How can you possibly come to such a conclusion?
The company achieved an adjusted EBITDA of $332 million in 2016, this would be a totally unrealistic figure if 40% of the company's top 5 parks (i.e-SWO & SWSD) were making losses.
I know that attendance does not always automatically equate to profitability but when combined, SeaWorld Orlando & San Diego contribute close to 40% of the company's annual attendance. Are you suggesting that two of the three largest parks owned by one of the world's largest theme park operators which contribute not far off half its attendance are not making money? The numbers just don't add up.
EBITDA is hard to use for theme parks because they generally operate with huge depreciation/amortization (which requires large capital expenditures to balance) and SeaWorld in particular has a high debt load: a theme park constantly has to spend money to rebuild its asset base as its assets decline in value.
I was going off of SeaWorld's Net Income, which accounts for the above. If you look at SeaWorld's revenue ($1.344 billion in 2016) and expenses ($1.284 billion in 2016) and interest ($63 million in 2016), you end up with a net income (loss) overall of -$12 million.
If you apportion those values out to the various parks based on performance (SeaWorld San Antonio is probably the healthiest overall followed by BGT/BGW and then SW San Diego and Orlando, you end up somewhere around:
SW Orlando's share probably looks something like $345 million in revenue, expenses around $365 million.
SW San Diego's share probably looks something like $270 million in revenue, expenses around $280 million.
SW San Antonio's share probably looks something like $195 million in revenue, expenses around $175 million.
BG Tampa's share probably looks something like $325 million in revenue, expenses around $285 million.
BG Williamsburg's share probably looks something like $205 million in revenue, expenses around $175 million.
Those estimates are based on a rough look at the various parks' attendances (as well as ticket prices/ap prices), and it's before we account for interest expense ($63 million in additional subtraction). FWIW, I do think SW Orlando and San Diego were extremely profitable 6-8 years ago when their attendance levels were much higher. BGT and BGW have lost some of their profitability over the past couple of years due to weaker attendance, but they haven't faced a dramatic decline. SW San Antonio's probably been the healthiest in that it's consistently grown since it opened.
