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 and 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, ~~2020~~2021 (the ~~"2020~~"2021 Form 10-K"). Significant accounting policies disclosed therein have not changed.

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~~weighted-average number of shares of common stock ~~and any participating securities according to dividend and participating rights in undistributed earnings (losses). Pursuant to U.S. GAAP,~~ outstanding during

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.~~

reporting period. Diluted earnings (loss) per share is computed in a manner consistent with that of basic earnings per share, while considering other potentially dilutive securities. For the three and six months ended June 30, 2022 and June 30, 2021, potentially dilutive securities consist of unvested ~~non-participating~~ restricted stock awards ("RSA's")~~, as well as~~ and contingent performance stock units ("PSU's"). ~~For the three~~

Advanced Emissions Solutions, Inc. and ~~six months ended June 30, 2020, potentially dilutive securities consist of both unvested, participating and non-participating RSA's, as well as outstanding options~~Subsidiaries

Notes to ~~purchase common stock ("Stock Options") and PSU's.~~Condensed Consolidated Financial Statements

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. Potentially dilutive securities are excluded from diluted earnings per share when their effect is anti-dilutive. When there is a net loss for a period, all potentially dilutive securities are anti-dilutive and are excluded from the calculation of diluted loss per share for that period.(Unaudited)

The following table sets forth the calculations of basic and diluted (loss) earnings ~~(loss)~~ per share:

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 ~~2020~~2021 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 decline, which could 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~~loss of earnings ~~are significantly affected by equity earnings~~and cash distributions from ~~Tinuum Group. As of June 30, 2021, Tinuum Group has 22 invested RC facilities, of which 8 are leased to a single customer. Both~~both Tinuum Group and Tinuum Services ~~expect~~will continue to commence significantly winding down their operations starting in the third quarter of 2021 due to the expected expiration of the Section 45 tax credit period as of December 31, 2021. During the second quarter of 2021, Tinuum Group ceased operating 1 RC facility, with the remaining RC facilities expected to cease operations during the second half of 2021. The loss of Tinuum Group's customers, reduction in revenue streams as a result of lease renewals and the expiration of Section 45 tax credits will have a significant adverse impact on Tinuum Group's financial position, results of operations and cash flows, which in turn will have a material adverse impact on the Company’s financial position, results of operations and cash flows.

~~Notes~~its cash on hand to ~~Condensed Consolidated Financial Statements~~

provide liquidity over the near and long term. 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. During periods of low natural gas prices, natural gas provides a competitive alternative to coal-fired power generation and therefore, coal consumption may be reduced, which in turn reduces the demand for the Company's products. However, during periods of higher prices for competing power generation sources, ~~the~~there is an increase in coal consumption and thus demand for the Company's products ~~increases due to the increase in coal consumption.~~ also increases.

In addition, coal consumption and demand for the Company's products are ~~also~~ affected by the demand for electricity, which is higher in the warmer and colder months of the year. As a result, the Company's interim period results are subject to seasonal variations whereby its revenues and cost of revenues tend to be higher in its first and third fiscal quarters compared to its second and fourth fiscal quarters. Abnormal temperatures during the summer and winter months may significantly affect coal consumption and impurities within various municipalities' water sources, and thus impact the demand for the Company's products.

Concentration of credit risk

The Company is exposed to concentrations of credit risk primarily related to cash held at financial institutions and accounts receivable. The Company regularly monitors its credit risk to mitigate the possibility of current and future exposures resulting in a loss. Historically, the losses related to credit risk have been immaterial.

The Company holds cash at 2 financial institutions as of June 30, 2022. If a financial institution was unable to perform its obligations, the Company would be at risk regarding the amount of cash and investments in excess of the Federal Deposit Insurance Corporation limits (currently $250 thousand) that would be returned to the Company.

The Company evaluates the creditworthiness of its customers prior to entering into an agreement to sell its products and, as necessary, through the life of the customer relationship.

Reclassifications

Certain balances have been reclassified from the prior year to conform to the current year presentation. Such reclassifications had no effect on the Company’s results of operations or financial position in any of the periods presented.

~~New Accounting Standards~~

~~Adopted~~Notes to Condensed Consolidated Financial Statements

~~In December 2019,~~(Unaudited)

Segments

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 June 30, 2022, the ~~FASB issued ASU 2019-12, Income Taxes (Topic 740) Simplifying~~Company's CODM was the ~~Accounting for Income Taxes ("ASU 2019-12"). The amendments in ASU 2019-12 simplify various aspects related to accounting for income taxes by removing certain exceptions contained in Topic 740~~Company's Chief Executive Officer, and ~~also clarify~~the Company concluded that APT was its 1 reportable segment.

Given the wind-down of Tinuum Group 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,Tinuum Services and ~~early adoption is permitted. The Company adopted ASU 2019-12 effective January 1, 2021 and it did not have a material~~the impact on the Company's financial statements, the Company determined the historical RC segment no longer met the qualitative or quantitative criteria to be considered a reporting segment under U.S. GAAP. As a result, including the method in which the CODM allocates resources, beginning January 1, 2022, the Company determined that it had 1 reportable segment and ~~disclosures.~~therefore has removed its segment disclosures for this Quarterly Report.

~~Not Yet Adopted~~New Accounting Standards

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 form 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, 2022, including interim periods within those years, and must be adopted under a modified retrospective method approach. The Company intends to adopt ASU 2016-13 effective January 1, 2023 and is currently evaluating the provisions of this guidance and assessing the impact on its financial statements and ~~disclosures and~~disclosures. The Company does not believe this standard will have a material impact on its financial statements and disclosures.

Note 2 - Customer Supply Agreement

On September 30, 2020, the Company and Norit Activated Carbon - Americas (f/k/a Cabot Norit Americas, Inc.) ("Norit"), ~~("Cabot")~~ entered into a supply agreement (the "Supply Agreement") pursuant to which the Company agreed to sell and deliver to ~~Cabot,~~Norit, and ~~Cabot~~Norit agreed to purchase and accept from the Company certain lignite-based AC products ("Furnace Products").

~~As part~~ 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 ~~Company and Cabot agreed to additional terms whereby Cabot~~end of any term.

Under the Supply Agreement, Norit also reimburses the Company for certain capital expenditures incurred by the Company that are necessary to manufacture the Furnace ~~Products, and both the Company and Cabot must mutually agree on these~~Products. Reimbursements are comprised ofrevenues earned from capital expenditures ~~in advance of procurement and commissioning. Capital expenditures~~ incurred that will benefit both the Company and ~~Cabot ("Shared~~Norit (referred to as "Shared Capital") ~~are partially reimbursable by Cabot~~ and ~~recognized as~~ revenues ~~based on a formula contained in the Supply Agreement. Revenues~~earned from and reimbursements of Shared Capital are recognized and billable, respectively, beginning on the first day of a half year (January 1 and July 1 of a calendar year) following the placed in service date of a Shared Capital asset(s).

~~Capital~~capital expenditures incurred that will benefit ~~Cabot~~Norit exclusively ~~("Specific~~(referred to as "Specific Capital") are fully reimbursable by Cabot and recognized as revenues based on a formula contained in the Supply Agreement. Revenues earned from Specific Capital are recognized beginning on the first day of a half year following the placed in service date of a Specific Capital asset(s). Reimbursements of Specific Capital 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~~Norit ceases to make purchases under the Supply Agreement, ~~Cabot~~Norit is obligated to pay the balance of any outstanding ~~amounts~~payments for Specific Capital.

~~Revenues earned~~Further, under the terms of the Supply Agreement, Norit was obligated to pay the Reclamation Reimbursement (defined in Note 3 below) to the Company for $10.2 million of the Reclamation Costs (defined in Note 3 below) , inclusive of interest. The Company recorded the Norit Receivable for the Reclamation Reimbursement at its estimated fair value, which was measured using a discounted cash flows valuation model that considered the estimated credit risk associated with the obligor's (Norit's) future performance, which the Company estimated was approximately 1.5%.

On February 25, 2022, the Company received $10.6 million in cash from ~~both Shared Capital and~~Norit (the "Norit Payment") as a result of a change in control provision in the Supply Agreement (the "Change in Control"), which occurred as a result of the sale of Norit by its parent, Cabot Corporation. Under the Change in Control, the Company received from Norit full payment of all amounts outstanding under the Reclamation Reimbursement, payment of all unbilled amounts related to Specific Capital ~~are reported~~for expenditures incurred through February 28, 2022 and payment of $0.8 million related to additional costs due to the third-party operator of Marshall Mine (the "Norit Reclamation Costs"). Under the Reclamation Contract (defined in Note 3 below), the ~~Consumables revenue line item~~Company was obligated to remit payment for the Norit Reclamation Costs to the third-party operator of Marshall Mine, and such payment was remitted in March 2022. The Change in Control did not impact any other provisions of the ~~Statements~~Supply Agreement.

As of ~~Operations.~~February 25, 2022, the carrying value of the Reclamation Reimbursement was $9.0 million, which included the principal balance, adjusted for accretion of interest and payments made to date. Under the Change in Control, the Company received $8.5 million in cash for full payment of the outstanding Reclamation Reimbursement. The Company concluded that the cash

proceeds received represented an early payment of a receivable based on a change in contractual terms and accounted for the difference between the cash proceeds received and the carrying amount of the Reclamation Reimbursement of $0.5 million as a loss for the three months ended March 31, 2022, which is included in the "Other Income (Expense)" line item in the Condensed Consolidated Statement of Operations for the six months ended June 30, 2022.

