On August 12, 2026, Guardant Health, Inc. Chief People Officer Terilyn J. Monroe exercised two tranches of stock options—32,288 options at an exercise price of $20.14 and 14,012 options at $28.61—acquiring a total of 46,300 shares of common stock at those prices, and then sold 46,300 shares in a series of open-market transactions at weighted-average prices ranging from approximately $163.41 to $167.92 per share.
