Rhea-AI Filing Summary

Soluna Holdings, Inc. is calling a virtual annual stockholder meeting on October 16, 2026 to vote on several matters. Stockholders will elect three Class III directors to terms ending in 2029, consider an amendment to increase authorized common stock from 375,000,000 to 1,000,000,000 shares, and vote on an advisory resolution approving executive compensation. Other items include ratifying KPMG LLP as independent auditor for 2026, approving for Nasdaq Listing Rule 5635(d) purposes the potential issuance of 20% or more of current common stock under a Standby Equity Purchase Agreement with YA II PN, Ltd., and permitting adjournment if needed to secure sufficient votes.

For 2025 the company reported a net loss of $56.991 million. CEO John Belizaire’s total compensation was $6.0 million, and Executive Chairman Michael Toporek received $12.5 million, largely in equity awards. As of August 10, 2026 there were 244,590,575 common shares outstanding; insiders and directors as a group beneficially owned about 15.5%, and one outside holder owned 6.3%.

Positive

  • None.

Negative

  • Significant potential dilution capacity via proposal to increase authorized common stock from 375,000,000 to 1,000,000,000 shares.
  • Potential issuance of 20%+ of outstanding shares under the Standby Equity Purchase Agreement with YA II PN, Ltd., subject to stockholder approval under Nasdaq Listing Rule 5635(d).
  • Large executive equity awards in 2025, including $6.0 million in total pay for the CEO and $12.5 million for the Executive Chairman, alongside a $56.991 million net loss.

Filing Explained

The preliminary proxy leaves capital-capacity proposals pending and ends new dilution-protection grants after 2026, with existing unvested awards continuing.

Soluna’s preliminary proxy is a request for the October 16, 2026 stockholder vote; its capital-capacity proposals remain pending, so they do not yet change the company’s authorized shares or permit the proposed SEPA issuance.

The company will sunset new grants under its True-Up Agreements after December 31, 2026, with a final grant date of January 15, 2027; previously granted unvested awards continue under their existing schedules, and no replacement dilution-protection arrangements are planned.

The equity-plan table also reports 10,696,014 shares remaining available for future issuance, with additional quarterly reserve increases specified for the 2021 and 2023 plans; this is stated plan capacity rather than an issuance reported here.

Governance will also be put to a vote: Thomas Marusak will not seek reelection, while William Hazelip, Michael Toporek, and Daniel Golding are nominated for Class III terms ending at the 2029 annual meeting if elected.

The relevant resolution points are the stockholder vote on October 16, 2026 and the True-Up Agreements’ final grant date of January 15, 2027.

Authorized common stock (current) 375,000,000 shares Existing authorization prior to proposed amendment to Articles of Incorporation
Proposed authorized common stock 1,000,000,000 shares Proposed increase in authorized common stock for stockholder approval in 2026
Shares outstanding 244,590,575 shares Common stock outstanding as of August 10, 2026 entitled to vote at the meeting
Net loss 2025 $56,991,000 Net loss for the year ended December 31, 2025 in pay versus performance table
CEO total compensation 2025 $6,007,746 Total compensation for CEO John Belizaire for fiscal year 2025
Executive Chairman compensation 2025 $12,513,764 Total compensation for Executive Chairman Michael Toporek in 2025
Total shareholder return 2025 $56 Value of a fixed $100 investment based on 2025 total shareholder return
Insiders’ ownership 15.5% Beneficial ownership of all current directors, nominees and executive officers as a group
Nasdaq Listing Rule 5635(d) regulatory
"for purposes of complying with Nasdaq Listing Rule 5635(d), the potential issuance of 20% or more"
Nasdaq Listing Rule 5635(d) is a stock-exchange rule that determines when a company must get shareholder approval before issuing new shares tied to conversions or exercises of existing convertible securities, options or warrants. It matters to investors because it controls potential dilution of their holdings and changes in voting power—think of it like a rule that decides whether a previously agreed‑upon coupon can be redeemed without asking the group again.
Standby Equity Purchase Agreement financial
"pursuant to the Standby Equity Purchase Agreement between the Company and YA II PN, Ltd."
A standby equity purchase agreement is a contract in which an investor or group agrees to buy a company’s newly issued shares on demand, giving the company a ready source of cash it can tap when needed. Think of it like a line of credit made with stock instead of a loan: it provides financial backup but can increase the number of shares outstanding, diluting existing owners and affecting per‑share value, so investors watch these deals for their impact on ownership and earnings per share.
broker non-votes regulatory
"As a result, withheld votes and “broker non-votes” will not affect the outcome"
Broker non-votes occur when a brokerage firm is unable to vote on a shareholder’s behalf during a company election or decision because the shareholder has not given specific voting instructions, and the broker is not allowed or chooses not to vote on certain matters. They are important because they can affect the outcome of votes, especially when the results are close, by effectively reducing the total number of votes cast.
Total Shareholder Return financial
"Value of Initial Fixed $100 Investment based on Total Shareholder Return"
Total shareholder return is the overall gain an investor gets from owning a stock, combining changes in the share price plus any cash payouts like dividends, and assuming those payouts are reinvested in more shares. Investors use it like a single score that shows the true return on their investment—similar to checking both the growth of a savings account and the interest earned—to compare how well different companies or investments perform over time.
audit committee financial expert regulatory
"the Board has determined that Ms. Budzyn qualifies as an “audit committee financial expert”"
A person on a company’s board who has deep knowledge of accounting, financial reporting and auditing, able to understand and question the books, controls and audit work like a trained mechanic inspecting an engine. Investors care because that expertise helps spot errors, weaknesses or misleading statements early, improving the likelihood that financial reports are accurate and reducing the risk of surprises that can hurt a company’s value.
clawback policy financial
"The Board adopted a written policy to recover “excess” compensation that is granted, earned, or vested"
A clawback policy is a company rule that lets the firm take back pay, bonuses or stock awards from current or former executives if results are later found to be incorrect, misconduct occurred, or targets were missed. It matters to investors because it helps protect the value of their holdings by discouraging risky or fraudulent behavior and ensuring executive rewards reflect real, verified performance—think of it as a return policy for executive pay.

Even if you plan to attend our Annual Meeting, we recommend that you also submit your proxy as described above so that your vote will be counted if you later decide not to attend our Annual Meeting.
The proxies to vote that are submitted electronically, telephonically or represented by the proxy cards received, properly marked, dated, signed and not revoked, will be voted at the Annual Meeting.
What if I vote and then change my mind?
You may revoke your proxy at any time before it is exercised by:
filing with the Secretary of the Company a notice of revocation;
submitting a later-dated proxy to vote by telephone or on the Internet;
sending in another duly executed proxy bearing a later date; or
attending the Annual Meeting remotely and casting your vote in the manner set forth above.
Your latest proxy or vote will be the vote that is counted.
What is the difference between holding shares as a stockholder of record and as a beneficial owner?
Many of our stockholders hold their shares through a stockbroker, bank or other nominee rather than directly in their own name. As summarized below, there are some distinctions between shares held of record and those owned beneficially.
3


