424(b) prospectus
The final prospectus filed after a registration becomes effective, carrying the terms the offering actually used.
Updated 2026-07-26
A registration statement is what the company proposes; the 424(b) filing is what was actually offered. It carries the final price, the final share count and the completed terms, and it is filed within days of the offering being priced.
The letter and number after 424(b) identify which rule the filing was made under, which distinguishes, for example, a final prospectus for a completed offering from one used for a continuous shelf programme.
For any question about the terms of an offering, this document is the authority, and an earlier registration statement is not.
