EXECUTIVE COMMENTARY

"As an essential business supporting the global food supply and the care of people's pets during the pandemic, Zoetis demonstrated greater resiliency than expected in the second quarter, with 4% operational growth in revenue and 4% operational growth in adjusted net income," said Kristin Peck,

Chief Executive Officer of Zoetis. "Our strong companion animal portfolio, based on our internal innovations, helped offset some of the deeper challenges in the livestock market today."

"Looking ahead, we expect our overall revenue growth for the remainder of the year to be driven largely by companion animal products, especially parasiticides and our key dermatology portfolio, and we are raising our guidance to reflect our current outlook for the year. We will continue to invest in products that will strengthen the innovations and digital solutions that are needed by our customers across the continuum of care - from prediction and prevention to detection and treatment of diseases," said Peck.

QUARTERLY HIGHLIGHTS

Zoetis organizes and manages its commercial operations across two segments United States (U.S.) and International. Within these segments, the company delivers a diverse portfolio of products for companion animals and livestock, tailored to local trends and customer needs. In the second quarter of 2020

Revenue in the U.S. segment was $823 million, an increase of 6% compared with the second quarter of 2019. Sales of companion animal products increased 19% driven primarily by growth in the Simparica franchise, including the continued launch of Simparica Trio , the company's new triple combination parasiticide for dogs. Also contributing to growth was the company's key dermatology portfolio across both the Cytopoint and Apoquel brands. Additionally, companion animal sales benefited from the recent acquisitions of Platinum Performance and its nutritional product formulas, as well as a number of regional diagnostic reference labs. Sales of livestock products decreased 18% in the quarter. Disruptions in the food supply chain including reduced producer processing capacity and continued channel migration from dining out to preparing food at home impacted producer profitability and resulted in a decline across each of the cattle, swine and poultry portfolios. The decline in the cattle portfolio was also the result of continued unfavorable market conditions in beef and dairy, while swine product sales were negatively impacted by increased competition.

Revenue in the International segment was $708 million, a decrease of 5% on a reported basis and an increase of 3% operationally compared with the second quarter of 2019. Sales of companion animal products declined 3% on a reported basis and grew 2% on an operational basis. Growth resulted from increased sales of the company's key dermatology portfolio across both the Apoquel and Cytopoint brands, as well as the Simparica franchise, including the launch of Simparica Trio in Canada and certain markets in the EU. Sales of companion animal products in China continued to grow rapidly driven by strong underlying market dynamics. Growth in companion animal products was partially offset by the impact of COVID-19 and social distancing measures in certain EU markets and in Latin America, including Brazil, that resulted in decreased veterinary clinic traffic. Sales of livestock products declined 5% on a reported basis and grew 4% operationally. Sales of swine products grew as a result of expanding herd production in key accounts and increased biosecurity measures in the wake of African Swine Fever in China. The timing of seasonal vaccination protocols in key salmon markets and the recently launched parasiticide Alpha Flux were the primary drivers of growth in fish. Growth in our poultry portfolio was the result of increased sales of medicated feed additives and sales of biodevices. Sales of cattle products declined in the quarter due to the impact of COVID-19 in certain markets as well as the discontinuation of non-core products in Brazil.

INVESTMENTS IN GROWTH

Zoetis diversifies and grows its business through the introduction of new products, lifecycle innovations, business development initiatives, and entries into new markets and technologies. The company is increasingly focused on developing integrated solutions for pet owners, veterinarians and farmers that span the continuum of animal care - helping to predict, prevent, detect and treat diseases.

Since our last quarterly earnings announcement, Zoetis continued to bring leading products into new markets. In Brazil, Zoetis received approval for Vanguard B Oral, a vaccine that aids in preventing kennel cough in dogs, as well as Excenel RTU EZ (ceftiofur hydrochloride), an anti-infective that treats respiratory diseases in cattle and swine. Additionally, Fostera Gold PCV MH was approved in Australia. This vaccine provides livestock farmers with greater options and flexibility to reduce the clinical symptoms in pigs associated with porcine circovirus (PCV2) and Mycoplasma hyopneumoniae (M. hyo). Fostera Gold PCV Metastim was also approved in Australia to reduce the clinical symptoms associated with PCV2.

In addition to new product approvals and lifecycle innovations, Zoetis continues to support future growth through business development activities. In July, the company acquired Fish Vet Group as a strategic addition to its Pharmaq business, which develops and commercializes fish vaccines and offers services in vaccination and diagnostics for aquaculture. Adding Fish Vet Group grows the geographic reach and enhances the diagnostics expertise and testing services for fish farmers in major aquaculture markets.

Zoetis is raising and narrowing its full year 2020 guidance, which includes

Revenue between $6.300 billion and $6.475 billion

Reported diluted EPS between $3.14 and $3.32

Adjusted diluted EPS between $3.52 and $3.68

This guidance reflects foreign exchange rates as of mid-July. Additional details on guidance are included in the financial tables and will be discussed on the company's conference call this morning.

