Thanks, Ralph. Good morning, everyone, and thanks for joining our call today. 2023 was a very strong year for our company with consistent performance and sustained growth. We executed with discipline across our businesses. We delivered for our customers and patients, our employer clients, our health plan partners in the others we serve. And with our expertise and diverse breadth of capabilities, we continue to improve affordability and clinical outcomes as well as continuing our work to expand access and choice. As we look forward, we're carrying momentum into 2024 and we expect another strong year of performance in growth. Now today, I'll focus my comments on key strategic drivers of our performance last year and how we continue to evolve and advance our business to sustain our impact on growth. Brian will then walk through additional details about our performance for 2023 as well as our outlook for 2024. Then we'll take your questions. Now before I go into our results, I want to comment on the announcement we made earlier this week, we reached a definitive agreement to sell our Medicare businesses to HCSC. We expect this transaction to close in early 2025, following customary legal and regulatory approvals. And while we continue to see the seniors market as an attractive growth market, we concluded that our Medicare businesses well large at about $12 billion in revenue would require sustained investments and focus and capital as well as dedicated resources that were disproportionate with their size within the Cigna Group's portfolio. Additionally, with Evernorth's broad high-performing service portfolio, we will continue to serve the needs of seniors and grow our business. I would note that as part of our agreement, HCSC will be served by Evernorth for continued services for the customers we are selling. Additionally, we're expanding the reach of Evernorth's portfolio and see significant continued growth opportunities in Government services, including Medicare. Now as we consider the performance of our Medicare Advantage business in 2023, in the fourth quarter, results were in line with our expectations. And for the year, we balanced high-quality and competitive benefits offerings, continued target market expansion, and disciplined pricing activity. Now with that, let's move into our 2023 headlines. Probably for 2023, we exceeded our financial commitments. Full year total revenue, we delivered $195.3 billion. Full year adjusted earnings per share was $25.09 and cash flow from operations of $11.8 billion. This performance extends our track record of delivering consistent positive results, in the face of dynamic market conditions. It speaks to the power of our franchise and the purposeful way we've constructed our company, continuing to build on the strength of Cigna Healthcare, while also shaping and expanding our Evernorth Health Services platform to lead the way in addressing evolving needs in the marketplace. As a result of our focus, discipline and sustained execution, over the past decade, we've delivered adjusted EPS growth of more than 13% on an annualized basis. In the five years since our acquisition of Express Scripts, we've achieved or surpassed every goal we established for the combined company. Through 2023, we've grown revenue by over $50 billion and met or exceeded our adjusted EPS objectives each year. And we've returned $27 billion to shareholders through share repurchase as well as attractive dividend payments. In 2023, after increasing our outlook for adjusted EPS twice over the course of the year, we had a strong finish and delivered full year adjusted EPS that was better than expectations. In short, we've demonstrated the ability to profitably evolve our business and services that we provide over many years, which enable us to continue to deliver on our commitments and growth. Now I'll discuss our performance in greater detail. I'll start with Evernorth. In our Express Scripts business, we successfully implemented the single largest contract ever in the pharmacy benefits industry. Throughout 2023, thousands of coworkers collaborated and worked with dedication, so we'd be ready to begin fulfilling, well over 400 million annual prescriptions for 20 million Centene customers starting at the beginning of this year. Additionally, Centene was amongst hundreds of additional clients that were ready to serve in 2024 and I'm proud to say we're off to a strong start. The good work of our team has helped us meet the needs of our customers and reinforce the trust that Centene and of the clients place in our company. Another Evernorth highlight for 2023, is that we once again advanced industry-leading innovation. Last spring, we launched a series of innovations, including ClearCareRx, to support affordability, additional transparency and broader choice as well as independent Rx to partner and enable more closely with independent pharmacies. Then in November, we have further an expanding choice for clients funding their pharmacy benefits with Express Scripts clear network. We were the first to launch a scaled pharmacy network model offering cost-based pricing. In addition, our accelerated growth businesses with Evernorth fueled our momentum as well. Accelerated growth in Accredo specialty pharmacy and CuraScript SD businesses and in our care services businesses contributed to Evernorth's strong top and bottom line results. With Accredo and CuraScript SD, we are supporting patients and providers with safe and effective use of the growing volume of high-cost clinically compliant specialty drugs. We also continue building out our care service platforms to ensure patients can access care when and how they need it, while also remaining connected with physical sense of care. Our MDLIVE virtual platform, for example, is now available to over 60 million individuals as part of their benefits offering and is supporting the growing volume of care, including over 2.2 million virtual visits in 2023. Our results clearly demonstrate that with Evernorth's leading capabilities were valued and flexible partner for health plans, employers, governmental organizations and health care providers. In Cigna