The cancellation will be effected by cancelling treasury shares to be acquired within the limit of distributable profits resolved by the Board of Directors on the same date, in accordance with the proviso to Article 343, Paragraph 1 of the Commercial Act. As such, the total number of issued shares will decrease, but there will be no change to the Company’s capital. For further details relating to the acquisition of treasury shares, please refer to the current report on Form 6-K titled “Decision on Acquisition of Treasury Shares” furnished by the Company on August 19, 2026.

The “Class and Number of Shares to be Cancelled” set forth in Item 1 above was calculated by dividing the “Estimated Aggregate Cancellation Value (Won)” set forth in Item 4 above by the closing price of the Company’s common shares on the day prior to the date of the resolution by the Board of Directors (August 18, 2026: Won 1,662,000). However, the actual number of shares cancelled and the cancellation amount may change depending on movements in the Company’s share price during the treasury share acquisition process, and the exact number of shares will be disclosed through a subsequent disclosure.

The “Total Number of Issued Shares” set forth in Item 2 above refers to the total number of issued shares as of the date immediately prior to the cancellation.

The “Par Value Per Share (Won)” set forth in Item 3 above refers to the face value of the shares.

Regarding the “Scheduled Cancellation Date” set forth in Item 7 above, the Company plans to cancel all shares acquired in a single batch after the completion of the acquisition of treasury shares.
