  • A total of 1,359,751 new shares were issued at 2,574 won per share, resulting in a 29.6% dilution of existing shareholders' equity.
  • The proceeds will be allocated to facility investment for medical device production expansion of 2.5 billion won and working capital of 1.0 billion won, aiming to strengthen long-term growth foundations.
  • Although the largest shareholder has a one-year lock-up period limiting immediate selling pressure, the substantial dilution poses a downside risk to the stock price.
  • [AI Summary]Bistos has completed the capital increase from its largest shareholder, diluting existing shareholders by 29.6%. While the funds are directed towards production capacity expansion for long-term growth, the massive dilution is a negative factor for the stock price. The one-year lock-up mitigates short-term overhang but does not eliminate the structural dilution impact.
