service has increased its ASM fleet size in the last year from fifteen to sixteen aircraft and has indicated an interest in further increasing the fleet size up to twenty aircraft.

Tenax has a strong history of recompete success. Since 2004, when a mission was continuing, Tenax has won twenty-three out of twenty-four recompetes, and there were only two instances of option years not being exercised. This is a critical metric in government contracting markets where past performance and operational readiness are primary drivers of award decisions. Tenax intends to continue pursuing recompetes and expanding into new contracts with current customers.

Through the successful efforts of Tenax’s business development team, Tenax has won significant new business in the last year, including a standoff jammer (“CAS-SOJ”) contract with the U.S. Navy, a mid-altitude ISR contract with the U.S. Army, a law enforcement contract with the state of Florida and a military contract for a multi-purpose Gulfstream aircraft. Tenax believes there are many opportunities for it to expand into special mission areas that it does not currently serve, such as firefighting helicopters, adversary simulation, in-flight refueling aircraft, military personnel transport, maritime patrol, range-clearing, Casualty Evacuation/Medical Evacuation and unmanned special mission aircraft.

126

Table of Contents

Tenax expects to augment its internal growth through acquisitions. Tenax maintains an active pipeline of strategic acquisition opportunities with the goal of boosting growth while reducing customer/contract concentration and adding scale to Tenax’s existing business. Tenax is focused on acquiring businesses that employ different aircraft types or roles in Tenax’s current markets, similar aircraft types or roles in foreign markets, and bringing modification and other purchased services in-house. Following completion of the merger, Tenax will also focus on expanding AIR’s presence in aerospace parts and components manufacturing.

Customers

Most of Tenax’s customers are part of the U.S. government, including the U.S. Army’s Geospatial Center, the U.S. Forest Service, the Department of Justice, the Federal Bureau of Investigation, the U.S. Navy and the intelligence community. Other customers include foreign governments, state and local governments and commercial customers. Tenax currently has only one significant foreign government customer, a Five Eyes partner nation, but Tenax believes there are many opportunities for Tenax to develop new international customers for its products and services. Tenax has long-standing customer relationships. The average tenure of Tenax’s six largest customers is about 14 years.

In the first quarter of 2026, Tenax’s largest customer accounted for 27% of Tenax’s revenues. However, with the U.S. Navy’s CAS-SOJ contract and other new business coming online in 2026, customer concentration is expected to continue to decline in 2026 and thereafter.

Competition

Competitors in Tenax’s markets include small specialty operators, mid-sized services firms and large defense contractors. Small specialty operators mostly only offer one or two airframe options, which often are no longer in production, and respond to government RFP’s after they have been issued rather than helping shape requirements. Mid-size services firms and large defense contractors prefer offering services or products rather than COCO aviation operations. Tenax’s business model seeks to bridge the gap, combining the focus of a specialist with the ability to help shape solutions to a customer’s requirements and the ability and willingness to acquire expensive assets and accept operating risk.

Aviation Assets

Tenax maintains and operates a fleet of special mission aircraft that it believes is newer, on average, than many competitors’ fleets and includes mostly OEM-supported aircraft that are less than twenty years old with good secondary-market liquidity. As of June 30, 2026, Tenax’s fleet included 43 aircraft. Tenax avoids purchasing aircraft more than twenty years old to ensure up-to-date systems, high operational readiness and readily available parts. Tenax directly maintains or manages maintenance for the majority of its fleet and performs or oversees modifications and sensor integration through DST and its trusted partner network.

Tenax typically acquires aircraft only after a contract is awarded and begins collecting monthly fees upon award, including during the modification period. Tenax’s customers typically pay directly for modification costs or Tenax is reimbursed through monthly payments in the first one to two years of the contract. This mitigates the risk of Tenax not being fully reimbursed for modification costs if a contract ends earlier than expected. Tenax identifies contract opportunities through agency access and procurement tools and engages customers early to help ensure the best solution is available to meet the customer’s requirements. Tenax’s contracts are all firm fixed-price contracts with inflation escalators. Tenax’s costs are primarily made up of labor, aircraft parts, other maintenance costs and depreciation. Tenax typically does not pay for fuel to operate its aircraft. Very little of what Tenax buys is sourced overseas, so tariffs and currency exchange rates have not and should not in the future materially affect Tenax’s profitability. As a result, Tenax’s costs do not vary significantly over the short term and have tended to increase at or near U.S. core inflation rates. In the past, Tenax’s contract price escalators have adequately covered increases in costs over time. Tenax sources firm fixed-price bids from its vendors and develops pricing that reflects aircraft and modification costs, operational costs and complexity, contract length and risk factors associated with fulfilment, early termination and recompetition. As contracts approach renewal or termination, Tenax prepares redeployment or de-modification plans and disposes of aircraft if redeployment within a reasonable time is unlikely.

Seasonality

Most of Tenax’s business is not seasonal. The only part of Tenax’s business that is seasonal is Tenax’s U.S. Forest Service business, which is stronger in the second and third quarters than the first and fourth quarters. Various other factors can affect the distribution of Tenax’s revenue between accounting periods, including the timing of awards, customer acceptance of products and services, contract phase-ins, contract completions and the availability of customer funding. Weather and natural phenomena can also temporarily affect the performance of its services and timing of its revenues and profitability.

The U.S. government’s fiscal year ends on September 30th. U.S. government agencies may award extra task orders or complete other contract actions in the month or two leading up to the end of its fiscal year in order to avoid the loss of unexpended fiscal year funds, which may favorably affect Tenax’s third fiscal quarter results.

Regulatory Environment

Aviation Regulation

Tenax’s operations are subject to U.S. civil aviation regulations, including the FAA, military and other airworthiness authorities for aircraft operations, maintenance and modifications. Tenax develops and holds supplemental type certificates and executes integration and modification work internally and through approved third parties. These approvals and certifications constitute substantive barriers to entry and are essential to Tenax’s ability to provide fully configured, mission-ready aircraft.

Government Procurement Rules

U.S. government procurement requirements and rules also shape Tenax’s business. Tenax must comply with a range of federal laws and regulations governing the formation, administration and performance of government contracts. Key regulations include the Federal Acquisition Regulations, Defense Federal Acquisition Regulations, the Truth in Negotiations Act, the Procurement Integrity Act, the Civil False Claims Act and Cost Accounting Standards. Tenax is subject to periodic government audits of its costs, internal controls and cybersecurity practices, and must ensure that costs charged to government contracts are properly classified and allocated. Tenax must maintain facility clearances and security clearances for many of its personnel in order to perform work on some of Tenax’s contracts.

Import/Export Regulations

Tenax is subject to extensive import and export controls administered by the U.S. government. The U.S. Department of Commerce and the U.S. Department of State regulate the export, re-export and re-transfer of controlled goods and technologies, and may require Tenax to obtain authorization before exporting certain items, including aircraft, engines, parts, components, avionics, radars and other sensors. Applicable export control laws include the Arms Export Control Act, the International Traffic in Arms Regulations and the Export Administration Regulations, which restrict the export of defense and dual-use products and technical data to certain countries. The U.S. Department of Homeland Security, through U.S. Customs and Border Protection, enforces regulations governing the import of aviation-related products into the United States.

Tenax must also comply with trade sanctions laws and regulations administered by OFAC. Tenax is prohibited from transacting with individuals and entities appearing on OFAC’s “Specially Designated Nationals List” and must monitor its operations, customers and counterparties for compliance with applicable sanctions regimes.

Anti-Corruption Regulations

Tenax’s operations are subject to anti-corruption laws in the United States and in the foreign jurisdictions in which it does business. These include the Foreign Corrupt Practices Act, the U.S. domestic bribery statute and the U.S. Travel Act, among others. These laws generally prohibit Tenax, its employees and its intermediaries from authorizing or providing improper payments or anything of value to government officials or other people in order to obtain or retain business or secure a business advantage.

Environmental Regulations

Tenax is subject to federal, state and local environmental laws and regulations governing the discharge and emission of substances into the environment, the disposal of hazardous waste and the remediation of contaminants. Tenax is also subject to workplace safety requirements under the Occupational Safety and Health Act of 1970, including standards for the handling of hazardous and toxic substances and the treatment, disposal or storage of hazardous waste.

Contracts

Tenax’s business with the U.S. government is typically funded with O&M funds and, therefore, must be structured as a one-year award with option years, rather than multi-year awards, which are prohibited under O&M funding rules. In addition, U.S. government departments and agencies retain broad rights under all U.S. government contracts to terminate on sixty days’ notice, with or without cause. The single-year funding commitment and sixty-day right to terminate present risks to Tenax. Tenax believes it is adequately compensated for those risks with its pricing and asset acquisition and other risk mitigation strategies. Tenax’s role is usually as a prime contractor, but it also partners as a subcontractor to prime contractors.

Tenax concentrates on enduring missions that require significant airframe modification and sustained operational support, which Tenax believes increases the probability that option years will be exercised. Since 2004, Tenax has won twenty-three out of twenty-four recompetes and, when a mission was continuing, there have been only two instances of a non-exercised option year. Tenax’s contract portfolio includes many long term contracts such as the U.S. Forest Service aerial firefighting mission which Tenax has supported for nearly sixteen years and has successfully recompeted five times. Tenax has supported the U.S. Army’s HR3D program for nearly nine years while growing the program’s scope and winning multiple recompetes.

Legal Proceedings

Tenax may become involved in legal proceedings, including, but not limited to, matters in connection with its contracts, employment matters and regulatory investigations and inquiries, in the ordinary course of its business. Although Tenax is unable to predict with certainty the eventual outcome of any litigation, regulatory investigation or inquiry, it does not currently believe, based on information currently available, that resolution of its current and any threatened legal proceedings will, individually or in the aggregate, have a material adverse effect on its competitive position, results of operation, financial condition or liquidity. Given the inherent unpredictability of these types of proceedings, however, it is possible that future adverse outcomes could have a material adverse effect on Tenax’s financial results.

Aerial Firefighting

Tenax serves as the prime contractor to the U.S. Forest Service for the ASM program. The ASM program includes a fleet of 16 aircraft that deliver approximately 3,900 flight hours annually and maintain operational readiness of over 99 percent as of March 31, 2026. These aircraft conduct both Lead Plane and Airborne Fire Management roles. The Lead Plane role involves laying down a smoke trail showing tanker aircraft where to drop their fire retardant. The Airborne Fire Management role involves coordinating communications over the fire. Tenax equips these aircraft with special mission radios, infrared cameras and satellite communications to support coordinated air attack operations. Tenax also supports the U.S. Forest Service and CAL FIRE with additional aircraft for other roles, including precision aerial fire mapping and tactical EO/IR support. These programs are structured with different levels of support for the customer, including contracts where Tenax supplies only the aircraft and other programs where Tenax supplies the aircraft, pilots, maintenance and sensor operations.

Mapping and Multi-Mission Aircraft

Tenax operates aircraft that combine high-altitude mapping and ISR capabilities. Under the U.S. Army Geospatial Center’s HR3D program, Tenax provides aircraft to various U.S. Combatant Commands such as AFRICOM and INDOPACOM. These aircraft carry various combinations of high-altitude LiDAR sensors, foliage-penetrating sensors, high-definition photographic sensors, EO/IR sensors with full motion video and SIGINT sensors. These aircraft are capable of mapping up to 1,000 square miles per day. While mapping is the primary mission, these aircraft are configured to fulfill ISR roles. Under the HR3D program, Tenax provides pilots and maintenance personnel under COCO arrangements, including in locations outside the continental U.S. Tenax also provides aircraft for the FBI Critical Response Group to support global counterterrorism missions and aircraft for the U.S. Navy’s continental U.S.-based training and transportation needs.

Intelligence, Surveillance and Reconnaissance

Tenax conducts SIGINT, Electronic Intelligence, Electronic Warfare and Image Intelligence (or EO/IR) missions for certain of its customers. Tenax provides aircraft for these purposes to the U.S. government and to a Five Eyes partner nation, the latter aircraft configured with SIGINT sensors and EO/IR full motion video with Tenax providing flight operations and maintenance support. Tenax also supports maritime patrol and border surveillance for the Florida Department of Law Enforcement by providing aircraft equipped with EO/IR, radar, Starlink communications, a proprietary mission control system and special law enforcement radios. Tenax also provides the U.S. Army with two aircraft for its medium-altitude ISR mission focused on the detection and capture of foreign intelligence personnel and other adversaries.

Sensor Integration, Modification, Testing and Training and Logistics Support

Tenax, through DST, provides aircraft configured to accept a variety of U.S. government-owned SIGINT sensors for characterization, calibration and testing. DST also provides sensor operator training on aircraft and in classrooms. DST’s training curricula include flight operations, aircraft maintenance and aircraft and sensor operations instruction. DST procures, modifies and, in some cases, operates ISR and SIGINT aircraft for customers in the intelligence and law enforcement communities. Most of DST’s contracts are sole sourced and classified.

Recent Developments

Aircraft Fleet Optimization

In the past, when the Company held an aircraft for sale it did not reclassify it as an asset held for sale. However, in the first quarter of 2026, the Company adopted compliance with ASC Topic 205-20 and ASC Topic 360-10, under which long-lived assets are classified as held for sale once they meet specified criteria, including management’s commitment to a plan to sell the assets and the immediate availability of the assets for sale. Accordingly, during the three months ended March 31, 2026, we reclassified three aircraft that met all criteria to perform a reclassification from property and equipment, net, to current “Assets held for sale” on our condensed consolidated balance sheet. As of March 31, 2026, these assets had an aggregate carrying amount of $27,077,828, compared to $0 as of December 31, 2025. As of June 30, 2026, the remaining amount of assets held for sale is $900,000, following the sale of two of the aircraft.

As part of the reclassification accounting, we measured these assets at the lower of their carrying amount or fair value less costs to sell. Because the estimated fair value less costs to sell exceeded their carrying value, no impairment charges were recognized during the three months ended March 31, 2026. Management evaluated this planned disposition and determined that it does not represent a strategic shift with a major effect on our operations or financial results. Consequently, the transaction does not qualify as a discontinued operation; the historical operating results of these aircraft will remain within continuing operations through the date of disposal.

Debt Recapitalization

On January 7, 2026, the Company purchased the equity held by Bain Capital Management, a credit and equity provider behind the acquisition of the Company in 2018. To provide the funding for the equity purchase, we amended our Second Amended and Restated First Lien Credit Agreement (the “First Lien Agreement”) to provide for a $200,000,000 term loan, a $40,000,000 Delayed Draw Term Loan (“DDTL”) #1, a $60,000,000 DDTL #2 and a $30,000,000 revolving line of credit. As of March 31, 2026, the outstanding balance on our revolving credit line was $6,530,720 (compared to $6,650,000 as of December 31, 2025), with a variable interest rate of 7.02%, and we drew $48,057,153 under DDTL #2 during the quarter. The amended First Lien Agreement matures at the earliest of January 7, 2031, twelve months prior to the maturity of the Subordinated Term Loan, or six months prior to the maturity of the Second Lien Agreement. In addition, the Company entered into a new Second Lien Credit Agreement (the “Second Lien Agreement”) with an investment firm, securing $30,000,000 of debt maturing on July 7, 2031, with principal repayment due in full at maturity.

Additionally, on January 7, 2026, the Subordinated Term Loan (which originally carried a January 4, 2024, maturity) was refinanced with a different lender, extending its maturity date to January 7, 2032, with the principal due at maturity. For the three months ended March 31, 2026, capitalized interest was $289,932, compared to $0 for the three months ended March 31, 2025. Following the refinancing, the outstanding balance on the Subordinated Term Loan increased to $40,125,791 as of March 31, 2026, from $29,471,221 as of December 31, 2025, while the interest rate decreased to 15.00% at March 31, 2026, from 18.09% as of December 31, 2025.

Critical Accounting Policies and Estimates

The preparation of financial statements in accordance with generally accepted accounting principles in the U.S. requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. The financial statements include estimates based on currently available information and our judgment as to the outcome of future conditions and circumstances. Significant estimates in these financial statements include revenue recognition and the valuation of long-lived assets. Changes in the status of certain facts or circumstances could result in material changes to the estimates used in the preparation of the financial statements and actual results could differ from the estimates and assumptions. We believe that the following discussion addresses our critical accounting policies which require management’s most difficult, subjective and complex judgments, often as a result of the need to make estimates about the effect of matters that are inherently uncertain.

Revenue Recognition

Tenax is a provider of special mission aircraft and related services to U.S. government and commercial customers. As a result of its business model, the Company derives revenue from both contracts for services and products and aircraft leasing arrangements, which are accounted for under Topic 606, and ASC Topic 842, “Leases” (“Topic 842”), as applicable.

Tenax recognizes service and product income when we satisfy performance obligations under the terms of our contracts, and control of our products is transferred to our customers in an amount that reflects the consideration we expect to receive from our customers in exchange for those products. This process involves identifying the customer contract, determining the performance obligations in the contract, determining the contract price, allocating the contract price to the distinct performance obligations in the contract and recognizing revenue when the performance obligations have been satisfied. A performance obligation is considered distinct from other obligations in a contract when it (a) provides a benefit to the customer either on its own or together with other resources that are readily available to the customer and (b) is separately identified in the contract. Tenax considers a performance obligation satisfied once we have transferred control of a good or by transferring control over a product to a customer, meaning the customer has the ability to use and obtain the benefit of the product.

Service and product income is largely related to products or services performed under government contracts. Service and product income is recognized over time. The Company’s wholly owned subsidiary, DST, provides specially modified aircraft for aerial sensor testing, training and live operations. DST also provides unmanned aircraft systems and maritime services and logistical support for these and other special mission aircraft operations. Additionally, DST provides aircraft modification services to customer aircraft. Because DST has the substantive right of substitution, contracts with DST’s customers do not represent leases under Topic 842. Revenues are recognized in accordance with Topic 606. For performance obligations to provide services that are satisfied over time, the Company recognizes revenue based on the right to invoice method (i.e., based on the right to bill the customer), which corresponds with, and thereby best depicts, the transfer of control to the customer.

For contracts with embedded leases, we have elected the practical expedient to not separate lease and non-lease components described in Note 1(n) “Leases-Lessee Arrangements” in the notes to our condensed consolidated financial statements beginning on page F-67 of this proxy statement/prospectus for operating leases that meet certain conditions. These services are principally performed under fixed-price contracts. Revenue on fixed-price service contracts is generally recognized in accordance with the performance obligations over the contract service period. For our sales-type leases, the lease components are accounted for under Topic 842 and the non-lease components (i.e., modification, operations and maintenance services) are accounted for under

133

Table of Contents

Topic 606. For our contracts with multiple performance obligations, the Company allocates the transaction price to each performance obligation based on the relative standalone selling price of the product or service underlying each performance obligation. The standalone selling price represents the amount for which the Company would sell the product or service to a customer on a standalone basis (i.e., not sold as a bundle with any other products or services). These government contracts, of which the Company is the subcontractor, typically prices contract deliverables based on the Company’s estimated or actual costs plus a reasonable profit margin. As a result, the standalone selling prices of the products and services in these contracts are typically equal to the selling prices stated in the contract, thereby eliminating the need to allocate (or reallocate) the transaction price to multiple performance obligations. For the performance obligations to provide services that are satisfied over time, the Company recognizes revenue either on a straight-line basis, the percentage of completion cost-to-cost method or based on the right-to-invoice method, depending on which method best depicts transfer of control to the customer.

Contract costs include all direct material and labor costs and those indirect costs related to contract performance, such as indirect labor, supplies, tools and repairs. Selling, general and administrative costs are charged to expense as incurred. Provisions for estimated losses on uncompleted contracts are made in the period in which such losses are determined. Changes in job performance, job conditions, estimated profitability and final contract settlements may result in revisions to cost and income and are recognized in the period in which such revisions may be determined.

Tenax’s contracts vary in length and often include a base-year service period followed by option-years that may be exercised annually. For base-year service period contracts, assets and liabilities are classified as current because the contract related items in the consolidated balance sheets have realization and liquidation periods of less than one year.

Because of the inherent uncertainties in estimating costs and revenues, it is at least reasonably possible that the estimates used could change in the near term. See Note 1(k) “Revenue Recognition” in the notes to Tenax’s condensed consolidated financial statements beginning on page F-65 of this proxy statement/prospectus for additional information regarding Tenax’s revenue recognition policies.

Valuation of Long-Lived Assets

Tenax evaluates the recoverability of the carrying value of long-lived assets, such as property and equipment and purchased intangible assets subject to amortization, whenever events or circumstances indicate the carrying amount may not be recoverable. Conditions that may indicate recoverability include, but are not limited to, a significant adverse change in customer demand or business climate that could affect the value of an asset, or an adverse action or assessment by a regulator. If a long-lived asset is tested for recoverability and the undiscounted estimated future cash flows expected to result from the use and eventual disposition of the asset is less than the carrying amount of the asset, the asset cost is adjusted to fair value, and an impairment loss is recognized as the amount by which the carrying amount of a long-lived asset exceeds its fair value. See Note 1(g) “Long Lived Asset Impairment” in the notes to Tenax’s condensed consolidated financial statements beginning on page F-64 of this proxy statement/prospectus for additional information regarding Tenax’s valuation of long-lived assets.

Revenues increased by $8.2 million, or 24.9%, for the quarter ended March 31, 2026 as compared to the quarter ended March 31, 2025.

Revenues increased in the first quarter of 2026 compared to 2025, primarily due to the impact of new contracts and the successful recompete of existing programs, partially offset by a decline in modification income. The main drivers for revenue growth were the addition of a new U.S. Navy contract with prime contractor ATAC, a Textron company, a new contract with the Florida Department of Law Enforcement, a new U.S. Army contract with prime contractor HII Mission Technologies Corp. and the solid performance of Tenax’s legacy programs. In contrast, service and product revenue decreased, reflecting the completion of modifications on two Gulfstream GV aircraft, partially offset by contributions from newly awarded ISR contracts with a Five Eyes partner nation and the U.S. Army.

%

Cost of revenues increased by $2.5 million, or 17.3%, for the quarter ended March 31, 2026 as compared to the quarter ended March 31, 2025.

Direct costs increased primarily due to higher business activity, largely driven by the execution of newly awarded contracts. Increased depreciation expense reflects the commencement of depreciation for two Gulfstream aircraft following the completion of their modifications.

Gross Profit

Gross profit increased by $5.7 million, or 30.8%, for the quarter ended March 31, 2026 as compared to the quarter ended March 31, 2025. The contribution of new contracts, along with the solid execution on the existing programs, supported the overall growth in gross profit.

General and Administrative Expenses

General and administrative expenses increased by $1.8 million, or 41.5%, for the quarter ended March 31, 2026 as compared to the quarter ended March 31, 2025. The primary reason for the increase is related to the growth in indirect functions to manage the business growth, including contracts, accounting, financial systems and IT infrastructure, business development and legal expenses.

Depreciation and Amortization

Depreciation and amortization increased in the first quarter of 2026 compared to 2025 as a result of the increase in our property and equipment base.

Net Interest Expense

Interest expense increased by $3.0 million, or 58.7%, for the quarter ended March 31, 2026 compared to the same period in 2025, primarily due to higher total debt as a result of the recapitalization and the purchase of two Bombardier Challenger 650 aircraft.

Revenues increased by $4.8 million, or 3.8%, for the year ended December 31, 2025, in comparison to the year ended December 31, 2024.

Revenues increased in 2025 primarily due to higher activity and the impact of the new contracts on our aerial firefighting programs, partially offset by a decline in modification income.

Aircraft rental and flight-hour revenue increased, driven by the addition of an aircraft to the U.S. Forest Service ASM contract, along with contractual rate increases resulting from the fleet upgrade on that program. The newly awarded contracts for testing and training and aerial firefighting missions also provided incremental revenue and additional flight-hour activity.

Service and product revenue increased due to newly awarded ISR contracts with a Five Eyes partner nation and the U.S. Army. Higher rates were also negotiated on existing testing and training service contracts. These increases reflect both expanded customer relationships and improved pricing terms on select service offerings. Modification income declined as major mapping and ISR modifications were completed on two Gulfstream GV aircraft transitioning into the operations phase after a multi-year modification period.

-5.9

%

Cost of revenues decreased by $3.9 million, or -5.9%, for the year ended December 31, 2025, in comparison to the year ended December 31, 2024.

Direct costs significantly decreased in 2025, as a result of the transition within the AGC HR3D program. With the addition of two Gulfstream GV aircraft to our fleet, the operations being performed by the G-IV aircraft ceased at the end of 2024. The transition significantly reduced operating expenses compared to the prior year due to the GV aircraft undergoing modification.

Gross Profit

Gross profit increased by $8.8 million, or 14.0%, for the year ended December 31, 2025, in comparison to the year ended December 31, 2024. The increase in scope, overall activity and the contribution of new contracts drove revenue growth across multiple programs. Gross profit further benefited from a reduction in operational costs.

General and Administrative Expenses

General and administrative expenses increased by $2.9 million, or 15.8%, for the year ended December 31, 2025, in comparison to the year ended December 31, 2024. The primary reason for the increase is related to legal expenses, increased business development efforts and supporting the growth in services contracts.

Depreciation and Amortization

Depreciation increased in 2025 as a result of the increase in our property and equipment base.

Change in Value of Contingent Consideration

Change in value of contingent consideration decreased by $0.8 million for the year ended December 31, 2025, in comparison to the year ended December 31, 2024. The decrease is driven by a true-up of an earn-out liability based on actual financial results.

Net Interest Expense

Interest expense decreased by $0.9 million, or -4.1%, for the year ended December 31, 2025, in comparison to the year ended December 31, 2024, supported by the drop in the SOFR rate from 2024 to 2025.

Revenues increased by $13.5 million, or 11.7%, for the year ended December 31, 2024, in comparison to the year ended December 31, 2023.

Revenues increased in 2024, driven primarily by higher activity on the AGC HR3D program, as the company’s second GV aircraft was on contract for the full year compared to a partial year in 2023, and the majority of mapping and ISR modification revenues for both aircraft were recognized. Additional revenue growth was generated by the fleet upgrade and increased operational activity under the U.S. Forest Service ASM contract.

Cost of revenues increased by $8.7 million, or 15.3%, for the year ended December 31, 2024, in comparison to the year ended December 31, 2023.

Consistent with the increase in revenues noted above, cost of revenues increased during this period primarily due to higher activity on the AGC HR3D program. During 2024, Tenax temporarily operated three aircraft under contract as part of the transition associated with the upgrade from one Gulfstream G-IV aircraft to two Gulfstream GV aircraft, resulting in elevated operating costs.

Depreciation increased in 2024 as a result of the increase in our property and equipment base.

Gross Profit

Gross profit increased by $4.7 million, or 8.2%, for the year ended December 31, 2024, in comparison to the year ended December 31, 2023. The primary reason for the increase is the higher activity on the AGC HR3D program, along with the higher contribution coming from fleet upgrades and additional flight operations.

General and Administrative Expenses

General and administrative expenses increased by $2.3 million, or 14%, for the year ended December 31, 2024, in comparison to the year ended December 31, 2023. The increase was driven primarily by higher personnel-related costs attributable to incremental headcount added to support expanding operations.

Table of Contents

Depreciation and Amortization

Depreciation and amortization decreased by $1.1 million, or -14.2%, for the year ended December 31, 2024, in comparison to the year ended December 31, 2023. The decrease is driven by a reduction in the amortization amount due to the declining balance of customer relationship intangible assets.

Change in Value of Contingent Consideration

Change in value of contingent consideration decreased by $2.4 million for the year ended December 31, 2024, in comparison to the year ended December 31, 2023. The decrease is driven by a true-up of an earn-out liability based on actual financial results.

Non-GAAP Financial Measures

Although we believe that net income or loss, as determined in accordance with GAAP, is the most appropriate earnings measure, we use EBITDA and Adjusted EBITDA as key profitability measures to assess the performance of our business. We believe these measures help illustrate underlying trends in our business and use the measures to establish budgets and operational goals, and communicate internally and externally, in managing our business and evaluating its performance. We also believe these measures help investors compare our operating performance with its results in prior periods in a way that is consistent with how management evaluates such performance.

Each of the profitability measures described below is not recognized under GAAP and does not purport to be an alternative to net income or loss determined in accordance with GAAP as a measure of our performance. Such measures have limitations as analytical tools, and should not be considered in isolation or as substitutes for our results as reported under GAAP. EBITDA and Adjusted EBITDA exclude items that can have a significant effect on our profit or loss and should, therefore, be used only in conjunction with our GAAP profit or loss for the period. Our management compensates for the limitations of using non-GAAP financial measures by using them to supplement GAAP results to provide a more complete understanding of the factors and trends affecting the business than GAAP results alone. Because not all companies use identical calculations, these measures may not be comparable to other similarly titled measures of other companies.

EBITDA and Adjusted EBITDA

EBITDA is a non-GAAP financial performance measure calculated by adding income taxes, interest, amortization and depreciation back to the company’s net income or net loss. EBITDA eliminates potential differences in performance caused by variations in capital structures (affecting financing expenses), the cost and age of tangible assets (affecting relative depreciation expense) and the extent to which intangible assets are identifiable (affecting relative amortization expense).

Adjusted EBITDA is a non-GAAP profitability measure that represents EBITDA before certain items that are considered to hinder comparison of the performance of our businesses on a period-over-period basis or with other businesses. During the periods presented, we exclude from Adjusted EBITDA certain costs that are required to be expensed in accordance with GAAP, including change in value of contingent consideration, change in fair value of interest rate cap, swap, warrants and transaction costs. Our management believes that the inclusion of supplementary adjustments to EBITDA applied in presenting Adjusted EBITDA are appropriate to provide additional information to investors about certain material non-cash items and about unusual items that we do not expect to continue at the same level in the future.

Operating Activities

Net cash provided by operating activities was $12.5 million for the quarter ended March 31, 2026, compared to $3.6 million for the quarter ended March 31, 2025, which represents an increase of $8.9 million. The increase was mainly driven by business growth and favorable changes in working capital, partially offset by payments related to contingencies. Additionally, the cash contribution of programs awarded during the latter part of 2025 drove the increase, along with the unwinding of deferred revenue following the completion of multi-year modification work on two Gulfstream GV aircraft.

Investing Activities

Net cash used in investing activities was $17.5 million for the quarter ended March 31, 2026, compared to $7.6 million for the quarter ended March 31, 2025, which represents an increase of $9.8 million. This increase was mainly driven by the purchase of an additional aircraft for the execution of a new contract with the U.S. Navy, with ATAC as the prime contractor, as well as for the related deposits towards contract required modifications. This was partly offset by the sale of a King Air B200 aircraft.

Financing Activities

Net cash provided by financing activities was $5.3 million for the quarter ended March 31, 2026, compared to $6.4 million for the quarter ended March 31, 2025. The comparative decrease in cash flows provided by financing activities was primarily driven by cash outflows related to the repurchasing of member units and the related transaction costs.

Operating Activities

Net cash provided by operating activities was $16.4 million for the year ended December 31, 2025, compared to $44.8 million for the year ended December 31, 2024, which represents a decrease of $28.4 million. Cash flows from operating activities decreased mainly because of the unwinding of deferred revenue following the completion of multi-year modification work on two Gulfstream GV aircraft, and a temporary increase in working capital primarily driven by the start of new programs.

Net cash provided by operating activities was $44.8 million for the year ended December 31, 2024, compared to $17.4 million for the year ended December 31, 2023, which represents an increase of $27.4 million. Cash flows from operating activities increased due to the scope increase in the AGC HR3D program, along with the higher contribution from aerial firefighting programs.

Investing Activities

Net cash used in investing activities was $67.1 million for the year ended December 31, 2025, compared to $7.8 million for the year ended December 31, 2024, which represents an increase of $59.2 million. This increase was mainly driven by the purchase of additional aircraft to support new programs.

Net cash used in investing activities was $7.8 million for the year ended December 31, 2024, compared to $52.6 million for the year ended December 31, 2023, which represents a decrease of $44.8 million. Cash flows from investing activities declined because the large aircraft purchases for newly awarded contracts that drove higher outflows in 2023 were completed in that year, and no aircraft acquisitions occurred in 2024.

Financing Activities

Net cash provided by financing activities was $50.6 million for the year ended December 31, 2025, compared to $41.0 million used for the year ended December 31, 2024. The significant increase in cash flow provided by financing activities was driven by additional borrowing required for the acquisition of new aircraft, fleet upgrades and additional capital expenditures invested in newly awarded contracts.

Net cash used in financing activities was $41.0 million for the year ended December 31, 2024, compared to $35.7 million provided for the year ended December 31, 2023. The increase in cash used in financing activities reflects the Company’s significant reduction of debt as a result of strong operating cash generation and proceeds from the sale of aircraft coming off contract.

Quantitative and Qualitative Disclosures About Market Risk

Tenax is subject to market risks in the ordinary course of business. Market risk refers to the potential losses arising from adverse changes in market rates and prices. Tenax is primarily exposed to market risk associated with changes in interest rates on its variable-rate debt obligations.

Interest Rate Risk

Tenax is exposed to interest rate risk primarily through borrowings under its variable-rate debt facilities. As of March 31, 2026, Tenax had approximately $294.6 million of variable-rate debt outstanding, consisting of its First Lien term loan, delayed draw term loans and revolving line of credit. Borrowings under these facilities bear interest based on adjusted SOFR plus an applicable margin or a base rate plus an applicable margin. The applicable variable interest rates on these borrowings were approximately 7.02% to 7.13% as of March 31, 2026. Tenax also had fixed-rate debt outstanding, including a $30.0 million Second Lien term loan bearing interest at 11.50% and a $42.8 million subordinated term loan bearing interest at 15.00% as of March 31, 2026.

Tenax uses interest-rate derivative instruments to mitigate a significant portion of its exposure to changes in market interest rates. As of March 31, 2026, Tenax had interest-rate cap agreements with notional amounts of $150.0 million and $75.0 million and an interest-rate swap agreement with a notional amount of $40.0 million. The aggregate notional amount of these instruments was $265.0 million, compared with approximately $294.6 million of variable-rate debt outstanding. The extent to which these instruments reduce Tenax’s interest-rate exposure depends on their respective strike rates, contractual terms and maturities and the amount and terms of the underlying variable-rate debt.

Tenax is currently evaluating its $150.0 million and $75.0 million interest-rate caps and $40.0 million interest-rate swap for potential designation in qualifying hedging relationships. Tenax intends to apply hedge accounting prospectively to any instrument that satisfies the applicable qualification criteria, including the requirement that the hedging relationship be expected to be highly effective in offsetting changes in cash flows attributable to the designated interest-rate risk. Until an instrument is formally designated and qualifies for hedge accounting, changes in its fair value will continue to be recognized in earnings.

A hypothetical 100-basis-point increase in market interest rates on Tenax’s variable-rate debt outstanding as of March 31, 2026 would increase interest expense by approximately $2.9 million annually and $0.7 million for a three-month period. This gross sensitivity does not reflect the potential offsetting effects of Tenax’s interest-rate caps and swap and, therefore, does not represent Tenax’s net interest-rate exposure.

