Note 1 - Basis of Presentation

Nature of Operations

Advanced Emissions Solutions, Inc. ("ADES" or the "Company") is a Delaware corporation with its principal office located in Greenwood Village, Colorado and operations located in Louisiana. The Company is principally engaged in consumable mercury control options including powdered activated carbon ("PAC") and chemical technologies. The Company's proprietary environmental technologies in the power generation and industrial ("PGI") market enable customers to reduce emissions of mercury and other pollutants, maximize utilization levels and improve operating efficiencies to meet the challenges of existing and pending emission control regulations. Through its wholly-owned subsidiary, ADA Carbon Solutions, LLC ("Carbon Solutions"), which the Company acquired on December 7, 2018 (the "Acquisition Date"), the Company manufactures and sells activated carbon ("AC") used in mercury capture for the coal-fired power plant, industrial and water treatment markets. Carbon Solutions also owns an associated lignite mine that supplies the primary raw material for manufacturing PAC.

Through its equity ownership in Tinuum Group, LLC ("Tinuum Group") and Tinuum Services, LLC ("Tinuum Services"), both of which are unconsolidated entities, the Company generates substantial earnings. Tinuum Group provides reduction of mercury and nitrogen oxide ("NOx") emissions at select coal-fired power generators through the production and sale of refined coal ("RC") that qualifies for tax credits under the Internal Revenue Code ("IRC") Section 45 - Production Tax Credit ("Section 45 tax credits"). The Company also earns royalties for technologies that are licensed to Tinuum Group and used at certain RC facilities to enhance combustion and reduced emissions of NOx and mercury from coal burned to generate electrical power. Tinuum Services operates and maintains the RC facilities under operating and maintenance agreements with Tinuum Group and owners or lessees of the RC facilities.

The Company’s sales occur principally in the United States. See Note 15 for additional information regarding the Company's operating segments.

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: Tinuum Group, 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, 2019 (the "2019 Form 10-K"). Significant accounting policies disclosed therein have not changed, except as described later in Note 1.

Earnings (Loss) Per Share

Basic earnings (loss) per share is computed using the two-class method, which is an earnings allocation formula that determines earnings (loss) per share for common stock and any participating securities according to dividend and participating rights in undistributed earnings (losses). The Company's restricted stock awards ("RSA's") granted prior to December 31, 2016 contain non-forfeitable rights to dividends or dividend equivalents and are deemed to be participating securities. RSA's granted subsequent to December 31, 2016 do not contain non-forfeitable rights to dividends and are not deemed to be participating securities.

Under the two-class method, net income for the period is allocated between common stockholders and the holders of the participating securities based on the weighted-average number of common shares outstanding during the period, excluding

Notes to Condensed Consolidated Financial Statements

(Unaudited)

participating, unvested RSA's ("common shares"), and the weighted-average number of participating, unvested RSA's outstanding during the period, respectively. The allocated, undistributed income for the period is then divided by the weighted-average number of common shares and participating, unvested RSA's outstanding during the period to arrive at basic earnings per common share and participating security for the period, respectively. Pursuant to U.S. GAAP, the Company has elected not to separately present basic or diluted earnings per share attributable to participating securities in the Condensed Consolidated Statements of Operations.

Diluted earnings (loss) per share is computed in a manner consistent with that of basic earnings per share, while considering other potentially dilutive securities. Potentially dilutive securities consist of both unvested, participating and non-participating RSA's, as well as outstanding options to purchase common stock ("Stock Options") and contingent performance stock units ("PSU's") (collectively, "Potential dilutive shares"). The dilutive effect, if any, for non-participating RSA's, Stock Options and PSU's is determined using the greater of dilution as calculated under the treasury stock method or the two-class method. Potential dilutive shares are excluded from diluted earnings per share when their effect is anti-dilutive. When there is a net loss for a period, all Potential dilutive shares are anti-dilutive and are excluded from the calculation of diluted loss per share for that period.

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

	Three Months Ended June 30,					Six Months Ended June 30,
(in thousands, except per share amounts)	2020			2019		2020			2019
Net (loss) income	$	(23,814	)	$	8,114	$	(25,707	)	$	22,516
Less: Dividends and undistributed (loss) income allocated to participating securities	(17		)	11		(19		)	31
(Loss) income attributable to common stockholders	$	(23,797	)	$	8,103	$	(25,688	)	$	22,485
Basic weighted-average common shares outstanding	18,014			18,172		17,974			18,219
Add: dilutive effect of equity instruments	—			205		—			193
Diluted weighted-average shares outstanding	18,014			18,377		17,974			18,412
(Loss) earnings per share - basic	$	(1.32	)	$	0.45	$	(1.43	)	$	1.23
(Loss) earnings per share - diluted	$	(1.32	)	$	0.44	$	(1.43	)	$	1.22

For the three and six months ended June 30, 2020 and 2019, RSA's and Stock Options convertible to 0.7 million and 0.7 million, and 0.3 million and 0.3 million shares of common stock, respectively, were outstanding but were not included in the computation of diluted net (loss) income per share because the effect would have been anti-dilutive.

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 2019 Form 10-K except for assumptions regarding impairment of long-lived assets. Actual results could differ from these estimates.

Due to the coronavirus ("COVID-19") pandemic, there has been uncertainty and disruption in the global economy and financial markets. Additionally, due to COVID-19, overall power generation and coal-fired power demand may change, which could also have a material adverse effect on the Company. The Company is not aware of any specific event or circumstance due to COVID-19 that would require an update to its estimate or judgments or a revision of the carrying values of its assets or liabilities through the date of this Quarterly Report. These estimates may change as new events occur and additional information is obtained. Actual results could differ materially from these estimates under different assumptions or conditions.

Risks and Uncertainties

The Company’s earnings are significantly affected by equity earnings it receives from Tinuum Group. As of June 30, 2020, Tinuum Group has 20 invested RC facilities of which 8 are leased to a single customer. A majority of these leases are periodically renewed. Further, the ability to generate Section 45 tax credits related to Tinuum's RC facilities expires in 2021. The loss of a single customer by Tinuum Group or the expiration of Section 45 tax credits would have a significant adverse impact on Tinuum Group's financial position, results of operations and cash flows, which in turn would have a material adverse impact on the Company’s financial position, results of operations and cash flows.

Advanced Emissions Solutions, Inc. and Subsidiaries

Notes to Condensed Consolidated Financial Statements

(Unaudited)

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

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

Not Yet Adopted

In June 2016, the FASB issued ASU 2016-13, Financial Instruments - Credit Losses (Topic 326) Measurement of Credit Losses on Financial Instruments ("ASU 2016-13"). The main objective of ASU 2016-13 is to provide financial statement users with more decision-useful information about the expected credit losses on financial instruments and other commitments to extend credit held by a reporting entity at each reporting date. To achieve this objective, the amendments in ASU 2016-13 replace the incurred loss impairment methodology in current U.S. GAAP with a methodology that reflects expected credit losses and requires consideration of a broader range of reasonable and supportable information to inform credit loss estimates. ASU 2016-13 is effective for "smaller reporting companies" (as defined by the Securities and Exchange Commission) for fiscal years beginning after December 15, 2022, including interim periods within those years, and must be adopted under a modified retrospective method approach. Entities may adopt ASU 2016-13 earlier as of the fiscal years beginning after December 15, 2018, including interim periods within those years. The Company is currently evaluating the provisions of this guidance and assessing its impact on the Company's financial statements and disclosures and does not believe this standard will have a material impact on the Company's financial statements and disclosures.

In December 2019, the FASB issued ASU 2019-12, Income Taxes (Topic 740) Simplifying 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 and also clarifies and amends existing guidance in Topic 740 to improve consistent application. ASU 2019-12 is effective for public business entities beginning after December 15, 2020, including interim periods within those years, and early adoption is permitted. The Company is currently evaluating the provisions of this guidance and assessing its impact on the Company's financial statements and disclosures and does not believe this standard will have a material impact on the Company's financial statements and disclosures.

Note 2 - Impairment

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 Power Generation and Industrials ("PGI") segment's and certain other long-lived asset groups, the Company considered factors such as the significant decline in both PGI’s trailing twelve months revenues and current and future years’ forecasted revenues, which are largely due to the significant drop in coal-fired power dispatch that began in 2019 and is anticipated to continue in the near term largely due to the current and forecasted historical low prices of alternative power generation sources such as natural gas and an increase in supply from other competing energy sources.

The Company completed an undiscounted cash flow analysis of its PGI segment's and certain other 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 of $26.1 million, which is reflected as "Impairment" in the Condensed Consolidated Statements of Operations for the three and six months ended June 30, 2020. The total impairment charge was allocated to the PGI segment and Other in the amounts of $23.2 million and $2.9 million, respectively.

The following table summarizes the allocation of the impairment and write-down of $26.1 million to the Asset Group components during the three months ended 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 using Level 3 inputs under ASC 820 - Fair Value Measurement. The cash flows are those expected to be generated by market participants discounted at the risk-free rate of interest. Because of the continued future uncertainty surrounding the level of coal-fired dispatch, the impact of historically low natural gas prices and other estimates impacting the expected future cash flow, it is reasonably possible that the expected future cash flows may change in the near term and may result in the Company recording additional impairment of the Asset Group.

