Good afternoon, and thank you for joining us on Astronaut Health's First Quarter 2026 Earnings Call. Today, I'll begin with our first quarter results, then discuss how we have built and positioned Astronaut, anchored in our AI-enabled platform and longitudinal payer-agnostic care model and why that model is increasingly advantaged. I'll then provide updates on our four strategic pillars and our progress against each. And finally, I'll provide some color on the prospect integration, expansion market performance, and recent regulatory updates before turning the call over to John. Estrana delivered a strong start to 2026. We saw continued disciplined growth, well-controlled medical cost trend, meaningful operating leverage, and early performance from new full-risk contracts that continue to track in line with our underwriting expectations. More importantly, this quarter reinforces our broader thesis. As the healthcare environment becomes more complex, Advantage will accrue to organizations that can integrate care delivery, data, and financial accountability into a single operating system. Estrana has built that operating system, and we believe that Advantage is widening. In the first quarter, Strana delivered revenue of $965.1 million, up 56% year-over-year, and adjusted EBITDA of $66.3 million, up 82% year-over-year. Non-GAAP adjusted EPS was $0.74, up 76% year-over-year, and free cash flow was just over $64 million in the quarter. Deleveraging also continued to progress ahead of schedule, with net leverage declining to approximately 2.3 times on a pro forma trailing 12-month basis, and to 2.2 times based on the midpoint of our full-year guidance. As a reminder, when we announced the prospect transaction, we communicated a path to deleveraging below 2.5 turns of net leverage within 24 months. We have now achieved that milestone in just three quarters, and we anticipate ending the year at or below two turns of net leverage. We are pleased with the consistency of our performance and execution against our priorities in the first quarter, and our results increasingly reflect the advantages of the platform we have built and the way we are embedding AI across our platform. Our view is straightforward. AI can improve individual tasks, but the greatest value accrues to the orchestration layer, where data, workflows, clinical decisions, and financial accountability are integrated across the system. In healthcare, that means connecting how care is financed, coordinated, and delivered, and ultimately, improving outcomes for patients. We believe that requires deep architectural alignment. Unlike fragmented healthcare technology stacks assembled across multiple third-party vendors, our platform was designed internally as an integrated operating system. Because embedded orchestration across workflows, care delivery, and financial operations requires that. As a delegated payer-agnostic platform, we sit at the center of the healthcare ecosystem with a continuous, longitudinal view of each patient across plans, settings, and time. We are not tied to a single payer or a single line of business. We follow the patient throughout their healthcare journey. That creates two structural advantages. First, it creates long-term value. The continuity we build with our patients allows us to engage and manage care over extended periods of time, driving better clinical outcomes, more efficient resource allocation, and more predictable financial performance. Second, it creates a compounding data advantage. Our longitudinal view allows us to build a more complete and persistent understanding of each of our patients, which improves our ability to predict risk, intervene earlier, and coordinate care across settings. And on top of that foundation, we have built a proprietary data ontology and AI models that translate intelligence into action, embedding real-time insights, next best actions, and workflow orchestration directly into provider workflows and care management operations. Across our platform, our AI agents are increasingly embedded into operational and clinical workflows, helping manage authorizations, claims processing, care management, quality outreach, and next best actions in real time. Because these agents operate within our broader platform and data infrastructure, they act with longitudinal context across the patient journey rather than within isolated workflows. And these capabilities are embedded directly into the day-to-day workflows of our providers and care teams, driving measurable improvements at the point of care. Providers actively using our platform achieve a 24% higher gap closure rate and a 30% higher annual wellness visit completion rate. And those outcomes are increasingly powered by AI-enabled patient engagement at scale. including around 500,000 automated member interactions across voice and text each month, the equivalent of several hundred personnel worth of outreach capacity. We are seeing similar leverage operationally. For example, our AI claims agents have reduced provider payment cycle times to less than half that of manually processed claims. Taken together, these capabilities translate directly into improved clinical outcomes, more efficient operations, and ultimately more predictable financial performance. Importantly, because we operate the system our AI is improving, and because we maintain longitudinal relationships with patients across payers, the benefits compound over time within our platform. As more patients flow through our system, our models improve, our predictions sharpen, and our ability to allocate resources becomes more precise across the patient journey. That combination of longitudinal relationships, data continuity, and integrated workflows is what really enables us to translate AI into durable clinical and economic value. We continue to see those platform advantages translate into consistent clinical performance across the enterprise. In the quarter, medical cost trend slightly outperformed our full-year trend assumption of approximately 5.2%, with strong performance across both our core and legacy prospect populations as we continue integrating prospect onto the Estrana operating system. Our original Medicare populations in both ACO Reach and MSSP also performed well, reinforcing the scalability of our platform and the ability of our technology and clinical infrastructure to drive consistent outcomes across lines of business. We are also seeing that leverage reflected in our operating structure. In the first quarter, G&A as a percentage of revenue was 6.4%, a 70 basis point improvement year over year. As we continue embedding agentic workflows and intelligence across the platform, we expect additional operating leverage over time and believe that we will exit the year at levels below where we are today. Turning to membership, we ended the quarter serving approximately 1.55 million members in value-based care arrangements. On Medicaid and exchange, trends of the quarter remained generally in line with expectations, with puts and takes across the portfolio largely offsetting one another. Medicaid membership attrition tracked modestly below expectation, while acuity has remained favorable, reflecting less adverse selection than models, due in part to our longitudinal patient relationships. On the exchange, attrition tracked somewhat ahead of expectations during the quarter. And overall, we continue to manage these dynamics with a disciplined and appropriately conservative approach, and our broader assumptions and outlook for 2026 remain unchanged. On prudent risk progression, we delivered on the commitment we made in late 2025 to convert key contracts to full risk arrangements. At quarter end, approximately 80% of care partners' revenue and around 40% of own membership were in full risk arrangements. Importantly, new contracts that commenced this quarter are performing in line with our underwriting, reinforcing the discipline of our approach. Collectively, our results reflect continued execution across the four strategic pillars we have discussed consistently over the past several years. Disciplined growth, prudent risk progression, strong clinical and medical cost performance, and expanding operating leverage through our platform. Now, turning to prospect, integration remains on track and continues to validate the strategic rationale for the transaction. We have completed financial standardization, established full visibility into medical economics, and aligned clinical workflows under the Estrana care model. Gross provider retention remains above 99% for the quarter, and we continue to track towards the high end of our $12 to $15 million annual synergy target. In our expansion markets, Southern Nevada, which reached run rate profitability in 2025 with a 20% year-over-year improvement in MLR, continues to perform well. In Texas, the launch of our full-risk delegated model with a large payer partner on January 1st is progressing in line with expectations, and we expect our platform and operating model to drive of a similar maturation curve over time in Texas, as we've observed in our other markets. Finally, some quick comments on the regulatory environment. On the 2027 Medicare Advantage final rate notice, we believe there continue to be structural tailwinds for Estrada. Our model is not dependent on diagnosis sources that are being disallowed, and our historically conservative and counter-based approach to risk adjustment positions us well under the revised framework. More broadly, as regulatory changes continue to minimize risk adjustment as a source of alpha, we expect relative performance across the industry to be increasingly driven by underlying clinical execution and cost management. That is core to how we operate. To close, our first quarter results reinforce the structural advantages of the Estrana platform. We are growing with discipline, progressing risk responsibly, managing medical costs with consistency, and continuing to widen a durable technology and AI advantage that compounds with every patient we serve. With that, I'll turn the call over to Chan.

