분기보고서 (2026.03)
Interim / Quarterly Report Classification · 95% confidence The document is titled “분기보고서” (Quarterly Report) covering the period 2026.01.01 to 2026.03.31 and contains comprehensive financial disclosures (company overview, subsidiaries, capital changes, share structure, etc.). It is not a mere announcement but the full interim report itself. Therefore, it best fits the Interim / Quarterly Report category. Q1 2026
2026-05-14 Korean
연결재무제표기준영업(잠정)실적(공정공시)
Interim / Quarterly Report Classification · 95% confidence The document is titled as a preliminary (잠정) earnings report based on consolidated financial statements for the period 2026-01-01 to 2026-03-31, which corresponds to a quarterly period. It provides detailed financial figures such as sales, operating profit, and net income, including comparisons to previous periods. The document explicitly states that the figures are provisional and subject to audit. The length is 2465 characters, which is relatively short, but it contains substantive financial data and analysis, not just an announcement or a link to a report. Therefore, it fits the definition of an Interim / Quarterly Report (IR) rather than an Earnings Release (ER), which typically contains only key highlights without detailed financial tables. It is not a report publication announcement or a certification. Hence, the correct classification is IR with high confidence. Q1 2026
2026-05-06 Korean
기업설명회(IR)개최
Investor Presentation Classification · 95% confidence The document is titled '기업설명회(IR) 개최' which translates to 'Investor Presentation (IR) held'. It details the schedule, location, participants, purpose, and method of an investor presentation event. It mentions that the presentation materials will be posted on the Korea Exchange disclosure system. The content is about organizing and announcing an investor presentation event rather than the presentation materials themselves or a financial report. Therefore, this document fits the category of an Investor Presentation announcement.
2026-05-06 Korean
소속부변경
Regulatory Filings Classification · 95% confidence The document is a brief announcement about a change in the company's classification or department affiliation (소속부변경) from '우량기업부' to '중견기업부' with an effective date. It does not contain financial data, management information, or detailed reports. It is a regulatory announcement about an internal classification change. This fits best under Regulatory Filings (RNS) as it is a general regulatory announcement that does not fit other specific categories.
2026-04-30 Korean
[기재정정]타인에대한채무보증결정
Capital/Financing Update Classification · 82% confidence The document is a formal corporate disclosure of a board resolution to extend and issue guarantees on behalf of an overseas affiliate (“타인에 대한 채무보증 결정”), detailing amounts, periods, related parties, and board approval. This is a financing-related transaction announcement rather than a full financial report or regulatory notice. It falls under updates on financing activities/capital structure changes, so classify as a Capital/Financing Update (CAP).
2026-04-29 Korean
주식등의대량보유상황보고서(일반)
Major Shareholding Notification Classification · 95% confidence The document is a “주식등의 대량보유상황보고서” (Large Shareholding Report) under the Korean Capital Markets Act, detailing the number of shares held by the reporting major shareholder and related parties, changes in holdings, and contracts (e.g., exchangeable bonds). It is a statutory notification of significant share ownership changes (threshold crossing) rather than an announcement of an earnings release or financial report. This aligns exactly with the “Major Shareholding Notification” category (Code: MRQ).
