Basis of Presentation
The accompanying Condensed Consolidated Financial Statements of ADES are unaudited and have been prepared in conformity with accounting principles generally accepted in the United States ("U.S. GAAP") and with Article 10 of Regulation S-X of the Securities and Exchange Commission. In compliance with those instructions, certain information and footnote disclosures normally included in annual consolidated financial statements prepared in accordance with U.S. GAAP have been condensed or omitted.
The unaudited Condensed Consolidated Financial Statements of ADES in this quarterly report ("Quarterly Report") are presented on a consolidated basis and include ADES and its wholly-owned subsidiaries (collectively, the "Company"). Also included within the unaudited Condensed Consolidated Financial Statements are the Company's unconsolidated equity investments;investments: Tinuum Group, Tinuum Services LLC ("Tinuum Services"), and GWN Manager, LLC ("GWN Manager"), which are accounted for under the equity method of accounting, and Highview Enterprises Limited (the "Highview Investment"), which is accounted for in accordance with U.S. GAAP applicable to equity investments that do not qualify for the equity method of accounting.
Results of operations and cash flows for the interim periods are not necessarily indicative of the results that may be expected for the entire year. All significant intercompany transactions and accounts were eliminated in consolidation for all periods presented in this Quarterly Report.
In the opinion of management, these Condensed Consolidated Financial Statements include all normal and recurring adjustments considered necessary for a fair presentation of the results of operations, financial position, stockholders' equity and cash flows for the interim periods presented. These Condensed Consolidated Financial Statements of ADES should be read in conjunction with the Company’s Annual Report on Form 10-K for the year ended December 31, 20182019 (the "2018"2019 Form 10-K"). Significant accounting policies disclosed therein have not changed, except as described later in Note 1.
Earnings (Loss) Per Share
Basic earnings (loss) per share is computed using the two-class method, which is an earnings allocation formula that determines earnings (loss) per share for common stock and any participating securities according to dividend and participating rights in undistributed earnings.earnings (losses). The Company's restricted stock awards ("RSA's") granted prior to December 31, 2016 contain non-forfeitable rights to dividends or dividend equivalents and are deemed to be participating securities. RSA's granted subsequent to December 31, 2016 do not contain non-forfeitable rights to dividends and are not deemed to be participating securities.
Under the two-class method, net income for the period is allocated between common stockholders and the holders of the participating securities based on the weighted-average number of common shares outstanding during the period, excluding participating, unvested RSA's ("common shares"), and the weighted-average number of participating unvested RSA's

participating, unvested RSA's ("common shares"), and the weighted-average number of participating, unvested RSA's outstanding during the period, respectively. The allocated, undistributed income for the period is then divided by the weighted-average number of common shares and participating, unvested RSA's outstanding during the period to arrive at basic earnings per common share and participating security for the period, respectively. Pursuant to U.S. GAAP, the Company has elected not to separately present basic or diluted earnings per share attributable to participating securities in the Condensed Consolidated Statements of Operations.
Diluted earnings (loss) per share is computed in a manner consistent with that of basic earnings per share, while considering other potentially dilutive securities. Potentially dilutive securities consist of both unvested, participating and non-participating RSA's, as well as outstanding options to purchase common stock ("Stock Options") and contingent performance stock units ("PSU's") (collectively, "Potential dilutive shares"). The dilutive effect, if any, for non-participating RSA's, Stock Options and PSU's is determined using the greater of dilution as calculated under the treasury stock method or the two-class method. Potential dilutive shares are excluded from diluted earnings per share when their effect is anti-dilutive. When there is a net loss for a period, all Potential dilutive shares are anti-dilutive and are excluded from the calculation of diluted loss per share for that period.
The following table sets forth the calculations of basic and diluted earnings (loss) per share:

For the nine months ended September 30, 2018, Stock Options to purchase 0.1 million shares, which vest based on the Company achieving specified performance targets, were outstanding, but were not included in the computation of diluted net income per share for a portion of this period because they were determined not to be contingently issuable.
Use of Estimates
The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. There have been no changes in the Company’s critical accounting estimates from those that were disclosed in the 20182019 Form 10-K.10-K except for assumptions regarding impairment of long-lived assets and the valuation of assets acquired and liabilities assumed in an asset acquisition. Actual results could differ from these estimates.
Due to the coronavirus ("COVID-19") pandemic, there has been uncertainty and disruption in the global economy and financial markets. Additionally, due to COVID-19, overall power generation and coal-fired power demand may change, which could also have a material adverse effect on the Company. The Company is not aware of any specific event or circumstance due to COVID-19 that would require an update to its estimates or judgments or a revision of the carrying values of its assets or liabilities through the date of this Quarterly Report. These estimates may change as new events occur and additional information is obtained. Actual results could differ materially from these estimates under different assumptions or conditions.
Risks and Uncertainties
The Company’s earnings are significantly affected by equity earnings it receives from Tinuum Group. As of September 30, 2019,2020, Tinuum Group has 2321 invested RC facilities of which 119 are leased to a single customer. A majority of these leases are periodically renewed andrenewed. Further, the ability to generate Section 45 tax credits related to Tinuum's RC facilities expires in 2021. The loss of thisa single customer by Tinuum Group or material modification to the lease termsexpiration of these facilities by this customerSection 45 tax credits would have a significant adverse impact on Tinuum Group's financial position, results of operations and cash flows, which in turn would have a material adverse impact on the Company’s financial position, results of operations and cash flows.

The Company's revenues, sales volumes, earnings and cash flows are significantly affected by prices of competing power generation sources such as natural gas and renewable energy. Low natural gas prices make it a competitive alternative to coal-fired power generation and therefore, coal consumption may be reduced, which reduces the demand for our products. In addition, coal consumption and demand for our products is also affected by the demand for electricity, which is higher in the warmer and colder months of the year. Abnormal temperatures during the summer and winter months may significantly reduce coal consumption and thus the demand for the Company's products.

New Accounting Standards
Recently Adopted
In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842) ("ASU 2016-02"), which created ASC Topic 842 - Leases ("ASC 842"), requiring lessees to recognize a right of use asset and related lease liability for those leases classified as operating leases at the commencement date and have lease terms of more than 12 months. ASC 842 retains the distinction between finance leases (formerly defined as capital leases) and operating leases. On January 1, 2019, the Company adopted ASC 842 retrospectively beginning with the date of adoption. Under this adoption method, the application date is the beginning of the reporting period in which the Company first applies the provisions of ASC 842. Accordingly, the Company’s reporting for the comparative periods presented in the financial statements and related disclosures continues in accordance with legacy U.S. GAAP under ASC Topic 840 - Leases ("ASC 840"). The adoption of ASC 842 had no impact to the opening balance of Retained earnings.
As of the adoption date, the Company recorded $7.0 million and $7.0 million of "right of use" ("ROU") assets and incremental lease liabilities, respectively. The cumulative effect of the change from the adoption of ASC 842 to the Consolidated Balance Sheet as of January 1, 2019 is shown in the table that follows:
  Balance as of Impact of Balance as of

Other long-term liabilities $940
 $3,871
 $4,811
See Note 6 for additional disclosures required under ASC 842 in the year of adoption.
As of January 1, 2019, Tinuum Group adopted ASU 2016-02 and ASU 2014-09 (Topic 606), Revenue from Contracts with Customers and related pronouncements ("ASC 606"). As a result of Tinuum Group’s adoption of these pronouncements, the Company recorded a cumulative effect increase of $28.8 million to Retained earnings as of January 1, 2019, based on the Company's ownership percentage of Tinuum Group's cumulative effect adjustment, and increased its investment balance in Tinuum Group in the amount of $37.2 million and established a deferred tax liability of $8.4 million. As a result of the increase in the investment balance in Tinuum Group, for the nine months ended September 30, 2019, the Company recognized equity earnings in Tinuum Group based on its pro-rata share of Tinuum Group’s net income rather than based on cash distributions received as had been required in prior periods as a result of the cumulative cash distributions exceeding the cumulative pro-rata share of Tinuum Group's net income.
Not Yet Adopted
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"). The main objective of ASU 2016-13 is to provide financial statement users with more decision-useful information about the expected credit losses on financial instruments and other commitments to extend credit held by a reporting entity at each reporting date. To achieve this objective, the amendments in ASU 2016-13 replace the incurred loss impairment methodology in current U.S. GAAP with a methodology that reflects expected credit losses and requires consideration of a broader range of reasonable and supportable information to inform credit loss estimates. ASU 2016-13 is effective for "smaller reporting companies" (as defined by the Securities and Exchange Commission) for fiscal years beginning after December 15, 2019,2022, including interim periods within those years, and must be adopted under a modified retrospective method approach. Entities may adopt ASU 2016-13 earlier as of the fiscal years beginning after December 15, 2018, including interim periods within those years. The Company is currently evaluating the provisions of this guidance and assessing its impact on the Company's financial statements and disclosures. The Companydisclosures and does not believe this standard will have a material impact on the Company's financial statements and disclosures.

The amendments in ASU 2018-132019-12 simplify various aspects related to accounting for income taxes by removing certain exceptions contained in Topic 740 and also clarify and amends existing guidance in Topic 740 to improve consistent application. ASU 2019-12 is effective for public business entities beginning after December 15, 2020, including interim periods within those years, and early adoption is permitted.

Note 2 - Customer Supply Agreement
On September 30, 2020, the Company and Cabot Norit Americas, Inc., ("Cabot") entered into a supply agreement (the "Supply Agreement") pursuant to which the Company agrees to sell and deliver to Cabot, and Cabot agrees to purchase and accept from the Company certain lignite-based AC products ("Furnace Products"). The term of the Supply Agreement is for 15 years with 10-year renewal terms that are automatic unless either party provides three years prior notice of intention not to renew before the end of any term.
In addition to the sale by the Company and purchase by Cabot of Furnace Products, the Company and Cabot have agreed to additional terms whereby Cabot will reimburse the Company for certain capital expenditures incurred by the Company that are necessary to manufacture the Furnace Products. Reimbursements will be in the form of revenues earned from capital expenditures incurred that will benefit both the Company and Cabot (referred to as "Shared Capital") and capital expenditures incurred that will benefit Cabot exclusively (referred to as "Specific Capital"). Both the Company and Cabot must mutually agree with all Shared Capital and Specific Capital expenditures that are necessary to support operational needs in advance of procurement and commissioning.
Revenues will be earned on fair value measurements in Topic 820, Fair Value MeasurementShared Capital ("Topic 820"Shared Capital revenues"), based on the conceptspercentage of Furnace Products produced and sold divided by the Company’s total products produced and sold multiplied by a mutually agreed to factor, which is based on the cost of Shared Capital assets placed in FASB Concepts Statement, Conceptual Frameworkservice amortized as an annuity over the expected asset life (lives) with interest at a rate that was mutually agreed to by both the Company and Cabot. Shared Capital revenues are recognized and billable beginning on the first day of a half year (either January 1 or July 1 of a calendar year) following the placed in service date of a Shared Capital asset(s).
Revenues will be earned on Specific Capital ("Specific Capital revenues") and are based on a mutually agreed to factor, which is based on the cost of Specific Capital assets placed in service amortized as an annuity over five years with interest at a rate

