Every seller's forecast rises. Revenue climbs a few points faster than it has, margins widen a little each year, and the capital needed to deliver it all stays modest. Buyers have read hundreds of these, and most treat the seller's forecast as a statement of hope. They build their own model from the history, at their own assumptions, and set the seller's spreadsheet aside on the first day.
The last span of the third bridge is about making a forecast a buyer cannot set aside. The first three spans made the business's cash real: maintenance spending stated, working capital measured and clean, tax reconciled, the perimeter of the sale written down. All of that is history. A buyer who models instead of applying a multiple is paying for the future, and this span is where the business shows that its future can be computed from its past.
What the measure is
The measure this span reaches is free cash flow to the firm: NOPAT, plus depreciation and amortization, less capital spending, less the change in working capital. It is the cash the business produces for everyone who has provided its capital, before any of them is paid, and it is the figure a discounted cash flow values.
Each earlier span produced one of its components. The first stated the capital spending and the asset base behind it, the second stated working capital and its change, and the third stated the tax and the business that bears it. None of them could say how those figures will move. As a historical number, free cash flow to the firm tells a buyer what the business did. As a forecast it is what the buyer is actually buying, and it is worth something only if the forecast can be trusted.
So it comes last. A forecast built before the components are stated projects numbers nobody has checked, while one built after them projects numbers a buyer has already accepted for the past.
The four drivers
What moves NOPAT to free cash flow to the firm
Three drivers make the cash forecastable; the fourth produces the inputs the valuation consumes, and is covered at the anchor.
NOPAT
- BudgetingProves the business can plan its year and hit the plan, with every variance explained
- Forecast ModelBuilds an integrated forecast that reproduces the history and whose DCF governs
- Reinvestment ReturnMeasures what reinvested cash earns, so the forecast's growth is computed from the record
- Enterprise Value FileProduces the inputs the valuation consumes: return on capital, competitors, cost of capital, scenarios
Free cash flow to the firm
Budgeting gives the forecast its first evidence: a record of the business planning a year and hitting the plan. The leads build the budget for their own seats before the year starts, the finance seat assembles it by month down to capital spending and working capital, and the monthly package explains every material variance in the words of the lead responsible. Two years of budgets that landed close at EBITDA show the process exists and is honest. They are a small sample, though, and the framework says so, pulling the forecast's assumptions toward the base rate for businesses of this size in proportion to how short the record is.
Forecast Model turns the budget into a five-year forecast in which the profit and loss, balance sheet and cash flow are linked. Its first year is the approved budget, its revenue is built from customers and their observed retention, and its capital spending, working capital and tax come from the schedules the earlier spans built. A buyer can trust it because it reproduces the last two years when run on their actual drivers. The value it produces, at a cost of capital built from the market, is the governing number, and the value implied by comparable transaction multiples sits beside it as the test of price.
Reinvestment Return measures what the business earns on the cash it puts back in. Every growth project gets a line in a register before it is approved, saying what it will cost and what it should earn, and is measured afterwards against what it did earn. The register yields a return on reinvested capital, and that return sets the ceiling on the forecast's growth: no year grows faster than its reinvestment rate multiplied by the return, unless a documented cause such as a price rise accounts for the difference.
Enterprise Value File produces the inputs the valuation uses that no other driver produces. They include the return on all of the business's capital, a map of competitors with the evidence of what holds them off and for how long, the cost of rebuilding the business, the cost of capital, the base rates and scenarios behind the margin of safety, a log of where price and value have diverged, and the holder's own return. Its work is raw material for the valuation and changes nothing in the business, so it is covered in the essay on what free cash flow to the firm is worth.
Growth as a product
The idea at the centre of this span is that growth can be computed. It is the product of two things the business can measure: how much of its after-tax profit it reinvests, and what that reinvestment earns.
Growth the record can support
Illustrative. Growth in operating profit is the share of NOPAT reinvested multiplied by the return that reinvestment earns; what is not reinvested is free cash flow. A claimed growth rate, divided by the same reinvestment, gives the return the claim needs the register to show.
A business that reinvests 30 percent of its NOPAT at a 20 percent return grows its operating profit by about 6 percent a year, and the other 70 percent is free cash flow. To grow faster it has to reinvest more, which leaves less cash today, or earn more on what it reinvests, which the register either shows or does not. A forecast that shows 10 percent growth from the same business with the same reinvestment is claiming a return of a third on new capital. The buyer will ask where that return appears in the history, and if the register cannot show it, the buyer will cut the growth back to what the record supports, or lower.
