Zoetis (ZOE.DE) Stock Analysis & Winston Score
Zoetis makes medicines and vaccines for animals. Its products treat pets like dogs and cats, as well as farm animals like cattle, pigs, and chickens. The company was originally part of Pfizer and is now the largest standalone animal health company in the world. Zoetis earns money by selling prescription drugs, vaccines, and diagnostic tools directly to veterinarians, livestock producers, and farm operators. It operates in more than 100 countries, with the United States and Europe as its biggest markets. Its moat comes from strong brand loyalty among vets, a large sales force, and the high cost of developing new animal drugs — advantages that are difficult for smaller rivals to copy. The key growth driver is the rising "humanization" of pets, which pushes owners to spend more on animal healthcare, though the company also faces risk from generic competition as some of its top products lose patent protection.
