  The Operator Product Expansion is a useful tool to represent correlation
functions. In this note we extend Conformal Regge theory to provide an exact
OPE representation of Lorenzian four-point correlators in conformal field
theory, valid even away from Regge limit. The representation extends
convergence of the OPE by rewriting it as a double integral over continuous
spins and dimensions, and features a novel "Regge block". We test the formula
in the conformal fishnet theory, where exact results involving nontrivial Regge
trajectories are available.
