Note 1 - Basis of Presentation
Nature of Operations
Advanced Emissions Solutions, Inc. ("ADES" or the "Company") is a Delaware corporation with its principal office located in Greenwood Village, Colorado, manufacturing and logistics operations located in Louisiana and a manufacturing facility in Kentucky. The Company is an environmental technology company and has been 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 generation, industrial and water treatment markets. The Company also owns an associated lignite mine ("Five Forks Mine") that currently supplies the primary raw material for manufacturing AC.
Acquisition
On February 1, 2023 (the "Acquisition Date"), the Company entered into a Securities Purchase Agreement (the "Purchase Agreement") with Arq Limited ("Arq Ltd."), a company incorporated under the laws of Jersey, pursuant to which the Company acquired all of the direct and indirect equity interests of Arq Ltd.'s subsidiaries (the "Arq Acquisition," and hereafter referred to as "Arq") in exchange for consideration (the "Purchase Consideration") totaling $31.2 million, and consisting of (i) 3,814,864 shares of the Company's common stock, par value $0.001 per share (the "Common Stock") and (ii) 5,294,462 shares (the "Preferred Shares") of the Company's Series A Convertible Preferred Stock, par value $0.001 per share (the "Series A Preferred Stock").
Arq's principal office is located in London, United Kingdom with an additional office located in Corbin, Kentucky near its production facility ("the Corbin Facility"). The Corbin location consists of bituminous coal reserves and a manufacturing facility to recover and purify the bituminous coal fines for sale or further conversion to value-added specialty chemicals. Arq is a pre-revenue, environmental technology company that has developed a process for transforming coal waste into a purified, microfine carbon powder, known as Arq powderTM ("Arq Powder"). The Company expects to begin using Arq Powder to produce granular activated carbon ("GAC") products in the second half of 2024.
See further discussion of the Arq Acquisition in Note 2.
Loan Agreement
As required under the Purchase Agreement, and on February 1, 2023 (the "Closing Date"), the Company, as borrower, certain of its subsidiaries, as guarantors, and CF Global ("CFG"), a related party, as administrative agent and lender (the "Lender"), entered into a term loan (the "Term Loan") in the amount of $10.0 million, less original issue discount ("OID") of $0.2 million, upon execution of a Term Loan and Security Agreement (the "Loan Agreement"). The Company received net cash proceeds of $8.5 million after deducting the OID and debt issuance costs of $1.3 million.
The Loan Agreement also provides for the issuance of a warrant (the "Warrant") to CFG to purchase 325,457 shares of Common Stock (the "Warrant Shares"), which represents 1% of the post-Arq Acquisition and PIPE Investment (as defined below) fully diluted share capital (as defined in the Loan Agreement), at an exercise price of $0.01 per share. The Warrant has a term of 7 years and contains a cashless exercise provision.
See further discussion of the Term Loan in Note 6.
Equity Financing
On February 1, 2023, the Company entered into Subscription Agreements (the "Subscription Agreements") with certain persons (the "Subscribers"), which included existing shareholders of Arq Ltd., three of which were appointed to the Company's Board of Directors (the "Board"), pursuant to which the Subscribers subscribed for and purchased shares of Common Stock for an aggregate purchase price of $15.4 million and at a price per share of $4.00 (such transaction, the "PIPE Investment").
See further discussion of the PIPE Investment in Note 11.

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 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, 2022 (the "2022 Form 10-K"). Significant accounting policies disclosed therein have not changed.
Earnings (Loss) Per Share
Basic earnings (loss) per share is computed using the weighted-average number of shares of common stock outstanding during the reporting period. Diluted earnings (loss) per share is computed in a manner consistent with that of basic earnings per share, while considering other potentially dilutive securities.
For the three months ended March 31, 2023 and 2022, potentially dilutive securities consist of unvested restricted stock awards ("RSAs") and contingent performance stock units ("PSUs"). For the three months ended March 31, 2023 potentially dilutive securities also consist of outstanding shares of Series A Preferred Stock, which contain non-forfeitable rights to earnings and dividends in the form of cash or shares of Series A Preferred Stock (the "Preferred Dividends"), determined at the option of the Company, and are deemed to be participating securities ("Participating Securities"). As permitted, the Company has elected not to separately present basic or diluted earnings (loss) per share attributable to Participating Securities in the Consolidated Statement of Operations for the three months ended March 31, 2023.
The following table sets forth the calculations of basic and diluted loss per share:
 Three Months Ended March 31,
(in thousands, except per share amounts)20232022
Net loss$(7,508)$(3,033)
Less: Dividends declared on redeemable preferred stock157 —

Diluted weighted-average shares outstanding23,770 18,344 
Loss per share - basic$(0.32)$(0.17)
Loss per share - diluted$(0.32)$(0.17)
For the three months ended March 31, 2023 and 2022, potentially dilutive securities of 4.2 million and 0.3 million shares of common stock, respectively, were outstanding but were not included in the calculation of diluted net loss per share because the effect would have been anti-dilutive.

Use of Estimates
The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. There have been no changes in the Company’s critical accounting estimates from those that were disclosed in the 2022 Form 10-K. Actual results could differ from these estimates.
Risks and Uncertainties
For 2023, the Company is principally dependent on the 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 for purposes of power generation 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 for purposes of power generation 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.
Concentration of credit risk
The Company is exposed to concentrations of credit risk primarily related to cash held at financial institutions and accounts receivable. The Company regularly monitors its credit risk to mitigate the possibility of current and future exposures resulting in a loss. Historically, the losses related to credit risk have been immaterial.
The Company evaluates the creditworthiness of its customers prior to entering into agreements to sell its products and, as necessary, throughout the life of the customer relationship.
The Company holds substantially all of its cash at one financial institution as of March 31, 2023. 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.
Reclassifications
Certain balances have been reclassified from the prior year to conform to the current year presentation. Such reclassifications had no effect on the Company’s results of operations or financial position in any of the periods presented.
New Accounting Standards
Effective January 1, 2023, the Company adopted 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. The adoption of ASU 2016-13 did not have a material impact on the Company's financial statements and disclosures.
Note 2 - Arq Acquisition
The Company accounted for the Arq Acquisition as an acquisition of a business as of the Acquisition Date. The total Purchase Consideration was $31.2 million and has been preliminarily allocated to the acquired assets and assumed liabilities of Arq based on their estimated fair values as of the Acquisition Date. The Purchase Consideration was comprised of the fair values as of the Acquisition Date of 3,814,864 shares of Common Stock, valued at $12.4 million, and 5,294,462 Preferred Shares, valued at $18.8 million. The Company also incurred $8.7 million in acquisition-related costs, which were expensed as incurred and included in the "General and administrative" line item in the Statements of Operations.

