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 September 30, 2022 and the results of operations, cash flows and shareholders’ equity for the three months and nine months ended September 30, 2022 and 2021. The results of operations for the three months and nine months ended September 30, 2022 are not necessarily indicative of the results to be expected for the full year. The balance sheet as of December 31, 2021 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, 2021 as filed with the SEC on March 14, 2022 (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.

COVID-19 A novel strain of coronavirus (“COVID-19”) surfaced in late 2019 and has spread around the world, including to the United States. In March 2020, the World Health Organization characterized COVID-19 as a pandemic. As of September 30, 2022, the virus, including new emerging variants, continues to spread and has had a significant impact on worldwide economic activity, macroeconomic conditions, and the end markets of the Company's business. The outbreak and a continued spread of COVID-19 has resulted in a substantial curtailment of business activities worldwide and has caused weakened economic conditions, both in the United States and abroad. Although vaccines are available in various countries where the Company operates, it is possible the COVID-19 pandemic may continue to have a negative impact on the Company's ongoing operations and the end markets in which it serves. However, the full impact of the COVID-19 pandemic continues to evolve as of the date of this filing, and as such, it is uncertain as to the full magnitude or lasting impact that the pandemic will have on the Company’s financial condition, liquidity, and future results of operations. Management is actively monitoring the impact of the pandemic on its financial condition, liquidity, operations, suppliers, industry, and workforce.
