Thank you, Ron, and good afternoon. As Ron stated, 2025 was a transformational year. We took significant actions focused on improving the profitability of the business, including a disciplined approach to contracting, improvements in our burden of illness program, enhancing our clinical and quality programs, meaningful cost reductions and continuing to advance strategic initiatives related to our data visibility, clinical and cost management programs. Through the execution and implementation of these initiatives, we expect to drive significant improvement in profitability in 2026 while continuing to invest in our platform and partners. As we discussed last quarter, this is supported by several underlying market and payer-related tailwinds, including the 2026 final rate notice by CMS, payer bids, which were focused on margin and our actions we took in 2025 centered on execution and profitability. For today's discussion, I will cover 3 key areas. First, I will walk through our fourth quarter and full year results and a bridge to our jumping off point for 2026. Second, I will walk through our 2026 guidance, including key assumptions, driving improved profitability. And finally, I will discuss the strength of our capital position and a more disciplined near-term growth outlook. Moving to our financial performance for the fourth quarter and full year 2025. Starting with membership. Medicare Advantage membership at the end of the quarter and fiscal year-end 2025 was 511,000 members. Our ACO REACH membership for the quarter and fiscal year-end 2025 was 114,000 members. As a reminder, membership continues to be affected by our decision to take a measured approach to growth, inclusive of previously announced market exits in a smaller 2025 class. Total revenue for the fourth quarter was $1.57 billion and $5.93 billion for full year 2025, respectively. Revenue in both reflect the impact of lower-than-expected risk adjustment revenue and previously disclosed market and payer contract exits. With respect to medical costs, we continue to see favorable development from the first half of 2025 with the respective cost trend now sitting in the mid-5% range. However, for the third quarter of 2025, we experienced elevated costs, primarily attributed to inpatient stays, including a few large discrete multimillion-dollar claims totaling $6.5 million. Based on this, we increased our medical cost trend for the third quarter of 2025 to 7.2%, up from the low 6% range we previously recorded. Given the elevated cost trend we experienced in the third quarter, along with minimal paid claims visibility at close of the fourth quarter, we took a prudent approach and recorded fourth quarter medical cost trends at 7.4%. This brings our full year 2025 cost trend to approximately 6.5%, which we believe provides a solid foundation heading into 2026. Medical margin for the fourth quarter was negative $74 million and negative $57 million for the full year. Both the fourth quarter and full year results are reflective of the elevated cost trend assumptions just discussed as well as the previously discussed risk adjustment impact. In addition, the full year results include negative $60 million from exited markets and negative $53 million from prior year development. Adjusted EBITDA was negative $142 million and negative $296 million for the fourth quarter and full year, respectively. The fourth quarter reflects the items I already highlighted, partially offset by lower geography entry costs and the benefit from continued operating cost discipline. ACO REACH was in line with our expectations. Adjusted EBITDA for the fourth quarter was negative $6 million and for the full year of 2025 was $41 million. As Ron mentioned previously, ACO REACH performance further supports our confidence in our approach, the total care model and value we bring to our partners and members. On the balance sheet, we ended the quarter with $285 million in cash and marketable securities and $91 million of off-balance sheet cash held by our ACO entities. Year-end cash was ahead of our expectations by approximately $66 million, including $34 million in permanent improvement and $32 million related to expense timing. Last, in tandem with our transformation initiatives, after the quarter, we extended our credit facility and term loan. Details were filed in an 8-K. Next, let me discuss our outlook for 2026. As I previously mentioned, we are optimistic about our ability to deliver significant growth and profitability in 2026, driven by our actions in 2025. We have provided our first quarter and full year 2026 guidance metrics in the press release and earnings presentation posted on our website for you today. We have also provided bridges in the earnings presentation that walk from our jumping off point to the full year 2026 guidance. For the full year 2026, we expect year-end membership on the agilon platform will be in a range of 525,000 to 540,000 members. This includes estimated Medicare Advantage membership of 430,000 and ACO model membership of approximately 103,000 at the midpoint. The estimated Medicare Advantage membership reflects the market exits we announced in 2025, a small amount of growth as well as the impact of our disciplined contracting. As we highlighted on our third quarter earnings call, our contracting efforts were focused on achieving positive adjusted EBITDA across all markets, which embeds our assumptions of medical cost trends, payer-specific bids, quality performance and market-specific cost structure for 2026. As a result of this disciplined profitability-focused approach, we exited several payer-specific contracts for 2026, which reduced overall Medicare Advantage membership by 50,000 members. Additionally, Medicare Advantage membership includes approximately 25,000 members in a care coordination fee structure with additional incentives tied to quality and cost performance. For the full year, we expect revenues