Abstract: The CMS collaboration reported an intriguing ∼ 3σ (local) excess at 96 GeV in the light Higgs-boson search in the diphoton decay mode. This mass coincides with a ∼ 2σ (local) excess in the $b\overline{b}$ final state at LEP. We briefly review the proposed combined interpretations for the two excesses. In more detail we review the interpretation of this possible signal as the lightest Higgs boson in the 2 Higgs Doublet Model with an additional real Higgs singlet (N2HDM). We show which channels have the best prospects for the discovery of additional Higgs bosons at the upcoming Run 3 of the LHC.
