Notes to Condensed Consolidated Financial Statements

(unaudited)

1. Basis of Presentation

The accompanying unaudited condensed consolidated financial statements include the accounts of Arch Resources, Inc. (“Arch Resources”) and its subsidiaries (“Arch” or the “Company”). Unless the context indicates otherwise, the terms “Arch” and the “Company” are used interchangeably in this Quarterly Report on Form 10-Q. The Company’s primary business is the production of metallurgical and thermal coal from surface and underground mines located throughout the United States, for sale to steel producers, utility companies, industrial accounts both in the United States and around the world. The Company currently operates mining complexes in West Virginia, Illinois, Wyoming and Colorado. All subsidiaries are wholly-owned. Intercompany transactions and accounts have been eliminated in consolidation.

The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States for interim financial reporting and U.S. Securities and Exchange Commission regulations. In the opinion of management, all adjustments, consisting of normal, recurring accruals considered necessary for a fair presentation, have been included. Results of operations for the three and nine months ended September 30, 2020 are not necessarily indicative of results to be expected for the year ending December 31, 2020. These financial statements should be read in conjunction with the audited financial statements and related notes as of and for the year ended December 31, 2019 included in the Company’s Annual Report on Form 10-K filed with the U.S. Securities and Exchange Commission.

Effective May 15, 2020, Arch Coal, Inc. announced that its name changed to Arch Resources, Inc.

2. Accounting Policies

Recently Adopted Accounting Guidance

In June 2016, the FASB issued ASU 2016-13, “Financial Instruments-Credit Losses (Topic 326), Measurement of Credit Losses on Financial Instruments,” and also issued subsequent amendments to the initial guidance under ASU 2018-19, ASU 2019-04 and ASU 2019-05. The standard modifies the measurement approach for credit losses on financial instruments, including trade receivables, from an incurred loss method to a current expected credit loss method, otherwise known as “CECL.” The standard requires the measurement of expected credit losses to be based on relevant information, including historical experience, current conditions and a forecast that is supportable. The Company adopted the standard in the first quarter of 2020, with minimal impact to the Company’s financial results.

As part of the adoption, the Company reviewed its portfolio of available-for-sale debt securities in an unrealized loss position, and assessed whether it intends to sell, or it is more likely than not that it will be required to sell before recovery of its amortized cost basis. The Company determined that it currently does not intend to sell these securities before recovery of their amortized cost basis. Additionally, the Company evaluated whether the decline in fair value has resulted from credit losses or other factors by considering the extent to which the fair value is less than amortized cost, any changes to the rating of the security by a rating agency, and adverse conditions specifically related to the security, among other factors. If this assessment indicates that a credit loss exists, the Company compares the present value of the cash flows expected to be collected against the amortized cost basis. A credit loss is recorded if the present value of the cash flows is less than the amortized cost basis, limited by the amount that the fair value is less than the amortized cost basis. Upon adoption, the Company did not record an allowance for credit losses on its available-for-sale debt securities.

Additionally, the Company reviewed its open trade receivables arising from contractual coal sales. As part of its analysis, the Company performs periodic credit reviews of all active customers, reviews all trade receivables greater than 90 days past due, calculates historical loss rates and reviews current payment trends of all customers.

Recent Accounting Guidance Issued Not Yet Effective

In December 2019, the FASB issued ASU 2019-12, “Income Taxes (Topic 740) Simplifying the Accounting for Income Taxes.” ASU 2019-12 eliminates certain exceptions related to the approach for intraperiod tax allocation, the methodology for calculating income taxes in an interim period and the recognition of deferred tax liabilities for outside basis differences. The ASU is effective for public companies for fiscal years beginning after December 15, 2020, and interim periods therein with early adoption permitted. The Company is reviewing the provisions of the standard but does not expect a significant impact to the Company's financial statements.

In March 2020, the FASB issued ASU 2020-04, "Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting." The amendments provide optional guidance for a limited time to ease the potential burden in accounting for reference rate reform. The new guidance provides optional expedients and exceptions for applying U.S. GAAP to contracts, hedging relationships and other transactions affected by reference rate reform if certain criteria are met. The amendments apply only to contracts and hedging relationships that reference LIBOR or another reference rate expected to be discontinued due to reference rate reform. These amendments are effective immediately and may be applied prospectively to contract modifications made and hedging relationships entered into or evaluated on or before December 31, 2022. We are currently evaluating our contracts and the optional expedients provided by the new standard.

3. Joint Venture with Peabody Energy

On June 18, 2019, Arch Coal, Inc. (now Arch Resources) entered into a definitive implementation agreement (the “Implementation Agreement”) with Peabody Energy Corporation (“Peabody”), to establish a joint venture that would have combined the respective Powder River Basin and Colorado mining operations of Arch Resources and Peabody. Pursuant to the terms of the Implementation Agreement, Arch Resources would have held a 33.5% economic interest, and Peabody would have held a 66.5% economic interest in the joint venture.

On February 26, 2020, the Federal Trade Commission (“FTC”) filed an administrative complaint challenging the proposed joint venture alleging the transaction will eliminate competition between Arch Resources and Peabody, the two major competitors in the market for thermal coal in the Southern Powder River Basin and the two largest coal-mining companies in the United States. The FTC filed a temporary restraining order and preliminary injunction in the U.S. District Court for the Eastern District of Missouri, to maintain the status quo pending an administrative trial on the merits.

Between July 14 and July 23, 2020, the U.S. District Court conducted an evidentiary hearing, during which both sides further presented their evidence and arguments. On September 29, 2020, the U.S. District Court upheld the FTC’s decision to block the joint venture. Subsequently, the Company and Peabody jointly terminated the joint venture.

The Company has incurred expenses of $4.4 million and $15.9 million for the three and nine months ended September 30, 2020, respectively, associated with the regulatory approval process related to the joint venture. Costs of $3.8 million and $6.8 million were incurred for the three and nine months ended September 30, 2019, respectively.

4. Gain on Property Insurance Recovery Related to Mountain Laurel Longwall

The Company recorded a $23.5 million gain related to a property insurance recovery on the longwall shields at its Mountain Laurel operation during the nine months ended September 30, 2020. As a result of geologic conditions in the final longwall panel, Mountain Laurel was unable to recover 123 of the longwall system’s 176 hydraulic shields. All of the cash associated with the insurance recovery was received by the end of the second quarter of 2020.

5. Severance Costs Related To Voluntary Separation Plan

The Company recorded $13.3 million of employee severance expense related to a voluntary separation plan during the nine months ended September 30, 2020. During the first and second quarters of 2020, 53 members of the corporate staff and 201 employees from the Company’s thermal operations accepted the voluntary separation package.

6. Divestitures

During the second quarter of 2020, various Dal-Tex and Briar Branch properties in West Virginia were sold to Condor Holdings, LLC. No consideration was received for the sale and a gain of $1.4 million was recorded representing the net liabilities sold.

On September 14, 2017, the Company sold Lone Mountain Processing, LLC and two idled mining companies, Cumberland River Coal LLC and Powell Mountain Energy LLC to Revelation Energy LLC, and recorded a gain on the transaction in that year of $21.3 million. Under the terms of the purchase agreement, Revelation assumed certain traumatic workers compensation claims and pneumoconiosis (occupational disease) benefits. On July 1, 2019, Blackjewel LLC and four affiliates, including Revelation Energy LLC filed for Chapter 11 bankruptcy. As a result of the bankruptcy, the Company recorded a $4.3 million charge for these claims as of September 30, 2019.

7. Preference Rights Lease Application Settlement Income

The Company recorded a $39 million gain during the third quarter of 2019 related to a settlement with the United States Department of Interior over a long-standing dispute, dating back to the 1970’s, on the valuation and disposition of Preference Rights Lease Applications that Arch controlled in northwestern New Mexico with a joint venture partner. As part of the settlement, Arch received $67.0 million in the form of royalty credits on its federal coal leases which will be used to settle 50% of the Company’s monthly royalty obligations. The Company expects to realize the royalty credits beginning in September 2019 through the next 18-24 months depending on market conditions. Additionally, as part of the settlement, the Company made a one-time payment of $27.0 million during October 2019 to its’ partner in the venture for its ownership interest in the underlying mineral reserves, as well as paid $1.0 million in closing fees.

As of September 30, 2020, the Company realized $8.7 million and $25.8 million towards its royalty obligations for the three months and nine months ended September 30, 2020. The Company realized a credit of $5 million towards its royalty obligations during the quarter ended September 30, 2019. The remaining receivable balance outstanding at September 30, 2020 is $27.8 million which is expected to be received over the next three quarters.

8. Asset Impairment

The following table summarizes the amounts reflected on the line “Asset impairment” in the Condensed Consolidated Statements of Operations:

	September 30,
Description	2020
	(In thousands)
Coal lands and mineral rights	$	33,197
Plant and equipment		43,197
Deferred development		50,527
Equity Investment		36,167
	$	163,088

The Company’s thermal coal segments have experienced reduced demand as a result of sustained low natural gas pricing, reduced utilization and retirement of coal-fired power plants, the increased use of renewable energy sources, and the impact of COVID-19. The reduced demand has led to lower production levels, higher unit costs, and lower realized prices, which have contributed to operating losses at certain of the mine complexes. Further, on September 29, 2020 the U.S. District Court upheld the FTC’s decision to block the Company’s proposed joint venture. These conditions have resulted in changes to the Company’s expectations for projected future volume levels and the overall longevity of the mines. During the third quarter of 2020, the Company determined that these conditions represented indicators of impairment with respect to certain of its long-lived assets or asset groups. As a result, the Company recorded impairment charges during the three and nine months ended September 30, 2020 of $51.8 million related to the Coal Creek Mine within the Powder River Basin Mining segment, $33.5 million related to the Viper Mine within the Other Thermal Segment, $41.6 million related to the West Elk Mine within the Other Thermal segment and $36.2 million related to the Company’s equity method investment in Knight Hawk Holdings, LLC. The impairment charges were based upon

11

estimated discounted cash flows that were based on estimates of future sales volumes, coal prices for unpriced volumes, production costs and a risk-adjusted cost of capital. These estimates generally constitute unobservable Level 3 inputs under the fair value hierarchy.

11. Investments in Available-for-Sale Securities

The Company has invested in marketable debt securities, primarily highly liquid U.S. Treasury securities and investment grade corporate bonds. These investments are held in the custody of a major financial institution. These securities are classified as available-for-sale securities and, accordingly, the unrealized gains and losses are recorded through other comprehensive income.

The Company’s investments in available-for-sale marketable securities are as follows:

	September 30, 2020
			Gross					Allowance
			Unrealized					for Credit	Fair
	Cost Basis		Gains		Losses			Losses	Value

Total Investments	$	135,687	$	201	$	(221)	$	—	$	135,667

The aggregate fair value of investments with unrealized losses that were owned for less than a year was $48.5 million and $72.3 million at September 30, 2020 and December 31, 2019, respectively. The aggregate fair value of investments with unrealized losses that were owned for over a year was $9.6 million and $0.0 million at September 30, 2020 and December 31, 2019, respectively. The unrealized losses in the Company’s portfolio at September 30, 2020 are the result of normal market fluctuations. The Company does not currently intend to sell these investments before recovery of their amortized cost base.

The debt securities outstanding at September 30, 2020 have maturity dates ranging from the fourth quarter of 2020 through the first quarter of 2022. The Company classifies its investments as current based on the nature of the investments and their availability to provide cash for use in current operations.

12. Derivatives

Interest rate risk management

The Company has entered into interest rate swaps to reduce the variability of cash outflows associated with interest payments on its variable rate term loan. These swaps have been designated as cash flow hedges. For additional information on these arrangements, see Note 14, “Debt and Financing Arrangements,” in the Condensed Consolidated Financial Statements.

Diesel fuel price risk management

The Company is exposed to price risk with respect to diesel fuel purchased for use in its operations. The Company anticipates purchasing approximately 30 to 35 million gallons of diesel fuel for use in its operations annually. To protect the Company’s cash flows from increases in the price of diesel fuel for its operations, the Company uses forward physical diesel purchase contracts, purchased heating oil call options and New York Mercantile Exchange (“NYMEX”) gulf coast diesel swaps and options. At September 30, 2020, the Company had protected the price on the majority of its expected diesel fuel purchases for the remainder of 2020 with approximately 2 million gallons of heating oil call options with an average strike price of $1.76 per gallon and 2.0 million gallons of NYMEX gulf coast diesel swaps at an average price of approximately $1.05 per gallon. These positions are not designated as hedges for accounting purposes, and therefore, changes in the fair value are recorded immediately to earnings.

Coal price risk management positions

The Company may sell or purchase forward contracts, swaps and options in the over-the-counter coal market in order to manage its exposure to coal prices. The Company has exposure to the risk of fluctuating coal prices related to forecasted, index-priced sales or purchases of coal or to the risk of changes in the fair value of a fixed price physical sales contract. Certain derivative contracts may be designated as hedges of these risks.

At September 30, 2020, the Company held derivatives for risk management purposes that are expected to settle in the following years:

(Tons in thousands)	2020	2021	Total
Coal sales	255	33	288
Coal purchases	238	—	238

The Company has also entered into a minimal quantity of natural gas put options to protect the Company from decreases in natural gas prices, which could impact thermal coal demand. These options are not designated as hedges.

Coal trading positions

The Company may sell or purchase forward contracts, swaps and options in the over-the-counter coal market for trading purposes. The Company is exposed to the risk of changes in coal prices on the value of its coal trading portfolio. The estimated future realization of the value of the trading portfolio is $0.2 million of losses during the remainder of 2020 and $0.3 million of gains during 2021.

Tabular derivatives disclosures

The Company has master netting agreements with all of its counterparties which allow for the settlement of contracts in an asset position with contracts in a liability position in the event of default or termination. Such netting arrangements reduce the Company’s credit exposure related to these counterparties. For classification purposes, the Company records the net fair value of all the positions with a given counterparty as a net asset or liability in the Condensed Consolidated Balance Sheets. The amounts shown in the table below represent the fair value position of individual contracts, and not the net position presented in the accompanying Condensed Consolidated Balance Sheets.

Term Loan Facility

In 2017, the Company entered into a senior secured term loan credit agreement (the “Credit Agreement”) in an aggregate principal amount of $300 million (the “Term Loan Debt Facility”) with Credit Suisse AG, Cayman Islands Branch, as administrative agent and collateral agent, and the other financial institutions from time to time party thereto (collectively, the “Lenders”). The Term Loan Debt Facility was issued at 99.50% of the face amount and will mature on March 7, 2024. The term loans provided under the Term Loan Debt Facility (the “Term Loans”) are subject to quarterly principal amortization payments in an amount equal to $750,000.

During 2018, the Company entered into the Second Amendment (the “Second Amendment”) to its Credit Agreement. The Second Amendment reduced the interest rate on its Term Loan Debt Facility to, at the option of Arch Resources, either (i) the London interbank offered rate (“LIBOR”) plus an applicable margin of 2.75%, subject to a 1.00% LIBOR floor, or (ii) a base rate plus an applicable margin of 1.75%. The LIBOR floor remains at 1.00%. There is no change to the maturities as a result of the Second Amendment.

The Term Loan Debt Facility is guaranteed by all existing and future wholly owned domestic subsidiaries of the Company (collectively, the “Subsidiary Guarantors” and, together with Arch Resources, the “Loan Parties”), subject to customary exceptions, and is secured by first priority security interests on substantially all assets of the Loan Parties, including 100% of the voting equity interests of directly owned domestic subsidiaries and 65% of the voting equity interests of directly owned foreign subsidiaries, subject to customary exceptions.

18

The Company has the right to prepay the Term Loan at any time, and from time to time, in whole or in part without premium or penalty, upon written notice, except that any prepayment of the Term Loan that bear interest at the LIBOR Rate other than at the end of the applicable interest periods therefore shall be made with reimbursement for any funding losses and redeployment costs of the Lenders resulting therefrom.

The Term Loan Debt Facility is subject to certain usual and customary mandatory prepayment events, including 100% of net cash proceeds of (i) debt issuances (other than debt permitted to be incurred under the terms of the Term Loan Debt Facility) and (ii) non-ordinary course asset sales or dispositions, subject to customary thresholds, exceptions and reinvestment rights.

The Term Loan Debt Facility contains customary affirmative covenants and representations.

The Term Loan Debt Facility also contains customary negative covenants, which, among other things, and subject to certain exceptions, include restrictions on (i) indebtedness, (ii) liens, (iii) liquidations, mergers, consolidations and acquisitions, (iv) disposition of assets or subsidiaries, (v) affiliate transactions, (vi) creation or ownership of certain subsidiaries, partnerships and joint ventures, (vii) continuation of or change in business, (viii) restricted payments, (ix) prepayment of subordinated and junior lien indebtedness, (x) restrictions in agreements on dividends, intercompany loans and granting liens on the collateral, (xi) loans and investments, (xii) sale and leaseback transactions, (xiii) changes in organizational documents and fiscal year and (xiv) transactions with respect to bonding subsidiaries. The Term Loan Debt Facility does not contain any financial maintenance covenants.

