FORWARD-LOOKING STATEMENTS

This Quarterly Report on Form 10-Q (this "Form 10-Q" or "this report") includes statements of our expectations, intentions, plans and beliefs that constitute “forward-looking statements” within the meaning of Section 27A of the Securities Act of 1933, as amended (the “Securities Act”) and Section 21E of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and are intended to come within the safe harbor protection provided by those sections. These statements, which involve risks and uncertainties, relate to analyses and other information that are based on forecasts of future results and estimates of amounts not yet determinable and may also relate to our future prospects, developments and business strategies, including any potential changes to our production and sales volumes as a result of our negotiations with the labor union representing certain of our hourly employees. We have used the words “anticipate,” “approximately,” “assume,” “believe,” “could,” “contemplate,” “continue,” “estimate,” “expect,” “target,” “future,” “intend,” “may,” “plan,” “potential,” “predict,” “project,” “should” and similar terms and phrases, including in references to assumptions, in this report to identify forward-looking statements. These forward-looking statements are made based on expectations and beliefs concerning future events affecting us and are subject to uncertainties and factors relating to our operations and business environment, all of which are difficult to predict and many of which are beyond our control, that could cause our actual results to differ materially from those matters expressed in or implied by these forward-looking statements. These risks and uncertainties include, but are not limited to:

•the impact of global pandemics, such as the novel coronavirus (“COVID-19”) pandemic, including the impact of any such pandemic on our business, employees, suppliers and customers, the metallurgical ("met") coal and steel industries, and global economic markets;

•the impacts of inflation on our business, including on our costs and our profitability;

•our relationships with, and other conditions affecting, our customers;

•successful implementation of our business strategies;

•unavailability of, or price increases in, the transportation of our met coal;

•significant cost increases and fluctuations, and delay in the delivery of raw materials, mining equipment and purchased components;

•work stoppages, negotiation of labor contracts, employee relations and workforce availability;

•competition and foreign currency fluctuations;

•litigation, including claims not yet asserted;

•terrorist attacks or security threats, including cybersecurity threats;

•global steel demand and the downstream impact on met coal prices;

•impact of weather and natural disasters on demand and production;

•a substantial or extended decline in pricing or demand for met coal;

•inherent difficulties and challenges in the coal mining industry that are beyond our control;

•our ability to develop or acquire met coal reserves in an economically feasible manner;

•geologic, equipment, permitting, site access, operational risks and new technologies related to mining;

•inaccuracies in our estimates of our met coal reserves;

•costs associated with our workers’ compensation benefits;

•challenges to our licenses, permits and other authorizations;

•challenges associated with environmental, health and safety laws and regulations;

•regulatory requirements associated with federal, state and local regulatory agencies, and such agencies’ authority to order temporary or permanent closure of our mines;

•climate change concerns and our operations’ impact on the environment;

•failure to obtain or renew surety bonds on acceptable terms, which could affect our ability to secure reclamation and coal lease obligations;

•our obligations surrounding reclamation and mine closure;

•our substantial indebtedness and debt service requirements;

•our ability to comply with covenants in our ABL Facility (as defined below) and the Indenture (as defined below);

•our ability to maintain adequate liquidity and the cost, availability and access to capital and financial markets;

•our expectations regarding our future cash tax rate as well as our ability to effectively utilize our net operating loss carry forwards (“NOLs”);

•our ability to continue paying our quarterly dividend or pay any special dividend;

•the timing and amount of any stock repurchases we make under our New Stock Repurchase Program (as defined below) or otherwise;

1

•any consequences related to our transfer restrictions under our certificate of incorporation and our NOL rights agreement;

•geopolitical events, including the effects of the Russia-Ukraine war and the ongoing conflict in the Middle East; and

•the inability to transport our products to customers due to rail performance issues or the impact of weather and mechanical failures at the McDuffie Terminal at the Port of Mobile in Alabama.

These forward-looking statements involve a number of risks and uncertainties that could cause actual results to differ materially from those suggested by the forward-looking statements. Forward-looking statements should, therefore, be considered in light of various factors, including those set forth under “Part II, Item 1A. Risk Factors,” “Part I, Item 2. Management's Discussion and Analysis of Financial Condition and Results of Operations” and elsewhere in this Form 10-Q, and those set forth from time to time in our other filings with the Securities and Exchange Commission (the “SEC”). These documents are available through our website at www.warriormetcoal.com or through the SEC's Electronic Data Gathering and Analysis Retrieval system at http://www.sec.gov. In light of such risks and uncertainties, we caution you not to place undue reliance on these forward-looking statements.

When considering forward-looking statements made by us in this Form 10-Q, or elsewhere, such statements speak only as of the date on which we make them. New risks and uncertainties arise from time to time, and it is impossible for us to predict these events or how they may affect us. We have no duty to, and do not intend to, update or revise the forward-looking statements in this Form 10-Q after the date of this Form 10-Q, except as may be required by law. In light of these risks and uncertainties, you should keep in mind that any forward-looking statement made in this Form 10-Q or elsewhere might not occur.

NOTES TO CONDENSED FINANCIAL STATEMENTS

NINE MONTHS ENDED SEPTEMBER 30, 2023 (UNAUDITED)

Note 1. Business and Basis of Presentation

Description of the Business

Warrior Met Coal, Inc. (the "Company") is a U.S.-based environmentally and socially minded supplier to the global steel industry. The Company is dedicated entirely to mining non-thermal met coal used as a critical component of steel production by metal manufacturers in Europe, South America and Asia. The Company is a large-scale, low-cost producer and exporter of premium met coal, also known as hard-coking coal ("HCC"), operating highly efficient longwall operations in its underground mines based in Alabama. The HCC that the Company produces from the Blue Creek coal seam contains very low sulfur, has strong coking properties and is of a similar quality to coal referred to as premium HCC produced in Australia. The Company also generates ancillary revenues from the sale of natural gas extracted as a byproduct from the underground coal mines and royalty revenues from leased properties.

Basis of Presentation

The accompanying financial statements are presented in accordance with accounting principles generally accepted in the United States (“GAAP”) for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements. In our opinion, the financial statements include all adjustments (consisting of normal recurring accruals) necessary in order to make the financial statements not misleading. For further information, refer to the financial statements and related notes included in the Company's Annual Report on Form 10-K for the year ended December 31, 2022 (the "2022 Annual Report"). Operating results for the three and nine months ended September 30, 2023 are not necessarily indicative of the final results that may be expected for the year ended December 31, 2023. The balance sheet at December 31, 2022 has been derived from the audited financial statements for the year ended December 31, 2022 included in the 2022 Annual Report.

Collective Bargaining Agreement

The Company's Collective Bargaining Agreement ("CBA") with the labor union representing certain of the Company's hourly employees expired on April 1, 2021 and the labor union initiated a strike after an agreement on a new contract was not reached. As a result of the strike, the Company initially idled Mine No. 4 and scaled back operations at Mine No. 7. In the first quarter of 2022, the Company restarted operations at Mine No. 4. Due to the reduced operations at Mine No. 4 and Mine No. 7, the Company incurred idle mine expenses of $5.4 million and $10.1 million for the three and nine months ended September 30, 2022. The Company incurred no idle mine expenses for the three and nine months ended September 30, 2023. These expenses are reported separately in the Condensed Statements of Operations and represent expenses incurred, such as electricity, insurance and maintenance labor. The Company incurred business interruption expenses of approximately $0.3 million and $8.1 million for the three and nine months ended September 30, 2023, which represent ongoing legal expenses associated with ongoing labor negotiations. The Company incurred $7.1 million and $20.1 million for the three and nine months ended September 30, 2022, which represent non-recurring expenses that were directly attributable to the labor strike for incremental safety and security, labor negotiations and other expenses. These expenses are also presented separately in the Condensed Statements of Operations. On February 16, 2023, the labor union representing certain of the Company's hourly employees announced that they were ending the strike and made an unconditional offer to return to work. The return-to-work process for eligible employees who wished to return to work which began in February and has been completed. The Company continues to engage in good faith efforts with the labor union to reach an agreement on a new contract.

Acquisitions

On March 31, 2023, the Company acquired the remaining ownership interest in gas wells owned by an independent third party for $2.4 million. The purchase consideration has been preliminarily allocated to the assets acquired and liabilities assumed based upon their estimated fair values at the date of acquisition. A full and detailed valuation of the assets and liabilities is being completed. Accordingly, the allocation is preliminary and may change as additional information becomes available and is assessed by the Company. The final allocation of the consideration transferred may include adjustments to the fair value estimates of identifiable assets and liabilities after a full review has been completed. The acquisition is not deemed to be material to the condensed financial statements.

On March 1, 2022, the Company acquired the remaining 50% interest in Black Warrior Methane ("BWM") and Black Warrior Transmission ("BWT") for $0.3 million. The purchase consideration has been allocated to the assets acquired and

WARRIOR MET COAL, INC.

NOTES TO CONDENSED FINANCIAL STATEMENTS (Continued)

NINE MONTHS ENDED SEPTEMBER 30, 2023 (UNAUDITED)

liabilities assumed based upon their estimated fair values at the date of acquisition. The acquisition is not deemed to be material to the condensed financial statements.

Note 2. Summary of Significant Accounting Policies

The Company's significant accounting policies are consistent with those disclosed in Note 2 to its audited financial statements included in the 2022 Annual Report.

Cash and Cash Equivalents

Cash and cash equivalents include short-term deposits and highly liquid investments that have original maturities of three months or less when purchased and are stated at cost, which approximates fair value.

Short-Term Investments

Instruments with maturities greater than three months, but less than twelve months, are included in short-term investments. The Company also purchases fixed income securities and certificates of deposits with varying maturities that are classified as available for sale and are carried at fair value. Securities classified as held to maturity are those securities that management has the intent and ability to hold to maturity.

As of September 30, 2023 and December 31, 2022, short-term investments consisted of $8.9 million and $8.6 million in cash and fixed income securities. The short-term investments are posted as collateral for the self-insured black lung related claims asserted by or on behalf of former employees of Walter Energy, Inc. ("Walter Energy") and its subsidiaries, which were assumed by the Company and relate to periods prior to March 31, 2016.

Revenue Recognition

    Revenue is recognized when performance obligations under the terms of a contract with the Company's customers are satisfied; for all contracts this occurs when control of the promised goods has been transferred to its customers. For coal shipments to domestic customers via rail, control is transferred when the railcar is loaded. For coal shipments to international customers via ocean vessel, control is transferred when the vessel is loaded at the Port of Mobile, Alabama. For natural gas sales, control is transferred when the gas has been transferred to the pipeline. Revenue is disaggregated between coal sales within the Company's mining segment and natural gas sales which is included in all other revenues, as disclosed in Note 13.

Since February 2017, the Company has had an arrangement with XCoal Energy & Resources ("XCoal") to serve as XCoal's strategic partner for exports of low-volatility HCC typically to the Asian region. Under this arrangement, XCoal takes title to and markets coal that the Company would historically have sold on the spot market, in an amount of the greater of (i) 10% of the Company's total production during the applicable term of the arrangement or (ii) 250,000 metric tons. During the three and nine months ended September 30, 2023 and 2022, XCoal accounted for approximately $36.7 million, or 7.3% and $126.8 million or 9.8% of total sales, and $69.8 million, or 20.6% and $281.3 million or 20.7% of total sales, respectively.

Trade Accounts Receivable and Allowance for Credit Losses

    Trade accounts receivable represent customer obligations that are derived from revenue recognized from contracts with customers. Credit is extended based on an evaluation of the individual customer's financial condition. The Company maintains trade credit insurance on the majority of its customers and the geographic regions of coal shipments to these customers. In some instances, the Company requires letters of credit, cash collateral or prepayments from its customers on or before shipment to mitigate the risk of loss. These efforts have consistently resulted in the Company recognizing no historical credit losses. The Company also has never had to have a claim against its trade credit insurance policy.

In order to estimate the allowance for credit losses on trade accounts receivable, the Company utilizes an aging approach in which potential impairment is calculated based on how long a receivable has been outstanding (e.g., current, 1-31 days, 31-60 days, etc.). The Company calculates an expected credit loss rate based on the Company’s historical credit loss rate, the risk characteristics of our customers, and the current met coal and steel market environments. As of September 30, 2023 and December 31, 2022, the estimated allowance for credit losses was immaterial and did not have a material impact on the Company's financial statements.

Note 4. Income Taxes

For the three and nine months ended September 30, 2023 and 2022, the Company estimated its annual effective tax rate and applied this effective tax rate to its year-to-date pretax income at the end of the interim reporting period. The tax effect of unusual or infrequently occurring items, including the effects of changes in tax laws or rates and changes in judgment about the realizability of deferred tax assets, are reported in the interim period in which they occur. For the three and nine months ended September 30, 2023, the Company had income tax expense of $16.8 million and $60.4 million, respectively.

The $16.8 million and $60.4 million income tax expense for the three and nine months ended September 30, 2023, includes a benefit related to depletion and Internal Revenue Code ("IRC") Section 250 Deduction: Foreign-Derived Intangible Income ("FDII"). The Tax Cuts and Jobs Act ("TCJA") was enacted on December 22, 2017 and enacted IRC Section 250 Deduction: FDII, which provides for, among other things, a deduction of 37.5% with respect to foreign-derived intangible income, which reduces the statutory tax rate from 21% to 13.125%. Beginning in 2026, the deduction is reduced from 37.5% to 22.5% of foreign-derived intangible income. The Company has historically not been eligible to claim the deduction due to the deduction being limited to taxable income and the Company's ability to utilize its net operating losses to offset taxable income.

Senior Secured Notes

On December 6, 2021, the Company issued $350.0 million in aggregate principal amount of 7.875% senior secured notes due 2028 (the “Notes”) at an initial price of 99.343% of their face amount. The Notes were issued to qualified institutional buyers pursuant to Rule 144A under the Securities Act of 1933, as amended (the “Securities Act”), and to certain non-U.S. persons in transactions outside the United States in accordance with Regulation S under the Securities Act. The Company used the net proceeds of the offering of the Notes, together with cash on hand, to fund the redemption of all of the Company’s outstanding 8.00% senior secured notes due 2024 (the “Existing Notes”), including payment of the redemption premium in connection with such redemption. The Notes will mature on December 1, 2028.

During the nine months ended September 30, 2023, the Company repurchased in the open market and extinguished approximately $8.0 million principal amount of our Notes. In connection with the extinguishment of our Notes, we recognized a loss on early extinguishment of debt of $0.1 million which is included in interest income (expense), net in the Condensed Statements of Operations.

Offers to Purchase the Notes

On August 9, 2023, the Company commenced an offer to purchase (the “Restricted Payment Offer”), in cash, up to $150,000,000 principal amount of its outstanding Notes, at a repurchase price of 103% of the aggregate principal amount of such Notes, plus accrued and unpaid interest with respect to such Notes to, but not including, the date of repurchase (the “Restricted Payment Repurchase Price”). Concurrently with, but separate from, the Restricted Payment Offer, the Company commenced a cash tender offer (the “Tender Offer” and, together with the Restricted Payment Offer, the “Offers”) to purchase up to $150,000,000 principal amount of the Notes at a repurchase price of 104.25% of the aggregate principal amount of such Notes, plus accrued and unpaid interest to, but not including, the date of repurchase (the “TO Repurchase Price”). The Offers expired on September 7, 2023 (the “Expiration Date”).

