Abstract
We compute the spectrum of extremal nonBPS black holes in four dimensions by studying supergravity on their AdS 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/nCFT correspondence and by comparing with dimensional reduction from AdS/CFT 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.
