TERRE HAUTE, Ind., November 10, 2025 – Hallador Energy Company (Nasdaq: HNRG) (“Hallador” or the “Company”) today reported its financial results for the third quarter ended September 30, 2025.

“This was an exceptional quarter for Hallador as we delivered significant gains across all key financial metrics, including material growth in revenue, net income, Adjusted EBITDA and cash flow from operations,” said Brent Bilsland, President and Chief Executive Officer. “Favorable summer weather, increased energy demand, and stronger natural gas prices provided a supportive backdrop that drove strong revenue at Hallador Power. Following the completion of our second unit’s planned maintenance early in the quarter, both generating units operated efficiently throughout the summer, while our coal operations continued to deliver solid production, increased shipments, and stable operating costs. The combination of higher dispatch levels and strong operational execution helped reduce inventories and meaningfully enhanced our financial performance.”

“We continue to see accelerating demand for accredited capacity, particularly from data center developers and load serving entities seeking dispatchable energy. The strength of this interest led us in early November to file an application seeking to expand our generation capabilities at the Merom site by 525 MWs through MISO’s Expedited Resource Addition Study (ERAS) program. ERAS aims to fast-track critical capacity additions to the grid and we are currently targeting an on-line date for the gas generation in the fourth quarter of 2028.”

Bilsland continued, “the combination of the ERAS application and the positive progress towards a long-term agreement in support of large load development is providing a definitive pathway for meaningful company growth. If we are able to execute on these growth initiatives, adding roughly 50% additional generating capacity to the Merom site should provide exceptional value to our shareholders now and in the future.”

Adjusted EBITDA should not be considered an alternative to net income, income from operations, cash flows from operating activities or any other measure of financial performance presented in accordance with GAAP. Our method of computing Adjusted EBITDA may not be the same method used to compute similar measures reported by other companies.
