Carving out JX Metals: an oil refiner lists its semiconductor materials arm (2025)

What the carve-out meant, coming from an oil refiner

The heart of this decision lies in using the stock market to project outward a valuation for a semiconductor-materials business that had been buried inside an oil refiner’s group. JX Metals holds 60% of the world market in sputtering targets, and yet it sat within the same consolidated accounts as the refining and marketing of oil. Carving it out by selling a majority of the shares and taking it out of consolidation gives each business the capital structure and the speed of decision-making that suits it, and it was at the same time a step in the portfolio reform by which ENEOS is shifting its composition away from dependence on oil and toward materials.

Selling a majority is not, however, letting go of control altogether. After the listing ENEOS retains 42.38% of the voting rights, and the relationship of parent and listed subsidiary is not dissolved. In semiconductor materials, where the waves of demand run large, a first trade only slightly above the offer price mixed expectation of growth with wariness of cyclical risk. Even so, a listing of extraordinary size — larger than Tokyo Metro, and the biggest in the six years since SoftBank — offered one answer to the oil refiner’s question of how to show the value of resources and materials to the capital market.
