1. BASIS OF PRESENTATION

The accompanying condensed consolidated financial statements of Ameresco, Inc. (including its subsidiaries, the “Company”) are unaudited, pursuant to certain rules and regulations of the Securities and Exchange Commission, and include, in the opinion of the Company, 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 and nine months ended September 30, 2020 are not necessarily indicative of results which may be expected for the full year. The December 31, 2019 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 notes thereto, should be read in conjunction with the audited consolidated financial statements for the year ended December 31, 2019, and notes thereto, included in the Company’s annual report on Form 10-K for the year ended December 31, 2019 filed with the Securities and Exchange Commission on March 4, 2020.

Certain prior period amounts were reclassified or rounded to conform to the presentation in the current period.

Significant Risks and Uncertainties

In March 2020, the World Health Organization categorized Coronavirus Disease 2019 (“COVID-19”) as a pandemic, and the President of the United States declared the COVID-19 outbreak a national emergency.

The Company’s condensed consolidated financial statements reflect estimates and assumptions made by management that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the condensed consolidated financial statements and reported amounts of revenue and expenses during the reporting periods presented. The Company considered the impact of COVID-19 on the assumptions and estimates used and determined that there was no material adverse impact on the Company’s results of operations for the three or nine months ended September 30, 2020.

The severity of the impact of the COVID-19 pandemic on the Company's business will depend on a number of factors, including, but not limited to, the duration and severity of the pandemic and the extent and severity of the impact on the Company's customers, all of which are uncertain and cannot be predicted. The Company's future results of operations and liquidity could be adversely impacted by delays in 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 the Company's financial condition, liquidity, or results of operations is uncertain.

On March 27, 2020, the U.S. government enacted the Coronavirus Aid, Relief, and Economic Security Act (“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 Company estimates the payment of approximately $5,000 of employer payroll taxes otherwise due in 2020 will be 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). The Company estimates the discrete benefit associated with the net operating loss provisions of the CARES Act to be approximately $2,000, an estimated refund of taxes paid in prior years of approximately $1,700, and the carryback also provides an additional refund of approximately $3,600 related to Alternative Minimum Tax credits.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

The accounting policies of the Company are set forth in Note 2 to the consolidated financial statements contained in the Company’s 2019 annual report on Form 10-K. The Company includes herein certain updates to those policies.

Accounts Receivable and allowance for Credit Losses

Accounts receivable are stated at the amount management expects to collect from outstanding balances. Effective January 1, 2020, the Company adopted ASU 2016-13, Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments (ASU 2016-13) prospectively. This ASU replaces the incurred loss impairment model with an expected credit loss impairment model for financial instruments, including trade receivables. The amendment requires entities to consider

forward-looking information to estimate expected credit losses, resulting in earlier recognition of losses for receivables that are current or not yet due, which were not considered under the previous accounting guidance. The Company performed an assessment of its allowance for credit losses and determined that no adjustment was required to retained earnings upon adoption.

The Company’s methodology to estimate the allowance for credit losses includes quarterly assessments of historical bad debt write-off experience, current economic and market conditions, management’s evaluation of outstanding accounts receivable, anticipated recoveries and the Company’s forecasts. Due to the short-term nature of its receivables, the estimate of credit losses is primarily based on aged accounts receivable balances and the financial condition of customers. In addition, specific allowance amounts are established to record the appropriate provision for customers that have a higher probability of default. Bad debts are written off against the allowance when identified. As part of its assessment, the Company also considered the current and expected future economic and market conditions due to the COVID-19 pandemic and determined that the estimate of credit losses was not significantly impacted as of September 30, 2020.

Changes in the allowance for credit losses are as follows:

			September 30, 2020						September 30, 2019
Allowance for credit loss, beginning of period			$	2,260					$	2,765
Recoveries of costs and expenses, net			(1,089)						(134)
Account write-offs and other			(191)						(45)
Allowance for credit loss, end of period			$	980					$	2,586

Recent Accounting Pronouncements

Fair Value Measurement

In August 2018, the FASB issued ASU 2018-13 Fair Value Measurement (Topic 820): Disclosure Framework—Changes to the Disclosure Requirements for Fair Value Measurement, which modifies the disclosure requirements on fair value measurements. ASU 2018-13 was effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. The Company adopted this guidance as of January 1, 2020 and the adoption did not have a material impact on the Company’s condensed consolidated financial statements.

Consolidations

In October 2018, the FASB issued ASU 2018-17, Consolidation (Topic 810), Targeted Improvements to Related Party Guidance for Variable Interest Entities, which aligns the evaluation of whether a decision maker's fee is a variable interest with the guidance in the primary beneficiary test by requiring the decision maker to consider an indirect interest in a VIE held by related party under common control on a proportionate basis. The new standard was effective for interim and annual periods beginning after December 15, 2019, with early adoption permitted. The Company adopted this guidance as of January 1, 2020 and the adoption did not have an impact on the Company’s condensed consolidated financial statements.

Credit Losses

In June 2016, the FASB issued ASU 2016-13, Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments (ASU 2016-13), and a subsequent amendment to the initial guidance, ASU 2018-19 Codification Improvements to Topic 326, Financial Instruments—Credit Losses (collectively, Topic 326). Topic 326 requires measurement and recognition of expected credit losses for financial assets held, which include, but are not limited to, trade and other receivables. The new standard was effective for fiscal years beginning after December 15, 2019. The Company adopted this guidance as of January 1, 2020 and the adoption did not have a material impact on the Company’s condensed consolidated financial statements.

In April 2019, the FASB issued ASU 2019-04, Codification Improvements to Topic 326, Financial Instruments – Credit Losses, Topic 815, Derivatives, and Hedging, and Topic 825, Financial Instruments. The improvements to Topic 815, among other things, clarifies some areas around partial-term fair value hedges, interest rate risk, the amortization of fair value hedge basis adjustments and their disclosure, and some clarification of matters related to the transitioning to ASU 2017-12, which was adopted by the Company during the year ended December 31, 2018. The improvements to Topic 326 clarify certain aspects surrounding accounting for credit losses in connection with the Company’s receivables. These include that the Company should consider anticipated recoveries in its calculation of credit losses. For those that have already adopted ASU No. 2017-12, the new standard

was effective the first annual period beginning after the issuance date of ASU No. 2019-04, or as of January 1, 2020 for the Company, with early adoption permitted. The Company adopted this guidance as of January 1, 2020 and the adoption did not have a material impact on the Company’s condensed consolidated financial statements.

Income Taxes

In December 2019, the FASB issued ASU 2019-12, Simplifying the Accounting for Income Taxes, which 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 the Company for the fiscal year beginning after December 15, 2020. The Company is currently evaluating the impacts of the provisions of ASU 2019-12 on its condensed consolidated financial statements and disclosures.

Others

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 2020-0, 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. The Company is currently evaluating the impact that adopting this new accounting standard will have on its condensed consolidated financial statements and related disclosures.

						September 30, 2019						December 31, 2018
Accounts receivable, net						$	91,755					$	85,985
Accounts receivable retainage, net						$	16,652					$	13,516
Contract Assets:
Costs and estimated earnings in excess of billings						$	124,652					$	86,842
Contract Liabilities:

Accounts receivable retainage represents amounts due from customers, but where payments are withheld contractually until certain construction milestones are met. Amounts retained typically range from 5% to 10% of the total invoice. The Company classifies as a current asset those retainages that are expected to be billed in the next twelve months. Unbilled revenue, presented as costs and estimated earnings in excess of billings, represent amounts earned and billable that were not invoiced at the end of the fiscal period.

Contract assets represent the Company’s rights to consideration in exchange for services transferred to a customer that have not been billed as of the reporting date. The Company’s rights to consideration are generally unconditional at the time its performance obligations are satisfied.

At the inception of a contract, the Company expects the period between when it satisfies its performance obligations, and when the customer pays for the services, will be one year or less. As such, the Company has elected to apply the practical expedient which allows the Company to not adjust the promised amount of consideration for the effects of a significant financing component, when a financing component is present.

