The company has elaborated the risk factors of the company’s core competitiveness risk, operation risk and industry risk in this report. Please refer to the “risk factors” in Section III “management discussion and analysis” of this report. Investors are reminded to pay special attention to the following risks:

1. Risk of sharp decline in performance or loss in 2022

In 2021, recombinant human tumor necrosis factor receptor antibody fusion protein was included in the centralized procurement list of 153 drug groups including diclofenac of Guangdong alliance. In March 2022, the company’s core product ISAP won the bid with the price of 127 yuan / piece as the proposed alternative product, with a price decrease of 60%, which will have a certain impact on the growth of the company’s operating revenue. At the same time, in order to cope with the increasingly fierce market competition environment, the company does not rule out the possibility of further reduction of product prices in the future.

In view of the continuous deepening of the company’s R & D project process and the forward-looking layout of the future antibody drug R & D field, the early investment of R & D projects increases, and the R & D investment of research projects increases with the needs of their R & D stage. It is expected that the company will continue to generate a large amount of R & D expenses in the future. If the R & D expenses are greater than the profits generated by commercial products, the company will suffer losses.

2. The R & D of innovative drugs faces uncertainty and greater market competition risks

The R & D of innovative drugs has the characteristics of long R & D cycle, large investment, high risk and low success rate. From the project establishment to the approval and listing of new drugs, there are many complex links, such as preclinical research, clinical trials, registration and listing of new drugs and after-sales supervision. Each link may face the risk of failure. In addition, considering the risk of drug research and development and the uncertainty of market competition faced by the future product listing, if the company cannot effectively make use of its R & D technology experience, large-scale production advantages or terminal sales coverage, the products under research may not be approved for listing first among the products with the same target, and the related products will face a more competitive market environment, Then it will have an adverse impact on the growth of the company’s operating performance and sustainable profitability.

In the future, the company needs to continue the research and development of innovative drugs to ensure that the company continues to introduce new products to the clinic and then to the market. However, the company cannot guarantee that it can continuously find indications with commercial value. The potential products screened by the company may not have further development potential due to insufficient effectiveness and other reasons. If the company cannot continuously develop new products with commercial potential, it may have an adverse impact on the company’s business. 3 the board of directors, the board of supervisors and the directors, supervisors and senior managers of the company guarantee that the contents of the annual report are true, accurate and complete, and there are no false records, misleading statements or major omissions, and bear individual and joint legal liabilities. 4.
