The company reminds investors to pay attention to the investment risks in the initial stage of IPO (hereinafter referred to as “new shares”), and investors should fully understand the risks and rationally participate in the trading of new shares.

Specifically, the risks at the initial stage of IPO of the company include but are not limited to the following:

(I) relaxation of price limit

The competitive trading of GEM stocks is subject to a wide range of price limits. For stocks that are IPO and listed on the gem, there is no price limit in the first five trading days after listing, and then the price limit is 20%. On the first day of the listing of new shares on the main board of Shenzhen Stock Exchange, the increase limit was 44%, the decrease limit ratio was 36%, and the increase and decrease limit was 10% from the next trading day. The gem further relaxed the limit on the rise and fall range at the initial stage of stock listing, improving the trading risk.

(II) a small number of tradable shares

After this issuance, the total share capital of the company is 108.01 million shares, of which the number of tradable shares without sale conditions is 23516089 million shares, accounting for 21.77% of the total share capital after issuance. At the initial stage of listing, the number of circulating shares is small, and there is a risk of insufficient liquidity.

(III) the shares can be used as the subject matter of margin trading on the first day of listing

The stock can be used as the subject matter of margin trading on the first day of listing, which may produce certain price fluctuation risk, market risk, margin increase risk and liquidity risk. Price fluctuation risk refers to that margin trading will aggravate the price fluctuation of the underlying stock; Market risk refers to that when investors use stocks as collateral for financing, they need to bear not only the risks caused by the change of the original stock price, but also the risks caused by the change of the stock price of new investment, and pay the corresponding interest; Margin call risk means that investors need to monitor the level of guarantee ratio in the whole process of trading to ensure that it is not lower than the maintenance margin ratio required by margin trading; Liquidity risk refers to that when the price of the underlying stock fluctuates violently, the financed purchase of securities or the repayment of securities, the sale of securities or the repayment of securities may be blocked, resulting in greater liquidity risk. (IV) there may be a risk of falling below the issue price after listing

Investors should pay full attention to the risk factors contained in the pricing marketization, know that the stock may fall below the issue price after listing, effectively improve the risk awareness, strengthen the value investment concept, and avoid blind speculation. Regulators, issuers and recommendation institutions (lead underwriters) can not guarantee that the stock will not fall below the issue price after listing. 3、 Special risk tips

The company reminds investors to carefully read the chapter “section IV Risk Factors” of the company’s prospectus, and especially reminds investors to pay attention to the following risks in the “risk factors”: (I) the risk that the performance cannot grow continuously and rapidly or even decline

The development of the company’s business is affected by internal and external factors. In the future, there are risks that the company’s business scale cannot grow continuously and rapidly due to the slowdown of downstream demand, the failure of technology promotion to meet expectations, the birth of new technologies, the entry of emerging competitors, the intensification of industry competition and the uncertainty of business growth point cultivation. The details are as follows:

1. Downstream demand slowdown

As the developer of water treatment equipment, the company’s downstream customers are the engineering contractors of water environment treatment projects, and the final owners are local governments. Therefore, the company is in the upstream of the industry chain, and its business development is affected by the downstream demand. If the downstream demand slows down, it will have an adverse impact on the company’s business development.

2. Technology promotion fails to meet expectations

Rpir technology is independently researched and developed by the company’s core team. After the establishment of the company, it has been commercially applied and promoted. The technology promotion time is short and is currently in the initial promotion period. A ² O. MBR, MBBR and other sewage treatment technologies were born abroad and have been verified by long-term practice in sewage treatment projects abroad. They have competitive advantages such as scale advantage, customer advantage, promotion advantage and brand advantage. Although rpir technology has the characteristics of low investment and small land occupation, it also has some technical limitations, such as the cleaning and replacement cost of inclined pipe packing, the control accuracy of suspended solids in single ring section is less than that of MBR membrane filtration technology, and the cost of water distribution in a small amount of pipeline. Due to the cost of technology replacement, obvious first mover advantage of traditional technology, inertia of customer selection, different promotion subjects, long construction cycle of long-term projects, promotion efforts of the company need to be improved, and the technical indicators are only part of the factors considered by customers, rpir technology has a low market share compared with other sewage treatment technologies, and there is a certain gap in brand influence. If the company cannot further promote in the future
