Item 4.01. Changes in Registrant’s Certifying Accountant.

Subsequent to filing of the Annual Report on Form 10-K for the year ended December 31, 2023 for Ocugen, Inc. (the “Company”) and the Proxy Statement for the Company’s Annual Stockholder Meeting, the Audit Committee (“Audit Committee”) of the Board of Directors of the Company authorized management to initiate a strategic request-for-proposal process soliciting proposals from accounting firms to provide audit services to the Company as its independent registered public accounting firm for the fiscal year ending December 31, 2024. Management requested proposals from several independent registered public accounting firms, including Ernst & Young LLP (“EY”), the Company’s current independent registered public accounting firm, in the process.

On May 31, 2024, EY notified the Company of its decision to decline to participate in the request-for-proposal process and to decline to stand for re-election as the Company’s independent registered public accounting firm for fiscal year 2024, which decision was not the result of any disagreement with the Company. EY will cease providing services following the filing of the Form 10-Q for the quarter ending June 30, 2024.

The reports of EY on the Company’s consolidated financial statements for the fiscal years ended December 31, 2023 and 2022 did not contain an adverse opinion or a disclaimer of opinion, and were not qualified or modified as to uncertainty, audit scope or accounting principles, except that the audit reports of EY on the Company’s consolidated financial statements as of and for the years ended December 31, 2023 and 2022 contained an explanatory paragraph which noted that the Company has suffered recurring losses from operations and there was substantial doubt as to the Company’s ability to continue as a going concern, and the audit report of EY on the Company’s consolidated financial statements as of and for the year ended December 31, 2023 contained an explanatory paragraph related to the restatement of the 2022 consolidated financial statements.

During the years ended December 31, 2023 and 2022, and the subsequent interim period through May 31, 2024, there were (i) no disagreements between the Company and EY on any matter of accounting principles or practices, financial statement disclosure or auditing scope or procedure, which, if not resolved to EY’s satisfaction, would have caused EY to make reference to the subject matter of the disagreement in connection with its report for such years, and (ii) no “reportable events” as defined in Item 304(a)(1)(v) of Regulation S-K for such years and subsequent interim period through May 31, 2024, except for EY’s communication of the material weakness in internal control over financial reporting as of December 31, 2023, as described in Part II, Item 9A (Controls and Procedures) of the Company’s Annual Report on Form 10-K for the year ended December 31, 2023, relating to the design and operating effectiveness of controls over the accounting for collaborative arrangements.

In accordance with Item 304(a)(3) of Regulation S-K, the Company has provided EY with a copy of this Current Report on Form 8-K and requested that EY furnish the Company with a letter addressed to the U.S. Securities and Exchange Commission (“SEC”) stating whether it agrees with the statements made herein and, if not, stating the respects in which it does not agree, as required by SEC rules. A copy of EY’s letter, dated June 6, 2024, stating its agreement with the above statements, is attached as Exhibit 16.1 to this report.
