Filing Released Lang Actions
주식등의대량보유상황보고서(약식)
Major Shareholding Notification Classification · 1% confidence The document is a “주식등의 대량보유상황보고서(약식)” filed under Korea’s Capital Markets Act, detailing changes in shareholding levels, number of shares held before and after, percentage thresholds (e.g., 1%), reporting reasons, and insider/related party breakdown. This matches a Major Shareholding Notification (MRQ) rather than an earnings release, annual report, or other category.

[기재정정]전환청구권행사
Share Issue/Capital Change Classification · 1% confidence The document is a regulatory disclosure detailing the exercise of convertible bond conversion rights, including the number of shares issued, listing dates, and corrections to prior filings. This constitutes a corporate action resulting in new share issuance and thus represents a share issue/capital change announcement. Hence, it fits the Share Issue/Capital Change category (SHA).
2026-04-16 Korean
전환사채(해외전환사채포함)발행후만기전사채취득
Capital/Financing Update Classification · 1% confidence The document is a corporate disclosure detailing the company’s acquisition of its own issued convertible bonds prior to maturity (early redemption request by bondholder), including amounts, dates, funding source, and method. This constitutes an update on the company’s financing activities and a change in its capital structure (debt redemption). It is not a full report (like Annual or Interim), nor a simple announcement of report publication. It specifically concerns financing/capital structure, so it fits the Capital/Financing Update category (CAP).
2026-04-13 Korean
단일판매ㆍ공급계약체결
Regulatory Filings Classification · 1% confidence The document is a public announcement in Korean of a ‘single sale and supply contract’ (단일판매ㆍ공급계약체결) with details of the counterparty, contract amount, period, and terms. This is an operational contract announcement and not a financial report (e.g., 10-K, quarterly IR), not a dividend, insider transaction, financing update, M&A, or governance change. There is no indication of an investor presentation, earnings release, or supplementary financial spreadsheet. It therefore falls into the general regulatory announcements bucket. As no more specific category applies, it should be classified as a Regulatory Filing (RNS).
2026-04-09 Korean
전환청구권행사
Share Issue/Capital Change Classification · 1% confidence The document is a public disclosure in Korean detailing the exercise of conversion rights on a convertible bond, including the number of shares to be newly issued, the total issued shares, conversion price, and listing dates. This activity constitutes a change in share capital due to the issuance of shares upon bond conversion. According to the filing definitions, announcements regarding new share issues or capital structure changes fall under Share Issue/Capital Change (Code: SHA).
2026-04-08 Korean
대표이사변경
Board/Management Information Classification · 1% confidence The document is an official announcement detailing changes in the company’s representative directors, including names before and after, reasons for change, board resolution date, attendance by directors and auditors, and biographies of the newly appointed directors. This clearly corresponds to a Board/Management Information filing.
