Alpha Metallurgical Resources, Inc. Statement of Coal Resources and Reserves for the Marfork Mining Complex in Accordance with United States SEC Standards as of December 31, 2022 Central Appalachian Coal Basin West Virginia, USA MARSHAL MILLER & ASSOCIATES, INC. 7 1 Executive Summary 1.1 Property Description Alpha Metallurgical Resources, Inc. (Alpha) authorized Marshall Miller & Associates, Inc. (MM&A) to prepare this updated Technical Report Summary (TRS) of its controlled coal reserves located at the Marfork Mining Complex (Marfork or the Property) in Raleigh, Boone, Fayette and Kanawha Counties, West Virginia. Coal resources and coal reserves are herein reported in imperial units of measurement. The Marfork Mining Complex is comprised of the Marfork underground operations and the Workman Creek surface mines. Active surface facilities for the Marfork operations are located along Little Marsh Fork, a tributary of the Big Coal River adjacent to a CSX rail line. Active surface facilities for Workman Creek are located in Raleigh County, West Virginia, located along Workman Creek, a tributary to Clear Fork along State Route 1. Both surface facilities are about 30 miles northwest of Beckley, West Virginia, the county seat of Raleigh County (see Figure 1-1). Marfork properties are included within Alpha’s Mid-West Virginia mineral holdings that are composed of approximately 253,750 total acres. There are approximately 55 separate leases for the Mid-West Virginia mineral holdings group, which includes Marfork resource area. Alpha Metallurgical Resources, Inc. Statement of Coal Resources and Reserves for the Marfork Mining Complex in Accordance with United States SEC Standards as of December 31, 2022 Central Appalachian Coal Basin West Virginia, USA MARSHAL MILLER & ASSOCIATES, INC. 8 Figure 1-1: Alpha’s Marfork Property Location Map 1.2 Ownership The Marfork Property involves a complex combination of previous ownership. Predecessors of Alpha, namely Alpha Natural Resources (Alpha) and Massey Energy (Massey) previously held mining rights on most of the Property. 1.3 Geology Operations at the Marfork Mining Complex currently extract coal from the Eagle and Glen Alum Tunnel coal seams by the underground continuous mining method. Currently identified underground coal resources and reserves are in the Chilton, Hernshaw, Upper Cedar Grove, Middle Cedar Grove, Lower Cedar Grove, Peerless, Powellton, Eagle, Glen Alum Tunnel, Beckley, and Fire Creek seams. Workman Creek surface mines recover coal from the Upper, Middle and Lower Clarion; Stockton, Upper Coalburg, Coalburg, Lower Coalburg, Upper Winifrede Rider, Upper Winifrede, Winifrede, Lower Winifrede,

These coal seams are historically utilized as coking coal. Strata on the Property reside in the Pennsylvanian-aged (approximately 290 to 330 million years ago) Kanawha and New River Formations. Due to the high value of these coking coals, all the seams have been extensively mined in the past. The rock formations between the coal seams are characterized by large proportions of sandstone interspersed with shale units. The coal seams reach the highest structural elevations along the southeastern margin of the Property, generally dipping toward the northwest. 1.4 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. A significant amount of historical 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 Marfork Mining Complex. The Alpha acquired exploration data has been consistent with past drilling activities. 1.5 Operations and Development As of December 31, 2022, the Marfork Mining Complex is comprised of surface and underground operations. Active surface mine operations at Workman Creek, including the Long Ridge, Center Contour, Collins Fork, and Middle Ridge permits. Underground mine operations were active at the Black Eagle Mine, Panther Eagle, and Horse Creek mines; all located in the Eagle coal seam and the Glen Alum mine operating in the Glen Alum Tunnel seam. The active Slabcamp mine in the Stockton coal seam is a part of Mammoth Complex and is not a part of this study. The Dow Fork mine is currently in the conceptual stage and is planned to operate in the Eagle seam. The active Eagle seam mines and the Dow Fork mine produce, or will produce, a High-Volatile metallurgical coal blend. The Glen Alum mine produces a Mid-Volatile product. Based on the mine plans developed as part of this TRS, annual deep mine production peaks at 2.73 million tons in 2053. Underground reserves will be depleted in 2064. Surface mine production peaks Alpha Metallurgical Resources, Inc. Statement of Coal Resources and Reserves for the Marfork Mining Complex in Accordance with United States SEC Standards as of December 31, 2022 Central Appalachian Coal Basin West Virginia, USA MARSHAL MILLER & ASSOCIATES, INC. 10 at 2.55 million tons in 2023 and surface reserves will be depleted in 2033. Highwall mine production peaks at 0.46 million tons in 2035 and those reserves are scheduled to be depleted in 2035. In addition to the mines, the Marfork Mining Complex also includes the Marfork Preparation Plant. The plant site includes raw coal storage, clean coal storage, a centrifugal dryer, a railroad loadout as well as two refuse disposal areas. Low-density cyclones are used for intermediate separation and froth flotation and spirals are utilized for fine coal separation. The plant has a feed rate capacity of 2,400 raw tons per hour and produces 6.98 % ash at less than 1.05 % sulfur.

Note (2): Coal resources are reported on a dry basis. Surface moisture and inherent moisture are excluded. Note (3): The Property contains 159.1 million tons (Mt) of dry, in-place measured and indicated coal resources exclusive of reserves (not converted to reserve) as of December 31, 2022. Totals may not add due to rounding. See Appendix A for detailed breakdown. 1.7 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, 2023. 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; geological encumbrances associated with overlying and underlying strata; seam thinning; structural complication; and insufficient exploration have all been considered. Reserve consideration excludes those portions of the resource area that exhibit geological and 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. Alpha Metallurgical Resources, Inc.

Coal quality is based on a weighted average of laboratory analysis from core holes. The combination of surface and inherent moisture is modeled at 6.0-percent. 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. Raw quality and some volatile matter analysis not available for Workman Creek. Workman Creek surface reserves were priced at 70% High-Vol. A and 30% thermal product. 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. Totals may not add due to rounding. In summary, Alpha controls a total of 106.2 million tons (Mt) (moist basis) of marketable coal reserves at Marfork. Of that total, 52 percent are proven, and 48 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. Approximately 2.2 Mt are owned, and the remaining 104.0 Mt are leased coal reserves. Of the total, 58.4 Mt are permitted, and the remaining 47.8 Mt are not permitted. The maps included in Appendix C reflect mining depletion at the time of the resource/reserve calculation taken from Alpha mine maps as of September 30, 2022. Mine depletion tonnages were supplied by Alpha through the end of 2022, and MM&A deducted this historical production from the mapped reserves to estimate reserves as of December 31, 2022. 1.8 Capital Summary Alpha provided MM&A with information related to the number of currently operating production units at the Marfork Mining Complex. 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.

A summary of the estimated capital for the consolidated Marfork operations is provided in Figure 1-2 below. Figure 1-2: Projected Capital Expenditures – Consolidated Marfork Mining Complex 1.9 Operating Costs Alpha provided historical operating costs for its active mines including:  Underground mine operations at Black Eagle, Panther Eagle, Horse Creek Eagle, and Glen Alum.  Surface and highwall mine operations at Workman Creek North and Workman Creek South. MM&A used the historical 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, Alpha Metallurgical Resources, Inc. Statement of Coal Resources and Reserves for the Marfork Mining Complex in Accordance with United States SEC Standards as of December 31, 2022 Central Appalachian Coal Basin West Virginia, USA MARSHAL MILLER & ASSOCIATES, INC. 14 rentals, mine power, outside services, coal preparation plant processing, refuse handling, coal loading, property taxes and insurance and bonding and other direct mining costs. 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. A summary of the projected operating costs for the consolidated Marfork operations is provided in Figure 1-3. Figure 1-3: Marfork Mining Complex Operating Costs 1.10 Economic Evaluation The pre-feasibility financial model prepared for this TRS was developed to test the economic viability of each coal resource area. 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, 2023.

