This week, 10 new companies completed domestic IPO coaching filing, with the semiconductor sector taking three seats.

Mars Finance News: On July 5, according to information disclosed on the CSRC website, during this week (June 29 to July 5), a total of 10 new companies obtained filing records for onboarding/investment-banking guidance for domestic issuance and listing. They are Zhejiang Deistai New Materials, Qingdao Haisen Hair Products, Jiangsu Jingying New Materials, Wuxi Kenonwei New Energy, Jiangsu Yingneng Microelectronics, Zhejiang Yitainuo Technology, Shengdak Semiconductor Technology (Shanghai), Nanjing Liancheng Technology, Sichuan AidiviXin Bio-Pharmaceutical, and Zetainfo Information Group.

Among them, three companies are in the semiconductor sector. Shengdak Semiconductor is a semiconductor testing equipment provider that has attracted investment from Hillhouse Capital and Semiconductor Investment—Yuan; it signed a guidance agreement in 2022 but did not submit application materials, and this time has restarted. Zetainfo is targeting domestic substitution for semiconductor CIM systems, while Yingneng Microelectronics focuses on power and analog ICs; both companies are filing for the first time.

There are also four companies making their first attempt to “break through.” Jingying New Materials’ business focuses on N-methylaniline, the core raw material for gasoline anti-knock agents. Kenonwei focuses on new-energy thermal management and components; Yitainuo is a national-level specialized and sophisticated “little giant” in the field of industrial automation pneumatic components, and Liancheng Technology is a provider of centralized network security control and management technology.

The remaining three companies have previously had unsuccessful IPO experiences. Deistai, a PVB film producer, applied for GEM/STAR Market listing three times in 2019, 2020, and 2023, but each time was unsuccessful. Haisen, a wig supplier, had its guidance terminated twice in 2023 and 2025. AidiviXin, a vaccine R&D and manufacturing company, submitted an application for a Main Board listing on the Hong Kong Exchanges and Clearing Limited in April 2021, but the process was not advanced.