in the range of approximately $5.41 billion to $5.58 billion. As highlighted in the slides we provided today, most of the year-over-year improvement is expected to be driven from known factors, including increased percentage of premium from our contracting efforts and payer bids, which were on average at or above the CMS benchmark rate. Combined, these are expected to create over $625 million in incremental value in medical margin in 2026. As mentioned earlier, in addition to exiting structurally unprofitable arrangements, we also reduced exposure to Medicare Part D costs to below 15% of our membership. We prioritize care coordination fee structures with performance-based incentives, more than doubling the quality incentive opportunity from 2025 for the value we deliver to our members and payers. With respect to our burden of illness program, we are confident that the enhanced data pipeline, which now includes over 85% of our members, AI advances for high-risk member identification and diagnosis in our BOI program and execution on clinical pathways are expected to deliver results over and above the final year of V28 implementation. We expect a net 40 basis point improvement year-over-year at the midpoint. As a reminder, over the last 2 years, we have more than offset the impact of the V28 implementation. Our enhanced data pipeline has shown a 99% plus correlation rate and is expected to improve the accuracy and forecasting of our risk-based revenue. With respect to cost trend, we are assuming a gross cost trend of 7.5% for 2026 as trends remain elevated and net 7% when considering the 50 basis points estimated benefit from payer bids. As we have stated previously, 2026 payer bids across our markets, on average, demonstrated payers bidding for improved profitability with benefit design changes, including increases in premiums, deductibles and maximum out-of-pocket expenses and a reduction in supplemental benefits. It's important to note that this 7.5% cost trend for 2026 comes on top of the higher cost baseline that we are now assuming for 2025, which we believe is an appropriate stance in this continued elevated cost environment. We expect medical margin to be in the range of $300 million to $350 million in 2026. This reflects the positive impact from our disciplined contracting efforts, a slight benefit from our BOI program and a more conservative cost trend assumption heading into 2026 due to the continuation of elevated medical expenses. We anticipate G&A expense of approximately $234 million, which is slightly lower than the full year 2025 and geo entry expenses of approximately $15 million. G&A expense for 2026 includes the benefit from the organizational realignment initiatives we implemented in the second half of 2025, which reduced operating expenses by $35 million, exceeding what we previously communicated. This was partially offset by employee merit and medical cost inflation and the reestablishment of incentive compensation expense, assuming a full target payout. We continue to focus on additional initiatives to optimize our cost structure and drive additional operating leverage heading into 2027. Last, adjusted EBITDA for the full year is expected to be in the range of negative $15 million to positive $15 million or breakeven at the midpoint. This includes the contribution from our ACO REACH programs, which is expected to be in the range of $20 million to $25 million. As a reminder, our ACO REACH outlook reflects announced changes to the ACO REACH program for the 2026 performance year, primarily related to a rebasing of the risk adjustment cap from 2022 to 2019. While we are confident these factors will drive improved performance, we are continuing to actively manage the business to further enhance execution across all initiatives, laying the foundation to drive improved performance beyond 2026. Finally, I will discuss our capital position, which will enable our teams to continue executing on our transformation and deliver our anticipated material year-over-year performance improvement. We expect to end 2026 with at least $125 million of cash on hand, including our ACO REACH entities. This is driven by our better-than-expected year-end cash position, combined with our current 2026 outlook. Additionally, we have extended our credit facility with our existing lenders by 2 years and currently plan to pursue a reverse stock split as indicated in our proxy filing. We believe the extension reflects the strength of our operating performance outlook and continued lender confidence in our business. Finally, I would like to address the advanced rate notice released by CMS. To reiterate, we are disappointed and believe the proposal does not adequately address the high cost and utilization trends experienced over the last several years. As Ron mentioned, after further analysis of the details provided with the advanced notice, we believe our BOI and clinical pathway initiatives will help mitigate the impact of the risk model revision and normalization factor outlined in the advanced notice. In addition, our initial analysis of the sources of diagnosis indicates we should experience minimal impact as the strength of our model is our primary care partners' physical interaction with their patients. This would set our expected baseline closer to the published effective growth rate. We will continue to analyze and monitor this release and remain hopeful that a more comprehensive and appropriate approach will be taken when final rates are released in April. In summary, we recognize that we are operating in a dynamic macro environment, including industry headwinds and regulatory changes. We have executed on a significant business transformation plan, combined with our physician-centric model and scale, we believe, positions agilon health to deliver sustainable value for patients, partners and shareholders. With that, operator, let's move to the Q&A portion of the call.
