Summary

On December 29, 2020, Acer Therapeutics, Inc. (“Acer” or the “Company”), in its capacity as a nominal defendant, entered into a Stipulation of Settlement (the “Stipulation”) in the above-captioned shareholder derivative action filed derivatively on behalf of Acer, in the United States District Court for the District of Massachusetts (the “Court”) against certain current and former directors and officers of the Company and against the Company as a nominal defendant (the “Massachusetts Action”)². The Stipulation and the settlement contemplated therein (the “Settlement”), subject to the approval of the Court, is intended by the Settling Parties to fully, finally, and forever compromise, resolve, discharge, and settle the Released Claims and to result in the complete dismissal of the Actions with prejudice, upon the terms and subject to the conditions set forth in the Stipulation. The proposed Settlement requires the Company to adopt certain additional corporate governance measures and procedures, as outlined in Exhibit A to the Stipulation, and provides that the filing, prosecution, and resolution of the Actions were a consideration in the Company’s implementation of the corporate governance reforms. In exchange, Defendants agree to pay, or cause to be paid, subject to Court approval, a Fee and Expense Award to Plaintiffs’ Counsel of five hundred thousand dollars ($500,000.00). Incentive Awards will be paid out of the Fee and Expense Award in the amount of five thousand dollars ($5,000.00) the plaintiff in the Massachusetts Action and in the amount of two thousand dollars ($2,000.00) to each of the plaintiffs in the Delaware and New York Actions, subject to Court approval.

¹ All capitalized terms used in this notice, unless otherwise defined herein, are defined as set forth in the Stipulation.
² Although filed only in the Massachusetts Action, the Stipulation and Settlement also resolves the consolidated derivative action in the United States District Court for the District of Delaware captioned In re Acer Therapeutics, Inc. Derivative Litigation, Lead Case No. 1:19-cv-01505-MN (the “Delaware Action”) as well as the derivative action in the United States District Court for the Southern District of New York captioned King v. Schelling, et al., Case No. 1:20-cv-04779- GHW (the “New York Action” and together with the Massachusetts Action and the Delaware Action, the “Actions”).
