Filing Released Lang Actions
天通股份关于续聘会计师事务所的公告
Regulatory Filings Classification · 95% confidence The document is an announcement regarding the company's decision to renew the appointment of an accounting firm (auditor) for the upcoming fiscal year 2026. It details the auditor's qualifications, independence, past performance, and the approval process by the audit committee and board of directors. There are no actual financial statements or audit reports included, nor is there a detailed audit opinion or financial data. The document is relatively short (2896 characters) and serves as a formal announcement of the auditor appointment rather than the audit report itself. Therefore, it fits best under the category of a Regulatory Filing (RNS) as it is a regulatory announcement about auditor appointment and related governance matters, not the audit report or annual report itself.
