NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
(In thousands) (Unaudited)


1. BASIS OF PRESENTATION
The accompanying condensed consolidated financial statements of Ameresco, Inc. (including its subsidiaries, the “Company,” “Ameresco,” “we,” “our,” or “us”) are unaudited, according to certain rules and regulations of the Securities and Exchange Commission, and include, in our opinion, normal recurring adjustments necessary for a fair presentation in conformity with accounting principles generally accepted in the United States (“GAAP”) of the results for the periods indicated.
The results of operations for the three and nine months ended September 30, 2021 are not necessarily indicative of results which may be expected for the full year. The December 31, 2020 consolidated balance sheet data was derived from audited financial statements, but certain information and footnote disclosures normally included in consolidated financial statements prepared in accordance with GAAP have been condensed or omitted. The interim condensed consolidated financial statements and accompanying notes should be read in conjunction with the audited consolidated financial statements and accompanying notes for the year ended December 31, 2020, included in our annual report on Form 10-K (“2020 Annual Report” or “2020 Form 10-K”) for the year ended December 31, 2020 filed with the Securities and Exchange Commission on March 2, 2021.
Reclassification
Certain prior period amounts were reclassified to conform to the presentation in the current period.
Significant Risks and Uncertainties
The COVID-19 pandemic has continued to result in global supply chain disruptions and the resurgence of COVID-19 and its variants has caused some governments to extend travel and other restrictions. On September 9, 2021, President Biden issued an Executive Order requiring COVID-19 vaccinations for Federal employees. As a result, we are in the process of implementing this mandate for our employees and subcontractors who work in our Federal business segment.
We have considered the impact of COVID-19 on the assumptions and estimates used, which may change in response to this evolving situation. Results of future operations and liquidity could be adversely impacted by a number of factors associated with the COVID-19 pandemic including payments of outstanding receivable amounts beyond normal payment terms, supply chain disruptions, potential loss of employees due to vaccine mandates, and uncertain demand. As of the date of issuance of these condensed consolidated financial statements, we cannot reasonably estimate the extent to which the COVID-19 pandemic may impact our financial condition, liquidity, or results of operations in the foreseeable future. The ultimate impact of the pandemic on us is highly uncertain and will depend on future developments, and such impacts could exist for an extended period of time, even after the pandemic subsides.
2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
Our accounting policies are set forth in Note 2 to the consolidated financial statements contained in our 2020 Form 10-K. We have included certain updates to those policies below.

Recent Accounting Pronouncements
Income Taxes
In December 2019, the Financial Accounting Standards Board (the “FASB”) issued Accounting Standards Update (“ASU”) 2019-12, Simplifying the Accounting for Income Taxes, which simplifies the accounting for income taxes, eliminates certain exceptions within Accounting Standards Codification (“ASC”) 740, Income Taxes, and clarifies certain aspects of the current

guidance to promote consistency among reporting entities. ASU 2019-12 is effective for our fiscal year beginning after December 15, 2020. We adopted this guidance as of January 1, 2021 and the adoption did not have an impact on our condensed consolidated financial statements.
Reference Rate Reform
In March 2020, the FASB issued ASU 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting. ASU 2020-04, which provides optional guidance for a limited period of time to ease the potential burden in accounting for (or recognizing the effects of) reference rate reform on financial reporting. Companies can apply the ASU immediately, however, the guidance will only be available until December 31, 2022. We are currently evaluating the impact that adopting this new accounting standard would have on our condensed consolidated financial statements and related disclosures.
In January 2021, the FASB issued ASU 2021-01, Reference Rate Reform (Topic 848): Scope. The amendments in ASU 2021-01 provide optional expedients to the current guidance on contract modification and hedge accounting from the expected market transition from LIBOR and other interbank offered rates to alternative reference rates. The guidance generally can be applied to applicable contract modifications through December 31, 2022. We are currently evaluating the impact that adopting this new accounting standard would have on our condensed consolidated financial statements and related disclosures.
Codification Improvements
In October 2020, the FASB issued ASU 2020-10, Codification Improvements. The amendments in this ASU represent changes to clarify the ASC, correct unintended application of guidance, or make minor improvements to the ASC that are not expected to have a significant effect on current accounting practice or create a significant administrative cost to most entities. ASU 2020-10 is effective for annual periods beginning after December 15, 2020 and interim periods within those annual periods, with early adoption permitted. The amendments in this ASU should be applied retrospectively. We adopted this guidance as of January 1, 2021 and the adoption did not have an impact on our condensed consolidated financial statements.
Business Combinations
In October 2021, the FASB issued ASU 2021-08, Business Combinations (Topic 805): Accounting for Contract Assets and Contract Liabilities from Contracts with Customers, which requires entities to apply Topic 606 to recognize and measure contract assets and contract liabilities in a business combination. ASU 2021-08 is effective for our fiscal year beginning after December 15, 2022. We are currently evaluating the impact that adopting this new accounting standard would have on our condensed consolidated financial statements.
3. REVENUE FROM CONTRACTS WITH CUSTOMERS
Disaggregation of Revenue
Our reportable segments for the three and nine months ended September 30, 2021 were U.S. Regions, U.S. Federal, Canada and Non-Solar Distributed Generation (“Non-Solar DG”). On January 1, 2021, we changed the structure of our internal organization and our U.S. Regions segment now includes our U.S.-based enterprise energy management services previously included in our “All Other” segment. As a result, previously reported amounts have been reclassified for comparative purposes.

Total contract liabilities$40,302 $32,178 
(1) Performance obligations that are expected to be completed beyond the next twelve months and are included in other liabilities in the condensed consolidated balance sheets.
The increase in contract assets for the nine months ended September 30, 2021 was primarily due to revenue recognized of $414,049 offset by billings of $422,565. Contract assets also increased due to reclassifications, primarily from contract liabilities as a result of timing of customer payments. 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, 2021, we recognized revenue of $161,037 that was previously included in the beginning balance of contract liabilities and billed customers $123,891. Changes in contract liabilities are also driven by reclassifications to or from contract assets as a result of timing of customer payments.
The decrease in contract assets for the nine months ended September 30, 2020 was primarily due to billings of approximately $464,712, partially offset by revenue recognized of $434,709. The increase in contract liabilities was primarily driven by the receipt of advance payment from customers, and related billings, exceeding reductions from the recognition of revenue as performance obligations were satisfied. For the nine months ended September 30, 2020, we 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.

