What Makes a Business Valuable — Cash Flows, Growth, and Risk

All of valuation reduces to three variables: the cash flows a business generates, the rate at which those cash flows grow, and the risk embedded in both. McKinsey's core finding — presented in Chapter 4 of Valuation — is that ROIC and growth together explain the overwhelming majority of differences in enterprise value across companies. Businesses that earn high returns on invested capital and grow efficiently create value. Businesses that grow but earn below their cost of capital destroy it.

What you'll learn
  • Identify the three fundamental value drivers: cash flows, growth, and risk
  • State McKinsey's key value driver formula and explain each component
  • Explain the ROIC-WACC spread as the determinant of whether growth creates or destroys value
  • Calculate how changes in each value driver affect enterprise value
  • Distinguish value-creating growth from value-destroying growth

The Three Drivers of Value — Cash Flows, Growth, Risk

McKinsey Key Value Driver Formula

EV = NOPAT × (1 − g/ROIC) / (WACC − g)

Where (1 − g/ROIC) is the free cash flow margin and (WACC − g) is the discount spread

Figure 7.1 — The value drivers triangle and KVD formula. Three identical businesses at $50M NOPAT can be worth vastly different amounts depending solely on ROIC vs. WACC spread.

McKinsey's empirical research across thousands of companies over decades produces a consistent finding: the value of any business is determined by three and only three fundamental variables. Every ratio, multiple, and model used in practice is ultimately a shorthand for estimating one or more of these three drivers. Understanding them directly — rather than through the shorthand — produces more insight per unit of analysis.

  • Cash flows: the amount of cash the business generates that can be distributed to investors after all reinvestment needed to sustain and grow the business. Free cash flow to the firm (FCFF) = NOPAT − Net Investment. Higher operating margins, lower capital intensity, and lower reinvestment requirements all increase free cash flow for a given revenue level.
  • Growth: the rate at which the business's revenue, earnings, and free cash flow expand over time. Growth is only valuable if the business earns adequate returns on the capital required to generate it. A business that grows revenue at 20% but must reinvest every dollar of earnings to do so — earning zero return on new investment — creates no additional value from growth.
  • Risk: the uncertainty around both the level and the timing of future cash flows, reflected in the discount rate. Higher risk → higher discount rate → lower present value for the same cash flows. Risk comes from operating (business) sources (competitive dynamics, pricing power, customer concentration) and financial sources (leverage, maturity structure of debt).

McKinsey's foundational empirical observation: companies that sustain high ROIC and grow create value for shareholders far exceeding those that simply grow (without ROIC discipline) or maintain ROIC (without growth). The combination is multiplicative, not additive. A business with 25% ROIC that grows at 8% is worth dramatically more than a business with 8% ROIC that also grows at 8% — even though both grow at the same rate. ROIC is the quality of growth; growth is the quantity. Value creation requires both.

McKinsey's Key Value Driver Formula — ROIC and Growth

McKinsey derives the key value driver formula from first principles by combining the DCF perpetuity approach with the economic definition of free cash flow. The result is elegant: value is a function of operating profit, ROIC, growth, and the cost of capital — with no other variables required at the enterprise level:

McKinsey Key Value Driver Formula

Enterprise Value = NOPAT × (1 − g/ROIC) / (WACC − g)

NOPAT = Net Operating Profit After Tax; g = sustainable growth rate; ROIC = Return on Invested Capital; WACC = Weighted Average Cost of Capital

ROICGrowth Rate (g)1 − g/ROICWACC − gEnterprise Value
15%5%0.6670.050$100M × 0.667/0.050 = $1,333M
15%8%0.4670.020$100M × 0.467/0.020 = $2,333M
10% (= WACC)5%0.5000.050$100M × 0.500/0.050 = $1,000M
10% (= WACC)8%0.2000.020$100M × 0.200/0.020 = $1,000M
7% (< WACC)5%0.2860.050$100M × 0.286/0.050 = $571M
7% (< WACC)8%−0.1430.020$100M × (−0.143)/0.020 = −$714M (growth destroys value!)

When ROIC = WACC (10% in the example), growth does not change enterprise value — from $1,000M at 5% growth to $1,000M at 8% growth. This is the central insight: growth only creates value when ROIC > WACC. Below WACC, growth actively destroys value — as shown in the bottom row, where aggressive growth at 8% for a business earning 7% ROIC produces a negative (mathematically: value-destroying) enterprise value implication. Many companies 'grow' into lower valuations precisely because they are investing capital at below-cost returns.

