Equity [Abstract] |
Equity | Note N – Equity On March 14, 2024, we filed a Post-Effective Amendment to an Automatic Shelf Registration Statement on Form POSASR (file no. 333-272911) and a Post-Effective Amendments for Registration Statement on Form POS AM (file no. 333-272911) (together, the “Registration Statement”). The Registration Statement included both a base prospectus that covered the potential offering, issuance and sale from time to time of up to $300.0 million of common stock, preferred stock, warrants, debt securities and units of Agenus and a prospectus supplement for the potential offer and sale of up to 6,725,642 shares of common stock (the “Initial ATM Shares”) in “at the market” offerings pursuant to an At Market Issuance Sales Agreement by and between Agenus and B. Riley Securities, Inc. (the “Sales Agent”), dated as of July 22, 2020 (the “Sales Agreement”). On August 8, 2024, we filed an additional prospectus supplement for the potential offer and sale of up to an additional 13,834,015 shares of common stock (together with the Initial ATM Shares, the “Placement Shares”) in “at the market” offerings pursuant to the Sales Agreement. Sales pursuant to the Sales Agreement will be made only upon our instruction to the Sales Agent, and we cannot provide assurances that we will issue any additional Placement Shares pursuant to the Sales Agreement. During the three and nine months ended September 30, 2025, we received net proceeds of approximately $9.0 million and $27.5 million from the sale of approximately 1.7 million and 7.6 million shares, respectively, of our common stock in at-the-market offerings under the Sales Agreement.
