## Direct answer
**Comparable company analysis** estimates a company's value by comparing it with publicly traded peers. Analysts calculate valuation multiples such as P/E, P/B, EV/EBITDA, or EV/revenue, then ask whether the target company deserves a premium, discount, or similar multiple.
The method is useful because markets price many similar businesses at the same time. It is also easy to misuse. A company is not comparable just because it shares an industry label. Growth, margins, capital intensity, leverage, accounting policies, customer concentration, cyclicality, and business quality can all justify different multiples.
## How it works
A careful comparison starts with the peer group. Good peers have similar products, customers, geography, margins, growth drivers, balance-sheet risk, and capital needs. If the peer set is too broad, the median multiple becomes a noisy industry average rather than evidence about the target.
Next, the numbers must use the same definition. Market capitalization is not enterprise value. GAAP net income is not adjusted EBITDA. Last-twelve-month results are not the same as next-year estimates. One-time gains, restructuring charges, stock-based compensation treatment, lease accounting, and unusual tax rates can distort the denominator.
Finally, the selected multiple must match the business. Banks and insurers often require book value and capital metrics. Mature businesses may be compared with earnings or free cash flow. Early-stage companies may need revenue, gross margin, and unit economics because earnings are not yet stable.
## Example
Suppose three peers trade at 18x, 20x, and 22x forward earnings, so the median is 20x. The target company is growing revenue at 8% while the peers grow at 15%, and its operating margin is 10% versus peer margins of 18%. Applying 20x directly may overstate value.
A more disciplined note would say: “The peer median is 20x, but the target has lower growth and margins, higher leverage, and a shorter operating history. A discount to the median may be reasonable unless there is evidence that margins can converge.” The number is still a judgment, but the judgment is tied to facts.
## Risks
- **False peers:** A similar product name can hide different economics.
- **Multiple compression:** Even if company fundamentals improve, industry multiples can fall when rates rise or risk appetite weakens.
- **Accounting mismatch:** Different revenue recognition, leases, stock compensation, or one-time items can make denominators inconsistent.
- **Leverage distortion:** Equity multiples can look cheap because debt holders absorb part of the enterprise claim.
- **Forecast risk:** Forward multiples depend on estimates that may be revised.
- **Selection bias:** Choosing only expensive peers can manufacture a high target value.
## Common misconceptions
Comparable company analysis is not a shortcut to a precise fair value. It is a market-based cross-check.
A low multiple does not automatically mean cheap. It may reflect slower growth, weaker margins, higher leverage, governance risk, or declining returns on capital.
The peer median is not neutral if the peer list is biased. The list is part of the model.
