Thank you, Kristin. To echo your enthusiasm, 2024 was an excellent year. Our full year performance reflects broad-based revenue growth across segments, species, price, and volume. The foundation of our ability to continually outperform the animal health industry comes from the diversity of our portfolio and the channels and markets in which we lead. For the year, we posted revenue of $9.3 billion, growing 8% on a reported basis and 11% operationally, with 6% driven by price and 5% from volume. We raised our revenue guidance throughout the year and ultimately finished above the high end of our initial range. Adjusted net income grew 10% on a reported basis and 15% operationally to $2.7 billion. Global revenue growth was driven by our companion animal portfolio, which grew 14% operationally. Leading the way, our Simparica franchise posted $1.4 billion in revenue on the year, growing 28% operationally. Simparica Trio exceeded $1 billion in revenue globally. Simparica Trio remains the number one selling canine parasiticide in the US and a trusted choice for vets and pet owners. As Kristin mentioned, triple combination treatments are the fastest growing segment in animal health and are less than 40% of prescription treatments, signaling significant room for continued growth. In OA pain, we continue to see increased adoption. Librela and Solensia reported combined revenue of $581 million globally for the year, growing 80% operationally. Over a decade since our first launch, our key dermatology franchise posted operational growth of 17%, generating $1.6 billion in revenue. We remain steadfast in our confidence to grow the franchise in the face of competition, and we delivered strong double-digit growth balanced across both Apoquel and Cytopoint. We expect continued market expansion, driven by higher compliance and new patient growth, as we have highlighted that a significant portion of this market remains untreated or undertreated. Lastly, our livestock portfolio also had a strong year with $2.9 billion in revenue or 5% operational revenue growth driven primarily by price while volume growth faced headwinds from the MFA divestiture. On an organic operational basis, livestock grew 7%. Moving on to segment performance for the year, both the US and international segments saw impressive double-digit revenue growth. The US posted $5.1 billion in revenue, growing 11% on the year, while our international segment reported revenue of $4.1 billion, growing 10% operationally for the full year. US growth was led by our companion animal portfolio, which grew 15%, driven by the performance of our Simparica franchise, our OA pain mAbs and market expansion across our key dermatology franchise. The Simparica franchise reached nearly $1 billion in revenue, growing 26%. Simparica Trio was a primary growth driver with $918 million in sales, growing 30%. With high vet and pet owner satisfaction, Trio is the leading parasiticide product in the US. Our ability to grow our volume double digits, while simultaneously taking price by being more targeted in our promotions highlights our first-mover advantage. Our OA pain mAbs reported $271 million in sales in the US, growing 197%. In its first full year in the market, Librela generated $201 million in sales and reached blockbuster status in the US market faster than any product in our history, where it is already the first-line choice for severe OA cases. With nearly 40% of dogs suffering from OA at some point in their lifetime, we are confident that Librela will be a contributor to growth for years to come. Solensia posted $70 million in US revenue for the year, growing 58%. For the year, Solensia accounted for over 70% of clinic revenue in the feline OA category and has continued to substantially grow the market since launch. Key dermatology had an exceptional year, posting growth of 16% on $1.1 billion in sales. As we highlighted, there is a substantial population of untreated or undertreated dogs with derm conditions. Our double-digit volume growth in key dermatology demonstrates our ability to convert those patients to our differentiated portfolio of treatment options and highlights the continued expansion opportunity in the derm space. US livestock business declined 1% on the year due to the MFA divestiture, which closed on October 31. Excluding the impact of MFAs, our organic operational US livestock growth was 6%, which was driven by improved supply of ceftiofur. Moving on to our international segment. Revenue grew 5% on a reported basis and 10% operationally for the year. International performance was favorably impacted by price increases, especially in high inflationary markets, including Argentina, which contributed more than 1.5% to our total company growth for the year. Our international companion animal growth was driven by our Simparica, key dermatology and OA pain mAbs franchises. Our Simparica franchise grew 32% operationally to $357 million in international sales. Performance was driven by Simparica, growing 29% operationally to $212 million in sales, driven by performance in Latin America and Eastern Europe. Simparica Trio grew 39% operationally on $145 million in sales, driven by key account growth in Europe, DTC and the positive impact of our Q1 China launch. Key dermatology posted revenues of $551 million for the year, growing 18% operationally. Performance was driven by Apoquel through new patient growth, especially in Europe. Cytopoint also contributed with new patient growth and compliance in existing patients. Internationally, our OA pain mAbs grew 34% operationally, posting $310 million in combined revenue. Sales of Librela were $246 million internationally, growing 33% operationally. Solensia sales were $64 million, growing 39% on an operational basis. Our international livestock portfolio grew 8% operationally to $1.9 billion in sales for the year, with growth driven by price as well as strong performance in fish, partially offset by headwinds from swine volumes in China. Moving on to our Q4 