Item 2.    Management’s Discussion and Analysis of Financial Condition and Results of Operations

Overview of our business

Zoetis is a global leader in the animal health industry, focused on the discovery, development, manufacture and commercialization of medicines, vaccines, diagnostic products and services, biodevices, genetic tests and precision animal health. With a legacy of nearly 75 years, we continue to pioneer ways to predict, prevent, detect, and treat animal illness, supporting those raising and caring for animals worldwide - from veterinarians and pet owners to livestock producers.

We manage our operations through two geographic operating segments: the United States (U.S.) and International. Within each of these operating segments, we offer diverse products for both companion animals and livestock customers in order to capitalize on local and regional trends and customer needs. See Notes to Condensed Consolidated Financial Statements — Note 16. Segment Information.

We directly market our products to veterinarians and livestock producers located in approximately 45 countries across North America, Europe, Africa, Asia, Australia and South America, and are a market leader in nearly all of the major regions in which we operate. In markets where we do not have a direct commercial presence, we generally contract with distributors that provide logistics and sales and marketing support for our products.

Our companion animal and livestock products are primarily available by prescription through a veterinarian. On a more limited basis, in certain markets, we sell certain products through retail and e-commerce outlets. We also market our products by advertising to veterinarians, pet owners and livestock producers.

We believe our investments in one of the industry’s largest sales organizations, including our extensive network of technical and veterinary operations specialists, our high-quality manufacturing and reliability of supply, and our long track record of developing products that meet customer needs, has led to enduring and valued relationships with our customers. Our research and development (R&D) efforts enable us to deliver innovative products to address unmet needs and evolve our product lines so that they remain relevant for our customers.

We have approximately 300 product lines that we sell in over 100 countries for the prediction, prevention, detection and treatment of diseases and conditions that affect various companion animal and livestock species. The diversity of our product portfolio and our global operations provides stability to our overall business.

A summary of our 2026 performance compared with the comparable 2025 period follows:

Our operating environment

For a description of our operating environment, including factors that could materially affect our business, financial condition, or future results, see "Our Operating Environment" in the MD&A of our 2025 Annual Report on Form 10-K. Set forth below are updates to certain of the factors disclosed in our 2025 Annual Report on Form 10-K.

Quarterly Variability of Financial Results

Our quarterly financial results are subject to variability related to a number of factors including, but not limited to: tariffs and other trade protection measures, the decline in global macroeconomic conditions, competitive dynamics, geopolitical tensions with and economic uncertainty in certain markets, inflation, global supply chain disruption and supply availability, variability in distributor inventory stocking levels including as a result of expected demand and promotional activities, weather patterns, herd management decisions, regulatory actions, disease outbreaks, product and geographic mix, timing of price increases and customer expectations related to the same, timing of investment decisions and operational and other changes made in connection with the change in accounting principle to eliminate the one-month financial reporting lag in 2026 for our subsidiaries operating outside the U.S.

Tariffs and Trade Protection Measures

Our business is subject to risks related to, among other factors, tariffs and other trade protection measures put in the place by the United States or other countries, as well as U.S. international trade relations, including those with China, Canada and the European Union. Starting in early 2025, the United States government announced additional tariffs on certain goods imported into the U.S. from numerous countries and multiple nations countered with reciprocal tariffs and other actions in response. While the final tariffs and other measures to be imposed, and their applicability to our business, remain uncertain, such actions may negatively impact demand and result in an increase in some product costs. We will continue to actively monitor the situation and evaluate actions that can be taken to moderate and/or minimize its effects. For further information regarding the impact of potential additional tariffs and trade protection measures on the Company, see Part I., Item 1A, Risk Factors in our 2025 Annual Report on Form 10-K.

Disease Outbreaks

Sales of our livestock products have in the past, and may in the future be, adversely affected by the outbreak of disease carried by animals. Outbreaks of disease may reduce regional or global sales of particular animal-derived food products or result in reduced exports of such products, either due to heightened export restrictions or import prohibitions, which may reduce demand for our products. Also, the outbreak of any highly contagious disease near our main production sites could require us to immediately halt production of our products at such sites or force us to incur substantial expenses in procuring raw materials or products elsewhere. Alternatively, sales of products that treat specific disease outbreaks may increase.

Foreign Exchange Rates

Significant portions of our revenue and costs are exposed to changes in foreign exchange rates. Our products are sold in more than 100 countries and, as a result, our revenue is influenced by changes in foreign exchange rates. For the three months ended March 31, 2026, approximately 47% of our revenue was denominated in foreign currencies. We seek to manage our foreign exchange risk, in part, through operational means, including managing same-currency revenue in relation to same-currency costs and same-currency assets in relation to same-currency liabilities. As we operate in multiple foreign currencies, including the Australian dollar, Brazilian real, British pound, Canadian dollar, Chinese renminbi, euro and other currencies, changes in those currencies relative to the U.S. dollar will impact our revenue, cost of goods and expenses, and consequently, net income. Exchange rate fluctuations may also have an impact beyond our reported financial results and directly impact operations. These fluctuations may affect the ability to buy and sell our goods and services between markets impacted by significant exchange rate variances. For the three months ended March 31, 2026, approximately 53% of our total revenue was in U.S. dollars. Our year-over-year total revenue growth was favorably impacted by approximately 4% from changes in foreign currency values relative to the U.S. dollar. For operations in highly inflationary economies, we translate monetary items at rates in effect at the balance sheet date, with translation adjustments recorded in Other (income)/deductions––net, and we translate non-monetary items at historical rates.

Non-GAAP financial measures

We report information in accordance with U.S. generally accepted accounting principles (GAAP). Management also measures performance using non-GAAP financial measures that may exclude certain amounts from the most directly comparable GAAP measure. Despite the importance of these measures to management in goal setting and performance measurement, non-GAAP financial measures have no standardized meaning prescribed by U.S. GAAP and, therefore, have limits in their usefulness to investors and may not be comparable to the calculation of similar measures of other companies. We present certain identified non-GAAP measures solely to provide investors with useful information to more fully understand how management assesses performance.

Operational Results

We believe that it is important to not only understand overall revenue and earnings results, but also “operational” results. Operational results is a non-GAAP financial measure defined as revenue or earnings results excluding the impact of foreign exchange. This measure provides information on the change in revenue and earnings as if foreign currency exchange rates had not changed between the current and prior periods to facilitate a period-to-period comparison. We believe this non-GAAP measure provides a useful comparison to previous periods for the company and investors, but should not be viewed as a substitute for U.S. GAAP reported results.

Adjusted Net Income and Adjusted Earnings Per Share

Adjusted net income and the corresponding adjusted earnings per share (EPS) are non-GAAP financial measures of performance used by management. We believe these financial measures are useful supplemental information to investors when considered together with our U.S. GAAP financial measures. We report adjusted net income to portray the results of our major operations, and the discovery, development, manufacture and commercialization of our products, prior to considering certain income statement elements. We define adjusted net income and adjusted EPS as net income attributable to Zoetis and EPS before the impact of purchase accounting adjustments, acquisition and divestiture-related costs and certain significant items.

We recognize that, as an internal measure of performance, the adjusted net income and adjusted EPS measures have limitations, and we do not restrict our performance management process solely to these metrics. A limitation of the adjusted net income and adjusted EPS measures is that they provide a view of our operations without including all events during a period, such as the effects of an acquisition, divestiture or amortization of purchased intangibles, and do not provide a comparable view of our performance to other companies. The adjusted net income and adjusted EPS measures are not, and should not be viewed as, a substitute for U.S. GAAP reported net income attributable to Zoetis and reported EPS. See Adjusted Net Income section below for more information.

Fiscal year alignment of international subsidiaries

Our consolidated financial statements are prepared in accordance with accounting principles generally accepted in the United States of America (U.S. GAAP). Historically our consolidated financial statements, which have a year-end of December 31, have reflected financial information of subsidiaries operating outside the U.S. (the “International Subsidiaries”) on a one-month financial reporting lag with a year-end of November 30.

Our operating environment

Industry

The animal health industry, which focuses on both companion animals and livestock, is a growing industry that impacts billions of people worldwide. The primary companion animal species are dogs, cats and horses. Factors influencing growth in demand for companion animal medicines, vaccines and diagnostics include:

•increasing pet owners’ commitment to the health and well-being of their pets;

•economic development and related increases in disposable income, particularly in many emerging markets;

•companion animals living longer;

•increasing medical treatment of companion animals; and

•advances in companion animal medicines, vaccines and diagnostics.

The primary livestock species are cattle (both beef and dairy), swine, poultry, fish and sheep. Livestock health and production are essential to meeting the growing demand for animal protein of a global population. Factors influencing growth in demand for livestock medicines and vaccines include:

•human population growth and increasing standards of living, particularly in many emerging markets;

33 |

Table of Contents

•increasing demand for improved nutrition, particularly animal protein;

•natural resource constraints, such as scarcity of arable land, fresh water and increased competition for cultivated land, resulting in fewer resources that will be available to meet an increasing demand for animal protein;

•increasing urbanization; and

•increased focus on food safety and food security.

The overall economic environment

In addition to industry-specific factors, we, like other businesses, face challenges related to global economic conditions, an economic downturn and high inflation. Growth in both the livestock and companion animal sectors is driven by overall economic development and related growth, particularly in many emerging markets. In the past, certain of our customers and suppliers have been affected directly by shortages in veterinary healthcare workers and economic downturns or inflation, which decreased the demand for our products and, in some cases, hindered our ability to collect amounts due from customers.

Industry sources have reported that pet owners indicated a preference for reducing spending on other aspects of their lifestyle, including entertainment, clothing and household goods, before reducing spending on pet healthcare. Similarly, the cost of medicines and vaccines to our livestock producer customers is small relative to other production costs, including feed, and the use of these products is intended to improve livestock producers’ economic outcomes. As a result, demand for our products has historically been more stable than demand for other production inputs. Each of these factors, plus our broad and innovative portfolio, contributes to our ability to incorporate inflationary challenges into our product pricing and mitigate the impact on our results. While these factors have mitigated the impact of prior downturns in the global economy, economic challenges, including an economic downturn and inflation, could increase cost sensitivity among our customers, which may result in reduced demand for our products, which could have a material adverse effect on our operating results and financial condition.

Competition

The animal health industry is highly competitive. Although our business is the largest based on revenue in the animal health industry (which includes medicines, vaccines and diagnostics), we face competition in the regions in which we operate. Principal methods of competition vary depending on the particular region, species, product category or individual product. Some of these methods include new product development, quality, price, service and promotion to veterinary professionals, pet owners and livestock producers. Our competitors include standalone animal health businesses and the animal health businesses of large pharmaceutical companies. In recent years, there has been an increase in consolidation in the animal health industry. There are also many start-up companies working in the animal health area. In addition to competition from established market participants, there could be new entrants to the animal health medicines, vaccines and diagnostics industry in the future. We also compete with companies that produce generic products, following our products’ loss of exclusivity in a given market. For example, Draxxin currently competes with generic products in key markets including the U.S., Europe, Canada, Mexico and Australia. Since 2021, the first year of generic competition, sales of Draxxin declined by 66% in the U.S., its largest market. For more information regarding the generic competition we expect to encounter as patents on certain of our key products expire, see Item 1. Business – Intellectual Property.

Manufacturing and supply

In order to sell our products, we must be able to produce and ship our products in sufficient quantities. Many of our products involve complex manufacturing processes and are sole-sourced from certain manufacturing sites. Minor deviations in our manufacturing or logistical processes, such as temperature excursions or improper package sealing, could result in delays, inventory shortages, unanticipated costs, product recalls, product liability and/or regulatory action. In addition, a number of factors could cause production interruptions that could result in launch delays, inventory shortages, recalls, unanticipated costs or issues with our supply agreements with third parties.

Our manufacturing network may be unable to meet the demand for our products or we may have excess capacity if demand for our products changes. The unpredictability of a product's regulatory or commercial success or failure, the lead time necessary to construct highly technical and complex manufacturing sites, and shifting customer demand increase the potential for capacity imbalances.

Perceptions of product quality, safety and reliability

We believe that animal health customers value high-quality manufacturing and reliability of supply. The importance of quality and safety concerns to pet owners, veterinarians and livestock producers also contributes to animal health brand loyalty, which often continues after the loss of patent-based and regulatory exclusivity. We depend on positive perceptions of the safety and quality of our products by our customers, veterinarians and end-users.

In addition, negative beliefs about animal health products generally could impact demand for our products. For example, the issue of the potential transfer of increased antibacterial resistance in bacteria from food-producing animals to human pathogens, and the causality of that transfer, continue to be the subject of global scientific and regulatory discussion. In some countries, this issue has led to government restrictions and bans on the use of specific antibacterials in some food-producing animals, regardless of the route of administration (in feed or injectable). In addition, consumer preferences in some markets have impacted the use of antibacterials in food producing animals. Such restrictions and consumer preferences in some cases may negatively impact sales of our antibacterial products, but in other instances may increase sales of our products that can be used as antibacterial alternatives. Our total revenue attributable to antibacterials for livestock was approximately $713 million for the year ended December 31, 2025.

Similarly, concerns regarding greenhouse gas emissions and other potential environmental impacts of livestock production have led to some consumers opting to limit or avoid consuming animal products. However, we believe the impact of this trend is limited as the livestock industry is still expected to continue to grow in order to feed a growing global population.

Product development initiatives

Our future success depends on both our existing products and our pipeline of new products, including new products that we may develop through joint ventures and products that we are able to obtain through license or acquisition. We believe we are an industry leader in animal health R&D, with a track record of generating new products and product lifecycle innovation, which is defined as R&D programs that leverage existing animal health products by adding new species or claims, achieving approvals in new markets or creating new reformulations, modifications and combinations. The majority of our R&D programs focus on new products. In addition to traditional medicines and vaccines, we develop products across additional categories to address the needs of veterinarians and producers to predict, prevent, detect and treat conditions in both companion animals and livestock, including products and services in diagnostics, genetics, precision animal health and digital and data analytics.

Changing distribution channels for companion animal products

In most markets, companion animal owners typically purchase their animal health products directly from veterinarians. However, in the U.S. and certain other markets, companion animal owners increasingly have the option to purchase animal health products from sources other than veterinarians, such as internet-based retailers, “big-box” retail stores or other over-the-counter distribution channels. We believe the ability of pet owners to purchase our products online and from retail stores may increase pet owner compliance and result in increased sales. However, over time, we may be unable to sustain our current margins due to the increased purchasing power of such retailers as compared to traditional veterinary practices.

In addition, this trend could negatively impact the sales of products we primarily sell through the veterinarian distribution channel, as any decrease in visits to veterinarians by companion animal owners could reduce our market share and sales of such products. A reduction in the number of pet owners who purchase our products directly from their veterinarian could also lead to increased use of generic alternatives to our products or the increased substitution of our products with other animal health products or human health products if such other products are deemed to be lower-cost alternatives.

Disease Outbreaks

Sales of our livestock products have in the past, and may in the future be, adversely affected by the outbreak of disease carried by animals. Outbreaks of disease may reduce regional or global sales of particular animal-derived food products or result in reduced exports of such products, either due to heightened export restrictions or import prohibitions, which may reduce demand for our products. Also, the outbreak of any highly contagious disease near our main production sites could require us to immediately halt production of our products at such sites or force us to incur substantial expenses in procuring raw materials or products elsewhere. Alternatively, sales of products that treat specific disease outbreaks may increase.

Foreign exchange rates

Significant portions of our revenue and costs are exposed to changes in foreign exchange rates. Our products are sold in more than 100 countries and, as a result, our revenue is influenced by changes in foreign exchange rates. For the year ended December 31, 2025, approximately 42% of our revenue was denominated in foreign currencies. We seek to manage our foreign exchange risk, in part, through operational means, including managing same-currency revenue in relation to same-currency costs and same-currency assets in relation to same-currency liabilities. As we operate in multiple foreign currencies, including the Australian dollar, Brazilian real, British pound, Canadian dollar, Chinese renminbi, euro and other currencies, changes in those currencies relative to the U.S. dollar will impact our revenue, cost of goods and expenses, and consequently, net income. Exchange rate fluctuations may also have an impact beyond our reported financial results and directly impact operations. These fluctuations may affect the ability to buy and sell our goods and services between markets impacted by significant exchange rate variances. For the year ended December 31, 2025, approximately 58% of our total revenue was in U.S. dollars. Our year-over-year total revenue growth was unfavorably impacted by 1% from changes in foreign currency values relative to the U.S. dollar.

Weather conditions, climate change and the availability of natural resources

The animal health industry and demand for many of our animal health products in a particular region are affected by weather conditions, as usage of our products follows varying weather patterns and weather-related pressures from pests, such as ticks. As a result, we may experience regional and seasonal fluctuations in our results of operations.

In addition, veterinary hospitals and practitioners depend on visits from and access to the animals under their care. Veterinarians’ patient volume and ability to operate could be adversely affected if they experience prolonged snow, ice or other severe weather conditions, particularly in regions not accustomed to sustained inclement weather. Furthermore, weather conditions, including excessive cold or heat, natural disasters and other events, could negatively impact our livestock customers by impairing the health or growth of their animals or the production or availability of feed, as well as disrupting their normal operations. For example, livestock producers depend on the availability of natural resources, including large supplies of fresh water. Their animals’ health and their ability to operate could be adversely affected if they experience a shortage of fresh water due to human population growth, climate change or floods, droughts or other weather conditions. In the event of adverse weather conditions, climate-change related impacts or a shortage of fresh water, veterinarians and livestock producers may purchase less of our products.

Adverse weather conditions, natural disasters and climate change may also impact the aquaculture business. Changes in water temperatures could affect the timing of reproduction and growth of various fish species, as well as trigger the outbreak of certain waterborne diseases.

Our strategic pillars

Our vision is to be the most trusted and valued animal health company, shaping the future of animal care through our innovation, customer obsession and purpose-driven colleagues. We have a global presence in both developed and emerging markets and across eight core species. We intend to grow our business by pursuing the following core strategies:

Components of revenue and costs and expenses

Our revenue, costs and expenses are reported for the year ended December 31 for each year presented, except for subsidiaries operating outside the U.S., for which the financial information is included in our consolidated financial statements for the fiscal year ended November 30 for each year presented.

Revenue

Our revenue is primarily derived from our diversified product portfolio of medicines, vaccines and diagnostic products and services used to treat and protect companion animals and livestock. Generally, our products are promoted to veterinarians and livestock producers by our sales organization which includes sales representatives and technical and veterinary operations specialists, and then sold directly by us or through distributors, retailers or e-commerce outlets. The depth of our product portfolio enables us to address the varying needs of customers in different species and geographies. In 2025, our two top-selling products and product lines, Simparica/Simparica Trio and Apoquel/Apoquel Chewable, contributed approximately 16% and 12% of our revenue, respectively, and combined with our next three top-selling products and product lines, Cytopoint, Librela and our ceftiofur line, these five products and product lines contributed approximately 42% of our revenue. Our ten top-selling products and product lines contributed 57% of our revenue. For additional information regarding our products, including descriptions of our product lines that each represented approximately 1% or more of our revenue in 2025, see Item 1. Business—Products.

Costs and expenses

Costs of sales consist primarily of cost of materials, facilities and other infrastructure used to manufacture our medicine and vaccine products, as well as costs to operate our reference labs and royalty expenses associated with the intellectual property of our products, when relevant.

Selling, general and administrative (SG&A) expenses consist of, among other things, the internal and external costs of marketing, promotion, advertising and shipping and handling as well as certain costs related to business technology, facilities, legal, finance, human resources, business development, public affairs and procurement.

Research and development (R&D) expenses consist primarily of project costs specific to new product R&D and product lifecycle innovation, overhead costs associated with R&D operations and investments that support local market clinical trials for approved indications and expenses related to regulatory approvals for our products. We do not disaggregate R&D expenses by research stage or by therapeutic area for purposes of managing our business.

Amortization of intangible assets consists primarily of the amortization expense for identifiable finite-lived intangible assets that have been acquired through business combinations. These assets consist of, but are not limited to, developed technology, brands and trademarks.

Restructuring charges and certain acquisition and divestiture-related costs consist of all restructuring charges (those associated with cost reduction/productivity initiatives and those associated with acquisition activity) and costs associated with executing the transaction which include acquiring and integrating businesses and costs associated with divesting and disintegrating businesses. Restructuring charges are associated with employees, assets and activities that will not continue in the company. Acquisition and divestiture-related costs are associated with acquiring and integrating acquired businesses, which may include expenditures for consulting and the integration of systems and processes, product transfers, transaction costs and restructuring the company, as well as costs associated with divesting and disintegrating a portion of our business which may include expenditures for consulting and the disintegration of systems and processes, transfer costs, and restructuring charges which may include charges related to employees, assets and activities that will not continue in the company's ongoing operations.

Other (income)/deductions—net consists of various items, primarily net (gains)/losses on business sales and divestitures, as well as asset disposals, interest income, royalty-related income, foreign exchange translation (gains)/losses and certain asset impairment charges.

Variability of Financial Results

Our financial results are subject to variability related to a number of factors including, but not limited to: tariffs and other trade protection measures, the decline in global macroeconomic conditions, competitive dynamics, geopolitical tensions with and economic uncertainty in certain markets, inflation, global supply chain disruption and supply availability, variability in distributor inventory stocking levels, including as a result of expected demand and promotional activities, weather patterns, herd management decisions, regulatory actions, disease outbreaks, product and geographic mix, timing of price increases and customer expectations related to the same, timing of investment decisions and operational and other changes made in connection with the expected change in accounting principle to eliminate the one-month reporting lag in 2026 for our subsidiaries operating outside the U.S.

Significant accounting policies and application of critical accounting estimates

In presenting our financial statements in conformity with U.S. GAAP, we are required to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenue, costs and expenses and related disclosures. For a description of our significant accounting policies, see Notes to Consolidated Financial Statements—Note 3. Significant Accounting Policies.

We believe that the following accounting policies are critical to an understanding of our consolidated financial statements as they require the application of the most difficult, subjective and complex judgments and, therefore, could have the greatest impact on our financial statements: (i) fair value; (ii) revenue; (iii) asset impairment reviews; and (iv) contingencies.

Below are some of our more critical accounting estimates. See Notes to Consolidated Financial Statements—Note 3. Significant Accounting Policies: Estimates and Assumptions for a discussion about the risks associated with estimates and assumptions.

Fair value

For a discussion about the application of fair value to our long-term debt and financial instruments, see Notes to Consolidated Financial Statements—Note 9. Financial Instruments.

For a discussion about the application of fair value to our business combinations, see Notes to Consolidated Financial Statements—Note 3. Significant Accounting Policies: Fair Value.

For a discussion about the application of fair value to our asset impairment reviews, see Asset impairment reviews below.

Revenue

Our gross product revenue is subject to deductions that are generally estimated and recorded in the same period that the revenue is recognized and primarily represents sales returns and revenue incentives. For example:

•for sales returns, we perform calculations in each market that incorporate the following, as appropriate: local returns policies and practices; past returns as a percentage of revenue; an understanding of the reasons for past returns; estimated shelf life by product; an estimate of the amount of time between shipment and return or lag time; and any other factors that could impact the estimate of future returns, product recalls, discontinuation of products or a changing competitive environment; and

•for revenue incentives, we use our historical experience with similar incentives programs to estimate the impact of such programs on revenue.

If any of our ratios, factors, assessments, experiences or judgments are not indicative or accurate predictors of our future experience, our results could be materially affected. Although the amounts recorded for these revenue deductions are dependent on estimates and assumptions, historically our adjustments to actual results have not been material. The sensitivity of our estimates can vary by program, type of customer and geographic location.

Amounts recorded for revenue deductions can result from a complex series of judgments about future events and uncertainties and can rely on estimates and assumptions. For further information about the risks associated with estimates and assumptions, see Notes to Consolidated Financial Statements—Note 3. Significant Accounting Policies: Estimates and Assumptions.

Asset impairment reviews

We review all of our long-lived assets for impairment indicators throughout the year and we perform detailed testing whenever impairment indicators are present. In addition, we perform impairment testing for goodwill and indefinite-lived intangible assets at least annually. When necessary, we record charges for impairments of long-lived assets for the amount by which the fair value is less than the carrying value of these assets.

Our impairment review processes are described below and in Notes to Consolidated Financial Statements—Note 3. Significant Accounting Policies: Amortization of Intangible Assets, Depreciation and Certain Long-Lived Assets and, for deferred tax assets, in Note 3. Significant Accounting Policies: Deferred Tax Assets and Liabilities and Income Tax Contingencies.

Examples of events or circumstances that may be indicative of impairment include:

•a significant adverse change in the extent or manner in which an asset is used. For example, restrictions imposed by the regulatory authorities could affect our ability to manufacture or sell a product; and

•a projection or forecast that demonstrates losses or reduced profits associated with an asset. This could result, for example, from the introduction of a competitor’s product that results in a significant loss of market share or the inability to achieve the previously projected revenue growth, or from the lack of acceptance of a product by customers.

For finite-lived identifiable intangible assets, such as developed technology rights, and for other long-lived assets, such as property, plant and equipment, whenever impairment indicators are present, we calculate the undiscounted value of the projected cash flows associated with the asset, or asset group, and compare this estimated amount to the carrying amount. If the carrying amount is found to be greater, we record an impairment loss for the excess of book value over fair value. In addition, in all cases of an impairment review, we re-evaluate the remaining useful lives of the assets and modify them, as appropriate.

37 |

Table of Contents

Our impairment reviews of most of our long-lived assets depend on the determination of fair value, as defined by U.S. GAAP. A single estimate of fair value can result from a complex series of judgments about future events and uncertainties and can rely on estimates and assumptions which can materially impact our results of operations. For information about the risks associated with estimates and assumptions, see Notes to Consolidated Financial Statements—Note 3. Significant Accounting Policies: Estimates and Assumptions.

Intangible assets other than goodwill

We test indefinite-lived intangible assets for impairment at least annually, or more frequently if impairment indicators exist, by first assessing qualitative factors to determine whether it is more likely than not that the fair value of the indefinite-lived intangible asset is less than its carrying amount. If we conclude it is more likely than not that the fair value is less than the carrying amount, a quantitative test that compares the fair value of the indefinite-lived intangible asset with its carrying value is performed. If the fair value is less than the carrying amount, an impairment loss is recognized. Impairments of identifiable intangible assets other than goodwill, are recorded in Restructuring charges and certain acquisition and divestiture-related costs and Other (income)/deductions—net, as applicable. We did not have any material intangible asset impairment charges for the years ended December 31, 2025, 2024 and 2023.

When we are required to determine the fair value of intangible assets other than goodwill, we use an income approach, specifically the multi-period excess earnings method, also known as the discounted cash flow method. We start with a forecast of all the expected net cash flows associated with the asset, which includes the application of a terminal value for indefinite-lived assets, and then we apply an asset-specific discount rate to arrive at a net present value amount. Some of the more significant estimates and assumptions inherent in this approach include: the amount and timing of the projected net cash flows, which includes the expected impact of competitive, legal and/or regulatory forces on the projections, the impact of technological risk associated with IPR&D assets, as well as the selection of a long-term growth rate; the discount rate, which seeks to reflect the risks inherent in the projected cash flows; foreign currency fluctuations; and the effective tax rate, which seeks to incorporate the geographic diversity of the projected cash flows.

While all identifiable intangible assets can be impacted by events and thus lead to impairment, in general, identifiable intangible assets that are at the highest risk of impairment include IPR&D assets ($141 million as of December 31, 2025). IPR&D assets are higher-risk assets given the uncertain nature of R&D activity.

For a description of our accounting policy, see Notes to Consolidated Financial Statements—Note 3. Significant Accounting Policies: Amortization of Intangible Assets, Depreciation and Certain Long-Lived Assets.

Goodwill

Goodwill represents the excess of the consideration transferred over the fair value of net assets of businesses purchased and is assigned to reporting units. We test goodwill for impairment on at least an annual basis, or more frequently if necessary, either by assessing qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount or by performing a periodic quantitative assessment.

Factors considered in the qualitative assessment include general macroeconomic conditions, conditions specific to the industry and market, cost factors which could have a significant effect on earnings or cash flows, the overall financial performance of the reporting unit and whether there have been sustained declines in our share price. Additionally, we evaluate the extent to which the fair value exceeded the carrying value of the reporting unit at the date of the last quantitative assessment performed.

When performing a quantitative assessment to test for goodwill impairment we utilize the income approach, which is forward-looking, and relies primarily on internal forecasts. Within the income approach, the method that we use is the discounted cash flow method. We start with a forecast of all the expected net cash flows associated with the reporting unit, which includes the application of a terminal value, and then apply a reporting unit-specific discount rate to arrive at a net present value. Some of the more significant estimates and assumptions inherent in this approach include: the amount and timing of the projected net cash flows, which includes the expected impact of technological risk and competitive, legal and/or regulatory forces on the projections, as well as the selection of a long-term growth rate; the discount rate, which seeks to reflect the various risks inherent in the projected cash flows; and the effective tax rate, which seeks to incorporate the geographic diversity of the projected cash flows.

We test goodwill for impairment on at least an annual basis, or more frequently if necessary, either by assessing qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount or by performing a periodic quantitative assessment. In 2025, we performed a periodic qualitative impairment assessment as of September 30, 2025 and, in 2024, we performed a quantitative impairment assessment as of September 30, 2024, which did not result in the impairment of goodwill associated with any of our reporting units in either period.

For all of our reporting units, there are a number of future events and factors that may impact future results and that could potentially have an impact on the outcome of subsequent goodwill impairment testing. For a list of these factors, see Forward-looking statements and factors that may affect future results.

For a description of our accounting policy, see Notes to Consolidated Financial Statements—Note 3. Significant Accounting Policies: Amortization of Intangible Assets, Depreciation and Certain Long-Lived Assets.

Contingencies

For a discussion about income tax contingencies, see Notes to Consolidated Financial Statements—Note 8C. Tax Matters: Tax Contingencies.

For a discussion about legal contingencies, guarantees and indemnifications, see Notes to Consolidated Financial Statement—Note 18. Commitments and Contingencies.

Non-GAAP financial measures

We report information in accordance with U.S. generally accepted accounting principles (GAAP). Management also measures performance using non-GAAP financial measures that may exclude certain amounts from the most directly comparable GAAP measure. Despite the importance of these

38 |

Table of Contents

measures to management in goal setting and performance measurement, non-GAAP financial measures have no standardized meaning prescribed by U.S. GAAP and, therefore, have limits in their usefulness to investors and may not be comparable to the calculation of similar measures of other companies. We present certain identified non-GAAP measures solely to provide investors with useful information to more fully understand how management assesses performance.

Operational Growth

We believe that it is important to not only understand overall revenue and earnings growth, but also “operational growth.” Operational growth is a non-GAAP financial measure defined as revenue or earnings growth excluding the impact of foreign exchange. This measure provides information on the change in revenue and earnings as if foreign currency exchange rates had not changed between the current and prior periods to facilitate a period-to-period comparison. We believe this non-GAAP measure provides a useful comparison to previous periods for the company and investors, but should not be viewed as a substitute for U.S. GAAP reported growth.

Adjusted Net Income and Adjusted Earnings Per Share

Adjusted net income and the corresponding adjusted earnings per share (EPS) are non-GAAP financial measures of performance used by management. We believe these financial measures are useful supplemental information to investors when considered together with our U.S. GAAP financial measures. We report adjusted net income to portray the results of our major operations, and the discovery, development, manufacture and commercialization of our products, prior to considering certain income statement elements. We define adjusted net income and adjusted EPS as net income attributable to Zoetis and EPS before the impact of purchase accounting adjustments, acquisition and divestiture-related costs and certain significant items.

We recognize that, as an internal measure of performance, the adjusted net income and adjusted EPS measures have limitations, and we do not restrict our performance management process solely to these metrics. A limitation of the adjusted net income and adjusted EPS measures is that they provide a view of our operations without including all events during a period, such as the effects of an acquisition or amortization of purchased intangibles, and do not provide a comparable view of our performance to other companies. The adjusted net income and adjusted EPS measures are not, and should not be viewed as, a substitute for U.S. GAAP reported net income attributable to Zoetis and reported EPS. See the Adjusted Net Income section below for more information.

Fiscal Year Alignment of International Subsidiaries

Our consolidated financial statements are prepared in accordance with accounting principles generally accepted in the United States of America (U.S. GAAP). For subsidiaries operating outside the U.S. (the “International Subsidiaries”), the consolidated financial information is included as of and for the fiscal year ended November 30 for each year presented. As a result, results of operations of our International Subsidiaries for the month of December 2025 are not included in our consolidated results of operations for fiscal year 2025 (and results of operations of our International Subsidiaries for the month of December 2024 are included).

In connection with our multi-year process to transition our ERP system noted above, we expect to eliminate the one-month reporting lag in 2026 for our International Subsidiaries, effective beginning with the Company’s first quarterly report in 2026, which would result in an alignment of the year-end for all subsidiaries and operations to December 31 (the “Expected Fiscal Year Alignment”). As a result of this alignment, the results of operations of our International Subsidiaries for the month of December 2025 would not be included in our consolidated results of operations for fiscal year 2026 but will be included in the retrospective application of the new accounting principle to prior financial statement periods. This alignment is an important preliminary step in the process to transition our ERP system because it will contribute to more seamless financial consolidation, regulatory compliance and consistent reporting.

In connection with the Expected Fiscal Year Alignment, revenue in the International segment for the reported fourth quarter of 2025 benefited from operational changes resulting in the acceleration of the timing of sales into the reported fourth quarter of 2025, which led to an approximate 2.5% to 3.5% increase in sales in the International segment in the reported fourth quarter of 2025, a trend that we do not expect to recur at the end of fiscal year 2026.

The operational changes in connection with the Expected Fiscal Year Alignment to date also included a shift implemented in early 2026 to the timing of annual price increases in certain International Subsidiaries so that the price increase and anticipated customer buying preceding the price increase would occur in the same calendar year. In addition, processing of certain customer orders from December 2025 was delayed to calendar year 2026.

