5. Other matters for investment reference Method of determining the issue price: Under Article 5-18 of the Regulation on Issuance and Disclosure of Securities, the issue price for a shareholder-allotted rights offering may now be freely determined following the abolition of the mandatory pricing procedure and liberalization of price determination; however, out of concern for market disruption and in line with existing practice, the company will determine the issue price applying, in part, the method under Article 57 of the former Regulation on Issuance and Disclosure of Securities.

1) Determination of the first issue price: Using the third trading day before the new-share allotment record date as the base date, the benchmark price is the lower of (i) the simple average of the one-month volume-weighted average price, the one-week volume-weighted average price, and the base-date volume-weighted average price on the KOSDAQ market, and (ii) the base-date volume-weighted average price; the first issue price is determined by the formula below applying a 20% discount rate (amounts below the quotation unit are rounded up to the nearest quotation unit, and if the resulting price is below par value, par value applies). First issue price = benchmark price x (1 - discount rate (20%)) / [1 + (capital increase ratio x discount rate (20%))]

2) Determination of the second issue price: Using the third trading day before the first day of subscription by existing shareholders as the base date, the benchmark price is the lower of (i) the simple average of the one-week volume-weighted average price and the base-date volume-weighted average price on the KOSDAQ market, and (ii) the base-date volume-weighted average price; the second issue price is determined by the formula below applying a 20% discount rate (same rounding and par-value floor as above). Second issue price = benchmark price x (1 - discount rate)

3) Determination of the final issue price: The final issue price is the lower of the first issue price and the second issue price. 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 first and second issue prices is below the price obtained by applying a 40% discount to the volume-weighted average price from the 3rd to the 5th trading day before the subscription date, that latter price (with the same rounding and par-value floor) becomes the final issue price.

4) The final issue price was determined on the third trading day before the existing shareholders' subscription date (July 29, 2026) and will be disclosed on the Financial Supervisory Service's electronic disclosure system on July 30, 2026, and announced on the company's website (www.amotech.co.kr) as specified in the articles of incorporation in lieu of individual notice. Following determination of the final issue price, an amendment report (confirmation of securities issuance terms) will be disclosed on the Financial Supervisory Service's electronic disclosure system.

Note: The issue price for the general public offering of forfeited shares will be the same as the final issue price applied to the existing shareholders' subscription.
