Dual-Class Share Structure
A Dual-Class Share Structure is a corporate equity arrangement in which a company issues two (or more) classes of common stock with different voting rights, typically granting founders or insiders shares with superior votes while public investors hold shares with limited or no voting power.
In a standard dual-class structure, founders or controlling shareholders hold Class B shares carrying 10 votes per share, while public shareholders receive Class A shares carrying 1 vote per share. This allows founders to retain voting control even after selling down their economic ownership below 50%, insulating the company from hostile takeovers and activist pressure.
Dual-class structures have proliferated in the US technology sector. Alphabet (Google), Meta (Facebook), Snap, Lyft, and dozens of other prominent companies went public with structures that effectively let their founders control the outcome of any shareholder vote indefinitely, regardless of how much stock was sold to the public. High-profile international listings — including some Chinese technology companies listed on US exchanges — have also used weighted voting structures.
Advocates argue that dual-class structures allow visionary founders to make long-horizon investments without being forced to optimize for quarterly earnings. Critics — including major institutional investors, ISS, and Glass Lewis — argue they undermine shareholder democracy, entrench founders regardless of performance, and remove the market for corporate control as a disciplining mechanism.
Index inclusion has become a major flashpoint. MSCI, S&P Dow Jones Indices, and FTSE Russell have all adopted restrictions on dual-class companies in their flagship indices, concluding that including them would underweight shareholder rights in passive portfolios. Some dual-class companies are excluded entirely; others are included with reduced index weights.
Sunset provisions — automatic conversion of superior-vote shares to one-share-one-vote after a specified period or upon the departure of the founder — are increasingly required by stock exchanges and supported by governance advocates as a compromise between founder control and long-run governance accountability.