Stockholder of Record
If your shares are registered directly in your name with our transfer agent, Equiniti Trust Company LLC, you are considered, with respect to those shares, the stockholder of record. As the stockholder of record, you have the right to directly grant your voting proxy or to vote at the Annual Meeting.
Beneficial Owner
If your shares are held in a stock brokerage account or by a bank or other nominee, you are considered the beneficial owner of shares held in street name, and these proxy materials are being forwarded to you by your broker, bank or nominee which is considered, with respect to those shares, the stockholder of record. As the beneficial owner, you have the right to direct your broker as to how to vote and are also invited to attend the Annual Meeting. However, because you are not the stockholder of record, you may not vote these shares unless you obtain a signed proxy from the record holder giving you the right to vote the shares. If you do not provide the stockholder of record with voting instructions or otherwise obtain a signed proxy from the record holder giving you the right to vote the shares, broker non-votes may occur for the shares that you beneficially own. The effect of broker non-votes is more specifically described in “What vote is required to approve each proposal?” below.
What vote is required to approve each proposal?
Assuming that a quorum is present, the following votes will be required to approve each proposal:
With respect to the Director Proposal, directors are elected by a plurality of the votes cast by holders of our common stock, present in person or represented by proxy and entitled to vote on the election of directors. The director nominees who receive the greatest number of votes at the Annual Meeting (up to the total number of directors to be elected) will be elected. As a result, withheld votes and “broker non-votes” (see below), if any, will not affect the outcome of the vote on the Director Proposal. Consequently, only shares that are voted in favor of a particular nominee will be counted toward such nominee’s achievement of a plurality. You may not vote your shares cumulatively for the election of directors.
With respect to the Increase in Authorized Proposal, the Say-on-Pay Proposal, the Auditor Proposal, the Exchange Cap Proposal, and the Adjournment Proposal, as well as the approval of any other matter that may properly come before the Annual Meeting, the affirmative vote of the holders of a majority of the votes cast by holders of our common stock, present in person or represented by proxy, is required to approve these proposals. As a result, abstentions, broker non-votes, if any, and any other failure to submit a proxy or vote in person at the meeting, will not affect the outcome of the vote of the Increase in Authorized Proposal, the Say-on-Pay Proposal, the Auditor Proposal, the Exchange Cap Proposal, and the Adjournment Proposal. If any of these proposals are deemed "routine" as described below, no broker non-votes will occur on such proposal.
Under Nevada law, the Company’s stockholders are not entitled to dissenter’s or appraisal rights in connection with any of the proposals to be acted upon at the Annual Meeting.
What are “broker non-votes”?
Banks and brokers acting as nominees are permitted to use discretionary voting authority to vote proxies for proposals that are deemed “routine” by the New York Stock Exchange, which means that they can submit a proxy or cast a ballot on behalf of stockholders who do not provide a specific voting instruction. Brokers and banks are not permitted to use discretionary voting authority to vote proxies for proposals that are deemed “non-routine” by the New York Stock Exchange. The determination of which proposals are deemed “routine” versus “non-routine” may not be made by the New York Stock Exchange until after the date on which this Proxy Statement has been mailed to you. As such, it is important that you provide voting instructions to your bank, broker or other nominee, if you wish to ensure that your shares are present and voted at the Annual Meeting on all matters and if you wish to direct the voting of your shares on “routine” matters.
A broker non-vote occurs when there is at least one “routine” matter to be considered at a meeting and a broker submits a proxy to vote on at least one “routine” proposal but does not vote on a given proposal because the broker does not have discretionary power for that particular item and has not received instructions from the beneficial owner on that proposal.
4


Under the applicable rules governing such brokers, we believe the Increase in Authorized Proposal, the Auditor Proposal and the Adjournment Proposal are likely to be considered “routine” items. This means that brokers may vote using their discretion on such proposals on behalf of beneficial owners who have not furnished voting instructions. In contrast, certain items are considered “non-routine,” and a “broker non-vote” occurs when brokers do not receive voting instructions from beneficial owners with respect to such items because the brokers are not entitled to vote such uninstructed shares. We believe the Director Proposal the Say-on-Pay Proposal, and the Exchange Cap Proposal are likely to be considered “non-routine”, which means that brokers cannot vote your uninstructed shares when they do not receive voting instructions from you.
How are we soliciting this proxy?
We are soliciting this proxy on behalf of our Board and will pay all expenses associated therewith. Some of our officers, directors and other employees also may, but without compensation other than their regular compensation, solicit proxies by further mailing or personal conversations, or by telephone, facsimile or other electronic means.
We will also, upon request, reimburse brokers and other persons holding stock in their names, or in the names of nominees, for their reasonable out-of-pocket expenses for forwarding proxy materials to the beneficial owners of the capital stock and to obtain proxies.
In addition, we have engaged Alliance Advisors to assist in the solicitation of proxies and provide related informational support, for a service fee, which is not expected to exceed $20,000.

PROPOSAL 1: TO ELECT THREE DIRECTORS AS CLASS III DIRECTORS TO SERVE
THREE-YEAR TERMS EXPIRING AT THE ANNUAL MEETING IN 2029 AND
UNTIL THEIR SUCCESSORS HAVE BEEN DULY ELECTED AND QUALIFIED
Our Board is divided into three classes: Class I, Class II and Class III, with each class serving a three-year term. Vacancies on the Board may be filled only by the affirmative vote of a majority of the total remaining directors then in office, even if less than a quorum, or by a sole remaining director. A director elected by the Board to fill a vacancy in a class or a newly created directorship created by an increase in the number of directors in a class, shall serve for the remainder of the full term of that class and until the director’s successor is duly elected and qualified.
Our Board presently has ten members. There are three directors in the class (Class III) whose term of office expire in 2026. Thomas Marusak, one of the current Class III directors, will not be standing for re-election at the Annual Meeting. William Hazelip, Michael Toporek and Daniel Golding have been nominated for election as Class III directors at the Annual Meeting. If elected at the Annual Meeting, such nominees would serve until our 2029 annual meeting and until their successors have been duly elected and qualified, or, if sooner, until their earlier resignation, death or removal.
Directors are elected by a plurality of the votes cast. Stockholders may not vote, or submit a proxy, for more than one nominee. The nominee receiving the highest number of affirmative votes will be elected. Unless otherwise directed, shares represented by executed proxies will be voted for the election of William Hazelip, Michael Toporek and Daniel Golding. If the director nominees become unavailable for election as a result of an unexpected occurrence, shares that would have been voted for the nominee will instead be voted for the election of substitute nominees proposed by our Board. The director nominees have agreed to serve if elected. Our management has no reason to believe that the director nominees will be unable to serve.

