Free Cash Flow: The Lifeblood of Business
Why cash flow matters more than earnings for value investors.
Free cash flow (FCF) is the cash a company generates from operations after paying for capital expenditures. It represents the money actually available to shareholders.
Why FCF matters
Net income is an accounting number — it includes non-cash items like depreciation and can be influenced by accounting choices. FCF is harder to manipulate because it tracks actual cash movement.
A company can report strong earnings while bleeding cash (bad), or report modest earnings while generating robust cash flow (good).
FCF Margin
FCF as a percentage of revenue. A 10%+ FCF margin suggests a capital-efficient business. Compare FCF margin to net margin — a wide gap may signal aggressive accounting.
FCF / Net Income (Earnings Quality)
This ratio measures earnings quality: - Above 1.0 → The company generates more cash than it reports as profit (high quality) - Around 1.0 → Earnings are well-supported by cash - Below 0.7 → Earnings may be overstated or the business requires heavy reinvestment
What companies do with FCF
- Pay dividends
- Buy back shares (reduces shares outstanding, increases per-share value)
- Pay down debt
- Reinvest in growth (R&D, acquisitions, expansion)
- Build cash reserves