Restricted Payment Offer

As of the Expiration Date, $200,000 aggregate principal amount of the Notes were validly tendered and not validly withdrawn pursuant to the Restricted Payment Offer. Pursuant to the terms of the Restricted Payment Offer:

(1) an automatic pro ration factor of 49.5674% was applied to the $200,000 aggregate principal amount of the Notes that were validly tendered and not validly withdrawn in the Restricted Payment Offer (rounded down to avoid the purchase of Notes in a principal amount other than in integrals of $1,000), which resulted in $99,000 aggregate principal amount of the Notes (the “RP Pro-Rated Tendered Notes”);

(2) the Company accepted all $99,000 aggregate principal amount of the RP Pro-Rated Tendered Notes for payment of the Restricted Payment Repurchase Price in cash; and

(3) the remaining balance of $101,000 aggregate principal amount of the Notes tendered that were not RP Pro-Rated Tendered Notes were not accepted for payment and were returned to the tendering holder of the Notes.

The Company consummated the Restricted Payment Offer on September 8, 2023.

Accordingly, pursuant to the terms of the Indenture, the Company will have the ability from time to time in the future to make one or more restricted payments (the "Proposed Restricted Payment") in the form of special dividends to holders of the Company’s common stock and/or repurchases of the Company’s common stock in the aggregate amount of up to $299,901,000 consistent with the terms of the Capital Allocation Policy adopted by the Company's board of directors (the "Board"). Any future Proposed Restricted Payments will be at the discretion of the Board and subject to a number of factors and there can be no assurance that the Company will make any Proposed Restricted Payments in the future.

Tender Offer

As of the Expiration Date, $294,770,000 aggregate principal amount of the Notes were validly tendered and not validly withdrawn pursuant to the Tender Offer. Pursuant to the terms of the Tender Offer:

(1) an automatic pro ration factor of 49.5674% was applied to the $294,770,000 aggregate principal amount of the Notes that were validly tendered and not validly withdrawn in the Tender Offer (rounded down to avoid the purchase of Notes in a principal amount other than in integrals of $1,000), which resulted in $146,002,000 aggregate principal amount of the Notes (the “TO Pro-Rated Tendered Notes”);

(2) the Company accepted all $146,002,000 aggregate principal amount of the TO Pro-Rated Tendered Notes for payment of the TO Repurchase Price in cash; and

(3) the remaining balance of $148,768,000 aggregate principal amount of the Notes tendered that were not TO Pro-Rated Tendered Notes were not accepted for payment and were returned to the tendering holder of the Notes.

The Company consummated the Tender Offer on September 11, 2023.

In connection with the payments for the RP Pro-Rated Tendered Notes and the TO Pro-Rated Tendered Notes, the Company recognized a loss on early extinguishment of debt of $11.7 million during the three and nine months ended September 30, 2023.

ABL Facility

On December 6, 2021, the Company entered into the Second Amended and Restated Asset-Based Revolving Credit Agreement (the “Second Amended and Restated Credit Agreement”), by and among the Company and certain of its subsidiaries, as borrowers, the guarantors party thereto, the lenders from time to time party thereto and Citibank, as administrative agent (in such capacity, the "Agent"), which amends and restates in its entirety the then existing Amended and Restated Asset-Based Revolving Credit Agreement (as amended, the “ABL Facility”). The Second Amended and Restated Credit Agreement, among other things, (i) extended the maturity date of the ABL Facility to December 6, 2026; (ii) changed the calculation of the interest rate payable on borrowings from being based on a London Inter-Bank Offered Rate to be based on a SOFR, with corresponding changes to the applicable interest rate margins with respect to such borrowings, (iii) amended certain definitions related to the calculation of the borrowing base; (iv) increased the commitments that may be used to issue letters of credit to $65.0 million; and (v) amended certain baskets contained in the covenants to conform to the baskets contained in the indenture governing the Notes (the "Indenture"). The Second Amended and Restated Credit Agreement also allows the Company to borrow up to $132.0 million through October 13, 2023, decreasing to $116.0 million through November 2026, subject to availability under the borrowing base and other conditions.

As of September 30, 2023, no loans were outstanding under the ABL Facility and there were $8.7 million of letters of credit issued and outstanding under the ABL Facility. At September 30, 2023, the Company had $123.3 million of availability under the ABL Facility (calculated net of $8.7 million of letters of credit outstanding at such time).

Note 9. Commitments and Contingencies

Environmental Matters

The Company is subject to a wide variety of laws and regulations concerning the protection of the environment, both with respect to the construction and operation of its plants, mines and other facilities and with respect to remediating environmental conditions that may exist at its own and other properties.

The Company believes it is in compliance with federal, state and local environmental laws and regulations. The Company accrues for environmental expenses resulting from existing conditions that relate to past operations when the costs are probable and can be reasonably estimated. As of September 30, 2023 and December 31, 2022, there were no accruals for environmental matters other than asset retirement obligations for mine reclamation.

Miscellaneous Litigation

From time to time, the Company is party to lawsuits arising in the ordinary course of business. The Company records costs relating to these matters when a loss is probable and the amount can be reasonably estimated. The effect of the outcome of these matters on the Company’s future results of operations cannot be predicted with certainty as any such effect depends on future results of operations and the amount and timing of the resolution of such matters. As of September 30, 2023 and December 31, 2022, there were no items accrued for miscellaneous litigation.

On July 15, 2015, Walter Energy and certain of its wholly owned U.S. subsidiaries, including Jim Walter Resources, Inc. (“JWR”) filed voluntary petitions for relief under chapter 11 of title 11 of the U.S. Bankruptcy Code (the “Chapter 11 Cases”) in the Northern District of Alabama, Southern Division. On December 7, 2015, Walter Energy Canada Holdings, Inc., Walter Canadian Coal Partnership and their Canadian affiliates (collectively “Walter Canada”) applied for and were granted protection under the Companies’ Creditors Arrangement Act (the “CCAA”) pursuant to an Initial Order of the Supreme Court of British Columbia. As a result of the Company’s acquisition of certain core operating assets of Walter Energy during the Chapter 11 Cases, in the first quarter of 2023 and 2022 the Company received $0.2 million and $0.7 million, respectively, from the Chapter 11 Cases which is reflected as other income in the Condensed Statement of Operations.

Other Commitments and Contingencies

The Company is party to various transportation and throughput agreements with rail and barge transportation providers and the Alabama State Port Authority. These agreements contain annual minimum tonnage guarantees with respect to coal transported from the mine sites to the Port of Mobile, Alabama, the unloading of rail cars or barges, and the loading of vessels. If the Company does not meet its minimum throughput obligations, which are based on annual minimum amounts, it is required to pay the transportation providers or the Alabama State Port Authority a contractually specified amount per metric ton for the difference between the actual throughput and the minimum throughput requirement. At September 30, 2023 and December 31, 2022, the Company had no liability recorded for minimum throughput requirements.

Royalty Obligations

A substantial amount of the coal that the Company mines is produced from mineral reserves leased from third-party landowners. These leases convey mining rights to the Company in exchange for royalties to be paid to the landowner as either a fixed amount per ton or as a percentage of the sales price. Although coal leases have varying renewal terms and conditions, they generally last for the economic life of the reserves. Coal royalty expenses were $29.3 million and $94.0 million and $42.4 million and $116.3 million for the three and nine months ended September 30, 2023 and 2022, respectively.

Note 10. Stockholders' Equity

Common Shares

The Company is authorized to issue up to 140,000,000 common shares, $0.01 par value per share. Holders of common shares are entitled to receive dividends when authorized by the Board.

Stock Repurchase Program

On March 26, 2019, the Board approved the Company's second stock repurchase program (the “New Stock Repurchase Program”) that authorizes repurchases of up to an aggregate of $70.0 million of the Company's outstanding common stock. The Company fully exhausted its previous stock repurchase program (the "First Stock Repurchase Program") of $40.0 million of its outstanding common stock. The New Stock Repurchase Program does not require the Company to repurchase a specific number of shares or have an expiration date. The New Stock Repurchase Program may be suspended or discontinued by the Board at any time without prior notice.

    Under the New Stock Repurchase Program, the Company may repurchase shares of its common stock from time to time, in amounts, at prices and at such times as the Company deems appropriate, subject to market and industry conditions, share price, regulatory requirements and other considerations as determined from time to time by the Company. The Company’s repurchases may be executed using open market purchases or privately negotiated transactions in accordance with applicable securities laws and regulations, including Rule 10b-18 of the Exchange Act and repurchases may be executed pursuant to Rule 10b5-1 under the Exchange Act. Repurchases will be subject to limitations in the ABL Facility and the Indenture. The Company intends to fund repurchases under the New Stock Repurchase Program from cash on hand and/or other sources of liquidity. Any future repurchases of shares of the Company's common stock will be subject to the 1% excise tax under the Inflation Reduction Act of 2022 (“IRA”).

As of September 30, 2023 and December 31, 2022, the Company has repurchased 500,000 shares under the New Stock Repurchase Program for approximately $10.6 million, leaving approximately $59.4 million of share repurchases authorized under the New Stock Repurchase Program.

Preferred Shares

The Company is authorized to issue up to 10,000,000 shares of preferred stock, $0.01 par value per share.

Note 11. Derivative Instruments

The Company enters into natural gas swap contracts from time to time to hedge the exposure to variability in expected future cash flows associated with the fluctuations in the price of natural gas related to the Company’s forecasted sales. As of September 30, 2023 and December 31, 2022, the Company had no natural gas swap contracts outstanding.

The Company’s natural gas swap contracts economically hedge certain risks but are not designated as hedges for financial reporting purposes. All changes in the fair value of these derivative instruments are recorded as other revenues in the Condensed Statements of Operations. The Company recognized a gain related to natural gas swap contracts of $1.2 million, for the nine months ended September 30, 2023. The Company recognized no losses for the three months ended September 30, 2023 and September 30, 2022 and recognized $27.7 million for the nine months ended September 30, 2022. The Company records all derivative instruments at fair value and had no asset or liability recorded as of September 30, 2023 and December 31, 2022.

Note 12. Fair Value of Financial Instruments

The Company had no significant assets or any other liabilities measured at fair value on a recurring basis as of September 30, 2023 or December 31, 2022. During the nine months ended September 30, 2023, there were no transfers between Level 1, Level 2 and Level 3. The Company uses quoted dealer prices for similar contracts in active over-the-counter markets for determining fair value of Level 2 liabilities. There were no changes to the valuation techniques used to measure liability fair values on a recurring basis during the nine months ended September 30, 2023.

The following methods and assumptions were used to estimate the fair value for which the fair value option was not elected:

Cash and cash equivalents, short-term investments, receivables and trade accounts payable — The carrying amounts reported in the Condensed Balance Sheets approximate fair value due to the short-term nature of these assets and liabilities.

Debt — The Company's outstanding debt is carried at cost. As of September 30, 2023, there were no borrowings outstanding under the ABL Facility, with $123.3 million available, net of outstanding letters of credit of $8.7 million. As of December 31, 2022, the Company had no borrowings outstanding under the ABL Facility, with $123.3 million available, net of outstanding letters of credit of $8.7 million. As of September 30, 2023 and December 31, 2022, the estimated fair value of the Notes based upon observable market data (Level 2) was approximately $156.9 million and $304.4 million, respectively.

Note 13. Segment Information

The Company identifies a business as an operating segment if: (i) it engages in business activities from which it may earn revenues and incur expenses; (ii) its operating results are regularly reviewed by the Chief Operating Decision Maker (“CODM”), who is the Company’s Chief Executive Officer, to make decisions about resources to be allocated to the segment and assess its performance; and (iii) it has available discrete financial information. The Company has determined that its two underground mining operations are its operating segments. The CODM reviews financial information at the operating segment level to allocate resources and to assess the operating results and financial performance for each operating segment. Operating segments are aggregated into a reportable segment if the operating segments have similar quantitative economic characteristics and if the operating segments are similar in the following qualitative characteristics: (i) nature of products and services; (ii) nature of production processes; (iii) type or class of customer for their products and services; (iv) methods used to distribute the products or provide services; and (v) if applicable, the nature of the regulatory environment.

The Company has determined that the two operating segments are similar in both quantitative and qualitative characteristics and thus the two operating segments have been aggregated into one reportable segment. The Company has determined that its natural gas and royalty businesses and the Blue Creek mine development did not meet the criteria in ASC 280 to be considered as operating or reportable segments. Therefore, the Company has included their results in an “all other” category as a reconciling item to consolidated amounts.

The Company does not allocate all of its assets, or its depreciation and depletion expense, selling, general and administrative expenses, transactions costs, interest income (expense), and income tax expense or benefit by segment.

The following tables include reconciliations of segment information to consolidated amounts (in thousands):

Total capital expenditures	$	106,525	$	41,320	$	310,820	$	120,022

The Company evaluates the performance of its segment based on Segment Adjusted EBITDA, which is defined as net income adjusted for other revenues, cost of other revenues, depreciation and depletion, selling, general and administrative, business interruption, idle mine, other income, interest income (expense), net, income tax expense, loss on extinguishment of debt and certain transactions or adjustments that the CODM does not consider for the purposes of making decisions to allocate resources among segments or assessing segment performance. Segment Adjusted EBITDA does not represent and should not be considered as an alternative to cost of sales under GAAP and may not be comparable to other similarly titled measures used by other companies. Below is a reconciliation of Segment Adjusted EBITDA to net income, which is its most directly comparable financial measure calculated and presented in accordance with GAAP (in thousands):

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

The following discussion and analysis provides a narrative of our results of operations and financial condition for the three and nine months ended September 30, 2023 and September 30, 2022. You should read the following discussion and analysis of our financial condition and results of operations together with our financial statements and related notes appearing in this Form 10-Q and the audited financial statements for the year ended December 31, 2022 included in our Annual Report on Form 10-K for the year ended December 31, 2022 (the "2022 Annual Report"). Some of the information contained in this discussion and analysis or set forth elsewhere in this Form 10-Q, including information with respect to our plans and strategy for our business and related financing, includes forward-looking statements that involve risks and uncertainties. As a result of many factors, our actual results could differ materially from the results described in, or implied by, the forward-looking statements contained in the following discussion and analysis. Please see “Forward-Looking Statements.”

Overview

We are a U.S.-based, environmentally and socially minded supplier to the global steel industry. We are dedicated entirely to mining non-thermal metallurgical ("met") coal used as a critical component of steel production by metal manufacturers in Europe, South America and Asia. We are a large-scale, low-cost producer and exporter of premium met coal, also known as hard coking coal (“HCC”) or steelmaking coal, operating highly-efficient longwall operations in our underground mines based in Alabama, Mine No. 4 and Mine No. 7.

