Deferred Underwriting Fee

The deferred underwriting fee is a structural feature that aligns the underwriter's incentives with deal completion. In a standard SPAC IPO, the total underwriting commission is 5.5% of gross proceeds, split into two components: 2% paid immediately at IPO closing and 3.5% deferred and held in the trust. The deferred portion is only released to the underwriter when the SPAC successfully closes a business combination.

For a $200 million SPAC IPO, this means $4 million is paid upfront and $7 million sits in the trust as a deferred obligation. The deferred fee is reflected in the trust account balance but is not available for distribution to shareholders upon redemption — it comes off the top at closing. If the SPAC liquidates, the underwriter forfeits the deferred fee entirely, incentivizing them to assist with target sourcing and deal execution.

The deferred fee has been a source of tension in the SPAC market. When redemptions are high, the deferred fee consumes a larger percentage of the remaining cash, reducing the proceeds available for the combined company. In response, some underwriters have agreed to reduce or waive their deferred fees to help deals close — particularly in situations where the SPAC sponsor is a repeat client. Other underwriters have negotiated alternative arrangements, such as converting part of the deferred fee into equity in the combined company.

SpacDesk tracks deferred underwriting fees for every SPAC, including the original committed amount, any negotiated reductions, and the actual payment at closing. The fee is factored into the net-cash-to-target calculation that determines how much money actually reaches the operating business.
