ZOETIS INC. AND SUBSIDIARIES

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(UNAUDITED)

1. Organization

Zoetis Inc. (including its subsidiaries, collectively, Zoetis, the company, we, us or our) 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 technology. We organize and operate our business in two geographic regions: the United States (U.S.) and International.

We directly market our products in approximately 45 countries across North America, Europe, Africa, Asia, Australia and South America. Our products are sold in more than 100 countries, including developed markets and emerging markets. We have a diversified business, commercializing products across eight core species: dogs, cats and horses (collectively, companion animals) and cattle, swine, poultry, fish and sheep (collectively, livestock); and within seven major product categories: parasiticides, vaccines, dermatology, other pharmaceutical products, anti-infectives, animal health diagnostics and medicated feed additives.

2. Basis of Presentation

The accompanying unaudited condensed consolidated financial statements were prepared following the requirements of the Securities and Exchange Commission (SEC) for interim reporting. As permitted under those rules, certain footnotes or other financial information that are normally required by accounting principles generally accepted in the United States of America (U.S. GAAP) can be condensed or omitted. Balance sheet amounts and operating results for subsidiaries operating outside the U.S. are as of and for the three and six months ended May 31, 2023 and May 31, 2022.

Revenue, expenses, assets and liabilities can vary during each quarter of the year. Therefore, the results and trends in these interim financial statements may not be representative of those for the full year.

We are responsible for the unaudited condensed consolidated financial statements included in this Form 10-Q. The condensed consolidated financial statements include all normal and recurring adjustments that are considered necessary for the fair presentation of our financial position and operating results. The information included in this interim report should be read in conjunction with the financial statements and accompanying notes included in our 2022 Annual Report on Form 10-K.

3. Accounting Standards

Recently Adopted Accounting Standards

In March 2020, the FASB issued ASU No. 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting. In January 2021 and December 2022, it issued subsequent amendments to the initial guidance: ASU No. 2021-01 and ASU No. 2022-06, Reference Rate Reform (Topic 848). The new guidance provides temporary optional expedients and exceptions for applying GAAP to contracts, hedging relationships, and other transactions that reference the London Interbank Offered Rate (LIBOR) or another reference rate expected to be discontinued because of reference rate reform. Adoption of the guidance is optional and effective as of March 12, 2020, but only available through December 31, 2024. During the first quarter of 2023, we adopted the guidance by executing amendments to our affected contracts that referenced LIBOR. The adoption did not have a material impact on our condensed consolidated financial statements or related disclosures.

4. Revenue

A. Revenue from Product Sales

We offer a diversified portfolio of products which allows us to capitalize on local and regional customer needs. 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. Many of our top-selling product lines are distributed across both of our operating segments, leveraging our research and development (R&D) operations and manufacturing and supply chain network.

Over the course of our history, we have focused on developing a diverse portfolio of animal health products, including medicines, vaccines and diagnostics, complemented by biodevices, genetic tests and a range of services. We refer to all different brands of a particular product, or its dosage forms for all species, as a product line. We have approximately 300 comprehensive product lines, including products for both companion animals and livestock within each of our major product categories.

Our major product categories are:

•parasiticides: products that prevent or eliminate external and internal parasites such as fleas, ticks and worms;

•vaccines: biological preparations that help prevent diseases of the respiratory, gastrointestinal and reproductive tracts or induce a specific immune response;

•dermatology products: products that relieve itch associated with allergic conditions and atopic dermatitis;

•other pharmaceutical products: pain and sedation, antiemetic, reproductive, and oncology products;

•anti-infectives: products that prevent, kill or slow the growth of bacteria, fungi or protozoa;

•animal health diagnostics: testing and analysis of blood, urine and other animal samples and related products and services, including point-of-care diagnostic products, instruments and reagents, rapid immunoassay tests, reference laboratory kits and services and blood glucose monitors; and

7 |

•medicated feed additives: products added to animal feed that provide medicines to livestock.

Our remaining revenue is derived from other non-pharmaceutical product categories, such as nutritionals, as well as products and services in biodevices, genetic tests and precision animal health.

Our companion animal products help extend and improve the quality of life for pets; increase convenience and compliance for pet owners; and help veterinarians improve the quality of their care and the efficiency of their businesses. Growth in the companion animal medicines, vaccines and diagnostics sector is driven by economic development, related increases in disposable income and increases in pet ownership and spending on pet care. Companion animals are also living longer, deepening the human-animal bond, receiving increased medical treatment and benefiting from advances in animal health medicine, vaccines and diagnostics.

Our livestock products primarily help prevent or treat diseases and conditions to allow veterinarians and producers to care for their animals and to enable the cost-effective production of safe, high-quality animal protein. Human population growth and increasing standards of living are important long-term growth drivers for our livestock products in three major ways. First, population growth and increasing standards of living drive demand for improved nutrition, particularly through increased consumption of animal protein. Second, population growth leads to greater natural resource constraints driving a need for enhanced productivity. Finally, as standards of living improve and the global food chain faces increased scrutiny, there is more focus on food quality, safety and reliability of supply.

The following tables present our revenue disaggregated by geographic area, species and major product category:

B. Revenue from Contracts with Customers

Contract liabilities reflected within Other current liabilities as of December 31, 2022 and 2021, and subsequently recognized as revenue during the first six months of 2023 and 2022 were $3 million and $2 million, respectively. Contract liabilities as of June 30, 2023 and December 31, 2022 were $15 million and $14 million, respectively.

Estimated future revenue expected to be generated from long-term contracts with unsatisfied performance obligations as of June 30, 2023 is not material.

5. Acquisitions and Divestitures

A. Acquisitions

In 2022, we completed the acquisition of Basepaws, a privately held petcare genetics company based in the U.S., which provides pet owners with genetic tests, analytics and early health risk assessments that can help manage the health, wellness and quality of care for their pets. We also completed the acquisition of NewMetrica, a privately held company based in Scotland, that provides scientifically-developed instruments to measure quality of life in companion animals. These transactions did not have a material impact on our condensed consolidated financial statements.

During 2021, we entered into an agreement to acquire Jurox, a privately held animal health company based in Australia, which develops, manufactures and markets a wide range of veterinary medicines for treating companion animals and livestock. On September 30, 2022, after satisfying all customary closing conditions, including clearance from the Australian Competition and Consumer Commission, we completed the acquisition of Jurox. We acquired 100% of the outstanding shares for an aggregate cash purchase price of $226 million, which was adjusted to $240 million for cash and working capital and other adjustments as of the closing date. Net cash consideration transferred to the seller was $215 million during 2022 and $5 million for the six months ended June 30, 2023. The transaction was accounted for as a business combination, with the assets acquired and liabilities assumed measured at their respective acquisition date fair values. The table below presents the preliminary fair values allocated to the assets and liabilities of Jurox as of the acquisition date:

(MILLIONS OF DOLLARS)	Amounts
Cash and cash equivalents	$	20
Accounts receivable	8
Inventories(a)	21
Other current assets	1
Property, plant and equipment(b)	25
Identifiable intangible assets(c)	135
Other noncurrent assets	1
Accounts payable	2
Other current liabilities	12
Total net assets acquired	197
Goodwill(d)	43
Total consideration	$	240

(a)        Acquired inventory is comprised of finished goods, work in process and raw materials. The fair value of finished goods was determined based on net realizable value adjusted for the costs of the selling effort, a reasonable profit allowance for the selling effort, and estimated holding costs. The fair value of work in process was determined based on net realizable value adjusted for costs to complete the manufacturing process, costs of the selling effort, a reasonable profit allowance for the remaining manufacturing and selling effort, and an estimate of holding costs. The fair value of raw materials was determined to approximate book value.

(b)    Property, plant and equipment is comprised of buildings, machinery and equipment, land, construction in progress and furniture and fixtures. The fair value was primarily determined using a reproduction/replacement cost approach which measures the value of an asset by estimating the cost to acquire or construct comparable assets adjusted for age and condition of the asset.

(c)    Identifiable intangible assets consist of developed technology rights. The fair value of identifiable intangible assets was determined using the income approach, which includes a forecast of expected future cash flows. For additional information regarding identifiable intangible assets, see Note 11. Goodwill and Other Intangible Assets.

(d)        Goodwill represents the excess of consideration transferred over the fair values of the assets acquired and liabilities assumed. It is allocated to our International segment and is primarily attributable to cost and revenue synergies including market share capture, elimination of cost redundancies and gain of cost efficiencies, and intangible assets such as assembled workforce which are not separately recognizable. The primary strategic purpose of the acquisition was to enhance the company’s existing product portfolio.

All amounts recorded are subject to final valuation. Any adjustments to our preliminary purchase price allocation identified during the measurement period, which will not exceed one year from the acquisition date, will be accounted for prospectively.

B. Divestitures

During the second quarter of 2023, we received net cash proceeds of $93 million ($99 million sales proceeds, net of cash sold of $6 million) for the sale of a majority interest in our pet insurance business, Pumpkin Insurance Services. For the three months ended June 30, 2023, we recorded a net pre-tax gain of $101 million within Other (income)/deductions—net, which includes $24 million related to the remeasurement of our retained noncontrolling investment to fair value.

6. Restructuring Charges and Other Costs Associated with Acquisitions, Cost-Reduction and Productivity
Initiatives

In connection with our cost-reduction/productivity initiatives, we typically incur costs and charges associated with site closings and other facility rationalization actions, workforce reductions and the expansion of shared services, including the development of global systems. In connection with our acquisition activity, we typically incur costs and charges associated with executing the transactions, integrating the acquired operations, which may include expenditures for consulting and the integration of systems and processes, product transfers and restructuring the consolidated company, which may include charges related to employees, assets and activities that will not continue in the consolidated company. All operating functions can be impacted by these actions, including sales and marketing, manufacturing and R&D, as well as functions such as business technology, shared services and corporate operations.

(c)    Relates to the gain on sale of a majority interest in our pet insurance business. For additional information, see Note 5. Acquisitions and Divestitures.

(d)    Primarily driven by costs related to hedging and exposures to certain emerging and developed market currencies.

8. Income Taxes

A. Taxes on Income

Our effective tax rate was 23.2% and 21.0% for the three months ended June 30, 2023 and 2022, respectively, and 22.2% and 19.6% for the six months ended June 30, 2023 and 2022, respectively. The higher effective tax rates for the three and six months ended June 30, 2023, compared with the three and six months ended June 30, 2022, were attributable to a higher net discrete tax expense mainly related to changes to prior years' tax positions and a less favorable jurisdictional mix of earnings (which includes the impact of the location of earnings and repatriation costs), partially offset by a higher benefit in the U.S. related to foreign-derived intangible income. 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.

In 2022, the company implemented an initiative to maximize its cash position in the U.S. This initiative resulted in a tax benefit in the U.S. in connection with a prepayment from a related foreign entity in Belgium which qualifies as foreign-derived intangible income; however, this income tax benefit was deferred to 2023 and 2024. A portion of this benefit was recognized during the three and six months ended June 30, 2023.

11 |

B. Deferred Taxes

As of June 30, 2023, the total net deferred income tax asset of $71 million is included in Noncurrent deferred tax assets ($192 million) and Noncurrent deferred tax liabilities ($121 million).

