Preferred stock is a class of company ownership that carries rights senior to common stock, such as priority on payout, and it is the standard instrument investors receive in a priced venture round. Founders and employees hold common; investors hold preferred.
Founders care because the terms attached to preferred stock decide who gets paid first, who controls key decisions, and how much founders keep in an exit.
How preferred stock is created
Under Delaware law, a corporation may issue one or more classes or series of stock with different rights. DGCL Section 151(a) allows the powers, designations, preferences, and rights of each class or series to be set in the certificate of incorporation, or fixed by the board of directors by resolution when the certificate authorizes it. That is how a company creates Series Seed, Series A, and later series of preferred stock, each with tailored terms.
Key rights attached to preferred stock
Preferred stock bundles several rights. The most important ones are these.
A liquidation preference gives preferred holders priority to get their money back before common holders on a sale or wind-down. Participating preferred stock lets the holder take that preference and then share in the rest. Dividends may accrue at a stated rate under DGCL Section 151(c), though early-stage dividends are often non-cumulative and rarely paid in cash.
Conversion rights let preferred convert into common stock, usually at a defined ratio, under DGCL Section 151(e). Anti-dilution protection can adjust that conversion ratio if the company later sells shares at a lower price.
Voting and protective rights of preferred stock
Preferred stock also carries control terms. DGCL Section 151(a) permits full, limited, or no voting powers for a class or series. In venture deals, preferred holders often get protective provisions. These are veto rights over specific actions, like selling the company or issuing more senior stock.
The mix of economics and control makes preferred stock the center of any priced fundraising negotiation. Read every right in the charter before you agree to a new series.