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. Company-wide pricing data as provided by Alpha is described in Table 16-2. Note that not all products reflected in Table 16-2 will apply to every business unit. The pricing data assumes a flat-line long-term realization of $151 per short ton port pricing, with an average $118.75 per ton netback pricing reflective of the high-volatile product currently sold at Marfork, and $152 per short ton port loading with an average of $113.93 per short ton netback pricing reflective of the low-volatile product. A portion of the surface mine production is also thermal product which assumes a flat-line long term realization of $140 per short ton with an average of $133.75 per ton netback pricing. The LOM blended average netback pricing for the Marfork reserves is $118.55 per ton. These estimates are based on long-term pricing published by third party sources and adjusted for quality and transportation. The netback pricing represents adjustments made to published benchmark pricing based on quality and transportation. A large majority of the coal sold by Alpha and their Marfork Mining Complex is shipped internationally as part of blended products from other business units within Alpha or sourced from other companies. The netback adjustments reflect these additional costs carried after the products leave the Marfork Mining Complex. Table 1-3 shows the MM&A projected LOM tonnage, P&L, and EBITDA for each Alpha mine at Marfork. Alpha Metallurgical Resources, Inc.

Alpha Metallurgical Resources, Inc. Statement of Coal Resources and Reserves for the Marfork Mining Complex in Accordance with United States SEC Standards as of December 31, 2022 Central Appalachian Coal Basin West Virginia, USA MARSHAL MILLER & ASSOCIATES, INC. 18 Consolidated cash flows are driven by annual sales tonnage, which range from 3.8 million tons to 5.4 million tons between 2023 and 2033. Between years 2034 and 2062, sales ranges from 1.1 million to 2.7 million tons and between years 2063-2064, sales range from 0.03 million tons to 0.4 million tons. Projected consolidated revenue peaks at $652 million in 2023 and totals $13.3 billion for the project’s life. Consolidated cash flow from operations is positive throughout the projected operating period, apart from post-production years, due to end-of-mine reclamation spending. Consolidated cash flow from operations peaks at $178.9 million in 2024 and totals $3.6 billion over the project life. Capital expenditures total $185.8 million during the first five years and $1.2 billion over the project’s life. 1.10.1 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 15.04% 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 $777.2 million. Alpha is an active producer, and the financial model shows positive net cash flow for each year of the operating life of the Marfork 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 the purpose of confirming the economics for classification of coal reserves and not for purposes of valuing Alpha or its Marfork 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. 1.10.2 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 15.04% 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 Marfork Mining Complex in Accordance with United States SEC Standards as of December 31, 2022 Central Appalachian Coal Basin West Virginia, USA MARSHAL MILLER & ASSOCIATES, INC. 19 Figure 1-4: Sensitivity of NPV As shown, NPV is quite sensitive to changes in sales price, operating cost estimates and the discount rate, and slightly sensitive to changes in capital cost estimates. 1.11 Permitting Alpha has obtained all mining and discharge permits to operate its active mines, preparation plant processing, loadout, and 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) and United States Fish and Wildlife (USFW) involvement with state programs. 1.12 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 Marfork Property and reviewed in the study. 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 Marfork Mining Complex in Accordance with United States SEC Standards as of December 31, 2022 Central Appalachian Coal Basin West Virginia, USA MARSHAL MILLER & ASSOCIATES, INC. 20 This geologic evaluation conducted in conjunction with the preliminary feasibility study concludes that the 106.2 Mt of marketable underground 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 updated 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. 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. The report provides a statement of coal resources and coal reserves for Alpha, as defined under the United States Securities and Exchange Commission (SEC). 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.

Qualitied Persons involved in this TRS have conducted multiple site visits, most recently October 2022. 3 Property Description 3.1 Location The Marfork Mining Complex is in the Central Appalachian Basin of southern West Virginia (see Figure 1-1) with coal properties mostly in Raleigh and Boone counties. The underground mine properties are generally centered around the Marfork preparation plant and facilities located approximately 3 miles south of the town of Whitesville, West Virginia, and 30 miles northwest of Beckley, West Virginia, the county seat of Raleigh County. Surface facilities for the operation are in the Big Coal River drainage basin, central to the active mines as well as those currently in development. Surface facilities for the Workman Creek operation are located on Workman Creek, a tributary to Clear Fork along State Route 1. The Workman properties are east of and adjoining to the Marfork underground properties. Numerous small communities are present throughout the Property such as the previously mentioned town of Whitesville, as well as Sylvester, Montcoal and Clear Creek communities. The nearest major population centers are Charleston, West Virginia (40 miles north), Bristol, Virginia (170 miles south), Roanoke, Virginia (160 miles east), Morgantown, West Virginia (200 miles north), and Lexington, Kentucky (220 miles west). The Property is located on the following United States Geological Survey (USGS) Quadrangles: Williams Mnt., Sylvester, Eskdale, Wharton, Whitesville, Dorothy, Pax, Pilot Knob, Arnett, Eccles, and Beckley. The coordinate system and datum used for the model of the Marfork Mining Complex, and the subsequent maps were produced in the West Virginia State Plane South system, NAD 27. 3.2 Titles, Claims or Leases Marfork properties are included within Alpha’s Mid-West Virginia mineral holdings that are composed of approximately 253,750 acres located in Raleigh, Boone, Fayette and Kanawha Counties, West Virginia. There are approximately 55 separate leases for the Mid-West Virginia mineral holdings group which Kingston resource area is a part of. Some leases expire over the next several years, but Alpha does not anticipate any challenges related to lease renewal. Table 3-1 lists Alpha’s Mid-West Virginia mineral leases. 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

(3) Royalty rates range from 3% to 10% of gross selling price 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, through experience with the Property, MM&A has no knowledge of past property boundary disputes or other concerns that could impact 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.

Statement of Coal Resources and Reserves for the Marfork Mining Complex in Accordance with United States SEC Standards as of December 31, 2022 Central Appalachian Coal Basin West Virginia, USA MARSHAL MILLER & ASSOCIATES, INC. 25 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 land teams examine the deeds and title control to minimize this risk. Historically, property control has not posed any significant challenges related to Marfork’s operations. 4 Accessibility, Climate, Local Resources, Infrastructure and Physiography 4.1 Topography, Elevation, and Vegetation The topography of the area surrounding the Marfork Mining Complex is typical of the Central Appalachian Plateau’s physiographic province, being rugged and deeply dissected by V-shaped river valleys and flanked by steep-sided upland regions. Slopes in the area are mostly steep to very steep with some gently sloping with relatively narrow ridges. Surface elevations near the mine complex range from approximately 1,000 feet above sea level at streams to approximately 2,600 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 Marfork Property via a well-developed network of primary, secondary, and unimproved roads. 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 West Virginia State Route 1 and 3 that runs through the Property holdings and provides direct access to surface office facilities and preparation plant from points north and south. These primary roads typically stay open throughout the year. Within the Property, unimproved roads are utilized to access gas drainage wells and surface based deep mine infrastructure. The Alpha-owned office facilities, preparation plant and rail loadout are located approximately 3 miles south of the town of Whitesville along the CSX railroad system and serve as the primary transport means of processed coal. Alpha Metallurgical Resources, Inc. Statement of Coal Resources and Reserves for the Marfork Mining Complex in Accordance with United States SEC Standards as of December 31, 2022 Central Appalachian Coal Basin West Virginia, USA MARSHAL MILLER & ASSOCIATES, INC. 26 4.3 Proximity to Population Centers The Marfork Mining Complex is located near the town of Beckley and is primarily in Raleigh and Boone Counties, West Virginia. There are no large population centers in proximity. The nearest major population centers are Charleston, West Virginia (40 miles north), Bristol, Virginia (170 miles south), Roanoke, Virginia (190 miles southeast), and Morgantown, West Virginia (200 miles northeast), and Lexington, Kentucky (220 miles west). As of the 2020 census, Raleigh County had just over 74,600 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 May and end in early September and range in average temperature from 46 to 78 degrees Fahrenheit. 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 Marfork Mining Complex has sources of water, power, personnel, and supplies readily available for use. Personnel have historically been sourced from the surrounding communities in Raleigh, Kanawha, Fayette, and Boone Counties, and have proven to be adequate in numbers 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 complex has historically provided supplies, equipment repairs and fabrication, etc. Alpha’s Marfork preparation plant services consumers with washed coal, which is transported via the adjacent CSX rail line at the Marfork loadout. Haul roads, primary roads, and conveyor belt systems account for transport from the various mine sites to the preparation plant.