As of December 31, 2022, based on a reserve report prepared by Marshall Miller & Associates, Inc. ("Marshall Miller"), Mine No. 4 and Mine No. 7, our two operating mines, had approximately 89.0 million metric tons of recoverable reserves and our undeveloped Blue Creek mine contained 68.2 million metric tons of recoverable reserves and 39.2 million metric tons of coal resources exclusive of reserves, which total 107.4 million metric tons. As a result of our high-quality coal, our realized price has historically been in line with, or at a slight discount to, the Platts Premium Low Volatility ("LV") Free On Board ("FOB") Australia Index Price ("Platts Index"). Our HCC, mined from the Southern Appalachian portion of the Blue Creek coal seam, is characterized by low sulfur, low-to-medium ash, and LV to mid-volatility ("MV"). These qualities make our coal ideally suited as a coking coal for the manufacture of steel. As mining of the reserves in Mine No. 4 advances to the north area of the mine, we expect that the quality of the coal from Mine No. 4 will transition from an LV to MV to a High Vol A quality coal. High Vol A coals have traditionally priced at a slight discount to the Australian premium LV and the U.S. LV coals; however, in recent years we have observed extended periods during which High Vol A coals priced at a premium over these coals. We expect High Vol A coals will continue to become increasingly scarce as a result of Central Appalachian producers mining thinner and deeper reserves, which is expected to continue to support prices.

We sell substantially all of our steelmaking coal production to steel producers. Steelmaking coal, which is converted to coke, is a critical input in the steel production process. Steelmaking coal is both consumed domestically in the countries where it is produced and exported by several of the largest producing countries, such as China, Australia, the United States, Canada and Russia. Therefore, demand for our coal will be highly correlated to conditions in the global steelmaking industry. The steelmaking industry’s demand for steelmaking coal is affected by a number of factors, including the cyclical nature of that industry’s business, technological developments in the steelmaking process and the availability of substitutes for steel such as aluminum, composites and plastics. A significant reduction in the demand for steel products would reduce the demand for steelmaking coal, which would have a material adverse effect upon our business. Similarly, if alternative ingredients are used in substitution for steelmaking coal in the integrated steel mill process, the demand for steelmaking coal would materially decrease, which could also materially adversely affect demand for our steelmaking coal.

Recent Developments

U.S. inflation remains at 3.7%, driven by increased energy and food costs, supply constraints and strong consumer demand. High inflation has been driven by growth in the economy as it bounces back from the novel coronavirus ("COVID-19"), powered in part by low interest rates and government stimulus to counter the pandemic's impact. While we expect inflation to continue to ease in the overall economy for the remainder of 2023, we have not seen it easing in the coal mining industry and expect that inflation will continue to negatively impact our profitability, as we expect inflation to remain high for steel prices, freight rates, labor and other materials and supplies. Inflation affects, among others, the costs of belt structure, roof bolts, cable, magnetite, rock dust and other supplies, plus labor and parts on equipment repair and rebuilds.

The global seaborne metallurgical coal market improved during the third quarter of 2023, primarily driven by tight supply from Australia due to disruptions at Queensland ports combined with many Australian producers being shut down due to maintenance programs, production issues, labor related constraints and logistical transportation issues. All major met coal price indices ended the quarter at their highs, while the Platts Index experienced the largest increase of all the indices. According to

19

the World Steel Association monthly report, the positive growth in steel production in the current year was mainly driven by higher Chinese steel production, which grew by 3.7% through the first eight months of this year compared to the prior year. India's steel production, increased 7.6% for the same period. Most other steel producing regions of the world experienced production declines year over year. Overall seaborne export demand is expected to remain stable for the remainder of the year, but the evolving conflict in the Middle East and the uncertainty surrounding the global economy are likely to impact the supply and demand for steelmaking coal.

Collective Bargaining Agreement

Our Collective Bargaining Agreement ("CBA") with the labor union representing certain of our hourly employees expired on April 1, 2021 and the labor union initiated a strike after an agreement on a new contract was not reached. As a result of the strike, we initially idled Mine No. 4 and scaled back operations at Mine No. 7. In the first quarter of 2022, we restarted operations at Mine No. 4. Due to the reduced operations at Mine No. 4 and Mine No. 7, we incurred idle mine expenses of $5.4 million and $10.1 million for the three and nine months ended September 30, 2022. The Company incurred no idle mine expenses for the three and nine months ended September 30, 2023. These expenses are reported separately in the Condensed Statements of Operations and represent expenses incurred, such as electricity, insurance and maintenance labor. We have also incurred business interruption expenses of approximately $0.3 million and $8.1 million for the three and nine months ended September 30, 2023 and $7.1 million and $20.1 million for the three and nine months ended September 30, 2022, which represent non-recurring expenses that are directly attributable to the labor strike for incremental safety and security, labor negotiations and other expenses. These expenses are also presented separately in the Condensed Statements of Operations. On February 16, 2023, the labor union representing certain of our hourly employees announced that they were ending the strike and made an unconditional offer to return to work. The return-to-work process for eligible employees who wished to return to work began in February and has been completed. We continue to engage in good faith efforts with the labor union to reach an agreement on a new contract.

Acquisitions

On March 1, 2022, we acquired the remaining 50% interest in Black Warrior Methane ("BWM") and Black Warrior Transmission ("BWT") for $0.3 million. The purchase consideration has been allocated to the assets acquired and liabilities assumed based upon their estimated fair values at the date of acquisition. The acquisition is not deemed to be material to the condensed financial statements.

On March 31, 2023, we acquired the remaining ownership interest in gas wells owned by an independent third party for $2.4 million. The purchase consideration has been preliminarily allocated to the assets acquired and liabilities assumed based upon their estimated fair values at the date of acquisition. A full and detailed valuation of the assets and liabilities is being completed. Accordingly, the allocation is preliminary and may change as additional information becomes available and is assessed by us. The final allocation of the consideration transferred may include adjustments to the fair value estimates of identifiable assets and liabilities, after a full review has been completed. The acquisition is not deemed to be material to the condensed financial statements.

How We Evaluate Our Operations

Our primary business, the mining and exporting of steelmaking coal for the steel industry, is conducted in one reportable business segment: mining. All other operations and results are reported under the “All Other” category as a reconciling item to consolidated amounts, which includes the business results from our sale of natural gas extracted as a byproduct from our underground coal mines and royalties from our leased properties. Our natural gas and royalty businesses do not meet the criteria in ASC 280, Segment Reporting, to be considered as operating or reportable segments.

Our management uses a variety of financial and operating metrics to analyze our performance. These metrics are significant factors in assessing our operating results and profitability and include: (i) Segment Adjusted EBITDA (as defined below), a non-GAAP financial measure; (ii) sales volumes and average net selling price, which drive coal sales revenue; (iii) cash cost of sales, a non-GAAP financial measure; and (iv) Adjusted EBITDA, a non-GAAP financial measure. The following table presents supplementary data on a historical basis for each of the periods indicated.

20

	For the three months ended September 30,				For the nine months ended September 30,
(in thousands)	2023		2022		2023		2022
Segment Adjusted EBITDA	$	156,512	$	168,503	$	564,954	$	847,796
Metric tons sold	2,048		1,360		5,429		3,782
Metric tons produced	1,808		1,490		5,149		4,397
Average net selling price per metric ton	$	203.56	$	273.49	$	237.32	$	364.27
Cash cost of sales per metric ton	$	126.36	$	148.56	$	132.49	$	139.15
Adjusted EBITDA	$	145,780	$	171,612	$	535,167	$	846,680

Segment Adjusted EBITDA

We define Segment Adjusted EBITDA as net income adjusted for other revenues, cost of other revenues, depreciation and depletion, selling, general and administrative, business interruption, idle mine expense, interest income (expense), net, income tax expense, other income, loss on early extinguishment of debt and certain transactions or adjustments that the Chief Executive Officer, our Chief Operating Decision Maker, does not consider for the purposes of making decisions to allocate resources among segments or assessing segment performance. Segment Adjusted EBITDA is used as a supplemental financial measure by management and by external users of our financial statements, such as investors, industry analysts, lenders and ratings agencies, to assess: 

•our operating performance as compared to the operating performance of other companies in the coal industry, without regard to financing methods, historical cost basis or capital structure;

•the ability of our assets to generate sufficient cash flow to pay dividends;

•our ability to incur and service debt and fund capital expenditures; and

•the viability of acquisitions and other capital expenditure projects and the returns on investment of various investment opportunities.

Sales Volumes and Average Net Selling Price

We evaluate our operations based on the volume of coal we can safely produce and sell in compliance with regulatory standards, and the prices we receive for our steelmaking coal. Our sales volume and sales prices are largely dependent upon the terms of our annual steelmaking coal sales contracts, for which prices generally are set on daily index averages. The volume of steelmaking coal we sell is also a function of the pricing environment in the international met coal markets and the amounts of LV and MV coal that we sell. We evaluate the price we receive for our steelmaking coal based on our average net selling price per metric ton.

Our average net selling price per metric ton represents our coal net sales revenue divided by total metric tons of coal sold. In addition, our average net selling price per metric ton is net of demurrage and quality specification adjustments.

Cash Cost of Sales

We evaluate our cash cost of sales on a cost per metric ton basis. Cash cost of sales is based on reported cost of sales and includes items such as freight, royalties, manpower, fuel and other similar production and sales cost items, and may be adjusted for other items that, pursuant to accounting principles generally accepted in the United States ("GAAP"), are classified in the Condensed Statements of Operations as costs other than cost of sales, but relate directly to the costs incurred to produce met coal and sell it FOB at the Port of Mobile, Alabama. Our cash cost of sales per metric ton is calculated as cash cost of sales divided by the metric tons sold. Cash cost of sales is used as a supplemental financial measure by management and by external users of our financial statements, such as investors, industry analysts, lenders and ratings agencies, to assess: 

•our operating performance as compared to the operating performance of other companies in the coal industry, without regard to financing methods, historical cost basis or capital structure; and

21

•the viability of acquisitions and other capital expenditure projects and the returns on investment of various investment opportunities.

We believe that this non-GAAP financial measure provides additional insight into our operating performance, and reflects how management analyzes our operating performance and compares that performance against other companies for purposes of business decision making by excluding the impact of certain items that management does not believe are indicative of our core operating performance. We believe that cash cost of sales presents a useful measure of our controllable costs and our operational results by including all costs incurred to produce met coal and sell it FOB at the Port of Mobile, Alabama. Period-to-period comparisons of cash cost of sales are intended to help management identify and assess additional trends that potentially impact us and that may not be shown solely by period-to-period comparisons of cost of sales. Cash cost of sales should not be considered an alternative to cost of sales or any other measure of financial performance or liquidity presented in accordance with GAAP. Cash cost of sales excludes some, but not all, items that affect cost of sales, and our presentation may vary from the presentations of other companies. As a result, cash cost of sales as presented below may not be comparable to similarly titled measures of other companies.

The following table presents a reconciliation of cash cost of sales to total cost of sales, the most directly comparable GAAP financial measure, on a historical basis for each of the periods indicated.

(in thousands)	For the three months ended September 30,				For the nine months ended September 30,
	2023		2022		2023		2022
Cost of sales (exclusive of depreciation and depletion)	$	260,376	$	203,441	$	723,458	$	529,869
Asset retirement obligation accretion	(540)		(493)		(1,619)		(1,480)
Stock compensation expense	(1,049)		(909)		(2,531)		(2,136)
Cash cost of sales	$	258,787	$	202,039	$	719,308	$	526,253

Adjusted EBITDA

We define Adjusted EBITDA as net income before interest (income) expense, net, income tax expense, depreciation and depletion, non-cash asset retirement obligation accretion, non-cash stock compensation expense, other non-cash accretion, mark-to-market (gain) loss on gas hedges, business interruption, idle mine expense, loss on extinguishment of debt and other expense (income). Adjusted EBITDA is used as a supplemental financial measure by management and by external users of our financial statements, such as investors, industry analysts, lenders and ratings agencies, to assess: 

•our operating performance as compared to the operating performance of other companies in the coal industry, without regard to financing methods, historical cost basis or capital structure; and

•the viability of acquisitions and other capital expenditure projects and the returns on investment of various investment opportunities.

We believe that the presentation of Adjusted EBITDA in this report provides information useful to investors in assessing our financial condition and results of operations. The GAAP measure most directly comparable to Adjusted EBITDA is net income. Adjusted EBITDA should not be considered an alternative to net income or any other measure of financial performance or liquidity presented in accordance with GAAP. Adjustments exclude some, but not all, items that affect net income and our presentation of Adjusted EBITDA may vary from that presented by other companies.

The following table presents a reconciliation of Adjusted EBITDA to net income, the most directly comparable GAAP financial measure, on a historical basis for each of the periods indicated.

Sales and cost of sales components on a per unit basis were as follows: 

	For the three months ended September 30,
	2023		2022
Met Coal (metric tons in thousands)
Metric tons sold	2,048		1,360
Metric tons produced	1,808		1,490
Average net selling price per metric ton	$	203.56	$	273.49
Cash cost of sales per metric ton	$	126.36	$	148.56

We produced 1.8 million metric tons of steelmaking coal for the three months ended September 30, 2023 compared to 1.5 million metric tons for the three months ended September 30, 2022, representing a 21% increase. The increased production drove an increase in sales as both Mine No. 4 and Mine No. 7 operated at higher capacity levels in the third quarter of 2023 due to the returning employees from the labor strike compared to the third quarter of 2022.

Sales for the three months ended September 30, 2023 were $416.9 million compared to $371.9 million for the three months ended September 30, 2022. The $45.0 million increase in sales was primarily driven by a $188.2 million increase in sales due to a 51% or 0.7 million metric ton increase in steelmaking coal sales volume offset partially by a $143.2 million decrease in sales related to a $69.93 per metric ton decrease in the average net selling price per metric ton of steelmaking coal. The 51% increase in sales volumes was driven by improved performance by our rail transportation provider and the McDuffie terminal, which enabled us to export more steelmaking coal and lower our excess inventory levels. The average net selling price of our steelmaking coal decreased 26% from the $273.49 per metric ton in the third quarter of 2022 to $203.56 per metric ton.

24

For the three months ended September 30, 2023, our geographic customer mix was 39% in Europe, 39% in Asia and 22% in South America. For the three months ended September 30, 2022, our geographic customer mix was 62% in Europe, 21% in Asia and 17% in South America. Our geographic customer mix typically varies each period based on the timing of customer orders and shipments.

Other revenues for the three months ended September 30, 2023 were $6.6 million compared to $18.2 million for the three months ended September 30, 2022. Other revenues are comprised of revenue derived from our natural gas operations, gains on sales and disposals of property, plant and equipment and land, changes in the fair value of our natural gas swap contracts, as well as earned royalty revenue. The $11.6 million decrease in other revenues is primarily due to a decrease in the Southern Louisiana natural gas price average of $6.97 per Million British Thermal Unit ("MMBtu") or 72% for the three months ended September 30, 2023 as compared to the prior year comparable period.

Cost of sales was $260.4 million, or 61.5% of total revenues, for the three months ended September 30, 2023, compared to $203.4 million, or 52.1% of total revenues for the three months ended September 30, 2022. The $57.0 million increase is primarily driven by a $102.2 million increase due to a 51% or 0.7 million metric ton increase in steelmaking coal sales volumes offset partially by a $45.5 million decrease due to decrease in transportation and royalty costs on lower average net selling prices. For the three months ended September 30, 2023 cost of production represented 62% of cost of sales and transportation and royalties accounted for approximately 38% compared to cost of production of 53% and transportation and royalties of 47% for the three months ended September 30, 2022. The increase in cost of production is primarily driven by increased labor costs due to the returning employees from the labor strike and the decreased transportation and royalty costs is driven by lower average net selling prices and its impact on our transportation and royalty costs.

Depreciation and depletion expenses were $34.0 million, or 8.0% of total revenues, for the three months ended September 30, 2023, compared to $30.8 million, or 7.9% of total revenues for the three months ended September 30, 2022. The $3.2 million increase in depreciation and depletion is primarily driven by an increase in met coal sales volume as depreciation and depletion is first capitalized into coal inventory and relieved when the tons are sold.

