SeaWorld Entertainment CEO Joel Manby has resigned after the company posted a fourth-quarter revenue loss and a drop in park attendance despite the companys ongoing attempt to rebuild its image after the Blackfish documentary raised controversy.

Manbys departure Tuesday came the same day the company reported a loss of $20.4 million or 24 cents per share in the three months that ended on Dec. 31. In comparison, in the fourth quarter of 2016, the company reported a loss of $11.9 million, or 14 cents per share.

SeaWorld Entertainments stock closed at $14.97 a share Tuesday, a 25 percent drop from the stock price when Manby became CEO nearly three years ago, according to the San Diego Union-Tribune .

The fourth-quarter loss was worse than the 18 cents-per-share decline forecast by investment research firm Zacks Investment Research on Monday.
