Item 4.01. Changes in Registrant’s Certifying Accountant.

Newly Engaged Independent Registered Public Accounting Firm

As previously reported, the Audit Committee of the Board of Directors (“Board”) of Ocugen, Inc. (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. As previously reported, 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.

As a result of this process and in connection with evaluating the proposals from the participating firms, on July 2, 2024, the Board approved the appointment of PricewaterhouseCoopers LLP (“PwC”) as the Company’s independent registered public accounting firm for the fiscal year ending December 31, 2024 as EY will cease providing services following the filing of the Company’s Form 10-Q for the quarter ending June 30, 2024.

During the two most recent fiscal years ended December 31, 2023 and 2022 and the subsequent interim period through July 2, 2024, neither the Company nor anyone on its behalf consulted with PwC with respect to (a) the application of accounting principles to a specified transaction, either completed or proposed, or the type of audit opinion that might be rendered on the Company’s consolidated financial statements, and neither a written report nor oral advice was provided to the Company that PwC concluded was an important factor considered by the Company in reaching a decision as to any accounting, auditing or financial reporting issue, or (b) any matter that was either the subject of a “disagreement” (as defined in Item 304(a)(1)(iv) of Regulation S-K and the related instructions thereto) or a “reportable event” (as described in Item 304(a)(1)(v) of Regulation S-K).

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 July 8, 2024, stating its agreement with the above statements, is attached as Exhibit 16.1 to this report.
