Joyce Meghan V. 4

What Happened

• Meghan V. Joyce, a director of Guardant Health (GH), had a restricted stock unit (RSU) award vest in full on June 17, 2026 (the company's 2026 Annual Meeting). The filing shows a conversion/exercise of a derivative resulting in 4,203 shares being acquired at $0.00 and a corresponding derivative disposition of 4,203 units at $0.00. This reflects RSU vesting/conversion to common stock rather than an open-market purchase or sale.

• Shares owned after the transaction: not specified in the filing.
• Footnotes: F1 notes the RSU award vested in full on June 17, 2026; F2 states "Not applicable for Restricted Stock Units."

Context

• This filing documents RSU vesting and conversion into common shares (recorded as a derivative conversion), not an open-market sale or purchase. Such vesting is a routine compensation event and does not by itself indicate the director is buying or selling shares for investment reasons.
