CECO and Thermon shareholders overwhelmingly approve strategic combination

CECO Environmental  (NASDAQ:CECO) and Thermon Group Holdings (NYSE:THR) secured near-unanimous approval from their respective stockholders for their pending strategic combination, clearing the final major execution hurdle toward building a consolidated industrial environmental and process thermal solutions provider.

At the separate special shareholder meetings, the transaction proposals passed by decisive margins.

Approximately 99.93% of the votes cast by CECO stockholders were in favor of the business combination, while Thermon stockholders approved the deal with 99.97% of votes cast in support of the merger parameters.

The transaction is expected to officially close on or around June 1, 2026, subject to the final completion of remaining customary closing conditions.

Upon closing, the unified enterprise will integrate CECO’s environmental systems footprint—which addresses air quality, emissions management, and water treatment markets—with Thermon’s global leadership in industrial process heating and temperature maintenance infrastructure.
