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").

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, ~~2018~~2019 (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 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 three months ended March 31, 2018, Stock Options to purchase 0.2 million of common stock, 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 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 ~~makes~~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 ~~2018~~2019 Form 10-K. 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 that would require an update to its estimate 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 March 31, ~~2019,~~2020, Tinuum Group has 20 invested RC facilities of which 118 are leased to a single customer. A majority of these leases are periodically ~~renewed and~~renewed. Further, the ability to generate Section 45 tax credits related to Tinuum's RC facilities expires in 2021. The loss of ~~this~~the single customer by Tinuum Group or the expiration of Section 45 tax credits would have a significant adverse impact on ~~its~~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.

(Unaudited)

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.

of the periods presented.

New Accounting Standards

~~Recently Adopted~~

~~In February 2016, the FASB issued ASU 2016-02,~~ ~~Leases~~ ~~(Topic 842) ("ASU 2016-2"), 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" 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
(in thousands) December 31, 2018 Adoption January 1, 2019
Balance Sheet
Other long-term assets $ 7,993
$ 6,956
$ 14,949
Other liabilities $ 50,058
$ 3,085
$ 53,143
Other long-term liabilities $ 940
$ 3,871
$ 4,811

~~See Note 6 for additional disclosures required under ASC 842 in the year of adoption.~~

~~Additionally, Tinuum Group adopted ASU 2014-09 (Topic 606),~~ ~~Revenue from Contracts with Customers~~ ("ASU 2014-09") and ASU 2016-02 as of January 1, 2019. As a result of Tinuum Group’s adoption, the Company recorded a cumulative effect increase of $28.8 million to Retained earnings as of January 1, 2019 related to the Company's percentage of Tinuum Group's cumulative effect adjustment. As a result of this adjustment, the Company increased its investment balance in Tinuum Group in the amount of $37.2 million and established a deferred tax liability of $8.4 million. The Company no longer has cumulative cash distributions in excess of our cumulative pro-rata share of Tinuum Group's net income. Therefore, the Company recognized equity earnings by recording its pro-rata share of Tinuum Group’s net income rather than based upon cash distributions for the three months ended March 31, 2019.

~~In June 2018, the FASB issued ASU No. 2018-07-Compensation-Stock Compensation (Topic 718): Improvements to Non-Employee Share-Based Payment Accounting~~, to align accounting for non-employee share-based payment transactions with the guidance for share-based payments to employees. Under the new standard, the measurement of equity-classified non-employee awards will be fixed at the grant date. The Company adopted this standard on January 1, 2019 and it did not have a material impact on the Company's financial statements and disclosures.

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.

Note 2 - Acquisition

As described in Note 1, on the Acquisition Date, the Company completed the acquisition of Carbon Solutions ~~Acquisition~~(the "Carbon Solutions Acquisition") for a total purchase price 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 the purchase consideration totaled $66.5 million, ~~and consisted~~less cash acquired of ~~cash of $65.8~~$3.3 million, and ~~an additional purchase adjustment amount payable to Carbon Solutions' secured lender~~the assumption of ~~$0.7 million, which was paid in March 2019. The Purchase Price was adjusted by assumed~~ debt and contractual commitments of $11.8 ~~million, and less cash acquired of $3.3~~ million. The Company also paid $4.5 million in acquisition-related costs (or transaction costs) ~~during the year ended December 31, 2018.~~. The Company funded the cash consideration from cash on hand and the proceeds from the Term Loan and Security Agreement (the "Senior Term Loan") in the principal amount of $70.0 million, as more fully described in Note 5.

~~During the three months ended March 31, 2019, there were no material adjustments~~

Note 4 - Equity Method Investments

Tinuum Group, LLC

The Company's ownership interest in Tinuum Group was 42.5% as of March 31, ~~2019~~2020 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 RC that lower emissions and ~~therefore~~also qualify for Section 45 tax credits. Tinuum Group has been determined to be a variable interest entity ("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.

The following table summarizes the results of operations of Tinuum Group:

~~The~~For the three months ended March 31, 2020, the Company recognized its pro-rata share of Tinuum Group's net income available to its members for the respective period. For the three months ended March 31, 2019, the Company recognized its pro-rata share of Tinuum Group's net income available to its members for the period, less the amount necessary to recover the cumulative earnings short-fall balance as of the end of the immediately preceding period, which was December 31, 2018. For the three months ended March 31, 2019, the difference between the Company's proportionate share of Tinuum Group's net income available to members (at its equity interest of 42.5%) ~~during the three months ended March 31, 2018, as presented in the table below,~~ and the Company's earnings from its Tinuum Group equity method investment as reported in the Condensed Consolidated Statements of Operations relates to the Company receiving distributions in excess of the carrying value of the equity investment, and therefore recognizing such excess distributions as equity method earnings in the period the distributions ~~occur, as discussed below.~~occur.

