Warrior Met Coal : Mine Safety Disclosure - Form 8-K

Item 1.04 Mine Safety - Reporting of Shutdowns and Patterns of Violations.

Section 1503 of the Dodd-Frank Wall Street and Consumer Protection Act (the "Act") requires a Current Report on Form 8-K if a company is issued an imminent danger order under Section 107(a) of the Federal Mine Safety and Health Act of 1977 (the "Mine Act") issued by the federal Mine Safety and Health Administration ("MSHA").

On September 22, 2023, Warrior Met Coal Mining, LLC, a subsidiary of Warrior Met Coal, Inc. (the "Company") received an imminent danger order under Section 107(a) of the Mine Act at Mine No. 4. On that date, an MSHA representative allegedly observed non-permissible equipment being operated in a restricted area. Mine No. 4 management personnel immediately mitigated the situation. No injuries resulted from the condition and production at the mine was briefly interrupted but has resumed. The Company reserves the right to contest the 107(a) order and any accompanying citations.
