What is EBITDA and why do bankers use it as the go-to valuation metric?

Q: What is the difference between EBIT and EBITDA?

EBIT (Earnings Before Interest and Taxes) includes depreciation and amortization as expenses, reflecting the cost of asset usage. EBITDA adds back D&A to approximate cash operating profit before reinvestment. EBITDA is more commonly used in M&A valuation multiples, while EBIT better reflects ongoing capital requirements for asset-intensive businesses.

Q: Why is EBITDA used as the basis for the most common valuation multiple in M&A?

EBITDA strips out financing decisions (interest), tax jurisdiction (taxes), and non-cash accounting charges (D&A), making it comparable across companies regardless of capital structure, geography, or asset age. This makes EV/EBITDA the standard valuation multiple in M&A, especially in LBOs where PE firms replace the target's capital structure.

Q: What is the biggest weakness of using EBITDA?

EBITDA ignores that assets eventually need replacing. By adding back depreciation, it pretends that capital expenditures are optional. Capital-intensive businesses like manufacturing or telecom can look artificially profitable on an EBITDA basis while requiring massive reinvestment to maintain operations. Free cash flow is a more complete measure of cash generation.

Q: Why do PE firms focus on EBITDA in LBO analysis?

PE firms want to know the target's cash generation capacity before layering on acquisition debt. Since they will replace the target's existing capital structure with heavy leverage, the seller's interest expense is irrelevant. EBITDA shows what the core operations produce independent of current financing, making it the starting point for debt capacity and returns analysis.

"EBITDA suggests that capital expenditures, interest, and taxes are not expenses. Which, of course, they are." — Seth Klarman

Concept

EBITDA is Earnings Before Interest, Taxes, Depreciation, and Amortization. It strips out financing decisions (interest), tax jurisdiction (taxes), and non-cash accounting charges (D&A) to approximate a company's core operating cash generation. It's not GAAP. It's not on the income statement. It's a proxy for operating performance that lets you compare companies regardless of how they're financed or where they're domiciled.

Intuition

EBITDA exists because bankers needed a quick way to compare companies with different financing, different tax situations, and different accounting histories. It answers: "If I owned this business free and clear, with no debt and no historical baggage, roughly how much cash would it spit out from operations?"

It's not perfect. It ignores maintenance capex, working capital needs, and the reality that assets wear out. But it's fast, it's comparable, and it's the basis for EV/EBITDA—the single most important valuation multiple in M&A.

Components

Why Remove Interest?

What It Is

Interest expense reflects how a company is financed, not how well it operates. Two identical businesses with different debt levels will have different net incomes but the same EBITDA.

The Logic

When comparing Company A (all equity) to Company B (50% debt), their profitability looks different at net income. But that's a capital structure choice, not an operational one. Stripping interest lets you see the underlying business.

Key Consideration

This is why EBITDA matters in LBOs—PE firms want to know the cash generation before they layer on acquisition debt.

Why Remove Taxes?

What It Is

Tax expense depends on jurisdiction, NOL carryforwards, and tax planning. It varies wildly between companies for reasons unrelated to operations.

The Logic

A company in Ireland pays ~12.5% corporate tax. One in the US pays ~21%. Comparing their net incomes directly penalizes the US company for geography, not performance.

Key Consideration

Post-acquisition, a buyer often restructures the target's tax position anyway. EBITDA shows what the business earns independent of its current tax situation.

Why Remove Depreciation & Amortization?

What It Is

D&A are non-cash charges that allocate historical capital expenditure costs over time. Depreciation applies to tangible assets (PP&E). Amortization applies to intangibles (patents, customer relationships from acquisitions).

The Logic

No cash leaves the company when you record D&A—the cash left years ago when you bought the asset. Adding it back gives a cleaner view of current cash generation.

Key Consideration

This is EBITDA's biggest weakness. D&A isn't truly "free"—the company will need to replace those assets eventually. Capital-intensive businesses can look artificially profitable on an EBITDA basis.

Interview Script

EBITDA stands for Earnings Before Interest, Taxes, Depreciation, and Amortization. It strips out financing decisions, tax jurisdiction, and non-cash accounting charges to approximate a company's core operating cash generation, which makes it useful for comparing companies regardless of capital structure. It's the basis for EV/EBITDA, the most important valuation multiple in M&A, though it does ignore maintenance capex and working capital needs.