Thank you, Brandon, and good afternoon, everyone. Our first quarter financials reflect solid execution and a strong start to 2026, driven by the commencement of new full-risk contracts, continued contribution from prospect, and disciplined platform-wide performance. Total revenue for the first quarter was $965.1 million, up 56% versus the prior year period, driven by the full quarter contribution from prospect, commencement of full-risk contracts, and continued organic growth across our care partners segment. Adjusted EBITDA for the quarter was $66.3 million, up 82% versus the prior year period. Both revenue and adjusted EBITDA came in at the higher end of our guidance range, reflecting the durability of our model. Net income attributable to Estrana was $14.4 million, and adjusted EPS was $0.74 per share. Medical cost performance in the quarter was in line with expectations. Our 2026 plan assumes a blended cost trend of approximately 5.2%, and Q1 actuals across both legacy Estrana and legacy prospect were consistent or better than plan across all lines of business. G&A as a percentage of revenue was 6.4%, compared to 7.1% in the prior year first quarter. This 70 basis point improvement reflects continued operating leverage as we scale revenue and continue to embed AI capabilities across the enterprise. Free cash flow for the quarter was $64.1 million, due to strong operating performance and conversions to full risk. We continue to expect strong full-year free cash flow generation as new full-risk contracts ramp, working capital normalizes, and integration-related investments decline. We ended the quarter with $478.4 million of cash and $586.8 million of net debt. Net leverage on a pro forma basis was approximately 2.3 times, down from 2.6 times at year-end, reflecting strong free cash flow generation and continued EBITDA growth. We remain committed to meaningful deleveraging over the next 12 months through profitable growth, free cash flow generation, and disciplined debt reduction. We are reaffirming our full-year 2026 outlook. We continue to expect total revenue in the range of $3.8 billion to $4.1 billion, adjusted EBITDA between $250 million and $280 million, and free cash flow between $105 million and $132.5 million. We're pleased with our first quarter performance and continued execution, and remain disciplined in our approach to full-year guidance. Our outlook continues to assume conservative Medicaid membership trends and zero contribution from HCOF. We expect greater clarity on both items as the year progresses, and until then, we will continue to apply an appropriately conservative approach to full-year guidance. As a reminder, the midpoint of our 2026 guidance reflects our operating plan. The low end assumes a stacked downside case rather than a shift in underlying execution. On the headwind side, we have embedded expected declines in Medicaid and exchange enrollment, adverse selection, losses associated with new cohorts and expansion markets, conservative medical cost assumptions, and zero contribution from HCOF. On the tailwind side, we have modeled improved 2026 Medicare Advantage rates, continued realization of prospect synergies, ongoing maturization of full-risk cohorts, and operating efficiencies driven by automation and AI deployment. For the second quarter of 2026, we expect revenue between $965 million and $1 billion and adjusted EBITDA between $65 million and $70 million. Taken together, our first quarter results give us continued confidence in our ability to deliver against our 2026 framework. With that, operator, we're happy to take questions from the audience.

