Bradley L. Radoff, Michael Torok and the other participants named herein (collectively, the "Radoff-JEC Group") have filed a definitive proxy statement and accompanying **WHITE** universal proxy card with the Securities and Exchange Commission to be used to solicit votes for the election of its slate of highly qualified director nominees at the 2026 annual meeting of stockholders of Seer, Inc., a Delaware corporation (the "Company").

On June 15, 2026, the Radoff-JEC Group issued the following press release:

**The Radoff-JEC Group Highlights Seer Inc.'s and Chairman and CEO Omid Farokhzad, M.D.'s History of Value Destruction**

![](image_002.jpg)

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:

*"When Seer filed its proxy statement, the Board issued a 4,000-word letter to stockholders that we believe was a collection of inaccurate and misleading statements. In fact, the letter ended with the claim that Seer has the right Board and the right strategy.*

 

***Seer's share price is down 97% since its IPO in December of 2020.<sup>1</sup> If Seer had the right Board and the right strategy, would the share price be down 97% over the past five and a half years?***

 

*We believe change at Seer is urgently needed. The 97% share price decline supports that conclusion. And the fact that Seer Chair and CEO Omid Farokhzad, M.D. has consistently destroyed stockholder value across numerous companies adds to our view that change is urgently needed."*

------

<sup>1</sup> Share price decline from December 4, 2020 through April 10, 2026, the trading day immediately prior to the Radoff-JEC Group's submission of its initial non-binding proposal to acquire the Company.
