CECO ENVIRONMENTAL CORP

1. Basis of Reporting for Consolidated Financial Statements

The accompanying unaudited condensed consolidated financial statements of CECO Environmental Corp. and its subsidiaries (the “Company,” “CECO,” “we,” “us,” or “our”) have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission (the “SEC”). Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) have been condensed or omitted pursuant to those rules and regulations. In the opinion of management, the accompanying unaudited condensed consolidated financial statements of the Company contain all adjustments, consisting only of normal recurring adjustments, necessary to present fairly the financial position as of June 30, 2026 and the results of operations, cash flows and shareholders’ equity for the three and six months ended June 30, 2026 and 2025. The results of operations for the three and six months ended June 30, 2026 are not necessarily indicative of the results to be expected for the full year. The balance sheet as of December 31, 2025 has been derived from the audited consolidated financial statements included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2025 as filed with the SEC on March 2, 2026 (the “Form 10-K”). Certain prior period amounts were reclassified to conform to the presentation in the current period.

During the three months ended June 30, 2026, the Company completed the acquisition of Thermon Group Holdings ("Thermon"), as discussed in Note 14. As a result, Thermon's assets, liabilities, and results of operations have been included in the Company's condensed consolidated financial statements commencing on the acquisition date.

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

These financial statements and accompanying notes should be read in conjunction with the audited financial statements and the notes thereto included in the Form 10-K.

Unless otherwise indicated, all balances within tables are in thousands, except per share amounts.

2. Recent Financial Accounting Pronouncements

The Company considered the impact of all Accounting Standards Updates ("ASUs") issued by the Financial Accounting Standards Board ("FASB"). The ASUs issued but not listed below were assessed and determined to be either not applicable or are expected to have minimal impact on the Company's consolidated financial statements.

Accounting Standards Adopted in Fiscal 2026

Effective January 1, 2026, the Company adopted ASU 2025-05, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses for Accounts Receivable and Contract Assets, which introduces a practical expedient for estimating credit losses on current accounts receivable and contract assets. Adoption did not have a material impact on the Company's condensed consolidated financial statements.

Accounting Standards to be Adopted

In September 2025, the FASB issued ASU 2025-06, Intangibles - Goodwill and Other - Internal-Use Software (Subtopic 350-40): Targeted Improvements to the Accounting for Internal-Use Software, which removes references to project stages, and requires capitalization of software costs to begin when management has authorized and committed to funding the software project, and it is probable that the project will be completed and the software will be used to perform the intended function. The ASU is effective for fiscal years beginning after December 15, 2027, and interim periods within those annual reporting periods. The Company is currently evaluating the impact the adoption of the standard will have on the Company’s consolidated financial statements.

In November 2024, the FASB issued ASU 2024-03, Income Statement—Reporting Comprehensive Income—Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses, which addresses expense disclosure requirements, primarily the disaggregation of expense captions. The ASU is effective for fiscal years beginning after

December 15, 2026, and interim periods beginning after December 15, 2027. The Company is currently evaluating the impact the adoption of the standard will have on the Company’s consolidated financial statements.

6. Goodwill and Intangible Assets

Goodwill and indefinite life intangible asset activity for thesix months ended June 30, 2026 and the year ended December 31, 2025 was as follows:

During the three months ended March 31, 2026, the Company, through its Pinnacle Processes Inc. ("PPI") (formerly known as Effox-Flextor-Mader, Inc.) joint venture, completed the acquisition of Flexible Specialty Products ("FSP"), as discussed in Note 14.

During the three months ended June 30, 2026, the Company completed the acquisition of Thermon Group Holdings ("Thermon"), as discussed in Note 14.

