• Issues Open Letter to Atea’s Stockholders Outlining the Case for Boardroom Change Based on Years of Stock Price Underperformance, Poor Decision-Making and Entrenchment Maneuvers
• Believes its Three Highly Qualified Director Candidates Possess the Necessary Ownership Perspectives, Scientific Credibility and Public Company Board Experience to Create Value for Stockholders

HOUSTON / Mar 26, 2025 / Business Wire / Bradley L. Radoff and Michael Torok (together with certain of their affiliates, the “Radoff-JEC Group”), who collectively own approximately 5.4% of the outstanding stock of Atea Pharmaceuticals, Inc. (NASDAQ: AVIR) (“Atea” or the “Company”), today announced that they have nominated three highly qualified director candidates – Howard H. Berman, James Flynn and Mr. Torok – for election to the Company’s Board of Directors (the “Board”) at the 2025 Annual Meeting of Stockholders (the “Annual Meeting”). In connection with its nomination, the Radoff-JEC Group issued the following open letter to stockholders outlining the urgent need for boardroom change:

Fellow Stockholders,

Over the past four months, we have expressed concerns to Atea’s Board about the Company’s stock price performance, strategy, capital allocation and governance practices. Specifically, we have highlighted several key facts:

• Atea’s shares have traded below their net cash value since November 2021.
  
• In May 2023, the Board rejected a bid from Tang Capital Partners, LP (“Tang Capital”) that would have paid Atea stockholders $5.75 per share in cash, plus a contingent value right through which stockholders would be eligible to receive 80% of the net proceeds from the Company’s drug programs.¹ In the 18 months since it rejected Tang Capital’s buyout offer, Atea has burned ~$175 million in cash, or approximately $2.00 per share. Atea’s stock now trades at approximately $3.20, reflecting the current leadership’s inability to create value for stockholders.²
  
  
• During this time, there have been numerous stock sales from insiders at valuations below the price per share offered by Tang Capital, including by Board Chair and CEO Jean-Pierre Sommadossi. Most recently, Lead Independent Director Franklin Berger sold 359,606 shares at or near the Company’s all-time-low share price, immediately before the Company announced it had retained Evercore to advise on an exploration of strategic partnerships and during what would normally be a closed window for insider trading.³
  
  
• After we repeatedly asked the Board to dismiss Mr. Berger and replace him with a qualified, stockholder-oriented Lead Independent Director, the Board appointed Arthur Kirsch in February 2025. As we understand it, the addition of Mr. Kirsch is another example of Mr. Sommadossi continuing to populate the boardroom with long-time and loyal friends. In fact, Mr. Kirsch’s son – who is an Atea stockholder – informed us during a standard investor-to-investor conversation that (a.) he requested a seat on the Atea Board prior to his father Arthur’s appointment and (b.) he and his family are long-time friends of Mr. Sommadossi and his wife.

In addition to highlighting the above fundamental issues, we have also made suggestions to the Board that we believe would ensure proper governance and management of the business while resulting in significant and immediate value for stockholders. The Board has ignored or rejected our ideas.

Accordingly, and with all stockholders’ interests in mind, we have nominated three highly qualified director candidates – Howard H. Berman, James Flynn and Michael Torok – for election to the Board at the Annual Meeting. Our nominees collectively possess corporate governance expertise, an ownership mindset and biotechnology backgrounds. We believe they have the right skillsets and experience to address the issues plaguing Atea today.

With a refreshed Board that is committed to objectively overseeing management and focused on creating stockholder value, we believe Atea can immediately return up to $250 million in cash to stockholders while it continues to evaluate strategic alternatives for its only asset. We look forward to providing stockholders with the opportunity to add fresh perspectives and relevant expertise to the Board at this critical time for the Company. We’ll be in touch over the coming weeks with more details on how to vote for change.

Sincerely,

Bradley L. Radoff and Michael Torok
