Mitsubishi Materials Books ¥21 Billion Impairment and Recapitalizes Onahama Smelter

Mitsubishi Materials ( (JP:5711) ) has issued an announcement.

Mitsubishi Materials will book an impairment loss of ¥21 billion in the fourth quarter of the year ending March 2026, tied mainly to fixed assets at its Onahama Smelter & Refinery in Fukushima. The move follows a strategic decision to suspend copper concentrate processing and related smelting facilities at Onahama by around March 2027, after years of margin pressure from tougher overseas competition and worsening copper concentrate terms.

The company will streamline E-scrap and shredder-residue processing by suspending intake or shifting volumes to other group sites, while keeping key downstream operations such as the electrolytic plant, PGM recycling plant, and casting plant running. To shore up Onahama Smelting and Refining’s balance sheet and enable structural reforms, Mitsubishi Materials will convert up to ¥23 billion of loans into equity by June 30, 2026, increasing the unit’s capital to as much as ¥29.9 billion and making it a specified subsidiary fully controlled by the parent.

The most recent analyst rating on (JP:5711) stock is a Hold with a Yen5088.00 price target. To see the full list of analyst forecasts on Mitsubishi Materials stock, see the JP:5711 Stock Forecast page.
