Largest Shareholder Donghyun Kim Increases Holdings by 3,000 Shares via Market Purchase and Options, but Ownership Drops to 27.46% Due to Share Dilution, Maintaining Management Control


  • As of the reporting date (2026-05-29), the largest shareholder Donghyun Kim and his special relations hold 3,350,280 shares (27.46%), an increase of 3,000 shares from the previous report, but the total voting shares outstanding increased by 722,831 shares (due to stock option exercises, etc.), resulting in a 1.71 percentage point decline in ownership ratio
  • The changes resulted from open market purchases (Kim 1,000 shares, Bin Jun-gil 2,000 shares) and stock option exercises by special relations Lim Hyun-kook and Kim Chang-il (total 100,580 shares), thereby reducing potential shares (stock options) to 302,700
  • The purpose of holdings remains to influence management (exercising voting rights on director appointments, capital changes, mergers, etc.), with no major contracts (collateral, lending, etc.) in place
  • [AI Summary]Although the largest shareholder increased the number of shares through market purchases and option exercises, the ownership percentage declined due to an increase in total shares outstanding, resulting in a slight dilution risk for existing shareholders. However, the goal of stabilizing management control suggests a low likelihood of near-term control changes, limiting direct impact on the stock price.
