In this work, we study the impact of electroweak and Higgs precision measurements at future electron-positron colliders on several typical supersymmetric models, including the constrained minimal supersymmetric Standard Model (CMSSM), nonuniversal Higgs mass generalizations (NUHM1, NUHM2), and the seven-dimensional minimal supersymmetric Standard Model (MSSM7). Using publicly available data from the GAMBIT community, we postprocess previous SUSY global fits with additional likelihoods to explore the discovery potential of Higgs factories, such as the Circular Electron Positron Collider (CEPC), the Future Circular Collider (FCC), and the International Linear Collider (ILC). We show that the currently allowed parameter space of these models will be further tested by future precision measurements. In particular, dark matter annihilation mechanisms may be distinguished by precise measurements of Higgs observables.
