SEI Investments Co. (SEIC) Form 4: Director Thomas C. Naratil reported the acquisition of 2,076 shares of SEIC common stock on 22 Jul 2025. The shares were granted as employment compensation and are structured as Restricted Stock Units (RSUs) that will vest over time. After this initial grant, Naratil now beneficially owns 2,076 shares, all held directly. No derivatives were involved and no cash price was disclosed.
The transaction is immaterial to SEIC’s share count but provides early equity alignment for a recently appointed board member.
