Summary: We show how the \(S\)-matrix of an extended theory of gravity defined by its three-point amplitudes can be constructed by demanding factorisation. The resultant \(S\)-matrix has tree amplitudes obeying the same soft singularity theorems as Einstein gravity including the sub-sub-leading terms.
