BRUSSELS (Reuters) -Nvidia's $54 billion bid for British chip designer ARM is expected to face an extended EU antitrust investigation after concessions offered last week failed to address competition concerns, three people familiar with the matter said.

An EU investigation would be the second setback for Nvidia coming two months after Britain's antitrust agency warned that the deal for the country's most important technology company could damage competition and weaken rivals.
