2022-022关于改聘会计师事务所的公告
Regulatory Filings Classification · 95% confidence The document is an announcement regarding the change of the company's auditor (accounting firm). It details the new auditor's qualifications, the reasons for the change, the communication with the previous auditor, and the approval process by the board and audit committee. It does not contain any financial statements or audit reports themselves, but rather the announcement of the appointment of a new audit firm. The document length is 3089 characters, which is relatively short and consistent with an announcement rather than a full audit report. Therefore, this document is best classified as a Regulatory Filing (RNS) because it is a regulatory announcement about auditor change and does not contain the audit report itself.

天璇2022年4月30日审计报告
Audit Report / Information Classification · 95% confidence The document is titled as an "审计报告" (Audit Report) for 河南天璇半导体科技有限责任公司, issued by a registered accounting firm. It contains detailed audit opinions, financial statements (balance sheet, income statement, cash flow statement, statement of changes in equity), and extensive notes on accounting policies and estimates. The period covered is the first four months of 2022, with specific dates such as April 30, 2022, mentioned. The content is comprehensive and includes auditor responsibilities, management responsibilities, and detailed financial data. This matches the definition of an Audit Report / Information (AR), which includes standalone audit reports and applied accounting principles, excluding full annual reports. The document is not an Annual Report (10-K) because it covers only a partial period (1-4 months) and is focused on the audit opinion and financial statements rather than a full yearly report. It is not a Regulatory Filing (RNS) or Report Publication Announcement (RPA) because it contains the full audit report and financial data, not just an announcement or certification. Therefore, the correct classification is AR with high confidence. Q1 2022
