Change in Largest Shareholder from Seo Seong-seok to Lee Byung-man... Ownership Slightly Rises to 63.01%, Reshuffling Among Existing Related Parties


  • The largest shareholder changed from Seo Seong-seok and 6 related parties (62.98% ownership) to Lee Byung-man and 9 others (63.01%).
  • The reason is an over-the-counter sale under a stock purchase agreement, where Seo Seong-seok sold 421,670 shares each to corporations SSY and BJH, which are newly included as related parties.
  • The new largest shareholder group consists of existing related parties, resulting in a reshuffling of ownership structure without change in management control.
  • [AI Comprehensive Analysis]This change is merely a redistribution among existing related parties, with no material impact on the company's strategy or financials. Neutral for shareholder value, no specific risks.
