NEW YORK ( TheStreet) -- Facebook ( FB) reported its fourth-quarter results after the market close Wednesday, with investors keen to see whether the social-network company can keep making money from mobile. The social-networking giant led by CEO Mark Zuckerberg delivered, reporting non-GAAP earnings of 17 cents a share on $1.585 billion in revenue, as the company's top line jumped 40%. Revenue from advertising was up 41% to $1.33 billion, accounting for 84% of total revenue. Mobile revenue represented 23% of advertising revenue in the fourth quarter, up from 14% in the third quarter.

Payments and other fee revenue was $256 million, which was four months' worth of revenue for accounting reasons. Adjusting for the extra month, payments revenue was essentially flat. Facebook did not provide first-quarter 2013 guidance, but did note that capital expenditures for 2013 will be around $1.8 billion, as the company ramps up its hiring and infrastructure spending.
