Other matters for reference in investment decisions This notice discloses the round 1 issue price; the final issue price will be announced on September 1, 2026 under the formula below. Pursuant to Article 5-18 (Determination of Rights Offering Issue Price) of the Regulation on Issuance and Disclosure, etc. of Securities, the discount rate, etc. for shareholder-allotment capital increases has been liberalized and may be freely determined; however, due to concerns about market disruption and existing practice, the price will be determined by applying, in part, the former Article 57 of the Regulation on Issuance and Disclosure, etc. of Listed Securities. (1) Round 1 issue price calculation: using the 3rd trading day before the new-share allotment record date as the base date, the reference price is the lower of (i) the arithmetic mean of the 1-month volume-weighted arithmetic mean price, the 1-week volume-weighted arithmetic mean price, and the base-date volume-weighted arithmetic mean price, calculated retroactively from the base date using the trading value and volume established on the KOSDAQ market for the issuer's shares, and (ii) the base-date volume-weighted arithmetic mean price; the issue price is then calculated under the formula below applying a 25% discount rate. However, if the resulting price is below par value, par value shall be the issue price. (Amounts below the quotation unit are rounded up to the quotation unit.) Round 1 issue price = [reference price x (1 - discount rate)] / [1 + (capital increase ratio x discount rate)] (2) Round 2 issue price: using the 3rd trading day before the existing-shareholder subscription date as the base date, the round 2 reference price is the lower of (i) the arithmetic mean of the 1-week volume-weighted arithmetic mean price and the base-date volume-weighted arithmetic mean price, calculated retroactively from the base date using the trading value and volume established on the KOSDAQ market for the issuer's shares, and (ii) the base-date volume-weighted arithmetic mean price, determined under the formula below applying a 25% discount rate. However, if the offering price resulting from the discount is at or below par value, par value shall be the issue price. (Amounts below the quotation unit are rounded up to the quotation unit.) Round 2 issue price = reference price x (1 - discount rate) (3) Final issue price: the lower of the round 1 issue price and the round 2 issue price. However, pursuant to Article 165-6 of the Financial Investment Services and Capital Markets Act and Article 5-15-2 of the Regulation on Issuance and Disclosure, etc. 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 rate to the volume-weighted arithmetic mean price for the 3rd to 5th trading days before the subscription date as the reference price, that latter price shall be the final issue price (amounts below the quotation unit are rounded up to the quotation unit). (4) The final issue price will be determined on the 3rd trading day before the first day of the existing-shareholder subscription period and disclosed on the Financial Supervisory Service's electronic disclosure system (DART), and will be announced on the Company's website (http://www.sgholdings.co.kr) in lieu of individual notice.