Performance Obligations
Our remaining performance obligations (“backlog”) represent the unrecognized revenue value of our contract commitments. At September 30, 2021, we had backlog of $1,893,740 of which approximately 33% is anticipated to be recognized as revenue in the next twelve months. The remaining performance obligations primarily relate to the energy efficiency and renewable energy construction projects, including long-term operations and maintenance (“O&M”) services related to these projects. The long-term services have varying initial contract terms, up to 25 years.

During the three months ended September 30, 2020, there was a triggering event which caused us to perform an impairment analysis on an energy asset group within the Non-solar DG segment. This triggering event was related to a decision by the applicable state environmental agency to discontinue an environmental permit. This action materially modified the obligation of the landfill owner to continue maintaining the wellfield, therefore, we plan to decommission the impacted landfill gas plant. As a result, we recorded an impairment charge of $1,901, which fully impaired this asset group. The impairment charge is included in

Sale-leasebacks
We entered into a fifth amendment dated March 22, 2021 to our August 2018 agreement for a long-term financing facility and increased the maximum funding amount from $150,000 up to $350,000 and extended the end date of the agreement from May 23, 2021 to March 31, 2022. We sold and leased back three energy assets for $31,095 in cash proceeds under this facility during the nine months ended September 30, 2021. As of September 30, 2021, approximately $280,610 remained available under this lending commitment.
In July 2021, we entered into an amendment to our December 2020 long-term financing facility which increased our maximum commitment from $4,500 to $23,559 and extended the end date of the agreement to December 31, 2021. We sold and leased back one energy asset for $3,281 in cash proceeds under this facility during nine months ended September 30, 2021. As of September 30, 2021, approximately $15,936 remained available under this lending commitment.
These transactions are accounted for as failed sales and are classified as long-term financing facilities. See Note 7 for additional information.
Net gains from amortization expense recognized in cost of revenues relating to deferred gains and losses in connection with our sale-leaseback agreements were $57 and $57 for the three months ended September 30, 2021 and 2020, respectively, and $172 and $170 for the nine months ended September 30, 2021 and 2020, respectively.

(3) Financing lease liabilities are sale-leaseback arrangements under previous guidance. See Note 6 for additional disclosures.

Senior Secured Revolving Credit Facility
On June 22, 2021, we entered into the second amendment to the fourth amended and restated bank credit facility we have syndicated with three banks, which increased the amount of the revolving commitment by the lenders under the credit facility by $65,000 and included the following amendments:
increased the aggregate amount of the revolving commitments from $115,000 to $180,000 through the existing June 28, 2024 maturity date,
increased the total funded debt to EBITDA covenant ratio from a maximum of 3.25 to 3.50, and
decreased the Eurocurrency rate floor from 1% to 0%.
We accounted for this amendment as a modification and at closing we incurred $78 in lender fees which were reflected as debt discount. The unamortized debt discount and issuance costs are being amortized over the remaining term of the amended agreement.
October 2020 Term Loan Modification
In October 2020, we entered into an amended and restated credit agreement with a bank primarily to increase the commitments under the existing credit agreement and add projects eligible for financing. The new credit agreement increased the commitment from $28,500 to $35,000 and included an option for the lender to increase the commitment by up to an additional $15,000 for a total not to exceed $50,000.
During the nine months ended September 30, 2021, the lender increased its commitment by the remaining $15,000 and we received net proceeds of $14,848. The quarterly payments consist of $1,250 in principal plus an additional principal prepayment based on project cash flows in addition to interest to be paid through the earlier of maturity, March 2026, or when the principal balance is paid in full. We accounted for this amendment as a modification and at closing we incurred $150 in lender fees which were reflected as debt discount and $2 in third-party fees which were expensed in selling, general and administrative expenses during the nine months ended September 30, 2021. The unamortized debt discount and issuance costs from the October 2020 loan modification are being amortized over the remaining term of the amended agreement. The balance of the loan outstanding as of September 30, 2021 was $42,833, net of unamortized debt discount and issuance costs.
Construction Revolvers
In June 2020, we entered into a revolving credit agreement with a bank, with an aggregate borrowing capacity of $100,000 for use in financing the construction cost of our owned projects. In March 2021, we entered into a third amendment to this agreement to

extend this facility from May 2021 to March 2022. All remaining unpaid amounts outstanding under the facility are due at that time.
During the nine months ended September 30, 2021, we closed on $14,013 in funding for four additional projects under this facility and drew down an additional $6,132 for existing projects. The balance of this construction revolver as of September 30, 2021 was $35,102, net of unamortized debt issuance costs and funds of $64,677 were available for borrowing under this facility.
We also have funds of $24,145 available for borrowing under our July 2020 construction revolver. In July 2021, two projects financed under this revolver failed to achieve commercial operations date (“COD”) on a timely basis; however, we received a limited waiver and an extension of COD for both projects from our lender, which cured the resulting event of default retroactively.