The Term Loan Debt Facility contains customary events of default, subject to customary thresholds and exceptions, including, among other things, (i) nonpayment of principal and nonpayment of interest and fees, (ii) a material inaccuracy of a representation or warranty at the time made, (iii) a failure to comply with any covenant, subject to customary grace periods in the case of certain affirmative covenants, (iv) cross-events of default to indebtedness of at least $50 million, (v) cross-events of default to surety, reclamation or similar bonds securing obligations with an aggregate face amount of at least $50 million, (vi) uninsured judgments in excess of $50 million, (vii) any loan document shall cease to be a legal, valid and binding agreement, (viii) uninsured losses or proceedings against assets with a value in excess of $50 million, (ix) certain ERISA events, (x) a change of control or (xi) bankruptcy or insolvency proceedings relating to the Company or any material subsidiary of the Company.

Accounts Receivable Securitization Facility

On September 30, 2020, the Company amended and extended its existing trade accounts receivable securitization facility provided to Arch Receivable Company, LLC, a special-purpose entity that is a wholly owned subsidiary of Arch Resources (“Arch Receivable”) (the “Extended Securitization Facility”), which supports the issuance of letters of credit and requests for cash advances. The amendment to the Extended Securitization Facility reduces the size of the facility from $160 million to $110 million of borrowing capacity and extended the maturity date to September 29, 2023. Additionally, the amendment eliminated the provision that accelerated maturity upon liquidity falling below a specified level. Pursuant to the Extended Securitization Facility, Arch Receivable also agreed to a revised schedule of fees payable to the administrator and the providers of the Extended Securitization Facility.

Under the Extended Securitization Facility, Arch Receivable, Arch Resources and certain of Arch Resources’s subsidiaries party to the Extended Securitization Facility have granted to the administrator of the Extended Securitization Facility a first priority security interest in eligible trade accounts receivable generated by such parties from the sale of coal and all proceeds thereof. As of September 30, 2020, letters of credit totaling $50.0 million were outstanding under the facility with $34.5 million available for borrowings.

Inventory-Based Revolving Credit Facility

On September 30, 2020, the Company and certain of its subsidiaries amended the senior secured inventory-based revolving credit facility in an aggregate principal amount of $50 million (the “Inventory Facility”) with Regions Bank (“Regions”) as administrative agent and collateral agent, as lender and swingline lender (in such capacities, the “Lender”) and as letter of credit issuer. Availability under the Inventory Facility is subject to a borrowing base consisting of (i) 85% of the net orderly liquidation value of eligible coal inventory, (ii) the lesser of (x) 85% of the net orderly

19

liquidation value of eligible parts and supplies inventory and (y) 35% of the amount determined pursuant to clause (i), and (iii) 100% of Arch Resources’s Eligible Cash (defined in the Inventory Facility), subject to reduction for reserves imposed by Regions.

The amendment of the Inventory Facility extended the maturity of the facility to September 29, 2023; eliminated the provision that accelerated maturity upon liquidity falling below a specified level; and reduced the minimum liquidity requirement from $175 million to $100 million. Additionally, the amendment includes provisions that reduce the advance rates for coal inventory and parts and supplies, depending on Liquidity.

Revolving loan borrowings under the Inventory Facility bear interest at a per annum rate equal to, at the option of Arch Resources, either the base rate or the London interbank offered rate plus, in each case, a margin ranging from 2.50% to 3.50% (in the case of LIBOR loans) and 1.00% to 1.50% (in the case of base rate loans) determined using a Liquidity-based grid. Letters of credit under the Inventory Facility are subject to a fee in an amount equal to the applicable margin for LIBOR loans, plus customary fronting and issuance fees.

All existing and future direct and indirect domestic subsidiaries of Arch Resources, subject to customary exceptions, will either constitute co-borrowers under or guarantors of the Inventory Facility (collectively with Arch Resources, the “Loan Parties”). The Inventory Facility is secured by first priority security interests in the ABL Priority Collateral (defined in the Inventory Facility) of the Loan Parties and second priority security interests in substantially all other assets of the Loan Parties, subject to customary exceptions (including an exception for the collateral that secures the Extended Securitization Facility).

Arch Resources has the right to prepay borrowings under the Inventory Facility at any time and from time to time in whole or in part without premium or penalty, upon written notice, except that any prepayment of such borrowings that bear interest at the LIBOR rate other than at the end of the applicable interest periods therefore shall be made with reimbursement for any funding losses and redeployment costs of the Lender resulting therefrom.

The Inventory Facility is subject to certain usual and customary mandatory prepayment events, including non-ordinary course asset sales or dispositions, subject to customary thresholds, exceptions (including exceptions for required prepayments under Arch Resources’s term loan facility) and reinvestment rights.

The Inventory Facility contains certain customary affirmative and negative covenants; events of default, subject to customary thresholds and exceptions; and representations, including certain cash management and reporting requirements that are customary for asset-based credit facilities. The Inventory Facility also includes a requirement to maintain Liquidity equal to or exceeding $100 million at all times. As of September 30, 2020, letters of credit totaling $29.2 million were outstanding under the facility with $14.8 million available for borrowings.

Equipment Financing

On March 4, 2020, the Company entered into an equipment financing arrangement accounted for as debt. The Company received $53.6 million in exchange for conveying an interest in certain equipment in operation at its Leer Mine and entered into a master lease arrangement for that equipment. The financing arrangement contains customary terms and events of default and provides for 48 monthly payments with an average interest rate of 6.34% maturing on March 4, 2024. Upon maturity, all interests in the subject equipment will revert back to the Company.

Tax Exempt Bonds

On July 2, 2020, the West Virginia Economic Development Authority (the “Issuer”) issued $53.1 million aggregate principal amount of Solid Waste Disposal Facility Revenue Bonds (Arch Resources Project), Series 2020 (the “Bonds”) pursuant to an Indenture of Trust dated as of June 1, 2020 (the “Indenture”) between the Issuer and Citibank, N.A., as trustee (the “Trustee”). The proceeds of the Bonds were loaned to the Company pursuant to a Loan Agreement dated as of June 1, 2020 between the Issuer and Arch. The Bonds are payable solely from payments to be made by the Company under the Loan Agreement as evidence by a Note from the Company to the Trustee. The proceeds of the Bonds were used to finance certain costs of the acquisition, construction, reconstruction, and equipping of solid waste disposal facilities at the Company’s Leer South development, and for capitalized interest and certain costs related to issuance of the Bonds.

20

The Bonds will bear interest payable each January 1 and July 1, commencing January 1, 2021, at an interest rate of 5% and have a final maturity of July 1, 2045; however, the Bonds are subject to mandatory tender on July 1, 2025 at a purchase price equal to 100% of the principal amount of the Bonds, plus accrued interest to July 1, 2025.

The Bonds are subject to redemption (i) in whole or in part at any time on or after January 1, 2025 at the option of the Issuer, upon the Company’s direction at a redemption price of par, plus interest accrued to the redemption date; and (ii) at par plus interest accrued to the redemption date from certain excess Bond proceeds as further described in the Indenture.

The Company’s obligations under the Loan Agreement are (i) except as otherwise described below, secured by first priority liens on and security interests in substantially all of the Company’s and Subsidiary Guarantors’ real property and other assets, subject to certain customary exceptions and permitted liens, and in any event excluding our accounts receivable and inventory; and (ii) jointly and severally guaranteed by the Subsidiary Guarantors, subject to customary exceptions.

The collateral securing the Company’s obligations under the Loan Agreement is substantially the same as the collateral securing the obligations under the Term Loan Debt Facility other than with respect to variances in certain real property collateral. The real property securing the Company’s obligations under the Loan Agreement includes a subset of the real property collateral securing the obligations under the Term Loan Debt Facility and includes only mortgages on substantially all of the Company’s revenue generating metallurgical coal real property and assets, including its mining complexes at Leer, Leer South, Mountain Laurel and Beckley in West Virginia. The Company is required to provide additional mortgages in the future to secure its obligations under the Loan Agreement due to the joint venture with Peabody not consummating.

The Loan Agreement contains certain affirmative covenants and representations, including but not limited to: (i) maintenance of a rating on the Bonds; (ii) maintenance of proper books of records and accounts; (iii) agreement to add additional guarantors to guarantee our obligations under the Loan Agreement in certain circumstances; (iv) procurement of customary insurance; and (v) preservation of legal existence and certain rights, franchises, licenses and permits. The Loan Agreement also contains certain customary negative covenants, which, among other things, and subject to certain exceptions, include restrictions on (i) release of collateral securing our obligations under the Loan Agreement; (ii) mergers and consolidations and disposition of assets, and (iii) restrictions on actions that may jeopardize the tax-exempt status of the Bonds.

The Loan Agreement contains customary events of default, subject to customary thresholds and exceptions, including, among other things, (i) nonpayment of principal, purchase price, interest and other fees (subject to certain cure periods), (ii) bankruptcy or insolvency proceedings relating to us; (iii) material inaccuracy of a representation or warranty at the time made, (iv) cross-events of default to indebtedness of at least $50 million, (v) cross defaults to the Indenture, the guaranty related to the Bonds or any related security documents.

As of September 30, 2020, Arch has received $38.1 million of the total bonds issues. The remaining $13.9 is held in trust and is recorded on the balance sheet as restricted cash. The remainder of the funds will be released as qualified expenditures are made over the next several quarters.

Interest Rate Swaps

The Company has entered into a series of interest rate swaps to fix a portion of the LIBOR interest rate within the term loan. The interest rate swaps qualify for cash flow hedge accounting treatment and as such, the change in the fair value of the interest rate swaps is recorded on the Company’s Condensed Consolidated Balance Sheet as an asset or liability with the effective portion of the gains or losses reported as a component of accumulated other comprehensive income and the ineffective portion reported in earnings. As interest payments are made on the term loan, amounts in accumulated other comprehensive income will be reclassified into earnings through interest expense to reflect a net interest on the term loan equal to the effective yield of the fixed rate of the swap plus 2.75% which is the spread on the revised LIBOR term loan. In the event that an interest rate swap is terminated prior to maturity, gains or losses in accumulated other comprehensive income will remain deferred and be reclassified into earnings in the periods which the hedged forecasted transaction affects earnings.

21

Below is a summary of the Company’s outstanding interest rate swap agreements designated as hedges as of September 30, 2020:

Notional Amount
(in millions)		Effective Date	Fixed Rate		Receive Rate	Expiration Date
$	200.0	June 30, 2020	2.249	%	1-month LIBOR	June 30, 2021
$	100.0	June 30, 2021	2.315	%	1-month LIBOR	June 30, 2023

The fair value of the interest rate swaps at September 30, 2020 is a liability of $4.5 million, which is recorded within Other noncurrent liabilities, with the offset to accumulated other comprehensive income on the Company’s Condensed Consolidated Balance Sheet. The Company realized $0.6 million and $1.5 million of losses during the three and nine months ended September 30, 2020, respectively, related to settlements of the interest rate swaps which was recorded to interest expense on the Company’s Condensed Consolidated Statement of Operations. The interest rate swaps are classified as Level 2 within the fair value hierarchy.

15. Income Taxes

A reconciliation of the federal income tax provision at the statutory rate to the actual provision for (benefit from) income taxes follows:

	Three Months Ended September 30,				Nine Months Ended September 30,
	2020		2019		2020		2019
	(In thousands)
Income tax provision at statutory rate	$	(40,128)	$	22,494	$	(55,922)	$	51,000

Other, net		—		—		—		(56)
Provision for (benefit from) income taxes	$	379	$	347	$	(206)	$	508

During the second quarter of 2020, the Company received a $37.4 million refund from the Internal Revenue Service consisting of all the remaining refundable alternative minimum tax (AMT) credits and related interest. A FIN48 reserve has been established for $13.3 million, which represents 40% of the portion of the refund that is subject to audit risk.

16. Fair Value Measurements

The hierarchy of fair value measurements assigns a level to fair value measurements based on the inputs used in the respective valuation techniques. The levels of the hierarchy, as defined below, give the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities and the lowest priority to unobservable inputs.

● Level 1 is defined as observable inputs such as quoted prices in active markets for identical assets. Level 1 assets include U.S. Treasury securities, and coal swaps and futures that are submitted for clearing on the New York Mercantile Exchange.

● Level 2 is defined as observable inputs other than Level 1 prices. These include quoted prices for similar assets or liabilities in an active market, quoted prices for identical assets and liabilities in markets that are not active, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities. The Company’s level 2 assets and liabilities include U.S. government agency securities, coal commodity contracts and interest rate swaps with fair values derived from quoted prices in over-the-counter markets or from prices received from direct broker quotes.

22

● Level 3 is defined as unobservable inputs in which little or no market data exists, therefore requiring an entity to develop its own assumptions. These include the Company’s commodity option contracts (coal, natural gas and heating oil) valued using modeling techniques, such as Black-Scholes, that require the use of inputs, particularly volatility, that are rarely observable. Changes in the unobservable inputs would not have a significant impact on the reported Level 3 fair values at September 30, 2020.

The table below sets forth, by level, the Company’s financial assets and liabilities that are recorded at fair value in the accompanying Condensed Consolidated Balance Sheet:

	September 30, 2020
	Total		Level 1		Level 2		Level 3
	(In thousands)
Assets:
Investments in marketable securities	$	63,128	$	15,306	$	47,822	$	—
Derivatives		2,665		2,560		105		—
Total assets	$	65,793	$	17,866	$	47,927	$	—
Liabilities:
Derivatives	$	4,545	$	—	$	4,545	$	—

The Company’s contracts with its counterparties allow for the settlement of contracts in an asset position with contracts in a liability position in the event of default or termination. For classification purposes, the Company records the net fair value of all the positions with these counterparties as a net asset or liability. Each level in the table above displays the underlying contracts according to their classification in the accompanying Condensed Consolidated Balance Sheet, based on this counterparty netting.

The following table summarizes the change in the fair values of financial instruments categorized as Level 3.

	Three Months Ended		Nine Months Ended
	September 30, 2020		September 30, 2020
	(In thousands)
Balance, beginning of period	$	33	$	61

Purchases		—		1,235
Issuances		—		(138)
Settlements		—		—
Ending balance	$	—	$	—

Net unrealized losses of $0.0 million and $0.2 million were recognized in the Condensed Consolidated Statement of Operations within Other operating income, net during the three and nine months ended September 30, 2020, respectively, related to Level 3 financial instruments held on September 30, 2020.

Fair Value of Long-Term Debt

At September 30, 2020 and December 31, 2019, the fair value of the Company’s debt, including amounts classified as current, was $356.7 million and $308.0 million, respectively. Fair values are based upon observed prices in an active market, when available, or from valuation models using market information, which fall into Level 2 in the fair value hierarchy.

17. Earnings per Common Share

The Company computes basic net income (loss) per share using the weighted average number of common shares outstanding during the period. Diluted net income (loss) per share is computed using the weighted average number of common shares and the effect of potentially dilutive securities outstanding during the period. Potentially dilutive securities may consist of warrants, restricted stock units or other contingently issuable shares. The dilutive effect of outstanding warrants, restricted stock units and other contingently issuable shares is reflected in diluted earnings per

23

share by application of the treasury stock method. The weighted average share impact of warrants and restricted stock units that were excluded from the calculation of diluted shares due to the Company incurring a net loss for the three and nine month periods ending September 30, 2020 were 178,333 shares and 169,555 shares, respectively.

	Three Months Ended September 30,		Nine Months Ended September 30,
	2020	2019	2020	2019
(In Thousands)
Weighted average shares outstanding:
Basic weighted average shares outstanding	15,147	15,736	15,144	16,591
Effect of dilutive securities	—	1,116	—	1,153
Diluted weighted average shares outstanding	15,147	16,852	15,144	17,744

The following table provides the basis for basic and diluted earnings per share by reconciling the denominators of the computations:

18. Workers Compensation Expense

The Company is liable under the Federal Mine Safety and Health Act of 1969, as subsequently amended, to provide for pneumoconiosis (occupational disease) benefits to eligible employees, former employees and dependents. The Company currently provides for federal claims principally through a self-insurance program. The Company is also liable under various state workers’ compensation statutes for occupational disease benefits. The occupational disease benefit obligation represents the present value of the actuarially computed present and future liabilities for such benefits over the employees’ applicable years of service.

In October 2019, the Company filed an application with the Office of Workers’ Compensation Programs (“OWCP”) within the Department of Labor for reauthorization to self-insure federal black lung benefits. In February 2020, the Company received a reply from the OWCP confirming Arch’s status to remain self-insured contingent upon posting additional collateral of $71.1 million within 30 days of receipt of the letter. The Company is currently appealing the ruling from the OWCP and has received an extension to self-insure during the appeal process. The Company is evaluating alternatives to self-insurance, including the purchase of commercial insurance to cover these claims.

In addition, the Company is liable for workers’ compensation benefits for traumatic injuries which are calculated using actuarially-based loss rates, loss development factors and discounted based on a risk free rate. Traumatic workers’ compensation claims are insured with varying retentions/deductibles, or through state-sponsored workers’ compensation programs.

