Principle 1.4 Cross-Shareholdings
(1) Policy on cross-shareholdings
Regarding cross-shareholdings, the Company's policy is to hold shares that it believes will contribute to enhancing corporate value for the Group over the medium to long term. Based on its policy of selectively holding the minimum cross-shareholdings necessary, the Company considers the rationale for holding a specific stock, including a comprehensive assessment of factors such as its business strategy and relationships.
(2) Cross-shareholding verification details
Based on the policy above, the Company verifies the appropriateness of continuing to hold certain stocks once a year at a meeting of the Board of Directors. The Board of Directors reviews the holdings in determining whether to continue to hold the shares through both a quantitative approach, such as a review of the amount of dividends received and projected dividends or a comparison of the Company's cost of capital and the target company's ROE, and a qualitative approach, through an assessment from a business strategy perspective. The shares to be held, the number of shares, the purpose and effect of shareholdings and other factors are disclosed in the Company's Annual Securities Report.
(3) Criteria for exercising cross-shareholding voting rights
The policy on exercising voting rights related to strategically held shares is based on the decision of whether exercising such rights will enhance the medium- to long-term corporate value of the Company and the entity whose shares are held.
Principle 1.7 Related Party Transactions
Transactions with related parties, such as the Company's directors or major shareholders, require discussion and a resolution from the Board of Directors. Directors with a conflict of interest are prohibited from exercising their voting rights on the matter. Moreover, all directors, corporate auditors and executive officers are required to provide written confirmation of the presence or absence of transactions with related parties once a year.
Supplementary Principle 2.4.1 Ensuring Diversity in the Promotion of Key Personnel
The Group has identified “maximizing the value of human capital” at the beginning of our materiality. Human capital is the most important form of management capital in corporate activities and serves as the foundation for all other forms. “Respect for the Individual” is established as the primary pillar of the Management Principles. The Company’s philosophy is to be a corporation that respects the rights of every employee, allows individuals to pursue a meaningful and cultural life and a worthwhile life, trusts in the aspirations of each individual, supports independent activities, prepares an environment where abilities can be demonstrated to the fullest through work, and ensures employees are rewarded for their abilities and performance. Based on this, the Company maintains various policies and systems regarding human capital.
<Approach to ensuring diversity, measurable goals, and status of progress>
The Group aims to build a work environment where all employees can demonstrate their abilities and play active roles, regardless of gender, nationality, age, or disability. It has set targets for the number of female managers and female directors and is working to ensure a diverse workforce. In addition, it also actively promotes mid-career hires to management positions. As of March 31, 2026, on a non-consolidated basis, 57.8% of management positions were filled by mid-career hires.
(1)Promotion of women to management positions
Regarding the hiring of women, the Company promotes the hiring of female new graduates, and in mid-career hiring, is actively hiring women and promoting them to management positions. The target for the number of female managers is five on a non-consolidated basis by the fiscal year ending March 31, 2028, and as of March 31, 2026, there were four. Regarding the promotion of women to management positions, the proportion of potential candidates among all employees is currently low at this time; therefore, we will broaden our pool by hiring and enhancing support for career development.
(2)Promotion of foreign nationals to management positions
To secure human resources who share the Group’s Management Principles and have the abilities required to realize its business strategy, the Group hires both new graduates and mid-career candidates, making no distinction between Japanese and foreign nationals, to build a diverse organization. In addition, the Company traditionally promotes employees to management positions based on merit, regardless of nationality or other factors. However, as of March 31, 2026, the ratio of foreign employees was 1.2% (eight employees) of the Company on a non-consolidated basis, most of whom were hired as new graduates. Therefore, the Company will prioritize hiring foreign employees first and will consider target figures for management positions in the future.
(3)Promotion of mid-career hires to management positions
To secure human resources who share the Group’s Management Principles and possess the abilities required to realize its business strategy, in addition to regular hiring targeting new graduates, the Group aims to build a diverse organization by actively hiring mid-career candidates with varied experience, skills, and qualifications, who are expected to provide immediate results. Note that the Group has conventionally promoted new graduates and mid-career hires without distinction to management positions, based on merit. Because the ratio of mid-career hires and the number of mid-career hires in management positions are sufficient to meet the Company’s standards, we have set no specific targets. As of March 31, 2026, on a non-consolidated basis, the status of the promotion of mid-career hires to management and higher positions at the Company is as follows:
・Percentage of mid-career hires in management positions: 57.8%
・Percentage of mid-career hires in executive officer positions (excluding those concurrently serving as directors): 80.0%
<Summary and status of human resource development and internal environment improvement policies to ensure diversity>
(1)Human resource development policy
Developing human resources capable of realizing the Group’s Management Principles is a basic policy of the Group. The Group conducts initiatives for strategic development, which are divided into the following three phases in line with its human resource development policy.
・Phase I: Education and training
- Thorough adherence to the basics of the “ideal human resources” sought by the Company
・Phase II: Practical application <recognized internally for excellence>
-Through practical work aimed mainly at improving their competencies and establishing their expertise, the Group will support individual initiatives and encourage growth through individual effort. Additionally, we will strategically develop future executive candidates.
・Phase III: Demonstration of expertise <recognized for excellence outside of the Company>
-While leveraging the abilities and experience they have cultivated to date, such as in management, specialized skills and techniques, undertake initiatives to ensure that employees are multi-skilled. Furthermore, employees will contribute to division operations and the development of younger employees as personnel responsible for developing others.
(2)Internal environment improvement policy
The Group is working to establish work environments in which its diverse workforce can demonstrate their abilities, developing into an organization in which each individual can play an active role. Its primary initiatives are as follows:
Human resource system
The Group develops its human resource system under the belief that improving its employees' competencies and motivation will enable its management vision and goals to be achieved. To encourage employees to independently manage their career development and enhance internal human resource mobility, it has established job rotations, self-nomination, and internal job posting systems. Moreover, it is developing various systems to support a variety of work styles that can be used regardless of employment status, such as its childcare and nursing care leave systems. The Group is especially focused on enhancing its support for balancing work and childcare, and is promoting the development of an accommodating work environment through systems for vacation, leaves of absence, and returning to work related to maternity and childcare, as well as shortened working hours, remote working, etc. As a part of promoting the active participation of women in the workplace and reforming work styles, the Group is actively undertaking initiatives to promote the use of its childcare leave system by male employees. In the fiscal year ended March 31, 2026, the percentage of eligible male employees using the childcare leave system was 88.2% on a non-consolidated basis.
Skill development system
Regarding skill development, the Company formulates systematic, medium- to long-term human resource development plans and has a system that enables each employee to effectively and continuously improve and develop the skills required of them. Skill development training includes the following: mandatory level-based training for employees in all positions which enables them to demonstrate the capabilities required for their position; basic training necessary for job performance and career development; and area-of-expertise training aimed at increasing specialization in work activities and the acquisition of specialized skills necessary for career development. Also, given the increasingly sophisticated economic environment and technological standards, and advances in globalization, the Company provides special training programs supporting employees in acquiring MBAs, MOTs and other degrees from universities or other institutions of higher learning in Japan and overseas, as well as training at overseas affiliates and language study through AEI programs at overseas universities to further enhance skills through self-development. The Company also actively provides support for the engineers and operators who contribute to its medium- to long-term growth, in seeking internal accreditation or external certifications.
Implementation of an employee engagement survey
Improving employee engagement is linked to increased innovation and improved productivity, quality, and customer satisfaction. Based on the belief that it contributes to the medium- to long-term enhancement of corporate value, we conduct an employee engagement survey once annually and undertake initiatives to improve employee engagement based on the survey results.
Health management system
The Company views the health of its employees as important management capital and promotes initiatives to enhance their health and safety and health management. Specific initiatives are as follows:
・Understanding employee health conditions and preventing physical and mental health issues through periodic physical exams, stress checks, etc.
・Establishment of a specialized division for promoting health, the Health Promotion Center, and in-depth health consultations and guidance from in-house nurses.
・Establishment of contact points for reporting and consultation on in-house and external harassment, as well as other issues.
・Provision of a remote working environment, among other measures.
Human capital initiative details are also published in the Integrated Report and Annual Securities Report and on the Company website

