Not so for a foreign company Most US investors know there are many reasons for a foreign company to stay on the sheets and there are many large and famous companies that are still pink sheet stocks. For example VW. Neisle, Nissan, BASF. There are also some like Toyota who have the parent listed on Pink Toyof. and then Toyota of America listed on a full exchange.

Here is a list of the top ten Pink sheet companies.
