사업보고서 (2025.12)
Audit Report / Information Classification · 1% confidence The document is a comprehensive 'Consolidated Audit Report' (연결감사보고서) for Duksan Neolux Co., Ltd. It includes the independent auditor's report, consolidated financial statements (balance sheet, income statement, statement of changes in equity, cash flow statement), and detailed notes.
