They also said that "A wide range of results remains possible for 2013." They also said that hitting their outlook depends on closing too large and very complex deals in the end of the year. I am very doubtful this will happen given the present state of the budget.
The 2 large deals you are referring to were pushed out of Q3 into Q4.
"We did not achieve the financial results we were anticipating for the third quarter as a couple of large acceptances shifted out of the quarter and we now expect to have both of them completed in the fourth quarter"
"Our revenue expectations for the year remain intact" A wide range of results remains possible for 2013. A significant portion of our expected fourth quarter revenue is dependent on several large systems which are currently anticipated to be accepted in late Q4"