As of December 31, 2022, the total net deferred income tax asset of $31 million is included in Noncurrent deferred tax assets ($173 million) and Noncurrent deferred tax liabilities ($142 million).

C. Tax Contingencies

As of June 30, 2023, the net tax liabilities associated with uncertain tax positions of $217 million (exclusive of interest and penalties related to uncertain tax positions of $27 million) are included in Noncurrent deferred tax assets and Other noncurrent assets ($1 million) and Other taxes payable ($216 million).

As of December 31, 2022, the net tax liabilities associated with uncertain tax positions of $194 million (exclusive of interest and penalties related to uncertain tax positions of $19 million) are included in Noncurrent deferred tax assets and Other noncurrent assets ($2 million) and Other taxes payable ($192 million).

The increase in net tax liabilities associated with uncertain tax positions, as well as the increase in interest and penalties, is mainly attributable to a net discrete tax expense related to changes in prior years' uncertain tax positions recognized in the three and six months ended June 30, 2023.

Our tax liabilities for uncertain tax positions relate primarily to issues common among multinational corporations. Any settlements or statute of limitations expirations could result in a significant decrease in our uncertain tax positions. Substantially all of these unrecognized tax benefits, if recognized, would impact our effective income tax rate. We do not expect that within the next twelve months any of our uncertain tax positions could significantly decrease as a result of settlements with taxing authorities or the expiration of the statutes of limitations. Our assessments are based on estimates and assumptions that have been deemed reasonable by management, but our estimates of uncertain tax positions and potential tax benefits may not be representative of actual outcomes, and any variation from such estimates could materially affect our financial statements in the period of settlement or when the statutes of limitations expire, as we treat these events as discrete items in the period of resolution. Finalizing audits with the relevant taxing authorities can include formal administrative and legal proceedings, and, as a result, it is difficult to estimate the timing and range of possible changes related to our uncertain tax positions, and such changes could be significant.

9. Financial Instruments

A. Debt

Credit Facilities

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 2016. 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. In addition, the credit facility contains other customary covenants.

We were in compliance with all financial covenants as of June 30, 2023 and December 31, 2022. There were no amounts drawn under the credit facility as of June 30, 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 June 30, 2023, we had access to $52 million of lines of credit which expire at various times and are generally renewed annually. There was $2 million of borrowings outstanding related to these facilities as of June 30, 2023 and December 31, 2022.

Commercial Paper Program

In February 2013, we entered into a commercial paper program with a capacity of up to $1.0 billion. As of June 30, 2023 and December 31, 2022, there was no commercial paper outstanding under this program.

Senior Notes and Other Long-Term Debt

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-leaseback 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

12 |

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.

The components of our long-term debt are as follows:

	June 30,		December 31,
(MILLIONS OF DOLLARS)	2023		2022

The fair value of our long-term debt was $6,153 million and $6,108 million as of June 30, 2023 and December 31, 2022, respectively, and has been determined using a third-party matrix-pricing model that uses significant inputs derived from, or corroborated by, observable market data and Zoetis’ credit rating (Level 2 inputs).

The principal amount of long-term debt outstanding, as of June 30, 2023, matures in the following years:

Interest Expense

Interest expense, net of capitalized interest, was $58 million and $121 million for the three and six months ended June 30, 2023, respectively, and $53 million and $106 million for the three and six months ended June 30, 2022, respectively. Capitalized interest expense was $6 million and $12 million for the three and six months ended June 30, 2023, respectively, and $6 million and $11 million for the three and six months ended June 30, 2022, respectively.

B. Derivative Financial Instruments

Foreign Exchange Risk

A significant portion of our revenue, earnings and net investment in foreign affiliates is exposed to changes in foreign exchange rates. 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. Depending on market conditions, foreign exchange risk is also managed through the use of various derivative financial instruments. These derivative financial instruments serve to manage the exposure of our net investment in certain foreign operations to changes in foreign exchange rates and protect net income against the impact of translation into U.S. dollars of certain foreign exchange-denominated transactions.

All derivative financial instruments used to manage foreign currency risk are measured at fair value and are reported as assets or liabilities on the Condensed Consolidated Balance Sheets. The derivative financial instruments primarily offset exposures in the British pound, Canadian dollar, Chinese yuan, euro, Japanese yen and Norwegian krone. Changes in fair value are reported in earnings or in Accumulated other comprehensive income/(loss), depending on the nature and purpose of the financial instrument, as follows:

•For foreign currency forward-exchange contracts not designated as hedging instruments, we recognize the gains and losses that are used to offset the same foreign currency assets or liabilities immediately into earnings along with the earnings impact of the items they generally offset. These contracts essentially take the opposite currency position of that reflected in the month-end balance sheet to counterbalance the effect of any currency movement. The vast majority of the foreign currency forward-exchange contracts mature within 60 days and all mature within three years.

•For foreign exchange derivative instruments that are designated as hedging instruments against our net investment in foreign operations, changes in the fair value are recorded as a component of cumulative translation adjustment within Accumulated other comprehensive income/(loss) and reclassified into earnings when the foreign investment is sold or substantially liquidated. These instruments include cross-currency interest rate swaps and foreign currency forward-exchange contracts. Gains and losses excluded from the assessment of hedge effectiveness are recognized in earnings (Interest expense, net of capitalized interest). The cash flows from these contracts are reflected within the investing section of our Condensed Consolidated Statements of Cash Flows. These contracts have varying maturities of

13 |

up to two years.

Interest Rate Risk

The company may use interest rate swap contracts on certain investing and borrowing transactions to manage its net exposure to interest rates and to reduce its overall cost of borrowing.

•In anticipation of issuing fixed-rate debt, we may use forward-starting interest rate swaps that are designated as cash flow hedges to hedge against changes in interest rates that could impact expected future issuances of debt. Unrealized gains or losses on the forward-starting interest rate swaps are reported in Accumulated other comprehensive loss and are recognized in earnings over the life of the future fixed rate notes. When the company discontinues hedge accounting because it is no longer probable that an anticipated transaction will occur within the originally expected period of execution, or within an additional two-month period thereafter, changes to fair value accumulated in other comprehensive income are recognized immediately in earnings.

•During the period from 2019 to 2022, we entered into forward-starting interest rate swaps with an aggregate notional value of $650 million. We designated these swaps as cash flow hedges against interest rate exposure related principally to the issuance of fixed-rate debt to refinance our 3.250% 2013 senior notes due 2023. Upon issuance of our 2022 senior notes, we terminated these contracts and received $114 million in cash from the counterparties for settlement, included in Net cash provided by operating activities in the Consolidated Statements of Cash Flows. The settlement amount, which represented the fair value of the contracts at the time of termination, was recorded in Accumulated other comprehensive loss, and will be amortized into income (offset to Interest expense, net of capitalized interest) over the life of the 5.600% 2022 senior notes due 2032.

•As of June 30, 2023, we had outstanding forward-starting interest rate swaps, having an effective date and mandatory termination date in March 2026, to hedge against interest rate exposure related principally to the anticipated future issuance of fixed-rate debt to be used primarily to refinance our 4.500% 2015 senior notes due 2025.

•We may use fixed-to-floating interest rate swaps that are designated as fair value hedges to hedge against changes in the fair value of certain fixed-rate debt attributable to changes in the benchmark Secured Overnight Financing Rate (SOFR). These derivative instruments effectively convert a portion of the company’s long-term debt from fixed-rate to floating-rate debt based on the daily SOFR rate plus a spread. Gains or losses on the fixed-to-floating interest rate swaps due to changes in SOFR are recorded in Interest expense, net of capitalized interest. Changes in the fair value of the fixed-to-floating interest rate swaps are offset by changes in the fair value of the underlying fixed-rate debt. As of June 30, 2023, we had outstanding fixed-to-floating interest rate swaps that correspond to a portion of the 3.900% 2018 senior notes due 2028 and the 2.000% senior notes due 2030. The amounts recorded during the three and six months ended June 30, 2023 for changes in the fair value of these hedges are not material to our condensed consolidated financial statements.

During the first quarter of 2023, we executed amendments to certain of our interest rate swap contracts, which changed the floating rate index from LIBOR to SOFR. These amendments did not have a material impact on our condensed consolidated financial statements.

The company’s derivative transactions are subject to master netting agreements that mitigate credit risk by permitting net settlement of transactions with the same counterparty. The company also has collateral security agreements with certain of its counterparties. Under these collateral security agreements either party is required to post cash collateral when the net fair value of derivative instruments covered by the collateral agreement exceeds contractually established thresholds. At June 30, 2023, there was $2 million of collateral received and $37 million of collateral posted related to derivative instruments recorded in Other current liabilities and Other current assets, respectively. At December 31, 2022, there was $8 million of collateral received and $21 million of collateral posted related to derivative instruments recorded in Other current liabilities and Other current assets, respectively.

We use a market approach in valuing financial instruments on a recurring basis. Our derivative financial instruments are measured at fair value on a recurring basis using Level 2 inputs in the calculation of fair value.

The amounts of net losses on derivative instruments not designated as hedging instruments, recorded in Other (income)/deductions—net, are as follows:

C. Amortization

Amortization expense related to finite-lived acquired intangible assets that contribute to our ability to sell, manufacture, research, market and distribute products, compounds and intellectual property is included in Amortization of intangible assets as it benefits multiple business functions. Amortization expense related to finite-lived acquired intangible assets that are associated with a single function is included in Cost of sales, Selling, general and administrative expenses or Research and development expenses, as appropriate. Total amortization expense for finite-lived intangible assets was $48 million and $95 million for the three and six months ended June 30, 2023, respectively, and $47 million and $99 million for the three and six months ended June 30, 2022, respectively.

12. Share-based Payments

The Zoetis 2013 Equity and Incentive Plan (Equity Plan) provides long-term incentives to our employees and non-employee directors. The principal types of share-based awards available under the Equity Plan may include, but are not limited to, stock options, restricted stock and restricted stock units (RSUs), deferred stock units (DSUs), performance-vesting restricted stock units (PSUs) and other equity-based or cash-based awards.

16 |

The components of share-based compensation expense are as follows:

	Three Months Ended				Six Months Ended
	June 30,				June 30,
(MILLIONS OF DOLLARS)	2023		2022		2023		2022
Stock options / stock appreciation rights	$	2	$	3	$	3	$	5
RSUs / DSUs	10		8		17		17
PSUs	5		4		6		9
Share-based compensation expense—total(a)	$	17	$	15	$	26	$	31

(a) For the three and six months ended June 30, 2023 and 2022, we capitalized less than $1 million of share-based compensation expense to inventory.

During the six months ended June 30, 2023, the company granted 271,150 stock options with a weighted-average exercise price of $162.12 per stock option and a weighted-average fair value of $43.56 per stock option. The fair-value based method for valuing each Zoetis stock option grant on the grant date uses the Black-Scholes-Merton option-pricing model, which incorporates a number of valuation assumptions. The weighted-average fair value was estimated based on the following assumptions: risk-free interest rate of 3.84%; expected dividend yield of 0.92%; expected stock price volatility of 28.63%; and expected term of 4.2 years. In general, stock options granted prior to 2023 vest after three years of continuous service, while stock options granted in 2023 are subject to graded vesting over three years. The values determined through this fair-value based method generally are amortized on a straight-line basis over the vesting term into Cost of sales, Selling, general and administrative expenses, or Research and development expenses, as appropriate.

