The United Kingdom’s decision to approve the $19 billion merger between Vodafone and Three UK marks a significant shift in the country’s antitrust strategy, reflecting a growing emphasis on economic growth and infrastructure investment over prioritizing lower consumer prices.
Regulatory Approval and Economic Priorities
The Competition and Markets Authority (CMA) cleared the Vodafone-Three merger after accepting arguments that improved network capabilities would bolster competition and benefit the UK economy. This approval aligns with the government’s call for regulators to consider growth as a priority.
This move contrasts with the CMA’s controversial 2023 decision to block Microsoft’s $69 billion acquisition of Activision Blizzard, citing concerns over competition in cloud gaming. That earlier rejection highlighted the CMA’s hesitance to accept “behavioral remedies”—commitments on operations to maintain market fairness.
However, in the Vodafone-Three case, the CMA adopted a different approach, delegating oversight of pricing and investment commitments to telecoms regulator Ofcom. This signals a departure from its traditionally rigid stance on behavioral remedies.
Government and Industry Reactions
UK Prime Minister Keir Starmer reinforced the government’s pro-growth stance during an October 2024 forum, urging regulators to adopt a growth-focused perspective. Vodafone’s CEO, Margherita Della Valle, echoed this sentiment, emphasizing the importance of connectivity for the country’s economic ambitions.
“Good connectivity is critical to so many parts of our lives and is central to the UK’s economic growth ambitions,” Della Valle stated, highlighting Britain’s lagging mobile network speeds. According to analytics group OpenSignal, the UK ranks 22nd out of 25 European countries for 5G availability and download speeds.
Legal and Market Implications
Competition lawyer Alex Haffner described the CMA’s decision as pragmatic, noting its reliance on behavioral remedies rather than structural ones—such as forcing the creation of new competitors—which have historically dominated European network mergers.
“Over the past decade, four-to-three mobile network mergers in Europe required significant structural remedies. This decision shows a willingness to explore alternatives,” Haffner said.
Operators argue that structural remedies kept prices low but stifled investment, limiting the potential benefits of market consolidation. The CMA’s evolving approach could encourage more mergers in the UK market, particularly if behavioral remedies prove sufficient to address competition concerns.
Monitoring and Challenges Ahead
Despite the approval, the CMA and Ofcom face the challenge of monitoring compliance with the merger’s terms, potentially for up to eight years. Competition lawyer Tom Smith noted that while the decision demonstrates flexibility, the reliance on behavioral remedies will likely remain rare.
“Allowing behavioral remedies commits regulators to extensive oversight and ongoing adjustments to investment plans,”Smith said. “It may be less controversial than the Microsoft case, but it’s far from simple.”
A Broader Shift in Antitrust Approach
The Vodafone-Three merger reflects a broader shift in the CMA’s regulatory philosophy under Sarah Cardell’s leadership, which appears more open to mergers that promote growth. Analysts suggest this pragmatic stance could encourage consolidation across other industries.
For instance, the CMA blocked a merger between Sainsbury’s and Asda in 2019, citing concerns over reduced competition in the supermarket sector. With its evolving approach, similar deals might now receive a different outcome, provided they align with economic growth objectives.
The Vodafone-Three merger approval marks a turning point in UK antitrust regulation, balancing competition with the need for investment-driven economic development.