Thank you. If you would like to ask a question, please press star 1 on your telephone keypad. A confirmation tone will indicate your line is in the question queue. You may press star 2 if you would like to remove your question from the queue. And for participants using speaker equipment, it may be necessary to pick up your handset before pressing the star keys please limit to one question and one follow-up question our first question is from jack sliven with jeffries please

proceed hey guys thanks for taking the question um candidly crazy afternoon so a little trouble processing information maybe just to hit on what i think are like the three biggest things for everyone here. I heard the commentary on the trend better or in line with what you're expecting across all books. If I just think about enrollment and trend in Medicare Advantage on the HIC side and in Medicaid, can you just give me the rundown on sort of where that stuff's landing versus expectation and how to think about the progression there versus what you sort of already expressed

at the last quarter call. Thanks. Will the speakers please check and see if their line

is muted? Sorry, can you guys hear me? Yes. I apologize. Sorry, I know that that was a busy quarter. Jack, thank you for joining anyway. Happy to give an update per line of business on enrollment and trend. For starting off in Medicare, enrollment came in, as we had described before, mid-single-digit growth in eligibility. I'll start first with enrollment and then go to trend. On Medicaid, as I mentioned in my prepared remarks, enrollment or disenrollment tracks slightly ahead of the midpoint of our range. And so we're looking at probably on the high end of our range for disenrollment for the year. And then finally, for exchange, things came in better than expected in terms of disenrollments, as has been noted industry-wide. In terms of trend, we were able to come in at or above our full-year range for TREND, which is a blended 5.2% cost trend year-over-year. And so TREND has performed, you know, very well across all lines of business. Notably, TREND came in better in Medicaid as well relative to our expectations. So there was lower adverse selection so far throughout the year than we expected, even with the slightly higher disenrollment than expected. So as I mentioned in the prepared remarks, Medicaid and exchange kind of puts and takes there ended up balancing out and trend ended up performing better, you know, than expected really across all lines of business and for both core and legacy prospect populations.

okay got it super clear and super helpful um just one follow for me and the the balance sheet obviously now getting to a better position i know you called it out and then sort of a lot of where you had been messaging and things progressing nicely and and good free cash flow generation in the quarter i guess maybe just thinking about you know you had done some m&a nothing obviously on the scale of prospect beforehand but as you sort of get that leverage taking down and think about what you can do with excess free cash. We'd love to get your thoughts just on, you know, what you think the best use of cash is here, if there's ample talking opportunities, if the buyback is something you should look at. Just curious to sort of hear what you're thinking about there.

Yeah, of course. You know, overall, our approach to capital allocation, you know, I think is going to remain disciplined and consistent with the priorities we've previously communicated. You know, first and foremost, of course, our near-term focus is on deleveraging following the prospect transaction. And as I mentioned in the remarks, you know, we're very pleased with the pace of progress so far. As I mentioned, net leverage already declining to approximately 2.3 turns, you know, on a pro forma TTM basis. And that's far ahead of the timeline we originally communicated when we announced the transaction. And so when we think about capital deployment, I think our highest priority continues to be investing organically into the platform, including our technology infrastructure, AI capabilities, clinical operations, and expansion markets. and we see strong returns and a meaningful runway ahead in those efforts. On M&A, though, it's really a question about capital allocation efficiency. I think we believe we already have the core capabilities required to operate a fully integrated, AI-enabled healthcare operating system internally. So the question is less about acquiring technology capabilities and more about determining the most capital-efficient way to expand membership, provider relationships, and market density over time. So it's going to be a bit of a buy versus build question in terms of M&A. That being said, we continue to believe the platform is extremely well positioned to integrate and scale M&A acquisitions over time. Because we've built that proprietary operating platform, I think we've proven that we're able to operationalize acquired assets very efficiently and very consistently across the platform. And we've demonstrated that capability, as you noted, with prospect, but also with things like collaborative health systems, CFC, and more in the past. So, it's going to be an important opportunity to continue growing the platform, but we're going to remain disciplined and highly selective in the approach. And finally, on share repo, you know, we did continue to do share repurchases in Q1 as we have in Q4 of last year, and we'll continue to evaluate, you know, that capital allocation strategy dynamically based on where we believe the risk-adjusted return for repo will be and where we think we can create kind of long-term shareholder value. So, given the strong cash generation so far and that the integration is on track and ahead of schedule, you know, we're pleased with where we are, and we think we have a lot of flexibility over time as we continue growing the platform.

Got it. Appreciate all the color and nice work on the quarter, guys.

Thanks.

Our next question is from Ryan Daniels with William Blair. Please proceed.