that was mutually agreed to by both the Company and Cabot. Specific Capital revenues are recognized beginning on the first day of a half year (either January 1 or July 1 of a calendar year) following the placed in service date of a Specific Capital asset(s) and are billable in quarterly installments beginning on the first day of a half year following the placed in service date of a Specific Capital asset(s). In the event that Cabot ceases to make purchases under the Supply Agreement, Cabot is obligated to pay the balance of any outstanding payments for Specific Capital.
Note 3 - Acquisition of Marshall Mine
Concurrently with the execution of the Supply Agreement, on September 30, 2020, the Company entered into an agreement to purchase (the "Purchase Agreement") from Cabot 100% of the membership interests in Marshall Mine, LLC (the "Marshall Mine Acquisition") for Financial Reporting - Chapter 8: Notesa nominal purchase price. Marshall Mine, LLC owns a lignite mine located outside of Marshall, Texas (the "Marshall Mine"). The Company independently determined to Financial Statements, includingimmediately commence activities to shutter the considerationMarshall Mine and will incur the associated reclamation costs.
In conjunction with the execution of the Supply Agreement and the Purchase Agreement, on September 30, 2020, the Company entered into a reclamation contract (the "Reclamation Contract") with a third party that provides a capped cost, subject to certain contingencies, in the amount of approximately $19.7 million plus an obligation to pay certain direct costs and benefits. ASU 2018-13of approximately $3.6 million (collectively, the "Reclamation Costs") over the estimated reclamation period of 10 years (the "Reclamation Period"). Under the terms of the Supply Agreement, Cabot is effectiveobligated to reimburse the Company for fiscal$10.2 million of Reclamation Costs (the "Reclamation Reimbursements"), which are payable semi-annually over 13 years and interim periods within those fiscal years, beginning after December 15, 2019. inclusive of interest. In the event that Cabot has a change in control as described in the Supply Agreement, all outstanding balances of the Reclamation Reimbursements shall be due and payable in full. See further discussion of the Reclamation Costs and Reclamation Reimbursements in Note 4.
The amendments on changes in unrealized gains and losses,Marshall Mine Acquisition included the range and weighted-averageacquisition of significant unobservable inputs used to develop Level 3 fair value measurements,certain assets that will be consumed and the narrative descriptionassumption of measurement uncertaintycertain liabilities that will be paid in reclamation of the Marshall Mine in addition to the incurrence of an obligation for the Reclamation Costs. The Company determined that the Marshall Mine Acquisition should be applied prospectively for onlytreated as an asset acquisition as it did not meet the most recent interim or annual period presented indefinition of a business. That is, the initial fiscal year of adoption. All other amendments should be applied retrospectively to all periods presented upon their effective date. Early adoption is permitted upon issuance of this update. An entity is permitted to early adopt any removed or modified disclosures upon issuance of this update and delay adoption ofCompany concluded that the additional disclosures until their effective date. The Company is currently evaluating the provisions of ASU 2018-13 and assessing its impact on the Company's financial statement disclosures. The CompanyMarshall Mine does not believe this standard will have a material impact onany economic reserves, as the Company's financial statement disclosures.
Note 2 - AcquisitionCompany has commenced full reclamation as of September 30, 2020, and therefore lacks inputs.
As described in Note 1, on the Marshall Mine Acquisition Date,represents a transaction with a customer of net assets acquired and liabilities assumed from Cabot, the Company completedhas accounted for the Carbon Solutions Acquisition for a total purchase priceexcess of $75.0 million (the "Purchase Price"). The results of Carbon Solutions have been included in the Company’s consolidated financial statements since the Acquisition Date. The fair value of liabilities assumed over assets acquired as upfront consideration transferred to a customer, Cabot (the "Upfront Customer Consideration"). The amount of the purchase consideration totaled $66.5 million and consistedUpfront Customer Consideration is also recognized net of an additional asset recognized in the Marshall Mine Acquisition, which is comprised of a receivable from Cabot (the "Cabot Receivable") for the Reclamation Reimbursements.

The Company also evaluated the Marshall Mine entity as a potential variable interest entity ("VIE"), and determined that because of its structure and closing-stage status, it does not have sufficient equity at-risk and would not likely be able to obtain additional subordinated financial support to complete its closing stage obligations. The Company purchased all of the membership interests in Marshall Mine, LLC and has determined that the Company is the primary beneficiary. Therefore, Marshall Mine, LLC has been determined to be a VIE and Marshall Mine, LLC’s assets and liabilities have been consolidated as of September 30, 2020.
Adjustments
Note 4 - Marshall Mine Asset Retirement Obligation and related Cabot Receivable
Asset Retirement Obligation
In connection with the Supply Agreement, Purchase Agreement and the Reclamation Contract, the Company assumed the obligation to reclaim and restore the land associated with the Marshall Mine. The Company determined that the Marshall Mine does not have any remaining economic reserves. As of September 30, 2020, the Company recorded an asset retirement obligation (the "Marshall Mine ARO") for the total Reclamation Costs of $21.3 million as measured at the expected future cash flows of $23.7 million, inclusive of contingency costs, discounted to their present value using a discount rate based on a credit-adjusted, risk-free rate of 7.0%.
Cabot Receivable
As previously disclosed, under the terms of the related Supply Agreement, Cabot is obligated to pay Reclamation Reimbursements to the preliminary purchase price allocation primarily relate to changes in fair values assigned to property, plant and equipment, intangible assets, mine reclamation liability and the related mine reclamation asset as a resultCompany for $10.2 million of the finalReclamation Costs, inclusive of interest. As of September 30, 2020, the Company recorded the Cabot Receivable for the Reclamation Reimbursements at its estimated fair value, which is measured using a discounted cash flows valuation report frommodel that considers the Company's third-party valuation firm issued in May 2019. Duringestimated credit risk associated with the three months ended Juneobligor’s (Cabot’s) future performance. Interest will be accreted on a monthly basis and recognized as interest income. There were no significant related fees or costs associated with the Cabot Receivable.
As of September 30, 2019 based on new information2020, the Company recorded the Cabot Receivable at its estimated fair value of facts$9.7 million, reflecting a discount rate of approximately 1.5% or $0.5 million. Allowances for this asset are assessed periodically, and circumstances that existed0 allowance was deemed necessary as of September 30, 2020.
Surety Bond
As the Acquisition Date,owner of the Marshall Mine, the Company revisedis required to post a surety bond to ensure performance of its estimates usedreclamation activities. On September 30, 2020, the Company and a third party entered into a surety bond indemnification agreement (the "Surety Agreement") pursuant to which the Company secured and posted a $30.0 million surety bond (the "Bond") with the local regulatory agency. The Bond will remain in place until the Marshall Mine is fully reclaimed, and it may be reduced in amount from time to time as the Company progresses with its reclamation activities. For the obligations due under the Reclamation Contract, the Company was required to post collateral of $5.0 million dollars as of September 30, 2020 and an additional $5.0 million dollars as of March 31, 2021.
Note 5 - Impairment
As part of its periodic review of the Acquisition Date relatedcarrying value of long-lived assets, the Company assessed its long-lived assets for potential impairment. In assessing impairment of its PGI segment's and certain other long-lived asset groups, the Company considered factors such as the significant decline in both the PGI segment's trailing twelve months revenues and current and future years’ forecasted revenues. These factors are largely due to the net realizable valuesignificant drop in coal-fired power dispatch that began in 2019 amid historically low prices of certain finished goods inventory itemsalternative power generation sources such as natural gas leading to an increase in natural gas usage as well as values assigned toother competing energy sources.
As of June 30, 2020, the Company completed an undiscounted cash flow analysis of its PGI segment's and certain prepaidother long-lived assets (the "Asset Group"), which are comprised of its manufacturing plant and accrued expense items.
The adjustments were recordedrelated assets and its lignite mine assets, and estimated the undiscounted cash flows from the Asset Group at $54.7 million, which was less than the carrying value of the Asset Group of $58.3 million. Accordingly, the Company completed an assessment of the Asset Group’s fair value and estimated the fair value of the Asset Group at $32.2 million. This resulted in an impairment and write-down of the Asset Group (the "Impairment Charge") of $26.1 million as of June 30, 2019 and were included2020, which is reflected as "Impairment of long-lived assets" in the Condensed Consolidated Balance Sheet as of that date and the resultant impact to the StatementStatements of Operations was reflected for the three months ended June 30, 2019.

Unaudited Pro Forma Financial Information
The following represents the pro forma effects of the Carbon Solutions Acquisition as if it had occurred on January 1, 2017. The pro forma pre-tax income for the period presented has been calculated after applying the Company’s accounting policies in effect for 2017 and 2018. In addition, pro forma net income for the three and nine months ended September 30, 2018 includes: (1)2020. The Impairment Charge was allocated to the impact on Carbon SolutionsPGI segment and Other in the amounts of the adoption of ASC 606 effective January 1, 2018, which resulted in a reclassification of $2.1$23.2 million and $5.9$2.9 million, respectively, from Revenues to Cost of Revenue for freight costs billed to customers, with no impact to income from operations; (2) the reduction in depletion, depreciation and amortization resulting from the purchase price adjustments to Property, plant and equipment and Mine development costs; (3) the adjustment to interest expense from the combination of the Senior Term Loan that was used to fund the Carbon Solutions Acquisition and the elimination of certain debt of Carbon Solutions as a result of pay-offs by the Company as of the Acquisition Date; and (4) the removal of $1.0 million and $4.2 million in transaction costs incurred for the three and nine months ended September 30, 2018, respectively, together with the income tax effect on (1) through (4). The pro forma results do not include any anticipated synergies or other expected benefits of the Carbon Solutions Acquisition.

The following table summarizes the allocation to the Asset Group of the Impairment Charge of $26.1 million recorded as of June 30, 2020:
(in thousands)
Property, plant and equipment, net$18,986 
Intangible assets, net1,445 
Other long-term assets, net5,672 
Total impairment$26,103 
The Company engaged an independent third party to perform the valuation of the Asset Group in order to determine the estimated fair value of the Asset Group. This valuation was based on the use of several established valuation models including an expected future discounted cash flow model using Level 3 inputs under ASC 820 - Fair Value Measurement. The cash flows are those expected to be generated by market participants discounted at the risk-free rate of interest. Because of the continued future uncertainty surrounding the level of coal-fired dispatch, the impact of historically low natural gas prices and other estimates impacting the expected future cash flow, it is reasonably possible that the expected future cash flows may change in the near term and may result in the Company recording additional impairment of the Asset Group.
As of September 30, 2020, the Company determined that there was 0 additional impairment of the Asset Group.
Note 6 - COVID-19
In response to the COVID-19 outbreak, in March 2020, the federal government passed the Coronavirus Aid, Relief, and Economic Security Act (the "CARES Act"). The CARES Act provided, among other things, the creation of the Paycheck Protection Program ("PPP"), which is sponsored and administered by the U.S. Small Business Administration ("SBA").
On April 20, 2020, the Company entered into a loan (the "PPP Loan") under the PPP, evidenced by a promissory note, with BOK, NA dba Bank of Oklahoma ("BOK") providing for $3.3 million in proceeds, which was funded to the Company on April 21, 2020. The PPP Loan matures April 21, 2022 and provides for 18 monthly payments of principal and interest commencing on November 21, 2020. The interest rate on the PPP Loan is 1.00%. The PPP Loan is unsecured and contains customary events of default relating to, among other things, payment defaults, making materially false and misleading representations to the SBA or BOK, or breaching the terms of the PPP Loan. The occurrence of an event of default may result in the repayment of all amounts outstanding, collection of all amounts owing from the Company, or filing suit and obtaining judgment against the Company. The PPP Loan principal may be forgiven subject to the terms of the PPP and approval by the SBA.
The Company recorded the PPP Loan as a debt obligation under the guidance of ASC 470 - Debt and will accrue interest over the 18-month term of the PPP Loan beginning November 21, 2020.
The CARES Act also provided the deferral of payroll tax payments for all payroll taxes incurred through December 31, 2020. The Company elected to defer payments of payroll taxes for the periods allowed under the CARES Act and will repay 50% by December 31, 2021 and 50% by December 31, 2022. As of September 30, 2020, the Company has deferred $0.3 million of payroll tax payments under the CARES Act.
Note 47 - Equity Method Investments
Tinuum Group, LLC
The Company's ownership interest in Tinuum Group was 42.5% as of September 30, 20192020 and December 31, 2018.2019. Tinuum Group supplies technology equipment and technical services at select coal-fired generators, but its primary purpose is to put into operation facilities that produce and sell refined coal ("RC")RC that lower emissions and also qualify for Section 45 tax credits. Tinuum Group has been determined to be a variable interest entity ("VIE");VIE; however, the Company does not have the power to direct the activities that most significantly impact Tinuum Group's economic performance and has therefore accounted for the investment under the equity method of accounting. The Company determined that the voting partners of Tinuum Group have identical voting rights, equity control interests and board control interests, and therefore, concluded that the power to direct the activities that most significantly impact Tinuum Group's economic performance was shared.

