STOCKS | Jin'an Guoji Denies Nvidia and Huawei Supply Chain Claims After Share Price Volatility

Jin'an Guoji said its shares were flagged for abnormal trading volatility after the stock’s cumulative closing-price deviation reached 20% over two consecutive sessions on June 9, 2026, and June 10, 2026. According to Jin10, the company said online claims that its products had been included in Nvidia’s or Huawei’s supply chain certification systems were false. It said it has not had contact with Nvidia or Huawei and has not carried out any form of business cooperation with either company. Jin'an Guoji said its copper-clad laminate products mainly include general-purpose FR-4 and CEM-3 series laminates, as well as specialty laminates with specifications such as halogen-free and lead-free environmental standards, high flame retardancy, CAF resistance, high Tg, and high CTI, along with aluminum-based laminates and prepregs. The company said its main customers are PCB manufacturers. It added that it has not found applications for its products in AI servers or computing power-related fields. The company said its high-frequency and high-speed copper-clad laminate products remain in laboratory R&D and customer sampling stages and have not generated revenue. It said one high-speed laminate product with a dielectric constant of Dk 3.81 (10GHz) and dielectric loss of Df 0.0047 (10GHz) is being sampled to domestic customers, but whether it can pass customer certification is uncertain. Other related products are in early-stage development and do not yet have samples, and the company said R&D progress and outcomes remain uncertain.
