Core Natural Resources, Inc. filed Amendment No. 1 to its Annual Report for the year ended December 31, 2025. The sole purpose is to amend Item 15 and Exhibit 96.1 by filing an updated Technical Report Summary for the Leer Complex in West Virginia.
The company explains that the original Technical Report Summary contained incorrect images for Figure 6.3-1 (Stratigraphic Column) and Figure 7.5-1 (Drillhole Collar Locations, Map View). The underlying text and conclusions of the report are unchanged, and no new financial statements are included. As of June 30, 2025, the aggregate value of common stock held by non-affiliates was approximately $3,514,239,816, and shares of common stock outstanding totaled 50,979,544 as of January 30, 2026.
Core Natural Resources, Inc. director Holly K. Koeppel filed an amended Form 4 to correct her reported direct ownership of common stock. A prior Form 4 contained immaterial clerical rounding errors, and the corrected total number of shares directly beneficially owned is now reported as 14,970.
Core Natural Resources, Inc. director Joseph P. Platt Jr. filed an amended insider report to correct a previously misstated share balance. The amendment explains that an earlier Form 4 contained immaterial clerical rounding errors in the total number of common shares directly beneficially owned.
The corrected figure shows that Platt directly owns 40,660 shares of common stock, par value $0.01 per share. The filing does not reflect a new purchase or sale of shares, but instead updates the reported ownership amount to the accurate total.
