    How Do You Value a Company? (3 Methods)

    Three methods: (1) Comparable Companies — value off public peers' trading multiples; (2) Precedent Transactions — value off multiples paid in past M&A deals; (3) DCF — value off the present value of projected free cash flows. Comps and precedents are relative/market-based; DCF is intrinsic. You triangulate all three on a football field rather than relying on one.

    Definition

    This is the single most common technical question in IB interviews, and the interviewer is testing whether you can frame valuation cleanly under three buckets and explain the tradeoffs. The headline answer: there are three primary methodologies — Comparable Companies Analysis ("comps"), Precedent Transactions, and the Discounted Cash Flow (DCF) — plus secondary methods like LBO analysis. The first two are 'relative' (market-based) and the DCF is 'intrinsic' (cash-flow based).

    Method 1: Comparable Companies Analysis ("Comps")

    You pick a set of publicly traded companies similar in industry, size, growth, and margins to the target, then apply their trading multiples (most often EV/EBITDA, EV/Revenue, or P/E) to the target's metrics. It reflects how the public market values comparable businesses today. Pros: based on real, current market data and easy to defend. Cons: no two companies are truly identical, multiples swing with market sentiment, and it gives a 'where it trades' value, not a 'what someone would pay' value. See comparable companies analysis.

    Method 2: Precedent Transactions

    Same logic as comps, but the multiples come from actual M&A transactions for similar companies rather than current trading levels. Because acquirers pay a control premium and often expect synergies, precedent transaction multiples — and therefore the implied values — are usually higher than trading comps. Pros: reflects what a real buyer actually paid. Cons: data is stale (deals happened in different market conditions), premiums are distorted by deal-specific dynamics, and disclosure is often limited. See precedent transactions.

    Method 3: Discounted Cash Flow (DCF)

    The only intrinsic method: you project the company's unlevered free cash flow over 5-10 years, discount it back to the present at the WACC, add a terminal value (via Gordon Growth or exit multiple), and sum to get enterprise value. Pros: independent of market noise, based on the company's own fundamentals, and lets you flex assumptions. Cons: extremely sensitive to inputs — small changes in WACC or terminal growth swing the value massively, so it's often called 'garbage in, garbage out.' See walk me through a DCF.

    How they compare and how you present them

    You never rely on one method — you triangulate. The standard output is a football field chart showing a value range from each method. Ranking by value (general rule): precedent transactions tend to be highest (control premium + synergies), DCF can be highest or lowest depending on assumptions, and trading comps are usually a floor. Be ready for the follow-up: 'Which gives the highest value and why?' and 'Which do you trust most?'

    Secondary / situational methods

    Mention these to show depth: LBO analysis (what a PE sponsor could pay to hit a target return — often sets a valuation floor), liquidation value (asset-based, for distressed names), sum-of-the-parts (for conglomerates valued segment by segment), and dividend discount model (for banks/financials where FCF is hard to define). Naming one or two unprompted signals you understand context-dependent valuation.

    Worked Example — With Real Numbers

    Strong delivery: "There are three main ways. First, comparable companies — I'd find public peers and apply their EV/EBITDA multiples to the target's EBITDA. Second, precedent transactions — same idea but using multiples from past M&A deals, which run higher because buyers pay a control premium. Third, the DCF — I'd project unlevered free cash flow, discount it at WACC, add a terminal value, and that gives me an intrinsic enterprise value. In practice you'd run all three and lay them out on a football field rather than trust any single one. There are also situational methods like LBO analysis, which often sets a floor, and liquidation value for distressed companies."

    Key Takeaways

    1

    Three core methods: comparable companies, precedent transactions, and DCF

    2

    Comps and precedents are relative/market-based; DCF is intrinsic/cash-flow-based

    3

    Precedent transactions usually give the highest value due to control premiums and synergies; trading comps are typically a floor

    4

    You triangulate all three on a football field — never rely on one

    5

    Naming secondary methods (LBO, liquidation, SOTP) signals depth

    Common Mistakes in Interviews

    Forgetting to label comps/precedents as relative and DCF as intrinsic — the interviewer wants that framework

    Saying precedent transactions are lower than comps — they're typically higher due to control premiums

    Diving into DCF formula detail before establishing the three-method structure

    Claiming the DCF is the 'most accurate' — it's the most theoretically sound but the most assumption-sensitive

    Confusing equity value and enterprise value when describing what each method produces

    How Interviewers Test This

    Lead with the clean three-bucket structure before any detail — interviewers grade structure first. Then label which are relative vs. intrinsic. Don't dive into DCF mechanics unless asked; have them ready as the follow-up. Always close with 'you'd use a range across all three,' which shows judgment, not just memorization.
