Alliance Resource Partners, L.P. (NASDAQ:ARLP) ("ARLP" or the "Partnership") today announced that it has entered into definitive agreements to acquire certain general partner and limited partner interests in AllDale Minerals III, LP and AllDale Minerals IV, LP (collectively, "AllDale III & IV") for approximately $206.2 million, subject to customary closing price adjustments.

The transaction implies an aggregate gross valuation for AllDale III & IV of approximately $410.0 million. The general partner and limited partner interests being sold by the third-party selling interest holders are valued at approximately $306.2 million, with $206.2 million of the interests to be acquired by ARLP and $100.0 million of the interests to be acquired by related parties of Joseph W. Craft III, ARLP's Chairman, President and Chief Executive Officer.

The difference between the $410.0 million aggregate gross valuation and the $306.2 million value of interests being acquired reflects existing interests already owned by ARLP and related parties of Mr. Craft.

Upon closing, ARLP's aggregate economic interest across AllDale III & IV is expected to increase from approximately 5% to 61% and ARLP, through a wholly owned subsidiary, is expected to own 100% of the general partner interests of AllDale III & IV, that will be non-economic post-closing.

The agreements provide for an effective date of April 1, 2026, and the transaction is expected to close during July 2026, subject to customary closing conditions. Given the participation in the transaction by related parties of Mr. Craft, the terms of the transaction were approved by the conflicts committee of the Board of Directors of ARLP's general partner, which is comprised entirely of independent directors.
