2 FORWARD-LOOKING STATEMENTS This presentation includes statements of our expectations, intentions, plans and beliefs that constitute "forward-looking statements." 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," "believe," "could," "estimate," "expect," "intend," "may," "might," "plan," "predict," "project," "should" and similar terms and phrases, including references to assumptions, in this presentation to identify forward-looking statements, but these terms and phrases are not the exclusive means of identifying such 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 expressed in or implied by these forward-looking statements. The following factors are among those that may cause actual results to differ materially from our forward-looking statements: • depressed levels or declines in coal prices; • the financial performance of the company; • our liquidity, results of operations and financial condition; • our ability to generate sufficient cash or obtain financing to fund our business operations; • worldwide market demand for coal and steel, including demand for U.S. coal exports, and competition in coal markets; • railroad, barge, truck, port and other transportation availability, performance and costs; • steel and coke producers switching to alternative energy sources such as natural gas, renewables and coal from basins where we do not operate; • our ability to meet collateral requirements for, and fund, employee benefit obligations; • our ability to self-insure certain of our black lung obligations; • our ability to obtain or renew surety bonds on acceptable terms or maintain our current bonding status; • the imposition, continuation or modification of barriers to trade, such as tariffs, and the unpredictability of these events; • attracting and retaining key personnel and other employee workforce factors, such as labor relations; • our ability to consummate financing or refinancing transactions, and other services, and the form and degree of these services available to us, which may be significantly limited by the lending, investment and similar policies of financial institutions and insurance companies regarding carbon energy producers, the environmental impacts of coal combustion or other factors; • inflationary pressures on supplies and labor and significant or rapid increases in commodity prices; • our costs of complying with health and safety regulations, including but not limited to MSHA's silica regulations; • changes in domestic or international environmental laws and regulations, and court decisions, including those directly affecting our coal mining and production and those affecting our customers' coal usage, including potential climate change initiatives; • failures in performance, or non-performance, of services by third-party contractors, including contract mining and reclamation contractors or other counterparties; • disruptions in delivery or changes in pricing from third-party vendors of key equipment and materials that are necessary for our operations, such as diesel fuel, steel products, explosives, tires and purchased coal; • our production capabilities and costs; • our indebtedness as we may incur it from time to time; • our ability to execute our share repurchase program; • cybersecurity attacks or failures, threats to physical security, extreme weather conditions or other natural disasters; • increased volatility and uncertainty regarding worldwide markets, seaborne transportation and our customers as a result of developments in and around Ukraine, Iran, and the broader Middle East; • changes in, renewal or acquisition of, terms of and performance of customers under coal supply arrangements and the refusal by our customers to receive coal under agreed-upon contract terms; • reductions or increases in customer coal inventories and the timing of those changes; • our ability to obtain, maintain or renew any necessary permits or rights; • inherent risks of coal mining, including those that are beyond our control; • changes in, interpretations of, or implementations of domestic or international tax or other laws and regulations, including U.S. federal legislation and its related regulations; • our relationships with, and other conditions affecting, our customers, including the inability to collect payments from our customers if their creditworthiness declines; • reclamation and mine closure obligations; • our assumptions concerning economically recoverable coal reserve estimates; and • other factors, including the other factors discussed in the "Management's Discussion and Analysis of Financial Condition and Results of Operations" section included elsewhere in our Quarterly Report on Form 10-Q and the "Management's Discussion and Analysis of Financial Condition and Results of Operations" and "Risk Factors" sections included in our Annual Report on Form 10-K for the year ended December 31, 2025. The list of factors identified above is not exhaustive. We caution readers not to place undue reliance on any forward looking statements, which are based on information currently available to us and speak only as of the dates on which they are made. When considering these forward-looking statements, you should keep in mind the cautionary statements in this presentation. We do not undertake any responsibility to publicly revise these forward-looking statements to take into account events or circumstances that occur after the date of this presentation. Additionally, except as expressly required by federal securities laws, we do not undertake any responsibility to update you on the occurrence of any unanticipated events, which may cause actual results to differ from those expressed or implied by the forward-looking statements contained in this presentation. See Appendix B for reconciliations of the differences between the financial measures in accordance with U.S. generally accepted accounting principles ("GAAP") and non-GAAP financial measures used in this presentation.

