Cambridge Technology: Currently do not produce chips containing CPO technology.

Announcement of abnormal fluctuations in Cambridge Technology's stock trading: Regarding the market's attention to CPO and LPO related businesses, the company would like to make the following special clarifications: The company currently does not manufacture chips with CPO technology. The core components of CPO, the light engine, and the external light source ELSFP are in the cooperative research and design stages and have not yet generated any business income. Although LPO business samples have been sent for testing to multiple large North American customers, the cumulative order and shipment amount in the first half of 2025 only account for approximately 0.03% of the same period's revenue, making a very minimal contribution to the company's current performance. Investors are advised to rationally assess the company's progress in the emerging technology field and not overly interpret the impact of related businesses on short-term performance, while also paying attention to the uncertainty and risks involved in business implementation.
