  • Largest shareholder Oh Yeongseop's specific securities (common shares + convertible bonds) decreased by 80% from 13.49 million to 2.70 million due to a 5:1 reverse stock split and conversion price adjustment
  • Pre-split common shares of 12.86 million (29.97%) reduced to 2.57 million (28.67%) post-split, a 1.30pp decline; convertible bonds also reduced from 634,417 to 126,883
  • Minor ownership decline attributable to changes in total shares from conversion rights exercises, not the split itself; limited dilution impact
  • No share buyback, cancellation, or dividend information is included in this disclosure
  • [AI Summary]This filing is a routine mandatory report of a major shareholder's ownership change. The reduction in shares due to the reverse split is a mere adjustment, and the slight dilution from conversion adjustments does not constitute a material positive or negative event for shareholder value.
