How Do You Value a Company? (Investment Banking Interview Answer)

"How do you value a company?" is the valuation version of the three-statement walkthrough. Almost every summer analyst process asks it. Interviewers are not looking for a TED talk. They want three methods, a clear sentence on how each works, and a thoughtful take on when you trust each one. Then they will drill whichever method you seem weakest on.

The 45-second answer

"I would look at three methods. First, a DCF: project unlevered free cash flow, discount at WACC, add terminal value, get enterprise value, then bridge to equity value and share price. Second, trading comps: apply peer EV/EBITDA or P/E multiples to the target. Third, precedent transactions: use multiples from closed M&A deals, which usually include a control premium. I triangulate across all three rather than relying on one number."

That answer works in HireVue and first rounds. In a superday, expect follow-ups on each leg. Elite boutiques will push you into the details faster than a behavioral-heavy bulge bracket first round.

Method 1: DCF (intrinsic value)

Mechanics

UFCF = EBIT(1 − t) + D&A − CapEx − ΔNWC
Enterprise Value = PV of projection-period UFCFs + PV of Terminal Value
Equity Value = EV − Net Debt (+/− other adjustments)
Share Price = Equity Value ÷ Diluted Shares

Terminal value is usually:

• Exit multiple: Year N EBITDA × exit multiple, then discount
• Perpetuity growth: UFCF_(N+1) / (WACC − g), then discount

What to say about strengths and weaknesses

Strength: ties value to cash flow assumptions you can debate explicitly.
Weakness: sensitive to WACC and terminal value. Small assumption changes move value a lot.

Interview follow-ups inside the DCF

"Walk me through a DCF." Have a separate 90-second version. Do not cram the full DCF into the valuation overview.

"Why unlevered free cash flow?" It is independent of capital structure in the cash flow itself, so you discount at WACC and get enterprise value.

"What is WACC?" Blended required return on debt and equity. Cost of equity from CAPM. After-tax cost of debt because interest is deductible.

"Exit multiple vs perpetuity growth?" Exit multiple is often easier to defend with comps. Perpetuity growth should be conservative (long-run economy inflation/real growth territory). Never let g ≥ WACC.

"Stub period / mid-year convention?" Mentions can earn you senior points. Only bring them up if you can explain simply: cash flows do not all arrive on December 31.

Method 2: Trading comps (public market)

Mechanics

1. Select peers by industry, business model, size, growth, margins, geography
2. Compute multiples on LTM and forward metrics (EV/Revenue, EV/EBITDA, P/E)
3. Use median or trimmed mean (watch outliers)
4. Apply to target metrics
5. Bridge EV to equity to per-share if needed

Strengths and weaknesses

Strength: live market pricing, updateable, easy to show in a pitch book.
Weakness: no control premium, peers are imperfect, one noisy trading day moves the range, accounting differences distort LTM.

Follow-ups

"How do you pick comps?" Start with industry classification, then refine with growth, margins, customers, and size. Explain who you excluded and why.

"LTM or forward?" Show both when you can. Growth companies often trade on forward multiples. Always define the earnings base.

"EV/EBITDA vs P/E?" EV/EBITDA is capital-structure light and pairs with enterprise value. P/E is after interest and pairs with equity value. Do not mix them.

Method 3: Precedent transactions (deal market)

Mechanics

1. Select closed deals: sector, size, geography, vintage
2. Compute transaction EV / target financial metrics at announcement
3. Note premium to unaffected share price
4. Apply median multiple; cross-check implied premium

Strengths and weaknesses

Strength: shows what acquirers paid for control, including synergies baked into price.
Weakness: small samples, unique deal terms, earnouts, different rate environments, stale deals.

Why precedents often exceed trading comps

Precedent multiple ≈ trading multiple + control premium + synergy expectations

Buyers pay for 100% control and for synergies the public minority market may not fully capitalize. Saying this out loud is an easy senior signal.

When each method should lead

A football field is just these methods side by side. If midpoints are miles apart, your EBITDA definitions probably do not match, or your DCF terminal assumptions are aggressive.

Equity value vs enterprise value inside valuation answers

Say which value you are solving for before you apply a multiple.

Bridge:

Equity Value = Enterprise Value − Net Debt (+/− NCI, preferred, investments, etc.)

Getting this wrong is one of the fastest ways to lose credibility after a polished "three methods" opener.

How to talk about a valuation range

Interviewers like hearing a range, not a false precise intrinsic value to the penny.

Example shape:

"I would expect a range of $X to $Y per share. Comps center around $A, precedents around $B, and my base DCF around $C. I would weight [method] more here because [reason]."

You will not always have numbers in a conceptual interview. Still practice the sentence structure so you do not sound like valuation is a single point estimate from a textbook.

Student prep mistake

Memorizing "DCF, comps, precedents" without being able to do any of the math. If you name DCF, define UFCF. If you name comps, know EV vs equity multiples. If you name precedents, explain control premium.

Another mistake: treating banker teasers as truth. Teasers often lead with NTM multiples. Convert to LTM language so you know what is really being paid.

Practice path that converts to offers

Week 1: Verbal fluency

• Day 1: 45-second overview on camera until boring
• Day 2: 90-second DCF walkthrough + WACC
• Day 3: comps process + EV/EBITDA vs P/E
• Day 4: precedents + why multiples are higher
• Day 5: mixed mock with interruptions ("why not just use comps?")

Week 2: Build reps

• One trading comps case with a peer set you can defend
• One precedent set with at least a handful of deals
• One DCF with sensitivity on WACC and exit multiple
• Say the football field out loud from the outputs

Live graded comps and DCF cases beat reading another PDF. The interview is oral, but confidence comes from having built the backup tabs.

Connecting this to SheetRank deals

Project Atlas-style comps work trains peer selection and multiple math. Harborview-style M&A work trains how valuation feeds deal decisions. Catalyst-style three-statement and DCF work trains the intrinsic side. Use the verbal overview as the map, then earn it with builds so you are not bluffing in a superday.
