FORWARD-LOOKING STATEMENTS

This Quarterly Report on Form 10-Q (this "Form 10-Q") 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. 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:

• successful implementation of our business strategies;

• a substantial or extended decline in pricing or demand for metallurgical ("met") coal;

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

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

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

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

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

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

• competition and foreign currency fluctuations;

• our ability to comply with covenants in our asset-based revolving credit facility (as amended and restated, the "ABL Facility") and the Indenture (as defined below);

• our substantial indebtedness and debt service requirements;

• 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;

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

• any consequences related to our transfer restrictions under our certificate of incorporation;

• our obligations surrounding reclamation and mine closure;

• inaccuracies in our estimates of our met coal reserves;

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

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

• challenges to our licenses, permits and other authorizations;

1

• 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;

• costs associated with our pension and benefits, including post-retirement benefits;

• costs associated with our workers’ compensation benefits;

• litigation, including claims not yet asserted;

• 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; and

• terrorist attacks or security threats, including cybersecurity threats.

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 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

THREE MONTHS ENDED MARCH 31, 2019 (UNAUDITED)

Note 1—Business and Basis of Presentation

Description of the Business

Warrior Met Coal, Inc. (the "Company") is a U.S. based producer and exporter of met coal for a diversified customer base of blast furnace steel producers located primarily in Europe, South America and Asia. 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 generally accepted accounting principles 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 consolidated financial statements and related notes included in the Company's Annual Report on Form 10-K for the year ended December 31, 2018. Operating results for the three months ended March 31, 2019 and March 31, 2018 are not necessarily indicative of the final results that may be expected for the year ended December 31, 2019. The balance sheet at December 31, 2018 has been derived from the audited financial statements for the year ended December 31, 2018 included in the Company's Annual Report on Form 10-K for the year ended December 31, 2018 (the "2018 Annual Report").

Note 2—Summary of Significant Accounting Policies

Our significant accounting policies are consistent with those disclosed in Note 2 to our audited financial statements included in the 2018 Annual Report, except for changes related to new accounting pronouncements described in "New Accounting Pronouncements".

Cash and Cash Equivalents and Restricted Cash

The following table provides a reconciliation of cash and cash equivalents and restricted cash reported within the Condensed Balance Sheets that sum to the total of the same such amounts shown in the Condensed Statements of Cash Flows (in thousands):

	March 31, 2019		December 31, 2018
Cash and cash equivalents	$	154,912	$	205,577
Restricted cash included in other long-term assets	830		828
Total cash and cash equivalents and restricted cash included in the Condensed Statements of Cash Flows	$	155,742	$	206,405

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. As of March 31, 2019 and December 31, 2018, restricted cash included in other long-term assets in the Condensed Balance Sheets represents amounts invested in certificates of deposits as financial assurance for post mining reclamation obligations.

Short-Term Investments

Instruments with maturities greater than three months, but less than twelve months, are included in short-term investments. The Company purchases United States Treasury ("Treasury") bills with maturities ranging from six to twelve months which are classified as held to maturity and are carried at amortized cost, which approximates fair value. Securities classified as held to maturity are those securities that management has the intent and ability to hold to maturity.

WARRIOR MET COAL, INC.

NOTES TO CONDENSED FINANCIAL STATEMENTS (Continued)

THREE MONTHS ENDED MARCH 31, 2019 (UNAUDITED)

As of March 31, 2019 and December 31, 2018, the Company’s short-term investments consisted of $17.5 million in Treasury bills with a maturity of six months. These Treasury bills were posted as collateral for the self-insured black lung related claims asserted by or on behalf of former employees of Walter Energy, Inc. 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 our customers are satisfied; for all contracts this occurs when control of the promised goods have been transferred to our 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 included in all other revenues, as disclosed in Note 14.

Since February 2017, we have had an arrangement with XCoal Energy & Resource ("XCoal") to serve as XCoal's strategic partner for exports of low-volatility HCC. Under this arrangement, XCoal takes title to and markets coal that we would historically have sold on the spot market, in an amount of the greater of (i) 10% of our total production during the applicable term of the arrangement or (ii) 250,000 metric tons. During the three months ended March 31,2019 and 2018, XCoal accounted for approximately $94.9 million, or 25.8% of total revenues, and $86.2 million, or 20.8% of total revenues, respectively.

New Accounting Pronouncements

The Company adopted Accounting Standards Update (“ASU”) No. 2016-02, "Leases (Topic 842)" as of January 1, 2019 using the modified retrospective approach (the "New Leases Standard"). The New Leases Standard requires a lessee to recognize a right-of-use asset and lease liability on its balance sheet for all leases. The Company has chosen to use its adoption date as its date of initial application. As a result, financial information will not be updated and the disclosures required under the new standard will not be provided for dates and periods before January 1, 2019.

The Company made an accounting policy election that leases with an initial term of 12 months or less will remain off of its balance sheet and lease payments will instead be recognized in the Condensed Statements of Operations on a straight-line basis over the lease term. Additionally, the Company elected the package of practical expedients for all leases, which permits the Company to forego reassessing expired or existing contracts to determine: whether they are or contain leases, lease classification, and initial direct costs. Management elected the optional transition expedient which allows the Company to continue applying the current policy for accounting for expired or existing land easement contracts that were not previously accounted for under GAAP. New or modified land easements executed after adoption will be considered under the New Lease Standard. The Company elected the practical expedient as an accounting policy election for all asset classifications, which allows it to account for them as a single lease component, rather than as separate lease and non-lease components.

As the Company’s historical operating leases are primarily short term rental agreements of less than one year, the Company did not record any additional lease assets or lease liabilities upon adoption of the New Leases Standard. The New Leases Standard did not impact the Company's balance sheet or consolidated net income and had no impact on cash flows. As of March 31, 2019, the Company has a right-of-use asset of $5.8 million, net of accumulated amortization, and a liability of $6.9 million.

On August 17, 2018, the SEC adopted a final rule that eliminates or amends certain disclosure requirements that were deemed redundant and outdated in light of changes in SEC requirements, U.S. GAAP or changes in technology or the business environment. The rule also requires registrants to include in their interim financial statements a reconciliation of changes in stockholders’ equity in the notes or as a separate statement. The analysis should reconcile the beginning balance to the ending balance of each caption in shareholders’ equity for each period for which an income statement is required to be filed. The final rule became effective November 5, 2018. Beginning in the first quarter of fiscal 2019, we have provided a reconciliation for the quarterly period as well as the comparable prior period in this Form 10-Q. The eliminated or amended disclosures did not have a material impact on the Company’s unaudited condensed financial statements.