When the Company receives consideration, or such consideration is unconditionally due from a customer prior to transferring goods or services to the customer under the terms of a sales contract, the Company records deferred revenue, which represents a contract liability. Such deferred revenue typically results from billings in excess of costs incurred and advanced payments received on project contracts. As of September 30, 2020 and December 31, 2019, the Company classified $4,982 and $5,560, respectively, as a non-current liability, included in other liabilities on the condensed consolidated balance sheets, for those performance obligations expected to be completed beyond the next twelve months.

The decrease in contract assets for the nine months ended September 30, 2020 was primarily due to billings of $464,712, offset in part by revenue recognized of approximately $434,709. The increase in contract liabilities was primarily driven by the receipt of advance payment from customers, and related billings, exceeding reductions from recognition of revenue as performance obligations were satisfied. For the nine months ended September 30, 2020, the Company recognized revenue of $85,356 that was previously included in the beginning balance of contract liabilities and billed customers $86,203. Changes in contract liabilities are also driven by reclassifications to or from contract assets as a result of timing of customer payments.

The increase in contract assets for the nine months ended September 30, 2019 was primarily due to revenue recognized of $317,088, offset in part by billings of approximately $282,568. 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 nine months ended September 30, 2019, the Company recognized revenue of $92,685 that was previously included in the beginning balance of contract liabilities, and billed customers $92,427. Changes in contract liabilities are also driven by reclassifications to or from contract assets as a result of timing of customer payments.

Contracts are often modified for a change in scope or other requirements. The Company considers contract modifications to exist when the modification either creates new or changes the existing enforceable rights and obligations. Most of the Company’s contract modifications are for goods or services that are not distinct from the existing performance obligations.  The effect of a contract modification on the transaction price, and the measure of progress for the performance obligation to which it relates, is recognized as an adjustment to revenue (either as an increase or decrease) on a cumulative catchup basis.

Performance Obligations

A performance obligation is a promise in a contract to transfer a distinct good or service to the customer. Performance obligations are satisfied at a point in time or over time and are supported by contracts with customers. For most of the Company’s contracts, there are multiple promises of goods or services. Typically, the Company provides a significant service of integrating a complex set of tasks and components such as design, engineering, construction management, and equipment procurement for a project

contract. The bundle of goods and services are provided to deliver one output for which the customer has contracted. In these cases, the Company considers the bundle of goods and services to be a single performance obligation. The Company may also promise to provide distinct goods or services within a contract, such as a project contract for installation of energy conservation measures and post-installation O&M services. In these cases the Company separates the contract into more than one performance obligation. If a contract is separated into more than one performance obligation, the Company allocates the total transaction price to each performance obligation in an amount based on the estimated relative standalone selling prices of the promised goods or services underlying each performance obligation.

Backlog

The Company’s remaining performance obligations (hereafter referred to as “backlog”) represent the unrecognized revenue value of the Company’s contract commitments. The Company’s backlog may vary significantly each reporting period based on the timing of major new contract commitments and the backlog may fluctuate with currency movements. In addition, our customers have the right, under some circumstances, to terminate contracts or defer the timing of the Company’s services and their payments to the Company. At September 30, 2020, the Company had backlog of $2,154,526 of which approximately 31% is anticipated to be recognized as revenue in the next twelve months and the remaining, thereafter.

The Company applied the practical expedient for certain revenue streams to exclude the value of remaining performance obligations for (i) contracts with an original expected term of one year or less, or (ii) contracts for which the Company recognizes revenue in proportion to the amount it has the right to invoice for services performed.

Contract Acquisition Costs

The Company accounts for certain acquisition costs over the life of the contract, consisting primarily of commissions when paid. Commission costs are incurred commencing at contract signing. Commission costs are allocated across all performance obligations and deferred and amortized over the contract term on a progress toward completion basis.

As of September 30, 2020 and December 31, 2019, $1,735 of capitalized commission costs related to contracts that were not completed were included in other assets in the accompanying condensed consolidated balance sheets. For contracts that have a duration of less than one year, the Company follows a practical expedient and expenses these costs when incurred. During the three and nine months ended September 30, 2020 and 2019, the amortization of commission costs related to contracts was not material and was included in the accompanying condensed consolidated statements of income.

The Company capitalizes costs incurred related to the development of projects prior to contract signing as it is partial fulfillment of its performance obligations. Capitalized project development costs include only those costs incurred in connection with the development of energy projects, primarily direct labor, interest costs, outside contractor services, consulting fees, legal fees and travel, if incurred after a point in time where the realization of related revenue becomes probable. Project development costs incurred prior to the probable realization of revenue are expensed as incurred. The Company classifies as a current asset those project development costs that are expected to proceed to construction activity in the twelve months that follow. The Company periodically reviews these balances and writes off any amounts where the realization of the related revenue is no longer probable. Project development costs of $1,228 and $1,080 were included in other long-term assets in the accompanying condensed consolidated balance sheets as of September 30, 2020 and December 31, 2019, respectively. During the three months ended September 30, 2020 and 2019, $3,611 and $2,048, respectively, of project development costs were recognized in the condensed consolidated statements of income on projects that converted to customer contracts. During the nine months ended September 30, 2020 and 2019, $9,546 and $13,081, respectively, of project development costs were recognized in the condensed consolidated statements of income on projects that converted to customer contracts.

No impairment charges in connection with the Company’s commission costs or project development costs were recorded during the nine months ended September 30, 2020 and 2019.

4. BUSINESS ACQUISITIONS AND RELATED TRANSACTIONS

The Company accounts for acquisitions using the acquisition method in accordance with ASC 805, Business Combinations. The purchase price for each is allocated to the net assets based on their estimated fair values at the date of each acquisition. The excess purchase price over the estimated fair value of net assets acquired, which are calculated using level 3 inputs per the fair value hierarchy as defined in Note 10, are recorded as goodwill. Intangible assets, if identified, are recorded and are amortized over periods ranging from one to fifteen years. See Note 5 for additional information.

Balance, September 30, 2020			$	—					$	—					$	(1,016)					$	—					$	—					$	(1,016)

The Company performs its annual goodwill impairment testing in the fourth quarter of each year, or more frequently if an event occurs or circumstances change that would more-likely-than-not reduce the fair value of a reporting unit below its carrying amount. During the Company’s annual goodwill impairment testing in 2019, all reporting units had fair values that exceeded their carrying values by at least 15%. If the Company believes that one or more indicators of impairment have occurred, then the Company will perform an impairment test. The Company has the option to perform a qualitative assessment (commonly referred to as “step zero” test) to determine whether further quantitative analysis for impairment of goodwill and indefinite-lived intangible assets is necessary. The qualitative assessment includes a review of macroeconomic conditions, industry and market considerations, internal cost factors, and the Company’s own overall financial and share price performance, among other factors. If, after assessing the totality of events or circumstances the Company determines that it is not more-likely-than-not that the fair value of a reporting unit is less than its carrying amount, the Company does not need to perform a quantitative analysis. Upon assessment, the Company concluded it was not more likely than not that the fair value of the reporting units were less than the carrying value of the reporting units as of September 30, 2020. The Company will monitor future results and will perform a test if indicators trigger an impairment review. At this time, the Company has not deemed the impact that the current macroeconomic environment surrounding the COVID-19 pandemic has or is expected to have on the business to be a triggering event for impairment purposes.

Separable intangible assets that are not deemed to have indefinite lives are amortized over their useful lives. The Company annually assesses whether a change in the life over which the Company’s assets are amortized is necessary, or more frequently if events or circumstances warrant.

Acquired intangible assets other than goodwill that are subject to amortization include customer contracts, customer relationships, non-compete agreements, technology and trade names. Customer contracts are amortized ratably over the period of the acquired customer contracts ranging in periods from approximately one to five years. All other acquired intangible assets are amortized over periods ranging from approximately four to fifteen years, as determined by the nature of the respective intangible asset. The Company did not complete any acquisitions nor acquire any intangible assets during the nine months ended September 30, 2020.

The Company evaluates long-lived assets for impairment as events or changes in circumstances indicate the carrying value of these assets may not be fully recoverable. Examples of such triggering events applicable to our assets include a significant decrease in the market price of a long-lived asset or asset group or a current-period operating or cash flow loss combined with a history of operating or cash flow losses or a projection or forecast that demonstrates continuing losses associated with the use of a long-lived asset or asset group. The Company performs its annual long-lived asset impairment testing in the fourth quarter of each year. In addition to the annual impairment test, the Company regularly assesses whether a triggering event has occurred which would require interim impairment testing.

