Filing Released Lang Actions
鼎信通讯2025年度董事会工作报告
Governance Information Classification · 1% confidence The document is titled “2025年度董事会工作报告” (2025 Board of Directors Work Report). It is not an announcement of financial results (ER) or a full annual report (10-K); rather, it describes the board’s composition, meetings, governance structure, internal rules revisions, and compliance measures. It is not simply announcing a report publication (RPA) nor is it a management discussion & analysis (MDA) in the strict sense. The content aligns with “Governance Information” (CGR): a detailed report on board structure, governance practices, and compliance. Thus, the correct classification is CGR.

Governance Information Classification · 1% confidence The document is titled “2025年度独立董事述职报告” and contains a detailed self‐evaluation by the independent director of board attendance, committee work, internal controls, audit communications, governance activities, and professional training over the year. It is not a financial statement, earnings release, or announcement of a specific transaction; rather, it is a corporate governance disclosure about board structure and independent director performance. This corresponds to Governance Information (CGR).

独立董事候选人声明与承诺（周咏梅）
Proxy Solicitation & Information Statement Classification · 1% confidence The document is a formal statement and commitment from an independent director candidate for Qingdao Dingxin Communications Co., Ltd., outlining qualifications, independence criteria, and declarations. It is part of materials provided to shareholders in connection with board elections, typical of proxy solicitation documents rather than an actual announcement of appointment or change. Therefore, it best fits the Proxy Solicitation & Information Statement category.

鼎信通讯关于续聘会计师事务所的公告
Regulatory Filings Classification · 1% confidence The document is an announcement by the company’s board regarding the reappointment of an external auditing firm for the upcoming fiscal year’s audit services. It does not contain the audit report itself (AR) nor is it a financial report publication (RPA) or proxy/meeting materials. There is no specific category for auditor appointment, so it defaults to a general regulatory announcement. Therefore, the correct classification is Regulatory Filings (RNS).
