Valuation Multiples
DCF Modeling
A discounted cash flow values a business as the present value of the cash it will generate, discounted for time and risk. It runs as a fixed, repeatable sequence of steps. Project the free cash flows, discount them at the cost of capital, add a terminal value, and bridge to a price per share. Done carefully it forces you to state every assumption behind a valuation, and shows exactly where value comes from. It is the most complete way to value a company, and the core skill behind serious equity research.

DCF Modeling
LEARNING OBJECTIVES
IMPORTANCE
The DCF is where the whole curriculum assembles: free cash flow, the cost of capital, the enterprise-to-equity bridge, and the exit multiple. It is the one method that values a business from the inside, on what it will produce, not on what the crowd will pay. Its power is that independence; its weakness is its assumptions.
The central insight: A DCF is only as good as its assumptions. Its discipline is not false precision; it is an honest range.
INTELLECTUAL ORIGINS
John Burr Williams stated it in 1938: the value of any asset is the present value of the cash it will pay its owner over time. Everything since is machinery on that one sentence, how to forecast the cash, choose the rate, and value the years beyond the forecast.
THE DCF IN EIGHT STEPS
Step 1. Forecast . Project FCFF over an explicit period, usually five to ten years.
Step 2. Build the (). Unlevered cash flow belongs to all funders, so it is discounted at the blended cost of capital.
Step 3. Discount each year to today. Convert each future cash flow to present value.
Step 4. Calculate the . Capture the cash flows beyond the forecast, usually the majority of the value, by one of two methods, then discount it back.
Step 5. Sum to enterprise value. Add the two present-value pieces.
Step 6. Bridge to equity value. Strip out the claims that rank ahead of shareholders.
Step 7. Solve for the implied share price. Translate equity value into a per-share figure.
Step 8. and sanity checks. The output is fragile, so stress it.
THE THEORY IN DEPTH
A discounted cash flow model is the purest expression of what a business is worth: the cash it will produce, valued in today's money. Every shortcut in valuation is ultimately an approximation of this one idea. Understanding the theory beneath the model is what stops it from becoming a spreadsheet you trust blindly.
What a DCF is really saying
A DCF rests on a single principle: a business is worth the for its owners over its life, converted into .
No story and no momentum can change what a company is fundamentally worth.
Everything in the model exists to answer two questions: how much cash, and when.
Why future cash must be discounted
A pound received in ten years is worth less than a pound today, for two reasons:
Discounting converts future cash flows into their value today. The rate used, the discount rate, captures both the time and the risk. A higher rate values the future less; a lower rate values it more.
Where the value actually comes from
A DCF has two parts:
In most models the terminal value is the larger share of the total. This is the DCF's great strength and its great danger: most of the answer depends on assumptions about the distant future, which no one can know precisely.
Why a DCF is only as good as its assumptions
A DCF feels precise because it produces an exact number. That precision is an illusion.
Small changes in growth or in the discount rate can move the answer dramatically.
This is why a serious analyst does not seek a single correct value, but a reasonable range, and always tests how sensitive the answer is to its assumptions. The model does not remove judgement. It organises it, and makes every assumption visible.
COMPARISON
| Terminal value method | What it assumes | Best when |
|---|---|---|
| Perpetuity growth (Gordon) | Cash flows grow forever at a low, steady rate | Stable, predictable businesses |
| Exit multiple | The business is sold at a peer multiple of EBITDA | A clear, comparable peer set exists |
| Average of both | Neither single method is fully trusted | The default discipline, with a cross-check |
REAL COMPANY APPLICATION: THE HONEST COMPANY
The same eight steps, applied to a real company. The full model is in Equity Research, under the Honest analysis.
Honest is the cleanest possible case, because it carries cash and no debt.
1. FCFF. The company runs at an operating loss today, so the value rests on a forecast margin inflection, from breakeven toward about 6.5% by 2030 on low-single-digit organic growth.
2. WACC. The cost of equity from CAPM is 4.42% + 1.45 × 4.24% ≈ 10.6%, and with only a small lease the blended WACC the model uses is about 10.34%. A company with debt would blend in a lower after-tax cost of debt and land beneath this.
3. Discount each year's cash flow at 10.34%.
4. Terminal value by a ~2.5% perpetuity growth and a peer exit multiple, averaged; it carries most of the value.
5. Enterprise value is the sum of the two present-value pieces.
6. Bridge: with no debt, simply add the $89.6M of net cash.
7. Implied price: divide by about 113M shares. The base lands near $3.81 against a market price of $3.60 as of 28 June 2026 (Q2 FY26), and the net cash alone is about $0.80 a share, a floor under a thin business.
8. Sensitivity: across the scenarios the value runs from roughly $2.05 in the bear case to $5.56 in the bull. The DCF produces a span, not a point.

