3 Broad I-O portfolio: enabling optimal combos 3

4 Agenus Five Year Growth Plan: balancing low & high risk initiatives Advance on most rapid path to BLA Develop, register, and launch anti-pd-1/ctla-4 mab combinations in validated indications Pursue novel breakthrough indications to expedite market entry Leverage novel targets for market expansion Pursue optimal I-O mab and vaccine combinations with anti-ctla-4 +/- anti-pd-1 Progress partnered programs (GITR, OX40, TIM-3, LAG-3) towards registration Advance Ab programs against innovative undisclosed targets to the clinic Engage in strategic partnerships 4

5 Current partnerships QS-21 Stimulon : adjuvant for Shingrix GSK filed for registration in U.S., Canada and Europe Royalties and milestones partly monetized 1 undisclosed target Lead selection completed Up to $100 million in milestones Pre-clinical: LAG-3, TIM-3, TIGIT, 2 undisclosed Royalty rates are generally 6-12%* Clinical: GITR, OX40 Royalty rate 15% Up to $510 million in milestones across all programs * *Incyte eligible for 15% royalty for TIGIT 5

6 Clinical Strategy

7 New clinical development paradigm compressed Risk AGEN1884 / AGEN Vaccine AGEN1884 / AGEN2034 Solid Tumors Efficacy unknown AGEN1884 / AGEN Novel CPM (A, B, C) AGEN1884 / AGEN2034 Solid Tumors Efficacy proven Conventional time to BLA AGEN1884 = anti-ctla-4 mab AGEN2034 = anti-pd-1 mab CPM = checkpoint modulator 10 years 7

8 anti-ctla-4 + anti-pd-1: first clinically validated I-O mab combo anti-ctla-4 (low dose) combined with anti-pd-1/pd-l1 is the only validated mab combination with improved efficacy and safety profile Near doubling of clinical response - from 25% to ~57% in NSCLC (1) Control of CTLA-4 + PD-1/PD-L1 targeted therapies could offer a pricing advantage Provides a foundation for mabs against novel checkpoints that are yet to show efficacy in the absence of CTLA-4 antagonism 1. Hellmann et al. Lancet Oncol 2017 *Anti-CTLA-4 antibody AGEN1884 is partnered with Recepta for certain South American territories 8

9 Targeting PD-1 has clinical benefit but combining with CTLA-4 antagonism works better anti-ctla-4 (low dose) combination with anti-pd-1/pd-l1 reduces development risk and expands markets anti-ctla-4 and anti-pd-1 mab combination is already approved in metastatic melanoma & almost doubles clinical benefit in 1L NSCLC (1) CTLA-4 + PD-1/PD-L1 antagonists +/- mabs targeting novel checkpoints have shown compelling data in preclinical models 1. Hellmann et al. Lancet Oncol 2017 *Anti-CTLA-4 antibody AGEN1884 is partnered with Recepta for certain South American territories 9

10 Metastatic virally induced malignancies*: appealing target for Agenus Clinical development: SOC marginally changed after the approval of Avastin in combination with chemo in 1L No effective treatment options in 2L; unmet medical need Clinical activity of other anti PD-X in virally induced and HPV driven malignancy (HNSCC HPV+) suggests that AGEN1884 administration could lead to an ORR 15% in all comers, > 20% in PD-L1+ Regulatory: US: Possibility of applying for Breakthrough Designation, assuming hypotheses are backed up by clinical data, Accelerated Approval possible EU: Possibility of applying for conditional marketing authorization Commercial: Potential niche opportunity with most of the patients from Japan and South Korea where premium prices for unmet medical needs are commonly given and where there is no off-label use reimbursed * Anticipated in cervical cancer 10
