Alpha Metallurgical Resources, Inc. Statement of Coal Resources and Reserves for the Mid-West Virginia Surface Business Unit in Accordance with United States SEC Standards as of December 31, 2021 Central Appalachian Coal Basin West Virginia, USA MARSHALL MILLER & ASSOCIATES, INC. 1 1 Executive Summary 1.1 Property Description Alpha Metallurgical Resources, Inc. (Alpha) authorized Marshall Miller & Associates, Inc. (MM&A) to prepare this Technical Report Summary (TRS) of its controlled coal reserves located at the Mid-West Virginia Surface Business Unit (MWVS or the Property) in Raleigh and Fayette counties, West Virginia. Coal resources and coal reserves are herein reported in imperial units of measurement. The MWVS Operations is comprised of the Kingston surface and underground operations and the Workman Creek surface mines that are part of Mid-West Virginia Underground Operations. Active surface facilities for the met operations include the Workman Creek surface facilities in Raleigh County West Virginia, located along Workman Creek, a tributary to Clear Fork along State Route 1. Workman Creek surface facility are 24 miles northwest of the Beckley, West Virginia, the county seat of Raleigh County; the Kingston surface facilities and preparation plant are near the community of Mossy, along Paint Creek in Fayette County. Kingston is located approximately 25 mile north of Beckley, West Virginia; The Pax loadout is located in the community of Pax, located along Interstate Highway 64/77 and has access to the CSX railroad line. The Pax Loadout is 20 miles north of Beckley, West Virginia (see Figure 1-1). The Property is composed of approximately 119,000 total acres of mineral control, of which nearly all are contained within 10 separate leases and 8 owned properties. The mentioned leases are all subject to Alpha renewing the rights to extend the term of all leases which have various expiration dates, some of which expire in the next several years but are anticipated to be renewed by Alpha.

Coal seams below the Coalburg seam are all historically utilized as coking coal. Strata on the Property, among the active sites, are mostly of the Pennsylvanian-aged (approximately 290 to 330 million years ago) Kanawha Formation. The lower most Sewell coal seam is part of the New River Formation of the Pottsville Series. The rock formations between the coal seams are characterized by proportions of sandstone and shale units. In general, the coal seams reach the highest structural elevations along the southeastern margin of the Property, generally dipping toward the northwest. The area is generally stable with no major faulting and gentle dips. 1.5 Exploration Status The Property has been extensively explored, largely by drilling using continuous coring and rotary drilling methods but also by obtaining coal measurements at mine exposures, and by downhole geophysical methods. Most of the data was acquired or generated by previous owners of the Property. These sources comprise the primary data used in the evaluation of the coal resources and coal reserves on the Property. MM&A examined the data available for the evaluation and incorporated all pertinent information into this TRS. Where data appeared to be anomalous or not representative, that data was excluded from the digital databases and subsequent processing by MM&A. Ongoing exploration has been carried out by Alpha since acquiring the MWVS Business Unit. The Alpha acquired exploration data has been consistent with past drilling activities. 1.6 Operations and Development As of December 31, 2021, MWVS Business Unit is comprised of two surface operations, Kingston and Workman Creek. Active surface mine operations at Workman Creek, include the Long Ridge, Center Contour, Collins Fork and Middle Ridge permits. Active Surface mines and Kingston included the Kingston permit. The surface mines production is approximately 75% metallurgical coal product consisting of Mid-Vol, High-Vol A and Alt Met Coal product and 25% steam coal as a by-product from stripping. These surface mines are traditional contour strip mines that include supplemental highwall mining activity in major seams. MWVS underground mine operations were active at the Kingston 2 Mine, part of the Kingston unit. Kingston 2 produces Mid-Vol product from the Douglas coal seam. Based on the mine plans developed as part of this TRS, annual deep mine production peaks at 1.7 million tons in 2032. Underground reserves will be depleted in 2035. Annual surface production peaks at 3.4 million tons in 2023 and highwall mine production peaks at 0.6 million tons in 2024. Surface and highwall reserves are both depleted in 2042. Alpha Metallurgical Resources, Inc. Statement of Coal Resources and Reserves for the Mid-West Virginia Surface Business Unit in Accordance with United States SEC Standards as of December 31, 2021 Central Appalachian Coal Basin West Virginia, USA MARSHALL MILLER & ASSOCIATES, INC. 4 In addition to the mines, the MWVS Business Unit includes the Kingston Preparation Plant and the Pax loadout facilities. The Kingston Preparation Plant has a design feed rate capacity of 700 raw tons per hour. Primary separation equipment includes heavy media vessels, heavy media cyclones, spirals, and flotation cells, supported by the requisite screens, centrifuges, sumps, pumps, and distribution systems. Coarse and fine refuse are disposed in an adjacent combined fill refuse area and impoundment. Coal Production is also conveyed from Workman Creek, through underground mine works to the Marfork preparation for processing and shipment on the CSX railway. Coal production can be trucked to Mammoth Preparation plant for processing and shipping on the Kanawha River. Shortline railroad connections to the CSX and Norfolk Southern railroads as well as on-site barge loading on the Kanawha River are also available. 1.7 Mineral Resource A coal resource estimate, summarized in Table 1-1 was prepared as of December 31, 2021, for property controlled by Alpha.

Alpha Metallurgical Resources, Inc. Statement of Coal Resources and Reserves for the Mid-West Virginia Surface Business Unit in Accordance with United States SEC Standards as of December 31, 2021 Central Appalachian Coal Basin West Virginia, USA MARSHALL MILLER & ASSOCIATES, INC. 5 1.8 Mineral Reserve The Resource estimate outlined in Table 1-1 inclusive of reserves has been used as the basis for this Reserve calculation, which utilizes a reasonable Preliminary Feasibility Study, a Life-of Mine (LOM) Mine Plan and practical recovery factors. Production modeling was completed with an effective start date of January 1, 2021. Factors that would typically preclude conversion of a coal resource to coal reserve, include the following: inferred resource classification; absence of coal quality; poor mine recovery; lack of access to the deposit; geological encumbrances associated with overlying and underlying strata; thin seam trends; complex structures; and insufficient exploration data. The listed factors have all been considered. Reserve consideration excludes those portions of the resource area, which exhibit the afore mentioned geologic and/ or operational encumbrances. Proven and probable coal reserves were derived from the defined in-situ coal resource considering relevant processing, economic (including technical estimates of capital, revenue and cost), marketing, legal, environmental, socioeconomic, and regulatory factors. The proven and probable coal reserves on the Property are summarized below in Table 1-2.

Coal quality is based on a weighted average of laboratory data from core holes. The combination of surface and inherent moisture is modeled at 6.0-percent. Raw quality and some volatile matter analysis not available for Workman Creek . Workman Creek surface reserves were priced at 60% High-Vol. A and 40% thermal product. Douglas seam volatile matter analysis not available. Douglas seam priced as a Mid-Vol. product, consistent with Kingston 2 production. Actual product moisture is dependent upon multiple geological factors, operational factors, and product contract specifications and can exceed 8-percent. As such, the modeled moisture values provide a level of conservatism for reserve reporting. Totals may not add due to rounding. Workman Creek Surface is modeled as 55% direct-ship and 45% washed to mimic what Alpha is doing, however without any raw quality data for the surface seams a quality composite could not be prepared. See Appendix A for detailed breakdown. Alpha Metallurgical Resources, Inc. Statement of Coal Resources and Reserves for the Mid-West Virginia Surface Business Unit in Accordance with United States SEC Standards as of December 31, 2021 Central Appalachian Coal Basin West Virginia, USA MARSHALL MILLER & ASSOCIATES, INC. 6 In summary, Alpha controls a total of 60.7 Mt (moist basis) of marketable coal reserves at MWVS as of December 31, 2021. Of that total, 38 percent are proven, and 62 percent are probable. Due to the lack of raw coal quality information, all Workman Creek surface reserves have been classified as Probable even though it is an active operation with sales into the thermal and metallurgical markets. Of the 60.7 Mt, 0.7 Mt are owned, and 60.1 Mt are leased coal reserves. Of the total, 44.0 Mt are surface mineable, 6.2 Mt are highwall mineable, and 10.5 Mt are underground mineable. Marketable coal reserves are 13.7 Mt are thermal and 47.1 Mt are metallurgical. Of the total, 51.0 Mt are assigned, and the remaining 9.8 Mt are unassigned. 1.9 Capital Summary Alpha provided MM&A with information related to the number of currently operating production units at the MWVS Business Unit. MM&A’s capital schedules assume that major equipment rebuilds occur over the course of each machine’s remaining assumed operating life. Replacement equipment was scheduled based on MM&A’s experience and knowledge of mining equipment and industry standards with respect to the useful life of such equipment. As one mine is depleted, the equipment is moved to its replacement mine. The capital expenditures tables detail costs for major equipment and infrastructure such as conveyor belt terminal groups. “Other” costs include expenditures for mine access and construction, mine extension capital and miscellaneous costs. A summary of the estimated capital for the consolidated MWVS operations is provided in Figure 1-2 below.
Alpha Metallurgical Resources, Inc. Statement of Coal Resources and Reserves for the Mid-West Virginia Surface Business Unit in Accordance with United States SEC Standards as of December 31, 2021 Central Appalachian Coal Basin West Virginia, USA MARSHALL MILLER & ASSOCIATES, INC. 7 Figure 1-2: Projected Capital Expenditures – Consolidated MWVS Business Unit 1.10 Operating Costs Alpha provided historical costs and budgeted projections of operating costs for its active mines including: > Underground operations at Kingston 2 and Kingston 10. > Surface mines at Pax Surface, Workman Creek North, Workman Creek South, Republic, Kingston Surface. > Highwall miner operations at Pax HWM, WC North HWM, WC South HWM, Republic HWM and Kingston HWM. MM&A used the historical and/or budget cost information as a reference and developed a personnel schedule for each mine. Hourly labor rates and salaries were based upon information contained in Alpha’s financial summaries. Fringe benefit costs were developed for vacation and holidays, federal and state unemployment insurance, retirement, workers’ compensation and pneumoconiosis, casualty and life insurance, healthcare and bonuses. A cost factor for mine supplies was developed that relates expenditures to mine advance rates for roof control costs and other mine supply costs based on the historical cost data provided by Alpha. Other factors were developed for maintenance and repair costs, rentals, mine power, outside services, coal preparation plant processing, refuse handling, coal loading, property taxes, and insurance and bonding and other direct mining costs. Alpha Metallurgical Resources, Inc. Statement of Coal Resources and Reserves for the Mid-West Virginia Surface Business Unit in Accordance with United States SEC Standards as of December 31, 2021 Central Appalachian Coal Basin West Virginia, USA MARSHALL MILLER & ASSOCIATES, INC. 8 Appropriate royalty rates were assigned for production from leased coal lands and sales taxes were calculated for state severance taxes, the federal black lung excise tax, and federal and state reclamation fees. Pricing data as provided by Alpha is described in Table 16-2. The pricing data assumes a flat-line long term realization average of $144 per short ton port loading, with an average of $102.26 netback pricing reflective of the mid-volatile product, $144 per short ton port loading with an average of $111.29 per short ton netback pricing reflective of the low-volatile product, and $138 per short ton port loading, with an average of $108.08 netback pricing reflective of the high-volatile product currently sold at MWVS. A portion of the surface mine production is also thermal product which assumes a flat-line long term realization of $76 per short ton with an average of $66.68 per ton netback pricing. The LOM blended average netback pricing for the MWVS reserves is $95.97 per ton. These estimates are based on long term pricing published by third party sources and adjusted for quality and transportation. A large majority of the coal sold by Alpha and their MWVS business group is shipped internationally as part of blended products from other business units within Alpha or sourced from other companies. These netback adjustments reflect these additional costs carried after the products leave the MWVS business unit. A summary of the projected operating costs for the consolidated MWVS operations is provided in Figure 1-3. Figure 1-3: MWVS Business Unit Operating Costs

The results of this financial model are not intended to represent a bankable feasibility study, required for financing of any current or future mining operations contemplated for the Alpha properties, but are intended to establish the economic viability of the estimated coal reserves. Cash flows are simulated on an annual basis based on projected production from the coal reserves. The discounted cash flow analysis presented herein is based on an effective date of January 1, 2022. On an un-levered basis, the NPV of the project cash flow after taxes represents the Enterprise Value of the project. The project cash flow, excluding debt service, is calculated by subtracting direct and indirect operating expenses and capital expenditures from revenue. Direct costs include labor, operating supplies, maintenance and repairs, facilities cost for materials handling, coal preparation, refuse disposal, coal loading, reclamation, and general and administrative costs. Indirect costs include statutory and legally agreed upon fees related to direct extraction of the mineral. The indirect costs are the Federal black lung tax, Federal and State reclamation taxes, property taxes, coal production royalties, and income taxes. The Alpha mines’ historical costs provided a useful reference for MM&A’s cost estimates. Table 1-3 shows LOM tonnage, P&L, and EBITDA for each Alpha mine at MWVS.

