주권매매거래정지해제 (액면병합 주권 변경상장)
Regulatory Filings Classification · 85% confidence The document is a brief notice from a Korean exchange regarding the lifting of a trading suspension for a listed common stock after a reverse share split and listing change. It contains no financial statements, earnings, or in-depth management commentary, and instead is a regulatory announcement about trading status under exchange rules. This matches the fallback category for general regulatory notices. Therefore, it should be classified as a Regulatory Filing (RNS).

임원ㆍ주요주주특정증권등소유상황보고서
Major Shareholding Notification Classification · 95% confidence The document is titled '임원ㆍ주요주주 특정증권등 소유상황보고서' which translates to 'Report on Ownership Status of Specific Securities by Executives and Major Shareholders.' It includes detailed information about securities ownership, changes in holdings, and related dates. The presence of terms like '보고자' (reporter), '임원' (executive), and '주요주주' (major shareholder) indicates this is a notification of share ownership changes by insiders or major shareholders. This matches the definition of Major Shareholding Notification (MRQ). The document length is 2456 characters, which is consistent with a detailed notification rather than a full financial report. Therefore, the correct classification is MRQ with high confidence.
