단일판매ㆍ공급계약체결(자율공시)
Regulatory Filings Classification · 85% confidence The document is a self-disclosure of a single large sales/supply contract (자율공시) by a Korean company, detailing contract parties, amounts, and terms. It is not an earnings release, management discussion, financing update, or any specialized report category; rather it is a general regulatory announcement of a contract. Therefore it falls under the fallback “Regulatory Filings” category (RNS).

단일판매ㆍ공급계약체결(자율공시)
Regulatory Filings Classification · 91% confidence The document is a voluntary regulatory disclosure (‘자율공시’) by a Korean company announcing the signing of a single sales and supply contract, including contract terms, counterpart, and amounts. It is not an annual or interim report, earnings release, board change, share transaction, financing notice, or any other specific category. Therefore, it falls under the general “Regulatory Filings” fallback category (RNS).

분기보고서 (2026.03)
Interim / Quarterly Report Classification · 95% confidence The document is titled “분기보고서” (Quarterly Report) for the 29th fiscal year, 1st quarter (2026.01.01–2026.03.31), contains comprehensive company overview, business content, and actual financial details. It is not a mere announcement or attachment notice but the full interim/quarterly filing itself. Therefore, it matches the definition of an Interim / Quarterly Report. Q1 2026

[기재정정]단일판매ㆍ공급계약체결(자율공시)
Regulatory Filings Classification · 80% confidence The document is a voluntary disclosure of a single sale and supply contract (‘단일판매ㆍ공급계약 체결’) by the company, providing contract details (counterparty, amount, period). It is not a financial report, management change, dividends notice, share issue, or earnings release, but rather a regulatory disclosure of a business contract. This falls under miscellaneous regulatory filings that do not match the specific categories, so it is classified as RNS.

소속부변경
Regulatory Filings Classification · 95% confidence The document is a short announcement about a change in the company's department affiliation from '중견기업부' (Mid-sized Enterprise Division) to '벤처기업부' (Venture Enterprise Division). It includes the company name, the change details, the reason for change, and the effective date. There is no financial data, no mention of reports, no regulatory certifications, or voting results. This type of announcement is a regulatory update about company classification or status change, which fits best under Regulatory Filings (RNS) as it does not fit other specific categories.

[기재정정]단일판매ㆍ공급계약체결(자율공시)
Regulatory Filings Classification · 80% confidence The document is a Korean voluntary disclosure (“자율공시”) for the signing and subsequent amendment of a single large sales and supply contract (단일판매·공급계약 체결). It details the contract amount, counterparties, and contract terms. This is neither a financial report (10-K, IR), earnings release, dividend notice, management change, M&A, nor financing announcement. It is a standard regulatory announcement about a contract, so it falls into the fallback category of general regulatory filings (RNS).