Yeah, guys, thanks for taking the question. Congrats on the strong start to the year. Brandon, I thought you gave a great overview of the Estrana operating platform and the advantages it gives you both on care and operating efficiencies. So I'm curious, how much more leverage do you have there to drive maybe G&A efficiencies and what type of new programs are you launching? And then as a follow-up there, I'd love to learn more about how you plan to commercialize that in the market, as other vendors kind of struggle sometimes to manage cares effectively via your care enablement partner offering.

Hey, Ryan. Thanks for the question. You know, I think there's a lot of – I described some of the examples of how we're using, you know, technology so far. It's really deeply integrated into the system, and it helps that we have a fully delegated capitated model where we do act as a single payer, and we have the visibility across authorizations, claims, care management, and the entire ecosystem. You know, so far, as I mentioned, we've really been using a lot of AI in terms of our risk stratification models or next best action models, you know, creating a suite of agents on both the payer-facing and provider-facing side, on the payer side, for example, on, you know, claims adjudication and prior authorization, on the provider and patient side in terms of engagement, you know, through voice and text, as well as clinical documentation and gap closure. I think some opportunities remain in further expanding our agentic care management workflows, something we've developed over the last half year or so that is already in use but certainly can lead to further efficiencies on both the OPEX and hopefully over time on the cost of care line as well. We're also looking at, of course, continuing to finish off the integration of prospect onto the stronger operating system, which can drive further operating leverage as well as over the medium-term medical cost leverage and continue to expand our clinical decision support capabilities embedded directly into the provider workflow as part of the Estrana operating platform. So I think there are going to be continued opportunities. And like I mentioned in the prepared marks, already reduced G&A as a percentage of revenue, 70 basis points year over year, and expect to exit the year even lower than where we came in around, around, sorry, lower than where we came in, 6.4% in Q1. On the second question, in terms of commercializing this in the market, I think perhaps an underappreciated part of our story is that there is a segment that we report in which we do commercialize some of these tools to the market in our care enablement segment. That segment continues to grow rapidly, has a strong gross margin and EBITDA margin profile. and just in this quarter we added a new client which we had disclosed kind of on a previous earnings report to that client base in the care enablement business. So we continue to grow that business rapidly and we think there is potential to not only improve groups and clients in that business but also one day potentially as we did with the community family care acquisition to look for deeper ways the partner and get them perhaps into our care partner's business.

Great. Perfect color. And then one quick follow-up. This is more housekeeping, but with the Quality Assurance Fund, I know that's not included in your guidance. Has there been any update there or any thoughts on when we might get timing on that to see if there could be potential contribution to this fiscal year for you guys? Thanks. Thanks, Ryan. Yeah, I think that's

unfortunately going to have to wait until later in the year. We don't have an exact date in mind, but probably in the third or fourth quarters. So, again, out of conservatism, we've left that contribution out of the guidance for 2026, but we'll look forward to hearing more and updating the street when that happens.

Okay, fair enough. Thanks again, guys. Nice work on the quarter.

Our next question is from Jalanda Singh with True Securities. Please proceed.

Thank you. Thanks for taking my questions, and congrats on a strong quarter. Brandon, I know you have been cautiously optimistic around your 2027 EBITDA target of $350 million, and you've said that there's still a path to get there. But in recent few months, there have been some positive developments around 2027 CMS MA rule. You just said that Medicaid and HICS have been trending better, at least in line to better expectations, and then you're also driving AI-driven efficiencies. Are you feeling better about the target now versus three months back? Or at least you're willing to say that in consensus, which is around $314 million, seems to be at least in reasonable range. It's trying to understand how your views about 2027 might have shifted in the last couple of months or three months.

Hey, Jalandra, thank you for the question. When we originally provided that 2027 adjusted EBITDA framework, this was back in 2024. Of course, we're in a meaningfully different regulatory and industry environment than the one we're operating in today. But that being said, I think the more important point, the more salient point, is the continued strength and adaptability of the astronaut platform over all environments. Our model was designed to operate across cycles, as I've mentioned many times before. And we believe the consistency of our performance over, you know, really decades of performance, but certainly even in the last five or six years, certainly reflects that. As an example, from 2019 through guidance for 2026, we've grown revenue at approximately a 32% CAGR and adjusted EBITDA at a 25% CAGR, while continuing to generate, you know, operating leverage and free cash flow along the way as we grow very, very rapidly. And against that context, you know, looking forward into 27 and beyond, we think that the business has continued to be positioned to grow organically at a mid to high teens rate while continuing to deliver, you know, on free cash flow as well. We see meaningful opportunities, of course, to accelerate that growth past the mid to high teens growth rate through a disciplined and selective M&A potentially over the long term, particularly given the scalability of what we've built. But even without M&A, you know, we still think that's a mid to high teens organic grower. And so that being said, you know, I think the key takeaway here is, you know, really the operating model and its durability across all regulatory and economic cycles, our ability to continue compounding growth as we have, you know, 25%, you know, both organically and inorganically over the last six, seven year period, and our continued expectation that off of the 2026 number, that mid- to high-teens CAGR on the EBITDA line is firmly within reach over the short- to medium-term future.

