Main interview topics: Board of Directors' operations, composition, roles and functions of the Board of Directors, content of Board of Directors deliberations, support for directors, operation of the Audit and Supervisory Committee, operation of the Nomination and Compensation Committee, and gathering opinions on discussion topics related to corporate governance. -

Executive compensation
Executive compensation determination policy
The compensation for our directors who are not audit and supervisory committee members (excluding External Director) is determined based on a comprehensive consideration of past payment records and company performance, and consists of fixed compensation, performance-linked compensation, and non-monetary compensation. External Director(excluding directors who are audit and supervisory committee members) receive only fixed compensation.
The compensation structure is such that as one's position rises, the proportion of fixed compensation (basic salary) decreases, while the proportion of performance-linked compensation (bonuses) and non-monetary compensation (stock-based compensation) increases. Fixed compensation is paid monthly, while bonuses and stock-based compensation are paid once a year, except for External Director.
Furthermore, starting with executive compensation for the fiscal year ending March 2027, we have revised the evaluation indicators and composition ratios for bonuses and stock-based compensation. Bonuses will reflect individual performance according to position, in addition to company performance, and stock-based compensation will be calculated based on stock price indicators during the medium-term management plan period and the achievement rate of targets in the medium-term management plan.
The decision-making policy is determined by the Board of Directors after consulting with the Nomination and Compensation Committee, which is comprised of a majority of External Director , and receiving its recommendations. Individual compensation amounts are calculated by the President and Representative Director , who is delegated authority by the Board of Directors , after the Committee has considered various factors, including consistency with the decision-making policy, and are therefore judged to be in line with the policy.
Furthermore, the fixed compensation for directors who are audit and supervisory committee members is determined through discussions among the audit and supervisory committee members, and bonuses and stock-based compensation are not paid.
About the Clawback System
We have a system in place (clawback system) that allows the Board of Directors to request the return of all or part of the bonus already paid if a serious violation of laws or regulations occurs after the bonus has been paid.
In a restricted stock compensation plan, if the Board of Directors determines that a recipient of restricted stock has committed a misconduct as defined in the restricted stock allocation agreement, it includes a clause (MARS clause) that allows the Board to acquire all of the granted shares without compensation.