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. The current facilities were constructed in 1994 by Marfork Coal Company, a subsidiary of A. T. Massey Coal Company. The preparation plant, refuse disposal areas, utility infrastructure and rail transportation have been maintained and upgraded to provide a modern coal processing facility for 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 logging (e-logging). Coal-quality analyses were also employed during the core-exploration process. The development of this report included an assessment of over 1,000 exploration drill holes, largely comprised of coal measurements. 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. Drill hole locations used in this assessment are shown on the resource and reserve maps included in Appendix C. 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 US 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 Alpha Metallurgical Resources, Inc. Statement of Coal Resources and Reserves for the Marfork Mining Complex in Accordance with United States SEC Standards as of December 31, 2022 Central Appalachian Coal Basin West Virginia, USA MARSHAL MILLER & ASSOCIATES, INC. 28 Appalachian Basin. The Appalachian Basin is more than 250 miles wide and, in some portions, contains over 60 coal seams of varying economic significance. Coal seams and zones of economic significance typically range between 24 and 48 inches in thickness, with relatively little structural deformation. Regional structure is typically characterized by gently dipping strata to the northwest at one to four percent, averaging three percent. Strata on the Property are mostly of the Pennsylvanian-age Kanawha Formation and the older, lower Beckley and Fire Creek seams are 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, Little Eagle, Glen Alum Tunnel, Beckley and Fire Creek 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 Marfork Property.

The higher rank Glen Alum and Beckley coals will produce a Mid-Volatile and a Low-Volatile product. Due to the high value of these High Volatile coking coals, all the seams have been extensively mined in the past. Generally, the coal rank increases with depth whereas the highest seams stratigraphically and physically on the hills exhibit the greatest volatile matter content and deepest seams exhibit the lowest volatile matter content. The highest structural elevations are along the southeastern margin of the Property with the strata generally dipping toward northwest. The Marfork underground coal seams of interest above drainage include the Chilton through the Glen Alum Tunnel and are accessible via an outcrop faceup. Below-drainage seams of interest include the Beckley and the Fire Creek and would require slope development access. The rock formations between the coal seams are characterized by large portions of sandstone with shale units interspersed throughout.

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 logging (e- logging). 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 portion of the past exploration holes, including most of the recently drilled holes. Drill hole locations are 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 deep mineable coal horizons. Core logging is carried out by geologists in cases where roof and floor strata are of particular interest and in cases where greater resolution and geologic detail are needed. In many cases the drill hole data comes from simplified driller’s logs, which may lack specific 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, 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. A typical cross-section for Workman Creek and Marfork is shown in Figure 7-1 and Figure 7-2. Alpha Metallurgical Resources, Inc. Statement of Coal Resources and Reserves for the Marfork Mining Complex in Accordance with United States SEC Standards as of December 31, 2022 Central Appalachian Coal Basin West Virginia, USA MARSHAL MILLER & ASSOCIATES, INC. 32 Figure 7-1: Workman Creek Cross-Section

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 Alpha Metallurgical Resources, Inc. Statement of Coal Resources and Reserves for the Marfork Mining Complex in Accordance with United States SEC Standards as of December 31, 2022 Central Appalachian Coal Basin West Virginia, USA MARSHAL MILLER & ASSOCIATES, INC. 34 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 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 and 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 mine maps supplied by Alpha 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 and filling any gaps with digital USGS topographic mapping. 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 core holes, the geophysical logs are especially useful in verifying the 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. 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, more recent holes are generally supplemented by a more detailed core log completed by a geologist. These drilling logs were provided to MM&A as a geological database. MM&A geologists were not involved in the production of original core logs but did perform a basic check of information within the provided database. An audit of the Alpha database was conducted by comparing seam depths, coal, and parting thicknesses in the electronic database against the source drill logs and the results were acceptable. Where geophysical logs for such holes are available, they were used by MM&A geologists to verify the coal thickness and core recovery of 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.

Alpha Metallurgical Resources, Inc. Statement of Coal Resources and Reserves for the Marfork Mining Complex in Accordance with United States SEC Standards as of December 31, 2022 Central Appalachian Coal Basin West Virginia, USA MARSHAL MILLER & ASSOCIATES, INC. 35 Marfork has a lengthy history of operation and four currently active mines with no significant hydrologic concerns or material issues experienced in its history. Future mining is projected to occur in areas exhibiting similar hydrogeological conditions as past mining. Based upon the successful history of the operation with 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 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 core drilling sampling technique is for the coal core sample, once recovered from the core barrel, to be described then wrapped in a sealed plastic sleeve and placed into a covered 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 Marfork. 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 most core samples within the exploration database. However, it is reasonable to assume, given the sophistication 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. In addition to the steps taken to ensure the accuracy of the historical data as described above, Alpha reports that the company employs a detailed chain of custody process during their current sampling Alpha Metallurgical Resources, Inc. Statement of Coal Resources and Reserves for the Marfork Mining Complex in Accordance with United States SEC Standards as of December 31, 2022 Central Appalachian Coal Basin West Virginia, USA MARSHAL MILLER & ASSOCIATES, INC. 36 programs. This chain of custody process follows the sample from the time it is drilled until the final quality results are entered into a database for preparation of geologic models. 8.2 Lab Procedures Coal quality testing has been performed over many years by operating companies using different laboratories and testing regimens. Some of the samples have raw analyses and washabilities 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 ASTM International (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). 9 Data Verification 9.1 Procedures of Qualified Person MM&A reviewed the Alpha-supplied digital geologic database and supplemented the database with its own in-house records which have been maintained for both Alpha and previous operators of the Property. The database consists of data records, which include drill hole information for holes that lie within and adjacent to the Property and records for numerous supplemental coal seam thickness measurements. Once the initial integrity of the database was established, stratigraphic columnar sections were generated using cross-sectional analysis to establish or confirm coal seam correlations. Geophysical logs were used wherever available to assist in confirming the seam correlation and to verify proper seam thickness measurements and recovery of coal samples. Additionally, an audit of the Alpha digital database was conducted by comparing seam depths, coal, and parting thicknesses in the database against the source drill logs and the results were acceptable. After establishing and/or verifying proper seam correlation, seam data control maps and geological cross-sections were generated and again used to verify seam correlations and data integrity. Once the database was fully vetted, seam thickness, base-of-seam elevation, roof and floor lithology, and overburden maps were independently generated for use in the mine planning process.

Alpha Metallurgical Resources, Inc. Statement of Coal Resources and Reserves for the Marfork Mining Complex in Accordance with United States SEC Standards as of December 31, 2022 Central Appalachian Coal Basin West Virginia, USA MARSHAL MILLER & ASSOCIATES, INC. 37 Coal quality 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 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 cannot always be discovered. The greater the density of the samples taken, the less the risk. Once an area is identified as being of interest for inclusion in the mine plan, additional samples are taken to help reduce the risk in those 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 Marfork Property. The 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) and provided by Alpha 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 basic statistical analyses of the coal quality datasets, including Alpha Metallurgical Resources, Inc. Statement of Coal Resources and Reserves for the Marfork Mining Complex in Accordance with United States SEC Standards as of December 31, 2022 Central Appalachian Coal Basin West Virginia, USA MARSHAL MILLER & ASSOCIATES, INC. 38 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. As shipped analyses of the coal from Marfork were reviewed to verify that the coal quality and characteristics were as expected. The Marfork Property has a long history of saleable production, in the 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); 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.

Statement of Coal Resources and Reserves for the Marfork Mining Complex in Accordance with United States SEC Standards as of December 31, 2022 Central Appalachian Coal Basin West Virginia, USA MARSHAL MILLER & ASSOCIATES, INC. 39 11 Mineral Resource Estimates MM&A created independent geologic models to define the coal resources at Marfork. Coal resources were estimated as of December 31, 2022. 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 all 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 Marfork Eagle 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. 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 using histograms, as seen in Figure 11-1, color coded scatter plots showing the geospatial positioning of the borings, Figure 11-2, and trend analysis.

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 to represent the data set across a continuous spectrum.

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 Eagle seam data for the Marfork Mining Complex. DHSA provides hole to hole spacing values, these distances need to be converted to radius from a central point to compare to the historical standards. A summary of the radius data is shown in Alpha Metallurgical Resources, Inc.

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. Figure 11-4: Result of DHSA for the Eagle Seam Present in the Marfork Mining Complex Table 11-2: DHSA Results Summary for Radius from a Central Point Model: Measured Radial Distance (10% Relative Error) Indicated Radial Distance (20% Relative Error) Inferred Radial Distance (50% Relative Error) (Miles) (Miles) (Miles) Gaussian: 0.46 0.87 2.10 Spherical: 0.45 0.82 1.96 Exponential: 0.43 0.77 1.79 Comparing the results of the DHSA to the historical standards, it is evident that the historical standards are more conservative than even the most conservative DHSA model with regards to determining measured resources. The Spherical model recommends using a radius of 0.45 miles for measured resources compared to the historical value of 0.25 miles. With respect to indicated resources the DHSA falls in line closely with the historical standards. The Spherical model recommends using a radius 0.82 miles, while the Gaussian model recommends a radius of 0.87 miles and Exponential model recommend a radius of 0.77 miles. These values line up closely with 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 United States Geological Survey Circular 891 rather than use the results of the DHSA.

