Jinlight is a leading company in the field of rechargeable backup devices. The company is mainly engaged in the development, manufacture and sale of rechargeable backup lighting products and rechargeable AC/DC fans. The main products include two categories of rechargeable backup lighting and rechargeable AC/DC fans. The company's main products, other self-supplied portable electric lamps and table fans with an output power of no more than 125 watts, ranked second and third respectively, occupying a leading position in the industry. The stable market growth rate and low concentration provide broad space for the company. The contradiction between electricity supply and demand in developing countries, the rise of outdoor lifestyles in developed countries, and natural disasters arousing people's safety awareness have supported the industry to maintain a growth rate of 10%-20%. Furthermore, the current export share of the top ten domestic manufacturers, which account for less than 20%, has created huge space for the company's development. R & D technology and marketing networks are the company's core competitiveness. Since its establishment, the company has always attached importance to technology research and development, and all products are completed through independent research and development. Currently, the company has a rechargeable core technology. In the future, it will continue to develop different products around this core technology, laying the foundation for future company growth. The company's products are mainly exported. At present, it has established a marketing network covering more than 70 countries and regions around the world, and adopted a combination of three methods: exclusive sales, cooperative sales, and open sales to grow together with customers. We expect the company's net profit for 13-15 to be 0.41,0.59,071 million yuan, with a 3-year compound growth rate of 31.9%. Since there is a problem with the number of shares issued in stock in this offering, the total share capital after issuance is related to the issue price. Considering the company's leading position in the field of rechargeable backup equipment and taking into account the valuation situation of comparable companies, we expect that the valuation level of the company after listing may be 18-22 times in 2014, the corresponding calculated stock price range is 11.28-14.65 yuan, and the corresponding EPS issued at a price-earnings ratio of 0.45, 0.64, and 0.78 yuan is 0.45, 0.64, and 0.78 yuan.
