AGENUS INC
AGENBusiness Summary
Agenus Inc. is a clinical-stage biotechnology company focused on discovering and developing immunotherapies for cancer and infectious disease, with its primary business in immuno-oncology where it advances antibody-based programs to activate innate and adaptive immunity, overcome tumor immune evasion, and expand the population of patients who may benefit from immunotherapy. The company also maintains an equity investment in MiNK Therapeutics, Inc., with an approximate fair value of $24.3 million 1 as of December 31, 2025, and a majority ownership of a vaccine adjuvant business through its subsidiary SaponiQx, Inc.
The immuno-oncology drug landscape is highly competitive, with numerous companies developing assets against a wide range of targets, and competitors range from small-cap to large-cap companies including programs in both pre-clinical and clinical stages of development. Named competitors include Bristol Myers Squibb, Merck & Co., Regeneron Pharmaceuticals, Roche/Genentech, AstraZeneca, Merck KGaA, GSK, Coherus BioSciences, Incyte, BeiGene, and Checkpoint Therapeutics, among others. For the specific indication of refractory colorectal cancer, competitors include AbbVie, Adagene, Exelixis, Jiangsu Alphamab Biopharmaceuticals, Merck & Co., Replimune, and Xilio Therapeutics.
Agenus generates revenue through a mix of research and development revenue from collaborations, pre-commercial product revenue from early access programs, service revenue, and non-cash royalty revenue related to the sale of future royalties. The company uses internal discovery, translational, clinical and regulatory capabilities together with selected collaborations to advance product candidates, and its primary customer segments are collaboration partners such as Bristol Myers Squibb, Incyte, Merck & Co., and GSK, as well as patients accessing therapies through regulatory-authorized early access pathways.
The company's lead clinical program is botensilimab (BOT or AGEN1181), a multifunctional anti-CTLA-4 antibody designed to activate both innate and adaptive anti-tumor immune responses, alone and in combination with balstilimab (BAL), a fully human monoclonal immunoglobulin G4 anti-PD-1 antibody. BOT and BAL are investigational therapies and have not been approved by the FDA or the European Medicines Agency for commercial sale, however they are accessible through government reimbursement programs in France as well as through out of pocket pay in select European and South American countries. BOT, alone and in combination with BAL, has been evaluated in approximately 1,200 2 patients across more than 60 3 centers worldwide and across nine tumor types, including colorectal cancer, sarcoma, non-small cell lung cancer, hepatocellular cancer, pancreatic cancer, melanoma, ovarian cancer and triple negative breast cancer. In April 2023, BOT in combination with BAL received Fast Track designation from the FDA for the treatment of patients with non-microsatellite instability-high and/or deficient mismatch repair metastatic colorectal cancer without active liver involvement. The company also maintains select clinical-stage immuno-oncology assets including AGEN2373 (CD137 agonist antibody), AGEN1423 (CD73/TGFβ TRAP), AGEN1571 (ILT2), and AGEN1777 (TIGIT bispecific), which were temporarily postponed as part of the December 2024 strategic realignment.
In June 2025, the company announced a strategic collaboration with Zydus Lifesciences Ltd., including the sale of its Emeryville and Berkeley biologics manufacturing facilities, with a total consideration of $91.0 million 4, which closed in January 2026. In May 2024, the company entered into a Purchase and Sale Agreement with Ligand Pharmaceuticals Incorporated covering specified economic interests in selected partnered programs and in BOT and BAL, under which Ligand acquired 31.875% 5 of the development, regulatory and commercial milestones then payable to the company under agreements with BMS, UroGen, Gilead, Merck and Incyte, 18.75% 6 of the royalties under those agreements, and a 2.625% 7 synthetic royalty on worldwide net sales of BOT and BAL. In July 2024, BMS notified the company that it was voluntarily terminating the license agreement for AGEN1777 effective January 26, 2025, and rights were returned to the company. In February 2025, the company received formal notice from Incyte terminating the collaboration effective February 2026, and all rights to LAG-3 and TIM-3 were returned to the company. In July 2025, the company's ownership percentage of MiNK dropped below 50%, resulting in a loss of control and deconsolidation in the quarter ended September 30, 2025, and as of December 31, 2025, the company owned approximately 46% 8 of MiNK. In January 2026, France expanded the AAC protocol for botensilimab plus balstilimab to include certain ovarian cancers and soft-tissue sarcomas. In January 2026, the company closed its strategic collaboration with Zydus Lifesciences Ltd., including the sale of its Emeryville and Berkeley biologics manufacturing facilities, with a total consideration of $91.0 million 9.
