Free cash flow and FCF yield

What free cash flow means

Free cash flow (FCF) aims to measure cash left after spending needed to operate and maintain or expand business assets. A common approximation is operating cash flow minus capital expenditure. The definition should fit the sector and remain consistent.

FCF is not cash with no claims on it. Debt, acquisitions, distributions, and future needs may compete for it.

From earnings to cash

Earnings include accounting estimates; cash flow records actual movements. Working capital, share-based compensation, tax, and investment create differences. A one-year gap may be normal; repeated gaps need an explanation.

FCF yield

In simple terms, FCF yield is FCF divided by market value. €100 million of FCF against a €2 billion market capitalisation equals 5%. To compare different debt structures, firm-level FCF and enterprise value may be more appropriate.

A high yield does not prove undervaluation: cash may be at a peak, require reinvestment, or be about to decline.

Normalising

Study several years, cycles, and required investment. Young companies may report negative FCF while investing; mature firms may temporarily improve it by delaying spending. Adjustments help only when transparent.

What to watch

• earnings-to-cash conversion;
• maintenance versus growth capex;
• working capital;
• debt, dilution, and acquisitions;
• definition consistency.

Common mistakes

Using one year, adding back share compensation without considering dilution, and comparing incompatible sectors create fragile conclusions. FCF yield is a question about price and sustainability, not a “cheap” stamp.

Build a research note

Analysis becomes more useful when it can be checked later. Summarise the business, key revenue drivers, cost structure, and uses of capital. Record the source and date for figures; mixing fiscal years, currencies, or adjusted metrics can create misleading comparisons.

Separate facts, estimates, and judgements. “Margin was 18%” is a historical fact. “It may reach 22%” is an estimate. “The advantage is durable” is a judgement requiring evidence. This distinction shows where the thesis is most vulnerable.

Build at least three scenarios and identify the assumptions that move value most. Forecasting every quarter is unnecessary: the aim is to understand which variables drive the outcome and which combination is already implied by the price.

Signals to monitor

• organic revenue and margin development;
• conversion of earnings into cash;
• debt, maturities, and dilution;
• returns on incremental capital;
• customer and competitor behaviour;
• management’s capital allocation.

Watch cash conversion, reinvestment needs, and debt before interpreting a change in FCF yield. Update the valuation from those facts, not from the share price alone.