July 2021 Term Notes
On July 27, 2021, we entered into a $44,748 non-recourse debt agreement with a group of lenders. The financing facility consists of gross proceeds of $40,683 in senior secured first lien term notes due March 2046 (“Senior Notes”), gross proceeds of $4,065 in floating rate senior secured second lien term notes due March 2030 (“Second Lien Notes”), and a shelf facility of up to $60,000 available until July 2024. There were no notes issued under the shelf facility at September 30, 2021 and the lenders, in their sole discretion, have the right to approve or deny our funding requests.
The Senior Notes bear interest at a fixed rate of 3.25% per annum, are payable quarterly commencing September 30, 2021, and require that the project’s debt service coverage ratio for both the historical 12-month and projected 12-month periods at each payment date equal or exceed 1.2 to 1.0.
The Second Lien Notes bear a floating rate equal to the applicable LIBOR rate plus 3.50% from July 27, 2021 to July 26, 2025 and on July 27, 2025 the rate increases to the applicable LIBOR rate plus 3.75%. The Second Lien Notes are payable on each quarterly payment date commencing September 30, 2021, as specified in the debt agreement.
The agreement also requires us to maintain six months of scheduled payments of principal and interest as the minimum debt service reserve and to make additional principal prepayments based on project cash flows and certain other conditions through the earlier of maturity or when the principal balance is paid in full.
At closing, we incurred $957 in lender fees and debt issuance costs. In connection with the Senior Notes, we recorded a derivative instrument for make-whole provisions with an initial value of $5,164, which is included in debt discount. See Note 11 for additional information. The aggregate balance of the Senior Notes and Second Lien Notes as of September 30, 2021 was $37,411, net of unamortized debt discount and issuance costs.
8. INCOME TAXES
We recorded a (benefit) provision for income taxes of $(1,192) and $3,100 for the three months ended September 30, 2021 and 2020, respectively. The estimated effective annualized tax rate impacted by the period discrete items is a benefit of 6.2% for the three months ended September 30, 2021, compared to a provision of 14.9% of estimated effective annualized tax rate for the three months ended September 30, 2020.
We recorded a (benefit) provision for income taxes of $(883) and $597 for the nine months ended September 30, 2021 and 2020, respectively. The estimated effective annualized tax rate impacted by the period discrete items is a benefit of 1.8% for the nine months ended September 30, 2021, compared to a provision of 1.8% of estimated effective annualized tax rate for the nine months ended September 30, 2020.
The principal reasons for the difference between the statutory rate and the estimated annual effective rate for 2021 were the effects of investment tax credits which we are entitled from solar plants placed into service or are forecasted to be placed into service during 2021, the tax deductions related to the Section 179D deduction, the deduction of compensation expense associated with certain employee stock options, and tax basis adjustments on certain partnership flip transactions.
The principal reason for the difference between the statutory rate and the estimated annual effective rate for 2020 were the effects of investment tax credits to which we are entitled from solar plants which were placed into service during 2020, tax deductions related to the Section 179D deduction, tax basis adjustments on certain partnership flip transactions, and tax rate benefits associated with the net operating loss carryback made possible by the passing of the COVID-19 CARES Act on March 27, 2020.

Under GAAP accounting rules deferred taxes are shown on a net basis in the condensed consolidated financial statements based on taxing jurisdiction. Under the guidance, we have recorded long term deferred tax assets and deferred tax liabilities based on the underlying jurisdiction in the accompanying condensed consolidated balance sheets.
The following table sets forth the total amounts of gross unrecognized tax benefits:
Gross Unrecognized
Tax Benefits
Balance, December 31, 2020$600 
Additions for prior year tax positions200 
Balance, September 30, 2021$800 
The amount of unrecognized tax benefits that, if recognized, would favorably affect the effective income tax rate in any future periods was $400 at September 30, 2021 and $190 at December 31, 2020 (net of the federal benefit on state amounts).
9. COMMITMENTS AND CONTINGENCIES
From time to time, we issue letters of credit and performance bonds with our third-party lenders, to provide collateral.
Legal Proceedings
On November 6, 2017, we were served with a complaint filed by a customer against nine contractors, including us, claiming both physical damages to the customer’s tangible property and damages caused by various alleged defects in the design of the project through negligent acts and/or omissions, breaches of contract and breaches of the “implied warranty of good and workmanlike manner.” A mediation was held in January 2021, at which time we made an offer to settle the case, in an amount which we believe would be covered by our insurance. The trial has been set for April 2022 and both parties are taking discovery. Although the customer rejected our offer, both parties have agreed to continue to negotiate a settlement and we expect to re-engage in negotiation discussions as the trial date draws nearer. We believe that it is probable that a loss will be incurred and, therefore, have accrued a reasonable estimate of the loss, which is included in accrued expenses and other current liabilities in our condensed consolidated balance sheets as of September 30, 2021 and December 31, 2020. In addition, we accrued a loss recovery from insurance proceeds as we believe the receipt of such proceeds is probable. The loss recovery accrual is included in prepaid expenses and other current assets in our consolidated balance sheets as of September 30, 2021 and December 31, 2020. There were no changes to our estimate during the nine months ended September 30, 2021.
We are involved in a variety of other claims and other legal proceedings generally incidental to our normal business activities. While the outcome of any of these proceedings cannot be accurately predicted, we do not believe the ultimate resolution of any of these existing matters would have a material adverse effect on our financial condition or results of operations.
Commitment as a Result of an Acquisition
In August 2018, we completed an acquisition which provided for a revenue earn-out contingent upon the acquired business meeting certain cumulative revenue targets over 5 years from the acquisition date. The fair value was $678 as of September 30, 2021 and December 31, 2020 and is included in other liabilities on the condensed consolidated balance sheets. The contingent consideration will be paid annually in May, if any of the cumulative revenue targets are achieved. No payments have been made to date.
10. FAIR VALUE MEASUREMENT
We recognize our financial assets and liabilities at fair value on a recurring basis (at least annually). Fair value is defined as the price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Three levels of inputs that may be used to measure fair value are as follows:
Level 1: Inputs are based on unadjusted quoted prices for identical instruments traded in active markets. 
Level 2: Inputs are based on quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active, and model-based valuation techniques for which all significant assumptions are

Table of Contents

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
(In thousands) (Unaudited) (Continued)
observable in the market or can be corroborated by observable market data for substantially the full term of the assets or liabilities. 
Level 3: Inputs are generally unobservable and typically reflect management’s estimates of assumptions that market participants would use in pricing the asset or liability. The fair values are therefore determined using model-based techniques that include option pricing models, discounted cash flow models, and similar techniques. 
The following table presents the input level used to determine the fair values of our financial instruments measured at fair value on a recurring basis:

Fair ValueCarrying ValueFair ValueCarrying Value
Long-term debt (Level 2) $382,592 $378,884 $363,460 $357,536 
The fair value of our long-term debt was estimated using discounted cash flows analysis, based on our current incremental borrowing rates for similar types of borrowing arrangements which are considered to be level two inputs. There have been no transfers in or out of level two or three financial instruments for the nine months ended September 30, 2021 and the year ended December 31, 2020.
We are also required to periodically measure certain other assets at fair value on a nonrecurring basis, including long-lived assets, goodwill and other intangible assets. We calculated the fair value used in our annual goodwill impairment analysis utilizing a discounted cash flow analysis and determined that the inputs used were level 3 inputs. There were no assets recorded at fair value on a non-recurring basis as of September 30, 2021 or December 31, 2020.

