Golden Share financial

"appointed by the Brazilian Federal Government, holder of the Golden Share"

A golden share is a special class of stock that gives its holder the ability to block or control certain major decisions — like sales, mergers, or changes to a company’s charter — even if they own only a small percentage of the shares. It matters to investors because it can limit takeover bids, reduce the influence of ordinary shareholders, and change a company’s strategic options much like a master key that can lock or unlock key doors.
