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


Critical Experience Needed at Seer		Seer’s Director Nominees	Radoff and Torok’s Nominees

	Proteomics or adjacent scientific platform expertise

	Life sciences tools operating experience

	Experience scaling innovative technology platforms

	Public company governance experience relevant to Seer

	Capital allocation discipline

	Long-term alignment with Seer stockholders

	Direct role in building Seer’s strategy

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.