Total inventories, net	$	70,356	$	56,719

Note 4—Income Taxes

For the three months ended March 31, 2019, 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 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.

The Company had income tax expense of $28.0 million for the three months ended March 31, 2019. The Company had no income tax expense for the three months ended March 31, 2018 due to the utilization of NOLs to offset taxable income for which a full valuation allowance was recorded. As a result of various favorable factors further discussed in the 2018 Annual Report, the Company released its valuation allowance against its net deferred income tax assets in the fourth quarter of 2018.

The Notes mature on November 1, 2024 and interest is payable on May 1 and November 1 of each year.

Offers to Purchase the Notes

On February 21, 2019, 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 March 22, 2019 (the “Expiration Date”).

Restricted Payment Offer

As of the Expiration Date, $1,900,000 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 31.5789% was applied to the $1,900,000 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 $599,000 aggregate principal amount of the Notes (the “RP Pro-Rated Tendered Notes”);

(2) the Company accepted all $599,000 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 $1,301,000 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 March 25, 2019.

Accordingly, pursuant to the terms of the Indenture, the Company was permitted to make one or more restricted payments 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 $299,401,000 (the "RP Basket") without having to make another offer to repurchase Notes. The Company intends to use the RP Basket to pay the April 2019 Special Dividend (as defined below) and make repurchases under the New Stock Repurchase Program (as defined below).

Tender Offer

As of the Expiration Date, $415,099,000 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 31.5789% was applied to the $415,099,000 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 $130,966,000 aggregate principal amount of the Notes (the “TO Pro-Rated Tendered Notes”);

2017 Equity Plan

On February 8, 2019, the Company awarded 306,314 restricted stock unit awards under the Company's 2017 Equity Incentive Plan (the "2017 Equity Plan"). These awards have certain service-based, performance-based and market-based vesting conditions, as applicable. The service-based awards vest over a period of three years and the performance-based and market-based awards are based on the Company's performance in each of the three years. The Company recognized approximately $0.5 million in stock compensation expense associated with these awards for the three months ended March 31, 2019.

Additionally, the Company awarded $1.5 million of restricted stock unit awards under the 2017 Equity Plan that can be settled in shares or in cash at the election of employees. These awards have certain service-based and performance-based vesting conditions and can be earned no later than December 31, 2021. If the Company were to settle these awards in shares these awards would represent 49,342 shares based on the Company's closing share price on March 31, 2019. The Company recognized approximately $86 thousand in stock compensation expense associated with these awards for the three months ended March 31, 2019.

As of March 31, 2019, there were 157,124 restricted stock unit awards for which the service-based vesting conditions for these awards were not met as of the measurement date. As such, these awards were excluded from basic earnings per share. These awards had a 28,302 share impact on dilutive weighted average shares. As of March 31, 2019, there were 280,492 restricted stock unit awards for which the performance-based and market-based vesting conditions were not met as of the measurement date and, as such, these awards were excluded from basic and diluted earnings per share. For the 49,342 restricted stock unit awards classified as a liability, the Company considered the impact on diluted earnings as if the award was settled in cash or in shares. As the impact of these shares is anti-dilutive, they have been excluded from both basic and diluted earnings per share.

As of March 31, 2019, there were 43,580 shares of our common stock contingently issuable upon the settlement of a vested phantom unit award granted under our 2016 Equity Plan (as defined below) and 13,157 shares of our common stock contingently issuable upon the settlement of a vested restricted stock unit award under our 2017 Equity Plan, as applicable. The settlement date for these awards is the earlier of a change in control as described in our 2016 Equity Plan or 2017 Equity Plan, as applicable, or five years from the grant date. These awards are vested and, as such, have been included in the weighted average shares used to compute basic and diluted net income per share.

2016 Equity Plan

As of March 31, 2019, there were 124,307 restricted stock unit awards granted under the Company's 2016 Equity Incentive Plan (the "2016 Equity Plan") to certain directors and employees, for which the service-based vesting conditions for these awards were not met as of the measurement date. As such, these awards were excluded from basic earnings per share. These awards had an 90,419 share impact on dilutive weighted average shares.

Note 9—Related Party Transactions

The Company owns a 50% interest in Black Warrior Methane (“BWM”) and Black Warrior Transmission (“BWT”), which are accounted for under the proportionate consolidation method and equity method, respectively. The Company has granted the rights to produce and sell methane gas from its coal mines to BWM and BWT. The Company’s net investments in, advances to/from BWT and equity in earnings or loss of BWT are not material to the Company. The Company supplied labor to BWM and incurred costs, including property and liability insurance, to support the joint venture. The Company charged the joint venture for such costs on a monthly basis, which were $0.1 million for the three months ended March 31, 2019 and $0.8 million for the three months ended March 31, 2018.

Note 10—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 that it is in substantial 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 March 31, 2019 and December 31, 2018, 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 a number of lawsuits arising in the ordinary course of their businesses. 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 March 31, 2019 and December 31, 2018, there were no items accrued for miscellaneous litigation.

Commitments and Contingencies—Other

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 March 31, 2019 and December 31, 2018, 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 land owners. These leases convey mining rights to the Company in exchange for royalties to be paid to the land owner 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 expense was $26.7 million for the three months ended March 31, 2019 and $22.3 million for the three months ended March 31, 2018.

New Stock Repurchase Program

On March 26, 2019, the Company's board of directors (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 as determined from time to time by the Company and other considerations. 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.

Note 12—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 March 31, 2019, the Company had no natural gas swap contracts outstanding. As of December 31, 2018, the Company had natural gas swap contracts outstanding with notional amounts totaling 2,100 million British thermal units maturing in the first quarter of 2019.

The Company’s 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. The Company records all derivative instruments at fair value and had no liability as of March 31, 2019 and a liability of $0.2 million as of December 31, 2018 included in other current liabilities in the accompanying Condensed Balance Sheets.

Note 13—Fair Value of Financial Instruments

The Company had no assets or any other liabilities measured at fair value on a recurring basis as of March 31, 2019. The following table presents information about the Company’s financial liabilities measured at fair value on a recurring basis as of December 31, 2018 and indicates the level of the fair value hierarchy utilized to determine such fair value (in thousands):

As of March 31, 2019, there were no borrowings outstanding under the ABL Facility, with $120.4 million available, net of outstanding letters of credit of $4.6 million. There were no borrowings outstanding under the ABL Facility and there were $4.6 million of letters of credit issued and outstanding under the ABL Facility as of December 31, 2018. The estimated fair value of the Notes is approximately $358.9 million based upon observable market data (Level 2).

