Todd Gleason, CECO's Chairman and Chief Executive Officer commented: “Our strong third quarter results reflect CECO’s leadership in attractive and growing niche markets across a range of resilient industrial end markets. Customers around the world rely on our solutions and expertise to meet or exceed critical environmental and process safety requirements. Our sustainable growth is a testament to the strength of our incredible portfolio, the dedication of our employees, and the support of our global partners. We have a proven track record of creating value for our customers, partners, communities and our shareholders. While recent headlines and U.S. election developments have created volatility in equity markets, which we certainly monitor, we remain focused on the factors within our control. The continued visibility we have in our $2.2 billion backlog – the vast majority of which is permitted and underway, our rapidly growing $9 billion sales pipeline, and our productivity and synergy initiatives reinforce my confidence in our strategy and my conviction in our ability to deliver significant long-term value creation.”

Third quarter operating income was $10.5 million, compared with operating income of $9.4 million in the prior-year quarter. On an adjusted basis, non-GAAP operating income was $55.7 million, up $38.2 million or 218 percent compared with $17.5 million in the prior-year quarter. Net loss was $(2.0) million in the quarter, compared with net income of $1.5 million in the prior-year quarter. Non-GAAP net income was $34.3 million, an increase of $25.0 million, or 269 percent, from $9.3 million in the prior-year quarter. Adjusted EBITDA was $70.1 million, reflecting a margin of 17.3 percent, an increase of $46.9 million, or 202 percent, compared with $23.2 million in the prior-year quarter. Adjusted free cash flow in the quarter was $154.4 million, an improvement of $135.4 million compared with $19.0 million in the prior-year quarter.

“Since closing the Thermon acquisition in June, we have substantially completed key integration initiatives. We remain ahead of schedule on both our cost and revenue synergies, and the combination is an excellent cultural fit. Across our entire CECO portfolio, we continue to see strong momentum driven by growth across our diverse end markets, increasing customer demand, and the continued execution of our operational initiatives, which are contributing to margin expansion and enhanced cash flow generation. Our proven operating model has delivered regular double-digit growth and meaningful margin expansion since 2021, and I expect will continue to drive strong performance in 2027 and 2028. While we are pleased to have delivered more than 100 percent revenue growth and over 200 percent growth in orders, backlog and Adjusted EBITDA during the third quarter, we are even more excited about the future. The strategic investments we have made to strengthen and expand our industrial leadership into new markets position us to drive even higher levels of performance in the years to come,” added Gleason.

2026 Full Year Guidance Update

The Company is updating its full-year 2026 outlook as a result of the strong year-to-date performance and near-term market opportunities. The updated full year consolidated 2026 outlook is:

•

Raising full year Orders to exceed $2.5 billion, compared to previous outlook of at least $2.0 billion • Raising full year free cash flow conversion to approximately 100 percent of Adjusted EBITDA, compared to previous outlook of at least 55 percent • Maintaining full year Revenue outlook of between $1.300 billion and $1.375 billion • Maintaining full year Adjusted EBITDA outlook of between $200 million and $225 million “As we work to conclude another banner year at CECO, we expect to deliver results at or above the full year guidance we have raised multiple times throughout the year, including the most recent increase in August. The projects in our backlog remain largely on schedule, and our sales pipeline continues to expand in both size and quantity. While we anticipate additional orders to be realized in power markets, I would emphasize that demand for our environmental, industrial and thermal solutions remain equally robust and often are realized later in the project supply chain cycle and generally represent funded, active projects rather than speculative demand,” added Gleason.

Introducing 2027 Full Year Outlook

The Company introduces its 2027 full year outlook with revenue expected to be between $2.1 billion and $2.3 billion, representing growth of more than 60 percent at the midpoint compared with the midpoint of the Company’s 2026 revenue outlook, and Adjusted EBITDA between $475 million and $525 million, representing growth of more than 130 percent at the midpoint compared with the midpoint of the Company’s 2026 Adjusted EBITDA outlook. The Company expects full year free cash flow of between 50 percent and 60 percent of Adjusted EBITDA.