Note 611 - Leases
The financial statement impact from the adoption of ASC 842 as of January 1, 2019 is due to recording ROU assets and related lease liabilities for operating lease commitments that were outstanding as of December 31, 2018. The Company has elected the transitional practical expedients allowed under ASC 842, which include among other things that the Company need not reassess: (1) whether any existing contracts are or contain leases, inclusive of land easements; (2) the lease classification or lease term for existing leases; and (3) initial direct costs for any existing leases. In addition, the Company has elected for all classes of underlying assets the practical expedient to not separate nonlease components from lease components and to account for each separate lease component and the nonlease components associated with that lease component as a single lease component.
ASC 842 defines a lease as a contract, or part of a contract, that conveys the right to control the use of an identified asset for a period of time in exchange for consideration. Control over the use of an identified asset means that an entity has both the right to obtain substantially all of the economic benefits from the use of an identified asset and the right to direct the use of that identified asset. The determination of whether a contract contains a lease may require significant assumptions and judgments.
Historically, Carbon Solutions has used leasing to fund the majority of its capital needs for mining and manufacturing equipment. As of September 30, 2019,2020, the Company has obligations under finance and operating leases in the amounts of $7.1$5.8 million and $5.9$3.5 million, respectively. ROU assets under finance leases are mining equipment used at the Company’s lignite mine, which provides the key raw materials for manufacturing the Company’s products. ROU assets under operating leases are primarily plant equipment used at the Company’s manufacturing facility, but also include other office equipment, vehicles and office facilities. As of September 30, 2019,2020, the Company has ROUright of use ("ROU") assets, net of accumulated amortization, under finance leases and operating leases of $6.4$2.6 million and $5.9$2.3 million, respectively.
Certain of the finance and operating leases have options permitting renewals for additional periods and buy-out options. Renewal and buy-out options for applicable leases have not been included in the measurement of the respective lease liabilities as the Company is not reasonably certain that it will exercise the respective option or the lessor does not have an exclusive right to exercise the option.
Variable lease payments represent payments made by a lessee for the right to use an underlying asset that vary because of changes in facts or circumstances occurring after the commencement date of a lease other than the passage of time. Variable lease payments that are based on an index or rate, calculated by using the index or rate that exists on the lease commencement date, are included in the measurement of a lease liability. Certain of the Company’s operating leases for office facilities contain variable lease components that are not based on an index or rate, and the Company recognizes these payments as lease expense in the period in which the obligation for those payments is incurred.
The Company calculates lease liabilities based on the present value of lease payments discounted by the rate implicit in the lease or, if not readily determinable, the Company’s incremental borrowing rate.
The Company records lease liabilities and related ROU assets for all leases that have a term of greater than one year. For short-term leases (leases with terms of less than one year), the Company expenses lease payments on a straight-line basis over the lease term.
Finance leases
Leases classified as capital leases under ASC 840 and the related assets and liabilities were recorded and classified as finance leases as of January 1, 2019 based on their carrying values of $8.1 million and $8.2 million, respectively, as of December 31, 2018. ROU assets under finance leases and finance lease liabilities are included in Property, plant and equipment and Current portion and Long-term portion of borrowings, respectively, in the Condensed Consolidated Balance SheetSheets as of September 30, 2019.
Finance lease liabilities are subsequently measured by increasing the carrying amount to reflect interest expense on the finance lease liability2020. and reducing the carrying amount of the lease liability to reflect lease payments made during the period. Interest on finance lease liabilities is determined in each period during the lease term as the amount that produces a constant periodic discount rate on the remaining balance of the lease liability. ROU assets under finance leases are amortized over the remaining lease term on a straight-line basis.December 31, 2019. Interest expense related to finance lease liabilities and amortization of ROU assets under finance leases are included in Interest expense and Depreciation, amortization, depletion and accretion, respectively, in the Condensed Consolidated Statement of Operations for the three and nine months ended September 30, 2019.

September 30, 2019.
Operating leases
Operating lease liabilities as of January 1, 2019 were calculated at the present value, using a discount rate of the lease, of the remaining minimum rental payments (as defined under ASC 840). As the rate implicit in all of the operating leases was not readily determinable, the Company determined its discount rate as of January 1, 2019 based on an estimate of its incremental borrowing rate. This rate was based on the Company’s effective borrowing rate on the Senior Term Loan, considering the collateral requirements contained therein, in effect as of January 1, 2019. ROU assets under operating leases as of January 1, 2019 were determined as the calculated value of the operating lease liabilities less accrued lease payments and accrued lease incentives. As of December 31, 2018, the total amount of accrued lease payments and accrued lease incentives was approximately $0.1 million. ROU assets under operating leases and operating lease liabilities are included in Other long-term assets and Other liabilities and Other long-term liabilities, respectively, in the Condensed Consolidated Balance Sheet as of September 30, 2020 and December 31, 2019.
Operating lease liabilities are subsequently measured at the present value of the lease payments not yet paid discounted using the discount rate for the lease established at the inception date of the lease (or January 1, 2019Lease expense for operating leases in effect asfor the three and nine months ended September 30, 2020 was $1.1 million and $3.5 million, respectively, of December 31, 2018). ROU assets under operating leases are subsequently measured at the amounts of the related operating lease liability, adjusted for, as applicable, prepaid or accrued lease payments, the remaining balance of any lease incentives received, unamortized initial direct costswhich $1.0 million and impairment. Lease expense from operating leases$2.9 million, respectively, is recognized as a single lease cost over the remaining lease term on a straight-line basis. Variable lease payments not included in operating lease liabilities are recognized as expenseConsumables - cost of revenue, exclusive of depreciation and amortization, and $0.1 million and $0.6 million, respectively, is included in General and administrative in the period in which the obligation for those payments is incurred.Condensed Consolidated Statement of Operations. Lease expense for operating leases for the three and nine months ended September 30, 2019 was $1.1 million and $3.3 million, respectively, of which $1.0 million and $3.1 million, respectively, is included in Consumables - cost of revenue, exclusive of depreciation and amortization, and $0.1 million and $0.3 million, respectively, is included in General and administrative in the Condensed Consolidated Statement of Operations for the three and nine months ended September 30, 2019.Operations.
In August 2019, the Company entered into a new lease agreement covering approximately twenty-one thousand square feet of office space for a term of 3.5 years and recorded a ROU asset of $1.2 million and a corresponding operating lease liability of $1.2 million.

The effective tax rate for the three and nine months ended September 30, 20192020 was different from the federal statutory rate due to increases of $4.8 million and $3.6 million, respectively,primarily from changes in the valuation allowance on deferred tax assets. These charges wereassets, most notably an increase of $5.1 million for the nine months ended September 30, 2020. The increase in the valuation allowance was a result of a reduction in forecasts as of September 30, 2020 from forecasts as of December 31, 2019 of current and future years' taxable income. In addition, the effective rate for both the three and nine months ended September 30, 2019 was increased by state income tax expense, net of federal benefit.
The Company assesses the valuation allowance recorded against deferred tax assets at each reporting date. The determination of whether a valuation allowance for deferred tax assets is appropriate requires the evaluation of positive and negative evidence that can be objectively verified. Consideration must be given to all sources of taxable income available to realize the deferred tax asset,assets, including, as applicable, the future reversal of existing temporary differences, future taxable income forecasts exclusive of the reversal of temporary differences and carryforwards, taxable income in carryback years and tax planning strategies.

Note 1318 - Business Segment Information
Operating segments are defined as components of an enterprise about which separate financial information is available that is evaluated regularly by a company's chief operating decision maker ("CODM"), or a decision-making group, in deciding how to allocate resources and in assessing financial performance. As of September 30, 2019,2020, the Company's CODM was the Company's CEO. The Company's operating and reportable segments are identified by products and services provided.
As of September 30, 2019,2020, the Company has two2 reportable segments: (1) Refined Coal ("RC"); and (2) Power Generation and Industrials ("PGI").
The business segment measurements provided to and evaluated by the CODM are computed in accordance with the principles listed below:
The accounting policies of the operating segments are the same as those described in the summary of significant accounting policies in the 20182019 Form 10-K.
Segment revenues include equity method earnings and losses from the Company's equity method investments.
Segment operating income (loss) includes segment revenues and allocation of certain "Corporate general and administrative expenses," which include Payroll and benefits, Legal and professional fees and General and administrative.
RC segment operating income includes interest expense directly attributable to the RC segment.
As of September 30, 20192020 and December 31, 2018,2019, substantially all of the Company's material assets are located in the U.S. and substantially all of significant customers are U.S. companies. The following table presents the Company's operating segment results for the three and nine months ended September 30, 20192020 and 2018:2019:

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations
The following discussion and analysis of our financial condition and results of our operations should be read together with the unaudited Condensed Consolidated Financial Statements and notes of Advanced Emissions Solutions, Inc. ("ADES" or the "Company") included elsewhere in Item 1 of Part I of this Quarterly Report and with the audited consolidated financial statements and the related notes of ADES included in the 20182019 Form 10-K.
Overview
We provideare a leader in consumable air and water treatment options that utilize activated carbon ("AC") and chemical based technologies. Our proprietary environmental solutions to customerstechnologies sold in the power generation and industrial ("PGI") market, which includes coal-fired power generation, municipal waterplants and other industries primarily through emissionsindustrial, and water purification control technologies oftreatment market, enable our subsidiaries and joint ventures. Our proprietary technologies and associated product offerings provide pollutant control solutions to enable coal-fired power generators, industrials and municipal watercustomers to reduce emissions of mercury and other air pollutants, maximize utilization levels and improve operating efficiencies to assistmeet the challenges of existing and potential emissions control regulations.
Through our wholly-owned subsidiary, ADA Carbon Solutions, LLC ("Carbon Solutions"), which we acquired on December 7, 2018 (the "Acquisition Date"), we manufacture and sell activated carbon ("AC") used in contaminant capture and removal for coal-fired power plants and industrial and water treatment markets. Carbon Solutions also owns an associated lignite mine that supplies the purification of water.primary raw material for manufacturing our products.
We operate two segments: Refined Coal ("RC") and Power Generation and Industrials ("PGI") (f/k/a "Emissions Control" or "EC"). Our RC segment is comprised of our equity ownership in Tinuum Group, LLC ("Tinuum Group") and Tinuum Services, LLC ("Tinuum Services"), anboth of which are unconsolidated entity thatentities in which we generate substantial earnings. Tinuum Group provides reduction of mercury and nitrogen oxide ("NOX")emissions at select coal-fired power generators through the production and sale of RC that qualifies for tax credits ("Section 45 tax credits") under the Internal Revenue Code Section 45 - Production Tax Credit ("IRC Section 45 tax credits"45"). We benefit from Tinuum Group's production and sale of RC, which generates tax credits, as well as its revenue from selling or leasing RC facilities to tax equity investors. We also earn royalties for technologies that we license to Tinuum Group and used at certain RC facilities to enhance combustion and reduced emissions of NOx and mercury from coal burned to generate electrical power. Tinuum Services operates and maintains the RC facilities under operating and maintenance agreements with Tinuum Group and owners or lessees of the RC facilities.
Our PGI segment includes the sale of products that provideremove mercury control and other air and water contaminants control tofrom coal-fired power generators and other industrial companies. Our primary products are comprised of AC which is produced from lignite coal, which creates activated carbon ("AC"). Fromcoal. Our AC we manufacture various forms of AC thatproducts include powdered activated carbon ("PAC") and granular activated carbon ("GAC"). There are three primary consumable products that work in conjunction with the installed equipment at coal-fired utilities to control mercury: PAC, coal additives and scrubber additives. In many cases, these three consumable products can be used together or, in many circumstances, substituted for each other. However, activated carbonPAC is typically the most efficient and effective way to capture mercury and currently accounts for over 50% of the mercury control consumables North American market.
Drivers of Demand and Key Factors Affecting Profitability
Drivers of demand and key factors affecting our profitability differ by segment. In the RC segment, demand is driven primarily by IRC Section 45, which is expected to expire no later than December 31, 2021. Operating results in RC have been influenced by: (1) the ability to sell, lease or operate RC facilities; (2) lease renegotiation or termination; and (3) changes in tonnage of RC due to changing coal-fired dispatch and electricity power generation sources. In the PGI segment, demand is driven primarily by consumables-based solutions for coal-fired power generation and other industrials. Operating results in PGI have been influenced by: (1) changes in our sales volumes; (2) changes in price and product mix; and (3) changes in coal-fired dispatch and electricity power generation sources.
Customer Supply Agreement
On December 7, 2018September 30, 2020, we and Cabot Norit Americas, Inc., ("Cabot") entered into a supply agreement (the "Acquisition Date""Supply Agreement"), pursuant to which we acquiredagree to sell and deliver to Cabot, and Cabot agrees to purchase and accept from us, certain lignite-based activated carbon products ("Furnace Products"). The term of the Supply Agreement is for 15 years with 10-year renewal terms that are automatic unless either party provides three years prior notice of intention not to renew before the end of any term.
In addition to the sale by us and purchase by Cabot of Furnace Products, we and Cabot have agreed to additional terms whereby Cabot will reimburse us for certain capital expenditures incurred by us that are necessary to manufacture the Furnace Products. Reimbursements will be in the form of revenues earned from capital expenditures incurred that will benefit both us and Cabot (referred to as "Shared Capital") and capital expenditures incurred that will benefit Cabot exclusively (referred to as "Specific
29


