As of April 27, 2018, 31 of the listed companies in the mainland A-share LED segment have published their first quarterly results for 2018. According to the results of the 31 listed companies listed by OFweek Semiconductor Lighting Network, 2018, with With the continuous improvement of LED boom, the profitability of listed companies in the LED industry has ushered in a comprehensive recovery. As of April 27, 2018, 31 of the listed companies in the mainland A-share LED segment have released their first quarterly results for 2018. According to the performance forecasts of 31 listed companies by OFweek Semiconductor Lighting Network, 23 The net profit of home companies increased, and the net profit of 8 companies declined. Comparison of Continental LED Enterprise Revenue and Net Profit in the First Quarter of 2018 As can be seen from the above chart, the net profit growth of the three listed companies of Alto Electronics, Dehao Runda and Guangdong Ganhua exceeded 100%. Sanan Optoelectronics, Aoyang Shunchang, Ganzhao Optoelectronics, Mulinsen, Hongli Zhihui, Guoxing Optoelectronics, Ruifeng Optoelectronics, Changfang Group, Guangqi Shares, Op Lighting, Snowlight, Mingjiahui, Sanxiong Aurora, Ocean King The net profit growth of 20 listed companies in Lighting, Huati Technology, Tailong Lighting, Chau Ming Technology, Liard, Ai Bison and Infineon ranged from 0% to 100%. The net profit of Maoshuo Power Supply, Overclocking III, Yuanfang Information, Lehman Shares, Weiwei Shares, Debang Lighting, Jufei Optoelectronics and Jucan Optoelectronics listed companies decreased compared with the same period of last year. Among them, Guangdong Ganhua and Dehao Runda's net profit fell sharply. From the 2017 annual report of the major LED industry and the 1st quarter of 2018, the core financial indicators of listed companies all showed obvious improvement trends. The core indicators include ROE, revenue scale and growth rate, net profit and growth rate of returning home, gross profit margin. , net profit and operating cash flow. The core financial data of the LED industry has improved significantly, and the LED industry trend has been verified to be solid and reliable. As the concentration of the LED market continues to increase, many leading companies in the LED industry chain have expanded their production capacity, hoping to seize market share. It can be seen that the future LED industry will present the situation of the big one. In recent years, the demand for downstream applications has grown strongly, and the penetration rate of LED lighting has risen rapidly. Moreover, with the rapid growth of the market for small-pitch LEDs, the opening of LEDs for MicroLED/Mini LEDs, and the expansion of LED applications, it is expected that downstream applications will continue to grow steadily for a long time to come. On the other hand, global LED manufacturing is showing a general trend of shifting to China. Based on this, some industry analysts believe that China's electronics industry has fully possessed excellent process control and cost management capabilities over the years, and the engineers' dividends are gradually being released, prompting Chinese companies to develop and own more independent intellectual property rights. International advanced technology. With the slowdown in the technological advances of international manufacturers, Chinese companies will have the opportunity to make full use of national policies, industrial capital and engineer dividends to achieve post-production, with the goal of defeating traditional international giants. The following are the performance reports of LED listed companies.
