Vodafone buys out Three owner for £4.3 billion in UK mobile shake-up

Vodafone Group is moving to sole ownership of VodafoneThree, the UK’s largest mobile network, after agreeing to pay £4.3 billion to buy out its Hong Kong joint venture partner less than a year after the two companies merged.

Vodafone announced on Tuesday (5 May) that it will acquire CK Hutchison Group Telecom Holdings’ (CKHGT) entire 49% stake in VodafoneThree through a capital reduction and share cancellation agreement, funded from existing cash reserves.

The deal values VodafoneThree at an enterprise value of £13.85 billion, including debt, and will increase Vodafone’s pro forma net debt by 0.4 times adjusted earnings.

Completion is expected in the second half of 2026, subject to approval under the UK National Security and Investment Act.

VodafoneThree was formed on 31 May 2025 when Vodafone UK and Three UK merged, creating the UK’s largest mobile operator with over 28 million customers.

Vodafone held 51% of the combined business from day one, with CKHGT retaining the remaining 49%.

The original merger agreement included a put and call option framework allowing Vodafone to eventually acquire full control, but the buyout arrived less than 12 months after completion, marking a significantly faster consolidation than the market anticipated.

What full ownership means for UK customers

For consumers, the structural shift matters because it removes the joint governance constraints that come with a 49/49/51 joint venture.

Under the previous arrangement, Vodafone and CK Hutchison agreed a framework in which Vodafone held a casting vote on business plans and budgets but still required consent from CKHGT on a range of reserved matters.

With full ownership, Vodafone can accelerate strategic decisions without a co-shareholder veto on major commitments.

The most direct implication is the £11 billion network investment plan VodafoneThree committed to when the merger completed.

That figure represents a ten-year capital programme to build one of Europe’s most advanced standalone 5G networks, with £1.3 billion earmarked in capital expenditure for year one alone.

Vodafone has now stated it is more confident of delivering on that roadmap and of realising £700 million in annual cost and capital expenditure synergies by its 2030 financial year.

Faster network decisions under single ownership could bring forward 5G coverage upgrades for customers currently on both the legacy Vodafone and Three networks, which are still in the process of being integrated.

Vodafone Group Chief Executive Margherita Della Valle said in Tuesday’s announcement that the company will now roll out one of Europe’s most advanced 5G networks, provide the UK’s best customer experience and drive long-term value for shareholders.

Max Taylor will continue as CEO of VodafoneThree, supported by the existing leadership team.

CK Hutchison’s exit and what it signals

For CK Hutchison, the exit means a substantial return on its UK telecoms investment.

The South China Morning Post reported that the group said it intended to use the proceeds to strengthen its financial position, fund expansion and improve liquidity.

CKHGT’s Deputy Chairman Canning Fok confirmed the transaction monetises its investment at what he described as an attractive valuation, adding that CK Hutchison had been an early mover in 3G, launching Three UK in 2000.

VodafoneThree, now operating brands including Vodafone, Three, VOXI, SMARTY and Talkmobile, faces stiff competition from EE, which is owned by BT Group, and Virgin Media O2, itself a joint venture between Liberty Global and Telefónica.

Those two rivals have both benefited from the same scale logic that drove the Vodafone and Three merger, and the UK market will now run with three major network operators rather than four.

For customers, the competitive dynamics between these three scaled players will determine whether the promised 5G improvements translate into lower prices and better coverage, or simply into higher margins for the surviving networks.

Vodafone confirmed the deal will be funded without a fresh equity raise, drawing on the group’s existing liquidity.

Regulatory sign-off under the National Security and Investment Act is the principal remaining condition before completion, with Vodafone guiding investors to expect the transaction to close before the end of calendar year 2026.
