The CP-even and CP-odd scalar states of the two-Higgs-doublet model (THDM) and the Higgs sector of theMinimal Supersymmetric StandardModel (MSSM), with properties which could lead to the 750 GeV excess in the γγ invariant mass distribution, are studied. It is shown that THDM and MSSM are viable in explaining the observed excess without additional assumptions only when the alignment and decoupling limits break down. If the origin of the excess is not in a Higgs sector, regions of the MSSM parameter space are separated where the lightest CP-even Higgs boson is identical to the Standard Model scalar.
