(NYSE:ZTS), the world's leading animal health company, today reported its financial results for the third quarter of 2026. "Our third-quarter performance was in line with our expectations. Continued pressure in Companion Animal was partially offset by growth in Livestock and Diagnostics, reflecting the breadth of our portfolio," said Kristin Peck, Chief Executive Officer of Zoetis. "We remain focused on defending our position and directing our resources where they can have the greatest impact. And with the scale, expertise, and pipeline to keep setting the pace of innovation in animal health, we are confident in our ability to create long-term value for customers and shareholders." THIRD QUARTER 2026 FINANCIAL RESULTS The company reported revenue of $2.4 billion for the third quarter of 2026, a decrease of 1% on a reported and an organic operational 1 basis compared with the third quarter of 2025. Net income for the third quarter of 2026 was $591 million, decreasing 18% on a reported basis. Diluted EPS was $1.44, decreasing 12% on a reported basis. Adjusted net income 2 for the third quarter of 2026 was $720 million, decreasing 5% on a reported basis and 7% on an organic operational basis. Adjusted diluted EPS was $1.75, increasing 3% on a reported basis and 1% on an organic operational basis. Adjusted net income for the third quarter of 2026 excludes the net impact of $129 million for purchase accounting adjustments, acquisition and divestiture-related costs and certain significant items. THIRD QUARTER 2026 SEGMENT HIGHLIGHTS Zoetis organizes and manages its commercial operations across two segments: United States (U.S.) and International. Within these segments, the company delivers a diverse portfolio of products for companion animals and livestock, tailored to local trends and customer needs. In the third quarter of 2026: Revenue in the U.S. segment was $1.2 billion, decreasing 6% on both a reported and an organic operational basis relative to the third quarter of 2025. Companion animal revenue decreased 8%, reflecting macro-driven price sensitivity and competitive pressure in dermatology, as well as generic competition. Livestock revenue increased 5% on both a reported and organic operational basis in the quarter, supported by strength across cattle, swine and poultry. Revenue in the International segment was $1.1 billion, increasing 4% on both a reported and an organic operational basis compared with the third quarter of 2025. Companion animal revenue increased 1% on a reported basis and remained flat on an organic operational basis, led by parasiticides and osteoarthritis (OA) pain, while partially offset by lower sales of key dermatology products. Livestock revenue increased 8% on a reported basis and 9% on an organic operational basis, driven by growth in cattle and fish. INNOVATION PIPELINE ADVANCEMENTS AND PORTFOLIO UPDATES Zoetis continued to advance innovation across its diversified portfolio, and remains on track for expected 2026 product approvals, with select approvals anticipated in 2027 now expected in Q4 2026. Regulatory Approvals and Portfolio Expansion In October, Zoetis received U.S. Food and Drug Administration (FDA) approval for Convenia ® RTU for Dogs, a long-acting antibacterial injection for dogs. This is the second major market approval this year, with both achieved ahead of the expected timelines, and expands Zoetis' portfolio of therapies designed to broaden treatment options for dogs. Convenia RTU for Dogs is expected to be available to veterinarians in the first quarter of 2027. Zoetis launched Lenivia ® for dogs in Great Britain and received Swiss approval for Portela ® for cats, expanding access to long-acting osteoarthritis pain relief that can last up to three months with a single injection. During the quarter, Simparica Trio ® received U.S. FDA Emergency Use Authorization (EUA) for the treatment of New World screwworm infestations in dogs and puppies. The authorization adds to Zoetis' existing response, including Dectomax and Dectomax ® -CA1 for other species at risk. Additional approvals from the quarter include: Fostera ® PRRS Needle-free microdose was approved in the U.S. and Mexico to help protect pigs against porcine reproductive and respiratory syndrome. Vanguard ® B Oral received an additional claim in Brazil to help protect dogs against Bordetellabronchiseptica. Vanguard ® crLyme received an additional claim in Canada to help protect dogs against subclinical arthritis caused by Borrelia burgdorferi. Alfaxan ® Multidose4% was approved in Japan and Mexico for sedation of cats. New Peer-Reviewed Research and Zoetis Medical Hub Launch A peer-reviewed study published in Parasites & Vectors found that dogs treated with Simparica Trio had significantly lower average heartworm counts than dogs treated with NexGard ® Plus, with few dogs in the Simparica Trio group having adult heartworms at the study's conclusion. The study is available through the newly launched Zoetis Medical Hub, which brings together medical expertise and peer-reviewed research.

