ORLANDO, Fla. – SeaWorld CEO Gus Antorcha has resigned, the company announced Monday.

Antorcha, who was hired in February, previously served as COO of Carnival Cruise Line.

"We thank Gus for his contributions and wish him well in his future endeavors," said Scott Ross, Chairman of Board of Directors, in a statement.

In Antorcha's place, SeaWorld's Chief Financial Officer Marc Swanson, has been appointed as interim CEO.

"Marc has been with the company for 19 years and has a deep understanding of the company, its parks and its strategy," Ross continued. "He has been a key contributor to the success of the business for several years."

SeaWorld said Antorcha's resignation was prompted by "disagreements over the board's involvement in the decision making at the company."

"While I may have a difference of approach, I continue to believe in SeaWorld's strategy, mission, team and prospects," Antorcha said in a statement.

The news of Antorcha's resignation comes the same day SeaWorld laid off 100 employees at its Orlando call center, moving operations to a third-party vendor. 

In recent years, SeaWorld has experienced a resurgence, reporting increased attendance and revenue. As part of its ongoing strategy, the company plans to open new attractions at its parks every year.

Last week, SeaWorld Orlando and Busch Gardens Tampa Bay shared additional details about their new coasters, which are set to open in 2020.
