Also called Sales, Top line

Revenue

Total sales over the trailing twelve months, before any cost is subtracted.

Updated 2026-09-03

Revenue is total sales over the trailing twelve months, before any cost is subtracted. It is the top line, and it is the least ambiguous number on the income statement.

Angie uses it for two things. It is the denominator of fcf margin, and more importantly it is the source of the growth rate rate. Free cash flow over a short window is dominated by one-off tax, working-capital and capex items, which makes stable businesses read as though they were shrinking. Revenue is the steadier signal of what the business is actually doing.

Growing cash flow at the revenue rate assumes the margin holds. That is a real assumption and it can be wrong. Angie flags a company whose revenue is rising while cash flow lags by five points or more, and drops its confidence rather than quietly overstating the value.
