Advanced Emissions Solutions, Inc. ("ADES" or the "Company") is a Delaware corporation with its principal office located in Greenwood Village, Colorado and manufacturing, mining and logistics operations located in Louisiana. The Company is principally engaged in the sale of consumable air and water treatment solutions including activated carbon ("AC") and chemical technologies. The Company's proprietary technologies in the advanced purification technologies ("APT") market enable customers to reduce air and water contaminants, including mercury and other pollutants, to maximize utilization levels and to improve operating efficiencies to meet the challenges of existing and pending air quality and water regulations. The Company manufactures and sells AC and other chemicals used to capture and remove contaminants for coal-fired power, industrial and water treatment markets. The Company also owns an associated lignite mine ("Five Forks Mine") which supplies the primary raw material for manufacturing AC.

Through December 31, 2021, the Company generated substantial earnings from its equity ownership in Tinuum Group, LLC ("Tinuum Group") and Tinuum Services, LLC ("Tinuum Services"), both of which are unconsolidated entities. Both Tinuum Group and Tinuum Services ceased material operations effective December 31, 2021 as a result of the expiration of a tax credit program under Internal Revenue Code Section 45 - Production Tax Credit (the "Section 45 Tax Credit Program"). Tinuum Group provided reduction of mercury and nitrogen oxide ("NOx") emissions at select coal-fired power generators through the production and sale of refined coal ("RC") that qualified for tax credits under the Section 45 Tax Credit Program ("Section 45 tax credits"). The Company also earned royalties for technologies which were licensed to Tinuum Group and used at certain RC facilities to enhance combustion and reduce emissions of NOx and mercury from coal burned to generate electrical power. Tinuum Services operated and maintained the RC facilities under operating and maintenance agreements with Tinuum Group and owners or lessees of the RC facilities. Presently, both Tinuum Group and Tinuum Services continue to wind-down their operations, and the Company expectshas received what it anticipates to receivebe final cash distributions which are not expected to be significant, from these entities during 2022.entities.

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 and Tinuum Services, which are accounted for under the equity method of accounting, and Highview Enterprises Limited (the "Highview Investment"), which is accounted for in accordance with U.S. GAAP applicable to equity investments that do not qualify for the equity method of accounting.

Results of operations and cash flows for the interim periods are not necessarily indicative of the results that may be expected for the entire year. All significant intercompany transactions and accounts were eliminated in consolidation for all periods presented in this Quarterly Report.

In the opinion of management, these Condensed Consolidated Financial Statements include all normal and recurring adjustments considered necessary for a fair presentation of the results of operations, financial position, stockholders' equity and cash flows for the interim periods presented. These Condensed Consolidated Financial Statements should be read in conjunction with the Company’s Annual Report on Form 10-K for the year ended December 31, 2021 (the "2021 Form 10-K"). Significant accounting policies disclosed therein have not changed.

Basic earnings (loss) per share is computed using the weighted-average number of shares of common stock outstanding during

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

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 2021 Form 10-K. Actual results could differ from these estimates.

The loss of earnings and cash distributions from both Tinuum Group and Tinuum Services will continue to have a material adverse impact on the Company’s financial position, results of operations and cash flows. For 2022, the Company is principally dependent on operations of its APT business and its cash on hand to provide liquidity over the near and long term. The Company's revenues, sales volumes, earnings and cash flows are significantly affected by prices of competing power generation sources such as natural gas and renewable energy. During periods of low natural gas prices, natural gas provides a competitive alternative to coal-fired power generation and therefore, coal consumption may be reduced, which in turn reduces the demand for the Company's products. However, during periods of higher prices for competing power generation sources, there is an increase in coal consumption and thus demand for the Company's products also increases.

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

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

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

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

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

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 JuneSeptember 30, 2022, the Company's CODM was the Company's Chief Executive Officer, and the Company concluded that APT was its 1one reportable segment.

Given the wind-down of Tinuum Group and Tinuum Services and the impact on the Company's financial statements, the Company determined the historical RC segment no longer met the qualitative or quantitative criteria to be considered a reporting segment under U.S. GAAP. As a result, including the method in which the CODM allocates resources, beginning January 1, 2022, the Company determined that it had 1one reportable segment and therefore has removed its segment disclosures for this Quarterly Report.

