Intuitive Surgical Inc (ISRG): Shares Outstanding

Annual figures by period end, from SEC filings.

Stock splits: 3-for-1, first reflected in a filing dated 2017-10-20; 3-for-1, first reflected in a filing dated 2021-10-20. Figures are as filed: per-share figures and share counts last reported before a split are on the old share basis, so changes and growth rates across a split are not shown.