Redeemable Preferred Stock
In connection with the issuance of the Series A Preferred Stock pursuant to the Purchase Agreement, the Company filed the Certificate of Designations of Preferred Stock for the Series A Preferred Stock (the "Certificate of Designations") with the Secretary of State of the State of Delaware. Under the Certificate of Designations, 8.9 million preferred shares were designated as Series A Preferred Stock.
Each outstanding share of Series A Preferred Stock will be automatically converted into the number of shares of Common Stock described below upon approval by the stockholders of the Company. Each share of Series A Preferred Stock is deemed to have an original issue price of $4.00 per share (the "Original Issue Amount"). The number of shares of Common Stock issued upon conversion of each share of Series A Preferred Stock shall be equal to the product of (i) the sum of (A) the Original Issue Amount plus (B) an amount equal to the cumulative amount of the accrued and unpaid dividends on such share at such time divided by (ii) the Original Issue Amount, subject to adjustment.
Holders of the Series A Preferred Stock are entitled to receive cumulative dividends, which accrue quarterly on the last day of each applicable quarter (whether or not declared or funds for their payment are lawfully available) and are payable quarterly, in arrears, on the earlier to occur of (a) the date any dividend is paid to holders of Common Stock with respect to such quarter and (b) 30 days after the end of each quarter (the "Series A Quarterly Dividend") at the rate per share of Series A Preferred Stock equal to the greater of (i) if the Company declares a cash dividend on the Common Stock with respect to such quarter, the amount of the cash dividend that would be received by a holder of Common Stock in which such share of Series A Preferred Stock would be convertible on the record date for such cash dividend and (ii) an annual rate (the "Rate") of 8.0% of the Original Issue Amount compounded quarterly with respect to such quarter. The Rate will increase by 2.0% on the first day of the first quarter ending on or after the 635th day following the closing date of the first issuance of Series A Preferred Stock and on each subsequent anniversary of such date.

The Series A Quarterly Dividend is payable in cash or in additional shares of Series A Preferred Stock (the "Series A PIK Shares"), at the option of the Company. The number of Series A PIK Shares to be issued is determined by dividing (i) the Series A Quarterly Dividend payable with respect to all shares of Series A Preferred Stock held by a holder thereof by (ii) the aggregate Original Issue Amount of all shares of Series A Preferred Stock held by a holder thereof, and each fractional Series A PIK Share is rounded to the nearest whole Series A PIK Share (with 0.5 of a share being rounded down to 0.0).
On March 31, 2023, the Company declared a dividend of 68,464 Series A PIK Shares with respect to the accrued dividends on the Series A Preferred Stock for the first quarter of 2023 (the "First Quarter PIK Dividend"). The First Quarter PIK Dividend was recorded at the estimated fair value of $0.2 million as of March 31, 2023 and was paid on April 21, 2023.
In the event of the Company's liquidation, dissolution or winding up, after payment or provision for payment of its debt and other liabilities, a holder of Series A Preferred Stock will receive a liquidating distribution equal to the amount of the cumulative accrued but unpaid dividends on each share of Series A Preferred Stock held by such holder. After the payment to the holders of Series A Preferred Stock of such liquidation preference, the holders of outstanding shares of Series A Preferred Stock will participate pari passu with the holders of Common Stock on an as-converted basis in any remaining distributions out of the Company’s assets available for distribution to stockholders.
Holders of shares of Series A Preferred Stock generally have no voting rights. However, the Company is restricted from taking certain actions without the written consent or affirmative vote of the holders of at least a majority of the then outstanding shares of Series A Preferred Stock, including, but not limited to, amending the Company's Certificate of Incorporation or Bylaws in a manner that adversely affects the rights of the Series A Preferred Stock or consummating a merger of the Company with or into another party or a sale of substantially of its assets.
If the approval by the stockholders of the Company of conversion of the Series A Preferred Stock has not been obtained, each outstanding share of Series A Preferred Stock will be redeemed by the Company on February 1, 2028 for cash, at a redemption price equal to the sum of (i) the product of (x) 140% and (y) the Original Issue Amount, plus (ii) an amount equal to the cumulative amount of accrued and unpaid dividends on such share of Series A Preferred Stock.
Under the terms of the Purchase Agreement, a total of 833,914 Preferred Shares, are being held in escrow (the "Escrow Shares") based on a contingent redemption feature, (the "Contingent Redemption Feature," as defined below). The fair value of the Preferred Shares issued was determined to be $3.46 per Preferred Share on the Acquisition Date (the "Preferred Share Price") plus the value of the Contingent Redemption Feature related to the Escrow Shares.
The Escrow Shares are being withheld pending a determination by the IRS that no tax withholding is required on the Purchase Consideration issued to Arq Ltd. (the "Arq Ltd. Tax Liability"). The Company estimated the fair value of the potential Arq Ltd. Tax Liability at $3.3 million. In the event that the IRS determines that no withholding is required by Arq Ltd. in connection with the Purchase Consideration received by Arq Ltd., all of the Escrow Shares will be released and delivered to Arq Ltd. In the event that the IRS determines that any amount of withholding is required by Arq Ltd., the Company has agreed to redeem a sufficient number of Escrow Shares to fund the required payment to the IRS, and that number of Escrow Shares will be returned to the Company (the "Contingent Redemption Feature"). The number of Escrow Shares to be returned to the Company is equal to the required withholding amount divided by the Original Issue Amount, not to exceed a maximum of 833,914 Escrow Shares, and is equal to $3.3 million based on the Original Issue Amount (the "Maximum Contingent Redemption Amount"). The fair value of the Escrow Shares is the Maximum Contingent Redemption Amount and the fair value of the non-escrowed Preferred Shares ("Non Escrow Shares") is the Preferred Share Price.
The Series A Preferred Stock contains a mandatory redemption feature in the event the Preferred Shares, including future Preferred Shares issued under dividend requirements, are not converted into shares of Common Stock prior to February 1, 2028. The Company has determined that both the Escrow Shares and the Non Escrow Shares do not meet the definition of mandatorily redeemable financial instruments as there is a substantive conversion feature, and are therefore not classified as liabilities. As both the Escrow Shares and Non Escrow Shares represent financial instruments that are redeemable for cash, SEC guidance mandates that preferred securities which are redeemable upon the occurrence of an event that is not solely within the control of the issuer be classified outside of permanent equity as "temporary equity." Accordingly, the Company has classified all of the Preferred Shares as temporary equity and reported them as "Redeemable preferred stock" in the Consolidated Balance Sheet as of as of March 31, 2023.