2025 vs. 2024

Total revenue increased by $211 million, or 2%, in 2025 compared with 2024 reflecting operational revenue growth of $247 million, or 3%. Operational revenue growth was primarily due to the following:

•price growth of approximately 4%;

•volume growth from other in-line products of approximately 1%; and

•volume growth from key franchises of approximately 1%,

partially offset by:

•volume decrease related to the impact of the divestiture of our medicated feed additive product portfolio, certain water soluble products and related assets (MFA divestiture) of approximately 3%.

Foreign exchange decreased our reported revenue growth by approximately $36 million, or 1%.

2025 vs. 2024

Restructuring charges and certain acquisition and divestiture-related costs were $51 million in 2025 and $53 million in 2024. Restructuring charges and certain acquisition and divestiture-related costs in 2025 primarily consisted of charges related to a transition from internal to external innovation and manufacturing of certain products and the closure of a related site, as well as employee termination costs related to organizational structure refinements. Restructuring charges and certain acquisition and divestiture-related costs in 2024 primarily consisted of employee termination costs related to organizational structure refinements, as well as costs related to the sale of our medicated feed additive product portfolio, certain water soluble products and related assets, partially offset by a reversal of certain employee termination costs as a result of a change in strategy from our 2015 operational efficiency initiative.

The income tax provision in the Consolidated Statements of Income includes tax costs and benefits, such as uncertain tax positions, repatriation decisions and audit settlements, among others.

2025 vs. 2024

Our effective tax rate was 20.4% for 2025 and 20.3% for 2024. The higher effective tax rate for 2025, as compared to 2024, was primarily attributable to a lower benefit in the U.S. related to foreign-derived intangible income, partially offset by a more favorable jurisdictional mix of earnings (which includes the impact of the location of pre-tax earnings, tax impact of permanent differences and repatriation activity) and higher net discrete tax benefits.

2025 vs. 2024

U.S. operating segment

U.S. segment revenue increased by $23 million in 2025, which was relatively flat compared with 2024, of which $166 million resulted from growth in companion animal products, partially offset by a $143 million decline in livestock products.

•Companion animal revenue growth was primarily due to increased sales of Simparica Trio, key dermatology products and small animal diagnostics, partially offset by lower sales of Librela.

•Livestock revenue declined due to the impact of the MFA divestiture across cattle, poultry and swine products. Excluding the impact of the MFA divestiture, livestock revenue increased primarily due to higher demand for vaccines in our cattle and poultry markets, partially offset by a decrease in demand for certain swine products.

U.S. segment earnings increased by $102 million, or 3%, in 2025 compared with 2024, primarily due to higher revenue and lower cost of sales, partially offset by higher operating expenses.

International operating segment

International segment revenue increased by $152 million, or 4%, in 2025 compared with 2024. Operational revenue growth was $188 million, or 5%, reflecting growth of $145 million in companion animal products and $43 million in livestock products.

•Companion animal operational revenue growth was driven primarily by increased sales of our Simparica franchise products, key dermatology products and our mAb products for OA pain, Librela and Solensia.

43 |

Table of Contents

•Livestock operational revenue growth was due to increased sales in our cattle and fish products, partially offset by lower sales of poultry products. Excluding the impact of the MFA divestiture, livestock revenue increased across all species. Sales of cattle products grew largely due to price and sales of poultry products grew due to higher demand for vaccines in key poultry markets and price. Sales of our fish products grew due to increased vaccine sales in Norway and Chile. Sales of swine products increased due to higher demand for vaccines and geographic expansion.

•International segment revenue was positively impacted by operational changes made in connection with the Expected Fiscal Year Alignment, leading to an approximate 2.5% to 3.5% increase in sales in the International segment in the reported fourth quarter 2025 due to an acceleration of the timing of sales into the reported fourth quarter of 2025, a trend that we do not expect to recur.

•Additionally, International segment revenue was unfavorably impacted by foreign exchange which decreased revenue by approximately $36 million, or 1%, primarily driven by the Brazilian real, Argentinian peso, Turkish lira, Mexican peso, Australian dollar and Canadian dollar.

International segment earnings increased by $146 million, or 7%, in 2025 compared with 2024. Operational earnings growth was $106 million, or 5%, primarily due to higher revenue, partially offset by higher cost of sales and operating expenses.

Other business activities

Other business activities includes our Client Supply Services contract manufacturing results, our human health business and expenses associated with our dedicated veterinary medicine research and development organization, research alliances, U.S. regulatory affairs and other operations focused on the development of our products. Other R&D-related costs associated with non-U.S. market and regulatory activities are generally included in the International segment.

2025 vs. 2024

Other business activities net loss was flat in 2025 compared with 2024, reflecting a decrease in R&D costs primarily due to timing of spend related to projects and other strategic investments, as well as contract manufacturing results, offset by an increase in certain compensation-related costs and depreciation expense.

Reconciling items

Reconciling items include certain costs that are not allocated to our operating segments results, such as costs associated with the following:

•Corporate, which includes certain costs associated with information technology, facilities, legal, finance, human resources, business development, certain diagnostics costs and communications, among others. These costs also include certain compensation costs, certain procurement costs, and other miscellaneous operating expenses that are not charged to our operating segments, as well as interest income and expense;

•Certain transactions and events such as Purchase accounting adjustments, Acquisition and divestiture-related activities and Certain significant items, which are defined below; and

•Other unallocated, which includes (i) certain overhead expenses associated with our global manufacturing operations not charged to our operating segments; (ii) certain costs associated with finance that specifically support our global manufacturing operations; (iii) certain supply chain and global logistics costs; and (iv) certain procurement costs.

2025 vs. 2024

Corporate expenses increased by $27 million, or 2%, in 2025 compared with 2024, primarily due to an increase in compensation-related costs, partially offset by favorable foreign exchange.

Other unallocated expenses increased by $19 million, or 6%, in 2025 compared with 2024, primarily due to higher manufacturing costs and other charges, partially offset by lower inventory obsolescence, freight charges and favorable foreign exchange.

Adjusted net income

General description of adjusted net income (a non-GAAP financial measure)

Adjusted net income is an alternative view of performance used by management, and we believe that investors’ understanding of our performance is enhanced by disclosing this performance measure. The adjusted net income measure is an important internal measurement for us. Additionally, we measure our overall performance on this basis in conjunction with other performance metrics. The following are examples of how the adjusted net income measure is utilized:

•senior management receives a monthly analysis of our operating results that is prepared on an adjusted net income basis;

•our annual budgets are prepared on an adjusted net income basis; and

•other goal setting and performance measurements.

Purchase accounting adjustments

Adjusted net income is calculated prior to considering certain significant purchase accounting impacts that result from business combinations and net asset acquisitions. These impacts, primarily associated with certain acquisitions, include amortization related to the increase in fair value of the acquired finite-lived intangible assets and depreciation related to the increase/decrease to fair value of the acquired fixed assets. Therefore, the adjusted net income measure includes the revenue earned upon the sale of the acquired products without considering the aforementioned significant charges.

While certain purchase accounting adjustments can occur through 20 or more years, this presentation provides an alternative view of our performance that is used by management to internally assess business performance. We believe the elimination of amortization attributable to acquired intangible

44 |

Table of Contents

assets provides management and investors an alternative view of our business results by providing a degree of parity to internally developed intangible assets for which R&D costs previously have been expensed.

A completely accurate comparison of internally developed intangible assets and acquired intangible assets cannot be achieved through adjusted net income. These components of adjusted net income are derived solely from the impact of the items listed above. We have not factored in the impact of any other differences in experience that might have occurred if we had discovered and developed those intangible assets on our own, and this approach does not intend to be representative of the results that would have occurred in those circumstances. For example, our R&D costs in total, and in the periods presented, may have been different; our speed to commercialization and resulting revenue, if any, may have been different; or our costs to manufacture may have been different. In addition, our marketing efforts may have been received differently by our customers. As such, in total, there can be no assurance that our adjusted net income amounts would have been the same as presented had we discovered and developed the acquired intangible assets.

Acquisition and divestiture-related costs

Adjusted net income is calculated prior to considering transaction, integration and disintegration costs associated with significant business combinations, net asset acquisitions and divestitures. These incremental costs are excluded as they are incurred to acquire and integrate, or dispose and disintegrate, certain businesses as a result of the acquisition or disposal decision and are unique to each transaction. We have made no adjustments for the resulting synergies from these transactions.

We believe that viewing income prior to considering these charges provides investors with a useful additional perspective because the significant costs incurred in a business combination, net asset acquisition or divestiture result primarily from the need to eliminate duplicate assets, activities or employees––a natural result of acquiring or disposing of a fully integrated set of activities. For this reason, we believe that the costs incurred to convert disparate systems, to close duplicative facilities or to eliminate duplicate positions (for example, in the context of a business combination) can be viewed differently from those costs incurred in the ordinary course of business.

The integration and disintegration costs associated with a business combination, asset acquisition or divestiture may occur over several years, with the more significant impacts generally ending within three years of the transaction. Because of the need for certain external approvals for some actions, the span of time needed to achieve certain restructuring and integration or disintegration activities can be lengthy. For example, due to the regulated nature of the animal health medicines, vaccines and diagnostic business, the closure of excess facilities can take several years, as all manufacturing changes are subject to extensive validation and testing and must be approved by the U.S. Food and Drug Administration and/or other regulatory authorities.

Certain significant items

Adjusted net income is calculated excluding certain significant items. Certain significant items represent substantive, unusual items that are evaluated on an individual basis. Such evaluation considers both the quantitative and the qualitative aspect of their unusual nature. Unusual, in this context, may represent items that are not part of our ongoing business; items that, either as a result of their nature or size, we would not expect to occur as part of our normal business on a regular basis; items that would be nonrecurring; or items that relate to products that we no longer sell. While not all-inclusive, examples of items that could be included as certain significant items would be costs related to a major non-acquisition or divestiture-related restructuring charge and associated implementation costs for a program that is specific in nature with a defined term, such as those related to our non-acquisition or divestiture-related cost-reduction and productivity initiatives; costs related to our business process transformation program; amounts related to disposals of products or facilities that do not qualify as discontinued operations as defined by U.S. GAAP; certain asset impairment charges; adjustments related to the resolution of certain tax positions; significant currency devaluation; the impact of adopting certain significant, event-driven tax legislation; or charges related to legal matters. See Notes to Consolidated Financial Statements— Note 18. Commitments and Contingencies. Our normal, ongoing defense costs or settlements of and accruals on legal matters made in the normal course of our business would not be considered certain significant items.

The higher effective tax rate on adjusted pretax income for 2025, as compared to 2024, was primarily attributable to a lower benefit in the U.S related to foreign-derived intangible income and a less favorable jurisdictional mix of earnings (which includes the impact of the location of pre-tax earnings, tax impact of permanent differences and repatriation activity), partially offset by higher net discrete benefits.

The lower effective tax rate on adjusted pretax income for 2024, as compared to 2023, was primarily attributable to a higher benefit in the U.S. related to foreign-derived intangible income and lower net discrete tax expenses, partially offset by a less favorable jurisdictional mix of earnings (which includes the impact of the location of earnings, repatriation costs and Pillar Two global minimum tax). Jurisdictional mix of earnings can vary depending on repatriation decisions, operating fluctuations in the normal course of business and the impact of non-deductible and non-taxable items.

Analysis of the Consolidated Statements of Comprehensive Income

Changes in other comprehensive income for the periods presented are primarily related to foreign currency translation adjustments and unrealized gains/(losses) on derivative instruments. The foreign currency translation adjustment changes result from the strengthening or weakening of the U.S. dollar as compared to the currencies in the countries in which we do business. Unrealized gains/(losses) on the changes in the fair value of derivative instruments are recorded within Accumulated other comprehensive income/(loss) and reclassified into earnings depending on the nature and purpose of the financial instrument, as described in Note 9.

Analysis of the Consolidated Balance Sheets

December 31, 2025 vs. December 31, 2024

For a discussion about the changes in Cash and cash equivalents, Short-term borrowings, Current portion of long-term debt and Long-term debt, net of discount and issuance costs, see “Analysis of financial condition, liquidity and capital resources” below.

Accounts receivable, less allowance for doubtful accounts increased primarily as a result of higher net sales in the period.

Inventories increased primarily as a result of inventory build-up to support production for the forecasted demand of certain products. See Notes to Consolidated Financial Statements - Note 11. Inventories.

Other current assets increased primarily due to an increase in collateral posted related to derivative contracts, the deferral of a prepaid tax benefit in connection with a prepayment from a related foreign entity in Belgium, as well as higher value-added tax receivables, partially offset by the mark-to-market adjustments of derivative instruments.

Property, plant and equipment less accumulated depreciation increased primarily as a result of capital spending, partially offset by depreciation expense. See Notes to Consolidated Financial Statements - Note 12. Property, Plant and Equipment.

The increase in Operating lease right-of-use assets reflects assets acquired through new and amended lease agreements, partially offset by lease amortization, while the increase in Operating lease liabilities primarily reflects an amended lease obligation in the current period, partially offset by lease payments. See Notes to Consolidated Financial Statements—Note 10. Leases.

Identifiable intangible assets, less accumulated amortization decreased primarily due to amortization expense. See Notes to Consolidated Financial Statements - Note 13. Goodwill and Other Intangible Assets.

The net changes in Noncurrent deferred tax assets, Noncurrent deferred tax liabilities, Income taxes payable and Other taxes payable primarily reflect adjustments to the accrual for the income tax provision, the timing of income tax payments and the tax impact of various acquisitions and divestitures.

Other noncurrent assets increased primarily due to capitalized cloud computing arrangements implementation costs, partially offset by the mark-to-market adjustments of derivative instruments.

Accounts payable increased as a result of the timing of vendor and value-added tax payments.

Accrued expenses increased primarily as a result of increases in accrued contract rebates, interest and third-party inventory.

Accrued compensation and related items decreased primarily due to the payments of 2024 annual incentive bonuses, payments for sales incentive bonuses and savings plan contributions to eligible employees, partially offset by the accrual of 2025 annual incentive bonuses, savings plan contributions to eligible employees and sales incentive bonuses.

Other current liabilities decreased primarily due to a decrease in collateral received related to derivative contracts, partially offset by the mark-to-market adjustments of derivative instruments.

Other noncurrent liabilities increased primarily due to the mark-to-market adjustments of derivative instruments.

2025 vs. 2024

Net cash provided by operating activities was $2,904 million in 2025 compared with $2,953 million in 2024. The decrease in operating cash flows was primarily attributable to the timing of receipts and payments in the ordinary course of business and higher inventory build-up of certain products due to increased demand, partially offset by higher net income adjusted by non-cash items and the timing of income taxes paid.

Investing activities

2025 vs. 2024

Net cash used in investing activities was $748 million in 2025 compared with $315 million in 2024. The net cash used in investing activities for 2025 was primarily due to capital expenditures and net payments of derivative instrument activity. The net cash used in investing activities for 2024 was primarily due to capital expenditures, partially offset by net proceeds on the sale of our medicated feed additive product portfolio, certain water soluble products and related assets, as well as net proceeds from derivative instrument activity.

Financing activities

2025 vs. 2024

Net cash used in financing activities was $1,870 million in 2025 compared with $2,660 million in 2024. The net cash used in financing activities for 2025 was primarily attributable to the purchase of treasury shares and related excise taxes, the repayment of the aggregate principal amounts of our 2015 and 2022 senior notes due 2025, the payment of dividends and payment of the capped calls related to the convertible senior notes, partially offset by proceeds from the issuance of the convertible senior notes in December 2025 and senior notes in August 2025. The net cash used in financing activities for 2024 was primarily attributable to the purchase of treasury shares and related payment of excise taxes, the payment of dividends and taxes paid on withholding shares, partially offset by proceeds in connection with the issuance of common stock under our equity incentive plan.

Analysis of financial condition, liquidity and capital resources

While we believe our cash and cash equivalents on hand, our operating cash flows and our existing financing arrangements will be sufficient to support our cash needs for the next twelve months and beyond, this may be subject to the environment in which we operate. Risks to our meeting future funding requirements are described in Global economic conditions below.

For the years ended December 31, 2025 and 2024, the number of days that accounts receivables were outstanding have remained within this range. We regularly monitor our accounts receivable for collectability, particularly in markets where economic conditions remain uncertain. We believe that our allowance for doubtful accounts is appropriate. Our assessment is based on such factors as past due aging, historical and expected collection patterns, the financial condition of our customers, the robust nature of our credit and collection practices and the economic environment.

Credit facility and other lines of credit

In August 2025, we entered into a new revolving credit agreement with a syndicate of banks providing for a multi-year $1.25 billion senior unsecured revolving credit facility (the credit facility), which expires in August 2030. Subject to certain conditions, we have the right to increase the credit facility up to $1.75 billion. The credit facility contains a financial covenant requiring us to not exceed a maximum total leverage ratio (the ratio of consolidated net debt as of the end of the period to consolidated Earnings Before Interest, Income Taxes, Depreciation and Amortization (EBITDA) for such period) of 3.50:1. Upon entering into a material acquisition, the maximum total leverage ratio increases to 4.00:1, and extends until the fourth full consecutive fiscal quarter ended immediately following the consummation of a material acquisition. In addition, the credit facility contains other customary covenants.

We were in compliance with all financial covenants as of December 31, 2025 and December 31, 2024. There were no amounts drawn under the credit facility as of December 31, 2025 or December 31, 2024.

We have additional lines of credit and other credit arrangements with a group of banks and other financial intermediaries for general corporate purposes. We maintain cash and cash equivalent balances in excess of our outstanding short-term borrowings. As of December 31, 2025, we had access to $51 million of lines of credit which expire at various times and are generally renewed annually. There were no borrowings outstanding related to these facilities as of December 31, 2025 or December 31, 2024.

Domestic and international short-term funds

Many of our operations are conducted outside the U.S. The amount of funds held in the U.S. will fluctuate due to the timing of receipts and payments in the ordinary course of business and due to other reasons, such as business development activities. As part of our ongoing liquidity assessments, we regularly monitor the mix of U.S. and international cash flows (both inflows and outflows). Actual repatriation of overseas funds can result in additional U.S. and local income taxes, such as U.S. state income taxes, local withholding taxes, and taxes on currency gains and losses. See Notes to Consolidated Financial Statements—Note 8. Tax Matters.

Global economic conditions

Global financial markets may be impacted by macroeconomic, business and financial volatility. Challenging economic conditions in recent years have not had, nor do we anticipate that it will have, a significant impact on our liquidity. Due to our operating cash flows, financial assets, access to capital markets and available lines of credit and revolving credit agreements, we continue to believe that we have the ability to meet our liquidity needs for the foreseeable future. As markets change, we continue to monitor our liquidity position. There can be no assurance that a challenging economic environment or an economic downturn will not impact our liquidity or our ability to obtain financing in the future.

Convertible Senior Notes

On December 18, 2025, we completed a private offering (the “offering”) of 0.250% convertible senior notes (the “convertible senior notes”) with a maturity date of June 15, 2029, unless earlier repurchased, redeemed or converted. The aggregate principal amount of the convertible senior notes sold in the offering was $2.0 billion, which includes $250 million in aggregate principal amount of convertible senior notes issued pursuant to the initial purchasers’ option to purchase additional convertible senior notes on the same terms and conditions, which the initial purchasers exercised in full for settlement on December 18, 2025.

The convertible senior notes were issued pursuant to an indenture, dated as of December 18, 2025, between us and Deutsche Bank Trust Company Americas, as trustee. If we call any convertible senior notes for redemption, a "make-whole fundamental change" will occur under the indenture with respect to those convertible senior notes, in which case the conversion rate applicable to the conversion of those convertible senior notes will be increased if they are converted during a specified period of time after they are called for redemption. The convertible senior notes are convertible at an initial conversion price of approximately $148.20 per share of common stock. Prior to March 15, 2029, the convertible senior notes are convertible during certain periods only: (i) if the trading price of our common stock is greater than or equal to 130% of the conversion price for at least 20 trading days (whether or not consecutive) during the 30 consecutive trading days prior to the end of a calendar quarter, (ii) the trading price per $1,000 principal amount of convertible senior notes for each trading day of the specified measurement period was less than 98% of the product of the last reported sale price of our common stock and the conversion rate on each such trading day, (iii) if we call the notes for redemption and (iv) upon the occurrence of certain corporate events, as set forth in the indenture. On or after March 15, 2029, holders may convert all or any portion of their notes, regardless of the foregoing conditions. Upon any conversion of the convertible senior notes, we will pay cash up to the aggregate principal amount of the notes to be converted and pay or deliver, as the case may be, cash, shares of our common stock or a combination thereof, at our election, in respect of the remainder, if any, of our conversion obligation in excess of the aggregate principal amount of the notes being converted.

The net proceeds from the offering were $1,970 million, after deducting the initial purchasers’ discounts and expenses of $30 million. We used the net proceeds from the offering as follows: (i) $187 million to fund the cost of entering into the capped call transactions described below, (ii) $248 million to purchase approximately 2.1 million shares of Zoetis’ common stock, par value $0.01 per share (the “common stock”), in privately negotiated transactions entered into concurrently with the pricing of the offering effected with or through one of the initial purchasers or its affiliate and (iii) the remaining $1,535 million for additional repurchases of common stock following the date of the offering, which repurchases were substantially completed as of December 31, 2025.

In connection with the issuance of the convertible senior notes, we also entered into privately negotiated capped call transactions with certain counterparties (the “capped calls”). The capped calls each have a strike price of approximately $148.20 per share, subject to certain adjustments, which correspond to the initial conversion price of the convertible senior notes. The capped calls have initial cap prices of approximately $211.72 per share, subject to certain adjustments. The capped calls cover, subject to anti-dilution adjustments, approximately 13.5 million shares of our common stock. We have the option to settle the capped calls in either shares, cash or a combination thereof. The capped calls are generally intended to reduce or offset the potential dilution to our common stock upon any conversion of the convertible senior notes with such reduction or offset, as the case may be, subject to a cap based on the cap price. However, if the market price per share of our common stock, as measured under the terms of the capped calls, exceeds the cap prices of the capped calls, there would nevertheless be dilution and/or there would not be an offset of such cash payments, in each case, to the extent that such market price exceeds the cap price of the capped calls. The capped calls are separate transactions, and not part of the terms of the convertible senior notes. We analyzed the transactions under ASC 815, Derivatives and Hedging, and determined that the capped calls met the criteria for classification as an equity transaction with no subsequent remeasurement, as long as they continue to meet the conditions for equity classification. These capped calls are recorded in stockholders’ equity on our balance sheet and are not accounted for as a bifurcated derivative. The cost of the capped calls of $187 million, net of $42 million in deferred tax assets, was recorded as a decrease to Additional paid-in capital on our Consolidated Balance Sheets as of December 31, 2025.

On December 17, 2025, we and the lenders under the credit facility entered into the First Waiver to the Revolving Credit Agreement, dated as of December 17, 2025 (the “waiver”), among us, the lenders party thereto, the issuing banks party thereto and JPMorgan Chase Bank, N.A., as administrative agent. The waiver waived a technical provision in the credit facility and explicitly permits early conversions of the convertible senior notes pursuant to their terms.

Senior Notes and Other Long-Term Debt

On August 18, 2025, we issued $850 million aggregate principal amount of 4.150% senior notes due 2028 and $1.00 billion aggregate principal amount of 5.000% senior notes due 2035 (collectively, 2025 senior notes), with an original issue discount of $2 million. The net proceeds were used to redeem in full the $600 million aggregate principal amount of our 5.400% 2022 senior notes due 2025 and the $750 million aggregate principal amount of our 4.500% 2015 senior notes due 2025 on August 28, 2025 and September 17, 2025, respectively, and the remainder is being used for general corporate purposes.

Our senior notes are governed by an indenture and supplemental indentures (collectively, the indenture) between us and Deutsche Bank Trust Company Americas, as trustee. The indenture contains certain covenants, including limitations on our and certain of our subsidiaries' ability to incur liens or engage in sale lease-back transactions. The indenture also contains restrictions on our ability to consolidate, merge or sell substantially all of our assets. In addition, the indenture contains other customary terms, including certain events of default, upon the occurrence of which the senior notes may be declared immediately due and payable.

Table of Contents

Pursuant to the indenture, we are able to redeem the senior notes of any series, in whole or in part, at any time by paying a “make whole” premium, plus accrued and unpaid interest to, but excluding, the date of redemption. Upon the occurrence of a change of control of us and a downgrade of the senior notes below an investment grade rating by each of Moody's Investors Service, Inc. and Standard & Poor's Ratings Services, we are, in certain circumstances, required to make an offer to repurchase all of the outstanding senior notes at a price equal to 101% of the aggregate principal amount of the senior notes together with accrued and unpaid interest to, but excluding, the date of repurchase.

Credit ratings

Two major corporate debt-rating organizations, Moody's and S&P, assign ratings to our short-term and long-term debt. A security rating is not a recommendation to buy, sell or hold securities and the rating is subject to revision or withdrawal at any time by the rating organization. Each rating should be evaluated independently of any other rating.

The following table provides the current ratings assigned by these rating agencies to our commercial paper and senior unsecured non-credit-enhanced long-term debt:

Pension obligations

We maintain pension obligations associated with certain international defined benefit plans and expect to contribute a total of $8 million to these plans in 2026. As of December 31, 2025, the supplemental savings plan liability was $47 million. For additional information, see Notes to Consolidated Financial Statements— Note 14. Benefit Plans.

Share repurchase program

In August 2024, our Board of Directors authorized a multi-year share repurchase program of up to $6 billion of our outstanding common stock. In connection with the December 18, 2025 private offering of 0.250% convertible senior notes, we purchased approximately 2.1 million shares of Zoetis’ common stock, par value $0.01 per share, in privately negotiated transactions entered into concurrently with the pricing of the convertible senior notes offering effected with or through one of the initial purchasers or its affiliate. Following the date of the offering, we used $1,535 million of the remaining proceeds from the offering for additional repurchases of common stock which repurchases were substantially completed as of December 31, 2025. As of December 31, 2025, there was $2.4 billion remaining under this authorization. Purchases of Zoetis shares may be made at the discretion of management, depending on market conditions and business needs. Share repurchases may be executed through various means, including open market or privately negotiated transactions. During 2025, 23.9 million shares were repurchased for $3.2 billion, which excludes a $31 million accrual for excise tax on net share repurchases.

Off-balance sheet arrangements

In the ordinary course of business and in connection with the sale of assets and businesses, we may indemnify our counterparties against certain liabilities that may arise in connection with a transaction or that are related to activities prior to a transaction. These indemnifications typically pertain to environmental, tax, employee and/or product-related matters, and patent-infringement claims. If the indemnified party were to make a successful claim pursuant to the terms of the indemnification, we would be required to reimburse the loss. These indemnifications are generally subject to threshold amounts, specified claim periods and other restrictions and limitations. Historically, we have not paid significant amounts under these provisions and, as of December 31, 2025 and 2024, recorded amounts for the estimated fair value of these indemnifications are not material.

Overview of our business

We are a global leader in the animal health industry, focused on the discovery, development, manufacture and commercialization of medicines, vaccines, diagnostic products and services, biodevices, genetic tests and precision animal health. For over 70 years, we have been innovating ways to predict, prevent, detect, and treat animal illness, and continue to stand by those raising and caring for animals worldwide - from veterinarians and pet owners to livestock producers.

We manage our operations through two geographic operating segments: the United States (U.S.) and International. Within each of these operating segments, we offer diverse products for both companion animals and livestock customers in order to capitalize on local and regional trends and customer needs. See Notes to Consolidated Financial Statements—Note 19. Segment Information.

We directly market our products to veterinarians and livestock producers located in approximately 45 countries across North America, Europe, Africa, Asia, Australia and South America, and are a market leader in nearly all of the major regions in which we operate. Through our efforts to establish an early and direct presence in many emerging markets, such as Brazil, Chile, China and Mexico, we believe we are one of the largest animal health medicines and vaccines businesses as measured by revenue across emerging markets as a whole. In markets where we do not have a direct commercial presence, we generally contract with distributors that provide logistics and sales and marketing support for our products.

We believe our investments in one of the industry’s largest sales organizations, including our extensive network of technical and veterinary operations specialists, our high-quality manufacturing and reliability of supply, and our long track record of developing products that meet customer needs, has led to enduring and valued relationships with our customers. Our research and development (R&D) efforts enable us to deliver innovative products to address unmet needs and evolve our products so that they remain relevant for our customers.

We have approximately 300 product lines that we sell in over 100 countries for the prediction, prevention, detection and treatment of diseases and conditions that affect various companion animal and livestock species. The diversity of our product portfolio and our global operations provides stability to our overall business.

A summary of our 2024 performance compared with the comparable 2023 and 2022 periods follows:

Our operating environment

Industry

The animal health industry, which focuses on both companion animals and livestock, is a growing industry that impacts billions of people worldwide. The primary companion animal species are dogs, cats and horses. Factors influencing growth in demand for companion animal medicines, vaccines and diagnostics include:

•increasing pet owners’ commitment to the health and well-being of their pets;

•economic development and related increases in disposable income, particularly in many emerging markets;

•companion animals living longer;

•increasing medical treatment of companion animals; and

•advances in companion animal medicines, vaccines and diagnostics.

The primary livestock species are cattle (both beef and dairy), swine, poultry, fish and sheep. Livestock health and production are essential to meeting the growing demand for animal protein of a global population. Factors influencing growth in demand for livestock medicines and vaccines

31 |

Table of Contents

include:

•human population growth and increasing standards of living, particularly in many emerging markets;

•increasing demand for improved nutrition, particularly animal protein;

•natural resource constraints, such as scarcity of arable land, fresh water and increased competition for cultivated land, resulting in fewer resources that will be available to meet an increasing demand for animal protein;

•increasing urbanization; and

•increased focus on food safety and food security.

The overall economic environment

In addition to industry-specific factors, we, like other businesses, face challenges related to global economic conditions, an economic downturn and high inflation. Growth in both the livestock and companion animal sectors is driven by overall economic development and related growth, particularly in many emerging markets. In the past, certain of our customers and suppliers have been affected directly by shortages in veterinary healthcare workers and economic downturns or inflation, which decreased the demand for our products and, in some cases, hindered our ability to collect amounts due from customers.

Industry sources have reported that pet owners indicated a preference for reducing spending on other aspects of their lifestyle, including entertainment, clothing and household goods, before reducing spending on pet healthcare. Similarly, the cost of medicines and vaccines to our livestock producer customers is small relative to other production costs, including feed, and the use of these products is intended to improve livestock producers’ economic outcomes. As a result, demand for our products has historically been more stable than demand for other production inputs. Each of these factors, plus our broad and innovative portfolio, contributes to our ability to incorporate inflationary challenges into our product pricing and mitigate the impact on our results. While these factors have mitigated the impact of prior downturns in the global economy, economic challenges, including an economic downturn and inflation, could increase cost sensitivity among our customers, which may result in reduced demand for our products, which could have a material adverse effect on our operating results and financial condition.

Competition

The animal health industry is highly competitive. Although our business is the largest based on revenue in the animal health industry (which includes medicines, vaccines and diagnostics), we face competition in the regions in which we operate. Principal methods of competition vary depending on the particular region, species, product category or individual product. Some of these methods include new product development, quality, price, service and promotion to veterinary professionals, pet owners and livestock producers. Our competitors include standalone animal health businesses and the animal health businesses of large pharmaceutical companies. In recent years, there has been an increase in consolidation in the animal health industry. There are also many start-up companies working in the animal health area. In addition to competition from established market participants, there could be new entrants to the animal health medicines, vaccines and diagnostics industry in the future. We also compete with companies that produce generic products, following our products’ loss of exclusivity in a given market. For example, Draxxin currently competes with generic products in key markets including the U.S., Europe, Canada, Mexico and Australia. Since 2021, the first year of generic competition, sales of Draxxin declined by 49% in the U.S., its largest market. For more information regarding the generic competition we expect to encounter as patents on certain of our key products expire, see Item 1. Business – Intellectual Property.

Manufacturing and supply

In order to sell our products, we must be able to produce and ship our products in sufficient quantities. Many of our products involve complex manufacturing processes and are sole-sourced from certain manufacturing sites. Minor deviations in our manufacturing or logistical processes, such as temperature excursions or improper package sealing, could result in delays, inventory shortages, unanticipated costs, product recalls, product liability and/or regulatory action. In addition, a number of factors could cause production interruptions that could result in launch delays, inventory shortages, recalls, unanticipated costs or issues with our supply agreements with third parties.

Our manufacturing network may be unable to meet the demand for our products or we may have excess capacity if demand for our products changes. The unpredictability of a product's regulatory or commercial success or failure, the lead time necessary to construct highly technical and complex manufacturing sites, and shifting customer demand increase the potential for capacity imbalances.

Perceptions of product quality, safety and reliability

We believe that animal health customers value high-quality manufacturing and reliability of supply. The importance of quality and safety concerns to pet owners, veterinarians and livestock producers also contributes to animal health brand loyalty, which often continues after the loss of patent-based and regulatory exclusivity. We depend on positive perceptions of the safety and quality of our products by our customers, veterinarians and end-users.

In addition, negative beliefs about animal health products generally could impact demand for our products. For example, the issue of the potential transfer of increased antibacterial resistance in bacteria from food-producing animals to human pathogens, and the causality of that transfer, continue to be the subject of global scientific and regulatory discussion. In some countries, this issue has led to government restrictions and bans on the use of specific antibacterials in some food-producing animals, regardless of the route of administration (in feed or injectable). In addition, consumer preferences in some markets have impacted the use of antibacterials in food producing animals. Such restrictions and consumer preferences in some cases may negatively impact sales of our antibacterial products, but in other instances may increase sales of our products that can be used as antibacterial alternatives. Our total revenue attributable to antibacterials for livestock was approximately $950 million for the year ended December 31, 2024. As a result of the divestiture of our medicated feed additive product portfolio, certain water soluble products and related assets, we anticipate our total revenues attributable to antibacterials for livestock will decrease.

