Kellogg's – breakfast cereals & snacks

Overview

Kellogg's began as the Battle Creek Toasted Corn Flake Company founded by W. K. Kellogg in Battle Creek, Michigan, and grew into a major multinational maker of breakfast cereals and related convenience foods. (britannica.com)

Corporate restructuring and current ownership

In 2023 the original Kellogg business was reorganized into two publicly traded companies — WK Kellogg (housing traditional cereal brands) and Kellanova (housing snacks and other non‑cereal breakfast brands). (investopedia.com)

Ferrero announced and completed the acquisition of WK Kellogg Co (the North American cereal portfolio) in 2025, making WK Kellogg a Ferrero subsidiary. (ferrero.com)

Mars, Incorporated completed the acquisition of Kellanova (the snack and many international cereal assets spun out of the original Kellogg business) in December 2025; those brands and operations now sit within Mars’ global snacking organization. (mars.com)

Manufacturing & geographic footprint

Kellogg’s branded products are manufactured in multiple countries worldwide (North America, Europe, Latin America, Asia and others) through the operating networks retained or transferred with each corporate split and subsequent acquisitions. The brand’s manufacturing and distribution footprint is therefore multinational and varies by specific product and market. (britannica.com)
