NEW YORK (TheStreet) -- I've spent most of last year coming to the defense of Facebook (FB - Get Report). Although I no longer own the stock, I'm nonetheless amazed by the volume of criticism the company still absorbs.Granted, the botched IPO didn't win Facebook many friends. But over the past six months, it is clear that Facebook has grown -- literally. In many respects, this is a new company. Following a solid fourth-quarter performance, it's time investors take on a new perspective of what this social network giant can yet become. Facebook is transitioning itself from what it was, which was a PC-dependent platform. This means the company is in the midst of a pretty significant transition. With its user base having exceeded the one billion mark, there's more urgency for Facebook to reconfigure its approach. This quarter proved that it understands this. It's time for investors to start doing the same.
For the period ending in December, Facebook posted revenue of $1.59 billion representing 40% year-over-year growth and beating analysts' estimates of $1.52 billion. The company posted net income of $64 million, well ahead of estimates of $45.8 million. Likewise, the company beat EPS estimates by 2 cents, earning 17 cents per share. Mobile revenue was impressive, growing to 23% of Facebook gross revenue. Too, mobile monthly active users rose to 680 million, which means Facebook has begun to shed the most popular bear argument -- that it can't monetize mobile. This is the second consecutive quarter of mobile growth. Advertising revenue was up 41%, which was the same as in the third quarter, and fell slightly short of estimates. Likewise, ad pricing shed roughly 4%. Normally this would have been a bigger disappointment. But then again Google ( GOOG - Get Report) didn't exactly outperform in that area either as it reported a 6% drop in CPC or cost per click -- the metric that tracks how much companies pay for ads.
With a metric of $1.38, Facebook still lags behind Google's $9.16 in terms of average revenue per user. For that matter, Facebook is also behind Microsoft ( MSFT - Get Report). But all that means is the company has plenty of room to grow from the $1.59 billion in revenue it just reported.
Investors shouldn't discount Facebook's ability to enter the corporate enterprise, a potential gold mine for the company and investors. For example, if Facebook is able to adopt the enterprise benefits of Microsoft's Yammer by allowing employees to chat, share information and contact each other via private directories, Facebook's new corporate presence would then immediately rival that of LinkedIn ( LNKD). What's more, with the adoption of Facebook into Apple's ( AAPL - Get Report) mobile IOS as well as other investments made by Microsoft there are powerful allies in Facebook's corner. With one billion users now on hand, Facebook will have plenty of ways to make money. In the meantime, its growth trajectory puts its fair value at $40.
