Alliance Resource Partners to Buy AllDale Minerals Interests in $206 Million Deal
The acquisition gives the coal producer a broader foothold in the Permian Basin and a new entry point into the Haynesville shale, positioning it to capture long-term LNG export demand.
Alliance Resource Partners, L.P. (ARLP) agreed to acquire certain general partner and limited partner interests in AllDale Minerals III, LP and AllDale Minerals IV, LP for $206.2 million in an asset-purchase transaction, the company said. The deal is expected to close in July 2026.
The acquisition accelerates the continued growth of ARLP's Oil & Gas Royalties segment, adding scale and development upside across multiple U.S. basins anchored by a meaningful Permian position, according to the company. It also expands the partnership's natural gas footprint with entry into the Haynesville, a resource play positioned to benefit from long-term LNG export demand growth.
"This acquisition accelerates the continued growth of our Oil & Gas Royalties segment. The AllDale III & IV portfolio adds scale and development upside across multiple U.S. basins, anchored by a meaningful Permian position. It also expands our natural gas footprint with entry into the Haynesville, a resource play well-positioned to benefit from long-term LNG export demand growth," said Joseph W. Craft III, Chairman, President and Chief Executive Officer.
The deal lands amid a sustained wave of mineral and royalty consolidation in U.S. shale basins. Kimbell Royalty Partners in May agreed to a $147 million cash-and-unit acquisition of Permian Basin mineral and royalty interests from Mesa Royalties, a portfolio of NGP-managed funds, targeting over 2,300 gross producing wells and more than 600 undeveloped locations. Earlier, Kimbell paid roughly $231 million for interests concentrated on the Mabee Ranch in the Midland Basin's Martin and Andrews counties. Texas Pacific Land Corporation closed a $286 million cash purchase of Permian mineral and royalty interests spanning approximately 7,490 net royalty acres, primarily in the Midland Basin, in late 2024.
The AllDale portfolio gives Alliance Resource Partners a diversified royalty base that complements its existing coal operations while deepening exposure to oil-weighted production in the Permian and gas volumes in the Haynesville. The Haynesville position, in particular, aligns with the basin's role as a key supply source for Gulf Coast liquefied natural gas facilities, where export capacity is expected to expand materially over the coming decade.
The transaction is subject to customary closing conditions. Alliance Resource Partners did not disclose expected accretion or integration synergies in its announcement.
