Ameresco, Inc. (NYSE:AMRC), a leading cleantech integrator specializing in energy efficiency and renewable energy, today announced financial results for the fiscal quarter ended September 30, 2022. The Company 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 "Investors" section of the Company's website at www.ameresco.com. Reconciliations of Non-GAAP measures to the appropriate GAAP measures are included herein.

"Ameresco delivered another quarter of excellent results. We are adapting to the reality of the supply chain environment and continue to execute effectively on our long-term growth strategy. Each of our business lines showed solid year-on-year growth, reflecting the benefits of our diversified business model and our ability to provide customers with innovative end-to-end solutions. The scope and comprehensive nature of our engagements continue to increase, and notable wins in the European market and increasing activity in the commercial and industrial (C&I) sector demonstrated our success in expanding Ameresco's addressable market.

Ameresco is providing an update on the progress of the Southern California Edison (SCE) battery energy storage systems (BESS) projects. The SCE projects saw continued progress in the quarter, with all battery cells and containers on site and early commissioning steps underway. SCE also recently instructed us to adjust the project schedules into 2023. Under the terms of the contract, Ameresco is entitled to recover costs associated with this schedule adjustment. We are working with SCE to analyze and estimate these costs. We are also continuing discussions regarding the applicability and scope of any force majeure relief based on the force majeure notices we delivered to SCE and the impact the schedule adjustments requested by SCE may have on the overall project schedule and our force majeure claims. Our relationship with SCE continues to be cooperative. Considering the schedule adjustments requested by SCE and the delays disclosed earlier, we anticipate the projects to be in service and achieve substantial completion prior to the summer of 2023.

During the quarter we were honored to become a Great Place to Work-Certified™ company for the first time. The designation is based entirely on employee input making it more meaningful as it reflects the positive experience of our over 1,300 employees. At Ameresco, we believe in doing well by doing good, which underpins our investments in the training and well-being of our employees," concluded George P. Sakellaris, President and Chief Executive Officer.

Third Quarter Financial Results

(All financial result comparisons made are against the prior year period unless otherwise noted.)

Total revenue increased 61% with growth across all of the Company's lines of business. Project revenue increased 81% as we continued to execute on the SCE projects. Energy Asset revenue grew 6% despite unplanned maintenance and downtime at two of our RNG facilities. O&M revenue increased 9% as the company continued to add long-term O&M contracts, especially on larger Federal government projects. Other revenue grew 28% with strength in integrated PV sales, especially to the oil & gas industry for remote power applications. Gross margin expanded sequentially to 18.0%, which was in line with our expectations, given a smaller contribution to our overall revenue mix in the quarter from the lower margin SCE design/build projects as they near completion. Revenue performance together with the Company's strong operating leverage led to a 57% increase in net income to $27.4 million, and a 44% increase in Adjusted EBITDA to $57.9 million. The results for the three months ended September 30, 2022 and 2021 reflect a non-cash downward adjustment of $0.3 million and $2.9 million, respectively, related to redeemable non-controlling interest activities. The current quarter results also reflect a non-cash downward adjustment of $1.1 million to recognize additional contingent consideration related to the Company's Smart Building Solutions business unit which was acquired in 2021. Working capital needs increased slightly from second quarter 2022 levels, in-line with our expectations due to the continued execution of our large SCE design/build projects. The company ended the quarter with approximately $123 million of available cash and generated nearly $87 million in adjusted cash from operations.

Project Highlights

In the Third Quarter of 2022:

Ameresco, and partner Sunel, were selected by Cero Generation, as the contractors for "Delfini", a 100 MWp solar photovoltaic (PV) project in Drama, Greece.
Ameresco was awarded a new project to install a microgrid system at White Sands Missile Range to provide resilient power for several of the base's potable water wells. The microgrid includes a new 700kW solar photovoltaic array, a 500kW natural gas generator and a 500kW battery energy storage system and is designed to provide 14 days of power in the event of an outage.
Ameresco was awarded a comprehensive utility savings project in partnership with Southwest Gas at Fort Irwin, CA for $98M.
The Company completed a 2.6 MW "brightfield" solar installation on a former General Motors Plant brownfield site in Danville, Illinois.
Ameresco announced phase two of a longstanding partnership with Joint Base McGuire-Dix-Lakehurst (JBMDL) to provide mission-critical energy infrastructure updates at the joint base as part of a comprehensive $92 million project designed to add more onsite solar power, energy efficiency measures, and infrastructure upgrades.

Asset Highlights

In the Third Quarter of 2022:

Ameresco continued to grow its Assets in Development, bringing the total to 501 MWe. After subtracting Ameresco's partners' minority interests, Ameresco's owned capacity of Assets in Development is 452 MWe.
Ameresco, together with Colorado Mountain College and Holy Cross Energy, partnered to install and complete 5MW of solar PV and 15MWH battery energy storage, the largest installation of its kind in the State of Colorado.

Summary and Outlook

"Year-to-date results have put us on track to achieve record results in 2022 and provide the foundation for our continued progress in 2023 and beyond. We see high energy prices, together with customer demand for both resilience and cost savings, and the recently enacted Inflation Reduction Act (IRA) as long-term growth catalysts for Ameresco. These factors strengthen our ability to achieve our 2024 Adjusted EBITDA target of $300 million and continue our growth trajectory in the years ahead." Mr. Sakellaris noted.

"We are pleased to reiterate our 2022 guidance. During 2022, we anticipate placing between 50 and 70 MWe of energy assets in service, while investing approximately $225 million to $275 million of capital, the majority of which we expect to fund with non-recourse debt.

We look forward to welcoming analysts and institutional investors on November 15, 2022 for a tour of our Phoenix, AZ RNG facility showcasing the largest wastewater treatment biogas-to-renewable natural gas facility in the US. We look forward to hosting the plant tour followed by a presentation to provide a deeper understanding of Ameresco's RNG business." Mr. Sakellaris concluded.

FY 2022 Guidance Ranges
Revenue	$1.83 billion	$1.87 billion
Gross Margin	15.5%	16.5%
Adjusted EBITDA	$200 million	$210 million
Interest Expense & Other	$25 million	$27 million

(1) Although net income is the most directly comparable GAAP measure, this table reconciles adjusted EBITDA to operating income because we are not able to calculate forward-looking net income without unreasonable efforts due to significant uncertainties with respect to the impact of accounting for our redeemable non-controlling interests and taxes.

Exhibit A: Non-GAAP Financial Measures

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.

Adjusted EBITDA and Adjusted EBITDA Margin

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-controlling interests, restructuring and asset impairment charges. We define adjusted EBITDA margin as adjusted EBITDA stated as a percentage of revenue.

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.

Non-GAAP Net Income and EPS

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, contingent consideration expense, 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.

Adjusted Cash from 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.
