开源证券股份有限公司关于北京鼎汉技术集团股份有限公司2025年度内部控制评价报告的核查意见
Audit Report / Information Classification · 1% confidence The document is a formal “核查意见” (review opinion) by the sponsor (开源证券) on the company’s 2025年度内部控制评价报告, containing audit opinions and internal control evaluation results. This is a standalone audit/review report related to internal controls (not a full annual report), fitting the Audit Report / Information category (AR).

2025年年度报告披露提示性公告
Report Publication Announcement Classification · 1% confidence The document is a brief announcement (267 characters) stating that the company’s 2025 Annual Report and summary have been published on the official disclosure website and directs investors to review it. This fits the definition of a Report Publication Announcement (RPA) under the “menu vs meal” rule, as it does not contain the report itself but merely announces its availability.
2026-04-13 Chinese
2025年度董事会工作报告
Governance Information Classification · 1% confidence The document is a standalone Board of Directors’ Work Report (“董事会工作报告”) summarizing board activities, committee functions, governance practices, information disclosure, and investor relations for the 2025 fiscal year. It is not an earnings release, proxy statement, or management change notice, nor is it the full annual report or financial statements. Instead, it details the company’s internal governance structure and board oversight responsibilities, matching the Governance Information category.

独立董事述职报告（罗顺均）
Governance Information Classification · 1% confidence The document is a mandatory annual ‘述职报告’ (performance report) by the company’s independent director summarizing attendance, duties, governance oversight, and key focus areas during the 2025 reporting period. It is not a full annual report, earnings release, share transaction notice, or capital announcement. This fits under corporate governance information—detailing board oversight, committee participation, and governance practices—so it aligns with the Governance Information category (CGR).

2025年度内部控制评价报告
Audit Report / Information Classification · 1% confidence The document is a standalone internal control evaluation report prepared by the company assessing the effectiveness of its internal controls over financial and non-financial reporting. It is not an annual report or earnings release, nor a change in management or financing notice. It aligns with “Audit Report / Information” as it presents the results of an internal control audit/evaluation under regulatory control standards, rather than full financial statements or a simple notice. Therefore, it fits the AR category.

董事、高级管理人员薪酬管理制度（2026年4月）
