[기재정정]연결재무제표기준영업(잠정)실적(공정공시)
Earnings Release Classification · 100% confidence The document is a formal regulatory filing titled '연결재무제표 기준 영업(잠정)실적(공정공시)' (Provisional Earnings Release based on Consolidated Financial Statements). It provides a correction to previously reported quarterly financial figures (2025.4Q) and includes detailed tables of revenue, operating profit, and net income. As it is an initial announcement of quarterly financial results (key highlights) rather than a full report or a transcript, it falls under the Earnings Release category. Q4 2025

연결재무제표기준영업실적등에대한전망(공정공시)
Regulatory Filings Classification · 95% confidence The document is a 'Fair Disclosure' (공정공시) filing from Seoul Semiconductor, which provides forward-looking guidance on financial performance (revenue projections for Q1 2026) and a comparison of previous forecasts versus actual results. This type of regulatory disclosure regarding earnings guidance and performance updates is classified as an Earnings Release (ER) in our taxonomy, as it provides the initial announcement of financial expectations and results highlights.

매출액또는손익구조30%(대규모법인은15%)이상변동
Management Reports Classification · 95% confidence The document is a regulatory filing from Seoul Semiconductor regarding a significant change (over 15%) in revenue or profit structure. It provides a summary of financial results (revenue, operating profit, net income) for the fiscal year 2025 compared to 2024. It explicitly states that these are preliminary figures prior to external audit and that the final audited report will be submitted later. This fits the definition of an Earnings Release (ER), as it is an initial announcement of financial results highlighting key performance metrics.
2026-02-12 Korean
기업설명회(IR)개최
Report Publication Announcement Classification · 95% confidence The document is an announcement regarding an upcoming Investor Relations (IR) event (기업설명회). It provides the date, time, location, and purpose (discussing Q4 2025 results and Q1 2026 outlook) of a conference call. It does not contain the actual financial results or the transcript of the call, but rather serves as a notification of the event. According to the 'Menu vs Meal' rule, an announcement of an event or report is classified as a Report Publication Announcement (RPA) or Regulatory Filing (RNS). Given the specific nature of announcing an IR event, RPA is the most accurate classification. Q4 2025

연결재무제표기준영업(잠정)실적(공정공시)
Earnings Release Classification · 100% confidence The document is a 'Provisional Earnings Report' (영업(잠정)실적) filed by Seoul Semiconductor. It provides preliminary financial data (revenue) for the 4th quarter of 2025. According to the definitions, an 'Earnings Release' (ER) is the initial announcement of quarterly/periodical financial results, which matches the content of this filing perfectly. It is not a full report, but rather a summary of key highlights. Q4 2025
2026-01-14 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 third quarter of 2025 (2025-07-01 to 2025-09-30). It provides detailed financial figures such as sales revenue for the quarter and cumulative periods, with comparisons to previous quarters and the same period last year. It explicitly states that the figures are provisional and not yet audited. The document also mentions an upcoming IR presentation where more detailed financial statements including profit and balance sheet will be provided. The length of the document is 2745 characters, which is relatively short and the document is primarily focused on financial results for a quarter. This fits the definition of an Interim / Quarterly Report (IR), as it contains substantive financial data and analysis for a period shorter than a full fiscal year. It is not merely an announcement of a report or a certification, but actual provisional financial results. Therefore, the correct classification is IR with high confidence.
