Filing Released Lang Actions
증권발행결과(자율공시)
Share Issue/Capital Change Classification · 90% confidence The document is a voluntary regulatory disclosure in Korean titled “증권 발행결과(자율공시)” (securities issuance results). It details the type of security (private convertible bonds), issuance method, issuance amounts, board resolution dates, payment date, and listing plans. This is an announcement of a capital instrument issuance, which falls squarely under share issue/capital change activities. Hence the correct category is Share Issue/Capital Change (SHA).
2026-05-21 Korean
분기보고서 (2026.03)
Interim / Quarterly Report Classification · 95% confidence The document is titled "분기보고서" (Quarterly Report) for the 27th fiscal period covering 2026-01-01 to 2026-03-31. It contains detailed sections typical of an interim/quarterly report: company overview, business content, summary and full financial statements with notes, management’s analysis, auditor’s opinion, and other disclosures. It clearly includes substantive financial data for a period shorter than a full fiscal year. Therefore, it matches the Interim/Quarterly Report category. Q1 2026
2026-05-15 Korean
주요사항보고서(전환사채권발행결정)
Capital/Financing Update Classification · 89% confidence The document is a major event disclosure (“주요사항보고서”) filed with the Financial Services Commission/Korea Exchange announcing the decision to issue convertible bonds (전환사채권). It details bond terms, conversion mechanics, options and use of proceeds. This is a financing activity (issuance of debt convertible to equity) rather than an earnings release or management discussion. It is not merely a publication announcement of a report (it contains substantive transaction details). The proper category is a capital/financing update (CAP).
2026-05-13 Korean
주식등의대량보유상황보고서(약식)
Major Shareholding Notification Classification · 94% 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.
2026-04-22 Korean
[기재정정]전환청구권행사
Share Issue/Capital Change Classification · 90% 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 · 85% 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).
