Audit Report / Information Classification · 1% confidence The document is a “专项报告” (special report) prepared and signed by a certified public accounting firm (BDO Lixin) on non-operating fund occupation and other related-party transactions for the year 2025. It is a standalone audit report supplementing the audited financial statements, containing audit findings, report numbers, auditor signatures, and detailed tables, not the full annual report itself or simply an announcement. This fits the definition of an Audit Report/Information (AR).

独立董事2025年度述职报告（管宏斌）
Governance Information Classification · 1% confidence The document is an independent director’s 2025 annual duty/performance report (“述职报告”) describing board meeting attendance, committee work, internal control oversight and governance actions. It is not announcing a board change (MANG), not a financial or audit report, not a proxy statement or dividend notice, nor a summary presentation. It is a governance‐related report by a board member on corporate governance activities, so it most closely fits the Governance Information category.
2026-04-24 Chinese
2025年度内部控制审计报告
Audit Report / Information Classification · 1% confidence The document is an “内部控制审计报告” (Internal Control Audit Report) for the year ended December 31, 2025, issued by BDO China Shu Lun Pan Certified Public Accountants. It is a standalone audit report focusing on the effectiveness of internal controls over financial reporting, not a full annual or interim financial report. According to the definitions, this falls under a standalone Audit Report / Information (Code: AR).
2026-04-24 Chinese
2025年度内部控制自我评价报告
Regulatory Filings Classification · 1% confidence The document is a 2025年度内部控制自我评价报告 (Internal Control Self-Evaluation Report) issued by the company’s board and audit committee. It is not an Annual Report (10-K), Quarterly/Interim Report (IR), Earnings Release (ER), audit opinion from external auditors (AR), nor any of the other listed categories (e.g., Board changes, M&A, dividends, share issues). It is the full internal control self-evaluation document rather than a short announcement of publication. This type of mandatory regulatory filing in Chinese markets that doesn’t fit the specific definitions is therefore classified under the fallback category “Regulatory Filings” (RNS).
2026-04-24 Chinese

Audit Report / Information Classification · 1% confidence The document is a standalone assurance (audit) report by BDO China (立信会计师事务所) on 三变科技股份有限公司’s 2025年度募集资金存放、管理与使用情况专项报告. It is not the full annual report but a special-purpose audit on proceeds storage, management and use, consistent with the definition of an Audit Report / Information. Therefore, it should be classified as AR.
