A parent company is a corporation that owns enough voting stock in another company, known as a subsidiary, to control its policies and management. This ownership allows the parent company to influence the subsidiary's operations while maintaining separate legal identities. Parent companies can provide resources, support, and strategic direction to their subsidiaries, which can help them grow and succeed in their respective markets. Examples of parent companies include Alphabet Inc., which owns Google, and Procter & Gamble, which has multiple well-known brands under its umbrella.
