AFAIK - there's always a premium on a buy-out/purchase. I'll try to simplify as much as possible. If 100 people (shareholders) have 100 apples (outstanding shares) and the current market rate is $10 (stock price) each, it means that when someone wants to buy all 100 apples in one go, you can jack up the price (20% premium) because all of the people (shareholders) relinquish control and therefore give up their position for a premium. (there's way more nuances here, but basically this is what happens when supply is static and demand for totality exists)
