Todd Gleason, CECO's Chairman and Chief Executive Officer commented: “We delivered an exceptional second quarter, with numerous financial records led by tremendous growth in both orders and backlog. Our multi-year, high-performance growth and value creation model continues to demonstrate the power of our operating model and the growing demand for our leading solutions across diverse global end markets. Additionally, we are pleased to have closed the Thermon acquisition in early June and report that the integration activities are progressing extremely well. Early synergy capture is proceeding ahead of our pre-acquisition integration objectives, and we are driving strong execution across the combined organization.”

Second quarter operating loss was $(33.2) million, compared with operating income of $18.1 million in the prior-year quarter. On an adjusted basis, non-GAAP operating income was $32.1 million, up $13.8 million or 75 percent compared with $18.3 million in the prior-year quarter. Net loss was $(34.8) million in the quarter, compared with net income of $9.5 million in the prior-year quarter. Non-GAAP net income was $21.5 million, an increase of $12.8 million, or 147 percent, from $8.7 million in the prior-year quarter. Adjusted EBITDA was $40.2 million, reflecting a margin of 14.1 percent, an increase of $16.9 million, or 73 percent, compared with $23.3 million in the prior-year quarter. Adjusted free cash flow in the quarter was $53.2 million, an improvement of $56.2 million compared with $(3.0) million in the prior-year quarter.

“Our quarterly results are impressive, and even more so when compared to the then record second quarter results we delivered last year. Our teams continue to deliver outstanding service and solutions to our global customers. The addition of Thermon and their industry-leading technologies and talented workforce helps to expand our record sales pipeline to over $8.5 billion. We expect our sales pipeline will continue to grow as we benefit from organic and inorganic investments to further expand into new markets and introduce new innovations and services. Our most compelling markets are very demanding and require leading partners with expertise and proven solutions. Given our trajectory and ability to invest in future growth, we continue to be confident in our long-term, double-digit growth outlook,” added Gleason.

2026 Full Year Guidance Update

The Company is raising its full-year 2026 outlook as a result of the strong first half performance and record pipeline and backlog. The updated full year consolidated 2026 outlook is:

•

Revenue between $1.300 billion and $1.375 billion, up from $1.275 billion and $1.375 billion • Adjusted EBITDA between $200 million and $225 million, up from $195 million and $225 million • Free cash flow conversion of at least 55 percent of Adjusted EBITDA “Our confidence in our operating model and the robustness of our key growth markets, along with the positive trends from the Thermon integration, allows us to raise our full year outlook. Our third quarter has started very well – with no slowdown in booked projects and sales opportunity discussions proceeding as expected. We continue to monitor the situation in the Middle East as well as certain inflationary items, but we believe we are navigating these challenges with cost actions and solid performance. Our teams do an incredible job every day and as I get to know the Thermon organization it is simply another outstanding addition to our leading portfolio of businesses,” concluded Gleason.

RECONCILIATION OF GAAP TO NON-GAAP MEASURES

(1) includes $9.5 million 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 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 basic and diluted earnings per 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 basic and diluted earnings per 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.

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.
