Comverge To Record Non-Cash Impairment Charge

Comverge, Inc. a leading provider of clean energy through demand response and energy efficiency announced today that it expects to record a non-cash impairment charge of goodwill and certain intangible assets in the range of $65 million to $79 million for the three months ended September 30, 2008. The net non-cash impairment charge is estimated to increase diluted net loss per share by $3.05 to $3.71 per share. Comverge will release third quarter operating results after market close on November 11, 2008.

During the third quarter, Comverge concluded that it is likely that the fair value of one of its reporting units has been reduced below its carrying value. Comverge is currently conducting an interim goodwill and identifiable intangible asset impairment analysis, with the assistance of an independent third party valuation specialist, to determine the required amount of the non-cash impairment charge. This non-cash impairment charge, within the Enerwise segment, is primarily a result of less revenue being generated in the PJM territory, resulting from the rule change for economic demand response programs during 2008. The non-cash impairment charge will have no effect on Comverge’s cash balances, liquidity, borrowing capacity, or debt covenant compliance.

Robert M. Chiste, Chairman, President and CEO of Comverge, stated, “The impairment charge results from accounting rules primarily driven by a regulatory change. While PJM is currently considering new proposals which could provide alternative revenue streams, we have no assurance of that occurring. From a strategic standpoint, we believe that our acquisition of Enerwise in 2007 has made Comverge a strong participant in the commercial and industrial sector. Further, the Enerwise commercial and industrial expertise and technology have opened opportunities and allowed Comverge to win and execute on long-term C&I Virtual Peaking Capacity® contracts. In addition, we continue to expand our participation in open market programs in various geographies.”