The following represents the pro forma effects of the Arq Acquisition as if it had occurred on January 1, 2022. The pro forma net loss for each of the two years presented has been calculated after applying the Company’s accounting policies in effect for those years. In addition, pro forma net loss includes: (1) for the three months ended March 31, 2022, an increase in Payroll and benefits for compensation expense of $1.9 million payable to certain Arq employees, triggered by change in control provisions in employment agreements, as well as in employee severance agreements that has not been recognized in the historical financial statements, assuming such amounts will be paid in cash; (2) for each of the three months ended March 31, 2023 and 2022, a decrease in depreciation and amortization of $0.2 million and $0.6 million, respectively, resulting from fair value adjustments to Property, plant, equipment; (3) for each of the three months ended March 31, 2023 and 2022, an increase in amortization of $0.1 million and $0.1 million, respectively, resulting from fair value adjustments to intangible assets; (4) for each of the three months ended March 31, 2023 and 2022, increases to Interest expense of $0.2 million and $0.3 million, respectively for: (a) the issuance of the Term Loan (as defined below) including stated interest and the amortization of the Term Loan's discount and issuance costs and (b) amortization of debt discount related to a fair value adjustment to an assumed term loan of Arq; and (5) the removal of $6.6 million of transaction costs incurred for the period from April 1, 2022 to March 31, 2023 but included as additional transaction costs for the three months ended March 31, 2022, together with the income tax effects on (1) through (5). Since Arq had no revenues for the three months ended March 31, 2023 or 2022, pro forma revenues are the same as the Company's reported revenues for those periods.

Note 3 - Marshall Mine
On September 2, 2022, (the "MM Purchase Date"), a subsidiary of Advanced Emissions Solutions, Inc., ADA Carbon Solutions (Operations), LLC (the "Seller"), entered into a Membership Interest Purchase Agreement (the "MM Purchase Agreement") with Caddo Creek Resources Company, L.L.C. (the "Buyer") to sell all of its membership interests in Marshall Mine, LLC to the Buyer (the "MM Transaction") in exchange for a cash payment to be made by the Seller to the Buyer and the assumption by the Buyer of certain liabilities of Marshall Mine, LLC. The Buyer previously operated the Marshall Mine on behalf of Marshall Mine, LLC and was performing final mine reclamation under a fixed price contract.
The obligations of the Seller and the Buyer to close the Transaction were subject to certain customary closing conditions (the "Conditions") as set forth in the Purchase Agreement, including, but not limited to, (1) obtaining the approval of the Railroad Commission of Texas (the "Commission") for a change in control of Marshall Mine from Seller to Buyer or an affiliate of the Buyer; and (2) the Buyer replacing the Seller’s surety bond with a reclamation performance bond, letter of credit or other form of security to which the Buyer or an affiliate of the Buyer is the principal that is satisfactory to the Commission.
On March 27, 2023, (the "MM Closing Date") all of the Conditions for closing the MM Transaction were satisfied, and the Company made a cash payment to the Buyer in the amount of $2.2 million (the "MM Purchase Price"). As of the MM Closing Date, Marshall Mine, LLC had outstanding liabilities of approximately $4.9 million that were discharged upon payment of the MM Purchase Price by the Company, and the Company recognized a gain of approximately $2.7 million in the Statement of Operations for the three months ended March 31, 2023.

Note 4 - Revenues
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 Condensed Consolidated Balance Sheets and, if deliverable outside of one year, is included in "Other long-term liabilities" in the Condensed Consolidated Balance Sheets.

