Arch Resources and Consol Energy are combining to form a single coal producer valued at more than $5 billion

Arch Resources and Consol Energy are combining to form a single coal producer valued at more than $5 billion, the companies announced Wednesday, the latest consolidation in a deal-happy energy sector.

Arch shareholders will get 1.326 shares of Consol common stock for each share of Arch they own. Consol shareholders will own about 55% of the new company — to be called Core Natural Resources — and Arch shareholders will own about 45%.

Cole Natural Resources will be based in Canonsburg, Pa., just southwest of Pittsburgh, which is the current headquarters of Consol Energy. Arch is based in St. Louis.

Consol Energy CEO and chairman will be the company's executive chairman and Arch CEO Paul Lang will be its chief executive.

If approved by shareholders and regulators, the deal is expected to close in the first quarter of 2025.

Shares of Arch rose 5.9% Wednesday, while shares of Consol rose 7.9%.

Arch and Consol said that Core Natural Resources will benefit from between $110 million and $140 million of annual cost and operational synergies within 18 months of the deal's closing.

Arch had revenue of $3.1 billion in 2023, while Consol brought