Workers’ compensation expense consists of the following components:

	Three Months Ended September 30,				Nine Months Ended September 30,
	2020		2019		2020		2019
	(In thousands)
Self-insured occupational disease benefits:

Total workers’ compensation expense	$	5,617	$	5,112	$	17,074	$	15,712

(1)In accordance with the adoption of ASU 2017-07, “Compensation-Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost,” these costs are recorded within Nonoperating expenses in the Condensed Consolidated Statement of Operations on the line item “Non-service related pension and postretirement benefit costs.”

20. Commitments and Contingencies

The Company accrues for costs related to contingencies when a loss is probable and the amount is reasonably determinable. Disclosure of contingencies is included in the financial statements when it is at least reasonably possible that a material loss or an additional material loss in excess of amounts already accrued may be incurred.

In addition, the Company is a party to numerous other claims and lawsuits with respect to various matters. The ultimate resolution of any such legal matter could result in outcomes that may be materially different from amounts the Company has accrued for such matters. The Company believes it has recorded adequate reserves for these matters.

21. Segment Information

The Company’s reportable business segments are based on two distinct lines of business, metallurgical and thermal, and may include a number of mine complexes. The Company manages its coal sales by market, not by individual mining complex. Geology, coal transportation routes to customers, and regulatory environments also have a significant impact on the Company’s marketing and operations management. Mining operations are evaluated based on Adjusted EBITDA, per-ton cash operating costs (defined as including all mining costs except depreciation, depletion, amortization, accretion on asset retirement obligations, and pass-through transportation expenses), and on other non-financial measures, such as safety and environmental performance. Adjusted EBITDA is not a measure of financial performance in accordance with generally accepted accounting principles, and items excluded from Adjusted EBITDA are significant in understanding and assessing the Company’s financial condition. Therefore, Adjusted EBITDA should not be considered in isolation, nor as an alternative to net income (loss), income (loss) from operations, cash flows from operations or as a measure of our profitability, liquidity or performance under generally accepted accounting principles. The Company uses Adjusted EBITDA to measure the operating performance of its segments and allocate resources to the segments. Furthermore, analogous measures are used by industry analysts and investors to evaluate the Company’s operating performance. Investors should be aware that the Company’s presentation of Adjusted EBITDA may not be comparable to similarly titled measures used by other companies. The Company reports its results of operations primarily through the following

25

reportable segments: Powder River Basin (PRB) segment containing the Company’s primary thermal operations in Wyoming; the Metallurgical (MET) segment, containing the Company’s metallurgical operations in West Virginia, and the Other Thermal segment containing the Company’s supplementary thermal operations in Colorado and Illinois.

On December 13, 2019, the Company closed on its definitive agreement to sell Coal-Mac LLC, an operating mine complex within the Company’s Other Thermal coal segment. Coal-Mac is included in the Other Thermal segment results below up to the date of the divestiture.

26

Operating segment results for the three and nine months ended September 30, 2020 and 2019, are presented below. The Corporate, Other and Eliminations grouping includes these charges: idle operations; change in fair value of coal derivatives and coal trading activities, net; corporate overhead; land management activities; other support functions; and the elimination of intercompany transactions.

22. Revenue Recognition

ASC 606-10-50-5 requires that entities disclose disaggregated revenue information in categories (such as type of good or service, geography, market, type of contract, etc.) that depict how the nature, amount, timing, and uncertainty of revenue and cash flow are affected by economic factors. ASC 606-10-55-89 explains that the extent to which an entity’s revenue is disaggregated depends on the facts and circumstances that pertain to the entity’s contracts with customers and that some entities may need to use more than one type of category to meet the objective for disaggregating revenue.

In general, the Company’s business segmentation is aligned according to the nature and economic characteristics of its coal and customer relationships and provides meaningful disaggregation of each segment’s results. The Company has further disaggregated revenue between North America and Seaborne revenues which depicts the pricing and contract differences between the two. North America revenue is characterized by contracts that typically have a term of one year or longer and typically the pricing is fixed; whereas Seaborne revenue generally is derived by spot or short term contracts with pricing determined at the time of shipment or based on a market index.

As of September 30, 2020, the Company has outstanding performance obligations for the remainder of 2020 of 16.5 million tons of fixed price contracts and 1.0 million tons of variable price contracts. Additionally, the Company has outstanding performance obligations beyond 2020 of approximately 83.6 million tons of fixed price contracts and 5.0 million tons of variable price contracts.

23. Leases

The Company has operating and financing leases for mining equipment, office equipment, office space and transloading terminals with remaining lease terms ranging from less than one year to approximately seven years. Some of these leases include both lease and non-lease components which are accounted for as a single lease component as the Company has elected the practical expedient to combine these components for all leases. As most of the leases do not provide an implicit rate, the Company calculated the ROU assets and lease liabilities using its secured incremental borrowing rate at the lease commencement date.

Item 2.MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS.

Cautionary Notice Regarding Forward-Looking Statements

This report contains “forward-looking statements” - that is, statements related to future, not past, events. In this context, forward-looking statements often address our expected future business and financial performance, and often contain words such as “should,” “appears,” “expects,” “anticipates,” “intends,” “plans,” “believes,” “seeks,” or “will.” Forward-looking statements by their nature address matters that are, to different degrees, uncertain. For us, particular uncertainties arise from the COVID-19 pandemic, including its adverse effects on businesses, economies, and financial markets worldwide; from changes in the demand for our coal by the domestic electric generation and steel industries; from our ability to access the capital markets on acceptable terms and conditions; from legislation and regulations relating to the Clean Air Act and other environmental initiatives; from competition within our industry and with producers of competing energy sources; from our ability to successfully acquire or develop coal reserves; from operational, geological, permit, labor and weather-related factors; from the Tax Cuts and Jobs Act and other tax reforms; from the effects of foreign and domestic trade policies, actions or disputes; from fluctuations in the amount of cash we generate from operations, which could impact, among other things, our ability to pay dividends or repurchase shares in accordance with our announced capital allocation plan; from our ability to successfully integrate the operations that we acquire; from the impacts related to the termination of the proposed joint venture transaction with Peabody Energy Corporation; from our ability to generate significant revenue to make payments required by, and to comply with restrictions related to, our tax-exempt bonds; and from numerous other matters of national, regional and global scale, including those of a political, economic, business, competitive or regulatory nature. These uncertainties may cause our actual future results to be materially different than those expressed in our forward-looking statements. We do not undertake to update our forward-looking statements, whether as a result of new information, future events or otherwise, except as may be required by law. For a description of some of the risks and uncertainties that may affect our future results, you should see the “Risk Factors” in Item 1A of our Annual Report on Form 10-K for the year ended December 31, 2019 and subsequent Form 10-Q filings.

COVID-19

In the first quarter of 2020, COVID-19 emerged as a global level pandemic. The continuing responses to the COVID-19 outbreak include actions that have a significant impact on domestic and global economies, including travel restrictions, gathering bans, stay at home orders, and many other restrictive measures. All of our operations have been classified as essential in the states in which we operate. We have instituted many policies and procedures, in alignment with CDC guidelines and local mandates, to protect our employees during the COVID-19 outbreak. These policies and procedures include, but are not limited to, staggering shift times to limit the number of people in common areas at one time, limiting meetings and meeting sizes, continual cleaning and disinfecting of high touch and high traffic areas, including door handles, bath rooms, bath houses, access elevators, mining equipment, and other areas, limiting contractor access to our properties, limiting business travel, and instituting work from home for administrative employees. We plan to keep these policies and procedures in place and continually evaluate further enhancements for as long as necessary. We recognize that the COVID-19 outbreak and responses thereto will also impact both our customers and suppliers. To date, we have not had any significant issues with critical suppliers, and we continue to communicate with them and closely monitor their developments to ensure we have access to the goods and services required to maintain our operations and continue our Leer South development. Our customers have reacted, and continue to react, in various ways and to varying degrees to declining demand for their products. We have received force majeure letters from certain of our customers, primarily related to our thermal segments. During the current quarter, we concluded commercial negotiations with certain customers deferring over three million tons of Powder River Basin contractual obligations from 2020 to future periods in exchange for over eight million tons of additional commitments in future periods. Less than 0.2 million tons of domestic coking coal contracted for 2020 have been deferred to 2021. Our current view of our customer demand situation is discussed in greater detail in the “Overview” section below.

31

Overview

Our results for the third quarter of 2020 were impacted by continued weakness in metallurgical and thermal coal markets. Initial responses to the COVID-19 outbreak precipitated demand destruction that further weakened already depressed thermal and metallurgical coal markets. During the current quarter many of the initial responses to the COVID-19 outbreak were mitigated in certain areas of the national and global economy, stemming further decline in demand by the middle of the quarter.

The industrial shutdowns, particularly in the automotive sector, that drove significant reductions in steel demand and the idling of multiple blast furnaces globally, began to reverse in the third quarter, leading to increasing steel demand and the restarting of many idled blast furnaces. In particular, domestic auto production returned to pre-shutdown levels in July. The return of industrial production to pre-pandemic levels has been, and will continue to be uneven; for example, oil and gas drilling activity remains significantly depressed. The return of industrial production to pre-COVID-19 levels is also likely to be lengthy and subject to possible setbacks should COVID-19 become resurgent. Demand for steel making raw materials, like coking coal, are at the end of the supply chain and saw a lag in improved demand from the ramp up of industrial production. By the end of the quarter, international prompt and forward coking coal pricing had improved from lows experienced in the current quarter. On the supply side, further high cost coking coal mine idlings were announced in North America and the overall production volume removed from the market this year is significant. We believe that the cash cost of a significant portion of global seaborne coking coal production, including much of North American coking coal production, exceeds current prompt pricing. To date, due to our low cost structure, we have avoided idling any of our coking coal operations. Longer term, we believe continued limited global capital investment in new coking coal production capacity, economic pressure on higher cost production sources, and production responses to the virus outbreak will provide support to coking coal markets as demand continues to return to the steel production supply chain.

Demand for domestic thermal coal improved in the current quarter from lows in the first half of the year due to the anticipated summer cooling season demand, favorable weather during this cooling season, and increased natural gas prices. However, demand levels remain significantly below those in the prior year due to COVID-19 related commercial and industrial demand declines and the continued increase in renewable generation sources, particularly wind. Natural gas pricing recovered from historically low levels during the current quarter, and coal fired generation, particularly Powder River Basin fired generation, was competitive in many regions of the country during the peak cooling season. Production levels of natural gas were below the prior year’s levels, but storage levels remain significantly above this time last year. Additionally, generator coal stockpiles declined during the current quarter, but remain significantly above historical averages based on days of burn. International thermal coal market pricing remained at levels that are uneconomic for all of our thermal operations. Similar to metallurgical markets discussed above, actions taken to combat the spread of COVID-19 across many regions of the national and global economy continue to negatively impact thermal coal demand and supply. As a result, we expect domestic and global thermal markets to remain challenged.

On September 29, 2020 the U.S. District Court ruled against our proposal with Peabody to form a joint venture that would have combined our Powder River Basin and Colorado mining operations with Peabody’s. Following the ruling, we announced the termination of our joint venture efforts due to the significant investment of time, resources and funds that would be required to conduct an appeal. In light of the unfavorable ruling and decision to terminate efforts on the joint venture, we will pursue other strategic alternatives for our thermal assets. These alternatives include, among other things, potential divestiture. We will concurrently evaluate opportunities to shrink our operational footprint at those mines, reduce their asset retirement obligations, and establish self-funding mechanisms to address those long-term liabilities. Operationally we will maintain our focus on aligning our thermal production rates with declining domestic thermal coal demand, adjusting our thermal operating plans in order to minimize future cash requirements, and streamlining our entire organizational structure to reflect our long-term strategic direction as a leading producer of metallurgical products for the steelmaking industry.

Results of Operations

Three Months Ended September 30, 2020 and 2019

Revenues. Our revenues include sales to customers of coal produced at our operations and coal purchased from third parties. Transportation costs are included in cost of coal sales and amounts billed by us to our customers for transportation are included in revenues.

Coal Sales. The following table summarizes information about our coal sales during the three months ended September 30, 2020 and 2019:

	Three Months Ended September 30,
	2020		2019		(Decrease) / Increase
	(In thousands)
Coal sales	$	382,261	$	619,467	$	(237,206)
Tons sold		17,128		26,257		(9,129)

On a consolidated basis, coal sales in the third quarter of 2020 were approximately $237.2 million or 38.3% less than in the third quarter of 2019, while tons sold decreased approximately 9.1 million tons or 34.8%. Coal sales from Metallurgical operations decreased approximately $86.4 million due to decreased pricing and volume. Powder River Basin coal sales decreased approximately $89.1 million due to decreased volume, and Other Thermal coal sales decreased approximately $61.6 million due to decreased volume and pricing. In the prior year quarter, our Coal-Mac operation in our Other Thermal Segment, which was sold in December 2019, provided approximately $30.8 million in coal sales and 0.6 million tons sold. See discussion in “Operational Performance” for further information about segment results.

Costs, expenses and other. The following table summarizes costs, expenses and other components of operating income during the three months ended September 30, 2020 and 2019:

	Three Months Ended September 30,
	2020		2019		Increase (Decrease) in Net Income

Total costs, expenses and other	$	569,941	$	512,986	$	(56,955)

Cost of sales. Our cost of sales for the third quarter of 2020 decreased approximately $145.5 million or 29.6% versus the third quarter of 2019. In the prior year quarter, our Coal-Mac operation, which was sold in December 2019, accounted for approximately $30.8 million in cost of sales. The decline in cost of sales at ongoing operations consists primarily of reduced repairs and supplies costs of approximately $59.5 million, including approximately $12.8 million in reduced diesel fuel costs, reduced transportation costs of approximately $25.0 million, reduced operating taxes and royalties of approximately $27.0 million, and reduced compensation costs of approximately $6.9 million. These cost decreases were partially offset by a larger decrease in coal inventory value versus the prior year quarter of approximately $3.7 million. See discussion in “Operational Performance” for further information about segment results.

33

Depreciation, depletion, and amortization. The increase in depreciation, depletion, and amortization in the third quarter of 2020 versus the third quarter of 2019 is primarily due to increased depreciation of plant and equipment and amortization of development in our Metallurgical segment.

Change in fair value of coal derivatives and coal trading activities, net. The cost in both the third quarter of 2020 and 2019 is primarily related to mark-to-market losses on coal derivatives that we had entered into to hedge our price risk for anticipated international thermal coal shipments.

Selling, general and administrative expenses. Selling, general and administrative expenses in the third quarter of 2020 decreased versus the third quarter of 2019 due primarily to decreased compensation costs of approximately $3.7 million, which includes the impact of reduced headcount from our voluntary separation program recognized in the first quarter of 2020, partially offset by increased contractor services of approximately $0.9 million.

Costs related to proposed joint venture with Peabody Energy. On June 18, 2019, we entered into a definitive implementation agreement (the “Implementation Agreement”) with Peabody, to establish a joint venture that would have combined the companies’ Powder River Basin and Colorado mining operations. All costs associated with execution of the Implementation Agreement are reflected herein. On September 29, 2020 the U.S. District Court for the Eastern District of Missouri ruled against the proposed joint venture, and we announced the termination of our joint venture efforts due to the significant investment of time, resources and investment that would be required to conduct an appeal. For further information on our proposed joint venture with Peabody Energy, see Note 3, “Joint Venture with Peabody Energy” to the Condensed Consolidated Financial Statements.

Asset Impairment. In the third quarter of 2020 we determined that we had indicators of impairment related to three of our thermal operations, Coal Creek, West Elk, and Viper. Additionally, we determined that we had indicators of impairment related to our equity investment in Knight Hawk Holdings LLC. Our analyses of future expected cash flows from these assets indicated full impairment of our listed thermal operations and partial impairment of our equity investment in Knight Hawk Holdings LLC. For further information on our Asset Impairment costs, see Note 8, “Asset Impairment” to the Condensed Consolidated Financial Statements.

Preference Rights Lease Application (PRLA) settlement income.  Our PRLA settlement income in the third quarter of 2019 relates to a settlement with the United States Department of Interior over a long-standing dispute on the valuation and disposition of PRLAs that we controlled in northwestern New Mexico. For further information on our PRLA settlement income see Note 7, “Preference Rights Lease Application Settlement Income” to the Condensed Consolidated Financial Statements.

Other operating income, net. The increase in other operating income, net in the third quarter of 2020 versus the third quarter of 2019 consists primarily of the favorable impact of mark-to-market movement on heating oil derivatives of approximately $1.5 million and increased income from equity investments of approximately $0.9 million, partially offset by the unfavorable impact of certain coal derivative settlements of approximately $0.6 million and reduced transloading income of approximately $1.0 million.

