Immunome Overview Harnessing the power of the most - educated components of the human immune system • Immunome leverages its proprietary Discovery Engine, which enables unbiased interrogation of human memory B cells, to simultaneously identify potential first - in - class antibody therapeutics and novel antigen targets • Focused on oncology and infectious diseases – Two lead discovery programs: oncology (targeting IL - 38) and infectious disease (targeting SARS - CoV - 2) – Anticipate filing INDs for both programs in 2021 • Discovery Engine efficiency potentially allows 1 - 2 programs entering IND - enabling studies per year – Discovery Engine also allows for multiple partnerships; currently partnered with U.S. Department of Defense (COVID - 19) and pH Pharma (oncology antibody - drug conjugates) • Experienced management team and advisory board with deep scientific and operational expertise • Broad intellectual property estate covering all aspects of the Discovery Engine Immunome, Inc. | Page 3

Immunome, Inc. | Page 4 Immunome Approach Our approach harnesses the power of human memory B cells to discover first - in - class therapeutic monoclonal antibody candidates directed at potentially novel targets Partnerships • Contract from U.S. Department of Defense to fund COVID - 19 program, up to $13.3M • Oncology partnership (antibody - drug conjugate) with pH Pharma Infectious Diseases • Rapid identification of antibodies from convalescing patients • COVID - 19 Biosynthetic Convalescent Plasma (BCP) IND filing anticipated in 1H 2021 • Growing portfolio of 50+ novel antibody - target pairs • Lead discovery program IND filing anticipated 2H 2021 Oncology Growth strategy anticipates 1 - 2 programs entering IND enabling studies per year

The Power of Memory B Cells Memory B cells are critical players in human immune response • Memory B cells are a subset of B cells that remember specific antigens and allow for a rapid antibody response upon re - challenge 1 • Memory B cells produce the high - affinity antibodies needed to fight disease • In oncology, the presence of memory B cells in tumors is associated with favorable outcomes in response to immunotherapy 2 - 4 • Immunome immortalizes memory B cells into large, stable hybridoma* libraries; we then interrogate thousands of individual hybridoma - produced antibodies to find unique, therapeutically - relevant antibody / antigen target pairs Immunome, Inc. | Page 5 1.

Oncology

Oncology Landscape Today Immunome, Inc. | Page 9 • Despite significant advances, the five - year survival rate for patients with advanced malignancies of the lung, liver, stomach, pancreas and other organs is less than 10% • Discovery of new targets and novel therapeutics for cancer treatment is vitally important • Immunome’s efforts are guided by patients who have effectively mounted a defense against their disease • The Immunome Discovery Engine simultaneously identifies antibodies and their antigen targets by interrogating the patient’s memory B cells in an unbiased manner

Challenges with Oncology Therapies • T cell targeted immuno - oncology approaches have redefined the way we treat cancer • Large number of patients, however, cannot be treated using T cell - targeted approaches • Tumors subvert immunity by multiple mechanisms, often simultaneously 1 • T cell compartment does not act in isolation, needing to engage other arms of the immune system Immunome, Inc. | Page 10 Limited understanding of the diversity and complexity of human tumors 1.

Bloch et al J Clin Invest https://doi.org/10.1172/JCI138745 CHALLENGES WITH CONVALESCENT PLASMA • Donor - to - donor variation; single donor will differ over the course of convalescence • Unscalable supply a single donor only treats 2 - 3 patients, which makes large - scale prophylactic treatment untenable • Must match donor to patient Treating patients with convalescent plasma CONVALESCENT PLASMA OPPORTUNITIES • Convalescing patients mount antibody responses to viral proteins in addition to Spike – Convalescent plasma has the potential to contain antibodies against several different viral proteins (e.g. S, N, Nsp5) • A broad response may induce multiple viral clearance mechanisms • National COVID - 19 Convalescent Plasma Project, among others, focus on convalescent plasma for COVID - 19 patients

IMM - BCP - 01 Program Summary Immunome, Inc. | Page 24 • Leverages the unbiased nature of the Immunome Discovery Engine to both capture the memory B cells of convalescent COVID - 19 patients and identify antibodies against multiple viral proteins – Patients make antibodies to multiple viral proteins, including Spike • The Immunome Discovery Engine has already identified potential antibodies against multiple viral proteins • Over 50% of them appear to bind to antigens other than Spike protein • Targeting multiple viral proteins and eliciting multiple anti - viral mechanisms may potentially decrease the likelihood of resistance to any one antibody or target • If successful, IMM - BCP - 01 could be a treatment for COVID - 19 patients, as well as a prophylactic for individuals at higher risk of contracting the SARS - CoV - 2 virus • Anticipated BCP program (IMM - BCP - 01) IND filing in 1H 2021