The Company has both defined-benefit and defined-contribution pension plans. With respect to asset management (including selection of investees, exercise of voting rights, etc.) for the covenant-type defined-benefit pension plan, the Company formulates the basic investment policy, selects asset management institutions that are expected to appropriately fulfill their fiduciary responsibilities, including stewardship activities, and entrusts the management of the assets to these institutions. In addition, the department in charge of the asset management of the Company requests regular reports from the relevant asset management institutions and verifies their investment performance and systems.
Regarding the defined-contribution pension plan, the Company provides eligible officers and employees with educational opportunities related to asset management institutions and investment products as appropriate.

Supplementary Principle 3.1.3 Sustainability Initiatives
<Sustainability initiatives>
The Group positions sustainability initiatives as important for the medium- to long-term enhancement of corporate value and is gradually advancing the development and sophistication of its promotion system.
Specifically, the Sustainability Committee, responsible for formulating Group-wide policies, deliberating, and overseeing important issues, was established on April 1, 2023, to build a promotion system at the management level. In July 2024, the Sustainability Management Office was newly established as a dedicated organization to plan measures, coordinate with each department, manage progress, and enhance information disclosure. Furthermore, in April 2025, four subcommittees—Environmental, Human Resource, Sustainable Procurement, and Human Rights & Ethics—were established to strengthen internal dissemination, evolving into a system that promotes highly effective initiatives. As a result, the Company has developed a system to consistently manage everything from strategy formulation to the execution of measures and improvements, establishing a promotion system that links responses to sustainability issues to the enhancement of corporate value.
Response to climate change
The Group recognizes that addressing climate change is an important management issue, has set the long-term goal of achieving “Net Zero by 2050” and the medium-term goal of “Reducing GHG emissions in FY2030 by 30% versus the FY2022 level,” and is working to achieve it under its Sustainability Committee.

Based on these analyses, the Sustainability Committee plays a central role in promoting initiatives to create opportunities and minimize risks.
