Option to expand
Valuation & CompsThe right to commit further capital later if a first phase works, which is why a phased rollout is worth more than the same project committed in full.
Also written: growth option, option to scale, staged investment
Building in tranches buys information. The first phase of a fibre rollout, a store format, a production line or a clinical programme reveals whether the economics are what the plan assumed, and only then does the next tranche get funded.
A DCF of the full committed build prices none of that, because it assumes every tranche happens. Valuing the first phase on its own cash flows and treating the rest as a right that will be exercised only in the good states is closer to how the investment will actually be run.
The consequence for deal work is that the option is frequently the reason a price looks high. A buyer paying above a standalone DCF for a business with a permitted expansion, spare licensed capacity or an established rollout template is paying for the right, not overpaying for the asset, and being able to say which is the difference between a defensible bid and a bad one.
The test is exclusivity. An option is only worth something if the holder alone can exercise it. A rollout template any competitor can copy, or a licence available to all applicants, gives everyone the same right and therefore prices at nothing.
Worked example
A retailer proves a new format in ten stores at a cost of 30, with the option to build a further ninety at 3 each if the pilot works.
Committed, all one hundred stores are in the DCF and a weak pilot drags the whole programme's value down. Staged, only the ten are committed, and the ninety are funded only in the state where they are worth building.
The staged version is worth more for the same underlying business, and the difference is the value of not having to decide yet.