On February 5, 2024, Tenax entered into a Non-Exclusive Aircraft Dry Lease Agreement with NTC Aviation, LLC (“NTC Aviation”), an affiliate of Thomas Foley, pursuant to which NTC Aviation agreed to lease to Tenax, on a non-exclusive, flight-by-flight basis and without crew, one Dassault Aviation model Falcon 2000EX aircraft. The agreement provides for an initial term of one year, with automatic renewals for additional one-year periods unless earlier terminated, and permits either party to terminate the lease without cause upon 30 days’ written notice. Under the agreement, Tenax is required to pay NTC Aviation hourly rent, including fuel, plus all other costs for flights conducted by Tenax, including ramp fees, landing fees, local fees, catering, entertainment, pilot fees and expenses, crew accommodations and post-flight maintenance, with any such expenses incurred by NTC Aviation to be billed monthly in addition to the hourly rent.

Beechcraft King Air

On December 19, 2024, Tenax entered into a separate Non-Exclusive Aircraft Dry Lease Agreement with NTC Aviation, pursuant to which NTC Aviation agreed to lease to Tenax, on a non-exclusive, flight-by-flight basis and without crew, one Beechcraft King Air C90GT aircraft. The agreement similarly provides for an initial term of one year, with automatic renewals for additional one-year periods unless earlier terminated, and permits either party to terminate the lease without cause upon 30 days’ written notice. Under the agreement, Tenax is required to pay NTC Aviation hourly rent, including fuel, plus all other costs for flights conducted by Tenax, including ramp fees, landing fees, local fees, catering, entertainment, pilot fees and expenses, crew accommodations and post-flight maintenance, with any such expenses incurred by NTC Aviation to be billed monthly in addition to the hourly rent.

Promissory Notes

James Linder, President of Tenax, Ignacio Ladegui, Executive Vice President and Chief Financial Officer of Tenax, and Alan Oswalt, Executive Vice President of Operations of Tenax, each of whom will serve as an executive officer of the combined company following the merger, hold membership interests in Tenax indirectly through Managers Equity, LLC (“Managers Equity”), a holding vehicle for Tenax management.

Each Individual Note is secured by a pledge of the related membership interests in Tenax and matures thirty days following the applicable borrower’s receipt of cash payment for the related membership interests in Tenax, except that 25% of the principal balance is due on the tenth anniversary of the issuance of the relevant Individual Note.

Between October 2022 and January 2024, Messrs. Linder, Ladegui and Oswalt contributed their membership interests in Tenax to Managers Equity in exchange for membership interests in Managers Equity. In connection with those contributions, Tenax assigned the Individual Notes to Managers Equity and each such Individual Note remains an outstanding obligation of Messrs. Linder, Ladegui and Oswalt payable to Managers Equity. Concurrently with these assignments, Managers Equity issued to Tenax a series of consolidated promissory notes, the currently operative of which is dated January 1, 2024 (the “Consolidated Note”) and has a principal amount of $2,062,500, of which $1,375,000 is attributable to Messrs. Linder, Ladegui and Oswalt and the balance of which is attributable to other members of Managers Equity, none of whom will serve as directors or executive officers of the combined company. The Consolidated Note accrues interest monthly at a rate of 4.0% on the unpaid principal balance, matures thirty days following Managers Equity’s receipt of cash payment for its membership interests in Tenax, is secured by a pledge of Managers Equity’s membership interests in Tenax, and requires that all cash provided by any members of

154

Table of Contents

Managers Equity toward payment of principal or accrued interest be remitted to Tenax immediately. Since January 1, 2024, no payments of principal or interest have been made on the Consolidated Note, and, as of June 30, 2026, the largest aggregate principal amount outstanding during such period was $2,062,500. As of June 30, 2026, $2,062,500 of principal and $385,924.66 of accrued and unpaid interest were outstanding under the Consolidated Note, of which $193,980.41, $66,027.40 and $12,479.45 were attributable to the amounts loaned in respect of the membership interests of Messrs. Linder, Ladegui and Oswalt, respectively.

In addition, between April 2024 and June 2026, Mr. Ladegui issued four unsecured promissory notes to Tenax Aerospace Holdings, LLC (“TAH”), a wholly owned subsidiary of Tenax, in the aggregate principal amount of $362,635, evidencing loans made to fund tax liabilities attributable to his indirect membership interest in Tenax, in lieu of tax distributions (collectively, the “Ladegui Tax Notes”). Each Ladegui Tax Note accrues interest annually at a rate of 4.0% on the unpaid principal balance and matures thirty days following Mr. Ladegui’s receipt of cash payment for his membership interest in Tenax, except that 25% of the principal balance is due on the tenth anniversary of the note if not previously repaid. Since the issuance of the Ladegui Tax Notes, no payments of principal or interest have been made on the Ladegui Tax Notes, and, as of June 30, 2026, the largest aggregate principal amount outstanding was $362,635. As of June 30, 2026, $379,540.04 in aggregate principal and accrued interest was outstanding under the Ladegui Tax Notes.

Prior to the completion of the merger, Tenax expects that the promissory notes described above will be repaid or transferred to one or more persons that will not be subsidiaries of AIR following the merger, and that any pledges or security interests securing such notes will be released in connection therewith, such that, following the closing, neither AIR nor any of its subsidiaries will hold indebtedness of any director or executive officer of the combined company.

DESCRIPTION OF AIR CAPITAL STOCK

The following description of AIR’s capital stock is not complete and is qualified in its entirety by reference to the articles and incorporation and bylaws of AIR. AIR encourages you to read AIR’s articles of incorporation, AIR’s bylaws and the applicable provisions of the NRS for additional information. The following information does not give effect to the proposed amendment to the articles of incorporation of AIR contemplated by the authorized shares proposal, the reverse stock split or any other stock split or similar transaction. Pursuant to the merger agreement, and subject to receipt of the requisite AIR stockholder approvals, AIR is obligated to file an amendment to the articles of incorporation of AIR, which will increase the number of authorized shares of AIR common stock from 20,000,000 to 200,000,000, and to effect the reverse stock split, which will subsequently decrease the number of authorized shares of AIR common stock to 40,000,000, in each case prior to the closing. The number of authorized shares of AIR preferred stock will remain 3,000,000. Please refer to the sections entitled “Proposal 2 — Approval of the Authorized Shares Proposal” and “Proposal 3 — Approval of the Written Consent Proposal” beginning on page 35 of this proxy statement/prospectus.

Authorized Capital Stock

AIR’s authorized capital stock consists of 20,000,000 shares of common stock, par value $0.001 per share, and 3,000,000 shares of preferred stock, par value $0.001 per share. As of March 31, 2026, there were 4,850,658 shares of common stock issued and outstanding and no shares of preferred stock issued and outstanding. The outstanding shares of AIR common stock are duly authorized, validly issued, fully paid and nonassessable.

Common Stock

Holders of our common stock are entitled to one vote per share on all matters submitted to a stockholder vote, including the election of directors. Holders of our common stock do not have cumulative voting rights. Therefore, holders of a majority of the shares of our common stock voting for the election of directors will be able collectively to elect all of the directors. Certain fundamental corporate changes, such as a liquidation, a merger or an amendment to our articles of incorporation, require the approval of the holders of certain proportions of the voting power of AIR common stock prescribed by the NRS and our articles of incorporation and bylaws for the particular corporate change. For the votes required to approve the amendments to our articles of incorporation to be voted on at the special meeting, see the sections entitled “Information About the Special Meeting — Proposal 2 — Approval of the Authorized Shares Proposal” and “Information About the Special Meeting — Proposal 3 — Approval of the Written Consent Proposal” beginning on page 35 of this proxy statement/prospectus. In the event of liquidation, dissolution or winding up of our company, either voluntarily or involuntarily, each outstanding share of our common stock will be entitled to share equally in our remaining assets legally available therefor.

Holders of our common stock do not have preemptive, conversion, subscription or exchange rights, and there are no sinking fund or redemption provisions applicable to our common stock. Holders of our common stock are entitled to receive dividends and other distributions when and as declared by the AIR Board out of funds legally available therefor.

All shares of our common stock offered hereby will, when issued, be fully paid and non-assessable.

Preferred Stock

Our articles of incorporation give the AIR Board the power to issue shares of preferred stock in one or more series without stockholder approval. The AIR Board has the discretion to determine the rights, preferences, privileges and restrictions, including voting rights, dividend rights, conversion rights, redemption privileges and liquidation preferences, of each series of preferred stock. The issuance of preferred stock, while providing desirable flexibility in connection with possible acquisitions and other corporate purposes, could have the effect of making it more difficult for a third party to acquire, or could discourage a third party from acquiring, a majority of a corporation’s outstanding voting stock.

Our articles of incorporation provide that the AIR Board may, by resolution, designate classes or series of preferred stock in the future. Each designated class or series of preferred stock shall have such powers, designations, preferences and relative, participation or optional or other special rights and qualifications, limitations or restrictions as shall be expressed in the resolution adopted by the AIR Board and the related certificate of designation for such

156

Table of Contents

class or series. Prior to the issuance of shares of each class or series of preferred stock, the AIR Board is required by NRS Chapter 78 and our articles of incorporation to adopt resolutions and file a certificate of designation with the Nevada Secretary of State.

Although the AIR Board has no intention at the present time of doing so, it could authorize the issuance of a series of preferred stock that could, depending on the terms of such series, impede the completion of a merger, tender offer or other takeover attempt.

Any future issuance of preferred stock may have the effect of delaying, deferring or preventing a change in control of us without further action by the stockholders and may adversely affect the voting and/or other rights of the holders of common stock or any other securities we may issue in the future. The issuance of shares of preferred stock, or the issuance of rights to purchase such shares, could be used to discourage an unsolicited acquisition proposal. For instance, the issuance of a series of preferred stock might impede a business combination by including class voting rights that would enable the holders to block such a transaction or facilitate a business combination by including voting rights that would provide a required percentage vote of the stockholders. In addition, under certain circumstances, the issuance of preferred stock could adversely affect the voting power of the holders of the common stock. Although the AIR Board is required to make any determination to issue such stock based on its judgment and in accordance with its fiduciary duties under the NRS, the AIR Board could act in a manner that could have the effect of discouraging an acquisition attempt or other transaction that some, or a majority, of the stockholders might believe to be in their best interests or in which stockholders might receive a premium for their stock over the then market price of such stock. The AIR Board does not at present intend to seek stockholder approval prior to any issuance of authorized preferred stock, unless otherwise required by law.

Anti-Takeover Effects of the NRS and AIR’s Articles of Incorporation and Bylaws

Our articles of incorporation, our bylaws and the NRS contain provisions that could delay or make more difficult an acquisition of control of our company not approved by the AIR Board, whether by means of a tender offer, open market purchases, proxy contests or otherwise. These provisions have been implemented to enable us to develop our business in a manner that will foster our long-term growth without disruption caused by the threat of a takeover not deemed by the AIR Board to be in the best interest of the Company. These provisions could have the effect of discouraging third parties from making proposals involving an acquisition or change of control of the Company even if such a proposal, if made, might be considered desirable by a majority of our stockholders. These provisions may also have the effect of making it more difficult for third parties to cause the replacement of our current management without the concurrence of the AIR Board.

Set forth below is a description of the provisions contained in our articles of incorporation, bylaws and the NRS that could impede or delay an acquisition of control of the Company that the AIR Board has not approved. This description is intended as a summary only and is qualified in its entirety by reference to the NRS and our articles of incorporation and bylaws.

Authorized But Unissued Preferred Stock

We are currently authorized to issue a total of 3,000,000 shares of preferred stock. Our articles of incorporation provide that the AIR Board may designate and issue preferred stock without any action of the stockholders. In the event of a hostile takeover, the AIR Board could potentially use this preferred stock to defend the Company’s interests in a threat or proposal involving an acquisition or change of control of the Company even if such a proposal, if made, might be considered desirable by a majority of our stockholders.

Filling Vacancies

The NRS and our articles of incorporation establish that any vacancies on the AIR Board shall be filled solely by the affirmative vote of a majority of the remaining directors then in office, even though less than a quorum of the board

Removal of Directors

The provisions of the NRS and our bylaws may make it difficult for our stockholders to remove one or more of our directors. Our bylaws provide that any director may be removed from office, with or without cause, at any time by the affirmative vote of stockholders holding of record in the aggregate at least two-thirds of the outstanding

157

Table of Contents

shares of stock of AIR. NRS 78.335 provides that any director or one or more of the incumbent directors may be removed as a director only by the vote of stockholders representing not less than two-thirds of the voting power of the issued and outstanding stock entitled to vote.

No Cumulative Voting

The NRS permits cumulative voting in director elections, but only if so provided in a corporation’s articles of incorporation. Our articles of incorporation do not provide the right to cumulate votes in the election of directors. This provision means that the holders of a plurality of the shares voting for the election of directors collectively can elect all of the directors, which could have the effect of making it more difficult for minority stockholders to elect a person to the AIR Board.

Amendments to Articles of Incorporation and Bylaws

The NRS and our articles of incorporation and bylaws give both the AIR Board and the stockholders the power to adopt, amend or repeal the bylaws of the corporation. The stockholders may adopt, alter, amend, change or repeal the bylaws if the proposal thereof is considered by the stockholders at an annual stockholders meeting or a special meeting called, wholly or in part, for such purpose, and the votes cast by the stockholders for the proposal exceeds the votes cast against the proposal. Any bylaw, including any bylaw that has been adopted by the stockholders, may be amended or repealed by the AIR Board unless otherwise prohibited by a bylaw adopted by the stockholders. Except for certain changes in connection with stock splits and a plan of merger, any proposal to amend, alter, change or repeal any provision of our articles of incorporation requires approval by a majority of the voting power of all of the classes of our capital stock entitled to vote on such amendment or repeal, voting together as a single class, and, if the proposed amendment would adversely alter or change any preference or any relative or other right of any class or series of outstanding shares, then also by the holders of shares representing a majority of the voting power of each class adversely affected.

Notwithstanding the foregoing, any determination to pay cash dividends or other distributions subsequent to the merger will be at the discretion of the combined company’s then-current board of directors and will depend upon a number of factors, including the combined company’s results of operations, financial condition, future prospects, contractual restrictions, restrictions imposed by applicable law and other factors that the combined company’s then-current board of directors deems relevant.

COMPARISON OF RIGHTS OF AIR STOCKHOLDERS AND TENAX MEMBERS

The rights of the AIR stockholders are governed by the NRS, AIR’s articles of incorporation and AIR’s bylaws, and the rights of the Tenax Members are governed by the DLLCA, the Tenax certificate of formation and the Tenax LLCA. Pursuant to the merger agreement, assuming the authorized shares proposal and written consent proposal are approved by the AIR stockholders, AIR’s articles of incorporation will be amended to increase the amount of authorized shares of AIR common stock and to permit stockholder action by written consent in lieu of a stockholder meeting where certain conditions are satisfied, as set forth in the form of amendment to AIR’s articles of incorporation in Exhibit E to Annex A to this proxy statement/prospectus, and AIR’s bylaws will be amended to delete the current prohibition of such stockholder actions by written consent. In addition, at the effective time, the certificate of formation of the surviving company will be the certificate of formation of Tenax as of immediately prior to the effective time, and the limited liability company agreement in the form set forth in Exhibit D to Annex A to this proxy statement/prospectus will be the limited liability company agreement of Tenax. As a result of the merger, the Tenax Members will receive shares of AIR common stock as merger consideration and will become stockholders of AIR and, accordingly, their rights will be governed by the NRS, AIR’s articles of incorporation and AIR’s bylaws.

The following chart is a summary of certain material differences as of the date of this proxy statement/prospectus between the rights of the AIR stockholders and the rights of the Tenax Members and does not purport to be a complete description of all of such differences. These differences arise from differences between the respective governing corporate documents and states of incorporation and formation of AIR and Tenax, respectively. This summary is qualified in its entirety by reference to the NRS, the DLLCA and the respective governing documents of AIR and Tenax.

Authorized Stock/Membership Units

AIR is authorized to issue:

 

Tenax is authorized to issue:

20,000,000 shares of common stock, par value $0.001 per share. Upon approval of the authorized shares proposal, AIR will be authorized to issue 200,000,000 shares of common stock, par value $0.001 per share, which would be reduced to 40,000,000 shares of common stock, par value $0.001 per share, after giving effect to such amendment and the reverse stock split; and

 

An unlimited number of Tenax units, divided into Tenax units designated as Class A-1 units (“Class A-1 units”), Tenax units designated as Class A-2 units (“Class A-2 units”) and Tenax units designated as Class A-3 units (“Class A-3 units”).

3,000,000 shares of preferred stock, par value $0.001 per share. The number of authorized shares of preferred stock will not be changed pursuant to the amendment to AIR’s articles of incorporation contemplated by the authorized shares proposal, or by the reverse stock split.

   

Preferred Stock/Additional Membership Units

The AIR articles of incorporation authorize the AIR Board to designate and issue, out of AIR’s authorized and unissued shares of preferred stock, one or more classes or series of preferred stock without approval of the stockholders, by action of the AIR Board and the filing of a certificate of designation filed with the Nevada Secretary of State pursuant to NRS 78.1955, prescribing the voting powers, if any, designations, powers, preferences, and the relative, participating, optional, or other rights, if any, and the qualifications, limitations, or restrictions thereof. The AIR Board may fix the number of shares constituting such class or series, and it may increase or decrease the number of shares of any such class or series, but not below the number of shares thereof then outstanding.

 

Tenax may issue additional Tenax units (including creating additional classes or series thereof having such powers, designations, preferences and rights as may be determined by the Tenax Board) as the Tenax Board may reasonably determine, in each case, subject to compliance with the provisions of the Tenax LLCA.

Quorum

At each meeting of stockholders, except where otherwise provided by law or AIR’s articles of incorporation or AIR’s bylaws, the holders of thirty three and one-third percent in voting power of the outstanding shares of stock entitled to vote on a matter at the meeting, present in person or represented by proxy, constitutes a quorum. Shares entitled to vote as a separate class or series may take action on a matter at a meeting only if a quorum of those shares is present. In the absence of a quorum of the holders of any class or series of stock entitled to vote on a matter, the holders of such class or series so present or represented may, by majority vote, adjourn the meeting of such class or series with respect to that matter from time to time until a quorum of such class or series is present or represented.

At all meetings of the AIR Board, a majority of the directors then in office constitutes a quorum for the transaction of business at such meeting. Where a quorum of the AIR Board is not present, a majority of the directors present may, without notice other than announcement at the meeting, adjourn the meeting from time to time until a quorum can be obtained.

 

Tenax does not have a quorum requirement for the Tenax Members.

With respect to each item of business properly presented to the Tenax Board at any meeting of the Tenax Board, the presence, in person or by proxy, of managers having not less than the minimum number of votes required to approve such item constitutes a quorum. Actions taken by the Tenax Board at board meetings require the approval of a majority of the entire Tenax Board (excluding any vacancy then existing).

Stockholder/Member Voting

Each holder of AIR common stock entitled to vote at any meeting of stockholders is entitled to one vote for each share of AIR common stock held by such stockholder which has voting power upon the matter in question. The holders of common stock vote together as a single class.

 

Tenax Members holding the Class A-1 units or Class A-2 units vote together as a single class on all matters on which they are specifically entitled to vote pursuant to the Tenax LLCA. Each Tenax Member holding Class A-1 units or Class A-2 units is entitled to one vote for each such Class A-1 unit or Class A-2 unit held by such Tenax Member.

Except where applicable law, the rules or regulations of a listing body, AIR’s articles of incorporation or AIR’s bylaws require a different vote, if a quorum exists, action on a matter other than the election of directors is approved if the votes cast favoring the action exceed the votes cast opposing the action. For purposes of AIR’s bylaws, “votes cast” means all votes cast in favor of and against a particular proposal or matter, but not abstentions or broker non-votes.

 

Unless otherwise expressly provided in the Tenax LLCA, actions requiring approval by the Tenax Members require the approval of Tenax Members holding a majority of the outstanding Class A-1 units and Class A-2 units voting together as a single class.

Special Meetings

Special meetings of stockholders may be called by the Chairman of the AIR Board, the President of AIR (if he is also a member of the AIR Board) or the AIR Board. The President or the Secretary of AIR must call a special meeting upon the written demand (which states the purpose or purposes therefor) signed and dated by the holders of shares representing not less than ten percent of all votes entitled to be cast on any issue(s) that may be properly proposed to be considered at the special meeting. Business transacted at any special meeting of stockholders is limited to the purpose or purposes stated in the notice of such meeting.

 

Tenax does not provide for a stockholder-style special meeting mechanism. The Chairman of the Tenax Board or the Tenax Board may at any time call a meeting of the Tenax Board.

Stockholder/Member Action by Written Consent Without a Meeting

AIR’s bylaws currently prohibit stockholder action by written consent in lieu of a stockholder meeting. However, as a condition to the merger and pending approval of the written consent proposal, AIR’s articles of incorporation will be amended to authorize stockholder action by written consent in lieu of a stockholder meeting at any time while NTC Group, Thomas Foley and Taran Bakker and their respective affiliates collectively beneficially own at least a majority of the voting power of the outstanding shares of AIR common stock, and the AIR Board will amend AIR’s bylaws, effective at the closing, to delete Section 1.11 in AIR’s bylaws which prohibits such stockholder actions by written consent.

 

Any action permitted or required to be taken by the Tenax Members may be taken without a meeting, without prior notice and without a vote if a consent or consents in writing, setting forth the action so taken, is signed by Tenax Members holding not less than the minimum approval of the Tenax Members that would be necessary to take such action in accordance with the terms of the Tenax LLCA. Written notice of any such action by written consent must be provided to all Tenax Members within five business days after such action.

Notice of Stockholder/Member Meetings

Whenever stockholders are required or permitted to take any action at a meeting, a notice of the meeting stating the place, if any, date and hour of the meeting, and the means of remote communications, if any, by which stockholders and proxy holders may be deemed to be present in person and vote at such meeting and, in the case of a special meeting, the purpose or purposes for which the meeting is called, must be given to each stockholder entitled to vote at such meeting. Unless otherwise provided by law, AIR’s articles of incorporation or AIR’s bylaws, the notice of any meeting must be given not less than ten nor more than sixty days before the date of the meeting to each stockholder entitled to vote at such meeting. Notice may be given by any means permitted by law. If mailed, such notice is deemed to be given when deposited in the United States mail, postage prepaid, directed to the stockholder at such stockholder’s address as it appears on the records of AIR.

 

Tenax must provide written notice to all Tenax Members at least five business days in advance of any meeting at which a vote will be held.

Advance Notice Requirement for Stockholder/Member Nominations and Proposals

Nominations of persons for election to the AIR Board and the proposal of business to be considered by the stockholders may be made at an annual meeting of stockholders (i) by or at the direction of the Chairman of the AIR Board or the AIR Board pursuant to a resolution adopted by a majority of the whole AIR Board or (ii) by any AIR stockholder that is entitled to vote at the meeting with respect to the election of directors or the business to be proposed by such stockholder, as the case may be, who complies with the advance notice procedures in AIR’s bylaws and that is a stockholder of record at the time such notice is delivered to the Secretary of AIR. Business brought before an annual meeting by a stockholder must be a proper subject for stockholder action under applicable law. To be timely, a stockholder’s notice must be delivered to the Secretary of AIR at the principal executive offices of AIR not less than 75 days nor more than 90 days prior to the first anniversary of the preceding year’s annual meeting; provided, however, that in the event that the date of the annual meeting is advanced by

 

The Tenax LLCA does not provide for an advance notice procedure for Tenax Members acting solely in their capacity as a Tenax Member to nominate persons or bring business before a meeting.

In addition, if the number of directors to be elected is increased and no public announcement naming all nominees or specifying the size of the increased AIR Board is made by AIR at least 80 days prior to the first anniversary of the preceding year’s annual meeting, a stockholder’s notice with respect to nominees for any new positions created by such increase will be considered timely if delivered to the Secretary of AIR at the principal executive offices of AIR not later than the close of business on the tenth day following the day on which such public announcement is first made by AIR.

A stockholder’s notice must set forth (A) as to each person whom the stockholder proposes to nominate for election or reelection as a director all information relating to such person that is required to be disclosed in solicitations of proxies for election of directors, or is otherwise required, in each case pursuant to Regulation 14A under the Exchange Act, including such person’s written consent to being named in the proxy statement as a nominee and to serving as a director if elected; (B) as to any other business that the stockholder proposes to bring before the meeting, a brief description of the business desired to be brought before the meeting, the reasons for conducting such business at the meeting and any material interest in such business of such stockholder and the beneficial owner, if any, on whose behalf the proposal is made; and (C) as to the stockholder giving the notice and a beneficial owner on whose behalf the nomination or proposal is made (i) the name and address of such stockholder, as they appear on AIR’s books, and of such beneficial owner and (ii) the class and number of shares of AIR which are owned beneficially and of record by such stockholder and such beneficial owner.

Nominations of persons for election to the AIR Board may be made at a special meeting of stockholders at which directors are to be elected (i) by or at the direction of the Chairman of the AIR Board or the AIR Board pursuant to a resolution adopted by a majority of the whole AIR Board or (ii) by any AIR stockholder that is entitled to vote at the meeting with respect to the election of directors who complies with the advance notice procedures described above and that is a stockholder of record at the time such notice is delivered to the Secretary of AIR. To be timely, such stockholder’s notice must be delivered to the Secretary of AIR at the principal executive offices of AIR not earlier than the ninetieth day prior to the special meeting and not later than the close of business on the later of the sixtieth day prior to such

Amendment of Articles of Incorporation/Certificate of Formation

Pursuant to NRS 78.390, except as otherwise provided in NRS 78.390(8), 77.340, 78.209 or NRS Chapter 92A, every amendment to the articles of incorporation must be made and approved in the following manner: (a) the board of directors must adopt a resolution setting forth the amendment proposed and submit the proposed amendment to the stockholders for approval and if the corporation is (1) a publicly traded corporation and the amendment proposed relates solely to an increase or decrease in the number of shares the corporation is authorized to issue, the stockholders of the affected class or series, regardless of limitations or restrictions on the voting power of the affected class or series, must approve the proposed amendment; or (2) not a publicly traded corporation, or is a publicly traded corporation but the amendment proposed does not relate solely to an increase or decrease in the number of shares the corporation is authorized to issue, the stockholders holding shares in the corporation representing at least a majority of the voting power, or such greater proportion of the voting power as may be required in the case of a vote by classes or series, as provided in NRS 78.390(2) and 78.390(4), or as may be required by the provisions of the articles of incorporation, must approve the proposed amendment. NRS 78.390(8) permits a corporation to amend its articles of incorporation to change its name without stockholder approval. Except as otherwise provided in NRS 78.390, if any proposed amendment would adversely alter or change any preference or any relative or other right given to any class or series of outstanding shares, then, in addition to any approval otherwise required, the amendment must be approved by the holders of shares representing a majority of the voting power of each class or series adversely affected by the amendment regardless of limitations or restrictions on the voting power thereof. The amendment does not have to be approved by the holders of shares of any class or series whose preference or rights are adversely affected by the amendment if the articles of incorporation specifically deny the holders of such class or series the right to vote on such an amendment. Provision may be made in the articles of incorporation requiring, in the case of any specified amendments, approval by a larger proportion of the voting power of stockholders than that required by NRS 78.390.

 

Amendments to the Tenax certificate of formation may be made at any time in accordance with the DLLCA. Such amendments require approval of the Tenax Board and, where required under the Tenax LLCA, the consent of NEH.

AIR’s articles of incorporation provide that AIR reserves the right to amend, alter, change, or repeal all or any portion of the provisions contained in AIR’s articles of incorporation from time to time in accordance with the laws of the state of Nevada, and all rights conferred on stockholders in AIR’s articles of incorporation are granted subject to this reservation.

   

Bylaws/LLCA Amendments

Pursuant to NRS 78.120(2), unless otherwise prohibited by any bylaw adopted by the stockholders, the directors may adopt, amend or repeal any bylaw, including any bylaw adopted by the stockholders.

Under AIR’s articles of incorporation, the AIR Board has the power to adopt, amend or repeal, from time to time, AIR’s bylaws. The AIR stockholders entitled to vote may also adopt additional bylaws and may amend or repeal any bylaw, whether or not adopted by them, at an annual stockholders meeting or a special meeting. The power of the AIR Board to adopt, amend or repeal AIR’s bylaws may be limited by an amendment to AIR’s articles of incorporation or an amendment to AIR’s bylaws adopted by the AIR stockholders entitled to vote that provides that a particular bylaw or bylaws may only be adopted, amended or repealed by the AIR stockholders entitled to vote.

 

Except as otherwise provided in the Tenax LLCA, the Tenax LLCA may be amended, or its provisions waived, with the approval of the Tenax Board and the written consent of NEH, subject to certain protective provisions requiring the consent of any Tenax Member or Tenax Warrantholder where any amendment or waiver would increase such holder’s obligation to make capital contributions or obligations with respect to other liabilities. The consent of certain Tenax Members or Tenax Warrantholders is also required where any amendment or waiver would materially and adversely affect their rights or obligations.

Number and Term of Directors/Managers

The AIR Board must consist of not less than one member, the number thereof to be determined from time to time by resolution of the AIR Board.

 

The Tenax Board is comprised of one or more managers. NEH may at any time increase or decrease the number of managers.

Directors are elected at each annual meeting of stockholders and hold office until the next annual meeting of stockholders, and until the director’s successor is elected and qualified or until the director’s prior death, resignation, removal or disqualification.

 

A manager holds office until his or her successor is appointed or until his or her earlier death, resignation or removal.

Election of Directors/Managers

Directors are elected by a plurality of the votes of the shares present in person or represented by proxy at a meeting and entitled to vote for directors.

 

Managers are appointed by NEH from time to time.

Removal of Directors/Managers

The AIR bylaws provide that any director may be removed from office, with or without cause, at any time by the affirmative vote of stockholders holding of record in the aggregate at least two-thirds of the outstanding shares of stock of AIR. NRS 78.335 provides that any director or one or more of the incumbent directors may be removed as a director only by the vote of stockholders representing not less than two-thirds of the voting power of the issued and outstanding stock entitled to vote.

 

Any manager may be removed at any time with or without cause by NEH.

Filling Vacancies on the Board

Newly created directorships resulting from any increase in the number of directors, or any vacancies on the AIR Board resulting from death, resignation, removal or other causes, shall be filled only by the affirmative vote of a majority of the remaining directors then in office, even if the remaining directors constitute less than a quorum. Such elected directors hold office for the remainder of the full term of the class of directors in which the new directorship was created or the vacancy occurred and until such director’s successor is elected and qualified or until such director’s death, resignation or removal, whichever first occurs.

 

At any time a vacancy is created on the Tenax Board by reason of the incapacity, death, removal or resignation of any manager, NEH has the right, but not the obligation, to appoint an individual to fill the vacancy.

Dividends and Distributions

Subject to the provisions of NRS 78.288, dividends and other distributions may be declared by the AIR Board in such form, frequency and amounts as the condition of the affairs of AIR renders advisable.

 

Subject to applicable law and the maintenance by Tenax of appropriate reserves (as determined by the Tenax Board), Tenax will make distributions to the Tenax Members of cash and other property (other than tax distributions made pursuant to the Tenax LLCA) when and as determined by the Tenax Board, pro rata in accordance with the respective number of Class A-1 units, Class A-2 units (if outstanding) and Class A-3 units held by each such holder. In addition, the Tenax Board must cause Tenax to distribute to each Tenax Member, with respect to each quarterly estimated tax period, an amount of cash based on each Tenax Member’s estimated allocable taxable income and respective tax rate.

Transfer Rights and Restrictions

Subject to any transfer restrictions set forth or referred to on the stock certificate or of which AIR otherwise has notice, shares of AIR are transferable on the books of AIR upon presentation to AIR or to AIR’s transfer agent of a stock certificate signed by, or accompanied by an executed assignment form, from the holder of record thereof, his duly authorized legal representative, or other appropriate person as permitted by NRS Chapter 78 or other applicable law. AIR may require that any transfer of shares be accompanied by proper evidence reasonably satisfactory to AIR or to AIR’s transfer agent that such endorsement is genuine and effective. Upon presentation of shares for transfer, the payment of all taxes, if any, therefor, and the satisfaction of any other requirement of law, including inquiry into and discharge of any adverse claims of which AIR has notice, AIR must issue a new certificate to the person entitled thereto and cancel the old certificate. Every transfer of stock must be entered on the stock books of AIR to accurately reflect the record ownership of each share. The AIR Board may make such additional rules and regulations as it may deem expedient concerning the issue, transfer, and registration of certificates for shares of the capital stock of AIR. NRS 78.242 also imposes certain approval and notice requirements regarding the imposition of transfer restrictions upon shares of stock outstanding at the time of imposition of the restriction.

 

The Tenax units are subject to transfer restrictions. Except for limited permitted transfers, including certain intra-group transfers, no Tenax Member may transfer Tenax units without the prior written consent of the Tenax Board in its sole discretion. Any transfer must comply with applicable securities laws and certain treasury regulations, and the transferee must execute a joinder agreement. Certain transfers are subject to tag-along and drag-along rights.

Registration Rights

There are no registration rights provisions in AIR’s articles of incorporation or AIR’s bylaws.

 

Upon the completion of an initial public offering of the common equity of Tenax, or any successor-in-interest to Tenax, pursuant to an effective registration statement filed with the SEC in accordance with the Securities Act, or at such time prior thereto as the Tenax Board may determine in connection with a company restructuring, Tenax and the Tenax Members will enter into a customary registration rights agreement providing for demand and piggyback registration rights.

Put/Call Rights

There are no put/call rights provisions in AIR’s articles of incorporation or AIR’s bylaws.

 

Following the sixth anniversary of the Tenax LLCA, warrant securityholders may elect to require Tenax to repurchase all of such holder’s warrants and warrant units at fair market value, and Tenax may require any warrant securityholder to sell all of its warrants and warrant units to Tenax at fair market value. If any payment restriction prohibits such repurchases or sales, the closing for such repurchases or sales may be extended in accordance with the Tenax LLCA. These repurchase rights of the warrant securityholders and Tenax terminate upon the occurrence of certain qualifying public listings.

Company Restructuring

There is no comparable provision in AIR’s articles of incorporation or AIR’s bylaws.

 

The Tenax Board may effect a company restructuring (including a merger with or into a publicly traded entity or subsidiary thereof) in anticipation of or in connection with certain initial public offerings, company sale events or other strategic transactions. No company restructuring that would materially and adversely affect the rights, preferences or privileges of any Tenax Member (other than NEH) in a manner disproportionate to NEH may be effected without the prior written consent of the holders of a majority on a fully diluted, as-exercised, as-converted basis of the Tenax units held by Tenax Members other than NEH. Tenax must provide each Tenax Member with at least 20 business days’ prior written notice of any proposed company restructuring, together with reasonable detail regarding its terms and effects. To the extent applicable in any company restructuring, all Tenax units will be converted or exchanged into equity of the surviving company at the same rate and relative economic value, and the governing documents of the surviving entity will contain provisions, including economic rights, preferences and privileges (including minority protections) as nearly as practicable in all material respects the same as set forth in the Tenax LLCA. All Tenax Members must take such actions as may be reasonably required and otherwise cooperate in good faith with Tenax, in each case at Tenax’s expense, in connection with consummating a company restructuring including voting for or consenting thereto.

