Tongding Interconnection: Stock trading abnormal volatility has no business relationship with Nvidia.

Tongding Interconnect announced that the company's stock has experienced abnormal fluctuations with a cumulative deviation of over 20% in the closing prices for three consecutive trading days from June 15 to 17, 2026. After verification, the company's previous disclosures do not require correction or supplementation. An article on a certain public account contains misleading information, as the company has no business relationship with NVIDIA and Corning is only a supplier of optical rod materials. The company's operations are normal, and both internal and external environments remain unchanged. The company advises investors to be cautious and rational in their investments and reminds them of multiple risks.
