Major Shareholder Yoon Jong-chan's Stake Drops to 35.92% After Gifting 60,000 Shares... Total Shares Increased Due to Conversion


  • On May 28, 2026, Yoon Jong-chan, the largest shareholder and CEO, gifted 60,000 common shares to four individuals: Kim Hong-su (20,000), Kim Ki-young (20,000), Kim Dae-hyun (10,000), and Kim Soo-hyun (10,000).
  • As a result, Yoon's shareholding decreased from 3,625,320 shares (39.73%) to 3,565,320 shares (35.92%), a drop of 3.81 percentage points.
  • Total outstanding shares increased from 9,125,174 (as of March 31, 2023) to 9,925,885 due to conversion rights exercised on September 8, 2025.
  • Since the gifts were made without consideration, there is no direct market impact. However, the reduction in the largest shareholder's stake may slightly weaken management stability.
  • [AI Comprehensive Analysis]This is a routine disclosure of a change in major shareholder ownership. The gifts themselves do not directly affect corporate value. However, the continued decline in the largest shareholder's stake, combined with the increase in total shares from conversions, may pose an overhang risk in the medium to long term, warranting investor caution.
