Interim / Quarterly Report Classification · 100% confidence The document is titled "天通控股股份有限公司2025 年第一季度报告" which translates to "Tiantong Holdings Co., Ltd. 2025 First Quarter Report."

The report explicitly states it is a quarterly report and includes unaudited financial statements for the period ending March 31, 2025.

Audit Report / Information Classification · 95% confidence The document is a correction announcement regarding a previously issued special audit report on non-operating fund occupation and related party fund transactions. It references a specific audit report issued by an accounting firm and details corrections to financial data tables. The document is not the audit report itself but a correction notice about it. It is a standalone announcement related to audit information, specifically a correction to an audit report. Therefore, it fits best under the category Audit Report / Information (AR). The document length is sufficient and contains detailed financial data corrections, supporting this classification. FY 2024

Audit Report / Information Classification · 95% confidence The document is an announcement regarding the reappointment of an accounting firm (auditor) for the company for the upcoming fiscal year 2025. It details the auditor's qualifications, independence, past litigation, and audit fees, and mentions that the reappointment will be submitted to the shareholders' meeting for approval. The document does not contain any financial statements or audit reports themselves, but rather is a formal announcement about the auditor appointment process. The document length is 2776 characters, which is relatively short and consistent with an announcement rather than a full audit report. Therefore, this fits best under the category of Audit Report / Information (AR), which includes standalone audit reports and related information such as auditor appointments and audit firm details, excluding full annual reports.
