Depends on when the IPO was.
The union talk is very worrisome as an investor. If the stock becomes public before a union deal is reached ... you're going to be paying way too much based on the 4 billion dollar sale price. With a union you're going to start losing some of your profits, more threat of government intervention and I can't see more than 52 UFC events a year. Profits are going to go down, year after year.
I don't think the decision to buy the UFC was smart - 4 billion is way too much. Buy Bellator for much cheaper and spend a billion on luring popular UFC fighters away. Big names are what interests the public. Network TV made money from Kimbo Slice.
The UFC will be profitable but it's not a stock I would want. It has little upside.
