The company is concerned that the recent rise in international crude oil prices has led to an increase in asphalt prices, and the market has paid more attention to the company's asphalt business. The company's main business is the research and development, production and sales of pavement asphalt series products. Petroleum asphalt is the main raw material of the company's main business. The purchase price of petroleum asphalt is highly related to international crude oil prices, domestic refining capacity and market supply and demand. Rising petroleum asphalt prices will increase the company's raw material procurement costs accordingly; The price adjustment of the company's products is affected by factors such as the price adjustment mechanism of downstream customers and downstream road construction needs. There may be a certain lag in the transmission of costs to terminal prices. In the most recent fiscal year, the company's asphalt business gross profit margin was 4.54%, which is at a low level. If the price adjustment mechanism of the company's products cannot match the increase in raw materials, it will increase the difficulty of the company's cost control and the company's operating risks.
