Many models as e.g. Composite Higgs models feature the existence of heavyvvector-like quarks. Mixing effects between SM fields and the heavy states,vwhich can be quite large in case of the top quark, lead to deviations from the SM. A Higgs boson mass at 125 GeV implies for many Composite Higgs Models that some the new fermions, especially the ones mixing with the top quark, are within the reach of the LHC . In this talk, the effects of top partners and bottom partners on Higgs physics will be discussed. The analysis takes into account constraints arising from electroweak precision tests and direct searches of new vector-like fermions.
