The company dominated Facebook's annual game charts with 54 million of the approximately 800 million users playing Zynga games every single day in Q4 (roughly 4.25 million fewer than Zynga's annual average DAUs). And those users were buying up enough microtransacted goods to earn Zynga $1.07 billion solely online for the entirety of 2011, with a total of $1.14 billion earned in revenue for the year.
Now here's the bad news: despite earning over $1 billion in 2011, the company ended up with a net loss for the year of $404.3 million. According to the quarterly financials press release, Zynga paid out $510 million for "stock-based compensation expense for restricted stock units issued to employees" -- compensation it didn't have to pay until the company went public. The company's stock is currently trading $4.35 north of its introductory $10 price per share.
