IPO (Initial Public Offering)

An IPO (Initial Public Offering) is the process of a private company offering shares to the public for the first time, becoming a public company. IPOs allow companies to raise capital and create a market for their shares.

Formula

IPO Valuation = IPO Price × Shares Offered

If a company offers 50 million shares at $20 each, valuation = $1 billion.

Example

Meta (formerly Facebook) IPO'd in May 2012 at $38/share, raising $16.5 billion. Google IPO'd in 2004 at $85/share. Stripe, SpaceX, and others remain private. Once a company IPOs, its shares trade on exchanges (NASDAQ, NYSE), and anyone can buy them.

How to Interpret It

• Company raises capital: At IPO, the company gets cash from share sales; secondary trading doesn't directly fund the company.
• Early investor liquidity: Founders, venture capitalists, and early employees can finally cash out.
• Public valuation: The market now determines price through daily trading, not private investors' assessments.
• Lock-up period: Usually 6 months post-IPO, insiders can't sell; when this expires, supply increases and price often drops.
• IPO pop: First-day trading often results in price surge (especially underpriced IPOs); performance after that is unpredictable.

Limitations

• IPO prices are often underpriced; underwriters deliberately price IPOs low to ensure demand, benefiting early buyers but not the company.
• The first few months of trading are volatile; IPOs are often highly speculative.
• Some IPOs are cash grabs by early investors (Facebook, Snapchat) with little subsequent outperformance.
• Earnings quality can deteriorate post-IPO as management focuses on meeting quarterly estimates.
