Mitsubishi Corporation has agreed to acquire all equity interests in Aethon III LLC, Aethon United LP and related entities, marking its entry into the US shale gas sector across the value chain. The acquisition involves an equity investment of about USD 5.2 billion and is expected to close in the first quarter of Japan’s FY 2026, subject to regulatory approvals.

The assets, operated by Aethon Energy Management, are located in the Haynesville shale across Louisiana and Texas and produce around 2.1 billion cubic feet per day of natural gas. The region offers strong access to LNG export terminals, including Cameron LNG, where Mitsubishi Corporation holds liquefaction capacity. The investment aligns with the company’s Corporate Strategy 2027 to build an integrated US energy value chain spanning gas, LNG, power and downstream businesses.
