Business and Corporate Valuation
Why an entire business is harder to value than a single security
The security valuation chapter valued equity shares, preference shares and debentures individually, each with a relatively well-defined cash flow stream. Valuing an entire business scales this same discounting logic up to a whole firm's future cash flows, but introduces genuinely harder judgement calls: estimating a growth rate and terminal value for a business as a whole, choosing an appropriate set of comparable companies when no two businesses are ever truly identical, and reconciling the fact that different, individually defensible valuation approaches routinely produce meaningfully different answers for the same company.
Discounted cash flow (DCF) approaches
Free cash flow to firm (FCFF) and free cash flow to equity (FCFE), already introduced in the security valuation chapter for valuing equity specifically, are the primary DCF tools for whole-business valuation, applied here with the added complexity of projecting a multi-year forecast for an entire operating business, not merely a dividend stream.
Building the explicit forecast. A DCF valuation typically projects revenue growth, margins, reinvestment needs (capital expenditure and working capital), and the resulting free cash flow for an explicit forecast period — commonly five to ten years, chosen to extend roughly until the business is expected to reach a stable, mature growth phase — with each year's projection built up from operational drivers (unit volume, pricing, cost structure) rather than a single top-line growth assumption applied mechanically to every line item.
Terminal value. As the multi-stage dividend discount model established in the security valuation chapter, the value of cash flows beyond the explicit forecast period is captured by a terminal value, most commonly computed using the Gordon growth (perpetuity growth) method — Terminal value = [Final year FCF × (1 + stable growth rate)] ÷ (Discount rate − Stable growth rate) — or the exit multiple method, applying an assumed multiple (such as EV/EBITDA) to the final explicit-period financial metric, based on what comparable, mature businesses currently trade at. The stable growth rate used in the Gordon growth terminal value must be conservative and defensible — a rate exceeding the long-run growth rate of the overall economy is generally considered unsustainable indefinitely, since a business growing faster than the entire economy forever would eventually become implausibly, indeed impossibly, large relative to the whole economy it operates within.
Sensitivity of terminal value. Exactly as flagged in the security valuation chapter, terminal value typically represents the substantial majority of a DCF valuation's total computed value, meaning the assumptions feeding into it — the stable growth rate and the discount rate specifically — deserve disproportionate scrutiny relative to any single year's explicit-period assumption, and a strong valuation answer explicitly tests how sensitive the final valuation conclusion is to small, plausible changes in these two terminal-value inputs specifically.
Relative valuation (multiples)
The core logic. Relative valuation values a company by comparing it to similar, comparable companies (or comparable historical transactions) using a standardised multiple — P/E (price to earnings), EV/EBITDA (enterprise value to earnings before interest, tax, depreciation and amortisation), P/BV (price to book value), or EV/Sales — under the premise that similar companies, facing similar growth and risk prospects, should trade at broadly similar multiples of a common financial metric.
Choosing the right multiple. EV/EBITDA is often preferred over P/E specifically because it is capital-structure-neutral — EBITDA is measured before interest, meaning it is unaffected by how a company happens to be financed (debt versus equity), while P/E's earnings figure sits below interest expense, meaning a highly leveraged company's earnings, and therefore its P/E ratio, is directly affected by its financing choice in a way that can distort comparability against a less-leveraged peer with otherwise identical operating performance; EV, the numerator in EV/EBITDA, correspondingly includes both debt and equity, matching the capital-structure-neutral nature of the EBITDA denominator.
Selecting comparable companies. A genuinely defensible comparable company set should match the target on industry, size, growth prospects, margin structure, and risk profile as closely as possible — a mismatch on any of these dimensions (comparing a small, high-growth technology company against large, mature technology incumbents, for instance) can produce a systematically misleading multiple-derived valuation, since the market-observed multiples of the comparable set embed the market's assessment of those companies' own specific growth and risk characteristics, not the target company's.
Precedent transaction analysis is a variant of relative valuation using multiples paid in recent, comparable M&A transactions rather than trading multiples of currently listed comparable companies, and typically produces a higher valuation than trading-comparable multiples, since observed transaction prices generally embed a control premium — the additional amount an acquirer is willing to pay to obtain outright control of a target, over and above the price at which the target's shares merely trade in the ordinary secondary market, reflecting the value of being able to direct the target's strategy, extract synergies, and access its cash flows fully rather than merely holding a minority, non-controlling stake.
Asset-based valuation
Net asset value (NAV) values a business as the fair value of its identifiable assets less its liabilities — a valuation approach that is generally considered a floor or liquidation-value reference point rather than the primary valuation method for a genuinely going-concern operating business, since it captures the value of assets on the balance sheet but typically fails to capture the value of a business's ongoing earning power, brand, customer relationships, and other intangible sources of value that a going concern's future cash flows (captured by DCF) or market-observed trading multiples (captured by relative valuation) reflect far more directly. NAV is most relevant for asset-heavy businesses whose value is genuinely closely tied to their underlying asset base (a real estate holding company, an investment company holding a portfolio of securities) or for a business genuinely being valued for liquidation rather than continued operation.
Why valuation approaches diverge, and how to reconcile them
DCF, relative valuation and NAV rest on genuinely different premises, and a competent valuation answer does not treat this divergence as an error to be resolved by simply averaging the results. DCF reflects the specific company's own projected cash flows and a chosen, company-specific discount rate, and is only as reliable as those specific projections and assumptions. Relative valuation reflects what the broader market is currently willing to pay for genuinely comparable businesses, embedding current market sentiment (which can itself be temporarily too optimistic or too pessimistic) but avoiding the need to build an independent, potentially fragile long-term cash flow forecast. NAV reflects the value of assets currently on the balance sheet, largely ignoring the business's forward-looking earning capacity entirely.
A strong valuation answer explains the divergence, not merely reports it — identifying specifically whether the DCF's growth or margin assumptions are more or less optimistic than what the comparable companies' own current multiples imply, whether the comparable set genuinely matches the target's risk and growth profile, and which approach's underlying assumptions the analyst finds most defensible given the target's specific circumstances — before arriving at a final valuation conclusion, whether a single point estimate or a supported range, exactly as the method chapter's advice on reconciling valuation approaches, rather than defending one number dogmatically, established at the start of this paper.
Why this chapter feeds directly into the next
Business valuation is not typically an end in itself in professional practice — it is almost always undertaken to inform a specific decision: whether to invest, whether to lend, or, as the next chapter takes up directly, whether and at what price to acquire the business entirely. Treat every valuation technique developed here as the direct analytical foundation the mergers and acquisitions chapter builds its own, additional decision framework on top of.