Finite life intangible assets as of June 30, 2026 and December 31, 2025 consisted of the following:

Finite life intangible asset activity for thesix months ended June 30, 2026 and 2025 was as follows:

In the second quarter of 2026, the Company shut down its Western Air Ducts business located in the United Kingdom. As a result, the Company recorded an impairment charge of $1.7 million related to finite life intangible assets. This was recorded to "'Other operating expense (income)" on the Condensed Consolidated Statements of Operations. In the first quarter of 2025, the Company completed the divestiture of its Global Pump Solutions business, and recognized $4.0 million related to the removal of the net book value of its intangible assets. This was recorded to "Gain on sale of Global Pump Solutions business" on the Condensed Consolidated Statements of Operations.

Amortization expense of finite life intangible assets was$7.8 million and$2.9 million for the three months ended June 30, 2026 and 2025, respectively, and$11.8 million and$6.0 million for the six months ended June 30, 2026 and 2025, respectively. Amortization over the next five years for finite life intangibles is expected to be$28.9 million for the remainder of 2026,$70.9 million in 2027,$68.2 million in 2028,$63.5 million in 2029,$62.7 million in 2030, and$705.2 million thereafter. The weighted average amortization periods for finite life intangible assets was 20.3 years as of June 30, 2026, inclusive of weighted average amortization periods for technology, customer lists, and tradenames and other of 19.4,21.6, and 18.8 years, respectively.

Annually during the fourth quarter, or more often as circumstances require, the Company completes an impairment assessment of its goodwill and indefinite life intangible assets at the reporting unit level. As a part of its annual assessment, the Company first qualitatively assesses whether current events or changes in circumstances lead to a determination that it is more likely than not, defined as a likelihood of more than 50 percent, that the fair value of a reporting unit is less than its carrying amount. If there is a qualitative determination that the fair value of a particular reporting unit is more likely than not greater than its carrying value, the Company does not need to quantitatively test for impairment for that reporting unit. If this qualitative assessment indicates a more likely than not potential that the asset may be impaired, the estimated fair value is determined using a weighting of the income method and the market method. If the estimated fair value of a reporting unit is less than its carrying value, an impairment charge is recorded.

Additionally, property, plant and equipment, right-of-use assets, and finite life intangible assets are reviewed whenever events or changes in circumstances occur that indicate possible impairment. If events or changes in circumstances occur that indicate possible impairment, the impairment review is based on an undiscounted cash flows analysis at the lowest level at which cash flows of the long-lived assets are largely independent of other groups of assets and liabilities. When impairment is indicated, the estimated future cash flows are then discounted to determine the estimated fair value of the asset or asset group and an impairment charge is recorded for the difference between the carrying value and the estimated fair value.

The Company did not identify any other triggering events that would require an interim impairment assessment, or record an additional impairment of goodwill, indefinite life intangible assets, finite life intangible assets, right-of-use assets, or property, plant and equipment during the three or six months ended June 30, 2026, other than as related to the Western Air Ducts business as discussed above.

The Company’s assumptions about future conditions important to its assessment of potential impairment are subject to uncertainty, and the Company will continue to monitor these conditions in future periods as new information becomes available and will update its analysis accordingly.

9. (Loss) Earnings per Share

The computational components of basic and diluted (loss) earnings per share for the three months ended June 30, 2026 and 2025 are as follows:

The computational components of basic and diluted (loss) earnings per share for the six months ended June 30, 2026 and 2025 are as follows:

Options and restricted stock units included in the computation of diluted earnings per share are calculated using the treasury stock method. For each of the three months ended June 30, 2026 and 2025, zero and 0.2, and for the six months ended June 30, 2026 and 2025, zero million and 0.3 million, respectively, of outstanding options and restricted stock units were excluded from the computation of diluted earnings per share due to their having an anti-dilutive effect. For the three and six months ended June 30, 2026, the Company had a net loss. As a result, no potentially dilutive shares were included in the computation, as their inclusion would have been anti-dilutive. The shares that could potentially dilute earnings per share in the future were 2.0 million and 2.0 million for the three and six months ended June 30, 2026.

Once a restricted stock unit vests, it is included in the computation of weighted average shares outstanding for purposes of basic and diluted earnings per share.

