# What Is Follow-On Offering?

> A follow-on offering is a public company sale of additional shares after its IPO—primary shares raise new capital for the issuer; secondary shares sell existing holders' stock.

**A follow-on offering** (often called an FPO) is a registered sale of stock by a public company after its initial public offering—either issuing new primary shares to raise capital or selling secondary shares on behalf of existing shareholders.

### How it works

Investment banks underwrite **primary** follow-ons where proceeds fund operations, M&A, or debt paydown—diluting existing holders unless offset by growth. **Secondary** follow-ons let founders, employees, and VC funds sell registered shares into the market, increasing float without company proceeds. Mixed offerings combine both. Pricing typically discounts recent trading to attract buyers; roadshows resemble IPO lite.

Post-IPO venture investors monitor [lock-up](/glossary/lock-up) expirations—first tradable windows often coincide with secondary follow-ons or block trades. Issuers file shelf registrations (S-3) to act quickly when windows open. Market reception affects future capital access and employee morale if stock sells off on heavy supply.

Distinct from [follow-on offering (fund)](/glossary/follow-on-offering-fund), which refers to LP fundraising in private markets.

### Why it matters

- **Founders:** Time primary offerings when growth story is strong; coordinate secondary sales with board policy on insider selling signals.
- **Investors:** Follow-ons realize public marks into cash; large secondaries can pressure price—coordinate syndicate selling when possible.

### Common mistake

Confusing ATM (at-the-market) programs with full follow-on offerings. ATMs dribble sales over time; traditional follow-ons are discrete, marketed events with different disclosure.

## FAQ

### What is a follow-on offering in simple terms?

After a company is public, it can sell more shares on the stock market— either to raise new company cash (primary) or let early investors sell theirs (secondary).

### Why does follow-on offering matter?

It affects public float, stock price, and insider liquidity. VC-backed founders and funds plan follow-ons around lock-up release and market windows.
