Comparable company analysis values a business using the trading multiples of similar publicly listed companies. According to the CFA Institute equity valuation curriculum, market-based methods like comps serve both as primary valuation tools and as cross-checks against intrinsic value from DCF analysis — the standard practice in every investment banking fairness opinion.
TL;DR
Comparable company analysis benchmarks a target company against the trading multiples — EV/EBITDA, EV/Revenue, P/E — of 6–12 similar publicly traded peers. EV/EBITDA is the most widely used multiple in M&A and equity research because it is capital-structure neutral and applicable across most industries. A rigorous comps analysis requires careful peer selection by industry, size, geography, and growth profile — plus EBITDA normalisation for one-time items. The output is an implied value range, not a single number. According to Liu, Nissim & Thomas (2002), forward EBITDA-based multiples consistently outperform trailing P/E in explaining cross-sectional stock valuations.

What Is Comparable Company Analysis?
Comparable company analysis is a relative business valuation method that values a company by reference to the market multiples of its publicly traded peers. Rather than building a bottom-up cash flow forecast, the analyst observes what the market is paying for similar companies today and applies those multiples to the target company’s own financial metrics.
The key multiples used in comparable company analysis:
| Multiple | Formula | Best Used For |
|---|---|---|
| EV/EBITDA | Enterprise Value ÷ EBITDA | Most industries; capital-structure neutral; the most widely used M&A multiple |
| EV/EBIT | Enterprise Value ÷ EBIT | Capital-intensive businesses where D&A is meaningful |
| EV/Revenue | Enterprise Value ÷ Revenue | Pre-profit companies; SaaS and growth businesses |
| P/E | Share Price ÷ EPS | Banks, insurance companies, mature dividend payers |
| P/B (Price-to-Book) | Share Price ÷ Book Value per Share | Financial institutions; asset-heavy businesses |
EV-based multiples (EV/EBITDA, EV/EBIT, EV/Revenue) are preferred in most contexts because they are capital-structure neutral — they value the whole business, not just equity. For a detailed explanation of the enterprise value concept, see the enterprise value vs equity value guide.
According to the CFA Institute equity valuation curriculum, market-based methods like comparable company analysis are used both as primary valuation tools and as cross-checks against intrinsic value estimates from DCF analysis.
When to Use Comparable Company Analysis
Comps work best when:
- A meaningful peer group of publicly traded companies exists in the same industry
- You need a quick, market-grounded valuation benchmark
- You are advising on M&A, IPO pricing, or secondary offerings
- You want to cross-check a DCF intrinsic value against market reality
- The company is currently profitable with observable EBITDA or EBIT
Comps are less reliable when:
- No true public market comparables exist (unique business models, private-market niches)
- The company is pre-revenue or pre-profit and EV/EBITDA multiples are not applicable
- Peer companies are themselves mispriced (comps reflect market sentiment, not intrinsic value)
- The transaction requires reflecting a control premium — use precedent transaction analysis instead
Most professional valuation analyses use comps alongside a DCF model to triangulate a value range. Comps provide the market anchor; DCF provides the fundamentals-based estimate. The business valuation guide covers how investment banks typically present both methods together in a football field chart.

How to Run a Comparable Company Analysis: Step-by-Step
A rigorous comparable company analysis follows five steps. Each requires careful judgment — the quality of the peer group and the financial normalisation are more important than the calculation itself.
Step 1: Define the Peer Group
Select 6–12 publicly traded companies that share the same industry, business model, and scale as the target. The peer group should be similar on the metrics that drive valuation — growth rate, profitability margin, capital intensity, and competitive positioning.
Common peer selection criteria:
- Industry: Primary SIC or GICS sector classification. Avoid cross-sector peers unless the business model overlap is genuine.
- Size: Market cap within 0.5×–2.0× of the target. Vastly larger or smaller companies trade at different multiples due to liquidity and scale premiums.
- Geography: Prefer same-market peers where possible; cross-border comps require adjusting for country risk and regulatory differences.
- Growth profile: High-growth peers trade at premiums to slower-growth peers. Mixing them in the same peer group without adjustment distorts the median.
Damodaran publishes EV/EBITDA multiples by industry sector annually — a useful starting point for identifying what the sector typically trades at before building a specific peer group.
Step 2: Gather Financial Data (LTM + Forward Estimates)
For each peer, collect:
- LTM (Last Twelve Months): Revenue, EBITDA, EBIT, and net income from the most recent four quarters. This is the trailing period and is always included.