Similarly, concerns regarding greenhouse gas emissions and other potential environmental impacts of livestock production have led to some consumers opting to limit or avoid consuming animal products. However, we believe the impact of this trend is limited as the livestock industry is still expected to continue to grow in order to feed a growing global population.

Product development initiatives

Our future success depends on both our existing products and our pipeline of new products, including new products that we may develop through joint ventures and products that we are able to obtain through license or acquisition. We believe we are an industry leader in animal health R&D, with a track record of generating new products and product lifecycle innovation, which is defined as R&D programs that leverage existing animal health products by adding new species or claims, achieving approvals in new markets or creating new reformulations, modifications and combinations. The majority of our R&D programs focus on new products. In addition to traditional medicines and vaccines, we develop products across additional categories to address the needs of veterinarians and producers to predict, prevent, detect and treat conditions in both companion animals and livestock, including products and services in diagnostics, genetics, precision animal health and digital and data analytics.

Changing distribution channels for companion animal products

In most markets, companion animal owners typically purchase their animal health products directly from veterinarians. However, in the U.S. and certain other markets, companion animal owners increasingly have the option to purchase animal health products from sources other than veterinarians, such as internet-based retailers, “big-box” retail stores or other over-the-counter distribution channels. We believe the ability of pet owners to purchase our products online and from retail stores may increase pet owner compliance and result in increased sales. However, over time, we may be unable to sustain our current margins due to the increased purchasing power of such retailers as compared to traditional veterinary practices.

In addition, this trend could negatively impact the sales of products we primarily sell through the veterinarian distribution channel, as any decrease in visits to veterinarians by companion animal owners could reduce our market share and sales of such products. A reduction in the number of pet owners who purchase our products directly from their veterinarian could also lead to increased use of generic alternatives to our products or the increased substitution of our products with other animal health products or human health products if such other products are deemed to be lower-cost alternatives.

Disease Outbreaks

Sales of our livestock products have in the past, and may in the future be, adversely affected by the outbreak of disease carried by animals. Outbreaks of disease may reduce regional or global sales of particular animal-derived food products or result in reduced exports of such products, either due to heightened export restrictions or import prohibitions, which may reduce demand for our products. Also, the outbreak of any highly contagious disease near our main production sites could require us to immediately halt production of our products at such sites or force us to incur substantial expenses in procuring raw materials or products elsewhere. Alternatively, sales of products that treat specific disease outbreaks may increase.

Foreign exchange rates

Significant portions of our revenue and costs are exposed to changes in foreign exchange rates. Our products are sold in more than 100 countries and, as a result, our revenue is influenced by changes in foreign exchange rates. For the year ended December 31, 2024, approximately 41% of our revenue was denominated in foreign currencies. We seek to manage our foreign exchange risk, in part, through operational means, including managing same-currency revenue in relation to same-currency costs and same-currency assets in relation to same-currency liabilities. As we operate in multiple foreign currencies, including the Australian dollar, Brazilian real, British pound, Canadian dollar, Chinese renminbi, euro and other currencies, changes in those currencies relative to the U.S. dollar will impact our revenue, cost of goods and expenses, and consequently, net income. Exchange rate fluctuations may also have an impact beyond our reported financial results and directly impact operations. These fluctuations may affect the ability to buy and sell our goods and services between markets impacted by significant exchange rate variances. For the year ended December 31, 2024, approximately 59% of our total revenue was in U.S. dollars. Our year-over-year total revenue growth was unfavorably impacted by 3% from changes in foreign currency values relative to the U.S. dollar.

Weather conditions, climate change and the availability of natural resources

The animal health industry and demand for many of our animal health products in a particular region are affected by weather conditions, as usage of our products follows varying weather patterns and weather-related pressures from pests, such as ticks. As a result, we may experience regional and seasonal fluctuations in our results of operations.

In addition, veterinary hospitals and practitioners depend on visits from and access to the animals under their care. Veterinarians’ patient volume and ability to operate could be adversely affected if they experience prolonged snow, ice or other severe weather conditions, particularly in regions not accustomed to sustained inclement weather. Furthermore, weather conditions, including excessive cold or heat, natural disasters and other events, could negatively impact our livestock customers by impairing the health or growth of their animals or the production or availability of feed, as well as disrupting their normal operations. For example, livestock producers depend on the availability of natural resources, including large supplies of fresh water. Their animals’ health and their ability to operate could be adversely affected if they experience a shortage of fresh water due to human population growth, climate change or floods, droughts or other weather conditions. In the event of adverse weather conditions, climate-change related impacts or a shortage of fresh water, veterinarians and livestock producers may purchase less of our products.

Adverse weather conditions, natural disasters and climate change may also impact the aquaculture business. Changes in water temperatures could affect the timing of reproduction and growth of various fish species, as well as trigger the outbreak of certain waterborne diseases.

Components of revenue and costs and expenses

Our revenue, costs and expenses are reported for the year ended December 31 for each year presented, except for operations outside the U.S., for which the financial information is included in our consolidated financial statements for the fiscal year ended November 30 for each year presented.

Revenue

Our revenue is primarily derived from our diversified product portfolio of medicines, vaccines and diagnostic products and services used to treat and protect companion animals and livestock. Generally, our products are promoted to veterinarians and livestock producers by our sales organization which includes sales representatives and technical and veterinary operations specialists, and then sold directly by us or through distributors, retailers or e-commerce outlets. The depth of our product portfolio enables us to address the varying needs of customers in different species and geographies. In 2024, our two top-selling products and product lines, Simparica/Simparica Trio and Apoquel/Apoquel Chewable, contributed approximately 15% and 11% of our revenue, respectively, and combined with our next three top-selling products and product lines, Cytopoint, Librela and our ceftiofur line, these five products and product lines contributed approximately 41% of our revenue. Our ten top-selling products and product lines contributed 55% of our revenue. For additional information regarding our products, including descriptions of our product lines that each represented approximately 1% or more of our revenue in 2024, see Item 1. Business—Products.

Costs and expenses

Costs of sales consist primarily of cost of materials, facilities and other infrastructure used to manufacture our medicine and vaccine products, as well as costs to operate our reference labs and royalty expenses associated with the intellectual property of our products, when relevant.

Selling, general and administrative (SG&A) expenses consist of, among other things, the internal and external costs of marketing, promotion, advertising and shipping and handling as well as certain costs related to business technology, facilities, legal, finance, human resources, business development, public affairs and procurement.

Research and development (R&D) expenses consist primarily of project costs specific to new product R&D and product lifecycle innovation, overhead costs associated with R&D operations and investments that support local market clinical trials for approved indications and expenses related to regulatory approvals for our products. We do not disaggregate R&D expenses by research stage or by therapeutic area for purposes of managing our business.

Amortization of intangible assets consists primarily of the amortization expense for identifiable finite-lived intangible assets that have been acquired through business combinations. These assets consist of, but are not limited to, developed technology, brands and trademarks.

Restructuring charges and certain acquisition and divestiture-related costs consist of all restructuring charges (those associated with cost reduction/productivity initiatives and those associated with acquisition activity) and costs associated with executing the transaction which include acquiring and integrating businesses and costs associated with divesting and disintegrating businesses. Restructuring charges are associated with employees, assets and activities that will not continue in the company. Acquisition and divestiture-related costs are associated with acquiring and integrating acquired businesses, which may include expenditures for consulting and the integration of systems and processes, product transfers, transaction costs and restructuring the company, as well as costs associated with divesting and disintegrating a portion of our business which may include expenditures for consulting and the disintegration of systems and processes, transfer costs, and restructuring charges which may include charges related to employees, assets and activities that will not continue in the company's ongoing operations.

Other (income)/deductions—net consists of various items, primarily net (gains)/losses on business sales and divestitures, as well as asset disposals, interest income, royalty-related income, foreign exchange translation (gains)/losses and certain asset impairment charges.

Significant accounting policies and application of critical accounting estimates

In presenting our financial statements in conformity with U.S. GAAP, we are required to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenue, costs and expenses and related disclosures. For a description of our significant accounting policies, see Notes to Consolidated Financial Statements—Note 3. Significant Accounting Policies.

We believe that the following accounting policies are critical to an understanding of our consolidated financial statements as they require the application of the most difficult, subjective and complex judgments and, therefore, could have the greatest impact on our financial statements: (i) fair value; (ii) revenue; (iii) asset impairment reviews; and (iv) contingencies.

Below are some of our more critical accounting estimates. See Notes to Consolidated Financial Statements—Note 3. Significant Accounting Policies: Estimates and Assumptions for a discussion about the risks associated with estimates and assumptions.

Fair value

For a discussion about the application of fair value to our long-term debt and financial instruments, see Notes to Consolidated Financial Statements—Note 9. Financial Instruments.

For a discussion about the application of fair value to our business combinations, see Notes to Consolidated Financial Statements—Note 3. Significant Accounting Policies: Fair Value.

For a discussion about the application of fair value to our asset impairment reviews, see Asset impairment reviews below.

Revenue

Our gross product revenue is subject to deductions that are generally estimated and recorded in the same period that the revenue is recognized and primarily represents sales returns and revenue incentives. For example:

•for sales returns, we perform calculations in each market that incorporate the following, as appropriate: local returns policies and practices; past returns as a percentage of revenue; an understanding of the reasons for past returns; estimated shelf life by product; an estimate of the amount of time between shipment and return or lag time; and any other factors that could impact the estimate of future returns, product recalls, discontinuation of products or a changing competitive environment; and

•for revenue incentives, we use our historical experience with similar incentives programs to estimate the impact of such programs on revenue.

If any of our ratios, factors, assessments, experiences or judgments are not indicative or accurate predictors of our future experience, our results could be materially affected. Although the amounts recorded for these revenue deductions are dependent on estimates and assumptions, historically our adjustments to actual results have not been material. The sensitivity of our estimates can vary by program, type of customer and geographic location.

Amounts recorded for revenue deductions can result from a complex series of judgments about future events and uncertainties and can rely on estimates and assumptions. For further information about the risks associated with estimates and assumptions, see Notes to Consolidated Financial Statements—Note 3. Significant Accounting Policies: Estimates and Assumptions.

Asset impairment reviews

We review all of our long-lived assets for impairment indicators throughout the year and we perform detailed testing whenever impairment indicators are present. In addition, we perform impairment testing for goodwill and indefinite-lived intangible assets at least annually. When necessary, we record charges for impairments of long-lived assets for the amount by which the fair value is less than the carrying value of these assets.

Our impairment review processes are described below and in Notes to Consolidated Financial Statements—Note 3. Significant Accounting Policies: Amortization of Intangible Assets, Depreciation and Certain Long-Lived Assets and, for deferred tax assets, in Note 3. Significant Accounting Policies: Deferred Tax Assets and Liabilities and Income Tax Contingencies.

Examples of events or circumstances that may be indicative of impairment include:

•a significant adverse change in the extent or manner in which an asset is used. For example, restrictions imposed by the regulatory authorities could affect our ability to manufacture or sell a product; and

•a projection or forecast that demonstrates losses or reduced profits associated with an asset. This could result, for example, from the introduction of a competitor’s product that results in a significant loss of market share or the inability to achieve the previously projected revenue growth, or from the lack of acceptance of a product by customers.

For finite-lived identifiable intangible assets, such as developed technology rights, and for other long-lived assets, such as property, plant and equipment, whenever impairment indicators are present, we calculate the undiscounted value of the projected cash flows associated with the asset, or asset group, and compare this estimated amount to the carrying amount. If the carrying amount is found to be greater, we record an impairment loss for the excess of book value over fair value. In addition, in all cases of an impairment review, we re-evaluate the remaining useful lives of the assets and modify them, as appropriate.

Our impairment reviews of most of our long-lived assets depend on the determination of fair value, as defined by U.S. GAAP, and these judgments can materially impact our results of operations. A single estimate of fair value can result from a complex series of judgments about future events and uncertainties and can rely on estimates and assumptions. For information about the risks associated with estimates and assumptions, see Notes to Consolidated Financial Statements—Note 3. Significant Accounting Policies: Estimates and Assumptions.

Intangible assets other than goodwill

We test indefinite-lived intangible assets for impairment at least annually, or more frequently if impairment indicators exist, by first assessing qualitative factors to determine whether it is more likely than not that the fair value of the indefinite-lived intangible asset is less than its carrying amount. If we conclude it is more likely than not that the fair value is less than the carrying amount, a quantitative test that compares the fair value of

35 |

Table of Contents

the indefinite-lived intangible asset with its carrying value is performed. If the fair value is less than the carrying amount, an impairment loss is recognized. Impairments of identifiable intangible assets other than goodwill, are recorded in Restructuring charges and certain acquisition and divestiture-related costs and Other (income)/deductions—net, as applicable. We did not have any material intangible asset impairment charges for the years ended December 31, 2024, 2023 and 2022.

When we are required to determine the fair value of intangible assets other than goodwill, we use an income approach, specifically the multi-period excess earnings method, also known as the discounted cash flow method. We start with a forecast of all the expected net cash flows associated with the asset, which includes the application of a terminal value for indefinite-lived assets, and then we apply an asset-specific discount rate to arrive at a net present value amount. Some of the more significant estimates and assumptions inherent in this approach include: the amount and timing of the projected net cash flows, which includes the expected impact of competitive, legal and/or regulatory forces on the projections, the impact of technological risk associated with IPR&D assets, as well as the selection of a long-term growth rate; the discount rate, which seeks to reflect the risks inherent in the projected cash flows; foreign currency fluctuations; and the effective tax rate, which seeks to incorporate the geographic diversity of the projected cash flows.

While all identifiable intangible assets can be impacted by events and thus lead to impairment, in general, identifiable intangible assets that are at the highest risk of impairment include IPR&D assets ($136 million as of December 31, 2024). IPR&D assets are higher-risk assets given the uncertain nature of R&D activity.

For a description of our accounting policy, see Notes to Consolidated Financial Statements—Note 3. Significant Accounting Policies: Amortization of Intangible Assets, Depreciation and Certain Long-Lived Assets.

Goodwill

Goodwill represents the excess of the consideration transferred over the fair value of net assets of businesses purchased and is assigned to reporting units. We test goodwill for impairment on at least an annual basis, or more frequently if necessary, either by assessing qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount or by performing a periodic quantitative assessment.

Factors considered in the qualitative assessment include general macroeconomic conditions, conditions specific to the industry and market, cost factors which could have a significant effect on earnings or cash flows, the overall financial performance of the reporting unit and whether there have been sustained declines in our share price. Additionally, we evaluate the extent to which the fair value exceeded the carrying value of the reporting unit at the date of the last quantitative assessment performed.

When performing a quantitative assessment to test for goodwill impairment we utilize the income approach, which is forward-looking, and relies primarily on internal forecasts. Within the income approach, the method that we use is the discounted cash flow method. We start with a forecast of all the expected net cash flows associated with the reporting unit, which includes the application of a terminal value, and then apply a reporting unit-specific discount rate to arrive at a net present value. Some of the more significant estimates and assumptions inherent in this approach include: the amount and timing of the projected net cash flows, which includes the expected impact of technological risk and competitive, legal and/or regulatory forces on the projections, as well as the selection of a long-term growth rate; the discount rate, which seeks to reflect the various risks inherent in the projected cash flows; and the effective tax rate, which seeks to incorporate the geographic diversity of the projected cash flows.

We test goodwill for impairment on at least an annual basis, or more frequently if necessary, either by assessing qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount or by performing a periodic quantitative assessment. In 2024, we performed a periodic quantitative impairment assessment as of September 30, 2024, which did not result in the impairment of goodwill associated with any of our reporting units. In 2023, we performed a qualitative impairment assessment as of September 30, 2023, which did not result in the impairment of goodwill associated with any of our reporting units.

For all of our reporting units, there are a number of future events and factors that may impact future results and that could potentially have an impact on the outcome of subsequent goodwill impairment testing. For a list of these factors, see Forward-looking statements and factors that may affect future results.

For a description of our accounting policy, see Notes to Consolidated Financial Statements—Note 3. Significant Accounting Policies: Amortization of Intangible Assets, Depreciation and Certain Long-Lived Assets.

Contingencies

For a discussion about income tax contingencies, see Notes to Consolidated Financial Statements—Note 8C. Tax Matters: Tax Contingencies.

For a discussion about legal contingencies, guarantees and indemnifications, see Notes to Consolidated Financial Statement—Note 18. Commitments and Contingencies.

Non-GAAP financial measures

We report information in accordance with U.S. generally accepted accounting principles (GAAP). Management also measures performance using non-GAAP financial measures that may exclude certain amounts from the most directly comparable GAAP measure. Despite the importance of these measures to management in goal setting and performance measurement, non-GAAP financial measures have no standardized meaning prescribed by U.S. GAAP and, therefore, have limits in their usefulness to investors and may not be comparable to the calculation of similar measures of other companies. We present certain identified non-GAAP measures solely to provide investors with useful information to more fully understand how management assesses performance.

Operational Growth

We believe that it is important to not only understand overall revenue and earnings growth, but also “operational growth.” Operational growth is a non-GAAP financial measure defined as revenue or earnings growth excluding the impact of foreign exchange. This measure provides information on the change in revenue and earnings as if foreign currency exchange rates had not changed between the current and prior periods to facilitate a

36 |

Table of Contents

period-to-period comparison. We believe this non-GAAP measure provides a useful comparison to previous periods for the company and investors, but should not be viewed as a substitute for U.S. GAAP reported growth.

Adjusted Net Income and Adjusted Earnings Per Share

Adjusted net income and the corresponding adjusted earnings per share (EPS) are non-GAAP financial measures of performance used by management. We believe these financial measures are useful supplemental information to investors when considered together with our U.S. GAAP financial measures. We report adjusted net income to portray the results of our major operations, and the discovery, development, manufacture and commercialization of our products, prior to considering certain income statement elements. We define adjusted net income and adjusted EPS as net income attributable to Zoetis and EPS before the impact of purchase accounting adjustments, acquisition and divestiture-related costs and certain significant items.

We recognize that, as an internal measure of performance, the adjusted net income and adjusted EPS measures have limitations, and we do not restrict our performance management process solely to these metrics. A limitation of the adjusted net income and adjusted EPS measures is that they provide a view of our operations without including all events during a period, such as the effects of an acquisition or amortization of purchased intangibles, and do not provide a comparable view of our performance to other companies. The adjusted net income and adjusted EPS measures are not, and should not be viewed as, a substitute for U.S. GAAP reported net income attributable to Zoetis and reported EPS. See the Adjusted Net Income section below for more information.

The effective tax rate for 2024, as compared to 2023, was primarily attributable to the favorable impact of a higher benefit in the U.S. related to foreign-derived intangible income and lower net discrete tax expenses, offset by a less favorable jurisdictional mix of earnings (which includes the impact of the location of earnings, repatriation costs and the Organisation for Economic Co-operation and Development (OECD) global minimum tax provision (Pillar Two)). Jurisdictional mix of earnings can vary depending on repatriation decisions, operating fluctuations in the normal course of business and the impact of non-deductible items and non-taxable items.

Pillar Two was effective beginning in 2024 and the impact of these provisions is included in our effective tax rate for 2024.

2024 vs. 2023

U.S. operating segment

U.S. segment revenue increased by $519 million, or 11%, in 2024 compared with 2023, of which $525 million resulted from growth in companion animal products and $6 million decline in livestock products.

•Companion animal revenue growth was primarily due to growth in sales of Simparica Trio, our mAb products for OA pain, Librela and Solensia, and key dermatology products, partially offset by lower sales of our small animal vaccines.

•Livestock revenue declined due to the impact of the divestiture of our medicated feed additive product portfolio, certain water soluble products and related assets, partially offset by higher sales of cattle products, driven by timing of supply and strong demand for our ceftiofur product line.

U.S. segment earnings increased by $473 million, or 17%, in 2024 compared with 2023, primarily due to higher revenue, partially offset by higher cost of sales and operating expenses.

International operating segment

International segment revenue increased by $191 million, or 5%, in 2024 compared with 2023. Operational revenue growth was $401 million, or 10%, reflecting growth of $257 million in companion animal products and $144 million in livestock products.

•Companion animal operational revenue growth was driven primarily by the growth in sales of our key dermatology products, mAb products for OA pain, Librela and Solensia, small animal parasiticides and vaccine products.

•Livestock operational revenue growth was due to increased sales of cattle, poultry and fish products, partially offset by a decline in sales of sheep products. Sales of cattle products grew due to price, partially offset by volume declines as compared to the prior year period due to prior year supply recoveries. Sales of products in our poultry portfolio grew due to price and demand generation efforts in key poultry markets. Sales of our fish portfolio grew due to increased vaccine sales in Norway, partially offset by lower sales of parasiticides in Chile. Sales of sheep products declined primarily due to supply constraints in Australia compounded by poor market conditions.

•Additionally, International segment revenue was unfavorably impacted by foreign exchange which decreased revenue by approximately $210 million, or 5%, primarily driven by fluctuations in the Argentinian peso, Brazilian real, Turkish lira, Japanese yen and Egyptian pound.

International segment earnings increased by $81 million, or 4%, in 2024 compared with 2023. Operational earnings growth was $230 million, or 11%, primarily due to higher revenue, partially offset by higher cost of sales and operating expenses.

Other business activities

Other business activities includes our Client Supply Services contract manufacturing results, our human health business and expenses associated with our dedicated veterinary medicine research and development organization, research alliances, U.S. regulatory affairs and other operations focused on the development of our products. Other R&D-related costs associated with non-U.S. market and regulatory activities are generally included in the International segment.

2024 vs. 2023

Other business activities net loss increased by $66 million, or 13%, in 2024 compared with 2023, reflecting an increase in R&D costs due to an increase in higher project investments, certain compensation-related costs to support innovation, acquisitions and other operating costs.

Reconciling items

Reconciling items include certain costs that are not allocated to our operating segments results, such as costs associated with the following:

•Corporate, which includes certain costs associated with information technology, facilities, legal, finance, human resources, business development, certain diagnostics costs and communications, among others. These costs also include certain compensation costs, certain procurement costs, and other miscellaneous operating expenses that are not charged to our operating segments, as well as interest income and expense;

Table of Contents

•Certain transactions and events such as Purchase accounting adjustments, Acquisition and divestiture-related activities and Certain significant items, which are defined below; and

•Other unallocated, which includes (i) certain overhead expenses associated with our global manufacturing operations not charged to our operating segments; (ii) certain costs associated with finance that specifically support our global manufacturing operations; (iii) certain supply chain and global logistics costs; and (iv) certain procurement costs.

2024 vs. 2023

Corporate expenses increased by $171 million, or 16%, in 2024 compared with 2023, primarily due to higher compensation-related costs, a settlement received from a third-party for underpayment of royalties in the prior year period, investments in information technology and unfavorable foreign exchange.

Other unallocated expenses increased by $18 million, or 6%, in 2024 compared with 2023, primarily due to higher manufacturing costs and unfavorable foreign exchange, partially offset by lower freight charges and lower inventory obsolescence.

Adjusted net income

General description of adjusted net income (a non-GAAP financial measure)

Adjusted net income is an alternative view of performance used by management, and we believe that investors’ understanding of our performance is enhanced by disclosing this performance measure. The adjusted net income measure is an important internal measurement for us. Additionally, we measure our overall performance on this basis in conjunction with other performance metrics. The following are examples of how the adjusted net income measure is utilized:

•senior management receives a monthly analysis of our operating results that is prepared on an adjusted net income basis;

•our annual budgets are prepared on an adjusted net income basis; and

•other goal setting and performance measurements.

Purchase accounting adjustments

Adjusted net income is calculated prior to considering certain significant purchase accounting impacts that result from business combinations and net asset acquisitions. These impacts, primarily associated with certain acquisitions, include amortization related to the increase in fair value of the acquired finite-lived intangible assets and depreciation related to the increase/decrease to fair value of the acquired fixed assets. Therefore, the adjusted net income measure includes the revenue earned upon the sale of the acquired products without considering the aforementioned significant charges.

While certain purchase accounting adjustments can occur through 20 or more years, this presentation provides an alternative view of our performance that is used by management to internally assess business performance. We believe the elimination of amortization attributable to acquired intangible assets provides management and investors an alternative view of our business results by providing a degree of parity to internally developed intangible assets for which R&D costs previously have been expensed.

A completely accurate comparison of internally developed intangible assets and acquired intangible assets cannot be achieved through adjusted net income. These components of adjusted net income are derived solely from the impact of the items listed above. We have not factored in the impact of any other differences in experience that might have occurred if we had discovered and developed those intangible assets on our own, and this approach does not intend to be representative of the results that would have occurred in those circumstances. For example, our R&D costs in total, and in the periods presented, may have been different; our speed to commercialization and resulting revenue, if any, may have been different; or our costs to manufacture may have been different. In addition, our marketing efforts may have been received differently by our customers. As such, in total, there can be no assurance that our adjusted net income amounts would have been the same as presented had we discovered and developed the acquired intangible assets.

Acquisition and divestiture-related costs

Adjusted net income is calculated prior to considering transaction, integration and disintegration costs associated with significant business combinations, net asset acquisitions and divestitures. These incremental costs are excluded as they are incurred to acquire and integrate, or dispose and disintegrate, certain businesses as a result of the acquisition or disposal decision and are unique to each transaction. We have made no adjustments for the resulting synergies from these transactions.

We believe that viewing income prior to considering these charges provides investors with a useful additional perspective because the significant costs incurred in a business combination, net asset acquisition or divestiture result primarily from the need to eliminate duplicate assets, activities or employees––a natural result of acquiring or disposing of a fully integrated set of activities. For this reason, we believe that the costs incurred to convert disparate systems, to close duplicative facilities or to eliminate duplicate positions (for example, in the context of a business combination) can be viewed differently from those costs incurred in the ordinary course of business.

The integration and disintegration costs associated with a business combination, asset acquisition or divestiture may occur over several years, with the more significant impacts generally ending within three years of the transaction. Because of the need for certain external approvals for some actions, the span of time needed to achieve certain restructuring and integration or disintegration activities can be lengthy. For example, due to the regulated nature of the animal health medicines, vaccines and diagnostic business, the closure of excess facilities can take several years, as all manufacturing changes are subject to extensive validation and testing and must be approved by the U.S. Food and Drug Administration and/or other regulatory authorities.

Table of Contents

Certain significant items

Adjusted net income is calculated excluding certain significant items. Certain significant items represent substantive, unusual items that are evaluated on an individual basis. Such evaluation considers both the quantitative and the qualitative aspect of their unusual nature. Unusual, in this context, may represent items that are not part of our ongoing business; items that, either as a result of their nature or size, we would not expect to occur as part of our normal business on a regular basis; items that would be nonrecurring; or items that relate to products that we no longer sell. While not all-inclusive, examples of items that could be included as certain significant items would be costs related to a major non-acquisition or divestiture-related restructuring charge and associated implementation costs for a program that is specific in nature with a defined term, such as those related to our non-acquisition or divestiture-related cost-reduction and productivity initiatives; amounts related to disposals of products or facilities that do not qualify as discontinued operations as defined by U.S. GAAP; certain asset impairment charges; adjustments related to the resolution of certain tax positions; significant currency devaluation; the impact of adopting certain significant, event-driven tax legislation; or charges related to legal matters. See Notes to Consolidated Financial Statements— Note 18. Commitments and Contingencies. Our normal, ongoing defense costs or settlements of and accruals on legal matters made in the normal course of our business would not be considered certain significant items.

Reconciliation

A reconciliation of net income attributable to Zoetis, as reported under U.S. GAAP, to adjusted net income follows:

(a)    The effective tax rate on adjusted pretax income was 19.8%, 20.1% and 20.3% in 2024, 2023 and 2022, respectively.

The lower effective tax rate for 2024, as compared to 2023, was primarily attributable to a higher benefit in the U.S. related to foreign-derived intangible income and lower net discrete tax expenses, partially offset by a less favorable jurisdictional mix of earnings (which includes the impact of the location of earnings, repatriation costs and Pillar Two global minimum tax). Jurisdictional mix of earnings can vary depending on repatriation decisions, operating fluctuations in the normal course of business and the impact of non-deductible and non-taxable items.

The lower effective tax rate for 2023, as compared to 2022, was primarily attributable to a higher benefit in the U.S. related to foreign-derived intangible income, a more favorable jurisdictional mix of earnings (which includes the impact of the location of earnings and repatriation costs), partially offset by a higher net discrete tax expense in 2023, mainly related to changes to prior years’ tax positions. Jurisdictional mix of earnings can vary depending on repatriation decisions, operating fluctuations in the normal course of business and the impact of non-deductible and non-taxable items.

Analysis of the Consolidated Statements of Comprehensive Income

Changes in other comprehensive income for the periods presented are primarily related to foreign currency translation adjustments and unrealized gains/(losses) on derivative instruments. The foreign currency translation adjustment changes result from the strengthening or weakening of the U.S. dollar as compared to the currencies in the countries in which we do business. Unrealized gains/(losses) on the changes in the fair value of derivative instruments are recorded within Accumulated other comprehensive income/(loss) and reclassified into earnings depending on the nature and purpose of the financial instrument, as described in Note 9. Financial Instruments of the Notes to Consolidated Financial Statements.

Analysis of the Consolidated Balance Sheets

For a discussion about the changes in Cash and cash equivalents, Short-term borrowings, Current portion of long-term debt and Long-term debt, net of discount and issuance costs, see “Analysis of financial condition, liquidity and capital resources” below.

Inventories decreased primarily due to the divestiture of our medicated feed additive product portfolio, certain water soluble products and related assets, as well as higher sales than anticipated for certain products, partially offset by the build-up of certain products for increased demand. See Notes to Consolidated Financial Statements - Note 11. Inventories.

Other current assets decreased primarily due to lower value-added tax receivables for our international markets and the deferral of a prepaid tax benefit in connection with a prepayment from a related foreign entity in Belgium, partially offset by the mark-to-market adjustment of derivative instruments and the jurisdictional netting of income taxes receivable and income taxes payable.

Property, plant and equipment less accumulated depreciation increased primarily as a result of capital spending, partially offset by depreciation expense, as well as the divestiture of our medicated feed additive product portfolio, certain water soluble products and related assets. See Notes to Consolidated Financial Statements - Note 12. Property, Plant and Equipment.

Identifiable intangible assets, less accumulated amortization decreased primarily as a result of amortization expense, the divestiture of our medicated feed additive product portfolio, certain water soluble products and related assets, as well as certain asset impairment charges.

The net changes in Noncurrent deferred tax assets, Noncurrent deferred tax liabilities, Income taxes payable and Other taxes payable primarily reflect adjustments to the accrual for the income tax provision, the timing of income tax payments and the tax impact of various acquisitions and divestitures.

Other noncurrent assets increased primarily due to capitalized cloud computing arrangements implementation costs.

Accounts payable increased as a result of the timing of vendor and value-added tax payments.

Dividends payable increased as a result of an increase in the dividend rate for the first quarter 2025 dividend, which was declared on December 12, 2024.

Accrued expenses increased primarily as a result of accrued contract rebates and the timing of payments for other accrued expenses.

Accrued compensation and related items increased primarily due to the accrual of 2024 annual incentive bonuses, sales incentive bonuses and savings plan contributions to eligible employees, partially offset by the payments of 2023 annual incentive bonuses and sales incentive bonuses, as well as savings plan contributions to eligible employees.

Other current liabilities increased primarily due to collateral received related to derivative contracts, partially offset by the mark-to-market adjustment of derivative instruments.

The decrease in Operating lease liabilities reflects lease amortization and payments, partially offset by assets acquired through new lease obligations. See Notes to Consolidated Financial Statements—Note 10. Leases.

Other noncurrent liabilities decreased primarily due to the reversal of certain employee termination costs as a result of a change in strategy from our 2015 operational efficiency initiative and the divestiture of our medicated feed additive product portfolio, certain water soluble products and related assets.

Operating activities

2024 vs. 2023

Net cash provided by operating activities was $2,953 million in 2024 compared with $2,353 million in 2023. The increase in operating cash flows was primarily attributable to higher inventory build-up of certain products in the prior period for increased demand and to mitigate potential supply constraints and the timing of receipts and payments in the ordinary course of business, as well as higher net income adjusted by non-cash items.

Investing activities

2024 vs. 2023

Net cash used in investing activities was $315 million in 2024 compared with $777 million in 2023. The net cash used in investing activities for 2024 was primarily due to capital expenditures, partially offset by net proceeds on the sale of our medicated feed additive product portfolio, certain water soluble products and related assets, as well as net proceeds from derivative instrument activity. The net cash used in investing activities for 2023 was primarily due to capital expenditures and acquisitions, partially offset by net proceeds on the sale of a majority interest in our pet insurance business and net proceeds from derivative instrument activity.

Financing activities

2024 vs. 2023

Net cash used in financing activities was $2,660 million in 2024 compared with $3,109 million in 2023. The net cash used in financing activities for 2024 was primarily attributable to the purchase of treasury shares and related payment of excise taxes, the payment of dividends and taxes paid on withholding shares, partially offset by proceeds in connection with the issuance of common stock under our equity incentive plan. The net cash used in financing activities for 2023 was primarily attributable to the repayment of the $1.35 billion aggregate principal amount of our 2013 senior notes due 2023 in February 2023, the purchase of treasury shares, the payment of dividends and taxes paid on withholding shares, partially offset by proceeds in connection with the issuance of common stock under our equity incentive plan.

Analysis of financial condition, liquidity and capital resources

While we believe our cash and cash equivalents on hand, our operating cash flows and our existing financing arrangements will be sufficient to support our cash needs for the next twelve months and beyond, this may be subject to the environment in which we operate. Risks to our meeting future funding requirements are described in Global economic conditions below.

