  We compute the spectrum of extremal nonBPS black holes in four dimensions by
studying supergravity on their AdS$_2\times S^2$ near horizon geometry. We find
that the spectrum exhibits significant simplifications even though
supersymmetry is completely broken. We interpret our results in the framework
of nAdS$_2$/nCFT$_1$ correspondence and by comparing with dimensional reduction
from AdS$_3$/CFT$_2$ duality. As an additional test we compute quantum
corrections to extremal black hole entropy on the nonBPS branch and recover
results previously determined using very different methods.
