2025年年度报告摘要
Annual Report Classification · 95% confidence The document is titled as "2025 年年度报告摘要" which translates to "2025 Annual Report Summary". It contains detailed financial data for the year 2025, including main accounting data, financial indicators, quarterly data, shareholder information, and business descriptions. The document is over 9,000 characters, indicating it is a substantive report rather than a brief announcement. It includes audited financial statements with an auditor's opinion, detailed business operations, and financial performance metrics. The presence of comprehensive financial and operational information for the full fiscal year aligns with the definition of an Annual Report (10-K). There is no indication that this is merely an announcement or a certification document, nor is it a quarterly or interim report. Therefore, the document should be classified as an Annual Report (10-K). FY 2025

2025年度内部控制自我评价报告
Audit Report / Information Classification · 95% confidence The document is titled as an "Internal Control Self-Evaluation Report" for the year 2025 by 实朴检测技术（上海）股份有限公司. It discusses the company's internal control evaluation, including governance structure, risk assessment, control activities, information and communication, and internal supervision. It includes detailed descriptions of internal control policies, defect recognition standards, and evaluation conclusions. The document is comprehensive and contains substantive content related to internal control evaluation rather than just an announcement or summary. It is not a financial report like an Annual Report (10-K) or Interim Report (IR), nor is it an audit report (AR) in the traditional sense, but rather a detailed internal control evaluation report. Given the content and nature, it fits best under Audit Report / Information (AR), which includes standalone audit reports and internal control evaluation results. The document length (8126 characters) supports it being a full report rather than a brief announcement or certification. Therefore, the classification is AR with high confidence. FY 2025

关于2025年年度计提信用减值准备及资产减值的公告
Regulatory Filings Classification · 95% confidence The document is an announcement from a company about the 2025 annual provision for credit impairment and asset impairment. It details the amounts, accounting standards, methods for impairment recognition, and the impact on profits and equity. The document is titled as an announcement and includes a statement that the impairment provision has been audited by an accounting firm. It does not contain a full annual report or comprehensive financial statements but focuses on a specific accounting provision update. The length is about 5116 characters, which is relatively short and focused. This fits best with a Regulatory Filing (RNS) as it is a regulatory announcement about impairment provisions rather than a full financial report or audit report. It is not a full Annual Report (10-K), Audit Report (AR), or Interim Report (IR). Therefore, the classification is Regulatory Filings (RNS) with high confidence.

It details the amount of funds raised, their usage, management, and changes in investment projects related to the raised capital. It references regulatory rules related to fundraising and includes detailed tables on fund usage and project changes. The document is comprehensive and contains substantive financial data related to capital raised and its deployment, not just an announcement or summary. Therefore, it fits the category of a Capital/Financing Update (CAP) which covers updates on company fundraising, financing activities, or capital structure changes.

It details the audit firm's background, the procedures followed for reappointment, and the committee's oversight activities during the audit process. It does not contain the full audit report or financial statements but rather a supervisory report on the audit firm's performance and independence. The document length is 1815 characters, which is relatively short and focused on audit oversight rather than the full annual report or audit report itself. This fits the definition of an Audit Report / Information (AR) filing, which includes standalone audit reports and information about audit procedures and results of internal oversight, excluding the full Annual Report. Therefore, the correct classification is AR with high confidence. FY 2025