Rights of Dissent and Appraisal

Under NRS 92A.300 to 92A.500, inclusive, stockholders of a Nevada corporation may, subject to certain conditions, limitations and exceptions, be entitled to dissent from a transaction and demand payment of the fair value of such stockholder’s shares in the event of certain corporate actions, including certain mergers.

No rights of dissent are available to the stockholders of AIR in connection with the merger.

 

Under Section 18-210 of the DLLCA, unless otherwise provided in a limited liability company agreement or an agreement of merger or consolidation or a plan of merger or a plan of division, no appraisal rights are available with respect to a limited liability company interest or another interest in a limited liability company.

Under the Tenax LLCA, no Tenax Member will have any dissenters’, appraisal or other similar rights in connection with any company restructuring that complies with the Tenax LLCA, except to the extent such rights are provided by applicable law or as expressly set forth in the Tenax LLCA.

Preemptive Rights

There are no preemptive rights provisions in AIR’s articles of incorporation or AIR’s bylaws.

 

In the event of certain proposed issuances by Tenax, which issuance has been approved in accordance with the requirements of the Tenax LLCA, Tenax must deliver to each holder a written notice setting forth the total amount and class of equity interests to be issued by Tenax, the proposed price thereof, and other material terms thereof. During the period of 20 business days following delivery of such notice, each holder has the right to deliver to Tenax a written notice electing to purchase, at the proposed price thereof, the amount of equity interests not exceeding the total amount of equity interests proposed to be issued. Each electing holder is entitled to purchase the lesser of (a) the amount it elected to purchase and (b) its pro rata share of the total amount of equity interests proposed to be issued, subject to adjustment if the aggregate amount of equity interests to be issued exceeds the amount of equity interests elected to be purchased by the electing holder. Any equity interests proposed to be issued by Tenax that are not purchased by the electing holders may be sold by Tenax to any person at a price not lower than the proposed price, provided that such sale occurs no later than 90 days following the date of the original notice.

Exclusive Forum Provision

There is no exclusive forum provision in AIR’s articles of incorporation or AIR’s bylaws.

 

Any legal action or proceeding arising out of the Tenax LLCA must be brought only in the state or federal courts located in the State of Delaware.

Limitation of Liability on Directors/Managers and Officers

Unless otherwise provided by law, a director or officer is not individually liable to AIR or its stockholders or creditors for any damages as a result of any act or failure to act in his individual capacity as a director or officer unless it is proven that his act or failure to act constituted a breach of his fiduciary duties as a director or officer and his breach of those duties involved intentional misconduct, fraud, or a knowing violation of law. If the NRS is amended to further eliminate or limit or authorize corporate action to further eliminate or limit the liability of directors or officers, the liability of directors and

 

None of the Tenax Members or managers have any personal liability for the debts, obligations or liabilities of Tenax except to the extent provided in the DLLCA or the Tenax LLCA.

None of the Tenax Members or managers are liable to Tenax or any other Tenax Member or manager for any loss, liability, damage or claim incurred by reason of any act or omission performed or omitted by such Tenax Member or manager in good faith on behalf of Tenax, except for any act taken by a Tenax Member or manager purporting to bind Tenax that has not been authorized

officers of the corporation will be eliminated or limited to the fullest extent permitted by the NRS as so amended from time to time. Neither any amendment nor repeal of Article 9 of AIR’s articles of incorporation, nor the adoption of any provision of AIR’s articles of incorporation inconsistent with Article 9 of AIR’s articles of incorporation, will eliminate, reduce or otherwise adversely affect any limitation on the personal liability of a director or officer of the corporation existing at the time of such amendment, repeal or adoption of such an inconsistent provision.

 

pursuant to the Tenax LLCA or any taken by a Tenax Member that constitutes a breach of the Tenax LLCA. A Tenax Member or manager is fully protected in relying in good faith upon the records of Tenax and upon such information, opinions, reports or statements presented to Tenax by any person or entity as to matters which such Tenax Member or manager reasonably believes are within such person’s or entity’s professional or expert competence.

The Tenax LLCA is not intended to, and does not, create or impose any fiduciary duty on any Tenax Member or manager. Furthermore, each of the Tenax Members, the managers and Tenax waives any and all fiduciary duties (and all such fiduciary duties are hereby eliminated) that, absent such waiver, may be implied or imposed by applicable law, and in doing so, acknowledges and agrees that the duties and obligation of each Tenax Member and manager to each other and to Tenax are only as expressly set forth in the Tenax LLCA. The provisions of the Tenax LLCA, to the extent that they restrict or eliminate the duties and liabilities of a Tenax Member or a manager otherwise existing at law or in equity, are agreed by the Tenax Members and managers to replace such other duties and liabilities of such Tenax Members and managers, as applicable.

Indemnification of Directors/Managers and Officers and Advancement of Expenses

The AIR articles of incorporation provide that every person who was or is a party to, or is threatened to be made a party to, or is involved in any action, suit or proceeding, whether civil, criminal, administrative or investigative, by the reason of the fact that he or she, or a person with whom he or she is a legal representative, is or was a director or officer of AIR, or who is serving at the request of AIR as a director or officer of another corporation, or is a representative in a partnership, joint venture, trust or other enterprise, must be indemnified and held harmless to the fullest extent legally permissible under the laws of the State of Nevada from time to time against all expenses, liability and loss (including attorneys’ fees, judgments, fines, and amounts paid or to be paid in a settlement) reasonably incurred or suffered by him or her in connection therewith. Such right of indemnification is a contract right which may be enforced in any manner desired by such person. The AIR articles of incorporation also provide that the expenses of officers and directors incurred in defending a civil suit or proceeding must be paid by AIR as incurred and in advance of the final disposition of the action, suit, or proceeding, under receipt of an undertaking by or on behalf of the director or officer to repay the amount if it is ultimately determined by a court of competent jurisdiction that he or she is not entitled to be indemnified by AIR. Such right of indemnification is not exclusive of any other right of such directors, officers or representatives may have or acquire, and, without limiting the generality of such statement, they are entitled to their respective rights of indemnification under any bylaw agreement, vote of stockholders, provision of law, or otherwise, as well as their rights under Article 10 of AIR’s articles of incorporation.

 

To the fullest extent permitted by law, Tenax must indemnify an indemnified representative, which includes any and all Tenax Members (and any and all officers, directors and employees thereof), managers and officers of Tenax or any Tenax subsidiary, Tenax Warrantholders designated as an observer and any other person so designated by the Tenax Board, against any liability incurred in connection with any proceeding in which such representative may be involved as a party or otherwise by reason of the fact that such person is or was serving in an indemnified capacity (as defined in the Tenax LLCA), including liabilities resulting from any actual or alleged breach or neglect of duty, error, misstatement or misleading statement or act giving rise to strict products liability; provided, however, that any indemnity under the Tenax LLCA must be provided out of and to the extent of Tenax’s assets only, and no Tenax Member has any personal liability on account thereof; provided further that no indemnity is payable under the Tenax LLCA (i) against any liability incurred by such indemnified representative by reason of any action or omission that constitutes fraud, willful misconduct or gross negligence or for which a corporation, incorporated under the General Corporations Law of the State of Delaware, would not be permitted under applicable law to indemnify or (ii) in connection with any proceeding between the Tenax Members or Tenax Warrantholders or any claim for breach by a Tenax Member or Tenax Warrantholder of the Tenax LLCA or other related agreements.

Tenax

Without limiting the application of the foregoing, the AIR Board may adopt bylaws from time to time with respect to indemnification, to provide at all times the fullest indemnification permitted by the laws of the State of Nevada, and may cause the corporation to purchase or maintain insurance on behalf of any person who is or was a director or officer of the corporation or who is serving at the request of the corporation as an officer, director or representative of any other entity or other enterprise against any liability asserted against such person and incurred in any such capacity or arising out of such status, whether or not the corporation would have the power to indemnify such person.

Any repeal or modification of the applicable provisions of Article 10 of AIR’s articles of incorporation, approved by the AIR stockholders, is prospective only, and does not adversely affect any limitation on the liability of a director or officer of the corporation existing as of the time of such repeal or modification.

 

To the fullest extent permitted by law, Tenax may pay the expenses (including attorneys’ fees and disbursements) incurred in good faith by an indemnified representative in advance of the final disposition of a proceeding upon receipt of an undertaking by or on behalf of the indemnified representative to repay the amount if it is ultimately determined that such person is not entitled to be indemnified by Tenax pursuant to Article IX of the Tenax LLCA.

In addition, Tenax may maintain insurance, obtain a letter of credit, act as self-insurer, create a reserve, trust, escrow, cash collateral or other fund or account, enter into indemnification agreements, pledge or grant a security interest in any assets or properties of Tenax, or use any other mechanism or arrangement whatsoever in such amounts, at such costs, and upon such other terms and conditions as the Tenax Board deems appropriate.

The rights granted by Article IX of the Tenax LLCA are not deemed exclusive of any other rights to which those seeking indemnification, contribution or advancement of expenses may be entitled under any statute, agreement, vote of the Tenax Members or disinterested Tenax Members or otherwise, both as to action in an indemnified capacity and as to action in any other capacity. The indemnification, contribution and advancement of expenses provided by or granted pursuant to Article IX of the Tenax LLCA continue as to a person who has ceased to be an indemnified representative in respect of matters arising prior to such time, and inure to the benefit of the successors, heirs, executors, administrators and personal representatives of such a person.

PRINCIPAL STOCKHOLDERS OF COMBINED COMPANY

The following information does not give effect to the reverse stock split.

The following table sets forth, as of June 30, 2026, certain information with respect to the shares of AIR common stock beneficially owned by (i) stockholders expected by AIR and Tenax to own more than 5% of the outstanding shares of common stock of the combined company, (ii) each person expected to be a director or named executive officer of the combined company and (iii) all of the combined company’s expected executive officers and directors as a group.

The percentage of shares beneficially owned listed in the table below is based on 125,307,820 shares of AIR common stock expected to be outstanding upon the closing of the merger. Neither AIR nor Tenax know of any arrangements, including any pledge by any person of securities of the combined company, the operation of which may at a subsequent date result in a change in control of the combined company.

Beneficial ownership is determined in accordance with the rules of the SEC and generally includes any shares over which a person exercises sole or shared voting or investment power. Except as indicated by the footnotes below, AIR and Tenax believe, based on the information furnished to them, that the persons named in the table below will have sole voting and investment power with respect to all shares of AIR common stock shown that they beneficially own as of the closing, subject to community property laws where applicable. The information does not necessarily indicate beneficial ownership for any other purpose, including for purposes of Section 13(d) and 13(g) of the Securities Act.

Immediately after the closing of the merger, holders of AIR common stock as of immediately prior to the effective time are expected to collectively own approximately 4% of the outstanding shares of the common stock of the combined company, on a fully diluted basis, and the Tenax Members and Tenax Warrantholders as of immediately prior to the effective time are expected to collectively own approximately 96% of the outstanding shares of the common stock of the combined company, on a fully diluted basis. The following table and the related notes assume that, at the effective time, (i) the outstanding Tenax units will convert into the right to receive approximately 120,457,162 shares of AIR common stock, subject to adjustment as provided in the merger agreement including in connection with the reverse stock split, and (ii) no Tenax Warrantholders exercise their warrants to purchase Tenax units prior to the closing of the merger. For more information, see the section entitled “The Merger Agreement — Adjustments to the Merger Consideration” beginning on page 38 of this proxy statement/prospectus.

Unless otherwise noted below, the address of each beneficial owner listed in the table below is Tenax Aerospace Acquisition, LLC, 400 West Parkway Place, Suite 201, Ridgeland, Mississippi 39157.

LEGAL MATTERS

Ellenoff Grossman & Schole LLP will pass on the validity of the AIR common stock offered by this proxy statement/prospectus.

EXPERTS

The consolidated financial statements of AIR and its subsidiaries as of and for the year ended December 31, 2025, have been audited by CBIZ CPAs P.C., an independent registered public accounting firm, as stated in their report which includes an explanatory paragraph as to the Company’s ability to continue as a going concern. We have included our financial statements in this proxy statement/prospectus in reliance upon the report pertaining to such financial statements of such firm given on their authority as experts in accounting and auditing.

The consolidated financial statements of AIR and its subsidiaries as of and for the year ended December 31, 2024, have been audited by Marcum LLP, an independent registered public accounting firm, as stated in their report which includes an explanatory paragraph as to the Company’s ability to continue as a going concern. We have included our financial statements in this proxy statement/prospectus in reliance upon the report pertaining to such financial statements of such firm given on their authority as experts in accounting and auditing.

The consolidated financial statements of Tenax and its subsidiaries as of December 31, 2025 and 2024, and for each of the years in the three-year period ended December 31, 2025, have been audited by KPMG LLP, independent auditors, as stated in their report appearing herein. Such consolidated financial statements are included in reliance upon the report of such firm given their authority as experts in accounting and auditing.

INDEPENDENT AUDITORS

With respect to Tenax’s unaudited interim financial information for the periods ended March 31, 2026 and 2025, included herein, the independent auditor for Tenax, KPMG LLP, has reported that they applied limited procedures in accordance with professional standards for a review of such information. However, their separate report for Tenax’s quarter ended March 31, 2026, and included herein, states that they did not audit and they do not express an opinion on that interim financial information. Accordingly, the degree of reliance on their report on such information should be restricted in light of the limited nature of the review procedures applied. The accountants are not subject to the liability provisions of Section 11 of the Securities Act for their report on the unaudited interim financial information because that report is not a “report” or a “part” of the registration statement prepared or certified by the accountants within the meaning of Sections 7 and 11 of the Securities Act.

AIR INDUSTRIES GROUP

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

Note 1. ORGANIZATION AND BASIS OF PRESENTATION

Organization

Air Industries Group is a Nevada corporation (“AIRI”). The accompanying condensed consolidated financial statements presented are those of AIRI, and its wholly-owned subsidiaries: Air Industries Machining Corp. (“AIM”), Nassau Tool Works, Inc. (“NTW”), and the Sterling Engineering Corporation (“Sterling”) (together, the “Company”).

Basis of Presentation

The accompanying unaudited condensed consolidated financial statements of the Company have been prepared in accordance with U.S. generally accepted accounting principles for interim financial information and with Rule 8-03 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by generally accepted accounting principles for complete financial statements. In the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation have been included. Operating results for the three months ended March 31, 2026 are not necessarily indicative of the results that may be expected for the year ending December 31, 2026. These unaudited condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2025, as filed with the Securities and Exchange Commission on March 27, 2026, from which the accompanying condensed consolidated balance sheet dated December 31, 2025 was derived.

Going Concern and Management’s Plan

As of March 31, 2026, the Company was in default of its minimum Fixed Charge Coverage Ratio (“FCCR”), of 1.10x as of the last day of the Fiscal Quarter, having only attained a ratio of 0.93x. All other financial and business covenants required under the terms of the Current Credit Facility were met. The Company’s debt under our Current Credit Facility and Related Party Subordinated Notes approximates $29,747,000. The Current Credit Facility is scheduled to expire on September 30, 2026, and the Related Party Subordinated Notes mature on October 1, 2026. These obligations are classified as current liabilities on the consolidated balance sheets as of March 31, 2026. As a result of the default, the expiration dates of our Current Credit Facility and the rights that our Current Credit Facility lender could exercise, there is substantial doubt about the Company’s ability to continue as a going concern for the twelve months following the date of filing of these condensed consolidated financial statements. The terms of all outstanding indebtedness are discussed further in “Note 5. Debt”.

The Company is required to maintain a collection account with its lender into which substantially all cash receipts are remitted. Additionally, as the Company is in default of its Current Credit Facility, the lender could choose to exercise its rights, for example, increasing the rate of interest or refusing to make loans under the revolving portion of the Current Credit Facility and keep the funds remitted to the collection account. If the lender were to raise the rate of interest or exercise other remedies available under the Current Credit Facility, it would adversely impact the Company’s operating results. If the lender were to cease making new loans under the revolving facility or limit availability under the revolving facility, the Company would lack the funds to continue operations or, possibly, expand its operations.

The Company is actively engaged in constructive discussions with various lenders as the Company has been advised by its lender that it will not renew its Current Credit Facility. While these discussions have been professional and remain ongoing, there can be no assurance that agreements will be reached with existing lenders or alternative financing sources.

To support current operations and strategic initiatives, the Company has raised capital through public market sales of its common stock since December 2024 and believes it can continue to access equity markets in future periods. During the year ended December 31, 2025, the Company generated gross proceeds of $4,869,000 through an At The Market (“ATM”) Offering, of which approximately $3,930,000 is restricted for the benefit of the Current Credit Facility lender. In light of the entry into the Merger Agreement with Tenax (each as defined in “Note 11. Merger Information”), the Company has temporarily paused all equity raising activity. See “Note 11. Merger Information”.

AIR INDUSTRIES GROUP

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

Note 1. ORGANIZATION AND BASIS OF PRESENTATION (cont.)

As of March 31, 2026, the Company had total unfilled contract values amounting to $269.2 million (including its $134.7 million in funded backlog plus additional potential funded orders against Long-Term Agreements (“LTAs”). These unfilled contract values support a positive outlook for future growth; however extended lead times for raw material procurement and the complexity of manufacturing processes are expected to delay revenue acceleration until late 2026.

The Company generally sources its raw material, principally metal casting or forgings, from domestic sources. As such, the Company is generally not exposed to increased prices on imports but would be subject to increased prices if proposed tariffs or disruptions in supply chains resulting from tariffs or other geopolitical events cause the general level of prices for its products to increase. One component used by the Company on a key commercial aviation program is sourced from China. The Company’s contract with its customer for the product requires the Company to absorb the first five percent (5%) of any cost increases with further increases absorbed by the customer.

A substantial portion of the Company’s products are used in United States military aviation and as such, changes in the US defense budget are more material to demand than to changes in general economic conditions. However, the Company does have significant exposure in commercial aviation; demand for these products may be reduced if general economic conditions deteriorate reducing demand for commercial air travel.

The accompanying consolidated financial statements do not include any adjustments relating to the recoverability and classification of recorded assets or the classification of liabilities that might be necessary should the Company be unable to continue as a going concern.

Note 2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Accounts Receivable

Accounts receivable are carried at the original invoice amount less an estimate made for expected credit losses based on a review of all outstanding amounts on a quarterly basis. Management determines the allowance for expected credit losses primarily using historical experience as well as current conditions that affect the collectability of the reported amount. Accounts receivable are written off when deemed uncollectible. Bad debt expenses are recorded in operating expenses on the consolidated statements of operations.

The activity for the allowance for credit losses during the three months ended March 31, 2026 and 2025 is set forth in the table below:

Inventory Valuation

The Company values inventory at the lower of cost or estimated net realizable value using the first-in first out method. The Company periodically evaluates inventory items not secured by backlog and establishes write-downs to estimated net realizable value for excess quantities, slow-moving goods, obsolescence and for other impairments of value. Adjustments to inventory net realizable value are recorded in cost of sales.

Note 2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (cont.)

As of March 31, 2026, and December 31, 2025 the Company reported restricted cash of $3,930,000 on its condensed consolidated balance sheets. Restricted cash represents proceeds from the Company’s ATM offering that are pledged as security for its obligations under the Current Credit Facility.

Major Suppliers

The Company utilizes sole-source suppliers to supply raw materials or other parts used in production. These suppliers are its only source for such parts and, therefore, in the event any of them were to go out of business or be unable or unwilling to provide parts for any reason, the Company’s business would be severely harmed.

Customer Deposits

The Company receives advance payments on certain contracts with the remainder of the contract balance due upon the shipment of the final product once the customer inspects and approves the product for shipment. At that time, the entire amount will be recognized as revenue and the deposit will be applied to the customer’s invoice.

At March 31, 2026 and December 31, 2025, customer deposits were $968,000 and $391,000, respectively. The Company recognized revenue of $100,000 during the three months ended March 31, 2026 that was included in customer deposits balance as of December 31, 2025. The Company recognized revenue of $531,000 during the three months ended March 31, 2025, that was included in the customer deposits balance as of December 31, 2024.

Backlog

Backlog represents the value of orders received pursuant to our Long-Term Agreements (“LTA”) or spot orders pursuant to a purchase order. As of March 31, 2026, backlog relating to remaining performance obligations on contracts was approximately $134.7 million. The Company estimates that a substantial portion of this backlog will be recognized as net sales during the next twenty-four months, with the rest thereafter. This expectation assumes that raw material supplies and outsourced processing is completed and delivered on time and that the Company’s customers will accept delivery as scheduled. The Company anticipates that sales during the aforementioned periods will also include sales from expected new orders that are not included in our backlog.

Earnings (Loss) per share

Basic earnings (loss) per share (“EPS”) is computed by dividing the net income (loss) applicable to common stockholders by the weighted-average number of shares of common stock outstanding for the period.

For purposes of calculating diluted earnings (loss) per common share, the numerator includes net income (loss) plus interest on convertible notes payable assumed converted as of the first day of the period. The denominator includes both the weighted-average number of shares of common stock outstanding during the period and the number of common stock equivalents if the inclusion of such common stock equivalents is dilutive. Dilutive common stock equivalents potentially include stock options and warrants using the treasury stock method and convertible notes payable using the if-converted method.

Stock-Based Compensation

The Company accounts for stock-based compensation in accordance with FASB ASC 718, “Compensation — Stock Compensation.” Under the fair value recognition provision of the ASC, stock-based compensation cost is estimated at the grant date based on the fair value of the award. The Company estimates the fair value of stock options and warrants granted using the Black-Scholes-Merton option pricing model and stock grants at their closing reported market value. Stock-based compensation expense for employees amounted to $535,000 and $435,000 for the three months ended March 31, 2026 and 2025, respectively. Stock-based compensation expense for directors amounted to $429,000 and $39,000 for the three months ended March 31, 2026 and 2025, respectively. Stock compensation expenses for employees and directors were included in operating expenses in the accompanying condensed consolidated statements of operations.

Recently Issued Accounting Pronouncements

In November 2024, the FASB issued ASU 2024-03, “Disaggregation of Income Statement Expenses”, which requires public business entities to disclose additional information about specific expenses categories in the notes to financial statements at interim and annual reporting periods. The amendments in ASU 2024-03 are effective for annual reporting periods beginning after December 15, 2026, and interim reporting periods beginning after December 15, 2027. Early adoption is permitted. The Company is currently assessing the impact that adoption of this new accounting guidance will have on its consolidated financial statements and footnote disclosures.

The Company does not believe that any other recently issued, but not yet effective, accounting standards if currently adopted would have a material effect on the accompanying condensed consolidated financial statements.

Note 5. DEBT (cont.)

Current Credit Facility

The Company has a credit facility (“Current Credit Facility”) with Webster Bank that expires on September 30, 2026. This facility, which was entered into on December 31, 2019, was amended several times and now provides for a $20,000,000 revolving loan (“Revolving Line of Credit”), a $5,700,000 term loan and a $1,640,000 term loan (“Term Loans”). The loan is secured by a lien on substantially all of the assets of the Company.

As of March 31, 2026, there is $19,283,000 outstanding under the Revolving Line of Credit and $5,593,000 under the Term Loans.

As discussed in Note 1, the Company was in default of its minimum Fixed Charge Coverage Ratio (“FCCR”) of 1.10x as of March 31, 2026, and the Current Credit Facility expires on September 30, 2026. Therefore, the entire Term Loan and all amounts due under the Revolving Line of Credit are classified as short term as of March 31, 2026.

The below table shows the timing of payments due under the Term Loan:

Interest expense related to the Current Credit Facility amounted to approximately $379,000 and $315,000 for the three months ended March 31, 2026 and 2025, respectively. Interest expense includes the amortization of deferred finance costs of $0 and $17,000 for the three months ending March 31, 2026 and 2025, respectively.

The below summarizes various terms of the Current Credit Facility:

        The Company is required to meet a Fixed Charge Coverage Ratio (as defined) that is determined at the end of each fiscal quarter of 1.10x. As of March 31,2026, the Company was in default with this ratio having attained a ratio of only 0.93. At December 31, 2025, the Company was in full compliance with its covenants.

The Current Credit Facility limits the amount of capital expenditures and dividends the Company can pay to its stockholders. As of March 31, 2026, the Company was in compliance with this Covenant.

Substantially all of the Company’s assets are pledged as collateral.

        For so long as the Term Loan remains outstanding, if Excess Cash Flow (as defined) is a positive number for any fiscal year the Company shall pay an amount equal to the lesser of (i) twenty-five percent (25%) of the Excess Cash Flow for such fiscal year and (ii) the outstanding principal balance of the term loan. Such payment shall be applied to the outstanding principal balance of the Term Loan, on or prior to the April 15 immediately following such fiscal year. For the fiscal year ended December 31, 2025, based on the calculation there was no Excess Cash Flow payment required.

        Both the Revolving Line of Credit and the Term Loan will bear an interest rate equal to the greater of (i) 3.50% and (ii) a rate per annum equal to the rate per annum published from time to time in the “Money Rates” table of the Wall Street Journal (or such other presentation within The Wall Street Journal as may be adopted hereafter for such information) as the base or prime rate for corporate loans at the nation’s largest commercial bank, less sixty-five hundredths (-0.65%) of one percent per annum.

Note 5. DEBT (cont.)

The below summarizes certain amendments to the Current Credit Facility

        On January 30, 2025, we entered into an Eighth Amendment to provide for an additional Term Loan in the amount of $1,640,000 for the acquisition of additional equipment. The monthly principal installments on this additional Term Loan are $19,524. This amendment further revised our Financial Covenants. For the rolling twelve-month period ending March 31, 2025 and June 30, 2025, we are required to achieve a Fixed Charge Coverage Ratio of 1.05x. Beginning with the rolling twelve-month period ending September 30, 2025 and going forward the Company is required to achieve a Fixed Charge Coverage Ratio of 1.25x. Additionally, the Company is allowed to pay off up to $4,800,000 of related party notes with funds raised in the Company’s At The Market debt offering. All other covenants remain unchanged. In connection with these changes, the Company paid an amendment fee of $20,000.

        On September 10, 2025, the Company entered into a Ninth Amendment where it agreed that $3,930,000 of the proceeds from its ATM Offering would be maintained in an interest bearing account. The funds in this account serve as additional security for its obligations under the Current Credit Facility. Additionally, this amendment waived the default as June 30, 2025.

        On December 15, 2025, the Company entered into a Tenth Amendment which waived the defaults caused by the failure to achieve the required fixed charge coverage ratio for the fiscal quarter ended June 30, 2025, and for exceeding the permitted amount of capital expenditures for the fiscal year ending December 31, 2025. Additionally, the maturity date of the revolving credit and term loans were extended to March 31, 2026, and the capital expenditure covenant was amended. The company paid an amendment fee of $40,000.

        On February 26, 2026, the Company entered into an Eleventh Amendment to which extended the maturity date of the revolving credit and term loans to September 30, 2026. The company paid an amendment fee of $25,000 and agreed to pay an additional fee of $150,000 on the maturity date.

As the Company is in default under the Current Credit Facility, the lender could exercise additional rights and remedies, such as increasing the rate of interest on outstanding amounts or refuse to make loans under the revolving portion of the Current Credit Facility and keep the funds remitted to the collection account. If the lender were to cease making new loans under the revolving facility or limit the amount of loans under the revolving facility, the Company would lack the funds to continue or, possibly, expand operations. To date, the lender has chosen not to exercise any of its remedies, though we agreed to put $3,930,000 of ATM proceeds in an interest bearing account to serve as additional security for the Company’s obligations under the Current Credit Facility. The Company is actively engaged in constructive discussions with various lenders as the Company has been advised by its lender that it will not renew its Current Credit Facility. While these discussions have been professional and remain ongoing, there can be no assurance that agreements will be reached with existing lenders or with alternative financing sources.

All amendment fees paid in connection with the Current Credit Facility that are for a future benefit of the Company are included in Deferred Financing Costs, Net, Deposits and Other Assets, in the accompanying consolidated balance sheets and are amortized over the term of the loan.

As of March 31, 2026, the Company has borrowing capacity of approximately $717,000 under the Revolving Loan.

Solar Credit Facility

On August 16, 2023, the Company entered into a financing agreement (“Solar Credit Facility”) with CT Green Bank, a quasi-public agency of the State of Connecticut, for the installation of solar energy systems including replacing the existing roof (“Project”) at its Sterling facility. Advances were made by CT Green Bank upon its approval of costs incurred on the Project up to $934,000. As of October 1, 2024, cumulative advances totaling $934,000 had been made including the payment of CT Green Bank’s closing costs of $25,000. Total interest accrued on the advances at the rate of 5% was $36,000.

Note 8. COMMITMENTS AND CONTINGENCIES

On October 2, 2018, Contract Pharmacal Corp. (“Contract Pharmacal”) commenced an action, relating to a Sublease entered into between the Company and Contract Pharmacal in May 2018 with respect to the property that was formerly occupied by the Company’s former subsidiary WMI, at 110 Plant Avenue, Hauppauge, New York. In the action, Contract Pharmacal sought damages for an amount in excess of $1,000,000 for the Company’s alleged violation of the terms of the subject sublease, specifically the failure to make the entire premises available by what it claims was the Sublease commencement date. The validity of the action is extremely suspect in that the subject sublease had no specific commencement date and Contract Pharmacal ultimately received all the space. Discovery was conducted and the Plaintiff moved for summary judgement and to amend its complaint to add a new cause of action all of which the company opposed. On July 8, 2021, the Court denied Contract Pharmacal’s motion for summary judgement and to add an additional cause of action. In the Order, the Court granted Contract Pharmacal’s Motions to drop its claim for specific performance and to amend its Complaint to reduce its claim for damages to $700,000 both of which benefit the Company. Following the Court’s decision, Contract Pharmacal filed a Motion to reargue its original motion which the Company opposed. The Court denied that motion on November 30, 2021 and then on March 10, 2022, Contract Pharmacal filed an appeal of the Court’s decision with the Appellate Division of the State of New York. The Company opposed that action. The Company was again successful as the Appellate Division upheld the lower court’s denial of Contract Pharmacal’s motion for summary judgement and its motion to amend its Complaint. Contract Pharmacal has now submitted a motion to the Appellate Division requesting leave to reargue the court’s denial of its original appeal. The Company will oppose that motion. The Appellate Division has yet to act in respect to Contract Pharmacal’s most recent motion to reargue the Court’s denial of the original appeal. The Company continues to dispute the validity of the claims asserted by Contract Pharmacal and intends to contest them vigorously.

From time to time the Company may be engaged in various lawsuits and legal proceedings in the ordinary course of business. The Company is currently not aware of any legal proceedings the ultimate outcome of which, in its judgment based on information currently available, would have a material adverse effect on its business, financial condition or operating results. In consultation with legal counsel, there are no proceedings in which any of the Company’s directors, officers or affiliates, or any registered or beneficial stockholder of its common stock, is an adverse party or has a material interest adverse to our interest.

Note 9. INCOME TAXES

The Company recorded no income tax expense for the three months ended March 31, 2026 and 2025 because the estimated annual effective tax rate was zero. In determining the estimated annual effective income tax rate, the Company analyzes various factors, including projections of the Company’s annual earnings and taxing jurisdictions in which the earnings will be generated, the impact of state and local income taxes, the ability to use tax credits and net operating loss carry forwards, and available tax planning alternatives.

As of March 31, 2026, and December 31, 2025, the Company provided a full valuation allowance against its net deferred tax assets since the Company believes it is more likely than not that its deferred tax assets will not be realized.

Note 10. SEGMENT INFORMATION

The Company operates as one operating segment. The Company’s Chief Operating Decision Maker (“CODM”) is its Chief Executive Officer, who reviews financial information presented on a consolidated basis. The CODM used consolidated sales, gross margin and net income (loss) to assess financial performance and allocate resources. These financial metrics are used by the CODM to make key operating decisions, such as the need to allocate its budget to operating expenses and invest in additional equipment. The segment assets are equal to the assets presented in the condensed consolidated balance sheets.

The significant expenses that are regularly provided to the CODM are disclosed in the consolidated statements of operations as a part of the condensed consolidated net income (loss). See the condensed consolidated financial statements for all financial information regarding the Company’s operating segment.

All revenues of the Company are earned in the United States of America.

The Company’s long-lived tangible assets, as well as the Company’s operating lease right-of use assets recognized on the Condensed Consolidated Balance Sheets were located in the United States.

Note 11. MERGER INFORMATION

On February 16, 2026, the Company and Transitory Air Sub LLC, its wholly owned subsidiary (“Merger Sub”), entered into an Agreement and Plan of Merger (the “Merger Agreement”) with Tenax Aerospace Acquisition, LLC, a Delaware limited liability company (“Tenax”). Upon consummation of the merger contemplated by the Merger Agreement (the “Merger”), Tenax will become a wholly owned subsidiary of the Company.

Pursuant to the Merger Agreement, the Company will issue shares of its common stock (the “Merger Consideration”) to the holders of the membership interests of Tenax (the “Tenax Members”) at the closing of the Merger. A portion of the Merger Consideration allocated in respect of membership interests of Tenax underlying certain Tenax warrants that remain unexercised as of the closing, if any, will be reserved by the Company for future issuance upon the exercise of such warrants. The number of shares of the Company’s common stock to be issued to the Tenax Members will be adjusted based on a calculation of AIR Net Indebtedness (as defined in the Merger Agreement). Based on the amount of AIR Net Indebtedness as of March 31, 2026, the calculation would result in the issuance of approximately 122.6 million shares of the Company’s common stock. Consequently, based upon the calculation of the Merger Consideration as of March 31, 2026, following the closing of the Merger, the Tenax Members will collectively own approximately 96% of the outstanding shares of the Company’s common stock.

The closing of the Merger is subject to risks and uncertainties and certain specified conditions, including, among other things: (a) the expiration or termination of the applicable waiting period under the Hart-Scott-Rodino Act, (b) the listing of the Merger Consideration on the NYSE American, and (c) other customary conditions for a transaction such as the Merger, such as the absence of any legal restraint prohibiting the consummation of the Merger and there not having occurred with respect to the Company or Tenax’s business a material adverse event, subject to certain customary exceptions.

Tenax is a leading provider of special mission aviation solutions that combine aircraft sourcing, financing and modification with aviation services including pilots, maintenance and other types of program support. Additionally, Tenax has a long-standing relationship with key government customers.

Air Industries Group

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheet of Air Industries Group and subsidiaries (the “Company”) as of December 31, 2025, the related consolidated statements of operations, changes in stockholders’ equity and cash flows for the year ended December 31, 2025, and the related notes (collectively referred to as the “financial statements”). In our opinion, the financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2025, and the results of its operations and its cash flows for the year ended December 31, 2025, in conformity with accounting principles generally accepted in the United States of America.