During the six months ended June 30, 2023, the company granted 267,535 RSUs, with a weighted-average grant date fair value of $162.18 per RSU. RSUs are accounted for using a fair-value-based method that utilizes the closing price of Zoetis common stock on the date of grant. In general, RSUs granted prior to 2023 vest after three years of continuous service from the grant date while RSUs granted in 2023 are subject to graded vesting over three years. The values generally are amortized on a straight-line basis over the vesting term into Cost of sales, Selling, general and administrative expenses, or Research and development expenses, as appropriate.

During the six months ended June 30, 2023, the company granted 99,626 PSUs with a weighted-average grant date fair value of $238.24 per PSU. PSUs are accounted for using a Monte Carlo simulation model. The units underlying the PSUs will be earned and vested over a three-year performance period, based upon the total shareholder return of the company in comparison to the total shareholder return of the companies comprising the S&P 500 stock market index at the start of the performance period, excluding companies that during the performance period are acquired or no longer publicly traded (Relative TSR). The weighted-average fair value was estimated based on volatility assumptions of Zoetis common stock and an average of the S&P 500 companies, which were 31.8% and 40.9%, respectively. Depending on the company’s Relative TSR performance at the end of the performance period, the recipient may earn from 0% to 200% of the target number of units. Vested units are settled in shares of the company’s common stock. PSU values are amortized on a straight-line basis over the vesting term into Cost of sales, Selling, general and administrative expenses, or Research and development expenses, as appropriate.

13. Stockholders' Equity

Zoetis is authorized to issue 6 billion shares of common stock and 1 billion shares of preferred stock.

In December 2021, our Board of Directors authorized a $3.5 billion share repurchase program. As of June 30, 2023, there was $2.0 billion remaining under this authorization. Purchases of Zoetis shares may be made at the discretion of management, depending on market conditions and business needs.

14. Earnings per Share

The following table presents the calculation of basic and diluted earnings per share:

	Three Months Ended				Six Months Ended
(MILLIONS OF DOLLARS AND SHARES, EXCEPT PER SHARE DATA)	June 30,				June 30,
	2023		2022		2023		2022

Net income before allocation to noncontrolling interests	$	670	$	529	$	1,221	$	1,123
Less: Net loss attributable to noncontrolling interests	(1)		—		(2)		(1)
Net income attributable to Zoetis Inc.	$	671	$	529	$	1,223	$	1,124
Denominator
Weighted-average common shares outstanding	461.9		470.0		462.7		471.1
Common stock equivalents: stock options, RSUs, PSUs and DSUs	1.0		1.5		1.1		1.7
Weighted-average common and potential dilutive shares outstanding	462.9		471.5		463.8		472.8
Earnings per share attributable to Zoetis Inc. stockholders—basic	$	1.45	$	1.13	$	2.64	$	2.39
Earnings per share attributable to Zoetis Inc. stockholders—diluted	$	1.45	$	1.12	$	2.64	$	2.38

The number of stock options outstanding under the company's Equity Plan that were excluded from the computation of diluted earnings per share, as the effect would have been antidilutive, were not material for the three and six months ended June 30, 2023 and 2022.

15. Commitments and Contingencies

We and certain of our subsidiaries are subject to numerous contingencies arising in the ordinary course of business. For a discussion of our tax contingencies, see Note 8. Income Taxes.

A. Legal Proceedings

Our non-tax contingencies include, among others, the following:

•    Product liability and other product-related litigation, which can include injury, consumer, off-label promotion, antitrust and breach of contract claims.

•    Commercial and other matters, which can include product-pricing claims and environmental claims and proceedings.

•    Patent litigation, which typically involves challenges to the coverage and/or validity of our patents or those of third parties on various products or processes.

•    Government investigations, which can involve regulation by national, state and local government agencies in the U.S. and in other countries.

Certain of these contingencies could result in losses, including damages, fines and/or civil penalties, and/or criminal charges, which could be substantial.

We believe that we have strong defenses in these types of matters, but litigation is inherently unpredictable and excessive verdicts do occur. We do not believe that any of these matters will have a material adverse effect on our financial position. However, we could incur judgments, enter into settlements or revise our expectations regarding the outcome of certain matters, and such developments could have a material adverse effect on our results of operations or cash flows in the period in which the amounts are paid.

We have accrued for losses that are both probable and reasonably estimable. Substantially all of these contingencies are subject to significant uncertainties and, therefore, determining the likelihood of a loss and/or the measurement of any loss can be complex. Consequently, we are unable to estimate the range of reasonably possible loss in excess of amounts accrued. Our assessments are based on estimates and assumptions that have been deemed reasonable by management, but the assessment process relies on estimates and assumptions that may prove to be incomplete or inaccurate, and unanticipated events and circumstances may occur that might cause us to change those estimates and assumptions.

Amounts recorded for legal and environmental contingencies can result from a complex series of judgments about future events and uncertainties and can rely on estimates and assumptions.

The principal matters to which we are a party are discussed below. In determining whether a pending matter is significant for financial reporting and disclosure purposes, we consider both quantitative and qualitative factors in order to assess materiality, such as, among other things, the amount of damages and the nature of any other relief sought in the proceeding, if such damages and other relief are specified; our view of the merits of the claims and of the strength of our defenses; whether the action purports to be a class action and our view of the likelihood that a class will be certified by the court; the jurisdiction in which the proceeding is pending; any experience that we or, to our knowledge, other companies have had in similar proceedings; whether disclosure of the action would be important to a reader of our financial statements, including whether disclosure might change a reader’s judgment about our financial statements in light of all of the information about the company that is available to the reader; the potential impact of the proceeding on our reputation; and the extent of public interest in the matter. In addition, with respect to patent matters, we consider, among other things, the financial significance of the product protected by the patent.

Ulianopolis, Brazil

In February 2012, the Municipality of Ulianopolis (State of Para, Brazil) filed a complaint against Fort Dodge Saúde Animal Ltda. (FDSAL), a Zoetis entity, and five other large companies alleging that waste sent to a local waste incineration facility for destruction, but that was not ultimately destroyed as the facility lost its operating permit, caused environmental impacts requiring cleanup.

18 |

The Municipality is seeking recovery of cleanup costs purportedly related to FDSAL's share of all waste accumulated at the incineration facility awaiting destruction, and compensatory damages to be allocated among the six defendants. We believe we have strong arguments against the claim, including defense strategies against any claim of joint and several liability.

At the request of the Municipal prosecutor, in April 2012, the lawsuit was suspended for one year. Since that time, the prosecutor has initiated investigations into the Municipality's actions in the matter as well as the efforts undertaken by the six defendants to remove and dispose of their individual waste from the incineration facility. On October 3, 2014, the Municipal prosecutor announced that the investigation remained ongoing and outlined the terms of a proposed Term of Reference (a document that establishes the minimum elements to be addressed in the preparation of an Environmental Impact Assessment), under which the companies would be liable to withdraw the waste and remediate the area.

On March 5, 2015, we presented our response to the prosecutor’s proposed Term of Reference, arguing that the proposed terms were overly general in nature and expressing our interest in discussing alternatives to address the matter. The prosecutor agreed to consider our request to engage a technical consultant to conduct an environmental diagnostic of the contaminated area. On May 29, 2015, we, in conjunction with the other defendant companies, submitted a draft cooperation agreement to the prosecutor, which outlined the proposed terms and conditions for the engagement of a technical consultant to conduct the environmental diagnostic. On August 19, 2016, the parties and the prosecutor agreed to engage the services of a third-party consultant to conduct a limited environmental assessment of the site. The site assessment was conducted during June 2017, and a written report summarizing the results of the assessment was provided to the parties and the prosecutor in November 2017. The report noted that waste is still present on the site and that further (Phase II) environmental assessments are needed before a plan to manage that remaining waste can be prepared. On April 1, 2019, the defendants met with the Prosecutor to discuss the conclusions set forth in the written report. Following that discussion, on April 10, 2019, the Prosecutor issued a procedural order requesting that the defendants prepare and submit a technical proposal outlining the steps needed to conduct the additional Phase II environmental assessments. The defendants presented the technical proposal to the Prosecutor on October 21, 2019. On March 3, 2020, the Prosecutor notified the defendants that he submitted the proposal to the Ministry of the Environment for its review and consideration by the Prosecutor. On July 15, 2020, the Prosecutor recommended certain amendments to the proposal for the Phase II testing. On September 28, 2020, the parties and the Prosecutor agreed to the final terms and conditions concerning the cooperation agreement with respect to the Phase II testing. Due to the ongoing issues presented by the coronavirus (COVID-19) pandemic, the parties have been unable to secure a start date for the Phase II testing and have no timeline at this point when testing will begin.

Belgium Excess Profit Tax Regime

On February 14, 2019, the General Court of the European Union (General Court) annulled the January 11, 2016 decision of the European Commission (EC) that selective tax advantages granted by Belgium under its "excess profit" tax scheme constitute illegal state aid. As a result of the 2016 decision, the company recorded a net tax charge of approximately $35 million in the first half of 2016. On May 8, 2019, the EC filed an appeal to the decision of the General Court. On September 16, 2019, the EC opened separate in-depth investigations to assess whether Belgium excess profit rulings granted to 39 multinational companies, including Zoetis, constituted state aid for those companies. On September 16, 2021, the European Court of Justice upheld the EC’s decision that the Belgium excess profit ruling system is considered an aid scheme and referred the case back to the General Court to rule on open questions. On May 24, 2022, the General Court resumed all proceedings involved with the Excess Profit Rulings cases, including Zoetis. On June 23, 2022, as requested by the General Court, the company provided observations in relations to (i) the impact of the Court of Justice’s decision that the Belgium excess profit ruling system is considered an aid scheme and (ii) the impact of recent case laws by the General Court with regards to the existence of a selective advantage. On December 16, 2022, the company submitted observations on the conclusions drawn from the November 8, 2022 Fiat Chrysler Finance Europe and Ireland v Commission judgement, as requested by the General Court. A hearing by the General Court took place on February 15, 2023 and we are now awaiting a decision on our plea. The company has not reflected any potential benefits in its condensed consolidated financial statements as of June 30, 2023 as a result of the 2019 annulment. We will continue to monitor the developments of the appeal and its ultimate resolution.

B. Guarantees and Indemnifications

In the ordinary course of business and in connection with the sale of assets and businesses, we indemnify our counterparties against certain liabilities that may arise in connection with the transaction or related to activities prior to the 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 June 30, 2023, recorded amounts for the estimated fair value of these indemnifications were not material.

16. Segment Information

Operating Segments

We manage our operations through two geographic operating segments: the U.S. and International. Each operating segment has responsibility for its commercial activities. Within each of these operating segments, we offer a diversified product portfolio, including parasiticides, vaccines, dermatology, other pharmaceutical products, anti-infectives, animal health diagnostics and medicated feed additives, for both companion animal and livestock customers. Our chief operating decision maker uses the revenue and earnings of the two operating segments, among other factors, for performance evaluation and resource allocation.

