Kellogg's

Kellogg's, a household name in the global food industry, has undergone a significant corporate transformation in recent years. Founded in 1906 by Will Keith Kellogg in Battle Creek, Michigan, the company originally revolutionized the breakfast category with the invention of Corn Flakes. For over a century, the Kellogg Company operated as a unified global entity.

In October 2023, the original Kellogg Company split into two independent, publicly traded companies: WK Kellogg Co, which focused on the North American cereal business, and Kellanova, which managed the global snacking portfolio, international cereal, and frozen foods. This separation was designed to allow each business to focus on its specific market dynamics—cereal in North America and high-growth snacks globally.

As of late 2025 and moving into 2026, the ownership of these entities has shifted through major acquisitions. Mars, Incorporated, the American confectionery and pet care giant, acquired Kellanova (the snacks-led business) in a deal valued at approximately $36 billion. Simultaneously, the Italian confectionery leader Ferrero Group acquired WK Kellogg Co (the North American cereal business) for roughly $3.1 billion. Today, while the iconic Kellogg's brand name remains on packaging worldwide, the ultimate ownership is divided between Mars (for snacks and international products) and Ferrero (for North American cereals), depending on the specific product and region.