In addition, the financial model includes 5.8 Mt clean tons of resources. Consolidated cash flows are driven by annual sales tonnage, which grows from 3.3 million tons in 2022 to a peak of 5.3 million tons in 2032. Between years 2033 and 2035, sales ranges from 3.4 million to
Alpha Metallurgical Resources, Inc. Statement of Coal Resources and Reserves for the Mid-West Virginia Surface Business Unit in Accordance with United States SEC Standards as of December 31, 2021 Central Appalachian Coal Basin West Virginia, USA MARSHALL MILLER & ASSOCIATES, INC. 11 4.5 million tons and between years 2036-2042, sales range from 0.8 million tons to 1.3 million tons. Projected consolidated revenue grows from $77 million in 2022 to a peak of $517 million in 2032. Revenue totals $6.5 billion for the project’s life. Consolidated cash flow from operations is positive throughout the projected operating period, with the exception of post-production years, due to end-of-mine reclamation spending. Consolidated cash flow from operations peaks at $146.9 million in 2032 and totals $1.6 billion over the project life. Capital expenditures total $177.8 million during the first five years and $312.2 million over the project’s life. 1.11.1 Discounted Cash Flow Analysis Cash flow after tax, but before debt service, generated over the life of the project was discounted to NPV at a 14.67% discount rate, which represents MM&A’s estimate of the constant dollar, risk adjusted WACC for likely market participants if the subject reserves were offered for sale. On an un-levered basis, the NPV of the project cash flows represents the Enterprise Value of the project and amounts to $447.2 million. Alpha is an active producer, and the financial model shows positive net cash flow for each year of the operating life of the MWVS reserves. The pre-feasibility financial model prepared for the TRS was developed to test the economic viability of each coal resource area. The NPV estimate was made for purposes of confirming the economics for classification of coal reserves and not for purposes of valuing Alpha or its MWVS assets. Mine plans were not optimized, and actual results of the operations may be different, but in all cases, the mine production plan assumes the properties are under competent management. 1.11.2 Sensitivity Analysis Sensitivity of the NPV results to changes in the key drivers is presented in the chart below. The sensitivity study shows the NPV at the 14.67% discount rate when Base Case sales prices, operating costs, capital costs and discount rate are increased and decreased in increments of 5% within a +/- 15% range. Alpha Metallurgical Resources, Inc. Statement of Coal Resources and Reserves for the Mid-West Virginia Surface Business Unit in Accordance with United States SEC Standards as of December 31, 2021 Central Appalachian Coal Basin West Virginia, USA MARSHALL MILLER & ASSOCIATES, INC. 12 Figure 1-4: Sensitivity of NPV As shown, NPV is quite sensitive to change in sales price and operating cost estimates, and slightly sensitive to changes in capital cost estimates. 1.12 Permitting Alpha has obtained all mining and discharge permits to operate its active mines and processing, loadout, or related support facilities. MM&A is unaware of any obvious or current Alpha permitting issues that are expected to prevent the issuance of future permits. Alpha, along with all coal producers, is subject to a level of uncertainty regarding future clean water permits due to United States Environmental Protection Agency (EPA) involvement with state programs. 1.13 Conclusion and Recommendations Sufficient data has been obtained through various exploration and sampling programs and mining operations to support the geological interpretations of seam structure and thickness for coal horizons situated on the MWVS properties. The data is of sufficient quantity and reliability to reasonably support the coal resource and coal reserve estimates in this TRS. The geological data and preliminary feasibility study, which consider mining plans, revenue, and operating and capital cost estimates are sufficient to support the classification of coal reserves provided herein.
Alpha Metallurgical Resources, Inc. Statement of Coal Resources and Reserves for the Mid-West Virginia Surface Business Unit in Accordance with United States SEC Standards as of December 31, 2021 Central Appalachian Coal Basin West Virginia, USA MARSHALL MILLER & ASSOCIATES, INC. 13 This geologic evaluation conducted in conjunction with the preliminary feasibility study concludes that the 60.7 Mt of marketable underground and surface coal reserves identified on the Property are economically mineable under reasonable expectations of market prices for metallurgical coal products, estimated operation costs, and capital expenditures. 2 Introduction 2.1 Registrant and Terms of Reference This report was prepared for the sole use of Alpha Metallurgical Resources, Inc. (Alpha) and its affiliated and subsidiary companies and advisors. The report provides a statement of coal reserves for Alpha located at the Mid-West Virginia Surface Business Unit (MWVS) in Raleigh and Fayette Counties, West Virginia. Exploration results and Resource calculations were used as the basis for the mine planning and the preliminary feasibility study completed to determine the extent and viability of the reserve. Coal resources and coal reserves are herein reported in imperial units of measurement. 2.2 Information Sources The technical report is based on information provided by Alpha and reviewed by MM&A’s professionals, including geologists, mining engineers, civil engineers, and environmental scientists. MM&A’s professionals hold professional registrations and memberships which qualify them as Qualified Persons in accordance with SEC guidelines. Alpha engaged MM&A to conduct a coal reserve evaluation of the Alpha coal properties as of December 31, 2021. For the evaluation, the following tasks were to be completed: > Conduct site visits of the mines and mine infrastructure facilities. > Process the information supporting the estimation of coal resources and reserves into geological models. > Develop life-of-reserve mine (LOM) plans and financial models. > Hold discussions with Alpha company management; and > Prepare and issue a Technical Report Summary providing a statement of coal reserves which would include: - A description of the mines and facilities. - A description of the evaluation process. Alpha Metallurgical Resources, Inc. Statement of Coal Resources and Reserves for the Mid-West Virginia Surface Business Unit in Accordance with United States SEC Standards as of December 31, 2021 Central Appalachian Coal Basin West Virginia, USA MARSHALL MILLER & ASSOCIATES, INC. 14 - An estimation of coal reserves with compliance elements as stated under the new SEC Guidelines which will become effective for the first fiscal year commencing on or after January 1, 2022. 2.3 Personal Inspections MM&A is very familiar with the MWVS properties, having provided a variety of services in recent years and QP’s involved in this TRS have conducted multiple site visits most recently November 2021. 3 Property Description 3.1 Location The MWV Surface Business Unit is in the Central Appalachian Basin in West Virginia (see Figure 1-1) north of Beckley, West Virginia, and south of Charleston, West Virginia. The Business Unit includes Workman Creek with six surface permits, Kingston with two issued and one pending surface permits and one deep mine located is in Raleigh and Fayette Counties. Surface facilities for the Workman Creek operation are located on Workman Creek, a tributary to Clear Fork along State Route 1 in Raleigh County. Kingston surface facilities are near the community of Mossy , along Paint Creek in Fayette County. The Pax loadout is located in the community of Pax, located along Interstate Highway 64/77 These facilities are all approximately 20 to 27 miles north of Beckley, WV, the county seat of Raleigh County. Numerous small communities are present throughout the Property. The nearest major population centers are Charleston, West Virginia (45 miles north), Bristol, Virginia (160 miles south), Roanoke, Virginia (140 miles east), and Morgantown, West Virginia (170 miles north), and Lexington, KY (220 miles west). The Property is located on the following United States Geological Survey (USGS) Quadrangles: Dorothy, Pax, Arnett, and Eccles. The coordinate system and datum used for the model of the MWV Surface Business Unit, and the subsequent maps were produced in the West Virginia State Plane South system, NAD 27. 3.2 Titles, Claims or Leases The Property is composed of over 119,000 total acres of mineral control, nearly all of which is owned and leased. Alpha’s control is comprised of over 10 separate leases with varying expiration dates and 8 owned properties. Some leases expire over the next several years, but Alpha does not anticipate any challenges related to lease renewal. MM&A has not carried out a separate title verification for the coal properties and has not verified leases, deeds, surveys, or other property control instruments pertinent to the subject resources. Alpha has represented to MM&A that it controls the mining rights to the reserves as shown on its property maps, and MM&A has accepted these as being a true and accurate depiction of the mineral rights controlled by Alpha. The TRS assumes the Property is developed under responsible and experienced management.
Alpha Metallurgical Resources, Inc. Statement of Coal Resources and Reserves for the Mid-West Virginia Surface Business Unit in Accordance with United States SEC Standards as of December 31, 2021 Central Appalachian Coal Basin West Virginia, USA MARSHALL MILLER & ASSOCIATES, INC. 15 3.3 Mineral Rights Alpha supplied property control maps to MM&A related to properties for which mineral and/or surface property are controlled by Alpha. While MM&A accepted these representations as being true and accurate, MM&A has no knowledge of past property boundary disputes or other concerns, through past knowledge of the Property, that would signal concern over future mining operations or development potential. Property control in Appalachia can be intricate. Coal mining properties are typically composed of numerous property tracts which are owned and/or leased from both land holding companies and private individuals or companies. It is common to encounter severed ownership, with different entities or individuals controlling the surface and mineral rights. Mineral control in the region is typically characterized by leases or ownership of larger tracts of land, with surface control generally comprised of smaller tracts, particularly in developed areas. Control of the surface property is necessary to conduct surface mining but is not necessary to conduct underground mining aside from relatively limited areas required for seam access or ventilation infrastructure. Alpha’s executive management team has a history of mining in Central Appalachia and has conveyed to MM&A that it has been successful in acquiring surface rights where needed for past operations. 3.4 Encumbrances No Title Encumbrances are known. By assignment, MM&A did not complete a query related to Title Encumbrances. 3.5 Other Risks There is always risk involved in property control. As is common practice, Alpha, and its predecessors, have had their legal teams examine the deeds and title control to minimize this risk. Historically, property control has not posed any significant challenges related to MWVS’s operations. 4 Accessibility, Climate, Local Resources, Infrastructure and Physiography 4.1 Topography, elevation, and Vegetation Much of topography of the area encompassed by the MWVS Business Unit is typical of the Central Appalachian Plateau’s physiographic province, being rugged deeply dissected by V-shaped river valleys, flanked by steep-sided upland regions. Terrain slopes in the area are mostly steep to very steep with some gently sloping with relatively narrow ridges. Surface elevations near the mine operations range Alpha Metallurgical Resources, Inc. Statement of Coal Resources and Reserves for the Mid-West Virginia Surface Business Unit in Accordance with United States SEC Standards as of December 31, 2021 Central Appalachian Coal Basin West Virginia, USA MARSHALL MILLER & ASSOCIATES, INC. 16 from approximately 1,200 feet above sea level at streams to approximately 3,000 feet at ridge tops. The area is heavily vegetated and has a significant amount of hardwood forests. The Property is not situated near any major urban centers. 4.2 Access and Transport There is general access to the MWV Surface property via a well-developed network of primary, secondary, and unimproved roads from U.S. interstates highways. Interstate 81 to the south and 77 to the east are the primary roads coming into the business unit region. Interstate 81 connects with Bristol, Virginia to the southwest and Roanoke, Virginia to the east. Interstate 77 connects with Charleston, West Virginia to the north and via interstate 64 with Lexington, Kentucky, to the northwest. Numerous secondary and unimproved roads provide direct access to the mine property, some being federal, state, and town maintained. Interstate 64/77 is located near the eastern side of the Property and is the primary throughfare in the area connecting the Property to Beckley, Charleston, and Huntington, West Virginia, to the West and Lexington, Virginia, to the East. Numerous secondary and unimproved roads provide direct access to the mine property, some being federal-, state-, and town- maintained. These include State Route 1 that runs through the Property holdings and provides direct access to Workman Creek surface office. These roads typically stay open throughout the year. Within the Property, unimproved roads are utilized to access surface based deep mine infrastructure. The primary transport means of processed coal is CSX Railroad which services the Marfork preparation plant and the Pax Loadout. Additionally, coal is transported by over-the-road-truck to the Kanawha River for barge transportation at the Marmet dock and also for processing at the Mammoth preparation plant with access to barge and the Kanawha River Railroad shortline that connects to the Norfolk Southern and CSX Transportation railroads. 4.3 Proximity to Population Centers The MWV Surface Business Unit is located near the City of Beckley and is primarily in Raleigh and Fayette Counties, West Virginia, with small portions falling in Kanawha County. There are no large population centers in close proximity to mine operations. The nearest major population centers are Charleston, West Virginia (45 miles north), Bristol, Virginia (160 miles south), Roanoke, Virginia (140 miles east), and Morgantown, West Virginia (170 miles north), and Lexington, KY (220 miles west). As of the 2020 census, Raleigh County had just over 73,300 residents and Fayette County had 40,488 residents. 4.4 Climate and Length of Operating Season The climate of the region is classified as humid continental with four distinct seasons: warm summers, cold winters, and moderate fall and spring seasons. Precipitation in the region is consistent throughout the year, approximately 3 to 5 inches per month, with the most rain falling in spring and the early months of summer. Average yearly precipitation is 40 inches. Summer months typically begin in late

Winters typically begin in mid to late November and run until mid to late March with average temperatures ranging from 19 to 52 degrees Fahrenheit. Precipitation in the winter typically comes in the form of snowfall or as a wintery mix (sleet and snow) with severe snowfall events occurring occasionally. Seasonal variations in climate typically do not affect underground mining in West Virginia. However, weather events could potentially negatively impact efficiency of surface and preparation plant operations on a very limited basis and lasting less than a few days. 4.5 Infrastructure The MWV Surface Business Unit has sources of water, power, personnel, and supplies readily available for use. Personnel have historically been sourced from the surrounding communities in Raleigh, Fayette and surrounding Counties, and have proven to be adequate in number to conduct mining operations. As mining is common in the surrounding areas, the workforce is generally familiar with mining practices, and many are experienced miners. Water is sourced locally from public water sources or rivers, and electricity is sourced from Appalachian Power, a subsidiary of American Electric Power (AEP). The service industry in the areas surrounding the mine operations has historically provided supplies, equipment repairs and fabrication, etc. The Kingston Preparation Plant processes MWVS coal and is capable to shipping through the Pax Loadout or by barge on the Kanawha River. Pax Loadout services consumers with raw and washed coal via the CSX railroad. Alpha’s Marfork Preparation Plant processes some MWVS coal and services consumers with washed coal, which is transported via the adjacent CSX rail line at the loadout. Haul roads, primary roads, and conveyor belt systems account for transport from the various mine sites to both surface plant facilities. 5 History 5.1 Previous Operation The MWV Surface property involves a complex combination of previous ownership. Coal mining in the area occurred for nearly a century. Predecessors of Alpha, namely Alpha Natural Resources (Alpha) and Massey Energy (Massey) previously held mining rights on much of the Property. 5.2 Previous Exploration Extensive exploration in the form of subsurface drill efforts has been carried out on the property by numerous entities, most of which efforts were completed prior to the inception of Alpha. Diamond core and rotary drilling are the primary types of exploration on the Property. Data for correlation and mining conditions are derived from core descriptions and geophysical logs (e-logging). Coal sample, quality analyses were also employed during the core-exploration process. Development of this report included an assessment of over 1,500 locations of coal measurements, largely comprised of exploration drill holes which often include several coal intercepts. In mine data measurements are included also. Alpha Metallurgical Resources, Inc.

