Dec 23, 2013

The Blackstone Group has sold a large portion of their SeaWorld Entertainment Inc. stock and is no longer the company's majority owner. Previously, Blackstone had owned about 63 percent of the stock and they've now cut that to 43 percent, though they still remain the largest stockholder. 18 million of Blackstone's shares were sold for $30 per share, for a total of $540 million. SeaWorld bought 1.5 million of the shares back.
