What Is It?
Free Cash Flow (FCF) is the cash a company generates after accounting for capital expenditures required to maintain or expand its asset base. It represents cash available for debt repayment, dividends, share buybacks, or reinvestment.
Origin
Free cash flow concepts emerged from 1980s value investing (Buffett, Klarman) and LBO modeling. It addresses the limitation of accounting earnings by showing actual cash available to owners. Modern valuation increasingly centers on FCF rather than accounting profit.
Why It Matters
FCF determines a company's ability to return capital to shareholders, fund acquisitions, and survive downturns. Companies can manipulate earnings but not cash. FCF-based valuations often diverge from earnings-based multiples, creating investment opportunities.

Market Mechanics
FCF equals Operating Cash Flow minus Capital Expenditures. Unlevered FCF (before debt service) values the enterprise; levered FCF (after debt) values equity. Growth companies often show negative FCF due to heavy investment; mature companies generate consistent positive FCF.
How It Behaves
FCF conversion (FCF/net income) varies by industry and lifecycle. Asset-light businesses convert at higher rates than capital-intensive operations. Working capital changes create quarter-to-quarter volatility. Stock compensation creates divergence between cash and GAAP metrics.
