2025年度可持续发展报告
Environmental & Social Information Classification · 100% confidence The document is titled "鼎龙股份 可持续发展报告 2025" which translates to "Dinglong Co., Ltd. Sustainability Report 2025." It covers extensive information on the company's environmental, social, and governance (ESG) performance, including governance structure, environmental management, social responsibility, stakeholder communication, and sustainability goals. The report references international standards such as GRI Standards and UN SDGs, and it is clearly a comprehensive sustainability report for the year 2025. There is no indication that this is an announcement or a brief summary; rather, it is a full report detailing ESG performance and management. This matches the definition of Environmental & Social Information (Code: SR).

2025年度内部控制自我评价报告
Audit Report / Information Classification · 95% confidence The document is titled '2025 年度内部控制评价报告' which translates to '2025 Annual Internal Control Evaluation Report'. It is issued by 湖北鼎龙控股股份有限公司 and dated March 27, 2026. The content details the company's internal control evaluation, including the scope, methodology, defect identification, and conclusions about the effectiveness of internal controls over financial and non-financial reporting. It includes detailed descriptions of organizational structure, risk areas, control procedures, and corrective actions. The document is comprehensive and contains substantive information about internal controls rather than just an announcement or certification. This fits the definition of an Audit Report / Information (AR), which includes standalone audit reports and applied accounting principles related to internal controls, excluding full annual reports. It is not an Annual Report (10-K) as it does not cover full financial performance or company activity broadly, nor is it a Regulatory Filing (RNS) or Report Publication Announcement (RPA) since it contains the full report text and analysis. Therefore, the appropriate classification is AR with high confidence. FY 2025

《未来三年（2026-2028年）股东分红回报规划》
Regulatory Filings Classification · 95% confidence The document is titled 'Future Three-Year (2026-2028) Shareholder Dividend Return Plan' and details the company's dividend policy and planning for the next three years. It discusses principles, conditions, proportions, decision mechanisms, and the planning cycle for shareholder dividends. The content is focused on dividend distribution strategy rather than announcing a specific dividend amount or payment date. The document length is 2702 characters, which is relatively short and reads like a policy or planning document rather than a report or announcement of a dividend payment. It is not an announcement of dividend amount (DIV) because it does not specify exact dividend amounts or payment dates for a particular period. Instead, it outlines a multi-year dividend planning framework. Therefore, the document best fits the category of a Regulatory Filing (RNS) as it is a regulatory disclosure of the company's dividend policy and planning, not a direct dividend announcement or financial report.

关于会计政策变更的公告
Regulatory Filings Classification · 95% confidence The document is an announcement from 湖北鼎龙控股股份有限公司 regarding a change in accounting policy. It details the reasons for the change, the previous and new accounting policies, the effective date, and the board's and audit committee's opinions on the change. The document is relatively short (1623 characters) and does not contain financial statements or substantive financial data. It is a formal disclosure about an accounting policy change rather than a full audit report or annual/interim report. This fits best under Regulatory Filings (RNS), which covers miscellaneous regulatory announcements that do not fit other categories.
2026-03-26 Chinese
关于暂不召开股东会的公告
Report Publication Announcement Classification · 95% confidence The document is a short announcement (490 characters) from 湖北鼎龙控股股份有限公司 stating that the company will temporarily not hold the annual shareholders meeting to approve the 2025 annual report and related matters. It references that the 2025 annual report has already been disclosed on the official information disclosure website. The document does not contain the annual report itself or detailed financial data, but rather informs about the postponement of the shareholders meeting. According to the 'Menu vs Meal' rule, this is an announcement about a report or meeting, not the report itself. Therefore, it fits best under Report Publication Announcement (RPA).
2026-03-26 Chinese
第六届董事会第九次会议决议公告
AGM Information Classification · 95% confidence The document is a detailed announcement of the resolutions passed at the 9th meeting of the 6th Board of Directors of 湖北鼎龙控股股份有限公司. It includes approvals of the 2025 Annual Report and its summary, the 2025 Board work report, the 2025 Supervisory Board report, the 2025 General Manager work report, financial statements for 2025, internal control self-evaluation report, and other related reports. It also discusses proposals related to remuneration, capital changes, financing, and other governance matters. The document states that the full 2025 Annual Report and related reports are published on the regulatory website and will be submitted to the 2025 Annual General Meeting for approval. The document itself is a formal announcement of the board meeting resolutions rather than the full annual report or financial statements. The length is about 7,570 characters, which is relatively short for a full annual report. Therefore, this document is best classified as an AGM Information document (AGM-R) because it contains materials and resolutions shared during the board meeting in preparation for the AGM, but it is not the full annual report itself.
