  We present a family of exact planar hairy neutral black hole solutions in
extended supergravity with Fayet-Iliopoulos (FI) terms. We consider a model
where the magnetic part of FI sector vanishes and obtain the superpotential at
finite temperature in analytic form. Then, we discuss the thermodynamics and
some holographic properties of these solutions. We regularize the action by two
different methods, one with gravitational and scalar counterterms and the other
using the thermal superpotential as a counterterm, and compute the holographic
stress tensor. We also construct the $c$-function of the corresponding RG flow
and obtain an exact holographic $\beta$-function for this model.
