Investor's question: The company can predict that the sales revenue of black phosphorus this year will not exceed 500000 yuan, and it feels that the company is interested in Cui Xiuguo

Investors' questions:

The company can predict that the sales revenue of black phosphorus will not exceed 500000 yuan this year. How does the company feel that it has no confidence in Professor Cui Xiuguo's black phosphorus team? Please estimate the sales revenue of black phosphorus in 2025? The company mentioned earlier that the sales data expected to be realized this year is small and cannot be accurately predicted, and later mentioned that the sales revenue of synthetic biology is expected to not exceed 1 million yuan. It seems that the company has no hope for Ruifeng Biology. The company needs to improve the pattern, and companies with pattern prefer to use "far ahead". Dreams come true. It is hoped that the company leaders can do practical things, make more profits, bring better returns to investors, and make the company stronger and larger.

Hello! The company actively promoted the development of relevant businesses as planned, but the new products and businesses mentioned above are still in the initial stage or the experimental stage, and cannot be achieved overnight. The above prediction is also based on the stage of the project and the preliminary prediction based on the attitude of being responsible to the investors, which has nothing to do with the pattern. If we use absolute terms to disclose projects and mislead investors, there is no pattern. Please refer to the information publicly disclosed by the company on the designated information disclosure media www.cninfo. com. cn, and pay attention to the investment risk. Thank you for your attention!
