Advanced Emissions Solutions, Inc. and Subsidiaries
Notes to Condensed Consolidated Financial Statements
(Unaudited)


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 Highlands Ranch, 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. The Company generates substantial earnings and tax credits under Section 45 ("Section 45 tax credits") of the Internal Revenue Code ("IRC") from its equity investments in certain entities and earns royalties for technologies that are licensed to Tinuum Group, LLC, a Colorado limited liability company ("Tinuum Group"). Such technologies allow Tinuum Group to provide their customers with various solutions to enhance combustion and reduced emissions of nitrogen oxide ("NOx") and mercury from coal burned to generate electrical power. The Company’s sales occur principally throughout the United States. See Note 13 for additional information regarding the Company's operating segments.
On December 7, 2018 (the "Acquisition Date"), the Company acquired (the "Carbon Solutions Acquisition") 100% of the equity interests of ADA Carbon Solutions, LLC (“Carbon Solutions”). Carbon Solutions is a manufacturer and seller of 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 powdered activated carbon. Carbon Solutions was formed in 2008 as a 50/50 joint venture by the Company and Energy Capital Partners LLC. The Company relinquished its ownership in 2011 as part of a legal settlement agreement as described in the Company's Annual Report on Form 10-K for the fiscal year ended December 31, 2017. The Company acquired Carbon Solutions primarily to expand the Company's product offerings within the mercury control industry and other complementary PAC markets.
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, LLC ("Tinuum Services"), and GWN Manager, LLC ("GWN Manager"), which are accounted for under the equity method of accounting, and Highview Enterprises Limited (the "Highview Investment"), which is accounted for in accordance with U.S. GAAP applicable to equity investments that do not qualify for the equity method of accounting.
Results of operations and cash flows for the interim periods are not necessarily indicative of the results that may be expected for the entire year. All significant intercompany transactions and accounts were eliminated 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, 2018 (the "2018 Form 10-K"). Significant accounting policies disclosed therein have not changed, except as described later in Note 1.
Earnings Per Share
Basic earnings per share is computed using the two-class method, which is an earnings allocation formula that determines earnings per share for common stock and any participating securities according to dividend and participating rights in undistributed earnings. The Company's restricted stock awards ("RSA's") granted prior to December 31, 2016 contain non-forfeitable rights to dividends or dividend equivalents and are deemed to be participating securities. RSA's granted subsequent to December 31, 2016 do not contain non-forfeitable rights to dividends and are not deemed to be participating securities.
Under the two-class method, net income for the period is allocated between common stockholders and the holders of the participating securities based on the weighted-average number of common shares outstanding during the period, excluding participating, unvested RSA's ("common shares"), and the weighted-average number of participating unvested RSA's

(Unaudited)

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 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.

For the three and six months ended June 30, 2019 and 2018, RSA's and Stock Options convertible to 0.3 million and 0.3 million shares, respectively, and 0.3 million and 0.4 million shares, respectively, of common stock for each of the periods presented were outstanding but were not included in the computation of diluted net income per share because the effect would have been anti-dilutive. For the six months ended June 30, 2018, Stock Options to purchase 0.1 million shares, which vest based on the Company achieving specified performance targets, were outstanding, but were not included in the computation of diluted net income per share for a portion of this period because they were determined not to be contingently issuable.
Use of Estimates
The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. There have been no changes in the Company’s critical accounting estimates from those that were disclosed in the 2018 Form 10-K. Actual results could differ from these estimates.
Risks and Uncertainties
The Company’s earnings are significantly affected by equity earnings it receives from Tinuum Group. As of June 30, 2019, Tinuum Group has 21 invested RC facilities of which 11 are leased to a single customer. A majority of these leases are periodically renewed and the loss of this single customer or material modification to the lease terms of these facilities by this customer would have a significant adverse impact on Tinuum Group's financial position, results of operations and cash flows, which in turn would have material adverse impact on the Company’s financial position, results of operations and cash flows.
The Company's revenues, sales volumes, earnings and cash flows are significantly affected by prices of competing power generation sources such as natural gas and renewable energy. Low natural gas prices make it a competitive alternative to coal-fired power generation and therefore, coal consumption may be reduced, which reduces the demand for our products. In addition, coal consumption and demand for our products is also affected by the demand for electricity, which is higher in the warmer and colder months of the year. Abnormal temperatures during the summer and winter months may significantly reduce coal consumption and thus the demand for our products.

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

See Note 6 for additional disclosures required under ASC 842 in the year of adoption.
As of January 1, 2019, Tinuum Group adopted ASU 2016-02 and ASU 2014-09 (Topic 606), Revenue from Contracts with Customers ("ASU 2014-09"). As a result of Tinuum Group’s adoption of these pronouncements, the Company recorded a cumulative effect increase of $28.8 million to Retained earnings as of January 1, 2019, based on the Company's ownership percentage of Tinuum Group's cumulative effect adjustment, and increased its investment balance in Tinuum Group in the amount of $37.2 million and established a deferred tax liability of $8.4 million. As a result of the increase in the investment balance in Tinuum Group, for the six months ended June 30, 2019, the Company began recognizing equity earnings in Tinuum Group based on its pro-rata share of Tinuum Group’s net income rather than based on cash distributions received as had been required in prior periods as a result of the cumulative cash distributions exceeding the cumulative pro-rata share of Tinuum Group's net income.
Not Yet Adopted
In June 2016, the FASB issued ASU 2016-13, Financial Instruments - Credit Losses (Topic 326) Measurement of Credit Losses on Financial Instruments ("ASU 2016-13"). The main objective of ASU 2016-13 is to provide financial statement users with more decision-useful information about the expected credit losses on financial instruments and other commitments to extend credit held by a reporting entity at each reporting date. To achieve this objective, the amendments in ASU 2016-13 replace the incurred loss impairment methodology in current U.S. GAAP with a methodology that reflects expected credit losses and requires consideration of a broader range of reasonable and supportable information to inform credit loss estimates. ASU 2016-13 is effective for fiscal years beginning after December 15, 2019, including interim periods within those years, and must be adopted under a modified retrospective method approach. Entities may adopt ASU 2016-13 earlier as of the fiscal years beginning after December 15, 2018, including interim periods within those years. The Company is currently evaluating the provisions of this guidance and assessing its impact on the Company's financial statements and disclosures. The Company does not believe this standard will have a material impact on the Company's financial statements and disclosures.
In August 2018, the FASB issued ASU 2018-13, Fair Value Measurement (Topic 820) Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement ("ASU 2018-13"). The amendments in ASU 2018-13 improve the effectiveness of fair value measurement disclosures and modify the disclosure requirements on fair value measurements in Topic 820, Fair Value Measurement ("Topic 820"), based on the concepts in FASB Concepts Statement, Conceptual Framework for Financial Reporting - Chapter 8: Notes to Financial Statements, including the consideration of costs and benefits.

2018-13 is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. The amendments on changes in unrealized gains and losses, the range and weighted-average of significant unobservable inputs used to develop Level 3 fair value measurements, and the narrative description of measurement uncertainty should be applied prospectively for only the most recent interim or annual period presented in the initial fiscal year of adoption. All other amendments should be applied retrospectively to all periods presented upon their effective date. Early adoption is permitted upon issuance of this update. An entity is permitted to early adopt any removed or modified disclosures upon issuance of this update and delay adoption of the additional disclosures until their effective date. The Company is currently evaluating the provisions of ASU 2018-13 and assessing its impact on the Company's financial statement disclosures. The Company does not believe this standard will have a material impact on the Company's financial statement disclosures.

