OPTRONTEC Completes 25 Billion Won 18th CB Issuance... Rising Concerns over Shareholder Dilution


  • OPTRONTEC completed the issuance of the 18th series of unsecured private convertible bonds worth 25 billion won (approximately 40% of market cap)
  • The CBs are not scheduled to be listed, and future conversion could increase market supply and dilute existing shareholders' stakes
  • Conversion terms (conversion price, etc.) need to be verified via separate disclosures; typically, private CBs are issued at a discount, amplifying dilution risk
