Use of Non-GAAP Financial Measures

To supplement the financial measures presented in EnerNOC’s press release and related conference call or webcast in accordance with accounting principles generally accepted in the United States (“GAAP”), EnerNOC also presents non-GAAP financial measures relating to non-GAAP net (loss) income, non-GAAP net (loss) income per share, adjusted EBITDA, and free cash flow.

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 the non-GAAP measures listed above as additional information relating to EnerNOC’s operating results as a complement to results provided in accordance with GAAP. The 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 and should not be considered measures of the Company’s liquidity. There are significant limitations associated with the use of non-GAAP financial measures. Further, 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.

The non-GAAP measures used in this press release and related conference call or webcast differ from GAAP in that they exclude expenses related to stock-based compensation, amortization expense related to acquisition-related intangible assets, as well as in certain measures, the related impact of these adjustments on the provision for income taxes. In addition, investors should note the following:

EnerNOC’s management uses these non-GAAP measures when evaluating the Company’s operating performance and for internal planning and forecasting purposes. EnerNOC’s management believes that such measures help indicate underlying trends in the Company’s business, are important in comparing current results with prior period results, and are useful to investors and financial analysts in assessing the Company’s operating performance. For example, EnerNOC’s management considers non-GAAP net loss or income to be an important indicator of the overall performance of the Company because it eliminates certain of the more significant effects of its acquisitions and related activities and non-cash compensation expenses. In addition, EnerNOC’s management considers adjusted EBITDA to be an important indicator of the Company’s operational strength and performance of its business and a good measure of the Company’s historical operating trend. Moreover, EnerNOC’s management considers free cash flow to be an indicator of the Company’s operating trend and performance of its business.
