Decision
On March 31, 2026, Mitsubishi Gas Chemical decided to discontinue polycarbonate production at its Kashima Plant, with operations scheduled to end in March 2028.
Reason
The polycarbonate business has suffered weak profitability and poor capital efficiency due to a market-price slump caused by oversupply; it was designated a business requiring intensive management under the MTMP 2026 and has been subject to structural reforms.
Plant details
The affected facility is the polycarbonate production unit within the Kashima Plant with a capacity of 120,000 tonnes per year; Iupizeta EP optical resin from the Optical Materials Division is excluded from this discontinuation.
Supply and workforce
Following closure, domestic polycarbonate supply will be supported by the Group’s overseas facilities, and the company says it will prioritize continued employment for employees currently engaged at the plant.
Financial outlook
MGC is assessing the decision’s impact on consolidated and non‑consolidated results for the fiscal year ending March 31, 2026 and will disclose any matters that require announcement.