Explanatory Paragraph — Going Concern

The accompanying consolidated financial statements have been prepared assuming that the Company will continue as a going concern. As more fully described in Note 1, the Current Credit Facility is scheduled to expire on September 30, 2026 and the Related Party Subordinated Notes mature on October 1, 2026. In addition, the Company is required to maintain a collection account with its lender into which substantially all the Company’s cash receipts are remitted. If the Company’s lender were to cease lending and keep the funds remitted to the collection account, the Company would lack the funds to continue its operations. The Current Credit Facility and Related Party Subordinated notes expiration dates and the rights granted to the lender raise substantial doubt about its ability to continue as a going concern. Management’s plans in regard to these matters are also described in Note 1. The consolidated financial statements do not include any adjustments that might result from the outcome of this uncertainty.

Basis for Opinion

These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on the Company’s financial statements based on our audit. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (“PCAOB”) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audit we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Company’s internal control over financial reporting. Accordingly, we express no such opinion.

Our audit included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audit also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audit provides a reasonable basis for our opinion.

The accompanying financial statements have been prepared assuming that the Company will continue as a going concern. As more fully described in Note 1, the Current Credit Facility expires on December 30, 2025. In addition, the Company is required to maintain a collection account with its lender into which substantially all the Company’s cash receipts are remitted. If the Company’s lender were to cease lending and keep the funds remitted to the collection account, the Company would lack the funds to continue its operations. The current credit facility expiration date and the rights granted to the lender, combined with the reasonable possibility that the Company might fail to meet covenants in the future, raise substantial doubt about its ability to continue as a going concern. Management’s plans in regard to these matters are also described in Note 1. The financial statements do not include any adjustments that might result from the outcome of this uncertainty.

Basis for Opinion

These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on the Company’s financial statements based on our audit. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (“PCAOB”) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audit, we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Company’s internal control over financial reporting. Accordingly, we express no such opinion.

Our audit included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audit also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audit provides a reasonable basis for our opinion.

AIR INDUSTRIES GROUP
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Note 1. ORGANIZATION AND BASIS OF PRESENTATION

Organization

Air Industries Group is a Nevada corporation (“AIRI”). As of and for the years ended December 31, 2025 and 2024, the accompanying consolidated financial statements presented are those of AIRI, and its wholly-owned subsidiaries; Air Industries Machining Corp. (“AIM”), Nassau Tool Works, Inc. (“NTW”), and the Sterling Engineering Corporation (“Sterling”), (together, the “Company”).

Principal Business Activity

The Company is a leading manufacturer of precision assemblies and components for large aerospace and defense prime contractors. Its products include landing gears, flight controls, engine mounts and components for aircraft jet engines, ground turbines and other complex machines. Most of its machined components and assemblies are integral to high-profile platforms and named programs including the F-18 Hornet, the E2D Hawkeye, the UH-60 Black Hawk Helicopter, the Geared Turbo-Fan Engine, the CH-53 Helicopter, the F-35 Lighting II (also known as the Joint Strike Fighter) and the F-15 Eagle Tactical Fighter.

The Company’s direct customers are primarily large aerospace and defense prime contractors. The ultimate end-users for most of its products are the U.S. Government, international governments, and commercial global airlines.

Basis of Presentation

The accompanying consolidated financial statements of the Company have been prepared in accordance with generally accepted accounting principles (“GAAP”) in the United States of America and the rules and regulations of the Securities and Exchange Commission. All dollar amounts have been rounded to the nearest whole number. As a result, totals may not sum precisely due to rounding.

Going Concern and Management’s Plan

As of December 31, 2025, debt under the Company’s Current Credit Facility and Related Party Subordinated Notes approximates $28,344,000. The Current Credit Facility is scheduled to expire on September 30, 2026, and the Related Party Subordinated Notes mature on October 1, 2026. These obligations are classified as current liabilities on the consolidated balance sheets as of December 31, 2025. As a result of the aforementioned and rights that the Current Credit Facility lender could exercise, there is substantial doubt about the Company’s ability to continue as a going concern for the twelve months following the date of filing of these consolidated financial statements.

The Company is actively engaged in constructive discussions with various lenders as the Company has been advised by its lender that it will not renew its Current Credit Facility. While these discussions have been professional and remain ongoing, there can be no assurance that agreements will be reached with existing lenders or through alternative financing sources.

To support current operations and strategic initiatives, the Company has raised capital through public market sales of its common stock since December 2024 and believes it can continue to access equity markets in future periods. During the year ended December 31, 2025, the Company generated gross proceeds of $4,869,000 through an At The Market (“ATM”) Offering, of which approximately $3,930,000 is restricted for the benefit of the Current Credit Facility lender. In light of ongoing negotiations with all of our lenders and the terms of the Merger Agreement with Tenax, the Company has temporarily paused all equity raising activity.

As of December 31, 2025, the Company was in compliance with its minimum Fixed Coverage Charge ratio (“FCCR”) of 1.10x on a quarterly basis as well as the requirement that fixed asset acquisitions not exceed $3,300,000. All other financial and business covenants under the terms its Current Credit Facility were met as of December 31, 2025. The terms of all outstanding indebtedness are discussed further in “Note 8. Debt”.

F-28

Table of Contents

AIR INDUSTRIES GROUP
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Note 1. ORGANIZATION AND BASIS OF PRESENTATION (cont.)

The Company is required to maintain a collection account with its lender into which substantially all cash receipts are remitted. Additionally, if the Company were to be in default of its Current Credit Facility the lender could choose to exercise its rights, for example, increasing the rate of interest or refusing to make loans under the revolving portion of the Current Credit Facility and keep the funds remitted to the collection account. If the lender were to raise the rate of interest or exercise other remedies available under the Current Credit Facility, it would adversely impact the Company’s operating results. If the lender were to cease making new loans under the revolving facility or limit availability under the revolving facility, the Company would lack the funds to continue operations or, possibly, expand its operations.

As a result of recent contract awards, as of December 31, 2025, the Company had total unfilled contract values amounting to $270.1 million (including its $136.8 million in funded backlog plus additional potential funded orders against Long-Term Agreements (“LTAs”). These unfilled contract values support a positive outlook for future growth; however, extended lead times for raw material procurement and the complexity of manufacturing processes are expected to delay revenue acceleration until late 2026.

The Company generally sources its raw material, principally metal casting or forgings, from domestic sources. As such, the Company is generally not exposed to increased prices on imports but would be subject to increased prices if proposed tariffs or disruptions in supply chains resulting from tariffs or other geopolitical events, cause the general level of prices for its products to increase. One component used by the Company on a key commercial aviation program is sourced from China. The Company’s contract with its customer for the product requires the Company to absorb the first five percent (5%) of any cost increases with further increases absorbed by the customer.

A substantial portion of the Company’s products are used in United States military aviation and as such, changes in the US defense budget are more material to demand than to changes in general economic conditions. However, the Company does have significant exposure in commercial aviation; demand for these products may be reduced if general economic conditions deteriorate reducing demand for commercial air travel.

The accompanying consolidated financial statements do not include any adjustments relating to the recoverability and classification of recorded assets or the classification of liabilities that might be necessary should the Company be unable to continue as a going concern.

Note 2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Principles of Consolidation

The accompanying consolidated financial statements include accounts of the Company and its wholly-owned subsidiaries. Significant intercompany accounts and transactions have been eliminated in consolidation.

Accounts Receivable

Accounts receivable are carried at the original invoice amount less an estimate made for expected credit losses based on a review of all outstanding amounts on a quarterly basis. Management determines the allowance for expected credit losses primarily using historical experience as well as current conditions that affect the collectability of the reported amount. Accounts receivable are written off when deemed uncollectible. Bad debt expenses are recorded in operating expenses on the consolidated statements of operations.

Inventory Valuation

The Company values inventory at the lower of cost or estimated net realizable value using the first-in first out method. The Company periodically evaluates inventory items not secured by backlog and establishes write-downs to estimated net realizable value for excess quantities, slow-moving goods, obsolescence and for other impairments of value. Adjustments to inventory net realizable value are recorded in cost of sales.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Note 2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (cont.)

Property and Equipment

Property and equipment are carried at cost net of accumulated depreciation and amortization. Repair and maintenance charges are expensed as incurred. Property, equipment, and improvements are depreciated using the straight-line method over the estimated useful lives of the assets or the particular improvements. Expenditures for repairs and improvements in excess of $10,000 that add to the productive capacity or extend the useful life of an asset are capitalized. Upon disposition, the cost and related accumulated depreciation are removed from the accounts and any related gain or loss is reflected in earnings.

Long-Lived Assets

Long-lived assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset to future undiscounted net cash flows expected to be generated by the asset. If such assets are considered to be impaired, the impairment to be recognized is measured by the amount by which the carrying amount of the assets exceeds the fair value of the assets. There were no events triggering a review for impairment during the years ended December 31, 2025 and 2024.

Deferred Financing Costs

Costs incurred with obtaining and executing revolving debt arrangements are capitalized and recorded in other Deferred financing costs, net, deposits, and other assets and amortized using the effective interest method over the term of the related debt. Costs incurred with obtaining and executing other debt arrangements are presented as a direct deduction from the carrying value of the associated debt and also amortized using the effective interest method over the term of the related debt. The amortization of financing costs is included in interest expense in the Consolidated Statements of Operations.

Contract Costs Receivable

Contract costs receivable represent costs to be reimbursed from a terminated contract. Contract costs receivable totals $0 at December 31, 2025 and $296,000 at December 31, 2024. The Company collected this receivable on March 18, 2025.

Risks and Uncertainties

The continuing impacts of rising interest rates, inflation, changes in foreign currency exchange rates and geopolitical developments, such as the ongoing conflict between Russia and Ukraine, the ongoing conflict between Israel and Hamas, and the ongoing conflict between the United States, Israel and Iran, the imposition of tariffs and shifts in international alliances, have resulted, and may continue to result, in a global slowdown of economic activity, which may decrease demand for a broad variety of goods and services, including those provided by the Company’s clients and as a result, the Company, while also disrupting supply channels, sales channels and advertising and marketing activities for an unknown period of time. Additionally, recent changes to U.S. policy implemented by the U.S. Congress, and the Executive Branch and the responses of other nations to such actions have impacted and may in the future impact, among other things, the U.S. and global economy, international alliances and trade relations, unemployment, immigration, healthcare, taxation, the U.S. regulatory environment, inflation and other areas. As a result of the current uncertainty regarding economic activity, the Company is unable to predict the size and duration of the impact on its revenue and its results of operations, if any, of actions taken to date and those that may occur in the future. The extent of the potential impact of these macroeconomic factors on the Company’s operational and financial performance will depend on a variety of factors, including the extent of geopolitical disruption and its impact on the Company’s clients, partners, industry, and employees, all of which are uncertain at this time and cannot be accurately predicted. The Company continues to monitor the effects of these macroeconomic factors and intends to take steps deemed appropriate to limit the impact on its business.

Note 2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (cont.)

There can be no assurance that precautionary measures, whether adopted by the Company or imposed by others, will be effective, and such measures could negatively affect its sales, marketing, and client service efforts, delay and lengthen its sales cycles, decrease its employees’, clients’, or partners’ productivity, or create operational or other challenges, any of which could harm its business and results of operations.

Segment Reporting

Operating segments are identified as components of an enterprise about which separate discrete financial information is available for evaluation by the operating decision makers, or decision-making group, in making decisions on how to allocate resources and assess performance. The Company operates as a single reportable segment, as the Chief Operating Decision Maker (“CODM”) reviews financial performance and makes decisions on a consolidated basis. (See Note 15. Segment Reporting).

Revenue Recognition

The Company recognizes revenue to depict the transfer of promised goods to customers in an amount that reflects the consideration to which the Company expects to be entitled in exchange for those goods.

Revenue is recognized as the customer obtains control of the goods and services promised in the contract (i.e., performance obligations). In evaluating our contracts with our customers, we have determined that there is no future performance obligation once delivery has occurred.

The Company’s revenue is generated from fixed-price contracts. Under fixed-price contracts, the Company agrees to perform the specified work for a pre-determined price, which is estimated during the bidding process before the contract is awarded. To the extent actual costs vary from the estimates upon which the price was negotiated, the Company will generate more or less profit or could incur a loss.

The Company evaluates the products promised in each contract at inception to determine whether the contract should be accounted for as having one or more performance obligations. The Company’s contracts are typically accounted for as one performance obligation. The Company classifies net sales as products on its consolidated statements of operations based on the predominant attributes of the performance obligations.

The Company determines the transaction price for each contract based on the consideration expected to be received for the products being provided under the contract.

At the inception of a contract, the Company estimates the transaction price based on its current rights and does not contemplate future modifications (including unexercised options) or follow-on contracts until they become legally enforceable. Contracts can be subsequently modified to include changes in specifications, requirements or price, which may create new or change existing enforceable rights and obligations. Depending on the nature of the modification, the Company considers whether to account for the modification as an adjustment to the existing contract or as a separate contract. Generally, modifications to contracts are not distinct from the existing contract due to the significant integration and interrelated tasks provided in the context of the contract. Therefore, such modifications are accounted for as if they were part of the existing contract and recognized as a cumulative adjustment to revenue.

The Company recognizes revenue at the point in time in which the performance obligation is fully satisfied. This is satisfied when the product has shipped, which is the point in time the customer obtains control of the product and the Company no longer maintains control of the product.

Payment terms and conditions vary by contract, although terms generally include a requirement of payment within 30 to 75 days.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Note 2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (cont.)

Payments received in advance from customers are recorded as customer deposits until earned, at which time revenue is recognized. The Terms and Conditions contained in customer purchase orders often provide for liquidated damages in the event that a stop work or contract termination order is issued prior to final delivery. While the products manufactured are specific to the type of aircraft that they are used on, there are alternate customers that can acquire and utilize these products.

Warranties are provided on certain contracts, but do not provide for services beyond standard assurances and are therefore not considered to be separate performance obligations. Warranties during the years ended December 31, 2025 and 2024, were not material.

Customer Deposits

The Company receives advance payments on certain contracts with the remainder of the contract balance due upon the shipment of the final product once the customer inspects and approves the product for shipment. At that time, the entire amount will be recognized as revenue and the deposit will be applied to the customer’s invoice.

At December 31, 2025 and 2024, customer deposits were $391,000 and $1,115,000, respectively. The Company recognized revenue of $724,000 during year ended December 31, 2025, that was included in the customer deposits balance as of December 31, 2024. The Company recognized revenue of $2,442,000 during the year ended December 31, 2024, that was included in the customer deposits balance of $3,557,000 as of December 31, 2023.

Backlog

Backlog represents the value of orders received pursuant to Long-Term Agreements (“LTA”) or spot orders pursuant to a customer purchase order. As of December 31, 2025, backlog relating to remaining performance obligations on contracts was approximately $136.8 million. The Company estimates that a substantial portion of this backlog will be recognized as net sales during the next twenty-four months, with the rest thereafter. This expectation assumes that raw material suppliers and outsourced processing is completed and delivered on time and that the Company’s customers will accept delivery as scheduled. The Company anticipates that sales during the aforementioned periods will also include sales from expected new orders that are not in our backlog.

Use of Estimates

In preparing the financial statements, management is required to make estimates and assumptions that affect the reported amounts in the financial statements and accompanying notes. The more significant management estimates are inventory valuation, and income tax provision. Actual results could differ from those estimates. Changes in facts and circumstances may result in revised estimates, which are recorded in the period in which they become known.

Credit and Concentration Risks

A large percentage of the Company’s revenues are derived directly from large aerospace and defense prime contractors for which the ultimate end-user is the U.S. Government, international governments or commercial airlines.

Cash

For the years ended December 31, 2025 and 2024, the Company had occasionally maintained balances in its bank accounts that were in excess of the FDIC limit. The Company has not experienced any losses on these accounts.

As of December 31, 2025, and December 31, 2024 the Company reported restricted cash of $3,930,000 and $0 on its consolidated balance sheets. Restricted cash represents proceeds from the Company’s ATM offering that are pledged as security for its obligations under the Current Credit Facility.

Major Suppliers

The Company utilizes sole-source suppliers to supply raw materials or other parts used in production. These suppliers are its only source for such parts and, therefore, in the event any of them were to go out of business or be unable or unwilling to provide parts for any reason, its business could be severely harmed.

Income Taxes

The Company accounts for income taxes in accordance with accounting guidance now codified as Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) 740, “Income Taxes,” which requires that the Company recognize deferred tax liabilities and assets based on the differences between the financial statement carrying amounts and the tax bases of assets and liabilities, using enacted tax rates in effect in the years the differences are expected to reverse.

F-33

Table of Contents

AIR INDUSTRIES GROUP
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Note 2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (cont.)

The provision for, or benefit from, income taxes includes deferred taxes resulting from the temporary differences in income for financial and tax purposes using the liability method. Such temporary differences result primarily from the differences in the carrying value of assets and liabilities. Future realization of deferred income tax assets requires sufficient taxable income within the carryback, carryforward period available under tax law. We evaluate, on a quarterly basis whether, based on all available evidence, it is probable that the deferred income tax assets are realizable. Valuation allowances are established when it is more likely than not that the tax benefit of the deferred tax asset will not be realized. The evaluation, as prescribed by ASC 740-10, includes the consideration of all available evidence, both positive and negative, regarding historical operating results including recent years with reported losses, the estimated timing of future reversals of existing taxable temporary differences, estimated future taxable income exclusive of reversing temporary differences and carryforwards, and potential tax planning strategies which may be employed to prevent an operating loss or tax credit carryforward from expiring unused.

The Company accounts for uncertainties in income taxes under the provisions of ASC 740 which clarify the accounting for uncertainty in income taxes recognized in an enterprise’s financial statements. The standard prescribes a recognition threshold and measurement attribute for the financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return. The Subtopic provides guidance on the de-recognition, classification, interest and penalties, accounting in interim periods, disclosure and transition.

Earnings (Loss) per share

Basic earnings (loss) per share (“EPS”) is computed by dividing the net loss applicable to common stockholders by the weighted-average number of shares of common stock outstanding for the period.

For purposes of calculating diluted earnings (loss) per common share, the numerator includes net income (loss) plus interest on convertible notes payable assumed converted as of the first day of the period. The denominator includes both the weighted-average number of shares of common stock outstanding during the period and the number of common stock equivalents if the inclusion of such common stock equivalents is dilutive. Dilutive common stock equivalents potentially include stock options and warrants using the treasury stock method and convertible notes payable using the if-converted method.

There were no adjustments to net loss applicable to common shareholders utilized to calculate EPS.

The following securities have been excluded from the calculation as the exercise price was greater than the average market price of the common stock and because the effect of including these potential shares was anti-dilutive due to the net loss incurred during that period:

Stock-Based Compensation

The Company accounts for stock-based compensation in accordance with FASB ASC 718, “Compensation — Stock Compensation.” Under the fair value recognition provision of the ASC, stock-based compensation cost is estimated at the grant date based on the fair value of the award. The Company estimates the fair value of stock options and warrants granted using the Black-Scholes-Merton option pricing model and stock grants at their closing reported market value. Stock compensation expense for employees amounted to $939,000 and $640,000 for the years ended December 31, 2025 and 2024, respectively. Stock compensation expense for directors amounted to $108,000 and $157,000 for the years ended December 31, 2025 and 2024, respectively. Stock compensation expenses for employees and directors were included in operating expenses in the accompanying consolidated statements of operations.

Freight Out

Freight out is included in operating expenses and amounted to $52,000 and $67,000 for the years ended December 31, 2025 and 2024, respectively.

Leases

In accordance with FASB ASC 842, “Leases” (“ASC 842”), the Company records a right-of-use (ROU) asset and a lease liability on the balance sheet for all leases with terms longer than 12 months and classifies them as either operating or finance leases. The lease classification affects the expense recognition in the consolidated statement of operations. Operating lease charges are recorded entirely in operating expenses. Finance lease charges are split, where amortization of the right-of- use asset is recorded in operating expenses and an implied interest component is recorded in interest expense.

At the inception of an arrangement, the Company determines whether the arrangement is or contains a lease based on the unique facts and circumstances present and the classification of the lease including whether the contract involves the use of a distinct identified asset, whether the Company obtains the right to substantially all of the economic benefit from the use of the asset, and whether the Company has the right to direct the use of the asset. Leases with a term greater than one year are recognized on the balance sheet as ROU assets, lease liabilities and, if applicable, long-term lease liabilities. The Company has elected not to recognize on the balance sheet leases with terms of one year or less under the practical expedient. For contracts with lease and non-lease components, the Company has elected not to allocate the contract consideration, and to account for the lease and non-lease components as a single lease component.

Lease liabilities and their corresponding ROU assets are recorded based on the present value of lease payments over the expected lease term. The implicit rates within the Company’s operating leases are generally not determinable and, therefore, the Company uses the incremental borrowing rate at the lease commencement date to determine the present value of lease payments. The determination of the Company’s incremental borrowing rate requires judgment. The Company determines the incremental borrowing rate for each lease using its estimated borrowing rate, adjusted for various factors including level of collateralization, term and currency to align with the terms of the lease. The operating lease ROU asset also includes any lease prepayments, offset by lease incentives.

An option to extend the lease is considered in connection with determining the ROU asset and lease liability when it is reasonably certain the Company will exercise that option. An option to terminate is considered unless it is reasonably certain we will not exercise the option.

Assets held under finance lease obligations are depreciated over the shorter of their related lease terms or their estimated useful lives.

Recently Issued Accounting Pronouncements

In December 2023, the FASB issued ASU 2023-09 “Income Taxes (Topic 740): Improvements to Income Tax Disclosures”, related to improvements to income tax disclosures. The amendments in this update require enhanced jurisdictional and other disaggregated disclosures for the effective tax rate reconciliation and income taxes paid. The amendments in this update are effective for fiscal years beginning after December 15, 2024. The Company adopted the guidance prospectively in the fiscal year beginning January 1, 2025 and additional required disclosures have been included in Note13.

In November 2024, the FASB issued ASU 2024-03, “Disaggregation of Income Statement Expenses”, which requires public business entities to disclose additional information about specific expense categories in the notes to financial statements at interim and annual reporting periods. The amendments in ASU 2024-03 are effective for annual reporting periods beginning after December 15, 2026, and interim reporting periods beginning after December 15, 2027. Early adoption is permitted. The Company is currently assessing the impact that adoption of this new accounting guidance will have on its consolidated financial statements and footnote disclosures.

The Company does not believe that any other recently issued, but not yet effective, accounting standards if currently adopted would have a material effect on the accompanying consolidated financial statements.

Note 7. SALE-LEASEBACK TRANSACTION

On October 24, 2006, the Company consummated a Sale — Leaseback Arrangement, whereby the Company sold the buildings and real property located in Bay Shore, New York (the “Bay Shore Property”) for a purchase price of $6,200,000. The Company realized a gain on the sale of $1,051,000 of which $300,000 was recognized during the year ended December 31, 2006. The remaining $751,000 is being recognized ratably over the remaining term of the twenty — year lease at approximately $38,000 per year. The gain is included in Other Income in the accompanying Consolidated Statements of Operations. The unrecognized portion of the gain in the amount of $28,000 and $67,000 as of December 31, 2025 and 2024, respectively, is classified as Deferred Gain on Sale in the accompanying Consolidated Balance Sheets.

The Company accounted for these transactions under the provisions of FASB ASC 840-40, “Leases-Sale-Leaseback Transactions.”

Simultaneous with the closing of the sale of the Bay Shore Property, the Company entered into a 20-year lease (the “Lease”) expiring in September 2026 with the purchaser for the property. Base annual rent is approximately $540,000 for the first five years, $560,000 for the sixth year, and thereafter increases 3% per year. The Lease grants the Company an option to renew the Lease for an additional period of five years. The Company has on deposit with the landlord $89,000 as security for the performance of its obligations under the Lease. Pursuant to the terms of the Lease, the Company is required to pay all of the costs associated with the operation of the facilities, including, without limitation, insurance, taxes and maintenance. The lease also contains customary representations, warranties, obligations, conditions and indemnification provisions and grants the landlord customary remedies upon a breach of the lease by the Company, including the right to terminate the Lease and hold the Company liable for any deficiency in future rent.

Current Credit Facility

The Company has a credit facility (“Current Credit Facility”) with Webster Bank that expires on September 30, 2026. This facility, which was entered into on December 31, 2019, was amended several times, and now provides for a $20,000,000 revolving loan (“Revolving Line of Credit”), and a $5,700,000 term loan (“Term Loan”). An additional advance under the Term Loan was made during the first quarter of 2025 in the amount of $1,640,000 and reference herein to the “Term Loan” for periods after the date of such advance include the $1,640,000. The loan is secured by a lien on substantially all of the assets of the Company.

As of December 31, 2025, there is $17,618,000 outstanding under the Revolving Line of Credit and $5,855,000 under the Term Loan.

As discussed in Note 1, the Current Credit Facility expires on September 30, 2026. Therefore, amounts owed under the agreement are classified as short term as of December 31, 2025.

Interest expense related to the Current Credit Facility amounted to approximately $1,361,000 and $1,304,000 for the years ended December 31, 2025 and 2024, respectively. Interest expense includes the amortization of deferred finance costs of $69,000 and $68,000 in 2025 and 2024, respectively.

The below summarizes various terms of the Current Credit Facility:

        The Company was required to meet a Fixed Charge Coverage Ratio (as defined) that is determined at the end of each fiscal quarter on a rolling twelve month basis of 1.05x and beginning with the fiscal quarter ending September 30, 2025, the Company is required to meet a Fixed Coverage Charge Ratio of 1.25x. The Company achieved the required FCCR for the period ended September 30, 2025, but did not meet the required FCCR for the period ended June 30, 2025, having attained a ratio of only 0.76x. Pursuant to the 10th Amendment to the current credit facility (detailed below), the Company was required to and achieved the required Fixed Coverage Charge Ratio of 1.10x for the three months ending December 31, 2025. At both December 31, 2025 and 2024, the Company was in full compliance with its covenants.

The Current Credit Facility limits the amount of capital expenditures and dividends the Company can pay to its stockholders. As of December 31, 2025, the Company was in compliance with this Covenant.

Substantially all of the Company’s assets are pledged as collateral.

        For so long as the Term Loan remains outstanding, if Excess Cash Flow (as defined) is a positive number for any fiscal year the Company shall pay an amount equal to the lesser of (i) twenty-five percent (25%) of the Excess Cash Flow for such fiscal year and (ii) the outstanding principal balance of the term loan. Such payment shall be applied to the outstanding principal balance of the Term Loan, on or prior to the April 15 immediately following such fiscal year. For the fiscal year ended December 31, 2025, based on the calculation there is no Excess Cash Flow payment required.

        Both the Revolving Line of Credit and the Term Loan will bear an interest rate equal to the greater of (i) 3.50% and (ii) a rate per annum equal to the rate per annum published from time to time in the “Money Rates” table of the Wall Street Journal (or such other presentation within The Wall Street Journal as may be adopted hereafter for such information) as the base or prime rate for corporate loans

at the nation’s largest commercial bank, less sixty-five hundredths (-0.65%) of one percent per annum. The average interest rate charged was 6.72% and 7.55% for the years ended December 31, 2025 and 2024, respectively.

The below summarizes historical amendments to the Current Credit Facility

        On May 31, 2024, the Company entered into a Seventh Amendment that waived the default caused by the failure to achieve the required Fixed Charge Coverage Ratio of the Sixth Amendment. This amendment further revised the Financial Covenants. For the six months ending June 30, 2025, EBITDA shall not be less than $740,000; for the nine months ending September 30, 2025, EBITDA shall not be less than $1,500,000; for the twelve months ending December 31, 2025, EBITDA shall not be less than $2,800,000. For the rolling twelve-month period ending March 31, 2025, the Company is required to achieve a Fixed Charge Coverage Ratio of 1.05x. Beginning with the rolling twelve-month period ending June 30, 2025, and going forward the required Fixed Charge Coverage Ratio is 1.25x. All other covenants remain unchanged. Additionally, this amendment increased the Term Loan by approximately $1,000,000 to $5,700,000, with monthly principal installments in the amount of $68,000. In connection with these changes, the Company paid an amendment fee of $20,000.

        On January 30, 2025, the Company entered into an Eighth Amendment to provide for an additional Term Loan in the amount of $1,640,000 for the acquisition of additional equipment. The monthly principal installments on this additional Term Loan are $19,524. This amendment further revised the Financial Covenants. For the rolling twelve-month period ending March 31, 2025 and June 30, 2025, the Company is required to achieve a Fixed Charge Coverage Ratio of 1.05x. Beginning with the rolling twelve-month period ending September 30, 2025 and going forward, the required Fixed Charge Coverage Ratio is 1.25x. Additionally, the Company is allowed to pay off up to $4,800,000 of related party notes with funds raised in the Company’s At The Market debt offering. All other covenants remain unchanged. In connection with these changes, the Company paid an amendment fee of $20,000.

        On September 10, 2025, the Company entered into a Ninth Amendment where it agreed that $3,930,000 of the proceeds from its ATM Offering would be maintained in an interest bearing account. The funds in this account serve as additional security for its obligations under the Current Credit Facility. Additionally, this amendment waived the default as June 30, 2025.

        On December 15, 2025, the Company entered into a Tenth Amendment which waived the defaults caused by the failure to achieve the required fixed charge coverage ratio for the fiscal quarter ended June 30, 2025, and for exceeding the permitted amount of capital expenditures for the fiscal year ending December 31, 2025. Additionally, the maturity date of the revolving credit and term loans were extended to March 31, 2026, and amended the capital expenditure covenant. The Company paid an amendment fee of $40,000.

        On February 26, 2026, the Company entered into an Eleventh Amendment which extended the maturity date of the revolving credit and term loans to September 30, 2026. The Company paid an amendment fee of $25,000.

Currently, at any time, Webster Bank could choose to exercise additional rights, that it has as a result of the Company’s defaults under the Current Credit Facility. For example, it could increase the rate of interest or refuse to make loans under the revolving portion of the Current Credit Facility and keep the funds remitted to the collection account. If the lender were to cease making new loans under the revolving facility or limit the amount of loans under the revolving facility, the Company would lack the funds to continue or, possibly, expand operations. To date, the lender has chosen not to exercise any of its remedies, though we agreed to put $3,930,000 of ATM proceeds in an interest bearing account to serve as additional security for the Company’s obligations under the Current Credit Facility. We remain in constructive discussions with Webster Bank regarding potential extension of these obligations but there can be no assurance that an agreement will be reached.

Note 12. COMMITMENTS AND CONTINGENCIES

On October 2, 2018, Contract Pharmacal Corp. (“Contract Pharmacal”) commenced an action, relating to a Sublease entered into between the Company and Contract Pharmacal in May 2018 with respect to the property that was formerly occupied by the Company’s former subsidiary WMI, at 110 Plant Avenue, Hauppauge, New York. In the action, Contract Pharmacal sought damages for an amount in excess of $1,000,000 for the Company’s alleged violation of the terms of the subject sublease, specifically the failure to make the entire premises available by what it claims was the Sublease commencement date. The validity of the action is extremely suspect in that the subject sublease had no specific commencement date and Contract Pharmacal ultimately received all the space. Discovery was conducted and the Plaintiff moved for summary judgement and to amend its complaint to add a new cause of action all of which the company opposed. On July 8, 2021, the Court denied Contract Pharmacal’s motion for summary judgement and to add an additional cause of action. In the Order, the Court granted Contract Pharmacal’s Motions to drop its claim for specific performance and to amend its Complaint to reduce its claim for damages to $700,000 both of which benefit the Company. Following the Court’s decision, Contract Pharmacal filed a Motion to reargue its original motion which the Company opposed. The Court denied that motion on November 30, 2021 and then on March 10, 2022, Contract Pharmacal filed an appeal of the Court’s decision with the Appellate Division of the State of New York. The Company opposed that action. The Company was again successful as the Appellate Division upheld the lower court’s denial of Contract Pharmacal’s motion for summary judgement and its motion to amend its Complaint. Contract Pharmacal has now submitted a motion to the Appellate Division requesting leave to reargue the court’s denial of its original appeal. The Company will oppose that motion. The Appellate Division has yet to act in respect to Contract Pharmacal’s most recent motion to reargue the Court’s denial of the original appeal. The Company continues to dispute the validity of the claims asserted by Contract Pharmacal and intends to contest them vigorously

From time to time the Company may be engaged in various lawsuits and legal proceedings in the ordinary course of business. The Company is currently not aware of any legal proceedings the ultimate outcome of which, in its judgment based on information currently available, would have a material adverse effect on its business, financial condition or operating results. There are no proceedings in which any of the Company’s directors, officers or affiliates, or any registered or beneficial stockholder of its common stock, is an adverse party or has a material interest adverse to our interest.

On July 4, 2025, the One Big Beautiful Bill was enacted (“OBBBA”), introducing significant and wide-ranging changes to the U.S. federal tax system. Significant components include restoration of 100% accelerated tax depreciation on qualifying property including expansion to cover qualified production property. Another major aspect includes the return to immediate expensing of domestic research and experimental expenditures (“R&E”) which in some cases may include retroactive application back to 2021 for businesses with gross receipts of less than $31 million or accelerated tax deductions of R&E that was previously capitalized for larger businesses. The legislation also reinstates EBITDA-based interest deductions for tax purposes and makes several business tax incentives permanent. Less favorable business provisions include limitations on tax deductions

for charitable contributions. In accordance with ASC 740, the Company recognized the effects of the OBBBA in the period that included the enactment date. The Company continues to evaluate the ongoing effects of the OBBBA, including the interaction of the enacted provisions with its existing tax attributes and elections.

During the years ended December 31, 2025 and 2024, the Company recorded a valuation allowance equal to its net deferred tax assets. The Company determined that due to a recent history of net losses, at this time sufficient uncertainty exists regarding the future realization of these deferred tax assets through future taxable income. If, in the future, the Company believes that it is more likely than not that these deferred tax benefits will be realized, the valuation allowances will be reduced or eliminated. With a full valuation allowance, any change in the deferred tax asset or liability is fully offset by a corresponding change in the valuation allowance. At December 31, 2025 and 2024, the Company provided a valuation allowance on its net deferred tax assets of $8,306,000 and $8,091,000, respectively. The Company’s valuation allowance increased by $215,000 and $188,000 for the years ended December 31, 2025 and 2024, respectively.

As of December 31, 2025, the Company had a Federal net operating loss carry forward of approximately $22,396,000, of which approximately $14,016,000 expires from 2033 through 2037 and $8,380,000 does not expire. In addition, the Company has net operating loss carryforwards from various states of approximately $4,492,000 which expire starting in 2035.

The utilization of the Company’s net operating losses may be subject to a U.S. federal limitation due to the “change in ownership provisions” under Section 382 of the Internal Revenue Code and other similar limitations in various state jurisdictions. Such limitations may result in a reduction of the amount of net operating loss carryforwards in future years and possibly the expiration of certain net operating loss carryforwards before their utilization.

