Guardant Health, Inc. reported an insider ownership change involving Roberto A. Mignone on July 21, 2026, related to the company’s common stock. The filing indicates the change was tied to restricted stock units, rather than an open-market purchase or sale. The reported award was originally granted on November 8, 2024 and vests over four years. Under the vesting schedule, 25% of the shares subject to the restricted stock unit award vested on October 21, 2025, with the remaining 75% vesting in monthly installments over the following three years. The July 21, 2026 report date appears to correspond to one of those scheduled monthly vesting events. Because the security involved was a restricted stock unit award, the filing notes that pricing information is “not applicable” for the RSUs. The provided filing text does not include the number of shares vested or acquired, a transaction code, or Mignone’s beneficial ownership following the transaction. The Form 4 was signed on July 22, 2026 by John G. Saia as attorney-in-fact for Roberto A. Mignone. The disclosure matters because it reflects continuing equity compensation vesting for an insider or affiliated reporting person at Guardant Health, aligning Mignone’s ownership with the company’s stock performance over the award’s four-year vesting period.