13. REDEEMABLE NON-CONTROLLING INTERESTS
Our subsidiaries with membership interests in the investment funds we formed have the right to elect to require the non-controlling interest holder to sell all of its membership units to our subsidiaries, a call option. Our investment funds also include rights for the non-controlling interest holder to elect to require our subsidiaries to purchase all of the non-controlling membership interests in the fund, a put option.
The call options are exercisable beginning on the date that specified conditions are met for each respective fund. The call option period for one of our investment funds began in March 2021. In September 2021 we finalized our purchase of the investor’s membership interest for $1,000 in cash and reclassified the remaining redeemable non-controlling interest balance to paid-in capital to reflect the additional contribution from us to our wholly-owned subsidiary.
The put options for the investment funds are exercisable beginning on the date that specified conditions are met for each respective fund.
We initially record our redeemable non-controlling interests at fair value on the date of acquisition and subsequently adjust to redemption value. At both September 30, 2021 and December 31, 2020 redeemable non-controlling interests were reported at their carrying values, as the carrying value at each reporting period was greater than the estimated redemption value.
14. EQUITY AND EARNINGS PER SHARE
Equity Offering
On March 9, 2021, we closed on an underwritten public offering of 2,500 shares of our Class A common stock at a public offering price of $44.00 per share. Net proceeds from the offering were $104,326, after deducting offering costs of $5,674. On March 15, 2021, we closed on the underwriters’ option to purchase 375 additional shares of Class A common stock from us, resulting in net proceeds of $15,758 after deducting offering costs of $742. We used $80,000 of the net proceeds to repay in full the outstanding U.S. dollar balance under our senior secured revolving credit facility.
In the offering, selling shareholders sold 805 shares our Class A Common Stock at a public offering price of $44.00 per share, less the underwriting discount. We did not receive any proceeds from the sale of the shares by the selling stockholders.

Stock Option Grants
During the nine months ended September 30, 2021, we granted 946 common stock options to certain employees under our 2020 Stock Incentive Plan, which have a contractual life of ten years and vest over a five-year period. We did not grant awards to individuals who were not either an employee or director of ours during the nine months ended September 30, 2021 and 2020.
16. BUSINESS SEGMENT INFORMATION
Our reportable segments for the three and nine months ended September 30, 2021 were U.S. Regions, U.S. Federal, Canada and Non-Solar DG. On January 1, 2021, we changed the structure of our internal organization and our U.S. Regions segment now includes our U.S.-based enterprise energy management services previously included in our “All Other” segment. As a result, previously reported amounts have been reclassified for comparative purposes.
Our U.S. Regions, U.S. Federal and Canada segments offer energy efficiency products and services which include the design, engineering and installation of equipment and other measures to improve the efficiency and control the operation of a facility’s energy infrastructure, renewable energy solutions and services and the development and construction of small-scale plants that

Ameresco owns or develops for customers that produce electricity, gas, heat or cooling from renewable sources of energy and O&M services.
Our Non-Solar DG segment sells electricity, processed renewable gas fuel, heat or cooling, produced from renewable sources of energy, other than solar, and generated by small-scale plants that we own and O&M services for customer-owned small-scale plants.
The “All Other” category includes enterprise energy management services, other than the U.S.-based portion; consulting services, energy efficiency products and services outside of the U.S. and Canada; and the sale of solar PV energy products and systems which we refer to as integrated-PV.
These segments do not include results of other activities, such as corporate operating expenses not specifically allocated to the segments. Certain reportable segments are an aggregation of operating segments.

18. SUBSEQUENT EVENT
On October 21, 2021, we entered into a Turnkey Engineering, Procurement, Construction and Maintenance Agreement (the “EPCM Agreement”) with a customer and also entered into three purchase orders under the EPCM Agreement providing for us to design and build battery energy storage system facilities at three locations with a capacity of 537.5 megawatts in the aggregate. The engineering, procurement and construction price is approximately $892 million, in the aggregate, subject to customary potential adjustments for changes in the work.
We are obligated under the EPCM Agreement to achieve substantial completion of all three facilities, subject to extension for customary force majeure events and customer-caused delays, no later than August 1, 2022 (the “Guaranteed Completion Date”). If we fail to achieve substantial completion of any of the facilities by the Guaranteed Completion Date, as extended, we are obligated to pay liquidated damages. In addition, we provided availability and capacity guarantees under the EPCM Agreement, failure of which entitles the customer to liquidated damages.

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

Key Factors and Trends
COVID-19 Update
Fiscal year 2020 was marked with unrivaled global challenges, including the public health and economic downturn caused by the COVID-19 pandemic. During the first half of 2020, after COVID-19 was declared a pandemic by the World Health Organization, we experienced some delays in our project award conversions and some construction slowdowns due to shelter-in-place restrictions; however, the opportunities to reduce emissions and limit the effects of climate change remained. We responded to the pandemic by ensuring the health and safety of our employees. We implemented a seamless transition to remote operations for many months, and, while following all CDC guidelines, continued front-line work at our essential facilities.
The resurgence of COVID-19 and its variants has caused some governments to extend travel and other restrictions. On September 9, 2021, President Biden issued an Executive Order requiring COVID-19 vaccinations for Federal employees. As a result, we are in the process of implementing this mandate for our employees and subcontractors who work in our Federal business segment. The vaccine mandate could result in a potential loss of employees or subcontractors who have not been vaccinated. See Part II, Item 1A. Risk Factors in this Form 10-Q, for discussion of risks associated with the potential adverse effects on our workforce of the federal government vaccine mandate for employees, contractors, and subcontractors that service federal contracts and the OSHA requirement on our workforce.
We continue to monitor the impact of COVID-19 on our results and liquidity. The impact to our future results, however, remains uncertain and will depend on a number of factors, including, but not limited to, the duration and severity of the pandemic, its impact on our customers, and business and workforce disruptions.
Supply Chain Disruptions
During the three months ended September 30, 2021, we experienced supply chain disruptions resulting in delays in the timely delivery of material to customer sites. This negatively impacted our results of operations during the three months ended September 30, 2021 as our Project revenues decreased 10% from the same period last year. We expect this trend to continue into 2022.
The Energy Act of 2020
On December 27, 2020, the President signed the Consolidated Appropriations Act, 2021 into law, a legislative package that included the Energy Act of 2020, reauthorizing a number of U.S. Department of Energy programs, with a $2.3 trillion spending bill containing appropriations for fiscal year 2021, COVID-19 relief funds, and extensions of a number of expiring tax incentives important to the energy sector. It includes $35 billion in energy research and development programs, a two-year extension of the 26% Investment Tax Credit (“ITC”) rate for solar power that will retain the current 26% credits for solar projects that begin construction through the end of 2022. The 26% rate for ITC for solar projects was set to expire at the end of 2020. The Energy Act of 2020 also made the Section 179D Energy Efficient Commercial Building Deduction permanent under the tax code.
The Coronavirus Aid, Relief, and Economic Security Act (“CARES Act”)
On March 27, 2020, the U.S. government enacted the CARES Act which includes modifications to the limitation on business interest expense and net operating loss provisions, and provides a payment delay of employer payroll taxes during 2020 after the date of enactment. The payment of $4.5 million of our employer payroll taxes otherwise due in 2020 has been delayed with 50% due by December 31, 2021 and the remaining 50% by December 31, 2022. The CARES Act permitted 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).
Effects of Seasonality
We are subject to seasonal fluctuations and construction cycles, particularly in climates that experience colder weather during the winter months, such as the northern United States and Canada, or at educational institutions, where large projects are typically carried out during summer months when their facilities are unoccupied. In addition, government customers, many of which have fiscal years that do not coincide with ours, typically follow annual procurement cycles and appropriate funds on a fiscal-year basis even though contract performance may take more than one year. Further, government contracting cycles can be affected by the timing of, and delays in, the legislative process related to government programs and incentives that help drive demand for energy efficiency and renewable energy projects. As a result, our revenues and operating income in the third and fourth quarter are typically higher, and our revenues and operating income in the first quarter are typically lower, than in other quarters of the year. As a result of such fluctuations, we may occasionally experience declines in revenues or earnings as compared to the immediately preceding quarter, and comparisons of our operating results on a period-to-period basis may not be meaningful.

