"Mitsubishi Corporation (“MC”) has agreed to acquire all equity interests in Aethon III LLC, Aethon United LP, and related entities and interests (collectively “Aethon”). This transaction marks MC’s entry into the U.S. shale gas business across the value chain, from upstream ownership through domestic sales and export of produced gas.
MC reached an agreement on January 16, 2026 with Aethon Energy Management and Aethon’s existing stakeholders, including Ontario Teachers’ Pension Plan, RedBird Capital Partners for a total equity investment of approximately USD 5.2 billion. The acquisition is expected to close in the first quarter of Japan’s fiscal year (April to June of 2026), subject to customary regulatory approvals."
Aethon has nine producing Western Haynesville wells, all located in Robertson County. They are currently drilling another well in Robertson, and have approved permits for five more (two in Robertson and three in Leon).
