  1. Shares issued pursuant to the three-for-one stock split of the Company's issued and outstanding common stock, par value $0.001 per share, were distributed on October 4, 2021, to stockholders of record as of September 27, 2021. All share and per-share information have been retroactively adjusted to reflect the stock split.
  1. Beginning with the quarter ended March 31, 2022, the Company is no longer adjusting non-GAAP research and development expenses, non-GAAP operating margin, non-GAAP income before taxes, non- GAAP net income attributable to Intuitive Surgical, Inc., or non-GAAP net income per share attributable to Intuitive Surgical, Inc. for charges relating to intellectual property and license arrangements expensed to R&D. The Company made these changes to its presentation of non-GAAP financial measures based on its understanding of the U.S. Securities and Exchange Commission's (the "SEC") current views on this practice from knowledge of communications between the SEC and a number of pharmaceutical and life sciences companies and independent registered public accounting firms. Historical non-GAAP measures have been adjusted for comparability.

  1. Non-GAAPgross profit margin is calculated by dividing non-GAAP gross profit by revenue.
  2. Beginning with the quarter ended March 31, 2022, the Company is no longer adjusting non-GAAP financial measures for charges relating to intellectual property and license arrangements expensed to R&D. The Company made these changes to its presentation of non-GAAP financial measures based on its understanding of the U.S. Securities and Exchange Commission's (the "SEC") current views on this practice from knowledge of communications between the SEC and a number of pharmaceutical and life sciences companies and independent registered public accounting firms. Historical non-GAAP measures have been adjusted for comparability.
  3. Non-GAAPoperating margin is calculated by dividing non-GAAP income from operations divided by revenue.
  1. Shares issued pursuant to the three-for-one stock split of the Company's issued and outstanding common stock, par value $0.001 per share, were distributed on October 4, 2021, to stockholders of record as of September 27, 2021. All share and per-share information have been retroactively adjusted to reflect the stock split.

This information is supplemental to the third quarter 2023 earnings press release issued by Intuitive Surgical, Inc., on October 19, 2023, and should be read in conjunction with that release and the Company's Quarterly Report on Form 10-Q for the period ended September 30, 2023, when filed with the U.S. Securities and Exchange Commission.

  1. About Non-GAAP Financial Measures

To supplement our consolidated financial statements, which are prepared and presented in accordance with accounting principles generally accepted in the United States ("GAAP"), we use the following non-GAAP financial measures: non-GAAP gross profit, non- GAAP gross profit margin, non-GAAP SG&A expenses, non-GAAP research and development ("R&D") expenses, non-GAAP income from operations, non-GAAP operating margin, non-GAAP income before taxes, non-GAAP net income attributable to Intuitive Surgical, Inc., non-GAAP net income per diluted share attributable to Intuitive Surgical, Inc. ("EPS"), and non-GAAP diluted shares outstanding. 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.

We use these non-GAAP financial measures for financial and operational decision-making and as a means to evaluate period-to-period comparisons. We believe that these non-GAAP financial measures provide meaningful supplemental information regarding our 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 our 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 our business within the period. We believe that both management and investors benefit from referring to these non-GAAP financial measures in assessing our performance and when planning, forecasting, and analyzing future periods. These non-GAAP financial measures also facilitate management's internal comparisons to our historical performance. We believe that 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 our business.

Non-GAAPgross profit. We define non-GAAP gross profit as gross profit, excluding amortization of intangible assets and SBC and long-term incentive plan expenses.

Non-GAAPSG&A expenses. We define non-GAAP SG&A expenses as SG&A expenses, excluding amortization of intangible assets, SBC and long-term incentive plan expenses, litigation charges and recoveries, and a gain on the sale of a business.

Non-GAAPR&D expenses. We define non-GAAP R&D expenses as R&D expenses, excluding amortization of intangible assets and SBC expenses.

Non-GAAPincome from operations. We define non-GAAP income from operations as income from operations, excluding amortization of intangible assets, SBC and long-term incentive plan expenses, litigation charges and recoveries, and a gain on the sale of a business.

Non-GAAPincome before taxes. We define non-GAAP income before taxes as income before taxes, excluding amortization of intangible assets, SBC and long-term incentive plan expenses, litigation charges and recoveries, a gain on the sale of a business, and gains (losses) on strategic investments.

Non-GAAPnet income attributable to Intuitive Surgical, Inc. and EPS. We define non-GAAP net income as net income attributable to Intuitive Surgical, Inc., excluding amortization of intangible assets, SBC and long-term incentive plan expenses, litigation charges and recoveries, a gain on the sale of a business, gains (losses) on strategic investments, adjustments attributable to noncontrolling interest in joint venture, net of the related tax effects, and tax adjustments, including excess tax benefits or deficiencies associated with SBC arrangements, a one-time tax benefit from re-measurement of certain deferred tax assets, and the net tax effects related to intra-entity transfers of non-inventory assets. We exclude a one-time tax benefit from re-measurement of certain deferred tax assets, because it is discrete in nature, and exclude 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-entitynon-inventory transfers, because we do not believe these items correlate with the on-going results of our 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 our operating results. Our calculated non-GAAP effective tax rate is generally higher than our GAAP effective tax rate. We define non-GAAP EPS as non- GAAP net income attributable to Intuitive Surgical, Inc. divided by non-GAAP diluted shares, 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 SG&A expenses, non-GAAP R&D expenses, non-GAAP income from operations, non-GAAP income before taxes, non-GAAP net income attributable to Intuitive Surgical, Inc., and non-GAAP EPS exclude items such as

Page 9 of 10

amortization of intangible assets, re-measurement of contingent consideration, SBC and long-term incentive plan expenses, 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 our business. In addition, the components of the costs that we exclude in our calculation of non-GAAP net income attributable to Intuitive Surgical, Inc. and non-GAAP EPS may differ from the components that our 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.
