Filing Released Lang Actions
주식등의대량보유상황보고서(약식)
Major Shareholding Notification Classification · 92% confidence The document is a 주식등의 대량보유상황보고서, a statutory large shareholding report detailing changes in the number and percentage of shares held by Samsung Asset Management. This corresponds to a major shareholding notification rather than a management report, earnings release, or any other category.
2026-05-29 Korean
기업설명회(IR)개최
Regulatory Filings Classification · 92% confidence The document is a brief regulatory announcement of an upcoming investor relations (IR) meeting (기업설명회) – providing dates, location, target audience, and where IR materials will be posted. It does not contain the actual presentation content or detailed financial slides, so it is not an Investor Presentation (IP) itself but rather a general disclosure. This fits the catch-all Regulatory Filings category (RNS).
2026-05-21 Korean
분기보고서 (2026.03)
Interim / Quarterly Report Classification · 95% confidence The document is the company’s ‘분기보고서’ (quarterly report) for the period January 1 – March 31, 2026. It contains detailed financial statements, segment revenues, subsidiary information, capital changes, governance updates, and full tables as required in a statutory interim report. It is clearly the substantive quarterly report itself (not merely an announcement), fitting the definition of an Interim/Quarterly Report (IR). Q1 2026
2026-05-15 Korean
연결재무제표기준영업(잠정)실적(공정공시)
Interim / Quarterly Report Classification · 95% confidence The document is titled as a preliminary (잠정) earnings performance report based on consolidated financial statements for the first quarter of 2026. It contains detailed financial data such as sales, operating profit, and net income for the current quarter, previous quarter, and prior year quarter, along with percentage changes. The document explicitly states that these are provisional figures subject to audit confirmation. The length is 3696 characters, which is relatively short but contains substantive financial data and analysis, not merely an announcement or a certification. The content matches the characteristics of an Interim / Quarterly Report (IR) as it covers a period shorter than a full fiscal year and provides actual financial results and comparisons. Therefore, the appropriate classification is IR (Interim / Quarterly Report). Q1 2026
2026-05-07 Korean
주식등의대량보유상황보고서(약식)
Major Shareholding Notification Classification · 100% confidence The document is a detailed report about large shareholding positions and changes thereof, including specific share counts, percentages, dates, and descriptions of transactions by a major shareholder (Mirae Asset Global Investments). It includes legal references to capital market laws and reporting requirements for large shareholdings. The content is focused on notifying regulatory bodies and the market about significant share ownership and changes, not about financial performance, management changes, or other corporate events. This matches the definition of a Major Shareholding Notification (MRQ). The document length is sufficient and contains detailed data, not just an announcement or certification, so it is not a Regulatory Filing (RNS) or Report Publication Announcement (RPA).
2026-05-04 Korean
주식소각결정
Share Issue/Capital Change Classification · 87% confidence The document is a corporate announcement in Korean titled “주식소각 결정,” detailing the decision to cancel treasury shares (444,368 common shares), the timing, accounting values, and board resolution date. This is a capital structure change (share cancellation), not a full report. According to the filing definitions, share cancellations fall under Share Issue/Capital Change (SHA).
