SEGMENT INFORMATION

Intuitive is committed to advancing minimally invasive care through a comprehensive ecosystem of products and services. This connected ecosystem includes systems, instruments and accessories, learning, and services connected by a digital portfolio that enables actionable digital insights across the care continuum. The systems, as well as the instruments and accessories, are primarily developed and manufactured by the Company. During the years ended December 31, 2025, 2024, and 2023, domestic revenue accounted for 68%, 67% and 66%, respectively, of total revenue, while revenue from the Company’s OUS markets accounted for 32%, 33% and 34%, respectively, of total revenue. The Company manages the business activities on a consolidated basis and operates in one reportable segment.

The Company’s Chief Executive Officer is the Chief Operating Decision Maker (“CODM”). The CODM utilizes the Company’s long-range plan, which includes product development roadmaps and long-range financial models, as a key input to resource allocation. The CODM makes decisions on resource allocation, assesses performance of the business, and monitors budget versus actual results using income from operations. Net income is also a measure that is considered in monitoring budget versus actual results.

Significant expenses within income from operations, as well as within net income, include cost of revenue, research and development, and selling, general and administrative expenses, which are each separately presented on the Company’s Consolidated Statements of Income. Other segment items within net income include interest and other income, net, and income tax expense.

The Company’s long-lived assets consist primarily of property, plant, and equipment, net. As of December 31, 2025 and 2024, 80% and 83%, respectively, of long-lived assets were in the U.S. As of December 31, 2025 and 2024, no individual country other than the U.S. accounted for 10% or more of these assets.

About Segments Disclosures

Segment disclosures break a company into its reportable operating units, revealing revenue, profit, and asset allocation that consolidated financial statements obscure. Under ASC 280, segments must match how the chief operating decision maker views the business, providing a window into internal management structure and resource allocation priorities.

Key signals: compare segment margins to identify which units drive profitability and which destroy value. Watch for changes in the number of reportable segments — segment aggregation or disaggregation often coincides with strategic shifts or attempts to obscure declining performance. Intersegment elimination patterns reveal internal pricing practices. The reconciliation between segment totals and consolidated figures exposes corporate overhead allocation and unallocated items. Geographic revenue concentration highlights regulatory and currency exposure. Compare segment-level capital expenditure against segment revenue to assess where management is investing for future growth versus harvesting existing assets.
