Japan’s SoftBank announced it will acquire data center investment firm DigitalBridge for $4 billion as part of its push into artificial intelligence.

The deal, approved unanimously by DigitalBridge’s board, values the company at $16 per share in cash, a 15% premium over its Dec. 26 closing price, and is expected to close in the second half of next year.

SoftBank CEO Masayoshi Son said the acquisition will support next-generation AI data centers and advance the company’s goal to become a leading “Artificial Super Intelligence” platform provider.

DigitalBridge CEO Marc Ganzi highlighted the deal as an opportunity to accelerate AI infrastructure development globally, CNBC has reported.

Following the announcement, DigitalBridge shares rose about 10%, and the company manages roughly $108 billion in assets.
