Lock-in-now is deterministic (0%). Plans that wait depend on future prices; risk is near-zero when inventory comfortably exceeds the goal. Volatility: each stack's option-implied vol if a ticker is set, otherwise 30%. Lognormal model; real markets have fatter tails.

Founded in 1995 to commercialize robotic surgery research from SRI International, the company won clearance for the da Vinci system in 2000 and built a franchise on the razor-and-blade model: hospitals buy a system, then purchase instruments and accessories that expire after a set number of uses. That recurring revenue now exceeds system sales. Surgeon training and installed base create switching costs that have held competitors off for two decades. Ion extends the platform to lung biopsy. Headquarters are in Sunnyvale, California.

Intuitive Surgical equity questions

How much ISRG stock do I sell to fund a goal without overpaying tax?
It depends on your cost basis, your target amount and date, and how the sale spreads across tax years. Selling vested ISRG shares triggers long-term capital-gains tax, plus the 3.8% net investment income tax and state tax above certain income, and bunching a large sale into one year can push the gain into a higher bracket. The calculator above builds the minimum-tax sell schedule across your lots to net your target amount by your date.
Does Intuitive Surgical grant ISOs, NSOs, or RSUs?
Equity compensation at Intuitive Surgical typically takes the form of restricted stock units (RSUs). Restricted stock units are taxed as ordinary income when they vest.
Do Intuitive Surgical RSUs use double-trigger vesting?
No. Intuitive Surgical restricted stock units (RSUs) use single-trigger vesting: each tranche becomes yours as it vests on schedule, taxed as ordinary income at that point, with no liquidity event required.