The Company may prepay the Term Loan at any time subject to the following prepayment premium: (i) prior to the twelve month anniversary of the Closing Date, the Make-Whole Amount (as defined below), (ii) thereafter but prior to the thirty-six month anniversary of the Closing Date, 2.00% of the outstanding principal amount of the Term Loan being repaid or prepaid or (iii) thereafter until the maturity date, 1.00% of the outstanding principal amount of the Term Loan being repaid or prepaid. The "Make-Whole Amount," with respect to any repayment or prepayment, is (i) an amount equal to all required interest payable (except for currently accrued and unpaid interest) on the aggregate principal amount of the Term Loan subject to such prepayment or repayment from the date of such prepayment or repayment through but excluding the date that is the first anniversary of the Closing Date calculated using an interest rate equal to (x) Adjusted Term SOFR for an interest period of one month in effect on the third U.S. Government Securities Business Day prior to such prepayment or repayment plus (y) 14.00% per annum and assuming all interest was paid in cash, plus (ii) a prepayment premium of 2.00% on the aggregate principal amount of the Term Loan subject to such prepayment or repayment.
The Term Loan is secured by substantially all of the assets of the Company and its subsidiaries (including those acquired in the Acquisition, but excluding those pledged as collateral under the Arq Loan, as defined and described below), subject to customary exceptions. The Loan Agreement includes, among others, the following covenants: (1) beginning with the first fiscal quarter after March 31, 2023 and as of the end of each fiscal quarter thereafter, the Company must maintain a minimum unrestricted cash balance of $5.0 million; (2) (x) as of December 31, 2023, for the fiscal year then ended, the Company must have a minimum annual revenue, on a consolidated basis, of $70.0 million, (y) as of December 31, 2024, for the fiscal year then ended, the Company must have a minimum annual revenue, on a consolidated basis, of $85.0 million and (z) for any fiscal year thereafter, the Company must have a minimum annual revenue, on a consolidated basis, of $100.0 million; (3) (x) as of December 31, 2024, for the fiscal year then ended, the Company must have a minimum Consolidated EBITDA of $3.0 million and (y) for any fiscal year thereafter, the Company must have a minimum Consolidated EBITDA of $16.0 million; and (4) beginning after the fiscal quarter ending September 30, 2023, during an LTV Trigger Period, ADES must not exceed a loan to value (based on the consolidated total assets of the Company and its subsidiaries) ratio of 0.40:1.00.
The Company allocated the cash proceeds of the Term Loan to both the Term Loan and the Warrant based on their relative fair values. The amount allocated to the Warrant was recorded as a debt discount and is amortized to interest expense over the term of the Term Loan. The standalone fair value of the Term Loan was based on a comparison of borrowings and associated credit ratings consistent with those of the Company. As the Warrant is exercisable for $0.01 per share, the fair value is deemed to be equal to the fair value of the underlying shares, and accordingly, the fair value of the Warrant was determined as the number of shares issuable from the exercise of the Warrant (based on 1.0% of post-transaction fully diluted share capital, as defined in the Purchase Agreement) multiplied by the closing share price of the Company's common stock on the Acquisition Date.
Arq Loan
As consideration in the Arq Acquisition, the Company assumed a term loan (the "Arq Loan") held by certain Arq subsidiaries as set out in the Arq Loan (the "Arq Borrowers") with a financial institution in the principal amount of $10.0 million. The Company recorded the Arq Loan on the Acquisition Date at its estimated fair value of $9.7 million, with the difference between the estimated fair value and the principal amount of $0.3 million recorded as a debt discount. This debt discount is recognized as interest expense over the term of the Arq Loan.
The Arq Loan was executed on January 27, 2021 and is comprised of two promissory notes (the "Notes"): (1) "Note A" in the principal amount of $8.0 million, which is guaranteed by the U.S. Department of Agriculture; and (2) "Note B" in the principal of $2.0 million. The Notes expire on January 27, 2036 and bear interest at 6.0% per annum through January 2026 and at prime plus 2.75% thereafter. Beginning January 27, 2023 and for the balance of the term of the Arq Loan, the Arq Borrowers are required to make combined interest and principal payments monthly in the fixed amount of $0.1 million. Interest is computed and payable on the outstanding principal as of the end of the prior month and the balance of the fixed monthly payment amount is applied to the outstanding principal. The Notes carry a prepayment penalty of 3.0% of the outstanding principal if paid prior to January 27, 2024, 2.0% of the outstanding principal if paid prior to January 27, 2025 and 1.0% of the outstanding principal if paid prior to January 27, 2026. Thereafter, the Arq Loan may be prepaid without penalty.
The Arq Loan is secured by substantially all assets of the Arq Borrowers and includes among others, the following covenants with respect to the Arq Borrowers, which are tested annually (Capitalized terms are defined in the Arq Loan): (a) Total Indebtedness to Net Worth greater than 4 to 1; (b) Balance Sheet Equity greater than or equal to 20% of the book value of all assets of the Arq Borrowers; (c) (i) net income plus interest, taxes, depreciation and amortization divided by (ii) interest expense plus current maturities on long-term debt greater than or equal to 1.25 to 1.

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.
Legal Proceedings

Tinuum Group, LLC
As of March 31, 2023 and December 31, 2022, the Company's ownership interest in Tinuum Group was 42.5%. For the three months ended March 31, 2023 and the three months ended March 31, 2022, the Company recognized earnings from Tinuum Group of $0.6 million and $1.0 million, respectively, which was comprised solely of cash distributions received during these periods.
In December 2022, the Company, certain of the other owners of Tinuum Group (collectively, the "Tinuum Group Owners") and Tinuum Group executed the Distribution and Repayment Agreement (the "Repayment Agreement"). Under the terms of the Repayment Agreement, the Tinuum Group Owners receive cash distributions (the "Distributions") equal to their percentage ownership and also are contractually liable for certain contingent liabilities of Tinuum Group (the "Tinuum Group Obligation") in amounts equal to their percentage ownership. In December 2022, the Company received its percentage share of the Distributions in the amount of $2.0 million and became contractually liable for $1.7 million of the Tinuum Group Obligation. As of March 31, 2023 and December 31, 2022, the Company' portion of the Tinuum Group Obligation is $1.7 million and $1.7 million, respectively and is included in the "Other current liabilities" line item in the Condensed Consolidated Balance Sheets. In the event that the Tinuum Group Obligation is discharged in its entirety or settled for an amount that is less than the total Tinuum Group Obligation, the Company will recognize future equity earnings for the difference in its portion of the Tinuum Group Obligation and its pro rata share of the actual payment made by Tinuum Group, if any, for the Tinuum Group Obligation.
In December 2022, the Company and Tinuum Group entered into an agreement (the "Tinuum Group Royalty Agreement") whereby the Company pays Tinuum Group a royalty (the "Tinuum Group Royalty") for certain of the Company's sales of its M-ProveTM products after the expiration of the Section 45 Tax Credit Program (beginning January 1, 2022) to certain of the former refined coal facilities owned by Tinuum Group and operated by Tinuum Services (the "M-45 Facilities"). The Tinuum Group Royalty is calculated based on "Net Profit" (as defined in the Tinuum Royalty Agreement) on the Company's sales of M-ProveTM product to certain of the M-45 Facilities. The Tinuum Group Royalty Agreement is for an initial term of five years with automatic renewals of five years unless the Company and Tinuum Group agree to terminate it.
For the three months ended March 31, 2023, the Company recognized $0.2 million of Tinuum Group Royalties, which are included in the "Consumables cost of revenues, excluding depreciation and amortization" line item in the Consolidated Statement of Operations.
Tinuum Services, LLC