Other Costs and Business Activities

Certain costs are not allocated to our operating segment results, such as costs associated with the following:

•    Other business activities, includes our Client Supply Services (CSS) 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 commercial segment.

19 |

•    Corporate, includes enabling functions such as information technology, facilities, legal, finance, human resources, business development, certain diagnostic costs and communications, among others. These costs also include certain compensation costs, certain procurement costs and other miscellaneous operating expenses not charged to our operating segments, as well as interest income and expense.

•Certain transactions and events such as (i) Purchase accounting adjustments, where we incur expenses associated with the amortization of fair value adjustments to inventory, intangible assets and property, plant and equipment; (ii) Acquisition-related activities, where we incur costs associated with acquiring and integrating newly acquired businesses, such as transaction costs and integration costs; and (iii) Certain significant items, which comprise substantive, unusual items that, either as a result of their nature or size, would not be expected to occur as part of our normal business on a regular basis, such as restructuring charges and implementation costs associated with our cost-reduction/productivity initiatives that are not associated with an acquisition, certain asset impairment charges, certain legal and commercial settlements and the impact of divestiture-related gains and losses.

•Other unallocated 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.

Segment Assets

We manage our assets on a total company basis, not by operating segment. Therefore, our chief operating decision maker does not regularly review any asset information by operating segment and, accordingly, we do not report asset information by operating segment.

17. Subsequent Events

On August 3, 2023, we acquired 100% of the issued share capital of PetMedix Ltd (PetMedix), a privately held research and development stage animal health biopharmaceutical company based in the United Kingdom, which develops antibody-based therapeutics for companion animals. The purchase price includes upfront cash consideration of approximately $111 million, excluding $19 million of cash acquired, $5 million in cash withheld for customary post-closing adjustments, and contingent consideration up to $100 million based on the achievement of certain milestones. There are additional contingent payments to be made to the seller upon receipt of payments from a third party related to a preexisting collaboration arrangement between PetMedix and the third party. The initial accounting for this acquisition is incomplete, pending valuation of contingent consideration, and identification and measurement of the assets acquired and liabilities assumed.

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 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 animal 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. 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.

Our operating environment

For a description of our operating environment, including factors which could materially affect our business, financial condition, or future results, see "Our Operating Environment" in the MD&A of our 2022 Annual Report on Form 10-K. Set forth below are updates to certain of the factors disclosed in our 2022 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: the decline in global macroeconomic conditions, inflation, global supply chain disruption, Russia’s invasion of Ukraine, geopolitical tensions with and economic uncertainty in China, variability in distributor inventory stocking levels as a result of expected demand and promotional activities, weather patterns, herd management decisions, regulatory actions, competitive dynamics, disease outbreaks, product and geographic mix, timing of price increases and timing of investment decisions.

Global Supply Chain Disruption

We are seeing improvements and recovery in supply for certain products as compared to the prior year. However, we continue to have supply chain challenges for other products and component parts, as well as competition for manufacturing inputs. Our global manufacturing team remains committed to addressing specific issues with ongoing supply chain optimizations, controlled launches for new products in additional markets and customer coordination.

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 six months ended June 30, 2023, 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 six months ended June 30, 2023, approximately 56% of our total revenue was in U.S. dollars. Our year-over-year total revenue growth was unfavorably impacted by approximately 2% 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 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.

Three months ended June 30, 2023 vs. three months ended June 30, 2022

Amortization of intangible assets was $37 million in the three months ended June 30, 2023 and 2022. An increase in amortization due to intangible assets acquired during 2022 was offset by the effect of asset impairments taken in 2022 and assets that became fully amortized during 2022.

Six months ended June 30, 2023 vs. six months ended June 30, 2022

Amortization of intangible assets decreased in the six months ended June 30, 2023 versus the comparable prior year period primarily due to asset impairments taken in 2022 and assets that became fully amortized during 2022, partially offset by intangible assets acquired during 2022.

Interest expense, net of capitalized interest, increased in the three and six months ended June 30, 2023 versus the comparable prior year periods. The increases were primarily as a result of higher interest rates on the $1.35 billion aggregate principal amount of our 2022 senior notes issued in November 2022 as compared to the 2013 senior notes redeemed in February 2023, upon maturity. The six months ended June 30, 2023 also included a higher debt balance during a portion of the current period. These increases were partially offset by higher gains on foreign exchange derivative instruments as compared to the prior year periods.

Three months ended June 30, 2023 vs. three months ended June 30, 2022

The change in Other (income)/deductions—net in the three months ended June 30, 2023 versus the comparable prior year period was primarily as a result of a gain on the sale of a majority interest in our pet insurance business and higher interest income in the current period due to higher interest rates on cash balances denominated in the U.S. dollar, partially offset by certain asset impairment charges related to our precision animal health business.

Six months ended June 30, 2023 vs. six months ended June 30, 2022

The change in Other (income)/deductions—net in the six months ended June 30, 2023 versus the comparable prior year period was primarily as a result of a gain on the sale of a majority interest in our pet insurance business, higher interest income in the current period due to higher interest rates on cash balances denominated in the U.S. dollar and royalty-related income that was predominantly associated with a settlement for underpayment of royalties in prior periods, partially offset by certain asset impairment charges related to our precision animal health business.

Effective tax rate	23.2		%	21.0		%		22.2		%	19.6		%

Our effective tax rate was 23.2% and 21.0% for the three months ended June 30, 2023 and 2022, respectively, and 22.2% and 19.6% for the six months ended June 30, 2023 and 2022, respectively. The higher effective tax rates for the three and six months ended June 30, 2023, compared with the three and six months ended June 30, 2022, were attributable to a higher net discrete tax expense mainly related to changes to prior years' tax positions and a less favorable jurisdictional mix of earnings (which includes the impact of the location of earnings and repatriation costs), partially offset by a higher benefit in the U.S. related to foreign-derived intangible income. 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.

Three months ended June 30, 2023 vs. three months ended June 30, 2022

U.S. operating segment

U.S. segment revenue increased by $74 million, or 7%, in the three months ended June 30, 2023, compared with the three months ended June 30, 2022, reflecting an increase of $64 million in companion animal products and $10 million in livestock products.

•Companion animal revenue growth was driven primarily by increased sales of our key dermatology portfolio, small animal vaccines, our monoclonal antibody (mAb) product for osteoarthritis (OA) pain, Solensia, and small animal diagnostics.

•Livestock revenue grew due to cattle and poultry, partially offset by a decline in swine. Sales of cattle products grew mainly due to increased sales of Draxxin resulting from a favorable comparable quarter versus the prior year. Sales of products in our poultry portfolio grew primarily due to increases in vaccines and medicated feed additives. Sales of swine products declined due to decreased disease prevalence.

U.S. segment earnings increased by $46 million, or 7%, in the three months ended June 30, 2023, compared with the three months ended June 30, 2022, primarily due to higher revenue, partially offset by higher cost of sales and operating expenses.

International operating segment

International segment revenue increased by $52 million, or 6%, in the three months ended June 30, 2023, compared with the three months ended June 30, 2022. Operational revenue increased by $100 million, or 11%, driven by growth of $80 million in companion animal products and $20 million in livestock products.

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

•Livestock operational revenue growth was due to increased sales of poultry, fish and cattle products, partially offset by a decline in swine. 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 and Chile. Sales of cattle products grew due to price and supply recovery, partially offset by unfavorable market conditions in key and emerging markets. Sales of swine products declined due to supply constraints.

•Additionally, International segment revenue was unfavorably impacted by foreign exchange which decreased revenue by $48 million, or 5%, primarily driven by the Argentinian peso, Australian dollar, Chinese renminbi, Canadian dollar and Turkish lira.

International segment earnings increased by $19 million, or 4%, in the three months ended June 30, 2023, compared with the three months ended June 30, 2022. Operational earnings growth was $23 million, or 5%, primarily due to higher revenue, partially offset by higher cost of sales and operating expenses.

Six months ended June 30, 2023 vs. six months ended June 30, 2022

U.S. operating segment

U.S. segment revenue increased by $59 million, or 3%, in the six months ended June 30, 2023, compared with the six months ended June 30, 2022, reflecting an increase of $11 million in companion animal products and $48 million in livestock products.

•Companion animal revenue increased due to our mAb product for OA pain, Solensia, small animal vaccines, key dermatology and small animal diagnostics, partially offset by lower sales of small animal parasiticides and anti-infection products. Strong growth in the second quarter was primarily 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 grew due to cattle and poultry, partially offset by a decline in swine. Sales of cattle products grew due to improved supply of key products and higher volume of anti-infective 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 decreased by $10 million, or 1%, in the six months ended June 30, 2023, compared with the six months ended June 30, 2022, primarily due to higher cost of sales and operating expenses, partially offset by higher revenue, which was tempered by the first quarter impacts detailed above.

International operating segment

International segment revenue increased by $82 million, or 4%, in the six months ended June 30, 2023, compared with the six months ended June 30, 2022. Operational revenue increased by $195 million, or 10%, driven by growth of $129 million in companion animal products and $66 million in livestock products.

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

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

•Additionally, International segment revenue was unfavorably impacted by foreign exchange which decreased revenue by $113 million, or 6%, primarily driven by the Argentinian peso, Chinese renminbi, euro, Australian dollar and British pound.

International segment earnings increased by $16 million, or 2%, in the six months ended June 30, 2023, compared with the six months ended June 30, 2022. Operational earnings growth was $47 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.

Three months ended June 30, 2023 vs. three months ended June 30, 2022

Other business activities net loss increased by $5 million in the three months ended June 30, 2023, compared with the three months ended June 30, 2022, reflecting an increase in R&D costs due to an increase in certain compensation-related costs to support innovation and an increase in operating costs, as well as lower earnings in our human health business, partially offset by timing of spend in project investments and favorable foreign exchange.

Six months ended June 30, 2023 vs. six months ended June 30, 2022

Other business activities net loss increased by $21 million in the six months ended June 30, 2023, compared with the six months ended June 30, 2022, reflecting an increase in R&D costs due to an increase in certain compensation-related costs to support innovation and an increase in operating costs, 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 diagnostic 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

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

32 |

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-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 Condensed Consolidated Financial Statements—Note 15. 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:

	Three Months Ended					Six Months Ended
	June 30,				%	June 30,				%
(MILLIONS OF DOLLARS)	2023		2022		Change	2023		2022		Change

Non-GAAP adjusted net income(a)	$	652	$	567	15	$	1,259	$	1,192	6

*Calculation not meaningful

(a)    The effective tax rate on adjusted pretax income was 21.5% and 20.7% for the three months ended June 30, 2023 and 2022, respectively, and 21.0% and 19.7% for the six months ended June 30, 2023 and 2022, respectively.