Note 3 - COVID-19

In response to the COVID-19 outbreak, in March 2020, the federal government passed the Coronavirus Aid, Relief, and Economic Security Act (the "CARES Act"). The CARES Act provided, among other things, the creation of the Paycheck Protection Program ("PPP"), which is sponsored and administered by the U.S. Small Business Administration ("SBA").

On April 20, 2020, the Company entered into a loan (the "PPP Loan") under the PPP, evidenced by a promissory note, with BOK, NA dba Bank of Oklahoma ("BOK") providing for $3.3 million in proceeds, which was funded to the Company on April 21, 2020. The PPP Loan matures April 21, 2022 and provides for 18 monthly payments of principal and interest commencing on November 21, 2020. The interest rate on the PPP Loan is 1.00%. The PPP Loan is unsecured and contains customary events of default relating to, among other things, payment defaults, making materially false and misleading representations to the SBA or BOK, or breaching the terms of the PPP Loan. The occurrence of an event of default may result in the repayment of all amounts outstanding, collection of all amounts owing from the Company, or filing suit and obtaining judgment against the Company. The PPP Loan principal may be forgiven subject to the terms of the PPP and approval by the SBA.

The Company recorded the PPP Loan as a debt obligation under the guidance of ASC 470 - Debt and will accrue interest over the 18-month term of the PPP Loan beginning November 21, 2020.

The CARES Act also provided the deferral of payroll tax payments for all payroll taxes incurred through December 31, 2020. The Company has elected to defer payments of payroll taxes for the periods allowed under the CARES Act and will repay 50% by December 31, 2021 and 50% by December 31, 2022. For the three months ended June 30, 2020, total payroll tax payments deferred under the CARES Act were $0.1 million.

Note 4 - Acquisition

As described in Note 1, on the Acquisition Date, the Company completed the acquisition of Carbon Solutions (the "Carbon Solutions Acquisition") for a total purchase price of $75.0 million (the "Purchase Price"). The fair value of the purchase consideration totaled $66.5 million, less cash acquired of $3.3 million, and the assumption of debt and contractual commitments of $11.8 million. The Company also paid $4.5 million in acquisition-related costs (or transaction costs). The Company funded the cash consideration from cash on hand and the proceeds from the Term Loan and Security Agreement (the "Senior Term Loan") in the principal amount of $70.0 million, as more fully described in Note 7.

Net assets acquired	$	66,446	$	—		$	66,446

Adjustments to the preliminary purchase price allocation primarily related to changes in fair values assigned to property, plant and equipment, intangible assets, mine reclamation liability and the related mine reclamation asset as a result of the final valuation report from the Company's third-party valuation firm issued in May 2019. During the three months ended June 30, 2019 based on new information of facts and circumstances that existed as of the Acquisition Date, the Company revised its estimates used as of the Acquisition Date related to the net realizable value of certain finished goods inventory items as well as values assigned to certain prepaid and accrued expense items.

The following table represents the intangible assets, as adjusted for purchase price adjustments noted above, identified as part of the Carbon Solutions Acquisition:

Note 6 - Equity Method Investments

Tinuum Group, LLC

The Company's ownership interest in Tinuum Group was 42.5% as of June 30, 2020 and December 31, 2019. Tinuum Group supplies technology equipment and technical services at select coal-fired generators, but its primary purpose is to put into operation facilities that produce and sell RC that lower emissions and also qualify for Section 45 tax credits. Tinuum Group has been determined to be a variable interest entity ("VIE"); however, the Company does not have the power to direct the activities that most significantly impact Tinuum Group's economic performance and has therefore accounted for the investment under the equity method of accounting. The Company determined that the voting partners of Tinuum Group have identical voting rights, equity control interests and board control interests, and therefore, concluded that the power to direct the activities that most significantly impact Tinuum Group's economic performance was shared.

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

	Three Months Ended June 30,						Six Months Ended June 30,
(in thousands)	2020			2019			2020			2019
Gross profit	$	6,868		$	38,180		$	11,878		$	79,380

ADES equity earnings from Tinuum Group	$	6,764		$	19,244		$	13,202		$	39,011

For the three and six months ended June 30, 2020 and the three months ended June 30, 2019, the Company recognized its pro-rata share of Tinuum Group's net income available to its members for the respective period. For the six months ended June 30, 2019, the Company recognized its pro-rata share of Tinuum Group's net income available to its members for the period, less the amount necessary to recover the cumulative earnings short-fall balance as of the end of the immediately preceding period, which was December 31, 2018. For the six months ended June 30, 2019, the difference between the Company's proportionate share of Tinuum Group's net income available to members (at its equity interest of 42.5%) and the Company's earnings from its Tinuum Group equity method investment as reported in the Condensed Consolidated Statements of Operations relates to the Company receiving distributions in excess of the carrying value of the equity investment, and therefore recognizing such excess distributions as equity method earnings in the period the distributions occur.

For the three and six months ended June 30, 2020, the Company recognized equity earnings from Tinuum Group of $6.8 million and $13.2 million, respectively. For the three and six months ended June 30, 2019, the Company recognized equity earnings from Tinuum Group of $19.2 million and $39.0 million, respectively.

Note 10 - Commitments and Contingencies

Legal Proceedings

The Company is from time to time subject to, and is presently involved in, various pending or threatened legal actions and proceedings, including those that arise in the ordinary course of its business. Such matters are subject to many uncertainties and outcomes, the financial impacts of which are not predictable with assurance and that may not be known for extended periods of time. The Company records a liability in its consolidated financial statements for costs related to claims, settlements, and judgments where management has assessed that a loss is probable and an amount can be reasonably estimated. There were no significant legal proceedings as of June 30, 2020.

Restricted Cash

As of June 30, 2020 and December 31, 2019, the Company had long-term restricted cash of $5.0 million and $5.0 million, respectively, which primarily consisted of minimum cash balance requirements under the Senior Term Loan.

Other Commitments and Contingencies

The Company has certain limited obligations contingent upon future events in connection with the activities of Tinuum Group. The Company, NexGen Refined Coal, LLC ("NexGen") and 2 entities affiliated with NexGen have provided an affiliate of the Goldman Sachs Group, Inc. with limited guaranties (the "Tinuum Group Party Guaranties") related to certain losses it may suffer as a result of inaccuracies or breach of representations and covenants. The Company also is a party to a contribution agreement with NexGen under which any party called upon to pay on a Tinuum Group Party Guaranty is entitled to receive contributions from the other party equal to 50% of the amount paid. The Company has 0t recorded a liability or expense provision related to this contingent obligation as it believes that it is not probable that a loss will occur with respect to the Tinuum Group Party Guaranties.

Note 11 - Stockholders' Equity

Stock Repurchase Programs

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.

For the three and six months ended June 30, 2020, under the Stock Repurchase Program, the Company purchased 0 and 20,613 shares, respectively, of its common stock for cash of 0 and $0.2 million, respectively, inclusive of commissions and fees.

Quarterly Cash Dividend

Dividends declared and paid quarterly on all outstanding shares of common stock during the three and six months ended June 30, 2020 and 2019 were as follows:

	2020			2019
	Per share		Date paid	Per share		Date paid
Dividends declared during quarter ended:
March 31	$	0.25	March 10, 2020	$	0.25	March 7, 2019
June 30	$	—		$	0.25	June 7, 2019
	$	0.25		$	0.50

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 Sheet as of June 30, 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 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, 2020, the Board approved the Third Amendment to the TAPP ("Third Amendment") that amends the TAPP, as previously amended by the First and Second Amendments that were approved the Board on April 6, 2018 and April 5, 2019, respectively. The Third 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 2020 annual meeting of stockholders, the Company's stockholders approved the Second Amendment, thus the Final Expiration Date will be the close of business on December 31, 2021.

Note 12 - Stock-Based Compensation

The Company grants equity-based awards 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 goods sold and Payroll and benefits line items, respectively, in the Condensed Consolidated Statements of Operations. Stock-based compensation expense related to non-employee directors and consultants is included within the General and administrative line item in the Condensed Consolidated Statements of Operations.

Total unrecognized stock-based compensation expense	$	2,319	2.21

Restricted Stock

Restricted stock is typically granted with vesting terms of three years. The fair value of RSA's and RSU's is determined based on the closing price of the Company’s common stock on the authorization date of the grant multiplied by the number of shares subject to the stock award. Compensation expense for RSA's is generally recognized on a straight-line basis over the entire vesting period. Compensation expense for RSU's is generally recognized on a straight-line basis over the service period of the award.

A summary of RSA activity under the Company's various stock compensation plans for the six months ended June 30, 2020 is presented below:

	Restricted Stock		Weighted-Average Grant Date Fair Value

Forfeited	(3,814	)	$	8.48
Non-vested at June 30, 2020	470,170		$	8.27

Stock Options

Stock options generally vest over three years or upon satisfaction of performance-based conditions and have a contractual limit of five years from the date of grant to exercise. The fair value of stock options granted is determined on the date of grant using the Black-Scholes option pricing model and the related expense is recognized on a straight-line basis over the entire vesting period.