Mr. Gleason concluded, “CECO continues to transform and drive high-performance thanks to our incredible teams executing at high levels and generating incredible returns on our growth and operating improvement investments. Our full year 2027 outlook highlights further growth and scale. Since introducing our annual guidance process back in Q3 2021, we have a solid track record of meeting or exceeding our outlook as we incorporate significant backlog and pipeline insights, conservative assumptions on inflation and key market dynamics. The combination of our proven process and consistent track record, along with our visibility into our backlog and sales pipeline, gives us high confidence that 2027 will be another rewarding year for all our stakeholders.”

RECONCILIATION OF GAAP TO NON-GAAP MEASURES

(1) includes $16.7 million and $26.2 million for the three and nine months ended September 30, 2026, respectively, related to the purchase accounting inventory valuation adjustment

NOTE REGARDING NON-GAAP FINANCIAL MEASURES

CECO is providing certain non-GAAP historical financial measures as presented above as we believe that these figures are useful to investors and management in evaluating the Company's ongoing financial performance, and we believe that they provide greater transparency to investors as supplemental information to its GAAP results. A "non-GAAP financial measure" is a numerical measure of a company's historical or future financial performance, financial position, or cash flows that includes or excludes amounts from the most directly comparable measure calculated and presented in accordance with GAAP.

Non-GAAP gross profit, non-GAAP gross margin, non-GAAP operating income, non-GAAP net income, non-GAAP operating margin, non-GAAP basic and diluted earnings per share, Adjusted EBITDA, free cash flow, and adjusted free cash flow as presented in the financial data included in this press release, have been adjusted to exclude the effects of acquisition and integration expenses; divestiture gains and expenses; amortization expenses for acquisition-related intangible assets; earn-out expenses (income); restructuring expenses; executive transition expenses; asbestos and other legal matter expenses; foreign currency remeasurement; and the associated tax benefit or cost of these items. Management believes that these items are not necessarily indicative of the Company’s ongoing operations and their exclusion provides individuals with additional information to better compare the Company's results over multiple periods. Management utilizes this information to evaluate its ongoing financial performance. Our financial statements may continue to be affected by items similar to those excluded in the non-GAAP adjustments described above, and exclusion of these items from our non-GAAP financial measures should not be construed as an inference that all such costs are unusual or infrequent.

Non-GAAP gross profit, non-GAAP gross margin, non-GAAP operating income, non-GAAP net income, non-GAAP operating margin, Adjusted EBITDA, free cash flow, and adjusted free cash flow are not calculated in accordance with GAAP, and should be considered supplemental to, and not as a substitute for, or superior to, financial measures calculated in accordance with GAAP. Non-GAAP financial measures have limitations in that they do not reflect all of the costs associated with the operations of our business as determined in accordance with GAAP. As a result, you should not consider these measures in isolation or as a substitute for analysis of CECO’s results as reported under GAAP. Additionally, CECO cautions investors that non-GAAP financial measures used by the Company may not be comparable to similarly titled measures of other companies.

In accordance with the requirements of Regulation G issued by the Securities and Exchange Commission, non-GAAP gross profit, non-GAAP gross margin, non-GAAP operating income, non-GAAP net income, non-GAAP operating margin, non-GAAP basic and diluted earnings per share, Adjusted EBITDA, free cash flow, and adjusted free cash flow stated in the tables above are reconciled to the most directly comparable GAAP financial measures.

Forward-looking non-GAAP financial measures, including Adjusted EBITDA and free cash flow included in the Company’s 2026 and 2027 outlook, were not reconciled to the comparable GAAP financial measures because the reconciliation could not be performed without unreasonable efforts. The GAAP measures are not accessible on a forward-looking basis because we are currently unable to predict with a reasonable degree of certainty the type and extent of certain items that would be expected to impact GAAP measures for these periods but would not impact the non-GAAP measures. Such items may include acquisition and integration expenses; divestiture gains and expenses; amortization expenses for acquisition-related intangible assets; earn-out expenses (income); restructuring expenses; executive transition expenses; asbestos and other legal matter expenses; foreign currency remeasurement; and the associated tax benefit or cost of these items.
