Filing Released Lang Actions
[기재정정]타인에대한채무보증결정
Regulatory Filings Classification · 75% confidence The document is a corporate disclosure under Korean capital markets law announcing a decision by LB Semicon to provide a debt guarantee (“타인에 대한 채무보증 결정”) for its subsidiary, including corrected details on guarantee amounts, periods, and related party information. It is not a full financial report (Annual or Interim), earnings release, or capital-raising notice, nor is it a voting result, dividend notice, or share transaction. It is a standalone regulatory announcement of a contingent liability decision, which does not match any of the more specific categories and thus falls into the fallback category of general regulatory filings.
2026-06-09 Korean
[기재정정]증권신고서(지분증권)
Share Issue/Capital Change Classification · 90% confidence The document is a Korean-language securities registration statement (“증권신고서(지분증권)”) for an equity issuance by LB Semicon, including a formal correction (“정정신고”) to the initial filing. It is not a financial report (10-K, IR), nor an earnings release, nor a board/management change notice. Instead, it details a new share offering (equity issuance) and capital-raising process. Under the defined categories, this fits “Share Issue/Capital Change” (SHA), which covers announcements and filings related to new share issues or capital structure changes.
2026-06-01 Korean
주식등의대량보유상황보고서(일반)
Major Shareholding Notification Classification · 90% confidence The document is a Korean "주식등의 대량보유상황보고서(일반)" form filed under the Capital Markets Act, detailing an individual and related parties’ large shareholding positions, contract terms, and changes. This matches the definition of a Major Shareholding Notification, not an earnings release or management report. It is the actual report of holdings rather than an announcement. Therefore, the correct category is MRQ.
2026-05-18 Korean
주요사항보고서(유상증자결정)
Share Issue/Capital Change Classification · 94% confidence The document is a mandatory major event report filed with the stock exchange and financial regulator announcing the board decision on a paid-in capital increase (issuance of new shares), detailing share numbers, pricing, allocation, subscription dates, and other terms. This is a direct announcement of a new share issue, fitting the Share Issue/Capital Change category rather than a general financial report or earnings release.
2026-05-15 Korean
증권신고서(지분증권)
Share Issue/Capital Change Classification · 93% confidence The document is a comprehensive “증권신고서(지분증권)” – a securities registration statement (prospectus) for issuance of 12,000,000 shares, detailing the offering, risk factors, business overview, and capital raising plan. This clearly constitutes a share issue/capital change filing rather than an announcement of an earnings release, management change, or proxy solicitation. As such, it falls under Share Issue/Capital Change (SHA).
2026-05-15 Korean
[첨부추가]분기보고서 (2026.03)
Interim / Quarterly Report Classification · 95% confidence The document is titled “분기보고서” (Quarterly Report) covering the period 2026-01-01 to 2026-03-31 (1st quarter of fiscal year 27). It contains detailed financial statements, business overview, segment performance, risk management and other substantive financial data. This matches an Interim/Quarterly Report rather than an announcement or summary. Q1 2026
