The owners of UK fiber network builder Nexfibre have sharply rejected the Competition and Markets Authority's (CMA) interim assessment of their planned takeover of rival Netomnia, calling the regulator's case “fundamentally flawed.” In a rare public rebuke, Telefónica, InfraVia, and Liberty Global said they would not offer any remedies to address competition concerns unless the CMA revises its underlying assumptions.
The statement marks an escalation in what is shaping up to be a contentious review of a deal that would consolidate two significant players in the UK's rapidly expanding full-fiber broadband market. The CMA's interim report, which typically outlines preliminary concerns before a final decision, appears to have struck a nerve with the companies involved.
What's behind the dispute?
Nexfibre is a joint venture backed by Spanish telecom giant Telefónica, French infrastructure investor InfraVia, and Liberty Global, the international cable and broadband group. The company is building a wholesale fiber network across the UK, aiming to compete with established players like Openreach and Virgin Media O2. Netomnia, meanwhile, is a smaller but fast-growing fiber network builder, and the proposed takeover would combine their rollout efforts.
The CMA's interim report is a preliminary stage in the regulator's merger review process. It sets out the agency's initial thinking on whether a deal could harm competition, often focusing on market share, the likelihood of future competition, and the impact on consumers. Companies typically respond with written submissions and may offer remedies—such as selling off parts of the business or making commitments about pricing—to address the regulator's concerns.
By refusing to offer remedies at this stage, the owners are signaling that they believe the CMA's analysis is so off-base that any concessions would be premature. They are effectively demanding that the regulator go back to the drawing board on its key assumptions before they will engage in the usual back-and-forth.
This is not the first time the CMA has faced pushback on a major deal. The regulator has been increasingly assertive in scrutinizing mergers, particularly in digital and infrastructure sectors. For instance, it recently moved to rein in Microsoft's bundling of Office and AI tools, and it has also probed Barclays' accounting for private credit swaps. The Netomnia case fits into this broader pattern of the CMA taking a hard line on deals it sees as potentially anti-competitive.
Why does this matter for investors?
For everyday investors, this dispute is more than just a regulatory spat. It has direct implications for the value of the companies involved and for the broader UK broadband market.
If the CMA ultimately blocks the deal or forces significant remedies, it could delay or derail Nexfibre's expansion plans. That could affect the returns that Telefónica, InfraVia, and Liberty Global expect from their investment. It could also slow the rollout of full-fiber broadband in the UK, which is a key part of the country's digital infrastructure strategy.
On the other hand, if the owners succeed in convincing the CMA to change its assumptions, the deal could proceed more smoothly, potentially boosting the value of the combined entity. Investors in these companies will be watching closely for any signals about the CMA's next steps.
The dispute also highlights the regulatory risk that comes with infrastructure investments. Building fiber networks is capital-intensive, and investors often rely on consolidation to achieve scale and profitability. When regulators push back, it can undermine those plans.
What happens next?
The CMA will now consider the responses to its interim report before issuing a final decision. The timeline for such reviews can vary, but typically the regulator aims to conclude within a few months. The owners' refusal to offer remedies could lengthen the process, as the CMA may need to reassess its analysis.
For now, the ball is in the CMA's court. The regulator could stick to its guns, revise its assumptions, or open a more detailed phase-two investigation. Each outcome would have different implications for the deal's fate.
Investors should note that this is a dynamic situation. Regulatory reviews are unpredictable, and the final outcome could differ significantly from the interim position. As with any merger, there is also the possibility that the parties walk away if the conditions become too onerous.
For those with exposure to the telecom or infrastructure sectors, this case is a reminder of the importance of regulatory developments. The CMA's approach to this deal could set a precedent for how it handles future consolidation in the UK's broadband market.
In the meantime, the owners' strong language suggests they are prepared to fight. Whether that leads to a negotiated settlement or a prolonged battle remains to be seen. Either way, the outcome will be closely watched by investors and industry observers alike.