Selected measures of liquidity and capital resources

Certain relevant measures of our liquidity and capital resources follow:

Cash and cash equivalents$1,987$2,041
Accounts receivable, net(a)1,3161,304

Working capital2,5744,454
Ratio of current assets to current liabilities1.75:13.36:1

(a)    Accounts receivable are usually collected over a period of 45 to 75 days. For the years ended December 31, 2024 and 2023, the number of days that accounts receivables were outstanding have remained within this range. We regularly monitor our accounts receivable for collectability, particularly in markets where economic conditions remain uncertain. We believe that our allowance for doubtful accounts is appropriate. Our assessment is based on such factors as past due aging, historical and expected collection patterns, the financial condition of our customers, the robust nature of our credit and collection practices and the economic environment.

For additional information about the sources and uses of our funds, see the Analysis of the Consolidated Balance Sheets and Analysis of the Consolidated Statements of Cash Flows sections of this MD&A.

Credit facility and other lines of credit

In December 2022, we entered into an amended and restated revolving credit agreement with a syndicate of banks providing for a multi-year $1.0 billion senior unsecured revolving credit facility (the credit facility), which expires in December 2027. Subject to certain conditions, we have the right to increase the credit facility up to $1.5 billion. The credit facility contains a financial covenant requiring us to not exceed a maximum total leverage ratio (the ratio of consolidated net debt as of the end of the period to consolidated Earnings Before Interest, Income Taxes, Depreciation and Amortization (EBITDA) for such period) of 3.50:1. Upon entering into a material acquisition, the maximum total leverage ratio increases to 4.00:1, and extends until the fourth full consecutive fiscal quarter ended immediately following the consummation of a material acquisition. In addition, the credit facility contains other customary covenants.

We were in compliance with all financial covenants as of December 31, 2024 and December 31, 2023. There were no amounts drawn under the credit facility as of December 31, 2024 or December 31, 2023.

We have additional lines of credit and other credit arrangements with a group of banks and other financial intermediaries for general corporate purposes. We maintain cash and cash equivalent balances in excess of our outstanding short-term borrowings. As of December 31, 2024, we had access to $50 million of lines of credit which expire at various times and are generally renewed annually. There were no borrowings outstanding related to these facilities as of December 31, 2024 and $3 million of borrowings outstanding related to these facilities as of December 31, 2023.

Domestic and international short-term funds

Many of our operations are conducted outside the U.S. The amount of funds held in the U.S. will fluctuate due to the timing of receipts and payments in the ordinary course of business and due to other reasons, such as business development activities. As part of our ongoing liquidity assessments, we regularly monitor the mix of U.S. and international cash flows (both inflows and outflows). Actual repatriation of overseas funds can result in additional U.S. and local income taxes, such as U.S. state income taxes, local withholding taxes, and taxes on currency gains and losses. See Notes to Consolidated Financial Statements—Note 8. Tax Matters.

Global economic conditions

Global financial markets may be impacted by macroeconomic, business and financial volatility. Challenging economic conditions in recent years have not had, nor do we anticipate that it will have, a significant impact on our liquidity. Due to our operating cash flows, financial assets, access to capital markets and available lines of credit and revolving credit agreements, we continue to believe that we have the ability to meet our liquidity needs for the foreseeable future. As markets change, we continue to monitor our liquidity position. There can be no assurance that a challenging economic environment or an economic downturn will not impact our liquidity or our ability to obtain financing in the future.

In the normal course of business, we enter into contracts and commitments that obligate us to make payments in the future. These obligations include long-term debt, including interest obligations, purchase obligations, lease commitments, other liabilities, benefit plan obligations and uncertain tax positions. See Notes to Consolidated Financial Statements—Note 9. Financial Instruments, Note 18. Commitments and Contingencies, Note 10. Leases, Note 6. Restructuring Charges and Other Costs Associated with Acquisitions and Divestitures, Note 14. Benefit Plans and Note 8. Tax Matters for further information on material cash requirements from known contractual and other obligations.

Debt securities

On November 8, 2022, we issued $1.35 billion aggregate principal amount of our senior notes (2022 senior notes), with an original issue discount of $2 million. These notes are comprised of $600 million aggregate principal amount of 5.400% senior notes due 2025 and $750 million aggregate principal amount of 5.600% senior notes due 2032. On February 1, 2023, the net proceeds were used to redeem in full, upon maturity, the $1.35 billion aggregate principal amount of our 3.250% 2013 senior notes due 2023.

Our senior notes are governed by an indenture and supplemental indentures (collectively, the indenture) between us and Deutsche Bank Trust Company Americas, as trustee. The indenture contains certain covenants, including limitations on our and certain of our subsidiaries' ability to incur liens or engage in sale lease-back transactions. The indenture also contains restrictions on our ability to consolidate, merge or sell substantially all of our assets. In addition, the indenture contains other customary terms, including certain events of default, upon the occurrence of which, the senior notes may be declared immediately due and payable.

Pursuant to the indenture, we are able to redeem the senior notes of any series, in whole or in part, at any time by paying a “make whole” premium, plus accrued and unpaid interest to, but excluding, the date of redemption. Upon the occurrence of a change of control of us and a downgrade of the senior notes below an investment grade rating by each of Moody's Investors Service, Inc. and Standard & Poor's Ratings Services, we are, in certain circumstances, required to make an offer to repurchase all of the outstanding senior notes at a price equal to 101% of the aggregate principal amount of the senior notes together with accrued and unpaid interest to, but excluding, the date of repurchase.

Our outstanding debt securities are as follows:

Pension obligations

As part of the separation from Pfizer, Pfizer transferred to us the net pension obligations associated with certain international defined benefit plans. We expect to contribute a total of $6 million to these plans in 2025.

As of December 31, 2024, the supplemental savings plan liability was $48 million.

For additional information, see Notes to Consolidated Financial Statements— Note 14. Benefit Plans.

Share repurchase program

In December 2021, our Board of Directors authorized a $3.5 billion multi-year share repurchase program. This program was completed as of December 31, 2024. In August 2024, our Board of Directors authorized a new multi-year share repurchase program of up to $6 billion of our outstanding common stock. As of December 31, 2024, there was $5.6 billion remaining under this authorization. Purchases of Zoetis shares may be made at the discretion of management, depending on market conditions and business needs. Share repurchases may be executed through various

48 |

means, including open market or privately negotiated transactions. During 2024, 10.4 million shares were repurchased for $1.8 billion, which excludes a $17 million accrual for excise tax on net share repurchases.

Off-balance sheet arrangements

In the ordinary course of business and in connection with the sale of assets and businesses, we may indemnify our counterparties against certain liabilities that may arise in connection with a transaction or that are related to activities prior to a transaction. These indemnifications typically pertain to environmental, tax, employee and/or product-related matters, and patent-infringement claims. If the indemnified party were to make a successful claim pursuant to the terms of the indemnification, we would be required to reimburse the loss. These indemnifications are generally subject to threshold amounts, specified claim periods and other restrictions and limitations. Historically, we have not paid significant amounts under these provisions and, as of December 31, 2024 and 2023, recorded amounts for the estimated fair value of these indemnifications are not material.

New accounting standards

Overview of our business

We are a global leader in the animal health industry, focused on the discovery, development, manufacture and commercialization of medicines, vaccines, diagnostic products and services, biodevices, genetic tests and precision animal health. For over 70 years, we have been innovating ways to predict, prevent, detect, and treat animal illness, and continue to stand by those raising and caring for animals worldwide - from veterinarians and pet owners to livestock farmers and ranchers.

We manage our operations through two geographic operating segments: the United States (U.S.) and International. Within each of these operating segments, we offer a diversified product portfolio for both companion animals and livestock customers in order to capitalize on local and regional trends and customer needs. See Notes to Consolidated Financial Statements—Note 19. Segment Information.

We directly market our products to veterinarians and livestock producers located in approximately 45 countries across North America, Europe, Africa, Asia, Australia and South America, and are a market leader in nearly all of the major regions in which we operate. Through our efforts to establish an early and direct presence in many emerging markets, such as Brazil, Chile, China and Mexico, we believe we are one of the largest animal health medicines and vaccines businesses as measured by revenue across emerging markets as a whole. In markets where we do not have a direct commercial presence, we generally contract with distributors that provide logistics and sales and marketing support for our products.

We believe our investments in one of the industry’s largest sales organizations, including our extensive network of technical and veterinary operations specialists, our high-quality manufacturing and reliability of supply, and our long track record of developing products that meet customer needs, has led to enduring and valued relationships with our customers. Our research and development (R&D) efforts enable us to deliver innovative products to address unmet needs and evolve our product lines so that they remain relevant for our customers.

We have approximately 300 product lines that we sell in over 100 countries for the prediction, prevention, detection and treatment of diseases and conditions that affect various companion animal and livestock species. The diversity of our product portfolio and our global operations provides stability to our overall business. For instance, in livestock, impacts on our revenue that may result from disease outbreaks or weather conditions in a particular market or region are often offset by increased sales in other regions from exports and other species as consumers shift to other animal proteins.

A summary of our 2023 performance compared with the comparable 2022 and 2021 periods follows:

Our operating environment

Industry

The animal health industry, which focuses on both companion animals and livestock, is a growing industry that impacts billions of people worldwide. The primary companion animal species are dogs, cats and horses. Factors influencing growth in demand for companion animal medicines, vaccines and diagnostics include:

•economic development and related increases in disposable income, particularly in many emerging markets;

•increasing pet ownership and pet owners’ commitment to the health and well-being of their pets;

•companion animals living longer;

•increasing medical treatment of companion animals; and

•advances in companion animal medicines, vaccines and diagnostics.

The primary livestock species for the production of animal protein are cattle (both beef and dairy), swine, poultry, fish and sheep. Livestock health

and production are essential to meeting the growing demand for animal protein of a global population. Factors influencing growth in demand for livestock medicines and vaccines include:

•human population growth and increasing standards of living, particularly in many emerging markets;

•increasing demand for improved nutrition, particularly animal protein;

•natural resource constraints, such as scarcity of arable land, fresh water and increased competition for cultivated land, resulting in fewer resources that will be available to meet an increasing demand for animal protein;

•increasing urbanization; and

•increased focus on food safety and food security.

The overall economic environment

In addition to industry-specific factors, we, like other businesses, face challenges related to global economic conditions, an economic downturn and high inflation. Growth in both the livestock and companion animal sectors is driven by overall economic development and related growth, particularly in many emerging markets. In the past, certain of our customers and suppliers have been affected directly by shortages in veterinary healthcare workers and economic downturns or inflation, which decreased the demand for our products and, in some cases, hindered our ability to collect amounts due from customers.

The cost of medicines and vaccines to our livestock producer customers is small relative to other production costs, including feed, and the use of these products is intended to improve livestock producers’ economic outcomes. As a result, demand for our products has historically been more stable than demand for other production inputs. Similarly, industry sources have reported that pet owners indicated a preference for reducing spending on other aspects of their lifestyle, including entertainment, clothing and household goods, before reducing spending on pet care. Each of these factors, plus our broad and innovative portfolio, contributes to our ability to incorporate inflationary challenges into our product pricing and mitigate the impact on our results. While these factors have mitigated the impact of prior downturns in the global economy, economic challenges, including an economic downturn and inflation, could increase cost sensitivity among our customers, which may result in reduced demand for our products, which could have a material adverse effect on our operating results and financial condition.

Competition

The animal health industry is highly competitive. Although our business is the largest based on revenue in the animal health industry (which includes medicines, vaccines and diagnostics), we face competition in the regions in which we operate. Principal methods of competition vary depending on the particular region, species, product category or individual product. Some of these methods include new product development, quality, price, service and promotion to veterinary professionals, pet owners and livestock producers. Our competitors include standalone animal health businesses and the animal health businesses of large pharmaceutical companies. In recent years, there has been an increase in consolidation in the animal health industry. There are also many start-up companies working in the animal health area. In addition to competition from established market participants, there could be new entrants to the animal health medicines, vaccines and diagnostics industry in the future. We also compete with companies that produce generic products, following our products’ loss of exclusivity in a given market. For example, Draxxin currently competes with generic products in key markets including the U.S., Europe, Canada, Mexico and Australia. Since 2021, the first year of generic competition, sales of Draxxin declined by 47% in the U.S., its largest market, and additional declines are expected in subsequent years. For more information regarding the generic competition we expect to encounter as patents on certain of our key products expire, see Item 1. Business – Intellectual Property.

Manufacturing and supply

In order to sell our products, we must be able to produce and ship our products in sufficient quantities. Many of our products involve complex manufacturing processes and are sole-sourced from certain manufacturing sites. Minor deviations in our manufacturing or logistical processes, such as temperature excursions or improper package sealing, could result in delays, inventory shortages, unanticipated costs, product recalls, product liability and/or regulatory action. In addition, a number of factors could cause production interruptions that could result in launch delays, inventory shortages, recalls, unanticipated costs or issues with our supply agreements with third parties.

Our manufacturing network may be unable to meet the demand for our products or we may have excess capacity if demand for our products changes. The unpredictability of a product's regulatory or commercial success or failure, the lead time necessary to construct highly technical and complex manufacturing sites, and shifting customer demand increase the potential for capacity imbalances.

Product development initiatives

Our future success depends on both our existing product portfolio and our pipeline of new products, including new products that we may develop through joint ventures and products that we are able to obtain through license or acquisition. We believe we are an industry leader in animal health R&D, with a track record of generating new products and product lifecycle innovation. The majority of our R&D programs focus on new products. However, we also continue to invest in lifecycle innovation, which is defined as R&D programs that leverage existing animal health products by adding new species or claims, achieving approvals in new markets or creating new combinations and reformulations. In addition to traditional medicines and vaccines, we develop products across additional categories to address the needs of veterinarians and producers to predict, prevent, detect and treat conditions in both companion animals and livestock, including products and services in diagnostics, genetics, precision animal health and digital and data analytics.

Changing distribution channels for companion animal products

In most markets, companion animal owners typically purchase their animal health products directly from veterinarians. However, in the U.S. and certain other markets, companion animal owners increasingly have the option to purchase animal health products from sources other than veterinarians, such as internet-based retailers, “big-box” retail stores or other over-the-counter distribution channels. This trend has been demonstrated by the shift away from the veterinarian distribution channel in the sale of flea and tick products in recent years and has been accelerated by the increase in e-commerce during the COVID-19 pandemic. We believe the ability of pet owners to purchase our products online and from retail

33 |

Table of Contents

stores may increase pet owner compliance and result in increased sales. However, over time, we may be unable to sustain our current margins due to the increased purchasing power of such retailers as compared to traditional veterinary practices.

In addition, this trend could negatively impact the sales of products we primarily sell through the veterinarian distribution channel, as any decrease in visits to veterinarians by companion animal owners could reduce our market share and sales of such products. A reduction in the number of pet owners who purchase our products directly from their veterinarian could also lead to increased use of generic alternatives to our products or the increased substitution of our products with other animal health products or human health products if such other products are deemed to be lower-cost alternatives.

Perceptions of product quality, safety and reliability

We believe that animal health customers value high-quality manufacturing and reliability of supply. The importance of quality and safety concerns to pet owners, veterinarians and livestock producers also contributes to animal health brand loyalty, which often continues after the loss of patent-based and regulatory exclusivity. We depend on positive perceptions of the safety and quality of our products by our customers, veterinarians and end-users.

In addition, negative beliefs about animal health products generally could impact demand for our products. For example, the issue of the potential transfer of increased antibacterial resistance in bacteria from food-producing animals to human pathogens, and the causality of that transfer, continue to be the subject of global scientific and regulatory discussion. Antibacterials refer to small molecules that can be used to treat or prevent bacterial infections and are a sub-categorization of the products that make up our anti-infectives and medicated feed additives portfolios. In some countries, this issue has led to government restrictions and bans on the use of specific antibacterials in some food-producing animals, regardless of the route of administration (in feed or injectable). These restrictions are more prevalent in countries where animal protein is plentiful and governments are willing to take action even when there is scientific uncertainty. In addition, consumer preferences in some markets have impacted the use of antibacterials in food producing animals. Such restrictions and consumer preferences in some cases may negatively impact sales of our antibacterial products, but in other instances may increase sales of our products that can be used as antibacterial alternatives. Our total revenue attributable to antibacterials for livestock was less than $950 million for the year ended December 31, 2023.

Similarly, concerns regarding greenhouse gas emissions and other potential environmental impacts of livestock production have led to some consumers opting to limit or avoid consuming animal products. However, we believe the impact of this trend is limited as the livestock industry is still expected to continue to grow in order to feed a growing global population.

Disease Outbreaks

Sales of our livestock products have in the past, and may in the future be, adversely affected by the outbreak of disease carried by animals. Outbreaks of disease may reduce regional or global sales of particular animal-derived food products or result in reduced exports of such products, either due to heightened export restrictions or import prohibitions, which may reduce demand for our products. Also, the outbreak of any highly contagious disease near our main production sites could require us to immediately halt production of our products at such sites or force us to incur substantial expenses in procuring raw materials or products elsewhere. Alternatively, sales of products that treat specific disease outbreaks may increase.

Weather conditions, climate change and the availability of natural resources

The animal health industry and demand for many of our animal health products in a particular region are affected by weather conditions, as usage of our products follows varying weather patterns and weather-related pressures from pests, such as ticks. As a result, we may experience regional and seasonal fluctuations in our results of operations.

In addition, veterinary hospitals and practitioners depend on visits from and access to the animals under their care. Veterinarians’ patient volume and ability to operate could be adversely affected if they experience prolonged snow, ice or other severe weather conditions, particularly in regions not accustomed to sustained inclement weather. Furthermore, weather conditions, including excessive cold or heat, natural disasters and other events, could negatively impact our livestock customers by impairing the health or growth of their animals or the production or availability of feed, as well as disrupting their normal operations. For example, livestock producers depend on the availability of natural resources, including large supplies of fresh water. Their animals’ health and their ability to operate could be adversely affected if they experience a shortage of fresh water due to human population growth, climate change or floods, droughts or other weather conditions. In the event of adverse weather conditions, climate-change related impacts or a shortage of fresh water, veterinarians and livestock producers may purchase less of our products.

For example, drought conditions could negatively impact, among other things, the supply of corn and the availability of grazing pastures. A decrease in harvested corn results in higher corn prices, which could negatively impact the profitability of livestock producers of cattle, pork and poultry. Higher corn prices and reduced availability of grazing pastures contribute to reductions in herd or flock sizes that in turn result in less spending on animal health products. As such, a prolonged drought could have an adverse impact on our operating results and financial condition.

Adverse weather conditions, natural disasters and climate change may also impact the aquaculture business. Changes in water temperatures could affect the timing of reproduction and growth of various fish species, as well as trigger the outbreak of certain waterborne diseases.

Foreign exchange rates

Significant portions of our revenue and costs are exposed to changes in foreign exchange rates. Our products are sold in more than 100 countries and, as a result, our revenue is influenced by changes in foreign exchange rates. For the year ended December 31, 2023, approximately 43% of our revenue was denominated in foreign currencies. We seek to manage our foreign exchange risk, in part, through operational means, including managing same-currency revenue in relation to same-currency costs and same-currency assets in relation to same-currency liabilities. As we operate in multiple foreign currencies, including the Australian dollar, Brazilian real, British pound, Canadian dollar, Chinese renminbi, euro and other currencies, changes in those currencies relative to the U.S. dollar will impact our revenue, cost of goods and expenses, and consequently, net income. Exchange rate fluctuations may also have an impact beyond our reported financial results and directly impact operations. These fluctuations may affect the ability to buy and sell our goods and services between markets impacted by significant exchange rate variances. For the year ended December 31, 2023, approximately 57% of our total revenue was in U.S. dollars. Our year-over-year total revenue growth was unfavorably impacted by 1% from changes in foreign currency values relative to the U.S. dollar.

Components of revenue and costs and expenses

Our revenue, costs and expenses are reported for the year ended December 31 for each year presented, except for operations outside the U.S., for which the financial information is included in our consolidated financial statements for the fiscal year ended November 30 for each year presented.

Revenue

Our revenue is primarily derived from our diversified product portfolio of medicines, vaccines and diagnostic products and services used to treat and protect companion animals and livestock. Generally, our products are promoted to veterinarians and livestock producers by our sales organization which includes sales representatives and technical and veterinary operations specialists, and then sold directly by us or through distributors, retailers or e-commerce outlets. The depth of our product portfolio enables us to address the varying needs of customers in different species and geographies. In 2023, our two top-selling products and product lines, Simparica/Simparica Trio and Apoquel/Apoquel Chewable, each contributed approximately 13% and 10% of our revenue, respectively, and combined with our next three top-selling products and product lines, Cytopoint, Revolution/Revolution Plus/Stronghold and ceftiofur line, these five products and product lines contributed approximately 37% of our revenue. Our ten top-selling products and product lines contributed 49% of our revenue. For additional information regarding our products, including descriptions of our product lines that each represented approximately 1% or more of our revenue in 2023, see Item 1. Business—Products.

Costs and expenses

Costs of sales consist primarily of cost of materials, facilities and other infrastructure used to manufacture our medicine and vaccine products, as well as costs to operate our reference labs and royalty expenses associated with the intellectual property of our products, when relevant.

Selling, general and administrative (SG&A) expenses consist of, among other things, the internal and external costs of marketing, promotion, advertising and shipping and handling as well as certain costs related to business technology, facilities, legal, finance, human resources, business development, public affairs and procurement.

Research and development (R&D) expenses consist primarily of project costs specific to new product R&D and product lifecycle innovation, overhead costs associated with R&D operations and investments that support local market clinical trials for approved indications and expenses related to regulatory approvals for our products. We do not disaggregate R&D expenses by research stage or by therapeutic area for purposes of managing our business.

Amortization of intangible assets consists primarily of the amortization expense for identifiable finite-lived intangible assets that have been acquired through business combinations. These assets consist of, but are not limited to, developed technology, brands and trademarks.

Restructuring charges and certain acquisition-related costs consist of all restructuring charges (those associated with cost reduction/productivity initiatives and those associated with acquisition activity), as well as costs associated with acquiring and integrating businesses. Restructuring charges

Table of Contents

are associated with employees, assets and activities that will not continue in the company. Acquisition-related costs are associated with acquiring and integrating acquired businesses and may include transaction costs and expenditures for consulting and the integration of systems and processes.

Other (income)/deductions—net consists of various items, primarily net (gains)/losses on business sales and divestitures, as well as asset disposals, interest income, royalty-related income, foreign exchange translation (gains)/losses and certain asset impairment charges.

Significant accounting policies and application of critical accounting estimates

In presenting our financial statements in conformity with U.S. GAAP, we are required to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenue, costs and expenses and related disclosures. For a description of our significant accounting policies, see Notes to Consolidated Financial Statements—Note 3. Significant Accounting Policies.

We believe that the following accounting policies are critical to an understanding of our consolidated financial statements as they require the application of the most difficult, subjective and complex judgments and, therefore, could have the greatest impact on our financial statements: (i) fair value; (ii) revenue; (iii) asset impairment reviews; and (iv) contingencies.

Below are some of our more critical accounting estimates. See also Notes to Consolidated Financial Statements—Note 3. Significant Accounting Policies: Estimates and Assumptions for a discussion about the risks associated with estimates and assumptions.

Fair value

For a discussion about the application of fair value to our long-term debt and financial instruments, see Notes to Consolidated Financial Statements—Note 9. Financial Instruments.

For a discussion about the application of fair value to our business combinations, see Notes to Consolidated Financial Statements—Note 3. Significant Accounting Policies: Fair Value.

For a discussion about the application of fair value to our asset impairment reviews, see Asset impairment reviews below.

Revenue

Our gross product revenue is subject to deductions that are generally estimated and recorded in the same period that the revenue is recognized and primarily represents sales returns and revenue incentives. For example:

•for sales returns, we perform calculations in each market that incorporate the following, as appropriate: local returns policies and practices; returns as a percentage of revenue; an understanding of the reasons for past returns; estimated shelf life by product; an estimate of the amount of time between shipment and return or lag time; and any other factors that could impact the estimate of future returns, product recalls, discontinuation of products or a changing competitive environment; and

•for revenue incentives, we use our historical experience with similar incentives programs to estimate the impact of such programs on revenue.

If any of our ratios, factors, assessments, experiences or judgments are not indicative or accurate predictors of our future experience, our results could be materially affected. Although the amounts recorded for these revenue deductions are dependent on estimates and assumptions, historically our adjustments to actual results have not been material. The sensitivity of our estimates can vary by program, type of customer and geographic location.

Amounts recorded for revenue deductions can result from a complex series of judgments about future events and uncertainties and can rely on estimates and assumptions. For further information about the risks associated with estimates and assumptions, see Notes to Consolidated Financial Statements—Note 3. Significant Accounting Policies: Estimates and Assumptions.

Asset impairment reviews

We review all of our long-lived assets for impairment indicators throughout the year and we perform detailed testing whenever impairment indicators are present. In addition, we perform impairment testing for goodwill and indefinite-lived intangible assets at least annually. When necessary, we record charges for impairments of long-lived assets for the amount by which the fair value is less than the carrying value of these assets.

Our impairment review processes are described below and in Notes to Consolidated Financial Statements—Note 3. Significant Accounting Policies: Amortization of Intangible Assets, Depreciation and Certain Long-Lived Assets and, for deferred tax assets, in Note 3. Significant Accounting Policies: Deferred Tax Assets and Liabilities and Income Tax Contingencies.

Examples of events or circumstances that may be indicative of impairment include:

•a significant adverse change in the extent or manner in which an asset is used. For example, restrictions imposed by the regulatory authorities could affect our ability to manufacture or sell a product; and

•a projection or forecast that demonstrates losses or reduced profits associated with an asset. This could result, for example, from the introduction of a competitor’s product that results in a significant loss of market share or the inability to achieve the previously projected revenue growth, or from the lack of acceptance of a product by customers.

For finite-lived identifiable intangible assets, such as developed technology rights, and for other long-lived assets, such as property, plant and equipment, whenever impairment indicators are present, we calculate the undiscounted value of the projected cash flows associated with the asset, or asset group, and compare this estimated amount to the carrying amount. If the carrying amount is found to be greater, we record an impairment loss for the excess of book value over fair value. In addition, in all cases of an impairment review, we re-evaluate the remaining useful lives of the assets and modify them, as appropriate.

Our impairment reviews of most of our long-lived assets depend on the determination of fair value, as defined by U.S. GAAP, and these judgments can materially impact our results of operations. A single estimate of fair value can result from a complex series of judgments about future events and

Table of Contents

uncertainties and can rely on estimates and assumptions. For information about the risks associated with estimates and assumptions, see Notes to Consolidated Financial Statements—Note 3. Significant Accounting Policies: Estimates and Assumptions.

Intangible assets other than goodwill

We test indefinite-lived intangible assets for impairment at least annually, or more frequently if impairment indicators exist, by first assessing qualitative factors to determine whether it is more likely than not that the fair value of the indefinite-lived intangible asset is less than its carrying amount. If we conclude it is more likely than not that the fair value is less than the carrying amount, a quantitative test that compares the fair value of the indefinite-lived intangible asset with its carrying value is performed. If the fair value is less than the carrying amount, an impairment loss is recognized. Impairments of identifiable intangible assets other than goodwill, are recorded in Restructuring charges and certain acquisition-related costs and Other (income)/deductions—net, as applicable. We did not have any material intangible asset impairment charges for the years ended December 31, 2023, 2022 and 2021.

When we are required to determine the fair value of intangible assets other than goodwill, we use an income approach, specifically the multi-period excess earnings method, also known as the discounted cash flow method. We start with a forecast of all the expected net cash flows associated with the asset, which includes the application of a terminal value for indefinite-lived assets, and then we apply an asset-specific discount rate to arrive at a net present value amount. Some of the more significant estimates and assumptions inherent in this approach include: the amount and timing of the projected net cash flows, which includes the expected impact of competitive, legal and/or regulatory forces on the projections, the impact of technological risk associated with IPR&D assets, as well as the selection of a long-term growth rate; the discount rate, which seeks to reflect the risks inherent in the projected cash flows; foreign currency fluctuations; and the effective tax rate, which seeks to incorporate the geographic diversity of the projected cash flows.

While all identifiable intangible assets can be impacted by events and thus lead to impairment, in general, identifiable intangible assets that are at the highest risk of impairment include IPR&D assets ($141 million as of December 31, 2023). IPR&D assets are higher-risk assets given the uncertain nature of R&D activity.

For a description of our accounting policy, see Notes to Consolidated Financial Statements—Note 3. Significant Accounting Policies: Amortization of Intangible Assets, Depreciation and Certain Long-Lived Assets.

Goodwill

Goodwill represents the excess of the consideration transferred over the fair value of net assets of businesses purchased and is assigned to reporting units. We test goodwill for impairment on at least an annual basis, or more frequently if necessary, either by assessing qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount or by performing a periodic quantitative assessment.

Factors considered in the qualitative assessment include general macroeconomic conditions, conditions specific to the industry and market, cost factors which could have a significant effect on earnings or cash flows, the overall financial performance of the reporting unit and whether there have been sustained declines in our share price. Additionally, we evaluate the extent to which the fair value exceeded the carrying value of the reporting unit at the date of the last quantitative assessment performed.

When performing a quantitative assessment to test for goodwill impairment we utilize the income approach, which is forward-looking, and relies primarily on internal forecasts. Within the income approach, the method that we use is the discounted cash flow method. We start with a forecast of all the expected net cash flows associated with the reporting unit, which includes the application of a terminal value, and then apply a reporting unit-specific discount rate to arrive at a net present value. Some of the more significant estimates and assumptions inherent in this approach include: the amount and timing of the projected net cash flows, which includes the expected impact of technological risk and competitive, legal and/or regulatory forces on the projections, as well as the selection of a long-term growth rate; the discount rate, which seeks to reflect the various risks inherent in the projected cash flows; and the effective tax rate, which seeks to incorporate the geographic diversity of the projected cash flows.

We test goodwill for impairment on at least an annual basis, or more frequently if necessary, either by assessing qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount or by performing a periodic quantitative assessment. In 2023, we performed a qualitative impairment assessment as of September 30, 2023, which did not result in the impairment of goodwill associated with any of our reporting units. In 2022, we performed a periodic quantitative impairment assessment as of September 30, 2022, which did not result in the impairment of goodwill associated with any of our reporting units.

For all of our reporting units, there are a number of future events and factors that may impact future results and that could potentially have an impact on the outcome of subsequent goodwill impairment testing. For a list of these factors, see Forward-looking statements and factors that may affect future results.

For a description of our accounting policy, see Notes to Consolidated Financial Statements—Note 3. Significant Accounting Policies: Amortization of Intangible Assets, Depreciation and Certain Long-Lived Assets.

Contingencies

For a discussion about income tax contingencies, see Notes to Consolidated Financial Statements—Note 8D. Tax Matters: Tax Contingencies.

For a discussion about legal contingencies, guarantees and indemnifications, see Notes to Consolidated Financial Statement—Note 18. Commitments and Contingencies.

Non-GAAP financial measures

We report information in accordance with U.S. generally accepted accounting principles (GAAP). Management also measures performance using non-GAAP financial measures that may exclude certain amounts from the most directly comparable GAAP measure. Despite the importance of these measures to management in goal setting and performance measurement, non-GAAP financial measures have no standardized meaning prescribed by U.S. GAAP and, therefore, have limits in their usefulness to investors and may not be comparable to the calculation of similar measures of other

37 |

Table of Contents

companies. We present certain identified non-GAAP measures solely to provide investors with useful information to more fully understand how management assesses performance.

Operational Growth

We believe that it is important to not only understand overall revenue and earnings growth, but also “operational growth.” Operational growth is a non-GAAP financial measure defined as revenue or earnings growth excluding the impact of foreign exchange. This measure provides information on the change in revenue and earnings as if foreign currency exchange rates had not changed between the current and prior periods to facilitate a period-to-period comparison. We believe this non-GAAP measure provides a useful comparison to previous periods for the company and investors, but should not be viewed as a substitute for U.S. GAAP reported growth.

Adjusted Net Income and Adjusted Earnings Per Share

Adjusted net income and the corresponding adjusted earnings per share (EPS) are non-GAAP financial measures of performance used by management. We believe these financial measures are useful supplemental information to investors when considered together with our U.S. GAAP financial measures. We report adjusted net income to portray the results of our major operations, and the discovery, development, manufacture and commercialization of our products, prior to considering certain income statement elements. We define adjusted net income and adjusted EPS as net income attributable to Zoetis and EPS before the impact of purchase accounting adjustments, acquisition-related costs and certain significant items.

We recognize that, as an internal measure of performance, the adjusted net income and adjusted EPS measures have limitations, and we do not restrict our performance management process solely to these metrics. A limitation of the adjusted net income and adjusted EPS measures is that they provide a view of our operations without including all events during a period, such as the effects of an acquisition or amortization of purchased intangibles, and do not provide a comparable view of our performance to other companies. The adjusted net income and adjusted EPS measures are not, and should not be viewed as, a substitute for U.S. GAAP reported net income attributable to Zoetis and reported EPS. See the Adjusted Net Income section below for more information.

The income tax provision in the Consolidated Statements of Income includes tax costs and benefits, such as uncertain tax positions, repatriation decisions and audit settlements, among others.

2023 vs. 2022

Our effective tax rate was 20.3% for 2023, compared with 20.5% for 2022. The lower effective tax rate for 2023 was primarily attributable to a higher benefit in the U.S. related to foreign-derived intangible income, a more favorable jurisdictional mix of earnings (which includes the impact of the location of earnings and repatriation costs), partially offset by a higher net discrete tax expense in 2023, mainly related to changes to prior years' tax positions. Jurisdictional mix of earnings can vary depending on repatriation decisions, operating fluctuations in the normal course of business and the impact of non-deductible items and non-taxable items.

2023 vs. 2022

U.S. operating segment

U.S. segment revenue increased by $242 million, or 6%, in 2023 compared with 2022, of which $188 million resulted from growth in companion animal products and $54 million growth in livestock products.

