Rhea-AI Filing Summary

CECO Environmental Corp. agreed to acquire Thermon Group Holdings in a cash-and-stock merger valued at approximately $2.2 billion, creating a larger industrial environmental and thermal solutions company.

Thermon shareholders can elect for each share either $63.89 in cash, 0.8110 CECO shares, or a mix of $10.00 in cash plus 0.6840 CECO shares, subject to proration. The mixed option values Thermon at about $63.13 per share, a 26.8% premium to Thermon’s prior close. After closing, CECO and Thermon investors are expected to own roughly 62.5% and 37.5% of the combined company, respectively.

CECO has committed financing including a $200 million incremental term loan and access to revolving credit facilities, and intends to fund the deal with cash on hand and debt. The transaction, unanimously approved by both boards and supported by CECO holders owning about 15.2% of the vote, is targeted to close in mid-2026, subject to shareholder approvals, regulatory clearances, Nasdaq listing of new shares, and other customary conditions. Two Thermon directors will join CECO’s board at closing.

Positive

  • Strategic scale and diversification: The approximately $2.2 billion Thermon acquisition adds complementary industrial process heating and thermal management capabilities, expands exposure to energy transition and infrastructure end-markets, and is framed as supporting sustained double-digit growth with Thermon shareholders owning about 37.5% of the combined company.

Negative

  • Higher leverage and deal-contingent risks: Funding with cash plus a $200 million incremental term loan and large revolving facilities will increase debt, while closing depends on shareholder approvals, regulatory clearances, and carries sizable termination fees of $74.70 million or $105 million in certain break scenarios.

Insights

CECO’s $2.2B Thermon deal is a sizable, strategy-shaping merger funded partly with new debt.

CECO is pursuing a transformative acquisition of Thermon in a $2.2 billion cash-and-stock transaction. The structure offers Thermon holders cash, stock, or mixed consideration and implies a 26.8% premium to Thermon’s prior share price, with Thermon owners ending up with about 37.5% of the combined company.

Strategically, the combination adds industrial process heating and thermal management to CECO’s environmental solutions portfolio, broadening end-market exposure in areas like energy transition, power generation, and infrastructure. Management highlights expectations for sustained double-digit growth and an enhanced financial profile, although specific synergy targets are not quantified here.

Financing relies on cash plus borrowings, including a $200 million incremental term loan and significant revolving credit capacity, which will likely increase leverage. The merger faces standard risks: shareholder approvals at both companies, antitrust and regulatory clearance, integration execution, and potential termination fees of $74.70 million (Thermon) or $105 million (CECO) if certain break conditions occur. Progress milestones include completion of a Form S-4 registration and a targeted mid-2026 closing.

Item 1.01 Entry into a Material Definitive Agreement.

 

On February 23, 2026, CECO Environmental Corp., a Delaware corporation (the “Company”), Longhorn Merger Sub, Inc., a Delaware corporation and direct wholly owned subsidiary of the Company (“Merger Sub Inc.”), Longhorn Merger Sub LLC, a Delaware limited liability company and direct wholly owned subsidiary of the Company (“Merger Sub LLC”), and Thermon Group Holdings, Inc., a Delaware corporation (“Thermon”), entered into an Agreement and Plan of Merger (the “Merger Agreement”). Upon the terms and subject to the conditions set forth in the Merger Agreement, (i) Merger Sub Inc. will merge with and into Thermon (the “First Merger”), with Thermon continuing as the surviving entity (the “Surviving Corporation”), and (ii) immediately following the First Merger, the Surviving Corporation will merge with and into Merger Sub LLC (the “Second Merger” and, together with the First Merger, the “Mergers”), with Merger Sub LLC continuing as the surviving entity and a wholly owned subsidiary of the Company. The First Merger will become effective at a time agreed by the parties to the Merger Agreement in writing and as specified in a certificate of merger filed with the Secretary of State of the State of Delaware (the “Effective Time”), and the Second Merger will become effective as specified in a subsequent certificate of merger (the “Second Merger Effective Time”). Upon consummation of the Mergers and the other transactions contemplated by the Merger Agreement (the “Transactions”), Thermon and Merger Sub Inc. will cease to exist.