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 tax credits if the Company experiences an "ownership change" (as defined in the Internal Revenue Code). In general, an ownership change occurs if there is a cumulative change in the ownership of the Company by "5 percent stockholders" that exceeds 50 percentage points over a rolling three-year period.
An entity that experiences an ownership change generally will be subject to an annual limitation on its pre-ownership change tax loss and credit carryforwards equal to the equity value of the entity immediately before the ownership change, multiplied by the long-term, tax-exempt rate posted monthly by the Internal Revenue Service (subject to certain adjustments). The annual limitation would be increased each year to the extent that there is an unused limitation in a prior year.

On May 5, 2017, the Board approved the declaration of a dividend of rights to purchase Series B Junior Participating Preferred Stock for each outstanding share of common stock as part of a tax asset protection plan (the "TAPP"), which is designed to protect the Company’s ability to utilize its net operating losses and tax credits. The TAPP is intended to act as a deterrent to any person acquiring beneficial ownership of 4.99% or more of the Company’s outstanding common stock.
On April 11, 2023, the Board approved the Sixth Amendment to the TAPP (the "Sixth Amendment"), which amends the TAPP, as previously amended by the First, Second, Third, Fourth and Fifth Amendments that were approved the Board on April 6, 2018, April 5, 2019, April 9, 2020, April 9, 2021 and March 15, 2022, respectively. The Sixth Amendment amends the definition of "Final Expiration Date" under the TAPP to extend the duration of the TAPP and makes associated changes in connection therewith. Pursuant to the Sixth Amendment, the Final Expiration Date shall be the close of business on the earlier of (i) December 31, 2024 or (ii) December 31, 2023 if stockholder approval of the Sixth Amendment has not been obtained prior to such date.

The Company incurred pretax loss for the three months ended March 31, 2023 and expects to incur pretax loss for the year ending December 31, 2023. As a result, the effective rate for the three months ended March 31, 2023 was zero as the resultant tax benefit was offset by a valuation allowance recorded as of March 31, 2023.
The Company assesses a valuation allowance recorded against deferred tax assets at each reporting date. The determination of whether a valuation allowance for deferred tax assets is appropriate requires the evaluation of positive and negative evidence that can be objectively verified. Consideration must be given to all sources of taxable income available to realize deferred tax assets, including, as applicable, the future reversal of existing temporary differences, future taxable income forecasts exclusive of the reversal of temporary differences and carryforwards, taxable income in carryback years and tax planning strategies. In estimating income taxes, the Company assesses the relative merits and risks of the appropriate income tax treatment of transactions taking into account statutory, judicial and regulatory guidance.

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations
The following discussion and analysis of our financial condition and results of our operations should be read together with the unaudited Condensed Consolidated Financial Statements and notes of Advanced Emissions Solutions, Inc. ("ADES" or the "Company") included elsewhere in Item 1 of Part I ("Item 1") of this Quarterly Report and with the audited consolidated financial statements and the related notes of ADES included in the 2022 Form 10-K.
The results of operations discussed in this "Management's Discussion and Analysis of Financial Condition and Results of Operations" are those of ADES and its consolidated subsidiaries, collectively, the "Company," "we," "our" or "us."
Overview
We are an environmental technology company that sells consumable products that utilize AC and chemical-based technologies to a broad range of customers, including coal-fired utilities, industrials, water treatment plants, and other diverse markets served by one of our major customers. Our primary products are comprised of AC, which is produced from a variety of carbonaceous raw materials. Our AC products include both powdered activated carbon ("PAC") and granular activated carbon ("GAC"). Our proprietary technologies and associated product offerings provide purification solutions to enable our customers to reduce certain contaminants and pollutants to meet the challenges of existing and potential future regulations. Additionally, we own an associated lignite mine which supplies the primary raw material for the manufacturing of our current products.
Acquisition
On February 1, 2023 (the "Acquisition Date"), we completed the Arq Acquisition in exchange for the Purchase Consideration of $31.2 million, which consisted of (i) 3,814,864 shares of the Company's common stock, par value $0.001 per share (the "Common Stock") and (ii) 5,294,462 shares (the "Preferred Shares") of the Company's Series A Convertible Preferred Stock, par value $0.001 per share (the "Series A Preferred Stock").
Loan Agreement
On February 1, 2023, we and CF Global ("CFG"), a related party, as administrative agent and lender (the "Lender"), entered into a term loan (the "Term Loan") in the amount of $10.0 million, less original issue discount of $0.2 million. The Term Loan has a term of 48 months and bears interest at a rate equal to either (a) Adjusted Term SOFR (subject to a 1.00% floor and a cap of 2.00%) plus a margin of 9.00% paid in cash and 5.00% paid in kind or (b) Base Rate plus a margin of 8.00% paid in cash and 5.00% paid in kind, which interest on the Term Loan in each case is payable (or capitalized, in the case of in kind interest) quarterly in arrears. The Term Loan is secured by substantially all of the assets of ADES and its subsidiaries (including those acquired in the Acquisition), subject to customary exceptions. We incurred issuance costs of $1.3 million associated with the Loan Agreement.
The Loan Agreement also provided for the issuance of the Warrant to CFG to purchase 325,457 shares of Common Stock, which represents 1% of the post-Arq Acquisition and PIPE Investment (as defined below) fully diluted share capital (as defined in the Loan Agreement), at an exercise price of $0.01 per share. The Warrant has a term of 7 years and contains a cashless exercise provision.
Equity Financing
Also on February 1, 2023, we and the Subscribers, which included existing shareholders of Arq Ltd., entered into the PIPE Investment for the purchase of 3,842,315 shares of Common Stock for an aggregate purchase price of $15.4 million and at a price per share of $4.00.
Drivers of Demand and Key Factors Affecting Profitability
Drivers of demand and key factors affecting our profitability are sales of our consumables-based solutions for coal-fired power
generation, industrials, municipal water customers and other diverse markets served by one of our major customers. Our operating results are influenced by: (1) changes in our manufacturing production and sales volumes; (2) changes in price and product mix; (3) changes in coal-fired dispatch and electricity power generation sources and (4) changes in demand for contaminant removal within water treatment facilities.
For the three months ended March 31, 2023, we experienced a decrease in demand for our product from certain coal-fired dispatch and electricity power generation customers. This was primarily due to unexpectedly low natural gas prices, resulting in certain customers opting to use natural gas versus coal for power generation, and abnormally warm temperatures during the majority of the winter season, resulting in less demand for power generation. We expect that natural gas prices will remain at current lows through 2023, and we expect this will significantly and negatively impact sales of our product. Further, lower average temperatures in the spring and summer season would also negatively impact sales of our product.

