CECO ENVIRONMENTAL CORP.

N OT ES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(unaudited)

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, 2025 and the results of operations, cash flows and shareholders’ equity for the three and six months ended June 30, 2025 and 2024. The results of operations for the three and six months ended June 30, 2025 are not necessarily indicative of the results to be expected for the full year. The balance sheet as of December 31, 2024 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, 2024 as filed with the SEC on February 25, 2025 (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.

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 2025

None.

Accounting Standards to be Adopted

In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures, which addresses annual income tax disclosure requirements, primarily around the disclosure of the rate reconciliation and income taxes paid. The ASU is effective for fiscal years beginning after December 15, 2024. The Company is currently evaluating the impact the adoption of the standard will have on the Company’s consolidated financial statements and will adopt the new annual disclosures as required for the fiscal year ended December 31, 2025.

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.

|  | Six months ended June 30, |
(in thousands) |  | 2025 |  |  | 2024 |
Intangible assets – finite life, net at beginning of period |  | $ | 74,050 |  |  | $ | 50,461 |

Amortization expense of finite life intangible assets was $2.9 million and $2.2 million for the three months ended June 30, 2025 and 2024, respectively, and $6.0 million and $4.3 million for the six months ended June 30, 2025 and 2024, respectively. Amortization over the next five years for finite life intangibles is expected to be $10.5 million for the remainder of 2025, $16.3 million in 2026, $15.4 million in 2027, $14.5 million in 2028, $12.8 million in 2029, and $40.5 million thereafter. The weighted average amortization periods for finite life intangible assets was 8.5 years as of June 30, 2025, inclusive of weighted average amortization periods for technology, customer lists, and tradenames of 6.3, 8.9, and 7.9 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.

9

Additionally, property, plant and equipment 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 flow 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 triggering events that would require an interim impairment assessment, or record an impairment of goodwill, indefinite life intangible assets, finite life intangible assets or property, plant and equipment during the three or six months ended June 30, 2025.

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.

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.

12. Income Taxes

The Company files income tax returns in various federal, state and local jurisdictions. Tax years from 2018 forward, with the exception of 2020, remain open for examination by Federal authorities. Tax years from 2018 forward remain open for all significant s tate and foreign authorities.

As of June 30, 2025 and December 31, 2024, the liability for uncertain tax positions totaled approximately $1.3 million and $1.1 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 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, 2025 and December 31, 2024, the Company recorded deferred income taxes of approximately $1.0 million and $0.9 million, respectively, on the undistributed earnings of its foreign subsidiaries.

Income tax expense was $4.5 million and $0.4 million for the three months ended June 30, 2025 and 2024, respectively, and $23.1 million and $1.0 million for the six months ended June 30, 2025 and 2024, respectively. The effective income tax rate for the three months ended June 30, 2025 was 30.9% compared with 7.4% for the three months ended June 30, 2024, and the effective income tax rate for the six months ended June 30, 2025 was 33.2% compared with 13.1% for the six months ended June 30, 2024. The effective income tax rates for the three and six months ended June 30, 2025 and 2024 differ from the United States federal statutory rate. The Company's effective rate is affected by 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. However, based on the current revenue threshold, the Company is currently not subject to Pillar Two taxes.

On July 4, 2025, the legislation HR-1, known as the One Big Beautiful Bill Act (the “Act”), was signed into law. The Act makes several changes to United States tax law, including the limitation on deductibility of interest expense, the capitalization of research expenditures, the allowance of immediate expensing of capital expenditures, and the taxation of foreign earnings. The legislation has multiple effective dates, with certain provisions effective in 2025 and others implemented through 2027. The Company is currently assessing the Act's impact on the consolidated financial statements.

13. Financial Instruments

The Company's financial instruments consist primarily of investments in cash and cash equivalents, receivables and certain other assets, notes payable, foreign debt and accounts payable, which approximate fair value at June 30, 2025 and December 31, 2024, 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 $240.4 million and $221.5 million at June 30, 2025 and December 31, 2024, 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, 2025 and December 31, 2024, the Company had cash and cash equivalents of $36.8 million and $37.8 million, respectively, of which $26.2 million and $29.7 million, respectively, was held outside of the United States, principally in the Netherlands, United Kingdom, United Arab Emirates, and China.