During the year ended December 31, 2025, the Company generated Section 48 Energy Property Tax Credits related to qualifying energy property. The Company sold these credits to an unrelated third party. The impact of the sale are reflected in the transferable credit line items outlined in the rate reconciliation above.

At December 31, 2025 and 2024, the Company had no material unrecognized tax benefits and no adjustments to liabilities or operations were required. The Company does not expect that its unrecognized tax benefits will materially increase within the next twelve months. The Company recognizes interest and penalties related to uncertain tax positions in interest expense. As of December 31, 2025, and 2024, the Company has not recorded any provisions for accrued interest and penalties related to uncertain tax positions.

In certain cases, the Company’s uncertain tax positions are related to tax years that remain subject to examination by the relevant tax authorities. The Company files federal and state income tax returns in jurisdictions with varying statutes of limitations. The 2022 through 2025 tax years generally remain subject to examination by federal and state tax authorities.

There were no payments made in relation to income taxes for the year ending December 31, 2025.

During the years ended December 31, 2025 and 2024, the Company granted options to purchase 60,000 and 80,000 shares of common stock, respectively, to certain of its employees and directors.

The Company recorded stock-based compensation expense for certain employees and members of the Company’s Board of Directors of $182,000 and $317,000 in its consolidated statements of operations for the years ended December 31, 2025 and 2024, respectively, and such amounts were included as a component of operating expenses on the consolidated statement of operations.

The expected life is the number of years that the Company estimates, based upon history, that the options will be outstanding prior to exercise or forfeiture. Expected life is determined using the “simplified method” permitted by Staff Accounting Bulletin No. 107. In addition to the inputs referenced above regarding the option pricing model, the Company adjusts the stock-based compensation expense for estimated forfeiture rates that are revised prospectively according to forfeiture experience. The stock volatility factor is based on the Company’s experience.

The fair value of the RSUs vested during the year ended December 31, 2025 was $318,000. All of the RSUs vested were net settled such that the Company withheld shares with a value equivalent to the employees’ obligation for the applicable income and other employment taxes, and remitted cash to the appropriate taxing authorities. The total shares withheld were 38,018 and were valued on their vesting date as determined by the Company’s closing stock price. Total payments to taxing authorities for tax obligations were $127,000.

As of December 31, 2025, there was $373,000 of unrecognized compensation cost related to non-vested RSUs, which is to be recognized over the remaining weighted average vesting period of 1.25 years.

Note 15. SEGMENT INFORMATION

The Company operates as one operating segment. The Company’s CODM is its Chief Executive Officer, who reviews financial information presented on a consolidated basis. The CODM used consolidated sales, gross margin and net income (loss) to assess financial performance and allocate resources. These financial metrics are used by the CODM to make key operating decisions, such as the need to allocate its budget to operating expenses and invest in additional equipment. The segment assets are equal to the assets presented in the consolidated balance sheets.

The significant expenses that are regularly provided to the CODM are disclosed in the consolidated statements of operations as a part of the consolidated net income (loss). See the consolidated financial statements for all financial information regarding the Company’s operating segment.

All revenues of the Company are earned in the United States of America.

The Company’s long-lived tangible assets, as well as the Company’s operating lease right-of use assets recognized on the Consolidated Balance Sheets were located in the United States.

Note 16. SUBSEQUENT EVENTS

On February 17, 2026, the Company filed a Current Report on Form 8-K (the “Merger 8-K”), with respect to the Agreement and Plan of Merger (the “Merger Agreement”) the Company and Transitory Air Sub LLC, its wholly owned subsidiary (“Merger Sub”), entered into on February 16, 2026, with Tenax Aerospace Acquisition, LLC, a Delaware limited liability company (“Tenax”). Upon consummation of the Merger Agreement Tenax, will become a wholly owned Subsidiary of the Company.

Pursuant to the Merger Agreement, the Company will issue shares of its common stock (the “Merger Consideration”) to the holders of the membership interests of Tenax at the Closing (the “Tenax Members”). A portion of the Merger Consideration allocated in respect of membership interests of Tenax underlying certain Tenax warrants that remain unexercised as of the Closing, if any, will be reserved by the Company for future issuance upon the exercise of such warrants. The number of shares of the Company’s common stock to be issued to the Tenax Members will be adjusted based on a calculation of AIR Net Indebtedness (as defined in the Merger Agreement). Based on the amount of AIR Net Indebtedness as of December 31, 2025, the calculation would result in the issuance of approximately 112.5 million shares of the Company’s Common Stock. Consequently, based upon the calculation of the Merger Consideration as of December 31, 2025, following the closing of the Merger, the Tenax Members will collectively own approximately 95% of the outstanding shares of our Common stock.

Independent Auditors’ Review Report

The Board of Directors
Tenax Aerospace Acquisition, LLC:

Results of Review of Consolidated Interim Financial Information

We have reviewed the consolidated financial statements of Tenax Aerospace Acquisition, LLC and its subsidiaries (the Company), which comprise the consolidated balance sheet as of March 31, 2026, and the related consolidated statements of income, (deficit)/equity and cash flows for the three-month periods ended March 31, 2026 and March 31, 2025, and the related notes (collectively referred to as the consolidated interim financial information).

Based on our reviews, we are not aware of any material modifications that should be made to the accompanying consolidated interim financial information for it to be in accordance with U.S. generally accepted accounting principles.

Basis for Review Results

We conducted our reviews in accordance with auditing standards generally accepted in the United States of America (GAAS) applicable to reviews of interim financial information. A review of consolidated interim financial information consists principally of applying analytical procedures and making inquiries of persons responsible for financial and accounting matters. A review of consolidated interim financial information is substantially less in scope than an audit conducted in accordance with GAAS, the objective of which is an expression of an opinion regarding the financial information as a whole, and accordingly, we do not express such an opinion. We are required to be independent of the Company and to meet our other ethical responsibilities in accordance with the relevant ethical requirements relating to our reviews. We believe that the results of the review procedures provide a reasonable basis for our conclusion.

Responsibilities of Management for the Consolidated Interim Financial Information

Management is responsible for the preparation and fair presentation of the consolidated interim financial information in accordance with U.S. generally accepted accounting principles and for the design, implementation, and maintenance of internal control relevant to the preparation and fair presentation of consolidated interim financial information that is free from material misstatement, whether due to fraud or error.

Report on Consolidated Balance Sheet as of December 31, 2025

We have previously audited, in accordance with GAAS, the consolidated balance sheet as of December 31, 2025, and the related consolidated statements of income, changes in equity, and cash flows for the year then ended (not presented herein); and we expressed an unmodified audit opinion on those audited consolidated financial statements in our report dated April 15, 2026. In our opinion, the accompanying consolidated balance sheet of the Company as of December 31, 2025 is consistent, in all material respects, with the audited consolidated financial statements from which it has been derived.

TENAX AEROSPACE ACQUISITION, LLC
Notes to Consolidated Financial Statements
(Unaudited)

(1)    Nature of Operations, Corporate Structure, and Summary of Significant Accounting Policies

(a)    Nature of Operations and Corporate Structure

Tenax Aerospace Acquisition, LLC (the Company) was formed in 2017 as a limited liability company under the Delaware Limited Liability Company Act to be the holding company of Tenax Aerospace Holdings, LLC (TAH).

The business of the Company is conducted by its wholly owned subsidiary, TAH and its subsidiaries. TAH earns revenues predominantly through providing special mission aircraft and related services to the United States (U.S.) government and commercial customers, including aerial fire suppression, airborne ISR and other special missions. Additionally, the Company generates revenue through selling systems engineering, electronic system design development, integration and modification, mapping and testing, sensor testing, training and live operations and support to the federal government and government contractors in the U.S.

(b)    Principles of Consolidation

The consolidated financial statements include the accounts of the Company and its wholly owned subsidiary, Tenax Holdco, LLC (Holdco). Tenax Intermediate Holdco, LLC (Intermediate Holdco) is wholly owned by Holdco, and TAH is a wholly owned subsidiary of Intermediate Holdco.

The accompanying consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP” or “U.S. GAAP”) and applicable rules and regulations regarding interim financial reporting, and include the accounts of the Company, its wholly owned subsidiaries, as required by GAAP. Accordingly, they do not include all of the information and footnotes required by GAAP for annual audited financial statements. The unaudited consolidated financial statements have been prepared on a basis consistent with the audited consolidated financial statements and include all adjustments, which are normal and recurring in nature, necessary for fair financial statement presentation. These consolidated financial statements and notes thereto should be read in conjunction with the Company’s most recently completed annual consolidated financial statements.

All significant intercompany accounts and transactions have been eliminated in consolidation.

(c)     Use of Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

(d)    Accounts Receivable

Accounts receivable are stated at the amount the Company expects to collect from outstanding balances. The Company provides an allowance for credit losses, which is based upon a review of outstanding receivables, historical collection information, current market conditions and reasonable and supportable forecasts of future economic conditions. No allowance for credit losses was deemed necessary for any period presented.

(e)     Property and Equipment

Property and equipment acquisitions are recorded at cost and are depreciated on a straight — line basis over the estimated useful life of each asset, which ranges from 1 to 15 years, with estimated salvage values primarily ranging from 0% to 20%. Special mission — related modifications to aircraft

are depreciated over the useful life of the aircraft when such modifications provide utility beyond the specific lease arrangement. If the mission — specific modifications provide no long — term value, such custom modifications are depreciated over the expected lease term.

Property and equipment are summarized as follows at March 31, 2026 and December 31, 2025:

(f)     Deferred Financing Costs

In connection with the issuance of debt during the three months ended March 31, 2026 and the year ended March 31, 2025, the Company incurred financing costs totaling approximately $2,400,000 and $0, respectively. These costs have been deferred and are being amortized over the term of the related debt. Amortization expense is included in interest expense in the accompanying consolidated statements of income and approximated $359,000 and $163,000 for the three months ended March 31, 2026 and 2025, respectively. The remaining unamortized deferred financing cost is shown net of long-term debt in the accompanying consolidated balance sheets. See Note 4 for additional information about long-term debt.

(g)    Long-Lived Asset Impairment

The Company evaluates the recoverability of the carrying value of long-lived assets, such as property and equipment and purchased intangible assets subject to amortization, whenever events or circumstances indicate the carrying amount may not be recoverable. If a long-lived asset is tested for recoverability and the undiscounted estimated future cash flows expected to result from the use and eventual disposition of the asset is less than the carrying amount of the asset, the asset cost is adjusted to fair value, and an impairment loss is recognized as the amount by which the carrying amount of a long-lived asset exceeds its fair value.

No asset impairment was recognized during the three months ended March 31, 2026 and 2025.

(h)    Investment

The Company held a total interest of 5.922% in Overwatch Imaging, LLC (Overwatch) at March 31, 2026 and December 31, 2025 and accounts for this investment under ASC 321 using the measurement alternative, whereby the investment is carried at cost, adjusted for observable price changes and impairment. The Company did not buy or sell any shares for any period presented. The amount recorded as the investment in Overwatch at March 31, 2026 and December 31, 2025 was $1,357,048 and was included in other noncurrent assets on the consolidated balance sheets.

(i)     Goodwill and Other Intangible Assets

Goodwill represents the excess purchase price over the estimated fair value of net assets acquired in a business combination. Goodwill is tested annually for impairment or more frequently if impairment indicators are present. When impairment indicators are identified, the Company compares the reporting

F-58

Table of Contents

Notes to Consolidated Financial Statements

unit’s fair value to its carrying amount, including goodwill. An impairment loss is recognized as the difference, if any, between the reporting unit’s carrying amount and its fair value, to the extent the difference does not exceed the total amount of goodwill allocated to the reporting unit.

Intangible assets with estimable or determinable useful lives are amortized over their respective estimated useful lives in a manner that approximates the economic benefits consumed and are periodically reviewed for impairment.

(j)     Income Taxes

The Company’s income will be taxed as a partnership for both federal and state income tax purposes. Taxable income or loss is therefore reported to the individual members for inclusion in their respective tax returns, and no provision for federal and state income taxes is included in these consolidated financial statements.

(k)    Revenue Recognition

Service and product income is recognized in accordance with Financial Accounting Standards Codification (ASC) Topic 606, Revenue from Contracts with Customers, when the Company satisfies its performance obligations under the terms of its contracts and control of goods or services is transferred to customers in an amount that reflects the consideration the Company expects to receive. This process includes identifying the contract with a customer, identifying distinct performance obligations, determining the transaction price, allocating the transaction price to performance obligations based on relative standalone selling prices, and recognizing revenue as the performance obligations are satisfied.

Service and product income is primarily generated from government contracts. The Company’s subsidiary, DST, provides specially modified aircraft for aerial sensor testing, training, and live operations, as well as unmanned aircraft systems, maritime services, logistical support and aircraft modification services. Because DST retains a substantive right of substitution, these arrangements do not constitute leases under ASC Topic 842, Leases. Revenue from these contracts is generally recognized over time as services are performed. For performance obligations satisfied over time, revenue is recognized using methods that best depict the transfer of control to the customer, including the right-to-invoice method, straight-line recognition, or the percentage-of-completion cost-to-cost method.

The Company has elected the practical expedient to not separate lease and non-lease components for certain operating leases that meet the criteria under ASC Topic 842. Services associated with these arrangements, including operations performed outside the continental United States, are generally provided under fixed-price contracts. Revenue from fixed-price service contracts is recognized over the contractual service period based on the related performance obligations. For sales-type leases, lease components are accounted for under ASC Topic 842, while non-lease components, including modification, operations, and maintenance services, are accounted for under ASC Topic 606.

Aircraft rental income is derived from operating leases of aircraft. The Company recognizes aircraft rental income on a straight-line basis over the non-cancelable term of the lease in accordance with ASC Topic 842.

Aircraft flight hour income represents variable consideration under aircraft lease arrangements and is recognized as flight hours are flown at the contractual hourly rates specified in the related lease agreements.

Other income consists of miscellaneous revenue items that are recognized when earned and realizable, including cost-reimbursable items such as travel and other direct costs that are billed to customers.

F-59

(1)    Nature of Operations, Corporate Structure, and Summary of Significant Accounting Policies (cont.)

Contract costs include direct material and labor costs and indirect costs related to contract performance. Selling, general, and administrative costs are expensed as incurred. Provisions for estimated losses on uncompleted contracts are recognized in the period such losses are identified. Revisions to cost estimates and profitability are recognized in the period in which changes are determined.

Many of the Company’s contracts are for one-year terms with annual renewal options. Accordingly, for those contracts, contract-related assets and liabilities are classified as current. Due to the inherent uncertainty in estimating costs and revenues, it is reasonably possible that estimates used in revenue recognition may change in the near term.

(l)     Fair Value Measurements

The Company utilizes valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs to the extent possible. The Company determines fair value based on assumptions that market participants would use in pricing an asset or liability in the principal or most advantageous market. When considering market participant assumptions in fair value measurements, the following fair value hierarchy distinguishes between observable and unobservable inputs, which are categorized in one of the following levels:

        Level 1 Inputs:    Unadjusted quoted prices in active markets for identical assets or liabilities accessible to the reporting entity at the measurement date.

        Level 2 Inputs:    Other than quoted prices included in Level 1 inputs that are observable for the asset or liability, either directly or indirectly, for substantially the full term of the asset or liability.

        Level 3 Inputs:    Unobservable inputs for the asset or liability used to measure fair value to the extent that observable inputs are not available, thereby allowing for situations in which there is little, if any, market activity for the asset or liability at the measurement date.

The carrying amounts of the Company’s financial instruments, including cash and cash equivalents, accounts receivable, accounts payable, and accrued liabilities, approximate their respective fair values due to the short-term nature of those instruments.

(m)   Leases-Lessor Arrangements

The Company, as part of its business, enters into lease arrangements with its customers that grant the customer the right to use one or more specific modified aircraft. The arrangements range from a dry lease that is limited to the lease of the aircraft with certain other services provided (e.g., maintenance services) to a wet lease where the Company not only supplies the aircraft but also supplies the crew and provides certain other services (e.g., maintenance and certain mission specific services). The Company determines if an arrangement with its customer is or contains a lease at the lease inception date by evaluating whether the arrangement conveys the right to use an identified asset and whether the customer obtains substantially all of the economic benefits from and has the ability to direct the use of the asset.

If it is determined that the contract is or contains a lease, the Company then assesses lease classification considering the lease term and assumptions that exist at the lease commencement date. Depending on this assessment, the Company will account for its lease agreements as either operating, direct financing, or sales type leases, with the resulting accounting dependent on the lease classification.

For leases classified as operating leases, the underlying aircraft remains on the Company’s consolidated balance sheets and continues to be depreciated in accordance with the Company’s depreciation policies for similar assets. Rental income for operating leases is recognized on a straight- line basis over the

F-60

lease term. For the leases that are classified as direct financing or sales type leases, the aircraft is derecognized, and a net investment in the leased aircraft is recognized on the Company’s consolidated balance sheet. The net investment consists of a lease receivable and the expected unguaranteed residual value of the leased aircraft, each of which is determined on a discounted basis. The expected unguaranteed residual value of the aircraft is based on the Company’s estimate of the value of the aircraft at the expiration of the lease. Interest income is recognized on the net investment in the lease using the effective interest method to produce a consistent yield over the lease term.

The Company’s lease agreements with its customers include fixed lease payments and, in certain scenarios, variable lease payments based on the number of flight hours. In addition to the lease payments, certain of the Company’s contracts include non-lease components which come in various forms, such as maintenance services, flight crew, technicians, and fuel. Topic 842 requires that the consideration in the contract be allocated between lease and non-lease components on a relative standalone selling price basis, unless a provided practical expedient is elected. Specifically, Topic 842 includes a practical expedient that permits a lessor, as an accounting policy election by underlying asset class, to choose not to separate non lease components from lease components when the lease component, if accounted for separately, would be classified as an operating lease and when the timing and pattern of transfer for the lease and non-lease components associated with the lease component are the same. The Company has elected this practical expedient for all of its customer aircraft lease agreements that meet these conditions.

The Company assesses the lease term at the lease commencement date. The lease term is defined as the noncancelable period plus any period subject to a renewal option that is deemed reasonably certain of being exercised or subject to a termination option that is reasonably certain of not being exercised. Certain of the Company’s lease contracts do include renewal options that allow the customer to extend the lease term for an additional period of 6 months to 7 years. The Company typically does not include the renewal options as part of the lease term, as it does not believe that it is reasonably certain that such options will be exercised.

The Company has included additional disclosures about its lessor leasing activity in Note 6.

(n)    Leases-Lessee Arrangements

The Company leases office space, hangar space and aircraft under operating leases. The aircraft subject to operating lease agreements are used as part of the Company’s core operations and leased to a certain customer via a sublease. The Company determines if an arrangement is or contains a lease at the lease inception date by evaluating whether the arrangement conveys the right to use an identified asset and whether the Company obtains substantially all of the economic benefits from and has the ability to direct the use of the asset.

Topic 842 defines a short-term lease as a lease with a lease term of twelve months or less and that does not include a purchase option that is reasonably certain of being exercised. A lessee, as an accounting policy, can elect to not recognize short- term leases on the balance sheet, but rather recognize the related lease cost on a straight- line basis over the short-term lease period. The Company has elected this policy for all classes of assets.

At the lease commencement date, the Company recognizes a lease liability and a ROU asset representing its right to use the underlying asset over the lease term. The initial measurement of the lease liability is calculated on the basis of the present value of the remaining lease payments, and the ROU asset is measured on the basis of this liability, and adjusted as necessary by prepaid and accrued rent, lease incentives and initial direct costs. The subsequent measurement of a lease is dependent on whether

the lease is classified as an operating lease or a finance lease. Operating lease cost is recognized on a straight- line basis over the lease term in the consolidated statement of income. Finance lease cost is comprised of separate interest and amortization components and is presented in the consolidated statement of income. The Company’s leasing activities are currently limited to operating leases.

Topic 842 requires that the consideration in the contract be allocated between lease and non-lease components on a relative standalone price basis unless a provided practical expedient is elected. Specifically, Topic 842 includes a practical expedient that permits a lessee, as an accounting policy election by underlying asset class, to choose not to separate lease and non-lease components and instead account for the separate lease component and associated non lease components on a combined basis. The Company has elected to apply this practical expedient for all classes of assets.

For leases acquired in business combinations, the Company will retain the lease classification used by the acquiree unless the Company modifies a lease in a manner that is not accounted for as a separate contract. For leases in which the acquiree was the lessee, the Company will measure the lease liability at the present value of the remaining lease payments, as if the acquired lease were a new lease of the Company at the acquisition date. The Company will measure the ROU asset at the same amount as the lease liability as adjusted to reflect favorable or unfavorable terms of the lease when compared with market terms. Acquired leasehold improvements will be amortized over the shorter of the useful life of the assets and the remaining lease term at the date of acquisition. However, if the lease transfers ownership of the underlying asset to the lessee, or the lessee is reasonably certain to exercise an option to purchase the underlying asset, the lessee shall amortize the leasehold improvements to the end of their useful life.

The Company’s leases require other payments such as costs related to service components, real estate taxes, common area maintenance, and insurance. These costs are generally variable in nature and based on the actual costs incurred and required by the lease. As the result of the Company’s election to not separate lease and non-lease components, all variable costs associated with the lease are expensed in the period incurred and presented and disclosed as variable lease costs. The Company’s lease agreements do not contain any residual value guarantees or material restrictive financial covenants. The Company does not have any leases that have not yet commenced that create significant rights and obligations for the lessee.

The Company’s leases expire over the next 22 years and include options that grant the Company the ability to renew or extend the leases, with the renewal options extending the lease for an additional 1 to 10 years, depending on the lease. When determining the lease term, the Company does not include renewal options unless the renewals are deemed to be reasonably certain of being exercised at the lease commencement date.

Topic 842 requires that a lessee use the rate implicit in the lease when measuring the lease liability and ROU asset, unless that rate is not readily determinable. When the rate implicit in the lease is not readily determinable, the Company uses its incremental borrowing rate. The Company’s incremental borrowing rate represents the rate of interest that the Company would have to pay to borrow, on a collateralized basis, an amount equal to the lease payments, over a similar term and in a similar economic environment. The incremental borrowing rate is determined for each lease based on the lease term and the underlying asset, using observable market data and Company specific credit assumptions.

The Company applies an updated incremental borrowing rate for new leases and upon remeasurement events for existing leases.

The Company has included additional disclosures about its operating leases in Note 7.

(1)    Nature of Operations, Corporate Structure, and Summary of Significant Accounting Policies (cont.)

(o)    Derivatives

The Company uses interest rate-related derivative instruments to manage its exposure related to changes in interest rates on its variable rate debt instruments. All derivative instruments are recognized as either assets or liabilities in the balance sheet at their respective fair values. The Company does not apply hedge accounting to its outstanding interest rate cap and interest rate swap; therefore, changes in the fair values of the derivative instruments are recognized in earnings each reporting period.

(p)    Warrant Liabilities

The Company evaluates warrants issued in connection with financing transactions to determine whether such instruments are freestanding financial instruments and whether they should be classified as liabilities or equity in accordance with ASC 480, Distinguishing Liabilities from Equity, and other applicable accounting guidance.

Warrants that include provisions that could require the Company to repurchase its equity instruments for cash or other assets, or that otherwise meet the criteria for liability classification under ASC 480, are classified as warrant liabilities. Warrant liabilities are initially recognized at fair value on the issuance date and are subsequently remeasured at fair value at each reporting date until settlement, expiration or exercise.

Changes in the fair value of warrant liabilities are recognized in other expense in the consolidated statements of income.

The fair value of warrant liabilities is determined using valuation techniques that are appropriate in the circumstances and for which sufficient data are available to measure fair value, maximizing the use of observable inputs and minimizing the use of unobservable inputs. The Company estimates the fair value of its warrant liabilities using the Black-Scholes option pricing model. Significant assumptions used in the valuation include the expected term of the warrants, expected volatility, risk-free interest rate and dividend yield.

Warrant liabilities are classified within Level 3 of the fair value hierarchy due to the use of significant unobservable inputs. See Note 13 for additional information.

(q)    Assets Held for Sale

The Company classifies long-lived assets as held for sale when management commits to a plan to sell the assets and all criteria for held-for-sale classification are met in accordance with ASC 205-20 and ASC 360-10. Upon classification as held for sale, the carrying amounts of such assets are reclassified from property and equipment, net, to current assets within “Assets held for sale” on the consolidated balance sheets.

Assets classified as held for sale are measured at the lower of carrying amount or fair value less cost to sell. Depreciation ceases when assets are classified as held for sale. Assets classified as held for sale are evaluated at each reporting date to determine whether the held-for-sale criteria continue to be met. If the criteria are no longer met, the assets are reclassified as held and used and measured in accordance with the applicable guidance for long-lived assets.

The classification of assets as held for sale does not result in discontinued operations presentation unless the disposition represents a strategic shift that has, or will have, a major effect on the Company’s operations or financial results.

(1)    Nature of Operations, Corporate Structure, and Summary of Significant Accounting Policies (cont.)

(r)     Merger

On February 16, 2026, the Company and Air Industries Group (AIR) entered into an Agreement and Plan of Merger (the Merger Agreement) to combine the Company’s aviation business with AIR’s aerospace manufacturing business. This “reverse merger” will result in the Company owning approximately 95% of AIR’s outstanding shares based on a calculation of “Debt Adjusted AIR Share Price” (as defined) in the Merger Agreement. The merger is subject to AIR shareholder approval, related regulatory filings, U.S. government approvals and other closing conditions customary for transactions of this size and nature.

As the Merger is anticipated to occur subsequent to the consolidated balance sheet date, this subsequent event activity has not been reflected in the accompanying consolidated financial statements as of March 31, 2026.

(2)    Contingent Consideration

The Company had a contingent consideration arrangement associated with the DST acquisition on December 22, 2022. The contingent consideration arrangement, as evidenced by a seller note, required the Company to pay the former owner of DST a payout based on the achievement of certain financial metrics of DST during 2023, 2024, and 2025, with a target amount of $15,000,000, as adjusted higher or lower based on the formula in the seller note, to be paid in three installments, the first during 2024, the second during 2025, and the third during 2026. The fair value of the contingent consideration arrangement at the date of acquisition of $9,300,000 and subsequent remeasurement was estimated by applying the income approach. That measure is based on significant inputs that are not observable in the market, which are referred to as Level 3 inputs (see discussion of the fair value hierarchy at Note 1(l). The final portion of the contingent liability was paid out in February 2026 and as such, at March 31, 2026 and December 31, 2025, the amount reflected as a contingent consideration liability on the consolidated balance sheets of the Company was $0 and $4,716,077, respectively. In February of 2026 and 2025, payments were made to the former owner in the amounts of $4,716,077 and $3,853,013, respectively.

(3)    Goodwill and Customer Relationship Intangibles

The goodwill of $33,202,473 reflected on the Company’s consolidated balance sheets as of March 31, 2026 and December 31, 2025 was associated with the acquisition of DST by the Company in 2022 and the acquisition of TAH by the Company in 2018. There were no changes in the carrying amount of goodwill for the three months ended March 31, 2026 and 2025.

On January 8, 2018, the Company (as initial borrower) and TAH (as successor borrower) entered into a First Lien Credit Agreement (First Lien) with a group of banks and a Second Lien Credit Agreement (Second Lien) with an investment firm. The First Lien was refinanced on August 3, 2022, representing the Amended and Restated First Lien Credit Agreement, and included an increase in the term loan to $85,000,000 and provided for a $15,000,000 revolving line of credit and a $40,000,000 Delayed Draw Term Loan. The maturity date of the First Lien was the earliest of (a) August 3, 2027, (b) the date six months prior to the maturity date of the Second Lien and (c) the date twelve months prior to the maturity date of the Holdco subordinated term loan agreement. The Second Lien was amended on August 3, 2022, which extended the maturity date to July 10, 2025. The First Lien was amended on December 22, 2022, to add an additional term loan in the amount of $40,000,000 and increase the revolving line of credit to $20,000,000. On November 29, 2023, the Company entered into an incremental delayed draw term loan agreement with its lender to provide an additional commitment of $15,000,000.

The First Lien was refinanced on January 23, 2024, representing the Second Amended and Restated Credit Agreement, and included a term loan of $172,500,000 and provided for a $30,000,000 revolving line of credit and a $42,500,000 Delayed Draw Term Loan feature. As part of this refinancing, the Second Lien was paid in full.

On September 9, 2025, the Second Amended and Restated Credit Agreement was amended to provide for (a) a $200,000,000 term loan, (b) a Delayed Draw Term Loan #1 of $40,000,000, (c) a Delayed Draw Term Loan #2 of $60,000,000 (none of which has been drawn through December 31, 2025) and (d) a $30,000,000 revolving line of credit (of which $6,650,000 was drawn as of December 31, 2025).

On January 7, 2026, the Second Amended and Restated Credit Agreement was further amended to provide for (a) a $200,000,000 term loan, (b) a Delayed Draw Term Loan # 1 of $40,000,000, (c) a Delayed Draw Term Loan # 2 of $60,000,000 (of which $ 48,057,153 was drawn as of March 31, 2026) and (d) a 30,000,000 revolving line of credit (of which $6,530,720 was drawn as of March 31, 2026).

(4)    Long-Term Debt (cont.)

On January 7, 2026 the Company entered into a new Second Lien Credit Agreement with an investment firm to provide for Second Lien Debt of $30,000,000. The maturity date of the Second Lien Debt is July 7, 2031. Repayment of the loan principal is due at maturity.

On January 8, 2018, Holdco entered into a $37,500,000 subordinated term loan agreement (the Subordinated Term Loan) with an investment firm. The Subordinated Term Loan, as amended on August 3, 2022, bears interest at a variable rate based on an adjusted Secured Overnight Financing Rate (SOFR), plus applicable margin. Interest is due quarterly; however, Holdco may pay up to 10.0% per annum of such interest in kind by capitalizing such portion of the accrued interest into the principal amount of the Subordinated Term Loan. Under certain conditions as set forth in the First and Second Lien Term Loans, the payment of interest on this borrowing would not be permitted. Under these conditions, the entire accrued interest may be treated as in kind and capitalized into the principal amount of the Subordinated Term Loan. The borrowings under this Subordinated Term Loan agreement are subordinate to the First and Second Liens, collateralized by a security interest in Intermediate Holdco and originally were scheduled to mature on January 4, 2024. The agreement was amended on August 3, 2022, to extend the maturity date to January 4, 2026.

As part of the refinancing of the First Lien Term Loan on August 3, 2022, the Company repaid $21,000,000 on this Subordinated Term Loan. Additionally, on December 22, 2022, the Subordinated Term Loan agreement was amended to make additional term loans in the amount of $5,000,000 under the same terms and conditions. On January 23, 2024, the Subordinated Term Loan was amended to extend the maturity date from January 4, 2026 to January 23, 2027. The Subordinated Term Loan was amended again on December 30, 2024, to extend the maturity date from January 23, 2027 to July 23, 2027.

On January 7, 2026, the Subordinated Term Loan was extinguished, and all previous unamortized financing costs were expensed. Concurrently, Holdco entered into a new subordinated term loan agreement with a different lender, maturing on January 7, 2032. In connection with this new Subordinated Term Loan, Warrants were issued, as further described in Note 13. Repayment of the loan principal is due at maturity. The amount of interest capitalized for the three months ended March 31, 2026 and 2025 was $289,932 and $0, respectively. The amount outstanding was $42,789,932 and $29,471,221 as of March 31, 2026 and December 31, 2025, respectively, and the interest rate was 15.00% and 18.09% at March 31, 2026 and December 31, 2025, respectively.

The variable interest rate is defined in the amended first lien credit agreement as an adjusted Secured Overnight Financing Rate (SOFR) plus applicable margin or a base rate plus applicable margin. The loan may consist of the adjusted SOFR rate, the base rate or a combination thereof, at the borrower’s option.

All indebtedness is collateralized by substantially all of the Company’s property and equipment. In connection with its indebtedness, the Company is required, among other things, to maintain certain financial covenants, which include consolidated leverage and fixed charge ratios, that must be complied with prior to certain distributions being made to its members.

The estimated fair value of the Company’s long-term debt approximates its carrying amount primarily due to the recent amendments of the instruments at market rates.

In connection with certain outside Board of Directors’ investment in Class A-3 units in the Company, the Company received promissory notes in the same amount from such directors secured by the Company’s underlying membership units. These notes bear interest at 4% and are due at the earlier of ten years or a liquidity event, as defined in the note agreements. The membership interest can be purchased by the Company at any time at fair market value, or the director can exercise his right to sell up to 25% of the membership interest to the Company in any year beginning on the fifth anniversary of the measuring date (defined in the director’s equity ownership agreement as January 8, 2018). The notes receivable of $250,000 as of March 31, 2026 and December 31, 2025 have been reflected as a reduction of equity in the accompanying consolidated balance sheets and consolidated statements of equity.

In connection with certain employees’ investment in Class A-3 units in the Company, the Company received promissory notes in the same amount from such employees secured by the Company’s underlying membership units.

The operating agreement provides that the members of the Company will not be liable for obligations or liabilities of the Company, except to the extent provided by the Delaware Limited Liability Company Act of the State of Delaware.

(10)  Profit Sharing Plan

Tenax TM, LLC has a 401(k) profit sharing plan covering substantially all employees. Employees are eligible for matching contributions equal to 100% of their contribution up to 4% of employees’ salaries. Employer contributions to the plan for the three months ended March 31, 2026 and 2025 were $113,758 and $94,058, respectively.

In addition, DST elected to make discretionary profit-sharing contributions in 2026 and 2025. Employer contributions to the plan for the three months ended March 31, 2026 and 2025 were $564,833 and $338,387, respectively.

(11)  Significant Concentrations

The Company earned 57% and 77% of its revenues from two customers for the three months ended March 31, 2026 and 2025, respectively, which receive funding primarily through government contracts. These two customers accounted for approximately 44% and 59% of accounts receivable at March 31, 2026 and 2025, respectively.

(12)  Assets Held for Sale

The Company classified certain aircraft as assets held for sale after determining that the criteria for held-for-sale classification under ASC 205-20 and ASC 360-10 were met. The assets were reclassified from property and equipment, net, to current assets within “Assets held for sale” on the consolidated balance sheets.

As of March 31, 2026 and December 31, 2025, assets held for sale consisted of three and no aircraft, respectively, with an aggregate carrying amount of $27,077,828 and $0, respectively. The assets were measured at the lower of carrying amount or fair value less cost to sell, and no impairment charge was recognized upon classification.

The Company does not expect the disposition of these assets to represent a strategic shift that has, or will have, a major effect on its operations or financial results. Accordingly, the assets held for sale are not presented as discontinued operations.

(13)  Warrants

In connection with the refinancing and recapitalization transactions completed on January 7, 2026 (see Notes 4 and 8), the Company issued four warrant agreements to certain lenders participating in the refinancing transaction. Each warrant agreement was executed contemporaneously and contains substantively identical terms. Accordingly, the warrants are accounted for and presented on a combined basis as a single class of warrants (collectively, the “Warrants”).

