Ameresco Reports Fourth Quarter and Full Year 2023 Financial Results

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, 2023. 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. All financial result comparisons made are against the prior year period unless otherwise noted.

CEO George Sakellaris commented, “Fourth quarter results represented a strong finish to a challenging year, demonstrating positive momentum that supports Ameresco’s long term growth trajectory. In addition to the considerable revenue and Adjusted EBITDA growth achieved in the quarter, we grew total project backlog nearly 50%, ending 2023 with a record $3.9 billion. We also grew our assets in development 35% to 717 MWe at the end of the year. Both of which provide a pathway for continued growth over the next several years. Despite the industry headwinds, specifically supply chain issues and administrative bottlenecks that caused the push-out of project revenues we noted last quarter, we are pleased to report that we converted and executed on a number of these previously-delayed projects contributing to the 40% increase in our fourth quarter Project revenues. Additionally, we have taken actions to streamline our organization and have considered these industry factors in our future planning and project scheduling. With respect to Energy Assets, we placed 63 MWe into operation in the fourth quarter, bringing our total operating Energy Assets to over 500 MWe.

“We continue to make great strides in growing our UK and European footprint. After a year of strong organic and acquisitive revenue growth of over 150%, this unit now accounts for over 10% of our total revenue. We believe this market remains highly fragmented and very economically attractive to Ameresco.

“Ameresco’s record backlog and asset pipeline metrics underscore the strength of our market positioning and our ability to continue to achieve substantial long-term growth in revenues and profitability. New awards in 2023 were approximately $2.2 billion, double last year’s $1.1 billion, and proposal activity remained at an all-time high. In 2023, our Energy Asset business continued to add high return assets to our development pipeline. During the year, we increased Ameresco-owned Assets in development by 199 MWe to 669 MWe, while also bringing 118 MWe into operation during the year.”

Fourth Quarter Financial Results

(in millions)	4Q 2023			4Q 2022
	Revenue	Net Income (1)	Adj. EBITDA	Revenue	Net Income (1)	Adj. EBITDA
Projects	$346.5	$27.2	$26.3	$247.1	$7.8	$15.5
Energy Assets	$43.9	$1.3	$23.3	$39.1	$7.0	$20.1

(1) Net Income represents net income attributable to common shareholders
(2) Numbers in table may not sum due to rounding.

Total revenue was $441.4 million, a 33% increase, with double-digit growth across all four of our lines of business. Our Projects business experienced 40% revenue growth as the Company executed on a number of large contract conversions, some that had slipped from the previous quarter, and benefited from increased overall activity, including revenues related to the addition of the Enerqos acquisition in Italy earlier in the year. We also saw a benefit of approximately $40 million from faster implementation of active contracts. Energy Asset revenue increased 12.3% driven by continued growth in our operating asset portfolio and stronger RIN prices. O&M revenue was up 13.2% reflecting increased growth in our long-term contracts while Other revenue increased 11.4%. Gross margin of 16.8% declined due to an increase in the mix of larger, lower margin contracts. We continued to take advantage of clean energy tax incentives available under the Inflation Reduction Act, resulting in a larger than expected effective tax rate benefit of (67.0%). Net income attributable to common shareholders was $33.7 million. The GAAP results for 2023 reflect a non-cash downward adjustment of $1.6 million related to energy asset impairment charges and a non-cash downward adjustment of $2.2 million related to a goodwill impairment charge. Adjusted EBITDA increased 33% to $54.9 million. GAAP and Non-GAAP EPS were $0.64 and $0.69, respectively, with Non-GAAP EPS increasing 97%.

Our Energy Asset Debt was $1.2 billion with an Energy Debt Advance rate of 72% on the Energy Asset Book Value. Our Adjusted Cash from Operations in Q4 was $17.5 million and $84.3 million for 2023. Given the volatility of quarterly Adjusted Cash from Operations we are also providing investors with a quarterly average over a trailing 8-quarter period in our supplemental materials, representing our average implementation cycle.

After the end of the year, we announced that we had engaged an investment bank to raise subordinated debt as required by the December 2023 amendment to our Sr. Secured Credit Facility. The debt raise, if successful, would be used to repay outstanding amounts on the Sr. Secured Credit Facility.

• Increased net assets in development by 63 MW in the fourth quarter driven by increased solar and BESS activity.
• Ameresco continued to grow its innovative BESS energy assets under development with the upcoming installation of a 50 MW / 200 MWh system with Silicon Valley Power.
• Ameresco, along with its partner Sunel Group, continued its international business momentum and has begun construction of 300 MW of design-build solar parks across the UK for Sonnedix, a global renewable energy producer.
• The military market continued to show significant interest in installations that provide resiliency to military installations around the world. Ameresco, along with a partner, will install a 6.25 MW solar generation plant funded by the Department of Defense’s Energy Resilience and Conservation Investment Program (ERCIP), which funds projects that improve energy resilience, contribute to mission assurance, save energy and reduce DoD’s energy costs.

Summary and Outlook

“Ameresco’s robust backlog and growing assets in development are strong indicators of how well aligned our capabilities are with market demand. Our broad and deep technical expertise has enabled us to execute on complex projects, positioning us as a leading provider of cost-effective, resilient energy solutions for public and private clients. With over $7 billion in multi-year revenue visibility from our project backlog and asset development pipeline, we have a roadmap to achieving our long-term growth targets.

Ameresco’s full year 2024 guidance is included in the table below and reflects an expected revenue and Adjusted EBITDA growth of 20% and 38%, respectively, at the midpoints. We plan to continue to take advantage of clean energy tax incentives resulting in a likely net tax benefit. The Company expects to place approximately 200 MWe of energy assets in service for all of 2024. Our expected capex for 2024 is $350 million to $400 million, the majority of which we expect to fund with project financing. For the first quarter of fiscal 2024, we expect revenues of $225 million to $275 million and adjusted EBITDA of $20 million to $30 million, with negative non-GAAP EPS. We expect the remainder of the year to follow a more normal quarterly seasonal cadence.

FY 2024 Guidance Ranges
Revenue	$1.60 billion	$1.70 billion
Gross Margin	17.5%	18.5%
Adjusted EBITDA	$210 million	$240 million
Interest Expense & Other	$60 million	$65 million
Non-GAAP EPS	$1.30	$1.50
The Company’s Adjusted EBITDA and Non-GAAP EPS guidance excludes the impact of redeemable non-controlling interest activity, one-time charges, asset impairment charges, changes in contingent consideration, restructuring activities, as well as any related tax impact.

We are working closely with Southern California Edison Company on the final steps toward substantial completion for two of the three projects. Construction activities and preparation for commissioning have begun for the third project, which was significantly impacted by the heavy rainfall in California in 2023. This last site is expected to reach substantial completion in the summer of 2024.

Non-GAAP Financial Guidance
Adjusted earnings before interest, taxes, depreciation and amortization (adjusted EBITDA):
Year Ended December 31, 2024
	Low	High
Operating income (1)	$113 million	$141 million
Depreciation and amortization	$85 million	$86 million
Stock-based compensation	$14 million	$15 million
Restructuring and other charges	$(2) million	$(2) million
Adjusted EBITDA	$210 million	$240 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, goodwill 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, goodwill 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.

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.
