SeaWorld Entertainment (SEAS) - Get Report issued its preliminary 2016 full year financial results on Tuesday morning, reporting 22 million visitors in 2016, a slight decline from the 22.8 million visitors its parks welcomed in the previous year. Back in the summer, the company credited an overall decline in Orlando tourism for an attendance decline.

The company is expecting revenue of $1.34 billion vs. the $1.37 billion reporter a year ago.

SeaWorld has been dealing with a dip in attendance as public sentiment shifts away from keeping marine mammals in captivity.

SeaWorld Stock is gaining by more than 3% in mid-morning trading Tuesday. The company will release its full earnings report next week.
