Are many of the company's key raw material suppliers overseas? Will future changes in the international situation affect the company's overseas raw material imports and raw material quality?

Weimaisi: Dear investors, hello! The company's chips, power devices and other semiconductor materials are mainly purchased from advanced overseas manufacturers, forming a supply pattern dominated by international advanced brands and supplemented by domestic brands. Advanced overseas manufacturers include STMicroelectronics, ON Semiconductor, Infineon, Texas Instruments, NXP, Microchip, etc. In recent years, with the emergence of many semiconductor material manufacturers in China, actively carrying out R&D and production investment, the company continues to explore more possibilities for the application of raw materials from domestic suppliers in the company's products. Thank you for your attention to the company.