Class III Nominees for Election for a Term Expiring at the 2029 Annual Meeting
The following table sets forth the name, age and position and tenure of the individuals nominated for election as our Class III directors for terms expiring at the 2029 annual meeting:

CORPORATE GOVERNANCE

Board of Directors Composition
Our Board is currently composed of ten directors. Our directors hold office until their successors have been elected and qualified or until the earlier of their resignation or removal.
We have no formal policy regarding board diversity. Our priority in selection of Board members is identification of members who will further the interests of our stockholders through their established record of professional accomplishment, the ability to contribute positively to the collaborative culture among Board members, knowledge of our business and understanding of the competitive landscape.
Board of Directors Meetings
Our Board met 23 times in 2025. Each director attended at least 75% of the aggregate of (i) the total number of meetings of our Board (held during the period for which such director served on the Board) and (ii) the total number of meetings of all committees of our Board on which such director served (during the periods for which the director served on such committee or committees). We do not have a formal policy requiring members of the Board to attend our annual meetings. 7 members of the Board attended our 2025 annual meeting of stockholders, which was held remotely.
Director Independence
Pursuant to the rules of Nasdaq, a director will only qualify as an “independent director” if, in the opinion of that company’s board of directors, that person does not have a relationship that would interfere with the exercise of independent judgment in carrying out the responsibilities of a director.
Under such rules, the Board has determined that Messrs. Bottomley, Hazelip, Hirshfield, Michaels, Marusak (Messr. Marusak will not be standing for reelection at the Annual Meeting), Phelan and Golding, and Ms. Budzyn are “independent directors,” as defined by the rules and listing standards of Nasdaq. Messrs. Belizaire, Lipman and Toporek are not independent directors under the Nasdaq rules. In making such independence determinations, our Board considered the relationships that each non-employee director has with us and all other facts and circumstances that our Board deemed relevant in determining their independence, including the beneficial ownership of our capital stock by each non-employee director. In considering the independence of the directors listed above, our Board considered the association of our directors with the holders of more than 5% of our common stock. There are no family relationships among any of our directors and executive officers.
Board Of Directors Committees
The Board has an Audit Committee, a Nominating and Corporate Governance Committee, a Compensation Committee, and an Executive Committee.
Audit Committee
The Board has adopted an Audit Committee charter, which is published on our website at https://www.solunacomputing.com/investors/governance/. The Audit Committee consists of Ms. Budzyn (chair) and Messrs. Hirshfield, Phelan and Bottomley. The Audit Committee met 4 times in 2025. The Board has determined that each member of the Audit Committee is independent, as defined under the applicable rules and listing standards of Nasdaq and SEC rules and regulations. In addition, the Board has determined that Ms. Budzyn qualifies as an “audit committee financial expert” as defined in the rules and regulations of the SEC.
The Audit Committee’s primary function is to assist the Board in fulfilling its oversight responsibilities by reviewing the financial information to be provided to the stockholders and others, the system of internal controls which management has established and the audit and financial reporting process. The Audit Committee, among other matters, (1) is responsible for the annual appointment of, and for compensating, retaining, overseeing, ensuring independence of, and, where appropriate, replacing, the independent registered public accounting firm as the Company’s auditors, (2) reviews the arrangements for and the results of the auditors’ examination of our books and records, and (3) assists the Board in its oversight of the reliability and integrity of the Company’s accounting policies, financial statements and financial reporting, and disclosure practices, including its system of internal controls, (4) the establishment and maintenance of processes to ensure compliance with all relevant laws, regulations, and Company policies, (5) is responsible for the Company’s policies with respect to risk assessment and risk management pertaining to the financial, accounting and tax matters of the Company, and 6) reviews annually the adequacy of the charter of the Audit Committee and recommends changes to the Board that it considers necessary or appropriate.

Executive Committee
The Board formed an Executive Committee in January 2022 and adopted an Executive Committee charter, which is published on our website at https://www.solunacomputing.com/investors/governance/. The Executive Committee as of the date of this report consists of Messrs. Phelan (Chair), Bottomley, Lipman, Toporek and Michaels. The Board has determined that each of Messrs. Phelan, Bottomley and Michaels are independent, as defined under the applicable rules and listing standards of Nasdaq.
The Executive Committee met 19 times in fiscal year 2025. The purpose of the Executive Committee is to represent and assist the Board in its review and approval of certain transactions and other matters requiring Board consideration, and to take action, where necessary, appropriate and authorized by the Board during intervals between regular and special meetings of the Board. The Executive Committee has authority to: 1) monitor management’s performance against the approved budget of record; 2) authorize mining equipment purchase transactions; 3) authorize the price at which equity securities of the Company are sold; 4) authorize the payment of dividends to holders of preferred stock of the Company; and 5) identify and assess business risks and develop and propose recommendations to management and the Board to minimize such risks. Notwithstanding anything in the foregoing, the Executive Committee is not authorized to 1) take any action that requires an adoption by an independent majority of the Board; 2) complete any transaction that would have a material effect on the Company’s financial statements; or 3) complete any transaction that qualifies as a related party transaction.
Board Leadership Structure and Role in Risk Oversight
The Board executes its oversight responsibility for risk management directly and through its Committees, as follows:
The Audit Committee has primary responsibility for overseeing the integrity of the Company’s financial reporting risk by reviewing: (i) the Company’s disclosure controls and procedures; (ii) any significant deficiencies in the design or operation of internal controls; (iii) any fraud material or otherwise; (iv) the use of judgments in management’s preparation of the financial statements; and (v) through consultation with Company’s independent registered public accounting firm on the above items. The Board is kept abreast of the Committee’s risk oversight and other activities via reports of the Committee Chairman to the full Board.
The Compensation Committee oversees the risks associated with our compensation policies and practices, with respect to both executive compensation and compensation generally. The Board is kept abreast of the Committee’s risk oversight and other activities via reports of the Committee Chairman to the full Board.
The Executive Committee is responsible for identifying and assessing business risks and proposing recommendations to management and the full Board. The Board is kept abreast of the Committee’s risk oversight and other activities via reports of the Committee Chairman to the full Board.
The Board considers specific risk topics, including risks associated with our strategic plan, our capital structure, and our development activities. In addition, the Board receives detailed regular reports from the heads of our principal business and corporate functions that include discussions of the risks and exposures involved in their respective areas of responsibility. These reports are provided in connection with every regular Board meeting and are discussed, as necessary, at Board meetings. Further, the Board is routinely informed of developments at the Company that could affect our risk profile or other aspects of our business.
We do not believe that the Board’s role in risk oversight has any impact on its leadership structure, as discussed below.
Executive Sessions of Directors
Executive sessions, or meetings of outside (non-management) directors without management present, are held periodically throughout the year. At these executive sessions, the outside directors review, among other things, the criteria upon which the performance of the Chief Executive Officer and other executive officers is based, the performance of the Chief Executive Officer against such criteria, and the compensation of the Chief Executive Officer and other executive officers. Meetings are held from time to time with the Chief Executive Officer to discuss relevant subjects.
Board Leadership Structure
The Board recognizes that one of its key responsibilities is to evaluate and determine its optimal leadership structure so as to provide independent oversight of management. The Board understands that there is no single, generally accepted
12


