Basis of Reporting for Consolidated Financial Statements	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, 2024 and the results of operations, cash flows and shareholders’ equity for the three and six months ended June 30, 2024 and 2023. The results of operations for the three and six months ended June 30, 2024 are not necessarily indicative of the results to be expected for the full year. The balance sheet as of December 31, 2023 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, 2023 as filed with the SEC on March 5, 2024 (the “Form 10-K”). 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.

The Company completes its goodwill and indefinite life intangible asset impairment assessment annually in the fourth quarter, or more often if circumstances require. As a part of its impairment 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 or indefinite life intangible asset is less than its carrying amount. If there is a qualitative determination that the fair value is more likely than not greater than the carrying value, the Company does not quantitatively test for impairment. If this qualitative assessment indicates a more likely than not potential that the asset may be impaired, the estimated fair value is calculated. If the estimated fair value is less than carrying value, an impairment charge is recorded. As of June 30, 2024, the Company reviewed its previous forecasts and assumptions based on its current projections, which are subject to various risks and uncertainties, including projected revenue, projected operational profit, terminal growth rates, and the cost of capital. The Company did not identify any triggering events during the three or six months ended June 30, 2024 that would require an interim impairment assessment of goodwill or intangible assets. The Company’s assumptions about future conditions important to its assessment of potential impairment of its goodwill and indefinite life intangible assets 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.

Revolving loans may be borrowed, repaid and reborrowed until December 17, 2026, at which time all outstanding balances of the Credit Facility must be repaid. At the Company’s option, revolving loans and the term loans accrue interest at a per annum rate based on (a) either the highest of (i) the federal funds rate plus 0.5 %, or (ii) the prime lending rate of the Agent (as defined in the Credit Facility), (b) Daily Simple SOFR plus the Daily Simple SOFR Adjustment of 0.11 % plus 1.0%, (c) 1.0%, plus a margin ranging from 1.75 % to 3.25 % depending on the Company’s Consolidated Leverage Ratio, or (d) a one/three/six-month Term SOFR Rate (as defined in the Credit Facility) plus the Term SOFR Adjustment ranging from 0.11 % to 0.43 % p lus 1.75 % to 3 .25 % depending on the Company’s Consolidated Leverage Ratio.