These resources, formally identified as resources exclusive of reserves, are in the: Chilton, Upper, Middle and Lower Cedar Groves, Powellton, Eagle, Glen Alum Tunnel, Beckley, and Fire Creek seams. Reasons which may preclude elevation of resources to reserves include, but are not limited to: 1. Limited availability of quality information to document coal seam market characteristics. a. Chilton Seam – Map 1: limited metallurgical analysis. - The Lower Winifrede and above coal seams in the Workman Eagle 2 Permit lack coal quality information and are deemed a resource. 2. Coal quality inconsistent with typical preferred market properties. a. Chilton Seam – Map 1: historically not a coking coal, sulfur >1%. 3. Isolation of resource blocks in which seam access costs are cost prohibitive at the time of the study. a. Titan Middle Cedar Grove – Map 4: eastern resource block isolated from reserve by below cutoff coal thickness. b. Black King Lower Cedar Grove – Map 5: isolated block bound on three sides by abandoned mine workings. c. Black King Area Upper Cedar Grove – Map 3: physical locations for access not identified and engineering and evaluation not completed to be included in the LOM planning. d.

Laurel Creek Area Upper Eagle – Map 7B: physical locations for access not identified and engineering and evaluation not completed to be included in the LOM planning. f. Glen Alum Tunnel – Map 10: resource block located north of a sandstone washout. 4. Unfavorable economics at the PFS level, yet economics could become attractive in the future under different market conditions. a. 10-B Area Powellton Seam – Map 6: uncertain access through a sealed existing mine or a faceup where the surface is not controlled. b. Mountain Laurel Beckley – Map 11: below-drainage slope access and raw haul to coal processing. Alpha Metallurgical Resources, Inc.

Roland Beckley - Map 11: isolated block where additional mineral control is needed for access. 6. Mineability constraints due to over/under mining, underground conditions, and physical locations. a. Dow Fork Eagle – Map 9: inferred resource adjacent to inclusive LOM plan. b. Sycamore Eagle – Map 9: mine plan is not defined as whether deep mine or surface mine. Jurisdictional water determinations have not been completed for a surface assessment. c. Mountain Laurel Beckley – Map 11: two below-drainage coal blocks located on the north side of Beckley, West Virginia. Overburden depth is 360 feet to 920 feet. These blocks are questionable due to permitting and potential liability of a mine under an urban area with shopping malls, residential areas, Interstate and State highways. d. Mountain Laurel Fire Creek – Map 12: single coal block located approximately 70 feet to 110 feet below the Mountain Laurel Beckley. Would require an in-mine slope from the Beckley seam for access. 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 development 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 $130 per ton netback FOB loadout

Totals may not add due to rounding. 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 uncertainties as related to each class of mineral resources such as (1) seam thickness, (2) floor and roof conditions, (3) 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, and indicated 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 measured and indicated 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 Marfork 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 Marfork. 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 Marfork. 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 at a 6.0-percent moisture and represent the saleable product from the Property. Pricing data as provided by Alpha is described in Table 16-2. The pricing data assumes a flat-line long- term realization of $151 per short ton port pricing, with an average $118.75 per ton netback pricing reflective of the high-volatile product currently sold at Marfork, and $152 per short ton port loading with an average of $113.93 per short ton netback pricing reflective of the low-volatile product. A

Statement of Coal Resources and Reserves for the Marfork Mining Complex in Accordance with United States SEC Standards as of December 31, 2022 Central Appalachian Coal Basin West Virginia, USA MARSHAL MILLER & ASSOCIATES, INC. 51 portion of the surface mine production is also thermal product which assumes a flat-line long term realization of $140 per short ton with an average of $133.75 per ton netback pricing. The LOM blended average netback pricing for the Marfork reserves is $118.55 per ton. These estimates are based on long-term pricing published by third party sources and adjusted for quality and transportation. 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 The Marfork Mine Complex reserves are derived from multiple coal seams as shown on Figure 7-1 and Figure 7-2. Reserves are estimated for both surface and underground mining. Surface reserves were derived from multiple seams and underground reserves were derived from nine seams. The underground accessed seams include above drainage seams from the Hernshaw down to the Glen Alum Tunnel; the Beckley seam located below drainage east of the surface mines. Demonstrated reserve tons are listed in the discussion below. Tables 12-1 and 12-2 show the demonstrated tonnage by Proven and Probable status. Alpha Metallurgical Resources, Inc. Statement of Coal Resources and Reserves for the Marfork Mining Complex in Accordance with United States SEC Standards as of December 31, 2022 Central Appalachian Coal Basin West Virginia, USA MARSHAL MILLER & ASSOCIATES, INC. 52 12.2.1 Surface Reserves The Workman Creek surface operations are active mine 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 20.3 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 the permits are active to varying degrees except for 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. 12.2.2 Underground Reserves Demonstrated reserve tons are listed in the discussion below. 12.2.3 Laurel Hernshaw (Map 2) Laurel Hernshaw demonstrated reserves are 4.6 Mt clean recoverable tons. The Hernshaw seam is generally characterized by two benches of coal with an approximate 0.5-foot to 1.0-foot shale parting. The parting thickness increases and the seam splits in the southern portion of the reserve, forming the southern reserve boundary. The average Hernshaw seam thickness of the reserve is 4.7 feet. The roof and floor rock are typically shale. A localized sandstone channel is present in the immediate roof and in the floor in the northeast portion of the reserve. This area is not included as a reserve due to mine cuttability. 12.2.4 Coon/Ellis Upper Cedar Grove (UCG) (Map 3) Coon UCG demonstrated reserves are 0.8 Mt clean recoverable tons, and Ellis area demonstrated Reserves are 0.9 Mt clean recoverable tons. Coon reserves are the remaining, unmined portion of the Coon Cedar Grove deep mine and the Ellis reserve is located on the ridge south of Coon. The UCG is generally two benches separated by an approximate 1-foot to 3-foot parting. The parting thickness increases and the seam splits in the northeast portion of the reserve, forming the eastern Coon reserve boundary. The average seam thickness of the reserve is 5.4 to 6.1 feet. Roof rock is generally sandstone, and the floor is shale. The southern limit of reserves is marked by a sandstone channel that has cut into the seam, eroding most of the coal. The northern limit to the Ellis reserve is defined by less than 30-foot of interburden to the mined out Middle Cedar Grove seam. 12.2.5 Titan Middle Cedar Grove (MCG) (Map 4) Titan MCG Demonstrated reserves are 5.2 Mt clean recoverable tons. Republic surface mine has developed a faceup area for the Titan mine. The roof and floor rock are generally cuttable shale. The seam is generally 1 to 2 coal benches separated by thin partings. A third, lower bench is present in the western part of the reserve creating a thicker seam and coal. The average seam thickness of the reserve Alpha Metallurgical Resources, Inc. Statement of Coal Resources and Reserves for the Marfork Mining Complex in Accordance with United States SEC Standards as of December 31, 2022 Central Appalachian Coal Basin West Virginia, USA MARSHAL MILLER & ASSOCIATES, INC. 54 is 3.20 feet. Sulfur averages greater than 1% west of the reserve area, although MM&A has no coal quality analysis within the reserve. With no washed coal quality analysis within the reserve boundary, the reserve is classified as a Probable Reserve. 12.2.6 Low Gap Middle Cedar Grove (MCG) (Map 4) Low Gap MCG demonstrated reserves are 0.6 Mt clean recoverable tons. The reserve is located on the hilltop immediately north of the Marfork Office. The reserve is an extension of the Marsh Fork Mine, west of Low Gap that is below the crop line. The roof and floor rock are generally cuttable shale. Sandstone is present in the roof in the southeast area of the reserves and has reduced the coal/seam thickness. The seam is generally comprised of two coal benches separated by thin parting. A third, lower bench, is present in the central part of the reserve creating a thicker seam and coal. The average seam thickness of the reserve is 3.46 feet. 12.2.7 Black King Lower Cedar Grove (LCG) (Map 5) Black King LCG Demonstrated reserves are 9.9 Mt clean recoverable tons. The reserve is located adjacent to and north and west of the closed Black King 1 Mine. Roof rock is mostly sandstone, and the floor is cuttable shale. The northeast reserve limit is defined by a sandstone washout of the coal seam. The seam is generally one clean bench of coal. The average seam thickness of the reserve is 2.81 feet. An isolated seam block south of the Black King Mine is classified as a resource due to difficult reserve access. 12.2.8 Berwind Area Lower Cedar Grove Seam (LCG) (Map 5) Berwind LCG Demonstrated reserves are 2.2 Mt clean recoverable tons. The reserve is located west of Hazy Creek. Roof rock is thick sandstone, and the floor is cuttable shale. The seam is generally one clean bench of coal. The average seam thickness of the reserve is 2.8 feet. An isolated seam block northwest of the reserve is classified as a resource due to access through below cutoff coal. 12.2.9 Slip Ridge and Bee Tree Powellton Seam (Map 6) Slip Ridge area Powellton reserve is located north of the Brushy Fork Impoundment and south of Little Marsh Fork and would be accessed by two portals. Slip Ridge and Bee Tree Powellton seam demonstrated reserves are 0.6 Mt and 0.5 Mt clean recoverable tons, respectively. The seam is comprised of one coal bench generally void of any partings. Roof rock is shale and sandstone on the east portion of the reserve and the floor rock is shale and fireclay. The average seam thickness of the reserve is 2.7 to 2.9 feet. 12.2.10 Marfork/Workman Area Upper Eagle (Map 7A) The Workman Upper Eagle reserve is located between the Marfork Deep operations and Workman surface operation. The reserve will be accessed from the surface mine bench and extract coal between

