So what

Pareteum's fourth-quarter revenue soared 256% year over year to $14.3 million. Revenue was helped by the company's acquisition of Artilium -- a mobile virtual network and Internet of Things enabler -- in late September. 

Pareteum's non-GAAP earnings per share for the period were $0.02, even with its non-GAAP earnings per share in the year-ago quarter.

Analysts, on average, were expecting revenue of around $13 million and non-GAAP EPS of $0.01.