Note 2 - Acquisition
As described in Note 1, on the Acquisition Date, the Company completed the Carbon Solutions Acquisition for a total purchase price of $75.0 million (the "Purchase Price"). The results of Carbon Solutions have been included in the Company’s consolidated financial statements since the Acquisition Date. The fair value of the purchase consideration totaled $66.5 million and consisted of cash of $65.8 million and an additional purchase adjustment amount payable to Carbon Solutions' secured lender of $0.7 million, which was paid in March 2019. The Purchase Price was adjusted by assumed debt and contractual commitments of $11.8 million, less cash acquired of $3.3 million. The Company also paid $4.5 million in acquisition-related costs (or transaction costs) during the year ended December 31, 2018. The Company funded the cash consideration from cash on hand and the proceeds from the Term Loan and Security Agreement (the "Senior Term Loan") in the principal amount of $70.0 million, as more fully described in Note 5.

The following table summarizes the final purchase price allocation. Subsequent to December 31, 2018, the Company completed additional analysis and adjustments were made to the preliminary purchase price allocations as noted in the table below:

Adjustments to the preliminary purchase price allocation primarily relate to changes in fair values assigned to property, plant and equipment, intangible assets, mine reclamation liability and the related mine reclamation asset as a result of the final valuation report from the Company's third-party valuation firm issued in May 2019. In addition, during the six months ended June 30, 2019 and based on new information of facts and circumstances that existed as of the Acquisition Date, the Company revised its estimate 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 adjustments have been recorded as of June 30, 2019 and are included in the Consolidated Balance Sheet as of June 30, 2019 and the resultant impact to the Statement of Operations for the three and six months ended June 30, 2019.

Unaudited Pro Forma Financial Information
The following represents the pro forma effects of the Carbon Solutions Acquisition as if it had occurred on January 1, 2017. The pro forma pre-tax income for the period presented has been calculated after applying the Company’s accounting policies in effect for 2017 and 2018. In addition, pro forma net income for the three and six months ended June 30, 2018 includes: (1) the impact on Carbon Solutions of the adoption of ASC 606 effective January 1, 2018, which resulted in a reclassification of $1.8 million and $3.8 million, respectively, from Revenues to Cost of Revenue for freight costs billed to customers, with no impact to income from operations; (2) the reduction in depletion, depreciation and amortization resulting from the purchase price adjustments to Property, plant and equipment and Mine development costs; (3) the adjustment to interest expense from the combination of the Senior Term Loan that was used to fund the Carbon Solutions Acquisition and the elimination of certain debt of Carbon Solutions as a result of pay-offs by the Company as of the Acquisition Date; and (4) the removal of $2.1 million and $3.2 million in transaction costs incurred for the three and six months ended June 30, 2018, respectively, together with the income tax effect on (1) through (4). The pro forma results do not include any anticipated synergies or other expected benefits of the Carbon Solutions Acquisition. The unaudited pro forma financial information below is not necessarily indicative of either future results of operations or results that might have been achieved had the Carbon Solutions Acquisition been consummated as of January 1, 2017.
As of June 30, 2019, the Company identified a difference in depreciation as originally calculated and included in the pro forma net income disclosure for the three months ended March 31, 2018.

Note 4 - Equity Method Investments
Tinuum Group, LLC
The Company's ownership interest in Tinuum Group was 42.5% as of June 30, 2019 and December 31, 2018. Tinuum Group supplies technology equipment and technical services at select coal-fired generators, but its primary purpose is to put into operation facilities that produce and sell refined coal ("RC") that lower emissions and therefore 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.

For the three and six months ended June 30, 2018 periods presented in the table below, 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, as discussed below.
For the three and six months ended June 30, 2018 periods presented in the table below, the Company recognized equity earnings from Tinuum Group to the extent that cash distributions were received from Tinuum Group during the period. For 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 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. For the three and six months ended June 30, 2018, the Company recognized equity earnings from Tinuum Group of $14.5 million and $25.5 million, respectively. As of June 30, 2019 and December 31, 2018, the Company's carrying value in Tinuum Group was $42.5 million and zero, respectively.

(1) As discussed in Note 1, Tinuum Group adopted ASC 606 and ASC 842 as of January 1, 2019. As a result of Tinuum Group’s adoption of these standards, the Company recorded a cumulative adjustment of $28.8 million, net of the impact of income taxes, related to the Company's percentage of Tinuum Group's cumulative effect adjustment that increased the Company's Retained earnings as of January 1, 2019.
(2) For the three and six months ended June 30, 2018, the amount of the Company's 42.5% proportionate share of net income available to members as shown in the table above may differ from mathematical calculations of the Company’s 42.5% equity interest in Tinuum Group multiplied by the amounts of net income available to members as shown in the table above of Tinuum Group results of operations due to adjustments related to the Class B preferred return.

Tinuum Services, LLC
The Company has a 50% voting and economic interest in Tinuum Services, which is equivalent to the voting and economic interest of NexGen Refined Coal, LLC ("NexGen"). The Company has determined that Tinuum Services is not a VIE and has evaluated its consolidation analysis under the voting interest model. Because the Company does not own greater than 50% of the outstanding voting shares, either directly or indirectly, it has accounted for its investment in Tinuum Services under the equity method of accounting. The Company’s investment in Tinuum Services as of June 30, 2019 and December 31, 2018 was $5.9 million and $6.6 million, respectively.

Senior Term Loan
On December 7, 2018, the Company, and ADA-ES, Inc. ("ADA"), a wholly-owned subsidiary, and certain other subsidiaries of the Company as guarantors, The Bank of New York Mellon as administrative agent, and Apollo Credit Strategies Master Fund Ltd and Apollo A-N Credit Fund (Delaware) L.P. (collectively "Apollo”), affiliates of a beneficial owner of greater than five percent of the Company's common stock and a related party, entered into the Senior Term Loan in the amount of $70.0 million less original issue discount of $2.1 million. Proceeds from the Senior Term Loan were used to fund the Carbon Solutions Acquisition as disclosed in Note 2. The Company also paid debt issuance costs of $2.0 million related to the Senior Term Loan. The Senior Term Loan has a term of 36 months and bears interest at a rate equal to 3-month LIBOR (subject to a 1.5% floor) + 4.75% per annum, which is adjusted quarterly to the current 3-month LIBOR rate, and interest is payable quarterly in arrears. Quarterly principal payments of $6.0 million were required beginning in March 2019, and the Company may prepay the Senior Term Loan at any time without penalty. The Senior Term Loan is secured by substantially all of the assets of the Company, including the cash flows from Tinuum Group and Tinuum Services (collectively, the "Tinuum Entities"), but excluding the Company's equity interests in the Tinuum entities.
The Senior Term Loan includes, among others, the following covenants: (1) Beginning December 31, 2018 and as of the end of each fiscal quarter thereafter, the Company must maintain a minimum cash balance of $5.0 million and shall not permit "expected future net cash flows from the refined coal business" (as defined in the Senior Term Loan) to be less than 1.75 times the outstanding principal amount of the Senior Term Loan; (2) Beginning in January 2019, annual collective dividends and buybacks of Company shares in an aggregate amount, not to exceed $30.0 million, is permitted so long as (a) no default or event of default exists under the Senior Term Loan and (b) expected future net cash flows from the refined coal business as of the end of the most recent fiscal quarter exceed $100.0 million.
Line of Credit
On September 30, 2018, ADA, as borrower, the Company, as guarantor, and a bank (the "Lender") entered into an amendment (the "Twelfth Amendment") to the 2013 Loan and Security Agreement (the "Line of Credit"). The Twelfth Amendment decreased the borrowing availability of the Line of Credit to $5.0 million due to decreased collateral requirements, extended the maturity date of the Line of Credit to September 30, 2020 and permitted the Line of Credit to be used as collateral (in place of restricted cash) for letters of credit ("LC's") up to $5.0 million related to equipment projects and certain other agreements. Under the Twelfth Amendment, there was no minimum balance requirement based on the Company meeting certain conditions and maintaining minimum trailing twelve-month EBITDA (earnings before interest, taxes, depreciation and amortization), as previously defined in the "Eleventh Amendment" to the Line of Credit, of $24.0 million.
On December 7, 2018, ADA, as borrower, the Company, as guarantor, and the Lender entered into an amendment to the Line of
Credit, which provided, among other things, for ADA to be able to enter into the Senior Term Loan as a guarantor so long as
the principal amount of the Senior Term Loan does not exceed $70.0 million. Additionally, the financial covenants in the Line
of Credit were amended and restated to be consistent with the aforementioned Senior Term Loan covenants, including
maintaining a minimum cash balance of $5.0 million.
As of June 30, 2019, there were no outstanding borrowings under the Line of Credit.

