Overview and origin
Kellogg's was founded in the United States by W.K. Kellogg and built as a leading breakfast cereal and convenience foods business with roots in Battle Creek, Michigan. (en.wikipedia.org)
Corporate structure and recent separations
In October 2023 the historic Kellogg Company separated into two independent businesses: Kellanova (global snacking, international cereals, noodles and certain frozen foods) and WK Kellogg Co (North American cereal business). The Kellogg's brand continued to appear on products but stewardship of operations and rights became split by region/business. (investor.kellanova.com)
Current ultimate ownership (as of Jan 18, 2026)
- Kellanova (which retained many Kellogg's international cereal and snacking brands) was acquired by Mars, Incorporated; the transaction closed and Kellanova became part of Mars' snacking business in December 2025. This makes Mars the ultimate owner for the portions of the Kellogg's portfolio managed under Kellanova (international cereals, snacks, and related brands). (mars.com)
- WK Kellogg Co (the former North American cereal company that managed Kellogg's cereal brands in the U.S., Canada and the Caribbean) was acquired by Ferrero Group in 2025; Ferrero completed that transaction in September 2025 and is the ultimate owner of the North American cereal business.

Manufacturing footprint
Kellogg's-branded products are manufactured in multiple countries across North America, Europe, Asia and beyond. Kellanova/WK Kellogg historically and currently operate and invest in manufacturing facilities worldwide (examples include large cereal plants in the UK, North America and new/expanded snack lines in Asia), so production is distributed across multiple countries rather than originating from a single country.
