Seer Board of Directors Issues Letter to Shareholders Demonstrating the Strength and Experience of Seer’s Director Nominees

REDWOOD CITY, Calif., July 08, 2026 (GLOBE NEWSWIRE) -- Seer, Inc. (NASDAQ:SEER) ("Seer" or the "Company") today issued a letter to stockholders containing important information for shareholders to consider in connection with the Company’s upcoming Annual Meeting of Stockholders (the "Annual Meeting") to be held on July 28, 2026. Stockholders as of May 29, 2026 will be entitled to vote at the Annual Meeting.

The Board recommends that stockholders vote "FOR" the election of Seer’s seven highly qualified nominees on the BLUE proxy card.

The full text of the letter follows:

Dear Fellow Seer Stockholder,

At our upcoming Annual Meeting of Stockholders on July 28, 2026, your vote is critical to the continued success of Seer.

Seer has a purpose-built Board of Directors with the expertise needed to guide a category-creating life sciences tools company. This Board is committed to overseeing our strategy to pioneer the nascent space of proteomics using the Board’s decades of industry knowledge and insight.

At the Annual Meeting, Bradley Radoff and Michael Torok are attempting to replace three of your Board’s sitting directors - Seer’s Co-Founder, CEO and Chair Omid Farokhzad, M.D., Terrance McGuire and Dipchand (Deep) Nishar - with candidates who bring no proteomics experience, no life sciences tools experience and no platform operating experience. Radoff and Torok have offered no plan to build Seer. Their only desire is to strip Seer of its cash. Additionally, their nominees raise serious concerns regarding independence and their ability to act in the best interests of all stockholders.

The Three Directors that Radoff and Torok Are Trying to Remove Are Critical to Seer’s Future

Omid Farokhzad, M.D. Co-Founder, CEO and Chair; Director since 2017 ✓ Scientific architect of the Proteograph® Product Suite ✓ Founder of multiple life sciences platform companies ✓ Author of 200+ scientific papers and inventor on 250+ patents ✓ Seer’s largest long-term stockholder, together with family entities	Terrance McGuire Founding Partner of Polaris Partners; Director since 2017 ✓ Decades of healthcare investing and company- building experience ✓ Proven capital allocation and governance judgment ✓ Investor in Seer at inception and again at Seer’s IPO ✓ One of Seer’s longest-term stockholders	Dipchand (Deep) Nishar Technology and Growth Leader; Director since 2021 ✓ Former Senior Managing Partner at SoftBank Vision Fund ✓ Former Managing Director at General Catalyst ✓ Former senior executive at LinkedIn and Google ✓ Deep capital markets, growth investing and corporate strategy expertise

Seer’s Nominees Have the Right Experience, Radoff and Torok’s Nominees Do Not

The Board thoughtfully evaluated the three director candidates identified by Radoff and Torok and unanimously determined that they lack the relevant skillsets, experience and independence required to oversee a complex proteomics company at a critical stage of its evolution in a nascent market. The Board also offered, in good faith, to interview these candidates. Radoff and Torok declined to make them available for customary interviews. Radoff and Torok’s actions demonstrate an unwillingness to work constructively with the Board, and we believe that their nominees would diminish the overall quality of our purpose-built Board.

The issue is not whether Radoff and Torok’s nominees have experience in other fields. The issue is whether they have the right experience for Seer. They do not.

Radoff and Torok are not merely proposing alternative directors. They are trying to install nominees who, in our view, appear selected to advance their short-term agenda.

Support Long-Term Value Creation, Vote "FOR" Seer Today

Do not let Radoff and Torok derail Seer’s progress by replacing three critical members of the Board as we continue to build a new market in deep, unbiased proteomics.

Protect the value of your investment and vote the BLUE proxy card today "FOR" Seer’s seven highly qualified director nominees:

Omid Farokhzad, M.D.; Meeta Gulyani; Robert Langer, Sc.D.; Terrance McGuire; Dipchand (Deep) Nishar; Isaac Ro; and Nicolas Roelofs, Ph.D.

Thank you for your continued support of Seer.

Sincerely,

The Seer Board of Directors