41 |

Table of Contents

•Companion animal revenue growth was primarily due to our mAb products for OA pain, Librela and Solensia, as well as increased sales of key dermatology, small animal parasiticides, small animal vaccines and small animal diagnostics, partially offset by lower sales of anti-infective products. Strong growth in the second, third and fourth quarters was partially offset by the first quarter impacts of distributor de-stocking across the portfolio, as well as purchases in the fourth quarter of 2022 ahead of expected price increases and promotional activities.

•Livestock revenue growth was due to cattle and poultry, partially offset by a decline in swine. Sales of cattle products grew due to increased sales of cattle implants, higher volume of anti-infective products and improved supply of key products. Sales of products in our poultry portfolio grew due to increases in vaccines, medicated feed additives and biodevices. Sales of swine products declined due to decreased disease prevalence.

U.S. segment earnings increased by $100 million, or 4%, in 2023 compared with 2022, primarily due to higher revenue, partially offset by higher cost of sales, operating expense growth and certain asset impairment charges related to acquired intangible assets.

International operating segment

International segment revenue increased by $230 million, or 6%, in 2023 compared with 2022. Operational revenue growth was $346 million, or 9%, reflecting growth of $228 million in companion animal products and $118 million in livestock products.

•Companion animal operational revenue growth was primarily due to increased sales of our mAb products for OA pain, Librela and Solensia, as well as small animal parasiticides and key dermatology, partially offset by lower sales of vaccine products.

•Livestock operational revenue growth was due to increased sales of cattle, poultry, fish and sheep products. Sales of cattle products grew due to price and improved supply of key products. Sales of poultry products grew due to market growth, demand generation efforts and price in key poultry markets. Growth in our fish portfolio was primarily the result of increased sales of vaccines across key salmon markets, primarily Norway, partially offset by lower sales in Chile. Sales of sheep products grew primarily as a result of the acquisition of Jurox.

•Additionally, International segment revenue was unfavorably impacted by foreign exchange which decreased revenue by approximately $116 million, or 3%, primarily driven by fluctuations in the Argentine peso, Chinese renminbi, Australian dollar, Turkish lira and Japanese yen.

International segment earnings increased by $47 million, or 2%, in 2023 compared with 2022. Operational earnings growth was $88 million, or 4%, primarily due to higher revenue, partially offset by higher cost of sales and operating expenses.

Other business activities

Other business activities includes our Client Supply Services contract manufacturing results, our human health business and expenses associated with our dedicated veterinary medicine research and development organization, research alliances, U.S. regulatory affairs and other operations focused on the development of our products. Other R&D-related costs associated with non-U.S. market and regulatory activities are generally included in the International segment.

2023 vs. 2022

Other business activities net loss increased by $72 million, or 17%, in 2023 compared with 2022, reflecting an increase in R&D costs due to an increase in certain compensation-related costs to support innovation, an increase in operating costs and higher project investments, as well as lower earnings in our human health business, partially offset by favorable foreign exchange.

Reconciling items

Reconciling items include certain costs that are not allocated to our operating segments results, such as costs associated with the following:

•Corporate, which includes certain costs associated with information technology, facilities, legal, finance, human resources, business development, certain diagnostics costs and communications, among others. These costs also include certain compensation costs, certain procurement costs, and other miscellaneous operating expenses that are not charged to our operating segments, as well as interest income and expense;

•Certain transactions and events such as Purchase accounting adjustments, Acquisition-related activities and Certain significant items, which are defined below; and

•Other unallocated, which includes (i) certain overhead expenses associated with our global manufacturing operations not charged to our operating segments; (ii) certain costs associated with finance that specifically support our global manufacturing operations; (iii) certain supply chain and global logistics costs; and (iv) certain procurement costs.

2023 vs. 2022

Corporate expenses decreased by $31 million, or 3%, in 2023 compared with 2022, primarily associated with favorable foreign exchange, higher interest income and a settlement received from a third-party for underpayment of royalties related to prior periods, partially offset by higher compensation-related costs, investments in information technology and higher interest expense.

Other unallocated expenses decreased by $88 million, or 23%, in 2023 compared with 2022, primarily due to lower manufacturing costs and freight charges, partially offset by unfavorable foreign exchange, as well as inventory obsolescence, scrap and other charges.

Adjusted net income

General description of adjusted net income (a non-GAAP financial measure)

Adjusted net income is an alternative view of performance used by management, and we believe that investors’ understanding of our performance is enhanced by disclosing this performance measure. The adjusted net income measure is an important internal measurement for us. Additionally, we measure our overall performance on this basis in conjunction with other performance metrics. The following are examples of how the adjusted net income measure is utilized:

•senior management receives a monthly analysis of our operating results that is prepared on an adjusted net income basis;

•our annual budgets are prepared on an adjusted net income basis; and

•other goal setting and performance measurements.

Purchase accounting adjustments

Adjusted net income is calculated prior to considering certain significant purchase accounting impacts that result from business combinations and net asset acquisitions. These impacts, primarily associated with certain acquisitions, include amortization related to the increase in fair value of the acquired finite-lived intangible assets and depreciation related to the increase/decrease to fair value of the acquired fixed assets. Therefore, the adjusted net income measure includes the revenue earned upon the sale of the acquired products without considering the aforementioned significant charges.

While certain purchase accounting adjustments can occur through 20 or more years, this presentation provides an alternative view of our performance that is used by management to internally assess business performance. We believe the elimination of amortization attributable to acquired intangible assets provides management and investors an alternative view of our business results by providing a degree of parity to internally developed intangible assets for which R&D costs previously have been expensed.

A completely accurate comparison of internally developed intangible assets and acquired intangible assets cannot be achieved through adjusted net income. These components of adjusted net income are derived solely from the impact of the items listed above. We have not factored in the impact of any other differences in experience that might have occurred if we had discovered and developed those intangible assets on our own, and this approach does not intend to be representative of the results that would have occurred in those circumstances. For example, our R&D costs in total, and in the periods presented, may have been different; our speed to commercialization and resulting revenue, if any, may have been different; or our costs to manufacture may have been different. In addition, our marketing efforts may have been received differently by our customers. As such, in total, there can be no assurance that our adjusted net income amounts would have been the same as presented had we discovered and developed the acquired intangible assets.

Acquisition-related costs

Adjusted net income is calculated prior to considering transaction and integration costs associated with significant business combinations or net asset acquisitions because these costs are unique to each transaction and represent costs that were incurred to acquire and integrate certain businesses as a result of the acquisition decision. We have made no adjustments for the resulting synergies.

We believe that viewing income prior to considering these charges provides investors with a useful additional perspective because the significant costs incurred in a business combination result primarily from the need to eliminate duplicate assets, activities or employees––a natural result of acquiring a fully integrated set of activities. For this reason, we believe that the costs incurred to convert disparate systems, to close duplicative facilities or to eliminate duplicate positions (for example, in the context of a business combination) can be viewed differently from those costs incurred in the ordinary course of business.

The integration costs associated with a business combination may occur over several years, with the more significant impacts generally ending within three years of the transaction. Because of the need for certain external approvals for some actions, the span of time needed to achieve certain restructuring and integration activities can be lengthy. For example, due to the regulated nature of the animal health medicines, vaccines and diagnostic business, the closure of excess facilities can take several years, as all manufacturing changes are subject to extensive validation and testing and must be approved by the FDA and/or other regulatory authorities.

Certain significant items

Adjusted net income is calculated excluding certain significant items. Certain significant items represent substantive, unusual items that are evaluated on an individual basis. Such evaluation considers both the quantitative and the qualitative aspect of their unusual nature. Unusual, in this context, may represent items that are not part of our ongoing business; items that, either as a result of their nature or size, we would not expect to occur as part of our normal business on a regular basis; items that would be nonrecurring; or items that relate to products that we no longer sell. While not all-inclusive, examples of items that could be included as certain significant items would be costs related to a major non-acquisition-related restructuring charge and associated implementation costs for a program that is specific in nature with a defined term, such as those related to our non-acquisition-related cost-reduction and productivity initiatives; amounts related to disposals of products or facilities that do not qualify as discontinued operations as defined by U.S. GAAP; certain asset impairment charges; adjustments related to the resolution of certain tax positions; significant currency devaluation; the impact of adopting certain significant, event-driven tax legislation; or charges related to legal matters. See Notes to Consolidated Financial Statements— Note 18. Commitments and Contingencies. Our normal, ongoing defense costs or settlements of and accruals on legal matters made in the normal course of our business would not be considered certain significant items.

Reconciliation

A reconciliation of net income attributable to Zoetis, as reported under U.S. GAAP, to adjusted net income follows:

* Calculation not meaningful.

(a)    The effective tax rate on adjusted pretax income was 20.1%, 20.3% and 18.6% in 2023, 2022 and 2021, respectively.

The lower effective tax rate for 2023, compared with 2022, was primarily attributable to a higher benefit in the U.S. related to foreign-derived intangible income, a more favorable jurisdictional mix of earnings (which includes the impact of the location of earnings and repatriation costs), partially offset by a higher net discrete tax expense in 2023, mainly related to changes to prior years’ tax positions. Jurisdictional mix of earnings can vary depending on repatriation decisions, operating fluctuations in the normal course of business and the impact of non-deductible and non-taxable items.

The higher effective tax rate for 2022, compared with 2021, was attributable to a less favorable jurisdictional mix of earnings (which includes the impact of the location of earnings and repatriation costs), a lower benefit in the U.S. related to foreign-derived intangible income and lower net discrete tax benefits in 2022. Jurisdictional mix of earnings can vary depending on repatriation decisions, operating fluctuations in the normal course of business and the impact of non-deductible and non-taxable items.

A reconciliation of reported diluted earnings per share (EPS), as reported under U.S. GAAP, to non-GAAP adjusted diluted EPS follows:

Analysis of the Consolidated Statements of Comprehensive Income

Changes in other comprehensive income for the periods presented are primarily related to foreign currency translation adjustments and unrealized gains/(losses) on derivative instruments. The foreign currency translation adjustment changes result from the strengthening or weakening of the U.S. dollar as compared to the currencies in the countries in which we do business. Unrealized gains/(losses) on the changes in the fair value of derivative instruments are recorded within Accumulated other comprehensive income/(loss) and reclassified into earnings depending on the nature and purpose of the financial instrument, as described in Note 9. Financial Instruments of the Notes to Consolidated Financial Statements.

Analysis of the Consolidated Balance Sheets

For a discussion about the changes in Cash and cash equivalents, Short-term borrowings, Current portion of long-term debt and Long-term debt, net of discount and issuance costs, see “Analysis of financial condition, liquidity and capital resources” below.

Accounts Receivable, less allowance for doubtful accounts increased primarily as a result of higher net sales in the period, partially offset by the timing of customer payments.

Inventories increased primarily as a result of inventory build-up to support production for the forecasted demand of certain products, including new product launches. See Notes to Consolidated Financial Statements - Note 11. Inventories.

Other current assets increased primarily due to the recognition of the deferral of a prepaid tax benefit in connection with a prepayment from a related foreign entity in Belgium, the jurisdictional netting of income taxes receivable and income taxes payable, as well as an increase in collateral posted related to derivative contracts, partially offset by the mark-to-market adjustment of derivative instruments.

Property, plant and equipment less accumulated depreciation increased primarily as a result of capital spending, partially offset by depreciation expense. See Notes to Consolidated Financial Statements - Note 12. Property, Plant and Equipment

The net changes in Noncurrent deferred tax assets, Noncurrent deferred tax liabilities, Income taxes payable and Other taxes payable primarily reflect adjustments to the accrual for the income tax provision, the timing of income tax payments, the tax impact of various acquisitions and the impact of the remeasurement of deferred tax assets and liabilities as a result of changes in tax rates.

Other noncurrent assets increased primarily due to the retained noncontrolling investment following the sale of a majority interest in our pet insurance business, capitalized cloud computing arrangements implementation costs and the addition of a financing lease.

Dividends payable increased as a result of an increase in the dividend rate for the first quarter 2024 dividend, which was declared on December 7, 2023.

Accrued compensation and related items increased primarily due to the accrual of 2023 annual incentive bonuses, sales incentive bonuses and savings plan contributions to eligible employees, as well as the timing of the bi-weekly payroll, partially offset by the payments of 2022 annual incentive bonuses and sales incentive bonuses, as well as savings plan contributions to eligible employees.

Other noncurrent liabilities increased primarily due to the net increase in purchase price liabilities associated with acquisitions and the addition of a financing lease obligation, partially offset by the mark-to-market adjustment of derivative instruments.

Operating activities

2023 vs. 2022

Net cash provided by operating activities was $2,353 million in 2023 compared with $1,912 million in 2022. The increase in operating cash flows was primarily attributable to higher net income as adjusted by non-cash items, higher inventory build-up of certain products in the prior year period for increased demand and to mitigate potential supply constraints and the timing of receipts and payments in the ordinary course of business.

Investing activities

2023 vs. 2022

Net cash used in investing activities was $777 million in 2023 compared with $883 million in 2022. The net cash used in investing activities for 2023 was primarily due to capital expenditures and acquisitions, partially offset by net proceeds on the sale of a majority interest in our pet insurance business and net proceeds from derivative instrument activity. The net cash used in investing activities for 2022 was primarily attributable to capital expenditures and acquisitions partially offset by net proceeds from derivative instrument activity.

Financing activities

2023 vs. 2022

Net cash used in financing activities was $3,109 million in 2023 compared with $904 million in 2022. The net cash used in financing activities for 2023 was primarily attributable to the repayment at maturity of the $1.35 billion aggregate principal amount of our 2013 senior notes due 2023 in February 2023, the purchase of treasury shares, the payment of dividends and taxes paid on withholding shares, partially offset by proceeds in connection with the issuance of common stock under our equity incentive plan. The net cash used in financing activities for 2022 was primarily attributable to the purchase of treasury shares, the payment of dividends and taxes paid on withholding shares, partially offset by proceeds from the issuance of senior notes in November 2022 and proceeds in connection with the issuance of common stock under our equity incentive plan.

Analysis of financial condition, liquidity and capital resources

While we believe our cash and cash equivalents on hand, our operating cash flows and our existing financing arrangements will be sufficient to support our cash needs for the next twelve months and beyond, this may be subject to the environment in which we operate. Risks to our meeting future funding requirements are described in Global economic conditions below.

(a)    Accounts receivable are usually collected over a period of 45 to 75 days. For the years ended December 31, 2023 and 2022, the number of days that accounts receivables were outstanding have remained within this range. We regularly monitor our accounts receivable for collectability, particularly in markets where economic conditions remain uncertain. We believe that our allowance for doubtful accounts is appropriate. Our assessment is based on such factors as past due aging, historical and expected collection patterns, the financial condition of our customers, the robust nature of our credit and collection practices and the economic environment.

For additional information about the sources and uses of our funds, see the Analysis of the Consolidated Balance Sheets and Analysis of the Consolidated Statements of Cash Flows sections of this MD&A.

Credit facility and other lines of credit

In December 2022, we entered into an amended and restated revolving credit agreement with a syndicate of banks providing for a multi-year $1.0 billion senior unsecured revolving credit facility (the credit facility), which expires in December 2027. Subject to certain conditions, we have the right to increase the credit facility up to $1.5 billion. The credit facility contains a financial covenant requiring us to not exceed a maximum total leverage ratio (the ratio of consolidated net debt as of the end of the period to consolidated Earnings Before Interest, Income Taxes, Depreciation and Amortization (EBITDA) for such period) of 3.50:1. Upon entering into a material acquisition, the maximum total leverage ratio increases to 4.00:1, and extends until the fourth full consecutive fiscal quarter ended immediately following the consummation of a material acquisition. In addition, the credit facility contains other customary covenants.

We were in compliance with all financial covenants as of December 31, 2023 and December 31, 2022. There were no amounts drawn under the credit facility as of December 31, 2023 or December 31, 2022.

We have additional lines of credit and other credit arrangements with a group of banks and other financial intermediaries for general corporate purposes. We maintain cash and cash equivalent balances in excess of our outstanding short-term borrowings. As of December 31, 2023, we had access to $56 million of lines of credit which expire at various times and are generally renewed annually. There were $3 million of borrowings outstanding related to these facilities as of December 31, 2023 and $2 million borrowings outstanding related to these facilities as of December 31, 2022.

Domestic and international short-term funds

Many of our operations are conducted outside the U.S. The amount of funds held in the U.S. will fluctuate due to the timing of receipts and payments in the ordinary course of business and due to other reasons, such as business development activities. As part of our ongoing liquidity assessments, we regularly monitor the mix of U.S. and international cash flows (both inflows and outflows). Actual repatriation of overseas funds can result in additional U.S. and local income taxes, such as U.S. state income taxes, local withholding taxes, and taxes on currency gains and losses. See Notes to Consolidated Financial Statements—Note 8. Tax Matters.

Global economic conditions

Challenging economic conditions in recent years have not had, nor do we anticipate that it will have, a significant impact on our liquidity. Due to our operating cash flows, financial assets, access to capital markets and available lines of credit and revolving credit agreements, we continue to believe that we have the ability to meet our liquidity needs for the foreseeable future. As markets change, we continue to monitor our liquidity position. There can be no assurance that a challenging economic environment or an economic downturn would not impact our ability to obtain financing in the future.

Contractual obligations

In the normal course of business, we enter into contracts and commitments that obligate us to make payments in the future. These obligations include long-term debt, including interest obligations, purchase obligations, lease commitments, other liabilities, benefit plan obligations and uncertain tax positions. See Notes to Consolidated Financial Statements—Note 9. Financial Instruments, Note 18. Commitments and Contingencies, Note 10. Leases, Note 6. Restructuring Charges and Other Costs Associated with Acquisitions, Cost-Reduction and Productivity Initiatives, Note 14. Benefit Plans and Note 8. Tax Matters for further information on material cash requirements from known contractual and other obligations.

Debt securities

On November 8, 2022, we issued $1.35 billion aggregate principal amount of our senior notes (2022 senior notes), with an original issue discount of $2 million. These notes are comprised of $600 million aggregate principal amount of 5.400% senior notes due 2025 and $750 million aggregate principal amount of 5.600% senior notes due 2032. On February 1, 2023, the net proceeds were used to redeem in full, upon maturity, the $1.35 billion aggregate principal amount of our 3.250% 2013 senior notes due 2023.

Table of Contents

Our senior notes are governed by an indenture and supplemental indentures (collectively, the indenture) between us and Deutsche Bank Trust Company Americas, as trustee. The indenture contains certain covenants, including limitations on our and certain of our subsidiaries' ability to incur liens or engage in sale lease-back transactions. The indenture also contains restrictions on our ability to consolidate, merge or sell substantially all of our assets. In addition, the indenture contains other customary terms, including certain events of default, upon the occurrence of which, the senior notes may be declared immediately due and payable.

Pursuant to the indenture, we are able to redeem the senior notes of any series, in whole or in part, at any time by paying a “make whole” premium, plus accrued and unpaid interest to, but excluding, the date of redemption. Upon the occurrence of a change of control of us and a downgrade of the senior notes below an investment grade rating by each of Moody's Investors Service, Inc. and Standard & Poor's Ratings Services, we are, in certain circumstances, required to make an offer to repurchase all of the outstanding senior notes at a price equal to 101% of the aggregate principal amount of the senior notes together with accrued and unpaid interest to, but excluding, the date of repurchase.

Credit ratings

Two major corporate debt-rating organizations, Moody's and S&P, assign ratings to our short-term and long-term debt. A security rating is not a recommendation to buy, sell or hold securities and the rating is subject to revision or withdrawal at any time by the rating organization. Each rating should be evaluated independently of any other rating.

The following table provides the current ratings assigned by these rating agencies to our commercial paper and senior unsecured non-credit-enhanced long-term debt:

Pension obligations

Our employees ceased to participate in the Pfizer U.S. qualified defined benefit and U.S. retiree medical plans effective December 31, 2012, and liabilities associated with our employees under these plans were retained by Pfizer. As part of the separation from Pfizer, Pfizer continued to credit certain employees' service with Zoetis generally through December 31, 2017 (or termination of employment from Zoetis, if earlier), for certain early retirement benefits with respect to Pfizer's U.S. defined benefit pension and retiree medical plans. In connection with the employee matters agreement, Zoetis was responsible for payment of three-fifths of the total cost of the service credit continuation ($38 million) for these plans. The amount of the service cost continuation payment to be paid by Zoetis to Pfizer was determined and fixed based on an actuarial assessment of the value of the grow-in benefits and will be paid in equal installments over a period of 10 years. As of December 31, 2023, there are no remaining payments due to Pfizer.

As part of the separation from Pfizer, Pfizer transferred to us the net pension obligations associated with certain international defined benefit plans. We expect to contribute a total of $7 million to these plans in 2024.

As of December 31, 2023, the supplemental savings plan liability was $51 million.

For additional information, see Notes to Consolidated Financial Statements— Note 14. Benefit Plans.

Share repurchase program

In December 2021, our Board of Directors authorized a $3.5 billion share repurchase program. As of December 31, 2023, there was $1.5 billion remaining under this authorization. Purchases of Zoetis shares may be made at the discretion of management, depending on market conditions and business needs. Share repurchases may be executed through various means, including open market or privately negotiated transactions. During 2023, 6.3 million shares were repurchased for $1.1 billion, which excludes a $10 million accrual for excise tax on net share repurchases.

Off-balance sheet arrangements

In the ordinary course of business and in connection with the sale of assets and businesses, we may indemnify our counterparties against certain liabilities that may arise in connection with a transaction or that are related to activities prior to a transaction. These indemnifications typically pertain to environmental, tax, employee and/or product-related matters, and patent-infringement claims. If the indemnified party were to make a successful claim pursuant to the terms of the indemnification, we would be required to reimburse the loss. These indemnifications are generally subject to threshold amounts, specified claim periods and other restrictions and limitations. Historically, we have not paid significant amounts under these provisions and, as of December 31, 2023 and 2022, recorded amounts for the estimated fair value of these indemnifications are not material.

A discussion regarding our financial condition and results of operations for fiscal 2021 compared to fiscal 2020 can be found under Item 7 of Part II of our Annual Report on Form 10-K for the fiscal year ended December 31, 2021, filed with the SEC on February 15, 2022 (our “2021 Annual Report”), which is available free of charge on the SEC’s website at www.sec.gov.

Overview of our business

We are a global leader in the animal health industry, focused on the discovery, development, manufacture and commercialization of medicines, vaccines, diagnostic products and services, biodevices, genetic tests and precision animal health technology. For over 70 years, we have been innovating ways to predict, prevent, detect, and treat animal illness, and continue to stand by those raising and caring for animals worldwide - from veterinarians and pet owners to livestock farmers and ranchers.

We manage our operations through two geographic operating segments: the United States (U.S.) and International. Within each of these operating segments, we offer a diversified product portfolio for both companion animals and livestock customers in order to capitalize on local and regional trends and customer needs. See Notes to Consolidated Financial Statements—Note 19. Segment Information.

We directly market our products to veterinarians and livestock producers located in approximately 45 countries across North America, Europe, Africa, Asia, Australia and South America, and are a market leader in nearly all of the major regions in which we operate. Through our efforts to establish an early and direct presence in many emerging markets, such as Brazil, Chile, China and Mexico, we believe we are one of the largest animal health medicines and vaccines businesses as measured by revenue across emerging markets as a whole. In markets where we do not have a direct commercial presence, we generally contract with distributors that provide logistics and sales and marketing support for our products.

We believe our investments in one of the industry’s largest sales organizations, including our extensive network of technical and veterinary operations specialists, our high-quality manufacturing and reliability of supply, and our long track record of developing products that meet customer needs, has led to enduring and valued relationships with our customers. Our research and development (R&D) efforts enable us to deliver innovative products to address unmet needs and evolve our product lines so that they remain relevant for our customers.

We have approximately 300 product lines that we sell in over 100 countries for the prediction, prevention, detection and treatment of diseases and conditions that affect various companion animal and livestock species. The diversity of our product portfolio and our global operations provides stability to our overall business. For instance, in livestock, impacts on our revenue that may result from disease outbreaks or weather conditions in a particular market or region are often offset by increased sales in other regions from exports and other species as consumers shift to other animal proteins.

A summary of our 2022 performance compared with the comparable 2021 and 2020 periods follows:

Our operating environment

Industry

The animal health industry, which focuses on both companion animals and livestock, is a growing industry that impacts billions of people worldwide. The primary companion animal species are dogs, cats and horses. Factors influencing growth in demand for companion animal medicines, vaccines and diagnostics include:

•economic development and related increases in disposable income, particularly in many emerging markets;

•increasing pet ownership and pet owners’ commitment to the health and well-being of their pets;

•companion animals living longer;

•increasing medical treatment of companion animals; and

•advances in companion animal medicines, vaccines and diagnostics.

The primary livestock species for the production of animal protein are cattle (both beef and dairy), swine, poultry, fish and sheep. Livestock health

and production are essential to meeting the growing demand for animal protein of a global population. Factors influencing growth in demand for livestock medicines and vaccines include:

•human population growth and increasing standards of living, particularly in many emerging markets;

•increasing demand for improved nutrition, particularly animal protein;

•natural resource constraints, such as scarcity of arable land, fresh water and increased competition for cultivated land, resulting in fewer resources that will be available to meet an increasing demand for animal protein;

•increasing urbanization; and

•increased focus on food safety and food security.

Manufacturing and supply

In order to sell our products, we must be able to produce and ship our products in sufficient quantities. Many of our products involve complex manufacturing processes and are sole-sourced from certain manufacturing sites. Minor deviations in our manufacturing or logistical processes, such as temperature excursions or improper package sealing, could result in delays, inventory shortages, unanticipated costs, product recalls, product liability and/or regulatory action. In addition, a number of factors could cause production interruptions that could result in launch delays, inventory shortages, recalls, unanticipated costs or issues with our supply agreements with third parties.

In 2022, we experienced supply chain challenges for certain products including Simparica Trio, and the component parts of certain products including Librela and Solensia, and some of our other products, resulting from strong demand as well as competition for manufacturing inputs with human health vaccine development during the pandemic. Our global manufacturing network team remains committed to addressing specific issues with ongoing supply chain optimizations, controlled launches for new products in additional markets and customer coordination. However, some of these challenges are expected to continue in 2023.

Our manufacturing network may be unable to meet the demand for our products or we may have excess capacity if demand for our products changes. The unpredictability of a product's regulatory or commercial success or failure, the lead time necessary to construct highly technical and complex manufacturing sites, and shifting customer demand increase the potential for capacity imbalances.

The overall economic environment

In addition to industry-specific factors, we, like other businesses, face challenges related to global economic conditions, the current economic downturn and high inflation. Growth in both the livestock and companion animal sectors is driven by overall economic development and related growth, particularly in many emerging markets. In the past, certain of our customers and suppliers have been affected directly by economic downturns or inflation, which decreased the demand for our products and, in some cases, hindered our ability to collect amounts due from customers.

The cost of medicines and vaccines to our livestock producer customers is small relative to other production costs, including feed, and the use of these products is intended to improve livestock producers’ economic outcomes. As a result, demand for our products has historically been more stable than demand for other production inputs. Similarly, industry sources have reported that pet owners indicated a preference for reducing spending on other aspects of their lifestyle, including entertainment, clothing and household goods, before reducing spending on pet care. Each of these factors, plus our broad and innovative portfolio, contributes to our ability to incorporate inflationary challenges into our product pricing and mitigate the impact on our results. While these factors have mitigated the impact of prior downturns in the global economy, economic challenges, including the current economic downturn and inflation, could increase cost sensitivity among our customers, which may result in reduced demand for our products, which could have a material adverse effect on our operating results and financial condition.

Product development initiatives

Our future success depends on both our existing product portfolio and our pipeline of new products, including new products that we may develop through joint ventures and products that we are able to obtain through license or acquisition. We believe we are an industry leader in animal health R&D, with a track record of generating new products and product lifecycle innovation. The majority of our R&D programs focus on product lifecycle innovation, which is defined as R&D programs that leverage existing animal health products by adding new species or claims, achieving approvals in new markets or creating new combinations and reformulations. In addition to traditional medicines and vaccines, we develop products across additional categories to address the needs of veterinarians and producers to predict, prevent, detect and treat conditions in both companion animals and livestock, including products and services in diagnostics, genetics, precision animal health and digital and data analytics.

Perceptions of product quality, safety and reliability

We believe that animal health customers value high-quality manufacturing and reliability of supply. The importance of quality and safety concerns to pet owners, veterinarians and livestock producers also contributes to animal health brand loyalty, which often continues after the loss of patent-based and regulatory exclusivity. We depend on positive perceptions of the safety and quality of our products by our customers, veterinarians and end-users.

In addition, negative beliefs about animal health products generally could impact demand for our products. For example, the issue of the potential transfer of increased antibacterial resistance in bacteria from food-producing animals to human pathogens, and the causality of that transfer, continue to be the subject of global scientific and regulatory discussion. Antibacterials refer to small molecules that can be used to treat or prevent bacterial infections and are a sub-categorization of the products that make up our anti-infectives and medicated feed additives portfolios. In some countries, this issue has led to government restrictions and bans on the use of specific antibacterials in some food-producing animals, regardless of the route of administration (in feed or injectable). These restrictions are more prevalent in countries where animal protein is plentiful and governments are willing to take action even when there is scientific uncertainty. In addition, consumer preferences in some markets have impacted the use of antibacterials in food producing animals. Such restrictions and consumer preferences in some cases may negatively impact sales of our antibacterial products, but in other instances may increase sales of our products that can be used as antibacterial alternatives. Our total revenue attributable to antibacterials for livestock was approximately $1 billion for the year ended December 31, 2022.

Similarly, concerns regarding greenhouse gas emissions and other potential environmental impacts of livestock production have led to some consumers opting to limit or avoid consuming animal products. However, we believe the impact of this trend is limited as the livestock industry is still expected to continue to grow in order to feed a growing global population.

Changing distribution channels for companion animal products

In most markets, companion animal owners typically purchase their animal health products directly from veterinarians. However, in the U.S. and certain other markets, companion animal owners increasingly have the option to purchase animal health products from sources other than veterinarians, such as Internet-based retailers, “big-box” retail stores or other over-the-counter distribution channels. This trend has been demonstrated by the shift away from the veterinarian distribution channel in the sale of flea and tick products in recent years and has been accelerated by the increase in e-commerce during the COVID-19 pandemic. We believe the ability of pet owners to purchase our products online and from retail stores may increase pet owner compliance and result in increased sales, particularly in the near term. However, over time, we may be unable to sustain our current margins due to the increased purchasing power of such retailers as compared to traditional veterinary practices.

In addition, this trend could negatively impact the sales of products we primarily sell through the veterinarian distribution channel, as any decrease in visits to veterinarians by companion animal owners could reduce our market share and sales of such products. A reduction in the number of pet owners who purchase our products directly from their veterinarian could also lead to increased use of generic alternatives to our products or the increased substitution of our products with other animal health products or human health products if such other products are deemed to be lower-cost alternatives.

Competition

The animal health industry is highly competitive. Although our business is the largest based on revenue in the animal health industry (which includes medicines, vaccines and diagnostics), we face competition in the regions in which we operate. Principal methods of competition vary depending on the particular region, species, product category or individual product. Some of these methods include new product development, quality, price, service and promotion to veterinary professionals, pet owners and livestock producers. Our competitors include standalone animal health businesses and the animal health businesses of large pharmaceutical companies. In recent years, there has been an increase in consolidation in the animal health industry. There are also many start-up companies working in the animal health area. In addition to competition from established market participants, there could be new entrants to the animal health medicines, vaccines and diagnostics industry in the future. We also compete with companies that produce generic products, following our products’ loss of exclusivity in a given market. For example, Draxxin currently competes with generic products in key markets including the U.S., Europe, Canada, Mexico and Australia. Since 2021, the first year of generic competition, sales of Draxxin declined by 45% in the U.S., its largest market, and additional declines are expected in subsequent years. For more information regarding the generic competition we expect to encounter as patents on certain of our key products expire, see Item 1. Business – Intellectual Property.

Russia’s Invasion of Ukraine

Russia’s invasion of Ukraine and the global response, including sanctions imposed by the United States and other countries, have increased global economic and political uncertainty. As we announced on March 16, 2022, our first concern remains the safety of our colleagues and their families in Ukraine. Our operations in Russia are focused on maintaining a supply of medicines and vaccines in compliance with any sanctions that are put in place. We do not directly source input materials or components from Russia and do not have any manufacturing plants in Russia or Ukraine. This crisis did not have a material adverse effect on our results or financial condition during 2022 and we do not expect it to have a material adverse effect on our results or financial condition going forward.

COVID-19 Update

We continue to closely monitor the impact of the COVID-19 pandemic and the resulting global economic downturn on all aspects of our business across geographies, including how it has and may continue to impact our customers, workforce, suppliers and vendors. We cannot predict the impact that the COVID-19 pandemic will have on our customers, vendors and suppliers; however, any material effect on these parties could adversely impact us. The situation surrounding COVID-19 remains fluid, and we will continue to actively monitor the situation and may take actions that alter our business operations that we determine are in the best interests of our workforce, customers, vendors, suppliers, and other stakeholders, or as required by federal, state, or local authorities. For further information regarding the impact of COVID-19 on the Company, see Item 1A, Risk Factors in this Annual Report on Form 10-K.

Disease Outbreaks

Sales of our livestock products have in the past, and may in the future be, adversely affected by the outbreak of disease carried by animals. Outbreaks of disease may reduce regional or global sales of particular animal-derived food products or result in reduced exports of such products, either due to heightened export restrictions or import prohibitions, which may reduce demand for our products. Also, the outbreak of any highly contagious disease near our main production sites could require us to immediately halt production of our products at such sites or force us to incur substantial expenses in procuring raw materials or products elsewhere. Alternatively, sales of products that treat specific disease outbreaks may increase.

