We establish the future stability of nonlinear perturbations of a class of homogeneous solutions to the relativistic Euler equations with a linear equation of state p = Kρ on exponentially expanding Friedmann-Lemaître-Robertson-Walker spacetimes for the equation of state parameter values 1/3 < K < 1/2.
