The $3.1 billion acquisition would combine Ferrero, which makes Tic Tacs and Nutella, with the producer of Frosted Flakes and Froot Loops.

WK Kellogg is Ferrero’s most substantial acquisition so far, with a market cap of roughly $1.5 billion and a portfolio of household-name cereals including Raisin Bran, Corn Flakes and Apple Jacks. Ferrero also bought Nestlé’s US business and Blue Bunny ice cream in recent years.

Italian confectioner Ferrero, known for brands like Nutella and Kinder, is buying the century-old U.S. cereal company WK Kellogg in a deal valued at approximately $3.1 billion. The Ferrero Group said Thursday it will pay $23 for each Kellogg share.
