Filing Released Lang Actions
임원ㆍ주요주주특정증권등소유상황보고서
Director's Dealing Classification · 95% confidence The document is a statutory insider report (‘임원ㆍ주요주주 특정증권등 소유상황보고서’) filed with the securities regulator and stock exchange, detailing the holdings and transactions of an executive. This matches the Director’s Dealing category (insider share transactions by directors/executives).
2026-06-01 Korean
주식등의대량보유상황보고서(일반)
Major Shareholding Notification Classification · 95% confidence The document is a detailed regulatory report titled “주식등의 대량보유상황보고서(일반),” filed with the Financial Services Commission and Korea Exchange, detailing shareholdings, percentage thresholds, related parties, and changes in ownership. This corresponds to a Major Shareholding Notification – a report of substantial share ownership levels and changes by a shareholder crossing reporting thresholds. It is not a company annual or interim report, nor a capital markets announcement of a company report, but a standard substantial shareholding filing.
2026-06-01 Korean
분기보고서 (2026.03)
Interim / Quarterly Report Classification · 98% confidence The document is a Korean ‘분기보고서’ (quarterly report) covering the first quarter of the 75th fiscal period (2026-01-01 to 2026-03-31), filed with the Financial Services Commission and Korea Exchange. It runs over 182,000 characters, includes full financial statements, segment data, business overviews, and actual sales and cost tables. This matches the definition of an Interim/Quarterly Report (“IR”) rather than an announcement or summary. Q1 2026

임원ㆍ주요주주특정증권등거래계획보고서
Director's Dealing Classification · 92% confidence The document is a Korean ‘임원ㆍ주요주주 특정증권등 거래계획보고서’, which is a scheduled transaction plan report by an executive (director) detailing planned gifts and disposals of shares. This falls squarely under insider/dealer transaction reporting by company directors. It is not a corporate report like an Annual or Quarterly report nor an announcement of dividends or capital structure changes, but rather a report of a director’s personal share dealings. Therefore the correct classification is Director's Dealing (DIRS).
2026-04-29 Korean
정기주주총회결과
Declaration of Voting Results & Voting Rights Announcements Classification · 93% confidence The document text is the formal release of the results of the company’s annual general meeting (정기주주총회 결과), detailing approved financial statements, dividend resolutions, board appointments, and voting tallies for each agenda item. This matches the definition of “Declaration of Voting Results & Voting Rights Announcements” (Code: DVA). It is not a notice that a report is published, but the actual voting results from the AGM.
2026-03-27 Korean
사업보고서 (2025.12)
Annual Report Classification · 100% confidence The document is a 'Business Report' (사업보고서) for the 74th fiscal year (2025), which is the Korean equivalent of an Annual Report (10-K). It contains comprehensive company information, financial data, business descriptions, and management details. It is a full-length regulatory filing submitted to the Financial Services Commission and the Korea Exchange, not an announcement or a summary. FY 2025
