Dual-Class Share Structure

A **dual-class share structure** is a capital arrangement in which a company issues two or more classes of common stock, each with different voting power. The most common pattern gives founders or early insiders Class B shares with ten or more votes per share, while public investors buy Class A shares with one vote each. Some companies, such as Google's parent Alphabet, even have a third class with no voting rights at all.

The economics of all classes are usually identical with respect to dividends and liquidation, but the voting differential lets founders maintain control even after diluting their economic stake well below 50%. This insulates long-term strategy from quarterly market pressure but also reduces accountability to outside shareholders.

Dual-class structures are heavily concentrated in US technology IPOs. Index providers like S&P, MSCI, and FTSE Russell have responded by limiting or excluding companies with weak voting rights from major indices. Many exchanges, such as the Hong Kong and Singapore exchanges, now permit dual-class listings under specific conditions, including sunset clauses that convert super-voting shares to ordinary shares after a fixed period or upon founder departure.

Founders meet dual-class structures when designing the cap table for a high-growth company they expect to take public, when negotiating with VC investors who often resist disproportionate voting rights at the seed stage but accept them at later rounds, and when drafting bylaws to include sunset clauses. Investors should look for the voting ratio, class transfer mechanics, and sunset terms in any dual-class IPO prospectus, since these features determine how long the founder can maintain control.
