1. BASIS OF PRESENTATION
The accompanying condensed consolidated financial statements of Ameresco, Inc. (including its subsidiaries, the “Company,” “Ameresco,” “we,” “our,” or “us”) are unaudited, according to certain rules and regulations of the Securities and Exchange Commission, and include, in our opinion, normal recurring adjustments necessary for a fair presentation in conformity with accounting principles generally accepted in the United States (“GAAP”) of the results for the periods indicated.
The results of operations for the three months ended March 31, 2021 are not necessarily indicative of results which may be expected for the full year. The December 31, 2020 consolidated balance sheet data was derived from audited financial statements, but certain information and footnote disclosures normally included in consolidated financial statements prepared in accordance with GAAP have been condensed or omitted. The interim condensed consolidated financial statements and accompanying notes should be read in conjunction with the audited consolidated financial statements and accompanying notes for the year ended December 31, 2020, included in our annual report on Form 10-K (“2020 Annual Report” or “2020 Form 10-K”) for the year ended December 31, 2020 filed with the Securities and Exchange Commission on March 2, 2021.
Reclassification
Certain prior period amounts were reclassified to conform to the presentation in the current period.
Significant Risks and Uncertainties
We considered the impact of COVID-19 on the assumptions and estimates used and determined that there was no material adverse impact on our results of operations for the three months ended March 31, 2021 or 2020. Our results of future operations and liquidity could be adversely impacted by a number of factors associated with the COVID-19 pandemic, including payments of outstanding receivable amounts beyond normal payment terms, delays in obtaining signed customer contracts for awarded projects, supply chain disruptions and uncertain demand. As of the date of issuance of these condensed consolidated financial statements, the extent to which the COVID-19 pandemic may impact our financial condition, liquidity, or results of operations in the future is uncertain.
2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
Our accounting policies are set forth in Note 2 to the consolidated financial statements contained in our 2020 Form 10-K. We have included certain updates to those policies below.
Accounts Receivable and Allowance for Credit Losses
Changes in the allowance for credit losses are as follows:
March 31, 2021March 31, 2020
Allowance for credit losses, beginning of period$2,266 $2,260 
Charges to costs and expenses, net49 
Account write-offs and other41 (189)
Allowance for credit losses, end of period$2,310 $2,120 

Recent Accounting Pronouncements
Income Taxes
In December 2019, the FASB issued ASU No. 2019-12, Simplifying the Accounting for Income Taxes, which simplifies the accounting for income taxes, eliminates certain exceptions within ASC 740, Income Taxes, and clarifies certain aspects of the current guidance to promote consistency among reporting entities. ASU 2019-12 is effective for our fiscal year beginning after December 15, 2020. We adopted this guidance as of January 1, 2021 and the adoption did not have an impact on our condensed consolidated financial statements.
Reference Rate Reform
In March 2020, the FASB issued ASU 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting. ASU 2020-04, which provides optional guidance for a limited period of time to ease the potential

burden in accounting for (or recognizing the effects of) reference rate reform on financial reporting. Companies can apply the ASU immediately, however, the guidance will only be available until December 31, 2022. We are currently evaluating the impact that adopting this new accounting standard would have on our condensed consolidated financial statements and related disclosures.
In January 2021, the FASB issued ASU 2021-01, Reference Rate Reform (Topic 848): Scope. The amendments in ASU 2021-01 provide optional expedients to the current guidance on contract modification and hedge accounting from the expected market transition from LIBOR and other interbank offered rates to alternative reference rates. The guidance generally can be applied to applicable contract modifications through December 31, 2022. We are currently evaluating the impact that adopting this new accounting standard would have on our condensed consolidated financial statements and related disclosures.
Codification Improvements
In October 2020, the FASB issued ASU 2020-10 Codification Improvements. The amendments in this ASU represent changes to clarify the Accounting Standard Codifications, correct unintended application of guidance, or make minor improvements to the ASC that are not expected to have a significant effect on current accounting practice or create a significant administrative cost to most entities. ASU 2020-10 is effective for annual periods beginning after December 15, 2020 and interim periods within those annual periods, with early adoption permitted. The amendments in this ASU should be applied retrospectively. We adopted this guidance as of January 1, 2021 and the adoption did not have an impact on our condensed consolidated financial statements.
3. REVENUE FROM CONTRACTS WITH CUSTOMERS
Disaggregation of Revenue
Our reportable segments for the three months ended March 31, 2021 are U.S. Regions, U.S. Federal, Canada and Non-Solar Distributed Generation (“Non-Solar DG”). We changed the structure of our internal organization and our U.S. Regions segment now includes our U.S.-based enterprise energy management services previously included in our “All Other” segment. As a result, previously reported amounts have been restated for comparative purposes.
The following table presents our revenue disaggregated by line of business and reportable segment for the three months ended March 31, 2021:

