Alliance Resource Partners LP is 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 key producing regions across the United States. The company maximizes the value of its mineral asset base through coal production from its mining operations and through the leasing and development of its coal and oil & gas mineral interests. Alliance Resource Partners LP provides reliable, baseload fuel for electricity generating customers while positioning itself for long-term growth through investments in energy and related infrastructure.
Alliance Resource Partners LP generates revenue primarily from coal sales and oil & gas royalty income. The company markets its coal production to major domestic and international utilities and industrial customers, with a significant portion of volumes sold under long-term coal supply agreements. Additionally, Alliance Resource Partners LP markets its oil & gas mineral interests for lease to operators in regions such as the Permian, Anadarko, and Williston Basins, generating royalty income from their development, and earns intercompany royalty income through the leasing and development of its coal mineral reserves and resources to its mining complexes.
The company operates through the following segments: Coal Mining Operations, Oil & Gas Royalties, Coal Royalties, and Other Growth Investments.
- Coal Mining Operations: This segment produces bituminous coal from underground mines in the Illinois Basin and Appalachia regions, selling primarily into thermal and metallurgical markets. Alliance Resource Partners LP operated seven underground mining complexes across Illinois, Indiana, Kentucky, Maryland, Pennsylvania, and West Virginia as of December 31, 2025, including the Gibson, River View, Hamilton, Warrior, Tunnel Ridge, Mettiki, and MC Mining complexes. The segment sold 33.0 million tons of coal in 2025, with 89.2% sold to domestic electric utilities and 8.6% into international markets.
- Oil & Gas Royalties: This segment generates royalty income from oil & gas mineral interests held directly or indirectly by Alliance Minerals, including its equity interest in AllDale III. The company owns mineral and royalty interests in approximately 70,000 net royalty acres, primarily in the Permian, Anadarko, and Williston Basins, and markets these interests for lease to operators in those regions. Alliance Resource Partners LP receives an upfront lease bonus and retains a royalty interest entitling it to a fixed percentage of production or revenue from the underlying acreage, with production totaling 1,628 MBbls of oil, 6,674 MMcf of natural gas, and 908 MBbls of natural gas liquids in 2025.
- Coal Royalties: This segment includes approximately 509.6 million tons of coal mineral reserves and substantially all of the 1.07 billion tons of coal mineral resources owned or leased by Alliance Resource Properties. Alliance Resource Partners LP leases these reserves and resources to its mining complexes under long-term leases, granting lessees the right to mine and sell coal in exchange for royalty payments based on a percentage of sale price or a fixed royalty per ton. The segment generated coal sales of 20.5 million tons from the Illinois Basin and 3.6 million tons from Appalachia in 2025.
- Other Growth Investments: This segment includes strategic investments in technology and energy-related infrastructure to leverage core competencies and build platforms for future lines of business. Alliance Resource Partners LP holds investments in Matrix Group, which develops and markets industrial, mining and technology products and services worldwide, and Bitiki, which mines bitcoin and hosts third-party crypto-miners for a fee. The company has also invested in Infinitum, a Texas-based developer of electric motors with printed circuit board stators; NGP ET IV, which focuses on energy transition investments; and Gavin Generation, which owns an indirect interest in a joint venture holding company that operates a coal-fired power plant.
Alliance Resource Partners LP is the second largest coal producer in the eastern United States, competing with companies such as American Consolidated Natural Resources Inc., Core Natural Resources Inc., Alpha Metallurgical Resources Inc., Foresight Energy Resources LLC, and Peabody Energy Corporation.
