Minimum buyout
The clawback to 51% costs Sibanye 173 million by my math. That equates to 5.58 million per 1%. To buy the additional 49% at that valuation costs 273 million, for a total of 446 million USD. That is the absolute minimum. But there is no way a vote would approve such a low price. 446 173 million shares outstanding is $2.58 USD.