Total contract liabilities$30,670 $32,178 
(1) Performance obligations are expected to be completed beyond the next twelve months and are included in other liabilities in the condensed consolidated balance sheets.
The decrease in contract assets for the three months ended March 31, 2021 was primarily due to billings of $144,539, offset in part by revenue recognized of approximately $130,297. The decrease in contract liabilities was primarily driven by recognition of revenue as performance obligations were satisfied exceeding increases from the receipt of advance payment from customers, and related billings. For the three months ended March 31, 2021, we recognized revenue of $45,483 that was previously included in the beginning balance of contract liabilities and billed customers $33,081. Changes in contract liabilities are also driven by reclassifications to or from contract assets as a result of timing of customer payments.
The decrease in contract assets for the three months ended March 31, 2020 was primarily due to billings of approximately $151,885, partially offset by revenue recognized of $137,220. The decrease in contract liabilities was primarily driven by

recognition of revenue as performance obligations were satisfied exceeding increases from the receipt of advance payment from customers, and related billings. For the three months ended March 31, 2020, we recognized revenue of $19,928 that was previously included in the beginning balance of contract liabilities, and billed customers $16,377. Changes in contract liabilities are also driven by reclassifications to or from contract assets as a result of timing of customer payments.
Performance Obligations
Our remaining performance obligations (“backlog”) represent the unrecognized revenue value of our contract commitments. At March 31, 2021, we had backlog of $1,914,710 of which approximately 35% is anticipated to be recognized as revenue in the next twelve months. The remaining performance obligations primarily relate to the energy efficiency and renewable energy construction projects, including long-term O&M services related to these projects. The long-term services have varying initial contract terms, up to 25 years.
Project Development Costs
Project development costs of $1,559 and $1,543 were included in other long-term assets in the accompanying condensed consolidated balance sheets as of March 31, 2021 and December 31, 2020, respectively. Project development costs of $1,985 and $1,635 were recognized in the condensed consolidated statements of income on projects that converted to customer contracts during the three months ended March 31, 2021 and 2020, respectively.
NaN impairment charges in connection with our capitalized commission costs or project development costs were recorded during the three months ended March 31, 2021 and 2020.

The net present value of this commitment totals $3,000 as of March 31, 2021 and relates to a one-time payment due when specific criteria are met, which we estimate will be during the three months ended September 30, 2021.
Sale-leasebacks
We entered into a fifth amendment dated March 22, 2021 to our August 2018 agreement and increased the maximum funding amount from $150,000 up to $350,000 and extended the end date of the agreement from May 23, 2021 to March 31, 2022. We sold and leased back 1 energy asset for $1,087 in cash under this facility during the three months ended March 31, 2021. As of March 31, 2021, approximately $310,618 remained available under this lending commitment. These transactions are accounted for as failed sales and are classified as long-term financing facilities. See Note 7 for additional information.
Net gains from amortization expense in cost of revenues related to deferred gains and losses in connection with our sale-leaseback agreements were $57 and $55 for the three months ended March 31, 2021 and 2020, respectively.

Senior Secured Revolving Credit Facility
We repaid in full the outstanding balances under our senior secured revolving credit facility. See Note 14 for additional information.
October 2020 Term Loan Modification
In October 2020, we entered into an amended and restated credit agreement with a bank primarily to increase the commitments under the existing credit agreement and add projects eligible for financing. The new credit agreement increased the commitment from $28,500 to $35,000 and included an option for the lender to increase the commitment by up to an additional $15,000 for a total not to exceed $50,000.
During the three months ended March 31, 2021, the lender increased its commitment by the remaining $15,000 and we received net proceeds of $14,848. The quarterly payments consist of $1,250 in principal plus an additional principal prepayment based on project cash flows in addition to interest to be paid through the earlier of maturity, March 2026, or when the principal balance is paid in full. We accounted for this amendment as a modification and at closing we incurred $150 in lender’s fees which were reflected as debt discount and $2 in third-party fees which were expensed in selling, general and administrative expenses during the three months ended March 31, 2021. The unamortized discount and debt issuance costs from the October 2020 loan modification are being amortized over the remaining term of the agreement. The balance of the loan outstanding as of March 31, 2021 was $48,547, net of unamortized discount and debt issuance costs.
June 2020 Construction Revolver
In June 2020, we entered into a revolving credit agreement with a bank, with an aggregate borrowing capacity of $100,000 for use in financing the construction cost of our owned projects. In March 2021, we entered into a third amendment to this agreement to extend this facility from May 2021 to March 2022. All remaining unpaid amounts outstanding under the facility are due at that time.
During the three months ended March 31, 2021, we closed on $14,013 in funding for 4 additional projects under this facility and drew down an additional $711 for an existing project. The balance of this construction revolver as of March 31, 2021 was $29,460, net of unamortized debt issuance costs and funds of $70,099 are available for borrowing under this facility.