Makes sense. And then my follow-up on the AI investments, you talked, I think in the presentation you said that your GNA has been benefiting from AI-enabled tools. And is the message that all of the 70 basis point year over improvement was driven by these AI tools, which will imply like $7 million benefit in the quarter alone. I just want to confirm that. And then as we think about the broadly AI investment strategy, how will these investments split between focus on administrative aspect of the business where savings might directly fall to bottom line right now versus investing in clinical workflow so that these drive more savings down the road? Just help us understand how do you allocate your AI investment strategy and dollars?

Yeah, of course. You know, I think it's a little hard to say exactly how much of the 70 bps, you know, is driven directly by AI. You know, certainly AI is being infused across the board. So, you know, I would say a meaningful part of that without quantifying, you know, is driven by AI and its ability to help us scale the business without, you know, without increasing G&A cost associated with that rapid revenue growth. in terms of the split between, you know, more administrative functions and, you know, maybe clinical or coordination, navigation-related functions that could potentially have an impact on medical costs, you know, in the short and medium-term future. You know, I think it certainly started off on the payer side and on the G&A side. We built agents around claims, around authorizations, around eligibility. And I think over the last probably year or two, you know, we've been building a proprietary suite of, you know, more clinical facing tools such as risk stratification, care management, workflow orchestration, and genification that I think will lead to MLR improvements over time. You can see that a little bit as we may be getting a little off topic here, but you can see that a little bit with how Prospect has performed as we continue to onboard them onto the Strana operating system. You know, Prospect prior to the acquisition had medical cost trend running, you know, six, six and a half percent or so. We modeled around 50 basis points of improvement in 2026 versus that number, and we're outperforming that by a bit here, even in Q1, even though we've already improved by that 50 basis point margin. So I think you'll really start to see even more MLR improvement in the medium term, but I would say the improvement's largely skewed towards GNA at this point in time.

Got it.

Our next question is from Craig Jones with Bank of America. Please proceed.

So, Brandon, I want to follow up on your comments around your encounter-based risk adjustment model in MA. So it sounds like CMS, you know, keeps mentioning, like, leveling the planning field in MA and really wants to rewrite, you know, the current MA risk adjustment model. So if you were in the room with them, you know, redoing the risk adjustment model, you know, what would you recommend changing? And then how do you think the potential changes they end up making, you know, potentially going to this encounter-based model would help Estrada? And then, you know, do you think you could see something along these lines as soon as the 2028 technical notices fall?

Thanks for the question. Yeah, I think the future of risk adjustment is really interesting. As you can see in the ACO lead preliminary model details, there is the phasing in of an AI-inferred risk score, which would depend not necessarily on an organization's ability to document and submit codes, but rather trying to use AI to infer the true acuity of the member and reimbursing appropriately based on that kind of quote-unquote gold standard kind of determination of a member's risk. Again, I think ultimately, because we've been conservative on risk adjustment, because we're, you know, we see members over a longitudinal period of time, and we try to be very appropriate in terms of capturing the clinical complexity of the population, we think that either way, we're well structured, you know, we're well positioned, you know, for that future. We think that because we haven't relied on documentation or coding optimization to generate savings and value for the healthcare system in the past, it may even be beneficial for us, for example, to have a true determination of what a patient's risk is via AI that the government or CMS is going to determine rather than everyone playing a game to try to improve their risk scores over time on a relative basis. So I think really, regardless of how all of that shakes out, we think we're structurally well-positioned for the long term. That being said, if I had my way, I do think that risk adjustment as a source of alpha is not really, I think, in the benefit of the healthcare ecosystem in the long term and for the Medicare trust fund in the long term. So I would recommend, without knowing more, that some of these approaches that are being suggested, like AI-inferred risk models, seem very appropriate and seem like a much more efficient way to standardize what risk determination looks like across the American population.

Okay, great. It's good to hear. Thank you.

Our next question is from Michael Howe with Baird. Please proceed.

Thank you. So when it comes to AI, clearly everyone's talking about a discerning season, all the large national payers, providers. But the thing is, most of them have pretty legacy, old infrastructure, fragmented data, as you said yourself. So when I think about Estrana versus, I guess, almost all of your peers, it's the fact that you built an AI-native tech platform many years ago and the fact that you yourself are spearheading, forcing AI adoption across basically every facet of your company. I think that's still widely underappreciated. So I was wondering if you could talk more about this specifically, the structural differences between you, Estrana, versus your peers when it comes to unlocking the power of AI? In other words, what still has to happen, what still has to be done by our peers to get there versus what can already start to happen at Ashrana?

