BlackRock, Inc. Reports 4.98% Ownership Stake in Hallador Energy Co (HNRG) via Amendment

BlackRock, Inc. filed a Schedule 13G/A on April 27, 2026, disclosing its beneficial ownership in Hallador Energy Co (HNRG). As of the event date on March 31, 2026, BlackRock reported owning 2,343,118 shares of common stock, representing a 4.98% stake in the company. This filing serves as an amendment (Amendment No. 1) to a previous disclosure, indicating an increase from a reported 0.0% position in the prior period. The reporting person, BlackRock, Inc., maintains sole voting power over 2,300,206 shares and sole dispositive power over the full 2,343,118 shares. The filing specifies that the securities were acquired in the ordinary course of business and not for the purpose of influencing or changing the control of the issuer. Because the ownership level has fallen below the 5% threshold, this filing effectively serves as a notice that BlackRock is no longer a greater-than-5% beneficial owner, despite the technical increase in shares compared to the previous zero-value snapshot.