Also, under the Change in Control, the Company received $1.3 million in advance of revenue to be recognized in future periods related to Specific Capital and recorded this amount as deferred revenue, which is recognized ratably over the remaining contractual term as stipulated in the Supply Agreement.

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 from ~~Cabot~~Norit 100% of the membership interests in Marshall Mine, LLC (the "Marshall Mine ~~Purchase Agreement"~~Acquisition") for a nominal cash purchase price. Marshall Mine, LLC owns a lignite mine located outside of Marshall, Texas (the "Marshall Mine"). The Company concluded that the Marshall Mine did not have any remaining economic reserves and independently determined to immediately commence activities to shutter it. OnAccordingly, on September 30, 2020, the Company and a third party entered into a reclamation contract (the "Reclamation Contract") ~~with a third party that provided a capped cost agreement, subject to certain contingencies, in~~for full reclamation of the ~~amount of approximately $19.7 million plus an obligation to pay certain direct costs estimated~~Marshall Mine, which is expected to be ~~$3.6 million (collectively, the "Reclamation Costs") over the estimated reclamation period of 10 years (the "Reclamation Period").~~completed by 2030. Under the terms of the Supply Agreement, ~~Cabot is~~Norit was obligated to reimburse the Company for $10.2 million ~~of Reclamation Costs~~ (the "Reclamation ~~Reimbursements"~~Reimbursement") for a portion of the total costs incurred under the Reclamation Contract (the "Reclamation Costs"), which ~~are~~was payable semi-annually over 13 years and inclusive of interest. ~~In the event that Cabot has a change~~As discussed in ~~control~~Note 2, on February 25, 2022 as ~~described in the Supply Agreement, all outstanding balances~~part of the ~~Reclamation Reimbursements shall be due and payable~~Change in ~~full. See further discussion of~~Control, Norit fully paid the outstanding amount owed under the Reclamation ~~Costs~~Reimbursement and ~~Reclamation Reimbursements in Note 4.~~has no further liability related to the Marshall Mine.

The Company accounted for the Marshall Mine ~~Purchase Agreement~~Acquisition as an asset acquisition, and it included the acquisition of certain assets ~~that will be consumed~~ and ~~the~~ assumption of certain liabilities ~~that are to be paid in reclamation of the Marshall Mine in addition to~~as well as the incurrence of an obligation for the Reclamation ~~Costs. The Company accounted for~~Costs (the "Marshall Mine ARO"). As of June 30, 2022 and December 31, 2021, the carrying value of the Marshall Mine ~~Purchase Agreement as an asset acquisition.~~ARO was $4.8 million and $6.3 million, respectively.

As the Marshall Mine ~~Purchase Agreement represents~~Acquisition represented a transaction with a customer of net assets acquired and liabilities assumed from ~~Cabot,~~Norit, the Company accounted for the excess of the fair value of liabilities assumed over assets acquired as upfront consideration transferred to a customer, ~~Cabot~~Norit (the "Upfront Customer Consideration"). The amount of the Upfront Customer Consideration was also recognized net of ~~an additional asset recognized in the Marshall Mine Acquisition, which was comprised of a receivable from Cabot (the "Cabot Receivable") for~~ the Reclamation ~~Reimbursements. The Cabot Receivable is further discussed in Note 4.~~

Reimbursement. The total Upfront Customer Consideration is being amortized as a reduction to revenues on a straight-line basis over the expected 15-year contractual period of the Supply Agreement.

~~As part~~ Amortization of the Marshall Mine Purchase Agreement, the Company assumed liabilities, whose fair value exceeded the fair value of assets acquired. A summary of the net assets acquired and liabilities assumed and the additional assets recorded in the Marshall Mine Purchase Agreement as of September 30, 2020 are shown in the table below. The Company completed additional analysis of the assets acquired and liabilities assumed and recorded adjustments as of December 31, 2020 as shown in the table below.

Note 129 - Equity Method Investments

Tinuum Group, LLC

As of June 30, 2022 and December 31, 2021, the Company's ownership interest in Tinuum Group was 42.5%. Tinuum Group supplied technology equipment and technical services at select coal-fired generators, but its primary purpose was to put into operation facilities that produced and sold RC that lowered emissions and also qualified for Section 45 tax credits. The Company concluded that Tinuum Group was a VIE, but the Company did not have the power to direct the activities that most significantly impacted Tinuum Group's economic performance, as the voting partners of Tinuum Group have identical voting rights, equity control interests and board control interests, and therefore power was shared. Accordingly, the Company has accounted for its investment in Tinuum Group under the equity method of accounting since inception.

Note 10 - Stockholders' Equity

Stock Repurchase ~~Programs~~Program

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

~~Quarterly Cash Dividend~~

~~Dividends declared and paid quarterly on all outstanding shares of common stock during the three and six months ended June 30, 2021 and 2020 were as follows:~~

2021 2020
Per share Date paid Per share Date paid
Dividends declared during quarter ended:
March 31 $ 0 N/A $ 0.25 March 10, 2020
June 30 $ 0 N/A $ 0 N/A
$ 0 $ 0.25

A portion of the dividends declared remains accrued subsequent to the payment dates and represents dividends accumulated on nonvested shares of common stock held by employees and directors of the Company that contain forfeitable dividend rights that are not payable until the underlying shares of common stock vest. These amounts are included in both Other current liabilities and Other long-term liabilities on the Condensed Consolidated Balance Sheets as of June 30, 2021 and December 31, 2020.

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~~credits 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 "TAPP") designed to protect the Company’s ability to utilize its net operating losses and tax credits. The 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.

On ~~April 9, 2021,~~March 15, 2022, the Board approved the ~~Fourth~~Fifth Amendment to the TAPP ~~("Fourth~~(the "Fifth Amendment") ~~that~~, which amends the TAPP, as previously amended by the First, Second, Third and ~~Third~~Fourth Amendments that were approved the Board on April 6, 2018, April 5, 2019, April 9, 2020 and April 9, ~~2020,~~2021, respectively. The ~~Fourth~~Fifth Amendment amends the definition of "Final Expiration Date" under the TAPP to extend the duration of the TAPP and makes associated changes in connection therewith. ~~At the Company's 2021 annual meeting of stockholders, the Company's stockholders approved the Fourth Amendment, thus the Final Expiration Date will be the close of business on December 31, 2022.~~

~~Note 13 - Stock-Based Compensation~~

~~The Company grants equity-based awards~~Pursuant to employees, non-employee directors, and consultants that may include, but are not limited to, RSA's, restricted stock units ("RSU's"), performance stock units ("PSU's") and stock options. Stock-based compensation expense related to manufacturing employees and administrative employees is included within the Cost of revenue and Payroll and benefits line items, respectively, in the Condensed Consolidated Statements of Operations.

~~Note 15 - Impairment~~

As of June 30, 2020 and as part of its periodic review of the carrying value of long-lived assets, the Company assessed its long-lived assets for potential impairment. In assessing impairment of its APT segment's and certain other long-lived asset groups, the Company considered factors such as the significant decline in both the APT segment's trailing twelve months revenues and current and future years’ forecasted revenues. These factors were 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.

As of June 30, 2020, the Company completed an undiscounted cash flow analysis of its APT segment's long-lived assets (the "Asset Group"), which are comprised of its manufacturing plant and related 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, 2020, which is reflected as "Impairment of long-lived assets" in the Condensed Consolidated Statements of Operations for the three and six months ended June 30, 2020.

~~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, net~~	~~1,445~~
~~Other long-term assets, net~~	~~5,672~~

~~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 based on cash flows 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 June 30, 2021, the Company determined that there was 0 additional impairment of the Asset Group.~~

loss for this period and the resultant tax benefit was offset by a valuation allowance recorded as of June 30, 2022, as the Company expects to incur pretax loss for the year ended December 31, 2022. The effective rate for the three and six months ended June 30, 2021 was higher ~~than~~from the federal statutory rate primarily from the impact of estimated state income taxes.

The Company assesses ~~the~~a 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 deferred tax 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. 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 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 ("Item 1") of this Quarterly Report and with the audited consolidated financial statements and the related notes of ADES included in the ~~2020~~2021 Form 10-K.

The results of operations discussed in this "Management's Discussion and Analysis of Financial Condition and Results of Operations" are those of ~~Advanced Emissions Solutions, Inc. ("ADES")~~ADES and its consolidated subsidiaries, collectively, the ~~"Company", "we",~~"Company," "we," "our" or ~~"us".~~"us."

Overview

We operate two segments: RC and APT. Our RC segment is comprised of our equity ownership in Tinuum Group and Tinuum Services, both of which are unconsolidated entities in which we generate substantial earnings. Tinuum Group provides reduction of mercury and NOx emissions at select coal-fired power generators through the production and sale of RC that qualifies for Section 45 tax credits under IRC Section 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 are 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. Both Tinuum Group and Tinuum Services expect to commence significantly winding down their operations starting in the third quarter of 2021 due to the expected expiration of the Section 45 tax credit period as of December 31, 2021. During the second quarter of 2021, Tinuum Group ceased operating an RC facility, with the remaining RC facilities expected to cease operations during the second half of 2021. As such, our earnings and distributions from our RC segment will substantially cease as of December 31, 2021.

