Tongding Internet clarifies: There is no business relationship with NVIDIA.

Tongding Interconnection releases a clarification announcement. The company discovered that a WeChat public account published an article titled "Riding on Nvidia, A-share Fiber Optics Stock to Rise Over 300% Within the Year" on May 12, 2026. Upon verification, Corning serves as a supplier and sells preform fiber rod products externally. The company purchases fiber rods from Corning for fiber production. As of now, Hainan Corning only serves as the company's raw material supplier for fiber rods, with a limited procurement scale. The average annual procurement quantity from 2023 to 2025 was 187.25 tons/year, and there is no exclusive supply situation nor any other cooperation relationship. In the future, the company will reduce external procurement by producing fiber rods internally. The title and content of the aforementioned public account article may mislead investors' judgments, and the statement "Riding on Nvidia" is inaccurate, and the conclusion is not valid. The company has no business relationship with Nvidia.