A summary of stock option activity for the six months ended June 30, 2020 is presented below:

Note 14 - Income Taxes

For the three and six months ended June 30, 2020 and 2019, the Company's income tax expense and effective tax rates based on forecasted pretax income were:

	Three Months Ended June 30,						Six Months Ended June 30,
(in thousands, except for rate)	2020			2019			2020			2019
Income tax expense	$	103		$	6,634		$	461		$	8,333
Effective tax rate	—		%	45		%	(2		)%	27		%

The effective rate for the three and six months ended June 30, 2020 was different from the federal statutory rate primarily from an increase in the valuation allowance on deferred tax assets of $4.5 million and $5.4 million, respectively. The increase in the valuation allowance was a result of a reduction in forecasts as of June 30, 2020 of current and future years' taxable income.

The Company assesses the valuation allowance recorded against deferred tax assets at each reporting date. The determination of whether a valuation allowance for deferred tax assets is appropriate requires the evaluation of positive and negative evidence that can be objectively verified. Consideration must be given to all sources of taxable income available to realize the deferred tax asset, including, as applicable, the future reversal of existing temporary differences, future taxable income forecasts exclusive of the reversal of temporary differences and carryforwards, taxable income in carryback years and tax planning strategies. In estimating income taxes, the Company assesses the relative merits and risks of the appropriate income tax treatment of transactions taking into account statutory, judicial, and regulatory guidance.

Note 18 - Subsequent Events

Unless disclosed elsewhere within the notes to the Condensed Consolidated Financial Statements, the following are the significant matters that occurred subsequent to June 30, 2020.

Invested RC Facilities

On July 2, 2020, the Company announced that Tinuum Group sold its 49.9% ownership in a RC project to a new third party investor. The RC facility is located at a coal plant that has historically burned in excess of 2.5 million tons of coal per year. This facility is a royalty bearing facility to the Company. 

Additionally, on July 15, 2020, the Company announced that Tinuum Group completed a lease for an additional RC facility. The RC facility is located at a coal plant that has historically burned in excess of 2.0 million tons of coal per year. With this addition, Tinuum Group has 21 invested facilities in full-time operation.

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

The following discussion and analysis of our financial condition and results of our operations should be read together with the unaudited Condensed Consolidated Financial Statements and notes of Advanced Emissions Solutions, Inc. ("ADES" or the "Company") included elsewhere in Item 1 of Part I of this Quarterly Report and with the audited consolidated financial statements and the related notes of ADES included in the 2019 Form 10-K.

Overview

We are a leader in emissions reductions technologies through consumables that utilize powdered activated carbon ("PAC") and chemical based technologies, primarily serving the coal-fired power generation and industrial boiler industries. Our proprietary environmental technologies and specialty chemicals enable our customers to reduce emissions of mercury and other pollutants, maximize utilization levels and improve operating efficiencies to meet the challenges of existing and potential emissions control regulations. Our products are also used for the purification of water.

Through our wholly-owned subsidiary, ADA Carbon Solutions, LLC ("Carbon Solutions"), which we acquired on December 7, 2018 (the "Acquisition Date"), we manufacture and sell activated carbon ("AC") used in mercury capture for the coal-fired power plant, industrial and water treatment markets. Carbon Solutions also owns an associated lignite mine that supplies the primary raw material for manufacturing our products.

We operate two segments: Refined Coal ("RC") and Power Generation and Industrials ("PGI"). Our RC segment is comprised of our equity ownership in Tinuum Group, LLC ("Tinuum Group") and Tinuum Services, LLC ("Tinuum Services"), both unconsolidated entities in which we generate substantial earnings. Tinuum Group provides reduction of mercury and nitrogen oxide ("NO_X") emissions at select coal-fired power generators through the production and sale of RC that qualifies for tax credits ("Section 45 tax credits") under the Internal Revenue Code Section 45 - Production Tax Credit ("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 used at certain RC facilities to enhance combustion and reduced emissions of NOx and mercury from coal burned to generate electrical power. Tinuum Services operates and maintains the RC facilities under operating and maintenance agreements with Tinuum Group and owners or lessees of the RC facilities.

Our PGI segment includes the sale of products that provide mercury control and other air and water contaminants control to coal-fired power generators and other industrial companies. Our primary products are produced from lignite coal, which creates AC. From AC, we manufacture various forms of AC that include PAC and granular activated carbon ("GAC"). There are three primary consumable products that work in conjunction with the installed equipment at coal-fired utilities to control mercury: PAC, coal additives and scrubber additives. In many cases these three consumable products can be used together or in many circumstances substituted for each other. However, AC is typically the most efficient and effective way to capture mercury and currently accounts for over 50% of the mercury control consumables North American market.

Drivers of Demand and Key Factors Affecting Profitability

Drivers of demand and key factors affecting our profitability differ by segment. In the RC segment, demand is driven primarily by IRC Section 45, which is expected to expire no later than December 31, 2021. Operating results in RC have been influenced by: (1) the ability to sell, lease or operate RC facilities; (2) lease renegotiation or termination; and (3) changes in tonnage of RC due to changing coal-fired dispatch and electricity power generation sources. In the PGI segment, demand is driven primarily by consumables-based solutions for coal-fired power generation and other industrials. Operating results in PGI have been influenced by: (1) changes in our sales volumes; (2) changes in price and product mix; and (3) changes in coal-fired dispatch and electricity power generation sources.

Impairment

As part of our periodic review of the carrying value of long-lived assets, we assessed our long-lived assets for potential impairment as of June 30, 2020. We completed an undiscounted cash flow analysis of our PGI segment's and certain other long-lived asset group (the "Asset Group"), which is comprised of our manufacturing plant and related assets and our lignite mine assets, and estimated the undiscounted cash flows from the Asset Group, which were less than the carrying value of the Asset Group. The decrease in undiscounted cash flows was due to lower volumes impacted by overall lower power generation and an increase in power generation from sources other than coal as a percentage of total generation. Accordingly, we completed an assessment of the Asset Group’s fair value and estimated the fair value of the Asset Group at $32.2 million.

We 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

26

future discounted cash flow model. The cash flows are those expected to be generated by market participants discounted at the risk-free rate of interest. Because of the continued future uncertainty surrounding the level of coal-fired dispatch, the impact of historically low natural gas prices and other estimates impacting the expected future cash flow, it is reasonably possible that the expected future cash flows may change in the near term and may require the recording of additional impairment of the Asset Group.

Impact of COVID-19

In March 2020, the World Health Organization ("WHO") declared the novel strain of coronavirus ("COVID-19") a global pandemic. We are designated by the Cybersecurity and Infrastructure Security Agency ("CISA") of the Department of Homeland Security as a critical infrastructure supplier to the energy sector. Our operations have been deemed essential and, therefore, our facilities remain open and our employees employed. We follow the COVID-19 guidelines from the Centers for Disease Control concerning the health and safety of our personnel, including remote working for those that have the ability to do so, sequestered employees at our plant and other heath safety measures. These measures have resulted in an increase in our personnel costs, operational inefficiencies and the incurrence of incremental costs to allow manufacturing operations to continue; while at the same time we have faced a general downturn in our sales and marketing efforts. The duration of these measures is unknown, may be extended and additional measures may be imposed.

Both of our business segments have continued to operate during the pandemic, and we have taken certain proactive and precautionary steps to ensure the safety of our employees, customers and suppliers, including frequent cleaning and disinfection of workspaces, property, plant and equipment, instituting social distancing measures and mandating remote working environments, where possible, for all employees. We cannot, however, predict the long-term effects on our business, including our financial position or results of operations, if governmental restrictions or other such directives continue for a prolonged period of time and cause a material negative change in power generation demand, materially disrupt our supply chain, substantially increase our operating costs or limit our ability to serve existing customers and seek new customers.

In response to the COVID-19 outbreak, in March 2020, the federal government passed the Coronavirus Aid, Relief, and Economic Security Act (the "CARES Act"). The CARES Act provided, among other things, the deferral of payroll tax payments for all payroll taxes incurred through December 31, 2020. The Company has elected to defer payments of payroll taxes for the periods allowed under the CARES Act and will repay 50% by December 31, 2021 and 50% by December 31, 2022. For the three months ended June 30, 2020, total payroll tax payments deferred under the CARES Act were $0.1 million.

During the three months ended June 30, 2020, we incurred costs of $0.4 million related to sequestration of certain of our employees at our manufacturing plant in Louisiana. These costs included hazard pay, lodging and meal expenses for 30 days.

Our customers may also be impacted by COVID-19 pandemic as the utilization of energy has changed. We cannot predict the long-term impact on our customers and the subsequent impact on our business.

Results of Operations

For the three and six months ended June 30, 2020, we recognized a net loss of $23.8 million and $25.7 million, respectively, compared to net income of $8.1 million and $22.5 million, for the three and six months ended June 30, 2019, respectively.