Note 14—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 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 expense, and income tax expense by segment.

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

	For the three months ended March 31,

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 months ended March 31, 2019 and March 31, 2018. 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, 2018 included in the Company's Annual Report on Form 10-K for the year ended December 31, 2018 (the "2018 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 large scale, low cost U.S.-based producer and exporter of premium met coal operating two highly productive underground mines in Alabama.

As of December 31, 2018, Mine No. 4 and Mine No. 7, our two operating mines, had approximately 108.3 million metric tons of recoverable reserves and our undeveloped Blue Creek Energy Mine ("Blue Creek") contained 103.0 million metric tons of recoverable reserves. Our hard coking coal (“HCC”), mined from the Southern Appalachian region of the United States, is characterized by low-to-medium volatile matter (“VM”) and high coke strength after reaction (“CSR”). These qualities make our coal ideally suited as a coking coal for the manufacture of steel. As a result of our high quality coal, our realized price has historically approximated the Platts Premium Low Volatility ("LV") Free-On-Board ("FOB") Australia Index Price (the "Platts Index"). Coal from Mine No. 7 is classified as a premium LV HCC and coal from Mine No. 4 is classified as premium LV to mid-volatility ("MV") HCC. In contrast, coal produced in the Central Appalachian region of the United States is typically characterized by medium-to-high VM and a CSR that is below the requirements of the Platts Index.

We sell substantially all of our met coal production to steel producers. Met coal, which is converted to coke, is a critical input in the steel production process. Met 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 met 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 met coal, which would have a material adverse effect upon our business. Similarly, if alternative ingredients are used in substitution for met coal in the integrated steel mill process, the demand for met coal would materially decrease, which could also materially adversely affect demand for our met coal.

How We Evaluate Our Operations

Our primary business, the mining and exporting of met coal for the steel industry, is conducted in one 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, a non-GAAP (as defined below) financial measure; (ii) sales volumes and average 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.

⁽¹⁾ For the three months ended March 31, 2019 and 2018, our gross price realization represents a volume weighted-average calculation of our daily realized price per ton based on gross sales, which excludes demurrage and other charges, as a percentage of the Platts Index price.

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, 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, Gross Price Realization 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 coal. Our sales volume and sales prices are largely dependent upon the terms of our annual coal sales contracts, for which prices generally are set on daily index averages or a quarterly basis. The volume of 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 coal on two primary metrics: first, our gross price realization and second, our average net selling price per metric ton.

In the first quarter of 2018, we changed our gross price realization calculation to no longer be based on the quarterly Australian LV Index average due to this index being on a one-month lag basis and not closely correlating with the timing of our shipments. Our gross price realization now represents a volume weighted-average calculation of our daily realized price per ton based on the blended gross sales of our LV and MV coal, excluding demurrage and quality specification adjustments, as a percentage of the Platts Index daily price. Our gross price realizations reflect the premiums and discounts we achieve on our LV and MV coal versus the Platts Index price because of the high quality premium products we sell into the export markets. In addition, the premiums and discounts in a quarter or year can be impacted by a rising or falling price environment.

On a quarterly basis, our blended gross selling price per metric ton may differ from the Platts Index price per metric ton, primarily due to our gross sales price per ton being based on a blended average of gross sales price on our LV and MV coals as compared to the Platts Index price and due to the fact that many of our met coal supply agreements are based on a variety of indices.

20

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 the previously mentioned 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 free-on-board at the Port of Mobile. 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

• 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 costs 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 free-on-board at the Port of Mobile. 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.

	For the three months ended March 31,
	2019			2018

Cost of sales	$	182,628		$	190,676
Asset retirement obligation accretion	(373		)	(560		)
Stock compensation expense	(319		)	(67		)
Cash cost of sales	$	181,936		$	190,049

Adjusted EBITDA

We define Adjusted EBITDA as net income before net interest expense, income tax expense, depreciation and depletion, non-cash stock compensation expense, non-cash asset retirement obligation accretion, transaction and other expenses and loss on early extinguishment of debt. 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.

21

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 loss or any other measure of financial performance or liquidity presented in accordance with GAAP. Adjustments excludes some, but not all, items that affect net loss 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 for the three months ended March 31, 2019 and 2018 were as follows:

	For the three months ended March 31,
	2019			2018

Average selling price per metric ton	$	194.47		$	215.04
Cash cost of sales per metric ton	$	95.71		$	98.98

⁽¹⁾ For the three months ended March 31, 2019 and 2018, our gross price realization represents a volume weighted-average calculation of our daily realized price per ton based on gross sales, which excludes demurrage and other charges, as a percentage of the Platts Index price.

Sales for the three months ended March 31, 2019 were $369.7 million compared to $412.9 million for the three months ended March 31, 2018. The $43.2 million decrease in revenues was primarily driven by a $39.2 million decrease in revenue related to a $20.57 decrease in the average selling price per metric ton of met coal and a $4.1 million decrease in revenue due to a 19 thousand metric ton decrease in met coal sales volume.

23

For the three months ended March 31, 2019, our geographic customer mix was 53% in Europe, 26% in Asia and 21% in South America. For the three months ended March 31, 2018, our geographic customer mix was 49% in Europe, 27% in South America and 24% in Asia. Our geographic customer mix typically varies each period based on the timing of customer orders and shipments. There have been no significant changes in our customer base for the three months ended March 31, 2019.

Other revenues for the three months ended March 31, 2019 were $8.6 million compared to $8.9 million for the three months ended March 31, 2018. Other revenues are comprised of revenue derived from our natural gas operations, as well as earned royalty revenue. The $0.3 million decrease in other revenues is primarily due to a decrease in earned royalty revenue. Cost of other revenues remained consistent for the period.

Cost of sales (exclusive of items shown separately below) was $182.6 million, or 48.3% of total revenues, for the three months ended March 31, 2019, compared to $190.7 million, or 45.2% of total revenues for the three months ended March 31, 2018. The $8.0 million decrease is primarily driven by a $6.0 million decrease due to a $3.27 decrease in average cash cost of sales per metric ton and $1.9 million decrease related to a decrease in met coal sales volumes of 19 thousand metric tons. The decrease in cash cost of sales per metric ton is primarily due to decreased supply spend and royalty costs due to a lower average selling price per metric ton in the first quarter of 2019 compared to the first quarter of 2018.

Depreciation and depletion was $22.2 million, or 5.9% of total revenues, for the three months ended March 31, 2019, compared to $24.6 million, or 5.8% for the three months ended March 31, 2018. The $2.3 million decrease was driven primarily by a 19 thousand metric ton decrease in met coal sales volumes combined with an increase in met coal production offset partially by an increase in depletion due to an increase in metric tons produced.

