Unilever–McCormick Merger Hits a Snag: UK Watchdog Says $44.8 Billion Food Deal Could Hurt Competition

One of the biggest food deals in history has hit its first serious roadblock. Britain’s competition watchdog said on Wednesday, 11 November 2026, that the planned $44.8 billion merger between Unilever’s foods business and American spice maker McCormick could harm competition in the UK — and the two companies now have one week to fix the problem or face a long, detailed investigation.

The Unilever–McCormick merger would join some of the most familiar names on supermarket shelves: Hellmann’s mayonnaise and Knorr stock cubes on one side, and Frank’s RedHot sauce, French’s mustard and Schwartz spices on the other. But the UK’s Competition and Markets Authority (CMA) says that in two small but important corners of the supermarket — dry recipe mixes and dry sauces — the combined company would be far too powerful.

What happened on 11 November

The CMA published its Phase 1 decision on the deal on Wednesday morning. After a two-month review that began on 16 September 2026, the regulator concluded that McCormick’s purchase of most of Unilever’s global foods business gives rise to a “realistic prospect of a substantial lessening of competition” in the UK.

In plain language, that means the watchdog believes the deal could leave shoppers with less choice and higher prices in the affected product categories. It is not a decision to block the deal. It is a warning: offer a fix, or the deal goes to a much deeper Phase 2 investigation that could take months and could end with the merger being blocked or changed.

The companies have until 18 November 2026 to offer remedies — formally called “undertakings in lieu of reference”. If they offer nothing, or if the CMA decides their proposal is not good enough, the watchdog will refer the transaction for a full Phase 2 probe.

A Unilever spokesman described a possible Phase 2 referral as an “expected step” in the regulatory process, suggesting the company had prepared for this outcome.

Why the watchdog is worried

The CMA’s concerns are narrow but specific. It looked at three product categories supplied to UK retailers: dry ingredient mixes, dry sauces, and mustard.

In dry ingredient mixes — the sachets used to make dishes such as chilli con carne at home — and in dry sauces such as parsley sauce, the regulator found that McCormick and Unilever are the two biggest branded suppliers in the country. Put them together, and the merged company would be “by far” the largest supplier in both categories.

The watchdog also found that the two companies compete closely with each other today. Rival brands exist — Nestlé’s Maggi in mixes and Premier Foods’ Bisto in sauces — but the CMA concluded they only provide a “limited competitive constraint” on the combined business. In other words, they are not strong enough to keep the merged giant honest on price and quality.

There was one piece of good news for the companies. On mustard, the CMA found “no realistic prospect of competition concerns”, clearing that part of the deal.

The CMA also confirmed it has the power to review the deal because the UK turnover of both McCormick and Unilever Foods is more than £100 million each.

The deal in numbers

The merger was announced in March 2026 and is one of the largest food deals ever attempted. Here are the key figures:

• $44.8 billion (£34 billion): the value placed on Unilever’s foods business in the transaction.
• $15.7 billion: the amount McCormick agreed to pay in cash, with the rest paid in shares.
• About $65 billion: the reported value of the combined food company once the deal closes, according to Reuters.
• 55.1%: the share of the enlarged company that Unilever shareholders would own.
• 35%: the share McCormick’s existing investors would hold. Unilever itself would keep a 9.9% stake.
• Mid-2027: when the deal is expected to complete, if regulators approve it.
• 18 November 2026: the deadline for the companies to offer remedies to the CMA.

The transaction is the second-largest food deal in history, according to Reuters. It cleared the antitrust process in the United States in October 2026, but the UK review was always expected to be a harder test because both companies are so strong in British supermarkets.

Unilever Foods generated €3.1 billion (about $3.4 billion) in turnover in the third quarter of 2026, with underlying sales growth of just 0.1% — a reminder that the foods business has been growing slowly, which is part of the reason Unilever wants to sell it.

What brands are involved

The deal covers most of Unilever’s global foods business. The best-known names changing hands include:

• Hellmann’s — the world’s biggest mayonnaise brand, a staple in fridges across the UK, Europe and the Americas.
• Knorr — stock cubes, soups and sauces sold in more than 90 countries.
• Colman’s — the mustard and sauce brand Unilever has already put up for sale in an attempt to calm competition concerns.

On the McCormick side, the deal brings together:

• Frank’s RedHot — the hot sauce that has become a fixture in American kitchens and is growing fast internationally.
• French’s — the classic yellow mustard brand.
• Schwartz — the herbs and spices brand that is McCormick’s main name in the UK, and the direct rival to Knorr and Colman’s in the categories the CMA is worried about.

Together, the combined company would be a global flavour giant, selling sauces, seasonings and condiments in almost every country in the world.

Why Unilever is selling its food business

Unilever’s chief executive, Fernando Fernandez, has been reshaping the company since taking charge. His plan is to focus Unilever on the parts of the business that grow fastest and earn the highest profits: beauty, wellbeing, personal care and home care — products such as Dove soap, Vaseline and Persil washing powder.

Foods, by contrast, has been a slower business. Sauces and soups are mature products in many markets, and growth has been hard to find. Selling most of the foods division to McCormick lets Unilever concentrate on its stronger brands while its shareholders keep a majority stake in the new combined food company.

