A best-efforts offering requires underwriters to try to sell securities but does not guarantee the issuer will sell the full amount.
A best-efforts offering is a term used in finance and investment banking to describe an agreement between an underwriter and an issuing company in which the underwriter commits to making their best effort to sell as many shares as possible from the new issuance, without guaranteeing the sale of all the shares. Unlike a firm commitment offering where the underwriter buys all the shares and resells them to the public, in a best-efforts offering, any unsold shares remain the responsibility of the issuing company.
In an all-or-none (AON) offering, the issuer stipulates that the securities offering must be completely sold for the deal to proceed. If the underwriter fails to sell all of the shares, the offering is called off, and no shares are sold.
Also known as a “part” or “partial” best-efforts offering, a mini-maxi offering sets a minimum threshold of shares that must be sold for the offering to be considered successful. If this minimum is met, the underwriter will continue to sell up to a maximum amount of shares specified.
The primary risk associated with best-efforts offerings lies with the issuing company, which may not sell all the intended shares, potentially affecting the amount of capital raised.
Underwriters typically earn a commission on the shares sold. In a best-efforts offering, this commission can provide incentives for the underwriter to sell as many shares as possible.

Q1: What is the main difference between a best-efforts offering and a firm commitment offering?
A: The main difference lies in the underwriter’s liability. In a best-efforts offering, the underwriter does not guarantee the sale of all shares, nor do they purchase unsold shares. In a firm commitment offering, the underwriter buys all the shares and resells them, assuming any unsold shares’ financial risk.
Q2: Why might a company choose a best-efforts offering over a firm commitment offering?
A: Companies might choose a best-efforts offering when the risk of unsold shares is high, and they prefer to avoid the higher underwriting fees associated with a firm commitment. It is also favorable during uncertain market conditions.
Q3: How does an all-or-none offering work within the best-efforts framework?
A: In an all-or-none best-efforts offering, the deal proceeds only if all the shares are sold. If the underwriter fails to sell the total number of shares, the offering is canceled, and investors are refunded.
