White knight

A white knight is a person or company that comes to the rescue of a business facing a hostile takeover or financial trouble. They step in to acquire the struggling company, often at a favorable price, to protect it from an unwelcome buyer or to stabilize its situation. This strategic move helps preserve the company’s value and can prevent unwanted ownership changes. The term highlights their role as a benevolent or protective force, similar to a knight saving someone in distress.
