> Zoetis made four substantive modifications to existing risk disclosures while maintaining 43 unchanged risks and adding or removing no risk categories overall. The modifications focused on antibiotic restrictions in animal agriculture, product concentration dependencies, customer financial pressures, and e-commerce operational capabilities. This approach reflects refinement of existing risk narratives rather than a fundamental shift in the company's risk profile.

## Modified: Restrictions and bans on the use of and/or consumer preferences regarding antibacterials in food-producing animals may become more prevalent.

**Key changes:**

- Reworded sentence: "In some countries, this issue has led to government restrictions and bans on the use of specific antibacterials in some food-producing animals."
- Reworded sentence: "Our total revenue attributable to antibacterials for livestock was approximately $950 million for the year ended December 31, 2024."

**Prior (2024):**

The issue of the potential transfer of increased antibacterial resistance in bacteria from food-producing animals to human pathogens, and the causality of that transfer, continue to be the subject of global scientific and regulatory discussion. Antibacterials refer to small molecules that can be used to treat or prevent bacterial infections and are a sub-categorization of the products that make up our anti-infectives and medicated feed additives portfolios. In some countries, this issue has led to government restrictions and bans on the use of specific antibacterials in some food-producing animals, regardless of the route of administration (in feed or injectable). These restrictions are more prevalent in countries where animal protein is plentiful and governments are willing to take action even when there is scientific uncertainty. Our total revenue attributable to antibacterials for livestock was less than $950 million for the year ended December 31, 2023. For example, regulations regarding antibiotic usage in animals have been introduced in certain markets, including the U.S., the EU, China, France, Germany, and Vietnam. In addition, certain jurisdictions like Italy have implemented the use of electronic prescriptions, which has caused more disciplined use of antibiotics and decreased the demand for our antibacterial products. Also, in certain markets, there has been an increase in consumer preference towards proteins produced without the use of antibiotics. We cannot predict whether antibacterial resistance concerns will result in additional restrictions or bans, expanded regulations, public pressure to discontinue or reduce use of antibacterials in food-producing animals or increased consumer preference for antibiotic-free protein, any of which could materially adversely affect our operating results and financial condition.

The issue of the potential transfer of increased antibacterial resistance in bacteria from food-producing animals to human pathogens, and the causality of that transfer, continue to be the subject of global scientific and regulatory discussion. In some countries, this issue has led to government restrictions and bans on the use of specific antibacterials in some food-producing animals. These restrictions are more prevalent in countries where animal protein is plentiful and governments are willing to take action even when there is scientific uncertainty. Our total revenue attributable to antibacterials for livestock was approximately $950 million for the year ended December 31, 2024. As a result of the divestiture of our medicated feed additive product portfolio, certain water soluble products and related assets, we anticipate our total revenues attributable to antibacterials for livestock will decrease. For example, regulations regarding antibiotic usage in animals have been introduced in several markets, including the U.S., the EU, the U.K., China and Vietnam. In addition, certain jurisdictions like Italy have implemented the use of electronic prescriptions, which has caused more disciplined use of antibiotics and decreased the demand for our antibacterial products. Also, in certain markets, there has been an increase in consumer preference towards proteins produced without the use of antibiotics.

## Modified: Our results of operations are dependent upon the success of our top-selling products.

**Key changes:**

- Reworded sentence: "If any of our top-selling products or product lines experience issues, such as loss of patent protection, material product liability litigation, new or unexpected side effects (or an increased frequency of serious, expected adverse events), manufacturing or supply chain disruptions, regulatory proceedings or enforcement, labeling changes, public regulatory communications, negative publicity or social media attention, changes to veterinarian or customer preferences, and/or disruptive innovations or the introduction of competing and/or more effective products, our revenues could be negatively impacted, perhaps significantly."

**Prior (2024):**

If any of our top-selling products or product lines experience issues, such as loss of patent protection, material product liability litigation, new or unexpected side effects, manufacturing or supply chain disruptions, regulatory proceedings, labeling changes, negative publicity, changes to veterinarian or customer preferences, and/or disruptive innovations or the introduction of competing and/or more effective products, our revenues could be negatively impacted, perhaps significantly. For example, our five top-selling products and product lines, Simparica/Simparica Trio, Apoquel/Apoquel Chewable, Cytopoint, Revolution/Revolution Plus/Stronghold and ceftiofur line, contributed approximately 37% of our revenue in 2023, and any issues with these top-selling products and product lines would have a more significant impact to our results of operations.

**Current (2025):**

If any of our top-selling products or product lines experience issues, such as loss of patent protection, material product liability litigation, new or unexpected side effects (or an increased frequency of serious, expected adverse events), manufacturing or supply chain disruptions, regulatory proceedings or enforcement, labeling changes, public regulatory communications, negative publicity or social media attention, changes to veterinarian or customer preferences, and/or disruptive innovations or the introduction of competing and/or more effective products, our revenues could be negatively impacted, perhaps significantly. For example, our five top-selling products and product lines, Simparica/Simparica Trio, Apoquel/Apoquel Chewable, Cytopoint, Librela and our ceftiofur line, contributed approximately 41% of our revenue in 2024, and certain issues with these top-selling products and product lines could have a more significant impact to our results of operations.

## Modified: Our business is subject to risk based on customer exposure to rising costs and reduced customer income.

**Key changes:**

- Reworded sentence: "Concerns about the financial resources of pet owners could cause veterinarians to alter their treatment recommendation in favor of lower-cost alternatives to our products."

**Prior (2024):**

Feed, fuel and transportation and other key costs for livestock producers may increase or animal protein prices or sales may decrease. Either of these trends could cause deterioration in the financial condition of our livestock product customers, potentially inhibiting their ability to purchase our products or pay us for products delivered. Our livestock product customers may offset rising costs by reducing spending on our products, including by switching to lower-cost alternatives to our products. In addition, concerns about the financial resources of pet owners also could cause veterinarians to alter their treatment recommendations in favor of lower-cost alternatives to our products. These shifts could result in a decrease in sales of our companion animal products, especially in developed countries where there is a higher rate of pet ownership.