 

Under the terms of the Merger Agreement and as more fully described below, at the Effective Time, each share of common stock, par value $0.001 per share, of Thermon (“Thermon Common Stock”), issued and outstanding immediately prior to the Effective Time (other than those shares of Thermon Common Stock excluded or constituting dissenting shares pursuant to the Merger Agreement), will be automatically converted into the right to receive from the Company, pursuant to a properly made election that has actually been received by the Exchange Agent and not revoked prior to the election deadline to be determined by the Company and Thermon (the “Election Deadline”), and subject to the proration and allocation procedures set forth in the Merger Agreement, one of the following forms of consideration (i) a combination of 0.6840 shares of common stock, par value $0.01 per share, of the Company (“Company Common Stock”) and $10.00 in cash (the “Mixed Consideration”), (ii) $63.89 in cash (the “Cash Consideration”), or (iii) 0.8110 shares of Company Common Stock (the “Stock Consideration” and, together with the Mixed Consideration and the Cash Consideration, the “Merger Consideration”).

 

Under the Merger Agreement, at the Effective Time, each outstanding Thermon restricted stock unit and performance unit (a “Thermon PU”) will be assumed by the Company and converted into a restricted stock unit award of the Company based on the Stock Consideration exchange ratio. For Thermon PUs, the number of Thermon shares underlying such award will be calculated based on target or actual performance (depending on the status of the applicable performance period), and the converted Company awards will subsequently be subject only to time-based vesting. Each outstanding Thermon stock option with an exercise price less than the Cash Consideration will be cancelled and converted into the right to receive an amount in cash equal to the Cash Consideration less the applicable exercise price, while all other Thermon stock options will be automatically cancelled for no consideration.

 

The board of directors of the Company (the “Company Board”) unanimously (i) determined that the Mergers and the other transactions contemplated by the Merger Agreement (the “Transactions”) are in the best interests of, and are advisable to, the Company and its stockholders (the “Company Stockholders”), (ii) approved and declared advisable the Merger Agreement and the Transactions, (iii) directed that the issuance of the Company Common Stock constituting the Stock Consideration to be issued in the First Merger and other shares of Company Common Stock to be issued in the Mergers or reserved for issuance in connection with the Mergers, in each case, as provided in the Merger Agreement (the “Stock Issuance”) be submitted to the holders of the Company Common Stock for their approval and (iv) resolved to recommend that the Company Stockholders approve the Stock Issuance.

 

At the Effective Time, the Company Board will be increased from eight to 10 members, and the newly created vacancies on the Company Board will be filled by two directors currently serving as the members of board of directors of Thermon (the “Thermon Board” and such directors, the “Thermon Appointees”), one of which will be designated by Thermon, in its sole discretion, and one of which will be designated by mutual agreement of the Chairman of each of the Company Board and Thermon Board. If the Transactions close prior to the Company’s 2026 annual meeting of stockholders, the Company agreed to nominate the Thermon Appointees for reelection to the Company Board at such 2026 annual meeting.

 

 

 

 

The closing of the Mergers is subject to the satisfaction or waiver of certain closing conditions, including, among others, (i) adoption of the Merger Agreement by the affirmative vote of the holders of a majority of the outstanding shares of Thermon Common Stock entitled to vote thereon (the “Thermon Stockholder Approval”), (ii) approval of the Stock Issuance by the affirmative vote of a majority of the shares of the Company Common Stock present in person or represented by proxy at a meeting of the Company Stockholders and entitled to vote thereon in accordance with the rules and regulations of the Nasdaq Stock Market LLC (“Nasdaq”), the Delaware General Corporation Law and the Company organizational documents (the “Company Stockholder Approval”), (iii) the expiration or termination of any applicable waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, as well as any agreement not to close embodied in a “timing agreement” between the parties to the Merger Agreement and the applicable governmental entity, (iv) no temporary restraining order, preliminary or permanent injunction or other judgment, order or decree issued by any court of competent jurisdiction being in effect, and no material law having been enacted or promulgated after the date of the Merger Agreement in any jurisdiction material to the Company and its subsidiaries, taken as a whole, or to Thermon and its subsidiaries, taken as a whole, that, in any such case, prohibits or makes illegal the consummation of the Mergers, (v) approval for listing on the Nasdaq of the shares of the Company Common Stock to be issued in the First Merger, (vi) the effectiveness of the Form S-4, (vii) the accuracy of representations and warranties and compliance with covenants of each party (in each case certain to certain qualifications) and (viii) with respect to the obligations of Thermon, the receipt of (x) a customary tax opinion of counsel to Thermon and (y) the adoption by the Company of resolutions increasing the size of the Company Board and appointing the Thermon Appointees, in each case subject to the standards set forth in the Merger Agreement.