Note 6 - Leases
The financial statement impact from the adoption of ASC 842 as of January 1, 2019 is due to recording ROU assets and related lease liabilities for operating lease commitments that were outstanding as of December 31, 2018. The Company has elected the transitional practical expedients allowed under ASC 842, which include among other things that the Company need not reassess: (1) whether any existing contracts are or contain leases, inclusive of land easements; (2) the lease classification or lease term for existing leases; and (3) initial direct costs for any existing leases.
ASC 842 defines a lease as a contract, or part of a contract, that conveys the right to control the use of an identified asset for a period of time in exchange for consideration. Control over the use of an identified asset means that an entity has both the right to obtain substantially all of the economic benefits from the use of an identified asset and the right to direct the use of that identified asset. The determination of whether a contract contains a lease may require significant assumptions and judgments.
Historically, Carbon Solutions has used leasing to fund the majority of its capital needs for mining and manufacturing equipment. As of June 30, 2019, the Company has obligations under finance and operating leases in the amounts of $7.4 million and $5.5 million, respectively. ROU assets under finance leases are mining equipment used at the Company’s lignite mine, which provides the key raw materials for manufacturing the Company’s products. ROU assets under operating leases are primarily plant equipment used at the Company’s manufacturing facility, but also include other office equipment, vehicles and office facilities. As of June 30, 2019, the Company has ROU assets, net of accumulated amortization, under finance leases and operating leases of $7.0 million and $5.5 million, respectively.
Certain of the finance and operating leases have options permitting renewals for additional periods and buy-out options. Renewal and buy-out options for applicable leases have not been included in the measurement of the respective lease liabilities as the Company is not reasonably certain that it will exercise the respective option or the lessor does not have an exclusive right to exercise the option.
Variable lease payments represent payments made by a lessee for the right to use an underlying asset that vary because of changes in facts or circumstances occurring after the commence date of a lease other than the passage of time. Variable lease payments that are based on an index or rate, calculated by using the index or rate that exists on the lease commencement date, are included in the measurement of a lease liability. Certain of the Company’s operating leases for office facilities contain variable lease components that are not based on an index or rate, and the Company recognizes these payments as lease expense in the period in which the obligation for those payments is incurred.
The Company calculates lease liabilities based on the present value of lease payments discounted by the rate implicit in the lease or, if not readily determinable, the Company’s incremental borrowing rate.
The Company records lease liabilities and related ROU assets for all leases that have a term of greater than one year. For short-term leases (leases with terms of less than one year), the Company expenses lease payments on a straight-line basis over the lease term.
Finance leases
Leases classified as capital leases under ASC 840 and the related assets and liabilities were carried forward at their carrying values of $8.1 million and $8.2 million, respectively, as of December 31, 2018, and were classified as finance leases as of January 1, 2019. ROU assets under finance leases and finance lease liabilities are included in Property, plant and equipment and Current portion and Long-term portion of borrowings, respectively, in the Condensed Consolidated Balance Sheet as of June 30, 2019.
Finance lease liabilities are subsequently measured by increasing the carrying amount to reflect interest expense on the finance lease liability and reducing the carrying amount of the lease liability to reflect lease payments made during the period. Interest on finance lease liabilities is determined in each period during the lease term as the amount that produces a constant periodic discount rate on the remaining balance of the lease liability. ROU assets under finance leases are amortized over the remaining lease term on a straight-line basis. Interest expense related to finance lease liabilities and amortization of ROU assets under finance leases are included in Interest expense and Depreciation, amortization, depletion and accretion, respectively, in the Condensed Consolidated Statement of Operations for the three and six months ended June 30, 2019.
Operating leases
Operating lease liabilities as of January 1, 2019 were calculated at the present value, using a discount rate of the lease, of the remaining minimum rental payments (as defined under ASC 840). As the rate implicit in all of the operating leases was not readily determinable, the Company determined its discount rate as of January 1, 2019 based on an estimate of its incremental borrowing rate. This rate was based on the Company’s effective borrowing rate on the Senior Term Loan, considering the collateral requirements contained therein, in effect as of January 1, 2019. ROU assets under operating leases as of January 1,

15

Advanced Emissions Solutions, Inc. and Subsidiaries
Notes to Condensed Consolidated Financial Statements
(Unaudited)

2019 were determined as the calculated value of the operating lease liabilities less accrued lease payments and accrued lease incentives. As of December 31, 2018, the total amount of accrued lease payments and accrued lease incentives was approximately $0.1 million. ROU assets under operating leases and operating lease liabilities are included in Other long-term assets and Other liabilities and Other long-term liabilities, respectively, in the Condensed Consolidated Balance Sheet as of June 30, 2019.
Operating lease liabilities are subsequently measured at the present value of the lease payments not yet paid discounted using the discount rate for the lease established at the inception date of the lease (or January 1, 2019 for operating leases in effect as of December 31, 2018). ROU assets under operating leases are subsequently measured at the amounts of the related operating lease liability, adjusted for, as applicable, prepaid or accrued lease payments, the remaining balance of any lease incentives received, unamortized initial direct costs and impairment. Lease expense from operating leases is recognized as a single lease cost over the remaining lease term on a straight-line basis. Variable lease payments not included in operating lease liabilities are recognized as expense in the period in which the obligation for those payments is incurred. Lease expense for operating leases for the three and six months ended June 30, 2019 was $1.0 million and $2.2 million, respectively, of which $1.0 million and $2.1 million, respectively is included in Consumables - cost of revenue, exclusive of depreciation and amortization, and zero and $0.1 million, respectively, is included in General and administrative in the Condensed Consolidated Statement of Operations for the three and six months ended June 30, 2019.

Note 7 - Revenues
Contract Assets and Liabilities
Contract assets are comprised of unbilled receivables and are included in Receivables, net in the Condensed Consolidated Balance Sheet. Unbilled receivables represent a conditional right to consideration in exchange for goods or services transferred to a customer.
Trade receivables represent an unconditional right to consideration in exchange for goods or services transferred to a customer. The Company invoices its customers in accordance with the terms of the contract. Credit terms are generally net 30 from the date of invoice. The timing between the satisfaction of performance obligations and when payment is due from the customer is generally not significant. The Company records allowances for doubtful trade receivables when it is probable that the balances will not be collected.
Contract liabilities are comprised of deferred revenue, which represents an obligation to transfer goods or services to a customer for which the Company has received consideration from the customer and, if deliverable within one year or less, is included in

For the three and six months ended June 30, 2019, the Company recognized zero provision for bad debt expense, respectively, related to specific accounts whose ultimate collection was in doubt. During the three and six months ended June 30, 2018, the Company settled a previously recorded commitment for additional work related to a contract with a customer, which resulted in a reduction to Equipment sales cost of revenue, exclusive of depreciation and amortization of $0.3 million and bad debt expense of $0.2 million. Bad debt expense is included within the General and administrative line item in the Consolidated Statements of Operations.
Disaggregation of Revenue
During the three and six months ended June 30, 2019 and 2018, all performance obligations related to revenues recognized were satisfied at a point in time. The Company disaggregates its revenues by its major components as well as between its two operating segments, which are further discussed in Note 13 to the condensed consolidated financial statements.