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. While the Company divested of its fluid handling business (also known as its Global Pump Solutions business) in the first quarter of 2025, as discussed in Note 16, the Company retained historical asbestos liabilities and the related legacy insurance policies. In management’s opinion, the complaints typically have been vague, general and speculative, alleging that Met-Pro, along with the numerous other defendants, sold asbestos-containing products and engaged in other related actions which caused injuries (including mesothelioma and death) and loss to the plaintiffs. 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 identify or 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. As of June 30, 2025 and December 31, 2024, the related amounts were $1.5 million and $0.2 million, respectively, which are recorded within "Accrued expenses" and "Other liabilities" on the Condensed Consolidated Balance Sheets.

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. As of June 30, 2025 and December 31, 2024, the related amounts were $0.8 million and $0.1 million, respectively, which are recorded within "Accrued expenses" on the Condensed Consolidated Balance Sheets. Additionally, the Company has $1.0 million recorded within "Accounts payable" as of June 30, 2025 related to the settlement of a litigation matter. 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.

CECO ENVIRONMENTAL CORP.

MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION

AND RESULTS OF OPERATIONS

ITEM 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations

The Company’s Condensed Consolidated Statements of Income for the three and six months ended June 30, 2025 and 2024 reflect the consolidated operations of the Company and its subsidiaries.

CECO Environmental Corp. (“CECO,” “we,” “us,” or the “Company”) is a leading environmentally focused, diversified industrial company, serving the broad landscape of industrial air, industrial water and energy transition markets globally providing innovative technology and application expertise through a collection of focused operating companies with niche leadership positions and well-established brands in fragmented markets with flexible business models and established supply chains. CECO helps companies grow their business with safe, clean, and more efficient solutions that help protect people, the environment and industrial equipment. CECO solutions improve air and water quality, optimize emissions management, and increase the energy and process efficiency for highly engineered applications in power generation, midstream and downstream hydrocarbon processing and transport, chemical processing, electric vehicle production, polysilicon fabrication, semiconductor and electronics production, battery production and recycling, specialty metals, aluminum and steel production, beverage can manufacturing, and industrial and produced water and wastewater treatment, and a wide range of other industrial end markets.

Market Pressures

The senior management team monitors and manages the Company’s ability to operate effectively as the result of market pressures. Against the current backdrop of a rapidly evolving global commercial environment, we believe we are comparatively well-positioned as we execute and manufacture a majority of our business in the same regions in which we sell, with our cost and revenue bases largely aligned as a result. Recently, international trade has been impacted by geopolitical tariff considerations. To mitigate potential tariff-related impacts, we have worked strategically with customers and suppliers to optimize terms and pricing, sourcing locations, and logistics routes and schedules. While we will continue to take a proactive approach on our efforts to mitigate the impacts of tariffs, our business and results could be adversely affected by further policy developments. Additionally, we are currently experiencing shortages of raw materials and inflationary pressures for certain materials and labor. We have secured raw materials from existing and alternate suppliers and have taken other mitigating actions to mitigate supply disruptions; however, we cannot guarantee that we will be able to continue to do so in the future. If we are unable to continue to mitigate the effects of these supply disruptions and/or inflationary pressures, our business, results and financial condition could be adversely affected.

Note Regarding Use of Non-GAAP Financial Measures

The Company’s unaudited condensed consolidated financial statements are prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”). These GAAP financial statements include certain charges the Company believes are not indicative of its core ongoing operational performance.

As a result, the Company provides financial information in this Management’s Discussion and Analysis that was not prepared in accordance with GAAP and should not be considered as an alternative to the information prepared in accordance with GAAP. The Company provides this non-GAAP financial information because the Company’s management utilizes it to evaluate its ongoing financial performance and the Company believes it provides greater transparency to investors as supplemental information to its GAAP results.

The Company has provided the non-GAAP financial measures of non-GAAP operating income and non-GAAP operating margin as a result of items that the Company believes are not indicative of its ongoing operations. These include transactions associated with the Company’s acquisitions, divestiture, and the items described below in “Consolidated Results.” The Company 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. The Company utilizes this information to evaluate its ongoing financial performance. The Company has incurred substantial expense and income associated with acquisitions. While the Company cannot predict the exact timing or amounts of such charges, it does expect to treat the financial impact of these transactions as special items in its future presentation of non-GAAP results.