Selling, general and administrative expenses were $11.1 million, or 2.6% of total revenues, for the three months ended September 30, 2023, compared to $10.6 million, or 2.7% of total revenues, for the three months ended September 30, 2022. The $0.6 million increase in selling, general and administrative expenses for the period is due to an increase in employee related expenses.

Business interruption expenses were $0.3 million and $7.1 million for the three months ended September 30, 2023 and 2022, respectively. The decrease in business interruption expenses is due to the labor union ending the strike it initiated on April 1, 2021. These expenses in the three months ended September 30, 2023 represent ongoing legal expenses associated with labor negotiations and the expenses in the three months ended September 30, 2022 represent non-recurring expenses that were directly attributable to the labor strike for incremental safety and security, legal and labor negotiations and other expenses. We expect to incur ongoing legal expenses associated with the labor negotiations.

Idle mine expenses were $5.4 million for the three months ended September 30, 2022. These expenses represent idle mine expenses incurred in connection with reduced operations at Mine No. 7 and Mine No. 4, such as electricity, insurance and maintenance labor.

Interest income, net was $7.3 million, or 1.7% of total revenues, for the three months ended September 30, 2023, compared to interest expense, net of $5.7 million, or 1.5% of total revenues, for the three months ended September 30, 2022. The change is primarily driven by an increase in interest income combined with a decrease in interest on our outstanding senior secured notes due to the early extinguishment of debt.

For the three months ended September 30, 2023, we recognized a loss on early extinguishment of debt of $11.7 million upon the extinguishment of $146.1 million of our Notes. The loss on early extinguishment of debt represents a premium paid to retire the debt, accelerated amortization of debt discount, and fees incurred in connection with the transaction.

Other expenses were $1.1 million, or 0.3% of total revenues for the three months ended September 30, 2023. These expenses represent non-recurring expenses incurred in connection with the ransomware attack. We do not anticipate any additional material expenses in the future related to this incident.

For the three months ended September 30, 2023, we recognized income tax expense of $16.8 million. We estimated our annual effective tax rate and applied this effective tax rate to our year-to-date pretax income at the end of the interim reporting period. The $16.8 million income tax expense for the three months ended September 30, 2023, includes a benefit related to depletion and Internal Revenue Code ("IRC") Section 250 Deduction: Foreign-Derived Intangible Income ("FDII").

25

The Tax Cuts and Jobs Act ("TCJA") was enacted on December 22, 2017 and enacted IRC Section 250 Deduction: FDII, which provides for, among other things, a deduction of 37.5% with respect to foreign-derived intangible income, which reduces the statutory tax rate from 21% to 13.125%. Beginning in 2026, the deduction is reduced from 37.5% to 22.5% of foreign-derived intangible income. We have historically not been eligible to claim the deduction due to the deduction being limited to taxable income and our ability to utilize our net operating losses to offset taxable income.

For the three months ended September 30, 2022, we recognized income tax expense of $20.3 million, which was principally offset by the utilization of federal net operating loss carryforwards ("NOLs") for cash tax purposes. We estimated our annual effective tax rate and applied this effective tax rate to our year-to-date pretax income at the end of the interim reporting period.

Sales and cost of sales components on a per unit basis were as follows: 

	For the nine months ended September 30,
	2023		2022
Met Coal (metric tons in thousands)
Metric tons sold	5,429		3,782
Metric tons produced	5,149		4,397
Average net selling price per metric ton	$	237.32	$	364.27
Cash cost of sales per metric ton	$	132.49	$	139.15

We produced 5.1 million metric tons of steelmaking coal for the nine months ended September 30, 2023 compared to 4.4 million metric tons for the nine months ended September 30, 2022, representing a 17% increase. The increased production drove an increase in sales as both Mine No. 4 and Mine No. 7 operated at higher capacity levels in the nine months ended

26

September 30, 2023 due to the returning employees from the labor strike in February 2023 compared to the nine months ended September 30, 2022.

Sales for the nine months ended September 30, 2023 were $1.3 billion compared to $1.4 billion for the nine months ended September 30, 2022. The 6.5% decrease in sales was primarily driven by a $689.2 million decrease in sales related to a $126.94 per metric ton decrease in the average net selling price per metric ton of steelmaking coal offset partially by a $600.0 million increase in sales due to a 44% or 1.6 million metric ton increase in steelmaking coal sales volume. The 44% increase in sales volumes was driven by increased production due to both Mine No. 4 and Mine No. 7 operating at higher capacity levels combined with improved performance by our rail transportation provider and the McDuffie Terminal.

For the nine months ended September 30, 2023, our geographic customer mix was 46% in Europe, 31% in Asia, 22% in South America, and 1% in the United States. For the nine months ended September 30, 2022, our geographic customer mix was 63% in Europe, 21% in Asia and 16% in South America. Our geographic customer mix typically varies each period based on the timing of customer orders and shipments.

Other revenues for the nine months ended September 30, 2023 were $24.4 million compared to $16.3 million for the nine months ended September 30, 2022. Other revenues are comprised of revenue derived from our natural gas operations, gains on sales and disposals of property, plant and equipment and land, changes in the fair value of our natural gas swap contracts, as well as earned royalty revenue. The $8.1 million increase in other revenues is primarily due to the prior year including a $27.7 million loss recognized on the fair value adjustment related to our natural gas swap contracts due to an increase in natural gas futures at that time offset partially by a decrease in the Southern Louisiana natural gas price average of $4.48 per MMBtu or 61% for the nine months ended September 30, 2023 as compared to the prior year comparable period.

Cost of sales (exclusive of items shown separately below) was $723.5 million, or 55.1% of total revenues, for the nine months ended September 30, 2023, compared to $529.9 million, or 38.0% of total revenues for the nine months ended September 30, 2022. The $193.6 million increase is primarily driven by a 44% or 1.6 million metric ton increase in steelmaking coal sales volume. For the nine months ended September 30, 2023 cost of production represented 60% of cost of sales and transportation and royalties accounted for approximately 40% compared to cost of production of 50% and transportation and royalties of 50% for the three months ended September 30, 2022. The increase in cost of production is primarily driven by increased labor costs due to the returning employees from the labor strike in February 2023 and the decreased transportation and royalty costs is driven by lower average net selling prices and its impact on our transportation and royalty costs.

Depreciation and depletion expenses were $101.8 million, or 7.8% of total revenues, for the nine months ended September 30, 2023, compared to $87.0 million, or 6.2% for the nine months ended September 30, 2022. The $14.8 million increase in depreciation and depletion is primarily driven by a 44% or 1.6 million metric ton increase in steelmaking coal sales volume as depreciation and depletion is first capitalized into coal inventory and relieved when the tons are sold.

Selling, general and administrative expenses were $38.8 million, or 3.0% of total revenues, for the nine months ended September 30, 2023, compared to $37.0 million, or 2.7% of total revenues, for the nine months ended September 30, 2022. The $1.8 million increase in selling, general and administrative expenses for the period is due to an increase in employee related expenses.

Business interruption expenses were $8.1 million and $20.1 million for the nine months ended September 30, 2023 and 2022, respectively. These expenses decreased compared to the prior period primarily due to the end of the labor strike in February 2023 and represent non-recurring expenses that are directly attributable to the labor strike for incremental safety and security, legal and labor negotiations and other expenses. We expect to incur ongoing legal expenses associated with the labor negotiations.

Idle mine expenses were $10.1 million for the nine months ended September 30, 2022. These expenses represent idle mine expenses incurred in connection with reduced operations at Mine No. 7 and Mine No. 4, such as electricity, insurance and maintenance labor.

Interest income, net was $14.9 million, or 1.1% of total revenues, for the nine months ended September 30, 2023, compared to interest expense, net of $20.7 million, or 1.5% of total revenues, for the nine months ended September 30, 2022. The change is primarily driven by an increase in interest income combined with a decrease in interest expense on our outstanding senior secured notes due to the early extinguishment of debt.

27

For the nine months ended September 30, 2023, we recognized a loss on early extinguishment of debt of $11.7 million upon the extinguishment of $146.1 million of our Notes. The loss on early extinguishment of debt represents a premium paid to retire the debt, accelerated amortization of debt discount, and fees incurred in connection with the transaction.

Other expense for the nine months ended September 30, 2023 represent non-recurring expenses incurred in connection with the ransomware attack and proceeds received from the Chapter 11 Cases from Walter Energy, Inc.. We do not anticipate any additional material expenses in the future related to this ransomware incident. Other income for the nine months ended September 30, 2022 represents proceeds received from the Chapter 11 Cases from Walter Energy, Inc.

For the nine months ended September 30, 2023, we recognized income tax expense of $60.4 million. We estimated our annual effective tax rate and applied this effective tax rate to our year-to-date pretax income at the end of the interim reporting period. The $60.4 million income tax expense for the nine months ended September 30, 2023, includes a benefit related to depletion and Internal Revenue Code ("IRC") Section 250 Deduction: Foreign-Derived Intangible Income ("FDII"). The Tax Cuts and Jobs Act ("TCJA") was enacted on December 22, 2017 and enacted IRC Section 250 Deduction: FDII, which provides for, among other things, a deduction of 37.5% with respect to foreign-derived intangible income, which reduces the statutory tax rate from 21% to 13.125%. Beginning in 2026, the deduction is reduced from 37.5% to 22.5% of foreign-derived intangible income. We have historically not been eligible to claim the deduction due to the deduction being limited to taxable income and our ability to utilize our net operating losses to offset taxable income. For the nine months ended September 30, 2022, we recognized income tax expense of $122.1 million, which was principally offset by the utilization of federal NOLs for cash tax purposes. We estimated our annual effective tax rate and applied this effective tax rate to our year-to-date pretax income at the end of the interim reporting period.

Liquidity and Capital Resources

Overview

Our sources of cash have been steelmaking coal and natural gas sales to customers, proceeds received from the Notes (as defined below) and access to our ABL Facility. Historically, our primary uses of cash have been for funding the operations of our coal and natural gas production operations, working capital, our capital expenditures, our reclamation obligations, payment of principal and interest on our Notes, professional fees and other non-recurring transaction expenses. In addition, we used available cash on hand to repurchase shares of common stock and to pay our quarterly and special dividends, each of which reduces or reduced cash and cash equivalents.

Going forward, we will use cash to fund debt service payments on our Notes, the ABL Facility and our other indebtedness, to fund operating activities, working capital, capital expenditures, our reclamation obligations, professional fees and other non-recurring transaction expenses and strategic investments, the development of Blue Creek, and, if declared, to pay our quarterly and/or special dividends. Our ability to fund our capital needs, including the development of Blue Creek, going forward will depend on our ongoing ability to generate cash from operations and borrowing availability under the ABL Facility, and, in the case of any future strategic investments, capital needs, the development of Blue Creek, or special dividends financed partially or wholly with debt financing and our ability to access the capital markets to raise additional capital.

Our ability to generate positive cash flow from operations in the future will be, at least in part, dependent on continued stable global economic conditions and a resolution of the CBA contract negotiations with the labor union representing certain of our hourly employees. There remains uncertainty as to the effects of new COVID-19 variants on the global economy, which in turn may, among other things, impact our ability to generate positive cash flows from operations, fund capital expenditure needs and successfully execute and fund key initiatives, such as the development of Blue Creek.

Our total liquidity as of September 30, 2023 was $810.1 million, consisting of cash and cash equivalents of $686.8 million and $123.3 million available under our ABL Facility. As of September 30, 2023, no loans were outstanding under the ABL Facility and there were $8.7 million of letters of credit issued and outstanding under the ABL Facility.

During the first quarter of 2023, we repurchased in the open market and extinguished approximately $8.8 million principal amount of our Notes at a discount to par value. The discounts to par value and the interest expense savings from this open-market purchase is estimated to be approximately $4.0 million through the maturity of our Notes. In connection with the extinguishment of our Notes, we recognized a loss on early extinguishment of debt of $0.1 million which is included in interest income (expense), net in the Condensed Statements of Operations. In addition, in the third quarter of 2023, we retired approximately $146.1 million of our Notes and recognized a loss on early extinguishment of debt of $11.7 million, which represents a premium paid to retire the debt, accelerated amortization of debt discount, net, and fees incurred in connection with the transaction.

28

In the future, we may, at any time and from time to time, seek to retire or purchase additional Notes in open-market purchases, privately negotiated transactions or otherwise. Such repurchases or exchanges, if any, will be upon such terms and at such prices as we may determine, and will depend on prevailing market conditions, our liquidity requirements, contractual restrictions, if any, and other factors.

We are responsible for medical and disability benefits for black lung disease under the Federal Coal Mine Health and Safety Act of 1969, as amended. Beginning on April 1, 2016 through May 31, 2018, we were insured under a guaranteed cost insurance policy, through a third-party insurance carrier, for black lung claims raised by any employee subsequent to the acquisition of certain assets of Walter Energy. Beginning on June 1, 2018 through May 31, 2020, we had a deductible policy where we are responsible for the first $0.5 million for each black lung claim. Since June 1, 2020, we have a deductible policy where we are responsible for the first $1.0 million for each black lung claim.

In addition, in connection with the acquisition of certain assets of Walter Energy, we assumed all black lung liabilities of Walter Energy and its U.S. subsidiaries incurred prior to March 31, 2016, for which we are self-insured. We have posted $18.6 million in surety bonds and $8.9 million of collateral recognized as short-term investments in addition to maintaining a black lung trust of $2.1 million that was acquired from Walter Energy. We received a letter from the U.S. Department of Labor ("DOL") on February 21, 2020 under its new process for self-insurance renewals that would require us to increase the amount of collateral posted to $39.8 million, but we have appealed such increase. We received another letter from the DOL on December 8, 2021 requesting additional information to support our appeal of the collateral requested by the DOL. On February 9, 2022, the DOL held a conference call with representatives from the Company related to our appeal. On July 12, 2022, we received a decision on our appeal from the DOL lowering the amount of collateral required to be posted from $39.8 million to $28 million. We appealed this decision. In addition, on January 19, 2023, the DOL proposed revisions to regulations under the Black Lung Benefits Act governing authorization of self-insurers. The proposed rules requires, among other requirements, all self-insured operators to post security equal to 120 percent of their projected black lung liabilities.

In the ordinary course of our business, we are required to provide surety bonds and letters of credit to provide financial assurance for certain transactions and business activities. Federal and state laws require us to obtain surety bonds or other acceptable security to secure payment of certain long-term obligations including mine closure or reclamation costs and other miscellaneous obligations. As of September 30, 2023, we had outstanding surety bonds and letters of credit with parties for post-mining reclamation at all of our mining operations totaling $44.0 million, $18.6 million as collateral for self-insured black lung related claims and $5.2 million for miscellaneous purposes.

We believe that our future cash flows from operations, together with cash on our balance sheet and proceeds from the borrowings under our ABL Facility, will provide adequate resources to fund our debt service payments and planned operating and capital expenditure needs, including the development of Blue Creek, for at least the next twelve months and beyond. However, we will continue to assess our liquidity needs in light of the ongoing CBA contract negotiations with the labor union representing certain of our hourly employees and the ongoing impact of inflation.

