Thanks, Mac. Good morning. And thank you for joining us. It was a pivotal year for Altria, as we made significant progress in pursuit of our vision, by enhancing our smoke-free product portfolio, while our businesses performed well in a challenging environment. We grew adjusted diluted earnings per share by 2.3% and continued our long history of rewarding shareholders by delivering nearly $7.8 billion in dividends and share repurchases. Throughout 2023, we took several transformative steps that we believe position us for sustained success in the U.S. nicotine space, including completing our acquisition of NJOY and fully integrating it into our family of companies, Making exciting progress on our promising smoke-free pipeline including launching on! PLUS internationally in Sweden, one of the world's largest modern old tobacco markets. Continuing preparations to bring heated tobacco products to market. This includes heated tobacco stick products through Horizon, our joint venture with JT, and our heated tobacco capsule product SWIC and advocating for a responsible and well regulated e-vapor market including stepped up enforcement against the listed disposable products. Our vision continues to guide our actions and we believe that our growing portfolio of smoke-free products positions us well to lead in the evolving nicotine space. My remarks this morning will focus on our view of the U.S. nicotine space and our progress in each of the smoke-free categories. I'll then hand it over to Sal, who will provide an update on consumer and industry dynamics and further detail on our business and financial results. Let's begin with the operating environment. We estimate that total industry equivalized nicotine volumes increased approximately 3% for the year, and approximately 1% over the past five years on a compounded annual basis, driven by the growth of illicit flavored disposable e-vapor products. This new estimate mark stayed changed from our previously provided estimates of low-single-digit decline in total nicotine over the past several years. Our new estimate reflects a deeper ongoing analysis of the impact of a list of products on the e-vapor category. We have previously acknowledged the challenges associated with reading illicit market activity that takes place in less traditional channels. And we believe, we have deepened our understanding of market dynamics through improved data sources, information gaps still remain. As a result, we're making some informed assumptions to better reflect the dynamics at play. For example, we account for differences in liquid volume across products, device attributes and usage patterns by equivalizing e-vapor volume across different form factors. We then equivalized e-vapor volume back to cigarettes, our base unit of equivalized volume. Because of the volatility that exists in reading the illicit market, our estimates may change over time and we plan to provide you with our latest and best thinking as it evolves. Of note, our estimate focuses only on usage among age 21 plus consumers. Looking now by category, industry cigarette volumes declined by an estimated 8% last year primarily due to the historical secular rate of decline, the growth of illicit vapor products and continued macroeconomic pressures on smokers. And while we're deeply concerned about growth in illicit product use, we are encouraged that adult smokers continue to transition to smoke-free alternatives, which now represent approximately 40% of total nicotine space. E-vapor continues to be the largest smoke-free category and we have observed an increase and the number of adult vapers driven primarily by those choosing illicit products. Based on our new estimate, we see e-vapor category grew approximately 35% in 2023. We believe the category growth was largely driven by illicit flavored disposable products, which we estimate represents over 50% of the category. We estimate that pod-based products declined approximately 50%, and represent between 15% to 20% of the category. We continue to believe the e-vapor category is in the beginning of a reset and the steps that we have taken since closing the NJOY transaction will allow us to responsibly participate in the category's growth. Let's briefly recap our 2023 actions with NJOY, following the completion of our acquisition on June 1st. First, we strengthened NJOY's supply chain to enable our expansion plans. Our teams work diligently to solidify the entire supply chain from sourcing direct materials through shipment to retail. We now expect to have capacity to support our expansion plans for NJOY moving forward. Next, we prioritize closing inventory gaps at retail and expanding distribution of ACE. For example, prior to closing, a number of stores had ACE pods in distributions, but no devices. While other stores were missing various pod varieties. Our teams have closed inventory gaps in stores that already had distribution, which has significantly improved in stock conditions at retail. During the fourth quarter, we expanded distribution of ACE to over 75,000 stores, surpassing our previously announced goal of 70,000 stores. These stores represent approximately 75% of e-vapor for volume, and 55% of cigarette volume sold in the U.S. multi-outlet and convenience channel. We also introduced NJOY's first retail trade program, which we will -- we believe will help NJOY achieve optimal visibility and product fixture space at retail. Retailers can sign up for the program at various levels with merchandising options designed to position, NJOY's strategically and responsibly to tobacco consumers while creating further awareness of the brand. We're encouraged by our trade partners response to the program with approximately 70% of stores having chosen options that secure premium positioning and the e-vapor fixture for NJOY. Fixture resets are well underway and we expect the majority will be completed in the first half of this year. We believe that achieving manufacturing capacity, supply chain security, and optimal product distribution and placement at retail were necessary precursors to engaging consumers with impactful marketing and promotional offers. Turning to NJOY's business results, NJOY consumer -- consumables shipment volume was approximately 11 million units for the quarter, and 23 million units since closing. NJOY's retail share and the multi-outlet and convenience channel was 3.7% in the fourth quarter. In November, we began testing trial generating bundle offers in a limited number of retail accounts, and the results were very encouraging. Despite the limited reach of these offers, NJOY retail share increased 0.3 of a percentage point nationally in November and another 0.3 in December. While still early, we are excited by NJOY's momentum and remain optimistic about its potential in the U.S. market. We expect to further expand, NJOY promotions and marketing activations in the first quarter, and we anticipate submitting a PMTA for NJOY's age restricted Bluetooth device with non-tobacco flavors in the first half of this year. We look forward to sharing more detail about our plans for the year at CAGNY. Looking more broadly at the e-vapor category, we continue to believe that the current state of the market is intolerable for both legitimate manufacturers and consumers. As I previously stated, the total nicotine space grew in 2023, largely because of