~~Thus, the amount of equity earnings or loss reported on the Company's~~Notes to Condensed Consolidated Statement of Operations may differ from a mathematical calculation of net income or loss attributable to the equity interest based upon the factor of the equity interest and the net income or loss attributable to members as shown on Tinuum Group’s statement of operations. Additionally, for periods during which the carrying value of the Company's investment in Tinuum Group is greater than zero, distributions from Tinuum Group are reported on the Condensed ConsolidatedFinancial Statements of Cash Flows as "Distributions from equity method investees, return on investment" within Operating cash flows. For periods during which the carrying value of the Company's investment in Tinuum Group is zero, such cash distributions are reported on the Condensed Consolidated Statements of Cash Flows as "Distributions from equity method investees in excess of investment basis" within Investing cash flows.

Senior Term Loan

On December 7, 2018, the Company, 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”~~"Apollo"), affiliates of a beneficial owner of greater than five percent of the Company's common stock and a related party, entered into 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 Carbon Solutions Acquisition as disclosed in Note 2. The Company 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 were required beginning in March 2019, and the Company may prepay the Senior Term Loan at any time without penalty. The Senior Term Loan is secured by substantially all of the assets of the Company,

including the cash flows from Tinuum Group and Tinuum Services (collectively, the "Tinuum Entities"), but excluding the Company's equity interests in the Tinuum entities.

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, the Company 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 Company shares 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.

Line of Credit

On ~~September 30,~~December 7, 2018, ~~ADA,~~ADA-ES, Inc. ("ADA"), a wholly-owned subsidiary of the Company, as borrower, the Company, as guarantor, and a bank (the "Lender") entered into an amendment ~~(the "Twelfth Amendment")~~ to the 2013 Loan and Security Agreement (the "Line of Credit"). The Twelfth Amendment decreased the borrowing availability of the Line of Credit to $5.0 million due to decreased collateral requirements, extended the maturity date of the Line of Credit to September 30, 2020 and permitted the Line of Credit to be used as collateral (in place of restricted cash) for letters of credit ("LC's") up to $5.0 million related to equipment projects and certain other agreements. Under the Twelfth Amendment, there was no minimum balance requirement based on the Company meeting certain conditions and maintaining minimum trailing twelve-month EBITDA (earnings before interest, taxes, depreciation and amortization), as previously defined in the "Eleventh Amendment" to the Line of Credit, of $24.0 million.

~~On December 7, 2018, ADA, as borrower, the Company, as guarantor, and the Lender entered into an~~This amendment ~~to the Line of~~

~~Credit, which~~ provided, among other things, for ADA to be able to enter into the Senior Term Loan as a guarantor so long as

the principal amount of the Senior Term Loan ~~does~~did not exceed $70.0 million. Additionally, the financial covenants in the Line

of Credit were amended and restated to be consistent with the ~~aforementioned~~ Senior Term Loan covenants, including

maintaining a minimum cash balance of $5.0 million.

As of March 31, ~~2019,~~2020, there were no outstanding borrowings under the Line of Credit.

Note 6 - Leases

The financial statement impact from the adoption of ASC 842 as of January 1, 2019 is due to recording the 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.

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 March 31, ~~2019,~~2020, the Company has obligations under finance and operating leases in the amounts of ~~$7.8~~$6.4 million and ~~$6.3~~$4.6 million, respectively. ROU assets under finance leases are primarily 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 March 31, ~~2019,~~2020, the Company has ~~ROU~~right of use ("ROU") assets, net of accumulated amortization, under finance leases and operating leases of ~~$7.5~~$5.4 million and ~~$6.2~~$4.4 million, respectively.

~~Certain of the finance~~

Advanced Emissions Solutions, Inc. 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 rightSubsidiaries

Notes to ~~exercise the option.~~Condensed Consolidated Financial Statements

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 commence 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.(Unaudited)

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 carried forward at their carrying values of $8.1 million and $8.2 million, respectively, as of December 31, 2018, and were classified as finance leases as of January 1, 2019. 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 Sheet as of March 31, ~~2019.~~

Finance lease liabilities are subsequently measured by increasing the carrying amount to reflect interest expense on the finance lease liability 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.2020. 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 months ended March 31, ~~2019.~~2020.

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 March 31, ~~2019.~~2020.

