GAAP EPS was positive only due to a $166 million gain from an acquisition.

Tower guided for $225 million in revenue for the first quarter of 2015, representing about 70% year-over-year growth. The company provided no guidance for earnings in its press release.

Investors considering buying shares of the company should first take a very deep look at its financials.
