매출액또는손익구조30%(대규모법인은15%)이상변동
Management Reports Classification · 95% confidence The document is a regulatory filing from a Korean company (SamCNS) announcing a significant change (over 30%) in revenue or profit structure. This is a standard disclosure requirement in the Korean stock market (KRX) for listed companies to report preliminary financial results before the final audit is completed. Since it provides key financial highlights (revenue, operating profit, net income) for the fiscal year, it fits the definition of an Earnings Release (ER).

전환청구권행사
Capital/Financing Update Classification · 95% confidence The document is a regulatory filing from the Korea Exchange (KRX) regarding the exercise of conversion rights (전환청구권행사) for convertible bonds. This involves the issuance of new shares resulting from the conversion of debt into equity, which directly impacts the company's capital structure and share count. According to the provided definitions, announcements regarding new share issues or capital changes fall under the 'SHA' category.

주식등의대량보유상황보고서(약식)
Major Shareholding Notification Classification · 100% confidence The document is a 'Report of Large Shareholding' (주식등의 대량보유상황보고서) filed in South Korea. This type of filing is required when an entity's shareholding in a listed company crosses certain thresholds (typically 5%). It details the identity of the shareholder, the number of shares held, the purpose of the holding (in this case, 'simple investment'), and a history of transactions (share sales). This corresponds to the 'Major Shareholding Notification' category.

영업(잠정)실적(공정공시)
Earnings Release Classification · 95% confidence The document is titled as a preliminary (잠정) earnings performance announcement for the third quarter of 2025, covering the period from July 1, 2025 to September 30, 2025. It contains summarized financial data such as sales, operating profit, and net income for the quarter and cumulative periods, with comparisons to previous quarters and the same period last year. The document explicitly states that the figures are provisional and unaudited, prepared under Korean IFRS, and may be subject to change after external audit review. The document length is 2261 characters, which is relatively short and appears to be a concise earnings announcement rather than a full interim or quarterly report with detailed financial statements and analysis. It is a typical format for an earnings release (initial announcement of quarterly financial results) rather than a comprehensive interim report. Therefore, the appropriate classification is Earnings Release (ER).

기업설명회(IR)개최
Investor Presentation Classification · 95% confidence The document is titled '기업설명회(IR) 개최' which translates to 'Investor Relations Presentation (IR) held'. It details the schedule, location, participants, purpose, and method of an investor presentation event, including the date and time, target audience (institutional investors), and content (business overview and Q&A). There is no financial data or report content included, only information about the event itself. This matches the definition of an Investor Presentation (IP), which is a detailed presentation for investors focusing on financials, strategy, and market position. The document length is short and it is clearly an announcement of the IR event, not a full financial report or earnings release. Therefore, the correct classification is Investor Presentation (IP).

주식등의대량보유상황보고서(약식)
Major Shareholding Notification Classification · 100% confidence The document is titled '주식등의 대량보유상황보고서(약식)' which translates to 'Report on Large Shareholding Status (Abbreviated)'. It details the number of shares held, changes in shareholding, and related information about a specific investor (Daishin New Technology Investment Fund 11th) in a company (Sam CNS Co., Ltd.). The document includes dates of shareholding changes, reasons for changes, and the purpose of holding shares (simple investment). This matches the description of a Major Shareholding Notification, which reports changes in significant share ownership levels. The document is not an annual report, earnings release, or any other type of report but specifically a notification of large shareholding changes as required by capital market regulations.