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, 2019 for operating leases in effect as 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 costs and impairment. Lease expense from operating leases 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 expense in the period in which the obligation for those payments is incurred. Lease expense for operating leases for the three months ended March 31, 2020 and 2019 was $1.2 million and $1.2 million, respectively, of which $1.0 million and $1.1 million, respectively, is included in Consumables - cost of revenue, exclusive of depreciation and amortization, and $0.2 million and $0.1 million, respectively, is included in General and administrative in the Condensed Consolidated Statement of ~~Operations for the three months ended March 31, 2019.~~

Tax Asset Protection Plan

U.S. federal income tax rules, and Section 382 of the Internal Revenue Code in particular, could substantially limit the use of net operating losses and other tax assets if the Company experiences an "ownership change" (as defined in the Internal Revenue Code). In general, an ownership change occurs if there is a cumulative change in the ownership of the Company by "5 percent stockholders" that exceeds 50 percentage points over a rolling three-year period.

On May 5, 2017, the Board approved the declaration of a dividend of rights to purchase Series B Junior Participating Preferred Stock for each outstanding share of common stock as part of a tax asset protection plan (the ~~"Tax Asset Protection Plan"~~"TAPP") designed to protect the Company’s ability to utilize its net operating losses and tax credits. The ~~Tax Asset Protection Plan~~TAPP is intended to act as a deterrent to any person acquiring beneficial ownership of 4.99% or more of the Company’s outstanding common stock.

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, 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. In estimating income taxes, the Company assesses the relative merits and risks of the appropriate income tax treatment of transactions taking into account statutory, judicial, and regulatory guidance.

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations

The following discussion and analysis of ~~the~~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 ~~2018~~2019 Form 10-K.

Overview

We ~~provide environmental solutions to customers~~are a leader in emissions reductions technologies through consumables that utilize powdered activated carbon (“PAC”) and chemical based technologies, primarily serving the coal-fired power generation ~~municipal water~~ and ~~other industries primarily through emissions and water purification control technologies of our subsidiaries and joint ventures.~~industrial boiler industries. Our proprietary environmental technologies and ~~associated product offerings provide pollutant control solutions to~~specialty chemicals enable ~~coal-fired power generators, industrials and municipal water~~our customers to reduce emissions of mercury and other ~~air~~ pollutants, maximize utilization levels and improve operating efficiencies to ~~assist in~~meet the challenges of existing and potential emissions control regulations. Our products are also used for the purification of water.

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 mercury capture for the coal-fired power plant, industrial and water treatment markets. Carbon Solutions also owns an associated lignite mine that supplies the primary raw material for manufacturing our products.

We operate two segments: Refined Coal ~~(“RC”~~("RC") and Power Generation and Industrials ~~(“PGI”) (f/k/a "Emissions Control" or "EC"~~("PGI"). Our RC segment is comprised of our equity ownership in Tinuum Group, LLC ("Tinuum Group") and Tinuum Services, LLC ("Tinuum Services"), anboth unconsolidated ~~entity that~~entities in which we generate substantial earnings. Tinuum Group provides reduction of mercury and nitrogen oxide ("~~NOX"~~NO_X") 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 ~~("IRC")~~ 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 ~~the~~its revenue from selling or leasing RC facilities to tax equity investors. We also earn royalties for technologies that are licensed 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 provide mercury control and other air and water contaminants control to coal-fired power generators and other industrial companies. Our primary products are produced from lignite coal, which creates ~~activated carbon ("AC").~~AC. From AC, we manufacture various forms of AC that include ~~powdered activated carbon ("PAC")~~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 carbon~~AC 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.

OnDrivers 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 ~~7, 2018 (the "Acquisition Date"), we acquired (the "Carbon Solutions Acquisition"~~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.

Impact of COVID-19

In March 2020, the World Health Organization ("WHO") ~~100%~~declared the novel strain of coronavirus ("COVID-19") a global pandemic. We are designated by the Cybersecurity and Infrastructure Security Agency ("CISA") of the ~~equity interests~~Department of ADA Carbon Solutions, LLC (“Carbon Solutions”). Carbon Solutions is a manufacturer and seller of AC and a leader in mercury capture using PAC for the coal-fired power plant, industrial and water treatment markets. Carbon Solutions also owns an associated lignite mine that supplies the primary raw material for manufacturing powdered activated carbon plant. Carbon Solutions was formed in 2008Homeland Security as a ~~50/50 joint venture by~~critical infrastructure supplier to the ~~Company~~energy sector. Our operations have been deemed essential and, ~~Energy Capital Partners LLC. The Company relinquished its ownership in 2011 as part~~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 ~~a legal settlement agreement as described in~~our personnel, including remote working for those that have the ~~Company's Annual Report on Form 10-K for the fiscal year ended December 31, 2017. The Company acquired Carbon Solutions primarily~~ability to ~~expand the Company's product offerings within the mercury control industry~~do so, sequestered employees at our plant and other ~~complimentary AC markets.~~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 environments for certain employees. We cannot, however, predict the long-term effects on our business, including our financial position or results of operations, if governmental restrictions such as "stay-at-home orders" 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.

Our customers may also be impacted by COVID-19 pandemic as the utilization of energy has declined during “stay-at-home” orders. We cannot predict the long-term impact on our customers and the subsequent impact on our business.

