Control changed hands, takeover premiums sharpened, and foreign bidders kept testing the price of UK assets through May. The month’s largest UK-linked M&A stories moved across telecoms, energy, testing and certification, food ingredients, and ecommerce, but the same commercial logic ran through much of the activity: buyers wanted assets that could shorten the route to scale, infrastructure depth, customer access, or specialist capability.
By mid-May, UK M&A had reached $192bn for 2026, more than triple the level recorded at the same stage of 2025. Foreign takeovers accounted for $165bn of that figure, or 86% of UK M&A by value, according to LSEG data reported by Reuters. UK-targeted M&A also represented 10% of global deal announcements so far this year, the highest year-to-date share since 2015.
Those numbers sat behind a busy and uneven month. Vodafone moved to full control of the UK’s largest mobile operator. E.ON agreed a deal that could reshape household energy supply. EQT pressed Intertek with a higher private equity proposal. Ingredion approached Tate & Lyle with a possible cash offer. JD.com was reported to be considering a £2bn bid for The Very Group, extending the month’s takeover interest into UK retail infrastructure and consumer platforms.
Several of the largest stories remained conditional, possible, or reported rather than completed. That distinction matters in a market shaped by Takeover Code deadlines, regulatory approvals, shareholder pressure, and competing views of listed-company value. May’s deal flow still points to a clear pattern: when assets are difficult to replicate, buyers are willing to move before market confidence has fully returned.
Vodafone takes full control of VodafoneThree —
Vodafone agreed to buy CK Hutchison’s 49% stake in VodafoneThree for £4.3bn, taking full ownership of the UK’s largest mobile operator. The transaction follows the merger of Vodafone UK and Three UK, which created VodafoneThree as a private company owned 51% by Vodafone and 49% by CK Hutchison.
Full ownership gives Vodafone sole control of a mobile network with a stated £11bn investment plan and a target to reach 99% 5G standalone population coverage by 2030. With integration and network work already under way, the company is moving from joint-venture governance to direct command of one of the UK’s largest digital infrastructure platforms.
Vodafone chief executive Margherita Della Valle said: “I’m delighted that we will now have full ownership of VodafoneThree as we roll out one of Europe’s most advanced 5G networks, provide the UK’s best customer experience and drive long-term value for our shareholders.”
The transaction shows how capital-heavy telecoms combinations can move quickly from partnership into single-owner structures. Network integration, procurement, pricing, customer migration, and regulatory commitments all require sustained investment and fast operational decisions. In that setting, control can carry its own premium.
Intertek tests private equity appetite —
Intertek became May’s clearest public-market valuation test after EQT submitted a final, unsolicited, indicative, and conditional proposal to acquire the testing and inspection group. The proposal comprised £60 per share in cash, following earlier approaches at £51.50, £54, and £58 per share, which Intertek had rejected.
Reuters reported that Intertek was ready to recommend the £9.4bn proposal after investor pressure, and that the potential transaction would rank among the largest private equity takeovers in British history. Intertek said there could be no certainty that an offer would be made, leaving the company inside a live takeover process rather than a completed sale.
The attraction lies in a business model embedded across global supply chains. Intertek’s work in testing, inspection, certification, quality assurance, product safety, energy, infrastructure, and sustainability gives it exposure to services that companies cannot easily remove from procurement, compliance, or market-access processes.
A succession of higher proposals also placed the board under a familiar UK-listed-company strain. Management may argue for the value of an independent plan, while shareholders weigh the certainty of cash against the delivery risk of future earnings growth. In a market where international buyers can use sterling valuations and takeover premia to press their case, boards need more than a broad claim that the company is undervalued.
Tate & Lyle draws Ingredion approach —
Tate & Lyle confirmed that Ingredion had made a conditional proposal regarding a possible cash offer for the entire issued and to be issued ordinary share capital of the company. Under the proposal, Tate & Lyle shareholders would receive value of up to 615p per share, made up of 595p in cash and the right to receive permitted dividends of up to 20p per share.
The proposal followed a number of earlier approaches from Ingredion. Tate & Lyle said its board and Ingredion were in discussions, while adding that there could be no certainty an offer would be made or what the final terms might be. Under the Takeover Code, Ingredion has until 5pm on 11 June 2026 to announce a firm intention to make an offer or state that it does not intend to proceed, unless the deadline is extended.
Food ingredients have become a quieter but strategically important corner of consumer-sector dealmaking. Tate & Lyle has repositioned around speciality food and beverage ingredients, while large food manufacturers face private-label competition, changing consumer habits, margin pressure, and reformulation demand. Ingredion’s approach puts technical capability, formulation expertise, customer relationships, and global manufacturing exposure at the centre of the takeover logic.
