12. Other Matters Relating to an Investment Decision

- Items 1, 2 and 3 above are based on the closing price of the Company's shares on April 23, 2025, the day before the date of the resolution by the board of directors.

- The actual number, price and aggregate value of the treasury shares to be disposed may change as of the date of disposal.

------

Regarding Item 5 above, the purpose of the disposal is to grant 4,860 treasury shares to five independent non-executive directors through the Company's compensation program for its independent non-executive directors, which is tied to the Company's enterprise value and under which the Company grants treasury shares as a portion of the independent non-executive directors' compensation. The number of treasury shares granted to each independent non-executive director varies depending on factors including the role and responsibility of each independent non-executive director. In addition, the long-term incentive stock-based compensation for executives is intended to deliver an aggregate of 49,152 shares to 128 recipients pursuant to long-term incentive compensation agreements. The number of shares to be delivered to each individual represents the number of shares remaining after taxes and other applicable deductions, following the final determination of the settlement quantity. <br>

- This decision to dispose of treasury shares is expected to be carried out within the scope of the "the Plan for Holding and Disposal of Treasury Shares" approved at the 42nd Annual General Meeting of Shareholders held on March 26, 2026.