Yeah, thanks so much for the comments, Michael. I think broadly that's right. I think our thesis has always been building internally, and I think that thesis is being rewarded in an era where it is easier than ever and faster than ever to build internally because of the advent of generative AI and its use in coding. And I think as long as you have the integrated data infrastructure to support that, the ontologies on top of that, the definitions, the concepts, and the relationships between those concepts so that the AI understands how to operate on each of these concepts and how they relate to each other and how they ultimately translate into actionable insights, I think that's hard to replicate, right? I think if you're operating a system where you've acquired a bunch of stuff and you haven't integrated them into a unified data layer with a unified set of concepts and vocabulary on top of that, on top of which the AI and the agents can operate, you're going to find it very difficult to kind of build the fifth floor of the building without having the structural supports, you know, the ground floor and the lobby built out. And I think that's a lot of what our peers are doing, perhaps, without getting too much into what our peers are doing. I think there's a rush to chase the kind of the sexiest parts of AI to build the top floor, the penthouse unit, without having the foundational approach, without having the pickaxes, the knowledge about how to dig the hole in the foundation into the ground to build that in an effective manner. I think we've spent a lot of time, myself personally, given my engineering background, to build out that foundation, and now we think that's going to unlock our business in terms of rapidly adopting AI across the enterprise and embedding it deeply into each and every workflow, both operationally, clinically, and on the quality of care side. So we're really excited about where we can take this platform. We're already seeing the GNA improvements. We're starting to see some of the trend improvements as we continue to integrate new businesses onto the platform. And we're seeing great success as well in terms of our care-enabled business, selling the tools and the integrated workflow that we've built to other provider groups and helping them succeed also in an accountable care relationship.

Great. Thank you so much. So, next question, on the final MA rate notice, so I'm getting roughly, like, 4% net rate increase for Estrona if I exclude on-linked chart reviews, and when I think about Estrona's margin expansion, just how sensitive it is to the rate environment, I know your cost trends are running, I think, 4% to 5% roughly for MA, so at face value, right, that would imply rates are basically, they match up, but if I start at 4%, add maybe 1% to 2% coding, maybe another 1% to 2% of help from plans, you know, benefit design, pricing. Then we're getting into a different sort of ballpark of 6% to 9% rate, versus trend of 4% to 5%, you know, up to 400 basis points in margin expansion. So it feels quite considerable, and that's not even including, right, your regular cohort maturation dynamics, any other trend vendors of G&A. So at a high level, am I missing any major components? Is this even the right way to start thinking about 2027?

Yeah, Mike, as always, your math is great. So I would broadly agree with your comments. You know, I think the final rate notice was what's constructive, you know, overall, and the, you know, the overall top line kind of effective growth rate, 5.33%, you know, does more appropriately reflect underlying medical cost trend. And as you mentioned, the disallowed diagnoses or the diagnoses, sorry, are expected to be immaterial for Estrona, given our historically conservative and encounter-based approach to risk adjustment. So as you had noted correctly, the average change for us might be the 2.48% plus the 1.53% or approximately 4% in aggregate. And as we think about 27 more broadly in our models, at our current RAF levels, we probably expect to maintain MA margins consistent with 2026 with that 4% kind of average rate book increase. Beyond that, we continue to see tailwinds and opportunity for more accurately capturing the complexity of our populations in risk adjustment. And there's potential tailwinds above and beyond the 4% from those sources.

Great.

Our next question is from David Larson with BTIG. Please proceed.

Hey, congratulations on the great quarter. Can you talk a bit about your margins for, like, I guess, full cap books of business that would include inpatient? inpatient, and can you remind me what regions or how many members are full cap, including a pharmacy, doc, inpatient? Thanks very much.

Thanks for the question, Dave. Thanks for tuning in. Our fully capitated arrangements start off in lower kind of EBITDA margin arrangements as we transition them from full risk because, as we talked about before, you get the kind of increase in percentage of premium without yet necessarily flowing through the decrease in inpatient utilization as we take on additional portions of the risk dollar. Over time, the maturation of the full-risk cohorts, as we've seen over the past years as we've moved members, you know, cohort at a time into full-risk arrangements, and as we continue to do that as we did in Q1 of this year, you see that margin profile mature and ultimately get to hopefully a similar point as the kind of partial risk members as well. So I think that's what we expect as we continue to move members selectively and prudently into full risk arrangements. We underwrite kind of this margin maturation cycle. We've seen that happen now over several years and each of those has matured as expected. And so we can kind of space out our membership moving into full risk as appropriate. I do want to mention that, you know, almost all of our full risk arrangements do not include Part D, as in dog, you know, risk. So, you know, there are a handful that do, and most of them do not. In terms of the geographies where we are full risk, you know, it really varies. Most of our membership, you know, 80% of the revenue approximately comes from California. So I would say still that California does have a large percentage, you know, a majority of the full risk members. However, we have moved over 14,000 Medicare Advantage members into a full-risk delegated construct arrangement with a payer partner, for example, in Texas in the first quarter of this year. And we also have full-risk delegated contracts in Nevada. And, of course, the ACO REACH business is in some aspects a full-risk business also. So, you know, we're really in the business of properly underwriting and then appropriately and proactively reducing the cost of care for our populations and then making sure that our financial contractual arrangements are conducive to us, you know, capturing some of the value that we're generating for our patients and for our communities over time.

