IPO Pricing Night

Pricing night is the evening the IPO is finalized. After the market closes, the company and lead underwriters agree on the price and share count, sign the underwriting agreement, and the SEC registration becomes effective. Trading begins the next morning.

Key Takeaways

• The final price is set after the roadshow, once the book of orders is reviewed.
• The underwriting agreement is signed, making the commitment binding.
• SEC effectiveness is requested for the pricing window and the final prospectus follows.
• Allocations are sent to investors, and trading starts the next morning.

Common questions

Why price after the market closes?

It lets the book reflect the full day's information and gives time for allocations and filings before trading opens.

Can the deal fall apart on pricing night?

Yes. If demand is weak, the company can postpone or reprice, though doing so after launching carries cost and reputational effects.
