Summary:A bstract We show that the messenger-matter couplings of Flavored Gauge Mediation Models can generate substantial stop mixing and new contributions to the stop masses, leading to Higgs masses around 126 GeV with sub-TeV superpartners, and with some colored superpartners around 1-2 TeV in parts of the parameter space. We study the spectra of a few examples with a single messenger pair coupling dominantly to the top, for different messenger scales. Flavor constraints in these models are obeyed by virtue of supersymmetric alignment: the same flavor symmetry that explains fermion masses dictates the structure of the matter-messenger couplings, and this structure is inherited by the soft terms. We present the leading 1-loop and 2-loop contributions to the soft terms for general coupling matrices in generation space. Because of the Higgs-messenger mixing induced by the new couplings, the calculation of these soft terms via analytic continuation requires careful matching of the high- and low-energy theories. We discuss the calculation in detail in the appendix.
