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.
