We claim that there is a one to one correspondence between NAdS2 spacetimes and dilatonic AdS2 black holes. We show that these have the same thermodynamics and can be described by the same states of 1D CFTs with the same central charge. In addition, we show that these are actually the same set of solutions since a field redefinition in the Schwarzian theory transforms its equation of motion into the time independent part of the bulk Einstein equation. The deformations of the AdS2 boundary as a function of the boundary time are exactly the conformal factor of the AdS2 black hole metric as a function of the radial bulk coordinate.
