Thermon Group Holdings, Inc. 8-K

What Happened

• Thermon Group Holdings, Inc. filed an 8-K on June 1, 2026 announcing that the mergers with CECO Environmental Corp. (the “Mergers”) have closed. CECO issued approximately 22.53 million shares of CECO common stock to former Thermon holders and paid aggregate cash consideration of about $329.4 million. About 32.94 million Thermon shares were outstanding immediately before the First Merger.
• The Mergers were intended to qualify as a tax-free reorganization under Section 368(a) of the Internal Revenue Code. Thermon’s outstanding unsecured credit agreement (the Amended and Restated Credit Agreement dated September 29, 2021, as amended) was fully paid off by CECO on Thermon’s behalf and terminated in connection with the closing.

Key Details

• Merger consideration options per Thermon share at the First Merger: Mixed (0.6840 CECO shares + $10.00), Cash ($63.89), or Stock (0.8110 CECO shares); un-elected shares defaulted to the Mixed Election. Cash for fractional shares based on a five-day Nasdaq average prior to closing.
• CECO issued ~22.53M shares and paid ~$329.4M in cash; Thermon had ~32.94M shares outstanding before the merger.
• Equity awards: outstanding Thermon RSUs were converted to CECO RSUs at a 0.8110 ratio (rounded down); performance units converted and became time‑based RSUs; in‑the‑money Thermon options were canceled for cash equal to $63.89 minus the exercise price (net of tax withholding). CECO expects to file a Form S-8 to register shares for converted RSUs.
• Corporate changes: Thermon requested NYSE delisting and deregistration and will suspend Exchange Act reporting upon filing Form 15; all Thermon directors and executive officers ceased their positions at the effective time of the First Merger.

Why It Matters

• For former Thermon shareholders, the transaction converts Thermon equity into CECO stock and/or cash per election and proration rules, materially changing where value and liquidity reside (now in CECO securities/cash).
• The payoff and termination of Thermon’s credit agreement removes that debt and related covenants from Thermon’s balance sheet at closing, simplifying the combined capital structure.
• Delisting and suspension of SEC periodic reporting means Thermon will stop reporting financials as a standalone public company; ongoing investor focus should shift to CECO’s reporting and the combined company’s performance.
