In the first half of 2012, the most important key word for the external environment of the LED industry was policy, and the protagonist was the government. From the country to the local, the policy of the LED industry has been continuously promoted. However, specific to the industry, the keyword is a decline, 70% of the LED industry listed companies' revenue and net profit have experienced varying degrees of decline.
The contrast between positive and negative seems to be embarrassing, but it is also logical. Although the policy is hot, the decline in export orders is a major trend that has been staged since last year. The stimulating effect of national policies is also difficult to release in the short term, which has caused the overall industry to be tepid. On the other hand, the industry has gradually entered the public. Vision, but high prices still hinder the further popularization of LEDs.
It can be said that the entire first half of the year is the adjustment period of the LED industry. Throughout 2012, it will also become an adjustment period for the LED industry. At the same time, although the mad growth of the LED industry in the early years of development will no longer exist, but under the long-term favorable policies of the country, the LED industry will still have rapid growth in the growth period.
Half-year negative growth in the first half of the year
As of mid-August, 20 LED listed companies have announced the first half of 2012 performance report or performance warning report. Among them, more than half of the company's operating income showed a negative growth trend, while 15 companies experienced a decline in operating profit. In addition, the net profit of 70% of enterprises has a significant downward trend.
Among them, Weiwei shares are expected to decline by as much as 94.12%-95.85%, which the company blamed for the downturn in the external environment. Wei Wei said that due to the impact of the decline in orders in the US market and the domestic market is still in the stage of cultivation and development, the company's overall sales revenue decreased year-on-year; in order to open up the domestic market as soon as possible and develop products suitable for the domestic market demand, the company has continued since the second half of last year. Expanded the R&D team and built a sales team in the domestic market. During the reporting period, R&D expenditure and domestic sales expenses were increased.
Huacan Optoelectronics, which is also in the LED industry, has announced its semi-annual report. In the first half of the year, the company achieved operating income of 187,177,500 yuan, down 17.79% over the same period of the previous year; total profit was 4,363,580 yuan, down 39.25% over the same period of last year; net profit was 3,709,400 yuan, down 39.4% over the same period of the previous year. Due to the intensified market competition, the sales unit price of Huacan Optoelectronics Chip decreased more than expected, while the capacity expanded by the company was not fully formed and released during the same period. As a result, the number of chip sales in the first half of the year exceeded the number of production warehousing, which was also higher than the same period last year, but sales. Revenue and gross profit still fell, and net profit was significantly lower than the same period last year.
Of course, there are also companies in the performance report that maintain revenue growth, such as Sanan Optoelectronics. According to Sanan Optoelectronics' semi-annual report, in the first half of 2012, its operating income was 1,378,046,000 yuan, an increase of 90.53%, but the relative increase in net profit was only 1.55%. The doubled growth in operating income and the almost in-situ step in net profit show a sharp decline in the overall gross profit of Sanan Optoelectronics.
The overall performance is slightly better. It is expected that the net profit attributable to shareholders of listed companies will increase from 10.00% to 40.00% in the same period of the previous year. However, the reporter found that the main reason for the company’s net profit growth is still It is a government subsidy received in the first quarter. At the same time, the company's performance forecast net profit growth rate has started to slow down compared to last year.
On the whole, although some companies' operating income has increased, the net profit growth has been slow, and most of the company's net profit has not increased and decreased, indicating that production efficiency is still not optimistic.
The industry still faces internal and external problems
All listed companies have said that the export demand of the LED industry has fallen sharply due to the negative impact of the global economic downturn. The downturn in the European and American markets has been particularly hard on the industry.
At present, European and American countries are the main markets for domestic LED exports. Taking Guangdong Province as an example, in 2011, the export sales of LED lamps in Guangdong was more than 34 billion yuan, accounting for 1/4 of the total output value of LED lamps in Guangdong. Among them, the export value to the United States and the European Union is about 22 billion yuan, accounting for about 2/3 of the export value of LED lamps in Guangdong, accounting for 15% of the total output value of LED lamps in Guangdong.
In addition to the economic downturn, the resistance posture of European and American countries to China's LED products is also becoming more and more obvious. In the first half of the year, major exporting countries such as Europe and the United States also raised the threshold of LED products and erected high walls of technical trade barriers to protect domestic enterprises.
The WTO/TBT Center of the Guangdong Provincial Quality Supervision Bureau recently reported that the United States, the European Union and other countries and regions have proposed higher and stricter coverage of imported directional lamps and LED lighting products covering energy conservation, environmental protection, ecological design, energy efficiency labeling, testing and inspection. Claim. For the directional lamps and LED lighting products entering the country, higher and stricter requirements covering energy conservation, environmental protection, eco-design, energy efficiency labeling, test and inspection, performance, safety, size, weight and shape are proposed.
A European Union regulation puts forward energy efficiency requirements for directional lights and LED lights. The notification regulations require that only directional LED lamps and directional fluorescent lamps with an energy efficiency index of more than 0.2 can enter the EU market, which is 2.5 times higher than the previous energy efficiency requirements, which is 2.2 times the current national standard requirements. It is estimated that according to the above energy efficiency requirements, the production cost of LED lamps will directly increase by more than 20%, which will bring additional costs of more than 2 billion yuan to LED enterprises in Guangdong.