~~Our APT segment is primarily operated through a wholly-owned subsidiary, Carbon Solutions.~~ We sell consumable products that utilize AC and ~~chemical based~~chemical-based technologies to a broad range of customers, including coal-fired utilities, industrials, water treatment plants, and other diverse markets through ~~the~~a customer supply agreement ~~defined~~described below. Our primary products are comprised of AC, which is produced from ~~lignite coal.~~a variety of carbonaceous raw materials. Our AC products include both powdered activated carbon ("PAC") and granular activated carbon ("GAC"). Our proprietary technologies and associated product offerings provide purification solutions to enable our customers to reduce certain contaminants and pollutants to meet the challenges of existing and potential future regulations. Additionally, we own an associated lignite mine ~~that~~which supplies the primary raw material for the manufacturing of our products.

Through December 31, 2021, we generated substantial earnings from our equity investments in Tinuum Group and Tinuum Services. Both entities ceased operations effective December 31, 2021 as a result of the expiration of a tax credit program under the Section 45 Tax Credit Program. Tinuum Group provided reduction of mercury and nitrogen oxide ("NOx") emissions at select coal-fired power generators through the production and sale of refined coal ("RC") which qualified for tax credits under the Section 45 Tax Credit Program ("Section 45 tax credits"). We also earned royalties for technologies which were 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 operated and maintained the RC facilities under operating and maintenance agreements with Tinuum Group and owners or lessees of the RC facilities. Presently, both Tinuum Group and Tinuum Services continue to wind-down their operations, and we expect to receive final cash distributions from these entities during 2022.

Given the wind-down of Tinuum Group and Tinuum Services and the impact on our financial statements, we determined the historical RC segment no longer met the qualitative or quantitative criteria to be considered a reporting segment under U.S. GAAP. As a result, as well as the method in which the chief operating decision maker allocates resources, beginning January 1, 2022, we determined that we had one reportable segment, and therefore have removed segment disclosures for this Quarterly Report.

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 has been driven primarily from investors who purchase or lease RC facilities that qualify under the Section 45 tax credit period, which is expected to expire no later than December 31, 2021. Operating results in RC are ~~affected by: (1) the ability to lease or operate RC facilities; (2) lease renegotiation or termination; and (3) changes in tonnage~~sales of ~~RC due to changing coal-fired dispatch and electricity power generation sources. As discussed above, earnings and distributions from~~ our ~~RC segment will substantially cease as of December 31, 2021 as Tinuum ceases operations at its RC facilities.~~

~~In the APT segment, demand is driven primarily by~~ consumables-based solutions for coal-fired power generation, ~~and other~~ industrials, municipal water customers and ~~since September 30, 2020, demand from Cabot's customers~~other diverse markets served by Norit, whom we supply through the Supply Agreement discussed below. ~~Operating~~Our operating results ~~in the APT segment has been~~are 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.~~

~~On April 22, 2021, there was an incident at our Red River Plant~~sources and (4) changes in ~~Louisiana ("Plant Incident"), which involved an isolated fire in one of~~demand for contaminant removal within water treatment facilities. During the ~~Red River Plant's coal handling systems. As a result, the Red River Plant was shut down for nine days for repair. As of~~three months ended June 30, ~~2021, the cash flow impact associated with the Plant Incident was $0.2 million~~2022, we have continued to see increases in demand for ~~repairs and $0.7 million in purchased~~our AC products. As such, we continue to purchase inventory to supplement ~~lost production.~~customer demands in excess of our production capacity and to achieve our target inventory levels.

~~Customer~~ Supply Agreement

On September 30, 2020, we and ~~Cabot~~Norit entered into the Supply Agreement pursuant to which we agreed to sell and deliver to ~~Cabot,~~Norit, and ~~Cabot~~Norit agreed to purchase and accept from us, Furnace Products. ~~In addition to~~Under the ~~sale by us and purchase by Cabot of Furnace Products, we and Cabot have agreed to additional terms whereby Cabot will reimburse~~Supply Agreement, Norit reimburses us for certain capital expenditures incurred by us that are necessary to manufacture the Furnace Products.

revenues earned from capital expenditures incurred that will benefit both us and ~~Cabot~~Norit (referred to as "Shared Capital") and revenues earned from capital expenditures incurred that will benefit ~~Cabot~~Norit exclusively (referred to as "Specific Capital").

~~For 2021, we have generated material incremental volume and lowered unit operating costs at~~ In the ~~Red River Plant due~~event that Norit ceases to make purchases under the Supply Agreement, ~~which~~Norit is obligated to pay the balance of any outstanding payments for Specific Capital.

On February 25, 2022, we received $10.6 million in ~~turn has increased our gross margins. Further,~~cash from Norit (the "Norit Payment") as a result of a change in control provision in the Supply Agreement ~~has further expanded our AC products~~(the "Change in Control"), which occurred as a result of the sale of Norit by its parent, Cabot Corporation. Under the Change in Control, we received from Norit full payment of all amounts outstanding under the Reclamation Reimbursement (defined below), payment of all unbilled amounts related to ~~diverse end-markets~~Specific Capital for expenditures

incurred through February 28, 2022 and payment of $0.8 million related to additional Reclamation Costs (the "Norit Reclamation Costs"). Under the Reclamation Contract, we were obligated to remit payment for the Norit Reclamation Costs to the third-party operator of Marshall Mine, and such payment was remitted in March 2022. The Change in Control did not impact any other provisions of the Supply Agreement.

As of February 25, 2022, the carrying value of the Reclamation Reimbursement was $9.0 million and was reflective of the principal balance, adjusted for accretion of interest and payments made to date. Under the Change in Control, we received $8.5 million in cash for full payment of the outstanding Reclamation Reimbursement. We concluded that ~~are outside~~the cash proceeds received represented an early payment of ~~coal-fired power generation.~~a receivable based on a change in contractual terms and accounted for the difference between the cash proceeds received and the carrying amount of the Reclamation Reimbursement of $0.5 million as a loss, which is included within the "Other Income (Expense)" line item in the Condensed Consolidated Statement of Operation for the six months ended June 30, 2022.

Acquisition of Marshall Mine

Marshall Mine ~~LLC owns~~is a lignite mine located outside of Marshall, ~~Texas (the "Marshall Mine").~~Texas. We independently determined to immediately ~~commence activities to~~ shutter the Marshall Mine and ~~have and will continue to incur the associated~~commenced full reclamation ~~costs.~~

~~In conjunction with the execution of the Supply Agreement and the Mine Purchase Agreement, on September 30, 2020, we entered into~~activities under the Reclamation ~~Contract with a third party that provides a capped cost, subject~~Contract. As of June 30, 2022, we have materially completed the dirt work (i.e., contouring, backfilling, etc.) related to ~~certain contingencies, in~~ the amount of approximately $19.7 million plus an obligation to pay certain direct costs estimated to be $3.6 million (collectively, the "Reclamation Costs") over the estimated reclamation period of 10 years. We are accounting for this obligation as an asset retirement obligation under U.S. GAAP ("ARO"). Reclamation Contract.

Under the terms of the Supply Agreement, ~~Cabot is~~Norit was obligated to reimburse us for $10.2 million, inclusive of ~~Reclamation Costs~~interest, over a 13-year term (the "Reclamation ~~Reimbursements"~~Reimbursement")~~, which are payable semi-annually over 13 years~~ for a portion of the Reclamation Costs.

Results of Operations

For the three and six months ended June 30, 2022, we recognized net loss of $0.3 million and $3.4 million, respectively, compared to net income of $16.6 million and $30.3 million for the three and six months ended June 30, 2021, respectively. The most significant factor impacting results period over period was the decrease in equity earnings from Tinuum Group as the ability to generate Section 45 tax credits, the driver for Tinuum Group's operations, ceased as of December 31, 2021.

The following sections provide additional information regarding these comparable 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 current year period to prior year period comparisons of financial results may not be indicative of financial results to be achieved in future periods.

Comparison of the Three Months Ended June 30, 2022 and 2021

Total Revenue and Cost of Revenue

A summary of the components of our revenues and cost of revenue for the three months ended June 30, 2022 and 2021 is as follows:


	Three Months Ended June 30,				Change
(in thousands, except percentages)	2022		2021		($)		(%)
Revenues:
Consumables	$	24,739	$	17,408	$	7,331	42	%
License royalties, related party	—		3,657		(3,657)		(100)	%



Total revenues	$	24,739	$	21,065	$	3,674	17	%
Operating expenses:
Consumables cost of revenue, exclusive of depreciation and amortization	$	19,910	$	14,732	$	5,178	35	%

Consumables and consumables cost of revenue

For the three months ended June 30, 2022, consumables revenues increased from the comparable quarter in 2021 primarily driven by higher product volumes, which comprised $4.6 million of the total change. Product volumes were higher among power generation customers primarily due to higher natural gas prices and higher demand for electricity compared to the same quarter in 2021, which contributed to increased utilization of coal-fired generation and increased demand for our products. Total consumables revenues also increased due to favorable pricing mix of our products by approximately $2.0 million.

Consumables gross margin, exclusive of depreciation and amortization, increased for the three months ended June 30, 2022 compared to the corresponding quarter in 2021 primarily due to the higher product volumes, which resulted in lower fixed costs per pound, as well as increases in the prices of our products. Offsetting these improvements for the three months ended June 30, 2022, consumables gross margin was negatively impacted by higher prices for key raw materials, transportation, including fuel, and other operational costs to produce and deliver our products. Further negatively impacting consumables gross margin was the requirement to purchase inventory due to increased demand for our products and high operating utilization of the Red River Plant. We will continue to need to maintain targeted inventory levels and therefore we expect to continue to purchase inventory at least through the remainder of 2022 as a result of ongoing increased demand for our products and continued high operating utilization at the Red River Plant. We will continue to evaluate the need for additional inventory purchases in subsequent years. In 2023, we expect to complete a turnaround at the Red River Plant and, as a result, we anticipate that our consumables gross margin will be negatively impacted.

