Quoted UK technology groups are rare. And this week, courtesy of SoftBank’s bid for ARM Holdings following the drop in sterling, which resulted in a 41% share price surge, they will become even more so. £24 billion seems a hefty price to pay for a computer chip designer, and judging by the 10% weekly drop in the Japanese telecoms giant’s share price, SoftBank holders agreed. But ‘smart’ chips for the ‘Internet of Things,’ seen as the next big wave in technology, are much in demand. The bid is the biggest ever Asian takeover of a UK firm.
