To participate in an ASX IPO, you typically need to have a brokerage account with a firm that offers IPO access. Your broker can provide you with the necessary information and guidelines on how to apply for shares in an IPO. It's important to carefully review the prospectus and understand the risks and terms associated with the IPO before making an investment decision.

The lead manager, also known as the underwriter, plays a crucial role in an ASX IPO. They are responsible for assisting the company in preparing for the IPO, determining the offering price, marketing the IPO to potential investors, and managing the allocation of shares. The lead manager helps ensure the smooth execution of the IPO process and facilitates the company's transition to being publicly traded.
