Hallador Secures Up to $675 Million Debt Financing for Turtle Creek Gas

Facilities Expected to Fund the Majority of Turtle Creek’s Sub-$800 Million Estimated Project Cost

Company’s $2.4 Billion Contracted Forward Sales Position and Expected Operating Cash Flow Provide Credible Pathway to Fully Fund Turtle Creek

TERRE HAUTE, Ind., Sept. 17, 2026 (GLOBE NEWSWIRE) -- Hallador Energy Company (Nasdaq: HNRG) (“Hallador” or the “Company”) today announced that on September 15, 2026, the Company closed a $600 million senior secured term loan facility (the “Term Loan Facility”) with a three-year term and, subject to lender approval, a two-year extension option. The Term Loan Facility consists of approximately $550 million funded at closing and an additional $50 million delayed draw term loan commitment available for up to 12 months. In connection with the Term Loan Facility, the Company also has the ability to establish a super-priority revolving credit facility of up to $75 million with a similar tenor, creating a financing package (collectively, the “Facilities”) of up to $675 million.

Hallador expects to use borrowings from the Facilities primarily to fund upcoming payment obligations under its turbine asset purchase agreement, transportation and refurbishment costs, pre-notice-to-proceed and other development costs, and construction of the Company’s proposed new and efficient 460-megawatt natural gas fired Turtle Creek Gas project (“Turtle Creek”), which has an expected total project cost of less than $800 million. Approximately $120 million of the proceeds from the Term Loan Facility will be used to repay the Company’s existing $45 million term loan and $75 million revolving credit facility. Proceeds will also be used for general corporate purposes.

The Company believes the Facilities represent the largest component of its overall financing plan for Turtle Creek and address the majority of Turtle Creek’s expected capital requirements. The Company is actively evaluating and expects to pursue additional financing sources to strengthen its capital structure. Together with the operating cash flow Hallador expects to generate between now and commercial operation of Turtle Creek, supported by the Company’s contracted forward sales position, management believes the Company has a credible pathway and sufficient time to fully fund the project consistent with its objective of little to no equity dilution.

“Closing this loan is the largest single step in financing Turtle Creek,” said Brent Bilsland, Chairman and Chief Executive Officer. “We chose this structure because it carries more debt than traditional bank project financing would typically allow. We are paying a higher rate for that capital, and we accept the trade. As Turtle Creek approaches and enters commercial operation, we expect to be able to refinance the loan on terms that reflect an operating plant.”

Bilsland continued, “Turtle Creek would continue Hallador’s transformation into a multi-fuel independent power producer and expand the scale of our power generation business. By leveraging existing infrastructure and critical generation equipment we have under contract, we believe we have positioned Turtle Creek to reach commercial operation on an accelerated timeline and at a capital cost well below comparable new generation projects. With demand for reliable, dispatchable power continuing to grow in MISO, we believe the combination of speed to market and capital efficiency makes Turtle Creek a compelling opportunity for Hallador and its shareholders. What the team remains focused on executing is straightforward but not assured: the turbines have to load, clear export, and be refurbished on schedule, and we have to contract the plant’s output at prices that justify the cost, as we have done at Merom.”

Kennedy Lewis Investment Management LLC provided the Term Loan Facility.

Turtle Creek Project Update

Development of Turtle Creek continues to progress. While certain development milestones have taken longer than initially anticipated, none has changed the Company’s view of the project’s economics or its targeted commercial operation date. Turbine shipment activities remain on schedule, and the Company expects to complete the purchase of the equipment in accordance with the terms of the previously filed turbine asset purchase agreement. The equipment is then expected to be transported to Siemens’ U.S. facilities for refurbishment in the coming months.

Hallador’s remaining development milestones continue to advance. The Company expects to execute the Generator Interconnection Agreement (“GIA”) in the coming weeks. Negotiations on the project’s engineering and construction agreement are in their final stages..

Hallador does not expect a long-term power purchase agreement to be a condition to its final investment decision (“FID”). As of June 30, 2026, the Company had approximately $2.4 billion of contracted forward sales under multi-year agreements with utilities and other counterparties. The Company believes this contracted position provides the foundation to proceed to FID on Turtle Creek. As a new natural gas-fired resource, Turtle Creek is expected to be attractive to counterparties seeking long-duration dispatchable supply, and discussions with prospective counterparties for Turtle Creek’s output are ongoing.

Turtle Creek, like the Company’s Merom Generating Station, is located in the MISO market. The Company believes current MISO market pricing for capacity and energy is supportive of new dispatchable generation, and its decision to advance Turtle Creek toward FID reflects that view.