We expect that consumables revenues and gross margin will continue to be positively impacted by our product price increase announced in the second quarter of 2022 and our efforts to move our product mix to higher margin products. We anticipate that the product price increases will help offset both the inflation we are experiencing in many of our operating costs and the higher operating costs from purchasing inventory. We also expect that changes in product mix due to the loss of certain power generation customers who are permanently shuttering certain operations as part of scheduled closures will also continue to improve our consumables gross margin.

License royalties, related party

As discussed above, Tinuum Group ceased operations as of December 31, 2021 and as a result for the three months ended June 30, 2022, we did not recognize any revenues from license royalties from Tinuum Group.

Other Operating Expenses

A summary of the components of our operating expenses for the three months ended June 30, 2022 and 2021, exclusive of cost of revenue items (presented above), is as follows:


	Three Months Ended June 30,				Change
(in thousands, except percentages)	2022		2021		($)		(%)
Operating expenses:
Payroll and benefits	$	2,519	$	2,908	$	(389)	(13)	%

Legal and professional fees	1,555		1,431		124		9	%
General and administrative	1,869		1,593		276		17	%

	$	7,565	$	5,894	$	1,671	28	%

Payroll and benefits

Payroll and benefits expenses, which represent costs related to selling, general and administrative personnel, decreased for the three months ended June 30, 2022 compared to the corresponding quarter in 2021 primarily due to a decrease in payroll-related expenses of employees as our headcount decreased quarter over quarter.

Legal and professional fees

Legal and professional fees increased for the three months ended June 30, 2022 compared to the corresponding quarter in 2021 as a result of an increase in costs incurred related to our strategic alternatives review process, and was comprised mostly of consulting fees.

General and administrative

General and administrative expenses increased for the three months ended June 30, 2022 compared to the corresponding quarter in 2021 primarily due to an increase in rent and occupancy expense of $0.2 million and general and administrative expenses, including travel, of $0.1 million.

Depreciation, amortization, depletion and accretion

Depreciation and amortization expense decreased for the three months ended June 30, 2022 compared to the corresponding quarter in 2021 primarily due to higher production volumes compared to sales volumes for the three months ended June 30, 2022, resulting in $0.2 million less absorption of depreciation in inventory. Further driving the decrease was a decrease in accretion expense of $0.2 million related to the Marshall Mine ARO.

Loss (gain) on change in estimate, asset retirement obligation

As of June 30, 2022, we revised our estimate of future obligations ~~due under~~owed for reclamation of the ~~Reclamation Contract.~~Marshall Mine primarily based on a change in the timing of estimated payments for future reclamation requirements. As a result, we increased the Marshall Mine ARO by $34.0 thousand as of June 30, 2022 and recognized a corresponding loss on change in estimate in the Condensed Consolidated Statements of Operations for the three months ended June 30, 2022.

As of June 30, 2021, we revised our estimate of future obligations owed for reclamation of the Marshall Mine primarily based on scope reductions related to future reclamation requirements. As a result, we reduced the Marshall Mine ARO by $1.9 million as of June 30, 2021 and ~~a recorded~~recognized a corresponding gain on change in estimate in the Condensed Consolidated Statements of Operations for the three ~~and six~~ months ended June 30, 2021.

~~Impact of COVID-19~~Other Income (Expense), net

~~In March 2020, the World Health Organization declared COVID-19 a global pandemic. We are designated by CISA~~A summary of the ~~Department~~components of Homeland Security as a critical infrastructure supplier to the energy sector. Our operations have been deemed essential and, therefore, our facilities remained 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. The measures we have taken have resulted in an increase in our personnel costs, operational inefficiencies and the incurrence of incremental costs to allow manufacturing operations to continue.

The duration and scope of the COVID-19 pandemic continues to be uncertain. Many parts of the world are still experiencing high infection rates and the level and timing of COVID-19 vaccine distribution will impact the economic recovery and growth. We cannot 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 CARES Act. The CARES Act provided, among other things, the deferral of payroll tax payments for all payroll taxes incurred through December 31, 2020 and created the Paycheck Protection Program ("PPP")income (expense), which is sponsored and administered by the SBA. In June 2020, the Paycheck Protection Program Flexibility Act of 2020 (the "PPPFA") was signed into law and established the payment dates in the event that amounts borrowed under the PPP are not forgiven. See further discussion below of the loan made to us under the PPP under the section "PPP Loan" under this Item.

~~We elected to defer payments of payroll taxes~~net for the ~~periods allowed under the CARES Act~~three months ended June 30, 2022 and ~~will repay 50% by~~2021 is as follows:

As discussed above, both Tinuum Group and Tinuum Services ceased operations as of December 31, 2021 and ~~50% by December 31, 2022. As of~~as a result for the three months ended June 30, ~~2021, total payroll tax payments deferred under~~2022, we recognized significantly lower earnings from Tinuum Group and Tinuum Services.

Consumables and consumables cost of revenue

For the ~~three~~six months ended June 30, ~~2021,~~2022, consumables revenues increased from the comparable ~~quarter~~period in ~~2020~~2021 primarily driven by higher product volumes, ~~most significantly from products sold under the Supply Agreement,~~ which comprised ~~of $7.4~~approximately $9.5 million of the total revenues, and provided favorable pricing mix of approximately $0.6 million. Negatively impacting revenues quarter over quarter was less favorable product mix of approximately $0.2 million. For the three months ended June 30, 2021, therechange. Product volumes in 2022 were higher ~~than average temperatures as well as an increase~~ in power generation primarily due to higher natural gas prices compared to the prior ~~quarter, both of~~year period, which ~~caused an increase in~~contributed to increased demand for our products.

For the six months ended June 30, 2022, our consumables gross margin was negatively impacted by higher prices for key raw materials, transportation, including fuel, and other operational costs to produce and deliver our products. Further negatively impacting consumables gross margin was an increase during the six months ended June 30, 2022 compared to the prior year period in the amount of purchased inventory to meet customer demand for our products and supplement the higher operating utilization of the Red River Plant. Offsetting these negative impacts were higher product volumes, which resulted in lower fixed ~~cost~~costs per pound, compared to the corresponding quarter. Offsetting higher gross margin from higher product volumes for the three months ended June 30, 2021, was gross margin negatively impacted by routine scheduled maintenance outages planned during the second quarter of 2021 as well as ~~additional costs associated with~~increases in the ~~Plant Incident. The impact~~prices of our products which were mostly in place as of the ~~Plant Incident is expected to continue for the remainder~~beginning of ~~2021 as we continue to purchase inventory due to lost production and increased demand for our products.~~

We expect Consumable revenues and gross margin to be positively impacted by our price increase announced in the second quarter of 2021 along with our efforts to improve customer and product mix. The price increase will also help offset the increase in operating costs.

Consumables revenues 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 June 30, 2021, power generation from coal-fired power dispatch increased approximately 34% compared to the corresponding quarter in 2020.

~~For~~As discussed above, Tinuum Group ceased operations as of December 31, 2021 and as a result, for the ~~three~~six months ended June 30, ~~2021 and 2020, there were 12.8 million tons and 9.2 million tons, respectively, of RC produced using M-45~~TM ~~and M-45-PC~~TM technologies ("M-45 Technology"), which Tinuum Group licenses from us ("M-45 License"). M-45 License royalties increased for the three months ended June 30, 2021 primarily from higher tonnage compared to the three months ended June 30, 2020. This was primarily a result of an increase quarter over quarter in RC facilities that use the M-45 Technology. While tonnage increased quarter over quarter, there was a reduction in the royalty rate per ton primarily attributable to a majority of the RC contracts having fixed lease payments such that increased tonnages2022, we did not ~~result in increased earnings.

~~Depreciation and amortization expense increased for the three months ended June 30, 2021~~2022 compared to the ~~corresponding quarter~~same period in ~~2020~~2021 primarily due to higher production volumes during the ~~three~~six months ended June 30, ~~2021,~~2022, resulting in ~~$0.4~~$0.6 million ~~more~~less absorption of depreciation in inventory. Further driving the ~~increase~~decrease was a decrease in accretion expense of $0.3 million related to the reduction of the Marshall Mine ~~ARO. Offsetting this increase was~~ARO compared to prior year period and a ~~reduction~~decrease in ~~depreciation and~~ amortization expense of ~~$0.6~~$0.2 million related to patents. Offsetting the ~~Impairment Charge recorded~~net decrease period over period was an increase in ~~the second quarter~~depreciation expense of ~~2020 that reduced the carrying value of~~$0.1 million related to an increase in our property, plant and equipment ~~and intangibles.~~as of June 30, 2022 compared to June 30, 2021.

~~Impairment of long-lived assets~~Loss (gain) on change in estimate, asset retirement obligation

As previously discussed, ~~as of June 30, 2020,~~ we recorded a loss on change in estimate of $34.0 thousand primarily based on a change in the ~~Impairment Charge~~timing of ~~$26.1 million,~~estimated payments for future reclamation requirements of the Marshall Mine, which is included in the Condensed Consolidated Statements of Operations for the ~~three~~six months ended June 30, ~~2020.~~

~~Gain on change in estimate, asset retirement obligation~~2022.

As previously discussed, we recorded a gain on change in estimate of $1.9 million related to a reduction in scope of our future reclamation efforts of the Marshall Mine, which is included in the Condensed Consolidated Statements of Operations for the ~~three~~six months ended June 30, 2021.

