Recognizing the importance of management as a socially- responsible company, the MIRAIT ONE Corporation has established organizational structures and systems to ensure transparency and fairness in decision-making. Building trusting relationships with all of our stakeholders including shareholders is positioned as the most important aspect of management.

We recognize that achieving effective corporate governance is essential for building trust with stakeholders. We are committed to enhancing the effectiveness of our corporate governance through the following measures:

We are a company with an Audit and Supervisory Committee, overseen by a board of directors, an audit and supervisory committee, and accounting auditors. We have set up a system for reciprocal cooperation where the Audit and Supervisory Committee together with an internal audit section and accounting auditors each perform independent inspections.

Also, we are working to further improve corporate value by strengthening the governance and the internal audit structure based on the policy of three-lines of defense, strengthening corporate governance through a close liaison between the Audit and Supervisory Committee and the internal audit sec-Dition, improving the soundness and transparency of management, and making quick decisions.

In the process of nominating candidates for the Board of Directors, the MIRAIT ONE Corporation selects a wide variety of candidates from both inside and outside the company, consults with the Nomination and Compensation Committee, which is chaired by an independent outside director, and determines the candidates who have excellent personalities, superior insight and high managerial capabilities, at the Board of Directors’ meetings based on the responses from the Committee.

* The rationale for selection of each director is outlined in the notice of general meeting of shareholders.

For outside directors, we appoint individuals who have abundant experience and knowledge across different fields and can carry out their roles and duties with a specialized and objective viewpoint by providing guidance and managerial supervision from the perspective of enhancing the medium- to long-term corporate value of the company. For the independent outside directors who are members of Audit and Supervisory Committee, we appoint those who have abundant experience and knowledge across different fields, and can with independent and objective views properly monitor the board of directors’ managerial decisions, execution of duties, and their observance of laws and ordinances, enhancing transparency of the board and serving greater corporate value.

Outside directors attend meetings, including Board of Dicomrectors meetings, to understand the Group’s management issues. In addition, they offer their opinions from their respective professional and objective viewpoints as needed, and strive to ensure transparency and efficiency in management by exchanging views with other directors.

* The criteria for determining the independence of outside directors of the Company and the status of their activities are provided in the “Corporate Governance Report” and other documents.

As a business holding company that oversees various business fields, the Company ensures that the composition of the Board of Directors is well-balanced by appointing individuals with a wealth of experience and superior knowledge in various specialized fields, such as business strategy, international strategy, finance, and personnel affairs.

In addition, the Company aims to ensure transparency and enhance corporate value by having individuals with many years of practical experience in corporate management, experts in corporate legal affairs and finance, and academic experts join the Board of Directors as outside directors and provide an outside perspective.

The Company has appointed five women executive officers: two directors who are not members of Audit and Supervisory Committee, two directors who is a member of Audit and Supervisory Committee and one executive officer.

The expertise and experience (skills) required of directors, as well as their details, are as shown in the above “Skills Matrix for Directors” and “Definition of the Primary Areas of Experience and Expertise (Skills) of Directors.”

In accordance with the Regulations of the Board of Directors, Board of Directors meetings are held once a month and as needed, and 20 meetings were held during FY 2024. The Board of Directors deliberates on all matters required under the internal regulations to be submitted to it, and actively exchange opinions on each matter, as well as receive quarterly reports on the status of execution of duties by each director.

Also, in light of the Corporate Governance Code, the “Nomination and Compensation Committee,” a voluntary advisory committee, was established under the Board of Directors to enhance the objectivity of nomination and com pensation. The Committee met seven times during FY 2024.

Independent outside directors hold regular meetings with representative directors to strengthen the monitoring function for the execution of duties by directors.

In addition to inspecting important decision-making documents,Audit and Supervisory Committee Members attend significant meetings including Group Executive Committee meetings to gain an understanding of the company’s important decision-making process and the status of business execution.

In addition, Audit and Supervisory Committee Members, representative directors, the Accounting Auditor, and others communicate with each other and exchange opinions to ensure that the audits by Audit and Supervisory Committee Members are conducted effectively.

The Company has established the Audit and Supervisory Committee Office with full-time staff to assist the Audit and Supervisory Committee in its duties, and three individuals have been assigned to this office.

At the Board of Directors meetings, we check the execution of duties by directors, including the state of compliance with laws and regulations, the state of risk management and information sharing, and the speed with which issues are resolved, and we also strive to ensure the effectiveness of the Board of Directors as a whole by holding meetings between representative directors and outside directors.

In addition, once a year, all directors are subject to a self-assessment of the effectiveness of the Board of Directors with the aim of improving the functioning of the Board of Directors as a whole and sharing awareness of the direction in which our corporate governance is headed.

More specifically, the self-assessment is conducted through an anonymous questionnaire to ensure that candid opinions are heard, and the questionnaire consists of major assessment items asking about the structure, operational status, responsibility and functions of the Board of Directors and the state of the Board of Directors as seen from outside directors. As for collecting responses, they are collected by an external law office with a duty of confidentiality, and they are analyzed by a third-party organization. Based on the results of this analysis, our Board of Directors has verified and evaluated the current situation and obtained favorable results, and continues to discuss issues related to the Board of Directors.

The Company has established a systematic and regular series of executive seminars for directors and executive officers of the MIRAIT ONE Group. These seminars serve multiple purposes, including: (1) instilling and strengthening basic management skills appropriate for a prime market company; (2) providing opportunities to develop a comprehensive understanding of the market, technology and global trends including global conditions; and (3) aligning the direction of the directors and executives.

