Facebook's Q1 rides mobile surge, with slight earnings miss


The social network came in with earnings per share of 12 cents, excluding one-time items, and revenue that grew 38 percent to $1.46 billion compared to the same quarter one year ago. The company said mobile advertising accounted for around 30 percent -- which amounts to about $375 million -- of its advertising revenue for the quarter. Revenue from advertising in the quarter totaled $1.25 billion, or 85 percent of total revenue.
Facebook had 1.11 billion monthly active users as of March 31. The company grew its daily active users to 665 million people, which is an increase of 26 percent year over year. Facebook saw the most explosive growth in mobile active users; it had 751 million monthly mobile active users by quarter's end, marking 54 percent year-over-year growth.
"We've made a lot of progress in the first few months of the year," Chief Executive Mark Zuckerberg said in a statement. "We have seen strong growth and engagement across our community and launched several exciting products."
Heading into Wednesday, Wall Street anticipated $1.44 billion in revenue and adjusted earnings per share of 13 cents, which means Facebook beat revenue expectations but missed on earnings. Analysts were expecting to see $1.25 billion in advertising revenue with around 27 percent, or $340 million, coming from mobile advertising efforts. So Facebook didn't disappoint on either of those fronts.
