That is what you assume when you look to take a company private.

Think about it this way: The current market price represents the amount the shareholders who least value their shares would be willing to sell them for. As you want to acquire more, the price is going to go up, not down.

That's pretty irrelevant if it only represents 10% of the total equity, though. It's not like you, as a retail investor who owns a few shares of a company, have any say in whether it gets acquired.

SoftBank values continuing to hold the other 90% of the shares more than the market price or they’d be selling more.
