Here is a link to the document (warning, it's a ~400 page pdf):
OMB Report Pursuant to the Sequestration Transparency Act of 2012 (P. L. 112–155)
Overall, it is clear that Federal contractors will be slammed very hard, across the board. We might see some reaction in the next few days, as businesses begin to project the toll. One has to remember that a cut in Federal labor often corresponds to a much larger contractor cut; we saw this recently during the recent FAA budget debacle.
The OMB document provides precious little specific detail; one merely sees, for example, that the National Institutes of Health (NIH) stands to lose $2.5B (see page 82 of the OMB document linked above). The agencies and contractors need much more detail, and there will be much more preparatory work required within individual agencies over the coming weeks.
I expect all contractors to take a very large hit, and it appears that Federal and State (VA, MD) credit downgrades appear almost unavoidable at this point.
From an investment perspective, I would steer well clear of contractors to federal agencies. Here is a link to the top 100 federal contractors, in terms of net contract value:
