CECO Environmental Completes $2.2 Billion Thermon Acquisition
The deal unites complementary industrial thermal and environmental solutions to target growth in power generation, data centers, and semiconductors.
**CECO Environmental Corp. (CECO)** completed its acquisition of **Thermon Group Holdings, Inc. (THR)**, a diversified industrial technology company specializing in process heating solutions, in a transaction valued at approximately $2.2 billion. The combination creates a scaled platform of mission-critical industrial solutions, integrating Thermon’s thermal capabilities with CECO’s environmental offerings to address secular trends in energy transition, power generation, and industrial reshoring.
Under the merger agreement, Thermon shareholders received a mix of cash and CECO common stock, subject to proration. The consideration structure included $63.89 in cash, 0.8110 shares of CECO stock, or a combination of $10.00 in cash and 0.6840 shares of CECO stock per Thermon share. Preliminary election results showed 41.18% of Thermon shareholders opted for stock, 6.50% for all-cash, and 19.22% for the mixed consideration, with the remainder defaulting to the mixed option. The transaction closed on June 1, 2026, following overwhelming stockholder approval at both companies’ meetings, where nearly 99.9% of votes cast supported the deal.
CECO framed the acquisition as a transformative step to expand its exposure to high-growth markets, including data centers, semiconductors, and industrial reshoring projects. The company expects the deal to generate at least $40 million in annual cost synergies within three years, with integration already underway. "I am pleased to share that approximately one week after closing our acquisition of Thermon, the initial integration phase is on track and delivering immediate benefits," said Todd Gleason, Chairman and Chief Executive Officer of CECO. "Week one activities were positively received by employees, channel partners, customers and investors... Our detailed integration program ensured we experienced no operating challenges and we have already begun to capture cost and growth synergies".
Thermon, headquartered in Austin, Texas, is a global leader in industrial process heating, temperature maintenance, and environmental monitoring solutions, serving industries such as power generation, petrochemical processing, and semiconductor manufacturing. The company’s portfolio includes heat tracing systems, steam and fluid heating solutions, and digital monitoring technologies, which complement CECO’s engineered systems for air quality, emissions control, and industrial water treatment. The combined entity will operate under the CECO Environmental name, with Gleason continuing as CEO and the board expanded to include two former Thermon directors, Victor Richey and Marcus George.
The deal follows a wave of consolidation in the industrial solutions sector, where companies have sought scale to address demand for integrated environmental and thermal technologies. Earlier in 2026, CECO and Thermon announced the transaction in February, positioning it as a platform to capitalize on infrastructure development, decarbonization, and tightening environmental regulations. The combined company projects pro forma revenue of approximately $1.5 billion for calendar year 2026, with adjusted EBITDA margins exceeding 19.5% when synergies are included.
Regulatory and shareholder approvals have been secured, and the companies have begun executing on integration plans. CECO funded the cash portion of the deal through existing credit facilities, while the equity component was issued to Thermon shareholders. The transaction is expected to be significantly accretive to adjusted earnings per share in the first year, with pro forma net leverage targeted below 2.5x. CECO will host a conference call on June 9 to discuss the combination and provide an update on synergy realization.
