What stands out

Two insiders sold shares but ended with larger stakes, because more shares came in than were sold: David Rosa (sold 24K, 11% of starting holdings; 63K added) and Craig Barratt (sold 2.9K, 11% of starting holdings; 3.7K added).David Rosa: largest sale, Oct 24, 2025 · Craig Barratt: largest sale, Oct 24, 2025

Percentages cover 12 of 22 officers and directors. 10 are left out

Left out: Gary Guthart, Mark Brosius, Fredrik Widman and Myriam Curet (holdings couldn't be fully reconciled); Iman Jeddi, Henry Charlton, Brian Miller, Gary Loeb and Amy Ladd (most of their shares vested during the period, so a percentage would mislead); Patricia Wadors (held no vested shares at the start).

Disclosed company stock is not an insider's whole wealth.

Who sold, and how much of their stake

Officers and directors, past 12 months. Each bar is 100% of that person's own stake; not comparable between people. The stake is the vested shares held at the start of the period (Oct 9, 2025); the gold part is what they sold.

Common questions

Is the Intuitive Surgical CEO selling stock?

Yes. David Rosa sold 25K shares ($13.4M, 11% of starting holdings) in the past 12 months, all of it under a trading plan disclosed in the filings.

Why are Intuitive Surgical insiders selling?

Filings rarely give a reason, and we don't guess at one. What they show is how the sales were made: 100% of sales by value ran under 10b5-1 trading plans disclosed in the filings. A trading plan schedules sales in advance.

Are any Intuitive Surgical insiders buying?

No. Officers and directors reported no purchases in the past 12 months.

How much of their stake did Intuitive Surgical insiders sell?

About 8.7% overall. As a group they ended with more shares than they started with. These figures leave out Gary Guthart, the largest holder (holdings couldn't be fully reconciled). That covers the 12 months to Oct 9, 2026 and counts vested shares reported on SEC Forms 3, 4 and 5, which is not an insider's whole wealth.

For 4 we show sales but not holdings; the ! icon on their rows explains why. Percentages cover 12 of 22 officers and directors. Left out: Gary Guthart, Mark Brosius, Fredrik Widman and Myriam Curet (holdings couldn't be fully reconciled); Iman Jeddi, Henry Charlton, Brian Miller, Gary Loeb and Amy Ladd (most of their shares vested during the period, so a percentage would mislead); Patricia Wadors (held no vested shares at the start). "Still held" compares ending with starting vested shares; a plus sign means the holding grew.

What explains the selling$91.0M of sales by plan status, purpose, seller and month

Officer and director open-market sales: $91.0M across 171,418 shares. Plan status and stated purpose are separate questions, and a sale can have both.

By plan status

Disclosed plan · $91.0M · 100%

Taxes

77,143 shares ($38.6M) were withheld by the company for taxes, which isn't a market sale.

Charitable gifts · 5.5K shares

Gifts the filings describe as charitable. Gifts are not sales and are not included in the sale totals.

Is this normal? Selling year by year5 earlier years to compare with

Less than usual: about half of the 5-year average. 12 insiders sold; the average is 12 a year.

Open-market sales (Form 4 code S) by people who were officers or directors, in split-adjusted shares. Earlier years include people who have since left. A sale that an outside holder also reports (a family trust, a fund) is counted with outside holders in every year. Shares, not dollars, are compared, so a change in the stock price doesn't look like a change in selling. Years the filings don't fully cover are shown but left out of the average.

Known gaps and uncertainty4 insiders whose holdings couldn't be fully reconciled

Inferred typo: the share class "Conmon Stock" is treated as the same class as "Common Stock" on 1 holding line, because the two spellings are nearly identical and each balance carried over exactly. Example (Susan Barnes, 1,781,019 shares): old title, new title

Inferred typo: the share class "CommonStock" is treated as the same class as "Common Stock" on 1 holding line, because the two spellings are nearly identical and each balance carried over exactly. Example (Richard Kramer, 13,500 shares): old title, new title

Inferred typo: the share class "Connon Stock" is treated as the same class as "Common Stock" on 1 holding line, because the two spellings are nearly identical and each balance carried over exactly. Example (Lonnie Smith, 3,654,000 shares): old title, new title

Sources and methodology1,603 filings from SEC EDGAR, and how we read them

All 1,603 Forms 3, 4 and 5 filed for Intuitive Surgical (SEC CIK 1035267) from Jul 3, 2003 to Sep 16, 2026, retrieved from SEC EDGAR on Oct 9, 2026. Prices are the ones reported in each filing, often weighted averages.

Probable 3-for-1 stock split on or before Oct 6, 2017 (split date stated in a footnote). Splits aren't reported as transactions; 13 holding lines changed by exactly this ratio, so earlier share counts are restated.

Probable 3-for-1 stock split on or before Oct 5, 2021 (split date stated in a footnote). Splits aren't reported as transactions; 14 holding lines changed by exactly this ratio, so earlier share counts are restated.

Holdings. Each holding line (a share class plus an owner, such as a trust or LLC) carries its last reported balance forward. Entities first reported during the period start at zero, so transfers between an insider's own trusts don't count as selling. Lines not reported for three years or more are listed separately and left out of totals.

Sales. A sale counts as under a 10b5-1 plan if its footnote cites one or the filing's Rule 10b5-1 box is checked, and as tax-related if its footnote cites tax obligations or sell-to-cover. Shares withheld by the company for taxes are listed separately. Sales with neither attribute are labeled "no plan disclosed".
