Sanda Films' response to executive adjustment: Establishing a joint Stock Representative to ensure a smooth transition of compliance in information disclosure.

On the evening of November 11th, Sinda Membrane announced that its Deputy General Manager and Secretary of the Board of Directors, Zhang Jingxiao, will no longer serve as a senior management member due to a work division adjustment. The company's Chief Financial Officer, Tang Jiajing, will now assume the responsibilities of the Secretary of the Board of Directors. At the same time, Zhang Jingxiao has been appointed as the company's Co-Securities Affairs Representative and will also serve as the General Manager of the Nanofiltration Technology Application and Promotion Center. When asked about the reasons for this job adjustment, Zhang Jingxiao told a reporter from the Shanghai Securities News, "According to the company's work arrangements, my main focus will be on the Nanofiltration Center, with the CFO acting as the Secretary of the Board of Directors. As the CFO acting as the Secretary of the Board of Directors has not yet obtained the qualification certificate, in order to ensure the legality and compliance of corporate governance and information disclosure, and the normal continuation of board work, I have been appointed as Co-Securities Affairs Representative to assist the new Secretary of the Board of Directors and lead the way."
