On April 13, 2026, the following email was distributed to employees of Seer, Inc.

Hi Seer Team,

I want to reach out and share a brief update on our company. As you may have seen, two of our stockholders, Bradley L. Radoff and Michael Torok, acting together as an entity called the Radoff-JEC Group, issued a press release announcing a highly contingent, non-binding and unsolicited proposal to acquire all outstanding shares of Seer’s Class A common stock.

Consistent with its fiduciary duties and in consultation with our independent financial and legal advisors, the Board of Directors will carefully review the proposal and determine the course of action that’s in the best interest of the Company and our stockholders. The Board will announce its decision in due course.

The Radoff-JEC Group also nominated three director candidates to stand for election to our Board at our 2026 Annual Meeting of Stockholders. The Corporate Governance and Nominating Committee of our Board will consider the Radoff-JEC Group’s nominees in accordance with the Company’s bylaws. The Board will present its formal recommendation regarding the Radoff-JEC Group’s nominations in the Company’s proxy statement.

It is important for you to know we have a team focused on managing this matter, and the best thing that you can do is remain focused on your day-to-day responsibilities. As we’ve made clear before, we believe that there is significant opportunity ahead as we grow our platform and continue to advance our mission. We have a comprehensive platform of products and services that now represent the state-of-the-art in scalable, unbiased proteomics.

In short, it remains business as usual for all of us at Seer – we’re relying on you to continue the important work underway to support the scientific community with tools that help them achieve exceptional outcomes. The Board and management team will continue to do our part and take actions that we believe are in the best interests of the Company and all stakeholders.

As a reminder, it is important that we speak with one voice. If you receive any media inquiries regarding this matter, please forward them to Patrick Schmidt at [email protected]. Investor or other third party inquiries should be sent to [email protected].

Thank you again for your ongoing commitment to Seer.

Sincerely,

Omid

Information relating to the foregoing can also be found in Seer’s definitive proxy statement for its 2025 Annual Meeting of Stockholders (the “2025 Proxy Statement”), which was filed with the SEC on May 28, 2025, and is available here. Particular attention is directed to the sections of the 2025 Proxy Statement captioned “Board of Directors and Corporate Governance,” “Executive Compensation,” “Named Executive Officer Compensation Overview,” “Security Ownership of Certain Beneficial Owners and Management” and “Certain Relationships, Related Party and Other Transactions.” To the extent that holdings of such participants in Seer’s securities have changed since the amounts printed in the 2025 Proxy Statement, such changes have been reflected on the following filings: for Mr. Farokhzad, on May 22, 2025, August 21, 2025, November 21, 2025, December 11, 2025, February 5, 2026, and February 19, 2026; for Ms. Gulyani, on July 9, 2025; for Mr. Langer, on July 9, 2025; for Mr. McGuire, on July 9, 2025 and December 11, 2025; for Mr. Nishar, on June 16, 2025 and July 9, 2025; for Mr. Ro, on September 3, 2025; for Mr. Roelofs, on July 9, 2025; and for Mr. Horn, on May 22, 2025; August 21, 2025; November 21, 2025, February 5, 2026, and February 19, 2026.
