IPO (Initial Public Offing), or Initial Public Offering, refers to the first time a company (issuer) offers its shares to the public.
The capital market serves as the core of the modern financial system and represents the most efficient financing channel and powerful capital operation platform for enterprises. As the sole pathway for companies to enter the capital market, IPO subjects companies to stricter information disclosure and corporate governance requirements. This, to some extent, reduces the risk profile of companies while maximizing corporate value and enhancing shareholder returns.