Total revenues for the year ended December 31, 2025 were $114.196 million 10, compared to $103.463 million 11 for the year ended December 31, 2024. Net loss attributable to Agenus Inc. common stockholders was $0.101 million 12 for 2025, compared to $227.427 million 13 for 2024. The company recognized pre-commercial product revenue of approximately $4.2 million 14 during 2025, representing sales of BOT+BAL provided to patients through regulatory-authorized early access pathways. Non-cash royalty revenue related to the GSK agreement increased to approximately $108.6 million 15 for 2025 from $101.0 million 16 for 2024. Research and development expense decreased 49% to $79.3 million 17 for 2025 from $155.5 million 18 for 2024. The company recognized a gain from deconsolidation of MiNK Therapeutics, Inc. of $100.9 million 19 for 2025.
Business Outlook
The company intends in 2026 to seek Accelerated Approval in the United States and Conditional Approval in the European Union for BOT plus BAL in refractory microsatellite-stable metastatic colorectal cancer without active liver metastases. The company, together with the Canadian Cancer Trials Group, is conducting BATTMAN/CO.33, a global Phase 3 trial of botensilimab plus balstilimab versus best supportive care in refractory MSS/mismatch repair proficient colorectal cancer, which is expected to enroll approximately 830 20 patients across more than 100 21 sites in Canada, France, Australia and New Zealand and is intended to support potential regulatory filings in the United States and Europe.
The company is evaluating potential future registration-enabling trial designs in neoadjuvant, first-line and later-line colorectal cancer, informed by data from studies including the NEST study which showed a pathological complete response rate improved to 47% 22 in MSS tumors when the median time to surgery was extended, and the UNICORN Phase 2 study which showed patients with dMMR/MSI-H tumors achieved a 93% 23 pCR and 100% 24 pMR, while patients with pMMR/MSS colorectal cancer had a 29% 25 pCR and 36% 26 pMR rate. Whether and when any additional registration-enabling trials will be initiated will depend on capital availability and strategic transactions, including partnerships, licensing arrangements and joint ventures.
Research and development expense decreased 49% to $79.3 million 27 for the year ended December 31, 2025 from $155.5 million 28 for the year ended December 31, 2024, primarily due to a $51.9 million 29 decrease in third-party services and other expenses, a $14.3 million 30 decrease in personnel related expenses, a $2.0 million 31 decrease in other research and development expenses, and a $7.9 million 32 decrease in expenses attributable to the activities of subsidiaries. General and administrative expense decreased 24% to $54.4 million 33 for 2025 from $71.9 million 34 for 2024, primarily due to a $9.1 million 35 decrease in personnel related expenses, a $3.4 million 36 decrease other general and administrative expenses and a $5.1 million 37 decrease in expenses attributable to the activities of subsidiaries.
In January 2026, the company divested its assets that comprised its in-house planned manufacturing division, including the sale of its owned facility in Berkeley, California as well as its leasehold interest in its facility in Emeryville, California, and entered into a contract manufacturing agreement with Zydus for certain of its manufacturing needs. As of February 28, 2026, the company had 81 38 employees, of whom 19 39 held Ph.D. degrees and 5 40 held M.D. degrees.
