$475 Million in Cash and Cash Equivalents to Support Operating Runway into Second Quarter of 2024

Integrated Discovery Platform Identifies Multiple New Candidates for COVID-19 Prevention and Treatment with Plans to Enter Clinical Trials in the First Quarter of 2023

Waltham, MA – August 15, 2022 – Adagio Therapeutics, Inc. (Nasdaq: ADGI), a clinical-stage biopharmaceutical company focused on the discovery, development and commercialization of antibody-based solutions for infectious diseases, today announced financial results and business highlights for the second quarter ended June 30, 2022.

Adagio continues to leverage its proprietary discovery capabilities to create novel SARS-CoV-2 antibodies intended to overcome current and future viral variants resulting from the ongoing evolution of the SARS-CoV-2 virus. The company has engineered multiple antibodies that not only show activity against all known SARS-CoV-2 variants of concern to date, but which were also identified with the aim to better address future emerging variants. Adagio intends to initiate clinical development of select antibodies in the first quarter of 2023. In parallel, Adagio continues to follow participants enrolled in its STAMP and EVADE Phase 3 clinical trials evaluating adintrevimab for the treatment and prevention of COVID-19. Adagio has inventory of adintrevimab at-the-ready as a potential EUA-ready candidate should adintrevimab-sensitive variants re-emerge.

“We are pleased that our technology has yielded antibodies with the potential to counter future SARS-CoV-2 variants and look forward to advancing multiple candidates as rapidly as possible,” said David Hering, Adagio’s chief executive officer. “Through the achievement of the primary endpoints in our clinical trials with adintrevimab, and our in vitro studies that indicate its broadly neutralizing and potent activity, we have demonstrated our capabilities in the design and development of clinically meaningful antibodies. Importantly, our integrated discovery engine continues to generate unique, broadly neutralizing, and potent mAb candidates for COVID-19 as we enhance our investment in our pipeline of earlier-stage assets. With numerous antibodies identified, we intend to select multiple candidates to advance into the clinic in the first quarter of 2023. We look forward to sharing updates on the company and our long-term strategy, as well as the progress across our programs and research.”

Business Highlights

• In July, Adagio announced that David Hering, who had been serving as the company’s interim chief executive officer and chief operating officer, was named permanent CEO and a director on the company’s Board of Directors.

• Also in July, Adagio announced that following its Annual Meeting of Stockholders, the company formed a new Board of Directors to support its continued commitment to the development of novel antibodies for the prevention and treatment of COVID-19 and other infectious diseases. Industry veterans Tamsin Berry, Marc Elia and Dr. Clive Meanwell were elected to the Adagio Board of Directors. Mr. Elia, founder of M28 Capital Management LP, was appointed chair of the Board of Directors.