Geophysical logging was typically performed by outside logging firms. MM&A, via its Geophysical Logging Systems subsidiary, has logged a significant number of the past exploration holes, and currently logs most of the recent drilled holes. 6 Geological Setting, Mineralization and Deposit 6.1 Regional, Local and Property Geology The Property lies in the Central Appalachian Coal basin in the Appalachian Plateau physiographic province. The coal deposits in the eastern U.S. are the oldest and most extensively developed coal deposits in the country. The coal deposits on the Property are Carboniferous in age, being of the Pennsylvanian system. Overall, these Carboniferous coals contain two-fifths of the US’s bituminous coal deposits and extend over 900 miles from northern Alabama to Pennsylvania and are part of what is known as the Appalachian Basin. The Appalachian Basin is more than 250 miles wide and, in some portions, contains over 60 coal seams of varying economic significance. Strata on the Property are mostly of the Pennsylvanian-age Kanawha Formation and the older, lower Sewell seam is part of the New River Formation of the Pottsville Series. The rock formations between the coal seams are characterized by large proportions of sandstone interspersed with shale units. Coal seams with remaining reserve or resource potential evaluated within this TRS include, in descending stratigraphic order the: Upper, Middle and Lower Clarion; Stockton, Upper Coalburg, Coalburg, Lower Coalburg, Upper Winifrede Rider, Upper Winifrede, Winifrede, Lower Winifrede, Upper Chilton A, Middle Chilton A , Chilton A Upper Split, Chilton A Lower Split, Chilton A, Chilton Rider, Upper Chilton, Lower Chilton, Chilton, Upper Hernshaw, Lower Hernshaw, Upper Cedar Grove Upper Split, Upper Cedar Grove Lower Split, Middle Cedar Grove, Lower Cedar Grove Upper Split, Lower Cedar Grove, Peerless Upper Split, Peerless Lower Split, Peerless C, Upper No. 2 Gas, Lower No. 2 Gas, Powellton, Lower Powellton, Powellton Lower Split, Powellton Lower Split Upper, Upper Eagle Rider 2, Powellton Lower Split Lower, Upper Eagle Rider, Upper Eagle, Eagle A, Eagle Upper Split, Eagle Lower Split, Eagle, Little Eagle, Little Eagle Lower Split, War Eagle, Glen Alum Tunnel Upper Split, Glen Alum Tunnel Douglas and Sewell seams. 6.2 Mineralization The generalized stratigraphic columnar section in Figure 6-1 and Figure 6-2 demonstrates the vertical relationship of the principal coal seams and rock formations on the Workman Creek and Kingston Properties.

Due to the long history of mining in the region high value of these coking coals, all the seams have been extensively mined in the past. The coal seams reach the highest structural elevations along the southeastern margin of the Property, generally dipping toward the northwest. The surface mine seams and the Douglas seam are all situated above drainage or near and are therefore accessible via outcrop. The Sewell seam is below drainage and has not been developed. The rock formations between the coal seams are characterized mainly by sandstone and shale units interspersed throughout.

Statement of Coal Resources and Reserves for the Mid-West Virginia Surface Business Unit in Accordance with United States SEC Standards as of December 31, 2021 Central Appalachian Coal Basin West Virginia, USA MARSHALL MILLER & ASSOCIATES, INC. 21 7 Exploration 7.1 Nature and Extent of Exploration The Property has been extensively explored by subsurface drilling efforts carried out by numerous entities, most of which were completed prior to ownership by Alpha. Diamond core and rotary drilling are the primary types of exploration on the Property. Diamond core drilling produces rock core samples from the hole. Data for coal bed correlations and strata mining conditions are derived from core descriptions and geophysical logging (e-logging). Geophysical logs are produced from a probe that surveys the drill hole void. Rock stratum types are interpreted from log signatures produces from the probe which commonly include a hole caliper, rock density and gamma readings. Coal-quality analyses were also employed during the core-exploration process. Drill records indicate that independent contract drilling operators have typically been engaged to carry out drilling on the Property. Geophysical logging was typically performed by outside logging firms. MM&A, via its Geophysical Logging Systems subsidiary, has logged a significant number of the past exploration holes, and currently logs most of the recently drilled holes. The Location of the drilling is shown on the maps included in Appendix C. The concentration of exploration varies slightly across the Property. Drilling on the Property is typically sufficient for delineation of potential surface and highwall miner benches, and deep mineable seams. Core logging is carried out by professional geologists in cases where roof and floor strata are of particular interest and in cases where greater resolution and geologic detail are needed. However, most drill hole data comes from simplified driller’s logs, which lack details regarding geotechnical conditions and specific geology, making correlations and floor and roof conditions difficult to determine. Geophysical logging (e-logging) techniques, by contrast, document specific details useful for geologic interpretation and mining conditions. Given the variability of data-gathering methods employed, definitive mapping of future mining conditions may not be possible, but projections and assumptions can be made within a reasonable degree of certainty. A significant effort was put into verifying the integrity of the database. Once this was established, stratigraphic columnar sections were generated using cross-sectional analysis to establish or confirm coal seam correlations. Forty-two individual coal seams or splits were identified, correlated, and modelled for resource/reserve potential in the MWV Surface Business Unit. A typical cross-section is shown in Figure 7-1. Alpha Metallurgical Resources, Inc. Statement of Coal Resources and Reserves for the Mid-West Virginia Surface Business Unit in Accordance with United States SEC Standards as of December 31, 2021 Central Appalachian Coal Basin West Virginia, USA MARSHALL MILLER & ASSOCIATES, INC. 22 Figure 7-1: MWVS Cross-Section Due to the long history of exploration by various parties on the Property, a wide variety of survey techniques exist for documentation of data point locations. Many of the older exploration drill holes appear to have been located by survey and more recently completed drill holes are often located by high-resolution Global Positioning System (GPS) units. However, some holes appear to have been approximately located using USGS topography maps or other methods which are less accurate. Therefore, discretion had to be used regarding the accuracy for the location and ground surface
Alpha Metallurgical Resources, Inc. Statement of Coal Resources and Reserves for the Mid-West Virginia Surface Business Unit in Accordance with United States SEC Standards as of December 31, 2021 Central Appalachian Coal Basin West Virginia, USA MARSHALL MILLER & ASSOCIATES, INC. 23 elevation of some of these older drill holes. In instances where a drill hole location (or associated coal seam elevations) appeared to be inconsistent with the overall structural trend (or surface topography for surface-mineable areas), the data point was not honored for geological modeling. Others with apparently minor variances were adjusted or then used by MM&A. Surveying of the underground and surface mined areas has been performed by the mine operators and/or their consulting surveyors. By assignment, MM&A did not verify the accuracy or completeness of supplied mine maps but accepted this information as being the work of responsible engineers and surveyors, as required by both State and Federal Law. MM&A compiled comprehensive topographic map files by selecting the best available aerial mapping for each area. In the case of active surface mines, digital flown topography was utilized to reference original seam outcrop positions. 7.2 Drilling Procedures Core drilling methods utilize NX-size (21/8 inch) or similar-sized core cylinders to recover core samples, which can be used to delineate geologic characteristics, and for coal quality testing and geotechnical logging. For the cored holes, the geophysical logs are especially useful in verifying the percent of core recovery of both the coal samples (for assurance that sample is representative of the full seam) and of the roof and floor rock samples (for evaluating ground control characteristics of deep mineable coal seams). In addition to the core holes, rotary drilled holes also exist on the Property. Data for the rotary drilled holes is mainly derived from downhole geophysical logs, which are used to interpret coal and rock thickness and depth since logging of the drill cuttings is not reliable in this application. A wide variety of core-logging techniques exist for the Property. For many of the core holes, the primary data source is a generalized lithology description by the driller, typically supplemented by a more detailed core log completed by a geologist. These drill logs were provided to MM&A collectively as a geological database. MM&A geologists were not involved in the production of original core logs but did perform a basic check of drill records and information within the provided database. Where geophysical logs for such holes are available, they were used by MM&A geologists to verify the coal thickness and core recovery of relevant seams. 7.3 Hydrology Hydrologic testing and forecasting are necessary parts of the permitting process and as such are routinely considered in the mine planning process. MM&A is not aware of any significant hydrologic impacts being experienced at any currently active deep mines or active surface mines. Future mining is projected to occur in areas exhibiting similar hydrogeological conditions as past mining. Based upon the successful history of the operation with Alpha Metallurgical Resources, Inc. Statement of Coal Resources and Reserves for the Mid-West Virginia Surface Business Unit in Accordance with United States SEC Standards as of December 31, 2021 Central Appalachian Coal Basin West Virginia, USA MARSHALL MILLER & ASSOCIATES, INC. 24 regards to hydrogeological features, MM&A assumes that the operation will not be hindered by such issues in the future. 7.4 Geotechnical Data Life-of-Mine (LOM) Mining plans for potential underground mines were developed by MM&A through incorporation of budget maps from Alpha. Pillar stability was tested by MM&A using the Analysis of Coal Pillar Stability (ACPS) program that was developed by the National Institute for Occupational Safety and Health (NIOSH). MM&A reviewed the results from the ACPS analysis and considered it in the development of the LOM plan. Coal and rock strengths from core testing are used to verify the empirical assumptions integral to ACPS. 8 Sample Preparation Analyses and Security 8.1 Prior to Sending to the Lab Most of the coal samples related to exploration drilling activities have been obtained from the Property by subsurface exploration using core drilling techniques. The protocol for preparing and testing the samples has varied over time and is not well documented for the older holes drilled on the Property. Typical US coal sampling technique from core drilling is for the coal core sample, once recovered from the core barrel, to be measured and described into a log, then wrapped in a sealed plastic sleeve and placed into a covered wooden core box, which is the length of the sample so that the core can be delivered to a laboratory in relatively intact condition and with original moisture content. The core identification number and the depth are scribed on the sample box lid to identify the sample. This process has been the norm for both historical and ongoing exploration activities at MWVS. This work is typically performed by the supervising driller, geologist, or company personnel. Samples are most often delivered to the company by the driller after each shift or acquired by company personnel or representatives. Most of the coal core samples were obtained by previous operators on the Property. MM&A did not participate in the collection, sampling, and analysis of the majority of core samples within the exploration database. However, it is reasonable to assume, given the professional level of the previous operators, that these samples were generally collected and processed under industry best-practices. This assumption is based on MM&A’s familiarity with the operating companies and the companies used to perform the analysis. Additionally, specific to Alpha’s MWVS surface operations, a significant dataset was made available related to in-pit quality measurements used during the mining process as a predictive measure prior to mining. This robust dataset is generally based upon bulk or grab samples obtained by employees of Alpha prior to the extraction of coal in surface mined pits or in stockpiles. The information contained
Alpha Metallurgical Resources, Inc. Statement of Coal Resources and Reserves for the Mid-West Virginia Surface Business Unit in Accordance with United States SEC Standards as of December 31, 2021 Central Appalachian Coal Basin West Virginia, USA MARSHALL MILLER & ASSOCIATES, INC. 25 in the dataset does not include a surveyed location point, as the information is generally only relied upon in the short term for assistance in coal blending procedures. 8.2 Lab Procedures Coal quality testing related to exploration drilling has been performed over many years by operating companies using different laboratories and testing regimens. Some of the samples have raw analyses and washability analysis on the full seam (with coal and rock parting layers co-mingled) and are mainly useful for characterizing the coal quality for projected production from underground and highwall mining. Other samples have coal and rock analyzed separately, the results of which can be manipulated to forecast either surface or underground mining quality. Care has been taken to use only those analyses that are representative of the coal quality parameters for the appropriate mining type for each sample. Standard procedure upon receipt of core samples by the testing laboratory is to log the depth and thickness of the sample, then perform testing as specified by a representative of the operating company. Each sample is then analyzed in accordance with procedures defined under American Society for Testing and Materials (ASTM) standards including, but not limited to; washability (ASTM D4371); ash (ASTM D3174); sulfur (ASTM D4239); Btu/lb. (ASTM D5865); volatile matter (ASTM D3175); and Free Swell Index (FSI) (ASTM D720). Specific to the aforementioned pit-quality sampling and associated datasets, laboratory analysis includes both short proximate analysis and at times, detailed metallurgical characteristics. The dataset contains a combination of raw and washed samples. 9 Data Verification 9.1 Procedures of Qualified Person MM&A reviewed the Alpha-supplied digital geologic database which consists of data records including drill hole information for holes that lie within and adjacent to the Property along with records for numerous supplemental coal seam thickness measurements, mainly in mine measurements from underground mine maps. Once the initial integrity of the database was established, stratigraphic columnar sections were generated to use cross-sectional analysis to establish or confirm coal seam correlations. The stratigraphic column correlation method provides a view of seam depths, lithologic strata and thickness intervals to over and underlying seams. Geophysical logs were used wherever available to assist in confirming the seam correlation and to verify proper seam depths, thickness measurements and recovery of coal samples. After establishing and/or verifying proper seam correlation for all seam the database was used in the geologic model process. Seam thickness, base-of-seam elevation, roof and floor lithology data control, Alpha Metallurgical Resources, Inc. Statement of Coal Resources and Reserves for the Mid-West Virginia Surface Business Unit in Accordance with United States SEC Standards as of December 31, 2021 Central Appalachian Coal Basin West Virginia, USA MARSHALL MILLER & ASSOCIATES, INC. 26 and overburden maps were independently generated for use in the mine planning process. Maps with seam control data plus geological cross-sections were generated to represent the seam correlations and data integrity. Forty-two individual coal seams or splits were identified, correlated, and modelled for resource/reserve potential in the MWV Surface Business Unit. Coal quality data was analyzed and summarized by MM&A’s team of geologists and engineers. Quality was provided by Alpha in various database formats, laboratory data sheets, and also obtained directly from MM&A’s files. Care was taken to ensure that sampled data was representative of the mineable section. In instances where minimal representative data was noted, geological tonnages were estimated based upon applying assumed densities of coal and non-coal material to thicknesses expressed in geological database files. 9.2 Limitations As with any exploration program, localized anomalies, such as a thin coal area or poor mining conditions, cannot always be discovered. The greater the density of the samples taken, the less the risk. Once an area is identified for inclusion in the mine plan, additional samples are taken to help reduce the risk in specific areas. In general, provision is made in the mine planning portion of the study to allow for localized anomalies that are typically classed more as a nuisance than a hinderance. 9.3 Opinion of Qualified Person Sufficient data has been obtained through various exploration and sampling programs and mining operations to support the geological interpretations of seam structure and thickness for coal horizons situated on the MWVS Property. The Property data is of sufficient quantity and reliability to reasonably support the coal resource and coal reserve estimates in this TRS. 10 Mineral Processing and Metallurgical Testing 10.1 Testing Procedures Basic chemical analyses (both raw and washed quality), petrographic data, rheological data and ash, ultimate and sulfur analysis are available but not summarized for this filing. Available coal quality data sourced from MM&A’s vaults (associated with former projects for Alpha and its predecessors) was tabulated by resource area in a Microsoft® EXCEL workbook. Such data contained laboratory sheets which MM&A utilized to confirm that sampled intervals were representative of geological models and confirm that appropriate laboratory procedures were utilized to derive raw and clean coal parameters. Additionally, Alpha provided MM&A with a database of its own in-house coal quality information which did not include backup laboratory information or sampled intervals. MM&A compared wash recovery values from Alpha’s dataset to proximal holes with wash recovery data in MM&A’s dataset and calculated estimates of wash recovery based upon the relative percentages of coal and rock from lithologic descriptions. In general, MM&A found that Alpha’s dataset was representative and appropriate for inclusion in coal quality summaries. Quality tables also provide
Alpha Metallurgical Resources, Inc. Statement of Coal Resources and Reserves for the Mid-West Virginia Surface Business Unit in Accordance with United States SEC Standards as of December 31, 2021 Central Appalachian Coal Basin West Virginia, USA MARSHALL MILLER & ASSOCIATES, INC. 27 basic statistical analyses of the coal quality datasets, including average value; maximum and minimum values; and the number of samples available to represent each quality parameter of the seam. Coal samples that were deemed by MM&A geologists to be unrepresentative were not used for statistical analysis of coal quality, as documented in the tabulations. The amount and areal extent of coal sampling for geological data is generally sufficient to represent the quality characteristics of the coal horizons and allow for proper market placement of the subject coal seams. For some of the coal deposits there are considerable laboratory data from core samples that are representative of the full extent of the resource area; and for others there are more limited data to represent the resource area. For example, in the active operations with considerable previous mining, there may be limited quality data within some of the remaining resource areas; however, in those cases the core sampling data can be supplemented with operational data from mining and shipped quality samples representative of the resource area. 10.2 Relationship of Tests to the Whole The extensive sampling and testing procedures typically followed in the Coal Industry result in an excellent correlation between samples and Marketable product. Pit analyses of the coal from MWVS were reviewed to verify that the coal quality and characteristics were as expected. The MWVS Property has a long history of saleable production, under various owners, in the Mid-Volatile and High-volatile metallurgical and thermal markets, confirming exploration results. In select instances, those areas which did not contain exploration information inclusive of coal quality analysis but were located relatively adjacent to active producing areas and/or areas which contained coal quality information were downgraded to a “probable” classification. Based upon the extensive production history locally and regionally, the report authors deemed this process acceptable. 10.3 Lab Information Each sample is analyzed at area Laboratories that operate in accordance with procedures defined under ASTM standards including, but not limited to; washability (ASTM D4371); ash (ASTM D3174); sulfur (ASTM D4239); Btu/lb. (ASTM D5865); volatile matter (ASTM D3175); and Free Swell Index (FSI) (ASTM D720). 10.4 Relevant Results No critical factors have been found that would adversely affect the recovery of the Reserve. Any quality issues that occur, either localized or generally are accounted for in the Marketing Study done for this TRS. Alpha Metallurgical Resources, Inc. Statement of Coal Resources and Reserves for the Mid-West Virginia Surface Business Unit in Accordance with United States SEC Standards as of December 31, 2021 Central Appalachian Coal Basin West Virginia, USA MARSHALL MILLER & ASSOCIATES, INC. 28 11 Mineral Resource Estimates MM&A independently created geologic models to define the coal resources at MWVS. Coal resources were estimated as of December 31, 2021. 11.1 Assumptions, Parameters and Methodology Geological data was imported into Carlson Mining® (formerly SurvCADD®) geological modelling software in the form of Microsoft® Excel files incorporating, drill hole collars, seam and thickness picks, bottom seam elevations and raw and washed coal quality. These data files were validated prior to importing into the software. Once imported, a geologic model was created, reviewed, and verified- with a key element being a gridded model of coal seam thickness. Resource tons were estimated by using the seam thickness grid based on each valid point of observation and by defining resource confidence arcs around the points of observation. Points of observation for Measured and Indicated confidence arcs were defined for all valid drill holes that intersected the seam using standards deemed acceptable by MM&A based on a detailed geologic evaluation and a statistical analysis of drill holes within the projected reserve areas as described in Section 11.1.1. The geological evaluation incorporated an analysis of seam thickness related to depositional environments, adjacent roof and floor lithologies, and structural influences. After validating coal seam data and establishing correlations, the seam thickness, coal thickness and elevation for seams of economic interest were used to generate a geologic model. Local geologic and physical conditions were incorporated into the model where mineability and or mining costs could be affected by the conditions. Both coal thickness and quality data are deemed by MM&A to be reasonably sufficient within the resource areas. Therefore, there is a reasonable level of confidence in the geologic interpretations required for coal resource determination based on the available data and the techniques applied to the data. Table 11-1 below provides the geological mapping and coal tonnage estimation criteria used for the coal resource and reserve evaluation. These cut-off parameters have been developed by MM&A based on its experience with the Alpha Property and are typical of mining operations in the Central Appalachian coal basin. This experience includes technical and economic evaluations of numerous properties in the region for the purposes of determining the economic viability of the subject coal reserves.