During the three months ended September 30, 2020, the Company performed an engine overhaul on one of its energy assets, however, the engine consistently failed to achieve emissions compliance and the Company considered the engine unsalvageable. As a result of this event, the Company performed an impairment analysis on this energy asset group and recorded an impairment charge of $1,028, which fully impaired this asset group. The impairment charge is included in selling, general and administrative expenses within the condensed consolidated statements of income for the three and nine months ended September 30, 2020.

The Company assessed the impact that the current macroeconomic environment surrounding the COVID-19 pandemic has or is expected to have on the business, and concluded that it was not a triggering event for impairment purposes and there was no indication of impairment of long-lived assets, except as indicated above, for the nine months ended September 30, 2020.

The Company capitalizes interest costs relating to construction financing during the period of construction, which is included in energy assets, net in the Company’s condensed consolidated balance sheets. Capitalized interest is amortized to cost of revenues in the Company’s condensed consolidated statements of income on a straight line basis over the useful life of the associated energy asset.

						2020						2019						2020						2019
Capitalized interest						$	1,096					$	632					$	2,870					$	2,210

As of September 30, 2020 and December 31, 2019, there are three ESPC asset projects which are included within energy assets, net on the Company’s condensed consolidated balance sheets. The Company controls and operates the assets as well as obtains financing during the construction period of the assets. As the Company has an obligation to the customer for performance of the

asset, the Company records a liability associated with these energy assets, although, the customer is responsible for payments to the lender based on the energy asset’s production. As of September 30, 2020 and December 31, 2019, the liabilities recognized in association with these assets were $11,077 and $10,243, respectively, of which $225 and $827, respectively, have been classified as the current portion and are included in accrued expenses and other current liabilities. The remainder is included in other liabilities in the accompanying condensed consolidated balance sheets.

During the three months ended June 30, 2020, the Company acquired one energy project, which did not constitute a business in accordance with ASC 805-50, Business Combinations. The Company acquired the energy project in exchange for a total purchase price of $1,251, which included cash of $1,031 paid by the Company, issuance of a promissory note payable to the sellers of $204, detailed further in Note 16, and $16 of rollover equity in connection with shares of one of the Company’s subsidiaries issued to the sellers. As of September 30, 2020, the Company has remaining deferred purchase price consideration on previously closed projects of $1,446 that will be paid upon final completion of the respective projects and throughout 2020. The Company has a definitive agreement from prior periods, which has recently been amended, to purchase eight additional solar projects from developers for a total purchase price of $10,242, of which the Company has not made any payments to the developers for those projects.

As of September 30, 2020, the Company had $1,484 in asset retirement obligations (“AROs”) assets recorded in project assets, net of accumulated depreciation, and $1,622 in ARO liabilities recorded in accrued expenses and other current liabilities and other liabilities. During the three and nine months ended September 30, 2020, the Company recorded $20 and $58, respectively, of depreciation expense related to the ARO assets. During the three and nine months ended September 30, 2020, the Company recorded $21 and $64, respectively, in accretion expense to the ARO liabilities, which is reflected in the accretion of ARO and contingent consideration on the condensed consolidated statements of cash flows. The Company’s current ARO liabilities relate to the removal of equipment and pipelines at certain renewable gas projects and obligations related to the decommissioning of certain solar facilities and wind turbines.

7. INCOME TAXES

The Company recorded a provision for income taxes of $3,100 and $939 for the three months ended September 30, 2020 and 2019, respectively. The Company recorded a provision for income taxes of $597 and $2,000 for the nine months ended September 30, 2020 and 2019, respectively. The estimated effective annualized tax rate impacted by the period discrete items is 14.9% for the three months ended September 30, 2020, compared to a 10.1% of estimated effective annualized tax rate for the three months ended September 30, 2019. The estimated effective annualized tax rate impacted by the period discrete items is 1.8% for the nine months ended September 30, 2020, compared to a 9.2% of estimated effective annualized tax rate for the nine months ended September 30, 2019.

The principal reasons for the difference between the statutory rate and the estimated annual effective rate for 2020 were the effects of investment tax credits to which the Company is entitled from solar plants which have been placed into service or are forecasted to be placed into service during 2020, the tax deductions related to the Section 179D deduction, the tax rate benefits associated with net operating loss carryback made possible by the passing of the CARES Act on March 27, 2020 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 2019 were the effects of investment tax credits to which the Company is entitled from solar plants which have been placed into service or were forecasted to be placed into service during 2019.

The investment tax credits and production tax credits to which the Company may be entitled fluctuate from year to year based on the cost of the renewable energy plants the Company places or expects to place in service and production levels at company owned facilities in that year. As part of the Tax Extender and Disaster Relief Act of 2019, signed into law December 20, 2019, Section 179D was extended through December 31, 2020.

At September 30, 2020 and December 31, 2019, the Company had approximately $80 of total gross unrecognized tax benefits (both net of the federal benefit on state amounts) representing the amount of unrecognized tax benefits that, if recognized, would favorably affect the effective income tax rate in any future periods.

The Company has presented all deferred tax assets and liabilities as noncurrent, net liabilities on its condensed consolidated balance sheets as of September 30, 2020, and December 31, 2019.

8. LEASES

The Company enters into a variety of operating lease agreements through the normal course of its business including certain administrative offices. The leases are long-term, non-concealable real estate lease agreements, expiring at various dates through fiscal 2028. The agreements generally provide for fixed minimum rental payments and the payment of utilities, real estate taxes, insurance and repairs. The Company also leases certain land parcels related to our energy projects, expiring at various dates through fiscal 2050. The office and land leases make up a significant portion of the Company’s operating lease activity. Many of these leases have one or more renewal options that allow the Company, at its discretion, to renew the lease for six months to seven years. Only renewal options that the Company believed were likely to be exercised were included in our lease calculations. Many land leases include minimum lease payments that increase when the related project becomes operational. In these cases, the commercial operation date was estimated by the Company and used to calculate the estimated minimum lease payments.

Supplemental balance sheet information related to leases at September 30, 2020 and December 31, 2019 is as follows:

The Company has determined that certain power purchase agreements (“PPAs”) contain a lease component in accordance with ASC 840, Leases. The Company recognized $2,261 and $6,546 of operating lease revenue under these agreements during the three and nine months ended September 30, 2020, respectively, which was reflected in revenues on the condensed consolidated statements of income. The Company recognized $2,243 and $6,737 of operating lease revenue under these agreements during the three and nine months ended September 30, 2019, respectively, which was reflected in revenues on the condensed consolidated statements of income.

Sale-Leaseback

Most of the solar photovoltaic (“solar PV”) projects sold to date under the sale-leaseback program have been determined by the Company to be financing leases. The Company defers any gain or loss, representing the excess or shortfall of cash received from the investor compared to the net book value of the asset in the Company’s condensed consolidated balance sheets at the time of the sale. The Company records the long term portion of any deferred gain or loss in its condensed consolidated balance sheets in other liabilities and other assets, respectively, and the current portion in accrued expenses and other current liabilities and prepaid expenses and other current assets. The deferred amounts are amortized over the lease term and are included in cost of revenues in its condensed consolidated statements of income. Net gains from amortization expense in cost of revenues related to deferred gains and losses was $57 and $57 for the three months ended September 30, 2020 and 2019, respectively. Net gains from amortization expense in cost of revenues related to deferred gains and losses was $170 and $172 for the nine months ended September 30, 2020 and 2019, respectively.

During the third quarter of 2018, the Company entered into an agreement with an investor which gives us the option to sell and contemporaneously lease back solar PV projects through August 2019 up to a maximum funding amount of $100 million. In January 2020, the Company amended the August 2018 agreement with the investor to extend the end date of the agreement to November 24, 2020 and increase the maximum funding amount up to $150 million. During the nine months ended September 30,

9. COMMITMENTS AND CONTINGENCIES

The Company from time to time issues letters of credit and performance bonds, with their third-party lenders, to provide collateral.