Capital"). Both we and Cabot must mutually agree with all Shared Capital and Specific Capital that are necessary to support operational needs in advance of procurement and commissioning.
We believe the Supply Agreement will provide material incremental volume and capture lower operating cost efficiencies of our manufacturing plant. As these incremental volumes come on-line and after our existing inventory balances are sold, we anticipate an increase in gross margins. Further, the Supply Agreement will expand our activated carbon products to diverse end markets that are outside of coal-fired power generation.
Acquisition of Marshall Mine
Concurrently with the execution of the Supply Agreement, on September 30, 2020, we entered into an agreement to purchase (the "Carbon Solutions Acquisition""Purchase Agreement") from Cabot 100% of the equitymembership interests in Marshall Mine, LLC (the "Marshall Mine Acquisition") for a nominal purchase price. Marshall Mine, LLC owns a lignite mine located outside of ADA Carbon Solutions, LLC (“Carbon Solutions”Marshall, Texas (the "Marshall Mine"). Carbon SolutionsWe independently determined to immediately commence activities to shutter the Marshall Mine and will incur the associated reclamation costs.
In conjunction with the execution of the Supply Agreement and the Purchase Agreement, on September 30, 2020, we entered into a reclamation contract (the "Reclamation Contract") with a third party that provides a capped cost, subject to certain contingencies, in the amount of approximately $19.7 million plus an obligation to pay certain direct costs of approximately $3.6 million (collectively, the "Reclamation Costs") over the estimated reclamation period of 10 years. Under the terms of the Supply Agreement, Cabot is a manufacturerobligated to reimburse us for $10.2 million of Reclamation Costs (the "Reclamation Reimbursements"), which are payable semi-annually over 13 years and sellerinclusive of ACinterest.
As of September 30, 2020, we recorded an asset retirement obligation related to the Reclamation Contract in the amount of $21.3 million and a leaderreceivable related to the Reclamation Reimbursements in mercury capture using PACthe amount of $9.7 million, net.
Impairment
As part of our periodic review of the carrying value of long-lived assets, we assessed our long-lived assets for potential impairment. In assessing impairment of our PGI segment's and certain other long-lived asset groups, we considered factors such as the significant decline in both the PGI segment's trailing twelve months revenues and current and future years’ forecasted revenues. These factors are largely due to the significant drop in coal-fired power dispatch that began in 2019 amid historically low prices of alternative power generation sources, such as natural gas, leading to an increase in natural gas usage as well as other competing energy sources. Natural gas prices continue to be highly volatile, which may impact our volumes and corresponding revenues that could result in future impairment.
As of September 30, 2020, we concluded that there was no impairment of our long-lived assets. However, as of June 30, 2020, we completed an undiscounted cash flow analysis of our PGI segment's and certain other long-lived asset group (the "Asset Group"), which is comprised of our manufacturing plant and related assets and our lignite mine assets, and estimated the undiscounted cash flows from the Asset Group, which were less than the carrying value of the Asset Group. The decrease in undiscounted cash flows was due to lower volumes impacted by overall lower power generation and an increase in power generation from sources other than coal as a percentage of total generation. Accordingly, we completed an assessment of the Asset Group’s fair value and estimated the fair value of the Asset Group at $32.2 million. This resulted in an impairment and write-down of the Asset Group of $26.1 million as of June 30, 2020, and which is reflected as "Impairment of long-lived assets" in the Condensed Consolidated Statements of Operations for the coal-fired power plant, industrialnine months ended September 30, 2020. The total impairment charge was allocated to the PGI segment and water treatment markets. Carbon Solutions also owns an associated lignite mine that suppliesOther in the primary raw materialamounts of $23.2 million and $2.9 million, respectively, for manufacturing powdered activated carbon. Carbon Solutions was formed in 2008the nine months ended September 30, 2020.
Impact of COVID-19
In March 2020, the World Health Organization ("WHO") declared the novel strain of coronavirus ("COVID-19") a global pandemic. We are designated by the Cybersecurity and Infrastructure Security Agency ("CISA") of the Department of Homeland Security as a 50/50 joint venture bycritical infrastructure supplier to the Companyenergy sector. Our operations have been deemed essential and, Energy Capital Partners LLC.therefore, our facilities remain open and our employees employed. We follow the COVID-19 guidelines from the Centers for Disease Control concerning the health and safety of our personnel, including remote working for those that have the ability to do so, sequestered employees at our plant and other heath safety measures. These measures have resulted in an increase in our personnel costs, operational inefficiencies and the incurrence of incremental costs to allow manufacturing operations to continue; while at the same time we have faced a general downturn in our sales and marketing efforts. The duration of these measures is unknown, may be extended and additional measures may be imposed.
Both of our business segments have continued to operate during the pandemic, and we have taken certain proactive and precautionary steps to ensure the safety of our employees, customers and suppliers, including frequent cleaning and disinfection of workspaces, property, plant and equipment, instituting social distancing measures and mandating remote working
30


environments, where possible, for all employees. We cannot, however, predict the long-term effects on our business, including our financial position or results of operations, if governmental restrictions or other such directives continue for a prolonged period of time and cause a material negative change in power generation demand, materially disrupt our supply chain, substantially increase our operating costs or limit our ability to serve existing customers and seek new customers.
In response to the COVID-19 outbreak, in March 2020, the federal government passed the Coronavirus Aid, Relief, and Economic Security Act (the "CARES Act"). The CARES Act provided, among other things, the deferral of payroll tax payments for all payroll taxes incurred through December 31, 2020. The Company relinquished its ownership in 2011 as parthas elected to defer payments of a legal settlement agreement as described in the Company's Annual Report on Form 10-Kpayroll taxes for the fiscal year endedperiods allowed under the CARES Act and will repay 50% by December 31, 2017. The Company acquired Carbon Solutions primarily2021 and 50% by December 31, 2022. As of September 30, 2020, total payroll tax payments deferred under the CARES Act were $0.3 million.
During the nine months ended September 30, 2020, we incurred costs of $0.4 million related to expandsequestration of certain of our employees at our manufacturing plant in Louisiana. These costs included hazard pay, lodging and meal expenses for 30 days.
Our customers may also be impacted by COVID-19 pandemic as the Company's product offerings withinutilization of energy has changed. We cannot predict the mercury control industrylong-term impact on our customers and other complimentary PAC markets.the subsequent impact on our business.
Results of Operations
For the three and nine months ended September 30, 2019,2020, we recognized net income of $5.0 million and net loss of $20.7 million, respectively, compared to net income of $3.9 million and $26.4 million compared to net income of $5.5 million and $28.5 million, for the three and nine months ended September 30, 2018.

2019, respectively.
The operating results for the three and nine months ended September 30, 20192020 are primarily attributable to a combination of factors, including:
Continued performance in our RC business segment, principally related to equity earnings and royalties from our Tinuum Group and Tinuum Services, LLC ("Tinuum Services") equity investments;license royalties;
Performance in our PGI business segment, principally related to the Carbon Solutions Acquisition;Solutions;
Impairment recorded related to our PGI segment's and certain other long-lived asset groups; and
Impacts related to changes in income tax expense.
The following sections provide additional information regarding these comparative periods. For comparability purposes, the following tables set forth our results of operations for the periods presented in the Condensed Consolidated Financial Statements included in Item 1 of this Quarterly Report. The period-to-period comparison of financial results may not be indicative of financial results to be achieved in future periods.

Consumables and consumables cost of revenue
For the three months ended September 30, 2019,2020, consumables revenues increased from the comparable periodquarter in 20182019 primarily driven by higher volumes impacting revenue by $2.1 million. Negatively impacting revenue quarter over quarter was less favorable price and product mix of approximately $1.0 million combined. Our gross margin, exclusive of depreciation and amortization, decreased for the three months ended September 30, 2020 compared to the corresponding quarter in 2019 primarily due to Carbon Solutions' operations. These operations alsothe lower volumes during the first half of the current year causing higher fixed cost per pound compared to the prior year.

Consumables revenue continues to be affected by electricity demand driven by seasonal weather and related power generation needs, as well as competitor prices related to alternative power generation sources such as natural gas. According to data provided by the U.S. Energy Information Administration ("EIA"), for the three months ended September 30, 2020, power generation from coal-fired power dispatch was down approximately 10% compared to the corresponding quarter in 2019.
License royalties, related party
For the three months ended September 30, 2020 and 2019, there were 14.6 million tons and 14.5 million tons, respectively, of RC produced using M-45TM and M-45-PCTM technologies ("M-45 Technology"), which Tinuum Group licenses from us ("M-45 License"). While tonnage increased slightly period over period, there was a reduction in the total poundsroyalty rate per ton primarily attributable to higher depreciation recognized of approximately $0.2 million on all royalty bearing RC facilities as a result of a reduction in their estimated useful lives as determined by Tinuum Group during the three months ended September 30, 2019. Further reducing the rate per ton was a decrease in net lease payments of approximately $0.4 million as a result of Tinuum Group restructuring RC facility contracted leases with its largest customer in the second half of 2019. As a result of higher depreciation and lower lease payments, we expect that the lower royalty rate per ton will continue for the remainder of 2020 and in 2021.
Additional information related to revenue concentrations and contributions by class and reportable segment can be found within the Business Segments discussion and in Note 18 to the Condensed Consolidated Financial Statements.

Payroll and benefits
Payroll and benefits expenses, which represent costs related to selling, general and administrative personnel, decreased for the three months ended September 30, 2020 compared to the corresponding quarter in 2019 primarily due to a decrease in headcount and payroll-related expenses.
Legal and professional fees
Legal and professional fees decreased for the three months ended September 30, 2020 compared to the corresponding quarter in 2019 as a result of cost reductions related to professional fees, primarily in consulting and outsourced IT cost specific to the completion of the integration of Carbon Solutions of $1.5 million. The remaining decrease was a result of decreased outsourced shared service costs, including legal fees.
General and administrative
General and administrative expenses decreased for the three months ended September 30, 2020 compared to the corresponding quarter in 2019 primarily due to a reduction in general and administrative expenses including the reduction of travel, as a preventative measure related to the COVID-19 pandemic, and recruiting fees. Offsetting this decrease was an increase in product development expenses of approximately $0.1 million and rent and occupancy expenses of $0.1 million related to property taxes.
Depreciation, amortization, depletion and accretion
Depreciation and amortization expense decreased for the three months ended September 30, 2020 compared to the corresponding quarter in 2019 due to the impairment charge taken in the second quarter of 2020 reducing the value of our fixed assets and intangibles and thus, reducing the corresponding depreciation and amortization expense by approximately $0.6 million. Offsetting this decrease was higher production volumes during the three months ended September 30, 2020, resulting in $0.3 million more absorption of depreciation in inventory. Further, the addition of leasehold improvements at our corporate
32


headquarters in 2020 contributed to approximately $0.1 million of amortization expense for the three months ended September 30, 2020.

