FalconStor Software, Inc. (NASDAQ: FALC), the provider of TOTALLY Open data protection solutions, today announced preliminary results for the first quarter ended March 31, 2010. Based on preliminary financial data, the Company expects first quarter revenue to be in the range of $16.8 to $17.1 million, non-GAAP operating loss to be between $5.8 and $6.0 million, and non-GAAP net loss per share to be between $0.08 and $0.09 per share. Non-GAAP results exclude the effects of stock-based compensation expense net of the related income taxes. The revenue shortfall was a result of lower than expected software license revenue. In particular, international software license revenue was down on a year over year basis.

“Although our results were lower than we anticipated, we are still experiencing a strong pipeline and interest for our innovative solutions which offer a compelling price/performance ratio,” said ReiJane Huai, Chairman and Chief Executive Officer of FalconStor. “In response to the revenue shortfall in the first quarter, we have delayed any additional hiring until we return to year over year revenue growth and we are evaluating other cost saving initiatives. We will not be giving any guidance for the year until our channel business reaches a steady predictable state.”

The Company will release final results for the first quarter on April 29, 2010 and will host a conference call to discuss its final financial results on Thursday, April 29, 2010 at 4:30 p.m. EDT. To participate in the conference call, please dial:

Non-GAAP Financial Measures

The non-GAAP financial measures used in this press release are not prepared in accordance with generally accepted accounting principles and may be different from non-GAAP financial measures used by other companies. The Company’s management refers to these non-GAAP financial measures in making operating decisions because they provide meaningful supplemental information regarding the Company’s operating performance. In addition, these non-GAAP financial measures facilitate management’s internal comparisons to the Company’s historical operating results and comparisons to competitors’ operating results. We include these non-GAAP financial measures (which should be viewed as a supplement to, and not a substitute for, their comparable GAAP measures) in this press release because we believe they are useful to investors in allowing for greater transparency into the supplemental information used by management in its financial and operational decision-making.