8. INCOME TAXES
We recorded a provision (benefit) for income taxes of $2,205 and $(2,503) for the three months ended March 31, 2021 and 2020, respectively. The estimated effective annualized tax rate impacted by the period discrete items is 15.1% for the three months ended March 31, 2021, compared to a (60.6)% of estimated effective annualized tax rate for the three months ended March 31, 2020.
The principal reasons for the difference between the statutory rate and the estimated annual effective rate for 2021 were the effects of investment tax credits which we are entitled from solar plants placed into service or are forecasted to be placed into service during 2021, the tax deductions related to the Section 179D deduction, the deduction of compensation expense associated with certain employee stock options, and tax basis adjustments on certain partnership flip transactions.
The principal reason for the difference between the statutory rate and the estimated annual effective rate for 2020 were the effects of investment tax credits to which we are entitled from solar plants which were placed into service during 2020, tax deductions related to the Section 179D deduction, tax basis adjustments on certain partnership flip transactions, and tax rate benefits associated with the net operating loss carryback made possible by the passing of the COVID-19 CARES Act on March 27, 2020.
The following table sets forth the total amounts of gross unrecognized tax benefits:
Gross Unrecognized
Tax Benefits
Balance, December 31, 2020$600 
Balance, March 31, 2021$600 
The amount of unrecognized tax benefits that, if recognized, would favorably affect the effective income tax rate in any future periods was $190 as of March 31, 2021 and December 31, 2020 (net of the federal benefit on state amounts).
We presented all deferred tax assets and liabilities as noncurrent, net liabilities on our condensed consolidated balance sheets as of March 31, 2021, and December 31, 2020.
9. COMMITMENTS AND CONTINGENCIES
From time to time, we issue letters of credit and performance bonds with our third-party lenders, to provide collateral.
Legal Proceedings
On November 6, 2017, we were served with a complaint filed by a customer against 9 contractors, including us, claiming both physical damages to the customer’s tangible property and damages caused by various alleged defects in the design of the project through negligent acts and/or omissions, breaches of contract and breaches of the “implied warranty of good and workmanlike manner.” A mediation was held in January 2021, at which time we made an offer to settle the case, in an amount which we believe would be covered by our insurance. Although the customer rejected our offer, both parties have agreed to continue to negotiate a settlement. We believe that it is probable that a loss will be incurred and, therefore, have accrued a reasonable estimate of the loss, which is included in accrued expenses and other current liabilities in our consolidated balance sheets as of December 31, 2020 and March 31, 2021. In addition, we accrued a loss recovery from insurance proceeds as we believe the receipt of such proceeds is probable. The loss recovery accrual is included in prepaid expenses and other current assets in our consolidated balance sheets as of December 31, 2020 and March 31, 2021. There were no changes to our estimate during the three months ended March 31, 2021.
We are involved in a variety of other claims and other legal proceedings generally incidental to our normal business activities. While the outcome of any of these proceedings cannot be accurately predicted, we do not believe the ultimate resolution of any of these existing matters would have a material adverse effect on our financial condition or results of operations.
Commitment as a Result of an Acquisition
In August 2018, we completed an acquisition which provided for a revenue earn-out contingent upon the acquired business meeting certain cumulative revenue targets over 5 years from the acquisition date. The fair value was $678 as of March 31, 2021 and December 31, 2020 and is included in other liabilities on the condensed consolidated balance sheets. The contingent

consideration will be paid annually in May, if any of the cumulative revenue targets are achieved. NaN payments have been made to date.
10. FAIR VALUE MEASUREMENT
We recognize our financial assets and liabilities at fair value on a recurring basis (at least annually). Fair value is defined as the price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Three levels of inputs that may be used to measure fair value are as follows:
Level 1: Inputs are based on unadjusted quoted prices for identical instruments traded in active markets. 
Level 2: Inputs are based on quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active, and model-based valuation techniques for which all significant assumptions are observable in the market or can be corroborated by observable market data for substantially the full term of the assets or liabilities. 
Level 3: Inputs are generally unobservable and typically reflect management’s estimates of assumptions that market participants would use in pricing the asset or liability. The fair values are therefore determined using model-based techniques that include option pricing models, discounted cash flow models, and similar techniques. 
The following table presents the input level used to determine the fair values of our financial instruments measured at fair value on a recurring basis:
Fair Value as of
LevelMarch 31, 2021December 31, 2020

Make-whole provisions21,112 412 
Contingent consideration3678 678 
Total liabilities$8,992 $11,163 
The fair value of our long-term debt was estimated using discounted cash flows analysis, based on our current incremental borrowing rates for similar types of borrowing arrangements which are considered to be level two inputs. There have been no transfers in or out of level two or three financial instruments for the three months ended March 31, 2021 and the year ended December 31, 2020.
The following table sets forth the fair value and the carrying value of our long-term debt, excluding financing leases:

Fair ValueCarrying ValueFair ValueCarrying Value
Long-term debt (Level 2)$320,279 $316,709 $363,460 $357,536 
We are also required to periodically measure certain other assets at fair value on a nonrecurring basis, including long-lived assets, goodwill and other intangible assets. We calculated the fair value used in our annual goodwill impairment analysis utilizing a discounted cash flow analysis and determined that the inputs used were level 3 inputs. There were no assets recorded at fair value on a non-recurring basis as of March 31, 2021 or December 31, 2020.

13. REDEEMABLE NON-CONTROLLING INTERESTS
Our subsidiaries with membership interests in the investment funds we formed have the right to elect to require the non-controlling interest holder to sell all of its membership units to our subsidiaries, a call option. Our investment funds also include rights for the non-controlling interest holder to elect to require our subsidiaries to purchase all of the non-controlling membership interests in the fund, a put option.
The call options are exercisable beginning on the date that specified conditions are met for each respective fund. The call option period for one of our investment funds began in March 2021. The put options for the investment funds are exercisable beginning on the date that specified conditions are met for each respective fund.
We initially record our redeemable non-controlling interests at fair value on the date of acquisition and subsequently adjust to redemption value. At both March 31, 2021 and December 31, 2020 redeemable non-controlling interests were reported at their carrying values, as the carrying value at each reporting period was greater than the estimated redemption value.

