Bell Michael Brian 4

What Happened

• Michael Brian Bell, Chief Financial Officer of Guardant Health, had restricted stock units (RSUs) vest on March 15, 2026, converting to 13,790 shares. To cover tax withholding, 7,413 shares were retained by the company (cashless/net-share settlement) and 3,000 shares were sold in the open market on March 16, 2026. The shares withheld for taxes generated $633,737; the open-market sale netted approximately $261,111 — total proceeds/withholdings of about $894,848.

  • F3, F5, F6: The shares came from multiple RSU awards — a May 9, 2022 RSU award (staggered vesting), a June 7, 2023 performance-based RSU (second tranche achieved and vested 3/15/26), and a June 9, 2023 RSU award (quarterly vesting).

Context

• This was primarily a vesting of RSUs with a net-share settlement to cover taxes (common, routine for executives), followed by a small open-market sale. The mix of withheld shares and sales indicates a cashless/net settlement for tax obligations rather than a standalone buy/sell decision expressing market sentiment. The Form 4 was filed promptly.
