What is EBITDA — and Why It Matters in M&A
EBITDA — Earnings Before Interest, Tax, Depreciation, and Amortisation — is the most commonly used metric to value businesses in mid-market M&A. If you are considering selling your company, understanding what EBITDA is, why buyers use it, and what normalised EBITDA means is essential preparation before entering any M&A process.
What EBITDA measures
EBITDA measures the operating profitability of a business before the effects of its capital structure (interest), tax position, and non-cash accounting charges (depreciation and amortisation). The logic is that it provides a cleaner view of operating performance than net profit — because it strips out items that vary between businesses based on how they are financed and structured, not how well they operate. A business that is owned outright carries no interest expense; a business that is heavily leveraged does. EBITDA normalises for this, allowing buyers to compare businesses on a like-for-like basis and to model their own capital structure onto the acquired business.
How buyers use EBITDA to value businesses
The most common valuation method for mid-market businesses is the EBITDA multiple: Enterprise Value = EBITDA × Multiple. The multiple varies by sector, growth rate, margin quality, and the competitive dynamics of the process. A technology business might trade at 12–18x EBITDA; a manufacturing business might trade at 5–8x EBITDA. Understanding your sector's prevailing multiple range — and the factors that push your business to the high or low end of that range — is central to understanding what your business is worth.
Normalised EBITDA vs. reported EBITDA
Normalised EBITDA — also called adjusted EBITDA — is what buyers actually use. It adjusts the reported EBITDA to reflect the true run-rate profitability of the business under new ownership, excluding one-time items, non-recurring costs, owner-specific expenses, and other items that will not recur. Common add-backs include: above-market owner salaries that will be replaced by a market-rate CEO; one-time legal or advisory costs; rent paid to the owner at above-market rates; and depreciation on non-business assets. The normalisation schedule — the detailed reconciliation from reported EBITDA to normalised EBITDA — is one of the most scrutinised documents in any M&A process.
Why EBITDA add-backs get scrutinised
Add-backs are legitimate and expected — but they must be defensible. Buyers and their Quality of Earnings accountants will pressure-test every line. An owner salary replacement that seems aggressive, a one-time cost that has recurred for three years, or an add-back that cannot be supported with documentation will not hold up. Sellers who are conservative and well-documented in their normalisation schedule run cleaner processes; sellers who are aggressive face expensive late-stage negotiations or deal re-pricing.
EBITDA vs. EBITDAC, EBITDAL, and other variants
You will encounter variants of EBITDA in specific contexts. EBITDAL (adding back lease payments) is common in hospitality, retail, and other lease-heavy businesses — it allows comparison of businesses that own their properties versus those that lease. EBITDAC appeared during COVID to adjust for extraordinary impacts. These variants exist to provide cleaner comparison across different business structures, but their use must be disclosed and explained clearly in any marketing materials.
What buyers care about beyond EBITDA
EBITDA is the starting point, not the end point. After establishing normalised EBITDA and applying a sector multiple, buyers then adjust for: the quality of that EBITDA (recurring vs. one-time), capex requirements (businesses with heavy reinvestment needs are worth less), working capital requirements, debt and debt-like items on the balance sheet, and any specific risk factors. Understanding these adjustments helps sellers see their business the way buyers see it — and prepare accordingly.
Key takeaways
EBITDA measures operating profitability before interest, tax, depreciation, and amortisation — it is the standard valuation metric in mid-market M&A.
Buyers apply an EBITDA multiple to determine enterprise value — the multiple varies by sector, growth rate, and quality.
Normalised (adjusted) EBITDA is what actually gets valued — it removes one-time costs, owner-specific expenses, and non-recurring items.
Add-backs must be conservative and fully documented — buyers and their QoE accountants will scrutinise every line.
EBITDA is the starting point — buyers also adjust for working capital, capex, debt, and revenue quality to arrive at equity value.