Earnings from equity method investments		$	3,222	$	39,749

For the ~~three~~six months ended June 30, 2022, we recognized $3.1 million in equity earnings from Tinuum Group compared to our proportionate share of Tinuum Group's net loss of $1.5 million for the period. For the six months ended June 30, 2021, we recognized ~~$19.1~~$35.5 million in equity earnings from Tinuum Group compared to our proportionate share of Tinuum Group's net income of ~~$12.1~~$22.9 million for the ~~quarter. The~~period. For both of these periods, the difference between our pro-rata share of Tinuum Group's net (loss) income and our earnings from Tinuum Group equity method investment as reported on the Condensed Consolidated Statements of Operations is the result of cumulative distributions received from Tinuum Group being in excess of the carrying value of the investment, and therefore we recognize such excess distributions as equity method earnings in the period the distributions occur.

For the ~~three~~six months ended June 30, ~~2020,~~2022, we recognized ~~$6.8~~$0.1 million in equity earnings from Tinuum ~~Group, which was equal to our proportionate share of Tinuum Group's net income for the respective quarter.~~

See further discussion of quarter over quarter changes in Earnings from Equity Investments in "Business Segments" under this Item. Additional information related to equity method investments is included in Note 6 to the Condensed Consolidated Financial Statements included in Part I - Item 1 of this Report.

~~For 2021, we expect to recognize such excess contributions as equity method earnings in the period the distributions occur, limited to the carrying value of the Tinuum Group equity investment.~~

~~Interest expense~~

For the three months ended June 30, 2021, interest expense decreased $0.5 million compared to the three months ended June 30, 2020 primarily due to a reduction in interest expense related to the Senior Term Loan, as the principal balance was reduced from payments of $28.0 million made during the period from June 30, 2020 to June 30, 2021. Further, the Senior Term Loan was paid-off in its entirety as of June 1, 2021. The remaining decrease in interest expense related to reductions in finance lease liabilities and the deferred tax liability associated with Internal Revenue Code section 453A ("Section 453A") during the period from June 30, 2020 to June 30, 2021. Section 453A 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 June 30, 2021, we recorded income tax expense of $4.9 million compared to income tax expense of $0.1 million for the three months ended June 30, 2020. The income tax expense recorded for the three months ended June 30, 2021 was comprised of estimated federal income tax expense of $5.0 million and estimated state income tax benefit of $0.1 million. The income tax expense recorded for the three months ended June 30, 2020 was comprised of estimated federal income tax expense of $0.3 million and estimated state income tax benefit of $0.2 million.

The increase in income tax expense quarter over quarter was primarily due to pretax income for the three months ended June 30, 2021 of $21.5 million compared to a pretax loss for the three months ended June 30, 2020 of $23.7 million.

~~Comparison of the Six Months Ended June 30, 2021 and 2020~~

~~Total Revenue and Cost of Revenue~~

~~A summary of the components of our revenues and cost of revenue for the six months ended June 30, 2021 and 2020 is as follows:~~

Six Months Ended June 30, Change
(in thousands, except percentages) 2021 2020 ($) (%)
Revenues:
Consumables $ 33,007 $ 17,387 $ 15,620 90 %
License royalties, related party 7,723 6,359 1,364 21 %
Total revenues $ 40,730 $ 23,746 $ 16,984 72 %
Operating expenses:
Consumables cost of revenue, exclusive of depreciation and amortization $ 25,774 $ 18,907 $ 6,867 36 %

~~Consumables and consumables cost of revenue~~

For the six months ended June 30, 2021, consumables revenues increased from the comparable period in 2020 primarily driven by higher product volumes, most significantly from products sold under the Supply Agreement, which comprised of approximately $14.5 million of total revenue and favorable price impact of approximately $2.8 million. Negatively impacting consumables revenues period over period was less favorable product mix, which impacted consumables revenue by approximately $1.7 million.

Volumes were positively impacted by seasonal weather and an increase of 4.4% in overall power generation, including an increase in power generation from coal-fired power dispatch, which according to data provided by the EIA, increased approximately 36% for the six months ended June 30, 2021 compared to the corresponding period in 2020.

Our gross margin, exclusive of depreciation and amortization, increased for the six months ended June 30, 2021 compared to the corresponding period in 2020 primarily due to the higher product volumes, which resulted in lower fixed cost per pound compared to the prior year. Offsetting higher gross margin from higher product volumes for the six months ended June 30, 2021, was gross margin negatively impacted by additional costs associated with the Plant Incident.

Consumables cost of revenue was negatively impacted for the six months ended June 30, 2020 due to safety actions taken by us to provide for continued operation of our manufacturing facilities in response to COVID-19.

~~License royalties, related party~~

For the six months ended June 30, 2021 and 2020, there were 27.5 million tons and 21.1 million tons, respectively, of RC produced using the M-45 Technology under the M-45 License. While tonnage increased period over period, there was a reduction in the royalty rate per ton primarily attributable to a majority of the RC contracts having fixed lease payments such that increased tonnages did not result in increased earnings.

Additional information related to revenue concentrations and contributions by class and reportable segment can be found within the segment discussion below and in Note 17 to the Condensed Consolidated Financial Statements.

~~Other Operating Expenses~~

~~A summary of the components of our operating expenses, exclusive of cost of revenue items (presented above), for the six months ended June 30, 2021 and 2020 is as follows:~~

Six Months Ended June 30, Change
(in thousands, except percentages) 2021 2020 ($) (%)

$ 14,187 $ 44,545 $ (30,358) (68) %

* Calculation not meaningful

~~Payroll and benefits~~

Payroll and benefits expenses decreased for the six months ended June 30, 2021 compared to the same period in 2020 primarily due to a decrease in payroll-related expenses of executive and changes in personnel mix. Offsetting these increases were an increase in our headcount and expense related to the Retention Agreements.

~~Legal and professional fees~~

Legal and professional fees increased for the six months ended June 30, 2021 compared to the same period in 2020 primarily due to costs incurred related to our corporate incentives and strategic alternatives, including consulting and legal fees of $0.5 million. Offsetting this increase was a reduction in outsourced IT costs specific to the completion of the integration of Carbon Solutions of $0.4 million.

~~General and administrative~~

General and administrative expenses decreased for the six months ended June 30, 2021 compared to the same period in 2020 primarily due to a decrease in product development expenses of approximately $0.8 million related to the Supply Agreement, a decrease in costs incurred due to the sequestration of certain of our employees at the Red River Plant of approximately $0.3 million and reductions in general and administrative expenses, including recruiting and licenses and fees. Offsetting these decreases was an increase in rent and occupancy expenses of approximately $0.2 million related to property taxes.

~~Depreciation and amortization~~

Depreciation and amortization expense remained relatively flat for the six months ended June 30, 2021 compared to the same period in 2020 due to higher production volumes during the six months ended June 30, 2021, resulting in $0.4 million more absorption of depreciation in inventory. Further driving the increase was accretion expense of $0.6 million related to the Marshall Mine ARO. Offsetting these increases was a reduction in depreciation and amortization expense of $1.0 million related to the Impairment Charge recorded in the second quarter of 2020 that reduced the carrying value of our property, plant, equipment and intangibles.

~~Impairment of long-lived assets~~

As previously discussed, as of June 30, 2020, we recorded the Impairment Charge of $26.1 million, which is included in the Condensed Consolidated Statements of Operations for the six months ended June 30, 2020.

~~Gain on change in estimate, asset retirement obligation~~

~~As of June 30, 2021 and 2020, Tinuum Group had 22 and 20 invested RC facilities, respectively, that were generating revenues.~~

~~For the six months ended June 30, 2021, we recognized $35.5 million in equity earnings from Tinuum Group~~Services compared to our proportionate share of Tinuum ~~Group's~~Services' net ~~income~~loss of ~~$22.9~~$0.1 million for ~~the~~this period. The difference between our pro-rata share of Tinuum ~~Group's~~Services' net ~~income~~loss and our earnings from the Tinuum ~~Group~~Services equity method investment as reported on the Condensed Consolidated Statements of Operations is the result of cumulative distributions received from Tinuum ~~Group~~Services being in excess of the carrying value of the investment, and therefore we recognize such excess distributions as equity method earnings in the period the distributions occur. For the ~~six~~three months ended June 30, ~~2020,~~2021, we recognized ~~$13.2~~$4.3 million in equity earnings from Tinuum ~~Group,~~Services, which was ~~equal to~~ our proportionate share of Tinuum ~~Group's~~Services' net income of $8.5 million for the ~~respective~~ quarter.

See ~~further discussion of period over period changes in Earnings from Equity Investments in "Business Segments" under this Item. Additional~~additional information related to equity method investments is included in Note 69 to the Condensed Consolidated Financial Statements included in Part I - Item 1 of this Report.

Interest expense

For the six months ended June 30, ~~2021,~~2022, interest expense decreased ~~$0.8~~$1.2 million ~~compared~~primarily due to the pay-off of a senior term loan as of June 1, 2021.

Other

On February 25, 2022, we received the Norit Payment as a result of the Change in Control, which occurred as a result of the sale of Norit by its parent, Cabot Corporation. Under the Change in Control, we received from Norit full payment of all amounts outstanding under the Reclamation Reimbursement, payment of all unbilled amounts related to Specific Capital for expenditures incurred through February 28, 2022 and payment of the Norit Reclamation Costs. Under the Reclamation Contract, we are obligated to remit payment for the Norit Reclamation Costs to the third-party operator of Marshall Mine within a specified timeframe, and such payment was remitted in March 2022.

