Filing Released Lang Actions
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
2026-05-15 Korean
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).

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.

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
2026-03-19 Korean
감사보고서제출
Audit Report / Information Classification · 99% confidence The document is a regulatory filing from a Korean company (Union) titled 'Audit Report Submission' (감사보고서 제출). It provides the audit opinion, key financial data (assets, liabilities, equity, profit/loss), and details regarding the external auditor. While it contains financial data, it is a standard regulatory disclosure form used in the Korean market to announce the receipt and filing of the audit report, rather than the full annual report document itself. Therefore, it is classified as an Audit Report / Information (AR). FY 2025
2026-03-19 Korean
주주총회소집결의