14. EQUITY AND EARNINGS PER SHARE
Equity Offering
On March 9, 2021, we closed on an underwritten public offering of 2,500 shares of our Class A common stock at a public offering price of $44.00 per share. Net proceeds from the offering were $104,458, after deducting offering costs of $5,542. On March 15, 2021, we closed on the underwriters’ option to purchase 375 additional shares of Class A common stock from us, resulting in net proceeds of $15,758 after deducting offering costs of $742. We used $80,000 of the net proceeds to repay in full the outstanding U.S. dollar balance under our senior secured revolving credit facility.
In the offering, selling shareholders sold 805 shares our Class A Common Stock at a public offering price of $44.00 per share, less the underwriting discount. We did 0t receive any proceeds from the sale of the shares by the selling stockholders.

During the three months ended March 31, 2021, we granted 694 common stock options to certain employees under our 2020 Stock Incentive Plan, which have a contractual life of ten years and vest over a five-year period. We did not grant awards to individuals who were not either an employee or director of ours during the three months ended March 31, 2021 or during the year ended December 31, 2020.
16. BUSINESS SEGMENT INFORMATION
Our reportable segments for the three months ended March 31, 2021 are U.S. Regions, U.S. Federal, Canada and Non-Solar Distributed Generation (“Non-Solar DG”). We changed the structure of our internal organization and our U.S. Regions segment now includes our U.S.-based enterprise energy management services previously included in our “All Other” segment. As a result, previously reported amounts have been restated for comparative purposes.
Our U.S. Regions, U.S. Federal and Canada segments offer energy efficiency products and services which include the design, engineering and installation of equipment and other measures to improve the efficiency and control the operation of a facility’s energy infrastructure, renewable energy solutions and services and the development and construction of small-scale plants that Ameresco owns or develops for customers that produce electricity, gas, heat or cooling from renewable sources of energy and O&M services.
Our Non-Solar DG segment sells electricity, processed renewable gas fuel, heat or cooling, produced from renewable sources of energy, other than solar, and generated by small-scale plants that we own and O&M services for customer-owned small-scale plants.
The “All Other” category includes enterprise energy management services, other than the U.S.-based portion; consulting services, energy efficiency products and services outside of the U.S. and Canada; and the sale of solar PV energy products and systems which we refer to as integrated-PV.
These segments do not include results of other activities, such as corporate operating expenses not specifically allocated to the segments. Certain reportable segments are an aggregation of operating segments.
The accounting policies are the same as those described in the summary of significant accounting policies in Note 2 included in our 2020 Form 10-K.

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations
You should read the following discussion and analysis of our financial condition and results of operations together with our unaudited condensed consolidated financial statements and the related notes thereto included in Part I, Item 1 of this Quarterly Report on Form 10-Q and the audited consolidated financial statements and notes thereto and management’s discussion and analysis of financial condition and results of operations for the year ended December 31, 2020 included in our Annual Report on Form 10-K (“2020 Annual Report”) for the year ended December 31, 2020 filed on March 2, 2021 with the U.S. Securities and Exchange Commission (“SEC”). This Quarterly Report on Form 10-Q contains “forward-looking statements” within the meaning of Section 21E of the Securities Exchange Act of 1934, as amended, or the Exchange Act. Forward looking statements include statements regarding our strategy, future operations, future financial position, future revenues, projected costs, prospects, plans, objectives of management, expected market growth and other characterizations of future events or circumstances. All statements, other than statements of historical fact, including statements that refer to our expectations as to the future growth of our business and associated expenses; our expectations as to revenue generation; the future availability of borrowings under our revolving credit facility; the expected future growth of the market for energy efficiency and renewable energy solutions; our backlog, awarded projects and recurring revenue and the timing of such matters; our expectations as to acquisition activity; the impact of any restructuring; the uses of future earnings; our intention to repurchase shares of our Class A common stock; the expected energy and cost savings of our projects; and the expected energy production capacity of our renewable energy plants; the results of the SEC’s investigation into our revenue recognition and compensation practices in our software-as-a-service businesses; and other characterizations of future events or circumstances are forward-looking statements. Currently, one of the most significant factors, however, is the potential adverse effect of the current pandemic of the novel coronavirus, or COVID-19, on our financial condition, results of operations, cash flows and performance and the global economy and financial markets. The extent to which COVID-19 impacts us, suppliers, customers, employees and supply chains will depend on future developments, which are highly uncertain and cannot be predicted with confidence, including the scope, severity and duration of the pandemic, the actions taken to contain the pandemic or mitigate its impact, and the direct and indirect economic effects of the pandemic and containment measures, among others. Moreover, you should interpret many of the risks identified in this report, as well as the risks set forth below, as being heightened as a result of the ongoing and numerous adverse impacts of COVID-19. Forward looking statements are often, but not exclusively, identified by the use of words such as “may,” “will,” “expect,” “believe,” “anticipate,” “intend,” “could,” “estimate,” “target,” “project,” “predict” or “continue,” and similar expressions or variations. These forward-looking statements are based on current expectations and assumptions that are subject to risks, uncertainties and other factors that could cause actual results and the timing of certain events to differ materially and adversely from future results expressed or implied by such forward-looking statements. Risks, uncertainties and factors that could cause or contribute to such differences include, but are not limited to, those discussed in the section titled “Risk Factors,” set forth in Item 1A of our 2020 Annual Report. The forward-looking statements in this Quarterly Report on Form 10-Q represent our views as of the date of this Quarterly Report on Form 10-Q. Subsequent events and developments may cause our views to change. However, while we may elect to update these forward-looking statements at some point in the future, we have no current intention of doing so and undertake no obligation to do so except to the extent required by applicable law. You should, therefore, not rely on these forward-looking statements as representing our views as of any date subsequent to the date of this Quarterly Report on Form 10-Q.