The company's research and development expenses for the years ended December 31, 2025, 2024, and 2023, were $79.3 million 41, $155.5 million 42, and $234.6 million 43, respectively. The company maintains an effective registration statement covering up to $300.0 million 44 of common stock, preferred stock, warrants, debt securities and units, which includes prospectuses covering the offer, issuance and sale of up to 20.6 million 45 shares of common stock from time to time in at-the-market offerings pursuant to an At Market Issuance Sales Agreement with B. Riley Securities, Inc. The company sold approximately 9.7 million 46 and 0.2 million 47 shares of its common stock pursuant to the Sales Agreement during the year ended December 31, 2025 and the period of January 1, 2026 through March 12, 2026, respectively, and received aggregate net proceeds totaling $36.9 million 48. As of March 12, 2026, approximately 8.2 million 49 shares remained available for sale under the Sales Agreement.
The company has historically incurred net losses and anticipates that it will continue to incur net losses in the future, with net losses for the years ended December 31, 2025, 2024, and 2023, of $3.1 million 50, $232.3 million 51 and $257.4 million 52, respectively. As of December 31, 2025, the company had $3.0 million 53 of cash and cash equivalents. Based on its current plans and projections, the company believes that its cash resources as of December 31, 2025, plus funding received in the first quarter of 2026 and anticipated funding will be sufficient to satisfy its critical liquidity requirements into 2027. However, the company will in any event require additional capital in order to complete clinical development of its current programs.
The company's ability to use net operating losses and research and development credits to offset future taxable income may be subject to certain limitations. As of December 31, 2025, the company had U.S. federal and state net operating loss carryforwards of $992.4 million 54 and $532.5 million 55, respectively, which may be available to offset future taxable income. The federal NOLs include $445.9 million 56 which expire at various dates through 2044 and $546.5 million 57 which carryforward indefinitely. As of December 31, 2025, the company also had U.S. federal and state research and development tax credit carryforwards of $3.8 million 58 and $1.2 million 59, respectively, which may be available to offset future tax liabilities and begin to expire in 2026.
Risk Factors
The company's business is highly dependent on the success of botensilimab and related combination therapy programs, which still require significant additional clinical development, and there is no guarantee that these product candidates will be approved or successfully commercialized. The company has incurred net losses in every year since its inception, with net losses for the years ended December 31, 2025, 2024, and 2023 of $3.1 million 60, $232.3 million 61 and $257.4 million 62, respectively, and as of December 31, 2025 had an accumulated deficit of $2.18 billion 63. As of December 31, 2025, the company had only $3.0 million 64 of cash and cash equivalents, and its independent registered public accounting firm has included an explanatory paragraph relating to its ability to continue as a going concern in its report on the audited financial statements. The company faces intense competition from major pharmaceutical companies and specialized biotechnology companies with substantially greater financial, technical and other resources, and many competitors have products on the market or in development for the treatment of cancer. The company's ability to use its net operating loss carryforwards of $992.4 million 65 (federal) and $532.5 million 66 (state) may be subject to limitations under Sections 382 and 383 of the Code due to ownership changes, and the company may not be able to utilize a material portion of these NOLs.
Management Priorities
Management's message emphasizes a strategic focus on capital execution for programs with the clearest path to meaningful clinical and commercial value, led by BOT/BAL in colorectal cancer and selected other tumor types, following a strategic realignment announced in December 2024 that prioritized the botensilimab/balstilimab program and temporarily paused certain non-core preclinical and clinical activities while evaluating partnering and targeted funding opportunities. The company intends in 2026 to seek Accelerated Approval in the United States and Conditional Approval in the European Union for BOT plus BAL in refractory microsatellite-stable metastatic colorectal cancer without active liver metastases. Key strategic priorities include advancing late-stage development of BOT/BAL, supporting responsible paid patient access programs as well as clinical trials, and maintaining manufacturing flexibility through strategic collaborations with an emphasis on the Zydus collaboration.
