Bill Gates’ Cascade Investment LLC will take control of Four Seasons Hotels and Resorts by acquiring about half of Saudi Arabian Prince Alwaleed bin Talal’s stake in the company for $2.21 billion, the hotel operator said on Wednesday.

Cascade will purchase 23.8 percent of Prince Alwaleed’s stake to own 71.3 percent of Four Seasons, valuing the hotel chain at $10 billion on an enterprise basis.

Prince Alwaleed, through investment vehicle Kingdom Holding Co., will continue to own the remaining stake, Four Seasons said.

The billionaire prince is one of Saudi Arabia’s top businessmen and is known for his bets on Citigroup and other top western companies.