IN SUMMARY
A DCF values a business as the present value of its future cash. Forecast unlevered free cash flow, discount it at the cost of capital, add a terminal value, sum to enterprise value, bridge to equity, and solve for the implied price, then stress it. Honest shows the method at its cleanest: with effectively no debt the rate is close to the 10.34% cost of capital, and the bridge simply adds the net cash. The output is a range, and the discipline is to demand a margin of safety against the base.

REFLECTION QUESTIONS
The cash a business generates for everyone who funded it, before financing, projected over an explicit forecast and discounted to today. It is the cash flow a DCF runs on.
In a DCF of Honest, each forecast year's FCFF is built from a revenue and margin path, then discounted; because the company runs at a loss today, the value rests on a forecast margin inflection toward about 6.5% by 2030.
FCFF is unlevered, so discounting it gives enterprise value, the figure a DCF produces before bridging to equity.
The weighted average cost of capital: the blended return required by all a company's funders, equity and debt, used to discount unlevered cash flow. A company with no debt has nothing to blend, so its WACC equals its cost of equity.
Honest carries only a small lease, so its WACC of about 10.34% sits slightly below its cost of equity. A more indebted company would blend in more low-cost debt and fall further beneath it.
The discount rate sets how heavily future cash is penalised for time and risk, and small changes in it move the valuation substantially.
The return shareholders require to hold a stock, estimated with the capital asset pricing model: the risk-free rate plus the stock's beta times the equity risk premium. It is the discount rate for equity cash flows and a component of WACC.
For Honest: a risk-free rate of about 4.42%, plus a beta near 1.45 times an equity risk premium of about 4.24%, gives a cost of equity of roughly 10.6%.
The cost of equity is the hurdle a business must clear for shareholders, and for a debt-free company it is the whole discount rate.
The value of every cash flow beyond the explicit forecast, usually the majority of a DCF's total. It is estimated either by assuming steady perpetual growth or by applying a peer exit multiple, then discounted back like any other cash flow.
A DCF of Honest sets terminal value with a perpetuity growth around 2.5% and a peer exit multiple near 13x, averaged, and it carries most of the company's value.
Because the terminal value dominates, its assumptions deserve the most scrutiny, and they must reflect a normalized steady state, not a peak year.
The constant rate at which cash flows are assumed to grow forever in the perpetuity method. It must be low and sustainable, no higher than long-run economic growth, because no company can outgrow the economy indefinitely.
A DCF of Honest uses a perpetuity growth of about 2.5%, at the GDP ceiling, with no premium because a small, low-moat brand earns no structural growth advantage.
A growth rate set too high inflates the terminal value without limit, which is why g is capped near GDP and cross-checked against the exit multiple it implies.
A grid that recomputes the valuation across a range of discount rates and growth rates, turning a single estimate into a span. It is how a DCF is honestly presented, because the output is too sensitive to inputs to be a single number.
Across its scenarios Honest's value runs from roughly $2.05 in the bear case to $5.56 in the bull, with a base near $3.81. The DCF produces a range, not a point.
The sensitivity table shows exactly which assumptions the value depends on and forces an honest range, which is the discipline of a DCF.
A higher discount rate values the future less, a lower one values it more. It is one of the two levers that most influence a DCF's answer.
Terminal value is usually the largest part of a DCF, which is its great strength and its great danger, because it rests on long-run assumptions.
Present value is the whole idea behind a DCF. A pound in ten years is worth less than a pound today, and discounting says exactly how much less.
Free cash flow is the raw material of a DCF. The model forecasts it, discounts it, and sums it to reach intrinsic value.