The Company's principal contractual commitments include repayments of long-term debt and related interest, potential minimum throughput payments associated with our rail and port providers, asset retirement obligation payments, black lung obligation payments, payments on various coal and land leases, payments under financing lease obligations and payments associated with our natural gas swap contracts. Currently, there are no known trends or expected changes anticipated in future periods that would not be indicative of past results for our contractual commitments.

Refer to the respective notes to our audited financial statements for the year ended December 31, 2022 included in our 2022 Annual Report for further information about our credit facilities and long-term debt (Note 13), commitments and contingencies (Note 16), asset retirement obligations (Note 8), black lung obligations (Note 10), lease payment obligations (Note 14), share repurchase programs (Note 16) and derivative instruments (Note 17).

If our cash flows from operations are less than we require, we may need to incur additional debt or issue additional equity. From time to time, we may need to access the long-term and short-term capital markets to obtain financing. Our access to, and the availability of, financing on acceptable terms and conditions in the future will be affected by many factors, including: (i) our credit ratings, (ii) the liquidity of the overall capital markets, (iii) the current state of the global economy and (iv) restrictions in our ABL Facility, the indenture governing the Notes (the "Indenture"), and any other existing or future debt agreements. There can be no assurance that we will have or continue to have access to the capital markets on terms acceptable to us or at all.

Statements of Cash Flows

Cash balances were $686.8 million and $829.5 million at September 30, 2023 and December 31, 2022, respectively.

The following table sets forth, a summary of the net cash provided by (used in) operating, investing and financing activities for the period (in thousands): 

	For the three months ended September 30,
	2023		2022
Net cash provided by operating activities	$	456,018	$	646,910
Net cash used in investing activities	(344,752)		(156,679)
Net cash used in financing activities	(253,935)		(140,404)
Net (decrease) increase in cash and cash equivalents	$	(142,669)	$	349,827

Operating Activities

Net cash flows from operating activities consist of net income adjusted for noncash items, such as depreciation and depletion of property, plant and equipment and mineral interests, deferred income tax expense, stock-based compensation, amortization of debt issuance costs and debt discount, accretion of asset retirement obligations, mark-to-market (gains) losses on gas hedges, loss on early extinguishment of debt and changes in net working capital.

Net cash provided by operating activities was $456.0 million for the nine months ended September 30, 2023, and was primarily attributed to net income of $349.8 million adjusted for depreciation and depletion expense of $101.8 million, deferred income tax expense of $52.4 million, stock based compensation expense of $14.5 million, accretion of asset retirement obligations of $2.9 million, amortization of debt issuance costs and debt discount of $1.7 million, loss on early extinguishment of debt of $11.7 million, and an increase in our net working capital of $84.6 million since December 31, 2022. The increase in our working capital was primarily driven by increases in accounts receivable and decreased accrued expenses and accounts payable offset partially by a decrease in inventories. The increase in trade accounts receivable reflects higher sales volumes and the timing of sales and the decrease in inventories is due to greater sales volumes than production. The decrease in accrued expenses and accounts payable is due to the timing of payments.

Net cash provided by operating activities was $646.9 million for the nine months ended September 30, 2022, and was primarily attributed to net income of $541.6 million adjusted for deferred income tax expense of $122.2 million, depreciation and depletion expense of $87.0 million, stock based compensation expense of $14.3 million, mark-to-market loss on gas hedges of $4.0 million, accretion of asset retirement obligations of $2.7 million, amortization of debt issuance costs and debt discount of $2.9 million and an increase in our net working capital of $130.7 million since December 31, 2021. The increase in our working capital was primarily driven by increases in accounts receivable and inventory offset partially by an increase in accrued expenses and other current liabilities. The increase in trade accounts receivable reflects higher sales prices and the timing of sales and the increase in inventories is due to greater production than sales volumes and continued shipment delays resulting from port maintenance, lack of railcar availability and port congestion. The increase in accrued expenses and other current liabilities is due to the restart of Mine No. 4 in the first quarter of 2022 combined with higher costs on price sensitive transportation and royalty costs, and the impact of inflation.

Investing Activities

Net cash used in investing activities was $344.8 million and $156.7 million for the nine months ended September 30, 2023 and 2022, respectively, primarily due to purchases of property, plant and equipment and mine development. Capital expenditures during the nine months ended September 30, 2023 for the development of Blue Creek was $191.3 million. The current period also includes $2.4 million cash paid to acquire the remaining ownership interest in gas wells owned by an independent third party. The prior year period also includes $3.5 million cash used in connection with the acquisition of leased mineral rights and $2.5 million net cash acquired in connection with the acquisition of the remaining 50% interest in BWM and BWT.

Financing Activities

Net cash used in financing activities was $253.9 million for the nine months ended September 30, 2023, primarily due to the retirements of debt related to our senior notes of $162.4 million, payment of regular quarterly and special dividends of $57.4 million and principal repayments of finance lease obligations of $25.0 million. Net cash used in financing activities was $140.4 million for the nine months ended September 30, 2022, primarily due to the payment of regular quarterly and special

30

dividends of $76.5 million, retirements of debt related to our senior notes of $37.8 million and principal repayments of finance lease obligations of $22.4 million.

Capital Allocation Policy

On May 17, 2017, the Board adopted the Capital Allocation Policy of paying a quarterly cash dividend of $0.05 per share. In February 2022, we announced that the Board approved an increase in the regular quarterly cash dividend by 20%, from $0.05 per share to $0.06 per share. In February 2023, we announced that the Board approved an increase in the regular quarterly cash dividend by 17%, from $0.06 per share to $0.07 per share. Our strategy continues to be focused on optimizing our capital structure to improve returns to stockholders, through special cash dividends, while allowing flexibility for us to develop our strategic growth project Blue Creek. We intend on returning cash to stockholders in stronger price markets where we are generating significant amounts of cash flow, and less cash to stockholders during weaker markets. We also intend on using stock repurchases when there is no short- or long-term use for additional cash that will deliver meaningful value to stockholders. We have paid a regular quarterly cash dividend every quarter since the Board adopted the Capital Allocation Policy.

The Capital Allocation Policy states the following: In addition to the regular quarterly dividend and to the extent that the Company generates excess cash that is beyond the then current requirements of the business, the Board may consider returning all or a portion of such excess cash to stockholders through a special dividend or implementation of a stock repurchase program. Any future dividends or stock repurchases will be at the discretion of the Board and subject to consideration of a number of factors, including business and market conditions, future financial performance and other strategic investment opportunities. The Company will also seek to optimize its capital structure to improve returns to stockholders while allowing flexibility for the Company to pursue selective strategic growth opportunities that can provide compelling stockholder returns.

During the nine months ended September 30, 2023, we have paid $57.4 million of regular quarterly and special cash dividends under the Capital Allocation Policy.

Regular Quarterly Dividend

On February 9, 2023, our Board approved an increase in the regular quarterly cash dividend by 17% and declared a regular quarterly cash dividend of $0.07 per share, totaling approximately $3.6 million, which was paid on February 27, 2023 to stockholders of record as of the close of business on February 20, 2023.

On April 25, 2023, our Board declared a regular quarterly cash dividend of $0.07 per share, totaling approximately $3.7 million, which was paid on May 12, 2023, to stockholders of record as of the close of business on May 5, 2023.

On July 28, 2023, our Board declared a regular quarterly cash dividend of $0.07 per share, totaling approximately $3.7 million, which was paid August 14, 2023, to stockholders of record as of the close of business on August 7, 2023.

On October 24, 2023, our Board declared a regular quarterly cash dividend of $0.07 per share, totaling approximately $3.7 million, which will be paid November 10, 2023, to stockholders of record as of the close of business on November 3, 2023.

Special Dividend

On February 13, 2023, our Board declared a special cash dividend of $0.88 per share, totaling approximately $46.4 million, which was paid on March 7, 2023 to stockholders of record as of the close of business on February 28, 2023.

ABL Facility

The ABL Facility will mature on December 6, 2026. As of September 30, 2023, no loans were outstanding under the ABL Facility and there were $8.7 million of letters of credit issued and outstanding under the ABL Facility. At September 30, 2023, we had $123.3 million of availability under the ABL Facility.

Revolving loan (and letter of credit) availability under the ABL Facility is subject to a borrowing base, which at any time is equal to the sum of certain eligible billed and unbilled accounts, certain eligible inventory, certain eligible supplies inventory and qualified cash, in each case, subject to specified advance rates. The borrowing base availability is subject to certain reserves, which may be established by the agent in its reasonable credit discretion. The reserves may include rent

31

reserves, lower of cost or market reserve, port charges reserves and any other reserves that the Agent determines in its reasonable credit judgment to the extent such reserves relate to conditions that could reasonably be expected to have an adverse effect on the value of the collateral included in the borrowing base.

Borrowings under the ABL Facility bear interest at a rate equal to either (i) the Secured Overnight Financing Rate ("SOFR"), plus a credit adjustment spread, ranging currently from approximately 11 bps to 43 bps depending on the interest period selected by us, or (ii) an alternate base rate plus, in each case of the foregoing (i) and (ii), an applicable margin, which is determined based on the average availability of the commitments under the ABL Facility, ranging currently from 150 bps to 200 bps or 50 bps to 100 bps, respectively. In addition to paying interest on the outstanding borrowings under the ABL Facility, we are required to pay a fee in respect of unutilized commitments, which is based on the availability of the commitments under the ABL Facility, ranging from 25 bps to 37.5 bps. We are also required to pay a fee on amounts available to be drawn under outstanding letters of credit under the ABL Facility at a rate not in excess of 200 bps, and certain administrative fees.

The ABL Facility contains customary covenants for asset-based credit agreements of this type, including among other things: (i) requirements to deliver financial statements, other reports and notices; (ii) restrictions on the existence or incurrence of certain indebtedness; (iii) restrictions on the existence or incurrence of certain liens; (iv) restrictions on making certain restricted payments; (v) restrictions on making certain investments; (vi) restrictions on certain mergers, consolidations and asset dispositions; (vii) restrictions on certain transactions with affiliates; and (viii) restrictions on modifications to certain indebtedness. Additionally, the ABL Facility contains a springing fixed charge coverage ratio of not less than 1.00 to 1.00, which ratio is tested if availability under the ABL Facility is less than a certain amount. As of September 30, 2023, we were not subject to this covenant. Subject to customary grace periods and notice requirements, the ABL Facility also contains customary events of default.

We were in compliance with all applicable covenants under the ABL Facility as of September 30, 2023.

Senior Secured Notes

On December 6, 2021, we issued $350.0 million in aggregate principal amount of 7.875% senior secured notes due 2028 (the “Notes”) at an initial price of 99.343% of their face amount. The Notes were issued to qualified institutional buyers pursuant to Rule 144A under the Securities Act of 1933, as amended (the “Securities Act”), and to certain non-U.S. persons in transactions outside the United States in accordance with Regulation S under the Securities Act. We used the net proceeds of the offering of the Notes, together with cash on hand, to fund the redemption of all of our outstanding 8.00% senior secured notes due 2024 (the “Existing Notes”), including payment of the redemption premium in connection with such redemption.

The Notes will accrue interest at a rate of 7.875% per year from December 6, 2021. Interest on the Notes will be payable on June 1 and December 1 of each year, commencing on June 1, 2022. The Notes will mature on December 1, 2028.

During the nine months ended September 30, 2023, we repurchased in the open market and extinguished approximately $8.0 million principal amount of our Notes. In connection with the extinguishment of our Notes, we recognized a loss on early extinguishment of debt of $0.1 million which is included in interest income (expense), net in the Condensed Statements of Operations.

Offers to Purchase the Notes

On August 9, 2023, we commenced an offer to purchase (the “Restricted Payment Offer”), in cash, up to $150,000,000 principal amount of its outstanding Notes, at a repurchase price of 103% of the aggregate principal amount of such Notes, plus accrued and unpaid interest with respect to such Notes to, but not including, the date of repurchase (the “Restricted Payment Repurchase Price”). Concurrently with, but separate from, the Restricted Payment Offer, we commenced a cash tender offer (the “Tender Offer” and, together with the Restricted Payment Offer, the “Offers”) to purchase up to $150,000,000 principal amount of the Notes at a repurchase price of 104.25% of the aggregate principal amount of such Notes, plus accrued and unpaid interest to, but not including, the date of repurchase (the “TO Repurchase Price”). The Offers expired on September 7, 2023 (the “Expiration Date”).

Restricted Payment Offer

As of the Expiration Date, $200,000 aggregate principal amount of the Notes were validly tendered and not validly withdrawn pursuant to the Restricted Payment Offer. Pursuant to the terms of the Restricted Payment Offer:

(1) an automatic pro ration factor of 49.5674% was applied to the $200,000 aggregate principal amount of the Notes that were validly tendered and not validly withdrawn in the Restricted Payment Offer (rounded down to avoid the purchase of

Notes in a principal amount other than in integrals of $1,000), which resulted in $99,000 aggregate principal amount of the Notes (the “RP Pro-Rated Tendered Notes”);

(2) we accepted all $99,000 aggregate principal amount of the RP Pro-Rated Tendered Notes for payment of the Restricted Payment Repurchase Price in cash; and

(3) the remaining balance of $101,000 aggregate principal amount of the Notes tendered that were not RP Pro-Rated Tendered Notes were not accepted for payment and were returned to the tendering holder of the Notes.

We consummated the Restricted Payment Offer on September 8, 2023.

Accordingly, pursuant to the terms of the Indenture, we will have the ability from time to time in the future to make one or more restricted payments (the "Proposed Restricted Payment") in the form of special dividends to holders of our common stock and/or repurchases of our common stock in the aggregate amount of up to $299,901,000 consistent with the terms of the Capital Allocation Policy adopted by our Board. Any future Proposed Restricted Payments will be at the discretion of the Board and subject to a number of factors and there can be no assurance that we will make any Proposed Restricted Payments in the future.

Tender Offer

As of the Expiration Date, $294,770,000 aggregate principal amount of the Notes were validly tendered and not validly withdrawn pursuant to the Tender Offer. Pursuant to the terms of the Tender Offer:

(1) an automatic pro ration factor of 49.5674% was applied to the $294,770,000 aggregate principal amount of the Notes that were validly tendered and not validly withdrawn in the Tender Offer (rounded down to avoid the purchase of Notes in a principal amount other than in integrals of $1,000), which resulted in $146,002,000 aggregate principal amount of the Notes (the “TO Pro-Rated Tendered Notes”);

(2) we accepted all $146,002,000 aggregate principal amount of the TO Pro-Rated Tendered Notes for payment of the TO Repurchase Price in cash; and

(3) the remaining balance of $148,768,000 aggregate principal amount of the Notes tendered that were not TO Pro-Rated Tendered Notes were not accepted for payment and were returned to the tendering holder of the Notes.

We consummated the Tender Offer on September 11, 2023.

In connection with the payments for the RP Pro-Rated Tendered Notes and the TO Pro-Rated Tendered Notes, we recognized a loss on early extinguishment of debt of $11.7 million during the three and nine months ended September 30, 2023.

Capital Expenditures

Our mining operations require investments to maintain, expand, upgrade or enhance our operations and to comply with environmental regulations. Maintaining and expanding mines and related infrastructure is capital intensive. Specifically, the exploration, permitting and development of met coal reserves, mining costs, the maintenance of machinery and equipment and compliance with applicable laws and regulations require ongoing capital expenditures. The cost of our capital expenditures are also impacted by inflation and any prolonged inflation could result in higher costs and decreased margins and earnings. While a significant amount of the capital expenditures required at our mines has been spent, we must continue to invest capital to maintain our production. In addition, any decisions to increase production at our mines and the development of the high-quality met coal recoverable reserves at Blue Creek could also affect our capital needs or cause future capital expenditures to be higher than in the past and/or higher than our estimates.

