How do you value a company in investment banking?

Q: What are the three main valuation methodologies used in investment banking?

The three core methods are Discounted Cash Flow (DCF) which calculates intrinsic value from projected future cash flows, Trading Comparables (comps) which benchmark against how similar public companies are currently valued, and Precedent Transactions which reference what acquirers have actually paid for comparable companies. Each provides a different perspective and together they produce a valuation range.

Q: Why does valuation produce a range instead of a single number?

Valuation produces a range because each methodology captures different information. DCF reflects fundamental cash flow assumptions, comps reflect current market sentiment, and precedent transactions include control premiums. These methods rarely converge on one number. The spread between them reveals where the market disagrees with fundamentals, where control premiums exist, and where your assumptions might be wrong.

Q: What is the difference between trading comps and precedent transactions?

Trading comps value a company based on how the market currently prices similar public companies. Precedent transactions value it based on prices paid in actual M&A deals, reflecting what acquirers paid for control. Precedent multiples are typically higher because they include a control premium, usually 20-40% above the trading price.

Q: When would you rely on DCF over comparable company analysis?

DCF carries more weight for stable, cash-generating businesses with predictable cash flows where you can build reliable projections. It is the anchor to fundamental value. Comps are preferred when the company has close public peers and you need a market-based sanity check. For pre-revenue startups with no cash flows to project, DCF is impractical and only comps or precedent transactions apply.

"Price is what you pay. Value is what you get." (Warren Buffett)

Concept

Valuation is the process of determining what an asset is worth today, based on its expected future cash flows, comparable market prices, or what buyers have paid for similar assets. There is no single "correct" value. Valuation produces a range, not a point estimate. The goal is to triangulate a defensible range using multiple methodologies, then understand why they differ.

Intuition

Valuation exists because buyers and sellers need a common framework to agree on price. DCF tells you what the asset should be worth based on fundamentals, your anchor to reality. Trading comps tell you what the market will pay today, useful for checking if you're wildly off. Precedent transactions tell you what acquirers have actually paid for control, the closest proxy to a real deal. The spread between these methods reveals where the market disagrees with fundamentals, where control premiums exist, and where your assumptions might be wrong.

Components

Why do different methodologies exist?

What it is

Each valuation methodology answers a slightly different question. Intrinsic valuation (DCF) asks what the asset is worth based on its own cash flows. Relative valuation (comps) asks what the market is paying for similar assets right now.

The logic

No single method is universally correct. Markets can be irrational, making comps misleading. Forecasts can be wrong, making DCF unreliable. Using multiple methods creates triangulation. If three independent approaches point to $40-50, you have conviction. If they range from $30-70, you have a problem.

Key consideration

The "right" method depends on context. For a stable, cash-generating business, DCF carries weight. For a pre-revenue startup with no cash flows, only comps and precedent transactions apply.

What does DCF tell you?

What it is

Discounted Cash Flow (DCF) calculates intrinsic value by projecting future free cash flows and discounting them to present value using WACC.

\text{Enterprise Value} = \sum_{t=1}^{n} \frac{\text{FCF}_t}{(1 + \text{WACC})^t} + \frac{\text{[Terminal Value](/resources/terminal-value)}}{(1 + \text{WACC})^n}

The logic

A dollar today is worth more than a dollar tomorrow. DCF captures this by discounting future cash flows at a rate reflecting the risk of those cash flows. The terminal value accounts for cash flows beyond the explicit forecast period, typically 60-80% of total value.

Key consideration

DCF is only as good as your assumptions. Small changes in growth rates or WACC create massive swings in value. Always run sensitivities on terminal growth, WACC, and margin assumptions.

What do trading comps tell you?

What it is

Trading comparables value a company based on how the market currently prices similar public companies. You calculate multiples (EV/EBITDA, P/E, EV/Revenue) for a peer set and apply them to your target.

The logic

If comparable companies trade at 8x EBITDA and your target has $100M EBITDA, the implied EV is $800M. The assumption: the market has already priced in growth, risk, and margins for similar businesses.

Think about how a house gets priced. No one forecasts its future cash flows or prices out the materials. You look at the neighborhood, you look at what other houses sold for, and you compare on a square foot basis. Comps do that to a business. It is fast, it is current, and it anchors on prices buyers have actually paid, where a forecast can bake in a lot of opinion about what happens next.

Key consideration

Peer selection is everything. A "comparable" company must match on industry, size, growth profile, margin structure, and geographic exposure. A bad comp set produces a meaningless multiple.

A multiple on its own tells you nothing. Ask whether a company trading at 12x earnings is a good deal or a ripoff and there is no answer until you know the peer set. $400 a square foot is the deal of a lifetime in Manhattan. But it is robbery in Hyde Park, Chicago. Same number, different neighborhoods, opposite verdict. Cheap and expensive are always relative.

What do precedent transactions tell you?

What it is

Precedent transactions (deal comps) value a company based on what acquirers have paid for similar companies in past M&A deals. Multiples are calculated at the transaction price, not current trading levels.

The logic

Transaction multiples include a control premium, the extra amount a buyer pays to gain control of the target. This typically ranges from 20-40% above the unaffected stock price. If recent deals closed at 10x EBITDA for similar companies, that's the market-clearing price for control.

Key consideration

Timing matters. A deal done during a bull market may reflect frothy valuations. Older transactions may not reflect current market conditions. Always note the deal date and market environment.

How do you bridge equity value and enterprise value?

What it is

The equity bridge converts between Enterprise Value (total firm value) and Equity Value (value to shareholders).

\text{Equity Value} = \text{Enterprise Value} - \text{Net [Debt](/resources/debt)} - \text{Preferred Stock} - \text{Minority Interest}

The logic

Enterprise Value belongs to all capital providers: debt holders, preferred shareholders, minority owners, and equity holders. To isolate what equity holders own, subtract claims that rank ahead of or alongside common equity.

Key consideration

This bridge is testable. Know which multiples pair with which value:

EV multiples (EV/EBITDA, EV/Revenue): Use metrics available to all capital providers (pre-interest)
Equity multiples (P/E, P/BV): Use metrics available only to equity (post-interest)

Interview script

Valuation is the process of determining what an asset is worth today, and it produces a range rather than a single number. We triangulate that range using multiple methodologies: DCF anchors us to fundamental value based on future cash flows, trading comps show what the market will pay today, and precedent transactions reveal what acquirers have actually paid for control. The spread between these methods tells us where the market disagrees with fundamentals and where control premiums exist.