Results of Operations

For the three months ended March 31, ~~2019,~~2020, we recognized net ~~income~~loss of ~~$14.4~~$1.9 million compared to net income of ~~$7.7~~$14.4 million for the three months ended March 31, ~~2018.~~

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.

Comparison of the Three Months Ended March 31, ~~2019~~2020 and ~~2018~~2019

Total Revenue and Cost of Revenue

A summary of the components of our revenues and cost of revenue for the three months ended March 31, ~~2019~~2020 and ~~2018~~2019 is as follows:

Consumables and consumables cost of revenue

For the three months ended March 31, ~~2019 and 2018,~~2020, consumables revenues ~~increased quarter over quarter~~decreased from the comparable period in 2019 primarily due to ~~Carbon Solutions' operations. These operations also increased the total pounds of our consumables sold, and gross margins increased quarter over quarter.~~

~~Consumables cost of revenue was~~lower volumes, which were negatively impacted ~~during~~by low coal-fired power dispatch driven by power generation from sources other than coal. Our gross margin, exclusive of depreciation and amortization, was negative for the three months ended March 31, 2020 as compared to the corresponding quarter in 2019 primarily due to ~~$3.6 million~~the impact of ~~costs recognized as a result of~~lower sales volumes and the step-up in inventory fair value recorded from the Carbon Solutions Acquisition.

Consumables revenue is ~~impacted based on~~affected by electricity demand driven by seasonal weather and related power generation needs, as well as competitor prices related to alternative power generation ~~sources.~~sources such as natural gas. According to data provided by the U.S. Energy Information Administration ("EIA"), for the three months ended March 31, 2020, power generation from coal-fired power dispatch was down approximately 33% compared to the corresponding quarter in 2019. Due to safety actions taken by the Company to provide for continued operation of our manufacturing facilities, we expect that cost of revenue will increase as a result of COVID-19 during the three months ended June 30, 2020.

License royalties, related party

For the three months ended March 31, ~~2019~~2020 and ~~2018,~~2019, there were ~~10.9~~11.9 million tons and ~~7.7~~10.9 million tons, respectively, of RC produced using M-45^TM and M-45-PC^TMtechnologies ("M-45 Technology"), which Tinuum Group licenses from us ("M-45 License"). ~~The increase~~This decrease combined with a lower royalty rate per ton resulted in a decrease in license royalties quarter over quarter. The reduction in the royalty rate per ton was primarily ~~due~~attributable to higher depreciation recognized of approximately $0.8 million on all royalty bearing RC facilities as a result of a reduction in their estimated useful lives as determined by Tinuum Group. Further reducing the rate per ton was a decrease in net lease payments of approximately $0.4 million as a result of Tinuum Group ~~obtaining additional third-party investors for two new RC facilities, one each during the second and fourth quarters of 2018, as well as an additional~~restructuring RC facility ~~during~~contracted leases with its largest customer.

For the three months ended March 31, ~~2019 compared to the same quarter~~2020, we recognized $6.4 million in ~~2018 primarily due to~~equity earnings from Tinuum Group, ~~completing a sale~~which was equal to our proportionate share of ~~an RC facility to a third-party investor during the three months ended March 31, 2019. Under~~ Tinuum Group's revenue recognition policy pursuant to its adoption of ASU 2014-09 (Topic 606), Revenue from Contracts with Customers (“ASU 2014-09”) and ASU 2016-02 as of January 1, 2019, this sale was recognized at a point in time as opposed to over time under Tinuum's legacy revenue recognition policy.

~~During~~net income for the quarter. For the three months ended March 31, 2019, we recognized $19.8 million in equity earnings from Tinuum Group, which was equal to our proportionate share of Tinuum Group's net income of $21.4 million for the quarter less the recovery of the cash distributions in excess of cumulative earnings as of December 31, 2018. During the three months ended March 31, 2018, we recognized $11.1 million in equity earnings from Tinuum Group compared to our proportionate share of Tinuum Group's net income of $12.5 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 March 31, ~~2018 is~~2019 was the result of cumulative distributions received from Tinuum Group being in excess of the carrying value of the investment, and therefore we ~~recognize~~recognized such excess distributions as equity method earnings in the period the distributions ~~occur, as discussed in more detail below.~~occurred.

