Thanks, Evan. Good afternoon and thank you for joining us. On today's call, I will provide you with an overview on: one, our fourth quarter and full year 2024 financial results and our 2025 guidance; two, investments we are making to further enhance our clinical strategy and capabilities; and three, actions and programs we are implementing to reduce certain business risks that lie outside our control, enhance our operational execution and drive improved performance going forward. But I'd like to begin with some context on the trajectory of our business as we continue to take actions to manage through the third year of a difficult Medicare Advantage rate and utilization cycle. While the 2025 macro environment continues to be challenging, we enter this year with a laser focus on strengthening our business for near-term improvement, success and profitability. In 2024, we took actions to: one, reduce our underwriting exposure to costs outside our control, such as a reduction in Medicare Part-D exposure to less than 30% of our membership; two, pursue profitable and measured growth aligned with current payor and provider dynamics which is reflected in both our reduced 2024 membership step-off and a smaller revised 2025 partner class; three, strengthen our core clinical and operational capabilities to reduce variability and enhance quality outcomes; and four, maintain operating cost discipline by further leveraging our scaled infrastructure and technology investments. We intend for this focused approach to continue in 2025. And despite the near-term headwinds, our goal is to be cash flow breakeven by 2027. With respect to those 2025 headwinds, the Medicare Advantage market continues to experience an elevated cost trend, while managing through the ongoing transition to V28, changes related to the Inflation Reduction Act and increased quality bonus thresholds, all of which are embedded in our '25 outlook. Our ability to weather this down cycle in Medicare Advantage and differentiate on the management of medical costs and quality outcomes relative to the fee-for-service alternative should position us well with health plans and physicians as the rate and cost spread ultimately corrects. With that said, the recent favorable trends in payor bids and the 2026 advanced notice from CMS make us optimistic that we will see a more favorable overall environment for '26 and beyond. Now, let me provide a quick overview of our fourth quarter and full year results and our guidance for 2025. Note that Jeff will provide more details in his remarks later in the call. For the fourth quarter, MA membership continued its growth trend and was in line with our expectations, increasing 36% or 138,000 members year-over-year to 527,000 members, driven by the continued expansion of our '24 partner class and 4.1% same geography growth. ACO model membership was 132,000 members, slightly ahead of our expectations. Total revenue grew 44% to $1.52 billion in the quarter and $6.06 billion on the year. Growth was primarily driven by the class of '24 and organic growth in our existing classes, partially offset by higher costs associated with Medicare Part-D and lower risk adjustment revenue related to unfavorable prior-period development for the full-year. Medical margin was $1 million in the quarter and $205 million for the year which when adjusted for a $5 million reserve for estimated 2025 losses from partnerships we intend to exit this year was at the low-end of our guidance range. In the quarter, we also recorded elevated Medicare Part-D prescription drug and supplemental benefit costs, partially offset by favorable medical cost development from Q1 and Q2. It should be noted that $6 million of the higher Medicare Part-D costs in the quarter are tied to payor contracts in which Part-D risk is carved out, starting in 2025. Adjusted EBITDA was minus $84 million for the quarter and minus $154 million for the year which came in at the low end of our guide. The quarter reflected lower medical margin due to the aforementioned items, lower ACO model contract performance isolated to 1 partnership that we will be exiting for 2025 and favorable operating cost leverage. Now turning to full year 2025 guidance. Based on current market dynamics, we have made a strategic decision to constrain our 2025 MA membership to balance near-term risk and opportunities. And we now anticipate a full year MA membership decline of approximately 4% or 22,000 members to a range of 490,000 to 520,000 or 505,000 at the midpoint. This year-over-year change includes; adding 20,000 members in a smaller class of 2025 from 3 new partners, same geography growth of 3% or 13,000 members and a reduction of 54,000 members from previously disclosed partnership exits, multiple December 2024 payor contract terminations and tighter attribution management with health plans. Similarly, our ACO model business which has been an area of strength, will see 2025 membership projected at 110,000 members as we exit 1 underperforming MSSP partnership. Revenue is forecasted to decline 2% to $5.925 billion, driven by the impact of the above mentioned membership decline, offset by a better revenue yield, inclusive of improved payor contracts, member mix changes and 2025 payor bid impact. Medical margin is expected to improve 46% to $300 million at the midpoint which reflects a slightly lower jumping off point from what we communicated in November and our view of an elevated cost trend continuing