On September 30, 2020, the Company and Norit Activated Carbon - Americas (f/k/a Cabot Norit Americas, Inc.) ("Norit"), entered into a supply agreement (the "Supply Agreement") pursuant to which the Company agreed to sell and deliver to Norit, and Norit agreed to purchase and accept from the Company certain lignite-based AC products ("Furnace Products"). The term of the Supply Agreement is for 15 years with 10-year renewal terms that are automatic unless either party provides three years prior notice of intention not to renew before the end of any term.

Further, under the terms of the Supply Agreement, Norit was obligated to pay the Reclamation Reimbursement (defined in Note 34 below) to the Company for $10.2 million of the Reclamation Costs (defined in Note 34 below), inclusive of interest. The Company recorded the Norit Receivable for the Reclamation Reimbursement at its estimated fair value, which was measured using a discounted cash flows valuation model that considered the estimated credit risk associated with the obligor's (Norit's) future performance, which the Company estimated was approximately 1.5%.

On February 25, 2022, the Company received $10.6 million in cash from Norit (the "Norit Payment") as a result of a change in control provision in the Supply Agreement (the "Change in Control"), which occurred as a result of the sale of Norit by its parent, Cabot Corporation. Under the Change in Control, the Company received from Norit full payment of all amounts outstanding under the Reclamation Reimbursement, payment of all unbilled amounts related to Specific Capital for expenditures incurred through February 28, 2022 and payment of $0.8 million related to additional costs due to the third-party operator of Marshall Mine (the "Norit Reclamation Costs"). Under the Reclamation Contract (defined in Note 34 below), the Company was obligated to remit payment for the Norit Reclamation Costs to the third-party operator of Marshall Mine (defined in Note 4 below), and such payment was remitted in March 2022. The Change in Control did not impact any other provisions of the Supply Agreement.

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

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

Concurrently with the execution of the Supply Agreement, on September 30, 2020, the Company entered into an agreement to purchase from Norit 100% of the membership interests in Marshall Mine, LLC (the "Marshall Mine Acquisition") for a nominal cash purchase price. Marshall Mine, LLC owns a lignite mine located outside of Marshall, Texas (the "Marshall Mine"). The Company concluded that the Marshall Mine did not have any remaining economic reserves and independently determined to immediately commence activities to shutter it. Accordingly, on September 30, 2020, the Company and a third party entered into a reclamation contract (the "Reclamation Contract") for full reclamation of the Marshall Mine, which iswas expected to be completed by 2030. Under the terms of the Supply Agreement, Norit was obligated to reimburse the Company for $10.2 million (the "Reclamation Reimbursement") for a portion of the total costs incurred under the Reclamation Contract (the "Reclamation Costs"), which was payable semi-annually over 13 years and inclusive of interest. As discussed in Note 2,3, on February 25, 2022 as part of the Change in Control, Norit fully paid the outstanding amount owed under the Reclamation Reimbursement and has no further liability related to the Marshall Mine.

The Company accounted for the Marshall Mine Acquisition as an asset acquisition, and it included the acquisition of certain assets and assumption of certain liabilities as well as the incurrence of an obligation for the Reclamation Costs (the "Marshall Mine ARO"). As of JuneSeptember 30, 2022 and December 31, 2021, the carrying value of the Marshall Mine ARO was $4.8$4.6 million and $6.3 million, respectively.

As the Marshall Mine Acquisition represented a transaction with a customer of net assets acquired and liabilities assumed from Norit, the Company accounted for the excess of the fair value of liabilities assumed over assets acquired as upfront consideration transferred to a customer, Norit (the "Upfront Customer Consideration"). The amount of the Upfront Customer Consideration was also recognized net of the Reclamation Reimbursement. The total Upfront Customer Consideration is being amortized as a reduction to revenues on a straight-line basis over the expected 15-year contractual period of the Supply Agreement. Amortization of the Upfront Customer Consideration is approximately $0.5 million per year.

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 - 45 days 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.

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 "Other current liabilities" in the Consolidated Balance Sheets and, if deliverable outside of one year, is included in "Other long-term liabilities" in the Consolidated Balance Sheets.