Healthcare, we drove revenue and customer growth through disciplined pricing and medical cost management. We serve employers and individuals who trust us to guide them through the health care system. Our leading clinical care programs could use to support our customers and patients, equipping them with the right information and insights they need to make the best choices for their health and vitality. Our ongoing pricing and continued progress in affordability initiatives in 2023 resulting in a medical care ratio that was better than expectations. Our U.S. Commercial Employer business had an outstanding year with continued strong growth. This was driven by our team's continued success in strengthening our competitive position through improved affordability and leveraging our high-performance networks and digitally enabled services as we expand care access, coordination of care and overall value. Our individual exchange business performed broadly in line with our expectations for the fourth quarter. And with the actions we've taken, we are on track to deliver improved profitability in 2024. In international health, we achieved another positive top and bottom line results. Our high-quality and localized health solutions, supported by our global provider network continue to resonate very well with the globally mobile population and employees of multinational corporations as well as intergovernmental organizations. Now turning to 2024. We will sustain our growth in high performance by sharply focusing on the greatest opportunities with a well-balanced portfolio of complementary businesses and a clear durable strategic growth framework. First, we will drive continued steady predictable growth from our high-performing foundational growth businesses. Pharmacy benefit, U.S. commercial employer and our international health business. Our clients depend on our pharmacy services, for example, and our expertise as well as our leadership in lowering cost for prescription drugs and addressing growing needs such as the high demand for the GLP-1 class of drugs for weight loss in diabetes. We have a long history of guiding appropriate access to medications and providing specialized clinical support and we will continue to build on these efforts with new programs such as our EnCircleRx program. We're also supporting customers in additional ways, including by offering enhanced digital tools to help them better understand the value of their pharmacy benefits. We've been successful in growing our U.S. Commercial Employer business for more than a decade and continue to view this as a growth market for the Cigna Group. We continue to leverage the strength in coordinating a growing number of point solutions for our clients and improving clinical outcomes for our clients. Additionally, we continue to act as a disruptive innovator for small and middle-sized client needs. Second, we will build on further momentum for our accelerated growth portfolio, our fast-growing scaled specialty pharmacy business and our care service businesses. We have tremendous opportunities in these large and expanding markets with our differentiated specialty capabilities, supporting patients with high cost and clinically complex treatments. And within Care Services, we're advancing our capabilities in behavioral health, virtual and home care, as well as coordinated care programs for specific conditions. In summary, for 2024, we will grow our customer and revenue base again and our earnings and operating cash flow at the higher end of our long-term strategic targets. We've increased our expectations for full year 2024 adjusted EPS to at least $20.25, we expect our consolidated adjusted revenues to grow at least 20%, and we expect to generate at least $11 billion of operating cash flow. And we will continue to return capital to our shareholders, including a 14% increase in our quarterly dividend. Now before I wrap it up and turn it over to Brian, I also wanted to mention the announcement we made last month about expanding roles for Brian and Eric. Brian has been our Chief Financial Officer for the past three years and will continue in that role. He will also expand his responsibilities as President and CEO of Cigna Healthcare. Eric is expanding his responsibilities as Executive Vice President of Enterprise Strategy for the Cigna Group, while also continuing as President and CEO of Evernorth Services. Brian and Eric's expanded positions, as well as other leadership changes we announced provide further clarity of our priorities and strategy, as well as the extent of reach and impact lucid to have. Importantly, it also reinforces the depth of our management bench. At our Investor Day on March 7 in New York City, you'll hear more from me, Brian and Eric, as well as other key leaders from across our company. We look forward to sharing with you our views of the expanded addressable markets we see and how we've positioned the Cigna Group to advance our next chapters of attractive growth. Now I'll briefly summarize. With the momentum we carried out of 2023, we are raising our guidance for EPS in 2024. We are building on a strong year of disciplined execution, performance and growth across our company. We deliver for our customers and clients and partners. We kept our commitments to our shareholders, including delivering adjusted EPS for 2023 of $25.09, which was above our outlook, and we generated $11.8 billion of cash flow from operations. We have sharpened the focus of our portfolio further to ensure that we are positioned to drive another strong year for our company. We are building on a consistent track record of disciplined execution, innovation and differentiated partnerships. We've increased our outlook for 2024 and now expect EPS of at least $28.25, and we will continue to advance the strategic deployment of capital, including using the majority of our discretionary cash flow for share repurchase in 2024. We'll have another strong year of performance, continue our track record for more than a decade of delivering against our 10% to 13% long-term adjusted EPS growth target, while maintaining an attractive dividend. And with that, I'll turn it over to Brian.
