The recent CMS results on B^0_s spectroscopy are presented. The search for exotic state X(5568) decaying into B^0_s pi^{+-} is reported together with the studies of P-wave B_s meson states Bs1(5830)0 and Bs2(5840)0, including the observation of the Bs2(5840)0 -> B0 K0s decay. The results are based on the data sample collected by the CMS experiment at the LHC in proton-proton collisions at sqrt(s)=8 TeV, corresponding to an integrated luminosity of 19.7 fb^-1.