Final classification of coal reserve is made based on the pre-feasibility evaluation. 11.1.1 Geostatistical Analysis MM&A completed a geostatistical analysis on drill holes within the reserve boundaries to determine the applicability of the common United States classification system for measured and indicated coal resources. Historically, the United States has assumed that coal within ¼-mile (1,320 feet) of a point of observation represents a measured resource whereas coal between ¼-mile (1,320 feet) and ¾-mile (3,960 feet) from a point of observation is classified as indicated. Inferred resources are commonly assumed to be located between ¾-mile (3,960 feet) and 3 miles (15,840 feet) from a point of observation. Per SEC regulations, only measured and indicated resources may be considered for reserve classification, respectively as proven and probable reserves. MM&A performed a geostatistical analysis test of the MWVS, Workman Creek Little Eagle Seam data set using the Drill Hole Spacing Analysis (DHSA) method. This method attempts to quantify the uncertainty of applying a measurement from a central location to increasingly larger square blocks and provides recommendations for determining the distances between drill holes for measured, indicated, and inferred resources.
Alpha Metallurgical Resources, Inc. Statement of Coal Resources and Reserves for the Mid-West Virginia Surface Business Unit in Accordance with United States SEC Standards as of December 31, 2021 Central Appalachian Coal Basin West Virginia, USA MARSHALL MILLER & ASSOCIATES, INC. 31 To perform DHSA the data set was processed to remove any erroneous data points, clustered data points, as well as directional trends. This was achieved through the use of histograms, as seen in Figure 11-1, color coded scatter plots showing the geospatial positioning of the borings, Figure 11-2, and trend analysis. Figure 11-1: Histogram of the Total Seam Thickness for the Little Eagle Seam Present in the MWVS Business Unit Figure 11-2: Scatter plot of the Total Seam Thickness for the Little Eagle Seam Present in the MWVS Business Unit Following the completion of data processing, a variogram of the data set was created, Figure 11-3. The variogram plots average square difference against the separation distance between the data pairs. The separation distance is broken up into separate bins defined by a uniform lag distance (e.g., for a lag distance of 500 feet the bins would be 0 – 500 feet, 501 – 1,000 feet, etc.). Each pair of data points that are less than one lag distance apart are reported in the first bin. If the data pair is further apart than one lag distance but less than two lag distances apart, then the variance is reported in the second bin. The numerical average for differences reported for each bin is then plotted on the variogram. Care was taken to define the lag distance in such a way as to not overestimate any nugget effect present in the data set. Lastly, modeled equations, often spherical, gaussian, or exponential, are applied to the variogram in order to represent the data set across a continuous spectrum. Alpha Metallurgical Resources, Inc.

This value estimates the variance from applying a single central measurement to increasingly larger square blocks. Care was taken to ensure any nugget effect present was added back into the data. This process was repeated for each test block size. The final step of the process is to calculate the global estimation variance. In this step the number square blocks that would fit inside the selected study area is determined for each block size that was investigated in the previous step. The estimation variance is then divided by the number of blocks that would fit inside the study area for each test block size. Following this determination, the data is then transformed back to represent the relative error in the 95th-percentile range. Figure 11-4 shows the results of the DHSA performed on the Little Eagle seam data for the MWV Surface Business Unit. DHSA provides hole to hole spacing values, these distances need to be converted to radius from a central point in order to compare to the historical standards. A summary of the radius data is shown in Table 11-3. DHSA prescribes measured, indicated, and inferred drill hole spacings be determined at the 10-percent, 20-percent, and 50-percent levels of relative error, respectively.

The Exponential model recommends using a radius of 0.37 miles for measured resources compared to the historical value of 0.25 miles. With respect to indicated resources the DHSA- recommended drill hole spacing is slight less than the historical standards although within the margin of precision. The Exponential model recommends using a radius 0.69 miles, while the Gaussian and Spherical models recommend a radius of 0.63 and 0.69 miles, respectively compared against the historical radius of 0.75 miles. These results have led the QP’s to report the data following the historical classification standards as outlined in USGS Circular 891, rather than use the results of the DHSA. 11.2 Resources Exclusive of Reserves The MWVS Properties contain resource blocks of surface seams which were not deemed to exhibit reserve potential at the time of the study. These resources, identified as resources exclusive of reserves, exist in the Eagle 2 permit in the Lower Winifrede bench. Reasons which may preclude elevation of resources to reserves include, but are not limited to: Alpha Metallurgical Resources, Inc. Statement of Coal Resources and Reserves for the Mid-West Virginia Surface Business Unit in Accordance with United States SEC Standards as of December 31, 2021 Central Appalachian Coal Basin West Virginia, USA MARSHALL MILLER & ASSOCIATES, INC. 34 1. Limited availability of quality information to document coal seam market characteristics. > The Lower Winifrede and above coal seams in the Eagle 2 Permit lack coal quality information and are deemed a resource. 2. Limited a drillhole density and/or coal seam definition. 3. Drill hole spacing is relatively wide spaced in the Sewell resource area. Due to the lack of seam definition, the resource is classified as indicated. Mineability constraints due to over/under mining, underground conditions, and physical locations that would have negative influence on the mineability of the coal. > The Sewell resources area is bound on the east side by existing close Sewell mines. Based on the mine maps, it appears entries were driven toward and into the resource block and then stopped. It is likely coal thickness and/or other geologic conditions were encountered that limited the advance into the resource area. 11.2.1 Initial Economic Assessment MM&A completed an initial economic assessment to determine the potential economic viability of resources exclusive of reserves. MM&A applied relevant technical factors to estimate potential saleable tons without the resource blocks, should the resources be extracted via deep, continuous mining methods. MM&A developed cash cost profiles for the resource blocks, including direct cash costs (labor, supplies, roof control, maintenance and repair, power, and other); washing, trucking, materials handling, general and administrative, and environmental costs; and indirect cash costs (royalties, production taxes, property tax, insurance). Costs were developed based off relevant cost drivers (per-ft, per-raw-ton, per-clean-ton). Additionally, MM&A estimated capital costs to access resources. Capital costs associated with mine developed were amortized across the resource’s potential saleable tonnages). Additional non-cash items (depreciation of equipment and depletion) and cash costs were compared to an assumed sale price of $120 per ton netback FOB loadout (approximately $169 per ton U.S. East Coast basis) for Mid Vol markets and $100 per ton netback FOB loadout (approximately $141 per ton U.S. East Coast basis) for thermal markets. This resource assumed sales value was developed as a premium to the market-based reserve sales value to properly estimate the sales related expenses should these resources be extracted during higher-than-average market conditions. Pricing used for the primary product was selected by the QP and deemed reasonable based on a review of historical average pricing for the MWVS Business Unit coal products over the past 5 years. Results of the analysis are shown below and demonstrate potential profitability on a fully loaded cost basis. Detailed summaries are shown in Appendix B.

See Appendix A for detailed breakdown. 11.4 Qualified Person’s Opinion While there is some stratigraphically controlled seam-thickness variability due to seam splitting, sand channels, etc., MM&A geologists and engineers modeled the deposit and resource areas to reflect realistic mining scenarios, giving special consideration to seam thickness, floor and roof conditions, mining equipment, etc. This statistical study demonstrates that for each configuration of mineable seams, the classification system of measured (0 – ¼ mile), indicated (¼ to ¾ mile), and inferred (¾ to 3 miles) is reasonably adequate to predict seam thickness variation for modeling and mining purposes. Based on MM&A’s geostatistical analysis, it would be possible to extend the measured arcs slightly beyond historically accepted practices due to consistent geological settings. The QP’s have again elected not to extend arc distances, introducing a level of conservatism in the measured coal classification. Based on the data review, the attendant work done to verify the data integrity and the creation of an independent Geologic Model, MM&A believes this is a fair and accurate representation of the MWVS coal resources.

