We study the near-horizon geometry of four-dimensional charged static black holes in heterotic string theory and analyze the possible dynamical emergence of dual IR conformal field theory. We find that when we turn on mass and charges in such a way that extremal black holes have classically vanishing horizon area, the near horizon develops an AdS3 throat and when we combine the low energy limit with vanishing Newton coupling constant, the system has a dual conformal field theory description. We compare our results with c-extremization and the Kerr/CFT predictions.
