Kellogg Company

Kellanova, formerly known as the Kellogg Company, is an American multinational corporation, owned by Mars Inc., headquartered in Chicago, Illinois, and known for food manufacturing. The company became known as Kellanova on October 2, 2023, with the company's North American cereal operations spun off to form the WK Kellogg Co at the same time. The name combines "Kell" (from the Kellogg Company) with the Latin word nova, meaning "new". Kellanova produces and markets convenience foods and snack foods, including crackers, toaster pastries, and breakfast cereal. They market their products by several well-known brands including Kellogg's, Rice Krispies Treats, Pringles, Eggo, and Cheez-It. Outside of North America, Kellanova markets cereals such as corn flakes, Rice Krispies, Frosties, and Coco Pops. Kellanova's products are manufactured and marketed in over 180 countries. Kellanova's largest factory is at Trafford Park in Greater Manchester, United Kingdom, which is also the location of its UK headquarters. Other corporate office locations outside of Chicago include Battle Creek, Michigan; Dublin, Ireland (European Headquarters); Shanghai, China; and Santiago de Querétaro, Mexico. As Kellogg's, the company held a Royal Warrant from Queen Elizabeth II until her death in 2022. Kellogg's was restructured into two companies on October 2, 2023; WK Kellogg Co would manage the North American breakfast cereal division, while the previously existing company rebranded to "Kellanova", managing snack brands such as Pop-Tarts and Pringles alongside the international cereal division. The purpose of the split was to separate the convenience food, and international cereal products market, from the North American cereal market. "Kellogg's" itself became a brand name of both companies. Mars Inc., the owner of M&M's, Snickers, Doublemint, Life Savers, Starburst candy, and Sugus, entered into an agreement to acquire Kellanova for nearly $30 billion in August, 2024; The acquisition was completed on December 11, 2025.
