EW vs ZTS Comparison

Spun off from Baxter International in 2000, Edwards Lifesciences designs, manufactures, and markets a range of medical devices and equipment for advanced stages of structural heart disease. It has established itself as a leader across key products, including surgical tissue heart valves, transcatheter aortic valves, and transcatheter mitral and tricuspid valve technologies. The firm derives about 60% of its total sales from outside the US.

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.
