(1) Refers to the actual date on which treasury shares were transferred as a result of the exercise of stock
options. In accordance with Korean disclosure regulations, the period of disposal set forth in the Initial Report covers the period from the first date on which treasury shares were delivered upon exercise of stock options (granted pursuant to a
resolution of the same general meeting of shareholders or the board of directors) until the end of the exercisable period.

(2) Based on the market closing price on the date of the disposal.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3. Discrepancy with the Initial Report

The actual number of disposed shares was 14,621 common shares, compared to 71,726 common shares that were estimated to be subject to disposal as set forth in the Initial Report.

This report concerns the disclosure of disposal of treasury shares due to the exercise of stock options granted at the annual general meeting of shareholders held in 2021 (the "2021 Annual General Meeting of Shareholders"). In accordance with Article 5-9 of the Regulation on Securities Issuance and Disclosure, the number of treasury shares to be disposed of includes all stock options granted at the 2021 Annual General Meeting of Shareholders, excluding those that have expired.

As all stock options exercised were settled using the "compensation in treasury shares for the difference in price" method, the Company transferred treasury shares equivalent in value to the difference between the exercise price and the closing market price on the exercise date (after deducting applicable withholding amounts including taxes).

As a result, a discrepancy arose between the number of shares estimated to be subject to disposal as set forth in the Initial Report and the actual number of disposed shares.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;4. Treasury Shares Held after the Disposal (as of March 27, 2026)
