ABB vs ISRG: How ABB Ltd and Intuitive Surgical Compare (2026)
Last updated July 2026
Short answer
ABB (ABB Ltd) and ISRG (Intuitive Surgical) share investment themes but are different businesses. The right pick is whichever thesis you actually believe, sized so you are not over-concentrated in one theme.
Before you buy: how ABB and ISRG affect your concentration
The metrics above tell you which is the marginally better business. The bigger risk for most people is not picking the slightly worse stock, it is over-concentrating. ABB and ISRG share themes, so owning both, or adding either to what you already hold, can quietly push a large share of your portfolio into one bet.
This is the part a generic comparison page cannot answer, because it depends on what you own. Connect your brokerage and Walnut shows your real, combined ABB and ISRG exposure, flags overlap with your existing positions, and tells you if adding one would tip you past a concentration you are comfortable with, read-only by default, with your login staying at your broker. Walnut is not an investment adviser.
What does ABB Ltd (ABB) do?
ABB Ltd is a global technology company headquartered in Zurich, Switzerland, that builds the hardware and software behind electrification and automation. Its business spans low- and medium-voltage electrical products, switchgear and building systems (Electrification), electric motors, drives and traction (Motion), and control systems, measurement and industrial software (Process Automation). Historically it also ran a Robotics division, but in 2025 ABB agreed to divest that unit to SoftBank Group for an enterprise value of roughly $5.4 billion, moving the company to three reporting business areas. ABB reports in US dollars, sells into utilities, data centers, manufacturers, transport and infrastructure customers worldwide, and competes with the likes of Siemens, Schneider Electric and Rockwell Automation.
What does Intuitive Surgical (ISRG) do?
Intuitive Surgical (ISRG) is the dominant maker of robotic-assisted surgery systems, best known for the da Vinci platform used in minimally invasive procedures across urology, gynecology, general surgery, and other specialties. Its business model is razor-and-blade: Intuitive sells or places the large capital systems, then earns high-margin recurring revenue from the single-use instruments and accessories consumed in each procedure, plus service contracts. As the installed base of systems grows and procedure volumes rise, recurring revenue compounds. The company has expanded its platform with newer systems (including the da Vinci 5 and the Ion platform for lung biopsy), and benefits from surgeon training, hospital workflow integration, and a large library of validated procedures that create high switching costs. Intuitive went public in 2000 and is headquartered in Sunnyvale, California. It is the clear leader in surgical robotics with a wide moat, strong margins, and consistent procedure-volume growth, though it trades at a premium valuation that reflects those qualities.
ABB vs ISRG: how do they differ?
Both fit overlapping themes, but they are not interchangeable. The useful comparison is which set of drivers and risks you want exposure to.
- ABB drivers: Electrification and grid demand; Automation and energy-efficient motion.
- ISRG drivers: Razor-and-blade recurring revenue; Installed base and switching costs.
Which fits which kind of investor
A faster-growing, richer-valued name usually swings harder, so it suits a longer horizon and a higher tolerance for volatility; a steadier, more cash-generative business suits a more conservative or income-minded investor. The honest test is which set of risks you could hold through a drawdown: ABB is a cyclical industrial whose orders and revenue track global capital spending, so a slowdown in manufacturing, construction or utility investment would pressure growth. For ISRG, iSRG trades at a premium valuation, so any slowdown in procedure growth, system placements, or margins can compress the multiple sharply.
ABB or ISRG: which should you pick?
ABB vs ISRG: the full fundamentals
ABB. ABB posted a record 2025, with revenue up about 9% to roughly $33 billion, orders up about 17% near $37 billion, and net income up about 20% to around $4.7 billion. The stock trades at a premium, with a trailing P/E in the mid-30s and a forward multiple near 30, reflecting strong returns on capital (ROE near 29%) and secular demand. Figures are approximate and drawn from ABB's FY2025 disclosures and market data as of mid-2026.
ISRG. Intuitive trades at a high earnings multiple that reflects its dominant market position, high-margin recurring revenue, strong balance sheet, and consistent procedure-volume growth. The premium is the central debate: bulls justify it with the durability of the razor-and-blade model and a long runway, while bears point to multiple-compression risk if procedure growth slows or competitors gain share. Figures are approximate and should be verified against the latest filing.
Headline figures (approximate, JULY 2026): ABB shows revenue (fy2025) ~$33.2B, orders (fy2025) ~$36.8B, net income (fy2025) ~$4.7B, operational ebita margin ~19%; ISRG shows revenue (ttm) ~$8 to 9 billion (verify), recurring revenue share ~80%+ from instruments, accessories, and service, operating margin ~30% (strong), gross margin ~65% to 68%.
The bottom line: ABB vs ISRG
ABB and ISRG are related but distinct: same themes, different businesses and risks. Neither wins in the abstract; the right pick is whichever thesis you actually believe, sized so you are not over-concentrated in one theme. Walnut can show your combined ABB and ISRG exposure against your real portfolio. It is not an investment adviser.

FAQ
What is the difference between ABB and ISRG?
+
ABB Ltd is a global technology company headquartered in Zurich, Switzerland, that builds the hardware and software behind electrification and automation. Intuitive Surgical (ISRG) is the dominant maker of robotic-assisted surgery systems, best known for the da Vinci platform used in minimally invasive procedures across urology, gynecology, general surgery, and other specialties. They show up together because they share investment themes, but they are different businesses, so the better fit depends on which thesis you are expressing.
Is ABB or ISRG the better stock?
+
Neither is universally better; they suit different views and risk levels. Walnut is informational, not investment advice. Compare what each does, the tie-breaker metrics above, and the risks, then decide which fits your thesis and what you already own.
Which is cheaper, ABB or ISRG?
+
A lower multiple is not automatically the better buy: a richer valuation can be justified by faster growth, and a lower one can reflect real risk. Weigh the multiple against how fast each business is compounding.
Should you own both ABB and ISRG?
+
Because they share themes, owning both concentrates you in that theme. That can be intentional (a focused bet) or accidental (less diversification than it looks). Walnut can show your combined exposure across both, and whether adding either over-concentrates you, before you buy.
What are the risks of ABB vs ISRG?
+
ABB: ABB is a cyclical industrial whose orders and revenue track global capital spending, so a slowdown in manufacturing, construction or utility investment would pressure growth. As a Swiss company reporting in US dollars with sales across many currencies, results are exposed to foreign-exchange swings and to macro shocks in Europe, China and the Americas. The shares trade at a premium valuation that assumes continued margin strength and secular demand, leaving limited downside cushion if growth disappoints. Execution risk around the Robotics divestiture, supply-chain disruption, and intense competition from Siemens, Schneider Electric and others could all weigh on returns. Tariffs, geopolitical tension and project delays in large infrastructure and process customers add further uncertainty. ISRG: ISRG trades at a premium valuation, so any slowdown in procedure growth, system placements, or margins can compress the multiple sharply. Competition is intensifying as Medtronic, Johnson & Johnson, and others develop rival surgical-robotics platforms that could erode Intuitive's dominance over time. Hospital capital budgets are cyclical and can defer system purchases in tight economic periods. Reimbursement changes, regulatory scrutiny of new systems, and any safety or recall issues are risks. The company is also exposed to global healthcare-spending trends and currency, and the high valuation leaves little room for execution missteps.
