SeaWorld Entertainment’s Antarctica: Empire of the Penguin attraction, opening today at the company’s namesake theme park in Orlando, features 50-foot glaciers, 2,500 glass icicles and up-close encounters with 230 penguins, dusted daily with 6,000 pounds of snow. “It is the coolest attraction in the world,” President and Chief Executive Officer Jim Atchison said in an interview. “You kind of check out of the rest of SeaWorld and find yourself in Antarctica.” To Atchison, it’s also an example of how private-equity firms, often criticized for dismantling the companies they buy, can jumpstart a business like SeaWorld. Blackstone Group LP bought the company, which owns 11 parks in five states, for $2.3 billion from Anheuser-Busch InBev NV in December 2009. As a small part of the world’s largest brewer, SeaWorld was starved. Atchison, who took Orlando, Florida-based SeaWorld public last month in an $807 million share sale, called the last years under the brewer’s ownership ��a drought period.” [Blackstone] gave Atchison, who has held executive roles with SeaWorld since 1998, the go-ahead to crank up capital spending -- from $120 million in 2010 to $225 million the following year and $192 million in 2012.
