Statement on Use of Non-GAAP Financial Measures

To supplement the Company’s consolidated financial statements presented on a GAAP basis, the Company discloses certain non-GAAP measures that exclude certain amounts, including non-GAAP net (loss) income attributable to EnerNOC, Inc., non-GAAP net (loss) income per share attributable to EnerNOC, Inc., adjusted EBITDA and free cash flow. These non-GAAP measures are not in accordance with, or an alternative for, generally accepted accounting principles in the United States.

The GAAP measure most comparable to non-GAAP net (loss) income attributable to EnerNOC, Inc. is GAAP net (loss) income attributable to EnerNOC, Inc.; the GAAP measure most comparable to non-GAAP net (loss) income per share attributable to EnerNOC, Inc. is GAAP net (loss) income per share attributable to EnerNOC, Inc.; the GAAP measure most comparable to adjusted EBITDA is GAAP net (loss) income attributable to EnerNOC, Inc.; and the GAAP measure most comparable to free cash flow is cash flows provided by operating activities. Reconciliations of each of these non-GAAP financial measures to the corresponding GAAP measures are included below.

Management uses these non-GAAP measures when evaluating the Company’s operating performance and for internal planning and forecasting purposes. Management believes that such measures help indicate underlying trends in the 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, management considers non-GAAP net (loss) income attributable to EnerNOC, Inc. to be an important indicator of the overall performance because it eliminates the effects of events that are either not part of the Company’s core operations or are non-cash compensation expenses. In addition, management considers adjusted EBITDA to be an important indicator of the Company’s operational strength and performance of the business and a good measure of the Company’s historical operating trend. Moreover, management considers free cash flow to be an indicator of the Company’s operating trend and performance of the business.

The following is an explanation of the non-GAAP measures that management utilizes, including the adjustments that management excluded as part of the non-GAAP measures for the three month periods ended March 31, 2014 and 2013, respectively, as well as reasons for excluding these individual items:

Non-GAAP net (loss) income attributable to EnerNOC, Inc., non-GAAP net (loss) income per share attributable to EnerNOC, Inc., adjusted EBITDA and free cash flow may have limitations as analytical tools. 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.
