Reuters had exclusively reported on Wednesday that both companies were set to win the EU regulatory antitrust approval for the deal.

Nvidia, known for its powerful gaming graphics chips, is looking to boost its data center and artificial intelligence business via the takeover, its biggest deal, to better compete with rival Intel.

U.S. authorities have already cleared the deal without conditions, while approval is still pending in China where Mellanox has major customers such as Alibaba and Baidu.
