Company history
Alliance Resource Partners’ business roots date to 1971, when MAPCO acquired the Dotiki mine. In 1996, management formed Alliance Coal Corporation and acquired MAPCO’s coal operations. Alliance Resource Partners was formed in May 1999, completed its initial public offering on August 19, and acquired substantially all of Alliance Resource Holdings’ coal-production and marketing assets. Joseph W. Craft III became president and chief executive officer that August.[19][20][21]
The partnership expanded through acquisitions and mine development: it acquired the Warrior mining complex in 2003, began production at the River View mine in 2009, and acquired White Oak’s remaining equity in the Hamilton mine in 2015 after supporting its development through earlier transactions. In 2017–2018, it completed transactions that changed its partnership structure and eliminated general-partner net-income allocations. Craft, CEO since 1999, became chairman on January 1, 2019.[22][23][24][25][26][27][21] [20][21][22][23][24][25][26][27][19]
