MIGNONE ROBERTO 4

What Happened
Roberto Mignone, a director of Guardant Health (GH), reported the exercise/conversion of a derivative on 2026-07-21 that resulted in 264 shares acquired and 264 shares disposed, both at $0. The filing shows no cash exchanged in these transactions; the activity reflects conversion/settlement of an equity award rather than an open-market purchase or a conventional sale.

Key Details

• Transaction date: 2026-07-21 (filed 2026-07-22) — filing appears timely.
• Transactions reported as code M (exercise or conversion of a derivative).
• Shares acquired: 264 @ $0.00 (amount reported $0).
• Shares disposed: 264 @ $0.00 (derivative disposition).
• Shares owned after transaction: not specified in the excerpt of this filing.
• Footnote F1: The RSU award was granted 11/08/2024 and vests over four years (25% vested 10/21/2025; remaining 75% vests monthly over the next three years).
• Footnote F2: "Not applicable for Restricted Stock Units."

Context
Code M indicates conversion/exercise of a derivative—here consistent with RSU vesting (see F1). The matching acquisition and disposition of 264 shares at $0 is commonly how vested RSUs are settled (for example, net share settlement or tax-withholding), and the filing does not indicate an open-market buy or a cash sale. This report is informational about award vesting/conversion and does not by itself indicate a bullish or bearish signal.