~~The carrying value of~~For the three months ended March 31, 2020, equity earnings from our ~~investment~~interest in Tinuum Group ~~was $40.2 million as~~were positively impacted by the addition of two new RC facilities during the second half of 2019. However, equity earnings from Tinuum Group for the three months ended March 31, 2020 decreased from the comparable quarter in 2019 primarily from a new RC facility in the first quarter of 2019 that was recognized as ~~our cumulative share~~a point-in-time sale and higher depreciation recognized of ~~pro-rata~~approximately $2.4 million for the three months ended March 31, 2020 on all Tinuum ~~Group's income exceeded the amount of its cumulative cash distributions~~Group RC facilities as a result of a reduction in RC facilities estimated useful lives as determined by Tinuum Group during the second half of 2019. Further contributing to the decrease in equity earnings quarter over quarter was the restructuring of RC facility leases with Tinuum Group's ~~adoption~~largest customer, which decreased lease payments and equity earnings beginning in the three months ended September 30, 2019. We believe the increase in depreciation and decrease in lease payments will negatively impact equity earnings for the remainder of ~~ASU 2014-09 and ASU 2016-02~~2020 as ~~of January 1, 2019,~~well as 2021.

Further, two coal-fired utilities in which we recorded a cumulative adjustment of $28.8 million related to the Company's percentage of Tinuum Group's cumulative effect adjustment that increased the Company's retained earnings as of January 1, 2019. As part of this adjustment, we increased the carrying value of our investment in Tinuum Group ~~by $37.2 million.

As a result of higher depreciation, reduced ~~to zero, as cumulative cash distributions received from Tinuum Group exceeded the Company's pro-rata share~~lease payments and closures of cumulative earnings in Tinuum Group. For quarterly periods during which the ending balance of our investment is greater than zero (e.g., when the cumulative earnings in Tinuum Group exceeds cumulative cash distributions received),two utilities, we ~~recognize~~expect our pro-rata share of Tinuum ~~Group's net income for the period, less any amount necessary~~Group’s earnings and distributions to ~~recover the cumulative earnings short-fall balance as of the end of the immediately preceding quarter. For quarterly periods during which the ending balance of our investment~~be lower in Tinuum Group is zero, we only recognize equity earnings from Tinuum Group to the extent that cash distributions are received from Tinuum Group during the period. The carrying value of our investment in Tinuum Group will be zero when the cumulative amount of distributions received from Tinuum Group exceeds our cumulative pro-rata share of Tinuum Group's net income. See additional information related to our investment balance, equity earnings (losses) and cash distributions in Note 4 of the Condensed Consolidated Financial Statements.

As of March 31, 2019 and 2018, Tinuum Group had 20 and 17 invested RC facilities, respectively, that were generating revenues. There were no 100% retained RC facilities as of March 31, 2019 or March 31, 2018, except for temporary operations of a retained RC facility prior to its lease or sale or our ownership in GWN Manager, LLC.future periods.

Tax Credits and Obligations

Historically, we have earned ~~the following~~ Section 45 tax credits related to the production of RC, ~~that may be available for future benefit:~~

Three Months Ended March 31,

~~The decrease~~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 Tinuum Group's largest customer, which also has an ownership interest in Tinuum Group, substantially all of the tax credits earned from GWN REF were allocated to this customer. As a result, our earned Section 45 tax credits ~~earned during~~for three months ended March 31, 2020 and 2019 were minimal and will likely to continue to be for the remainder of 2020 and 2021.

Interest expense

For the three months ended March 31, 2019 compared to the three months ended March 31, 2018 was due to a decrease in production of RC related to our membership interest in GWN Manager, LLC ("GWN Manager") and Tinuum Group's partial ownership in a single RC facility that is generating tax credits.

The income tax expense recorded for the three months ended March 31, 2020 was comprised of estimated federal income tax expense of $0.3 million and estimated state income tax expense of $0.1 million. The income tax expense recorded for the three months ended March 31, 2019 was comprised of estimated federal income tax expense of $0.8 million and estimated state income tax expense of $0.9 million.

The income tax expense recorded for the three months ended March 31, 2018 was comprised of estimated federal income tax expense of $2.1 million and estimated state income tax expense of $0.5 million. The net decrease in income tax expense quarter over quarter was primarily due to ~~a $4.0~~the pretax loss for the three months ended March 31, 2020 of $1.5 million ~~decrease in the valuation allowance against our deferred tax assets during~~compared to pretax income of $16.1 million for the three months ended March 31, 2019 ~~offset by~~as well as an increase ~~in income tax expense for 2019 based on higher~~

~~forecasted pretax accounting income for 2019 compared to 2018. The decrease~~ in the valuation allowance ~~was primarily due to changes in forecasts~~on deferred tax assets of ~~future taxable income, which included the impact of an additional RC invested facility that was closed during~~$0.9 million for the three months ended March 31, 2020 compared to a decrease in the valuation allowance on deferred tax assets of $4.0 million for the three months ended March 31, 2019. For both quarters, the adjustments to the valuation allowance were based on changes in forecasts as of March 31, 2020 and March 31, 2019, respectively, of future years' taxable income. In addition, income tax expense quarter over quarter was lower from a decrease in state income tax expense of $0.8 million primarily due to lower forecasted pretax income for 2020 compared to 2019.

