Mitsu Chem Plast Limited has announced the closure of its trading window for Insiders, Designated Persons, and their Immediate Relatives. This closure will commence from January 1, 2026, and will remain in effect until 48 hours after the company declares its financial results for the quarter ending December 31, 2025. This measure is implemented to prevent insider trading and ensure fair disclosure of upcoming earnings information, a common practice ahead of quarterly financial announcements.