Income Taxes	12. Income Taxes The Company files income tax returns in various federal, state and local jurisdictions. Tax years from 2018 forward remain open for examination by Federal authorities. Tax years from 2017 forward remain open for all significant s tate and foreign authorities. The Company accounts for uncertain tax positions pursuant to ASC Topic 740, “Income Taxes.” As of June 30, 2024 and December 31, 2023, the liability for uncertain tax positions totaled approximately $ 0.2 million, 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 Income. 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, 2024 and December 31, 2023, the Company recorded deferred income taxes of approximately $ 0.8 million and $ 0.7 million, respectively, on the undistributed earnings of its foreign subsidiaries. Income tax expense was $ 0.4 million and $ 1.0 million for the three months ended June 30, 2024 and 2023, respectively, and $ 1.1 million and $ 1.0 million for the six months ended June 30, 2024 and 2023, respectively. The effective income tax rate for the three months ended June 30, 2024 was 7.4 % compared with 19.8 % for the three months ended June 30, 2023, and the effective income tax rate for the six months ended June 30, 2024 was 13.1 % compared with 13.3 % for the six months ended June 30, 2023. The effective income tax rates for the three and six months ended June 30, 2024 and 2023 differ from the United States federal statutory rate. The Company's effective rate is affected by certain other permanent differences, including state income taxes, non-deductible incentive stock-based compensation and differences in tax rates among jurisdictions in which it operates. Additionally, the Company received a tax indemnification payment of $ 0.5 million, related to a prior year acquisition, in the second quarter of 2024. 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. However, based on the current revenue threshold, the Company is currently not subject to Pillar Two taxes.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies - Legal Matters	14. Commitments and Contingencies Asbestos cases The Company's subsidiary, Met-Pro Technologies LLC (“Met-Pro”), beginning in 2002, has been named in asbestos-related lawsuits filed against a large number of industrial companies including, in particular, those in the pump and fluid handling industries. In management’s opinion, the complaints typically have been vague, general and speculative, alleging that Met-Pro, along with the numerous other defendants, sold unidentified asbestos-containing products and engaged in other related actions which caused injuries (including death) and loss to the plaintiffs. Counsel has advised that more recent cases typically allege more serious claims of mesothelioma. The Company’s insurers have hired attorneys who, together with the Company, are vigorously defending these cases. Many cases have been dismissed after the plaintiff fails to produce evidence of exposure to Met-Pro’s products. In those cases, where evidence has been produced, the Company’s experience has been that the exposure levels are low and the Company’s position has been that its products were not a cause of death, injury or loss. The Company has been dismissed from or settled a large number of these cases. Cumulative settlement payments from 2002 through June 30, 2024 for cases involving asbestos-related claims were $ 6.8 million which together with all legal fees other than corporate counsel expenses have substantially been paid by the Company’s insurers. The average cost per settled claim, excluding legal fees, was approximately $ 33,000 . As of June 30, 2024 and December 31, 2023, the amount recorded within "Accrued expenses" on the Condensed Consolidated Balance Sheets was $ 0.2 million and zero , respectively, related to asbestos litigation. Based upon the most recent information available to the Company regarding such claims, there were a total of 333 cases pending against the Company as of June 30, 2024 with Illinois, New York, Pennsylvania and West Virginia having the largest number of cases, as compared with 313 cases that were pending as of December 31, 2023. During the six months ended June 30, 2024, 94 new cases were filed against the Company, and the Company was dismissed from 50 cases and settled 24 cases. Most of the pending cases have not advanced beyond the early stages of discovery, although a number of cases are on schedules leading to or scheduled for trial. The Company believes that its insurance coverage is adequate for the cases currently pending against the Company and for the foreseeable future, assuming a continuation of the current volume, nature of cases and settlement amounts. However, the Company has no control over the number and nature of cases that are filed against it, nor as to the financial health of its insurers or their position as to coverage. The Company also presently believes that none of the pending cases will have a material adverse impact upon the Company’s results of operations, liquidity or financial condition. Other The Company is also a party to routine contract and employment-related litigation matters, warranty claims and routine audits of state and local tax returns arising in the ordinary course of its business. 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 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. The Company expenses legal costs as they are incurred. The Company is not aware of any pending claims or assessments, other than as described above, which may have a material adverse impact on its liquidity, financial position, results of operations, or cash flows.

Malvar Engineering Limited On January 10, 2023, the Company acquired 100 % of the equity interests of Malvar Engineering Limited, including its subsidiaries Arkanum Management Limited and Wakefield Acoustics Limited (collectively, "Wakefield"), for $ 4.1 million in cash, which was financed with a draw on the Company’s revolving credit facility, and $ 0.4 million of deferred cash consideration . As additional consideration, the former owners are entitled to earn-out payments based upon specified financial results through July 31, 2023. Based on projections at the acquisition date, the Company estimated the fair value of the earn-out to be $ 0.6 million. A payment of $ 0.6 million, representing the fully earned amount, was made in the fourth quarter of 2023. Wakefield is a producer of industrial engineered noise control solutions, including custom acoustical gen-set packages, ambient air baffles, acoustical louvres, and skid enclosures, primarily serving server farms for data centers, standby and emergency power generation, oil and gas, petrochemical, commercial construction, infrastructure, and general manufacturing industries. This acquisition advances the Company's position within the industrial silencing and noise attenuation market by adding a range of solutions and access to new geographic markets within the Engineered Systems segment.

These assets were determined to have useful lives of 10 years . The Company has finalized the valuation of assets acquired and liabilities assumed related to the acquisition of Wakefield and Transcend. The purchase accounting related to the Kemco acquisition is 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 this acquisition is not deductible for tax purposes.