illegal flavored disposable e-vapor products. These products are being distributed by companies violating virtually every rule and guidance the FDA has issued since 2016. We are actively engaging with regulators, state and federal lawmakers, air trade partners, and other stakeholders to build awareness of this serious issue and drive marketplace enforcement. While we believe there is still significant work ahead to eliminate these illicit products from the market, we have seen some encouraging actions. In December, the FDA in collaboration with U.S. Customs and Border Production announced the seizure of approximately 1.4 million unauthorized e-vapor products, including Elf Bar and other brands that are popular with underage users. We believe that adopting comprehensive border protection programs is an important step towards clearing the market of illicit products. Additionally, we have worked with legislatures in a number of states that have passed or are considering legislation requiring manufacturers to certify that they have either submitted a PMTA, which is pending or received a marketing order in compliance with FDA regulations. We also initiated litigation in the United States District Court in California relating to the sale of unlawful products. And although this litigation is facing some initial procedural challenges, we remain committed to explore and pursue all litigation opportunities against manufacturers, distributors and online retailers related to sale of unlawful products. A strong course correction is needed to protect the tobacco harm reduction for the millions of adult smokers in the U.S. We've learned from past experiences that complex issues like this require the work of many stakeholders. For our part, we're working with regulators, legislatures, law enforcement and others to address the illicit market. And while the FDA and other authorities are stepping up enforcement, more action is needed. Turning to oral tobacco, the nicotine pouch category experienced sizable growth once again resulting in an estimated 7.5% increased in total U.S. oral tobacco volumes over the past six months. In the fourth quarter, oral nicotine pouches grew 11.8 share points year-over-year and now represent more than 35% of the total U.S. oral tobacco category. On! continued to participate in the category growth as reported shipment volumes increased nearly 33% in the fourth quarter and 39% for the full year. In the fourth quarter, Helix continued its focus on volume growth while improving profitability. Helix applied its analytics and revenue growth management capabilities to be more flexible and efficient with its promotional investments in the marketplace. As a result, orange retail price increased over 47% versus the year ago period, while growing its retail share by 1.1 percentage points. Encouragingly, we continue to see increasing levels of both trial and adoption of the brand with repeat purchases up more than 30% year-over-year, despite the substantial increase in retail price. We remain excited about on! PLUS and its potential in the U.S. market. We believe its long lasting flavor system and proprietary softened material are differentiators in the category. We continue to see encouraging results from the on! PLUS test launch in Sweden. Consumer research from the fourth quarter indicates that on! PLUS is competitive with the market leading old nicotine pouch products in Sweden, and is seen as a unique offering with a strong repeat purchase rate of over 30% in the e-commerce channel. Given the success of on! PLUS net and smooth net in December, we introduced on! PLUS berry and citrus and 6 and 9 milligram strength variants in the e-commerce channel. We also plan to expand on! PLUS to additional retail accounts and suite. Our teams are on-track to submit the PMTA for on! PLUS in the first half of this year and upon FDA authorization, we expect it will contribute meaningfully to Helix's growth. In heated tobacco, we believe our compelling portfolio of products will appeal to the millions of adult smokers seeking innovative and scalable alternatives to e-vapor products. We are continuing regulatory preparations to bring heated tobacco stick products to the U.S. market through Horizon, our joint venture with JT. We remain on-track to follow-up PMTA for Ploom in the first half of 2025. And we are making continued progress on our heated tobacco capsule product SWIC. While we believe heated tobacco products can play an important role in achieving harm reduction, the category remains nonexistent in the United States. We're encouraged by the progress we made in 2023 and we are committed to achieving long-term leadership in each of the smoke-free categories while delivering strong shareholder returns. Last March, we introduced our 2028 enterprise goals. We provided updates on our progress in this morning's press release and we expect to provide progress updates annually moving forward. We look forward to discussing our exploration of non-nicotine and international mid-teen markets at CAGNY later this month. Turning to our 2024 financial outlook. Our plans include a continuation of our strategy to balance earnings growth and shareholder returns with strategic investments toward our vision. For 2024, our planned investment areas include marketplace activities in support of our smoke-free products and continued smoke-free product research, development and regulatory preparations. We believe the external environment will remain dynamic in 2024, and we will continue to monitor the economy, including the cumulative impact of inflation, tobacco consumer dynamics including purchasing patterns and adoption of smoke-free products, solicity vapor enforcement and regulatory litigation and legislative developments. Considering these factors, we expect to deliver 2024 full year adjusted diluted EPS in a range of $5 to $5.15. This range represents an adjusted diluted EPS growth rate of 1% to 4% from a $4.95 base in 2023. We expect 2024 adjusted diluted EPS growth to be weighted to the second half of the year. Our guidance includes the impact of two additional shipping days in 2024 and assumes limited impact from illicit e-vapor enforcement on combustible and e-vapor volumes. Before I turn it over to Sal, I'd like to take a moment to recognize Murray Garnick, who recently announced his decision to retire from Altria. During his remarkable career, Murray represented Altria and its subsidiaries for nearly 40 years, both as outside and in-house counsel including his last seven as General Counsel, leading the law and regulatory affairs departments. Under his guidance, we have successfully managed significant litigation challenges and established Altria as a leading advocate for tobacco harm-reduction policies in the U.S. We will continue to benefit from Murray's guidance through the first quarter. At which time, Bob McCarter will assume the role of General Counsel. Bob currently leads the management of tobacco health and other litigation. Bob has been with Altria since 2015, and spent 18 years before that representing the company as outside catching. Please join me in thanking, and congratulating Murray on an incredible career. And we look forward to introducing Bob to many of you at CAGNY, and in years to come. And I'll now turn it over to Sal to provide more detail on the business environment and our results.
