Simple Definition

The investment bank (or consortium of banks) that prices an IPO, allocates shares, and stands behind the listing. Underwriters buy shares from the company at a negotiated price and resell them to investors.

Why It Matters

Underwriters are the gatekeepers of an IPO. They set the price range during the roadshow, allocate shares to favored institutional clients, and provide post-IPO support (research coverage, market-making). The reputation of the lead underwriter signals credibility — having Goldman Sachs or Morgan Stanley lead is a different signal than a regional broker. They also often impose lockup terms.

Key Points

  • Lead underwriters typically take 4–7% of the IPO proceeds as their fee.
  • The 'greenshoe option' lets underwriters issue up to 15% more shares if demand is strong.
  • Underwriter allocation favors institutional clients with long-term relationships — retail allocation programs (Robinhood IPO Access, Fidelity) exist but are smaller and uncertain.
