Indicated mineral 
resource (coal) 

Inferred mineral resource 
(coal) 

That part of a mineral resource for which quantity and grade or quality are estimated on 
the basis of adequate geological evidence and sampling. The level of geological certainty 
associated with an indicated mineral resource is sufficient to allow a qualified person to 
apply modifying factors in sufficient detail to support mine planning and evaluation of the 
economic viability of the deposit. Because an indicated mineral resource has a lower level 
of confidence than the level of confidence of a measured mineral resource, an indicated 
mineral resource may only be converted to a probable mineral reserve. 

That part of a mineral resource for which quantity and grade or quality are estimated on 
the basis of limited geological evidence and sampling. The level of geological uncertainty 
associated with an inferred mineral resource is too high to apply relevant technical and 
economic  factors  likely  to  influence  the  prospects  of  economic  extraction  in  a  manner 
useful for evaluation of economic viability. Because an inferred mineral resource has the 
lowest  level  of  geological  confidence  of  all  mineral  resources,  which  prevents  the 
application  of  the  modifying  factors  in  a  manner  useful  for  evaluation  of  economic 
viability, an inferred mineral resource may not be considered when assessing the economic 
viability of a mining project, and may not be converted to a mineral reserve.

Measured mineral 
resource (coal) 

That part of a mineral resource for which quantity and grade or quality are estimated on 
the basis of conclusive geological evidence and sampling. The level of geological certainty 
associated with a measured mineral resource is sufficient to allow a qualified person to 
apply modifying factors, as defined in this section, in sufficient detail to support detailed 
mine  planning  and  final  evaluation  of  the  economic viability  of  the  deposit.  Because  a 
measured mineral resource has a higher level of confidence than the level of confidence 
of either an indicated mineral resource or an inferred mineral resource, a measured mineral 
resource may be converted to a proven mineral reserve or to a probable mineral reserve.

Mineral Interest 

Mineral  interests  are  real-property  interests  that  are  typically  perpetual  and  grant 
ownership to the oil & gas under a tract of land or the rights to explore for, develop, and 
produce oil & gas on that land or to lease those exploration and development rights to a 
third party 

Mineral reserve (coal) 

Mineral resource (coal) 

An estimate of tonnage and grade or quality of indicated and measured mineral resources 
that,  in  the  opinion  of  the  qualified  person,  can  be  the  basis  of  an  economically viable 
project.  More specifically, it is the economically mineable part of a measured or indicated 
mineral  resource,  which  includes  diluting  materials  and  allowances  for  losses  that  may 
occur when the material is mined or extracted. 

A concentration or occurrence of material of economic interest in or on the Earth's crust 
in  such  form,  grade  or  quality,  and  quantity  that  there  are  reasonable  prospects  for 
economic extraction. A mineral resource is a reasonable estimate of mineralization, taking 
into account relevant factors such as cut-off grade, likely mining dimensions, location or 
continuity  that,  with  the  assumed  and  justifiable  technical  and  economic  conditions,  is 
likely  to,  in  whole  or  in  part,  become  economically  extractable.  It  is  not  merely  an 
inventory of all mineralization drilled or sampled.

Natural gas liquids are components of natural gas that are liquid at the surface in field 
facilities or gas-processing plants. Natural gas liquids can be classified according to their 
vapor pressures as low (condensate), intermediate (natural gasoline), and high (liquefied 
petroleum  gas)  vapor  pressure.  Natural  gas  liquids  include  propane,  butane,  pentane, 
hexane,  and  heptane,  but  not  methane  and  ethane  since  these  hydrocarbons  need 
refrigeration to be liquefied. The term is commonly abbreviated as NGL.

Proved reserves that can be expected to be recovered through existing wells with existing 
equipment and operating methods 

Proved reserves or 
properties (oil & gas) 

Proved reserves are those quantities of oil & gas which, by analysis of geoscience and 
engineering  data,  can  be  estimated  with  reasonable  certainty  to  be  economically 
producible—from  a  given  date  forward,  from  known  reservoirs,  and  under  existing 
economic conditions, operating methods, and government regulations—prior to the time 
at  which  contracts  providing  the  right  to  operate  expire,  unless  evidence  indicates  that 
renewal is reasonably certain, regardless of whether deterministic or probabilistic methods 
are used for the estimation. The project to extract the hydrocarbons must have commenced 
or  the  operator  must  be  reasonably  certain  that  it  will  commence  the  project  within  a 
reasonable time.  

Proved undeveloped 
reserves (oil & gas) 

Proved reserves that are expected to be recovered from new wells on undrilled acreage or 
from existing wells where a relatively major expenditure is required for recompletion

Reserves are estimated remaining quantities of oil and natural gas and related substances 
anticipated  to  be  economically  producible,  as  of  a  given  date,  by  application  of 
development projects to known accumulations. In addition, there must exist, or there must 
be a reasonable expectation that there will exist, the legal right to produce or a revenue 
interest  in  the  production,  installed  means  of  delivering  oil  and  natural  gas  or  related 
substances to the market, and all permits and financing required to implement the project. 
Reserves  should  not  be  assigned  to  adjacent  reservoirs  isolated  by  major,  potentially 
sealing,  faults  until  those  reservoirs  are  penetrated  and  evaluated  as  economically 
producible.

ITEM 1. 

BUSINESS 

Introduction 

PART I 

We are a diversified natural resource company that generates operating and royalty income from the production and 
marketing of coal to major domestic and international utilities and industrial users as well as royalty income from oil & 
gas mineral interests located in strategic producing regions across the United States. The primary focus of our business is 
to maximize the value of our existing mineral assets, both in the production of coal from our mining assets and the leasing 
and development of our coal and oil & gas mineral ownership. In addition, we are positioning ourselves as a reliable energy 
provider for the future as we pursue opportunities that support the advancement of energy and related infrastructure.  We 
intend  to  pursue  strategic  investments  that  leverage  our  core  competencies  and  relationships  with  electric  utilities, 
industrial customers, and federal and state governments. We believe that our diverse and rich resource base and strategic 
investments will allow us to continue to create long-term value for unitholders. 

We are the largest coal producer in the eastern United States with seven operating underground mining complexes in 
Illinois, Indiana, Kentucky, Maryland, Pennsylvania, and West Virginia as well as a coal-loading terminal in Indiana on 
the Ohio River. We manage and report our coal operations under two regions, Illinois Basin and Appalachia. We market 
our coal production to major domestic and international utilities and industrial users. 

We own mineral and royalty interests in approximately 67,700 net royalty acres, including approximately 4,000 net 
royalty acres attributable to our equity interest in AllDale III, in premier oil & gas producing regions in the United States, 
primarily the Permian, Anadarko, and Williston Basins. While we own both oil & gas mineral and royalty interests, we 
refer to them collectively as mineral interests throughout our discussions of our business as the majority of our holdings 
are mineral interests. We market our oil & gas mineral interests for lease to Operators in those regions and generate royalty 
income from the leasing and development of those mineral interests. Reserve additions and the associated cash flows are 
expected to increase from the development of our existing mineral interests and through acquisitions of additional mineral 
interests.  

We have approximately 663.2 million tons of coal mineral reserves and 1.06 billion tons of coal mineral resources in 
Illinois, Indiana, Kentucky, Maryland, Pennsylvania and West Virginia. Substantially, all of our coal mineral resources 
and 557.7 million tons of our coal mineral reserves are owned or leased by Alliance Resource Properties, which are (a) 
leased or subleased to internal mining complexes or (b) near other internal and external coal mining operations but not yet 
leased. We market our coal mineral reserves and resources to the coal mining operations that are able to access them and 
generate royalty income from the leasing and development of those coal mineral reserves and resources. 

We have invested in energy and infrastructure opportunities including Ascend, Francis, Infinitum, and NGP ET IV as 

described below.  

In  addition,  through  our  technology  company,  Matrix  Group,  we  develop  and  market  industrial,  mining  and 

technology products and services worldwide. 

ARLP, a Delaware limited partnership, completed its initial public offering on August 19, 1999, and is listed on the 
NASDAQ Global Select Market under the ticker symbol "ARLP." We are managed by our sole general partner, MGP, a 
Delaware limited liability company, which holds a non-economic general partner interest in ARLP.  

Oil & Gas Acquisitions 

The following acquisitions enhance our ownership position in the Permian Basin and further our business strategy to 

grow our Oil & Gas Royalties segment.

Acquisition Agreement 

On January 27, 2023, we entered into a one-year collaborative agreement with a third party effective January 1, 2023, 
committing up to $35.0 million for the acquisition of oil & gas mineral interests in the Midland and Delaware basins. 
Under the agreement, the third party assisted us in the identification, evaluation, and acquisition of target oil & gas mineral 
interests. In exchange for these services, the third party received a participation share, partially funded by the third party, 
and was paid a periodic management fee. We acquired $13.2 million oil & gas mineral interests under the agreement in 
2023. On February 19, 2024, we renewed this agreement for an additional one-year term, committing up to $25.0 million. 

JC Resources 

On February 22, 2023, we acquired approximately 2,682 oil & gas net royalty acres in the Delaware Basin from JC 

Resources, a related party entity owned by Mr. Craft, for $72.3 million.  

Skyland 

On December 7, 2023, we acquired approximately 2,372 oil & gas net royalty acres predominantly in the Anadarko 
Basin, along with acreage in the Williston and Delaware Basins from Skyland and Haymaker for a combined purchase 
price of $14.5 million. 

Growth Investments and Opportunities 

The following investments in the advancement of energy and related infrastructure further our business strategy to 
develop  strategic  relationships  and  invest  in  attractive  opportunities  that  leverage  our  core  competencies  and  build 
platforms  for  future  lines  of  business  with  long-term  growth  and  cash  flow  generation.  For  more  information  on  our 
acquisitions  and  investments,  please  read  "Item  8.  Financial  Statements  and  Supplementary  Data—Note  3  – 
Acquisitions","—Note 11 – Variable Interest Entities" and "—Note 12 – Equity Investments" of this Annual Report on 
Form 10-K. 

Francis  

On April 5, 2022, we made a $20.0 million convertible note investment in Francis which converted to a preferred 
equity interest on April 1, 2023. Francis currently is active in the installation, management and operation of metered-for-
fee,  public-access  EV  charging  stations.  Francis  also  develops  and  constructs  EV  charging  stations  for  third-party 
customers. 

Ascend 

On September 6, 2023, we purchased $25.0 million of Series D Preferred Stock in Ascend. Ascend is a U.S.-based 
manufacturer  and  recycler  of  sustainable,  closed-loop  engineered  battery  materials  for  electric  vehicles.  Ascend  is 
currently constructing North America's first commercial-scale manufacturing facility located near Hopkinsville, Kentucky, 
that when complete, will produce enough cathode materials for 750,000 electric vehicles per year. 

Infinitum  

On September 8, 2023, we increased our investment in Infinitum to $66.6 million by purchasing  $24.6 million of 
Series  E  Preferred  Stock.  Infinitum  is  a  Texas-based  startup  developer  and  manufacturer  of  electric  motors  featuring 
printed circuit board stators which have the potential to result in motors that are smaller, lighter, quieter, more efficient 
and capable of operating at a fraction of the carbon footprint of conventional electric motors.  

Matrix Group 

Matrix Group provides a variety of technology products and services for our mining operations and certain industrial 
and  mining  technology  products  and  services  to  third  parties.  On  January  16,  2024,  Matrix  Design  entered  into  an 
agreement with Infinitum to jointly develop and distribute high-efficiency motors and advanced motor controllers designed 
specifically for the mining industry. Under the agreement, Matrix Design will integrate Infinitum's motor technology into 
mining equipment of our operating subsidiaries to provide performance validation in production environments for jointly

Coal Mining Operations 

Coal is used primarily for the generation of electric power and the production of steel but is also used for chemical, 
food,  and  cement  processing.  We  produce  bituminous  coal  from  our  underground  mines  that  is  sold  to  customers 
principally for electric power generation (thermal) and the production of steel (metallurgical). We have established long-
term relationships with customers through exemplary and consistent performance.

At December 31, 2023, our mining operations had access to approximately 663.2 million tons of coal mineral reserves 
and 1.06 billion tons of coal mineral resources in Illinois, Indiana, Kentucky, Maryland, Pennsylvania, and West Virginia. 
Substantially, all of our coal mineral resources and 557.7 million tons of our coal mineral reserves are owned or leased by 
Alliance Resource Properties and are currently leased or subleased or held for lease or sublease to our mining operations 
or others. We produce a diverse range of thermal and metallurgical coal with varying sulfur and heat contents, which 
enables us to satisfy the broad range of specifications required by our customers. In 2023, we sold 34.4 million tons of 
coal and produced 34.9 million tons. Of the 34.4 million tons sold, approximately 60% were leased from Alliance Resource 
Properties. The coal we sold in 2023 was approximately 3.6% low-sulfur coal, 33.4% medium-sulfur coal, and 63.0% 
high-sulfur coal. In 2023, approximately 80.9% of our tons sold were purchased by domestic electric utilities and 15.7% 
were sold into the international markets through brokered transactions. The balance of our tons sold was to third-party 
resellers  and  industrial  consumers.  For  tons  sold  to  domestic  electric  utilities,  100.0% were  sold  to  utility  plants  with 
installed pollution control devices. The Btu content of our coal ranges from 11,450 to 13,200.

We lease most of our coal mineral reserves and resources from Alliance Resource Properties or private parties and 
generally have the right to maintain leases in force until the exhaustion of mineable and merchantable coal located within 
the leased premises or a larger coal mineral reserve or resource area. These leases provide for royalties to be paid to the 
lessors at a fixed amount per ton or as a percentage of the sales price. Many leases require payment of minimum royalties, 
payable either at the time of the execution of the lease or in periodic installments, even if no mining activities have begun.  
These minimum royalties are normally credited against the production royalties owed to a lessor once coal production has 
commenced. 

Illinois Basin Operations 

Our Illinois Basin mining operations are located in western Kentucky, southern Illinois, and southern Indiana. As of 

December 31, 2023, we have 2,189 employees and we operate four active mining complexes in the Illinois Basin. 

Gibson Complex   

Our subsidiary, Gibson, operates the Gibson South mine, located near the city of Princeton in Gibson County, Indiana. 
The Gibson South mine is an underground mine and utilizes continuous mining units employing room-and-pillar mining 
techniques to produce low/medium-sulfur coal.  The Gibson South mine's preparation plant has throughput capacity of 
1,800 tons of raw coal per hour.  Production from the Gibson South mine is shipped by truck or transported by rail on the 
CSX or NS railroads from our rail loadout facility directly to customers or various transloading facilities, including our 
Mt. Vernon transloading facility, for barge delivery. Production from the mine began in April 2014. Gibson production in 
2023 was 5.3 million tons. 

River View Complex 

Our subsidiary, River View, operates the River View mine and the Henderson County mine. The River View mine is 
located in Union County, Kentucky and is currently the largest room-and-pillar coal mine in the United States. The River 
View  mine  began  production  in  2009  and  utilizes  continuous  mining  units  to  produce  medium/high-sulfur  coal  from 
multiple  seams.  The  Henderson  County  mine  is  located  in  Henderson  County,  Kentucky  and  is  currently  under 
development, with full production expected to begin in 2024 from the No. 9 seam. 

Both mines will utilize the existing preparation plant, refuse disposal, and loadout facilities.  River View's preparation 
plant  has  throughput  capacity  of  2,700  tons  of  raw  coal  per  hour.  Coal  produced  from  the  River  View  complex  is 
transported by overland belt to a barge loading facility on the Ohio River. River View coal production in 2023 was 9.9 
million tons. 

Hamilton Complex 

Our subsidiary, Hamilton, operates the Hamilton mine, located near the city of McLeansboro in Hamilton County, 
Illinois. The Hamilton mine is an underground longwall mining operation producing medium/high-sulfur coal. Longwall 
mining began in October 2014 and we acquired complete ownership and control in 2015. Hamilton's preparation plant has 
throughput capacity of 2,000 tons of raw coal per hour. Hamilton has the ability to ship coal from the Hamilton mine via 
the CSX, Evansville Western Railway, or NS rail directly to customers or various transloading facilities, including our Mt. 
Vernon transloading facility, for barge deliveries. Hamilton coal production in 2023 was 5.6 million tons. 

Warrior Complex 

Our subsidiary, Warrior, operates an underground mining complex located near the city of Madisonville in Hopkins 
County,  Kentucky.  The  Warrior  complex  was  opened  in  1985,  and  we  acquired  it  in  February 2003.  Warrior  utilizes 
continuous  mining  units  employing  room-and-pillar  mining  techniques  to  produce  medium/high-sulfur  coal.  Warrior's 
preparation plant has throughput capacity of 1,200 tons of raw coal per hour. Warrior's production is shipped via the CSX 
or PAL railroads or by truck directly to customers or potentially to various transloading facilities, including our Mt. Vernon 
transloading facility, for barge deliveries. Warrior coal production in 2023 was 4.4 million tons.

Mt. Vernon Transfer Terminal, LLC 

Our  subsidiary,  Mt.  Vernon,  leases  land  and  operates  a  coal-loading  terminal  on  the  Ohio  River  at  Mt. 
Vernon, Indiana. Coal is delivered to Mt. Vernon by both rail and truck. The terminal has a capacity of 8.0 million tons 
per  year  with  existing  ground  storage  of  approximately 200,000  tons.  In 2023,  the  terminal  loaded  approximately 3.6 
million tons for customers of Gibson and Hamilton. 

Appalachian Operations 

Our Appalachian mining operations are located in eastern Kentucky, Maryland, and West Virginia. As of December 

31, 2023, we had 1,014 employees and we operate three mining complexes in Appalachia. 

Tunnel Ridge Complex 

Our subsidiary, Tunnel Ridge, operates the Tunnel Ridge mine, an underground longwall mine in the Pittsburgh No. 8 
coal seam, located near Wheeling, West Virginia. Longwall mining operations began at Tunnel Ridge in May 2012. The 
Tunnel Ridge preparation plant has throughput capacity of 2,000 tons of raw coal per hour. Coal produced from the Tunnel 
Ridge mine is medium/high-sulfur coal and is transported by conveyor belt to a barge loading facility on the Ohio River. 
Tunnel Ridge has the ability through a third-party facility to transload coal from barges for rail shipment on the Wheeling 
and Lake Erie Railway with connections to the CSX and the NS railroads. Tunnel Ridge coal production in 2023 was 7.7 
million tons. 

Mettiki Complex 

The Mettiki Complex comprises the Mountain View mine located in Tucker County, West Virginia operated by our 
subsidiary Mettiki (WV) and a preparation plant located near the city of Oakland in Garrett County, Maryland operated 
by  our  subsidiary  Mettiki  (MD).  Mettiki  (WV)  began  longwall  mining  in  November 2006.  The  Mountain  View  mine 
produces low/medium-sulfur coal, which is transported by truck either to the Mettiki (MD) preparation plant for processing 
for shipment into the metallurgical coal market or otherwise, or directly to the coal blending facility at the Virginia Electric 
and Power Company Mt. Storm Power Station. The Mettiki (MD) preparation plant has throughput capacity of 1,350 tons 
of raw coal per hour. Coal processed at the preparation plant can be trucked to the blending facility at Mt. Storm or shipped 
via the CSX railroad, which provides the opportunity to ship into the domestic and international thermal and metallurgical 
coal markets. Mettiki WV coal production in 2023 was 0.8 million tons. 

MC Mining Complex 

The MC Mining Complex is located near the city of Pikeville in Pike County, Kentucky. We acquired the original 
mine in 1989. Our subsidiary, MC Mining, through our subsidiary, Excel operates the Excel Mine No. 5. Excel completed 
the development of Mine No. 5 in May 2020 and transitioned its employees and equipment from Mine No. 4 in July 2020. 
The  underground  operation  utilizes  continuous  mining  units  employing  room-and-pillar mining  techniques  to  produce 
low-sulfur coal. The existing preparation plant, which has throughput capacity of 1,000 tons of raw coal per hour, is utilized 
by Mine No. 5. Substantially all of the coal produced at MC Mining in 2023 met or exceeded the compliance requirements 
of Phase II of the Federal CAA (see "—Environmental, Health and Safety Regulations—Air Emissions" below). Coal 
produced from the mine is shipped via the CSX railroad directly to customers or various transloading facilities on the Ohio 
River for barge deliveries, or by truck directly to customers or various docks on the Big Sandy River for barge deliveries. 
MC Mining coal production in 2023 was 1.2 million tons.  

Coal Marketing and Sales 

We sell coal to an established customer base through opportunities as a result of existing business relationships or 
through  formal  bidding  processes.  As  is  customary  in  the  coal  industry,  we  have  entered  into  long-term  coal  supply 
agreements with many of our customers. These arrangements are mutually beneficial to our customers and us in that they 
provide greater predictability of sales volumes and sales prices. Although some utility customers have appeared to favor a 
shorter-term  contracting  strategy,  in  2023  approximately  93.4%  and  92.0%  of  our  sales  tonnage  and  total  coal  sales, 
respectively, were sold under long-term contracts with committed term expirations ranging from 2024 to 2029.  Our initial 
2024 guidance includes 32.5 million priced and committed tons for delivery in 2024. The contractual time commitments 

7 

 
 
 
 
 
 
 
 
 
 
 
for customers to nominate future purchase volumes under these contracts are typically sufficient to allow us to balance our 
sales commitments with prospective production capacity.  

The provisions of long-term contracts are the results of both bidding procedures and extensive negotiations with each 
customer. As a result, the provisions of these contracts vary significantly in many respects, including, among other factors, 
price adjustment features, price, and contract reopener terms, permitted sources of supply, force majeure provisions, and 
coal  qualities  and  quantities.  A  portion  of  our  long-term  contracts  is  subject  to  price  adjustment  provisions,  which 
periodically permit an increase or decrease in the contract price, typically to reflect changes in specified indices or changes 
in production costs resulting from regulatory changes, or both. These provisions, however, may not ensure that the contract 
price  will  reflect  every  change  in  production  or  other  costs.  Failure  of  the  parties  to  agree  on  a  price  pursuant  to  an 
adjustment or a reopener provision can, in some instances, lead to the early termination of a contract. Some of the long-
term contracts also permit the contract to be reopened for renegotiation of terms and conditions other than pricing terms, 
and where a mutually acceptable agreement on terms and conditions cannot be concluded, either party may have the option 
to terminate the contract. Long-term contracts typically stipulate procedures for the transportation of coal, quality control, 
sampling,  and  weighing.  Most  contain  provisions  requiring  us  to  deliver  coal  within  stated  ranges  for  specific  coal 
characteristics  such  as  heat,  sulfur,  ash,  moisture,  grindability,  volatility,  and  other  qualities.  Failure  to  meet  these 
specifications can result in economic penalties, rejection or suspension of shipments, or termination of the contracts. While 
most of the contracts specify the approved seams and/or approved locations from which the coal is to be mined, some 
contracts allow the coal to be sourced from more than one mine or location. Although the volume to be delivered pursuant 
to a long-term contract is stipulated, the buyers often have the option to vary the volume within specified limits. Coal 
contracts typically contain force majeure provisions allowing for the suspension of performance by either party for the 
duration  of  specified  events.  Force  majeure  events  include  but  are  not  limited  to  unexpected  significant  geological 
conditions and weather events that may disrupt transportation. Depending on the language of the contract, some contracts 
may terminate upon an event of force majeure that extends for a certain period. 

The international coal market has been a part of our business with indirect sales to end-users in Europe, Africa, Asia, 
North America, and South America. Our sales into the international coal market are considered exports and the majority 
are  made  through  brokered  transactions.  During  the  years  ended  December  31,  2023,  2022,  and  2021,  export  tons 
represented  approximately  15.7%,  12.5%,  and  12.5%  of  tons  sold,  respectively.  Because  title  to  our  export  shipments 
typically transfers to our brokerage customers at a point that does not necessarily reflect the end-usage point, we attribute 
export tons to the country with the end-usage point, if known. 

Reliance on Major Customers 

In 2023, we derived more than 10% of our total revenue from each of American Electric Power and Tennessee Valley 
Authority. We did not derive 10% or more of our revenues from any other single customer. For more information about 
these customers, please read "Item 8. Financial Statement and Supplemental Data—Note 22 – Concentration of Credit 
Risk and Major Customers." 

Coal Competition 

The  coal  industry  is  intensely  competitive.  The  most  important  factors  on  which  we  compete  are  coal price,  coal 
quality (including sulfur and heat content), reliability and diversity of supply, and transportation costs from the mine to 
the customer. We are the largest coal producer in the eastern United States. Our principal competitors include American 
Consolidated Natural Resources Inc., CONSOL Energy, Inc., Alpha Metallurgical Resources, Inc., Foresight Energy LP, 
and Peabody Energy Corporation. We also compete directly with smaller producers in the Illinois Basin and Appalachian 
regions.  In  addition,  we  seek to  export  a  portion of our  coal  into  the  international  coal markets  and  we  compete  with 
companies that produce coal from one or more foreign countries. 

The price per ton for our export coal sales is influenced by many factors, such as global economic conditions, weather 
patterns, and global supply and demand, among others. The price per ton for our domestic coal sales are primarily linked 
to coal consumption patterns of domestic electricity-generating utilities, which in turn are influenced by economic activity, 
government regulations, weather, and technological developments, as well as the location, quality, price and availability 
of competing sources of fuel and alternative energy sources such as natural gas, nuclear energy, petroleum and renewable 
energy sources for electrical power generation.

Coal Transportation 

Our coal is transported from our mining complexes to our customers by barge, rail, and truck, reflecting important 
flexibility advantages in supplying our customers. Depending on the proximity of the customer to the mining complex and 
the transportation available for delivering coal to that customer, transportation costs can be a substantial part of the total 
delivered cost of a customer's coal. Consequently, the availability and cost of transportation constitute important factors 
in  the  marketability  of  coal.  We  believe  our  mines  are  located  in  favorable  geographic  locations  that  minimize 
transportation  costs  for  our  customers,  and  in  many  cases,  we  can  accommodate  multiple  transportation  options.  Our 
customers typically negotiate and pay the transportation costs from the mining complex to the destination, which is the 
standard practice in the industry. Approximately 50.2% of our 2023 sales volume was initially shipped from the mining 
complexes by barge, 32.1% was shipped from the mining complexes by rail, and 17.7% was shipped from the mining 
complexes by truck. The rates set by and available capacity of the transportation company serving a particular mine or 
customer  may  affect,  either  adversely  or favorably, our marketing  efforts  concerning  coal  produced from  the  relevant 
mining complex. With respect to our export volumes from the United States to other countries, we generally sell coal to 
our customers at an export terminal in the United States and we are responsible for the cost of transporting coal to the 
export terminals. Our export customers generally negotiate and pay for ocean vessel transportation. 

Mineral Interest Activities 

Our mineral interest activities include both oil & gas and coal mineral interests. Our oil & gas mineral interest business 
includes all activities related to the oil & gas mineral interests held directly or indirectly by Alliance Minerals and includes 
Alliance Minerals' equity interest in AllDale III. Our mineral interests are primarily located on private lands in three basins, 
which are also our areas of focus for future development by operators. These include the Permian (Delaware and Midland), 
Anadarko (SCOOP/STACK), and Williston (Bakken) Basins. Our developed and undeveloped net acres standardized to a 
1/8th royalty equate to more than 67,745 oil & gas net royalty acres, including 3,969 oil & gas net royalty acres owned 
through our equity interest in AllDale III. 

Our coal mineral interests include substantially all of our coal mineral resources and 557.7 million tons of coal mineral 
reserves which are owned or leased by Alliance Resource Properties and are (a) leased or subleased to internal mining 
complexes or (b) near other internal and external coal mining operations but not yet leased.  Our coal mineral interests are 
located in both the Illinois Basin and the Appalachia Basin. 

Oil & Gas Royalties 

When our oil & gas mineral interests are leased, we typically receive an upfront cash payment, known as a lease 
bonus, and we retain a mineral royalty, which entitles us to receive a fixed percentage of the revenue or production from 
the oil & gas produced from the acreage underlying our interests, free of lease operating expenses and capital costs. A 
lessee can extend the lease beyond the initial lease term with continuous drilling, production, or other operating activities, 
or by making an extension payment. When production or drilling ceases, the lease terminates, allowing us to lease the 
exploration and development rights to another party. As an owner of mineral interests, we incur the initial cost to acquire 
our  interests  but  thereafter  only  incur  our  proportionate  share  of  production  and  ad  valorem  taxes.  Unlike  owners  of 
working  interests  in  oil  &  gas  properties,  we  are  not  obligated  to  fund  drilling  and  completion  costs,  lease  operating 
expenses, or plugging and abandonment costs associated with oil & gas production. 

The following chart summarizes the production of our oil & gas mineral interests for the year ended December 31, 

2023, 2022, and 2021, not including our equity interest in AllDale III:

The following map shows the location of our oil & gas mineral interests: 

Permian Basin—Delaware and Midland Basins 

The Permian Basin ranges from West Texas into southeastern New Mexico and is currently the most active area for 
horizontal drilling in the United States. The Permian Basin is further subdivided into the Delaware Basin in the west and 
the Midland Basin in the east. Based on geologic data and the ongoing development by operators, our mineral interests in 
the Permian Basin contain multiple producing zones of economic horizontal development including but not limited to the 
Wolfcamp, Spraberry, and Bone Spring formations. Our purchases of acreage located entirely in the Permian Basin through 
the  Belvedere,  Jase  and  JC  Resources  Acquisitions  demonstrate  our  commitment  to  continued  acquisition  of  mineral 
interests in the nation's highest growth oil & gas plays. 

Anadarko Basin—SCOOP and STACK Plays 

The SCOOP play (South Central Oklahoma Oil Province) is located in central Oklahoma in Grady, Garvin, Stephens, 
and McClain Counties. Based on geologic data and the ongoing development by operators, our mineral interests in the 
SCOOP play contain multiple producing zones of economic horizontal development including multiple Woodford benches 
and the Springer Shale. In addition, operators are also currently testing other formations in the area including the Sycamore, 
Caney, and Osage, which is also referred to as SCORE (Sycamore Caney Osage Resource Expansion). The STACK play 
(derived  from  Sooner  Trend,  Anadarko  Basin,  Canadian  and  Kingfisher  Counties)  is  located  in  central  Oklahoma  in 
Kingfisher, Canadian, Caddo, and Blaine Counties. Based on geologic data and the ongoing development by operators, 
our mineral interests in the STACK play contain multiple producing zones of economic horizontal development including 
but not limited to the Meramec and Woodford formations. 

10 

 
 
 
 
 
 
 
 
Williston Basin—Bakken 

The Williston Basin stretches from western North Dakota into eastern Montana. Based on geologic data and ongoing 
development by operators, our mineral interests contain multiple producing zones of economic horizontal development 
including the Bakken and Three Forks formations. 

Other 

Our  other  interests  are  comprised  primarily  of  mineral  interests  owned  in  the  Appalachia  Basin  that  stretches 
throughout most of Ohio, West Virginia, and Pennsylvania, and extends into other states. The Appalachia Basin's most 
active plays in which we have acreage are the Marcellus Shale and Utica plays, which cover most of Pennsylvania, northern 
West Virginia, and eastern Ohio. In addition to the interests held in the Appalachia Basin, we own a small number of 
mineral  interests  in  the  Tuscaloosa  Marine  Shale  play  in  Mississippi.  AllDale  III  also  owns  mineral  interests  in  the 
Haynesville Shale formation located in northwest Louisiana. 

Coal Royalties 

Our Coal Royalties segment includes approximately 557.7 million tons of reserves and substantially all of the 1.06 
billion  tons  of our  coal  mineral  resources.  Our  coal  mineral  reserves  and  resources  are  located  in  the  Appalachia  and 
Illinois Basins in the United States. We lease our reserves and resources to our mining complexes under long-term leases. 
Approximately 60% of our royalty-based leases have initial terms of five to 40 years, with substantially all lessees having 
the option to extend the lease for additional terms.  

Under our standard royalty lease, we grant the lessees the right to mine and sell our reserves and resources in exchange 
for royalty payments based on a percentage of the sale price or a fixed royalty per ton of coal mined and sold. Lessees 
calculate royalty payments due to us and are required to report tons of coal mined and sold as well as the sales prices of 
the extracted coal.

Minerals Interest Competition 

Many companies are engaged in the search for and the acquisition of coal and oil & natural gas interests, and there is 
a limited supply of desirable coal and oil & natural gas reserves. Our ability to acquire additional oil & gas mineral interests 
in the future will be dependent upon our ability to evaluate and select suitable properties and to consummate transactions 
in a highly competitive environment. Many of our competitors not only own and acquire oil & gas mineral interests but 
also  explore  for  and  produce  oil  &  gas  and,  in  some  cases,  conduct  midstream  and  refining  operations  and  market 
petroleum  and  other  products  on  a  regional,  national,  or  worldwide  basis.  By  engaging  in  such  other  activities,  our 
competitors may be able to develop or obtain information that is superior to the information that is available to us. In 
addition, because we have fewer financial and human resources than many companies in the oil & gas industry, we may 
be at a disadvantage in bidding for oil & gas properties. Further, oil & gas compete with other forms of energy available 
to customers, primarily based on price. These alternate forms of energy include electricity, coal, and fuel oils. Changes in 
the availability or price of oil & gas or other forms of energy, as well as business conditions, conservation, legislation, 
regulations, and the ability to convert to alternative fuels and other forms of energy, may affect the demand for oil & gas. 

We also face competition from land companies, coal producers, and international steel companies in purchasing coal 
mineral  reserves  and resources  as  well  as  royalty-producing  properties.  Our  mining  complexes  in  which  we  lease  our 
reserves compete with coal producers in various regions of the United States for domestic sales on the basis of coal price 
at the mine, coal quality, transportation cost from the mine to the customer, and the reliability of supply. Continued demand 
for our coal and the prices that our lessees obtain are also  affected by the demand for electricity and steel, as well as 
government regulations, technological developments, and the availability and the cost of generating power from alternative 
fuel sources, including nuclear, natural gas, wind, solar, and hydroelectric power. 

For additional information, please see "Item 1A. Risk Factors". 

Oil & Gas Minerals Interest - Seasonal Nature of Business 

Generally, demand for oil increases during the summer months and decreases during the winter months while demand 
for natural gas increases during the winter and summer months and decreases during the spring and fall months. Certain 
buyers of natural gas use natural gas storage facilities and purchase some of their anticipated winter requirements during 
the summer, which can lessen seasonal demand fluctuations. Seasonal weather conditions and lease stipulations can limit 
drilling and producing activities and other oil & gas operations in a portion of our leasing areas. These seasonal anomalies 
can pose challenges for the Operators in meeting well-drilling objectives and can increase competition for equipment, 
supplies, and personnel during the spring and summer months, which could lead to shortages and increase costs or delay 
operations.

Infinitum to jointly develop and distribute high-efficiency motors and advanced motor controllers designed specifically 
for  the  mining  industry.  Under  the  agreement,  Matrix  Design  will  integrate  Infinitum's  motor  technology  into  mining 
equipment  of  our  operating  subsidiaries  to  provide  performance  validation  in  production  environments  for  jointly 

14 

 
 
 
 
 
 
 
 
 
 
 
 
developed products and to improve our operational efficiency. Matrix Design will also work with Infinitum to market the 
jointly developed technology products to third parties worldwide. We acquired Matrix Design in September 2006.  Over 
the past 15 years, Matrix Group has become a leader in collision avoidance and proximity detection technologies, providing 
safety  and  productivity  solutions  for  mining  companies  worldwide,  while  extending  its  reach  into  other  industrial 
applications. 

Growth Investments and Opportunities 

Our  subsidiary,  AROP  II,  LLC,  and  its  subsidiary,  AROP  II  Investments,  LLC,  makes  strategic  investments  in 
attractive  opportunities  that  support  the  advancement  of  energy  and  related  infrastructure.  We  intend  to  pursue 
opportunities that leverage our core competencies and relationships with electric utilities, industrial customers, and federal 
and state governments. Our strategy is to continue to identify and make strategic investments in the advancement of energy 
and related infrastructure opportunities that may create new platforms for future lines of business with long-term growth 
and cash flow generation. As of December 31, 2023, we have made investments of $25 million in Ascend, $20 million in 
Francis, $66.6 million in Infinitum and $6.6 million (of a $25 million commitment) in NGP ET IV. In 2023, revenues from 
these investments were immaterial. 

Ascend is a U.S.-based manufacturer and recycler of sustainable, closed-loop engineered battery materials for electric 
vehicles.  Ascend  is  currently  constructing  North  America's  first  commercial-scale  manufacturing  facility  located  near 
Hopkinsville, Kentucky, that when complete, will produce enough cathode materials for 750,000 electric vehicles per year. 

Francis  is  currently  active  in  the  installation,  management  and  operation  of  metered-for-fee,  public-access  EV 

charging stations. Francis also develops and contracts EV charging stations for third-party customers. 

Infinitum is a Texas-based developer and manufacturer of electric motors featuring printed circuit board stators that 
have the potential to result in motors that are smaller, lighter, quieter, more efficient and capable of operating at a fraction 
of the carbon footprint of conventional electric motors. 

NGP ET IV focuses on investments that are part of the global transition toward a lower carbon economy by partnering 
with top-tier management teams and investing growth equity in companies that drive or enable the growth of renewable 
energy, the electrification of our economy, or the efficient use of energy.   

Environmental, Health, and Safety Regulations 

Our coal operations, and those of the operators on the properties in which we hold oil & gas mineral interests, are 

subject to extensive regulation by federal, state, and local authorities on matters such as: 

• 
employee health and safety; 
• 
permits and other licensing requirements for mining or exploration and production activities; 
• 
air quality standards; 
•  water quality standards; 
• 

• 
• 

• 

storage of petroleum products and substances that are regarded as hazardous under applicable laws or that, if 
spilled, could reach waterways or wetlands; 
plant and wildlife protection that could limit or prohibit mining or exploration and production activities; 
restrict  the  types,  quantities,  and  concentration  of  materials  that  can  be  released  into  the  environment  in  the 
performance of mining or exploration and production activities; 
initiate  investigatory  and  remedial  measures  to  mitigate  pollution  from  former  or  current  operations,  such  as 
restoration of waste ponds, mining areas, drilling pits, and plugging of abandoned wells; 
storage and handling of explosives; 

• 
•  wetlands protection; 
• 
• 

surface subsidence from underground mining; and 
the effects, if any, that mining has on groundwater quality and availability. 

15 

 
 
 
 
 
 
 
 
 
 
Failure to comply with environmental laws and regulations may result in the assessment of administrative, civil, and 
criminal  sanctions,  including  monetary  penalties,  the  imposition  of  strict,  joint  and  several  liability,  investigatory  and 
remedial obligations, and the issuance of injunctions limiting or prohibiting some or all of the operations on our properties. 
The regulatory burden on fossil-fuel industries increases the cost of doing business and consequently affects profitability. 
The trend in environmental regulation has been to place more restrictions and limitations on activities that may affect the 
environment, and thus, any changes in environmental laws and regulations or reinterpretation of enforcement policies that 
result in more stringent and costly obligations could increase our or our mineral interest operators' costs and adversely 
affect our performance. 

In addition, the utility industry is subject to extensive regulation regarding the environmental impact of its power 
generation activities, which has adversely affected the demand for coal. It is possible that new legislation or regulations 
may be adopted, or that existing laws or regulations may be differently interpreted or more stringently enforced, any of 
which could have a significant impact on our mining operations, our customers' ability to use coal, or the value of or 
amount of royalties received from our mineral interests. For more information, please see the risk factors described in 
"Item 1A. Risk Factors" below. 

We are committed to conducting mining operations in compliance with applicable federal, state, and local laws and 
regulations.  However,  because  of  the  extensive  and  detailed  nature  of  these  regulatory  requirements,  particularly  the 
regulatory  system  of  MSHA  where  citations  can  be  issued  without  regard  to  fault  and  many  of  the  standards  include 
subjective elements, it is not reasonable to expect any coal mining company to be free of citations. When we receive a 
citation,  we  attempt  to  promptly  remediate  any  identified  condition.  While  we  have  not  quantified  all  of  the  costs  of 
compliance with applicable federal and state laws and associated regulations, those costs have been and are expected to 
continue to be significant. Compliance with these laws and regulations has substantially increased the cost of coal mining 
for domestic coal producers. 

Expenditures for environmental matters have not been material in recent years. We have accrued for the present value 
of the estimated cost of asset retirement obligations and mine closings, including the cost of treating mine water discharge, 
when necessary. The accruals for asset retirement obligations and mine closing costs are based on permit requirements 
and the estimated costs and timing assumptions of asset retirement obligations and mine closing procedures. Although 
management believes it has made adequate provisions for all expected reclamation and other costs associated with mine 
closures, future operating results would be adversely affected if these accruals were insufficient. 

Mining Permits and Approvals 

Numerous governmental permits or approvals are required for mining operations. Applications for permits require 
extensive engineering and data analysis and presentation and must address a variety of environmental, health, and safety 
matters associated with a proposed mining operation. These matters include the manner and sequencing of coal extraction, 
the storage, use, and disposal of waste and other substances and impacts on the environment, the construction of water 
containment areas, and reclamation of the area after coal extraction. Meeting all requirements imposed by any of these 
authorities may be costly and time-consuming and may delay or prevent the commencement or continuation of mining 
operations. 

The permitting process for certain mining operations can extend over several years and can be subject to administrative 
and  judicial  challenges,  including  by  the  public.  Some required  mining  permits  are  becoming  increasingly  difficult  to 
obtain in a timely manner, or at all. We cannot assure you that we will not experience difficulty or delays in obtaining 
mining permits in the future or that a current permit will not be revoked. 

We are required to post bonds to secure performance under our permits. Under some circumstances, substantial fines, 
and penalties, including revocation of mining permits, may be imposed under the laws and regulations described above.  
Monetary sanctions and, in severe circumstances, criminal sanctions may be imposed for failure to comply with these laws 
and  regulations.  Regulations  also  provide  that  a  mining  permit  can  be  refused  or  revoked  if  the  permit  applicant  or 
permittee  owns  or  controls,  directly  or  indirectly  through  other  entities,  mining  operations  that  have  outstanding 
environmental violations. Although like other coal companies, we have been cited for violations in the ordinary course of 
our business, we have never had a permit suspended or revoked because of any violation, and the penalties assessed for 
these violations have not been material. 

16 

 
 
 
 
 
 
 
 
Mine Health and Safety Laws 

The  operation  of  our  mines  is  subject  to  FMSHA,  and  regulations  adopted  pursuant  thereto.  FMSHA  imposes 
extensive and detailed safety and health standards on numerous aspects of mining operations, including training of mine 
personnel, mining procedures, blasting, the equipment used in mining operations, and numerous other matters. MSHA 
monitors and rigorously enforces compliance with these federal laws and regulations. In addition, most of the states where 
we operate have state programs for mine safety and health regulation and enforcement. Federal and state safety and health 
regulations  affecting  the  coal  mining  industry  are  perhaps the  most  comprehensive  and rigorous  system  in  the  United 
States for the protection of employee safety and have a significant effect on our operating costs. Although many of the 
requirements primarily impact underground mining, our competitors in all of the areas in which we operate are subject to 
the same laws and regulations. 

FMSHA has been construed as authorizing MSHA to issue citations and orders pursuant to the legal doctrine of strict 
liability,  or  liability  without  fault,  and  FMSHA  requires  the  imposition  of  a  civil  penalty  for  each  cited  violation.  
Negligence  and  gravity  assessments,  along  with  other  factors,  can  result  in  the  issuance  of  various  types  of  orders, 
including orders requiring withdrawal from the mine or the affected area, and some orders can also result in the imposition 
of civil penalties. FMSHA also contains criminal liability provisions. For example, criminal liability may be imposed upon 
corporate operators who knowingly and willfully authorize, order, or carry out violations of the FMSHA, or its mandatory 
health and safety standards. 

The MINER Act significantly amended the FMSHA, imposing more extensive and stringent compliance standards, 
increasing criminal penalties, and establishing a maximum civil penalty for non-compliance, and expanding the scope of 
federal oversight, inspection, and enforcement activities. Following the passage of the MINER Act, MSHA has issued 
new or more stringent rules and policies on a variety of topics, including: 

sealing off abandoned areas of underground coal mines; 

• 
•  mine safety equipment, training, and emergency reporting requirements; 
• 
• 
• 
• 
• 

substantially increased civil penalties for regulatory violations; 
training and availability of mine rescue teams; 
underground "refuge alternatives" capable of sustaining trapped miners in the event of an emergency; 
flame-resistant conveyor belts, fire prevention and detection, and use of air from the belt entry; and 
post-accident two-way communications and electronic tracking systems. 

MSHA  continues  to  interpret  and  implement  various  provisions  of  the  MINER  Act,  along  with  introducing  new 

proposed regulations and standards. 

MSHA  has  finalized  a  number  of  rules  related  to  controlling  exposure  to  coal  mine  dust,  which  has  resulted  in 
progressively  stricter  exposure  limits  imposed  by  MHSA  regulations.  These  requirements  impose  a  number  of  dust 
monitoring  obligation  and  mine  ventilation  requirements  on  our  operations.  Compliance  with  these  rules  can result  in 
increased  costs  on  our  operations,  including,  but  not  limited  to,  the  purchasing  of  new  equipment  and  the  hiring  of 
additional personnel to assist with monitoring, reporting, and recordkeeping obligations. MSHA previously published a 
request for information regarding engineering controls and best practices to lower miners' exposure to respirable coal mine 
dust; however, to date no further action has been taken and we cannot predict what actions, if any, MSHA may take in 
response to this information request. 

MSHA has also published, and may continue to publish, various proposed rules or requests for information, which 

may result in additional rulemaking. For example: 

• 

• 

In June 2016, MSHA published a request for information on Exposure of Underground Miners to Diesel Exhaust.  
Following a comment period that closed in November 2016 for this matter, MSHA received requests for MSHA 
and the National Institute for Occupational Safety and Health to hold a Diesel Exhaust Partnership to address the 
issues covered by MSHA's 2016 request for information. The comment period for the request for information for 
the Diesel Exhaust Partnership closed in September 2020 and it is uncertain whether this will result in additional 
rulemaking. 
In July of 2023, MSHA published a proposed rule on respirable crystalline silica, most commonly found in the 
mining environment through quartz. The proposed rule would amend the existing MSHA standards to lower the 
permissible  exposure  limit  of  respirable  crystalline  silica,  as  well  as  set  forth  new  or  revised  standards  for 

17 

 
 
 
 
 
 
 
 
• 

• 

exposure  sampling,  corrective  actions,  medical  surveillance  for  metal  and  non-metal  miners,  and  respiratory 
protection requirements. The comment period on the proposed rule ended in August of 2023 and the final rule is 
expected in April 2024. 
In November 2020, MSHA published a proposed rule to revise Testing, Evaluation, and Approval of Electric 
Motor-Driven Mine Equipment and Accessories within underground mining environments. The comment period 
for the proposed rule closed in December 2020 and the final rule is expected in August 2024. 
In September 2021, MSHA published a proposed rule requiring that mine operators employing six or more miners 
develop and implement a written safety program for mobile and powered haulage equipment at surface mines 
and surface areas of underground mines (Safety Program for Surface Mobile Equipment). The comment period 
for the proposed rule closed in November 2021. However, MSHA reopened the rulemaking record for additional 
public comments. A virtual hearing was held in January 2022 and the comment period closed in February 2022. 
The final rule was released in December 2023, with an effective date of January 19, 2024. All mines subject to 
the rule are required to develop, implement, and periodically update a written safety program for surface mobile 
equipment (excluding belt conveyors) at surface mines and surface areas of underground mines. Compliance with 
the rule must be achieved by July 17, 2024. 

It  is  uncertain  whether  any  of  the  above  or  other  various  proposed  rules  or  requests  for  information  would  have 

material impacts on our operations or our costs of operation. 

Subsequent  to  the  passage  of  the  MINER  Act, Illinois,  Kentucky,  Pennsylvania,  and  West  Virginia  have  enacted 
legislation  addressing  issues  such  as  mine  safety  and  accident  reporting,  increased  civil  and  criminal  penalties,  and 
increased inspections and oversight. Additionally, state administrative agencies can promulgate administrative rules and 
regulations affecting our operations. Other states may pass similar legislation or administrative regulations in the future. 

Some of the costs of complying with existing regulations and implementing new safety and health regulations may be 
passed on to our customers. Although we have not quantified the full impact, implementing and complying with these new 
federal and state safety laws and regulations have had, and are expected to continue to have, an adverse impact on our 
results of operations and financial position. 

Black Lung Benefits Act 

The BLBA requires businesses that conduct current mining operations to make payments of black lung benefits to 
current and former coal miners with black lung disease, to some survivors of a miner who dies from this disease, and to a 
trust fund for the payment of benefits and medical expenses under circumstances including where no responsible coal mine 
operator has been identified for claims. In addition, the BLBA provides that some claims for which coal operators not 
affiliated with us had previously been responsible are or will become obligations of the government trust funded by the 
excise tax referenced in this paragraph. The Federal government established such a trust fund and as of January 1, 2022, 
the trust fund was funded by an excise tax on industry-wide production of up to $0.50 per ton for underground-mined coal 
and up to $0.25 per ton for surface-mined coal, but not to exceed 2% of the applicable gross sales price. The Inflation 
Reduction Act of 2022 raised the excise tax, effective October 1, 2022, up to $1.10 per ton of coal from underground 
mines and up to $0.55 per ton of coal from surface mines, neither amount to exceed 4.4% of the gross sales price. The coal 
we sell into international markets is generally not subject to the excise tax referenced in this paragraph. The Company 
recognized expenses related to the BLBA excise tax of $30.5 million for the year ended December 31, 2023. 

Workers' Compensation and Black Lung 

We  provide  income  replacement  and  medical  treatment  for  work-related  traumatic  injury  claims  as  required  by 
applicable state laws. Workers' compensation laws also provide for the potential compensation of survivors of workers 
who suffer employment-related deaths. We generally self-insure this potential expense using our actuary estimates of the 
cost of present and future claims.  In addition, coal mining companies are subject to federal legislation and various state 
statutes for the payment of medical and disability benefits to eligible recipients related to coal worker's pneumoconiosis, 
or black lung. We also provide for these claims through self-insurance programs. The DOL's OWCP is responsible for 
authorizing coal mine operators to self-insure for federal black lung and for setting applicable security amounts. In January 
2023, the OWCP issued a Notice of Proposed Rulemaking to update its regulations authorizing coal producers to self-
insure and for determining appropriate security amounts, and announced that it plans to solicit public comments for that 
proposal. A change in requirements for security posted to self-insure black lung liabilities could result in the Company 
being required to post additional security for its obligations. Our pneumoconiosis benefits liability is calculated using the 

18 

 
 
 
 
 
 
 
service cost method based on the actuarial present value of the estimated pneumoconiosis benefits obligation. Our actuarial 
calculations are based on numerous assumptions including disability incidence, medical costs, mortality, death benefits, 
dependents, and discount rates. For more information concerning our requirement to maintain bonds to secure our workers' 
compensation obligations, see the discussion of surety bonds below under "—Bonding Requirements." 

The Patient Protection and Affordable Care Act, enacted in 2010, includes significant changes to the federal black 
lung program retroactive to 2005, including an automatic survivor benefit paid upon the death of a miner with an awarded 
black lung claim and establishes a rebuttable presumption with regard to pneumoconiosis among miners with 15 or more 
years of coal mine employment that are totally disabled by a respiratory condition. These changes have caused a significant 
increase in our costs expended in association with the federal black lung program. We may also be liable under various 
state statutes with respect to black lung claims. 

Surface Mining Control and Reclamation Act 

The  SMCRA  and  similar  state  statutes  establish  operational,  reclamation,  and  closure  standards  for  all  aspects  of 
surface  mining  as  well  as  many  aspects  of  deep  mining.  Although  we  have  minimal  surface  mining  activity  and  no 
mountaintop removal mining activity, SMCRA nevertheless requires that comprehensive environmental protection and 
reclamation standards be met during the course of and upon completion of our mining activities. 

SMCRA and similar state statutes require, among other things, that mined property be restored in accordance with 
specified standards and approved reclamation plans. SMCRA requires us to restore the surface to approximate the original 
contours as contemporaneously as practicable with the completion of surface mining operations. Federal law and some 
states impose on mine operators the responsibility for replacing certain water supplies damaged by mining operations and 
repairing  or  compensating  for  damage  to  certain  structures  occurring on  the  surface  as  a  result  of  mine  subsidence,  a 
consequence of longwall mining and possibly other mining operations. We believe we are in compliance in all material 
respects with applicable regulations relating to reclamation. We have accrued $150.4 million for the estimated costs of 
reclamation and mine closing, including the cost of treating mine water discharge when necessary. Please read "Item 8. 
Financial Statements and Supplementary Data—Note 18 – Asset Retirement Obligations." 

In addition, the Abandoned Mine Lands Program, which is part of SMCRA and relates to industry-wide operations, 
imposes a reclamation fee on all current mining operations, the proceeds of which are used to restore mines closed before 
1977. The fee expired on September 30, 2021, and was reauthorized through September 30, 2034, under the Infrastructure 
Investment  and  Jobs  Act  which  was  signed  on  November  15,  2021.  The  fee,  as  reauthorized,  for  surface-mined  and 
underground-mined coal is $0.224 per ton and $0.096 per ton, respectively, through September 30, 2034. In addition, states 
from time to time have increased and may continue to increase their fees and taxes to fund reclamation or orphaned mine 
sites and acid mine drainage control on a statewide basis.   

Under  SMCRA,  responsibility  for  unabated  violations,  unpaid  civil  penalties,  and  unpaid  reclamation  fees  of 
independent contract mine operators and other third parties can be imputed to other companies that are deemed, according 
to the regulations, to have "owned" or "controlled" the third-party violator. Sanctions against the "owner" or "controller" 
are quite severe and can include being blocked from receiving new permits and having any permits revoked that were 
issued after the time of the violations or after the time civil penalties or reclamation fees became due. We are not aware of 
any  currently pending  or  asserted  claims  against  us  relating  to  the  "ownership" or  "control"  theories  discussed  above.  
However, we cannot assure you that such claims will not be asserted in the future. 

