Thank you, Jeff, and good morning. Today, I will discuss several topics. Our financial results for the fourth quarter and full year 2023, our growth initiatives and our strategy for sustaining profitable growth, our 2024 premium revenue and earnings guidance and an affirmation of our long-term growth targets. Let me start with our fourth quarter performance. Last night, we reported adjusted earnings per diluted share of $4.38 on $8.4 billion of premium revenue. Our fourth quarter results and performance metrics demonstrated strong medical cost management and operating cost discipline. Medicaid continued to perform well, withstanding the impacts of the unprecedented redetermination process. Medicare experienced higher than target medical costs, consistent with prior quarters and Marketplace performed very well despite the late in-year medical cost seasonality typically experienced. Our fourth quarter completes a strong year of operating and financial performance. Full year adjusted earnings per share of $20.88 represents 17% year-over-year growth, squarely in line with our long-term target range of 15% to 18% and 6% above our initial 2023 guidance of at least $19.75. Our full year premium revenue of $32.5 billion represents 5% year-over-year growth, and our pretax margin of 4.8% is at the high end of our long-term target range heading into 2024. In Medicaid, our flagship business representing over 80% of revenue, we reported an 88.7% MCR for the full year, which is within our long-term target range. Throughout the redetermination process, we have managed through a number of factors that shape Medicaid's performance, all to land the full year result at a solid jump-off point into 2024. These factors included medical cost utilization, various state corridors and MLR minimums and prospective rate changes. In Medicare, the full year MCR was 90.7%. While the business is profitable, we did not meet our performance expectations due to higher utilization of supplemental benefits, in-home services and high-cost drugs. I am confident that our 2024 bid strategy, adjustments to benefit design and various operational improvements will return the business to target margins in 2024. In Marketplace, we reported a 75.3% MCR for the full year, below the low end of our target range, which reflects the successful execution of our small, silver and stable strategy. This business is now positioned to grow at a rate, which allows us to sustain mid-single-digit margins. In addition to delivering strong financial results, in 2023, we continued to execute on our profitable growth strategy. To recap the growth milestones achieved in 2023. In January, we successfully reprocured our contract in Texas for the state's STAR+PLUS program, retaining all eight regions and likely growing market share. In July, we successfully launched our Iowa Medicaid plan following the RFP, which we had won in a highly competitive process in late 2022. In August, we announced that we were awarded a contract to once again serve Medicaid beneficiaries in the state of New Mexico. In September, we closed on the My Choice Wisconsin acquisition, further expanding our market-leading LTSS franchise. In June, we agreed to acquire Bright Health's California Medicare business, which we have now closed effective January 1, 2024. Also effective January 1 and after another win in a highly competitive bid process, we successfully launched our Nebraska health plan. And finally, on January 1, we launched our expanded California platform, including Los Angeles County, which doubled the size of our business in the state. Collectively, these acquisitions and RFP successes represent $7 billion of annual premium revenue, a portion of which was in our 2023 results, most of which is in our 2024 guidance and all of which will be fully realized in 2025. To say we are pleased with the execution of our 2023 growth initiatives would be an understatement. But the growth story doesn't stop there. The pipeline of opportunities, fueling our future growth trajectory is extremely strong. Let me begin with reprocurements. We have submitted our RFP responses for contract renewals in Florida, Virginia and Michigan. We are proven partners with all three of these states, and we are confident in our ability to retain and grow these relationships. With regard to new state opportunities, including the Florida opportunity just described, there is over $50 billion of total premium revenue opportunity, active or near term, up for bid in several states over the coming years. We have already submitted bids in the states of Kansas and Georgia. With our demonstrated capabilities and referenceable track record, we remain confident in our ability to continue to win new state contracts. With respect to our M&A initiatives, our acquisition pipeline remains robust with actionable opportunities and we are confident in our ability to deliver growth from this key component of our strategy. Since 2019, we have completed eight transactions having acquired over $11 billion of premium for which we paid 22% of revenue. This capital allocation to M&A will continue to be a value driver. Turning now to our 2024 guidance. We project 2024 premium revenue of approximately $38 billion, which is consistent with our previous outlook and represents 17% year-over-year growth. We project 2024 adjusted earnings per share of at least $23.50, representing 13% year-over-year growth. Mark will take you through the detailed guidance build in a few minutes. But in the meantime, let me offer some high-level commentary. Our projected premium revenue growth to $38 billion represents a well-balanced combination of new contract wins, acquisitions and growth in our current footprint, partially offset by the impact of Medicaid redeterminations. With respect to earnings guidance in the core business, in Medicaid, our guidance fully considers the impact of the redetermination process. From a margin perspective, this is playing out as we have predicted. The impact of acuity shifts is real, but not significant. The risk corridors acted as a financial buffer and rates prospective and retrospective are largely capturing the trend impact. On a same-store basis, we are projecting the 2024 Medicaid MCR to be within our long-term range. We expect Medicare to return to mid-single-digit profitability in 2024 as a result of our bid strategy, adjustments to benefit design and operational improvements in the legacy business. Our Marketplace product has been priced right, is competitively positioned and the risk pool has stabilized. We expect the business to achieve mid to high single-digit margins, membership to grow over 30% and revenue to grow 17%. On top of our 2024 earnings per share guidance of at least $23.50, we now have $4 per share of new store embedded earnings, which, as you may recall, represents the expected accretion produced by our new store growth. Mark will review the components of the updated $4 per share in his remarks. Our confidence in our 2024 guidance starts with a high-quality 2023 earnings baseline and then takes a thorough account of all the various factors, exogenous and company-specific, that could impact earnings in 2024. Now, a few comments on our longer-term trajectory. Our 2024 guidance picture is one more data point that validates our long-term targets of 13% to 15% premium growth and 15% to 18% adjusted earnings per share growth. We committed to these targets at our Investor Day last May, and we reaffirm that commitment today. With the majority of the $4 of new store embedded earnings expected to emerge in 2025, we already see a clear outlook to achieving the low end of our long-term EPS growth target in 2025, even before considering the execution of additional growth initiatives and driving growth from our current footprint. In summary, we are very pleased with our 2023 performance, our trajectory to deliver the growth and profitability inherent in our 2024 guidance and the embedded earnings outlook we provided for 2025. Our confidence in continuing to achieve our long-term targets is data-driven as demonstrated by the following historical fact set. We have reprocured approximately $12 billion in existing revenue. We have added approximately $7 billion of new revenue through wins of new or expanded contracts in seven states. From 2020 to 2023, we achieved 21% annual premium growth and 25% annual earnings per share growth. 2024 guidance, 17% premium revenue growth year-over-year, 13% earnings per share growth year-over-year. And for 2025, and we expect to harvest the majority of our $4 per share of embedded earnings. Our strategy is clear and simple. We are in the business of providing access to high-quality health care for individuals relying on government assistance. Our business model is also clear and simple. We take on capitated risk, take or make rates that are commensurate with medical cost trends, and manage those trends to consistently achieve our target margins while maintaining higher standards of quality. The execution of our strategy and business model has been and will continue to be strong which is why we look to the future with a great deal of confidence. In conclusion, I want to extend my special thanks to our 19,000 associates who are dedicated to delivering access to high-quality healthcare to our members. It is my privilege to serve with such a committed and capable group of professionals. With that, I will turn the call over to Mark for some additional color on the financials. Mark?
