The top line beat the $2.34B that analysts expected. Adjusted earnings per share, at 31 cents, also topped predictions for 27 cents. Facebook 1Ad sales were up 76% to $2.34B, with 53% of the total coming from mobile ads — a big jump from last year when they accounted for 23% of the total. The number of daily active users was up 22% to 757M vs the end of 2012. The growing company also had growing expenses: They amounted to $1.5B in Q4, +37% which the company attributes to the rising headcount and infrastructure expenses.
