Filing Released Lang Actions
기업설명회(IR)개최
Regulatory Filings Classification · 95% confidence The document is an announcement of an upcoming investor relations roadshow (기업설명회) event, detailing dates, times, location, target audience, purpose, method, sponsor, and IR material posting. It does not contain the actual IR presentation content or financial data, nor is it a report itself. It is a regulatory disclosure of an IR schedule, which best fits the fallback category “Regulatory Filings” (RNS).

분기보고서 (2026.03)
Interim / Quarterly Report Classification · 95% confidence The document is titled “분기보고서 (제11기 1분기)” covering the period 2026-01-01 to 2026-03-31. It provides extensive quarterly financial and operational details (company overview, capital changes, business content, products/services, production capacities, etc.), indicating it is the actual interim/quarterly report rather than an announcement. According to the definitions, this matches an Interim/Quarterly Report (IR). Q1 2026
2026-05-15 Korean
영업(잠정)실적(공정공시)
Earnings Release Classification · 95% confidence The document is titled as a preliminary or provisional business performance announcement (영업(잠정)실적(공정공시)) for the first quarter of 2026, with financial figures presented for the quarter and comparisons to previous periods. It explicitly states that the data is provisional and unaudited, prepared under Korean IFRS, and may be subject to change after external audit review. The document length is 2262 characters, which is relatively short and consistent with a brief earnings announcement rather than a full interim report. There is no detailed financial statement or comprehensive analysis, only summarized key financial metrics. This matches the characteristics of an Earnings Release (ER), which is an initial announcement of quarterly financial results with key highlights only.

소속부변경
Regulatory Filings Classification · 95% confidence The document text indicates a change in the company's department or classification within an exchange or regulatory framework, specifically a change from '기술성장기업부' (Technology Growth Enterprise Division) to '우량기업부' (Excellent Enterprise Division). This is a notice about a change in the company's listing or classification status rather than a financial report, management change, or other detailed filings. The document is very short (236 characters) and is an announcement of a change in the company's status or classification. This fits best under Regulatory Filings (RNS), which is the fallback category for miscellaneous regulatory announcements that do not fit other specific categories.
