Ruichuang Micronano: Hello! 1. The complete machine products sold overseas by the company have both dealer brands and self-owned brands. The self-owned brand is "Infiray". The dealer brand is inconvenient to disclose due to commercial confidentiality. 2. The company has not separately disclosed the sales situation in various countries. Overall, the company's products have been sold to dozens of countries in Europe, America, Asia, Australia, Africa and other regions, covering a wide market. Because there is no authoritative organization to conduct statistics on market conditions, we cannot give the market penetration rate in various countries. 3. The 8-inch MEMS wafer production line jointly built by the company and the wafer foundry has a production capacity of 1,500 wafers per month and can produce 3.6 million chips of various types annually. At present, the production capacity is sufficient and the supply chain is normal. There is no situation that production and delivery are affected by chip shortages. 4. The company's long-term development strategy is to adhere to the science and technology leadership, technology leadership, promote vertical integration business model, focus on the infrared field to do better, expand horizontally into other fields to become stronger, improve the company's economic benefits, create value for society, and strive to build China's most valuable special chip company. Entering the refrigeration infrared field is an important step in the company's development strategy. In the field of refrigeration infrared, the company successfully developed a 15μm 640×512 long-wave type II superlattice chip in 2020, which is now in the design verification test stage; the domestically produced refrigeration core FX640G has entered the design verification test stage; the miniaturized refrigeration core FX640S has entered the engineering verification test stage. Up to now, the company's refrigeration products are all in the development stage, with a small number of prototype orders, but the contribution to revenue is not large. Please invest cautiously and pay attention to risks. Thank you for your attention!