The operating results for the three and six months ended June 30, 2020 are primarily attributable to a combination of factors, including:

• Continued performance in our RC business segment, principally related to equity earnings and license royalties;

• Performance in our PGI business segment, principally related to Carbon Solutions;

• Impairment recorded related to our PGI segment's and certain other long-lived asset groups; and

• Impacts related to changes in income tax expense.

The following sections provide additional information regarding these comparative periods. For comparability purposes, the following tables set forth our results of operations for the periods presented in the Condensed Consolidated Financial Statements included in Item 1 of this Quarterly Report. The period-to-period comparison of financial results may not be indicative of financial results to be achieved in future periods.

Comparison of the Three Months Ended June 30, 2020 and 2019

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, 2020 and 2019 is as follows:

	Three Months Ended June 30,				Change
(in thousands, except percentages)	2020		2019		($)			(%)
Revenues:
Consumables	$	8,170	$	11,386	$	(3,216	)	(28	)%
License royalties, related party	3,313		4,191		(878		)	(21	)%
Total revenues	$	11,483	$	15,577	$	(4,094	)	(26	)%
Operating expenses:
Consumables cost of revenue, exclusive of depreciation and amortization	$	7,416	$	12,286	$	(4,870	)	(40	)%
Other sales cost of revenue, exclusive of depreciation and amortization	$	—	$	6	$	(6	)	(100	)%

Consumables and consumables cost of revenue

For the three months ended June 30, 2020, consumables revenues decreased from the comparable quarter in 2019 primarily due to lower volumes, which were negatively impacted by lower coal-fired power dispatch driven by a decrease of 5.4% in overall power generation, as well as an increase in power generation from sources other than coal as a percentage of total generation. Our gross margin, exclusive of depreciation and amortization, increased for the three months ended June 30, 2020 compared to the corresponding quarter in 2019 primarily from lower operating costs during the 2020 quarter, driven by increased production volume to ensure inventory levels were adequate to meet customer needs in the event operations were impacted by COVID-19. Consumables revenue is affected by electricity demand driven by seasonal weather and related power generation needs, as well as competitor prices related to alternative power generation sources such as natural gas. According to data provided by the U.S. Energy Information Administration ("EIA"), for the three months ended June 30, 2020, power generation from coal-fired power dispatch was down approximately 26% compared to the corresponding quarter in 2019.

Consumables cost of revenue was negatively impacted for the three months ended June 30, 2019 due to $1.4 million of costs recognized as a result of a step-up in inventory fair value recorded from the acquisition of Carbon Solutions. As of June 30, 2019, the step-up in inventory was fully recognized in cost of revenue.

License royalties, related party

For the three months ended June 30, 2020 and 2019, there were 9.2 million tons and 9.6 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"). This decrease combined with a lower royalty rate per ton resulted in a decrease in license royalties quarter over quarter. The reduction in the royalty rate per ton was primarily attributable to higher depreciation recognized of approximately $0.7 million on all royalty bearing RC facilities as a result of a reduction in their estimated useful lives as determined by Tinuum Group in the second half of 2019. Further reducing the rate per ton was a decrease in net lease payments of approximately $0.3 million as a result of Tinuum Group restructuring RC facility contracted leases with its largest customer in the second half of 2019. As a result of higher depreciation and lower lease payments, we expect that the lower royalty rate per ton will continue for the remainder of 2020 and in 2021.

Additional information related to revenue concentrations and contributions by class and reportable segment can be found within the Business Segments discussion and in Note 15 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 three months ended June 30, 2020 and 2019 is as follows:

	Three Months Ended June 30,				Change
(in thousands, except percentages)	2020		2019		($)			(%)
Operating expenses:
Payroll and benefits	$	3,812	$	2,798	$	1,014		36	%
Legal and professional fees	1,022		1,995		(973		)	(49	)%
General and administrative	2,462		1,995		467			23	%
Depreciation, amortization, depletion and accretion	1,733		757		976			129	%
Impairment of long-lived assets	26,103		—		26,103			*
	$	35,132	$	7,545	$	27,587		366	%

* Calculation not meaningful

Payroll and benefits

Payroll and benefits expenses, which represent costs related to selling, general and administrative personnel, increased for the three months ended June 30, 2020 compared to the corresponding quarter in 2019 primarily due to severance related costs of $1.4 million associated with the resignation of an executive officer. Offsetting this increase was a decrease of approximately $0.3 million related to a decrease in headcount and payroll-related expenses.

Legal and professional fees

Legal and professional fees decreased for the three months ended June 30, 2020 compared to the corresponding quarter in 2019 as a result of cost reductions related to professional fees; primarily consulting and outsourced IT cost specific to the completion of the integration of Carbon Solutions of $0.3 million. The remaining decrease was a result of decreased outsourced shared service costs, including legal and accounting fees.

General and administrative

General and administrative expenses increased for the three months ended June 30, 2020 compared to the corresponding quarter in 2019 primarily due to an increase in product development expenses of approximately $0.4 million and costs incurred due to the sequestration of certain of our employees at our manufacturing plant in Louisiana of approximately $0.3 million. Offsetting this increase was a reduction in general and administrative expenses including travel and Board compensation.

Depreciation, amortization, depletion and accretion

Depreciation and amortization expense increased for the three months ended June 30, 2020 compared to the corresponding quarter in 2019 due to higher production volumes during the three months ended June 30, 2019, resulting in $0.7 million more absorption of depreciation in inventory. Further, the addition of long-lived assets at our manufacturing plant in Louisiana in 2020 contributed approximately $0.2 million of depreciation expense for the three months ended June 30, 2020.

Impairment of long-lived assets

As previously discussed, as June 30, 2020, we recorded an impairment charge of $26.1 million for the three months ended June 30, 2020.

Other Income (Expense), net

A summary of the components of other income (expense), net for the three months ended June 30, 2020 and 2019 is as follows:

	Three Months Ended June 30,						Change
(in thousands, except percentages)	2020			2019			($)			(%)
Other income (expense):
Earnings from equity method investments	$	8,168		$	20,935		$	(12,767	)	(61	)%

Earnings from equity method investments

The following table details the components of our respective equity method investments included within the Earnings from equity method investments line item in the Condensed Consolidated Statements of Operations:

	Three Months Ended June 30,
(in thousands)	2020		2019
Earnings from Tinuum Group	$	6,764	$	19,244
Earnings from Tinuum Services	1,404		1,693
Loss from other	—		(2		)
Earnings from equity method investments	$	8,168	$	20,935

Earnings from equity method investments, and changes related thereto, are impacted by our significant equity method investees: Tinuum Group and Tinuum Services.

For the three months ended June 30, 2020, we recognized $6.8 million in equity earnings from Tinuum Group, which was equal to our proportionate share of Tinuum Group's net income for the quarter. For the three months ended June 30, 2019, we recognized $19.2 million in equity earnings from Tinuum Group, which was equal to our proportionate share of Tinuum Group's net income for the quarter. 

For the three months ended June 30, 2020, equity earnings from our interest in Tinuum Group were positively impacted by the addition of two new RC facilities during the second half of 2019. However, equity earnings from Tinuum Group for the three months ended June 30, 2020 decreased from the comparable period in 2019 primarily from one new RC facility during the three months ended June 30, 2019 that was recognized as a point-in-time sale. Further, equity earnings from Tinuum Group for the three months ended June 30, 2020 decreased from the comparable quarter in 2019 primarily from higher depreciation recognized of approximately $2.5 million for the three months ended June 30, 2020 on all Tinuum Group RC facilities as a result of a reduction in RC facilities' estimated useful lives as determined by Tinuum Group during the second half of 2019. Further contributing to the decrease in equity earnings quarter over quarter was the restructuring of RC facility leases with Tinuum Group's largest customer, which decreased lease payments and equity earnings beginning in the second half of 2019. We believe the increase in depreciation and the decrease in lease payments will negatively impact equity earnings for the remainder of 2020 as well as 2021.

Further, two coal-fired utilities in which Tinuum Group has invested RC facilities announced expected closures in the fourth quarter of 2019 and the associated leases of those facilities terminated during that period. As a result of higher depreciation, reduced lease payments and closures of two utilities, we expect our pro-rata share of Tinuum Group’s earnings and distributions to be lower in future periods.

Equity earnings from our interest in Tinuum Services decreased by $0.3 million for the three months ended June 30, 2020 compared to the three months ended June 30, 2019, and for those quarters, Tinuum Services provided operating and maintenance services to 19 and 20 operating RC facilities, respectively. Tinuum Services derives earnings under fixed-fee arrangements as well as fee arrangements that are based on actual RC production, depending upon the specific RC facility operating and maintenance agreement.

Interest expense

For the three months ended June 30, 2020, interest expense decreased $1.0 million compared to the three months ended June 30, 2019 primarily due to a reduction in interest expense related to a senior term loan (the "Senior Term Loan"), as the principal balance was reduced from payments of $26.0 million quarter over quarter. The remaining decrease in interest expense related to a reduction in the deferred balance related to Internal Revenue Code section 453A ("453A"), which requires taxpayers to pay an interest charge ("453A interest") on the portion of the tax liability that is deferred under the installment method for tax purposes. 