in 2025. Finally, 2025 adjusted EBITDA guidance is expected to be minus $75 million at the midpoint which assumes a gross medical cost trend of 6.3%, in line with our '24 experience and a series of offsetting strategic actions noted above. Jeff will provide more specific details on the impact of our actions, market trends and growth priorities embedded in our '25 guide. While the outlined actions are anticipated to provide incremental benefit in 2025, we expect they will be more fully reflected in our '26 performance, supporting a potential reacceleration of medical margin and adjusted EBITDA growth. Now let me provide some color on the focused investments we continue to make in what we see as a differentiated set of clinical and quality programs. Our ability to manage cost trends relative to a benchmark and deliver top tier quality performance fully relies on our ability to leverage the strength of a PCP's relationship with the senior patient. Current MA results show our readmission, hospital admission and ER visit rates 20% to 30% better than the local fee-for-service benchmark and quality scores for each year 2 plus market approaching or greater than 4.25 stars. This level of quality performance reinforces our value to payors and is reflected in 2025 payor contracts with increased incentives tied to delivering 4-plus stars performance. Similarly, ACO REACH results show our network as a top performer in terms of quality and medical cost management, with the most recent period delivering $150 million or 13% in gross savings, beating the national overall cost trend by approximately 280 basis points. To extend our impact on these key metrics and drive stronger, more consistent performance, we continue to advance our clinical strategy. Specifically, with our physician partners, we are better connecting opportunities across our burden of illness, quality and care delivery programs to drive best-in-class medication adherence, further address advanced illnesses like palliative care and target significant high-acuity chronic disease categories like heart failure, dementia and COPD, in which the primary care physician is positioned to intervene earlier with the goal of preventing disease progression, alleviating symptom burden and avoiding unnecessary ER and inpatient utilization. In addition to continuing to invest in our clinical strategy, we continue to be tightly focused on the block and tackle elements of our business to improve operating performance and reduce variability around the following key components. First, we are focused on measured growth as a controllable lever across existing and new geographies with a smaller 20,000 member class of 2025. In addition, for certain new partners in '25, we have taken a glide path approach with select payors via year 1 agreements with a no downside in care coordination fee structure. Second, our payor strategy is focused on minimizing risk for elements outside our control, like Part D and supplemental benefits and maximizing reward for areas within our control, like quality performance and Part C medical cost management, where we perform well. For January 2025, we successfully repriced 40% of our membership with improved percentage of premium economic terms, including incentive dollars tied to our partners' quality performance, while reducing our Part D exposure to less than 30% of our '25 membership. Third, we are enhancing our core clinical strategy and capabilities to improve quality outcomes and accelerate performance. This includes leveraging our investments in software and AI technology, physician education and coaching content and practice and an expanded team of regional medical directors. And fourth, we continue to maintain cost discipline while investing in technology and clinical programs to further support medical margins and patient outcome improvements. as well as strengthen our position with payors and PCPs. All these actions are supported by our enhanced data and analytics capabilities that benefit our geography, practice selection, contracting and day-to-day operating visibility. Jeff will talk more about these important improvements. In closing and before I turn it over to Jeff, there are a few points I want to underscore. First, we see '25 as both a transition year in terms of membership and financial performance and an inflection year in terms of focused quality, clinical program and payor underwriting work to further position our platform and network as the scaled solution for physicians and health plans in full risk care for senior patients. Second, the scaled platform we have built across 615,000 senior patients, 2,200 PCPs, 30 markets and 12 states has yielded more favorable payor economic contract terms while delivering consistent outperformance relative to the MA and ACO quality and clinical cost benchmarks. Third, we believe the actions we took in '24 and our continued focus on reducing our exposure to things outside our control, pursuing measured growth due to current market dynamics, enhancing our core clinical and operational capabilities and maintaining cost discipline will further strengthen our network and support improved and sustainable performance for all stakeholders. And fourth and finally, while early, the advance rate notice is a positive signal that MA rates will improve for 2026 but it renews the call for rates that keep pace with increased costs in Medicare Advantage. With that, let me turn the call over to Jeff.
