임원ㆍ주요주주특정증권등소유상황보고서
Director's Dealing Classification · 84% confidence The document is a mandatory insider ownership report (“임원ㆍ주요주주 특정증권등 소유상황보고서”) filed with Korean regulators, detailing current shareholdings and changes by an executive/major shareholder. It is not a company share buyback, threshold‐crossing threshold notification (shares remain above 10%), or a general corporate report announcement. It falls under “Director’s Dealing” – insider share transactions and holdings. Hence DIRS.

임원ㆍ주요주주특정증권등소유상황보고서
Director's Dealing Classification · 98% confidence The document is an insider holdings report filed with the Securities and Exchange Commission equivalents, disclosing an executive/major shareholder’s changes in share ownership. It provides details on the number of shares held before and after the transaction, dates, and nature of the change. This matches the definition of Director’s Dealing (insider transactions) rather than a general report, announcement, or financial statement.

주식등의대량보유상황보고서(일반)
Major Shareholding Notification Classification · 95% confidence The document is titled “주식등의 대량보유상황보고서(일반)” which translates to a report on large shareholding positions, detailing changes in share counts, ownership percentages, report dates, holding purposes, and triggering events under the Capital Markets Act. It is a statutory notification of major share ownership changes, not a management report or earnings release. This clearly matches the Major Shareholding Notification category.

전환가액의조정 (제25회차)
Capital/Financing Update Classification · 85% confidence The document is a regulatory disclosure announcing the adjustment of the conversion price for the company’s 25th tranche convertible bonds (“전환가액의 조정”). It details pre‐ and post‐adjustment conversion prices, reasons (share consolidation and price decline), calculation method, dates, and related chart. This is not a financial report or audit, nor a dividend or management change. It is an update to the terms of a financing instrument (convertible debt), i.e., a change in the company’s capital/financing structure. Accordingly, it fits the “Capital/Financing Update” category.
2026-05-18 Korean
분기보고서 (2026.03)
Interim / Quarterly Report Classification · 91% confidence The document is labeled as a “분기보고서” (quarterly report) for the period January 1, 2026 to March 31, 2026 (33rd term), contains detailed sections including company overview, subsidiaries, credit ratings, share capital changes, treasury share details, corporate governance amendments, and other substantive financial and corporate data rather than a mere announcement. It constitutes a full interim/quarterly report. Therefore, it fits the “Interim / Quarterly Report” category. Q1 2026
2026-05-15 Korean
주주총회소집결의 (임시주주총회)
Regulatory Filings Classification · 90% confidence The document is a board resolution to convene an extraordinary shareholders’ meeting (“주주총회소집결의”), outlining date, venue, record date, and agenda item but not providing full meeting materials or proxy forms. It is not an Annual Report, interim report, earnings release, dividend notice, or proxy statement; rather it is a general regulatory announcement of the board’s decision to call a shareholders’ meeting. Therefore it falls under the fallback category “Regulatory Filings (RNS).”