Income tax expense

For the three months ended June 30, 2020, we recorded income tax expense of $0.1 million compared to income tax expense of $6.6 million for the three months ended June 30, 2019. 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 income tax expense recorded for the three months ended June 30, 2019 was comprised of estimated federal income tax expense of $6.2 million and estimated state income tax expense of $0.4 million.

30

The decrease in income tax expense quarter over quarter was primarily due to a pretax loss for the three months ended June 30, 2020 of $23.7 million compared to pretax income of $14.7 million for the three months ended June 30, 2019 as well as an increase in the valuation allowance on deferred tax assets of $4.5 million for the three months ended June 30, 2020 compared to an increase in the valuation allowance on deferred tax assets of $4.8 million for the three months ended June 30, 2019. For both quarters, the adjustments to the valuation allowance were based on changes in forecasts as of June 30, 2020 and June 30, 2019, respectively, of future years' taxable income.

Comparison of the Six Months Ended June 30, 2020 and 2019

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, 2020 and 2019 is as follows:

	Six Months Ended June 30,				Change
(in thousands, except percentages)	2020		2019		($)			(%)
Revenues:
Consumables	$	17,387	$	26,495	$	(9,108	)	(34	)%
License royalties, related party	6,359		8,411		(2,052		)	(24	)%
Total revenues	$	23,746	$	34,906	$	(11,160	)	(32	)%
Operating expenses:
Consumables cost of revenue, exclusive of depreciation and amortization	$	18,907	$	26,394	$	(7,487	)	(28	)%
Other sales cost of revenue, exclusive of depreciation and amortization	$	—	$	6	$	(6	)	(100	)%

Consumables and consumables cost of revenue

For the six months ended June 30, 2020, consumables revenues decreased from the comparable period in 2019 primarily due to lower volumes, which were negatively impacted by lower coal-fired power dispatch driven by a decrease of 5.0% in overall power generation as well as an increase in power generation from sources other than coal as a percentage of total generation. Our gross margin, exclusive of depreciation and amortization, was negative for the six months ended June 30, 2020 compared to the corresponding period in 2019 primarily due to the impact of lower sales volumes and the high fixed cost operating structure. Consumables revenue is affected by electricity demand driven by seasonal weather and related power generation needs, as well as competitor prices related to alternative power generation sources such as natural gas. According to data provided by the EIA, for the six months ended June 30, 2020, power generation from coal-fired power dispatch was down approximately 30% compared to the corresponding period in 2019. Due to safety actions taken by the Company to provide for continued operation of our manufacturing facilities in response to COVID-19, cost of revenue increased for the six months ended June 30, 2020.

Consumables cost of revenue was negatively impacted during the six months ended June 30, 2019 due to $5.0 million of costs recognized as a result of the step-up in inventory fair value recorded from the acquisition of Carbon Solutions. As of June 30, 2019, the step-up in inventory was fully recognized in cost of revenue.

License royalties, related party

For the six months ended June 30, 2020 and 2019, there were 21.1 million tons and 20.5 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 higher depreciation recognized of approximately $1.5 million on all royalty bearing RC facilities as a result of a reduction in their estimated useful lives as determined by Tinuum Group in the second half of 2019. Further reducing the rate per ton was a decrease in net lease payments of approximately $0.7 million as a result of Tinuum Group restructuring RC facility contracted leases with its largest customer in the second half of 2019. As a result of higher depreciation and lower lease payments, we expect that the lower royalty rate per ton will continue in 2020 and 2021.

Additional information related to revenue concentrations and contributions by class and reportable segment can be found within the segment discussion below and in Note 15 to the Condensed Consolidated Financial Statements.

	$	44,545	$	16,321	$	28,224		173	%

* Calculation not meaningful

Payroll and benefits

Payroll and benefits expenses increased for the six months ended June 30, 2020 compared to the same period in 2019 primarily due to severance related costs $1.4 million associated with the resignation of an executive officer, offset by a decrease in headcount.

Legal and professional fees

Legal and professional fees expenses decreased for the six months ended June 30, 2020 compared to the same period in 2019 primarily due to decreased outsourced shared service costs, including legal, general consulting and audit fees, of approximately $1.3 million. Offsetting these decreases was an increase in outsourced IT costs specific to the completion of the integration of Carbon Solutions of $0.2 million.

General and administrative

General and administrative expenses increased for the six months ended June 30, 2020 compared to the same period in 2019 primarily due to an increase in product development expenses of approximately $0.7 million and costs incurred due to the sequestration of certain of our employees at our manufacturing plant in Louisiana of approximately $0.3 million. Offsetting this increase was a reduction in general and administrative expenses including travel and Board compensation.

Depreciation and amortization

Depreciation and amortization expense increased for the six months ended June 30, 2020 compared to the same period in 2019 due to higher volumes during the six months ended June 30, 2019 causing $0.6 million more absorption of depreciation in inventory. Further, the addition of long-lived assets at our manufacturing plant in Louisiana in 2020 contributed approximately $0.3 million of depreciation expense for the three months ended June 30, 2020.

Impairment of long-lived assets

As discussed above, as of June 30, 2020, and we recorded an impairment charge of $26.1 million for the six months ended June 30, 2020.

Other Income (Expense), net

A summary of the components of our other income (expense), net for the six months ended June 30, 2020 and 2019 is as follows:

Earnings from equity method investments

The following table details the components of our respective equity method investments included within the Earnings from equity method investments line item on the Condensed Consolidated Statements of Operations:

	Six Months Ended June 30,
(in thousands)	2020			2019
Earnings from Tinuum Group	$	13,202		$	39,011
Earnings from Tinuum Services	3,242			3,615
Loss from other	(3		)	(1		)
Earnings from equity method investments	$	16,441		$	42,625

For the six months ended June 30, 2020, we recognized $13.2 million in equity earnings from Tinuum Group, which was equal to our proportionate share of Tinuum Group's net income for the period. For the six months ended June 30, 2019, we recognized $39.0 million in equity earnings from Tinuum Group, which was equal to our proportionate share of Tinuum Group's net income of $40.7 million for the period less the recovery of the cash distributions in excess of the cumulative earnings as of December 31, 2018. The difference between our pro-rata share of Tinuum Group's net income and our earnings from our Tinuum Group equity method investment as reported on the Condensed Consolidated Statements of Operations for the six months ended June 30, 2019 was the result of cumulative distributions received from Tinuum Group being in excess of the carrying value of the investment, and therefore we recognized such excess distributions as equity method earnings in the period the distributions occurred.

For the six months ended June 30, 2020, equity earnings from our interest in Tinuum Group were positively impacted by the addition of two new RC facilities during the second half of 2019. However, equity earnings from Tinuum Group for the six months ended June 30, 2020 decreased from the comparable period in 2019 primarily from two new RC facilities during the six months ended June 30, 2019 that were recognized as point-in-time sales. Further, the decrease in equity earnings was due to higher depreciation recognized of approximately $4.9 million for the six months ended June 30, 2020 on all Tinuum Group RC facilities as a result of a reduction in RC facilities' estimated useful lives as determined by Tinuum Group during the second half of 2019. Further contributing to the decrease in equity earnings for the six months ended June 30, 2020 compared to the six months ended June 30, 2019 was the restructuring of RC facility leases with Tinuum Group's largest customer, which decreased lease payments and equity earnings beginning in the second half of 2019. Furthermore, two coal-fired utilities in which Tinuum Group has invested RC facilities announced expected closures in the fourth quarter of 2019 and the associated leases of those facilities terminated during that period. As a result of higher depreciation, reduced lease payments and closures of two utilities, we expect our pro-rata share of Tinuum Group’s earnings will be lower for the remainder of 2020 as well as 2021.

As of June 30, 2020 and 2019, Tinuum Group had 20 and 21 invested RC facilities, respectively, that were generating revenues.

Equity earnings from our interest in Tinuum Services decreased during the six months ended June 30, 2020 compared to the six months ended June 30, 2019. During the six months ended June 30, 2020 and 2019, Tinuum Services provided operating and maintenance services to 19 and 20 operating RC facilities, respectively, which was the primary driver in the decrease in equity earnings period over period. Tinuum Services derives earnings under fixed-fee arrangements as well as fee arrangements that are based on actual RC production, depending upon the specific RC facility operating and maintenance agreement.

Interest expense

For the six months ended June 30, 2020, interest expense decreased $1.9 million compared to the six months ended June 30, 2019 primarily due to interest expense incurred in the six months ended June 30, 2020 related to the Senior Term Loan, as the principal balance was reduced from payments of $26.0 million period over period. The remaining decrease in interest expense related to lower 453A interest from a reduction in the deferred balance related to 453A. 

Income tax expense

For the six months ended June 30, 2020, we recorded income tax expense of $0.5 million compared to income tax expense of $8.3 million for the six months ended June 30, 2019. 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 income tax expense recorded for the six months ended June 30, 2019 was comprised of estimated federal income tax expense of $7.0 million and estimated state income tax expense of $1.3 million.

