1. Category: confirmed issue price 2. Issue price per share: common shares (KRW) 6,580; special class shares 3. Other matters for reference in investment decisions Note: the per-share issue price in this notice is the confirmed issue price.

Method of determining the issue price (1) First issue price: using the business day three trading days before the record date for allotment of new shares (June 9, 2026), i.e., June 4, 2026, as the reference date, the lower of the closing price and the arithmetic mean of the one-month and one-week volume-weighted average prices and the closing price is the first reference price; a 20% discount is applied, with the rights-offering ratio calculated as rights-offering shares divided by total issued shares. Amounts below the quotation unit are rounded up; if at or below par value (KRW 1,000), par value is used. * First issue price = [reference price x (1 - discount rate)] / [1 + (rights-offering ratio x discount rate)] (2) Second issue price: using the business day three trading days before the existing-shareholder subscription date (July 13, 2026), i.e., July 8, 2026, as the reference date, the lower of the closing price and the arithmetic mean of the one-week volume-weighted average price and the closing price is the second reference price, with a 20% discount applied. Amounts below the quotation unit are rounded up; if at or below par value (KRW 1,000), par value is used. * Second issue price = reference price x (1 - discount rate) (3) Confirmed issue price: the lower of the first and second issue prices. However, under Financial Investment Services and Capital Markets Act Article 165-6 and Regulation on Issuance and Disclosure of Securities Article 5-15-2, if that lower price is below the price obtained by applying a 40% discount to the volume-weighted average price over the third to fifth trading days before the subscription date, that 40%-discounted price becomes the confirmed issue price. Amounts below the quotation unit are rounded up, and if the confirmed issue price is at or below par value (KRW 1,000) (the source text is incomplete here, as stated in the filing). The general-offering issue price equals the confirmed issue price applied to the employee stock ownership association and existing-shareholder subscriptions.
