The company is mainly engaged in R&D, production and sales of polymer composite shading materials (sunshine fabrics) products. It is mainly used in three categories of energy-saving shading for buildings, construction engineering materials, and other industrial fabrics, which have the advantages of energy saving, environmental protection, durability, and flame retardancy. Tests have shown that the sunshine fabric can block more than 65% of thermal radiation and more than 95% of ultraviolet rays, and the company's products have reached or even surpassed the level of similar products in the same international industry in terms of technology. Currently, China's construction energy consumption accounts for about 28% of the energy consumption of the whole society. Construction consumes 1.2 trillion kilowatts of electricity every year, and the domestic building energy efficiency market is over trillion yuan. In terms of electricity consumption in buildings, windows are a key factor, so the prospects for future building shading products for windows are promising. Polymer composite shading materials are in a period of growth in developed countries. Demand is stable and continues to grow, and the market capacity is huge. The scope of application includes hotels, office buildings, public facilities and ordinary homes. At home, on the other hand, it is an emerging development industry. It is in the market introduction period. It is a new energy-saving and consumption-reducing material encouraged by the national industrial policy, and has broad prospects for development. Before 2000, it mainly relied on imports. Domestic manufacturers began to appear in 2003, and products began to be exported in 2006. Currently, applications are mainly in large hotels, stadiums, and public works facilities. In the future, driven by the concept of environmental protection and consumption upgrades, the housing construction market will receive more and more attention. The company has technical advantages, product advantages, customer service and distribution advantages, and has maintained a relatively rapid growth rate since its establishment, with a compound revenue growth rate of 49.21% in 07-09. Currently, the domestic and foreign sales ratio is approximately 30%: 70%. Currently, the company and well-known foreign manufacturers in China occupy the vast majority of the middle and high-end market share of the main materials (fabrics) of second-generation sunshade products. The company's capital raising projects are mainly for the construction of a 6 million square meter polymer composite project to expand production of new materials. Currently, the production capacity is about 6.5 million square meters, which has nearly doubled the production capacity after delivery. We expect the company's diluted earnings per share in 2010, 2011, and 2012 to be 0.35 yuan, 0.53 yuan, and 0.85 yuan respectively. Based on comparable company valuations, we think a reasonable valuation is 23.85 yuan to 26.50 yuan, corresponding to a price-earnings ratio of 11 EPS of 45-50 times, and PEG of 0.80 to 0.90.
