ZTS vs CI Comparison

Zoetis sells anti-infectives, vaccines, parasiticides, diagnostics, and other health products for animals. The firm earns roughly 35% of total revenue from production animals (cattle, pigs, poultry, and so on), and nearly 65% from companion animal (dogs, horses, cats) products. Its us business is skewed even more heavily toward companion animals, while its international business is slightly skewed toward production animals. The firm has the largest market share in the industry and was previously Pfizer's animal health unit.

Cigna primarily provides pharmacy benefit management and health insurance services. Its PBM and specialty pharmacy services, which were greatly expanded by its 2018 merger with Express Scripts, are mostly sold to health insurance plans and employers. Its largest PBM contract is the Department of Defense, and it recently won a deal with top-tier insurer Centene. In health insurance and other benefits, Cigna mostly serves employers through self-funding arrangements, and the company operates mostly in the US with 18 million US medical members covered as of December 2023.
