Vodafone buys out CK Hutchison's 49% stake in VodafoneThree for £4.3bn, taking full control of the merged UK mobile network
Vodafone has announced it will purchase CK Hutchison's 49% stake in VodafoneThree for £4.3 billion, giving the UK-based mobile operator full ownership of the joint venture formed by the 2025 merger of Vodafone UK and Three UK. The deal gives Vodafone sole control over a combined network that emerged from approximately two years of regulatory scrutiny before the original merger was cleared. CK Hutchison described the consideration as providing an 'attractive' valuation. Vodafone framed the buyout as consistent with its wider operational simplification strategy, targeting approximately £700 million in annual capital expenditure (the ongoing investment a company makes in physical and infrastructure assets) by the 2030 financial year. Max Taylor will remain as chief executive of the combined business, and Vodafone will continue operating under the Three brand alongside its own. The transaction is a straightforward acquisition of a minority stake rather than a fresh merger, but its scale — £4.3bn for a 49% interest — makes it one of the largest UK telecoms transactions of 2026. The deal consolidates what was already a post-merger joint venture into a wholly owned subsidiary, completing the structural rationalisation of UK mobile infrastructure that began with the original Vodafone-Three combination.
Why this matters
A £4.3bn buyout of a joint-venture minority stake activates public M&A, corporate finance, and regulatory practice groups simultaneously. The original Vodafone-Three merger required CMA (Competition and Markets Authority) clearance and took roughly two years to navigate — counsel on this follow-on transaction will need to assess whether the stake acquisition itself triggers a fresh merger control filing or falls within existing approvals. The deal also raises questions about the ownership and licensing arrangements for the Three brand, and whether any regulatory conditions attached to the original merger need revisiting as Vodafone assumes sole control. The £700m capex target signals further infrastructure investment mandates ahead, with grid and spectrum agreements likely to require fresh legal work. At this deal size, Magic Circle and top Silver Circle telecoms practices will be best positioned.
On the Ground
On a transaction like this, a trainee would manage the CP (conditions precedent) checklist tracking regulatory and board approvals, draft board minutes for the Vodafone entity approving the acquisition, and assist with completion bible preparation once the stake transfer closes.

Question you might get
“The original Vodafone-Three merger required CMA clearance with conditions. Does Vodafone buying out CK Hutchison's stake require a fresh merger control filing, and what factors would you consider in advising the client?”
Full answer
Vodafone has agreed to buy CK Hutchison's 49% stake in VodafoneThree for £4.3 billion, gaining full control of the UK mobile network formed by last year's Vodafone-Three merger. This matters for law firms because consolidating a joint venture into a wholly owned subsidiary reopens questions about merger control compliance, brand licensing, and the conditions originally attached to the CMA-cleared deal. The wider trend is vertical integration in UK telecoms as operators seek to rationalise post-merger structures and drive infrastructure efficiencies. This suggests continued demand for regulatory, corporate, and telecoms-specialist legal work as Vodafone pursues its £700m annual capex target through 2030.
