Kellogg's (brand)

Overview

Kellogg's began in Battle Creek, Michigan, when W.K. Kellogg founded the Battle Creek Toasted Corn Flake Company in 1906; the business later became the Kellogg Company, a global maker of breakfast cereals and related snack foods. (britannica.com)

Corporate restructuring and ownership (2023–2025)

In 2023 the historic Kellogg Company split into two publicly traded businesses: WK Kellogg Co (the North American cereal business) and Kellanova (the snacks, international cereal and other non-cereal breakfast businesses). (britannica.com)

Subsequent transactions transferred ultimate ownership of those two businesses: Ferrero agreed to acquire and later completed the acquisition of WK Kellogg Co (the North American cereal operations), making WK Kellogg a Ferrero subsidiary. (ferrero.com)

Separately, Mars, Inc. agreed to acquire and completed acquisition of Kellanova (the former snacks and international cereal/food business), bringing Kellanova’s brands and operations into the Mars Snacking portfolio. (mars.com)

Manufacturing & geographic footprint

Kellogg’s brands are manufactured in multiple countries; the company historically operated production plants around the world and, after the 2023 split and subsequent acquisitions, the facilities and supply networks are now operated under the respective owners (Ferrero for WK Kellogg assets in North America; Mars for Kellanova assets and international operations).

Current brand ownership summary

As of early 2026 the Kellogg-origin brands and assets are controlled by two different ultimate owners depending on the business segment and geography: Ferrero controls the former WK Kellogg Co North American cereal business, while Mars, Inc. controls Kellanova’s snack and international cereal operations. This split means the historic Kellogg portfolio is now owned and operated by different global food groups, with manufacturing and distribution continuing across multiple countries under those new corporate owners.