To fund our capital expenditures, we may be required to use cash from our operations, incur debt or sell equity securities. Our ability to obtain bank financing or our ability to access the capital markets for future equity or debt offerings may be limited by our financial condition at the time of any such financing or offering and the covenants in our current or future debt agreements, as well as by general economic conditions, contingencies and uncertainties, including as a result of the COVID-19 pandemic, that are beyond our control.

33

Our capital expenditures were $310.8 million and $120.0 million for the nine months ended September 30, 2023 and September 30, 2022, respectively. Capital expenditures for these periods are primarily related to investments required to develop Blue Creek and the portal facilities at Mine No. 4 as well as expenditures necessary to maintain our property, plant and equipment. Capital expenditures for the development of Blue Creek for the nine months ended September 30, 2023 were $191.3 million and $238.4 million has been spent on this project to date. Our deferred mine development costs were $31.5 million and $35.7 million for the nine months ended September 30, 2023 and September 30, 2022, respectively, and relate to Mine No. 4 and the development of Blue Creek.

Our capital spending is expected to range from $420.0 million to $485.0 million for the full year 2023, consisting of sustaining capital expenditures of approximately $95.0 to $105.0 million and discretionary capital expenditures of approximately $325.0 to $380.0 million for the development of Blue Creek and 4 North portal construction and payments on two extra sets of longwall shields. Our sustaining capital expenditures include expenditures related to longwall operations, continuous miners, new ventilation, and bleeder shafts.

Update on the Development of Blue Creek

More than a year after the relaunch of the Blue Creek mine development in May 2022, Warrior has initiated important and highly beneficial project scope changes that will require incremental capital expenditures over the life of the project while lowering operating costs, increasing flexibility to manage risks, and make better use of multi-channel transportation methods. Most of these scope changes are transportation and logistics-related, with additional amounts related to inflation for these changes only. They are expected to increase total capital expenditures for the Blue Creek mine by approximately $120 - $130 million over the remainder of the project development period.

Transportation Initiatives - While the Company originally planned on a single channel to transport coal from the Blue Creek mine via an overland belt to a third-party owned and operated barge loadout facility, it now plans to build a belt conveyor system to a railroad loadout to transport the majority of the coal which is expected to de-risk a single channel to market, lower operating cost and move volumes faster to the port. Warrior will also build and operate a barge loadout itself rather than utilizing a third-party provider. The Company believes that the potential economic benefits associated with this scope change should provide Warrior with an inherently robust and cost competitive outbound logistics model that will provide additional flexibility to manage alternative transportation methods. The inclusion of the benefits and incremental capital expenditures relating to these specific scope changes did not have a material impact to the project economic metrics of net present value (“NPV”) and internal rate of return.

In addition, the Company has experienced inflationary cost increases ranging from 25 to 35 percent in both operating expenses and capital expenditures for its existing mining operations since late 2021. The Company is also experiencing inflationary pressures at Blue Creek, especially in relation to labor, construction materials and certain equipment, that is expected to continue during the remainder of the project development period. As a number of key material contracts are currently being negotiated, and due to uncertainty regarding future inflation rates, the Company is not providing an estimate of the impact of inflation at this time. However, as the Company negotiates and enters into contracts for the larger project components, the Company expects that more information will become available to allow it to provide revised guidance. While cost inflation has impacted the cost of the project, these inflationary pressures are expected to be offset by an inflationary increase in the long-term price assumption for steelmaking coal.

The Company is also employing a number of techniques to mitigate the impact of the inflationary costs such as ordering and purchasing equipment earlier, offering earlier payments for additional discounts on both equipment and services and other contract term modifications.

Subject to the considerations discussed above, our revised estimate of capital expenditures in 2023 for the development of the Blue Creek mine is approximately $250 to $300 million and is subject to change. The increase in 2023 capital expenditure estimate is primarily driven by the changes in transportation scope discussed above. The Company currently expects development spending at Blue Creek to be the highest in 2023 and 2024, with 2024 being a similar amount to 2023 that is subject to change. The Company’s strong cash flow generation and current available liquidity, as well as ability to finance $120 to $130 million of capital expenditures through equipment leases, allows us to be opportunistic as we evaluate funding options for Blue Creek with the goal of maintaining an efficient and low-cost of capital.

The project remains on schedule with the first development tons from continuous miner units expected in the third quarter of 2024 and the longwall scheduled to start up in the second quarter of 2026.

Critical Accounting Policies

The financial statements are prepared in conformity with GAAP, which require the use of estimates, judgments and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses in the period presented. Management evaluates these estimates and assumptions on an ongoing basis, using historical experience, consultation with experts and other methods considered reasonable in the particular circumstances. Nevertheless, actual results may differ significantly from management’s estimates.

Our most critical accounting estimates are those that are most important to the presentation of our financial condition and results of operations and require management’s most difficult, subjective and complex judgments, often as a result of the need to make estimates about the effect of matters that are inherently uncertain. These estimates are based upon management’s historical experience and on various other assumptions that we believe are reasonable under the circumstances. Changes in estimates used in these and other items could have a material impact on our financial statements.

As of September 30, 2023, there have been no material changes to our critical accounting estimates as described in the "Critical Accounting Policies" in Part II, Item 7, Management's Discussion and Analysis of Financial Condition and Results of Operations in the 2022 Annual Report.

Off-Balance Sheet Arrangements

In the ordinary course of our business, we are required to provide surety bonds and letters of credit to provide financial assurance for certain transactions and business activities. Federal and state laws require us to obtain surety bonds or other acceptable security to secure payment of certain long-term obligations including mine closure or reclamation costs and other miscellaneous obligations. As of September 30, 2023, we had outstanding surety bonds and letters of credit with parties for post-mining reclamation at all of our U.S. mining operations totaling $44.0 million, for collateral for self-insured black lung related claims totaling $18.6 million and for miscellaneous purposes totaling $5.2 million.

Recently Adopted Accounting Standards

A summary of recently adopted accounting pronouncements is included in Note 2 of the "Notes to Condensed Financial Statements" in this Form 10-Q.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Commodity Price Risk

We are exposed to commodity price risk on sales of steelmaking coal. We sell most of our steelmaking coal under fixed supply contracts primarily with indexed pricing terms and volume terms of up to one to three years. Sales commitments in the steelmaking coal market are typically not long-term in nature, and we are, therefore, subject to fluctuations in market pricing.

We occasionally enter into natural gas swap contracts to hedge the exposure to variability in expected future cash flows associated with the fluctuations in the price of natural gas related to our forecasted sales. Our natural gas swap contracts economically hedge certain risk but are not designated as hedges for financial reporting purposes. All changes in the fair value of these derivative instruments are recorded as other revenues in the Condensed Statements of Operations. Historically, all of our derivative instruments were entered into for hedging purposes rather than speculative trading. As of September 30, 2023, the Company had no natural gas swap contracts outstanding.

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 historically have not entered into any derivative commodity instruments to manage the exposure to changing price risk for supplies.

Credit Risk

Financial instruments that potentially subject us to a concentration of credit risk consist principally of trade receivables. We provide our products to customers based on an evaluation of the financial condition of our customers. In some instances, we require letters of credit, cash collateral or prepayments from our customers on or before shipment to mitigate the

35

risk of loss. Exposure to losses on receivables is principally dependent on each customer’s financial condition. We monitor the exposure to credit losses and maintain allowances for anticipated losses. As of September 30, 2023 and December 31, 2022, the estimated allowance for credit losses was immaterial and did not have a material impact on the Company's financial statements.

Interest Rate Risk

We are exposed to market risk from changes in interest rates. Our Notes have a fixed rate of interest of 7.875% per annum and are payable semi-annually in arrears on June 1 and December 1 of each year.

Our ABL Facility bears an interest rate equal to SOFR, plus a credit adjustment spread, ranging currently from 11 bps to 43 bps, or an alternate base rate plus an applicable margin, which is determined based on the average availability of the commitments under the ABL Facility, ranging currently from 150 bps to 200 bps or 50 bps to 100 bps, respectively. Any debt that we incur under the ABL Facility will expose us to interest rate risk. If interest rates increase significantly in the future, our exposure to interest rate risk will increase. As of September 30, 2023, assuming we had $132.0 million outstanding under our ABL Facility, a 100-basis point increase or decrease in interest rates would increase or decrease our annual interest expense under the ABL Facility by approximately $1.3 million.

Impact of Inflation

We have exposure to inflation for supplies that are used directly or indirectly in the normal course of production, such as belt structure, roof bolts, cable, magnetite, rock dust and other supplies, plus labor and parts on repair and rebuild equipment. These inflationary pressures have contributed to rising costs for us and may continue to do so in the future. We are applying a number of different strategies to mitigate the impact of inflation on our operations, including placing purchase orders earlier, utilizing short-term contracts and leveraging our supplier relationships.

ITEM 4. CONTROLS AND PROCEDURES

Disclosure Controls and Procedures

As required by Rule 13a-15(b) under the Exchange Act, our management, under the supervision and with the participation of our Chief Executive Officer and Chief Financial Officer, has evaluated the effectiveness of our disclosure controls and procedures (as defined in Rules 13a-15(e) under the Exchange Act) as of September 30, 2023. Based on the evaluation of our disclosure controls and procedures as of September 30, 2023, our Chief Executive Officer and Chief Financial Officer have concluded that, as of September 30, 2023, our disclosure controls and procedures were effective to ensure that information required to be disclosed by us in reports that we file or submit under the Exchange Act is (1) recorded, processed, summarized and reported within the time periods specified in the SEC's rules and forms and (2) accumulated and communicated to our management, including our principal executive officer and principal financial officer, as appropriate to allow timely decisions regarding required disclosures.

Changes in Internal Control Over Financial Reporting

There have been no changes in our internal control over financial reporting that occurred during our most recently completed fiscal quarter that materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Limitations on the Effectiveness of Disclosure Controls and Procedures

In designing and evaluating the disclosure controls and procedures, management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives. In addition, the design of disclosure controls and procedures must reflect the fact that there are resource constraints and that management is required to apply judgment in evaluating the benefits of possible controls and procedures relative to their costs.

PART II. OTHER INFORMATION

Item 1. Legal Proceedings.

See Note 9 of the “Notes to Condensed Financial Statements” in this Form 10-Q for a description of current legal proceedings, which is incorporated by reference in this Part II, Item 1.

We and our subsidiaries are parties to a number of other lawsuits arising in the ordinary course of our business. We record costs relating to these matters when a loss is probable and the amount can be reasonably estimated. The effect of the outcome of these matters on our future results of operations cannot be predicted with certainty as any such effect depends on future results of operations and the amount and timing of the resolution of such matters. While the results of litigation cannot be predicted with certainty, we believe that the final outcome of such litigation will not have a material adverse effect on our financial statements.

Item 1A. Risk Factors.

Other than as set forth below, there have been no material changes to the risk factors disclosed in "Risk Factors" in "Part I, Item 1A. Risk Factors" in our 2022 Annual Report and in "Risk Factors" in "Part I, Item 1A. Risk Factors" in our Quarterly Reports on Form 10-Q for the quarters ended March 31, 2023 (the "Q1 2023 Quarterly Report) and June 30, 2023 (the "Q2 2023 Quarterly Report"). Our business, financial condition, operating results and cash flows can be impacted by a number of factors, any one of which could cause actual results to vary materially from recent results or from anticipated future results. In addition to the other information set forth in this Form 10-Q, you should carefully consider the risks discussed in "Part I, Item 1A. Risk Factors" in our 2022 Annual Report and in "Risk Factors" in "Part I, Item 1A. Risk Factors" in our Q1 2023 Quarterly Report and Q2 2023 Quarterly Report, which could materially affect our business, financial condition or future results. However, the risks described in our 2022 Annual Report are not the only risks we face. Additional risks and uncertainties not currently known to us or that we currently deem to be immaterial may become material and adversely affect our business, financial condition and/or operating results.

Terrorist attacks and cyber-attacks or other security breaches may negatively affect our business, financial condition and results of operations and cash flows.

Our business is affected by general economic conditions, fluctuations in consumer confidence and spending, and market liquidity, all of which can decline as a result of numerous factors outside of our control, such as terrorist attacks and acts of war. Future terrorist attacks against U.S. targets, rumors or threats of war, actual conflicts involving the United States or its allies, or military or trade disruptions affecting our customers could cause delays or losses in transportation and deliveries of met coal to our customers, decreased sales of our met coal and extension of time for payment of accounts receivable from our customers. Strategic targets such as energy-related assets may be at greater risk of future terrorist attacks than other targets in the United States. It is possible that any, or a combination, of these occurrences could have a material adverse effect on our business, financial condition and results of operations.

In addition, we have become increasingly dependent upon digital technologies, including information systems, infrastructure and cloud applications and services, to operate our businesses, process and record financial and operating data, communicate with our employees and business partners, analyze seismic and drilling information, estimate quantities of met coal reserves, as well as other activities related to our businesses. We own and operate some of these systems and applications while others are owned and operated by our third-party service providers. In the ordinary course of our business, we and our service providers collect, process, transmit and store data, such as proprietary business information and personally identifiable information. As our dependence on digital technologies has increased, our IT systems and those of third parties are vulnerable to malicious and intentional cyberattacks involving malware and viruses, accidental or inadvertent incidents, the exploitation of security vulnerabilities or “bugs” in software or hardware, among other scenarios. Both the frequency and magnitude of cyberattacks is expected to increase and attackers are becoming more sophisticated. A cyber-attack may involve persons gaining unauthorized access to our digital systems for purposes of gathering, monitoring, releasing, misappropriating or corrupting proprietary or confidential information, or causing operational disruption. Unauthorized physical access to one of our facilities or electronic access to our information systems could result in, among other things, unfavorable publicity, litigation by affected parties, damage to sources of competitive advantage, disruptions to our operations, loss of customers, financial obligations for damages related to the theft or misuse of such information and costs to remediate such security vulnerabilities, any of which could have a substantial impact on our results of operations, financial condition or cash flows. As cyber incidents continue to evolve, we may be required to expend additional resources to continue to modify or enhance our protective measures or to investigate and remediate any vulnerability to cyber incidents. Additionally, we may be unable to anticipate, detect or prevent future attacks, particularly as the methodologies utilized by attackers change frequently or are not recognized until launched, and we may be unable to investigate or remediate incidents because attackers are increasingly using techniques and tools designed to circumvent controls, to avoid detection, and to remove or obfuscate forensic evidence. The COVID-19 pandemic has presented additional operational and cybersecurity risks due to continued work-from-home

37

arrangements that have facilitated increased risk of social engineering events (for example phishing) and of the exploitation of vulnerabilities inherent in many non-corporate networks.