Earnings from equity method investments$9,518 $14,426 
Earnings from equity method investments, and changes related thereto, are impacted by our significant equity method investees: Tinuum Group and Tinuum Services.
For the three months ended September 30, 2020 and 2019, we recognized $7.3 million and $11.7 million, respectively, in equity earnings from Tinuum Group, which was equal to our proportionate share of Tinuum Group's net income for the respective quarter.
For the three months ended September 30, 2020, equity earnings from our interest in Tinuum Group were positively impacted by the addition of two new RC facilities during the second half of 2019, a new RC facility added during the three months ended September 30, 2020 and the sale by Tinuum Group of its 49.9% remaining interest in an RC facility during thethree months ended September 30, 2020. However, equity earnings from Tinuum Group for the three months ended September 30, 2020 decreased from the comparable quarter in 2019 primarily from higher depreciation recognized of approximately $0.4 million for the three months ended September 30, 2020 on all Tinuum Group RC facilities as a result of a reduction in RC facilities' estimated useful lives as determined by Tinuum Group during the three months ended September 30, 2019. Further contributing to the decrease in equity earnings quarter over quarter.quarter was the restructuring of RC facility leases with Tinuum Group's largest customer, which decreased lease payments and equity earnings beginning in the second half of 2019. We believe the increase in depreciation and the decrease in lease payments will negatively impact equity earnings for the remainder of 2020 as well as 2021.
Further, two coal-fired utilities in which Tinuum Group has invested RC facilities announced expected closures in the fourth quarter of 2019 and the associated leases of those facilities terminated during that period. As a result of higher depreciation, reduced lease payments and closures of two utilities, we expect our pro-rata share of Tinuum Group’s earnings and distributions to be lower in future periods.
Equity earnings from our interest in Tinuum Services decreased by $0.4 million for the three months ended September 30, 2020 compared to the three months ended September 30, 2019, and for those quarters, Tinuum Services provided operating and maintenance services to 20 and 22 operating RC facilities, respectively. Tinuum Services derives earnings under fixed-fee arrangements as well as fee arrangements that are based on actual RC production, depending upon the specific RC facility operating and maintenance agreement.
33


Interest expense
For the three months ended September 30, 2020, interest expense decreased $0.8 million compared to the three months ended September 30, 2019 primarily due to a reduction in interest expense related to a senior term loan (the "Senior Term Loan"), as the principal balance was reduced from payments of $24.0 million made during the period from September 30, 2019 to September 30, 2020. The remaining decrease in interest expense related to a reduction in the deferred balance during the period from September 30, 2019 to September 30, 2020 related to Internal Revenue Code section 453A ("453A"), which requires taxpayers to pay an interest charge ("453A interest") on the portion of the tax liability that is deferred under the installment method for tax purposes. 
Income tax expense
For the three months ended September 30, 2020, we recorded income tax expense of $0.9 million compared to income tax expense of $6.6 million for the three months ended September 30, 2019. The income tax expense recorded for the three months ended September 30, 2020 was comprised primarily of estimated federal income tax expense of $0.9 million. The income tax expense recorded for the three months ended September 30, 2019 was comprised of estimated federal income tax expense of $6.2 million and estimated state income tax expense of $0.4 million.
The decrease in income tax expense quarter over quarter was primarily due to an increase in the valuation allowance on deferred tax assets for the three months ended September 30, 2019 of $4.8 million. This increase was based on changes in forecasts as of September 30, 2019 compared to forecasts as of June 30, 2019 of future years' taxable income. The decrease in income tax expense quarter over quarter was also attributable to a decrease of $4.7 million in pretax income for the three months ended September 30, 2020 compared to the three months ended September 30, 2019.

Consumables and consumables cost of revenue
For the nine months ended September 30, 2020, consumables revenues decreased from the comparable period in 2019 primarily driven by lower volume of approximately $2.7 million and less favorable price and product mix of approximately $5.0 million combined. Volumes were negatively impacted by lower coal-fired power dispatch driven by a decrease of 4.0% in overall power generation as well as an increase in power generation from sources other than coal as a percentage of total power generation.
Consumables revenue is affected by electricity demand driven by seasonal weather and related power generation needs, as well as competitor prices related to alternative power generation sources such as natural gas. DuringAccording to data provided by the threeEIA, for the nine months ended September 30, 2019, Consumables revenue and margins were negatively impacted by low2020, power generation from coal-fired power dispatch most significantly driven by power generation from sources other than coal. In a recently updated forecast,was down approximately 23% compared to the U.S. Energy Information Administration ("EIA") revised downward by 7% its December 2018 forecastcorresponding period in 2019. However, we anticipate improvements related increased volumes and revenue in the last quarter of 2020 compared to the same period in 2019 due to the Supply Agreement.
Consumables costs of revenue was negatively impacted for 2019 coal-fired electricity-generating units.
License royalties, related party
For the threenine months ended September 30, 2019 and 2018, there were 14.5 million tons and 10.5 million tons, respectively, of RC produced using M-45TM and M-45-PCTM technologies ("M-45 Technology"), which Tinuum Group licenses from us ("M-45 License"). The increase in license royalties was primarily2020 due to Tinuum Group obtaining additional third-party investorssafety actions taken by the Company to provide for new RCcontinued operation of our manufacturing facilities one each during the second and fourth quartersin response to COVID-19.

We anticipate positive impacts to our gross margin starting in 2021 due to the Supply Agreement.
License royalties, related party
For the nine months ended September 30, 2020 and 2019, there were 35.7 million tons and 35.0 million tons, respectively, of RC facilitiesproduced using the M-45 Technology under the M-45 License. While tonnage increased period over period, there was a lowerreduction in the royalty rate per ton rate, which was primarily dueattributable to higher depreciation recognized during the three months ended September 30, 2019of approximately $1.8 million on all royalty bearing RC facilities as a result of a reduction in their estimated useful lives as determined by Tinuum Group during the three months ended September 30, 2019. License royalties are recognized based upon a percentage of the per-ton, pre-tax margin as defined in the M-45 License, which is negatively impacted bysecond half of 2019. Further reducing the rate per ton was a decrease in net lease payments of approximately $1.0 million as a result of Tinuum Group restructuring RC facility contracted leases with its largest customer in the second half of 2019. As a result of higher depreciation. Based on the change in estimated useful lives,depreciation and lower lease payments, we expect that the lower royalty earnedrate per ton of RC through 2021 to be lower than historical rates.will continue in 2020 and 2021.

Legal and professional fees
Legal and professional fees decreased for the nine months ended September 30, 2020 compared to the same period in 2019 primarily due to decreased outsourced shared service costs, including legal, general consulting and audit and accounting fees of approximately $2.0 million, and a reduction in outsourced IT costs specific to the completion of the integration of Carbon Solutions of $0.7 million.
General and administrative
General and administrative expenses increased for the nine months ended September 30, 2020 compared to the same period in 2019 primarily due to an increase in headcount of personnel resulting from the Carbon Solutions Acquisition.

For the threenine months ended September 30, 2020, we recognized $20.5 million in equity earnings from Tinuum Group, which was equal to our proportionate share of Tinuum Group's net income for the period. For the nine months ended September 30, 2019, we recognized $11.7$50.8 million in equity earnings from Tinuum Group, which was equal to our proportionate share of Tinuum Group's net income of $11.7$52.4 million for the quarter. Duringperiod less the three months ended September 30, 2018, we recognized $8.1 millionrecovery of the cash distributions in equityexcess of the cumulative earnings from Tinuum Group compared to our proportionate shareas of Tinuum Group's net income of $15.8 million for the quarter.December 31, 2018. The difference between our pro-rata share of Tinuum Group's net income and our earnings from our Tinuum Group equity method investment as reported on the Condensed Consolidated Statements of Operations for the threenine months ended September 30, 20182019 was the result of cumulative distributions received from Tinuum Group being in excess of the carrying value of the investment, and therefore we recognized such excess distributions as equity method earnings in the period the distributions occurred.
For the threenine months ended September 30, 2019,2020, equity earnings from our interest in Tinuum Group were positively impacted by the addition of two new RC facilities during the second half of 2019 a new RC facility added during the three months ended September 30, 2019.2020 and the sale by Tinuum Group of its 49.9% remaining interest in an RC facility during thethree months ended September 30, 2020. However, ourequity earnings from Tinuum Group for the nine months ended September 30, 2020 decreased from the comparable period in 2019 primarily from two new RC facilities during the nine months ended September 30, 2019 that were negatively impacted fromrecognized as point-in-time sales. Further, the decrease in equity earnings was due to higher depreciation recognized of approximately $5.2 million for the nine months ended September 30, 2020 on all Tinuum Group RC facilities as a result of a reduction in theirRC facilities estimated useful lives as determined by Tinuum Group during the threesecond half of 2019. Further contributing to the decrease in equity earnings for the nine months ended September 30, 2019. Additionally, during2020 compared to the current year, there has been a reduction in coal consumption, largely due to lower natural gas prices, as well as unusually lower temperatures during the first half of 2019. As a result of the reduction in coal consumption, during the three nine
36


months ended September 30, 2019 Tinuum Group restructuredwas the restructuring of RC facility contracted leases with itsTinuum Group's largest customer, which decreased lease payments and equity earnings beginning in the three months ended September 30, 2019 and will also negatively impact our pro-rata sharesecond half of Tinuum Group's earnings in the future.
Further,2019. Furthermore, two coal-fired utilities in which Tinuum Group has invested RC facilities announced expected closures in the fourth quarter of 2019 and the associated leases of those facilities will terminateterminated during thisthat period. As a result of higher depreciation, reduced lease payments and closures of two utilities, we expect our pro-rata share of Tinuum Group’s earnings and distributions towill be lower in future periods. However, future incrementalfor the remainder of 2020 as well as 2021.
As of September 30, 2020 and 2019, Tinuum Group had 21 and 23 invested RC facilities, would positively impact our expectation of future earnings and distributions.respectively, that were generating revenues.
Equity earnings from our interest in Tinuum Services increased by $1.0 milliondecreased during the threenine months ended September 30, 20192020 compared to the threenine months ended September 30, 2018,2019.During the nine months ended September 30, 2020 and for those quarters,2019, Tinuum Services provided operating and maintenance services to 2220 and 1722 operating RC facilities, respectively.respectively, which was the primary driver in the decrease in equity earnings period over period. Tinuum Services derives earnings under fixed-fee arrangements as well as fee arrangements that are based on actual RC production, depending upon the specific RC facility operating and maintenance agreement.
Historically, we have earned Section 45 tax credits related to the production of RC, most significantly due to our direct and indirect ownership, through Tinuum Group, in the GWN REF RC facility ("GWN REF"). However, based on an agreement effective January 1, 2019 with its largest customer, which also has an ownership interest in Tinuum Group, substantially all of the tax credits earned from GWN REF will be allocated to this customer. As a result, our earned Section 45 tax credits for 2019 through 2021 will be substantially lower. For the three months ended September 30, 2019 and 2018, our Section 45 tax credits earned were $0.1 million and $1.6 million, respectively.
Interest expense
For the three months ended September 30, 2019, interest expense increased $1.3 million compared to the three months ended September 30, 2018 primarily due to interest expense incurred in the three months ended September 30, 2019 of $1.4 million related to a senior term loan (the "Senior Term Loan") entered into on December 7, 2018 to fund the Carbon Solutions Acquisition. This increase was comprised of stated interest on the Senior Term Loan principal of $0.9 million and interest expense related to debt discount and debt issuance costs associated with the Senior Term Loan of $0.5 million.


