Correction: Subcontract Payment Methods/Periods & Dispute Resolution Disclosure
Original: [기재정정]지급수단별ㆍ지급기간별지급금액및분쟁조정기구에관한사항
Summary
ISC filed a correction to its semi-annual subcontract payment disclosure for H2 2025 (Jul 1 - Dec 31, 2025), originally submitted on Feb 12, 2026. The only fix is a typo: the 'paid within 10 days' amount was shown as '27,542,' (with a trailing comma) and is corrected to '27,542' (thousand KRW). All substantive figures remain unchanged: total subcontract payments of KRW 30.54 billion, 100% paid in cash, with 93.42% settled within 10-15 days. The filing also reflects the absorption merger of subsidiary I-Semi into ISC. No dispute resolution body has been established.
