It depends upon how many minority interests are out there. If ownership is completely dispersed among multiple small shareholders, I could see potential investors not being amenable as they could potentially have a difficult time acquiring the entire company should they chose to do so in the future.

I agree with blacksqr though, if they want you to sell, the offer better come with a premium.

I haven't done anything amazing like a lot of these people, but I sure enjoy reading about them.
