Mars, owner of chocolates like M&Ms and Dove as well as pet brands like Pedigree, agreed to buy snack giant Kellanova, which makes Cheez-It and Pringles, for nearly $36 billion, according to a regulatory filing submitted Wednesday.

Mars will pay $83.50 per share, which represents a 33% premium over Kellanova’s closing price on Aug. 2. Kellanova stock soared earlier this month after the news was first reported, which is typical leading up to a deal.
