Free Cash Flow: What Is Left After the Business Is Funded
Free cash flow is cash generated by operations minus capital expenditure. In plain terms: the money the business produced, less the money it had to put back in to keep producing. What remains is available to repay debt, pay dividends, buy back shares, or fund an acquisition.
Both inputs come straight off the cash flow statement, which is why the measure is common. It is one subtraction away from a published figure.
Why it gets watched more closely than earnings
Reported profit involves a large number of judgements. Depreciation schedules, revenue recognition timing, provisions, inventory valuation, capitalisation decisions. All of these are legitimate accounting choices, all of them are disclosed, and all of them move the earnings line without any cash changing hands.
Cash flow contains fewer such judgements. Money either arrived or it did not. This does not make it immune to management, and the section below covers how it gets managed, but the surface available is smaller. That difference is the whole reason both figures get reported and both get read. The mechanics of the gap between them are covered in cash flow vs profit.
The capital expenditure problem
The subtraction hides a real difficulty: capital expenditure comes in two kinds and the statement does not separate them.
Maintenance capex keeps existing operations running. Replacing worn machinery, refreshing stores, renewing hardware. Growth capex builds new capacity that does not exist yet: a new plant, a new region, a new product line.
A company spending heavily on growth capex will show weak free cash flow while building something that may generate substantially more cash later. A company spending nothing on either will show strong free cash flow while its asset base degrades. The same number describes both situations and the interpretation is opposite.
Companies rarely split the two, because the boundary is genuinely blurry. Some disclose an estimate in the annual report, which is one of the more useful things to look for when reading one. What can be done without disclosure is comparing capex to depreciation over several years: capex persistently below depreciation suggests an asset base being consumed rather than maintained.
How it can still be managed
Free cash flow is harder to flatter than earnings, not impossible. The usual levers are timing.
- Stretching payables. Paying suppliers later moves cash out of the period. The obligation is unchanged, only the timing moved.
- Pulling collections forward. Discounts for early payment bring cash in sooner at the cost of margin.
- Deferring capex. Postponing a scheduled replacement improves this year at the expense of a later one.
- Leasing rather than buying. Changes where the cost appears in the statements without changing the economics much.
Each of these is visible in the working capital lines when several periods are read together, and none of them is repeatable indefinitely. A single strong quarter says less than a multi year pattern.
Free cash flow yield
Dividing free cash flow per share by the share price produces a yield, which allows comparison against other uses of capital and across companies. Unlike the P/E ratio, it is not distorted by non cash charges, which makes it steadier for asset heavy businesses and for companies carrying large amortisation from past acquisitions.
It has its own distortions. A company in a heavy investment phase will show a poor yield precisely because it is building something. A company harvesting a declining business will show an excellent one. The yield does not distinguish between the two, and nothing about a high yield indicates that a share is mispriced.
When it is negative
Negative free cash flow means the business consumed more cash than it produced, which has to be funded from existing cash, new borrowing or new shares. For an early stage company building capacity this is expected and unremarkable. For a mature company in a stable industry it is a different observation, and the useful question is which of the two situations the numbers describe, which requires reading the capex line rather than the total.
Cash generation next to the rest
Cash generation is one input to the fundamentals reading EquityBias produces per covered stock. That reading sits alongside price behaviour, analyst activity and news sentiment, and where they disagree the disagreement is reported rather than averaged.
