My point still stands even if it's equity. PE/corp buyers may not care about buying out the very small minority stock holders, that is the point I 'm making.

Lets say you've got

Founder A 25% - Voting, Founder B 25% - Voting, Investor A 10% - Voting, Investor B 15% - Voting, Investor C 8% - Voting.

Former Employee A 0.5% - Non Voting, Former Employee B 0.4% - Non Voting, Employee C+ 0.2-0.3% each all Non Voting.

If say Big Co want's to buy the company why do they care about buying out former Employee B? If they can pickup the two founders and the three investors, thats enough for complete practical control.
