Lime Energy Co. (NASDAQ: LIME) today announced that on Sunday, July 15, 2012, the Audit Committee of the Board of Directors of Lime Energy Co. (the “Company”) determined that the Company’s consolidated financial statements on Form 10-K for the periods ended December 31, 2010 and December 31, 2011 and quarterly report on Form 10-Q for the period ended March 31, 2012 (the “affected financial statements”) may no longer be relied upon. The Audit Committee made that determination based on the results of a partial internal review conducted by the Company’s management which was concluded on Friday, July 13, 2012. Based on the results of that partial internal review, the Company’s management and the Audit Committee believe that some portion of the Company’s revenue was improperly recorded. In some cases, it appears that non-existent revenue may have been recorded. In other cases, it appears that revenue may have been recorded earlier than it should have been. The review did not turn up any indication of improper customer billing. The Company cannot make a reliable estimate of the magnitude of the misreported revenue or the effects on the affected financial statements at this time; the Company does, however, currently believe that the cumulative adjustment to revenue for the affected financial statements will not exceed $15 million. The Company does expect that the misreporting may potentially require restatement of all of the affected financial statements. The Company, under the supervision of the Audit Committee and with the assistance of outside counsel, is currently conducting an investigation of the misreporting. The Audit Committee and Lime’s principal financial and accounting officer have discussed the matters disclosed in this report with Lime’s independent accountants, BDO USA, LLP.
