Capital/Financing Update Classification · 1% confidence The document is an official announcement by the Board of 中达安股份有限公司 regarding the provision of a guarantee to its controlling subsidiary for a bank credit facility. This relates to the company's financing activities rather than a change in share capital, dividends, a legal proceeding, or an earnings report. Therefore it fits under the Capital/Financing Update category (CAP).

Audit Report / Information Classification · 1% confidence The document is a standalone special audit report (“专项审计报告”) issued by a certified public accounting firm (WUYIGE CPA) on a 2025-year non-operating funds occupation and related-party transactions summary table.

Therefore it fits the Audit Report / Information category.

2025年年度报告
Annual Report Classification · 1% confidence The document is the full 2025 Annual Report (“年度报告全文”) of 中达安股份有限公司, including complete financial statements, audit report, management discussion & analysis, governance, ESG and other comprehensive disclosures. It is the actual annual report itself (over 245,000 characters), not merely a notice of publication. This matches the definition of an Annual Report (10-K). FY 2025

2025年度内部控制评价报告
Governance Information Classification · 1% confidence The document is titled “2025年度内部控制评价报告” and constitutes a detailed internal‐control evaluation report covering governance structure, risk assessment, control activities, information flows, and supervisory mechanisms. It is not an announcement of another report, not a full annual or interim financial statement, nor a capital or M&A update. Instead, it describes the company’s internal rules, board oversight, risk control framework, and governance practices. Under the provided classification definitions, this falls under “Governance Information” (CGR).

关于2026年第一季度计提各项资产减值准备的公告
Regulatory Filings Classification · 1% confidence The document is a standalone regulatory announcement (“公告”) detailing the board’s approval and accounting policy for Q1 2026 asset impairment provisions, including amounts, methods, approvals, and file references. It is not a full interim/quarterly report (IR), nor an earnings release, management discussion, dividend notice, M&A, financing update, or other specific category. It is a general compliance filing that does not neatly fit any other specific type, making it a Regulatory Filing (RNS).

关于全资子公司业绩承诺完成情况及有关业绩补偿的公告
Regulatory Filings Classification · 1% confidence The document is an announcement by a listed company concerning the completion of performance commitments for its wholly‐owned subsidiary and the related cash compensation arrangements following an earlier acquisition. It does not present earnings data in the style of an earnings release, nor is it an annual or interim report, audit report, investor presentation, board change notice, dividend notice, share issue, or proxy solicitation. It is not announcing a merger proposal or takeover bid but is a follow-up disclosure required by stock exchange rules regarding performance guarantee compensation. It therefore falls into the catch-all “Regulatory Filings” category.
