A book runner is an individual responsible for the distribution and underwriting of securities under an initial public offering (IPO). The book runner is the main point of contact for investors who wish to purchase securities from the issuing company. To facilitate this, the book runner will typically coordinate the timely, effective, and efficient distribution of the securities with market makers, guaranteeing both buyers and sellers have access to the securities.

In the context of an IPO, the book runner is typically a financial institution or broker, who acts on behalf of the issuing company, underwriter, and other parties involved in a public offering. Acting as an intermediary, the book runner bears most of the responsibility for organizing a successful public offering. As the main agent in an IPO, the book runner conducts the majority of the negotiations between the issuer, the investment advisor, and the underwriters. At the same time, the book runner also acts as the intermediary between the issuer and the market makers who will provide liquidity to the newly issued securities.

The book runner is also typically responsible for setting the IPO price, managing the offer and distribution of securities, and ensuring all regulatory requirements are in place before the start of any trades. In addition, the book runner will typically perform the duties of a middleman when it comes to collecting payments from investors and distributing the proceeds to the issuer and the underwriters.

The book runner’s role is to maximize the offering’s profitability, manage the investor demand and guarantee the proceeds are returned to the issuing company in a timely fashion. In order to do so, they will work closely with the issuer to ensure the offering is well-structured, distributed, and marketed. Typically, the book runner will develop a comprehensive sales strategy and pricing analysis, in order to increase the chances that the offering is successful.

In exchange for their services, the book runner will typically receive a financial compensation from the issuing company, either from an ongoing fee or as commission from the transaction. In some cases, book runners may only offer their services if the offering is sufficient enough to generate a certain level of revenue. Nonetheless, their services are often essential to the success of an IPO, and their due diligence greatly contributes to the issuance price and smooth execution of the transaction.