NOTES TO RECONCILIATION OF GAAP REPORTED TO NON-GAAP ADJUSTED INFORMATION CERTAIN LINE ITEMS (UNAUDITED) (millions of dollars) (1) Acquisition and divestiture-related costs include the following: Three Months Ended Nine Months Ended September 30, September 30, 2026 2025 2026 2025 Acquisition-related costs (a) $ 2 $ — $ 6 $ 1 Total acquisition and divestiture-related costs—pre-tax 2 — 6 1 Income taxes (b) — — 1 — Total acquisition and divestiture-related costs—net of tax $ 2 $ — $ 5 $ 1 (a) Acquisition-related costs represent external, incremental costs that directly relate to transacting and integrating businesses, included in Restructuring charges and certain acquisition and divestiture-related costs. (b) Included in Provision for taxes on income. Income taxes include the tax effect of the associated pre-tax amounts, calculated by determining the jurisdictional location of the pre-tax amounts and applying that jurisdiction's applicable tax rate. (2) Certain significant items include the following: Three Months Ended Nine Months Ended September 30, September 30, 2026 2025 2026 2025 Other restructuring charges and cost-reduction/productivity initiatives (a) $ 30 $ 4 $ 125 $ 11 Business process transformation program (b) 7 8 18 26 Certain asset impairment charges (c) 89 — 89 27 Net loss on sale of business (d) — — — 3 Other 7 (4 ) 9 (5 ) Total certain significant items—pre-tax 133 8 241 62 Income taxes (e) 30 (1 ) 51 8 Total certain significant items—net of tax $ 103 $ 9 $ 190 $ 54 (a) For the three and nine months ended September 30, 2026, primarily driven by employee termination costs under a comprehensive cost and productivity program, with the nine-month period also reflecting employee termination costs from additional organizational structure refinements, included in Restructuring charges and certain acquisition and divestiture-related costs. For the three and nine months ended September 30, 2025, primarily related to a transition from internal to external innovation and manufacturing of certain products and the closure of a related site, included in Restructuring charges and certain acquisition and divestiture-related costs. (b) Represents costs related to our multi-year business process transformation program, which includes the implementation of a new enterprise resource planning (ERP) system, related digital technology solutions and other related costs, included in Selling, general and administrative expenses and Cost of sales. This comprehensive program is a major global and cross-functional company-wide effort that we believe will transform how we work across our business and contribute to all of our strategic priorities. Due to the nature, scope and magnitude of this investment, these costs are incremental transformational costs that are far in excess of the historical normal level of spending to support operations and are not expected to recur in the foreseeable future. (c) For the three and nine months ended September 30, 2026, represents impairment charges on in-process research and development assets, acquired from PetMedix in 2023, resulting from updated estimates of development and commercial assumptions, included in Other (income)/deductions–net, as well as charges related to the exit of certain sites, included in Restructuring charges and certain acquisition and divestiture-related costs.

(b) Adjusted net income and its components and adjusted diluted EPS are defined as reported U.S. GAAP net income and its components and reported diluted EPS excluding purchase accounting adjustments, acquisition and divestiture-related costs and certain significant items. Adjusted cost of sales, adjusted SG&A expenses, adjusted R&D expenses, and adjusted interest expense and other (income)/deductions-net are income statement line items prepared on the same basis, and, therefore, components of the overall adjusted income measure. Despite the importance of these measures to management in goal setting and performance measurement, adjusted net income and its components and adjusted diluted EPS are non-GAAP financial measures that have no standardized meaning prescribed by U.S. GAAP and, therefore, have limits in their usefulness to investors. Because of the non-standardized definitions, adjusted net income and its components and adjusted diluted EPS (unlike U.S. GAAP net income and its components and diluted EPS) may not be comparable to the calculation of similar measures of other companies. Adjusted net income and its components and adjusted diluted EPS are presented solely to permit investors to more fully understand how management assesses performance. Adjusted net income and its components and adjusted diluted EPS are not, and should not be viewed as, substitutes for U.S. GAAP net income and its components and diluted EPS. (c) We do not provide a reconciliation of forward-looking non-GAAP adjusted net income operational results to the most directly comparable U.S. GAAP reported financial measure because we are unable to calculate with reasonable certainty the foreign exchange impact of unusual gains and losses, acquisition and divestiture-related expenses, potential future asset impairments and other certain significant items, without unreasonable effort. The foreign exchange impacts of these items are uncertain, depend on various factors, and could have a material impact on U.S. GAAP reported results for the guidance period. (d) Primarily includes certain nonrecurring costs related to acquisitions, divestitures and other charges. ZOETIS INC.
