The Radoff-JEC Group Urges Seer, Inc. Stockholders to Vote for Boardroom Change Today

Believes New Independent Directors Are Needed to Correct the Board’s Misaligned Priorities and Prevent Further Value Destruction

Reveals Seer’s Board Has Not Responded to the Radoff-JEC Group’s Stockholder-Friendly Offer Made on June 15 to Resolve the Ongoing Proxy Contest, Demonstrating the Board's Focus on its Own Entrenchment

HOUSTON--(BUSINESS WIRE)--Bradley L. Radoff and Michael Torok (together with certain of their affiliates, the “Radoff-JEC Group” or “we”), who collectively own approximately 7.7% of the outstanding shares of Seer, Inc. (NASDAQ: SEER) (“Seer” or the “Company”), today issued the following statement.

• Seer’s Board of Directors (the “Board”) has destroyed value for stockholders while enriching Company insiders:
  • The Company has posted a -97.0% share price decline since its December 2020 IPO.¹
  • Seer has generated cumulative reported losses exceeding $465 million since its IPO.²
  • Seer has delivered virtually no revenue growth over the last three fiscal years, while investing over $160 million.³
  • The Board has rewarded Chairman and CEO Omid Farokhzad, M.D. with nearly $37 million in cumulative compensation while a stockholder who purchased one share at the time of the IPO ($19.00) would be left with less than $0.63.⁴

• Seer has no plan to create stockholder value under Chairman and CEO Omid Farokhzad, M.D.:
  • Dr. Farokhzad has destroyed more than $1 billion in investor capital across five separate companies, evidence supporting our belief that he is incapable of turning around Seer.⁵
  • The strategic plan overseen by the Board anticipates Seer will not achieve profitability until 2031.⁶
  • The Board rejected our three proposals to acquire Seer for premiums of 33% - 42% to its unaffected share price and a contingent value right – proposals which we believe provide substantially greater certainty of value creation than the Company’s current strategic plan – without even engaging with us.

• Seer’s Board has not responded to our proposal to settle this proxy contest:
  • On June 15, 2026, we proposed to end our ongoing proxy contest in exchange for Seer adopting governance enhancements and conducting a tender offer for 20 million shares at $2.50 per share, which would be in line with the Board’s authorized buyback program and management’s statements that there is a “significant dislocation” in the Company’s share price.⁷
  • More than a week later, the Board has still not responded to our settlement offer – which it requested in the first place – demonstrating that its priority is not delivering value or governance improvements for stockholders.
  • Instead of focusing on opportunities to maximize value for stockholders as Seer’s share price has consistently traded at a significant discount to net cash, the Board has diluted stockholders by repeatedly issuing large grants of restricted stock units and in-the-money options to Dr. Farokhzad and President and CFO David Horn.
