Supermajority Rules: Impact on Corporate Finance and Shareholder Votes

A supermajority is a voting requirement that obliges roughly 67% to 90% of shareholders to approve major corporate actions, making certain decisions harder to pass than under a simple majority. The article traces the concept’s roots to Roman juries and medieval elections, noting that a two-thirds supermajority rule exists for electing a pope even after Pope John Paul II attempted changes in 1996. In modern corporate finance, supermajorities are typically used for major moves such as mergers and acquisitions, leadership changes, and decisions about going public via an investment bank or going private. Non-vote items like dividend declarations can be handled by the board. While supermajority support can add stability, it can also slow strategy and create deadlocks if ownership is concentrated.