approach to providing Board leadership and that given the dynamic and competitive environment in which we operate, the right Board leadership structure may vary as circumstances warrant. As of the date of this Proxy Statement, Michael Toporek serves as Executive Chairman of the Board and William Phelan serves as our Lead Independent Director. The Board recognizes that it is important to determine an optimal board leadership structure to ensure the independent oversight of management as the Company continues to grow. Michael Toporek had served as our Chief Executive Officer since October 2020, and effective May 1, 2023, John Belizaire began service as Chief Executive Officer and Michael Toporek serves as Executive Chairman. The Chief Executive Officer is responsible for setting the strategic direction for the Company and the day-to-day leadership and performance of the Company, while the Executive Chairman of the Board provides guidance to the Chief Executive Officer and presides over meetings of the full Board and the Lead Independent Director, coordinates the activities of the other independent directors and performs such other duties and responsibilities as the Board may determine. We believe that this separation of responsibilities also provides a balanced approach to managing the Board and overseeing the Company.
In considering its leadership structure, the Board has taken a number of factors into account. The Board, which consists of directors who are highly qualified and experienced, eight of whom are independent directors, exercises a strong, independent oversight function. This oversight function is enhanced by the fact that the Board’s three of the four standing committees – the Audit Committee, the Nominating and Corporate Governance Committee and the Compensation Committee – are comprised solely of independent directors and the Executive Committee, is comprised of a majority of independent directors.
Stockholder Communications
Stockholders who wish to communicate with the Board, or a particular director, may send a letter to our Secretary at 325 Washington Avenue Extension, Albany, New York 12205. The mailing envelope must contain a clear notation indicating that the enclosed letter is a “Stockholder-Board Communication.” All such letters must identify the author as a stockholder and clearly state whether the intended recipients are all members of the Board or certain specified individual directors. The Secretary will make copies of all such letters and circulate them to the appropriate director or directors.
Code of Business Conduct and Ethics
We have adopted a written code of conduct and ethics that applies to our directors, officers, contractors, and employees, including our principal executive officer, principal financial officer, principal accounting officer or controller, or persons performing similar functions. A current copy of our code is posted on our website, which is located at www.solunacomputing.com. We intend to disclose future amendments to certain provisions of our code of conduct and ethics, or waivers of such provisions applicable to any principal executive officer, principal financial officer, principal accounting officer or controller, or persons performing similar functions, and our directors, on our website identified above or in filings with the SEC.
Insider Trading Policy
The Company has an insider trading policy governing the purchase, sale and other dispositions of the Company’s securities that applies to all of the Company’s directors, officers, and employees. The Company believes that its insider trading policy is reasonably designed to promote compliance with insider trading laws, rules and regulations, and listing standards applicable to the Company. A copy of the Company’s insider trading policy is filed as Exhibit 19.1 to our Annual Report on Form 10-K for the fiscal year ended December 31, 2025.
Anti-Hedging Policy
Under the terms of our insider trading policy, we prohibit all Company personnel, including directors, officers, and employees, from engaging in certain forms of hedging transactions. Such transactions include those, such as puts and calls, and other derivative securities, that would allow them to lock in much of the value of their stock holdings, often in exchange for all or part of the potential for upside appreciation in the stock, and to continue to own the covered securities but without the full risks and rewards of ownership.
Clawback Policy
The Board adopted a written policy to recover “excess” compensation that is granted, earned, or vested based wholly or in part upon the attainment of a financial reporting measure. The compensation includes both cash-based and equity-based incentives. The compensation covered includes incentive awards awarded to any individuals (including former employees) who served as an executive officer during the three most recently completed fiscal years preceding the date on
13


which the preparation of an accounting restatement is required, provided that the executive officers were awarded more incentive awards than they would have received if the financial statements had been prepared correctly. The recovery will include an executive incentive award even if the executive was not involved in preparing the financial statements or did not commit misconduct that led to the restatement. Restatements attributable to an inadvertent error also will subject executive officers to the recovery of previously received incentive awards.

Securities Authorized for Issuance Under Equity Compensation Plans
The following table presents certain information as of December 31, 2025, with respect to the Soluna Holdings, Inc. Third Amended and Restated 2021 Stock Incentive Plan (the “2021 Plan”) and the Soluna Holdings, Inc. Amended and Restated 2023 Stock Incentive Plan (the “2023 Plan,” together with the 2021 Plan, the “Plans”), under which equity securities of the Company are authorized for issuance:

(1)The securities available under the Plans for issuance and issuable pursuant to exercises of outstanding options may be adjusted in the event of a change in outstanding stock by reason of stock dividend, stock splits, reverse stock splits, etc.
(2)On the first trading day of each quarter commencing January 1, 2025 and continuing through the second quarter of the fiscal year ending December 31, 2027, the number of shares of our common stock reserved for issuance under the 2021 Plan shall increase by 22.75% of the number of shares of common stock outstanding on such date. On the first trading day of each quarter commencing July 1, 2023, the number of shares of our common stock reserved for issuance under the 2023 Plan shall increase by 23.75% of the number of shares of common stock outstanding on such date.

In connection with the ongoing simplification of the Company’s executive compensation program, on January 21, 2026, the Board and the Compensation Committee determined to sunset the issuances of additional dilution protection grants pursuant to the Master Restricted Stock Agreements entered into with certain employees and directors of the Company (collectively, the "True-Up Agreements") after the specified cessation date of December 31, 2026. The final grant date for all applicable issuances of common stock during the last calendar quarter of such periods and for any portion of such periods for which a grant was not previously made shall be January 15, 2027. The True-Up Agreements entitled each recipient to periodic grants of restricted stock calculated by reference to a specified percentage of certain equity issuances by the Company during the rolling quarterly measurement periods. The Company does not intend to enter into any new or replacement dilution protection arrangements following the sunsetting of these arrangements. Any shares of restricted stock previously granted under the True-Up Agreements that remain unvested will continue to vest in accordance with their original vesting schedules. The Compensation Committee believes that the sunsetting of these arrangements, which were adopted at a time when the Company's capital structure involved significant dilutive financing transactions, is appropriate given the Company's current capital position and aligns the Company's executive compensation program more closely with the practices of its peers.

Prerequisites and Other Benefits
Our executive officers are eligible to participate in similar benefit plans available to all our other employees including medical, dental, vision, group life, disability, accidental death and dismemberment, paid time off, and 401(k) plan benefits.
We also maintain a standard directors and officers liability insurance policy with coverage similar to the coverage typically provided by other small publicly-held technology companies.

TRANSACTIONS WITH RELATED PERSONS
The following is a description of transactions since January 1, 2024, and each currently proposed transaction in which:

We have been or are to be a participant;
the amount involved exceeded or will exceed the lesser of $120,000 or 1% of our total assets at year-end for our last two completed fiscal years; and
any of our directors, executive officers or beneficial owners of more than 5% of our capital stock, or any immediate family member of, or person sharing the household with, any of these individuals or entities, had or will have a direct or indirect material interest, other than compensation and other arrangements that are described in the section titled “Executive Compensation.”

HEL Transactions

On October 29, 2021, the Company completed the Soluna Callisto acquisition pursuant to a merger agreement (the “Merger Agreement”). The purpose of the transaction was for SCI to acquire substantially all of the assets (other than those assets physically located in Morocco) formerly held by Harmattan Energy, Ltd. (formerly Soluna Technologies, Ltd.) (“HEL”), which assets consisted of SCI’s existing pipeline of certain cryptocurrency mining projects that HEL previously transferred to SCI, which was formed expressly for this purpose, and to provide SCI with the opportunity to directly employ or retain the services of four individuals whose services it had retained through HEL prior to the merger. As a result of the merger, each share of common stock of Soluna Callisto issued and outstanding immediately prior to the effective time of the merger, other than shares owned by the Company or any of our subsidiaries, was canceled and converted into the right to receive a proportionate share of up to 118,800 shares (the “Merger Shares”) of Mechanical Technology, Incorporated common stock, payable upon the achievement of certain milestones.