As of February 25, 2022, the Reclamation Reimbursement was $9.0 million and was reflective of the principal balance adjusted for accretion of interest and collection of payments. Under the Change in Control, we received $8.5 million in cash in relation to the outstanding Reclamation Reimbursement. We applied the cash proceeds to the Reclamation Reimbursement and recognized a loss of $0.5 million, which is included in the "Other income (expense)" line item in the Condensed Consolidated Statement of Operations for the six months ended June 30, 2020 primarily due to interest expense incurred in the six months ended June 30, 2021 related to the Senior Term Loan, as the principal balance was reduced from payments of $28.0 million made during the period from June 30, 2020 to June 30, 2021. The remaining decrease in interest expense related to lower 453A interest from a reduction in the deferred balance related to Section 453A during the period from June 30, 2020 to June 30, 2021. 2022.

Income tax expense

For the six months ended June 30, ~~2021,~~2022, we recorded no income tax expense ~~of $9.4 million~~or benefit compared to income tax expense of ~~$0.5~~$9.4 million for the six months ended June 30, ~~2020. The income tax expense recorded~~2021 primarily due to pretax loss for the six months ended June 30, ~~2021 was comprised~~2022 of ~~estimated federal income tax expense of $9.1~~$3.4 million ~~and state income tax expense of $0.3 million. The income tax expense recorded for the six months ended June 30, 2020 was comprised of estimated federal income tax expense of $0.5 million.~~

~~The increase in income tax expense period over period was primarily due~~compared to pretax income for the six months ended June 30, 2021 of $39.8 ~~million compared to~~million. We did not recognize a ~~pretax loss~~tax benefit for the six months ended June 30, ~~2020~~2022 related to the pretax loss for this period, as we recorded a valuation allowance as of ~~$25.2 million.~~June 30, 2022 primarily based on our forecast of pretax loss for the year ended December 31, 2022.

Non-GAAP Financial Measures

To supplement our financial information presented in accordance with U.S. GAAP (or "GAAP"), we ~~are providing~~provide non-GAAP measures of certain financial performance. These non-GAAP measures include Consolidated EBITDA ~~Consolidated Adjusted EBITDA, RC Segment EBITDA, RC Segment Adjusted EBITDA, APT Segment EBITDA~~ and ~~APT Segment~~Consolidated Adjusted EBITDA. We have included these non-GAAP measures because management believes that they help to facilitate period to period comparisons of our operating ~~results. We believe the non-GAAP measures~~results and provide useful information to both management and users of the financial statements by excluding certain expenses, gains and losses ~~that~~which may not be indicative of core operating results and business outlook. Management uses these non-GAAP measures in evaluating the performance of our business.

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 our results of operations in conjunction with the corresponding GAAP measures.

We define Consolidated EBITDA as net income adjusted for the impact of the following items that are either non-cash or that we do not consider representative of our ongoing operating performance: depreciation, amortization, depletion, accretion, amortization of upfront customer consideration, ~~that~~which was recorded ~~as a component of~~in conjunction with the Marshall Mine Acquisition ("Upfront Customer Consideration"), interest expense, net and income ~~tax expense.~~taxes. We define Consolidated Adjusted EBITDA as Consolidated EBITDA reduced by the non-cash impact of equity earnings from equity method investments, ~~and gain on change in estimate, asset retirement obligation and~~ increased by cash distributions from equity method investments and ~~impairment~~loss on early settlement of ~~long-lived assets.~~the Norit Receivable and the change in ARO as a result of a change in estimate. Because Consolidated Adjusted EBITDA omits certain non-cash items, we believe that the measure is less susceptible to variances that affect our operating performance.

We define APT Segment EBITDA (loss) as APT Segment Operating Income (loss) adjusted for the impact of the following items that are either non-cash or that we do not consider representative of our ongoing operating performance: depreciation, amortization, depletion, accretion and interest expense, net and amortization of Upfront Customer Consideration. We define APT Segment Adjusted EBITDA (loss) as APT Segment EBITDA (loss) reduced by gain on settlement and gain on change in estimate, asset retirement obligation and increased by impairment of long-lived assets. There were no additional adjustments made to APT Segment Adjusted EBITDA (loss) for the three and six months ended June 30, 2021.

We define RC Segment EBITDA as RC Segment operating income adjusted for the impact of the following items that are either non-cash or that we do not consider representative of our ongoing operating performance: depreciation, amortization, depletion, accretion and interest expense. We define RC Segment Adjusted EBITDA as 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.

When used in conjunction with GAAP financial measures, we believe these non-GAAP measures are supplemental measures of operating performance ~~that~~which explain our operating performance for our ~~period to period~~period-to-period comparisons and against our competitors' performance. Generally, we believe these non-GAAP measures are less susceptible to variances that affect our operating performance results.

We expect the adjustments to Consolidated ~~Adjusted~~ EBITDA and ~~APT Segment~~Consolidated Adjusted EBITDA in future periods will be generally similar. These non-GAAP measures have limitations as analytical tools and should not be considered in isolation or as a substitute for analyzing our results as reported under GAAP.

~~Business Segments~~

~~As of June~~ 30 2021, we have two reportable segments: (1) RC and (2) APT. 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 2020 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 NO~~X and mercury from the burning of coal. Our equity method investments related to the RC segment primarily include Tinuum Group and Tinuum Services. Segment revenues include our equity method earnings (losses) from our equity method investments and M-45 License royalties earned from Tinuum Group. These earnings are included in 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. Both Tinuum Group and Tinuum Services expect to commence significantly winding down their operations starting in the third quarter of 2021 due to the expected expiration of the Section 45 tax credit period as of December 31, 2021. As such, our earnings and distributions from our RC segment will substantially cease as of December 31, 2021.

2.APT - Our APT segment includes revenues and related expenses from the sale of our AC and chemical products, which are used to purify coal-fired utilities, industrials, water treatment plants, and other markets. For the purification of air and gases, one of the uses of AC is to reduce mercury emissions and other air contaminants, specifically at coal-fired power generators and other industrial companies. These amounts are included within the Consumables and respective 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.

~~The following table presents our operating segment results for the three and six months ended June 30, 2021 and 2020:~~

Earnings from Tinuum Group $ 19,125 $ 6,764 $ 35,487 $ 13,202

Earnings from equity method investments $ 21,437 $ 8,168 $ 39,749 $ 16,441

~~For the three months ended June 30, 2021 and June 30, 2020~~

RC earnings increased primarily due to an increase in equity earnings in Tinuum Group for the three months ended June 30, 2021 compared to the corresponding quarter in 2020, primarily from the addition of three new RC facilities in 2020.

For the three months ended June 30, 2021, earnings from Tinuum Services increased compared to the corresponding quarter in 2020 primarily due to an increase in tonnage quarter over quarter and an increase in the number of operating RC facilities in which Tinuum Services provides operating and maintenance services from 19 to 21.

RC earnings related to M-45 License royalties increased for the three months ended June 30, 2021 compared to the corresponding quarter in 2020 due to higher tonnage quarter over quarter, which was primarily a result of an increase in RC facilities that use the M-45 Technology. While tonnage increased quarter over quarter, there was a reduction in the royalty rate per ton primarily attributable to a majority of the RC contracts having fixed lease payments such that increased tonnages did not result in increased earnings.

~~For the six months ended June 30, 2021 and June 30, 2020~~

RC earnings increased primarily due to an increase in equity earnings in Tinuum Group for the six months ended June 30, 2021 compared to the six months ended June 30, 2020, primarily from the addition of three new RC facilities in 2020. Further, for the six months ended June 30, 2020, we recognized equity earnings from Tinuum Group equal to our proportionate share of Tinuum Group's net income for the period, which was less than cash distributions received for the same period.

For the six months ended June 30, 2021, earnings from Tinuum Services increased compared to the six months ended June 30, 2020 primarily due to an increase in tonnage quarter over quarter and an increase in the number of operating RC facilities in which Tinuum Services provides operating and maintenance services from 19 to 21.

RC earnings related to M-45 License royalties increased for the six months ended June 30, 2021 compared to the six months ended June 30, 2020 due to higher tonnage period over period, which was primarily a result of an increase in RC facilities that use the M-45 Technology. While tonnage increased period over period, there was a reduction in the royalty rate per ton primarily attributable to lower royalty amounts paid related to a facility that was partially retained during 2020 and was producing a higher per-ton royalty amount prior to closure by Tinuum in the second half of 2020.

~~Outlook~~

Both Tinuum Group and Tinuum Services expect to commence significantly winding down their operations starting in the third quarter of 2021 due to the expected expiration of the Section 45 tax credit period as of December 31, 2021. During the second quarter of 2021, Tinuum Group ceased operating an RC facility, with the remaining RC facilities expected to cease operations during the second half of 2021. The loss of equity earnings, distributions and M-45 License royalties beginning in 2022 will have a material adverse effect on our financial condition and consolidated operating results compared to historical periods. Earnings in the RC segment for 2021 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. As a result of the wind-down in both Tinuum Group's and Tinuum Services' operations occurring through the remainder of 2021, we expect our earnings in both entities to decrease in 2021 compared to 2020. However, in 2021, cash distributions should substantially exceed earnings.

~~APT~~

~~Discussion of revenues derived from our APT segment and costs related thereto are included above in our consolidated results.~~

~~For the three months ended June 30, 2021 and June 30, 2020~~

APT segment operating income increased for the three months ended June 30, 2021 compared to the three months ended June 30, 2020 primarily due to the Impairment Charge of $26.1 million recorded for the three months ended June 30, 2020. In addition consumables revenues and associated margins increased for the three months ended June 30, 2021, driven by an increase in volume quarter over quarter, specifically product sold under the Supply Agreement. Our gross margin, exclusive of depreciation and amortization, increased primarily due to the higher volumes that resulted in a lower fixed cost per pound compared to the three months ended June 30, 2020.

