We calculate the branching ratios and CP-violating asymmetries for $B_s^0 \to\pi^0 \eta^{(\prime)}$ decays in the perturbative QCD (pQCD) factorizationapproach here. We not only calculate the usual factorizable contributions, butalso evaluate the non-factorizable and annihilation type contributions. ThepQCD predictions for the CP-averaged branching ratios are $BR(B_s^0 \to \pi^0\eta) \approx 0.86 \times 10^{-7}$ and $BR(B_s^0 \to \pi^0 \eta') \approx 1.86\times 10^{-7}$. The pQCD predictions for the CP-violating asymmetries are$A_{CP}^{dir}(\pi^0 \eta)\sim -4.5 % $, $A_{CP}^{dir}(\pi^0 \eta')\sim -9.1% $,$A_{CP}^{mix}(\pi^0 \eta)\sim -0.2%$, and $A_{CP}^{mix}(\pi^0 \eta')\sim 27.0%$but with large errors. The above pQCD predictions can be tested in the nearfuture LHC-b experiments at CERN and the BTeV experiments at Fermilab.Comment: 15 pages 3 eps figure
