FOR IMMEDIATE RELEASE

Stacker Reclaimer Equipment at Dominion Terminal Associates Damaged by High Winds

BRISTOL, Tenn., June 18, 2026 – Alpha Metallurgical Resources, Inc. (NYSE: AMR), a leading U.S. supplier of metallurgical products for the steel industry, today announced that a key piece of equipment at Dominion Terminal Associates (DTA) in Newport News, Va. sustained significant damage as a result of high winds in Sunday evening’s storm. The equipment, a stacker reclaimer machine, is one of two such devices at DTA used to move coal into and out of stockpiles at the terminal. The second stacker reclaimer machine, which was refurbished earlier this year, remains intact and operational.

At this time, DTA officials are working to understand the scope of the damage to the stacker reclaimer, which sustained wind gusts of more than 80 miles per hour during an evening storm on June 14. The machine is currently inoperable. As a result, Alpha has sent force majeure letters to affected customers. With a 65% majority ownership interest in DTA, Alpha utilizes the terminal for most of its export shipments but maintains additional shipping capacity at neighboring terminals.

Terminal leaders are working to determine a timeline and plan of action for the damaged stacker reclaimer.