F-72

Notes to Consolidated Financial Statements
(Unaudited)

(13)  Warrants (cont.)

The Warrants provide the holders with the right to purchase an aggregate of 411,579 Class A-2 membership units of the Company. The Warrants were issued in conjunction with the Company’s entry into a new subordinated credit facility and related second lien financing arrangements (see Note 4). The Warrants were initially measured at fair value with the debt proceeds allocated between the debt and the warrants using the residual value, with the offset recorded as additional debt discount.

The Warrants have a weighted-average exercise price of $16.67 per unit and are exercisable, in whole or in part, at any time from the issuance date through January 7, 2036, unless earlier exercised or terminated in connection with a Company Sale Event, as defined in the Company’s amended and restated limited liability company agreement.

The Warrants may be exercised through either:

        Cash settlement, or

        Net (cashless) settlement, whereby the Company withholds a number of Class A-2 units with an aggregate fair value equal to the exercise price.

No fractional units are issued upon exercise; any fractional interests are settled in cash. Upon exercise, the holder becomes a member of the Company and is subject to the provisions of the Company’s amended and restated limited liability company agreement.

In the event of a Company Sale Event, the Warrants are subject to automatic exercise and entitle the holders to receive consideration equal to the intrinsic value of the Warrants, payable in cash, equity securities or a combination thereof, consistent with the form of consideration received by holders of Class A-2 units.

Accounting Treatment

The Warrants represent freestanding financial instruments of the Company. The Company evaluated the Warrants under ASC 480, Distinguishing Liabilities from Equity, as well as other applicable accounting guidance, to determine their appropriate classification and measurement.

Because the Warrants include a put feature that would require the Company to repurchase the underlying equity interests for cash, the Warrants are classified as liabilities. The warrant liabilities were initially measured at fair value on the issuance date using a Black Scholes valuation model and are remeasured at fair value at each reporting date, with changes in fair value recognized in earnings. The warrant liabilities are included in other long-term liabilities on the balance sheet. The change in fair value for the three months ended March 31, 2026 was a gain of $54,740.

The Warrants contain customary anti-dilution provisions that provide for adjustments to the number of Class A-2 units issuable upon exercise and/or the exercise price in the event of certain equity issuances, unit splits, reclassifications, business combinations or other dilutive events, subject to specified exclusions.

The Warrants and the Class A-2 units issuable upon exercise are restricted securities and may not be transferred except in compliance with applicable federal and state securities laws and the Company’s limited liability company agreement. Transfers to natural persons are prohibited.

(14)  Subsequent Events

The Company evaluated subsequent events through June 24, 2026, the date on which these consolidated financial statements were available to be issued and determined that no subsequent events occurred that require recognition or disclosure.

Independent Auditors’ Report

The Board of Directors
Tenax Aerospace Acquisition, LLC:

Opinion

We have audited the consolidated financial statements of Tenax Aerospace Acquisition, LLC and its subsidiaries (the Company), which comprise the consolidated balance sheets as of December 31, 2025 and 2024, and the related consolidated statements of income, equity, and cash flows for each of the years in the three-year period ended December 31, 2025, and the related notes to the consolidated financial statements.

In our opinion, the accompanying consolidated financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2025 and 2024, and the results of its operations and its cash flows for each of the years in the three-year period ended December 31, 2025 in accordance with U.S. generally accepted accounting principles.

Basis for Opinion

We conducted our audits in accordance with auditing standards generally accepted in the United States of America (GAAS). Our responsibilities under those standards are further described in the Auditors’ Responsibilities for the Audit of the Consolidated Financial Statements section of our report. We are required to be independent of the Company and to meet our other ethical responsibilities, in accordance with the relevant ethical requirements relating to our audits. We believe that the audit evidence we have obtained is sufficient and appropriate to provide a basis for our audit opinion.

Responsibilities of Management for the Consolidated Financial Statements

Management is responsible for the preparation and fair presentation of the consolidated financial statements in accordance with U.S. generally accepted accounting principles, and for the design, implementation, and maintenance of internal control relevant to the preparation and fair presentation of consolidated financial statements that are free from material misstatement, whether due to fraud or error.

In preparing the consolidated financial statements, management is required to evaluate whether there are conditions or events, considered in the aggregate, that raise substantial doubt about the Company’s ability to continue as a going concern for one year after the date that the consolidated financial statements are available to be issued.

Auditors’ Responsibilities for the Audit of the Consolidated Financial Statements

Our objectives are to obtain reasonable assurance about whether the consolidated financial statements as a whole are free from material misstatement, whether due to fraud or error, and to issue an auditors’ report that includes our opinion. Reasonable assurance is a high level of assurance but is not absolute assurance and therefore is not a guarantee that an audit conducted in accordance with GAAS will always detect a material misstatement when it exists. The risk of not detecting a material misstatement resulting from fraud is higher than for one resulting from error, as fraud may involve collusion, forgery, intentional omissions, misrepresentations, or the override of internal control. Misstatements are considered material if there is a substantial likelihood that, individually or in the aggregate, they would influence the judgment made by a reasonable user based on the consolidated financial statements.

KPMG LLP, a Delaware limited liability partnership, and its subsidiaries are part of
the KPMG global organization of independent member firms affiliated with KPMG
International Limited, a private English company limited by guarantee.

F-74

Table of Contents

In performing an audit in accordance with GAAS, we:

        Exercise professional judgment and maintain professional skepticism throughout the audit.

        Identify and assess the risks of material misstatement of the consolidated financial statements, whether due to fraud or error, and design and perform audit procedures responsive to those risks. Such procedures include examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements.

        Obtain an understanding of internal control relevant to the audit in order to design audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Company’s internal control. Accordingly, no such opinion is expressed.

        Evaluate the appropriateness of accounting policies used and the reasonableness of significant accounting estimates made by management, as well as evaluate the overall presentation of the consolidated financial statements.

        Conclude whether, in our judgment, there are conditions or events, considered in the aggregate, that raise substantial doubt about the Company’s ability to continue as a going concern for a reasonable period of time.

We are required to communicate with those charged with governance regarding, among other matters, the planned scope and timing of the audit, significant audit findings, and certain internal control related matters that we identified during the audit.

TENAX AEROSPACE ACQUISITIONS, LLC
Notes to Consolidated Financial Statements
December 31, 2025, 2024 and 2023

(1)    Nature of Operations, Corporate Structure, and Summary of Significant Accounting Policies

(a)    Nature of Operations and Corporate Structure

Tenax Aerospace Acquisition, LLC (the Company) was formed in 2017 as a limited liability company under the Delaware Limited Liability Company Act to be the holding company of Tenax Aerospace Holdings, LLC (TAH).

The business of the Company is conducted by its wholly owned subsidiary, TAH and its subsidiaries. TAH earns revenues predominantly through providing special mission aircraft and related services to the United States (U.S.) government and commercial customers, including aerial fire suppression, airborne ISR and other special missions. Additionally, the Company generates revenue through selling systems engineering, electronic system design development, integration and modification, mapping and testing, sensor testing, training and live operations and support to the federal government and government contractors in the U.S.

(b)    Principles of Consolidation

The consolidated financial statements include the accounts of the Company and its wholly owned subsidiary, Tenax Holdco, LLC (Holdco). Tenax Intermediate Holdco, LLC (Intermediate Holdco) is wholly owned by Holdco, and TAH is a wholly owned subsidiary of Intermediate Holdco.

TAH’s wholly owned subsidiaries include Tenax Aerospace, LLC (Tenax Aerospace), Tenax Air Services, LLC, Tenax TM, LLC, and Tenax Pilot Services, LLC. On December 22, 2022, TAH, through a newly formed wholly owned subsidiary, DST Acquisition, LLC, acquired DS Technologies, LLC; Falcon Air Service, LLC; N72FE, LLC; N807EV, LLC and JIRO84, LLC (collectively DST).

All significant intercompany accounts and transactions have been eliminated in consolidation.

These consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (GAAP).

(c)     Use of Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

(d)    Accounts Receivable

Accounts receivable are stated at the amount the Company expects to collect from outstanding balances. The Company provides an allowance for credit losses, which is based upon a review of outstanding receivables, historical collection information, current market conditions and reasonable and supportable forecasts of future economic conditions. No allowance for credit losses was deemed necessary as of December 31, 2025 and 2024.

(e)     Property and Equipment

Property and equipment acquisitions are recorded at cost and are depreciated on a straight — line basis over the estimated useful life of each asset, which ranges from 1 to 15 years, with estimated salvage values primarily ranging from 0% to 20%. Special mission — related modifications to aircraft are depreciated over the useful life of the aircraft when such modifications provide utility beyond the specific lease arrangement. If the mission — specific modifications provide no long — term value, such custom modifications are depreciated over the expected lease term.

(f)     Deferred Financing Costs

In connection with the issuance of debt during 2025 and 2024, the Company incurred financing costs totaling approximately $903,000 and $1,317,000, respectively. These costs have been deferred and are being amortized over the term of the related debt. Amortization expense is included in interest expense in the accompanying consolidated statements of income and approximated $739,000, $622,000 and $556,000 for the years ended December 31, 2025, 2024 and 2023, respectively. The remaining unamortized deferred financing cost is shown net of long-term debt in the accompanying consolidated balance sheets. See Note 4 for additional information about long-term debt.

(g)    Long-Lived Asset Impairment

The Company evaluates the recoverability of the carrying value of long-lived assets, such as property and equipment and purchased intangible assets subject to amortization, whenever events or circumstances indicate the carrying amount may not be recoverable. If a long lived asset is tested for recoverability and the undiscounted estimated future cash flows expected to result from the use and eventual disposition of the asset is less than the carrying amount of the asset, the asset cost is adjusted to fair value, and an impairment loss is recognized as the amount by which the carrying amount of a long lived asset exceeds its fair value.

No asset impairment was recognized during the years ended December 31, 2025, 2024 and 2023.

(h)    Investment

The Company held a total interest of 5.922% in Overwatch Imaging, LLC (Overwatch) at December 31, 2025 and 2024 and accounts for this investment using the modified cost method. The Company did not buy or sell any shares in 2025 or 2024. The amount recorded as the investment in Overwatch at December 31, 2025 and 2024 was $1,357,048 and was included in other noncurrent assets on the consolidated balance sheets.

(i)     Goodwill and Other Intangible Assets

Goodwill represents the excess purchase price over the estimated fair value of net assets acquired in a business combination. Goodwill is tested annually for impairment or more frequently if impairment indicators are present. When impairment indicators are identified, the Company compares the reporting unit’s fair value to its carrying amount, including goodwill. An impairment loss is recognized as the difference, if any, between the reporting unit’s carrying amount and its fair value, to the extent the difference does not exceed the total amount of goodwill allocated to the reporting unit.

Intangible assets with estimable or determinable useful lives are amortized over their respective estimated useful lives in a manner that approximates the economic benefits consumed and are periodically reviewed for impairment.

(1)    Nature of Operations, Corporate Structure, and Summary of Significant Accounting Policies (cont.)

(j)     Income Taxes

The Company’s income will be taxed as a partnership for both federal and state income tax purposes. Taxable income or loss is therefore reported to the individual members for inclusion in their respective tax returns, and no provision for federal and state income taxes is included in these consolidated financial statements.

(k)    Revenue Recognition

Service and product income is recognized in accordance with ASC Topic 606, Revenue from Contracts with Customers, when the Company satisfies its performance obligations under the terms of its contracts and control of goods or services is transferred to customers in an amount that reflects the consideration the Company expects to receive. This process includes identifying the contract with a customer, identifying distinct performance obligations, determining the transaction price, allocating the transaction price to performance obligations based on relative standalone selling prices, and recognizing revenue as the performance obligations are satisfied.

Service and product income is primarily generated from government contracts. The Company’s subsidiary, DST, provides specially modified aircraft for aerial sensor testing, training, and live operations, as well as unmanned aircraft systems, maritime services, logistical support and aircraft modification services. Because DST retains a substantive right of substitution, these arrangements do not constitute leases under ASC Topic 842. Revenue from these contracts is generally recognized over time as services are performed. For performance obligations satisfied over time, revenue is recognized using methods that best depict the transfer of control to the customer, including the right-to-invoice method, straight-line recognition, or the percentage-of-completion cost-to-cost method.

The Company has elected the practical expedient to not separate lease and non-lease components for certain operating leases that meet the criteria under ASC Topic 842. Services associated with these arrangements, including operations performed outside the continental United States, are generally provided under fixed-price contracts. Revenue from fixed-price service contracts is recognized over the contractual service period based on the related performance obligations. For sales-type leases, lease components are accounted for under ASC Topic 842, while non-lease components, including modification, operations, and maintenance services, are accounted for under ASC Topic 606.

Aircraft rental income is derived from operating leases of aircraft. The Company recognizes aircraft rental income on a straight-line basis over the non-cancelable term of the lease in accordance with Financial Accounting Standards Codification (“ASC”) Topic 842, Leases.

Aircraft flight hour income represents variable consideration under aircraft lease arrangements and is recognized as flight hours are flown at the contractual hourly rates specified in the related lease agreements.

Other income consists of miscellaneous revenue items that are recognized when earned and realizable, including cost-reimbursable items such as travel and other direct costs that are billed to customers.

Contract costs include direct material and labor costs and indirect costs related to contract performance. Selling, general, and administrative costs are expensed as incurred. Provisions for estimated losses on uncompleted contracts are recognized in the period such losses are identified. Revisions to cost estimates and profitability are recognized in the period in which changes are determined.

Many of the Company’s contracts are for one-year terms with annual renewal options. Accordingly, for those contracts, contract-related assets and liabilities are classified as current. Due to the inherent uncertainty in estimating costs and revenues, it is reasonably possible that estimates used in revenue recognition may change in the near term.

(l)     Fair Value Measurements

The Company utilizes valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs to the extent possible. The Company determines fair value based on assumptions that market participants would use in pricing an asset or liability in the principal or most advantageous market. When considering market participant assumptions in fair value measurements, the following fair value hierarchy distinguishes between observable and unobservable inputs, which are categorized in one of the following levels:

        Level 1 Inputs:    Unadjusted quoted prices in active markets for identical assets or liabilities accessible to the reporting entity at the measurement date.

        Level 2 Inputs:    Other than quoted prices included in Level 1 inputs that are observable for the asset or liability, either directly or indirectly, for substantially the full term of the asset or liability.

        Level 3 Inputs:    Unobservable inputs for the asset or liability used to measure fair value to the extent that observable inputs are not available, thereby allowing for situations in which there is little, if any, market activity for the asset or liability at the measurement date.

(m)   Leases-Lessor Arrangements

The Company, as part of its business, enters into lease arrangements with its customers that grant the customer the right to use one or more specific modified aircraft. The arrangements range from a dry lease that is limited to the lease of the aircraft with certain other services provided (e.g., maintenance services) to a wet lease where the Company not only supplies the aircraft but also supplies the crew and provides certain other services (e.g., maintenance and certain mission specific services). The Company determines if an arrangement with its customer is or contains a lease at the lease inception date by evaluating whether the arrangement conveys the right to use an identified asset and whether the customer obtains substantially all of the economic benefits from and has the ability to direct the use of the asset.

If it is determined that the contract is or contains a lease, the Company then assesses lease classification considering the lease term and assumptions that exist at the lease commencement date. Depending on this assessment, the Company will account for its lease agreements as either operating, direct financing, or sales type leases, with the resulting accounting dependent on the lease classification.

For leases classified as operating leases, the underlying aircraft remains on the Company’s consolidated balance sheets and continues to be depreciated in accordance with the Company’s depreciation policies for similar assets. Rental income for operating leases is recognized on a straight- line basis over the lease term. For the leases that are classified as direct financing or sales type leases, the aircraft is derecognized, and a net investment in the leased aircraft is recognized on the Company’s consolidated balance sheet. The net investment consists of a lease receivable and the expected unguaranteed residual value of the leased aircraft, each of which is determined on a discounted basis. The expected unguaranteed residual value of the aircraft is based on the Company’s estimate of the value of the aircraft at the expiration of the lease. Interest income is recognized on the net investment in the lease using the effective interest method to produce a consistent yield over the lease term.

The Company’s lease agreements with its customers include fixed lease payments and, in certain scenarios, variable lease payments based on the number of flight hours. In addition to the lease payments, certain of the Company’s contracts include non-lease components which come in various forms, such as maintenance services, flight crew, technicians, and fuel. Topic 842 requires that the consideration in the contract be allocated between lease and non-lease components on a relative standalone selling price basis, unless a provided practical expedient is elected. Specifically, Topic 842

includes a practical expedient that permits a lessor, as an accounting policy election by underlying asset class, to choose not to separate non lease components from lease components when the lease component, if accounted for separately, would be classified as an operating lease and when the timing and pattern of transfer for the lease and non-lease components associated with the lease component are the same. The Company has elected this practical expedient for all of its customer aircraft lease agreements that meet these conditions.

The Company assesses the lease term at the lease commencement date. The lease term is defined as the noncancelable period plus any period subject to a renewal option that is deemed reasonably certain of being exercised or subject to a termination option that is reasonably certain of not being exercised. Certain of the Company’s lease contracts do include renewal options that allow the customer to extend the lease term for an additional period of 6 months to 5 years. The Company typically does not include the renewal options as part of the lease term, as it does not believe that it is reasonably certain that such options will be exercised.

The Company has included additional disclosures about its lessor leasing activity in Note 6.

(n)    Leases-Lessee Arrangements

The Company leases office space, hangar space and an aircraft under operating leases. The aircraft subject to an operating lease agreement is used as part of the Company’s core operations and leased to a certain customer via a sublease. The Company determines if an arrangement is or contains a lease at the lease inception date by evaluating whether the arrangement conveys the right to use an identified asset and whether the Company obtains substantially all of the economic benefits from and has the ability to direct the use of the asset.

Topic 842 defines a short-term lease as a lease with a lease term of twelve months or less and that does not include a purchase option that is reasonably certain of being exercised. A lessee, as an accounting policy, can elect to not recognize short-term leases on the balance sheet, but rather recognize the related lease cost on a straight-line basis over the short-term lease period. The Company has elected this policy for all classes of assets.

At the lease commencement date, the Company recognizes a lease liability and a ROU asset representing its right to use the underlying asset over the lease term. The initial measurement of the lease liability is calculated on the basis of the present value of the remaining lease payments, and the ROU asset is measured on the basis of this liability, and adjusted as necessary by prepaid and accrued rent, lease incentives, and initial direct costs. The subsequent measurement of a lease is dependent on whether the lease is classified as an operating lease or a finance lease. Operating lease cost is recognized on a straight- line basis over the lease term in the consolidated statement of income. Finance lease cost is comprised of separate interest and amortization components and is presented in the consolidated statement of income. The Company’s leasing activities are currently limited to operating leases.

Topic 842 requires that the consideration in the contract be allocated between lease and non-lease components on a relative standalone price basis unless a provided practical expedient is elected. Specifically, Topic 842 includes a practical expedient that permits a lessee, as an accounting policy election by underlying asset class, to choose not to separate lease and non-lease components and instead account for the separate lease component and associated non lease components on a combined basis. The Company has elected to apply this practical expedient for all classes of assets.

For leases acquired in business combinations, the Company will retain the lease classification used by the acquiree unless the Company modifies a lease in a manner that is not accounted for as a separate contract. For leases in which the acquiree was the lessee, the Company will measure the lease liability at the present value of the remaining lease payments, as if the acquired lease were a new lease of the

Company at the acquisition date. The Company will measure the ROU asset at the same amount as the lease liability as adjusted to reflect favorable or unfavorable terms of the lease when compared with market terms. Acquired leasehold improvements will be amortized over the shorter of the useful life of the assets and the remaining lease term at the date of acquisition. However, if the lease transfers ownership of the underlying asset to the lessee, or the lessee is reasonably certain to exercise an option to purchase the underlying asset, the lessee shall amortize the leasehold improvements to the end of their useful life.

The Company’s leases require other payments such as costs related to service components, real estate taxes, common area maintenance, and insurance. These costs are generally variable in nature and based on the actual costs incurred and required by the lease. As the result of the Company’s election to not separate lease and non-lease components, all variable costs associated with the lease are expensed in the period incurred and presented and disclosed as variable lease costs. The Company’s lease agreements do not contain any residual value guarantees or material restrictive financial covenants. The Company does not have any leases that have not yet commenced that create significant rights and obligations for the lessee.

The Company’s leases expire over the next five years and include options that grant the Company the ability to renew or extend the leases, with the renewal options extending the lease for an additional 1 to 10 years, depending on the lease. When determining the lease term, the Company does not include renewal options unless the renewals are deemed to be reasonably certain of being exercised at the lease commencement date.

Topic 842 requires that a lessee use the rate implicit in the lease when measuring the lease liability and ROU asset, unless that rate is not readily determinable. When the rate implicit in the lease is not readily determinable, the Company uses its incremental borrowing rate. The Company’s incremental borrowing rate represents the rate of interest that the Company would have to pay to borrow, on a collateralized basis, an amount equal to the lease payments, over a similar term and in a similar economic environment. The incremental borrowing rate is determined for each lease based on the lease term and the underlying asset, using observable market data and Company specific credit assumptions.

The Company applies an updated incremental borrowing rate for new leases and upon remeasurement events for existing leases.

The Company has included additional disclosures about its operating leases in Note 7.

(o)    Derivatives

The Company uses interest rate-related derivative instruments to manage its exposure related to changes in interest rates on its variable rate debt instruments. All derivative instruments are recognized as either assets or liabilities in the balance sheet at their respective fair values. The Company does not apply hedge accounting to its outstanding interest rate cap and interest rate swap; therefore, changes in the fair values of the derivative instruments are recognized in earnings each reporting period.

(2)    Contingent Consideration

The Company has a contingent consideration arrangement associated with the DST acquisition on December 22, 2022. The contingent consideration arrangement, as evidenced by a seller note, requires the Company to pay the former owner of DST a payout based on the achievement of certain financial metrics of DST during 2023, 2024, and 2025, with a target amount of $15,000,000, as adjusted higher or lower based on the formula in the seller note, to be paid in three installments, the first during 2024, the second during 2025, and the third during 2026. The fair value of the contingent consideration arrangement at the date of acquisition of $9,300,000 and subsequent remeasurement was estimated by applying the income approach. That measure

2025. The First Lien was amended on December 22, 2022, to add an additional term loan in the amount of $40,000,000 and increase the revolving line of credit to $20,000,000. On November 29, 2023, the Company entered into an incremental delayed draw term loan agreement with its lender to provide an additional commitment of $15,000,000.

The First Lien was refinanced on January 23, 2024, representing the Second Amended and Restated Credit Agreement, and included a term loan of $172,500,000 and provided for a $30,000,000 revolving line of credit and a $42,500,000 Delayed Draw Term Loan feature. As part of this refinancing, the Second Lien was paid in full.

On September 9, 2025, the Second Amended and Restated Credit Agreement was further amended to provide for (a) a $200,000,000 term loan, (b) a Delayed Draw Term Loan #1 of $40,000,000, (c) a Delayed Draw Term Loan #2 of $60,000,000 (none of which has been drawn through December 31, 2025) and (d) a $30,000,000 revolving line of credit.

The maturity date of the amended First Lien is the earlier of (a) January 23, 2029, and (b) the date twelve months prior to the maturity date of the Subordinated Term Loan. The revolving line of credit had an outstanding balance of $6,650,000 and $788,098 at December 31, 2025 and 2024, respectively. The revolving line of credit is due on July 23, 2026, and has a variable interest rate, which was 9.25% as of December 31, 2025. Interest related to the revolving line of credit is paid monthly. On January 7, 2026, the First Lien was refinanced with similar terms, but extended its maturity to January 7, 2031. See also Note 12.

On January 8, 2018, Holdco entered into a $37,500,000 subordinated term loan agreement (the Subordinated Term Loan) with an investment firm. The Subordinated Term Loan, as amended on August 3, 2022, bears interest at a variable rate based on an adjusted Secured Overnight Financing Rate (SOFR), plus applicable margin. Interest is due quarterly; however, Holdco may pay up to 10.0% per annum of such interest in kind by capitalizing such portion of the accrued interest into the principal amount of the Subordinated Term Loan. Under certain conditions as set forth in the First and Second Lien Term Loans, the payment of interest on this borrowing would not be permitted. Under these conditions, the entire accrued interest may be treated as in kind and capitalized into the principal amount of the Subordinated Term Loan. The borrowings under this Subordinated Term Loan agreement are subordinate to the First and Second Liens, collateralized by a security interest in Intermediate Holdco and originally were scheduled to mature on January 4, 2024. The agreement was amended on August 3, 2022, to extend the maturity date to January 4, 2026.

As part of the refinancing of the First Lien Term Loan on August 3, 2022, the Company repaid $21,000,000 on this Subordinated Term Loan. Additionally, on December 22, 2022, the Subordinated Term Loan agreement was amended to make additional term loans in the amount of $5,000,000 under the same terms and conditions. On January 23, 2024, the Subordinated Term Loan was amended to extend the maturity date from January 4, 2026 to January 23, 2027. The Subordinated Term Loan was amended again on December 30, 2024, to extend the maturity date from January 23, 2027 to July 23, 2027. On January 7, 2026, the Subordinated Term Loan was refinanced with a different lender and a new maturity date of July 7, 2031. Repayment of the loan principal is due at maturity. See also Note 12. The amount of interest capitalized for the years ended December 31, 2025, 2024 and 2023 was $0, $769,029 and $0, respectively. The amount outstanding was $29,471,221 as of December 31, 2025 and 2024, and the interest rate was 18.09% and 18.65% at December 31, 2025 and 2024, respectively.

On February 16, 2026, the Company and Air Industries Group (AIR) entered into an Agreement and Plan of Merger (the Merger Agreement) to combine the Company’s aviation business with AIR’s aerospace manufacturing business.

The merger is subject to AIR shareholder approval, related regulatory filings, U.S. government approvals and other closing conditions customary for transactions of this size and nature.

(i)          a list of all Tenax Members and Tenax Warrantholders, and each Tenax Member and Tenax Warrantholder’s address; and

(ii)         (A) the portion of the Merger Consideration payable to each Tenax Member and (B) the portion of the Merger Consideration that would be payable to each Tenax Warrantholder if such Tenax Warrantholder had exercised its Warrant (if and to the extent it remains outstanding) immediately prior to the Effective Time (a “Tenax Warrantholder Allocation”), in each case which will (1) be calculated in accordance with the terms and conditions of this Agreement and the limited liability company agreement of Tenax and (2) specifically identify the number of shares of AIR Common Stock payable to each Tenax Member and Tenax Warrantholder; provided that, notwithstanding anything otherwise to the contrary in this Agreement, the aggregate number of shares of AIR Common Stock allocated to the Tenax Members and Tenax Warrantholders shall not exceed the number of shares of AIR Common Stock constituting the Merger Consideration.

(b)         All membership interests of Merger Sub issued and outstanding immediately prior to the Effective Time shall be converted into 100% of the membership interests of the Surviving Company.

Annex A-15

Table of Contents

Section 3.03        Certain Adjustments. Without limiting the obligations of AIR pursuant to Section 6.01, if, at any time on or after the Original Execution Date and prior to the Closing, AIR makes (or any record date occurs with respect thereto) (i) any subdivision, stock dividend or split of any AIR Common Stock (including the AIR Reverse Stock Split) or (ii) combination, recapitalization, exchange of shares, reclassification or similar transaction of AIR Common Stock into a different number of shares of AIR Common Stock or different class, then the Merger Consideration, the Debt Adjusted AIR Share Price and any other amounts payable pursuant to this Agreement shall be appropriately and equitably adjusted to reflect such event and provide the same economic effect for the Tenax Members as contemplated by this Agreement prior to such event.

Section 3.04        Repayment of Payoff Debt. At the Closing, Tenax or one of its Affiliates shall repay, or cause to be repaid, on behalf of AIR and its Subsidiaries, the outstanding balance of the Payoff Debt in accordance with the Payoff Letters furnished to Tenax pursuant to Section 7.13 by wire transfer of immediately available funds to the account designated in the applicable Payoff Letter.

Section 3.05        Reservation of Shares. Prior to the Closing, AIR shall reserve for future issuance upon exercise of the Warrants a number of shares of AIR Common Stock equal to the aggregate amount of the Tenax Warrantholder Allocations set forth on the Tenax Closing Capitalization Schedule.

Section 3.06        Exchange of Shares.

(a)         Transfer Agent. At or prior to the Effective Time, AIR shall deposit, or shall cause to be deposited, with Broadridge Corporate Issuer Solutions, LLC (the “Transfer Agent”), in trust for the benefit of the Tenax Members, a number of shares of AIR Common Stock, in book-entry or certificated form, equal to the portion of the Merger Consideration issuable to the Tenax Members in accordance with the Tenax Closing Capitalization Schedule for the purpose of exchanging Tenax Units for the Merger Consideration.

(b)         Exchange Procedures. Prior to the Effective Time, Tenax will provide to each Person who is or will be, as of immediately prior to the Effective Time, a Tenax Member a letter of transmittal, which shall contain customary representations and warranties of the type commensurate with a private placement of securities exempt from registration under the Securities Act and such other provisions as Tenax may reasonably specify (including a provision confirming that delivery shall be effected, and risk of loss and title shall pass, only upon proper delivery of such letter of transmittal). Upon delivery to the Transfer Agent of such letter of transmittal, duly executed, and such other documents as may reasonably be required by the Transfer Agent or Tenax, the Tenax Member will be entitled to receive (following the Effective Time) in exchange such Tenax Member’s Tenax Units, the portion of the Merger Consideration allocated to such Tenax Member in accordance with the Tenax Closing Capitalization Schedule (together with cash in lieu of fractional shares), and such Tenax Member’s Tenax Units will forthwith be canceled. Until exchanged as contemplated by this Section 3.06, any Tenax Units will be deemed at any time after the Effective Time to represent only the right to receive upon such exchange Merger Consideration as contemplated by this Section 3.06. No interest will be paid or accrue on any cash payable upon exchange of any Tenax Units.

Section 3.07        No Fractional Shares.

(a)         No certificates or scrip representing fractional shares of AIR Common Stock will be issued upon the conversion of Tenax Units pursuant to Section 3.06, and such fractional share interests will not entitle the owner thereof to vote or to any rights of a holder of AIR Common Stock. For purposes of this Section 3.07, all fractional shares to which a single record holder would be entitled will be aggregated, and calculations will be rounded up to three decimal places.

(b)         Fractional shares of AIR Common Stock that would otherwise be allocable to any former Tenax Members in the Merger will be aggregated, and no Tenax Members will receive cash in exchange therefor equal to or greater than the value of one full share of AIR Common Stock. The Transfer Agent will cause the whole shares obtained thereby to be sold, in the open market or otherwise as reasonably directed by AIR, and in no case later than 20 Business Days after the Effective Time (assuming all Tenax Units have been surrendered pursuant to Section 3.05 by such date). The Transfer Agent will make available the net proceeds thereof, after deducting any required withholding Taxes and brokerage charges, commissions and transfer Taxes, on a pro rata basis, without interest, as soon as practicable to the Tenax Members entitled to receive such cash. Payment of cash

Annex A-16

Table of Contents

in lieu of fractional shares of AIR Common Stock will be made solely for the purpose of avoiding the expense and inconvenience to AIR of issuing fractional shares of AIR Common Stock and will not represent separately bargained-for consideration.

Section 3.08        No Liability. None of the parties hereto, the Surviving Company or the Transfer Agent will be liable to any Person in respect of any shares of AIR Common Stock properly delivered to any public official pursuant to any applicable abandoned property, escheat or similar Law.

Section 3.09        Further Action. If, at any time after the Effective Time, any further action is determined by AIR or Tenax to be necessary or desirable to carry out the purposes of this Agreement or to vest the Surviving Company with full right, title and possession, and to all rights and property, of Merger Sub and Tenax, the officers and directors of the Surviving Company and AIR shall be fully authorized (in the name of Merger Sub, in the name of Tenax, and otherwise) to take such action.

Section 3.10        AIR Equity Awards. Each AIR Equity Award that is then outstanding as of immediately prior to the Effective Time shall continue on the same terms and conditions as were applicable to such AIR Equity Award as of immediately prior to the Effective Time. At or prior to the Effective Time, AIR, the AIR Board and the Compensation Committee of the AIR Board, as applicable, shall adopt any resolutions and take any actions which are necessary to effectuate the provisions of this Section 3.10.

ADDITIONAL AGREEMENTS

Section 7.01        AIR Stockholders Meeting; Registration Statement.

(a)         In accordance with the NRS, AIR’s articles of incorporation and bylaws, the Exchange Act and any applicable rules and regulations of NYSE American, AIR, in consultation with Tenax, shall call, give notice of, convene and hold the AIR Stockholders Meeting as promptly as reasonably practicable following the date upon which the Registration Statement has been declared effective under the Securities Act (with the record date and meeting date to be set by the AIR Board after consultation with Tenax regarding such dates) and shall as promptly as reasonably practicable following the date of this Agreement, for the purpose of obtaining the AIR Stockholder Approvals, duly set a record date for determining the stockholders entitled to notice of, and to vote at, the AIR Stockholders Meeting (such date to be at least 20 Business Days following the initiation of a broker search pursuant to Rule 14a-13 under the Exchange Act). Subject to the terms of this Agreement, the AIR Board shall recommend that the stockholders of AIR vote in favor of the approval of the AIR Charter Amendment and the AIR Stock Issuance. AIR shall comply with the NRS, AIR’s articles of incorporation and bylaws, the Exchange Act and the rules and regulations of NYSE American in connection with the AIR Stockholders Meeting, including preparing and delivering the Proxy Statement/Prospectus to AIR’s stockholders, as required pursuant to the Exchange Act and Section 7.01(b) below. Subject to the terms of this Agreement, unless there has been a Change in the AIR Recommendation, AIR shall use its reasonable best efforts to solicit (or cause to be solicited) from its stockholders proxies constituting the AIR Stockholder Approvals. AIR shall not change the date of, postpone or adjourn the AIR Stockholders Meeting without the consent of Tenax (which may not be unreasonably withheld, conditioned or delayed); provided that, without Tenax’s consent, AIR may adjourn or postpone the AIR Stockholders Meeting as may be required by applicable Law and no more than two times (i) to ensure that any required supplement or amendment to the Proxy Statement/Prospectus is provided to AIR’s stockholders within a reasonable amount of time in advance of the AIR Stockholders Meeting, (ii) to allow reasonable additional time to solicit from its stockholders proxies in favor of approval of the AIR Charter Amendment and the AIR Stock Issuance, (iii) if, as of the time for which the AIR Stockholders Meeting is originally scheduled (as set forth in the Proxy Statement/Prospectus) or the time scheduled for reconvening the AIR Stockholders Meeting, there are insufficient shares of AIR Stock represented (either in person or by proxy) to constitute a quorum necessary to conduct the business of the AIR Stockholders Meeting or at such time AIR has not received proxies sufficient to allow the receipt of the AIR Stockholder Approvals at the AIR Stockholders Meeting or (iv) as required by applicable Law; provided further that the AIR Stockholders Meeting shall not be postponed, recessed or adjourned pursuant to this proviso to a date that is more than 30 days after the date on which the AIR Stockholders Meeting was originally scheduled without the prior written consent of Tenax. Tenax may cause AIR to postpone or adjourn the AIR Stockholders Meeting by prior written notice to AIR once for a period of no longer than ten Business Days if at such time AIR has not received proxies sufficient to allow the receipt of the AIR Stockholder Approvals at the AIR Stockholders Meeting and Tenax informs AIR that Tenax believes in good faith that additional time is required to solicit stockholder proxies in favor of approval of the AIR Charter Amendment and the AIR Stock Issuance.

