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, demand for the Company’s offerings, projected megawatt growth in the Company’s portfolio, and the future growth and success of the Company’s clean and intelligent energy management applications and services in general, may constitute forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995 and other federal securities laws. 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. Such forward-looking statements involve known and unknown risks, uncertainties and other factors including those risks, uncertainties and factors referred to under the section “Risk Factors” in EnerNOC’s most recent Annual Report on Form 10-K and subsequent Quarterly Reports on Form 10-Q, as well as other documents that may be filed by EnerNOC from time to time with the Securities and Exchange Commission. 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. EnerNOC is providing the information in this press release as of this date and assumes no obligations to update the information included in this press release or revise any forward-looking statements, whether as a result of new information, future events or otherwise.

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 income or loss, non-GAAP net income or loss 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 defines “non-GAAP net income (loss)” as net income (loss) before expenses related to stock-based compensation and amortization expenses related to acquisition-related intangible assets, net of related tax effects.
	•		EnerNOC defines “Adjusted EBITDA” as net income (loss), excluding depreciation, amortization, stock-based compensation, interest, income taxes and other income (expense). Adjusted EBITDA eliminates items that are either not part of the Company’s core operations or do not require a cash outlay, such as stock-based compensation. Adjusted EBITDA also excludes depreciation and amortization expense, which is based on the Company’s estimate of the useful life of tangible and intangible assets. These estimates could vary from actual performance of the asset, are based on historic cost incurred to build out the Company’s deployed network, and may not be indicative of current or future capital expenditures.
	•		EnerNOC defines “free cash flow” as net cash provided by (used in) operating activities less capital expenditures. EnerNOC defines “capital expenditures” as purchases of property and equipment, which includes capitalization of internal-use software development costs. Capital expenditures are disclosed in the Company’s Statement of Cash Flows in the Company’s most recent Annual Report on Form 10-K filed with the Securities and Exchange Commission.

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 income (loss) to be an important indicator of the overall performance of the Company 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, 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.