Nonoperating (expenses) income. The following table summarizes our nonoperating (expenses) income during the three months ended September 30, 2020 and 2019:

	Three Months Ended September 30,
	2020		2019		Increase (Decrease) in Net Income
	(In thousands)
Non-service related pension and postretirement benefit (costs) credits	$	(878)	$	975	$	(1,853)

Non-service related pension and postretirement benefit costs. The cost in non-service related pension and postretirement benefit costs in the third quarter of 2020 versus the benefit in the third quarter of 2019 is primarily due to increased postretirement benefit gain amortization in the third quarter of 2019.

34

Provision for income taxes. The following table summarizes our provision for income taxes during the three months ended September 30, 2020 and 2019:

	Three Months Ended September 30,
	2020		2019		Increase (Decrease) in Net Income
	(In thousands)
Provision for income taxes	$	379	$	347	$	(32)

On a consolidated basis, coal sales in the first nine months of 2020 were approximately $637.9 million or 36.6% less than in the first nine months of 2019, while tons sold decreased approximately 20.6 million tons or 30.3%. Coal sales from Metallurgical operations decreased approximately $279.3 million due to decreased volume and pricing. Powder River Basin coal sales decreased approximately $200.4 million due to decreased volume, and Other Thermal coal sales decreased approximately $172.8 million due to decreased volume and pricing. In the prior year period, our Coal-Mac operation in our Other Thermal Segment, which was sold in December 2019, provided approximately $85.8 million in coal sales and 1.6 million tons sold. See discussion in “Operational Performance” for further information about segment results.

Costs, expenses and other. The following table summarizes costs, expenses and other components of operating income during the nine months ended September 30, 2020 and 2019:

Total costs, expenses and other	$	1,363,871	$	1,495,042	$	131,171

Cost of sales. Our cost of sales for the first nine months of 2020 decreased approximately $343.7 million or 24.9% versus the first nine months of 2019. In the prior year period, our Coal-Mac operation, which was sold in December 2019, accounted for approximately $85.3 million in cost of sales. The decline in cost of sales at ongoing operations consists primarily of reduced repairs and supplies costs of approximately $139.3 million, including approximately $28.0 million in reduced diesel fuel costs, reduced transportation costs of approximately $67.9 million, reduced operating taxes and royalties of approximately $62.1 million, and reduced compensation costs of approximately $15.0 million. These cost decreases were partially offset by a smaller increase in coal inventory value versus the prior year period of

36

approximately $16.8 million, and increased purchased coal cost of approximately $14.5 million. See discussion in “Operational Performance” for further information about segment results.

Depreciation, depletion, and amortization. The increase in depreciation, depletion, and amortization in the first nine months of 2020 versus the first nine months of 2019 is primarily due to increased depreciation of plant and equipment, amortization of development, and depletion in our Metallurgical segment.

Change in fair value of coal derivatives and coal trading activities, net. The significant benefit in the first nine months of 2019 is primarily related to mark-to-market gains on coal derivatives that we had entered to hedge our price risk for anticipated international thermal coal shipments.

Selling, general and administrative expenses. Selling, general and administrative expenses in the first nine months of 2020 decreased versus the first nine months of 2019 due primarily to decreased compensation costs of approximately $10.2 million, which includes the impact of reduced headcount from our voluntary separation program recognized in the first quarter of 2020.

Costs related to proposed joint venture with Peabody Energy. On June 18, 2019, we entered into a definitive implementation agreement (the “Implementation Agreement”) with Peabody, to establish a joint venture that would have combined the companies’ Powder River Basin and Colorado mining operations. All costs associated with execution of the Implementation Agreement are reflected herein. On September 29, 2020 the U.S. District Court for the Eastern District of Missouri ruled against the proposed joint venture, and we announced the termination of our joint venture efforts due to the significant investment of time, resources and investment that would be required to conduct an appeal. For further information on our proposed joint venture with Peabody Energy, see Note 3, “Joint Venture with Peabody Energy” to the Condensed Consolidated Financial Statements.

Asset Impairment. In the third quarter of 2020 we determined that we had indicators of impairment related to three of our thermal operations, Coal Creek, West Elk, and Viper. Additionally, we determined we had indicators of impairment related to our equity investment in Knight Hawk Holdings LLC. Our analyses of future expected cash flows from these assets indicted full impairment of our listed thermal operations and partial impairment of our equity investment in Knight Hawk Holdings LLC. For further information on our Asset Impairment costs, see Note 8, “Asset Impairment” to the Condensed Consolidated Financial Statements.

Severance costs related to voluntary separation plan (VSP). In the current year period we recorded approximately $13.3 million of employee severance expense related to voluntary separation plans that were accepted by 53 employees of the corporate staff and 201 employees of our thermal operations. For further information on our VSP costs see Note 5, “Severance Costs Related to Voluntary Separation Plan” to the Condensed Consolidated Financial Statements.

Gain on property insurance recovery related to Mountain Laurel longwall. In the current year period we recorded a $23.5 million benefit from insurance proceeds related to the loss of certain longwall shields at our Mountain Laurel operation in November of 2019. For further information on our gain on property insurance recovery related to Mountain Laurel longwall, see Note 4, “Gain on Property Insurance Recovery Related to Mountain Laurel Longwall” to the Condensed Consolidated Financial Statements.

(Gain) loss on divestitures. In the current year period we recorded a $1.4 million gain on the sale of our idle Dal-Tex and Briar Branch properties. In the prior year period we recorded a loss on our sale of Lone Mountain Processing, LLC related to certain workers’ compensation liabilities that may accrue to us as a result of the bankruptcy filing of Revelation Energy LLC. For further information on this gain and loss, see Note 6, “Divestitures” to the Condensed Consolidated Financial Statements.

Other operating income, net. The increase in other operating income, net in the first nine months of 2020 versus the first nine months of 2019 consists primarily of the favorable impact of certain coal derivative settlements of approximately $9.0 million, increased outlease royalty income of 1.6 million, and increased income from equity investments of approximately $1.7 million, partially offset by reduced transloading income of approximately $2.5 million and a gain on sale of certain right of way rights in the prior year period of approximately $2.3 million.

Operational Performance

Three and Nine Months Ended September 30, 2020 and 2019

Our mining operations are evaluated based on Adjusted EBITDA, per-ton cash operating costs (defined as including all mining costs except depreciation, depletion, amortization, accretion on asset retirements obligations, and pass-through transportation expenses), and on other non-financial measures, such as safety and environmental performance. Adjusted EBITDA is defined as net income (loss) attributable to the Company before the effect of net interest expense, income taxes, depreciation, depletion and amortization, the accretion on asset retirement obligations and nonoperating expenses. Adjusted EBITDA may also be adjusted for items that may not reflect the trend of future results by excluding transactions that are not indicative of our core operating performance. Adjusted EBITDA is not a measure of financial performance in accordance with generally accepted accounting principles, and items excluded from Adjusted EBITDA are significant in understanding and assessing our financial condition. Therefore, Adjusted EBITDA should not be considered in isolation, nor as an alternative to net income (loss), income (loss) from operations, cash flows from operations or as a measure of our profitability, liquidity or performance under generally accepted accounting principles. Furthermore, analogous measures are used by industry analysts and investors to evaluate the Company’s operating performance. Investors should be aware that our presentation of Adjusted EBITDA may not be comparable to similarly titled measures used by other companies.

The following table shows results by operating segment for the three and nine months ended September 30, 2020 and September 30, 2019.

This table reflects numbers reported under a basis that differs from U.S. GAAP. See “Reconciliation of Non-GAAP measures” below for explanation and reconciliation of these amounts to the nearest GAAP measures. Other companies may calculate these per ton amounts differently, and our calculation may not be comparable to other similarly titled measures.

Powder River Basin — Adjusted EBITDA for the three and nine months ended September 30, 2020 decreased versus the three and nine months ended September 30, 2019, due to decreased volume versus the prior year periods. Pricing increased, and cash cost per ton sold increased, particularly in the nine month period, driven by the decrease in

39

volume and the reimposition of a higher Federal Black Lung Excise Tax rate. Pricing in the current periods benefitted from our ability to recoup the reimposition of the higher Federal Black Lung Excise Tax rate under certain of our term supply contracts. The volume decline was primarily due to competitive natural gas pricing, and the continued growth of renewable generation sources, particularly wind. Natural gas pricing reached historical lows during the current year periods, but pricing of the competing fuel was volatile in the current year three month period even exceeding prior year prices at times. Natural gas production levels fell below prior year levels, but natural gas storage levels remained above prior year levels and these opposing market forces led to pricing volatility. The continued buildout of subsidized renewable generation sources, particularly wind, significantly increased the market share of renewable generation in the current year periods. During the current year periods, we also experienced reduced electric generation related to demand destruction due to restrictive responses taken to combat the spread of COVID-19. During the current year three month period, generator stockpiles of thermal coal declined from historical highs seen earlier in the current year, but remain above historical averages in terms of days of burn. Our Powder River Basin shipment volumes will continue to be pressured as natural gas prices remain competitive, subsidized renewable generation continues to grow, and thermal coal stockpiles remain elevated. Additionally, we are at risk of further demand destruction should a resurgence of COVID-19 lead to the imposition of economically damaging responses to control the spread of the virus.

In 2019 the Federal Black Lung Excise Tax rate reverted to the pre-1986 rates. For 2020, Congress reimposed the higher 1986 to 2018 rates of $0.55 per ton sold or 4.4% of gross selling price on all domestic sales. For 2019, the Federal Black Lung Excise Tax rate for surface mines was $0.25 per ton or 2% of gross selling price on all domestic sales.

Metallurgical — Adjusted EBITDA for the three and nine months ended September 30, 2020 decreased from the three and nine months ended September 30, 2019 due to the decline in coking coal pricing and shipment volume discussed in the “Overview” section above, partially offset by decreased cash cost per ton sold. The cost decrease was driven by an increase in the percentage of segment tons sold from our low cost Leer mine in the current year periods. Additionally, operating tax and royalty costs declined in the current year periods due to lower pricing and a severance tax credit. Actions taken to combat the spread of COVID-19 continued to significantly impact our metallurgical segment in the third quarter of 2020. In particular, the initial industrial shutdowns and subsequent uneven recovery discussed in the “Overview” section above continued to have a negative impact on the entire steel making supply chain. These impacts include a significant decline in coking coal pricing and deferral of some shipments out of the current year.

Our Metallurgical segment sold 1.7 million tons of coking coal and 0.3 million tons of associated thermal coal in the three months ended September 30, 2020, compared to 1.9 million tons of coking coal and 0.2 million tons of associated thermal coal in the three months ended September 30, 2019. For the nine months ended September 30, 2020, our Metallurgical segment sold 4.5 million tons of coking coal and 0.7 million tons of associated thermal coal compared to 5.0 million tons of coking coal and 0.8 million tons of associated thermal coal in the nine months ended September 30, 2019. Longwall operations accounted for approximately 60% of our shipment volume in both the three and nine months ended September 30, 2020, respectively, compared to approximately 78% and 72% of our shipment volume in the three and nine months ended September 30, 2019, respectively.

Other Thermal — Adjusted EBITDA for the three and nine months ended September 30, 2020 decreased versus the three and nine months ended September 30, 2019 due to reduced sales volume, decreased pricing, and increased cash cost per ton sold. All of these metrics are impacted by the inclusion of our former Coal-Mac operation, which was sold in December 2019. Coal-Mac provided approximately 0.6 and 1.6 million tons sold in the three and nine months ended September 30, 2019, respectively. Tons sold from ongoing operations declined approximately 0.6 million tons in the three months ended September 30, 2020 and 1.4 million tons in the nine months ended September 30, 2020 as competitive natural gas pricing, increased renewable generation, and uneconomic international pricing impacted volume. In addition, in late March of the current year we temporarily idled our Viper mine due to nonperformance of the mine’s primary customer. The customer restarted deliveries in early May, and we reopened the mine at approximately the same time. We are at risk of further demand destruction should a resurgence of COVID-19 lead to the imposition of economically damaging responses to control the spread of the virus.

Reconciliation of Non-GAAP measures

Segment coal sales per ton sold

Non-GAAP Segment coal sales per ton sold is calculated as segment coal sales revenues divided by segment tons sold. Segment coal sales revenues are adjusted for transportation costs, and may be adjusted for other items that, due to generally accepted accounting principles, are classified in “other income” on the statement of operations, but relate to price protection on the sale of coal. Segment coal sales per ton sold is not a measure of financial performance in accordance with generally accepted accounting principles. We believe segment coal sales per ton sold provides useful information to investors as it better reflects our revenue for the quality of coal sold and our operating results by including all income from coal sales. The adjustments made to arrive at these measures are significant in understanding and assessing our financial condition. Therefore, segment coal sales revenues should not be considered in isolation, nor as an alternative to coal sales revenues under generally accepted accounting principles.

Segment cash cost per ton sold

Non-GAAP Segment cash cost per ton sold is calculated as segment cash cost of coal sales divided by segment tons sold. Segment cash cost of coal sales is adjusted for transportation costs, and may be adjusted for other items that, due to generally accepted accounting principles, are classified in “other income” on the statement of operations, but relate directly to the costs incurred to produce coal. Segment cash cost per ton sold is not a measure of financial performance in accordance with generally accepted accounting principles. We believe segment cash cost per ton sold better reflects our controllable costs and our operating results by including all costs incurred to produce coal. The adjustments made to arrive at these measures are significant in understanding and assessing our financial condition. Therefore, segment cash cost of coal sales should not be considered in isolation, nor as an alternative to cost of sales under generally accepted accounting principles.

Reconciliation of Segment Adjusted EBITDA to Net Income (Loss)

The discussion in “Results of Operations” above includes references to our Adjusted EBITDA for each of our reportable segments. Adjusted EBITDA is defined as net income attributable to the Company before the effect of net interest expense, income taxes, depreciation, depletion and amortization, the accretion on asset retirement obligations and nonoperating expenses. Adjusted EBITDA may also be adjusted for items that may not reflect the trend of future results by excluding transactions that are not indicative of our core operating performance. We use Adjusted EBITDA to measure the operating performance of our segments and allocate resources to our segments. Adjusted EBITDA is not a measure of financial performance in accordance with generally accepted accounting principles, and items excluded from Adjusted EBITDA are significant in understanding and assessing our financial condition. Therefore, Adjusted EBITDA should not be considered in isolation, nor as an alternative to net income (loss), income (loss) from operations, cash flows from operations or as a measure of our profitability, liquidity or performance under generally accepted accounting principles. Investors should be aware that our presentation of Adjusted EBITDA may not be comparable to similarly titled measures used by other companies. The table below shows how we calculate Adjusted EBITDA.

Liquidity and Capital Resources

Our primary sources of liquidity are proceeds from coal sales to customers and certain financing arrangements. Excluding significant investing activity, we intend to satisfy our working capital requirements and fund capital expenditures and debt-service obligations with cash generated from operations and cash on hand. As we continue to evaluate the impacts of COVID-19 and the responses thereto on our business, we remain focused on prudently managing costs, including capital expenditures, maintaining a strong balance sheet, and ensuring adequate liquidity.

Given the volatile nature of coal markets, and the significant challenges and uncertainty surrounding the COVID-19 outbreak, we believe it is increasingly important to take a prudent approach to managing our balance sheet and liquidity, as demonstrated by the suspension of our dividend and share repurchases. While we continue to prefer targeted liquidity levels of at least $400 million, with a significant portion of that being cash, it is likely that our liquidity will remain below our preferred levels while the COVID-19 outbreak and the responses thereto continue. Due to the current economic uncertainties related to COVID-19 and the related disruption in the financial markets, we may be limited in accessing capital markets or obtaining additional bank financing or the cost of accessing this financing could become more expensive. We believe our current liquidity level is sufficient to fund our business; however, given the uncertainty in the global economy and our primary markets, we believe it is prudent to explore opportunities to secure additional capital to further enhance our liquidity position as we drive forward with our Leer South development. In the future, we will continue to evaluate our capital allocation initiatives in light of the current state of, and our outlook, for coal markets; the amount of our planned production that has been committed and priced; the capital needs of the business; other strategic opportunities; and developments in the COVID-19 outbreak and the responses thereto.

On March 7, 2017, we entered into a senior secured term loan credit agreement in an aggregate principal amount of $300 million (the “Term Loan Debt Facility”) with Credit Suisse AG, Cayman Islands Branch, as administrative agent and collateral agent and the other financial institutions from time to time party thereto. The Term Loan Debt Facility was issued at 99.50% of the face amount and will mature on March 7, 2024. The term loans provided under the Term Loan Debt Facility (the “Term Loans”) are subject to quarterly principal amortization payments in an amount equal to $750,000. Proceeds from the Term Loan Debt Facility were used to repay all outstanding obligations under our previously existing term loan credit agreement, dated as of October 5, 2016.

On April 3, 2018, we entered into the Second Amendment (the “Second Amendment”) to the Term Loan Debt Facility. The Second Amendment reduced the interest rate on the Term Loan to, at our option, either (i) the London interbank offered rate (“LIBOR”) plus an applicable margin of 2.75%, subject to a 1.00% LIBOR floor, or (ii) a base rate plus an applicable margin of 1.75%. For further information regarding the Term Loan Debt Facility, see Note 14, “Debt and Financing Arrangements” to the Condensed Consolidated Financial Statements.