Income tax expense
For the three months ended September 30, 2019, we recorded income tax expense of $6.6 million compared to income tax expense of $3.9 million for the three months ended September 30, 2018. The income tax expense recorded for the three months ended September 30, 2019 was comprised of estimated federal income tax expense of $6.2 million and estimated state income tax expense of $0.4 million. The income tax expense recorded for the three months ended September 30, 2018 was comprised of estimated federal income tax expense of $2.9 million and estimated state income tax expense of $1.0 million.
The increase in income tax expense quarter over quarter was primarily due to an increase in the valuation allowance on deferred tax assets of $4.8 million for the three months ended September 30, 2019 compared to an increase of $1.4 million for the three months ended September 30, 2018 based on changes in forecasts as of September 30, 2019 and September 30, 2018, respectively, of future years' taxable income. Offsetting the net increase in income tax expense quarter over quarter was a decrease in state income tax expense of $0.6 million.

Consumables and consumables cost of revenue
During the nine months ended September 30, 2019, consumables revenues increased from the comparable period in 2018 primarily due to Carbon Solutions' operations. These operations also increased the total pounds of our consumables sold period over period.
Consumables cost of revenue was negatively impacted during the nine months ended September 30, 2019 due to $5.0 million of costs recognized as a result of the step-up in inventory fair value recorded from the Carbon Solutions Acquisition. As of June 30, 2019, the step-up in inventory was fully recognized in cost of revenue and consumables gross margin will not be impacted for the remainder of 2019.
During the nine months ended September 30, 2019, Consumables revenue and margins were negatively impacted by low coal-fired power dispatch driven by mild weather conditions as well as power generation from sources other than coal. In a recently updated forecast, the EIA revised downward by 7% its December 2018 forecast for 2019 coal-fired electricity-generating units.
License royalties, related party
For the nine months ended September 30, 2019 and 2018, there were 35.0 million tons and 26.4 million tons, respectively, of RC produced using the M-45 Technology under the M-45 License. The increase in license royalties was primarily due to obtaining additional third-party investors for two new RC facilities during 2018 and four new RC facilities during 2019, all of which use our M-45 License. The addition of new invested RC facilities in 2018 and 2019 resulted in an increase in both cash payments to Tinuum Group and the related tons subject to the M-45 License. Offsetting the net increase in license royalties for the nine months ended September 30, 2019 from additional facilities was a lower royalty per ton rate. This lower rate is attributable to higher depreciation recognized on all royalty bearing RC facilities during the three months ended September 30, 2019 as a result of a reduction in their estimated useful lives as determined by Tinuum Group during the three months ended September 30, 2019.

Payroll and benefits
Payroll and benefits expenses increased during the nine months ended September 30, 2019 compared to the same period in 2018 primarily due to an increase in headcount of personnel resulting from the Carbon Solutions Acquisition. Payroll and benefits expenses for the nine months ended September 30, 2018 also included restructuring expenses of $2.0 million.
Legal and professional fees
Legal and professional fees expenses increased during the nine months ended September 30, 2019 compared to the same period in 2018 primarily due to legal and professional fees associated with the integration of Carbon Solutions as well as expenses incurred related to on-going matters in the normal course of business.
General and administrative
General and administrative expenses increased during the nine months ended September 30, 2019 compared to the same period in 2018 due to an increase in general operating expenses, including an increase in outsourced IT costs related to the integration of Carbon Solutions of approximately $1.6 million. Further increases period over period of approximately $1.0 million related to rent and occupancy expense from additional leased office and warehouse space resulting from the Carbon Solutions Acquisition. Remaining increases period over period related to travel, insurance and recruiting expenses.
Depreciation and amortization
Depreciation and amortization expense increased during the nine months ended September 30, 2019 compared to the same period in 2018 due to the addition of long-lived assets and intangible assets acquired as part of the Carbon Solutions Acquisition, which contributed approximately $3.8 million and $0.7 million of depreciation and amortization, respectively, for the nine months ended September 30, 2019.

Earnings from equity method investments, and changes related thereto, are impacted by our most significant equity method investees: Tinuum Group and Tinuum Services.
For the nine months ended September 30, 2019, we recognized $50.8 million in equity earnings from Tinuum Group compared to our proportionate share of Tinuum Group's net income of $52.4 million for the period. The difference represents the cumulative earnings short-fall balance as of the end of the immediately preceding period, which was December 31, 2018. For the nine months ended September 30, 2018, we recognized $33.6 million in equity earnings from Tinuum Group compared to our proportionate share of Tinuum Group's net income of $42.3 million for the period. This difference was the result of cumulative distributions received from Tinuum Group being in excess of the carrying value of the investment, and therefore we recognized such excess distributions as equity method earnings in the period the distributions occurred. For the nine months ended September 30, 2019, equity earnings from Tinuum Group were negatively impacted from higher depreciation on all Tinuum Group RC facilities as a result of a reduction in their estimated useful lives as determined by Tinuum Group during the three months ended September 30, 2019, as described above.
For the nine months ended September 30, 2019, equity earnings from our interest in Tinuum Group were positively impacted by the addition of four new RC facilities during the nine months ended September 30, 2019. Further, revenues from two of these facilities were recognized immediately in 2019 as a result of Tinuum Group’s adoption of ASC Topic 606 - Revenue from Contracts with Customers ("ASC 606") and ASC Topic 842 - Leases ("ASC 842") as of January 1, 2019. However, our earnings were negatively impacted from higher depreciation on all Tinuum Group RC facilities as a result of a reduction in their estimated useful lives as determined by Tinuum Group during the three months ended September 30, 2019, as described above. As a result of a reduction in coal consumption, as noted above, during the three months ended September 30, 2019, Tinuum Group restructured RC facility contracted leases with its largest customer, which decreased lease payments beginning in the three months ended September 30, 2019 and will also negatively impact our pro-rata share of Tinuum Group's earnings in the future.
As of September 30, 2019 and 2018, Tinuum Group had 23 and 18 invested RC facilities, respectively, that were generating revenues. There were no 100% retained RC facilities as of September 30, 2019 or September 30, 2018, except for temporary operations of a retained RC facility prior to its lease or sale.
Equity earnings from our interest in Tinuum Services increased during the nine months ended September 30, 2019 compared to the nine months ended September 30, 2018.During the nine months ended September 30, 2019 and 2018, Tinuum Services provided operating and maintenance services to 22 and 17 operating RC facilities, respectively, which was the driver in the increase in equity earnings. Tinuum Services derives earnings under fixed-fee arrangements as well as fee arrangements that are based on actual RC production, depending upon the specific RC facility operating and maintenance agreement.
During the nine months ended September 30, 2019 and 2018, our Section 45 tax credits earned were $0.2 million and $5.3 million, respectively. As discussed above, the substantial decrease period over period was primarily due to an agreement between Tinuum Group and its largest customer effective January 1, 2019 that allocated substantially all of the tax credits earned from GWN REF to this customer, who also has an ownership interest in Tinuum Group.
Interest expense
For the nine months ended September 30, 2019,2020, interest expense increased $4.7decreased $2.8 million compared to the nine months ended September 30, 20182019 primarily due to interest expense incurred in the nine months ended September 30, 20192020 related to the Senior Term Loan.Loan, as the principal balance was reduced from payments of $24.0 million made during the period from September 30, 2019 to September 30, 2020. The increase was mostly comprised of stated interest on the Senior Term Loan principal of $3.3 million andremaining decrease in interest expense related to debt discount and debt issuance costs associated withlower 453A interest from a reduction in the Senior Term Loan of $1.3 million.


deferred balance related to 453A during the period from September 30, 2019 to September 30, 2020. 
Income tax expense
For the nine months ended September 30, 2019,2020, we recorded income tax expense of $14.9$1.3 million compared to income tax expense of $5.2$14.9 million for the nine months ended September 30, 2018.2019. The income tax expense recorded for the nine months ended September 30, 2020 was comprised of estimated federal income tax expense of $1.4 million. The income tax expense recorded for the nine months ended September 30, 2019 was comprised of estimated federal income tax expense of $13.2 million and estimated state income tax expense of $1.7 million. The income tax expense recorded for the nine months ended September 30, 2018 was comprised of estimated federal income tax expense of $3.4 million and estimated state income tax expense of $1.8 million.
The increasedecrease in income tax expense period over period was primarily due to: (1) an increase in forecasted pre-taxto a pretax loss for the nine months ended September 30, 2020 of $19.4 million compared to pretax income period over period from the Carbon Solutions Acquisition and the addition of new invested RC facilities duringfor the nine months ended September 30, 2019 which resulted in an increaseof $41.4 million. Offsetting the decrease in income tax expense period over period was an increase in the valuation allowance on deferred tax assets of $3.2$5.1 million fromfor the nine months ended September 30, 2018; and (2)2020 compared to an increase in the valuation allowance of on deferred tax assets of $3.8 million for the nine months ended September 30, 2019 compared to a decrease in the valuation allowance of $2.7 million for the nine months ended September 30, 2018 based on changes in forecasts of future years' taxable income as of September 30, 20192020 and September 30, 2018,2019, respectively.

Non-GAAP Financial Measures
To supplement the Company'sour financial information presented in accordance with U.S.accounting principles generally accepted accounting principles, or GAAP,in the U.S. ("GAAP"), we are providing non-GAAP measures of certain financial performance. These non-GAAP measures include Consolidated Adjusted EBITDA, PGI Segment Adjusted EBITDA and RC Segment Adjusted EBITDA. The CompanyWe have included non-GAAP measures because management believes that they help to facilitate comparison of operating results between periods. The Company believesWe believe the non-GAAP measures provide useful information to both management and users of the financial statements by excluding certain expenses and gains and losses that may not be indicative of core operating results and business outlook. These non-GAAP measures are not in accordance with, or an alternative to, measures prepared in accordance with GAAP and may be different from non-GAAP measures used by other companies. In addition, these non-GAAP measures are not based on any comprehensive set of accounting rules or principles. These measures should only be used to evaluate the Company'sour results of operations in conjunction with the corresponding GAAP measures.
The Company has definedWe define Consolidated Adjusted EBITDA as net income (loss), adjusted for the impact of the following items that are either non-cash or that the Company doeswe do not consider representative of itsour ongoing operating performance: depreciation, amortization, depletion and accretion, interest expense, net and income tax expense.expense; then reduced by the non-cash impact of equity earnings from equity method investments and increased by cash distributions from equity method investments and impairment of long-lived assets. Because Consolidated Adjusted EBITDA omits certain non-cash items, the Company believeswe believe that the measure is less susceptible to variances that affect the Company'sour operating performance.
We define PGI Segment Adjusted EBITDA is calculated as Segment operating income (loss) adjusted for the impact of the following items that are either non-cash or that the Company doeswe do not consider representative of its ongoing operating performance: depreciation, amortization, depletion and accretion, and interest expense, net.net and impairment of long-lived assets. When used in conjunction with

GAAP financial measures, PGI Segment Adjusted EBITDA is a supplemental measure of operating performance that management believes is a useful measure for the Company'seach of our PGI segmentand RC segment's performance relative to the performance of its competitors as well as performance period over period. Additionally, the Company believeswe believe the measure is less susceptible to variances that affect itsour operating performance results.
The Company presents ConsolidatedWe define RC Segment Adjusted EBITDA andas RC Segment EBITDA reduced by the non-cash impact of equity earnings from equity method investments and increased by cash distributions from equity method investments.
We present these non-GAAP measures because the Company believeswe believe they are useful as supplemental measures in evaluating the performance of the Company'sour operating performance and provide greater transparency into the results of operations. The Company's managementManagement uses Consolidated EBITDA and Segment EBITDA as factorsthese non-GAAP measures in evaluating the performance of itsour business.
TheWith the exception of impairment, the adjustments to Consolidated Adjusted EBITDA, PGI Segment Adjusted EBITDA and RC Segment Adjusted EBITDA in future periods are generally expected to be similar. Consolidated EBITDA and Segment EBITDAThese non-GAAP measures have limitations as analytical tools and these measures should not be considered in isolation or as a substitute for analyzing the Company'sour results as reported under GAAP.

