Major Shareholding Notification Classification · 1% confidence The document is titled “주식등의 대량보유상황보고서(약식)” (Report on Large Shareholdings) and provides detailed disclosures of stock holdings, changes in share count and ownership percentages by a professional investor.

[기재정정]단일판매ㆍ공급계약체결
Regulatory Filings Classification · 1% confidence The document is a Korean corporate filing announcing and amending a ‘single sales and supply contract’ (단일판매ㆍ공급계약체결) including contract details, counterpart, amounts, and a corrected end date. It is not a financial report (e.g., annual or interim), not an earnings release or presentation, nor a board/management change, share transaction, dividend notice, or other specified category. No specific category for a material contract announcement exists, so it falls into the fallback category for miscellaneous regulatory announcements.

기업가치제고계획(자율공시)
Regulatory Filings Classification · 1% confidence The document is a voluntary regulatory disclosure (“자율공시”) by Semyung Electric outlining a corporate value enhancement plan. It is neither an annual or interim financial report, nor an investor presentation, earnings release, dividend notice, or management change announcement. It is a standalone plan document that does not fit any other specific category, so it falls into the general regulatory filings fallback category.

[기재정정]단일판매ㆍ공급계약체결
Regulatory Filings Classification · 0% confidence The document is a Korean regulatory disclosure detailing a single sales and supply contract conclusion (and its subsequent correction). It provides contract terms, amounts and parties, not financial results, management changes, dividends or share transactions. There is no indication it is an earnings release, annual or interim report, proxy statement, M&A notice or insider dealing. This type of contract announcement does not match any more specific category, so it falls into the general Regulatory Filings fallback category.

[기재정정]단일판매ㆍ공급계약체결
Regulatory Filings Classification · 1% confidence The document is a Korean stock exchange disclosure titled “단일판매ㆍ공급계약체결” (execution of a single sales and supply contract). It includes contract terms, amounts, counterparties, and a correction notice for revised dates. This is neither a financial report (10-K, IR), earnings release, nor a financing/capital change notice. It is a routine regulatory announcement of a new contract award. None of the more specific categories (e.g., CAP, TAR, DIRS) apply, so the correct classification is the fallback Regulatory Filings (RNS).