Bonding Requirements 

Federal and state laws require bonds to secure our obligations to reclaim lands used for mining, to pay federal and 
state workers' compensation, to pay certain black lung claims, and to satisfy other miscellaneous obligations. These bonds 
are typically renewable on a yearly basis. It has become increasingly difficult for us and for our competitors to secure new 
surety bonds without posting collateral and in some cases it is unclear what level of collateral will be required. In addition, 
surety bond costs have increased while the market terms of surety bonds have generally become less favorable to us. It is 
possible that surety bond issuers may refuse to renew bonds or may demand additional collateral upon those renewals.  
Our failure to maintain or inability to acquire, surety bonds that are required by federal and state laws would have a material 
adverse effect on our ability to produce coal, which could affect our profitability and cash flow. For additional information, 
please see "Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations—Liquidity 
and Capital Resources—Cash Requirements."

Air Emissions 

The CAA and similar state and local laws and regulations regulate emissions into the air and affect coal mining, as 
well as oil & gas, operations. The CAA imposes permitting requirements and, in some cases, requirements to install certain 
emissions control equipment, achieve certain emissions standards, or implement certain work practices on sources that 
emit  various  air  pollutants.  The  CAA  also  indirectly  affects  coal  mining  operations  by  extensively  regulating  the  air 
emissions of coal-fired electric power generating plants and other coal-burning facilities. There has been a series of federal 
rulemakings focused on emissions from coal-fired electric generating facilities. Installation of additional emissions control 
technology and any additional measures required under applicable federal and state laws and regulations related to air 
emissions will make it more costly to operate coal-fired power plants and possibly other facilities that consume coal and, 
depending on the requirements of SIPs, could make fossil fuels a less attractive fuel alternative in the planning and building 
of  power plants  in  the  future.  A  significant  reduction  in  fossil  fuels'  share  of  power generating  capacity  could  have  a 
material adverse effect on our business, financial condition, and results of operations. 

In  addition  to  the  GHG  issues  discussed  below,  the  air  emissions  programs  that  may  affect  our  operations  or  the 
operations of those on the properties in which we hold mineral interests, directly or indirectly, include but are not limited 
to the following: 

•  The EPA's Acid Rain Program, provided in Title IV of the CAA, regulates emissions of sulfur dioxide from 
electric generating facilities. Sulfur dioxide is a by-product of coal combustion. Affected facilities purchase 
or are otherwise allocated sulfur dioxide emissions allowances, which must be surrendered annually in an 
amount equal to a facility's sulfur dioxide emissions in that year. Affected facilities may sell or trade excess 
allowances to other facilities that require additional allowances to offset their sulfur dioxide emissions. In 
addition to purchasing or trading for additional sulfur dioxide allowances, affected power facilities can satisfy 
the requirements of the EPA's Acid Rain Program by switching to lower-sulfur fuels, installing pollution 
control devices such as flue gas desulfurization systems, or "scrubbers," or by reducing electricity-generating 
levels. In 2023, we sold 80.9% of our total tons to electric utilities in the United States, substantially all of 
which was sold to utility plants with installed pollution control devices. These requirements would not be 
supplanted by a replacement rule for the CAIR, discussed below. 

•  The CAIR called for power plants in 28 states and Washington, D.C. to reduce emission levels of sulfur 
dioxide and nitrogen oxide pursuant to a cap-and-trade program similar to the system in effect for acid rain. 
In  June 2011,  the  EPA  finalized  the  CSAPR,  a  replacement  rule for  CAIR,  which  would  have  required 
twenty-eight states in the Midwest and eastern seaboard to reduce power plant emissions that cross state lines 
and  contribute  to  ozone  and/or  fine  particle  pollution  in  other  states.  CSAPR  has  become  increasingly 
irrelevant with continuing coal plant retirements making the nitrogen oxide ozone budget less stringent and 
lowering emission allowance prices to levels closer to average operating cost for many of our customers. The 
full impacts of CSAPR are presently unknown due to the implementation of MATS, discussed below, and 
the impact of the continuing coal plant retirements. 

• 

In May 2020, EPA issued a final rule that reversed the Agency’s prior determination from 2000 to 2016 that 
it was "appropriate and necessary" to regulate hazardous air pollutants from coal-fueled EGUs under the 
MATS rule, which regulates the emission of mercury and other metals, fine particulates, and acid gases such 
as hydrogen chloride from coal and oil-fired power plants. However, in February 2023, EPA published a 
final revocation of the May 2020 finding. Then, in April 2023, the EPA issued a proposed rule to amend the 
MATS rule, to reflect developments in control technologies and plant performance. Although the impacts of 
the potential final rule are unknown, the MATS rule has forced electric power generators to make capital 
investments to retrofit power plants and could lead to additional premature retirements of older coal-fired 
generating  units  and  many  electric  power  generators  have  already  announced  retirements  due  to  the 
uncertainty  surrounding  the MATS  rule.  The  announced and  possible  additional retirements  are  likely  to 
reduce the demand for coal. Apart from MATS, several states have enacted or proposed regulations requiring 
reductions  in  mercury  emissions  from  coal-fired  power  plants,  and  federal  legislation  to  reduce  mercury 
emissions from power plants has been proposed. Regulation of mercury emissions by the EPA, states, or 
Congress may decrease the future demand for coal. We continue to evaluate the possible scenarios associated 
with CSAPR updates and MATS and the effects they may have on our business and our results of operations, 
financial condition, or cash flows. 

20 

 
 
 
 
 
 
•  The CAA requires the EPA to periodically reevaluate the available health effects information to determine 
whether  the  NAAQS  should  be  revised.  Pursuant  to  this  process,  the  EPA  has  adopted  more  stringent 
NAAQS for fine PM, ozone, nitrogen oxide, and sulfur dioxide. As a result, some states will be required to 
amend their existing SIPs to attain and maintain compliance with the new air quality standards and other 
states will be required to develop new SIPs for areas that were previously in "attainment" but do not attain 
the new standards. In addition, under the revised ozone NAAQS, significant additional emissions control 
expenditures may be required at coal-fired power plants.  In March 2019, the EPA published a final rule that 
retained the current primary NAAQS for sulfur oxide. In December 2020, EPA published a final rule to retain 
the current NAAQS for both PM and ozone; however, various entities filed litigation against one or both of 
these rulemakings, and the Biden Administration announced that it would reconsider and potentially revise 
the  NAAQS.  With  respect  to  ozone,  a  draft  assessment  released  in  April  2022  indicated  a  preliminary 
conclusion that the December 2020 decision would stand. However, on August 21, 2023, the EPA announced 
a new review of the ozone NAAQS to reflect updated ozone science in combination with the reconsideration 
of the December 2020 decision. The Agency is expected to release its Integrated Review Plan in the fall of 
2024. New standards may impose additional emissions control requirements on new and expanded coal-fired 
power  plants  and  industrial  boilers.  Because  coal  mining  operations  and  coal-fired  electric  generating 
facilities  emit  particulate  matter  and  sulfur  dioxide,  our  mining  operations  and  our  customers  could  be 
affected when the new standards are implemented by the applicable states, and developments could indirectly 
reduce the demand for coal. Separately, the implementation of new standards by states has the potential to 
delay or otherwise impact oil & gas production activities, which could reduce the profitability of our mineral 
interests. 

•  The EPA's regional haze program is designed to protect and improve visibility at and around national parks, 
national wilderness areas, and international parks. Under the program, states are required to develop SIPs to 
improve visibility. Typically, these plans call for reductions in sulfur dioxide and nitrogen oxide emissions 
from coal-fueled electric plants. In prior cases, the EPA has decided to negate the SIPs and impose stringent 
requirements through FIPs. The regional haze program, including particularly the EPA's FIPs, and any future 
regulations  may  restrict  the  construction  of  new  coal-fired  power  plants  whose  operation  may  impair 
visibility at and around federally protected areas and may require some existing coal-fired power plants to 
install additional control measures designed to limit haze-causing emissions. These requirements could limit 
the demand for coal in some locations. In September 2018, the EPA issued a memorandum that detailed 
plans to assist states as they develop their SIPs, which was followed by a supplemental memorandum in July 
2021 for SIPs for the second implementation period. 

•  The EPA's NSR program under the CAA in certain circumstances requires existing coal-fired power plants, 
when modifications to those plants significantly increase emissions, to install more stringent air emissions 
control equipment. The Department of Justice, on behalf of the EPA, has filed lawsuits against a number of 
coal-fired electric generating facilities alleging violations of the NSR program. The EPA has alleged that 
certain modifications have been made to these facilities without first obtaining certain permits issued under 
the program. Several of these lawsuits have been settled, but others remain pending. In October 2020, the 
EPA finalized a rule to clarify the process for evaluating whether the NSR permitting program would apply 
to a proposed modification of a source of air emissions. The EPA has announced that it will review the NSR 
program. Depending on the ultimate resolution of the EPA's litigation and review, demand for coal could be 
affected. 

•  The EPA's NSPS under the CAA require the reduction of certain pollutants and methane emissions from 
certain stimulated oil & gas wells for which well completion operations are conducted and further require 
that most wells use reduced emission completions, also known as "green completions." These regulations 
also  establish  specific  new  requirements  regarding  emissions  from  production-related  wet  seal  and 
reciprocating  compressors,  and  pneumatic  controllers  and  storage  vessels.  Although  the  Trump 
Administration revised prior regulations in September 2020 to rescind certain methane standards and remove 
the transmission and storage segments from the source category for certain regulations, the U.S. Congress 
passed, and President Biden signed into law, a revocation of the 2020 rulemaking, effectively reinstating the 
2016 standards. In December 2023, EPA issued its final methane rules, known as OOOOb and OOOOc, that 
establish new source and first-time existing source standards of performance for GHG and VOC emissions 
for crude oil and natural gas well sites, natural gas gathering and boosting compressor stations, natural gas 

21 

 
 
 
 
processing  plants,  and  transmission  and  storage  facilities.  The  final  rules  include  nationwide  emissions 
guidelines for states to limit methane emissions from existing crude oil and natural gas facilities and states 
have two years to prepare and submit their plans to impose methane emission controls on existing sources. 
The rules also revise requirements for fugitive emissions monitoring and repair as well as equipment leaks 
and  the  frequency  of  monitoring  surveys  and  establishes  a  "super-emitter"  response  program  to  timely 
mitigate  emissions  events.  It  is  likely  that  the  final  rule  and  its  requirements  will  be  subject  to  legal 
challenges. Moreover, compliance with the new rules may effect the amount oil & gas companies owe under 
the Inflation Reduction Act, which amended the CAA to impose a first-time fee on the emission of methane 
from sources required to report their GHG emissions to the EPA. The methane emissions fee applies to excess 
methane emissions from certain facilities and starts at $900 per metric ton of leaked methane in 2024 and 
increases to $1,200 in 2025 and $1,500 in 2025 and thereafter. Compliance with the EPA’s new final rules 
would  exempt  an  otherwise  covered  facility  from  the  requirement  to  pay  the  methane  fee.  Oil  &  gas 
production on the properties in which we hold mineral interests could be adversely affected to the extent the 
rules and any of their requirements impose increased operating costs on the oil & gas industry. 

GHG Emissions 

Combustion of fossil fuels, such as the coal we produce and the oil & gas produced from our mineral interests, results 
in the emission of GHGs, such as carbon dioxide and methane. Combustion of fuel for mining equipment used in coal 
production also emits GHGs. Future regulation of GHG emissions in the United States could occur pursuant to future 
United  States  treaty  commitments,  new  or  existing  domestic  legislation,  or  regulation  by  the  EPA.  Although  no 
comprehensive climate change regulation has been adopted at the federal level in the United States, President Biden has 
made it clear that climate change will be a focus of his administration. For example, in January 2021, President Biden 
issued  an  executive  order  that  commits  to  substantial  action  on  climate  change,  calling  for,  among  other  things,  the 
increased use of zero-emissions vehicles by the federal government, the elimination of subsidies provided to the fossil-
fuel industry, a doubling of electricity generated by offshore wind by 2030, and increased emphasis on climate-related 
risks across governmental agencies and economic sectors. Internationally, the Paris Agreement requires member states to 
submit  non-binding,  individually  determined  emissions  reduction  targets.  These  commitments  could  further  reduce 
demand and prices for fossil fuels. President Biden recommitted the United States to the Paris Agreement in February 
2021 and, in April 2021, announced a new, more rigorous nationally determined emissions reduction level of 50-52% 
reduction from 2005 levels in economy wide net GHG emissions by 2030. The international community gathered again at 
the COP26 during which multiple announcements were made, including a call for parties to eliminate fossil fuel subsidies, 
among other measures. Relatedly, the United States and European Union jointly announced at COP26 the launch of the 
Global Methane Pledge, an initiative committing to a collective goal of reducing global methane emissions by at least 30% 
from 2020 levels by 2030, including "all feasible reductions" in the energy sector. Also at COP26, more than forty countries 
pledged to phase out coal, although the United States did not sign the pledge. In December 2023, the United Arab Emirates 
hosted the COP28 where parties signed onto an agreement to transition "away from fossil fuels in energy systems in a just, 
orderly and equitable manner" and increase renewable energy capacity so as to achieve net zero by 2050, although no 
timeline for doing so was set. The full impact of these actions remains unclear at this time. Moreover, many states, regions, 
and governmental bodies have adopted GHG initiatives and have or are considering the imposition of fees or taxes based 
on the emission of GHGs by certain facilities, including coal-fired electric generating facilities. Others have announced 
their  intent  to  increase  the  use  of renewable  energy  sources,  displacing  coal,  and  other  fossil  fuels.  Depending  on  the 
particular regulatory program that may be enacted, at either the federal or state level, the demand for coal and oil & gas 
could be negatively impacted, which would have an adverse effect on our operations. 

The  EPA  has  begun  to regulate  GHG  emissions  from  stationary  sources,  such  as  coal-fueled  power  plants,  under 
existing federal CAA. In August 2015, the EPA issued its final CPP Rule, which established carbon pollution standards 
for power plants. The CPP was subsequently challenged by multiple states and industry participants in the Court of Appeals 
for the D.C. Circuit and, in February 2016, the implementation of the CPP was stayed by the U.S. Supreme Court. Then, 
in  September  2019,  the  EPA  repealed  the  CPP  and  finalized  the  ACE  rule.  The  ACE  rule  specified  that  heat  rate 
improvement measures qualified as the BSER for existing coal-fired power plants, clarified the roles of the EPA and the 
states in the implementation of the ACE, and revised the NSR permitting program to provide EGUs the opportunity to 
make efficiency improvements without triggering NSR permit requirements. In January 2021, however, the D.C. Circuit 
vacated the ACE rule concluding that the EPA's "repeal of the CPP rested critically on a mistaken reading of the CAA." 
Although the D.C. Circuit ultimately agreed to stay its mandate, such that the CPP remained repealed, in June 2022, the 
U.S. Supreme Court in West Virginia v. EPA reversed and remanded the D.C. Circuit's decision and found that the EPA 
had acted outside the bounds of the agency’s authority in the promulgation of the CPP. Notwithstanding the litigation, the 

22 

 
 
 
CPP and the ACE led to premature retirements and could lead to additional premature retirements of coal-fired generating 
units and reduce the demand for coal. Congress has not yet adopted legislation to restrict carbon dioxide emissions from 
existing power plants and has not otherwise expanded the legal authority of the EPA following West Virginia v. EPA, but 
we cannot predict whether such legislation will be passed in the future or what the potential impacts of such legislation 
would be. 

Several rulemakings have been issued under the NSPS that constrain the GHG emissions of fossil-fuel-fired power 
plants. In October 2015, EPA published its final rule on performance standards for GHG emissions from new, modified, 
and  reconstructed  EGUs,  which  required  use  of  efficient  supercritical  pulverized  coal  boilers  that  use  partial  post-
combustion carbon capture and storage technology and imposed a new emission standard. The October 2015 rule was 
challenged by several states, industry participants and other parties in the D.C. Circuit and, in April 2017, the Court granted 
EPA’s motion to hold the litigation in abeyance while EPA reviewed the rule. Then, in December 2018, the EPA issued a 
proposed  rule  to  replace  the  October  2015  rule,  including  revising  the  BSER  for  newly  constructed  coal-fired  EGUs. 
Although the EPA has not taken further action on the December 2018 proposed rule, in May 2023, the EPA published a 
proposed  NSPS  rule  for  GHG  emissions  from new,  modified,  and  reconstructed  fossil fuel-fired  EGUs  and  emissions 
guidelines for existing fossil fuel-fired EGUs. The final rule is expected in 2024. 

There  are further  uncertainties  surrounding  the  potential  impacts  and  costs  associated  with  the  reduction  of  GHG 
emissions,  such  as:  protests  and  challenges  to  the  permitting  of  new  fossil-fuel  infrastructure  by  environmental 
organizations and state regulators; state tort liability; and state adoption of "renewable energy standards" or "renewable 
portfolio standards," which encourage or require electric utilities to obtain a certain percentage of their electric generation 
portfolio  from  renewable  resources  by  a  certain  date.  For example,  several  states  have announced  their  intent  to  have 
renewable energy comprise 100% of their electric generation portfolio and, in December 2021, President Biden issued an 
executive order setting a goal for a carbon pollution-free electricity sector across the country by 2035. To the extent these 
requirements  or  similar  requirements  that  may  be  enacted  or  adopted  in  the  future  affect  our  current  and  prospective 
customers or those of our mineral interest producers, they may reduce the demand for our coal and the oil & gas produced 
from the properties in which we hold mineral interests. For more information, see our risk factor titled "We, our customers, 
or the operators of our oil & gas mineral interests could be subject to litigation related to climate change." 

In addition, environmental advocacy groups have filed a variety of judicial challenges claiming that the environmental 
analyses conducted by federal agencies before granting permits and other approvals necessary for certain coal activities 
do  not  satisfy  the  requirements  of  the  NEPA.  These  groups  assert  that  the  environmental  analyses  in  question  do  not 
adequately consider the climate change impacts of these particular projects. In April 2022, the CEQ issued a final rule, 
considered "Phase I" of the Biden Administration’s two-phased approach to modifying the NEPA, revoking some of the 
modifications made to the NEPA regulations under the previous administration and reincorporating the consideration of 
direct,  indirect,  and  cumulative  effects  of  major  federal  actions,  including  GHG  emissions.  In  July  2023,  the  CEQ 
announced a "Phase 2" Notice of Proposed Rulemaking, the "Bipartisan Permitting Reform Implementation Rule," which 
revises the implementing regulations of the procedural provisions of NEPA and implements the amendments to NEPA 
included in the June 3, 2023, Fiscal Responsibility Act of 2023. The public comment period for the proposed rule closed 
in September 2023, and the final rule is expected in the second quarter of 2024. And, in January 2023, the CEQ released 
guidance, effective upon publication, to assist federal agencies in assessing the GHG emissions and climate change effects 
of their proposed actions under NEPA.  

Many states and regions have adopted GHG initiatives and certain governmental bodies have or are considering the 
imposition of fees or taxes based on the emission of GHG by certain facilities, including coal-fired electric generating 
facilities.  For  example,  the  RGGI  calls  for  the  implementation  of  a  cap-and-trade  program  aimed  at  reducing  carbon 
dioxide emissions from power plants in participating states. The members of RGGI have established in statutes and/or 
regulations a carbon dioxide trading program. Similar to RGGI, five western states launched the Western Regional Climate 
Initiative,  although  only  California,  Washington  and  certain  Canadian  provinces  are  currently  active  participants.  We 
cannot predict what other regional greenhouse gas reduction initiatives may arise in the future. 

It is possible that future international, federal, and state initiatives to control GHG emissions could result in increased 
costs associated with fossil-fuel production and consumption, such as costs to install additional controls to reduce carbon 
dioxide  emissions  or  costs  to  purchase  emissions  reduction  credits  to  comply  with future  emissions  trading programs.  
Such increased costs for fossil-fuel consumption could result in some customers switching to alternative sources of fuel, 
or otherwise adversely affect our operations and demand for our products, or those of the operators of our mineral interests, 
which could have a material adverse effect on our business, financial condition, and results of operations. Finally, activists 

23 

 
 
 
 
 
may  try  to  hamper  fossil-fuel  companies  by  other  means,  including  pressuring  financing  and  other  institutions  into 
restricting access to capital, bonding, and insurance, as well as pursuing tort litigation for various alleged climate-related 
impacts. For more information, see our Risk Factor titled "Our operations are subject to a series of risks resulting from 
climate change." 

Water Discharge 

The CWA and similar state and local laws and regulations regulate discharges into certain waters, primarily through 
permitting. Section 404 of the CWA imposes permitting and mitigation requirements associated with the dredging and 
filling of certain wetlands and streams. The CWA and equivalent state legislation, where such equivalent state legislation 
exists, affect coal mining operations that impact such wetlands and streams. Although permitting requirements have been 
tightened in recent years, we believe we have obtained all necessary permits required under CWA Section 404 as it has 
traditionally been interpreted by the responsible agencies. However, mitigation requirements under existing and possible 
future "fill" permits may vary considerably. For that reason, the setting of post-mine asset retirement obligation accruals 
for such mitigation projects is difficult to ascertain with certainty and may increase in the future.  For more information 
about asset retirement obligations, please read "Item 8. Financial Statements and Supplementary Data—Note 18 - Asset 
Retirement Obligations." Although more stringent permitting requirements may be imposed in the future, we are not able 
to accurately predict the impact, if any, of such permitting requirements. 

For us or the operators of the properties in which we hold oil & gas mineral interests to conduct certain activities, an 
operator may need to obtain a permit for the discharge of fill material from the Corps of Engineers and/or a discharge 
permit from the state regulatory authority under the state counterpart to the CWA. Our coal mining operations typically 
require Section 404 permits to authorize activities such as the creation of slurry ponds and stream impoundments. The 
CWA authorizes the EPA to review Section 404 permits issued by the Corps of Engineers, and in 2009, the EPA began 
reviewing Section 404 permits issued by the Corps of Engineers for coal mining in Appalachia.  Currently, significant 
uncertainty exists regarding the obtaining of permits under the CWA for coal mining operations in Appalachia due to 
various initiatives launched by the EPA regarding these permits. 

The  EPA  also  has  statutory  "veto"  power  over  a  Section  404  permit  if  the  EPA  determines,  after  notice  and  an 
opportunity for a public hearing, that the permit will have an "unacceptable adverse effect." This authority has been upheld 
by the D.C. Circuit. Any future use of the EPA's Section 404 "veto" power could create uncertainty with regard to our 
continued  use  of  current permits,  as  well  as  impose  additional  time  and  cost burdens  on  future  operations, potentially 
adversely affecting our coal revenues. In addition, the EPA initiated a preemptive veto prior to the filing of any actual 
permit application for a copper and gold mine based on a fictitious mine scenario. The implications of this decision could 
allow the EPA to bypass the state permitting process and engage in watershed and land use planning. 

States  also  have  the  ability  to  review  the  Corps  of  Engineers’  Section  404  permitting  process,  pursuant  to  CWA 
Section 401, which is also subject to ongoing litigation. In October 2021, the Northern District of California federal court 
vacated a 2020 rule revising the Section 401 certification process. The Supreme Court stayed this vacatur and, in September 
2023, the EPA finalized its Clean Water Act Section 401 Water Quality Certification Improvement Rule, effective on 
November 27, 2023. While the full extent and impact of these actions is unclear at this time, any disruption in the ability 
to obtain required permits may result in increased costs and project delays. 

TMDL  regulations  under  the  CWA  establish  a  process  to  calculate  the  maximum  amount  of  a  pollutant  that  an 
impaired waterbody can receive and still meet state water quality standards, and to allocate pollutant loads among the point 
and non-point pollutant sources discharging into that water body. Likewise, when water quality in a receiving stream is 
better than required, states are required to conduct an antidegradation review before approving discharge permits. The 
adoption of new TMDL-related allocations or any changes to antidegradation policies for streams near our coal mines 
could require more costly water treatment and could adversely affect our coal production. 

Considerable legal uncertainty exists surrounding the standard for what constitutes jurisdictional waters and wetlands 
subject to the protections and requirements of the CWA. Rulemakings to establish the extent of such jurisdiction were 
finalized in 2015 and 2020, respectively, and both rulemakings have been subject to substantial litigation. Although the 
EPA and Corps of Engineers did not seek to vacate the 2020 rule on an interim basis, two federal district courts in Arizona 
and New Mexico vacated the 2020 rule in decisions announced during the third quarter of 2021. In January 2023, the EPA 
and Corps of Engineers published a final revised definition of WOTUS founded upon a pre-2015 definition, including 
updates to incorporate existing Supreme Court decisions. However, continued uncertainty remains as to the government's 

24 

 
 
 
 
 
 
 
jurisdictional  reach  as  the  rule  is  likely  to  be  subject  to  legal  challenge.  Judicial  developments  further  add  to  this 
uncertainty. In October 2022, the Supreme Court heard oral arguments in Sackett v. EPA regarding the scope and authority 
of the CWA and the definition of WOTUS and in May 2023, issued a ruling invalidating certain parts of the January 2023 
rule, and further limiting the federal government’s jurisdiction over wetlands and tributaries. A revised WOTUS rule was 
issued in September 2023. Due to the injunction in certain states, however, the implementation of the September 2023 rule 
currently varies by state.  

Hazardous Substances and Wastes 

The CERCLA, otherwise known as the "Superfund" law, and analogous state laws, impose liability, without regard 
to fault or the legality of the original conduct on certain classes of persons that are considered to have contributed to the 
release of a "hazardous substance" into the environment. These persons include the owner or operator of the site where the 
release occurred and companies that disposed of or arranged for the disposal of the hazardous substances found at the site. 
Persons who are or were responsible for the release of hazardous substances may be subject to joint and several liability 
under CERCLA for the costs of cleaning up releases of hazardous substances and natural resource damages. Some products 
used in coal mining operations generate waste containing hazardous substances. We are currently unaware of any material 
liability associated with the release or disposal of hazardous substances from our past or present mine sites. 

The  RCRA  and  analogous  state  laws  impose  requirements  for  the  generation,  transportation,  treatment,  storage, 
disposal,  and  cleanup  of  hazardous  and  non-hazardous  wastes.  Many  mining  wastes  are excluded from  the  regulatory 
definition of hazardous wastes, and coal mining operations covered by SMCRA permits are by statute exempted from 
RCRA permitting. Similarly, most wastes associated with the exploration, development, and production of oil & gas are 
exempt from regulation as hazardous wastes under RCRA, though these wastes typically constitute "solid wastes" that are 
subject to less stringent non-hazardous waste requirements. However, it is possible that RCRA could be amended or the 
EPA  or  state  environmental  agencies  could  adopt  policies  to  require  such  wastes  to  become  subject  to more  stringent 
storage, handling, treatment, or disposal requirements, which could impose significant additional costs on the operators of 
the properties in which we own oil & gas mineral interests. RCRA also allows the EPA to require corrective action at sites 
where there is a release of hazardous substances. In addition, each state has its own laws regarding the proper management 
and disposal of waste material. While these laws impose ongoing compliance obligations, such costs are not believed to 
have a material impact on our operations. 

RCRA impacts the coal industry in particular because it regulates the disposal of certain CCB. On April 17, 2015, the 
EPA finalized regulations under RCRA for the disposal of CCB. Under the finalized regulations, CCB is regulated as 
"non-hazardous" waste and avoids the stricter, more costly, regulations under RCRA's "hazardous" waste rules. While the 
classification of CCB as a hazardous waste would have led to more stringent restrictions and higher costs, this regulation 
may still increase our customers' operating costs and potentially reduce their ability to purchase coal. The CCB rule was 
subject to legal challenge and ultimately remanded to the EPA. On August 28, 2020, the EPA published a final revised 
rule mandating the closure of unlined impoundments, with deadlines to initiate closure between 2021 and 2028, depending 
on site-specific circumstances. Certain provisions of the revised CCB rule were vacated by the D.C. Circuit in 2018. The 
EPA proposed a coal ash rule in May 2023 and the final rule is expected in April 2024. Meanwhile, on January 25, 2022, 
the EPA published determinations for 9 of 57 CCB facilities that sought approval to continue disposal of CCB and non-
CCB waste streams until 2023, as opposed to the initial 2021 deadline for unlined impoundments prescribed by the current 
rule. While the EPA issued one conditional approval, the EPA required the remaining facilities to cease receipt of waste 
within 135 days of completion of public comment, or around July 2022. And, in January 2023, the EPA issued six proposed 
determinations  to  deny  facilities'  requests  to  continue  disposal  into  unlined  surface  impoundments.  The  current 
determinations, future determinations of the same nature, or similar actions in expected future rulemakings could lead to 
accelerated, abrupt, or unplanned suspension of coal-fired boilers. The combined effect of the CCB rules and the ELG 
regulations (discussed below) has compelled power generating companies to close existing ash ponds and may force the 
closure of certain existing coal burning power plants that cannot comply with the new standards. Such retirements may 
adversely affect the demand for our coal. 

On November 3, 2015, the EPA published the final rule ELG, revising the regulations for the Steam Electric Power 
Generating category which became effective on January 4, 2016. The rule sets the first federal limits on the levels of toxic 
metals in wastewater that can be discharged from power plants, based on technological improvements in the steam electric 
power  industry  over  the  last  three  decades.  The  combined  effect  of  the  CCB  and  ELG  regulations  has  forced  power 
generating companies to close existing ash ponds and will likely force the closure of certain older existing coal-burning 
power plants that cannot comply with the new standards. In November 2019, the EPA proposed revisions to the 2015 ELG 

25 

 
 
 
 
 
rule and announced proposed changes to regulations for the disposal of coal ash in order to reduce compliance costs. In 
October  2020,  EPA  published  a  final  rule.  In  August  2021,  EPA  initiated  supplemental  rulemaking  indicating  that  it 
intended to strengthen certain discharge limits. In March 2023, the EPA proposed a rule to establish more stringent ELG 
regulations and the final rule is expected in April 2024. It is unclear what impact these regulations will have on the market 
for our products. 

Endangered Species Act 

The federal ESA and counterpart state legislation protect species threatened with possible extinction. The USFWS 
works closely with the OSM and state regulatory agencies to ensure that species subject to the ESA are protected from 
potential impacts from mining-related and oil & gas exploration and production activities. In October 2021, the Biden 
Administration  proposed  the  rollback  of  new  rules  promulgated  under  the  Trump  Administration  and  published  an 
advanced notice of proposed rulemaking to codify a general prohibition on incidental take while establishing a process to 
regulate or permit exceptions to such a prohibition. In February 2023, the USFWS published a proposed rule that revised 
the requirements for an incidental take permit application. A final rule is scheduled for release in the first quarter of 2024. 
Additionally, in June 2022, the USFWS and the National Marine Fisheries Service published a final rule rescinding the 
2020 regulatory  definition  of "habitat."  If  the  USFWS  were  to  designate  species  indigenous  to  the  areas  in  which  we 
operate as threatened or endangered or to redesignate a species from threatened to endangered, we or the operators of the 
properties  in  which  we  hold  oil  &  gas  mineral  interests  could  be  subject  to  additional  regulatory  and  permitting 
requirements, which in turn could increase operating costs or adversely affect our revenues.  

Other Environmental, Health, and Safety Regulations 

In addition to the laws and regulations described above, we are subject to regulations regarding underground and 
above-ground storage tanks in which we may store petroleum or other substances. Some monitoring equipment that we 
use is subject to licensing under the Federal Atomic Energy Act. Water supply wells located on our properties are subject 
to federal, state, and local regulations. In addition, our use of explosives is subject to the Federal Safe Explosives Act. We 
are  also  required  to  comply  with  the  Federal  Safe  Drinking  Water  Act,  the  Toxic  Substance  Control  Act,  and  the 
Emergency Planning and Community Right-to-Know Act. The costs of compliance with these regulations should not have 
a material adverse effect on our business, financial condition, or results of operations. 

Human Capital 

To  conduct  our  operations,  as  of  December  31,  2023,  we  employed  3,595  full-time  employees,  including  3,038 
employees involved in active coal mining operations, 408 employees in other operations, and 193 corporate employees. 
In  2023  we  reviewed  the  work  duties  of  our  employees  and  reclassified  68  of  our  technical  services  employees  from 
corporate  employees  to  employees  involved  in  other  operations.  Our  workforce  is  entirely  union-free.  Our  typical 
employee has approximately six years of experience with the Partnership and more than 40% of all employees remain 
employed for more than five years.   

To  attract  and  retain  the  most  qualified  personnel  across  all  functions  of  our  business  we  offer  competitive 
compensation packages. In making decisions regarding employee compensation, we review current compensation levels 
for  each  position  within  other  companies  in  the  coal  industry  and  other  peers  and  use  our  discretion  to  determine  an 
appropriate  total  compensation  package,  which  generally  includes  some  combination  of  base  salary,  incentive 
compensation, health and welfare benefits and participation in our profit sharing and savings plan.  Depending on the 
position and employer, incentive compensation bonuses can be based on production and safety goals at a specific coal 
operation or broader performance goals across the Partnership, among other factors. We intend for each employee's total 
compensation to be competitive in the marketplace.   

Workplace safety is fundamental to our culture. By providing a work environment that rewards safety and encourages 
employee participation in the safety process, we have a demonstrated history as a leader in safety performance in the coal 
mining industry. We are focused on improving employee safety through regular training and continuous monitoring of our 
progress  through  various  industry-standard  metrics.  In  addition,  we  collected  approximately  13,800  respirable  dust 
samples from the mining environment where our miners regularly work and travel. The average concentration of those 
samples was 56% below the regulatory standard. We are also regularly inspected by MSHA. For more information about 
citations or orders for violations of standards under the FMSHA, as amended by the MINER Act, please see our Exhibit 
95.1 to this Annual Report on Form 10-K.  

26 

 
 
 
 
 
 
 
 
We are focused on the health of our employees. In addition to providing medical, dental, and vision benefits for our 
employees,  we  also  provide  on-site  medical  clinics  to  provide  medical  services  to  our  employees  and  their  families. 
Furthermore, at each of our coal operations and corporate offices, we provide a human resource representative to assist 
employees with various human resource matters. The Partnership also administers our medical plan, which allows us to 
control costs and work directly on behalf of our employees with healthcare providers.  To date, we have been able to 
continue providing health and welfare benefits with no out-of-pocket premiums for our employees and 100% coverage 
with direct contract providers.

Tax Risks to Our Common Unitholders 
•  Our tax treatment depends on our status as a partnership for U.S. federal income tax purposes, and not being 
subject to a material amount of entity-level taxation. Our cash available for distribution to unitholders may be 
substantially  reduced  if  we  become  subject  to  entity-level  taxation  as  a  result  of  the  IRS  treating  us  as  a 
corporation or legislative, judicial, or administrative changes, and may also be reduced by any audit adjustments 
if imposed directly on the Partnership. 

•  Even if unitholders do not receive any cash distributions from us, unitholders will be required to pay taxes on 
their share of our taxable income. A unitholder's share of our taxable income may be increased as a result of the 
IRS successfully contesting any of the federal income tax positions we take. 

•  Tax gain or loss on the disposition of our units could be more than expected and create tax liabilities for our 

unitholders 

•  Limitation on unitholders' ability to deduct interest expense incurred by us could create tax liabilities for our 

unitholders 

•  Tax Exempt entities and non-U.S. unitholders face unique tax issues from owning our common units that may 

• 
• 

result in adverse tax consequences for them 
IRS challenging our allocation of depreciation and amortization deductions could cause adverse tax consequences 
IRS  challenging  methods  of  prorating  items  of  income,  gain,  loss,  and  deduction  could  cause  adverse  tax 
consequences 

•  Unitholders with units subject to securities loans could face adverse tax consequences 
•  Certain U.S. federal income tax deductions currently available with respect to coal mining and production may 

be eliminated as a result of future legislation 

•  Unitholders could be subject to state and local taxes and income tax return filing due to their status as a unitholder 

29 

 
 
Risks Inherent in an Investment in Us 

Cash distributions to unitholders are not guaranteed. 

The payment and amount of any future distribution will be subject to the sole discretion of the Board of Directors and 
will depend upon many factors, including our financial condition and prospects, our capital requirements and access to 
financing, covenants associated with our debt obligations, and other factors that our Board of Directors may deem relevant, 
and there can be no assurance that we will pay a distribution in the future. The amount of cash we can distribute to holders 
of our common units or other partnership securities each quarter principally depends on the amount of cash we generate 
from  our  operations,  which  fluctuates  from  quarter  to  quarter.    In  addition,  the  actual  amount  of  cash  available  for 
distribution may depend on other factors, including capital allocation decisions, financing availability, restrictions in debt 
agreements, and the amount of cash reserves, if any, established by the general partner, in its discretion, for the proper 
conduct of our business.  

Furthermore, since the amount of cash we have available for distribution is not solely a function of profitability, which 
will be affected by non-cash items, we may make cash distributions during periods when we record net losses and may be 
unable  to  make  cash  distributions  during  periods  when  we  record  net  income.  Please  read  "—Risks  Related  to  our 
Business" for a discussion of further risks affecting our ability to generate available cash. 

We may issue an unlimited number of limited partner interests, on terms and conditions established by our general 
partner, without the consent of our unitholders, which will dilute your ownership interest in us and could increase the 
risk that we will not have sufficient available cash to make distributions. 

The issuance by us of additional common units or other equity securities of equal or senior rank will have the following 

effects: 

• 
• 
• 
• 
• 

our unitholders' proportionate ownership interest in us will decrease; 
the amount of cash available for distribution on each unit could decrease; 
the relative voting strength of each previously outstanding unit could be diminished; 
the ratio of taxable income to distributions could increase; and 
the market price of our common units could decline. 

The market price of our common units could be adversely affected by sales of substantial amounts of our common 

units in the public markets, including sales by our existing unitholders. 

The sale or disposition of a substantial number of our common units by our existing unitholders in the public markets 
could have a material adverse effect on the price of our common units or could impair our ability to obtain capital through 
an offering of equity securities. We do not know whether any such sales would be made in the public market or private 
placements, nor do we know what impact such potential or actual sales would have on our unit price in the future. 

An increase in interest rates could cause the market price of our common units to decline. 

Like all equity investments, an investment in our common units is subject to certain risks. In exchange for accepting 
these risks, investors may expect to receive a higher rate of return than would otherwise be obtainable from lower-risk 
investments. Accordingly, as interest rates rise, the ability of investors to obtain higher risk-adjusted rates of return by 
purchasing  government-backed  debt  securities  could  cause  a  corresponding  decline  in  demand  for  riskier  investments 
generally, including yield-based equity investments such as publicly traded limited partnership interests.  Reduced demand 
for our common units resulting from investors seeking other more favorable investment opportunities could cause the 
trading price of our common units to decline. 

The  credit  and  risk  profile  of  our  general  partner  and  its  owners  could  adversely  affect  our  credit  ratings  and 

profile. 

The credit and risk profile of our general partner or its owners may be factors in credit evaluations of us as a master 
limited partnership. This is because our general partner can exercise significant influence or control over our business 
activities, including our cash distribution policy, acquisition strategy, and business risk profile. 

30 

 
 
 
 
 
 
 
 
 
 
 
 
 
Our unitholders do not elect our general partner or vote on our general partner's officers or directors.   

Unlike  the  holders  of  common  stock  in  a  corporation,  our  unitholders  have  only  limited  voting  rights  on  matters 
affecting  our  business  and,  therefore,  limited  ability  to  influence  management's  decisions  regarding  our  business.  
Unitholders  did  not  elect  our  general  partner  and  will  have  no  right  to  elect  our  general  partner  on  annual  or  other 
continuing bases. If our unitholders are dissatisfied with the performance of our general partner, they will have little ability 
to remove our general partner. Our general partner may not be removed except upon the vote of the holders of at least 
66.7% of our outstanding units.   

Our unitholders' voting rights are also restricted by a provision in our partnership agreement that provides that any 
units held by a person that owns 20.0% or more of any class of units then outstanding, other than our general partner and 
its affiliates, cannot be voted on any matter. 

The control of our general partner may be transferred to a third party without unitholder consent. 

Our general partner may transfer its general partner interest in us to a third party in a merger or a sale of its equity 
securities without the consent of our unitholders. Furthermore, there is no restriction in the partnership agreement on the 
ability of the members of our general partner to sell or transfer all or part of their ownership interest in our general partner 
to a third party. The new owner or owners of our general partner would then be in a position to replace the directors and 
officers of our general partner and control the decisions made and actions taken by the Board of Directors and officers. 

Unitholders may be required to sell their units to our general partner at an undesirable time or price. 

If at any time less than 20.0% of our outstanding common units are held by persons other than our general partner and 
its affiliates, our general partner will have the right to acquire all, but not less than all, of those units at a price no less than 
their then-current market price. As a consequence, a unitholder may be required to sell his common units at an undesirable 
time or price. Our general partner may assign this purchase right to any of its affiliates or us. 

Cost  reimbursements  due  to  our  general  partner  could  be  substantial  and  could  reduce  our  ability  to  pay 

distributions to unitholders. 

Before making any distributions to our unitholders, we will reimburse our general partner and its affiliates for all 
expenses they have incurred on our behalf. The reimbursement of these expenses and the payment of these fees could 
adversely affect our ability to make distributions to the unitholders. Our general partner has sole discretion to determine 
the amount of these expenses and fees. For additional information, please see "Item 13. Certain Relationships and Related 
Transactions, and Director Independence—Related-Party Transactions—Administrative Services."  

Your liability as a limited partner may not be limited, and our unitholders could have to repay distributions or make 

additional contributions to us under certain circumstances. 

As a limited partner in a partnership organized under Delaware law, you could be held liable for our obligations to the 
same  extent  as  a  general  partner  if  you  participate  in  the  "control"  of  our  business.  Our  general  partner  generally has 
unlimited liability for the obligations of the partnership, except for those contractual obligations of the partnership that are 
expressly made without recourse to our general partner. Additionally, the limitations on the liability of holders of limited 
partner interests for the obligations of a limited partnership have not been established in many jurisdictions. 

Under  certain  circumstances, our  unitholders  could  have  to  repay  amounts  wrongfully  distributed  to  them.  Under 
Delaware law, we may not make a distribution to our unitholders if the distribution would cause our liabilities to exceed 
the fair value of our assets. Delaware law provides that for three years from the date of the impermissible distribution, 
partners who received the distribution and who knew at the time of the distribution that it violated Delaware law will be 
liable to the partnership for the distribution amount. Liabilities to partners on account of their partnership interest and 
liabilities that are non-recourse to the partnership are not counted for purposes of determining whether a distribution is 
permitted.

Our  partnership  agreement  limits  our  general  partner's  fiduciary  duties  to  our  unitholders  and  restricts  the 
remedies available to unitholders for actions taken by our general partner that may otherwise constitute breaches of 
fiduciary duty. 

Our partnership agreement contains provisions that waive or consent to conduct by our general partner and its affiliates 
and  which  reduce  the  obligations  to  which  our  general  partner  would  otherwise  be  held  by  state-law  fiduciary  duty 
standards. The following is a summary of the material restrictions contained in our partnership agreement on the fiduciary 
duties owed by our general partner to the limited partners. Our partnership agreement: 

• 

• 
• 

• 

permits our general partner to make many decisions in its "sole discretion." This entitles our general partner to 
consider only the interests and factors that it desires, and it has no duty or obligation to give any consideration to 
any interest of, or factors affecting us, our affiliates, or any limited partner; 
provides that our general partner is entitled to make other decisions in its "reasonable discretion"; 
generally provides that affiliated transactions and resolutions of conflicts of interest not involving a required vote 
of unitholders must be "fair and reasonable" to us and that, in determining whether a transaction or resolution is 
"fair and reasonable," our general partner may consider the interests of all parties involved, including its own. 
Unless our general partner has acted in bad faith, the action taken by our general partner shall not constitute a 
breach of its fiduciary duty; and 
provides that our general partner and our officers and directors will not be liable for monetary damages to us, our 
limited partners, or assignees for errors of judgment or any acts or omissions if our general partner and those 
other persons acted in good faith. 

All  limited  partners  are  bound  by  the  provisions  in  the  partnership  agreement,  including  the  provisions  discussed 

above. 

Our general partner's discretion in determining the level of cash reserves may adversely affect our ability to make 

cash distributions to our unitholders. 

Our partnership agreement requires our general partner to deduct from available cash reserves that in its reasonable 
discretion are necessary for the proper conduct of our business, to comply with applicable law or agreements to which we 
are a party, or to provide funds for future distributions to partners. These cash reserves will affect the amount of cash 
available for distribution to unitholders. 

Our general partner has conflicts of interest and limited fiduciary responsibilities, which may permit our general 

partner to favor its interests to the detriment of our unitholders. 

Conflicts of interest could arise in the future as a result of relationships between our general partner and its affiliates, 
on the one hand, and us, on the other hand. As a result of these conflicts, our general partner may favor its interests and 
those  of  its  affiliates  over  the  interests  of  our  unitholders.  The  nature  of  these  conflicts  includes  the  following 
considerations: 

•  Remedies  available  to  our  unitholders  for  actions  that,  without  the  limitations,  could  constitute  breaches  of 
fiduciary duty are limited. Unitholders are deemed to have consented to some actions and conflicts of interest 
that could otherwise be deemed a breach of fiduciary or other duties under applicable state law. 

•  Our general partner is allowed to take into account the interests of parties in addition to us in resolving conflicts 

of interest, thereby limiting its fiduciary duties to our unitholders. 

•  Our general partner's affiliates are not prohibited from engaging in other businesses or activities, including those 
in  direct  competition  with  us,  except  as  provided  in  the  omnibus  agreement  (please  see  "Item  13.  Certain 
Relationships and Related Transactions, and Director Independence—Omnibus Agreement"). 

•  Our general partner determines the amount and timing of our asset purchases and sales, capital expenditures, 

borrowings, and reserves, each of which can affect the amount of cash that is distributed to unitholders. 

•  Our general partner determines whether to issue additional units or other equity securities in us. 
•  Our general partner determines which costs are reimbursable by us. 
•  Our general partner controls the enforcement of obligations owed to us by it. 
•  Our general partner decides whether to retain separate counsel, accountants, or others to perform services for us. 

32 

 
 
 
 
 
 
 
 
•  Our general partner is not restricted from causing us to pay it or its affiliates for any services rendered on terms 
that are fair and reasonable to us or from entering into additional contractual arrangements with any of these 
entities on our behalf. 
In some instances, our general partner may direct us to borrow funds to permit the payment of distributions. 

• 

Some of our executive officers and directors face potential conflicts of interest in managing our business. 

Certain of our executive officers and directors are also officers and/or directors of AGP. These relationships could 
create conflicts of interest regarding corporate opportunities and other matters. The resolution of any such conflicts may 
not always be in our or our unitholders' best interests. These officers and directors face potential conflicts regarding the 
allocation of their time, which could adversely affect our business, results of operations, and financial condition. 

Increasing attention to ESG matters may negatively impact our business, financial results, and unit price. 

Companies  across  all  industries,  including  companies  in  fossil-fuel  industries,  are  facing  increased  scrutiny  from 
stakeholders related to their ESG practices. Companies that do not adapt or comply with evolving investor or stakeholder 
expectations and standards, or are perceived to have not responded appropriately to ESG issues, regardless of any legal 
requirement  to  do  so,  may  suffer  reputational  damage  and  the  business,  financial  condition,  and  valuation  of  such 
companies could be materially and adversely affected. Several advocacy groups, both domestically and internationally, 
have campaigned for governmental and private action to promote change at public companies related to ESG matters, 
including through the investment and voting practices of investment advisers, public pension funds, universities, and other 
members of the investing community. These activities include increasing attention to and demands for action related to 
climate change, promoting the use of substitutes to fossil-fuel products, encouraging the divestment of fossil-fuel equities, 
and pressuring lenders to limit funding to companies engaged in the extraction of fossil-fuel reserves. These activities 
could increase costs, reduce demand for our coal and hydrocarbon products, reduce our profits, increase the potential for 
investigations and litigation, impair our brand, limit our choices for lenders, insurance providers and business partners, 
and have negative impacts on our unit price and access to capital markets.  

In addition, certain organizations that provide corporate governance and other corporate risk information to investors 
and  unitholders  have  developed  scores  and  ratings  to  evaluate  companies  and  investment  funds  based  on  ESG  or 
"sustainability"  metrics.  Currently,  there  are  no  universal  standards  for  such  scores  or  ratings,  but  consideration  of 
sustainability  evaluations  is  becoming  more  broadly  accepted  by  investors.  Indeed,  many  investment  funds  focus  on 
positive ESG business practices and sustainability scores when making investments, whereas other funds may use certain 
ESG criteria to "screen" certain sectors, such as coal or fossil fuels more generally, out of their investments. In addition, 
investors, particularly institutional investors, use these scores to benchmark companies against their peers and if a company 
is perceived as lagging, these investors may engage with companies to require improved ESG disclosure or performance 
or sell their interests in the company, particularly if its ESG performance does not improve. Moreover, certain members 
of the broader investment community may consider a company's sustainability score as a reputational or other factor in 
making an investment decision. Companies in the energy industry, and in particular those focused on coal, natural gas, or 
oil extraction, often do not score as well under ESG assessments compared to companies in other industries.  Consequently, 
a low ESG or sustainability score could result in our securities, both debt and equity, being excluded from the portfolios 
of certain investment funds and investors, restricting our access to capital to fund our continuing operations and growth 
opportunities. Additionally, to the extent ESG matters negatively impact our reputation, we may not be able to compete as 
effectively to recruit or retain employees, which may adversely affect our operations. 

Public statements with respect to ESG matters, such as emission reduction goals, other environmental targets, or other 
commitments addressing certain social issues, are becoming increasingly subject to heightened scrutiny from public and 
governmental  authorities  related  to  the  risk  of  potential  "greenwashing,"  i.e.,  misleading  information  or  false  claims 
overstating potential ESG benefits. For example, in March 2021, the SEC established the Climate and ESG Task Force in 
the Division of Enforcement to identify and address potential ESG-related misconduct, including greenwashing. Certain 
non-governmental organizations and other private actors have also filed lawsuits under various securities and consumer 
protection  laws  alleging  that  certain  ESG-statements,  emission  reduction  claims,  approaches  to  accounting  for  GHG 
emissions reductions, or other ESG-related goals, or standards were misleading, false, or otherwise deceptive. As a result, 
we may face increased litigation risks from private parties and governmental authorities related to our ESG efforts. In 
addition, any alleged claims of greenwashing against us or others in our industry may lead to further negative sentiment 
and diversion of investments. Additionally, we could face increasing costs as we attempt to comply with and navigate 
further ESG-related focus and scrutiny.

Risks Related to our Business 

Global economic conditions or economic conditions in any of the industries in which our customers operate as 
well as sustained uncertainty in financial markets could have material adverse impacts on our business and financial 
condition that we currently cannot predict. 

Weakness in global economic conditions or economic conditions in any of the industries we serve or in the financial 

markets could materially adversely affect our business and financial condition. For example: 

• 

• 

• 

the demand for electricity in the United States and globally could  decline if economic conditions deteriorate, 
which could negatively impact the revenues, margins, and profitability of our business; 
any inability of our customers to raise capital could adversely affect their ability to honor their obligations to us; 
and 
our future ability to access the capital markets could be restricted as a result of future economic conditions, which 
could materially impact our ability to grow our business, including the development of our coal mineral reserves 
and resources. 

We face various risks related to pandemics and similar outbreaks, which have had and may in the future have 

material adverse effects on our business, financial position, results of operations, and/or cash flows. 

Pandemics,  outbreaks  or  other  public  health  events  that  are  outside  of  our  control  could  significantly  disrupt  our 
operations and adversely affect our financial condition. The global or national outbreak of an illness or other communicable 
disease, or  any other public health crisis, such as COVID-19, may cause disruptions to our business and operations, which 
may include (i)  shortages of employees, (ii) unavailability of contractors or subcontractors, (iii) interruption of supplies 
from third parties upon which we rely, (iv) restrictions recommended or imposed by government and health authorities, 
including quarantines,  to address an outbreak and (v) restrictions that we and our contractors, subcontractors and our 
customers impose, including  facility shutdowns, to ensure the safety of employees. 

The extent to which COVID-19 or another future pandemic may adversely impact our results of operations, cash flows 

and financial condition depends on future developments, which are highly uncertain and unpredictable.  

Growing our business could require significant amounts of financing that may not be available to us on acceptable 

terms, or at all. 

We plan to fund capital expenditures for our growth initiatives with existing cash balances, future cash flows from 
operations, borrowings under revolving credit and securitization facilities, and cash provided from the issuance of debt or 
equity. At times, weakness in the energy sector in general and coal, in particular, has significantly impacted access to the 
debt and equity capital markets. Accordingly, our funding plans could be negatively impacted by constraints in the capital 
markets as well as numerous other factors, including higher than anticipated capital expenditures or lower than expected 
cash flow from operations. In addition, we could be unable to refinance our current debt obligations when they expire or 
obtain adequate funding prior to expiry because our lending counterparties may be unwilling or unable to meet our funding 
needs. Furthermore, additional growth projects and expansion opportunities could develop in the future that could also 
require significant amounts of financing that may not be available to us on acceptable terms or in the amounts we expect, 
or at all. 

Various factors could adversely impact the debt and equity capital markets as well as our credit ratings or our ability 
to remain in compliance with the financial covenants under our then-current debt agreements, which in turn could have a 
material adverse effect on our financial condition, results of operations, and cash flows. If we are unable to finance our 
growth initiatives as expected, we could be required to seek alternative financing, the terms of which may not be attractive 
to us, or to revise or cancel our plans. 

34 

 
 
 
 
 
 
 
 
 
 
 
 
Our indebtedness could limit our ability to borrow additional funds, make distributions to unitholders, or capitalize 

on business opportunities. 

We had long-term indebtedness of $347.6 million as of December 31, 2023. Our leverage may: 

adversely affect our ability to finance future operations and capital needs; 
limit our ability to pursue acquisitions and other business opportunities; 

• 
• 
•  make our results of operations more susceptible to adverse economic or operating conditions; and 
•  make it more difficult to self-insure for our workers' compensation obligations. 

In addition, we have unused borrowing capacity under our revolving credit facility. Future borrowings, under our 

credit facilities or otherwise, could increase our leverage. 

Our payments of principal and interest on any indebtedness will reduce the cash available for distribution on our units. 