33

The decrease in income tax expense period over period was primarily due to a pretax loss for the six months ended June 30, 2020 of $25.2 million compared to pretax income for the six months ended June 30, 2019 of $30.8 million. Offsetting the decrease in income tax expense period over period was an increase in the valuation allowance on deferred tax assets of $5.4 million for the six months ended June 30, 2020 compared to an increase in the valuation allowance of $0.8 million for the six months ended June 30, 2019 based on changes in forecasts of future years' taxable income as of June 30, 2020 and June 30, 2019, respectively.

Non-GAAP Financial Measures

To supplement our financial information presented in accordance with accounting principles generally accepted in the U.S. ("GAAP"), we are providing non-GAAP measures of certain financial performance. These non-GAAP measures include Consolidated Adjusted EBITDA, PGI Segment EBITDA and RC Segment Adjusted EBITDA. We have included non-GAAP measures because management believes that they help to facilitate comparison of operating results between periods. We believe the non-GAAP measures provide useful information to both management and users of the financial statements by excluding certain expenses and gains and losses that may not be indicative of core operating results and business outlook. These non-GAAP measures are not in accordance with, or an alternative to, measures prepared in accordance with GAAP and may be different from non-GAAP measures used by other companies. In addition, these non-GAAP measures are not based on any comprehensive set of accounting rules or principles. These measures should only be used to evaluate our results of operations in conjunction with the corresponding GAAP measures.

We define Consolidated Adjusted EBITDA as net 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 and accretion, interest expense, net and income tax expense; then reduced by the non-cash impact of equity earnings from equity method investments and increased by cash distributions from equity method investments and impairment of long-lived assets. Because Consolidated Adjusted EBITDA omits certain non-cash items, we believe that the measure is less susceptible to variances that affect our operating performance.

We define PGI Segment Adjusted EBITDA as 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 its ongoing operating performance: depreciation, amortization, depletion and accretion, interest expense, net and impairment of long-lived assets. When used in conjunction with GAAP financial measures, PGI Segment Adjusted EBITDA is a supplemental measure of operating performance that management believes is a useful measure for each of our PGI and RC segment's performance relative to the performance of competitors as well as performance period over period. Additionally, we believe the measure is less susceptible to variances that affect our operating performance results.

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.

We present these non-GAAP measures because we believe they are useful as supplemental measures in evaluating the performance of our operating performance and provide greater transparency into the results of operations. Management uses these non-GAAP measures in evaluating the performance of our business.

With the exception of impairment, the adjustments to Consolidated Adjusted EBITDA, PGI Segment Adjusted EBITDA and RC Segment Adjusted EBITDA in future periods are generally expected to be similar. 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, 2020, we have two reportable segments: (1) RC and (2) PGI. The business segment measurements provided to and evaluated by our chief operating decision maker are computed in accordance with the principles listed below:

• The accounting policies of the operating segments are the same as those described in the summary of significant accounting policies in the 2019 Form 10-K.

• Segment revenues include equity method earnings and losses from our equity method investments.

• Segment operating income (loss) includes segment revenues and allocation of certain "Corporate general and administrative expenses," which include Payroll and benefits, Rent and occupancy, Legal and professional fees, and General and administrative.

• RC segment operating income includes interest expense directly attributable to the RC segment.

The principal products and services of our segments are:

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 include Tinuum Group, Tinuum Services and other immaterial equity method investments. Segment revenues include our equity method earnings (losses) from our equity method investments and royalty earnings from Tinuum Group. These earnings are included within the Earnings from equity method investments and License royalties, related party line items in the Condensed Consolidated Statements of Operations. Key drivers to the RC segment performance are the produced and sold RC from both operating and retained RC facilities, royalty-bearing tonnage and the number of operating (leased or sold) and retained RC facilities. These key drivers impact our earnings and cash distributions from equity method investments.

2. PGI - Our PGI segment includes revenues and related expenses from the sale of consumable products that utilize PAC and chemical technologies. These options provide coal-powered utilities and industrial boilers with mercury control solutions working in conjunction with pollution control equipment systems, generally without the requirement for significant ongoing capital outlays. These amounts are included within the respective revenues and cost of revenue line items in the Condensed Consolidated Statements of Operations.

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.

Included in RC segment operating income for the three and six months ended June 30, 2019 is 453A interest expense of $0.3 million and $0.6 million, respectively.

(2) Included in PGI segment operating loss for the three and six months ended June 30, 2020 is $23.2 million and $23.2 million, respectively, of impairment expense on PGI segment and certain other long-lived assets, and $0.4 million and $0.4 million, respectively, of expenses related to sequestration of certain of our employees at our manufacturing plant in Louisiana. Included in PGI segment operating loss for the three and six months ended June 30, 2020 and 2019 is $1.4 million and $3.4 million, respectively, of depreciation, amortization, and depletion expense on mine and plant long-lived assets. Included in PGI segment operating loss for the three and six months ended June 30, 2019 is approximately $1.3 million and $4.7 million of costs recognized as a result of the step-up in inventory fair value recorded from the acquisition of Carbon Solutions.

RC

The following table details the segment revenues of our respective equity method investments:

	Three Months Ended June 30,
(in thousands)	2020		2019
Earnings from Tinuum Group	$	6,764	$	19,244
Earnings from Tinuum Services	1,404		1,693
Loss from other	—		(2		)
Earnings from equity method investments	$	8,168	$	20,935

For the three months ended June 30, 2020 and June 30, 2019

RC earnings decreased primarily due to a decrease in equity earnings in Tinuum Group for the three months ended June 30, 2020 compared to the corresponding quarter in 2019.

For the three months ended June 30, 2020, equity earnings from our interest in Tinuum Group were positively impacted by the addition of two new RC facilities during the second half of 2019. However, equity earnings from Tinuum Group for the three months ended June 30, 2020 decreased from the comparable quarter in 2019 primarily from higher depreciation recognized of

37

approximately $2.5 million for the three months ended June 30, 2020 on all Tinuum Group RC facilities as a result of a reduction in RC facilities estimated useful lives as determined by Tinuum Group during the second half of 2019. Further contributing to the decrease in equity earnings quarter over quarter was the restructuring of RC facility leases with Tinuum Group's largest customer, which decreased lease payments and equity earnings beginning in the second half of 2019. We believe the increase in depreciation and the decrease in lease payments will negatively impact equity earnings for the remainder of 2020 as well as 2021.

For the three months ended June 30, 2020 and 2019, we recognized $6.8 million and $19.2 million, respectively, in equity earnings from Tinuum Group, which was equal to our proportionate share of Tinuum Group's net income for those quarters. 

For the three months ended June 30, 2020, earnings from Tinuum Services decreased compared to the corresponding quarter in 2019 primarily due to a decrease in the number of operating RC facilities in which Tinuum Services provides operating and maintenance services from 20 to 19.

As noted above, for the three months ended June 30, 2020, RC earnings were impacted by a decrease in license royalties earned from Tinuum Group under the M-45 License. For the three months ended June 30, 2020 and 2019, there were 9.2 million tons and 9.6 million tons, respectively, of RC produced using the M-45 Technology. This decrease combined with a lower royalty rate per ton resulted in a decrease in license royalties quarter over quarter. The reduction in the royalty rate per ton was primarily attributable to higher depreciation recognized on all royalty bearing RC facilities as a result of a reduction in their estimated useful lives as determined by Tinuum Group in the second half of 2019. Further reducing the rate per ton was a decrease in net lease payments as a result of Tinuum Group restructuring RC facility contracted leases with its largest customer in the second half of 2019.

Future earnings and growth in the RC segment will continue to be impacted by coal-fired electricity generation dispatch and invested facilities with leases subject to periodic renewals being terminated, repriced, or otherwise subject to renegotiated terms.

Additional discussion of our equity method investments is included above within our consolidated results and in Note 6 of the Condensed Consolidated Financial Statements.

PGI

Discussion of revenues derived from our PGI segment and costs related thereto are included above within our consolidated results.

For the three months ended June 30, 2020 and June 30, 2019

PGI segment operating loss increased for the three months ended June 30, 2020 compared to the three months ended June 30, 2019 primarily due to the impairment charge of $23.2 million and a reduction in consumable revenue and associated margins and costs incurred related to COVID-19. For the three months ended June 30, 2020, consumables revenue and margins also continued to be negatively impacted by low coal-fired power dispatch driven by power generation from sources other than coal.

During the three months ended June 30, 2020 , we incurred costs of $0.4 million related to sequestration of certain of our employees at our manufacturing plant in Louisiana. These costs included hazardous pay, lodging expense and other related costs for 60 days.

RC

For the six months ended June 30, 2020 and June 30, 2019

For the six months ended June 30, 2020, we recognized $13.2 million in equity earnings from Tinuum Group, which was equal to our proportionate share of Tinuum Group's net income for the period. For the six months ended June 30, 2019, we recognized $39.0 million in equity earnings from Tinuum Group, which was equal to our proportionate share of Tinuum Group's net income of $40.7 million for the period less the recovery of the cash distributions in excess of the cumulative earnings as of December 31, 2018. The difference between our pro-rata share of Tinuum Group's net income and our earnings from our Tinuum Group equity method investment as reported on the Condensed Consolidated Statements of Operations for the six months ended June 30, 2019 was the result of cumulative distributions received from Tinuum Group being in excess of the carrying value of the investment, and therefore we recognized such excess distributions as equity method earnings in the period the distributions occurred.