We have entered into a series of interest rate swaps to fix a portion of the LIBOR interest payments due under the term loan. As interest payments are made on the term loan, amounts in accumulated other comprehensive income will be reclassified into earnings through interest expense to reflect a net interest on the term loan equal to the effective yield of the fixed rate of the swap plus 2.75%, which is the spread on the LIBOR term loan as amended. For further information regarding the interest rate swaps, see Note 14, “Debt and Financing Arrangements” to the Condensed Consolidated Financial Statements.

On September 30, 2020, we extended and amended our existing trade accounts receivable securitization facility provided to Arch Receivable Company, LLC, a special-purpose entity that is a wholly owned subsidiary of Arch Resources (“Arch Receivable”) (the “Extended Securitization Facility”), which supports the issuance of letters of credit and requests for cash advances. The amendment to the Extended Securitization Facility changed the facility size from $160 million to $110 million and extended the maturity date to September 29, 2023. Additionally, the amendment eliminated the provision that accelerated maturity of the facility upon falling below a specified level of liquidity and modified the pricing for the Extended Securitization Facility. Pursuant to the Extended Securitization Facility, we also agreed to a revised schedule of fees payable to the administrator and the providers of the Extended Securitization Facility. For further information regarding the Extended Securitization Facility see Note 14, “Debt and Financing Arrangements” to the Condensed Consolidated Financial Statements.

On September 30, 2020, we amended the senior secured inventory-based revolving credit facility in an aggregate principal amount of $50 million (the “Inventory Facility”) with Regions Bank (“Regions”) as administrative agent and collateral agent, as lender and swingline lender (in such capacities, the “Lender”) and as letter of credit issuer. Availability under the Inventory Facility is subject to a borrowing base consisting of (i) 85% of the net orderly liquidation value of eligible coal inventory, (ii) the lesser of (x) 85% of the net orderly liquidation value of eligible parts and supplies inventory and (y) 35% of the amount determined pursuant to clause (i), and (iii) 100% of Arch Resources’s Eligible Cash (defined in the Inventory Facility), subject to reduction for reserves imposed by Regions. The amendment of the Inventory Facility extended the maturity date to September 29, 2023, eliminated the provision that accelerated maturity of the facility upon falling below a specified level of liquidity, and reduced the minimum liquidity requirement from $175 million to $100 million. Additionally, the amendment includes provisions that reduce the advance rates for coal inventory and parts and supplies, depending on Liquidity. For further information regarding the Inventory Facility, see Note 14, “Debt and Financing Arrangements” to the Condensed Consolidated Financial Statements.

On March 4, 2020, we entered into an equipment financing arrangement accounted for as debt. We received $53.6 million in exchange for conveying an interest in certain equipment in operation at our Leer Mine and entered into a 48 month master lease arrangement for use of that equipment. Upon maturity, all interests in the equipment will revert back to us. For further information regarding this equipment financing arrangement, see Note 14, “Debt and Financing Arrangements” to the Condensed Consolidated Financial Statements.

On July 2, 2020, the West Virginia Economic Development Authority (the “Issuer”) issued $53.1 million aggregate principal amount of Solid Waste Disposal Facility Revenue Bonds (Arch Resources Project), Series 2020 (the “Bonds”) pursuant to an Indenture of Trust dated as of June 1, 2020 (the “Indenture”) between the Issuer and Citibank, N.A., as trustee (the “Trustee”). The proceeds of the Bonds are loaned to us as we make qualifying expenditures pursuant to a Loan Agreement dated as of June 1, 2020 between the Issuer and us. The Bonds are payable solely from payments to be made by us under the Loan Agreement as evidenced by a Note from us to the Trustee. The proceeds of the Bonds were used to finance certain costs of the acquisition, construction, reconstruction, and equipping of solid waste disposal facilities at our Leer South development, and for capitalized interest and certain costs related to issuance of the Bonds. As of September 30, 2020, we have received $38.1 million of the total bonds issues. The remaining $13.9 is held in trust and is recorded on our balance sheet as restricted cash. The remainder of the funds will be released as qualified expenditures are made over the next several quarters. For further information regarding these bonds, see Note 14, “Debt and Financing Arrangements” to the Condensed Consolidated Financial Statements.

On April 27, 2017, our Board of Directors authorized a capital return program consisting of a share repurchase program and a quarterly cash dividend. The share repurchase plan has a total authorization of $1.05 billion of which we have used $827.4 million. During the quarter ended September 30, 2020, we did not repurchase any shares of our stock. On April 23, 2020 we announced the suspension of our quarterly dividend due to the significant economic uncertainty surrounding the COVID-19 virus and the steps being taken to control the virus. During the quarter ended September 30, 2020, we did not pay any dividends on shares of our stock. The timing and amount of any future dividends or of any future share purchases and the ultimate number of shares to be purchased will depend on a number of factors, including business and market conditions, our future financial performance, and other capital priorities. Any shares acquired would be in the open market or through private transactions in accordance with Securities and Exchange Commission requirements.

On September 30, 2020 we had total liquidity of approximately $265 million including $220 million in unrestricted cash and equivalents, and short term investments in debt securities, with the remainder provided by availability under our credit facilities, and funds withdrawable from brokerage accounts. The table below summarizes our availability under our credit facilities as of September 30, 2020:

The above standby letters of credit outstanding have primarily been issued to satisfy certain insurance-related collateral requirements. The amount of collateral required by counterparties is based on their assessment of our ability to satisfy our obligations and may change at the time of policy renewal or based on a change in their assessment. Future increases in the amount of collateral required  by counterparties would reduce our available liquidity.

The following is a summary of cash provided by or used in each of the indicated types of activities during the nine months ended September 30, 2020 and 2019:

	Nine Months Ended September 30,
	2020		2019
(In thousands)
Cash provided by (used in):
Operating activities	$	55,914	$	334,053
Investing activities		(111,945)		(154,002)
Financing activities		73,585		(269,560)

Cash Flow

Cash provided by operating activities decreased in the nine months ended September 30, 2020 versus the nine months ended September 30, 2019 mainly due to the deterioration of results from operations discussed in the “Overview” and “Operational Performance” sections above.

Cash used in investing activities decreased in the nine months ended September 30, 2020 versus the nine months ended September 30, 2019 primarily due to an approximately $84 million increase in net proceeds from short term investments, and approximately $24 million in property insurance proceeds on our Mountain Laurel longwall claim, partially offset by increased capital expenditures of approximately $68 million. Capital spending in the first nine months of 2020 includes approximately $154 million related to our Leer South mine development.  

Cash was provided by financing activities in the nine months ended September 30, 2020 compared to cash used in financing activities in the nine months ended September 30, 2019 primarily due to suspension of treasury stock purchases and dividend payments, and proceeds from the new $54 million equipment financing arrangement, and proceeds of approximately $53 million from the new tax exempt bond issuance. For further information regarding the equipment financing arrangement and tax free bonds, see Note 14, “Debt and Financing Arrangements” to the Condensed Consolidated Financial Statements.

Item 3.Quantitative and Qualitative Disclosures About Market Risk.

We manage our commodity price risk for our non-trading, thermal coal sales through the use of long-term coal supply agreements, and to a limited extent, through the use of derivative instruments. Sales commitments in the metallurgical coal market are typically not long term in nature, and we are therefore subject to fluctuations in market pricing.

Our sales commitments for 2020 and 2021 were as follows as of October 22, 2020:

	2020			2021
	Tons	$ per ton		Tons	$per ton
Metallurgical	(in millions)			(in millions)

Committed, Unpriced	0.1			—

We are also exposed to commodity price risk in our coal trading activities, which represents the potential future loss that could be caused by an adverse change in the market value of coal. Our coal trading portfolio included swap and put and call option contracts at September 30, 2020. The estimated future realization of the value of the trading portfolio is $0.2 million of losses during the remainder of 2020 and $0.3 million of gains during 2021.

We monitor and manage market price risk for our trading activities with a variety of tools, including Value at Risk (VaR), position limits, management alerts for mark to market monitoring and loss limits, scenario analysis, sensitivity analysis and review of daily changes in market dynamics. Management believes that presenting high, low, end of year and average VaR is the best available method to give investors insight into the level of commodity risk of our trading positions. Illiquid positions, such as long-dated trades that are not quoted by brokers or exchanges, are not included in VaR.

VaR is a statistical one-tail confidence interval and down side risk estimate that relies on recent history to estimate how the value of the portfolio of positions will change if markets behave in the same way as they have in the recent past. The level of confidence is 95%. The time across which these possible value changes are being estimated is through the end of the next business day. A closed-form delta-neutral method used throughout the finance and energy sectors is employed to calculate this VaR. VaR is back tested to verify its usefulness. As of September 30, 2020, VaR was immaterial to the financial statements.

We are exposed to price risk with respect to diesel fuel purchased for use in our operations. We anticipate purchasing approximately 30 to 35 million gallons of diesel fuel for use in our operations annually. To protect our cash flows from increases in the price of diesel fuel for our operations, we use forward physical diesel purchase contracts, purchased heating oil call options and New York Mercantile Exchange (“NYMEX”) gulf coast diesel swaps and options. At September 30, 2020, we had protected the price on the majority of our expected diesel fuel purchases for the remainder of 2020 with approximately 2 million gallons of heating oil call options with an average strike price of $1.76 per gallon and 2 million gallons of NYMEX gulf coast diesel swaps at an average price of approximately $1.05 per

49

gallon. These positions are not designated as hedges for accounting purposes, and therefore, changes in the fair value are recorded immediately to earnings.

Item 4.Controls and Procedures.

We performed an evaluation under the supervision and with the participation of our management, including our chief executive officer and chief financial officer, of the effectiveness of the design and operation of our disclosure controls and procedures as of September 30, 2020. Based on that evaluation, our management, including our chief executive officer and chief financial officer, concluded that the disclosure controls and procedures were effective as of such date. There were no changes in our internal control over financial reporting during the fiscal quarter to which this report relates that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

PART II

OTHER INFORMATION

Item 1.Legal Proceedings

In addition to the following matter, we are involved in various claims and legal actions arising in the ordinary course of business, including employee injury claims. After conferring with counsel, it is the opinion of management that the ultimate resolution of these claims, to the extent not previously provided for, will not have a material adverse effect on our consolidated financial condition, results of operations or liquidity.

FTC Temporary Restraining Order and Preliminary Injunction Blocking Joint Venture with Peabody

On June 18, 2019, Arch Resources entered into the Implementation Agreement with Peabody to establish a joint venture that would have combined the companies’ respective Powder River Basin and Colorado mining operations.

Formation of the joint venture was subject to customary closing conditions, including the termination or expiration of the waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, the receipt of certain other required regulatory approvals and the absence of injunctions or other legal restraints preventing the formation of the joint venture. Formation of the joint venture did not require approval of our stockholders or Peabody’s stockholders.

On February 26, 2020, the Federal Trade Commission (“FTC”) filed an administrative complaint challenging the proposed joint venture alleging that the transaction would have eliminated competition between us and Peabody, the two major competitors in the market for thermal coal in the Southern Powder River Basin and the two largest coal-mining companies in the United States. On February 26, 2020, the FTC filed for a temporary restraining order and preliminary injunction in the U.S. District Court for the Eastern District of Missouri, to maintain the status quo pending an administrative trial on the merits.

Between July 14 and July 23, 2020, the U.S. District Court conducted an evidentiary hearing, during which both sides further presented their evidence and arguments. On September 29, 2020, the U.S. District Court upheld the FTC’s decision to block the joint venture. Subsequently, the Company and Peabody jointly terminated the joint venture.

Item 1A. Risk Factors

The COVID-19 pandemic has adversely affected, and will continue to adversely affect, our business, financial condition, liquidity and results of operations.

The coronavirus disease 2019 (“COVID-19”) pandemic has resulted in a widespread health crisis that has adversely affected businesses, economies and financial markets worldwide. The full impact of COVID-19 is unknown and rapidly evolving. Our business, financial condition, liquidity and results of operations have been, and will continue to be, adversely affected by the COVID-19 pandemic. Our profitability and the value of our coal reserves depend upon the prices we receive for our coal, which are largely dependent on prevailing market prices. Measures taken to address and limit the spread of the disease—such as stay-at-home orders, social distancing guidelines, and travel restrictions—have adversely affected the economies and financial markets of many countries, resulting in an economic downturn that has in turn negatively impacted, and may continue to negatively impact, global demand and prices for coal, as well as a widespread increase in unemployment that is expected to further reduce demand and prices for coal. These conditions may lead to extreme volatility of coal prices, severely limited liquidity and credit availability and declining valuations of assets, which may adversely affect our business, financial condition, liquidity and results of operations.

In addition, the COVID-19 pandemic, and measures taken by governments, organizations, the Company and its customers to reduce its effects could potentially impact the Company’s employees, customers and suppliers. Such disruptions may continue or increase in the future, and could adversely affect, our business, financial condition, liquidity and results of operations. 

The COVID-19 pandemic may also have the effect of heightening many of the other risks described in Item 1A, “Risk Factors” of our annual report on Form 10-K for the year ended December 31, 2019, including, but not limited to, those relating to: coal prices; economic and market conditions; decreases in coal consumption; our ability to fund necessary capital expenditures; disruptions in the availability of mining and other industrial supplies; changes in purchasing patterns of our customers and their effects on our coal supply agreements; our reliance on key managers and employees; and our ability to access the capital markets and obtain financing and insurance upon favorable terms; among others. 

The full extent to which the COVID-19 pandemic will impact our results is unknown and evolving, and will depend on future developments, which are highly uncertain and cannot be predicted. These include the severity, duration and spread of COVID-19, the success of actions taken by governments and health organizations to combat the disease and treat its effects, including additional remedial legislation, and the extent to which, and when, general economic and operating conditions recover. Accordingly, any resulting financial impact cannot be reasonably estimated at this time but such amounts may be material.

Item 2.Unregistered Sales of Equity Securities and Use of Proceeds

On April 17, 2019, the Board of Directors authorized an additional $300 million to the share repurchase program, bringing the total authorization since the program’s launch to $1.05 billion. The timing of any future share purchases, and the ultimate number of shares to be purchased, will depend on a number of factors, including business and market conditions, our future financial performance, and other capital priorities. The shares will be acquired in the open market or through private transactions in accordance with Securities and Exchange Commission requirements. The share repurchase program has no termination date, but may be amended, suspended or discontinued at any time and does not commit us to repurchase shares of our common stock. The actual number and value of the shares to be purchased will depend on the performance of our stock price and other market conditions. We did not purchase any shares of our common stock under this program for the quarter ended September 30, 2020.

As of September 30, 2020, we had approximately $223 million remaining authorized for stock repurchases under this program.

WAIVER LETTER AGREEMENT AND

SECOND AMENDMENT TO CREDIT AGREEMENT

June 17, 2020

VIA EMAIL

Arch Resources, Inc., as Borrower Agent

One CityPlace Drive, Suite 300

St. Louis, MO 63141

Attention: Robert G. Jones

Re:Waiver of Designated Defaults and Second Amendment to Credit Agreement

Ladies and Gentlemen:

Reference is made to that certain Credit Agreement dated April 27, 2017 (as at any time amended, restated, modified or supplemented, the "Credit Agreement"), among ARCH RESOURCES, INC., a Delaware corporation formerly known as Arch Coal, Inc. ("Arch"), the various direct and indirect subsidiaries of Arch identified on the signature pages thereto as "Borrowers" (together with Arch, collectively, "Borrowers", and each individually a "Borrower"), REGIONS BANK, as agent (in its capacity as agent, the "Administrative Agent") for certain financial institutions (collectively, the “Lenders”), and the Lenders.  Capitalized terms used herein and not otherwise defined herein shall have the meanings ascribed to such terms in the Credit Agreement.

Borrowers have advised Administrative Agent that Borrowers caused the legal name of Simba Group LLC (the “Subject Subsidiary”), a subsidiary of Arch and a Borrower, to be changed to Maidsville Landing Terminal, LLC pursuant to a Certificate of Amendment to Certificate of Formation of Simba Group LLC filed with the Delaware Secretary of State on March 5, 2020 (such name change, the “Name Change”).  As you know, Events of Default (collectively, the “Designated Events of Default") resulted from (a) Borrowers’ failure to give Administrative Agent prior written notice of the Name Change as required by Section 10.13(b) of the Credit Agreement and in violation of Section 12.1(c) of the Credit Agreement, and (b) Borrowers’ failure to give similar notices to Term Loan Agent and PNC Bank, National Association, in its capacity as administrator under the Receivables Purchase Agreement (the “Receivables Administrator”), as required by the Term Loan Agreement and the Receivables Purchase Agreement, respectively, in each case resulting in a default thereunder and a violation of Section 12.1(e)(i) of the Credit Agreement.  Borrowers have advised Administrative Agent that, as of the date hereof, all actions with respect to the Name Change have been taken in order to maintain a perfected Lien in favor of each of the Administrative Agent, the Term Loan Agent and the Receivables Administrator, with the priority as described in the Loan Documents, in the assets of the Subject Subsidiary that constitute Collateral.  

