内部控制评价报告
Audit Report / Information Classification · 95% confidence The document is titled "内部控制评价报告" which translates to "Internal Control Evaluation Report." It is issued by the company's board and discusses the evaluation of the company's internal control effectiveness as of December 31, 2025. The content includes detailed descriptions of internal control systems, risk assessments, control activities, information and communication, and internal supervision. It also includes standards for identifying internal control deficiencies and their rectification status. The document is 8426 characters long, which is substantial and contains detailed substantive content rather than a brief announcement or certification. It is not a financial statement report like an Annual Report (10-K) or Interim Report (IR), nor is it an audit report or a regulatory filing.

2025年度董事会工作报告
Board/Management Information Classification · 95% confidence The document is titled '2025年度董事会工作报告' which translates to '2025 Annual Board of Directors Work Report'. It contains detailed information about the board's activities, governance, meetings, and plans for the next year. It includes financial performance summaries but does not present full financial statements or comprehensive financial data typical of an Annual Report (10-K) or Interim Report (IR). The document focuses on the board's work, governance, and management activities rather than financial results alone. It is not a short announcement or a certification but a substantive report on board and management activities for the year. Therefore, it fits best under the category 'Board/Management Information (MANG)'. The document length (5961 characters) supports it being a full report rather than a brief announcement.

2025年度审计报告
Audit Report / Information Classification · 95% confidence The document is titled as the "2025年度审计报告" (2025 Annual Audit Report) for 三门三友科技股份有限公司. It contains detailed audit opinions, audit basis, key audit matters, and extensive financial statements including consolidated balance sheets, income statements, cash flow statements, and equity changes. The presence of an auditor's opinion, detailed financial statements, and notes indicates this is a full audit report rather than just an announcement or certification. The document length is substantial (15,000 characters), and it includes comprehensive financial data and analysis for the fiscal year 2025. Therefore, it fits the category of an Audit Report / Information (AR) rather than a full Annual Report (10-K) because it is specifically the audit report and related financial statements, not the entire annual report including management discussion and other sections. Hence, the classification is AR with high confidence. FY 2025
