Todd Gleason, CECO's Chief Executive Officer commented, “We closed the year with our strongest quarter to date, highlighted by order bookings in excess of $300 million, the first time in company history. This performance was primarily driven by a large domestic gas-fired power generation project of approximately $135 million, also a company record in project value. This marks our fifth consecutive quarter with orders above $200 million, underscoring the continued momentum in our core markets as we enter 2026. Revenue of approximately $215 million reflects strong execution against our record and growing backlog, with gross profit margin improving sequentially to 35 percent as we recovered from the seasonal headwinds experienced in the third quarter. Adjusted EBITDA margin of 13.9 percent represents a quarterly record and provides a strong finish to the year. I am also excited to share that today we announced, in a separate press release, a transaction to combine CECO with Thermon – a diversified industrial technology company and a global leader in industrial process heating solutions.”

Fourth quarter operating income was $16.5 million, up $5.2 million or 46 percent when compared to $11.3 million in the fourth quarter 2024. On an adjusted basis, non-GAAP operating income was $24.0 million, up $8.4 million or 54 percent when compared to $15.6 million in the fourth quarter of 2024. Net income was $3.1 million in the quarter, down $1.8 million or 37 percent when compared to $4.9 million in the fourth quarter of 2024. Non-GAAP net income was $11.1 million, up $1.1 million or 12 percent when compared to $9.9 million in the fourth quarter of 2024. Adjusted EBITDA of $29.8 million, reflecting a margin of 13.9 percent, was up 57 percent compared to $19.0 million in the fourth quarter of 2024. Free cash flow in the quarter was $8.7 million, up $13.1 million compared to $(4.4) million in the fourth quarter of 2024.

Full year operating income - including the impact of the sale of our Global Pump Solutions business in March 2025 - was $105.9 million, up $70.5 million in the year, compared to $35.4 million in 2024. On an adjusted basis, non-GAAP operating income was $68.5 million, up $19.1 million in the year, compared to $49.4 million in 2024. Net income was $50.1 million in the year, compared to $13.0 million in 2024. Non-GAAP net income was $32.6 million, compared to $26.7 million in 2024. Adjusted EBITDA of $90.3 million, reflecting a margin of 11.7 percent, was up 44 percent compared to $62.8 million in 2024, reflecting a margin of 11.3 percent. Free cash flow was $9.6 million, up $2.2 million compared to $7.4 million in 2024.

“We delivered another year of outstanding growth with multiple financial records, highlighted by order bookings of approximately $1.1 billion, up 59% year over year. This performance demonstrates the strength of our opportunity pipeline, which now totals approximately $6.5 billion, an increase of 45 percent from year-end 2024,” added Gleason. “Throughout 2025 and as we enter 2026, we delivered on our leadership position in Power Generation markets, which remain robust. We also drove outstanding results across our diversified industrial air and water businesses, which serve attractive end markets such as data centers, semiconductor, and reshoring activities. The sustainability of our organic and inorganic growth and operating model is solidified by the multiple financial records we achieved over the past few years.”

Raises 2026 Full Year Guidance

The Company raises its 2026 full year outlook to reflect revenue between $925 and $975 million, up approximately 25 percent at the midpoint of the range, and Adjusted EBITDA between $115 and $135 million, up approximately 40 percent at the midpoint of the range. The updated outlook compares with the previous guidance of revenues between $850 and $950 million, and Adjusted EBITDA between $110 and $130 million. The Company reiterates its full year free cash flow of at least 50% of Adjusted EBITDA. The current update to the Company’s 2026 outlook excludes the impact of the proposed merger transaction with Thermon.

“We entered 2026 with a record sales pipeline, our largest ever backlog and tremendous bookings momentum. We expect our largest markets will remain strong and we have confidence in our proven operating model that we will execute at a high level. With these inputs, we are increasing our full year outlook – which does not include the positive financial impact of our recently announced proposed merger transaction with Thermon, which we expect will close mid-2026. I want to continue to thank our dedicated employees and partners as we deliver for our global customers while we protect people, the environment and industrial equipment,” concluded Gleason.

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 financial performance that excludes amounts that are included in the most directly comparable measure calculated and presented in accordance with GAAP.

Non-GAAP operating income, non-GAAP net income, non-GAAP operating margin, non-GAAP earnings per basic and diluted share, adjusted EBITDA, and 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 operating income, non-GAAP net income, non-GAAP operating margin, Adjusted EBITDA and 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 operating income, non-GAAP net income, non-GAAP operating margin, non-GAAP earnings per basic and diluted share, adjusted EBITDA and free cash flow stated in the tables above are reconciled to the most directly comparable GAAP financial measures.