Due to conditions being met within the Merger Agreement in relation to energization and retention of employees, the Company has advised SCI US Holdings LLC, a Delaware limited liability company, who is the sole Effective Time Holder (as defined in the Merger Agreement) of the right to receive the Merger Shares and that 19,800 Merger Shares were issued on May 26, 2023, 39,600 Merger Shares were issued on October 10, 2023, and 17,820 Merger Shares were issued on October 8, 2025. SCI US Holdings LLC has consented to the issuance of such Merger Shares as required under the Merger Agreement and has directed the Company to issue such Merger Shares to its affiliate, HEL. On February 6, 2026, the Company issued an additional 10,692 Merger Shares, due to 18 MW of energization being met. The remaining 30,888 Merger Shares were issued on June 24, 2026, and therefore closes out the 118,800 Merger Shares available for issuance, and no further Merger Shares remains available pursuant to the terms of the Merger Agreement as of June 30, 2026.

Four of the Company’s directors have various affiliations with HEL.

Michael Toporek, the former Chief Executive Officer, and current Executive Chairman of the Board of the Company, owns (i) 90% of the equity of Soluna Technologies Investment I, LLC, which owns 57.9% of HEL and (ii) 100% of the equity of MJT Park Investors, Inc., which owns 3.1% of HEL, in each case, on a fully diluted basis. Mr. Toporek does not own directly, or indirectly, any equity interest in Tera Joule, LLC (“Tera Joule”), which owns 9.2% of HEL; however, as a result of his 100% ownership of Brookstone IAC, Inc. (“Brookstone IAC”), which is the manager of Tera Joule, he has dispositive power over the equity interests that Tera Joule owns in HEL.

In addition, one of the Company’s directors, Matthew E. Lipman, serves as a director and is currently acting as President of HEL. Mr. Lipman does not directly own any equity interest in Tera Joule, which owns 9.2% of HEL; however, as a result of his position as a director and officer of Brookstone IAC, which is the manager of Tera Joule, he has dispositive power over the equity interests that Tera Joule owns in HEL. As a result, the approximate dollar value of the amount of Mr. Toporek’s and Mr. Lipman’s interest in the Company’s transactions with HEL for the year ended December 31, 2025 was $0 and $0.

John Belizaire, the Company’s Chief Executive Officer, and John Bottomley, who were elected to the Board upon the effective time of SCI’s acquisition of Soluna Callisto, serve as directors of HEL. In addition, Mr. Belizaire is the beneficial owner of 1,317,567 shares of common stock of HEL and 102,380 Class Seed Preferred shares, which are convertible into 86,763 shares of common stock of HEL. These interests give Mr. Belizaire an ownership of 10.54% in HEL. Mr. Belizaire also owns an interest in HEL indirectly through his 5.0139% interest of Tera Joule’s 965,945 Class Seed Preferred shares, which are convertible into 818,596 shares of common stock of HEL. Mr. Bottomley is the beneficial owner of 96,189, or approximately 0.72%, of the outstanding shares of common stock of HEL.

26


The Company’s investment in HEL was initially carried at the cost of investment and was $750 thousand. Based on evaluation of projections for the Company’s investment in HEL, the Company fully impaired the equity investment of $750 thousand as of December 31, 2022, writing it down to $0.

The Company owned approximately 1.79% of HEL, calculated on a converted fully diluted basis, as of December 31, 2025. The Company may enter into additional transactions with HEL in the future.

MeOH Power, Inc.

On December 18, 2013, MeOH Power, Inc. and the Company executed a Senior Demand Promissory Note (the Note) in the amount of $380 thousand to secure the intercompany amounts due to the Company from MeOH Power, Inc. upon the deconsolidation of MeOH Power, Inc. Interest accrues on the Note at the Prime Rate in effect on the first business day of the month, as published in the Wall Street Journal. At the Company’s option, all or part of the principal and interest due on this Note may be converted to shares of common stock of MeOH Power, Inc. at a rate of $0.07 per share. Interest began accruing on January 1, 2014. The Company recorded a full allowance against the Note. As of December 31, 2025 and December 31, 2024, $403 thousand and $385 thousand, respectively, of principal and interest are available to convert into shares of common stock of MeOH Power, Inc. Any adjustments to the allowance are recorded as miscellaneous expenses during the period incurred.

Policies and Procedures for Related Party Transactions
We have adopted a written policy requiring that all related person transactions be reported to our executive management and/or the Board and approved or ratified by the Audit Committee. In completing its review of proposed related person transactions, the Audit Committee considers the aggregate value of the transaction, whether the transaction was undertaken in the ordinary course of business, the nature of the relationships involved, and whether the transaction is on terms comparable to those that could be obtained in arm’s length dealings with an unrelated third party.

PROPOSAL 2: APPROVAL OF AN AMENDMENT TO THE ARTICLES TO INCREASE THE NUMBER OF SHARES OF COMMON STOCK AUTHORIZED FOR ISSUANCE THEREUNDER FROM 375,000,000 SHARES TO 1,000,000,000 SHARES

As of the date of this proxy statement, we were authorized under our Articles to issue up to a total of 385,000,000 shares of capital stock, comprised of 375,000,000 shares of common stock and 10,000,000 shares of preferred stock, par value $0.001 per share. Our Board believes that it is in the best interests of the Company and our stockholders to amend the Articles to increase the number of authorized shares of common stock. Upon consultation with our management, our Board unanimously approved, and unanimously recommends for stockholder approval, the Increase in Authorized Proposal (the “Amendment”), to increase the number of shares of common stock authorized for issuance thereunder from 375,000,000 shares to 1,000,000,000 shares, each share of common stock having a par value of $0.001. The Amendment does not affect the number of shares of preferred stock authorized for issuance under the Articles.

The form of the text of the Amendment (which would be filed with the Nevada Secretary of State on its then-prescribed form of Certificate of Amendment) is set forth as Appendix A to this proxy statement (subject to any changes required by applicable law).

As of the Record Date, there were shares of our common stock outstanding and:
         shares of our common stock issuable upon the exercise of options outstanding at a weighted average exercise price of $ per share;
          shares of our common stock underlying restricted stock units; and
          shares of our common stock issuable upon the exercise of outstanding warrants, at a weighted average exercise price of $ per share.
The additional shares of common stock to be authorized by approval of the Amendment would have rights identical to the currently outstanding shares of common stock. Approval of the Amendment would not affect the rights of the holders of currently outstanding common stock, except, to the extent the additional authorized shares are issued, for effects incidental to increasing the number of shares of common stock outstanding, such as dilution of earnings per share and voting rights of current holders of common stock. If the Amendment is approved, it will become effective upon the filing of the Amendment with the Nevada Secretary of State on its then-prescribed form of Certificate of Amendment (or at a post-filing effective date and time, if any, stated therein, which may not be later than 90 days after such filing).

The description of the Amendment should be read in conjunction with and is qualified in its entirety by reference to the text of the proposed Amendment attached to this proxy statement as Appendix A.

