Dual-Class Share Structure

A corporate structure where a company issues classes of shares with different voting rights, often concentrating power with founders.

A dual-class share structure is a corporate governance framework where a company issues multiple classes of common stock, each carrying different voting rights. Typically, one class of shares is sold to the public and carries standard voting power (such as one vote per share), while another class is reserved for company founders, executives, or early insiders and carries super-voting power (such as ten or more votes per share). In some cases, public shares may carry no voting rights at all. This structure is commonly observed in high-growth industries, particularly technology, where founders argue that concentrated control protects them from short-term market pressures and hostile takeovers. This insulation is intended to allow management to focus on long-term strategic goals. Investors can identify these structures by reviewing a company's initial public offering prospectus or annual proxy statements, which detail the distribution of voting power relative to economic ownership. For retail investors, dual-class structures present significant governance risks. Because voting power is concentrated, public shareholders have little to no influence over board elections, executive compensation, or major corporate transactions like mergers and acquisitions. This lack of accountability can lead to a principal-agent problem, where insiders make decisions that benefit themselves at the expense of minority shareholders. Consequently, some institutional investors and index providers discount or exclude dual-class companies from their portfolios.

Company A goes public with two classes of stock. Class A shares are sold to the public, representing 90% of the total outstanding shares but carrying 1 vote per share (90 million total votes). Class B shares are held entirely by the founder, representing 10% of the total outstanding shares but carrying 10 votes per share (100 million total votes). The founder controls 100 million out of 190 million total votes, giving them 52.6% of the voting power despite owning only 10% of the company's economic equity.
