Filing Released Lang Actions
[기재정정]단일판매ㆍ공급계약체결(자율공시)
Regulatory Filings Classification · 78% confidence The document is a Korean voluntary disclosure (“자율공시”) of a single sales and supply contract and its subsequent correction notice, detailing contract terms, amounts, parties, and extension of the contract period. It does not contain financial statements, earnings metrics, or management analysis, nor is it calling for voting or dividends. It is essentially a regulatory announcement of a business contract. There is no specific category for contract announcements, so it falls into the general “Regulatory Filings” fallback category.
2026-05-19 Korean
분기보고서 (2026.03)
Interim / Quarterly Report Classification · 95% confidence The document is a Korean "분기보고서" covering the period 2026-01-01 to 2026-03-31 and contains detailed quarterly financial statements, segment information, business overview, and analysis. It is clearly a comprehensive interim/quarterly report rather than an announcement or presentation. Thus it falls under Interim / Quarterly Report (IR). Q1 2026

임원ㆍ주요주주특정증권등소유상황보고서
Director's Dealing Classification · 95% confidence The document is a ‘임원ㆍ주요주주 특정증권등 소유상황보고서’, i.e. a report on securities holdings and transactions by an officer (Byun Ki Soo). It details changes in share ownership, dates of acquisition/disposal, number of shares and percentage holdings. This matches the definition of Director’s Dealing (insider share transactions by company directors/executives). Therefore, it should be classified as DIRS.
2026-04-21 Korean
주식등의대량보유상황보고서(일반)
Major Shareholding Notification Classification · 93% confidence The document is a Korean regulatory ‘주식등의 대량보유상황보고서(일반)’ (Report on large shareholding), detailing changes in share holdings, parties, holdings and voting rights under the Capital Markets Act. This clearly corresponds to a Major Shareholding Notification filing. Therefore, it is classified as MRQ.
2026-04-20 Korean
주식소각결정
Share Issue/Capital Change Classification · 83% confidence The document is an official announcement of a board resolution to cancel (소각) 700,000 treasury shares, specifying the number of shares, book value, planned cancellation date, legal basis under the Korean Commercial Code, and post-cancellation share status. This is a corporate action involving a change in capital structure (capital reduction via share cancellation). It is not a financial report or regulation filing but a capital change announcement. Therefore, it fits ‘Share Issue/Capital Change (SHA)’.
