Exclusive production of light vector mesons in deep inelastic scattering iscalculated at next-to-leading order in the dipole picture in the limit of highphoton virtuality. The resulting expression is free of any divergences andsuitable for numerical evaluations. The higher-order corrections are found tobe numerically important, but they can be mostly captured by thenonperturbative fit parameters describing the initial condition for thesmall-$x$ evolution of the dipole scattering amplitude. The vector mesonproduction cross section is shown to depend only weakly on the mesondistribution amplitude and the factorization scale. We also presentphenomenological comparisons of our result to the existing exclusive $\phi$ and$\rho$ production data from HERA and find an excellent agreement at highvirtualities.
