Ameresco, Inc. (NYSE:AMRC), a leading cleantech integrator specializing in energy efficiency and renewable energy, today announced financial results for the fiscal quarter ended June 30, 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.

CEO George Sakellaris commented, "We had another strong quarter. I'm particularly pleased that our positive momentum continued to build strong growth in project backlog and assets in development, supporting both our 2023 guidance and our longer-term financial targets. Total project backlog increased by 9% sequentially, driven by the addition of $493 million in new awards. Furthermore, we continue to see a considerable year-on-year increase in the dollar value of the projects we are bidding on and winning. We also increased our net assets in development by over 100 MW in the second quarter, the largest quarterly increase in our company's history.

"Battery storage is seeing tremendous growth given the need for greater resiliency, increased grid complexities from the rapid growth of renewables, and the financial benefits of the Inflation Reduction Act (IRA). Ameresco has emerged as a leader in the implementation of battery systems given our deep knowledge of deployable technologies, engineering expertise and supplier relationships as demonstrated by our significant project and asset wins and installations during the quarter. Another positive development during the quarter was the EPA's ruling concerning the final Renewable Fuel Standard (RFS) biofuel targets for 2023 – 2025. The outcome provides long term support to the RNG industry and increases our long-term visibility into this important revenue stream.

"During the quarter we published our third annual ESG report entitled ‘Doing Well by Doing Good'. We are proud that our renewable energy assets and customer projects have delivered a cumulative carbon offset of over 95 million metric tons of carbon dioxide. Looking ahead, Ameresco has set a target of achieving net zero carbon emissions from internal operations for scope 1 and scope 2 emissions by 2040 and has pledged to establish emissions reduction targets through the Science Based Targets initiative by 2025. We were also recognized with the Environmental Initiatives Award by the SEAL Business Sustainability Awards for our floating solar plant at Fort Bragg, which is the largest such installation in the southeast."

Second Quarter Financial Results

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

Total revenue of $327.1 million exceeded the company's guidance for the quarter, with faster than-expected execution on several larger projects. Energy Asset revenue increased 16.5% driven by continued growth in operating assets. O&M revenue increased 9.3% reflecting continued growth in long-term contracts. Other revenue increased 3.5% primarily due to strength in the Company's utility SaaS and consulting business. Gross margin expanded year-on-year while SG&A increased slightly during the quarter to support growth in proposal activity and the integration of Enerqos. Net income attributable to common shareholders and adjusted EBITDA were $6.4 million and $37.4 million, respectively.

Project Highlights:

Reflecting the recent increase in battery storage activity, Ameresco announced that its joint venture with Atura Power was selected to build a 250 MW battery energy storage system, representing part of the largest BESS award in Canadian history. In addition to providing E&C services for the JV, Ameresco will also own 10.1% of the Asset or approximately 25 MW.
Ameresco announced another significant battery storage win with a four site 379 MW project with Middle River Power at its California gas power plants helping to shift midday renewable energy flows to peak evening hours. The work is expected to commence in summer 2023 and reach completion in Q3 of 2024.
Activity in the higher education market remained strong. Ameresco announced a comprehensive, multi-phase solar and energy efficiency project with St. John's College Santa Fe campus. This project will also include a large PV installation, along with 20 EV charging stations.

Asset Highlights

In the Second Quarter of 2023:

Ameresco's Assets in Development ended the quarter at 594 MWe. After subtracting Ameresco's partners' minority interests, Ameresco's owned capacity of Assets in Development at quarter end was 545 MWe.
We increased our net assets in development by 113 MW in the second quarter, the largest quarterly increase in our company's history.

Summary and Outlook

"The Ameresco team delivered strong results that provide confidence in our annual guidance and set the stage for continued growth for years to come. As customers begin to take advantage of the numerous benefits afforded by the IRA, Ameresco, with our deep technical and financial expertise, remains very well positioned to continue to capture additional market share. This momentum together with our rapidly growing Energy Asset business and international opportunities support our long term growth targets," Mr. Sakellaris concluded.

Our 2023 guidance, included in the table below, anticipates adjusted EBITDA growth of 5% at the midpoint.


FY 2023 Guidance Ranges
Revenue	$1.45 billion	$1.55 billion
Gross Margin	19.5%	20.0%
Adjusted EBITDA	$210 million	$220 million
Interest Expense & Other	$30 million	$35 million
Effective Tax Rate	10%	5%
Non-GAAP EPS	$1.80	$1.90

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 estimate third and fourth quarter revenue, adjusted EBITDA and Adjusted EPS to be in the range of:


	Q3 2023 Guidance Ranges		Q4 2023 Guidance Ranges
Revenue	$370 million	$400 million	$550 million	$580 million
Adjusted EBITDA	$50 million	$55 million	$90 million	$100 million
Non-GAAP EPS	$0.45	$0.50	$1.20	$1.25

We expect to place between 80 and 100 MWe of energy assets in service in 2023 including two RNG plants. A third plant we originally anticipated to be placed in service in 2023 is expected to be at mechanical completion by the end of the year, and fully commissioned in Q1 2024. Several additional RNG assets are in the late stages of development and construction, and we continue to expect that 4 or 5 of these will come online during 2024.

Two of the three Southern California Edison projects are currently in commissioning and are expected to achieve substantial completion in Q3. The third project, which was significantly impacted by the heavy rainfall in California, is expected to reach substantial completion in Q4. Based on this timing, we have requested an extension to mid December 2023 to the maturity date of our Delayed Draw Term Loan A under our Sr. Credit Facility.

Non-GAAP Financial Guidance

Adjusted earnings before interest, taxes, depreciation and amortization (adjusted EBITDA):
Year Ended December 31, 2023
	Low	High
Operating income ⁽¹⁾	$132 million	$140 million
Depreciation and amortization	$63 million	$65 million
Stock-based compensation	$16 million	$17 million
Non-controlling interest and other adjustments	$(1) million	$(2) million
Adjusted EBITDA	$210 million	$220 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, 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.
