What Is Comparable Companies Analysis?
Comparable companies analysis, commonly called "comps" or "trading comps," is a relative valuation methodology that determines a company's value by examining how similar public companies are valued by the market. The underlying principle is that similar companies should trade at similar multiples of their financial metrics.
The Comps Process
The process follows a structured series of steps. First, select a universe of comparable companies. The ideal peer group shares similar industry classification, business model, size, growth profile, profitability, and geographic exposure. In practice, finding perfect comparables is rare, and analysts must exercise judgment about which similarities matter most.
Second, gather the relevant financial data for each comparable company — typically revenue, EBITDA, EBIT, net income, and key balance sheet items. This data comes from public filings (10-Ks, 10-Qs) and consensus analyst estimates for forward metrics.
Third, calculate key valuation multiples for each comparable. The most common are EV/Revenue, EV/EBITDA, EV/EBIT, P/E, and Price/Book. For specific industries, specialized multiples are used: EV/Subscribers for media, Price/FFO for REITs, or EV/Reserves for mining.
Fourth, analyze the range of multiples. Calculate the mean, median, 25th percentile, and 75th percentile. Identify outliers and understand why they may trade at premiums or discounts (faster growth, higher margins, market leadership, etc.).
Finally, apply the selected multiple range to the target company's corresponding financial metric to derive an implied valuation range.
Selecting the Right Peers
Peer selection is the most important and most subjective step. Start with companies in the same industry and sub-industry. Narrow by size (typically within 0.5x-2x of the target's revenue), growth rate, margin profile, and geographic mix. Most comps analyses use 5-15 comparable companies.
Bankers often present two peer groups: a "core" group of the most similar companies and a "broader" group that includes less direct comparables. This provides context for where the target should trade within the range.
Strengths of Comps
Comps reflect current market sentiment and actual investor expectations, making them relevant for pricing transactions. They are straightforward to calculate and easy to explain to clients. The methodology is based on real, observable data rather than subjective projections. Comps are also quick to update as market conditions change.
Limitations of Comps
No two companies are truly identical, so judgment is always required. Market-wide overvaluation or undervaluation affects all peers equally, potentially leading to mispriced targets. Comps also struggle with companies that have unique business models or no close peers. Accounting differences across companies can distort comparisons if not adjusted.
Comps in Practice
Comps are used in nearly every investment banking engagement — M&A advisory, IPOs, fairness opinions, and general advisory. In M&A, the comps range provides a floor or ceiling for negotiations. In IPOs, comps help set the initial price range. The output is typically presented as a "football field" chart showing the valuation range implied by different methodologies.