- Forward estimates (NTM, +1 year, +2 year): Consensus analyst estimates for the next 1–2 years. These are essential for high-growth companies where trailing metrics understate earning power.
- Market data: Current market capitalisation and net debt to calculate enterprise value.
Primary data sources: SEC EDGAR for public filings; Bloomberg, CapitalIQ, or Refinitiv for pre-calculated financial data and consensus estimates. For individual company analysis without a data terminal, SEC EDGAR provides complete 10-K and 10-Q filings.
Step 3: Normalise for Non-Recurring Items
Raw reported EBITDA often includes one-time items — restructuring charges, litigation settlements, asset write-downs, or non-cash compensation — that do not reflect ongoing earning power. Always calculate adjusted EBITDA by stripping these out. Failing to normalise means you are comparing apples to oranges across the peer group.
Common adjustments:
- Add back: restructuring charges, impairment charges, legal settlements, M&A transaction costs
- Strip out: one-time gains, insurance proceeds, asset sale gains
- Adjust for: lease accounting differences (IFRS vs GAAP), pension treatment, stock-based compensation policy
Step 4: Calculate Trading Multiples
For each peer, calculate the key multiples. The most common in investment banking:
Enterprise Value (EV) = Market Capitalisation + Net Debt + Minority Interest + Preferred Equity
EV/LTM EBITDA = EV ÷ last twelve months adjusted EBITDA
EV/NTM EBITDA = EV ÷ next twelve months consensus EBITDA estimate
EV/Revenue = EV ÷ LTM revenue (for pre-profit or SaaS companies)
Build a summary table showing each peer’s multiples, then calculate the 25th percentile, median, mean, and 75th percentile across the peer group. The range matters as much as the median.
Step 5: Apply Multiples to the Target and Derive Implied Value
Apply the peer group median (and 25th/75th percentile) to the target company’s financial metrics to derive an implied enterprise value range. Convert to equity value by subtracting net debt.
Example: If peer group median EV/EBITDA = 9.5× and the target’s LTM EBITDA = $100M, implied EV = $950M. If net debt = $150M, implied equity value = $800M. Divide by diluted shares outstanding to get implied equity value per share.
Always present the full range — not just the median. The dispersion in peer multiples contains important information about how the market distinguishes quality within the sector.

Comparable Company Analysis in Practice
When Goldman Sachs and JPMorgan advised on the Twitter acquisition in 2022, comparable company analysis was one of three valuation methods included in their fairness opinions. Our Twitter valuation case study shows how the banks assembled peer groups from social media and digital advertising companies to benchmark Twitter’s implied multiples. The Goldman Sachs Twitter valuation analysis shows specifically how these multiples were presented alongside DCF and precedent transaction analysis in the football field chart.
A well-run comparable company analysis answers: “Given what the market is paying for similar businesses, where should this company trade?” The DCF then answers: “Given what this specific company can generate in cash flows, what is it intrinsically worth?” Where the two converge is where a defensible price lives.
Dr. Andrew Stotz, CFA — Former #1 Ranked Equity Analyst
“In equity research, the comps mistake I correct most often in junior analyst work is comparing raw reported EBITDA across the peer group. Restructuring charges, stock-based compensation, impairments, and lease accounting differences all distort it. Before you calculate a single multiple, build an adjusted EBITDA bridge for every peer. The peer group median is only meaningful if every input behind it sits on the same accounting basis.”
The 7 Most Common Comparable Company Analysis Mistakes
These errors are identified from real investment banking practice and professional equity research:
1. Using Too Large or Too Diverse a Peer Group
Including 20 peers from three different industries to get a higher median multiple is not analysis — it is reverse-engineering. A peer group of 6–10 genuinely comparable companies is more defensible than a large, diluted group. Quality of comparability matters more than quantity.
2. Failing to Normalise Financial Data
Comparing raw reported EBITDA across companies with different accounting treatments, restructuring histories, or non-cash charges produces noise, not signal. Always adjust to a consistent definition of EBITDA before calculating multiples. This step is where most first-year analysts make mistakes.
3. Using Trailing Multiples for High-Growth Companies
For companies growing EBITDA 30%+ annually, trailing (LTM) multiples make the stock look expensive when it is not. Always include NTM (next twelve months) or +1 year forward estimates for growth companies. The market prices forward earnings — your analysis should too.
