The measure itself
EBITDA takes operating profit and adds back depreciation and amortisation, producing earnings before interest, tax, depreciation and amortisation. The intent is comparability: it strips out the effects of financing choices, tax positions and historical asset purchases, leaving something closer to the underlying operating engine. Valuation multiples, lending covenants and earn-out targets are routinely set against it.
Why the number carries deals
When a business is priced at a multiple of EBITDA, every extra euro of EBITDA is worth eight or ten at completion. That arithmetic explains most of what happens to the metric during a sale process. It also explains what a buyer must keep in view: EBITDA ignores capital expenditure, working capital movements, and the interest and tax that will still have to be paid, so a capital-hungry business can post healthy EBITDA while consuming cash. The multiple prices the engine; it says nothing about the fuel bill.