Legal Proceedings

The Company is involved in a variety of claims and other legal proceedings generally incidental to its normal business activities. While the outcome of any of these proceedings cannot be accurately predicted, the Company does not believe the ultimate resolution of any of these existing matters would have a material adverse effect on its financial condition or results of operations.

Commitments as a Result of Acquisitions

In August 2018, the Company completed an acquisition which provided for a revenue earn-out contingent upon the acquired business meeting certain cumulative revenue targets over five years from the acquisition date. The Company evaluated financial forecasts of the acquired business and concluded that the fair value of this earn-out was approximately $555, which was subsequently increased to $678 as of December 31, 2019 which remained consistent at September 30, 2020, and is recorded in other liabilities on the condensed consolidated balance sheets. The contingent consideration will be paid annually, beginning in May 2020, if any of the cumulative revenue targets are achieved. No payments have been made to date. The fair value of the earn-out will be re-evaluated at each reporting period and adjustments will be recorded as needed. See Note 10 for additional information.

In November 2018, the Company completed an acquisition of certain lease options, which provided for an earn-out if the lease option is exercised and if certain financial metrics are achieved. The Company evaluated the acquired lease options and concluded that the fair-value of this contingent liability was approximately $363, which was subsequently increased to $378 at December 31, 2019 which remained consistent at September 30, 2020, and is recorded in accrued expenses and other current liabilities and other liabilities on the condensed consolidated balance sheets. Payments will be made when milestones are achieved. The contingent liability will be re-evaluated at each reporting period and adjustments will be recorded as needed.

In April 2020, the Company completed an acquisition which provided for a profit earn-out contingent upon the acquired project meeting certain financial return targets. The Company evaluated the financial forecasts of the acquired asset and concluded that fair value of the earn-out was $0 at completion of the acquisition which will be re-evaluated at each reporting period. The contingent consideration will be paid annually beginning in 2021, if the financial return targets are achieved.

10. FAIR VALUE MEASUREMENT

The Company recognizes certain 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 upon unadjusted quoted prices for identical instruments traded in active markets.

Level 2: Inputs are based upon 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 the Company’s financial instruments measured at fair value on a recurring basis:

									Fair Value as of
			Level						September 30, 2020						December 31, 2019
Assets:
Interest rate swap instruments			2						$	—					$	15
Commodity swap instruments			2						—						198
Total assets									$	—					$	213
Liabilities:
Interest rate swap instruments			2						$	11,128					$	6,236
Commodity swap instruments			2						44						—
Make-whole provisions			2						1,352						918
Contingent consideration			3						678						678
Total liabilities									$	13,202					$	7,832

The fair value of the Company’s interest rate swaps was determined using cash flow analysis on the expected cash flow of the contract in combination with observable market-based inputs, including interest rate curves and implied volatility. As part of this valuation, the Company considered the credit ratings of the counterparties to the interest rate swaps to determine if a credit risk adjustment was required.

The fair value of the Company’s commodity swaps was determined using a cash flow analysis on the expected cash flow of the contract in combination with observable forward price inputs obtained from a third-party pricing source. As part of this valuation, the Company considered the credit ratings of the counterparties to the commodity swaps to determine if a credit risk adjustment was required.

The fair value of the Company’s make-whole provisions was determined by either comparing it against the rates of similar debt instruments under similar terms without a make-whole provision obtained from various highly rated third-party pricing sources or evaluating the present value of the prepayment fee.

The fair value of the Company’s contingent consideration liabilities were determined by evaluating the acquired asset’s future financial forecasts and evaluating which, if any, of the cumulative revenue targets, financial metrics and/or milestones are likely to be met. The Company has classified contingent consideration related to certain acquisitions within level 3 of the fair value hierarchy because the fair value is derived using significant unobservable inputs, which include discount rates and probability-weighted cash flows. The Company determined the fair value of its contingent consideration obligations based on a probability-weighted income approach derived from financial performance estimates and probability assessments of the attainment of certain

(In thousands) (Unaudited) (Continued)

targets. The Company establishes discount rates to be utilized in its valuation models based on the cost to borrow that would be required by a market participant for similar instruments.

The key assumptions as of September 30, 2020 related to the contingent consideration from the acquisition of certain assets of Chelsea Group Limited, used in the model include a discount rate of 18% for purposes of discounting the low and base case scenarios associated with achievement of the financial based earn-out. The probabilities assigned to these scenarios were 50% for both the low and base case scenarios. An increase or decrease in the probability of achievement of any scenario could result in a significant increase or decrease to the estimated fair value of the contingent consideration liability.

The following table sets forth a summary of changes in fair value of contingent liability classified as level 3 for the nine months ended September 30, 2020 and September 30, 2019:

			Nine Months Ended September 30, 2020						Nine Months Ended September 30, 2019
Contingent consideration liability balance at December 31, 2019 and 2018			$	678					$	600
Changes in the fair value of contingent consideration obligation			—						50
Contingent consideration liability balance at September 30, 2020 and 2019			$	678					$	650

The fair value of financial instruments is determined by reference to observable market data and other valuation techniques, as appropriate. The only category of financial instruments where the difference between fair value and recorded book value is notable is long-term debt. At September 30, 2020 and December 31, 2019 the fair value of the Company’s long-term debt was estimated using discounted cash flows analysis, based on the Company’s current incremental borrowing rates for similar types of borrowing arrangements which are considered to be level 2 inputs. There have been no transfers in or out of level 2 or level 3 financial instruments for the nine months ended September 30, 2020 and the year ended December 31, 2019.

Based on the analysis performed, the fair value and the carrying value of the Company’s long-term debt, excluding financing leases, are as follows:

			As of September 30, 2020												As of December 31, 2019
			Fair Value						Carrying Value						Fair Value						Carrying Value
Long-term debt (Level 2)			$	318,816					$	313,550					$	309,377					$	307,508

The Company is also required periodically to measure certain other assets at fair value on a nonrecurring basis, including long-lived assets, goodwill and other intangible assets. There were no assets recorded at fair value on a non-recurring basis at September 30, 2020 or December 31, 2019.

12. INVESTMENT FUNDS AND OTHER VARIABLE INTEREST ENTITIES

Investment Funds

In each of September 2015, June 2017, June 2018, October 2018, and December 2019, the Company formed an investment fund with a different third-party investor which granted the applicable investor ownership interests in the net assets of certain of the Company’s renewable energy project subsidiaries. The Company currently has five such investment funds each with a different third-party investor.

The Company consolidates the investment funds, and all inter-company balances and transactions between the Company and the investment funds are eliminated in its condensed consolidated financial statements. The Company determined that the investment funds meet the definition of a variable interest entity (“VIE”). The Company uses a qualitative approach in assessing the consolidation requirements for VIEs that focuses on determining whether the Company has the power to direct the activities of the VIE that most significantly affect the VIE’s economic performance and whether the Company has the obligation to absorb losses or the right to receive benefits that could potentially be significant to the VIE.

The Company has considered the provisions within the contractual arrangements that grant it power to manage and make decisions that affect the operation of these VIEs, including determining the solar energy systems and associated long-term customer contracts to be sold or contributed to the VIEs, and installation, operation and maintenance of the solar energy systems. The Company considers that the rights granted to the other investors under the contractual arrangements are more protective in

26

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(In thousands) (Unaudited) (Continued)

nature rather than participating rights. As such, the Company has determined it is the primary beneficiary of the VIEs for all periods presented. The Company evaluates its relationships with VIEs on an ongoing basis to ensure that it continues to be the primary beneficiary.

Under the related agreements, cash distributions of income and other receipts by the funds, net of agreed-upon expenses and estimated expenses, tax benefits and detriments of income and loss, and tax benefits of tax credits, are assigned to the funds’ investor and Company’s subsidiaries as specified in contractual arrangements. Certain of these arrangements have call and put options to acquire the investor’s equity interest as specified in the contractual agreements. See Note 13 for additional information on the call and put options.

A summary of amounts related to the investment funds in the Company’s condensed consolidated balance sheets is as follows:

			September 30,						December 31,
			2020(1)						2019(1)
Cash and cash equivalents			$	9,179					$	4,666

(1) The amounts in the above table are reflected in Note 1 on the Company’s condensed consolidated balance sheets. See the Company’s condensed consolidated balance sheets for additional information.

