GUTHART GARY S

Director Gary Guthart sold 27,300 shares of ISRG for $14,475,672.47, reducing holdings by 63.5% to 15.7K shares.

Director Gary Guthart executed 3 separate sales totaling 27,300 shares for $14,475,672.47 on 2026-01-27, with a blended average price of $530.24—1.5% above the current price of $522.04. The transaction represents a substantial 63.5% reduction in his holdings, from 43.0K shares to 15.7K shares. His prior trades at ISRG show a 3-of-4 well-timed pattern at the 90-day mark (negative 90d returns of -4.0%, -3.7%, -3.8%, and one +21.5% outlier), suggesting a history of selling before near-term declines at this ticker. The 30-day and 90-day price declines of -9.3% and -1.5% respectively position this sale within his documented pattern of anticipatory exits.

Gary S. Guthart sells 22,806 shares (89.4% of holdings) for $13.0M at $570.89 on 2025-12-01

Executive Chair Gary S. Guthart executed a substantial sale of 22,806 shares (-89.4% vs pre-transaction holdings) for $13,019,721.90, reducing his stake from 25,500 to 2,694 shares. At $570.89 per share, the transaction occurred near the 52-week high of $610.45 (within 6.6% of peak) and well above the current price of $567.72. Notably, his prior trades at ISRG show mixed outcomes: two 2025-10-24 sells have delivered 30-day gains of 2.8–2.6%, while his 2025-08-29 and 2025-07-28 sales produced negative 30-day returns (-6.6% and -4.9% respectively), with 90-day results of +21.5% and +10.4%—neither marking a well-timed exit at the 90-day horizon. His cross-ticker track record (20 prior sales, 11.76% 90-day well-timed rate) provides limited insight into his reliability at this specific ticker. The stock's 90-day gain of +28.7% and strong fundamentals (revenue $2.5B, +17.2% annual growth, net income $704.4M) suggest underlying strength, yet the near-record-high exit price combined with the historical underperformance of his same-ticker timing warrants attention to the strategic context underlying this outsized reduction in founder exposure.

Guthart (Exec Chair, ISRG) sold 31,600 shares for $17.3M at $547.44 avg; retains 17.1K shares, reducing stake by 64.9%.

Gary Guthart, Executive Chair of Intuitive Surgical, executed 3 separate sales on 2025-10-24 totaling 31,600 shares for $17,299,191.94, reducing his holdings from 48,720 shares to 17,120 shares—a 64.9% reduction. The sales occurred at prices between $546.18 and $547.56, with a blended average of $547.44. Notably, at his prior 5 sales at ISRG, 0 of 4 measurable 90-day periods showed negative returns (the outcome pattern for well-timed insider sells), and his cross-ticker track record shows an average 90-day return of +9.4% after sells, indicating a pattern of selling into strength rather than ahead of declines. The stock has risen 25.0% over 30 days and 10.9% over 90 days, currently trading at $551.25, suggesting the sale execution occurred near recent momentum peaks rather than ahead of downward pressure.

Gary Guthart sold 29.4K ISRG shares at $472.49; stock down 23.2% from 52-week high and 15.9% over 90 days.

Gary S. Guthart, Executive Chair, sold 29,360 shares of Intuitive Surgical for $13.9M, reducing his position by 59.7% to 19.8K shares. The sale occurs as ISRG has declined 15.9% over the past 90 days and sits 23.2% below its 52-week high of $610.45. Guthart's prior trades at ISRG show a pattern of poorly-timed sells: his two prior measurable transactions in October 2024 yielded positive 90-day returns of 12.2% and 12.4%, meaning the stock rose after he sold. His three most recent sales on 2025-07-28 (one month before this transaction) have all posted negative 30-day returns ranging from -4.9% to -5.5%. This latest sale, occurring after significant recent stock weakness, provides a data point on insider disposition but does not yet reveal timing clarity—future price action will determine whether this transaction presaged further decline or marked a near-term bottom.

Guthart (Chair) sold 10,693 shares of ISRG for $5,322,418.81; his prior ISRG sales showed positive 90d returns averaging +12.8%

Gary Guthart, Executive Chair of Intuitive Surgical, executed 3 separate sales totaling 10,693 shares (10.7K shares) for $5,322,418.81 ($5.3M) at a blended average price of $497.75 on 2025-07-28. His post-transaction holdings remain substantial at 1,204,863 shares (1.20M shares), representing a -0.9% reduction relative to pre-transaction levels. Notably, his prior trades at ISRG showed consistently positive 90-day returns: his 5 prior sales at this ticker returned +12.4%, +12.5%, +12.2%, +15.3%, and +14.8% over 90 days—a pattern indicating stock price appreciation after his sales. The current price of $496.87 stands 18.6% below the 52-week high and -6.9% over the past 30 days. The observable context suggests this sale occurred as the stock traded near recent multi-month lows, following the prior pattern where his ISRG exits have preceded gains rather than declines.

CEO Gary Guthart sells 25,591 shares for $13,085,803.42 at ISRG, reducing stake by 56.2%

Gary Guthart, CEO of Intuitive Surgical, executed 3 separate sales totaling 25,591 shares for $13,085,803.42 on 2024-10-30, reducing his post-transaction holdings to 19,920 shares from 45,511 shares—a 56.2% reduction in his stake. The blended average transaction price of $511.34 sits near the 52-week high of $521.15, placing the sales within 1.9% of peak valuation. His prior 5 sales at ISRG showed mixed timing outcomes: 3 consecutive July 2024 sales delivered strong 90-day returns (+14.8% to +15.3%), but his January 2024 sales were essentially flat to slightly negative at the 90-day mark (+0.2% and -0.2%), yielding a 1-of-5 well-timed rate at ISRG. The stock has appreciated 3.9% over 30 days and 12.0% over 90 days since filing, diverging from his July outcomes when the stock rose notably after sales. With a P/E of 79.97 and annual revenue growth of +14.5%, the company remains growth-oriented, but the magnitude of this liquidation—more than half his holdings at elevated prices—represents a material reduction in his concentrated exposure to the company he leads.

CEO GUTHART sells 30,828 shares ($13.7M) across 3 transactions on 2024-07-30, reducing stake by -56.6%.

Gary S. Guthart, CEO of Intuitive Surgical, executed 3 separate sales totaling 30,828 shares (30.8K shares) for $13,673,996.12 ($13.7M) at prices ranging from $443.07 to $445.12, reducing his holding from 54,468 shares to 23,640 shares — a -56.6% reduction in his open position. The sale occurred near the 52-week high ($461.12), with the blended average price of $443.56 only 3.6% below the peak. Examined against his same-ticker history, Guthart's prior 5 trades at ISRG show only 1 well-timed at the 90-day mark, suggesting his sales have not consistently preceded stock declines; notably, his two most recent prior sells in January 2024 yielded modest 30-day gains (+2.8% to +3.2%) but near-flat 90-day returns (-0.2% to +0.2%). The magnitude of this stake reduction and the concentration in a single day warrant investor attention to changes in executive conviction, though the proximity to the 52-week high and lack of a strong pattern of well-timed exits at this ticker provide limited directional signal.