Marshall Mine
On March 27, 2023, we closed the sale of Marshall Mine, LLC and we remitted a cash payment to the Buyer in the amount of $2.2 million in connection with the sale. As of March 27, 2023, Marshall Mine, LLC had outstanding liabilities of approximately $4.9 million that were discharged upon the closing, and as a result, we recognized a gain of approximately $2.7 million for the three months ended March 31, 2023.
Results of Operations
For the three months ended March 31, 2023, we recognized net loss of $7.5 million, compared to net loss of $3.0 million for the three months ended March 31, 2022. The most significant factors impacting results period over period were increased expenses related to the Arq Acquisition as well as the decrease in demand for our AC and chemical products related to power generation as a result of prices of alternative energy sources.
The following sections provide additional information regarding these comparable periods. For comparability purposes, the following tables set forth our results of operations for the periods presented in the Condensed Consolidated Financial Statements included in Item 1 of this Quarterly Report. The current year period to prior year period comparisons of financial results may not be indicative of financial results to be achieved in future periods.
Comparison of the Three Months Ended March 31, 2023 and 2022
Total Revenue and Cost of Revenue
A summary of the components of our revenues and cost of revenue for the three months ended March 31, 2023 and 2022 is as follows:
Three Months Ended March 31,Change
(in thousands, except percentages)
20232022($)(%)
Revenues:
Consumables$20,805 $26,402 $(5,597)(21)%
Total revenues$20,805 $26,402 $(5,597)(21)%
Operating expenses:
Consumables cost of revenue, exclusive of depreciation and amortization$17,175 $21,507 $(4,332)(20)%
Consumables and consumables cost of revenue
For the three months ended March 31, 2023, consumables revenues decreased from the comparable quarter in 2022 primarily driven by a decrease in volumes sold, which comprised $5.9 million of the total change. Product volumes were lower among power generation customers primarily due to low natural gas prices compared to the same quarter in 2022, which contributed to decreased utilization of coal-fired generation and decreased demand for our products. The average natural gas spot prices ($MMBtu) for the three months ended March 31, 2023 and 2022 were $2.65 and $4.66, respectively. Total consumables revenues also decreased for the three months ended March 31, 2023 by approximately $1.0 million from the comparable quarter due to unfavorable product mix. Offsetting these decreases to Consumables revenues were overall higher pricing of our products by approximately $1.6 million from the comparable quarter in 2022.
Consumables gross margin, exclusive of depreciation and amortization, decreased for the three months ended March 31, 2023, compared to the comparable quarter in 2022. Driving the decrease in gross margin quarter over quarter were sales volume changes as discussed above, higher prices for key raw materials, transportation, including fuel, and other operational costs to produce and deliver our products and a negative impact from net electricity generated. Offsetting these negative impacts was an increase in the prices of our products, most of which were in place as of the beginning of April 2022.
For 2023, and based on current market estimates, we believe there will be a slight increase in Consumables revenue in the second half of 2023 compared to the first half of 2023, driven by changes to customer and product mix, and overall improvements in pricing. However, we expect to see slight decreases in volumes compared to 2022 due to prices of alternative energy sources impacting the demand for our AC and chemical products related to power generation. There is risk to our volumes outlook driven by inflationary pressures that may increase our overall operating costs for our manufacturing operations as well as the impact of the 2023 Red River Plant turnaround.
Consumables revenues continues to be affected by electricity demand driven by seasonal weather and related power generation needs, as well as competitor prices related to alternative power generation sources such as natural gas and renewables.

