Saia John G. 4

What Happened
John G. Saia, Chief Legal Officer of Guardant Health (GH), had 1,020 shares issued to him on June 15, 2026 upon the vesting/conversion of restricted stock units (RSUs). The shares were issued at $0 cost to him (RSU vesting). To satisfy tax withholding, the company retained (disposed) 535 of those shares at $129.82 per share, equal to $69,454.

Context
This was RSU vesting and a typical "sell-to-cover" style withholding: the company retained a portion of vested shares to pay the holder's tax liability. Such withholding is routine and does not represent an active decision to sell shares on the open market by the executive. Transaction codes: M = exercise/conversion of derivative (here, RSU conversion), F = payment of tax liability via share withholding.
