Our History & Heritage

A Merger of Equals
Core Natural Resources was established in January 2025 as a merger of equals between Arch Resources and CONSOL Energy. In 2023, before joining forces, Arch and CONSOL together sold approximately 101 million tons of coal to steelmaking, industrial and power-generation customers. Their combined 2023 revenues were approximately $5.7 billion.
Diverse & Complementary Coal Offerings
Both CONSOL Energy and Arch Resources share a proud and long heritage as innovative leaders in the U.S. mining industry. With Arch’s focus on metallurgical products and CONSOL’s emphasis on industrial, power generation, and marine terminal operations, the company’s combined product offerings are both complementary and diverse, providing exceptional value to our customers.

CONSOL Energy
CONSOL and its predecessors have been mining coal since 1864, powering the nation with affordable, abundant, reliable domestic energy, while creating family-sustaining jobs, and keeping our nation competitive in the global marketplace. With over 160 years of adapting to market trends and industry needs, CONSOL is no stranger to change. Now as Core Natural Resources, the company has once again successfully evolved. As a result of the merger with Arch Resources, the new entity will have access to key growth industrial markets such as steel, cement, and brick manufacturing while being well positioned to serve the resurgent power generation demand driven by artificial intelligence (AI), data centers, and electric vehicle (EV) expansion.
From the Industrial Revolution to the AI Revolution
As the world moves steadily closer to a lower-carbon economy, electrification, and AI adoption, Core is ideally situated to satisfy global needs as a responsible energy transition plays out over decades to come.

Arch Resources
Arch Resources has successfully transitioned into global coking coal markets in recent years after focusing principally on thermal markets during its first decades of existence. Established in 1969, the company completed a successful merger of equals in 1997 between Arch Mineral and Ashland Coal to form Arch Coal, later changing its name to Arch Resources to underscore the growing importance of its metallurgical production in its sales mix. In recent years, the company has become a leading U.S. producer of metallurgical coal for sale to international and U.S. steel producers. Complementing that metallurgical position, Arch’s West Elk mine produces high-rank, low-sulfur thermal coal for export into international markets via ports on both the West Coast and Gulf of Mexico, as well as for sale to industrial customers in North America. Arch’s Powder Basin operations are anchored by the Black Thunder mine, which is one of the largest coal mines in the world.
Achieving Economies with the Immense Benefits of Coal
The merger of Arch Resources and CONSOL Energy into Core Natural Resources holds the promise of bringing even more meaningful benefits to emerging societies around the world, while also achieving greater efficiencies, market reach, and sustainability achievements.
The IEA estimates the global demand for coal has increased 16% since 2020.
