Recently, Tony Electronics and Luxshow Technology have been unable to deliver silicon carbide substrates to customers as scheduled, and most of the substrates do not meet customer quality requirements. I would like to ask Secretary Dong whether the quality of your company's silicon carbide substrates meets customer requirements and whether they are being delivered to customers on schedule?

Tianyue Advanced: Dear investors, hello! The company focuses on silicon carbide semiconductor materials and is an internationally leading manufacturer of silicon carbide semiconductor materials, committed to providing high-quality products to a wide range of domestic and foreign customers. With independent innovation, the company has fully mastered the core key technologies and has achieved the preparation of 2-inch substrates to 8-inch substrates through independent expansion. The company's customer base includes some international first-tier manufacturers, which have strict requirements and certification processes for products and supply capabilities. At present, the company supplies stable supplies to internationally renowned companies such as Infineon and Bosch. In 2023, the company's production capacity and output will be improved. According to the company's 2023 performance report, the company achieved operating income of 125,069.57 million yuan, a year-on-year increase of 199.90%. At present, the company's production and operation are normal and the capacity construction is steadily advancing, which will help the company to ensure the delivery of new customers and orders. Thank you for your attention!