We will be prohibited from making cash distributions: 

• 
• 

during an event of default under any of our indebtedness; or 
if after such distribution, we fail to meet a coverage test based on the ratio of our consolidated cash flow to our 
consolidated fixed charges. 

Various limitations in our debt agreements may reduce our ability to incur additional indebtedness, engage in some 
transactions, and capitalize on business opportunities. Any subsequent refinancing of our current indebtedness or any new 
indebtedness could have similar or greater restrictions. Please see "Item 8. Financial Statements and Supplementary Data—
Note 6 – Long-Term Debt" for further discussion. 

We depend on the leadership and involvement of Joseph W. Craft III and other key personnel for the success of 

our business. 

We depend on the leadership and involvement of Mr. Craft. Mr. Craft has been integral to our success, due in part to 
his ability to identify and develop internal growth projects and accretive acquisitions, make strategic decisions, and attract 
and  retain  key  personnel.  The  loss  of  his  leadership  and  involvement  or  the  services  of  any  members  of  our  senior 
management team could have a material adverse effect on our business, financial condition, and results of operations. 

We and our subsidiaries are subject to various legal proceedings, which could have a material adverse effect on 

our business. 

We are party to a number of legal proceedings incident to our normal business activities. There is the potential that an 
individual  matter  or  the  aggregation  of  multiple  matters  could  have  an  adverse  effect  on  our  cash  flows,  results  of 
operations,  or  financial  position.  Please  see  "Item  3.  Legal  Proceedings"  and  "Item  8.  Financial  Statements  and 
Supplementary Data—Note 21 – Commitments and Contingencies" for further discussion. 

The stability and profitability of our operations could be adversely affected if our customers do not honor existing 

contracts or do not extend existing or enter into new long-term contracts for coal. 

In 2023, we sold approximately 93.4% of our coal sales tonnage under contracts having a term greater than one year, 
which we refer to as long-term sales contracts. These contracts have historically provided a relatively secure market for 
the production committed under the terms of the contracts. From time to time industry conditions could make it more 
difficult for us to enter into long-term sales contracts with our electric utility customers, and if supply exceeds demand in 
the coal industry, electric utilities may become less willing to lock in price or quantity commitments for an extended period 
of time. Accordingly, we may not be able to continue to obtain long-term sales contracts with reliable customers as existing 
contracts expire, which could subject a portion of our revenue stream to the increased volatility of the spot market. 

Some of our long-term sales contracts contain provisions allowing for the renegotiation of prices and, in some 

instances, the termination of the contract or the suspension of purchases by customers. 

Some of our long-term sales contracts contain provisions that allow the purchase price to be renegotiated at periodic 
intervals. These price reopener provisions may automatically set a new price based on the prevailing market price or, in 

35 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
some instances, require the parties to the contract to agree on a new price. Any adjustment or renegotiation leading to a 
significantly  lower  contract  price  could  adversely  affect  our  operating  profit  margins.  Accordingly,  long-term  sales 
contracts may provide only limited protection during adverse market conditions. In some circumstances, the failure of the 
parties to agree on a price under a reopener provision can also lead to the early termination of a contract. 

Several  of  our  long-term  sales  contracts  also  contain  provisions  that  allow  the  customer  to  suspend  or  terminate 
performance  under  the  contract  upon  the  occurrence  or  continuation  of  certain  events  that  are  beyond  the  customer's 
reasonable  control.  Such  events  could  include  labor  disputes,  mechanical  malfunctions,  and  changes  in  government 
regulations, including changes in environmental regulations rendering the use of our coal inconsistent with the customer's 
environmental compliance strategies. Additionally, most of our long-term sales contracts contain provisions requiring us 
to  deliver  coal  within  stated  ranges  for  specific  coal  characteristics.  Failure  to  meet  these  specifications  can  result  in 
economic penalties, rejection or suspension of shipments, or termination of the contracts. In the event of early termination 
of any of our long-term sales contracts, if we are unable to enter into new contracts on similar terms, our business, financial 
condition, and results of operations could be adversely affected. 

We depend on a few customers for a significant portion of our revenues, and the loss of one or more significant 

customers could affect our ability to maintain the sales volume and price of the coal we produce. 

In 2023, we derived more than 10% of our total revenues from each of American Electric Power and Tennessee Valley 
Authority. If we were to lose this or any of our significant customers without finding replacement customers willing to 
purchase  an  equivalent  amount  of  coal  on  similar  terms,  or  if  these  customers  were  to  decrease  the  amounts  of  coal 
purchased or change the terms, including pricing terms, on which they buy coal from us, it could have a material adverse 
effect on our business, financial condition, and results of operations. 

Our ability to collect payments from our customers could be impaired if their creditworthiness declines or if they 

fail to honor their contracts with us. 

Our ability to receive payment for coal sold and delivered depends on the continued creditworthiness of our customers. 
If the creditworthiness of our customers declines significantly, our business could be adversely affected. In addition, if a 
customer refuses to accept shipments of our coal for which they have an existing contractual obligation, our revenues will 
decrease and we may have to reduce production at our mines until our customer's contractual obligations are honored.   

Terrorist attacks or cyber incidents could result in information theft, data corruption, operational disruption, 

and/or financial loss.  

Like  most  companies,  we  have  become  increasingly  dependent  upon  digital  technologies,  including  information 
systems, infrastructure, and cloud applications and services, to operate our businesses, process and record financial and 
operating data, communicate with our business partners, analyze mine and mining information, and estimate quantities of 
reserves and resources, as well as other activities related to our businesses. Strategic targets, such as energy-related assets, 
could be at greater risk of future terrorist or cyber-attacks than other targets in the United States. Deliberate attacks on, or 
security breaches in, our systems or infrastructure, or the systems or infrastructure of third parties could lead to corruption 
or loss of our proprietary data and potentially sensitive data, delays in production or delivery, difficulty in completing and 
settling transactions, misdirected wire transfers, challenges in maintaining our books and records, environmental damage, 
communication interruptions, other operational disruptions, and third-party liability. Our insurance may not protect us 
against such occurrences. Consequently, it is possible that any of these occurrences, or a combination of them, could have 
a material adverse effect on our business, financial condition, results of operations, cash flows and reputation. Further, as 
cyber incidents continue to evolve, we could be required to expend additional resources to continue to modify or enhance 
our protective measures or to investigate and remediate any vulnerability to cyber incidents. 

Although none of our employees are members of unions, our workforce may not remain union-free in the future. 

None of our employees are represented under collective bargaining agreements. However, our workforce may not 
remain union-free in the future, and legislative, regulatory, or other governmental action could make it more difficult to 
remain union-free. If some or all of our currently union-free operations were to become unionized, it could adversely affect 
our productivity and increase the risk of work stoppages at our mining complexes. In addition, even if we remain union-
free,  our  operations  could  still  be  adversely  affected  by  work  stoppages at  unionized  companies,  particularly  if  union 
workers were to orchestrate boycotts against our operations.

Risks Related to Our Industries 

Prices for oil & gas, as well as coal, are volatile and can fluctuate widely based on a number of factors beyond our 

control.  An extended decline in the prices of such commodities could negatively impact our results of operations. 

Our  results  of operations  are primarily  dependent  upon  the  prices  of  oil  &  gas  and  coal,  as  well  as  our  ability  to 
improve  productivity  and  control  costs.  The  prices  for  oil  &  gas  and  coal  depend  upon  factors  beyond  our  control, 
including: 

overall domestic and global economic conditions; 
the supply of and demand for domestic and foreign coal; 
the supply of and demand for oil & gas; 

• 
• 
• 
•  weather conditions and patterns that affect demand for coal and oil & gas, or our ability to produce coal or the 

ability of operators to produce oil & gas from our mineral interests; 
supply chain and cost of raw materials for coal and oil & gas operations; 
the adverse impact of pandemics, outbreaks and other public health events; 
the proximity to and capacity of transportation facilities; 
competition from other coal suppliers; 
domestic and foreign governmental regulations and taxes; 
the price and availability of alternative fuels; 
the  effect  of  worldwide  energy  consumption,  including  the  impact  of  technological  advances  on  energy 
consumption; 
international developments impacting the supply of coal; 
international developments impacting the supply of oil & gas; and 
the impact of domestic and foreign governmental laws and regulations. 

• 
• 
• 
• 
• 
• 
• 

• 
• 
• 

Any adverse change in these factors could result in weaker demand and lower prices for our products. A substantial 
or extended decline in coal prices could materially and adversely affect us by decreasing our revenues to the extent we are 
not protected by the terms of existing coal supply agreements. 

Competition within the coal industry could adversely affect our ability to sell coal. In addition, foreign currency 

fluctuations could adversely affect the competitiveness of our coal abroad. 

We compete with other coal producers in various regions of the United States for domestic coal sales. In addition, we 
face  competition  from  foreign  and  domestic  producers  that  sell  their  coal  in  the  international  coal  markets.  The  most 
important  factors  on  which  we  compete  are  delivered  price  (i.e.,  the  cost  of  coal  delivered  to  the  customer,  including 
transportation costs, which are generally paid by our customers either directly or indirectly), coal quality characteristics, 
contract flexibility (e.g., volume optionality and multiple supply sources), and reliability of supply. Some competitors 
could have, among other things, larger financial and operating resources, lower per ton cost of production, or relationships 
with specific transportation providers. The competition among coal producers could impact our ability to retain or attract 
customers and could adversely impact our revenues and cash available for distribution. 

We  sell  coal  in  the  export  thermal  and  metallurgical  coal  market,  both  of  which  are  significantly  affected  by 
international demand and competition. Consolidation in the coal industry or current or future bankruptcy proceedings of 
coal competitors could adversely affect us. The prices of and demand for our coal could significantly decline, which could 
have a material adverse effect on our business, financial condition, results of operations, and cash flows, and could reduce 
our revenues and cash available for distribution. 

In addition, we face competition from foreign producers that sell their coal in the export market. Potential changes to 
international  trade  agreements,  trade  concessions,  or  other  political  and  economic  arrangements  could  benefit  coal 
producers operating in countries other than the United States. We could be adversely impacted on the basis of price or 
other  factors  by  foreign  trade  policies  or  other  arrangements  that  benefit  competitors.  In  addition,  coal  is  sold 
internationally in United States dollars and, as a result, general economic conditions in foreign markets and changes in 
foreign currency exchange rates could provide our foreign competitors with a competitive advantage. If our competitors' 
currencies decline against the United States dollar or foreign purchasers' local currencies, those competitors could be able 

37 

 
 
 
 
 
 
 
 
 
to offer lower prices for coal to those purchasers. Furthermore, if the currencies of overseas purchasers were to significantly 
decline in value in comparison to the United States dollar, those purchasers may seek decreased prices for the coal we sell. 
Consequently, currency fluctuations could adversely affect the competitiveness of our coal in international markets, which 
could have a material adverse effect on our business, financial condition, results of operations, and cash flows. 

Changes in taxes or tariffs and other trade measures by the United States and foreign governments could adversely 

affect our results of operations, financial position, and cash flows. 

We pay certain taxes and fees related to our operations. Congress or state legislatures may seek to increase these taxes 
and fees that relate specifically to the coal industry. We cannot predict further developments, and such increases could 
have a material adverse effect on our results of operations, financial position, and cash flows. 

New tariffs and other trade measures could adversely affect our results of operations, financial position, and cash 
flows. In response to tariffs imposed by the United States, the European Union, Canada, Mexico, and China have imposed 
tariffs on United States goods and services. The new tariffs, along with any additional tariffs or trade restrictions that may 
be implemented by the United States or retaliatory trade measures or tariffs implemented by other countries, could result 
in  reduced  economic  activity,  increased  costs  in  operating  our  business,  reduced  demand  and  changes  in  purchasing 
behaviors for thermal and metallurgical coal, limits on trade with the United States or other potentially adverse economic 
outcomes. Additionally, we sell coal into the export thermal and metallurgical markets. Accordingly, our international 
sales could also be impacted by the tariffs and other restrictions on trade between the United States and other countries. 
While tariffs and other retaliatory trade measures imposed by other countries on United States goods have not yet had a 
significant impact on our business or results of operations, we cannot predict further developments, and such existing or 
future tariffs could have a material adverse effect on our results of operations, financial position and cash flows and could 
reduce our revenues and cash available for distribution. 

Global geopolitical tensions have caused, and may cause in the future, significant market disruptions that may 

lead to increased volatility in the price of commodities, including oil & gas, coal, and other sources of energy.  

Volatility in coal and oil & gas prices has been and may continue to be heightened as a result of the ongoing Russian-
Ukrainian conflict, continued hostilities in the Middle East between Israel and Hamas and the potential impact to global 
shipping caused by Houthi rebels in Yemen. Globally, various governments have banned imports from Russia including 
commodities such as oil & gas and coal. These events have caused volatility in the aforementioned commodity markets. 
Although we have not experienced any material adverse effect on our results of operations, financial condition or cash 
flows as a result of such conflicts or the resulting volatility, such volatility, may significantly affect prices for our coal and 
oil & gas or the cost of supplies and equipment, as well as the prices of competing sources of energy for our electric power 
plant customers. 

Global  geopolitical  conflicts,  trade  and  monetary  sanctions,  as  well  as  any  escalation  of  the  conflict  and  future 
developments, could significantly affect worldwide market prices and demand for our coal and oil & gas and cause turmoil 
in  the  capital  markets  and  generally  in  the  global  financial  system.  Additionally,  the  geopolitical  and  macroeconomic 
consequences  of  such  conflicts  and  any  associated  sanctions  cannot  be  predicted  but  could  severely  impact  the  world 
economy. If any of these events occur, the resulting political instability and societal disruption could reduce overall demand 
for products, causing a reduction in our revenues or an increase in our costs and thereby materially and adversely affecting 
our results of operations. 

38 

 
 
 
 
 
 
Changes in consumption patterns by utilities regarding the use of coal, including plans by utilities to shut down or 
move away from coal-fired generation, have affected our ability to sell the coal we produce and may do so in the future.  

Our business is closely linked to the demand for electricity, and any changes in coal consumption by domestic or 
international electric power generators would likely impact our business over the long term. The domestic electric power 
sector accounts for the vast majority of the total domestic coal consumption. The amount of coal consumed by the domestic 
electric utility industry is affected primarily by the overall demand for electricity, environmental and other governmental 
regulations, and the price and availability of competing fuels for power plants such as nuclear, natural gas, and fuel oil as 
well  as  alternative  sources  of  energy.  Competition from  natural  gas-fired  plants  that  are relatively  more  efficient,  less 
expensive to construct, and less difficult to permit than coal-fired plants has the most potential to displace a significant 
amount of coal-fired electric power generation in the near term, particularly from older, less efficient coal-fired powered 
generators. 

Future environmental regulation of GHG emissions also could accelerate the use by utilities of fuels other than coal.  
In addition, federal and state mandates for increased use of electricity derived from renewable energy sources could affect 
demand for coal. Such mandates, combined with other incentives to use renewable energy sources such as tax credits, 
could make alternative fuel sources more competitive with coal. Further, far-reaching federal regulations promulgated by 
the EPA in the last several years, such as CSAPR and MATS, have led to the premature retirement of coal-fired generating 
units and a significant reduction in the amount of coal-fired generating capacity in the United States. A decrease in coal 
consumption by the domestic electric utility industry could adversely affect the demand for or the price of coal, which 
could negatively impact our results of operations and reduce our cash available for distribution. 

Other  factors,  such  as  efficiency  improvements  associated  with  technologies  powered  by  electricity  have  slowed 
electricity  demand  growth  and  could  contribute  to  slower  growth  in  the  future.  Further  decreases  in  the  demand  for 
electricity, such as decreases that could be caused by a worsening of current economic conditions, could have a material 
adverse effect on the demand for coal and our business over the long term. 

We, our customers, or the Operators of our oil & gas mineral interests could be subject to litigation related to 

climate change. 

Increasing  attention  to  climate  change  risk  has  also  resulted  in  a  recent  trend  of  governmental  investigations  and 
private litigation by state and local governmental agencies as well as private plaintiffs in an effort to hold energy companies 
accountable for the alleged effects of climate change. Other public nuisance lawsuits have been brought in the past against 
power, coal, and oil & gas companies alleging that their operations are contributing to climate change. The plaintiffs in 
these suits sought various remedies, including punitive and compensatory damages and injunctive relief. While the U.S. 
Supreme Court held that federal common law provided no basis for public nuisance claims against the defendants in those 
cases,  tort-type  liabilities  remain  a  possibility  and  a  source  of  concern.  Government  entities  in  other  states  (including 
California and New York) have brought similar claims seeking to hold a wide variety of companies that produce fossil 
fuels liable for the alleged impacts of the GHG emissions attributable to those fuels. Those lawsuits allege damages as a 
result of climate change and the plaintiffs are seeking unspecified damages and abatement under various tort theories.  
Separately, litigation has been brought against certain fossil-fuel companies alleging that they have been aware of the 
adverse  effects  of  climate  change  for  some  time  but  failed  to  adequately  disclose  such  impacts  to  their  investors  or 
consumers. We have not been made a party to these other suits, but it is possible that we could be included in similar future 
lawsuits initiated by state and local governments as well as private claimants. 

Litigation  resulting  from  disputes  with  our  customers  could  result  in  substantial  costs,  liabilities,  and  loss  of 

revenues. 

From time to time, we have disputes with our customers over the provisions of coal supply contracts relating to, among 
other things, coal pricing, quality, quantity, and the existence of specified conditions beyond our or our customers' control 
that suspend performance obligations under the particular contract. Disputes could occur in the future and we may not be 
able to resolve those disputes in a satisfactory manner, which could have a material adverse effect on our business, financial 
condition, and results of operations.   

39 

 
 
 
 
 
 
 
 
 
Our profitability could decline due to unanticipated mine operating conditions and other events that are not within 

our control and that may not be fully covered under our insurance policies. 

Our coal mining operations are influenced by changing conditions or events that can affect production levels and costs 
at particular mines for varying lengths of time and, as a result, can diminish our profitability. These conditions and events 
include, among others: 

•  mining and processing equipment failures and unexpected maintenance problems; 
• 
• 
• 
• 
• 
•  weather  conditions,  such  as  heavy  rains,  flooding,  ice,  and  other  natural  events  affecting  operations, 

unavailability of required equipment; 
prices for fuel, steel, explosives, and other supplies; 
fines and penalties incurred as a result of alleged violations of environmental and safety laws and regulations; 
variations in the thickness of the layer, or seam, of coal; 
amounts of overburden, partings, rock, and other natural materials; 

transportation, or customers; 
accidental mine water discharges and other geological conditions; 
fires; 
seismic activities, ground failures, rock bursts or structural cave-ins or slides; 
employee injuries or fatalities; 
labor-related interruptions; 
increased reclamation costs; 
inability to acquire, maintain or renew mining rights or permits in a timely manner, if at all; 
fluctuations in transportation costs and the availability or reliability of transportation; and 
unexpected operational interruptions due to other factors. 

• 
• 
• 
• 
• 
• 
• 
• 
• 

These conditions have the potential to significantly impact our operating results. Prolonged disruption of production 
at any of our mines would result in a decrease in our revenues and profitability, which could materially adversely impact 
our quarterly or annual results. 

Effective October 1, 2023, we renewed our property and casualty insurance program through September 30, 2024. 
Our property insurance was procured from our wholly owned captive insurance company, Wildcat Insurance. Wildcat 
Insurance charged certain of our subsidiaries for the premiums on this program and in return purchased reinsurance for the 
program in the standard market. The maximum limit in the commercial property program is $100.0 million per occurrence, 
excluding  a  $1.5  million  deductible  for  property  damage,  a  75  or  90  day  waiting  period  for  underground  business 
interruption depending on the mining complex and an additional $25.0 million overall aggregate deductible. We retained 
a 7.25% participating interest in our current commercial property insurance program. We can make no assurances that we 
will not experience significant insurance claims in the future that could have a material adverse effect on our business, 
financial condition, results of operations and ability to purchase property insurance in the future. Also, exposures exist for 
which no insurance may be available and for which we have not reserved. In addition, the insurance industry has been 
subject to efforts by environmental activists to restrict coverages available for fossil-fuel companies. 

We could be unable to obtain and renew permits necessary for our coal mining operations, which could reduce our 

production, cash flow, and profitability. 

Mining  companies  must  obtain  numerous  governmental  permits  or  approvals  that  impose  strict  conditions  and 
obligations relating to various environmental and safety matters in connection with coal mining. The permitting rules are 
complex and can change over time. Regulatory authorities exercise considerable discretion in the timing and scope of 
permit issuance. The public has the right to comment on permit applications and otherwise participate in the permitting 
process, including through court intervention. Accordingly, permits required to conduct our operations may not be issued, 
maintained, or renewed, may not be issued or renewed in a timely fashion, or may involve requirements that restrict our 
ability to economically conduct our mining operations. Limitations on our ability to conduct our mining operations due to 
the  inability  to  obtain  or  renew  necessary  permits  or  similar  approvals  could  reduce  our  production,  cash  flow,  and 
profitability.  Please  read  "Item  1.  Business—Environmental,  Health  and  Safety  Regulations—Mining  Permits  and 
Approvals." 

40 

 
 
 
 
 
 
 
The  EPA  has  begun  reviewing  permits  required  for  the  discharge  of  overburden  from  mining  operations  under 
Section 404 of the CWA. Various initiatives by the EPA regarding these permits have increased the time required to obtain 
and the costs of complying with such permits. In addition, the EPA previously exercised its "veto" power to withdraw or 
restrict the use of previously issued permits in connection with one of the largest surface mining operations in Appalachia.  
The EPA's action was ultimately upheld by a federal court. As a result of these developments, we could be unable to obtain 
or experience delays in securing, utilizing, or renewing Section 404 permits required for our operations, which could have 
an adverse effect on our results of operation and financial position. Please read "Item 1. Business—Environmental, Health 
and Safety Regulations—Water Discharge." 

In addition, some of our permits could be subject to challenges from the public, which could result in additional costs 
or  delays  in  the  permitting  process  or  even  an  inability  to  obtain  permits,  permit  modifications,  or  permit  renewals 
necessary for our operations. 

Fluctuations in transportation costs and the availability or reliability of transportation could reduce revenues by 

causing us to reduce our production or by impairing our ability to supply coal to our customers. 

Transportation costs represent a significant portion of the total cost of coal for our customers and, as a result, the cost 
of transportation is a critical factor in a customer's purchasing decision. Increases in transportation costs could make coal 
a less competitive source of energy or could make our coal production less competitive than coal produced from other 
sources. Disruption of transportation services due to weather-related problems, flooding, drought, accidents, mechanical 
difficulties,  strikes,  lockouts,  bottlenecks,  or  other  events  could  temporarily  impair  our  ability  to  supply  coal  to  our 
customers. Our transportation providers could face difficulties in the future that could impair our ability to supply coal to 
our  customers,  resulting  in  decreased  revenues.  If  there  are  disruptions  in  the  transportation  services  provided  by  our 
primary rail or barge carriers that transport our coal and we are unable to find alternative transportation providers to ship 
our coal, our business could be adversely affected. 

Conversely, significant decreases in transportation costs could result in increased competition from coal producers in 
other parts of the country. For instance, difficulty in coordinating the many eastern coal loading facilities, the large number 
of small shipments, the steeper average grades of the terrain, and a more unionized workforce are all issues that combine 
to make coal shipments originating in the eastern United States inherently more expensive on a per-mile basis than coal 
shipments  originating  in  the  western  United  States.  Historically,  high  coal  transportation  rates  from  the  western  coal-
producing areas into certain eastern markets limited the use of western coal in those markets. Lower rail rates from the 
western coal-producing areas to markets served by eastern United States coal producers have created major competitive 
challenges for eastern coal producers. In the event of further reductions in transportation costs from western coal-producing 
areas, the increased competition with certain eastern coal markets could have a material adverse effect on our business, 
financial condition, and results of operations. 

States in which our coal is transported by truck may modify or increase enforcement of their laws regarding weight 
limits or coal trucks on public roads. Such legislation and enforcement efforts could result in shipment delays and increased 
costs. An increase in transportation costs could have an adverse effect on our ability to increase or maintain production 
and could adversely affect revenues. 

Political  or  financial  instability,  currency  fluctuations,  the  outbreak  of  pandemics  or  other  illnesses  (such  as  the 
COVID-19 pandemic), labor unrest, transport capacity and costs, port security, weather conditions, natural disasters, or 
other events that could alter or suspend our operations, slow or disrupt port activities, or affect foreign trade are beyond 
our control and could materially disrupt our ability to participate in the export market for coal sales, which could adversely 
affect our sales and our results of operations. 

Unexpected increases in raw material costs could significantly impair our operating profitability. 

Our  coal  mining  operations  are  affected  by  commodity  prices.  We  use  significant  amounts  of  steel,  petroleum 
products, and other raw materials in various pieces of mining equipment, supplies, and materials, including the roof bolts 
required by the room-and-pillar method of mining. Steel prices and the prices of scrap steel, natural gas, and coking coal 
consumed in the production of iron and steel fluctuate significantly and could change unexpectedly. Inflationary pressures 
have and could continue to lead to price increases affecting many of the components of our operating expenses such as 
fuel, steel, and maintenance expenses. There could be acts of nature or terrorist attacks or threats that could also impact 

41 

 
 
 
 
 
 
 
 
the future costs of raw materials. Future volatility in the price of steel, petroleum products, or other raw materials will 
impact our operational expenses and could result in significant fluctuations in our profitability. 

A shortage of skilled labor may make it difficult for us to maintain labor productivity and competitive costs and 

could adversely affect our profitability.  

Efficient coal mining using modern techniques and equipment requires skilled laborers, preferably with at least one 
year of experience and proficiency in multiple mining tasks. In recent years, a shortage of experienced coal miners has 
caused us to include some inexperienced staff in the operation of certain mining units, which decreases our productivity 
and increases our costs. This shortage of experienced coal miners is the result of a significant percentage of experienced 
coal miners reaching retirement age, combined with the difficulty of retaining existing workers and attracting new workers 
to  the  coal  industry. Thus,  this  shortage  of  skilled  labor  could  continue  over  an  extended  period.  If  the  shortage  of 
experienced labor continues or worsens, it could have an adverse impact on our labor productivity and costs and our ability 
to  expand  production  in  the  event  there  is  an  increase  in  the  demand  for  our  coal,  which  could  adversely  affect  our 
profitability.  

Disruptions in supply chains could significantly impair our operating profitability. 

We are dependent upon vendors to supply mining equipment, safety equipment, supplies, and materials. If a vendor 
fails to deliver on its commitments, or if common carriers have difficulty providing capacity to meet demands for their 
services, we could experience reductions in our production or increased production costs, which could lead to reduced 
profitability and adversely affect our results of operations. 

Inflationary pressures could significantly impair our operating profitability. 

Any future inflationary or deflationary pressures could adversely affect the results of our operations. For example, at 
times our results have been significantly impacted by price increases affecting many of the components of our operating 
expenses such as fuel, steel, maintenance expense and labor. In addition to potential cost increases, inflation could cause 
a decline in global or regional economic conditions that reduce demand for our coal or oil & gas and could adversely affect 
our results of operations. 

The unavailability of an adequate supply of coal mineral reserves and resources that can be mined at competitive 

costs could cause our profitability to decline. 

Our  profitability  depends  substantially  on  our  ability  to  mine  coal  mineral  reserves  and  resources  that  have  the 
geological  characteristics  that  enable  them  to  be  mined  at  competitive  costs  and  to  meet  the  quality  needed  by  our 
customers. Because we deplete our reserves and resources as we mine coal, our future success and growth depend, in part, 
upon our ability to acquire additional coal mineral reserves and resources that are economically recoverable. Replacement 
reserves and resources may not be available when required or, if available, may not be mineable at costs comparable to 
those of the depleting mines. We may not be able to accurately assess the geological characteristics of any reserves or 
resources that we acquire, which could adversely affect our profitability and financial condition. Exhaustion of reserves 
and resources at particular mines also could have an adverse effect on our operating results that is disproportionate to the 
percentage of overall production represented by such mines. Our ability to obtain other reserves and resources in the future 
could be limited by restrictions under our existing or future debt agreements, competition from other coal companies for 
attractive properties, the lack of suitable acquisition candidates, or the inability to acquire coal properties on commercially 
reasonable terms. 

The estimates of our coal mineral reserves and resources could prove inaccurate and could result in decreased 

profitability. 

The estimates of our coal mineral reserves and resources could vary substantially from the actual amounts of coal we 
are able to economically recover. The reserve and resource data set forth in "Item 2. Properties—Coal Mineral Resources 
and  Reserves"  represent  engineering  estimates.  All  of  the  coal  mineral  reserves  presented  in  this  Annual  Report  on 
Form 10-K  constitute  proven  and  probable  mineral  reserves.  There  are  numerous  uncertainties  inherent  in  estimating 
quantities of reserves and resources, including many factors beyond our control. Estimates of coal mineral reserves and 

42 

 
 
 
 
 
 
 
 
 
 
 
resources necessarily depend upon a number of variables and assumptions, any one of which could vary considerably from 
actual results. These factors and assumptions relate to: 

• 

• 
• 
• 
• 
• 

geological and mining conditions, which may not be fully identified by available exploration data and/or differ 
from our experiences in areas where we currently mine; 
the percentage of coal in the ground ultimately recoverable; 
historical production from the area compared with production from other producing areas; 
the assumed effects of regulation and taxes by governmental agencies;  
future improvements in mining technology; and 
assumptions concerning future coal prices, operating costs, capital expenditures, severance and excise taxes, and 
development and reclamation costs. 

Each of the factors which impacts reserve and resource estimation may vary considerably from the assumptions used 
in making the estimation and, as a result, the estimates in this report may not accurately reflect our actual coal reserves 
and resources. Actual production, revenues and expenditures with respect to our coal reserves will likely vary from the 
assumptions used in these estimates, and these variances may be material. Government regulations and other pressures 
may result in the closure of coal-fired electric generating plants earlier than assumed. Such changes would reduce the 
economic viability of our mining operations and could have a material adverse impact on our operations and financial 
results.  

Coal mining in certain areas in which we operate is more difficult and involves more regulatory constraints than 
mining in other areas of the United States, which could affect the mining operations and cost structures of these areas. 

The  geological  characteristics  of  some  of  our  coal  mineral  reserves,  such  as  depth  of  overburden  and  coal  seam 
thickness, make them difficult and costly to mine. As mines become depleted, replacement reserves may not be available 
when  required  or,  if  available,  may  not be  mineable  at  costs  comparable  to  those  of  the  depleting  mines.  In  addition, 
permitting,  licensing,  and  other  environmental  and  regulatory  requirements  associated  with  certain  of  our  mining 
operations are more costly and time-consuming to satisfy. Subsidence issues are particularly important to our operations 
engaged in longwall mining. Failure to timely and economically secure subsidence rights or any associated mitigation 
agreements  could  materially  affect  our  results  by  causing  delays  or  changes  in  our  mining  plan.  These  factors  could 
materially adversely affect the mining operations and cost structures of, and our customers' ability to use coal produced 
by, our mines.  

Extensive environmental laws and regulations affect coal consumers and could affect the demand for coal as a 

fuel source. 

Federal, state, and local laws and regulations extensively regulate the amount of sulfur dioxide, particulate matter, 
nitrogen oxides, mercury, and other compounds emitted into the air from coal-fired electric power plants, which are the 
ultimate consumers of much of our coal. These laws and regulations can require significant emission control expenditures 
for  many  coal-fired  power  plants,  and  various  new  and  proposed  laws  and  regulations  could  require  further  emission 
reductions and associated emission control expenditures. These laws and regulations could affect demand and prices for 
coal. There is also continuing pressure on federal and state regulators to impose limits on carbon dioxide emissions from 
electric power plants, particularly coal-fired power plants. Further, far-reaching federal regulations promulgated by the 
EPA in the last several years, such as CSAPR and MATS, have led to the premature retirement of coal-fired generating 
units and a significant reduction in the amount of coal-fired generating capacity in the United States. Please read "Item 1. 
Business—Environmental,  Health  and  Safety  Regulations—Air  Emissions,"  "—GHG  Emissions"  and  "—Hazardous 
Substances and Wastes." 

Our coal mining operations are subject to extensive and costly laws and regulations, and such current and future 

laws and regulations could increase current operating costs or limit our ability to produce coal. 

We are subject to numerous federal, state, and local laws and regulations affecting the coal mining industry, including 
laws and regulations pertaining to employee health and safety, permitting and licensing requirements, air and water quality 
standards, plant and wildlife protection, reclamation and restoration of mining properties after mining is completed, the 
discharge or release of materials into the environment, surface subsidence from underground mining, and the effects that 
mining  has  on  groundwater  quality  and  availability.  Certain  of  these  laws  and  regulations  may  impose  strict  liability 
without regard to fault or legality of the original conduct. Failure to comply with these laws and regulations may result in 

43 

 
 
 
 
 
 
 
 
the assessment of administrative, civil, and criminal penalties, the imposition of remedial liabilities, and the issuance of 
injunctions limiting or prohibiting the performance of operations. Complying with these laws and regulations could be 
costly and time-consuming and could delay the commencement or continuation of exploration or production operations.  
The  possibility  exists  that  new  laws  or  regulations  may  be  adopted,  or  that  judicial  interpretations  or  more  stringent 
enforcement of existing laws and regulations may occur, which could materially affect our mining operations, cash flow, 
and profitability, either through direct impacts on our mining operations, or indirect impacts that discourage or limit our 
customers' use of coal. Please read "Item 1. Business—Environmental, Health and Safety Regulations." 

Federal and state laws addressing mine safety practices impose stringent reporting requirements and civil and criminal 
penalties for violations. Federal and state regulatory agencies continue to interpret and implement these laws and propose 
new  regulations  and  standards.  Implementing  and  complying  with  these  laws  and  regulations  has  increased  and  will 
continue to increase our operational expenses and have an adverse effect on our results of operation and financial position.  
For more information, please read "Item 1. Business—Environmental, Health and Safety Regulations—Mine Health and 
Safety Laws." 

Oil & gas operations are subject to various governmental laws and regulations. Compliance with these laws and 
regulations can be burdensome and expensive for the Operators, and failure to comply could result in the Operators 
incurring significant liabilities, either of which could impact the Operators' willingness to develop our interests.  

The Operators' operations on the properties in which we hold interests are subject to various federal, state, and local 
governmental regulations that may change from time to time in response to economic and political conditions. Matters 
subject to regulation include drilling operations, production and distribution activities, discharges or releases of pollutants 
or wastes, plugging and abandonment of wells, maintenance and decommissioning of other facilities, the spacing of wells, 
unitization and pooling of properties, and taxation. From time to time, regulatory agencies have imposed price controls 
and limitations on production by restricting the rate of flow of oil & gas wells below actual production capacity to conserve 
supplies  of  oil  &  gas.  In  addition,  the  production,  handling,  storage,  and  transportation  of  oil  &  gas,  as  well  as  the 
remediation, emission, and disposal of oil & gas wastes, by-products thereof, and other substances and materials produced 
or used in connection with oil & gas operations are subject to regulation under federal, state, and local laws and regulations 
primarily relating to the protection of worker health and safety, natural resources, and the environment. Failure to comply 
with these laws and regulations may result in the assessment of sanctions on the Operators, including administrative, civil, 
or  criminal  penalties,  permit  revocations,  requirements  for  additional  pollution  controls,  and  injunctions  limiting  or 
prohibiting some or all of the Operators' operations on our properties. Moreover, these laws and regulations have generally 
imposed increasingly strict requirements related to water use and disposal, air pollution control, and waste management. 
Laws and regulations governing exploration and production may also affect production levels. The Operators must comply 
with federal and state laws and regulations governing conservation matters, including: 

• 
• 
• 
• 
• 

provisions related to the unitization or pooling of the oil & gas properties; 
the establishment of maximum rates of production from wells; 
the spacing of wells; 
the plugging and abandonment of wells; and 
the removal of related production equipment. 

Additionally,  federal  and  state  regulatory  authorities  may  expand  or  alter  applicable  pipeline-safety  laws  and 
regulations,  compliance  with  which  could  require  increased  capital  costs  for  third-party  oil  &  gas  transporters.  These 
transporters may attempt to pass on such costs to the Operators, which in turn could affect profitability on the properties 
in which we own mineral interests. 

The Operators must also comply with laws and regulations prohibiting fraud and market manipulations in energy 
markets. To the extent the operators of our properties are shippers on interstate pipelines, they must comply with the tariffs 
of those pipelines and with federal policies related to the use of interstate capacity. The Operators may be required to make 
significant expenditures to comply with the governmental laws and regulations described above and may be subject to 
potential fines and penalties if they are found to have violated these laws and regulations. We believe the trend of more 
expansive and stricter environmental legislation and regulations will continue. These current laws and regulations and 
other potential regulations could increase the operating costs of the Operators and delay production and could ultimately 
impact the Operators' ability and willingness to develop our properties. 

44 

 
 
 
 
 
 
 
Federal and state legislative and regulatory initiatives relating to hydraulic fracturing could result in increased 
costs, additional operating restrictions or delays, and fewer potential drilling locations, which could adversely affect 
revenues from our mineral interests. 

Oil & gas production on the properties in which we hold mineral interests utilizes hydraulic fracturing. Hydraulic 
fracturing is a common practice that is used to stimulate the production of hydrocarbons from tight formations, including 
shales. The process involves the injection of water, sand, and chemicals under pressure into formations to fracture the 
surrounding rock and stimulate production. The Federal Safe Drinking Water Act regulates the underground injection of 
substances through the UIC program. Hydraulic fracturing is generally exempt from regulation under the UIC program, 
and the hydraulic-fracturing process is typically regulated by state oil & gas commissions. 

Several states where we own interests, including Texas and Oklahoma, have adopted regulations that could restrict or 
prohibit hydraulic fracturing in certain circumstances or require the disclosure of the composition of hydraulic-fracturing 
fluids. In addition to state laws, local land-use restrictions, such as city ordinances, may restrict or prohibit the performance 
of  well  drilling  in  general  or  hydraulic  fracturing  in  particular.  We  cannot  predict  what  additional  state  or  local 
requirements may be imposed in the future on oil & gas operations in the states in which we own interests. In the event 
state, local, or municipal legal restrictions are adopted in areas where the Operators conduct operations, the Operators 
could incur substantial costs to comply with these requirements, which could be significant in nature, experience delays, 
or curtailment in the pursuit of exploration, development, or production activities and perhaps even be precluded from the 
drilling of wells. 

There  has  been  increasing  public  controversy  regarding  hydraulic  fracturing  about  increased  risks  of  induced 
seismicity, the use of fracturing fluids, impacts on drinking water supplies, use of water, and the potential for impacts to 
surface water, groundwater, and the environment generally. A number of lawsuits and enforcement actions have been 
initiated  across  the  country  implicating  hydraulic-fracturing  practices.  If  new  laws  or  regulations  are  adopted  that 
significantly restrict hydraulic fracturing, those laws could make it more difficult or costly for the Operators to perform 
fracturing  to  stimulate  production  from  tight formations.  In  addition,  if  hydraulic fracturing  is  further  regulated  at  the 
federal or state level, fracturing activities on our properties could become subject to additional permitting and financial 
assurance  requirements,  more  stringent  construction  specifications,  increased  monitoring,  reporting  and  recordkeeping 
obligations, plugging and abandonment requirements, and also to attendant permitting delays and potential increases in 
costs. Legislative changes could cause operators to incur substantial compliance costs and adversely affect revenues from 
our mineral interests. At this time, it is not possible to estimate the impact on our business of newly enacted or potential 
federal or state legislation governing hydraulic fracturing. 

Legislation or regulatory initiatives intended to address seismic activity could restrict the Operators' drilling and 
production activities, as well as their ability to dispose of produced water gathered from such activities, which could 
have a material adverse effect on our business. 

State and federal regulatory agencies have recently focused on a possible connection between the hydraulic-fracturing 
related activities, particularly the underground injection of wastewater into disposal wells, and the increased occurrence 
of seismic activity, and regulatory agencies at all levels are continuing to study the possible linkage between oil & gas 
activity and induced seismicity.  

In addition, a number of lawsuits have been filed in other states, including in Oklahoma, alleging that disposal well 
operations have caused damage to neighboring properties or otherwise violated state and federal rules regulating waste 
disposal. In response to these concerns, regulators in some states are seeking to impose additional requirements, including 
requirements in the permitting of produced water disposal wells or otherwise to assess the relationship between seismicity 
and  the  use  of  such  wells.  For  example,  both  Texas  and  Oklahoma  have  imposed  certain  limits  on  the  permitting  or 
operation of disposal wells in areas with increased instances of induced seismic events. In September 2021, the TRRC 
issued a notice to operators in the Midland area to reduce saltwater disposal well activities and provide certain data to the 
TRRC. Subsequently, the TRRC ordered the indefinite suspension of all deep oil & gas-produced water injection wells in 
the  area,  effective  December  31,  2021.  Relatedly,  in  March  2022,  the  TRRC  began  implementation  of  its  Northern 
Culberson-Reeves Seismic Response Action Plan to address injection-induced seismicity with the goal to eliminate 3.5 
magnitude or greater earthquakes no later than December 31, 2023. In response to continued seismicity in the area, the 
TRRC issued a notice that it is suspending all disposal wells in the Northern Culberson-Reeves Seismic Response Area, 
effective January 12, 2024. 

45 

 
 
 
 
 
 
 
The adoption or implementation of any new laws or regulations that restrict the Operators' ability to use hydraulic 
fracturing or dispose of produced water gathered from drilling and production activities by limiting volumes, disposal 
rates, disposal well locations, or otherwise, or requiring the Operators to shut down or limit the operation of disposal wells, 
could have a material adverse effect on our business, financial condition and results of operations. 

Our coal operations, and the third-party operations related to our oil and gas mineral interests, are subject to a 

series of risks resulting from climate change. 

Combustion of fossil fuels, such as the coal we produce and the oil & gas produced from our mineral interests, results 
in the emission of carbon dioxide into the atmosphere. Concerns about the environmental impacts of such emissions have 
resulted in a series of regulatory, political, litigation, and financial risks for our business. Global climate issues continue 
to attract public and scientific attention. Most scientists have concluded that increasing concentrations of GHGs in the 
Earth's atmosphere could produce climate changes that have significant physical effects, such as increased frequency and 
severity of storms, droughts and floods, and other climatic events. Increasing government attention is being paid to global 
climate issues and to emissions of GHGs, including emissions due to fossil fuels. 

In the United States, no comprehensive climate change legislation has been implemented at the federal level. However, 
following the U.S. Supreme Court finding that GHG emissions constitute a pollutant under the CAA, the EPA has adopted 
regulations that, among other things, establish construction and operating permit reviews for GHG emissions from certain 
large stationary sources, require the monitoring and annual reporting of GHG emissions from certain sources in the United 
States, or constrain the emissions of powerplants (though such emissions restraints have been subject to challenge; for 
more information, see our regulatory disclosure titled "GHG emissions"). Additionally, the U.S. Congress approved, and 
President Biden signed into law, a resolution under the Congressional Review Act to repeal September 2020 revisions to 
methane standards, effectively reinstating the more stringent 2016 standards. Furthermore, in December 2023, EPA issued 
its  final  methane  rules,  known  as  OOOOb  and  OOOOc,  that  established  new  sources  and  first-time  existing  source 
standards of performance for methane and volatile organic compound emissions for oil & gas facilities. The final rules 
include  nationwide  emissions  guidelines  for  states  to  limit  methane  emissions  from  existing  crude  oil  and  natural  gas 
facilities and states have two years to prepare and submit their plants to impose methane emission controls on existing 
sources. The rules also revise requirements for fugitive emissions monitoring and repair as well as equipment leaks and 
the  frequency  of  monitoring  surveys  and  establishes  a  "super-emitter"  response  program  to  timely  mitigate  emissions 
events. It is likely that the final rule will be subject to legal challenges. Moreover, compliance with the new rules may 
effect the amount oil and gas companies owe under the Inflation Reduction Act, which amended the CAA to impose a 
first-time fee on the emission of methane from sources required to report their GHG emissions to the EPA. The methane 
emissions  fee  applies  to  excess  methane  emissions  from  certain  facilities  and  starts  at  $900  per  metric  ton  of  leaked 
methane in 2024 and increases to $1,200 in 2025 and $1,500 in 2026 and thereafter.  Compliance with the EPA’s new 
final rules would exempt an otherwise covered facility from the requirement to pay the methane fee. We cannot predict 
the scope of any final methane regulatory requirements or the cost for the Operators to comply with such requirements. 
However,  given  the  long-term  trend  toward  increasing  regulation,  future  federal  GHG  regulations  of  the  oil  and  gas 
industry remain a significant possibility and may have an impact on drilling operations on our oil & gas mineral interests. 

Separately, various states and groups of states have adopted or are considering adopting legislation, regulations, or 
other regulatory initiatives that are focused on such areas as GHG cap-and-trade programs, carbon taxes, reporting and 
tracking programs, and restriction of emissions. Internationally, the Paris Agreement requires member states to submit 
non-binding, individually-determined emissions reduction targets. These commitments could further reduce demand and 
prices for fossil fuels. Although the United States had withdrawn from the Paris Agreement, following President Biden's 
executive  order  in  January  2021,  the  United  States  rejoined  the  Agreement  and,  in  April  2021,  established  a  goal  of 
reducing  economy-wide  net  GHG  emissions  50-52%  below  levels  by  2030.  Additionally,  at  COP26  in  Glasgow  in 
November 2021, the United States and the European Union jointly announced the launch of a Global Methane Pledge 
committing to a collective goal of reducing global methane emissions by at least 30% from 2020 levels by 2030, including 
"all feasible reductions" in the energy sector. At COP27 in Sharm El-Sheik in November 2022, countries reiterated the 
agreements from COP26 and were called upon to accelerate efforts toward the phase out of inefficient fossil fuel subsidies. 
The  United  States  also  announced,  in  conjunction  with  the  European  Union  and  other  partner  countries,  that  it  would 
develop  standards  for  monitoring  and  reporting  methane  emissions  to  help  create  a  market  for  low  methane-intensity 
natural gas. Although no firm commitment or timeline to phase out or phase down all fossil fuels was made at COP27, 
there can be no guarantees that countries will not seek to implement such a phase out in the future. In December 2023, the 
United Arab Emirates hosted COP28 where parties agreed to transition "away from fossil fuels in energy systems in a just, 
orderly and equitable manner" and increase renewable energy capacity so as to achieve net zero by 2050, although no 

46 

 
 
 
 
timeline for doing so was set.  The full impact of these actions is uncertain at this time and it is unclear what additional 
initiatives may be adopted or implemented that may have adverse effects on us and the Operators' operations. 

Governmental,  scientific,  and  public  concern  over  climate  change  has  also  resulted  in  increased  political  risks, 
including certain climate-related pledges made by certain candidates now in political office. In January 2021, President 
Biden issued an executive order that commits to substantial action on climate change, calling for, among other things, the 
increased use of zero-emissions vehicles by the federal government, the elimination of subsidies provided to the fossil-
fuel industry, a doubling of electricity generated by offshore wind by 2030, and increased emphasis on climate-related 
risks  across  governmental  agencies  and  economic  sectors.  Other  actions  that  may  be  pursued  include  restrictive 
requirements on new pipeline infrastructure or fossil-fuel export facilities or the promulgation of a carbon tax or cap and 
trade program. Further, although Congress has not passed such legislation, almost half of the states have begun to address 
GHG  emissions,  primarily  through  the  planned  development  of  emissions  inventories,  regional  GHG  cap  and  trade 
programs, or the establishment of renewable energy requirements for utilities. Depending on the particular program, we, 
our  customers,  or  operators  of  our  mineral  interests  could  be  required  to  control  GHG  emissions  or  to  purchase  and 
surrender  allowances  for  GHG  emissions  resulting  from  our  operations.  Litigation risks  are  also  increasing.  For  more 
information, see our risk factor titled "We, our customers, or the Operators of our oil & gas mineral interests could be 
subject to litigation related to climate change." 

Apart from governmental regulation, there are also increasing financial risks for fossil-fuel producers as stakeholders 
of fossil-fuel energy companies may elect in the future to shift some or all of their support into non-energy related sectors. 
Institutional lenders who provide financing to fossil-fuel energy companies also have become more attentive to sustainable 
lending practices and some of them may elect not to provide funding for fossil-fuel energy companies. For example, at 
COP26, the GFANZ announced that commitments from over 450 firms across forty-five countries had resulted in over 
$130 trillion in capital committed to net zero goals. The various sub-alliances of GFANZ generally require participants to 
set  short-term,  sector-specific  targets  to  transition  their  financing,  investing,  and/or  underwriting  activities  to  net  zero 
emissions by 2050. There is also a risk that financial institutions will be required to adopt policies that have the effect of 
reducing the funding provided to the fossil-fuel sector. For example, in October 2023, the Federal Reserve, Office of the 
Comptroller of the Currency and the Federal Deposit Insurance Corp. released a finalized set of principles guiding financial 
institutions with $100 billion or more in assets on the management of physical and transition risks associated with climate 
change on specific assets of the banks' portfolio. Although we cannot predict the effects of these actions, such limitation 
of investments in and financing, bonding, and insurance coverages for fossil-fuel energy companies could adversely affect 
our coal mining or oil & gas production activities. 

Separately, the SEC released a proposed rule in March 2022 that would establish a framework for the reporting of 
climate risks, targets and metrics. A final rule is anticipated to be released in the second quarter of 2024. The SEC has also 
announced that it is scrutinizing existing climate-change related disclosures in public filings, increasing the potential for 
enforcement if the SEC were to allege that an issuer’s existing climate disclosures are misleading, deceptive, or deficient. 
Such agency action could also increase the potential for private litigation. Relatedly, California has enacted new laws 
requiring additional disclosure with respect to certain climate-related risks and GHG emission reduction claims. Other 
states are considering similar laws. Non-compliance with these new laws may result in the imposition of substantial fines 
or penalties. Any new laws or regulations imposing more stringent requirements on our business related to the disclosure 
of climate related risks may result in reputation harms among certain stakeholders if they disagree with our approach to 
mitigating  climate-related  risks,  increased  compliance  costs  resulting  from  the  development  of  any  disclosures,  and 
increased costs of and restrictions on access to capital to the extent we do not meet any climate-related expectations or 
requirements of financial institutions. 

The adoption and implementation of new or more stringent international, federal, or state legislation, regulations, or 
other regulatory  initiatives  that  impose more  stringent  standards  for  GHG  emissions  from  fossil-fuel  companies  could 
result in increased costs of compliance or costs of consuming, and thereby reduce demand for coal and oil & gas, which 
could reduce the profitability of our interests. Additionally, political, litigation, and financial risks could result in either us 
or oil & gas operators restricting or canceling mining or oil & gas production activities, incurring liability for infrastructure 
damages as a result of climatic changes, or having an impaired ability to continue to operate economically. One or more 
of  these  developments,  as  well  as  concerted  conservation  and  efficiency  efforts  that  result  in  reduced  electricity 
consumption, and consumer and corporate preferences for non-fossil-fuel sources, including alternative energy sources, 

47 

 
 
 
 
could cause prices and sales of our coal and/or oil & gas to materially decline and could cause our costs to increase and 
adversely affect our revenues and results of operations. 

Climate  change may  also  result  in various  physical  risks, such  as  the  increased  frequency  or  intensity  of  extreme 
weather events or changes in meteorological and hydrological patterns that could adversely impact our operations, as well 
as those of the Operators and their supply chain. Such physical risks may result in damage to our facilities or the Operators' 
facilities  or  otherwise  adversely  impact  operations  which  could  decrease  the  production  attributable  to  our  mineral 
interests. We may not have insurance to cover these risks and the consequences for our or their operations could have a 
negative impact on the costs and revenues from operations. 

Some of our operating subsidiaries lease a portion of the surface properties upon which their mining facilities are 

located. 

Our operating subsidiaries do not, in all instances, own all of the surface properties upon which their mining facilities 
have been constructed. Certain of the operating companies have constructed and now operate all or some portion of their 
facilities on properties owned by third parties with whom our subsidiary has entered into a long-term lease. We have no 
reason to believe that there exists any risk of loss of these leasehold rights given the terms and provisions of the subject 
leases and the nature and identity of the third-party lessors; however, in the unlikely event of any loss of these leasehold 
rights,  operations  could  be  disrupted  or  otherwise  adversely  impacted  as  a  result  of  increased  costs  associated  with 
retaining the necessary land use. 

Federal and state laws require bonds to secure our obligations related to statutory reclamation requirements and 
workers' compensation and black lung benefits. Our inability to acquire or failure to maintain surety bonds that are 
required by federal and state law would have a material adverse effect on us. 

Federal  and  state  laws  require  us  to  maintain  bonds  to  secure  our  obligations  to  repair  and  return  property  to  its 
approximate original state after it has been mined (often referred to as "reclaim" or "reclamation"), to pay federal and state 
workers' compensation and pneumoconiosis (or black lung) benefits, and to satisfy other miscellaneous obligations. These 
bonds provide assurance that we will perform our statutorily required obligations and are referred to as "surety" bonds.  
These bonds are typically renewable on a yearly basis. At December 31, 2023, our total of such bonds was $246.9 million.  
The amount of surety bonding we are required to maintain may be increased by the governmental agencies holding the 
bond. For example, federal and state regulators are considering making financial assurance requirements more stringent 
and costly with respect to self-insured coal workers' pneumoconiosis, mine closure and reclamation security amounts.  

We could have difficulty acquiring or maintaining surety bonds for a variety of reasons, including:  

• 
• 

• 

• 

substantial increases in the amount of bonding required; 
lack of availability, higher expense, or unreasonable terms of new surety bonds, including as a result of external 
pressures related to fossil-fuel companies; 
the ability of current and future surety bond issuers to increase required collateral, or limitations on the availability 
of collateral for surety bond issuers due to the terms of our credit agreements; and 
the exercise by third-party surety bondholders of their rights to refuse to renew the surety. 

Failure to acquire or maintain the required bonds could subject us to fines and penalties, result in the loss of our mining 
permits, or imperil our ability to self-insure workers compensation and pneumoconiosis obligations, and could have a 
material adverse effect on us. 

