Ameresco, Inc. (NYSE:AMRC) a leading energy efficiency and renewable energy company, today announced financial results for the fiscal quarter ended June 30, 2012. The Company has also furnished prepared remarks in conjunction with this press release in a Current Report on Form 8-K. Those prepared remarks contain supplemental information, including non-GAAP financial metrics, and have been posted to the “Investor Relations” section of the Company’s website at www.ameresco.com.

Total revenue for the second quarter of 2012 was $164.1 million, compared to $165.5 million for the same period in 2011, a decrease of 0.8% year-over-year. Operating income for the second quarter of 2012 was $8.3 million, compared to $13.4 million for the second quarter of 2011, a decrease of 38.2% year-over-year. Second quarter 2012 adjusted EBITDA, a non-GAAP financial measure, was $13.9 million, compared to $16.9 million for the same period in 2011, a decrease of 17.8% year-over-year. Net income for the second quarter of 2012 was $5.2 million, compared to $8.8 million for the same period of 2011, a decrease of 41.5% year-over-year. Second quarter 2012 net income per diluted share was $0.11, compared to $0.19 per diluted share for the same period of 2011.

“Ameresco delivered second quarter financial results in line with expectations,” stated George P. Sakellaris, President and Chief Executive Officer of Ameresco. “During the quarter, we continued to execute well on projects in construction, awarded projects increased 40%, total construction backlog reached record levels and revenue from all other offerings increased 56%. However, we are disappointed by the pace of converting awarded projects to signed contracts in a few segments, which is causing us to revise our revenue and net income guidance for 2012. We believe that once normal conversion timing returns in all segments that we will be well positioned for future growth.”

For the six months ended June 30, 2012, we reported total revenue of $310.7 million, compared to $311.9 million for the same period in 2011, a decrease of 0.4% year-over-year. Operating income for the first six months of 2012 was $11.7 million, compared to $21.7 million for the first six months of 2011, a decrease of 46.1% year-over-year. Adjusted EBITDA for the first six months of 2012 was $23.1 million, compared to $28.8 million for the first six months of 2011, a decrease of 19.9% year-over-year. Net income for the first six months of 2012 was $6.7 million, compared to $14.1 million for the first six months of 2011, a decrease of 52.7% year-over-year. Net income per diluted share was $0.14 for the first six months of 2012, compared to $0.31 for the first six months of 2011.

Additional Second Quarter 2012 Operating Highlights:

• Revenue generated from backlog was $119.8 million for the second quarter of 2012, a decrease of 12.7% year-over-year.
• All other revenue was $44.8 million for the second quarter of 2012, an increase of 55.6% year-over-year.
• Operating cash flows were $6.3 million for the second quarter of 2012.
• Total construction backlog was $1.3 billion as of June 30, 2012 and consisted of:
  • $390.7 million of fully-contracted backlog, which represents signed customer contracts for installation or construction of projects that are expected to convert into revenue over the next 12-24 months, on average; and
  • $909.6 million of awarded projects, which represents estimated future revenue for projects for which contracts are expected to be signed over the next 6-12 months, on average.

FY 2012 Guidance

Ameresco is revising its guidance for the fiscal year ending December 31, 2012. As stated previously, guidance assumed continued improvement in the environment for converting awarded projects to signed contracts for the balance of the year. While awarded projects are converting into signed contracts in many regions as expected, we have experienced a lengthening of backlog conversion times in a few segments, and as a consequence, a portion of revenue that was previously expected to be recognized in the second half of 2012 is now expected to be recognized in 2013. The Company now expects total revenue to be in the range of $695 million to $730 million; and net income in the range of $32 million to $35 million.

Exhibit A: Non-GAAP Financial Measures

Ameresco defines adjusted EBITDA as operating income before depreciation, amortization of intangible assets and share-based compensation expense. Adjusted EBITDA is a non-GAAP financial measure and should not be considered as an alternative to operating income or any other measure of financial performance calculated and presented in accordance with GAAP.

The Company believes adjusted EBITDA is useful to investors in evaluating its operating performance for the following reasons: adjusted EBITDA and similar non-GAAP measures are widely used by investors to measure a company’s operating performance without regard to items that can vary substantially from company to company depending upon financing and accounting methods, book values of assets, capital structures and the methods by which assets were acquired; securities analysts often use adjusted EBITDA and similar non-GAAP measures as supplemental measures to evaluate the overall operating performance of companies; and by comparing Ameresco’s adjusted EBITDA in different historical periods, investors can evaluate its operating results without the additional variations of depreciation and amortization expense, and share-based compensation expense.

Ameresco’s management uses adjusted EBITDA: as a measure of operating performance, because it does not include the impact of items that management does not consider indicative of our core operating performance; for planning purposes, including the preparation of the annual operating budget; to allocate resources to enhance the financial performance of the business; to evaluate the effectiveness of Ameresco’s business strategies; and in communications with the board of directors and investors concerning Ameresco’s financial performance.

The Company understands that, although measures similar to adjusted EBITDA are frequently used by investors and securities analysts in their evaluation of companies, adjusted EBITDA has limitations as an analytical tool, and investors should not consider it in isolation or as a substitute for GAAP operating income or an analysis of Ameresco’s results of operations as reported under GAAP. Some of these limitations are: adjusted EBITDA does not reflect the Company’s cash expenditures or future requirements for capital expenditures or other contractual commitments; adjusted EBITDA does not reflect changes in, or cash requirements for, Ameresco’s working capital needs; adjusted EBITDA does not reflect stock-based compensation expense; adjusted EBITDA does not reflect cash requirements for income taxes; adjusted EBITDA does not reflect net interest income (expense); although depreciation, amortization and impairment are non-cash charges, the assets being depreciated, amortized or impaired will often have to be replaced in the future, and adjusted EBITDA does not reflect any cash requirements for these replacements; and other companies in Ameresco’s industry may calculate adjusted EBITDA differently than it does, limiting its usefulness as a comparative measure.

To properly and prudently evaluate Ameresco’s business, the Company encourages investors to review its GAAP financial statements included above, and not to rely on any single financial measure to evaluate the business. Please refer to the above reconciliation of adjusted EBITDA to operating income, the most directly comparable GAAP measure.
