Earnings quality: net income, operating cash flow, and free cash flow

Net income measures profit on an accrual basis. Operating cash flow (OCF) measures net cash from operating activities; under the indirect method, non-cash items and working-capital movements reconcile it to net income. Recognizing revenue does not mean cash has already been collected.

Free cash flow (FCF) commonly means OCF less cash capital expenditures, but it is not a uniformly defined GAAP measure. Check the company's definition and reconciliation before making a cross-company comparison.

This is an independently constructed hypothetical example, not a real company. All amounts are in USD millions. Start with net income of 100, add depreciation of 20 and stock-based compensation of 10, subtract a 50 increase in receivables and a 15 increase in inventory, then add a 5 increase in payables. Assume all other adjustments are zero.

OCF = 100 + 20 + 10 − 50 − 15 + 5 = 70. With cash capital expenditures of 40 for the same period, FCF under this definition is 70 − 40 = 30. Adding back stock-based compensation does not remove its economic cost; also examine dilution and repurchases.

Continue the example with prior-year net income of 80, OCF of 90, and cash capital expenditures of 20. Net income grows 25%, OCF falls 22.2%, and FCF drops from 70 to 30, or 57.1%. This divergence alone establishes neither fraud nor failed growth.

Investigate whether sales are still within normal credit terms, whether inventory supports orders, and whether investment is expanding capacity. Follow subsequent collections, inventory write-downs, and capacity utilization. Management's explanation remains a hypothesis until supported by evidence.

The reverse also matters: inventory liquidation or slower supplier payments can improve near-term OCF without stronger demand. These are analytical questions, not diagnoses of the companies on this site.

Read the statement's reporting window first. If first-half OCF is 120 and Q1 OCF is 50, standalone Q2 is 70, not 120. Q3 can similarly be derived from nine-month less six-month totals. Match fiscal-year start, currency, and restatement version; do not subtract across fiscal years. Use reported quarterly EPS rather than subtracting cumulative EPS.

Trailing twelve months (TTM) sums four consecutive reported quarters; it is not the latest quarter multiplied by four. TTM operating cash flow margin uses total OCF divided by total revenue, not an unweighted average of quarterly ratios. Missing quarters remain missing rather than becoming zero.

YoY compares the same fiscal quarter a year earlier; QoQ compares the immediately preceding fiscal quarter. For seasonal businesses, use YoY and TTM together, while retaining the effects of acquisitions, currency changes, and unusual items.

SEC non-GAAP guidance cautions that FCF definitions differ and may omit mandatory debt service or other non-discretionary expenditures. The example's 30 therefore does not establish dividend capacity of 30 or guarantee next quarter's receipts.

Reconcile cash payments for equipment with investment figures in company presentations. Record non-cash asset acquisitions and company-specific adjustments separately. Lower capital expenditures can lift FCF simply because investment has been deferred, not because competitiveness improved.

This framework is for general non-financial companies. Banks and insurers have different balance-sheet structures and should not be ranked using the same cash-flow thresholds.

Select a fiscal quarter on a company page to compare revenue, EPS, margins, and OCF with the year-ago and preceding quarters. Use the chart to locate when a divergence began. Business revenue and guidance follow the period shown in the separate latest-quarter business and outlook section.

The dashboard reports OCF. Calculating FCF also requires cash capital expenditures for the same period from the source filing, reconciled to the company's definition. Investigate changes using the cash flow statement notes and Management's Discussion and Analysis (MD&A), recording the fiscal period, definitions, and access date.
