Tips on major events

The issuer reminds investors to pay special attention to the following matters and risks of the company's issuance, and carefully read the text of the prospectus. 1、 The issuer is a biomedical industry company adopting the fifth set of listing standards

The issuer is a biomedical industry company adopting the fifth set of listing standards. The issuer reminds investors to pay attention to the following characteristics and risks of the company:

(I) no products are sold on the market, resulting in the company's non-profit and continuous loss

As of the signing date of this prospectus, all varieties of the company are in the R & D stage, have not carried out commercial production and sales, and have not realized sales revenue of drugs. The company has not made profits and has accumulated outstanding losses: December 31, 2018, December 31, 2019, December 31, 2020 and June 30, 2021, The company's accumulated outstanding losses were 400.6468 million yuan, 132.854088 million yuan, 97.30955 million yuan and 131.24856 million yuan respectively. In the future, the company is expected to continue to make losses, and the accumulated outstanding losses will continue to expand.

(II) large scale R & D investment is expected to continue in the future

During the reporting period, the company invested a lot of money in preclinical research, clinical trials and preparation for new drugs. In 2018, 2019, 2020 and January June 2021, the company's R & D expenses were 169071900 yuan, 363044800 yuan, 581329700 yuan and 261929800 yuan respectively. As of the signing date of this prospectus, the company's product pipeline has 15 varieties under research, and its development businesses such as preclinical research, clinical trials and preparation for new drugs before listing still need to continue large-scale R & D investment.

(III) there is uncertainty in the listing of main varieties under research

Due to the uncertainty of whether the research data at each stage meet the review and approval requirements (whether the review and approval requirements change or not) in the new drug R & D and marketing application stage, the company can not guarantee that the research data obtained from the varieties under research can meet the review and approval requirements, so as to ensure that the new drugs developed can be approved by the regulatory authority for marketing.

(IV) failure to make profits may result in termination of listing

The company will continue to invest in large-scale R & D in the next few years, and the corresponding varieties of the company's R & D expenditure will be treated as expenses before obtaining the approval for the listing of new drugs. Therefore, the unprofitable state after listing is expected to continue, and the accumulated outstanding losses may continue to expand.

If the company triggers the financial status specified in article 12.4.2 of the Listing Rules of Shanghai Stock Exchange Kechuang board shares in the fourth full fiscal year since the listing date, that is, the audited net profit (including retroactive restatement) before or after deducting non recurring profits and losses is negative, and the operating income (including retroactive restatement) is less than 100 million yuan, Or the audited net assets (including retroactive restatement) are negative, which will cause the company to trigger delisting conditions. If the company's main product research and development fails or fails to obtain drug listing approval after listing, and the company has no other business or products meet the requirements of item 5 of article 2.1.2 of the Listing Rules of science and Innovation Board of Shanghai Stock Exchange, the company will also trigger delisting conditions. According to the measures for continuous supervision of listed companies on the science and Innovation Board (Trial), if the company touches the criteria for termination of listing, the listing of shares shall be terminated directly, and the procedures for suspension, resumption and re listing shall no longer apply. 2、 Progress of the issuer's main product pipeline, market competition and corresponding risks