Notes to Condensed Consolidated Financial Statements
(Unaudited)


Note 8 - 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 to 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, 2019.
Restricted Cash
As of June 30, 2019 and December 31, 2018, the Company had long-term restricted cash of $5.0 million and $5.2 million, respectively, which primarily consisted of minimum cash balance requirements under the Senior Term Loan. As of June 30, 2019 and December 31, 2018, the Company had short-term restricted cash of zero and $0.1 million, respectively, related to other commitments.
Tinuum Group
The Company also has certain limited obligations contingent upon future events in connection with the activities of Tinuum Group. The Company, NexGen and two 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. No liability or expense provision has been recorded by the Company related to this contingent obligation as the Company believes that it is not probable that a loss will occur with respect to Tinuum Group Party Guaranties.
Note 9 - 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. This stock repurchase program will remain in effect until December 31, 2019 unless otherwise modified by the Board. Previously, the Board had authorized the Company to purchase up to $20.0 million of its outstanding common stock under a separate repurchase program that was in effect until July 31, 2018.
For the three and six months ended June 30, 2019, under the respective stock repurchase program authorized by the Board,

Tax Asset Protection Plan
U.S. federal income tax rules, and Section 382 of the Internal Revenue Code in particular, could substantially limit the use of net operating losses and other tax assets if the Company experiences an "ownership change" (as defined in the Internal Revenue Code). In general, an ownership change occurs if there is a cumulative change in the ownership of the Company by "5 percent stockholders" that exceeds 50 percentage points over a rolling three-year period.
On May 5, 2017, the Board approved the declaration of a dividend of rights to purchase Series B Junior Participating Preferred Stock for each outstanding share of common stock as part of a tax asset protection plan (the "Tax Asset Protection Plan") designed to protect the Company’s ability to utilize its net operating losses and tax credits. The Tax Asset Protection Plan 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 6, 2018, the Board approved the First Amendment to the Tax Asset Protection Plan (the "First Amendment") that amends the Tax Asset Protection Plan dated May 5, 2017. The First Amendment amended the definition of "Final Expiration Date" under the Tax Asset Protection Plan to extend the duration of the TAPP and makes associated changes in connection therewith. At the Company's 2018 annual meeting of stockholders, the Company's stockholders approved the First Amendment, thus the Final Expiration Date will be the close of business on December 31, 2019, which was subsequently extended, as described below.
On April 5, 2019, the Board approved the Second Amendment to the Tax Asset Protection Plan (the "Second Amendment") that amends the Tax Asset Protection Plan dated May 5, 2017, as amended by the First Amendment to Tax Asset Protection Plan, dated April 6, 2018 (the “TAPP”) between the Company and the Rights Agent. The Second Amendment amends the definition of the “Final Expiration Date” under the TAPP to extend the duration of the TAPP and makes associated changes in connection therewith. At the Company's 2019 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, 2020.
Note 10 - 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") 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.

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

Spare parts include critical spares required to support plant operations. Parts and supply costs are determined using the lower of cost or estimated replacement cost. Parts are recorded as maintenance expenses in the period in which they are consumed.
Mine development costs include acquisition costs, the cost of other development work and mitigation costs related to the Company's mining operations which are depleted over the estimated life of the related mine reserves, which is 18 years. The Company performs an evaluation of the recoverability of the carrying value of mine development costs to determine if facts and circumstances indicate that their carrying value may be impaired and if any adjustment is warranted. There were no indicators of impairment as of June 30, 2019. Mine reclamation asset represents an asset retirement obligation asset and is depreciated over the estimated life of the mine, which is 18 years.
The Company holds a long-term investment (the "Highview Investment") in Highview Enterprises Limited ("Highview"), a London, England based developmental stage company specializing in power storage. In November 2014, the Company acquired an 8% ownership interest in the common stock of Highview for $2.8 million in cash. The Company accounts for the Highview Investment as an investment recorded at cost, less impairment, plus or minus observable changes in price for identical or similar investments of the same issuer.
The Highview Investment is evaluated for indicators of impairment such as an event or change in circumstances that may have a significant adverse effect on the fair value of the investment. There were no changes to the carrying value of the Highview Investment for the three and six months ended June 30, 2019 as there were no indicators of impairment or observable price changes for equity issued by Highview.

(10

The effective tax rate for the three and six months ended June 30, 2019 was different from the federal statutory rate primarily due to net increases of $4.8 million and $0.8 million during those periods, respectively, in the valuation allowance against deferred tax assets, and these changes were primarily a result of a change in forecasts of future taxable income as of June 30, 2019 in both the PGI and RC segments. In addition, the effective rate for both the three and six months ended June 30, 2019 was increased by state income tax expense, net of federal benefit.
The Company assesses the valuation allowance recorded against deferred tax assets at each reporting date. The determination of whether a valuation allowance for deferred tax assets is appropriate requires the evaluation of positive and negative evidence that can be objectively verified. Consideration must be given to all sources of taxable income available to realize the deferred tax asset, 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 13 - Business Segment Information
Operating segments are defined as components of an enterprise about which separate financial information is available that is evaluated regularly by a company's chief operating decision maker ("CODM"), or a decision-making group, in deciding how to allocate resources and in assessing financial performance. As of June 30, 2019, the Company's CODM was the Company's CEO. The Company's operating and reportable segments are identified by products and services provided.
As of June 30, 2019, the Company has two reportable segments: (1) Refined Coal ("RC"); and (2) Power Generation and Industrials ("PGI").
The business segment measurements provided to and evaluated by the CODM are computed in accordance with the principles listed below:
•
The accounting policies of the operating segments are the same as those described in the summary of significant accounting policies in the 2018 Form 10-K.
•
Segment revenues include equity method earnings and losses from the Company's equity method investments.
•
Segment operating income (loss) includes segment revenues and allocation of certain "Corporate general and administrative expenses," which include Payroll and benefits, Legal and professional fees and General and administrative.
•
RC segment operating income includes interest expense directly attributable to the RC segment.
As of June 30, 2019 and December 31, 2018, substantially all of the Company's material assets are located in the U.S. and all significant customers are U.S. companies. The following table presents the Company's operating segment results for the three and six months ended June 30, 2019 and 2018:

was unable to perform its obligations, the Company would be at risk regarding the amount of cash and investments in excess of the Federal Deposit Insurance Corporation limits (currently $250 thousand) that would be returned to the Company.
Assets and Liabilities Measured at Fair Value on a Recurring Basis
As of June 30, 2019 and December 31, 2018, the Company had no financial instruments carried and measured at fair value on a recurring basis.
Assets and Liabilities Measured at Fair Value on a Non-Recurring Basis
The Company completed the Carbon Solutions Acquisition, in which the fair value of the purchase consideration totaled $66.5 million. The Company's allocation of purchase consideration to the estimated fair values of the assets acquired and liabilities assumed is disclosed in Note 2.
The fair value measurements represent Level 3 measurements as they are based on significant inputs not observable in the market.
Note 15 - Restructuring
In December 2018, the Company recorded restructuring charges in connection with the departures of certain executives of Carbon Solutions in conjunction with the Carbon Solutions Acquisition. As part of the Carbon Solutions Acquisition, the Company also assumed a salary severance liability for an additional executive of Carbon Solutions in the amount of $0.6 million. Additionally, the Company recorded restructuring charges in 2018 in connection with a reduction in force that commenced in May 2018 as part of the Company's further alignment of the business with strategic objectives, which included the departure of certain executive officers. These charges related to cash severance arrangements with departing employees and executives, as well as stock-based compensation charges related to the acceleration of vesting of certain stock awards.

