Thanks, Katy. Good morning, everyone. Elanco delivered a strong second quarter with meaningful progress in our late-stage pipeline, the successful completion of our ERP integration and exceeded the top end of our guidance range on revenue by $4 million, adjusted EBITDA by $61 million and adjusted EPS by $0.13. We continue to expect this sequential improvement in the first half to continue with an anticipated return to revenue growth in the second half of 2023. We are updating our expectations for the year, raising guidance for revenue, adjusted EBITDA, and adjusted EPS. Starting on Slide 4. Since our last call, we delivered improved operational performance and achieved key milestones advancing our strategy. First, in Q2, we delivered the second consecutive quarter of sequential improvement and year-over-year revenue performance, excluding the ERP blackout impact, driven by strong performance from the U.S. Pet Health business, International Farm Animal and contributions from new products. Additionally, we completed our ERP integration and announced resolution of the EPA Seresto review, confirming the product's continued registration. On debt, we are completing the refinancing of our August 2023 notes today. Next, in the quarter, we saw strong adoption in several EU markets for Adtab, our newly launched oral OTC flea and tick solution; and in July, we launched our Canine Parvovirus Monoclonal Antibody in the U.S. We made significant progress on our late-stage blockbuster pipeline advancing key programs and gaining additional confidence on the differentiation and launch plans. Finally, we issued our 2022 ESG report demonstrating progress on our Healthy Purpose sustainability efforts in our internal operations, customer collaborations and beyond. Focusing now on financial performance, on Slide 5, we provide a view of year-over-year revenue for the first half of the year, excluding the impact of the ERP integration between the first two quarters. Elanco reported a 1% decline in constant currency, demonstrating a marked improvement from the 5% decline in the second half of 2022 and surpassing our guidance expectations of a 2% to 4% decline. Looking now to the key drivers in our four business areas that drove this overachievement. First, U.S. Pet Health. U.S. Pet Health returned to growth in the first half of the year, delivering 1% growth year-over-year. Our strategy to increase share of voice, improve physical availability, leverage innovation, and grow price contributed to the improved performance. The strong parasiticides season contributed to the OTC retail market dispensing growth in both units and total sales, while Elanco execution led to share gain in this market through the first six months of the year. Both Seresto and the Advantage Family grew revenue high-single digits, exceeding expectations, as our new creative campaigns and increase in total distribution points began to payoff. On the vet clinic side, our investment in digital and enhanced sales force effectiveness drove a 36% increase in total touch points in the first half of the year. This deeper engagement with veterinarians and clinics contributed to penetration growth for Credelio and Interceptor Plus and Galliprant. While competition remains impactful in the U.S. vet market, these increased touch points and penetration contributed to the stabilization of our business in this channel. Bobby Modi's team's strategic execution is improving outcomes, and we expect continued positive momentum from this business in the second half as we prepare for an exciting innovation launch window in 2024 and beyond. Next in our International Pet Health business. This business declined 7% in constant currency in the first half. 6 percentage points of the decline was driven by the impact of ongoing demand pressure in the Spain retail parasiticide market. More broadly, we saw continued growth in our Credelio franchise, balanced by slower markets, primarily impacting retail and other key geographies like Italy, China and Japan. The European launch of Adtab surpassed expectations, increasing its expected full year contribution. Our market penetration strategy and quick action has positioned us well in the emerging OTC oral parasiticide market in Europe. We expect improvement in our International Pet Health business in the second half as we leverage innovation and anticipate a better economic environment in Europe compared to the second half of 2022. Now moving to Farm Animal. Our International Farm Animal business, the largest of the four quadrants, grew 4% in constant currency in the first half, driven by strength in poultry, aqua and price. We expect these drivers to remain strong in the second half of the year. The U.S. Farm Animal business declined 5% in the first half, with 4 percentage points driven by supply disruption for cattle vaccines and the remaining driven by implant regulation changes and timing of poultry rotations. These were partially offset by increased adoption of Experior and contribution from NutriQuest. In the second half, we expect stronger performance from our U.S. Farm Animal business, driven by improved vaccine supply, the continued ramp of new products and increased demand for our poultry portfolio. A few comments on Experior. Experior remains an important innovation sales growth driver for this year. Beginning in March, we saw a positive trajectory change in the use of the product, which continued to accelerate through July, resulting in second quarter sales at three times those of the first quarter. Adoption in Canada is tracking on a similar trajectory as the U.S. We continue to focus on expanding use with existing customers and expect to exit the year at an annualized run rate of approximately 60 million to 70 million. Finally, we're encouraged by the recent announcement from Tyson Foods to reintroduce animal-only antibiotics or ionophore into their poultry supply chain. Elanco leads the in-feed poultry solutions area with a variety of tools from nutritionals to our differentiated narasin, an ionophore, products, Maxiban and Monteban, which we expect will be key products in these new programs. As the processor of about one-fifth of all the U.S. chickens, we believe Tyson shift will result in a more sustainable production, improved animal welfare and a positive net impact on Elanco's business. Moving now to Slide 6. Let's look at the strategic drivers of our innovation, portfolio and productivity framework over the past few months. First, with productivity. In April, we successfully completed our ERP integration, simplifying our internal and customer-facing business processes and enabling synergies. Among other things, the simplification offered the ability to engage in a commonly used