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 details the board's activities, meetings, governance, financial performance summary, and plans for the next year. It includes comprehensive information about the board's operations, governance, internal controls, and strategic outlook. The document is not a full annual report but specifically focuses on the board's work and governance aspects for the year 2025. It is not a short announcement or a certification but a detailed report on board and management information. Therefore, the most appropriate classification is 'Board/Management Information' (MANG). The document length (3885 characters) is somewhat short but contains substantive content about board activities rather than just an announcement or summary, so it is not an RPA or RNS.

内部控制审计报告
Audit Report / Information Classification · 95% confidence The document is titled '内部控制审计报告' which translates to 'Internal Control Audit Report'. It is issued by a certified public accounting firm (ShineWing) and addresses the effectiveness of internal control over financial reporting for the fiscal year ending December 31, 2025. The content includes auditor responsibilities, company responsibilities, audit opinions on internal control, and mentions specific internal control deficiencies and remediation. The document length is 4125 characters, which is relatively short but contains substantive audit opinion and internal control evaluation, not just an announcement or certification. This matches the definition of an Audit Report / Information (AR), which includes standalone audit reports and applied accounting principles related to internal control audits, distinct from full Annual Reports (10-K) or mere announcements (RPA). Therefore, the document is best classified as an Audit Report / Information (AR). FY 2025

The document length is 4796 characters, which is sufficient to contain substantive audit information rather than just a brief announcement. Hence, the classification is AR with high confidence.

2025年半年度报告（更正公告）
Regulatory Filings Classification · 95% confidence The document is titled as a "2025年半年度报告更正公告" which translates to "2025 Semi-Annual Report Correction Announcement." It references the original 2025 semi-annual report and details corrections made due to accounting errors. The document is relatively short (1100 characters) and primarily announces corrections to a previously published interim report rather than containing the full financial statements or substantive financial data itself. It also states that the corrected report will be disclosed on the exchange website alongside this announcement. According to the MENU VS MEAL RULE, this is an announcement about a report correction, not the report itself. Therefore, the document should be classified as a Regulatory Filing (RNS) rather than an Interim Report (IR).

2024年年度报告摘要（更正公告）
Regulatory Filings Classification · 95% confidence The document is titled as a correction announcement for the 2024 Annual Report Summary of Kunming University of Science and Technology Hengda Technology Co., Ltd. It references the original 2024 Annual Report Summary and details corrections due to prior accounting errors. The document is relatively short (1104 characters) and primarily announces corrections and references other announcements where the corrected report and detailed corrections are published. It does not contain the full annual report or substantive financial data itself but serves as a correction notice and announcement. According to the 'Menu vs Meal' rule, such a correction announcement that points to the actual report elsewhere should be classified as a Regulatory Filing (RNS) rather than the Annual Report (10-K) itself.