The approach also widens May’s M&A pattern beyond regulated networks and listed services groups. Specialist supply-chain positions can command attention where scale improves research capability, pricing resilience, and access to multinational customers. In ingredients, value often sits behind the label rather than on the shelf.
E.ON agrees deal for OVO —
E.ON agreed to acquire OVO’s UK energy retail business, subject to regulatory approval, in a transaction that could create one of the country’s largest household energy suppliers. The purchase price was not disclosed, but OVO said the transaction includes its retail customers and the employees who support them.
Until completion, expected later this year, OVO and E.ON will continue to operate separately and customers will see no immediate changes. OVO also agreed to sell its Home Services business, covering boiler insurance and servicing, to Hometree, subject to regulatory approval.
The UK energy retail market has been reshaped by supplier failures, capital adequacy requirements, billing pressure, wholesale price volatility, and sustained political scrutiny over household bills. OVO said expectations on financial resilience and increasing regulatory oversight had changed how suppliers operate at scale, adding that the market’s next phase would favour greater scale and access to long-term capital.
E.ON’s agreement therefore reads as a scale transaction in a sector where customer numbers alone are no longer enough. Suppliers need capital for customer systems, flexible energy products, smart technology, and low-carbon services, while maintaining resilience through volatile commodity cycles. Larger balance sheets are becoming harder to separate from customer proposition, regulatory standing, and transition investment.
JD.com eyes The Very Group —
JD.com was reported to be evaluating a potential £2bn bid for The Very Group, the UK online shopping platform behind Very and Littlewoods. Reuters, citing Sky News, reported that the move would follow JD.com’s earlier UK efforts, including a failed takeover bid for Currys and its decision to walk away from talks to acquire Argos from Sainsbury’s.
The story remains less advanced than the agreed transactions and formal possible offers elsewhere in the month. Reuters said it could not immediately verify the report, while JD.com declined to comment on market speculation and The Very Group refused to comment.
Even at the reported-interest stage, the logic is rooted in platform value. The Very Group combines retail, data, consumer credit, logistics, and brand recognition, with annual revenue of £2.1bn and 4.2 million active customers, according to its own website. A large ecommerce operator seeking a stronger UK position would be buying more than sales volume; it would be buying infrastructure that is expensive and time-consuming to build organically.
JD.com’s reported interest extends the month’s deal activity into the operating systems of retail. UK consumer demand remains uneven, yet platforms with fulfilment capacity, payment relationships, customer data, and established brands can still attract international attention. Strategic value can rise when an asset solves a buyer’s market-entry problem, even when the consumer backdrop is difficult.
Bottom line —
May’s UK M&A stories were defined by control, scale, and valuation tension. Vodafone’s move for full ownership of VodafoneThree placed unified decision-making at the centre of capital-heavy telecoms investment. E.ON’s agreement for OVO reflected the financial resilience now required in energy retail. Intertek and Tate & Lyle showed how UK-listed companies can attract overseas or private capital when buyers see value beyond the public-market price.
Deal certainty varied across the month. E.ON and Vodafone announced agreed transactions, while Intertek and Tate & Lyle remained in possible-offer territory and JD.com’s interest in The Very Group was reported rather than confirmed. Those distinctions bring different approval, financing, shareholder, and execution risks, but the commercial pattern is consistent: hard-to-replicate assets are attracting buyers with the capital and patience to pursue them.
The UK’s appeal rests partly on familiar takeover rules, a deep pool of listed companies with international operations, and valuations that remain open to challenge. That creates a tougher environment for boards, particularly where shareholders are already questioning growth, margins, or capital allocation. Independence has to be defended through delivery, credible forecasts, and a convincing account of why the public market route can create more value than a cash premium.
Scale is also being pursued for different operational reasons. In telecoms, it supports network integration and investment. In energy, it supports resilience, customer technology, and transition products. In testing and assurance, it strengthens global service depth. In ingredients, it adds technical capability and customer reach. In ecommerce, it can shorten the route to local market access.
Four takeaways —
Control can be worth more than partnership when capital intensity, integration work, and regulatory commitments all point towards faster decision-making.
Public-market status offers limited defence when shareholders believe a cash premium is stronger than the standalone plan.
Scale needs a precise operating purpose, whether that is resilience, network investment, customer technology, pricing depth, or market entry.
Boards should keep bid-readiness current, from clean data rooms and realistic forecasts to decision rights, stakeholder mapping, and communications discipline.
The month’s largest UK-linked deal stories leave a practical benchmark for the rest of 2026. Buyers are concentrating on businesses that can deliver control, scarce capability, infrastructure depth, or customer access, while boards are being asked to prove that remaining independent offers more than patience and promise.
