Is ISRG's 20% Procedure Growth the New Normal or a Peak?
Read MoreHide Full Article
Key Takeaways
ISRG's combined da Vinci and Ion procedures up 20% YoY in Q3, accelerating from about 18% in the first half.
ISRG saw da Vinci procedures rise 19% and Ion surge 52%, aided by da Vinci 5 driving higher utilization.
ISRG flagged possible elective pull-forwards, timing benefits, and bariatric declines tied to GLP-1 adoption.
Intuitive Surgical’s (ISRG - Free Report) third-quarter results reignited the long-running debate around the durability of its growth engine. Combined da Vinci and Ion procedures rose 20% year over year in the third quarter of 2025, accelerating from roughly 18% growth in the first half. The top-line number is impressive — but the key investor question is whether this pace is sustainable or reflects a near-term peak driven by product cycles and timing effects.
On the positive side, the procedure mix underscores earnings durability. da Vinci procedures increased 19%, while Ion volumes surged 52%, with growth spanning benign general surgery, gynecology, colorectal, thoracic, and international markets. Management highlighted that da Vinci 5 is already driving higher utilization than prior-generation Xi systems, with U.S. da Vinci utilization turning positive after being flat earlier in the year. The system’s efficiency gains —higher surgeon autonomy, integrated insufflation, and workflow improvements — are enabling hospitals to absorb more volume without proportionate capital expansion, a powerful lever in a constrained operating environment.
However, management acknowledged anecdotal evidence that some elective procedures may have been pulled forward in July and August amid uncertainty around Medicare funding and insurance dynamics, even if third-party data is yet to confirm this effect. International growth also benefited modestly from holiday timing shifts, contributing roughly a one-point tailwind.
Meanwhile, bariatric procedures continue to decline at high single-digit rates, pressured by GLP-1 adoption, with surgeons unable to predict when volumes will stabilize. While bariatrics represents less than 3% of total da Vinci procedures, the category is a reminder that not all surgical demand is immune to therapeutic substitution. Additionally, hospital budget constraints — particularly outside the United States — and macro health policy shifts could temper capital and utilization momentum over time.
ISRG’s 20% procedure growth appears supported by genuine utilization and technology-driven gains; however, sustaining this pace will depend on continued da Vinci 5 adoption offsetting elective volatility and pockets of softer demand.
Peer Update
Zimmer Biomet (ZBH - Free Report) is depending heavily on its robotics strategy to drive ROSA adoption as it works to reaccelerate growth. ZBH emphasized repeatedly that ROSA is central to its differentiated “customer-centric technology suite,” pairing non-CT-based robotics with navigation tools like OrthoGrid to meet diverse surgeon needs.
In the third quarter, ZBH highlighted its strongest robotics capital quarter in over a year, with U.S. ROSA accounts performing over half of knee implants robotically, up 400 bps year to date. ZBH expects upcoming enhancements, such as ROSA with OptimiZe, featuring a simplified UI and kinematic alignment, to deepen penetration across ASCs and competitive accounts.
Stereotaxis (STXS - Free Report) is making significant progress with its GenesisX robotic surgery platform, a next-generation solution designed to expand access to robotic electrophysiology procedures. In the second quarter of 2025, Stereotaxis’ GenesisX secured CE Mark approval in Europe, and the first commercial system was manufactured, with FDA clearance expected later this year.
Initial hospital installations are planned in Europe in 2025, followed by a full U.S. and EU launch in 2026. GenesisX is engineered to avoid costly lab construction, lowering barriers to adoption. With second-quarter operating expenses steady at $6 million, Stereotaxis plans disciplined reinvestment in salesforce expansion and catheter-driven recurring revenues to support commercialization.
ISRG’s Price Performance, Valuation and Estimates
Shares of ISRG have gained 8.1% in the past six months compared with 14.8% rise for the industry.
