Corporate governance Report (Mar. 31, 2025)

Overview of the Corporate governance Structure

(The information above is current as of March 31st, 2025, unless otherwise stated.)

To ensure efficient corporate management and highly effective supervision based on its corporate mission, the Company has adopted the structure of a Company with Audit and supervisory board Members, whereby Audit and supervisory board Members 24 audit the business execution of Directors, who are well versed in their fields. In addition, the Company strives to further increase the agility and efficiency of its management by introducing an Executive Officer System aimed at further strengthening its business operation system in order to respond accurately and quickly to a rapidly changing management environment and the expansion of its business activities.

The Company frequently engages in important negotiations with national governments and international energy companies. This necessarily requires internal Directors and Executive officers that have knowledge, expertise and international experience relating to the Company’s business and both a sound knowledge of the Company and their particular fields of expertise. Internal Directors in principle hold concurrent position as Executive officers. By adopting this organizational structure, the Company’s Board of Directors is better placed to make decisions on the execution of business in an efficient manner. At the same time, this structure helps to ensure the effective supervision of management.
The Company has appointed five of its ten members of the Board of Directors from Outside the Company to enhance the transparency of management and strengthen the effective supervisory function of the Board of Directors. This also aims to utilize for management objective perspectives which are different from the ones of insiders: those Directors from outside the Company are, from their independent standpoint, expected to provide advice based on their own knowledge and experience, monitor the management and conflict of interest transactions, and to appropriately represent the views of stakeholders to the Board of Directors. The Company has selected Outside Directors from external persons who have extensive experience and wide-ranging insight as corporate managers, academics, or other specialists in the resource/energy industry, or in fields of finance or legal affairs, etc.

Furthermore, four of the five Audit and supervisory board Members are Outside Audit and supervisory board Members. In addition, in order to strengthen the audit function by ensuring independence of Audit and supervisory board Members and efficiency of audits, an Audit & Supervisory Board has been established pursuant to laws and regulations. Further efforts of the Company include the placement of employees in Audit and supervisory board Members’ Office as an organization dedicated to assist operations by Audit and supervisory board Members, and efforts in strengthening the coordination between the internal audit department(Audit Unit), Outside Directors, and accounting auditors.

The Company has adopted an Audit and supervisory board Members system.

The Audit and supervisory board Members possess considerable knowledge and experience in the Company’s business, as well as in fields related to finance, accounting, legal affairs and others, and leverage these skills in performing auditing activities for the Company. The Company has set up the Audit and supervisory board Members’ Office as an independent organization from the business execution departments and shall deploy four dedicated employees possessing the necessary and appropriate knowledge and ability to assist the Audit and supervisory board Members with auditing duties in order to enhance the effectiveness of audits by Audit and supervisory board Members.

Activities of the Audit & Supervisory Board: In principle, the Audit & Supervisory Board meeting is held on a monthly basis on the same date as the Board of Directors meeting. Additionally, the Audit & Supervisory Board has ad hoc meetings as necessary. The Audit & Supervisory Board resolves statutory matters including audit plans and receives reports on the execution of duties from the internal audit department (Audit Unit) and the accounting auditor, Ernst & Young ShinNihon LLC, and requests clarifications if necessary. Further, Audit and supervisory board Members share information they gather through their individual auditing activities and have discussions as necessary.

Regular meetings with representative Directors are held for the purpose of exchanging opinions and monitoring the implementation of management policies as well as the development and operation of internal control systems. Further, meetings with Directors are held regularly for the purpose of conducting hearings on the status of business executions with Directors in charge of the Company’s respective business divisions. Additionally, full-time Audit and supervisory board Members attend regular and ad hoc Executive Committee meeting and ad hoc Compliance Committee meetings, gather information through reviewing internal approval documents, and if necessary, request clarifications from business divisions.

4. Internal Audit

The Audit Unit was established under the direct supervision of the President & CEO (with 13 dedicated staff as of March 27, 2024) as an internal audit department independent of the divisions involved in the execution of the Company’s business. The Audit Unit verifies the design and operational status of internal controls across all management activities of our company and its group companies through internal audits, identifying areas for improvement. These areas for improvement are followed up until their correction is completed, and significant matters are shared with all departments within the company, contributing to the maintenance and enhancement of the effectiveness of internal control. The Audit Unit follows up these areas for improvement until their correction is completed, and shares the significant matters among them with all departments of the company.
In developing annual audit plans, the Audit Unit discusses and exchanges opinions with the Audit and supervisory board Members, and after obtaining the President & CEO's approval, makes reports to the Board of Directors. Additionally, the results of the internal audits are reported at meetings of the Board of Directors / Audit & Supervisory Board and to the President & CEO, full-time Audit and supervisory board Members, and are shared with accounting auditors.
To ensure the expertise of those involved in internal audits, the Audit Unit encourages the acquisition of qualifications related to internal audits and active participation in external training courses, and it has several Certified Internal Auditors (CIA).

According to the stipulations of the Articles of Incorporation, INPEX issues a Class A Stock to the Minister of Economy, Trade and Industry. Unless otherwise provided by laws or ordinances, the Class A Stock does not possess voting rights at shareholders’ meetings. However, it is possible for the holder of the Class A Stock to exercise veto rights for certain major corporate decisions. We believe the holding of Class A Stock by the Minister of Economy, Trade and Industry will help prevent any incidence of unusual management, allow INPEX to stably supply energy as a core company for Japan’s oil & gas E&P and ensure that the Company does not incur any negative impact from a speculative acquisition or an attempt at management control through foreign capital. On this basis, INPEX’s role is assured. Furthermore, we expect positive results in terms of external negotiation and credits as a national flagship company efficiently contributing to the stable supply of energy in Japan.
