Mars, the family-owned candy giant known for brands like M&M’s and Snickers, announced its acquisition of Cheez-It and Pringles maker Kellanova in a deal valued at nearly $36 billion. This marks the largest buyout in the packaged food industry to date.

Mars will pay $83.50 per share in an all-cash transaction, representing a 33% premium over Kellanova’s closing price on August 2, just before news of the potential deal broke. Following the announcement, Kellanova’s shares rose about 8% to $80.45, valuing the company at $28.58 billion on an equity basis.

This strategic acquisition comes at a time when sales growth in the U.S. packaged food sector is slowing, with budget-conscious consumers opting for cheaper, private-label products over more expensive branded items. The deal surpasses Mars’ previous $23 billion takeover of Wrigley in 2008 and will consolidate popular consumer brands under one roof. Mars’ portfolio includes Twix, Bounty, and Milky Way, while Kellanova’s offerings feature well-known snacks like Pop-Tarts, Rice Krispies Treats, and Eggo waffles.

Legal experts suggest that the acquisition is unlikely to face significant antitrust challenges due to the minimal overlap between the two companies’ product lines. Upon completion of the deal, expected in the first half of 2025, Kellanova will be integrated into Mars Snacking, led by Global President Andrew Clarke and based in Chicago.
