Giovanni Ferrero has expanded his family's company beyond brands like Nutella and built a global powerhouse—especially through big acquisitions in the U.S.

Private equity firm Cerberus Capital Management, which owns a stake in grocer Albertsons , and billionaire investor Dean Metropoulos teamed up in an unsuccessful bid for cereal maker WK Kellogg , according to three sources familiar with the matter.

Italian candy maker Ferrero has agreed to purchase U.S. cereal company WK Kellogg Co. in a $3.1 billion transaction, according to reports.

The Ferrero Group said Thursday it will buy WK Kellogg Co. in a deal valued $3.1 billion, expanding the Italian food giant's global reach. Kellogg, which was founded in Battle Creek, Michigan, in 1906, is known for brands including Corn Flakes, Froot Loops, Rice Krispies and Special K. Ferrero's brands include Nutella and Rocher chocolates.

Italian confectioner Ferrero, known for brands like Nutella and Kinder, is buying U.S. cereal company WK Kellogg in a deal valued at approximately $3.1 billion.

WK Kellogg Co. jumped nearly 30% on July 10 following the announcement from Italian food leader Ferrero regarding a $3.1 billion acquisition, inclusive of debt.
