  The paper concerns parameterized equilibria governed by generalized equations
whose multivalued parts are modeled via regular normals to nonconvex conic
constraints. Our main goal is to derive a precise pointwise second-order
formula for calculating the graphical derivative of the solution maps to such
generalized equations that involves Lagrange multipliers of the corresponding
KKT systems and critical cone directions. Then we apply the obtained formula to
characterizing a Lipschitzian stability notion for the solution maps that is
known as isolated calmness.
