Q2 Financial Summary

Gross profit, income from operations, net income attributable to Intuitive Surgical, Inc., and net income per diluted share attributable to Intuitive Surgical, Inc. are reported on a GAAP and non-GAAP* basis. The non-GAAP* measures are described below and are reconciled to the corresponding GAAP measures at the end of this release.

Second quarter 2025 revenue was $2.44 billion, an increase of 21% compared with $2.01 billion in the second quarter of 2024. The higher second quarter revenue was driven by growth in da Vinci procedure volume, higher da Vinci system placements, and an increase in the installed base of systems.

Second quarter 2025 instruments and accessories revenue increased by 18% to $1.47 billion, compared with $1.24 billion in the second quarter of 2024. The increase in instruments and accessories revenue was primarily driven by approximately 17% growth in da Vinci procedure volume and approximately 52% growth in Ion procedure volume.

Second quarter 2025 systems revenue was $575 million, compared with $448 million in the second quarter of 2024. The Company placed 395 da Vinci surgical systems, of which 180 were da Vinci 5 systems, in the second quarter of 2025, compared with 341 systems, of which 70 were da Vinci 5 systems, in the second quarter of 2024. The second quarter 2025 da Vinci surgical system placements included 193 systems placed under operating lease arrangements, of which 124 systems were placed under usage-based operating lease arrangements, compared with 175 systems placed under operating lease arrangements, of which 92 systems were placed under usage-based operating lease arrangements in the second quarter of 2024.

Second quarter 2025 GAAP income from operations increased to $743 million, compared with $567 million in the second quarter of 2024. Second quarter 2025 GAAP income from operations included share-based compensation expense of $200 million, compared with $176 million in the second quarter of 2024. Second quarter 2025 non-GAAP* income from operations increased to $947 million, compared with $754 million in the second quarter of 2024.

Second quarter 2025 GAAP net income attributable to Intuitive Surgical, Inc. was $658 million, or $1.81 per diluted share, compared with $527 million, or $1.46 per diluted share, in the second quarter of 2024. Second quarter 2025 GAAP net income attributable to Intuitive Surgical, Inc. included excess tax benefits of $33 million, or $0.09 per diluted share, compared with $36 million, or $0.10 per diluted share, in the second quarter of 2024.

Second quarter 2025 non-GAAP* net income attributable to Intuitive Surgical, Inc. was $798 million, or $2.19 per diluted share, compared with $641 million, or $1.78 per diluted share, in the second quarter of 2024.

The Company ended the second quarter of 2025 with $9.53 billion in cash, cash equivalents, and investments, an increase of $431 million during the quarter, primarily driven by cash generated from operations, partially offset by cash used in repurchases of common stock and capital expenditures.

“We’re pleased with our solid performance this quarter, highlighted by continued customer adoption of our newer and existing platforms, including da Vinci 5,” stated Dave Rosa, Intuitive CEO. “We are committed to advancing care, and helping our customers provide better patient outcomes, better patient and care team experiences, broadening access to care and decreasing the total cost of care.”

2025 Financial Outlook

The Company expects the following results for the full year of 2025:

•Worldwide da Vinci procedure growth of approximately 15.5% to 17% in 2025, compared to 17% in 2024.

•Non-GAAP* gross profit margin to be within a range of 66% and 67% of revenue in 2025, compared to 69.1% in 2024. This range includes an estimated impact from tariffs of 1.0% of revenue, plus or minus 20 basis points.

•Non-GAAP* operating expense growth of 10% to 14% in 2025, compared to 10% in 2024.

The updated range for expected non-GAAP* gross profit margin reflects the Company’s estimates of the adverse impact from tariffs that are currently in effect as of the time of this press release and assumes such tariffs remain in place. Should additional tariffs be implemented or existing tariffs be modified, the additional impact on the Company’s financial results in 2025, including the change in expected non-GAAP* gross profit margin, could be material. The ultimate effect of tariffs will depend on various factors, including the proportion of components procured and finished goods manufactured outside of the United States and the amount, scope, nature, and timing of the tariffs.

The 2025 financial outlook provided above includes forward-looking, non-GAAP financial measures, which management uses in measuring performance. We do not provide a reconciliation of non-GAAP outlook measures to corresponding GAAP measures on a forward-looking basis, because we are unable to predict with reasonable certainty the exact timing and ultimate outcome of certain items, including but not limited to legal proceedings, without unreasonable efforts. These items are uncertain, depend on various factors, and could be material to Intuitive’s results computed in accordance with GAAP. For additional information regarding the nature of these items, refer to the reconciliations of historical GAAP to non-GAAP measures included elsewhere in this release.

