Mars has completed its acquisition of Kellanova, bringing together two of the world’s biggest branded food and snack businesses in a deal that reshapes competition across the US FMCG market and global supermarket supply chains.
The transaction was finalised in mid-January after receiving all regulatory approvals in December 2025. Kellanova shareholders approved the deal in November last year. Mars first announced the agreement in August 2024.
The acquisition adds Kellanova’s major brands to Mars Snacking, including Pringles, Cheez-It, Pop-Tarts, Rice Krispies Treats, RXBAR and Kellogg’s international cereal brands.
Mars already owns some of the world’s most recognised snack brands such as Snickers, M&M’s, Twix, Dove, Skittles, Extra, KIND and Nature’s Bakery.
Together, the combined business now controls a large share of global snacking categories across chocolate, savoury snacks, cereal bars and breakfast products.
The enlarged Mars Snacking division will operate across multiple fast-growing categories. Company executives say the integration strengthens Mars’ ability to scale innovation, expand distribution and increase long-term investment in product development and sustainability.
The acquisition also expands Mars’ Accelerator unit, which focuses on faster-growing health and performance brands. RXBAR, Nutri-Grain bars and Special K bars will now sit inside this division.
Mars is headquartered in McLean, Virginia, while Kellanova is based in Chicago. The combined group now employs more than 50,000 people within the snacking division alone and operates production and distribution sites across North America, Europe, Asia and emerging markets.
For supermarkets and retail buyers, the deal increases supplier concentration in branded snacks and breakfast categories. Large multinational retailers are expected to face stronger negotiating power from Mars as the group controls a wider portfolio of high-velocity shelf products.
The transaction also highlights continued consolidation across branded food manufacturing, as global FMCG groups look to strengthen scale and defend market share against private label growth.
Mars has not announced immediate changes to brand ownership structures or factory operations. Integration work is expected to continue throughout 2026 as systems, supply networks and commercial teams are aligned.
What Happens Next
Mars will now begin the operational integration of Kellanova into its global snacking business. Retail customers are expected to see gradual portfolio alignment, combined category strategies and potential distribution efficiencies during the year.
