Regarding Partial Revision of the Basic Policy on Internal Control System

The Company regularly reviews the Basic Policy on Internal Control System. We hereby notify you that necessary revisions were made and resolved at the meeting of the Board of Directors held on June 25, 2025 as follows, while the basic approach remains unchanged.

The revised parts are indicated with underlines.

  1. Basic Approach to Corporate Governance

    The Company believes that excellent governance means operating businesses that enhance the corporate value of the Company for all stakeholders, through fair and open businesses managed from a long-term perspective as a going concern that balances both environmental and social considerations, while aiming to maximize shareholder value. Based on this principle, we strive to establish healthy and functional corporate governance, and to build a corporate ethics system that ensures the transparency and soundness of corporate activities.

  2. Overview of Corporate Government System

    The Company has adopted the structure of a company with Audit & Supervisory Board Members, aiming at maintaining and improving its corporate governance system by strengthening the functions of the Board of Directors while utilizing the supervisory function of Audit & Supervisory Board Members.

    The Company has also adopted an executive officer system. This system enhances and revitalizes the functions of the Board of Directors, which is the highest level of the Company's decision-making bodies and is in charge of supervising the Company's management, while improving and accelerating the execution of business by Executive Officers. Meanwhile, the Company has appointed Outside Directors and Outside Audit & Supervisory Board Members to reinforce the supervising and monitoring functions of its management.

    Directors are appointed to terms of one year in order to ensure strong management practices by clarifying their management accountability and to flexibly develop a management system that can respond quickly to changes in

    the operating environment.



    Board of Directors

    The Board of Directors consists of seven Directors (including four Outside Directors). The Board of Directors holds a regular meeting once a month, in principle, and an extraordinary meeting as necessary to deliberate, approve, and decide on matters provided by laws and regulations, matters related to management plans, and other important matters related to the organization, systems, personnel affairs, financial affairs, facilities, and labor agreements, as well as supervises the execution of business.

    In addition, the Nomination and Remuneration Committee has been established as a voluntary advisory body to the Board of Directors to strengthen the supervisory function of the Board of Directors by ensuring objectivity, fairness, and transparency in the procedures for nominating Directors and determining their remuneration.

    Corporate Strategy Council

    The Corporate Strategy Council is chaired by the President and consists of General Managers of Headquarters and Divisions, etc.

    The Corporate Strategy Council holds a meeting once a month, in principle, and an extraordinary meeting as necessary to discuss and decide on management issues that span the entire company or multiple departments, issues related to sustainability, and the status of execution of matters decided by the Corporate Strategy Council.

    Executive Committee

    The Executive Committee is chaired by the President and consists of Executive Officers, Full-Time Audit and Supervisory Board Members, and other persons designated by the President.

    The Executive Committee holds a meeting once a month, in principle, and an extraordinary meeting as necessary

    to discuss and decide on matters related to business execution to be brought before the Board of Directors, matters related to the execution of decisions made by the Board of Directors or the Corporate Strategy Council, matters related to business execution by each department based on management plans, and important matters related to sales, technology, and production.

    Audit & Supervisory Board

    The Audit & Supervisory Board consists of four members (including two Outside Audit & Supervisory Board Members).

    The Audit & Supervisory Board decides audit policies, receives reports on audits from each Audit & Supervisory Board Member, and receives reports on audits from the Accounting Auditors as needed. The Audit & Supervisory Board works closely with Accounting Auditors, the Internal Auditing Office, and Audit & Supervisory Board Members of subsidiaries to keep track of the operational status of internal control.

    Audit & Supervisory Board Members attend the Board of Directors' meetings and other important meetings related to management to check the soundness of management and transparency of the decision-making process. The Audit & Supervisory Board Members also primarily verify the legality, appropriateness and validity of Directors' execution of duties through reports from Directors and the review of critical corporate authorization documents. Full-Time Audit & Supervisory Board Members attend Executive Committee meetings and report the details thereof at Audit & Supervisory Board meetings.

  3. Enhancement of the Internal Control System and Risk Management

    As a company that is engaged in businesses deeply linked to public needs, public interests and community safety, we believe that it is essential to have a strong sense of responsibility, integrity and ethics, while complying with laws, regulations and community standards. Based on this belief, we have created and are operating an internal control system for the Company, including its subsidiaries.

    Compliance

    The Company has appointed the President as the chief administrator of compliance (Compliance Officer).

    The Company and its subsidiaries strive to fully comply with laws, regulations, rules, social and corporate standards of ethics and the Code of Conduct.

    Risk Management

    The Company has appointed the President as the chief administrator of risk management (Risk Management Officer).

    To strengthen risk management, the Company and its subsidiaries have established a risk management system based on the "Risk Management Regulations."

    The Audit & Supervisory Board evaluates the status of development and operation of the internal control system, as well as assesses risks related to the business execution of the Company and its subsidiaries and requests improvements and makes proposals based on audits regarding the effectiveness, efficiency and legality of business operations.
