The null results of the LHC searches have put strong bounds on new physicsscenario such as supersymmetry (SUSY). With the latest values of top quark massand strong coupling, we study the upper bounds on the sfermion masses inSplit-SUSY from the observed Higgs boson mass and electroweak (EW) vacuumstability. To be consistent with the observed Higgs mass, we find that thelargest value of supersymmetry breaking scales $M_{S}$ for $\tan\beta=2$ and$\tan\beta=4$ are $\mathcal{O} (10^{3}\, {\rm TeV})$ and $\mathcal{O}(10^{1.5}\, {\rm TeV})$ respectively, thus putting an upper bound on thesfermion masses around $10^{3}\, {\rm TeV}$. In addition, the Higgs quarticcoupling becomes negative at much lower scale than the Standard Model (SM), andwe extract the upper bound of $\mathcal{O}(10^{4}\, {\rm TeV})$ on the sfermionmasses from EW vacuum stability. Therefore, we obtain the PeV-Scale Split-SUSY.The key point is the extra contributions to the Renormalization Group Equation(RGE) running from the couplings among Higgs boson, Higgsinos, and gauginos. Webriefly comment on the lifetime of gluinos in our study and compare it withcurrent LHC observations. Additionally, we comment on the prospects ofdiscovery of prompt gluinos in a 100 TeV proton-propton collider.
