MCLEAN, Va. & CHICAGO — Mars, Incorporated is set to close its acquisition of Kellanova on December 11, 2025, following unconditional approval from the European Commission. This decision marks the successful obtainment of all 28 required regulatory clearances for the merger, which was first announced in August 2024.
Upon closing, Kellanova’s major portfolio—including Pringles®, Cheez-It®, and Kellogg’s international cereal brands—will integrate with Mars Snacking, joining established brands such as SNICKERS® and M&M’S®. The combined snacking business is projected to generate approximately $36 billion in annual revenues. For the manufacturing sector, this merger consolidates a massive industrial footprint, with the new entity operating 80 global production facilities and serving over 145 markets.
Leadership from both organizations emphasized the strategic value of the union.
“We are excited to have received final regulatory approval for the pending acquisition of Kellanova,” said Poul Weihrauch, CEO and Office of the President of Mars, Incorporated. “Our focus now turns to welcoming Kellanova employees to Mars and creating an even more innovative global snacking business that delivers greater choice and quality to more consumers around the world.”
Andrew Clarke, Global President of Mars Snacking, highlighted the collaborative future of the entity. “Today marks an extraordinary milestone and the culmination of years of work for many of our Associates,” Clarke said. “We can’t wait to welcome Kellanova talent to Mars and create a shared, global snacking leader with a beloved range of brands.”
Steve Cahillane, Chairman, President and CEO of Kellanova, noted, “This combination will bring together two purpose-driven and principles-led companies. Serving as Kellanova’s Chairman, President and CEO has been a true honor, and I’m looking forward to seeing Kellanova people and brands thrive as part of Mars Snacking.”
Following the completion of the transaction, Kellanova’s common stock will be delisted from the New York Stock Exchange.
