Mars has finalised its acquisition of Kellanova, consolidating two iconic businesses and positioning Mars Snacking as a formidable force in the market.


Andrew Clarke, global president of Mars Snacking, heralded the acquisition as a transformative moment, highlighting the combined legacy of both companies in pioneering new product categories.


“Today marks a transformative moment, and I’m excited to welcome Kellanova to Mars,” Clarke said. “Together, we are uniquely positioned to bring consumers more of the brands they love while advancing our sustainability commitments and investing for the long term.”


The newly formed Mars Snacking division now boasts an impressive portfolio that includes Kellanova’s billion-dollar brands alongside Mars’ existing powerhouses such as Snickers, M&M’s and Twix.


The companies say this alignment will create synergies that will enhance product offerings and drive innovation in snacking.


The acquisition, which was first announced in August 2024, has successfully navigated the regulatory landscape, receiving necessary approvals from Kellanova shareholders and regulatory bodies, including the European Commission and the US Federal Trade Commission.


As of 8 December 2025, all regulatory hurdles have been cleared, allowing Mars to integrate Kellanova’s extensive brand portfolio into its operations.
