Alliance Resource Partners, L.P. Provides Operations Update

Alliance Resource Partners, L.P. (NASDAQ: ARLP) previously announced several actions it was taking in response to the rapidly evolving impact of the COVID-19 pandemic, including temporarily ceasing coal production at all of its Illinois Basin mines (see March 30, 2020 Press Release). At that time, the temporary idling was scheduled to last through April 15, 2020, subject to change based on the business needs of our customers. Based on available data and customer feedback as of today, ARLP has determined that anticipated coal supply requirements can be met currently from remaining inventory at its Illinois Basin mines, and has temporarily extended the previously announced cessation of coal production at those operations through April 26, 2020.

In addition, ARLP ceased coal production at its MC Mining operation in east Kentucky in early April, and will supply coal to its customers from existing inventory until coal production is transitioned to the new Excel Mine No. 5, which is expected to occur in early May 2020. Coal production is continuing at ARLP’s Northern Appalachian mines. To protect employees, these operations have implemented numerous safeguards including staggered shift patterns to promote social distancing, enhanced cleaning procedures, promotion of recommended hygiene practices and limiting workplace access.

As ARLP continues to assess the impact of the COVID-19 pandemic, as well as its ability to continue to meet customer needs from existing coal inventories at the affected operations, the actual return to production will be accelerated or extended if needed. ARLP intends to provide a status update with its report of financial and operating results for the quarter ended March 31, 2020.
