The above coal inventory balances reflect lower of cost or net realizable value adjustments of $9.7 million and $8.3 million as of June 30, 2026 and December 31, 2025, respectively. The adjustment as of June 30, 2026 is primarily a result of higher cost per ton at the Mettiki Coal, LLC and Mettiki Coal (WV), LLC (collectively “Mettiki”) mining complex due to reduced production following the decision to cease longwall production. The adjustment as of December 31, 2025

is the result of higher cost per ton at the Mettiki mining complex due to lower production and challenging geological conditions in the longwall panel that reduced coal recovery.