Payroll and benefits
Payroll and benefits expenses, which represent costs related to selling, general and administrative personnel, increased for the three months ended March 31, 2023 compared to the corresponding quarter in 2022 primarily due to the addition of Arq employees, which increased expenses by $2.2 million, of which $1.3 million related to severance expense of former executives of Arq. These increases were offset by a decrease in expense relate to retention agreements with our executive officers and certain other key employees of $0.3 million, as these bonuses were paid in January 2023.
Legal and professional fees
Legal and professional fees increased for the three months ended March 31, 2023 compared to the corresponding quarter in 2022 as a result of an increase in costs incurred related to the Arq Acquisition, and was comprised mostly of legal and consulting fees. For the three months ended March 31, 2023, $2.4 million of legal and professional fees related to non-recurring transactions costs incurred as a result of the Arq Acquisition.
General and administrative
General and administrative expenses increased for the three months ended March 31, 2023 compared to the corresponding quarter in 2022 as a result of $0.6 million expenses incurred by Arq for quarter, which includes $0.3 million related to rent and occupancy expense from additional leased space. Additional increases of approximately $0.3 million quarter over quarter related to increases in travel, recruiting and Board compensation, as three new board members were added to our Board in connection with the Arq Acquisition.
Depreciation, amortization, depletion and accretion
Depreciation and amortization expense increased for the three months ended March 31, 2023 compared to the corresponding quarter in 2022 primarily due to depreciation and amortization of approximately $0.6 million from the addition of long-lived assets and intangible assets acquired as part of the Arq Acquisition.
Gain on sale of Marshall Mine, LLC
As discussed above, for the three months ended March 31, 2023, we recognized a gain of $2.7 million on the sale of Marshall Mine, LLC.

Additional information related to equity method investments is included in Note 10 to the Condensed Consolidated Financial Statements included in Item 1 of this Report.
Interest expense
Interest expense increased for the three months ended March 31, 2023 compared to the corresponding quarter in 2022 due to interest expense of $0.3 million related to the Term Loan, which was entered into on February 1, 2023 in connection with the Arq Acquisition. Additional interest expense of $0.1 million related to the Arq Loan, which we assumed as result of the Arq Acquisitions.
Income tax expense
For three months ended March 31, 2023, we had pretax loss of $7.5 million and recorded income tax benefit related to out-of-period state income tax refunds received during the quarter. We recorded no additional income tax benefit for this quarter due to the recording of a full valuation allowance based on our forecast of pretax loss for the year ending December 31, 2023. For the three months ended March 31, 2022, we had pretax loss of $3.0 million and recorded no income tax benefit due to the recording of a full valuation allowance based on our forecast of pretax loss for the year ended December 31, 2022.

Non-GAAP Financial Measures
To supplement our financial information presented in accordance with U.S. GAAP (or "GAAP"), we provide non-GAAP measures of certain financial performance. These non-GAAP measures include EBITDA (EBITDA Loss) and Adjusted EBITDA (Adjusted EBITDA Loss). We have included these non-GAAP measures because management believes that they help to facilitate period to period comparisons of our operating results and provide useful information to both management and users of the financial statements by excluding certain expenses, gains and losses which may not be indicative of core operating results and business outlook. Management uses these non-GAAP measures in evaluating the performance of our business.
These non-GAAP measures are not in accordance with, or an alternative to, measures prepared in accordance with GAAP and may be different from non-GAAP measures used by other companies. In addition, these non-GAAP measures are not based on any comprehensive set of accounting rules or principles. These measures should only be used to evaluate our results of operations in conjunction with the corresponding GAAP measures.
We define EBITDA (EBITDA Loss) as net income (loss) adjusted for the impact of the following items that are either non-cash or that we do not consider representative of our ongoing operating performance: depreciation, amortization, depletion, accretion, amortization of upfront customer consideration ("Upfront Customer Consideration"), interest expense, net and income taxes. We define Adjusted EBITDA (Adjusted EBITDA Loss) as EBITDA (EBITDA Loss), reduced by the non-cash impact of equity earnings from equity method investments and gain on sale of Marshall Mine, LLC, increased by cash distributions from equity method investments and loss on early settlement of a long-term receivable. Because Consolidated Adjusted EBITDA omits certain non-cash items, we believe that the measure is less susceptible to variances that affect our operating performance.
When used in conjunction with GAAP financial measures, we believe these non-GAAP measures are supplemental measures of operating performance which explain our operating performance for our period-to-period comparisons and against our competitors' performance. Generally, we believe these non-GAAP measures are less susceptible to variances that affect our operating performance results.
We expect the adjustments to Consolidated EBITDA and Consolidated Adjusted EBITDA in future periods will be generally similar. These non-GAAP measures have limitations as analytical tools and should not be considered in isolation or as a substitute for analyzing our results as reported under GAAP.

Cash flows used in operating activities for the three months ended March 31, 2023 decreased by $19.8 million compared to the three months ended March 31, 2022. The net decrease was primarily attributable to net loss of $7.5 million recognized for the three months ended March 31, 2023 compared to net loss of $3.0 million recognized for the three months ended March 31, 2022; the add-back of a non-cash gain of $2.7 million recognized from the sale of Marshall Mine, LLC for the three months ended March 31, 2023; a decrease in accounts payable and accrued expenses of $10.8 million, primarily from payments of Arq assumed liabilities comprised of accrued employee-related compensation and accrued transaction costs associated with the Arq Acquisition; payment of the balance of the Retention Bonuses; and a decrease in Distributions from equity method investees, return on investment of $1.5 million. Offsetting the net decrease in cash flows provided by operating activities for the three months ended March 31, 2023 compared to the three months ended March 31, 2022 were an increase in net working capital, excluding accounts payable and accrued expenses, of $3.5 million, a decrease in Earnings from equity method investments of $0.2 million, and a decrease in Other long-term assets, net of $3.6 million, primarily from the payment received from settlement on a long-term receivable in the prior period.
Cash flow from investing activities
Cash flows used in investing activities increased for the three months ended March 31, 2023 compared to the three months ended March 31, 2022 by $2.5 million primarily as a result of an increase in property, plant and equipment additions of $2.2 million and the sale of Marshall Mine, LLC, which required a cash payment of $2.2 million. Additionally, distributions from equity earnings in excess of cumulative earnings decreased $0.4 million quarter over quarter. Offsetting the net increase in cash flows used in investing activities was $2.2 million of cash acquired in the Arq Acquisition.
Cash flow from financing activities
Cash flows provided by financing activities for the three months ended March 31, 2023 compared to the three months ended March 31, 2022 increased by $23.9 million primarily due to the net borrowings, net of debt issuance costs paid, of $8.5 million on the Term Loan and net proceeds from the PIPE Investment of $15.2 million.

