Thanks, Ron, and thanks, everyone, for joining. On today's call, I'll start by providing an update on the initiatives we are actively pursuing to reduce variability and drive improved performance on a go-forward basis before reviewing our second quarter financial results. As Ron touched on, 2025 is a transition year in which we are advancing strategic initiatives that we started putting in place last year to improve our contract economics, reduce our risk and optimize our cost structure. While this is a long business cycle, we are now taking a more assertive approach for improved operational and financial performance. The increased visibility and alignment of our financial and operational data will enable us to more quickly identify and drive improvements and better manage the business. We believe we're going to start seeing the results of these changes to deliver enhanced performance in growth in 2026 and forward. As we look at our second quarter results, it is clear that a combination of factors are at play. Some of them are market-based and out of our control. Others are actively addressing through previously exited markets or reducing our exposure to Part D, and these will not reoccur in 2026. While headwinds remain, we are confident they can be addressed through better execution and a sharper focus on our operations and cost discipline. While our strategic priorities remain consistent, we are confident that with our new leadership structure, we have greater flexibility to pursue these objectives with a faster pull-through from action to outcome. I will run through the changes we are implementing and aggressive steps we are taking to set us up for improved performance one by one. First, enhancing our platform. During the quarter, we made additional progress in strengthening our network and our platform through advancements in technology, clinical pathways and operating efficiency. By more effectively leveraging data and technology, we are working to bring agilon closer to our PCP partners by providing solutions that drive higher quality of care and reduce variability and care delivery across our network. Second, data. We have significantly improved our data visibility and timeliness. Approximately 72% of our patient population is validated in our enhanced data platform, which went into effect at the end of the first quarter 2025. For those patients, we are seeing a high correlation with the final 2024 and midyear 2025 data. The high correlation of the enhanced data platform for estimating and validating cost trends and RAF scores increases our confidence in the foundation and potential for 2026 performance. In addition, in late 2024 and early 2025, we expanded the clinical depth and data of our burden of illness and quality programs while directly integrating clinical evidence and evidence-based guidelines for the physician at the point of care. These improvements are now driving an increase in early identification of high-risk conditions and potential gap closures, and we expect to make additional advancements this year. These enhanced capabilities support our expectation for improvement in 2026 for burden of illness, expanded clinical pathways and quality scores. Third, enhancing quality and delivery. Our ability to deliver top-tier quality performance relies on us leveraging the strengths of a PCP's relationship with the senior patient. Overall demand for our total care model remains strong as payers and providers look to agilon to deliver quality and clinical outcomes while reducing costs. Recent surveys support the strength and demand of the total care model with an NPS score of 85 as well as 92% PCP retention and 90% retention among MA patients. We remain committed to driving 4-plus star quality performance. Our enhanced burden of illness program provides the foundation for our clinical model through early and accurate identification, assessment and documentation of a patient's comprehensive health conditions at the PCP office. By connecting the burden of illness assessment to our quality and care delivery programs through the design and implementation of care plans, we can impact high acuity chronic disease categories like heart failure, kidney disease and dementia. Generally, high-risk patients are driving the majority of inpatient utilization. Through early identification, we are making significant progress on our clinical pathways programs by focusing on high-risk patients and seeing them more often, we can help lower costs and improve health outcomes. Starting with our heart failure program. We continue to make strong progress. While still in the early stages of implementation, we are now live in over half our markets and are seeing strong month-over-month increases in enrollment. We will provide updates on our progress in clinical outcomes later in the year. Our piloted program is now live across most of our markets. We've been pleased to see a strong increase in patients choosing to receive advanced illness management via our program. We also continue to see improved care quality indicators like a reduction in unnecessary hospital admissions compared to benchmark and increased hospice length of stay. Given the positive patient and clinical impacts to date, we're focused on expanding this program across partnerships and geographies in '25, which we expect will create additional value in 2026. Our fourth area of focus is improving our contract economics. We are currently in active negotiations with our payer partners for 2026 with approximately 50% of our membership up for renewal. We believe we can establish agreements that better align economic terms with the value delivered and predictability of performance. During this renewal process, we remain focused on several areas: first, a further reduction in Part D exposure where we are already seeing positive indications from payers; second, an expansion of quality incentives, which are aligned with payer objectives; third, improved economic terms for Part C; and fourth, a continued narrowing of the risk from supplemental benefits through better information. We are also optimistic that the recent public commentary from payers will translate to a more normalized payer bidding environment on both pricing and benefits as they focused on improved margin performance; last, we will be working to drive greater efficiency across the platform. We have launched a process to further evaluate our operating expenses to support improved profitability. Collectively, these levers that we are pulling and our focus on enhanced execution will drive performance recovery in 2026 and beyond. Before turning toward what is next, I'm going to provide the details of the second quarter results. Let me start by saying that we are clearly disappointed with our financial results for the second quarter. These results