I will begin my review of our 2025 financial results focusing on our fourth-quarter performance. I will follow up with the introduction of our non-GAAP financial guidance for 2026 and some considerations to help you better understand our financial outlook for this year. We had very strong commercial and financial performance in 2025, marked by focused execution on driving top-line growth and generating strong cash flow while strengthening our balance sheet and continuing to manage our cost structure. We've entered 2026 in a position of strength with a solid foundation, which we can continue to build upon to deliver on our long-term growth strategy. Starting with slide eight, total revenue in the fourth quarter was flat year over year at approximately $12.5 billion. Our growth portfolio continued its positive momentum, with revenue increasing 15% to $7.4 billion and representing close to 60% of our total revenue in the quarter. Key brands including Reblozyl, Breyanzi, Camzyos, and our IO portfolio all achieved significant growth and were further supported by our early launches of CoBinfy and Qvantik. Within the legacy portfolio, higher revenue from Eliquis was offset by the continued impact of increased generic volumes across several other brands. All in, we are very pleased with the results in the fourth quarter and the full year. As our growth portfolio performance continues to reshape and redefine Bristol-Myers Squibb Company as we strive to be one of the fastest-growing pharmaceutical companies into the next decade. Turning to product performance on slide nine, starting with oncology. Opdivo again delivered solid growth in the fourth quarter, with revenue up 7% to nearly $2.7 billion. This was driven by new indications and continued share growth within the first-line non-small cell lung cancer setting. Qvantik's launch continued to progress well with revenue of $133 million in the quarter. With Opdualag, delivered another quarter of strong double-digit growth, driven by demand in the U.S. where it remains a standard of care in first-line melanoma. Turning to slide 10. Reblozyl delivered 21% growth with performance reflecting solid uptake across first and second-line MDS-associated anemia patients. Over the past two years, we've delivered a very strong launch for Reblozyl. In cell therapy, Breyanzi's fourth-quarter revenue continued to show impressive growth with revenue up 47%, driven by its desirable profile and continued strong demand across its approved indications. We continue to be encouraged by Breyanzi's growth prospects into 2026. Moving to cardiovascular on slide 11. Eliquis delivered nearly $3.5 billion in fourth-quarter revenue, an increase of 6%. This was driven by demand growth and market share gains with U.S. revenue increasing 4%. Turning to Camzyos, revenue in the fourth quarter grew 57% to $353 million, benefiting from continued demand growth globally. In the U.S., we expanded the number of physicians who are prescribing the drug, and outside of the U.S., we have now launched in over 50 countries. Now moving to immunology. Global revenue of Sotyktu grew 3%. We look forward to our upcoming PDUFA date for psoriatic arthritis and our phase three readouts for lupus and Sjogren's disease. I will wrap up by reviewing our product performance for the quarter on slide 12 with neuroscience. CoBinfy revenue in the fourth quarter was $51 million, with continued steady uptake among prescribers and patients. CoBinfy's uptake has surpassed all schizophrenia comparators and relevant analogs in the first year of launch, and we continue to expect steady growth throughout the year. Let's move to the P&L on slide 13. As expected, gross margin declined 210 basis points in the fourth quarter to 71.9%, driven primarily by product mix, notably Eliquis and Revlimid. Regarding our operating expenses, we made significant progress during 2025 against our $2 billion strategic productivity initiative. As of the end of the fourth quarter, we delivered on a target of approximately $1 billion in savings in 2025, and are on track to realize the remaining billion dollars over 2026 and 2027. Excluding in-process R&D, operating expenses for the full year were $16.6 billion, a decrease of $1.2 billion from 2024. This reflects our ongoing cost savings program partially offset by continued investment behind growth initiatives. Our effective tax rate in the quarter was 22.1%, compared to 19.9% in the prior year. With the effective tax rate in 2025 reflecting the one-time non-tax deductible in-process R&D charge related to the Orbital acquisition. Overall, diluted earnings per share were $1.26 for the quarter, and full-year diluted earnings per share came in at $6.15. Both include a net charge related to in-process R&D and licensing income, which totaled 60¢ per share in the quarter and $1.40 for the full year. Now turning to the balance sheet and capital allocation highlights on slide 14. Our financial position remains strong with approximately $11 billion in cash equivalents and marketable securities as of 12/31/2025. We completed our targeted $10 billion of debt paydown ahead of schedule and generated strong cash flow from operations of approximately $2 billion in the fourth quarter. In terms of capital allocation, we continue to ensure we employ a strategic and balanced approach. Business development remains a top priority, while also returning cash to shareholders through our commitment to the dividend. Now let me walk you through our non-GAAP 2026 guidance on slide 15 starting with revenue. As Christopher Boerner mentioned earlier, we estimate revenue to be between $46 and $47.5 billion in 2026. We expect our gross margin to be between 69 to 70%. This reflects the impact of product mix, notably the combination of higher Eliquis and lower Revlimid and Pomalyst revenue. We expect total operating expenses to decline from 2025 levels to approximately $16.3 billion. Our cost savings program has provided us with the flexibility to increase commercial where appropriate and support newer development programs, such as our partnership on pemigatinib and our orbital therapeutics program. Even with these investments, we expect to reduce costs year over year. We are expecting our OI and E expense of approximately $700 million, which reflects the expiry of our royalty-bearing license of diabetes products at the end of 2025. We expect to maintain our tax rate of approximately 18%. Considering these factors, we expect to deliver non-GAAP earnings per share in the range of $6.05 to $6.35. Before closing, let me provide some insight regarding our expected quarterly progression of revenue for 2026. As it relates to quarterly phasing, we expect our typical sequential revenue decrease in the first quarter due to the seasonal inventory destocking we see each year following the build in the fourth quarter. And two points on Eliquis. First, anticipate that the second-half revenue will trend higher than the first half of the year. And second, in terms of Eliquis-specific updated guidance. We currently expect 2027 Eliquis sales compared to 2026 to show a step down in the range of $1.5 to $2 billion, which is broadly consistent with analysts' existing estimates. In closing, our strong performance in 2025 demonstrated our confidence in our ability to deliver long-term value for our patients and shareholders. We remain focused on executing our growth strategy, advancing our pipeline, and optimizing our cost structure. We look forward to updating you on multiple data readouts this year. And with that, now turn the call back over to Chuck Triano for Q&A.
