Good afternoon. I will describe our performance on a non-GAAP or pro forma basis, and I will also summarize our GAAP results later in my remarks. A reconciliation between our pro forma and GAAP results is available on our website. To facilitate a deepening of understanding of the trends within our Ion business, we have added disclosures to the data tables posted on our website. All references to total procedures and their related growth rates include da Vinci and Ion procedures taken together. Q4 and 2025 revenue procedures and system placements are in line with our preliminary press release on January 14. I will briefly review full year 2025 performance before describing our Q4 results in greater detail. 2025 financial performance was strong. Total procedures grew 19% and total revenue grew 21%. Despite the impact of tariffs, pro forma operating margin improved approximately 70 basis points to 37% for the year. Given the strong financial performance, 2025 pro forma EPS increased 22%, marking the third consecutive year of pro forma EPS growth above 20%. Consistent with our financial objectives for 2024, we saw a significant increase in free cash flow to $2.5 billion, up from free cash flow of $1.3 billion in 2024, driven by increased profitability and lower capital expenditures. During the year, we repurchased $2.3 billion of Intuitive's stock at an average price of $478 per share. Turning to Q4. Total procedure growth was 18%, driven by general surgery in the U.S. and broad-based growth in OUS markets. In quarter 4, revenue grew 19% to $2.87 billion with recurring revenue higher by 20% to $2.3 billion, accounting for 81% of total revenue. On a constant currency basis, revenue growth was 18%. Pro forma operating margin was 37%, which included an impact of approximately 95 basis points from tariffs and a $70 million contribution to the Intuitive Foundation. The strength of our financial results reflected continuing global expansion and procedure adoption of our da Vinci 5, Ion and SP platforms. For our da Vinci business, procedures grew 17%, the installed base of da Vinci systems increased by 12% to just over 11,100 systems and average system utilization increased by 4%. For our Ion platform, we continue to see robust clinical growth with procedures increasing 44%, the installed base up by 24% to just under 1,000 systems and average system utilization increasing by 11%. In the U.S., total procedures increased 16%, reflecting 15% growth in da Vinci procedures and 41% growth in Ion procedures. da Vinci procedures performed after hours, a proxy for acute care, increased by 35% in Q4, primarily driven by cholecystectomy and appendectomy procedures and reflects our support for customers who are expanding access to da Vinci surgery. da Vinci utilization in the U.S. increased 3% in Q4, driven by continued adoption of da Vinci 5, where customers are leveraging the system's efficiency advantages to increase cases performed per day. Over the past few years, our customers have increased their efforts to distribute surgeries across different sites of care from hospitals to hospital outpatient departments to ambulatory surgery centers or ASCs. Minimally invasive surgery has helped enable this shift. As this occurs, we have increased our efforts to expand our footprint in ASCs, which we expect to be a multiyear effort. Our initiative currently leverages our XiR system and its associated ecosystem with economic and capital acquisition offerings we believe are well suited to meet the clinical and financial needs of this environment. Not all ASCs run at the same volume, but with the same mix of procedures and we have started our efforts focused on higher-volume ASCs that can sustain a robotic program. Approximately 70% of the ASC procedure opportunity is in ASCs affiliated with our existing IDN customers where a number of surgeons are already da Vinci trained. In addition, we actively support customers that upgrade to da Vinci 5 in their efforts to slide their existing Xi to the HOPD or ASC setting. Outside the U.S., in quarter 4, total procedures grew 22% and on a day-adjusted basis, total OUS procedure growth was 23%. da Vinci procedures grew 21% in OUS markets, reflecting strong results in Canada, India, Korea and distributor markets and solid growth in Germany, the U.K., Italy, Spain and Taiwan. Consistent with the last quarter, procedure growth in Japan was a little lower than our expectations, reflecting lower capital placements over the last several quarters. The Japanese Ministry of Health, Labour and Welfare is currently in the final stages of evaluating granting reimbursement for additional robotic procedures starting in June of 2026. We will provide an update on the outcome on our next earnings call. Taking OUS markets combined, benign general surgery procedures increased 27%, driven by cholecystectomy and hernia repair. Globally, we continue to see strong procedure growth for our SP platform at 78% for Q4 with strength in Korea and continuing strong early-stage growth in Europe, Japan and Taiwan. In the U.S., SP average system utilization accelerated, growing 21% as compared to quarter 4 of last year. We also see encouraging initial growth in thoracic procedures following clearance in 2024 and positive customer feedback on the limited launch of our SP stapler. As a result of our clinical performance, total I&A revenue in quarter 4 grew 17% to $1.7 billion, relatively consistent with overall procedure growth. da Vinci I&A revenue per procedure was approximately $1,850 compared to $1,860 last year, primarily driven by customer ordering patterns. We also continue to see downward pressure from lower bariatric procedures and higher cholecystectomy procedures, offset by higher SP procedures and da Vinci 5-specific I&A. For our Ion platform, I&A revenue per procedure was approximately $2,200, relatively consistent with prior periods. Turning to capital performance and starting with our da Vinci business, we placed 532 da Vinci systems in quarter 4, an 8% increase from the 493 systems placed in the same quarter last year. 303 of the 532 placements were da Vinci 5, including 43 in OUS markets following recent clearances in Europe and Japan. The installed base of da Vinci systems is now 1,232 systems, used by over 10,000 surgeons since the launch of da Vinci 5. We saw 146 trade-in transactions in Q4, up from 62 a year ago, primarily driven by U.S. customers upgrading to da Vinci 5. In the U.S., we placed 304 systems, up from 204 -- 284 last year driven by adoption of da Vinci 5. Outside the U.S., we placed 228 systems compared to 209 last year. OUS placements included 118 in Europe, 40 in Japan and 17 in China compared to 89, 43 and 20, respectively, last year. We continue to see government budget challenges in Japan and the U.K. and robotic competition in China intensified in Q4, where we saw provincial tenders express preference for local suppliers and lower pricing impacting our win ratio in the quarter. Within the 532 da Vinci placements, we placed 35 SP systems in Q4, higher than the 30 systems last year, driven primarily by OUS markets. For our Ion platform, we placed 42 systems in Q4 compared to 69 systems last year, including 6 systems placed in OUS markets. Lower Ion placements in the U.S. continue to reflect a joint focus with our customers on increasing utilization in the U.S. increased by 11% in Q4. Given our capital performance, quarter 4 systems revenue grew 20% to $786 million. For our da Vinci business, leasing represented 47% of da Vinci placements, as compared to 54% last quarter and 45% last year, driven by the mix of customers who prefer to purchase. However, over time, we continue to expect the proportion of systems placed under operating lease arrangements to increase, primarily driven by OUS customers. da Vinci leasing revenue increased 34%, reflecting a 15% expansion of the installed base under operating lease arrangements and a 13% increase in lease revenue per system driven by a higher mix of da Vinci 5 systems. The average selling price for purchased da Vinci systems was $1.68 million in Q4 as compared to $1.6 million last year, driven by a higher mix of da Vinci 5 systems and a higher mix of dual-console systems, partially offset by higher trade-ins. Lease buyout revenue was $39 million as compared to $22 million last quarter and $28 million last year. Quarter 4 service revenue increased 21% to $422 million, reflecting an increase of the da Vinci installed base of 12% and the Ion installed base of 24%. Service revenue per system for our da Vinci installed base increased 7% year-over-year, primarily reflecting a higher mix of da Vinci 5 systems. Turning now to the rest of the P&L. Pro forma gross margin for the quarter was 67.8%, down from 69.5% in Q4 of last year. The year-over-year decline reflects a 95-basis-point impact from tariffs, higher facility costs, a greater mix of lower-margin da Vinci 5 and Ion revenue and higher service costs related to da Vinci 5, partially offset by product cost reductions and purchase component savings. Quarter 4 pro forma operating expenses increased 16% year-over-year driven by a $70 million donation to the Intuitive Foundation, increased head count, higher variable compensation costs and increased facility costs, partially offset by lower legal expenses. We added approximately 200 employees during the quarter, primarily in our core commercial and engineering functions. The increased donation to the Intuitive Foundation as compared to the $45 million donated in quarter 4 of last year reflects our decision to make a multiyear donation given the impact of new U.S. tax rules effective in 2026. With respect to our plans to go direct in Italy, Spain and Portugal, we currently expect to close by the end of Q1, resulting in the transfer of approximately 250 employees. Pro forma other income was $86 million for the quarter as compared to $93 million last quarter, reflecting lower interest income. Our pro forma effective tax rate for quarter 4 was 20.6%, slightly below our expectations, driven by $11 million in net discrete benefits primarily related to releases of tax reserves due to statute of limitation expirations and other various adjustments to our tax reserves. Pro forma net income for the fourth quarter was $914 million, compared with $805 million last year. Pro forma earnings per share was $2.53 per share as compared to $2.21 per share in quarter 4 of last year. Now turning to our GAAP results. GAAP net income for the quarter was $795 million or $2.21 per share compared to $686 million or $1.88 per share in Q4 of last year. The differences between our pro forma and GAAP results are outlined and quantified on our website. We ended the year with $9 billion in cash and investments, up from $8.4 billion last quarter driven primarily by cash from operations, partially offset by stock repurchases of $201 million and capital expenditures of $155 million. With that, I'll turn it over to Dan to discuss recent clinical publications and our outlook for 2026.
