The light-cone distribution amplitudes (LCDAs) serve as importantnon-perturbative inputs for the study of hard exclusive processes. In thispaper, we calculate ten LCDAs at twist-2 for the S-wave and P-wave $B_c$ mesonsup to the next-to-leading order (NLO) of the strong coupling $\alpha_s$ andleading order of the velocity expansion. Each one of these ten LCDAs isexpressed as a product of a perturbatively calculable distribution and auniversal NRQCD matrix-element. By use of the spin symmetry, only two NRQCDmatrix-elements will be involved. The reduction of the number ofnon-perturbative inputs will improve the predictive power of collinearfactorization.