Weather conditions, climate change and the availability of natural resources

The animal health industry and demand for many of our animal health products in a particular region are affected by weather conditions, as usage of our products follows varying weather patterns and weather-related pressures from pests, such as ticks. As a result, we may experience regional and seasonal fluctuations in our results of operations.

In addition, veterinary hospitals and practitioners depend on visits from and access to the animals under their care. Veterinarians’ patient volume and ability to operate could be adversely affected if they experience prolonged snow, ice or other severe weather conditions, particularly in regions not accustomed to sustained inclement weather. Furthermore, weather conditions, including excessive cold or heat, natural disasters and other events, could negatively impact our livestock customers by impairing the health or growth of their animals or the production or availability of feed, as well as disrupting their normal operations. For example, livestock producers depend on the availability of natural resources, including large supplies of fresh water. Their animals’ health and their ability to operate could be adversely affected if they experience a shortage of fresh water due to human

33 |

Table of Contents

population growth, climate change or floods, droughts or other weather conditions. In the event of adverse weather conditions, climate-change related impacts or a shortage of fresh water, veterinarians and livestock producers may purchase less of our products.

For example, drought conditions could negatively impact, among other things, the supply of corn and the availability of grazing pastures. A decrease in harvested corn results in higher corn prices, which could negatively impact the profitability of livestock producers of cattle, pork and poultry. Higher corn prices and reduced availability of grazing pastures contribute to reductions in herd or flock sizes that in turn result in less spending on animal health products. As such, a prolonged drought could have a material adverse impact on our operating results and financial condition.

Adverse weather conditions, natural disasters and climate change may also impact the aquaculture business. Changes in water temperatures could affect the timing of reproduction and growth of various fish species, as well as trigger the outbreak of certain waterborne diseases.

Foreign exchange rates

Significant portions of our revenue and costs are exposed to changes in foreign exchange rates. Our products are sold in more than 100 countries and, as a result, our revenue is influenced by changes in foreign exchange rates. For the year ended December 31, 2022, approximately 42% of our revenue was denominated in foreign currencies. We seek to manage our foreign exchange risk, in part, through operational means, including managing same-currency revenue in relation to same-currency costs and same-currency assets in relation to same-currency liabilities. As we operate in multiple foreign currencies, including the Australian dollar, Brazilian real, British pound, Canadian dollar, Chinese yuan, euro and other currencies, changes in those currencies relative to the U.S. dollar will impact our revenue, cost of goods and expenses, and consequently, net income. Exchange rate fluctuations may also have an impact beyond our reported financial results and directly impact operations. These fluctuations may affect the ability to buy and sell our goods and services between markets impacted by significant exchange rate variances. For the year ended December 31, 2022, approximately 58% of our total revenue was in U.S. dollars. Our year-over-year total revenue growth was unfavorably impacted by 4% from changes in foreign currency values relative to the U.S. dollar.

Our growth strategies

We seek to enhance the health of animals and to bring solutions to our customers who raise and care for them. We have a global presence in both developed and emerging markets and across eight core species. We intend to grow our business by pursuing the following core strategies:

•drive innovative growth - We seek to deliver new products and solutions as well as lifecycle innovations across the continuum of care that spans from disease prediction and prevention to detection and treatment. We are focused on innovating across vaccines, pharmaceuticals, diagnostics, genetics, biodevices, and other product segments, and across all core species. Where appropriate, we complement internal R&D programs with external innovations;

•enhance customer experience - We believe that delighting our customers with compelling and personalized experiences that enable them to provide the best care for animals is critical for our success. We are focused on providing greater value to our customers through the integration and connectedness of our portfolio and by reducing frictions in the way they engage with us and our products and solutions;

•lead in digital and data analytics - We believe that healthcare insights enabled by data and digital technology and complemented with our comprehensive portfolio of products and solutions will be critical in enhancing care for animals and improving livestock productivity;

•cultivate a high-performing organization - We view the strength of our leadership team and our talented colleagues around the world as a critical component of our past and future success. We are committed to continuing to be a company our colleagues can be proud of and to attracting, retaining and developing the best, most diverse talent in the industry. We are further committed to sustaining a diverse, equitable and inclusive work environment for our colleagues; and

•champion a healthier, more sustainable future - As the world’s leading animal health company, our business purpose is well aligned with our social purpose. We strive to make a meaningful difference in society through the three pillars of our sustainability approach: (1) by caring and collaborating with our customers, colleagues, and communities, and the animals that depend on them by improving access to care for animals, by creating a diverse, equitable, and inclusive work environment, and by supporting the veterinary profession; (2) by leveraging our innovation capabilities to develop solutions that improve productivity, keep animals healthy, and fight emerging infectious diseases; and (3) by taking actions to protect our planet that reduce our footprint on the environment.

Components of revenue and costs and expenses

Our revenue, costs and expenses are reported for the year ended December 31 for each year presented, except for operations outside the U.S., for which the financial information is included in our consolidated financial statements for the fiscal year ended November 30 for each year presented.

Revenue

Our revenue is primarily derived from our diversified product portfolio of medicines, vaccines and diagnostic products and services used to treat and protect companion animals and livestock. Generally, our products are promoted to veterinarians and livestock producers by our sales organization which includes sales representatives and technical and veterinary operations specialists, and then sold directly by us or through distributors, retailers or e-commerce outlets. The depth of our product portfolio enables us to address the varying needs of customers in different species and geographies. In 2022, our two top-selling products and product lines, Simparica/Simparica Trio and Apoquel, each contributed approximately 12% and 10% of our revenue, respectively, and combined with our next three top-selling products and product lines, Cytopoint, Revolution/Revolution Plus/Stronghold and ceftiofur line, these five products and product lines contributed approximately 37% of our revenue. Our ten top-selling products and product lines contributed 49% of our revenue. For additional information regarding our products, including descriptions of our product lines that each represented approximately 1% or more of our revenue in 2022, see Item 1. Business—Products.

Costs and expenses

Costs of sales consist primarily of cost of materials, facilities and other infrastructure used to manufacture our medicine and vaccine products, as well as costs to operate our reference labs and royalty expenses associated with the intellectual property of our products, when relevant.

34 |

Table of Contents

Selling, general and administrative (SG&A) expenses consist of, among other things, the internal and external costs of marketing, promotion, advertising and shipping and handling as well as certain costs related to business technology, facilities, legal, finance, human resources, business development, public affairs and procurement.

Research and development (R&D) expenses consist primarily of project costs specific to new product R&D and product lifecycle innovation, overhead costs associated with R&D operations and investments that support local market clinical trials for approved indications and expenses related to regulatory approvals for our products. We do not disaggregate R&D expenses by research stage or by therapeutic area for purposes of managing our business.

Amortization of intangible assets consists primarily of the amortization expense for identifiable finite-lived intangible assets that have been acquired through business combinations. These assets consist of, but are not limited to, developed technology, brands and trademarks.

Restructuring charges and certain acquisition-related costs consist of all restructuring charges (those associated with acquisition activity and those associated with cost reduction/productivity initiatives), as well as costs associated with acquiring and integrating businesses. Restructuring charges are associated with employees, assets and activities that will not continue in the company. Acquisition-related costs are associated with acquiring and integrating acquired businesses, such as Abaxis in 2018, and may include transaction costs and expenditures for consulting and the integration of systems and processes.

Other (income)/deductions—net consists of various items, primarily net (gains)/losses on asset disposals, interest income, royalty-related income, foreign exchange translation (gains)/losses and certain asset impairment charges.

Significant accounting policies and application of critical accounting estimates

In presenting our financial statements in conformity with U.S. GAAP, we are required to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenue, costs and expenses and related disclosures. For a description of our significant accounting policies, see Notes to Consolidated Financial Statements—Note 3. Significant Accounting Policies.

We believe that the following accounting policies are critical to an understanding of our consolidated financial statements as they require the application of the most difficult, subjective and complex judgments and, therefore, could have the greatest impact on our financial statements: (i) fair value; (ii) revenue; (iii) asset impairment reviews; and (iv) contingencies.

Below are some of our more critical accounting estimates. See also Notes to Consolidated Financial Statements—Note 3. Significant Accounting Policies: Estimates and Assumptions for a discussion about the risks associated with estimates and assumptions.

Fair value

For a discussion about the application of fair value to our long-term debt and financial instruments, see Notes to Consolidated Financial Statements—Note 9. Financial Instruments.

For a discussion about the application of fair value to our business combinations, see Notes to Consolidated Financial Statements—Note 3. Significant Accounting Policies: Fair Value.

For a discussion about the application of fair value to our asset impairment reviews, see Asset impairment reviews below.

Revenue

Our gross product revenue is subject to deductions that are generally estimated and recorded in the same period that the revenue is recognized and primarily represents sales returns and revenue incentives. For example:

•for sales returns, we perform calculations in each market that incorporate the following, as appropriate: local returns policies and practices; returns as a percentage of revenue; an understanding of the reasons for past returns; estimated shelf life by product; an estimate of the amount of time between shipment and return or lag time; and any other factors that could impact the estimate of future returns, product recalls, discontinuation of products or a changing competitive environment; and

•for revenue incentives, we use our historical experience with similar incentives programs to estimate the impact of such programs on revenue.

If any of our ratios, factors, assessments, experiences or judgments are not indicative or accurate predictors of our future experience, our results could be materially affected. Although the amounts recorded for these revenue deductions are dependent on estimates and assumptions, historically our adjustments to actual results have not been material. The sensitivity of our estimates can vary by program, type of customer and geographic location.

Amounts recorded for revenue deductions can result from a complex series of judgments about future events and uncertainties and can rely on estimates and assumptions. For further information about the risks associated with estimates and assumptions, see Notes to Consolidated Financial Statements—Note 3. Significant Accounting Policies: Estimates and Assumptions.

Asset impairment reviews

We review all of our long-lived assets for impairment indicators throughout the year and we perform detailed testing whenever impairment indicators are present. In addition, we perform impairment testing for goodwill and indefinite-lived intangible assets at least annually. When necessary, we record charges for impairments of long-lived assets for the amount by which the fair value is less than the carrying value of these assets.

Our impairment review processes are described below and in Notes to Consolidated Financial Statements—Note 3. Significant Accounting Policies: Amortization of Intangible Assets, Depreciation and Certain Long-Lived Assets and, for deferred tax assets, in Note 3. Significant Accounting Policies: Deferred Tax Assets and Liabilities and Income Tax Contingencies.

Table of Contents

Examples of events or circumstances that may be indicative of impairment include:

•a significant adverse change in the extent or manner in which an asset is used. For example, restrictions imposed by the regulatory authorities could affect our ability to manufacture or sell a product; and

•a projection or forecast that demonstrates losses or reduced profits associated with an asset. This could result, for example, from the introduction of a competitor’s product that results in a significant loss of market share or the inability to achieve the previously projected revenue growth, or from the lack of acceptance of a product by customers.

For finite-lived identifiable intangible assets, such as developed technology rights, and for other long-lived assets, such as property, plant and equipment, whenever impairment indicators are present, we calculate the undiscounted value of the projected cash flows associated with the asset, or asset group, and compare this estimated amount to the carrying amount. If the carrying amount is found to be greater, we record an impairment loss for the excess of book value over fair value. In addition, in all cases of an impairment review, we re-evaluate the remaining useful lives of the assets and modify them, as appropriate.

Our impairment reviews of most of our long-lived assets depend on the determination of fair value, as defined by U.S. GAAP, and these judgments can materially impact our results of operations. A single estimate of fair value can result from a complex series of judgments about future events and uncertainties and can rely on estimates and assumptions.

Intangible assets other than goodwill

We test indefinite-lived intangible assets for impairment at least annually, or more frequently if impairment indicators exist, by first assessing qualitative factors to determine whether it is more likely than not that the fair value of the indefinite-lived intangible asset is less than its carrying amount. If we conclude it is more likely than not that the fair value is less than the carrying amount, a quantitative test that compares the fair value of the indefinite-lived intangible asset with its carrying value is performed. If the fair value is less than the carrying amount, an impairment loss is recognized. Impairments of identifiable intangible assets other than goodwill, are recorded in Restructuring charges and certain acquisition-related costs and Other (income)/deductions—net, as applicable. We did not have any material intangible asset impairment charges for the years ended December 31, 2022, 2021 and 2020.

When we are required to determine the fair value of intangible assets other than goodwill, we use an income approach, specifically the multi-period excess earnings method, also known as the discounted cash flow method. We start with a forecast of all the expected net cash flows associated with the asset, which includes the application of a terminal value for indefinite-lived assets, and then we apply an asset-specific discount rate to arrive at a net present value amount. Some of the more significant estimates and assumptions inherent in this approach include: the amount and timing of the projected net cash flows, which includes the expected impact of competitive, legal and/or regulatory forces on the projections, the impact of technological risk associated with IPR&D assets, as well as the selection of a long-term growth rate; the discount rate, which seeks to reflect the risks inherent in the projected cash flows; foreign currency fluctuations; and the effective tax rate, which seeks to incorporate the geographic diversity of the projected cash flows.

While all identifiable intangible assets can be impacted by events and thus lead to impairment, in general, identifiable intangible assets that are at the highest risk of impairment include IPR&D assets ($77 million as of December 31, 2022). IPR&D assets are higher-risk assets because R&D is an inherently risky activity.

For a description of our accounting policy, see Notes to Consolidated Financial Statements—Note 3. Significant Accounting Policies: Amortization of Intangible Assets, Depreciation and Certain Long-Lived Assets.

Goodwill

Goodwill represents the excess of the consideration transferred over the fair value of net assets of businesses purchased and is assigned to reporting units. We test goodwill for impairment on at least an annual basis, or more frequently if necessary, either by assessing qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount or by performing a periodic quantitative assessment.

Factors considered in the qualitative assessment include general macroeconomic conditions, conditions specific to the industry and market, cost factors which could have a significant effect on earnings or cash flows, the overall financial performance of the reporting unit and whether there have been sustained declines in our share price. Additionally, we evaluate the extent to which the fair value exceeded the carrying value of the reporting unit at the date of the last quantitative assessment performed.

When performing a quantitative assessment to test for goodwill impairment we utilize the income approach, which is forward-looking, and relies primarily on internal forecasts. Within the income approach, the method that we use is the discounted cash flow method. We start with a forecast of all the expected net cash flows associated with the reporting unit, which includes the application of a terminal value, and then apply a reporting unit-specific discount rate to arrive at a net present value. Some of the more significant estimates and assumptions inherent in this approach include: the amount and timing of the projected net cash flows, which includes the expected impact of technological risk and competitive, legal and/or regulatory forces on the projections, as well as the selection of a long-term growth rate; the discount rate, which seeks to reflect the various risks inherent in the projected cash flows; and the effective tax rate, which seeks to incorporate the geographic diversity of the projected cash flows.

We test goodwill for impairment on at least an annual basis, or more frequently if necessary, either by assessing qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount or by performing a periodic quantitative assessment. In 2022 and 2021, we performed a periodic quantitative impairment assessment as of September 30, 2022 and 2021, respectively, which did not result in the impairment of goodwill associated with any of our reporting units.

For all of our reporting units, there are a number of future events and factors that may impact future results and that could potentially have an impact on the outcome of subsequent goodwill impairment testing. For a list of these factors, see Forward-looking statements and factors that may affect future results.

For a discussion about legal contingencies, guarantees and indemnifications, see Notes to Consolidated Financial Statement—Note 18. Commitments and Contingencies.

Non-GAAP financial measures

We report information in accordance with U.S. generally accepted accounting principles (GAAP). Management also measures performance using non-GAAP financial measures that may exclude certain amounts from the most directly comparable GAAP measure. Despite the importance of these measures to management in goal setting and performance measurement, non-GAAP financial measures have no standardized meaning prescribed by U.S. GAAP and, therefore, have limits in their usefulness to investors and may not be comparable to the calculation of similar measures of other companies. We present certain identified non-GAAP measures solely to provide investors with useful information to more fully understand how management assesses performance.

Operational Growth

We believe that it is important to not only understand overall revenue and earnings growth, but also “operational growth.” Operational growth is a non-GAAP financial measure defined as revenue or earnings growth excluding the impact of foreign exchange. This measure provides information on the change in revenue and earnings as if foreign currency exchange rates had not changed between the current and prior periods to facilitate a period-to-period comparison. We believe this non-GAAP measure provides a useful comparison to previous periods for the company and investors, but should not be viewed as a substitute for U.S. GAAP reported growth.

Adjusted Net Income and Adjusted Earnings Per Share

Adjusted net income and the corresponding adjusted earnings per share (EPS) are non-GAAP financial measures of performance used by management. We believe these financial measures are useful supplemental information to investors when considered together with our U.S. GAAP financial measures. We report adjusted net income to portray the results of our major operations, and the discovery, development, manufacture and commercialization of our products, prior to considering certain income statement elements. We define adjusted net income and adjusted EPS as net income attributable to Zoetis and EPS before the impact of purchase accounting adjustments, acquisition-related costs and certain significant items.

We recognize that, as an internal measure of performance, the adjusted net income and adjusted EPS measures have limitations, and we do not restrict our performance management process solely to these metrics. A limitation of the adjusted net income and adjusted EPS measures is that they provide a view of our operations without including all events during a period, such as the effects of an acquisition or amortization of purchased intangibles, and do not provide a comparable view of our performance to other companies. The adjusted net income and adjusted EPS measures are not, and should not be viewed as, a substitute for U.S. GAAP reported net income attributable to Zoetis and reported EPS. See the Adjusted Net Income section below for more information.

Restructuring charges and certain acquisition-related costs were $11 million and $43 million in 2022 and 2021, respectively. Restructuring charges and certain acquisition-related costs in 2022 primarily consisted of integration and acquisition costs related to recent acquisitions, employee termination and exit costs associated with cost-reduction and productivity initiatives in certain international markets and asset impairment charges related to the consolidation of manufacturing sites in China. Restructuring charges and certain acquisition-related costs in 2021 primarily consisted of employee termination costs associated with the realignment of our international operations and other costs associated with cost-reduction and productivity initiatives, asset impairment charges related to the consolidation of manufacturing sites in China and integration costs related to recent acquisitions.

Provision for taxes on income$545$454$3602026
Effective tax rate20.5%18.2%18.0%

The income tax provision in the Consolidated Statements of Income includes tax costs and benefits, such as uncertain tax positions, repatriation decisions and audit settlements, among others.

2022 vs. 2021

Our effective tax rate was 20.5% for 2022, compared with 18.2% for 2021. The higher effective tax rate for 2022 was attributable to a less favorable jurisdictional mix of earnings (which includes the impact of the location of earnings and repatriation costs), a lower benefit in the U.S. related to foreign-derived intangible income and lower net discrete tax benefits in 2022. Jurisdictional mix of earnings can vary depending on repatriation decisions, operating fluctuations in the normal course of business and the impact of non-deductible and non-taxable items.

On August 16, 2022, the U.S. Inflation Reduction Act of 2022 (the “IRA”) was enacted which, among other changes, implements a 15% alternative minimum tax on financial statement income of certain large corporations, a 1% excise tax on net stock repurchases and several tax incentives to promote clean energy. The alternative minimum tax and excise tax are effective for taxable years beginning after December 31, 2022 and the incentives to promote clean energy have various different effective dates. We do not currently expect the IRA to have a material impact on our financial results, including our annual estimated effective tax rate.

Operating Segment Results

Beginning in the first quarter of 2021, certain costs associated with information technology that specifically support our global manufacturing operations, which were previously reported in Other unallocated, are now reported in Corporate. In addition, in the first quarter of 2021, the company realigned certain management responsibilities. These changes did not impact the determination of our operating segments, however they resulted in the reallocation of certain costs between segments. These changes primarily include the following: (i) certain diagnostics costs, which were previously reported in Corporate, are now reported in our U.S. results; and (ii) certain other miscellaneous costs, which were previously reported in our U.S. results, are now reported in Corporate.

2022 vs. 2021

U.S. operating segment

U.S. segment revenue increased by $271 million, or 7%, in 2022 compared with 2021, of which $351 million resulted from growth in companion animal products, offset by a $80 million decline in livestock products.

•Companion animal revenue growth was driven primarily by increased sales of parasiticides, primarily Simparica Trio. In-line product growth benefited from increased sales of our key dermatology portfolio and vaccines, partially offset by declines in small animal diagnostics.

•Livestock revenue declined due to cattle and poultry, partially offset by growth in swine. Sales of cattle products declined as a result of generic competition, supply constraints and unfavorable market conditions, including increased input costs and dry weather conditions. Sales of products in our poultry portfolio declined due to generic competition for Zoamix, the company's alternative to antibiotics in medicated feed additives. Sales of swine products grew as a result of favorable market conditions for producers and increased disease prevalence.

U.S. segment earnings increased by $194 million, or 8%, in 2022 compared with 2021, primarily due to revenue and gross margin growth, partially offset by higher operating expenses.

International operating segment

International segment revenue increased by $29 million, or 1%, in 2022 compared with 2021. Operational revenue growth was $332 million, or 9%, reflecting growth of $323 million in companion animal products and $9 million in livestock products.

•Companion animal operational revenue growth resulted primarily from increased sales of our key dermatology portfolio, the recent launches of our mAb products, Librela and Solensia, and growth in the Simparica franchise. Growth across the broader in-line portfolio benefited from increased pet ownership and standards of care.

41 |

Table of Contents

•Livestock operational revenue growth was due to increased sales of fish, sheep, poultry and cattle products, partially offset by decreased sales of swine products. Growth in our fish portfolio was primarily the result of increased sales of vaccines across key salmon markets, including Norway and Chile. Sales of sheep products grew as a result of favorable market conditions and new product launches in Australia. Sales of poultry products grew due to price, market growth and demand generation efforts in key poultry markets. Sales of cattle products grew due to favorable market conditions and price in key and emerging markets, including Australia, Turkey, Argentina and China, partially offset by supply constraints and unfavorable market conditions in Brazil. Sales of swine products decreased due to lower pork prices and COVID-related lockdowns in China, which temporarily impacted our supply chain in the market, as well as a difficult comparative period versus the prior year. Swine was also impacted by supply constraints across other international markets, as well as lower sales across Europe due to reduced exports to China and higher input costs for producers.

•Additionally, International segment revenue was unfavorably impacted by foreign exchange which decreased revenue by approximately $303 million, or 8%, primarily driven by the euro, Turkish lira, Japanese yen, British pound and Australian dollar.

International segment earnings increased by $42 million, or 2%, in 2022 compared with 2021. Operational earnings growth was $239 million, or 12%, primarily due to revenue and gross margin growth, partially offset by higher operating expenses.

Other business activities

Other business activities includes our Client Supply Services contract manufacturing results, our human health business and expenses associated with our dedicated veterinary medicine research and development organization, research alliances, U.S. regulatory affairs and other operations focused on the development of our products. Other R&D-related costs associated with non-U.S. market and regulatory activities are generally included in the International segment.

2022 vs. 2021

Other business activities net loss increased by $18 million, or 4%, in 2022 compared with 2021, reflecting an increase in R&D costs due to an increase in compensation-related costs to support innovation, increase in facility costs and an increase in project investments, partially offset by favorable foreign exchange and higher earnings in our human health business.

Reconciling items

Reconciling items include certain costs that are not allocated to our operating segments results, such as costs associated with the following:

•Corporate, which includes certain costs associated with information technology, facilities, legal, finance, human resources, business development and communications, among others. These costs also include certain compensation costs, certain procurement costs, and other miscellaneous operating expenses that are not charged to our operating segments, as well as interest income and expense;

•Certain transactions and events such as (i) Purchase accounting adjustments, which includes expenses associated with the amortization of fair value adjustments to inventory, intangible assets and property, plant and equipment; (ii) Acquisition-related activities, which includes costs for acquisitions and integration; and (iii) Certain significant items, which includes non-acquisition-related restructuring charges, certain asset impairment charges, certain legal and commercial settlements, and costs associated with cost reduction/productivity initiatives; and

•Other unallocated, which includes (i) certain overhead expenses associated with our global manufacturing operations not charged to our operating segments; (ii) certain costs associated with finance that specifically support our global manufacturing operations; (iii) certain supply chain and global logistics costs; and (iv) certain procurement costs.

2022 vs. 2021

Corporate expenses increased by $21 million, or 2%, in 2022 compared with 2021, primarily due to unfavorable foreign exchange and investments in information technology, partially offset by lower compensation-related costs and interest expense, as well as higher interest income and charitable contributions in the prior year.

Other unallocated expenses increased by $68 million, or 22%, in 2022 compared with 2021, primarily due to higher manufacturing costs and freight charges, partially offset by favorable foreign exchange.

Adjusted net income

General description of adjusted net income (a non-GAAP financial measure)

Adjusted net income is an alternative view of performance used by management, and we believe that investors’ understanding of our performance is enhanced by disclosing this performance measure. The adjusted net income measure is an important internal measurement for us. Additionally, we measure our overall performance on this basis in conjunction with other performance metrics. The following are examples of how the adjusted net income measure is utilized:

•senior management receives a monthly analysis of our operating results that is prepared on an adjusted net income basis;

•our annual budgets are prepared on an adjusted net income basis; and

•other goal setting and performance measurements.

Purchase accounting adjustments

Adjusted net income is calculated prior to considering certain significant purchase accounting impacts that result from business combinations and net asset acquisitions. These impacts, primarily associated with certain acquisitions, include amortization related to the increase in fair value of the acquired finite-lived intangible assets and depreciation related to the increase/decrease to fair value of the acquired fixed assets. Therefore, the adjusted net income measure includes the revenue earned upon the sale of the acquired products without considering the aforementioned significant charges.

42 |

Table of Contents

While certain purchase accounting adjustments can occur through 20 or more years, this presentation provides an alternative view of our performance that is used by management to internally assess business performance. We believe the elimination of amortization attributable to acquired intangible assets provides management and investors an alternative view of our business results by providing a degree of parity to internally developed intangible assets for which R&D costs previously have been expensed.

A completely accurate comparison of internally developed intangible assets and acquired intangible assets cannot be achieved through adjusted net income. These components of adjusted net income are derived solely from the impact of the items listed above. We have not factored in the impact of any other differences in experience that might have occurred if we had discovered and developed those intangible assets on our own, and this approach does not intend to be representative of the results that would have occurred in those circumstances. For example, our R&D costs in total, and in the periods presented, may have been different; our speed to commercialization and resulting revenue, if any, may have been different; or our costs to manufacture may have been different. In addition, our marketing efforts may have been received differently by our customers. As such, in total, there can be no assurance that our adjusted net income amounts would have been the same as presented had we discovered and developed the acquired intangible assets.

Acquisition-related costs

Adjusted net income is calculated prior to considering transaction and integration costs associated with significant business combinations or net asset acquisitions because these costs are unique to each transaction and represent costs that were incurred to acquire and integrate certain businesses as a result of the acquisition decision. We have made no adjustments for the resulting synergies.

We believe that viewing income prior to considering these charges provides investors with a useful additional perspective because the significant costs incurred in a business combination result primarily from the need to eliminate duplicate assets, activities or employees––a natural result of acquiring a fully integrated set of activities. For this reason, we believe that the costs incurred to convert disparate systems, to close duplicative facilities or to eliminate duplicate positions (for example, in the context of a business combination) can be viewed differently from those costs incurred in the ordinary course of business.

The integration costs associated with a business combination may occur over several years, with the more significant impacts generally ending within three years of the transaction. Because of the need for certain external approvals for some actions, the span of time needed to achieve certain restructuring and integration activities can be lengthy. For example, due to the regulated nature of the animal health medicines, vaccines and diagnostic business, the closure of excess facilities can take several years, as all manufacturing changes are subject to extensive validation and testing and must be approved by the FDA and/or other regulatory authorities.

Certain significant items

Adjusted net income is calculated excluding certain significant items. Certain significant items represent substantive, unusual items that are evaluated on an individual basis. Such evaluation considers both the quantitative and the qualitative aspect of their unusual nature. Unusual, in this context, may represent items that are not part of our ongoing business; items that, either as a result of their nature or size, we would not expect to occur as part of our normal business on a regular basis; items that would be nonrecurring; or items that relate to products that we no longer sell. While not all-inclusive, examples of items that could be included as certain significant items would be costs related to a major non-acquisition-related restructuring charge and associated implementation costs for a program that is specific in nature with a defined term, such as those related to our non-acquisition-related cost-reduction and productivity initiatives; amounts related to disposals of products or facilities that do not qualify as discontinued operations as defined by U.S. GAAP; certain asset impairments; adjustments related to the resolution of certain tax positions; significant currency devaluation; the impact of adopting certain significant, event-driven tax legislation; costs related to our CEO transition in fiscal 2020; or charges related to legal matters. See Notes to Consolidated Financial Statements— Note 18. Commitments and Contingencies. Our normal, ongoing defense costs or settlements of and accruals on legal matters made in the normal course of our business would not be considered certain significant items.

(a)    The effective tax rate on adjusted pretax income is 20.3%, 18.6% and 18.3% in 2022, 2021 and 2020, respectively.

The higher effective tax rate for 2022, compared with 2021, was attributable to a less favorable jurisdictional mix of earnings (which includes the impact of the location of earnings and repatriation costs), a lower benefit in the U.S. related to foreign-derived intangible income and lower net discrete tax benefits in 2022. Jurisdictional mix of earnings can vary depending on repatriation decisions, operating fluctuations in the normal course of business and the impact of non-deductible and non-taxable items.

The higher effective tax rate for 2021, compared with 2020, was primarily attributable to changes in the jurisdictional mix of earnings, which includes the impact of the location of earnings, repatriation costs, operating fluctuations in the normal course of business and the impact of non-deductible and non-taxable items, as well as higher net discrete tax benefits in 2020, partially offset by a benefit in the U.S. related to foreign-derived intangible income in 2021.

Analysis of the Consolidated Statements of Comprehensive Income

Changes in other comprehensive income for the periods presented are primarily related to foreign currency translation adjustments and unrealized gains/(losses) on derivative instruments. The foreign currency translation adjustment changes result from the strengthening or weakening of the U.S. dollar as compared to the currencies in the countries in which we do business. Unrealized gains/(losses) on the changes in the fair value of derivative instruments are recorded within Accumulated other comprehensive income/(loss) and reclassified into earnings depending on the nature and purpose of the financial instrument, as described in Note 9. Financial Instruments of the Notes to Consolidated Financial Statements.

Analysis of the Consolidated Balance Sheets

December 31, 2022 vs. December 31, 2021

For a discussion about the changes in Cash and cash equivalents, Short-term borrowings, Current portion of long-term debt and Long-term debt, net of discount and issuance costs, see “Analysis of financial condition, liquidity and capital resources” below.

Accounts Receivable, less allowance for doubtful accounts increased primarily as a result of higher net sales in the period and the timing of customer payments, partially offset by rebate credits issued to customers and the impact of foreign exchange.

Inventories increased primarily as a result of the build-up of certain products and materials for increased demand, new product launches and to mitigate potential supply constraints, as well as the timing of material purchases and product shipments. See Notes to Consolidated Financial Statements - Note 11. Inventories.

Other current assets decreased primarily due to the deferral of a prepaid tax benefit in connection with a prepayment from a related foreign entity in Belgium and the jurisdictional netting of income taxes receivable and income taxes payable, partially offset by collateral posted related to derivative contracts and the mark-to-market adjustment of derivative instruments.

Property, plant and equipment less accumulated depreciation increased primarily as a result of capital spending, partially offset by depreciation expense. See Notes to Consolidated Financial Statements - Note 12. Property, Plant and Equipment

The increases in Operating lease right of use assets and Operating lease liabilities reflect assets acquired through new lease obligations, partially offset by lease amortization and payments. See Notes to Consolidated Financial Statements - Note 10. Leases.

Identifiable intangible assets, less accumulated amortization decreased primarily as a result of amortization expense, the impairment of certain intangible assets and the impact of foreign exchange, partially offset by intangible asset additions from acquisitions. See Notes to Consolidated Financial Statements - Note 13. Goodwill and Other Intangible Assets.

The net changes in Noncurrent deferred tax assets, Noncurrent deferred tax liabilities, Income taxes payable and Other taxes payable primarily reflect adjustments to the accrual for the income tax provision, the timing of income tax payments, the tax impact of various acquisitions and the impact of the remeasurement of deferred tax assets and liabilities as a result of changes in tax rates.

Other noncurrent assets increased primarily due to a reclassification of collateral received related to derivative contracts to Other current liabilities, the mark-to-market adjustment of derivative instruments and the purchase of investments, partially offset by the termination of certain derivative instruments in November 2022.

Accounts payable decreased as a result of the timing of vendor payments.

Dividends payable increased as a result of an increase in the dividend rate for the first quarter 2023 dividend, which was declared on December 8, 2022.

Accrued compensation and related items decreased primarily due to the payments of 2021 annual incentive bonuses and savings plan contributions to eligible employees, as well as payments for sales incentive bonuses, partially offset by the accrual of 2022 annual incentive bonuses and savings plan contributions to eligible employees, sales incentive bonus accrual and the timing of the payment of payroll taxes.

Other current liabilities increased primarily due to a reclassification of collateral received related to derivative contracts from Other noncurrent assets and the mark-to-market adjustment of derivative instruments.

Other noncurrent liabilities decreased primarily due to the fair value adjustment of contingent consideration related to certain acquisitions, a decrease in accrued pension benefits due to increases in the discount rate, a decrease in deferred compensation due to net losses from investments and the impact of foreign exchange, partially offset by the mark-to-market adjustment of derivative instruments. See Notes to Consolidated Financial Statements—Note 14. Benefit Plans.

Net increase/(decrease) in cash and cash equivalents$96$(119)$1,670$215$(1,789)

Operating activities

2022 vs. 2021

Net cash provided by operating activities was $1,912 million in 2022 compared with $2,213 million in 2021. The decrease in operating cash flows was primarily attributable to the timing of receipts and payments in the ordinary course of business, higher inventory and lower cash earnings, partially offset by proceeds from the settlement of derivative instruments.

