AGENUS INC

Item 1. Legal Proceedings

In September 2024, a putative securities class action lawsuit was commenced in the U.S. District Court for the District of Massachusetts naming as defendants Agenus and three current officers. The complaint alleges that the defendants violated Sections 10(b) and 20(a) of the Securities Exchange Act of 1934, as amended, and Rule 10b-5 thereunder, by making false and misleading statements and omissions of material fact related to the efficacy and commercial prospects of botensilimab and balstilimab. The plaintiff seeks to represent all persons who purchased or otherwise acquired Agenus securities between January 23, 2023, and July 17, 2024. The plaintiff seeks damages and interest, and an award of costs, including attorneys’ fees. We have not recorded any accrual for a contingent liability associated with these legal proceedings.

In September 2024, we received a subpoena from the Boston Regional Office of the U.S. Securities and Exchange Commission seeking records relating to certain of our product candidates, correspondence with the FDA, public disclosure, and other matters. We have produced records pursuant to the subpoena.

We are not currently a party to any other material legal proceedings. From time to time, we may be subject to various legal proceedings and claims that arise in the ordinary course of our business activities. Regardless of the outcome, litigation can have a material adverse effect on us because of defense and settlement costs, diversion of management resources and other factors.
