6. Derivatives

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 during 2023. To protect the Company’s cash flows from increases in the price of diesel fuel for its operations, the Company has purchased heating oil call options. At June 30, 2023, the Company had protected the price of expected diesel fuel purchases for the remainder of 2023 with approximately 12 million gallons of heating oil call options remaining with an average strike price of $2.97 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 or on an exchange 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 June 30, 2023, the Company had no outstanding risk management derivatives.

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. The fair value and location of derivatives reflected in the accompanying Condensed Consolidated Balance Sheets are as follows:

Term Loan Facility

In 2017, the Company 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 loan provided under the Term Loan Debt Facility (the “Term Loan”) is subject to quarterly principal amortization payments in an amount equal to $750,000. The interest rate on the Term Loan Debt Facility is, at the option of Arch Resources, either (i) 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 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.

During the year ended December 31, 2022, the Company repaid $273.8 million of the Term Loan. The remaining balance of $5.0 million, as of June 30, 2023, remains outstanding as certain terms and conditions governing the Term Loan are incorporated into the Company’s outstanding indebtedness.

Accounts Receivable Securitization Facility

On August 3, 2022, 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 “Securitization Facility”), which supports the issuance of letters of credit and requests for cash advances. The amendment to the Securitization Facility increased the size of the facility from $110 million to $150 million of borrowing capacity and extended the maturity date to August 1, 2025.

Under the Securitization Facility, Arch Receivable, Arch Resources and certain of Arch Resources’ subsidiaries party to the Securitization Facility have granted to the administrator of the 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 June 30, 2023, letters of credit totaling $48.2 million were outstanding under the facility with $101.8 million available for borrowings.

Inventory-Based Revolving Credit Facility

On August 3, 2022, Arch Resources amended the senior secured inventory-based revolving credit facility in an aggregate principal amount of $50 million (the “Inventory Facility”). 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, plus (ii) the lesser of (x) 85% of the net orderly liquidation value of eligible parts and supplies inventory and (y) 35% of the amount

14

determined pursuant to clause (i), plus (iii) 100% of Arch Resources’ 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 August 3, 2025; maintained the minimum Liquidity requirement of $100 million and included provisions that reduce the advance rates for coal inventory and parts and supplies, depending on liquidity, as defined in the agreement.

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 June 30, 2023, letters of credit totaling $26.2 million were outstanding under the facility with $23.8 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.

On July 29, 2021, the Company entered into an additional equipment financing arrangement accounted for as debt. The Company received $23.5 million in exchange for conveying an interest in certain equipment in operation at its Powder River Basin operations and entered into a master lease arrangement for that equipment. The financing arrangement contains customary terms and events of default and provides for 42 monthly payments with an average implied interest rate of 7.35% maturing on February 1, 2025. Upon maturity, the Company will have the option to purchase the equipment.

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 “Tax Exempt Bonds”) pursuant to an Indenture of Trust dated as of June 1, 2020 (the “Indenture of Trust”) between the Issuer and Citibank, N.A., as trustee (the “Trustee”). On March 4, 2021, the Issuer issued an additional $45.0 million of Series 2021 Tax Exempt Bonds. The proceeds of the Tax Exempt Bonds were loaned to the Company pursuant to a Loan Agreement dated as of June 1, as supplemented by a First Amendment to Loan Agreement dated as of March 1, 2021 (collectively, the “Loan Agreement”), each between the Issuer and the Company. The Tax Exempt Bonds are payable solely from payments to be made by the Company under the Loan Agreement as evidenced by a Note from the Company to the Trustee. The proceeds of the Tax Exempt Bonds have been 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 Tax Exempt Bonds.

The Tax Exempt Bonds bear interest payable each January 1 and July 1, commencing January 1, 2021 for the Series 2020 and July 1, 2021 for the Series 2021, and have a final maturity of July 1, 2045; however, the Tax Exempt Bonds are subject to mandatory tender on July 1, 2025 at a purchase price equal to 100% of the principal amount of the Tax Exempt Bonds, plus accrued interest to July 1, 2025. The Series 2020 and Series 2021 Tax Exempt Bonds bear interest of 5% and 4.125%, respectively.

Convertible Debt

On November 3, 2020, the Company issued $155.3 million in aggregate principal amount of 5.25% convertible senior notes due 2025 (“Convertible Notes ” or “Convertible Debt”). The net proceeds from the issuance of the Convertible Notes, after deducting offering related costs of $5.1 million and cost of a “Capped Call Transaction” as defined below of $17.5 million, were approximately $132.7 million.

15

During the first half of 2023, the Company repurchased the remaining Convertible Notes with a principal amount of $13.2 million for aggregate consideration consisting of $58.4 million in cash. In connection with the repurchase for the six months ended June 30, 2023, the Company recognized a loss of $1.1 million. This amount is included as “Net loss resulting from early retirement of debt” in the accompanying Condensed Consolidated Income Statements.

Capped Call Transactions

In connection with the offering of the Convertible Notes, the Company entered into privately negotiated convertible note hedge transactions (collectively, the “Capped Call Transactions”). The Capped Call Transactions cover, subject to customary anti-dilution adjustments, the number of shares of the Company’s common stock that initially underlie the Convertible Notes.

The Capped Call Transactions are expected generally to reduce the potential dilution and/or offset any cash payments the Company is required to make in excess of the principal amount due upon conversion of the Convertible Notes in the event that the market price of the Company’s common stock is greater than the strike price of the Capped Call Transactions, which was initially $37.325 per share and the initial cap price was $52.255 per share. The initial call and cap prices are subject to adjustments under the terms of the underlying capped call agreements, including for various transactions such as the payment of dividends. The initial number of shares underlying the Capped Call Transactions is 4.2 million.

As of June 30, 2023, the Capped Call Transactions remain outstanding and have an intrinsic value of $62.1 million.

The Capped Call Transactions are separate transactions, in each case entered into between the Company and the respective Option Counterparty, and are not part of the terms of the Convertible Notes. As the Capped Call Transactions meet certain accounting criteria, they were classified as equity and are not accounted for as derivatives.

