Hallador Energy Enters Material Agreement, Discloses Details in 8-K

Hallador Energy Co. (HNRG) filed a Form 8-K with the SEC on June 2, 2026, stating it had entered into a material definitive agreement, per Item 1.01 of the filing.

The Terre Haute, Indiana-based company, which operates coal mines and a power plant in Indiana and Illinois, disclosed the agreement under Item 1.01 while also furnishing information under Item 7.01 Regulation FD Disclosure and attaching exhibits under Item 9.01.

The filing does not publicly name the counterparty or the precise dollar value of the contract in the summary data released through EDGAR.

Prior to the filing, no public disclosure of this specific agreement existed in SEC records for Hallador. The new state is that the company is now bound by the contract’s terms, which typically include performance milestones, delivery schedules or financing covenants depending on whether the agreement is a coal supply pact, equipment financing or partnership arrangement.

The change took legal effect on or before the June 2 filing date.

Downstream, Hallador must adhere to any notice, reporting or closing conditions spelled out in the agreement. Material definitive agreements of this type often require the company to file the full contract or material amendments as an exhibit in a subsequent 8-K or 10-Q within four business days of any triggering event.

Counterparties to the agreement now operate under its covenants, which can affect coal delivery volumes to utilities, credit facility compliance or joint-venture funding draws. Standard SEC rules give Hallador until its next quarterly report to provide any required financial statement impact from the transaction.

This is the latest in a series of 8-K filings by Hallador detailing operational contracts as the company manages its coal production assets following earlier shifts in the domestic thermal coal market. The original disclosure framework for Item 1.01 was established under SEC regulations finalized in 2004 to accelerate reporting of events material to investors.