4. Ignoring Capital Structure Differences in Equity Multiples
P/E multiples are affected by leverage — a highly leveraged company has lower earnings per share (higher interest expense) than an identical unlevered business. When comparing companies with different debt levels, use EV-based multiples (EV/EBITDA, EV/EBIT) that eliminate capital structure distortion.
5. Cherry-Picking Peers to Justify a Conclusion
Selecting only the highest-multiple peers to justify a high price, or only the lowest-multiple peers to justify a cheap acquisition, is a common but intellectually dishonest approach. A rigorous analysis defines peer selection criteria before running the numbers and sticks to them.
6. Presenting the Median Without Analysing the Dispersion
A peer group with an 8× median EV/EBITDA and a 4×–15× range tells a very different story than one with an 8× median and a 7×–9× range. Tight dispersion means the multiple is reliable; wide dispersion means the peer group is heterogeneous and the median is less meaningful. Always report the range.
7. Confusing Trading Multiples with Transaction Multiples
Trading comps reflect the price for a minority stake in a public company. Precedent transactions reflect prices paid to acquire full control — which typically includes a 20–40% premium. Applying trading multiples to price an acquisition undervalues the target; applying transaction multiples to value a minority position overvalues it. Use the right method for the right context. See the precedent transaction analysis guide for how deal multiples differ from trading multiples.
Comparable Company Analysis vs. Other Valuation Methods
| Method | Approach | Best For | Limitation |
|---|---|---|---|
| Comparable Company Analysis | Benchmarks against peer trading multiples | Market-grounded relative valuation; IPO pricing; M&A sanity check | Assumes peer companies are correctly valued; no intrinsic anchor |
| Precedent Transactions | Values based on past M&A deal multiples | M&A pricing; acquisition context with control premium | Historical deals may not reflect current market conditions |
| DCF (Discounted Cash Flow) | Discounts projected free cash flows | Companies with predictable cash flows; intrinsic value anchor | Sensitive to assumptions; requires detailed financial modelling |
| Dividend Discount Model | Discounts future dividends to present value | Mature dividend-paying companies | Useless for non-dividend payers |
| Asset-Based Valuation | Values net assets on the balance sheet | Holding companies, real estate, liquidation | Ignores earnings and growth capacity |
Investment banks present comparable company analysis alongside DCF and precedent transaction analysis in a “football field” chart that shows the value range from each method side by side. For a detailed explanation of how these methods are used together, see the business valuation guide.

Frequently Asked Questions: Comparable Company Analysis
What is comparable company analysis?
Comparable company analysis values a business by benchmarking it against the trading multiples of similar publicly listed companies. The most common multiples are EV/EBITDA, EV/Revenue, and P/E. The method answers the question: given what the market is paying for similar businesses, what should this company be worth? It is a relative valuation method, not an intrinsic one.
What is the most important multiple in comparable company analysis?
EV/EBITDA is the most widely used multiple in investment banking and M&A because it is capital-structure neutral (it values the whole enterprise, not just equity), it eliminates accounting differences in depreciation between companies, and it is applicable across most industries. EV/Revenue is used for pre-profit companies. P/E is used for financial institutions and mature dividend payers.
How many peers should be in a comparable company analysis?
Six to twelve peers is the standard for a professional analysis. Too few provides insufficient data to establish a reliable range. Too many, and you are including companies that are not truly comparable, which inflates or deflates the median without adding analytical value. Quality of comparability is more important than quantity.
What is the difference between comparable company analysis and precedent transactions?
Comparable company analysis reflects what the public market pays for minority stakes in similar companies today. Precedent transaction analysis reflects what acquirers paid to take control of entire companies in past M&A deals — including a control premium typically 20–40% above the pre-deal trading price. Use comps for market-based benchmarking; use precedent transactions when pricing an acquisition.
Why are EV-based multiples preferred over equity multiples?
EV-based multiples (EV/EBITDA, EV/EBIT, EV/Revenue) value the whole business independent of capital structure, making comparisons across companies with different debt levels meaningful. Equity multiples like P/E are distorted by leverage — a company with more debt has lower earnings per share, making it look more expensive on P/E even if it generates the same operating profit. EV multiples eliminate this distortion.
Can you use comparable company analysis for private companies?
Yes. Apply public market trading multiples to the private company’s financials to derive an implied enterprise value. Analysts typically apply a private company discount (10–20%) to the result to reflect lower liquidity and the lack of a public market. The discount varies based on company size, industry, and the specific purpose of the valuation (M&A vs. minority stake vs. tax purposes).
