I can't find them in there, but does that conclusively mean the aren't registered?
Yes. If they aren't listed, they aren't registered.
"...spent 25 mil in the first year to become financially compliant in th us"
Says nothing about MSB (virtual currency traders didn't even need MSB registration in the "first year" of MtGox). Doesn't specify what they did to "become financially compliant". Even if they were financially compliant in 2010 the FinCen declaration on March 2013 was a pretty huge deal, probably the biggest legal event in Bitcoin history (for US based bitcoin related companies).
