Rosa David J.

David J. Rosa, an insider at Intuitive Surgical (ISRG), has filed 298 Form 4 transactions since 2011, and the buy column reads zero: not a single open-market purchase in fifteen years, against 513,463 shares sold or otherwise disposed of over that span. But the character of his recent activity has shifted. His last three routine option-exercise cycles — 2026-02-10 (1,436 shares exercised), 2026-06-10 (1,358 shares) and 2026-07-10 (1,910 shares, exercised twice in one filing for 3,820 total) — each paired the exercise with only a tax-withholding share surrender (code F), and no accompanying open-market sale. That's a change from the pattern seen in the two prior large exercise events: on 2025-10-24, Rosa exercised 27,000 shares and sold 24,500 of them at $547.55, and on 2025-03-05, he exercised roughly 14,625 shares and sold 8,140 at $557.58. The smaller, more frequent tranches are now being kept rather than cashed out, even as the larger periodic exercises earlier in 2025 were still substantially monetized.
