Valuation Methods Pros & Cons: William Blair 2027 Interview Guide
Valuation methods pros cons William Blair interviewers expect you to rattle off: DCF (intrinsic, assumption-heavy), comps (market-based, noisy), precedent transactions (control premium, scarce data). For the 2027 intake, candidates report being asked exactly this — list the methods and argue each one's strengths and weaknesses.
Valuation Methods Pros Cons: The Three Blair Expects
One — DCF: project free cash flows, discount at WACC, add terminal value. Pro: intrinsic, built on the company's own fundamentals. Con: hypersensitive to assumptions — nudge growth or WACC and the value swings wildly ("garbage in, garbage out"). Two — Trading comps: value via EV/EBITDA and P/E multiples of similar publics. Pro: market-based — what investors actually pay today. Con: no two companies are truly comparable, and markets can be irrational. Three — Precedent transactions: multiples from past M&A deals. Pro: reflects real control premiums — what acquirers actually paid. Con: scarce, stale data with unique synergies baked in. Know all three cold, because Blair asks for the list, then attacks each one.
Valuation Methods Pros Cons: How to Structure Your Answer
Answer like a banker. Open with the one-line list: "The three main methodologies are DCF, trading comps, and precedent transactions." Give each 20 seconds: what it is, biggest strength, biggest weakness. Then land the close that separates good from great: "In practice, bankers triangulate — no serious valuation uses one method. On a sell-side M&A process like Blair's, precedents and comps anchor the discussion because they reflect what buyers pay, while the DCF is the fundamental sanity check." Never call one method "the best" unqualified — the answer is "it depends," followed by a reasoned view.
Which Valuation Method Does William Blair Trust Most?
In Blair's middle-market M&A practice, precedents and comps carry the most weight — clients care what buyers actually paid for similar businesses; the DCF is the internal cross-check. Interviewers listen for deal reality versus textbook theory. Mentioning that precedents bake in control premiums — typically 20–30% over unaffected prices — signals you understand M&A, not just corporate finance. Our product covers Blair's real valuation questions, including the pros-and-cons grilling and "which method and why" follow-ups, with sample answers in how Blair bankers actually talk.
Valuation is the vocabulary of the whole technical interview — DCF, comps, and the paper LBO all assume fluency. In the 2027 intake, candidates who list three methods but defend one get exposed within two follow-ups. Learn all three, learn the weaknesses honestly, learn the triangulation close. A three-minute answer underwriting everything after it.
FAQ
What are the three main valuation methods? DCF, comparable company analysis (trading comps), and precedent transactions. Every banking interview expects this list.
What is the DCF's biggest weakness? Assumption sensitivity. Small changes in WACC, terminal growth, or projections swing the value — output is only as good as inputs.
Why use precedent transactions despite limited data? They show actual control premiums paid by real acquirers — the closest proxy for "what would someone pay," which is what matters in M&A.
Which method matters most at Blair? Market-based methods (precedents, comps) anchor client discussions in Blair's M&A practice; DCF serves as the fundamental cross-check.
