What would be the point of buying a company without integrating it?

Companies make acquisitions for a variety of motives, as explained in the Strategy section, and not every deal involves integration.

The degree and nature of integration necessary after an acquisition  can range from a sweeping combination to a simple change in ownership status. If the acquirer has a strategic reason for buying the company, some form of integration will be necessary for success. If the acquirer’s reason for buying a firm is financial, however, integration may not be particularly helpful.
