Digital Turbine (APPS -14.52%) stock is getting crushed Wednesday following the company's latest earnings report. The digital marketing player's share price was down 18% as of 1 p.m. ET.

After the market closed yesterday, Digital Turbine published results for the first quarter of its current fiscal year -- a period that ended June 30. Despite raising its full-year sales outlook in conjunction with the report, the company's stock is falling due to investors' concerns about profitability.

Digital Turbine stock sinks on Q1 profit miss

Digital Turbine recorded non-GAAP (adjusted) earnings per share of $0.05 on revenue of $130.92 million in fiscal Q1. While sales for the period beat the average Wall Street analyst estimate by roughly $9 million, the company's earnings per share came in $0.03 lower than the target. Sales were up roughly 9% year over year and were strong enough to cause the digital marketing specialist to issue a significant increase for its full-year revenue outlook, but weaker-than-anticipated margins are causing investors to sell out of the stock.

What's next for Digital Turbine?

Digital Turbine is now guiding for full-year revenue to come in between $525 million and $535 million -- up from its previous guidance for sales to be between $515 million and $525 million. While the target increase is a significant one, it looks like most of the projected sales beat was already recorded last quarter. Given that last quarter's big sales beat also arrived with weaker-than-expected earnings, investors are taking a more cautious stance on the stock's outlook.
