It's not really a matter of who said what. It's a matter of what is reasonable looking at the economics.

Sandisk has a Market Cap of 3.9 billion and the offer was approx. 6 billion, or about 1.5 times the current value.

Edig has a Market Cap of 34 million and at $21.00 a share that computes to approx 6.0 billion or 176 times the current value.

Sandisk has a Market Cap of 115 times the edig Market Cap, doesn't make sense to offer the same price or ask for the same amount.

Any investment decision is a matter or the expected ROI including the time value of money.
