Kellogg's – Breakfast cereals & snacks

Brand origin and product category

Kellogg's began in the United States (originating from the Battle Creek Toasted Corn Flake Company founded by Will Keith "W.K." Kellogg) and is best known for ready-to-eat breakfast cereals and adjacent packaged breakfast/snack products. The brand covers a wide range of SKUs including corn flakes, flake/multi-grain cereals, cereal bars, toaster pastries and snack items.

Manufacturing footprint

Kellogg's products are manufactured in multiple countries around the world. Production spans plants in North America, Europe, Asia and other regions — the brand operates a global manufacturing and supply network rather than a single-country production model.

Corporate history and ownership (key dates)

• 1906: W.K. Kellogg founded the Battle Creek Toasted Corn Flake Company (brand origin). The business later became Kellogg Company.
• October 2, 2023: The former Kellogg Company completed a separation creating two independent public companies — Kellanova (global snacking, international cereals, noodles and certain frozen businesses) and WK Kellogg Co (North American cereal business). The Kellogg's brand continued to be used across both entities in various markets.
• September 26, 2025: Ferrero Group completed its acquisition of WK Kellogg Co, bringing the North American cereal portfolio (brands such as Frosted Flakes, Froot Loops, Rice Krispies, etc., as managed by WK Kellogg Co) under Ferrero ownership.
• December 11, 2025: Mars, Incorporated completed its acquisition of Kellanova, bringing Kellanova's portfolio (Pringles, Cheez-It, Pop-Tarts, and Kellogg's international cereal brands among others) into Mars Snacking.

Current ownership structure (as of January 18, 2026)

Kellogg's as a global consumer-facing brand no longer sits under a single public parent company. Instead, the historic Kellogg portfolio is split operationally and by region: north American cereal trademarks and operations formerly run by WK Kellogg Co are a Ferrero subsidiary; Kellanova's international cereal and global snacking portfolio (which also used the Kellogg's brand in many markets) is now part of Mars Snacking. This means responsibility for production, marketing and regional licensing of "Kellogg's" labeled products is handled by those respective owners in their operating territories.

Practical implications

• For consumers: Packaging and product lines labeled "Kellogg's" can be produced by different corporate owners depending on the product type and market (North America vs. international snacking/cereals).
• For supply-chain, regulatory, and sourcing queries: manufacturing country and site will vary by SKU and market; verify production origin on specific product packaging or supplier declarations for precise country-of-origin details.

Summary

Kellogg's is an American-born breakfast-cereal and snack brand with a global manufacturing footprint. Since the corporate separation in 2023 and subsequent acquisitions in 2025, the brand's assets are ultimately controlled by two major food companies: Ferrero Group (North American cereal business via acquisition of WK Kellogg Co) and Mars, Incorporated (global snacking and international cereal portfolio via acquisition of Kellanova).