reflect a lower-than-expected burden of illness or risk adjustment contribution for both 2024 and 2025, unfavorable development in Part D costs and 2025 cost trends that are in line with expectations. Our second quarter results are meaningfully influenced by the recent introduction of our enhanced data platform, which we believe has materially improved our financial and clinical data visibility and insights for both operational execution and financial forecasting. We have further to go with more payers to add, but the data we do have indicates that the burden of illness assessment work our physician partners performed in 2024 did not yield the expected increase in 2024 and 2025 revenue. Before we provide more detail on risk adjustment, let me highlight some other key metrics. Starting with membership. Our Medicare Advantage membership at the end of Q2 2025 was 498,000 members compared to 513,000 members in Q2 2024, reflective of our measured approach to membership growth and recent market exits. As a reminder, the class of 2025 contracts are on a glide path approach and are not driving a meaningful variance in our financial results. We expect our same geography growth rate to be in line with the broader industry for 2025. ACO REACH membership in the second quarter was 116,000 members compared to 132,000 members in the second quarter of 2024 and was in line with our expectations. Turning to revenue. Total revenue for Q2 2025 was $1.4 billion compared to $1.48 billion in Q2 2024. The year-over-year revenue decrease is primarily due to lower risk adjustment in 2024 and 2025 and unfavorable development in Part D. Medical margin for the second quarter 2025 was negative $53 million compared to positive $106 million in Q2 of 2024. While medical cost trends are in line with our prior expectations, medical margin was below our guidance, driven primarily by the underperformance of our burden of illness program in 2024 and 2025 and unfavorable prior period development. We have provided a bridge in the earnings presentation we issued today that walks from the guide we provided for the second quarter 2025 to our actual results. During the second quarter, we received substantially all of the final 2024 risk adjustment data from our payer partners that indicated our 2024 risk adjustment was lower than expected. This in combination with additional payer data for 2024 Part D resulted in negative prior period development of $66 million recorded primarily as a reduction of revenue. It is important to point out several things. First, of this amount, $20 million was associated with exited markets. Second, $13 million was associated with higher 2024 Part D costs from one payer who agreed to carve out Part D beginning in 2025, leaving $37 million of risk adjustment related to 2024 activity in our existing markets. Last, because of the lower risk score step off from 2024 combined with data that we now have from our enhanced data platform, we see that our 2025 risk adjustment is also trending lower than our expectations. As a result, we have trued up our risk adjustment, resulting in a $48 million reduction in revenue. This represents the year-to-date true-up for 2025 risk scores for the 72% of our membership on the Enhanced data platform. We have not changed the estimates for the remaining members pending the receipt of midyear risk score information, which we expect late in the third quarter. Our enhanced data platform provides greater visibility and detail for both revenue and claims which we expect will continue to enhance our forecasting, including on risk adjustment. Adjusted EBITDA for the quarter was negative $83 million compared to negative $3 million in Q2 2024. The year-over-year movement reflects the items I just mentioned, partially offset by favorability from lower geography entry cost and operating cost initiatives. Adjusted EBITDA related to ACO REACH was $10 million in the second quarter of 2025, in line with our expectations. Managing medical cost trends remains a top priority. For Q2 2025, our year 2 plus markets medical cost trend was 5.9% compared to 6% in Q2 2024. MA results continue to demonstrate agilon's strong quality performance metrics with readmission, hospital admission and ER visit rates 20% to 30% better than the local fee-for-service benchmark. Primary care utilization and annual wellness visit volume remained relatively flat, and the overall medical cost trend was within our expected range for the first half of the year. As part of our strategy to manage risk, we have successfully reduced our exposure to Medicare Part D with less than 30% of our membership carrying Part D risk in 2025, and we continue to make progress to reduce it further as we enter 2026. Additionally, we are working closely with our payer partners to refine benefit designs and improve alignment on medical cost management. On the balance sheet, we ended the quarter with $327 million in cash and marketable securities and $176 million of off-balance sheet cash held by our ACO entities. We believe our current liquidity position gives us the flexibility we need to navigate this challenging period while maintaining our focus on the factors that will drive long-term performance for our business, our physician partners and our shareholders. In conjunction with the announcement of agilon's leadership change and the evaluation of additional actions to optimize our business as well as continued execution of ongoing initiatives and market uncertainty, which may impact future results, we have made the decision to withdraw our previously issued full year 2025 financial guidance and related assumptions. In summary, we are extremely focused on improving the near-term profitability of the business that will allow us to drive growth in 2026. Our actions include improving contract economics and bid visibility with payers, continuing to enhance our data platform and burden of illness program, removing variability in the business by reducing exposure to items we don't control, focus on expansion of quality programs that are aligned with our execution and continued cost discipline and capital allocation to strengthen our balance sheet. Moreover, with a positive rate environment in 2026, continued execution on our clinical and quality initiatives, and improved burden of illness performance, we believe we will significantly enhance profitability in 2026 and beyond. Finally, I want to thank our employees and our physician partners who have been working tirelessly to navigate these challenges with us. Our people are the foundation of our success and are key to our ability to execute our plan and strategic priorities. To reiterate what we have outlined today, this is a marked pace of change from how we executed the business previously. With that, operator, let's move to the Q&A portion of the call.
