Comparable Company Valuation: EV/EBITDA and P/E Explained
Comparable company valuation estimates value by relating a business’s financial performance to the pricing of similar businesses. Instead of forecasting every future cash flow, it applies a supported market multiple to a consistently defined financial measure. The arithmetic is simple; choosing genuinely comparable companies and matching the numbers takes judgment.

Two multiples, two valuation layers
| Multiple | Calculation | Value produced when applied |
|---|---|---|
| EV/EBITDA | Enterprise value ÷ matching EBITDA | Enterprise value = selected multiple × target EBITDA |
| P/E | Common equity value ÷ earnings attributable to common shareholders | Common equity value = selected multiple × target common earnings |
P/E can also use share price divided by matching earnings per share. Keep share counts, share classes, and dilution treatment consistent. EV/EBITDA starts before financing interest, while P/E uses earnings after financing and tax effects. Do not subtract debt again from a common-equity estimate already produced by P/E.
Select peers based on economics
A shared industry label is only a starting point. Compare products, customers, geography, growth, profitability, business maturity, recurring revenue, capital intensity, working-capital needs, and risk. Size and access to capital can also matter. Document why each peer belongs in the group and why any apparent outlier is retained or excluded.
For private companies, public-company trading multiples are reference evidence, not automatic answers. Ownership rights, marketability, governance, concentration, scale, and available information may differ. Do not apply a generic discount or control premium without a supported reason. Acquisition transaction multiples can also reflect control, synergies, and deal terms that trading multiples do not.
Worked example: calculate peer EV/EBITDA
Suppose three invented peers have the following values at one hypothetical valuation date. All EBITDA figures cover the same trailing twelve months, use the same definition, and are positive. Enterprise values use a consistent cash, debt, and lease convention. Assume the peers are sufficiently similar for this arithmetic illustration; real-world selection would require further evidence.
| Hypothetical peer | Enterprise value | Trailing EBITDA | EV/EBITDA |
|---|---|---|---|
| Peer A | $3,000,000 | $500,000 | 6.0× |
| Peer B | $5,600,000 | $800,000 | 7.0× |
| Peer C | $8,000,000 | $1,000,000 | 8.0× |
The median is 7.0×. A median summarizes the sample but does not prove that the target deserves that multiple. First explain how the target differs and whether the selected range is justified.
Apply the range to the target
Use target annual EBITDA of $115,000 from our EBITDA worked example. Assume current debt value of $200,000 and excess cash of $50,000, with no other bridge adjustments.
| Selected EV/EBITDA | Implied enterprise value | Less debt | Add excess cash | Implied equity value |
|---|---|---|---|---|
| 6.0× | $690,000 | −$200,000 | +$50,000 | $540,000 |
| 7.0× | $805,000 | −$200,000 | +$50,000 | $655,000 |
| 8.0× | $920,000 | −$200,000 | +$50,000 | $770,000 |
The median calculation is $115,000 × 7 = $805,000 EV. The equity bridge gives $805,000 − $200,000 + $50,000 = $655,000. This range reflects the selected multiple assumptions, not a statistical confidence interval or a promised sale price.
A separate P/E cross-check
Assume a separately supported hypothetical peer analysis suggests P/E of 12×, and the target earns $60,000 attributable to common shareholders with no preferred claims. Implied common equity value is 12 × $60,000 = $720,000.
Do not subtract the $200,000 debt again: P/E already produces equity value. This simplified P/E application treats the target’s total common earnings consistently with the peer measure; a more detailed analysis may separate nonoperating assets and their associated earnings.
The $720,000 P/E estimate differs from the $655,000 EV/EBITDA median estimate. Financing, taxes, depreciation, earnings quality, and different peer selections can explain a difference. Investigate those drivers rather than mechanically averaging the estimates to create a seemingly precise answer.
Trailing and forward multiples must match
A trailing multiple uses historical earnings, typically the latest twelve months. A forward multiple uses a specified forecast period. If a selected 7× multiple is based on next-year EBITDA, apply it to the target’s consistently defined next-year EBITDA, not the trailing $115,000 by default.
For example, 7× hypothetical next-year EBITDA of $130,000 produces $910,000 EV before the equity bridge. That different answer depends on the forecast, not merely a change of label. Align valuation dates, fiscal periods, seasonality, and reporting currency across the peer set.
Normalize carefully
Reconcile adjustments to reported earnings and consider both unusual costs and gains. A proposed owner-compensation adjustment should reflect the cost of replacement work rather than assuming the work disappears. Costs repeatedly labeled “one-time” may remain part of the business’s economics. Use the same definition for target and peer metrics.
Compare lease treatment, acquisition accounting, stock compensation, and other material differences. Reported adjusted EBITDA from two companies may exclude different items. A multiple based on one definition cannot be transferred blindly to another.
Common mistakes
- Mixing enterprise value with a common-equity denominator.
- Applying forward multiples to trailing earnings without explanation.
- Using stale prices with later financial data unavailable on the valuation date.
- Choosing peers solely because they produce a desired result.
- Assuming a low multiple proves undervaluation.
- Ignoring capital spending and working-capital needs because EBITDA excludes them.
- Subtracting debt twice or adding cash whose earnings remain inconsistently treated.
Frequently asked questions
What if earnings or EBITDA are negative?
A negative or near-zero denominator can make a multiple uninformative or unstable. Consider a suitable alternative and explain its limitations. An EV/revenue comparison still requires analysis of margins, growth, and the path to cash generation.
Are comparables better than DCF?
They answer the valuation question through different evidence. Market multiples reflect peer pricing; DCF makes forecast and discount-rate assumptions explicit. Use differences to investigate assumptions rather than choosing whichever result you prefer.