Overview
Ameresco is a leading clean technology integrator with a comprehensive portfolio of energy efficiency and renewable energy supply solutions. We help organizations meet energy savings and energy management challenges with an integrated comprehensive approach to energy efficiency and renewable energy. Leveraging budget neutral solutions, including ESPCs and power purchase agreements, we aim to eliminate the financial barriers that traditionally hamper energy efficiency and renewable energy projects.
Drawing from decades of experience, Ameresco develops tailored energy management projects for its customers in the commercial, industrial, local, state and federal government, K-12 education, higher education, healthcare and public housing sectors.
We provide solutions primarily throughout North America and the U.K. and our revenues are derived principally from energy efficiency projects, which entail the design, engineering and installation of equipment and other measures that incorporate a range of innovative technology and techniques to improve the efficiency and control the operation of a facility’s energy infrastructure; this can include designing and constructing a central plant or cogeneration system for a customer providing power, heat and/or cooling to a building, or other small-scale plant that produces electricity, gas, heat or cooling from renewable sources of energy. We also derive revenue from long-term O&M contracts, energy supply contracts for renewable energy operating assets that we own, integrated-PV, and consulting and enterprise energy management services.
In addition to organic growth, strategic acquisitions of complementary businesses and assets have been an important part of our growth enabling us to broaden our service offerings and expand our geographical reach.

Key Factors and Trends
COVID-19 Update
Fiscal year 2020 was marked with unrivaled global challenges, including the public health and economic downturn caused by the COVID-19 pandemic. During the first half of 2020, after COVID-19 was declared a pandemic by the World Health Organization, we experienced some delays in our project award conversions and some construction slowdowns due to shelter-in-place restrictions, however, the opportunities to reduce emissions and limit the effects of climate change remained. We responded to the pandemic by ensuring the health and safety of our employees. We implemented a seamless transition to remote operations for many months, and, while following all CDC guidelines, continued front-line work at our essential facilities and the impact to our results of operations and liquidity for the year ended December 31, 2020 was not material.
Further, the overall impact of COVID-19 on our condensed consolidated results of operations for the three months ended March 31, 2021 was not material. However, the impact to our future results remains uncertain and will depend on a number of factors, including, but not limited to, the duration and severity of the pandemic and its impact on our customers. We will continue to evaluate the nature and extent of these potential impacts to our business, consolidated results of operations, segment results, liquidity and capital resources.
The Energy Act of 2020
On December 27, 2020, the President signed the Consolidated Appropriations Act, 2021 into law, a legislative package that included the Energy Act of 2020, reauthorizing a number of U.S. Department of Energy programs, with a $2.3 trillion spending bill containing appropriations for fiscal year 2021, COVID-19 relief funds, and extensions of a number of expiring tax incentives important to the energy sector. It includes $35 billion in energy research and development programs, a two-year extension of the 26% Investment Tax Credit (“ITC”) rate for solar power that will retain the current 26% credits for solar projects that begin construction through the end of 2022. The 26% rate for ITC for solar projects was set to expire at the end of 2020. The Energy Act of 2020 also made the Section 179D Energy Efficient Commercial Building Deduction permanent under the tax code.
The Coronavirus Aid, Relief, and Economic Security Act (“CARES Act”)
On March 27, 2020, the U.S. government enacted the CARES Act which includes modifications to the limitation on business interest expense and net operating loss provisions, and provides a payment delay of employer payroll taxes during 2020 after the date of enactment. The payment of $4.5 million of employer payroll taxes otherwise due in 2020 has been delayed with 50% due by December 31, 2021 and the remaining 50% by December 31, 2022. The CARES Act permits net operating losses from the 2018, 2019, and 2020 tax years to be carried back to the previous five tax years (beginning with the earliest year first). During the three months ended March 31, 2021, we received approximately $4.0 million in federal income tax refunds as a result of the carryback provisions of the CARES Act and our ability to utilize Alternative Minimum Tax Credits.
Effects of Seasonality
We are subject to seasonal fluctuations and construction cycles, particularly in climates that experience colder weather during the winter months, such as the northern United States and Canada, or at educational institutions, where large projects are typically carried out during summer months when their facilities are unoccupied. In addition, government customers, many of which have fiscal years that do not coincide with ours, typically follow annual procurement cycles and appropriate funds on a fiscal-year basis even though contract performance may take more than one year. Further, government contracting cycles can be affected by the timing of, and delays in, the legislative process related to government programs and incentives that help drive demand for energy efficiency and renewable energy projects. As a result, our revenues and operating income in the third and fourth quarter are typically higher, and our revenues and operating income in the first quarter are typically lower, than in other quarters of the year. As a result of such fluctuations, we may occasionally experience declines in revenues or earnings as compared to the immediately preceding quarter, and comparisons of our operating results on a period-to-period basis may not be meaningful.
Our annual and quarterly financial results are also subject to significant fluctuations as a result of other factors, many of which are outside our control. See “Our business is affected by seasonal trends and construction cycles, and these trends and cycles could have an adverse effect on our operating results.” in Item 1A, Risk Factors of our 2020 Annual Report.
Stock-based Compensation
During the three months ended March 31, 2021, we granted 693,500 common stock options to certain employees under our 2020 Stock Incentive Plan. As a result our unrecognized stock-based compensation expense increased from $12.1 million at December 31, 2020 to $26.1 million at March 31, 2021 and we anticipate our stock-based compensation expense to increase over the next three years.