Statement of Coal Resources and Reserves for the Marfork Mining Complex in Accordance with United States SEC Standards as of December 31, 2022 Central Appalachian Coal Basin West Virginia, USA MARSHAL MILLER & ASSOCIATES, INC. 55 the surface and highwall miner areas to the coal thickness cutoff. Demonstrated reserves are 0.9 Mt clean recoverable tons. The average seam thickness of the reserve is 2.93 feet. 12.2.11 Panther Eagle Seam (Map 9) Panther Eagle reserve is actively being mined. Demonstrated reserves are 3.8 Mt clean recoverable tons. The seam generally has two coal benches separated by a thin 0.15-foot to 0.30-foot parting. Roof rock is dominated by sandstone and may have washed out the upper coal bench where the seam thins below cutoff. The floor rock is mostly shale making the seam cuttable. The average seam thickness of the reserve is 3.16 feet. 12.2.12 Horse Creek and Clear Fork Eagle Seam (Map 9) Horse Creek and Clear Fork Eagle are the remaining reserve blocks to be mined from the active Horse Creek mine. Reserves were calculated for the blocks and the reserve is separated from Panther Eagle by a low coal area. The seam contains two coal benches separated by an approximately 0.3-foot parting. The roof rock is shale and sandstone, and the floor rock is generally shale. The average seam thickness of the reserve is 3.2 feet. 12.2.13 Black Eagle Mine - Eagle Seam (Map 9) Black Eagle reserve is actively being mined. Demonstrated reserves are 12.7 Mt clean recoverable tons. The seam contains two distinct coal benches with a parting up to 0.5 feet thick. The roof is mostly sandstone with localized thin shale between the seam and sandstone main roof. The floor is generally shale. The average seam thickness of the reserve is 3.5 feet. 12.2.14 Dow Fork Eagle Seam (Map 9) Dow Fork Eagle Demonstrated reserves are 10.1 Mt clean recoverable tons. The seam, consistent with other Eagle reserves, is two distinct coal benches separated by a parting. Parting is less than 1.0 foot in the west and northeast portions of the reserve. The parting thickness increases in the center portion of the reserve and eventually splits the seam creating the reserve southern limit. The roof rock is dominated by sandstone in the west and east with shale roof common in the center portion on the reserve. The floor rock is shale. The average seam thickness of the reserve is 4.5 feet. 12.2.15 Glen Alum Tunnel Seam (Map 10) Glen Alum Tunnel mine is developed and active in the Workman Creek area. The seam is composed of multiple coal benches and partings. The parting above the lower coal bench increases to over 15 feet in the center portion of the Property, splitting the reserve into two blocks. The reserve is bound by a sandstone channel that has eroded the coal seam to the north and outcrop to the south. Roof and floor rock is predominantly shale with isolated areas of sandstone. The average seam thickness of the reserve is 4.7 feet. Alpha Metallurgical Resources, Inc.

Demonstrated reserves are 26.2 Mt clean recoverable tons. Overburden thickness ranges from 600 feet to over 2,000 feet along the ridges. The roof is typically sandstone with areas of shale roof. The west and east reserve limits are bound by north-south trending sandstone seam washout zones. The closed and abandoned Bonny mine encountered small scale, localized seam washouts within the reserve. Additional unidentified seam washouts are likely within the reserve. The floor rock is generally shale. Previous mining in the Bonny and Beckley mines indicate in situ horizontal stress and methane gas will be present. The average seam thickness of the reserve is 4.3 feet. 12.3 Qualified Person’s Estimates The coal reserves, as shown in Table 12-2, are based on a technical evaluation of the geology and a preliminary feasibility study of the coal deposits. 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 106.2 Mt of proven and probable marketable coal reserves. The maps included in Appendix C reflect mining depletion at the time of the resource/reserve calculation taken from Alpha mine maps as of September 30, 2022. Mine depletion tonnages were supplied by Alpha through the end of 2022, and MM&A deducted this historical production from the mapped reserves to estimate reserves as of December 31, 2022.

Coal quality is based on a weighted average of laboratory analysis from core holes. The combination of surface and inherent moisture is modeled at 6.0-percent. 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. Raw quality and some volatile matter analysis not available for Workman Creek. Workman Creek surface reserves were priced at 70% High-Vol. A and 30% thermal product. . 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. Totals may not add due to rounding. 12.4 Qualified Person’s Opinion The estimate of coal reserves was determined in accordance with the SEC S-K1300 regulations that became effective for the first fiscal year falling on or after January 1, 2021. The LOM mining plan for Marfork 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 Marfork coal reserves. 13 Mining Methods Twenty underground mining 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 2064, while surface and highwall miner operations are projected to be exhausted in 2033 and 2035, respectively.

Statement of Coal Resources and Reserves for the Marfork Mining Complex in Accordance with United States SEC Standards as of December 31, 2022 Central Appalachian Coal Basin West Virginia, USA MARSHAL MILLER & ASSOCIATES, INC. 58 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 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 Marfork. 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 Marfork Property by Alpha and its predecessors have been on-going for many years. 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. 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. The Marfork Mining Complex currently operates four underground mines with a total of seven (7) operating sections. The Horse Creek Eagle mine is phasing out of production as reserves deplete and one of the operating sections will be introduced into Panther Eagle Mine. The Glen Alum mine is in the Workman Creek surface area and is currently active with one operating section. The projected underground mines are set up similarly to the currently active operation. Black Eagle will operate three production sections, Panther Eagle will operate two production sections and the Glen Alum Mine will operate two production sections. All sections are configured with dual continuous miners in a super section operation. In all cases, mines are forecasted to produce coal two shifts each day. Production is scheduled Monday through Friday each week, and every other Saturday. As shown in Table 13-1, the twenty areas planned for underground mines produce coal until 2064. Clean coal production varies directly with coal thickness.

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 Alpha Metallurgical Resources, Inc. Statement of Coal Resources and Reserves for the Marfork Mining Complex in Accordance with United States SEC Standards as of December 31, 2022 Central Appalachian Coal Basin West Virginia, USA MARSHAL MILLER & ASSOCIATES, INC. 64 also been documented. The present mine plan consists of six permits: Middle Fork, Collins Fork, Turkey Foot, Center Contour, Long Ridge, and Eagle #2. 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 burrow long holes in the thicker seams exposed in the highwall. Where vertical elevation differences exceed 500 feet, 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. The ability to spoil on the previous Collins Fork impoundment provided needed spoil room. Ongoing permitting to increase hollowfill capacity in the southern portion of Workman is expected to provide additional spoil room but is dependent on United States Army Corps of Engineers (USACE) approval . Expansion of mining to the west would benefit from hollowfills in the Sycamore Creek drainage. High 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 and also does not result in longer haul distances on grade. 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.

