Regulatory Filings Classification · 85% confidence The document is a formal announcement by Shanghai Kaixin in response to an inquiry letter (年报问询函) from the Shenzhen Stock Exchange regarding the company’s 2025 annual report. It is not the annual report itself but a regulatory compliance communication addressing questions about revenues, margins, cash flow and accounting policies. This type of exchange inquiry reply falls under general regulatory filings rather than a substantive financial report, earnings release or publication announcement.

Regulatory Filings Classification · 78% confidence The document is an official announcement regarding the company’s stock trading status on the Shenzhen Stock Exchange—specifically the revocation of the “*ST” delisting risk warning and the associated trading suspension/resumption arrangements. It is not itself a financial report, nor a dividend notice, nor a management change, but a regulatory compliance announcement. There is no specific category for trading halt/resumption or risk-warning removal other than the general “Regulatory Filings” category. Therefore, it falls under RNS (Regulatory Filings).

It is not a mere announcement or certification but contains substantive financial and management information about the raised funds. Therefore, it fits the category of an Audit Report / Information (AR).