We  depend  on  unaffiliated  Operators  for  all  of  the  exploration,  development,  and  production  of  the  oil  &  gas 

properties in which we own mineral interests.  

Because we depend on unaffiliated third-party operators for all of the exploration, development, and production of 
our oil & gas properties, we have little to no control over the operations related to our oil & gas properties. The operators 
of our properties are often not obligated to undertake any development activities. In the absence of a specific contractual 
obligation, any development and production activities will be subject to their sole discretion (subject, however, to certain 
implied obligations to develop imposed by state law). The success and timing of drilling and development activities on 
our oil & gas properties, and whether the operators elect to drill any additional wells on our acreage, depends on a number 
of factors that will be largely outside of our control, including: 

48 

 
 
 
 
 
 
 
 
 
 
• 

• 
• 
• 

• 
• 
• 

• 
• 
• 

the  capital  costs  required  for  drilling  activities  by  the  operators  of  our  oil  &  gas  properties,  which  could  be 
significantly more than anticipated; 
the ability of the operators of our properties to access capital;  
prevailing commodity prices; 
the  availability  of  suitable  drilling  equipment,  production  and  transportation  infrastructure,  and  qualified 
operating personnel; 
the operators' expertise, operating efficiency, and financial resources; 
approval of other participants in drilling wells; 
the operators' expected return on investment in wells drilled on our acreage as compared to opportunities in other 
areas; 
the selection of technology; 
the selection of counterparties for the marketing and sale of production; and 
the rate of production of the reserves. 

The Operators may elect not to undertake development activities or may undertake these activities in an unanticipated 

fashion, which could result in significant fluctuations in our oil & gas revenues. 

We have little to no control over the timing of future drilling with respect to our oil & gas mineral interests. 

All of our oil & gas mineral interests may not ultimately be developed or produced by the operators of our properties. 
Recovery  of undeveloped reserves  requires  significant  capital  expenditures  and  successful  drilling  operations,  and  the 
decision to pursue the development of an undeveloped drilling location will be made by the operator and not by us. We 
generally do not have access to the estimated costs of development of these reserves or the scheduled development plans 
of  the  Operators.  Our  estimate  of  reserves  assumes  that  substantial  capital  expenditures  are  required  to  develop  the 
reserves. We cannot be certain that the estimated costs of the development of these reserves are accurate, that development 
will occur as scheduled or that the results of the development will be as estimated. Delays in the development of our 
reserves, increases in costs to drill and develop our reserves, or decreases in commodity prices will reduce the future net 
revenues of our estimated undeveloped reserves and could result in some projects becoming uneconomical. In addition, 
delays in the development of reserves could force us to reclassify certain of our proved undeveloped reserves as unproved 
reserves. 

We  could  experience  delays  in  the  payment  of  royalties  and  be  unable  to  replace  Operators  that  do  not  make 
required royalty payments, and we may not be able to terminate our leases with defaulting lessees if any of the operators 
on those leases declare bankruptcy. 

A failure on the part of the Operators of our properties to make royalty payments gives us the right to terminate the 
lease and enforce payment obligations under the lease. If we terminate any of our leases, we would seek a replacement 
operator. However, we might not be able to find a replacement operator and, if we did, we might not be able to enter into 
a new lease on favorable terms within a reasonable period of time. In addition, the outgoing operator could be subject to a 
proceeding under Bankruptcy Code, in which case our right to enforce or terminate the lease for any defaults, including 
non-payment,  could be  substantially  delayed  or otherwise  impaired.  In  general,  in  a  proceeding under  the  Bankruptcy 
Code, the bankrupt operator would have substantial time to decide whether to ultimately reject or assume the lease, which 
could prevent the execution of a new lease or the assignment of the existing lease to another operator. In the event that the 
operator rejected the lease, our ability to collect amounts owed would be substantially delayed, and our ultimate recovery 
could be only a fraction of the amount owed or nothing. In addition, if we are able to enter into a new lease with a new 
operator, the replacement operator may not achieve the same levels of production or sell oil or natural gas at the same 
price as the operator it replaced. 

If the operators of our oil & gas properties suspend our right to receive royalty payments due to title or other issues, 

our business, financial condition, and/or results of operations could be adversely affected. 

Upon a change in ownership of mineral interests, and at regular intervals pursuant to routine audit procedures at each 
of the Operators otherwise at its discretion, the operator of the underlying property has the right to investigate and verify 
the title and ownership of mineral interests with respect to the properties it operates. If any title or ownership issues are 
not  resolved  to  its  reasonable  satisfaction  in  accordance  with  customary  industry  standards,  the operator may  suspend 
payment  of  the  related  royalty.  If  an  operator  of  our  properties  is  not  satisfied  with  the  documentation  we  provide  to 

49 

 
 
 
 
 
 
 
 
validate our ownership, it may place our royalty payment in suspense until such issues are resolved, at which time we 
would receive in full payments that would have been made during the suspense period, without interest. Certain of the 
Operators impose significant documentation requirements for title transfer and may keep royalty payments in suspense for 
significant periods of time. During the time that an operator puts our assets in pay suspense, we would not receive the 
applicable mineral or royalty payment owed to us from sales of the underlying oil or natural gas related to such mineral or 
royalty interest. If a significant amount of our royalty interests is placed in suspense, our results of operations could be 
reduced significantly. 

Our estimated oil & gas reserves are based on many assumptions that could turn out to be inaccurate. Any material 
inaccuracies in these reserve estimates or underlying assumptions will materially affect the quantities and present value 
of our reserves. 

Oil & gas reserve engineering is not an exact science and requires subjective estimates of underground accumulations 
of oil & gas and assumptions concerning future oil & gas prices, production levels, ultimate recoveries, and operating 
costs. As a result, estimated quantities of proved reserves and projections of future production rates could be incorrect. 
Our estimates of proved reserves and related valuations as of December 31, 2023, were audited by CGA, which conducted 
a detailed review of all of our properties at that time using the information provided by us. Over time, we may make 
material changes to reserve estimates taking into account the results of actual drilling, testing, and production. In addition, 
certain  assumptions  regarding  future  oil  &  gas  prices,  production  levels,  and operating  costs  could  prove  incorrect.  A 
meaningful portion of our reserve estimates is made without the benefit of lengthy production history, which is less reliable 
than estimates based on lengthy production history. Any significant variance from these assumptions to actual figures 
could greatly affect our estimates of reserves and future cash generated from operations. Numerous changes over time to 
the assumptions on which our reserve estimates are based, as described above, often result in the actual quantities of oil & 
gas that are ultimately recovered being different from our reserve estimates. 

Furthermore, the present value of future net cash flows from our proved reserves is not necessarily the same as the 
current market value of our estimated reserves. In accordance with rules established by the SEC and the FASB, we base 
the estimated discounted future net cash flows from our proved reserves on the twelve-month average oil & gas index 
prices, calculated as the unweighted arithmetic average for the first day-of-the-month price for each month, and costs in 
effect on the date of the estimate, holding the prices and costs constant throughout the life of the properties. Actual future 
prices and costs could differ materially from those used in the present value estimate, and future net present value estimates 
using then-current prices and costs could  be significantly less than the current estimate. In addition, the 10% discount 
factor we use when calculating discounted future net cash flows may not be the most appropriate discount factor based on 
interest rates in effect from time to time and risks associated with us or the oil & gas industry in general. Please see "Item 
2. Properties—Oil & Gas Reserves" for more information on our reserves. 

Drilling for and producing oil & gas are high-risk activities with many uncertainties that could materially adversely 

affect our business, financial condition, and results of operations. 

The drilling activities of the operators of our properties will be subject to many risks. For example, we will not be 
able to assure our unitholders that wells drilled by the operators of our properties will be productive. Drilling for oil & gas 
often involves unprofitable efforts, not only from dry wells but also from wells that are productive but do not produce 
sufficient oil or gas to return a profit at then realized prices after deducting drilling, operating, and other costs. The seismic 
data and other technologies used do not provide conclusive knowledge prior to drilling a well that oil or gas is present or 
that it can be produced economically. The costs of exploration, exploitation, and development activities are subject to 
numerous uncertainties beyond our control and increases in those costs can adversely affect the economics of a project. 
Further, the Operators' drilling and producing operations could be curtailed, delayed, canceled, or otherwise negatively 
impacted as a result of other factors, including: 

50 

 
 
 
 
 
  
• 
• 
• 
• 
• 
• 
• 
• 

unusual or unexpected geological formations or earthquakes; 
loss of drilling fluid circulation;  
title problems; 
facility or equipment malfunctions; 
unexpected operational events; 
shortages or delivery delays of equipment and services; 
compliance with environmental and other governmental requirements; and 
adverse weather conditions. 

Any of these risks can cause substantial losses, including personal injury or loss of life, damage to or destruction of 
property, natural resources, and equipment, pollution, environmental contamination or loss of wells, and other regulatory 
penalties. In the event that planned operations, including the drilling of development wells, are delayed or canceled, or 
existing wells or development wells have lower than anticipated production due to one or more of the factors above or for 
any other reason, our financial condition, results of operations, and free cash flow could be materially adversely affected. 

The marketability of oil & gas production is dependent upon transportation and other facilities, certain of which 
neither  we nor the operators of our properties control. If these facilities are unavailable, the Operators' operations 
could be interrupted and our results of operations and cash available for distribution could be materially adversely 
affected. 

The marketability of the Operators' oil & gas production will depend in part upon the availability, proximity, and 
capacity of transportation facilities, including gathering systems, trucks, and pipelines, owned by third parties. Neither we 
nor, in general, the operators of our properties control these third-party transportation facilities and the Operators' access 
to them may be limited or denied. Insufficient production from the wells on our acreage or a significant disruption in the 
availability  of  third-party  transportation  facilities  or  other  production  facilities  could  adversely  impact  the  Operators' 
ability to deliver to market or produce oil & gas and thereby cause a significant interruption in the Operators' operations. 
If they are unable, for any sustained period, to implement acceptable delivery or transportation arrangements or encounter 
production-related difficulties, they may be required to shut-in or curtail production. In addition, the amount of oil & gas 
that can be produced and sold may be subject to curtailment in certain other circumstances outside of our or the Operators' 
control,  such  as pipeline  interruptions due  to  maintenance, excessive  pressure,  the  inability  of  downstream  processing 
facilities to accept unprocessed gas, physical damage to the gathering system or transportation system or lack of contracted 
capacity on such systems. The curtailments arising from these and similar circumstances could last from a few days to 
several months. In many cases, we and the Operators are provided with limited notice, if any, as to when these curtailments 
will arise and the duration of such curtailments. Any such shut-in or curtailment, or an inability to obtain favorable terms 
for  delivery  of  the  oil  &  gas  produced  from  our  acreage,  could  adversely  affect  our  financial  condition,  results  of 
operations, and cash available for distribution.  

We do not currently enter into hedging arrangements with respect to commodity production from our properties, 

and we will be exposed to the impact of decreases in the price of such commodities. 

We have not entered into hedging arrangements to establish, in advance, a price for the sale of the oil & gas or the 
coal produced from our properties, and we may not enter into such arrangements in the future. As a result, although we 
could realize the benefit of any short-term increase in the price, we will not be protected against decreases in the price or 
prolonged periods of low commodity prices, which could materially adversely affect our business, results of operation and 
cash available for distribution. 

In the future, we may enter into hedging transactions with the intent of reducing volatility in our cash flows due to 
fluctuations in the price of oil & gas or coal. However, these hedging activities may not be as effective as we intend in 
reducing  the  volatility  of  our  cash  flows  and,  if  entered  into,  are  subject  to  the  risks  that  the  terms  of  the  derivative 
instruments will be imperfect, a counterparty may not perform its obligations under a derivative contract, there could be a 
change in the expected differential between the underlying commodity price in the derivative instrument and the actual 
price received, our hedging policies and procedures may not be properly followed and the steps we take to monitor our 
derivative financial instruments may not detect and prevent violations of our risk management policies and procedures, 
particularly if deception or other intentional misconduct is involved. Further, we could  be limited in receiving the full 
benefit of increases in commodity prices as a result of these hedging transactions. The occurrence of any of these risks 
could prevent us from realizing the benefit of a derivative contract. 

51 

 
 
 
 
 
 
 
Expansions and acquisitions involve a number of risks, any of which could cause us not to realize the anticipated 

benefits. 

Since our formation and the acquisition of our predecessor in August 1999, we have expanded our coal operations by 
adding and developing mines in existing, adjacent, and neighboring properties. Similarly, the profitability of our business 
depends significantly upon acquisitions to grow our coal and oil & gas reserves, production, and free cash flow. Our future 
growth could be limited if we are unable to continue to make acquisitions in either our coal operations or our royalties 
segments, or if we are unable to successfully integrate the companies, businesses, or properties we acquire. We may not 
be successful in consummating any acquisitions and the consequences of undertaking these acquisitions are unknown. 

Competition for acquisitions of coal and oil & gas mineral interests could increase the cost of, or cause us to refrain 
from, completing acquisitions. Our ability to complete acquisitions is dependent upon, among other things, our ability to 
obtain debt and equity financing under acceptable terms. In addition, these acquisitions could be in geographic regions in 
which  we  do  not  currently  hold  properties,  which  could  subject  us  to  additional  and  unfamiliar  legal  and  regulatory 
requirements.  No  assurance  can  be  given  that  we  will  be  able  to  identify  suitable  acquisition  opportunities,  negotiate 
acceptable terms, obtain financing for acquisitions on acceptable terms, or successfully acquire identified targets. 

The process of integrating acquired assets could involve unforeseen difficulties and could require a disproportionate 
amount of our managerial and financial resources. If we are unable to successfully integrate the companies, businesses, or 
properties we acquire, our profitability could decline and we could experience a material adverse effect on our business, 
financial  condition,  or  results  of  operations.  Expansion  and  acquisition  transactions  involve  various  inherent  risks, 
including: 

• 

• 

• 

• 
• 

uncertainties  in  assessing  the  value,  strengths,  and  potential  profitability  of  expansion  and  acquisition 
opportunities; 
uncertainties in identifying the extent of all weaknesses, risks, contingent and other liabilities of, expansion and 
acquisition opportunities; 
the ability to achieve identified operating and financial synergies anticipated to result from an expansion or an 
acquisition; 
problems that could arise from the integration of the new operations; and 
unanticipated  changes  in  business,  industry,  or  general  economic  conditions  that  affect  the  assumptions 
underlying our rationale for pursuing the expansion or acquisition opportunity. 

Any one or more of these factors could cause us not to realize the benefits anticipated to result from an expansion or 
acquisition.  Any  expansion  or  acquisition  opportunities  we  pursue  could  materially  affect  our  liquidity  and  capital 
resources and could require us to incur indebtedness, seek equity capital, or both. Future expansions or acquisitions could 
result in us assuming more long-term liabilities relative to the value of the acquired assets than we have assumed in our 
previous expansions and/or acquisitions. 

The integration of any expansions or acquisitions that we complete will be subject to substantial risks. 

Even if we make expansions or acquisitions that we believe will increase our coal or mineral revenue, any expansion 

or acquisition involves potential risks, including, among other things: 

• 

• 

• 
• 

the  validity  of  our  assumptions  about  estimated  proved  reserves,  future  production,  prices,  revenues,  capital 
expenditures, the operating expenses, and costs the Operators would incur to develop the minerals; 
a decrease in our liquidity by using a significant portion of our cash generated from operations or borrowing 
capacity to finance acquisitions; 
a significant increase in our interest expense or financial leverage if we incur debt to finance acquisitions; 
the  assumption  of  unknown  liabilities,  losses  or  costs  for  which  we  are  not  indemnified  or  for  which  any 
indemnity we receive is inadequate; 

•  mistaken assumptions about the overall cost of equity or debt; 
• 
our ability to obtain satisfactory title to the assets we acquire; 
• 
an inability to hire, train or retain qualified personnel to manage and operate our growing mineral assets; and 
• 
the occurrence of other significant changes, such as impairment of properties, goodwill or other intangible assets, 
asset devaluation, or restructuring charges. 

52 

 
 
 
 
 
 
 
 
We  may  not  be  able  to  effectively  identify  investment  opportunities  in  the  advancement  of  energy  and  related 

infrastructure on favorable terms, or at all, and failure to do so may limit our future growth.  

Part of our strategy includes positioning ourselves as a reliable energy provider for the future by pursuing strategic 
investments that leverage our core competencies and relationships with electric utilities, industrial customers, and federal 
and state governments. This strategy depends on our ability to successfully identify and evaluate investment opportunities. 
The number of opportunities may be limited, and we will compete with other investors for these limited opportunities, 
which could make them more expensive and the returns for our investments less attractive and possibly cause us to refrain 
from making them at all. Further, certain opportunities will depend on technological and other advancements that may not 
be within our control and may not come to fruition or be economically feasible in the near term, and we may fail to realize 
the  anticipated  benefit  of  our  investments.  Any  new  opportunities  also  may  depend  on  the  viability  of  new  assets  or 
businesses  that  are  contingent  on  public  policy  mechanisms  including  investment  tax  credits,  subsidies,  renewable 
portfolio standards and carbon trading plans. These mechanisms have been implemented at the state and federal levels to 
support the development of renewable energy, demand-side, and other infrastructure technologies. The availability and 
continuation of public policy support mechanisms will drive a significant part of the economics and viability of investments 
generally, as well as our participation in them. 

Our  inability  to  obtain  commercial  insurance  at  acceptable  rates  or  our  failure  to  adequately  reserve  for  self-

insured exposures could increase our expenses and have a negative impact on our business. 

We  believe  that  commercial  insurance  coverage  is  prudent  in  certain  areas  of  our  business  for  risk  management. 
Insurance  costs  could  increase  substantially  in  the  future and  could  be  affected  by  natural  disasters,  fear  of  terrorism, 
financial  irregularities,  cybersecurity  breaches  and  other  fraud  at  publicly-traded  companies,  intervention  by  the 
government,  an  increase  in  the  number  of  claims  received  by  the  carriers,  and  a  decrease  in  the  number  of  insurance 
carriers. In addition, the carriers with which we hold our policies could go out of business or be otherwise unable to fulfill 
their contractual obligations or could disagree with our interpretation of the coverage or the amounts owed. In addition, 
for  certain  types  or  levels  of  risk,  such  as  risks  associated  with  certain  natural  disasters  or  terrorist  attacks,  we  may 
determine that we cannot obtain commercial insurance at acceptable rates, if at all. Therefore, we may choose to forego or 
limit our purchase of relevant commercial insurance, choosing instead to self-insure one or more types or levels of risks. 
If we suffer a substantial loss that is not covered by commercial insurance or our self-insurance reserves, the loss and 
related  expenses  could harm our  business  and  operating  results.  Also,  exposures  exist  for  which no  insurance  may  be 
available  and  for  which  we  have  not  reserved.  In  addition,  environmental  activists  could  try  to  hamper  fossil-fuel 
companies by other means including pressuring insurance and surety companies into restricting access to certain needed 
coverages. 

Tax Risks to Our Common Unitholders 

Our tax treatment depends on our status as a partnership for U.S. federal income tax purposes, and our not being 
subject to a material amount of entity-level taxation. If the IRS were to treat us as a corporation for U.S. federal income 
tax purposes, or we become subject to entity-level taxation for state tax purposes, our cash available for distribution to 
you would be substantially reduced. 

The anticipated after-tax benefit of an investment in our common units depends largely on our being treated as a 

partnership for U.S. federal income tax purposes. 

Even though we are organized as a limited partnership under Delaware law, we would be treated as a corporation for 
U.S. federal income tax purposes unless we satisfy a "qualifying income" requirement. Based on our current operations 
and  current  Treasury  Regulations,  we  believe  we  satisfy  the  qualifying  income  requirement.  However,  we  have  not 
requested, and do not plan to request, a ruling from the IRS on this or any other matter affecting us. Failing to meet the 
qualifying income requirement or a change in current law could cause us to be treated as a corporation for U.S. federal 
income tax purposes or otherwise subject us to taxation as an entity. 

If we were treated as a corporation for U.S. federal income tax purposes, we would pay U.S. federal income tax on 
our taxable income at the corporate tax rate, and would likely be liable for state income tax at varying rates. Distributions 
to our unitholders would generally be taxed again as corporate distributions, and no income, gains, losses, deductions, or 
credits would flow through to our unitholders. Because taxes would be imposed upon us as a corporation, our cash available 

53 

 
 
 
 
 
 
 
 
 
for distribution to our unitholders would be substantially reduced. Therefore, our treatment as a corporation would result 
in a material reduction in the anticipated cash flow and after-tax return to our unitholders, likely causing a substantial 
reduction in the value of our common units. 

At the state level, several states have been evaluating ways to subject partnerships to entity-level taxation through the 
imposition of state income, franchise, or other forms of taxation. If any state were to impose a tax upon us as an entity, the 
cash available for distribution to you would be reduced and the value of our units could be negatively impacted. 

The  tax  treatment  of  publicly  traded  partnerships  or  an  investment  in  our  units  could  be  subject  to  potential 

legislative, judicial or administrative changes or differing interpretations, possibly applied on a retroactive basis. 

The present U.S. federal income tax treatment of publicly traded partnerships, including us, or an investment in our 
common units may be modified by administrative, legislative or judicial changes or differing interpretations at any time. 
Members of Congress have frequently proposed and considered substantive changes to the existing U.S. federal income 
tax laws that would affect publicly traded partnerships, including proposals that would eliminate our ability to qualify for 
partnership  tax  treatment.    Recent  proposals  have  provided  for  the  expansion  of  the  qualifying  income  exception  for 
publicly traded partnerships in certain circumstances and other proposals have provided for the total elimination of the 
qualifying income exception upon which we rely for our partnership tax treatment.  In addition, the Treasury Department 
has issued, and in the future may issue, regulations interpreting those laws that affect publicly traded partnerships. There 
can be no assurance that there will not be further changes to U.S. federal income tax laws or the Treasury Department's 
interpretation of the qualifying income rules in a manner that could impact our ability to qualify as a partnership in the 
future. 

Any  modification  to  the  U.S.  federal  income  tax  laws  and  the  interpretations  thereof  may  or  may  not  be  applied 
retroactively  and  could  make  it  more  difficult  or  impossible  for  us  to  meet  the  exception  for  certain  publicly  traded 
partnerships to be treated as partnerships for U.S. federal income tax purposes.  We are unable to predict whether any 
changes or other proposals will ultimately be enacted. Any similar or future legislative changes could negatively impact 
the value of an investment in our common units.  You are urged to consult with your own tax advisor with respect to the 
status of regulatory or administrative developments and proposals and their potential effect on your investment in our 
common units. 

If the IRS were to contest the U.S. federal income tax positions we take, it may adversely impact the market for our 

common units, and the costs of any such contest would reduce cash available for distribution to our unitholders.   

We have not requested a ruling from the IRS with respect to our treatment as a partnership for U.S. federal income 
tax purposes.  The IRS may adopt positions that differ from the positions that we take. It may be necessary to resort to 
administrative or court proceedings to sustain some or all of the positions we take.  A court may not agree with some or 
all of the positions we take.  Any contest with the IRS may materially and adversely impact the market for our common 
units and the price at which they trade.  Moreover, the costs of any contest between us and the IRS will result in a reduction 
in our cash available for distribution to our unitholders and thus will be borne indirectly by our unitholders. 

If the IRS makes audit adjustments to our income tax returns for tax years beginning after December 31, 2017, it 
(and some states) may assess and collect any taxes (including any applicable penalties and interest) resulting from such 
audit adjustments directly from us, in which case our cash available for distribution to our unitholders could be reduced 
and  our  current  and  former  unitholders  may  be  required  to  indemnify  us  for  any  taxes  (including  any  applicable 
penalties and interest) resulting from such audit adjustments that were paid on such unitholders' behalf.   

Pursuant to the Bipartisan Budget Act of 2015, for tax years beginning after December 31, 2017, if the IRS makes 
audit adjustments to our income tax returns, it (and some states) may assess and collect any taxes (including any applicable 
penalties and interest) resulting from such audit adjustments directly from us. To the extent possible under these rules, our 
general partner may elect to either pay the taxes (including any applicable penalties and interest) directly to the IRS or, if 
we are eligible, issue a revised information statement to each unitholder and former unitholder with respect to an audited 
and adjusted return. Although our general partner may elect to have our unitholders and former unitholders take such audit 
adjustment into account and pay any resulting taxes (including applicable penalties and interest) in accordance with their 
interests in us during the tax year under audit, there can be no assurance that such election will be practical, permissible or 
effective in all circumstances. As a result, our current unitholders may bear some or all of the tax liability resulting from 
such audit adjustment, even if such unitholders did not own units in us during the tax year under audit. If, as a result of 

54 

 
 
 
 
 
 
 
 
any such audit adjustment, we are required to pay taxes, penalties and interest, our cash available for distribution to our 
unitholders might be substantially reduced and our current and former unitholders may be required to indemnify us for 
any taxes (including any applicable penalties and interest) resulting from such audit adjustments that were paid on such 
unitholders' behalf. These rules are not applicable for tax years beginning on or prior to December 31, 2017. 

Our  unitholders  are  required  to  pay  taxes  on  their  share  of  our  income  even  if  they  do  not  receive  any  cash 

distributions from us. 

Our unitholders are required to pay any U.S. federal income taxes and, in some cases, state and local income taxes, 
on  their  share of our  taxable income  whether or not  they  receive  cash  distributions  from  us.  Our  unitholders may not 
receive cash distributions from us equal to their share of our taxable income or even equal to the actual tax liability that 
results from that income. 

Tax gain or loss on the disposition of our common units could be more or less than expected. 

If a unitholder sells units, the unitholder will recognize a gain or loss equal to the difference between the amount 
realized and that unitholder's tax basis in those common units. Because distributions in excess of a unitholder's allocable 
share of our net taxable income decrease such unitholder's tax basis in its units, the amount, if any, of such prior excess 
distributions with respect to the units a unitholder sells will, in effect, become taxable income to a unitholder if it sells 
such units at a price greater than its tax basis in those units, even if the price such unitholder receives is less than its original 
cost. In addition, because the amount realized includes a unitholder's share of our nonrecourse liabilities, if a unitholder 
sells its units, a unitholder may incur a tax liability in excess of the amount of cash received from the sale. 

A substantial portion of the amount realized from a unitholder's sale of our units, whether or not representing gain, 
may be taxed as ordinary income to such unitholder due to potential recapture items, including depreciation recapture. 
Thus, a unitholder may recognize both ordinary income and capital loss from the sale of units if the amount realized on a 
sale of such units is less than such unitholder's adjusted basis in the units. Net capital loss may only offset capital gains 
and, in the case of individuals, up to $3,000 of ordinary income per year. In the taxable period in which a unitholder sells 
its units, such unitholder may recognize ordinary income from our allocations of income and gain to such unitholder prior 
to the sale and from recapture items that generally cannot be offset by any capital loss recognized upon the sale of units. 

Unitholders may be subject to limitation on their ability to deduct interest expense incurred by us.  

In general, we are entitled to a deduction for interest paid or accrued on indebtedness properly allocable to our trade 
or business during our taxable year. However, our deduction for "business interest" is limited to the sum of our business 
interest income and 30% of our "adjusted taxable income." For the purposes of this limitation, our adjusted taxable income 
is computed without regard to any business interest expense or business interest income. If our "business interest" is subject 
to limitation under these rules, our unitholders will be limited in their ability to deduct their share of any interest expense 
that has been allocated to them. As a result, unitholders may be subject to limitation on their ability to deduct interest 
expense incurred by us. 

Tax-exempt  entities  face  unique  tax  issues  from  owning  our  common  units  that  may  result  in  adverse  tax 

consequences to them. 

Investment in our common units by tax-exempt entities, such as employee benefit plans and IRAs raises issues unique 
to them. For example, virtually all of our income allocated to organizations that are exempt from U.S. federal income tax, 
including  IRAs  and  other  retirement  plans,  will  be  unrelated  business  taxable  income  and  will  be  taxable  to  them. 
Additionally, all or part of any gain recognized by such tax-exempt organization upon a sale or other disposition of our 
units may be unrelated business taxable income and may be taxable to them. Tax-exempt entities should consult a tax 
advisor before investing in our common units. 

Non-U.S. unitholders  will be subject to U.S. taxes and withholding with respect to their income and gain from 

owning our units.  

Non-U.S. unitholders are generally taxed and subject to income tax filing requirements by the United States on income 
effectively connected with a U.S. trade or business. Income allocated to our unitholders and any gain from the sale of our 
units will generally be considered to be "effectively connected" with a U.S. trade or business.  As a result, distributions to 

55 

 
 
 
 
 
 
 
 
 
 
 
a non-U.S. unitholder will be subject to withholding at the highest applicable effective tax rate and a non-U.S. unitholder 
who sells or otherwise disposes of a unit will also be subject to U.S. federal income tax on the gain realized from the sale 
or disposition of that unit. In addition to the withholding tax imposed on distributions of effectively connected income, 
distributions to a non-U.S. unitholder will also be subject to a 10% withholding tax on the amount of any distribution in 
excess of our cumulative net income. As we do not compute our cumulative net income for such purposes due to the 
complexity of the calculation and lack of clarity in how it would apply to us, we intend to treat all of our distributions as 
being in excess of our cumulative net income for such purposes and subject to such 10% withholding tax.  Accordingly, 
distributions to a non-U.S. unitholder will be subject to a combined withholding tax rate equal to the sum of the highest 
applicable effective tax rate and 10%. 

Moreover, the transferee of an interest in a partnership that is engaged in a U.S. trade or business is generally required 
to withhold 10% of the "amount realized" by the transferor unless the transferor certifies that it is not a foreign person. 
While  the  determination  of  a  partner's  "amount  realized"  generally  includes  any  decrease  of  a  partner's  share  of  the 
partnership's liabilities, the Treasury regulations provide that the "amount realized" on a transfer of an interest in a publicly 
traded partnership, such as our common units, will generally be the amount of gross proceeds paid to the broker effecting 
the  applicable  transfer  on  behalf  of  the  transferor,  and  thus  will  be  determined  without  regard  to  any decrease  in  that 
partner's share of a publicly traded partnership's liabilities. For a transfer of interests in a publicly traded partnership that 
is effected through a broker on or after January 1, 2023, the obligation to withhold is imposed on the transferor's broker.  
Current and prospective non-U.S. unitholders should consult their tax advisors regarding the impact of these rules on an 
investment in our common units.  

We treat each purchaser of our common units as having the same tax benefits without regard to the common units 
actually purchased. The IRS may challenge this treatment, which could adversely affect the value of our common units. 

Because we cannot match transferors and transferees of common units, we have adopted certain methods for allocating 
depreciation  and  amortization  deductions  that  may  not  conform  to  all  aspects  of  existing  Treasury  Regulations.  A 
successful IRS challenge to the use of these methods could adversely affect the amount of tax benefits available to our 
unitholders. It also could affect the timing of these tax benefits or the amount of gain from any sale of common units and 
could have a negative impact on the value of our units or result in audit adjustments to a unitholder's tax returns. 

We generally prorate our items of income, gain, loss and deduction between transferors and transferees of our 
units each month based on the ownership of our units on the first day of each month, instead of on the basis of the date 
a particular unit is transferred.  The IRS may challenge this treatment, which could change the allocation of items of 
income, gain, loss and deduction among our unitholders. 

We generally prorate our items of income, gain, loss and deduction between transferors and transferees of our units 
each  month  based on  the  ownership  of  our  units  on  the first  day  of  each  month,  instead  of on  the  basis  of  the  date a 
particular unit is transferred.  Similarly, we generally allocate (i) certain deductions for depreciation of capital additions, 
(ii) gain or loss realized on a sale or other disposition of our assets, and (iii) in the discretion of the general partner, any 
other  extraordinary  item  of  income,  gain,  loss  or  deduction  based  on  ownership  on  the  Allocation  Date.  Treasury 
Regulations allow a similar monthly simplifying convention, but such regulations do not specifically authorize all aspects 
of our proration method.  If the IRS were to challenge our proration method, we may be required to change the allocation 
of items of income, gain, loss and deduction among our unitholders. 

A unitholder whose units are the subject of a securities loan (e.g., a loan to a "short seller" to cover a short sale of 
units) may be considered as having disposed of those units. If so, such unitholder would no longer be treated for tax 
purposes as a partner with respect to those units during the period of the loan and may recognize gain or loss from the 
disposition. 

Because  there  are  no  specific  rules  governing  the  U.S.  federal  income  tax  consequence  of  loaning  a  partnership 
interest, a unitholder whose units are the subject of a securities loan may be considered as having disposed of the loaned 
units.  In that case, the unitholder may no longer be treated for tax purposes as a partner with respect to those units during 
the period of the loan to the short seller and the unitholder may recognize gain or loss from such disposition.  Moreover, 
during the period of the loan, any of our income, gain, loss or deduction with respect to those units may not be reportable 
by the unitholder and any cash distributions received by the unitholder as to those units could be fully taxable as ordinary 
income.  Unitholders desiring to assure their status as partners and avoid the risk of gain recognition from a securities loan 

56 

 
 
 
 
 
 
 
are  urged  to  consult  a  tax  advisor  to  determine  whether  it  is  advisable  to  modify  any  applicable  brokerage  account 
agreements to prohibit their brokers from borrowing their units. 

Certain U.S. federal income tax deductions currently available with respect to coal mining and production may be 

eliminated as a result of future legislation. 

In past years, members of the U.S. Congress have indicated a desire to eliminate certain key U.S. federal income tax 
provisions  currently  applicable  to  coal  companies,  including  the  percentage  depletion  allowance  with  respect  to  coal 
properties.  Elimination of those provisions would not impact our financial statements or results of operations.  However, 
elimination of such provisions could result in unfavorable tax consequences for our unitholders and, as a result, could 
negatively impact our unit price. 

Our  unitholders  will  likely  be  subject  to  state  and  local  taxes  and  income  tax  return  filing  requirements  in 

jurisdictions where they do not live as a result of investing in our common units. 

In addition to U.S. federal income taxes, our unitholders may be subject to other taxes, such as state and local income 
taxes, unincorporated business taxes and estate, inheritance or intangible taxes that are imposed by the various jurisdictions 
in which we conduct business or own property now or in the future, even if they do not live in any of those jurisdictions. 
Our unitholders will likely be required to file state and local income tax returns and pay state and local income taxes in 
some or all of these various jurisdictions. Further, our unitholders may be subject to penalties for failure to comply with 
those requirements. 

We  currently  own  assets  and  conduct  business  in  multiple  states  that  currently  impose  a  personal  income  tax  on 
individuals,  corporations  and  other  entities.  As  we  make  acquisitions  or  expand  our  business,  we  may  own  assets  or 
conduct business in additional states that impose a personal income tax. It is our unitholders' responsibility to file all U.S. 
federal, foreign, state, and local tax returns and pay any taxes due in these jurisdictions.  Unitholders should consult with 
their own tax advisors regarding the filing of such tax returns, the payment of such taxes, and the deductibility of any taxes 
paid.

CYBERSECURITY 

Description of Processes for Assessing, Identifying, and Managing Cybersecurity Risks 

We  operate  in  an  increasingly  interconnected  digital  landscape  and  we  recognize  the  importance  of  assessing, 
identifying, and managing material risks from cybersecurity threats. In the normal course of business, we may collect and 
store  certain  sensitive  information,  including  proprietary  and  confidential  business  information,  intellectual  property, 
sensitive third-party information, employee information and personal information. We rely on information systems for the 
management of this information in addition to our management of business processes including inventory, payment of 
obligations, collection of cash, human capital management, financial tools and other processes and procedures. Our ability 
to manage our business effectively depends on the reliability and capacity of these systems. We seek to address these risks 
by safeguarding assets, data, and operations through the cybersecurity risk management processes described below: 

Risk Assessment: 

Regular assessments are conducted across our systems, networks, and data infrastructure to identify potential 
cybersecurity threats and vulnerabilities. These assessments include penetration testing, vulnerability scanning, 
and red teaming exercises conducted by third-party service providers, which help us to evaluate the likelihood 
and potential impact of cybersecurity incidents. Feedback from these assessments is incorporated into our systems 
and procedures through upgrades intended to further improve our security posture. 

57 

 
 
 
 
 
 
 
 
 
 
 
 
 
Incident Identification and Response: 

A  monitoring  and  detection  system  has  been  implemented  to  help  identify  cybersecurity  incidents.  The  IT 
Security Department is tasked with monitoring certain network activities, logs, and system behavior, leveraging 
threat detection technologies. In the event of any breach or cybersecurity incident, we have an incident response 
plan that is designed to follow industry best practices and aligns with legal and regulatory requirements. This plan 
is  designed  to  provide  for  immediate  action  to  contain  the  incident,  mitigate  the  impact,  and  restore  normal 
operations efficiently. 

Cybersecurity Training and Awareness: 

Cybersecurity  awareness  among  our  employees  is  promoted  with  regular  training  and  awareness  programs. 
Employees receive training on recognizing and reporting potential cybersecurity threats, best practices for data 
protection,  and  adhering  to  cybersecurity  policies  and  procedures.  Additionally,  periodic  simulated  phishing 
exercises are conducted to enhance employee readiness in identifying and mitigating phishing attacks. 

Access Controls: 

Access control policies have been implemented to limit unauthorized access to sensitive information and we seek 
to maintain and monitor critical systems. Multi-factor authentication is used for remote access, use of privileged 
accounts and access to critical systems. 

Encryption and Data Protection: 

Encryption  methods  are  used  to  protect  sensitive  data  in  transit  and  at  rest.  This  includes  the  encryption  of 
customer data, financial information, and other confidential data. 

The above cybersecurity risk management processes are integrated into the Partnership's overall risk management 
program. Cybersecurity threats are understood to be dynamic and intersect with various other enterprise risks. As such, 
cybersecurity  is  considered  as  an  important  component  of  our  enterprise-wide  risk  management  approach.  We  have 
assembled  a  Cybersecurity  Steering  Committee  comprised  of  IT  management,  cybersecurity  specialists,  and 
representatives  of  business  management,  including  the  CTO  and  internal  legal  counsel.    The  Cybersecurity  Steering 
Committee reviews information security policies and cybersecurity risks in conjunction with other operational, financial, 
and  strategic risks  to  ensure alignment  with  our  business  objectives.  The  Cybersecurity  Steering  Committee  convenes 
regularly to review and monitor the Partnership’s programs for the prevention, detection, mitigation, and remediation of 
cybersecurity incidents. The Cybersecurity Steering Committee receives reports on security incidents, threat intelligence, 
and vulnerability assessments from our IT Security Department. 

The  Cybersecurity  Steering  Committee  regularly  reports  to  the  CFO  through  the  CTO  and  reports  annually  on 
cybersecurity to the Audit Committee during a scheduled meeting. These reports include, as appropriate, updates on the 
current  cybersecurity  landscape,  incident  trends,  and  any  significant  developments  that  may  impact  the  Partnership's 
security posture.  

To enhance the effectiveness of our cybersecurity program, we periodically engage external assessors, consultants, 
and auditors. These third-party service providers conduct independent evaluations of our cybersecurity measures, helping 
to identify areas for improvement and adherence to industry standards and best practices. 

Our IT Security Department recognizes that third-party service providers may introduce cybersecurity risks to our 
organization.  In  an  effort  to  mitigate  these  risks,  we  have  implemented  a  process  designed  to  assess  and  oversee  the 
cybersecurity practices of our vendors. Before engaging with any third-party cybersecurity service provider, we conduct 
due  diligence  to  evaluate  their  cybersecurity  capabilities.  Additionally,  we  include  cybersecurity  requirements  in  our 
contracts with these providers, requiring them to adhere to certain cybersecurity standards and protocols. 

Impact of Risks from Cybersecurity Threats 

During  2023  and  through  the  date  of  this  Annual  Report  on  Form  10-K,  though  the  Partnership  and  our  service 
providers may have experienced cybersecurity incidents, we are not aware of any cybersecurity threats, including as a 

58 

 
 
 
 
 
 
 
 
 
 
 
 
 
result of any previous cybersecurity incidents, that have materially affected or are reasonably likely to materially affect 
the Partnership, including our business strategy, result of operations, or financial condition. However, we acknowledge 
that cybersecurity threats are continually evolving, and the possibility of future cybersecurity incidents remains. Our IT 
Security  Department  aims  to monitor  and  assess  these  risks  to  maintain  the  security  and  continuity  of  our  operations. 
Despite  the  implementation  of  our  cybersecurity  programs,  our  security  measures  cannot  guarantee  that  a  significant 
cyberattack will not occur. A successful attack on our IT systems could have significant consequences to our business. 
While we devote resources to our security measures to protect our systems and information, these measures cannot provide 
absolute security. Please see "Item 1A. Risk Factors" for additional information about the risks to our business associated 
with a breach or compromise to our information technology systems. 

Board of Directors' Oversight of Risks from Cybersecurity Threats 

The Board of Directors oversees risks from cybersecurity threats. Recognizing the importance of cybersecurity to the 
success  and  resilience  of  our  business,  the  Board  considers  cybersecurity  to  be  an  important  aspect  of  corporate 
governance.  To  facilitate  effective  oversight,  the  Audit  Committee  and  the  Board  of  Directors  hold  discussions  with 
management, including the CTO on cybersecurity risks, incident trends, and the effectiveness of cybersecurity measures 
annually and as needed during both scheduled and special meetings.  If new material cybersecurity risks arise, the Board 
of Directors and the Audit Committee are informed through regular discussions between the CFO and both the Chairman 
of the Board and the Audit Committee Chair. These discussions are then brought to the attention of the Board of Directors 
and Audit Committee at the next meeting. 

Management's Role and Expertise 

The CTO and the Cybersecurity Steering Committee are responsible for overseeing and executing our cybersecurity 
strategy,  including  the  assessment  and  management  of  cybersecurity  risks.  The  CTO  reports  directly  to  the  CFO  and 
maintains communication with the Audit Committee, the Board of Directors and the Cybersecurity Steering Committee 
with respect to information security and cybersecurity matters. 

The CTO holds a Master of Business Administration from the University of Kentucky/University of Louisville's joint 
executive program and has an extensive background in information security, risk management, and incident response with 
over  twenty  years  of  varying  information  technology  roles  with  increasing  responsibility  at  both  private  and  public 
companies. The CTO is supported by a dedicated team of cybersecurity professionals, each bringing diverse expertise in 
areas such as network security, data protection, and threat intelligence.

PROPERTIES 

COAL MINERAL RESOURCES AND RESERVES 

Overview of Coal Properties  

Our coal properties are located in the Illinois Basin and the Appalachia Basin. Our Illinois Basin properties are located 
in western Kentucky, southern Illinois, and southern Indiana. Our Appalachian properties are located in eastern Kentucky, 
Maryland,  western  Pennsylvania,  and  northern  West  Virginia.  Mining  operations  on  our  coal  properties  consist  of 
underground  mines  that  produce  bituminous  coal  that  is  sold  to  customers  principally  for  electric  power  generation 
(thermal) and the production of steel (metallurgical).  In addition to our coal mining operations, we also hold coal mineral 
interests  that  we  lease/sublease  to our  operations or  hold  for  lease/sublease  to our  operations  or  others.  For  a detailed 
overview  of  our  coal  mining  operations  and  our  coal  royalty  activities,  please  see  "Item  1.  Business—Coal  Mining 
Operations" and "Item 1. Business—Mineral Interest Activities", respectively.  

Evaluation and Review of Coal Mineral Resources and Reserves 

Numerous uncertainties are inherent in estimating coal mineral resources and reserves, and the estimates are subject 
to  change  as  additional  information  becomes  available  or  circumstances  change.    Significant  factors  and  assumptions 
related to the uncertainty in estimating coal mineral reserves and resources include: 

• 

• 
• 
• 
• 
• 

geological and mining conditions, which may not be fully identified by available exploration data and/or 
differ from our experiences in areas where we currently mine; 
the percentage of coal in the ground ultimately recoverable; 
historical production from the area compared with production from other producing areas; 
the assumed effects of regulation and taxes by governmental agencies;  
future improvements in mining technology; and 
assumptions concerning future coal prices, operating costs, capital expenditures, severance and excise taxes, 
and development and reclamation costs. 

Each of the factors which impacts reserve and resource estimation may vary considerably from the assumptions used 
in making the estimation and, as a result, the estimates in this report may not accurately reflect the actual coal reserves and 
resources.    Actual  production,  revenues  and  expenditures  with  respect  to  the  coal  reserves  will  likely  vary  from  the 
assumptions used in these estimates, and these variances may be material.  Government regulations and other pressures 
may result in the closure of coal-fired electric generating plants earlier than assumed.  Such changes would reduce the 
economic viability of our mining operations and could have a material adverse impact on our operations and financial 
results.  

Under SEC rules, a mineral resource is a concentration or occurrence of material of economic interest in or on the 
Earth's crust in such form, grade or quality, and quantity that there are reasonable prospects for economic extraction. A 
mineral resource is a reasonable estimate of mineralization, taking into account relevant factors such as cut-off grade, 
likely mining dimensions, location or continuity that, with the assumed and justifiable technical and economic conditions, 
is likely to, in whole or in part, become economically extractable.  A mineral reserve is an estimate of tonnage and grade 
or quality of indicated and measured mineral resources that, in the opinion of the qualified person, can be the basis of an 
economically viable project. More specifically, it is the economically mineable part of a measured or indicated mineral 
resource,  which  includes  diluting  materials  and  allowances  for  losses  that  may  occur  when  the  material  is  mined  or 
extracted.   

The coal mineral resource and reserve estimates included in this Annual Report on Form 10-K were prepared by an 
independent, qualified engineering firm, RESPEC.  We provided RESPEC with property control, mine plans, production, 
revenue, costs, capital, and other information considered by RESPEC in making their estimates.  As part of our internal 
controls, our geologists and engineers review the integrity, accuracy, and timeliness of the data provided to RESPEC that 
they considered in calculating their coal mineral resource and reserve estimates.  We also review the geologic data, mining 
assumptions, and methodology used by RESPEC to estimate our coal mineral resources and reserves.  Our geologists and 
engineers also met with RESPEC periodically during the year to discuss the assumptions and methods used in the coal 
mineral resource and reserve estimation process.  

60 

 
 
 
 
 
 
 
 
 
 
RESPEC, an independent third-party engineering firm, does not own an interest in any of our properties and is not 
employed on a contingent basis. RESPEC prepared the initial TRS for each of our material mining properties.  The TRSs 
will be updated when there are material changes to the coal mineral reserve or resource estimates.  The most recent TRSs 
for our material mining operations are included as exhibits to our Annual Report on Form 10-K. 

Summary of Coal Mineral Resources and Reserves 

Coal Mineral Resources 

Most of our coal properties designated as mineral resources are of thickness, quality, and mineability similar to that 
of the mineral reserves, and all are proximal to existing infrastructure such as power, water, transportation, facilities, etc.  
However, we have not completed pre-feasibility or feasibility studies with respect to our coal properties designated as 
mineral resources, as is required to convert the mineral resources into mineral reserves. There is no certainty that all or 
any part of the mineral resources will be converted into mineral reserves.

(1)  Combined resources are defined as measured plus indicated resources. 

At December 31, 2023, we had approximately 1.065 billion tons of coal mineral resources.  Tonnages are reported on 
a clean recoverable basis with average long-term pricing based on available third-party forecasts and historical pricing 
adjusted for quality at the end of 2023 in a range from approximately $53 to $59 per short ton in the Illinois Basin and 
from approximately $62 to $119 per short ton in the Appalachian Basin, which are the prices used by RESPEC to estimate 
the amount of coal mineral resources.  Coal sales prices vary based on coal quality, access to transportation, and other 
factors at each location.  All resources are classified as underground mineable in the exploration stage.     

Coal Mineral Reserves 

Reserves are assigned to our active operations and are (1) currently in production, (2) economically viable, and (3) 

meet the other requirements to be considered reserves as defined by the SEC.

Henderson/Union Resources 

The  Henderson/Union  Resources  are  located  in  Henderson  and  Union  counties,  Kentucky  at  37°44'30"N,  -
87°46'07"W  and  we  currently  have  control  in  over  1,600  tracts  encompassing  over  127,000  acres.  The  property  is 
controlled  through  both  fee  ownership  and  leases  of  the  coal.    The  coal  mineral  resources  are  controlled  by  Alliance 
Resource Properties. The base leases are with private owners and WKY CoalPlay or its subsidiaries, which are related 
parties.  See "Item 8. Financial Statements and Supplementary Data—Note 20 – Related-Party Transactions" for more 
information about our WKY CoalPlay transactions.  These base leases generally provide for a term that can be extended 
until exhaustion of the leased coal.  Local infrastructure is as follows:

Description  

The potential underground mine(s) would utilize room-and-pillar methods operating a heavy media, float/sink style 
preparation plant.  Exploration continues as needed to fulfill possible permitting and development requirements.  Multiple 
access  points  are  available  for  development.    Access  is  available  from  the  active  River  View  complex,  which  began 
production in 2009.  All equipment, facilities, infrastructure, and underground development are in good working order and 
maintained  to  industry  standards.    Access  at  the  Hamilton  and  UC  Coal,  LLC  sites  are  considered  "brownfield" 
developments. Though some facilities and permitting are in place, significant upgrades to existing infrastructure and new 
construction would be needed to bring them into good working order that meets industry standards. The property associated 
with Henderson/Union has no book value as of December 31, 2023 but does have outstanding advanced royalties with 
WKY CoalPlay or its subsidiaries.  See "Item 8. Financial Statements and Supplementary Data—Note 20 – Related-Party 
Transactions" for more information about advanced royalties that Henderson/Union has with WKY CoalPlay. 

Though  there  is  geographic  overlap  between  the  Henderson/Union  and  River  View  properties,  the  resources  and 
reserves of each are associated with different coal seams or, if in the same seam, are separated by existing mine works or 
geologic features into distinct areas.  There is no overlap in the resource / reserve estimation. 

History 

The  Henderson/Union  property  contains  resources  in  three coal  seams,  the  WKY11,  the  WKY7,  and  the  WKY6. 
Island Creek operated mines in the area and controlled a portion of the property.  Under a joint venture, Texas Gas Service 
also controlled a large interest in the mineral rights.  Lastly, Peabody and Patriot operated mines in the area and controlled 
a portion of the reserves.  We consolidated control of the property through multiple transactions from 2005 through 2015.  
Island Creek operated the Ohio #11 mine.  Peabody and later Patriot operated the Camp complex and Highland #11 mine 
to the southeast and east.  The WKY11 seam was mined at these locations.  No mining has occurred on the property in the 

64 

 
 
 
 
 
 
WKY7 or WKY6 seams.  In general, all drilling has shown highly consistent coal seams of mineable thickness and quality 
for the high-sulfur thermal utility market.

History  

In November 1997, pursuant to (a) Assignment of Underground Coal Leases, (b) Partial Assignment of Underground 
Coal Leases and (c) Special Corporate Warranty Deed, Old Ben conveyed to MAPCO Land & Development Corporation 
various coal leases and fee coal interests within a large property boundary located in Gibson County, Indiana.  MAPCO 
Land & Development Corporation changed its name to MAPCO Coal Land & Development Corporation, and MAPCO 
Coal Land & Development Corporation merged into Alliance Properties effective August 4, 1999.   

After the original Old Ben acquisition, Alliance Properties and Gibson continued to acquire additional coal leases and 
fee coal interests in the area.  In addition, beginning in or around 2006, the leases originally acquired from Old Ben began 
to expire by their terms, and Alliance Properties/Gibson began a program of either amending the expiring leases or entering 
into new, direct leases with the coal owners.  Alliance Properties merged into Gibson on February 19, 2018.

Our mineral interests are primarily located in three basins, which are also our areas of focus for future development.  
These include the Permian (Delaware and Midland), Anadarko (SCOOP/STACK) and Williston (Bakken) Basins.  At 
December 31, 2023, we had 49,794 developed and undeveloped net acres held at a weighted average royalty of 17.0%. 
Our net acres standardized to 1/8th royalty equates to 67,745 net royalty acres, including 3,969 net royalty acres owned 
through our equity interest in AllDale III.   

The following table presents our estimated net proved oil & gas reserves, including our share of reserves attributable 
to  our  equity  interest  in  AllDale  III,  as  of  December  31,  2023  based  on  the  reserve  report  prepared  by  our  internal 
engineering team and reserve information provided by AllDale III. The reserve report and reserve information have been 
prepared in accordance with the rules and regulations of the SEC. All of our proved reserves are located in the continental 
United States.

2023. 

(2)  Natural gas reserve volumes are converted to BOE based on a 6:1 ratio: 6 Mcf of natural gas converts to one 

BOE. 

Estimates of reserves as of December 31, 2023 were prepared using product prices equal to the unweighted arithmetic 
average of the first-day-of-the-month market price for each month in the period from January through December 2023.  
The average realized product prices weighted by production over the remaining lives of the properties are $77.61/Bbl for 
oil, $1.55/Mcf of natural gas and $22.63 per barrel of NGL.  These prices are adjusted for energy content, associated 
average differential and transportation deducts by producing area to arrive at the net realized prices by product.  For 2023, 
NGL prices averaged approximately 33% of the posted oil prices during the course of the year with an additional $3.18/Bbl 
deducted for transportation costs.

As a mineral interest owner we have no transparency into or control over the Operators' investments and operational 
progress to convert PUDs to  proved developed producing reserves. We do not incur any capital expenditures or lease 
operating expenses in connection with the development of our PUDs, which costs are borne entirely by the Operators. As 
a result, during the year ended December 31, 2023, we did not have any expenditures to convert PUDs to proved developed 
producing reserves.  PUDs that have not been developed within two years of permitting are reviewed and removed from 
proved reserves as necessary. As of December 31, 2023, approximately 14.16% of our total proved reserves were classified 
as PUDs.  

Evaluation and Review of Reserves 

Numerous uncertainties are inherent in estimating reserve volumes and values, and the estimates are subject to change 
as additional information becomes available. The reserves actually recovered and the timing of production of the reserves 
may vary significantly from the original estimates.  