Selling, general and administrative expenses were $8.9 million, or 2.4% of total revenues, for the three months ended March 31, 2019, compared to $8.2 million, or 2.0% of total revenues, for the three months ended March 31, 2018. The $0.7 million increase is driven primarily by an increase in stock compensation expense.

There were no transaction and other expenses for the three months ended March 31, 2019 compared to $3.3 million for the three months ended March 31, 2018, which was comprised primarily of professional fees incurred in connection with the issuance of the New Notes (defined below).

Interest expense, net was $8.6 million, or 2.3% of total revenues, for the three months ended March 31, 2019, compared to $8.6 million, or 2.0% of total revenues, for the three months ended March 31, 2018. Interest expense, net is comprised of interest on our Notes (as defined below), security agreement and promissory note, and amortization of debt issuance costs related to the ABL Facility and Notes.

For the three months ended March 31, 2019, we recognized a loss on early extinguishment of debt of 9.8 million upon the extinguishment of $131.6 million of our Notes. The loss on early extinguishment of debt represents a premium paid to retire the debt, accelerated amortization of debt discount, net, and fees incurred in connection with the transaction.

For the three months ended March 31, 2019, we recognized income tax expense of $28.0 million. For the three months ended March 31, 2018 we did not have any income tax expense due to the utilization of our NOLs to offset taxable income for which a full valuation allowance was recorded. As a result of various favorable factors further discussed in the 2018 Annual Report, the Company released its valuation allowance against its net deferred income tax assets in the fourth quarter of 2018.

Liquidity and Capital Resources

Overview

Our sources of cash have been coal and natural gas sales to customers, proceeds received from the issuance of 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, 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 have used available cash on hand to repurchase shares of our common stock, pay quarterly dividends, and pay special dividends, each of which reduces cash and cash equivalents.

Going forward, we will use cash to fund debt service payments on our Notes and our other indebtedness, to fund operating activities, working capital, capital expenditures, and strategic investments, and, if declared, to pay our quarterly and/

24

or special dividends. Our ability to fund our capital needs 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 expenditures, or special dividends financed partially or wholly with debt financing, our ability to access the capital markets to raise additional capital. We believe that our future cash flow from operations, together with cash on our balance sheet and borrowing availability under our ABL Facility, will provide adequate resources to fund our debt service payments and planned operating and capital expenditure needs for at least the next twelve months.

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. Although we believe we can currently finance our operations on acceptable terms and conditions, 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 (as defined below), 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.

Our available liquidity as of March 31, 2019 was $275.3 million, consisting of cash and cash equivalents of $154.9 million and $120.4 million available under our ABL Facility. As of March 31, 2019, there were no borrowings outstanding under the ABL Facility, with $120.4 million available, net of outstanding letters of credit of $4.6 million. For the three months ended March 31, 2019, cash flows provided by operating activities were $126.4 million, cash flows used in investing activities were $29.7 million and cash flows used in financing activities were $147.3 million.

Statements of Cash Flows

Cash balances were $154.9 million and $205.6 million at March 31, 2019 and December 31, 2018, 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 March 31
	2019			2018
Net cash provided by operating activities	$	126,408		$	193,738
Net cash used in investing activities	(29,739		)	(22,542		)
Net cash (used in) provided by financing activities	(147,332		)	115,392
Net increase (decrease) in cash and cash equivalents and restricted cash	$	(50,663	)	$	286,588

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 benefit, stock-based compensation, amortization of debt issuance costs and debt discount/premium, accretion of asset retirement obligations, loss on early extinguishment of debt and changes in net working capital. The timing between the conversion of our billed and unbilled receivables into cash from our customers and disbursements to our vendors is the primary driver of changes in our working capital.

Net cash provided by operating activities was $126.4 million for the three months ended March 31, 2019, and was primarily attributed to net income of $110.4 million adjusted for income tax expense of $28.0 million, depreciation and depletion expense of $22.2 million, loss on early extinguishment of debt of $9.8 million, stock based compensation expense of $1.2 million, amortization of debt issuance costs and debt discount/premium of $0.4 million and accretion of asset retirement obligations of $0.8 million, coupled with a net increase in our working capital of $49.2 million. The increase in our working capital was primarily driven by an increase in trade accounts receivable and inventories coupled with a decrease in accrued expenses and other current liabilities offset partially by an increase in accounts payable and prepaid expenses. The increase in our accounts receivable and inventory was primarily driven by an increase in metric tons sold and produced and the decrease in accrued expenses and other current liabilities was due to the payment of employee bonuses in the first quarter of 2019.

25

Net cash provided by operating activities was $193.7 million for the three months ended March 31, 2018 and was primarily attributed to net income of $178.7 million adjusted for depreciation and depletion expense of $24.6 million, stock based compensation expense of $0.2 million , amortization of debt issuance costs and debt discount/premium of $0.6 million and accretion of asset retirement obligations of $1.2 million, offset by a net increase in our working capital of $9.0 million. The increase in our working capital was primarily driven by an increase in trade accounts receivables offset partially by a decrease in prepaid expenses, accrued expenses and other current liabilities, accounts payable, other receivables and inventories. The increase in our accounts receivable is primarily driven by an increase in metric tons sold offset partially by a decrease in the average selling price per metric ton.

Investing Activities

Net cash used in investing activities was $29.7 million and $22.5 million for the three months ended March 31, 2019 and March 31, 2018, respectively, primarily due to purchases of property, plant and equipment and Mine 4 mine development.

Financing Activities

Net cash used in financing activities was $147.3 million for the three months ended March 31, 2019, primarily due to the retirement of debt of $140.3 million, payment of dividends of $2.6 million, common shares repurchased of $2.0 million, and principal repayments of capital lease obligations of $2.0 million. Net cash provided by financing activities was $115.4 million for the three months ended March 31, 2018, primarily due to the proceeds received from the New Notes (defined below) of $126.9 million offset by our quarterly dividend of $2.7 million and debt issuance costs of $3.7 million.

Stock Repurchase Program

On March 26, 2019, our board of directors (the "Board") approved our second stock repurchase program (the “New Stock Repurchase Program”) that authorizes repurchases of up to an aggregate of $70.0 million of our outstanding common stock. We fully exhausted our previous stock repurchase program (the "First Stock Repurchase Program") of $40.0 million of our outstanding common stock. The New Stock Repurchase Program does not require us 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, we may repurchase shares of our common stock from time to time, in amounts, at prices and at such times as we deem appropriate, subject to market and industry conditions, share price, regulatory requirements as determined from time to time by us and other considerations. Our 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. We intend to fund repurchases under the New Stock Repurchase Program from cash on hand and/or other sources of liquidity.

