In July 2021, an Agenus stockholder filed a derivative complaint against members of our board of directors and certain senior management in the Delaware Court of Chancery with Agenus as a nominal defendant. The complaint challenges equity awards made in December 2020 on the ground that they were improperly granted. The complaint asserts claims for breach of fiduciary duty, waste, and unjust enrichment. The plaintiff seeks an award of damages to Agenus, an order rescinding the challenged awards, granting other equitable relief, such as disgorgement, and an award of attorneys’ fees. The defendants have filed a motion to dismiss the complaint in its entirety. The financial impact of the plaintiff's claims is not estimable.