9. Income Taxes

The Company's effective tax rate for six months ended June 30, 2023 is based on its estimated full year effective tax rate, adjusted for discrete items. The effective tax rate for the three and six months ended June 30, 2023 was 14.3% and 15.4%, respectively. The effective tax rate for the three and six months ended June 30, 2023 differ from the U.S. federal statutory rate of 21%, primarily due to the income tax benefit for excess percentage depletion. The effective tax rate for the six months ended June 30, 2023 also includes the impact of discrete tax benefits related to equity compensation.

For the three and six months ended June 30, 2022, the Company's effective tax rate was 0.1% and 0.2%. The effective tax rate for the three and six months ended June 30, 2022 was impacted by the valuation allowance the Company maintained against its deferred tax assets until the fourth quarter of 2022.

10. 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.

16

● 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 (heating oil) valued using modeling techniques, such as Black-Scholes, that require the use of inputs, particularly volatility, that are rarely observable.

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:

	June 30, 2023
	Total		Level 1		Level 2		Level 3
	(In thousands)

Liabilities:
Derivatives	$	—	$	—	$	—	$	—

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 Company has contributed $138.7 million to a fund that will serve to defease the long-term asset retirement obligation for its thermal asset base; this amount is recorded as “Fund for asset retirement obligations” on the Condensed Consolidated Balance Sheets. The funds are invested in highly rated securities, such as U.S. Treasuries, which fall within Level 1 of the fair value hierarchy. The funds will only be utilized for final mine closure reclamation activities.

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

Fair Value of Long-Term Debt

At June 30, 2023 and December 31, 2022, the fair value of the Company’s debt, including amounts classified as current, was $137.7 million and $223.0 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.

11. Earnings per Common Share

The Company computes basic net income per share using the weighted average number of common shares outstanding during the period. Diluted net income 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, and convertible debt. The dilutive effect of outstanding warrants and restricted stock units is reflected in diluted earnings per share by application of the treasury stock method whereas the Convertible Debt uses the if converted method.

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

		Three Months Ended June 30,			Six Months Ended June 30,
		2023		2022	2023		2022
(In Thousands)
Net income attributable to common shares	$	77,353	$	407,563	$	275,461	$	679,435
Adjustment of interest expense attributable to Convertible Notes		—		1,691		108		3,999
Adjustment for inducement payments		—		4,697		—		4,697
Diluted net income attributable to common stockholders		77,353		413,951		275,569		688,131
Basic weighted average shares outstanding		18,406		16,801		18,165		16,124
Effect of dilutive securities		729		1,799		1,126		1,725
Convertible Notes (a)		—		2,852		168		3,513
Diluted weighted average shares outstanding		19,135		21,452		19,459		21,362

(a) Diluted weighted average common shares outstanding includes the dilutive effect had the Company's Convertible Notes been converted at the beginning of the year ended December 31, 2023. If converted by the holder, the Company may settle in cash, shares of the Company's common stock or a combination thereof, at the Company's election. The Capped Call Transaction is anti-dilutive and is excluded from the calculation of diluted earnings per share.

12. 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 its 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.

On January 18, 2023, the OWCP proposed revisions to regulations under the Black Lung Benefits Act governing authorization of self-insurers. The revisions seek to codify the practice of basing a self-insured operator’s security requirement on an actuarial assessment of its total present and future black lung liability. A material change to the regulations is the requirement that all self-insured operators must post security equal to 120% of their projected black lung liabilities.

The proposed regulations were posted to the Federal Register on January 19, 2023 with written comments to be accepted within 60 days of this date. Subsequently, the comment period was extended an additional 30 days.

If the above regulation is codified into law, the Company will be required to post additional collateral to maintain its self-insured status. The Company is evaluating alternatives to self-insurance, including the purchase of commercial insurance to cover these claims. Additionally, the Company is assessing the availability of surety bond capacity within the markets, additional sources of liquidity, and other items to satisfy the proposed regulations.

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 June 30,				Six Months Ended June 30,
	2023		2022		2023		2022
	(In thousands)
Self-insured occupational disease benefits:

Total workers’ compensation expense	$	5,004	$	4,956	$	8,956	$	9,819

(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 Income Statements on the line item “Non-service related pension and postretirement benefit costs.”

In February 2022, the Board of Directors approved the termination of the Company’s Cash Balance Pension Plan.  The Company has executed plan amendments regarding the termination and filed an Application for Determination for Terminating Pension Plan with the Internal Revenue Service ("IRS"), which was approved by the IRS during the first quarter of 2023.  The Company also prepared and filed appropriate notices and documents related to the Pension Plan's termination and wind-down with the Pension Benefit Guaranty Corporation ("PBGC"). Anticipated distributions to participants are expected during the second half of 2023.  In order to complete the termination of the plan, the Company anticipates making a final contribution to the plan of approximately $6.0 - $10 million during the third quarter.

14. 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.

The Company is a party to numerous 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.

In the normal course of business, the Company is a party to certain financial instruments with off-balance sheet risk, such as bank letters of credit, performance or surety bonds, and other guarantees and indemnities related to the obligations of affiliated entities which are not reflected in the Company’s Condensed Consolidated Balance Sheets. However, the underlying liabilities that they secure, such as asset retirement obligations, workers’ compensation liabilities, and other obligations, are reflected in the Company’s Condensed Consolidated Balance Sheets.

20

As of June 30, 2023, the Company had outstanding surety bonds with a face amount of $553.0 million to secure various obligations and commitments and $74.4 million of letters of credit under its Securitization and Inventory Facilities used to collateralize certain obligations. The Company had posted $5.6 million in cash collateral related to various obligations; this amount is recorded within “Other noncurrent assets” on the Condensed Consolidated Balance Sheets.

As of June 30, 2023, the Company’s reclamation-related obligations of $243.2 million were supported by surety bonds of $456.1 million. The Company has posted $0.6 million in cash collateral related to reclamation surety bonds. This amount is recorded within “Other noncurrent assets” on the Condensed Consolidated Balance Sheets. Additionally, in the second quarter of 2023, the Company contributed an additional $1.6 million representing interest earned to a fund that will serve to defease the long-term asset retirement obligation for its thermal asset base bringing the total to $138.7 million as of June 30, 2023. This amount is recorded as “Fund for asset retirement obligations” on the Condensed Consolidated Balance Sheets.

