Europe says yes: Mars wins final approval for $35.9bn Kellanova deal, but is global snacking about to change?

Mars Incorporated, a family-owned global heavyweight in snacking, pet care, and food, is officially set to acquire Kellanova, the New York Stock Exchange–listed leader in global snacking and international cereals, following an unconditional green light from the European Commission. This move, announced on December 8, 2025, clears the last significant regulatory barrier for the $35.9 billion all-cash acquisition, positioning Mars to close the deal by December 11 and unite two of the world’s most recognizable snacking portfolios.

The deal, which will see Kellanova’s celebrated brands like Pringles, Cheez-It, Pop-Tarts, Rice Krispies Treats, RXBAR, and Kellogg’s global cereal lineup join Mars’ powerhouse stable—including SNICKERS, M&M’S, TWIX, SKITTLES, EXTRA, and KIND—creates a consumer products juggernaut with approximately $36 billion in annual snacking revenues and nine brands each topping $1 billion in yearly sales. Mars Snacking, now poised to become a global leader in both scale and breadth, will be anchored in Chicago and operate in more than 145 markets, supported by over 50,000 employees and a sprawling production and retail network.

What made EU regulators approve the Mars–Kellanova merger without conditions?

The European Commission subjected the transaction to an in-depth review, focusing particularly on whether Mars’ acquisition of Kellanova would enable it to wield greater bargaining power over retailers—potentially leading to higher prices or restricted consumer choice. Investigators weighed the possibility that adding Kellanova’s brands to the Mars portfolio could give the combined entity undue leverage in negotiations, especially in countries where both are dominant players.

However, after extensive scrutiny, the Commission concluded that Kellanova’s core products, such as Pringles and Kellogg’s cereals, would not significantly increase Mars’ influence in retail talks. The rationale was multifaceted: Kellanova’s brands are mainly long-shelf-life, impulse, or infrequently purchased products, reducing their strategic importance in everyday shopping baskets. In addition, the Commission found little evidence that consumers are so brand-loyal to Mars and Kellanova combined that they would switch supermarkets en masse if both portfolios were unavailable in their primary store—a “basket effect” that might have forced retailers to accept higher prices.

Another key finding was the lack of any systemic risk that the combined snack powerhouse could extract higher prices through portfolio bundling, given that most products compete in distinct categories and that consumers typically do not substitute across these brands. While Mars and Kellanova already enjoy market strength in various product segments across several European markets, the evidence gathered did not indicate that the merger would alter this dynamic in a way that would harm competition or consumer welfare.

How big is Mars now—and what’s changing for snack lovers and investors?

With the acquisition, Mars Snacking cements its status as a $36 billion global player in the consumer goods sector, spanning everything from candy bars and rice to pet food and now international cereals and savory snacks. The combined network will include 80 production facilities and more than 170 owned retail outlets like Hotel Chocolat and M&M’S World, serving millions of snack enthusiasts around the globe. Mars Snacking’s new, broader portfolio features nine individual brands with over $1 billion in annual revenue, a statistic few consumer firms can match.

For investors, the financials are equally hefty. Mars’ purchase price of $83.50 per share in cash represented a 44% premium to Kellanova’s 30-day average share price and a 33% premium to its previous 52-week high, equating to a multiple of 16.4 times Kellanova’s latest twelve-month adjusted EBITDA. The Kellanova shareholder base had already approved the transaction back in November, setting the stage for a rare megamerger in the consumer food space.

Kellanova’s stock, which will be delisted following the close, enjoyed a sharp rally after the deal was announced, reflecting strong buy-in from institutional holders attracted by the immediate premium and the clarity on regulatory risks. While Mars is not publicly listed, the deal’s closure eliminates uncertainty and could spur strategic reviews among competitors such as Mondelez International, Nestlé, and General Mills, which now face an even more formidable rival in the snacking and convenience food landscape.

What are executives and market observers saying about the merger’s strategic logic?

According to Mars Incorporated’s CEO Poul Weihrauch, the final regulatory approval marks the beginning of an ambitious new era, with an emphasis on integrating Kellanova’s talent and portfolio to drive even greater innovation and consumer choice. Andrew Clarke, Global President of Mars Snacking, described the deal as the culmination of years of effort and the start of a journey to build a “shared, global snacking leader.” Steve Cahillane, Kellanova’s outgoing CEO, underscored the cultural fit and “purpose-driven” alignment between the two companies, voicing confidence that Kellanova’s people and brands would thrive as part of the Mars ecosystem.

Industry analysts suggest that Mars’ “better together” narrative is well-founded, given the complementary nature of the two businesses and the limited overlap in their main product categories. The merger not only increases scale and bargaining power with suppliers and distributors, but also broadens the group’s innovation pipeline in emerging snacking trends, from plant-based ingredients to health-forward treats.

What happens next for the snacking industry and consumers?

With all 28 necessary regulatory approvals secured and closing expected by December 11, the Mars–Kellanova transaction now stands as one of the defining consumer M&A deals of the decade. The European Commission’s decision signals a pragmatic approach to food sector consolidation—prioritizing evidence of actual market impact over theoretical risks.

For snack lovers, the immediate effect will be an even wider range of familiar brands under one corporate umbrella, with the promise of expanded innovation and potentially stronger global distribution. For retailers, the outcome is relief: no single supplier will gain outsized leverage to dictate prices. And for competitors, Mars’ expanded reach and resources raise the bar for future competition and deal-making across the sector.

How are investors and analysts interpreting the Mars–Kellanova merger’s impact on future snack sector consolidation and dealmaking trends?

Institutional sentiment around the Mars–Kellanova deal remains largely positive. Kellanova’s share price reflected optimism about deal closure and the premium on offer, with a wave of buying activity from long-only asset managers following the initial announcement. There is little sign of regulatory overhang in Europe, as the process wrapped up without conditions, and the U.S. Federal Trade Commission was also seen as unlikely to block the deal given the global context and category differences.

Market watchers will now look to see whether Mars uses its new scale to drive international expansion, boost margins through supply chain synergies, or double down on health and wellness trends. Analysts expect that other major consumer companies will explore consolidation or innovation partnerships to keep pace, while Mars could seek bolt-on acquisitions in emerging snacking niches.

What does the final approval of the Mars–Kellanova merger ultimately mean for the future shape, scale and competitive direction of the global snacking industry?

Mars’ $35.9 billion buyout of Kellanova, capped by unconditional EU approval, redefines the competitive landscape of global snacks and cereals. The merger creates a consumer behemoth with reach, diversity, and muscle—though, for now, shoppers are unlikely to feel a pinch at the checkout. The message from Brussels: size alone is not a sin if market evidence shows consumers and retailers still hold the cards.