Alpha Metallurgical Resources, Inc. Statement of Coal Resources and Reserves for the Marfork Mining Complex in Accordance with United States SEC Standards as of December 31, 2022 Central Appalachian Coal Basin West Virginia, USA MARSHAL MILLER & ASSOCIATES, INC. 65 To shorten haul distances, a “cut-thru” is proposed in the Long Ridge permit. The cut-thru would provide shorter haul distances to the Workman Creek coal handling facility and allow better distribution of mine spoil so that potential expansion westward can be achieved. Workman operates four large hydraulic excavators, three Caterpillar Inc. (Cat®) 993 loaders and nine D11 track bulldozers with a production capacity in excess of 40 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. Delays in hollowfill approval will likely encourage highwall mining of reserves that would otherwise be surface mined. The mine is expected to employ 270 operators in the surface mining phase and highwall mining phases of the operation. At the above production level exhaustion of the reserves is expected to be in year 2035. 13.4.2 Underground Mines 13.4.2.1 Panther Eagle Mine (Map 9) The Panther Eagle Mine is a unique operation that has one super section production unit and one mobile bridge conveyor production section in operation. The mine is operating in the Eagle Seam. The location is near the Marfork Preparation Plant with its run-of-mine (ROM) product transported by conveyor belt to the plant’s Raw Coal Stockpiles. The mine produces metallurgical grade coal from leased mineral property. The mine started production in 2017. One production unit utilizes a mobile bridge unit in lieu of shuttle cars while the other is a traditional super section. Production is scheduled for approximately 265 days each year, which represents production on Monday through Friday plus every other Saturday. On each day, production sections are scheduled to produce coal on two shifts. The sections are configured as super sections with two continuous miners used for production on each section. Productivity is planned at the rate of 240 feet of advance per shift on the super section and 193 feet per shift from the bridge unit. Principal production equipment for the super section includes two continuous miners, two roof bolters, four shuttle cars, and one scoop. Coal is extracted from the production face with the continuous miners and hauled to the mine conveyor in shuttle cars. At the conveyor belt, the coal is discharged from the shuttle cars onto a feeder breaker for transfer onto the conveyor. The conveyors carry the coal to the outside, where it is transported to the Raw Coal Stockpiles at the preparation plant. Alpha Metallurgical Resources, Inc.

Coal is extracted from the production face with the continuous miners and hauled to the mine conveyor in shuttle cars. At the conveyor belt, the coal is discharged from the shuttle cars onto a feeder breaker for transfer onto the conveyor. The conveyors transport the run of mine coal to the portal area, where product is stockpiled. Coal is then transported via highway truck haulage to the Marfork Preparation Plant where it is processed and loaded into CSX rail for transport to the consumer. Plans are in place to relocate the stockpile to a location across the Big Coal River from the portal area and directly across from the entrance to the Marfork Complex. The relocation will allow off road trucks to be used to transport the product for a distance of 2.2 miles on mine roads to the raw coal stockpile. Currently, highway trucks are used to transport the Black Eagle product for a distance of 2.7 miles. Mine workings have developed up to the location of two ventilation vertical shafts for providing ventilation to support three continuous miner sections through its assignment. Google Earth imagery indicates construction activity at the surface location of the air shafts in October 2022.

The plant was originally constructed in 1994 and received its latest upgrade in 2019.1 The plant produces a typical product with an ash content of 6.98% and typical sulfur content of 1.05% at a utilization rate of 57.66% in 2022. The infrastructure includes four (4) distinct raw coal stockpiles and seven (7) distinct clean coal stockpiles. The plant itself includes separation equipment including a heavy media vessel, cyclones, froth flotation, spirals, centrifugal dryers, screens, pumps, and sumps. The plant design feed rate is 2,400 tons per hour. Coarse and fine refuse are disposed at the Brushy Branch Impoundment and coarse refuse disposal is supplemented at the Low Gap Refuse Disposal Facility. Plant feed can be blended from the different stockpiles and plant products can be blended during the loading process. The flood railroad loadout is serviced by the CSX rail system. The empty train is cut once to create two strings for loading a 150-car unit train. Coal is recovered from the clean coal stockpiles by a reclaim belt located in a tunnel beneath the stockpiles. Processes and equipment are typical of those used in the coal industry and are in use in nearly all plants in the Central Appalachian Basin. 14.2 Requirements for Energy, Water, Material and Personnel Personnel have historically been sourced from the surrounding communities in Raleigh, Kanawha, Fayette, and Boone Counties, and have proven to be adequate in numbers to conduct processing operations at Marfork. 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 American Electric Power. The service industry in the areas surrounding the mine complex has historically provided supplies, equipment repairs and fabrication, etc. 1 Coal Age Magazine, October 2021, Prep Plant Census Alpha Metallurgical Resources, Inc.

Haul roads, primary roads, and conveyor belt systems account for transport from the various mine sites to the preparation plant. This practice will continue for future reserves. 15.1 Marfork Preparation Plant The preparation plant and associated refuse disposal areas have been established and maintained to provide a modern coal processing facility. Product flexibility is available with the in-bound product transportation systems that maximize the ability of the facility to reach regional reserves. Unique to the Marfork infrastructure is an existing transportation system that utilizes conveyor belts in underground mines as well as surface conveyors to transport raw coal to the facility for processing. This allows the plant ability to bring feed from considerable distance without incurring the cost of trucking over highways. Additionally, the rock content of the mine product does not impact the transportation cost as much as a trucking cost due to the efficiency of the conveyors. Product flexibility includes surface and underground mine production that is processed or shipped directly to the CSX rail system. The various areas and different seams provide a method to offer a wide variety of coal products for the customer. The coal handling ability in both the raw coal and clean coal areas allows for separating different types of coals for servicing different customer’s needs. The existing blending capabilities and the variety of coal seams reporting to the facility allows for a custom coal to be provided. Aerial photographs of existing facilities are shown in Figure 15-1 and Figure 15-2.

Statement of Coal Resources and Reserves for the Marfork Mining Complex in Accordance with United States SEC Standards as of December 31, 2022 Central Appalachian Coal Basin West Virginia, USA MARSHAL MILLER & ASSOCIATES, INC. 77 15.3 Underground Conveyor Coal Transport System Starting at the Workman’s Creek Coal Handling Facility, the coal transportation system consists of a conveyor belt system that travels through three non-producing coal mines to reach the Marfork Preparation Plant. The transportation system provides an economical alternative to trucking coal over large distances to reach existing preparation and shipping facilities. The Allen Powellton Mine is used to transport from the Workman’s Creek Coal Handling Facility to the mine’s original portal area in Horse Creek. The mine’s original stockpile area and overland conveyor to the portal in the Slip Ridge Cedar Grove Mine is utilized for the transportation system. The overall underground conveyor distance is 18,825 feet. The Horse Creek Coal Handling Facility provided coal transportation for the Horse Creek Eagle Mine and the Allen Powellton Mine. The Allen Powellton Mine recently ceased production in 2021 and the Horse Creek Eagle Mine is projected to close in 2023. With the mine closings, the coal transport system will be dedicated to the operations at Workman’s Creek. From the Horse Creek Coal Handling Facility, the coal is transported through the Slip Ridge Cedar Grove Mine located in the overlying Middle Cedar Grove Seam. The Slip Ridge Cedar Grove Mine has been idled since 2020. The underground conveyors transport the coal to the Brushy Creek Portal on the face of the impoundment. The overall underground conveyor distance is 17,363 feet. The conveyor system daylights and crosses the impoundment face to the Coon Cedar Grove Brushy Creek Portal on the other side of the valley, 1,570 feet. The Coon Cedar Grove Mine has been in non-producing status since 2021. This mine is in the Upper Cedar Grove Seam which is the seam above the Middle Cedar Grove seam. The underground conveyors transport the coal from the Impoundment Portal for 9,063 feet to the main portal area in Coon Branch which is located above the raw coal stockpiles. A series of surface conveyors transport the coal from the portal area 4,374 feet to the raw coal stockpiles. At the raw coal stockpiles, the coal can be placed in different stockpiles to provide product separation for blending purposes. The conveyor system covers 10.7 miles in total. Figure 15-3 is an aerial view of the conveyor system along the mine benches located in Coon Branch above the Marfork Preparation Plant. Alpha Metallurgical Resources, Inc.

