Zoetis (ZTS) 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 spun out of Pfizer in 2013 and is now the largest standalone animal health company in the world. Zoetis sells its products directly to veterinarians, livestock producers, and farm operators, earning revenue through product sales rather than subscriptions. It operates in over 100 countries, with the United States and Europe making up the majority of revenue. Its moat comes from a large portfolio of patented drugs, deep relationships with vets, and the high cost of getting new animal medicines approved — all of which make it hard for competitors to take market share. The main growth driver is the rising number of pet owners willing to spend more on their animals' health, though a key risk is patent expirations on top products like Apoquel and Cytopoint, which could invite generic competition.
