For the year, Intuitive Surgical expects 15% to 17% growth in procedures using its da Vinci robotic surgery system, compared to 17% growth in 2024. That’s up from the company’s previous outlook for 13% to 16% growth. Analysts projected 15.3% procedure growth.

But the company lowered its gross profit margin forecast to a range of 65% to 66.5% of revenue, compared to 69.1% in 2024. That includes an estimated 1.7% impact from tariffs. The guidance assumes current tariffs will remain in place.

“Should additional tariffs be implemented, the adverse impact on the Company’s financial results in 2025 (including the decrease in expected non-GAAP gross profit margin) could be material,” Intuitive Surgical said in its news release.
