Disclosures

Daeduck's subsidiary Daeduck Electronics has approved a KRW 213 billion (approx. USD 155 million) investment to expand its semiconductor product manufacturing facility, equivalent to 23.74% of the subsidiary's equity. The board resolved the decision on May 11, 2026, with construction running through December 31, 2027. The capacity expansion is positioned as a response to rising semiconductor market demand, signaling management's confidence in a multi-year demand cycle. Funding will come from internal cash and external borrowings, introducing some leverage risk but spreading capex over roughly 20 months. The scale is material but does not classify as a large-scale corporate transaction under Korean disclosure rules.

Park Systems outside director Park Ki-jun filed an initial report of ownership in specified securities, disclosing 1,000 common shares (0.01% of outstanding) acquired through a stock option exercise on April 30, 2026. The exercise price was KRW 163,040 per share, and the report notes that share payment has been completed with listing procedures still in progress. This is a small, routine insider acquisition tied to equity compensation rather than open-market buying, and the stake is immaterial relative to Park Systems' 6,997,557 total shares outstanding. The filing signals director alignment with shareholders but carries limited informational value about company fundamentals or near-term outlook.

DB HiTek disclosed the latest exercise of exchange rights on its 121st series unregistered, zero-coupon, unsecured private exchangeable bonds, which are exchangeable into the company's treasury shares. Cumulative exercises (excluding previously reported amounts) total 441,990 shares, equivalent to 1.02% of total shares outstanding (43,504,588). The most recent exercise on May 11, 2026 converted KRW 5 billion of bonds at an exchange price of KRW 56,562, delivering 88,398 shares. Of the original KRW 125.57 billion issuance, KRW 18 billion in unexchanged bonds remain, representing a potential further 318,234 shares. Because the underlying shares are treasury stock rather than newly issued, this exercise does not dilute existing shareholders but does increase the public float.

Hanmi Semiconductor will host a group conference call on May 12, 2026, hosted by CLSA, targeting major European institutional investors to outline the company's business status and strategic direction. Management plans to highlight three new market entries: system semiconductor packaging (foundry/OSAT) with the launch of 2.5D Package TC Bonders (40 and 120 models), a new TC Bonder concept addressing the emerging HBF (High Bandwidth Flash) market driven by AI memory demand, and participation in a US-led AI semiconductor alliance to capture demand for AI packaging equipment. The disclosure signals a deliberate diversification beyond Hanmi's core HBM TC bonder franchise into adjacent high-growth AI-driven segments. The IR is informational rather than transactional, but the explicit roadmap into HBF and US AI alliances may shape investor expectations on the company's TAM expansion.

CEO Kim Chul Ho filed an amended major shareholding report following an on-market sale by a related party, with the reporting group's combined stake decreasing by 706 shares to 3,219,696 shares. Despite the share count reduction, the ownership ratio remains unchanged at 29.11% of the 11,061,429 voting shares outstanding. The number of related parties declined from 10 to 9, suggesting one related party exited the reporting group entirely. The stated purpose remains influence over management control, consistent with Kim's role as CEO. The transaction is immaterial in size and unlikely to signal any meaningful shift in insider sentiment or control structure.

Park Systems will hold an Investor Relations event on May 12, 2026, at the Shilla Hotel in Seoul, participating in the Samsung Securities Global Conference. The event targets both domestic and international institutional investors and runs from 10:00 to 15:50 local time. Management will provide updates on business performance and current operations. IR materials will be available on the KRX disclosure system (kind.krx.co.kr) starting May 11, 2026. This is a routine investor outreach event without new financial disclosures announced in advance.

Hyun Chang-hoon, a newly appointed non-registered Managing Director (appointed February 1, 2026), filed an initial insider ownership report disclosing the purchase of 500 common shares on May 8, 2026. The shares were acquired via open-market purchase at 168,800 KRW per share, representing a total transaction value of approximately 84.4 million KRW. The resulting ownership stake is negligible at 0.00% of the 11,061,429 total shares outstanding. As a small, initial filing by a newly-appointed executive rather than a major shareholder, this transaction carries minimal signaling value but indicates modest insider alignment with shareholders.

A non-registered executive (Managing Director Lee Gyoo-chul, Development Team) filed a change report on his ownership of company securities as of May 6, 2026. He bought 102 preferred shares at KRW 185,000 and sold the same 102 shares at KRW 183,400 on the same day, resulting in a small intraday loss. After the trades, his holdings returned to 243 common shares and 0 preferred shares (down from 102), with the common-share count unchanged. The transaction is immaterial in size (0.00% of outstanding shares) and reflects a personal trading event rather than any strategic insider action.
