Filing Released Lang Actions
단일판매ㆍ공급계약체결
Regulatory Filings Classification · 72% confidence The document is a disclosure of a single sale and supply contract concluded by the company, detailing contract amounts, parties, and payment terms. It is not a financial report (10-K, IR, ER), management discussion (MDA), nor related to dividends, share transactions, M&A, or capital markets transactions. It instead constitutes a general regulatory announcement of a material contract. As no more specific category applies, it falls under the fallback “Regulatory Filings” (RNS).

[기재정정]단일판매ㆍ공급계약체결
Regulatory Filings Classification · 80% confidence The document is a corporate disclosure in Korean titled “단일판매ㆍ공급계약체결” (Single Sales and Supply Contract Signing) with details of contract amount, counterparties, and correction notice. It is not a financing update (CAP), not an earnings release (ER), nor an annual or interim report. It is a standalone regulatory announcement of a material contract signing. Since there is no specific category for contract disclosures, it falls into the fallback “Regulatory Filings” category (RNS).

정기주주총회결과
Declaration of Voting Results & Voting Rights Announcements Classification · 90% confidence The document is a Korean-language announcement detailing the outcome of the regular shareholders’ (annual) general meeting held on 2026-03-27. It lists each agenda item (approval of financial statements, election of directors, auditor fees, etc.) alongside voting results and percentages. This matches the definition of a Declaration of Voting Results & Voting Rights Announcement (DVA).

임원ㆍ주요주주특정증권등소유상황보고서
Director's Dealing Classification · 90% confidence The document is titled “임원·주요주주 특정증권등 소유상황보고서,” which in Korean regulatory practice is the insider shareholding report filed by executives and major shareholders indicating their personal transactions and holdings of company securities. The text details an individual director’s name, relationship, share counts before and after transactions, changes in holdings, transaction dates, and method (gifts). This matches the definition of “Director’s Dealing” (insider trades by company officers). It is not a company buyback (POS), nor a general major shareholding threshold notice (MRQ), but specifically a personal insider transaction report. Therefore, it should be classified as DIRS.

It provides the auditor's opinion (unqualified/proper), key financial data (assets, liabilities, equity, revenue, operating profit), and specific financial ratios (capital impairment, loss ratios) for the fiscal year ending 2025-12-31. While it contains financial data, it is a standalone regulatory disclosure of the audit results rather than a full Annual Report (10-K) or a simple announcement of report publication (RPA). Therefore, it is classified as an Audit Report/Information. FY 2025