In addition, Borrowers have advised Administrative Agent that certain Deposit Accounts, Securities Accounts and/or Commodities Accounts that do not constitute Excluded Accounts (each, a “Subject Account”) have been formed but are not currently subject to Control Agreements.  The Borrowers are in the process of causing the applicable securities intermediaries or other applicable Persons to enter into Control Agreements

6510038.v6

with respect to the Subject Accounts as required by the Security Agreement (such actions, the “After Acquired Collateral Actions” and any Defaults that have arisen with respect to the failure to take the After Acquired Collateral Actions within the specified time periods in the Security Agreement are referred to herein as the “After Acquired Collateral Defaults”; the After Acquired Collateral Defaults, together with the Designated Events of Default, are referred to herein as the “Designated Defaults”).  

The Administrative Agent and Required Lenders have agreed to waive the Designated Defaults on the terms and subject to the conditions of this letter agreement (this “Agreement”).

NOW, THEREFORE, for TEN DOLLARS ($10.00) in hand paid and other good and valuable consideration, the receipt and sufficiency of which are hereby severally acknowledged, the parties hereto, intending to be legally bound hereby, agree as follows:

2.Amendment to Credit Agreement.  The Credit Agreement is hereby amended by deleting Section 12.1(c) thereof in its entirety and by substituting in lieu thereof the following:

(c)Breach of Negative Covenants or Certain Other Covenants.  Any of the Loan Parties shall default in the observance or performance of (i) the covenant contained in Section 10.13(b) and such default, solely to the extent capable of cure, shall continue unremedied for a period of thirty (30) days or (ii) any covenant contained in Section 9.1, 9.3 (with respect to the ABL Priority Collateral), 9.5, 9.15, 9.16(f)(i), 9.16(f)(ii), 9.18, Section 10 (other than Section 10.13(b)), or Section 11.

3.Ratification and Reaffirmation.  Each Loan Party hereby ratifies and reaffirms the Obligations, each of the Loan Documents to which it is a party, and all of such Loan Party’s covenants, duties, indebtedness and liabilities under the Loan Documents to which it is a party.

4.Waiver Fee; Expenses.  To induce Administrative Agent and Required Lenders to enter into this Agreement, Borrowers jointly and severally agree to pay to Administrative Agent, for the benefit of each of the consenting Lenders, on the date hereof a fully earned and non-refundable waiver fee in the amount of 0.05% of the aggregate principal amount of the Commitments of the consenting Lenders in immediately available funds (the “Waiver Fee”).  Additionally, Borrowers jointly and severally agree to pay all out-of-pocket expenses incurred by the Administrative Agent in connection with the preparation, negotiation, execution, delivery and enforcement of this Amendment  and the other documents and instruments referred to herein or contemplated hereby, including, but not limited to, the fees and disbursements of Administrative Agent’s legal counsel, in each case, to the extent provided in the Credit Agreement.

5.Acknowledgments and Stipulations.  Each Loan Party acknowledges and stipulates that this Agreement and each other Loan Document to which such Loan Party is party constitutes a legal, valid and binding obligation of such Loan Party that is enforceable against such Loan Party in accordance with the terms

2

hereof or thereof, as applicable, except to the extent that enforceability of any portion hereof or thereof may be limited by bankruptcy, insolvency, reorganization, moratorium or other similar laws affecting the enforceability of creditors’ rights generally or limiting the right of specific performance; that all of the Obligations are owing and payable, in each case to the extent provided in the Loan Documents, without defense, offset or counterclaim (and to the extent there exists any such defense, offset or counterclaim on the date hereof, the same is hereby knowingly and voluntarily waived by each Loan Party); and that the security interests and Liens granted by such Loan Party in favor of Administrative Agent are fully perfected first priority security interests and Liens (subject only to Permitted Liens) in and to the assets of the Loan Parties that constitute ABL Priority Collateral and second priority Liens (subject only to Permitted Liens) in and to the assets of the Loan Parties that constitute Term Loan Priority Collateral (in each case, subject to any remaining actions that may be required in accordance with Section 9.20 of the Credit Agreement).

6.Representations and Warranties.  Each Loan Party represents and warrants to Administrative Agent and Required Lenders, to induce each to enter into this Agreement, that no Default or Event of Default (other than the Designated Defaults) exists on the date hereof; that the execution, delivery and performance of this Agreement have been duly authorized by all requisite corporate or company action on the part of such Loan Party and this Agreement has been duly executed and delivered by such Loan Party; and that all of the representations and warranties made by such Loan Party in the Credit Agreement are true and correct in all material respects on the effective date hereof (provided that any representation or warranty that is qualified as to “materiality,” “Material Adverse Change” or similar language shall be true and correct (after giving effect to such qualification) in all respects on such effective date), except for those representations and warranties that expressly relate to an earlier date, in which case, they shall have been true and correct in all material respects as of such earlier date.

7.No Novation, etc.  Except as otherwise expressly provided in this Agreement, nothing herein shall be deemed to amend or modify any provision of the Credit Agreement or any of the other Loan Documents, each of which shall remain in full force and effect.  This Agreement is not intended to be, nor shall it be construed to create, a novation or accord and satisfaction, and the Credit Agreement as herein modified shall continue in full force and effect.  Upon the effectiveness of this Agreement, each reference in the Credit Agreement to "this Agreement," "hereunder," or words of like import shall mean and be a reference to the Credit Agreement, as amended by this Amendment.

8.Release of Claims.  In consideration of Administrative Agent’s and Required Lenders’ agreement to waive the Designated Defaults, each Loan Party hereby RELEASES, ACQUITS AND FOREVER DISCHARGES Administrative Agent, each LC Issuer and each Lender, and each of their respective officers, directors, agents, employees, representatives, Affiliates and trustees and any successors and assigns of any of the foregoing (each, a "Releasee", and collectively, the "Releasees"), from any and all liabilities, claims, demands, actions or causes of action of any kind or nature (if there be any), whether absolute or contingent, disputed or undisputed, at law or in equity, or known or unknown, that any Loan Party now has or ever had against any of the Releasees arising under or in connection with the Loan Documents, based in whole or in part on facts, whether or not now known, existing on or before the date of this Agreement (collectively, “Claims”).  Each Loan Party hereby represents and warrants to the Releasees that no Loan Party has transferred or assigned to any person or entity of any kind any Claim that such Loan Party ever had or claimed to have against any Releasee.

9.Miscellaneous.  The waiver and amendment contained herein shall not be effective until Administrative Agent shall have received (i) a counterpart hereof duly executed by Borrower Agent, on behalf of the Loan Parties, at which time this Agreement shall constitute an agreement among the parties hereto with respect to the agreements contained herein, (ii) evidence reasonably satisfactory to the Administrative Agent that waivers by the requisite consenting parties have been obtained with respect to any events of default or termination events existing under the Term Loan Agreement and the Receivables Purchase Agreement as a result of the Name Change, and (iii) the Waiver Fee.  THIS AGREEMENT SHALL BE GOVERNED BY

(aa)By deleting Section 15.1(a) of the Credit Agreement in its entirety and by substituting in lieu thereof the following:

10

(bb)By deleting Section 15.1(h) of the Credit Agreement in its entirety and by substituting in lieu thereof the following:

(h)Benchmark Transition Event.  Notwithstanding anything to the contrary contained in this Agreement or any other Loan Document, but without limiting subsections (b) of this Section 15.1, upon the occurrence of a Benchmark Transition Event or an Early Opt-in Election, as applicable, and its related Benchmark Transition Event, Administrative Agent and the Borrower Agent may amend this Agreement to replace LIBOR with a Benchmark Replacement.  Any such amendment with respect to a Benchmark Transition Event will become effective at 5:00 p.m. on the fifth (5th) Business Day after Administrative Agent has posted such proposed amendment to all Lenders, so long as Administrative Agent has not received, by such time, written notice of objection to such amendment from Lenders comprising at such time the Required Lenders.  Any such amendment with respect to an Early Opt-in Election will become effective on the date that Lenders comprising the Required Lenders have delivered written notice to Administrative Agent that such Required Lenders accept such amendment. No replacement of LIBOR with a Benchmark Replacement pursuant hereto will occur prior to the applicable Benchmark Replacement Date. In connection with the implementation of a Benchmark Replacement, Administrative Agent will have the right to make Benchmark Replacement Conforming Changes from time to time and, notwithstanding anything to the contrary herein or in any other Loan Document, any amendments to any Loan Documents implementing such Benchmark Replacement Conforming Changes will become effective without any further action or consent of any other party to this Agreement. Administrative Agent will promptly notify the Borrower Agent and the Lenders of (i) any occurrence of a Benchmark Transition Event or an Early Opt-in Election, as applicable, and its related Benchmark Replacement Date, (ii) the implementation of any Benchmark Replacement, (iii) the effectiveness of any Benchmark Replacement Conforming Changes, and (iv) the commencement or conclusion of any Benchmark Unavailability Period. Any determination, decision or election that may be made by Administrative Agent or Lenders pursuant to this Section,  including any determination with respect to a tenor, rate or adjustment or of the occurrence or non-occurrence of an event, circumstance or date and any decision to take or refrain from taking any action, will be conclusive and binding absent manifest error on all parties and may be made in its or their sole discretion and without consent from any other party hereto, except, in each case, as expressly may be  required pursuant to this Section. Upon the Borrower

11

Agent’s receipt of notice of the commencement of a Benchmark Unavailability Period, the Borrower Agent may revoke any request for a Borrowing of a LIBOR Rate Loan or, conversion to or continuation of a LIBOR Rate Loan to be made, converted or continued during any Benchmark Unavailability Period, provided, that, in the event that the Borrower Agent does not revoke such request or does not revoke such request in the time or manner required herein, then, any such request shall be deemed to be a request for a Borrowing of, or conversion to, a Base Rate Loan.  During any Benchmark Unavailability Period, any component of the Base Rate based upon LIBOR will not be used in any determination of the Base Rate.

(cc)By deleting each reference to “Arch Coal, Inc.” in the Credit Agreement and the other Loan Documents and by substituting in lieu thereof, in each case, a reference to “Arch Resources, Inc., formerly known as Arch Coal, Inc.”

(dd)By deleting Exhibit E to the Credit Agreement in its entirety and by substituting in lieu thereof the replacement exhibit attached hereto as Annex A.

5.Representations and Warranties.  Each Borrower represents and warrants to Administrative Agent and the Lenders, to induce each to enter into this Amendment, that no Default or Event of Default exists on the date hereof; that the execution, delivery and performance of this Amendment have been duly authorized by all requisite corporate or company action on the part of such Borrower and this Amendment has been duly executed and delivered by such Borrower; and that all of the representations and warranties made by such Borrower in the Credit Agreement are true and correct in all material respects on the effective date hereof (provided that any representation or warranty that is qualified as to “materiality,” “Material Adverse Change” or similar language shall be true and correct (after giving effect to such qualification) in all respects on such effective date), except for those representations and warranties

8.Conditions Precedent.  The effectiveness of the amendments contained in Section 2 hereof is subject to the satisfaction of each of the following conditions precedent, in form and substance satisfactory to Administrative Agent, unless satisfaction thereof is specifically waived in writing by Administrative Agent:

10.Governing Law.  THIS AMENDMENT SHALL BE GOVERNED BY THE LAWS OF THE STATE OF NEW YORK, WITHOUT GIVING EFFECT TO ANY CONFLICT OF LAW PRINCIPLES OR OTHER RULE OF LAW WHICH WOULD CAUSE THE APPLICATION OF THE LAW OF ANY JURISDICTION OTHER THAN THE LAW OF THE STATE OF NEW YORK.

13.Entire Agreement.  This Amendment constitutes the entire understanding among the parties hereto with respect to the subject matter hereof and supersedes any prior agreements, written or oral, with respect thereto.  THIS WRITTEN AGREEMENT REPRESENTS THE FINAL AGREEMENT AMONG THE PARTIES AND MAY NOT BE CONTRADICTED BY EVIDENCE OF PRIOR, CONTEMPORANEOUS, OR SUBSEQUENT ORAL AGREEMENTS OF THE PARTIES.  THERE ARE NO UNWRITTEN ORAL AGREEMENTS AMONG THE PARTIES.

14.Miscellaneous.  This Amendment may be executed in any number of counterparts and by different parties to this Amendment on separate counterparts, each of which, when so executed, shall be deemed an original, but all such counterparts shall constitute one and the same agreement.  Any manually executed signature page to this Amendment delivered by a party by facsimile or other electronic transmission shall be deemed to be an original signature hereto.  Section titles and references used in this Amendment shall be without substantive meaning or content of any kind whatsoever and are not a part of the agreements among the parties hereto.

Mine Safety and Health Administration Safety Data

We believe that Arch Resources, Inc. (“Arch Resources”) is one of the safest coal mining companies in the world.  Safety is a core value at Arch Resources and at our subsidiary operations.  We have in place a comprehensive safety program that includes extensive health & safety training for all employees, site inspections, emergency response preparedness, crisis communications training, incident investigation, regulatory compliance training and process auditing, as well as an open dialogue between all levels of employees.  The goals of our processes are to eliminate exposure to hazards in the workplace, ensure that we comply with all mine safety regulations, and support regulatory and industry efforts to improve the health and safety of our employees along with the industry as a whole.

The operation of our mines is subject to regulation by the Federal Mine Safety and Health Administration (MSHA) under the Federal Mine Safety and Health Act of 1977 (Mine Act).  MSHA inspects our mines on a regular basis and issues various citations, orders and violations when it believes a violation has occurred under the Mine Act.  We present information below regarding certain mining safety and health violations, orders and citations, issued by MSHA and related assessments and legal actions and mine-related fatalities with respect to our coal mining operations.  In evaluating the above information regarding mine safety and health, investors should take into account factors such as: (i) the number of citations and orders will vary depending on the size of a coal mine, (ii) the number of citations issued will vary from inspector to inspector and mine to mine, and (iii) citations and orders can be contested and appealed, and in that process are often reduced in severity and amount, and are sometimes dismissed or vacated.

The table below sets forth for the three months ended September 30, 2020 for each active MSHA identification number of Arch Resources and its subsidiaries, the total number of: (i) violations of mandatory health or safety standards that could significantly and substantially contribute to the cause and effect of a coal or other mine safety or health hazard under section 104 of the Mine Act for which the operator received a citation from MSHA; (ii) orders issued under section 104(b) of the Mine Act; (iii) citations and orders for unwarrantable failure of the mine operator to comply with mandatory health or safety standards under section 104(d) of the Mine Act; (iv) flagrant violations under section 110(b)(2) of the Mine Act; (v) imminent danger orders issued under section 107(a) of the Mine Act; (vi) proposed assessments from MHSA (regardless of whether Arch Coal has challenged or appealed the assessment); (vii) mining-related fatalities; (viii) notices from MSHA of a pattern of violations of mandatory health or safety standards that are of such nature as could have significantly and substantially contributed to the cause and effect of coal or other mine health or safety hazards under section 104(e) of the Mine Act; (ix) notices from MSHA regarding the potential to have a pattern of violations as referenced in (viii) above; and (x) pending legal actions before the Federal Mine Safety and Health Review Commission (as of September 30, 2020) involving such coal or other mine, as well as the aggregate number of legal actions instituted and the aggregate number of legal actions resolved during the reporting period.

Recently Adopted Accounting Guidance

In June 2016, the FASB issued ASU 2016-13, “Financial Instruments-Credit Losses (Topic 326), Measurement of Credit Losses on Financial Instruments,” and also issued subsequent amendments to the initial guidance under ASU 2018-19, ASU 2019-04 and ASU 2019-05. The standard modifies the measurement approach for credit losses on financial instruments, including trade receivables, from an incurred loss method to a current expected credit loss method, otherwise known as “CECL.” The standard requires the measurement of expected credit losses to be based on relevant information, including historical experience, current conditions and a forecast that is supportable. The Company adopted the standard in the first quarter of 2020, with minimal impact to the Company’s financial results.

As part of the adoption, the Company reviewed its portfolio of available-for-sale debt securities in an unrealized loss position, and assessed whether it intends to sell, or it is more likely than not that it will be required to sell before recovery of its amortized cost basis. The Company determined that it currently does not intend to sell these securities before recovery of their amortized cost basis. Additionally, the Company evaluated whether the decline in fair value has resulted from credit losses or other factors by considering the extent to which the fair value is less than amortized cost, any changes to the rating of the security by a rating agency, and adverse conditions specifically related to the security, among other factors. If this assessment indicates that a credit loss exists, the Company compares the present value of the cash flows expected to be collected against the amortized cost basis. A credit loss is recorded if the present value of the cash flows is less than the amortized cost basis, limited by the amount that the fair value is less than the amortized cost basis. Upon adoption, the Company did not record an allowance for credit losses on its available-for-sale debt securities.

Additionally, the Company reviewed its open trade receivables arising from contractual coal sales. As part of its analysis, the Company performs periodic credit reviews of all active customers, reviews all trade receivables greater than 90 days past due, calculates historical loss rates and reviews current payment trends of all customers.

