It is not a financial report (no audited statements), not a dividend, not management change, nor a capital-raising update—it is a regulatory announcement of a contract. There is no specific category for contract awards, so under the fallback it belongs to Regulatory Filings (RNS).

주식등의대량보유상황보고서(일반)
Major Shareholding Notification Classification · 100% confidence The document is titled '주식등의 대량보유상황보고서(일반)' which translates to 'Report on Large Shareholding Status (General)'. It contains detailed information about the number of shares held by a major shareholder and related parties, changes in shareholding, and related contracts such as stock pledge agreements. The document references specific dates and shareholding percentages, and it is clearly a notification of large shareholding positions and changes thereof. This matches the definition of a Major Shareholding Notification (MRQ), which involves notification of changes in significant share ownership levels. The document is about reporting large shareholdings and changes, not about financial results, management changes, or other categories. The length of the document (8689 characters) and the detailed data confirm it is the report itself, not just an announcement of a report. Therefore, the correct classification is MRQ with high confidence.