In addition, outside directors and others are provided with opportunities including inspections of business establishments of operating companies and construction sites, as appropriate, so that they can deepen their understanding of our business content and current conditions.

Regarding succession planning and development for the CEO and other senior executive positions, from the perspective of ensuring transparency and fairness in company decision-making and enhancing corporate governance more effectively, we formulated a “Succession Plan for Directors (including Representative Directors)” at the Board of Directors meeting held on April 26, 2024.

This plan is being appropriately implemented in line with our management philosophy and business strategy. For the appointment of the CEO, the Nomination and Compensation Committee, chaired by an independent outside director, is consulted, and the Board of Directors votes on the appoint-ment based on the report of the Nomination and Compensation Committee.

With regard to the compensation of directors (excluding the directors who are Audit and Supervisory Committee Members. The same applies below), the total amount (limit) is set by the General Meetings of Shareholders after approval by the Board of Directors, and each director receives compensation in accordance with their roles and responsibilities.

Also, with regard to the policy for deciding the compensation of each director, for the purpose of enhancing objectivity and transparency, the “Nomination and Compensation Committee” (chaired by an independent outside director), which is an advisory body to the Board of Directors and consists of a majority of independent outside directors, reports the results of its deliberations to the Board of Directors, which then makes decisions based on the report.

Outside directors, who are responsible for supervisory functions, are paid only monthly basic compensation in light of their duties.

* Details of compensation for executive officers are provided in the “Securities Report.”

The Company has introduced the “Board Benefit Trust,” a performance-linked stock compensation system, to clarify the link between the compensation of executive officers and the Company’s business performance and stock value, and to increase awareness of their contributions to the Company’s performance and value over the medium to long term.

As for the indicators for performance-linked compensation, the Company has chosen the degree of achievement in areas such as the “consolidated operating income,” “ROE,” and “ESG indices.” These metrics were selected for their ease of understanding and are designed to raise awareness of one’s contribution to improving the Group’s consolidated performance and corporate value. A benchmark was established by allocating 30% of the monthly compensation for a period of three months in accordance with the “Internal regulations on issuing shares to executives.” Under the point system, the number of points is calculated by multiplying the performance-linked coefficient determined by the level of achievement of the Company’s metrics.Upon retirement, one share is granted for each point earned.

Also, in FY 2022, the Company introduced the “GHG reduction target” into the set of indexes for performance-linked compensation as a consolidated ESG index to raise awareness of ESG initiatives among management personnel.

For FY 2024, it has been resolved at the Board of Directors meeting on June 25, 2024 that the decision on the amount of basic compensation for each director and the amount of bonuses based on the business performance of each fiscal year would be left to Representative Director, President NAKAYAMA Toshiki, assuming that the Nomination and Compensation Committee would be consulted within the range of the total amount approved at the General Meeting of Shareholders. The reason for delegating these authorities is that the Representative Director, President is considered to be the most suitable person to evaluate the execution of duties by each director while having a bird’s eye view of the company’s overall business.

This information is not provided because no executive officer received a total of 100 million yen or more in consolidated compensation, etc.

We require that competitive transactions and conflict-of-interest transactions conducted by directors be deliberated and approved by the Board of Directors, and that the status of such transactions be reported to the Board of Directors on a regular basis.

We require executive officers to submit a “Related Party Confirmation Statement” to ascertain whether there are any transactions with related parties, such as themselves, their close relatives, organizations they represent, and organizations in which they hold majority voting rights.

With regard to transactions with major shareholders, in accordance with internal regulations, the person with decision-making authority is required to confirm the appropriateness of such transactions to ensure that they do not harm the Company or the common interests of shareholders, and report particularly important transactions to the Board of Directors.

Shares held for other purposes are classified as investment shares for pure investment purposes.

A. Holding policy
Our group holds shares of its business partners when it believes that holding such shares will enhance the Group’s corporate value and benefit its shareholders. After reviewing the purpose of holding shares and the status of transactions, etc., if the holding of such shares is deemed to be of little significance through quantitative and qualitative verification, we will gradually reduce the holdings through divestment, etc.

B. Methods of verifying the rationality of shareholding
The Company conducts quantitative and qualitative review of strategic shareholdings in terms of medium- to long-term economic rationality and future prospects based on return and risk, etc.

C. Details of review by the Board of Directors, etc. as to whether or not to hold individual issues
With regard to strategic shareholdings retained by the Group, the Company conducts a review of the purpose of holding such shares, the status of transactions, etc., and determines whether or not to continue holding such shares by reviewing each individual issue quantitatively and qualitatively once a year at a meeting of the Board of Directors, in terms of whether the returns and risks associated with the holdings are commensurate with the cost of capital, the purpose of the holdings, future business trends, etc.

We are divesting shares for which, as a result of the verification, we believe there is little significance in holding, taking into consideration the share price and other factors. In addition, we will manage the status of strategic shareholdings and their reduction across the entire Group through annual verification. Based on the above policy, etc., we divested 9 issues in FY 2024.

On May 30, 2025, (26 days prior to the General Meeting of Shareholders), the Company initiated electronic delivery measures on the Tokyo Stock Exchange and the Company’s website (the legal date was June 4). This was done to ensure that shareholders had sufficient time and access to information to exercise their voting rights.
