Valuation Interview Questions and Answers
Questions
1. Walk me through how you would value a company.
- Three main approaches:
1. DCF (intrinsic)
2. Comparable Company Analysis (market multiples)
3. Precedent Transactions (M&A multiples)
- Usually start with DCF as the most βtheoretical,β then cross-check with multiples.
2. Why do we use enterprise value multiples (EV/EBITDA) instead of price multiples (P/E) when valuing a company?
- EV/EBITDA is capital-structure neutral β compares companies
regardless of debt/equity mix.
- P/E is distorted by leverage, non-operating items, and tax
rates.
3. When would you use a sum-of-the-parts (SOTP) valuation?
- Conglomerates with distinct business units (e.g., GE,
Berkshire Hathaway, Alibaba).
- When a company has non-operating assets (real estate, stakes
in other companies).
4. Which is higher: EV/EBITDA or EV/EBIT? Why?
- EV/EBITDA is almost always higher because EBITDA > EBIT (adds
back D&A).
- Exception: companies with negative depreciation (rare).
DCF Questions
5. Walk me through a DCF.
- Step-by-step:
1. Project free cash flows (FCF) for 5β10 years
2. Calculate WACC (discount rate)
3. Terminal value (Gordon Growth or Exit Multiple)
4. Discount everything to present
5. Subtract net debt β Equity value
6. How do you calculate unlevered free cash flow (FCF)?
- EBIT Γ (1 β tax rate)
D&A β CapEx β ΞNWC
Other non-cash items
7. How do you calculate WACC?
o WACC = [E/(D+E)] Γ Re + [D/(D+E)] Γ Rd Γ (1 β Tc)
o Re = Rf + Ξ² Γ ERP (sometimes + size premium or country risk)
8. Why do we use mid-year convention in DCF?
- Cash flows are assumed to occur evenly throughout the year, not on the last day.
9. Terminal value: Exit multiple vs. Gordon Growth β which one do you prefer and why?
- Most PE/IB use exit multiple (more market-based).
- Gordon Growth assumes perpetual growth (often too theoretical; growth rates > GDP are unsustainable long-term).
10. If a companyβs growth rate is higher than WACC, Gordon Growth formula breaks β what do you do?
- You cannot use a growth rate > discount rate in perpetuity.
- Use a two-stage model or normalize growth to a sustainable rate
(2β4%).
Multiples & Comparable Companies
11. How do you choose comparable companies?
- Industry, size (revenue/EBITDA), growth rate, margins, geography, business model.
12. A company trades at 8x EV/EBITDA while peers trade at 12x. Is it undervalued?
- Not necessarily. Could have lower growth, lower margins, higher risk, worse management, etc.
13. Why do precedent transactions usually have higher multiples than trading comps?
- Control premium (typically 20β40%).
14. Football field valuation β what is it?
- Chart showing the range of values from different methodologies (DCF, comps, precedents, LBO, etc.).
15. Walk me through a quick LBO model.
- Entry multiple β Debt/Equity raised β Project financials β Exit at same or higher multiple β Calculate IRR/MOIC.
16. What drives returns in an LBO?
- Entry multiple (lower = better)
- De-levering (paying down debt)
- EBITDA growth
- Exit multiple expansion
17. What is a reasonable IRR for private equity?
- Typically 20β30%+ gross IRR (depends on vintage, strategy, fund size).
Brain Teasers & Quick Math
18. If a company does $100M revenue growing 10% forever, 30% EBITDA margin, WACC 10%, net debt $50M β ballpark value?
- EBITDA = $30M β Perpetual FCF β $21M (assuming CapEx = D&A)
- EV = $21M / 10% = $210M β Equity = $160M
19. If depreciation = CapEx and no change in NWC, what is FCF as % of EBITDA?
- FCF = EBIT(1-t) + Dep β CapEx β ΞNWC β EBITDA(1-t)
- So roughly 70% (assuming 30% tax rate).
20. If interest rates rise, what happens to valuation multiples?
- Multiples compress (higher discount rates β lower present value).
Bonus Hard Questions
β’ βWhich valuation method would give the highest value for a high-growth tech company vs. a mature utility?β
- Tech β DCF (captures growth); Utility β Multiples (stable cash flows).
β’ βHow would you value a biotech with no revenue but a drug in Phase III?β
- Risk-adjusted NPV (rNPV) of future cash flows from the drug.
β’ βHow does a $1 increase in depreciation affect valuation in a DCF?β
- Tax shield (+$0.40 if 40% tax), but reduces EBIT β net ~$0.40 increase in FCF.