A vertical shaft is constructed, and a feeder system is placed at the bottom of the shaft. The vertical shaft performs similar to a coal storage silo and allows the coal to be brought to the lower level in a controlled manner. Coal would be stockpiled at the mine sites as needed to separate the quality. Coal would be batched through the system to maintain separation for quality control. Estimated CAPEX costs for the facility are included within the financial model. 15.6 Proposed Overland Conveyor – Black Eagle Mine to Marfork Preparation Plant Not included within the CAPEX in the financial package is the cost of an overland conveyor system to transport coal from the existing Black Eagle Mine portal. Plans are in place to relocate the stockpile to a location across the Big Coal River from the portal area and directly across from the entrance to the Marfork Complex. The relocation will allow off road trucks to be used to transport the product for a distance of 2.2 miles on mine roads to the raw coal stockpile. Currently, highway trucks are used to transport the Black Eagle product for a distance of 2.7 miles to the Marfork Preparation Plant. The active Black Eagle Mine will operate until 2035 and will produce approximately 23,000,000 ROM tons during its life span. The Browns Branch Coal Handling Facility will service approximately 22,000,000 raw tons during its lifetime from the Black King LCG Mine.

Statement of Coal Resources and Reserves for the Marfork Mining Complex in Accordance with United States SEC Standards as of December 31, 2022 Central Appalachian Coal Basin West Virginia, USA MARSHAL MILLER & ASSOCIATES, INC. 80 Table 16-1: Quality Specifications HVA MV Ash (%) 6.73 6.50 Sulfur (%) 1.05 0.95 Volatile Matter (%) 32.11 29.12 The mine production serves the high-volatile and mid-volatile metallurgical markets. 16.2 Price Forecasts Company-wide pricing data as provided by Alpha from third party sources is described in Table 16-2. Note that not all products reflected in Table 16-2 will apply to every business unit. The pricing data assumes a flat-line long-term realization of $151 per short ton port pricing, with an average $118.75 per ton netback pricing reflective of the high-volatile product currently sold at Marfork, and $152 per short ton port loading with an average of $113.93 per short ton netback pricing reflective of the low- volatile product. A portion of the surface mine production is also thermal product which assumes a flat-line long term realization of $140 per short ton with an average of $133.75 per ton netback pricing. The LOM blended average netback pricing for the Marfork reserves is $118.55 per ton. These estimates are based on long-term pricing published by third party sources and adjusted for quality and transportation. The netback pricing represents adjustments made to published benchmark pricing based on quality and transportation. A large majority of the coal sold by Alpha and their Marfork Complex 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 Marfork Mine Complex.

With the volatility of the market, long- term contracts are not typically written. 17 Environmental Studies, Permitting and Plans, Negotiations or Agreements with Local Individuals 17.1 Results of Studies MM&A completed an environmental review in 2011 of the Massey properties acquired by Alpha, including those operations that were active at Marfork at that time. 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 Marfork 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, approximately 78 years of fine refuse disposal capacity and 66 years of coarse refuse disposal capacity at current rates have been identified, a significant portion of which is permitted and active. Securing additional coarse and fines capacity will be critical to execute the business plan as outlined in this TRS. The table below outlines the current estimated capacities and permits of Marfork’s coarse refuse disposal area and slurry impoundment.

Statement of Coal Resources and Reserves for the Marfork Mining Complex in Accordance with United States SEC Standards as of December 31, 2022 Central Appalachian Coal Basin West Virginia, USA MARSHAL MILLER & ASSOCIATES, INC. 82 The estimated facility life was based on a 10-year average of 466 acre-feet of slurry storage consumed per year and coarse placement of 4,000,000 refuse tons per year. Total facility capacity provided 66.7 years of coarse refuse storage and 77.5 years of fine storage capacity. Reclamation permit outlines indicate that both storage facilities have been permitted to the top of the ridgelines to maximize the storage capacity. The current MSHA approved impoundment design (Crest Elevation 2,200 feet) provides 21 years of slurry disposal. 17.3 Permit Requirements and Status All mining operations are subject to federal and state laws and must obtain permits to operate mines, coal preparation and related facilities, haul roads, and other incidental surface disturbances necessary for mining to occur. 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.2 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 are also 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, church, or similar structure unless written consent is first obtained from the owner of the structure. Where required, Alpha reports that such consents have been obtained where mining is proposed beyond the regulatory limits. 2 Monitored under the Applicant Violator System (AVS) by the Federal Office of Surface Mining.

Alpha Metallurgical Resources, Inc. Statement of Coal Resources and Reserves for the Marfork Mining Complex in Accordance with United States SEC Standards as of December 31, 2022 Central Appalachian Coal Basin West Virginia, USA MARSHAL MILLER & ASSOCIATES, INC. 83 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. The Marfork Mining Complex, 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) and the United States Fish and Wildlife Agency (USFW) involvement with state programs. The Mining permits currently held by Alpha on the Marfork Property are shown in Table 17-2. Alpha Metallurgical Resources, Inc.

Alpha Metallurgical Resources, Inc. Statement of Coal Resources and Reserves for the Marfork Mining Complex in Accordance with United States SEC Standards as of December 31, 2022 Central Appalachian Coal Basin West Virginia, USA MARSHALL MILLER & ASSOCIATES, INC. 85 17.4 Local Plans, Negotiations or Agreements MM&A found no indication of agreements beyond the scope of Federal or State Regulations. 17.5 Mine Closure Plans Applicable regulations require that mines be properly closed, and reclamation commenced immediately upon abandonment. In general, site reclamation includes removal of structures, backfilling, regrading, and revegetation of disturbed areas. For surface mines, much 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 Marfork Mining Complex is an operating facility; all necessary permits for current production have been obtained. MM&A knows of no reason that any permits revisions or new permits 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 Marfork Mining Complex in Accordance with United States SEC Standards as of December 31, 2022 Central Appalachian Coal Basin West Virginia, USA MARSHALL MILLER & ASSOCIATES, INC. 86 Alpha provided MM&A with information related to the number of currently operating production units at Marfork. 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. A summary of the estimated capital for the consolidated Marfork operations is provided in Figure 18-1 below. Total capital by mine is summarized in Table 18- 1.

Alpha Metallurgical Resources, Inc. Statement of Coal Resources and Reserves for the Marfork Mining Complex in Accordance with United States SEC Standards as of December 31, 2022 Central Appalachian Coal Basin West Virginia, USA MARSHALL MILLER & ASSOCIATES, INC. 89 18.2 Operating Cost Estimate Alpha provided historical costs and budgeted projections of operating costs for its active surface and highwall mines (Workman Creek), underground mines (Black Eagle, Panther Eagle, and Horse Creek Eagle, and the Glen Alum Tunnel) for MM&A’s review. MM&A used the historical 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, coal preparation plant processing, refuse handling, coal loading, property taxes and insurance and bonding and other direct mining costs. 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. Statutory sales-related costs are summarized in Table 18-2.

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, 2023. 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

Alpha Metallurgical Resources, Inc. Statement of Coal Resources and Reserves for the Marfork Mining Complex in Accordance with United States SEC Standards as of December 31, 2022 Central Appalachian Coal Basin West Virginia, USA MARSHALL MILLER & ASSOCIATES, INC. 91 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. Figure 19-1: Projection of Sales Tons Sales revenue is based on the 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 Marfork 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 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 Alpha Metallurgical Resources, Inc. Statement of Coal Resources and Reserves for the Marfork Mining Complex in Accordance with United States SEC Standards as of December 31, 2022 Central Appalachian Coal Basin West Virginia, USA MARSHALL MILLER & ASSOCIATES, INC. 92 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 6.0 to 8.5% of the sales revenue. The projection model also includes consolidated income tax calculations at Alpha’s Marfork 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 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. Alpha’s projected consolidated annual revenue for the Marfork operations is shown in the chart below: Figure 19-2: Consolidated Annual Revenue Projected consolidated revenue, cash costs, and EBITDA for the Marfork operations are expressed in dollars per ton in the graph below.