15. 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 and coal quality, 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, divided by segment tons sold), 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, income 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: Metallurgical (MET) segment, containing the Company’s metallurgical operations in West Virginia, and the Thermal segment containing the Company’s thermal operations in Wyoming and Colorado.

Reporting segment results for the three and six months ended June 30, 2023 and 2022 are presented below. The Corporate, Other, and Eliminations grouping includes these charges: idle operations; change in fair value of coal derivatives, net; corporate overhead; land management activities; other support functions; and the elimination of intercompany transactions.

16. Revenue Recognition

ASC 606-10-50-5 requires that entities disclose disaggregated revenue information in categories (such as type of goods or services, 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 with 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 an index-based pricing mechanism.

17. 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 four 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 “right-of-use” (“ROU”) assets and lease liabilities using its secured incremental borrowing rate at the lease commencement date.

As of June 30, 2023 and December 31, 2022, the Company had the following ROU assets and lease liabilities within its Condensed Consolidated Balance Sheets:

Overview

Our results for the three months ended June 30, 2023 were pressured by softening of global metallurgical and thermal coal markets. Despite the current softness, coal markets, particularly coking coal markets, have remained above previous long-term average levels. The Russian invasion of Ukraine continues to distort previously established trading patterns in the global energy markets. However, slow global economic growth, and the generally mild winter heating season in Europe and much of North America has limited overall energy demand and moderated both metallurgical and thermal coal markets. In the Pacific, while China has lifted the suspension of purchases of Australian coal, traditional trade flows in coal markets are far from being reestablished. General global inflationary pressure has moderated, following tighter monetary policies from many nations’ central banks. However, inflation may not be completely contained, and the timing and magnitude of further tightening of monetary policy remains uncertain. On a macro level, the outlook for global economic growth is uncertain, but supply constraints continue to support global metallurgical and thermal coal markets to varying degrees.

The February 2022 Russian invasion of Ukraine continues to significantly disrupt previously established global coal and energy trading patterns, driving Russian products into Asian markets at discounted prices. Ongoing bans on the import of Russian coal by the European Union, the United Kingdom, Japan, and other nations continues to pressure availability of supply to these markets. In particular, the European Union’s ban on importation of Russian coal, which became effective on August 10, 2022, and the related restriction of Russian natural gas supplies into Europe, contributed to historically high thermal coal prices in the international markets during 2022. The mild winter heating season in Europe prevented anticipated natural gas and electricity shortages, allowing European energy markets to moderate. This moderation of European energy prices has led to the reopening of several Basic Oxygen Furnace (“BOF”) steel plants in Europe that had been idled during 2022. While the outlook for steel production and coking coal demand in Europe has improved, currently broad economic weakness constrains demand for finished steel products.

Since the fourth quarter of 2020, China had effectively banned the import of coking coal and thermal coal, among other products, from Australia, the largest global exporter of coking coal. China has since lifted this ban on Australian coal. The lifting of this ban is slowly impacting trade patterns, as Australian coal begins to flow into China once again. We expect international coking and thermal coal markets to remain volatile while a new equilibrium is sought in global trading patterns. Russian coking coal, offered at discounts to published indices, remains a larger share of Chinese and Indian imports compared to historical levels, but logistical, financial, and quality constraints exist as potential barriers to further increase in Russian supplies to these markets. Chinese domestic coking coal production, and overland imports from Mongolia, have also increased significantly. However, Australian coking coal supply has continued to decline, and North American coking coal supply has only increased incrementally, despite coking coal prices staying persistently above long-term historical averages. There are also some early signs that the current relative softness in international coking coal markets may be putting financial pressure on some high cost producers.

Some new coking coal supply has been added to the market, and more is planned. However, production and logistical disruptions, continue to constrain supply. The duration of specific supply disruptions is unknown. We believe that underinvestment in the sector in recent years underlies longer-term market dynamics. Overall, underinvestment in the sector appears likely to persist, despite favorable markets, as government policies and diminished access to traditional capital markets, limits investment in the sector. In the current macroeconomic environment, we expect coking coal prices to remain volatile. Longer term, we believe continued limited global capital investment in new coking coal production capacity, normal reserve depletion, and an eventual return to economic growth will provide support to coking coal markets.

During the first six months of 2023, domestic thermal coal consumption was pressured by a mild winter heating season in most of the heavily populated areas of the United States, and falling natural gas prices. Currently, natural gas prices are at levels that allow it to economically dispatch ahead of thermal coal. We have firm sales commitments for the current year for our thermal segment at volume levels that provide for economic operation, even if some volume is deferred. Longer term, we continue to believe thermal coal demand in the United States will remain pressured by continuing increases in subsidized renewable generation sources, particularly wind and solar, planned retirements of coal

27

fueled generating facilities, and competition from natural gas. Despite some moderation, international thermal coal markets remain above long term historical averages, supporting continued export opportunities for our thermal operations.

During the first three months of 2023, we encountered adverse geologic conditions at our West Elk thermal coal operation. These conditions continue to impact both our expected volumes and coal quality. Due to this situation, we have issued force majeure notices to our West Elk customers and logistics providers with shipments affected by that event. We continue to communicate with these customers and logistics providers, and to manage through the adverse area to mitigate impacts to the extent possible.

