Business valuation is the process of estimating the economic worth of a company, a business unit, or its equity. In M&A it underpins the price a buyer is willing to pay and the price a seller is willing to accept. Practitioners rarely rely on a single number; instead they triangulate across several methods to produce a range.
The three approaches
Valuation methods fall into three classic approaches:
Income approach
Values a business by the cash it is expected to generate, discounted for time and risk. The dominant technique is the discounted cash flow (DCF), an intrinsic method based on the firm's own forecast cash flows and risk.
Market approach
Values a business relative to what the market pays for similar companies:
- Comparable company analysis ("trading comps") — multiples of similar public companies.
- Precedent transaction analysis ("deal comps") — multiples paid in past acquisitions, which embed a control premium.
Asset (cost) approach
Values a business by its assets net of liabilities — for example book value, adjusted net asset value, or liquidation value. It is most relevant for asset-heavy, financial or distressed businesses.
The "football field"
Because each method yields a different figure, bankers summarise the results on a football field chart — a set of horizontal bars showing the valuation range implied by each method. Overlap among the bars suggests a defensible price range. Trading comps typically sit below precedent transactions (which include a control premium), with the DCF spanning a wide range depending on assumptions.
Standards of value
The "right" value depends on the standard of value being used: fair market value (a hypothetical willing buyer and seller), fair value (often used in accounting and legal contexts), and investment value (worth to a specific buyer, which may be higher because of that buyer's unique synergies).
Enterprise value versus equity value
Most M&A valuation is expressed first as enterprise value — the value of the whole operating business — and then bridged to equity value by subtracting net debt and other claims. Keeping the two straight is essential to comparing methods correctly.