Recent Accounting Guidance Issued Not Yet Effective

In December 2019, the FASB issued ASU 2019-12, “Income Taxes (Topic 740) Simplifying the Accounting for Income Taxes.” ASU 2019-12 eliminates certain exceptions related to the approach for intraperiod tax allocation, the methodology for calculating income taxes in an interim period and the recognition of deferred tax liabilities for outside basis differences. The ASU is effective for public companies for fiscal years beginning after December 15, 2020, and interim periods therein with early adoption permitted. The Company is reviewing the provisions of the standard but does not expect a significant impact to the Company's financial statements.

In March 2020, the FASB issued ASU 2020-04, "Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting." The amendments provide optional guidance for a limited time to ease the potential burden in accounting for reference rate reform. The new guidance provides optional expedients and exceptions for applying U.S. GAAP to contracts, hedging relationships and other transactions affected by reference rate reform if certain criteria are met. The amendments apply only to contracts and hedging relationships that reference LIBOR or another reference rate expected to be discontinued due to reference rate reform. These amendments are effective immediately and may be applied prospectively to contract modifications made and hedging relationships entered into or evaluated on or before December 31, 2022. We are currently evaluating our contracts and the optional expedients provided by the new standard.

Joint Venture with Peabody Energy

3. Joint Venture with Peabody Energy

On June 18, 2019, Arch Coal, Inc. (now Arch Resources) entered into a definitive implementation agreement (the “Implementation Agreement”) with Peabody Energy Corporation (“Peabody”), to establish a joint venture that would have combined the respective Powder River Basin and Colorado mining operations of Arch Resources and Peabody. Pursuant to the terms of the Implementation Agreement, Arch Resources would have held a 33.5% economic interest, and Peabody would have held a 66.5% economic interest in the joint venture.

On February 26, 2020, the Federal Trade Commission (“FTC”) filed an administrative complaint challenging the proposed joint venture alleging the transaction will eliminate competition between Arch Resources and Peabody, the two major competitors in the market for thermal coal in the Southern Powder River Basin and the two largest coal-mining companies in the United States. The FTC filed a temporary restraining order and preliminary injunction in the U.S. District Court for the Eastern District of Missouri, to maintain the status quo pending an administrative trial on the merits.

Between July 14 and July 23, 2020, the U.S. District Court conducted an evidentiary hearing, during which both sides further presented their evidence and arguments. On September 29, 2020, the U.S. District Court upheld the FTC’s decision to block the joint venture. Subsequently, the Company and Peabody jointly terminated the joint venture.

The Company has incurred expenses of $4.4 million and $15.9 million for the three and nine months ended September 30, 2020, respectively, associated with the regulatory approval process related to the joint venture. Costs of $3.8 million and $6.8 million were incurred for the three and nine months ended September 30, 2019, respectively.

The Company recorded a $39 million gain during the third quarter of 2019 related to a settlement with the United States Department of Interior over a long-standing dispute, dating back to the 1970’s, on the valuation and disposition of Preference Rights Lease Applications that Arch controlled in northwestern New Mexico with a joint venture partner. As part of the settlement, Arch received $67.0 million in the form of royalty credits on its federal coal leases which will be used to settle 50% of the Company’s monthly royalty obligations. The Company expects to realize the royalty credits beginning in September 2019 through the next 18-24 months depending on market conditions. Additionally, as part of the settlement, the Company made a one-time payment of $27.0 million during October 2019 to its’ partner in the venture for its ownership interest in the underlying mineral reserves, as well as paid $1.0 million in closing fees.

As of September 30, 2020, the Company realized $8.7 million and $25.8 million towards its royalty obligations for the three months and nine months ended September 30, 2020. The Company realized a credit of $5 million towards its royalty obligations during the quarter ended September 30, 2019. The remaining receivable balance outstanding at September 30, 2020 is $27.8 million which is expected to be received over the next three quarters.

8. Asset Impairment

The following table summarizes the amounts reflected on the line “Asset impairment” in the Condensed Consolidated Statements of Operations:

	September 30,
Description	2020
	(In thousands)
Coal lands and mineral rights	$	33,197
Plant and equipment		43,197
Deferred development		50,527
Equity Investment		36,167
	$	163,088

The Company’s thermal coal segments have experienced reduced demand as a result of sustained low natural gas pricing, reduced utilization and retirement of coal-fired power plants, the increased use of renewable energy sources, and the impact of COVID-19. The reduced demand has led to lower production levels, higher unit costs, and lower realized prices, which have contributed to operating losses at certain of the mine complexes. Further, on September 29, 2020 the U.S. District Court upheld the FTC’s decision to block the Company’s proposed joint venture. These conditions have resulted in changes to the Company’s expectations for projected future volume levels and the overall longevity of the mines. During the third quarter of 2020, the Company determined that these conditions represented indicators of impairment with respect to certain of its long-lived assets or asset groups. As a result, the Company recorded impairment charges during the three and nine months ended September 30, 2020 of $51.8 million related to the Coal Creek Mine within the Powder River Basin Mining segment, $33.5 million related to the Viper Mine within the Other Thermal Segment, $41.6 million related to the West Elk Mine within the Other Thermal segment and $36.2 million related to the Company’s equity method investment in Knight Hawk Holdings, LLC. The impairment charges were based upon

estimated discounted cash flows that were based on estimates of future sales volumes, coal prices for unpriced volumes, production costs and a risk-adjusted cost of capital. These estimates generally constitute unobservable Level 3 inputs under the fair value hierarchy.

11. Investments in Available-for-Sale Securities

The Company has invested in marketable debt securities, primarily highly liquid U.S. Treasury securities and investment grade corporate bonds. These investments are held in the custody of a major financial institution. These securities are classified as available-for-sale securities and, accordingly, the unrealized gains and losses are recorded through other comprehensive income.

The Company’s investments in available-for-sale marketable securities are as follows:

	September 30, 2020

Total Investments	$	135,687	$	201	$	(221)	$	—	$	135,667

The aggregate fair value of investments with unrealized losses that were owned for less than a year was $48.5 million and $72.3 million at September 30, 2020 and December 31, 2019, respectively. The aggregate fair value of investments with unrealized losses that were owned for over a year was $9.6 million and $0.0 million at September 30, 2020 and December 31, 2019, respectively. The unrealized losses in the Company’s portfolio at September 30, 2020 are the result of normal market fluctuations. The Company does not currently intend to sell these investments before recovery of their amortized cost base.

The debt securities outstanding at September 30, 2020 have maturity dates ranging from the fourth quarter of 2020 through the first quarter of 2022. The Company classifies its investments as current based on the nature of the investments and their availability to provide cash for use in current operations.

12. Derivatives

Interest rate risk management

The Company has entered into interest rate swaps to reduce the variability of cash outflows associated with interest payments on its variable rate term loan. These swaps have been designated as cash flow hedges. For additional information on these arrangements, see Note 14, “Debt and Financing Arrangements,” in the Condensed Consolidated Financial Statements.

Diesel fuel price risk management

The Company is exposed to price risk with respect to diesel fuel purchased for use in its operations. The Company anticipates purchasing approximately 30 to 35 million gallons of diesel fuel for use in its operations annually. To protect the Company’s cash flows from increases in the price of diesel fuel for its operations, the Company uses forward physical diesel purchase contracts, purchased heating oil call options and New York Mercantile Exchange (“NYMEX”) gulf coast diesel swaps and options. At September 30, 2020, the Company had protected the price on the majority of its expected diesel fuel purchases for the remainder of 2020 with approximately 2 million gallons of heating oil call options with an average strike price of $1.76 per gallon and 2.0 million gallons of NYMEX gulf coast diesel swaps at an average price of approximately $1.05 per gallon. These positions are not designated as hedges for accounting purposes, and therefore, changes in the fair value are recorded immediately to earnings.

Coal price risk management positions

The Company may sell or purchase forward contracts, swaps and options in the over-the-counter coal market in order to manage its exposure to coal prices. The Company has exposure to the risk of fluctuating coal prices related to forecasted, index-priced sales or purchases of coal or to the risk of changes in the fair value of a fixed price physical sales contract. Certain derivative contracts may be designated as hedges of these risks.

At September 30, 2020, the Company held derivatives for risk management purposes that are expected to settle in the following years:

(Tons in thousands)	2020	2021	Total
Coal sales	255	33	288
Coal purchases	238	—	238

The Company has also entered into a minimal quantity of natural gas put options to protect the Company from decreases in natural gas prices, which could impact thermal coal demand. These options are not designated as hedges.

Coal trading positions

The Company may sell or purchase forward contracts, swaps and options in the over-the-counter coal market for trading purposes. The Company is exposed to the risk of changes in coal prices on the value of its coal trading portfolio. The estimated future realization of the value of the trading portfolio is $0.2 million of losses during the remainder of 2020 and $0.3 million of gains during 2021.

Tabular derivatives disclosures

The Company has master netting agreements with all of its counterparties which allow for the settlement of contracts in an asset position with contracts in a liability position in the event of default or termination. Such netting arrangements reduce the Company’s credit exposure related to these counterparties. For classification purposes, the Company records the net fair value of all the positions with a given counterparty as a net asset or liability in the Condensed Consolidated Balance Sheets. The amounts shown in the table below represent the fair value position of individual contracts, and not the net position presented in the accompanying Condensed Consolidated Balance Sheets.

Term Loan Facility

In 2017, the Company entered into a senior secured term loan credit agreement (the “Credit Agreement”) in an aggregate principal amount of $300 million (the “Term Loan Debt Facility”) with Credit Suisse AG, Cayman Islands Branch, as administrative agent and collateral agent, and the other financial institutions from time to time party thereto (collectively, the “Lenders”). The Term Loan Debt Facility was issued at 99.50% of the face amount and will mature on March 7, 2024. The term loans provided under the Term Loan Debt Facility (the “Term Loans”) are subject to quarterly principal amortization payments in an amount equal to $750,000.

During 2018, the Company entered into the Second Amendment (the “Second Amendment”) to its Credit Agreement. The Second Amendment reduced the interest rate on its Term Loan Debt Facility to, at the option of Arch Resources, either (i) the London interbank offered rate (“LIBOR”) plus an applicable margin of 2.75%, subject to a 1.00% LIBOR floor, or (ii) a base rate plus an applicable margin of 1.75%. The LIBOR floor remains at 1.00%. There is no change to the maturities as a result of the Second Amendment.

The Term Loan Debt Facility is guaranteed by all existing and future wholly owned domestic subsidiaries of the Company (collectively, the “Subsidiary Guarantors” and, together with Arch Resources, the “Loan Parties”), subject to customary exceptions, and is secured by first priority security interests on substantially all assets of the Loan Parties, including 100% of the voting equity interests of directly owned domestic subsidiaries and 65% of the voting equity interests of directly owned foreign subsidiaries, subject to customary exceptions.

The Company has the right to prepay the Term Loan at any time, and from time to time, in whole or in part without premium or penalty, upon written notice, except that any prepayment of the Term Loan that bear interest at the LIBOR Rate other than at the end of the applicable interest periods therefore shall be made with reimbursement for any funding losses and redeployment costs of the Lenders resulting therefrom.

The Term Loan Debt Facility is subject to certain usual and customary mandatory prepayment events, including 100% of net cash proceeds of (i) debt issuances (other than debt permitted to be incurred under the terms of the Term Loan Debt Facility) and (ii) non-ordinary course asset sales or dispositions, subject to customary thresholds, exceptions and reinvestment rights.

The Term Loan Debt Facility contains customary affirmative covenants and representations.

The Term Loan Debt Facility also contains customary negative covenants, which, among other things, and subject to certain exceptions, include restrictions on (i) indebtedness, (ii) liens, (iii) liquidations, mergers, consolidations and acquisitions, (iv) disposition of assets or subsidiaries, (v) affiliate transactions, (vi) creation or ownership of certain subsidiaries, partnerships and joint ventures, (vii) continuation of or change in business, (viii) restricted payments, (ix) prepayment of subordinated and junior lien indebtedness, (x) restrictions in agreements on dividends, intercompany loans and granting liens on the collateral, (xi) loans and investments, (xii) sale and leaseback transactions, (xiii) changes in organizational documents and fiscal year and (xiv) transactions with respect to bonding subsidiaries. The Term Loan Debt Facility does not contain any financial maintenance covenants.

The Term Loan Debt Facility contains customary events of default, subject to customary thresholds and exceptions, including, among other things, (i) nonpayment of principal and nonpayment of interest and fees, (ii) a material inaccuracy of a representation or warranty at the time made, (iii) a failure to comply with any covenant, subject to customary grace periods in the case of certain affirmative covenants, (iv) cross-events of default to indebtedness of at least $50 million, (v) cross-events of default to surety, reclamation or similar bonds securing obligations with an aggregate face amount of at least $50 million, (vi) uninsured judgments in excess of $50 million, (vii) any loan document shall cease to be a legal, valid and binding agreement, (viii) uninsured losses or proceedings against assets with a value in excess of $50 million, (ix) certain ERISA events, (x) a change of control or (xi) bankruptcy or insolvency proceedings relating to the Company or any material subsidiary of the Company.

Accounts Receivable Securitization Facility

On September 30, 2020, the Company amended and extended its existing trade accounts receivable securitization facility provided to Arch Receivable Company, LLC, a special-purpose entity that is a wholly owned subsidiary of Arch Resources (“Arch Receivable”) (the “Extended Securitization Facility”), which supports the issuance of letters of credit and requests for cash advances. The amendment to the Extended Securitization Facility reduces the size of the facility from $160 million to $110 million of borrowing capacity and extended the maturity date to September 29, 2023. Additionally, the amendment eliminated the provision that accelerated maturity upon liquidity falling below a specified level. Pursuant to the Extended Securitization Facility, Arch Receivable also agreed to a revised schedule of fees payable to the administrator and the providers of the Extended Securitization Facility.

Under the Extended Securitization Facility, Arch Receivable, Arch Resources and certain of Arch Resources’s subsidiaries party to the Extended Securitization Facility have granted to the administrator of the Extended Securitization Facility a first priority security interest in eligible trade accounts receivable generated by such parties from the sale of coal and all proceeds thereof. As of September 30, 2020, letters of credit totaling $50.0 million were outstanding under the facility with $34.5 million available for borrowings.

Inventory-Based Revolving Credit Facility

On September 30, 2020, the Company and certain of its subsidiaries amended the senior secured inventory-based revolving credit facility in an aggregate principal amount of $50 million (the “Inventory Facility”) with Regions Bank (“Regions”) as administrative agent and collateral agent, as lender and swingline lender (in such capacities, the “Lender”) and as letter of credit issuer. Availability under the Inventory Facility is subject to a borrowing base consisting of (i) 85% of the net orderly liquidation value of eligible coal inventory, (ii) the lesser of (x) 85% of the net orderly

liquidation value of eligible parts and supplies inventory and (y) 35% of the amount determined pursuant to clause (i), and (iii) 100% of Arch Resources’s Eligible Cash (defined in the Inventory Facility), subject to reduction for reserves imposed by Regions.

The amendment of the Inventory Facility extended the maturity of the facility to September 29, 2023; eliminated the provision that accelerated maturity upon liquidity falling below a specified level; and reduced the minimum liquidity requirement from $175 million to $100 million. Additionally, the amendment includes provisions that reduce the advance rates for coal inventory and parts and supplies, depending on Liquidity.

Revolving loan borrowings under the Inventory Facility bear interest at a per annum rate equal to, at the option of Arch Resources, either the base rate or the London interbank offered rate plus, in each case, a margin ranging from 2.50% to 3.50% (in the case of LIBOR loans) and 1.00% to 1.50% (in the case of base rate loans) determined using a Liquidity-based grid. Letters of credit under the Inventory Facility are subject to a fee in an amount equal to the applicable margin for LIBOR loans, plus customary fronting and issuance fees.

All existing and future direct and indirect domestic subsidiaries of Arch Resources, subject to customary exceptions, will either constitute co-borrowers under or guarantors of the Inventory Facility (collectively with Arch Resources, the “Loan Parties”). The Inventory Facility is secured by first priority security interests in the ABL Priority Collateral (defined in the Inventory Facility) of the Loan Parties and second priority security interests in substantially all other assets of the Loan Parties, subject to customary exceptions (including an exception for the collateral that secures the Extended Securitization Facility).

Arch Resources has the right to prepay borrowings under the Inventory Facility at any time and from time to time in whole or in part without premium or penalty, upon written notice, except that any prepayment of such borrowings that bear interest at the LIBOR rate other than at the end of the applicable interest periods therefore shall be made with reimbursement for any funding losses and redeployment costs of the Lender resulting therefrom.

The Inventory Facility is subject to certain usual and customary mandatory prepayment events, including non-ordinary course asset sales or dispositions, subject to customary thresholds, exceptions (including exceptions for required prepayments under Arch Resources’s term loan facility) and reinvestment rights.