Our annual and quarterly financial results are also subject to significant fluctuations as a result of other factors, many of which are outside our control. See “Our business is affected by seasonal trends and construction cycles, and these trends and cycles could have an adverse effect on our operating results.” in Item 1A, Risk Factors of our 2020 Annual Report.
Stock-based Compensation
During the nine months ended September 30, 2021, we granted 945,500 common stock options to certain employees under our 2020 Stock Incentive Plan. As a result, our unrecognized stock-based compensation expense increased from $12.1 million at December 31, 2020 to $27.8 million at September 30, 2021 and is expected to be recognized over a weighted-average period of 3.0 years. See Note 15 “Stock-based Compensation” for additional information.
Backlog and Awarded Projects
The following table presents our backlog:
As of September 30,
(In Thousands)20212020
Project Backlog
Fully-contracted backlog$778,320 $1,033,650 
Awarded, not yet signed customer contracts1,585,470 1,211,300 
Total project backlog$2,363,790 $2,244,950 
12-month project backlog$551,570 $605,880 
O&M Backlog
Fully-contracted backlog$1,115,420 $1,120,820 
12-month O&M backlog$66,250 $59,990 
In late October 2021, we announced an $892 million contract to provide a multi-site battery energy storage system. This design-build contract significantly increased our fully-contracted backlog and we anticipate that it will be an important driver of our results through 2022.
Total project backlog represents energy efficiency projects that are active within our sales cycle. Our sales cycle begins with the initial contact with the customer and ends, when successful, with a signed contract, also referred to as fully-contracted backlog. Our sales cycle recently has been averaging 18 to 42 months. Awarded backlog is created when a potential customer awards a project to Ameresco following a request for proposal. Once a project is awarded but not yet contracted, we typically conduct a detailed energy audit to determine the scope of the project as well as identify the savings that may be expected to be generated from upgrading the customer’s energy infrastructure. At this point, we also determine the subcontractor, what equipment will be used, and assist in arranging for third party financing, as applicable. Recently, awarded projects have been taking an average of 12 to 24 months to result in a signed contract and convert to fully-contracted backlog. It may take longer, as it depends on the size and complexity of the project. Historically, approximately 90% of our awarded backlog projects have resulted in a signed contract. After the customer and Ameresco agree to the terms of the contract and the contract becomes executed, the project moves to fully-contracted backlog. The contracts reflected in our fully-contracted backlog typically have a construction period of 12 to 36 months and we typically expect to recognize revenue for such contracts over the same period.
Our O&M backlog represents expected future revenues under signed multi-year customer contracts for the delivery of O&M services, primarily for energy efficiency and renewable energy construction projects completed by us for our customers.
We define our 12-month backlog as the estimated amount of revenues that we expect to recognize in the next twelve months from our fully-contracted backlog. See “We may not recognize all revenues from our backlog or receive all payments anticipated under awarded projects and customer contracts” and “In order to secure contracts for new projects, we typically face a long and variable selling cycle that requires significant resource commitments and requires a long lead time before we realize revenues” in Item 1A, Risk Factors in our 2020 Annual Report.

All financial result comparisons made below are against the same prior year period unless otherwise noted.
Our results of operations for the three months ended September 30, 2021 were due to the following:
Revenues: total revenues for the three months ended September 30, 2021 decreased over 2020 primarily due to a $21.4 million, or 10%, decrease in our project revenues primarily due to construction delays attributed to COVID-related protocols and supply chain disruptions resulting in delays in the timely delivery of materials to customer sites. This was partially offset by an $8.9 million, or 29%, increase in our energy asset revenue attributed to the continued growth of our operating portfolio, strong renewable gas production and higher pricing on renewable identification numbers (“RINs”) generated from certain non-solar distributed generation assets in operation and a $2.1 million increase in O&M revenue.
Cost of Revenues and Gross Profit: the decrease in cost of revenues is primarily due to the decrease in project revenues described above. Gross profit increased as our revenue mix continued to shift towards our higher margin Energy Assets business.
Selling, General and Administrative Expenses (“SG&A”): SG&A expenses for the three months ended September 30, 2021 increased over 2020 primarily due to higher net salaries and benefits of $4.5 million as a result of increased headcount and higher health insurance costs driven by an increase in employee claims. The increase is also due to higher professional fees of $1.4 million and increased impairment charges of $0.9 million. SG&A in 2020 also included a recovery of a fully-reserved bad debt of $1.0 million.
Other Expenses, Net: Other expenses, net, includes gains and losses from derivatives transactions, foreign currency transactions, interest expense, interest income, amortization of financing costs and certain government incentives. Other expenses, net for the three months ended September 30, 2021 increased over 2020 primarily due to higher foreign currency transaction loss of $0.6 million, higher interest expense of $0.5 million partially offset by increased government incentive income of $0.3 million.
Income before Income Taxes: the increase is due to reasons described above.
Income Tax (Benefit) Provision: the provision for income taxes is based on various rates set by federal, state, provincial and local authorities and is affected by permanent and temporary differences between financial accounting and tax reporting requirements. The effective tax rate was lower in 2021 as compared to 2020 primarily due to higher investments in solar projects eligible for the ITC, higher availability of the Section 179D deduction on energy

improvements on government owned buildings, and higher compensation deductions related to employee stock option exercises.
Net Income and Earnings Per Share: Net income attributable to common shareholders decreased as the results for the three months ended September 30, 2021 reflect a non-cash downward adjustment of $2.9 million and 2020 reflects a non-cash upward adjustment of $2.3 million related to non-controlling interest activities. Basic earnings per share for the three months ended September 30, 2021 was $0.34, a decrease of $0.08 per share compared to the same period of 2020. Diluted earnings per share for 2021 was $0.33, a decrease of $0.08 per share compared to last year. The equity offering in March 2021 increased the weighted average shares outstanding by 2,875,000, which lowered basic and diluted earnings per share by $0.02 per share.

