EnerNOC Reports First Quarter 2009 Financial Results

Megawatt Additions, Utility Contract Wins, and Continued Operating Leverage Strengthen 2009 Outlook

BOSTON, May 6, 2009 (GLOBE NEWSWIRE) -- EnerNOC, Inc. (Nasdaq:ENOC), a leading developer and provider of clean and intelligent energy solutions, today announced financial results for the quarter ended March 31, 2009.

"The first quarter marked another period of high growth for EnerNOC," said Tim Healy, EnerNOC's Chairman and CEO. "We experienced the highest quarterly megawatt additions in our company's history. These record megawatt additions and high-profile utility contract wins are indicative of continued strong demand for EnerNOC's capital-efficient demand response and energy efficiency applications aimed at helping businesses and institutions manage and reduce energy costs."

"The advancements we are making in our innovative smart grid applications are enabling us to continue to increase our gross margin and operating leverage," Healy added. "Our strong start in the first quarter keeps us on track to deliver positive cash flow from operations in the second half of 2009 and positive GAAP earnings per share in 2010."

Safe Harbor Statement

Statements in this press release regarding management's future expectations, beliefs, intentions, goals, strategies, plans or prospects, including, without limitation, statements relating to the Company's future financial performance on both a GAAP and non-GAAP basis, the Company's ability to generate positive cash flow from operations in the second half of 2009 and to deliver positive earnings for the year ending December 31, 2010, and the future growth and success of the Company's demand response and energy management solutions, may constitute forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995. In addition, certain of the Company's contracts and expansion of existing contracts may be subject to approval of state or local regulatory agencies. There can be no assurance that such approvals will be obtained. Forward-looking statements can be identified by terminology such as "anticipate," "believe," "could," "could increase the likelihood," "estimate," "expect," "intend," "is planned," "may," "should," "will," "will enable," "would be expected," "look forward," "may provide," "would" or similar terms, variations of such terms or the negative of those terms.

As a result of such risks, uncertainties and factors, the Company's actual results may differ materially from any future results, performance or achievements discussed in or implied by the forward-looking statements contained herein.

Use of Non-GAAP Financial Measures

EnerNOC continues to provide all information required in accordance with GAAP and also provides certain non-GAAP financial measures. A "non-GAAP financial measure" refers to a numerical measure of the Company's historical or future financial performance, financial position, or cash flows that excludes (or includes) amounts that are included in (or excluded from) the most directly comparable measure calculated and presented in accordance with GAAP in the Company's financial statements. EnerNOC provides non-GAAP net loss and non-GAAP net loss per share data as additional information relating to EnerNOC's operating results. EnerNOC presents these non-GAAP financial measures as a complement to results provided in accordance with GAAP because management believes these non-GAAP financial measures help indicate underlying trends in the Company's business and are important in comparing current results with prior period results. The presentation of this additional information is not meant to be considered in isolation or as a substitute for net loss or net loss per share prepared in accordance with GAAP.

EnerNOC's management uses certain non-GAAP financial information, namely operating results excluding the impact of stock-based compensation charges made in accordance with SFAS 123R and amortization expense related to acquisition-related assets, to evaluate its ongoing operations and for internal planning and forecasting purposes. Accordingly, EnerNOC believes it is useful for its investors to review, as applicable, information that both includes and excludes stock-based compensation and amortization expense related to acquisition-related assets in order to assess the performance of EnerNOC's business and for planning and forecasting in future periods. Whenever EnerNOC reports non-GAAP financial measures, a reconciliation of the non-GAAP financial measure to the most closely applicable GAAP financial measure will be made available. Investors are encouraged to review these reconciliations to ensure they have a thorough understanding of the reported non-GAAP financial measures and their most directly comparable GAAP financial measures.

In EnerNOC's earnings releases, conference calls, slide presentations or webcasts, it may use or discuss non-GAAP financial measures as defined by SEC Regulation G. The GAAP financial measure most directly comparable to each non-GAAP financial measure used or discussed and a reconciliation of the differences between each non-GAAP financial measure and the comparable GAAP financial measure are included in this press release after the condensed consolidated financial statements and can be found on the Investor Relations page of the EnerNOC corporate Web site at http://investor.enernoc.com.

Reconciliation of Non-GAAP Financial Measures to Comparable U.S. GAAP Measures (Unaudited)

Pursuant to the requirements of Regulation G, the Company has provided a reconciliation of each non-GAAP financial measure used in this earnings release and related conference call or webcast to the most directly comparable financial measure prepared in accordance with accounting principles generally accepted in the United States ("GAAP"). The reconciliation for historic non-GAAP measures is provided herein on a quantitative basis and for non-GAAP measures that are forward-looking is provided herein on a qualitative basis.

The non-GAAP measures used in this earnings release and related conference call differ from GAAP in that they exclude expenses related to stock-based compensation and amortization expense related to acquisition-related assets.. The Company's basis for these adjustments is described below. Management uses these non-GAAP measures for internal reporting and forecasting purposes. The Company has provided these non-GAAP financial measures in addition to GAAP financial results because it believes that these non-GAAP financial measures provide useful information to certain investors and financial analysts for comparison across accounting periods not influenced by certain non-cash items that are not used by management when evaluating the Company's historical and prospective financial performance.

Management uses these non-GAAP financial measures when evaluating the Company's operating performance and believes that such measures are useful to investors and financial analysts in assessing the Company's operating performance due to the following factors:



 * The Company believes that the presentation of non-GAAP measures
   that adjust for the impact of stock-based compensation expenses
   and amortization expense related to acquisition-related assets
   provides investors and financial analysts with a consistent basis
   for comparison across accounting periods and, therefore, are useful
   to investors and financial analysts in helping them to better
   understand the company's operating results and underlying
   operational trends.

 * Although stock-based compensation is an important aspect of the
   compensation of the Company's employees and executives, stock-based
   compensation expense is generally fixed at the time of grant, then
   amortized over a period of several years after the grant of the
   stock-based instrument, and generally cannot be changed or
   influenced by management after the grant.

 * The Company does not acquire intangible assets on a predictable
   cycle. The Company's intangible assets relate solely to business
   acquisitions.  Amortization costs are fixed at the time of an
   acquisition, are then amortized over a period of several years
   after the acquisition and generally cannot be changed or influenced
   by management after the acquisition.

These non-GAAP financial measures are not prepared in accordance with GAAP. These measures may differ from the non-GAAP information, even where similarly titled, used by other companies and therefore should not be used to compare the Company's performance to that of other companies. There are significant limitations associated with the use of non-GAAP financial measures. The additional non-GAAP financial information presented here should be considered in conjunction with, and not as a substitute for or superior to, the financial information presented in accordance with GAAP (such as net income and earnings per share) and should not be considered measures of the Company's liquidity.
