FRAMINGHAM, MA - February 28, 2022 - Ameresco, Inc. (NYSE:AMRC), a leading cleantech integrator specializing in energy efficiency and renewable energy, today announced financial results for the fiscal quarter ended December 31, 2021. The Company has also furnished supplemental information in conjunction with this press release in a Current Report on Form 8-K. The supplemental information, which includes Non-GAAP financial measures, has been posted to the “Investor Relations” section of the Company’s website at www.ameresco.com. Reconciliations of Non-GAAP measures to the appropriate GAAP measures are included herein.

“Fourth quarter results capped a year of outstanding performance for Ameresco, demonstrating the strength of our diversified business model. Revenue growth was led by our Projects business strengthened by the Southern California Edison (SCE) design/build contract and was complemented by strong performance from our recurring revenue Energy Asset and O&M businesses. We ended the year with 343MWe of operating assets representing 22% year-over-year growth while continuing to expand our assets in development to 414MWe. Ameresco exited 2021 with total project backlog of over $3 billion and more than $2 billion in estimated contracted revenue and incentives from our recurring revenue O&M and Energy Asset businesses. This record multi-year revenue visibility sets the stage for robust long term profit growth. In addition, Ameresco released it’s 2021 ESG report, centering on the theme of Doing Well by Doing Good: Innovation. Action. Integrity. This report highlights Ameresco’s practices pertaining to business and operations, environmental advocacy and impact, employee engagement, giving back, health and safety, and corporate responsibility,” said George P. Sakellaris, President and Chief Executive Officer.

“In 2021 Ameresco was awarded the largest contract in its history providing utility scale battery energy storage systems (BESS) at three sites for SCE. Despite the well-publicized global supply chain challenges, we are pleased to report that the design/build project is proceeding as expected. Importantly this contract is representative of the types of the projects that are emerging as the power industry addresses grid stability and reliability. Our track record of execution on projects of increasing size and complexity puts Ameresco in a distinct competitive advantage to capture similar opportunities in the periods ahead. This project is also an excellent example of our ever expanding addressable market.”

Total revenue was up 32% with broad based growth across all our business lines. The Company began executing on and recognizing revenue related to the SCE BESS project leading to a 36% increase in Project revenue. The growth in our operating asset base, increased performance of existing assets and strong RIN prices drove a 35% growth in Energy Asset revenue. Gross margin was 17.1%, in line with our expectations given the impact from the lower gross margin profile of the SCE design/build project.

“We are pleased to provide guidance for what we expect to be another year of strong growth in 2022. Specifically, we expect revenues in the range of $1.83 billion to $1.87 billion, Adjusted EBITDA of $200 million to $210 million and Non-GAAP EPS to range from $1.85 to $1.95, representing year-over-year growth of 52%, 34% and 26% at the midpoints. During 2022, we anticipate placing between 60 and 80 MWe of energy assets in service, while investing approximately $225 million to $275 million in capital in 2022, the majority of which we expect to fund with non-recourse debt.

“2022 quarterly cadence will be meaningfully impacted by the timing of the SCE BESS contract. We anticipate first quarter revenue will be sequentially flat with our strong 2021 fourth quarter with total gross margin at approximately 14.5%. Revenue from the SCE BESS project is expected to peak during the second quarter, driving an approximately 40% sequential total revenue increase, with total gross margin for the quarter expected to be closer to 14.0%. Third quarter total revenue is expected to look similar to the first quarter, but total gross margin is expected to be approximately 17.5% due to project mix.”

“We expect that 2022 will be another record year for Ameresco. Our addressable markets continue to expand, driven by strong long term industry growth trends. These trends, together with the breadth of our technological expertise and proven track record position Ameresco to benefit from the growing number of opportunities in front of us. I have never been more excited about the prospects for Ameresco,” Mr. Sakellaris concluded.

We use the Non-GAAP financial measures defined and discussed below to provide investors and others with useful supplemental information to our financial results prepared in accordance with GAAP. These Non-GAAP financial measures should not be considered as an alternative to any measure of financial performance calculated and presented in accordance with GAAP. For a reconciliation of these Non-GAAP measures to the most directly comparable financial measures prepared in accordance with GAAP, please see Non-GAAP Financial Measures and Non-GAAP Financial Guidance in the tables above.

We understand that, although measures similar to these Non-GAAP financial measures are frequently used by investors and securities analysts in their evaluation of companies, they have limitations as analytical tools, and investors should not consider them in isolation or as a substitute for the most directly comparable GAAP financial measures or an analysis of our results of operations as reported under GAAP. To properly and prudently evaluate our business, we encourage investors to review our GAAP financial statements included above, and not to rely on any single financial measure to evaluate our business.

We define adjusted EBITDA as net income attributable to common shareholders, including impact from redeemable non-controlling interests, before income tax (benefit) provision, other expenses net, depreciation, amortization of intangible assets, accretion of asset retirement obligations, contingent consideration expense, stock-based compensation expense, energy asset impairment, restructuring and other charges, gain or loss on sale of equity investment, and gain or loss upon deconsolidation of a variable interest entity. We believe adjusted EBITDA is useful to investors in evaluating our 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 our adjusted EBITDA in different historical periods, investors can evaluate our operating results without the additional variations of depreciation and amortization expense, accretion of asset retirement obligations, contingent consideration expense, stock-based compensation expense, impact from redeemable non-

Our management uses adjusted EBITDA and adjusted EBITDA margin as measures of operating performance, because they do not include the impact of items that we do not consider indicative of our core operating performance; for planning purposes, including the preparation of our annual operating budget; to allocate resources to enhance the financial performance of the business; to evaluate the effectiveness of our business strategies; and in communications with the board of directors and investors concerning our financial performance.

We define Non-GAAP net income and earnings per share (EPS) to exclude certain discrete items that management does not consider representative of our ongoing operations, including energy asset impairment, restructuring and other charges, impact from redeemable non-controlling interest, gain or loss on sale of equity investment, and gain or loss upon deconsolidation of a variable interest entity. We consider Non-GAAP net income and Non-GAAP EPS to be important indicators of our operational strength and performance of our business because they eliminate the effects of events that are not part of the Company's core operations.

We define adjusted cash from operations as cash flows from operating activities plus proceeds from Federal ESPC projects. Cash received in payment of Federal ESPC projects is treated as a financing cash flow under GAAP due to the unusual financing structure for these projects. These cash flows, however, correspond to the revenue generated by these projects. Thus we believe that adjusting operating cash flow to include the cash generated by our Federal ESPC projects provides investors with a useful measure for evaluating the cash generating ability of our core operating business. Our management uses adjusted cash from operations as a measure of liquidity because it captures all sources of cash associated with our revenue generated by operations.
