Cash flow fade refers to the progressive and structural decline in free cash flows projected over a valuation horizon, driven by the erosion of a company's competitive advantage as competition intensifies over time. In DCF modelling, the fade rate translates the convergence of margins and growth rates toward sector median levels, avoiding the unrealistic assumption of perpetual outperformance. It is particularly relevant for high-growth technology companies and businesses with temporarily elevated returns that cannot be sustained indefinitely.

‍

Example: a Swiss SaaS company currently shows 40% ARR growth and a 30% EBITDA margin. The DCF model applies a 5-year fade: growth converges from 40% to 10%, and margin from 30% to 18%, reflecting anticipated competitive pressure. This fade reduces the terminal value by 22% versus a model assuming perpetual maintenance of current performance — a significant and more defensible adjustment.

At Hectelion, cash flow fade is systematically integrated into DCF models for high-growth companies to produce more conservative and defensible valuations.
