Alliance Resource Partners

Alliance Resource Partners, L.P. (ARLP) is a U.S. diversified energy and natural-resource partnership. The company describes itself as a provider of reliable, affordable baseload energy for domestic and international markets. Its common units trade on the NASDAQ Global Select Market under the ticker ARLP. The partnership says it has more than two decades of operational experience and identifies 1999 as the beginning of its partnership history. Coal operations are a central part of the business. Alliance says it is the second-largest coal producer in the eastern United States and operates seven underground mining complexes. Its coal products include thermal and metallurgical grades, with differing heat and sulfur characteristics. The company says these products serve utility, industrial, and steelmaking customers in domestic and international markets, including electric power generation markets. The partnership also earns income from mineral interests. Its portfolio includes oil and gas mineral and royalty interests in strategic producing regions across the United States, which it offers for lease to major operators. Development and leasing of those interests generate royalty income. Alliance also receives coal royalty income from reserves and resources it owns and leases to its mining operations. Beyond coal and royalties, Alliance describes a category of other growth investments intended to support the development of technology, energy, and related infrastructure. Its stated strategy presents these investments alongside its existing coal and royalty operations as part of a broader portfolio positioned to respond to evolving demand for energy solutions. The company reports that it produced 33.2 million tons in 2025 and held 115,680 net oil and gas royalty acres. Its website also reports approximately $4.9 billion in distributions since the partnership’s inception.

Alliance Resource Partners is a U.S. coal and natural-resources company organized as a master limited partnership. The partnership identifies 1999 as its inception and says it has accumulated more than two decades of operating experience. It is not simply a coal-mining name: the company describes a broader business comprising coal production, mineral and royalty interests, and other growth investments. Coal operations form a major part of its business. Alliance reports that it is the second-largest coal producer in the eastern United States and operates seven underground mining complexes. It produces thermal and metallurgical coal with varying heat and sulfur characteristics. According to the company, this range allows it to address customer specifications across utility, industrial, and steelmaking uses. Its markets include domestic and international customers, and the company frames its coal operations as contributing to reliable and affordable power supply. Alongside mining, Alliance has developed a portfolio of mineral and royalty interests. The company says it owns oil and gas mineral interests in strategic producing regions across the United States and markets them for lease to major operators. Leasing and development generate royalty income. It also earns coal royalty income from mineral reserves and resources that it owns and leases to its coal mining operations. These activities give the partnership income sources in addition to coal production. The company also identifies other growth investments as a business area. Its stated aim for these investments is to support the growth and development of technology, energy, and related infrastructure, positioning the portfolio in relation to changing demand for energy solutions. The available company material does not provide a dated account of individual investment transactions or identify specific executives or founders, so those details are not included here.