Backlog and Awarded Projects
The following table presents our backlog:
As of March 31,
(In Thousands)20212020
Project Backlog
Fully-contracted backlog$787,815 $1,049,915 
Awarded, not yet signed customer contracts1,521,160 1,130,300 
Total project backlog$2,308,975 $2,180,215 
12-month project backlog$607,000 $514,440 
O&M Backlog
Fully-contracted backlog$1,126,895 $1,131,730 
12-month O&M backlog$64,360 $60,490 
Total project backlog represents energy efficiency projects that are active within our sales cycle. Our sales cycle begins with the initial contact with the customer and ends, when successful, with a signed contract, also referred to as fully-contracted backlog. Our sales cycle recently has been averaging 18 to 42 months. Awarded backlog is created when a potential customer awards a project to Ameresco following a request for proposal. Once a project is awarded but not yet contracted, we typically conduct a detailed energy audit to determine the scope of the project as well as identify the savings that may be expected to be generated from upgrading the customer’s energy infrastructure. At this point, we also determine the subcontractor, what equipment will be used, and assist in arranging for third party financing, as applicable. Recently, awarded projects have been taking an average of 12 to 24 months to result in a signed contract and convert to fully-contracted backlog. It may take longer, as it depends on the size and complexity of the project. Historically, approximately 90% of our awarded backlog projects have resulted in a signed contract. After the customer and Ameresco agree to the terms of the contract and the contract becomes executed, the project moves to fully-contracted backlog. The contracts reflected in our fully-contracted backlog typically have a construction period of 12 to 36 months and we typically expect to recognize revenue for such contracts over the same period.
Our O&M backlog represents expected future revenues under signed multi-year customer contracts for the delivery of O&M services, primarily for energy efficiency and renewable energy construction projects completed by us for our customers.
We define our 12-month backlog as the estimated amount of revenues that we expect to recognize in the next twelve months from our fully-contracted backlog. See “We may not recognize all revenues from our backlog or receive all payments anticipated under awarded projects and customer contracts” and “In order to secure contracts for new projects, we typically face a long and variable selling cycle that requires significant resource commitments and requires a long lead time before we realize revenues” in Item 1A, Risk Factors in our 2020 Annual Report.
Assets in Development
Assets in development, which represents the potential design/build project value of small-scale renewable energy plants that have been awarded or for which we have secured development rights, were estimated at $1,103.4 million and $658.6 million as of March 31, 2021 and 2020, respectively.

Our results of operations for the three months ended March 31, 2021 reflect year-over-year growth in terms of revenues, operating income, and net income attributable to common shareholders. Our strong operating results were due to the following:
Revenue: total revenues increased primarily due to a $36.3 million, or 25%, increase in our project revenue attributed to strong execution of our contracted backlog and accelerated timing of certain approvals and progress on customized equipment, and a $5.1 million, or 18%, increase in our energy asset revenue attributed to increased production levels and favorable pricing on renewable identification numbers (“RINs”) generated from certain non-solar distributed generation assets in operation, partially offset by a $2.3 million, or 20%, decrease in our integrated-PV revenue resulting from unfavorable weather conditions.
Cost of Revenues and Gross Profit: the increase in cost of revenues is primarily due to the increase in project revenues described above. The increase in gross profit as a percentage of revenue is primarily due to a higher proportion of higher margin energy asset revenue as part of the revenue mix.
Selling, General and Administrative Expenses: the decrease is primarily due to lower travel expenses of $0.5 million, primarily as a result of continued COVID-19 related restrictions, lower IT and telecommunications of $0.3 million, and lower net salaries and benefits of $0.1 million, partially offset by increases in professional fees of $0.4 and insurance of $0.2 million.
Other Expenses, Net: Other expenses, net, includes gains and losses from derivatives transactions, foreign currency transactions, interest expense, interest income, amortization of deferred financing costs and certain government incentives. Other expenses, net decreased due to lower interest expenses of $1.7 million related to a net $14.7 million decrease in debt as we used a portion of the net proceeds from our equity offering to pay off the revolver balance on our senior secured credit facility.
Income before Income Taxes: the increase is due to reasons described above.
Income Tax Provision (Benefit): the provision for income taxes is based on various rates set by federal, state, provincial and local authorities and is affected by permanent and temporary differences between financial accounting and tax reporting requirements. The effective tax rate was higher in 2021 as compared to 2020 primarily due to generally higher forecasted pretax income in the U.S. in 2021 and the inclusion in 2020 of a discrete tax rate benefit associated with net operating loss carrybacks made possible by the passing of the CARES Act on March 27, 2020.
Net Income and Earnings Per Share: Net income attributable to common shareholders increased due to reasons described above. Basic earnings per share for 2021 was $0.23, an increase of $0.10 per share compared to the same period of 2020. Diluted earnings per share for 2021 was $0.22, an increase of $0.09 per share compared to last year. The equity offering in March 2021 increased the weighted average shares outstanding by approximately 685,000, which did not materially impact earnings per share this quarter. Earnings per share in future quarters, however, may be impacted because the weighted average shares outstanding in those quarters will reflect the full 2,875,000 shares sold.