Investing activities

2022 vs. 2021

Net cash used in investing activities was $883 million in 2022 compared with $458 million in 2021. The net cash used in investing activities for 2022 was primarily attributable to capital expenditures and acquisitions, partially offset by net proceeds from derivative instrument activity. The net cash used in investing activities for 2021 was primarily attributable to capital expenditures, acquisitions and purchase of investments, partially offset by proceeds from net proceeds from derivative instrument activity.

Financing activities

2022 vs. 2021

Net cash used in financing activities was $904 million in 2022 compared with $1,862 million in 2021. The net cash used in financing activities for 2022 was primarily attributable to the purchase of treasury shares, the payment of dividends and taxes paid on withholding shares, partially offset by proceeds from the issuance of senior notes in November 2022 and proceeds in connection with the issuance of common stock under our equity incentive plan. The net cash used in financing activities for 2021 was primarily attributable to the purchase of treasury shares, the repayment of the $300 million aggregate principal amount of our 2018 floating rate senior notes due 2021 and the $300 million aggregate principal amount of our 2018 senior notes due 2021, the payment of dividends and taxes paid on withholding shares, partially offset by proceeds in connection with the issuance of common stock under our equity incentive plan.

Analysis of financial condition, liquidity and capital resources

While we believe our cash and cash equivalents on hand, our operating cash flows and our existing financing arrangements will be sufficient to support our cash needs for the next twelve months and beyond, this may be subject to the environment in which we operate. Risks to our meeting future funding requirements include global economic conditions described in the following paragraph.

Global financial markets may be impacted by macroeconomic, business and financial volatility. As markets change, we will continue to monitor our liquidity position. While we do not anticipate it, there can be no assurance that a challenging economic environment or an economic downturn will not impact our liquidity or our ability to obtain future financing.

Selected measures of liquidity and capital resources

Certain relevant measures of our liquidity and capital resources follow:

December 31,

Cash and cash equivalents$3,581$3,485
Accounts receivable, net(a)1,2151,133

Long-term debt6,5526,592
Working capital4,3395,133
Ratio of current assets to current liabilities2.37:13.86:1

(a)    Accounts receivable are usually collected over a period of 45 to 75 days. For the years ended December 31, 2022 and 2021, the number of days that accounts receivables were outstanding have remained within this range. We regularly monitor our accounts receivable for collectability, particularly in markets where economic conditions remain uncertain. We believe that our allowance for doubtful accounts is appropriate. Our assessment is based on such factors as past due aging, historical and expected collection patterns, the financial condition of our customers, the robust nature of our credit and collection practices and the economic environment.

Credit facility and other lines of credit

In December 2022, we entered into an amended and restated revolving credit agreement with a syndicate of banks providing for a multi-year $1.0 billion senior unsecured revolving credit facility (the credit facility), which expires in December 2027. The credit facility replaced the company’s existing revolving credit facility dated as of December 21, 2016. Subject to certain conditions, we have the right to increase the credit facility up to $1.5 billion. The credit facility contains a financial covenant requiring us to not exceed a maximum total leverage ratio (the ratio of consolidated net debt as of the end of the period to consolidated Earnings Before Interest, Income Taxes, Depreciation and Amortization (EBITDA) for such period) of 3.50:1. Upon entering into a material acquisition, the maximum total leverage ratio increases to 4.00:1, and extends until the fourth full consecutive fiscal quarter ended immediately following the consummation of a material acquisition. In addition, the credit facility contains other customary covenants.

We were in compliance with all financial covenants as of December 31, 2022 and December 31, 2021. There were no amounts drawn under either credit facility as of December 31, 2022 or December 31, 2021.

We have additional lines of credit and other credit arrangements with a group of banks and other financial intermediaries for general corporate purposes. We maintain cash and cash equivalent balances in excess of our outstanding short-term borrowings. As of December 31, 2022, we had access to $51 million of lines of credit which expire at various times and are generally renewed annually. There were $2 million of borrowings outstanding related to these facilities as of December 31, 2022 and no borrowings outstanding related to these facilities as of December 31, 2021.

Domestic and international short-term funds

Many of our operations are conducted outside the U.S. The amount of funds held in the U.S. will fluctuate due to the timing of receipts and payments in the ordinary course of business and due to other reasons, such as business development activities. As part of our ongoing liquidity assessments, we regularly monitor the mix of U.S. and international cash flows (both inflows and outflows). Actual repatriation of overseas funds can result in additional U.S and local income taxes, such as U.S. state income taxes, local withholding taxes, and taxes on currency gains and losses. See Notes to Consolidated Financial Statements—Note 8. Tax Matters.

Global economic conditions

Challenging economic conditions in recent years have not had, nor do we anticipate that it will have, a significant impact on our liquidity. Due to our operating cash flows, financial assets, access to capital markets and available lines of credit and revolving credit agreements, we continue to believe that we have the ability to meet our liquidity needs for the foreseeable future. As markets change, we continue to monitor our liquidity position. There can be no assurance that a challenging economic environment or an economic downturn would not impact our ability to obtain financing in the future.

Contractual obligations

In the normal course of business, we enter into contracts and commitments that obligate us to make payments in the future. These obligations include long-term debt, including interest obligations, purchase obligations, operating lease commitments, other liabilities, benefit plan obligations and uncertain tax positions. See Notes to Consolidated Financial Statements—Note 9. Financial Instruments, Note 18. Commitments and Contingencies, Note 10. Leases, Note 6. Restructuring Charges and Other Costs Associated with Acquisitions, Cost-Reduction and Productivity Initiatives, Note 14. Benefit Plans and Note 8. Tax Matters for further information on material cash requirements from known contractual and other obligations.

Debt securities

On November 8, 2022, we issued $1.35 billion aggregate principal amount of our senior notes (2022 senior notes), with an original issue discount of $2 million. These notes are comprised of $600 million aggregate principal amount of 5.400% senior notes due 2025 and $750 million aggregate principal amount of 5.600% senior notes due 2032. On February 1, 2023, the net proceeds were used to redeem in full, upon maturity, the $1.35 billion aggregate principal amount of our 3.250% 2013 senior notes due 2023.

On August 20, 2021, we redeemed, upon maturity, the $300 million aggregate principal amount of our 2018 floating rate senior notes due 2021 and the $300 million aggregate principal amount of our 2018 senior notes due 2021.

On May 12, 2020, we issued $1.25 billion aggregate principal amount of our senior notes (2020 senior notes), with an original issue discount of $10 million. These notes are comprised of $750 million aggregate principal amount of 2.000% senior notes due 2030 and $500 million aggregate principal amount of 3.000% senior notes due 2050. On October 13, 2020, the net proceeds were used to repay the $500 million aggregate principal amount of our 3.450% 2015 senior notes due 2020 and the remainder is being used for general corporate purposes. On August 20, 2018, we issued $1.5 billion aggregate principal amount of our senior notes (2018 senior notes), with an original issue discount of $4 million. On September 12, 2017, we issued $1.25 billion aggregate principal amount of our senior notes (2017 senior notes), with an original issue discount of $7 million. On November 13, 2015, we issued $1.25 billion aggregate principal amount of our senior notes (2015 senior notes), with an original issue discount of $2 million. On January 28, 2013, we issued $3.65 billion aggregate principal amount of our senior notes (2013 senior notes) in a private placement, with an original issue discount of $10 million.

The 2013, 2015, 2017, 2018, 2020 and 2022 senior notes are governed by an indenture and supplemental indenture (collectively, the indenture) between us and Deutsche Bank Trust Company Americas, as trustee. The indenture contains certain covenants, including limitations on our and certain of our subsidiaries' ability to incur liens or engage in sale lease-back transactions. The indenture also contains restrictions on our ability to consolidate, merge or sell substantially all of our assets. In addition, the indenture contains other customary terms, including certain events of default, upon the occurrence of which, the 2013, 2015, 2017, 2018, 2020 and 2022 senior notes may be declared immediately due and payable.

Pursuant to the indenture, we are able to redeem the 2013, 2015, 2017, 2018, 2020 and 2022 senior notes of any series, in whole or in part, at any time by paying a “make whole” premium, plus accrued and unpaid interest to, but excluding, the date of redemption. Upon the occurrence of a change of control of us and a downgrade of the 2013, 2015, 2017, 2018, 2020 and 2022 senior notes below an investment grade rating by each of Moody's Investors Service, Inc. and Standard & Poor's Ratings Services, we are, in certain circumstances, required to make an offer to repurchase all of the outstanding 2013, 2015, 2017, 2018, 2020 and 2022 senior notes at a price equal to 101% of the aggregate principal amount of the 2013, 2015, 2017, 2018, 2020 and 2022 senior notes together with accrued and unpaid interest to, but excluding, the date of repurchase.

Credit ratings

Two major corporate debt-rating organizations, Moody's and S&P, assign ratings to our short-term and long-term debt. A security rating is not a recommendation to buy, sell or hold securities and the rating is subject to revision or withdrawal at any time by the rating organization. Each rating should be evaluated independently of any other rating.

The following table provides the current ratings assigned by these rating agencies to our commercial paper and senior unsecured non-credit-enhanced long-term debt:

Pension obligations

Our employees ceased to participate in the Pfizer U.S. qualified defined benefit and U.S. retiree medical plans effective December 31, 2012, and liabilities associated with our employees under these plans were retained by Pfizer. As part of the separation from Pfizer, Pfizer continued to credit certain employees' service with Zoetis generally through December 31, 2017 (or termination of employment from Zoetis, if earlier), for certain early retirement benefits with respect to Pfizer's U.S. defined benefit pension and retiree medical plans. In connection with the employee matters agreement, Zoetis is responsible for payment of three-fifths of the total cost of the service credit continuation ($38 million) for these plans. The amount of the service cost continuation payment to be paid by Zoetis to Pfizer was determined and fixed based on an actuarial assessment of the value of the grow-in benefits and will be paid in equal installments over a period of 10 years. As of December 31, 2022, there are no remaining payments due to Pfizer.

As part of the separation from Pfizer, Pfizer transferred to us the net pension obligations associated with certain international defined benefit plans. We expect to contribute a total of $5 million to these plans in 2023.

As of December 31, 2022, the supplemental savings plan liability was $43 million.

For additional information, see Notes to Consolidated Financial Statements— Note 14. Benefit Plans.

Share repurchase program

In December 2018, our Board of Directors authorized a $2.0 billion share repurchase program. This program was completed as of June 30, 2022. In December 2021, our Board of Directors authorized an additional $3.5 billion share repurchase program. As of December 31, 2022, there was $2.6 billion remaining under this authorization. Purchases of Zoetis shares may be made at the discretion of management, depending on market conditions and business needs. Share repurchases may be executed through various means, including open market or privately negotiated transactions. During 2022, 9.5 million shares were repurchased for $1.6 billion.

Off-balance sheet arrangements

In the ordinary course of business and in connection with the sale of assets and businesses, we may indemnify our counterparties against certain liabilities that may arise in connection with a transaction or that are related to activities prior to a transaction. These indemnifications typically pertain to environmental, tax, employee and/or product-related matters, and patent-infringement claims. If the indemnified party were to make a successful claim pursuant to the terms of the indemnification, we would be required to reimburse the loss. These indemnifications are generally subject to threshold amounts, specified claim periods and other restrictions and limitations. Historically, we have not paid significant amounts under these provisions and, as of December 31, 2022 and 2021, recorded amounts for the estimated fair value of these indemnifications are not material.

New accounting standards

See Note 3. Significant Accounting Policies in the Notes to Consolidated Financial Statements for discussion of recent accounting pronouncements, including the respective dates of adoption or expected adoption and effects or expected effects on our consolidated financial position, results of operations and cash flows.

A discussion regarding our financial condition and results of operations for fiscal 2020 compared to fiscal 2019 can be found under Item 7 of Part II of our Annual Report on Form 10-K for the fiscal year ended December 31, 2020, filed with the SEC on February 16, 2021 (our “2020 Annual Report”), which is available free of charge on the SEC’s website at www.sec.gov.

Overview of our business

We are a global leader in the animal health industry, focused on the discovery, development, manufacture and commercialization of medicines, vaccines, diagnostic products and services, biodevices, genetic tests and precision animal health technology. For 70 years, we have been innovating ways to predict, prevent, detect, and treat animal illness, and continue to stand by those raising and caring for animals worldwide - from livestock farmers to veterinarians and pet owners.

We manage our operations through two geographic operating segments: the United States (U.S.) and International. Within each of these operating segments, we offer a diversified product portfolio for both companion animals and livestock customers in order to capitalize on local and regional trends and customer needs. See Notes to Consolidated Financial Statements—Note 19. Segment Information.

We directly market our products to veterinarians and livestock producers located in approximately 45 countries across North America, Europe, Africa, Asia, Australia and South America, and are a market leader in nearly all of the major regions in which we operate. Through our efforts to establish an early and direct presence in many emerging markets, such as Brazil, Chile, China and Mexico, we believe we are one of the largest animal health medicines and vaccines businesses as measured by revenue across emerging markets as a whole. In markets where we do not have a direct commercial presence, we generally contract with distributors that provide logistics and sales and marketing support for our products.

We believe our investments in one of the industry’s largest sales organizations, including our extensive network of technical and veterinary operations specialists, our high-quality manufacturing and reliability of supply, and our long track record of developing products that meet customer needs, has led to enduring and valued relationships with our customers. Our research and development (R&D) efforts enable us to deliver innovative products to address unmet needs and evolve our product lines so they remain relevant for our customers.

We have approximately 300 product lines that we sell in over 100 countries for the prediction, prevention, detection and treatment of diseases and conditions that affect various companion animal and livestock species. The diversity of our product portfolio and our global operations provides stability to our overall business. For instance, in livestock, impacts on our revenue that may result from disease outbreaks or weather conditions in a particular market or region are often offset by increased sales in other regions from exports and other species as consumers shift to other proteins.

A summary of our 2021 performance compared with the comparable 2020 and 2019 periods follows:

Our operating environment

Industry

The animal health industry, which focuses on both companion animals and livestock, is a growing industry that impacts billions of people worldwide. The primary companion animal species are dogs, cats and horses. Factors influencing growth in demand for companion animal medicines, vaccines and diagnostics include:

•economic development and related increases in disposable income, particularly in many emerging markets;

•increasing pet ownership and pet owners’ commitment to the health and well-being of their pets;

•companion animals living longer;

•increasing medical treatment of companion animals; and

•advances in companion animal medicines, vaccines and diagnostics.

Table of Contents

The primary livestock species for the production of animal protein are cattle (both beef and dairy), swine, poultry, fish and sheep. Livestock health and production are essential to meeting the growing demand for animal protein of a global population. Factors influencing growth in demand for livestock medicines and vaccines include:

•human population growth and increasing standards of living, particularly in many emerging markets;

•increasing demand for improved nutrition, particularly animal protein;

•natural resource constraints, such as scarcity of arable land, fresh water and increased competition for cultivated land, resulting in fewer resources that will be available to meet an increasing demand for animal protein;

•increasing urbanization; and

•increased focus on food safety and food security.

Product development initiatives

Our future success depends on both our existing product portfolio and our pipeline of new products, including new products that we may develop through joint ventures and products that we are able to obtain through license or acquisition. We believe we are an industry leader in animal health R&D, with a track record of generating new products and product lifecycle innovation. The majority of our R&D programs focus on product lifecycle innovation, which is defined as R&D programs that leverage existing animal health products by adding new species or claims, achieving approvals in new markets or creating new combinations and reformulations. In addition to traditional medicines and vaccines, we develop products across additional categories to address the needs of veterinarians and producers to predict, prevent, detect and treat conditions in both companion animals and livestock, including products and services in diagnostics, genetics, precision animal health and digital and data analytics.

Perceptions of product quality, safety and reliability

We believe that animal health customers value high-quality manufacturing and reliability of supply. The importance of quality and safety concerns to pet owners, veterinarians and livestock producers also contributes to animal health brand loyalty, which often continues after the loss of patent-based and regulatory exclusivity. We depend on positive perceptions of the safety and quality of our products by our customers, veterinarians and end-users.

In addition, negative beliefs about animal health products generally could impact demand for our products. For example, the issue of the potential transfer of increased antibacterial resistance in bacteria from food-producing animals to human pathogens, and the causality of that transfer, continue to be the subject of global scientific and regulatory discussion. Antibacterials refer to small molecules that can be used to treat or prevent bacterial infections and are a sub-categorization of the products that make up our anti-infectives and medicated feed additives portfolios. In some countries, this issue has led to government restrictions and bans on the use of specific antibacterials in some food-producing animals, regardless of the route of administration (in feed or injectable). These restrictions are more prevalent in countries where animal protein is plentiful and governments are willing to take action even when there is scientific uncertainty. In addition, consumer preferences in some markets have impacted the use of antibacterials in food producing animals. Such restrictions and consumer preferences in some cases may negatively impact sales of our antibacterial products, but in other instances may increase sales of our products that can be used as antibacterial alternatives. Our total revenue attributable to antibacterials for livestock was approximately $1.1 billion for the year ended December 31, 2021.

Similarly, concerns regarding greenhouse gas emissions and other potential environmental impacts of livestock production have led to some consumers opting to limit or avoid consuming animal products. However, we believe the impact of this trend is limited as the livestock industry is still expected to continue to grow in order to feed a growing global population.

Changing distribution channels for companion animal products

In most markets, companion animal owners typically purchase their animal health products directly from veterinarians. However, in the U.S. and certain other markets, companion animal owners increasingly have the option to purchase animal health products from sources other than veterinarians, such as Internet-based retailers, “big-box” retail stores or other over-the-counter distribution channels. This trend has been demonstrated by the shift away from the veterinarian distribution channel in the sale of flea and tick products in recent years and has been accelerated by the increase in e-commerce during the COVID-19 pandemic. We believe the ability of pet owners to purchase our products online and from retail stores may increase pet owner compliance and result in increased sales, particularly in the near term. However, over time, we may be unable to sustain our current margins due to the increased purchasing power of such retailers as compared to traditional veterinary practices.

In addition, this trend could negatively impact the sales of products we primarily sell through the veterinarian distribution channel, as any decrease in visits to veterinarians by companion animal owners could reduce our market share and sales of such products. A reduction in the number of pet owners who purchase our products directly from their veterinarian could also lead to increased use of generic alternatives to our products or the increased substitution of our products with other animal health products or human health products if such other products are deemed to be lower-cost alternatives.

The overall economic environment

In addition to industry-specific factors, we, like other businesses, face challenges related to global economic conditions. Growth in both the livestock and companion animal sectors is driven by overall economic development and related growth, particularly in many emerging markets. In the past, certain of our customers and suppliers have been affected directly by economic downturns, which decreased the demand for our products and, in some cases, hindered our ability to collect amounts due from customers.

The cost of medicines and vaccines to our livestock producer customers is small relative to other production costs, including feed, and the use of these products is intended to improve livestock producers’ economic outcomes. As a result, demand for our products has historically been more stable than demand for other production inputs. Similarly, industry sources have reported that pet owners indicated a preference for reducing spending on other aspects of their lifestyle, including entertainment, clothing and household goods, before reducing spending on pet care. Each of these factors, plus our broad and innovative portfolio, contributes to our ability to incorporate inflationary challenges into our product pricing and mitigate the impact on our results. While these factors have mitigated the impact of prior downturns in the global economy, future economic

challenges, including inflation, could increase cost sensitivity among our customers, which may result in reduced demand for our products, which could have a material adverse effect on our operating results and financial condition.

Competition

The animal health industry is highly competitive. Although our business is the largest based on revenue in the animal health industry (which includes medicines, vaccines and diagnostics), we face competition in the regions in which we operate. Principal methods of competition vary depending on the particular region, species, product category or individual product. Some of these methods include new product development, quality, price, service and promotion to veterinary professionals, pet owners and livestock producers. Our competitors include standalone animal health businesses and the animal health businesses of large pharmaceutical companies. In recent years, there has been an increase in consolidation in the animal health industry. There are also many start-up companies working in the animal health area. In addition to competition from established market participants, there could be new entrants to the animal health medicines, vaccines and diagnostics industry in the future. We also compete with companies that produce generic products, following our products’ loss of exclusivity in a given market. For example, Draxxin currently competes with generic products in key markets including the U.S., Europe, Canada, Mexico and Australia. For more information regarding the generic competition we currently have and expect to encounter as patents on certain of our key products expire, see Item 1. Business – Intellectual Property.

Weather conditions, climate change and the availability of natural resources

The animal health industry and demand for many of our animal health products in a particular region are affected by weather conditions, as usage of our products follows varying weather patterns and weather-related pressures from pests, such as ticks. As a result, we may experience regional and seasonal fluctuations in our results of operations.

In addition, veterinary hospitals and practitioners depend on visits from and access to the animals under their care. Veterinarians’ patient volume and ability to operate could be adversely affected if they experience prolonged snow, ice or other severe weather conditions, particularly in regions not accustomed to sustained inclement weather. Furthermore, weather conditions, including excessive cold or heat, natural disasters and other events, could negatively impact our livestock customers by impairing the health or growth of their animals or the production or availability of feed, as well as disrupting their normal operations. For example, livestock producers depend on the availability of natural resources, including large supplies of fresh water. Their animals’ health and their ability to operate could be adversely affected if they experience a shortage of fresh water due to human population growth, climate change or floods, droughts or other weather conditions. In the event of adverse weather conditions, climate-change related impacts or a shortage of fresh water, veterinarians and livestock producers may purchase less of our products.

For example, drought conditions could negatively impact, among other things, the supply of corn and the availability of grazing pastures. A decrease in harvested corn results in higher corn prices, which could negatively impact the profitability of livestock producers of cattle, pork and poultry. Higher corn prices and reduced availability of grazing pastures contribute to reductions in herd or flock sizes that in turn result in less spending on animal health products. As such, a prolonged drought could have a material adverse impact on our operating results and financial condition.

Adverse weather conditions, natural disasters and climate change may also impact the aquaculture business. Changes in water temperatures could affect the timing of reproduction and growth of various fish species, as well as trigger the outbreak of certain waterborne diseases.

Uncertainty Relating to COVID-19

We continue to closely monitor the impact of the coronavirus (COVID-19) pandemic and the resulting global recession on all aspects of our business across geographies, including how it has and may continue to impact our customers, workforce, suppliers and vendors. Although we are unable to fully predict the impact that the COVID-19 pandemic will ultimately have on our future financial position and operating results, we continue to monitor the potential effects, including impacts on our supply chain, the effect on customer demand, and changes to our operations. We cannot predict the impact that the COVID-19 pandemic will have on our customers, vendors and suppliers; however, any material effect on these parties could adversely impact us.

The situation surrounding COVID-19 remains fluid, and we will continue to actively monitor the situation and may take actions that alter our business operations that we determine are in the best interests of our workforce, customers, vendors, suppliers, and other stakeholders, or as required by federal, state, or local authorities.

For further information regarding the impact of COVID-19 on the Company, see Item 1A, Risk Factors in this Annual Report on Form 10-K.

Disease Outbreaks

Sales of our livestock products have in the past, and may in the future be, adversely affected by the outbreak of disease carried by animals. Outbreaks of disease may reduce regional or global sales of particular animal-derived food products or result in reduced exports of such products, either due to heightened export restrictions or import prohibitions, which may reduce demand for our products. Also, the outbreak of any highly contagious disease near our main production sites could require us to immediately halt production of our products at such sites or force us to incur substantial expenses in procuring raw materials or products elsewhere. Alternatively, sales of products that treat specific disease outbreaks may increase.

Manufacturing and supply

In order to sell our products, we must be able to produce and ship our products in sufficient quantities. Many of our products involve complex manufacturing processes and are sole-sourced from certain manufacturing sites. Minor deviations in our manufacturing or logistical processes, such as temperature excursions or improper package sealing, could result in delays, inventory shortages, unanticipated costs, product recalls, product liability and/or regulatory action. In addition, a number of factors could cause production interruptions that could result in launch delays, inventory shortages, recalls, unanticipated costs or issues with our agreements under which we supply third parties.

In 2021, we experienced isolated supply challenges for Librela, Solensia and some of our other products, resulting from strong demand as well as competition for manufacturing inputs with human health vaccine development during the pandemic. Some of these challenges are expected to continue in 2022, but are being managed by our global manufacturing network through certain supply chain optimizations, controlled launches for new products in additional markets and customer coordination.

40 |

Table of Contents

Our manufacturing network may be unable to meet the demand for our products or we may have excess capacity if demand for our products changes. The unpredictability of a product's regulatory or commercial success or failure, the lead time necessary to construct highly technical and complex manufacturing sites, and shifting customer demand increase the potential for capacity imbalances.

Foreign exchange rates

Significant portions of our revenue and costs are exposed to changes in foreign exchange rates. Our products are sold in more than 100 countries and, as a result, our revenue is influenced by changes in foreign exchange rates. For the year ended December 31, 2021, approximately 44% of our revenue was denominated in foreign currencies. We seek to manage our foreign exchange risk, in part, through operational means, including managing same-currency revenue in relation to same-currency costs and same-currency assets in relation to same-currency liabilities. As we operate in multiple foreign currencies, including the Australian dollar, Brazilian real, British pound, Canadian dollar, Chinese yuan, euro and other currencies, changes in those currencies relative to the U.S. dollar will impact our revenue, cost of goods and expenses, and consequently, net income. Exchange rate fluctuations may also have an impact beyond our reported financial results and directly impact operations. These fluctuations may affect the ability to buy and sell our goods and services between markets impacted by significant exchange rate variances. For the year ended December 31, 2021, approximately 56% of our total revenue was in U.S. dollars. Our year-over-year total revenue growth was favorably impacted by 1% from changes in foreign currency values relative to the U.S. dollar.

Our growth strategies

We seek to enhance the health of animals and to bring solutions to our customers who raise and care for them. We have a global presence in both developed and emerging markets and across eight core species. We intend to grow our business by pursuing the following core strategies:

•drive innovative growth - We seek to deliver new products and solutions as well as lifecycle innovations across the continuum of care that spans from disease prediction and prevention to detection and treatment. We are focused on innovating across vaccines, pharmaceuticals, diagnostics, genetics, biodevices, and other product segments, and across all core species. Where appropriate, we complement internal R&D programs with external innovations;

•enhance customer experience - We believe that delighting our customers with compelling and personalized experiences that enable them to provide the best care for animals is critical for our success. We are focused on providing greater value to our customers through the integration and connectedness of our portfolio and by reducing frictions in the way they engage with us and our products and solutions;

•lead in digital and data analytics - We believe that healthcare insights enabled by data and digital technology and complemented with our comprehensive portfolio of products and solutions will be critical in enhancing care for animals and improving livestock productivity;

•cultivate a high-performing organization - We view the strength of our leadership team and our talented colleagues around the world as a critical component of our past and future success. We are committed to continuing to be a company our colleagues can be proud of and to attracting, retaining and developing the best, most diverse talent in the industry. We are further committed to sustaining a diverse, equitable and inclusive work environment for our colleagues; and

•champion a healthier, more sustainable future - As the world’s leading animal health company, our business purpose is well aligned with our social purpose. We strive to make a meaningful difference in society through the three pillars of our sustainability approach: (1) by caring and collaborating with our customers, colleagues, and communities, and the animals that depend on them by improving access to care for animals, by creating a diverse, equitable, and inclusive work environment, and by supporting the veterinary profession; (2) by leveraging our innovation capabilities to develop solutions that improve productivity, keep animals healthy, and fight emerging infectious diseases; and (3) by taking actions to protect our planet that reduce our footprint on the environment.

Components of revenue and costs and expenses

Our revenue, costs and expenses are reported for the year ended December 31 for each year presented, except for operations outside the U.S., for which the financial information is included in our consolidated financial statements for the fiscal year ended November 30 for each year presented.

Revenue

Our revenue is primarily derived from our diversified product portfolio of medicines, vaccines and diagnostic products and services used to treat and protect companion animals and livestock. Generally, our products are promoted to veterinarians and livestock producers by our sales organization which includes sales representatives and technical and veterinary operations specialists, and then sold directly by us or through distributors, retailers or e-commerce outlets. The depth of our product portfolio enables us to address the varying needs of customers in different species and geographies. In 2021, our two top-selling products, Apoquel and Simparica/Simparica Trio, each contributed approximately 10% of our revenue, and combined with our next three top-selling products, Revolution/Revolution Plus/Stronghold, Cytopoint and the ceftiofur line, these five contributed approximately 33% of our revenue. Our ten top-selling product lines contributed 47% of our revenue. For additional information regarding our products, including descriptions of our product lines that each represented approximately 1% or more of our revenue in 2021, see Item 1. Business—Products.

Costs and expenses

Costs of sales consist primarily of cost of materials, facilities and other infrastructure used to manufacture our medicine and vaccine products, as well as costs to operate our reference labs and royalty expenses associated with the intellectual property of our products, when relevant.

Selling, general and administrative (SG&A) expenses consist of, among other things, the internal and external costs of marketing, promotion, advertising and shipping and handling as well as certain costs related to business technology, facilities, legal, finance, human resources, business development, public affairs and procurement.

41 |

Table of Contents

Research and development (R&D) expenses consist primarily of project costs specific to new product R&D and product lifecycle innovation, overhead costs associated with R&D operations and investments that support local market clinical trials for approved indications and expenses related to regulatory approvals for our products. We do not disaggregate R&D expenses by research stage or by therapeutic area for purposes of managing our business.

Amortization of intangible assets consists primarily of the amortization expense for identifiable finite-lived intangible assets that have been acquired through business combinations. These assets consist of, but are not limited to, developed technology, brands and trademarks.

Restructuring charges and certain acquisition-related costs consist of all restructuring charges (those associated with acquisition activity and those associated with cost reduction/productivity initiatives), as well as costs associated with acquiring and integrating businesses. Restructuring charges are associated with employees, assets and activities that will not continue in the company. Acquisition-related costs are associated with acquiring and integrating acquired businesses, such as Abaxis in 2018, and may include transaction costs and expenditures for consulting and the integration of systems and processes.

Other (income)/deductions—net consists of various items, primarily net (gains)/losses on asset disposals, interest income, royalty-related income, foreign exchange translation (gains)/losses and certain asset impairment charges.

Significant accounting policies and application of critical accounting estimates

In presenting our financial statements in conformity with U.S. GAAP, we are required to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenue, costs and expenses and related disclosures. For a description of our significant accounting policies, see Notes to Consolidated Financial Statements— Note 3. Significant Accounting Policies.

We believe that the following accounting policies are critical to an understanding of our consolidated financial statements as they require the application of the most difficult, subjective and complex judgments and, therefore, could have the greatest impact on our financial statements: (i) fair value; (ii) revenue; (iii) asset impairment reviews; and (iv) contingencies.

Below are some of our more critical accounting estimates. See also Notes to Consolidated Financial Statements— Note 3. Significant Accounting Policies: Estimates and Assumptions for a discussion about the risks associated with estimates and assumptions.

Fair value

For a discussion about the application of fair value to our long-term debt and financial instruments, see Notes to Consolidated Financial Statements—

Note 9. Financial Instruments.

For a discussion about the application of fair value to our business combinations, see Notes to Consolidated Financial Statements— Note 3. Significant Accounting Policies: Fair Value.

For a discussion about the application of fair value to our asset impairment reviews, see Asset impairment reviews below.

Revenue

Our gross product revenue is subject to deductions that are generally estimated and recorded in the same period that the revenue is recognized and primarily represents sales returns and revenue incentives. For example:

•for sales returns, we perform calculations in each market that incorporate the following, as appropriate: local returns policies and practices; returns as a percentage of revenue; an understanding of the reasons for past returns; estimated shelf life by product; an estimate of the amount of time between shipment and return or lag time; and any other factors that could impact the estimate of future returns, product recalls, discontinuation of products or a changing competitive environment; and

•for revenue incentives, we use our historical experience with similar incentives programs to estimate the impact of such programs on revenue.

If any of our ratios, factors, assessments, experiences or judgments are not indicative or accurate predictors of our future experience, our results could be materially affected. Although the amounts recorded for these revenue deductions are dependent on estimates and assumptions, historically our adjustments to actual results have not been material. The sensitivity of our estimates can vary by program, type of customer and geographic location.

Amounts recorded for revenue deductions can result from a complex series of judgments about future events and uncertainties and can rely on estimates and assumptions. For further information about the risks associated with estimates and assumptions, see Notes to Consolidated Financial Statements— Note 3. Significant Accounting Policies: Estimates and Assumptions.

Asset impairment reviews

We review all of our long-lived assets for impairment indicators throughout the year and we perform detailed testing whenever impairment indicators are present. In addition, we perform impairment testing for goodwill and indefinite-lived intangible assets at least annually. When necessary, we record charges for impairments of long-lived assets for the amount by which the fair value is less than the carrying value of these assets.

Our impairment review processes are described below and in Notes to Consolidated Financial Statements— Note 3. Significant Accounting Policies: Amortization of Intangible Assets, Depreciation and Certain Long-Lived Assets and, for deferred tax assets, in Note 3. Significant Accounting Policies: Deferred Tax Assets and Liabilities and Income Tax Contingencies.

Examples of events or circumstances that may be indicative of impairment include:

•a significant adverse change in the extent or manner in which an asset is used. For example, restrictions imposed by the regulatory authorities could affect our ability to manufacture or sell a product; and

42 |

Table of Contents

•a projection or forecast that demonstrates losses or reduced profits associated with an asset. This could result, for example, from the introduction of a competitor’s product that results in a significant loss of market share or the inability to achieve the previously projected revenue growth, or from the lack of acceptance of a product by customers.

For finite-lived identifiable intangible assets, such as developed technology rights, and for other long-lived assets, such as property, plant and equipment, whenever impairment indicators are present, we calculate the undiscounted value of the projected cash flows associated with the asset, or asset group, and compare this estimated amount to the carrying amount. If the carrying amount is found to be greater, we record an impairment loss for the excess of book value over fair value. In addition, in all cases of an impairment review, we re-evaluate the remaining useful lives of the assets and modify them, as appropriate.