Dividend Policy

On May 17, 2017, the Board adopted a dividend policy (the "Dividend Policy") of paying a quarterly cash dividend of $0.05 per share. The Dividend Policy also states the following: In addition to the regular quarterly dividend and to the extent that we generate 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 repurchase of common stock pursuant to 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. We will also seek to optimize its capital structure to improve returns to stockholders while allowing flexibility for us to pursue very selective strategic growth opportunities that can provide compelling stockholder returns.

On April 23, 2019, the Board declared a regular quarterly cash dividend of $0.05 per share, totaling approximately $2.6 million, which will be paid on May 10, 2019 to stockholders of record as of the close of business on May 3, 2019.

On February 19, 2019, the Board declared a regular quarterly cash dividend of $0.05 per share, totaling $2.6 million, which was paid on March 11, 2019, to stockholders of record as of the close of business on March 4, 2019.

On April 24, 2018, the Board declared a regular quarterly cash dividend of $0.05 per share, totaling approximately $2.7 million, which was paid on May 11, 2018, to stockholders of record as of the close of business on May 4, 2018.

26

On February 13, 2018, the Board declared a regular quarterly cash dividend of $0.05 per share, totaling $2.7 million, which was paid on March 2, 2018, to stockholders of record as of the close of business on February 23, 2018.

April 2019 Special Dividend

On April 23, 2019, the Board declared a special cash dividend (the "April 2019 Special Dividend") of approximately $230.0 million, which will be paid on May 14, 2019 to stockholders of record as of the close of business on May 6, 2019. We intend to fund the April 2019 Special Dividend with cash on hand.

April 2018 Special Dividend

On April 3, 2018, the Board declared the April 2018 Special Dividend of approximately $350.0 million, which was funded with the net proceeds from the offering of the New Notes due 2024, together with cash on hand of approximately $225.0 million, and was paid on April 20, 2018 to stockholders of record as of the close of business on April 13, 2018.

ABL Facility

The ABL Facility will mature on October 15, 2023. As of March 31, 2019, no amounts were outstanding under the ABL Facility and there were $4.6 million of outstanding letters of credit. At March 31, 2019, we had $120.4 million of availability under the ABL Facility.

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 March 31, 2019, 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 March 31, 2019.

Senior Secured Notes

On November 2, 2017, we issued $350.0 million aggregate principal amount of our 8.00% Senior Secured Notes due 2024 (the "Original Notes"). We then issued an additional $125.0 million in aggregate principal amount of our 8.00% Senior Secured Notes due 2024 (the “New Notes” and, together with the Original Notes, the "Notes") on March 1, 2018. The New Notes were issued as "Additional Notes" under the indenture dated as of November 2, 2017 (the "Original Indenture"), among us, the subsidiary guarantors party thereto and Wilmington Trust, National Association, as trustee and priority lien collateral trustee, as supplemented by the First Supplemental Indenture, dated as of March 1, 2018 (the "First Supplemental Indenture" and, the Original Indenture as supplemented thereby and by the Second Supplemental Indenture, dated as of March 2, 2018, the "Indenture"). The Notes mature on November 1, 2024 and interest is payable on May 1 and November 1 of each year.

Offers to Purchase the Notes

On February 21, 2019, we commenced an offer to purchase (the “Restricted Payment Offer”), in cash, up to $150,000,000 principal amount of our 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 at 5:00 P.M., New York City time, on March 22, 2019 (such date and time, the “Expiration Date”).

27

Restricted Payment Offer

As of the Expiration Date, $1,900,000 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 31.5789% was applied to the $1,900,000 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 $599,000 aggregate principal amount of the Notes (the “RP Pro-Rated Tendered Notes”);

(2) we accepted all $599,000 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 $1,301,000 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 March 25, 2019.

Accordingly, pursuant to the terms of the Indenture, we were permitted to make one or more restricted payments 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 $299,401,000 (the "RP Basket") without having to make another offer to repurchase Notes. We intend to use the RP Basket to pay the April 2019 Special Dividend and make repurchases under the New Stock Repurchase Program.

Tender Offer

As of the Expiration Date, $415,099,000 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 31.5789% was applied to the $415,099,000 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 $130,966,000 aggregate principal amount of the Notes (the “TO Pro-Rated Tendered Notes”);

(2) we accepted all $130,966,000 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 $284,133,000 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 March 26, 2019. In connection with the payment, we recognized a loss on early extinguishment of debt of 9.8 million.

Restricted Cash

As of March 31, 2019, restricted cash included $0.8 million in other long-term assets in the Condensed Balance Sheet which represents amounts invested in certificate of deposits as financial assurance for post mining reclamation obligations.

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. 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 or to develop the high-quality met coal recoverable reserves at our Blue Creek in the future could also affect our capital needs or cause future capital expenditures to be higher than in the past and/or higher than our estimates.

28

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 that are beyond our control.

Our capital expenditures were $24.4 million and $22.5 million for the three months ended March 31, 2019 and March 31, 2018, respectively. Capital expenditures for these periods primarily related to investments required to maintain our property, plant and equipment. We evaluate our spending on an ongoing basis in connection with our mining plans and the prices of met coal taking into consideration the funding available to maintain our operations at optimal production levels.

We expect to continue making significant capital expenditures in 2019 above our normal sustaining capital expenditures that we believe will further improve efficiency, reliability and production levels in 2019 and the future. Total capital spending will depend upon a number of factors, including business and economic conditions, the met coal pricing environment and our expected financial performance and our capital expenditures can be reduced if those conditions were to deteriorate in 2019 or beyond. Our capital spending is expected to range from $100.0 to $120.0 million for the full year 2019, consisting of sustaining capital expenditures of approximately $70.0 to $87.0 million and discretionary capital expenditures of approximately $30.0 to $33.0 million. Our sustaining capital expenditures include expenditures related to longwall operations, new ventilation, and bleeder shafts. Our discretionary capital expenditures include an additional set of new longwall shields and other various operational improvements, which will increase efficiency, increase production and lower costs over time. In addition, we expect to incur mine development costs relating to Mine No. 4 of approximately $18.0 to $22.0 million for the full year 2019. Because of the long lead times on the discretionary capital spending, we expect to realize the benefits of those projects primarily in 2020 and beyond. These amounts set forth above do not include any potential spending associated with Blue Creek should we decide to develop it for production in the future.

