The UK is considering blocking a takeover of Arm Ltd by Nvidia Corp due to potential risks to national security, people familiar with the discussions said.
Nvidia, the biggest US chip company by market capitalization, announced in September last year a US$40 billion deal to acquire Arm from Japan’s Softbank Group Corp, as part of a push to spread its reach in the surging market for semiconductors.
British Secretary of State for Digital, Culture, Media and Sport Oliver Dowden in April asked the Competition and Markets Authority (CMA) to prepare a report on whether the deal could be deemed anti-competitive, along with a summary of any national security concerns raised by third parties.
The assessment, delivered late last month, contains worrying implications for national security and the UK is currently inclined to reject the takeover, a person familiar with government discussions said.
The UK is likely to conduct a deeper review into the merger due to national security issues, a separate person said.
No final decision has been taken and the UK could still approve the deal alongside certain conditions, the people added.
Dowden is set to decide on whether the merger needs further examination by competition authorities.
“We continue to work through the regulatory process with the UK government,” an Nvidia spokesperson said in a statement. “We look forward to their questions and expect to resolve any issues they may have.”
Nvidia shares were little changed on Tuesday, while Softbank shares fell 1.5 percent in Tokyo yesterday.
A spokesperson for the CMA declined to comment.
Arm owns the most widely used set of standards and designs in the chip industry. Its technology is at the heart of most of the world’s smartphones and is finding an increasing role in computing, including in server machinery that runs corporate and government systems.
The Cambridge-based company has acted as a neutral party which sells chip blueprints and licenses its standards to a wide range of major technology companies, many of whom are fierce competitors.
Ownership by Softbank, which acquired it in 2016 and which does not overlap with Arm’s customers, has preserved that neutrality.
It is unclear how Arm’s change from Japanese to US ownership would affect UK national security, but since Softbank’s acquisition, semiconductor technology has become a new focus for politicians.
Newport Wafer Fab Ltd, based in Wales, is currently under review by the British government after it agreed to be sold to a Chinese manufacturer for about ￡63 million (US$88 million).
Arm’s position at the heart of the chip industry means the deal has already raised concerns, because Nvidia directly competes with Arm’s customers like Qualcomm Inc, Intel Corp and Advanced Micro Devices Inc.
Others have publicly endorsed the change of ownership.
Some of Nvidia’s rivals have said they would be ready to invest in Arm to help it continue independently, if Nvidia is not allowed to buy it. The deal is also subject to regulatory approvals in China, the EU and the US.
Nvidia has pledged to maintain Arm’s independence if the takeover is completed and invest heavily to increase its reach, but any takeover deal is likely to attach conditions, such as maintaining the about 3,000 UK employees and keeping the company’s headquarters in Cambridge, England.
Nvidia chief executive Jensen Huang (黃仁勳) has said he remains confident that regulators would approve the company’s acquisition of Arm.
If the deal is blocked by regulators, Softbank is likely to pursue an initial public offering (IPO) of Arm, two people familiar with the matter said.
In a blog post last month, Arm chief executive Simon Segars said: “The combination of Arm and Nvidia is a better outcome than an IPO.”
RECYCLE: Taiwan would aid manufacturers in refining rare earths from discarded appliances, which would fit the nation’s circular economy goals, minister Kung said Taiwan would work with the US and Japan on a proposed cooperation initiative in response to Beijing’s newly announced rare earth export curbs, Minister of Economic Affairs Kung Ming-hsin (龔明鑫) said yesterday. China last week announced new restrictions requiring companies to obtain export licenses if their products contain more than 0.1 percent of Chinese-origin rare earths by value. US Secretary of the Treasury Scott Bessent on Wednesday responded by saying that Beijing was “unreliable” in its rare earths exports, adding that the US would “neither be commanded, nor controlled” by China, several media outlets reported. Japanese Minister of Finance Katsunobu Kato yesterday also
Jensen Huang (黃仁勳), founder and CEO of US-based artificial intelligence chip designer Nvidia Corp and Taiwan Semiconductor Manufacturing Co (TSMC, 台積電) on Friday celebrated the first Nvidia Blackwell wafer produced on US soil. Huang visited TSMC’s advanced wafer fab in the US state of Arizona and joined the Taiwanese chipmaker’s executives to witness the efforts to “build the infrastructure that powers the world’s AI factories, right here in America,” Nvidia said in a statement. At the event, Huang joined Y.L. Wang (王英郎), vice president of operations at TSMC, in signing their names on the Blackwell wafer to
‘DRAMATIC AND POSITIVE’: AI growth would be better than it previously forecast and would stay robust even if the Chinese market became inaccessible for customers, it said Taiwan Semiconductor Manufacturing Co (TSMC, 台積電) yesterday raised its full-year revenue growth outlook after posting record profit for last quarter, despite growing market concern about an artificial intelligence (AI) bubble. The company said it expects revenue to expand about 35 percent year-on-year, driven mainly by faster-than-expected demand for leading-edge chips for AI applications. The world’s biggest contract chipmaker in July projected that revenue this year would expand about 30 percent in US dollar terms. The company also slightly hiked its capital expenditure for this year to US$40 billion to US$42 billion, compared with US$38 billion to US$42 billion it set previously. “AI demand actually
RARE EARTHS: The call between the US Treasury Secretary and his Chinese counterpart came as Washington sought to rally G7 partners in response to China’s export controls China and the US on Saturday agreed to conduct another round of trade negotiations in the coming week, as the world’s two biggest economies seek to avoid another damaging tit-for-tat tariff battle. Beijing last week announced sweeping controls on the critical rare earths industry, prompting US President Donald Trump to threaten 100 percent tariffs on imports from China in retaliation. Trump had also threatened to cancel his expected meeting with Chinese President Xi Jinping (習近平) in South Korea later this month on the sidelines of the APEC summit. In the latest indication of efforts to resolve their dispute, Chinese state media reported that
