Valuation is the technical block that decides most IB interviews. The questions are predictable — comps, precedents, DCF, EV vs equity value, premium analysis — but the answers are not. Bankers are not checking whether you memorized formulas; they are checking whether you can structure a number, defend it under pressure, and switch methodology when the facts change.
This guide walks through the questions you will actually be asked, with the structured answers we drill candidates on inside Banking Prep AI.
How bankers think about valuation in interviews
A valuation in a banker's head is not a single number. It is a football field — a range of values triangulated across multiple methodologies, where each method answers a different question. Trading comps tell you what public investors pay for similar businesses today. Precedent transactions tell you what acquirers paid to take control of similar businesses recently. A DCF tells you what the cash flows are intrinsically worth at a given cost of capital. And in sponsor processes, an LBO analysis tells you the maximum a financial buyer could pay to hit their return hurdle.
When an interviewer asks 'what is this company worth?' they want the football field — not the answer from a single method. The second thing bankers test is whether you understand the assumptions behind each method. Anyone can recite that precedent transactions usually print the highest. The candidates who get the offer are the ones who can say why: control premium, synergies, market conditions at the time of the deal, and strategic rationale. The structure matters more than the multiple.
The four core valuation methodologies
Each method answers a different question. A clean interview answer names the method, the mechanic, what it includes, and what it leaves out.
Trading comps (public comparables)
Trading comps value a company against a basket of publicly-traded peers using market multiples — most commonly EV/EBITDA, EV/Revenue, and P/E. The mechanic is simple: pick a peer set that genuinely looks like the target, calculate each peer's last-twelve-months and forward-year multiples, take the median or mean, and apply the multiple to the target's metric.
The hard part is the peer set. A defensible screen filters on business model first (what they sell, to whom), then on size, geography, growth profile, margin structure and capital intensity. A common mistake is screening on industry code and calling it done. In an interview, always show your screen and bankers will immediately know you have done this work.
Trading comps reflect minority, marketable stakes. They do not include a control premium and they do not include synergies. That is why they tend to print the lowest of the four methodologies, and why it is wrong to add a control premium to comps without saying so explicitly.
Precedent transactions
Precedent transactions value a company against actual completed M&A deals in similar businesses. The mechanic mirrors trading comps: screen for relevant deals (typically the last 3–5 years), pull the announced enterprise value and the target's metrics at announcement, calculate multiples and apply them.
The structural difference: every multiple in your set already contains a control premium plus the synergies the buyer was willing to pay for. That is why precedents usually print higher than trading comps. The trade-off is staleness — a deal closed in a different rate environment, with different financing conditions, says less about today's price than a fresh trading multiple. Always disclose when your set is dominated by deals from a different cycle.
Discounted cash flow (DCF)
DCF is the intrinsic value method. You forecast unlevered free cash flow for a discrete period (typically 5–10 years), estimate a terminal value to capture everything beyond, discount each cash flow back to today at the weighted average cost of capital (WACC), and sum to enterprise value. From there, bridge to equity value by subtracting net debt and dividing by diluted shares to get price per share.
The two assumptions that matter most are WACC and the terminal value driver. For a mature company, terminal value typically explains 60–80% of total enterprise value, which means the long-term growth rate (or exit multiple) and the discount rate dominate the answer. Sensitize WACC ±100 bps and terminal growth ±50 bps and present the range — never a point estimate.
LBO analysis (as a floor in sponsor processes)
In a sale process where private equity is at the table, an LBO analysis becomes a valuation method in its own right. You back into the maximum price a sponsor could pay while still hitting their target IRR (typically 20–25%) over a 5-year hold, given a leverage assumption (commonly 5.0–6.5x EBITDA in normal markets) and an exit multiple roughly in line with entry. That maximum-price-to-still-hit-IRR becomes the price floor — strategics generally pay above that because they capture synergies a sponsor cannot.
Side-by-side: comps vs precedents vs DCF
What each method captures, what it leaves out, and where it tends to land on the football field.
| Method | What it answers | Includes control premium? | Typical position on football field |
|---|---|---|---|
| Trading comps | What public investors pay for similar businesses today | No | Lowest |
| Precedent transactions | What acquirers paid to take control recently | Yes (+ synergies) | Highest |
| DCF | Intrinsic value of the cash flows at a given WACC | Optional (acquirer view) | Middle, widest range |
| LBO analysis | Maximum a sponsor can pay to hit IRR | No (no synergies) | Floor in sponsor processes |
Enterprise value vs equity value (the trap question)
This is the single most common valuation interview trap, and the fastest way to lose credibility. Enterprise value is the value of the operating business — what a buyer pays to take over operations, regardless of how the business is financed. Equity value (also called market cap for public companies) is the residual claim on equity holders after debt and other senior claims are satisfied.