 

The Merger Agreement contains customary representations and warranties of the parties to the Merger Agreement relating to their respective businesses, financial statements and public filings, as applicable, in each case generally subject to customary materiality and knowledge qualifiers. Additionally, the Merger Agreement provides for customary pre-closing covenants of the Company and Thermon, including covenants relating to conducting their respective businesses in the ordinary course and refraining from taking certain actions without the consent of the other party. The Company and Thermon also agreed to use their reasonable best efforts to consummate the Transactions and to obtain regulatory approvals.

 

The Merger Agreement provides that, from the date of the Merger Agreement, each of the Company and Thermon will be subject to certain restrictions on its ability to solicit an alternative Parent Acquisition Proposal (with respect to the Company) or Company Acquisition Proposal (with respect to Thermon) (each as defined in the Merger Agreement), respectively, from third parties, to provide non-public information to third parties and to engage in discussions with third parties regarding alternative Parent Acquisition Proposals or Company Acquisition Proposals, as applicable, subject to customary exceptions.

 

The Merger Agreement contains customary termination rights for each of the Company and Thermon, including, among others, by either party if (i) the Mergers have not been consummated by August 24, 2026 (subject to a limited extension to November 23, 2026 for the sole purpose of obtaining antitrust clearances), (ii) if required stockholder approvals are not obtained, (iii) upon a change of recommendation by the other party’s board of directors, (iv)  if such party determines to enter into a definitive agreement providing for a Company Superior Proposal or Parent Superior Proposal (each as defined in the Merger Agreement), as applicable, or (v) upon a material breach by the other party that would result in the failure of a closing condition and is not cured within the specified time period, in each case on the terms set forth in the Merger Agreement. In certain circumstances, including specified circumstances following a change of recommendation by the Thermon Board or the receipt by Thermon of a competing acquisition proposal, Thermon will be required to pay the Company a termination fee of $74.70 million (the “Thermon Termination Fee”), and in reciprocal specified circumstances, the Company will be required to pay Thermon a termination fee of $105 million (the “Company Termination Fee”), in each case on the terms set forth in the Merger Agreement. The foregoing description is qualified in its entirety by reference to the full text of the Merger Agreement, which is attached as Exhibit 2.1 to this Current Report on Form 8-K.

 

 

 

 

The representations, warranties and covenants contained in the Merger Agreement have been made solely for the benefit of the parties thereto. In addition, such representations, warranties and covenants (i) have been made only for purposes of the Merger Agreement, (ii) have been qualified by (a) matters specifically disclosed in any reports filed by the Company or Thermon with the Securities and Exchange Commission (the “SEC”) prior to the date of the Merger Agreement (subject to certain exceptions) and (b) confidential disclosures made in confidential disclosure letters delivered in connection with the Merger Agreement, (iii) are subject to materiality qualifications contained in the Merger Agreement which may differ from what may be viewed as material by investors, (iv) were made only as of the date of the Merger Agreement or such other date as is specified in the Merger Agreement and (v) have been included in the Merger Agreement for the purpose of allocating risk between the contracting parties rather than establishing matters as fact. Accordingly, the Merger Agreement is included with this filing only to provide investors with information regarding the terms of the Merger Agreement, and not to provide investors with any other factual information regarding the parties thereto or their respective businesses. Investors should not rely on the representations, warranties and covenants or any descriptions thereof as characterizations of the actual state of facts or condition of the parties to the Merger Agreement or any of their respective subsidiaries or affiliates. Moreover, information concerning the subject matter of the representations and warranties may change after the date of the Merger Agreement, which subsequent information may or may not be fully reflected in the Company’s public disclosures. The Merger Agreement should not be read alone, but should instead be read in conjunction with the other information regarding the Company and Thermon that is or will be contained in, or incorporated by reference into, the Annual Reports on Form 10-K, Quarterly Reports on Form 10-Q and other documents that the Company or Thermon files with the SEC.