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations
The following discussion and analysis of the financial condition and results of our operations should be read together with the unaudited Condensed Consolidated Financial Statements and notes of Advanced Emissions Solutions, Inc. ("ADES" or the "Company") included elsewhere in Item 1 of Part I of this Quarterly Report and with the audited consolidated financial statements and the related notes of ADES included in the 2018 Form 10-K.
Overview
We provide environmental solutions to customers in coal-fired power generation, municipal water and other industries primarily through emissions and water purification control technologies of our subsidiaries and joint ventures. Our proprietary technologies and associated product offerings provide pollutant control solutions to enable coal-fired power generators, industrials and municipal water to reduce emissions of mercury and other air pollutants and to assist in the purification of water.
We operate two segments: Refined Coal ("RC") and Power Generation and Industrials ("PGI") (f/k/a "Emissions Control" or "EC"). Our RC segment is comprised of our equity ownership in Tinuum Group, LLC ("Tinuum Group"), an unconsolidated entity that provides reduction of mercury and nitrogen oxide ("NOX") emissions at select coal-fired power generators through the production and sale of RC that qualifies for tax credits under the Internal Revenue Code ("IRC") Section 45 - Production Tax Credit ("Section 45 tax credits"). We benefit from Tinuum Group's production and sale of RC, which generates tax credits, as well as the revenue from selling or leasing RC facilities to tax equity investors.
Our PGI segment includes the sale of products that provide mercury control and other air and water contaminants control to coal-fired power generators and other industrial companies. Our primary products are produced from lignite coal, which creates activated carbon ("AC"). From AC, we manufacture various forms of AC that include powdered activated carbon ("PAC") and granular activated carbon ("GAC"). There are three primary consumable products that work in conjunction with the installed equipment at coal-fired utilities to control mercury: PAC, coal additives and scrubber additives. In many cases these three consumable products can be used together or in many circumstances substituted for each other. However, activated carbon 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.
On December 7, 2018 (the "Acquisition Date"), we acquired (the "Carbon Solutions Acquisition") 100% of the equity interests of ADA Carbon Solutions, LLC (“Carbon Solutions”). Carbon Solutions is a manufacturer and seller of AC and a leader in mercury capture using PAC for the coal-fired power plant, industrial and water treatment markets. Carbon Solutions also owns an associated lignite mine that supplies the primary raw material for manufacturing powdered activated carbon. Carbon Solutions was formed in 2008 as a 50/50 joint venture by the Company and Energy Capital Partners LLC. The Company relinquished its ownership in 2011 as part of a legal settlement agreement as described in the Company's Annual Report on Form 10-K for the fiscal year ended December 31, 2017. The Company acquired Carbon Solutions primarily to expand the Company's product offerings within the mercury control industry and other complimentary PAC markets.
Results of Operations
For the three and six months ended June 30, 2019, we recognized net income of $8.1 million and $22.5 million compared to net income of $15.3 million and $23.0 million for the three and six months ended June 30, 2018.

The operating results for the three and six months ended June 30, 2019 are primarily attributable to a combination of factors, including:
•
Continued performance in our RC business segment, principally related to equity earnings and royalties from our Tinuum Group and Tinuum Services, LLC ("Tinuum Services") equity investments; and
•
Performance in our PGI business segment, principally related to the Carbon Solutions Acquisition.
The following sections provide additional information regarding these comparative periods. For comparability purposes, the following tables set forth our results of operations for the periods presented in the Condensed Consolidated Financial Statements included in Item 1 of this Quarterly Report. The period-to-period comparison of financial results may not be indicative of financial results to be achieved in future periods.

Consumables and consumables cost of revenue
For the three months ended June 30, 2019 and 2018, consumables revenues increased quarter over quarter primarily due to Carbon Solutions' operations. These operations also increased the total pounds of our consumables sold quarter over quarter.
Consumables cost of revenue was negatively impacted during 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 Carbon Solutions Acquisition. As of June 30, 2019, the step-up in inventory was fully recognized in cost of revenue for the three months ended June 30, 2019, and consumables gross margin will not be impacted for the remainder of 2019.
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. During the three months ended June 30, 2019, Consumables revenue and margins were negatively impacted by low coal-fired power dispatch driven by mild weather conditions as well as power generation from sources other than coal. In a recently updated forecast, the U.S. Energy Information Administration ("EIA") revised downward by 7% its December 2018 forecast for 2019 coal-fired electricity-generating units.
License royalties, related party
For the three months ended June 30, 2019 and 2018, there were 9.6 million tons and 8.2 million tons, respectively, of RC produced using M-45TM and M-45-PCTM technologies ("M-45 Technology"), which Tinuum Group licenses from us ("M-45 License"). The increase in license royalties was primarily due to Tinuum Group obtaining additional third-party investors for two new RC facilities, one each during the second and fourth quarters of 2018, as well as two additional RC facilities, one each during the first and second quarters of 2019, all of which use our M-45 License. The addition of these new invested RC facilities resulted in an increase in both payments to Tinuum Group and the related tons subject to the M-45 License.
Additional information related to revenue concentrations and contributions by class and reportable segment can be found within the Business Segments discussion and in Note 13 to the Condensed Consolidated Financial Statements.

Payroll and benefits
Payroll and benefits expenses, which represent costs related to selling, general and administrative personnel, increased during the three months ended June 30, 2019 compared to the same quarter in 2018 due to an increase in headcount of personnel resulting from the Carbon Solutions Acquisition. The quarter over quarter increase was partially offset due to restructuring expenses incurred in the three months ended June 30, 2018 of $0.9 million.

Legal and professional fees
Legal and professional fees increased during the three months ended June 30, 2019 compared to the same quarter in 2018 due to legal and professional services costs associated with the integration of Carbon Solutions as well as expenses incurred related to on-going matters in the normal course of business.
General and administrative
General and administrative expenses increased during the three months ended June 30, 2019 compared to the same quarter in 2018 due to an increase in general operating expenses, including increases in outsourced IT costs, travel, insurance and recruiting expenses. Further increases were for rent and occupancy expense due to additional leased office and warehouse space resulting from the Carbon Solutions Acquisition.
Depreciation, amortization, depletion and accretion
Depreciation and amortization expense increased during the three months ended June 30, 2019 compared to the same quarter in 2018 due to the addition of long-lived assets and intangible assets acquired as part of the Carbon Solutions Acquisition, which contributed approximately $0.5 million and $0.2 million of depreciation and amortization expense, respectively, for the three months ended June 30, 2019.

Earnings from equity method investments, and changes related thereto, are impacted by our most significant equity method investees: Tinuum Group and Tinuum Services. Earnings from equity method investments increased during the three months ended June 30, 2019 compared to the same quarter in 2018 primarily due to Tinuum Group completing a sale of an RC facility to a third-party investor during the three months ended June 30, 2019. Under Tinuum Group's revenue recognition policy pursuant to its adoption of ASU 2014-09 (Topic 606), Revenue from Contracts with Customers (“ASU 2014-09”) and ASU 2016-02, Leases (Topic 842), this sale was recognized at a point in time as opposed to over time under Tinuum's legacy revenue recognition policy.
During 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 of $19.2 million for the quarter. During the three months ended June 30, 2018, we recognized $14.5 million in equity earnings from Tinuum Group compared to our proportionate share of Tinuum Group's net income of $14.1 million for the quarter. The difference between our pro-rata share of Tinuum Group's net income and our earnings from our Tinuum Group equity method investment as reported on the Condensed Consolidated Statements of Operations for the three months ended June 30, 2018 is 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.
As of June 30, 2019 and 2018, Tinuum Group had 21 and 18 invested RC facilities, respectively, that were generating revenues. There were no 100% retained RC facilities as of June 30, 2019 or June 30, 2018, except for temporary operations of a retained RC facility prior to its lease or sale. Equity earnings from our interest in Tinuum Services increased by $0.3 million during the three months ended June 30, 2019 compared to the three months ended June 30, 2018, and for those quarters, Tinuum Services provided operating and maintenance services to 20 and 17 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.
We earned the following Section 45 tax credits related to the production of RC that may be available for future benefit:

