Earnings can be manipulated through accounting choices. Revenue can be inflated through aggressive recognition. But cash is cash. Free cash flow strips away the accounting and shows you how much real money a company is generating.
The Formula
Free Cash Flow = Operating Cash Flow - Capital Expenditures
Operating cash flow comes from the cash flow statement. Capital expenditures (capex) are the money spent on maintaining and expanding physical assets like buildings, equipment, and technology.
Why It Matters More Than Earnings
Earnings include non-cash items. Depreciation, amortization, stock-based compensation, and other accounting entries affect earnings but do not involve actual cash moving in or out.
Cash pays the bills. A company can report profits while running out of cash. Free cash flow tells you whether the company is actually generating enough money to fund its operations, pay dividends, buy back stock, reduce debt, and invest in growth.
Harder to manipulate. While earnings can be adjusted through accounting choices, cash flow is more concrete. Either the cash came in or it did not.
How to Interpret Free Cash Flow
Positive and growing FCF: The company generates real cash and the trend is improving. This is what you want to see.
Positive but declining FCF: The company still generates cash, but the trend is weakening. Worth investigating why.
Negative FCF: The company is spending more than it generates. This can be normal for high-growth companies investing heavily, but it is a red flag for mature companies.
Free Cash Flow Yield
FCF Yield = Free Cash Flow Per Share / Stock Price
This tells you how much cash the company generates relative to its stock price. A higher yield suggests better value.
- FCF yield above 5%: Potentially attractive
- FCF yield of 3-5%: Reasonable
- FCF yield below 2%: The market expects significant growth to justify the premium
What Companies Do With Free Cash Flow
- Pay dividends to shareholders
- Buy back shares to increase per-share value
- Pay down debt to strengthen the balance sheet
- Invest in growth (acquisitions, R&D, expansion)
- Build cash reserves for flexibility
How management allocates free cash flow tells you a lot about their priorities and competence.
Red Flags
- A company reporting strong earnings but negative free cash flow
- Free cash flow consistently lower than reported net income
- Growing revenue but shrinking free cash flow
- Excessive capital expenditures with no clear return
