We use a combination of quark-antiquark and $B^{(*)}K$ interpolating fieldsto predict the mass of two QCD bound states below the $B^*K$ threshold in thequantum channels $J^P=0^+$ and $1^+$. The mesons correspond to the b-quarkcousins of the $D_{s0}^*(2317)$ and $D_{s1}(2460)$ and have not yet beenobserved in experiment, even though they are expected to be found by LHCb. Inaddition to these predictions, we obtain excellent agreement of the remainingp-wave energy levels with the known $B_{s1}(5830)$ and $B_{s2}^*(5840)$ mesons.The results from our first principles calculation are compared to previousmodel-based estimates. More recently the D0 collaboration claimed the existenceof an exotic resonance $X(5568)$ with exotic flavor content $\bar{b}s\bar{d}u$.If such a state with $J^P=0^+$ exists, only the decay into $B_s\pi$ is openwhich makes a lattice search for this state much cleaner and simpler than forother exotic candidates involving heavy quarks. We conclude, however, that wedo not find such a candidate in agreement with a recent LHCb result.
