They were at $1 one year ago and everybody was waiting for the Morpho protest to go away so they could immediately start shipping units to the TSA. It's mostly the government delays that made things so difficult, and the company's willingness to be optimistic with regard to them. And mine.
But yeah once they knew the pricing it seems hard to figure their internal plans to get out of the predicament other than a buyout, but I'm sure there were plenty of considerations we aren't even aware of today.
I think they always have been shooting for the moon - which includes a buyout option as well as other options, so they continue to hope that the $850m market is realistic. Drug detection, handheld, vortex, and still freight forwarders - all stuff that they still are putting much of their hopes and faith in but take time. More than anybody expected - including them, IMO.
