Recently, rumors that the relevant regulations issued informal window guidance to some investment banks and investment institutions and that they will raise the threshold for humanoid robot IPOs attracted market attention. I learned from interviews with various investment bankers that investment bankers have already received reminders from their companies about hard technology IPOs, including the robotics industry. If the industry is not prominent enough, the listing process may be affected. A leading brokerage firm said that investment bankers did not receive notifications in the form of window guidance; the relevant content was more aimed at compacting the sponsoring agency's front-end control responsibilities.
