Underwriting Fees & Economics

Underwriters earn the difference between the price they pay the company and the price investors pay, known as the gross spread. Mid-sized US IPOs have commonly carried a gross spread around 7%, while very large deals often negotiate lower percentages.

Key Takeaways

• Spreads fall as deal size rises.
• The spread pays for risk, distribution, and advice.
• Greenshoe covers up to 15% additional shares.
• Total offering costs are disclosed in the filing.

The Gross SpreadOther CostsThe GreenshoeSpread ComponentsFAQRelated

01

The Gross Spread

The spread is traditionally split into a management fee, an underwriting fee, and a selling concession. The split reflects who leads, who takes risk, and who sells shares to investors.

02

Other Costs

Companies also pay legal, accounting, printing, listing, and filing fees. SEC registration fees and FINRA fees apply. Total costs are disclosed in the prospectus and Part II.

03

The Greenshoe

The over-allotment option lets underwriters sell up to 15% more shares than the base deal. If the stock trades well, they exercise it and the company receives more proceeds. If it trades poorly, they cover the short by buying in the market, which supports the price.