That shifts what the seller has to defend. A growth rate on its own is an opinion. A reinvestment plan is a budget and a return is a record, and a buyer who disagrees with either has to name the number it disputes and say why.
What it does to value
The drivers on this span do very different things to value. Budgeting moves none. A budget with a record makes the forecast's first year credible, and the buyer's discount for an unproven plan shrinks as the record lengthens, but the business produces the same cash whether it budgets or not. The effect is on price and certainty, so the driver is done for the confidence it gives a buyer and carries no rank.
Forecast Model ranks ninth on the bridge. It leaves the cash flow and the rate alone and narrows the spread of outcomes the buyer has to allow for. A model that reproduces its own history and has passed an independent review shrinks the chance that the model is wrong to the size of its back-test variance, and the margin of safety shrinks with it. The multiple itself, and any explained line in the gap between the DCF and the multiple, are price and do not count.
Reinvestment Return ranks second, behind only working capital, because it is the one operating driver on the bridge that creates growth value. The register moves the forecast's growth from zero credit, which is what a buyer gives a line drawn upward, to full credit at the measured return. It also raises the return, because stopping projects that earn below the cost of capital lifts the return on every dollar reinvested after them. Growth adds value only when the return on new capital exceeds its cost, and the register shows which projects clear that bar.
Enterprise Value File comes tenth and last. Like Forecast Model, it narrows the uncertainty around the number without moving it.
How the drivers depend on each other
The drivers on this span are built in order, each on the one before it and on the earlier spans.
The budget needs leads in every seat, from the second bridge's management install, because the people who run the seats are the ones who build a bottom-up budget. It needs a monthly package closed on a fixed date, since budget-to-actual is a page of that package. And it reaches cash only if its capital spending comes from the replacement plan and its working capital from the peg's days, which the first and second spans of this bridge produced.
The model's first year is the budget, so the model needs the budget. Its capital spending, working capital and tax lines are linked to the earlier spans' schedules, so a change in the replacement plan moves the forecast without anyone touching the model.
The register is the growth half of the thirty-six months of capital spending classified as maintenance or growth, seen project by project, so it needs that classification. Growth working capital is the part of the working-capital build a project caused, which can only be isolated from a history kept on one definition. And reconciling growth to reinvestment and return is something the model does, so the model has to exist first.
The value file sits on top of all of it. Its return on total capital, its scenarios and its cost of capital are computed from the model and the register, and they are only as good as those are.
How the span comes undone
Each of the ways this span comes undone looks like nothing in the month it starts.
The first is forecasts that miss without explanation. A finance seat changes hands, the budget calendar slips, a year's budget is set late and never compared with the result, and the record that made the forecast credible has a hole in it. What prevents this is putting the calendar and the variance commentary into the structure of the finance seat and the monthly package, and rolling the model forward each year and testing it again on the year just closed, so a failed back-test is visible.
The second is growth spending that stops being tracked. A project approved in a hurry outside the register is never measured. The fix is to make the register the only route to approval.
The third is growth bought with margin. Revenue rises, each new dollar carries less profit than the old ones, and the reported margin hides the drift for a year or two. Reporting incremental margin, the change in operating profit divided by the change in revenue, beside reported margin every year and by line brings it into view.
The fourth is a forecast whose growth outlasts the year it was meant to settle. Every business's advantage fades, and the forecast has to name the year its return on new capital falls to the cost of capital. A forecast that keeps pushing that year out keeps claiming growth value the business has not shown. Re-deriving the convergence year and the incremental margin from the register and the cost split with every annual forecast catches a drift in either at the next budget, long before a sale.
The value file has decay of its own, which the anchor essay covers: a competitor map that goes stale, a cost of capital that drifts from the market, scenarios that collapse back into one case, an acquisition credited with the organic return, and a holder's return nobody measures.
Crossing the span
The span is crossed when the business can show a budget record that makes a projection credible, and an integrated forecast, built on the same drivers as the history, whose discounted value a modelling buyer can test without rebuilding it. That completes the third bridge. The business arrives at free cash flow to the firm with its cash stated, its future forecast from evidence and the inputs to its own valuation in a file, and the essay on what free cash flow to the firm is worth takes up what that valuation is and who will pay it.
