CVD Equipment Corporation

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheet of CVD Equipment Corporation (the “Company”) as of December 31, 2025, the related consolidated statements of operations, changes in stockholders’ equity and cash flows for the year ended December 31, 2025, and the related notes (collectively referred to as the “financial statements”). In our opinion, based on our audit, the financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2025, and the results of its operations and its cash flows for the year ended December 31, 2025, in conformity with accounting principles generally accepted in the United States of America.

We also have audited the adjustments to the 2024 financial statements to retrospectively apply the change in accounting for income taxes as a result of the adoption of Accounting Standards Update No. 2023-09, Income Taxes (Topic 740): Improvement to Income Tax Disclosures , as described in Note 2 and 9. In our opinion, such adjustments are appropriate and have been properly applied. We were not engaged to audit, review, or apply any procedures to the 2024 financial statements of the Company other than with respect to the adjustments and, accordingly, we do not express an opinion or any other form of assurance on the 2024 financial statements taken as a whole.

Basis for Opinion

These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on the Company’s financial statements based on our audit. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (“PCAOB”) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audit we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Company’s internal control over financial reporting. Accordingly, we express no such opinion.

Our audit included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audit also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audit provides a reasonable basis for our opinion.

Critical Audit Matters

The critical audit matters communicated below are matters arising from the current period audit of the financial statements that were communicated or required to be communicated to the audit committee and that: (1) relate to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the financial statements, taken as a whole, and we are not, by communicating the critical audit matters below, providing separate opinions on the critical audit matters or on the accounts or disclosures to which they relate.

Revenue Recognition – Estimated Total Contract Costs

Description of the Matter

As discussed in Notes 2 and 3 to the consolidated financial statements, the Company recognizes revenue from the sale of systems (“System Projects”) over time by using an input method based on costs incurred as it best depicts the Company’s progress toward satisfaction of the performance obligation. Under this method, revenue arising from such contracts is recognized as work is performed based on the ratio of costs incurred to date to the total estimated costs at completion of the performance obligations. The estimation of these costs requires judgment by the Company given the unique product specifications and requirements for contracts related to the design, development, and manufacture of the system. During the year ended December 31, 2025, the Company recognized approximately $20.8 million of revenue recognized over time.

Subjective judgment is required by management in determining the assumptions in estimating the estimated costs to complete on contracts for which revenue is recognized over time using a cost-to-cost model. Complex auditor judgment was required in evaluating initial cost estimates and expected costs to complete.
