Announces Share Repurchase Program

Enters into Agreement with Bradley L. Radoff and Michael Torok

BOSTON – April 17, 2025 – Atea Pharmaceuticals, Inc. (Nasdaq: AVIR) (“Atea” or “Company”), a clinical-stage biopharmaceutical company engaged in the discovery and development of oral antiviral therapeutics for serious viral diseases, today announced the appointment of Howard H. Berman, Ph.D. to its Board of Directors (the “Board”). Dr. Berman will serve as a non-voting observer to the Board through Atea’s 2025 Annual Meeting of Stockholders when he will join the Board as a full voting member.

“We are pleased to welcome Howard Berman to the Atea Board,” said Jean-Pierre Sommadossi, Ph.D., Chief Executive Officer and Founder of Atea. “We look forward to benefitting from Dr. Berman’s industry experience and insights as we advance our global Phase 3 program evaluating the regimen of bemnifosbuvir and ruzasvir for the treatment of hepatitis C virus (HCV) and our efforts to deliver value to Atea’s shareholders.”

“Atea’s de-risked Phase 3 program with its potential best-in-class profile for the treatment of HCV has the potential to disrupt a multi-billion global market,” said Dr. Berman. “I look forward to joining the Board and working with my fellow directors on behalf of all Atea’s shareholders.”

The Company is adding Dr. Berman to the Board as part of its entry into an agreement (the “Agreement”) with Bradley L. Radoff and Michael Torok (together with certain of their affiliates, the “Radoff-JEC Group”). In connection with the Agreement, the Radoff-JEC Group has withdrawn its slate of nominated director candidates and has agreed to vote all of the shares it collectively owns in favor of each of Atea’s Board nominees at the 2025 Annual Meeting.

“We invested in Atea because it has a real opportunity to create significant value for its shareholders,” said Bradley L. Radoff and Michael Torok. “We appreciate the productive engagement we have had with the Company, and we look forward to the contributions Dr. Berman will make to the Board.”

The Company also announced that Franklin Berger has informed the Company of his intention not to stand for reelection at Atea’s 2027 Annual Meeting of Stockholders.

The Agreement with the Radoff-JEC Group, which includes certain customary standstill, voting and other provisions, will be filed by the Company with the U.S. Securities and Exchange Commission as an exhibit to a Current Report on Form 8-K.

Share Repurchase Program and Strategic Alternatives Process

Atea also today announced that its Board has authorized, and will promptly begin executing upon, the repurchase of up to $25 million of the Company’s common stock. This authorization reflects the Company’s commitment to return capital to shareholders, while maintaining the flexibility needed to continue funding its global Phase 3 HCV program and positioning Atea for long-term success.

As previously announced on December 16, 2024, Atea engaged Evercore, a global independent investment bank, to identify potential opportunities to enhance shareholder value. The process includes a review of a broad range of strategic alternatives, including strategic partnerships, acquisition, merger, or other business combination, sale of assets or other strategic transactions. The process is ongoing, and the Company continues to evaluate all options to maximize shareholder value. There is no assurance that the process will result in the completion of any specific transaction or outcome. The Company does not intend to comment further with respect to this review unless or until its Board has approved a definitive course of action, the review process has concluded, or it is determined that other disclosure is appropriate.

Evercore is serving as Atea’s financial advisor and Latham & Watkins LLP is serving as legal counsel. Olshan Frome Wolosky LLP is serving as legal counsel to the Radoff-JEC Group.