Non-GAAP measures presented on a forward-looking basis 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.

These statements are made on the basis of management’s views and assumptions regarding future events and business performance. We use words such as “believe,” “expect,” “anticipate,” “intends,” “estimate,” “forecast,” “project,” “will,” “plan,” “should” and similar expressions to identify forward-looking statements. Forward-looking statements involve risks and uncertainties that may cause actual results to differ materially from any future results, performance or achievements expressed or implied by such statements. Potential risks and uncertainties, among others, that could cause actual results to differ materially are discussed under “Part I – Item 1A. Risk Factors” of the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2025 and may be included in subsequently filed Quarterly Reports on Form 10-Q, and include, but are not limited to: risks related to the proposed transaction with Thermon (the “proposed transaction”), including the expected timing and likelihood of completion of the proposed transaction; the timing, receipt and terms and conditions of any required governmental and regulatory approvals, including the expiration or termination of the applicable waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, that could reduce anticipated benefits or cause the parties to abandon the proposed transaction; the occurrence of any event, change or other circumstances that could give rise to the termination of the merger agreement; the possibility that stockholders of CECO or Thermon may not approve the proposed transaction; the risk that the parties may not be able to satisfy the conditions to the proposed transaction in a timely manner or at all; the risk that any announcements relating to the proposed transaction could have adverse effects on the market price of CECO common stock or Thermon common stock; the risk that the proposed transaction and its announcement could have an adverse effect on the ability of CECO and Thermon to retain customers and retain and hire key personnel and maintain relationships with their suppliers, distributors and customers and on their operating results and businesses generally; the risk that the proposed transaction could distract management of both entities and that they may incur substantial costs; the risk that problems may arise in successfully integrating the businesses of the companies, which may result in the combined company not operating as effectively and efficiently as expected; the risk that the combined company may be unable to achieve expected synergies or other anticipated benefits or it may take longer than expected to achieve those synergies or benefits; and the risk that the combined company's indebtedness may be higher than expected; the effect of other recent acquisitions and the divestiture of our fluid handling business (together with the proposed transaction, the “transactions”) on business relationships, operating results, and business generally; the amount of the costs, fees, expenses and other charges related to such transactions; our ability to successfully integrate acquired businesses and realize the anticipated benefits and synergies from such transactions; the sensitivity of our business to economic and financial market conditions, including changes in interest rates, inflation, geopolitical events, trade policy, tariffs, supply chain disruptions and commodity prices; dependence on fixed price contracts and the risks associated therewith, including actual costs exceeding estimates and method of accounting for revenue; the effect of growth on our infrastructure, resources and existing sales; the ability to expand operations in both new and existing markets; the potential for contract delay or cancellation as a result of on-going or worsening supply chain challenges, or other customer-driven project delays; liabilities arising from faulty services or products that could result in significant professional or product liability, warranty or other claims; changes in or developments with respect to any litigation or investigation; failure to meet timely completion or performance standards that could result in higher cost and reduced profits or, in some cases, losses on projects; the potential for fluctuations in prices for manufactured components and raw materials, including as a result of tariffs and surcharges, and rising energy costs; inflationary pressures relating to rising raw material costs and the cost of labor; the substantial amount of debt incurred in connection with our strategic transactions and our ability to repay or refinance it or incur additional debt in the future; the impact of federal, state or local government regulations, including with respect to tax policy; our ability to repurchase shares of our common stock and the amounts and timing of repurchases, if any; our ability to successfully realize the expected benefits of our restructuring program; our ability to optimize our business portfolio by identifying acquisition targets, executing upon any strategic acquisitions or divestitures, integrating acquired businesses and realizing the synergies from strategic transactions; unpredictability and severity of catastrophic events, including cybersecurity threats, acts of terrorism or outbreak of war or hostilities or public health crises, as well as management's response to any of the aforementioned factors; and our ability to remediate our material weaknesses, or any other material weakness that we may identify in the future, that could result in material misstatements in our financial statements. Many of these risks are beyond management's ability to control or predict. Should one or more of these risks or uncertainties materialize, or should any related assumptions prove incorrect, actual results may vary in material aspects from those currently anticipated. Investors are cautioned not to place undue reliance on such forward-looking statements as they speak only to our views as of the date the statement is made. Except as required under the federal securities laws or the rules and regulations of the Securities and Exchange Commission, we undertake no obligation to update or review any forward-looking statements, whether as a result of new information, future events or otherwise.
