Summary
Thermon Group Holdings completed its merger with CECO Environmental on June 1, 2026, with shareholders receiving approximately $329.4 million in cash plus 22.53 million CECO shares for the 32.94 million Thermon shares outstanding. The transaction closed as a tax-free reorganization under Section 368(a), and CECO simultaneously paid off Thermon's existing JPMorgan Chase credit facility.
Thermon's NYSE listing was terminated and trading suspended effective June 1, with the company filing Form 15 to end SEC reporting obligations as it becomes a wholly-owned CECO subsidiary. All Thermon directors and executive officers departed upon merger completion, a standard consequence of acquisition transactions.
The filing explicitly states director departures were not due to disagreements on operations, policies, or practices. Former Thermon shareholders who elected stock consideration are now governed by CECO's charter and bylaws. Two former Thermon directors, Victor Richey and Marcus George, joined CECO's board. CECO scheduled a June 9 conference call to discuss integration plans and expected synergies from the combined industrial solutions platform.

In connection with the consummation of the Mergers, CECO paid or caused to be paid, on behalf of Thermon, all amounts necessary to satisfy and discharge in full the then-outstanding obligations of Thermon under that certain Amended and Restated Credit Agreement, dated September 29, 2021, by and among Thermon Holding Corp., Thermon Canada Inc., the other financial institutions or entities party thereto from time to time and JPMorgan Chase Bank, N.A., as Administrative Agent, which was further amended on November 19, 2021, March 7, 2023, and December 29, 2023 (as amended, restated, supplemented or otherwise modified from time to time, together with all related credit documentation, the “Credit Agreement”). In connection therewith, the Credit Agreement and all commitments thereunder were terminated.
Thermon's existing credit facility with JPMorgan Chase Bank as administrative agent was fully repaid and terminated as part of the merger transaction with CECO. CECO paid all outstanding obligations on Thermon's behalf, eliminating Thermon's debt under this facility. This is a standard step in merger transactions where the acquirer refinances or pays off the target company's existing debt.

On the Closing Date, the Company consummated the Mergers. The Mergers are intended to qualify for U.S. federal income tax purposes as a “reorganization” within the meaning of Section 368(a) of the Internal Revenue Code of 1986, as amended (the “Code”).
Thermon Group Holdings completed its merger with CECO Environmental Corp on June 1, 2026.

In connection with the Second Merger, Thermon requested that the New York Stock Exchange (the "NYSE") file a Form 25 with the SEC to withdraw its common stock from listing on the NYSE and to deregister its common stock under Section 12(b) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”). Thermon’s obligation to file periodic reports under the Exchange Act will be suspended upon the filing of the Form 15 with the SEC.
Thermon's common stock will be delisted from the NYSE and deregistered under the Exchange Act. The company will cease filing periodic SEC reports once Form 15 is filed, as it is now a wholly-owned subsidiary of CECO.

On June 1, 2026, in connection with the consummation of the Mergers, the Company notified the NYSE that the certificates of merger were filed with the Secretary of State of the State of Delaware, in each case, to effect the Mergers.

As a result, trading of Thermon Common Stock, which traded under the ticker symbol “THR” on the NYSE, was suspended prior to the opening of trading on the NYSE on June 1, 2026.
