Disclosures

Kang Kun Hyuk, a non-registered executive (Sangmu/Vice President) at Samsung Austin Semiconductor (Samsung's U.S. research arm), filed his first insider ownership report covering activity from his September 2021 appointment through June 2026. Total holdings stand at 428 shares (common + preferred combined), accumulated through small open-market purchases starting at KRW 58,200–79,100 in 2021–2022 and resuming at KRW 168,300–205,000 per share in March–April 2026. Two forced sales (반대매매) in April 2026 totaling 9 common shares were triggered to cover margin call shortfalls of KRW 81,880 and KRW 1,066,840. The position represents 0% of outstanding shares (6.74 billion) and carries no material signaling value beyond confirming the executive's personal accumulation pattern.

The first issue price for the rights offering with public subscription of unsubscribed shares has been confirmed at KRW 4,125 per share, down from the previously indicated KRW 4,150. Total offering size decreases slightly to KRW 49.5 billion (from KRW 49.8 billion) for 12,000,000 common shares. Use of proceeds remains KRW 30 billion for facility investment and KRW 19.5 billion for operating capital. KB Securities serves as the lead underwriter on a firm-commitment basis. The existing shareholder subscription period is July 29-30, 2026, with general public subscription on August 3-4 and payment due August 6. The final issue price will be determined three business days before the subscription date.

LB Corp, the de facto controlling shareholder, filed a trading plan to purchase 2,271,295 subscription warrants (신주인수권증서) through off-exchange (OTC) acquisition between July 20-23, 2026, at an indicative price of KRW 4,125 per share, totaling approximately KRW 9.37 billion. The purpose is to participate in the rights offering (shareholder allocation plus public offering of forfeited shares). Following completion, LB Corp's holdings (common shares + warrants) would rise from 5,823,200 shares (9.86%) to 8,094,495 shares (13.19%) of the issued share count. The actual price will be determined by the 5-business-day average closing price during warrant trading (July 10-16, 2026) and may differ from the indicative figure; actual transaction size can vary within ±30% per regulation.

A newly appointed managing director, Lee Keun-pil, filed his initial report on ownership of specific securities after purchasing 301 common shares on the open market on June 11, 2026 at KRW 38,507 per share. The total holding represents just 0.00% of the 12,253,025 outstanding shares, amounting to roughly KRW 11.6 million in value. The filing is a routine disclosure triggered by his appointment as a registered managing director on March 24, 2026. While the absolute transaction size is small, insider purchases by newly appointed executives are often viewed as a mild signal of confidence in the company.

Largest shareholder and CEO Lee Sang-ryul filed an updated major shareholding report as of June 12, 2026. While he and related parties acquired 491 additional shares, the total holding ratio fell sharply from 64.04% to 54.20% (-9.84pp) because the total issued shares ballooned from 10,000,000 to 12,253,025 following convertible bond (CB) conversion into common stock. Voting-right ratio also dropped from 55.42% to 45.24% (-10.18pp), meaning the controlling group now holds less than half of voting rights. The number of special-related parties increased from 12 to 14. The filing reaffirms management-control purpose, but the dilution from CB conversion is a meaningful overhang for minority shareholders.

Individual investor Park Young-ok, CEO of Smart Income Co., increased his combined stake (including affiliate Smart Income) from 6.69% to 7.15%, acquiring 66,082 additional shares through open-market purchases between June 9 and June 17, 2026. The purchases were made at prices ranging from KRW 5,886 to KRW 7,395 per share, signaling continued accumulation by a well-known value investor. The stated purpose remains 'simple investment,' not management influence. Park personally now holds 979,313 shares (6.76%), while Smart Income holds 56,108 shares (0.39%), for a total of 1,035,421 shares.

The company has set June 18, 2026 as the ex-rights date for its previously announced paid-in capital increase (rights offering). The reference base price has been adjusted to KRW 5,310 to reflect the dilution from new share issuance. Shareholders who do not hold shares before the ex-rights date will not be entitled to subscribe to the new shares. This is a routine procedural step in the rights offering process, but the base price reset typically causes a visible drop in the quoted share price.
