Filing Released Lang Actions
兰石重装董事、高级管理人员薪酬管理制度
Governance Information Classification · 99% confidence The document is an internal “董事、高级管理人员薪酬管理制度” (Directors and Senior Management Compensation Management System) detailing policies, principles, and procedures for board and executive remuneration. It sets out governance rules rather than announcing a shareholder vote, financial results, or offering data tables. This aligns with Governance Information, which covers a company’s internal rules and governance practices. Therefore, the correct classification is CGR.

兰石重装2025年度内部控制评价报告2.0
Audit Report / Information Classification · 85% confidence The document is titled “2025年度内部控制评价报告” and contains a comprehensive internal control evaluation including control objectives, defect assessment criteria, and audit committee oversight. It is a standalone internal control assessment report rather than an announcement or part of the full annual report, and does not fit into earnings releases, management discussions, or governance charters. This corresponds to a standalone audit or internal controls report, matching the “Audit Report / Information (AR)” category.

兰州兰石重型装备股份有限公司2025年度内部控制审计报告
Audit Report / Information Classification · 92% confidence The document is clearly an internal control audit report issued by a registered accounting firm (Reanda) for the fiscal year ending December 31, 2025. It includes audit scope, responsibilities, audit opinion on financial reporting internal controls, and auditor signatures. This matches the definition of a standalone Audit Report / Information and does not represent an annual report, interim report, or mere announcement. Therefore, the correct category is AR (Audit Report / Information).

兰石重装关于召开2025年年度暨2026年一季度业绩说明会的公告
Regulatory Filings Classification · 72% confidence The document is an announcement by 兰州兰石重型装备股份有限公司 regarding the scheduling of its 2025 annual and 2026 Q1 performance presentation/earnings explanation meeting. It provides meeting date, venue, participation method, and Q&A procedures. It does not include the actual earnings release, full presentation materials, or financial data itself. It is not a transcript (CT), not the earnings release (ER), not the report itself (10-K/IR), nor a detailed investor slide deck (IP). Therefore it falls under a general regulatory announcement category for miscellaneous filings: Regulatory Filings (RNS).
