ENEOS Holdings - Company History

JX Holdings was assembled in April 2010 out of two companies that could not carry a shrinking market alone: Nippon Oil, the largest of Japan's primary distributors, and Nippon Mining Holdings, which brought a non-ferrous metals business with it. The new group set out to cut the industry's surplus refining capacity from a position of overwhelming share — and then watched crude collapse, taking it to operating losses in the years to March 2015 and March 2016 and making a second, larger merger unavoidable.

Taking TonenGeneral Sekiyu in April 2017 gave one company about 51 per cent of Japan's refining and marketing — a share no domestic energy business had held before — and the combination showed up immediately in operating profits of $4.4B (¥488bn) and $4.9B (¥537bn). Three years later the group put the petrol-station brand on the parent itself and became ENEOS Holdings, just as the pandemic wiped out the earnings the merger had lifted.

Record earnings in the year to March 2022 — an operating profit of $6.0B (¥786bn) — gave way at once to the reversal of inventory effects, and the decade turned into one of subtraction: the Wakayama refinery shut, two chief executives lost for the same kind of misconduct, the electricity, materials and renewables businesses split out beneath the holding company, and JX Metals floated in March 2025. The company that had led the industry's consolidation was now choosing among its own businesses on the return they earned.
