Filing Released Lang Actions
[기재정정]최대주주변경을수반하는주식담보제공계약체결
Regulatory Filings Classification · 85% confidence The document is a regulatory disclosure of a “stock pledge contract involving a change of controlling shareholder,” filed on the KRX disclosure system (kind.krx.co.kr). It details the terms of share collateral provisions by the major shareholder and amendments thereto. This is not an earnings release, financial report, management presentation, nor a share issue or buyback by the company. It is a general compliance/transaction notice on the exchange, so it falls into the fallback category Regulatory Filings (RNS).

주식등의대량보유상황보고서(일반)
Major Shareholding Notification Classification · 92% confidence The document is a detailed “주식등의 대량보유상황보고서” (large shareholding status report) filed by a major shareholder under Korean capital markets law. It provides ownership percentages, changes, and contractual details for the filing entity and its affiliates. This matches the definition of a Major Shareholding Notification (code MRQ).

[기재정정]최대주주변경을수반하는주식담보제공계약체결
Regulatory Filings Classification · 22% confidence The document is a KRX disclosure announcing the terms of a stock pledge by the largest shareholder (share collateral agreements), including corrected details on share counts, debt amounts and contract terms. It is not a standalone financial report (10-K, IR), not related to dividends or AGM materials, nor an M&A or share issuance. It is a general regulatory announcement of a shareholder collateral transaction. As it does not fit any more specific category, it falls under Regulatory Filings (RNS).

[기재정정]최대주주변경을수반하는주식담보제공계약체결
Regulatory Filings Classification · 78% confidence The document is an official regulatory disclosure (Korean KRX ‘정정신고(보고)’) detailing a correction to the previously filed share‐pledge contract by the controlling shareholder. It contains no financial statements or substantive analysis, nor is it an AGM, earnings, management report, or share issuance. It’s a routine regulatory announcement for a collateral arrangement and thus falls into the general “Regulatory Filings” category (RNS).
2026-05-29 Korean
주식등의대량보유상황보고서(일반)
Major Shareholding Notification Classification · 95% confidence The document is a statutory ‘주식등의 대량보유상황보고서’ filed under Korean capital markets law, detailing the number and percentage of shares held by a major shareholder and related parties, with pre- and post-change positions and transaction details. This clearly matches a Major Shareholding Notification rather than a financial report or earnings release.
2026-05-22 Korean
[기재정정]최대주주변경을수반하는주식담보제공계약체결
Regulatory Filings Classification · 55% confidence The document is a regulatory disclosure of a stock collateral (pledge) agreement by the company’s major shareholder (전동규) and a correction report updating pledge amounts, debt figures, and share ratios. It is neither an earnings release nor a management report, not a dividend notice, M&A activity, or share issue notice. It does not present full financial statements or request votes. It is a routine regulatory announcement under Korean exchange rules that does not fit other specific categories, so it defaults to the General Regulatory Filings category (RNS).
