Edig is a public company.
A tender offer would have to be made at a specific price, lets say $.50. If the majority of the shareholdes approved the transaction, then the price would equal $.50 times the number of shares, approximately 200 million, that`s 100 million dollars.
In addition, current debt, other types of shares and equity would be part of the acquired price.
If they want control of the company then one share more than half would give them voting power for board members, operating control, etc. The price would then be based on acquiring 100 million shares at the market price over a period of time. $.15 to ?
If they want a minority say in operations, then usually 5% of the outstanding shares may get you a board position.
Your question is simple, the answers are more complicated given exactly what the objectives would be.
Hope this helps some.
