A valuation can look rigorous while depending on an unsupported terminal growth assumption. Revenue grows, margins improve and reinvestment remains unusually low. The spreadsheet produces a value, but the operating story is incomplete.
Discounted cash-flow valuation requires consistency between the business model, cash generation and required return.
Choose the valuation perspective
- Free cash flow to the firm is discounted at an appropriate weighted cost of capital.
- Free cash flow to equity is discounted at the required equity return.
The CFA Institute’s valuation material distinguishes these approaches. Mixing their cash flows and discount rates can misstate the result.
Define the perspective before forecasting and preserve it through the value bridge.
Build the operating forecast
Connect revenue to volume, pricing and customer economics. Explain margins through the cost structure and capabilities required.
Forecast reinvestment in assets, development and operating working capital. Growth generally needs a mechanism and resources; it is not merely a percentage added to revenue.
A hypothetical service business can scale revenue with modest physical assets but may still need software investment, customer acquisition and additional receivables.
Make the transition credible
An explicit forecast should lead to a sustainable operating condition rather than jump suddenly to an idealized terminal year.
Consider competitive pressure, maintenance needs, capacity and the useful life of assets or capabilities. Temporary advantages should not automatically persist forever.
Use scenarios where the route to maturity is uncertain. A single smooth curve can conceal significant business-model risk.
Understand terminal value
In a constant-growth firm-cash-flow model, terminal value at the end of the explicit period equals the following period’s cash flow divided by WACC less the growth rate. This requires a compatible sustainable-growth assumption and a discount rate above growth.
| Hypothetical terminal value | Value |
|---|---|
| Next-period free cash flow | €2,000,000 |
| WACC | 8% |
| Sustainable growth | 2% |
| Terminal value (2,000,000 / (0.08 − 0.02)) | about €33.33 million |
That value applies at the future valuation date. It must still be discounted back to today.
Do not treat terminal growth as free. The reinvestment and return assumptions need to support it.
Reconcile operating value to the claim being valued
Operating enterprise value is not automatically the amount attributable to ordinary shareholders.
Assess excess cash, nonoperating assets, debt and other relevant claims using consistent definitions. Avoid adding cash already needed to generate the forecast as though all of it were freely distributable.
The bridge should be explicit enough for a reviewer to identify omissions or double counting.
Test what drives the conclusion
Show sensitivity to operating assumptions, discount rates and terminal conditions. Explain the share of value arising beyond the explicit forecast.
Compare the implied economics with credible market and operating evidence. A DCF is an explanation of expected cash, not proof that a negotiated price is fair.
Before using the next valuation, ask whether its growth, margins and reinvestment could occur together. A coherent business story is the foundation of a useful model.