Our results of operations for the nine months ended September 30, 2021 reflect year-over-year growth in terms of revenues, operating income, and net income attributable to common shareholders due to the following:
Revenues: Revenues for the nine months ended September 30, 2021 increased over 2020 primarily due to a $51.2 million, or 10%, increase in our project revenue attributable to the timing of revenue recognized as a result of the phase of active projects versus the prior year and a $22.2 million, or 25%, increase in our energy asset revenue for the same reasons noted above.
Cost of Revenues and Gross Profit: the increase in cost of revenues is primarily due to the increase in project revenues described above. The increase in gross profit as a percentage of revenue increased as our revenue mix continued to shift towards our higher margin Energy Assets business.
Selling, General and Administrative Expenses: SG&A expenses for the nine months ended September 30, 2021 increased over 2020 primarily due higher net salaries and benefits of $10.0 million for the same reasons noted previously, higher professional fees of $1.9 million and higher impairment charges of $0.9 million. SG&A in 2020 also included recoveries of fully-reserved bad debts of $1.1 million.
Other Expenses, Net: Other expenses, net for the nine months ended September 30, 2021 increased over 2020 primarily due to higher mark to market losses realized from derivatives of $0.9 million, higher foreign currency transaction losses of $0.7 million, and lower government incentive income of $0.5 million partially offset by lower interest expenses of $1.8 million.
Income before Income Taxes: the increase is due to reasons described above.
Income Tax Benefit: The effective tax rate was lower in 2021 as compared to 2020 primarily due to higher investments in solar projects eligible for the ITC, higher availability of the Section 179D deduction on energy improvements on government owned buildings, and higher compensation deductions related to employee stock option exercises.
Net Income and Earnings Per Share: For the nine months ended September 30, 2021 basic earnings per share was $0.83, an increase of $0.19 per share compared to 2020, and diluted earnings per share was $0.81, an increase of $0.19 per share compared to last year. The equity offering increased the weighted average shares outstanding by approximately 2,158,000, which lowered basic and diluted earnings per share by $0.04 per share. Earnings per share in the remaining quarter of this year will continue to be impacted because the weighted average shares outstanding in the year-to-date calculations will reflect a greater proportion of the 2,875,000 shares sold. The results for the nine months ended

Business Segment Analysis
Our reportable segments for the three and nine months ended September 30, 2021 were U.S. Regions, U.S. Federal, Canada and Non-Solar DG. On January 1, 2021, we changed the structure of our internal organization and our U.S. Regions segment now includes our U.S.-based enterprise energy management services previously included in our “All Other” segment. As a result, previously reported amounts have been reclassified for comparative purposes. These segments do not include results of other activities, such as corporate operating expenses not specifically allocated to the segments. See Note 16 “Business Segment Information” for additional information about our segments.

All financial result comparisons made below relate to both the three and nine month periods and are against the same prior year period unless otherwise noted.
U.S. Regions: the increase is primarily due to an increase in project revenue attributable to the timing of revenue recognized as a result of the phase of active projects versus the prior year, an increase in O&M revenue and higher energy asset revenue attributed to the growth and performance of our solar asset portfolio. Although revenues increased year-over-year, they were lower than anticipated due to supply chain and COVID-related delays that impacted material deliveries, labor and scheduling.
U.S. Federal: the decrease for the three months ended September 30, 2021 is primarily due to a 21% decrease in project revenue due to the timing of revenue recognized as a result of the phase of active projects. The increase for the nine months ended September 30, 2021 is primarily attributable to similar timing considerations which benefited from accelerated timing of certain approvals and progress on customized equipment during the first half of the year.
Canada: the decrease for the three months ended September 30, 2021 is primarily due to a $1.0 million decrease in project revenues partially offset by increases in energy asset and other revenues. The increase for the nine months ended September 30, 2021 is primarily due to favorable foreign exchange rates.
Non-Solar DG: the increase is primarily attributed to higher energy asset revenues resulting from the continued growth of our operating portfolio, increased renewable gas production levels and higher pricing on RINs generated from certain non-solar distributed generation assets in operation.
All Other: All other revenues for the three months ended September 30, 2021 decreased over 2020 primarily due to an $2.6 million decrease in project revenues as a result of the phase of active projects versus the prior year, partially offset by a $1.0 million increase in integrated-PV revenue. All other revenues for the nine months ended September 30, 2021 increased over 2020 primarily due to an increase in project revenues combined with favorable foreign exchange rates in the United Kingdom, as well as an increase in other revenue.

U.S. Regions: the increase is primarily due to the increase in revenues described above, lower interest expense and higher government incentive income, partially offset by higher net salaries and benefits.
U.S. Federal: the decrease for the three months ended September 30, 2021 is primarily due to the decrease in revenues described above, as well as higher net salaries and benefits and depreciation and amortization. The increase for the nine months ended September 30, 2021 is due to higher revenues and lower interest expense partially offset by higher net salaries and benefits.
Canada: the decrease for the three months ended September 30, 2021 is primarily due to lower revenues, partially offset by mark to market gains realized from derivatives compared to mark to market losses in 2020. The increase for the nine months ended September 30, 2021 is primarily due to the increase in revenues described above, mark to market gains realized from derivatives partially offset by higher project development costs.
Non-Solar DG: the increase is primarily due to the higher contribution attributed to the increase in higher margin energy asset revenue described above partially offset by higher mark to market losses and impairment charges.
All Other: the decrease for the three months ended September 30, 2021 is primarily due to lower revenues and SG&A in 2020 also included a recovery of a fully reserved bad debt of $1 million. The decrease for the nine months ended September 30, 2021 is due to higher project development costs, the 2020 recovery of bad debt partially offset by higher revenues noted above.
Unallocated corporate activity includes all corporate level selling, general and administrative expenses and other expenses not allocated to the segments. We do not allocate any indirect expenses to the segments. Corporate activity increased primarily due to higher net salaries and benefit costs and increased professional fees, partially offset by lower interest expenses.

