FAQ

What insider transactions did ISRG EVP & CFO Jamie Samath report?

Jamie Samath reported equity compensation activity, including performance stock units and restricted stock units vesting into common shares, plus new RSU and PSU grants. Some resulting shares were withheld to satisfy tax obligations rather than sold in open-market transactions.

Did the ISRG Form 4 for Jamie Samath show any open-market stock sales?

The filing shows no open-market sales. Dispositions coded “F” reflect shares withheld to pay taxes tied to vesting and exercises, not discretionary selling, with remaining net shares deposited into the executive’s account.

How many performance stock units were reported by ISRG CFO Jamie Samath?

He reported 3,591 performance stock units tied to a February 28, 2023 award. The compensation committee confirmed performance achievement, and these units are scheduled to vest on February 28, 2026, subject to his continued service with Intuitive Surgical.

What restricted stock unit activity was disclosed for ISRG’s Jamie Samath?

The Form 4 shows earlier RSU awards from 2024 and 2025 converting into common shares as they vested, plus a new grant of 6,720 RSUs. RSUs vest 25% per year over four years and convert one-for-one into common stock on each vesting date.

Why were some ISRG shares withheld in Jamie Samath’s Form 4 filing?

Shares coded with transaction type “F” were withheld to cover statutory tax withholding triggered by RSU vesting and derivative exercises. This method uses part of the vested shares to pay taxes instead of requiring separate cash payments.

Does the ISRG Form 4 indicate Jamie Samath’s ownership is direct or indirect?

All reported common stock, RSU, and PSU positions are listed as directly owned. The filing does not attribute the holdings to any trust, partnership, or other entity, and there are no footnotes disclaiming beneficial ownership.