It is based on appropriate assessment and studies in consideration of and adjusted for reasonably assumed modifying factors. These assessments demonstrate that extraction could be reasonably justified at the time of reporting. > Probable Coal Reserves are the economically mineable part of an indicated coal resource, and in some circumstances a measured coal resource, adjusted for diluting materials and allowances for losses when the material is mined. It is based on appropriate assessment and studies in consideration of and adjusted for reasonably assumed modifying factors. These assessments demonstrate that extraction could be reasonably justified at the time of reporting. Upon completion of delineation and calculation of coal resources, MM&A generated a LOM plan for MWV Surface. The footprint of each reserve area is shown on the maps in Appendix C. The Mine plan was generated based on 5-year budget mine plans provided by Alpha and supplemented with additional projections by MM&A to reflect LOM plans that honor property control limits, geologic mapping, or other factors determined during the evaluation. Carlson Mining software was used to generate the LOM plan for MWVS. The mine plan was sequenced based on productivity schedules provided by Alpha. MM&A judged the productivity estimates and plans to be reasonable based on experience and current industry practice. Raw, ROM production data outputs from LOM plan sequencing were processed into Microsoft® EXCEL spreadsheets and summarized on an annual basis for processing into the economic model. Average seam densities were estimated to determine raw coal tons produced from the LOM plan. Average mine recovery and wash recovery factors were applied to determine coal reserve tons. Coal reserve tons in this evaluation are reported on a moist, saleable product basis with 4.5% moisture for surface mined reserves and 6.0% for deep mine reserves. Pricing data as provided by Alpha is described in Table 16-2. The pricing data assumes a flat-line long term realization average of $144 per short ton port loading, with an average of $102.26 netback pricing reflective of the mid-volatile product, $144 per short ton port loading with an average of $111.29 per short ton netback pricing reflective of the low-volatile product, and $138 per short ton port loading, with an average of $108.08 netback pricing reflective of the high-volatile product currently sold at Alpha Metallurgical Resources, Inc. Statement of Coal Resources and Reserves for the Mid-West Virginia Surface Business Unit in Accordance with United States SEC Standards as of December 31, 2021 Central Appalachian Coal Basin West Virginia, USA MARSHALL MILLER & ASSOCIATES, INC. 38 MWVS. A portion of the surface mine production is also thermal product which assumes a flat-line long term realization of $76 per short ton with an average of $66.68 per ton netback pricing. The LOM blended average netback pricing for the MWVS reserves is $95.97 per ton. These estimates are based on long term pricing published by third party sources and adjusted for quality and transportation. A large majority of the coal sold by Alpha and their MWVS business group is shipped internationally as part of blended products from other business units within Alpha or sourced from other companies. These netback adjustments reflect these additional costs carried after the products leave the MWVS business unit. The coal resource mapping and estimation process, described in the report, was used as a basis for the coal reserve estimate. Proven and probable coal reserves were derived from the defined coal resource considering relevant processing, economic (including technical estimates of capital, revenue, and cost), marketing, legal, environmental, socio-economic, and regulatory factors and are presented on a moist, recoverable basis. As is customary in the US, the categories for proven and probable coal reserves are based on the distances from valid points of measurement as determined by the QP for the area under consideration. For this evaluation, measured resource, which may convert to a proven reserve, is based on a ¼-mile radius from a valid point of observation. Points of observation include exploration drill holes, and mine measurements which have been fully vetted and processed into a geologic model. The geologic model is based on seam depositional modeling, the interrelationship of overlying and underlying strata on seam mineability, seam thickness trends, the impact of seam structure, intra-seam characteristics, etc. Once the geologic model was completed, a statistical analysis, described in Section 11.1.1 was conducted and a ¼-mile radius from a valid point of observation was selected to define Measured Resources. Likewise, the distance between ¼ and ¾ of a mile radius was selected to define Indicated Resources. Indicated Resources may convert to Probable Reserves. Inferred Resources (greater than a ¾-mile radius from a valid point of observation) have been excluded from Reserve consideration. 12.2 Mineral Reserves MWVS Business Unit reserves were derived from multiple coal seams of Figure 7-1 located on the Property. Reserves are estimated for both surface and underground mining. Surface reserves were derived for two units Workman Creek, and Kingston. Each account for coal reserves from multiple seams. Underground reserves were derived from two seams. The underground accessed seams include the Douglas seam at the active Kingston 2 mine; the Sewell seam located below drainage east

Demonstrated reserve tons are listed in the discussion below. Table 12-3 shows the demonstrated tonnage by Proven and Probable status. 12.2.1 Surface Reserves The two surface units of the MWVS, Kingston and Workman Creek operations are both active mines with contour and highwall miner reserve. Estimated LOM average mine ratios bank cubic yards per ton (BCY/Ton) do not exceed 20 to 1 for the reserve estimates. Cross sections through drill holes with lithologic records and seam correlation tie lines have been prepared for each surface reserve and are available upon request. 12.2.1.1 Workman Creek Surface Demonstrated reserve at Workman Creek is comprised of 27.6 million surface mine tons and 3.8 million highwall miner tons from 25 different coal seams. An additional 8 seams are considered resource due to a lack of quality data. Workman Creek reserves consists of six permit areas that are adjacent to each other and are centered around the Workman Creek office and surface facility area.

All of the permits are active to varying degrees with the exception of the Eagle 2 permit. The reserves within Eagle 2 permit may increase if the permit’s proposed hollow fills within Sycamore branch receive the necessary US Army Corps of Engineers’ (USACE) 404 permit. Lower elevation seams within the permit require the hollow fills for excess spoil storage. The reserves of the Eagle 2 permit are presently limited to upper seams that can be backfilled and can obtain excess spoil storage room from adjacent permits. 12.2.1.2 Kingston Surface Demonstrated reserve at Kinston surface is comprised of 19.5 million surface mine tons and 2.5 million highwall miner tons from 30 different coal seams for permitted and non-permitted reserve. Kingston surface consists of two permitted areas and one pending permit area. The mine permit areas are adjacent to one another with mine permits. One Kingston permit has an active surface mine.

These contours will likely be associated with future hollow fills and/or in close proximity to them. 12.2.2 Underground Reserves Underground reserves of the MWVS are associated with Kingston operation. There are three underground reserve areas. The Kingston 2 and 10 mines and associated reserves that extract mid- volatile coal from the Douglas seam. The Sewell seam reserve is below drainage and located east of the surface mines. 12.2.2.1 Kingston 2 - Douglas Seam Douglas reserves include 0.7 M clean recoverable tons remaining in the active Kingston 2 Mine. The Douglas seam is commonly one coal bench with localized area of thin shale partings. Seam thickness average 2.5 feet in the Kingston 2 Mine reserve. Roof and floor rock is generally shale that makes the mine horizon a cuttable unit. The run-of-mine (ROM) coal is belted to the Kingston Preparation Plant prior to shipping to the customer. 12.2.2.2 Kingston 10 – Douglas Seam Douglas reserves include 0.7 M clean recoverable tons in the future Kingston 10 Mine, which will require a new face-up and portals. Seam thickness average 2.6 feet in the Kingston 10 Mine reserve. The Douglas seam appears to begin to split on the west side of the reserve area. The split thickness may define the reserve limit. 12.2.2.3 Sewell Seam The Sewell seam reserve is located near the community of Pax in Fayette County, West Virginia. The Sewell seam demonstrated reserves are 9.1 M clean recoverable tons. The reserve is classified as a Probable reserve due to the lack of metallurgical quality. The seam is below drainage and the overburden ranges from 200 feet in the lowest valley bottoms to over 900 feet under the highest ridge tops. The Paint Creek Lineament is a north-south trending zone generally following the western reserve boundary with most tons found east of the lineament. The Sewell seam is known to be gassy and influenced by horizontal stress that would be managed by ventilation and mine design. In addition, multiple combinations of mineable Sewell seam benches A, B, C and D exist throughout the reserve. The seam consists of multiple coal benches (1 to 4 benches) and seam thickness ranges from 3 feet to 11 feet. The benches are generally depositional with limited lateral continuity where the coal thins at the margin of the deposition basin. The raised depositional areas trend north-south through the center part of the reserve and contain the most coal benches and thickest seam. Roof and floor rock is mostly shale that makes the mine horizon a cuttable unit. Alpha Metallurgical Resources, Inc.

The extent to which the coal reserves may be affected by any known environmental, permitting, legal, title, socio-economic, marketing, political, or other relevant issues has been reviewed rigorously. Similarly, the extent to which the estimates of coal reserves may be materially affected by mining, metallurgical, infrastructure and other relevant factors has also been considered. The results of this TRS define an estimated 60.7 Mt of proven and probable marketable coal reserves.

Raw quality and some volatile matter analysis not available for Workman Creek . Workman Creek surface reserves were priced at 60% High-Vol. A and 40% thermal product. Douglas seam volatile matter analysis not available. Douglas seam priced as a Mid-Vol. product, consistent with Kingston 2 production. Actual product moisture is dependent upon multiple geological factors, operational factors, and product contract specifications and can exceed 8-percent. As such, the modeled moisture values provide a level of conservatism for reserve reporting. Totals may not add due to rounding. Workman Creek Surface is modeled as 55% direct-ship and 45% washed to mimic what Alpha is doing, however without any raw quality data for the surface seams a quality composite could not be prepared. See Appendix A for detailed breakdown. In summary, Alpha controls a total of 60.7 Mt (moist basis) of marketable coal reserves at MWVS as of December 31, 2021. Of that total, 38 percent are proven, and 62 percent are probable. Due to the lack of raw coal quality information, all Workman Creek surface reserves have been classified as Probable even though it is an active operation with sales into the thermal and metallurgical markets. Of the 60.7 Mt, 0.7 Mt are owned, and 60.1 Mt are leased coal reserves. Of the total, 44.0 Mt are surface mineable, 6.2 Mt are highwall mineable, and 10.5 Mt are underground mineable. Marketable coal reserves are 13.7 Mt are thermal and 47.1 Mt are metallurgical. Of the total, 51.0 Mt are assigned, and the remaining 9.8 Mt are unassigned.
Alpha Metallurgical Resources, Inc. Statement of Coal Resources and Reserves for the Mid-West Virginia Surface Business Unit in Accordance with United States SEC Standards as of December 31, 2021 Central Appalachian Coal Basin West Virginia, USA MARSHALL MILLER & ASSOCIATES, INC. 43 12.4 Qualified Person’s Opinion The estimate of coal reserves was determined in accordance with the new SEC Guidelines which will become effective for the first fiscal year falling on or after January 1, 2021. The LOM mining plan for MWV Surface was prepared to the level of preliminary feasibility. Mine projections were prepared, and timing scheduled to match production with coal seam characteristics. Production timing was carried out from current locations to depletion of the coal reserve area. Coal reserve estimates could be materially affected by the risk factors described in Section 22.2. Based on the Preliminary Feasibility Study and the attendant Economic Review, MM&A believes this is a fair and accurate calculation of the MWV Surface coal reserves. 13 Mining Methods Three underground mining areas along with eight surface and highwall miner areas were modeled and tested economically. Once the Resources were calculated, mine plans were created to project operating each resource area to depletion, with crews and equipment scheduled to move to subsequent mining areas as depletion occurs. Underground mine operations are projected to be exhausted in 2035, while surface and highwall mining operations are projected to be completed in 2042. Individual mine lives range from 3 to 22 years. 13.1 Geotech and Hydrology Mining plans for potential underground mines were developed by Alpha and MM&A. Pillar stability was tested by MM&A using the Analysis of Coal Pillar Stability (ACPS) program that was developed by the National Institute for Occupational Safety and Health (NIOSH). MM&A reviewed the results from the ACPS analysis and considered it in the development of the LOM plan. Hydrology has not been an issue of concern at Alpha’s MWVS operations. Based on numerous site visits to the underground operations of the Property by the QP’s, it has been determined that this is not a significant concern. Mining of future reserves is projected to occur in areas which exhibit similar hydrogeological characteristics as those formerly mined areas. 13.2 Production Rates Operations at the MWVS operations by Alpha and its predecessors are in various stages of maturity. The mine plan and productivity expectations reflect historical performance and efforts have been made to adjust the plan to reflect future conditions. MM&A is confident that the mine plan is reasonably representative to provide an accurate estimation of coal reserves. Mine development and operation have not been optimized within the TRS.

Statement of Coal Resources and Reserves for the Mid-West Virginia Surface Business Unit in Accordance with United States SEC Standards as of December 31, 2021 Central Appalachian Coal Basin West Virginia, USA MARSHALL MILLER & ASSOCIATES, INC. 44 Carlson Mining software was used by MM&A to generate mine plans for the mineable coal seams. Mine plans were sequenced based on productivity schedules provided by Alpha, which were based on historically achieved productivity levels. All production forecasting ties assumed production rates to geological models as constructed by MM&A’s team of geologists and mining engineers. As shown in Table 13-1, the areas planned for underground mines produce coal until 2035. Clean coal production varies directly with coal thickness and anticipated mining conditions.

