Shares of Soho China, a real estate company run by a prominent power couple, fell by one-third on Monday after Blackstone Group walked away from its deal to buy the firm.
Soho China said in a joint filing late on Friday that Blackstone would not go through with its $3 billion bid for a controlling stake in the company, without giving a reason. Blackstone, the Wall Street investment giant, and Soho China declined to comment further on Monday.
The company is controlled by Zhang Xin and Pan Shiyi, a married couple who share the title of executive director. Mr. Pan, who is chairman, was one of the first Chinese entrepreneurs to use social media for public relations and has tens of millions of followers online. Ms. Zhang is well known in part for her role in a 2013 deal to buy a stake in the General Motors Building in Manhattan.