To that end, while we have implemented security protocols, controls, and systems with the intent of maintaining the physical and electronic security of our operations and protecting our and our counterparties’ confidential information and information related to identifiable individuals against unauthorized access. Despite such efforts, we have been and may be subject to security breaches, which have resulted and could result in unauthorized access to our facilities or the information that we are trying to protect. For example, on July 29, 2023, the Company discovered a ransomware attack impacting its on-premises information technology systems, including the theft of certain Company data. Upon learning of the incident, the Company immediately retained external resources to investigate, isolate and contain the threat, and restore the Company’s affected information technology systems, and the Company was able to recover access to all material data. The Company did not incur during the third quarter of 2023, and does not expect to incur in the future, any material cyber-security-related expenses related to the incident.

The Company has strategically chosen to self-insure for cyber-related events, deeming it more cost-effective than bearing the high premiums of third-party insurance. In the future, existing liquidity and cash flows may be insufficient to cover all losses that may be incurred in the continually evolving area of cyber risk.

While the Company was able to manage this incident without any significant disruptions to our operations or any material financial impact, there can be no assurance that we will not be the target of a similar or more sophisticated attack in the future, which could materially adversely affect our business, results of operations, or financial condition.

Exhibit 95

Item 4. Mine Safety Disclosures

Mine Safety and Health Administration Safety Data

Warrior Met Coal, Inc. ("we", "our", or the "Company") is committed to the safety of its employees and the goal of providing an incident-free workplace. To that end, the Company has in place health and safety programs that include regulatory-based training, accident prevention, workplace inspection, emergency preparedness response, accident investigations, and program auditing. These programs are designed to comply with regulatory mining-related coking coal safety and environmental standards. Additionally, the programs provide a basis for promoting a best-in-industry safety practice.

The operation of our mines is subject to regulation by the Mine Safety and Health Administration (“MSHA”) under the Federal Mine Safety and Health Act of 1977 (the “Mine Act”). MSHA inspects our mines on a continual basis and issues various citations and orders when it believes a violation has occurred under the Mine Act. As required by Section 1503 of the Dodd-Frank Wall Street Reform and Consumer Protection Act, each operator of a coal or other mine is required to include certain mine safety results in its periodic reports filed with the Securities and Exchange Commission (the "SEC"). Within this disclosure, we present information regarding certain mining safety and health citations which MSHA has issued with respect to our mining operations. In evaluating this information, consideration should be given to factors such as: (i) the number of citations and orders will vary depending on the size of the 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 sometimes dismissed and remaining citations are often reduced in severity and civil penalty amount.

Duringthe quarter ended September 30, 2023, none of the Company’s mining complexes received written notice from MSHA of (i) 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 or (ii) the potential to have such a pattern.

The first table below presents the total number of specific citations and orders issued by MSHA to the Company and its subsidiaries, together with the total dollar value of the proposed MSHA civil penalty assessments received, during the quarter ended September 30, 2023. The second table presents legal actions pending before the Federal Mine Safety and Health Review Commission ("FMSHRC") for each of our mines as of September 30, 2023, together with the number of legal actions initiated and the number of legal actions resolved during the quarter ended September 30, 2023.

Mining Complex(1) (3)	Section 104 S&S Citations	Section 104(b) Orders	Section 104(d) Citations and Orders	Section 110(b)(2) Violations	Section 107(a) Orders	Proposed MSHA Assessments(2) ($ in thousands)	Fatalities
Warrior Met Coal Mining, LLC, No. 4	76	—	—	—	1	132.5	1
Warrior Met Coal Mining, LLC, No. 7	45	—	3	—	—	187.0	—

(1)MSHA assigns an identification number to each coal mine and may or may not assign separate identification numbers to related facilities such as preparation plants. We are providing the information in the table by mining complex rather than MSHA identification number because we believe that this presentation is more useful to investors. For descriptions of each of these mining operations, please refer to the descriptions under "Part 1, Item 1. Business" and "Part 1, Item 2. Properties" in our Annual Report on Form 10-K for the year ended December 31, 2022. Idle facilities are not included in the table above unless they received a citation, order or assessment by MSHA during the current quarterly reporting period or are subject to pending legal actions.

(2)Not all citations issued during the quarter have been assessed a civil penalty. Thus, amounts listed under this heading are based on assessments that have been proposed, projected proportionally for all enforcement actions issued during the quarter, both Significant and Substantial ("S&S") and non-S&S, regardless of the issuance date of the related citation or order.

(3)The table includes references to specific sections of the Mine Act as follows:

•Section 104(a) Citations include citations for health or safety standards that could significantly and substantially contribute to serious injury if left unabated.

•Section 104(b) Orders represent failures to abate a citation under 104(a) within the period of time prescribed by MSHA and that the period of time prescribed for the abatement should not be further extended. This results in an order of immediate withdrawal from the area of the mine affected by the condition until MSHA determines that the violation has been abated.

•Section 104(d) Citations and Orders are for unwarrantable failure to comply with mandatory health and safety standards where such violation is of such a nature as could significantly or substantially contribute to the cause and effect of a coal or other mine safety or health hazard.

•Section 110(b)(2) Violations are for flagrant violations.

•Section 107(a) Orders are for situations in which MSHA determined an imminent danger existed.

(1)Effective January 27, 2011, the SEC adopted amendments to its rules to implement Section 1503 of the Dodd-Frank Wall Street Reform and Consumer Protection Act (the “final rule”). The final rule modified previous reporting requirements and requires that the total number of legal actions pending before the FMSHRC as of the last day of the time period covered by the report be categorized according to type of proceeding, in accordance with the categories established in the Procedural Rules of FMSHRC. SEC rules require that six different categories of pending legal actions be disclosed. The types of proceedings are listed as follows:

•“29 CFR Part 2700, Subpart B” These legal actions include proceedings initiated under FMSHRC Procedural Rule 29 CFR Part 2700, Subpart B such as contests of citations and orders filed prior to receipt of a proposed penalty assessment from MSHA, contests related to orders for which penalties are not assessed (such as imminent danger orders under Section 107 of the Mine Act), and emergency response plan dispute proceedings.

•“29 CFR Part 2700, Subpart C” These legal actions include proceedings initiated under FMSHRC Procedural Rule 29 CFR Part 2700, Subpart C and are contests of citations and orders after receipt of proposed penalties.

•“29 CFR Part 2700, Subpart D” These legal actions include proceedings initiated under FMSHRC Procedural Rule 29 CFR Part 2700, Subpart D and are complaints for compensation, which are cases under section 111 of the Mine Act.

•“29 CFR Part 2700, Subpart E” These legal actions include proceedings initiated under FMSHRC Procedural Rule 29 CFR Part 2700, Subpart E and are complaints of discharge, discrimination or interference and temporary reinstatement under section 105 of the Mine Act.

•“29 CFR Part 2700, Subpart F” These legal actions include proceedings initiated under FMSHRC Procedural Rule 29 CFR Part 2700, Subpart F such as applications for temporary relief under section 105(b)(2) of the Mine Act from any modification or termination of any order issued thereunder, or from any order issued under section 104 of the Mine Act (other than citations issued under section 104(a) or (f) of the Mine Act).

•“29 CFR Part 2700, Subpart H” These legal actions include proceedings initiated under FMSHRC Procedural Rule 29 CFR Part 2700, Subpart H and are appeals of judges’ decisions or orders to FMSHRC, including petitions for discretionary review and review by FMSHRC on its own motion.

Organization, Consolidation and Presentation of Financial Statements [Abstract]

Business and Basis of Presentation

Business and Basis of Presentation

Description of the Business

Warrior Met Coal, Inc. (the "Company") is a U.S.-based environmentally and socially minded supplier to the global steel industry. The Company is dedicated entirely to mining non-thermal met coal used as a critical component of steel production by metal manufacturers in Europe, South America and Asia. The Company is a large-scale, low-cost producer and exporter of premium met coal, also known as hard-coking coal ("HCC"), operating highly efficient longwall operations in its underground mines based in Alabama. The HCC that the Company produces from the Blue Creek coal seam contains very low sulfur, has strong coking properties and is of a similar quality to coal referred to as premium HCC produced in Australia. The Company also generates ancillary revenues from the sale of natural gas extracted as a byproduct from the underground coal mines and royalty revenues from leased properties.

Basis of Presentation

The accompanying financial statements are presented in accordance with accounting principles generally accepted in the United States (“GAAP”) for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements. In our opinion, the financial statements include all adjustments (consisting of normal recurring accruals) necessary in order to make the financial statements not misleading. For further information, refer to the financial statements and related notes included in the Company's Annual Report on Form 10-K for the year ended December 31, 2022 (the "2022 Annual Report"). Operating results for the three and nine months ended September 30, 2023 are not necessarily indicative of the final results that may be expected for the year ended December 31, 2023. The balance sheet at December 31, 2022 has been derived from the audited financial statements for the year ended December 31, 2022 included in the 2022 Annual Report.

Collective Bargaining Agreement

The Company's Collective Bargaining Agreement ("CBA") with the labor union representing certain of the Company's hourly employees expired on April 1, 2021 and the labor union initiated a strike after an agreement on a new contract was not reached. As a result of the strike, the Company initially idled Mine No. 4 and scaled back operations at Mine No. 7. In the first quarter of 2022, the Company restarted operations at Mine No. 4. Due to the reduced operations at Mine No. 4 and Mine No. 7, the Company incurred idle mine expenses of $5.4 million and $10.1 million for the three and nine months ended September 30, 2022. The Company incurred no idle mine expenses for the three and nine months ended September 30, 2023. These expenses are reported separately in the Condensed Statements of Operations and represent expenses incurred, such as electricity, insurance and maintenance labor. The Company incurred business interruption expenses of approximately $0.3 million and $8.1 million for the three and nine months ended September 30, 2023, which represent ongoing legal expenses associated with ongoing labor negotiations. The Company incurred $7.1 million and $20.1 million for the three and nine months ended September 30, 2022, which represent non-recurring expenses that were directly attributable to the labor strike for incremental safety and security, labor negotiations and other expenses. These expenses are also presented separately in the Condensed Statements of Operations. On February 16, 2023, the labor union representing certain of the Company's hourly employees announced that they were ending the strike and made an unconditional offer to return to work. The return-to-work process for eligible employees who wished to return to work which began in February and has been completed. The Company continues to engage in good faith efforts with the labor union to reach an agreement on a new contract.

Acquisitions

On March 31, 2023, the Company acquired the remaining ownership interest in gas wells owned by an independent third party for $2.4 million. The purchase consideration has been preliminarily allocated to the assets acquired and liabilities assumed based upon their estimated fair values at the date of acquisition.

Accounting Policies [Abstract]

Summary of Significant Accounting Policies

Summary of Significant Accounting Policies

The Company's significant accounting policies are consistent with those disclosed in Note 2 to its audited financial statements included in the 2022 Annual Report.

Cash and Cash Equivalents

Cash and cash equivalents include short-term deposits and highly liquid investments that have original maturities of three months or less when purchased and are stated at cost, which approximates fair value.

Short-Term Investments

Instruments with maturities greater than three months, but less than twelve months, are included in short-term investments. The Company also purchases fixed income securities and certificates of deposits with varying maturities that are classified as available for sale and are carried at fair value. Securities classified as held to maturity are those securities that management has the intent and ability to hold to maturity.

As of September 30, 2023 and December 31, 2022, short-term investments consisted of $8.9 million and $8.6 million in cash and fixed income securities. The short-term investments are posted as collateral for the self-insured black lung related claims asserted by or on behalf of former employees of Walter Energy, Inc. ("Walter Energy") and its subsidiaries, which were assumed by the Company and relate to periods prior to March 31, 2016.

Revenue Recognition

    Revenue is recognized when performance obligations under the terms of a contract with the Company's customers are satisfied; for all contracts this occurs when control of the promised goods has been transferred to its customers. For coal shipments to domestic customers via rail, control is transferred when the railcar is loaded. For coal shipments to international customers via ocean vessel, control is transferred when the vessel is loaded at the Port of Mobile, Alabama. For natural gas sales, control is transferred when the gas has been transferred to the pipeline. Revenue is disaggregated between coal sales within the Company's mining segment and natural gas sales which is included in all other revenues, as disclosed in Note 13.

Since February 2017, the Company has had an arrangement with XCoal Energy & Resources ("XCoal") to serve as XCoal's strategic partner for exports of low-volatility HCC typically to the Asian region. Under this arrangement, XCoal takes title to and markets coal that the Company would historically have sold on the spot market, in an amount of the greater of (i) 10% of the Company's total production during the applicable term of the arrangement or (ii) 250,000 metric tons. During the three and nine months ended September 30, 2023 and 2022, XCoal accounted for approximately $36.7 million, or 7.3% and $126.8 million or 9.8% of total sales, and $69.8 million, or 20.6% and $281.3 million or 20.7% of total sales, respectively.

Trade Accounts Receivable and Allowance for Credit Losses

    Trade accounts receivable represent customer obligations that are derived from revenue recognized from contracts with customers. Credit is extended based on an evaluation of the individual customer's financial condition. The Company maintains trade credit insurance on the majority of its customers and the geographic regions of coal shipments to these customers. In some instances, the Company requires letters of credit, cash collateral or prepayments from its customers on or before shipment to mitigate the risk of loss. These efforts have consistently resulted in the Company recognizing no historical credit losses. The Company also has never had to have a claim against its trade credit insurance policy.

In order to estimate the allowance for credit losses on trade accounts receivable, the Company utilizes an aging approach in which potential impairment is calculated based on how long a receivable has been outstanding (e.g., current, 1-31 days, 31-60 days, etc.). The Company calculates an expected credit loss rate based on the Company’s historical credit loss rate, the risk characteristics of our customers, and the current met coal and steel market environments. As of September 30, 2023 and December 31, 2022, the estimated allowance for credit losses was immaterial and did not have a material impact on the Company's financial statements.

Income Tax Disclosure [Abstract]
Income Taxes	Income TaxesFor the three and nine months ended September 30, 2023 and 2022, the Company estimated its annual effective tax rate and applied this effective tax rate to its year-to-date pretax income at the end of the interim reporting period. The tax effect of unusual or infrequently occurring items, including the effects of changes in tax laws or rates and changes in judgment about the realizability of deferred tax assets, are reported in the interim period in which they occur. For the three and nine months ended September 30, 2023, the Company had income tax expense of $16.8 million and $60.4 million, respectively. The $16.8 million and $60.4 million income tax expense for the three and nine months ended September 30, 2023, includes a benefit related to depletion and Internal Revenue Code ("IRC") Section 250 Deduction: Foreign-Derived Intangible Income ("FDII"). The Tax Cuts and Jobs Act ("TCJA") was enacted on December 22, 2017 and enacted IRC Section 250 Deduction: FDII, which provides for, among other things, a deduction of 37.5% with respect to foreign-derived intangible income, which reduces the statutory tax rate from 21% to 13.125%. Beginning in 2026, the deduction is reduced from 37.5% to 22.5% of foreign-derived intangible income. The Company has historically not been eligible to claim the deduction due to the deduction being limited to taxable income and the Company's ability to utilize its net operating losses to offset taxable income.

Senior Secured Notes

On December 6, 2021, the Company issued $350.0 million in aggregate principal amount of 7.875% senior secured notes due 2028 (the “Notes”) at an initial price of 99.343% of their face amount. The Notes were issued to qualified institutional buyers pursuant to Rule 144A under the Securities Act of 1933, as amended (the “Securities Act”), and to certain non-U.S. persons in transactions outside the United States in accordance with Regulation S under the Securities Act. The Company used the net proceeds of the offering of the Notes, together with cash on hand, to fund the redemption of all of the Company’s outstanding 8.00% senior secured notes due 2024 (the “Existing Notes”), including payment of the redemption premium in connection with such redemption. The Notes will mature on December 1, 2028.

