Slight decrease in largest shareholder stake (66.83%→66.37%) due to stock merger and change in related parties, highlighting high pledge ratio (59.73%) risk


  • As of the report date, the stake of largest shareholder Woongjin in Woongjin Thinkbig decreased slightly from 66.83% to 66.37% due to the retirement of a related party executive and a 2:1 stock merger (shares reduced from 115,505,985 to 56,827,085).
  • Woongjin Thinkbig cancelled 1,851,814 treasury shares in March 2026 (from 7,407,257 to 5,555,443), and the subsequent stock merger further reduced total shares, enhancing per-share value.
  • All of Woongjin's 33,945,457 shares (59.73% stake) are pledged as collateral for loans from Hana Bank, iM Bank, KDB, etc., with total loans of 130 billion KRW. The collateral value at current price (~47.9 billion KRW) is far below the loan amount, posing a risk of margin calls if the stock price declines further.
  • [AI Summary]This disclosure is essentially a routine update due to stock merger and related party change, but the controlling shareholder's high pledge ratio (59.73%) and large debt (130 billion KRW) represent significant downside risk, as a drop in stock price could trigger additional collateral demands or forced selling.
