Regulatory Filings Classification · 1% confidence The document is a corporate announcement by Kaishan Group Co., Ltd. concerning the reappointment of its external audit firm for the 2026 fiscal year. It is not an actual audit report (AR), nor is it an annual or interim financial report (10-K/IR), earnings release (ER), or other specified category. It also does not announce dividend, share issue, M&A activity, board changes, or proxy materials.

Governance Information Classification · 1% confidence The document is an annual performance report (‘述职报告’) by an independent director describing governance activities, board and committee attendance, compliance with listing rules, communication with auditors and shareholders, and other corporate governance work. It is not an announcement of a report, nor a change in board composition, nor a financial report on results. It falls under Governance Information (CGR) as it details governance practices and the independent director’s role in board governance.

2025年度内部控制审计报告
Audit Report / Information Classification · 1% confidence The document is an internal control audit report issued by a certified public accounting firm for Kaishan Group’s financial report internal controls as of December 31, 2025. It contains the auditor’s responsibilities, opinion on internal control effectiveness, and supporting attachments such as the firm’s practice license. It is a standalone audit report rather than an annual or interim financial statement, earnings release, or mere announcement of a report. Therefore, it fits the “Audit Report / Information” category.

Governance Information Classification · 1% confidence The document is the company’s “信息披露管理制度” (Information Disclosure Management System), an internal governance manual outlining disclosure principles, responsibilities, procedures, committees, and internal rules. It is not a financial report, announcement of results, or a regulatory filing per se, but rather a governance document describing internal rules and practices. This aligns with the Governance Information category (CGR).

Regulatory Filings Classification · 1% confidence The document is a regulatory announcement by a listed Chinese company disclosing the forecasted cap and details of its 2026 daily related-party transactions, including board approvals, independent directors’ opinions, and required shareholder meeting submission. It is not a full financial report (10-K/IR), earnings release (ER), management change (MANG), proxy statement (PSI), or other specific category.