Non-GAAP Financial Measures

To supplement ~~the Company's~~our 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, Segment EBITDA and RC Segment Adjusted EBITDA. ~~The Company~~We have included non-GAAP measures because management believes that they help to facilitate comparison of operating results between periods. ~~The Company believes~~We 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's~~our results of operations in conjunction with the corresponding GAAP measures.

~~The Company has defined~~We define Consolidated Adjusted EBITDA as net income, adjusted for the impact of the following items that are either non-cash or that ~~the Company does~~we do not consider representative of ~~its~~our 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. Because Consolidated Adjusted EBITDA omits certain non-cash items, ~~the Company believes~~we believe that the measure is less susceptible to variances that affect ~~the Company's~~our operating performance.

We define Segment 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 does~~we do not consider representative of its ongoing operating performance: depreciation, amortization, depletion and accretion and interest expense, net. When used in conjunction with GAAP financial measures, Segment EBITDA is a supplemental measure of operating performance that management believes is a useful measure ~~related the Company's~~for each of our PGI ~~segment~~and RC segment's performance relative to the performance of ~~its~~ competitors as well as performance period over period. Additionally, ~~the Company believes~~we believe the measure is less susceptible to variances that affect its operating performance results.

Business Segments

As of March 31, ~~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 ~~2018~~2019 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:

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 NO_X 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~~.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.

PGI - Our PGI segment ~~primarily~~ includes revenues and related expenses from the sale of consumable products that utilize PAC and 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 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~~.

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~~.

Operations.

For the three months ended March 31, 2020, equity earnings ~~increased~~from our interest in Tinuum Group were positively impacted by the addition of two new RC facilities during the second half of 2019. However, equity earnings from Tinuum Group for the

three months ended March 31, 2020 decreased from the comparable quarter in 2019 primarily ~~due to completing~~from a ~~sale of an~~new RC facility in the first quarter of 2019 that was recognized as a point-in-time sale and higher depreciation recognized of approximately $2.4 million for the three months ended March 31, 2020 on all Tinuum Group RC facilities as described above. Further contributing to ~~a third-party investor during~~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 three months ended September 30, 2019. We believe the increase in depreciation and decrease in lease payments will negatively impact equity earnings for the remainder of 2020 as well as 2021.

For the three months ended March 31, 2020, we recognized $6.4 million in equity earnings from Tinuum Group, which was equal to our proportionate share of Tinuum Group's net income for the quarter. For the three months ended March 31, 2019, ~~which was~~we recognized $19.8 million in ~~Tinuum~~equity earnings ~~during the period.

The difference between our pro-rata share of Tinuum Group's net income and our earnings from our Tinuum ~~Services~~Group equity method investment as reported on the Condensed Consolidated Statements of Operations for the three months ended March 31, 2019 ~~increased~~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 March 31, 2020, earnings from Tinuum Services remained relatively flat compared to the same quarter in ~~2018~~2019 primarily due to ~~an increase~~no change quarter over quarter in the number of operating RC facilities ~~from 16 to 19 for~~in which Tinuum Services provides operating and maintenance services.

~~RC earnings were positively impacted during~~As noted above, for the three months ended March 31, ~~2019~~2020, RC earnings were impacted by ~~an increase~~a decrease in license royalties ~~related to~~earned from Tinuum Group's use of our M-45 License. ~~During~~For the three months ended March 31, ~~2019~~2020 and ~~2018,~~2019, there were ~~10.9~~11.9 million tons and ~~7.7~~10.9 million tons, respectively, of RC produced using the M-45 Technology.

Liquidity and Capital Resources

Overview of Factors Affecting Our Liquidity

During the three months ended March 31, ~~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:

cash on hand;

distributions from Tinuum Group and Tinuum Services; and

royalty payments from Tinuum ~~Group; and~~

~~operations of the PGI segment.~~Group.

Our principal uses of cash during the three months ended March 31, ~~2019~~2020 included:

repurchases of shares of common stock;

payment of dividends;

payment of debt principal and interest; and

our business operating expenses, including federal and state tax payments and cash severance ~~payments; and~~

~~delivering on our existing contracts and customer commitments.~~payments.

Our ability to continue to generate sufficient cash flow required to meet ongoing operational needs and obligations, ~~as well as~~

capital expenditures, future ~~expected~~potential dividend payments and potential future share repurchases depends ~~upon~~on 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 as expansion of~~including expanding our overall PAC business into

additional adjacent markets. Increased distributions from Tinuum Group will likely be dependent upon both preserving existing

contractual relationships and ~~the~~ securing of additional tax equity investors for those Tinuum Group facilities that are currently not operating.

