Audit Report / Information Classification · 95% confidence The document is a detailed verification opinion from Huatai United Securities Co., Ltd. regarding the 2022 internal control self-assessment report of Shenzhen Defang Nano Technology Co., Ltd.

The document is a standalone audit-related report focusing on internal control evaluation and verification, issued by a sponsoring institution, and does not contain full annual financial statements or comprehensive company activity reports. It is not an Annual Report (10-K) but rather an Audit Report / Information (AR) related to internal control verification and audit opinion. The document length and content confirm it is a full report, not just an announcement or certification letter, so it should be classified as AR. FY 2022