Business Segments
As of September 30, 2019,2020, we have two reportable segments: (1) RC and (2) PGI. The business segment measurements provided to and evaluated by our chief operating decision maker are computed in accordance with the principles listed below:
The accounting policies of the operating segments are the same as those described in the summary of significant accounting policies in the 20182019 Form 10-K.
Segment revenues include equity method earnings and losses from our equity method investments.
Segment operating income (loss) includes segment revenues and allocation of certain "Corporate general and administrative expenses," which include Payroll and benefits, Rent and occupancy, Legal and professional fees, and General and administrative.
RC segment operating income includes interest expense directly attributable to the RC segment.
The principal products and services of our segments are:
1.
RC - Our RC segment derives its earnings from equity method investments as well as royalty payment streams and other revenues related to enhanced combustion of and reduced emissions of both NOX and mercury from the burning of coal. Our equity method investments related to the RC segment include Tinuum Group, Tinuum Services and other immaterial equity method investments. Segment revenues include our equity method earnings (losses) from our equity method investments and royalty earnings from Tinuum Group. These earnings are included within the Earnings from equity method investments and License royalties, related party line items in the Condensed Consolidated Statements of Operations. Key drivers to the RC segment performance are the produced and sold RC from both operating and retained RC facilities, royalty-bearing tonnage and the number of operating (leased or sold) and retained RC facilities. These key drivers impact our earnings and cash distributions from equity method investments.

These key drivers impact our earnings and cash distributions from equity method investments.
2.PGI - Our PGI segment includes revenues and related expenses from the sale of consumable products that utilize AC and chemical technologies. These options provide coal-powered utilities and industrial boilers with mercury control solutions working in conjunction with pollution control equipment systems, generally without the requirement for significant ongoing capital outlays. These amounts are included within the respective revenues and cost of revenue line items in the Condensed Consolidated Statements of Operations.
2.PGI - Our PGI segment primarily includes revenues and related expenses from the sale of consumable products that utilize PAC chemical technologies. These options provide coal-powered utilities and industrial boilers with mercury control solutions working in conjunction with activated carbon injection ("ACI") and dry sorbent injection ("DSI") systems and other pollution control equipment, generally without the requirement for significant ongoing capital outlays. These amounts are included within the respective revenues and cost of revenue line items in the Condensed Consolidated Statements of Operations.
Management uses segment operating income (loss) to measure profitability and performance at the segment level. Management believes segment operating income (loss) provides investors with a useful measure of our operating performance and underlying trends of the businesses. Segment operating income (loss) may not be indicative of our overall consolidated performance and therefore, should be read in conjunction with our Condensed Consolidated Statements of Operations.

For the three months ended September 30, 20192020 and September 30, 20182019
RC earnings increaseddecreased primarily due to an increasea decrease in equity earnings in Tinuum Group duringfor the three months ended September 30, 20192020 compared to the samecorresponding quarter in 2018, as presented above.2019.
For the three months ended September 30, 2019, we recognized $11.7 million in equity earnings from Tinuum Group, which was equal to our proportionate share of Tinuum Group's net income of $11.7 million for the quarter. During the three months ended September 30, 2018, we recognized $8.1 million in equity earnings from Tinuum Group compared to our proportionate share of Tinuum Group's net income of $15.8 million for the quarter. The difference between our pro-rata share of Tinuum Group's net income and our earnings from our Tinuum Group equity method investment as reported on the Condensed


Consolidated Statements of Operations for the three months ended September 30, 2018 was the result of cumulative distributions received from Tinuum Group being in excess of the carrying value of the investment, and therefore we recognized such excess distributions as equity method earnings in the period the distributions occurred.
For the three months ended September 30, 2019,2020, equity earnings from our interest in Tinuum Group were positively impacted by the addition of two new RC facilities during the second half of 2019, a new RC facility added during the three months ended September 30, 2019.2020 and the sale by Tinuum Group of its 49.9% remaining interest in an RC facility during thethree months ended September 30, 2020.

decreased from the comparable quarter in 2019 primarily from higher depreciation recognized of approximately $0.4 million for the three months ended September 30, 2020 on all Tinuum Group RC facilities as a result of a reduction in theirRC facilities estimated useful lives as determined by Tinuum Group during the three months ended September 30, 2019. As a resultFurther contributing to the decrease in equity earnings quarter over quarter was the restructuring of RC facility leases with Tinuum Group's largest customer, which decreased lease payments and equity earnings beginning in the reductionsecond half of 2019. We believe the increase in coal consumption described above, duringdepreciation and the decrease in lease payments will negatively impact equity earnings for the remainder of 2020 as well as 2021.
For the three months ended September 30, 2020 and 2019, we recognized $7.3 million and $11.7 million, respectively, in equity earnings from Tinuum Group, restructured RC facility contracted leases with its largest customer, which decreased lease payments beginning inwas equal to our proportionate share of Tinuum Group's net income for those quarters.

Earnings from Tinuum Services for the three months ended September 30, 2019 increaseddecreased compared to the samecorresponding quarter in 20182019 primarily due to an increasea decrease in the number of operating RC facilities from 17 to 22 in which Tinuum Services provides operating and maintenance services.services from 22 to 20.
RC earnings were positively impacted duringAs noted above, for the three months ended September 30, 20192020, RC earnings were impacted by an increasea decrease in license royalties related toearned from Tinuum Group's use of ourGroup under the M-45 License. DuringFor the three months ended September 30, 20192020 and 2018,2019, there were 14.514.6 million tons and 10.514.5 million tons, respectively, of RC produced using the M-45 Technology. The increase in Royalty revenue was driven by both an increase in payments to Tinuum Group and the related tons subject to the M-45 License. Offsetting the net increase in Royalty revenue for the three months ended September 30, 2019 from additional facilitiesWhile tonnage increased slightly period over period, there was a lowerreduction in the royalty rate per ton rate fromprimarily attributable to higher depreciation recognized for the three months ended September 30, 2019of approximately $0.2 million on all royalty bearing RC facilities as a result of a reduction in their estimated useful lives as determined by Tinuum Group during the three months ended September 30, 2019.

For the nine months ended September 30, 2020, we recognized $20.5 million in equity earnings from Tinuum Group, which was equal to our proportionate share of Tinuum Group's net income for the period. For the nine months ended September 30, 2019, we recognized $50.8 million in equity earnings from Tinuum Group, comparedwhich was equal to our proportionate share of Tinuum Group's net income of $52.4 million for the period.

ForThe difference between our pro-rata share of Tinuum Group's net income and our earnings from our Tinuum Group equity method investment as reported on the Condensed Consolidated Statements of Operations for the nine months ended September 30, 2018, we recognized $33.6 million in equity earnings from Tinuum Group compared to our proportionate share of Tinuum Group's net income of $42.3 million for the period. This difference2019 was the result of cumulative distributions received from Tinuum Group being in excess of the carrying value of the investment, and therefore we recognized such excess distributions as equity method earnings in the period the distributions occurred.
For the nine months ended September 30, 2019,2020, equity earnings from our interest in Tinuum Group were positively impacted by the addition of fourtwo new RC facilities during the second half of 2019, a new RC facility added during the three months ended September 30, 2020 and the sale by Tinuum Group of its 49.9% remaining interest in an RC facility during thethree months ended September 30, 2020. However, equity earnings from Tinuum Group for the nine months ended September 30, 2020 decreased from the comparable period in 2019 primarily from two new RC facilities during the nine months ended September 30, 2019. Further, revenues from two of these facilities2019 that were recognized immediatelyas point-in-time sales. Further, the decrease in 2019 as a result of Tinuum Group’s adoption of ASC Topic 606 - Revenue from Contracts with Customers and ASC Topic 842 - Leases as of January 1, 2019. However, ourequity earnings were negatively impacted fromwas due to higher depreciation recognized of approximately $5.2 million for the nine months ended September 30, 20192020 on all Tinuum Group RC facilities as a result of a reduction in theirRC facilities' estimated useful lives as determined by Tinuum Group during the three months ended September 30, 2019, as described above. As a resultsecond half of a reduction2019. Further contributing to the decrease in coal consumption, as noted above, during the three months ended September 30, 2019, Tinuum Group restructured RC facility contracted leases with its largest customer, which decreased lease payments beginning in the three months ended September 30, 2019 and will also negatively impact our pro-rata share of Tinuum Group'sequity earnings in the future.
Earnings from Tinuum Services for the nine months ended September 30, 2019 increased2020 compared to the same period in 2018 primarily due to an increasenine months ended September 30, 2019 was the restructuring of RC facility leases with Tinuum Group's largest customer, which decreased lease payments and equity earnings beginning in the numbersecond half of 2019. Furthermore, two coal-fired utilities in which Tinuum Group has invested RC facilities announced expected closures in the fourth quarter of 2019 and the associated leases of those facilities terminated during that period. As a result of higher depreciation, reduced lease payments and closures of two utilities, we expect our pro-rata share of Tinuum Group’s earnings will be lower for the remainder of 2020 as well as 2021.
As of September 30, 2020 and 2019, Tinuum Group had 21 and 23 invested RC facilities, respectively, that were generating revenues.
Equity earnings from our interest in Tinuum Services decreased during the nine months ended September 30, 2020 compared to the nine months ended September 30, 2019.During the nine months ended September 30, 2020 and 2019, Tinuum Services provided operating and maintenance services to 20 and 22 operating RC facilities, from 17 to 22respectively, which was the primary driver in whichthe decrease in equity earnings.

RC earnings were positivelynegatively impacted during the nine months ended September 30, 20192020 by an increasea decrease in royalties related toearned from Tinuum Group's use of ourGroup under the M-45 License. During the nine months ended September 30, 20192020 and 2018,2019, there were 35.035.7 million tons and 26.435.0 million tons, respectively, of RC produced using the M-45 Technology. The increase in Royalty revenue was primarily driven by an increase in both payments to Tinuum Group and the related tons subject to the M-45 License. Offsetting the net increase in Royalty revenue for the nine months ended September 30, 2019 from additional facilitiesWhile tonnage increased period over period, there was a lowerreduction in the royalty rate per ton rate fromprimarily attributable to higher depreciation recognized for the nine months ended September 30, 2019of approximately $1.8 million on all royalty bearing RC facilities as a result of a reduction in their estimated useful lives as determined by Tinuum Group duringin the three months ended September 30,second half of 2019. Further reducing the rate per ton was a decrease in net lease payments of approximately $1.0 million as a result of Tinuum Group restructuring RC facility contracted leases with its largest customer in the second half of 2019. As a result of higher depreciation and lower lease payments, we expect that the lower royalty rate per ton will continue in 2020 and 2021.
Future earnings and growth within the RC segment will continue to be impacted by coal-fired dispatch, and invested facilities with leases subject to periodic renewals being terminated, repriced, or otherwise subject to renegotiated terms.

