What term describes a company that operates in countries other than its home country?

The term that describes a company operating in countries other than its home country is multinational. Multinational corporations (MNCs) are characterized by having business operations, offices, or factories in multiple countries. They typically engage in significant production, marketing, and management in more than one nation, allowing them to adapt their business strategies to various local markets while benefiting from efficiencies and resources on a global scale.

A global corporation refers to a company that operates on a worldwide scale, often with a standardized product offering in all markets. While similar to a multinational, it emphasizes a more integrated approach across markets.

International trade refers to the exchange of goods and services between countries and does not specifically denote the characteristics of a company or corporation.

Transnational corporations share some similarities with multinationals but often have a more decentralized approach, treating their international operations more like a network of subsidiaries rather than as a single unified entity.

Thus, "multinational" most accurately describes a company that conducts business in multiple countries.
