주주명부폐쇄기간또는기준일설정
Regulatory Filings Classification · 95% confidence The document is a formal notice regarding the setting of a record date and the closure of the shareholder register for the purpose of determining voting rights for an upcoming Annual General Meeting (AGM). This type of regulatory disclosure is a standard corporate announcement regarding shareholder meeting preparations and does not fit into the specific report categories like 10-K or IR. Given it is a regulatory announcement regarding corporate governance and meeting logistics, it falls under the RNS category.

기업설명회(IR)개최
Investor Presentation Classification · 95% confidence The document is an announcement of an upcoming Investor Relations (IR) event, specifically a corporate presentation scheduled for November 21, 2025. It details the event's date, time, location, participants, purpose, and agenda but does not contain any financial data or results. It also states that the IR materials will be posted on the day of the event. This matches the definition of an Investor Presentation (IP) as it is a detailed presentation for investors focusing on financials, strategy, and market position, even though the actual presentation materials are not included here. The document is not a report itself but an announcement of the event and its details, which fits best under the Investor Presentation category rather than a report publication announcement or regulatory filing.

Report Publication Announcement Classification · 100% confidence The document is a short, structured announcement reporting the results of an Investor Relations (IR) meeting held by the company. It lists the date, location, attendees, and agenda of the meeting. Since it is a brief notification regarding the occurrence and outcome of an IR event rather than the full presentation slides or a comprehensive financial report, it falls under the category of general regulatory announcements or event notifications.
