Abstract The presence of the 125-GeV Higgs boson in the particle spectrum of the minimal supersymmetric (SUSY) standard model (MSSM) implies that the SUSY breaking scale has to be larger than $$1\text{ TeV}$$ . In this case some fine-tuning of the MSSM parameters is needed to get so light Higgs state. In a certain part of the parameter space of the simplest extension of the MSSM—next-to-minimal supersymmetric Standard Model (NMSSM) the restrictions on $$M_{S}$$ are weaker than in the MSSM. This part of the NMSSM parameter space leads to some predictions for the spectrum of the Higgs bosons which are considered in this paper. The possible manifestations of new Higgs states at the LHC experiments are also discussed. The analysis performed in this article indicates that light exotic states in the $$U(1)$$ extensions of the MSSM may result in the nonstandard decays of the 125-GeV Higgs boson.