(b)         Promptly following the date of this Agreement, and in any event no later than ten Business Days following the delivery by Tenax of all financial statements that are required by the applicable accounting requirements and other rules and regulations of the SEC to be included in the Registration Statement or the Proxy Statement/Prospectus together with information relating to it required to be included in the Registration Statement or the Proxy Statement/Prospectus under the Exchange Act, the Securities Act or other applicable Law, AIR, with the assistance of Tenax, shall prepare, and AIR shall file with the SEC, the Registration Statement and any amendments or supplements thereto in form and substance reasonably satisfactory to each of AIR and Tenax relating to the Merger and the Transactions. Each of AIR and Tenax shall use its reasonable best efforts to cause the Registration Statement to become effective under the Securities Act as promptly as practicable after such filing and to keep the Registration Statement effective for so long as necessary to consummate the Merger. Subject to the terms of this Agreement, the Proxy Statement/Prospectus shall reflect the AIR Recommendation. Tenax shall, and shall use its reasonable best efforts to cause its Representatives and Affiliates to, cooperate with AIR in the preparation of the Registration Statement and shall furnish to AIR all information relating to it required by the Securities Act and the Exchange Act for inclusion in, or to assist AIR in preparing, the Registration Statement (and responding to any comments from the SEC or its staff with respect thereto), including, without limitation, such financial statements and other information relating to it and its Affiliates required to be included in the Registration Statement under

Annex A-49

the Exchange Act, the Securities Act or other applicable Law. In addition, Tenax shall use its reasonable best efforts to cause its independent accountants to provide assistance and cooperation to AIR in connection with the preparation of the Registration Statement and the Proxy Statement/Prospectus, including, without limitation, to the extent required by applicable Law, providing consent to AIR to include their audit reports in the Registration Statement and providing reasonable assistance in the preparation of pro forma financial statements to be included in the Registration Statement. No filing of, or amendment or supplement to, the Registration Statement or the Proxy Statement/Prospectus will be made by AIR without providing Tenax a reasonable opportunity to review and comment thereon. AIR shall promptly provide Tenax and its counsel with copies of any written comments, and shall inform them of any oral comments, that AIR or its counsel may receive from the SEC or its staff with respect to the Registration Statement or the Proxy Statement/Prospectus, and AIR shall use its reasonable best efforts, after consultation with and with the assistance of Tenax, to respond as promptly as practicable to any such comments of the SEC or its staff and to cause the Registration Statement to be declared effective under the Securities Act and thereafter to cause the Proxy Statement/Prospectus to be mailed to AIR’s stockholders at the earliest practicable time. AIR shall advise Tenax promptly after receiving notice of the issuance of any stop order or the suspension of the qualification of the AIR Common Stock issuable in connection with the Merger for offering or sale in any jurisdiction. Each of AIR and Tenax shall promptly advise the other if it determines that any information provided by it for use in the Registration Statement was or shall have become false or misleading in any material respect and shall promptly notify the other if it becomes aware of any material fact not contained in the Registration Statement and required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading. AIR shall take all steps necessary to cause the Registration Statement as so corrected to be filed with the SEC and the Proxy Statement/Prospectus to be disseminated to holders of shares of AIR Stock, in each case as, and to the extent, required by applicable Law. AIR shall promptly provide Tenax and its counsel with copies of any written comments, and shall inform them of any oral comments, that AIR or its counsel may receive from the SEC or its staff requesting any amendments or supplements to the Registration Statement or the Proxy Statement/Prospectus, and AIR and Tenax shall cooperate in filing with the SEC or its staff, and if required by applicable Law, AIR shall mail to its stockholders, as promptly as reasonably practicable, such amendment or supplement. AIR shall provide Tenax and its counsel a reasonable opportunity to review any written responses to all SEC comments with respect to the Registration Statement or the Proxy Statement/Prospectus, and AIR shall give due consideration to the reasonable additions, deletions or changes suggested thereto by Tenax and its counsel.

Section 7.02        No Solicitation of Transactions.

(a)         AIR agrees that none of it or any of its Subsidiaries or any of their respective Representatives will, and that it will cause each of its Subsidiaries and each of its and its Subsidiaries’ Representatives not to, directly or indirectly, (i) solicit, initiate, seek or take any other action to facilitate or encourage the making, submission or announcement of any proposal that constitutes, or could be reasonably be expected to lead to, any Competing AIR Proposal; (ii) enter into, maintain, continue or participate in any discussions or negotiations with any Person or entity in furtherance of, or furnish to any Person any information or otherwise cooperate in any way with respect to, any Competing AIR Proposal; (iii) agree to, approve, endorse, recommend or consummate any Competing AIR Proposal; (iv) enter into, or propose to enter into, any Competing AIR Transaction Agreement; or (v) resolve, propose or agree, or authorize or permit any Representative, to do any of the foregoing. Without limiting the foregoing, it is agreed that any violation of the restrictions set forth in the preceding sentence by any Representative of AIR or any of its Subsidiaries shall be deemed to be a breach of this Section 7.02(a) by AIR. AIR shall, and shall cause its Subsidiaries and its and its Subsidiaries’ Representatives to, immediately cease and cause to be terminated all existing discussions or negotiations with any Persons conducted prior to the execution of this Agreement by AIR, any of its Subsidiaries or its or any of their respective Representatives with respect to any Competing AIR Proposal, request the prompt return or destruction of all confidential information previously furnished and terminate access to any physical or electronic data rooms related to a potential Competing AIR Proposal previously granted to such Person.

(b)         AIR shall promptly, and in any event within 24 hours of AIR obtaining knowledge of the receipt thereof, advise Tenax orally and in writing of any Competing AIR Proposal or any inquiry relating to or that could reasonably be expected to lead to any Competing AIR Proposal, the financial and other material terms and conditions of any such Competing AIR Proposal or inquiry (including any changes thereto) and the identity of the Person making any such Competing AIR Proposal or inquiry. AIR shall (i) keep Tenax fully informed of the status and material details (including any change to the terms thereof) of any such Competing AIR Proposal or inquiry and (ii) provide to Tenax, as soon as practicable after receipt or delivery thereof (and in any event, within

Annex A-50

Table of Contents

24 hours of such receipt or delivery), unredacted copies of all correspondence (other than non-substantive written correspondence) and other written material (including all draft and final versions (and any amendments thereto) of agreements (including schedules and exhibits thereto) and any comments thereon) relating to any such Competing AIR Proposal or inquiry exchanged between AIR or any of its Subsidiaries (or their Representatives), on the one hand, and the Person making such Competing AIR Proposal or inquiry (or its Representatives), on the other hand.

(c)         Notwithstanding anything to the contrary in this Agreement, at any time prior to the receipt of the AIR Stockholder Approvals, AIR may, subject to compliance with Section 7.02(b), furnish information to, and enter into discussions with, a Person who has made, after the Original Execution Date, an unsolicited, written, bona fide Competing AIR Proposal so long as such Competing AIR Proposal did not result from a breach of this Section 7.02 and, prior to furnishing such information and entering into such discussions, the AIR Board has (i) reasonably determined, in its good-faith judgment (after having received the advice of a financial advisor of nationally recognized reputation and outside legal counsel qualified to practice in the State of Nevada and experienced in matters of Nevada corporate Law) that (A) such Competing AIR Proposal constitutes, or is reasonably likely to lead to, a Superior Proposal and (B) the failure to furnish such information to, or enter into such discussions with, the Person who made such Competing AIR Proposal would violate the AIR Board’s fiduciary duties under the NRS, (ii) previously provided all such information to Tenax (or provides such information to Tenax substantially concurrent with the time it is provided to such Person) and (iii) obtained from such Person an Acceptable AIR Confidentiality Agreement.

(d)         Except as set forth in this Section 7.02(d), neither the AIR Board nor any committee thereof shall (i) (A) fail to make, withdraw, qualify, modify or amend, or propose publicly to fail to make, withdraw, qualify, modify or amend, the AIR Recommendation or fail to include the AIR Recommendation in the Proxy Statement/Prospectus, (B) adopt or recommend, or propose publicly to adopt or recommend, any Competing AIR Proposal or (C) enter into any agreement relating to a Competing AIR Proposal (other than an Acceptable AIR Confidentiality Agreement); or (ii) make any public statement inconsistent with the AIR Recommendation (any of the actions described in the foregoing clauses (i) and (ii), a “Change in the AIR Recommendation”). Notwithstanding the foregoing, if at any time prior to the receipt of the AIR Stockholder Approvals and subject to compliance with Section 7.02(b), in response to the receipt of an unsolicited, written, bona fide Competing AIR Proposal received after the Original Execution Date or the occurrence of an Intervening Event, the AIR Board determines in its good-faith judgment (after having received the advice of a financial advisor of nationally recognized reputation and outside legal counsel qualified to practice in the State of Nevada and experienced in matters of Nevada corporate Law) that the failure of the AIR Board to make a Change in the AIR Recommendation would violate the fiduciary duties of the AIR Board under the NRS, then the AIR Board may make a Change in the AIR Recommendation; provided, however, that no Change in the AIR Recommendation may be made that relates to a Competing AIR Proposal unless such Competing AIR Proposal constitutes a Superior Proposal; provided further that AIR shall not be entitled to exercise its right to make a Change in the AIR Recommendation until after the fifth Business Day following Tenax’s receipt of written notice from AIR advising Tenax that the AIR Board intends to make a Change in the AIR Recommendation (a “Notice of Adverse Recommendation”) and specifying the reasons therefor, including a description of any Intervening Event in reasonable detail or the terms and conditions of any Superior Proposal and including an unredacted copy of any proposed agreement (including schedules and exhibits thereto) relating to such Superior Proposal (it being understood and agreed that any material change regarding such Intervening Event, or any amendment to the financial terms or any other material term of such Superior Proposal, shall require a new Notice of Adverse Recommendation and a new three-Business-Day notice period). AIR agrees that, during the applicable five-Business-Day notice period prior to the AIR Board making a Change in the AIR Recommendation, AIR and its Representatives shall negotiate in good faith with Tenax and its Representatives regarding any revisions to the terms of this Agreement proposed by Tenax. In determining whether to make a Change in the AIR Recommendation, the AIR Board shall take into account any changes to the financial or other terms of this Agreement proposed by Tenax in response to a Notice of Adverse Recommendation or otherwise. At the end of the five-Business-Day notice period (or three-Business-Day notice period with respect to any material change regarding such Intervening Event, or any amendment to the financial terms or any other material term of such Superior Proposal) the AIR Board may effect a Change in the AIR Recommendation if the AIR Board shall again make a determination in good faith after consultation with its outside legal counsel and financial advisors (and taking into account any adjustment or modification of the terms of this Agreement proposed by Tenax), that the Change in the AIR Recommendation is required to comply with the fiduciary duties of the AIR Board under the NRS and, if applicable, the Competing AIR Proposal continues to constitute a Superior Proposal.

Annex A-51

(e)         Notwithstanding anything in this Agreement to the contrary, in no event shall any Change in the AIR Recommendation (A) affect the validity and enforceability of this Agreement or the other Transaction Documents, including the obligations of AIR and AIR’s stockholders that are party to the Transaction Documents to consummate the Merger or the other Transactions or (B) cause any state corporate takeover statute or other similar statute to be applicable to the Merger or the other Transactions.

(f)          Tenax agrees that neither it nor any of its Subsidiaries nor any of their respective Representatives will, and that it will cause each of its Subsidiaries and each of its and its Subsidiaries’ Representatives not to, directly or indirectly, (i) solicit, initiate, seek or take any other action to facilitate or encourage the making, submission or announcement of any proposal that constitutes, or could reasonably be expected to lead to, any Competing Tenax Proposal; (ii) enter into, maintain, continue or participate in any discussions or negotiations with any Person or entity in furtherance of, or furnish to any Person any information or otherwise cooperate in any way with respect to, any Competing Tenax Proposal; (iii) agree to, approve, endorse, recommend or consummate any Competing Tenax Proposal; (iv) enter into, or propose to enter into, any Competing Tenax Transaction Agreement; or (v) resolve, propose or agree, or authorize or permit any Representative, to do any of the foregoing. Without limiting the foregoing, it is agreed that any violation of the restrictions set forth in the preceding sentence by any Representative of Tenax or any of its Subsidiaries shall be deemed to be a breach of this Section 7.02(f) by Tenax. Tenax shall, and shall cause its Subsidiaries and its and its Subsidiaries’ Representatives to, immediately cease and cause to be terminated all existing discussions or negotiations with any Persons conducted prior to the execution of this Agreement by Tenax, any of its Subsidiaries or its or any of their respective Representatives with respect to any Competing Tenax Proposal, request the prompt return or destruction of all confidential information previously furnished and terminate access to any physical or electronic data rooms related to a potential Competing Tenax Proposal previously granted to such Person.

(g)         Tenax shall promptly, and in any event within 24 hours of Tenax obtaining knowledge of the receipt thereof, advise AIR orally and in writing of any Competing Tenax Proposal or any inquiry relating to or that could reasonably be expected to lead to any Competing Tenax Proposal, the financial and other material terms and conditions of any such Competing Tenax Proposal or inquiry (including any changes thereto) and the identity of the Person making any such Competing Tenax Proposal or inquiry. Tenax shall (i) keep AIR fully informed of the status and material details (including any change to the terms thereof) of any such Competing Tenax Proposal or inquiry and (ii) provide to AIR, as soon as practicable after receipt or delivery thereof (and in any event, within 24 hours of such receipt or delivery), unredacted copies of all correspondence (other than non-substantive written correspondence) and other written material (including all draft and final versions (and any amendments thereto) of agreements (including schedules and exhibits thereto) and any comments thereon) relating to any such Competing Tenax Proposal or inquiry exchanged between Tenax or any of its Subsidiaries (or their Representatives), on the one hand, and the Person making such Competing Tenax Proposal or inquiry (or its Representatives), on the other hand.

(h)         Notwithstanding anything to the contrary in this Agreement, at any time prior to the receipt of the AIR Stockholder Approvals, Tenax may, subject to compliance with Section 7.02(g), furnish information to, and enter into discussions with, a Person who has made, after the Original Execution Date, an unsolicited, written, bona fide Competing Tenax Proposal so long as such Competing Tenax Proposal did not result from a breach of this Section 7.02 and, prior to furnishing such information and entering into such discussions, the Tenax Board has obtained from such Person an Acceptable Tenax Confidentiality Agreement.

Section 7.03        Access to Information; Confidentiality.

(a)         Except as otherwise prohibited by applicable Law, from the date of this Agreement until the Effective Time, AIR shall, and shall cause its Subsidiaries to, (i) provide to Tenax and Tenax’s Representatives reasonable access during normal business hours upon reasonable prior notice to the officers, employees and other personnel, agents, properties, offices and other facilities of AIR and its Subsidiaries and to the books and records thereof and (ii) furnish promptly to Tenax such information concerning the business, properties, Contracts, assets, liabilities, personnel and other aspects of AIR and its Subsidiaries as Tenax or its Representatives may reasonably request (including for purposes of conducting regulatory compliance reviews and audits to allow Tenax to be in compliance with its policies and procedures and any applicable Law at the Effective Time); provided, however, that AIR shall not be required to provide access to or disclose any such information to the extent such access or disclosure would result in the loss of attorney-client privilege of AIR or any of its Subsidiaries (provided that AIR and its Subsidiaries shall use their reasonable best efforts to allow for such access or disclosure in a manner that does not result in a loss of attorney-client privilege).

Annex A-52

(c)         All information obtained by the parties hereto pursuant to this Section 7.03 shall be kept confidential in accordance with the Confidentiality Agreement.

(d)         No investigation pursuant to this Section 7.03 shall affect any representation, warranty, covenant or agreement in this Agreement of any party hereto or any condition to the obligations of the parties hereto.

Section 7.04        Employee Benefits Matters.

(a)         For the period beginning on the Closing Date and continuing through the first anniversary of the Closing Date (or, if shorter, during the period of employment), AIR shall, or shall cause its Subsidiaries to, provide each employee of AIR or its Subsidiaries, as of immediately prior to the Effective Time, who continues to be employed by AIR or the Surviving Company after the Closing Date (collectively, the “Continuing Employees”) with (i) a base salary or wage rate, as applicable, and annual cash target bonus opportunity that is not less than the base salary or wage rate, as applicable, and annual target cash bonus opportunity provided to such Continuing Employee immediately prior to the Effective Time and (ii) other employee benefits (including severance benefits) that are no less favorable in the aggregate than either, as determined by AIR in its sole discretion, (A) the other employee benefits provided to such Continuing Employee by AIR and its Subsidiaries immediately prior to the Effective Time or (B) the other employee benefits provided to similarly situated employees of Tenax and its Subsidiaries immediately prior to the Effective Time. Notwithstanding anything herein to the contrary, effective from and after the Closing Date, the terms and conditions of employment for any Continuing Employee covered by an AIR Collective Bargaining Agreement shall continue to be governed by the applicable AIR Collective Bargaining Agreement until the expiration, modification or termination of such AIR Collective Bargaining Agreement in accordance with its terms or applicable Laws.

(b)         Without limiting the generality of Section 10.05, the provisions of this Section 7.04 are for the sole benefit of the parties to this Agreement and nothing herein, express or implied, is intended or shall be construed to confer upon or give any Person (including, for the avoidance of doubt, any Continuing Employee or other current or former AIR Service Provider or Tenax Service Provider), other than the parties hereto and their respective permitted successors and assigns, any legal or equitable or other rights or remedies (including with respect to the matters provided for in this Section 7.04) under or by reason of any provision of this Agreement.

For the avoidance of doubt, the applicable rights of indemnification and exculpation contemplated by this Section 7.05 and pursuant to the terms of the articles of incorporation or bylaws of AIR as in effect at or prior to the Effective Time shall not be impaired by any modification of such terms in any amendment or restatement of such articles of incorporation or bylaws following the Effective Time.

Annex A-53

(b)         For the three-year period commencing immediately after the Effective Time, AIR shall maintain in effect a directors’ and officers’ liability insurance with an insurance carrier with the same or better credit rating as AIR’s insurance carrier as of the date hereof covering acts or omissions occurring at or prior to the Effective Time with respect to those individuals who are currently (and any additional individuals who prior to the Effective Time become) covered by AIR’s directors’ and officers’ liability insurance policies on terms, conditions, retentions and limits of liability that are at least as favorable as AIR’s existing policies in effect on the date of this Agreement. AIR shall be permitted, prior to the Effective Time, to obtain and fully pay the premium, subject to the maximum annual premium referred to in the first proviso to this Section 7.05(b), for the extension of (i) the directors’ and officers’ liability coverage of AIR’s existing directors’ and officers’ insurance policies and (ii) AIR’s existing fiduciary liability insurance policies, in each case, for a claims reporting or discovery period of three years from and after the Effective Time that shall be from an insurance carrier with the same or better credit rating as AIR’s insurance carrier as of the date hereof with respect to directors’ and officers’ liability insurance and fiduciary liability insurance (collectively, “D&O Insurance”) with terms, conditions, retentions and limits of liability that are at least as favorable as AIR’s existing policies with respect to matters existing or occurring at or prior to the Effective Time (including in connection with this Agreement, the Merger or the other Transactions). Notwithstanding anything to the contrary contained herein, in no event shall Tenax or AIR after the Effective Time be required to expend for any policies contemplated by this clause (b) an annual premium amount in excess of 300% of the annual premiums currently paid by AIR for such insurance; provided further that if the annual premiums of such insurance coverage exceed such amount, after the Effective Time, AIR shall obtain a policy with the greatest coverage available for a cost not exceeding such amount. If such prepaid D&O Insurance has been obtained by AIR prior to the Effective Time, it shall be deemed to satisfy all obligations to obtain insurance pursuant to this Section 7.05(b), and AIR shall use its reasonable best efforts to cause such D&O Insurance to be maintained in full force and effect, for its full term, and to honor all of its obligations thereunder.

(e)         All Expenses incurred in connection with this Agreement and the Transactions shall be paid by the party incurring such Expenses, whether or not the Merger or any other Transaction is consummated, except Expenses constituting the out-of-pocket cost of (i) filing fees, printing and mailing of the Registration Statement and the Proxy Statement/Prospectus (excluding, for the avoidance of doubt, the fees and expenses of AIR’s legal counsel) and (ii) the filing fees for the premerger notification and report forms under the HSR Act (excluding, for the avoidance of doubt, the fees and expenses of AIR’s legal counsel), which, in each case, shall be paid by Tenax.

(f)          The parties hereto acknowledge and agree that the agreements contained in Section 9.03(a) are an integral part of the Transactions, and that, without these agreements, the parties hereto would not enter into this Agreement; accordingly, if AIR fails promptly to pay the AIR Termination Fee, and, in order to obtain such payment, Tenax commences a suit that results in a judgment against AIR for the AIR Termination Fee, AIR shall pay to Tenax its costs and expenses (including attorneys’ fees and expenses) in connection with such suit, up to $500,000, together with interest on the amount of the AIR Termination Fee from the date such payment was required to be made until the date of payment at the prime rate set forth in The Wall Street Journal in effect on the date such payment was required to be made. Each party further acknowledges that the AIR Termination Fee is not a penalty, but rather is a reasonable amount that will compensate the receiving party in the circumstances in which such payment is payable for the efforts and resources expended and opportunities forgone while negotiating this Agreement and in reliance on this Agreement and on the expectation of the consummation of the Transactions contemplated hereby, which amounts would otherwise be impossible to calculate with precision.

(g)         The parties hereto acknowledge and agree that the agreements contained in Section 9.03(b) are an integral part of the Transactions, and that, without these agreements, the parties hereto would not enter into this Agreement; accordingly, if Tenax fails promptly to pay the Tenax Termination Fee, and, in order to obtain such payment, AIR commences a suit that results in a judgment against Tenax for the Tenax Termination Fee, Tenax shall pay to AIR its costs and expenses (including attorneys’ fees and expenses) in connection with such suit, up to $500,000, together with interest on the amount of the Tenax Termination Fee from the date such payment was required to be made until the date of payment at the prime rate set forth in The Wall Street Journal in effect on the date such payment was required to be made. Each party further acknowledges that the Tenax Termination Fee is not a penalty, but rather is a reasonable amount that will compensate the receiving party in the circumstances in which such payment is payable for the efforts and resources expended and opportunities forgone while negotiating this Agreement and in reliance on this Agreement and on the expectation of the consummation of the Transactions contemplated hereby, which amounts would otherwise be impossible to calculate with precision.

(h)         In the event the AIR Termination Fee is required to be paid and is paid to Tenax pursuant to Section 9.03(a), such payment of the AIR Termination Fee shall constitute liquidated damages and be the sole and exclusive monetary remedy of Tenax and its Subsidiaries and Tenax’s and its Subsidiaries’ respective current, former or future equityholders, employees, directors, officers, Affiliates or Representatives (collectively, the “Tenax Related Parties”) against AIR and Merger Sub and their respective current, former or future equityholders, employees, directors, officers, Affiliates or Representatives (collectively, the “AIR Related Parties”) for all losses, damages, costs or expenses in respect of this Agreement (or the termination thereof) or the Transactions (or the failure of such transactions to occur for any reason or for no reason) or any breach (whether willful, intentional, unilateral or otherwise) of any covenant or agreement or otherwise in respect of this Agreement or any oral representation made or alleged to be made in connection herewith, and upon payment of the AIR Termination Fee, none of the AIR Related Parties shall have any further monetary liability or obligation relating to or arising out of this Agreement or the Transactions, and none of Tenax, its Subsidiaries or any other Tenax Related Party shall seek to recover any other monetary damages.

(i)          In the event the Tenax Termination Fee is required to be paid and is paid to AIR pursuant to Section 9.03(b), such payment of the Tenax Termination Fee shall constitute liquidated damages and be the sole and exclusive monetary remedy of the AIR Related Parties against the Tenax Related Parties for all losses, damages, costs or expenses in respect of this Agreement (or the termination thereof) or the Transactions (or the failure of

such transactions to occur for any reason or for no reason) or any breach (whether willful, intentional, unilateral or otherwise) of any covenant or agreement or otherwise in respect of this Agreement or any oral representation made or alleged to be made in connection herewith, and upon payment of the Tenax Termination Fee, none of the Tenax Related Parties shall have any further monetary liability or obligation relating to or arising out of this Agreement or the Transactions, and none of AIR, its Subsidiaries or any other AIR Related Party shall seek to recover any other monetary damages.

Section 9.04        Amendment. This Agreement may be amended by the parties hereto by action taken by or on behalf of the Tenax Board, the AIR Board and the Board of Directors of Merger Sub at any time prior to the Effective Time; provided, however, that, after the AIR Stockholder Approvals have been obtained, no amendment may be made that under applicable Law or in accordance with the rules of any relevant stock exchange requires further approval by the stockholders of AIR without such approval having been obtained. This Agreement may not be amended except by an instrument in writing signed by each of the parties hereto.

Section 9.05        Waiver. At any time prior to the Effective Time, any party hereto may (a) extend the time for the performance of any obligation or other act of any other party hereto, (b) to the extent permitted by applicable Law, waive any breach of or inaccuracy in the representations and warranties of any other party contained in this Agreement or in any document delivered pursuant hereto and (c) to the extent permitted by applicable Law, waive compliance with any agreement of any other party or any condition to its own obligations contained in this Agreement. No extension or waiver by AIR shall require the approval of the stockholders of AIR, unless required by applicable Law. Notwithstanding the foregoing, no failure or delay by Tenax or AIR or Merger Sub in exercising any right hereunder shall operate as a waiver thereof, nor shall any single or partial exercise thereof preclude any other or future exercise of any other right hereunder. Any such extension or waiver shall be valid if set forth in an instrument in writing signed by the party or parties to be bound thereby.

Section 9.06        Procedure for Termination or Amendment. A termination of this Agreement pursuant to Section 9.01 or an amendment of this Agreement pursuant to Section 9.04 shall, in order to be effective, require, in the case of Tenax or AIR, action by the Tenax Board or the AIR Board or, with respect to any amendment of this Agreement pursuant to Section 9.04, the duly authorized committee of the Tenax Board or the AIR Board to the extent permitted by applicable Law.

Section 10.07      Specific Performance. The parties hereto agree that the parties hereto would be irreparably damaged if any provision of this Agreement was not performed in accordance with its specific terms or was otherwise breached.

WHEREAS, Tenax, AIR and Transitory Air Sub LLC, a Delaware limited liability company and wholly owned subsidiary of AIR, have entered into an Agreement and Plan of Merger dated as of February 16, 2026 (as it may be amended from time to time, the “Merger Agreement”), which provides for, among other things, the merger of Merger Sub with and into Tenax, with Tenax continuing as the surviving limited liability company in the merger (the “Merger”);

(b) “Covered Shares” means, with respect to any Supporting Stockholder, (i) all shares of AIR Stock set forth opposite such Supporting Stockholder’s name on Schedule 1(b) attached hereto and (ii) all shares of AIR Stock that such Supporting Stockholder comes to Beneficially Own during the period from the date of this Agreement through the Expiration Date, together with any voting securities or instruments of AIR, or other securities or interests exercisable for or convertible into shares of AIR Stock or voting securities or instruments of AIR, that such Supporting Stockholder comes to Beneficially Own during the period from the date of this Agreement through the Expiration Date (including by way of bonus issue, share dividend or distribution, subdivision, reclassification, recapitalization, consolidation, exchange, readjustment or other similar transaction or other change in the capital structure of AIR).

9. Irrevocable Proxy.

(a) Each Supporting Stockholder hereby irrevocably grants to, and appoints, Tenax, and any individual designated in writing by Tenax, and each of them individually, as such Supporting Stockholder’s proxy and attorney-in-fact (with full power of substitution), for and in the name, place and stead of such Supporting Stockholder, to vote such Supporting Stockholder’s Covered Shares, or execute a written consent or grant approval in respect of such Covered Shares, in a manner consistent with this Agreement from the date hereof until the Expiration Date; provided, however, for the avoidance of doubt, that such proxy and voting and related rights are limited to those matters set forth in clauses (a) and (b) of Section 3, and each Supporting Stockholder shall retain at all times the right to vote such Supporting Stockholder’s Covered Shares (or to direct how such Covered Shares shall be voted) in such Supporting Stockholder’s sole discretion and without any other limitation on any matters not connected with the Transactions.

Each Supporting Stockholder hereby affirms that the irrevocable proxy set forth in this Section 9(a) is given to secure the performance of the duties of such Supporting Stockholder under this Agreement. Each Supporting Stockholder hereby further affirms that the irrevocable proxy is coupled with an interest sufficient in law and such irrevocable proxy is executed and intended to be irrevocable in accordance with applicable Law and AIR’s bylaws until, and shall not be terminated by operation of Law or upon the occurrence of any other event other than, the termination of this Agreement pursuant to Section 16.

(g) Severability.

(f)  Parties in Interest; No Third Party Beneficiaries. This Agreement shall be binding upon, inure solely to the benefit of and be enforceable by only the parties hereto, and nothing in this Agreement, express or implied, is intended to or shall confer upon any other Person any right, benefit or remedy of any nature whatsoever under or by reason of this Agreement.

(g)  Severability. If any term or other provision of this Agreement is invalid, illegal or incapable of being enforced by virtue of any rule of Law or public policy, all other conditions and provisions of this Agreement shall nevertheless remain in full force and effect so long as the economic or legal substance of the transactions contemplated hereby is not affected in any manner materially adverse to any party. Upon such determination that any term or other provision is invalid, illegal or incapable of being enforced, the parties hereto shall negotiate in good faith to modify this Agreement so as to effect the original intent of the parties as closely as possible in a mutually acceptable manner in order that the transactions contemplated hereby be consummated as originally contemplated to the fullest extent possible.

(h)  Interpretation.

(i)  Whenever the words “include”, “includes” or “including” are used in this Agreement, they shall be deemed to be followed by the words “without limitation”.

When reference is made to a Section or Schedule, such reference is to a Section of, or Schedule to, this Agreement unless otherwise indicated. The descriptive headings contained in this Agreement are included for convenience of reference only and shall not affect in any way the meaning or interpretation of this Agreement. All terms defined in this Agreement shall have the defined meanings when used in any certificate or other document made or delivered pursuant hereto, unless otherwise defined therein. The words “hereof”, “herein” and “hereunder” and words of similar import, when used in this Agreement, refer to this Agreement as a whole and not to any particular provision of this Agreement. The word “or” is not exclusive (i.e., it means “and/or”). Any Contract, instrument or Law defined or referred to herein or in any Contract or instrument that is referred to herein means such Contract, instrument or Law as from time to time amended, modified or supplemented, including (in the case of Contracts or instruments) by waiver or consent and (in the case of Laws) by succession of comparable successor Laws and references to all attachments thereto and instruments incorporated therein. References to a Person are also to its permitted successors and assigns.

(ii)  Each of the parties has participated in the drafting and negotiation of this Agreement. If an ambiguity or question of intent or interpretation arises, this Agreement must be construed as if it is drafted by all the parties, and no presumption or burden of proof shall arise favoring or disfavoring any party by virtue of authorship of any of the provisions of this Agreement.

(i)  Assignment. Neither this Agreement nor any of the rights, interests or obligations hereunder shall be assigned by any of the parties, in whole or in part (whether pursuant to a merger, by operation of Law or otherwise), without the prior written consent of the other parties.

The parties further agree that no party shall be required to obtain, furnish or post any bond or similar instrument in connection with or as a condition to obtaining any such legal or equitable relief, and each party waives any objection to the imposition of such relief or any right it might have to require the obtaining, furnishing or posting of any such bond or similar instrument.

CONFIDENTIAL

TENAX MEMBER LOCK-UP AGREEMENT

February 16, 2026

Air Industries Group

1460 Fifth Avenue

Bay Shore, New York 11706

Ladies and Gentlemen:

The undersigned signatory of this lock-up agreement (this “Letter Agreement”) understands that Air Industries Group (“AIR”), has entered into an Agreement and Plan of Merger, dated as of February 16, 2026 (as the same may be amended, restated or otherwise modified from time to time from time to time, the “Merger Agreement”), with Tenax Aerospace Acquisition, LLC, a Delaware limited liability company, and Transitory Air Sub LLC, a Delaware limited liability company. Capitalized terms used herein and not otherwise defined shall have the meanings set forth in the Merger Agreement.

As a condition and inducement to the parties entering into the Merger Agreement and consummating the Transactions, and for other good and valuable consideration, the receipt and sufficiency of which is hereby acknowledged, the undersigned hereby irrevocably agrees that, subject to the exceptions set forth herein, without the prior written consent of AIR, the undersigned will not, during the period commencing upon the Closing and ending on the date that is 180 days after the Closing Date (such period, the “Restricted Period”), (1) offer, pledge, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant to purchase, lend, or otherwise transfer or dispose of, directly or indirectly, any shares of common stock, $0.001 per share par value, of AIR (“AIR Common Stock”) or any securities convertible into or exercisable or exchangeable for AIR Common Stock (including without limitation, AIR Common Stock or such other securities which may be deemed to be beneficially owned by the undersigned in accordance with the rules and regulations of the Securities and Exchange Commission and securities which may be issued upon exercise of a stock option or warrant) (collectively with AIR Common Stock, “Lock-Up Securities”), (2) enter into any hedging, swap or other agreement or transaction that transfers, in whole or in part, any of the economic consequences of ownership of the Lock-Up Securities, whether any such transaction described in clause (1) or (2) above is to be settled by delivery of Lock-Up Securities, in cash or otherwise, (3) make any demand for or exercise any right with respect to the registration of any Lock-Up Securities or (4) publicly disclose the intention to do any of the foregoing. The undersigned acknowledges and agrees that the foregoing precludes the undersigned from engaging in any hedging or other transactions or arrangements (including, without limitation, any short sale or the purchase or sale of, or entry into, any put or call option, or combination thereof, forward, swap or any other derivative transaction or instrument, however described or defined) designed or intended, or which could reasonably be expected to lead to or result in, a sale or disposition or transfer (whether by the undersigned or any other person) of any economic consequences of ownership, in whole or in part, directly or indirectly, of any Lock-Up Securities, whether any such transaction or arrangement (or instrument provided for thereunder) would be settled by delivery of Lock-Up Securities, in cash or otherwise.

