Thanks, John. For the year ending December 2023, our health plan membership of 119,200, increased 21% year-over-year. This exceeded our expectation of 17% membership growth at the midpoint of our initial guidance, thanks to the strong momentum of our sales and retention efforts as we headed into AEP. Our total revenue in 2023 grew 27% to $1.82 billion. Meanwhile, our adjusted gross profit of $209 million reflected an MBR of 88.5% for the full year and an MBR of 87.6%, excluding ACO REACH. Taken together, we are pleased to have balanced strong MBR results in our core business while delivering over 20% membership growth. We also made significant progress towards our operating leverage goals in 2023. SG&A for the year on a GAAP basis was $307 million. Our adjusted SG&A which primarily excludes equity-based compensation expense was $244 million. Adjusted SG&A as a percentage of revenue, excluding ACO REACH, was 14.4%, an improvement of 1.6% from the prior year result of 15.9%. We anticipate that this significant improvement will continue into 2024 as we benefited from our membership growth and several of our shared services productivity and scaling initiatives. Lastly, our adjusted EBITDA was negative $35 million. As previously indicated in our 8-K, our adjusted EBITDA result reflects decisions to increase discretionary investments in sales and marketing during the back half of AEP, given the significant growth opportunity presented to us. In support of this growth, we also accelerated new hires and clinical investments in December to assist with the onboarding of new membership. We are pleased that these minimal incremental investments successfully positioned us to achieve the 2025 year-end consensus membership a full year early. Subsequent to the release of our January 8-K, we saw $2 million of adverse development in our ACO REACH line of business related to fourth quarter days of service. As I will share more on momentarily, we have since executed the strategy to eliminate any downside exposure from our ACO REACH book of business in 2024. Moving to the balance sheet, our capital position remained strong as we ended the year with $319 million in cash and short-term investments. The sequential step down in cash compared to the third quarter included the previously discussed timing impact of an early payment from CMS of approximately $146 million in Q3. Turning to our guidance. For the first quarter, we expect health plan membership to be between 157,000 and 159,000 members, revenue to be in the range of $590 million and $600 million, adjusted gross profit to be between $52 million and $58 million and adjusted EBITDA to be in the range of a loss of $13 million to a loss of $19 million. For full year 2024, we expect health plan membership to be between 162,000 and 164,000 members, revenue to be in the range of $2.38 billion and $2.41 billion, adjusted gross profit to be between $275 million and $310 million and adjusted EBITDA to be in the range of a loss of $15 million to positive $15 million. Based on early Q1 trends, we feel confident in our ability to achieve our full year membership and revenue outlook. Our relative product value proposition, Stars differentiation and brand recognition continue to resonate in the market post AEP. We also continue to see improvements in retention that reinforce our full year membership target. Moving down the P&L, the following factors support our full year 2024 adjusted gross profit outlook. First, our Star ratings are stable year-over-year for 2024 payment. Second, as John mentioned earlier, the bid value of our added benefits remain roughly unchanged in 2024, increasing just 0.7% year-over-year. Third, the RAF we received for our new members is in line with our bid expectations. And lastly, our recent utilization experience continued to be consistent with our expectations. Fourth quarter inpatient admissions per thousand ran 7% better year-over-year, a trend which persisted into January. Diving deeper into our utilization experience, I'll spend a few moments on a few topical items. Flu and RSV inpatient utilization. Utilization trends for the full year and fourth quarter 2023 showed year-over-year declines. Flu and RSV are captured within our all-in 156 admissions per thousand for full year 2023. This category of utilization continues to be a primary area of differentiation, given the strength of our clinical model to prevent avoidable admissions and readmissions. Outpatient utilization. As we previously noted, our outpatient costs in 2023 ran within a few dollars PMPM relative to 2022. Additionally, our early 2024 preauthorization data which is a strong leading indicator of our outpatient volume continues to be in line with our prior year experience. Inpatient unit costs. We expect the impact of the Two-Midnight Rule to be immaterial. The majority of our hospital contracts in California which comprises 94% of our members already incorporate a de facto Two-Midnight Rule, while we foresee modest impact to our ex-California markets. However, we are incorporating higher than the national average inpatient unit cost increases in California and Nevada for CMS' fiscal year 2024. Supplemental benefit expense. We saw a year-over-year increase in our supplemental benefit expense in 2023 but importantly, this was consistent with our budget forecast. In 2024, we continue to contemplate higher supplemental benefit expense as part of our full year outlook. This is largely a result of our successful vendor transition that has improved Black Card service levels. While we have incorporated this as an area of MBR headwind in our 2024 outlook, it is also contributing to improved retention and member engagement on our critical clinical initiatives. And lastly, our clinical initiatives. We've identified numerous care and medical management opportunities to improve quality outcomes and utilization turns in 2024. Our first quarter outlook generally reflects the regular seasonality of our MBR experience. As a reminder, utilization is typically higher in the first quarter than the full year average. Part D is also much less profitable in the first half of the year as compared to the second half, particularly in the first quarter. This year, our guidance also reflects an extra day of medical expense in the first quarter due to the leap year and a higher mix of pre midyear sweep new members in Q1 relative to prior years. Additionally, we expect our SG&A ratio seasonality to be less pronounced in the back half of this year as we gain economies of scale across the enterprise. As we head into 2024, we are making changes to our ACO REACH business and reporting. Given the immense opportunity we see in Medicare Advantage, particularly over the next few years as we benefit from our competitive positioning on Stars and risk adjustment, we are reallocating our time and human capital towards MA and eliminating downside risk in the ACO REACH program. Going forward, revenue from the program will be reported on a net basis, meaning that we will no longer recognize the full benchmark risk as gross revenue. The difference in accounting is due to our decision to capitate a provider to take risk on the ACO REACH population for 2024. Under this arrangement, we will recognize a nominal amount of gross profit and not share any ACO REACH program deficits. The changes to our ACO REACH accounting are reflected in the 2024 outlook I previously provided. Pro forma for changes in revenue recognition, year-over-year revenue growth is expected to be 41% at the midpoint of our outlook range. We have included a financial supplement on our Investor Relations page with additional detail. In conclusion, we are well positioned to execute on our 2024 objectives and are excited for the opportunity ahead of us in 2025 where we expect our competitive advantages to compound even further. With that, let's open the call to questions. Operator?
