Intuitive Surgical narrowed its 2026 da Vinci procedure-volume growth outlook on Tuesday, and its shares fell about 7% in after-hours trading. According to Sina Finance, the company expects global da Vinci procedure volume growth to be closer to the midpoint of its 14%-15% forecast range, compared with its previous range of 13.5%-15.5%. Procedure volume is a key metric because surgeries performed using da Vinci systems generate recurring sales of instruments and accessories, the company’s largest source of revenue. In the third quarter, da Vinci procedure volume grew 10% in the U.S. and 20% outside the U.S.