$
1,888

The decrease in Section 45 tax credits earned during the three months ended June 30, 2019 compared to the three months ended June 30, 2018 was due to a decrease in production of RC related to our membership interest in GWN Manager, LLC ("GWN Manager") and Tinuum Group's partial ownership in a single RC facility that is generating tax credits.
Interest expense
For the three months ended June 30, 2019, interest expense increased $1.6 million compared to the three months ended June 30, 2018 primarily due to interest expense incurred in the three months ended June 30, 2019 of $1.6 million related to the Senior Term Loan entered into on December 7, 2018 to fund the Carbon Solutions Acquisition This increase was comprised of accrued interest on the Senior Term Loan principal in the amount of $1.1 million and interest expense related to debt discount and debt issuance costs associated with the Senior Term Loan of $0.5 million.
Income tax expense
For the three months ended June 30, 2019, we recorded income tax expense of $6.6 million compared to income tax benefit of $1.3 million for the three months ended June 30, 2018. 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. The income tax expense recorded for the three months ended June 30, 2018 was comprised of estimated federal income

31


tax benefit of $1.7 million and estimated state income tax expense of $0.4 million. The net increase in income tax expense quarter over quarter was primarily due to an increase in forecasted pre-tax income quarter over quarter as a result of the Carbon Solutions Acquisition and an increase in the valuation allowance on our deferred tax assets of $4.8 million for the three months ended June 30, 2019 compared to a decrease in the valuation allowance of $2.2 million for the three months ended June 30, 2018 based on changes in forecasts of future taxable income for both quarters in both the PGI and RC segments.

Consumables and consumables cost of revenue
During the six months ended June 30, 2019 and 2018, consumables revenues increased period over period primarily due to Carbon Solutions' operations. These operations also increased the total pounds of our consumables sold period over period.
Consumables cost of revenue was negatively impacted during the 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 Carbon Solutions Acquisition. As of June 30, 2019, a step-up in inventory was fully recognized in cost of revenue for the six months ended June 30, 2019, and consumables gross margin will not be impacted for the remainder of 2019.
During the six months ended June 30, 2019, Consumables revenue and margins were negatively impacted by low coal-fired power dispatch driven by mild weather conditions as well as power generation from sources other than coal. In a recently updated forecast, the EIA revised downward by 7% its December 2018 forecast for 2019 coal-fired electricity-generating units.

License royalties, related party
During the six months ended June 30, 2019 and 2018, there were 20.5 million tons and 15.9 million tons, respectively, of RC produced using the M-45 Technology under the M-45 License. The increase in license royalties was primarily due to obtaining additional third-party investors for two new RC facilities during 2018 and two new RC facilities during the first half of 2019, all of which use our M-45 License. The addition of these new invested RC facilities resulted in an increase in both cash payments to Tinuum Group and the related tons subject to the M-45 License.

Earnings from equity method investments, and changes related thereto, are impacted by our most significant equity method investees: Tinuum Group and Tinuum Services. Earnings from equity method investments increased during the six months ended June 30, 2019 compared to the same period in 2018 primarily due to Tinuum Group completing the sale of two RC facilities to a third-party investor during the six months ended June 30, 2019.
The carrying value of our investment in Tinuum Group was $42.5 million as of June 30, 2019, as our cumulative pro-rata share of Tinuum Group's income for the six months ended June 30, 2019 exceeded the amount of the cumulative cash distributions as a result of Tinuum Group's adoption of ASU 2014-09 and ASU 2016-02 as of January 1, 2019, in which we recorded a cumulative adjustment of $28.8 million related to our percentage of Tinuum Group's cumulative effect adjustment that increased our retained earnings as of January 1, 2019. As part of this adjustment, we increased the carrying value of our investment in Tinuum Group by $37.2 million. Throughout 2018, we recognized equity earnings from Tinuum Group to the extent that cash distributions were received from Tinuum Group during the period. See additional information related to our investment balance, equity earnings (losses) and cash distributions in Note 4 of the Condensed Consolidated Financial Statements.

For the six months ended June 30, 2019, we recognized $39.0 million in equity earnings from Tinuum Group compared to our proportionate share of Tinuum Group's net income of $40.7 million for the period. The difference represents the cumulative earnings short-fall balance as of the end of the immediately preceding period, which was December 31, 2018. For the six months ended June 30, 2018, we recognized $25.5 million in equity earnings from Tinuum Group compared to our proportionate share of Tinuum Group's net income of $26.5 million for the period. This difference is 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.

Equity earnings from our interest in Tinuum Services increased during the six months ended June 30, 2019 compared to the six months ended June 30, 2018. During the six months ended June 30, 2019 and 2018, Tinuum Services provided operating and maintenance services to 20 and 17 operating RC facilities, respectively, which was the driver in the increase in equity earnings. Tinuum Services derives earnings under fixed-fee arrangements as well as fee arrangements that are based on actual RC production, depending upon the specific RC facility operating and maintenance agreement.

We earned the following Section 45 tax credits related to the production of RC that may be available for future benefit:

$
3,618


The decrease in Section 45 tax credits earned during the six months ended June 30, 2019 compared to the six months ended June 30, 2018 was due to a decrease in production of RC related to our membership interest in GWN Manager and Tinuum Group's ownership in a single RC facility that is generating tax credits.
Interest expense
For the six months ended June 30, 2019, interest expense increased $3.3 million compared to the six months ended June 30, 2018 primarily due to interest expense incurred in the six months ended June 30, 2019 related to the Senior Term Loan entered into on December 7, 2018 to fund the Carbon Solutions Acquisition. The increase was comprised of accrued interest on the Senior Term Loan principal in the amount of $2.4 million and interest expense related to debt discount and debt issuance costs associated with the Senior Term Loan of $0.9 million.
Income tax expense
For the six months ended June 30, 2019, we recorded income tax expense of $8.3 million compared to income tax expense of $1.2 million for the six months ended June 30, 2018. 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. The net increase in income tax expense period over period was primarily due to an increase in forecasted pre-tax income period over period as a result of the Carbon Solutions Acquisition and an increase in the valuation allowance on our deferred tax assets of $0.8 million for the six months ended June 30, 2019 compared to a decrease in the valuation allowance of $0.5 million for the six months ended June 30, 2018 based on changes in forecasts of future taxable income for both periods in both the PGI and RC segments.

Non-GAAP Financial Measures

34


To supplement the Company's financial information presented in accordance with U.S. generally accepted accounting principles, or GAAP, we are providing non-GAAP measures of certain financial performance. These non-GAAP measures include Consolidated EBITDA and Segment EBITDA. The Company included non-GAAP measures because management believes that they help to facilitate comparison of operating results between periods. The Company believes the non-GAAP measures provide useful information to both management and users of the financial statements by excluding certain expenses, gains and losses that may not be indicative of core operating results and business outlook. These non-GAAP measures are not in accordance with, or an alternative to, measures prepared in accordance with GAAP and may be different from non-GAAP measures used by other companies. In addition, these non-GAAP measures are not based on any comprehensive set of accounting rules or principles. These measures should only be used to evaluate the Company's results of operations in conjunction with the corresponding GAAP measures.
The Company has defined Consolidated EBITDA as net income, adjusted for the impact of the following items that are either non-cash or that the Company does not consider representative of its ongoing operating performance: depreciation, amortization, depletion and accretion, interest expense, net and income tax expense. Because Consolidated EBITDA omits certain non-cash items, the Company believes that the measure is less susceptible to variances that affect the Company's operating performance.
Segment EBITDA is calculated as Segment operating income (loss) adjusted for the impact of the following items that are either non-cash or that the Company does not consider representative of its ongoing operating performance: depreciation, amortization, depletion and accretion and interest expense, net. When used in conjunction with GAAP financial measures, Segment EBITDA is a supplemental measure of operating performance that management believes is a useful measure related the Company's PGI segment performance relative to the performance of its competitors as well as performance period over period. Additionally, the Company believes the measure is less susceptible to variances that affect its operating performance results.
The Company presents Consolidated EBITDA and Segment EBITDA because the Company believes they are useful as supplemental measures in evaluating the performance of the Company's operating performance and provide greater transparency into the results of operations. The Company's management uses Consolidated EBITDA and Segment EBITDA as factors in evaluating the performance of its business.
The adjustments to Consolidated EBITDA and Segment EBITDA in future periods are generally expected to be similar. Consolidated EBITDA and Segment EBITDA have limitations as analytical tools, and these measures should not be considered in isolation or as a substitute for analyzing the Company's results as reported under GAAP.

