Seer, Inc. reported an Initial Statement of Beneficial Ownership dated 09/02/2025 for reporting person Ro Isaac, filed on 09/03/2025 by power of attorney. The form lists the reporting person as a Director and indicates that no securities are beneficially owned by this individual at the time of the report. The filing is a standalone Form 3 filed by one reporting person and contains no entries in Table I (non-derivative) or Table II (derivative) because the explanation states explicitly that no securities are held. This means the director has not reported direct or indirect ownership of the issuer's stock on this initial SEC Section 16 filing.

Seer, Inc. reporting shows the Radoff Family Foundation directly owns 190,000 Class A shares and a Charitable Account holds 30,000 shares. Bradley L. Radoff is reported as directly owning 1,179,422 shares in Item 4, and when combined with the Foundation and Charitable Account holdings he is associated with 1,399,422 shares, representing approximately 2.6% of Seer’s ~54.8 million outstanding Class A shares. The filing indicates Mr. Radoff has sole voting and dispositive power over the majority of his direct holdings and shared power over the 190,000 Foundation shares.
The document contains an apparent inconsistency: the cover page lists sole voting/dispositive power as 1,209,422 for Mr. Radoff while Item 4 reports 1,179,422 directly owned shares; the filing does not reconcile this difference.
