Elanco is a global animal health company that develops, manufactures and distributes pharmaceutical products, vaccines, feed additives and other therapeutics for pets and farm animals. The company generates revenue by selling prescription and non-prescription parasiticides (such as Advantage and Seresto), as well as antibiotics, ionophores, probiotics and vaccines to veterinarians, distributors, retailers and producers through both traditional and e-commerce channels. The business derives revenue from its diverse product portfolio across pet health and farm animal segments, though it faces ongoing competitive pressures from generic substitutes, regulatory restrictions on antibiotic use in livestock, and shifting consumer demand toward antibiotic-free animal products.