We continue to pursue strategic alternatives for our thermal assets, including, among other things, potential divestiture. We are concurrently shrinking our operational footprint at our Powder River Basin operations. During the first six months of 2023, we contributed $2.7 million to our fund for asset retirement obligations, representing interest earned, bringing our total to $138.7 million. Additionally, we performed approximately $8.5 million of reclamation work at our thermal operations in the first six months of 2023. We plan to continue to grow the thermal mine reclamation fund through both interest earnings and contributions from cash flow of $10 to $20 million over the next several quarters. We continue to exercise our operational flexibility to maximize cash generation from our thermal operations. Currently, our planned production levels correspond with existing commitments. Longer term, we will maintain our focus on aligning our thermal production rates with the expected secular decline in domestic thermal coal demand and viable export opportunities, while adjusting our thermal operating plans to minimize future cash requirements and maintain flexibility to react to short-term market fluctuations. We continue to streamline 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 June 30, 2023 and 2022

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 June 30, 2023 and 2022:

	Three Months Ended June 30,
	2023		2022		(Decrease) / Increase
	(In thousands)
Coal sales	$	757,294	$	1,133,358	$	(376,064)
Tons sold		18,713		19,906		(1,193)

On a consolidated basis, coal sales in the second quarter of 2023 were approximately $376.1 million, or 33.2%, less than in the second quarter of 2022, while tons sold decreased approximately 1.2 million tons, or 6.0%. Coal sales from Metallurgical operations decreased approximately $272.7 million, primarily due to decreased pricing and offset partially by increased volume. Thermal coal sales decreased approximately $103.3 million due to decreased pricing and volume. See the 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 June 30, 2023 and 2022:

	Three Months Ended June 30,
	2023		2022		Increase (Decrease) in Net Income
	(In thousands)
Cost of sales (exclusive of items shown separately below)	$	606,127	$	639,760	$	33,633
Depreciation, depletion and amortization		36,077		32,780		(3,297)
Accretion on asset retirement obligations		5,293		4,430		(863)
Change in fair value of coal derivatives, net		2,869		1,877		(992)
Selling, general and administrative expenses		22,791		26,516		3,725
Other operating (income) expense, net		(4,879)		5,238		10,117
Total costs, expenses and other	$	668,278	$	710,601	$	42,323

Cost of sales. Our cost of sales for the second quarter of 2023 decreased approximately $33.6 million, or 5.3%, versus the second quarter of 2022. The decrease in cost of sales is directly attributable to decreased transportation costs of approximately $27.3 million, and decreased sales sensitive costs of approximately $14.9 million offset partially by increased compensation and related benefit costs of approximately $6.0 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 second quarter of 2023 versus the second quarter of 2022 primarily related to increased amortization within the Thermal segment related to the annual re-costing exercise on asset retirement obiligations completed during the fourth quarter of 2022.

Accretion on asset retirement obligations. The increase in accretion expense in the second quarter of 2023 versus the second quarter of 2022 is primarily related to the results of our annual recosting exercise completed during the fourth quarter of 2022.

29

Change in fair value of coal derivatives, net. The costs in the second quarter of 2023 versus the second quarter of 2022 are primarily related to mark-to-market losses on coal derivatives that are used to hedge our price risk for international thermal coal shipments.

Selling, general and administrative expenses. The decrease in selling, general and administrative expenses in the second quarter of 2023 versus the second quarter of 2022 was due to a decrease in compensation related expenses.

Other operating (income) expense, net. The increase in other operating income, net in the second quarter of 2023 versus the expense in the second quarter of 2022, consists primarily of the net favorable impact of certain coal derivative settlements of approximately $21.0 million, partially offset by the unfavorable impact of mark to market movements on heating oil positions of approximately $7.8 million.

Nonoperating expenses. The following table summarizes our nonoperating expenses during the three months ended June 30, 2023 and 2022:

	Three Months Ended June 30,
	2023		2022		Increase (Decrease) in Net Income

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 six months ended June 30, 2023 and 2022:

	Six Months Ended June 30,
	2023		2022		(Decrease) / Increase
	(In thousands)
Coal sales	$	1,627,225	$	2,001,294	$	(374,069)
Tons sold		37,890		39,644		(1,754)

On a consolidated basis, coal sales in the first half of 2023 were approximately $374.1 million, or 18.7%, less than in the first half of 2022, while tons sold decreased approximately 1.8 million tons, or 4.4% all of which was in the

30

thermal segment. Coal sales from Metallurgical operations decreased approximately $208.7 million primarily due to lower realized pricing, partially offset by increased volume. Thermal coal sales decreased approximately $165.3 million due to decreased pricing and volume. See the 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 six months ended June 30, 2023 and 2022:

	Six Months Ended June 30,
	2023		2022		Increase (Decrease) in Net Income
	(In thousands)
Cost of sales (exclusive of items shown separately below)	$	1,177,864	$	1,147,985	$	(29,879)
Depreciation, depletion and amortization		71,556		64,990		(6,566)
Accretion on asset retirement obligations		10,585		8,860		(1,725)
Change in fair value of coal derivatives, net		1,407		17,396		15,989
Selling, general and administrative expenses		48,813		53,164		4,351
Other operating (income) expense, net		(8,586)		1,799		10,385
Total costs, expenses and other	$	1,301,639	$	1,294,194	$	(7,445)

Cost of sales. Our cost of sales for the first half of 2023 increased approximately $29.9 million, or 2.6%, versus the first half of 2022. The increase in cost of sales is directly attributable to general inflationary pressure on most goods and services, which consists of increased repairs and supplies costs of approximately $36.9 million and increased compensation costs of approximately $22.2 million offset by decreased transportation costs of approximately $31.1 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 half of 2023 versus the first half of 2022 primarily related to increased amortization within the Thermal segment related to the annual re-costing exercise on asset retirement obiligations completed during the fourth quarter of 2022.

Accretion on asset retirement obligations. The increase in accretion expense in the first half of 2023 versus the first half of 2022 is primarily related to the results of our annual recosting exercise completed during the fourth quarter of 2022.

Change in fair value of coal derivatives and coal trading activities, net. The costs in both the first half of 2023 and 2022 are primarily related to mark-to-market losses on coal derivatives that are used to hedge our price risk for international thermal coal shipments.

Selling, general and administrative expenses. Selling, general and administrative expenses in the first half of 2023 decreased versus the first half of 2022, primarily due to decreased compensation costs of approximately $5.5 million, primarily related to higher incentive compensation accruals recorded in the first half of 2022, partially offset by an increase in professional services of approximately $1.4 million.

