Cash Flow Statement
The cash flow statement is one of the three core financial statements, showing all actual cash inflows and outflows over a reporting period, organized into operating, investing, and financing activities.
The cash flow statement bridges the income statement and balance sheet by tracking the movement of actual cash through the business. While the income statement reflects accounting profits (which include non-cash items like depreciation, amortization, and stock compensation), the cash flow statement shows what really happened to cash. The famous accounting adage — 'revenue is vanity, profit is sanity, cash is reality' — underscores why the cash flow statement is often the first document sophisticated investors examine.
Operating cash flow (also called cash from operations or CFO) is the most watched section. It starts with net income and adds back non-cash charges (depreciation, amortization, stock-based compensation), then adjusts for changes in working capital accounts. An increase in accounts receivable, for example, is a use of cash (you billed customers but have not collected yet) and reduces operating cash flow. A company with net income of $10 billion but operating cash flow of $6 billion has significant working capital deterioration or inflated earnings from non-cash gains worth investigating.
Investing activities capture capital expenditures, acquisitions, asset sales, and purchases or maturities of investments. This section shows how aggressively the company is investing in future growth. Microsoft's investing activities often show large net cash outflows reflecting Azure data center buildout, acquisitions like Activision, and purchases of marketable securities. A company with very low capex relative to depreciation may be 'harvesting' its asset base — milking existing assets without reinvesting, which can boost short-term cash flow at the cost of long-term competitiveness.
Financing activities show cash flows related to debt issuance and repayment, equity issuance, share buybacks, and dividend payments. Apple's financing activities regularly show massive net cash outflows — sometimes $80-100 billion per year — reflecting the combination of dividend payments, share repurchases, and bond maturities, funded by operating cash inflows and new bond issuances. Reading this section tells the full story of a company's capital return program.
Free cash flow is derived directly from the cash flow statement: operating cash flow minus capital expenditures (from the investing section). This is the most important derived metric from the statement, and it explains why the cash flow statement deserves as much attention as the income statement in any thorough fundamental analysis.
