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

Rhea-AI Filing Summary

Guardant Health (GH) – Form 4 filing dated 07/02/2025 discloses routine equity activity by Chief Financial Officer Michael Brian Bell linked to previously granted restricted stock units (RSUs).

• On 07/01/2025, 2,084 RSUs vested (code M). These were converted into common shares at no cash cost.
• To satisfy tax-withholding, 1,057 shares were automatically withheld and disposed of at $50.71 per share (code F).
• Net result: the CFO’s direct common-stock holdings increased by 1,027 shares to 43,028 shares; he retains 10,421 unvested RSUs.

No open-market purchases or discretionary sales occurred; the transactions appear strictly administrative and are consistent with the original three-year vesting schedule of the December 13, 2023 RSU grant.

Insights

Securities Analyst

TL;DR: Routine RSU vesting; minimal market impact.

The filing documents standard vesting of CFO Bell’s December 2023 RSU grant. Half the shares were forfeited to cover withholding taxes, a common practice that does not signal a change in sentiment. The net share accretion (≈1 k shares) is immaterial relative to Guardant Health’s ~103 m basic shares outstanding. No cash was raised or paid by the insider, so liquidity and capital-structure metrics remain unchanged. Overall, the event is neutral for valuation and governance.

Corporate Governance Expert

TL;DR: Administrative insider transaction, governance-neutral.

This Form 4 reflects automatic tax withholding under Rule 16b-3 rather than an elective sale, maintaining alignment between management and shareholders. The continued ownership of 10,421 unvested RSUs preserves long-term incentives. No red flags emerge regarding trading plans or potential misuse of material non-public information. The filing therefore has no meaningful governance implications.
