SPACs are chock full of fees to Wall Street.
When the SPAC goes public, it pays an IPO fee. The bank, having to comply with fewer regulations than in a traditional IPO, makes a healthy profit. When the SPAC negotiates a merger it pays M&A fees. When shareholders are presented with the merger and asked to vote that comes with a fee. If there is a PIPE, there are, of course, more fees.
Later, when the sponsors sell their stock, there will be brokerage fees for the block trade. And I assume, in the final stage of a SPAC’s lifecycle, there will be de-listing, liquidation and/or distressed debt fees.
