How to read "8x EBITDA," what it implies about the business

What Is a Valuation Multiple?

📋 What you're given

You're in an interview and the interviewer says: "You mention a company trades at '8x EBITDA.' What does that number actually mean, and what does it imply about the business?"

1. Task Overview

Task: explain what a valuation multiple actually represents, then use two similarly sized companies to show what a gap between their multiples implies in dollar terms.

Step 1: Given Data — Two Comparable Companies

Both companies generate the same EBITDA, but the market prices them very differently.

Line Item	Company A	Company B
EBITDA	$120.0m	$120.0m
EV/EBITDA Multiple	6.0x	9.0x

Step 2: Enterprise Value

Show Enterprise Value Formula

Enterprise Value = EV/EBITDA Multiple × EBITDA

Using this formula, compute Enterprise Value for both Company A and Company B.

Step 3: Valuation Premium

Show Valuation Premium Formula

Valuation Premium ($) = Enterprise Value (Company B) − Enterprise Value (Company A)
Valuation Premium (%) = Valuation Premium ($) / Enterprise Value (Company A)

Using this formula, compute how much more the market is valuing Company B versus Company A, in both dollar and percentage terms.

Step 4: What's Driving the Gap?

Before revealing the model answer, think about what could make investors consistently pay more per dollar of EBITDA for Company B than for Company A, even though both companies report the exact same EBITDA today.

💡 Model answer

Try answering out loud first — then reveal the model answer and compare.

Step 1: Enterprise Value

Line Item	Company A	Company B
EBITDA	$120.0m	$120.0m
EV/EBITDA Multiple	6.0x	9.0x
Enterprise Value	$720.0m	$1,080.0m

Enterprise Value (Company A) = 6.0x × $120.0m = $720.0m

Enterprise Value (Company B) = 9.0x × $120.0m = $1,080.0m

A valuation multiple like EV/EBITDA is really a shorthand for a full valuation: it compresses assumptions about growth, margins, risk, and capital intensity into a single number the market applies to a metric like EBITDA. Because both companies report identical EBITDA, the entire $360m gap in Enterprise Value comes from the multiple itself, not from the underlying financial metric.

Step 2: Valuation Premium

Valuation Premium ($) = $1,080.0m − $720.0m = $360.0m

Valuation Premium (%) = $360.0m / $720.0m = 50.0% (0.50)

The market is paying a 50.0% premium for Company B's operating business relative to Company A's, despite both generating the same EBITDA today. This premium is the practical signal interviewers want you to notice: a multiple by itself doesn't tell you whether a company is "cheap" or "expensive" — it tells you how much the market is willing to pay for a dollar of that company's EBITDA relative to its peers.

Step 3: What Typically Drives a Multiple Gap

Since both companies have identical current EBITDA, the higher multiple on Company B reflects differences the income statement alone doesn't show. The drivers interviewers most often expect you to name are:

Growth: higher expected EBITDA growth justifies paying more today for the same current EBITDA.
Margins and profitability trajectory: a business expected to convert more of its revenue into free cash flow over time supports a higher multiple.
Risk and cost of capital: lower business risk (more predictable, less cyclical cash flows) lowers the discount rate and mechanically raises the multiple.
Capital intensity: a company that needs less reinvestment (capex, working capital) to sustain its growth converts more EBITDA into free cash flow, which the market rewards with a higher multiple.
Quality and predictability of earnings: recurring, contracted revenue (e.g., subscription models) typically trades at a premium to lumpy or cyclical revenue.

Final Results

Company A Enterprise Value: $720.0m
Company B Enterprise Value: $1,080.0m
Valuation Premium: $360.0m (50.0%)

This is the starting point of any comparable-companies analysis: before applying a peer's multiple to a target company, you first need to work out whether the gap between multiples is justified by real differences in growth, margins, and risk — or whether it's a re-rating you shouldn't simply extrapolate.

Would you like to walk through a quick sanity check for whether a premium multiple like Company B's is justified, such as a growth-adjusted (PEG-style) multiple?

⚠️ Common mistakes

Treating a higher multiple as automatically "more expensive" or overvalued without asking what's driving the premium (growth, margins, risk).
Comparing EV/EBITDA multiples across companies with very different growth rates or capital structures without adjusting for those differences.
Confusing a valuation multiple with a market cap or share price comparison — multiples are ratios of Enterprise Value to a financial metric, not standalone prices.
Assuming multiples are static, ignoring that they compress or expand as growth expectations, risk, or market sentiment change over time.
Applying a peer group's average multiple mechanically without checking whether the target company's growth, margins, and risk profile actually resemble the peer set.
