주식등의대량보유상황보고서(일반)
Major Shareholding Notification Classification · 95% confidence The document is the Korean “주식등의 대량보유상황보고서(일반)” – a mandatory large‐shareholding status report under Korea’s Capital Markets Act. It details major shareholder identities, share counts, percentages, changes and related contracts (e.g., share pledge agreements). It is clearly a notification of significant share ownership levels and changes, matching the “Major Shareholding Notification” category rather than an earnings release, management change or other filing.

주식등의대량보유상황보고서(약식)
Major Shareholding Notification Classification · 90% confidence The document is a detailed “주식등의 대량보유상황보고서(약식)” (Large Shareholding Status Report) filed by the National Pension Service reporting its holdings and changes. This is exactly the regulatory “Major Shareholding Notification” category, as it discloses significant share ownership levels and changes. It is not an earnings release, board change, or general regulatory announcement. Therefore, it is classified as MRQ.

[기재정정]최대주주변경을수반하는주식담보제공계약체결
Regulatory Filings Classification · 80% confidence The document is a Korean stock-exchange regulatory disclosure (“정정신고”) regarding the correction of a previously announced share‐pledge contract involving the controlling shareholder. It details dates, parties, amounts of shares pledged as collateral, and related contractual terms. This is not a full financial report (10‐K/IR), not an earnings release (ER), not a management/board change (MANG), nor a capital raise announcement (CAP) in the strict sense. It is a standard regulatory announcement/fallback category. Therefore, it should be classified as a general regulatory filing (RNS).

This matches the “Major Shareholding Notification” category (MRQ).

[기재정정]최대주주변경을수반하는주식담보제공계약체결
Regulatory Filings Classification · 85% confidence The document is a KRX regulatory disclosure (“정정신고(보고)”) correcting details of a major‐shareholder share collateral (pledge) contract. It is not a full financial report (10-K/IR), not an earnings release or investor presentation, and does not fit any share issue, buyback, or management change category. It is a specialized regulatory announcement of contractual changes, so the most appropriate classification is a general Regulatory Filing (RNS).

사외이사의선임ㆍ해임또는중도퇴임에관한신고
Board/Management Information Classification · 92% confidence The document is a formal disclosure to the Financial Services Commission/Korea Exchange regarding the appointment, dismissal, and mid-term resignation of outside directors at Hana Materials Co., Ltd. It details the specific changes in board composition and profiles of the newly appointed outside director. This aligns with 'Board/Management Information' filings, which cover announcements of changes in the company's board of directors or senior management. Thus, the correct classification is MANG.
