Capital cycle and unit economics

The buildout is a capital cycle. Money floods into an industry whose returns look extraordinary, capacity follows, and the returns are competed away or they are not. The companies worth owning through a cycle are the ones whose economics survive it. This instrument reads those economics straight from the filings.

What it measures#

Capital intensity is capital expenditure over revenue, and capital expenditure over depreciation shows whether the asset base is growing or merely being maintained. Return on invested capital is after-tax operating income over the capital employed, set against the cost of capital the dossier uses elsewhere, so the spread is visible. Incremental operating margin is the change in operating income per unit of new revenue, the clearest sign of operating leverage or its absence. Stock-based compensation is stated as a share of revenue and of free cash flow, and cash conversion compares free cash flow with net income. Each ratio is published for the trailing period and as a quarterly history, with its formula written out.

Assumptions#

Filed figures are taken at their latest filed values and mapped from XBRL concepts through a versioned concept map; where a fourth quarter must be derived from an annual figure, the row says so. Invested capital is equity plus debt less cash, one common definition among several, and the definition block names it. The cost of capital is the author's input, as everywhere in the lab.

When it misleads#

A ratio is only as good as its denominator: return on capital during a capacity build understates what the assets will earn once they are running, and overstates it once the cycle turns. Incremental margins over a single quarter are noisy and are read over several. Stock-based compensation is a real cost that free cash flow ignores, which is why both measures are shown together. A company that reports under a different taxonomy or on an annual basis is compared with care.

How the lab uses it#

The capital-cycle section is where the thesis meets the balance sheet: whether the growth the price requires can be funded, at what return, and with how much dilution. In a young company it is often the most important section, and the memo's key drivers usually point back to it. The demo below computes the same ratios from illustrative inputs so a reader can see how a change in capital intensity or margin moves the return on capital.