For each mine plan, the appropriate number of production units is selected for the resource area, and a productivity level assigned, expressed in feet of advance per unit-shift of production. The productivity is based on the equipment and personnel configuration, mining height and expected physical conditions. 13.4 Required Equipment and Personnel 13.4.1 Underground Mines 13.4.1.1 Kingston 2 Mine – Douglas Seam (Maps UG-1) Kingston 2 is an active mine and has been in production over 20 years. Two operating sections are found within the mine plan. Each production unit is supplied with two (2) continuous miners, two (2) roof bolters, four (4) shuttle cars, two (2) scoops and one (1) section feeder breaker. Four distinct portal area access the reserve boundary from coal seam contour benches. > The main portal and surface facilities are located on the east side of the valley, immediately upstream of the Kingston Preparation Plant. This facility includes the mine office, warehousing and change house facilities. > Portals are located on the west side of the valley, immediately across from the main portals. > A set of portals northeast of the preparation plant deliver run of mine coal into a stockpile that feeds the Kingston Preparation Plant. Alpha Metallurgical Resources, Inc. Statement of Coal Resources and Reserves for the Mid-West Virginia Surface Business Unit in Accordance with United States SEC Standards as of December 31, 2021 Central Appalachian Coal Basin West Virginia, USA MARSHALL MILLER & ASSOCIATES, INC. 46 > A new set of portals at Shotgun Hollow above the community of Pax have been developed. These portals provide a shorter travel distance to the working areas than the original portal locations. The basis mining concept has the continuous miner cutting coal and rock from the mine face. The continuous miner loads the run of mine material into shuttle cars which transports the material to the section feeder breaker. The feeder breaker loads the run of mine product onto the section conveyor belt and consecutive conveyor belts for haulage to the surface stockpile. Once the continuous miner has reached its maximum distance in a working face, it is trammed to another available working face to begin mining. The roof bolter machine is moved into the recently completed working face to support the roof and ribs with steel bolts and plates. The run of mine coal stockpile is located adjacent to the Kingston Preparation Plant where a reclaim conveyor transports the run of mine product for processing. The mine is nearing its end of life with one unit ending its assignment in mid-2022 and the remaining unit finishing in late 2023. Remaining reserves are found at the edges of the mineral body. 13.4.1.2 Kingston 10 Mine – Douglas Seam (Map UG-1) A small boundary area accessible from outcrop near White Oak Branch of Clear Creek has been included within the report. The Kingston 10 Mine would use one continuous miner unit from the Kingston 2 Mine as the unit becomes available. The run of mine coal would be placed into a stockpile and trucked to a processing facility before shipping to a customer. The nearest access to a preparation plant facility would be by trucking the run-of-mine coal 4.9 miles to the Workman Creek Coal Handling Facility which uses an underground mine conveyor system to transport run of mine material to the Marfork Preparation Plant. From there, the product will be processed and shipped to the market via the CSX Transportation railroad system. The operation is projected to start in the third quarter of 2022 and complete its assignment in the first quarter of 2025. 13.4.1.3 Sewell Seam Mine Sewell Mine (Map UG-2) The Sewell Seam reserve boundary will be reached by constructing a slope and two ventilation shafts for access. The slope has a grade of 15 percent and will be constructed at a width capable of supporting the mine conveyor as well as an adjacent haulage road. Projected plans include the construction of a raw coal stockpile near the slope portal which would ship the raw product to a proposed railcar loading facility. From there the coal would be transported to Alpha’s Mammoth Preparation Plant near Montgomery, West Virginia. The Mammoth Preparation Plant is serviced by the Kanawha River Railroad (KNWA), a shortline railroad owned by WATCO. Capital

The rail haul from the Pax Loadout to the Mammoth Preparation Plant would operate entirely on KNWA rail for a one-way distance of 33 miles. The proposed mine has been timed with three operating continuous miner production units. Each production unit is equipped with two (2) continuous miners, two (2) roof bolting machines, four (4) shuttle cars, two (2) mine scoops and one (1) section feeder breaker. The normal production cycle involves the continuous miner cutting coal and rock from the mine face. The continuous miner loads the run of mine material into shuttle cars which transports the material to the section feeder breaker. The feeder breaker loads the run of mine product onto the section conveyor belt and consecutive conveyor belts for haulage to the surface stockpile. Operating life of the Sewell seam mine is projected at 10 years. Alpha Metallurgical Resources, Inc.

Deep mining has taken place in the Lower Hernshaw, Middle Cedar Grove, Lower Cedar Grove, Lower 2 Gas, Powellton, Upper Eagle, Eagle Rider/Eagle A, Eagle, and Little Eagle. Previous contour and augering mining have also been documented. The present mine plan consists of six permits: Middle Fork, Collins Fork, Turkey Foot, Center Contour, Long Ridge, and Eagle #2.
Alpha Metallurgical Resources, Inc. Statement of Coal Resources and Reserves for the Mid-West Virginia Surface Business Unit in Accordance with United States SEC Standards as of December 31, 2021 Central Appalachian Coal Basin West Virginia, USA MARSHALL MILLER & ASSOCIATES, INC. 49 Mining activity consists of hydraulic shovels/ front-end loaders with rock trucks contour mining the lower seams; generating highwalls that are subsequently reclaimed by track bulldozers pushing material off upper seams. Prior to their reclamation highwall miners selectively borrow long holes in the thicker seams exposed in the highwall. Where vertical elevation differences exceed 500 ft, burden will have to be initially trucked off the mountain ridge(s). Presently excess spoil room is provided by hollow fills on the eastern and southern portion of the Workman permits. Potential for additional hollow fill space exists in Sycamore Creek, but these hollow fills have yet to be approved by the United States Army Corps of Engineers (USACE). Backfilling of mined benches is a major component of burden placement according to the mine permits. Careful operational planning will be required to ensure burden placement does not interfere with the full extraction of lower seam reserves. MM&A did not attempt to confirm burden storage capacity as presented in Workman’s permits. The active Workman Creek Coal Handling Facility (CHF) presently used to convey coals through the mountain in the No. 2 Gas seam to the Marfork preparation plant does not allow for the full contour cuts as depicted in the Center Contour permit and will likely reduce burden storage capacity along the eastern ridge line as depicted in the permit. Contour mining of the lower seams is very efficient with two or three cuts typically required until excavation limits are reached. Burden is trucked to hollow fills and/or back fill areas previously mined. Seams generally exposed during contour activity include the Upper Eagle, Eagle Rider, Eagle and Little Eagle. Track bulldozers expose the seams above the contour highwall. These seams generally include the upper and lower Powellton, upper and lower No. 2 Gas and Peerless seams. Dozers provide a very cheap, fast, and safe means of reclaiming the lower contour highwalls. Excavation and haulage of upper seam burden is actively taking place in the Middle Ridge, Collins Fork and Eagle #2 permits. It will also have to take place in the Center Contour, Turkey Foot and Long Ridge permits. To shorten haul distances, a “cut-thru” is proposed in the Long Ridge permit. The cut-thru will improve mining accessibility to the Turkey Foot western extension area. Workman operates three large hydraulic excavators, two Caterpillar Inc. (Cat®) 993 loaders and nine D11 track bulldozers. Two additional D11 track dozers will be added from Pax to achieve its surface production goals of 39 million bcy per year. Two highwall miners provide additional production tonnage when the final highwalls are exposed. Production from the highwall miners is expected to be sporadic due to highwall exposure of the surface mine and presence of deep-mine works. Alpha Metallurgical Resources, Inc. Statement of Coal Resources and Reserves for the Mid-West Virginia Surface Business Unit in Accordance with United States SEC Standards as of December 31, 2021 Central Appalachian Coal Basin West Virginia, USA MARSHALL MILLER & ASSOCIATES, INC. 50 The mine is expected to employ 191 operators in the surface mining phase of the operation and 20 operators in the highwall mining phase. Workman’s CHF employ an additional 7 employees to operate this facility. When they highwall miner is idled, its operators are expected to perform other supplemental tasks such as reclamation. At the above production level exhaustion of the reserves is expected to be in year 2035. 13.4.2.2 Kingston Surface (Map K2-K11) Figure 13-2: Kingston Surface Mine Permit Areas Aerial View The Kingston surface reserve area consists of mountain-top, contour and highwall mining of 30+ seams: from the Stockton to the Eagle - a difference of over 1,000 vertical feet. Deep mining has taken place in the Lower Cedar Grove, Upper and Lower No. 2 Gas, Powellton and Powellton lower split, Upper Eagle, and Eagle upper and lower splits. Previous contour and augering mining have also been documented. The present mine plan consists of three permits: Kingston Surface, Paint Mountain, and White Oak. The White Oak permit (S-3008-21) is currently pending.
Alpha Metallurgical Resources, Inc. Statement of Coal Resources and Reserves for the Mid-West Virginia Surface Business Unit in Accordance with United States SEC Standards as of December 31, 2021 Central Appalachian Coal Basin West Virginia, USA MARSHALL MILLER & ASSOCIATES, INC. 51 MM&A did not attempt to confirm burden storage capacity as presented in Kingston’s permits. The Kingston surface operation has not reached the level of maturity of the Workman operation. Fewer working areas have been established with present disturbance being limited to the Kingston Surface permit. Mining activity is expected to be similar to Workman: hydraulic shovels / front-end loaders mining lower seam contours. Dozers will help mine intermediate seams in help reclaim the lower seams. However due to strip ratio constraints, contour mining instead of mountain-top excavation is expected to complete excavation of the upper seams. Less push volume availability is expected to require more haulage contribution to reclaiming highwalls. Hollow fills of substantial storage volume are primarily limited to the Kingston and Paint Mountain permits. Excess spoil capacity needs for the White Oak permit will be primarily provided by the backfilling of the other two permits. The reserves of the White Oak permit will be the last to be exhausted. Kingston operates one large hydraulic excavator, one 993 loader and two D11 track bulldozers. As excavation provides room for more active areas, equipment from exhausted thermal coal operations is expected to be added to Kingston’s fleet. An additional large excavator, two additional 993 loaders, and four additional track bulldozers will double the overburden production to about 19 million bcy per year within five years. One highwall miner will provide additional production tonnage as highwalls are exposed. The mine employs 87 operators presently in the surface mining phase of the operation and 10 operators in the highwall mining phase. After five years the number of operators is expected to increase to 154 for the surface mining phase and 20 operators for highwall mining phase. At the above production level exhaustion of the reserves is expected to be in year 2042. 14 Processing and Recovery Methods 14.1 Description or Flowsheet The Alpha MWVS Operations includes the Kingston Preparation Plant. Washed coal product is transported from the preparation plant by truck haulage to the Pax loadout with access to the CSX Railroad. The Pax loadout was constructed in 2006 and can load railroad car at a rate of 3,500 tons per hour. Coal can also be transported by truck to Alpha’s Marmet dock barge loading facilities. The docks are located on the Kanawha River near Marmet, West Virginia and provider barge transportation to the customer. Barges can be loaded at the rate of 1,600 tons per hour and the facility was built in 1986. Coal Production is also conveyed from Workman Creek, through underground mine works to the Marfork Preparation Plant for processing and shipment on the CSX railroad system. Coal can also be Alpha Metallurgical Resources, Inc. Statement of Coal Resources and Reserves for the Mid-West Virginia Surface Business Unit in Accordance with United States SEC Standards as of December 31, 2021 Central Appalachian Coal Basin West Virginia, USA MARSHALL MILLER & ASSOCIATES, INC. 52 trucked to MWVUG Mammoth Preparation plant for processing. The Mammoth Plant provides rail loading on the Kanawha River Railroad shortline that connects to the Norfolk Southern and CSX Transportation railroad systems as well as on-site barge loading on the Kanawha River. Each of the plant sites include raw coal storage, clean coal storage and refuse disposal areas. The Kingston preparation plant was constructed in 1974 and has a raw feed rate capacity of 700 raw tons per hour. Primary separation equipment includes Peters heavy media vessels, Krebs heavy media cyclones, Multitech spirals, and Denver froth cells, supported by the requisite screens, centrifuges, sumps, pumps, and distribution systems. Coarse and fine refuse are disposed in an adjacent slurry cell impoundment. During the 2021 reporting year, the Kingston plant produced a product with a typical ash content of 7.90%, and a typical sulfur content 0.66% at a utilization rate of 58.12%. Product transportation from the preparation plant is by highway truck to either the Pax Railroad Loadout or to barge loading facilities along the Kanawha River near Marmet, West Virginia. An aerial image of the Kingston Preparation Plant and refuse area is shown in Figure 14-1. Figure 14-1: MWVS Kingston Preparation Plant and Refuse Area

As mining is common in the surrounding areas, the workforce is generally familiar with mining practices, and many are experienced miners. Water is sourced locally from public water sources or rivers, and electricity is sourced from Appalachian Electric Power (AEP). The service industry in the areas surrounding the mine operations has historically provided supplies, equipment repairs and fabrication, etc. 15 Infrastructure The Kingston Preparation Plant services the area with washed coal, which is transported via highway trucks to the Pax Loadout located on WATCO’s Kanawha River Railroad shortline railroad or to barge loading facilities along the Kanawha River near Marmet, West Virginia. Haul roads, primary roads, and Alpha Metallurgical Resources, Inc.

This practice will continue for future reserves. As an active operation, the necessary support infrastructure for MWVS is in place. As new areas are developed, the infrastructure requirements will change. These changes have been considered in the LOM plans and financial model. The underground mining resource areas which are located below drainage will require surface facilities, mine access slope development to the coal seam and ventilation facilities. Typical surface facilities include a mine office, a change house, supply facilities, mine fan and a stacker conveyor for run of mine coal storage.

The pricing data assumes a flat-line long term realization average of $144 per short ton port loading, with an average of $102.26 netback pricing reflective of the mid-volatile product, $144 per short ton port loading with an average of $111.29 per short ton netback pricing reflective of the low-volatile product, and $138 per short ton port loading, with an average of $108.08 netback pricing reflective of the high-volatile product currently sold at MWVS. A portion of the surface mine production is also thermal product which assumes a flat-line long term realization of $76 per short ton with an average of $66.68 per ton netback pricing. The LOM blended average netback pricing for the MWVS reserves is $95.97 per ton. These estimates are based on long term pricing published by third party sources and adjusted for quality and transportation. A large majority of the coal sold by Alpha and their MWVS business group is shipped internationally as part of blended products from other business units within Alpha or sourced from other companies. These netback adjustments reflect these additional costs carried after the products leave the MWVS business unit.

