BOSTON, MA, November 5, 2012 – EnerNOC, Inc. (NASDAQ: ENOC) (the “Company”), a leading provider of energy management applications, services and products, today announced financial results for the third quarter ended September 30, 2012.

“We had a strong summer operationally, delivering a record 85 GWh of demand response with average performance above 100%,” said Tim Healy, Chairman and CEO of EnerNOC. “Our financial performance this quarter is a result of our industry-leading big data platform for energy management, portfolio management expertise, and ongoing profitability initiatives. Based on our success managing our portfolio in the PJM Interconnection region under new measurement and verification rules, coupled with strong pricing tailwinds, favorable capacity auction results, and our increased focus on operational excellence, we are raising the midpoints of our guidance for 2012 and 2013.”

Third Quarter 2012 and Recent Highlights

Third Quarter 2012 Financial Highlights

Revenues – Revenues for the third quarter totaled $177.9 million, compared with $169.2 million in the third quarter of 2011, an increase of 5.2%, primarily due to an increase in revenues from the Company’s Western Australia demand response capacity program. As a result of recent changes to certain PJM program rules, all 2012 revenues from the Company’s PJM Emergency Load Response Program (ELRP) were recognized during the three months ended September 30, 2012, compared to the four months ended September 30, 2011. However, the increase in third quarter ELRP revenues due to the change in timing of revenue recognition was more than offset by the decrease in the Company’s 2012 PJM ELRP MW delivery obligation coupled with less favorable pricing in this program.

Gross profit and gross margin – Gross profit for the third quarter was $95.0 million, compared with $84.8 million in the third quarter of 2011, an increase of 12.0%. Gross margin increased to 53.4% from 50.1% in the third quarter of 2011, primarily due to improved management of the Company’s portfolio of demand response capacity, including the Company’s participation in PJM incremental auctions and lower costs associated with C&I contracts.

Operating expenses – Third quarter operating expenses were $35.7 million, an increase of 5.4% from the third quarter of 2011, driven primarily by an increase in headcount from 587 full-time employees to 660 full-time employees. This increase was partially offset by improved operating leverage and improved overall cost management.

Income tax benefit – Income tax benefit for the third quarter was $0.7 million. The income tax benefit primarily represents the reversal of the income tax provision recorded during the first six months of 2012 as a result of a change in the Company’s ability to reliably estimate its annual effective tax rate. The Company expects an overall tax provision for the full year 2012 of approximately $1.5 million.

Net income– GAAP net income for the third quarter was $60.3 million, compared to net income of $46.9 million for the third quarter of 2011. GAAP earnings per share for the third quarter of 2012 was $2.21 per diluted share, compared to $1.77 for the third quarter of 2011. Excluding stock-based compensation and amortization expense related to acquired intangible assets, non-GAAP net income was $65.5 million or $2.40 per diluted share, compared to $52.1 million and $1.96 per diluted share for the same quarter last year.

Capital expenditures – Capital expenditures for the third quarter were $2.6 million, a 13.5% year-over-year decrease, partially due to a decrease in the Company’s equipment costs per customer site installation.

Cash and cash equivalents – Cash and cash equivalents as of September 30, 2012 grew to $93.2 million from $87.3 million as of December 31, 2011, primarily driven by net cash provided by operating activities.

Financial Outlook

The Company currently expects to deliver the following financial results for the years ending December 31, 2012 and December 31, 2013:

Full Year 2012: The Company expects full year 2012 revenues to be in the range of $270 million to $280 million, compared to its previously published 2012 guidance range of $260 million to $280 million. GAAP net loss for 2012 is expected to be in the range of $0.80 to $0.95 per basic and diluted share, compared to the Company’s previously published 2012 guidance range of a net loss of $1.00 to $1.40 per basic and diluted share. These revised estimates continue to be based on basic and diluted weighted average shares outstanding of 26.6 million. Full year 2012 Adjusted EBITDA is expected to be between $15 million and $20 million, compared to the Company’s previously published 2012 guidance range of $5 million to $20 million. The Company expects stock-based compensation expense to be approximately $14 million, amortization of acquisition related intangibles expense to be approximately $7 million, depreciation expense to be approximately $18 million, and interest and other expense, net, to be between $0 and $0.5 million. The estimated provision for income taxes is expected to be approximately $1.5 million.

Full Year 2013: The Company expects full year 2013 revenues to be in the range of $360 million to $400 million, compared to its previously published guidance range of $350 million to $400 million. GAAP net income for 2013 is expected to be in the range of $0.50 to $0.75 per diluted share, compared to the Company’s previously published 2013 guidance range $0.15 to $0.75 per diluted share. These revised estimates are based on diluted weighted average shares outstanding of 28 million compared to 27.7 million diluted shares used as the basis for the Company’s previously published guidance. Full year 2013 Adjusted EBITDA is expected to be between $60 million and $75 million, compared to the Company’s previously published guidance range of $50 million to $75 million. The Company expects stock-based compensation expense to be between $12 million and $14 million, amortization of acquisition related intangibles expense to be approximately $7 million, depreciation expense to be between $20 million and $23 million, and

interest and other expense, net, to be between $1 million and $2 million. The estimated provision for income taxes is expected to be between $6 million and $8 million.

These statements are forward-looking and actual results may differ materially. These statements are based on information available as of November 5, 2012, and the Company assumes no obligation to publicly update or revise its financial outlook. Investors are reminded that actual results may differ from these estimates for the reasons described below and in the Company’s filings with the Securities and Exchange Commission.

The Company’s projected net loss/income in 2012 and 2013 does not reflect any foreign exchange gains or losses. The 2012 and 2013 earnings outlook also does not take into account the potential impact of any future acquisitions or divestitures, including potential non-recurring acquisition related expenses or asset impairments. The outlook also does not take into account the effect of a public offering or other financing arrangement or debt restructuring that could impact outstanding shares and thereby the Company’s EPS outlook.

The Company is presenting projected net loss/income for both 2012 and 2013 without the impact of those items because it is currently unable to estimate the amount of those items and it believes that presenting net loss/income without taking them into account presents investors with meaningful information about the Company’s projected operating performance for 2012 and 2013.

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, non-GAAP net 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 income or loss 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.
