A proposed Japanese takeover of the British artificial intelligence company Graphcore is facing a national security review amid growing concern over foreign buyers targeting sensitive UK technology.
The inquiry has emerged in the wake of SoftBank, the Tokyo-based tech conglomerate that owns a majority stake in semiconductor company Arm, striking a deal for Graphcore.
It is understood the government review is the final hurdle to the tie-up being announced.
The deal is expected to be worth more than $500m (£400m), but substantially less than the $2.8bn the Bristol-based microchip company was valued at in 2020.
Multiple sources said the takeover was being scrutinised by the Business Department’s investment security unit (ISU).
ISU monitors investments in companies dealing in cutting-edge technology.
Hundreds of transactions are reviewed each year by the ISU, which was set up in 2022 under national security laws. The majority are cleared without restrictions.
Potential deals are often reviewed before investments are agreed and the Cabinet Office can in some circumstances apply conditions to takeovers.
Semiconductor and artificial intelligence technologies have faced increasing national security scrutiny in recent years because of their importance to defence and critical infrastructure.
One City lawyer said: “It would be shocking if the Government wasn’t looking at this given the nature of Graphcore’s business and the sensitivity that the UK has had about acquisitions for UK companies in this sector.”
SoftBank and Graphcore have not yet confirmed takeover talks.
Employees at the company are also believed to have been kept in the dark about developments.
However senior investors are understood to have been updated on the deal.
Graphcore, which develops semiconductors designed for artificial intelligence (AI) software, has been struggling to gain traction amid Nvidia dominating the market.
Nvidia’s graphics processors have proved critical for developing and powering AI software, such as OpenAI’s ChatGPT technology.
Demand for its chips has sent the US company’s valuation soaring to more than $3 trillion, as it briefly became the world’s most valuable business in June.