accounts receivable asset securitization program. This program will provide the majority of the funds to retire our 2023 notes, which we are completing today. Next, onto the portfolio. For Seresto, we're very pleased with the outcome of the EPA's comprehensive review and the confirmed continued registration of the product. We never wavered in our data-driven confidence in the safety profile of Seresto, and we are encouraged by the robust science-based approach taken by the agency. We view the stewardship plan as an opportunity to raise the bar across the collar category. We see the EPA outcome as a positive for the Seresto brand, pet retail, veterinarians and, most importantly, pet owners. We now shift our focus to maximizing the commercial opportunity for Seresto globally, with a product returning to high single-digit growth in the U.S. in the first half of this year. Next, price continues to be strong, driven by the improved capabilities over the last year with 4% growth on a year-to-date basis. We now expect price growth of at least 3% for the full year. With the encouraging pipeline progression and our expectations regarding differentiation, we're increasing our investment in the U.S. Pet Health business. The commercial organization, led by Bobby Modi, in partnership with Tim Beddington, leading our market strategy efforts, are focused on building on our digital progress, adding experienced animal health marketing talent and accelerating our efforts to expand our field force. This investment is focused on maximizing the potential of our total pet health portfolio, including our launches this year and the innovation we expect to launch in 2024 as we globalize the portfolio over time. Finally, moving to Slide 7, I'll provide an update on our late-stage pipeline. Overall, the pipeline is strengthening with important progress in key late-stage programs and portfolio-enhancing approvals in major markets across species. Ellen de Brabander and her team are driving early-stage advancements, moving exciting projects from research into clinical development as we continue to build the components needed to deliver consistent, high-impact innovation. In the U.S., we launched our canine parvovirus monoclonal antibody, a highly anticipated treatment for one of the most contagious and deadly dog viruses. The supply chain is enabling responsiveness and the product is already saving dogs' lives, driving reorders. As expected, in 2023, demand is outpacing supply due to the anticipated capacity limitations in our facility at launch. We are on track to ramp up our capacity to 10x today's volume to support the expected increase in demand in the coming years. This year, we expect revenue contribution of $5 million to $7 million. However, we see this product as an important growth driver to both the top- and bottom-line starting in 2024 and expect blockbuster contribution as we expand outside the U.S. over time. As we've shared previously, we took a phased approach to filing our late-stage potential blockbusters. With three products in late-stage review, we appreciate the predictable nature of the FDA process, driven by ADUFA, the Animal Drug User Fee Act. Our views about our products are based on the data we've generated and, of course, are subject to the approval process. Today, we are proud to share that we believe the FDA has all the data necessary to approve our differentiated JAK inhibitor for canine dermatology. We are encouraged by this product's progress and believe it will be highly valued by veterinarians and pet owners. Additionally, by the end of August, we expect the FDA will have all the data necessary to approve our broad spectrum parasiticide for dogs, and for Bovaer, our methane-reducing product for cattle. Based on this, we continue to see a path towards FDA approval in the first half of 2024 for all three of these potential blockbuster products. With the developments in the parasiticide space, over the last month, our confidence regarding the expected differentiation for our canine broad spectrum parasiticide has increased. Our product, upon approval, will be known as Credelio Quattro. A combination of lotilaner and three other active ingredients, it will focus on fleas and ticks as well as broad coverage of internal parasites, including heartworm, round warm and tapeworm. The product is seeking to demonstrate 100% heartworm prevention after one month. We expect that differentiated coverage of Credelio Quattro and the differentiation of our JAK inhibitor for dermatology, this will allow Elanco to provide a more comprehensive and valuable portfolio of canine products to veterinary clinics in 2024. Shifting to Bovaer, our first-in-class innovation to enable methane reduction in cattle where we will focus our initial efforts first on dairy. Based on the wide body of research supporting the product's approval in many countries around the world and our discussions with the FDA, we're highly confident in the path to approval for this product in the first half of 2024. Importantly, we believe we have secured necessary launch supply with a contract manufacturer, a key component of the 2024 growth contribution. As we pioneer new ground with products to reduce environmental impact, we are working across the value chain to validate, aggregate and create value for reducing livestocks' environmental impact and we are encouraged by the interest from the food chain. Regarding our IL-31 short-acting monoclonal antibody for canine dermatology, we now expect a differentiated product profile relative to the current technology. However, our expectation for U.S. approval has shifted to 2025 as a result of the USDA's increased data requirements across monoclonal antibody platforms. We remain confident in the product and its value in our overall portfolio. Our innovation sales for 2023 continue to track to our guidance of $210 million to $250 million, and we still expect to have incremental innovation revenue of $600 million to $700 million by 2025. The shift of IL-31 is balanced by increased expectations for our other late-stage potential blockbuster products as well as confidence in our views on Experior, Parvo and Adtap. Over the last several months, our launch revenue expectations for our late-stage potential blockbusters have increased as a result of higher confidence in our differentiation, enhanced launch plans and the evolving competitive landscape. We understand delivering on our opportunities and our pipeline go well beyond getting the product over the regulatory finish line, and we are investing in talent and capabilities to fully capture the value of our portfolio in 2023 and beyond. Now I'll pass it to Todd to provide more on the second quarter results and financial guidance.