Blue Creek

We continue to advance the Blue Creek growth project and evaluate various development options to enhance project economics and reduce execution risk. We believe that Blue Creek represents one of the few remaining untapped reserves of premium high volatility ("High Vol") A met coal in the United States and that it has the potential to provide us with meaningful growth.

We are currently studying the feasibility of a single longwall operation that could produce up to 2.7 million metric tons annually. While we continue to optimize project parameters, preliminary engineering studies have estimated that initial capital expenditures of approximately $550 million to $600 million would be required to be spent over five years in order to develop this project. Once developed, we believe that Blue Creek has the potential to offer robust project returns across a range of met coal prices.

According to our third party reserve report, Blue Creek contains approximately 103.0 million metric tons of recoverable reserves and we have the ability to acquire adjacent reserves that would increase total reserves to over 154 million metric tons. Based on our preliminary engineering studies, Blue Creek is expected to have a mine life in excess of 40 years based on a single longwall operation. Also, based on our preliminary engineering studies, we believe that the geology and reserve base of Blue Creek could support a second longwall that would be expected to increase annual production up to 5.4 million metric tons, which would provide us with future growth opportunities at Blue Creek.

Our third party reserve report indicates that Blue Creek would produce a premium High Vol A met coal that is characterized by low-sulfur and high CSR. High Vol A has traditionally priced at a slight discount to the Australian Premium LV and the U.S. LV coals; however, recently has been priced at or slightly above 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 believe this creates an opportunity for Blue Creek to take advantage of favorable pricing dynamics driven by the declining supply of premium High Vol A coals.

We previously announced plans to pursue a number of activities in 2019 to maintain project momentum and optimize Blue Creek's project parameters. These activities are expected to include additional core drilling, finalizing the rail loop design, and permitting the slurry storage and coarse refuse areas. Additionally, we plan to continue to explore potential off-take arrangements as well as project financing alternatives. We expect Blue Creek will be fully permitted and 'shovel ready' by early 2020 at which point we would be in a position to make a decision on development.

29

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 March 31, 2019, we had outstanding surety bonds and letters of credit with parties for post-mining reclamation at all of our U.S. mining operations totaling $44.4 million, and $2.1 million, respectively, for miscellaneous purposes.

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 coal. We sell most of our met coal under fixed supply contracts primarily with indexed pricing terms and volume terms of up to one to three years. Sales commitments in the met 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. All of our derivative instruments were entered into for hedging purposes rather than speculative trading.

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 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 March 31, 2019 and December 31, 2018, we did not have any allowance for credit losses associated with our trade accounts receivables.

Interest Rate Risk

Our Notes have a fixed rate of interest of 8.00% per annum and are payable semi-annually in arrears on May 1 and November 1 of each year.

Our ABL Facility bears an interest rate equal to LIBOR plus an applicable margin, which is based on the average availability of the commitments under the ABL Facility, ranging currently from 150 bps to 200 bps. 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 March 31, 2019, assuming we had $125.0 million outstanding under our ABL Facility, a 100 bps point increase or decrease in interest rates would increase or decrease our annual interest expense under the ABL Facility by approximately $1.3 million. Furthermore, such interest rates under our ABL Facility are based upon benchmarks that are subject to potential change or elimination, including as a result of the announcement from the United Kingdom Financial Conduct Authority ("FCA"), which regulates LIBOR, that it intends to stop compelling banks to submit rates for the calculation of LIBOR after 2021.

Impact of Inflation

While inflation may impact our revenues and cost of sales, we believe the effects of inflation, if any, on our results of operations and financial condition have not been significant. However, there can be no assurance that our results of operations and financial condition will not be materially impacted by inflation in the future.

31

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 March 31, 2019. Based on the evaluation of our disclosure controls and procedures as of March 31, 2019, our Chief Executive Officer and Chief Financial Officer have concluded that, as of March 31, 2019, 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 10 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.

There have been no material changes to the risk factors disclosed in "Risk Factors" in "Part 1, Item 1A. Risk Factors" in our 2018 Annual 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 report, you should carefully consider the risks discussed in "Part I, "Item 1A. Risk Factors" in our 2018 Annual Report, which could materially affect our business, financial condition or future results. However, the risks described in our 2018 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 also materially adversely affect our business, financial condition and/or operating results.

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

The following table sets forth share repurchases of our common stock made during the quarter ended March 31, 2019:

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 March 31, 2019, 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 March 31, 2019. The second table presents legal actions pending before the Federal Mine Safety and Health Review Commission ("FMSHRC") for each of our mines as of March 31, 2019, together with the number of legal actions initiated and the number of legal actions resolved during the quarter ended March 31, 2019.

(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, 2018. 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:

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 producer and exporter of met coal for a diversified customer base of blast furnace steel producers located primarily in Europe, South America and Asia. 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 generally accepted accounting principles 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 consolidated financial statements and related notes included in the Company's Annual Report on Form 10-K for the year ended December 31, 2018. Operating results for the three months ended March 31, 2019 and March 31, 2018 are not necessarily indicative of the final results that may be expected for the year ended December 31, 2019. The balance sheet at December 31, 2018 has been derived from the audited financial statements for the year ended December 31, 2018 included in the Company's Annual Report on Form 10-K for the year ended December 31, 2018 (the "2018 Annual Report").

Accounting Policies [Abstract]

Summary of Significant Accounting Policies

Summary of Significant Accounting Policies

Our significant accounting policies are consistent with those disclosed in Note 2 to our audited financial statements included in the 2018 Annual Report, except for changes related to new accounting pronouncements described in "New Accounting Pronouncements".

Cash and Cash Equivalents and Restricted Cash

The following table provides a reconciliation of cash and cash equivalents and restricted cash reported within the Condensed Balance Sheets that sum to the total of the same such amounts shown in the Condensed Statements of Cash Flows (in thousands):

	March 31, 2019		December 31, 2018
Cash and cash equivalents	$	154,912	$	205,577
Restricted cash included in other long-term assets	830		828
Total cash and cash equivalents and restricted cash included in the Condensed Statements of Cash Flows	$	155,742	$	206,405

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. As of March 31, 2019 and December 31, 2018, restricted cash included in other long-term assets in the Condensed Balance Sheets represents amounts invested in certificates of deposits as financial assurance for post mining reclamation obligations.

Short-Term Investments

Instruments with maturities greater than three months, but less than twelve months, are included in short-term investments. The Company purchases United States Treasury ("Treasury") bills with maturities ranging from six to twelve months which are classified as held to maturity and are carried at amortized cost, which approximates fair value. Securities classified as held to maturity are those securities that management has the intent and ability to hold to maturity.

