Notice on Formulation of Recurrence Prevention Measures

Overview of Recurrence Prevention Measures

This report states that, in response to inappropriate accounting practices at consolidated subsidiary M Co., we will promote recurrence prevention measures in five key areas. We will focus on strengthening new business management and preventing concentration of authority, establishing subsidiary management frameworks, reinforcing parent company supervision of subsidiaries, strengthening related-party transaction management, and enhancing acquisition due diligence. We will implement the establishment and review of related regulations, organizational strengthening, and enhancement of audit functions in a phased manner.

Progress Management and Verification of Effectiveness

Overall progress of the recurrence prevention measures will be overseen by the Management Division acting as the secretariat and reported to the monthly Board of Directors meetings. If delays or issues arise, they will be addressed through consultation with the responsible departments and the Audit and Supervisory Committee. The Internal Audit Office will monitor effectiveness and revise operations as necessary. By the end of November 2026, we plan to increase the staff of the Internal Audit Office and advance the preparation of group-wide internal regulation templates and training.
