Aldeyra Therapeutics Inc

Item 1. Legal Proceedings.

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 alleges 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 alleges 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 seeks, 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 4, 2024, defendants filed a motion to dismiss the amended complaint, the plaintiff filed opposition to the motion on April 18, 2024, and defendants filed a reply to plaintiff’s opposition on May 20, 2024. Oral argument on the motion to dismiss was heard on July 24, 2024. We dispute the plaintiff's claims and intend to vigorously defend the suit. At this time, we cannot reasonably predict the outcome or estimate potential losses, if any, that could result from this matter.

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.
