Dear Secretary, how is the progress of the company's eight-inch silicon carbide? Who are the main customers of automotive-grade carbide? Has the newly built production capacity been put into production? What is the expected shipment volume next year?

Sanan Optoelectronics: Hunan Sanan, a wholly-owned subsidiary of the company, is one of the few vertically integrated manufacturing platforms in the silicon carbide industry chain in China, and 8-inch silicon carbide substrates have achieved small-scale trial production. The company's silicon carbide chips have been widely used in photovoltaics, energy storage, new energy vehicles, charging piles and other fields with high reliability requirements. The company's silicon carbide MOSFET 1200V and 1700V series products include 80mΩ/32mΩ/20mΩ/16mΩ/1mΩ. The products are industry-leading in terms of on-resistance characteristics, breakdown voltage characteristics and threshold voltage stability; 80mΩ products have been introduced in batch orders for photovoltaic and on-board charger clients; automotive-grade 1200V16mΩ has been verified by several strategic customers, and is expected to be officially put into mass production in 2024. The MOSFET foundry business has cooperated with leading new energy vehicles and supporting companies. At present, Hunan Sanan is focusing on promoting product delivery based on the long-term procurement agreement that has been signed, and continues to follow up on the cooperation intentions of several new energy vehicle customers.