For the six months ended June 30, 2020, equity earnings from our interest in Tinuum Group were positively impacted by the addition of two new RC facilities during the second half of 2019. However, equity earnings from Tinuum Group for the six months ended June 30, 2020 decreased from the comparable period in 2019 primarily from two new RC facilities during the six months ended June 30, 2019 that were recognized as point-in-time sales. Further, the decrease in equity earnings was due to higher depreciation recognized of approximately $4.9 million for the six months ended June 30, 2020 on all Tinuum Group RC facilities as a result of a reduction in RC facilities estimated useful lives as determined by Tinuum Group during the second half of 2019. Further contributing to the decrease in equity earnings for the six months ended June 30, 2020 compared to the six months ended June 30, 2019 was the restructuring of RC facility leases with Tinuum Group's largest customer, which decreased lease payments and equity earnings beginning in the second half of 2019. Furthermore, two coal-fired utilities in which Tinuum Group has invested RC facilities announced expected closures in the fourth quarter of 2019 and the associated leases of those facilities terminated during that period. As a result of higher depreciation, reduced lease payments and closures of two utilities, we expect our pro-rata share of Tinuum Group’s earnings will be lower for the remainder of 2020 as well as 2021.

As of June 30, 2020 and 2019, Tinuum Group had 20 and 21 invested RC facilities, respectively, that were generating revenues.

Equity earnings from our interest in Tinuum Services decreased during the six months ended June 30, 2020 compared to the six months ended June 30, 2019. During the six months ended June 30, 2020 and 2019, Tinuum Services provided operating and maintenance services to 19 and 20 operating RC facilities, respectively, which was the primary driver in the decrease in equity earnings. Tinuum Services derives earnings under fixed-fee arrangements as well as fee arrangements that are based on actual RC production, depending on the specific RC facility operating and maintenance agreement.

RC earnings were negatively impacted during the six months ended June 30, 2020 by a decrease in royalties earned from Tinuum Group under the M-45 License. During the six months ended June 30, 2020 and 2019, there were 21.1 million tons and 20.5 million tons, respectively, of RC produced using the M-45 Technology. While tonnage increased period over period, there was a reduction in the royalty rate per ton primarily attributable to higher depreciation recognized of approximately $1.5 million on all royalty bearing RC facilities as a result of a reduction in their estimated useful lives as determined by Tinuum Group in the second half of 2019. Further reducing the rate per ton was a decrease in net lease payments of approximately $0.7 million as a result of Tinuum Group restructuring RC facility contracted leases with its largest customer in the second half of 2019.

39

Future earnings and growth within the RC segment will continue to be impacted by coal-fired dispatch, and invested facilities with leases subject to periodic renewals being terminated, repriced, or otherwise subject to renegotiated terms.

Liquidity and Capital Resources

Overview of Factors Affecting Our Liquidity

During the six months ended June 30, 2020, our liquidity position was positively affected primarily due to distributions from Tinuum Group and Tinuum Services, royalty payments from Tinuum Group and borrowing availability under our bank ("Lender") line of credit ("Line of Credit").

Our principal sources of cash included:

• cash on hand;

• distributions from Tinuum Group and Tinuum Services;

• royalty payments from Tinuum Group; and

• cash proceeds received from under the Paycheck Protection Program ("PPP") administered by th U.S. Small Business Administration ("SBA").

Our principal uses of cash for the six months ended June 30, 2020 included:

• payment of dividends;

• payment of debt principal and interest;

• repurchases of shares of common stock; and

• our business operating expenses, including federal and state tax payments, cash severance payments and costs associated with COVID-19.

Our ability to continue to generate sufficient cash flow required to meet ongoing operational needs and obligations, capital expenditures, future potential dividend payments and potential future share repurchases depends on several factors, including executing on our contracts and initiatives, receiving license royalty payments from Tinuum Group and distributions from Tinuum Group and Tinuum Services, and increasing our share of the market for PGI consumables, including expanding our overall PAC business into additional adjacent markets. Increased distributions from Tinuum Group will likely be dependent upon both preserving existing contractual relationships and securing additional tax equity investors for those Tinuum Group facilities that are currently not operating.

We incur significant recurring capital expenditures for our AC manufacturing facility and for mine development at our lignite mine. For 2020, we anticipate that our capital expenditures will be lower than 2019 as we do not anticipate having significant planned maintenance as we incurred in 2019.

Our liquidity was negatively impacted from COVID-19 due to increased operating losses in our PGI segment from higher operating costs as a result of measures taken to support our ability to deliver as a critical infrastructure business, primarily from sequestration efforts and "hazard pay," which is a premium on wages, for a substantial number of our employees, and overall plant operating inefficiencies. However, in April 2020, we took steps to enhance our short-term liquidity through the PPP as discussed below.

Tinuum Group and Tinuum Services Distributions

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

our consolidated cash flow results for the six months ended June 30, 2020 and 2019:

	Six Months Ended June 30,
(in thousands)	2020		2019
Tinuum Group	$	27,364	$	33,788
Tinuum Services	5,152		4,300
Distributions from equity method investees	$	32,516	$	38,088

Cash distributions from Tinuum Group for the six months ended June 30, 2020 decreased by $6.4 million compared to the six months ended June 30, 2019 primarily due to reductions in lease payments received by Tinuum Group from its largest customer as a result of renegotiations of certain leases, which occurred in the second half of 2019 between Tinuum Group and this customer, and the shuttering of two coal-fired utilities in the fourth quarter of 2019 where two invested RC facilities were operating.

Future cash flows from Tinuum through 2021 are expected to range from $100 to $125 million, a decrease from the previously reported range of $125 to $150 million. The key drivers in achieving these future cash flows are based on the following:

• 20 invested facilities as of June 30, 2020 and inclusive of all net Tinuum cash flows (distributions and license

royalties), offset by estimated federal and state income tax payments and 453A interest payments.

41

Expected future cash flows from Tinuum Group are based on the following key assumptions:

• Tinuum Group continues to not operate retained facilities;

• Tinuum Group does not have material unexpected capital expenditures or unusual operating expenses;

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

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

PPP Loan

On April 21, 2020, we entered into a loan (the "PPP Loan") under the PPP through BOK, NA dba Bank of Oklahoma (the "Lender") providing for $3.3 million in proceeds, which amount was funded on April 21, 2020. The PPP Loan matures April 21, 2022 and provides for 18 monthly payments of principal and interest commencing on November 21, 2020. The interest rate on the PPP Loan is 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 the Lender, or breaching the terms of the PPP Loan. The occurrence of an event of default may result in the repayment of all amounts outstanding, collection of all amounts owing from us, or filing suit and obtaining judgment against us. The PPP Loan may be forgiven subject to the terms of the PPP and approval by the SBA.

Our business has been classified as an essential business and therefore we continue to operate on a modified basis to comply with governmental restrictions and public health authority guidelines. In April 2020, we sequestered approximately 60 employees to continue to run our manufacturing plant and build-up inventory in order to supply our customers. This resulted in additional costs as the sequestered employees received hazard pay. We used proceeds from the PPP Loan to fund these additional employment expenses and other payroll costs.

Senior Term Loan

On December 7, 2018, we and ADA-ES, Inc. ("ADA"), a wholly-owned subsidiary, and certain other subsidiaries of the Company as guarantors, The Bank of New York Mellon as administrative agent, and Apollo Credit Strategies Master Fund Ltd and Apollo A-N Credit Fund (Delaware) L.P. (collectively "Apollo”), affiliates of a beneficial owner of greater than five percent of our common stock and a related party, entered into the Term Loan and Security Agreement (the "Senior Term Loan") in the amount of $70.0 million, less original issue discount of $2.1 million. Proceeds from the Senior Term Loan were used to fund the acquisition of Carbon Solutions as disclosed in Note 4. We also paid debt issuance costs of $2.0 million related to the Senior Term Loan. The Senior Term Loan has a term of 36 months and bears interest at a rate equal to 3-month LIBOR (subject to a 1.5% floor) + 4.75% per annum, which is adjusted quarterly to the current 3-month LIBOR rate, and interest is payable quarterly in arrears. Quarterly principal payments of $6.0 million are required and commenced in March 2019, and we may prepay the Senior Term Loan at any time without penalty. The Senior Term Loan is secured by substantially all of our assets, including the cash flows from Tinuum Group and Tinuum Services (collectively, the "Tinuum Entities"), but excluding our equity interests in those Tinuum entities. During the six months ended June 30, 2020, we made principal payments of $12.0 million.

The Senior Term Loan includes, among others, the following covenants: (1) Beginning December 31, 2018 and as of the end of each fiscal quarter thereafter, we must maintain a minimum cash balance of $5.0 million and shall not permit "expected future net cash flows from the refined coal business" (as defined in the Senior Term Loan) to be less than 1.75 times the outstanding principal amount of the Senior Term Loan; (2) Beginning in January 2019, annual collective dividends and buybacks of shares of our common stock in an aggregate amount, not to exceed $30.0 million, is permitted so long as (a) no default or event of default exists under the Senior Term Loan and (b) expected future net cash flows from the refined coal business as of the end of the most recent fiscal quarter exceed $100.0 million.