The higher effective tax rates for the three and six months ended June 30, 2023, compared with the three and six months ended June 30, 2022, were attributable to a higher net discrete tax expense mainly related to changes to prior years' tax positions and a less favorable jurisdictional mix of earnings (which includes the impact of the location of earnings and repatriation costs), partially offset by a higher benefit in the U.S. related to foreign-derived intangible income. Jurisdictional mix of earning can vary depending on repatriation decision, 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:

	Three Months Ended					Six Months Ended
	June 30,				%	June 30,				%
	2023		2022		Change	2023		2022		Change
Earnings per share—diluted(a):

Analysis of the condensed 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 Condensed Consolidated Financial Statements.

Analysis of the condensed consolidated balance sheets

June 30, 2023 vs. December 31, 2022

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 the increase in demand and build-up of certain products, as well as lower sales than anticipated for certain products.

Other current assets increased primarily due to higher value-added tax receivables for our international markets, the timing of tax benefits recognized and an increase in collateral posted related to derivative contracts, partially offset by the mark-to-market adjustment of derivative instruments.

Property, plant and equipment increased primarily as a result of capital spending, partially offset by depreciation expense.

Identifiable intangible assets, less accumulated amortization decreased primarily as a result of amortization expense, the impact of foreign exchange and the impairment of certain intangible assets. See Notes to Consolidated Financial Statements - Note 11. Goodwill and Other Intangible Assets.

Other noncurrent assets increased primarily due to the retained noncontrolling investment following the sale of a majority interest in our pet insurance business. See Notes to Consolidated Financial Statements - Note 5. Acquisitions and Divestitures.

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

35 |

Accrued compensation and related items decreased due to the payments of 2022 annual incentive bonuses, savings plan contributions to eligible employees and payments for sales incentive bonuses, partially offset by the accrual of 2023 annual incentive bonuses, sales incentive bonuses and savings plan contributions to eligible employees.

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

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.

Operating activities

Six months ended June 30, 2023 vs. six months ended June 30, 2022

Net cash provided by operating activities was $732 million for the six months ended June 30, 2023, compared with $645 million for the six months ended June 30, 2022. The increase in operating cash flows was primarily attributable to the timing of receipts and payments in the ordinary course of business and higher net income as adjusted by non-cash items, partially offset by the inventory build-up of certain products for increased demand and to mitigate potential supply constraints.

Investing activities

Six months ended June 30, 2023 vs. six months ended June 30, 2022

Our net cash used in investing activities was $296 million for the six months ended June 30, 2023, compared with net cash used in investing activities of $321 million for the six months ended June 30, 2022. The net cash used in investing activities for the six months ended June 30, 2023 was primarily due to capital expenditures, partially offset by net proceeds on the sale of a majority interest in our pet insurance business. The net cash used in investing activities for the six months ended June 30, 2022 was primarily due to capital expenditures and acquisitions, partially offset by net proceeds from derivative instrument activity.

Financing activities

Six months ended June 30, 2023 vs. six months ended June 30, 2022

Our net cash used in financing activities was $2,296 million for the six months ended June 30, 2023, compared with net cash used in financing activities of $1,155 million for the six months ended June 30, 2022. The net cash used in financing activities for the six months ended June 30, 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. The net cash used in financing activities for the six months ended June 30, 2022 was primarily attributable to 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.

36 |

Selected measures of liquidity and capital resources

Certain relevant measures of our liquidity and capital resources follow:

	June 30,		December 31,
(MILLIONS OF DOLLARS)	2023		2022
Cash and cash equivalents	$	1,717	$	3,581
Accounts receivable, net(a)	1,322		1,215
Short-term borrowings	2		2
Current portion of long-term debt	—		1,350
Long-term debt	6,555		6,552
Working capital	4,414		4,339
Ratio of current assets to current liabilities	3.50:1		2.37:1

(a)    Accounts receivable are usually collected over a period of 45 to 75 days. For the six months ended June 30, 2023 compared with December 31, 2022, the number of days that accounts receivables were outstanding 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 condensed consolidated balance sheets and Analysis of the condensed 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. The credit facility replaced the company's existing revolving credit facility dated as of December 2016. 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. In addition, the credit facility contains other customary covenants.

We were in compliance with all financial covenants as of June 30, 2023 and December 31, 2022. There were no amounts drawn under the credit facility as of June 30, 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 June 30, 2023, we had access to $52 million of lines of credit which expire at various times and are generally renewed annually. There was $2 million of borrowings outstanding related to these facilities as of June 30, 2023 and 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.

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 will 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 future financing.

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.

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:

	Commercial Paper	Long-term Debt		Date of Last Action
Name of Rating Agency	Rating	Rating	Outlook
Moody’s	P-2	Baa1	Stable	August 2017
S&P	A-2	BBB	Stable	December 2016

Share repurchase program

In December 2021, our Board of Directors authorized a $3.5 billion multi-year share repurchase program. As of June 30, 2023, there was $2.0 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 the first six months of 2023, 3.6 million shares were repurchased for $607 million, which excludes a $5 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 June 30, 2023 and December 31, 2022, recorded amounts for the estimated fair value of these indemnifications are not material.

New accounting standards

There were no accounting standards that were recently issued but not adopted as of June 30, 2023 that the Company expects to have a material impact on its condensed consolidated financial statements.

Forward-looking statements and factors that may affect future results

This report contains “forward-looking” statements. We intend such forward-looking statements to be covered by the safe harbor provisions for forward-looking statements contained in Section 27A of the Securities Act of 1933 and Section 21E of the Securities Exchange Act of 1934. We generally identify forward-looking statements by using words such as “anticipate,” “estimate,” “could,” “expect,” “intend,” “project,” “plan,” “predict,” “believe,” “seek,” “continue,” “outlook,” “objective,” “target,” “may,” “might,” “will,” “should,” “can have,” “likely” or the negative version of these words or comparable words or by using future dates in connection with any discussion of future performance, actions or events.

In particular, forward-looking statements include statements relating to our future actions, business plans or prospects, prospective products, product approvals or products under development, product and supply chain disruptions, R&D costs, timing and likelihood of success, future operating or financial performance, future results of current and anticipated products and services, the impact of the COVID-19 pandemic, strategies, sales efforts, expenses, production efficiencies, production margins, anticipated timing of generic market entries, integration of acquired businesses, interest rates, tax rates, changes in tax regimes and laws, foreign exchange rates, growth in emerging markets, the outcome of contingencies, such as legal proceedings, plans related to share repurchases and dividends, government regulation and financial results. These statements are not guarantees of future performance, actions or events. Forward-looking statements are subject to risks and uncertainties, many of which are beyond our control, and are based on assumptions that could prove to be inaccurate. Among the factors that could cause actual results to differ materially from past results and future plans and projected future results are the following:

•unanticipated safety, quality or efficacy concerns or issues about our products,

38 |

•the possible impact and timing of competing products, including generic alternatives, on our products and our ability to compete against such products;

•the decline in global economic conditions, including Russia's invasion of Ukraine, and inflation;

•the economic, political, legal and business environment of the foreign jurisdictions in which we do business;

•disruptive innovations and advances in medical practices and technologies;

•consolidation of our customers and distributors;

•changes in the distribution channel for companion animal products;

•the impact of the COVID-19 global pandemic on our business, global supply chain, customers and workforce;

•an outbreak of infectious disease carried by animals;

•restrictions and bans on the use of and consumer preferences regarding antibacterials in food-producing animals;

•perceived adverse effects linked to the consumption of food derived from animals that utilize our products or animals generally;

•increased regulation or decreased governmental support relating to the raising, processing or consumption of food-producing animals;

•failure to successfully acquire businesses, license rights or products, integrate businesses, form and manage alliances or divest businesses;

•adverse weather conditions and the availability of natural resources;

•the impact of climate change on our activities and the activities of our customers and suppliers, including, for example, altered distribution and intensity of rainfall, prolonged droughts or flooding, increased frequency of wildfires and other natural disasters, rising sea levels, and rising heat index;

•failure of our R&D, acquisition and licensing efforts to generate new products and product lifecycle innovations;

•difficulties or delays in the development or commercialization of new products;

•product launch delays, inventory shortages, recalls or unanticipated costs caused by manufacturing problems and capacity imbalances;

•fluctuations in foreign exchange rates and potential currency controls;

•legal factors, including product liability claims, antitrust litigation and governmental investigations, including tax disputes, environmental concerns, commercial disputes and patent disputes with branded and generic competitors, any of which could preclude commercialization of products or negatively affect the profitability of existing products;

•failure to protect our intellectual property rights or to operate our business without infringing the intellectual property rights of others;

•a cyber-attack, information security breach or other misappropriation of our data;

•quarterly fluctuations in demand and costs;

•governmental laws and regulations affecting domestic and foreign operations, including without limitation, tax obligations and changes affecting the tax treatment by the U.S. of income earned outside the U.S. that may result from pending or possible future proposals;

•governmental laws and regulations affecting our interactions with veterinary healthcare providers; and

•the other factors set forth under "Risk Factors" in Item 1A. of Part I of our 2022 Annual Report on Form 10-K.

However, there may also be other risks that we are unable to predict at this time. These risks or uncertainties may cause actual results to differ materially from those contemplated by a forward-looking statement. 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.

Item 3.    Quantitative and Qualitative Disclosures About Market Risk

A significant portion of our revenue and costs are exposed to changes in foreign exchange rates. In addition, our outstanding borrowings may be subject to risk from changes in interest rates and foreign exchange rates. The overall objective of our financial risk management program is to seek to minimize the impact of foreign exchange rate movements and interest rate movements on our earnings. We manage these financial exposures through operational means and by using certain financial instruments. These practices may change as economic conditions change.

For a complete discussion of our exposure to interest rate and foreign exchange risk, refer to Item 7A. Quantitative and Qualitative Disclosures About Market Risk in our Annual Report on Form 10-K for the year ended December 31, 2022. There have been no material changes from the information discussed therein.

Item 4.    Controls and Procedures

Disclosure Controls and Procedures

An evaluation was carried out under the supervision and with the participation of the company's management, including our Chief Executive Officer and Chief Financial Officer, of the effectiveness of the design and operation of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934). Based upon that evaluation as of June 30, 2023, the company's Chief Executive Officer and Chief Financial Officer concluded that the company's disclosure controls and procedures are effective at a reasonable level of assurance in alerting them in a timely manner to material information required to be disclosed in our periodic reports filed with the SEC.

Changes in Internal Control over Financial Reporting

During our most recent fiscal quarter, there has not been any change in our internal control over financial reporting (as such term is defined in Rules 13a-15(f) and 15d-15(f) under the Securities Exchange Act of 1934) that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

A. Revenue from Product Sales

We offer a diversified portfolio of products which allows us to capitalize on local and regional customer needs. 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. Many of our top-selling product lines are distributed across both of our operating segments, leveraging our research and development (R&D) operations and manufacturing and supply chain network.

Over the course of our history, we have focused on developing a diverse portfolio of animal health products, including medicines, vaccines and diagnostics, complemented by biodevices, genetic tests and a range of services. We refer to all different brands of a particular product, or its dosage forms for all species, as a product line. We have approximately 300 comprehensive product lines, including products for both companion animals and livestock within each of our major product categories.

