It's possible that they explored all acquisition possibilities they could find without the world knowing about their situation, and that the only company or companies who could reach acceptable terms to acquire them didn't have the network links to find out that Bench was acquirable until the news broke that they were shutting down.
Obviously not an ideal situation, both parties (if an acquisition is indeed happening) would prefer to have been able to do it before Bench's announcement, but there's simply no way to let every single person & company in the world who might consider acquiring them know what's on the table without the information being public knowledge too.
