A Golden Share is a type of share that gives its shareholder veto power over changes to the company's charter. It holds special voting rights, giving its holder the ability to block another shareholder from taking more than a ratio of ordinary shares.This makes it an important tool for investors who want to protect their interests in a company and keep it from being taken over by another party. While there are some benefits to having a golden share, such as preventing hostile takeovers, it can also be used as a way for shareholders to hold onto control of a company even when they no longer have the majority stake.