Concurrently with, but separate from, the Restricted Payment Offer, the Company commenced a cash tender offer (the “Tender Offer” and, together with the Restricted Payment Offer, the “Offers”) to purchase up to $150,000,000 principal amount of the Notes at a repurchase price of 104.25% of the aggregate principal amount of such Notes, plus accrued and unpaid interest to, but not including, the date of repurchase (the “TO Repurchase Price”). The Offers expired on September 7, 2023 (the “Expiration Date”).

Restricted Payment Offer

As of the Expiration Date, $200,000 aggregate principal amount of the Notes were validly tendered and not validly withdrawn pursuant to the Restricted Payment Offer. Pursuant to the terms of the Restricted Payment Offer:

(1) an automatic pro ration factor of 49.5674% was applied to the $200,000 aggregate principal amount of the Notes that were validly tendered and not validly withdrawn in the Restricted Payment Offer (rounded down to avoid the purchase of Notes in a principal amount other than in integrals of $1,000), which resulted in $99,000 aggregate principal amount of the Notes (the “RP Pro-Rated Tendered Notes”);

(2) the Company accepted all $99,000 aggregate principal amount of the RP Pro-Rated Tendered Notes for payment of the Restricted Payment Repurchase Price in cash; and

(3) the remaining balance of $101,000 aggregate principal amount of the Notes tendered that were not RP Pro-Rated Tendered Notes were not accepted for payment and were returned to the tendering holder of the Notes.

The Company consummated the Restricted Payment Offer on September 8, 2023.

Accordingly, pursuant to the terms of the Indenture, the Company will have the ability from time to time in the future to make one or more restricted payments (the "Proposed Restricted Payment") in the form of special dividends to holders of the Company’s common stock and/or repurchases of the Company’s common stock in the aggregate amount of up to $299,901,000 consistent with the terms of the Capital Allocation Policy adopted by the Company's board of directors (the "Board"). Any future Proposed Restricted Payments will be at the discretion of the Board and subject to a number of factors and there can be no assurance that the Company will make any Proposed Restricted Payments in the future.

Tender Offer

As of the Expiration Date, $294,770,000 aggregate principal amount of the Notes were validly tendered and not validly withdrawn pursuant to the Tender Offer. Pursuant to the terms of the Tender Offer:

(1) an automatic pro ration factor of 49.5674% was applied to the $294,770,000 aggregate principal amount of the Notes that were validly tendered and not validly withdrawn in the Tender Offer (rounded down to avoid the purchase of Notes in a principal amount other than in integrals of $1,000), which resulted in $146,002,000 aggregate principal amount of the Notes (the “TO Pro-Rated Tendered Notes”);

(2) the Company accepted all $146,002,000 aggregate principal amount of the TO Pro-Rated Tendered Notes for payment of the TO Repurchase Price in cash; and

(3) the remaining balance of $148,768,000 aggregate principal amount of the Notes tendered that were not TO Pro-Rated Tendered Notes were not accepted for payment and were returned to the tendering holder of the Notes.

The Second Amended and Restated Credit Agreement, among other things, (i) extended the maturity date of the ABL Facility to December 6, 2026; (ii) changed the calculation of the interest rate payable on borrowings from being based on a London Inter-Bank Offered Rate to be based on a SOFR, with corresponding changes to the applicable interest rate margins with respect to such borrowings, (iii) amended certain definitions related to the calculation of the borrowing base; (iv) increased the commitments that may be used to issue letters of credit to $65.0 million; and (v) amended certain baskets contained in the covenants to conform to the baskets contained in the indenture governing the Notes (the "Indenture"). The Second Amended and Restated Credit Agreement also allows the Company to borrow up to $132.0 million through October 13, 2023, decreasing to $116.0 million through November 2026, subject to availability under the borrowing base and other conditions.

Commitments and Contingencies

Environmental Matters

The Company is subject to a wide variety of laws and regulations concerning the protection of the environment, both with respect to the construction and operation of its plants, mines and other facilities and with respect to remediating environmental conditions that may exist at its own and other properties.

The Company believes it is in compliance with federal, state and local environmental laws and regulations. The Company accrues for environmental expenses resulting from existing conditions that relate to past operations when the costs are probable and can be reasonably estimated. As of September 30, 2023 and December 31, 2022, there were no accruals for environmental matters other than asset retirement obligations for mine reclamation.

Miscellaneous Litigation

From time to time, the Company is party to lawsuits arising in the ordinary course of business. The Company records costs relating to these matters when a loss is probable and the amount can be reasonably estimated. The effect of the outcome of these matters on the Company’s future results of operations cannot be predicted with certainty as any such effect depends on future results of operations and the amount and timing of the resolution of such matters. As of September 30, 2023 and December 31, 2022, there were no items accrued for miscellaneous litigation.

On July 15, 2015, Walter Energy and certain of its wholly owned U.S. subsidiaries, including Jim Walter Resources, Inc. (“JWR”) filed voluntary petitions for relief under chapter 11 of title 11 of the U.S. Bankruptcy Code (the “Chapter 11 Cases”) in the Northern District of Alabama, Southern Division. On December 7, 2015, Walter Energy Canada Holdings, Inc., Walter Canadian Coal Partnership and their Canadian affiliates (collectively “Walter Canada”) applied for and were granted protection under the Companies’ Creditors Arrangement Act (the “CCAA”) pursuant to an Initial Order of the Supreme Court of British Columbia. As a result of the Company’s acquisition of certain core operating assets of Walter Energy during the Chapter 11 Cases, in the first quarter of 2023 and 2022 the Company received $0.2 million and $0.7 million, respectively, from the Chapter 11 Cases which is reflected as other income in the Condensed Statement of Operations.

Other Commitments and Contingencies

The Company is party to various transportation and throughput agreements with rail and barge transportation providers and the Alabama State Port Authority. These agreements contain annual minimum tonnage guarantees with respect to coal transported from the mine sites to the Port of Mobile, Alabama, the unloading of rail cars or barges, and the loading of vessels. If the Company does not meet its minimum throughput obligations, which are based on annual minimum amounts, it is required to pay the transportation providers or the Alabama State Port Authority a contractually specified amount per metric ton for the difference between the actual throughput and the minimum throughput requirement. At September 30, 2023 and December 31, 2022, the Company had no liability recorded for minimum throughput requirements.

Royalty Obligations

A substantial amount of the coal that the Company mines is produced from mineral reserves leased from third-party landowners. These leases convey mining rights to the Company in exchange for royalties to be paid to the landowner as either a fixed amount per ton or as a percentage of the sales price. Although coal leases have varying renewal terms and conditions, they generally last for the economic life of the reserves. Coal royalty expenses were $29.3 million and $94.0 million and $42.4 million and $116.3 million for the three and nine months ended September 30, 2023 and 2022, respectively.

Common Shares

The Company is authorized to issue up to 140,000,000 common shares, $0.01 par value per share. Holders of common shares are entitled to receive dividends when authorized by the Board.

Stock Repurchase Program

On March 26, 2019, the Board approved the Company's second stock repurchase program (the “New Stock Repurchase Program”) that authorizes repurchases of up to an aggregate of $70.0 million of the Company's outstanding common stock. The Company fully exhausted its previous stock repurchase program (the "First Stock Repurchase Program") of $40.0 million of its outstanding common stock. The New Stock Repurchase Program does not require the Company to repurchase a specific number of shares or have an expiration date. The New Stock Repurchase Program may be suspended or discontinued by the Board at any time without prior notice.

    Under the New Stock Repurchase Program, the Company may repurchase shares of its common stock from time to time, in amounts, at prices and at such times as the Company deems appropriate, subject to market and industry conditions, share price, regulatory requirements and other considerations as determined from time to time by the Company. The Company’s repurchases may be executed using open market purchases or privately negotiated transactions in accordance with applicable securities laws and regulations, including Rule 10b-18 of the Exchange Act and repurchases may be executed pursuant to Rule 10b5-1 under the Exchange Act. Repurchases will be subject to limitations in the ABL Facility and the Indenture. The Company intends to fund repurchases under the New Stock Repurchase Program from cash on hand and/or other sources of liquidity. Any future repurchases of shares of the Company's common stock will be subject to the 1% excise tax under the Inflation Reduction Act of 2022 (“IRA”).

As of September 30, 2023 and December 31, 2022, the Company has repurchased 500,000 shares under the New Stock Repurchase Program for approximately $10.6 million, leaving approximately $59.4 million of share repurchases authorized under the New Stock Repurchase Program.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Instruments	Derivative InstrumentsThe Company enters into natural gas swap contracts from time to time to hedge the exposure to variability in expected future cash flows associated with the fluctuations in the price of natural gas related to the Company’s forecasted sales. As of September 30, 2023 and December 31, 2022, the Company had no natural gas swap contracts outstanding. The Company’s natural gas swap contracts economically hedge certain risks but are not designated as hedges for financial reporting purposes. All changes in the fair value of these derivative instruments are recorded as other revenues in the Condensed Statements of Operations. The Company recognized a gain related to natural gas swap contracts of $1.2 million, for the nine months ended September 30, 2023. The Company recognized no losses for the three months ended September 30, 2023 and September 30, 2022 and recognized $27.7 million for the nine months ended September 30, 2022. The Company records all derivative instruments at fair value and had no asset or liability recorded as of September 30, 2023 and December 31, 2022.

Fair Value Disclosures [Abstract]

Fair Value of Financial Instruments

Fair Value of Financial Instruments

The Company had no significant assets or any other liabilities measured at fair value on a recurring basis as of September 30, 2023 or December 31, 2022. During the nine months ended September 30, 2023, there were no transfers between Level 1, Level 2 and Level 3. The Company uses quoted dealer prices for similar contracts in active over-the-counter markets for determining fair value of Level 2 liabilities. There were no changes to the valuation techniques used to measure liability fair values on a recurring basis during the nine months ended September 30, 2023.

The following methods and assumptions were used to estimate the fair value for which the fair value option was not elected:

Cash and cash equivalents, short-term investments, receivables and trade accounts payable — The carrying amounts reported in the Condensed Balance Sheets approximate fair value due to the short-term nature of these assets and liabilities.

Debt — The Company's outstanding debt is carried at cost. As of September 30, 2023, there were no borrowings outstanding under the ABL Facility, with $123.3 million available, net of outstanding letters of credit of $8.7 million. As of December 31, 2022, the Company had no borrowings outstanding under the ABL Facility, with $123.3 million available, net of outstanding letters of credit of $8.7 million. As of September 30, 2023 and December 31, 2022, the estimated fair value of the Notes based upon observable market data (Level 2) was approximately $156.9 million and $304.4 million, respectively.

Segment Reporting [Abstract]

Segment Information

Segment Information

The Company identifies a business as an operating segment if: (i) it engages in business activities from which it may earn revenues and incur expenses; (ii) its operating results are regularly reviewed by the Chief Operating Decision Maker (“CODM”), who is the Company’s Chief Executive Officer, to make decisions about resources to be allocated to the segment and assess its performance; and (iii) it has available discrete financial information. The Company has determined that its two underground mining operations are its operating segments. The CODM reviews financial information at the operating segment level to allocate resources and to assess the operating results and financial performance for each operating segment. Operating segments are aggregated into a reportable segment if the operating segments have similar quantitative economic characteristics and if the operating segments are similar in the following qualitative characteristics: (i) nature of products and services; (ii) nature of production processes; (iii) type or class of customer for their products and services; (iv) methods used to distribute the products or provide services; and (v) if applicable, the nature of the regulatory environment.

The Company has determined that the two operating segments are similar in both quantitative and qualitative characteristics and thus the two operating segments have been aggregated into one reportable segment. The Company has determined that its natural gas and royalty businesses and the Blue Creek mine development did not meet the criteria in ASC 280 to be considered as operating or reportable segments. Therefore, the Company has included their results in an “all other” category as a reconciling item to consolidated amounts.

The Company does not allocate all of its assets, or its depreciation and depletion expense, selling, general and administrative expenses, transactions costs, interest income (expense), and income tax expense or benefit by segment.

The following tables include reconciliations of segment information to consolidated amounts (in thousands):

The Company evaluates the performance of its segment based on Segment Adjusted EBITDA, which is defined as net income adjusted for other revenues, cost of other revenues, depreciation and depletion, selling, general and administrative, business interruption, idle mine, other income, interest income (expense), net, income tax expense, loss on extinguishment of debt and certain transactions or adjustments that the CODM does not consider for the purposes of making decisions to allocate resources among segments or assessing segment performance. Segment Adjusted EBITDA does not represent and should not be considered as an alternative to cost of sales under GAAP and may not be comparable to other similarly titled measures used by other companies.

Summary of Significant Accounting Policies (Policies)

9 Months Ended

Sep. 30, 2023

Accounting Policies [Abstract]

Basis of Presentation

Basis of PresentationThe accompanying financial statements are presented in accordance with accounting principles generally accepted in the United States (“GAAP”) for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements. In our opinion, the financial statements include all adjustments (consisting of normal recurring accruals) necessary in order to make the financial statements not misleading.

Cash and Cash Equivalents

Cash and Cash Equivalents Cash and cash equivalents include short-term deposits and highly liquid investments that have original maturities of three months or less when purchased and are stated at cost, which approximates fair value.

Short-Term Investments

Short-Term Investments

Instruments with maturities greater than three months, but less than twelve months, are included in short-term investments. The Company also purchases fixed income securities and certificates of deposits with varying maturities that are classified as available for sale and are carried at fair value. Securities classified as held to maturity are those securities that management has the intent and ability to hold to maturity.

Revenue Recognition

Revenue Recognition    Revenue is recognized when performance obligations under the terms of a contract with the Company's customers are satisfied; for all contracts this occurs when control of the promised goods has been transferred to its customers. For coal shipments to domestic customers via rail, control is transferred when the railcar is loaded. For coal shipments to international customers via ocean vessel, control is transferred when the vessel is loaded at the Port of Mobile, Alabama. For natural gas sales, control is transferred when the gas has been transferred to the pipeline. Revenue is disaggregated between coal sales within the Company's mining segment and natural gas sales which is included in all other revenues, as disclosed in Note 13.

Trade Accounts Receivable and Allowance for Credit Losses

Trade Accounts Receivable and Allowance for Credit Losses

    Trade accounts receivable represent customer obligations that are derived from revenue recognized from contracts with customers. Credit is extended based on an evaluation of the individual customer's financial condition. The Company maintains trade credit insurance on the majority of its customers and the geographic regions of coal shipments to these customers. In some instances, the Company requires letters of credit, cash collateral or prepayments from its customers on or before shipment to mitigate the risk of loss. These efforts have consistently resulted in the Company recognizing no historical credit losses. The Company also has never had to have a claim against its trade credit insurance policy.

In order to estimate the allowance for credit losses on trade accounts receivable, the Company utilizes an aging approach in which potential impairment is calculated based on how long a receivable has been outstanding (e.g., current, 1-31 days, 31-60 days, etc.). The Company calculates an expected credit loss rate based on the Company’s historical credit loss rate, the risk characteristics of our customers, and the current met coal and steel market environments. As of September 30, 2023 and December 31, 2022, the estimated allowance for credit losses was immaterial and did not have a material impact on the Company's financial statements.
