BRUSSELS - EU antitrust regulators are set to open a full-scale investigation into Nvidia's $54 bln bid for British chip designer Arm because concessions it offered are not sufficient to address competition concerns, people familiar with the matter said.

The world's biggest maker of graphics and AI chips offered behavioural remedies, the people said. Such remedies usually refer to pledges by companies to take measures aimed at preserving competition.

The EU competition enforcer has not sought feedback from rivals and customers on the concessions, indicating that they were not sufficient, the people said.