Why does it matter for multiples? EV multiples (EV/EBITDA, EV/Revenue, EV/EBIT) belong with metrics that flow to all capital providers — pre-interest, pre-financing. Equity multiples (P/E, P/B) belong with metrics that flow only to equity — net income, book value of equity. Mixing them (e.g. EV/Net Income, P/EBITDA) is structurally wrong and bankers flag it instantly.
Equity Value = EV − Debt − Preferred Stock − Minority Interest + Cash & Equivalents
DCF deep-dive: WACC, terminal value, sensitivity
When a banker says 'walk me through a DCF', they want four mechanical steps in three minutes: project unlevered free cash flow, compute terminal value, discount at WACC, and bridge to equity value. The two formulas you must own cold are unlevered FCF and Gordon Growth terminal value.
Sensitivity is non-negotiable. Always show how the answer moves when WACC and terminal growth change by realistic increments. A point estimate is a junior mistake.
FCF = EBIT × (1 − t) + D&A − CapEx − ΔNWC
TV = FCF × (1 + g) / (WACC − g)
How to structure your valuation answers like an analyst
The single biggest gap between candidates who get offers and candidates who do not is structure. The technical content is often identical. Use this template for any 'walk me through' valuation question:
- Headline the method in one sentence. 'DCF values a company as the present value of its future free cash flows discounted at the cost of capital.'
- Lay out the four or five mechanical steps in order, no more than two sentences per step.
- State the key assumptions and the sensitivity. 'Most of the value sits in the terminal — small changes in WACC or terminal growth move the answer materially.'
- Land the bridge. EV → equity value → price per share. End on a number, not a formula.
- Pause. Give the interviewer room to push.
Three minutes is the right length for a clean DCF walkthrough at summer-analyst level. Associate-level answers add nuance — mid-year convention, normalized CapEx in the terminal year, treatment of operating leases — but the structure is the same.
Common valuation interview mistakes
- Mixing levered and unlevered. Discounting unlevered FCF at cost of equity (or levered FCF at WACC) is a structural error. Cash flow type and discount rate must match.
- Treating cash and debt sloppily in the EV bridge. Forgetting to subtract cash, or to add preferred and minority interest, instantly signals you have not modeled this before.
- Quoting a single point estimate. Real valuation is a range. Anyone who answers 'the company is worth $4.7B' with no sensitivity is failing the test that the football field is built to teach.
- Adding a control premium to trading comps without saying so. Comps are minority. If you premium them up, disclose it explicitly and tie the premium to recent precedents.
- Choosing comps on industry label only. 'Software companies' is not a peer set. Match on business model, size, geography, growth, and margin structure.
- Letting terminal value dominate without sensitizing it. If 80% of your DCF value sits in the terminal, you are essentially pricing on a multiple — own that and stress-test it.
- Equating high revenue growth with high value. Growth that is funded by capex and working capital can destroy value if returns on capital are below WACC.
Worked example: framing a quick triangulation
Imagine a mid-cap industrial target with $200M of LTM EBITDA, $400M of net debt, and 50M diluted shares outstanding. A peer set of public industrials trades at a median 9.0x EV/EBITDA. Recent precedent deals in the same sub-sector closed at a median 11.0x EV/EBITDA. A quick five-year DCF at a 10% WACC and a 2.5% terminal growth rate produces an enterprise value of roughly 10.0x EBITDA-equivalent.
Trading comps imply EV ≈ $1,800M → equity value ≈ $1,400M → ~$28 per share. Precedents imply EV ≈ $2,200M → equity ≈ $1,800M → ~$36 per share. DCF lands roughly in the middle at ~$2,000M EV → ~$32 per share. The football field is $28–$36; a banker would present that range to a board, with the standalone DCF in the middle and the precedent multiple as the 'what a strategic might pay' anchor.
How to practice valuation under pressure
Reading a guide is not enough. Valuation is a verbal skill — you have to deliver a clean three-minute DCF out loud, repeatedly, until the structure is automatic and you can spend cognitive bandwidth on the interviewer's follow-ups instead of remembering the next step.
Practice in three layers: solo reps to lock the structure, peer mocks to stress-test under social pressure, and AI mock interviews for high-volume reps with instant structured feedback.