Recent Accounting Pronouncements

For information regarding recent accounting pronouncements, see Note 2 to the unaudited condensed consolidated financial statements within Item 1 of this Quarterly Report on Form 10-Q.

Liquidity and Capital Resources

When we undertake large jobs, our working capital objective is to make these projects self-funding. We work to achieve this by obtaining customer down payments, progress billing contracts, when possible, utilizing extended payment terms from material suppliers, and paying sub-contractors after payment from our customers, which is an industry practice. Our investment in net working capital is funded by cash flow from operations and by our revolving line of credit under our Credit Facility (as defined below).

At June 30, 2025, the Company had working capital of $98.0 million, compared with $86.3 million at December 31, 2024. The ratio of current assets to current liabilities was 1.34 to 1.00 on June 30, 2025, as compared with a ratio of 1.35 to 1.00 on December 31, 2024.

At June 30, 2025 and December 31, 2024, cash and cash equivalents totaled $36.8 million and $37.8 million, respectively. As of June 30, 2025 and December 31, 2024, $26.2 million and $29.7 million, respectively, of our cash and cash equivalents were held by certain foreign subsidiaries, as well as being denominated in foreign currencies.

For the six months ended June 30, 2025, $19.4 million of cash was used in operating activities compared with $7.9 million provided by operations in the prior year period, representing a decrease of $27.3 million. Cash flow from operating activities in the first six months of 2025 had an unfavorable impact year-over-year primarily due to timing of project-related payments.

Investing Activities

For the six months ended June 30, 2025, net cash provided by investing activities was $3.8 million compared with $6.8 million used in investing activities in the prior year period. For the six months ended June 30, 2025, the Company received $105.8 million related to the sale of the Global Pump Solutions business as discussed in Note 16, offset by $97.6 million used in the acquisition of Profire as discussed in Note 15. In the prior year period, $6.8 million cash used in investing activities was primarily the result of acquisitions of property and equipment.

Financing Activities

For the six months ended June 30, 2025, $14.2 million was provided by financing activities compared with $16.6 million used in financing activities in the prior year period, for an increase of $30.8 million. For the six months ended June 30, 2025, cash provided by financing activities was driven by net borrowings of $19.7 million, primarily to fund the acquisition of Profire as discussed in Note 15, partially offset by $1.0 million of deferred consideration paid for acquisitions, representing the repayment of the remainder of the promissory note associated with the acquisition of Transcend Solutions in 2023. For the six months ended June 30, 2024, the primary uses of cash for financing activities were $6.7 million of net repayments on revolving credit lines and long-term debt, $5.0 million to repurchase common stock, and $2.1 million of deferred consideration paid for acquisitions..

Critical Accounting Estimates

Management believes there have been no changes during the six months ended June 30, 2025 to the items that the Company disclosed as its critical accounting policies and estimates in Management’s Discussion and Analysis of Financial Condition and Results of Operations in the Company’s Annual Report on Form 10-K for the year ended December 31, 2024.

Forward-Looking Statements

This Quarterly Report on Form 10-Q includes forward-looking statements within the meaning of Section 27A of the Securities Act of 1933 and Section 21E of the Securities Exchange Act of 1934, both as amended, which are intended to be covered by the safe harbor for “forward-looking statements” provided by the Private Securities Litigation Reform Act of 1995. Any statements contained in this Quarterly Report on Form 10-Q, other than statements of historical fact, including statements about management’s beliefs and expectations, are forward-looking statements and should be evaluated as such. 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,

29

that could cause actual results to differ materially are discussed under “Item 1A. Risk Factors” of this Quarterly Report on Form 10-Q and in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2024, and include, but are not limited to:

•
the effect of recent acquisitions and the divestiture of our Fluid Handling Business (together, the “transactions”) on business relationships, operating results, and business generally, disruption of current plans and operations and potential difficulties in employee retention as a result of the transactions, diversion of management’s attention from ongoing business operations in connection with the integration of recent acquisitions, the outcome of any legal proceedings that have been or may in the future be instituted related to the Profire transaction or other transactions, the amount of the costs, fees, expenses and other charges related to the transactions, the achievement of the anticipated benefits of transactions, our ability to successfully integrate acquired businesses and realize the synergies from acquisitions, as well as a number of factors related to our business, including the sensitivity of our business to economic and financial market conditions generally and economic conditions in CECO’s service areas;
•
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 relating to supply chain challenges or other customer considerations;
•
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;
•
our ability to repurchase shares of our common stock and the amounts and timing of repurchases;
•
our ability to successfully realize the expected benefits of our restructuring program;
•
economic and political conditions generally;
•
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; and
•
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.

