The results, which come on the heels of weaker-than-expected results from online search leader Google Inc., signal that Facebook's aggressive push into the mobile advertising market continues to pay off. The company began showing mobile advertisements for the first time last spring. On Wednesday, Facebook said mobile ads accounted for a whopping 41 per cent of its total advertising revenue.
The Menlo Park, California-based company's stock jumped $4.48, or 17 per cent, to $30.99 in extended trading. The shares had closed the regular trading session at $26.51. Facebook's stock priced at $38 when the company went public in May 2012, but hasn't hit that level since.
"I'm completely surprised," said Gartner analyst Brian Blau, summing up the sentiments of many investors who've watched Facebook's stock price stagnate over the past year due in large part to concerns about its mobile prospects.
"I was actually thinking that maybe they would have a soft quarter," he added, citing a softening of display advertising revenue — Facebook's bread and butter — across the industry. "That seems not to be the case."
Facebook Inc. earned $333 million, or 13 cents per share, in the April-June period. That's up from a loss of $157 million, or 8 cents per share, in the same period a year ago. Adjusted earnings were $488 million, or 19 cents per share in the latest quarter, above the 14 cents that analysts were expecting.
Facebook's revenue grew 53 per cent to $1.81 billion from $1.18 billion, well above the $1.62 million that analysts polled by FactSet were expecting. The company has also quickened the pace of its revenue growth. In the first quarter, revenue grew 38 per cent and in the fourth quarter of last year, 40 per cent.
Jefferies analyst Brian Pitz called the quarter's results "impressive" and noted that Facebook saw its highest revenue growth since the fourth quarter of 2011, when it was still a private company.
Mobile ad revenue was $655.6 million, or 41 per cent of the quarter's total advertising revenue of $1.6 billion. In the first quarter, mobile accounted for 30 per cent of total ad revenue.
"We've made good progress growing our community, deepening engagement and delivering strong financial results, especially on mobile," said CEO Mark Zuckerberg, in a statement. "The work we've done to make mobile the best Facebook experience is showing good results and provides us with a solid foundation for the future."
Research firm eMarketer expects Facebook to increase its mobile advertising revenue more than fourfold to over $2 billion this year. This would give the company a 13 per cent share of the global mobile ad market, up from about 5 per cent last year.
That said, Google is a distant No. 1 when it comes to mobile ads. EMarketer estimates that the company held a 52 per cent share of the global $8.8 billion mobile ad market last year. This year, the firm expects Google's share to grow to 56 per cent.
In a conference call with analysts, Zuckerberg sought to ease concerns that teenagers are growing tired of Facebook and flocking to newer, hipper services such as (Facebook-owned) Instagram.
"Based on our data, that isn't true," he said. "It's difficult to measure this perfectly since some young people lie about their age, but based on the best data we have, we believe we have close to fully penetrated in the U.S. teen demographic for a while, and the number of teens using Facebook on a daily and monthly basis has been steady over the past year and a half."
Facebook has also been working to increase its international advertising revenue, since most of its users live outside of the United States. The company announced this week that more than 100 million people access Facebook using traditional, non-smart phones in countries like India, Indonesia and the Philippines.
More than 53 per cent, or $965 million, of the quarter's revenue came from outside the U.S. and Canada.
Facebook had 1.15 billion monthly active users as of June 30, up 21 per cent from a year ago. The number of monthly mobile users grew 51 per cent to 819 million.