Common Stock Repurchase

On May 10, 2022, the Company's Board of Directors authorized a share repurchase program under which the Company was able to purchase up to $20.0 million of its outstanding shares of common stock through April 30, 2025. The authorization permitted the Company to repurchase shares in the open market, through accelerated share repurchases, block trades, Rule 10b5-1 trading plans or through privately negotiated transactions in accordance with applicable laws, rules and regulations. There wereno shares repurchased under the program during the three orsix months ended June 30, 2025. This program expired during the second quarter of 2025.

10. Share-Based Compensation

The Company recognized$12.4 million and$2.9 million of expense related to share-based compensation during the three months ended June 30, 2026 and 2025, respectively, and$12.8 million and$6.2 million during the six months ended June 30, 2026 and 2025, respectively, which was measured based upon the fair value of the awards at the grant date. Included in current period expense was $8.5 million of share-based compensation expense recognized in connection with the accelerated vesting of certain legacy Thermon equity awards triggered by the acquisition. This was recorded to "Acquisition and integration expense" on the Condensed Consolidated Statements of Operations.

The Company granted approximately 25,243 and 203,000 restricted stock units during the three months ended June 30, 2026 and 2025, respectively, and approximately 251,712 and 590,000 restricted stock units during the six months ended June 30, 2026 and 2025, respectively. In addition, the Company granted 17,563 and 67,000 stock options during the six months ended June 30, 2026 and 2025, respectively.

11. Income Taxes

The Company files income tax returns in various federal, state and local jurisdictions. Tax years from 2021 forward remain open for examination by Federal authorities. Tax years from 2018 forward remain open for all significant state and foreign authorities.

As of June 30, 2026 and December 31, 2025, the liability for uncertain tax positions totaled approximately$1.4 million and$1.3 million, respectively, which is included in “Other liabilities” on the Condensed Consolidated Balance Sheets. The Company recognizes accrued interest related to uncertain tax positions and penalties, if any, in income tax expense within the Condensed Consolidated Statements of Operations.

Certain of the Company’s undistributed earnings of our foreign subsidiaries are not permanently reinvested. Since foreign earnings have already been subject to United States income tax in 2017 as a result of the 2017 Tax Cuts and Jobs Act, the Company intends to repatriate foreign-held cash as needed. The Company records deferred income tax attributable to foreign withholding taxes that would become payable should it decide to repatriate cash held in our foreign operations. As of June 30, 2026 and December 31, 2025, the Company recorded deferred income taxes of approximately$1.7 million and$1.1 million, respectively, on the undistributed earnings of its foreign subsidiaries.

Income tax benefit was$10.1 million for the three months ended June 30, 2026, compared with income tax expense of$4.5 million for the three months ended June 30, 2025. Income tax benefit was$13.6 million for the six months ended June 30, 2026 compared with income tax expense of$23.1 million for the six months ended June 30, 2025. The effective income tax rate for the three months ended June 30, 2026 was 22.6% compared with 30.9% for the three months ended June 30, 2025, and the effective income tax rate for the six months ended June 30, 2026 was 28.1% compared with 33.2% for the six months ended June 30, 2025. The effective income tax rates for the three and six months ended June 30, 2026 and 2025 differ from the United States federal statutory rate due to certain other permanent differences, including the gain on the sale of the Global Pump Solutions business, state income taxes, non-deductible incentive stock-based compensation and differences in tax rates among jurisdictions in which it operates.

The Organization for Economic Co-operation and Development/G20 Inclusive Framework on Base Erosion and Profit Shifting published the Pillar Two model rules designed to address the tax challenges arising from the digitalization of the global economy which introduces a 15% global minimum corporate tax for companies with revenues above €750 million calculated on a country-by-country basis. On February 1, 2023, the FASB indicated that it believes the minimum tax imposed under Pillar Two is an alternative minimum tax, and, accordingly, deferred tax assets and liabilities associated with the minimum tax would not be recognized or adjusted for the estimated future effects of the minimum tax but would be recognized in the period incurred. Aspects of Pillar Two legislation have been enacted in certain jurisdictions in which the Company operates effective for accounting periods commencing on or after January 1, 2024. Historically, the Company has not met the Pillar Two revenue threshold. With the acquisition of Thermon, the combined Company will meet the Pillar Two threshold in 2026. The Company expects to meet the Transitional Country-by-Country Safe Harbor rules.