Under SEC rules, proved reserves are those quantities of oil & gas, which, by analysis of geoscience and engineering 
data, can be estimated with reasonable certainty to be economically producible–from a given date forward, from known 
reservoirs and under existing economic conditions, operating methods and government regulations–prior to the time at 
which  contracts  providing  the  right  to  operate  expire,  unless  evidence  indicates  that  renewal  is  reasonably  certain, 
regardless of whether deterministic or probabilistic methods are used for the estimation. If deterministic methods are used, 
the SEC has defined reasonable certainty for proved reserves as a "high degree of confidence that the quantities will be 
recovered."  All  of  our  proved  reserves  as  of  December  31,  2023  were  estimated  using  a  deterministic  method.  The 
estimation  of  reserves  involves  two  distinct  determinations.  The  first  determination  results  in  the  estimation  of  the 
quantities of recoverable oil & gas and the second determination results in the estimation of the uncertainty associated 
with those estimated quantities in accordance with the definitions established under SEC rules. The process of estimating 
the quantities of recoverable oil & gas reserves relies on the use of certain generally accepted analytical procedures. These 
analytical procedures fall into three broad categories or methods: 

(1)  performance-based methods,  
(2)  volumetric-based methods and 
(3)  analogy.  

These methods may be used singularly or in combination by the reserve evaluator in the process of estimating the 
quantities  of  reserves.  The  proved  reserves  for  our  properties  were  estimated  by  performance  methods,  analogy  or  a 
combination of both methods. Performance methods include, but may not be limited to, decline curve analysis, which 
utilized extrapolations of available historical production data. The analogy method was used where there were inadequate 
historical performance data to establish a definitive trend and where the use of production performance data as a basis for 
the reserve estimates was considered to be inappropriate.  

To  estimate  economically  recoverable  proved  reserves  and  related  future  net  cash  flows,  our  engineering  team 
considered many factors and assumptions, including the use of reservoir parameters derived from geological, geophysical 
and engineering data which cannot be measured directly, economic criteria based on current costs and the SEC pricing 
requirements  and  forecasts  of  future  production  rates.  To  establish  reasonable  certainty  with  respect  to  our  estimated 
proved reserves, the technologies and economic data used in the estimation of our proved reserves included production 
and well test data, downhole completion information, geologic data, electrical logs, and radioactivity logs.                         

Excluding our  share  of proved  reserves  held  by  AllDale  III,  our  2023  year-end  estimate  of  proved  reserves  were 
prepared by our internal engineering team.  Our engineering team works to ensure the integrity, accuracy, and timeliness 

75 

  
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
of the data used to calculate our estimated proved reserves. Our proved resource estimates were audited by CGA. Our 
engineering team met with CGA periodically during the period covered by the above referenced reserve report to discuss 
the assumptions and methods used in the reserve estimation process. Our engineering team provided historical information 
to CGA for our properties, such as oil & gas production, well test data, and realized commodity prices. Our engineering 
team  also  provided  ownership  interest  information  with  respect  to  our  properties.  Our  internal  petroleum  engineer, 
primarily responsible for overseeing the petroleum reserves preparation, has over 20 years of engineering and operations 
experience in the oil & gas sector and a Bachelor of Science in Petroleum Engineering. 

The preparation of our proved reserve estimates are completed in accordance with our internal control procedures. 

These procedures, which are intended to ensure reliability of reserve estimations, include the following: 

• 
• 
• 

• 
• 

• 

review and verification of historical data, which is based on actual production as reported by the Operators; 
verification of property ownership by our land department; 
review  of  all  our  reported  proved  reserves  semi-annually  including  the  review  of  all  significant  reserve 
changes and proved undeveloped reserves additions by our internal petroleum engineer; 
internally prepared reserve estimates compared to reserves audit by CGA; 
review of changes in reserves semi-annually by our internal petroleum engineer and by senior management; 
and 
no employee's compensation is tied to the amount of reserves booked. 

CGA, an independent third-party petroleum engineering firm, does not own an interest in any of our properties and is 
not employed on a contingent basis. When compared on a well-by-well basis, some of our estimates are greater and some 
are less than the CGA estimates. CGA is satisfied with our methods and procedures used to prepare the December 31, 
2023 reserve estimates and future revenue, and noted nothing of an unusual nature that would cause CGA to take exception 
with the estimates, in the aggregate, prepared by us. CGA's audit report with the respect to our proved reserve estimates 
as of December 31, 2023 is included as an exhibit to this Annual Report on Form 10-K. 

CGA was founded in 1961 and performs consulting petroleum engineering services under Texas Board of Professional 
Engineers Registration No. F-693. Within CGA, the technical person primarily responsible for auditing the estimates meets 
or exceed the education, training, and experience requirements set forth in the Standards Pertaining to the Estimating and 
Auditing of Oil and Gas Reserves Information promulgated by the Society of Petroleum Engineers and is proficient in 
judiciously applying industry-standard practices to engineering and geoscience evaluations as well as applying SEC and 
other industry reserves definitions and guidelines. 

Acreage Concentration 

Our  mineral  interests,  which  include  both  proved  reserves  discussed  above  and  unproved  reserves,  are  primarily 
located in three basins, which are also our areas of focus for future operator development.  These include the Permian 
(Delaware and Midland), Anadarko (SCOOP/STACK) and Williston (Bakken) Basins.  Below is a chart reflecting our 
gross,  net  mineral  and  net  royalty  acreage  associated  with  our  mineral  interests  in  each  of  our  primary  basins  as  of

Productive Wells 

As of December 31, 2023, 10,795 gross productive horizontal wells and 5,769 gross productive vertical wells were 
located on the acreage in which we have a mineral interest. Of our productive horizontal wells, 992 are considered natural 
gas wells, while the remaining 9,803 primarily produce oil.  Productive wells consist of producing wells and wells capable 
of production, including natural gas wells awaiting pipeline connections to commence deliveries and oil wells awaiting 
connection to production facilities.  We do not own any material working interests in any wells. Accordingly, we do not 
own any net wells. 

Drilling Results 

As a holder of mineral interests, we generally are not provided with information as to whether any wells drilled on 
the acreage associated with our mineral interests are classified as exploratory or as developmental wells. We are not aware 
of any dry holes drilled on the acreage associated with our mineral interests during the relevant period.

LEGAL PROCEEDINGS 

From time to time, we are party to litigation matters incidental to the conduct of our business.  It is the opinion of 
management that the ultimate resolution of our pending litigation matters will not have a material adverse effect on our 
financial condition, results of operation or liquidity.  However, we cannot assure you that disputes or litigation will not 
arise or that we will be able to resolve any such future disputes or litigation in a satisfactory manner.  The information 
under  "General  Litigation"  and  "Other"  in  "Item  8.    Financial  Statements  and  Supplementary  Data—Note  21  – 
Commitments and Contingencies" is incorporated herein by this reference. 

Litigation was initiated in November 2019 in the U.S. District Court for the Western District of Kentucky (Branson 
v. Webster County Coal, LLC et al.) against certain of our subsidiaries in which the plaintiffs allege violations of the Fair 
Labor Standards Act and state law due to alleged failure to compensate for time "donning" and "doffing" equipment and 
to account for certain bonuses in the calculation of overtime rates and pay. A similar lawsuit was initiated in March 2020 
in the U.S. District Court for the Eastern District of Kentucky (Brewer v. Alliance Coal, LLC, et al.). Subsequently, four 
additional lawsuits making similar allegations were initiated against certain of our subsidiaries: filed March 4, 2021 in the 
Circuit Court for Hopkins County, Kentucky (Johnson v. Hopkins County Coal, LLC, et al.); filed April 6, 2021 in the 
U.S. District Court for the Northern District of West Virginia (Rettig v. Mettiki Coal WV, LLC, et al.); filed April 9, 2021 
in the U.S. District Court for the Southern District of Illinois (Cates v. Hamilton County Coal, LLC, et al.); and filed April 
13, 2021 in the U.S. District Court for the Southern District of Indiana (Prater v. Gibson County Coal, LLC, et al.). The 
plaintiffs in these cases seek class and collective action certification, which we oppose, and the courts have not yet made

definitive final rulings on these issues. The plaintiffs seek to recover alleged compensatory, liquidated and/or exemplary 
damages for the alleged underpayment, and costs and fees that potentially may be recoverable under applicable law. We 
believe our ultimate exposure, if any, will not be material to our results of operations or financial position; however, if our 
current  belief  as  to  the  merit  of  the  claims  in  these  lawsuits  is  not  upheld,  it  is  reasonably  possible  that  the  ultimate 
resolution of these matters could result in a potential loss that may be material to our results of operations.

ITEM 5. 

MARKET FOR REGISTRANT'S COMMON EQUITY, RELATED UNITHOLDER 
MATTERS AND ISSUER PURCHASES OF EQUITY SECURITIES 

The common units representing limited partners' interests are listed on the NASDAQ Global Select Market under the 
symbol "ARLP." The common units began trading on August 20, 1999.  There were approximately 53,108 record holders 
of common units at December 31, 2023. 

Available cash with respect to each quarter may, at the discretion of our general partner, be distributed to the limited 
partners as of a record date selected by the general partner. "Available cash," as defined in our partnership agreement, 
generally means, with respect to any quarter, all cash on hand at the end of each quarter, plus working capital borrowings 
after the end of the quarter, less cash reserves in the amount necessary or appropriate in the reasonable discretion of our 
general partner to (a) provide for the proper conduct of our business, (b) comply with applicable law or any debt instrument 
or other agreement of ours or any of our affiliates, and (c) provide funds for distributions to unitholders for any one or 
more of the next four quarters.   

Equity Compensation Plans 

The information relating to our equity compensation plans required by Item 5 is incorporated by reference to such 
information  as  set  forth  in  "Item  12.  Security  Ownership of  Certain  Beneficial  Owners  and  Management  and  Related 
Unitholder Matters" contained herein. 

Unit Repurchase Program 

On May 31, 2018, ARLP announced that the Board of Directors approved the establishment of a unit repurchase 
program authorizing ARLP to repurchase up to $100 million of its outstanding limited partner common units. In January 
2023, the Board of Directors authorized a $93.5 million increase to the unit purchase program, which had $6.5 million of 
available capacity at the time. The unit repurchase program is intended to enhance ARLP's ability to achieve its goal of 
creating  long-term  value  for  its  unitholders  and  provides  another  means,  along  with  quarterly  cash  distributions,  of 
returning cash to unitholders. The program has no time limit and ARLP may repurchase units from time to time in the 
open market or other privately negotiated transactions. The unit repurchase program authorization does not obligate ARLP 
to repurchase any dollar amount or number of units, and repurchases may be commenced or suspended from time to time 
without prior notice.    

During the three months ended December 31, 2023, we did not repurchase and retire any units. Since the inception of 
the unit repurchase program, we have repurchased and retired 6,390,446 units at an average unit price of $17.67 for an

ITEM 7. 

MANAGEMENT'S  DISCUSSION  AND  ANALYSIS  OF  FINANCIAL  CONDITION  AND 
RESULTS OF OPERATIONS 

The following discussion of our financial condition and results of operations should be read in conjunction with the 
historical financial statements and notes thereto included in "Item 8. Financial Statements and Supplementary Data" where 
you can find more detailed information in "Note 1 – Organization and Presentation" and "Note 2 – Summary of Significant 
Accounting Policies" regarding the basis of presentation supporting the following financial information. 

Executive Overview 

Organization  

We are a diversified natural resource company that generates operating and royalty income from the production and 
marketing of coal to major domestic utilities, industrial users and international customers, as well as royalty income from 
oil & gas mineral interests located in strategic producing regions across the United States. In addition, we continue to 
position ourselves as a reliable energy provider for the future as we pursue opportunities that support the advancement of 
energy  and  related  infrastructure.  We  intend  to  pursue  strategic  investments  that  leverage  our  core  competencies  and 
relationships with electric utilities, industrial customers, and federal and state governments.  

We are currently the largest coal producer in the eastern United States with seven operating underground mining 
complexes near many of the major eastern utility generating plants and on major coal hauling railroads in Illinois, Indiana, 
Kentucky, Maryland, Pennsylvania, and West Virginia, as well as a coal-loading terminal in Indiana. Two of our mines 
also have loading facilities located on the Ohio River.  

In addition to our mining operations, Alliance Resource Properties owns or leases substantially all of our coal mineral 
resources and the majority of our coal mineral reserves in the Illinois and Appalachia Basins that are (a) leased to our 
internal mining complexes or (b) near our coal mining operations but not yet leased.  

We currently own minerals interests in approximately 67,700 net royalty acres in premier oil & gas producing regions 
of  the  United  States,  primarily  in  the  Permian  (Delaware  and  Midland),  Anadarko  (SCOOP/STACK)  and  Williston 
(Bakken) basins providing us with diversified exposure to industry-leading operators consistent with our general strategy 
to grow our oil & gas mineral interest business.  

We have invested in energy and infrastructure opportunities including our investments in Francis, Infinitum, NGP 
ET  IV,  and  Ascend  which  are  in  the  businesses  of,  respectively,  electric  vehicle  charging  stations,  electric  motor 
manufacturing, private equity investments in renewable energy, the electrification of our economy or the efficient use of 
energy, and the manufacturing and recycling of sustainable, engineered battery materials for electric vehicles.   

Please see "Item 1. Business and Item 2. Properties" in our Annual Report on Form 10-K for the year ended December 

31, 2023 for a more detailed discussion of our various businesses.   

As  of  December  31,  2023,  we  had  four  reportable  segments:  Illinois  Basin  Coal  Operations,  Appalachia  Coal 
Operations, Oil & Gas Royalties and Coal Royalties. We also have an "all other" category referred to as Other, Corporate 
and Elimination. Our two coal operations reportable segments correspond to major coal producing regions in the eastern 
United States with similar economic characteristics including coal quality, geology, coal marketing opportunities, mining 
and transportation methods and regulatory issues. Our Oil & Gas Royalties reportable segment includes our oil & gas 
mineral interests. Our Coal Royalties reportable segment includes coal mineral reserves and resources owned or leased by 
Alliance Resource Properties.   

•  The Illinois Basin Coal Operations reportable segment includes (a) the Gibson mining complex, (b) the Warrior 
mining complex, (c) the River View mining complex and (d) the Hamilton mining complex. The segment also 
includes our Mt. Vernon coal-loading terminal in Indiana which operates on the Ohio River, MAC and other 
support services, and our idled or closed mining complexes.  

80 

 
 
 
 
 
 
 
 
 
 
 
 
 
•  The Appalachia Coal Operations reportable segment includes (a) the Mettiki mining complex, (b) the Tunnel 

Ridge mining complex and (c) the MC Mining mining complex.  

•  The Oil & Gas Royalties reportable segment includes oil & gas mineral interests held by Alliance Minerals as 

well as our equity interests in AllDale III. 

•  The Coal Royalties reportable segment includes substantially all of our coal mineral resources and the majority 
of our coal mineral reserves owned or leased by Alliance Resource Properties. Approximately 60% of the coal 
sold by our coal operations' mines was leased from our Coal Royalties entities.  

•  Other,  Corporate  and  Elimination  includes  marketing  and  administrative  activities,  the  Matrix  Group,  our 
investments  in  Francis,  Infinitum,  NGP  ET  IV  and  Ascend,  Wildcat  Insurance,  which  assists  the  ARLP 
Partnership with its insurance requirements, AROP Funding and Alliance Resource Finance Corporation (both 
discussed in "Item 8. Financial Statements and Supplementary Data  – Note 6 – Long-Term Debt") and other 
miscellaneous activities. The eliminations included in Other, Corporate and Elimination primarily represent the 
intercompany coal royalty transactions described above between our Coal Royalties reportable segment and our 
coal operations' mines. 

Oil & Gas Acquisitions 

During 2023, through the JC Resources and Skyland Acquisitions and other ground game acquisitions, we acquired 
approximately  6,443  oil  &  gas  net  royalty  acres  in  the  Delaware,  Anadarko  and  Williston  basins.  These  acquisitions 
enhanced our ownership position in these basins and furthered our business strategy to grow our Oil & Gas Royalties 
segment  through  accretive  acquisitions.  See  "Item  8.  Financial  Statements  and  Supplementary  Data  –  Note  3  – 
Acquisitions" for more information. 

Growth Investments and Opportunities 

During  2023,  we  invested  $49.6  million  in  Infinitum  and  Ascend.  This  brings  our  total  investment  in  Francis, 
Infinitum, NGP ET IV and Ascend to $119.1 million with a remaining commitment of $18.4 million to NGP ET IV. See 
"Item 8. Financial Statements and Supplementary Data – Note 12 – Equity Investments" for additional information on 
Francis, Infinitum, NGP ET IV and Ascend. 

Risks and Uncertainties  

We  face  a  variety  of  risks  and  uncertainties  that  management  considers  in  the  operation  and  planning  of  our 
businesses, which could affect our financial position and results of operations. For additional information regarding our 
risks and uncertainties that affect our business and the industries in which we operate, see "Item 1A. Risk Factors". 

Business Strategy 

Our  primary  business  strategy  is  to  create  sustainable,  capital-efficient  growth  in  available  cash  to  maximize 

unitholder returns by: 

• 

• 

• 

•

• 

• 

strengthen and expand our technology company, Matrix Group, as we continue to develop and market industrial, 
mining and technology products and services worldwide; and 
continuing to identify and make strategic investments in the advancement of energy and related infrastructure 
opportunities to leverage our core competencies and build platforms for future lines of business with long-term 
growth and cash flow generation.   

How We Evaluate Our Performance 

Our  management uses  a  variety  of financial  and  operational  measurements  to  analyze  our  performance.  Primary 
measurements include the following: (1) coal sales price per ton; (2) BOE sold; (3) price per BOE; (4) coal royalty tons 
sold; (5) coal royalty revenue per ton; (6) Segment Adjusted EBITDA Expense per ton; (7) EBITDA; and (8) Segment 
Adjusted EBITDA. 

Coal Sales Price per Ton  

We define coal sales price per ton as total coal sales divided by tons sold. We review coal sales price per ton to 

evaluate marketing efforts and for market demand and trend analysis. 

Oil & gas BOE sold  

We  monitor  and  analyze  our BOE  sales  volumes  from  the  various  basins  that  comprise  our portfolio  of  mineral 
interests. We also regularly compare projected volumes to actual volumes reported and investigate unexpected variances. 

Price per BOE  

We define price per BOE as total oil & gas royalties divided by BOE produced. We review price per BOE to evaluate 

performance against budget and for trend analysis. 

Coal Royalty Tons sold  

We monitor and analyze our coal royalty sales volumes from our various mining subsidiaries for coal leased by 

Alliance Resource Properties for consistency with our coal operations segments and for trend analysis.  

Coal Royalty Revenue per Ton 

We define coal royalty revenue per ton as total coal royalties divided by royalty tons sold. We review coal royalty 

revenue per ton to evaluate consistency with our coal operations segments and for trend analysis. 

Segment Adjusted EBITDA Expense per Ton  

We define Segment Adjusted EBITDA Expense per ton (a non-GAAP financial measure) as the sum of operating 
expenses, coal purchases and other expense divided by total tons sold. We review Segment Adjusted EBITDA Expense 
per ton for cost trends. 

EBITDA 

We define EBITDA (a non-GAAP financial measure) as net income attributable to ARLP before net interest expense, 
income taxes and depreciation, depletion and amortization. EBITDA is used as a supplemental financial measure by our 
management and by external users of our financial statements such as investors, commercial banks, research analysts and 
others. We believe that the presentation of EBITDA provides useful information to investors regarding our performance 
and results of operations because EBITDA, when used in conjunction with related GAAP financial measures, (i) provides 
additional information about our core operating performance and ability to generate and distribute cash flow, (ii) provides 
investors with the financial analytical framework upon which we base financial, operational, compensation and planning 
decisions  and  (iii)  presents  a  measurement  that  investors,  rating  agencies  and  debt  holders  have  indicated  is  useful  in 
assessing us and our results of operations. 

82 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Segment Adjusted EBITDA 

We define Segment Adjusted EBITDA (a non-GAAP financial measure) as net income attributable to ARLP before 
net  interest  expense,  income  taxes,  depreciation,  depletion  and  amortization  and  general  and  administrative  expense. 
Management  therefore  is  able  to  focus  solely  on  the  evaluation  of  segment  operating  profitability  as  it  relates  to  our 
revenues and operating expenses, which are primarily controlled by our segments.   

Analysis of Historical Results of Operations – 2023 Compared with 2022 

Consolidated Information 

Total Revenues 

Total revenues increased 6.1% to a record $2.57 billion in 2023 compared to $2.42 billion in 2022 primarily due to 

higher coal sales revenues.   

Total operating expenses  

Total operating expenses increased to $1.89 billion in 2023 compared to $1.72 billion in 2022 due primarily to the 

sale of higher cost purchased coal and increased per ton costs on certain expense items discussed in more detail below.   

Net income attributable to ARLP 

Increased revenues and lower income tax expense more than offset higher total operating expenses in 2023, resulting 
in record net income attributable to ARLP of $630.1 million, or $4.81 per basic and diluted limited partner unit for 2023, 
compared to $586.2 million, or $4.39 per basic and diluted limited partner unit, for 2022. 

Coal sales  

Coal sales increased $108.0 million or 5.1% to $2.21 billion for 2023 from $2.10 billion for 2022. The increase reflects 
the benefit of higher average coal sales prices, which contributed $175.7 million in additional coal sales, partially offset 
by lower tons sold, which reduced coal sales by $67.7 million. Higher price realizations in domestic markets drove coal 
sales prices higher by 8.6% in 2023 to $64.17 per ton sold, compared to $59.07 per ton sold during 2022.  

Coal - Segment Adjusted EBITDA Expense  

Beginning in 2023, we redefined Coal - Segment Adjusted EBITDA Expense to reflect the activity of Alliance Coal, 
which is the holding company for our coal mining operations. We have retrospectively adjusted Coal - Segment Adjusted 
EBITDA Expense in prior periods to be on the same basis. 

Segment Adjusted EBITDA Expense for our coal operations increased 8.8% to $1.39 billion, as a result of higher per 
ton costs. On a per ton basis, Segment Adjusted EBITDA Expense for our coal operations increased 12.4% to $40.38 per 
ton sold in 2023 compared to $35.91 per ton in 2022, primarily due to certain cost increases, which are discussed below 
by category: 

•  Labor and benefit expenses per ton produced, excluding workers' compensation, increased 14.6% to $12.20 
per ton in 2023 from $10.65 per ton in 2022. The increase of $1.55 per ton was primarily due to higher 
incentive benefits and direct labor costs at several mines. 

•  Material and supplies expenses per ton produced increased 2.6% to $14.02 per ton in 2023 from $13.67 per 
ton in 2022. The increase of $0.35 per ton produced primarily reflects increases of $0.13 per ton for safety 
related materials and supplies, $0.11 per ton for various preparation plant expenses and $0.09 per ton for 
ventilation related expenses, partially offset by a decrease of $0.12 per ton for environmental and reclamation 
expenses other than longwall subsidence.  

•  Maintenance expenses per ton produced increased 27.6% to $4.62 per ton in 2023 from $3.62 per ton in 
2022. The increase of $1.00 per ton produced was primarily as a result of inflationary cost pressures. 

83 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
•  Production  taxes  and royalty expenses  per  ton  incurred  as a  percentage of  coal  sales  prices  and volumes 
increased  $0.64  per  produced  ton  sold  in  2023  compared  to  2022  primarily  as  a  result  of  higher  price 
realizations and higher federal black lung excise tax as a result of the tax rate increasing effective October 1, 
2022, partially offset by a favorable mix of tons sold mined in states without severance taxes.  

•  Outside coal purchases increased $36.0 million in 2023 as a result of increased sales from purchased coal to 
meet contractual commitments at our Mettiki longwall operation which experienced challenging geological 
conditions that delayed development of a new district. Purchased coal generally costs more on a per ton basis 
than our produced coal. 

For a definition of Segment Adjusted EBITDA Expense and related reconciliation to its comparable GAAP financial 

measure, please see below under "—Reconciliation of Non-GAAP Financial Measures." 

Oil & gas royalties  

Oil & gas royalty revenues decreased to $137.8 million in 2023 compared to $151.1 million for 2022. The decrease 
of $13.3 million was primarily due to lower average sales price per BOE, which decreased by 29.4%, partially offset by 
higher BOE volumes. 

Other revenues  

Other revenues principally comprised Matrix Design sales, Mt. Vernon transloading revenues, oil & gas lease bonus 
revenues, and other miscellaneous sales and revenue activities. Other revenues increased to $76.5 million in 2023 from 
$52.8 million in 2022. The increase of $23.7 million was primarily due to increased sales of mining technology products 
by our Matrix Design subsidiary. 

Income tax expense 

Income tax expense decreased to $8.3 million for 2023 compared to $54.0 million for 2022 primarily as a result of 
our  recognition  of  a  one-time  non-cash  income  tax  charge  of  $37.3  million  during  2022  in  connection  with  the  Tax 
Election. 

Transportation revenues and expenses  

Transportation revenues and expenses were $142.3 million and $113.9 million for 2023 and 2022, respectively. The 
increase  of  $28.4  million  was  primarily  attributable  to  increased  average  third-party  transportation  rates  in  2023  and 
increased coal shipments for which we arrange third-party transportation.  Transportation revenues are recognized when 
title to the coal passes to the customer and recognized in an amount equal to the corresponding transportation expenses. 

Segment Adjusted EBITDA  

Our 2023 Segment Adjusted EBITDA decreased $20.4 million, or 2.0%, to $1.01 billion from 2022 Segment Adjusted 
EBITDA of $1.03 billion primarily as a result of higher operating expenses and outside coal purchases, partially offset by 
increased revenues.

(5)  Represents tons sold by our coal operations segments associated with coal reserves leased from our Coal Royalties 

Segment. 

Illinois Basin Coal Operations – Segment Adjusted EBITDA increased 22.2% to $514.1 million in 2023 from $420.7 
million in 2022.  The increase of $93.4 million was primarily attributable to higher coal sales, which increased 11.9% to 
$1.36 billion in 2023 from $1.22 billion in 2022, partially offset by increased operating expenses. The increase in coal 
sales reflects higher coal sales price per ton, which increased by 9.1% compared to 2022 reflecting increased domestic 
prices, and increased tons sold, which rose 2.5% in 2023 as a result of increased sales volumes at the Warrior, Hamilton 
and Gibson South mines. Segment Adjusted EBITDA Expense increased 6.8% to $861.3 million in 2023 from $806.1 
million in 2022 primarily as a result of increased sales volumes and higher operating expenses per ton.  Segment Adjusted 
EBITDA Expense per ton increased 4.2% or $1.41 per ton sold to $34.84 from $33.43 per ton sold in 2022 primarily as a 
result of inflationary pressures on numerous expense items, including labor-related expenses and maintenance costs, and 
increased sales-related expenses due to higher price realizations, partially offset by lower expenses at our Hamilton mine, 
that experienced an unexpected outage during 2022. 

Appalachia Coal Operations – Segment Adjusted EBITDA decreased 22.4% to $330.7 million for 2023 from $426.2 
million in 2022.  The decrease of $95.5 million was primarily attributable to increased operating expenses and lower coal 
sales volumes.  Coal sales volumes decreased 15.3% compared to 2022 as a result of lower production across the region 
due to lock outages, customer plant maintenance, reduced operating units at MC Mining, challenging geologic conditions 
that delayed development of a new district at our Mettiki longwall operation and increased longwall move days at our 
Tunnel Ridge mine.  Coal sales prices increased by 13.2% compared to 2022 primarily due to increased domestic price 
realizations in the region.  Segment Adjusted EBITDA Expense increased 11.3% to $516.5 million in 2023 from $464.0 
million in 2022 due to higher per ton operating expenses, partially offset by lower volumes.  Segment Adjusted EBITDA 
Expense  per  ton  increased  31.5%  to  $53.15  compared  to  $40.42  per  ton  sold  in  2022,  as  a  result  of  lower  volumes 
previously  discussed,  purchased  coal  and  inflationary  pressures  on  certain  expense  items,  most  notably  labor-related 
expenses and materials and maintenance costs, and increased sales-related expenses due to higher price realizations. 

Oil & Gas Royalties – Segment Adjusted EBITDA decreased to $121.5 million for 2023 from $143.2 million in 2022.  
The decrease of $21.7 million was primarily due to lower average sales price per BOE, which decreased 29.4% to $44.37 
per BOE, partially offset by increased volumes in 2023, which increased by 29.1%. Higher BOE volumes during 2023 
resulted from increased drilling and completion activities on our properties and additional volumes from oil & gas mineral 
interest acquisitions. 

Coal Royalties – Segment Adjusted EBITDA increased 6.1% to $41.2 million for 2023 from $38.8 million in 2022.  
The $2.4 million increase was a result of higher average royalty rates per ton, partially offset by reduced royalty tons sold.

Total revenues increased 53.2% to a record $2.42 billion in 2022 compared to $1.58 billion in 2021 primarily due to 

substantial increases in prices and volumes from coal operations and royalties and oil & gas royalties.   

Total operating expenses  

Total  operating  expenses  increased  to  $1.75  billion  in  2022  compared  to  $1.36  billion  in  2021  due  primarily  to 

increased coal sales volumes and ongoing inflationary cost pressures.   

Net income attributable to ARLP 

Higher revenues, partially offset by increased total operating expenses and income tax expense, led to significantly 
higher net income attributable to ARLP, which rose 220.7% to a record $586.2 million for 2022, or $4.39 per basic and 
diluted limited partner unit, compared to $182.8 million, or $1.36 per basic and diluted limited partner unit, for 2021.

Coal sales  

Coal sales increased $715.3 million or 51.6% to $2.10 billion for 2022 from $1.39 billion for 2021.  The increase was 
attributable to a price variance of $572.6 million due to higher average coal sales prices and a volume variance of $142.7 
million resulting from increased tons sold.  Coal sales price realizations increased by 37.4% in 2022 to $59.07 per ton sold, 
compared to $42.98 per ton sold during 2021, due to favorable market conditions. Improved coal demand in both the 
domestic and export markets during 2022 drove coal sales volumes higher by 10.3% to 35.6 million tons sold compared 
to 32.3 million tons sold in 2021. 

Coal - Segment Adjusted EBITDA Expense  

Segment Adjusted EBITDA Expense for our coal operations increased 33.2% to $1.28 billion, as a result of higher 
coal sales volumes and inflationary cost pressures.  On a per ton basis, Segment Adjusted EBITDA Expense for our coal 
operations increased 20.8% to $35.91 per ton sold in 2022 compared to $29.73 per ton in 2021, primarily due to certain 
cost increases, which are discussed below by category: 

•  Labor and benefit expenses per ton produced, excluding workers' compensation, increased 14.6% to $10.65 
per ton in 2022 from $9.29 per ton in 2021.  The increase of $1.36 per ton was primarily due to higher labor 
costs at several mines. 

•  Material and supplies expenses per ton produced increased 32.8% to $13.67 per ton in 2022 from $10.29 per 
ton in 2021.  The increase of $3.38 per ton produced primarily reflects inflationary cost pressures including 
increases of $1.11 per ton for roof support, $0.47 per ton for ventilation related expenses, $0.43 per ton for 
power  and  fuel,  $0.39  per  ton  for  contract  labor  used  in  the  mining  process,  $0.37  per  ton  for  various 
preparation plant expenses and $0.26 per ton for environmental and reclamation expenses other than longwall 
subsidence.  

•  Maintenance expenses per ton produced increased 30.7% to $3.62 per ton in 2022 from $2.77 per ton in 
2021.  The increase of $0.85 per ton produced was primarily as a result of inflationary cost pressures. 

•  Production  taxes  and royalty expenses  per  ton  incurred  as a  percentage of  coal  sales  prices  and volumes 
increased  $0.68  per  produced  ton  sold  in  2022  compared  to  2021  primarily  as  a  result  of  higher  price 
realizations, partially offset by a temporary decrease in the federal black lung excise tax, from January 1, 
2022 to September 30, 2022, a favorable mix of tons sold mined in states with severance taxes and decreased 
excise taxes per ton resulting from a greater mix of export shipments.  

Oil & gas royalties  

Oil & gas royalty revenues increased to $151.1 million in 2022 compared to $84.2 million for 2021.  The increase of 

$66.9 million was primarily due to significantly higher sales price realizations per BOE and volumes in 2022. 

Other revenues  

Other revenues principally comprised Matrix Design sales, Mt. Vernon transloading revenues and other miscellaneous 
sales and revenue activities.  Other revenues increased to $52.8 million in 2022 from $38.5 million in 2021.  The increase 
of $14.3 million was primarily due to increased sales of mining technology products by our Matrix Design subsidiary. 

Income tax expense 

Income tax expense increased to $54.0 million for 2022 compared to $0.4 million for 2021 as a result of Alliance 
Minerals' election during 2022 to be treated as a taxable entity for federal and state income tax purposes.  We recognized 
a one-time non-cash income tax charge of $37.3 million and income tax expense of $17.5 million during 2022 related to 
Alliance Minerals.  Please read "Item 8. Financial Statements and Supplementary Data—Note 7 – Income Taxes."

Transportation revenues and expenses 

Transportation revenues and expenses were $113.9 million and $69.6 million for 2022 and 2021, respectively.  The 
increase  of  $44.3  million  was  primarily  attributable  to  increased  average  third-party  transportation  rates  in  2022  and 
increased coal shipments for which we arrange third-party transportation.  Transportation revenues are recognized when 
title to the coal passes to the customer and recognized in an amount equal to the corresponding transportation expenses. 

Segment Adjusted EBITDA 

Our  2022  Segment  Adjusted  EBITDA  increased  $475.2  million,  or  85.2%,  to  $1.03  billion  from  2021  Segment 
Adjusted  EBITDA  of  $557.4  million  primarily  as  a  result  of  increased  revenues,  partially  offset  by  higher  operating 
expenses.

(5)  Represents tons sold by our coal operations segments associated with coal reserves leased from our Coal Royalties 

Segment. 

Illinois Basin Coal Operations – Segment Adjusted EBITDA increased 58.6% to $420.7 million in 2022 from $265.3 
million in 2021.  The increase of $155.4 million was primarily attributable to higher coal sales, which increased 39.6% to 
$1.22 billion in 2022 from $873.9 million in 2021, partially offset by increased operating expenses. The increase in coal 
sales reflects higher coal sales price per ton, which increased by 28.9% compared to 2021 due to increased domestic prices 
and  significantly  higher  export  prices  and  increased  tons  sold,  which  rose  8.3%  in 2022  as  a  result  of  increased  sales 
volumes primarily at our Gibson South mine. Segment Adjusted EBITDA Expense increased 31.4% to $806.1 million in 
2022 from $613.3 million in 2021 primarily as a result of increased sales volumes and higher expenses per ton.  Segment 
Adjusted EBITDA Expense per ton increased 21.3% or $5.88 per ton sold to $33.43 from $27.55 per ton sold in 2021 
primarily as a result of inflationary pressures on numerous expense items, including labor-related expenses and supply and 
maintenance costs, increased sales-related expenses due to higher price realizations, reduced recoveries across the region 
and lost production due to an unexpected outage caused by a thermal event which lasted approximately four weeks in 
addition to increased longwall move days at our Hamilton mine during 2022.  There were no injuries and no damages to 
equipment as a result of the thermal event at Hamilton, and mining operations returned to normal production levels in 
December 2022. 

Appalachia Coal Operations – Segment Adjusted EBITDA increased 147.0% to $426.4 million for 2022 from $172.6 
million in 2021.  The increase of $253.8 million was primarily attributable to higher coal sales, which increased 72.0% to 
$882.3 million in 2022 from $513.0 million in 2021, due to increased prices and volumes.  Coal sales prices increased by 
49.9% compared to 2021 primarily due to substantially higher export price realizations and increased domestic pricing in 
the region.  Coal sales volumes increased 14.7% compared to 2021 as a result of higher sales volumes from our Tunnel 
Ridge and MC Mining operations.  Segment Adjusted EBITDA Expense increased 34.8% to $464.0 million in 2022 from 
$344.3 million in 2021 due to increased sales volumes and per ton expenses.  Segment Adjusted EBITDA Expense per 
ton increased 17.4% to $40.42 compared to $34.42 per ton sold in 2021, as a result of inflationary pressures on numerous 
expense items, including labor-related expenses and supply and maintenance costs, increased sales-related expenses due 
to higher price realizations, reduced recoveries at our Mettiki and MC Mining operations and increased longwall move 
days at our Tunnel Ridge and Mettiki mines during 2022. 

Oil & Gas Royalties – Segment Adjusted EBITDA increased to $143.2 million for 2022 from $76.9 million in 2021.  
The increase of $66.3 million was primarily due to higher sales price realizations, which increased 40.1% to $62.83 per 
BOE, and increased volumes in 2022.  Volumes increased by 28.1% to 2.4 million BOE sold in 2022 compared to 1.9 
million BOE sold in 2021 as a result of increased drilling and completion activities and additional volumes from oil & gas 
mineral interest acquisitions completed during 2022.  

Coal Royalties – Segment Adjusted EBITDA increased 16.9% to $38.8 million for 2022 from $33.2 million in 2021.  

The increase of $5.6 million was a result of increased royalty tons sold and higher average royalty rates per ton. 

Reconciliation of Non-GAAP Financial Measures  

Segment Adjusted EBITDA (a non-GAAP financial measure) is defined as net income attributable to ARLP before 
net  interest  expense,  income  taxes,  depreciation,  depletion  and  amortization  and  general  and  administrative  expenses.  
Segment  Adjusted  EBITDA  is  a  key  component  of  consolidated  EBITDA,  which  is  used  as  a  supplemental  financial 
measure by management and by external users of our financial statements such as investors, commercial banks, research 
analysts and others.  We believe that the presentation of EBITDA provides useful information to investors regarding our 
performance and results of operations because EBITDA, when used in conjunction with related GAAP financial measures, 
(i) provides additional information about our core operating performance and ability to generate and distribute cash flow, 
(ii) provides investors with the financial analytical framework upon which we base financial, operational, compensation 
and planning decisions and (iii) presents a measurement that investors, rating agencies and debt holders have indicated is 
useful in assessing us and our results of operations. 

Segment Adjusted EBITDA is also used as a supplemental financial measure by our management for reasons similar 
to those stated in the previous explanation of EBITDA.  In addition, the exclusion of corporate general and administrative 
expenses  from consolidated Segment Adjusted EBITDA allows management to focus solely on the evaluation of segment 
operating profitability as it relates to our revenues and operating expenses, which are primarily controlled by our segments.

Segment Adjusted EBITDA Expense (a non-GAAP financial measure) includes operating expenses, coal purchases 
and other expense (income).  Transportation expenses are excluded as these expenses are passed through to our customers 
and, consequently, we do not realize any gain or loss on transportation revenues.  Segment Adjusted EBITDA Expense is 
used  as  a  supplemental  financial  measure  by  our  management  to  assess  the  operating  performance  of  our  segments.  
Segment Adjusted EBITDA Expense is a key component of Segment Adjusted EBITDA in addition to coal sales, royalty 
revenues and other revenues.  The exclusion of corporate general and administrative expenses from Segment Adjusted 
EBITDA Expense allows management to focus solely on the evaluation of segment operating performance as it primarily 
relates to our operating expenses.

Ongoing Acquisition Activities 

Consistent with our business strategy, from time to time we engage in discussions with potential sellers regarding our 
possible acquisitions of certain assets and/or companies of the sellers. For more information on acquisitions, please read 
"Item  8.  Financial  Statements  and  Supplementary  Data—Note  1  –  Organization  and  Presentation"  and  "—Note  3  – 
Acquisitions" of this Annual Report on Form 10-K. 

 Liquidity and Capital Resources 

Liquidity 

We have historically satisfied our working capital requirements and funded our capital expenditures, investments, 
contractual obligations and debt service obligations with cash generated from operations, cash provided by the issuance of 
debt  or  equity,  borrowings  under  credit  and  securitization  facilities  and  other  financing  transactions.  We  believe  that 
existing cash balances, future cash flows from operations and investments, borrowings under credit facilities and cash 
provided  from  the  issuance  of  debt  or  equity  will  be  sufficient  to  meet  our  working  capital  requirements,  capital 
expenditures and additional investments, debt payments, contractual obligations, commitments and distribution payments.  
Nevertheless, our ability to satisfy our working capital requirements and additional investments, to satisfy our contractual 
obligations, to fund planned capital expenditures, to service our debt obligations or to pay distributions will depend upon 
our  future  operating  performance  and  access  to  and  cost  of  financing  sources,  which  will  be  affected  by  prevailing 
economic conditions generally, and in both the coal and oil & gas industries specifically, as well as other financial and 
business factors, some of which are beyond our control. Based on our recent operating cash flow results, current cash 
position, anticipated future cash flows and sources of financing that we expect to have available, we anticipate being in 
compliance with the covenants of the Credit Agreement and expect to have sufficient liquidity to fund our operations and 
growth strategies. However, to the extent operating cash flow or access to and cost of financing sources are materially 
different than expected, future covenant compliance or liquidity may be adversely affected. Please see "Item 1A. Risk 
Factors." 

Oil & Gas Acquisitions 

During 2023, through the JC Resources and Skyland Acquisitions and other ground game acquisitions we acquired 
approximately 6,443 oil & gas net royalty acres in the Anadarko, Williston and Delaware Basins for an aggregate purchase 
price of $110.9 million. We funded these acquisitions with cash on hand. For additional information about our acquisitions 
of oil & gas assets, please see "Business — Oil & Gas Acquisitions." 

Growth Investments and Opportunities 

During 2023, we invested $49.6 million in Infinitum and Ascend with cash on hand. These investments are aligned 
with our strategy of furthering the development of energy and related infrastructure and investing in attractive opportunities 
that leverage our core competencies and build platforms for future lines of business with long-term growth and cash flow 
generation. Also, as of December 31, 2023, we have funded $6.6 million of a $25 million commitment in NGP ET IV with 
cash on hand. For additional information about our energy and infrastructure investments, please see "Business — Growth 
Investments and Opportunities." 

Unit Repurchase Program 

In January 2023, the Board of Directors authorized a $93.5 million increase to the unit repurchase program. As a 
result, we were authorized to repurchase up to a total of $100.0 million of ARLP's limited partner common units. During 
the year ended December 31, 2023, we repurchased and retired 929,842 units at an average price of $20.90 for an aggregate 
purchase price of $19.4 million, leaving $80.6 million authorized. Please read "Item 5. Market for Registrant's Common 
Equity, Related Unitholder Matters and Issuer Purchases of Equity Securities" for more information on the unit repurchase 
program.  

Revolving Credit Facility 

On January 13, 2023, Alliance Coal entered into the Credit Agreement with various financial institutions. The Credit 
Agreement provides for a $425 million revolving credit facility, which includes a sublimit of $15.0 million for swingline 

92 

 
 
 
 
 
 
 
 
 
 
 
 
borrowings and permits the issuance of letters of credit of up to the full amount of $425 million, and for a term loan in an 
aggregate principal amount of $75 million. The Credit Agreement matures on March 9, 2027, at which time the aggregate 
outstanding principal amount of all Revolving Credit Facility advances and all Term Loan advances are required to be 
repaid in full. The Credit Agreement will instead mature on January 30, 2025, if on that date our Senior Notes are still 
outstanding and Alliance Coal does not have liquidity of at least $200 million. Interest is payable quarterly, with principal 
of the Term Loan due in quarterly installments equal to 6.25% of the original principal amount beginning with the quarter 
ending June 30, 2023 and the balance payable at maturity. The Credit Agreement is guaranteed by ARLP and certain of 
its subsidiaries, including the Intermediate Partnership and most of the direct and indirect subsidiaries of Alliance Coal. 
The Credit Agreement also is secured by substantially all of the assets of the Subsidiary Guarantors and Alliance Coal. 
For additional information on the Credit Agreement, please see "Item 8. Financial Statements and Supplementary Data—
Note 6 – Long-Term Debt". 

Securitization Facility 

In January 2024, we extended the term of our Securitization Facility to January 2025 and increased the borrowing 
availability under the facility to $90.0 million. For additional information on the Securitization Facility please read "Item 
8. Financial Statements and Supplementary Data—Note 6 – Long-Term Debt".  

Mine Development Project  

In 2022, we began development of the Henderson County mine which continued through 2023 and into 2024.  We 
have deployed capital of $69.3 million through 2023 and currently anticipate deploying capital of approximately $36.5 
million in 2024 to complete the project. We have funded our capital expenditures and expect to fund our remaining capital 
expenditures for the project with cash from operations or borrowings under our credit facilities.  We anticipate the new 
mine will enable us to access an additional 109.5 million clean recoverable tons of coal. 

Cash Flows 

Cash provided by operating activities was $830.6 million for 2023 compared to $802.3 million for 2022. The increase 
in cash provided by operating activities was primarily due to increases in net income adjusted for non-cash items  and 
favorable  working  capital  changes  primarily  related  to  trade  receivables.  These  increases  were  partially  offset  by 
unfavorable working capital changes primarily related to inventories, as well as miscellaneous other changes. 

Net cash used in investing activities was $559.7 million for 2023 compared to $403.3 million for 2022. The increase 
in cash used in investing activities was primarily attributable to increases in capital expenditures, acquisitions of oil & gas 
reserves including the JC Resources and Skyland Acquisitions, and changes in accounts payable and accrued liabilities. 
These increases were partially offset by payments for the Belvedere and Jase Acquisitions, and contributions to equity 
method investments in 2022. See "Item 8. Financial Statements and Supplementary Data—Note 3 – Acquisitions" for 
more information on the Belvedere, Jase, JC Resources and Skyland Acquisitions. 

Net cash used in financing activities was $507.1 million for 2023 compared to $225.4 million for 2022. The increase 
in cash used in financing activities was primarily attributable to increased cash distributions paid to unitholders, increased 
net payments on long-term debt, purchases of units under our unit repurchase program, debt issuance costs, and payments 
for purchase of units and tax withholdings related to settlements under deferred compensation plans. 

Cash Requirements  

We currently estimate our 2024  annual cash requirements, including capital expenditures, scheduled payments on 
long-term debt, lease obligations, asset retirement obligation costs and workers' compensation and pneumoconiosis, to be 
in a range of $728.0 million to $778.0 million. Management anticipates having sufficient cash flow to meet 2024 cash 
requirements with our December 31, 2023 cash and cash equivalents of $59.8 million and cash flows from operations, or 
borrowings under revolving credit and securitization facilities or other sources of financing that we expect to have available 
if necessary. We currently project average estimated annual maintenance capital expenditures over the next five years of 
approximately  $7.76  per  ton  produced.  For  additional  information  on  our  future  cash  requirements  other  than  capital 
expenditures, please see "Item 8. Financial Statements and Supplementary Data—Note 6 – Long-Term Debt," "—Note 8 
– Leases," "—Note 15 – Employee Benefit Plans," "—Note 18 – Asset Retirement Obligations," "—Note 19 – Accrued 
Workers'  Compensation  and Pneumoconiosis  Benefits"  and  "—Note  21  –  Commitments  and  Contingencies."  We  will 

93 

 
 
 
 
 
 
 
 
 
 
continue to have significant cash requirements over the long term, which may require us to incur debt or seek additional 
equity capital. The availability and cost of additional capital will depend upon prevailing market conditions, the market 
price of our common units and several other factors over which we have limited control, as well as our financial condition 
and results of operations. 

We use a combination of surety bonds and letters of credit to secure our financial obligations for reclamation, workers' 

compensation and other obligations as follows as of December 31, 2023:

Insurance 

Effective October 1, 2023, we renewed our property and casualty insurance program through September 30, 2024. 
Our property insurance was procured from our wholly owned captive insurance company, Wildcat Insurance. Wildcat 
Insurance charged certain of our subsidiaries for the premiums on this program and in return purchased reinsurance for the 
program in the standard market. The maximum limit in the commercial property program is $100.0 million per occurrence, 
excluding  a  $1.5  million  deductible  for  property  damage,  a  75  or  90  day  waiting  period  for  underground  business 
interruption depending on the mining complex and an additional $25.0 million overall aggregate deductible. We retained 
a 7.25% participating interest in our current commercial property insurance program. We can make no assurances that we 
will not experience significant insurance claims in the future that could have a material adverse effect on our business, 
financial condition, results of operations and ability to purchase property insurance in the future. Also, exposures exist for 
which no insurance may be available and for which we have not reserved. In addition, the insurance industry has been 
subject to efforts by environmental activists to restrict coverages available for fossil-fuel companies. 

Debt Obligations 

See "Item 8. Financial Statements and Supplementary Data—Note 6 – Long-Term Debt" for a discussion of our debt 

obligations. 

Critical Accounting Policies and Estimates 

Our discussion and analysis of our financial condition, results of operations, liquidity and capital resources is based 
on our consolidated financial statements, which have been prepared in accordance with accounting principles generally 
accepted  in  the  United  States.  The  preparation  of  our  consolidated  financial  statements  requires  management  to  make 
estimates and assumptions that affect the reported amounts and disclosures in the consolidated financial statements. We 
base our estimates on historical experience and on various other assumptions that we believe are reasonable under the 
circumstances. We discuss these estimates and judgments with the Audit Committee periodically. Actual results may differ 
from these estimates. We have provided a description of all significant accounting policies in the notes to our consolidated 
financial statements. The following critical accounting policies are materially impacted by judgments, assumptions and 
estimates used in the preparation of our consolidated financial statements: 

Business Combinations  

We account for business acquisitions using the purchase method of accounting. See "Item 8. Financial Statements and 
Supplementary  Data—Note  3  –  Acquisitions"  for  more  information on  the  Belvedere,  Jase  and  Skyland  Acquisitions.  
Assets acquired and liabilities assumed are recorded at their estimated fair values at the acquisition date. The excess of 
purchase price over fair value of net assets acquired, if any, is recorded as goodwill. Given the time it takes to obtain 
pertinent information to finalize the acquired business' balance sheet, it may be several quarters before we are able to 
finalize those initial fair value estimates. Accordingly, it is not uncommon for the initial estimates  to be subsequently 
revised. The results of operations of acquired businesses are included in the consolidated financial statements from the 
acquisition date.

For the Belvedere, Jase and Skyland Acquisitions, we determined a fair value for the acquired mineral interests using 
an income approach consisting of discounted cash flow models. The assumptions used in the discounted cash flow models 
included estimated production, projected cash flows, forward oil & gas prices and risk adjusted discount rates. 

Oil & Gas Reserve Values 

Estimated  oil  &  gas  reserves  and  estimated  market  prices  for  oil  &  gas  are  a  significant  part  of  our  depletion 
calculations, impairment analyses, and other estimates. Following are examples of how these estimates affect financial 
results: 

• 

• 

an  increase  (decrease)  in  estimated  proved  oil  &  gas  reserves  can  reduce  (increase)  our  units  of  production 
depreciation, depletion and amortization rates; and 
changes  in  oil  &  gas  reserves  and  estimated  market  prices  both  impact  projected  future cash  flows  from  our 
mineral interests. This in turn can impact our periodic impairment analysis. 

The process of estimating oil & gas reserves is very complex, requiring significant judgment in the evaluation of all 
available geological, geophysical, engineering and economic data. After being estimated internally, our proved reserves 
estimates are compared to proved reserves that are audited by independent experts in connection with our required year-
end reporting. The data may change substantially over time as a result of numerous factors, including the historical 12 
month average price, additional development cost and activity, evolving production history and a continual reassessment 
of  the  viability  of  production  under  changing  economic  conditions.  As  a  result,  material  revisions  to  existing  reserve 
estimates could occur from time to time. Such changes could trigger an impairment of our oil & gas mineral interests and 
have an impact on our depreciation, depletion and amortization expense prospectively.  

Estimates  of  future  commodity  prices  utilized  in  our  impairment  analyses  consider  market  information  including 
published forward oil & gas prices. The forecasted price information used in our impairment analyses is consistent with 
that generally used in evaluating third-party operator drilling decisions and our expected acquisition plans, if any. Prices 
for future periods will impact the production economics underlying oil & gas reserve estimates. In addition, changes in 
the price of oil & gas also impact certain costs associated with our expected underlying production and future capital costs. 
The prices of oil & gas are volatile and change from period to period, thus are expected to impact our estimates. Significant 
unfavorable changes in the estimated future commodity prices could result in an impairment of our oil & gas mineral 
interests.   

Workers' Compensation and Pneumoconiosis (Black Lung) Benefits 

We  provide  income  replacement  and  medical  treatment  for  work-related  traumatic  injury  claims  as  required  by 
applicable  state  laws.  We  generally  provide  for  these  claims  through  self-insurance  programs.  Workers'  compensation 
laws also compensate survivors of workers who suffer employment related deaths. Our liability for traumatic injury claims 
is the estimated present value of current workers' compensation benefits, based on our actuary estimates. Our actuarial 
calculations are based on a blend of actuarial projection methods and numerous assumptions including claim development 
patterns, mortality, medical costs and interest rates. See "Item 8. Financial Statements and Supplementary Data—Note 19 
– Accrued Workers' Compensation and Pneumoconiosis Benefits" for additional discussion. We had accrued liabilities for 
workers' compensation of $48.0 million and $49.5 million for these costs at December 31, 2023 and 2022, respectively.  
A  one-percentage-point  reduction  in  the  discount  rate  would  have  increased  operating  expense  by  approximately  $2.4 
million at December 31, 2023. We limit our exposure to traumatic injury claims by purchasing a high deductible insurance 
policy that starts paying benefits after deductibles for a particular claim year have been met. Our receivables for traumatic 
injury claims under this policy as of December 31, 2023 and 2022 were $4.1 million. 

Coal mining companies are subject to FMSHA and various state statutes for the payment of medical and disability 
benefits to eligible recipients related to coal worker's pneumoconiosis, or black lung. We provide for these claims through 
self-insurance programs. Our pneumoconiosis benefits liability is calculated using the service cost method based on the 
actuarial  present  value  of  the  estimated  pneumoconiosis  benefits  obligation.  Our  actuarial  calculations  are  based  on 
numerous assumptions including disability incidence, medical costs, mortality, death benefits, dependents and discount 
rates. We had accrued liabilities of $132.4 million and $104.3 million for the pneumoconiosis benefits at December 31, 
2023 and 2022, respectively. A one-percentage-point reduction in the discount rate would have increased the expense 
recognized for the year ended December 31, 2023 by approximately $1.4 million. Under the service cost method used to 

95 

 
 
 
 
 
 
 
 
estimate our pneumoconiosis benefits liability, actuarial gains or losses attributable to changes in actuarial assumptions, 
such as the discount rate, are amortized over the remaining service period of active miners. 