Liquidity and Capital Resources
Overview
Since inception, we have funded operations primarily through cash flow from operations, advances from Federal ESPC projects, our senior secured credit facility, and various forms of other debt. In addition, in March 2021, we completed an underwritten public offering of 2,875,000 shares of our Class A Common Stock, for total net proceeds of $120.1 million. See below, Note 7 “Debt and Financing Lease Liabilities”, and Note 14 “Equity and Earnings per Share” for additional information.
Working capital requirements, which can be susceptible to fluctuations during the year due to seasonal demands, generally result from revenue growth, our solar equipment purchase patterns, the timing of funding under various contracts, and payment terms for receivables and payables.
We expect to incur additional expenditures in connection with the following activities:
equity investments, project asset acquisitions and business acquisitions that we may fund from time to time
capital investment in current and future energy assets
We regularly monitor and assess our ability to meet funding requirements. We believe that cash and cash equivalents, working capital and availability under our revolving senior secured credit facility, combined with our access to credit markets, will be sufficient to fund our operations through at least November 2022 and thereafter. However, we continue to evaluate and take action, as necessary, to preserve adequate liquidity and ensure that our business can continue to operate during these uncertain

times. This may include limiting discretionary spending across the organization and re-prioritizing our capital projects amid the COVID-19 pandemic.
Sources of Liquidity
On March 9, 2021, we closed on an underwritten public offering of 2,500,000 shares of our Class A Common Stock at a public offering price of $44.00 per share. Net proceeds from the offering were $104.3 million, after deducting offering costs. On March 15, 2021, we closed on the underwriters’ option to purchase 375,000 additional shares of Class A common stock from us, resulting in net proceeds of $15.8 million, after deducting offering costs. In the offering, selling shareholders sold 805,000 shares of our Class A Common Stock at a public offering price of $44.00 per share, less the underwriting discount. We did not receive any proceeds from the sale of the shares by the selling stockholders. We used $80.0 million of the net proceeds to repay in full the outstanding U.S. dollar balance under our senior secured revolving credit facility. We intend to use the remaining proceeds for general corporate purposes, including potential tack on acquisitions, working capital and capital expenditures.
On June 22, 2021, we entered into an amendment to our senior secured revolving credit facility with three banks which increased the amount of the revolving commitment by the lenders under the credit facility from $115.0 million to $180.0 million. The amendment also increased the total funded debt to EBITDA covenant ratio from a maximum of 3.25 to 3.50, and decreased the Eurocurrency rate floor from 1% to 0%. At September 30, 2021, funds of $151.2 million were available for borrowing under this facility.
During the nine months ended September 30, 2021, a lender increased its commitment by the remaining $15.0 million available under a term loan and we received net proceeds of $14.8 million. The quarterly payments consist of $1.25 million in principal plus an additional principal prepayment based on project cash flows in addition to interest to be paid through the earlier of maturity, March 2026, or when the principal balance is paid in full. The balance of this term loan as of September 30, 2021 was $42.8 million.
During the nine months ended September 30, 2021, we also closed on $14.0 million in funding for four additional projects under a construction revolver and drew an additional $6.1 million for existing projects. The balance of this construction revolver at September 30, 2021 was $35.1 million and funds of $64.7 million were available for borrowing under this facility. We also have funds of $24.1 million available for borrowing under another construction revolver. In July 2021, two projects financed under this revolver failed to achieve commercial operations date (“COD”) on a timely basis; however, we received a limited waiver and an extension of COD for both projects from our lender, which cured the resulting event of default retroactively.
We also utilize long-term financing facilities, accounted for as failed sale lease-backs, to finance our energy assets. During the nine months ended September 30, 2021, we sold and leased back three energy assets for $31.1 million in cash under our August 2018 facility and at September 30, 2021, approximately $280.6 million remained available under this lending commitment. In July 2021, we entered into an amendment to our December 2020 long-term financing facility which increased our maximum commitment from $4.5 million to $23.6 million and extended the end date of the agreement to December 31, 2021.
In July 2021, we entered into $44.7 million non-recourse debt agreement with a group of lenders. The financing facility consists of gross proceeds of $40.7 million in 25-year 3.25% senior secured first lien fixed rate term notes (“Senior Notes”), gross proceeds of $4.1 million in 9-year floating rate senior secured second lien term notes, and a shelf facility of up to $60.0 million available until July 2024. There were no notes issued under the shelf facility as of September 30, 2021 and the lenders, in their sole discretion, have the right to approve or deny our funding requests.
We are required to make quarterly principal and interest payments as specified in the agreements. The Senior Notes require that the project’s debt service coverage ratio for both the historical 12-month and projected 12-month periods at the payment date equal or exceed 1.2 to 1.0. The agreement also requires us to maintain six months of scheduled payments of principal and interest as the minimum debt service reserve and to make additional principal prepayments based on project cash flows and certain other conditions through the earlier of maturity or when the principal balance is paid in full. At closing, we incurred $1.0 million in lender fees and debt issuance costs and in connection with the Senior Notes, we recorded a derivative instrument for make-whole provisions with an initial value of $5.2 million, which is included in debt discount. The aggregate balance of these term notes as of September 30, 2021 was $37.4 million, net of unamortized debt discount and issuance costs.

