Dingxin Communications: The company's core business has not undergone significant changes

Announcement of abnormal fluctuations in the stock trading of Dingxin Communication. The company focuses on the research, development, production, and sales of power line carrier communication and smart grid equipment, with its core business revolving around “smart meter data transmission, power safety protection,” and fire protection services. There have been no significant changes in the company’s core business. The market entry restrictions imposed by State Grid Corporation of China and China Southern Power Grid Limited Liability Company have expired, but the company’s national-level bidding and provincial-level bidding have been stagnant for a period of time and will need time to gradually recover. We urge all investors to pay attention to investment risks.