Statement of Coal Resources and Reserves for the Marfork Mining Complex in Accordance with United States SEC Standards as of December 31, 2022 Central Appalachian Coal Basin West Virginia, USA MARSHALL MILLER & ASSOCIATES, INC. 97 Consolidated cash flow from operations is positive throughout the projected operating period, apart from post-production years, due to end-of-mine reclamation spending. Consolidated cash flow from operations peaks at $178.9 million in 2024 and totals $3.6 billion over the project life. Capital expenditures total $185.8 million during the first five years and $1.2 billion over the project’s life. Consolidated Marfork 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 2064 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 15.04% 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 $777.2 million. Alpha is an active producer, and the financial model shows positive net cash flow for each year of the operating life of the Marfork 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 the purpose of confirming the economics for classification of coal reserves and not for Alpha Metallurgical Resources, Inc. Statement of Coal Resources and Reserves for the Marfork Mining Complex in Accordance with United States SEC Standards as of December 31, 2022 Central Appalachian Coal Basin West Virginia, USA MARSHALL MILLER & ASSOCIATES, INC. 98 purposes of valuing Alpha or its Marfork 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 15.04% 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 changes in sales price and operating cost estimates, and slightly sensitive to changes in capital cost estimates. 20 Adjacent Properties 20.1 Information Used No Proprietary information associated with neighboring properties was used as part of this study.

Alpha Metallurgical Resources, Inc. Statement of Coal Resources and Reserves for the Marfork Mining Complex in Accordance with United States SEC Standards as of December 31, 2022 Central Appalachian Coal Basin West Virginia, USA MARSHALL MILLER & ASSOCIATES, INC. 99 21 Other Relevant Data and Information MM&A performed a previous evaluation of all the Property in year 2021 for reserves effective as of December 31, 2021, for Alpha based on the (SEC) S-K 1300 regulations. Marfork was previously included in and referred to as Mid-West Virginia Underground and Workman was previously included in and referred to as Mid-West Virginia Surface. MM&A utilized this former evaluation as the basis of an updated study for the December 31, 2022 TRS. 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 Marfork 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 106.2 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). 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 Alpha Metallurgical Resources, Inc. Statement of Coal Resources and Reserves for the Marfork Mining Complex in Accordance with United States SEC Standards as of December 31, 2022 Central Appalachian Coal Basin West Virginia, USA MARSHALL MILLER & ASSOCIATES, INC. 100 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 13. 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. 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.

Statement of Coal Resources and Reserves for the Marfork Mining Complex in Accordance with United States SEC Standards as of December 31, 2022 Central Appalachian Coal Basin West Virginia, USA MARSHALL MILLER & ASSOCIATES, INC. 101 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 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 considering 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 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.

Risk reduction measures must be applied to reduce very high risks to a tolerable level. 22.2.6 Description of the Coal Property The Marfork complex is in Raleigh, Kanawha, Fayette and Boone Counties, West Virginia and is an active operation with four underground mines. The active surface mine operations (Workman Creek) employ contour, area, and highwall mining methods. The active underground operations (Black Eagle Mine, Panther Eagle, Horse Creek Eagle and Glen Alum Tunnel) utilize continuous mining production sections. This method provides continuity, preserving skilled work groups and enabling effective utilization of

Alpha Metallurgical Resources, Inc. Statement of Coal Resources and Reserves for the Marfork Mining Complex in Accordance with United States SEC Standards as of December 31, 2022 Central Appalachian Coal Basin West Virginia, USA MARSHALL MILLER & ASSOCIATES, INC. 105 existing production equipment. The active and projected mines are located above and below drainage and as such are accessed via a combination of drifts, box cuts, shafts, and slopes. 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 6.8, 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 Moderate $2-10 MM 1, 12 2, 8, 14 3, 4 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 several 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 Marfork Mining Complex in Accordance with United States SEC Standards as of December 31, 2022 Central Appalachian Coal Basin West Virginia, USA MARSHALL MILLER & ASSOCIATES, INC. 106 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. 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. 2 5 10 Develop mine plan to provide readily available alternate mining locations to sustain expected production level; modify coal sales agreements to reflect coal quality. 2 3 6 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.

Interruption of production and delayed implementation of replacement production from new mines. Comply quickly with testing, treatment and other actions required; continue excellent compliance performance within existing permits. 3 4 12 Establish and maintain close and constructive working relationships with regulatory agencies, local communities, and community action groups. 3 3 9 22.2.8.3 Regulatory Requirements Federal and state health and safety regulatory agencies occasionally amend mine laws and regulations. The impact is industry wide. Mining operators and regulatory agencies have been able to adapt successfully to evolving health and safety requirements. Table 22-7: Regulatory Requirements (Risk 5) Aspect Impact Control Measures Initial Risk Level Mitigation Measures Residual Risk Level P C R P C R Federal and state mine safety and health regulatory agencies amend mine laws and regulations. Cost of training, materials, supplies and equipment; modification of mine examination and production procedures; modification of mining plans. Participate in hearings and workshops, when possible, to facilitate understanding and implementation; work cooperatively with agencies and employees to facilitate implementation of new laws and regulations. 4 3 12 Familiarity and experience with new laws and regulations results in reduced impact to operations and productivity and improved supplies and equipment options. 4 2 8 22.2.8.4 Market and Transportation Most of the current and future production is expected to be directed to domestic and international metallurgical markets. Historically, the metallurgical markets have been cyclical and highly volatile. Alpha Metallurgical Resources, Inc. Statement of Coal Resources and Reserves for the Marfork Mining Complex in Accordance with United States SEC Standards as of December 31, 2022 Central Appalachian Coal Basin West Virginia, USA MARSHALL MILLER & ASSOCIATES, INC. 108 Table 22-8: Market and Transportation (Risk 6) Aspect Impact Control Measures Initial Risk Level Mitigation Measures Residual Risk Level P C R P C R Volatile coal prices drop precipitously. Loss of revenue adversely affects profitability; reduced cash flow may disrupt capital expenditures plan. 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 leads 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 present in coal operations below drainage. Often the methane concentration in shallow coal seams is at such low levels that it can be readily managed with vigilance, and routine mine ventilation surveys. Very high methane concentrations may be present at greater depths. High

Alpha Metallurgical Resources, Inc. Statement of Coal Resources and Reserves for the Marfork Mining Complex in Accordance with United States SEC Standards as of December 31, 2022 Central Appalachian Coal Basin West Virginia, USA MARSHALL MILLER & ASSOCIATES, INC. 109 methane concentrations may require degasification of the coal seam to assure safe mining. Methane is not expected to be present in most of the Marfork 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. Table 22-11: Mine Fires (Risk 9) Aspect Impact Control Measures Initial Risk Level Mitigation Measures Residual Risk Level P C R P C R Mine fire at underground operation or plant stockpile fire. Injury or loss of life; potential loss of mine temporarily or permanently; damage to equipment and mine infrastructure. Inspection and maintenance of mine power, equipment and mine infrastructure; good housekeeping; frequent examination of conveyor belt entries; prompt removal of accumulations of combustible materials. 1 5 5 If spontaneous combustion conditions are present, enhanced monitoring and examination procedures will be implemented; mine design will incorporate features to facilitate isolation, containment, and extinguishment of spontaneous combustion locations. 1 4 4 Alpha Metallurgical Resources, Inc.

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. Table 22-12: Ground Control (Risk 10) Aspect Impact Control Measures Initial Risk Level Mitigation Measures Residual Risk Level P C R P C R Ground control issues cause roof failures, rib rolls, floor heave, etc. Injury or loss of life; catastrophic damage to equipment; production interruption. Regular inspection for change and signs of failure. Dynamic design of roof control plan and safety measures to honor observed conditions and exploration- based information; conservative pillar design. 4 3 12 Multiple operating sections to mitigate any lost production; availability of new working areas in case abandonment of section is required; availability of alternative roof control technologies in case of abrupt changes in mining conditions. 4 2 8 22.2.8.5.4 Availability of Supplies and Equipment The industry has periodically had trouble receiving timely delivery of mine supplies and equipment. Availability issues often accompanied boom periods for coal demand. Any future delivery of supplies and equipment delays are expected to be temporary with limited impact on production. Table 22-13: Availability of Supplies and Equipment (Risk 11) Aspect Impact Control Measures Initial Risk Level Mitigation Measures Residual Risk Level P C R P C R Disruption of availability for supplies and equipment. Temporary interruption of production. Force majeure provision in coal sales agreements to limit liability for delayed or lost sales. 3 2 6 Work closely with customers to assure delayed coal delivery rather than cancelled sales; monitory external conditions and increase inventory of critical supplies; accelerate delivery of equipment when possible. 3 1 3 22.2.8.5.5 Labor Work stoppage due to labor protests are unlikely and accompanied by limited impact should it occur. Strong employee relations and communications limit the exposure to outside protesters. Loss of

Coal quality is based on a weighted average of laboratory analysis from core holes. The combination of surface and inherent moisture is modeled at 6.0-percent. 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.
