MIGNONE ROBERTO 4

What Happened

• Roberto Mignone, a director of Guardant Health (GH), had derivative shares converted and a restricted stock unit award reported on June 17, 2026. The Form 4 shows an exercise/conversion of 4,203 derivative shares at $0.00 (acquired) and the simultaneous disposition of 4,203 derivative shares at $0.00. In addition, he was credited with a grant/award of 2,711 shares (RSUs) at $0.00.
• The reported dollar amounts are $0.00 for each line (common with RSU vesting/settlement entries). Net from these entries, Mignone’s holdings increased by 2,711 shares (4,203 converted then disposed; 2,711 newly acquired).

Key Details

• Transaction date: June 17, 2026; all transactions reported at $0.00 per share.
• Transaction codes: M = exercise/conversion of derivative (4,203 shares); A = grant/award (2,711 RSUs).
• Shares owned after the transaction: not specified in the provided filing.
• Footnotes from the filing:
  • F1: A restricted stock unit award vested in full on the company’s 2026 Annual Meeting (June 17, 2026).
  • F2: Not applicable for Restricted Stock Units.
  • F3: A restricted stock unit award is scheduled to vest in full on the one‑year anniversary of the grant date (June 17, 2026) or the next annual meeting, whichever is earlier.
• Filing timing: Report filed June 22, 2026 for transactions dated June 17, 2026 — this appears later than the typical two-business-day Form 4 deadline.

Context

• This filing reflects equity award/vesting activity rather than an open‑market purchase or a discretionary sale. The M-code entries indicate conversion/exercise of derivative awards, and the A-code entries indicate RSUs granted or vested.
• Because the filing reports $0.00 for the transactions, these entries are consistent with RSU settlement/vesting mechanics (not an out‑of‑pocket purchase). Such awards are routine compensation for insiders and do not necessarily signal a buy/sell opinion by the insider.
