기업설명회(IR)개최
Investor Presentation Classification · 75% confidence The document is an announcement of a 예정된 기업설명회(IR) event, listing date, time, venue, participants, purpose, and where IR materials will be posted.

기업가치제고계획(자율공시) ((2025년 이행현황))
Regulatory Filings Classification · 95% confidence The document is titled '기업가치 제고 계획(자율공시)' which translates to 'Corporate Value Enhancement Plan (Voluntary Disclosure)'. It includes a plan name, key content about targets and performance evaluation, dividend information, and a decision date. The document mentions that detailed information is available in an attached report but does not itself contain comprehensive financial statements or detailed analysis. The length is only 1636 characters, which is quite short and more consistent with an announcement or summary rather than a full report. The document is a voluntary disclosure about the company's corporate value enhancement plan and its implementation status, including dividend details. This fits best under the category of Regulatory Filings (RNS) as it is a regulatory announcement of a plan and its status, not a full annual or interim report, nor a detailed investor presentation or earnings release.

[기재정정]임원ㆍ주요주주특정증권등소유상황보고서
Director's Dealing Classification · 92% confidence The document is a detailed correction to the “임원ㆍ주요주주 특정증권등 소유상황보고서,” which is a statutory insider share ownership and transaction disclosure filed by a company director (an executive) and major shareholder. It lists shareholdings, changes (acquisitions/disposals), transaction dates, and corrected transaction price. This matches our “Director's Dealing” category, which covers insider share transactions by directors/executives. It is not a simple announcement of a report, nor an annual/interim report, but the actual insider transaction report form.

This matches the definition of a Major Shareholding Notification (MRQ). There is no indication this is an announcement of a report publication or an earnings release, but rather the substantive report itself.