Notwithstanding the foregoing, the undersigned may:

(a) transfer the undersigned’s Lock-Up Securities:

(i) as a bona fide gift or gifts, or for bona fide estate planning purposes, including to charitable organizations,

(ii) by will or intestacy,

(iii) to any trust for the direct or indirect benefit of the undersigned or the immediate family of the undersigned, or if the undersigned is a trust, to a trustor or beneficiary of the trust or to the estate of a beneficiary of such trust (for purposes of this Letter Agreement, “immediate family” shall mean any relationship by blood, current or former marriage, domestic partnership or adoption, not more remote than first cousin),

Annex A-97

Table of Contents

(iv) to a partnership, limited liability company or other entity of which the undersigned and the immediate family of the undersigned are the legal and beneficial owner of all of the outstanding equity securities or similar interests,

(v) to a nominee or custodian of a person or entity to whom a disposition or transfer would be permissible under clauses (i) through (iv) above,

(vi) if the undersigned is a corporation, partnership, limited liability company, trust or other business entity, (A) to another corporation, partnership, limited liability company, trust or other business entity that is an affiliate (as defined in Rule 405 promulgated under the Securities Act of 1933, as amended) of the undersigned, or to any investment fund or other entity controlling, controlled by, managing or managed by or under common control with the undersigned or affiliates of the undersigned (including, for the avoidance of doubt, where the undersigned is a partnership, to its general partner or a successor partnership or fund, or any other funds managed by such partnership), or (B) as part of a distribution to members or shareholders of the undersigned,

(vii) by operation of law, such as pursuant to a qualified domestic order, divorce settlement, divorce decree separation agreement or an order of a regulatory agency,

(viii) to AIR from an employee of AIR or any of its Subsidiaries upon death, disability or termination of employment, in each case, of such employee,

(ix) as part of a sale of the undersigned’s Lock-Up Securities acquired in open market transactions after the Closing,

(x) to AIR in connection with the vesting, settlement or exercise of restricted stock units, options, warrants or other rights to purchase shares of AIR Common Stock (including, in each case, by way of “net” or “cashless” exercise), including for the payment of exercise price and tax and remittance payments due as a result of the vesting, settlement or exercise of such restricted stock units, options, warrants or other rights; provided that any such shares of AIR Common Stock received upon such exercise, vesting or settlement shall be subject to the terms of this Letter Agreement; provided further that any such restricted stock units, options, warrants or other rights are held by the undersigned pursuant to an agreement or equity awards granted under a stock incentive plan or other equity award plan,

(xi) pursuant to a bona fide third-party tender offer, merger, consolidation or other similar transaction that is approved by the Board of Directors of AIR and made to all holders of the AIR’s capital stock involving a Change of Control (as defined below) of AIR (for purposes hereof, “Change of Control” shall mean the transfer (whether by tender offer, merger, consolidation or other similar transaction), in one transaction or a series of related transactions, to a person or group of affiliated persons, of shares of capital stock if, after such transfer, such person or group of affiliated persons would hold at least a majority of the outstanding voting securities of AIR (or the surviving entity)); provided that in the event that such tender offer, merger, consolidation or other similar transaction is not completed, the undersigned’s Lock-Up Securities shall remain subject to the provisions of this Letter Agreement; and

(xii) (A) pursuant to a pledge or hypothecation of any Lock-Up Securities to a nationally recognized bank experienced in margin lending (a “Collateral Pledgee”) for purposes of collateralizing a margin loan, or any entry into a contract, option or other arrangement or understanding with respect thereto; (B) in which any Collateral Pledgee exercises its rights to foreclose upon and take ownership of any Lock-Up Securities pledged to it; or (C) in which such Collateral Pledgee transfers any Lock-Up Securities that such Collateral Pledgee took ownership of in connection with exercise of such Collateral Pledgee’s rights of foreclosure;

provided that (A) in the case of any transfer or distribution pursuant to clause (a)(i), (ii), (iii), (iv), (v), (vi) and (vii), such transfer shall not involve a disposition for value and each donee, devisee, transferee or distributee shall execute and deliver to AIR a lock-up letter in the form of this Letter Agreement, (B) in the case of any transfer or distribution pursuant to clause (a), no filing by any party (donor, donee, devisee, transferor, transferee, distributer or distributee) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), or other public announcement shall be required or shall be made voluntarily in connection with such transfer or distribution (other than a filing on a Form 5 made after the expiration of the Restricted Period referred to above) and (C) in the case of any transfer or distribution pursuant to clause (a)(vii) and (viii), it shall be a condition to such transfer that no public filing, report or

Annex A-98

Table of Contents

announcement shall be voluntarily made, and if any filing under Section 16(a) of the Exchange Act or other public filing, report or announcement reporting a reduction in beneficial ownership of shares of AIR Common Stock in connection with such transfer or distribution shall be legally required during the Restricted Period, such filing, report or announcement shall clearly indicate in the footnotes thereto the nature and conditions of such transfer;

(b) exercise outstanding options, settle restricted stock units or other equity awards or exercise warrants pursuant to plans of AIR; provided that any Lock-Up Securities received upon such exercise, vesting or settlement shall be subject to the terms of this Letter Agreement;

(c) convert outstanding preferred stock, warrants to acquire preferred stock or convertible securities into shares of AIR Common Stock or warrants to acquire shares of AIR Common Stock; provided that any such shares of AIR Common Stock or warrants received upon such conversion shall be subject to the terms of this Letter Agreement; and

(d) establish trading plans pursuant to Rule 10b5-1 under the Exchange Act for the transfer of shares of Lock-Up Securities; provided that (1) such plans do not provide for the transfer of Lock-Up Securities during the Restricted Period, other than filings required under the Exchange Act, and (2) no filing by any party under the Exchange Act or other public announcement shall be required or made voluntarily in connection with such trading plan.

In furtherance of the foregoing, AIR, and any duly appointed transfer agent for the registration or transfer of the securities described herein, are hereby authorized to decline to make any transfer of securities if such transfer would constitute a violation or breach of this Letter Agreement.

The undersigned hereby represents and warrants that the undersigned has full power and authority to enter into this Letter Agreement. All authority herein conferred or agreed to be conferred and any obligations of the undersigned shall be binding upon the successors, assigns, heirs or personal representatives of the undersigned.

Any and all remedies herein expressly conferred upon AIR will be deemed cumulative with and not exclusive of any other remedy conferred hereby, or by Law or equity, and the exercise by AIR of any one remedy will not preclude the exercise of any other remedy. The undersigned agrees that irreparable damage would occur to AIR in the event that any provision of this Letter Agreement were not performed in accordance with its specific terms or were otherwise breached. It is accordingly agreed that AIR shall be entitled to an injunction or injunctions to prevent breaches of this Letter Agreement and to enforce specifically the terms and provisions hereof in any court of the United States or any state having jurisdiction, this being in addition to any other remedy to which AIR is entitled at Law or in equity, and the undersigned waives any bond, surety or other security that might be required of AIR with respect thereto.

This Letter Agreement may be executed in several counterparts, each of which shall be deemed an original and all of which shall constitute one and the same instrument. The exchange of a fully executed Letter Agreement (in counterparts or otherwise) by AIR and the undersigned by facsimile or electronic transmission in .pdf format shall be sufficient to bind such parties to the terms and conditions of this Letter Agreement.

This Letter Agreement and any claim, controversy or dispute arising under or related to this Letter Agreement shall be governed by and construed in accordance with the laws of the State of Nevada. This Letter Agreement shall automatically terminate and cease to be of further force and effect upon the valid termination of the Merger Agreement.

THIRD AMENDED AND RESTATED

LIMITED LIABILITY COMPANY AGREEMENT

OF

TENAX AEROSPACE ACQUISITION, LLC

This Third Amended and Restated Limited Liability Company Agreement (the “Agreement”) of Tenax Aerospace Acquisition, LLC (the “Company”) is entered into by Air Industries Group, a Nevada Corporation (the “Member”), and amends and restates in its entirety the Second Amended and Restated Limited Liability Company Agreement of the Company, effective as of January 7, 2026 (the “Original Agreement”).

(the “Act”).

Accordingly, the Member hereby agrees to amend and restate the Original Agreement as follows:

1. Name; Formation. The name of the Company shall be Tenax Aerospace Acquisition, LLC, or such other name as the Member may from time to time hereafter designate through filing an appropriate name amendment with the Secretary of State of the State of Delaware.

2. Purpose. The purpose of the Company shall be to engage in any lawful business that may be engaged in by a limited liability company organized under the Act, as such business activities may be determined by the Member from time to time.

3. Registered Agent and Office. The registered agent for service of process is, and the mailing address for the registered office of the Company in the State of Delaware is in care of: Corporation Trust Center, 1209 Orange Street, in the City of Wilmington, County of New Castle, Delaware 19801. Such agent and such office may be changed from time to time by the Member.

4. Term. The term of the Company shall continue perpetually unless the Company is dissolved pursuant to Section 8.

5. Member. The Member shall own all limited liability company interests in the Company and shall be the sole member of the Company. The business address of the Member of the Company is set forth on Schedule I attached hereto, as the same may be amended from time to time.

6. Management of the Company.

A. The Company shall be member-managed by the Member. The Member shall have the sole right to manage the business of the Company and shall have all powers and rights necessary, appropriate or advisable to effectuate and carry out the purposes and business of the Company.

B. The Member may appoint a President, Chief Executive Officer, Chief Financial Officer, Senior Vice President, Vice Presidents, Secretary, Treasurer, Assistant Secretary and Assistant Treasurer (the persons appointed to such positions from time to time, the “Officers”) and/or such other management personnel to such terms and to perform such functions as the Member shall determine in its discretion. The Member may appoint, employ or otherwise contract with such other persons or entities for the transaction of the business of the Company or the performance of services for or on behalf of the Company as it shall determine in its discretion. The Member may delegate to any such Officer, person or entity such authority to act on behalf of the Company as the Member may from time to time deem appropriate in its discretion.

Table of Contents

C. When the taking of such action has been authorized by the Member, any Officer of the Company or any other person specifically authorized by the Member may execute any contract or other agreement or document on behalf of the Company and may execute and file on behalf of the Company with the Secretary of State of the State of Delaware any certificates of amendment to the Certificate, one or more restated certificates of formation and certificates of merger or consolidation and, upon the dissolution and completion of winding up of the Company or as otherwise provided in the Act, a certificate of cancellation canceling the Certificate.

8. Dissolution. The Company shall be dissolved and its affairs wound up and terminated upon the first to occur of the following:

A. the determination of the Member to dissolve the Company; or

B. the occurrence of any event causing a dissolution of the Company under the Act.

9. Limitation on Liability. The debts, obligations and liabilities of the Company, whether arising in contract, tort or otherwise, shall be solely the debts, obligations and liabilities of the Company, and the Member shall not be obligated personally for any such debt, obligation or liability of the Company solely by reason of being the Member. The failure of a limited liability company to observe any formalities or requirements relating to the exercise of its powers or management of its business or affairs under this Agreement or the Act shall not be grounds for imposing personal liability on the Member for liabilities of the limited liability company.

10. Corporate Opportunities. The Company waives any and all requirements that the Member bring all investment or business opportunities to the Company of which the Member becomes aware and which are competitive with the business. The Company and the Member agree that the Member may pursue or consummate (directly or indirectly) any such opportunities. This Section 10 shall not in any way affect, limit or modify any liabilities, obligations, duties or responsibilities of any person or entity under any employment agreement, consulting agreement, confidentiality agreement, noncompete agreement, nonsolicit agreement or any similar agreement with the Company.

11. Limitation of Duties; Conflict of Interest. Notwithstanding anything in this Agreement to the contrary, the Member shall not have any duty (including fiduciary duty), or any liability for a breach of duty (including fiduciary duty), to the Company; provided that the foregoing shall not limit or eliminate liability for any act or omission that constitutes a bad faith violation of any applicable implied contractual covenant of good faith and fair dealing.

12. Indemnification.

A. General Rule. To the fullest extent permitted by law, the Company shall indemnify an “indemnified representative” (as defined below) against any liability incurred in connection with any proceeding in which the indemnified representative may be involved as a party or otherwise by reason of the fact that such person is or was serving in an “indemnified capacity” (as defined below), including liabilities resulting from any actual or alleged breach or neglect of duty, error, misstatement or misleading statement or act giving rise to strict products liability; provided, however, that any indemnity under this Section 12 shall be provided out of and to the extent of the Company’s assets only, and the Member shall not have any personal liability on account thereof; provided further that no indemnity shall be payable hereunder against any liability incurred by such indemnified representative by reason of any action or omission that constitutes fraud, willful misconduct or gross negligence or for which a corporation, incorporated under the General Corporations Law of the State of Delaware, would

Annex A-104

Table of Contents

not be permitted under applicable law to indemnify. If an indemnified representative is entitled to indemnification in respect of a portion, but not all, of any liabilities to which such indemnified representative may be subject, the Company shall indemnify such indemnified representative to the maximum extent legally permissible for such liabilities. The termination of a proceeding by judgment, order, settlement or conviction or upon a plea of nolo contendere or its equivalent shall not of itself create a presumption that the indemnified representative is not entitled to indemnification under this Section 12.

B. Definitions. For purposes of this Section 12:

                    i.            indemnified capacity” means any and all past, present and future actions or inactions by an indemnified representative in one or more capacities as a member, manager, director, observer, officer or agent of the Company, or, at the request of the Company, as a member, manager, director, officer, employee, agent, fiduciary or trustee of another limited liability company, corporation, partnership, joint venture, trust, employee benefit plan or other entity or enterprise;

                    ii.           indemnified representative” means the Member, any and all other members (and any and all officers, directors and employees of the Member or such other members), managers and officers of the Company, and any other person designated as an indemnified representative by a member (which may, but need not, include any person serving, at the request of the Company, as a member, manager, officer, employee, agent, fiduciary or trustee of another limited liability company, corporation, partnership, joint venture, trust, employee benefit plan or other entity or enterprise)

                    iii.          liability” means any damage, judgment, amount paid in settlement, fine, penalty, punitive damages, excise tax assessed with respect to any employee benefit plan or cost or expense of any nature (including attorneys’ fees and disbursements)

                    iv.          proceeding” means any threatened, pending or completed action, suit, appeal or other proceeding of any nature, whether civil, criminal, administrative or investigative, whether formal or informal, and whether brought by or in the right of the Company, the Member or otherwise.

C. Advancing Expenses. To the fullest extent permitted by law, the Company may pay the expenses (including attorneys’ fees and disbursements) incurred in good faith by an indemnified representative in advance of the final disposition of a proceeding upon receipt of an undertaking by or on behalf of the indemnified representative to repay the amount if it is ultimately determined that such person is not entitled to be indemnified by the Company pursuant to this Section 12.

D. Securing of Indemnification Obligations. To further effect, satisfy or secure the indemnification obligations provided in this Section 12 or otherwise, the Company may maintain insurance, obtain a letter of credit, act as self-insurer, create a reserve, trust, escrow, cash collateral or other fund or account, enter into indemnification agreements, pledge or grant a security interest in any assets or properties of the Company or use any other mechanism or arrangement whatsoever in such amounts, at such costs and upon such other terms and conditions as the Member shall deem appropriate.

E. Scope of Section. The rights granted by this Section 12 shall not be deemed exclusive of any other rights to which those seeking indemnification, contribution or advancement of expenses may be entitled under any statute, agreement, by approval of the Member or otherwise, both as to action in an indemnified capacity and as to action in any other capacity. The indemnification, contribution and advancement of expenses provided by or granted pursuant to this Section 12 shall continue as to a person who has ceased to be an indemnified representative in respect of matters arising prior to such time, and shall inure to the benefit of the successors, heirs, executors, administrators and personal representatives of such a person.

13. Amendments. This Agreement may be amended only upon the written consent of the Member.

14. Governing Law. This Agreement shall be governed by and construed in accordance with the domestic laws of the State of Delaware without giving effect to any choice of law or conflict of law provision or rule (whether the State of Delaware or any other jurisdiction) that would cause the application of the laws of any jurisdiction other than the State of Delaware.

Annex A-105

15. Singular; Plural; Gender. Wherever from the context it appears appropriate, each term stated in either the singular or the plural shall include the singular and the plural, and pronouns stated in either the masculine, the feminine or the neuter gender shall include the masculine, feminine and neuter.

16. Entire Agreement. This Agreement embodies the complete agreement and understanding among the parties hereto and supersedes and preempts any prior understandings, agreements or representations by or among the parties hereto, written or oral, which may have related to the subject matter hereof in any way.

The Board of Directors
Air Industries Group
1460 Fifth Avenue
Bay Shore, NY 11706

Ladies and Gentlemen:

We understand that Air Industries Group (the “Company”), proposes to enter into an Agreement and Plan of Merger, dated as of February 16, 2026 (the “Agreement”), with Tenax Aerospace Acquisition, LLC (“Tenax”) and Transitory Air Sub LLC, a wholly owned subsidiary of the Company (the “Merger Sub”). Pursuant to the Agreement, the Merger Sub will merge with and into Tenax, with Tenax being the surviving corporation as a wholly owned subsidiary of the Company (the “Merger”). As a result of the Merger, the membership units of Tenax will be converted into the right to receive 94,400,000 shares of common stock, par value $0.001 per share, of the Company (“Company Common Stock”), subject to adjustments pursuant to Section 3.03 of the Agreement, as to which adjustments we express no opinion (the “Adjustment Qualification”). Following the closing of the Merger, the Company will commence a cash tender offer (the “Tender Offer”) to acquire up to 1,000,000 shares of Company Common Stock at $4.10 per share, subject to the Adjustment Qualification. In addition, pursuant to the Agreement, the Company and a rights agent mutually agreeable to the Company and Tenax will enter into a Redemption Rights Agreement (the “Redemption Rights Agreement”), reflecting the terms and conditions set forth on Exhibit G of the Agreement, pursuant to which the holders of Company Common Stock as of the business day prior to the closing of the Merger will be granted the right to cause the Company to redeem their shares of Company Common Stock for $4.18 per share in cash (subject to the Adjustment Qualification), payable during a specified period following the first anniversary of the closing of the Merger (such $4.18 price per share, the “Redemption Price”) if during the 20 trading days prior to the first anniversary of the closing of the Merger the volume weighted average price of the shares of Company Common Stock is lower than $4.18, subject to the Adjustment Qualification (the “Redemption” and together with the Merger, the Tender Offer and the other transactions contemplated by the Agreement, the “Transaction”). The terms and conditions of the Transaction are more fully set forth in the Agreement.

The Board of Directors has asked us whether, in our opinion, the Redemption Price is fair, from a financial point of view, to the holders of the Company Common Stock.

In connection with rendering our opinion, we have, among other things:

(i)     reviewed certain publicly available business and financial information relating to the Company that we deemed to be relevant, including publicly available research analysts’ estimates;

(ii)    reviewed certain internal projected financial data relating to the Company prepared and furnished to us by management of the Company, each as approved for our use by the Company (the “Forecasts”);

(iii)   discussed with management of the Company their assessment of the past and current operations of the Company, the current financial condition and prospects of the Company, and the Forecasts;

(iv)   reviewed the reported prices and the historical trading activity of the Company Common Stock;

Annex B-1

Table of Contents

The Board of Directors

Air Industries Group

Page 2

(v)    compared the financial performance of the Company and its stock market trading multiples with those of certain other publicly traded companies that we deemed relevant;

(vi)   compared the financial performance of the Company and the valuation multiples relating to the Redemption Price with the financial terms, to the extent publicly available, of certain other transactions that we deemed relevant;

(vii)  reviewed the financial terms and conditions of a draft, dated as of February 16, 2026, of the Agreement, including Exhibit G; and

(viii) performed such other analyses and examinations and considered such other factors that we deemed appropriate.

For purposes of our analysis and opinion, we have assumed and relied upon the accuracy and completeness of the financial and other information publicly available, and all of the information supplied or otherwise made available to, discussed with, or reviewed by us, without any independent verification of such information (and have not assumed responsibility or liability for any independent verification of such information), and have further relied upon the assurances of the management of the Company that they are not aware of any facts or circumstances that would make such information inaccurate or misleading. With respect to the Forecasts, we have assumed with your consent that they have been reasonably prepared on bases reflecting the best currently available estimates and good faith judgments of the management of the Company as to the future financial performance of the Company and the other matters covered thereby. We express no view as to the Forecasts or the assumptions on which they are based.

For purposes of our analysis and opinion, we have assumed, in all respects material to our analysis, that the final executed Agreement will not differ from the draft Agreement reviewed by us, that the final executed Redemption Rights Agreement will not differ from the draft terms and conditions set forth on Exhibit G of the Agreement reviewed by us, that the representations and warranties of each party contained in the Agreement are true and correct, that each party will perform all of the covenants and agreements required to be performed by it under the Agreement and Redemption Rights Agreement and that all conditions to the consummation of the Transaction, including the Redemption, will be satisfied without waiver or modification thereof. We have further assumed, in all respects material to our analysis, that all governmental, regulatory or other consents, approvals or releases necessary for the consummation of the Transaction, including the Redemption, will be obtained without any delay, limitation, restriction or condition that would have an adverse effect on the Company or the consummation of the Transaction, including the Redemption, or reduce the contemplated benefits of the Transaction, including the Redemption, to the holders of the Company Common Stock.

We have not conducted a physical inspection of the properties or facilities of the Company and have not made or assumed any responsibility for making any independent valuation or appraisal of the assets or liabilities (including any contingent, derivative or other off-balance sheet assets and liabilities) of the Company, nor have we been furnished with any such valuations or appraisals, nor have we evaluated the solvency or fair value of the Company under any state or federal laws relating to bankruptcy, insolvency or similar matters. Our opinion is necessarily based upon information made available to us as of the date hereof and financial, economic, market and other conditions as they exist and as can be evaluated on the date hereof. It is understood that subsequent developments may affect this opinion and that we do not have any obligation to update, revise or reaffirm this opinion.

We have not been asked to pass upon, and express no opinion with respect to, any matter other than the fairness to the holders of the Company Common Stock, from a financial point of view, of the Redemption Price. We do not express any view on, and our opinion does not address, the fairness of the proposed transaction to, or any consideration received in connection therewith by, the holders of any other class of securities, creditors or other constituencies of the Company, the fairness of the consideration to be paid or payable by the Company to the holders of membership units of Tenax or to be paid or payable by the Company in the Tender Offer, nor the fairness of the amount or nature of any compensation to be paid or payable to any of the officers, directors or employees

of the Company, or any class of such persons, whether relative to the Redemption Price or otherwise. We have not been asked to, nor do we express any view on, and our opinion does not address, any other term or aspect of the Agreement or the Redemption Rights Agreement or the Transaction, including, without limitation, the structure or form of the Transaction, or any term or aspect of any other agreement or instrument contemplated by the Agreement or the Redemption Rights Agreement or entered into or amended in connection with the Agreement or the Redemption Rights Agreement. Our opinion does not address the relative merits of the Transaction, including the Redemption, as compared to other business or financial strategies that might be available to the Company, nor does it address the underlying business decision of the Company to engage in the Transaction, including the Redemption. Our opinion does not constitute a recommendation to the Board of Directors or to any other persons in respect of the Transaction, including the Redemption, including as to how any holder of shares of the Company Common Stock should vote or act in respect of the Transaction, including the Redemption. We are not expressing any opinion as to the prices at which shares of Company Common Stock will trade at any time, as to the potential effects of volatility in the credit, financial and stock markets on the Company or the Transaction, including the Redemption, or as to the impact of the Transaction, including the Redemption, on the solvency or viability of the Company or the ability of the Company to pay its obligations when they come due. We are not legal, regulatory, accounting or tax experts and have assumed the accuracy and completeness of assessments by the Company and its advisors with respect to legal, regulatory, accounting and tax matters.

We have acted as financial advisor to the Company in connection with the Transaction and will receive a fee for our services, a portion of which is payable upon rendering this opinion and a substantial portion of which is contingent upon the consummation of the Transaction. The Company has also agreed to reimburse our expenses and to indemnify us against certain liabilities arising out of our engagement. During the two year period prior to the date hereof, KippsDeSanto & Co. and its affiliates have not been engaged to provide financial advisory or other services to the Company and we have not received any compensation from the Company during such period. In addition, during the two year period prior to the date hereof, KippsDeSanto & Co. and its affiliates have not been engaged to provide financial advisory or other services to Tenax and we have not received any compensation from Tenax during such period. We may provide financial advisory or other services to the Company and Tenax in the future, and in connection with any such services we may receive compensation.

KippsDeSanto & Co. and its affiliates engage in a wide range of activities for our and their own accounts and the accounts of customers, including corporate finance, mergers and acquisitions, equity sales, trading and research, private equity, placement agent, asset management and related activities. In connection with these businesses or otherwise, KippsDeSanto & Co. and its affiliates and/or our or their respective employees, as well as investment funds in which any of them may have a financial interest, may at any time, directly or indirectly, hold long or short positions and may trade or otherwise effect transactions for their own accounts or the accounts of customers, in debt or equity securities, senior loans and/or derivative products or other financial instruments of or relating to the Company, Tenax, potential parties to the Transaction and/or any of their respective affiliates or persons that are competitors, customers or suppliers of the Company or Tenax.

Our financial advisory services and this opinion are provided for the information and benefit of the Board of Directors (in its capacity as such) in connection with its evaluation of the proposed Merger. The issuance of this opinion has been approved by an Opinion Committee of KippsDeSanto & Co.

Based upon and subject to the foregoing, it is our opinion that, as of the date hereof, the Redemption Price is fair, from a financial point of view, to the holders of the Company Common Stock.

 

Very truly yours,

   

KippsDeSanto & Co.

Section 2. Appointment of Rights Agent.

The Company hereby appoints the Rights Agent to act as agent for the Company in accordance with the terms and conditions of this Agreement, and the Rights Agent hereby accepts such appointment. The Rights Agent represents and warrants to the Company that it is duly organized, validly existing and in good standing under the laws of the jurisdiction of its organization, and that it has full power and authority to execute and deliver this Agreement and to perform its obligations hereunder, and that this Agreement has been duly authorized, executed and delivered by the Rights Agent and constitutes its legal, valid and binding obligation, enforceable against it in accordance with its terms.

Section 3. Issuance of the Rights.

(a) Until certificates evidencing the Rights are distributed to Existing Stockholders, the Rights shall be evidenced by the certificates for shares of Common Stock registered in the names of the Existing Stockholders (or, in the case of uncertificated shares of Common Stock, by the book-entry account that evidences record ownership of such shares) (which certificates or book entries for Common Stock shall be deemed also to be certificates or book entries for Rights), and not by separate certificates (or book entries), and registered holders of such shares of Common Stock shall also be the registered holders of the associated Rights. As of and after the Rights Distribution Date, the Rights shall be evidenced solely by the Rights Certificates.

(b) The Company shall promptly notify the Rights Agent of the Rights Distribution Date and request its transfer agent (if its transfer agent is not the Rights Agent) to give the Rights Agent a list of Existing Stockholders together with all other relevant information. Until such notice is received by the Rights Agent, the Rights Agent may presume conclusively for all purposes that the Rights Distribution Date has not occurred; providedhowever, that, for the avoidance of doubt, the failure of the Company to timely deliver such notice shall not alter, amend or modify the rights, privileges and obligations of the Existing Stockholders. As soon as practicable after the Rights Agent is notified of the Rights Distribution Date and receives such information, the Rights Agent shall send by first-class, postage prepaid mail, to the last address of each holder of record of Common Stock as of the Close of Business on the Business Day immediately preceding the Closing as it appears on the records of the Company or its transfer agent or registrar for Common Stock, with instructions to each holder of record to deliver such notice to the applicable Existing Stockholder, one or more certificates (the “Rights Certificates”), evidencing one Right for each share of Common Stock owned as of the Close of Business on the Record Date.

(c) No Rights shall be issued in respect of shares of Common Stock that are issued (whether originally issued or from the Company’s treasury) after the Record Date.

(d) In the event the Company purchases or acquires any shares of Common Stock after the Record Date but prior to the Rights Distribution Date, any Rights associated with such shares shall be deemed cancelled and of no further effect.

(e) The Rights and the Rights Certificates may not be sold, assigned or transferred, in whole or in part, in any manner. Any Right held by an Existing Stockholder shall automatically cease to exist upon any transfer, sale or assignment of beneficial ownership of the Subject Share to which such Right relates (it being understood that any administrative surrender of certificates for reissuance, consolidation or similar purposes that does not result in a change of beneficial ownership shall not cause such cessation).

(f) The Company shall make available, as promptly as practicable following the Rights Distribution Date, a copy of a Summary of Rights to Redeem Common Stock, in substantially the form attached as Exhibit A, to any Existing Stockholder who may request such information prior to the Expiration Time.

Section 4. Rights Certificates.

(a) The Rights Certificates shall be in substantially the form attached as Exhibit B and may have such marks of identification or designation and such legends, summaries or endorsements printed thereon as the Company may deem appropriate (but which do not affect the rights, duties, liabilities or responsibilities of the Rights Agent) and as are not inconsistent with the provisions of this Agreement, or as may be required to comply with any applicable law or with any rule or regulation made pursuant thereto, or to conform to customary usage. The Rights Certificates, whenever distributed, shall be dated as of the Record Date, and on their face shall entitle the holders thereof to require the Company to purchase the Subject Shares related thereto for an amount in cash equal to the Redemption Price during the Redemption Period.

Annex C-3

Table of Contents

(b) The Rights Certificates shall be executed on behalf of the Company by its Chief Executive Officer, President, Chief Financial Officer, Secretary or Treasurer, or any other authorized officer of the Company, either manually or by facsimile or other electronic signature. The Rights Certificates shall be countersigned manually or by facsimile or other electronic signature by the Rights Agent and shall not be valid for any purpose unless so countersigned. In case any authorized officer of the Company who shall have signed or attested any of the Rights Certificates shall cease to be an authorized officer of the Company before countersignature by the Rights Agent, such Rights Certificates may nevertheless be countersigned by the Rights Agent and issued and delivered with the same force and effect as though the Person who signed or attested such Rights Certificates had not ceased to be an authorized officer of the Company. In addition, any of the Rights Certificates may be signed or attested on behalf of the Company by any Person who, at the actual date of the execution of such Rights Certificate, is an authorized officer of the Company even if such Person was not an authorized officer of the Company at the date of the execution of this Agreement.

(c) Following the Rights Distribution Date, the Rights Agent shall keep or cause to be kept, at its principal office or offices designated as the appropriate place for surrender of Rights Certificates upon exercise, books for registration of the Rights Certificates issued hereunder. Such books shall show the names and addresses of the respective Existing Stockholders, the number of Rights evidenced on its face by each of the Rights Certificates held by each Existing Stockholder and the certificate number and the date of each of the Rights Certificates. The Rights Agent shall make such books available for inspection by the Company at any time during normal business hours upon reasonable prior written notice.

Section 5. Mutilated, Destroyed, Lost or Stolen Rights Certificates.

Upon receipt by the Company and the Rights Agent of (a) evidence reasonably satisfactory to the Company and the Rights Agent of the loss, theft, destruction or mutilation of a valid Rights Certificate, (b) (i) in the case of mutilation, the Rights Certificate or (ii) in the case of loss, theft or destruction, indemnity or security reasonably satisfactory to the Company and the Rights Agent and (c) reimbursement to the Company and the Rights Agent of all reasonable expenses incidental thereto, and, in the case of mutilation, upon cancellation of the Rights Certificate so surrendered, the Company shall prepare, execute and deliver a new Rights Certificate of like tenor to the Rights Agent for countersignature and delivery to the registered owner in lieu of the Rights Certificate so lost, stolen, destroyed or mutilated.

Section 6. Cancellation and Destruction of Rights Certificates.

All Rights Certificates surrendered for the purpose of exercise shall, if surrendered to the Company or any of its agents, be delivered to the Rights Agent for cancellation or in cancelled form or, if surrendered to the Rights Agent, shall be cancelled by it, and no Rights Certificates shall be issued in lieu thereof, except as expressly permitted by this Agreement. The Company shall deliver to the Rights Agent for cancellation and retirement, and the Rights Agent shall so cancel and retire, any other Rights Certificates purchased or acquired by the Company otherwise than upon the exercise thereof. At the expense of the Company, the Rights Agent shall deliver all cancelled Rights Certificates to the Company or shall, at the written request of the Company, destroy or cause to be destroyed such cancelled Rights Certificates, and in such case shall deliver a certificate of destruction thereof, executed by the Rights Agent, to the Company.

Section 7. Redemption Price; Measurement Period.

(a) Exercise of the Rights is subject to the following conditions:

(i)   such Existing Stockholder must have been a beneficial owner of shares of Common Stock as of the Close of Business on the Record Date;

(ii)  such Existing Stockholder must have remained continuously a beneficial owner of such shares of Common Stock to be redeemed from the Record Date until the expiration of the Redemption Period (i.e., such Existing Stockholder cannot have sold and repurchased such shares); and

(iii) during the 20 Trading Days prior to the first anniversary of the Closing, the volume weighted average price per share of the Common Stock must have been lower than the Redemption Price, rounded to the nearest cent, as the same may have been adjusted pursuant to Section 12.

Annex C-4

Table of Contents

(b) The price that the Company shall pay to purchase each Subject Share duly submitted to the Rights Agent for redemption upon the exercise of a Right is, subject to adjustment as provided in Section 12, an amount in cash equal to $[*]2 per share (the “Redemption Price”), and shall be payable in accordance with Section 8(b).

(c) The Company shall give written notice to the Existing Stockholders of the VWAP for the 20 full Trading Days ending on (and including) the Trading Day immediately preceding the Anniversary Date (the “Measurement Period”) not later than the second Business Day after the end of the Measurement Period by mailing such notice to the last address of each holder of record of Common Stock as of the Close of Business on the Business Day immediately preceding the Closing as it appears upon the registry books of the Rights Agent and instructing each holder of record to deliver such notice to the applicable Existing Stockholder, and (i) if the VWAP for the Measurement Period, rounded to the nearest cent, was lower than the Redemption Price (as the same may be amended from time to time in accordance with the provisions hereof), such notice shall confirm that the Rights may be exercised prior to the Expiration Time, or (ii) if the VWAP for the Measurement Period was equal to or in excess of the Redemption Price, such notice shall state that the Rights may not be exercised and have expired and that the Company has terminated this Agreement.

(d) No later than the Trading Day immediately following the Anniversary Date, the Company shall issue a press release and file a Current Report on Form 8-K reporting the VWAP for the Measurement Period, stating whether the VWAP for the Measurement Period, rounded to the nearest cent, was lower than the Redemption Price and, if so, instructing Existing Stockholders as to the procedure for exercising their Rights in accordance with Section 8.

(e) If, prior to the Anniversary Date, the Common Stock ceases to be listed on a national securities exchange or quoted on over-the-counter markets, so that Existing Stockholders and the Company cannot readily determine the VWAP for the Measurement Period, an Existing Stockholder may exercise the Rights associated with such Existing Stockholder’s Subject Shares and receive the Redemption Price for such Subject Shares.

Section 8. Exercise of Rights.

(a) An Existing Stockholder may exercise the Rights evidenced by its Rights Certificate (except as otherwise provided herein, including the restrictions on exercisability set forth in Section 7