~~Due to the Carbon Solutions Acquisition, we expect that use of liquidity for~~We incur significant recurring capital expenditures ~~will increase in future periods. Carbon Solutions has historically incurred costs~~ for ~~capital expenditures related to its PAC~~our AC manufacturing facility ~~under normal operations and planned outages~~ and for mine development at ~~its~~our lignite mine. ~~Going forward,~~For 2020, we anticipate ~~additional material~~that our capital ~~resources~~expenditures will be ~~needed to maintain or improve capital assets. We have~~lower than 2019 as we do not anticipate having significant planned maintenance as we incurred in 2019.

We expect our liquidity will be impacted from COVID-19 due to anticipated increased operating losses in our ~~manufacturing facility during~~PGI segment from anticipated 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 employees, and overall plant operating inefficiencies. In addition, we also anticipate that Tinuum Group's ability to sell or lease additional RC facilities will be delayed as a result of the ~~three months ended June 30, 2019.~~economic slowdown associated with the COVID-19 pandemic.

In April 2020, we took steps to enhance our short-term liquidity through the Paycheck Protection Program as discussed below.

Tinuum Group and Tinuum Services Distributions

The following table summarizes the cash distributions from our equity method investments that most significantly affected

our consolidated cash flow results for the three months ended March 31, ~~2019~~2020 and ~~2018:~~2019:


	Three Months Ended March 31,				Three Months Ended March 31,
(in thousands)	2019		2018		2020		2019
Tinuum Group	$	16,788	$	11,050	$	13,764	$	16,788
Tinuum Services	2,700		2,400		3,352		2,700
Distributions from equity method investees	$	19,488	$	13,450	$	17,116	$	19,488

Cash distributions from Tinuum Group for the three months ended March 31, 2020 decreased by $3.0 million compared to the three months ended March 31, 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 2019 between Tinuum Group and 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 ~~$200~~$125 to ~~$225~~$150 million, ~~and~~a decrease from the previously reported range of $150 to $175 million. The key drivers in achieving

these future cash flows are based on the following:

20 invested facilities as of March 31, ~~2019~~2020 and inclusive of all net Tinuum cash flows (distributions and license

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 ~~constant.~~consistent with contractual expectations.

~~Future incremental invested RC facilities would positively impact~~Paycheck Protection Program Loan

On April 21, 2020, we entered into a loan (the "PPP Loan") evidenced by a promissory note (the "Promissory Note"), under the Paycheck Protection Program sponsored by the U.S. Small Business Administration ("SBA") through BOK, NA dba Bank of Oklahoma (the "Lender") providing for $3.3 million in proceeds, which amount was funded on April 21, 2020. The PPP Loan was made pursuant to the Coronavirus Aid, Relief, and Economic Security Act (the "CARES Act") and is administered by the SBA.

The Promissory Note 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 Promissory Note 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 the Lender, 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 us, or filing suit and obtaining judgment against us. The Promissory Note principal may be forgiven subject to the terms of the Paycheck Protection Program.

Our business has been 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 ~~expectation of future cash flows.~~manufacturing plant and build-up inventory in order to supply our customers. This resulted in additional costs as the sequestered employees received "hazard pay." We used proceeds from the PPP Loan to fund these additional employment expenses.

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. 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 three months ended March 31, 2020, we made principal payments of $6.0 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 (the "First Amendment") to the Senior Term Loan, which permitted us to enter into the PPP Loan.

Stock Repurchases and Dividends

In November 2018, ~~the~~our Board of Directors (the "Board") authorized us to purchase up to $20.0 million of our outstanding common ~~stock. This~~stock under a stock repurchase program ~~will~~(the "Stock Repurchase Program"), which was to remain in effect until December 31, 2019 unless otherwise modified by the Board. ~~Previously, in December 2017,~~As of November 2019, $2.9 million remained outstanding related to the Stock Repurchase Program. In November 2019, the Board ~~had~~ authorized usan incremental $7.1 million to ~~purchase up to $20.0 million of our outstanding common stock under a separate repurchase program~~the Stock Repurchase Program and provided that ~~was~~it will remain in effect until ~~July~~all amounts are utilized or it is otherwise modified by the Board.

For the three months ended March 31, ~~2018. During~~2020, under the ~~year ended December 31, 2018, under these two stock repurchase programs,~~Stock Repurchase Program, we purchased ~~2,350,422~~20,613 shares of our common stock for cash of ~~$25.3~~$0.2 million, inclusive of commissions and fees.

~~During~~ For the three months ended March 31, 2019, under the Stock Repurchase Program, we purchased 63,876 shares of our common stock for cash of $0.7 million, inclusive of commissions and ~~2018,~~fees. As of March 31, 2020, we had $7.0 million remaining under the Stock Repurchase Program.

