A future e+e- circular collider (FCC-ee) may provide a unique probe of the electron Yukawa coupling through Higgs boson production on resonance. Motivated by this exciting possibility, we examine a simple model which can result in O(10) modifications of the Higgs coupling to electrons. The model can also lead to deviations in the electron anomalous magnetic moment, ge-2, which at present shows a +2.2σ or -3.7σ deviation, implied by differing precision determinations of the electromagnetic fine structure constant. The electron ge-2 can be a forerunner for FCC-ee discoveries which, as we elucidate, may not be accessible to the high-luminosity LHC measurements. A simple extension of our model can also account for the current deviation in the muon gμ-2.
