  The renormalization group flow of soft supersymmetry breaking masses is
sensitive to the field contents of the theory one considers. We point out that
the addition of extra vector-like matter fields to the minimal supersymmetric
standard model raises the masses of squarks and sleptons relative to those of
gauginos. We discuss its phenomenological implications. Besides an obvious
effect to the superparticle mass spectrum, we find that radiative corrections
from heavier stop loops increase the lightest CP-even Higgs boson mass. We also
discuss impact on models with no-scale boundary conditions. It turns out that,
unlike the minimal case, staus can become heavier than a B-ino like neutralino,
which is cosmologically favored.
