Mitsubishi Corporation (MC) has agreed to acquire all equity in Aethon III, Aethon United, and related entities for approximately $5.2 billion, marking its entry into the US shale gas sector.

The acquisition, expected to close in Q1 of Japan’s fiscal year 2026, spans upstream production, domestic sales, and LNG exports.

Aethon’s Haynesville Shale assets in Texas and Louisiana produce around 2.1 Bcfd, supplying the southern US market and potential LNG exports to Asia and Europe. The deal strengthens MC’s integrated North American energy platform, complementing existing upstream, midstream, LNG, and power generation operations.