The Inventory Facility contains certain customary affirmative and negative covenants; events of default, subject to customary thresholds and exceptions; and representations, including certain cash management and reporting requirements that are customary for asset-based credit facilities. The Inventory Facility also includes a requirement to maintain Liquidity equal to or exceeding $100 million at all times. As of September 30, 2020, letters of credit totaling $29.2 million were outstanding under the facility with $14.8 million available for borrowings.

Equipment Financing

On March 4, 2020, the Company entered into an equipment financing arrangement accounted for as debt. The Company received $53.6 million in exchange for conveying an interest in certain equipment in operation at its Leer Mine and entered into a master lease arrangement for that equipment. The financing arrangement contains customary terms and events of default and provides for 48 monthly payments with an average interest rate of 6.34% maturing on March 4, 2024. Upon maturity, all interests in the subject equipment will revert back to the Company.

Tax Exempt Bonds

On July 2, 2020, the West Virginia Economic Development Authority (the “Issuer”) issued $53.1 million aggregate principal amount of Solid Waste Disposal Facility Revenue Bonds (Arch Resources Project), Series 2020 (the “Bonds”) pursuant to an Indenture of Trust dated as of June 1, 2020 (the “Indenture”) between the Issuer and Citibank, N.A., as trustee (the “Trustee”). The proceeds of the Bonds were loaned to the Company pursuant to a Loan Agreement dated as of June 1, 2020 between the Issuer and Arch. The Bonds are payable solely from payments to be made by the Company under the Loan Agreement as evidence by a Note from the Company to the Trustee. The proceeds of the Bonds were used to finance certain costs of the acquisition, construction, reconstruction, and equipping of solid waste disposal facilities at the Company’s Leer South development, and for capitalized interest and certain costs related to issuance of the Bonds.

The Bonds will bear interest payable each January 1 and July 1, commencing January 1, 2021, at an interest rate of 5% and have a final maturity of July 1, 2045; however, the Bonds are subject to mandatory tender on July 1, 2025 at a purchase price equal to 100% of the principal amount of the Bonds, plus accrued interest to July 1, 2025.

The Bonds are subject to redemption (i) in whole or in part at any time on or after January 1, 2025 at the option of the Issuer, upon the Company’s direction at a redemption price of par, plus interest accrued to the redemption date; and (ii) at par plus interest accrued to the redemption date from certain excess Bond proceeds as further described in the Indenture.

The Company’s obligations under the Loan Agreement are (i) except as otherwise described below, secured by first priority liens on and security interests in substantially all of the Company’s and Subsidiary Guarantors’ real property and other assets, subject to certain customary exceptions and permitted liens, and in any event excluding our accounts receivable and inventory; and (ii) jointly and severally guaranteed by the Subsidiary Guarantors, subject to customary exceptions.

The collateral securing the Company’s obligations under the Loan Agreement is substantially the same as the collateral securing the obligations under the Term Loan Debt Facility other than with respect to variances in certain real property collateral. The real property securing the Company’s obligations under the Loan Agreement includes a subset of the real property collateral securing the obligations under the Term Loan Debt Facility and includes only mortgages on substantially all of the Company’s revenue generating metallurgical coal real property and assets, including its mining complexes at Leer, Leer South, Mountain Laurel and Beckley in West Virginia. The Company is required to provide additional mortgages in the future to secure its obligations under the Loan Agreement due to the joint venture with Peabody not consummating.

The Loan Agreement contains certain affirmative covenants and representations, including but not limited to: (i) maintenance of a rating on the Bonds; (ii) maintenance of proper books of records and accounts; (iii) agreement to add additional guarantors to guarantee our obligations under the Loan Agreement in certain circumstances; (iv) procurement of customary insurance; and (v) preservation of legal existence and certain rights, franchises, licenses and permits. The Loan Agreement also contains certain customary negative covenants, which, among other things, and subject to certain exceptions, include restrictions on (i) release of collateral securing our obligations under the Loan Agreement; (ii) mergers and consolidations and disposition of assets, and (iii) restrictions on actions that may jeopardize the tax-exempt status of the Bonds.

The Loan Agreement contains customary events of default, subject to customary thresholds and exceptions, including, among other things, (i) nonpayment of principal, purchase price, interest and other fees (subject to certain cure periods), (ii) bankruptcy or insolvency proceedings relating to us; (iii) material inaccuracy of a representation or warranty at the time made, (iv) cross-events of default to indebtedness of at least $50 million, (v) cross defaults to the Indenture, the guaranty related to the Bonds or any related security documents.

As of September 30, 2020, Arch has received $38.1 million of the total bonds issues. The remaining $13.9 is held in trust and is recorded on the balance sheet as restricted cash. The remainder of the funds will be released as qualified expenditures are made over the next several quarters.

Interest Rate Swaps

The Company has entered into a series of interest rate swaps to fix a portion of the LIBOR interest rate within the term loan. The interest rate swaps qualify for cash flow hedge accounting treatment and as such, the change in the fair value of the interest rate swaps is recorded on the Company’s Condensed Consolidated Balance Sheet as an asset or liability with the effective portion of the gains or losses reported as a component of accumulated other comprehensive income and the ineffective portion reported in earnings. As interest payments are made on the term loan, amounts in accumulated other comprehensive income will be reclassified into earnings through interest expense to reflect a net interest on the term loan equal to the effective yield of the fixed rate of the swap plus 2.75% which is the spread on the revised LIBOR term loan. In the event that an interest rate swap is terminated prior to maturity, gains or losses in accumulated other comprehensive income will remain deferred and be reclassified into earnings in the periods which the hedged forecasted transaction affects earnings.

Below is a summary of the Company’s outstanding interest rate swap agreements designated as hedges as of September 30, 2020:

Notional Amount
(in millions)		Effective Date	Fixed Rate		Receive Rate	Expiration Date
$	200.0	June 30, 2020	2.249	%	1-month LIBOR	June 30, 2021
$	100.0	June 30, 2021	2.315	%	1-month LIBOR	June 30, 2023

The fair value of the interest rate swaps at September 30, 2020 is a liability of $4.5 million, which is recorded within Other noncurrent liabilities, with the offset to accumulated other comprehensive income on the Company’s Condensed Consolidated Balance Sheet. The Company realized $0.6 million and $1.5 million of losses during the three and nine months ended September 30, 2020, respectively, related to settlements of the interest rate swaps which was recorded to interest expense on the Company’s Condensed Consolidated Statement of Operations.

Fair Value Measurements

16. Fair Value Measurements

The hierarchy of fair value measurements assigns a level to fair value measurements based on the inputs used in the respective valuation techniques. The levels of the hierarchy, as defined below, give the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities and the lowest priority to unobservable inputs.

● Level 1 is defined as observable inputs such as quoted prices in active markets for identical assets. Level 1 assets include U.S. Treasury securities, and coal swaps and futures that are submitted for clearing on the New York Mercantile Exchange.

● Level 2 is defined as observable inputs other than Level 1 prices. These include quoted prices for similar assets or liabilities in an active market, quoted prices for identical assets and liabilities in markets that are not active, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities. The Company’s level 2 assets and liabilities include U.S. government agency securities, coal commodity contracts and interest rate swaps with fair values derived from quoted prices in over-the-counter markets or from prices received from direct broker quotes.

● Level 3 is defined as unobservable inputs in which little or no market data exists, therefore requiring an entity to develop its own assumptions. These include the Company’s commodity option contracts (coal, natural gas and heating oil) valued using modeling techniques, such as Black-Scholes, that require the use of inputs, particularly volatility, that are rarely observable. Changes in the unobservable inputs would not have a significant impact on the reported Level 3 fair values at September 30, 2020.

The table below sets forth, by level, the Company’s financial assets and liabilities that are recorded at fair value in the accompanying Condensed Consolidated Balance Sheet:

	September 30, 2020
	Total		Level 1		Level 2		Level 3
	(In thousands)
Assets:
Investments in marketable securities	$	63,128	$	15,306	$	47,822	$	—

Liabilities:
Derivatives	$	4,545	$	—	$	4,545	$	—

The Company’s contracts with its counterparties allow for the settlement of contracts in an asset position with contracts in a liability position in the event of default or termination. For classification purposes, the Company records the net fair value of all the positions with these counterparties as a net asset or liability. Each level in the table above displays the underlying contracts according to their classification in the accompanying Condensed Consolidated Balance Sheet, based on this counterparty netting.

The following table summarizes the change in the fair values of financial instruments categorized as Level 3.

Fair Value of Long-Term Debt

At September 30, 2020 and December 31, 2019, the fair value of the Company’s debt, including amounts classified as current, was $356.7 million and $308.0 million, respectively. Fair values are based upon observed prices in an active market, when available, or from valuation models using market information, which fall into Level 2 in the fair value hierarchy.

17. Earnings per Common Share

The Company computes basic net income (loss) per share using the weighted average number of common shares outstanding during the period. Diluted net income (loss) per share is computed using the weighted average number of common shares and the effect of potentially dilutive securities outstanding during the period. Potentially dilutive securities may consist of warrants, restricted stock units or other contingently issuable shares. The dilutive effect of outstanding warrants, restricted stock units and other contingently issuable shares is reflected in diluted earnings per

share by application of the treasury stock method. The weighted average share impact of warrants and restricted stock units that were excluded from the calculation of diluted shares due to the Company incurring a net loss for the three and nine month periods ending September 30, 2020 were 178,333 shares and 169,555 shares, respectively.

18. Workers Compensation Expense

The Company is liable under the Federal Mine Safety and Health Act of 1969, as subsequently amended, to provide for pneumoconiosis (occupational disease) benefits to eligible employees, former employees and dependents. The Company currently provides for federal claims principally through a self-insurance program. The Company is also liable under various state workers’ compensation statutes for occupational disease benefits. The occupational disease benefit obligation represents the present value of the actuarially computed present and future liabilities for such benefits over the employees’ applicable years of service.

In October 2019, the Company filed an application with the Office of Workers’ Compensation Programs (“OWCP”) within the Department of Labor for reauthorization to self-insure federal black lung benefits. In February 2020, the Company received a reply from the OWCP confirming Arch’s status to remain self-insured contingent upon posting additional collateral of $71.1 million within 30 days of receipt of the letter. The Company is currently appealing the ruling from the OWCP and has received an extension to self-insure during the appeal process. The Company is evaluating alternatives to self-insurance, including the purchase of commercial insurance to cover these claims.

In addition, the Company is liable for workers’ compensation benefits for traumatic injuries which are calculated using actuarially-based loss rates, loss development factors and discounted based on a risk free rate. Traumatic workers’ compensation claims are insured with varying retentions/deductibles, or through state-sponsored workers’ compensation programs.

Workers’ compensation expense consists of the following components:

	Three Months Ended September 30,				Nine Months Ended September 30,

Segment Information

Segment Information

21. Segment Information

The Company’s reportable business segments are based on two distinct lines of business, metallurgical and thermal, and may include a number of mine complexes. The Company manages its coal sales by market, not by individual mining complex. Geology, coal transportation routes to customers, and regulatory environments also have a significant impact on the Company’s marketing and operations management. Mining operations are evaluated based on Adjusted EBITDA, per-ton cash operating costs (defined as including all mining costs except depreciation, depletion, amortization, accretion on asset retirement obligations, and pass-through transportation expenses), and on other non-financial measures, such as safety and environmental performance. Adjusted EBITDA is not a measure of financial performance in accordance with generally accepted accounting principles, and items excluded from Adjusted EBITDA are significant in understanding and assessing the Company’s financial condition. Therefore, Adjusted EBITDA should not be considered in isolation, nor as an alternative to net income (loss), income (loss) from operations, cash flows from operations or as a measure of our profitability, liquidity or performance under generally accepted accounting principles. The Company uses Adjusted EBITDA to measure the operating performance of its segments and allocate resources to the segments. Furthermore, analogous measures are used by industry analysts and investors to evaluate the Company’s operating performance. Investors should be aware that the Company’s presentation of Adjusted EBITDA may not be comparable to similarly titled measures used by other companies. The Company reports its results of operations primarily through the following

reportable segments: Powder River Basin (PRB) segment containing the Company’s primary thermal operations in Wyoming; the Metallurgical (MET) segment, containing the Company’s metallurgical operations in West Virginia, and the Other Thermal segment containing the Company’s supplementary thermal operations in Colorado and Illinois.

On December 13, 2019, the Company closed on its definitive agreement to sell Coal-Mac LLC, an operating mine complex within the Company’s Other Thermal coal segment. Coal-Mac is included in the Other Thermal segment results below up to the date of the divestiture.

Operating segment results for the three and nine months ended September 30, 2020 and 2019, are presented below. The Corporate, Other and Eliminations grouping includes these charges: idle operations; change in fair value of coal derivatives and coal trading activities, net; corporate overhead; land management activities; other support functions; and the elimination of intercompany transactions.

22. Revenue Recognition

ASC 606-10-50-5 requires that entities disclose disaggregated revenue information in categories (such as type of good or service, geography, market, type of contract, etc.) that depict how the nature, amount, timing, and uncertainty of revenue and cash flow are affected by economic factors. ASC 606-10-55-89 explains that the extent to which an entity’s revenue is disaggregated depends on the facts and circumstances that pertain to the entity’s contracts with customers and that some entities may need to use more than one type of category to meet the objective for disaggregating revenue.

In general, the Company’s business segmentation is aligned according to the nature and economic characteristics of its coal and customer relationships and provides meaningful disaggregation of each segment’s results. The Company has further disaggregated revenue between North America and Seaborne revenues which depicts the pricing and contract differences between the two. North America revenue is characterized by contracts that typically have a term of one year or longer and typically the pricing is fixed; whereas Seaborne revenue generally is derived by spot or short term contracts with pricing determined at the time of shipment or based on a market index.

The Company has operating and financing leases for mining equipment, office equipment, office space and transloading terminals with remaining lease terms ranging from less than one year to approximately seven years. Some of these leases include both lease and non-lease components which are accounted for as a single lease component as the Company has elected the practical expedient to combine these components for all leases. As most of the leases do not provide an implicit rate, the Company calculated the ROU assets and lease liabilities using its secured incremental borrowing rate at the lease commencement date.

Recently Adopted Accounting Guidance

Recently Adopted Accounting Guidance

In June 2016, the FASB issued ASU 2016-13, “Financial Instruments-Credit Losses (Topic 326), Measurement of Credit Losses on Financial Instruments,” and also issued subsequent amendments to the initial guidance under ASU 2018-19, ASU 2019-04 and ASU 2019-05. The standard modifies the measurement approach for credit losses on financial instruments, including trade receivables, from an incurred loss method to a current expected credit loss method, otherwise known as “CECL.” The standard requires the measurement of expected credit losses to be based on relevant information, including historical experience, current conditions and a forecast that is supportable. The Company adopted the standard in the first quarter of 2020, with minimal impact to the Company’s financial results.

As part of the adoption, the Company reviewed its portfolio of available-for-sale debt securities in an unrealized loss position, and assessed whether it intends to sell, or it is more likely than not that it will be required to sell before recovery of its amortized cost basis. The Company determined that it currently does not intend to sell these securities before recovery of their amortized cost basis. Additionally, the Company evaluated whether the decline in fair value has resulted from credit losses or other factors by considering the extent to which the fair value is less than amortized cost, any changes to the rating of the security by a rating agency, and adverse conditions specifically related to the security, among other factors. If this assessment indicates that a credit loss exists, the Company compares the present value of the cash flows expected to be collected against the amortized cost basis. A credit loss is recorded if the present value of the cash flows is less than the amortized cost basis, limited by the amount that the fair value is less than the amortized cost basis. Upon adoption, the Company did not record an allowance for credit losses on its available-for-sale debt securities.

Additionally, the Company reviewed its open trade receivables arising from contractual coal sales. As part of its analysis, the Company performs periodic credit reviews of all active customers, reviews all trade receivables greater than 90 days past due, calculates historical loss rates and reviews current payment trends of all customers.

Recent Accounting Guidance Issued Not Yet Effective

In December 2019, the FASB issued ASU 2019-12, “Income Taxes (Topic 740) Simplifying the Accounting for Income Taxes.” ASU 2019-12 eliminates certain exceptions related to the approach for intraperiod tax allocation, the methodology for calculating income taxes in an interim period and the recognition of deferred tax liabilities for outside basis differences. The ASU is effective for public companies for fiscal years beginning after December 15, 2020, and interim periods therein with early adoption permitted. The Company is reviewing the provisions of the standard but does not expect a significant impact to the Company's financial statements.

In March 2020, the FASB issued ASU 2020-04, "Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting." The amendments provide optional guidance for a limited time to ease the potential burden in accounting for reference rate reform. The new guidance provides optional expedients and exceptions for applying U.S. GAAP to contracts, hedging relationships and other transactions affected by reference rate reform if certain criteria are met. The amendments apply only to contracts and hedging relationships that reference LIBOR or another reference rate expected to be discontinued due to reference rate reform. These amendments are effective immediately and may be applied prospectively to contract modifications made and hedging relationships entered into or evaluated on or before December 31, 2022. We are currently evaluating our contracts and the optional expedients provided by the new standard.
