Adjusted earnings were 49 cents a share. According to FactSet, analysts were expecting 47 cents a share.

Revenue rose 32% to $3.74 billion from $2.84 billion, but just shy of the $3.75 billion expected by analysts.

Operating expenses are projected to be between 29% and 30% of revenue, with free cash flow to be at the same levels as it was in the prior-year period.