Business Segment Analysis
Our reportable segments for the three months ended March 31, 2021 are U.S. Regions, U.S. Federal, Canada and Non-Solar Distributed Generation (“Non-Solar DG”). We changed the structure of our internal organization and our U.S. Regions segment now includes our U.S.-based enterprise energy management services previously included in our “All Other” segment. As a result, previously reported amounts have been restated for comparative purposes. These segments do not include results of other activities, such as corporate operating expenses not specifically allocated to the segments. See Note 16 “Business Segment Information” for additional information about our segments.

Total revenues$252,202 $212,413 $39,789 18.7 %
U.S. Regions: the decrease is primarily due to a decrease in project revenues attributable to the timing of revenue recognized as a result of the phase of active projects versus the prior year.
U.S. Federal: the increase is primarily due to an increase in project revenue attributable to the timing of revenue recognized as a result of the phase of active projects which benefited from accelerated timing of certain approvals and progress on customized equipment.
Canada: the increase is primarily due to fluctuations in foreign exchange rates. Excluding the impact of foreign exchange, revenue would have been lower, primarily due to a decrease in project revenues attributable to the timing of revenue recognized as a result of the phase of active projects versus the prior year.
Non-Solar DG: the increase is primarily attributed to increased production levels and favorable pricing on RINs generated from certain non-solar distributed generation assets in operation.
All Other: the decrease is primarily due to a decrease in integrated-PV and other revenues which is a result of weakened sales to our oil and gas customers attributed to unfavorable weather conditions, partially offset by an increase in project revenues related to an increase in volume and progression of certain active projects.

Unallocated corporate activity includes all corporate level selling, general and administrative expenses and other expenses not allocated to the segments. We do not allocate any indirect expenses to the segments. Corporate activity increased primarily due to higher salaries and benefit costs, higher professional fees and increased insurance costs.

Liquidity and Capital Resources
Overview
Since inception, we have funded operations primarily through cash flow from operations, advances from Federal ESPC projects, our senior secured credit facility, and various forms of other debt. In addition, in March 2021, we completed an underwritten public offering of 2,875,000 shares of our Class A Common Stock, for total net proceeds of $120.2 million. See below, Note 7 “Debt and Financing Lease Liabilities”, and Note 14 “Equity and Earnings per Share” for additional information.
Working capital requirements, which can be susceptible to fluctuations during the year due to seasonal demands, generally result from revenue growth, our solar equipment purchase patterns, the timing of funding under various contracts, and payment terms for receivables and payables.
We expect to incur additional expenditures in connection with the following activities:
equity investments, project asset acquisitions and business acquisitions that we may fund time to time
capital investment in current and future energy assets
We regularly monitor and assess our ability to meet funding requirements. We believe that cash and cash equivalents, working capital and availability under our revolving senior secured credit facility, combined with our access to credit markets, will be sufficient to fund our operations through at least May 2022 and thereafter. However, we continue to evaluate and take action, as necessary, to preserve adequate liquidity and ensure that our business can continue to operate during these uncertain times. This may include limiting discretionary spending across the organization and re-prioritizing our capital projects amid the COVID-19 pandemic.
Sources of Liquidity
On March 9, 2021, we closed on an underwritten public offering of 2,500,000 shares of our Class A Common Stock at a public offering price of $44.00 per share. Net proceeds from the offering were $104.5 million, after deducting offering costs. On March 15, 2021, we closed on the underwriters’ option to purchase 375,000 additional shares of Class A common stock from us, resulting in net proceeds of $15.8 million, after deducting offering costs. In the offering, selling shareholders sold 805,000 shares of our Class A Common Stock at a public offering price of $44.00 per share, less the underwriting discount. We did not receive any proceeds from the sale of the shares by the selling stockholders. We used $80.0 million of the net proceeds to repay in full the outstanding U.S. dollar balance under our senior secured revolving credit facility. We intend to use the remaining proceeds for general corporate purposes, including potential tack on acquisitions, working capital and capital expenditures. As of March 31, 2021, we had funds of $101.2 million available under our senior secured revolving credit facility.
During the three months ended March 31, 2021, a lender increased its commitment by the remaining $15.0 million available under a term loan and we received net proceeds of $14.8 million. The quarterly payments consist of $1.25 million in principal plus an additional principal prepayment based on project cash flows in addition to interest to be paid through the earlier of maturity, March 2026, or when the principal balance is paid in full. The balance of this term loan as of March 31, 2021 was $48,547.
During the three months ended March 31, 2021, we also closed on $14.0 million in funding for four additional projects under a construction revolver and drew on an additional $0.7 million for an existing project. The balance of this construction revolver as of March 31, 2021 was $29.5 million and funds of $70.1 million are available for borrowing under this facility.