Purpose of the Proposal

The approval of the Amendment is important for our ongoing business. Our Board believes it would be prudent and advisable to have the additional shares available to provide flexibility for the potential use of shares of common stock for business and financial purposes in the future. The Company continues construction and development of its various projects, as further described in our SEC filings. These projects require significant equity investment by the Company, which the Company intends to satisfy with proceeds from capital raising activities (including pursuant to the Standby Equity Purchase Agreement, dated March 24, 2026, between the Company and YA II PN, Ltd. (the “SEPA”) and the At the Market Offering Agreement, dated April 29, 2025, between the Company and H.C. Wainwright & Co., LLC (the “ATM Agreement”)), which may require the Company to issue common or preferred stock, or related derivative securities convertible into common stock. As previously announced, the Company continues to opportunistically explore various financing options for these activities, including negotiating term sheets and letters of intent with various lenders and investors. The Company may be engaged in multiple conversations and negotiations with various financing sources at any point in time, and such discussions may be in varying stages of negotiation at any point in time. No assurance can be given that any of the financing options considered by the Company will be on terms acceptable to the Company or will be completed at all. Nevertheless, the Company desires to be in a position to execute on one or more of these financings. Many of these potential financing alternatives require the Company to issue common or preferred stock, or related derivative securities convertible into common stock. Under the Articles, the Company has limited remaining authorized and unissued shares of common stock at its disposal. The Board determined that additional authorized shares of common stock were necessary to pursue future financing options. The Board’s intention in seeking stockholder approval for the Increase in Authorized Proposal is to utilize newly authorized shares of common stock for future financing options, as well as the other uses discussed below.
28



The Board has determined that no increase in the number of authorized preferred stock is necessary at this time.

Having an increased number of authorized but unissued shares of common stock would allow us to take prompt action with respect to corporate opportunities that develop. The additional shares could be used for various purposes without further stockholder approval. These purposes may include: (i) as discussed above, raising capital, if we have an appropriate opportunity, through offerings of common stock, or securities that are convertible into common stock; (ii) expanding our business through potential strategic transactions; (iii) establishing strategic relationships with other companies; (iv) exchanges of common stock, or securities that are convertible into common stock for other outstanding securities; (v) providing equity incentives pursuant to our equity incentive plans, or another plan we may adopt in the future, to attract and retain employees, officers or directors; and (vi) other general corporate purposes. We intend to use the additional shares of common stock that will be available to undertake any such issuances described above.

As is the case with the shares of common stock which are currently authorized but unissued, if the Amendment is approved by the holders of our common stock, the Board will only have authority to issue the additional shares of common stock from time to time without further action on the part of stockholders to the extent not prohibited by applicable law or by the rules of any stock exchange or market on which our securities may then be listed or authorized for quotation. Because it is anticipated that our directors and executive officers will be granted additional equity awards under our equity incentive plans, or another plan we adopt in the future, they may be deemed to have an indirect interest in the Amendment, because absent the Amendment, we may not have sufficient authorized shares to grant such awards.

The increase in authorized shares of our common stock will not have any immediate effect on the rights of existing stockholders. However, because our stockholders do not have any preemptive rights, future issuance of shares of common stock, or securities exercisable for or convertible into shares of common stock could have a dilutive effect on our earnings per share, book value per share, and the voting rights of stockholders and could have a negative effect on the price of our common stock.

Disadvantages to an increase in the number of authorized shares of common stock may include:
Stockholders may experience further dilution of their ownership.
Stockholders will not have any preemptive or similar rights to subscribe for or purchase any additional shares of common stock that may be issued in the future, and therefore, future issuances of common stock, depending on the circumstances, will have a dilutive effect on the earnings per share, voting power and other interests of our existing stockholders.
The additional shares of common stock for which authorization is sought in this proposal would be part of the existing class of common stock and, if and when issued, would have the same rights and privileges as the shares of common stock presently outstanding.

Additionally, the issuance of authorized but unissued shares of common stock could be used to deter a potential takeover of us that may otherwise be beneficial to stockholders by diluting the shares held by a potential suitor or issuing shares to a stockholder that will vote in accordance with the Board’s desires. A takeover may be beneficial to independent stockholders because, among other reasons, a potential suitor may offer such stockholders a premium for their shares of stock compared to the then-existing market price. We have not entered into any plans or agreements that may have material anti-takeover consequences.

We have no specific plan, commitment, arrangement, understanding or agreement, either oral or written, regarding the issuance of common stock subsequent to this proposed increase in the number of authorized shares at this time, and we have not allocated any specific portion of the proposed increase in the authorized number of shares to any particular purpose. However, we have in the past conducted certain public and private offerings of common stock, preferred stock and warrants, and we will continue to require additional capital in the near future (including pursuant to the SEPA and the ATM Agreement) to fund our projects and operations. As a result, it is foreseeable that we will seek to issue such additional shares of common stock in connection with any such capital raising activities, or any of the other activities described above. The Board does not intend to issue any shares of common stock, or securities convertible into shares of common stock except on terms that the Board deems to be in the interests of us and our stockholders. We are therefore requesting that our stockholders approve this proposal to amend our Articles to increase the number of shares of common stock authorized for issuance thereunder from 375,000,000 shares to 1,000,000,000 shares.

29


Required Vote

Pursuant to NRS 78.390, as amended effective May 30, 2025, by Assembly Bill No. 239, since the Increase in Authorized Proposal relates solely to an increase in the number of authorized shares of common stock, the holders of the common stock, as the class or series affected by the amendment, must approve the proposed amendment. In accordance with our Bylaws, Nevada law and the Nasdaq Listing Rules, such approval requires the affirmative vote of the holders of a majority of the votes cast in person via attendance at the virtual Annual Meeting or by proxy. As a result, abstentions and broker non-votes, if any, will not affect the outcome of the vote on this proposal. If this proposal is deemed to be “routine” as described above, no broker non-votes will occur on this proposal.

THE BOARD OF DIRECTORS RECOMMENDS THE HOLDERS OF COMMON STOCK VOTE “FOR” THE APPROVAL OF AN AMENDMENT TO THE ARTICLES TO INCREASE THE NUMBER OF SHARES OF COMMON STOCK AUTHORIZED FOR ISSUANCE THEREUNDER FROM 375,000,000 SHARES TO 1,000,000,000 SHARES.



PROPOSAL 3: ADVISORY VOTE ON EXECUTIVE COMPENSATION

As required by The Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010 (known as the Dodd-Frank Act), the Board is seeking advisory (non-binding) stockholder approval on the compensation of our named executive officers as disclosed in the section of this proxy statement titled “Executive Compensation.” The vote on this resolution is not intended to address any specific element of compensation, but rather relates to the overall compensation of our named executive officers as described in this Proxy Statement in accordance with the compensation disclosure rules of the SEC. This vote provides stockholders with the opportunity to endorse or not endorse the compensation of our named executive officers.

Our executive compensation programs are designed to attract, motivate, and retain our named executive officers, who are critical to our strategic goals and success. Under our executive compensation program, our named executive officers receive compensation related to the attainment of financial and other performance measures that, the Board believes, promotes the creation of long-term stockholder value and positions the Company for both near-term and long-term growth and success. Please read “Executive Compensation” for additional details about our executive compensation programs, including information about fiscal year 2024 and 2025 compensation of our named executive officers.