~~For the six months ended June 30, 2021 and June 30, 2020~~

APT segment operating income increased for the six months ended June 30, 2021 compared to the six months ended June 30, 2020 primarily due to the Impairment Charge of $26.1 million recorded for the six months ended June 30, 2020. Further, during the six months ended June 30, 2021 consumable revenues and associated margins increased, driven by an increase in volume period over period, specifically products sold under the Supply Agreement.

During the three and six months ended June 30, 2020, we incurred costs of $0.3 million related to sequestration of certain of our employees at the Red River Plant. These costs included hazardous pay, lodging expense and other related costs for 60 days.

~~Outlook~~

Based on current market estimates, we believe that the APT segment will continue to be affected by power generation and the pricing of other sources, including natural gas and renewable energy, as well as weather throughout the U.S. For the remainder of 2021, we expect other power generation sources to have higher prices than in previous quarters, increasing demand for our products. Further, in 2021 and beyond, we expect the Supply Agreement to continue to play a significant role in diversifying our product mix into markets outside of power generation.

Liquidity and Capital Resources

~~Overview of~~Current Resources and Factors Affecting Our Liquidity

For the six months ended June 30, 2021, our liquidity position was positively affected primarily from distributions from Tinuum Group and Tinuum Services, M-45 License royalty payments from Tinuum Group.

As of June 30, ~~2021,~~2022, our principal sources of liquidity ~~include:~~included:

•cash on hand, excluding restricted cash of ~~$16.0~~$10.0 million pledged under ~~the Line of Credit and Surety Agreement requirements;~~

•~~distributions from Tinuum Group and Tinuum Services;~~

•~~M-45 License royalty payments from Tinuum Group;~~

•~~operations of the APT segment;~~a surety bond agreement; and

•~~the Line of Credit.~~our operations.

As of June 30, ~~2021,~~2022, our principal uses of liquidity ~~include:~~included:

•our business operating ~~expenses, including federal~~expenses;

•capital and ~~state tax payments;~~spare parts expenditures;

•payments on our lease obligations; and

•payments of ~~ARO liabilities~~AROs associated with the Five Forks Mine and Marshall Mine.

Due to the expiration of the Section 45 tax credit period as of December 31, 2021 and the resultant wind down of Tinuum Group's and Tinuum Services' operations in 2022, distributions from Tinuum Group and Tinuum Services are no longer a significant source of liquidity.

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 six months ended June 30, ~~2021~~2022 and ~~2020:~~2021:


		Six Months Ended June 30,					Six Months Ended June 30,
(in thousands)	(in thousands)	2021		2020		(in thousands)	2022		2021

Distributions from equity method investees	Distributions from equity method investees	$	43,876	$	32,516	Distributions from equity method investees	$	5,613	$	43,876

Cash distributions from Tinuum ~~Group~~ for the six months ended June 30, ~~2021 increased~~2022 decreased by ~~$11.5~~$38.3 million compared to the six months ended June 30, ~~2020~~2021 primarily due to ~~three RC facilities added in 2020.~~

~~Future cash flows from Tinuum are expected to range from $30 million to $40 million. The key drivers in achieving these future cash flows are based on the following:~~

•~~22 invested facilities as of June 30, 2021 and inclusive of all net Tinuum cash flows (distributions and license~~

~~royalties), offset by estimated federal and state income tax 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 expenditures related to remediation costs;~~

•~~Tax equity lease renewals on invested facilities are not terminated or repriced; and~~

•~~Coal-fired power generation remains consistent with contractual expectations.~~

~~Both~~ Tinuum Group and Tinuum Services ~~expect to commence significantly winding down their~~ceasing material operations ~~starting in the third quarter of 2021 due to the expected expiration of the Section 45 tax credit period~~ as of December 31, 2021. As such, our distributions from our RC segment are expected to decline during the second half of 2021 and will substantially cease as of December 31, 2021, pending final remediation of Tinuum Group’s RC facilities that is expected to occur in 2022.

~~PPP Loan~~

On April 20, 2020, we entered into the PPP Loan under the PPP, evidenced by a promissory note with BOK, providing for $3.3 million in proceeds, which was funded on April 21, 2020. The PPP Loan matures April 21, 2022. The PPP Loan principal may be forgiven subject to the terms of the PPP and approval by the SBA. 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 us, or filing suit and obtaining judgment against us.

In January 2021, we submitted an application to the SBA for forgiveness of the PPP Loan and on July 27, 2021, we received formal notification in the form of a letter dated July 19, 2021 from the Lender that the SBA approved our PPP Loan forgiveness application for our Loan in the amount of $3.3 million (including accrued interest). We will account for the debt forgiveness during its fiscal third quarter of 2021 and will recognize a gain on extinguishment of debt in the amount of $3.3 million in the Consolidated Statements of Operations.

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 the Red River 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 our 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 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. We also paid debt issuance costs of $2.0 million related to the Senior Term Loan. The Senior Term Loan bore interest at a rate equal to 3-month LIBOR (subject to a 1.5% floor) + 4.75% per annum, which was adjusted quarterly to the current 3-month LIBOR rate, and interest was payable quarterly in arrears. The Senior Term Loan was secured by substantially all the assets of the Company, including the cash flows from the Tinuum Entities, but excluding our equity interests in the Tinuum entities.

On June 1, 2021 and prior to the Senior Term Loan's maturity date, we paid-off in its entirety the Senior Term Loan and all remaining accrued interest through this date in the amount of $6.1 million. The Company did not incur any prepayment fees associated with the early pay-off.

~~Line of Credit~~

In September 2013, ADA, as borrower, and us, as guarantor, entered into the Line of Credit with the Lender for an aggregate borrowing amount of $10.0 million, which was secured by certain amounts due to us from certain Tinuum Group RC leases. The Line of Credit has been amended 15 times from the period from December 2, 2013 through June 30, 2021 and included a reduction in the borrowing amount to $5.0 million in September 2018.

On March 23, 2021, we and the Lender entered into an amendment to the Line of Credit (the "Fifteenth Amendment"), which extended the maturity date of the Line of Credit to December 31, 2021 and increased the minimum cash requirement from $5.0 million to $6.0 million. On July 29, 2021, the Company and the Lender entered into the Sixteenth Amendment (the "Sixteenth Amendment") to the Line of Credit. The Sixteenth Amendment amends certain terms and conditions related to collateral securing the Line of Credit.

~~As of June 30, 2021, we have $3.7 million of borrowing availability and no outstanding borrowings under the Line of Credit.~~

~~Stock Repurchases and Dividends~~

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

Under the Stock Repurchase Program, for the three and six months ended June 30, 2021, we did not repurchase any shares. For the three and six months ended June 30, 2020, we purchased zero and 20,613 shares, respectively, of our common stock for cash of zero and $0.2 million, respectively, inclusive of commissions and fees. As of June 30, 2021, we had $7.0 million remaining under the Stock Repurchase Program.

~~For the six months ended June 30, 2021 and 2020, we declared and paid quarterly cash dividends to stockholders of zero and $4.8 million, respectively.~~

~~Liquidity Outlook~~

Our ability to continue to generate sufficient cash flow required to meet ongoing operational needs and obligations, and make potential future dividend payments and share repurchases depends upon several factors, including executing on our contracts and initiatives, receiving M-45 License royalty payments from Tinuum Group and distributions from Tinuum Group and Tinuum Services, increasing our share of the market for APT consumables, including expanding our overall AC business into additional adjacent markets and improving our customer and product mix.

For the remainder of 2021, our primary source of liquidity is expected to be distributions from Tinuum Group and Tinuum Services. These distributions in 2021 will provide sufficient cash on hand to fund operations in 2021 and 2022. For 2021, we expect to spend $11.8 million in capital expenditures compared to $7.1 million incurred in 2020. This increase is primarily the result of product specific capital related to the Supply Agreement, which is estimated to be $3.7 million for the second half of 2021, and routine scheduled maintenance outages, which occurred in the second quarter of 2021. As a result of the Plant Incident, the Red River Plant was shut down for nine days for repair. The cash flow impact associated with the incident was $0.2 million for repairs and $0.7 million in purchased inventory.

During the three months ending June 30, 2021, we entered into the Retention Agreements, which are for the purpose of retaining officers and key employees in order to maintain our current business operations while we pursue and execute on our strategic initiatives. The total amount due at time of payment pursuant to the Retention Agreements is $2.4 million, which will be a future use of cash.

Due to the expiration of the Section 45 tax period as of December 31, 2021 and the resultant wind down of Tinuum Group's and Tinuum Services' operations by the end of 2021, distributions from Tinuum Group will no longer be a material source of liquidity after 2021.

As we look to 2022 and beyond, our primary sources of liquidity are expected to be from cash on hand and through our ongoing operations of our APT segment. We believe the Supply Agreement will provide material incremental volume and lower operating cost efficiencies of our Red River plant, providing additional sources of operating cash flows in the future. Full and partial reimbursements on capital expenditures from Cabot will offset 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. We believe that as reclamation activities occur and the related bonded amounts required under the Surety Agreement are able to be reduced, there may be an opportunity to further reduce the collateral requirement. In 2022 and beyond, our annual capital expenditures are expected to average approximately $5.0 million.