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 (the “SEC”), we undertake no obligation to update or review any forward-looking statements, whether as a result of new information, future events or otherwise.

ITEM 3. QUANTITATIVE AND QUALITAT IVE DISCLOSURES ABOUT MARKET RISK

We are exposed to certain market risks, primarily changes in interest rates. Market risk is the potential loss arising from adverse changes in market rates and prices, such as foreign currency exchange and interest rates. For the Company, these exposures are

30

primarily related to changes in interest rates. We do not currently hold any derivatives or other financial instruments purely for trading or speculative purposes.

The carrying value of the Company’s total long-term debt and current maturities of long-term debt at June 30, 2025 was $240.4 million. Market risk was estimated as the potential decrease (increase) in future earnings and cash flows resulting from a hypothetical 10% increase (decrease) in the Company’s estimated weighted average borrowing rate at June 30, 2025. Most of the interest on the Company’s debt is indexed to SOFR market rates. The estimated annual impact of a hypothetical 10% change in the estimated weighted average borrowing rate at June 30, 2025 is $1.7 million.

The Company has wholly-owned subsidiaries in several countries, including in the Netherlands, Canada, the People’s Republic of China, Mexico, United Kingdom, Singapore, India, United Arab Emirates, Germany, South Korea and Saudi Arabia. In the past, we have not hedged our foreign currency exposure, and fluctuations in exchange rates have not materially affected our operating results. Future changes in exchange rates may positively or negatively impact our revenues, operating expenses and earnings. Transaction (gains) losses included in “Other (income) expense, net” line of the Condensed Consolidated Statements of Income were $(1.4) million and $0.5 million for the three months ended June 30, 2025 and 2024, respectively, and $(0.9) million and $1.6 million for the six months ended June 30, 2025 and 2024, respectively.

ITEM 4. CONTROL S AND PROCEDURES

Evaluation of Disclosure Controls and Procedures

The Company maintains disclosure controls and procedures (as defined in Rule 13a-15(e) of the Securities Exchange Act of 1934 (the “Exchange Act”)) that are designed to ensure that information required to be disclosed by the Company in reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms, and that such information is accumulated and communicated to the Company’s management, including its principal executive officer and principal financial officer, as appropriate, to allow timely decisions regarding required disclosure. The Company’s management, with the participation of the Company’s Chief Executive Officer and Chief Financial Officer, evaluated the effectiveness of the Company’s disclosure controls and procedures as of the end of the period covered by this Quarterly Report on Form 10-Q. Based on that evaluation, our management, including our Chief Executive Officer and Chief Financial Officer, concluded that our disclosure controls and procedures were effective as of June 30, 2025.

Management believes that the condensed consolidated financial statements included in this report present fairly, in all material respects, the Company’s financial condition, results of operations and cash flows for each of the periods presented in this report in conformity with accounting principles generally accepted in the United States of America.

Changes in Internal Control Over Financial Reporting

There were no changes in the Company’s internal control over financial reporting (as defined in Rule 13a-15(f) of the Exchange Act) during the quarter ended June 30, 2025 that materially affected, or are reasonably likely to materially affect, the Company’s internal control over financial reporting.

Limitations on the Effectiveness of Controls

Control systems, no matter how well conceived and operated, are designed to provide a reasonable, but not an absolute, level of assurance that the objectives of the control system are met. Further, the design of a control system must reflect the fact that there are resource constraints, and the benefits of controls must be considered relative to their costs. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, within the Company have been detected. Because of the inherent limitations in a cost-effective control system, misstatements due to error or fraud may occur and not be detected. The Company conducts periodic evaluations of its internal controls to enhance, where necessary, its procedures and controls.
