The holographic QCD prediction for the pion distribution amplitude (DA) phi(hol)(u) is used to compute the pion spacelike electromagnetic form factor F-pi(Q(2)) within the QCD light-cone sum rule method. In calculations the pion's renormalon-based model twist-4 DA, as well as the asymptotic twist-4 DA are employed. Obtained theoretical predictions are compared with experimental data and with results of the holographic QCD.
