주식등의대량보유상황보고서(일반)
Major Shareholding Notification Classification · 96% confidence The document is a detailed report of large shareholdings and changes for a major shareholder and special related parties under the Capital Markets Act (Korea). It includes ownership percentages, thresholds crossed, detailed tables of share counts, change reasons, and background financial information.

기업설명회(IR)개최(안내공시)
Investor Presentation Classification · 82% confidence The document is a formal regulatory notice announcing the date, venue, purpose and materials for an upcoming ‘기업설명회(IR)’ (Investor Relations meeting). It is not an earnings release, board change, or full financial report, nor a Q&A transcript.

기업설명회(IR)개최(안내공시)
Investor Presentation Classification · 95% confidence The document is an announcement about the scheduling and details of an Investor Relations (IR) event, specifically a corporate presentation or roadshow for institutional investors. It includes the date, location, participants, purpose, and a note that the IR materials will be posted on the company's website. The document is short (797 characters) and serves as a notice rather than containing the actual presentation or detailed financial data. Therefore, it fits the category of an Investor Presentation announcement rather than the presentation itself. According to the filing definitions, this is best classified as an Investor Presentation (IP).
2026-05-06 Korean
기업가치제고계획(자율공시)
Regulatory Filings Classification · 80% confidence The document is a voluntary disclosure (“자율공시”) of a corporate value enhancement plan (“기업가치 제고 계획”) including strategic targets and dividend policy. It is not an annual or quarterly report, investor presentation, dividend notice, or share transaction. It is a standalone regulatory announcement of business plans. No specific category fits other than the general regulatory filings fallback. Therefore it is classified as Regulatory Filings (RNS).