The discount rate for workers' compensation and pneumoconiosis is derived by applying the Financial Times Stock 
Exchange  Pension  Discount  Curve  to  the  projected  liability  payout.  Other  assumptions,  such  as  claim  development 
patterns, mortality, disability incidence and medical costs, are based on standard actuarial tables adjusted for our actual 
historical  experiences  whenever  possible.  We  review  all  actuarial  assumptions  periodically  for  reasonableness  and 
consistency  and  update  such  factors  when  underlying  assumptions,  such  as  discount  rates,  change  or  when  sustained 
changes in our historical experiences indicate a shift in our trend assumptions are warranted. 

Asset Retirement Obligations 

SMCRA and similar state statutes require that mined property be restored in accordance with specified standards and 
an approved reclamation plan. A liability is recorded for the estimated cost of future mine asset retirement and closing 
procedures on a present value basis when incurred or acquired and a corresponding amount is capitalized by increasing 
the carrying amount of the related long-lived asset. Those costs relate to permanently sealing portals at underground mines 
and  to  reclaiming  the  final  pits  and  support  surface  acreage  for  both  our  underground  mines  and  past  surface  mines.  
Examples of these types of costs, common to both types of mining, include, but are not limited to, removing or covering 
refuse  piles  and  settling  ponds,  water  treatment  obligations,  and  dismantling  preparation  plants,  other  facilities  and 
roadway infrastructure. Accrued liabilities of $150.4 million and $149.8 million for these costs are recorded at December 
31, 2023 and 2022, respectively. See "Item 8. Financial Statements and Supplementary Data—Note 18 – Asset Retirement 
Obligations" for additional information. The liability for asset retirement and closing procedures is sensitive to changes in 
cost estimates, estimated mine lives and timing of post-mine reclamation activities. As changes in estimates occur (such 
as mine plan revisions, changes in estimated costs or changes in timing of the performance of reclamation activities), the 
revisions to the obligation and asset are recognized at the appropriate credit-adjusted, risk-free interest rate. 

Accounting  for  asset  retirement  obligations  also  requires  depreciation  of  the  capitalized  asset  retirement  cost  and 
accretion of the asset retirement obligation over time. Depreciation is generally determined on a units-of-production basis 
and accretion is generally recognized over the life of the producing assets. 

On at least an annual basis, we review our entire asset retirement obligation liability and make necessary adjustments 
for permit changes approved by state authorities, changes in the timing of reclamation activities, and revisions to cost 
estimates and productivity assumptions, to reflect current experience. Adjustments to the liability associated with these 
assumptions resulted in a decrease of $1.5 million for the year ended December 31, 2023. Adjustments to the liability 
associated with these assumptions resulted in an increase of $17.4 million for the year ended December 31, 2022.    

While the precise amount of these future costs cannot be determined with certainty, we have estimated the costs and 
timing of future asset retirement obligations escalated for inflation, then discounted and recorded at the present value of 
those estimates. Discounting resulted in reducing the accrual for asset retirement obligations by $116.2 million and $110.4 
million  at  December  31,  2023  and  2022.  We  estimate  that  the  aggregate  undiscounted  cost  of  final  mine  closure  is 
approximately $266.6 million and $260.2 million at December 31, 2023 and 2022, respectively. If our assumptions differ 
from actual experiences, or if changes in the regulatory environment occur, our actual cash expenditures and costs that we 
incur could be materially different than currently estimated. 

Shelf Registration Statement 

In February 2022, we filed with the SEC a universal shelf registration statement which allows us to issue from time 
to time an indeterminate amount of debt or equity securities. As of February 23, 2024, we had not issued any debt or equity 
under the 2022 Registration Statement. 

Related–Party Transactions

of our related-party transactions. 

96 

 
 
 
 
 
 
 
 
 
 
 
Accruals of Other Liabilities 

We  had  accruals  for  other  liabilities,  including  current  obligations,  totaling  $398.4  million  and  $395.3  million  at 
December 31, 2023 and 2022, respectively. These accruals were chiefly comprised of workers' compensation benefits, 
pneumoconiosis benefits, and costs associated with asset retirement obligations. These obligations are self-insured except 
for certain excess insurance coverage for workers' compensation. The accruals of these items were based on estimates of 
future expenditures based on current legislation, related regulations and other developments. Thus, from time to time, our 
results of operations may be significantly affected by changes to these liabilities. Please see "Item 8. Financial Statements 
and Supplementary Data—Note 18 – Asset Retirement Obligations" and "—Note 19 – Accrued Workers' Compensation 
and Pneumoconiosis Benefits."

for a discussion of new accounting standards. 

ITEM 7A. 

QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK 

Commodity Price Risk 

We have significant long-term sales contracts as evidenced by approximately 93.4% of our sales tonnage being sold 
under long-term sales contracts in 2023.  Many of the long-term sales contracts are subject to price adjustment provisions, 
which periodically permit an increase or decrease in the contract price, typically to reflect changes in specified indices or 
changes  in  production  costs  resulting  from  regulatory  changes,  or  both.    For  additional  discussion  of  coal  supply 
agreements,  please  see  "Item  1.  Business—Coal  Marketing  and  Sales"  and  "Item  8.  Financial  Statements  and 
Supplementary Data—Note 22 – Concentration of Credit Risk and Major Customers."  Our initial 2024 guidance includes 
32.5 million priced and committed tons for delivery in 2024.   

Our results of operations are highly dependent upon the prices we receive for our coal, oil and natural gas.  Regarding 
coal, the short-term sales contracts favored by some of our coal customers leave us more exposed to risks of declining coal 
price periods.  Also, a significant decline in oil & gas prices would have a significant impact on our oil & gas royalty 
revenues.     

We have exposure to coal and oil & gas sales prices and price risk for supplies that are used directly or indirectly in 
the normal course of coal and oil & gas production such as steel, electricity and other supplies. We manage our risk for 
these items through strategic sourcing contracts for normal quantities required by our operations.  Historically, we have 
not utilized any commodity price-hedges or other derivatives related to either our sales price or supply cost risks but may 
do so in the future. 

Credit Risk 

In 2023, approximately 80.9% of our tons sold were purchased by U.S. electric utilities and 15.7% were sold into the 
international markets through brokered transactions.  Therefore, our credit risk is primarily with domestic electric power 
generators and reputable global brokerage firms.  Our policy is to independently evaluate each customer's creditworthiness 
prior to entering into transactions and to constantly monitor outstanding accounts receivable. When deemed appropriate 
by our credit management department, we will take steps to reduce our credit exposure to customers that do not meet our 
credit standards or whose credit has deteriorated. These steps may include obtaining letters of credit or cash collateral, 
requiring prepayments for shipments or establishing customer trust accounts held for our benefit in the event of a failure 
to pay. Such credit risks from customers may impact the borrowing capacity of our Securitization Facility.  See "Item 8. 
Financial Statements and Supplementary Data—Note 6 – Long-Term Debt" for more information on our Securitization 
Facility. 

Exchange Rate Risk 

The vast majority of our transactions are denominated in United States dollars, and as a result, we do not have material 
exposure to currency exchange-rate risks. However, because coal is sold internationally in United States dollars, general 
economic  conditions  in  foreign  markets  and  changes  in  foreign  currency  exchange  rates  may  provide  our  foreign 

97 

 
 
 
 
 
 
 
 
 
 
 
 
competitors with a competitive advantage. If our competitors' currencies decline against the United States dollar or against 
foreign purchasers'  local  currencies,  those  competitors  may  be  able  to  offer  lower  prices  for  coal  to  these  purchasers. 
Furthermore, if the currencies of overseas purchasers were to significantly decline in value in comparison to the United 
States dollar, those purchasers may seek decreased prices for the coal we sell to them. Consequently, currency fluctuations 
could adversely affect the competitiveness of our coal in international markets. 

Interest Rate Risk 

Borrowings under the Revolving Credit Facility, Term Loan and Securitization Facility are at variable rates and, as a 
result, we have interest rate exposure. Historically, our earnings have not been materially affected by changes in interest 
rates and we have not utilized interest rate derivative instruments related to our outstanding debt.  We had $60.9 million 
in  borrowings  under  Term  Loan  at  December  31,  2023.    We  did  not  have  any  outstanding  borrowings  on  either  the 
Revolving  Credit  Facility  or  the  Securitization  Facility  at  December 31,  2023.  A one  percentage  point  increase  in  the 
interest rates related to the Term Loan would result in an annualized increase in interest expense of $0.6 million, based on 
borrowing levels at December 31, 2023. With respect to our fixed-rate borrowings, we had $284.6 million in borrowings 
under our Senior Notes and $2.0 million in borrowings under our equipment financings at December 31, 2023.  A one 
percentage point increase in interest rates would result in a decrease of approximately $3.7 million in the estimated fair 
value of these borrowings. 

The table below provides information about our market sensitive financial instruments and constitutes a "forward-
looking statement." The fair values of long-term debt are estimated using discounted cash flow analyses, based on our 
incremental borrowing rates for similar types of borrowing arrangements as of December 31, 2023 and 2022.

Unitholders of Alliance Resource Partners, L.P. 

Opinion on the financial statements 
We have audited the accompanying consolidated balance sheets of Alliance Resource Partners, L.P. (a Delaware limited 
partnership) and subsidiaries (the “Partnership”) as of December 31, 2023 and 2022, the related consolidated statements 
of  income,  comprehensive  income,  cash  flows  and  partners’  capital  for  each  of  the  three  years  in  the  period  ended 
December  31, 2023,  and  the related  notes  and financial  statement  schedule  included  under  Item  15(a)(2)  (collectively 
referred to as the “financial statements”). In our opinion, the financial statements present fairly, in all material respects, 
the financial position of the Partnership as of December 31, 2023 and 2022, and the results of its operations and its cash 
flows  for  each  of  the  three  years  in  the  period  ended  December  31,  2023,  in  conformity  with  accounting  principles 
generally accepted in the United States of America. 

We  also  have  audited,  in  accordance  with  the  standards  of  the  Public  Company  Accounting  Oversight  Board  (United 
States) (“PCAOB”), the Partnership’s internal control over financial reporting as of December 31, 2023, based on criteria 
established in the 2013 Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations 
of the Treadway Commission (“COSO”), and our report dated February 23, 2024 expressed an unqualified opinion. 

Basis for opinion 
These  financial  statements  are  the  responsibility  of  the  Partnership’s  management.  Our  responsibility  is  to  express  an 
opinion on the Partnership’s financial statements based on our audits. We are a public accounting firm registered with the 
PCAOB and are required to be independent with respect to the Partnership in accordance with the U.S. federal securities 
laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.  

We  conducted  our  audits  in  accordance  with  the  standards  of  the  PCAOB.  Those  standards  require  that  we  plan  and 
perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, 
whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of 
the  financial  statements,  whether  due  to  error  or  fraud,  and  performing  procedures  that  respond  to  those  risks.  Such 
procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. 
Our audits also included evaluating the accounting principles used and significant estimates made by management, as well 
as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for 
our opinion.  

Critical audit matter 
The critical audit matter communicated below is a matter arising from the current period audit of the financial statements 
that  was  communicated  or  required  to  be  communicated  to  the  audit  committee  and  that:  (1)  relates  to  accounts  or 
disclosures that are material to the financial statements and (2) involved our especially challenging, subjective, or complex 
judgments. The communication of critical audit matters does not alter in any way our opinion on the financial statements, 
taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the 
critical audit matter or on the accounts or disclosures to which it relates. 

Valuation of workers’ compensation and pneumoconiosis benefit obligations 

As described further in Note 19  to the financial statements, the Partnership provides income replacement and medical 
treatment for work-related traumatic injury claims and compensation to survivors of workers who suffer employment-
related  deaths.    The  Partnership  is  also  liable  to  pay  benefits  for  black  lung  disease  (or  pneumoconiosis)  to  eligible 
employees and former employees and their dependents.  As of December 31, 2023, the Partnership’s aggregate workers’ 
compensation  and  pneumoconiosis  benefit  obligations  were  approximately  $180  million.  We  identified  valuation  of 
workers’ compensation and pneumoconiosis benefit obligations as a critical audit matter.   

The  principal  considerations  for  our  determination  that  the  valuation  of  workers’  compensation  and  pneumoconiosis 
benefit obligations is a critical audit matter are the high level of estimation uncertainty related to determining the frequency 
and severity of these types of claims, as well as the inherent subjectivity in management’s judgment in estimating eligible 
benefits  and  the  total  cost  to  settle  or  dispose  of  these  claims.  Workers’  compensation  and  pneumoconiosis  benefit 
obligations are determined using actuarial projection methods and numerous assumptions including claim development 

100 

 
 
  
 
 
 
 
 
 
patterns,  costs,  and  mortality.  The  estimates  rely  on  the  assumption  that  historical  claim  patterns  are  an  accurate 
representation for future claims.   

Our audit procedures related to the valuation of workers’ compensation and pneumoconiosis benefit obligations included 
the following, among others. 

•  We  tested  the  design  and  operating  effectiveness  of  controls  relating  to  the  workers’  compensation  and 
pneumoconiosis benefit obligations process including testing controls over management’s review of actuarial 
specialists' liability calculations and the completeness and accuracy of the underlying data. 

•  We tested management’s process for determining the worker’s compensation and pneumoconiosis benefit 
obligation accruals, including evaluating the reasonableness of the methods and significant assumptions used 
in the calculations with the assistance of actuarial specialists. 

•  We  tested  the  claims  data  used  in  the  actuarial  calculations  by  inspecting  source  documents  to  test  key 

attributes of the claims data. 

•  We  compared  claim  development  patterns  and  cost  assumptions  used  in  the  actuarial  calculations  for 

consistency with historical experience and current trends. 

•  We compared the mortality tables used in the actuarial calculations to publicly available information.

Organization 

ARLP  is  a  Delaware  limited  partnership  listed  on  the  NASDAQ  Global  Select  Market  under  the  ticker  symbol 
"ARLP." ARLP was formed in May 1999 and completed its initial public offering on August 19, 1999 when it acquired 
substantially all of the coal production and marketing assets of Alliance Resource Holdings, Inc., a Delaware corporation 
("ARH"), and its subsidiaries. We are managed by our general partner, MGP, a Delaware limited liability company, which 
holds a non-economic general partner interest in ARLP. Alliance GP, LLC ("AGP"), which is indirectly wholly owned by 
Mr. Craft, is the direct owner of MGP.  

Oil & Gas Acquisitions 

Boulders 

On  October  13,  2021,  we  acquired  approximately  1,480  oil  &  gas  net  royalty  acres  in  the  Delaware  Basin  from 

Boulders Royalty Corp. ("Boulders") for a purchase price of $31.0 million (the "Boulders Acquisition").  

Belvedere 

On  September  9,  2022,  we  acquired  approximately  394  oil  &  gas  net  royalty  acres  in  the  Delaware  Basin  from 

Belvedere Operating, LLC ("Belvedere") for a purchase price of $11.4 million (the "Belvedere Acquisition").  

Jase 

On October 26, 2022, we acquired approximately 3,928 oil & gas net royalty acres in the Midland and Delaware 

Basins from Jase Minerals, LP ("Jase") for a purchase price of $81.2 million (the "Jase Acquisition").  

JC Resources 

On February 22, 2023, we acquired approximately 2,682 oil & gas net royalty acres in the Delaware Basin from JC 
Resources LP ("JC Resources"), an entity owned by Mr. Craft, for $72.3 million, which was funded with cash on hand 
("JC Resources Acquisition"). Because JC Resources is owned by Mr. Craft, the JC Resources Acquisition is accounted 
for as a reorganization of entities under common control, whereby the assets and liabilities acquired from JC Resources 
are  combined  with  the  ARLP  Partnership  at  their  historical  amounts  for  all  periods  presented.  Recasting  for  the  JC 
Resources Acquisition increased revenues by $13.5 million and $9.3 million for the years ended December 31, 2022 and 

107 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
2021, respectively, and increased income from operations, net income and comprehensive income by $9.0 million and 
$4.6 million for the years ended December 31, 2022  and 2021, respectively. We did not recast historical earnings per 
limited partner unit as pre-acquisition earnings from the JC Resources Acquisition were allocated to our general partner.  

Skyland 

On December 7, 2023, we acquired approximately 2,372 oil & gas net royalty acres in the Anadarko, Williston and 
Delaware Basins from Skyland Minerals, L.P. ("Skyland") and Haymaker Minerals & Royalties II, LLC ("Haymaker") 
for a purchase price of $14.5 million which was funded with cash on hand ("Skyland Acquisition").  

The Boulders, Belvedere, Jase, JC Resources and Skyland Acquisitions enhanced our ownership position in various 
basins and furthered our business strategy to grow our Oil & Gas Royalties segment through accretive acquisitions. See 
Note 3 – Acquisitions for more information. We now hold approximately 67,700 net royalty acres in premier oil & gas 
resource plays including previous acquisitions and our investment in AllDale Minerals III, LP ("AllDale III").  

Growth Investments and Opportunities 

Francis 

On April 5, 2022, we invested $20 million in Francis Renewable Energy, LLC ("Francis"), in the form of a convertible 
note. Our convertible note matured on April 1, 2023 and was converted into a preferred equity interest in Francis. Francis 
currently is active in the installation, management and operation of metered-for-fee, public-access electric vehicle ("EV") 
charging  stations.  Francis  also  develops  and  constructs  EV  charging  stations  for  third-party  customers.  For  more 
information on this investment, please see Note 11 – Variable Interest Entities. 

Infinitum 

During  2022,  we  purchased  $42.0  million  of  Series  D  Preferred  Stock  in  Infinitum  Electric,  Inc.  ("Infinitum"),  a 
Texas-based startup developer and manufacturer of electric motors featuring printed circuit board stators which have the 
potential to result in motors that are smaller, lighter, quieter, more efficient and capable of operating at a fraction of the 
carbon footprint of conventional electric motors. On September 8, 2023, we purchased $24.6 million of Series E Preferred 
Stock ("Series E Preferred Stock" and, together with the "Series D Preferred Stock," the "Infinitum Preferred Stock") in 
Infinitum. The Infinitum Preferred Stock provides for non-cumulative dividends when and if declared by Infinitum's board 
of directors. Each share of Infinitum Preferred Stock is convertible, at any time, at our option, into shares of common stock 
of Infinitum. For more information on this investment, please see Note 12 – Equity Investments. 

NGP ET IV 

On June 2, 2022, we committed to purchase $25.0 million of limited partner interests in NGP Energy Transition, L.P. 
("NGP ET IV"), a private equity fund sponsored by NGP Energy Capital Management, LLC ("NGP"). NGP ET IV focuses 
on  investments  that  are  part  of  the  global  transition  toward  a  lower  carbon  economy  by  partnering  with  top-tier 
management teams and investing growth equity in companies that drive or enable the growth of renewable energy, the 
electrification of our economy or the efficient use of energy. For more information on this investment, please see Note 11 
– Variable Interest Entities. 

Ascend 

On  August  22,  2023,  we  purchased  $25.0  million  of  Series  D  Preferred  Stock  (the  "Ascend  Preferred  Stock")  in 
Ascend Elements, Inc. ("Ascend"), a U.S.-based manufacturer and recycler of sustainable, engineered battery materials 
for electric vehicles. The Ascend Preferred Stock provides for non-cumulative dividends when and if declared by Ascend's 
board of directors. Each share is convertible, at any time, at our option, into shares of common stock of Ascend. For more 
information on this investment please see Note 12 – Equity Investments. 

The Francis, Infinitum, NGP ET IV and Ascend investments further our business strategy to pursue opportunities that 
support the advancement of energy and related infrastructure and leverage our core competencies and build platforms for 
future lines of business with long-term growth and cash flow generation.

Change in Tax Status 

On March 15, 2022, Alliance Minerals changed its federal income tax status from a pass-through entity to a taxable 
entity  via  a  "check  the  box" election  (the  "Tax  Election"),  which  became  effective  January  1,  2022.  This  election  for 
Alliance Minerals reduced the total income tax burden on our oil & gas royalties, as Alliance Minerals now pays entity-
level taxes at corporate tax rates which are favorable to our unitholders. For more information on the Tax Election please 
see Note 7 – Income Taxes.  

Presentation 

The consolidated financial statements include the accounts and operations of the ARLP Partnership and present our 
financial position as of December 31, 2023 and 2022, and results of our operations, comprehensive income, cash flows 
and changes in partners' capital for each of the three years in the period ended December 31, 2023. All of our intercompany 
transactions and accounts have been eliminated.

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES 

Variable Interest Entity ("VIE") 

VIEs are primarily entities that lack sufficient equity to finance their activities without additional financial support 
from other parties or whose equity holders, as a group, lack one or more of the following characteristics: (a) direct or 
indirect ability to make decisions, (b) obligation to absorb expected losses or (c) right to receive expected residual returns. 
A VIE must be evaluated quantitatively and qualitatively to determine the primary beneficiary, which is the reporting 
entity that has (a) the power to direct activities of a VIE that most significantly impact the VIE's economic performance 
and (b) the obligation to absorb losses of the VIE that could potentially be significant to the VIE or the right to receive 
benefits from the VIE that could potentially be significant to the VIE. The primary beneficiary is required to consolidate 
the VIE for financial reporting purposes. 

To determine a VIE's primary beneficiary, we perform a qualitative assessment to determine which party, if any, has 
the power to direct activities of the VIE and the obligation to absorb losses and/or receive its benefits. This assessment 
involves identifying the activities that most significantly impact the VIE's economic performance and determine whether 
it, or another party, has the power to direct those activities. When evaluating whether we are the primary beneficiary of a 
VIE, we perform a qualitative analysis that considers the design of the VIE, the nature of our involvement and the variable 
interests held by other parties.  

Business Combinations 

A business consists of inputs and processes applied to those inputs that have the ability to contribute to the creation 
of outputs. We account for the acquisition of a business as a business combination, where we record the assets acquired, 
including identified intangible assets and liabilities assumed at their fair value, which in many instances involves estimates 
based on third-party valuations, such as appraisals, or internal valuations based on discounted cash flow analyses or other 
valuation  techniques.    However,  if  substantially  all  the  fair  value  of  the  assets  acquired  is  concentrated  in  a  single 
identifiable asset or a group of similar identifiable assets with the same risk profile, the acquisition is accounted for as an 
asset acquisition and recorded at cost. 

Estimates 

The preparation of consolidated financial statements in conformity with generally accepted accounting principles of 
the United States ("GAAP") requires management to make estimates and assumptions that affect the reported amounts and 
disclosures in the consolidated financial statements. Actual results could differ from those estimates. Significant estimates 
and assumptions include: 

•  Asset retirement obligations; 
•  Pension valuation variables; 
•  Workers' compensation and pneumoconiosis valuation variables;  
•  Acquisition related purchase price allocations;  
•  Life of mine assumptions; 

109 

 
 
 
 
 
 
 
 
 
 
 
 
•  Oil & gas reserve quantities and carrying amounts; and 
•  Determination of oil & gas revenue accruals 

Fair Value Measurements 

We apply fair value measurements to certain assets and liabilities. Fair value is defined as the price that would be 
received to sell an asset or paid to transfer a liability (an exit price) in an orderly transaction between market participants 
at the measurement date. Fair value is based on assumptions that market participants would use when pricing an asset or 
liability, including assumptions about risk and risks inherent in valuation techniques and inputs to valuations. Fair value 
measurements assume that the transaction occurs in the principal market for the asset or liability or, in the absence of a 
principal market, the most advantageous market for the asset or liability (the market for which the reporting entity would 
be  able  to  maximize  the  amount  received  or  minimize  the  amount  paid).  Valuation  techniques  used  in  our  fair  value 
measurements  are  based  on  observable  and  unobservable  inputs.  Observable  inputs  reflect  market  data  obtained  from 
independent sources, while unobservable inputs reflect our own market assumptions. 

We use the following fair value hierarchy, which prioritizes the inputs to valuation techniques used to measure fair 

value into three broad levels: 

•  Level 1 – Quoted prices for identical assets and liabilities in active markets that we have the ability to access 

at the measurement date. 

•  Level  2  –  Quoted  prices  for  similar  instruments  in  active  markets;  quoted  prices  for  identical  or  similar 
instruments  in  markets  that  are  not  active;  and  model  derived  valuations  whose  inputs  are  observable  or 
whose significant value drivers are observable. 

•  Level 3 – Unobservable inputs for the asset or liability including situations where there is little, if any, market 

activity for the asset or liability. 

The fair value hierarchy gives the highest priority to quoted prices in active markets (Level 1) and the lowest priority 
to unobservable data (Level 3). In some cases, the inputs used to measure fair value might fall into different levels of the 
fair value hierarchy. The lowest level input that is significant to a fair value measurement determines the applicable level 
in the fair value hierarchy. Assessing the significance of a particular input to the fair value measurement requires judgment, 
considering  factors  specific  to  the  asset  or  liability.  Significant  fair  value  measurements  are  used  in  our  significant 
estimates and are discussed throughout these notes. 

Cash and Cash Equivalents 

Cash and cash equivalents include cash on hand and on deposit, including highly liquid investments with maturities 
of three months or less. At times the ARLP Partnership maintains deposits in federally insured financial institutions in 
excess  of  stated  federally  insured  limits.  Management monitors  the  credit  ratings  and concentration  of  risk  with  these 
financial  institutions  on  a  continuing  basis  to  safeguard  cash  deposits.  Based  on  this  monitoring  and  other  diligence, 
including  discussions  with  representatives  of  the  financial  institutions,  we  have  no  reason  to  believe  that  any  of  the 
financial institutions in which we have deposits in excess of stated federally insured limits are facing financial difficulties, 
defaults or limited liquidity situations that would cause us to be unable to access our deposits. 

Cash Management 

The cash flows from operating activities section of our consolidated statements of cash flows reflects an adjustment 
for $6.7 million representing book overdrafts at December 31, 2023. We did not have material book overdrafts at December 
31, 2022 and 2021. 

Inventories 

Coal inventories are stated at the lower of cost or net realizable value on a first-in, first-out basis. Supply inventories 

are stated at an average cost basis, less a reserve for obsolete and surplus items.

Advance Royalties 

Rights to coal mineral leases are often acquired and/or maintained through advance royalty payments. Where royalty 
payments  represent  prepayments  recoupable  against  future  production,  they  are  recorded  as  an  asset,  with  amounts 
expected  to  be  recouped  within  one  year  classified  as  a  current  asset.  As  mining  occurs  on  these  leases,  the  royalty 
prepayments are charged to operating expenses. We assess the recoverability of royalty prepayments based on estimated 
future  production.  Royalty  prepayments  estimated  to  be  nonrecoverable  are  expensed.  Our  advance  royalties  are 
summarized as follows:

Property, Plant and Equipment 

Expenditures  which  extend  the  useful  lives  of  existing  plant  and  equipment  assets  are  capitalized.  Interest  costs 
associated with major asset additions are capitalized during the construction period. Maintenance and repairs that do not 
extend  the  useful  life  or  increase  productivity  of  the  asset  are  charged  to  operating  expense  as  incurred.  Exploration 
expenditures are charged to operating expense as incurred, including costs related to drilling and study costs incurred to 
convert or upgrade mineral resources to reserves. Processing facilities and mineral rights, assuming current production 
estimates,  are  depreciated  or  depleted  using  the  units-of-production  method.  Mining  equipment  and  other  plant  and 
equipment assets are depreciated principally using the straight-line method over the remaining estimated life of each mine. 
Buildings, office equipment and improvements are amortized straight line over their estimated useful lives. Gains or losses 
arising from retirements are included in operating expenses. Depletion of coal mineral rights is provided on the basis of 
tonnage mined in relation to estimated recoverable tonnage, which equals estimated proven and probable coal mineral 
reserves. Therefore, our coal mineral rights are depleted based on only proven and probable coal mineral reserves. See Oil 
& Gas Reserve Quantities and Carrying Amounts below for a discussion of our accounting policies for oil & gas properties. 

Mine Development Costs 

Mine development costs are capitalized until production, other than production incidental to the mine development 
process, commences and are amortized on a units of production method based on the estimated proven and probable coal 
mineral  reserves.  Mine development  costs  represent  costs  incurred  in  establishing  access  to  coal  mineral reserves  and 
include costs associated with sinking or driving shafts and underground drifts, permanent excavations, roads and tunnels.  
The end of the development phase and the beginning of the production phase takes place when construction of the mine 
for economic extraction is substantially complete. Coal extracted during the development phase is incidental to the mine's 
production capacity and is not considered to shift the mine into the production phase.   

Oil & Gas Reserve Quantities and Carrying Amounts 

We are wholly dependent on third-party operators to explore, develop, produce and operate the properties associated 
with our mineral interests. We follow the successful efforts method of accounting for our oil & gas mineral interests. Under 
this method, costs to acquire mineral interests in oil & gas properties are capitalized when incurred. The costs of mineral 
interests  in  unproved  properties  are  capitalized  pending  the  results  of  exploration  and  leasing  efforts  by operators.  As 
mineral interests in unproved properties are determined to be proved, the related costs are transferred to proved oil & gas 
properties.  

Mineral interests in oil & gas properties are grouped using a reasonable aggregation of properties with a common 
geological structural feature or stratigraphic condition, which we may also refer to as a depletable group. Mineral interests 
in proved oil & gas properties are depleted based on the units-of-production method. Proved reserves are quantities of oil 
& gas that can be estimated with reasonable certainty to be recoverable in the future from a given date forward, from 
known reservoirs, under existing economic conditions, operating methods, and government regulations. Proved developed

resources  are  the  quantities  expected  to  be  recovered  through  the  Operators'  existing  wells  with  existing  equipment, 
infrastructure and operating methods. 

We  evaluate  impairment  of  our  oil  &  gas  mineral  interests  in  proved  properties  whenever  events  or  changes  in 
circumstances indicate that the carrying amount of an asset may not be recoverable. This evaluation is performed on a 
depletable group basis. We compare the undiscounted projected future cash flows expected in connection with a depletable 
group to its unamortized carrying amount to determine recoverability. When the carrying amount of a depletable group 
exceeds  its  estimated  undiscounted  future  cash  flows,  the  carrying  amount  is  written  down  to  its  fair  value,  which  is 
measured as the present value of the projected future cash flows of such properties. The factors used to determine fair 
value include estimates of proved reserves, future commodity prices, timing of future production, future expenditures, and 
a risk-adjusted discount rate. 

Our  oil  &  gas  mineral  interests  in  unproved  properties  are  also  assessed  for  impairment  periodically  but  at  least 
annually when facts and circumstances indicate that the unproved property will not be transferred to proved properties.  
Impairment of individual unproved properties whose acquisition costs are relatively significant are assessed on a property-
by-property basis, and an impairment loss is recognized if we determine that the unproved property will not be transferred 
to  proved  properties.  Impairment  of  unproved  properties  whose  acquisition  costs  are  not  individually  significant  are 
assessed on a group basis. Any amount of loss to be recognized and the amount of a valuation allowance needed to provide 
for impairment of those properties is determined by amortizing those properties in the aggregate on the basis of historical 
experience and other relevant information, such as the relative proportion of such properties on which proved reserves 
have been found in the past.  

Upon the sale of a complete depletable group, the book value thereof, less proceeds or salvage value, are charged to 
income. Upon the sale or retirement of an aggregation of interests which make up less than a complete depletable group, 
the proceeds are credited to accumulated depreciation, depletion and amortization, unless doing so would significantly 
alter  the  depreciation,  depletion  and  amortization  rate  of  the  depletable  group,  in  which  case  a  gain  or  loss  would  be 
recorded. 

Equity Investments 

Our investments and ownership interests in equity securities without readily determinable fair values in entities in 
which  we  do  not  have  a  controlling  financial  interest  or  significant  influence  are  accounted  for  using  a  measurement 
alternative other than fair value which is historical cost minus impairment, if any, plus or minus changes resulting from 
observable  price  changes  in  orderly  transactions  for  identical  or  similar  investments  of  the  same  entity.  Distributions 
received on those investments are recorded as income unless those distributions are considered a return on investment, in 
which  case  the  historical  cost  is  reduced.  We  account  for  our  ownership  interests  in  Infinitum  and  Ascend  as  equity 
securities  without  readily  determinable  fair  values.  See  Note  12  –  Equity  Investments  for  further  discussion  of  these 
investments.     

Our  investments  and  ownership  interests  in  entities  in  which  we  do  not  have  a  controlling  financial  interest  are 
accounted for under the equity method of accounting if we have the ability to exercise significant influence over the entity.  
Investments accounted for under the equity method are initially recorded at cost, and the difference between the basis of 
our investment and the underlying equity in the net assets of the joint venture at the investment date, if any, is amortized 
over the lives of the related assets that gave rise to the difference.  

In the event our ownership requires a disproportionate sharing of income or loss, we use the hypothetical liquidation 
at book value ("HLBV") method to determine the appropriate allocation of income or loss. Under the HLBV method, 
income or loss of the investee is allocated based on hypothetical amounts that each investor would be entitled to receive if 
the  net  assets  held  were  liquidated  at  book  value  at  the  end  of  each  period,  adjusted  for  any  contributions  made  and 
distributions received during the period. 

We hold equity method investments in AllDale III, Francis and NGP ET IV. See Note 11 – Variable Interest Entities 

and Note 12 – Equity Investments for further discussion of our equity method investments.  

We review our investments for impairment whenever events or changes in circumstances indicate a loss in the value 

of the investment may be other-than-temporary.

Leases 

We lease buildings and equipment under operating lease agreements that provide for the payment of minimum rentals.  
We also have noncancelable lease agreements with third parties for land and equipment under finance lease obligations.  
Some  of  our  arrangements  within  these  agreements  have  both  lease  and  non-lease  components,  which  are  generally 
accounted for separately. We have elected a practical expedient to account for lease and non-lease components as a single 
lease component for leases of buildings and office equipment. Our leases have approximate lease terms of 1 to 19 years, 
some of which include automatic renewals up to ten years, which are likely to be exercised and some of which include 
options to terminate the lease within one year. We also hold numerous mineral reserve leases with both related parties as 
well as third parties, none of which are accounted for as an operating lease or as a finance lease.  

We review each agreement to determine if an arrangement within the agreement contains a lease at the inception of 
an arrangement. Once an arrangement is determined to contain an operating or finance lease with a term greater than 12 
months, we recognize a lease liability for the obligation to make lease payments and a right-of-use asset for the right to 
use the underlying asset for the lease term based on the present value of lease payments over the lease term. The lease term 
includes all noncancelable periods defined in the lease as well as periods covered by options to extend the lease that we 
are reasonably certain to exercise. As an implicit borrowing rate cannot be determined under most of our leases, we use 
our incremental borrowing rate based on the information available at commencement date in determining the present value 
of lease payments. 

Expenses related to leases determined to be operating leases will be recognized on a straight-line basis over the lease 
term including any reasonably assured renewal periods, while those determined to be finance leases will be recognized 
following  a  front-loaded  expense  profile  in  which  interest  and  amortization  are  presented  separately  in  the  income 
statement.  The  determination  of  whether  a  lease  is  accounted  for  as  a  finance  lease  or  an  operating  lease  requires 
management to make estimates primarily about the fair value of the asset and its estimated economic useful life. 

Common Unit-Based Compensation 

We maintain the Long-Term Incentive Plan ("LTIP") for certain key employees and executive officers. Pursuant to 
the LTIP, unit awards of non-vested "phantom" or notional units, also referred to as "restricted units," may be granted, 
which, upon satisfaction of time and performance-based vesting requirements, entitle the LTIP participant to receive ARLP 
common units. Certain awards may also contain a minimum-value guarantee payable in ARLP common units or cash that 
would be paid regardless of whether or not the awards vest, as long as service requirements are met. Annual grant levels, 
vesting provisions and minimum-value guarantees of restricted units for designated participants are recommended by Mr. 
Craft, subject to review and approval by the compensation committee of our general partner ("Compensation Committee"). 
The vesting of all restricted units is subject to the satisfaction of certain financial tests. If it is not probable that the financial 
tests will be achieved for a particular grant of restricted units, any previously expensed amounts for that grant are reversed, 
and no future expense will be recognized for that grant. Assuming the financial tests are met, restricted units issued to 
LTIP participants generally cliff vest on January 1st of the third year following the issuance of such restricted units. We 
expect to settle restricted unit grants by issuing ARLP common units, except for the portion of the restricted units that will 
satisfy our tax withholding obligations. We account for forfeitures of non-vested restricted unit grants as they occur. As 
provided under  the  distribution  equivalent rights  ("DERs") provisions of  the  LTIP  and  the  terms of  the restricted  unit 
awards, all currently outstanding non-vested restricted units include contingent rights to receive quarterly distributions in 
cash or, at the discretion of the Compensation Committee, phantom units in lieu of cash credited to a bookkeeping account 
with a value equal to the cash distributions we make to unitholders during the vesting period. If it is not probable the 
financial tests for a particular grant of restricted units will be met, any previously paid DER amounts for that grant are 
reversed from Partners' Capital and recorded as compensation expense and any future DERs, for that grant, if any, will be 
recognized as compensation expense when paid. 

We have utilized the Supplemental Executive Retirement Plan ("SERP") to provide deferred compensation benefits 
for  certain  executive  officers.  All  allocations  made  to  participants  under  the  SERP  have  been  made  in  the  form  of 
"phantom" ARLP units. We intend to settle any distributions from the SERP in the form of ARLP common units. The 
SERP has been administered by the Compensation Committee. 

Our directors participate in the MGP Amended and Restated Deferred Compensation Plan for Directors ("Directors' 
Deferred  Compensation  Plan").  Pursuant  to  the  Directors'  Deferred  Compensation  Plan,  for  amounts  deferred  either 
automatically or at the election of the director, a notional account is established and credited with notional common units 

113 

 
 
 
 
 
 
 
of ARLP, described in the Directors' Deferred Compensation Plan as "phantom" units. We intend to settle any distributions 
from the Directors' Deferred Compensation Plan in the form of ARLP common units. 

For  both  the  SERP  and  Directors'  Deferred  Compensation  Plan,  when  quarterly  cash  distributions  are  made  with 
respect to ARLP common units, an amount equal to such quarterly distribution is credited to each participant's notional 
account as additional phantom units and recorded as compensation expense. All grants of phantom units under the SERP 
and Directors' Deferred Compensation Plan vest immediately. 

On December 14, 2023, the Compensation Committee and the Board of Directors approved the termination of the 
SERP and Directors' Deferred Compensation Plan, and authorized distribution of accounts on December 15, 2024 or as 
soon thereafter as practical.  The accounts will continue to accrue benefits in accordance with plan terms until distributed. 

The fair value of restricted common unit grants under the LTIP, SERP and the Directors' Deferred Compensation Plan 
are determined on the grant date of the award and recognized as compensation expense on a pro rata basis for LTIP and 
SERP awards, as appropriate, over the requisite service period. Compensation expense is fully recognized on the grant 
date  for  quarterly  distributions  credited  to  SERP  accounts  and  Directors'  Deferred  Compensation  Plan  awards.  The 
corresponding  liability  is  classified  as  equity  and  included  in  limited  partners'  capital  in  the  consolidated  financial 
statements.  

Workers' Compensation and Pneumoconiosis (Black Lung) Benefits 

We  are  liable  for  workers'  compensation  benefits  for  traumatic  injuries  and  benefits  for  black  lung  disease  (or 

pneumoconiosis). Both traumatic claims and pneumoconiosis benefits are covered through our self-insured programs.  

We  provide  income  replacement  and  medical  treatment  for  work-related  traumatic  injury  claims  as  required  by 
applicable state laws. Workers' compensation laws also compensate survivors of workers who suffer employment related 
deaths. Our liability for traumatic injury claims is the estimated present value of current workers' compensation benefits, 
based  on  our  actuarial  estimates.  Our  actuarial  calculations  are  based  on  a  blend  of  actuarial  projection  methods  and 
numerous assumptions including claim development patterns, mortality, medical costs and interest rates.  

Our pneumoconiosis benefits liability is calculated using the service cost method based on the actuarial present value 
of the estimated pneumoconiosis obligation. Our actuarial calculations are based on numerous assumptions including claim 
development patterns, medical costs and mortality. Actuarial gains or losses are amortized over the remaining service 
period of active miners.  

Pension Benefits 

The funded status of our pension benefit plan is recognized separately in our consolidated balance sheets as either an 
asset or liability. The funded status is the difference between the fair value of plan assets and the plan's benefit obligation. 
Pension obligations and net periodic benefit costs are actuarially determined and impacted by various assumptions and 
estimates  including  expected  return  on  assets,  discount  rates,  mortality  assumptions,  employee  turnover  rates  and 
retirement dates. We evaluate our assumptions periodically and make adjustments to these assumptions and the recorded 
liability as necessary.  

The discount rate is determined for our pension benefit plan based on an approach specific to our plan. The year end 
discount rate is determined considering a yield curve comprised of high-quality corporate bonds and the timing of the 
expected benefit cash flows. 

The  expected  long-term  rate  of  return  on  plan  assets  is  determined  based  on  broad  equity  and  bond  indices,  the 
investment goals and objectives, the target investment allocation and on the average annual total return for each asset class.  

Unrecognized actuarial gains and losses and unrecognized prior service costs and credits are deferred and recorded in 
accumulated other comprehensive loss until amortized as a component of net periodic benefit cost. Unrecognized actuarial 
gains and losses in excess of 10% of the greater of the benefit obligation or the market-related value of plan assets are 
amortized over the participants' average remaining future years of service.

Asset Retirement Obligations 

Our  coal  mining  operations  are  governed  by  various  state  statutes  and  the  Federal  Surface  Mining  Control  and 
Reclamation Act of 1977, which establish reclamation and mine closing standards. These regulations require, among other 
things,  restoration of property  in  accordance  with  specified  standards  and  an  approved reclamation  plan.  We  record  a 
liability  for  the  fair  value  of  the  estimated  cost  of  future  mine  asset  retirement  and  closing  procedures,  escalated  for 
inflation  then  discounted,  on  a  present  value  basis  in  the  period  incurred  or  acquired  and  a  corresponding  amount  is 
capitalized by increasing the carrying amount of the related long-lived asset. Those costs relate to permanently sealing 
portals at underground mines and to reclaiming the final pits and support surface acreage for both our underground mines 
and past surface mines. Examples of these types of costs, common to both types of mining, include, but are not limited to, 
removing  or  covering  refuse piles  and  settling ponds,  water  treatment  obligations,  and  dismantling  preparation  plants, 
other facilities and roadway infrastructure. Accounting for asset retirement obligations also requires depreciation of the 
capitalized  asset  retirement  cost  and  accretion  of  the  asset  retirement  obligation  over  time.  Depreciation  is  generally 
determined on a units-of-production basis and accretion is generally recognized over the life of the producing assets. As 
changes in estimates occur (such as mine plan revisions, changes in estimated costs or changes in anticipated timing of 
reclamation activities), the revisions to the obligation and asset are recognized at the appropriate credit-adjusted, risk-free 
interest  rate.  Federal  and  state  laws  require  bonds  to  secure  our  obligations  to  reclaim  lands  used  for  mining  and  are 
typically renewed on an annual basis.  

Coal Revenue Recognition 

Revenues from coal supply contracts with customers, which primarily relate to sales of thermal coal, are recognized 
at the point in time when control of the coal passes to the customer. We have determined that each ton of coal represents 
a separate and distinct performance obligation. Our coal supply contracts and other revenue contracts vary in length from 
short-term  to  long-term  sales  contracts  and  do  not  typically  have  significant  financing  components.  Transportation 
revenues represent the fulfillment costs incurred for the services provided to customers through third-party carriers and 
for  which  we  are  directly  reimbursed.  Other  revenues  primarily  consist  of  transloading  fees,  administrative  service 
revenues from our affiliates, mine safety services and products, other coal contract fees and other handling and service 
fees. Performance obligations under these contracts are typically satisfied upon transfer of control of the goods or services 
to our customer which is determined by the contract and could be upon shipment or upon delivery.  

The estimated transaction price from each of our contracts is based on the total amount of consideration we expect to 
be entitled to under the contract. Included in the transaction price for certain coal supply contracts is the impact of variable 
consideration,  including  quality  price  adjustments,  handling  services,  government  imposition  claims,  per  ton  price 
fluctuations based on certain coal sales price indices and anticipated payments in lieu of shipments. We have constrained 
the expected value of variable consideration in our estimation of transaction price and only included this consideration to 
the extent that it is probable that a significant revenue reversal will not occur. The estimated transaction price for each 
contract  is  allocated  to  our  performance  obligations  based  on  relative  standalone  selling  prices  determined  at  contract 
inception. Variable consideration is allocated to a specific part of the contract in many instances, such as if the variable 
consideration is based on production activities for coal delivered during a certain period or the outcome of a customer's 
ability to accept coal shipments over a certain period.  

Contract assets are recorded as trade receivables and reported separately in our consolidated balance sheet from other 
contract assets as title passes to the customer and our right to consideration becomes unconditional. Payments for coal 
shipments are typically due within two to four weeks of performance. We typically do not have material contract assets 
that are stated separately from trade receivables as our performance obligations are satisfied as control of the goods or 
services passes to the customer thereby granting us an unconditional right to receive consideration. Contract liabilities 
relate  to  consideration  received  in  advance  of  the  satisfaction  of  our  performance  obligations.  Contract  liabilities  are 
recognized as revenue at the point in time when control of the good or service passes to the customer. 

Oil & Gas Revenue Recognition 

Oil  &  gas  royalty  revenues  are  recognized  at  the  point  in  time  when  control  of  the  product  is  transferred  to  the 
purchaser by the lessee and collectability of the sales price is reasonably assured. Oil & gas are priced on the delivery date 
based on prevailing market prices with certain adjustments related to oil quality and physical location. The royalty we 
receive is tied to a market index, with certain adjustments based on, among other factors, whether a well connects to a 
gathering or transmission line, quality and heat content of the product, and prevailing supply and demand conditions. 

115 

 
 
 
 
 
 
 
We also periodically earn revenue from lease bonuses. We recognize lease bonus revenue when we execute a lease of 
our mineral interests to exploration and production companies. A lease agreement represents our contract with an operator, 
which is generally an exploration and production company. The contract will (a) generally transfer the rights to any oil or 
gas  discovered,  (b)  grant  us  a  right  to  a  specified  royalty  interest  from  the  operator,  and  (c)  require  the  operator  to 
commence drilling and complete operations within a specified time period. Control of the minerals transfers to the operator 
when the lease agreement is executed. At the time we execute the lease agreement, we expect to receive the lease bonus 
payment within a reasonable time, though in no case more than one year, such that we do not adjust the expected amount 
of consideration for the effects of any significant financing component.  

As a non-operator, we have limited visibility into the timing of when new wells start producing. In addition, production 
statements may not be received for 30 to 90 days or more after the date production is delivered. As a result, we are required 
to estimate the amount of production delivered to the purchaser and the price that will  be received for the sale of the 
product.  The  expected  sales  volumes  and  prices  from  our  properties  are  estimated  and  recorded  within  the  Trade 
receivables line item in our consolidated balance sheets. The difference between our estimates and the actual amounts 
received for oil & gas royalty revenue are immaterial and recorded in the month that payment is received from the third-
party purchaser unless new production information is received prior to the payment allowing us to update the estimate 
recorded. 

Income Taxes 

We are not a taxable entity for federal or state income tax purposes; the tax effect of our activities accrues to our 
unitholders. Although publicly traded partnerships as a general rule are taxed as corporations, we qualify for an exemption 
because at least 90% of our income consists of qualifying income, as defined in Section 7704(c) of the Internal Revenue 
Code. Net income for financial statement purposes may differ significantly from taxable income reportable to unitholders 
as a result of differences between the tax basis and financial reporting basis of assets and liabilities and the taxable income 
allocation  requirements  under  our  partnership  agreement.  Individual  unitholders  have  different  investment  bases 
depending  upon  the  timing  and  price  of  acquisition  of  their  partnership  units.  Furthermore,  each  unitholder's  tax 
accounting, which is partially dependent upon the unitholder's tax position, differs from the accounting followed in our 
consolidated financial statements. Accordingly, the aggregate difference in the basis of our net assets for financial and tax 
reporting  purposes  cannot  be  readily  determined  because  information  regarding  each  unitholder's  tax  attributes  in  our 
partnership is not available to us.  

Our subsidiary Alliance Minerals within our Oil & Gas Royalties segment and certain other subsidiaries within our 
Other, Corporate and Elimination category are subject to federal and state income taxes. We use the liability method of 
accounting for income taxes, under which deferred tax assets and liabilities are recognized for the future tax consequences 
of (i) temporary differences between the financial statement carrying amounts and the tax basis of existing assets and 
liabilities and (ii) operating losses and tax credit carryforwards. Deferred income tax assets and liabilities are based on 
enacted rates applicable to the future period when those temporary differences are expected to be recovered or settled. The 
effect of a change in tax status or a change in tax rates on deferred tax assets and liabilities is recognized in the period the 
change in status is elected or rate change is enacted. A valuation allowance is provided for deferred tax assets when it is 
more likely than not the deferred tax assets will not be realized.  

New Accounting Standards Issued and Not Yet Adopted 

In  November  2023,  the  Financial  Accounting  Standards  Board  ("FASB")  issued  Accounting  Standards  Update 
("ASU") 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures ("ASU 2023-07").  
ASU 2023-07 primarily requires enhanced disclosures about significant segment expenses regularly provided to the chief 
operating decision maker ("CODM"), the amount and composition of other segment items, and the title and position of the 
CODM. ASU 2023-07 is effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal 
years beginning after December 15, 2024 with early adoption permitted. We are currently evaluating the impact of adopting 
ASU 2023-07, but do not expect it to have a material effect on our consolidated financial statements.    

In  December  2023,  the  FASB  issued  ASU  2023-09,  Income  Taxes  (Topic  740):  Improvements  to  Income  Tax 
Disclosures ("ASU 2023-09"). ASU 2023-09 primarily requires enhanced disclosures to (1) disclose specific categories in 
the rate reconciliation, (2) disclose the amount of income taxes paid and expensed disaggregated by federal, state, and 
foreign taxes, with further disaggregation by individual jurisdictions if certain criteria are met, and (3) disclose income

is effective for fiscal years beginning after December 15, 2024, with early adoption permitted. We are currently evaluating 
the impact of adopting ASU 2023-09, but do not expect it to have a material effect on our consolidated financial statements.

ACQUISITIONS 

Boulders 

On  October  13,  2021,  we  acquired  approximately  1,480  oil  &  gas  net  royalty  acres  in  the  Delaware  Basin  from 
Boulders for a purchase price of $31.0 million, which was funded with cash on hand. This acquisition gives us increased 
exposure  to  a  prolific  area  of  the  Delaware  Basin  and  is  within  close  proximity  to  reserves  acquired  in  previous 
acquisitions. The acreage acquired in the Boulders Acquisition was mostly undeveloped. Because more than 90% of the 
mineral interests acquired in the acquisition represent undeveloped properties with a similar risk profile, including proved 
undeveloped, we have determined that the Boulders Acquisition should be accounted for as an asset acquisition.  

The following table summarizes the purchase price allocation of the assets acquired in the Boulders Acquisition:

On September 9, 2022 (the "Belvedere Acquisition Date"), we acquired approximately 394 oil & gas net royalty acres 
in the Delaware Basin from Belvedere for a cash purchase price of $11.4 million, which was funded with cash on hand. 
This acquisition gives us additional exposure to a productive area of the Delaware Basin and is within close proximity to 
reserves  that  we  currently  own.  Because  the  mineral  interests  acquired  in  the  Belvedere  Acquisition  include  royalty 
interests in both developed properties and undeveloped properties with different risk profiles, we have determined that the 
acquisition should be accounted for as a business combination and the underlying assets should be recorded at fair value 
as of the Belvedere Acquisition Date on our consolidated balance sheet.

The fair value of the mineral interests was determined using an income approach consisting of a discounted cash flow 
model. The assumptions used in the discounted cash flow model included estimated production, projected cash flows, 
forward oil & gas prices and risk adjusted discount rates. Certain assumptions used are not observable in active markets; 
therefore, the fair value measurements represent Level 3 fair value measurements.

On October 26, 2022 (the "Jase Acquisition Date"), we acquired approximately 3,928 oil & gas net royalty acres in 
the Midland and Delaware Basins from Jase for a cash purchase price of $81.2 million which was funded with cash on 
hand.  This  acquisition  further  enhanced  our  ownership  position  in  the  Permian  Basin.  Because  the  mineral  interests 
acquired in the Jase Acquisition include royalty interests in both developed properties and undeveloped properties with 
different risk profiles, we have determined that the acquisition should be accounted for as a business combination and the 
underlying assets should be recorded at fair value as of the Jase Acquisition Date on our consolidated balance sheet.

production during the period between the Jase Acquisition Date and the effective date of the agreement and observable 
sales prices during the period. Certain assumptions used are not observable in active markets; therefore, the fair value

On February 22, 2023, we completed the JC Resources Acquisition, which gives us increased exposure to a prolific 
area of the Delaware Basin that is within close proximity to reserves that we currently own. This acquisition was approved 
by the conflicts committee of MGP's board of directors, which is comprised entirely of independent directors. Because JC 
Resources is under common control with us, we recorded the acquisition at JC Resources' carrying value for each period 
presented. The carrying value of the mineral interests as well as related receivables and payables at February 22, 2023 was 
$65.0  million  inclusive  of  $25.4  million  and  $37.8  million  of  mineral  interests  in  proved  and  unproved  properties, 
respectively.  The  JC  Resources  Acquisition  increased  revenues  included  in  our  consolidated  statements  of  income  by 
$10.6 million for the year ended December 31, 2023.  

Acquisition Agreement 

On January 27, 2023, we entered into a one-year collaborative agreement with a third party, effective January 1, 2023, 
committing up to $35.0  million for the acquisition of oil & gas mineral interests in the Midland and Delaware Basins. 
Under the agreement, the third party assists us in the identification, evaluation, and acquisition of target oil & gas mineral 
interests. In exchange for these services, the third party receives a participation share, partially funded by the third party, 
and is paid a periodic management fee. As of December 31, 2023, we have purchased $6.5 million and $6.7 million of oil 
& gas mineral interests in proved and unproved properties, respectively, pursuant to this agreement. Management fees 
paid under this agreement have been immaterial. On February 19, 2024, we renewed this agreement for an additional one-
year term, committing up to $25.0 million. 