Other Variable Interest Entities

The Company follows guidance on the consolidation of VIEs that requires companies to utilize a qualitative approach to determine whether it is the primary beneficiary of a VIE. The process for identifying the primary beneficiary of a VIE requires consideration of the factors that indicate a party has the power to direct the activities that most significantly impact the joint ventures economic performance, including powers granted to the joint ventures program manager, powers contained in the joint venture governing board and, to a certain extent, a company's economic interest in the joint venture. The Company analyzes its joint ventures and classifies them as either:

•a VIE that must be consolidated because the Company is the primary beneficiary or the joint venture is not a VIE and the Company holds the majority voting interest with no significant participative rights available to the other partners; or

27

Table of Contents

AMERESCO, INC.

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(In thousands) (Unaudited) (Continued)

•a VIE that does not require consolidation and is treated as an equity method investment because the Company is not the primary beneficiary or the joint venture is not a VIE and the Company does not hold the majority voting interest.

Many of the joint ventures are deemed to be VIEs because they lack sufficient equity to finance the activities of the joint venture.

Unconsolidated joint ventures are accounted for under the equity method. For those joint ventures, the Company's investment balances for the joint venture are included in other assets on the condensed consolidated balance sheets and the Company’s pro rata share of net income or loss is included in operating income. The Company’s investments in equity method joint ventures on the condensed consolidated balance sheets as of September 30, 2020 and December 31, 2019 were a net asset of $1,370 and $1,292, respectively. During the three and nine months ended September 30, 2020, the Company recognized expense of $50 and $127, respectively, from equity method joint ventures. During the three and nine months ended September 30, 2019, the Company recognized expense of $73 and $147, respectively from equity method joint ventures.

13. REDEEMABLE NON-CONTROLLING INTERESTS

The Company’s wholly owned subsidiary with a membership interest in the investment fund formed in the third quarter of 2015 has the right, beginning on the fifth anniversary of the final funding of the variable rate construction and term loans due 2023 and extending for six months, to elect to require the non-controlling interest holder to sell all of its membership units to the Company’s wholly owned subsidiary, a call option. The Company’s investment fund, which was formed in the third quarter of 2015, also includes a right, beginning on the sixth anniversary of the final funding and extending for one year, for the non-controlling interest holder to elect to require the Company’s wholly owned subsidiary to purchase all of its membership interests in the fund, a put option.

The Company’s wholly owned subsidiary with a membership interest in the investment fund formed in the second quarter of 2017 has the right, beginning on the fifth anniversary of the final funding of the non-controlling interest holder and extending for six months, to elect to require the non-controlling interest holder to sell all of its membership units to the Company’s wholly owned subsidiary, a call option. The Company’s investment fund formed in the second quarter of 2017 also includes a right, beginning on the sixth anniversary of the final funding and extending for one year, for the non-controlling interest holder to elect to require the Company’s wholly owned subsidiary to purchase all of its membership interests in the fund, a put option.

The Company’s wholly owned subsidiary with a membership interest in the investment fund formed in the second quarter of 2018 has the right, beginning on the fifth anniversary of the investment fund’s final project being placed into service and extending for six months, to elect to require the non-controlling interest holder to sell all of its membership units to the Company’s wholly owned subsidiary, a call option. The Company’s investment fund formed in the second quarter of 2018 also includes a right, upon the expiration of the call option and extending for six months, for the non-controlling interest holder to elect to require the Company’s wholly owned subsidiary to purchase all of its membership interests in the fund, a put option.

The Company’s wholly owned subsidiary with a membership interest in the investment fund formed in the fourth quarter of 2018 has the right, beginning on the fifth anniversary on the last projects placed in-service date and extending for six months, to elect to require the non-controlling interest holder to sell all of its membership units to the Company’s wholly owned subsidiary, a call option. The Company’s investment fund formed in the fourth quarter of 2018 also includes a right, upon the expiration of the call option and extending for six months, for the non-controlling interest partner to elect to require the Company’s wholly owned subsidiary to purchase all of its membership interests in the fund, a put option.

The Company’s wholly owned subsidiary with a membership interest in the investment fund formed in the fourth quarter of 2019 has the right, beginning on the fifth anniversary on the last projects placed in-service date and extending for six months, to elect to require the non-controlling interest holder to sell all of its membership units to the Company’s wholly owned subsidiary, a call option. The Company’s investment fund formed in the fourth quarter of 2019 also includes a right, beginning six months after the fifth anniversary of the final funding and extending for one year, for the non-controlling interest partner to elect to require the Company’s wholly owned subsidiary to purchase all of its membership interests in the fund, a put option.

The purchase price for two of the investment funds investors’ interests under the call options is equal to the fair market value of such interest at the time the option is exercised. The purchase price for two of the investment funds investor’s interests under the call options is equal to the greater of (i) the fair market value of such interests at the time the option is exercised or (ii) 7% of the investors’ contributed capital balance at the time the option is exercisable. The purchase price for the remaining investment fund investor’s interests under the call options is equal to the greater of (i) the fair market value of such interests at the time the option is exercised or (ii) 5% of the investors’ contributed capital balance at the time the option is exercisable. The call options are

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(In thousands) (Unaudited) (Continued)

exercisable beginning on the date that specified conditions are met for each respective fund. None of the call options are expected to become exercisable prior to 2021.

The purchase price for two of the funds investors’ interests in the investment funds under the put options is the lessor of fair market value at the time the option is exercised and a specified amount, ranging from $659 - $917. The purchase price for the two of the remaining funds investors’ interest in the investment funds under the put options is the sum of (i) the fair market value at the time the option is exercised, and (ii) the closing costs incurred by the investor in connection with the exercise of the put option. The purchase price for the remaining fund investors’ interest in the investment funds under the put options is the lessor of fair market value at the time the option is exercised and the sum of (i) 5% of the investors’ contributed capital balance at the time the option is exercisable, and (ii) the fair market value of any unpaid tax law change losses incurred by the investor in connection with the exercise of the put option. The put options for the investment funds are exercisable beginning on the date that specified conditions are met for each respective fund. The put options are not expected to become exercisable prior to 2022.

Because the put options represents redemption features that are not solely within the control of the Company, the non-controlling interests in these funds are presented outside of permanent equity. Redeemable non-controlling interests are reported using the greater of their carrying value at each reporting date (which is impacted by attribution under the hypothetical liquidation at book value method) or their estimated redemption value in each reporting period. At both September 30, 2020 and December 31, 2019 redeemable non-controlling interests were reported at their carrying value totaling $36,421 and $31,616, respectively, as the carrying value at each reporting period was greater than the estimated redemption value.

No awards to individuals who were not either an employee or director of the Company were granted during the nine months ended September 30, 2020 or during the year ended December 31, 2019.

Stock Option Grants

The Company’s 2020 Stock Incentive Plan (the “2020 Plan”), was adopted by the Company’s Board of Directors in February 2020 and approved by its stockholders in May 2020. The 2020 Plan provides for the grant of incentive stock options, non-statutory stock options, stock appreciation rights, restricted stock awards and other stock-based awards. Upon its effectiveness, 5,000 shares of the Company’s Class A common stock were reserved for issuance under the 2020 Plan.

During the three months ended September 30, 2020, the Company granted 95 common stock options to certain employee and directors under its 2020 Stock Incentive Plan, which have a contractual life of ten years and vest over a five-year period. During the nine months ended September 30, 2020, the Company granted 376 common stock options to certain employees and directors under its 2010 and 2020 Stock Incentive Plans, which have a contractual life of ten years and vest over a five-year period.

Employee Stock Purchase Plan

In May 2020, the Company amended its 2017 Employee Stock Purchase Plan ("ESPP") which permits eligible employees to purchase up to an aggregate of 350 shares of the Company’s Class A common stock. This plan commenced December 1, 2017 and was previously amended on August 2018. The ESPP allows participants to purchase shares of common stock at a 5% discount from the fair market value of the stock as determined on specific dates at six-month intervals. During the nine months ended September 30, 2020 and 2019, the Company issued 28 and 22 shares, respectively, under the ESPP.

