Under the supervision and with the participation of our Disclosure Committee and management, including our Chief Executive Officer and Principal Financial and Accounting Officer, we evaluated the effectiveness of the design and operation of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934 (Exchange Act)) as of the end of the period covered by this report. Based on our management’s evaluation (with the participation of our Chief Executive Officer and our Principal Financial and Accounting Officer), as of the end of the period covered by this report, our Chief Executive Officer and our Principal Financial and Accounting Officer have concluded that our disclosure controls and procedures were effective at the reasonable assurance level.

Changes in Internal Control over Financial Reporting

There has been no change in our internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) of the Exchange Act) during the three months ended March 31, 2025 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

PART II – OTHER INFORMATION

On July 31, 2023, a purported stockholder filed a putative class action lawsuit (the Securities Class Action) in the U.S. District Court for the District of Massachusetts, against us and certain current and former officers, captioned Juliana Paice v. Aldeyra Therapeutics, Inc., et al. (No. 23-cv-11737). On January 2, 2024, the lead plaintiff filed an amended complaint. The lawsuit alleged violations by the defendants of Sections 10(b) and 20(a) of the Securities Exchange Act of 1934 and SEC Rule 10b-5. The plaintiff alleged that the defendants made false or misleading statements or failed to disclose certain information concerning (i) the NDA for and the prospects of ADX‑2191 for the treatment of primary vitreoretinal lymphoma and (ii) the NDA for and the prospects of reproxalap for the treatment of dry eye disease. The lawsuit sought, among other things, compensatory damages on behalf of herself and all persons and entities that purchased or otherwise acquired our securities between January 7, 2021, and October 16, 2023, as well as attorneys’ fees and costs. On March 14, 2025, the court granted defendants’ motion to dismiss the entire case with prejudice.

In addition, from time to time, we are subject to litigation and claims arising in the ordinary course of business but, except as stated above, we are not currently a party to any material legal proceedings and we are not aware of any pending or threatened legal proceedings against us that we believe could have a material adverse effect on our business, operating results, cash flows or financial condition.