Liquidity and Capital Resources
Overview of Factors Affecting Our Liquidity
During the nine months ended September 30, 2019,2020, our liquidity position was positively affected primarily due to distributions from Tinuum Group and Tinuum Services, royalty payments from Tinuum Group and borrowing availability under our bank ("Lender") line of credit ("Line of Credit").
Our principal sources of cash include:included:
cash on hand;
distributions from Tinuum Group and Tinuum Services;
royalty payments from Tinuum Group; and
operations ofcash proceeds received under the PGI segment.Paycheck Protection Program ("PPP") administered by the U.S. Small Business Administration ("SBA").
Our principal uses of cash duringfor the nine months ended September 30, 20192020 included:
payment of dividends;
payment of debt principal and interest;
repurchases of shares of common stock; and
payment of dividends;
payment of debt principal and interest; and
our business operating expenses, including federal and state tax payments, and cash severance payments.payments and costs associated with COVID-19.
Our ability to continue to generate sufficient cash flow required to meet ongoing operational needs and obligations, as well as
capital expenditures, future expectedpotential dividend payments and potential future share repurchases depends uponon several factors, including executing on
our contracts and initiatives, receiving license royalty payments from Tinuum Group and distributions from Tinuum Group and Tinuum
Services, and increasing our share of the market for PGI consumables, as well asincluding expanding our overall PACAC business into
additional adjacent markets. Increased distributions from Tinuum Group will likely be dependent upon both preserving existing
contractual relationships and securing additional tax equity investors for those Tinuum Group facilities that are currently not operating.
Due to the Carbon Solutions Acquisition, we expect our use of liquidity for capital expenditures will increase in future periods. Carbon Solutions has historically incurred costs both forWe incur significant recurring capital expenditures for itsour AC manufacturing facility and for mine development at itsour lignite mine. Going forward,For 2020, we anticipate additional materialthat our capital resourcesexpenditures will be neededlower than 2019 as we will not have significant planned maintenance expenditures for the balance of 2020 at our lignite mine as we did in 2019. For 2021, we expect to maintain or improveincur capital assets. We incurred expenditures relatedabove the level of 2020 primarily due to planned maintenance at our lignite mine.
Our liquidity was negatively impacted from COVID-19 due to increased operating losses in our PGI segment from higher operating costs as a result of measures taken to support our ability to deliver as a critical infrastructure business, primarily from sequestration efforts and "hazard pay," which is a premium on wages, for a substantial number of our AC manufacturing facility duringemployees, and overall plant operating inefficiencies. However, in April 2020, we took steps to enhance our short-term liquidity through the nine months ended September 30, 2019.

Cash distributions from Tinuum Group for the nine months ended September 30, 2020 decreased by $15.0 million compared to the nine months ended September 30, 2019 primarily due to reductions in lease payments received by Tinuum Group from its largest customer as a result of renegotiations of certain leases, which occurred in the second half of 2019 between Tinuum Group and 2018:

this customer, and the shuttering of two coal-fired utilities in the fourth quarter of 2019 where two invested RC facilities were operating.
Future cash flows from Tinuum through 2021 are expected to range from $150$90 million to $175 million, a decrease from the previously reported range of $175 to $200$110 million. The key drivers in achieving these future cash flows are based on the following:
2321 invested facilities as of September 30, 20192020 and inclusive of all net Tinuum cash flows (distributions and license
44


royalties), offset by estimated federal and state income tax payments and 453A interest payments.
Expected future cash flows from Tinuum Group are based on the following key assumptions:
Tinuum Group continues to not operate retained facilities;
Tinuum Group does not have material unexpected capital expenditures or unusual operating expenses;
Tax equity lease renewals on invested facilities are not terminated or repriced; and
Coal-fired power generation remains consistent with contractual expectations.
As noted above, recently, two coal-fired utilities where Tinuum has invested RC facilities operating were announcedPPP Loan
On April 21, 2020, we entered into a loan (the "PPP Loan") under the PPP through BOK, NA dba Bank of Oklahoma (the "Lender") providing for closure,$3.3 million in proceeds, which amount was funded on April 21, 2020. The PPP Loan matures April 21, 2022 and provides for 18 monthly payments of principal and interest commencing on November 21, 2020. The interest rate on the PPP Loan is expected1.00%. The PPP Loan is unsecured and contains customary events of default relating to, occuramong other things, payment defaults, making materially false and misleading representations to the SBA or the Lender, or breaching the terms of the PPP Loan. The occurrence of an event of default may result in the fourth quarterrepayment of 2019.all amounts outstanding, collection of all amounts owing from us, or filing suit and obtaining judgment against us. The shutteringPPP Loan may be forgiven subject to the terms of these facilitiesthe PPP and approval by the SBA.
Our business has negatively impactedbeen classified as an essential business and therefore we continue to operate on a modified basis to comply with governmental restrictions and public health authority guidelines. In April 2020, we sequestered approximately 60 employees to continue to run our expectations relatedmanufacturing plant and build-up inventory in order to future cash flows if we are unablesupply our customers. This resulted in additional costs as the sequestered employees received hazard pay. We used proceeds from the PPP Loan to move the existing RC facilities to new utilities. Also as noted above, Tinuum Group and its largest customer agreed to certain reductions in overall lease payments for the period from


October 2019 to December 2021, which will negatively impact future cash flows. These factors will result in a net reduction infund our pro-rata share of expected future RC cash flows. However, with the addition of two RC facilities during the three months ended September 30, 2019, future cash flows are expected to decrease by approximately $10.0 million from September 2019 to December 2021.payroll costs.
Senior Term Loan
On December 7, 2018, we and ADA-ES, Inc. ("ADA"), a wholly-owned subsidiary, and certain other subsidiaries of the Company as guarantors, The Bank of New York Mellon as administrative agent, and Apollo Credit Strategies Master Fund Ltd and Apollo A-N Credit Fund (Delaware) L.P. (collectively "Apollo”), affiliates of a beneficial owner of greater than five percent of our common stock and a related party, entered into the Term Loan and Security Agreement (the "Senior Term Loan") in the amount of $70.0 million, less original issue discount of $2.1 million. Proceeds from the Senior Term Loan were used to fund the acquisition of Carbon Solutions Acquisition as disclosed in Note 2.8. We also paid debt issuance costs of $2.0 million related to the Senior Term Loan. The Senior Term Loan has a term of 36 months and bears interest at a rate equal to 3-month LIBOR (subject to a 1.5% floor) + 4.75% per annum, which is adjusted quarterly to the current 3-month LIBOR rate, and interest is payable quarterly in arrears. Quarterly principal payments of $6.0 million are required and commenced in March 2019, and we may prepay the Senior Term Loan at any time without penalty. The Senior Term Loan is secured by substantially all of our assets, including the cash flows from Tinuum Group and Tinuum Services (collectively, the "Tinuum Entities"), but excluding our equity interests in those Tinuum entities. During the nine months ended September 30, 2019,2020, we made principal payments of $24.0$18.0 million.
The Senior Term Loan includes, among others, the following covenants: (1) Beginning December 31, 2018 and as of the end of each fiscal quarter thereafter, we must maintain a minimum cash balance of $5.0 million and shall not permit "expected future net cash flows from the refined coal business" (as defined in the Senior Term Loan) to be less than 1.75 times the outstanding principal amount of the Senior Term Loan; (2) Beginning in January 2019, annual collective dividends and buybacks of shares of our common stock in an aggregate amount, not to exceed $30.0 million, is permitted so long as (a) no default or event of default exists under the Senior Term Loan and (b) expected future net cash flows from the refined coal business as of the end of the most recent fiscal quarter exceed $100.0 million.
Pursuant to entering into the PPP Loan, on April 20, 2020, we and Apollo executed the First Amendment to the Senior Term Loan, which permitted us to enter into the PPP Loan.

Customer Supply Agreement and Acquisition of Marshall Mine
We believe the Supply Agreement will provide material incremental volume and capture lower operating cost efficiencies of our manufacturing plant providing additional sources of operating cash flows in the future. Full and partial reimbursements on capital expenditures will help limit our uses of investing cash flows. Further, we intend to fund the remaining portion of the Reclamation Costs from cash on hand as well as cash generated from the Supply Agreement.

PART II. OTHER INFORMATION
Item 1. Legal Proceedings
From time to time, we are involved in litigation, claims and other proceedings related to the conduct of our business. LitigationInformation with respect to this item may be found in Note 13 "Commitments and other disputes are inherently unpredictable and subjectContingencies" to substantial uncertainties and unfavorable resolutions could occur. Nonethe consolidated financial statements included in Item 1 of these matters, either individually or in the aggregate, currently is material to us.Part I of this Quarterly Report.
Item 1A. Risk Factors
There are no material updates to our risk factors as disclosed in the 20182019 Form 10-K except as set forth below. This risk factor should be read together with the risk factors in the 2019 Form 10-K.
The COVID-19 pandemic and ensuing economic downturn has affected, and is expected to continue to affect and pose risks to our business, results of operations, financial condition and cash flows; and other epidemics or outbreaks of infectious diseases may have a similar impact.
In March 2020, the WHO declared the outbreak of COVID-19 a global pandemic, which continues to spread throughout the United States ("U.S.") and the world and has resulted in authorities implementing numerous measures to contain the virus, including travel bans and restrictions, quarantines, shelter-in-place orders, and business limitations and shutdowns. We have been designated by CISA as a critical infrastructure supplier to the energy sector. This designation provides some latitude in continuing to conduct our business operations compared to companies in other industries and markets. While we are unable to accurately predict the full impact that COVID-19 will have on our results from operations, financial condition, liquidity and cash flows due to numerous uncertainties, including the duration and severity of the pandemic and containment measures, our compliance with these measures has impacted our day-to-day operations and could disrupt our business and operations, as well as that of our key customers, suppliers and other counterparties, for an indefinite period of time. To support the health and well-being of our employees, customers, partners and communities, a vast majority of our employees not directly involved in operating our plant, have been working remotely since March 2020. In addition, many of our customers are working remotely, which may delay the timing of some orders and deliveries expected in the second quarter of 2020 and beyond. The disruptions to our operations caused by COVID-19 may result in inefficiencies, delays and additional costs in our manufacturing, sales, marketing, and customer service efforts that we cannot fully mitigate through remote or other alternative work arrangements. Although such disruptions did not have a material adverse impact on our financial results for the first quarter of fiscal 2020, we incurred additional operating costs for the second quarter of fiscal year 2020, which included hazard pay, cleaning costs and sequestration costs related to our operating plant personnel. For the balance of 2020, we may see reduced demand for our products due to reduced interaction with our customers and our inability to target new customers and markets.
More generally, the pandemic raises the possibility of an extended global economic downturn and has caused volatility in financial markets, which could affect demand for our products and services and impact our results and financial condition even after the pandemic is contained and the shelter-in-place orders are lifted. For example, a decrease in orders in a given period could negatively affect our revenues in future periods, particularly if experienced on a sustained basis. We will continue to evaluate the nature and extent of the impact of COVID-19 to our business.
As previously disclosed, in April 2020, we entered into a loan (the "PPP Loan") in the amount of $3.3 million through a bank under the Paycheck Protection Program sponsored by the U.S. Small Business Administration ("SBA"). The PPP loan became available to us pursuant to the Coronavirus Aid, Relief, and Economic Security Act and is administered by the SBA. We entered into the PPP Loan to provide additional liquidity in light of our COVID-19-related higher employee costs. Proceeds from the PPP Loan were used to cover a portion of our existing payroll and related expenses, including sequestration pay for certain employees, as well as certain other operating costs as permitted under the Paycheck Protection Program. We expect that current cash and cash equivalent balances, inclusive of the PPP Loan, and cash flows that are generated from operations will be sufficient to meet our working capital needs and other capital and liquidity requirements for at least the next 12 months. However, if our business is more adversely impacted by COVID-19 than we expect, and our personnel costs remain higher than budgeted, our cash needs could increase.
Further, we assessed the impact on our existing internal control over financial reporting as of March 31, 2020 and going forward under the current state of COVID-19. We performed procedures to ensure that existing internal control over financial reporting was operating effectively as March 31, 2020 and will continue to operate effectively for the foreseeable future. Such procedures included, but were not limited to, developing a COVID- 19 risk assessment identifying the risks of fraud, changes required in our internal control framework as well as other business information technology and cybersecurity risks. As a result of these procedures and conclusions reached, we did not implement any changes to our internal control over financial reporting as of September 30, 2020.
