LONDON (Reuters) -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.
Struck in September last year, 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.