Our impairment reviews of most of our long-lived assets depend on the determination of fair value, as defined by U.S. GAAP, and these judgments can materially impact our results of operations. A single estimate of fair value can result from a complex series of judgments about future events and uncertainties and can rely on estimates and assumptions. For information about the risks associated with estimates and assumptions, see Notes to Consolidated Financial Statements—Note 3. Significant Accounting Policies: Estimates and Assumptions.

Intangible assets other than goodwill

We test indefinite-lived intangible assets for impairment at least annually, or more frequently if impairment indicators exist, by first assessing qualitative factors to determine whether it is more likely than not that the fair value of the indefinite-lived intangible asset is less than its carrying amount. If we conclude it is more likely than not that the fair value is less than the carrying amount, a quantitative test that compares the fair value of the indefinite-lived intangible asset with its carrying value is performed. If the fair value is less than the carrying amount, an impairment loss is recognized. Impairments of identifiable intangible assets other than goodwill, are recorded in Restructuring charges and certain acquisition-related costs and Other (income)/deductions—net, as applicable. We did not have any significant intangible asset impairment charges for the years ended December 31, 2021, 2020 and 2019.

When we are required to determine the fair value of intangible assets other than goodwill, we use an income approach, specifically the multi-period excess earnings method, also known as the discounted cash flow method. We start with a forecast of all the expected net cash flows associated with the asset, which includes the application of a terminal value for indefinite-lived assets, and then we apply an asset-specific discount rate to arrive at a net present value amount. Some of the more significant estimates and assumptions inherent in this approach include: the amount and timing of the projected net cash flows, which includes the expected impact of competitive, legal and/or regulatory forces on the projections, the impact of technological risk associated with IPR&D assets, as well as the selection of a long-term growth rate; the discount rate, which seeks to reflect the risks inherent in the projected cash flows; foreign currency fluctuations; and the effective tax rate, which seeks to incorporate the geographic diversity of the projected cash flows.

While all identifiable intangible assets can be impacted by events and thus lead to impairment, in general, identifiable intangible assets that are at the highest risk of impairment include IPR&D assets (approximately $88 million as of December 31, 2021). IPR&D assets are higher-risk assets because R&D is an inherently risky activity.

For a description of our accounting policy, see Notes to Consolidated Financial Statements—Note 3. Significant Accounting Policies: Amortization of Intangible Assets, Depreciation and Certain Long-Lived Assets.

Goodwill

Goodwill represents the excess of the consideration transferred over the fair value of net assets of businesses purchased and is assigned to reporting units. We test goodwill for impairment on at least an annual basis, or more frequently if necessary, either by assessing qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount or by performing a periodic quantitative assessment.

Factors considered in the qualitative assessment include general macroeconomic conditions, conditions specific to the industry and market, cost factors which could have a significant effect on earnings or cash flows, the overall financial performance of the reporting unit and whether there have been sustained declines in our share price. Additionally, we evaluate the extent to which the fair value exceeded the carrying value of the reporting unit at the date of the last quantitative assessment performed.

When performing a quantitative assessment to test for goodwill impairment we utilize the income approach, which is forward-looking, and relies primarily on internal forecasts. Within the income approach, the method that we use is the discounted cash flow method. We start with a forecast of all the expected net cash flows associated with the reporting unit, which includes the application of a terminal value, and then apply a reporting unit-specific discount rate to arrive at a net present value. Some of the more significant estimates and assumptions inherent in this approach include: the amount and timing of the projected net cash flows, which includes the expected impact of technological risk and competitive, legal and/or regulatory forces on the projections, as well as the selection of a long-term growth rate; the discount rate, which seeks to reflect the various risks inherent in the projected cash flows; and the effective tax rate, which seeks to incorporate the geographic diversity of the projected cash flows.

We test goodwill for impairment on at least an annual basis, or more frequently if necessary, either by assessing qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount or by performing a periodic quantitative assessment. In 2021 and 2020, we performed a periodic quantitative impairment assessment as of September 30, 2021 and 2020, respectively, which did not result in the impairment of goodwill associated with any of our reporting units.

For all of our reporting units, there are a number of future events and factors that may impact future results and that could potentially have an impact on the outcome of subsequent goodwill impairment testing. For a list of these factors, see Forward-looking statements and factors that may affect future results.

Non-GAAP financial measures

We report information in accordance with U.S. generally accepted accounting principles (GAAP). Management also measures performance using non-GAAP financial measures that may exclude certain amounts from the most directly comparable GAAP measure. Despite the importance of these measures to management in goal setting and performance measurement, non-GAAP financial measures have no standardized meaning prescribed by U.S. GAAP and, therefore, have limits in their usefulness to investors and may not be comparable to the calculation of similar measures of other companies. We present certain identified non-GAAP measures solely to provide investors with useful information to more fully understand how management assesses performance.

Operational Growth

We believe that it is important to not only understand overall revenue and earnings growth, but also “operational growth.” Operational growth is a non-GAAP financial measure defined as revenue or earnings growth excluding the impact of foreign exchange. This measure provides information on the change in revenue and earnings as if foreign currency exchange rates had not changed between the current and prior periods to facilitate a period-to-period comparison. We believe this non-GAAP measure provides a useful comparison to previous periods for the company and investors, but should not be viewed as a substitute for U.S. GAAP reported growth.

Adjusted Net Income and Adjusted Earnings Per Share

Adjusted net income and the corresponding adjusted earnings per share (EPS) are non-GAAP financial measures of performance used by management. We believe these financial measures are useful supplemental information to investors when considered together with our U.S. GAAP financial measures. We report adjusted net income to portray the results of our major operations, and the discovery, development, manufacture and commercialization of our products, prior to considering certain income statement elements. We define adjusted net income and adjusted EPS as net income attributable to Zoetis and EPS before the impact of purchase accounting adjustments, acquisition-related costs and certain significant items.

We recognize that, as an internal measure of performance, the adjusted net income and adjusted EPS measures have limitations, and we do not restrict our performance management process solely to these metrics. A limitation of the adjusted net income and adjusted EPS measures is that they provide a view of our operations without including all events during a period, such as the effects of an acquisition or amortization of purchased intangibles, and do not provide a comparable view of our performance to other companies. The adjusted net income and adjusted EPS measures are not, and should not be viewed as, a substitute for U.S. GAAP reported net income attributable to Zoetis and reported EPS. See the Adjusted Net Income section below for more information.

Operating Segment Results

Beginning in the first quarter of 2021, certain costs associated with information technology that specifically support our global manufacturing operations, which were previously reported in Other unallocated, are now reported in Corporate. In addition, in the first quarter of 2021, the company realigned certain management responsibilities. These changes did not impact the determination of our operating segments, however they resulted in the reallocation of certain costs between segments. These changes primarily include the following: (i) certain diagnostics costs, which were previously reported in Corporate, are now reported in our U.S. results; and (ii) certain other miscellaneous costs, which were previously reported in our U.S. results, are now reported in Corporate.

In 2020, the company realigned certain management responsibilities. These changes did not impact the determination of our operating segments, however they resulted in the reallocation of certain costs between segments. These changes primarily include the following: (i) R&D costs related to our aquaculture business, which were previously reported in our international commercial segment, are now reported in Other business activities; (ii) certain other miscellaneous costs, which were previously reported in international commercial segment results, are now reported in Corporate; and (iii) certain diagnostics and other miscellaneous costs, which were previously reported in our U.S. results, are now reported in Corporate.

2021 vs. 2020

U.S. operating segment

U.S. segment revenue increased by $485 million, or 14%, in 2021 compared with 2020, of which $599 million resulted from growth in companion animal products, offset by a $114 million decline in livestock products.

•Companion animal revenue growth was driven primarily by increased sales of parasiticides including Simparica Trio, as well as the ProHeart and Revolution/Stronghold franchises. In-line product growth benefited from increased sales of our key dermatology portfolio, vaccines and diagnostics products.

•Livestock revenue declined due to cattle, poultry and swine. Cattle product sales declined as a result of increased generic competition and challenges in the beef and dairy end-markets due to rising input costs. The poultry portfolio declined as a result of the expanded use of lower cost alternatives and smaller flock sizes reducing disease pressure, as well as generic competition. The decline in swine product sales was primarily due to pricing pressures on our anti-infective and vaccine portfolio and a non-recurring government purchase in the prior year.

U.S. segment earnings increased by $330 million, or 15%, in 2021 compared with 2020, primarily due to revenue and gross margin growth, partially offset by higher operating expenses.

International operating segment

International segment revenue increased by $617 million, or 20%, in 2021 compared with 2020. Operational revenue growth was $519 million, or 17%, reflecting growth of $383 million in companion animal products and $136 million in livestock products.

•Companion animal operational revenue growth resulted primarily from increased sales of our parasiticide products including the Simparica/Simparica Trio and Revolution/Stronghold franchises. Also contributing to growth were our key dermatology portfolio, vaccine products, the recent launches of our mAb therapies, Librela and Solensia, and diagnostics products. Growth across the broader in-line portfolio benefited from increased pet ownership and standards of care.

•Livestock operational revenue growth was primarily driven by increased sales in cattle, swine and fish. Growth in cattle product sales was mainly due to the effect of marketing campaigns, key account penetration and favorable export market conditions in Brazil and favorable conditions in other emerging markets. Sales of swine products grew as a result of expanding pork production in the wake of African Swine Fever in China in the first half of the year. Fish growth was due to an increase in sales of the Alpha Flux sea lice treatment product, an increase in vaccine sales in key salmon markets and the 2020 acquisition of Fish Vet Group.

•Additionally, International segment revenue was favorably impacted by foreign exchange which increased revenue by approximately $98 million, or 3%, primarily driven by the euro, Chinese yuan, Australian dollar and Canadian dollar, partially offset by the Brazilian real and Argentinian peso.

International segment earnings increased by $401 million, or 26%, in 2021 compared with 2020. Operational earnings growth was $324 million, or 21%, primarily due to revenue and gross margin growth, partially offset by higher operating expenses.

Other business activities

Other business activities includes our CSS contract manufacturing results, our human health business and expenses associated with our dedicated veterinary medicine R&D organization, research alliances, U.S. regulatory affairs and other operations focused on the development of our products. Other R&D-related costs associated with non-U.S. market and regulatory activities are generally included in the International segment.

2021 vs. 2020

Other business activities net loss increased by $34 million, or 9%, in 2021 compared with 2020, reflecting an increase in R&D costs due to an increase in compensation-related costs, an increase in project investments and unfavorable foreign exchange.

Reconciling items

Reconciling items include certain costs that are not allocated to our operating segments results, such as costs associated with the following:

•Corporate, which includes certain costs associated with information technology, facilities, legal, finance, human resources, business development and communications, among others. These costs also include certain compensation costs, certain procurement costs, and other miscellaneous operating expenses that are not charged to our operating segments, as well as interest income and expense;

•Certain transactions and events such as (i) Purchase accounting adjustments, which includes expenses associated with the amortization of fair value adjustments to inventory, intangible assets and property, plant and equipment; (ii) Acquisition-related activities, which includes costs for acquisition and integration; and (iii) Certain significant items, which includes non-acquisition-related restructuring charges, certain asset impairment charges, certain legal and commercial settlements, and costs associated with cost reduction/productivity initiatives; and

•Other unallocated, which includes (i) certain overhead expenses associated with our global manufacturing operations not charged to our operating segments; (ii) certain costs associated with finance that specifically support our global manufacturing operations; (iii) certain supply chain and global logistics costs; and (iv) certain procurement costs.

2021 vs. 2020

Corporate expenses increased by $173 million, or 20%, in 2021 compared with 2020, primarily due to increases in certain compensation-related costs, investments in information technology, charitable contributions and unfavorable foreign exchange. Lower interest income was offset by lower interest expense.

49 |

Table of Contents

Other unallocated expenses increased by $31 million, or 11%, in 2021 compared with 2020, primarily due to higher manufacturing costs, higher freight charges and unfavorable foreign exchange, partially offset by lower inventory obsolescence, scrap and other charges.

Adjusted net income

General description of adjusted net income (a non-GAAP financial measure)

Adjusted net income is an alternative view of performance used by management, and we believe that investors’ understanding of our performance is enhanced by disclosing this performance measure. The adjusted net income measure is an important internal measurement for us. Additionally, we measure our overall performance on this basis in conjunction with other performance metrics. The following are examples of how the adjusted net income measure is utilized:

•senior management receives a monthly analysis of our operating results that is prepared on an adjusted net income basis;

•our annual budgets are prepared on an adjusted net income basis; and

•other goal setting and performance measurements.

Purchase accounting adjustments

Adjusted net income is calculated prior to considering certain significant purchase accounting impacts that result from business combinations and net asset acquisitions. These impacts, primarily associated with the acquisition of Abaxis (acquired in July 2018), the Pharmaq business (acquired in November 2015), certain assets of Abbott Animal Health (acquired in February 2015), King Animal Health (acquired in 2011), Fort Dodge Animal Health (acquired in 2009), and Pharmacia Animal Health business (acquired in 2003), include amortization related to the increase in fair value of the acquired finite-lived intangible assets and depreciation related to the increase/decrease to fair value of the acquired fixed assets. Therefore, the adjusted net income measure includes the revenue earned upon the sale of the acquired products without considering the aforementioned significant charges.

While certain purchase accounting adjustments can occur through 20 or more years, this presentation provides an alternative view of our performance that is used by management to internally assess business performance. We believe the elimination of amortization attributable to acquired intangible assets provides management and investors an alternative view of our business results by providing a degree of parity to internally developed intangible assets for which R&D costs previously have been expensed.

A completely accurate comparison of internally developed intangible assets and acquired intangible assets cannot be achieved through adjusted net income. These components of adjusted net income are derived solely from the impact of the items listed above. We have not factored in the impact of any other differences in experience that might have occurred if we had discovered and developed those intangible assets on our own, and this approach does not intend to be representative of the results that would have occurred in those circumstances. For example, our R&D costs in total, and in the periods presented, may have been different; our speed to commercialization and resulting revenue, if any, may have been different; or our costs to manufacture may have been different. In addition, our marketing efforts may have been received differently by our customers. As such, in total, there can be no assurance that our adjusted net income amounts would have been the same as presented had we discovered and developed the acquired intangible assets.

Acquisition-related costs

Adjusted net income is calculated prior to considering transaction and integration costs associated with significant business combinations or net asset acquisitions because these costs are unique to each transaction and represent costs that were incurred to acquire and integrate certain businesses as a result of the acquisition decision. We have made no adjustments for the resulting synergies.

We believe that viewing income prior to considering these charges provides investors with a useful additional perspective because the significant costs incurred in a business combination result primarily from the need to eliminate duplicate assets, activities or employees––a natural result of acquiring a fully integrated set of activities. For this reason, we believe that the costs incurred to convert disparate systems, to close duplicative facilities or to eliminate duplicate positions (for example, in the context of a business combination) can be viewed differently from those costs incurred in the ordinary course of business.

The integration costs associated with a business combination may occur over several years, with the more significant impacts generally ending within three years of the transaction. Because of the need for certain external approvals for some actions, the span of time needed to achieve certain restructuring and integration activities can be lengthy. For example, due to the regulated nature of the animal health medicines and vaccines business, the closure of excess facilities can take several years, as all manufacturing changes are subject to extensive validation and testing and must be approved by the FDA and/or other regulatory authorities.

Certain significant items

Adjusted net income is calculated excluding certain significant items. Certain significant items represent substantive, unusual items that are evaluated on an individual basis. Such evaluation considers both the quantitative and the qualitative aspect of their unusual nature. Unusual, in this context, may represent items that are not part of our ongoing business; items that, either as a result of their nature or size, we would not expect to occur as part of our normal business on a regular basis; items that would be nonrecurring; or items that relate to products that we no longer sell. While not all-inclusive, examples of items that could be included as certain significant items would be costs related to a major non-acquisition-related restructuring charge and associated implementation costs for a program that is specific in nature with a defined term, such as those related to our non-acquisition-related cost-reduction and productivity initiatives; amounts related to disposals of products or facilities that do not qualify as discontinued operations as defined by U.S. GAAP; certain intangible asset impairments; adjustments related to the resolution of certain tax positions; significant currency devaluation; the impact of adopting certain significant, event-driven tax legislation; costs related to our CEO transition in fiscal 2020; or charges related to legal matters. See Notes to Consolidated Financial Statements— Note 18. Commitments and Contingencies. Our normal, ongoing defense costs or settlements of and accruals on legal matters made in the normal course of our business would not be considered certain significant items.

(a)    The effective tax rate on adjusted pretax income is 18.6%, 18.3% and 18.2% in 2021, 2020 and 2019, respectively.

The higher effective tax rate for 2021, compared with 2020, was primarily attributable to (i) changes in the jurisdictional mix of earnings, which includes the impact of the location of earnings, repatriation costs, operating fluctuations in the normal course of business and the impact of non-deductible and non-taxable items. In addition, 2021 includes a tax benefit related to foreign-derived intangible income, (ii) a $7 million and $20 million net discrete tax benefit recorded in 2021 and 2020, respectively, related to changes in other tax items, (iii) a $24 million and $29 million discrete tax benefit recorded in 2021 and 2020, respectively, related to the excess tax benefits for share-based payments, and (iv) a $1 million discrete tax expense and a $3 million discrete tax benefit recorded in 2021 and 2020, respectively, related to a remeasurement of deferred tax assets and liabilities as a result of changes in statutory tax rates, partially offset by an $8 million and $4 million net discrete tax benefit recorded in 2021 and 2020, respectively, related to the effective settlement of certain issues with tax authorities.

The higher effective tax rate for 2020, compared with 2019, was primarily attributable to (i) changes in the jurisdictional mix of earnings, which includes the impact of the location of earnings, repatriation costs, operating fluctuations in the normal course of business and the impact of non-deductible and non-taxable items, (ii) an $18 million net discrete tax benefit recorded in 2019 related to changes in valuation allowances, and (iii) a $4 million and $10 million net discrete tax benefit recorded in 2020 and 2019, respectively, related to the effective settlement of certain issues with tax authorities, partially offset by (i) a $20 million and $4 million net discrete tax benefit recorded in 2020 and 2019, respectively, related to changes in other tax items, and (ii) a $29 million and $20 million discrete tax benefit recorded in 2020 and 2019, respectively, related to the excess tax benefits for share-based payments.

Analysis of the Consolidated Statements of Comprehensive Income

Substantially all changes in other comprehensive income for the periods presented are related to foreign currency translation adjustments. These changes result from the strengthening or weakening of the U.S. dollar as compared to the currencies in the countries in which we do business. The gains and losses associated with these changes are deferred on the balance sheet in Accumulated other comprehensive loss until realized.

Analysis of the Consolidated Balance Sheets

December 31, 2021 vs. December 31, 2020

For a discussion about the changes in Cash and cash equivalents, Short-term borrowings, Current portion of long-term debt and Long-term debt, net of discount and issuance costs, see “Analysis of financial condition, liquidity and capital resources” below.

Accounts Receivable, less allowance for doubtful accounts increased primarily as a result of higher net sales in the period and the timing of customer payments, partially offset by the impact of foreign exchange and rebate credits issued to customers.

Inventories increased primarily as a result of the build-up of certain products for increased demand and new product launches, partially offset by higher sales than anticipated for certain products. See Notes to Consolidated Financial Statements - Note 11. Inventories.

Other current assets increased primarily due to the mark-to-market adjustment of derivative instruments and higher prepaid expenses, partially offset by the timing of income tax payments.

Property, plant and equipment less accumulated depreciation increased primarily as a result of capital spending, partially offset by depreciation expense. See Notes to Consolidated Financial Statements - Note 12. Property, Plant and Equipment

53 |

Table of Contents

The decreases in Operating lease right of use assets and Operating lease liabilities reflect lease amortization and payments, partially offset by assets acquired through new lease obligations. See Notes to Consolidated Financial Statements - Note 10. Leases.

Identifiable intangible assets, less accumulated amortization decreased primarily as a result of amortization expense, the impairment of certain intangible assets and the impact of foreign exchange, partially offset by intangible asset additions from acquisitions. See Notes to Consolidated Financial Statements - Note 13. Goodwill and Other Intangible Assets.

Dividends payable increased as a result of an increase in the dividend rate for the first quarter 2022 dividend, which was declared on December 7, 2021.

Accrued expenses increased primarily as a result of accrued contract rebates, accrued third-party inventory and other accrued expenses.

Accrued compensation and related items increased primarily due to the accrual of 2021 annual incentive bonuses and a higher sales incentive bonus accrual, as well as the reclassification of FICA payroll taxes to be paid in 2022 under the CARES Act from Other noncurrent liabilities, partially offset by the payment of the 2020 annual incentive bonuses.

The net changes in Noncurrent deferred tax assets, Noncurrent deferred tax liabilities, Income taxes payable and Other taxes payable primarily reflect adjustments to the accrual for the income tax provision, the timing of income tax payments, the tax impact of various acquisitions, the impact of the remeasurement of deferred tax assets and liabilities as a result of changes in tax rates.

Other current liabilities and Other noncurrent liabilities decreased primarily due to the mark-to-market adjustment of derivative instruments, the reclassification of FICA payroll taxes to be paid in 2022 under the CARES Act to Accrued compensation and related items and decreases in accrued pension benefits and deferred compensation related to net investment activity.

Operating activities

2021 vs. 2020

Net cash provided by operating activities was $2,213 million in 2021 compared with $2,126 million in 2020. The increase in operating cash flows was primarily attributable to higher cash earnings, partially offset by timing of receipts and payments in the ordinary course of business.

Investing activities

2021 vs. 2020

Net cash used in investing activities was $458 million in 2021 compared with $572 million in 2020. The net cash used in investing activities for 2021 was primarily attributable to capital expenditures, acquisitions and purchase of investments, partially offset by proceeds from cross-currency interest rate swaps. The net cash used in investing activities for 2020 was primarily due to capital expenditures, acquisitions and net payments for cross-currency interest rate swaps, partially offset by proceeds from the sale of assets, including a cash payment received pursuant to an agreement related to the 2016 sale of certain U.S. manufacturing sites.

Financing activities

2021 vs. 2020

Net cash used in financing activities was $1,862 million in 2021 compared with net cash provided by financing activities of $123 million in 2020. The net cash used in financing activities for 2021 was primarily attributable to the purchase of treasury shares, the repayment of the $300 million aggregate principal amount of our 2018 floating rate senior notes due 2021 and the $300 million aggregate principal amount of our 2018 senior notes due 2021, the payment of dividends and taxes paid on withholding shares, partially offset by proceeds in connection with the issuance of common stock under our equity incentive plan. The net cash provided by financing activities for 2020 was primarily attributable to the proceeds received from the issuance of senior notes in May 2020 and net proceeds in connection with the issuance of common stock under our equity incentive plan, partially offset by the payment of dividends and the purchase of treasury shares.

Analysis of financial condition, liquidity and capital resources

While we believe our cash and cash equivalents on hand, our operating cash flows and our existing financing arrangements will be sufficient to support our cash needs for the next twelve months and beyond, this may be subject to the environment in which we operate. Risks to our meeting future funding requirements include global economic conditions described in the following paragraph.

Global financial markets may be impacted by macroeconomic, business and financial volatility. As markets change, we will continue to monitor our liquidity position. While we do not anticipate it, there can be no assurance that a challenging economic environment or an economic downturn will not impact our liquidity or our ability to obtain future financing.

Selected measures of liquidity and capital resources

Certain relevant measures of our liquidity and capital resources follow:

December 31,December 31,
(MILLIONS OF DOLLARS)20212020
Cash and cash equivalents$3,485$3,604
Accounts receivable, net(a)1,1331,013

Long-term debt6,5926,595
Working capital5,1334,441
Ratio of current assets to current liabilities3.86:13.05:1

(a)    Accounts receivable are usually collected over a period of 45 to 75 days. For the years ended December 31, 2021 and 2020, the number of days that accounts receivables were outstanding have remained within this range. We regularly monitor our accounts receivable for collectability, particularly in markets where economic conditions remain uncertain. We believe that our allowance for doubtful accounts is appropriate. Our assessment is based on such factors as past due aging, historical and expected collection patterns, the financial condition of our customers, the robust nature of our credit and collection practices and the economic environment.

For additional information about the sources and uses of our funds, see the Analysis of the Consolidated Balance Sheets and Analysis of the Consolidated Statements of Cash Flows sections of this MD&A.

Credit facility and other lines of credit

In December 2016, we entered into an amended and restated revolving credit agreement with a syndicate of banks providing for a multi-year $1.0 billion senior unsecured revolving credit facility (the credit facility). In December 2018, the maturity for the amended and restated credit facility was extended through December 2023. Subject to certain conditions, we have the right to increase the credit facility to up to $1.5 billion. The credit facility contains a financial covenant requiring us to not exceed a maximum total leverage ratio (the ratio of consolidated net debt as of the end of the period to consolidated Earnings Before Interest, Income Taxes, Depreciation and Amortization (EBITDA) for such period) of 3.50:1. Upon entering into a material acquisition, the maximum total leverage ratio increases to 4.00:1, and extends until the fourth full consecutive fiscal quarter ended immediately following the consummation of a material acquisition.

The credit facility also contains a financial covenant requiring that we maintain a minimum interest coverage ratio (the ratio of EBITDA at the end of the period to interest expense for such period) of 3.50:1. In addition, the credit facility contains other customary covenants.

We were in compliance with all financial covenants as of December 31, 2021 and December 31, 2020. There were no amounts drawn under the credit facility as of December 31, 2021 or December 31, 2020.

We have additional lines of credit and other credit arrangements with a group of banks and other financial intermediaries for general corporate purposes. We maintain cash and cash equivalent balances in excess of our outstanding short-term borrowings. As of December 31, 2021, we had access to $63 million of lines of credit which expire at various times through 2022, and are generally renewed annually. We had no borrowings outstanding related to these facilities as of December 31, 2021 and $4 million borrowings outstanding as of December 31, 2020.

Domestic and international short-term funds

Many of our operations are conducted outside the U.S. The amount of funds held in the U.S. will fluctuate due to the timing of receipts and payments in the ordinary course of business and due to other reasons, such as business development activities. As part of our ongoing liquidity assessments, we regularly monitor the mix of U.S. and international cash flows (both inflows and outflows). Actual repatriation of overseas funds can result in additional U.S and local income taxes, such as U.S. state income taxes, local withholding taxes, and taxes on currency gains and losses. See Notes to Consolidated Financial Statements— Note 8. Tax Matters.

Global economic conditions

Challenging economic conditions in recent years have not had, nor do we anticipate that it will have, a significant impact on our liquidity. Due to our operating cash flows, financial assets, access to capital markets and available lines of credit and revolving credit agreements, we continue to believe that we have the ability to meet our liquidity needs for the foreseeable future. As markets change, we continue to monitor our liquidity position. There can be no assurance that a challenging economic environment or an economic downturn would not impact our ability to obtain financing in the future.

Contractual obligations

In the normal course of business, we enter into contracts and commitments that obligate us to make payments in the future. These obligations include long-term debt, including interest obligations, purchase obligations, operating lease commitments, other liabilities, benefit plan obligations and uncertain tax positions. See Notes to Consolidated Financial Statements—Note 9. Financial Instruments, Note 18. Commitments and Contingencies, Note 10. Leases, Note 6. Restructuring Charges and Other Costs Associated with Acquisitions, Cost-Reduction and Productivity Initiatives, Note 14. Benefit Plans and Note 8.

Debt securities

On August 20, 2021, we redeemed, upon maturity, the $300 million aggregate principal amount of our 2018 floating rate senior notes due 2021 and the $300 million aggregate principal amount of our 2018 senior notes due 2021.

On May 12, 2020, we issued $1.25 billion aggregate principal amount of our senior notes (2020 senior notes), with an original issue discount of $10 million. These notes are comprised of $750 million aggregate principal amount of 2.000% senior notes due 2030 and $500 million aggregate principal amount of 3.000% senior notes due 2050. On October 13, 2020, the net proceeds were used to repay the $500 million aggregate principal amount of our 3.450% 2015 senior notes due 2020 and the remainder is being used for general corporate purposes.

On August 20, 2018, we issued $1.5 billion aggregate principal amount of our senior notes (2018 senior notes), with an original issue discount of $4 million. On September 12, 2017, we issued $1.25 billion aggregate principal amount of our senior notes (2017 senior notes), with an original issue discount of $7 million. On November 13, 2015, we issued $1.25 billion aggregate principal amount of our senior notes (2015 senior notes), with an original issue discount of $2 million. On January 28, 2013, we issued $3.65 billion aggregate principal amount of our senior notes (2013 senior notes) in a private placement, with an original issue discount of $10 million.

The 2013, 2015, 2017, 2018 and 2020 senior notes are governed by an indenture and supplemental indenture (collectively, the indenture) between us and Deutsche Bank Trust Company Americas, as trustee. The indenture contains certain covenants, including limitations on our and certain of our subsidiaries' ability to incur liens or engage in sale lease-back transactions. The indenture also contains restrictions on our ability to consolidate, merge or sell substantially all of our assets. In addition, the indenture contains other customary terms, including certain events of default, upon the occurrence of which, the 2013, 2015, 2017, 2018 and 2020 senior notes may be declared immediately due and payable.

Pursuant to the indenture, we are able to redeem the 2013, 2015, 2017, 2018 and 2020 senior notes of any series, in whole or in part, at any time by paying a “make whole” premium, plus accrued and unpaid interest to, but excluding, the date of redemption. Pursuant to our tax matters agreement with Pfizer, we will not be permitted to redeem the 2013 senior notes due 2023 pursuant to this optional redemption provision, except under limited circumstances. Upon the occurrence of a change of control of us and a downgrade of the 2013, 2015, 2017, 2018 and 2020 senior notes below an investment grade rating by each of Moody's Investors Service, Inc. and Standard & Poor's Ratings Services, we are, in certain circumstances, required to make an offer to repurchase all of the outstanding 2013, 2015, 2017, 2018 and 2020 senior notes at a price equal to 101% of the aggregate principal amount of the 2013, 2015, 2017, 2018 and 2020 senior notes together with accrued and unpaid interest to, but excluding, the date of repurchase.

Credit ratings

Two major corporate debt-rating organizations, Moody's and S&P, assign ratings to our short-term and long-term debt. A security rating is not a recommendation to buy, sell or hold securities and the rating is subject to revision or withdrawal at any time by the rating organization. Each rating should be evaluated independently of any other rating.

Pension obligations

Our employees ceased to participate in the Pfizer U.S. qualified defined benefit and U.S. retiree medical plans effective December 31, 2012, and liabilities associated with our employees under these plans were retained by Pfizer. As part of the separation from Pfizer, Pfizer continued to credit certain employees' service with Zoetis generally through December 31, 2017 (or termination of employment from Zoetis, if earlier), for certain early retirement benefits with respect to Pfizer's U.S. defined benefit pension and retiree medical plans. In connection with the employee matters agreement, Zoetis is responsible for payment of three-fifths of the total cost of the service credit continuation (approximately $38 million) for these plans. The amount of the service cost continuation payment to be paid by Zoetis to Pfizer was determined and fixed based on an actuarial assessment of the value of the grow-in benefits and will be paid in equal installments over a period of 10 years. As of December 31, 2021, the remaining payments due to Pfizer (approximately $4 million in the aggregate) are to be paid over the next year.

As part of the separation from Pfizer, Pfizer transferred to us the net pension obligations associated with certain international defined benefit plans. We expect to contribute a total of approximately $5 million to these plans in 2022.

As of December 31, 2021, the supplemental savings plan liability was approximately $51 million.

For additional information, see Notes to Consolidated Financial Statements— Note 14. Benefit Plans.

Share repurchase program

In December 2018, the company's Board of Directors authorized a $2.0 billion share repurchase program. As of December 31, 2021, there was approximately $681 million remaining under this authorization. Purchases of Zoetis shares may be made at the discretion of management, depending on market conditions and business needs. Share repurchases may be executed through various means, including open market or privately negotiated transactions. The company temporarily suspended share repurchases beginning in the second quarter of 2020. In January 2021, the company resumed share repurchases under its share repurchase program. During 2021, approximately 4.0 million shares were repurchased.

In December 2021, the company's Board of Directors authorized a $3.5 billion share repurchase program.

Off-balance sheet arrangements

In the ordinary course of business and in connection with the sale of assets and businesses, we may indemnify our counterparties against certain liabilities that may arise in connection with a transaction or that are related to activities prior to a transaction. These indemnifications typically pertain to environmental, tax, employee and/or product-related matters, and patent-infringement claims. If the indemnified party were to make a successful claim pursuant to the terms of the indemnification, we would be required to reimburse the loss. These indemnifications are generally subject to threshold amounts, specified claim periods and other restrictions and limitations. Historically, we have not paid significant amounts under these provisions and, as of December 31, 2021 and December 31, 2020, recorded amounts for the estimated fair value of these indemnifications are not significant.

New accounting standards

Significant Accounting Policies in the Notes to Consolidated Financial Statements for discussion of recent accounting pronouncements, including the respective dates of adoption or expected adoption and effects or expected effects on our consolidated financial position, results of operations and cash flows.

Such risks and uncertainties may be amplified by the COVID-19 pandemic and its impact on the global economy and our business. You should not put undue reliance on forward-looking statements. Forward-looking statements speak only as of the date on which they are made. We undertake no obligation to publicly update forward-looking statements, whether as a result of new information, future events or otherwise, except as required by law or by the rules and regulations of the SEC. You are advised, however, to consult any further disclosures we make on related subjects in our Form 10-Q and 8-K reports and our other filings with the SEC. You should understand that it is not possible to predict or identify all such factors. Consequently, you should not consider the above to be a complete discussion of all potential risks or uncertainties.
