What happened

Rights Offering: Round-1 Issue Price Decision

1. Planned issuance details: a. Type of shares: Registered common shares b. Number of shares: 3,700,000

2. Round-1 issue price (per share): KRW 39,100

3. Par value (KRW): 500

4. Round-1 issue price calculation date: 2026-09-01

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 12, 2026 per the formula below. Under Article 5-18 of the Regulation on Issuance and Disclosure of Securities, the issue price for a shareholder-allocated capital increase may now be freely determined following the abolition of the pricing procedure and the liberalization of price-setting; however, out of concern for market disruption and in line with existing practice, the Company plans to determine the price by applying, by analogy, Article 57 of the former Regulation on Issuance and Disclosure of Securities, as follows.

a. Round-1 issue price: 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 volume-weighted average 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 volume-weighted average price on the base date; a 25% discount is then applied per the formula below. 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)]

b. Round-2 issue price: Determined using, as the reference share price, the lower of (i) the average of the 1-week volume-weighted average price and the volume-weighted average 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 volume-weighted average price on the base date; a 25% discount is then applied per the formula below. 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)

c. Final issue price: 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), that latter price (applying the 40% discount) is used as the final 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. > Final issue price = Max[Min(round-1 issue price, round-2 issue price), 60% of the reference share price]

d. Final determined price: Will be determined on the third trading day before the first day of the existing shareholders' subscription period, disclosed on the Financial Supervisory Service's electronic disclosure system (DART), and announced on the Company's website (http://www.lncbio.co.kr) in lieu of individual notice.

The general public offering issue price will be the same as the final issue price applied to the existing shareholders' subscription.
