UK Business Secretary Jonathan Reynolds has confirmed that he would have vetoed the proposed $40 billion (approximately R730 billion) acquisition of chip designer Arm by American technology giant Nvidia had he been in a position to make the decision at the time. Speaking during a media interview in June 2026, the Secretary reaffirmed his stance on the protection of critical national technology assets.
Regulatory Hurdles And Market Concerns
The takeover attempt, which was officially abandoned by the companies in February 2022, faced intense scrutiny from global regulators, including the UK’s Competition and Markets Authority. Official records indicate that authorities in the United States, the European Union, and the United Kingdom harboured significant concerns that allowing the merger would grant Nvidia excessive control over semiconductor technology, which is essential for the global smartphone and computing markets.
“I would have blocked it. I think it was right that it was blocked, and I would have taken that decision,” Reynolds said during his interview.
National Sovereignty Over Tech Assets
The collapse of the deal is widely regarded as a watershed moment for the United Kingdom’s approach to foreign investment in sensitive sectors. Arm’s chip designs serve as the foundation for the overwhelming majority of the world’s mobile devices, making its independence a matter of significant economic and national security interest.
This case spurred the implementation of more stringent investment and national security legislation, designed to better protect domestic firms from foreign takeovers that could threaten strategic interests. The government is expected to continue prioritising these safeguards as it navigates the balance between attracting global investment and maintaining control over the architectural foundations of modern technology.
