[Form 4] Guardant Health, Inc. Insider Trading Activity

Rhea-AI Filing Summary

Guardant Health (GH) Form 4: Director Steve E. Krognes reported the automatic conversion of 154 restricted stock units (RSUs) into an equal number of common shares on 07/31/2025 (transaction code “M”). No shares were sold. The RSUs stem from an August 9 2022 grant that vested 25 % on 06/30/2023; the remaining 75 % continue to vest in equal monthly installments through mid-2026.

Following the conversion, Krognes now holds 17,973 shares directly and retains 1,698 un-settled RSUs. The transaction was priced at $0, indicating a standard equity award settlement rather than an open-market purchase. Ownership structure remains direct, and no 10b5-1 plan was indicated.

Insights

Equity Compensation Analyst

TL;DR: Small RSU vesting; negligible market impact.

The filing shows routine settlement of 154 RSUs from a 2022 grant. No cash purchase, no sales, and ownership rises marginally to 17,973 shares plus 1,698 RSUs. Because the quantity is immaterial relative to GH’s 106 M share float, signal value for investors is minimal. It does, however, reaffirm ongoing equity-based compensation alignment for an outside director, which is standard governance practice rather than a directional bet.
