This proceeding contribution presents a selected number of studies performed by the ATLAS and the CMS experiments on b-hadron spectroscopy. Both collaborations have a rich b-hadron physics program on exploiting the large cross section of b-hadrons at the high energies of the LHC. For the ATLAS collaboration, we report the observation of an excited $B_c^{+}$ meson state and the search for a structure in the $B_s\pi^{\pm}$ invariant mass spectrum. For the CMS collaboration, recent results in the study of the $B^{+}\to J/\psi \Lambda p$ decay and observation of two excited Bc states and measurement of the $B_c^{+}(2S)$ mass.