For MWVS, since all mining, preparation and marketing is done in-house, the remaining contracts required are: > Transportation – Alpha contracts with the Norfolk Southern Railroad and CSX Transportation to transport coal to market. Barge transportation on the Kanawha River is contracted through various parties. > Sales – Sales contracts are a mix of spot and contract sales. With the volatility of the market, long- term contracts are not typically written. Alpha Metallurgical Resources, Inc.

The environmental review completed by MM&A included site inspections, reviews of historical records, database searches of State and Federal regulatory records and interviews to identify potential recognized environmental conditions (RECs) that may create environmental liability for the sites. While MM&A identified RECs during both studies, MM&A’s opinion was that those issues would not preclude the continued or future use of the properties as a coal mining/preparation venture. Based on this former ESA completed by MM&A, it is MM&A’s opinion that MWV Surface has a generally typical coal industry record of compliance with applicable mining, water quality, and environmental laws. Estimated costs for mine closure, including water quality monitoring during site reclamation, are included in the financial models. 17.2 Requirements and Plans for Waste Disposal Based on a recent engineering review, done by Alpha, the Kingston Preparation Plant has approximately 14 years of fine refuse disposal capacity and 14 years of coarse refuse disposal capacity at projected rates have been identified for the Kingston refuse area, 3 years of which is permitted and active. In addition, some of the MWVS reserves are processed through the Marfork Preparation Plant. Those remaining capacities are also provided in Table 17-1. Securing additional coarse and fines capacity will be critical to execute the business plan as outlined in this TRS. The refused expansion has MSHA approval and awaiting Article III, DEP approval. The table below outlines the current estimated capacities and permits of MWVS Kingston’s fine and coarse impoundments.

Permits generally require that the permittee post a performance bond in an amount established by the regulatory program to provide assurance that any disturbance or liability created during mining operations is properly restored to an approved post-mining land use and that all regulations and requirements of the permits are fully satisfied before the bond is returned to the permittee. Significant penalties exist for any permittee who fails to meet the obligations of the permits including cessation of mining operations, which can lead to potential forfeiture of the bond. Any company, and its directors, owners and officers, which are subject to bond forfeiture can be denied future permits under the program.1 New permits or permit revisions will occasionally be necessary to facilitate the expansion or addition of new mining areas on the Property, such as amendments to existing permits and new permits for mining of reserve areas. Exploration permits also are required. Property under lease includes provisions for exploration among the terms of the lease. New or modified mining permits are subject to a public advertisement process and comment period, and the public is provided an opportunity to raise objections to any proposed mining operation. MM&A is not aware of any specific prohibition of mining on the subject property and given sufficient time and planning, Alpha should be able to secure new permits to maintain its planned mining operations within the context of current regulations. Necessary permits are in place to support current production on the Property, but future permits are required to maintain and expand production. Portions of the Property are located near local communities. Regulations prohibit mining activities within 300 feet of a residential dwelling, school, 1 Monitored under the Applicant Violator System (AVS) by the Federal Office of Surface Mining.

Where required, Alpha reports that such consents have been obtained where mining is proposed beyond the regulatory limits. Alpha has obtained all mining and discharge permits to operate its mines and processing, loadout or related facilities. MM&A is unaware of any obvious or current Alpha permitting issues that are expected to prevent the issuance of future permits. MWVS, along with all coal producers, is subject to a level of uncertainty regarding future clean water permits due to United States Environmental Protection Agency (EPA) involvement with state programs. The Mining permits currently held by Alpha MWVS are shown in Table 17-2.

In general, site reclamation includes removal of structures, backfilling, regrading, and revegetation of disturbed areas. For surface mines, the majority of the expense for backfilling and regrading is completed as part of ongoing mining operations, with only reclamation of final pits and HWM benches required at end-of-mine life. Sediment control is required during the establishment of vegetation, and bond release generally requires a minimum five-year period of site maintenance, water sampling, and sediment control following mine completion. This requirement is reduced to two years for certain operations involving re-mining. Reclamation of underground mines includes closure and sealing of mine openings such as portals and shafts in addition to the items listed above. Estimated costs for mine closure, including water quality monitoring during site reclamation, are included in the financial models. As with all mining companies, an accretion calculation is performed annually so the necessary Asset Retirement Obligations (ARO) can be shown as a Liability on the Balance Sheet. 17.6 Qualified Person’s Opinion The MWVS Business Unit is an operating facility; all necessary permits for current production have been obtained. MM&A knows of no reason that any permits revisions that may be required cannot be obtained. Estimated expenditures for site closure and reclamation are included in the financial model for this site. 18 Capital and Operating Costs 18.1 Capital Cost Estimate The production sequence selected for a property must consider the proximity of each reserve area to coal preparation plants, river docks and/or railroad loading points, along with suitability of production equipment to coal seam conditions. The in-place infrastructure was evaluated, and any future needs were planned to a level suitable for a Preliminary Feasibility Study and included in the Capital Forecast.
Alpha Metallurgical Resources, Inc. Statement of Coal Resources and Reserves for the Mid-West Virginia Surface Business Unit in Accordance with United States SEC Standards as of December 31, 2021 Central Appalachian Coal Basin West Virginia, USA MARSHALL MILLER & ASSOCIATES, INC. 63 Alpha provided MM&A with information related to the number of currently operating production units at MWVS. MM&A’s capital schedules assume that major equipment rebuilds occur over the course of each machine’s remaining assumed operating life. Replacement equipment was scheduled based on MM&A’s experience and knowledge of mining equipment and industry standards with respect to the useful life of such equipment. As one mine is depleted, the equipment is moved to its replacement. The capital expenditures tables detail costs for major equipment and infrastructure such as conveyor belt terminal groups. “Other” costs include expenditures for mine access and construction, mine extension capital and miscellaneous costs.

MM&A used the historical and/or budget cost information as a reference and developed a personnel schedule for the mine. Hourly labor rates and salaries were based upon information contained in Alpha’s financial summaries. Fringe benefit costs were developed for vacation and holidays, federal and state unemployment insurance, retirement, workers’ compensation and pneumoconiosis, casualty and life insurance, healthcare and bonuses. A cost factor for mine supplies was developed that relates expenditures to mine advance rates for roof control costs and other mine supply costs based on the historical cost data provided by Alpha. Other factors were developed for maintenance and repair costs, rentals, mine power, outside services, drilling & blasting, coal preparation plant processing, refuse handling, coal loading, property taxes, and insurance and bonding and other direct mining costs.

The results of this financial model are not intended to represent a bankable feasibility study, required for financing of any current or future mining operations contemplated for the Alpha properties, but are intended to establish the economic viability of the estimated coal reserves. Cash flows are simulated on an annual basis based on projected production from the coal reserves. The discounted cash flow analysis presented herein is based on an effective date of January 1, 2021. On an un-levered basis, the NPV of the project cash flow after taxes represents the Enterprise Value of the project. The project cash flow, excluding debt service, is calculated by subtracting direct and indirect operating expenses and capital expenditures from revenue. Direct costs include labor, operating supplies, maintenance and repairs, facilities costs for materials handling, coal preparation, refuse disposal, coal loading, reclamation and general and administrative costs. Indirect costs include statutory and legally agreed upon fees related to direct extraction of the mineral. The indirect costs are the Federal black lung tax, Federal and State reclamation taxes, property taxes, coal production royalties, and income taxes. The Alpha mines’ historical costs provided a useful reference for MM&A’s cost estimates. The operations are projected on a calendar year basis. MM&A’s projection of annual sales tonnage is summarized in the chart below. While all Alpha coal resources properties deemed by MM&A to have potential for classification as coal reserves were evaluated as part of the economic model, some of those resource areas were determined to be uneconomical in the current market and were therefore excluded from coal reserves as discussed below.
Alpha Metallurgical Resources, Inc. Statement of Coal Resources and Reserves for the Mid-West Virginia Surface Business Unit in Accordance with United States SEC Standards as of December 31, 2021 Central Appalachian Coal Basin West Virginia, USA MARSHALL MILLER & ASSOCIATES, INC. 67 Figure 19-1: Projection of Sales Tons Sales revenue is based on the metallurgical coal price information provided to MM&A by Alpha. Only the revenue from Alpha’s captive mining operations is included in the financial model used for this TRS. The P&L projections of the individual mines of Alpha’s MWVS operations are then consolidated into a P&L and cash flow schedule for further testing of the economics. Projected debt service is excluded from the P&L and cash flow model in order to determine Enterprise Value of the aggregated entity. The financial model expresses coal sales prices, operating costs, and capital expenditures in current day dollars without adjustment for inflation. Capital expenditures and reclamation costs are included based on engineering estimates for each mine by year. MM&A also included an estimate of administrative costs in the financial projections. Alpha will pay royalties for the various current and projected operations. The royalty rates vary by location as provided by Alpha. The royalty rates were assumed to be 5.0% to 8.25% of the sales revenue. The projection model also includes consolidated income tax calculations at Alpha’s MWVS Division level, incorporating statutory depletion calculations, as well as state income taxes, and a federal tax rate of 21%. To the extent the Alpha mines generate net operating losses for tax purposes, the losses Alpha Metallurgical Resources, Inc. Statement of Coal Resources and Reserves for the Mid-West Virginia Surface Business Unit in Accordance with United States SEC Standards as of December 31, 2021 Central Appalachian Coal Basin West Virginia, USA MARSHALL MILLER & ASSOCIATES, INC. 68 are carried over to offset future taxable income from Alpha mines. The terms “cash flows” and “project cash flows” used in this report refer to after-tax cash flows.

In addition, the financial model includes 5.8 Mt clean tons of resources. Consolidated cash flows are driven by annual sales tonnage, which grows from 3.3 million tons in 2022 to a peak of 5.3 million tons in 2032. Between years 2033 and 2035, sales ranges from 3.4 million to Alpha Metallurgical Resources, Inc. Statement of Coal Resources and Reserves for the Mid-West Virginia Surface Business Unit in Accordance with United States SEC Standards as of December 31, 2021 Central Appalachian Coal Basin West Virginia, USA MARSHALL MILLER & ASSOCIATES, INC. 72 4.5 million tons and between years 2036-2042, sales range from 0.8 million tons to 1.3 million tons. Projected consolidated revenue grows from $77 million in 2022 to a peak of $517 million in 2032. Revenue totals $6.5 billion for the project’s life. Consolidated cash flow from operations is positive throughout the projected operating period, with the exception of post-production years, due to end-of-mine reclamation spending. Consolidated cash flow from operations peaks at $146.9 million in 2032 and totals $1.6 billion over the project life. Capital expenditures total $177.8 million during the first five years and $312.2 million over the project’s life. Consolidated MWVS net cash flow after tax, but before debt service, is shown by year in the chart below: Figure 19-5: Net Cash Flow after Tax (Before Debt Service) LOM Net cash flow is positive for this project. The cash flows after year 2042 are generally related to end of mine reclamation expenditures, which are accrued over the life of the mines. 19.1.3 Discounted Cash Flow Analysis Cash flow after tax, but before debt service, generated over the life of the project was discounted to NPV at a 14.67% discount rate, which represents MM&A’s estimate of the constant dollar, risk adjusted WACC for likely market participants if the subject reserves were offered for sale.

Alpha Metallurgical Resources, Inc. Statement of Coal Resources and Reserves for the Mid-West Virginia Surface Business Unit in Accordance with United States SEC Standards as of December 31, 2021 Central Appalachian Coal Basin West Virginia, USA MARSHALL MILLER & ASSOCIATES, INC. 73 basis, the NPV of the project cash flows represents the Enterprise Value of the project and amounts to $447.2 million. Alpha is an active producer, and the financial model shows positive net cash flow for each year of the operating life of the MWVS reserves. The pre-feasibility financial model prepared for the TRS was developed to test the economic viability of each coal resource area. The NPV estimate was made for purposes of confirming the economics for classification of coal reserves and not for purposes of valuing Alpha or its MWVS assets. Mine plans were not optimized, and actual results of the operations may be different, but in all cases, the mine production plan assumes the properties are under competent management. 19.1.4 Sensitivity Analysis Sensitivity of the NPV results to changes in the key drivers is presented in the chart below. The sensitivity study shows the NPV at the 14.67% discount rate when Base Case sales prices, operating costs, capital costs and discount rate are increased and decreased in increments of 5% within a +/- 15% range. Figure 19-6: Sensitivity of NPV As shown, NPV is quite sensitive to change in sales price and operating cost estimates, and slightly sensitive to changes in capital cost estimates.

