The Guardian reports:

The company, which trains dolphins and killer whales to perform tricks in front of stadiums full of spectators, on Thursday reported declines in attendance, sales and profits because of "continued brand challenges".

SeaWorld has been in the headlines since the 2013 documentary Blackfish detailed claims that its treatment of orca whales provoked violent behaviour contributing to the deaths of three people. Following the release of the documentary, attendance collapsed and the company lost more than half of its market value on Wall Street and its former CEO was forced out.
