Ferrero has been targeting the U.S. for acquisitions to grow geographically and expand by category. It bought Wells Enterprises, the maker of Blue Bunny and other ice-cream brands, and before that struck a $2.8 billion deal to acquire Nestlé’s U.S. chocolate business.

The Italian candy company Ferrero plans to buy the American cereal maker Kellogg for $3.1 billion, the companies announced Thursday. The deal would unite the makers of household brands including Nutella and Frosted Flakes.