And then for Prospect, I think you may have mentioned this earlier, is it still 80 million of EBITDA? Is that on track?

Yeah, that's right, Dave. Prospect was on track for around $80 million of adjusted EBITDA on an annualized basis. And at this point in time, it is currently tracking a bit ahead of those expectations.

And then just one quick one. It looks like your stock has been doing really well over the past couple of months. I guess, what do you attribute that to just at a high level? Thanks.

I mean, we're always happy to see that as it's our job to continue generating, you know, shareholder value, of course. You know, I think, I hope, you know, it's a continued recognition of our leadership and our consistency and stability of our model, the differentiation of our technology platform, you know, the 35% revenue CAGR, the, you know, the 25% adjusted EBITDA CAGR that I mentioned, you know, which I think is fairly unheard of in healthcare services over a very long period of time over seven years. And ultimately, of course, it definitely helps that there have been regulatory tailwinds, including the adjustment, the more appropriate, in our view, 2027 Medicare Advantage final rate notice. So I think overall, a lot of positive kind of macro tailwinds lining up, and hopefully an increased recognition of the unique platform that we've built that has really generated free cash flow, profitability, and now rapid growth for over three decades.

The best health care is when you don't actually have to see your doctor, and that's the model that you guys have created.

So, nice quarter, and thanks.

Thanks so much, Dave.

Our next question is from Ryan Langtham with TD Catwin. Please proceed.

Hi, good afternoon. This is Christian Borgmeyer on for Ryan. So, looking at the second quarter guidance and EBITDA margin, how should we think about puts and takes within the cost of service revenue and GNA lines? For example, any seasonal considerations within medical utilization in particular that are different this year or on the GNA side, any sequential savings from AI or prospect synergies embedded in that? Thanks.

Hey, how are you? In terms of our 2026 guide, probably the best way to think about this is in the first half of the year, we're probably going to see a little over 50% of profitability coming in, consistent with what's happened in historical years. As you think about puts and takes, the puts and takes, as we mentioned, it's around HCOF, it's around opportunities with MA and ACO, as well as watching in terms of what's going to happen around the Medicaid membership trend.

And then maybe to answer the other part of your question, we didn't see any abnormal utilization necessarily in Q1. I know there's been talk about weather and the flu season and whether that was heavier or lighter. You know, I don't think, you know, things came in pretty operationally clean is how I characterized the quarter and tracked pretty consistently both on the inpatient and outpatient side with the broader medical cost trends that we reported across the business, even down, drilling down into each line of business, you know, as I started off the Q&A session with. So we felt pretty comfortable this quarter, and we're maintaining guidance primarily because we want to take a disciplined and, you know, and conservative approach early in the year here.

Got it. Thanks. I actually had a quick balance sheet question, actually. I see the accounts receivable balance and the medical liabilities balance are each up like $90 to $100 million sequentially. Anything to call out there related to any one item or program in particular, or is that the full-risk conversions contributing to that?

Yeah, that's the full-risk conversions that you're seeing in Q1.

Got it. Thank you.

Thanks.

Our next question is from Gene Mannheimer with Freedom Capital Markets. Please proceed.

Thanks for taking the question, and congrats on a good start to 2026. so coming in or tracking to the high end of cost synergies with prospect can you discuss potential revenue synergies there and when when you you may start to see that realized and my follow-up would be you know on the mlr trends at or better than the 5.2 percent or so that you called out did you or can you break that out across the legacy astrana and the prospect

book. Thanks. Hey, Gene. Thanks for calling in. Sure thing. So on the revenue synergies, you know, we haven't – those are not included in the $12 to $15 million synergy range. So we haven't – you know, we haven't quantified that yet. But we do expect over time that our partners and our providers and ultimately our members will see the value of our denser network and our ability to drive access to care, high quality care, you know, in a faster way because of the larger network that we now have. So over time, we do think that that value will be realized by the platform, but we haven't yet quantified necessarily what that looks like. On the trend item, I would say that, you know, as I mentioned before, Prospect came in, you know, six to six and a half, you know, 6.2, 6.3% trend prior to the acquisition. And we are underwriting a 50 basis point improvement in that trend year over year. Our overall trend for the year is around 5.2% on a consolidated basis. And I would say that, you know, both core astronaut as well as legacy prospect businesses perform better than expected here in Q1. Again, it's still early on in the year. We don't have perfect visibility, claims visibility yet, for example, on March. So we wanted to be conservative, but things are tracking well here to start the first quarter.

Terrific. Thanks. Our next question is from Matthew Gilmer with KeyBank Capital Markets.

Please proceed. Hey, good afternoon. Thanks for the question. I wanted to follow up on the full risk contract transition discussion. I think this quarter you had 40% of members in full risk. I think last quarter you set an expectation of 36 members in full risk as of the first quarter, So maybe a little bit ahead of schedule.

I wanted to see if I had those numbers right and then just get an update in terms of how you're thinking about the pacing of members moving into full risk over the course of the year.