Material Cash Requirements
With the Arq Acquisition, we have assumed liabilities, including the Arq Loan, that will increase our cash requirements for the next 12 months and beyond. In addition, our success with the Arq acquisition will require significant capital expenditures as quantified below. With the execution of the Term Loan in February 2023, we are required to make quarterly interest payments beginning in March 2023 through February 2027, and a balloon payment of principal and PIK interest totaling approximately $12.4 million on the expiration date of the Term Loan. We expect that our cash on hand as of March 31, 2023 will provide sufficient liquidity to fund our required contractual obligations due and operating loss incurred for the next 12 months.
Capital Expenditures
For 2023, we expect to incur between $40.0 million and $45.0 million in capital expenditures, including:
•Between $13.0 million and $15.0 million is forecast for capital improvements at the Red River Plant related to scheduled maintenance improvements and to complete current capital projects; and
•Between $27.0 million and $30.0 million is forecast for growth capital for the modification of the both the Red River Plant and Corbin Plant in order to incorporate Arq Powder as feedstock.
We expect to fund all capital expenditures for 2023 from cash on hand.
Surety Bonds and Mine Obligations
As of March 31, 2023, we had outstanding surety bonds with regulatory commissions totaling $7.5 million related to reclamation of the Five Forks Mine. As of March 31, 2023, and as required by our surety bond provider, we also held restricted cash of $10.0 million pledged as collateral for such surety bonds related to the Five Forks Mine and other surety obligations. Prior to March 31, 2023, and as a result of the sale of Marshall Mine, LLC, we reduced our surety bonds by $16.6 million in discharge of all future obligations for reclamation of the Marshall Mine. Subsequent to March 31, 2023, we reduced our required restricted cash to $7.7 million.
As March 31, 2023, we had outstanding surety bonds with a regulatory commission totaling $3.0 million for reclamation obligations of the land adjacent to the Corbin Facility.
We expect that the obligations secured by these surety bonds associated with Five Forks will be performed in the ordinary course of business and in accordance with the applicable contractual terms. To the extent that the obligations are performed, the related surety bonds should be released and collateral requirements reduced. However, in the event any surety bond is called, our indemnity obligations could require us to reimburse the surety bond provider. We intend to fund our mine reclamation costs associated with the Five Forks Mine from cash on hand.

Our disclosure controls and procedures are designed to ensure that information required to be disclosed in the reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms. Based upon this evaluation, our principal executive officer and principal financial officer concluded that our disclosure controls and procedures were effective as of March 31, 2023.

PART II. OTHER INFORMATION
Item 1. Legal Proceedings
From time to time, we are involved in litigation, claims and other proceedings related to the conduct of our business. Information with respect to this item may be found in Note 8 "Commitments and Contingencies" to the consolidated financial statements included in Item 1 of Part I of this Quarterly Report.
Item 1A. Risk Factors
There are no material updates to our risk factors as disclosed in the 2022 Form 10-K except as described below.
Bank failures or other events affecting financial institutions could have a material adverse effect on our business, results of operations or financial condition, or have other adverse consequences.
We primarily use one U.S. bank for our operations. The majority of our cash deposits are held by this bank and exceed the Federal Deposit Insurance Corporation ("FDIC") insurance limits. The failure of this bank or events involving limited liquidity, non-performance or other adverse conditions in the financial or credit markets impacting this bank, or concerns or rumors about such events, may lead to disruptions in access to our cash balances, adversely impact our liquidity or limit our ability to process transactions related to our customers. In the event of a failure of this bank, there can be no assurance that our deposits in excess of the FDIC or other comparable insurance limits will be recoverable or, even if ultimately recoverable, there may be significant delays in our ability to access those funds. Furthermore, bank failures, non-performance, or other adverse developments that affect other financial institutions could impair the ability of this bank to honor its commitments. Such events could have a material adverse effect on our financial condition or results of operations.
Similarly, our customers may be adversely affected by any bank failure or other event affecting financial institutions. If our customers are unable, or if our customers in the future are unable, to meet their obligations to us as a result of a bank failure or other event affecting financial institutions, we may be exposed to potential risks that could impact our financial condition or results of operations. Furthermore, a significant change in the liquidity or financial position of our customers could cause unfavorable trends in cash collections, which could have a material adverse effect on our financial condition or results of operations.
Item 2. Unregistered Sales of Equity Securities and Use of Proceeds
On February 1, 2023, we entered into Subscription Agreements (the "Subscription Agreements") with certain persons (the "Subscribers"), which included existing shareholders of Arq Ltd., three of which were appointed to our Board of Directors, pursuant to which the Subscribers subscribed for and purchased shares of our common stock for an aggregate purchase price of $15.4 million and at a price per share of $4.00 (such transaction, the "PIPE Investment").
The securities issued to the Subscribers under the Subscription Agreements were issued pursuant to an exemption from registration under Section 4(a)(2) of the Securities Act, Rule 506 of Regulation D, which is promulgated thereunder, and Regulations S of the Securities Act. We are relying on this exemption from registration based in part on representations made by each of the Subscribers under the Subscription Agreements. The sale of the securities pursuant to the Subscription Agreements has not been registered under the Securities Act or any state securities laws. The securities may not be offered or sold in the United States absent registration or an applicable exemption from registration requirements.
Item 3. Defaults Upon Senior Securities
None.
Item 4. Mine Safety Disclosures
The statement concerning mine safety violations or other regulatory matters required by Section 1503(a) of the Dodd-Frank Wall Street Reform and Consumer Protection Act and Item 104 of Regulation S-K is included in Exhibit 95.1 to this Quarterly Report.