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

Effect of exchange rate changes on cash118 (465)583 
Total net cash flows$(5,059)$(6,357)$1,298 
Our service offering also includes the development, construction, and operation of small-scale renewable energy plants. Small-scale renewable energy projects, or energy assets, can either be developed for the portfolio of assets that we own and operate or designed and built for customers. Expenditures related to projects that we own are recorded as cash outflows from investing activities. Expenditures related to projects that we build for customers are recorded as cash outflows from operating activities as cost of revenues.
Cash Flows from Operating Activities
Our cash flows from operating activities decreased from last year primarily due to an increase of $188.0 million in Federal ESPC receivables, compared to $160.2 million in 2020, which is consistent with the increase in our U.S. Federal revenues. Our operating cash flows reflect the Federal ESPC receivables as outflows as revenue is recognized during the construction or installation of projects and do not reflect any inflows from advances received from third-party lenders, which are recorded as cash inflows from financing activities. This was partially offset by higher net income of $50.6 million compared to $33.2 million last year.
Cash Flows from Investing Activities
During the nine months ended September 30, 2021 we invested $148.0 million in purchases of energy assets compared to $125.5 million in 2020.
We currently plan to invest approximately $70 million to $120 million in additional capital expenditures during the remainder of 2021, principally for the construction or acquisition of new renewable energy plants, the majority of which will be funded with project finance debt.
Cash Flows from Financing Activities
Our primary sources of financing in 2021 were net proceeds from our equity offering of $120.1 million, of which $80.0 million was used to pay our senior secured revolving credit facility, net proceeds from Federal ESPC projects and energy assets of $114.0 million and net proceeds from long-term debt financings of $118.2 million, partially offset by net payments on our senior secured revolving credit facility of $38.1 million and payments on long-term debt of $55.6 million.
Our primary sources of financing in 2020 were net proceeds received from Federal ESPC projects and energy assets of $196.0 million, net proceeds from our senior secured credit facility of $6.0 million, net proceeds from long-term debt financings of $40.6 million, partially offset by payments on long-term debt of $42.6 million.
We currently plan additional project financings of approximately $30 million to $80 million during the remainder of 2021 to fund the construction or the acquisition of new renewable energy plants as discussed above.
Critical Accounting Policies and Estimates
Preparing our consolidated financial statements in accordance with GAAP involves us making estimates and assumptions that affect reported amounts of assets and liabilities, net sales and expenses, and related disclosures in the accompanying notes at the date of our financial statements. We base our estimates on historical experience, industry and market trends, and on various other assumptions that we believe to be reasonable under the circumstances. However, by their nature, estimates are subject to various assumptions and uncertainties, and changes in circumstances could cause actual results to differ from these estimates, sometimes materially.

Income Taxes
We have reviewed all tax positions taken as of September 30, 2021 and increased our liability by $0.2 million for uncertain state tax positions taken during the nine months ended September 30, 2021. Including this adjustment, we believe our current tax reserves are adequate to cover all known tax uncertainties. We are evaluating The American Rescue Plan Act of 2021 passed into law on March 11, 2021 and at this time do not believe it will have a material impact on our accounting for income taxes.
Other than as noted above, there have been no material changes in our critical accounting estimates from those disclosed in Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations of our 2020 Form 10-K. In addition, refer to Note 2 “Summary of Significant Accounting Policies” for updates to critical accounting policies.
Recent Accounting Pronouncements
See Note 2, “Summary of Significant Accounting Policies” for a discussion of recent accounting pronouncements.
Item 3. Quantitative and Qualitative Disclosures About Market Risk
As of September 30, 2021, there have been no significant changes in market risk exposures that materially affected the quantitative and qualitative disclosures as described in Item 7A to our 2020 Annual Report.
Item 4. Controls and Procedures
Evaluation of Disclosure Controls and Procedures
Our management, with the participation of our principal executive officer and principal financial officer, evaluated the effectiveness of our disclosure controls and procedures, as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act, as of the end of the period covered by this quarterly report, or the evaluation date. Disclosure controls and procedures are designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported, within the time periods specified in the SEC’s rules and forms. Our management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving their objectives, and management necessarily applies its judgment in evaluating the cost-benefit relationship of possible controls and procedures. Our management, after evaluating the effectiveness of our disclosure controls and procedures as of the evaluation date, concluded that as of the evaluation date, our disclosure controls and procedures were effective at a reasonable level of assurance.
Changes in Internal Control over Financial Reporting
There were no changes in our internal control over financial reporting during our most recent fiscal quarter that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

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

Item 1A. Risk Factors
Our business is subject to numerous risks, a number of which are described below and under “Risk Factors” in Part I, Item 1A of our 2020 Annual Report and in Part II, Item 1A of our Quarterly Report on Form 10-Q for the quarter ended June 30, 2021. 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 2020 Annual Report and in our June 30, 2021 Form 10-Q 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 U.S. presidential executive order concerning mandatory COVID-19 vaccination of U.S.-based employees of companies that work on or in support of federal contracts could have a material adverse impact on our business and results of operations.
On September 9, 2021, President Biden issued an executive order requiring all employers with federal government contracts to ensure that their U.S.-based employees, contractors, and subcontractors, that work on or in support of federal contracts, are fully vaccinated by December 8, 2021. The executive order includes on-site and remote U.S.-based employees, contractors and subcontractors and it only permits limited exceptions for medical and religious reasons.
In addition, on September 9, 2021, President Biden announced that he has directed OSHA to develop an emergency temporary statement (“ETS”) mandating either the full vaccination or weekly testing of employees for employers with 100 or more employees. OSHA has not issued the ETS nor provided any additional information on its contents or requirements.
It is currently not possible to predict with certainty the impact the executive order or OSHA ETS will have on our workforce. As a federal government contractor, we are requiring all U.S. based employees, contractors and subcontractors that service or support our federal government contracts to be fully vaccinated by December 8, 2021. Employees who are not subject to this requirement and who are not fully vaccinated may be subject to the ETS that will require them to get a COVID-19 test at least once a week. Additional vaccine mandates may be announced in jurisdictions in which our businesses operate or by customers we serve. Our implementation of these requirements may result in attrition, including attrition of critically skilled workforce, and difficulty securing future workforce needs, which could have a material adverse effect on our business, financial condition, and results of operations.

Item 2. Unregistered Sales of Equity and Use of Proceeds
Stock Repurchase Program
We did not repurchase any shares of our common stock under our stock repurchase program authorized by the Board of Directors on April 27, 2016 (the “Repurchase Program”) during the three months ended September 30, 2021.


38

Table of Contents
Under the Repurchase Program, we are authorized to repurchase up to $17.6 million of our Class A common stock. As of September 30, 2021, there were shares having a dollar value of approximately $5.9 million that may yet be purchased under the Repurchase Program.
Stock repurchases may be made from time to time through the open market and privately negotiated transactions. The amount and timing of any share repurchases will depend upon a variety of factors, including the trading price of our Class A common stock, liquidity, securities laws restrictions, other regulatory restrictions, potential alternative uses of capital, and market and economic conditions. The Repurchase Program may be suspended or terminated at any time without prior notice and has no expiration date.
