Mars, maker of M&M's and Snickers, to buy Cheez-It owner Kellanova for nearly $30 billion

M&M's maker Mars is buying Kellanova, the maker of Cheez-Its and Pop-Tarts for nearly $30 billion, vastly expanding the number of household-name brands under one roof.

Kellanova was created last year when the Kellogg Co. split into three companies. Kellanova sells many of the former company's most profitable brands, including Pringles, Eggo, Town House, MorningStar Farms and Rice Krispies Treats. It had net sales of more than $13 billion last year and has approximately 23,000 employees.

Mars Inc. said Wednesday (August 14) that it will pay $83.50 per share in cash. The company put the total value of the transaction at $35.9 billion, including debt.

It is the biggest deal in the sector since J.M. Smucker bought Hostess for $5.6 billion last year, and among the largest of 2024, coming in second to Exxon Mobil's $60 billion acquistion of Pioneer Natural Resources.

Mars' purchase of Kellanova is expected to close in the first half of next year. Once it's complete, Kellanova will become part of Mars Snacking. Corporate headquarters will remain in Chicago.

Mars, headquartered in McLean, Virginia, is one of the largest privately held companies in the U.S.

“The Kellanova brands significantly expand our snacking platform, allowing us to even more effectively meet consumer needs and drive profitable business growth,” Andrew Clarke, global president of Mars Snacking, said in a statement.

The other company formed in the Kellogg split, WK Kellogg Co., retained cereal brands like Raisin Bran, Frosted Flakes and Froot Loops, which have struggled with slowing sales in recent years. It is not involved in the deal.

The acquisition would expand Mars’ reach into the salty snack category. The company owns brands like Combos and Uncle Ben’s, but it’s primarily known for its chocolates, candies and pet food. Mars makes M&M’s, Lifesavers, Juicy Fruit gum and Skittles as well as Pedigree and Royal Canin pet foods, among other products.

Sales of some of those products, like gum, have sputtered in recent years as snacking habits shift. The deal helps Mars expand into areas of growth.

It also may help Kellanova at a time when rising prices are squeezing consumers and putting many companies under pressure to put a cap on prices. Economists say that many consumers appear to be returning to pre-pandemic norms, when most companies felt they couldn’t raise prices very much without losing business.

Mars got its start in 1911, when founder Frank Mars started making and selling butter cream candy from his home in Tacoma, Washington. The company moved to Chicago in 1929 and introduced the Snickers bar the following year.

Mars has steadily grown through acquisitions. It entered the pet food business in 1935 with the purchase of a U.K. dog food brand and bought the Dove ice cream brand in 1986. In 2008, it purchased the Wrigley chewing gum business for $23 billion.

Shares of Kellanova rose nearly 8% before the opening bell Wednesday.