12. Financial Instruments

The Company's financial instruments consist primarily of investments in cash and cash equivalents, receivables and certain other assets, notes payable, and accounts payable, which approximate fair value at June 30, 2026 and December 31, 2025, due to their short-term nature or variable, market-driven interest rates.

The fair value of the debt issued under the Credit Facility and joint venture term loan was$736.7 million and$214.2 million at June 30, 2026 and December 31, 2025, respectively. The fair value was determined considering market conditions, the Company's credit worthiness and the current terms of our debt, which is considered Level 2 on the fair value hierarchy.

At June 30, 2026 and December 31, 2025, the Company had cash and cash equivalents of$61.1 million and$33.1 million, respectively, of which$49.1 million and$26.4 million, respectively, was held outside of the United States, principally in China, Canada, India, Netherlands, United Arab Emirates, and United Kingdom.

13. Commitments and Contingencies

Legal Proceedings

The Company is subject to routine legal claims, proceedings, and investigations associated with contract and employment-related litigation matters, warranty claims, asbestos matters, and audits of state and local tax returns arising in the ordinary course of its business. Following the acquisition of Thermon on June 1, 2026, the Company has also assumed responsibility for legal matters associated with Thermon’s historical operations; however, none of such matters are believed to be material to the Company’s consolidated financial condition, results of operations, or liquidity. The final outcome and impact of open matters, and related claims and investigations that may be brought in the future, are subject to many variables, and cannot be predicted. The Company regularly assesses such matters to determine the degree of probability that it will incur a material loss as a result of such matters, as well as the range of possible loss. The Company records accruals for estimated losses relating to claims and lawsuits when available information indicates that a loss is probable and the amount of the loss, or range of loss, can be reasonably estimated.

Based upon information presently available, and in light of legal and other factual defenses available to the Company, the Company does not believe that it is reasonably possible that such litigation will have a material adverse effect on the Company’s financial condition, future operating results or liquidity.

14. Acquisitions

Thermon Group Holdings, Inc.

On June 1, 2026 (the “Closing Date”), the Company completed its merger (the "Merger") with Thermon Group Holdings, Inc. (“Thermon”), pursuant to the Agreement and Plan of Merger (the “Merger Agreement”) dated February 23, 2026, entered into by the Company with Longhorn Merger Sub, Inc. and Longhorn Merger Sub LLC, each a direct wholly owned subsidiary of the Company (together, the “Merger Subs”) and Thermon. Pursuant to the Merger Agreement, on the Closing Date, Merger Sub Inc. merged with and into Thermon (the “First Merger”), with Thermon surviving the First Merger as a wholly owned subsidiary of CECO. Immediately after the First Merger, Thermon merged with and into Merger Sub LLC (the “Second Merger”), with Merger Sub LLC surviving the Second Merger as a wholly owned subsidiary of CECO. In connection with the Second Merger, the name of the surviving entity was changed to Thermon Group Holdings, LLC. The First Merger and the Second Merger are collectively referred to as the “Merger.”

The Merger was accounted for as a business combination under ASC 805 Business Combinations, with the Company identified as the accounting acquirer. Concurrently with the execution of the Merger Agreement, on February 23, 2026, the Company entered into the financing (as further described in Note 8), which was also completed on June 1, 2026.

