What Is EBITDA?
EBITDA stands for Earnings Before Interest, Taxes, Depreciation, and Amortisation. As Investopedia notes, it’s the most commonly referenced profitability metric in M&A transactions because it provides a standardised view of a company’s operating performance, stripped of factors that vary between companies due to financing decisions, tax jurisdictions, and accounting policies rather than operational quality.
The formula is straightforward:
EBITDA = Net Income + Interest + Taxes + Depreciation + Amortisation
Or equivalently:
EBITDA = Operating Income (EBIT) + Depreciation + Amortisation
Why EBITDA Matters in M&A
EBITDA serves as the primary valuation benchmark in the vast majority of M&A transactions. When deal professionals say a company “trades at 8x” or was “acquired for 12x,” they’re referring to the enterprise value-to-EBITDA multiple.
Comparability
Different companies have different capital structures (debt vs. equity), operate in different tax jurisdictions, and follow different depreciation schedules. EBITDA strips these differences away, allowing buyers to compare the operating profitability of two companies on an apples-to-apples basis.
A SaaS company in Singapore and a SaaS company in Sydney might have very different net income figures due to tax rates, depreciation of different asset bases, and different financing arrangements. Their EBITDA figures, however, reflect the same thing: how much cash the operations generate.
Proxy for Cash Flow
EBITDA approximates a company’s operating cash flow — the cash generated by the business before investment in growth, debt service, and taxes. While it’s not a perfect cash flow measure (it ignores working capital changes and capital expenditures), it’s a useful starting point for assessing how much cash a buyer can expect from the business.
Valuation Multiples
Enterprise value (EV) divided by EBITDA produces the EV/EBITDA multiple — the single most used valuation metric in M&A. Understanding this multiple is central to any M&A valuation guide, as it allows deal professionals to:
- Compare a target’s valuation to comparable public companies
- Benchmark against precedent transactions in the same sector
- Assess whether a proposed purchase price represents fair value
Adjusted EBITDA
In M&A, the EBITDA figure used for valuation is almost never the raw EBITDA from the income statement. Instead, buyers and sellers negotiate “adjusted EBITDA” — a figure that adds back or removes items that don’t reflect the company’s go-forward operating performance (Corporate Finance Institute).
Common Adjustments
Owner compensation. Private company owners often pay themselves above or below market rates. Adjusted EBITDA normalises compensation to market levels.
One-time expenses. Litigation costs, restructuring charges, relocation expenses, and other non-recurring items are typically added back because they won’t continue under new ownership.
Related-party transactions. Companies that lease property from the owner or pay management fees to related entities need adjustments to reflect arm’s-length costs.
Revenue or expense timing. If the company received a large one-time contract or incurred unusual expenses in the most recent period, EBITDA is adjusted to reflect normalised performance.
Run-rate adjustments. If the company made a significant change recently — a new product launch, a major hire, a facility closure — the historical EBITDA may not reflect the go-forward run rate. Pro forma adjustments capture the impact of these changes.
The Quality of Earnings Report
In most M&A transactions, the buyer commissions a quality of earnings (QoE) report from an accounting firm to validate the seller’s adjusted EBITDA as part of the M&A due diligence checklist. The QoE report scrutinises every adjustment, evaluates revenue quality and sustainability, and assesses working capital normalisation.
The difference between the seller’s adjusted EBITDA and the QoE-validated EBITDA can be significant — and it directly impacts the purchase price. A company marketed at “8x EBITDA” where the QoE report reduces EBITDA by 15% is effectively being purchased at 9.4x.
EBITDA Multiples by Sector
EBITDA multiples vary significantly by sector, reflecting differences in growth rates, capital intensity, competitive dynamics, and risk profiles.
| Sector | Typical EV/EBITDA Range | Key Drivers |
|---|---|---|
| SaaS / Enterprise Software | 15-30x | Recurring revenue, high margins, scalability |
| Technology Services | 10-18x | Revenue visibility, margin profile |
| Healthcare Services | 10-16x | Regulatory moats, demographic tailwinds |
| Financial Services | 8-14x | Asset quality, regulatory capital |
| Consumer / Retail | 7-12x | Brand strength, market position |
| Industrials / Manufacturing | 6-10x | Asset base, cyclicality |
| Business Services | 8-14x | Recurring revenue, customer retention |
These ranges are indicative. Actual multiples depend on company-specific factors: growth rate, margin profile, customer concentration, market position, and management quality. For a deeper look at how multiples are applied, see our guide on valuing a business for sale.
In Asia Pacific, multiples tend to vary by market maturity. Australian mid-market companies trade at multiples comparable to US benchmarks. Southeast Asian companies may trade at lower multiples but with higher growth rates. Japanese companies often trade at discounted multiples relative to Western peers, partly due to historical capital allocation practices — though this gap is narrowing as corporate governance reforms take effect.
EBITDA Limitations
While EBITDA is the dominant M&A metric, it has well-known limitations that sophisticated buyers consider.
Ignores Capital Expenditure
EBITDA doesn’t account for capital expenditure (capex) — the investment required to maintain and grow the business. A manufacturing company with high capex requirements generates less free cash flow than its EBITDA suggests. Capital-light businesses like software companies don’t have this problem, which partly explains their higher multiples.
Ignores Working Capital
Changes in working capital — accounts receivable, inventory, accounts payable — can significantly affect actual cash generation. A fast-growing company with increasing receivables may have strong EBITDA but weak cash flow.
Doesn’t Reflect Debt Burden
By definition, EBITDA excludes interest expense. A highly leveraged company may have attractive EBITDA but limited cash available to equity holders after debt service. This is why enterprise value (not equity value) is divided by EBITDA for valuation purposes.
Can Be Manipulated
Adjusted EBITDA is inherently subjective. Sellers have incentive to maximise adjustments; buyers have incentive to minimise them. The negotiation around adjustments is often where significant value is won or lost in an M&A process.
EBITDA in Practice: What Deal Teams Focus On
When evaluating a company’s EBITDA for M&A purposes, experienced deal teams look beyond the headline number:
- EBITDA margin trajectory — is the margin expanding, stable, or contracting?
- Revenue quality underlying EBITDA — is revenue recurring, contractual, or project-based?
- Customer concentration — does a small number of customers drive a large percentage of EBITDA?
- Adjustment magnitude — if adjustments exceed 20-30% of reported EBITDA, scrutinise heavily
- Capex requirements — what percentage of EBITDA must be reinvested to maintain the business?
- Conversion to free cash flow — what’s the EBITDA-to-FCF conversion rate?
These factors determine not just the EBITDA multiple a company deserves, but whether the EBITDA figure itself is reliable as a basis for valuation and transaction pricing.
