Shares of online education provider 2U Inc. (TWOU - Get Report) sank last fall after an investing newsletter questioned its pipeline, valuation and business model. The stock has since come back to the levels before Citron Research released its skeptical report and the company's CEO Chip Paucek said he is looking forward, not back. The Landover, Maryland-based company lost $0.07 a share in its first quarter. Adjusted earnings came in at less than $0.01 a share, beating the consensus forecast for a loss of $0.04 a share. 2U posted revenue of $47.4 million in the period, topping the Wall Street estimate of $46.6 million. Paucek said 2U expects full-year earnings to range from a loss of $0.18 a share to a loss of $0.21 a share, with sales between $199.7 million and $201.5 million.
