Future Higgs factories can reach impressive precision on Higgs property measurements. In this talk, we explore its sensitivity to new physics models at the electron-positron colliders.

In particular, we focus on Type-II Two Higgs Double Models and MSSM as illustrative examples. We perform a global fit to various Higgs search channels to obtain the 95% C.L. constraints on the model parameter space. We compare the sensitivity of various future Higgs factories, namely Circular Electron Positron Collider, Future Circular Collider-ee and International Linear Collider.  

We also show the complementarity between Higgs precision and Z-pole measurements, as well as direct searches for new particles at future pp colliders.
