Filing Released Lang Actions
天津七一二通信广播股份有限公司对外捐赠管理制度
Governance Information Classification · 1% confidence The document is an internal management system (“对外捐赠管理制度”) outlining the company’s rules, procedures, and governance for external donations. It is not a financial report, announcement of results, or regulatory filing but rather a corporate governance document detailing internal policies. This matches “Governance Information” (Code: CGR).
2026-04-22 Chinese
天津七一二通信广播股份有限公司2025年度审计报告及财务报表
Audit Report / Information Classification · 1% confidence The document is titled “审计报告及财务报表” for the full year ended December 31, 2025, issued by BDO. It contains the auditor’s opinion, scope, key audit matters, and the complete set of audited financial statements and notes. This corresponds to a standalone audit report and financial statements rather than a full annual report (10-K) or a brief announcement. Therefore, it fits the Audit Report / Information category.

天津七一二通信广播股份有限公司2025年度独立董事述职报告（沈涛）
Governance Information Classification · 1% confidence The document is an annual duty performance report by an independent director, detailing governance activities, board and committee attendance, and compliance with governance rules. It is not announcing a board change, nor a financial report, nor an earnings release. It is a governance-related disclosure describing board structure and the director’s responsibilities. Therefore it best fits “Governance Information” (CGR).

天津七一二通信广播股份有限公司董事会审计与风险控制委员会对会计师事务所2025年度履行监督职责情况的报告
Regulatory Filings Classification · 1% confidence The document is a formal report by the Board’s Audit and Risk Control Committee on its supervision of the external auditor’s performance for the 2025 year. It is not the company’s full annual report (10-K) nor the audit opinion itself, but rather a compliance‐oriented oversight report required by regulations. It does not fit other specialized categories (e.g., dividend notice, management change, earnings release), so the most appropriate classification is a general regulatory filing (RNS).
2026-04-22 Chinese
天津七一二通信广播股份有限公司关于独立董事独立性情况评估的专项意见
Governance Information Classification · 1% confidence The document is a board-issued special opinion assessing the independence of the company’s independent directors under relevant CSRC and exchange rules. It pertains to governance practices and internal board oversight rather than announcing financial results, a change in board composition, dividends, or an AGM outcome. This clearly falls under Governance Information (CGR).
