#### ITEM 1.04 MINE SAFETY – REPORTING OF SHUTDOWNS AND PATTERNS OF VIOLATIONS
On April 1, 2026, River View Coal LLC, an indirect subsidiary of Alliance Resource Partners, L.P. (the "Partnership"), received an imminent danger order from the Mine Safety and Health Administration ("MSHA") under Section 107(a) of the Federal Mine Safety and Health Act of 1977 at the River View Mine (Mine ID No. 15-19374).

The order related to maintenance work on a shuttle car that MSHA determined was not adequately blocked against motion.

The Partnership reserves the right to contest the order and any related citation or proposed assessment.
