Thank you, Stéphane, and hello everyone. Today, I will review our financial performance for both the fourth quarter and the full year of 2023. I'll also provide our financial framework for 2024. Let me start with a review of our commercial performance this year. In the first half of 2023, we reported product sales of $2.1 billion, with the majority of sales from advanced purchase agreements signed for delivery in 2022 that were deferred into 2023. We do not expect these sales to repeat in 2024. In the second half of 2023, we recorded $4 billion in sales from seasonal endemic demand and an additional $600 million from deferred revenue related to Gavi. Sales in the fourth quarter were $2.8 billion, with $0.8 billion in sales in the U.S. and $0.6 billion in Europe and $1.4 billion in the rest of the world, including the deferred revenue from Gavi. For the full year, 2023, product sales were $6.7 billion, comprised of $1.7 billion in sales in the U.S., $1.4 billion in Europe, and $3.6 billion in the rest of the world, again, including deferred revenue from Gavi. Moving to side 10. As mentioned, net product sales were $2.8 billion this quarter, a 43% decrease from last year. This was largely attributable to the anticipated reduction in sales volume, which was partially offset by a higher average selling price. This decrease is indicative of the evolving market dynamics as we navigate the transition of the COVID-19 vaccine market towards a more predictable seasonal pattern like traditional flu vaccines. Cost of sales was $929 million, down from 39% of net product sales in the previous year to 33% this year. This is a demonstration of our strategic efforts in Q3 to resize our manufacturing footprint, which as expected, led to additional charges in Q4 of $169 million, primarily related to the wind down of certain contract manufacturing operations. Additionally, faster sales also includes an inventory write-down of $322 million, reflecting revised demand forecasts. R&D expenses increased by 16% to $1.4 billion. This uptick reflects our commitment to advancing our late-stage clinical development programs, particularly with our RSV vaccine, CMV vaccine, combination vaccine against flu and COVID-19, as well as our INT program. The increase also included an upfront payment of $120 million associated with the strategic research and development collaboration with Immatics. SG&A expenses were $470 million, up 25% year-over-year. The increase in spending was primarily due to the expansion of our commercial operations, particularly in the U.S. market. Income tax was a benefit of $147 million for the fourth quarter of 2023, largely attributable to the tax benefits as part of finalizing our 2022 U.S. tax return. Net income for the quarter was $217 million, compared to $1.5 billion in the fourth quarter last year. Diluted earnings per share was $0.55 compared to $3.61 in 2022. We closed the quarter with a strong cash position of $13.3 billion, which is slightly higher than the $12.8 billion we had at the end of the prior quarter. Now, let's turn to our annual performance on Page 11. Net product sales for the full year of 2023 were $6.7 billion, a decrease of 64% from the previous year, mainly due to lower sales volume of our COVID-19 vaccine. As mentioned earlier, this includes the recognition of $0.6 billion from the deferred revenue related to Gavi. Excluding this item, our sales of $6.1 billion were still in line with the framework we provided for the full year. Cost of sales for the full year represented 70% of net product sales, a substantial increase from 29% of product sales in 2022. This shift is largely attributable to our strategic efforts to optimize our manufacturing operations, resulting in charges of $1.6 billion, and other manufacturing and distribution costs over reduced sales volume. Overall, cost of sales came in at $4.7 billion, slightly below the $5 billion we provided in our latest framework. Research and development spend was $4.8 billion, and SG&A was $1.5 billion, both in line with our expectations. Our income tax provision was $772 million for the full year 2023. During our Q3 earnings call, we discussed the requirement under GAAP to establish a valuation allowance against deferred tax assets, when the current year and cumulative income projection for the next three years is in a loss position. It's important to note that future income from products not yet approved by regulators are excluded from these income projections, which restricts us to just our COVID vaccine, and it does not include expected future launches. This valuation allowance does not impact cash flows, future tax returns or the company's ability to utilize deferred tax assets in future periods. Net loss for the year was $4.7 billion, compared to net income of $8.4 billion last year. The decrease in profit was primarily due to lower product sales and higher R&D expenses in 2023. Diluted loss per share was $12.33, compared to diluted earnings per share of $20.12 in 2022. So now let's move to slide 12. We wanted to provide you additional perspective on our full-year financial results by presenting them alongside a summarized version that excludes the impact of the Gavi deferred revenue recognition, our resizing charges, and the tax valuation allowance. Our total GAAP net loss for the full year was $4.7 billion. However, when excluding these primarily non-cash items, the net loss is reduced to $1.6 billion. Now let's turn to our 2024 financial framework on slide 13, which is mostly in line with what I shared on our Q3 call. We expect net sales for 2024 of approximately $4 billion, which we think will be a low point, as we expect to return to growth in 2025. Sales in the first half of the year are expected to be approximately $100 million, reflecting the strong seasonality of respiratory vaccines. We expect cost of sales of approximately 35% of product sales, in line with our cost of sales framework which we introduced in our Q3 earnings call last year. For R&D we expect full year expenses to be approximately $4.5 billion, down from $4.8 billion in 2023, and for SG&A, we expect full year expenses to be approximately $1.3 billion, down from $1.5 billion in 2023. We also expect taxes to be negligible in 2024. In our Q3 earnings call, I provided our Moderna operating principles, which largely centered around a very disciplined approach to capital allocation. Our number one priority has been, and will continue to be, reinvesting in the business. In addition to the investment into our pipeline, we expect capital expenditures in 2024 to be approximately $0.9 billion, as we mostly complete the construction of our facilities across the globe. Our teams are laser-focused on operational improvements for both expense management and working capital. As a result, we expect to end 2024 with approximately $9 billion in cash. I will now turn the call over to Stephen.