Pursuant to entering into the PPP Loan, on April 20, 2020, we and Apollo executed the First Amendment to the Senior Term Loan, which permitted us to enter into the PPP Loan.

Stock Repurchases and Dividends

In November 2018, our Board of Directors (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.

For the six months ended June 30, 2020, under the Stock Repurchase Program, we purchased 20,613 shares of our common stock for cash of $0.2 million, inclusive of commissions and fees. For the six months ended June 30, 2019, under the Stock

42

Repurchase Program, we purchased 248,591 shares of our common stock for cash of $2.8 million, inclusive of commissions and fees. As of June 30, 2020, we had $7.0 million remaining under the Stock Repurchase Program.

For the six months ended June 30, 2020 and 2019, we declared and paid quarterly cash dividends to stockholders of $4.8 million and $9.2 million, respectively.

Line of Credit

On December 7, 2018, ADA-ES, Inc. ("ADA"), a wholly-owned subsidiary, as borrower, we, as guarantor, and the Lender entered into an amendment to the Line of Credit. This amendment provided, among other things, for ADA to be able to enter into the Senior Term Loan as a guarantor so long as the principal amount of the Senior Term Loan did not exceed $70.0 million. Additionally, the financial covenants in the Line of Credit were amended and restated to be consistent with the Senior Term Loan covenants, including maintaining a minimum cash balance of $5.0 million. The maturity date of the Line of Credit is September 30, 2020.

As of June 30, 2020, we have $5.0 million of borrowing availability and no outstanding borrowings under the Line of Credit.

Sources and Uses of Cash

Six Months Ended June 30, 2020 vs. Six Months Ended June 30, 2019

Cash, cash equivalents and restricted cash increased from $17.1 million as of December 31, 2019 to $21.7 million as of June 30, 2020. The following table summarizes our cash flows for the six months ended June 30, 2020 and 2019, respectively:

	Six Months Ended June 30,
(in thousands)	2020			2019			Change
Cash and cash equivalents and restricted cash provided by (used in):
Operating activities	$	24,085		$	30,572		$	(6,487	)
Investing activities	(4,696		)	(4,979		)	283
Financing activities	(14,736		)	(28,945		)	14,209
Net change in cash and cash equivalents and restricted cash	$	4,653		$	(3,352	)	$	8,005

Cash flow from operating activities

Cash flows provided by operating activities for the six months ended June 30, 2020 decreased by $6.5 million compared to the six months ended June 30, 2019. The net decrease was primarily attributable to a decrease in net income for the six months ended June 30, 2020 compared to net income for the six months ended June 30, 2019 of $48.2 million, a decrease period over period in distributions from equity method investments, return on investment of $5.6 million, and a decrease in the net change in inventories, net of $4.4 million. Offsetting this net decrease in cash flows provided by operating activities was a decrease period over period in earnings from equity method investees of $26.2 million and an increase of $5.0 million in the net change in accrued payroll and related liabilities for the six months ended June 30, 2020 compared to the six months ended June 30, 2019.

Cash flow from investing activities

Cash flows used in investing activities for the six months ended June 30, 2020 decreased by $0.3 million compared to the six months ended June 30, 2019 primarily from a decrease in cash consideration paid for the six months ended June 30, 2019 of $0.7 million related to the acquisition of Carbon Solutions. Offsetting this decrease in cash flows used in investing activities was an increase period over period in capital expenditures related to property, plant equipment and intangibles of $0.4 million.

Cash flow from financing activities

Cash flows used in financing activities for the six months ended June 30, 2020 decreased by $14.2 million compared to the six months ended June 30, 2019 primarily from proceeds received from the PPP Loan of $3.3 million in April 2020 and decreases period over period in dividends of $4.4 million, principal loan repayments on the Senior Term Loan of $4.0 million and repurchases of common shares of $2.7 million.

Contractual Obligations

During the six months ended June 30, 2020, there were no material changes to our contractual obligations outside of the ordinary course of business from those reported as of December 31, 2019.

Item 4. Controls and Procedures

Evaluation of Disclosure Controls and Procedures

As required by Rule 13a‑15(b) under the Securities Exchange Act of 1934, as amended (the "Exchange Act"), we have evaluated, under the supervision of and with the participation of our management, including our principal executive officer and principal financial officer, the effectiveness of the design and operation of our disclosure controls and procedures (as defined in Rules 13a‑15(e) and 15d‑15(e) under the Exchange Act) as of the end of the period covered by this report. Our disclosure controls and procedures are designed to ensure that information required to be disclosed in the reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms. Based upon this evaluation, our principal executive officer and principal financial officer concluded that our disclosure controls and procedures were effective as of June 30, 2020.

Changes in Internal Control Over Financial Reporting

There have been no changes in our internal control over financial reporting (as defined in Rules 13a‑15(f) and 15d‑15(f) under the Exchange Act) during the fiscal quarter ended June 30, 2020 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

PART II. OTHER INFORMATION

Item 1. Legal Proceedings

From time to time, we are involved in litigation, claims and other proceedings related to the conduct of our business. Information with respect to this item may be found in Note 10 "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 2019 Form 10-K except as set forth below. This risk factor should be read together with the risk factors in the 2019 Form 10-K.

The COVID-19 pandemic and ensuing economic downturn has affected, and is expected to continue to affect and pose risks to our business, results of operations, financial condition and cash flows; and other epidemics or outbreaks of infectious diseases may have a similar impact.

In March 2020, the WHO declared the outbreak of COVID-19 a global pandemic, which continues to spread throughout the United States ("U.S.") and the world and has resulted in authorities implementing numerous measures to contain the virus, including travel bans and restrictions, quarantines, shelter-in-place orders, and business limitations and shutdowns. We have been designated by CISA as a critical infrastructure supplier to the energy sector. This designation provides some latitude in continuing to conduct our business operations compared to companies in other industries and markets. While we are unable to accurately predict the full impact that COVID-19 will have on our results from operations, financial condition, liquidity and cash flows due to numerous uncertainties, including the duration and severity of the pandemic and containment measures, our compliance with these measures has impacted our day-to-day operations and could disrupt our business and operations, as well as that of our key customers, suppliers and other counterparties, for an indefinite period of time. To support the health and well-being of our employees, customers, partners and communities, a vast majority of our employees not directly involved in operating our plant, have been working remotely since March 2020. In addition, many of our customers are working remotely, which may delay the timing of some orders and deliveries expected in the second quarter of 2020 and beyond. The disruptions to our operations caused by COVID-19 may result in inefficiencies, delays and additional costs in our manufacturing, sales, marketing, and customer service efforts that we cannot fully mitigate through remote or other alternative work arrangements. Although such disruptions did not have a material adverse impact on our financial results for the first quarter of fiscal 2020, we incurred additional operating costs for the second quarter of fiscal year 2020, which included hazard pay, cleaning costs and sequestration costs related to our operating plant personnel. For the balance of 2020, we may see reduced demand for our products due to reduced interaction with our customers and our inability to target new customers and markets.

More generally, the pandemic raises the possibility of an extended global economic downturn and has caused volatility in financial markets, which could affect demand for our products and services and impact our results and financial condition even after the pandemic is contained and the shelter-in-place orders are lifted. For example, a decrease in orders in a given period could negatively affect our revenues in future periods, particularly if experienced on a sustained basis. We will continue to evaluate the nature and extent of the impact of COVID-19 to our business.

As previously disclosed, in April 2020, we entered into a loan (the "PPP Loan") in the amount of $3.3 million through a bank under the Paycheck Protection Program sponsored by the U.S. Small Business Administration ("SBA"). The PPP loan became available to us pursuant to the Coronavirus Aid, Relief, and Economic Security Act and is administered by the SBA. We entered into the PPP Loan to provide additional liquidity in light of our COVID-19-related higher employee costs. Proceeds from the PPP Loan were used to cover a portion of our existing payroll and related expenses, including sequestration pay for certain employees, as well as certain other operating costs as permitted under the Paycheck Protection Program. We expect that current cash and cash equivalent balances, inclusive of the PPP Loan, and cash flows that are generated from operations will be sufficient to meet our working capital needs and other capital and liquidity requirements for at least the next 12 months. However, if our business is more adversely impacted by COVID-19 than expected, and our personnel costs remain higher than budgeted, our cash needs could increase.

Further, we assessed the impact on our existing internal control over financial reporting as of March 31, 2020 and going forward under the current state of COVID-19. We performed procedures to ensure that existing internal control over financial reporting was operating effectively as March 31, 2020 and will continue to operate effectively for the foreseeable future. Such procedures included, but were not limited to, developing a COVID- 19 risk assessment identifying the risks of fraud, changes required in our internal control framework as well as other business information technology and cybersecurity risks. As a result of these procedures and conclusions reached, we did not implement any changes to our internal control over financial reporting as of June 30, 2020.
