Angry birds and pigs are quite a money-making combination it seems. Rovio today announced its 2011 financial results: yearly revenue totaled approximately $106.3 million, which generated $67.6 million in pre-tax profit. It should be noted here that Angry Birds Space, which was a blockbuster in terms of sales, isn’t included here since it was released this year. The 2011 lineup consists of Angry Birds, Angry Birds Seasons, and Angry Birds Rio, the movie tie-in.

Rovio also noted that the number of game downloads went up to 648 million by the end of the year, and that they’ve reached 200 million active monthly users. It also noted that around 30 percent of its total revenue was generated by licensing and merchandising.

The company also noted that it’s “preparing itself and getting ready” for an IPO. It will be expanding itself through “product development, cutting-edge branding… corporate infrastructure” this year, according to company CEO Mikael Hed.

Sounds like there’s more Angry Birds in our future!