During the three months ended June 30, 2019, Consolidated EBITDA was $17.4 million, an increase of $3.0 million over the second quarter of 2018, driven by higher expenses related to interest expense, net, depreciation, amortization, depletion and accretion, and income tax expense.
During the six months ended June 30, 2019, Consolidated EBITDA was $37.7 million, an increase of $12.6 million over the comparable period during 2018, driven by higher expenses related to interest expense, net, depreciation, amortization, depletion and accretion, and income tax expense.

Business Segments
As of June 30, 2019, 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:

35


•
The accounting policies of the operating segments are the same as those described in the summary of significant accounting policies in the 2018 Form 10-K.
•
Segment revenues include equity method earnings and losses from our equity method investments.
•
Segment operating income (loss) includes segment revenues and allocation of certain "Corporate general and administrative expenses," which include Payroll and benefits, Rent and occupancy, Legal and professional fees, and General and administrative.
•
RC segment operating income includes interest expense directly attributable to the RC segment.
The principal products and services of our segments are:
1.
RC - Our RC segment derives its earnings from equity method investments as well as royalty payment streams and other revenues related to enhanced combustion of and reduced emissions of both NOX and mercury from the burning of coal. Our equity method investments related to the RC segment include Tinuum Group, Tinuum Services and other immaterial equity method investments. Segment revenues include our equity method earnings (losses) from our equity method investments and royalty earnings from Tinuum Group. These earnings are included within the Earnings from equity method investments and License royalties, related party line items in the Condensed Consolidated Statements of Operations. Key drivers to the RC segment performance are the produced and sold RC from both operating and retained RC facilities, royalty-bearing tonnage and the number of operating (leased or sold) and retained RC facilities. These key drivers impact our earnings and cash distributions from equity method investments.
2.
PGI - Our PGI segment primarily includes revenues and related expenses from the sale of consumable products that utilize PAC chemical technologies. These options provide coal-powered utilities and industrial boilers with mercury control solutions working in conjunction with activated carbon injection ("ACI") and dry sorbent injection ("DSI") systems and other pollution control equipment, generally without the requirement for significant ongoing capital outlays. These amounts are included within the respective revenues and cost of revenue line items in the Condensed Consolidated Statements of Operations.
Management uses segment operating income (loss) to measure profitability and performance at the segment level. Management believes segment operating income (loss) provides investors with a useful measure of our operating performance and underlying trends of the businesses. Segment operating income (loss) may not be indicative of our overall consolidated performance and therefore, should be read in conjunction with our Condensed Consolidated Statements of Operations.

For the three months ended June 30, 2019 and June 30, 2018
RC earnings increased primarily due to an increase in equity earnings in Tinuum Group during the three months ended June 30, 2019 compared to the same quarter in 2018, as presented above. Our equity earnings increased primarily due to completing a sale of an RC facility to a third-party investor during three months ended June 30, 2019, which was recognized in Tinuum earnings during the period. As a result of accounting standards adopted by Tinuum Group on January 1, 2019, which resulted in an increase in our investment in Tinuum Group, we recognized our proportionate share of earnings as reported by Tinuum Group beginning on January 1, 2019, as we had earnings in excess of cumulative distributions.


37


Earnings from Tinuum Services for the three months ended June 30, 2019 increased compared to the same quarter in 2018 primarily due to an increase in the number of operating RC facilities from 17 to 20 in which Tinuum Services provides operating and maintenance services.
RC earnings were positively impacted during the three months ended June 30, 2019 by an increase in royalties related to Tinuum Group's use of our M-45 License. During the three months ended June 30, 2019 and 2018, there were 9.6 million tons and 8.2 million tons, respectively, of RC produced using the M-45 Technology. The increase in Royalty revenue was driven by both an increase in payments to Tinuum Group and the related tons subject to the M-45 License.
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 4 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, 2019 and June 30, 2018
PGI segment operating loss increased during the three months ended June 30, 2019 compared to the three months ended June 30, 2018 primarily due to an additional $1.3 million of cost of revenue expense related to a step-up in basis of acquired finished goods inventory and $0.6 million of depreciation, amortization and depletion expense related to the Carbon Solutions Acquisition. During the three months ended June 30, 2019, Consumables revenue and margins were negatively impacted by low coal-fired power dispatch driven by milder weather conditions as well as power generation from sources other than coal. In a recently updated forecast, the EIA revised downward by 7% its December 2018 forecast for 2019 coal-fired electricity-generating units.

PGI Segment EBITDA loss was $3.1 million, inclusive of a $1.3 million adjustment to cost of revenue due to the step-up in basis of inventory acquired related to the Carbon Solutions Acquisition. PGI Segment EBITDA loss increased by $1.8 million over the first quarter of 2018, mostly driven by an increase in segment operating loss of $2.5 million, which was offset by additional depreciation, amortization, depletion and accretion expense of $0.6 million related to assets acquired from the Carbon Solutions Acquisition.
RC
For the six months ended June 30, 2019 and June 30, 2018
RC earnings increased primarily due to an increase in equity earnings in Tinuum Group during the six months ended June 30, 2019 compared to the same period in 2018, as presented above. Our equity earnings increased primarily due to an increase in cash distributions from Tinuum Group due to the addition of four invested facilities, two who were invested in 2018 and two invested in during the six months ended June 30, 2019. For the six months ended June 30, 2019, our share of equity earnings from Tinuum Group increased $13.5 million from the comparable period in 2018 due to an increase in lease revenues driven by significant sales of facilities to third-party investors. Distributions received from Tinuum Group for the six months ended June 30, 2018 were recorded directly to earnings, as our investment was in a memorandum account as discussed in Note 4. 

Earnings from Tinuum Services for the six months ended June 30, 2019 increased compared to the same period in 2018 primarily due to an increase in the number of operating RC facilities from 17 to 20 in which Tinuum Services provides operating and maintenance services.
RC earnings were positively impacted during the six months ended June 30, 2019 by an increase in royalties related to Tinuum Group's use of our M-45 License. During the six months ended June 30, 2019 and 2018, there were 20.5 million tons and 15.9

38


million tons, respectively, of RC produced using the M-45 Technology. The increase in Royalty revenue was driven by an increase in both payments to Tinuum Group and the related tons subject to the M-45 License.
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.
Additional discussion of our equity method investments is included above within our consolidated results and in Note 4 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.

PGI segment operating income decreased during the six months ended June 30, 2019 compared to the six months ended June 30, 2018 primarily due to the increase in operating income due to the operations of Carbon Solutions. This increase is offset with an additional $4.7 million of cost of revenue expense related to a step-up in basis of acquired finished goods inventory and $2.6 million of depreciation, amortization, and depletion expense related to Carbon Solutions Acquisition. In a recently updated forecast, the EIA revised downward by 7% its December 2018 forecast of 2019 coal-fired electricity-generating units.

