Seer, Inc. proxy contest: the Radoff-JEC Group, which beneficially owns 4,277,528 shares of Class A common stock (approximately 7.7%), filed a supplement to its proxy statement and is soliciting proxies for Seer’s 2026 Annual Meeting to be held virtually on July 28, 2026. The supplement incorporates disclosures from Seer’s definitive proxy statement, states the Record Date as May 29, 2026 with 55,315,982 shares outstanding on that date, and reiterates voting and pre-registration instructions for stockholders, including procedures for stockholders holding shares in “street name.”
The supplement republishes the company’s security ownership table as of May 11, 2026, shows key holders (e.g., Omid Farokhzad 6,918,732 shares, SoftBank 5,135,383 shares, aMoon Growth Fund 4,923,196 shares) and urges stockholders to sign and return the WHITE universal proxy card.
Seer, Inc. disclosed that its Board of Directors has unanimously rejected a further revised unsolicited, non-binding acquisition proposal from the Radoff-JEC Group. The May 14, 2026 proposal sought to acquire all outstanding Class A common shares for $2.40 per share in cash plus a contingent value right.
The Board, after consulting independent financial and legal advisors, concluded the offer is not in stockholders’ best interests because it significantly undervalues Seer and does not reflect its long-term growth prospects. The Board also noted the proposal implies an equity value meaningfully below the company’s current cash, cash equivalents and investments.
Seer, Inc. President & CFO David R. Horn reported an open-market sale of 7,303 shares of Class A Common Stock at an average price of $1.6913 per share.

The board urges shareholders to use the BLUE proxy card and vote FOR Seer’s slate and all proposals.
