Zoetis Inc was incorporated in Delaware in July 2012. It is engaged in the discovery, development, manufacture and commercialization of animal health medicines and vaccines, with a focus on both livestock and companion animals. It has a diversified business, marketing products across eight core species: cattle, swine, poultry, sheep and fish (collectively, livestock) and dogs, cats and horses (collectively, companion animals); and within five product categories: anti-infectives, vaccines, parasiticides, medicated feed additives and other pharmaceuticals. The Company organizes and operates its business in two geographic regions: the United States (U.S.) and International. Within each of these operating segments, it offers a diversified product portfolio for both livestock and companion animal customers. The Company directly markets its products in approximately 45 countries across North America, Europe, Africa, Asia, Australia and South America. The Company sells its livestock products directly to a diverse set of livestock producers, including beef and dairy farmers as well as pork, poultry and aquaculture operations, and to veterinarians, third-party veterinary distributors and retail outlets that typically then sell the products to livestock producers. It sells the companion animal products to veterinarians or to third-party veterinary distributors that typically then sell its products to veterinarians, and in each case veterinarians then typically sell its products to pet owners. Its primary competitors include animal health medicines and vaccines companies such as Merck Animal Health, the animal health division of Merck & Co., Inc.; Merial, the animal health division of Sanofi S.A.; Elanco, the animal health division of Eli Lilly and Company; Bayer Animal Health, the animal health division of Bayer AG; and Boehringer Ingelheim Animal Health, the animal health division of Boehringer Ingelheim GmbH.