Share Repurchase Program

In April 2016, the Company’s Board of Directors authorized the repurchase of up to $10,000 of the Company’s Class A common stock from time to time on the open market in privately negotiated transactions. The Company’s Board of Directors authorized an increase in the Company’s share repurchase authorization to $15,000 of the Company's Class A common stock in February 2017 and to $17,553 of the Company's Class A common stock in August 2019, in each case, from time to time on the open market or in privately negotiated transactions. The timing and amount of any shares repurchased will be determined by the Company's management based on its evaluation of market conditions and other factors. Any repurchased shares will be available for use in connection with its stock plans and for other corporate purposes. The repurchase program has and will be funded using the Company's working capital and borrowings under its revolving line of credit. The Company accounts for share repurchases using the cost method. Under this method, the cost of the share repurchase is recorded entirely in treasury stock, a contra equity account. During the nine months ended September 30, 2020, the Company repurchased an immaterial amount of shares of common stock. During the three and nine months ended September 30, 2019, the Company repurchased 10 shares of common stock.

(3) These agreements are sale-leaseback arrangements that provide for the sale of solar PV projects to a third party investor and the simultaneous leaseback of the projects. In accordance with Topic 842, Leases, these transactions are accounted for as failed sales as the Company retains control of the underlying assets and as such, are classified as financing liabilities. The low interest rates are the results of tax credits which were transferred to the counterparty.

Senior Secured Credit Facility - Revolver and Term Loan

In March 2020, the Company amended the Company’s senior secured credit facility which increased the total funded debt to EBITDA covenant ratio to a maximum of 3.75 for the year ended December 31, 2020.

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, 2019 included in our Annual Report on Form 10-K for the year ended December 31, 2019 filed on March 4, 2020 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 Annual Report on Form 10-K for the year ended December 31, 2019, Item 1A of our Quarterly Report on Form 10-Q for the quarter ended March 31, 2020 and elsewhere in this Quarterly Report on Form 10-Q. 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 provider of energy efficiency solutions for facilities throughout North America and Europe. We provide solutions that enable customers to reduce their energy consumption, lower their operating and maintenance costs and realize environmental benefits. Our comprehensive set of services includes upgrades to a facility’s energy infrastructure and the construction and operation of small-scale renewable energy plants.

In addition to organic growth, strategic acquisitions of complementary businesses and assets have been an important part of our historical development. Since inception, we have completed numerous acquisitions, which have enabled us to broaden our service offerings and expand our geographical reach.

Key Factors and Trends

COVID-19 Update

In March 2020, the World Health Organization categorized Coronavirus Disease 2019 as a pandemic, and the President of the United States declared the COVID-19 outbreak a national emergency. We are closely monitoring the impact of the COVID-19 pandemic on all aspects of our business, including how it may impact our suppliers, customers, employees and supply chains. While we did not incur significant disruptions during the nine months ended September 30, 2020 from the COVID-19 pandemic, we are unable to predict the impact that the COVID-19 pandemic will have on our financial condition, results of operations and cash flows due to numerous uncertainties. These uncertainties include 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.

Further, the overall impact of COVID-19 on our condensed consolidated results of operations for the nine months ended September 30, 2020 was not material. However, the impact that COVID-19 will have on our consolidated results of operations throughout 2020 remains uncertain. We expect to experience delays in our project award conversions and potential construction slowdowns as a result of known shelter-in-place restrictions. 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.

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 Annual Report on Form 10-K for the year ended December 31, 2019 (“Annual Report”), and the risks described in Item 1A. Risk Factors in this Quarterly Report on Form 10-Q.

Backlog and Awarded Projects

Total construction backlog represents projects that are active within our ESPC 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 54 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 sub-contractor, 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, however, depending upon 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. Fully-contracted backlog begins converting into revenues generated from backlog over time using cost based input methods once construction has commenced. 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 Annual Report, and the risks described in Item 1A. Risk Factors in this Quarterly Report on Form 10-Q.

The overall impact of COVID-19 on our condensed consolidated results of operations for the nine months ended September 30, 2020 was not material. However, the impact that COVID-19 will have on our consolidated results of operations throughout 2020 remains uncertain. We expect to experience delays in our project award conversions and potential construction slowdowns as a result of known shelter-in-place restrictions. 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. 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 Annual Report, and the risks described in Item 1A. Risk Factors in the Quarterly Report on Form 10-Q for the quarter ended March 31, 2020.

As of September 30, 2020, we had fully-contracted backlog of approximately $1,033.7 million in expected future revenues under signed customer contracts for the installation or construction of projects; and we also had been awarded projects for which we had not yet signed customer contracts with estimated total future revenues of an additional $1,211.3 million. As of September 30,

2019, we had fully-contracted backlog of approximately $787.2 million in expected future revenues under signed customer contracts for the installation or construction of projects; and we also had been awarded projects for which we had not yet signed customer contracts with estimated total future revenues of an additional $1,434.9 million.

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. As of September 30, 2020 and 2019, our 12-month project backlog was $605.9 million and $437.7 million, respectively.

As of September 30, 2020, we had O&M backlog of approximately $1,120.8 million in expected future revenues under signed multi-year customer contracts for the delivery of O&M services. As of September 30, 2019, we had O&M backlog of approximately $908.9 million in expected future revenues under signed multi-year customer contracts for the delivery of O&M services. As of September 30, 2020 and 2019, our 12-month O&M backlog was $60.0 million and $60.6 million, respectively.

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 $784.6 million and $572.0 million as of September 30, 2020 and 2019, respectively.

Critical Accounting Policies and Estimates

This discussion and analysis of our financial condition and results of operations is based upon our condensed consolidated financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States. The preparation of these condensed consolidated financial statements requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenue, expense and related disclosures. The most significant estimates with regard to these condensed consolidated financial statements relate to our estimates of final construction contract profit in accordance with accounting for long-term contracts under the revenue recognition requirements of contracts with our customers, allowance for credit losses, inventory reserves, realization of project development costs, leases, fair value of derivative financial instruments, accounting for business acquisitions, stock-based awards, impairment of long-lived assets and goodwill, income taxes, self-insurance reserves and potential liability in conjunction with certain commitments and contingencies. Actual results could differ from those estimates.

Such estimates and assumptions are based on historical experience and on various other factors that management believes to be reasonable under the circumstances. Estimates and assumptions are made on an ongoing basis, and accordingly, the actual results may differ from these estimates under different assumptions or conditions.

The following are certain critical accounting policies that, among others, affect our more significant judgments and estimates used in the preparation of our condensed consolidated financial statements:

•Revenue Recognition;

•Energy Assets;

•Leases;

•Goodwill and Intangible Assets;

•Derivative Financial Instruments; and

•Variable Interest Entities.

Further details regarding our critical accounting policies and estimates can be found in Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations of our Annual Report. In addition, please refer to Note 2, Summary of Significant Accounting Policies, of our Notes to the audited consolidated financial statements for the year ended December 31, 2019, and notes thereto, included in the Company’s Annual Report. The Company has determined that no material changes concerning our critical accounting policies have occurred since December 31, 2019.

Year-Over-Year Period Comparison

Revenues

The following tables set forth a comparison of our revenues for the periods presented (in thousands):

			Three Months Ended September 30,
			2020						2019						$ Change						% Change
Revenues			$	282,507					$	212,026					$	70,481					33.2		%

			2020						2019						$ Change						% Change
Revenues			$	717,956					$	560,321					$	157,635					28.1		%

Revenues increased for the three months ended September 30, 2020 compared to the same period of 2019 primarily due to a $69.5 million increase in our project revenue, a $4.5 million increase in our energy assets revenue, and a $0.1 million increase in our O&M revenue, partially offset by a $1.9 million decrease in our integrated-PV revenue and a $1.8 million decrease in other revenue.

Revenues increased $157.6 million, or 28.1% to $718.0 million for the nine months ended September 30, 2020 compared to the same period of 2019 primarily due to a $153.3 million increase in our project revenue, a $10.5 million increase in our energy asset revenue, and a $4.5 million increase in our O&M revenue, partially offset by a $6.3 million decrease in our integrated-PV revenue and a $4.3 million decrease in other revenue.