Our major product categories are:

•parasiticides: products that prevent or eliminate external and internal parasites such as fleas, ticks and worms;

•vaccines: biological preparations that help prevent diseases of the respiratory, gastrointestinal and reproductive tracts or induce a specific immune response;

•dermatology products: products that relieve itch associated with allergic conditions and atopic dermatitis;

•other pharmaceutical products: pain and sedation, antiemetic, reproductive, and oncology products;

•anti-infectives: products that prevent, kill or slow the growth of bacteria, fungi or protozoa;

•animal health diagnostics: testing and analysis of blood, urine and other animal samples and related products and services, including point-of-care diagnostic products, instruments and reagents, rapid immunoassay tests, reference laboratory kits and services and blood glucose monitors; and

•medicated feed additives: products added to animal feed that provide medicines to livestock.

Our remaining revenue is derived from other non-pharmaceutical product categories, such as nutritionals, as well as products and services in biodevices, genetic tests and precision animal health.

Our companion animal products help extend and improve the quality of life for pets; increase convenience and compliance for pet owners; and help veterinarians improve the quality of their care and the efficiency of their businesses. Growth in the companion animal medicines, vaccines and diagnostics sector is driven by economic development, related increases in disposable income and increases in pet ownership and spending on pet care. Companion animals are also living longer, deepening the human-animal bond, receiving increased medical treatment and benefiting from advances in animal health medicine, vaccines and diagnostics.

Our livestock products primarily help prevent or treat diseases and conditions to allow veterinarians and producers to care for their animals and to enable the cost-effective production of safe, high-quality animal protein. Human population growth and increasing standards of living are important long-term growth drivers for our livestock products in three major ways. First, population growth and increasing standards of living drive demand for improved nutrition, particularly through increased consumption of animal protein. Second, population growth leads to greater natural resource constraints driving a need for enhanced productivity. Finally, as standards of living improve and the global food chain faces increased scrutiny, there is more focus on food quality, safety and reliability of supply.

The following tables present our revenue disaggregated by geographic area, species and major product category:

Acquisitions

5. Acquisitions and Divestitures

A. Acquisitions

In 2022, we completed the acquisition of Basepaws, a privately held petcare genetics company based in the U.S., which provides pet owners with genetic tests, analytics and early health risk assessments that can help manage the health, wellness and quality of care for their pets. We also completed the acquisition of NewMetrica, a privately held company based in Scotland, that provides scientifically-developed instruments to measure quality of life in companion animals. These transactions did not have a material impact on our condensed consolidated financial statements.

During 2021, we entered into an agreement to acquire Jurox, a privately held animal health company based in Australia, which develops, manufactures and markets a wide range of veterinary medicines for treating companion animals and livestock. On September 30, 2022, after satisfying all customary closing conditions, including clearance from the Australian Competition and Consumer Commission, we completed the acquisition of Jurox. We acquired 100% of the outstanding shares for an aggregate cash purchase price of $226 million, which was adjusted to $240 million for cash and working capital and other adjustments as of the closing date. Net cash consideration transferred to the seller was $215 million during 2022 and $5 million for the six months ended June 30, 2023. The transaction was accounted for as a business combination, with the assets acquired and liabilities assumed measured at their respective acquisition date fair values. The table below presents the preliminary fair values allocated to the assets and liabilities of Jurox as of the acquisition date:

Total consideration	$	240

(a)        Acquired inventory is comprised of finished goods, work in process and raw materials. The fair value of finished goods was determined based on net realizable value adjusted for the costs of the selling effort, a reasonable profit allowance for the selling effort, and estimated holding costs. The fair value of work in process was determined based on net realizable value adjusted for costs to complete the manufacturing process, costs of the selling effort, a reasonable profit allowance for the remaining manufacturing and selling effort, and an estimate of holding costs. The fair value of raw materials was determined to approximate book value.

(b)    Property, plant and equipment is comprised of buildings, machinery and equipment, land, construction in progress and furniture and fixtures. The fair value was primarily determined using a reproduction/replacement cost approach which measures the value of an asset by estimating the cost to acquire or construct comparable assets adjusted for age and condition of the asset.

(c)    Identifiable intangible assets consist of developed technology rights. The fair value of identifiable intangible assets was determined using the income approach, which includes a forecast of expected future cash flows. For additional information regarding identifiable intangible assets, see Note 11. Goodwill and Other Intangible Assets.

(d)        Goodwill represents the excess of consideration transferred over the fair values of the assets acquired and liabilities assumed. It is allocated to our International segment and is primarily attributable to cost and revenue synergies including market share capture, elimination of cost redundancies and gain of cost efficiencies, and intangible assets such as assembled workforce which are not separately recognizable. The primary strategic purpose of the acquisition was to enhance the company’s existing product portfolio.

All amounts recorded are subject to final valuation. Any adjustments to our preliminary purchase price allocation identified during the measurement period, which will not exceed one year from the acquisition date, will be accounted for prospectively.

B. Divestitures

During the second quarter of 2023, we received net cash proceeds of $93 million ($99 million sales proceeds, net of cash sold of $6 million) for the sale of a majority interest in our pet insurance business, Pumpkin Insurance Services. For the three months ended June 30, 2023, we recorded a net pre-tax gain of $101 million within Other (income)/deductions—net, which includes $24 million related to the remeasurement of our retained noncontrolling investment to fair value.

Restructuring Charges and Other Costs Associated with Acquisitions and Cost-Reduction/Productivity Initiatives

6. Restructuring Charges and Other Costs Associated with Acquisitions, Cost-Reduction and Productivity
Initiatives

In connection with our cost-reduction/productivity initiatives, we typically incur costs and charges associated with site closings and other facility rationalization actions, workforce reductions and the expansion of shared services, including the development of global systems. In connection with our acquisition activity, we typically incur costs and charges associated with executing the transactions, integrating the acquired operations, which may include expenditures for consulting and the integration of systems and processes, product transfers and restructuring the consolidated company, which may include charges related to employees, assets and activities that will not continue in the consolidated company. All operating functions can be impacted by these actions, including sales and marketing, manufacturing and R&D, as well as functions such as business technology, shared services and corporate operations.

The components of costs incurred in connection with restructuring initiatives, acquisitions and cost-reduction/productivity initiatives are as follows:

Income Tax Disclosure [Abstract]

Income Taxes

8. Income Taxes

A. Taxes on Income

Our effective tax rate was 23.2% and 21.0% for the three months ended June 30, 2023 and 2022, respectively, and 22.2% and 19.6% for the six months ended June 30, 2023 and 2022, respectively. The higher effective tax rates for the three and six months ended June 30, 2023, compared with the three and six months ended June 30, 2022, were attributable to a higher net discrete tax expense mainly related to changes to prior years' tax positions and a less favorable jurisdictional mix of earnings (which includes the impact of the location of earnings and repatriation costs), partially offset by a higher benefit in the U.S. related to foreign-derived intangible income. 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.

In 2022, the company implemented an initiative to maximize its cash position in the U.S. This initiative resulted in a tax benefit in the U.S. in connection with a prepayment from a related foreign entity in Belgium which qualifies as foreign-derived intangible income; however, this income tax benefit was deferred to 2023 and 2024. A portion of this benefit was recognized during the three and six months ended June 30, 2023.

B. Deferred Taxes

As of June 30, 2023, the total net deferred income tax asset of $71 million is included in Noncurrent deferred tax assets ($192 million) and Noncurrent deferred tax liabilities ($121 million).

As of December 31, 2022, the total net deferred income tax asset of $31 million is included in Noncurrent deferred tax assets ($173 million) and Noncurrent deferred tax liabilities ($142 million).

C. Tax Contingencies

As of June 30, 2023, the net tax liabilities associated with uncertain tax positions of $217 million (exclusive of interest and penalties related to uncertain tax positions of $27 million) are included in Noncurrent deferred tax assets and Other noncurrent assets ($1 million) and Other taxes payable ($216 million).

As of December 31, 2022, the net tax liabilities associated with uncertain tax positions of $194 million (exclusive of interest and penalties related to uncertain tax positions of $19 million) are included in Noncurrent deferred tax assets and Other noncurrent assets ($2 million) and Other taxes payable ($192 million).

The increase in net tax liabilities associated with uncertain tax positions, as well as the increase in interest and penalties, is mainly attributable to a net discrete tax expense related to changes in prior years' uncertain tax positions recognized in the three and six months ended June 30, 2023.

Our tax liabilities for uncertain tax positions relate primarily to issues common among multinational corporations. Any settlements or statute of limitations expirations could result in a significant decrease in our uncertain tax positions. Substantially all of these unrecognized tax benefits, if recognized, would impact our effective income tax rate. We do not expect that within the next twelve months any of our uncertain tax positions could significantly decrease as a result of settlements with taxing authorities or the expiration of the statutes of limitations. Our assessments are based on estimates and assumptions that have been deemed reasonable by management, but our estimates of uncertain tax positions and potential tax benefits may not be representative of actual outcomes, and any variation from such estimates could materially affect our financial statements in the period of settlement or when the statutes of limitations expire, as we treat these events as discrete items in the period of resolution. Finalizing audits with the relevant taxing authorities can include formal administrative and legal proceedings, and, as a result, it is difficult to estimate the timing and range of possible changes related to our uncertain tax positions, and such changes could be significant.

Financial Instruments

9. Financial Instruments

A. Debt

Credit Facilities

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 2016. 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. In addition, the credit facility contains other customary covenants.

We were in compliance with all financial covenants as of June 30, 2023 and December 31, 2022. There were no amounts drawn under the credit facility as of June 30, 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 June 30, 2023, we had access to $52 million of lines of credit which expire at various times and are generally renewed annually. There was $2 million of borrowings outstanding related to these facilities as of June 30, 2023 and December 31, 2022.

Commercial Paper Program

In February 2013, we entered into a commercial paper program with a capacity of up to $1.0 billion. As of June 30, 2023 and December 31, 2022, there was no commercial paper outstanding under this program.

Senior Notes and Other Long-Term Debt

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-leaseback 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.

The components of our long-term debt are as follows:

	June 30,		December 31,
(MILLIONS OF DOLLARS)	2023		2022
3.250% 2013 senior notes due 2023	$	—	$	1,350

Interest Expense

Interest expense, net of capitalized interest, was $58 million and $121 million for the three and six months ended June 30, 2023, respectively, and $53 million and $106 million for the three and six months ended June 30, 2022, respectively. Capitalized interest expense was $6 million and $12 million for the three and six months ended June 30, 2023, respectively, and $6 million and $11 million for the three and six months ended June 30, 2022, respectively.

B. Derivative Financial Instruments

Foreign Exchange Risk

A significant portion of our revenue, earnings and net investment in foreign affiliates is exposed to changes in foreign exchange rates. 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. Depending on market conditions, foreign exchange risk is also managed through the use of various derivative financial instruments. These derivative financial instruments serve to manage the exposure of our net investment in certain foreign operations to changes in foreign exchange rates and protect net income against the impact of translation into U.S. dollars of certain foreign exchange-denominated transactions.