The Compensation Committee bases its executive compensation decisions on our compensation objectives, which include the following:
aligning management’s incentives with the interests of our stockholders;
providing competitive compensation to our named executive officers;
rewarding named executive officers for past performance and motivating them to excel in the future; and
rewarding superior performance of both the Company and each individual executive, and encouraging actions that promote our near-term and long-term strategic goals.

We believe that our existing compensation programs, which include a mix of fixed and performance-based compensation, and the terms of long-term incentive awards granted to our named executive officers, are all designed to motivate our named executive officers to achieve improved performance, align compensation with performance measures and stockholder interests, and enable us to attract, retain, and motivate talented executive officers, while at the same time creating a close relationship between performance and compensation. The Compensation Committee and the Board believe that the design of the Company’s executive compensation program, and hence the compensation awarded to named executive officers under the current program, fulfills this objective.

We are asking our stockholders to indicate their support for our named executive officers’ compensation as described in this Proxy Statement. This proposal, commonly known as a “say-on-pay” proposal, gives our stockholders the opportunity to express their views on our named executive officers’ compensation. Accordingly, we are asking our stockholders to approve, on an advisory basis, the compensation of the named executive officers by approving the following resolution:

30


RESOLVED, that the compensation paid to the Company’s named executive officers, as disclosed pursuant to Item 402 of Regulation S-K, including the compensation tables and narrative discussion, is hereby APPROVED.

The say-on-pay vote is advisory, and therefore not binding on the Company, the Compensation Committee, or the Board, however, the Board and the Compensation Committee value the opinions of our stockholders and will review and consider the outcome of this advisory vote when making future compensation decisions for our named executive officers.

Required Vote

In accordance with our Bylaws, Nevada law and the Nasdaq Listing Rules, such approval requires the affirmative vote of the holders of a majority of the votes cast in person via attendance at the virtual Annual Meeting or by proxy. As a result, abstentions and broker non-votes, if any, will not affect the outcome of the vote on this proposal. If this proposal is deemed to be “routine” as described above, no broker non-votes will occur on this proposal.

THE BOARD RECOMMENDS THAT THE STOCKHOLDERS VOTE “FOR” THE APPROVAL, ON AN ADVISORY BASIS OF THE EXECUTIVE COMPENSATION OF THE COMPANY'S NAMED EXECUTIVE OFFICERS.

PROPOSAL 4: RATIFY THE APPOINTMENT OF KPMG LLP AS OUR INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM FOR THE YEAR ENDING DECEMBER 31, 2026
Principal Accountant Fees and Services
The Audit Committee of the Board has appointed KPMG LLP ("KPMG") to serve as our independent registered public accounting firm for the fiscal year ending December 31, 2026.
On March 29, 2026, the Company notified UHY LLP (“UHY”) that UHY would be dismissed as the Company’s independent registered public accounting firm. The Audit Committee approved the decision to dismiss UHY, which became effective on March 29, 2026.

The audit reports of UHY on the Company’s financial statements as of and for the fiscal years ended December 31, 2025 and 2024 did not contain an adverse opinion or a disclaimer of opinion, and were not qualified or modified as to uncertainty, audit scope, or accounting principles.

During the Company’s two most recent fiscal years ended December 31, 2025 and 2024, and through March 29, 2026, the Company did not have any disagreement with UHY on any matter of accounting principles or practices, financial statement disclosure or auditing scope or procedures, which disagreement, if not resolved to UHY’s satisfaction, would have caused UHY to make reference to the subject matter of the disagreement in its reports on the Company’s financial statements. In addition, during the Company’s two most recent fiscal years ended December 31, 2025 and 2024, and through March 29, 2026, there were no “reportable events” as that term is defined in Item 304(a)(1)(v) of Regulation S-K.

On March 29, 2026, the Audit Committee approved the appointment of KPMG as the Company’s new independent registered public accounting firm for the fiscal year ended December 31, 2026.

During the fiscal years ended December 31, 2025 and 2024 and the subsequent interim period through March 29, 2026, neither the Company nor anyone acting on its behalf consulted KPMG on any matter relating to either (i) the application of accounting principles to a specific transaction, either completed or contemplated, or the type of audit opinion that might be rendered on the Company’s financial statements or (ii) any matter that was the subject of a disagreement (as that term is defined in Item 304(a)(1)(iv) of Regulation S-K and the related instructions) or a “reportable event” (as that term is defined in Item 304(a)(1)(v) of Regulation S-K).

No professional services were rendered by KPMG for each of the last two fiscal years.

The following table summarizes the fees paid for professional services rendered by UHY LLP for each of the last two fiscal years:

All Other Fees
All other fees for the fiscal year December 31, 2025 and 2024 were for professional services rendered for standalone financial statements audits and related audit procedures of multiple subsidiaries of Soluna Digital, Inc.

PROPOSAL 5: APPROVAL OF, FOR PURPOSES OF COMPLYING WITH NASDAQ LISTING RULE 5635(D), THE POTENTIAL ISSUANCE OF 20% OR MORE OF THE COMPANY’S ISSUED AND OUTSTANDING SHARES OF COMMON STOCK PURSUANT TO THE SEPA

Our common stock is currently listed on The Nasdaq Capital Market and, as such, we are subject to Nasdaq rules, which require us to obtain stockholder approval prior to the issuance of our common stock in connection with certain non-public offerings involving the sale, issuance or potential issuance by the Company of common stock (or securities convertible into or exercisable for common stock) equal to 20% or more of the common stock outstanding before the issuance.

Overview

On March 24, 2026, the Company entered into the SEPA with YA pursuant to which the Company has the right to sell to YA up to $250 million of common stock, subject to certain limitations and conditions set forth in the SEPA, from time to time during the term of the SEPA.

Upon the satisfaction of the conditions to YA’s purchase obligation set forth in the SEPA, including having a registration statement registering the resale of the shares of common stock issuable under the SEPA declared effective by the Securities and Exchange Commission (the “SEC”), the Company will have the right, but not the obligation, from time to time at its discretion, to direct YA to purchase a specified number of shares of common stock (an “Advance”) by delivering written notice to YA (an “Advance Notice”). While there is no mandatory minimum amount for any Advance, the maximum advance amount applicable to such Advance will be an amount equal to one hundred percent (100%) of the average of the daily trading volume of the common stock during regular trading hours as reported by Bloomberg L.P. (“Daily Traded Amount”) during the five consecutive Trading Days immediately preceding the date of such Advance Notice.

The shares of common stock purchased pursuant to an Advance will be issued and sold to YA under one of two pricing options at the election of the Company. Under the first option (“Pricing Option 1”), the Company will sell the shares of common stock to YA at 96% of the Market Price (as defined below) for any period commencing (i) if submitted to YA prior to 9:00 a.m. Eastern Time on a trading day, at the open of trading on such day or (ii) if submitted to YA after 9:00 a.m. Eastern Time on a trading day, upon receipt by the Company of written confirmation of acceptance of the advance notice by YA and, in either case, ending at 4:00 p.m. New York City time on the applicable advance notice date (the “Option 1 Pricing Period”). Under the second option (“Pricing Option 2”), the Company will sell the shares of common stock to YA at 97% of the Market Price for the three consecutive trading days commencing on the advance notice date (the “Option 2 Pricing Period”). “Market Price” is defined as, for any Option 1 Pricing Period, the daily volume weighted average price (“VWAP”) of the common stock on Nasdaq during the Option 1 Pricing Period, and for any Option 2 Pricing Period, the lowest VWAP of the common stock on the Nasdaq during the Option 2 Pricing Period.

