Valuation Multiples Practice Questions

The best answers to valuation multiples questions don't just define EV/EBITDA or P/E; they explain why one company deserves a premium or discount to a peer trading at a different multiple, and interviewers use follow-up questions specifically to separate candidates who memorized definitions from those who understand what a multiple actually prices. This page is the practice set. For comp selection itself, read comparable company analysis; here you'll drill ten fresh prompts plus three local reps.

TL;DR

• EV/EBITDA is the dominant multiple in banking because it's capital-structure neutral.
• The Premium-Justify Method explains a multiple gap with growth, margin, and risk, never just "the market likes it."
• LTM multiples use trailing data; NTM multiples use forward estimates and are usually preferred.
• Ten prompts below cover multiple selection, premiums, and comp-set construction.
• The local pack checks the reasoning behind multiple gaps, not just the formulas.

What is the Premium-Justify Method?

The Premium-Justify Method forces you to name the specific driver behind any multiple difference between two companies, instead of describing the gap without explaining it.

1. State the multiples for both companies and the size of the gap.
2. Check growth first. Faster, more durable growth usually justifies a higher multiple.
3. Check margin and cash conversion. Higher-margin, more cash-generative businesses usually trade richer.
4. Check risk and concentration. Customer concentration, cyclicality, and competitive threats justify a discount.
5. Only then mention market sentiment, and treat it as the residual, not the primary explanation.

Worked example: explaining a multiple gap

Prompt: Company A trades at 12x EV/EBITDA with 15% revenue growth and a 30% EBITDA margin. Company B trades at 8x EV/EBITDA with 5% revenue growth and a 22% EBITDA margin. Both operate in the same industry. Explain the gap.

Company A's revenue growth of 15% is three times Company B's 5%, and its EBITDA margin of 30% is meaningfully higher than Company B's 22%. Both facts point toward a higher multiple for Company A, since faster growth compounds enterprise value further into the future, and a higher margin means more of each incremental revenue dollar converts to cash.

$$\frac{12\text{x}}{8\text{x}}=1.5\text{x}, \quad \text{a 50\% premium}$$

A 50% premium is large but explainable: Company A is growing three times faster and converting revenue to EBITDA at a meaningfully higher rate. If the interviewer adds that Company A also has 60% of revenue concentrated in a single customer, that risk factor should pull the justified premium down from the full 50%, even though growth and margin alone would support it.

Question 1 of 3

Two companies have similar revenue but trade at different EV/EBITDA multiples. What explains the gap?

The pack above checks multiple-gap reasoning, EV/EBITDA versus P/E logic, and LTM versus NTM selection as three separate reps.

Ten more valuation multiples prompts to practice

1. Why is EV/EBITDA preferred over EV/Revenue for a profitable, mature company? EV/EBITDA reflects actual profitability and operating efficiency, while EV/Revenue ignores margin differences entirely; for a mature, profitable company, margin differences are usually the more important driver of value.
2. When would you use EV/Revenue instead of EV/EBITDA? For high-growth or pre-profit companies where EBITDA is negative or not yet meaningful, EV/Revenue is a more usable, if cruder, comparison point.
3. Why can't you compare P/E ratios across two companies with very different capital structures? P/E is affected by leverage, since more debt means more interest expense and lower net income relative to a similar operating profile; EV/EBITDA sits above the capital structure and avoids this distortion.
4. A target company trades at a discount to its closest peer. What are three possible explanations? Lower growth, a customer concentration or governance concern, or simply a smaller size and lower trading liquidity that investors discount for; name the specific factor rather than defaulting to "the market is wrong."
5. Why do precedent transaction multiples usually run higher than trading comps multiples? Precedent transactions include a control premium, since an acquirer is paying to gain control of the company, while trading comps reflect minority, non-control stakes at the current market price.
6. What's wrong with comparing a company's multiple to the broad market average instead of a peer set? The broad market blends businesses with very different growth, margin, and risk profiles; a relevant peer set should match industry, business model, size, and growth stage as closely as possible.
7. A company just completed a stock split. Does its P/E ratio change? No, a stock split changes the share price and share count proportionally, leaving EPS and P/E unchanged; only the per-share numbers look different, not the underlying valuation.
8. Why might two companies with identical EV/EBITDA multiples still deserve different valuations in a football field? A football field triangulates across multiple methods (comps, precedent transactions, DCF), so even matching EV/EBITDA multiples can sit within different overall ranges once other methods are layered in.
9. What's a forward P/E, and why might it differ meaningfully from a trailing P/E? Forward P/E uses projected next-twelve-months earnings instead of trailing reported earnings; it can differ significantly if earnings are expected to grow or decline sharply, which trailing P/E can't capture.
10. An interviewer asks you to defend using NTM multiples over LTM multiples for a cyclical company. What do you say?** NTM multiples price where the company is heading, which matters more for a cyclical business where trailing results may reflect a peak or trough that isn't representative of normalized performance.
11. A company reports a large one-time gain from selling a division, inflating trailing EBITDA. How does that affect its multiple? Reported LTM EBITDA is overstated relative to normalized operating performance, so the trailing multiple looks artificially cheap; adjust EBITDA to exclude the one-time gain before comparing it to peers.
12. Two peers have identical multiples but very different balance-sheet leverage. Does that matter for the comparison? EV/EBITDA itself is capital-structure neutral, but higher leverage adds financial risk that isn't captured in the multiple alone, so it's worth flagging separately when presenting the comparison.

When a multiple points at EV, the EV/EBITDA and valuation multiples guide explains which numerator each denominator needs.

Common multiples and what they price

Frequently Asked Questions

Why is EV/EBITDA the dominant multiple in banking?

Because it's capital-structure neutral and reflects operating performance before non-cash charges, making it usable across companies with different debt levels and depreciation policies, unlike P/E.

What's the difference between LTM and NTM multiples?

LTM (last twelve months) uses trailing, reported financials; NTM (next twelve months) uses forward estimates. NTM is generally preferred because investors are paying for future performance, though it depends on projection quality.

How many comps should a peer set typically include?

Enough to be statistically meaningful while staying genuinely comparable, commonly somewhere in the high single digits to low double digits, prioritizing business-model and growth-stage similarity over simply maximizing the count.

Why do control premiums show up in precedent transactions but not trading comps?

Because a buyer in an M&A transaction is paying for the ability to control the company's strategy and cash flows, while a public market trade is a minority stake at the prevailing market price, with no control rights attached.

Can a multiple be misleading on its own?

Yes. A multiple only makes sense relative to a peer set and the specific growth, margin, and risk profile behind it; quoting a multiple without that context doesn't tell you whether a company is cheap or expensive.

How does this connect to a DCF?

Multiples and a DCF are usually triangulated together in a valuation range, since a DCF captures intrinsic, model-driven value while multiples capture what the market is actually paying for comparable businesses right now.

Do private companies get valued with the same multiples?

Yes, though there's no public trading multiple to observe directly. Bankers typically derive an implied multiple from a recent financing round or transaction, or apply a discount to a public comp set to reflect the illiquidity of a private stake.
