Neogen Corporation

Neogen Corporation is a global developer, manufacturer, and marketer of diverse products and services dedicated to food and animal safety. Headquartered in Lansing, Michigan, the company's mission is to be a leading provider of solutions that enhance food and animal well-being.

The company operates through two primary segments: Food Safety and Animal Safety. The Food Safety division offers diagnostic test kits and complementary products designed to detect dangerous and unintended substances in human food and animal feed, including foodborne pathogens, natural toxins, allergens, and drug residues. The Animal Safety segment provides a comprehensive range of veterinary instruments, pharmaceuticals, vaccines, diagnostic products, rodent and insect control solutions, disinfectants, and genomics testing services for livestock and companion animals. Neogen serves a broad customer base globally, including food processors, agricultural producers, veterinarians, and government agencies.

In recent leadership changes, Mike Nassif was appointed CEO and President, effective August 11, 2025, succeeding John Adent. Bryan Riggsbee also joined as Chief Financial Officer, effective November 3, 2025. A notable strategic move in March 2026 was the announcement of the sale of Neogen's global genomics business (GeneSeek) to Zoetis for $160 million, with the transaction expected to close by the end of Neogen's first half of fiscal 2027. This divestiture is part of a portfolio review, with net proceeds primarily intended for debt reduction. Neogen continues to position itself as a key player in global food security and animal well-being, aiming for leadership in food safety diagnostics.