Under applicable Nasdaq rules and the terms of the SEPA, in no event may the Company issue to YA under the SEPA shares of common stock equal to greater than 19.99% of the shares of common stock outstanding immediately prior to the execution of the SEPA (the “Exchange Cap”), unless (i) the Company obtains stockholder approval to issue shares of common stock in excess of the Exchange Cap in accordance with applicable Nasdaq rules, or (ii) the average price per share paid by YA for all of the shares of common stock that the Company directs YA to purchase from the Company pursuant to the SEPA, if any, equals or exceeds the lower of (a) the official closing price of the common stock on Nasdaq immediately preceding the execution of the SEPA and (b) the average official closing price of the common stock on Nasdaq for the five consecutive trading days immediately preceding the execution of the SEPA, adjusted as required by Nasdaq. Moreover, the Company may not issue or sell any shares of common stock to YA under the SEPA which, when aggregated with all other shares of common stock then beneficially owned by YA and its affiliates (as calculated pursuant to Section 13(d) of the Exchange Act and Rule 13d-3 thereunder), would result in YA beneficially owning more than 4.99% of the outstanding shares of common stock.

Actual sales of shares of common stock to YA as an Advance under the SEPA will depend on a variety of factors to be determined by the Company from time to time, which may include, among other things, market conditions, the trading price of the common stock and determinations by the Company as to the appropriate sources of funding for its business and operations.

The SEPA will automatically terminate on the earliest to occur of (i) the 36-month anniversary of the execution date of the SEPA or (ii) the date on which the Company shall have made full issuances of Advances pursuant to the SEPA.
34


The Company has the right to terminate the SEPA at no cost or penalty upon five (5) trading days’ prior written notice to YA, provided that there are no outstanding Advance Notices for which shares of common stock need to be issued and the Company has paid all amounts owed to YA pursuant to the SEPA.

The net proceeds under the SEPA to the Company will depend on the frequency and prices at which common stock is sold. The Company expects that proceeds received from such sales will be used primarily for working capital and general corporate purposes.

Reasons for Financing

We believe that the SEPA transaction provides necessary additional sources of capital to the Company. The proceeds that we expect to receive from this transaction will allow the Company to fund its business operations. This transaction provides the Company with future flexibility to enhance its liquidity in an opportunistic and efficient manner, and only when the Company deems it to be necessary.

Reasons for the Stockholder Approval

Our common stock is listed on Nasdaq, and as a result, we are subject to the Nasdaq Listing Rules. In order to comply with the Nasdaq Listing Rules, we are seeking stockholder approval of this proposal to potentially sell additional shares of common stock above the Exchange Cap.

Nasdaq Listing Rule 5635(d) requires stockholder approval prior to the issuance of securities in connection with a transaction other than a public offering involving the sale, issuance or potential issuance of common stock (or securities convertible into or exercisable for common stock) in an amount equal to 20% or more of the common stock or 20% or more of the voting power outstanding before the issuance at a price less than the “Minimum Price.” The Minimum Price is defined as the lower of (i) the closing price of the common stock immediately preceding the signing of the sale agreement or (ii) the average closing price of the common stock for the five trading days immediately preceding the signing of the sale agreement.

Accordingly, we are seeking stockholder approval under Nasdaq Listing Rule 5635(d) for the sale, issuance or potential issuance by us of common stock under the SEPA (or securities convertible into or exercisable for our common stock) in excess of 20% of the shares of our common stock outstanding immediately prior to the SEPA at an exercise price less than the Minimum Price.

Consequences of Not Approving this Proposal

The Board is not seeking the approval of our stockholders to authorize our entry into the SEPA. The SEPA has already been executed and delivered, and the closing of the SEPA has occurred. The failure of our stockholders to approve this proposal will mean that the issuance of shares of common stock in accordance with the SEPA will be limited to an amount up to the Exchange Cap and we will not be able to realize the full benefit of this financing transaction.

Additional Information

We intend this summary to provide you with basic information concerning the SEPA. The full text of the SEPA is filed as Exhibit 10.114 to our Current Report on Form 8-K filed with the SEC on March 30, 2026.

Required Vote

In accordance with our Bylaws, Nevada law and the Nasdaq Listing Rules, such approval requires the affirmative vote of the holders of a majority of the votes cast in person via attendance at the virtual Annual Meeting or by proxy. As a result, abstentions and broker non-votes, if any, will not affect the outcome of the vote on this proposal. If this proposal is deemed to be “routine” as described above, no broker non-votes will occur on this proposal.

THE BOARD RECOMMENDS THAT THE STOCKHOLDERS VOTE “FOR” THE APPROVAL OF, FOR PURPOSES OF COMPLYING WITH NASDAQ LISTING RULE 5635(D), THE POTENTIAL ISSUANCE OF 20% OR MORE OF THE COMPANY’S ISSUED AND OUTSTANDING SHARES OF COMMON STOCK PURSUANT TO THE SEPA.

PROPOSAL 6: APPROVAL OF THE ADJOURNMENT OF THE ANNUAL MEETING IN THE EVENT THAT THE NUMBER OF SHARES OF COMMON STOCK PRESENT OR REPRESENTED BY PROXY AT THE ANNUAL MEETING AND VOTING “FOR” THE APPROVAL OF ANY OF THE FOREGOING PROPOSALS ARE INSUFFICIENT TO APPROVE SUCH PROPOSAL

Adjournment of the Annual Meeting

In the event that the number of shares of common stock present or represented by proxy at the Annual Meeting and voting “FOR” the approval of any of the foregoing proposals is insufficient to approve such proposal, we may move to adjourn the Annual Meeting in order to enable us to solicit additional proxies in favor of the approval of such proposal. In that event, we will ask stockholders to vote only upon the Adjournment Proposal and not on any other proposal discussed in this Proxy Statement. If the adjournment is for more than sixty (60) days after the date set for the Annual Meeting, the Board will fix a new record date and, a notice of the new meeting shall be given to each stockholder of record entitled to vote at such meeting.
For the avoidance of doubt, any proxy authorizing the adjournment of the Annual Meeting shall also authorize successive adjournments thereof, at any meeting so adjourned, to the extent necessary for us to solicit additional proxies in favor of the approval of any such proposal.
Required Vote
The approval of the Adjournment Proposal will require the affirmative vote of the holders of a majority of the votes cast in person via attendance at the virtual Annual Meeting or by proxy and voting at the Annual Meeting. As a result, abstentions and broker non-votes, if any, will not affect the outcome on the vote of this proposal.
THE BOARD RECOMMENDS A VOTE “FOR” THE ADJOURNMENT OF THE ANNUAL MEETING IN THE EVENT THAT THE NUMBER OF SHARES OF COMMON STOCK PRESENT OR REPRESENTED BY PROXY AT THE ANNUAL MEETING AND VOTING “FOR” THE APPROVAL OF ANY OF THE FOREGOING PROPOSALS ARE INSUFFICIENT TO APPROVE SUCH PROPOSAL.