Skyland Acquisition 

On December 7, 2023 (the "Skyland Acquisition Date"), we acquired approximately 2,372 oil & gas net royalty acres 
in the Anadarko, Williston and Delaware Basins from Skyland and Haymaker for a cash purchase price of $14.5 million 
which was funded with cash on hand. This acquisition further enhanced our ownership position in these basins. Because 
the  mineral  interests  acquired  in  the  Skyland  Acquisition  include  royalty  interests  in  both  developed  properties  and 
undeveloped properties with different risk profiles, we have determined that the acquisition should be accounted for as a 
business combination and the underlying assets should be recorded at fair value as of the Skyland Acquisition Date on our 
consolidated balance sheet.

The table above includes lower of cost or net realizable value adjustments of $33.3 million. These adjustments are a 
result of lower coal sale prices and higher cost per ton primarily due to the impact of Mettiki's longwall being idle most of 
the  second  half  of  2023  due  to  delayed development of  a new  longwall  district,  Hamilton  experiencing disruptions  in 
production  due  to  a  longwall  move,  and  continuing  development  of  the  Henderson  County  mine  at  our  River  View

the years ended December 31, 2023, 2022 and 2021, respectively.  

At  December 31,  2023  and  2022,  land  and  coal  mineral  rights  above  include  $13.4  million  and  $29.9  million, 
respectively, of carrying value associated with coal mineral reserves and resources attributable to properties where we or 
a third party to which we lease coal mineral reserves  and resources are not currently engaged in mining operations or 
leasing  to  third  parties,  and  therefore,  the  coal  mineral  reserves  are  not  currently  being  depleted.  We  believe  that  the 
carrying value of these coal mineral reserves will be recovered.  

At December 31, 2023 and 2022, our oil & gas mineral interests noted in the table above include the carrying value 
of our unproved oil & gas mineral interests totaling $411.6 million and $422.7 million, respectively. We generally do not 
record depletion expense for our unproved oil & gas mineral interests; however, we do review for impairment as needed 
throughout the year.  

During  2023,  we  incurred  $44.4  million  in  mine  development  costs,  primarily  related  to  Tunnel  Ridge  and  the 
Henderson  County  mine  at  River  View  Coal,  LLC  ("River  View").  During  2022,  we  incurred  $11.3  million  in  mine 
development costs, primarily related to Hamilton and River View mine. All past capitalized mine development costs are 
associated with other mines that shifted to the production phase in past years and we are amortizing these costs accordingly. 
We believe that the carrying value of the past development costs will be recovered.

Credit Facility 

On January 13, 2023, Alliance Coal, as borrower, entered into a Credit Agreement (the "Credit Agreement") with 
various financial institutions. The Credit Agreement provides for a $425 million revolving credit facility, which includes 
a sublimit of $15.0 million for swingline borrowings and permits the issuance of letters of credit up to the full amount of 
$425 million (the "Revolving Credit Facility"), and for a term loan in an aggregate principal amount of $75 million (the 
"Term Loan"). The Credit Agreement matures on March 9, 2027, at which time the aggregate outstanding principal amount 
of  all  Revolving  Credit  Facility  advances  and  all  Term  Loan  advances  are  required  to  be  repaid  in  full.  The  Credit 
Agreement  will  instead  mature  on  January  30,  2025,  if  on  that  date  our  Senior  Notes,  as  discussed  below,  are  still 
outstanding and Alliance Coal does not have liquidity of at least $200 million. Interest is payable quarterly, with principal 
of the Term Loan due in quarterly installments equal to 6.25% of the original principal amount of the Term Loan beginning 
with the quarter ending June 30, 2023 and the balance payable at maturity. The Revolving Credit Facility replaces the 
$459.5 million revolving credit facility extended to the Intermediate Partnership under its Fifth Amended and Restated 
Credit Agreement, dated as of March 9, 2020. We incurred debt issuance costs during the year ended December 31, 2023 
of  $12.4  million  in  connection  with  the  Credit  Agreement.  These  debt  issuance  costs  are  deferred  and  amortized  as  a 
component of interest expense over the term of the Revolving Credit Facility. 

The Revolving Credit Facility is underwritten by a syndicate of eighteen financial institutions and the obligations of 
the lenders are individual obligations, which means the failure of one or more lenders to be able to fund its obligation does 
not  relieve  the  remaining  lenders  from  funding  their  obligations.  Based  on  our  diligence,  including  discussions  with 
representatives of certain of these financial institutions, as of December 31, 2023 we have no reason to believe that the 
banks within our syndicate are facing financial difficulties, defaults or limited liquidity situations that would cause them 
to be unable to fund their obligations under the Credit Agreement. However, should any of the banks in our syndicate 
experience  conditions  in  the  future  that  limit  their  ability  to  fund  their  obligations,  the  amount  available  under  the 
Revolving Credit Facility could be reduced. 

The Credit Agreement is guaranteed by ARLP and certain of its subsidiaries, including the Intermediate Partnership 
and most of the direct and indirect subsidiaries of Alliance Coal (the "Subsidiary Guarantors"). The Credit Agreement also 
is secured by substantially all of the assets of the Subsidiary Guarantors and Alliance Coal. Borrowings under the Credit 
Agreement bear interest, at our option, at either (i) an adjusted one-month, three-month or six-month term rate based on 
the secured overnight financing rate published by the Federal Reserve Bank of New York, plus the applicable margin or 
(ii) the base rate plus the applicable margin. The base rate is the highest of (i) the Overnight Bank Funding Rate plus 
0.50%, (ii) the Administrative Agent's prime rate, and (iii) the Daily Simple Secured Overnight Financing Rate plus 100 
basis  points.  The  applicable  margin  for  borrowings  under  the  Credit  Agreement  are  determined  by  reference  to  the 
Consolidated Debt to Consolidated Cash Flow Ratio. For borrowings under the Term Loan, we elected the three-month 
term rate, with applicable margin, which was  8.50% as of December 31, 2023. At December 31, 2023, we had $41.0 
million of letters of credit outstanding with $384.0 million available for borrowing under the Revolving Credit Facility.

We incurred an annual commitment fee of 0.50% on the undrawn portion of the Revolving Credit Facility. We utilize the 
Credit Agreement, as appropriate, for working capital requirements, capital expenditures and investments, scheduled debt 
payments and distribution payments. 

The Credit Agreement contains various restrictions affecting Alliance Coal and its subsidiaries, including, among 
other  things,  restrictions  on  incurrence  of  additional  indebtedness  and  liens,  sale  of  assets,  investments,  mergers  and 
consolidations and transactions with affiliates. In each case, these restrictions are subject to various exceptions. In addition, 
restrictions apply to cash distributions by Alliance Coal to the Intermediate Partnership if such distribution would result 
in exceeding a minimum fixed charge coverage ratio (as determined in the Credit Agreement) or in Alliance Coal having 
liquidity of less than $200 million. The Credit Agreement requires us to maintain (a) a debt of Alliance Coal to cash flow 
ratio of not more than 1.5 to 1.0, (b) a consolidated debt of Alliance Coal and the Intermediate Partnership to cash flow 
ratio of not more than 2.5 to 1.0 and (c) an interest coverage ratio of not less than 3.0 to 1.0, in each case, during the four 
most recently ended fiscal quarters. The debt of Alliance Coal to cash flow ratio, consolidated debt of Alliance Coal and 
the Intermediate Partnership to cash flow ratio, and interest coverage ratio were 0.08 to 1.0, 0.46 to 1.0 and 63.86 to 1.0, 
respectively, for the trailing twelve months ended December 31, 2023. We were in compliance with the covenants of the 
Credit Agreement as of December 31, 2023 and anticipate remaining in compliance with the covenants.  

Net restricted assets, as defined by the Securities and Exchange Commission, refers to the amount of our consolidated 
subsidiaries' net assets for which the ability to transfer funds to ARLP in the form of cash dividends, loans, advances, or 
transfers is restricted. As a result of the restrictions contained in the Credit Facility and its associated compliance ratios, 
the amount of our net restricted assets at December 31, 2023 was $797.2 million.  

Senior Notes 

On April 24, 2017, the Intermediate Partnership and Alliance Resource Finance Corporation (as co-issuer), a wholly 
owned subsidiary of the Intermediate Partnership ("Alliance Finance"), issued an aggregate principal amount of $400.0 
million of senior unsecured notes due 2025 ("Senior Notes") in a private placement to qualified institutional buyers. The 
Senior Notes have a term of eight years, maturing on May 1, 2025 and accrue interest at an annual rate of 7.5%. Interest 
is payable semi-annually in arrears on each May 1 and November 1. The indenture governing the Senior Notes contains 
customary terms, events of default and covenants relating to, among other things, the incurrence of debt, the payment of 
distributions or similar restricted payments, undertaking transactions with affiliates and limitations on asset sales. During 
the  year  ended  December  31,  2023,  we  repurchased  or  redeemed  $115.4  million  of  our  Senior  Notes.  The  gain  on 
extinguishment of the Senior Notes is immaterial.  

Accounts Receivable Securitization 

Certain direct and indirect wholly owned subsidiaries of our Intermediate Partnership were party to a $60.0 million 
accounts receivable securitization facility ("Securitization Facility"). Under the Securitization Facility, certain subsidiaries 
sell certain trade receivables on an ongoing basis to our Intermediate Partnership, which then sells the trade receivables to 
AROP  Funding,  LLC  ("AROP  Funding"),  a  wholly  owned  bankruptcy-remote  special  purpose  subsidiary  of  our 
Intermediate Partnership, which in turn borrows on a revolving basis up to $60.0 million secured by the trade receivables. 
After  the  sale,  Alliance  Coal,  as  servicer  of  the  assets,  collects  the  receivables  on  behalf  of  AROP  Funding.  The 
Securitization Facility bears interest based on a short-term bank yield index. On December 31, 2023, we had $11.7 million 
of letters of credit outstanding with $48.3 million available for borrowing under the Securitization Facility. The agreement 
governing the Securitization Facility contains customary terms and conditions, including limitations with regards to certain 
customer credit ratings. In January 2024, we extended the term of the Securitization Facility to January 2025 and increased 
the  borrowing  availability  under  the  facility  to  $90.0  million.  The  Securitization  Facility  was  previously  scheduled  to 
mature in January 2024. At December 31, 2023, we did not have any outstanding borrowings under the Securitization 
Facility.

November 2019 Equipment Financing 

On November 6, 2019, the Intermediate Partnership entered into an equipment financing arrangement accounted for 
as  debt,  wherein  the  Intermediate  Partnership  received  $53.1  million  in  exchange  for  conveying  its  interest  in  certain 
equipment owned indirectly by the Intermediate Partnership and entering into a master lease agreement for that equipment 
(the "November 2019 Equipment Financing"). The November 2019 Equipment Financing contained customary terms and 
events of default and an implicit interest rate of 4.75% and matured on November 6, 2023. Upon maturity, the equipment 
reverted to the Intermediate Partnership.  

June 2020 Equipment Financing 

On June 5, 2020, the Intermediate Partnership entered into an equipment financing arrangement accounted for as debt, 
wherein the Intermediate Partnership received $14.7 million in exchange for conveying its interest in certain equipment 
owned indirectly by the Intermediate Partnership and entering into a master lease agreement for that equipment (the "June 
2020 Equipment Financing"). The June 2020 Equipment Financing contains customary terms and events of default and 
provides for forty-eight monthly payments with an implicit interest rate of 6.1%, maturing on June 5, 2024. Upon maturity, 
the equipment will revert to the Intermediate Partnership.

We also have an agreement with a bank to provide additional letters of credit in an amount of $5.0 million to maintain 
surety  bonds  to  secure  certain  asset  retirement  obligations  and  our  obligations  for  workers'  compensation  benefits.  At 
December 31, 2023, we had $5.0 million in letters of credit outstanding under this agreement.

Alliance Minerals' Tax Election resulted in the recognition of an initial deferred tax liability of $37.3 million with 
a corresponding increase to income tax expense and reduction of net income for the year ended December 31, 2022. This 
reduction of net income equates to approximately $0.29 per basic and diluted limited partner unit. Recognition of the initial 
deferred tax liability and expense is primarily the result of the $177.0 million non-cash acquisition gain recognized in 2019 
related to the acquisition of the remaining interests in AllDale Minerals LP ("AllDale I") and AllDale Minerals II, LP 
("AllDale  II",  and  collectively  with  AllDale  I,  "AllDale  I  &  II")  (the  "Acquisition  Gain").  The  Acquisition  Gain  was

The effective income tax rates for our income tax expense for the year ended December 31, 2023 and 2021 are 
less than the federal statutory rate, primarily due to the portion of income not subject to income taxes. The effective income 
tax rate for our income tax expense for the year ended December 31, 2022 is less than the federal statutory rate, primarily 
due to the portion of income not subject to income taxes, partially offset by the effect of the Tax Election previously 
discussed.  

Significant components of deferred tax liabilities and deferred tax assets are as follows:

Deferred tax liabilities for property, plant and equipment are primarily the result of the Alliance Minerals' Tax 

Election and associated impact of the Acquisition Gain discussed above.  

Federal  and  state  loss  carryovers  and  credits  are  primarily  due  to  net  operating  losses  and  research  and 
development credits associated with the operations of other subsidiaries that are taxable for federal income tax purposes.  

Research and development expenses are required to be capitalized and amortized for U.S. tax purposes, resulting 
in a deferred tax asset. These expenses are primarily associated with the operations of other subsidiaries that are taxable 
for federal income tax purposes.

approximate fair value due to the short maturity of those instruments. 

The estimated fair value of our long-term debt, including current maturities, is based on interest rates that we believe 
are currently available to us in active markets for issuance of debt with similar terms and remaining maturities. See Note 
6 – Long-Term Debt for additional information on our long-term debt.

PARTNERS' CAPITAL 

Distributions 

Our available cash that is not used for unit repurchases may, at the discretion of our general partner, be distributed 
within 45 days after the end of each quarter to unitholders of record. Available cash is generally defined in the partnership 
agreement as all cash and cash equivalents on hand at the end of each quarter less reserves established by MGP in its 
reasonable discretion for future cash requirements. These reserves are retained to provide for the conduct of our business, 
the payment of debt principal and interest and to provide funds for future distributions. The following table summarizes 
the quarterly per unit distribution paid during each quarter of 2021 through 2023:

all our common units outstanding, which was paid on February 14, 2024 to all unitholders of record on February 7, 2024. 

Unit Repurchase Program 

In January 2023, the board of directors of MGP authorized a $93.5 million increase to the unit repurchase program, 
which had $6.5 million of available capacity as of December 31, 2022. As a result, we were authorized to repurchase up 
to a total of $100.0 million of ARLP common units. The program has no time limit and we may repurchase units from 
time to time in the open market or in other privately negotiated transactions. The unit repurchase program authorization 
does not obligate us to repurchase any dollar amount or number of units. During the year ended December 31, 2023, we 
repurchased and retired 929,842 units at an average unit price of $20.90 for an aggregate purchase price of $19.4 million, 
leaving $80.6 million remaining under the current authorization. Since inception of the unit repurchase program, we have 
repurchased  and  retired  6,390,446  units  at  an  average  unit  price  of  $17.67  for  an  aggregate  purchase  price  of  $112.9 
million. 

Other 

The noncontrolling interest in our consolidated balance sheets represents Bluegrass Minerals Management, LLC's 
("Bluegrass Minerals") ownership interest in Cavalier Minerals JV, LLC ("Cavalier Minerals"). Our accumulated other 
comprehensive loss consists of unrecognized actuarial gains and losses as well as unrecognized prior service costs related 
to our pension and pneumoconiosis benefits. See Note 11 – Variable Interest Entities, Note 15 – Employee Benefit Plans 
and Note 19 – Accrued Workers' Compensation and Pneumoconiosis Benefits for further information. 

11. 

VARIABLE INTEREST ENTITIES 

AllDale I & II and Cavalier Minerals 

We own the general partner interests and, including the limited partner interests we hold through our ownership in 
Cavalier Minerals, approximately 97% of the limited partner interests in AllDale I & II. As the general partner of AllDale 
I & II, we are entitled to receive 20.0% of all distributions from AllDale I & II with the remaining 80.0% allocated to 
limited partners based upon ownership percentages. 

Cavalier Minerals owns approximately 72% of the limited partner interests in AllDale I & II. We own the managing 
member  interest  and  a 96% member  interest  in  Cavalier Minerals.  Bluegrass  Minerals  owns  a  4%  member  interest in 
Cavalier Minerals and a profits interest which entitles it to receive distributions equal to 25% of all distributions (including 
in  liquidation)  after  all  members  have  recovered  their  investment.  All  members  have  recovered  their  investment  and 
Bluegrass Minerals began receiving its profits interest distributions in late 2022.  

We have concluded that AllDale I, AllDale II and Cavalier Minerals are VIEs which we consolidate as the primary 
beneficiary because we have the power to direct the activities that most significantly impact the economic performance of 
AllDale I, AllDale II and Cavalier Minerals in addition to having substantial equity ownership. 

Our share of Cavalier Minerals' investment in AllDale I & II is eliminated in consolidation and Bluegrass Minerals' 
investment in Cavalier Minerals is accounted for as noncontrolling ownership interest in our consolidated balance sheets. 
Additionally, earnings attributable to Bluegrass  Minerals are recognized as noncontrolling interest in our consolidated 
statements of income.

AllDale III owns oil & gas mineral interests in areas around the oil & gas mineral interests we own. Alliance Minerals 
owns a 13.9% limited partner interest in AllDale III. Alliance Minerals' investment in AllDale III is subject to a 25% 
profits interest for the general partner that is subject to a return hurdle equal to the greater of 125% of cumulative capital 
contributions and a 10% internal rate of return, and following an 80/20 "catch-up" provision for the general partner.  

We have concluded that AllDale III is a VIE that we do not consolidate because we are not the primary beneficiary 
and AllDale III is structured as a limited partnership with the limited partners (1) not having the ability to remove the 
general partner and (2) not participating significantly in the operational decisions. We are not the primary beneficiary of 
AllDale III because we do not have the power to direct the activities that most significantly impact AllDale III's economic 
performance. See Note 12 – Equity Investments for more information about the accounting for our investment in AllDale 
III. 

Francis 

On April 5, 2022, we invested $20 million in Francis, in the form of a convertible note. Our convertible note matured 
on April 1, 2023 and was converted into a preferred equity interest in Francis. Prior to conversion, we had determined the 
note more closely represented equity as opposed to debt. Therefore, we accounted for the convertible note as an equity 
contribution even though we did not participate in Francis' earnings or losses and were not eligible to receive distributions 
during the term of the note. Subsequent to the conversion on April 1, 2023, we participate in earnings and losses and are 
eligible to receive distributions. As of December 31, 2023, we held approximately 17.0% of Francis' equity.  

We have concluded that Francis is a VIE that we do not consolidate because we are not the primary beneficiary and 
Francis' management structure is similar to a limited partnership with the non-managing members (i) not having the ability 
to remove the managing member and (ii) not participating significantly in the operational decisions. We are not the primary 
beneficiary of Francis because we do not have the power to direct the activities that most significantly impact Francis's 
economic performance. See Note 12 – Equity Investments for more information about the accounting for our investment 
in Francis. 

NGP ET IV 

On June 2, 2022, we committed to purchase $25.0 million of limited partner interests in NGP ET IV, a private equity 
fund sponsored by NGP and focused on investments that are part of the global transition toward a lower carbon economy. 
This commitment represents a 3.6% interest in NGP ET IV. As of December 31, 2023, we have funded $6.6 million of 
this commitment. 

We have concluded that NGP ET IV is a VIE that we do not consolidate because we are not the primary beneficiary 
and NGP ET IV is structured as a limited partnership with limited partners (i) not having the ability to remove the general 
partner and (ii) not participating significantly in the operational decisions. We are not the primary beneficiary of NGP ET 
IV  because  we  do  not  have  the  power  to  direct  the  activities  that  most  significantly  impact  NGP  ET  IV's  economic 
performance. See Note 12 – Equity Investments for more information about the accounting for our investment in NGP ET 
IV.

We account for our ownership interest in the income or loss of Francis as an equity method investment. Prior to the 
conversion of our convertible note, we did not participate in Francis' earnings or losses; however, upon conversion on 
April 1, 2023 we began participating. As a development stage company, Francis depends primarily on capital contributions 
to meet its operating and debt obligations. We currently believe that the carrying value of our investment is recoverable; 
however, if Francis is unable to raise sufficient funds to continue its operations and meet its debt obligations, it could have 
an adverse effect on our investment. The changes in our equity method investment in Francis were as follows:

During 2022, we purchased $42.0 million of Series D Preferred Stock in Infinitum, a Texas-based startup developer 
and manufacturer of electric motors featuring printed circuit board stators. On September 8, 2023, we purchased $24.6 
million of Series E Preferred Stock in Infinitum. The Infinitum Preferred Stock provides for non-cumulative dividends 
when and if declared by Infinitum's board of directors. Each share of Infinitum Preferred Stock is convertible, at any time, 
at our option, into shares of common stock of Infinitum. We account for our ownership interest in Infinitum as an equity 
investment without a readily determinable fair value. Absent an observable price change, it is not practicable to estimate 
the fair value of our investment in Infinitum because of the lack of a quoted market price for our ownership interests. 
Therefore, we use a measurement alternative other than fair value to account for our investment.

Ascend 

On August 22, 2023, we purchased $25.0 million of Ascend Preferred Stock in Ascend, a U.S.-based manufacturer 
and recycler of sustainable, engineered battery materials for electric vehicles. The Ascend Preferred Stock provides for 
non-cumulative dividends when and if declared by Ascend's board of directors. Each share is convertible, at any time, at 
our  option,  into  shares  of  common  stock  of  Ascend.  We  account  for  our  ownership  interest  in  Ascend  as  an  equity 
investment without a readily determinable fair value. Absent an observable price change, it is not practicable to estimate 
the  fair  value  of  our  investment  in  Ascend  because  of  the  lack  of  a  quoted  market  price  for  our  ownership  interests.  
Therefore, we use a measurement alternative other than fair value to account for our investment.

EARNINGS PER LIMITED PARTNER UNIT 

We utilize the two-class method in calculating basic and diluted earnings per limited partner unit ("EPU"). Subsequent 
to the JC Resources Acquisition, which is discussed in more detail in Note 1 – Organization and Presentation, net income 
attributable  to  ARLP  is  allocated  to  limited  partners  and  participating  securities  with  nonforfeitable  distributions  or 
distribution equivalents, while net losses attributable to ARLP are allocated only to limited partners but not to participating 
securities. Prior to the JC Resources Acquisition, in addition to limited partners and participating securities allocations, 
amounts  are  also  allocated  to  our  general  partner  for historical  earnings  from  the  mineral  interests  acquired  in  the  JC 
Resources Acquisition. Our participating securities are outstanding restricted unit awards under our LTIP and phantom 
units in notional accounts under our SERP and the Directors' Deferred Compensation Plan.  

The following is a reconciliation of net income attributable to ARLP used for calculating basic and diluted earnings 

per unit and the weighted-average units used in computing EPU.

Diluted EPU excludes all potentially dilutive units calculated under the treasury stock method if their effect is anti-dilutive. For the 
years ended December 31, 2023, 2022 and 2021, the combined total of LTIP, SERP and Directors' Deferred Compensation Plan 
units of 2,922,384, 3,540,385 and 1,967,672, respectively, were considered anti-dilutive under the treasury stock method.

EMPLOYEE BENEFIT PLANS 

Defined Contribution Plans 

All regular full-time employees are eligible to participate in a defined contribution profit sharing and savings plan 
("PSSP")  that  we  sponsor.  PSSP  participants  may  elect  to  make  voluntary  contributions  to  this  plan  up  to  a  specified 
amount of their compensation. We make matching contributions based on a percent of an employee's eligible compensation 
and also make an additional non-matching contribution. Our contribution expense for the PSSP was approximately $21.8 
million, $19.4 million and $17.7 million for the years ended December 31, 2023, 2022 and 2021, respectively. 

Defined Benefit Plan 

Eligible employees and former employees of certain of our mining operations participate in a defined benefit plan (the 
"Pension Plan") that we sponsor. The Pension Plan is closed to new applicants. Participants in the Pension Plan are no 
longer receiving benefit accruals for service. The benefit formula for the Pension Plan is a fixed-dollar unit based on years 
of service. 

The following sets forth changes in benefit obligations and plan assets for the years ended December 31, 2023 and 
2022  and  the  funded  status  of  the  Pension  Plan  reconciled  with  the  amounts  reported  in  our  consolidated  financial 
statements: 

Change in benefit obligations: 

Benefit obligations at beginning of year 
Interest cost 
Actuarial loss (gain)

The actuarial loss component of the change in benefit obligations in 2023 was primarily attributable to a decrease in 
the discount rate compared to the prior year end. The actuarial gain component of the change in benefit obligations in 2022 
was primarily attributable to an increase in the discount rate compared to the prior year end.  

The expected long-term rate of return used to determine our pension liability is based on an asset allocation assumption

We do not expect to make material contributions to the Pension Plan during 2024. 

The Compensation Committee has appointed an investment manager with full investment authority with respect to 
Pension Plan investments subject to investment guidelines and compliance with Employee Retirement Income Security 
Act of 1974 or other applicable laws. The investment manager employs an asset allocation strategy through investment in 
certain investment types such as equity securities and fixed income securities. The asset allocation process provides that 
the  total  portfolio  allocation  will  be  adjusted  as  the  funded  ratio  of  the  plan  changes  and  market  conditions  warrant, 
consistent with managing risks in accordance with plan objectives and time horizon. As the funded ratio improves, more 
assets may be allocated to the core fixed income portfolio to reduce volatility. The objective of the allocation policy is to 
achieve an average annual return greater than the actuarial discount rate over the specified time horizon. General asset 
allocation guidelines at December 31, 2023 are as follows: 

Equity securities 
Fixed income securities 

  Percentage of Total Portfolio   
      Maximum    
      Minimum 

50%  
15%  

85%  
50%  

Equity  securities  include  domestic  and  international  common  stocks,  convertible  notes  and  bonds,  convertible 
preferred stocks, American Depository Receipts of non-U.S. companies and Real Estate Investment Trusts. Fixed income 
securities  include  debt  securities  issued  by  the  federal  government  as  well  as  state  and  local  governments,  banker's 
acceptances,  repurchase  agreements,  asset-backed  securities,  collateralized  mortgage-backed  securities,  corporate  debt 
securities, inflation-index bonds and structured notes.

(a)  Equity  investments  -  Individual  securities  include  investments  in  publicly  traded  common  stock  and  American 
Depository Receipts. Publicly traded common stocks are traded on a national securities exchange and investments in 
common  stocks  are  valued  using  quoted  market  prices  multiplied  by  the  number  of  shares  owned.  American 
Depository Receipts are negotiable securities issued by a bank representing shares in a foreign company and traded 
on a national securities exchange. 

(b)  Fixed income investments - Individual securities include investments in preferred stock that are traded on a national 

securities exchange and valued using quoted market prices multiplied by the number of shares owned. 

(c)  Equity investments - Mutual funds are valued daily in actively traded markets. For purposes of calculating the value, 
portfolio  securities  and  other  assets  for  which  market  quotes  are  readily  available  are  valued  at  market  value. 
Investments initially valued in currencies other than the U.S. dollars are converted to the U.S. dollar using exchange 
rates obtained from pricing services. 

(d)  Equity investments – Exchange traded funds are funds that own financial assets and trade on exchanges, generally 
tracking a specific index. Investments in exchange traded funds are valued using a market approach based on the 
quoted market prices. 

(e)  Accrued income represents dividends or interest declared, but not received, on equity securities owned at December 

31, 2023.

(f)  Investments measured at fair value using the net asset value per share (or its equivalent) have not been classified 
within the fair value hierarchy. The fair values of all commingled investment funds are determined based on the net 
asset values per unit of each of the funds. The net asset values per unit represent the aggregate value of the fund's 
assets at fair value less liabilities, divided by the number of units outstanding.

(1)  Restricted units granted have certain minimum-value guarantees per unit, regardless of whether or not the awards 

vest. 

(2)  During the year ended December 31, 2023, we issued 860,060 unrestricted common units to the LTIP participants. 

The remaining vested units were settled in cash to satisfy our tax withholding obligations. 

For the years ended December 31, 2023, 2022 and 2021, our LTIP expense for grants of restricted units was $10.4 
million, $9.4 million and $5.4 million, respectively. The total obligation associated with LTIP grants of restricted units as 
of December 31, 2023 and 2022 was $19.5 million and $16.0 million, respectively, and is included in the partners' capital 
Limited partners-common unitholders line item in our consolidated balance sheets. As of December 31, 2023, there was 
$10.0 million in total unrecognized compensation expense related to the non-vested LTIP restricted unit grants that are 
expected to vest. That expense is expected to be recognized over a weighted-average period of 1.4 years. 

On January 24, 2024, the Compensation Committee authorized additional grants of 440,470 restricted units, of which 
425,470 units were granted. These restricted units have certain minimum-value guarantees, regardless of whether or not 
the awards vest.

  $ 

For the year ended December 31, 2023, the allocation of liability associated with mine development and change in 

assumptions decreased by $1.5 million. The decrease was largely attributable to lower cost assumptions. 

For the year ended December 31, 2022, the allocation of liability associated with mine development and change in 
assumptions increased by $17.4 million. The increase was largely attributable to higher cost assumptions as well as the 
expansion of refuse disposal facilities at certain mines. 

The impact of discounting our estimated cash flows resulted in reducing the accrual for asset retirement obligations 
by  $116.2  million  and  $110.4  million  at  December 31,  2023  and  2022,  respectively.  Estimated  payments  of  asset

The discount rate used to calculate the estimated present value of future obligations for workers' compensation was 

4.66% and 4.87% at December 31, 2023 and 2022, respectively. 

The valuation gain in 2023 was primarily attributable to a favorable change in claims development partially offset by 
a decrease in the discount rate used to calculate the estimated present value of the future obligations. The valuation loss in 
2022 was primarily attributable to an increase in the discount rate used to calculate the estimated present value of the future 
obligations being partially offset by unfavorable changes in claims development. 

As of December 31, 2023 and 2022, we had $99.4 million and $99.8 million, respectively, in surety bonds and letters 

of credit outstanding to secure workers' compensation obligations. 

We limit our exposure to traumatic injury claims by purchasing a high deductible insurance policy that starts paying 
benefits  after  deductibles  for  the  particular  claim  year  have  been  met.  Our  workers'  compensation  liability  above  is 
presented on a gross basis and does not include our expected receivables on our insurance policy. Our receivables for 
traumatic  injury  claims  under  this  policy  as  of  December  31,  2023  and  2022  were  $4.1  million.  Our  receivables  are 
included in Other long-term assets on our consolidated balance sheets.

The actuarial loss component of the change in benefit obligations in 2023 was primarily attributable to a) unfavorable 
changes  in  the  discount  rate,  b)  unfavorable  demographics  in  the  at-risk  population,  c) unfavorable  black  lung  claims 
experience, d) unfavorable assumption changes regarding future average medical benefits, and e) unfavorable assumption 
changes related to Federal and State benefit levels. The actuarial gain component of the change in benefit obligations in 
2022  was  primarily  attributable  to  favorable  assumption  changes  in  the  discount  rate  and  demographics  in  the  at-risk 
population.  These  components  were  offset  in  part  by  a)  unfavorable  black  lung  claims  experience,  b)  unfavorable 
assumption changes regarding future average medical benefits and legal expense levels, and c) unfavorable assumption 
changes related to Federal and State benefit levels.

RELATED-PARTY TRANSACTIONS 

We have continuing related-party transactions with MGP and its affiliates. The Board of Directors and its conflicts 
committee  ("Conflicts  Committee")  review  our  related-party  transactions  that  involve  a  potential  conflict  of  interest 
between our general partner or its affiliates and ARLP or its subsidiaries or any other partner of ARLP to determine that 
such transactions are fair and reasonable to ARLP. As a result of these reviews, the Board of Directors and the Conflicts 
Committee  approved  each  of  the  transactions  described  below  that  had  such  potential  conflict  of  interest  as  fair  and 
reasonable to ARLP. 

Line of Credit 

On February 19, 2021, we entered into a line of credit arrangement (the "Line of Credit") with a related party for $5.0 
million. This Line of Credit was amended on November 4, 2021 to increase the total available under the Line of Credit to 
$5.5 million. The Line of Credit had a maturity date of February 28, 2023 and accrued interest at an annual rate of 3.5% 
payable quarterly. During the year ended December 31, 2021 we received proceeds and made payments under the Line of 
Credit of $5.3 million. On November 10, 2021 we terminated the Line of Credit.

Craft Foundations 

In January 2005, we acquired Tunnel Ridge from ARH. In connection with this acquisition, we assumed a coal lease 
with  Alliance  Resource  GP,  LLC,  an  entity  indirectly  wholly  owned  by  Mr.  Craft  and  Kathleen  S.  Craft  until  it  was 
dissolved in December 2020. In December 2018, the property subject to the lease was transferred to the Joseph W. Craft 
III  Foundation  and  the  Kathleen  S.  Craft  Foundation,  which  each  hold  an  undivided  one-half  interest  (the  "Craft 
Foundations"). Under the terms of the lease, Tunnel Ridge is required to pay an annual minimum royalty of $3.0 million. 
The lease expires the earlier of January 1, 2033 or upon the exhaustion of the mineable and merchantable leased coal.  
Tunnel  Ridge  incurred  $12.1  million,  $12.3  million  and  $5.8  million  in  earned  royalties  in  2023,  2022  and  2021 
respectively.  

Tunnel Ridge has a surface land lease with an annual payment of $0.2 million, payable in January of each year with 

the Craft Foundations. 

WKY CoalPlay 

In  February  2015,  WKY  CoalPlay,  LLC  ("WKY  CoalPlay")  entered  into  a  coal  lease  agreement  with  Alliance 
Resource Properties regarding coal mineral resources located in Henderson and Union Counties, Kentucky. The lease has 
an initial term of 20 years and provides for earned royalty payments to WKY CoalPlay of 4.0% of the coal sales price and 
annual minimum royalty payments of $2.1 million. All annual minimum royalty payments are recoupable from future 
earned royalties.  

In December 2014, WKY CoalPlay's subsidiaries, Towhead Coal Reserves, LLC and Henderson Coal Reserves, LLC 
entered into coal lease agreements with Alliance Resource Properties. The leases have initial terms of 20 years and provide 
for earned royalty payments of 4.0% of the coal sales price and annual minimum royalty payments of $3.6 million and 
$2.5 million, respectively. All annual minimum royalty payments under each agreement are recoupable from future earned 
royalties payable under that agreement.

In December 2014, WKY CoalPlay's subsidiary, Webster Coal Reserves, LLC entered into a coal lease agreement 
with Alliance Resource Properties. The lease had a term of 7 years and provided for earned royalty payments of 4.0% of 
the coal sales price and annual minimum royalty payments of $2.6 million. This lease expired in December 2021.  

21. 

COMMITMENTS AND CONTINGENCIES 

Commitments 

We lease buildings and equipment under operating lease agreements that provide for the payment of both minimum 
and contingent rentals. We also have noncancelable coal mineral reserve and resource leases as discussed in Note 20 – 
Related-Party Transactions.  

Contractual Commitments 

In connection with planned capital projects, we have contractual commitments of approximately $201.9 million at 
December 31,  2023.  As  of  December 31,  2023,  we  had $22.3  million  in  commitments  to  purchase  coal  from  external 
production sources in 2024 and thereafter. 

General Litigation 

Certain of our subsidiaries are party to litigation in which the plaintiffs allege violations of the Fair Labor Standards 
Act and state law due to alleged failure to compensate for time "donning" and "doffing" equipment and to account for 
certain bonuses in the calculation of overtime rates and pay. The plaintiffs seek class and collective action certification, 
which  we  oppose,  and  the  courts  have  not  yet  made  definitive  final  rulings  on  those  issues.  We  believe  our  ultimate 
exposure, if any, will not be material to our results of operations or financial position; however, if our current belief as to 
the merit of the claims is not upheld, it is reasonably possible that the ultimate resolution of these matters could result in a 
potential loss that may be material to our results of operations. 

We also have various other lawsuits, claims and regulatory proceedings incidental to our business that are pending 
against the ARLP Partnership. We record an accrual for a potential loss related to these matters when, in management's 
opinion, such loss is probable and reasonably estimable. Based on known facts and circumstances, we believe the ultimate 
outcome of these outstanding lawsuits, claims and regulatory proceedings will not have a material adverse effect on our 
financial  condition,  results  of  operations  or  liquidity.  However,  if  the  results  of  these  matters  are  different  from 
management's current expectations, such matters could have a material adverse effect on our business and operations. 

Other 

Effective October 1, 2023, we renewed our property and casualty insurance program through September 30, 2024. 
Our  property  insurance  was  procured  from  our  wholly  owned  captive  insurance  company,  Wildcat  Insurance,  LLC 
("Wildcat Insurance"). Wildcat Insurance charged certain of our subsidiaries for the premiums on this program and in 
return purchased  reinsurance for  the  program  in  the  standard  market.  The  maximum  limit  in  the  commercial property 
program is $100.0 million per occurrence, excluding a $1.5 million deductible for property damage, a 75 or 90 day waiting 
period for underground business interruption depending on the mining complex and an additional $25.0 million overall 
aggregate deductible. We retained a 7.25% participating interest in our current commercial property insurance program. 
We can make no assurances that we will not experience significant insurance claims in the future that could have a material 
adverse effect on our business, financial condition, results of operations and ability to purchase property insurance in the 
future. Also, exposures exist for which no insurance may be available and for which we have not reserved. In addition, the 
insurance  industry  has  been  subject  to  efforts  by  environmental  activists  to  restrict  coverages  available  for  fossil-fuel 
companies.  

22. 

CONCENTRATION OF CREDIT RISK AND MAJOR CUSTOMERS 

The international coal market has been a part of our business with indirect sales to end-users in Europe, Africa, Asia, 
North  America  and  South  America.  Our  sales  into  the  international  coal  market  are  considered  exports  and  are  made 
through  brokered  transactions.  During  the  years  ended  December  31,  2023,  2022  and  2021,  export  tons  represented 
approximately 15.7%, 12.5% and 12.5% of tons sold, respectively.  

144 

 
 
 
 
 
 
 
 
 
 
 
 
 
Because title to our export shipments typically transfers to our brokerage customers at a point that does not necessarily 
reflect  the  end-usage  point,  we  attribute  export  tons  to  the country  with  the  end-usage  point,  if known.  No  individual 
country was attributed greater than 10% of total domestic and export tons sold during the years ended December 31, 2023, 
2022 and 2021.  

We have significant long-term coal supply agreements, some of which contain prospective price adjustment provisions 
designed to reflect changes in market conditions, labor and other production costs and, in the infrequent circumstance 
when the coal is sold other than free on board the mine, changes in transportation rates. A major customer is defined as a 
customer from which we derive at least ten percent of our total revenues, including transportation revenues. Total revenues 
from major customers are as follows:

Trade accounts receivable from major customers totaled approximately $54.3 million and $63.6 million at December 
31, 2023 and 2022, respectively. Our credit loss experience has historically been insignificant. Financial conditions of our 
customers could result in a material change to our credit loss expense in future periods. The coal supply agreements with 
Customers A and B expire in 2025 and 2029, respectively.

SEGMENT INFORMATION 

We operate in the United States as a diversified natural resource company that generates operating and royalty income 
from the production and marketing of coal to major domestic and international utilities and industrial users as well as 
royalty income from oil & gas mineral interests. We aggregate multiple operating segments into four reportable segments, 
Illinois Basin Coal Operations, Appalachia Coal Operations, Oil & Gas Royalties and Coal Royalties. We also have an 
"all  other"  category  referred  to  as  Other,  Corporate  and  Elimination.  Our  two  coal  operations  reportable  segments 
correspond to major coal producing regions in the eastern United States with similar economic characteristics including 
coal quality, geology, coal marketing opportunities, mining and transportation methods and regulatory issues. The two 
coal operations reportable segments include seven mining complexes operating in Illinois, Indiana, Kentucky, Maryland, 
Pennsylvania,  and  West  Virginia  and  a  coal  loading  terminal  in  Indiana on  the  Ohio  River.  Our  Oil  &  Gas  Royalties 
reportable segment includes our oil & gas mineral interests which are located primarily in the Permian (Delaware and 
Midland), Anadarko (SCOOP/STACK) and Williston (Bakken) basins. The operations within our Oil & Gas Royalties 
reportable segment primarily include receiving royalties and lease bonuses for our oil & gas mineral interests. Our Coal 
Royalties  reportable  segment  includes  coal  mineral  reserves  and  resources  owned  or  leased  by  Alliance  Resource 
Properties, which are either (a) leased to our mining complexes or (b) near our coal mining operations but not yet leased.  

The Illinois Basin Coal Operations reportable segment includes (a) the Gibson County Coal, LLC's ("Gibson ") mining 
complex, (b) the Warrior Coal, LLC ("Warrior") mining complex, (c) the River View mining complex and (d) the Hamilton 
mining complex. The segment also includes our Mt. Vernon Transfer Terminal, LLC ("Mt. Vernon") coal loading terminal 
in Indiana which operates on the Ohio River, Mid-America Carbonates, LLC ("MAC") and other support services, and 
our non-operating mining complexes.  

The Appalachia Coal Operations reportable segment includes (a) the Mettiki mining complex, (b) the Tunnel Ridge 

mining complex and (c) the MC Mining, LLC ("MC Mining") mining complex.  

The Oil & Gas Royalties reportable segment includes oil & gas mineral interests held by Alliance Minerals' through 

its consolidated subsidiaries as well as equity interests held in AllDale III (Note 12 – Equity Investments).  

Coal Royalties reportable segment includes coal mineral reserves and resources owned or leased by Alliance Resource 
Properties that are (a) leased to certain of our mining complexes in both the Illinois Basin Coal Operations and Appalachia

Coal Operations reportable segments or (b) located near our operations and external mining operations. Approximately 
60% of the coal sold by our coal operations' mines was leased from our Coal Royalties entities.  

Other, Corporate and Elimination includes marketing and administrative activities, Matrix Design Group, LLC, its 
subsidiaries, and Alliance Design Group, LLC (collectively referred to as the "Matrix Group"), our investments in Francis, 
Infinitum,  NGP  ET  IV  and  Ascend  (see  Note  12  –  Equity  Investments),  Wildcat  Insurance,  which  assists  the  ARLP 
Partnership with its insurance requirements, AROP Funding and Alliance Finance (both discussed in Note 6 – Long-Term 
Debt)  and  other  miscellaneous  activities.  The  eliminations  included  in  Other,  Corporate  and  Elimination  primarily 
represent the intercompany coal royalty transactions described above between our Coal Royalties reportable segment and 
our coal operations' mines. 

Reportable segment results are presented below.

(3)  Segment Adjusted EBITDA is defined as net income attributable to ARLP before net interest expense, income taxes, 
depreciation, depletion and amortization and general and administrative expense. Management therefore is able to 
focus solely on the evaluation of segment operating profitability as it relates to our revenues and operating expenses, 
which  are  primarily  controlled  by  our  segments.  Net  income,  the  most  comparable  GAAP  financial  measure,  is

SUPPLEMENTAL OIL & GAS RESERVE INFORMATION (UNAUDITED) 

All periods presented in these supplemental oil & gas reserve information disclosures have been recast to reflect the 
JC Resources Acquisition as if we, rather than JC Resources, acquired the mineral interests in 2019. For more information 
with respect to the JC Resources Acquisition please see Note – 1 Organization and Presentation and Note – 3 Acquisition 
in our consolidated financial statements.  

Geographical Area of Operation 

All of our proved oil & gas reserves are located within the continental United States with the majority concentrated 
in Texas, Oklahoma, New Mexico and North Dakota. The following supplemental disclosures about our proved oil & gas 
reserves including costs incurred, capitalized cost, results of operations and cash flows are presented on a consolidated 
basis.

Natural gas reserves are converted to BOE based on a 6:1 ratio: six Mcf of natural gas converts to one BOE. 

Notable changes in proved reserves during the year ended December 31, 2021, included: 

•  Net  change  due  to  extensions  and  discoveries  -  The  increases  are  a  result  of  additional  development  by  the 
operators of the properties under which we own mineral interests. In 2021, a net addition of 1,358 MBOE occurred 
primarily  from  the  completion  of  906  new  wells  on  our  acreage  and  from  the  addition  of  498  new  proved 
undeveloped locations due to permitting and drilling activity. 

•  Revisions - Increases in oil & gas are also due to changes in the underlying commodity prices during the year and 

revisions of previous quantity estimates.

Standardized Measure of Discounted Future Net Cash Flows  

Future cash inflows represent expected revenues from production of period-end quantities of proved reserves based 
on the 12-month unweighted average of first-of-the-month commodity prices for the years ended December 31, 2023, 
2022 and 2021. All prices are adjusted for quality, transportation fees, energy content and regional basis differentials. 
Future cash inflows are computed by applying applicable prices relating to our proved reserves to the year-end quantities 
of those reserves. Future production costs are derived based on current costs assuming continuation of existing economic 
conditions.   

While due care was taken in preparation of the following cash flow projections, we do not represent that this data is 
the fair value of our oil & gas properties, or a fair estimate of the present value of cash flows to be obtained from their 
development and production. Material revisions to estimates of proved reserves may occur in the future; development and 
production of the reserves may not occur in the periods assumed; actual prices are expected to vary significantly from 
those used and actual costs may vary.

NOTES TO FINANCIAL INFORMATION (PARENT) 

1. 

BASIS OF PRESENTATION 

In these parent-company-only financial statements, our investment in consolidated subsidiaries is stated at cost plus 
equity in undistributed earnings of subsidiaries and reduced by distributions received from subsidiaries since the date of 
acquisition.  These parent-company-only financial statements have been recast as a result of the JC Resources Acquisition 
as discussed in "Item 8. Financial Statements and Supplementary Data—Note 1 – Organization and Presentation" of this 
Annual Report on Form 10-K.  These parent-company-only financial statements should be read in conjunction with our 
consolidated financial statements in "Item 8. Financial Statements and Supplementary Data"  of this Annual Report on 
Form 10-K. 

2. 

GUARANTEES 

As the parent of Alliance Coal and the Intermediate Partnership, ARLP is a guarantor of the Credit Facility and the 
Senior Notes discussed in "Item 8. Financial Statements and Supplementary Data—Note 6 – Long-Term Debt" of this 
Annual  Report  on  Form  10-K.    In  addition  to  these  guarantees,  ARLP  has  provided  guarantees  on  surety  indemnity 
agreements  and  financially  guaranteed  certain  coal  supply  agreements.  The  duration  of  these  guarantees  varies.  The 
maximum undiscounted potential future payment obligation for our guarantees of certain coal supply agreements as of 
December 31, 2023 is approximately $75.1 million.  These guarantees provide for compensation to customers based on 
additional cost to the customer to replace any contracted tons that our subsidiaries fail to deliver.  We do not expect to 
make any payments under these guarantees.    

3. 

CASH DISTRIBUTIONS RECEIVED 

We  received  distributions  of  $364.6  million,  $196.3 million  and  $52.2  million  from  our  consolidated  subsidiaries 

during the years ended December 31, 2023, 2022, and 2021, respectively.

CHANGES IN AND DISAGREEMENTS WITH ACCOUNTANT ON ACCOUNTING AND 
FINANCIAL DISCLOSURE 

None. 

ITEM 9A. 

CONTROLS AND PROCEDURES 

Disclosure Controls and Procedures.  We maintain controls and procedures designed to provide reasonable assurance 
that  information  required  to  be  disclosed  in  the  reports  we  file  with  the  SEC  is  recorded,  processed,  summarized  and 
reported within the time periods specified in the rules and forms of the SEC and that such information is accumulated and 
communicated to our management, including the CEO and CFO, as appropriate, to allow for timely decisions regarding 
required disclosures.  As required by Rule 13a-15(b) of the Exchange Act, we have evaluated, under the supervision and 
with the participation of our management, including the CEO and CFO, the effectiveness of the design and operation of 
our  disclosure  controls  and  procedures  (as  defined  in  Rule 13a-15(e) or  Rule 15d-15(e) of  the  Exchange  Act)  as  of 
December 31,  2023.    Based  on  this  evaluation,  the  CEO  and  CFO  concluded  that  these  controls  and  procedures  are 
effective as of December 31, 2023. 

Our management, including the CEO and CFO, does not expect that our disclosure controls or our internal controls 
over financial reporting will prevent all errors and all fraud.  A control system, no matter how well conceived and operated, 
can provide only reasonable, not absolute, assurance that the objectives of the control system are met.  Further, the design 
of a control system must reflect the fact that there are resource constraints, and the benefits of controls must be considered 
relative to their costs.  Because of the inherent limitations in all control systems, no evaluation of controls can provide 
absolute assurance that all control issues and instances of fraud, if any, within the ARLP Partnership have been detected.  
These inherent limitations include the realities that judgments in decision-making can be faulty, and that simple errors or 
mistakes can occur.  Additionally, controls can be circumvented by the individual acts of some persons, by collusion of 
two or more people, or by management override of the control.  The design of any system of controls also is based, in part, 
upon certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed 
in achieving its stated goals under all potential future conditions.  Over time, controls may become inadequate because of 
changes in conditions, or the degree of compliance with the policies or procedures may deteriorate.  Because of the inherent 
limitations in a cost-effective control system, misstatements due to error or fraud may occur and not be detected.  We 
monitor our disclosure controls and internal controls and make modifications as necessary; our intent in this regard is that 
the disclosure controls and the internal controls will be maintained as systems change and conditions warrant. 

Management's Annual Report on Internal Control over Financial Reporting.  Management of the ARLP Partnership 
is responsible for establishing and maintaining effective internal control over financial reporting as defined in Rules 13a-
15(f) under the Exchange Act.  The ARLP Partnership's internal control over financial reporting is designed to provide 
reasonable assurance to our management and Board of Directors of our general partner regarding the preparation and fair 
presentation of published financial statements.  Our controls are designed to provide reasonable assurance that the ARLP 
Partnership's assets are protected from unauthorized use and that transactions are executed in accordance with established 
authorizations and properly recorded.  The internal controls are supported by written policies and are complemented by a 
staff of competent business process owners and an internal auditor supported by competent and qualified external resources 
used to assist in testing the operating effectiveness of the ARLP Partnership's internal control over financial reporting.  
Management concluded that the design and operations of our internal controls over financial reporting at December 31, 
2023 are effective and provide reasonable assurance the books and records accurately reflect the transactions of the ARLP 
Partnership. 

Because of inherent limitations, internal control over financial reporting may not prevent or detect misstatements.  
Therefore, even those systems determined to be effective can provide only reasonable assurance with respect to financial 
statement preparation and presentation. 

Management assessed the effectiveness of our internal control over financial reporting as of December 31, 2023.  In 
making this assessment, management used the criteria set forth by COSO in Internal Control—Integrated Framework 
(2013).  Based on its assessment, management concluded that, as of December 31, 2023, the ARLP Partnership's internal 
control over financial reporting was effective based on those criteria, and management believes that we have no material 
internal control weaknesses in our financial reporting process.

Grant Thornton LLP, an independent registered public accounting firm, has made an independent assessment of the 
effectiveness  of  our  internal control  over  financial  reporting  as  of  December 31,  2023,  as  stated  in  their  report  that is 
included herein. 

Changes in Internal Controls Over Financial Reporting.  There have not been any changes in our internal controls 
over financial reporting (as defined in Rule 13a-15(f) or Rule 15d-15(f) of the Exchange Act) in the three months ended 
December 31,  2023  that  has materially  affected,  or  is  reasonably  likely  to  materially  affect,  our  internal  controls  over 
financial reporting.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM 

Board of Directors of Alliance Resource Management GP, LLC 
and Unitholders of Alliance Resource Partners, L.P. 

Opinion on internal control over financial reporting  
We  have  audited  the  internal control over  financial reporting  of  Alliance  Resource  Partners,  L.P.  (a  Delaware  limited 
partnership)  and  subsidiaries  (the  “Partnership”)  as  of  December  31,  2023,  based  on  criteria  established  in  the  2013 
Internal  Control—Integrated  Framework  issued  by  the  Committee  of  Sponsoring  Organizations  of  the  Treadway 
Commission (“COSO”). In our opinion, the Partnership maintained, in all material respects, effective internal control over 
financial  reporting  as  of  December  31,  2023,  based  on  criteria  established  in  the  2013  Internal  Control—Integrated 
Framework issued by COSO. 

We  also  have  audited,  in  accordance  with  the  standards  of  the  Public  Company  Accounting  Oversight  Board  (United 
States) (“PCAOB”), the consolidated financial statements of the Partnership as of and for the year ended December 31, 
2023, and our report dated February 23, 2024 expressed an unqualified opinion on those financial statements. 

Basis for opinion 
The Partnership’s management is responsible for maintaining effective internal control over financial reporting and for its 
assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management’s 
Annual  Report  on  Internal  Control  over  Financial  Reporting.  Our  responsibility  is  to  express  an  opinion  on  the 
Partnership’s internal control over financial reporting based on our audit. We are a public accounting firm registered with 
the PCAOB and are required to be independent with respect to the Partnership in accordance with the U.S. federal securities 
laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.  

We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform 
the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained 
in  all  material  respects.  Our  audit  included  obtaining  an  understanding  of  internal  control  over  financial  reporting, 
assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal 
control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. 
We believe that our audit provides a reasonable basis for our opinion. 

Definition and limitations of internal control over financial reporting  
A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the 
reliability  of  financial  reporting  and  the  preparation  of  financial  statements  for  external  purposes  in  accordance  with 
generally accepted accounting principles. A company’s internal control over financial reporting includes those policies 
and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the 
transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded 
as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, 
and that receipts and expenditures of the company are being made only in accordance with authorizations of management 
and  directors  of  the  company;  and  (3)  provide  reasonable  assurance  regarding  prevention  or  timely  detection  of 
unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial 
statements. 

