When an interviewer asks 'how do you value a company?', they expect you to know three methodologies cold: comparable company analysis (trading comps), precedent transaction analysis, and discounted cash flow (DCF). This guide covers what each method does, when to use it, and how to answer the question cleanly.
The Three Core Methodologies
1. Comparable Company Analysis (Trading Comps)
You select a group of publicly traded companies similar to your target (same industry, size, geography, growth profile) and look at the multiples the market is currently paying for them – typically EV/EBITDA, EV/Revenue, or P/E. You then apply the median or mean multiple from the peer group to your target's financials to derive an implied valuation range.
Strengths: Market-based, uses real-time data, relatively quick to perform. Good for establishing where the market currently values similar businesses.
Weaknesses: Assumes the market is pricing the comps correctly. Difficult to find truly comparable companies. Doesn't account for the target's unique growth or risk profile.
2. Precedent Transaction Analysis
Similar to comps, but instead of looking at current trading multiples, you look at multiples paid in actual M&A transactions for comparable companies. This captures the control premium – the extra amount buyers pay to acquire a controlling stake.
Strengths: Reflects real transaction prices including control premiums. Useful for estimating what an acquirer would actually pay.
Weaknesses: Transaction data may be stale (old deals in different market conditions). Harder to find directly comparable transactions. Premiums vary widely based on deal circumstances.
Precedent transactions typically yield higher valuations than trading comps because of the control premium (usually 20–40% above the pre-deal share price).
3. Discounted Cash Flow (DCF)
Values the company based on the present value of its projected future free cash flows, discounted at WACC. The only intrinsic valuation method – it values the company based on its own fundamentals rather than market comparisons.
Strengths: Independent of market sentiment. Based on the company's actual cash flow generation. Can capture unique growth or risk characteristics.
Weaknesses: Highly sensitive to assumptions (WACC, growth rate, terminal value). Garbage in, garbage out. Difficult for companies with unpredictable cash flows.
Our full DCF guide covers this in detail.
When to Use Each Method
Stable, profitable company: All three methods work well. Comps and precedents for market context, DCF for intrinsic value.
High-growth / pre-profit company: EV/Revenue comps are most useful. DCF is difficult because cash flows are hard to project. Precedents may be limited.
Distressed company: Liquidation or asset-based valuation may be more appropriate. DCF doesn't work well with negative cash flows.
Financial institution: Dividend discount model or residual income model instead of DCF. P/B and P/E multiples rather than EV/EBITDA (because EBITDA is meaningless for banks).
In practice, banks always use multiple methods and present a 'football field' chart showing the valuation range from each approach side by side. The overlap gives the most defensible valuation range.
How to Answer 'Walk Me Through a Valuation'
There are three main valuation methodologies. First, comparable company analysis, where you select a peer group of similar public companies and apply their trading multiples to the target's financials to get an implied valuation. Second, precedent transaction analysis, where you look at multiples paid in recent M&A deals for comparable companies – this typically yields higher valuations because it includes a control premium. Third, the DCF, which calculates the present value of projected future free cash flows discounted at WACC. Comps and precedents give you a market-based range, while the DCF gives you an intrinsic value. In practice you'd use all three and triangulate.
Common Interview Questions
Q: Which valuation method gives the highest value? A: Usually precedent transactions (because of the control premium), then DCF (depends on assumptions), then trading comps (no premium). But this can vary significantly.
Q: If you could only use one method, which would you choose? A: Depends on context, but trading comps are the most commonly used because they're based on real market data and are quick to perform. For a thoughtful answer, say it depends on the situation and explain why.
Q: Why might comps and DCF give different answers? A: Because they measure different things. Comps reflect market sentiment and relative pricing. DCF reflects intrinsic value based on fundamentals. If the market is overvaluing a sector, comps will be high and DCF might be lower.
