On August 4, 2026, Guardant Health, Inc. insider Ian T. Clark, reporting indirect ownership via The Thornton-Clark Family Trust, exercised two stock option grants to acquire a total of 9,088 shares of common stock (2,255 shares at $91.11 and 6,833 shares at $50.57) and then sold 9,088 shares of common stock in open-market transactions at weighted average prices of $158.9816 and $158.8032 per share. The option exercises were reported as acquisitions into the trust, increasing its indirect holdings, while the subsequent sales reduced the trust’s balance to 2,975 shares of common stock. The transactions appear to be a classic “exercise-and-sell” pattern, monetizing previously vested options rather than indicating a fresh open-market purchase, with total sale proceeds of roughly $1.44 million and remaining indirect holdings valued at about $472,000 based on the reported sale prices.
