Underwriting Syndicates and the Gross Spread

A company raising $500 million in an IPO does not sell shares to the public one investor at a time — it sells the entire block to a group of investment banks, who then turn around and resell it to institutional and retail investors. That group is the underwriting syndicate, and the fee they earn for taking on this job is the difference between what they pay the company and what they sell the shares for: the gross spread.

Why a syndicate, not one bank

A single bank rarely wants to hold the full risk of a large offering — if demand turns out weaker than expected, whoever bought the deal from the company is stuck holding unsold shares. Spreading the deal across several banks spreads that risk. One bank leads the process (the lead underwriter or bookrunner), setting price and allocating shares, while others in the syndicate commit to selling a portion and share in the fee.

Worked example

A company sells 20 million new shares in an IPO at $25.00 per share to the public, but the syndicate buys the shares from the company at $23.25 — a gross spread of $1.75 per share, a common range being roughly 5–7% of the offer price for a US IPO.

1. Total raised from investors. $20{,}000{,}000 \times 25.00 = 500{,}000{,}000$, or $500 million.
2. Total paid to the company. $20{,}000{,}000 \times 23.25 = 465{,}000{,}000$, or $465 million.
3. Gross spread, in dollars. $500{,}000{,}000 - 465{,}000{,}000 = 35{,}000{,}000$, or $35 million, split among the syndicate.
4. As a percentage of the deal. $1.75 / 25.00 = 0.07$, or 7%, in the typical range.

That $35 million is then divided: a small slice as a flat management fee to the lead bank for running the process, a larger slice as the underwriting fee compensating the syndicate for the risk of buying shares it might not fully resell, and the largest slice, the selling concession, paid out to whichever bank in the syndicate actually places each block of shares with an investor.

What this means in practice

The gross spread is why banks compete hard to lead large offerings — it is a direct, sizeable fee on the total amount raised, and the lead bank typically keeps a disproportionate share for running the process and taking the most risk. It also explains a structural incentive worth watching: because the underwriter is paid on the deal getting done and getting done smoothly, its interests in setting the offer price are not perfectly aligned with the issuing company's interest in raising the maximum amount possible, which is part of why IPOs are frequently priced below where they end up trading on the first day.