All derivative financial instruments used to manage foreign currency risk are measured at fair value and are reported as assets or liabilities on the Condensed Consolidated Balance Sheets. The derivative financial instruments primarily offset exposures in the British pound, Canadian dollar, Chinese yuan, euro, Japanese yen and Norwegian krone. Changes in fair value are reported in earnings or in Accumulated other comprehensive income/(loss), depending on the nature and purpose of the financial instrument, as follows:

•For foreign currency forward-exchange contracts not designated as hedging instruments, we recognize the gains and losses that are used to offset the same foreign currency assets or liabilities immediately into earnings along with the earnings impact of the items they generally offset. These contracts essentially take the opposite currency position of that reflected in the month-end balance sheet to counterbalance the effect of any currency movement. The vast majority of the foreign currency forward-exchange contracts mature within 60 days and all mature within three years.

•For foreign exchange derivative instruments that are designated as hedging instruments against our net investment in foreign operations, changes in the fair value are recorded as a component of cumulative translation adjustment within Accumulated other comprehensive income/(loss) and reclassified into earnings when the foreign investment is sold or substantially liquidated. These instruments include cross-currency interest rate swaps and foreign currency forward-exchange contracts. Gains and losses excluded from the assessment of hedge effectiveness are recognized in earnings (Interest expense, net of capitalized interest). The cash flows from these contracts are reflected within the investing section of our Condensed Consolidated Statements of Cash Flows. These contracts have varying maturities of

up to two years.

Interest Rate Risk

The company may use interest rate swap contracts on certain investing and borrowing transactions to manage its net exposure to interest rates and to reduce its overall cost of borrowing.

•In anticipation of issuing fixed-rate debt, we may use forward-starting interest rate swaps that are designated as cash flow hedges to hedge against changes in interest rates that could impact expected future issuances of debt. Unrealized gains or losses on the forward-starting interest rate swaps are reported in Accumulated other comprehensive loss and are recognized in earnings over the life of the future fixed rate notes. When the company discontinues hedge accounting because it is no longer probable that an anticipated transaction will occur within the originally expected period of execution, or within an additional two-month period thereafter, changes to fair value accumulated in other comprehensive income are recognized immediately in earnings.

•During the period from 2019 to 2022, we entered into forward-starting interest rate swaps with an aggregate notional value of $650 million. We designated these swaps as cash flow hedges against interest rate exposure related principally to the issuance of fixed-rate debt to refinance our 3.250% 2013 senior notes due 2023. Upon issuance of our 2022 senior notes, we terminated these contracts and received $114 million in cash from the counterparties for settlement, included in Net cash provided by operating activities in the Consolidated Statements of Cash Flows. The settlement amount, which represented the fair value of the contracts at the time of termination, was recorded in Accumulated other comprehensive loss, and will be amortized into income (offset to Interest expense, net of capitalized interest) over the life of the 5.600% 2022 senior notes due 2032.

•As of June 30, 2023, we had outstanding forward-starting interest rate swaps, having an effective date and mandatory termination date in March 2026, to hedge against interest rate exposure related principally to the anticipated future issuance of fixed-rate debt to be used primarily to refinance our 4.500% 2015 senior notes due 2025.

•We may use fixed-to-floating interest rate swaps that are designated as fair value hedges to hedge against changes in the fair value of certain fixed-rate debt attributable to changes in the benchmark Secured Overnight Financing Rate (SOFR). These derivative instruments effectively convert a portion of the company’s long-term debt from fixed-rate to floating-rate debt based on the daily SOFR rate plus a spread. Gains or losses on the fixed-to-floating interest rate swaps due to changes in SOFR are recorded in Interest expense, net of capitalized interest. Changes in the fair value of the fixed-to-floating interest rate swaps are offset by changes in the fair value of the underlying fixed-rate debt. As of June 30, 2023, we had outstanding fixed-to-floating interest rate swaps that correspond to a portion of the 3.900% 2018 senior notes due 2028 and the 2.000% senior notes due 2030. The amounts recorded during the three and six months ended June 30, 2023 for changes in the fair value of these hedges are not material to our condensed consolidated financial statements.

During the first quarter of 2023, we executed amendments to certain of our interest rate swap contracts, which changed the floating rate index from LIBOR to SOFR. These amendments did not have a material impact on our condensed consolidated financial statements.

The company’s derivative transactions are subject to master netting agreements that mitigate credit risk by permitting net settlement of transactions with the same counterparty. The company also has collateral security agreements with certain of its counterparties. Under these collateral security agreements either party is required to post cash collateral when the net fair value of derivative instruments covered by the collateral agreement exceeds contractually established thresholds. At June 30, 2023, there was $2 million of collateral received and $37 million of collateral posted related to derivative instruments recorded in Other current liabilities and Other current assets, respectively. At December 31, 2022, there was $8 million of collateral received and $21 million of collateral posted related to derivative instruments recorded in Other current liabilities and Other current assets, respectively.

We use a market approach in valuing financial instruments on a recurring basis. Our derivative financial instruments are measured at fair value on a recurring basis using Level 2 inputs in the calculation of fair value.

The amounts of net losses on derivative instruments not designated as hedging instruments, recorded in Other (income)/deductions—net, are as follows:

	Three Months Ended				Six Months Ended
	June 30,				June 30,

Foreign currency forward-exchange contracts	$	(20)	$	(20)	$	(36)	$	(26)

These amounts were substantially offset in Other (income)/deductions—net by the effect of changing exchange rates on the underlying foreign currency exposures.

The amounts of unrecognized net gains/(losses) on interest rate swap contracts, recorded, net of tax, in Accumulated other comprehensive loss, are as follows:

	Three Months Ended				Six Months Ended
	June 30,				June 30,
(MILLIONS OF DOLLARS)	2023		2022		2023		2022

The principal types of share-based awards available under the Equity Plan may include, but are not limited to, stock options, restricted stock and restricted stock units (RSUs), deferred stock units (DSUs), performance-vesting restricted stock units (PSUs) and other equity-based or cash-based awards.

The components of share-based compensation expense are as follows:

	Three Months Ended				Six Months Ended
	June 30,				June 30,
(MILLIONS OF DOLLARS)	2023		2022		2023		2022
Stock options / stock appreciation rights	$	2	$	3	$	3	$	5
RSUs / DSUs	10		8		17		17
PSUs	5		4		6		9
Share-based compensation expense—total(a)	$	17	$	15	$	26	$	31

(a) For the three and six months ended June 30, 2023 and 2022, we capitalized less than $1 million of share-based compensation expense to inventory.

During the six months ended June 30, 2023, the company granted 271,150 stock options with a weighted-average exercise price of $162.12 per stock option and a weighted-average fair value of $43.56 per stock option. The fair-value based method for valuing each Zoetis stock option grant on the grant date uses the Black-Scholes-Merton option-pricing model, which incorporates a number of valuation assumptions. The weighted-average fair value was estimated based on the following assumptions: risk-free interest rate of 3.84%; expected dividend yield of 0.92%; expected stock price volatility of 28.63%; and expected term of 4.2 years. In general, stock options granted prior to 2023 vest after three years of continuous service, while stock options granted in 2023 are subject to graded vesting over three years. The values determined through this fair-value based method generally are amortized on a straight-line basis over the vesting term into Cost of sales, Selling, general and administrative expenses, or Research and development expenses, as appropriate.

During the six months ended June 30, 2023, the company granted 267,535 RSUs, with a weighted-average grant date fair value of $162.18 per RSU. RSUs are accounted for using a fair-value-based method that utilizes the closing price of Zoetis common stock on the date of grant. In general, RSUs granted prior to 2023 vest after three years of continuous service from the grant date while RSUs granted in 2023 are subject to graded vesting over three years. The values generally are amortized on a straight-line basis over the vesting term into Cost of sales, Selling, general and administrative expenses, or Research and development expenses, as appropriate.

During the six months ended June 30, 2023, the company granted 99,626 PSUs with a weighted-average grant date fair value of $238.24 per PSU. PSUs are accounted for using a Monte Carlo simulation model. The units underlying the PSUs will be earned and vested over a three-year performance period, based upon the total shareholder return of the company in comparison to the total shareholder return of the companies comprising the S&P 500 stock market index at the start of the performance period, excluding companies that during the performance period are acquired or no longer publicly traded (Relative TSR). The weighted-average fair value was estimated based on volatility assumptions of Zoetis common stock and an average of the S&P 500 companies, which were 31.8% and 40.9%, respectively. Depending on the company’s Relative TSR performance at the end of the performance period, the recipient may earn from 0% to 200% of the target number of units. Vested units are settled in shares of the company’s common stock. PSU values are amortized on a straight-line basis over the vesting term into Cost of sales, Selling, general and administrative expenses, or Research and development expenses, as appropriate.

Commitments and Contingencies Disclosure [Abstract]

Commitments and Contingencies

15. Commitments and Contingencies

We and certain of our subsidiaries are subject to numerous contingencies arising in the ordinary course of business. For a discussion of our tax contingencies, see Note 8. Income Taxes.

A. Legal Proceedings

Our non-tax contingencies include, among others, the following:

•    Product liability and other product-related litigation, which can include injury, consumer, off-label promotion, antitrust and breach of contract claims.

•    Commercial and other matters, which can include product-pricing claims and environmental claims and proceedings.

•    Patent litigation, which typically involves challenges to the coverage and/or validity of our patents or those of third parties on various products or processes.

•    Government investigations, which can involve regulation by national, state and local government agencies in the U.S. and in other countries.

Certain of these contingencies could result in losses, including damages, fines and/or civil penalties, and/or criminal charges, which could be substantial.

We believe that we have strong defenses in these types of matters, but litigation is inherently unpredictable and excessive verdicts do occur. We do not believe that any of these matters will have a material adverse effect on our financial position. However, we could incur judgments, enter into settlements or revise our expectations regarding the outcome of certain matters, and such developments could have a material adverse effect on our results of operations or cash flows in the period in which the amounts are paid.

We have accrued for losses that are both probable and reasonably estimable. Substantially all of these contingencies are subject to significant uncertainties and, therefore, determining the likelihood of a loss and/or the measurement of any loss can be complex. Consequently, we are unable to estimate the range of reasonably possible loss in excess of amounts accrued. Our assessments are based on estimates and assumptions that have been deemed reasonable by management, but the assessment process relies on estimates and assumptions that may prove to be incomplete or inaccurate, and unanticipated events and circumstances may occur that might cause us to change those estimates and assumptions.

Amounts recorded for legal and environmental contingencies can result from a complex series of judgments about future events and uncertainties and can rely on estimates and assumptions.

The principal matters to which we are a party are discussed below. In determining whether a pending matter is significant for financial reporting and disclosure purposes, we consider both quantitative and qualitative factors in order to assess materiality, such as, among other things, the amount of damages and the nature of any other relief sought in the proceeding, if such damages and other relief are specified; our view of the merits of the claims and of the strength of our defenses; whether the action purports to be a class action and our view of the likelihood that a class will be certified by the court; the jurisdiction in which the proceeding is pending; any experience that we or, to our knowledge, other companies have had in similar proceedings; whether disclosure of the action would be important to a reader of our financial statements, including whether disclosure might change a reader’s judgment about our financial statements in light of all of the information about the company that is available to the reader; the potential impact of the proceeding on our reputation; and the extent of public interest in the matter. In addition, with respect to patent matters, we consider, among other things, the financial significance of the product protected by the patent.

