关于续聘会计师事务所的公告
Audit Report / Information Classification · 95% confidence The document is an announcement regarding the reappointment of an accounting firm (auditor) for the company's 2026 financial report and internal control audit. It details the auditor's background, qualifications, audit fees, and the approval process by the board and audit committee. There is no actual financial data or audit report included, only information about the auditor appointment and related procedures. The document length is 3288 characters, which is relatively short and consistent with an announcement rather than a full audit report. Therefore, this document is best classified as an Audit Report / Information (AR) type, as it relates to audit information but is not the full annual report or audit report itself. However, given the short length and nature as an announcement of auditor reappointment, it aligns more closely with Audit Report / Information (AR) rather than a full Annual Report (10-K) or Regulatory Filing (RNS).

关于举办2025年年度业绩说明会的公告
Investor Presentation Classification · 95% confidence The document is an announcement about the scheduling and details of the 2025 annual performance explanation meeting (业绩说明会) for 实朴检测技术（上海）股份有限公司. It references that the 2025 Annual Report has already been disclosed on April 23, 2026, and this meeting is intended to provide investors with further explanation and interaction regarding the annual results. The document does not contain the actual annual report or financial data but rather details about the upcoming investor meeting to discuss the annual results. The document length is short (1308 characters) and it is clearly an announcement of a meeting related to the annual report, not the report itself. Therefore, it fits the category of an Investor Presentation (IP) or possibly an AGM Information (AGM-R). However, since it is specifically an annual performance explanation meeting (业绩说明会), which is typically an investor presentation focused on financials and strategy, the best fit is Investor Presentation (IP).

实朴检测技术（上海）股份有限公司募集资金存放、管理与实际使用情况的鉴证报告
Audit Report / Information Classification · 95% confidence The document is a detailed verification report by Zhongxinghua Certified Public Accountants LLP on the use, management, and storage of funds raised by 实朴检测技术(上海)股份有限公司 (ShiPu Testing Technology (Shanghai) Co., Ltd.) for the fiscal year ending December 31, 2025. It references compliance with Chinese securities regulations and Shenzhen Stock Exchange guidelines regarding fundraising and fund management. The report includes detailed financial data on the amount raised, fees, usage, balances, and changes in fundraising projects. The presence of an auditor's verification opinion and the focus on fundraising usage and management indicates this is a standalone audit-related report specifically about fundraising compliance and fund usage, not a full annual report or earnings release. Therefore, it fits the definition of an Audit Report / Information (AR). The document length (15,000 characters) and detailed content confirm it is the report itself, not just an announcement or certification letter. FY 2025

2025年度非经营性资金占用及其他关联资金往来情况汇总表
Regulatory Filings Classification · 85% confidence The document is a detailed tabular summary of non-operating fund occupation and other related party fund transactions for the year 2025, including balances, amounts, and interest related to these transactions. It is a financial disclosure related to related-party transactions and fund usage, typically part of a company's financial or regulatory reporting. The document is 8626 characters long, which is substantial and contains detailed financial data, not just an announcement or certification. It does not appear to be a full annual or interim report but rather a specific financial disclosure related to related-party transactions and fund usage. Such disclosures are often part of regulatory filings or supplementary financial information but given the detailed financial data and the nature of the content, it fits best under Regulatory Filings (RNS) as it does not match the definitions of other more specific report types like Annual Report, Interim Report, or Audit Report. It is not a report publication announcement since it contains the actual data, not just a notice of availability.

董事会对独立董事独立性自查情况的专项报告
Governance Information Classification · 95% confidence The document is a special report from the board regarding the independence of independent directors, referencing regulatory guidelines and internal compliance. It is not an annual report, audit report, or financial statement. It is a governance-related disclosure about board members' independence, which fits the category of Governance Information (CGR). The document is short and focused on governance compliance rather than financial or operational data.

2025年度独立董事述职报告-李金桂
Board/Management Information Classification · 95% confidence The document is titled as an "Independent Director's Work Report" for the year 2025 of a company. It details the independent director's attendance at board and shareholder meetings, participation in committees, supervision of financial reports and audits, involvement in governance and compliance matters, and overall performance evaluation. The content focuses on the independent director's duties and activities during the year, rather than presenting financial statements or audit opinions themselves. It is a detailed report on board/management information, specifically about the independent director's role and activities. It is not an annual report, audit report, earnings release, or any other financial report type. It is also not a short announcement or certification but a substantive report on management/board activities. Therefore, the most appropriate classification is Board/Management Information (MANG). The document length (5372 characters) supports it being a full report rather than a brief announcement.
