Well the announcement you are referring to is the layoffs and quarterly losses and not the letter of intent.

This news solidified what the street thought about Blackberry's recent BB10 sales. Its sort of like saying this house was worth 1 million before the fire. How can someone get away with paying on 300,000 for it now that its been burned to the ground.

The answer is that given the new news( poor sales, layoffs, write downs of inventory, etc) that BB is no longer worth 10.50/share.

So to answer you question, yes they probably will get that price.

It was selling for $8.26 this morning--the drop you're seeing is from last week after they announced they lost $1,000,000 over the previous 90 days and were laying off 4,500 people. The buyout announcement is what provided the small boost this afternoon.