MM&A utilized this former audit study as the basis of an updated study which meets those standards set forth by the SEC for 2021 reserve compliance. 22 Interpretation and Conclusions 22.1 Conclusion Sufficient data has been obtained through various exploration and sampling programs and mining operations to support the geological interpretations of seam structure and thickness for coal horizons situated on the MWVS Property. The data is of sufficient quantity and reliability to reasonably support the coal resource and coal reserve estimates in this TRS. The geological data and preliminary feasibility study, which consider mining plans, revenue, and operating and capital cost estimates are sufficient to support the classification of coal reserves provided herein. This geologic evaluation conducted in conjunction with the preliminary feasibility study is sufficient to conclude that the 60.7 Mt of marketable coal reserves identified on the Property are economically mineable under reasonable expectations of market prices for metallurgical coal products, estimated operation costs, and capital expenditures. 22.2 Risk Factors Risks have been identified for operational, technical and administrative subjects addressed in the Pre- Feasibility Study. A risk matrix has been constructed to present the risk levels for all the risk factors identified and quantified in the risk assessment process. The risk matrix and risk assessment process are modelled to that presented in the Australian and New Zealand Standard on Risk Management (AS/NZS 4360).
Alpha Metallurgical Resources, Inc. Statement of Coal Resources and Reserves for the Mid-West Virginia Surface Business Unit in Accordance with United States SEC Standards as of December 31, 2021 Central Appalachian Coal Basin West Virginia, USA MARSHALL MILLER & ASSOCIATES, INC. 75 The purpose of the characterization of the project risk components is to inform the project stakeholders of key aspects of the Alpha projects that can be impacted by events whose consequences can affect the success of the venture. The significance of an impacted aspect of the operation is directly related to both the probability of occurrence and the severity of the consequences. The initial risk for a risk factor is herein defined as the risk level after the potential impact of the risk factor is addressed by competent and prudent management utilizing control measures readily available. Residual risk for a risk factor is herein defined as the risk level following application of special mitigation measures if management determines that the initial risk level is unacceptable. Initial risk and residual risk can be quantified numerically, derived by the product of values assigned to probability and consequence ranging from very low risk to very high risk. The probability and consequence parameters are subjective numerical estimates made by practiced mine engineers and managers. Both are assigned values from 1 to 5 for which the value 1 represents the lowest probability and least consequence, and the value 5 represents the highest probability and greatest consequence. The products, which define the Risk Level, are classified from very low to very high. Risk Level Table (R = P x C) Risk Level (R) Very Low (1 to 2) Low (3 to 5) Moderate (6 to 11) High (12 to 19) Very High (20 to 25) Risk aspects identified and evaluated during this assignment total 15. No residual risks are rated Very High. Three (3) residual risks are rated High. Six (6) of the risk aspects could be associated with Moderate residual risk. Four (4) of the risk aspects were attributed Low or Very Low residual risks. 22.2.1 Governing Assumptions The listing of the aspects is not presumed to be exhaustive. Instead that listing is presented based on the experiences of the contributors to the TRS. 1. The probability and consequence ratings are subjectively assigned, and it is assumed that this subjectivity reasonably reflects the condition of the active and projected mine operations. 2. The Control Measures shown in the matrices presented in this chapter are not exhaustive. They represent a condensed collection of activities that the author of the risk assessment section has observed to be effective in coal mining scenarios. Alpha Metallurgical Resources, Inc. Statement of Coal Resources and Reserves for the Mid-West Virginia Surface Business Unit in Accordance with United States SEC Standards as of December 31, 2021 Central Appalachian Coal Basin West Virginia, USA MARSHALL MILLER & ASSOCIATES, INC. 76 3. Mitigation Measures listed for each risk factor of the operation are not exhaustive. The measures listed, however, have been observed by the author to be effective. 4. The monetary values used in ranking the consequences are generally-accepted quantities for the coal mining industry. 22.2.2 Limitations The risk assessment proposed in this report is subject to the limitations of the information currently collected, tested, and interpreted at the time of the writing of the report. 22.2.3 Methodology The numerical quantities (i.e., risk levels) attributable to either “initial” or “residual” risks are derived by the product of values assigned to probability and consequence ranging from very low risk to very high risk. R = P x C Where: R = Risk Level P = Probability of Occurrence C = Consequence of Occurrence The Probability (P) and Consequence (C) parameters recited in the formula are subjective numerical estimates made by practiced mine engineers and managers. Both P and C are assigned integer values ranging from 1 to 5 for which the value 1 represents the lowest probability and least consequence, and the value 5 represents the highest probability and greatest consequence. The products (R = P x C) which define the Risk Level, are thereafter classified from very low to very high. Risk Level Table Risk Level (R) Very Low (1 to 2) Low (3 to 5) Moderate (6 to 11) High (12 to 19) Very High (20 to 25) Very high initial risks are considered to be unacceptable and require corrective action well in advance of project development. In short, measures must be applied to reduce very high initial risks to a tolerable level. As shown and discussed above, after taking into account the operational, technical, and administrative actions that have been applied or are available for action when required, the residual risk can be determined. The residual risk provides a basis for the management team to determine if the residual

Statement of Coal Resources and Reserves for the Mid-West Virginia Surface Business Unit in Accordance with United States SEC Standards as of December 31, 2021 Central Appalachian Coal Basin West Virginia, USA MARSHALL MILLER & ASSOCIATES, INC. 77 risk level is acceptable or tolerable. If the risk level is determined to be unacceptable, further actions should be considered to reduce the residual risk to acceptable or tolerable levels to provide justification for continuation of the proposed operation. 22.2.4 Development of the Risk Matrix Risks have been identified for the technical, operational, and administrative subjects addressed in the TRS. The risk matrix and risk assessment process are modelled to that presented in the Australian and New Zealand Standard on Risk Management (AS/NZS 4360). 22.2.4.1 Probability Level Table Table 22-1: Probability Level Table Category Probability Level (P) 1 Remote Not likely to occur except in exceptional circumstances. <10% 2 Unlikely Not likely to occur; small in degree. 10 - 30% 3 Possible Capable of occurring. 30 - 60% 4 Likely High chance of occurring in most circumstances. 60 - 90% 5 Almost Certain Event is expected under most circumstances; impossible to avoid. >90% The lowest rated probability of occurrence is assigned the value of 1 and described as remote, with a likelihood of occurrence of less than 10 percent. Increasing values are assigned to each higher probability of occurrence, culminating with the value of 5 assigned to incidents considered to be almost certain to occur. 22.2.4.2 Consequence Level Table Table 22-2 lists the consequence levels.

Risk reduction measures must be applied to reduce very high risks to a tolerable level. 22.2.6 Description of the Coal Property The MWVS Business Unit is located in located in Raleigh , and Fayette Counties, West Virginia – is an active operation with one underground mine and four surface mines. The active underground operation within the MWVS Business Unit (Kingston 2 Mine) utilizes two continuous mining production sections. The method provides continuity, preserving skilled work groups and enabling effective Alpha Metallurgical Resources, Inc. Statement of Coal Resources and Reserves for the Mid-West Virginia Surface Business Unit in Accordance with United States SEC Standards as of December 31, 2021 Central Appalachian Coal Basin West Virginia, USA MARSHALL MILLER & ASSOCIATES, INC. 80 utilization of production equipment. The active surface mining operations include the Workman Creek and Kingston Mines. The surface mines employ contour, area and highwall mining methods. 22.2.7 Summary of Residual Risk Ratings Each risk factor is numbered, and a risk level for each is determined by multiplying the assigned probability by the assigned consequence. The risk levels are plotted on a risk matrix to provide a composite view of the Alpha risk profile. The average risk level is 7.2, which is defined as Moderate. Table 22-4: Risk Assessment Matrix C o n se q u en ce Critical >$50 MM Major $10-50MM 9 6,15 Moderate $2-10 MM 1, 12 4, 8, 14 2, 3 Minor $0.5-$2 MM 13 5, 7, 10 Low <$0.5 MM 11 <10% 10-30% 30-60% 60-90% >90% Remote Unlikely Possible Likely Almost Certain 22.2.8 Risk Factors A high-level approach is utilized to characterize risk factors that are generally similar across a number of the active and proposed mining operations. Risk factors that are unique to a specific operation or are particularly noteworthy are addressed individually. 22.2.8.1 Geological and Coal Resource Coal mining is accompanied by risk that, despite exploration efforts, mining areas will be encountered where geological conditions render extraction of the resource to be uneconomic, or that coal quality characteristics disqualify the product for sale into target markets. Offsetting the geological and coal resource risk are the size of the controlled property which allows flexibility in the selection of mine areas away from areas where coal quality and mineability are less favorable. In addition, many of the underground mines are designed to operate with multiple production sections each, which lessens the immediate impact when one section encounters difficulties. The large reserve areas also provide a mitigation strategy of varying the timing of
Alpha Metallurgical Resources, Inc. Statement of Coal Resources and Reserves for the Mid-West Virginia Surface Business Unit in Accordance with United States SEC Standards as of December 31, 2021 Central Appalachian Coal Basin West Virginia, USA MARSHALL MILLER & ASSOCIATES, INC. 81 development of mines to offset expected or encountered adverse conditions, thereby maintaining consistent production and quality. This flexibility requires additional extension or development cost but increases performance consistency. The larger reserve areas will be developed with multiple production sections and the small, replacement production reserve areas provide ready access to alternative locations if geological and coal resource characteristics require abandonment of an active production area. Table 22-5: Geological and Coal Resource Risk Assessment (Risks 1 and 2) Aspect Impact Control Measures Initial Risk Level Mitigation Measures Residual Risk Level P C R P C R Recoverable coal tons recognized to be significantly less than previously estimated. Reserve base is adequate to serve market commitments and respond to opportunities for many years. Local adverse conditions may increase frequency and cost of production unit relocations. Previous and ongoing exploration and extensive regional mining history provide a high level of confidence of coal seam correlation, continuity of the coal seams, and coal resource tons. 1 4 4 Optimize mine plan to increase resource recovery; develop mine plan to provide readily available alternate mining locations to sustain expected production level. 1 3 3 Coal quality locally proves to be lower than initially projected. If uncontrolled, production and sale of coal that is out of specification can result in rejection of deliveries, cancellation of coal sales agreements and damage to reputation. Clean coal quality related to surface mines is largely justified by historical trends as opposed to exploration data. Exploration and vast experience and history in local coal seams provide confidence in coal quality; limited excursions can be managed with careful product segregation and blending. 3 5 15 Develop mine plan to provide readily available alternate mining locations to sustain expected production level; modify coal sales agreements to reflect coal quality. 3 3 9 22.2.8.2 Environmental Water quality and other permit requirements are subject to modification and such changes could have a material impact on the capability of the operator to meet modified standards or to receive new permits and modifications to existing permits. Permit protests may result in delays or denials to permit applications. Environmental standards and permit requirements have evolved significantly over the past 50 years and to-date, mining operators and regulatory bodies have been able to adapt successfully to evolving environmental requirements. Alpha Metallurgical Resources, Inc.

Cost control measures implemented; capital spending deferred. 4 5 20 High-cost operations closed, and employees temporarily furloughed. 4 4 16 Occasional delay or interruption of rail, river and terminals service may be expected. The operator can possibly minimize the impact of delays by being a preferred customer by fulfilling shipment obligations promptly and maintaining close working relationships. Table 22-9: Market and Transportation (Risk 7) Aspect Impact Control Measures Initial Risk Level Mitigation Measures Residual Risk Level P C R P C R Rail or river transport is delayed; storage and shipping access at river and ocean terminals is not available. Fulfillment of coal sales agreements delayed; limited coal storage at mines may increase cost of rehandling; production may be temporarily idled. Provide adequate storage capacity at mines; coordinate continuously with railroad and shipping companies to respond quickly and effectively to changing circumstances. 4 3 12 Provide back-up storage facility along with personnel, equipment and rehandle plan to sustain production and fulfill sales obligations timely. 4 2 8 22.2.8.5 Mining Plan Occupational health and safety risks are inherent in mining operations. Comprehensive training and retraining programs, internal safety audits and examinations, regular mine inspections, safety meetings, along with support of trained fire brigades and mine rescue teams are among activities that greatly reduce accident risks. Employee health monitoring programs coupled with dust and noise monitoring and abatement reduce health risks to miners. As underground mines are developed and extended, observation of geological, hydrogeological and geotechnical conditions lead to modification of mine plans and procedures to enable safe work within the mine environments. Highlighted below are selected examples of safety and external factors relevant to Alpha’s operations. 22.2.8.5.1 Methane Management Coalbed methane is potentially present in coal operations however, the methane concentration in shallow coal seams is at such low levels that it can be readily managed with frequent testing and Alpha Metallurgical Resources, Inc. Statement of Coal Resources and Reserves for the Mid-West Virginia Surface Business Unit in Accordance with United States SEC Standards as of December 31, 2021 Central Appalachian Coal Basin West Virginia, USA MARSHALL MILLER & ASSOCIATES, INC. 84 monitoring, vigilance, and routine mine ventilation. Methane is not expected to be present in most of the MWVS property. Table 22-10: Methane Management (Risk 8) Aspect Impact Control Measures Initial Risk Level Mitigation Measures Residual Risk Level P C R P C R Methane hazard is present in mines operating below drainage. Injury or loss of life; possible ignition of gas and mine explosion; potential loss of mine and equipment temporarily or permanently; additional mine fan, mine power, ventilation, monitoring and examination requirements. Low to moderate levels can be managed with frequent examinations, testing and monitoring within the mine ventilation system. Excellent rock dust maintenance minimizes explosion propagation risk should an ignition occur. 2 5 10 Very high-level methane concentrations may require coal seam degasification and gob degasification where pillar extraction methods are employed. 2 3 6 22.2.8.5.2 Mine Fires Mine fires, once common at mine operations, are rare today. Most active coal miners have not encountered a mine fire. Vastly improved mine power and equipment electrical systems, along with safe mine practices reduce mine fire risks. Crew training and fire brigade support and training improve response for containment and control if a fire occurs. Spontaneous combustion within coal mines, which is the source of most fires that occur today, is not expected to commonly occur at the Alpha property. When spontaneous combustion conditions are present, monitoring systems are employed for early detection and mine plans are designed to facilitate isolation, containment and rapid extinguishment.

Ground control-based risks can be mitigated through effective roof control plans which are supplemented with a strong understanding of future geotechnical conditions. Foremen and crews should be trained to examine the roof, rib and floor conditions and identify pending and immediate hazards. Multiple publicly available software programs can be used to assess pillar sizing and stability.

Coal quality is based on a weighted average of laboratory data from core holes. The combination of surface and inherent moisture is modeled at 6.0-percent. Raw quality and some volatile matter analysis not available for Workman Creek . Workman Creek surface reserves were priced at 60% High-Vol. A and 40% thermal product. Douglas seam volatile matter analysis not available. Douglas seam priced as a Mid-Vol. product, consistent with Kingston 2 production. Actual product moisture is dependent upon multiple geological factors, operational factors, and product contract specifications and can exceed 8-percent. As such, the modeled moisture values provide a level of conservatism for reserve reporting. Totals may not add due to rounding. Workman Creek Surface is modeled as 55% direct-ship and 45% washed to mimic what Alpha is doing, however without any raw quality data for the surface seams a quality composite could not be prepared.
