단기차입금증가결정
Capital/Financing Update Classification · 90% confidence The document is a formal announcement of a decision by the company’s board to increase short-term borrowings, detailing the amount, purpose, type of loan, changes in debt levels, and board resolution date. This is clearly an update on the company’s financing activity (debt financing), not a full financial report, regulatory attachment, or share capital change. Therefore it falls under Capital/Financing Update (CAP).

파생상품거래손실발생
Regulatory Filings Classification · 85% confidence The document is a Korean stock disclosure of a material derivative (convertible bond) valuation loss, providing detailed loss amounts, equity impact, causes, and related filing links. It is not a full interim or annual report, nor an earnings release or capital issuance notice. It is a specific regulatory announcement of a loss event. No other category fits, so it should be classified as a general Regulatory Filing (RNS).

분기보고서 (2026.03)
Interim / Quarterly Report Classification · 95% confidence The document is clearly titled “분기보고서” (Quarterly Report) for the 18th fiscal period covering 2026-01-01 to 2026-03-31. It contains substantive sections (company overview, capital changes, share information, business description, etc.) typical of an actual interim/quarterly filing rather than a mere announcement. Therefore, it matches the definition of an Interim / Quarterly Report (IR). Q1 2026

[기재정정]주식등의대량보유상황보고서(약식)
Major Shareholding Notification Classification · 92% confidence The document is a detailed "주식등의 대량보유상황보고서" (report on substantial shareholdings) with tables of current and previous holdings, changes in share counts and percentages by the reporting person and special related parties under Korean capital markets law.

주식등의대량보유상황보고서(약식)
Major Shareholding Notification Classification · 95% confidence The document is a ‘주식등의 대량보유상황보고서(약식)’ detailing the number and ratio of shares held, changes in holdings, acquisition methods and reporting dates under Korea’s Capital Markets Act.