The ROIC-WACC Spread — The Only Measure That Matters for Value Creation

The ROIC-WACC spread (ROIC minus WACC) is the single most important metric in corporate finance. It tells you whether each incremental dollar invested in the business creates or destroys value for shareholders. Economic profit — the dollar version of the spread — captures this directly:

Economic Profit (EP)

Economic Profit = Invested Capital × (ROIC − WACC)

Positive EP = value creation; zero EP = breakeven; negative EP = value destruction

ROIC-WACC SpreadArchetypeReal-World ExamplesValue Creation Implication
>15% spreadDominant franchiseVisa, Mastercard, Google (Alphabet), LVMHEvery dollar of growth creates enormous value; capital is precious; protect the moat
5–15% spreadStrong competitive positionApple, Microsoft, Amazon, quality industrialsGrowth creates significant value; reinvestment is warranted; manage capital allocation carefully
0–5% spreadAverage businessMost mature industries, commoditized businessesGrowth creates modest value; prioritize capital efficiency; return excess capital to shareholders
Near zero (ROIC ≈ WACC)Value-neutralHighly competitive industries approaching equilibriumIndifferent between investing and returning capital; growth is a wash
Negative spread (ROIC < WACC)Value-destroyingAirlines (historically), telecom infrastructure, capital-intensive retailersGrowth actively destroys value; should shrink, restructure, or return capital rather than invest

Visa and Delta Air Lines both grow revenue at ~7–10% annually. Visa earns ~40% ROIC on minimal invested capital (its business is software and brand — almost no physical capital required). Delta earns ~8% ROIC on massive invested capital (planes, gates, maintenance facilities). With a WACC of roughly 9% for both: Visa's ROIC-WACC spread ≈ +31%; Delta's spread ≈ −1%. Visa's growth creates enormous value; Delta's growth at best breaks even. This explains why Visa trades at 30× earnings and Delta at 6× — not because investors arbitrarily prefer Visa, but because Visa's capital structure and competitive dynamics create far more value per dollar of growth.

The Cash Flow Identity — Why Reinvestment Reduces Near-Term FCF but Creates Long-Term Value

A common source of confusion in fundamental analysis: companies with the highest accounting earnings are not necessarily the most valuable. What matters is free cash flow — earnings after the reinvestment required to generate future growth. High-growth companies often show low or negative free cash flow precisely because they are reinvesting aggressively for future value:

  • The reinvestment rate: the fraction of NOPAT reinvested back into the business = Net Investment / NOPAT. Alternatively, the reinvestment rate = g / ROIC. A company growing at 10% with 20% ROIC reinvests 50% of earnings; a company growing at 10% with 10% ROIC reinvests 100% of earnings (all earnings go back in — zero free cash flow!); a company growing at 10% with 8% ROIC must reinvest more than all earnings — it needs external financing just to sustain growth.
  • Amazon's apparent paradox: Amazon generated near-zero free cash flow for many years while being one of the most valuable companies on earth. This is NOT a contradiction — Amazon was growing at 20–30% with ROIC well above WACC, so every dollar reinvested was creating far more than a dollar of value. The near-zero FCF reflected massive value-creating reinvestment, not operational failure. The DCF model captures this correctly because it values the future FCF that the reinvestment will eventually generate.
  • The capital light advantage: companies that require minimal capital reinvestment to grow (Visa, Microsoft, Google at maturity) convert a very high fraction of earnings into free cash flow. A business growing at 5% with 50% ROIC reinvests only 10% of earnings and distributes 90% as free cash flow. This capital efficiency — not just the earnings level — is what makes these businesses worth 30–40× earnings.
  • Sustainable growth rate: the maximum rate a business can grow without external financing = ROIC × (1 − dividend payout ratio). This is the intrinsic organic growth capacity. Companies that grow faster than their sustainable growth rate must issue equity or take on debt to fund the difference.

Reinvestment Rate Identity

Reinvestment Rate = g / ROIC

Free Cash Flow = NOPAT × (1 − Reinvestment Rate) = NOPAT × (1 − g/ROIC)

Key Takeaways

  • Three value drivers: cash flows (NOPAT), growth rate (g), and risk (WACC) — all other metrics are proxies for one of these
  • McKinsey key value driver formula: EV = NOPAT × (1 − g/ROIC) / (WACC − g) — value depends on the ROIC-WACC spread and the growth rate, not just growth alone
  • Growth only creates value when ROIC > WACC; when ROIC = WACC, growth is value-neutral; when ROIC < WACC, growth destroys value — the most important single insight in corporate finance
  • Reinvestment rate = g / ROIC — high-ROIC businesses (like Visa) can grow significantly while still generating high FCF; low-ROIC businesses must reinvest heavily and generate little FCF
  • The ROIC-WACC spread is the scorecard for capital allocation quality — it explains why asset-light franchises (Visa, Google, LVMH) trade at vastly higher multiples than capital-intensive businesses with similar growth rates

Question 1 of 30 answered

Company A earns $100M NOPAT, has a 20% ROIC, grows at 5%, and a 10% WACC. Company B also earns $100M NOPAT, has a 12% ROIC, grows at 5%, with the same 10% WACC. Which is more valuable and by how much?

ABoth are equally valuable since they have the same NOPAT and growth rate
BCompany A: EV = $100M × (1−5%/20%) / (10%−5%) = $100M × 0.75/0.05 = $1,500M; Company B: EV = $100M × (1−5%/12%) / (10%−5%) = $100M × 0.583/0.05 = $1,167M; A is worth 29% more despite identical earnings and growth — because its higher ROIC means less reinvestment is needed to achieve the same growth, so more free cash flow is available
CCompany B is more valuable because it has a higher reinvestment rate
DCompany A: $1,000M; Company B: $1,000M — value depends only on NOPAT/WACC
