Hallador to Host Conference Call Tomorrow, June 2, at 8:30 a.m. Eastern Time

TERRE HAUTE, Ind., June 01, 2026 (GLOBE NEWSWIRE) -- Hallador Energy Company (NASDAQ:HNRG) ("Hallador" or the "Company") today announced that it has entered into an Asset Purchase Agreement ("APA") with Energy World Corporation (ASX:EWC) to acquire approximately 460 MW of Siemens gas turbines, generators, a steam turbine, and ancillary equipment for a total purchase price of $350 million, or approximately $760/kW. Hallador will also incur incremental costs for transportation, refurbishment, insurance, and logistics of approximately $100 million in connection with the delivery of the equipment to Siemens USA and then on to its Merom site. The turbines have never been previously fired and are being acquired at what the company believes to be an attractive valuation to comparable new equipment alternatives, particularly given the current delivery windows for new turbines.

The acquisition's delivered price of $450 million represents more than half the estimated total project cost for Hallador's proposed Merom simple cycle natural gas-fired combustion turbine project, which is currently advancing through MISO's ERAS interconnection process. The transaction secures critical long-lead time equipment in a market characterized by significant supply constraints and extended lead times for new turbine deployment.
