Good Question. It depends on whether someone is trying to buy the 51% or the 49% Selling the 49%: 49 by what I assume the definition of "worth" to be. Selling the 51%: If: You think the buyer can run the company better than you Then: 51 If: You think the buyer can run the company tolerably well Then: 60 - Extra money to account for loss of control. Note that now the $$$ worth of the company will be changed such that the new worth is 117 If: Don't think the buyer can run the company Then: Forget it, no price Unless: You need to sell. Then I guess negotiate what you can get. EDIT: I guess this is basically a formula based on the expected future worth of the company, but I can't think of the expression at the moment.
