GSB provides software for file transfer. To put the size of that order in perspective, their quarterly revenue has typically been in the $3.7M-$4M range. I'm guessing that this single order pushes their 2009 diluted EPS to the $0.15 ballpark with more upside possible. At $0.89 IMO the stock is quite undervalued.
They have a strong balance sheet with BV of $0.43/share and no debt.
They also released some new products in mid to late 2008 which could provide some nice additions to the bottom line.
I plan on following up with more DD in the coming days.