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, 
projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate 
because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Board of Directors 

Mr. Craft, who has been President and CEO and a member of the Board of Directors since ARLP's inception, assumed 
the Chairman role effective January 1, 2019.  We believe this leadership structure of the Board of Directors is appropriate 
for the Partnership given Mr. Craft's extensive knowledge of our industries, significant ownership position, and proven 
leadership of the Partnership. 

The Board of Directors generally administers its risk oversight function through the board as a whole.  The Chairman, 
President  and  CEO,  who  reports  to  the  Board  of  Directors,  and  the  other  executives  named  above,  who  report  to  the 
Chairman, President and CEO or, in the case of Mrs. Cordle, the CFO, have day-to-day risk management responsibilities.  
At the Board of Directors' request, each of these executives attends the meetings of the Board of Directors, where the 
Board  of  Directors  routinely  receives  reports  on  our  financial  results,  the  status  of  our  operations  and  our  safety 
performance,  and  other  aspects  of  the  implementation  of  our  business  strategy,  with  ample  opportunity  for  specific 
inquiries of management.  In addition, management provides periodic reports of the Partnership's financial and operational 
performance to each member of the Board of Directors.  The Audit Committee provides additional risk oversight through 
its quarterly meetings, where it receives a report from the Partnership's internal auditor, who reports directly to the Audit 
Committee,  and  reviews  the  Partnership's  contingencies,  significant  transactions  and  subsequent  events,  among  other 
matters, with management and our independent auditors. 

The Board of Directors has selected as director nominees individuals with experience, skills and qualifications relevant 
to the business of the Partnership, such as experience in energy or related industries or with financial markets, expertise in 
mining, engineering or finance, and a history of service in senior leadership positions.  The Board of Directors has not 
established a formal process for identifying director nominees, nor does it have a formal policy regarding the consideration 
of diversity in identifying director nominees, but has endeavored to assemble a talented group of individuals with the 
qualities and attributes required to provide effective oversight of the Partnership. 

Audit Committee 

The Audit Committee comprises all four non-employee members of the Board of Directors (Messrs. Carter, Druten, 
Robinson, and Torrence).  After reviewing the qualifications of the current members of the Audit Committee, and any 
relationships they may have with us that might affect their independence, the Board of Directors has determined that all 
current Audit Committee members are "independent" as that concept is defined in Section 10A of the Exchange Act, all 
current Audit Committee members are "independent" as that concept is defined in the applicable rules of NASDAQ Stock 
Market,  LLC,  all  current  Audit  Committee  members  are  financially  literate,  and  Mr. Torrence  qualifies  as  an  "audit 
committee financial expert" under the applicable rules promulgated pursuant to the Exchange Act.

Report of the Audit Committee 

The Audit Committee oversees our financial reporting process on behalf of the Board of Directors.  Management has 
primary responsibility for the financial statements and the reporting process including the systems of internal controls.  
The Audit Committee has responsibility for the appointment, compensation and oversight of the work of our independent 
registered public accounting firm and assists the Board of Directors by conducting its own review of our: 

• 

• 

• 

• 

filings with the SEC pursuant to the Securities Act and the Exchange Act (i.e., Forms 10-K, 10-Q, and 8-K); 

press releases and other communications by us to the public concerning earnings, financial condition and results 
of operations, including changes in distribution policies or practices affecting the holders of our units, if such 
review is not undertaken by the Board of Directors; 

systems of internal controls regarding finance and accounting that management and the Board of Directors have 
established; and 

auditing, accounting and financial reporting processes generally. 

In fulfilling its oversight and other responsibilities, the Audit Committee met eight times during 2023.  The Audit 
Committee's activities included, but were not limited to: (a) selecting the independent registered public accounting firm, 
(b) meeting periodically in executive session with the independent registered public accounting firm, (c) reviewing the 
Quarterly Reports on Form 10-Q for the three months ended March 31, June 30, and September 30, 2023, (d) performing 
a self-assessment of the committee, (e) reviewing the Audit Committee charter, and (f) reviewing the overall scope, plans 
and findings of our internal auditor.  Based on the results of the annual self-assessment, the Audit Committee believes that 
it satisfied the requirements of its charter.  A copy of the Audit Committee charter is publicly available on our website 
under "Investor Relations" at www.arlp.com and is available in print without charge to any unitholder who requests it.  
Such  requests  should  be  directed  to  Investor  Relations  at  (918)  295-7673.    The  Audit  Committee  also  reviewed  and 
discussed with management and the independent registered public accounting firm this Annual Report on Form 10-K, 
including the audited financial statements. 

Our independent registered public accounting firm, Grant Thornton, is responsible for expressing an opinion on the 
conformity  of  the  audited  financial  statements  with  GAAP.    The  Audit  Committee  reviewed  with  Grant  Thornton  its 
judgment as to the quality, not just the acceptability, of our accounting principles and such other matters as are required to 
be discussed with the Audit Committee pursuant to the applicable requirements of the PCAOB and the SEC. 

The  Audit  Committee  received  written  disclosures  and  the  letter  from  Grant  Thornton  required  by  applicable 
requirements of the PCAOB Rule 3526, "Communication with Audit Committees Concerning Independence," and has 
discussed with Grant Thornton its independence from management and the ARLP Partnership. 

Based on the reviews and discussions referred to above, the Audit Committee recommended to the Board of Directors 
that the audited financial statements be included in the Annual Report on Form 10-K for the year ended December 31, 
2023 for filing with the SEC. 

Members of the Audit Committee: 

Wilson M. Torrence, Chairman 
Nick Carter 
Robert J. Druten 
John H. Robinson 

Code of Ethics 

We have adopted a code of ethics with which the  Chairman, President and CEO and the senior financial officers 
(including the principal financial officer and the principal accounting officer) are expected to comply.  The code of ethics 
is publicly available on our website under "Investor Relations" at www.arlp.com and is available in print without charge 
to  any  unitholder  who  requests  it.    Such  requests  should  be  directed  to  Investor  Relations  at  (918)  295-7673.    If  any 

163 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
substantive amendments are made to the code of ethics or if there is a grant of a waiver, including any implicit waiver, 
from a provision of the code to the President and CEO, Chief Financial Officer, or Chief Accounting Officer, we will 
disclose  the  nature  of  such  amendment  or  waiver  on  our  website  or  in  a  report  on  Form 8-K.    There  were  no  such 
amendments or waivers during the year ended December 31, 2023. 

Communications with the Board 

Unitholders or other interested parties can contact any director or committee of the Board of Directors by writing to 
them  c/o  Senior  Vice  President,  General  Counsel  and  Secretary,  P.O. Box  22027,  Tulsa,  Oklahoma  74121-2027.  
Comments or complaints relating to our accounting, internal accounting controls or auditing matters will also be referred 
to members of the Audit Committee.  The Audit Committee has procedures for (a) receipt, retention and treatment of 
complaints received by us regarding accounting, internal accounting controls, or auditing matters and (b) the confidential, 
anonymous submission by our employees of concerns regarding questionable accounting or auditing matters. 

Section 16(a) Beneficial Ownership Reporting Compliance 

Section 16(a) of the Exchange Act, as amended, requires directors, executive officers and persons who beneficially 
own more than ten percent of a registered class of our equity securities to file with the SEC initial reports of ownership 
and reports or changes in ownership of such equity securities. Based on a review of the copies of the forms furnished to 
us  and  written  representations  from  certain  reporting  persons,  we  believe  that  during  2023  none  of  our  directors  or 
executive officers or persons who beneficially owned more than ten percent of a registered class of our equity securities 
were delinquent with respect to any of the filing requirements under Section 16(a), with the following exception: a Form 
3/A was filed on November 7, 2023 for Ms. Kathleen Mowry, who beneficially owns more than ten percent of our common 
units, to correct her reported beneficial ownership in her initial Form 3 filed on June 5, 2018. 

Reimbursement of Expenses of our General Partner and its Affiliates 

Our general partner does not receive any management fee or other compensation in connection with its management 
of us.  Our general partner is reimbursed by us for all expenses incurred on our behalf.  Please see "Item 13. Certain 
Relationships and Related Transactions, and Director Independence—Administrative Services." 

ITEM 11. 

EXECUTIVE COMPENSATION 

Compensation Discussion and Analysis 

Introduction 

The Compensation Committee oversees the compensation of our general partner's executive officers, including the 
Named Executive Officers, each of whom is named in the Summary Compensation Table.  Our Named Executive Officers 
are employees of our operating subsidiary, Alliance Coal.  We do not currently, nor did we during the 2023 calendar year, 
maintain employment agreements with any of our Named Executive Officers. 

Compensation Objectives and Philosophy 

The  compensation  of  our  Named  Executive  Officers  is  designed  to  achieve  three  key  objectives:  (i) provide  a 
competitive compensation opportunity to allow us to recruit and retain key management talent, (ii) align executive officers' 
interests with unitholder interests and (iii) motivate and reward the executive officers for creating sustainable, capital-
efficient growth in available cash to maximize unitholder returns.  In making decisions regarding executive compensation, 
the Compensation Committee reviews current compensation levels of other companies in the coal industry and other peers, 
considers  the  Chairman,  President  and  CEO's  assessment  of  each  of  the  other  executives,  and  uses  its  discretion  to 
determine  an  appropriate  total  compensation  package  of  base  salary  and  short-term  and  long-term  incentives.    The 
Compensation Committee intends for each executive officer's total compensation to be competitive in the marketplace and 
to effectively motivate the officer.  Based on its review of our overall executive compensation program, the Compensation 
Committee believes the program is appropriately applied to our general partner's executive officers and is necessary to 
attract and retain the executive officers who are essential to our continued development and success, to compensate those 
executive  officers  for  their  contributions  and  to  enhance  unitholder  value.    Moreover,  the  Compensation  Committee 
believes the total compensation opportunities provided to our general partner's executive officers create alignment with 

164 

 
 
 
 
  
 
 
 
 
 
 
 
our long-term interests and those of our unitholders.  As a result, we do not maintain unit ownership requirements for our 
Named Executive Officers. 

Setting Executive Compensation 

Role of the Compensation Committee 

The  Compensation  Committee  discharges  the  Board  of  Directors'  responsibilities  relating  to  our  general  partner's 
executive  compensation  program.    The  Compensation  Committee  oversees  our  compensation  and  benefit  plans  and 
policies,  administers  our  incentive  bonus  and  equity  participation  plans,  and  reviews  and  approves  annually  all 
compensation decisions relating to our Named Executive Officers.  The Compensation Committee is empowered by the 
Board of Directors and by the Compensation Committee's charter to make all decisions regarding compensation for our 
Named Executive Officers without ratification or other action by the Board of Directors.  The Compensation Committee 
has the authority to secure services for executive compensation matters, legal advice, or other expert services, both from 
within and outside the company.  While the Compensation Committee is empowered to delegate all or a portion of its 
duties to a subcommittee, it has not done so. 

The Compensation Committee comprises all of our directors who have been determined to be "independent" by the 
Board  of  Directors  in  accordance  with  applicable  NASDAQ  Stock  Market,  LLC  and  SEC  regulations,  presently 
Messrs. Robinson, Carter, Druten and Torrence. 

Role of Executive Officers 

Each  year,  the  Chairman,  President  and  CEO  submits  recommendations  to  the  Compensation  Committee  for 
adjustments  to  the  salary,  bonuses  and  long-term  equity  incentive  awards  payable  to  our  Named  Executive  Officers, 
excluding himself.  The Chairman, President and CEO bases his recommendations on his assessment of each executive's 
performance, experience, demonstrated leadership, job knowledge and management skills.  The Compensation Committee 
considers  the  recommendations  of  the  Chairman,  President  and  CEO  as  one  factor  in making  compensation  decisions 
regarding our Named Executive Officers.  Historically, and in 2023, the Compensation Committee and the Chairman, 
President  and  CEO  have been  substantially  aligned  on  decisions  regarding  the  compensation  of  the  Named  Executive 
Officers.    As  executive  officers  are  promoted  or  hired  during  the  year,  the  Chairman,  President  and  CEO  makes 
compensation recommendations to the Compensation Committee and works closely with the Compensation Committee to 
ensure that all compensation arrangements for executive officers are consistent with our compensation philosophy and are 
approved by the Compensation Committee.  At the direction of the Compensation Committee, the Chairman, President 
and  CEO  and  the  Senior  Vice  President,  General  Counsel and  Secretary  attend  certain meetings  of  the  Compensation 
Committee. 

Use of Peer Group Comparisons 

The Compensation Committee believes that it is important to review and compare our performance with that of peer 
companies in the coal industry and reviews the composition of the peer group annually.  The peer group for 2023 (which 
was  the  same  peer  group  applicable  to  the  2022  calendar  year)  included  Alpha  Metallurgical  Resources,  Inc.,  Arch 
Resources, Inc., Consol Energy, Inc., Natural Resource Partners L.P., Peabody Energy Corporation, and Warrior Met Coal, 
Inc.  In assessing the competitiveness of our executive compensation program for 2023, the Compensation Committee, 
with  the  assistance  of  the  Chairman,  President  and  CEO,  collected  and  analyzed  peer  group  proxy  information  and 
developed a comparative analysis of base salaries, short-term incentives, total cash compensation, long-term incentives 
and total compensation.  The Compensation Committee uses the peer group data as a point of reference for comparative 
purposes, but it is not the determinative factor for the compensation of our Named Executive Officers.  The Compensation 
Committee exercises discretion in determining the nature and extent of the use of comparative pay data. 

Consideration of Equity Ownership and CEO Compensation 

Mr. Craft, the Chairman, President and CEO, is evaluated and treated differently with respect to compensation than 
our other Named Executive Officers.  Mr. Craft and related entities own significant equity positions in ARLP and Mr. 
Craft indirectly owns our general partner.  Because of these ownership positions, the interests of Mr. Craft are directly 
aligned with those of our unitholders.  Mr. Craft has not received an increase in base salary since 2002, has not received a 
bonus under our STIP since 2005 and did not receive any grants of LTIP awards from 2005 through 2015.  On January 

165 

 
 
 
 
 
 
 
 
 
 
22, 2016, the Compensation Committee approved an LTIP award for Mr. Craft that vested on January 1, 2019.  Mr. Craft 
has not received any subsequent LTIP awards.  Beginning in February 2016, at Mr. Craft's request, his annual base salary 
was reduced to $1. 

Compensation Components 

Overview 

The principal components of compensation for our Named Executive Officers (other than Mr. Craft) include: 

• 

• 

• 

base salary; 

annual cash incentive bonus awards under the STIP; and 

awards of restricted units under the LTIP, including DERs. 

The relative amount of each component is not based on any formula, but rather is based on the recommendation of 
the Chairman, President and CEO, subject to the discretion of the Compensation Committee to make any modifications it 
deems appropriate. 

All executive officers, including the Named Executive Officers, are entitled to customary benefits available to our 
employees generally, including group medical, dental, and life insurance and participation in our PSSP.  Our PSSP is a 
defined contribution plan and includes an employer matching contribution of 75% on the first 3% of eligible compensation 
contributed by the employee, an employer non-matching contribution of 0.75% of eligible compensation, and an employer 
supplemental  contribution  of 5%  of  eligible  compensation.    The  PSSP  provides  an  additional  means  of  attracting  and 
retaining qualified employees by providing tax-advantaged opportunities for employees to save for retirement. Each of 
our Named Executive Officers (including Mr. Craft) also received supplemental retirement benefits through the SERP in 
2023, which are described in more detail below.   

Base Salary 

When reviewing base salaries, the Compensation Committee's policy is to consider the individual's experience, tenure 
and performance, the individual's level of responsibility, the position's complexity and its importance to us in relation to 
other executive positions, our financial performance, and competitive pay practices.  The Compensation Committee also 
considers  comparative  compensation  data  of  companies  in  our  peer  group  and  the  recommendation  of  the  Chairman, 
President and CEO of our general partner.  Base salaries are reviewed annually to ensure continuing consistency with 
market levels, and adjustments to base salaries are made as needed to reflect movement in the competitive market as well 
as individual performance. None of our Named Executive Officers received an increase in salary during the 2023 year. 

Annual Cash Incentive Bonus Awards  

The STIP is designed to assist us in attracting, retaining and motivating qualified personnel by rewarding management, 
including our Named Executive Officers, and selected other salaried employees with cash awards for our achievement of 
an annual financial performance target.  The annual performance target is recommended by the Chairman, President and 
CEO  and  approved  by  the  Compensation  Committee,  typically  in  January of  each  year.    The  performance  measure  is 
subject to equitable adjustment in the sole discretion of the Compensation Committee to reflect the occurrence of any 
significant events during the year. 

The  performance  target  historically  has  been  EBITDA-based,  with  items  added  or  removed  from  the  EBITDA 
calculation to ensure that the performance target reflects the operating results of our core businesses.  (EBITDA is defined 
as net income of ARLP before net interest expense, income taxes, depreciation, depletion and amortization and net income 
attributable to noncontrolling interest.)  The aggregate cash available for awards under the STIP each year is dependent on 
our  actual financial  results  for  the  year  compared  to  the  annual  performance  target,  and  it  increases  in  relation  to our 
EBITDA,  as  adjusted,  exceeding  the  minimum  threshold.    Our  STIP  Guidelines  provide  that  achieving  the  minimum 
threshold is the minimum acceptable result for a performance pay-out to occur under the STIP, although the Compensation 
Committee may determine satisfactory results and adjust the size of the pay-out pool in its sole discretion.  In 2023, the 
Compensation Committee approved a minimum financial performance target of $756.2 million in EBITDA from current 

166 

 
 
 
 
 
 
 
 
 
 
 
 
 
operations, normalized by excluding any charges for unit-based and directors' compensation.  For 2023, we exceeded the 
minimum performance target.   

Individual  awards  to  our  Named  Executive  Officers  each  year  are  determined  by  the  Compensation  Committee.  
However, the Compensation Committee does not establish individual target payout amounts for the Named Executive 
Officers' STIP awards.  As it does when reviewing base salaries, in determining individual awards under the STIP, the 
Compensation  Committee  considers  its  assessment  of  the  individual's  performance,  our  financial  performance, 
comparative compensation data of companies in our peer group and the recommendation of the Chairman, President and 
CEO,  although  EBITDA-based  performance  targets  described  above  are  given  significant  weight.    The  compensation 
expense associated with STIP awards is recognized in the year earned, with the cash awards generally payable in the first 
quarter of the following calendar year.  Termination of employment of an executive officer for any reason prior to payment 
of a cash award will result in forfeiture of any right to the award, unless and to the extent waived by the Compensation 
Committee in its discretion. 

The performance measure for the STIP in 2024 will be based on adjusted EBITDA for current operations, excluding 
charges  for  unit-based  and  directors'  compensation.    As  discussed  above,  the  Compensation  Committee  may,  in  its 
discretion, make equitable adjustments to the performance criteria under the STIP and adjust the amount of the aggregate 
pay-out.  The Compensation Committee believes the STIP performance criteria for 2024 will be reasonably difficult to 
achieve and therefore support our key compensation objectives discussed above. 

The Compensation Committee maintains discretion to grant cash bonus awards outside of the STIP to address special 

situations.   

Equity Awards under the LTIP 

Equity compensation pursuant to the LTIP is a key component of our executive compensation program.  Our LTIP is 
sponsored by Alliance Coal.  Under the LTIP, grants may be made of either (a) restricted units, (b) options to purchase 
common units (although to date, no grants of options have been made) or (c) cash awards.  The Compensation Committee 
has the authority to determine the participants to whom restricted units are granted, the number of restricted units to be 
granted to each such participant, and the conditions under which the restricted units may become vested, including the 
duration of any vesting period.  Annual grant levels for designated participants (including our Named Executive Officers) 
are  recommended  by  our  general  partner's  Chairman,  President  and  CEO,  subject  to  review  and  approval  by  the 
Compensation  Committee.    Grant  levels  are  intended  to  support  the  objectives  of  the  comprehensive  compensation 
package  described  above.    The  LTIP  grants  provide  our  Named  Executive  Officers  with  the  opportunity  to  achieve  a 
meaningful ownership stake in the Partnership, thereby assuring that their interests are aligned with our success.  Even 
though Mr. Craft has not been granted an award under the LTIP since 2005, with the exception of one grant in 2016, the 
Compensation Committee believes Mr. Craft's interests are directly aligned with the interests of our unitholders as a result 
of his ownership positions.  There is no formula for determining the size of awards to any individual recipient and, as it 
does when reviewing base salaries and individual STIP payments, the Compensation Committee considers its assessment 
of the individual's performance, our financial performance, compensation levels at peer companies in the coal industry and 
the recommendation of the Chairman, President and CEO.  Amounts realized from prior grants, including amounts realized 
due to changes in the value of our common units, are not considered in setting grant levels or other compensation for our 
Named Executive Officers. 

Restricted Units.  Restricted units granted under the LTIP are "phantom" or notional units that upon vesting entitle 
the participant to receive an ARLP common unit.  Restricted units granted under the LTIP vest at the end of a stated period 
from  the  grant  date,  provided  we  achieve  an  aggregate  performance  target  for  that  period.    However,  if  a  grantee's 
employment  is  terminated  for  any  reason  prior  to  the  vesting  of  any  restricted  units,  those  restricted  units  will  be 
automatically forfeited, unless the Compensation Committee, in its sole discretion, determines otherwise.  The number of 
units distributed upon satisfaction of the applicable vesting requirements is reduced to cover the income tax withholding 
requirement for each individual participant based on the fair market value of the common units as of the date of distribution.  
At the Compensation Committee's discretion, grants of restricted units under the LTIP may include the contingent right to 
receive  quarterly distributions  in  an  amount  equal  to  the  cash  distributions  we  make  to  unitholders  during  the vesting 
period.  DERs are payable, in the discretion of the Compensation Committee, either in cash or in the form of additional 
Restricted Units credited to a book-keeping account subject to the same vesting restrictions as the tandem award. 

167 

 
 
 
 
 
 
 
The performance target applicable to restricted unit awards under the LTIP is based on a normalized EBITDA measure 
and requires achieving an aggregate performance level for the vesting period.  We typically issue grants under the LTIP 
at the beginning of each year, with the exceptions of new employees who begin employment with us at some other time 
and  job  promotions  that  may  occur  at  some  other  time.    The  compensation  expense  associated  with  LTIP  grants  is 
recognized over the vesting period in accordance with FASB ASC 718, Compensation — Stock Compensation. 

Our  general  partner's  policy  is  to  grant  restricted  units  pursuant  to  the  LTIP  to  serve  as  a  means  of  incentive 
compensation for performance.  Therefore, no consideration will be payable by the LTIP participants upon receipt of the 
common units.  Common units to be delivered upon the vesting of restricted units may be common units we already own, 
common units we acquire in the open market or from any other person, newly issued common units, or any combination 
of the foregoing.  If we issue new common units upon payment of the restricted units instead of purchasing them, the total 
number of common units outstanding will increase. 

The LTIP provides the Compensation Committee with the discretion to determine the conditions for vesting (as well 
as all other terms and conditions) associated with any award under the plan, and to amend any of those conditions so long 
as an amendment does not materially reduce the benefit to the participant.  The Compensation Committee believes the 
performance-related vesting conditions of all outstanding awards under the LTIP will be reasonably difficult to satisfy and 
therefore support our key compensation objectives discussed above.     

Grants for 2023 under the LTIP, made January 27, 2023, will cliff vest on January 1, 2026, provided we achieve a 
target level of aggregate EBITDA for current operations, excluding any charges for unit-based and directors' compensation, 
for the period January 1, 2023 through December 31, 2025.  Regardless of achieving the EBITDA target, the 2023 grants 
have a minimum value guarantee of either $10.27 or $15.41 per unit.  Grants for 2024 under the LTIP, made January 24, 
2024, will cliff vest on January 1, 2027, provided we achieve a target level of aggregate EBITDA for current operations, 
excluding any charges for unit-based and directors' compensation, for the period January 1, 2024 through December 31, 
2026.  Regardless of achieving the EBITDA target, the 2024 grants have a minimum value guarantee of either $10.63 or 
$15.95 per unit.  The LTIP provides the Compensation Committee with the discretion to determine the conditions for 
vesting (as well as all other terms and conditions) associated with any award under the plan, and to amend any of those 
conditions  so  long  as  an  amendment  does  not  materially  reduce  the  benefit  to  the  participant.    The  Compensation 
Committee  believes  the  performance-related  vesting  conditions  of  all  outstanding  awards  under  the  LTIP  will  be 
reasonably difficult to satisfy and therefore support our key compensation objectives discussed above. 

Unit Options.  We have not made any grants of unit options. The Compensation Committee, in the future, may decide 

to make unit option grants to employees and directors on terms determined by the Compensation Committee. 

Grant Timing.  The Compensation Committee does not time, nor has the Compensation Committee in the past timed, 
the grant of LTIP awards in coordination with the release of material non-public information.  Instead, LTIP awards are 
granted  only  at  the  time  or  times  dictated  by  our  normal  compensation  process  as  developed  by  the  Compensation 
Committee. 

Effect of a Change in Control.  Upon a "change in control" as defined in the LTIP, all awards outstanding under the 
LTIP will automatically vest and become payable or exercisable, as the case may be, in full.  Please see "Item 11. Executive 
Compensation—Potential Payments Upon a Termination or Change of Control." 

Amendments  and  Termination.    The  Board  of  Directors  or  the  Compensation  Committee  may,  in  its  discretion, 
terminate the LTIP at any time with respect to any common units for which a grant has not previously been made.  Except 
as required by the rules of the exchange on which the common units may be listed at that time, the Board of Directors or 
the Compensation Committee may alter or amend the LTIP in any manner from time to time; provided, however, that no 
change in any outstanding grant may be made that would materially impair the rights of the participant without the consent 
of the affected participant.  In addition, the Board of Directors or the Compensation Committee may, in its discretion, 
establish such additional compensation and incentive arrangements as it deems appropriate to motivate and reward our 
employees. 

Supplemental Executive Retirement Plan 

The SERP is sponsored by Alliance Coal.  Participation in the SERP aligns the interest of each participant with the 
interests of our unitholders because all allocations made to participants under the SERP are made in the form of notional 
common units of ARLP, defined in the SERP as "phantom units."  The Compensation Committee approves the SERP 

168 

 
 
 
 
 
 
 
 
 
participants and their percentage allocations, and could amend or terminate the SERP at any time.  All of our Named 
Executive Officers currently participate in the SERP. 

On December 14, 2023 the Compensation Committee approved termination of the SERP, and authorized distribution 
of accounts to participants on December 15, 2024 or as soon thereafter as practical.  Account settlements must be delayed 
at least one year according to termination rules governing the SERP. The accounts will continue to accrue benefits in 
accordance with plan terms until distributed. 

Under  the  terms  of  the  SERP,  a participant  was  entitled  to  receive  on  December 31  of each  year  an  allocation of 
phantom units having a fair market value equal to his or her percentage allocation multiplied by the sum of the participant's 
base salary and cash bonus received that year, then reduced by any supplemental contribution that was made to our defined 
contribution PSSP for the participant that year.  A participant's cumulative notional phantom unit account balance earns 
the equivalent of common unit distributions, which are added to the notional account balance in the form of additional 
phantom  units.    All  amounts  granted  under  the  SERP  vest  immediately  and  would  be  paid  out  upon  the  participant's 
termination  from  employment  in  ARLP  common  units  equal  to  the  number  of  phantom  units  then  credited  to  the 
participant's account, less the number of units required to satisfy our tax withholding obligations.  A participant in the 
SERP is not entitled to an allocation for the year in which his termination from employment occurs, except as described 
below. 

A participant in the SERP is entitled to receive an allocation under the SERP for the year in which his employment is 

terminated only if such termination results from one of the following events: 

(1)  the participant's employment is terminated other than for "cause"; 

(2)  the participant terminates employment for "good reason"; 

(3)  a change of control of us or our general partner occurs and, as a result, the participant's employment is terminated 

(whether voluntary or involuntary); 

(4)  death of the participant; 

(5)  the participant attains (or has attained)  retirement age of 65 years; or 

(6)  the participant incurs a total and permanent disability, which shall be deemed to occur if the participant is eligible 

to receive benefits under the terms of the long-term disability program we maintain. 

This  allocation  for  the  year  in  which  a  participant's  termination  occurred  shall  equal  the  participant's  eligible 
compensation for such year (including any severance amount, if applicable) multiplied by his percentage allocation under 
the SERP, reduced by any supplemental contribution that was made to our defined contribution PSSP for the participant 
that year. 

Other Compensation-Related Matters 

Securities Trading Policy; Prohibitions on Hedging and Trading in Derivatives 

To ensure alignment of the interests of our unitholders with our directors and all officers, including Named Executive 
Officers, the general partner's Securities Trading Policy prohibits any employee, officer, or director of the Partnership or 
any of its subsidiaries from engaging in trading involving (1) options or other derivative securities relating to ARLP units; 
(2) debt securities of ARLP or its affiliates; (3) hedging transactions involving ARLP securities; or (4) purchases of ARLP 
units on margin. 

Tax Deductibility of Compensation 

The deduction limitations imposed under Section 162(m) of the Internal Revenue Code do not apply to compensation 
paid to our Named Executive Officers because we are a limited partnership and not a "corporation" within the meaning of 
Section 162(m). 

169 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Perquisites and Personal Benefits 

The Partnership provides a limited amount of perquisites and personal benefits to the Named Executive Officers in 
keeping  with  the  Compensation  Committee's  objectives  to  provide  competitive  compensation  to  motivate  and  reward 
executive  officers  for  creating  sustainable,  capital-efficient  growth  in  available  cash.    These  perquisites  and  personal 
benefits  typically  include  amounts  for  items  such  as  tax  preparation fees  and  annual physical  medical  exams,  and  are 
reviewed annually by the Compensation Committee. 

Clawback Policy 

We maintain the Alliance Resource Partners, L.P. Incentive-Based Compensation Recoupment Policy (the "Clawback 
Policy"),  which  is  administered  by  the  Compensation  Committee.  The  Clawback  Policy  authorizes  the  Compensation 
Committee to recoup incentive compensation in the event of a restatement of financial statements. A copy of the Clawback 
Policy is filed as Exhibit 97.1 to this Annual Report on Form 10-K. 

Compensation Committee Report

(1)  Mr.  Cantrell  retired  from  his  position  as  Senior  Vice  President  and  CFO  on  March  31,  2023.  Mr.  Marshall  was 

appointed Senior Vice President and CFO effective April 1, 2023. 

(2)  Amounts represent the salary earned by each Named Executive Officer for the respective year.  The amounts for Mr. 

Cantrell include $23,385 paid in 2023 for unused vacation upon his retirement on March 31, 2023. 

(3)  The amount for Mr. Marshall represents the second payment of the 2020 service-based vesting LTIP awards which 
was paid in cash in February 2023. The amounts for Messrs. Cantrell, Davis and Wynne represent the first and second 
payments of the 2020 service-based vesting LTIP awards which were paid in cash in February 2022 and February 
2023, respectively, as well as a cash bonus paid in 2023 to Mr. Cantrell.  The amounts for Mr. Tholen represent the 
payments of his 2019 and 2020 service-based vesting LTIP awards which were paid in cash in February 2022 and 
2023, respectively, and the last installment of his signing bonus paid in 2021. 

(4)  The Unit Awards represent the aggregate grant date fair value of restricted units granted pursuant to FASB ASC 718, 
using the same assumptions as used for financial reporting purposes and which are more fully described in "Item 8.  
Financial  Statements  and  Supplementary  Data—Note  16  –  Common  Unit-Based  Compensation  Plans,"  to  each 
Named Executive Officer under the LTIP in the respective year.  Please see "Item 11. Compensation Discussion and 
Analysis—Compensation Program Components—Equity Awards under the LTIP" for a description of the terms of 
the awards. 

(5)  Amounts represent the STIP bonus earned for the respective year. STIP payments typically are made in the first quarter

(1)  In accordance with the provisions of the SERP, a participant's cumulative notional phantom unit account balance earns 
the equivalent of common unit distributions when we pay a distribution to our common unitholders, which is added 
to the account balance in the form of phantom units. 

(2)  These  contributions  are  made  in  accordance  with  the  SERP  plan  document  that  has  been  approved  by  the 
Compensation  Committee.    Therefore,  these  contributions  are  not  separately  approved  by  the  Compensation 
Committee. 

(3)  Awards under the STIP are subject to our achieving an annual financial performance target each year.  However, 
determination  of  individual  awards  under  the  STIP  is  based  on  an  assessment  of  the  Named  Executive  Officer's 
performance, comparative compensation data of companies in our peer group and recommendation of the Chairman, 
President and CEO.  The STIP does not specify any threshold or maximum payout amounts.  Please see "Item 11. 
Compensation Discussion and Analysis—Compensation Components—Annual Cash Incentive Bonus Awards" for 
additional information regarding the STIP awards. 

(4)  These amounts represent awards pursuant to our STIP.  On January 27, 2023, the Compensation Committee set the 
EBITDA target amount for use in determining the total plan payout for 2023.  The discretionary payout allocations to 
all participating employees is determined after the year is completed.  Please see "Item 11. Compensation Discussion 
and  Analysis—Compensation  Components—Annual  Cash  Incentive  Bonus  Awards"  for  additional  information 
regarding the STIP awards.

(5)  Grants of restricted units under our LTIP are generally not subject to minimum thresholds, targets or maximum payout 
conditions.  However, the vesting of these grants is subject to the satisfaction of certain performance criteria.  The 
grants  include  a  minimum  value  guarantee.    Please  see  "Item  11.  Compensation  Discussion  and  Analysis—
Compensation Components—Equity Awards under the LTIP."  

(6)  These awards are grants of restricted units pursuant to our LTIP.  The grants include a minimum value guarantee.  Mr. 
Cantrell did not receive an LTIP award in 2023 as his retirement in March 2023 was prior to the vesting of these 
grants.  Please see "Item 11. Compensation Discussion and Analysis—Compensation Components—Equity Awards 
under the LTIP."  

(7)  These awards are phantom units added to each Named Executive Officer's SERP notional account balance.  Please 
see  "Item  11.    Compensation  Discussion  and  Analysis—Compensation  Components—Supplemental  Executive 
Retirement Plan."  

(8)  We calculated the fair value of LTIP awards granted on February 15, 2023 to our Named Executive Officers using a 
value of $21.54 per unit, the closing unit price on the grant date.  We calculated the fair value of SERP phantom unit 
awards using the market closing price on the date the phantom unit award was granted.  Phantom units granted under 
the SERP vest on the date granted. 

Narrative Disclosure Relating to the Summary Compensation Table and Grants of Plan-Based Awards Table 

Annual Cash Incentive Bonus Awards 

Under the STIP, our Named Executive Officers are eligible for cash awards for our achieving an annual financial 
performance target.  The annual performance target is recommended by the Chairman, President and CEO of our general 
partner  and  approved  by  the  Compensation  Committee,  typically  in  January of  each  year.    The  performance  target 
historically  has  been  EBITDA-based,  with  items  added  or  removed  from  the  EBITDA  calculation  to  ensure  that  the 
performance  target  reflects  the  pure  operating  results  of  our  core  business.    (EBITDA  is  calculated  as  net  income 
attributable  to  ARLP  before  net  interest  expense,  income  taxes  and  depreciation,  depletion  and  amortization.)    The 
aggregate cash available for awards under the STIP each year is dependent on our actual financial results for the year 
compared  to  the  annual  performance  target.  The  cash  available  generally  increases  in  relationship  to our  EBITDA,  as 
adjusted,  exceeding  the  minimum  financial  performance  target  and  is  subject  to  adjustment  by  the  Compensation 
Committee in its discretion.  The Compensation Committee maintains discretion to grant cash bonus awards outside of the 
STIP  to  address  special  situations.    Please  see  "Item  11.  Compensation  Discussion  and  Analysis—Compensation 
Components—Annual Cash Incentive Bonus Awards." 

Long-Term Incentive Plan 

Under the LTIP, grants may be made of either (a) restricted units, (b) options to purchase common units, although to 
date, no grants of options have been made, and (c) cash awards.  Annual grant levels for designated participants (including 
our Named Executive Officers) are recommended by our general partner's Chairman, President and CEO, subject to the 
review and approval of the Compensation Committee.  Restricted units granted under the LTIP are "phantom" or notional 
units that upon vesting entitle the participant to receive an ARLP unit.  Restricted units granted under the LTIP vest at the 
end of a stated period from the grant date (which is currently approximately three years for all outstanding restricted units), 
provided we achieve an aggregate performance target for that period.  The performance target is based on a normalized 
EBITDA measure, with that measure typically being similar to the STIP measure for the year of the grant.  The target, 
however, requires achieving an aggregate performance level for the three-year period.  The grants include a minimum 
value  guarantee.    Please  see  "Item  11.  Compensation  Discussion  and  Analysis—Compensation  Components—Equity 
Awards under the LTIP." 

During the fourth quarter of 2020, it was determined the vesting performance requirement with respect to the 2020 
Grants  was  not  probable  of  being  satisfied,  and  previously  recognized  expense  for  the 2020  Grants  was  reversed.    In 
December 2020, the 2020 Grant to Mr. Tholen was canceled and the Compensation Committee approved amending the 
terms of the 2020 Grants to participants other than Mr. Tholen.  The amendments to the 2020 Grants revised the vesting 
performance  requirement  and  increased  the  number  of  restricted  units  granted  under  the  amended  2020  Grants.  The 
amended 2020 Grants vested on January 1, 2023.

In addition, in 2020 the Compensation Committee approved new 2020 service-based vesting LTIP awards. These 
awards are denominated in cash were paid 75% in February 2022 and 25% in February 2023 for all participants other than 
Mr. Tholen.  Mr. Tholen was granted a service-based vesting award denominated in cash and was paid one-half in February 
2022 and one-half in February 2023.     

These 2020 LTIP actions were taken by the Compensation Committee in recognition of the difficulty of managing 
our business through the unprecedented impacts of the COVID-19 pandemic and based on its determination that such 
actions were prudent and necessary to help retain and motivate our management team. They are described herein to provide 
details regarding the LTIP awards that are included below within the table titled "Units Vested Table for 2023." 

Supplemental Executive Retirement Plan 

Under  the  terms of  the  SERP,  participants  were  entitled  to  receive  on  December 31  of each  year  an  allocation  of 
phantom units having a fair market value equal to his or her percentage allocation multiplied by the sum of base salary 
and  cash  bonus  received  that  year,  then  reduced  by  any  supplemental  contribution  that  was  made  to  our  defined 
contribution PSSP for the participant that year.  A participant's cumulative notional phantom unit account balance earns 
the equivalent of common unit distributions.  The calculated distributions are added to the notional account balance in the 
form of additional phantom units.  All amounts granted under the SERP vest immediately and would be paid out upon the

(5)  Amounts represent the Named Executive Officer's cumulative notional account balance of phantom units valued at 
$21.18, the closing price of our common units on December 29, 2023, the final market-trading day of 2023.  The 
amounts include aggregate phantom unit quarterly distributions, changes in market value and the following aggregate 
amounts contributed since inception to each Named Executive Officer's SERP notional account balance including the 
amounts contributed in the last fiscal year shown in the table above: Mr. Craft, $670,927; Mr. Marshall, $253,302; 
Mr. Davis, $745,813; Mr. Tholen; $657,614; and Mr. Wynne, $673,959.  These amounts contributed since inception, 
other than the amounts contributed in the last fiscal year, were previously reported as compensation in the Summary 
Compensation Table in previous years if the Named Executive Officer was included in those years. On December 14, 
2023 the Compensation Committee approved termination of the SERP, and authorized distribution of accounts to 
participants on December 15, 2024 or as soon thereafter as practical.  As a result, all SERP accounts are expected to 
be settled prior to the end of the 2024 year.  The accounts will continue to accrue benefits in accordance with plan 
terms until distributed. 

Narrative Discussion Relating to the Nonqualified Deferred Compensation Table for 2023 

Supplemental Executive Retirement Plan 

Under  the  terms of  the  SERP,  participants  were  entitled  to  receive  on  December 31  of each  year  an  allocation  of 
phantom units having a fair market value equal to their percentage allocation multiplied by the sum of base salary and cash 
bonus received that year, then reduced by any supplemental contribution that was made to our defined contribution PSSP 
for the participant that year.  A participant's cumulative notional phantom unit account balance earns the equivalent of 
common unit distributions.  The calculated distributions are added to the notional account balance in the form of additional 
phantom  units.    All  amounts  granted  under  the  SERP  vest  immediately  and  would  be  paid  out  upon  the  participant's 
termination  or  death  in  ARLP  common  units  equal  to  the  number  of  phantom  units  then  credited  to  the  participant's 
account, subject to reduction of the number of units distributed to cover withholding obligations.  Please see "Item 11. 
Compensation Discussion and Analysis—Compensation Components—Supplemental Executive Retirement Plan." 

Potential Payments Upon a Termination or Change of Control 

Each of our Named Executive Officers (other than Mr. Cantrell, described below) is eligible to receive accelerated 
vesting and payment under the LTIP and the SERP upon certain terminations of employment or upon our change in control.  
Upon a "change of control," as defined in the LTIP, all awards outstanding under the LTIP will automatically vest and 
become payable or exercisable, as the case may be, in full.  In this regard, all restricted periods shall terminate and all 
performance criteria, if any, shall be deemed to have been achieved at the maximum level. The LTIP defines a "change in 
control" as one of the following events: (1) any sale, lease, exchange or other transfer of all or substantially all of our assets 
or Alliance Coal's assets to any person other than a person who is our affiliate; (2) the consolidation or merger of Alliance 
Coal with or into another person pursuant to a transaction in which the outstanding voting interests of Alliance Coal are 
changed into or exchanged for cash, securities or other property, other than any such transaction where (a) the outstanding 
voting interests of Alliance Coal are changed into or exchanged for voting stock or interests of the surviving corporation 
or its parent and (b) the holders of the voting interests of Alliance Coal immediately prior to such transaction own, directly 
or indirectly, not less than a majority of the voting stock or interests of the surviving corporation or its parent immediately 
after such transaction; or (3) a person or group being or becoming the beneficial owner of more than 50% of all voting 
interests of Alliance Coal then outstanding. 

The amounts each of our Named Executive Officers could receive under the SERP have been previously disclosed in 
"Item 11. Nonqualified Deferred Compensation Table for 2023" and the amounts each of the Named Executive Officers 
could receive under the LTIP have been previously disclosed in "Item 11. Outstanding Equity Awards at 2023 Fiscal Year 
End Table", in each case assuming the triggering event occurred on December 31, 2023.  In addition, if a Named Executive 
Officer's employment were terminated as a result of one of certain enumerated events in the SERP, the Named Executive 
Officer would receive an amount based on an allocation for the year of termination.  Please see "Item 11. Compensation 
Discussion  and  Analysis—Compensation  Components—Supplemental  Executive  Retirement  Plan"  for  additional 
information regarding the enumerated events and allocation determination.  The exact amount that any Named Executive 
Officer would receive could only be determined with certainty upon an actual termination or change in control. 

None of our Named Executive Officers are eligible for severance or change in control benefits outside of their SERP 

payments and potential equity award acceleration described above.

In connection with Mr. Cantrell's retirement in 2023, he received a settlement of his SERP account valued at $999,939 

and a $750,000 cash bonus. 

Director Compensation 

The sole member of our general partner has the right to set the compensation of the directors of our general partner.  
Typically,  such  compensation  has  been  set  by  the  Compensation  Committee  with  the  concurrence  of  Mr.  Craft,  who 
indirectly owns our general partner.  Mr. Craft, our only employee director, received no director compensation for 2023, 
and  all  compensation  that  Mr.  Craft  received  in  his  capacity  as  an  employee  is  set  forth  above  within  the  Summary 
Compensation Table.  The directors of MGP devote 100% of their time as directors of MGP to the business of the ARLP 
Partnership.

Narrative to Director Compensation Table 

Compensation for our non-employee directors includes an annual cash retainer paid quarterly in advance on a pro rata 
basis.  The annual retainer for 2023 was $185,000. In addition to the retainer, Mr. Torrence also was entitled to annual 
cash compensation in 2023 of $30,000 for service as Chairman of the Audit Committee, and Mr. Robinson and Mr. Druten 
also were entitled to additional annual cash compensation of $10,000 each for service as Chairman of the Compensation 
Committee and the Conflicts Committee, respectively.   

Prior  to  2024,  Directors  had  the  option  to  defer  all  or  part  of  their  cash  compensation  pursuant  to  the  Directors' 
Deferred Compensation Plan by completing an election form prior to the beginning of each calendar year.  No director 
elected to defer cash compensation in 2023.  On December 14, 2023 the Board of Directors approved termination of the 
Directors'  Deferred  Compensation  Plan,  and  authorized  distribution  of  accounts  on  December  15,  2024  or  as  soon

thereafter  as  practical.    Termination  rules  regarding  deferred  compensation  plans  required  termination  of  this  plan  in 
connection with termination of the SERP. 

Pursuant to the Directors' Deferred Compensation Plan, a notional account was established for deferred amounts of 
cash compensation and credited with notional common units of ARLP, described in the plan as "phantom" units.  The 
number of phantom units credited was determined by dividing the amount deferred by the average closing unit price for 
the ten trading days immediately preceding the deferral date.  When quarterly cash distributions were made with respect 
to ARLP common units, an amount equal to such quarterly distribution was credited to the notional account as additional 
phantom units.  Payment of accounts under the Directors' Deferred Compensation Plan will be made in ARLP common 
units equal to the number of phantom units then credited to the director's account. 

Directors could elect to receive payment of the account resulting from deferrals during a plan year either (a) on the 
January 1 on or next following their separation from service as a director or (b) on the earlier of a specified January 1 or 
the January 1 on or next following their separation from service.  The payment election was required prior to each plan 
year; if no election was made, the account would be paid on the January 1 on or next following the director's separation 
from service.  The Directors' Deferred Compensation Plan was administered by the Compensation Committee, and the 
Board of Directors reserved the right to change or terminate the plan at any time, provided that accrued benefits under the 
plan were not impaired. 

Upon any recapitalization, reorganization, reclassification, split of common units, distribution or dividend of securities 
on  ARLP  common  units,  our  consolidation  or  merger,  or  sale  of  all  or  substantially  all  of  our  assets  or  other  similar 
transaction that is effected in such a way that holders of common units are entitled to receive (either directly or upon 
subsequent liquidation) cash, securities or assets with respect to or in exchange for ARLP common units, the Compensation 
Committee shall, in its sole discretion (and upon the advice of financial advisors as may be retained by the Compensation 
Committee),  immediately  adjust  the  notional  balance  of  phantom  units  in  each  director's  account  under  the  Directors' 
Deferred  Compensation  Plan  to  equitably  credit  the  fair  value  of  the  change  in  the  ARLP  common  units  and/or  the 
distributions (of cash, securities or other assets) received or economic enhancement realized by the holders of the ARLP 
common units. 

CEO Pay Ratio Disclosures 

As required by Section 953(b) of the Dodd-Frank Wall Street Reform and Consumer Protection Act, and Item 402(u) 
of Regulation S-K, we are providing the following information about the relationship of the annual total compensation of 
our employees and the annual total compensation of Joseph W. Craft III, our CEO.  

For 2023, our last completed fiscal year:  

•  The median of the annual total compensation of all employees of our company (other than the CEO) was 

$109,758. 

•  The annual total compensation of our CEO, as reported in the Summary Compensation Table was $1. 
•  Based on this information, for 2023 the ratio of the annual total compensation of our CEO to the median of 

the annual total compensation of all employees was reasonably estimated to be 0.00001 to 1. 

To determine the annual total compensation of our median employee and our CEO, we took the following steps:  

•  We determined that, as of December 31, 2023, our employee population consisted of approximately 3,595 
individuals with the vast majority of these individuals located in the United States. This population consisted 
of our full-time and part-time employees, as we do not have seasonal workers.  

•  We used a consistently applied compensation measure to identify our median employee of comparing the 
amount of salary or wages reflected in our payroll records as reported to the Internal Revenue Service on 
Form W-2 for 2023.  

•  We identified our median employee for 2023 by consistently applying this compensation measure to all of 
our employees included in our analysis.  Since the vast majority of our employees, including our CEO, are 
located  in  the  United  States,  we  did  not  make  any  cost  of  living  adjustments  in  identifying  the  median 
employee.  

•  After we identified our median employee, we combined all of the elements of such employee's compensation 
for the 2023 year in accordance with the requirements of Item 402(c)(2)(x) of Regulation S-K, resulting in 

180 

 
 
 
 
 
 
 
 
 
annual total compensation of $109,758, comprised of such employee's W-2 compensation of $103,299 and 
contributions in the amount of $6,459 that we made on the employee's behalf to our 401(k) plan for the 2023 
year.  

•  With respect to the annual total compensation of our CEO, we used the amount reported in the "Total" column 

of our 2023 Summary Compensation Table.  

Compensation Committee Interlocks and Insider Participation 

Mr.  Craft,  Chairman,  President  and  CEO  of  our  general  partner,  is  also  Chairman,  President  and  CEO  of  AGP.  
Otherwise, none of our executive officers serves as a member of the board of directors or compensation committee of any 
entity  that  has  one  or  more  of  its  executive  officers  serving  as  a  member  of  the  Board  of  Directors  or  Compensation 
Committee of our general partner.

ITEM 13. 

CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS, AND DIRECTOR 
INDEPENDENCE 

Omnibus Agreement 

We are party to an omnibus agreement with MGP and AGP, which governs potential competition among us and the 
other parties to this agreement. Pursuant to the terms of the omnibus agreement, AGP and its affiliates agreed, for so long 
as Mr. Craft controls MGP, not to engage in the business of mining, marketing or transporting coal in the United States, 
unless it first offers us the opportunity to engage in a potential activity or acquire a potential business, and the Board of 
Directors, with the concurrence of its Conflicts Committee, elects to cause us not to pursue such opportunity or acquisition. 
In  addition,  AGP  has  the  ability  to  purchase  businesses,  the  majority  value  of  which  is  not  mining,  marketing  or 
transporting  coal,  provided  AGP  offers  us  the  opportunity  to  purchase  the  coal  assets  following  the  acquisition.  The 
restriction does not apply to the assets retained and business conducted by an affiliate of AGP at the closing of our initial 
public offering. Except as provided above, AGP and its affiliates are prohibited from engaging in activities wherein they 
compete directly with us.     

Related-Party Transactions 

In addition to the related-party policies and transactions discussed in "Item 8. Financial Statements and Supplementary 
Data — Note 1 — Organization and Presentation and Note 20 — Related-Party Transactions" ARLP has the following 
additional related-party transactions: 

Expense Reimbursements 

Our partnership agreement provides that MGP and its affiliates be reimbursed for all direct and indirect expenses 
incurred or payments made on behalf of us, including, but not limited to, director fees and expenses. MGP may determine 
in  its  sole  discretion  the  expenses  that  are  allocable  to  us.  Total  costs  billed  to  us  by  MGP  and  its  affiliates  were 
approximately $1.0 million for the year ended December 31, 2023. The executive officers of MGP are employees of and 
paid by Alliance Coal, and the reimbursement we pay to MGP pursuant to the partnership agreement does not include any 
compensation expenses associated with them. 

JC Land 

Alliance Coal has a time-sharing agreement with JC Land concerning Alliance Coal's use of an airplane owned by JC 
Land. In accordance with the provisions of that agreement, Alliance Coal paid JC Land $0.3 million for the year ended 
December 31, 2023 for use of the aircraft. 

Effective August 1, 2013, Alliance Coal entered into an expense reimbursement agreement with JC Land regarding 
pilots employed by Alliance Coal to operate aircraft owned by Alliance Service, Inc. and JC Land. In accordance with the 
expense reimbursement agreement, JC Land reimburses Alliance Coal for a portion of the compensation expense for its 
pilots. JC Land paid us $0.3 million in 2023 pursuant to this agreement. Separately, JC Land paid us $0.5 million during 
2023 for fuel, pilot travel, etc. paid by us on their behalf.

Director Independence 

As a publicly traded limited partnership listed on the NASDAQ Global Select Market, we are required to maintain a 
sufficient number of independent directors on the board of our general partner to satisfy the audit committee requirement 
set  forth  in  NASDAQ  Rule 4350(d)(2).  Rule 4350(d)(2) requires  us  to  maintain  an  audit  committee  of  at  least  three 
members, each of whom must, among other requirements, be independent as defined under NASDAQ Rule 4200(a)(15) 
and meet the criteria for independence set forth in Rule 10A-3(b)(1) under the Exchange Act (subject to the exemptions 
provided in Rule 10A-3(c)). 

All  members  of  the  Audit  and  Compensation  Committees—Messrs. Torrence,  Carter,  Druten  and  Robinson—are 
independent  directors  as  defined  under  applicable  NASDAQ  and  Exchange  Act  rules.  Please  see  "Item  10.  Directors, 
Executive  Officers  and  Corporate  Governance  of  the  General  Partner—Audit  Committee"  and  "Item  11.  Executive 
Compensation—Compensation Discussion and Analysis."

(1)  Audit fees consist primarily of the audit and quarterly reviews of the consolidated financial statements, but can also 
be  related  to  statutory  audits  of  subsidiaries  required  by  governmental  or  regulatory  bodies,  attestation  services 
required by statute or regulation, comfort letters, consents, assistance with and review of documents filed with the 
SEC, work performed by tax professionals in connection with the audit and quarterly reviews, and accounting and 
financial reporting consultations and research work necessary to comply with GAAP.   

(2)  Audit-related fees consist primarily of attest services related to financial reporting that are not required by statue or 

regulation but can also include accounting consultations and audits in connections with acquisitions.  

(3)  Tax fees consist primarily of services rendered for tax compliance, tax advice, and tax planning.  

The charter of the Audit Committee provides that the committee is responsible for the pre-approval of all auditing 
services and permitted non-audit services to be performed for us by our independent registered public accounting firm, 
subject to the requirements of applicable law.  In accordance with such charter, the Audit Committee may delegate the 
authority to grant such pre-approvals to the Audit Committee chairman or a sub-committee of the Audit Committee, which 
pre-approvals are then reviewed by the full Audit Committee at its next regular meeting.  Typically, however, the Audit 
Committee itself reviews the matters to be approved.  The Audit Committee periodically monitors the services rendered 
by and actual fees paid to the independent registered public accounting firm to ensure that such services are within the 
parameters approved by the Audit Committee.