Other operating (income) expense, net. The income in other operating (income) expense, net in the first half of 2023 versus the expense in first half of 2022 is primarily due to the net favorable impact of certain coal derivative settlements of approximately $32.7 million, partially offset by the unfavorable impact of mark to market movements on heating oil positions of approximately $15.9 million, an approximate $2.2 million reduction in our equity investment and $1.8 million in liquidated damages on unused port capacity relating to our thermal operations.

Nonoperating expenses. The following table summarizes our nonoperating expenses during the six months ended June 30, 2023 and 2022:

Total non-operating expenses	$	59	$	(15,081)	$	15,140

Net loss resulting from early retirement of debt. In the first half of 2022, we repaid $272.3 million of our Term Loan and entered into privately negotiated exchanges for approximately $125.2 million principal amount of our Convertible Notes. As a result of these transactions, we recorded losses of $13.7 million resulting from early debt extinguishment expenses. For further information, see Note 8, “Debt and Financing Arrangements” to the Condensed Consolidated Financial Statements.

Provision for income taxes. The following table summarizes our provision for income taxes during the six months ended June 30, 2023 and 2022:

Operational Performance

Three and Six Months Ended June 30, 2023 and 2022

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, divided by segment tons sold), and on other non-financial measures, such as safety and environmental performance. Adjusted EBITDA is defined as net income attributable to us before the effect of net interest expense, income taxes, depreciation, depletion and amortization, the amortization of sales contracts, the accretion on asset retirement obligations and nonoperating income (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, income 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 our 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 six months ended June 30, 2023 and June 30, 2022.

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.

Metallurgical — Adjusted EBITDA for the three and six months ended June 30, 2023 decreased from the three and six months ended June 30, 2022 due to decreased coal sales per ton sold, partially offset by increased tons sold and lower cash cost per ton sold. As discussed previously in the “Overview,” coal sales per ton sold declined from the historically high levels of the prior year periods as weak global economic growth muted demand for finished steel products, which exerted downward pressure on international coking coal prices. Tons sold increased and cash cost per ton sold decreased as each of our metallurgical mines increased production volume over the prior year periods. In particular, our Leer South mine productivity improved significantly, as the prior year periods were impacted by adverse geologic conditions. Cash cost per ton sold decreased versus the prior year periods despite continued inflationary pressure on most goods and services, due to the increase in production volume and decreased taxes and royalties that are based on a percentage of coal sales per ton sold.

33

Our Metallurgical segment sold 2.3 million tons of coking coal and 0.2 million tons of associated thermal coal in the three months ended June 30, 2023, compared to 2.1 million tons of coking coal and 0.1 million tons of associated thermal coal in the three months ended June 30, 2022. For the six months ended June 30, 2023, we sold 4.3 million tons of coking coal and 0.3 million tons of associated thermal coal, compared to 3.5 million tons of coking coal and 0.2 million tons of associated thermal coal in the six months ended June 30, 2022. Longwall operations accounted for approximately 72% of our shipment volume in the three months ended June 30, 2023 and approximately 76% of our shipment volume in the six months ended June 30, 2023, compared to approximately 76% of our shipment volume in the three months ended June 30, 2022 and approximately 75% of our shipment volume in the six months ended June 30, 2022.

Thermal — Adjusted EBITDA for the three and six months ended June 30, 2023 decreased versus the three and six months ended June 30, 2022, due to decreased coal sales per ton sold, decreased tons sold, and increased cash cost per ton sold. All of these metrics were adversely impacted in the current three and six month periods by the adverse geologic conditions encountered at our West Elk operation as discussed in the Overview section above. Additionally, the decline in coal sales per ton sold in the current year periods is related to the roll off and replacement of some high-priced domestic business that was contracted for the prior year periods during the second half of 2021, which was a period of very strong domestic thermal coal markets. The tons sold decrease in the current year periods is related to rail service constraints early in the year, and the generally mild winter heating season and the related significant drop in natural gas prices versus the prior year periods. Cash cost per ton sold increased primarily due to the decrease in tons sold.

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 Income Statements, 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 statements 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 Net Income to Segment Adjusted EBITDA

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 us before the effect of net interest expense, income taxes, depreciation, depletion and amortization, the accretion on asset retirement obligations and nonoperating (income) 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, income 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. 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, we believe it remains important to take a prudent approach to managing our balance sheet and liquidity. Additionally, banks and other lenders have become increasingly unwilling to provide financing to coal producers, especially those with significant thermal coal exposure. Due to the nature of our business, we may be limited in accessing debt capital markets or obtaining additional bank financing, or the cost of accessing this financing could become more expensive.

Our priority is to improve our financial position through enhancing liquidity and reducing our debt and other liabilities, while returning significant value to our stockholders. During the first half of 2023, capital expenditures were approximately $76.6 million, and we expect our capital spending to remain at maintenance levels for the foreseeable future. During the first half of 2023, we repurchased $13.2 million in principal amount of our Convertible Notes with consideration of $58.4 and received approximately $43.8 million for warrants that were exercised. We ended the second quarter of 2023 with cash, cash equivalents and short-term investments of $235.1 million and total liquidity of $361.2 million. We believe our current liquidity level is sufficient to fund our business and meet both our short-term (the next twelve months) and reasonably foreseeable long-term requirements and obligations including our recently enacted variable rate dividend policy. We expect to maintain minimum liquidity levels of approximately $250 million to $300 million, with a substantial portion of that held in cash. In addition, we expect to hold additional cash at the end of each quarter in an amount that represents a substantial portion of the following quarter’s dividend payment.

We believe we have significantly increased our future cash-generating capabilities, and as a result, in the second quarter of 2022, we launched a comprehensive capital return program that returns 50% of the prior quarter discretionary cash flow to stockholders via a variable rate cash dividend and reserves the remaining 50% for potential share buybacks, special dividends, the repurchase of potentially dilutive securities, and capital preservation. For the six months ended June 30, 2023, we paid approximately $111.9 million to our stockholders in the form of dividends and spent approximately $93.8 million to repurchase our common stock. Any future dividends and all of these potential uses of capital are subject to board approval and declaration.