For the three months ended March 31, 2020 and 2019, we declared and paid quarterly cash dividends to stockholders of ~~$4.6~~$4.5 million and ~~$5.1~~$4.6 million, ~~respectively, which were paid on March 7, 2019 and March 8, 2018,~~ respectively.

~~As of March 2019, there were no outstanding borrowings under the Line of Credit.~~

On September 30, 2018, ADA, as borrower, we, as guarantor, and the Lender entered into an amendment (the "Twelfth Amendment") to the Line of Credit. The Twelfth Amendment decreased the borrowing availability of the Line of Credit to $5.0 million due to decreased collateral requirements, extended the maturity date of the Line of Credit to September 30, 2020 and permitted the Line of Credit to be used as collateral (in place of restricted cash) for letters of credit ("LC's") up to $5.0 million related to equipment projects and certain other agreements. Under the Twelfth Amendment, there was no minimum balance requirement based on us meeting certain conditions and maintaining minimum trailing twelve-month EBITDA (earnings before interest, taxes, depreciation and amortization), as previously defined in the "Eleventh Amendment" to the Line of Credit, of $24.0 million.

On December 7, 2018, ~~ADA,~~ADA-ES, Inc. ("ADA"), a wholly-owned subsidiary, as borrower, we, as guarantor, and the Lender entered into an amendment to the Line of

~~Credit, which~~ Credit. This amendment provided, among other things, for ADA to be able to enter into the Senior Term Loan as a guarantor so long as

the principal amount of the Senior Term Loan ~~does~~did not exceed $70.0 million. Additionally, the financial covenants in the Line

of Credit were amended and restated to be consistent with the ~~aforementioned~~ Senior Term Loan covenants, including

maintaining a minimum cash balance of $5.0 million.

As of March 31, 2020, we have $5.0 million of borrowing availability and there were no outstanding borrowings under the Line of Credit.

Cash flows from operating activities were positively impacted primarily by the following: (1)~~2019.

Cash flow from financing activities

Cash flows used in financing activities for the three months ended March 31, 2020 decreased by $0.5 million compared to the three months ended March 31, ~~2018. The~~2019 primarily from a decrease was driven primarily by the effect of an increase in our equity investment in Tinuum Group, which resulted in all cash distributions reported as return on investment during the three months ended March 31, 2019. In total, cash distributions increased quarter over quarter ~~due to additional invested RC facilities~~ in ~~the second half of 2018 and first half of 2019.~~

Item 3. Quantitative and Qualitative Disclosures about Market Risk

The information under this Item is not required to be provided by smaller reporting companies.

Item 4. Controls and Procedures

Evaluation of Disclosure Controls and Procedures

As required by Rule 13a‑15(b) under the Securities Exchange Act of 1934, as amended (the "Exchange Act"), we have evaluated, under the supervision of and with the participation of our management, including our principal executive officer and principal financial officer, the effectiveness of the design and operation of our disclosure controls and procedures (as defined in Rules 13a‑15(e) and 15d‑15(e) under the Exchange Act) as of the end of the period covered by this report. Our disclosure controls and procedures are designed to ensure that information required to be disclosed in the reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms. Based upon this evaluation, our principal executive officer and principal financial officer concluded that our disclosure controls and procedures were effective as of March 31, ~~2019.~~2020.

Changes in Internal Control Over Financial Reporting

On December 7, 2018, we acquired Carbon Solutions and excluded their business from our assessment of internal control over financial reporting as of December 31, 2018, as allowed under general guidance issued by the Staff of the Securities and Exchange Commission. Except for the acquisition of Carbon Solutions, thereThere have been no changes in our internal control over financial reporting (as defined in Rules 13a‑15(f) and 15d‑15(f) under the Exchange Act) during the fiscal quarter ended March 31, ~~2019~~2020 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

PART II. OTHER INFORMATION

Item 1. Legal Proceedings

From time to time, we are involved in litigation, claims and other proceedings related to the conduct of our business. ~~Litigation~~Information with respect to this item may be found in Note 8 "Commitments and ~~other disputes are inherently unpredictable and subject~~Contingencies" to ~~substantial uncertainties and unfavorable resolutions could occur. None~~the 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 ~~our 2018~~the 2019 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 currently expect that our operating costs of revenue for the second quarter of fiscal 2020 will be higher than initially anticipated at the beginning of 2020 as a result of reduced plant capacity due to fewer employees physically working at our plant, increased costs associated with those employees continuing to physically work at our plant and disruptions in our supply chain. In addition, 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. Similarly, we anticipate that Tinuum Group's ability to sell or lease additional RC facilities will be delayed due to the economic shutdown.

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, we may be unable to collect receivables from those customers significantly impacted by COVID-19. Also, 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 will be 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 expected, and our personnel costs remain higher than budgeted, our cash needs could increase.

Further, we have 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. We are implementing necessary remediation plans, including backup planning, documentation and training initiatives.
