Alliance Resource Partners entered definitive agreements to acquire general partner and limited partner interests in AllDale Minerals III and IV for approximately $206.2 million, expanding its oil and gas royalties platform with 48,500 net royalty acres across premier basins. The transaction increases ARLP's economic interest in AllDale from 5% to 61% and enhances its Permian, Anadarko, Bakken, and Haynesville positions while de-risking its existing minerals portfolio.
