Thank you, Javier. First, I'll provide some detail on our fourth quarter and full year 2025 results and then share a detailed breakdown of our 2026 guidance. Fourth quarter adjusted operating income was $586 million, bringing full year adjusted operating income to $2.094 billion. Adjusted earnings per share from continuing operations for the fourth quarter was $3.40 with full year adjusted EPS from continuing operations of $10.78. Free cash flow was $309 million in the fourth quarter, which brings full year free cash flow to just over $1 billion. Starting with U.S. dialysis. Treatments declined about 20 basis points versus the fourth quarter of 2024. Although our total patient census growth during the quarter was as we expected, the timing of the census gain was back-end loaded in the quarter. For the full year, U.S. treatments declined by 1.1% versus 2024, in line with our expectations from the Q3 earnings call. Next, revenue per treatment growth accelerated in the fourth quarter as anticipated, up approximately $12 sequentially. Fourth quarter growth was the result of 4 primary factors: First, the resolution of aged receivables, consistent with what we forecasted on the Q3 call. Second, normal rate increases and improved yield. Third, private pay mix improved slightly after a dip in the third quarter. And finally, RPT benefited from the typical seasonal impact of flu vaccines. Full year RPT was approximately $410, up 4.7% for the year. As you think about RPT for the first quarter of 2026, keep in mind that Q1 bears a typical $5 or more RPT headwind due to patient responsibility amounts early in the year. Patient care cost per treatment increased by approximately $6 sequentially. The increase was primarily the result of seasonal increases, including health benefit costs and higher supply costs. PCCs per treatment finished the year 5.9% higher than 2024, near the top end of our revised range of expectations, but lower than our original guidance for the year. As a reminder, approximately half the year-over-year increase in PCCs was from binders in the bundle. Turning to our other segments. International adjusted OI was $21 million, resulting in full year adjusted operating income of $114 million. This reflects strong operating performance for our international business as we delivered positive organic growth and integrated the recent acquisitions in Latin America. In IKC, as Javier noted, we delivered our first profitable fiscal year. Q4 adjusted OI was $46 million and full year adjusted OI was $22 million. We saw strength across all 3 of the businesses within IKC and final reconciliations of our 2024 performance resulted in higher-than-expected shared savings revenue. Switching to capital allocation. During the fourth quarter, we repurchased 2.7 million shares, and we repurchased an additional 1.7 million shares since the end of the quarter. As is typical, a portion of these shares were repurchased from Berkshire Hathaway pursuant to the terms of our publicly filed repurchase agreement, which formulaically results in Berkshire's ownership remaining at or below 45%. For the full year 2025, we repurchased nearly 13 million shares for approximately $1.8 billion. At year-end, our leverage ratio was 3.26x consolidated EBITDA, down from the third quarter and at the midpoint of our target leverage range of 3 to 3.5x. With that, let me turn to 2026. As Javier said, we are guiding to an adjusted operating income range with a midpoint of $2.16 billion. At this midpoint, we have built in the following assumptions for U.S. dialysis. Treatment volume will be approximately flat to 2025. This assumes a flu impact consistent with what we saw in the 2023/2024 season. We are not assuming any improvement in non-flu mortality, though as Javier outlined, we are working on a number of initiatives to actively drive down mortality among our patients. Last, on admissions, we are assuming 2026 looks similar to 2025, excluding the impact of the cyber incident. To help with modeling our treatments by quarter, we have added a table to the press release showing normalized treatment days by quarter. This number adjusts for the mix of treatment days and holiday shifts, making it the most helpful number to model quarterly treatments. For example, you'll notice a year-over-year normalized treatment day headwind in Q1 2026, which drives our expectation for negative year-over-year U.S. dialysis treatment volume growth in the first quarter of this year. Moving on to RPT. For 2026, we are forecasting growth of 1% to 2%. The primary driver of this is typical rate increases. We also expect an estimated $40 million headwind from the expiration of enhanced premium tax credits for exchange plans, which is largely offset by the elimination of the $45 million headwind in 2025 from the cyber incident. We expect total U.S. dialysis costs to grow 1.25% to 2.25%, mostly driven by typical wage rate increases and G&A investments, partially offset by a decline in depreciation and amortization. The net impact of all this at the midpoint of our guidance is an increase in adjusted operating income for the U.S. dialysis business of approximately 1.5%. Also baked into the midpoint of our adjusted OI guidance range is an expectation for each of IKC and International to contribute approximately 1% to enterprise adjusted OI growth. Altogether, these results reflect our expectation for 3.2% adjusted operating income growth at the midpoint of our range versus 2025. For seasonality, we expect first quarter adjusted operating income will represent approximately 20% of our full year guidance. In other words, about $430 million at the midpoint. Below the operating income line, we expect positive other income of approximately $10 million for the year. This represents significant year-over-year improvement in this line item, resulting from no further losses from our investment in Mozarc since we have now recognized the cumulative losses equal to our investment. We expect debt expense to decline by $20 million to $40 million versus 2025. This is driven by lower interest rates year-over-year, both from the decline in rates and from our repricing and refinancing transactions, which lowered spreads. We expect noncontrolling interest to be approximately 16% of U.S. dialysis OI, and we expect effective tax rate to be in the range of 24.5% to 26.5%. Regarding capital allocation, related to Javier's comments, we announced the signing of an approximately $200 million minority investment alongside a majority investment from Ares' Private Equity Funds to acquire Elara Caring. After the transaction closes, which we expect to happen midyear, we expect this to contribute positively to our other income line. In addition, we will continue to repurchase shares in line with our typical framework, keeping in consideration our liquidity, leverage and the price of our stock relative to our view of intrinsic value. As a reminder, a significant portion of our repurchases will continue to come via direct purchases from Berkshire Hathaway as part of our ongoing repurchase agreement. At the midpoint of the range, we are guiding to adjusted EPS in 2026 of $14.30. This does not contain any unusual or nonrecurring items and is a good starting point from which to model future EPS. Our 2026 guidance represents a 33% increase over last year, which is the result of 2 familiar drivers: increased operating income and lower share count, plus the elimination of the headwind from our share of the losses at Mozarc, as I previously noted. Finally, on free cash flow, the midpoint of our guidance for 2026 is $1.125 billion, reflecting a resilient business with discipline in the deployment of our capital resources. That concludes my prepared remarks for today. Operator, please open the call for Q&A.