Our service offering also includes the development, construction, and operation of small-scale renewable energy plants. Small-scale renewable energy projects, or energy assets, can either be developed for the portfolio of assets that we own and operate or designed and built for customers. Expenditures related to projects that we own are recorded as cash outflows from investing activities. Expenditures related to projects that we build for customers are recorded as cash outflows from operating activities as cost of revenues.
Cash Flows from Operating Activities
Our cash flows from operating activities improved from last year primarily due to higher net income of $12.4 million and non-cash items totaling $13.2 million in 2021 compared to $6.6 million and non-cash items totaling $10.2 million in 2020, as well as improved accounts receivable collections. We also received a federal income tax refund of approximately $4.0 million as a result of the CARES Act which permitted us to carry our 2018 operating loss back to previous years and utilize Alternative Minimum Tax Credits. These factors were partially offset by an increase of $66.0 million in Federal ESPC receivables, compared to $39.9 million in 2020, which is consistent with the increase in our U.S. Federal revenues. The Federal ESPC operating cash flows only reflect the ESPC expenditure outflows and do not reflect any inflows from the corresponding contract revenues, which are recorded as cash inflows from financing activities due to the timing of the receipt of cash related to the assignment of the ESPC receivables to the third-party investors.
Cash Flows from Investing Activities
During the three months ended March 31, 2021 we invested $55.8 million in purchases of energy assets compared to $28.5 million in 2020.
We currently plan to invest approximately $165 million to $215 million in additional capital expenditures during the remainder of 2021, principally for the construction or acquisition of new renewable energy plants, the majority of which will be funded with project finance debt.
Cash Flows from Financing Activities
Our primary sources of financing in 2021 were net proceeds from our equity offering of $120.2 million, net proceeds from Federal ESPC projects and energy assets of $33.5 million and net proceeds from long-term debt financings of $30.8 million, partially offset by net payments on our senior secured revolving credit facility of $53.1 million and payments on long-term debt of $19.1 million.
Our primary sources of financing in 2020 were proceeds received from Federal ESPC projects and energy assets of $62.7 million, net proceeds from our senior secured credit facility of $31.0 million, partially offset by payments on long-term debt of $12.0 million.
We currently plan additional project financings of approximately $120 million to $170 million during the remainder of 2021 to fund the construction or the acquisition of new renewable energy plants as discussed above.
We may also, from time to time, finance our operations through issuance or offering of equity or debt securities.
Critical Accounting Policies and Estimates
Preparing our consolidated financial statements in accordance with GAAP involves us making estimates and assumptions that affect reported amounts of assets and liabilities, net sales and expenses, and related disclosures in the accompanying notes at the date of our financial statements. We base our estimates on historical experience, industry and market trends, and on various other
30

assumptions that we believe to be reasonable under the circumstances. However, by their nature, estimates are subject to various assumptions and uncertainties, and changes in circumstances could cause actual results to differ from these estimates, sometimes materially.
Income Taxes
We have reviewed all tax positions taken as of March 31, 2021 and we believe our current tax reserves are adequate to cover all known tax uncertainties. We are evaluating The American Rescue Plan Act of 2021 passed into law on March 11, 2021 and at this time do not believe it will have a material impact on our accounting for income taxes.
Other than as noted above, there have been no material changes in our critical accounting estimates from those disclosed in Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations of our 2020 Form 10-K. In addition, refer to Note 2 “Summary of Significant Accounting Policies” for updates to critical accounting policies.
Recent Accounting Pronouncements
See Note 2, “Summary of Significant Accounting Policies” for a discussion of recent accounting pronouncements.
Item 3. Quantitative and Qualitative Disclosures About Market Risk
As of March 31, 2021, there have been no significant changes in market risk exposures that materially affected the quantitative and qualitative disclosures as described in Item 7A to our 2020 Annual Report.

Item 4. Controls and Procedures
Evaluation of Disclosure Controls and Procedures
Our management, with the participation of our principal executive officer and principal financial officer, evaluated the effectiveness of our disclosure controls and procedures, as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act, as of the end of the period covered by this quarterly report, or the evaluation date. Disclosure controls and procedures are designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported, within the time periods specified in the SEC’s rules and forms. Our management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving their objectives, and management necessarily applies its judgment in evaluating the cost-benefit relationship of possible controls and procedures. Our management, after evaluating the effectiveness of our disclosure controls and procedures as of the evaluation date, concluded that as of the evaluation date, our disclosure controls and procedures were effective at a reasonable level of assurance.
Changes in Internal Control over Financial Reporting
There were no changes in our internal control over financial reporting during our most recent fiscal quarter that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

PART II - OTHER INFORMATION
Item 1. Legal Proceedings
In the ordinary conduct of our business we are subject to periodic lawsuits, investigations, and claims. Although we cannot predict with certainty the ultimate resolution of such lawsuits, investigations and claims against us, we do not believe that any currently pending or threatened legal proceedings to which we are a party will have a material adverse effect on our business, results of operations or financial condition.
For additional information about certain proceedings, please refer to Note 9, Commitments and Contingencies, to our condensed consolidated financial statements included under Part I, Item 1 of this Quarterly Report on Form 10-Q, which is incorporated into this item by reference.

Item 1A. Risk Factors
As of March 31, 2021, there have been no material changes to the risk factors described in Item 1A to our 2020 Annual Report.

Item 2. Unregistered Sales of Equity and Use of Proceeds
Stock Repurchase Program
We did not repurchase any shares of our common stock under our stock repurchase program authorized by the Board of Directors on April 27, 2016 (the “Repurchase Program”) during the three months ended March 31, 2021.
Under the Repurchase Program, we are authorized to repurchase up to $17.6 million of our Class A common stock. As of March 31, 2021, there were shares having a dollar value of approximately $5.9 million that may yet be purchased under the Repurchase Program.
Stock repurchases may be made from time to time through the open market and privately negotiated transactions. The amount and timing of any share repurchases will depend upon a variety of factors, including the trading price of our Class A common stock, liquidity, securities laws restrictions, other regulatory restrictions, potential alternative uses of capital, and market and economic conditions. The Repurchase Program may be suspended or terminated at any time without prior notice and has no expiration date.
