Good afternoon, and thank you all for joining us today. We are pleased to report a strong start to the year with first quarter results that reflect the continued momentum behind our strategy to build the nation's leading patient-centered healthcare platform. At Astrana, our progress is rooted in disciplined execution across four strategic pillars: First, we are sustainably growing our membership to expand access to high-quality care for more Americans. Second, we are strengthening alignment between patient outcomes and financial performance through thoughtful risk progression in our value-based arrangements. Third, we are improving care quality and patient outcomes while managing costs effectively. And fourth, we are driving operational excellence through our proprietary care enablement platform, which supports clinical teams, enhances workflow efficiency, and scales our impact. What continues to differentiate Astrana and what really drives our consistent performance across all market and policy environments is a combination of our physician-led clinical capabilities and our delegated model, which enables us to act as a single payer for our physicians. Our care delivery infrastructure integrates high-performing provider networks with direct care delivery capabilities in our clinics and with our care management teams, enabling us to manage care more proactively and more consistently. In parallel, our delegated payer-agnostic model allows us to build longitudinal patient relationships and gives us real-time visibility into utilization and claims, allowing for earlier interventions, more coordinated care over time rather than episodic interventions, and ultimately, better outcomes. When paired with our proprietary technology platform, we're able to address regional differences in a consistent way, identify anomalies, and act on insights in real-time. The result is greater stability and predictability in both medical cost trend and MLR performance regardless of geography, policy environment, or economic cycle. With that, I'll share some financial highlights from the first quarter. In the quarter, Astrana generated total revenue of $620.4 million, a 53% increase compared to the prior year period, and delivered adjusted EBITDA of $36.4 million. Revenue growth was driven by our Care Partners segment, which grew 57% year over year to $600 million. CHS contributed $95 million in the quarter, which was in line with our expectations. Adjusted EBITDA in the first quarter reflected our continued success in growing membership and value-based arrangements while managing cost trends effectively. Margins were moderated by planned ongoing investments in growth integration technology, as well as by revenue growth in areas with lower near-term margin profiles, such as the CHS acquisition and newly converted full-risk members, which was consistent with expectations. We expect this to improve in 2026 as previously guided as CHS moves towards breakeven this year and as our full-risk cohorts further mature. Medical cost trend in the quarter was in line with expectations in the mid-single digits, blended across all lines of business, with Medicaid trend above, and Medicare and commercial trend below, that blended average. Diving a little deeper here, despite a challenging flu season, which drove higher than normal ER and lab utilization, we are pleased to be on track with our full-year trend and profitability guidance. Turning to growth, our Care Partners segment continues to expand, reaching 910,000 members as of Q1 2025. We're also making disciplined progress in transitioning our membership into more strategically aligned full-risk arrangements. As of this quarter, approximately 38% of our members are now in full-risk contracts, up from 5.5% a year ago, and those members now account for 75% of our capitated revenue. Turning to our emerging markets, Nevada and Texas, we are seeing encouraging progress in both growth and operational execution in those markets. In Nevada, we achieved breakeven in both our risk-bearing network and our AstranaCare clinics during Q1, right on track with expectations. Membership in our risk-bearing network grew 40%, and clinic visit volume increased by 35% year over year, reflecting strong momentum in Nevada. And in Texas, we continue to transform the market to align with our single-payer delegated model over time, and we remain on track with reaching profitability in late 2025. These results reinforce the portability and scalability of the Astrana model, and we're pleased to see performance in these markets tracking in line with our strategic plan. Now turning to acquisitions. In 2024, our focus was on expanding our footprint and deepening our presence in key communities across the country. In 2025, our priority shifts to executing on that growth to unlock greater value across the platform. Starting with CHS, integration onto the Astrana platform for CHS is now complete. As expected, we've identified and executed on over $10 million in G&A efficiencies as CHS has onboarded to our proprietary technology platform. CHS's Q1 performance was in line with expectations, and as we continue to implement our care model and scale it, we anticipate CHS will reach breakeven profitability in 2025 and achieve profitability in 2026. We're also making measured progress in expanding our delegated activities in 2026 and beyond. As for our planned acquisition of Prospect Health, we remain highly confident in the opportunity ahead. The transaction will significantly expand our provider network in Southern California and will position us to serve approximately 1.7 million members in value-based arrangements. We continue to expect Prospect to contribute around $81 million in adjusted EBITDA and to deliver between $12 million to $15 million in synergies. And we look forward to closing on the acquisition this summer. As we integrate and scale these acquisitions, it's equally important that we continue strengthening the foundation of our organization. To that end, we've made several exciting additions to our leadership team this quarter. Georgie Sam has joined us as Chief Data and Analytics Officer to lead our enterprise-wide data analytics and AI strategy. Glenn Sebaca has come on board as Chief Accounting Officer, bringing deep experience to support continued financial discipline and scalability. And we're excited to have Rita Pugh step up into the role of Chief People Officer, helping us further invest in the talent and culture that drives Astrana forward. Now, I'd like to touch on several recent industry-wide developments. Starting with Medicare Advantage rates, we're encouraged by the 2026 Medicare Advantage rate notice, which we believe signals continued federal support for both the MA program and value-based care more broadly. The final rates reinforce a stable reimbursement outlook and should serve as a tailwind for Astrana's current business, and even more so for the pro forma business once the Prospect acquisition is complete, given the combined scale of the pro forma platform. Turning to California's Proposition 35, this was not a headwind for Astrana in Q1. While we are still working through the broader implications of the legislation with our plan and provider partners, our current view is that the net impact will be neutral to EBITDA once resolved. With regards to V-28, we have not seen a negative impact on our business. We have always taken a principled approach to value-based care, finding success by driving better patient outcomes and higher quality of care, not by exploiting reimbursement mechanics. We believe that this is the only way to build a durable company and to deliver on a differentiated care experience and improved outcomes for our patients. Similarly, our exposure to Part D risk remains de minimis, with less than 2% of our members with any exposure. That is entirely by design. We have always remained disciplined about taking on risk where we believe we can have a meaningful impact. We have avoided exposure where that control is limited. To close my prepared remarks, we believe that our ability to grow rapidly while delivering consistent profitable results is a direct outcome of our proven care model, disciplined execution, and proprietary AI-enabled technology infrastructure built to scale. We are proud to continue demonstrating that value-based care can be both scalable and effective, driving strong performance while improving patient outcomes. With that, I will now hand it over to Chan to discuss our financials in more detail.