Cost of Revenues and Gross Profit

The following tables set forth a comparison of our cost of revenues and gross profit for the periods presented (in thousands):

			Three Months Ended September 30,
			2020						2019						$ Change						% Change
Cost of revenues			$	231,133					$	167,333					$	63,800					38.1		%
Gross margin			18.2		%				21.1		%
			Nine Months Ended September 30,
			2020						2019						$ Change						% Change
Cost of revenues			$	588,628					$	439,857					$	148,771					33.8		%
Gross margin			18.0		%				21.5		%

Cost of revenues increased $63.8 million, or 38.1%, to $231.1 million and gross margin percentage decreased to 18.2%, from 21.1% for the three months ended September 30, 2020 compared to the same period of 2019. Cost of revenues increased $148.8 million, or 33.8%, to $588.6 million and gross margin percentage decreased to 18.0%, from 21.5%, for the nine months ended September 30, 2020 compared to the same period of 2019. The increase in cost of revenues for the three and nine months ended September 30, 2020 is primarily due to the increases in project revenues. The decrease in gross margin for both periods is primarily due to a higher proportion of lower margin projects as part of the revenue mix which includes increased levels of design-build work and lower margin energy and incentive revenue compared to the prior year.

Selling, General and Administrative Expenses

The following tables set forth a comparison of our selling, general and administrative expenses for the periods presented (in thousands):

			Three Months Ended September 30,
			2020						2019						$ Change						% Change
Selling, general and administrative expenses			$	26,859					$	31,231					$	(4,372)					(14.0)		%

			2020						2019						$ Change						% Change
Selling, general and administrative expenses			$	82,403					$	87,396					$	(4,993)					(5.7)		%

Selling, general and administrative expenses decreased $4.4 million, or 14.0%, to $26.9 million for the three months ended September 30, 2020, compared to the same period of 2019 due to a decrease in salaries and benefits of $2.1 million primarily resulting from higher utilization, lower professional fees of $ 1.0 million and a decrease in travel expenses of $0.7 million. For the nine months ended September 30, 2020, selling, general and administrative expenses decreased $5.0 million, or 5.7%, to $82.4 million compared to the same period of 2019, primarily due to a decrease in salaries and benefits of $5.3 million resulting from increased utilization, a decrease in travel expense of $1.5 million and a decrease in professional fees of $1.2 million partially offset by a gain of $2.2 million on the deconsolidation of a variable interest entity recognized during the first quarter of 2019.

Amortization expense of intangible assets related to customer relationships, non-compete agreements, technology and trade names is included in selling, general and administrative expenses in the condensed consolidated statements of income. For the three months ended September 30, 2020 and 2019, we recorded amortization expense related to these intangible assets of $0.2 million. For the nine months ended September 30, 2020 and 2019, we recorded amortization expense related to these intangible assets of $0.5 million.

Other Expenses, Net

Other expenses, net, includes gains and losses from derivatives and foreign currency transactions, interest income and expenses, amortization of deferred financing costs, and certain government incentives. Other expenses, net decreased $0.5 million to $3.7 million for the three months ended September 30, 2020 compared to the same period of 2019, primarily due to government incentives of $0.7 million received at the commercial operation date of certain solar assets which were recorded as other income. Other expenses, net increased $1.8 million to $13.2 million for the nine months ended September 30, 2020 compared to the same period of 2019, primarily due to higher interest expenses of $3.0 million partially offset by government incentives of $1.5 million received which were recorded as other income.

Income Before Taxes

Income before taxes increased $11.5 million, or 124.3%, to $20.8 million for the three months ended September 30, 2020 compared to the same period of 2019, due to the reasons described above. Income before taxes increased $12.1 million, or 55.5%, to $33.8 million for the nine months ended September 30, 2020 compared to the same period of 2019, due to the reasons described above.

Provision (Benefit) from Income Taxes

The provision for income taxes was $3.1 million for the three months ended September 30, 2020, compared to $0.9 million for the three months ended September 30, 2019. The estimated effective annualized tax rate impacted by period discrete items applied for the three months ended September 30, 2020 was 14.9% compared to 10.1% for the three months ended September 30, 2019.

The provision for income taxes was $0.6 million for the nine months ended September 30, 2020, compared to $2.0 million for the nine months ended September 30, 2019. The estimated effective annualized tax rate impacted by period discrete items applied for the nine months ended September 30, 2020 was 1.8% compared to 9.2% for the nine months ended September 30, 2019.

The principal reasons for the difference between the statutory rate and the estimated annual effective rate for 2020 were the effects of investment tax credits to which the Company is entitled from solar plants which have been placed into service or are forecasted to be placed into service during 2020, tax deductions related to Section 179D deductions, tax rate benefits associated with net operating loss carrybacks made possible by the passing of the CARES Act on March 27, 2020 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 2019 was the effects of investment tax credits to which the Company is entitled from solar plants which were placed into service or were forecasted to be placed into service during 2019. We estimate the discrete benefit associated with the net operating loss provisions of the CARES Act to be approximately $2.0 million, an estimated refund of taxes paid in prior years of approximately $1.7 million and the carryback provides an additional refund of approximately $3.6 million related to Alternative Minimum Tax.

The investment tax credits and production tax credits to which the Company may be entitled fluctuate from year to year based on the cost of the renewable energy plants the Company places or expects to place in service and production levels at Company owned facilities in the respective year. As part of the Tax Extender and Disaster Relief Act of 2019, signed into law December 20, 2019 Section 179D was extended through December 31, 2020.

Business Segment Analysis

We report results under ASC 280, Segment Reporting. Our reportable segments for the three and nine months ended September 30, 2020 are U.S. Regions, U.S. Federal, Canada and Non-Solar Distributed Generation (“DG”). 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, which include the construction of small-scale plants that we own or develop for customers that produce electricity, gas, heat or cooling from renewable sources of energy; and O&M services. For our energy efficiency projects, we typically enter into energy savings performance contracts (“ESPCs”), under which we agree to develop, design, engineer and construct a project and also commit that the project will satisfy agreed upon performance standards that vary from project to project. When we are not providing a commitment to the customer for long-term performance standards, we may refer to the project as “Design-Build.” 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 offers enterprise energy management services, consulting services and integrated-PV. These segments do not include results of other activities, such as corporate operating expenses not specifically allocated to the segments.

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.

Liquidity and Capital Resources

Sources of Liquidity

Since inception, we have funded operations primarily through cash flow from operations, advances from Federal ESPC projects and various forms of debt. We believe that the cash and cash equivalents and availability under our revolving senior secured credit facility, combined with our access to credit markets, will be sufficient to fund our operations through the next twelve months and thereafter. See Note 2 of the audited consolidated financial statements for the year ended December 31, 2019, and notes thereto, included in the Company’s Annual Report.

We believe we have sufficient liquidity to satisfy our cash needs, 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 includes limiting discretionary spending across the organization and re-prioritizing our capital projects amid the COVID-19 pandemic.

On March 27, 2020, the U.S. government enacted the Coronavirus Aid, Relief, and Economic Security Act (“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. We estimate the payment of approximately $5 million of employer payroll taxes otherwise due in 2020 will be 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). We estimate the discrete benefit associated with the net operating loss provisions of the CARES Act to be approximately $2,000, an estimated refund of taxes paid in prior years of approximately $1,700 and the carryback provides an additional refund of approximately $3,600 related to Alternative Minimum Tax credits.

Proceeds from our Federal ESPC projects are generally received through agreements to sell the ESPC receivables related to certain ESPC contracts to third-party investors. We use the advances from the investors under these agreements to finance the projects. Until recourse to us ceases for the ESPC receivables transferred to the investor, upon final acceptance of the work by the government customer, we are the primary obligor for financing received. The transfers of receivables under these agreements do not qualify for sales accounting until final customer acceptance of the work, so the advances from the investors are not classified as operating cash flows. Cash draws that we receive under these ESPC agreements are recorded as financing cash inflows. The use of the cash received under these arrangements to pay project costs is classified as operating cash flows. Due to the manner in which the ESPC contracts with the third-party investors are structured, our reported operating cash flows are materially impacted by the fact that operating cash flows only reflect the ESPC contract expenditure outflows and do not reflect any inflows from the corresponding contract revenues. Upon acceptance of the project by the federal customer the ESPC receivable and corresponding ESPC liability are removed from our condensed consolidated balance sheet as a non-cash settlement.

