주식등의대량보유상황보고서(약식)
Major Shareholding Notification Classification · 90% confidence The document is a Korean “주식등의 대량보유상황보고서(약식)” – a large shareholding status report indicating changes in shareholdings and crossing significant thresholds by an investor (Neo-solutions Inc.). It details the number of shares held before and after, percentage changes, reporting dates, and reasons for acquisition. This matches the definition of a Major Shareholding Notification (Code: MRQ).

주식등의대량보유상황보고서(일반)
Major Shareholding Notification Classification · 90% confidence The document is a detailed “주식등의 대량보유상황보고서(일반)” (Report on Large Shareholding Status) filed under Korea’s Capital Markets Act. It enumerates the reporter, special related parties, share counts, percentages, changes, contracts, and major holdings over threshold. This corresponds to a Major Shareholding Notification rather than an earnings, governance, or annual report. Thus, it fits the “Major Shareholding Notification” category (Code: MRQ).

[기재정정]최대주주변경을수반하는주식담보제공계약체결
Capital/Financing Update Classification · 70% confidence The document is a regulatory disclosure detailing a stock pledge contract by the controlling shareholder to secure financing (bridge loans) in connection with a change in control. It is not a report (e.g., annual or interim), not an insider trade per se, nor a dividend or voting announcement. It specifically concerns a financing arrangement secured by share collateral, which falls under “Capital/Financing Update.” Therefore, the closest match is CAP.