As of March 31, 2019 and December 31, 2018, the Company’s short-term investments consisted of $17.5 million in Treasury bills with a maturity of six months. These Treasury bills were posted as collateral for the self-insured black lung related claims asserted by or on behalf of former employees of Walter Energy, Inc. 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 our customers are satisfied; for all contracts this occurs when control of the promised goods have been transferred to our 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 included in all other revenues, as disclosed in Note 14.

Since February 2017, we have had an arrangement with XCoal Energy & Resource ("XCoal") to serve as XCoal's strategic partner for exports of low-volatility HCC. Under this arrangement, XCoal takes title to and markets coal that we would historically have sold on the spot market, in an amount of the greater of (i) 10% of our total production during the applicable term of the arrangement or (ii) 250,000 metric tons. During the three months ended March 31,2019 and 2018, XCoal accounted for approximately $94.9 million, or 25.8% of total revenues, and $86.2 million, or 20.8% of total revenues, respectively.

New Accounting Pronouncements

The Company adopted Accounting Standards Update (“ASU”) No. 2016-02, "Leases (Topic 842)" as of January 1, 2019 using the modified retrospective approach (the "New Leases Standard"). The New Leases Standard requires a lessee to recognize a right-of-use asset and lease liability on its balance sheet for all leases. The Company has chosen to use its adoption date as its date of initial application. As a result, financial information will not be updated and the disclosures required under the new standard will not be provided for dates and periods before January 1, 2019.

The Company made an accounting policy election that leases with an initial term of 12 months or less will remain off of its balance sheet and lease payments will instead be recognized in the Condensed Statements of Operations on a straight-line basis over the lease term. Additionally, the Company elected the package of practical expedients for all leases, which permits the Company to forego reassessing expired or existing contracts to determine: whether they are or contain leases, lease classification, and initial direct costs. Management elected the optional transition expedient which allows the Company to continue applying the current policy for accounting for expired or existing land easement contracts that were not previously accounted for under GAAP. New or modified land easements executed after adoption will be considered under the New Lease Standard. The Company elected the practical expedient as an accounting policy election for all asset classifications, which allows it to account for them as a single lease component, rather than as separate lease and non-lease components.

As the Company’s historical operating leases are primarily short term rental agreements of less than one year, the Company did not record any additional lease assets or lease liabilities upon adoption of the New Leases Standard. The New Leases Standard did not impact the Company's balance sheet or consolidated net income and had no impact on cash flows. As of March 31, 2019, the Company has a right-of-use asset of $5.8 million, net of accumulated amortization, and a liability of $6.9 million.

On August 17, 2018, the SEC adopted a final rule that eliminates or amends certain disclosure requirements that were deemed redundant and outdated in light of changes in SEC requirements, U.S. GAAP or changes in technology or the business environment. The rule also requires registrants to include in their interim financial statements a reconciliation of changes in stockholders’ equity in the notes or as a separate statement. The analysis should reconcile the beginning balance to the ending balance of each caption in shareholders’ equity for each period for which an income statement is required to be filed. The final rule became effective November 5, 2018. Beginning in the first quarter of fiscal 2019, we have provided a reconciliation for the quarterly period as well as the comparable prior period in this Form 10-Q. The eliminated or amended disclosures did not have a material impact on the Company’s unaudited condensed financial statements.

Income Taxes

Income Taxes

For the three months ended March 31, 2019, 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 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.

The Company had income tax expense of $28.0 million for the three months ended March 31, 2019. The Company had no income tax expense for the three months ended March 31, 2018 due to the utilization of NOLs to offset taxable income for which a full valuation allowance was recorded. As a result of various favorable factors further discussed in the 2018 Annual Report, the Company released its valuation allowance against its net deferred income tax assets in the fourth quarter of 2018.

Senior Secured Notes

On November 2, 2017, the Company issued $350.0 million aggregate principal amount of its 8.00% Senior Secured Notes due 2024 (the "Original Notes"). It then issued an additional $125.0 million in aggregate principal amount of its 8.00% Senior Secured Notes due 2024 (the “New Notes” and, together with the Original Notes, the "Notes") on March 1, 2018. The New Notes were issued as "Additional Notes" under the indenture dated as of November 2, 2017 (the "Original Indenture"), among the Company, the subsidiary guarantors party thereto and Wilmington Trust, National Association, as trustee and priority lien collateral trustee, as supplemented by the First Supplemental Indenture, dated as of March 1, 2018 (the "First Supplemental Indenture" and, the Original Indenture as supplemented thereby and by the Second Supplemental Indenture, dated as of March 2, 2018, the "Indenture"). The Notes mature on November 1, 2024 and interest is payable on May 1 and November 1 of each year.

Offers to Purchase the Notes

On February 21, 2019, 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 March 22, 2019 (the “Expiration Date”).

Restricted Payment Offer

As of the Expiration Date, $1,900,000 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 31.5789% was applied to the $1,900,000 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 $599,000 aggregate principal amount of the Notes (the “RP Pro-Rated Tendered Notes”);

(2) the Company accepted all $599,000 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 $1,301,000 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 March 25, 2019.

Accordingly, pursuant to the terms of the Indenture, the Company was permitted to make one or more restricted payments 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 $299,401,000 (the "RP Basket") without having to make another offer to repurchase Notes. The Company intends to use the RP Basket to pay the April 2019 Special Dividend (as defined below) and make repurchases under the New Stock Repurchase Program (as defined below).

Tender Offer

As of the Expiration Date, $415,099,000 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 31.5789% was applied to the $415,099,000 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 $130,966,000 aggregate principal amount of the Notes (the “TO Pro-Rated Tendered Notes”);

(2) the Company accepted all $130,966,000 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 $284,133,000 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 March 26, 2019.

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 $9.8 million during the three months ended March 31, 2019.

Leases [Abstract]

Leases

Leases

The Company primarily enters into rental agreements for certain mining equipment that are for periods of 12 months or less, some of which include options to extend the leases. Leases that are for periods of 12 months or less are not recorded on the balance sheet in accordance with the Company's accounting policy election described in Note 2. The Company recognizes lease expense on these agreements on a straight-line basis over the lease term.

Leases

Leases

The Company primarily enters into rental agreements for certain mining equipment that are for periods of 12 months or less, some of which include options to extend the leases. Leases that are for periods of 12 months or less are not recorded on the balance sheet in accordance with the Company's accounting policy election described in Note 2. The Company recognizes lease expense on these agreements on a straight-line basis over the lease term. Additionally, the Company has finance leases for certain mining equipment that expires over various contractual periods. The leases have remaining lease terms of one to two years.

