We consider the Standard Model (SM) with the addition of a$\mathrm{U(1)^\prime}$ gauge symmetry and a complete fourth family of quarksand leptons which are vector-like with respect to the full$\mathrm{SU(3)_C}\times \mathrm{SU(2)_L} \times \mathrm{U(1)_Y}\times\mathrm{U(1)^\prime}$ gauge symmetry. The model provides a unified explanationof experimental anomalies in $(g - 2)_\mu$ as well as $b \rightarrow s \ell^+\ell^-$ decays. We find good fits to the deviations from the SM, while at thesame time fitting all other SM observables. The model includes a new $Z^\prime$gauge boson, a $\mathrm{U(1)^\prime}$-breaking scalar, and vector-like leptonsall with mass of order a few $100$ GeV. It is consistent with all currentlyreleased high energy experimental data, however, it appears imminently testablewith well designed future searches. Also precision flavor experiments,especially more accurate direct determinations of CKM matrix elements, wouldallow to probe the best fit points.
