Extensions of GMSB models were recently explored to explain the recent reports of the Higgs boson mass around 124 - 126GeV. Some models predict a large mu term, which can spoil the vacuum stability of the universe. We study two GMSB extensions: i) the model with a large trilinear coupling of the top squark, and ii) that with extra vector-like matters. In both models, the vacuum stability condition provides upper bounds on the gluino mass if combined with the muon g - 2. The whole parameter region is expected to be covered by LHC at root s = 14TeV. The analysis is also applied to the mSUGRA models with the vector-like matters.
