Core Natural Resources Inc: Mohnish Pabrai is betting 25% of his US portfolio.

Core Natural Resources Inc. (CNR) is a name that’s quietly making waves in the investing world. With a $4.04 billion market cap and deep roots in coal mining dating back to 1864, this company just underwent a major transformation. After a merger of equals between CONSOL and Arch Resources in early 2025, the new entity has emerged with serious momentum. Legendary investor Mohnish Pabrai has taken notice—allocating a staggering 25% of his U.S. portfolio to this single coal stock. That’s not just a bet. It’s a conviction.