On January 18, 2023, the Office of Workers’ Compensation Programs (“OWCP”) proposed revisions to regulations under the Black Lung Benefits Act governing authorization of self-insurers. The revisions seek to codify the practice of basing a self-insured operator’s security requirement on an actuarial assessment of its total present and future black lung liability. A material change to the regulations is the requirement that all self-insured operators must post security equal to 120% of their projected black lung liabilities. The proposed regulations were posted to the Federal Register on January 19, 2023 with written comments to be accepted within 60 days of this date. Subsequently, the comment period was extended an additional 30 days. The revisions proposed by the OWCP were a material deviation from their bulletin issued in December 2020 that would have required the majority of coal operators to post security equal to 70% of their projected black lung liabilities, which, at the time, equated to the Company posting additional collateral of $71.1 million. If the above regulation is codified into law, the Company will be required to post additional collateral to maintain its self-insured status. The Company is evaluating alternatives to self-insurance, including the purchase of commercial insurance to cover these claims. Additionally, the Company is assessing additional sources of liquidity and other items to satisfy the proposed regulations. Any of these outcomes will require additional collateral and would reduce our available liquidity.

Based on the second quarter discretionary cash flow, a combined fixed and variable dividend payment of $3.97 per share will be made to stockholders of record as of Augst 31, 2023, payable on September 15, 2023.

The table below summarizes our second quarter discretionary cash flow and total dividend payout:

During the second quarter of 2022, the Board of Directors increased the remaining outstanding authorization for share repurchases to $500 million. During the quarter ended June 30, 2023, we repurchased shares of our common stock for approximately $73.0 million bringing total repurchases to 11,961,295 shares for approximately $1.1 billion since the inception of the program in 2017. 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. Our share repurchase program may be amended, suspended or discontinued at any time and does not commit us to repurchase shares of our common stock.

The table below summarizes our availability under our credit facilities as of June 30, 2023:

					Letters of
			Borrowing		Credit				Contractual
	Face Amount		Base		Outstanding		Availability		Expiration
	(Dollars in thousands)
Securitization Facility	$	150,000	$	150,000	$	48,243	$	101,757		August 1, 2025
Inventory Facility		50,000		50,000		26,200		23,800		August 3, 2025
Total	$	200,000	$	200,000	$	74,443	$	125,557

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.

Contractual Obligations

Our contractual obligations include long-term debt and related interest, leases, coal lease rights, coal purchase obligations, and unconditional purchase obligations. As discussed above, we have reduced our long-term debt by repurchasing approximately $13.2 million principal amount of our Convertible Notes during the first six months of 2023. There have been no other material changes to our contractual obligations from our Annual Report on Form 10-K for the year ended December 31, 2022.

Off-Balance Sheet Arrangements

In the normal course of business, we are a party to certain off-balance sheet arrangements. These arrangements include guarantees, indemnifications, financial instruments with off-balance sheet risk, such as bank letters of credit and performance or surety bonds. Liabilities related to these arrangements are not reflected in our condensed consolidated balance sheets, and we do not expect any material adverse effects on our financial condition, results of operations or cash flows to result from these off-balance sheet arrangements. We use a combination of surety bonds and letters of credit to secure our financial obligations for reclamation, workers’ compensation, coal lease obligations and other obligations. There have been no material changes to our off-balance sheet arrangements from our Annual Report on Form 10-K for the year ended December 31, 2022. For further information regarding off-balance sheet arrangements, see Note 14, “Commitments and Contingencies” to the Condensed Consolidated Financial Statements.

Cash Flow

The following is a summary of cash provided by or used in each of the indicated types of activities during the six months ended June 30, 2023 and 2022:

	Six Months Ended June 30,
	2023		2022
(In thousands)
Cash provided by (used in):
Operating activities	$	322,886	$	561,167
Investing activities		(83,491)		(42,187)
Financing activities		(273,962)		(562,231)

Cash provided by operating activities decreased approximately $238 million compared to the prior year, primarily due to a decrease in results from operations discussed in the “Overview” and “Operational Performance” sections above offset by an increase in working capital in excess of prior year’s of approximately $50 million.

Cash used in investing activities increased in the six months ended June 30, 2023 versus the six months ended June 30, 2022, primarily due to increased capital expenditures of approximately $23.4 million for maintenance capital and an increase in net short-term investment activity of approximately $10.7 million.

Cash used in financing activities declined $288.3 million compared to the prior period due to a decrease of approximately $337.4 million in overall debt payments compared to prior year, a reduction in dividends paid of approximately $42.7 million, offset by an increase in share repurchases of $93.8 million.

Critical Accounting Estimates

We prepare our financial statements in accordance with accounting principles that are generally accepted in the United States. The preparation of these financial statements requires management to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses as well as the disclosure of contingent assets and liabilities. Management bases our estimates and judgments on historical experience and other factors that are believed to be reasonable under the circumstances. There have been no material changes to our critical accounting estimates from our Annual Report on Form 10-K for the year ended December 31, 2022.

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 2023 were as follows as of June 30, 2023:

	2023
	Tons	$ per ton
Metallurgical	(in millions)
Committed, North America Priced Coking	1.7	$	183.57
Committed, North America Unpriced Coking	0.1
Committed, Seaborne Priced Coking	3.5		179.01
Committed, Seaborne Unpriced Coking	2.8
Committed, Priced Thermal	0.4		43.43
Committed, Unpriced Thermal	—
Thermal
Committed, Priced	67.9	$	17.40
Committed, Unpriced	1.0

We have exposure to price risk for supplies that are used directly or indirectly in the normal course of production, such as diesel fuel, steel, explosives and other items. We manage our risk for these items through strategic sourcing contracts in normal quantities with our suppliers. We may sell or purchase forward contracts, swaps and options in the over-the-counter market in order to manage its exposure to price risk related to these items.

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 June 30, 2023, the Company had protected the price of expected diesel fuel purchases for the remainder of 2023 with approximately 12 million gallons of heating oil call options with an average strike price of $2.97 per 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 June 30, 2023. 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

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.

