# Ultrasonic Electronics Says No Nvidia Supply After 3-Day Share Surge Triggered Trading Alert

Ultrasonic Electronics said its shares were flagged for abnormal trading after the cumulative deviation in closing-price gains exceeded 20% over three consecutive sessions on June 24-26, 2026, according to 36Kr. In a June 28, 2026 announcement, the company said operations are normal and it has seen no major changes in its business or operating environment. The company said its copper-clad laminate unit is not producing M8 or M9 copper-clad laminates, and its M7/M8-grade high-speed copper-clad laminates are still in R&D testing. It added that PCBs supporting 800G and 1.6T optical modules are under research follow-up, with uncertainty around progress, customer certification and mass production; the products have not been supplied at scale and have generated no revenue so far. Ultrasonic Electronics also said market rumors that its high-frequency boards have passed Nvidia certification are untrue, and it currently has no products supplied to Nvidia.