*About Non-GAAP Financial Measures

To supplement its consolidated financial statements, which are prepared and presented in accordance with U.S. generally accepted accounting principles (“GAAP”), the Company uses the following non-GAAP financial measures: non-GAAP gross profit, non-GAAP income from operations, non-GAAP net income attributable to Intuitive Surgical, Inc., and non-GAAP net income per diluted share attributable to Intuitive Surgical, Inc. (“EPS”). The presentation of this financial information is not intended to be considered in isolation or as a substitute for, or superior to, the financial information prepared and presented in accordance with GAAP.

The Company uses these non-GAAP financial measures for financial and operational decision-making and as a means to evaluate period-to-period comparisons. The Company believes that these non-GAAP financial measures provide meaningful supplemental information regarding its performance by excluding items such as amortization of intangible assets, share-based compensation (“SBC”) and long-term incentive plan expenses, and other special items. Long-term incentive plan expense relates to phantom share awards granted in China by the Company’s Intuitive-Fosun joint venture to its employees that vest over four years and can remain outstanding for seven to ten years. These awards are valued based on certain key performance metrics. Accordingly, they are subject to significant volatility based on the performance of these metrics and are not tied to performance of the Company’s business within the period. The Company believes that both management and investors benefit from referring to these non-GAAP financial measures in assessing its performance and when planning, forecasting, and analyzing future periods. These non-GAAP financial measures also facilitate management’s internal comparisons to its historical performance. The Company believes these non-GAAP financial measures are useful to investors, because (1) they allow for greater transparency with respect to key metrics used by management in its financial and operational decision-making, and (2) they are used by institutional investors and the analyst community to help them analyze the performance of the Company’s business.

Non-GAAP gross profit. The Company defines non-GAAP gross profit as gross profit, excluding SBC and long-term incentive plan expenses and amortization of intangible assets.

Non-GAAP income from operations. The Company defines non-GAAP income from operations as income from operations, excluding SBC and long-term incentive plan expenses, amortization of intangible assets, and litigation charges.

Non-GAAP net income attributable to Intuitive Surgical, Inc. and EPS. The Company defines non-GAAP net income as net income attributable to Intuitive Surgical, Inc., excluding SBC and long-term incentive plan expenses, amortization of intangible assets, litigation charges, gains or losses on strategic investments, tax adjustments, including the excess tax benefits or deficiencies associated with SBC arrangements and the net tax effects related to intra-entity transfers of non-inventory assets, and adjustments attributable to noncontrolling interest in joint venture, net of the related tax effects. The Company excludes the excess tax benefits or deficiencies associated with SBC arrangements as well as the tax effects associated with non-cash amortization of deferred tax assets related to intra-entity non-inventory transfers, because the Company does not believe these items correlate with the ongoing results of its core operations. The tax effects of the non-GAAP items are determined by applying a calculated non-GAAP effective tax rate, which is commonly referred to as the with-and-without method. Without excluding these tax effects, investors would only see the gross effect that these non-GAAP adjustments had on the Company’s operating results. The Company’s calculated non-GAAP effective tax rate is generally higher than its GAAP effective tax rate. The Company defines non-GAAP EPS as non-GAAP net income attributable to Intuitive Surgical, Inc. divided by diluted shares outstanding, which are calculated as GAAP weighted-average outstanding shares plus dilutive potential shares outstanding during the period.

There are a number of limitations related to the use of non-GAAP measures versus measures calculated in accordance with GAAP. Non-GAAP gross profit, non-GAAP income from operations, non-GAAP net income attributable to Intuitive Surgical, Inc., and non-GAAP EPS exclude items such as SBC and long-term incentive plan expenses, amortization of intangible assets, excess tax benefits or deficiencies associated with SBC arrangements, and non-cash amortization of deferred tax assets related to intra-entity transfer of non-inventory assets, which are primarily recurring items. SBC expense has been, and will continue to be for the foreseeable future, a significant recurring expense in the Company’s business. In addition, the components of the costs that the Company excludes in its calculation of non-GAAP net income attributable to Intuitive Surgical, Inc. and non-GAAP EPS may differ from the components that its peer companies exclude when they report their results of operations. Management addresses these limitations by providing specific information regarding the GAAP amounts excluded from non-GAAP net income attributable to Intuitive Surgical, Inc. and non-GAAP EPS and evaluating non-GAAP net income

attributable to Intuitive Surgical, Inc. and non-GAAP EPS together with net income attributable to Intuitive Surgical, Inc. and net income per share attributable to Intuitive Surgical, Inc. calculated in accordance with GAAP.
