POTTER MYRTLE S 4

What Happened

• Myrtle S. Potter, a director of Guardant Health, reported three related transactions on June 17, 2026: (1) 2,711 restricted stock units (RSUs) were acquired upon vesting (reported at $0.00); (2) 4,203 derivative units were recorded as exercised/converted (code M) at $0.00 (acquired); and (3) the same 4,203 derivative units were recorded as disposed the same day at $0.00. No cash amounts were reported for these transactions.

Key Details

• Transaction date: June 17, 2026. Form 4 filing date: June 22, 2026 (filed 5 days after the transactions; Form 4s are typically due within two business days, so this appears late).
• Prices reported: $0.00 for all items (indicates no cash purchase price shown in the filing).
• Shares acquired: 2,711 (RSU vesting); 4,203 acquired via exercise/conversion then 4,203 disposed the same day.
• Shares owned after the transactions: Not stated in the provided filing excerpt.
• Footnotes: F1 notes the RSU award vested in full on the date of the 2026 Annual Meeting (June 17, 2026). F3 reiterates the RSU vesting timing (one-year anniversary or next annual meeting). F2 is not applicable to RSUs.

Context

• The "M" code indicates an exercise or conversion of a derivative (e.g., option or other convertible award). The filing shows those 4,203 derivative units were both converted/exercised and disposed the same day, which typically means the converted shares were immediately transferred or sold, but the filing does not state the reason (e.g., sale, transfer, or net settlement).
• Receiving vested RSUs is an acquisition (no cash outlay). Dispositions of converted derivatives can be routine (tax withholding, net settlement, or sale); this filing does not provide a motive.
