Summary

  • Vodafone acquired CK Hutchison’s 49% interest on 30 July 2026, becoming VodafoneThree’s sole owner; the CMA says Vodafone’s existing undertakings did not change.
  • VodafoneThree’s first progress report records completed early network milestones, yet redacted counts and coverage cells limit what outsiders can independently test.

The change in the share register is not the change to watch

Vodafone paid £4.3 billion (€4.9 billion) for CK Hutchison Group Telecom Holdings Limited’s 49% stake, financing the transaction from existing cash, according to Vodafone. It now owns all of VodafoneThree. That is a significant change in corporate control. It is not, by itself, evidence that the obligations attached to the merger have been renegotiated.

The Competition and Markets Authority (CMA) made the distinction explicit when it published the buyout details. CK Hutchison no longer holds shares, interests or rights in VodafoneThree and no longer controls it. Clause 2.3 tied CK Hutchison’s obligations to its period of control, so CK Hutchison ceased to be bound. The CMA also says no obligation owed by Vodafone changed and that the Final Undertakings remain in full effect.

The ownership transition therefore narrows the parties responsible for delivery. It does not erase the public benchmark. For customers, wholesale partners and investors, the practical question is whether progress remains observable when the joint venture becomes a wholly owned subsidiary of one of its former parents.

What Year 1 can—and cannot—show

On 29 September, the CMA published VodafoneThree’s first annual progress report. The company had exceeded an informal Year 1 site target: the report shows 103.26% against a 100% reference. That percentage needs careful handling. The report labels the Year 1 figure informal and removes the actual site totals from its non-confidential version. It is evidence of reported progress against an early reference point, not proof that the binding network commitment has already been fulfilled.

Two operational milestones are more concrete. By the end of the first reporting year, VodafoneThree had activated 2x20 MHz of 1800 MHz spectrum at almost 15,000 sites across the Three UK grid; the activation was complete. Early Years MOCN—multi-operator core network sharing—had reached more than 10,000 sites, and that activation was also complete. Those statements establish scale and completion of the specified early actions. They do not reveal site-by-site performance or establish how much each action improved service in a particular place.

The coverage table illustrates the limits. The report defines its Year 1 rows as combined networks: the pre-existing, non-upgraded network plus the upgraded network. It lists 4G population coverage of 99.32% for combined Vodafone and 99.73% for combined Three. Most regional, 5G and geographic cells are removed. The figures cannot be read as a clean before-and-after experiment, and the missing cells prevent readers from reconstructing a complete national picture.

This is not proof of underperformance. It is a constraint on public verification. A report can be sufficient for a monitoring trustee and regulators while remaining too incomplete for customers or market participants to reproduce the assessment independently.

Three clocks, three constituencies

The remedies have different time horizons. The CMA describes an eight-year joint network plan. Selected mobile tariffs are capped for three years, while wholesale services are offered on preset prices and terms for three years. Those shorter protections matter to retail customers and mobile virtual network operators during the early integration period; the longer network commitment addresses investment and network delivery.

Vodafone’s own announcement adds a separate set of company expectations: an £11 billion investment plan and £700 million of annual cost and capital-expenditure synergies by FY30. These are management claims about the economics of full ownership. They are not the CMA’s compliance measures. A cost saving can be real without proving better coverage; a regulatory milestone can be met without proving that projected synergies will arrive. Combining them into one score would hide the question each measure answers.

Sources and limits

The CMA case page records the ownership change and legal effect; its Year 1 report supplies the progress figures and redactions. Vodafone’s release is the source for transaction value, funding and its own financial targets. The CMA’s merger guidance describes the commitment periods. The available record does not demonstrate a service failure caused by the buyout, nor does it permit a full independent engineering audit of the first-year results.