 

Financing

 

In connection with, and concurrently with the entry into, the Merger Agreement, the Company entered into a debt commitment letter (the “Commitment Letter”) dated February 23, 2026 with Bank of America, N.A. and BofA Securities, Inc. (“BofA”), pursuant to which BofA has committed, subject to satisfaction of standard conditions, to provide the Company with an incremental term loan facility in an aggregate principal amount of $200 million (the “Committed Loan Facility”) and contemplates utilizing up to $365 million of revolving credit loans under the Company’s existing credit facility, subject to obtaining certain requisite amendments under the Company’s existing credit facility. In the event these amendments are not obtained on or prior to the closing date of the merger, the Commitment Letter also provides a $700 million senior secured revolving credit facility to backstop and refinance the Company’s existing credit facility in full. The funding of these commitments is subject to customary conditions, including the consummation of the Mergers. The Company currently intends to fund the Transactions and related fees, costs and expenses with a combination of cash on hand, borrowings under the Company’s existing credit facility, subject to obtaining certain requisite amendments and, to the extent necessary, borrowings under the Committed Loan Facility.

 

Voting Agreements

 

Concurrently with the execution of the Merger Agreement, each of Jason DeZwirek, his affiliates Icarus Investment Corp. and 0to100 Inc., and Todd Gleason (collectively, the “Supporting Stockholders”), beneficially owning approximately 15.2% of the outstanding shares of Company Common Stock, entered into voting agreements with the Company and Thermon (the “Voting Agreements”), pursuant to which the Supporting Stockholders have agreed, among other things, to (i) refrain from transferring, selling, pledging, or otherwise disposing of any of their shares of Company Common Stock, subject to certain exceptions, (ii) vote all of their shares (A) in favor of the Stock Issuance and any other proposal considered and voted upon by the Company Stockholders at any meeting of the Company Stockholders necessary for consummation of the transactions contemplated by the Merger Agreement, including the Mergers, (B) against any (1) Parent Acquisition Proposal (as defined in the Merger Agreement), (2) reorganization, recapitalization, dissolution, liquidation or winding up of Parent or any of its Subsidiaries; and (3) action, proposal or agreement that would reasonably be expected to (x) result in a breach, in any material respect, of any covenant, representation or warranty of the Company, Merger Sub Inc. or Merger Sub LLC under the Merger Agreement or (y) prevent or materially delay or adversely affect the consummation of the Mergers, and (iii) grant an irrevocable proxy to enforce such voting obligations. The Voting Agreements terminate upon the earliest of the Effective Time, the termination of the Merger Agreement, the receipt of the Company Stockholder Approval, the occurrence of an adverse recommendation by the Company Board or the date the Merger Agreement is amended in certain specified manners.

This Current Report on Form 8-K contains “forward-looking statements” within the meaning of Section 27A of the Securities Act and Section 21E of the Exchange Act. All statements, other than statements of historical fact, included in this Form 8-K that address events, or developments that the Company and Thermon expect, believe, or anticipate will or may occur in the future are forward-looking statements. The words “intend,” “expect,” and similar expressions are intended to identify forward-looking statements. Forward-looking statements in this Current Report on Form 8-K include, but are not limited to, statements regarding the Transactions, pro forma descriptions of the combined company and its operations, integration and transition plans, synergies, opportunities and anticipated future performance. However, the absence of these words or similar expressions does not mean that a statement is not forward-looking.

