Nvidia’s $40b deal for ARM dealt blow

Nvidia Corp's planned $40 billion acquisition of British chip designer ARM hit a major hurdle on Friday after a UK regulator found it could damage competition and weaken rivals, and required a further lengthy investigation.

The deal for Britain's most important technology company by the world's biggest maker of graphics and AI chips sparked a swift backlash from politicians, rivals and customers.

On Friday, Britain's competition regulator added to the pressure, saying the merged entity could reduce competition in markets around the world.
