The EBITDA margin is the ratio of EBITDA to revenues, expressed as a percentage. It measures operating profitability before depreciation, amortisation and financial items — one of the most widely used performance indicators in financial analysis, business valuation and sector benchmarking.

EBITDA margin reflects operational efficiency — a company's ability to convert revenues into available operating cash flow. It varies significantly by sector: scalable B2B SaaS reaches 20–40% at scale, while food distribution or construction typically shows 2–8%. These sector differences justify very different EBITDA multiples and must be accounted for in any comparative analysis.

In financial due diligence and valuation, EBITDA margin evolution over 3 to 5 years is carefully analysed to identify structural trends, mix effects (revenue composition changes), scale economies and non-recurring charges that may have artificially improved or depressed the margin. A structurally above-median sector margin is a valuation premium factor.

Example: a Swiss services SME shows revenue of CHF 8.0 million and EBITDA of CHF 1.2 million — accounting EBITDA margin of 15.0%. After normalisation (+CHF 150K management remuneration, +CHF 80K non-recurring charges), normalised EBITDA is CHF 1.43 million — normalised margin of 17.9%. Sector comparables: median 14%, Q3 18%. The normalised margin sits in the third quartile — justifying a slight premium on the median EBITDA multiple.

At Hectelion, we systematically analyse historical and normalised EBITDA margins in our Franco-Swiss valuation and due diligence mandates.
