Investor Presentation March 2022

2 Forward Looking Statements This document includes forward-looking statements. These forward-looking statements are based on Alpha's expectations and beliefs concerning future events and involve risks and uncertainties that may cause actual results to differ materially from current expectations. These factors are difficult to predict accurately and may be beyond Alpha's control. The following factors are among those that may cause actual results to differ materially from our forward-looking statements: • 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; • our indebtedness and potential future indebtedness; • depressed levels or declines in coal prices; • the effects of the COVID-19 pandemic on our operations and the world economy; • 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; • worldwide market demand for coal, steel, and electricity, including demand for U.S. coal exports, and competition in coal markets; • 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 and the environmental impacts of coal combustion; • our ability to obtain or renew surety bonds on acceptable terms or maintain our current bonding status; • our ability to meet collateral requirements; • the imposition or continuation of barriers to trade, such as tariffs; • reductions or increases in customer coal inventories and the timing of those changes; • our production capabilities and costs; • 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; • inflationary pressures on supplies and labor and significant or rapid increases in commodity prices; • railroad, barge, truck and other transportation availability, performance and costs; • inherent risks of coal mining, including those that are beyond our control; • changes in the ownership of our equity, which may significantly further reduce the annual amount of the net operating loss and other carryforwards available to be utilized; • changes in, interpretations of, or implementations of domestic or international tax or other laws and regulations, including the Tax Cuts and Jobs Act and its related regulations; • our ability to self-insure certain of our black lung obligations without a significant increase in required collateral; • our relationships with, and other conditions affecting, our customers, including the inability to collect payments from our customers if their creditworthiness declines; • 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; • our ability to obtain, maintain or renew any necessary permits or rights, and our ability to mine properties due to defects in title on leasehold interests; • attracting and retaining key personnel and other employee workforce factors, such as labor relations; • funding for and changes in employee benefit obligations; • cybersecurity attacks or failures, threats to physical security, extreme weather conditions or other natural disasters; • reclamation and mine closure obligations; • utilities switching to alternative energy sources such as natural gas, renewables and coal from basins where we do not operate; • our assumptions concerning economically recoverable coal reserve estimates; • failures in performance, or non-performance, of services by third-party contractors, including contract mining and reclamation contractors; and • disruption in third-party coal supplies. Forward-looking statements in this document or elsewhere speak only as of the date made. New uncertainties and risks arise from time to time, and it is impossible for Alpha to predict these events or how they may affect Alpha. Except as required by law, Alpha has no duty to, and does not intend to, update or revise the forward-looking statements in this document or elsewhere. In light of these risks and uncertainties, investors should keep in mind that results, events or developments discussed in any forward-looking statement made in this document may not occur.

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 historically varied 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) Rate assumes no further ownership change limitations on the usage of net operating losses.

The Section 382 annual base limitations are $1.0 million for the 2015 NOL and $17.5 million for the 2017 NOL. The estimated 2017 NOL availability does not include potential increases to the Section 382 annual base limitation from the recognition of built-in gains. (2) The 2019 and 2020 NOLs do not expire, but their utilization is limited to 80% of taxable income. (3) 2022 utilization availability for each NOL tranche assumes no further ownership changes occur. (4) As of December 31, 2021, the Company has recorded a valuation allowance against its deferred tax assets (including Federal NOLs).
