"In order to achieve the goals of our business realignment, we regret that some positions will necessarily be eliminated," Atchison said in a statement. "However, our cost savings effort is part of a broader program to position us for long term growth."
The move comes amid a time of financial crisis for the company. On Wednesday, the SeaWorld's stock hit a new all-time low, dropping below $16 per share for the first time since its April 2013 initial public offering. Its market CAP has fallen by over $1 billion, and its stock has dropped over 50 percent since that time.
The backlash created by the documentary "Blackfish" likely contributed to the company's nosedive. The film revealed disturbing animal care practices at the park, including safety risks for trainers as well as psychosis, inbreeding and physical injuries among the whales.
SeaWorld has not responded to The Dodo's request for more information about Atchison's departure.