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.

The amount of interest capitalized relating to construction financing during the period of construction for the nine months ended September 30, 2020 and 2019 was $2.9 million and $2.2 million, respectively.

Cash Flows

The following table summarizes our cash flows from operating, investing and financing activities:

			Nine Months Ended September 30,
			2020						2019						$ Change
Cash flows from operating activities			$	(83,789)					$	(120,725)					$	36,936

Total net cash flows			$	(6,357)					$	(27,529)					$	21,172

Cash Flows from Operating Activities

Operating activities used $83.8 million of net cash during the nine months ended September 30, 2020 primarily due to an increase of $160.2 million in Federal ESPC receivables, which as described above, 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. This was partially offset by net income of $33.2 million, and non-cash compensation, depreciation, amortization, accretion, contingent consideration, deferred income taxes, net loss on derivatives, unrealized foreign exchange loss and other non-cash items totaling $41.9 million which provided cash for operations. Increases in accounts receivable including retainage, project development costs, and decreases in accounts payable, accrued expenses and other current liabilities and income taxes payable used $39.6 million in cash. These were offset by decreases in inventory, costs and estimated earnings in excess of billings, prepaid expenses and other current assets and other assets, and increases in billings in excess of cost and estimated earnings and other liabilities which provided for $40.9 million in cash.

Operating activities used $120.7 million of net cash during the nine months ended September 30, 2019 primarily due to an increase in Federal ESPC receivables of $110.4 million. This was partially offset by net income of $19.7 million and non-cash compensation, depreciation, amortization, accretion, contingent consideration, deferred income taxes, gain on deconsolidation of a VIE, net gain on derivatives, unrealized foreign exchange loss and other non-cash items totaling $29.1 million which provided cash for operations. Increases in accounts receivable including retainage, inventory, costs and estimated earnings in excess of billings, prepaid expenses and other current assets, project development costs and other assets, and decreases in accounts payable, accrued expenses and other current liabilities, billings in excess of costs and estimated earnings and other liabilities used $61.7 million in cash. These were partially offset by an increase in income tax payable which provided for $2.6 million in cash.

Cash Flows from Investing Activities

Cash flows from investing activities during the nine months ended September 30, 2020 used $127.6 million as we invested $125.5 million in purchases of energy assets and $2.0 million in purchases of other property and equipment. We currently plan to invest approximately $50.0 million to $70.0 million in additional capital expenditures for the remainder of 2020, principally for the construction or acquisition of new renewable energy plants.

Cash flows from investing activities during the nine months ended September 30, 2019 used $79.9 million as we invested $72.1 million on purchases of energy assets and $6.2 million in purchases of other property and equipment and $1.3 million related to acquisitions of businesses.

Cash Flows from Financing Activities

Cash flows from financing activities during the nine months ended September 30, 2020 provided $205.5 million, which was primarily due to proceeds received from Federal ESPC projects and energy assets of $196.0 million and net proceeds from long-term debt financings of $40.6 million. These were primarily offset by payments on long-term debt of $42.6 million.

Cash flows from financing activities during the nine months ended September 30, 2019 provided $172.9 million, which was primarily due to proceeds received from Federal ESPC projects and energy assets of $117.2 million, net proceeds from our senior secured credit facility of $41.3 million, net contributions from redeemable non-controlling interests of $20.2 million and proceeds from long-term debt of $7.6 million. These were partially offset by payments on long-term debt of $18.0 million.

We currently plan additional project financings of approximately $50.0 million to $70.0 million for the remainder of 2020 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.

On March 31, 2020, the Company executed an amendment to its fourth amended and restated bank credit facility. The amendment increased the total funded debt to EBITDA covenant ratio from a maximum of 3.25 to 3.75 for the fiscal quarters ending March 31, 2020 through December 31, 2020. The amendment also increased the Eurocurrency Rate floor to 1% from 0% previously. The total commitment under the amended credit facility (revolving credit, term loan and swing line) remains unchanged, which is $185,000, and the amendment did not result in any restructured payments.

See Note 16, Debt, of Notes to Condensed Consolidated Financial Statements for additional discussion of items impacting the Company’s liquidity.

Off-Balance Sheet Arrangements

We did not have during the periods presented, and we do not currently have, any off-balance sheet arrangements, as defined under SEC rules, such as relationships with unconsolidated entities or financial partnerships, which are often referred to as structured finance or special purpose entities, established for the purpose of facilitating financing transactions that are not required to be reflected on our balance sheet.

Item 3. Quantitative and Qualitative Disclosures About Market Risk

As of September 30, 2020, 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 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.

On October 2, 2020, the staff of the United States Securities and Exchange Commission, or SEC, requested information with respect to revenue recognition for our software-as-a-service, or SaaS, businesses during the period January 1, 2014 through September 30, 2020. We are fully cooperating with the SEC; and the Audit Committee of our Board of Directors is overseeing a review by our outside counsel of our software-as-a-service revenue recognition, including review procedures with respect to the revenue recognized during the period from 2018 to the present. The review to date has not identified material misstatements of our financial results. We intend to continue to cooperate fully with the SEC and promptly to address any material accounting errors or material control weaknesses diagnosed in connection with the inquiry and review.

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

Our business is subject to numerous risks, a number of which are described below and under “Risk Factors” in Part I of our Annual Report on Form 10-K for the year ended December 31, 2019, or Annual Report and Item 1A of our Quarterly Report on Form 10-Q for the quarter ended March 31, 2020, or First Quarter Quarterly Report. We caution you that the following important factor, among others, could cause our actual results to differ materially from those expressed in forward-looking statements made by us or on our behalf in filings with the SEC, press releases, communications with investors and oral statements. Any or all of our forward-looking statements in this Quarterly Report on Form 10-Q and in any other public statements we make may turn out to be wrong. They can be affected by inaccurate assumptions we might make or by known or unknown risks and uncertainties. Many factors mentioned in the discussion below, in our Annual Report and in our First Quarter Quarterly Report will be important in determining future results. Consequently, no forward-looking statement can be guaranteed. Actual future results may differ materially from those anticipated in forward-looking statements. We undertake no obligation to update any forward-looking statements, whether as a result of new information, future events or otherwise, except to the extent required by applicable law. You should, however, consult any further disclosure we make in our reports filed with the SEC.

The Securities and Exchange Commission’s investigation into our revenue recognition and compensation practices in our software-as-a-service, or SaaS, businesses could result in a restatement of our financial statements, investment in remediation of our internal controls, sanctions or penalties, distraction of our management, and litigation from third parties, each of which could adversely affect or cause variability in our financial results.

On October 2, 2020, the staff of the United States Securities and Exchange Commission, or SEC, requested information with respect to revenue recognition for our software-as-a-service, or SaaS, businesses during the period January 1, 2014 through September 30, 2020. We are fully cooperating with the SEC; and the Audit Committee of our Board of Directors is overseeing a review by our outside counsel of our software-as-a-service revenue recognition, including review procedures with respect to the revenue recognized during the period from 2018 to the present. Although, our review to date has not identified material misstatements of our financial results, the SEC’s inquiry is not complete, and there can be no assurance that SEC will not reach a contrary conclusion. In that event, we may be required to restate previously filed financial statements and invest in remediation of our internal controls; the SEC or another regulator make further inquiries or pursue further action that could result in significant costs, expenses, sanctions and penalties; we may be subject to litigation from shareholders; and our management may be distracted by these circumstances.

On October 28, 2020, the Board of Directors of Ameresco, Inc., approved changes to its Share Ownership Guidelines, to make certain clarifying changes and to allow for the Chief Executive Officer to provide waivers of the guidelines, other than to himself. The Stock Ownership Guidelines were originally adopted by the Board of Directors on April 24, 2019, in order to encourage the company’s executive officers and senior management to obtain a significant ownership interest in the company, thereby helping to align their interests with those of Ameresco’s shareholders. The foregoing summary of the amendments to the stock ownership guidelines is qualified in its entirety by reference to the full text of the guidelines, a copy of which is attached as Exhibit 10.1 to this Quarterly Report on Form 10-Q and incorporated herein by reference.
