The company, which dominates the robotic-assisted surgery market, not only delivered strong quarterly performance but also raised its full-year guidance, suggesting continued momentum in the robotic surgery sector, according to the earnings report.

Quarterly Performance Exceeds Expectations

Intuitive Surgical’s Q3 financial results were notably strong, according to the company’s release. The company achieved revenue of $2.51 billion, representing a substantial 23% increase compared to $2.04 billion in the same quarter of 2024, the report states.

Perhaps more impressively, non-GAAP earnings per share reached $2.40, vastly surpassing analyst forecasts of $1.99 and reflecting a 30% year-over-year increase from $1.84 in Q3 2024, according to the analysis.

Procedure Growth Drives Optimism

The company‘s growth appears to be primarily driven by robust procedure volume increases, according to management commentary. Global procedures utilizing both da Vinci and Ion systems reportedly increased by approximately 20% year-over-year collectively.

More specifically, da Vinci procedures rose by 19%, while Ion procedures experienced a remarkable 52% surge. Looking forward, management has elevated its full-year guidance for da Vinci procedure growth to 17-17.5%, exceeding analyst expectations of 16.4%, according to the report.

Valuation Assessment After Price Surge

Following the significant stock price increase, analysts are assessing whether ISRG shares remain reasonably valued. According to valuation metrics, ISRG stock currently trades at roughly 71 times trailing twelve-month earnings, which sources indicate is actually lower than its four-year average of 75 times.

Analysts suggest that even when considering adjusted earnings, the price-to-earnings ratio generally aligns with historical averages despite the recent uptrend. Some reports indicate that with the company forecasting superior growth rates, investors might reasonably consider a higher multiple than ISRG’s long-term average, potentially creating additional upside potential.

Historical Volatility Considerations

Despite the positive earnings report, historical data suggests ISRG stock has shown notable vulnerability during market downturns, frequently experiencing steeper declines than the broader market, according to historical performance analysis.

During the inflation shock of 2022, ISRG stock reportedly plummeted 50% from its November 2021 high to October 2022 low, compared to a 25.4% decline for the S&P 500 during the same period. Similarly, amid the COVID pandemic in 2020, ISRG stock fell 40.5% from peak to trough, versus a 33.9% decline in the S&P 500, according to market data.

Competitive Position and Future Outlook

The company’s consistent ability to exceed expectations while raising guidance reportedly showcases the strength of its competitive advantage in robotic surgery. With the accelerating adoption of the da Vinci 5 system and growing traction for the Ion platform, analysts suggest ISRG appears well-positioned to benefit from the ongoing transition toward minimally invasive procedures.

While the stock’s premium valuation necessitates ongoing successful execution, the combination of robust procedure growth, expanding market opportunities, and proven operational excellence implies that ISRG continues to be viewed as an appealing long-term investment, even after the recent surge, according to multiple analyst assessments.
