Opinion on the Consolidated Financial Statements

We have audited the accompanying consolidated balance sheet of Kopin Corporation (the “Company”) as of December 28, 2024, the related consolidated statement of operations, comprehensive loss, stockholders’ equity, and cash flows for the year then ended, and the related notes (collectively referred to as the “consolidated financial statements”). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company at December 28, 2024, and the results of its operations and its cash flows for the year then ended**,** in conformity with accounting principles generally accepted in the United States of America.

Going Concern Uncertainty

The accompanying consolidated financial statements have been prepared assuming that the Company will continue as a going concern. As discussed in Note 1 to the consolidated financial statements, the Company has an outstanding litigation matter and has suffered recurring losses and negative cash flows from operations that raise substantial doubt about its ability to continue as a going concern. Management’s plans in regard to these matters are also described in Note 1. The consolidated financial statements do not include any adjustments that might result from the outcome of this uncertainty.

Basis for Opinion

These consolidated financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on the Company’s consolidated 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 consolidated 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 consolidated 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 consolidated 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 consolidated 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 consolidated 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 consolidated financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of these critical audit matters does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating these critical audit matters below, providing separate opinions on these critical audit matters or on the accounts or disclosures to which they relate.

Net product revenue recognized using the cost-to-cost input method

As described in Note 1 to the consolidated financial statements, for certain contracts with prime contractors to the U.S. Government, the Company recognizes revenue over time using the cost-to-cost input method as the Company completes the performance obligations because of the continuous transfer of control to the customer and the lack of an alternative use for the product. Under this method, the Company measures progress towards completion based on the ratio of costs incurred to date to total estimated costs to satisfy the Company’s performance obligation. The cost-to-cost input method requires management to use significant assumptions and judgements to determine the estimated yield to be incurred throughout the customer contract.

We identified a certain assumption used in the estimated yield to determine net product revenue recognized using the cost to-cost input method as a critical audit matter. The principal consideration for our determination is the assumption requires management to use significant judgement in determining the estimated yield throughout the customer contract. Auditing the assumption required significant audit effort and auditor judgment to evaluate the audit evidence obtained.

The primary procedures we performed to address the critical audit matter included:

Research and development revenues recognized using the cost-to-cost input method

As described in Note 1 to the consolidated financial statements, the Company has research and development revenues, whereby control transfers overtime and revenue is recognized based on the extent of progress towards completion of the performance obligation. The Company recognizes revenue for certain of its research and development contracts over time, measuring progress using the cost-to-cost input method as costs are incurred. Under this method, the Company measures progress towards completion based on the ratio of costs incurred to date to total estimated costs to satisfy the Company’s performance obligation. The cost-to-cost input method requires management to use significant assumptions and judgements to estimate costs associated with its contracts with customers. These costs are estimated at contract inception and are monitored and updated throughout the duration of the contract.

We identified the estimated costs used in the cost-to-cost input method to determine the revenue recognized for certain research and development revenue contracts as a critical audit matter. The principal consideration for our determination is that research and development revenue recognized using the cost-to-cost input method requires management to use significant assumptions and judgements in determining the estimated future costs in the cost-to-cost calculation expected to be incurred throughout the customer contract. Auditing these estimates and assumptions required significant audit effort and a high degree of auditor judgment and subjectivity to evaluate the audit evidence obtained.

The primary procedures we performed to address the critical audit matter included:
