Before there were spreadsheets, there were comps. Comparable company analysis is the oldest and most widely used valuation method on Wall Street — and it's surprisingly accessible for retail investors.
Key Takeaways
- Comps tell you what the market is willing to pay for similar businesses — not what a business is fundamentally worth
- EV/EBITDA is the most widely used multiple because it neutralizes capital structure and depreciation differences
- The quality of your comps analysis depends entirely on your peer group selection
- A low multiple doesn't always mean cheap — it may signal deteriorating fundamentals the market has already priced in
- Always cross-reference comps with DCF analysis — the two methods complement each other

What Are Comparable Company Analysis?
Comparable company analysis ("comps") values a company by comparing it to similar businesses that the market has already priced. If Peer A trades at 12x EBITDA and Peer B at 14x EBITDA, a company similar to both should reasonably trade around 13x EBITDA.
Comparable Company Analysis
A relative valuation method that estimates a company's value by comparing its financial metrics to similar publicly traded companies, using multiples like EV/Revenue, EV/EBITDA, and P/E.
Example: If similar companies trade at an average of 12x EBITDA, and your target company has $250M EBITDA, the implied enterprise value is $3.0B.
Comps are used everywhere: investment banking pitch books, equity research reports, private equity deal pricing, and even venture capital funding rounds. The method is simple, but the skill lies in choosing the right peers and interpreting what the multiples actually tell you.
Core Principle
A stock isn't cheap because it trades at $20 — it's cheap relative to what it earns, what it owns, and what similar companies trade for.
The Three Key Multiples
EV/Revenue
Enterprise value divided by total revenue. This multiple tells you how much the market values each dollar of sales.
EV/Revenue
Enterprise value divided by annual revenue. Useful for valuing companies with negative earnings or early-stage businesses where revenue growth is the primary metric.
Example: Company EV of $5B with $1B revenue = 5.0x EV/Revenue. Higher-growth companies command higher multiples.
EV/Revenue is most relevant for high-growth tech companies, SaaS businesses, and startups that aren't yet profitable. A SaaS company growing 40% annually might trade at 10x revenue, while a mature retailer grows 2% and trades at 0.5x revenue.
EV/EBITDA
The gold standard of valuation multiples. EBITDA (earnings before interest, taxes, depreciation, and amortization) approximates operating cash flow, making it comparable across companies with different capital structures.
EV/EBITDA
Enterprise value divided by EBITDA. The most widely used multiple because it strips out the effects of debt levels, tax rates, and accounting choices for depreciation.
Example: Company EV of $5B with $500M EBITDA = 10.0x EV/EBITDA. Lower is generally cheaper, but compare within the same industry.
Why EV/EBITDA beats P/E for cross-company comparison: two companies with identical operations but different debt levels will have very different P/E ratios (because interest expense reduces net income). But their EV/EBITDA will be similar because it looks at the business before financing decisions.
P/E Ratio
Share price divided by earnings per share. The most famous multiple — and the most misunderstood.
P/E Ratio
Price per share divided by earnings per share. Shows how much investors pay for each dollar of profit. Most meaningful for mature, consistently profitable companies.
Example: Stock at $100/share with $5 EPS = 20x P/E. The S&P 500 historical average is approximately 15-16x.
P/E has limitations: it's affected by one-time charges, tax rate changes, and share buybacks. A company can "improve" its P/E ratio by buying back shares (reducing the share count) without actually improving operations. Always look at P/E alongside EV/EBITDA.

Peer Multiples
| Company | EV/Revenue | EV/EBITDA | P/E | |
|---|---|---|---|---|
| Average | 4.1x | 11.9x | 21.3x |
Implied Valuations
EV/Revenue Method
$4.13B
1000M revenue × 4.1x
EV/EBITDA Method
$2.98B
250M EBITDA × 11.9x
P/E Method
$3.20B
150M net income × 21.3x
Valuations Are Consistent
Both methods converge around $3.09B, suggesting consistent market pricing for this company's fundamentals.
Worked Example: Valuing a SaaS Company
Let's walk through a realistic comps analysis for a hypothetical SaaS company:
Target Company: "CloudOps Inc."
Revenue: $1,000M
EBITDA: $250M (25% margin)
Net Income: $150M
Growth: 30% YoY
Using the peer multiples above, the average EV/EBITDA is 11.9x. Applied to CloudOps's $250M EBITDA, the implied enterprise value is $2.98B.
The EV/Revenue multiple of 4.1x implies $4.13B, and the P/E of 21.3x implies $3.20B.
Limitations and When Comps Mislead
Comps are powerful but not infallible. Understanding their limitations is just as important as knowing how to use them:
- Market inefficiency: Comps assume peers are correctly priced. During the 2021 tech bubble, SaaS companies traded at 30x+ revenue — which looked "normal" until the correction.
- No two companies are identical: Even close competitors differ in growth rates, margins, customer concentration, and competitive positioning. Adjusting for these differences is an art, not a science.
- Cyclicality: EBITDA and earnings fluctuate with economic cycles. A company may look "cheap" at the peak of a cycle (low P/E because earnings are inflated) and "expensive" at the trough.
- Accounting differences: Companies in different countries or industries may calculate EBITDA differently. Always verify the definitions.
