Guardant Health CEO Helmy Eltoukhy Exercises RSUs, Shares Withheld

What Happened

Guardant Health CEO Helmy Eltoukhy had restricted stock units (RSUs) convert to common shares (reported as derivative exercises).

The company withheld 1,428 shares on 2026-06-30 at $150.03 per share ($214,243) and 17,086 shares on 2026-07-01 at $170.77 per share ($2,917,776), for total withholding of $3,132,019.

Context

These were RSU vesting events (reported as derivative exercises at $0 exercise price), with the company withholding shares to cover taxes — a routine "net settlement" method, not an open-market sale by the insider.
Withholding dispositions are administrative/tax-related and do not by themselves indicate a change in the insider’s view of the company.