2 1 1 Based on committed and priced coal shipments as of April 29, 2026. Committed percentage based on the midpoint of shipment guidance range. 2 Actual average per-ton realizations on committed and priced tons recognized in future periods may vary based on actual freight expense in future periods relative to assumed freight expense embedded in projected average per-ton realizations. 3 Includes estimates of future coal shipments based upon contract terms and anticipated delivery schedules. Actual coal shipments may vary from these estimates. 4 Note: The Company is unable to present a quantitative reconciliation of its forward-looking non-GAAP cost of coal sales per ton sold financial measures to the most directly comparable GAAP measures without unreasonable efforts due to the inherent difficulty in forecasting and quantifying with reasonable accuracy significant items required for the reconciliation. The most directly comparable GAAP measure, GAAP cost of sales, is not accessible without unreasonable efforts on a forward-looking basis. The reconciling items include freight and handling costs, which are a component of GAAP cost of sales. Management is unable to predict without unreasonable efforts freight and handling costs due to uncertainty as to the end market and FOB point for uncommitted sales volumes and the final shipping point for export shipments. These amounts have varied historically and may continue to vary significantly from quarter to quarter and material changes to these items could have a significant effect on our future GAAP results. 5 Excludes expenses related to non-cash stock compensation and non-recurring expenses. 6 Includes contributions to fund normal operations at our DTA export facility and expected capital investments related to the facility upgrades.

2 3 NON-GAAP FINANCIAL MEASURES The Investor Presentation contains "non-GAAP financial measures." These are financial measures that either exclude or include amounts that are not excluded or included in the most directly comparable measures calculated and presented in accordance with generally accepted accounting principles in the United States ("U.S. GAAP" or "GAAP"). Specifically, we make use of the non-GAAP financial measures "Adjusted EBITDA," "Margin %," "non-GAAP coal revenues," "non-GAAP coal sales realization per ton," "Free Cash Flow," and "Free Cash Flow Conversion." In addition to net income (loss), we use Adjusted EBITDA to measure the operating performance of our reportable segment. Adjusted EBITDA does not purport to be an alternative to net income (loss) as a measure of operating performance or any other measure of operating results, financial performance, or liquidity presented in accordance with GAAP. Moreover, this measure is not calculated identically by all companies and therefore may not be comparable to similarly titled measures used by other companies. Adjusted EBITDA is presented because management believes it is a useful indicator of the financial performance of our coal operations. Margin % is calculated as Adjusted EBITDA divided by total revenues. We use non-GAAP coal revenues to present coal revenues generated, excluding freight and handling fulfillment revenues. Non-GAAP coal sales realization per ton is calculated as non-GAAP coal revenues divided by tons sold. Free Cash Flow is calculated as cash flow from operations less capital expenditures and capital contributions to equity affiliates. Free Cash Flow Conversion is calculated as Free Cash Flow divided by Adjusted EBITDA. The presentation of these measures should not be considered in isolation, or as a substitute for analysis of our results as reported under GAAP. Management uses non-GAAP financial measures to supplement GAAP results to provide a more complete understanding of the factors and trends affecting the business than GAAP results alone. The definition of these non-GAAP measures may be changed periodically by management to adjust for significant items important to an understanding of operating trends and to adjust for items that may not reflect the trend of future results by excluding transactions that are not indicative of our core operating performance. Furthermore, analogous measures are used by industry analysts to evaluate the Company's operating performance. Because not all companies use identical calculations, the presentations of these measures may not be comparable to other similarly titled measures of other companies and can differ significantly from company to company depending on long-term strategic decisions regarding capital structure, the tax jurisdictions in which companies operate, capital investments and other factors. Included on the following slides are reconciliations of non-GAAP financial measures to GAAP financial measures.