Under the terms of the Merger Agreement, each holder of Thermon common stock ("Thermon Common Stock", and "Thermon Shareholders") had the ability to elect to receive, for each share of Thermon Common Stock they own, one of the following forms of consideration: (i) consideration consisting of $10.00 in cash and 0.6840 sharesof CECO common stock (“Mixed

Consideration”),(ii) consideration of $63.89 per share (“All-Cash Consideration”), or (iii) consideration of 0.8110 shares of CECO common stock per share (“All-Stock Consideration”), in each case subject to proration and allocation procedures designed to ensure that the aggregate amount of cash and stock paid in the transaction does not exceed certain limits specified in the Merger Agreement. Thermon Shareholders who did not make an election received the Mixed Consideration. The share value of the Mixed, All-Cash Consideration, and All-Stock Consideration are all approximately $64, based on the closing stock price of $79.03 per share of CECO on June 1, 2026, which represents an approximate 4.7% premium to the closing stock price of $61.14 per share of Thermon on its last day of trading on May 29, 2026. Per the Merger Agreement, Thermon’s existing restricted stock units (“RSU Awards”) and performance unit awards (“PU Awards”) were assumed by the Company and converted into awards based on the Company's common stock, while in‑the‑money stock options (“In-the-Money Options”) were cancelled in exchange for cash consideration equal to the All-Cash Consideration less the exercise price per share of Thermon Common Stock subject to the In-the-Money Options, as of immediately prior to the closing (the “Option Consideration”), and out‑of‑the‑money options were cancelled for no consideration. Under the provisions of the Merger Agreement, the Company elected to cancel the RSU Awards and PU Awards held by individuals residing or providing services outside the U.S. at closing (“Non-U.S. Award”), and pay cash consideration equal to the number of underlying shares multiplied by the per‑share All-Cash Consideration (“Non-U.S. Award Cash Consideration”). The following table summarizes the fair value of consideration transferred for the Merger:

The purchase price was allocated, on a preliminary basis, among assets acquired and liabilities assumed based on available information. The determination of the estimated fair value of assets acquired requires management’s judgment and often involves the use of significant estimates and assumptions, including assumptions with respect to future cash inflows and outflows, discount rates, royalty rates, customer attrition rates, asset lives, and market multiples, among other items. Fair values were determined by management using a variety of methodologies and resources, including external independent valuation experts. The valuation methods consisted of multi-period excess earnings, relief from royalty, current replacement cost, and other valuation techniques to determine the fair value of assets acquired and liabilities assumed.

The Company preliminarily recognized fair values of the assets acquired and liabilities assumed and allocated $1,210.5 million to goodwill. Goodwill primarily represents expected synergies from combining operations, expanded market opportunities, acquired workforce, future technologies, and other benefits that do not qualify for separate recognition. Goodwill is not expected to be deductible for income tax purposes.

The preliminary allocation of the purchase price is subject to change as the Company continues to obtain and assess relevant information that existed as of the acquisition date. A final determination of the fair value of assets acquired, including any identifiable intangible assets, and liabilities assumed will be performed within one year of the Closing Date. The preliminary allocation of the total estimated purchase consideration is as follows:

Acquired intangible assets consisted of the following:

Acquired intangible assets are amortized on a straight line or accelerated basis over their estimated useful lives of approximately 20 years for technology,20 to 25 years for customer lists,20 years for tradenames, and 3 yearsfor customer backlog. From the

June 1, 2026 Closing Date through June 30, 2026, Thermon accounted for$49.6 million in revenue, and$5.3 million in net loss, in the Company's results. Thermon's net loss includes the impact of $3.6 million of intangible amortization from the Closing Date through June 30, 2026, as well as a $9.5 million charge related to the recognition of costs stemming from the step up of fair value of inventory.

Total acquisition-related costs related to the Thermon acquisition of $22.6 million and $34.3 million were reported in"Acquisition and integration expense" on the Condensed Consolidated Statements of Operations for the three and six months ended June 30, 2026.

The Company incurred approximately $8.9 million of acquisition-related costs associated with executive transition and separation arrangements for certain legacy Thermon executives in connection with the acquisition. These costs were recorded within "Acquisition and other integration expenses" in the Condensed Consolidated Statements of Operations.

