5. Other matters for investment reference: The per-share issue price in this notice is the round-1 issue price; the final issue price will be announced on October 13, 2026 per the formula below.

1) The round-1 issue price is determined using, as the reference share price, the lower of (i) the average of the 1-month volume-weighted average price, the 1-week volume-weighted average price, and the closing price on the base date, each calculated on KOSDAQ, using the third trading day before the new share allotment record date as the base date, and (ii) the closing price on the base date; a 20% discount is then applied per the formula below to determine the issue price (round-1 issue price). Amounts below the quotation unit are rounded up to the nearest quotation unit, and if the resulting price is at or below par value, par value is used as the issue price. * Round-1 issue price = [Reference share price x (1 - discount rate)] / [1 + (capital increase ratio x discount rate)]

2) The round-2 issue price is determined using, as the reference share price, the lower of (i) the average of the 1-week volume-weighted average price and the closing price on the base date, each calculated on KOSDAQ, using the third trading day before the existing shareholders' subscription date as the base date, and (ii) the closing price on the base date; a 20% discount is then applied per the formula below to determine the issue price (round-2 issue price). Amounts below the quotation unit are rounded up to the nearest quotation unit, and if the resulting price is at or below par value, par value is used as the issue price. * Round-2 issue price = Reference share price x (1 - discount rate)

3) The final issue price is the lower of the round-1 and round-2 issue prices. However, under Article 165-6 of the Financial Investment Services and Capital Markets Act and Article 5-15-2 of the Regulation on Issuance and Disclosure of Securities, if the lower of the round-1 and round-2 issue prices is lower than the price calculated by applying a 40% discount to the volume-weighted average price from the 3rd to the 5th trading day before the existing shareholders' subscription date (used as the reference share price), the price calculated by applying a 40% (as stated in the filing)

The general public offering issue price will be the same as the final issue price applied to the employee stock ownership association's and existing shareholders' subscriptions.
