Corentec's Controlling Shareholder Seon Du-hun Slightly Reduces Stake by 0.07% Due to Pledge Extension and Open Market Trading


  • The total stake of Corentec's de facto controlling shareholder Seon Du-hun and 16 special relations slightly decreased from 21.14% to 21.07% (down 10,268 shares, or 0.07%p).
  • The decrease was due to the sale of 18,097 shares by special relation Seon Hyung-hoon on April 8, 2026, partially offset by Seon Du-hun's purchase of 7,829 shares on May 22, 2026. The net selling volume is negligible and does not affect control.
  • Seon Du-hun and two special relations (Seon Seung-hoon and Seon Kyung-hoon) extended their share pledge agreements with Hana Bank for one year. The pledged shares total 1,108,775 (8.02% of voting shares), with loan balances of KRW 1.5 billion, KRW 700 million, and KRW 700 million respectively (total KRW 2.9 billion), at interest rates of 3.576%-3.786%.
  • The pledge extension is a routine renewal of existing loans, not new financing or dilution. However, the large pledged amount could pose a risk if the stock price declines, potentially triggering margin calls.
  • [AI Comprehensive Analysis]This disclosure reflects routine changes in the controlling shareholder's holdings and pledge renewal, with no direct impact on corporate value or shareholder returns. The slight stake reduction and pledge extension pose no major threat to management stability, but the size of pledged shares remains a potential risk factor.