Flexible Specialty Products LLC

On February 13, 2026, the Company, through its PPI JV, completed its acquisition of FSP for $6.8 million in cash. The transaction was financed through cash on hand. As additional consideration in the acquisition of FSP, the former owners of FSP are also entitled to earn-out payments up to $4.0 million based upon specified financial results through December 31, 2029. Based on projections at the acquisition date, the Company estimated the fair value of the earn-out to be $3.3 million. FSP is a custom manufacturer and supplier of industrial fabric expansion joints, metal bellows, metal hose, and other specialty flexible connectors for ductwork and piping with its primary operations in Englewood, Florida and is reported within the Engineered Systems segment. The following table summarizes the preliminary fair values of the assets acquired and liabilities assumed at the date of closing.

The Company acquired customer lists intangible assets valued at $6.1 million. This asset was determined to have a useful life of 10 years.

During the three and six months ended June 30, 2026, FSP accounted for$1.4 million and$1.8 million in revenue, respectively, and$0.5 million and$0.7 million in net income, respectively, in the condensed consolidated results.

Profire Energy, Inc.

On January 3, 2025, the Company acquired all outstanding shares of Profire for $122.7 million in cash, including $4.6 million of cash used to settle outstanding equity awards for which $2.3 million represents the acceleration of such awards and thus recorded within "Acquisition and integration expenses" on the Condensed Consolidated Statements of Operations. Resulting consideration transferred for the acquisition was $120.4 million. The transaction was financed through a combination of cash on hand and a draw on the Company's revolving credit facility. Profire is a technology company and provider of intelligent control solutions that enhance the efficiency, safety, and reliability of industrial combustion appliances. The business operates primarily from locations in Lindon, Utah and Acheson, Alberta and is reported within the Engineered Systems segment. The following table summarizes the preliminary fair values of the assets acquired and liabilities assumed at the date of closing.

The Company acquired property and equipment consisting of $14.7 million of land, building and improvements, $2.1 million of vehicles, and $0.6 million of machinery and equipment and other.

The Company acquired technology, customer lists, and tradename intangible assets valued at $3.6 million, $34.5 million, and $3.7 million, respectively. These assets were determined to have useful lives of 7,10, and 10 years, respectively.

The acquisitions disclosed above, with the exception of Profire, are subject to final adjustment, primarily for the valuation of intangible assets pending final valuation results for such assets and tax balances for the further assessment of the acquiree’s tax positions. These preliminary estimates and assumptions could change significantly during the purchase price measurement period as the Company finalizes the valuation of assets acquired and liabilities assumed. These changes could result in material variances in the Company's future financial results, including variances in the estimated purchase price, fair values recorded and expenses associated with these items.

Goodwill recognized represents value the Company expects to be created by combining the various operations of the acquired businesses with the Company’s operations, including the expansion into markets within existing business segments, access to new customers and potential cost savings and synergies. Goodwill related to these acquisitions is not deductible for tax purposes. Acquisition and integration expenses, recorded within "Other operating expenses" on the Condensed Consolidated Statements of Operations are related to acquisition activities, which include retention, legal, accounting, banking, and other expenses.

The unaudited supplemental pro forma information is based on estimates and assumptions that the Company believes are reasonable and reflects the effects of the Thermon acquisition and related financing, including the recognition of certain cost of sales and acquired intangible assets, depreciation of acquired property, plant and equipment, amortization of the prepaid directors' and officers' ("D&O") liability insurance tail policy required under the Merger Agreement, incremental share-based compensation expense associated with the conversion and cash settlement of Thermon equity awards, and incremental interest expense, including the amortization of deferred financing costs. Material, nonrecurring pro forma adjustments directly attributable to the Thermon acquisition include transaction costs of $34.3 million that were incurred during the six months ended June 30, 2026, which are assumed to have occurred on the pro forma closing date of January 1, 2025 and recognized as if incurred in the first quarter of 2025.

The unaudited supplemental pro forma information is presented for informational purposes only and does not purport to represent what the Company's results of operations would have been had the acquisition of Thermon and the related financing occurred on January 1, 2025, nor is it necessarily indicative of future operating results.
