"That company trades at 8x EBITDA." It's one of the most common phrases in finance, and one of the least understood. A valuation multiple isn't just a price tag; it's a compressed summary of everything the market believes about a company's growth, profitability, risk, and capital needs, expressed as a single number.

What a Valuation Multiple Actually Is

A valuation multiple is a ratio that compares a company's value to a financial metric, such as EBITDA, revenue, or net income. The three most common multiples are:

  • EV/EBITDA (Enterprise Value to EBITDA): the most widely used multiple in investment banking, because it's independent of capital structure and tax jurisdiction. See What Is a Valuation Multiple? for a worked example.
  • EV/Revenue: used for companies that aren't yet profitable, common in high-growth technology and biotech valuations.
  • P/E (Price to Earnings): compares a company's share price to its earnings per share; unlike EV/EBITDA, it is affected by capital structure, since net income already reflects interest expense.

Multiples are a form of relative valuation: instead of building a full intrinsic value estimate like a Discounted Cash Flow model, you infer what a company should be worth from what the market is currently paying for similar businesses. For the full process of selecting peers and applying multiples, see our guide to Comparable Company Analysis.

Why Similar Companies Trade at Different Multiples

Here's the part that trips up most candidates in interviews: two companies can report the exact same EBITDA today and still trade at meaningfully different multiples. The multiple isn't pricing today's EBITDA, it's pricing the market's expectations about that EBITDA going forward. The main drivers are:

  • Growth: a company expected to grow its EBITDA faster typically commands a higher multiple, because investors are effectively paying today for cash flows that arrive in future years.
  • Margins and profitability trajectory: businesses expected to convert more of each revenue dollar into cash flow over time support richer multiples.
  • Risk and cost of capital: more predictable, less cyclical cash flows lower the discount rate applied to future cash flows, which mechanically pushes the multiple higher.
  • Capital intensity: a company that needs less reinvestment (capex, working capital) to sustain its growth keeps more of its EBITDA as free cash flow, which the market rewards.
  • Quality and predictability of earnings: recurring, contracted revenue (subscription models, long-term contracts) typically trades at a premium to lumpy or cyclical revenue.

Our case study What Is a Valuation Multiple? walks through exactly this scenario: two companies with identical $120m EBITDA trading at 6.0x and 9.0x respectively, and quantifies the 50% Enterprise Value premium that gap implies.

From Multiple to Enterprise Value

Once you have a multiple and the corresponding metric, computing Enterprise Value is mechanical:

Enterprise Value = Multiple × Metric (e.g., EV/EBITDA × EBITDA)

From there, bridging Enterprise Value down to Equity Value requires adjusting for net debt and other claims on the business, covered step by step in EV-to-Equity Bridge (Intro). If you're unclear on what Enterprise Value represents in the first place, start with What Is Enterprise Value? or our companion article, What Is Enterprise Value? A Plain-English Guide.

Common Mistakes When Reading Multiples

  • Treating a higher multiple as automatically "expensive" without asking what growth, margin, or risk assumptions justify it.
  • Comparing multiples across companies with very different growth rates or capital structures without adjusting for those differences.
  • Confusing a valuation multiple with a raw share price or market cap comparison.
  • Forgetting that multiples move over time as growth expectations, interest rates, and market sentiment shift, so a multiple observed today is not a fixed, permanent fact about a company.

Practice It

The best way to internalize how multiples work is to compute one yourself. Try What Is a Valuation Multiple?, a guided case that has you calculate the Enterprise Value premium between two comparable companies and reason through what's driving the gap.