The strategy has already hit one obstacle. Just weeks before the CMA decision, the Dutch competition regulator blocked Unilever’s planned sale of the Unox brand — the Dutch soup and sausage brand — to Zwanenberg. It is a sign that regulators in several countries are looking closely at food deals.

Why McCormick wants the deal

For McCormick, based in Maryland in the United States, the deal is a chance to become a truly global food company. McCormick is already the world’s largest spice company, but most of its sales come from North America. Buying Unilever’s foods business would give it famous brands, factories and distribution networks in Europe, Asia and Latin America almost overnight.

The combined group would be led by McCormick’s chief executive, Brendan Foley, and its chief financial officer, Marcos Gabriel.

Investors reacted cautiously to the CMA’s decision. McCormick’s shares fell 2.4% in London trading by 9am on Wednesday, while Unilever’s shares were unchanged. The small fall suggests investors had expected some trouble from the UK regulator, but the risk of a long delay is real.

What happens next

The next milestone is 18 November — just seven days after the CMA’s decision. By that date, the companies must offer remedies that satisfy the watchdog. The most likely options are selling off one of the overlapping brands or product lines — for example, part of the dry mixes or dry sauces business — so that competition in those categories is protected.

Unilever has already moved in that direction by deciding to sell the Colman’s brand and its assets, although the company has not said exactly which products would be included in such a sale.

If the CMA accepts the remedies, the deal can move forward in the UK. If it does not, the merger goes to a Phase 2 investigation — a deeper review that typically takes around six months, involves detailed hearings, and can end with the deal being approved, approved with conditions, or blocked entirely.

Completion of the whole transaction is conditional on clearance from competition authorities, including the CMA. A long UK investigation would not necessarily kill the deal, but it would delay it and could force the companies to sell more assets than they planned.

What it means for shoppers

For now, nothing changes on supermarket shelves. The deal has not closed, and the brands involved will keep competing as before. But the CMA’s decision matters for shoppers in two ways.

First, it shows the watchdog is watching food prices closely. Dry mixes and dry sauces are cheap, everyday items, but they are bought by millions of households. If one company controlled most of the market, it could raise prices or cut back on promotions with little fear of losing customers to rivals.

Second, the case is a test of how far regulators will go to protect competition in the food industry. Food mergers have often been waved through in the past. The CMA’s firm stance suggests that even in small product categories, a deal that creates a dominant supplier will face serious scrutiny.

What it means for investors

For investors, the CMA decision adds uncertainty to a deal that was already complex. The merger is the biggest in both companies’ histories, and it involves dozens of brands, factories and regulators across many countries.

The good news for the companies is that the CMA’s concerns are limited to two narrow categories. A targeted sale — of a brand or a product line — could solve the problem without damaging the logic of the whole deal. The bad news is that Phase 2 investigations are slow and unpredictable, and any delay pushes back the cost savings and growth the companies have promised shareholders.

Analysts will now be watching the 18 November deadline closely. A quick, credible remedy offer would be the best outcome for both companies. A referral to Phase 2 would be a setback, but not a fatal one — many large mergers have survived Phase 2, sometimes with bigger asset sales than first planned.

Frequently asked questions

What is the Unilever–McCormick merger?

McCormick, the world’s biggest spice company, agreed in March 2026 to buy most of Unilever’s global foods business — including Hellmann’s mayonnaise and Knorr — in a deal valuing the business at $44.8 billion. The combined company would be one of the largest food businesses in the world.

Why has the UK watchdog objected?

The Competition and Markets Authority (CMA) says the deal could substantially lessen competition in the UK market for dry ingredient mixes and dry sauces sold to retailers. The merged company would be by far the largest supplier in both categories, and rivals such as Maggi and Bisto are not strong enough to keep it in check.

Is the deal blocked?

No. The CMA has not blocked the deal. It has given the companies until 18 November 2026 to offer remedies. Only if no acceptable remedy is offered will the deal be referred for an in-depth Phase 2 investigation.

What is a Phase 2 investigation?

Phase 2 is the CMA’s deeper merger review. A panel of experts examines the deal in detail over several months, takes evidence from the companies, customers and competitors, and can approve the deal, approve it with conditions such as selling assets, or block it.

Which brands are involved?

From Unilever: Hellmann’s, Knorr and Colman’s. From McCormick: Frank’s RedHot, French’s mustard and Schwartz. The combined business would also include many smaller local brands around the world.

When will the deal complete?

The companies expect the deal to complete by mid-2027, subject to regulatory approvals. A Phase 2 investigation in the UK could push that date back.

Does the CMA decision affect other countries?

No, the CMA’s decision applies only to the UK market. The deal has already cleared US antitrust review. Other countries’ regulators are carrying out their own reviews.

Conclusion

The CMA’s decision on 11 November is a setback for the Unilever–McCormick merger, but it is not the end of the road. The watchdog’s concerns are focused on two narrow supermarket categories, and the companies have a clear path to fix them: offer to sell off the overlapping business by 18 November.

What the decision does show is that regulators are no longer willing to wave through giant food deals without a fight — even when the products involved are as ordinary as a sachet of chilli mix or a packet of parsley sauce. For Unilever and McCormick, the next seven days will decide whether their $44.8 billion deal moves forward smoothly or heads into months of detailed investigation. For shoppers, the CMA’s intervention is a reminder that competition rules apply to the weekly shop just as much as to big technology or energy deals.