2017 Equity Plan

On February 8, 2019, the Company awarded 306,314 restricted stock unit awards under the Company's 2017 Equity Incentive Plan (the "2017 Equity Plan"). These awards have certain service-based, performance-based and market-based vesting conditions, as applicable. The service-based awards vest over a period of three years and the performance-based and market-based awards are based on the Company's performance in each of the three years. The Company recognized approximately $0.5 million in stock compensation expense associated with these awards for the three months ended March 31, 2019.

Additionally, the Company awarded $1.5 million of restricted stock unit awards under the 2017 Equity Plan that can be settled in shares or in cash at the election of employees. These awards have certain service-based and performance-based vesting conditions and can be earned no later than December 31, 2021. If the Company were to settle these awards in shares these awards would represent 49,342 shares based on the Company's closing share price on March 31, 2019. The Company recognized approximately $86 thousand in stock compensation expense associated with these awards for the three months ended March 31, 2019.

As of March 31, 2019, there were 157,124 restricted stock unit awards for which the service-based vesting conditions for these awards were not met as of the measurement date. As such, these awards were excluded from basic earnings per share. These awards had a 28,302 share impact on dilutive weighted average shares. As of March 31, 2019, there were 280,492 restricted stock unit awards for which the performance-based and market-based vesting conditions were not met as of the measurement date and, as such, these awards were excluded from basic and diluted earnings per share. For the 49,342 restricted stock unit awards classified as a liability, the Company considered the impact on diluted earnings as if the award was settled in cash or in shares. As the impact of these shares is anti-dilutive, they have been excluded from both basic and diluted earnings per share.

As of March 31, 2019, there were 43,580 shares of our common stock contingently issuable upon the settlement of a vested phantom unit award granted under our 2016 Equity Plan (as defined below) and 13,157 shares of our common stock contingently issuable upon the settlement of a vested restricted stock unit award under our 2017 Equity Plan, as applicable. The settlement date for these awards is the earlier of a change in control as described in our 2016 Equity Plan or 2017 Equity Plan, as applicable, or five years from the grant date. These awards are vested and, as such, have been included in the weighted average shares used to compute basic and diluted net income per share.

2016 Equity Plan

As of March 31, 2019, there were 124,307 restricted stock unit awards granted under the Company's 2016 Equity Incentive Plan (the "2016 Equity Plan") to certain directors and employees, for which the service-based vesting conditions for these awards were not met as of the measurement date. As such, these awards were excluded from basic earnings per share. These awards had an 90,419 share impact on dilutive weighted average shares.

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 that it is in substantial 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 March 31, 2019 and December 31, 2018, 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 a number of lawsuits arising in the ordinary course of their businesses. 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 March 31, 2019 and December 31, 2018, there were no items accrued for miscellaneous litigation.

Commitments and Contingencies—Other

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 March 31, 2019 and December 31, 2018, 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 land owners. These leases convey mining rights to the Company in exchange for royalties to be paid to the land owner 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 expense was $26.7 million for the three months ended March 31, 2019 and $22.3 million for the three months ended March 31, 2018.

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 as determined from time to time by the Company and other considerations. 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.

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 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 expense, and income tax expense by segment.

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

	For the three months ended March 31,

Capital Expenditures
Mining	23,210	$	21,096
All other	1,185	1,446
Total capital expenditures	24,395	$	22,542

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, net interest expense, income tax expense, loss on early 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):

Summary of Significant Accounting Policies (Policies)

3 Months Ended

Mar. 31, 2019

Accounting Policies [Abstract]

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 generally accepted accounting principles 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 and Restricted Cash

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. As of March 31, 2019 and December 31, 2018, restricted cash included in other long-term assets in the Condensed Balance Sheets represents amounts invested in certificates of deposits as financial assurance for post mining reclamation obligations.

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 purchases United States Treasury ("Treasury") bills with maturities ranging from six to twelve months which are classified as held to maturity and are carried at amortized cost, which approximates 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 our customers are satisfied; for all contracts this occurs when control of the promised goods have been transferred to our 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 included in all other revenues, as disclosed in Note 14.

New Accounting Pronouncements

New Accounting Pronouncements

The Company adopted Accounting Standards Update (“ASU”) No. 2016-02, "Leases (Topic 842)" as of January 1, 2019 using the modified retrospective approach (the "New Leases Standard"). The New Leases Standard requires a lessee to recognize a right-of-use asset and lease liability on its balance sheet for all leases. The Company has chosen to use its adoption date as its date of initial application. As a result, financial information will not be updated and the disclosures required under the new standard will not be provided for dates and periods before January 1, 2019.

The Company made an accounting policy election that leases with an initial term of 12 months or less will remain off of its balance sheet and lease payments will instead be recognized in the Condensed Statements of Operations on a straight-line basis over the lease term. Additionally, the Company elected the package of practical expedients for all leases, which permits the Company to forego reassessing expired or existing contracts to determine: whether they are or contain leases, lease classification, and initial direct costs. Management elected the optional transition expedient which allows the Company to continue applying the current policy for accounting for expired or existing land easement contracts that were not previously accounted for under GAAP. New or modified land easements executed after adoption will be considered under the New Lease Standard. The Company elected the practical expedient as an accounting policy election for all asset classifications, which allows it to account for them as a single lease component, rather than as separate lease and non-lease components.

As the Company’s historical operating leases are primarily short term rental agreements of less than one year, the Company did not record any additional lease assets or lease liabilities upon adoption of the New Leases Standard. The New Leases Standard did not impact the Company's balance sheet or consolidated net income and had no impact on cash flows. As of March 31, 2019, the Company has a right-of-use asset of $5.8 million, net of accumulated amortization, and a liability of $6.9 million.

On August 17, 2018, the SEC adopted a final rule that eliminates or amends certain disclosure requirements that were deemed redundant and outdated in light of changes in SEC requirements, U.S. GAAP or changes in technology or the business environment. The rule also requires registrants to include in their interim financial statements a reconciliation of changes in stockholders’ equity in the notes or as a separate statement. The analysis should reconcile the beginning balance to the ending balance of each caption in shareholders’ equity for each period for which an income statement is required to be filed. The final rule became effective November 5, 2018. Beginning in the first quarter of fiscal 2019, we have provided a reconciliation for the quarterly period as well as the comparable prior period in this Form 10-Q. The eliminated or amended disclosures did not have a material impact on the Company’s unaudited condensed financial statements.
