Freidin Aaron 4

What Happened

• Aaron Freidin, Chief Financial Officer of GRAIL, sold a total of 3,147 shares in open-market transactions: 655 shares on 2026-03-05 at $53.01 ($34,722), 2,407 shares on 2026-03-09 at $47.93 ($115,368), and 85 shares on 2026-03-09 at $46.74 ($3,973). Combined proceeds were roughly $154,063.
• These were disposals (sales), not purchases. According to the filing footnote, the trades represent automatic "sell-to-cover" transactions executed by the broker to cover withholding taxes related to award vesting/share delivery — i.e., routine tax-related sales rather than an open-market decision to reduce ownership.

Context

• Sell-to-cover (tax withholding) sales are common when restricted stock or other awards vest and generally reflect tax obligations rather than a directional bet on the stock. Such sales are less informative about management’s view of the company than open-market purchases.
• These transactions are coded as sales (S). There were no purchases, option exercises, or gifts reported in this filing.
