The research report released on January 28 said that the recommended rating of Leyard Optoelectronic Co.Ltd(300296) (300296. SZ) was maintained. The reasons for the rating mainly include: 1) the company's revenue in 2021 is in line with the expectation, and the profit in the fourth quarter decreased slightly month on month due to the impact of goodwill impairment and expense recognition; 2) Display and VR business increased significantly; 3) The company is expected to lead the next round of growth in the industry. Risk warning: the downstream demand is less than expected, and the R & D and application of new technology is less than expected.
