Secondary offering
A sale of shares after the IPO. If the company issues new ones it raises money and dilutes holders; if an existing holder sells, the company gets nothing.

A secondary offering is a sale of shares after the IPO, and the label covers two quite different events.
- The company issues new shares. It raises money, and every existing holder's stake is diluted. Whether that is good depends entirely on what the money buys.
- An existing large holder sells shares they already own. The share count does not change and the company receives nothing. What it signals is that an informed holder wanted out.
A shelf registration is the mechanism that makes this quick: register once, then sell in tranches over the following years. A large shelf filing is a company reserving the option to dilute, which is worth noticing even before it is used. See shares outstanding.

- IPO — A company's first sale of stock to the public. It converts private ownership into something anyone can buy, and it is the moment a price becomes public.
- Shares outstanding — The share count that converts a whole-company equity value into a per-share figure. Getting it wrong scales every valuation by exactly the same error.
- Primary market — Where securities are sold for the first time and the money reaches the company. Every share trades here exactly once.
