Ladd Amy L 4

What Happened

• Amy L. Ladd, a director of Intuitive Surgical (ISRG), recorded derivative activity and a grant on 2026-04-30. The Form 4 shows an exercise/conversion (transaction code M) of 531 derivative units (acquired at $0.00) and a corresponding disposition entry for 531 derivative units (also $0.00). Separately she was granted 554 restricted stock units (RSUs) (transaction code A) at $0.00. The filing reports no cash paid for these entries.

Key Details

• Transaction date: 2026-04-30. Transaction codes: M = exercise/conversion of derivative; A = award/grant.
• Exercise/conversion: 531 shares @ $0.00 (acquired) and a concurrent 531-share derivative disposition @ $0.00.
• Grant: 554 RSUs @ $0.00 (acquired).
• Shares owned after transaction: not specified in the filing.
• Footnote: The 554 RSUs vest 100% on the earlier of one year after grant or the next Annual Meeting of Stockholders, subject to continued service.
• Filing timeliness: Reported with the same period date (timely file); no late filing indicated.

Context

• This is not an open-market purchase or sale. The M-code entries reflect conversion/exercise of a derivative instrument; the paired acquisition and disposition entries often reflect internal conversion/settlement mechanics rather than an outright sale. The A-code grant is an RSU award that will vest per the noted schedule and does not represent immediately tradable shares until vesting. As always, these kinds of awards are routine compensation/vesting events and should be interpreted accordingly.
