A subsidiary is a company owned by another company, called a “parent company” or “holding company.” The holding company controls the subsidiary by appointing its choice of directors and managers. To be a holding company, it must own a “controlling interest” in the subsidiary, meaning it owns at least 51% of that company’s shares. If the parent owns 100% of the subsidiary, it’s called a “wholly owned” subsidiary. Read the holding company definition for more information.

The subsidiary exists as a separate legal entity within the conglomerate. Therefore, a subsidiary can require more paperwork and taxation and potentially faces more red tape than a single business. Operating a subsidiary can also leave the business owner with a decreased focus on the original business. Finally, if the two companies have a conflict of interest, such as a duplicative product or market, it can cause management clashes.
Just as the holding company is sometimes called the “parent,” the subsidiary company is sometimes called the “daughter company.” While there can be some variations in terminology, these names typically refer to the same entities.
A subsidiary and its parent can be corporations or limited liability companies (LLCs). Here are some famous examples of subsidiary companies and their parents:
Many companies around the world use subsidiaries to control and manage large, diversified businesses.
