To all shareholders of Beijing Shuangjie Electric Co., Ltd.:
In accordance with the "Basic Norms for Enterprise Internal Control" and its supporting guidelines, as well as other internal control regulatory requirements (collectively referred to as the "Internal Control Norms System"), and combined with Beijing Shuangjie Electric Co., Ltd.'s (hereinafter referred to as the "Company" or "this Company") internal control system and evaluation methods, based on daily supervision and special supervision of internal controls, we have evaluated the effectiveness of the Company's internal controls as of December 31, 2025 (the benchmark date for the internal control evaluation report).
I. Important Statement
In accordance with the requirements of the Internal Control Norms System, establishing and improving a sound and effective internal control system, evaluating its effectiveness, and truthfully disclosing the internal control evaluation report are the responsibilities of the Company's Board of Directors. The Audit Committee supervises the establishment and implementation of internal controls by the Board of Directors. The management is responsible for organizing and leading the daily operations of the Company's internal controls.
The Company's Board of Directors, Audit Committee, directors, and senior management guarantee that the content of this report contains no false records, misleading statements, or significant omissions, and they bear individual and joint legal responsibility for the truthfulness, accuracy, and completeness of the report's content.
The objective of the Company's internal control is to reasonably ensure that business management is legal and compliant, assets are safe, financial reports and related information are true and complete, operational efficiency and effectiveness are improved, and development strategies are promoted. Due to the inherent limitations of internal control, it can only provide reasonable assurance for achieving these objectives. Furthermore, changes in circumstances may render internal controls inappropriate, or reduce the degree of compliance with control policies and procedures, and there is a certain risk in inferring the future effectiveness of internal controls based on the results of the internal control evaluation.

Based on the determination of material weaknesses in non-financial reporting internal controls, as of the benchmark date of the internal control evaluation report, the Company has not found any material weaknesses in non-financial reporting internal controls.
