We present a quantitative analysis of the electromagnetic pion form factor inthe light-cone sum rule approach, including radiative corrections andhigher-twist effects. The comparison to the existing data favors the asymptoticprofile of the pion distribution amplitude and allows to estimate thedeviation: $(\int du/u \phi_\pi(u))/ (\int du/u \phi^{\rm as}_\pi(u))=$1.1$\pm$ 0.1 at the scale 1 GeV. Special attention is payed to the precisedefinition and interplay of soft and hard contributions at intermediatemomentum transfer, and to matching of the sum rule to the perturbative QCDprediction. We observe a strong numerical cancellation between the soft (endpoint) contribution and power suppressed hard contributions of higher twist, sothat the total nonperturbative correction to the usual pQCD result turns out tobe of order 30% for $Q^2\sim 1$ GeV$^2$.Comment: to appear in Phys. Rev. D., one equation (Eq.(51) in old version) is  eliminated and some new text added. None of the results are change