results. In the fourth quarter, we posted $2.3 billion in revenue, growing 5% on a reported basis and 6% operationally, with 5% driven by price and 1% from volume. Excluding the impact of our MFA divestiture, our Q4 organic operational growth was 9%, with 4% coming from volume. Adjusted net income of $632 million grew 11% on a reported basis and 9% operationally. Revenue in the quarter was driven by our innovative companion animal portfolio. Globally, our Simparica franchise contributed $324 million, growing 21% operationally. Our key dermatology franchise posted $417 million or 11% operational growth and our OA pain mAbs contributed revenue of $150 million, growing 20% operationally in the quarter. Our livestock portfolio also contributed operational growth of 1%, with $726 million in revenue. Livestock organic operational growth in the quarter was 8%. Our global companion animal diagnostics business grew 10% operationally in the quarter on revenues of $96 million. Now, let's move on to our segment results for the quarter. US revenue grew 4% in the quarter, with companion animal growing 7% and livestock declining 8% due to our MFA divestiture. On an organic operational basis, excluding the MFA impact, US revenue grew 8% in the quarter with 12% livestock growth. In companion animal, US performance was driven by growth in our Simparica, key dermatology and OA pain franchises. Pet owners continue to seek the higher standard of care offered by our innovative products, and vet clinic revenue remains healthy, growing 7% on an average spend per visit basis despite declining visits overall. Our mAbs are driving higher therapeutic visits. Our Simparica franchise posted US growth of 17% with $240 million in revenue for the fourth quarter, led by Simparica Trio. As Kristin highlighted, we expect the triple combination parasiticide market to more than double by 2028, and higher triple combo share amongst puppies is a key indicator of where the market is going. Our key dermatology franchise grew 7% in the quarter, generating $270 million in revenue despite clinic stocking headwind from the Apoquel Chewable launch last year. Derm visits were 4% in the quarter, highlighting the willingness of pet owners to treat itch. Cytopoint was the largest driver of growth, driven by preference for injectable treatments. Apoquel growth continues to be driven by expansion of Apoquel Chewable, benefiting from increased conversion and compliance driven by alternative channels. Our OA pain mAbs, Librela and Solensia posted a combined $71 million in US sales in Q4, growing 22%. Our growth in the quarter is reflective of headwinds from initial clinic stocking in Q4 of 2023. Librela, now entering its second year in the market, generated $53 million, growing 21% on the quarter and reaching more than 1.2 million patients. We remain confident that the market opportunity is significant. Pain-related vet visits increased 15% in the fourth quarter, highlighting the demand that has propelled Librela to the fourth largest product in our US business and the most successful launch in animal health history. Organic operational growth in US livestock of 12% was primarily driven by the timing of supply of ceftiofur and volume growth in Draxxin. Moving on to our international segment for the quarter. Revenue grew 6% on a reported basis and 10% excluding the impact of foreign exchange. Companion animal grew 13% operationally and livestock grew 6% operationally. The MFA divestiture did not have a material impact on our international organic operational growth. Our international companion animal portfolio growth was driven by our key dermatology products, our Simparica franchise and our OA pain mAbs. Our key dermatology products grew 19% operationally with sales of $147 million in the quarter. Growth in key dermatology was driven by new patients and increased share for both Apoquel and Cytopoint, driven by field force execution and brand marketing campaigns. Preference for chewables continues to increase with conversion to Apoquel Chewable in Europe now at 50%. We saw 32% operational growth in our Simparica franchise internationally with revenue of $84 million on the quarter. Simparica was the main growth driver, growing 33% operationally on $53 million in revenues. Simparica Trio grew 30% operationally with $31 million in revenues. Internationally, our OA pain mAbs grew 18% operationally, posting $79 million in combined revenue. Librela posted sales of $62 million in the quarter, growing 15% operationally. We see continuous growth in prescribing rates and penetration and reorder rates remain high. Solensia growth of 28% operationally on $17 million of sales is driven by increases in both returning and new OA patients. International livestock reported sales of $477 million in the fourth quarter, growing 6% operationally. Growth came primarily from price in hyperinflationary markets and in cattle. Moving down the P&L. Full year adjusted gross margins of 70.7%, grew 50 basis points on a reported basis. Foreign exchange had an unfavorable impact of 40 basis points. Excluding FX, we saw higher margins due to price and favorable mix, partially offset by higher manufacturing costs. Adjusted operating expenses increased 10% operationally for the year. Growth was driven primarily by SG&A increases of 9% operationally, largely due to higher compensation-related expenses due in part to company performance. Full year G&A growth is inclusive of our Q4 growth of 11% operationally, reflective of the acceleration of certain demand-generating activities into Q4 of 2024. R&D spend grew 12% operationally for the year on higher compensation-related expenses due to company performance and increases in project spend related to internal portfolio advancement. Adjusted net income grew faster than revenue at 15% operationally. Adjusted diluted EPS grew 17% operationally for the year. We remain committed to reinvesting in the business while returning capital to shareholders. In 2024, we repurchased $1.9 billion of
