The deal that changed the shape of Mars
Mars acquired Kellanova for $36 billion, according to ConfectioneryNews, making it the largest acquisition in the company's history. Kellanova brought Pringles, Pop-Tarts, and Cheez-It into the Mars portfolio, significantly expanding Mars beyond confectionery and into global snacking staples. That matters because snacking categories outside of chocolate have shown stronger and more resilient growth, and Mars had been watching that gap for some time.
The Kellanova deal is not a one-off. It is the latest step in a pattern that goes back at least to 2008, when Mars acquired Wrigley, moving the company into chewing gum and related formats. Trü Frü followed in 2022, adding better-for-you snacks and giving Mars a foothold in a fast-growing segment where health-conscious shoppers are trading up. Each deal has moved Mars further from its heritage in chocolate bars and closer to a diversified snacking platform.
Why the timing makes sense
The confectionery category faces real structural pressure. Cocoa prices have been volatile, and that volatility is not going away. Brands that depend heavily on cocoa for their margin structure are more exposed than those with a diversified ingredient base. Kellanova's portfolio, built largely around grain-based and savoury snacks, is a partial hedge against that exposure.
The GLP-1 drug trend adds a second layer of uncertainty. As appetite-suppressing drugs become more widely used, some analysts expect demand for high-calorie indulgent snacking to soften over time. Mars has not publicly named GLP-1 as a driver of its M&A strategy, but building a broader snacking platform reduces the risk of any single category being disproportionately affected.
What the numbers say
The $36 billion Kellanova price tag is the headline figure, but the post-deal investment story is also significant. Mars has committed £190 million to upgrade its Slough factory in the UK, a project explicitly tied to the post-Kellanova growth strategy, per ConfectioneryNews. That investment runs from 2023 through 2028 and follows a separate €1 billion investment across European Union markets that Mars announced before it, according to Food Business News. Capital is flowing into the manufacturing base, not just the deal book, which suggests Mars is treating integration and capacity expansion as a single programme rather than sequential steps.
Partnership deals as a lower-risk M&A complement
Not every strategic move requires a full acquisition. Mars is running a limited pilot with Planet A Foods, a German start-up, testing a cocoa-free chocolate alternative made from a fermented sunflower-seed ingredient called ChoViva, per FoodNavigator. The Balisto Trail Mix using ChoViva is being sold exclusively at German retailer Rewe from April to October 2026. If the pilot performs, Mars gains optionality to scale or acquire. If it does not, the exposure is contained. Planet A Foods already has contracts with Barry Callebaut and Nestlé, so Mars is entering a competitive supply relationship, not an exclusive one, and that competitive tension is worth watching.
This kind of structured pilot partnership is increasingly common in Big Food M&A thinking. Rather than buying a start-up outright at a peak valuation, companies test commercial viability first. You can expect more of these arrangements from Mars as it probes ingredients and formats that could reduce its cocoa dependence over time.
How this compares to what competitors are doing
Ferrero acquired the Wonka brand rights from Nestlé in 2018 and has spent years developing a consumer-led refresh, now launching 10 seasonal and limited-edition products in partnership with Netflix, per ConfectioneryNews. Ferrero also acquired WK Kellogg Co, according to ConfectioneryNews, signalling a parallel move into cereal and breakfast snacking. Nestlé, by contrast, has been selling assets, including parts of its coffee and waters businesses.
Unilever is pursuing a $40 billion merger of its Foods business with McCormick, but the deal has triggered investor exits and a sharp share-price decline, per The Sunday Times and ConfectioneryNews. The market reaction to Unilever's deal is a useful contrast to how Mars is perceived. As a private company, Mars does not face the same real-time shareholder scrutiny, which gives it more room to act on long investment horizons without quarterly pressure to justify each move.
What to watch next
The Slough investment runs to 2028, so integration progress there will be a useful signal of whether Mars can absorb the Kellanova scale while modernising its legacy manufacturing. The Planet A Foods pilot ends in October 2026, and any signal of a broader rollout, an extended contract, or a stake change would indicate Mars is moving toward structural cocoa risk reduction rather than just testing the waters.
Watch also for any further bolt-on deals in better-for-you snacking or functional formats. The Trü Frü acquisition in 2022 and the RXBar Protein Energy Bites innovation signal that Mars sees protein and better-for-you positioning as growth territory. An acquisition in that space, or a minority stake in a functional snacking brand, would fit the established pattern and would be the logical next move in a portfolio that is deliberately broadening its reach.
