Adjustment of 26th Convertible Bond Conversion Price: Reflecting Stock Merger and Market Decline, Shares Issuable Sharply Reduced but In-the-Money Risk Persists


  • OSUNG ADVANCED MATERIALS adjusted the conversion price of its 26th convertible bond (outstanding 10 billion won) from 1,715 won to 14,890 won.
  • This adjustment reflects the 10:1 stock merger (effective May 7, 2026) and a market price decline (1-month weighted average price of 1,489 won), and was made automatically without a separate board resolution.
  • The number of shares issuable upon conversion decreased sharply from 5,830,904 to 671,591 (approximately 88.5% reduction), lowering nominal dilution, but the conversion price (14,890 won) is close to the post-merger estimated stock price (approx. 14,480 won), increasing the likelihood of conversion.
  • Thus, the risk of equity dilution upon future stock price increases remains, and the adjustment may actually incentivize conversion.