Ulianopolis, Brazil

In February 2012, the Municipality of Ulianopolis (State of Para, Brazil) filed a complaint against Fort Dodge Saúde Animal Ltda. (FDSAL), a Zoetis entity, and five other large companies alleging that waste sent to a local waste incineration facility for destruction, but that was not ultimately destroyed as the facility lost its operating permit, caused environmental impacts requiring cleanup.

The Municipality is seeking recovery of cleanup costs purportedly related to FDSAL's share of all waste accumulated at the incineration facility awaiting destruction, and compensatory damages to be allocated among the six defendants. We believe we have strong arguments against the claim, including defense strategies against any claim of joint and several liability.

At the request of the Municipal prosecutor, in April 2012, the lawsuit was suspended for one year. Since that time, the prosecutor has initiated investigations into the Municipality's actions in the matter as well as the efforts undertaken by the six defendants to remove and dispose of their individual waste from the incineration facility. On October 3, 2014, the Municipal prosecutor announced that the investigation remained ongoing and outlined the terms of a proposed Term of Reference (a document that establishes the minimum elements to be addressed in the preparation of an Environmental Impact Assessment), under which the companies would be liable to withdraw the waste and remediate the area.

On March 5, 2015, we presented our response to the prosecutor’s proposed Term of Reference, arguing that the proposed terms were overly general in nature and expressing our interest in discussing alternatives to address the matter. The prosecutor agreed to consider our request to engage a technical consultant to conduct an environmental diagnostic of the contaminated area. On May 29, 2015, we, in conjunction with the other defendant companies, submitted a draft cooperation agreement to the prosecutor, which outlined the proposed terms and conditions for the engagement of a technical consultant to conduct the environmental diagnostic. On August 19, 2016, the parties and the prosecutor agreed to engage the services of a third-party consultant to conduct a limited environmental assessment of the site. The site assessment was conducted during June 2017, and a written report summarizing the results of the assessment was provided to the parties and the prosecutor in November 2017. The report noted that waste is still present on the site and that further (Phase II) environmental assessments are needed before a plan to manage that remaining waste can be prepared. On April 1, 2019, the defendants met with the Prosecutor to discuss the conclusions set forth in the written report. Following that discussion, on April 10, 2019, the Prosecutor issued a procedural order requesting that the defendants prepare and submit a technical proposal outlining the steps needed to conduct the additional Phase II environmental assessments. The defendants presented the technical proposal to the Prosecutor on October 21, 2019. On March 3, 2020, the Prosecutor notified the defendants that he submitted the proposal to the Ministry of the Environment for its review and consideration by the Prosecutor. On July 15, 2020, the Prosecutor recommended certain amendments to the proposal for the Phase II testing. On September 28, 2020, the parties and the Prosecutor agreed to the final terms and conditions concerning the cooperation agreement with respect to the Phase II testing. Due to the ongoing issues presented by the coronavirus (COVID-19) pandemic, the parties have been unable to secure a start date for the Phase II testing and have no timeline at this point when testing will begin.

Belgium Excess Profit Tax Regime

On February 14, 2019, the General Court of the European Union (General Court) annulled the January 11, 2016 decision of the European Commission (EC) that selective tax advantages granted by Belgium under its "excess profit" tax scheme constitute illegal state aid. As a result of the 2016 decision, the company recorded a net tax charge of approximately $35 million in the first half of 2016. On May 8, 2019, the EC filed an appeal to the decision of the General Court. On September 16, 2019, the EC opened separate in-depth investigations to assess whether Belgium excess profit rulings granted to 39 multinational companies, including Zoetis, constituted state aid for those companies. On September 16, 2021, the European Court of Justice upheld the EC’s decision that the Belgium excess profit ruling system is considered an aid scheme and referred the case back to the General Court to rule on open questions. On May 24, 2022, the General Court resumed all proceedings involved with the Excess Profit Rulings cases, including Zoetis. On June 23, 2022, as requested by the General Court, the company provided observations in relations to (i) the impact of the Court of Justice’s decision that the Belgium excess profit ruling system is considered an aid scheme and (ii) the impact of recent case laws by the General Court with regards to the existence of a selective advantage. On December 16, 2022, the company submitted observations on the conclusions drawn from the November 8, 2022 Fiat Chrysler Finance Europe and Ireland v Commission judgement, as requested by the General Court. A hearing by the General Court took place on February 15, 2023 and we are now awaiting a decision on our plea. The company has not reflected any potential benefits in its condensed consolidated financial statements as of June 30, 2023 as a result of the 2019 annulment. We will continue to monitor the developments of the appeal and its ultimate resolution.

B. Guarantees and Indemnifications

In the ordinary course of business and in connection with the sale of assets and businesses, we indemnify our counterparties against certain liabilities that may arise in connection with the transaction or related to activities prior to the 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 June 30, 2023, recorded amounts for the estimated fair value of these indemnifications were not material.

Segment Reporting [Abstract]

Segment Information

16. Segment Information

Operating Segments

We manage our operations through two geographic operating segments: the U.S. and International. Each operating segment has responsibility for its commercial activities. Within each of these operating segments, we offer a diversified product portfolio, including parasiticides, vaccines, dermatology, other pharmaceutical products, anti-infectives, animal health diagnostics and medicated feed additives, for both companion animal and livestock customers. Our chief operating decision maker uses the revenue and earnings of the two operating segments, among other factors, for performance evaluation and resource allocation.

Other Costs and Business Activities

Certain costs are not allocated to our operating segment results, such as costs associated with the following:

•    Other business activities, includes our Client Supply Services (CSS) 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 commercial segment.

•    Corporate, includes enabling functions such as information technology, facilities, legal, finance, human resources, business development, certain diagnostic costs and communications, among others. These costs also include certain compensation costs, certain procurement costs and other miscellaneous operating expenses not charged to our operating segments, as well as interest income and expense.

•Certain transactions and events such as (i) Purchase accounting adjustments, where we incur expenses associated with the amortization of fair value adjustments to inventory, intangible assets and property, plant and equipment; (ii) Acquisition-related activities, where we incur costs associated with acquiring and integrating newly acquired businesses, such as transaction costs and integration costs; and (iii) Certain significant items, which comprise substantive, unusual items that, either as a result of their nature or size, would not be expected to occur as part of our normal business on a regular basis, such as restructuring charges and implementation costs associated with our cost-reduction/productivity initiatives that are not associated with an acquisition, certain asset impairment charges, certain legal and commercial settlements and the impact of divestiture-related gains and losses.

•Other unallocated 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.

Segment Assets

We manage our assets on a total company basis, not by operating segment. Therefore, our chief operating decision maker does not regularly review any asset information by operating segment and, accordingly, we do not report asset information by operating segment.

Recently Adopted Accounting Standards and Recently Issued Accounting Standards

Recently Adopted Accounting Standards

Tax Contingencies

Our tax liabilities for uncertain tax positions relate primarily to issues common among multinational corporations. Any settlements or statute of limitations expirations could result in a significant decrease in our uncertain tax positions. Substantially all of these unrecognized tax benefits, if recognized, would impact our effective income tax rate. We do not expect that within the next twelve months any of our uncertain tax positions could significantly decrease as a result of settlements with taxing authorities or the expiration of the statutes of limitations. Our assessments are based on estimates and assumptions that have been deemed reasonable by management, but our estimates of uncertain tax positions and potential tax benefits may not be representative of actual outcomes, and any variation from such estimates could materially affect our financial statements in the period of settlement or when the statutes of limitations expire, as we treat these events as discrete items in the period of resolution. Finalizing audits with the relevant taxing authorities can include formal administrative and legal proceedings, and, as a result, it is difficult to estimate the timing and range of possible changes related to our uncertain tax positions, and such changes could be significant.

Legal Proceedings

A. Legal Proceedings

Our non-tax contingencies include, among others, the following:

•    Product liability and other product-related litigation, which can include injury, consumer, off-label promotion, antitrust and breach of contract claims.

•    Commercial and other matters, which can include product-pricing claims and environmental claims and proceedings.

•    Patent litigation, which typically involves challenges to the coverage and/or validity of our patents or those of third parties on various products or processes.

•    Government investigations, which can involve regulation by national, state and local government agencies in the U.S. and in other countries.

Certain of these contingencies could result in losses, including damages, fines and/or civil penalties, and/or criminal charges, which could be substantial.

We believe that we have strong defenses in these types of matters, but litigation is inherently unpredictable and excessive verdicts do occur. We do not believe that any of these matters will have a material adverse effect on our financial position. However, we could incur judgments, enter into settlements or revise our expectations regarding the outcome of certain matters, and such developments could have a material adverse effect on our results of operations or cash flows in the period in which the amounts are paid.

We have accrued for losses that are both probable and reasonably estimable. Substantially all of these contingencies are subject to significant uncertainties and, therefore, determining the likelihood of a loss and/or the measurement of any loss can be complex. Consequently, we are unable to estimate the range of reasonably possible loss in excess of amounts accrued. Our assessments are based on estimates and assumptions that have been deemed reasonable by management, but the assessment process relies on estimates and assumptions that may prove to be incomplete or inaccurate, and unanticipated events and circumstances may occur that might cause us to change those estimates and assumptions.

Amounts recorded for legal and environmental contingencies can result from a complex series of judgments about future events and uncertainties and can rely on estimates and assumptions.

The principal matters to which we are a party are discussed below. In determining whether a pending matter is significant for financial reporting and disclosure purposes, we consider both quantitative and qualitative factors in order to assess materiality, such as, among other things, the amount of damages and the nature of any other relief sought in the proceeding, if such damages and other relief are specified; our view of the merits of the claims and of the strength of our defenses; whether the action purports to be a class action and our view of the likelihood that a class will be certified by the court; the jurisdiction in which the proceeding is pending; any experience that we or, to our knowledge, other companies have had in similar proceedings; whether disclosure of the action would be important to a reader of our financial statements, including whether disclosure might change a reader’s judgment about our financial statements in light of all of the information about the company that is available to the reader; the potential impact of the proceeding on our reputation; and the extent of public interest in the matter. In addition, with respect to patent matters, we consider, among other things, the financial significance of the product protected by the patent.

Guarantees and Indemnifications

B. Guarantees and IndemnificationsIn the ordinary course of business and in connection with the sale of assets and businesses, we indemnify our counterparties against certain liabilities that may arise in connection with the transaction or related to activities prior to the 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 June 30, 2023, recorded amounts for the estimated fair value of these indemnifications were not material.

Segment Information

Operating Segments

We manage our operations through two geographic operating segments: the U.S. and International. Each operating segment has responsibility for its commercial activities. Within each of these operating segments, we offer a diversified product portfolio, including parasiticides, vaccines, dermatology, other pharmaceutical products, anti-infectives, animal health diagnostics and medicated feed additives, for both companion animal and livestock customers. Our chief operating decision maker uses the revenue and earnings of the two operating segments, among other factors, for performance evaluation and resource allocation.

•    Other business activities, includes our Client Supply Services (CSS) 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 commercial segment.
