  We compute the massive gauge and scalar corrections to form factors in both
the Sudakov and threshold regimes up to and including two-loop orders. The
corrections are calculated for processes involving two external fermions and
scalars in the spontaneously broken SU(N)-Higgs model, examining a range of
composite operators. Our results are general, so we discuss how our form
factors are mappable from our model to the Standard Model and beyond. The
effective theory formalism deployed in our work extends previous studies based
on infrared evolution equations, which either neglect scalar contributions or
are restricted to the Sudakov regime.
