[기재정정]분기보고서 (2026.03)
Interim / Quarterly Report Classification · 95% confidence The document is a Korean ‘분기보고서’ (quarterly report) for the period January 1 to March 31, 2026, containing full financial statements, company overview, history, capital movements, and detailed correction (정정신고) of the originally filed quarterly report. The length (180,526 characters) and substantive financial content confirm this is the actual interim/quarterly report itself rather than a mere announcement or certification. Therefore, it should be classified as an Interim / Quarterly Report. Q1 2026

파생상품거래손실발생
Regulatory Filings Classification · 85% confidence The document is a Korean stock exchange disclosure announcing a derivative transaction loss (conversion bond embedded derivative), outlining loss amount, equity impact, cause, and references to related filings. It does not contain full financial statements or constitute a quarterly/interim report, nor is it a proxy or dividend notice. It is a standalone regulatory event announcement that does not fit other specific categories, so it falls under the general Regulatory Filings category (RNS).

주요사항보고서(자기전환사채만기전취득결정)
Regulatory Filings Classification · 72% confidence The document is a mandatory Korean stock exchange major event report (“주요사항보고서”) announcing the company’s decision to repurchase its own convertible bonds before maturity. It contains no substantive financial statements or earnings data, nor is it an AGM or management report. It is not a share repurchase under “Transaction in Own Shares” (which covers equity only), nor a capital raise. Therefore it falls under the miscellaneous regulatory announcement category: Regulatory Filings (RNS).