Hey, thanks for the question. Yeah, I think that's approximately right. You know, around 40% of our members are in full risk arrangements, and that translates into around 80% of our care partners' revenue, you know, being or coming from full risk arrangements. And, of course, that's because the percentage of premium that we receive in the full-risk arrangements per member, you know, is obviously higher than the partial-risk arrangements. So I think you're continuing to see that the percentage of both membership and revenue continue to grow. In Q1, this took a step up because of the full-risk contracts that we had started in the first quarter, as we had guided to, you know, late last year. And all of those have now been completed. And so that's what's led to the spike here in Q1. On a go-forward basis, I think in our supplemental presentation deck, we did note that we do expect continued growth in the percentage of for-risk members, and we'll be phasing that in over time kind of on a regular course basis.

Okay. And then as a follow-up, we've been particularly interested in your ability to bring this delegated model into new markets. And so the news out of Texas that you've updated this on has certainly been encouraging. I did want to take your temperature in terms of expanding, you know, a delegated model either into new markets or even just new states or even just new markets within states like Texas, which, you know, many of those places traditionally haven't had fully delegated models.

Yeah, it's a great point. And you're absolutely right. A lot of parts of the country have not necessarily operated in a, you know, don't even mention delegated model. They haven't even operated really in a value-based care setting in a broad way. And so we recognize the challenges of kind of going zero to one in a very short period of time. And I think that's why we've been really working on a gradated kind of approach to helping providers and payers along as we continue to take the Estrana delegated model outside of California, outside of Nevada, outside of Texas, and through the rest of the country. You know, what that looks like really is, you know, first entering into partial risk arrangements, ensuring that the data feeds that we need are on the ground and ready to go, ensuring that our relationship with our downstream providers, you know, primary care specialists and even hospitals, you know, are strong, ensuring that our technology platform is integrated directly into the workflow of those providers, and ensuring that kind of our care management orchestration is in place. and kind of allowing the economic contractual relationships to kind of follow behind in the wake of the operational changes that we're making in terms of how health care is delivered in these new states and or geographies. So it is a gradated kind of stepwise approach to getting folks into the delegated model. We think that it ultimately will win out because, frankly, at the end of the day, it's just a more efficient model. You know, it's a more valuable model to the health care system and a more efficient one for both payers and kind of the overall system. So we think that logic will take the day here and, you know, the economics of it will take the day. But we do recognize that change management takes time and we're prepared to and have, you know, engaged, you know, in Florida – I mean, sorry, in Texas and Nevada, for example, on that path, you know, forward, step by step. Great. Thanks a lot.

Our final question is from Andrew Mock with Barclays. Please proceed.

Thanks. This is Thomas Wall, Sean, for Andrew. You shared that acuity in the Medicaid population remained favorable, in part due to your longitudinal patient relationships. Can you help us understand how those patient relationships mitigated the acuity impact in practice? And are there any other factors on the mix of members disenrolling or otherwise that mitigated the adverse selection?

Yeah, definitely. I think what I was alluding to, to put it more clearly, is that, you know, the patients that tend to be Astrana members, which, you know, and the patient attribution mechanism is the choice, you know, the selection of a primary care provider who is an Astrana primary care provider, the members that tend to be attributed to us tend to not be the members who have low to no utilization because, you know, they are almost making an active choice to be an astronaut member and to be engaged in our care model and to be engaged in the longitudinal nature, you know, of the care model that we have, you know, with our patients as we follow them, for example, across line of business. You know, I'd mentioned before the example of during COVID, you know, members who lost their jobs and had to switch from a commercial line of business, a commercial insurer, to potentially something on the exchanges or something on Medicaid, for example, could continue to be in the astronaut ecosystem, continue to have the same care management, continue to see their same PCP and same specialist network. Those are the benefits, I think, of being in this genre network, and that tends to insulate us, or we think, you know, partly insulate us from the level of adverse selection we expected from the disenrollment of members and kind of potentially their lower MLR. That didn't end up playing out the way that, or to the degree that we thought, you know, know, it would, and that's what's led to some of the improved acuity in the Medicaid population.

Thanks. And following up on ACA attrition, tracking better than expectations, similar to trends across the industry, could you share the actual disenrollment you experienced there? And at what point in the year would you expect to have enough visibility to make an informed revision to the full-year membership expectation? Yeah, I think at the beginning of the year,

Embedded in our guidance, we thought it would be a 30% to 40% disenrollment number in exchange throughout the year. And I think we had quantified that at a kind of mid-single-digit EBITDA impact, headwind, of course. What we're seeing so far this year is not quite the 30% to 40%, really closer to high single-digit attrition in the ACA population. It still is early. You know, we're still in May here, and there could be further disenrollments after the 90-day grace period. But, you know, across the industry, as we think about projections from actuarial firms and what others have been saying, as well as our own experience, we're now projecting a decline of, you know, call it 20% to 30% instead of 30% to 40% internally, at least. Again, we haven't reflected that in the guidance yet out of conservatism, but, you know, that's kind of the quantum of the numbers we're talking about.

Great. Thank you.

There are no further questions at this time. I would like to turn the conference back over to management for closing remarks.
