Saia John G. 4

What Happened

• John G. Saia, Chief Legal Officer of Guardant Health (GH), received vested restricted stock units (RSUs) on March 15, 2026. A total of 8,811 shares converted to common stock (7,792 + 1,019). The company withheld 4,622 of those shares to satisfy tax withholding obligations, generating proceeds of $395,135 (4,622 @ $85.49). The RSUs show $0 exercise price because they were restricted stock units converting into shares.

Context

• This was an RSU vesting event with stock withheld for tax purposes (a common, routine transaction), not an open-market sale or purchase. The conversion at $0 reflects RSUs settling into shares; the withholding is effectively a cashless tax payment handled by the company. No 10b5-1 plan or gift was reported.
