WK Kellogg is the second-largest cereal manufacturer in North America. Its cereal brands include Special K, Frosted Flakes, Raisin Bran, Froot Loops, Frosted Mini-Wheats, Kashi, Corn Flakes, Rice Krispies, Apple Jacks, and Bear Naked. The company was spun off from the former Kellogg business, now known as Kellanova, where the former firm's global snacks portfolio and international cereal brands are now housed. WK Kellogg, which began trading independently in October 2023, generates the bulk of its sales (about 88% of its fiscal 2024 base) in the US.
