Since this year, A-share companies have been actively split and listed. On December 8, Ningbo Ocean, a subsidiary of Ningbo Port, was successfully listed on the main board of Shanghai Stock Exchange. So far, according to incomplete statistics by the reporter, 10 listed companies have successfully split their subsidiaries to be listed in A-shares during the year. In addition, more than 30 companies have disclosed their split plans or related intentions this year. In this regard, many experts said in an interview with the Securities Daily that the spin off and listing can enable relevant business sectors to obtain independent development opportunities, broaden financing channels, and further enhance the company's brand influence and market competitiveness. With the increase of diversified companies in the A-share market and the gradual maturity of the market trading and regulatory environment, the number of cases of split listing will continue to increase in the future, but enterprises should not blindly follow the trend, and should prudently promote relevant matters according to their own conditions. In recent months, Qibin Group, Han's Laser, Weichai Power and other companies have issued plans for the listing of spin off subsidiaries, and Zhongtian Technology and other companies have issued advisory announcements on the planned spin off of subsidiaries. Among them, Han's Laser and Weichai Power have not put forward the split plan for the first time. As the leader of laser equipment, Han's Laser disclosed the plan to split its subsidiary, Shanghai Han's Fuchengde Technology Co., Ltd. (hereinafter referred to as "Shanghai Fuchengde"), to be listed on the GEM on November 19. Han's Laser said that after this spin off and listing, Shanghai Fuchengde will strengthen the investment and development of core technologies, accelerate the ramp up of production capacity, and maintain the innovative vitality in the field of semiconductor and pan semiconductor automatic transmission equipment manufacturing. Before that, Han's CNC, a subsidiary of Han's Laser, had landed on the GEM on February 28 this year, and the GEM listing application of another subsidiary, Shenzhen Han's Closed Test Technology Co., Ltd., was also accepted by Shenzhen Stock Exchange in September this year. As for the reason why A-share companies are active in the spin off listing, Qin Yuan, a special researcher of the Institute, said in an interview with the Securities Daily that it is mainly due to the continuous improvement of the spin off listing system. In December 2019, the CSRC issued the Several Provisions on the Pilot Domestic Listing of the Subsidiary of the Spin off of a Listed Company, which is the standard for the spin off listing; At the beginning of 2022, the CSRC issued the Rules for the Splitting of Listed Companies (for Trial Implementation), integrating the previous domestic and overseas splitting listing rules, unifying domestic and overseas regulatory requirements, and clarifying and improving the conditions for the splitting. Qin Yuan believes that "the resources and capabilities of a single enterprise are limited, and the split listing can better broaden financing channels and improve cash flow, so it gradually becomes one of the ideal choices for enterprises to improve their own performance and overall market value." Xu Minsui, a partner of Chengluo Capital, believes that diversification of enterprise operation and development is the main reason for the active spin off listing. "Many listed companies, after a certain period of development, will have diversified operations, complicated equity structure and other situations. Spin off listing can introduce investors of different natures, and parent companies and subsidiaries can concentrate more resources to accelerate business development. Therefore, spin off listing meets the development needs of such listed companies." The reporter found that at this stage, most A-share companies use the Science and Technology Innovation Board and the Growth Enterprise Market as the destinations for spin off and listing.