Item 1A. Risk Factors

There have been no material changes to the “Risk Factors” disclosed in Item 1A of our Annual Report on Form 10-K for the year ended December 31, 2022.

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

During the second quarter of 2022, the Board of Directors increased the remaining outstanding authorization for share repurchases to $500 million. The timing of any future share purchases, and the ultimate number of shares of our common stock 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.

A summary of our common stock repurchases during the three months ended June 30, 2023 is set forth in the table below:

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 June 30, 2023 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 June 30, 2023) 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.

The aggregate fair value of investments with unrealized losses that had been owned for less than a year was $20.5 million and $22.6 million at June 30, 2023 and December 31, 2022, respectively. The aggregate fair value of investments with unrealized losses that were owned for over a year was $0.0 million at both June 30, 2023 and December 31, 2022. The unrealized losses in the Company’s portfolio at June 30, 2023 are the result of normal market fluctuations. The Company does not intend to sell these investments before recovery of their amortized cost base.

The debt securities outstanding at June 30, 2023 have maturity dates ranging from the third quarter of 2023 through the third quarter of 2024. 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 if needed.

6. Derivatives

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 during 2023. To protect the Company’s cash flows from increases in the price of diesel fuel for its operations, the Company has purchased heating oil call options. At June 30, 2023, the Company had protected the price of expected diesel fuel purchases for the remainder of 2023 with approximately 12 million gallons of heating oil call options remaining with an average strike price of $2.97 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 or on an exchange 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 June 30, 2023, the Company had no outstanding risk management derivatives.

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. The fair value and location of derivatives reflected in the accompanying Condensed Consolidated Balance Sheets are as follows:

Term Loan Facility

In 2017, the Company 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 loan provided under the Term Loan Debt Facility (the “Term Loan”) is subject to quarterly principal amortization payments in an amount equal to $750,000. The interest rate on the Term Loan Debt Facility is, at the option of Arch Resources, either (i) 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 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.

During the year ended December 31, 2022, the Company repaid $273.8 million of the Term Loan. The remaining balance of $5.0 million, as of June 30, 2023, remains outstanding as certain terms and conditions governing the Term Loan are incorporated into the Company’s outstanding indebtedness.

Accounts Receivable Securitization Facility

On August 3, 2022, 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 “Securitization Facility”), which supports the issuance of letters of credit and requests for cash advances. The amendment to the Securitization Facility increased the size of the facility from $110 million to $150 million of borrowing capacity and extended the maturity date to August 1, 2025.

Under the Securitization Facility, Arch Receivable, Arch Resources and certain of Arch Resources’ subsidiaries party to the Securitization Facility have granted to the administrator of the 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 June 30, 2023, letters of credit totaling $48.2 million were outstanding under the facility with $101.8 million available for borrowings.

Inventory-Based Revolving Credit Facility

On August 3, 2022, Arch Resources amended the senior secured inventory-based revolving credit facility in an aggregate principal amount of $50 million (the “Inventory Facility”). 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, plus (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), plus (iii) 100% of Arch Resources’ 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 August 3, 2025; maintained the minimum Liquidity requirement of $100 million and included provisions that reduce the advance rates for coal inventory and parts and supplies, depending on liquidity, as defined in the agreement.

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 June 30, 2023, letters of credit totaling $26.2 million were outstanding under the facility with $23.8 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.

On July 29, 2021, the Company entered into an additional equipment financing arrangement accounted for as debt. The Company received $23.5 million in exchange for conveying an interest in certain equipment in operation at its Powder River Basin operations and entered into a master lease arrangement for that equipment. The financing arrangement contains customary terms and events of default and provides for 42 monthly payments with an average implied interest rate of 7.35% maturing on February 1, 2025. Upon maturity, the Company will have the option to purchase the equipment.

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 “Tax Exempt Bonds”) pursuant to an Indenture of Trust dated as of June 1, 2020 (the “Indenture of Trust”) between the Issuer and Citibank, N.A., as trustee (the “Trustee”). On March 4, 2021, the Issuer issued an additional $45.0 million of Series 2021 Tax Exempt Bonds. The proceeds of the Tax Exempt Bonds were loaned to the Company pursuant to a Loan Agreement dated as of June 1, as supplemented by a First Amendment to Loan Agreement dated as of March 1, 2021 (collectively, the “Loan Agreement”), each between the Issuer and the Company. The Tax Exempt Bonds are payable solely from payments to be made by the Company under the Loan Agreement as evidenced by a Note from the Company to the Trustee. The proceeds of the Tax Exempt Bonds have been 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 Tax Exempt Bonds.

The Tax Exempt Bonds bear interest payable each January 1 and July 1, commencing January 1, 2021 for the Series 2020 and July 1, 2021 for the Series 2021, and have a final maturity of July 1, 2045; however, the Tax Exempt Bonds are subject to mandatory tender on July 1, 2025 at a purchase price equal to 100% of the principal amount of the Tax Exempt Bonds, plus accrued interest to July 1, 2025. The Series 2020 and Series 2021 Tax Exempt Bonds bear interest of 5% and 4.125%, respectively.

Convertible Debt

On November 3, 2020, the Company issued $155.3 million in aggregate principal amount of 5.25% convertible senior notes due 2025 (“Convertible Notes ” or “Convertible Debt”). The net proceeds from the issuance of the Convertible Notes, after deducting offering related costs of $5.1 million and cost of a “Capped Call Transaction” as defined below of $17.5 million, were approximately $132.7 million.

During the first half of 2023, the Company repurchased the remaining Convertible Notes with a principal amount of $13.2 million for aggregate consideration consisting of $58.4 million in cash. In connection with the repurchase for the six months ended June 30, 2023, the Company recognized a loss of $1.1 million. This amount is included as “Net loss resulting from early retirement of debt” in the accompanying Condensed Consolidated Income Statements.

Capped Call Transactions

In connection with the offering of the Convertible Notes, the Company entered into privately negotiated convertible note hedge transactions (collectively, the “Capped Call Transactions”). The Capped Call Transactions cover, subject to customary anti-dilution adjustments, the number of shares of the Company’s common stock that initially underlie the Convertible Notes.

