What is Preferred stock? Definition, Formula & Benchmarks

What is preferred stock?

Preferred stock is the share class investors receive in a priced round, carrying rights that common stock lacks, a liquidation preference, anti-dilution protection, and often board seats or veto rights. It sits ahead of common in the payout stack, so preferred holders get paid first in an exit. Founders and employees hold common.

Worked example

Series A investors putting in $10M receive Series A preferred stock with a 1x liquidation preference and a board seat, ranking ahead of founders' common shares.

Why it matters for fast-growing companies

Every priced round adds a new series of preferred, each with its own preferences and rights, and they stack. That stack determines who gets paid what in an exit and who controls key decisions. Founders should track the full preference stack and protective provisions, because they shape both economics and control.

Frequently asked questions

What rights does preferred stock have that common doesn't?+

Typically a liquidation preference (paid back first in an exit), anti-dilution protection, pro-rata rights to invest in future rounds, information rights, and protective provisions, vetoes over decisions like selling the company or issuing senior stock. Preferred may also carry board seats. These rights are negotiated in the term sheet.

Does preferred stock convert to common?+

Yes. Preferred typically converts to common, usually automatically at an IPO or when holders choose to at an exit. Investors convert when their as-converted common value exceeds their liquidation preference, meaning a big outcome. In smaller exits they keep the preference instead, taking their guaranteed payout off the top.