Cash flow from operating activities

Cash flows provided by operating activities for the six months ended June 30, ~~2021~~2022 decreased by ~~$5.9~~$16.4 million compared to the six months ended June 30, ~~2020.~~2021. The ~~net~~ decrease was primarily attributable to net loss of $3.4 million for the six months ended June 30, 2022 compared to net income of $30.3 million for the six months ended June 30, 2021, a decrease in ~~earnings from equity method investees~~Deferred income tax expense of ~~$23.3~~$6.8 million, ~~impairment of long-lived assets of $26.1 million, and~~ a decrease in Distributions from equity method investees, return on investment of ~~$13.4~~$16.8 million ~~for~~and an increase in net working capital of $5.4 million. Offsetting the ~~six months ended June 30, 2021 compared to the six months ended June 30, 2020. Offsetting this~~ net decrease in cash flows provided by operating activities ~~was an increase in net income~~ for the six months ended June 30, ~~2021~~2022 compared to ~~net loss for~~ the six months ended June 30, ~~2020~~2021 were decreases in Earnings from equity method investments of ~~$56.0~~$36.5 million, Other long-term assets, net of $5.7 million, primarily from the Norit Payment in settlement of the Reclamation Reimbursement, and the non-cash gain recognized from the change in estimate of the Marshall Mine ARO of $2.0 million.

Cash flow from investing activities

Cash flows provided by investing activities decreased for the six months ended June 30, ~~2021 increased by $25.1 million~~2022 compared to the six months ended June 30, ~~2020~~2021 by $19.1 million primarily ~~from~~as a result of a decrease in distributions from equity earnings in excess of cumulative ~~earnings.~~

earnings of $21.4 million. Offsetting the net decrease in cash flows provided by investing activities was a decrease in property, plant and equipment additions of $1.7 million.

Cash flow from financing activities

Cash flows used in financing activities for the six months ended June 30, ~~2021 increased by $2.4 million~~2022 compared to the six months ended June 30, ~~2020~~2021 decreased by $16.1 million primarily from ~~an increase~~a decrease in principal loan repayments on ~~the Senior Term Loan of $4.0 million and proceeds received from the PPP Loan during~~a senior term loan.

Material Cash Requirements

For the six months ended June 30, ~~2020 of $3.3 million. Offsetting these increases was a decrease period over period in dividends paid of $4.7 million and repurchases of common shares of $0.2 million.~~

~~Contractual Obligations~~

~~During the six months ended June 30, 2021,~~2022, there were no material changes to our contractual obligations outside of the ordinary course of business from those reported as of December 31, ~~2020, except~~2021. We expect that our cash on hand as of June 30, 2022 will provide sufficient liquidity to fund operations for ~~a reduction~~the next 12 months.

Capital Expenditures

For 2022, we expect to incur $11.0 million in capital expenditures compared to $7.6 million incurred in 2021. This increase is primarily the result of forecasted capital improvements to the Red River Plant of approximately $4.7 million, product specific capital expenditures related to the Supply Agreement of approximately $0.7 million and scheduled maintenance improvements. We expect to fund all capital expenditures for 2022 from cash on hand.

Retention Agreements

On May 4, 2022, the Compensation Committee of the Board and the Board approved the amendment of the retention agreements (the "Retention Agreements"), which had been executed in May 2021, between us and our executive officers and certain other key employees in order to maintain our business operations while we pursue and execute on our strategic initiatives (such amended agreements, the "Amended Retention Agreements"). Under the Amended Retention Agreements, if accepted, the employees will receive (i) 40% of the original amount agreed to in the Retention Agreements ("Retention Pay") in August 2022; (ii) 60% of the Retention Pay on the earliest of (1) the date the employee’s employment is terminated without Cause or for Good Reason (as those terms are defined in the Retention Agreement or the employee’s employment agreement, as applicable), (2) 90 days after a Transaction Date or a Change in Control (as those terms are defined in the Retention Agreement or the employee’s employment agreement, as applicable), or (3) in January 2023; and (iii) an additional lump sum payment, ranging from 10% to 40% of the Retention Pay, will also be paid at the earliest of (1) the date the employee’s employment is terminated without Cause or for Good Reason (as those terms are defined in the Retention Agreement or the employee’s employment agreement, as applicable), (2) 90 days after a Transaction Date or a Change in Control (as those terms are defined in the Retention Agreement or the employee’s employment agreement, as applicable), or (3) in January 2023.

In order to receive the Amended Retention Agreements payments, employees must remain employed at the Company through the dates above. As of June 30, 2022, the total cash payable pursuant to the Amended Retention Agreements is $2.5 million, and we expect to fund these obligations from cash on hand.

Five Forks Mine and Marshall Mine ~~ARO of $1.9 million based on revised estimates from a reduction in scope of the reclamation work.~~

~~Off-Balance Sheet Arrangements~~Obligations

As of June 30, ~~2021,~~2022, we had outstanding surety bonds with regulatory commissions of $24.1 million related to ~~performance requirements under reclamation contracts associated with~~ both the ~~Five Forks~~Marshall Mine and ~~the Marshall~~Five Forks Mine. As of June 30, ~~2021,~~2022, and as required by our surety bond provider, we ~~had~~held restricted cash of $10.0 million ~~securing~~pledged as collateral related to performance requirements required under reclamation contracts for both the ~~Surety Agreement.~~Marshall Mine and Five Forks Mine. We expect that the obligations secured by these surety bonds will be performed in the ordinary course of business and in accordance with the applicable contractual terms. To the extent that the obligations are performed, the related surety bonds should be released and ~~we should not have any continuing obligations.~~collateral requirements reduced. However, in the event any surety bond is called, our indemnity obligations could require us to reimburse the ~~issuer~~surety bond provider.

We intend to fund the remaining portion of the ~~surety bond.~~Reclamation Costs from cash on hand. We believe that as reclamation activities proceed and the amounts required under the MM Surety Bond are able to be reduced, there may be an opportunity to further reduce the collateral requirement.

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 not effective as of June 30, ~~2021.~~2022 due to the material weakness described in Item 9A. "Controls and Procedures" of the Company's Annual Report on Form 10-K for the fiscal year ended December 31, 2021 for the initial application of the adoption of ASC 606 related to the accounting for freight, which was previously immaterial; an inadequate monitoring of interpretative guidance of previously adopted accounting standards; and a lack of a control related to an annual review of policies and procedures for material accounts.

Notwithstanding the material weaknesses, management has concluded that the Condensed Consolidated Financial Statements included in this Quarterly Report present fairly, in all material aspects, the Company’s financial position, results of operations and cash flows for the periods presented in conformity with accounting principles generally accepted in the United States.

Changes in Internal Control Over Financial Reporting

~~There have been no~~Under the applicable SEC rules (Exchange Act Rules 13a-15(f) and 15d-15(f) management is required to evaluate any changes in ~~our~~ internal control over financial reporting ~~(as defined in Rules 13a‑15(f) and 15d‑15(f) under the Exchange Act)~~that occurred during ~~the~~each fiscal quarter ~~ended June 30, 2021~~ that ~~have~~ materially affected, or ~~are~~is reasonably likely to materially affect, our internal control over financial reporting. As discussed in Item 9A. "Controls and Procedures" of the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2021, we identified a material weakness in our internal control over financial reporting detailed above. During the fiscal quarter ended June 30, 2022, we designed and implemented remediation procedures which enhanced existing controls that were ineffective in the prior year and implemented new controls to address the design gaps related to the material weakness. The updates to the internal controls framework include enhanced monitoring of interpretative guidance of previously adopted accounting standards and a periodic review of policies and procedures associated to material accounts. As of June 30, 2022, the updates and additions to controls have been implemented. We believe the controls will bein place for a sufficient period of time to conclude on their effectiveness as of December 31, 2022.

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. Information with respect to this item may be found in Note 117 "Commitments and Contingencies" to the consolidated financial statements included in Item 1 of Part I of this Quarterly Report.

Item 1A. Risk Factors

There are no material updates to our risk factors as disclosed in the ~~2020 Form 10-K except as set forth below. This risk factor should be read together with the risk factors in the 2020~~2021 Form 10-K.

Our inability to meet customer supply requirements due to damage to or insufficient production capacity of our manufacturing facility may have a material adverse effect on our business, results of operations and financial condition.

We own and operate a single activation-based manufacturing plant (the Red River Plant), which is our sole manufacturing plant for producing and selling products to our customers. Our ability to meet customer expectations, manage inventory, complete sales and achieve our objectives for operating efficiencies depends on the full-time operation of the Red River Plant. We cannot replicate our manufacturing methods at another plant due to the limited availability of similar manufacturing plants, the additional costs incurred in supplying raw materials such as lignite to another plant, and the risk of revealing our confidential and proprietary technologies and manufacturing processes.

If the Red River Plant was destroyed or damaged in a significant manner, we would suffer a loss of inventory to supply customers, likely incur additional costs to deliver products to our customers, and disrupt the ordinary course of our business. In addition, if contractual demand exceeds manufacturing capacity, we would jeopardize our ability to fulfill obligations under our contracts, which could, in turn, result in reduced sales, contract penalties or terminations, damage to our customer relationships and could have a material adverse effect on our business. While we have insured the Red River Plan for damage or destruction as well as for losses from business interruptions, there can be no assurance that any insurance coverage will be sufficient to cover any such losses.

Further, a prolonged disruption in our operations due to Red River Plant downtime or having to meet customer requirements that exceed its maximum manufacturing capacity would require us to seek alternative customer supply arrangements, which may not be on attractive terms to us or could lead to delays in distribution of products to our customers, either of which could have a material adverse effect on our business, results of operations and financial condition.