The Capped Call Transactions are expected generally to reduce the potential dilution and/or offset any cash payments the Company is required to make in excess of the principal amount due upon conversion of the Convertible Notes in the event that the market price of the Company’s common stock is greater than the strike price of the Capped Call Transactions, which was initially $37.325 per share and the initial cap price was $52.255 per share. The initial call and cap prices are subject to adjustments under the terms of the underlying capped call agreements, including for various transactions such as the payment of dividends. The initial number of shares underlying the Capped Call Transactions is 4.2 million.

As of June 30, 2023, the Capped Call Transactions remain outstanding and have an intrinsic value of $62.1 million.

The Capped Call Transactions are separate transactions, in each case entered into between the Company and the respective Option Counterparty, and are not part of the terms of the Convertible Notes. As the Capped Call Transactions meet certain accounting criteria, they were classified as equity and are not accounted for as derivatives.

The Company's effective tax rate for six months ended June 30, 2023 is based on its estimated full year effective tax rate, adjusted for discrete items. The effective tax rate for the three and six months ended June 30, 2023 was 14.3% and 15.4%, respectively. The effective tax rate for the three and six months ended June 30, 2023 differ from the U.S. federal statutory rate of 21%, primarily due to the income tax benefit for excess percentage depletion. The effective tax rate for the six months ended June 30, 2023 also includes the impact of discrete tax benefits related to equity compensation.

For the three and six months ended June 30, 2022, the Company's effective tax rate was 0.1% and 0.2%. The effective tax rate for the three and six months ended June 30, 2022 was impacted by the valuation allowance the Company maintained against its deferred tax assets until the fourth quarter of 2022.

Fair Value Measurements

10. 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 (heating oil) valued using modeling techniques, such as Black-Scholes, that require the use of inputs, particularly volatility, that are rarely observable.

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:

	June 30, 2023
	Total		Level 1		Level 2		Level 3

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 Company has contributed $138.7 million to a fund that will serve to defease the long-term asset retirement obligation for its thermal asset base; this amount is recorded as “Fund for asset retirement obligations” on the Condensed Consolidated Balance Sheets. The funds are invested in highly rated securities, such as U.S. Treasuries, which fall within Level 1 of the fair value hierarchy. The funds will only be utilized for final mine closure reclamation activities.

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

Fair Value of Long-Term Debt

At June 30, 2023 and December 31, 2022, the fair value of the Company’s debt, including amounts classified as current, was $137.7 million and $223.0 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.

11. Earnings per Common Share

The Company computes basic net income per share using the weighted average number of common shares outstanding during the period. Diluted net income 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, and convertible debt. The dilutive effect of outstanding warrants and restricted stock units is reflected in diluted earnings per share by application of the treasury stock method whereas the Convertible Debt uses the if converted method.

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

Workers' Compensation Expense

12. 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 its 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.

On January 18, 2023, the OWCP proposed revisions to regulations under the Black Lung Benefits Act governing authorization of self-insurers. The revisions seek to codify the practice of basing a self-insured operator’s security requirement on an actuarial assessment of its total present and future black lung liability. A material change to the regulations is the requirement that all self-insured operators must post security equal to 120% of their projected black lung liabilities.

The proposed regulations were posted to the Federal Register on January 19, 2023 with written comments to be accepted within 60 days of this date. Subsequently, the comment period was extended an additional 30 days.

If the above regulation is codified into law, the Company will be required to post additional collateral to maintain its self-insured status. The Company is evaluating alternatives to self-insurance, including the purchase of commercial insurance to cover these claims. Additionally, the Company is assessing the availability of surety bond capacity within the markets, additional sources of liquidity, and other items to satisfy the proposed regulations.

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 June 30,				Six Months Ended June 30,

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.

The Company is a party to numerous 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.

In the normal course of business, the Company is a party to certain financial instruments with off-balance sheet risk, such as bank letters of credit, performance or surety bonds, and other guarantees and indemnities related to the obligations of affiliated entities which are not reflected in the Company’s Condensed Consolidated Balance Sheets. However, the underlying liabilities that they secure, such as asset retirement obligations, workers’ compensation liabilities, and other obligations, are reflected in the Company’s Condensed Consolidated Balance Sheets.

As of June 30, 2023, the Company had outstanding surety bonds with a face amount of $553.0 million to secure various obligations and commitments and $74.4 million of letters of credit under its Securitization and Inventory Facilities used to collateralize certain obligations. The Company had posted $5.6 million in cash collateral related to various obligations; this amount is recorded within “Other noncurrent assets” on the Condensed Consolidated Balance Sheets.

As of June 30, 2023, the Company’s reclamation-related obligations of $243.2 million were supported by surety bonds of $456.1 million. The Company has posted $0.6 million in cash collateral related to reclamation surety bonds. This amount is recorded within “Other noncurrent assets” on the Condensed Consolidated Balance Sheets. Additionally, in the second quarter of 2023, the Company contributed an additional $1.6 million representing interest earned to a fund that will serve to defease the long-term asset retirement obligation for its thermal asset base bringing the total to $138.7 million as of June 30, 2023. This amount is recorded as “Fund for asset retirement obligations” on the Condensed Consolidated Balance Sheets.

15. 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 and coal quality, 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, divided by segment tons sold), 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, income 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: Metallurgical (MET) segment, containing the Company’s metallurgical operations in West Virginia, and the Thermal segment containing the Company’s thermal operations in Wyoming and Colorado.

Reporting segment results for the three and six months ended June 30, 2023 and 2022 are presented below. The Corporate, Other, and Eliminations grouping includes these charges: idle operations; change in fair value of coal derivatives, net; corporate overhead; land management activities; other support functions; and the elimination of intercompany transactions.

ASC 606-10-50-5 requires that entities disclose disaggregated revenue information in categories (such as type of goods or services, 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 with 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 an index-based pricing mechanism.

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 four 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 “right-of-use” (“ROU”) assets and lease liabilities using its secured incremental borrowing rate at the lease commencement date.
