Bell Michael Brian 4

What Happened
Michael Brian Bell, Chief Financial Officer of Guardant Health, had 2,039 restricted stock units (RSUs) convert into 2,039 shares on June 15, 2026.

Context
This was a scheduled RSU vesting and company share‑withholding to cover taxes (common practice, akin to a cashless exercise for RSUs). It is not an open‑market purchase or sale that directly signals buying or selling intent by the insider. The Form 4 shows conversion of derivative RSU units into common shares and the withholding disposition to satisfy tax obligations.
