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.

History
On June 21, 2022, Kellogg's announced a plan to spin off its three cereal, snacks, and plant-based food divisions into separate companies. The North American cereal and plant-based food spin-off companies were to keep Battle Creek as their headquarters and the new snack and international cereal company would be based in Chicago. The successor company, known as Global Snacking Co. temporarily, represented 80 percent or $11.4 billion of Kellogg's sales. Sixty percent of Global Snacking's business was snacks, and nearly half of the company's business was in the United States. The cereal business, temporarily called North America Cereal Co., was to be the second-largest American cereal company and the largest in Canada and the Caribbean, with 5 of the top 11 brands and $2.4 billion in annual sales. Plant-based foods, representing $340 million in annual sales, were to be called "Plant Co." and could potentially be sold.
In January 2023, Kellogg's shelved its plans to spin off its plant food business and retained it as part of Global Snacking Co. On March 15, 2023, Kellogg's announced that the North America Cereal Co. branch would be named WK Kellogg Co and the Global Snacking Co. branch would be called Kellanova. The split was structured with Kellanova as the surviving company, using the ticker symbol "K" on the NYSE. The WK Kellogg Co took the NYSE stock symbol "KLG". The split was completed on October 2, 2023.
On August 14, 2024, Mars Inc. agreed to purchase Kellanova for nearly $30 billion. The purchase, originally planned to close in the first half of 2025, was approved by the Federal Trade Commission (FTC) in the US but it was delayed to December 11, 2025, due to the European Commission not approving the deal until December 8, 2025.
The acquisition was completed on 11 December 2025, with Kellanova being integrated into Mars. Kellanova CEO Steve Cahillane stepped down from the company following the acquisition and the company was delisted from the New York Stock Exchange.