 

 

 

 

There are a number of risks and uncertainties that could cause actual results to differ materially from the forward-looking statements included in this Current Report on Form 8-K. These include the expected timing and likelihood of completion of the Transaction, including the timing, receipt and terms and conditions of any required governmental and regulatory approvals of the Transaction that could reduce anticipated benefits or cause the parties to abandon the Transaction, the ability to successfully integrate the businesses, the occurrence of any event, change or other circumstances that could give rise to the termination of the Merger Agreement, the possibility that stockholders of the Company or Thermon may not approve the Transaction, the risk that the parties may not be able to satisfy the conditions to the Transaction in a timely manner or at all, risks related to disruption of management time from ongoing business operations due to the Transaction, the risk that any announcements relating to the Transactions could have adverse effects on the market price of the Company’s common stock or Thermon’s common stock, the risk that the Transactions and its announcement could have an adverse effect on the ability of the Company and Thermon to retain customers and retain and hire key personnel and maintain relationships with their suppliers and customers and on their operating results and businesses generally, the risk the pending Transactions could distract management of both entities and they will incur substantial costs, the risk that problems may arise in successfully integrating the businesses of the companies, which may result in the combined company not operating as effectively and efficiently as expected, the risk that the combined company may be unable to achieve synergies or it may take longer than expected to achieve those synergies and other important factors that could cause actual results to differ materially from those projected. All such factors are difficult to predict and are beyond the Company’s or Thermon’s control, including those detailed in the Company’s annual reports on Form 10-K, quarterly reports on Form 10-Q and current reports on Form 8-K that are available on its website at https://investors.cecoenviro.com and on the SEC’s website at https://www.sec.gov, and those detailed in Thermon’s annual reports on Form 10-K, quarterly reports on Form 10-Q and current reports on Form 8-K that are available on Thermon’s website at https://ir.thermon.com and on the SEC’s website at https://www.sec.gov.

Such forward-looking statements are based on assumptions and analyses made by the Company and Thermon in light of their perceptions of current conditions, expected future developments, and other factors that the Company and Thermon believe are appropriate under the circumstances. These statements are subject to a number of known and unknown risks and uncertainties.

Together, we will build on our shared histories to deliver a broader, more integrated set of mission-critical solutions for our customers and drive long-term growth and value for our stakeholders. We are excited to welcome the Thermon team to CECO and unite our two great organizations.”

FAQ

What transaction did CECO (CECO) announce with Thermon Group Holdings?

CECO agreed to acquire Thermon in a cash-and-stock merger valued at about $2.2 billion. The deal combines CECO’s environmental solutions with Thermon’s industrial process heating and thermal capabilities, creating a larger industrial platform serving energy transition, infrastructure, and other mission-critical end markets.

What consideration will Thermon shareholders receive in the CECO merger?

Thermon shareholders can elect cash, stock, or a mixed package from CECO. They may choose $63.89 in cash, 0.8110 CECO shares, or $10.00 in cash plus 0.6840 CECO shares per Thermon share, subject to proration and allocation limits on overall cash and stock paid.

How does the CECO–Thermon merger value Thermon’s shares and what is the premium?

The mixed consideration values Thermon at about $63.13 per share. This is based on CECO’s $77.68 closing price on February 23, 2026, and represents roughly a 26.8% premium to Thermon’s $49.77 closing price on the same date, as disclosed in the transaction announcement.

How will ownership of the combined CECO and Thermon company be split after closing?

Post-transaction, CECO and Thermon shareholders are expected to own 62.5% and 37.5%, respectively. This ownership mix reflects the agreed cash-and-stock structure and implies that Thermon investors will hold a substantial minority stake in the enlarged CECO-led industrial solutions platform.

How is CECO financing the acquisition of Thermon Group Holdings?

CECO plans to fund the deal with cash on hand and new debt facilities. It has a commitment for a $200 million incremental term loan and expects to use up to $365 million of its existing revolver, with a $700 million backstop revolver available if required amendments are not secured.

What approvals and conditions must be satisfied for the CECO–Thermon merger to close?

The merger requires shareholder approvals, regulatory clearances, and Nasdaq listing of new CECO shares. Conditions include Thermon stockholder adoption of the merger agreement, CECO stockholder approval of share issuance, Hart-Scott-Rodino waiting period expiration, an effective Form S-4, and customary accuracy-of-representations and covenant-compliance tests.

When is the CECO and Thermon transaction expected to close and how were boards involved?

The companies currently anticipate closing the transaction in mid-2026. The merger agreement was unanimously approved by both boards of directors, and CECO obtained voting agreements from stockholders representing about 15.2% of its voting power to support approval of the stock issuance and related proposals.