Liquidity and Capital Resources
Overview of Factors Affecting Our Liquidity
During the six months ended June 30, 2019, our liquidity position was positively affected primarily due to distributions from Tinuum Group and Tinuum Services, royalty payments from Tinuum Group and borrowing availability under our bank ("Lender") line of credit ("Line of Credit").
Our principal sources of cash include:
•
cash on hand;
•
distributions from Tinuum Group and Tinuum Services;
•
royalty payments from Tinuum Group; and
•
operations of the PGI segment.
Our principal uses of cash during the six months ended June 30, 2019 included:
•
repurchases of shares of common stock;
•
payment of dividends;
•
payment of debt principal and interest;
•
our business operating expenses, including federal and state tax payments and cash severance payments; and
•
delivering on our existing contracts and customer commitments.
Our ability to continue to generate sufficient cash flow required to meet ongoing operational needs and obligations, as well as
future expected dividend payments and potential future share repurchases, depends upon several factors, including executing on
our contracts and initiatives, receiving royalty payments from Tinuum Group and distributions from Tinuum Group and Tinuum
Services, and increasing our share of the market for PGI consumables, as well as expanding our overall PAC business into
additional adjacent markets. Increased distributions from Tinuum Group will likely be dependent upon both preserving existing
contractual relationships and the securing of additional tax equity investors for those Tinuum Group facilities that are currently not operating.
Due to the Carbon Solutions Acquisition, we expect our use of liquidity for capital expenditures will increase in future periods. Carbon Solutions has historically incurred costs for capital expenditures related to its PAC manufacturing facility, under normal operations and planned outages, and for mine development at its lignite mine. Going forward, we anticipate additional material capital resources will be needed to maintain or improve capital assets. We incurred expenditures related to planned maintenance on our manufacturing facility during the three months ended June 30, 2019.

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, 2019 and 2018:

Future cash flows from Tinuum through 2021 are expected to range from $175 to $200 million, and key drivers in achieving
these future cash flows are based on the following:

•
21 invested facilities as of June 30, 2019 and inclusive of all net Tinuum cash flows (distributions and license
royalties), offset by estimated federal and state income tax payments and 453A interest payments.

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

•
Tinuum Group continues to not operate retained facilities;
•
Tinuum Group does not have material unexpected capital expenditures or unusual operating expenses;
•
Tax equity lease renewals on invested facilities are not terminated or repriced; and
•
Coal-fired power generation remains consistent.
Future incremental invested RC facilities would positively impact our expectation of future cash flows.

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 Carbon Solutions Acquisition as disclosed in Note 2. We also paid debt issuance costs of $2.0 million related to the Senior Term Loan. The Senior Term Loan has a term of 36 months and bears interest at a rate equal to 3-month LIBOR (subject to a 1.5% floor) + 4.75% per annum, which is adjusted quarterly to the current 3-month LIBOR rate, and interest is payable quarterly in arrears. Quarterly principal payments of $6.0 million are required and commenced in March 2019, and we may prepay the Senior Term Loan at any time without penalty. The Senior Term Loan is secured by substantially all of our assets, including the cash flows from Tinuum Group and Tinuum Services (collectively, the "Tinuum Entities"), but excluding our equity interests in those Tinuum entities. During the six months ended June 30, 2019, we made principal loan payments of $16.0 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.
Stock Repurchases and Dividends
In November 2018, the Board of Directors (the "Board") authorized us to purchase up to $20.0 million of our outstanding common stock. This stock repurchase program will remain in effect until December 31, 2019 unless otherwise modified by the Board. Previously, in December 2017, the Board had authorized us to purchase up to $20.0 million of our outstanding common stock under a separate repurchase program that was in effect until July 31, 2018. During the year ended December 31, 2018, under these two stock repurchase programs, we purchased 2,350,422 shares of our common stock for cash of $25.3 million, inclusive of commissions and fees. During the six months ended June 30, 2019, under the applicable stock repurchase program, we purchased 248,591 shares of our common stock for cash of $2.8 million, inclusive of commissions and fees.
During the six months ended June 30, 2019 and 2018, we declared and paid quarterly cash dividends to stockholders of $9.2 million and $10.2 million, respectively, as follows:

Line of Credit
As of June 30, 2019, there were no outstanding borrowings under the Line of Credit.
On September 30, 2018, ADA, as borrower, we, as guarantor, and the Lender entered into an amendment (the "Twelfth Amendment") to the Line of Credit. The Twelfth Amendment decreased the borrowing availability of the Line of Credit to $5.0 million due to decreased collateral requirements, extended the maturity date of the Line of Credit to September 30, 2020 and permitted the Line of Credit to be used as collateral (in place of restricted cash) for letters of credit ("LC's") up to $5.0 million related to equipment projects and certain other agreements. Under the Twelfth Amendment, there was no minimum balance requirement based on us meeting certain conditions and maintaining minimum trailing twelve-month EBITDA (earnings before interest, taxes, depreciation and amortization), as previously defined in the "Eleventh Amendment" to the Line of Credit, of $24.0 million.
On December 7, 2018, ADA, as borrower, we, as guarantor, and the Lender entered into an amendment to the Line of
Credit, which provided, among other things, for ADA to be able to enter into the Senior Term Loan as a guarantor so long as
the principal amount of the Senior Term Loan does not exceed $70.0 million. Additionally, the financial covenants in the Line

41


of Credit were amended and restated to be consistent with the aforementioned Senior Term Loan covenants, including
maintaining a minimum cash balance of $5.0 million.

Cash flow from operating activities
Cash flows provided by operating activities for the six months ended June 30, 2019 were $30.6 million and changed by $34.0 million compared to the six months ended June 30, 2018. Cash flows from operating activities were positively impacted primarily by the following: (1) net income of $22.5 million, which was primarily due to earnings from equity method investees of $42.6 million and license royalties earned from Tinuum Group of $8.4 million; (2) distributions from equity method investees, return on investment of $38.1 million; (3) a decrease in deferred tax assets, exclusive of valuation allowance changes, of $4.1 million; (4) depreciation, amortization, depletion, and accretion of $2.9 million; and a net decrease in working capital of $3.2 million. Included in distributions from equity method investees, return on investments is $33.8 million of distributions received from Tinuum Group. During the six months ended June 30, 2018, the carrying value of our investment in Tinuum Group was zero and all cash distributions were reported as distributions in excess of cumulative earnings, which is reported as cash flows from investing activities. Due to the increase in the balance of our investment in Tinuum Group during the six months ended June 30, 2019, all distributions during the period were reported as return on investment. Offsetting these increases to operating cash flows were earnings from equity method investees of $42.6 million.

Cash flows used in operating activities for the six months ended June 30, 2018 were $3.4 million and were positively impacted primarily by the following: (1) net income of $23.0 million, which was primarily due to earnings from equity method investees of $28.1 million and license royalties earned from Tinuum Group of $6.8 million; (2) distributions from equity method investees, return on investment of $2.7 million; and (3) stock-based compensation of $1.0 million. Offsetting these increases to operating cash flows were primarily earnings from equity method investees of $28.1 million and a net increase in working capital of $1.5 million.

Cash flow from investing activities
Distributions from equity method investees
Distributions received from our equity method investees reported as return in excess of investment basis within investing cash flows decreased by $25.5 million for the six months ended June 30, 2019 compared to the six months ended June 30, 2018. The decrease was driven primarily by the effect of an increase in our equity investment in Tinuum Group, which resulted in all cash distributions reported as return on investment during the six months ended June 30, 2019. In total, cash distributions from Tinuum Group increased quarter over quarter due to additional invested RC facilities in the second half of 2018 and first half of 2019.

These expenditures approximated $3.8 million during the six months ended June 30, 2019.
