Hallador Energy Signs Six-Year Power Deal With Duke Energy Indiana

What happened

Hallador Energy Company said in an 8-K filing that its wholly owned subsidiary, Hallador Power Company, LLC, entered into two agreements with Duke Energy Indiana, LLC on October 7, 2026.

The first is a six-year Power Purchase Agreement covering an annual average of 200 megawatts of electricity from Hallador's Merom Generating Station, running June 1, 2029 through May 31, 2035. The filing describes the PPA as "unit contingent," meaning deliveries follow the actual output of Merom's two generating units and Hallador Power is not obligated to buy replacement power when a unit is offline or under maintenance. Duke Energy Indiana may also reduce purchases to zero for up to 90 days per contract year, subject to seasonal limits.

The second agreement, under the companies' existing Master Power Purchase and Sale Agreement, has Hallador Power selling Zonal Resource Credits to Duke Energy Indiana over the same six-year window. Duke Energy Indiana will pay approximately $271 million for those credits over the term.

Hallador Energy reported $469.5 million in revenue for the year ended December 31, 2025, according to the most recent annual figure. The company is classified as an electric services business and its common shares trade on Nasdaq under the ticker HNRG.

The terms

Under the PPA, pricing is based on a Fuel Price Floor and a seasonal Base Adder, both of which increase over the contract term, with provisions allowing recovery of certain excess fuel costs.

Hallador Power must maintain standby letters of credit to secure its obligations under both agreements. For the PPA, the letter of credit starts at $3.5 million, rises to $7.0 million in January 2029, falls to $4.5 million in June 2031, then to $2.7 million in June 2033 through the end of the agreement. For the MPPSA, it starts at $6 million, rises to $12 million in January 2029, then falls to $8 million in June 2031 and $3 million in June 2033.

The company said the descriptions in the filing are summaries and that it expects to file the full agreements as exhibits to its next Quarterly Report on Form 10-Q.

What this means

A Form 8-K is the current report a US public company files when a significant event occurs between its regular quarterly and annual reports. The form is organized by numbered "items," and each one represents a different category of event. This filing cites Item 1.01, entry into a material definitive agreement; Item 2.03, creation of a direct financial obligation; Item 7.01, Regulation FD disclosure; and Item 9.01, financial statements and exhibits.

Item 2.03 is triggered here because the standby letters of credit create a financial obligation for Hallador Power. A standby letter of credit is a promise from a bank that it will pay a beneficiary if the company fails to meet its contractual duties. It is a form of credit support rather than a loan the company draws on for operations. The amounts in this case step up shortly before the delivery period begins in 2029 and step down as the contract runs toward its 2035 end, which is a common pattern when a counterparty wants more protection early in a long-term supply arrangement. The filing does not state why the credit amounts follow that schedule.

A Power Purchase Agreement is a long-term contract to buy and sell electricity. It gives the seller a defined outlet for power and the buyer a defined supply, often years in advance of delivery. This PPA is "unit contingent," which shifts output risk to the buyer: if Merom's units are down, Hallador Power does not have to procure electricity elsewhere to fulfill the contract, and Duke Energy Indiana assumes that the plant may not always be available.

A Zonal Resource Credit is a tradable credit representing accredited generating capacity under MISO, the Midcontinent Independent System Operator, the regional grid organization that coordinates the electric system across parts of the central US. In the MISO capacity market, load-serving entities buy these credits to demonstrate they have enough capacity to meet expected demand. Here, Hallador Power is selling credits tied exclusively to the two Merom units at a rate of 225 per day on an annual average — a separate revenue stream from the electricity the same units will produce under the PPA.

Item 7.01, Regulation FD disclosure, relates to Regulation Fair Disclosure, an SEC rule requiring that material information disclosed to certain outside parties also be made public. Companies use Item 7.01 to furnish press releases and similar materials alongside their filings, which is why the October 8 press release is attached as Exhibit 99.1. Information furnished under Item 7.01 is not treated as "filed" under the securities laws unless a company says otherwise.

The filing does not state why Hallador Energy entered these agreements, and the sources here do not include the press release text, so that reason is not established. The agreements themselves do not begin until June 2029; between now and then the disclosed obligations are the letters of credit, which take effect earlier under the schedule set out in the filing.