Use of Non-GAAP Financial Measures We use non-GAAP financial measures, such as adjusted net income, adjusted diluted earnings per share and operational results (which exclude the impact of foreign exchange), to assess and analyze our results and trends and to make financial and operational decisions. We believe these non-GAAP financial measures are also useful to investors

because they provide greater transparency regarding our operating performance. The non-GAAP financial measures included in this press release should not be considered alternatives to measurements required by GAAP, such as net income, operating income, and earnings per share, and should not be considered measures of liquidity. These non-GAAP financial measures are unlikely to be comparable with non-GAAP information provided by other companies. Reconciliation of non-GAAP financial measures and GAAP financial measures are included in the tables accompanying this press release and are posted on our website at www.zoetis.com.

(a) The condensed consolidated statements of income present the quarter and six months ended June 30, 2020 and June 30, 2019. Subsidiaries operating outside the United States are included for the second quarter ended May 31, 2020 and May 31, 2019.

(b) Non-GAAP adjusted net income and its components and non-GAAP adjusted diluted EPS are not, and should not be viewed as, substitutes for U.S. GAAP net income and its components and diluted EPS. Despite the importance of these measures to management in goal setting and performance measurement, non-GAAP adjusted net income and its components and non-GAAP adjusted diluted EPS are non-GAAP financial measures that have no standardized meaning prescribed by U.S. GAAP and, therefore, have limits in their usefulness to investors. Because of the non-standardized definitions, non-GAAP adjusted net income and its components and non-GAAP adjusted diluted EPS (unlike U.S. GAAP net income and its components and diluted EPS) may not be comparable to the calculation of similar measures of other companies. Non-GAAP adjusted net income and its components, and non-GAAP adjusted diluted EPS are presented solely to permit investors to more fully understand how management assesses performance.

ADJUSTED SELECTED COSTS, EXPENSES AND INCOME(a)

(millions of dollars)

(a) Adjusted cost of sales, adjusted selling, general, and administrative (SG A) expenses, adjusted research and development (R D) expenses, and adjusted net income attributable to Zoetis (non-GAAP financial measures) are defined as the corresponding reported U.S. GAAP income statement line items excluding purchase accounting adjustments, acquisition-related costs, and certain significant items. These adjusted income statement line item measures are not, and should not be viewed as, substitutes for the corresponding U.S. GAAP line items. The corresponding GAAP line items and reconciliations of reported to adjusted information are provided in Condensed Consolidated Statements of Income and Reconciliation of GAAP Reported to Non-GAAP Adjusted Information.

(b) Operational growth (a non-GAAP financial measure) is defined as growth excluding the impact of foreign exchange.

The guidance reflects the current view of the estimated full year impact of the COVID-19 outbreak, recessionary conditions in the global economy and foreign exchange rates as of mid-July 2020.

Reconciliations of 2020 reported guidance to 2020 adjusted guidance follows

(a) Operational growth (a non-GAAP financial measure) excludes the impact of foreign exchange.

(b) Adjusted net income and its components and adjusted diluted EPS are defined as reported U.S. GAAP net income and its components and reported diluted EPS excluding purchase accounting adjustments, acquisition-related costs and certain significant items. Adjusted cost of sales, adjusted SG A expenses, adjusted R D expenses, and adjusted interest expense and other (income) deductions-net are income statement line items prepared on the same basis, and, therefore, components of the overall adjusted income measure. Despite the importance of these measures to management in goal setting and performance measurement, adjusted net income and its components and adjusted diluted EPS are non-GAAP financial measures that have no standardized meaning prescribed by U.S. GAAP and, therefore, have limits in their usefulness to investors. Because of the non-standardized definitions, adjusted net income and its components and adjusted diluted EPS (unlike U.S. GAAP net income and its components and diluted EPS) may not be comparable to the calculation of similar measures of other companies. Adjusted net income and its components and adjusted diluted EPS are presented solely to permit investors to more fully understand how management assesses performance. Adjusted net income and its components and adjusted diluted EPS are not, and should not be viewed as, substitutes for U.S. GAAP net income and its components and diluted EPS.

(c) We do not provide a reconciliation of forward-looking non-GAAP adjusted net income operational growth to the most directly comparable U.S. GAAP reported financial measure because we are unable to calculate with reasonable certainty the foreign exchange impact of unusual gains and losses, acquisition-related expenses, potential future asset impairments and other certain significant items, without unreasonable effort. The foreign exchange impacts of these items are uncertain, depend on various factors, and could have a material impact on U.S. GAAP reported results for the guidance period.

(d) Primarily includes certain nonrecurring costs related to acquisitions and other charges.
