The parent and the subsidiary do not necessarily have to operate in the same locations or operate the same businesses. Not only is it possible that they could conceivably be competitors in the marketplace, but such arrangements happen frequently at the end of a hostile takeover or voluntary merger. Also, because a parent company and a subsidiary are separate entities, it is entirely possible for one of them to be involved in legal proceedings, bankruptcy, tax delinquency, indictment or under investigation while the other is not.

yes
