LED listed companies invariably attributed the sharp decline in profits to the fact that the market environment in 2012 was too bad and competition increased.
According to statistics, in the LED listed companies that have released the 2012 annual report and performance report, the net profit of Silan Micro declined the most, down more than 80% year-on-year; the net profit of Maoshuo Power, which had the smallest decline in performance, also fell 9.76% year-on-year. Last year, the net profit of the entire industry fell by about 30%.
LED chips and epitaxial wafer companies in the upstream of the industrial chain, such as Huacan Optoelectronics, Silan Micro, Ganzhao Optoelectronics, and Dehao Runda's 2012 net profit fell 30.38%, 88.07%, 39.33%, and 57.14%, respectively; The net profit of the company's shareholders was 87 million yuan, 18 million yuan, 100 million yuan and 168 million yuan respectively. LED luminescent materials company Keheng shares net profit fell 80.62%; LED crystal material provider Fujing technology net profit fell 34.12%; LED power supply company's Moso power net profit fell 9.76%; LED packaging company rectangular lighting, Lehman Optoelectronics, The net profit of Hongli Optoelectronics and Guoxing Optoelectronics decreased by 27.45%, 27.36%, 34.49% and 66.45% respectively.
In order to support the LED industry, the state proposes to promote the annual growth rate of LED lighting energy-saving industry output value by about 30%, and reach the target of 450 billion yuan in 2015. With the aura of emerging industries and governments at all levels, LED companies have always been favored by capital. However, the domestic investment boom in the LED industry has caused LED industry, such as wind power and photovoltaic industry, to have a serious overcapacity, leading to 2011. The price of LED's entire upstream and downstream industry chain has fallen sharply at the same time. In the current global LED market downturn, upstream chip companies are faced with problems such as repeated fluctuations in raw material prices, high operating costs, and patent barriers in overseas markets.