The following table shows the components of the Company's Receivables, net:

For the three and sixnine months ended JuneSeptember 30, 2022 and 2021, all material performance obligations related to revenues recognized were satisfied at a point in time. For the three and sixnine months ended JuneSeptember 30, 2022, approximately 8%7% and 9%, respectively, of Consumables revenues were generated in Canada, and all other revenues were generated in the U.S. For the three and sixnine months ended JuneSeptember 30, 2021, approximately 10%8% and 15%12%, respectively, of Consumables revenues were generated in Canada, and all other revenues were generated in the U.S.

The following table summarizes the Company's inventories recorded at the lower of average cost or net realizable value, as of JuneSeptember 30, 2022 and December 31, 2021:

On May 4, 2022, the Compensation Committee of the Board of Directors and the Board of Directors (the "Board") approved the amendment to retention agreements (the "Retention Agreements" and each a "Retention Agreement"), which had been executed in May 2021, between the Company and its executive officers and certain other key employees in order to maintain the Company's business operations while it pursues and executes on its strategic initiatives (the "Amended Retention Agreements"). Under the Amended Retention Agreements, employees will receive (i) 40% of the original amount agreed to in the Retention Agreements ("Retention Pay") in August 2022; (ii) 60% of the Retention Pay on the earliest of (1) the date the employee’s employment is terminated without Cause or for Good Reason (as those terms are defined in the Retention Agreement or the employee’s employment agreement, as applicable), (2) 90 days after a Transaction Date or a Change in Control (as those terms are defined in the Retention Agreement or the employee’s employment agreement, as applicable), or (3) in January 18, 2023; and (iii) an additional lump sum payment, ranging from 10% to 40% of the Retention Pay, will also be paid at the earliest of (1) the date the employee’s employment is terminated without Cause or for Good Reason (as those terms are defined in the Retention Agreement or the employee’s employment agreement, as applicable), (2) 90 days after a Transaction Date or a Change in Control (as those terms are defined in the Retention Agreement or the employee’s employment agreement, as applicable), or (3) in January 2023.

In order to receive the Amended Retention Agreements payments, employees must remain employed at the Company through the dates above. In August 2022, the Company paid out $1.0 million pursuant to the payment terms of the Amended Retention Agreements. As of JuneSeptember 30, 2022, the total cash payable pursuant to the Amended Retention Agreements is $2.5$1.1 million and is included in the "Other current liabilities" line item in the Condensed Consolidated Balance Sheet.

As the owner of the Marshall Mine, the Company is required to post a surety bond with a regulatory commission. As of JuneSeptember 30, 2022 and December 31, 2021, the Company had posted a $16.6 million surety bond (the "MM Surety Bond") which will remain in place until the Marshall Mine is fully reclaimed, and may be further reduced in amount from time to time as the Company progresses with its reclamation activities.

As of JuneSeptember 30, 2022 and December 31, 2021, the Company posted cash collateral of $10.0 million for both the Marshall Mine and Five Forks Mine as required by the Company's surety bond provider, which is reported as long-term restricted cash on the Condensed Consolidated Balance Sheets.

The Company has certain limited obligations contingent upon future events in connection with the activities of Tinuum Group. The Company, NexGen Refined Coal, LLC ("NexGen") and 2two 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 committed by Tinuum Group. The Company also is a party to a contribution agreement with NexGen under which any party called upon to pay on a Tinuum Group Party Guaranty is entitled to receive contributions from the other party equal to 50% of the amount paid. The Company has not recorded a liability or expense provision related to this contingent obligation as it believes that it is not probable that a loss will occur with respect to the Tinuum Group Party Guaranties.

The Company is from time to time subject to various pending or threatened legal actions and proceedings, including those that arise in the ordinary course of its business. Such matters are subject to many uncertainties and outcomes, the financial impacts of which are not predictable with assurance and that may not be known for extended periods of time. The Company records a liability in its consolidated financial statements for costs related to claims, settlements and judgments where management has assessed that a loss is probable and an amount can be reasonably estimated. There were no significant legal proceedings as of JuneSeptember 30, 2022.
