Operating Cash Flow
Operating cash flow, also called cash flow from operations, is the net cash provided by or used in a company’s operating activities during a reporting period.
Where it appears
The statement of cash flows has three major sections:
- operating activities
- investing activities
- financing activities
Operating cash flow focuses on cash tied primarily to ordinary business activity.
A company can report positive net income and negative operating cash flow, or the reverse, without an accounting error.
The timing of cash and accrual earnings differs.
The indirect-method bridge
A simplified framework is:
Net income + noncash expenses − noncash gains ± changes in operating assets and liabilities = Operating cash flow
Common adjustments include:
- depreciation and amortization
- stock-based compensation
- deferred taxes
- impairments
- receivable changes
- inventory changes
- payable changes
- deferred revenue changes
The reconciliation explains how accounting profit became—or failed to become—cash.
Worked example
Assume:
- net income: $500 million
- noncash depreciation and stock compensation: +$180 million
- receivables increase: -$120 million
- inventory increase: -$90 million
- payables increase: +$40 million
- other operating adjustments: -$80 million
Simplified OCF:
$430 million
Earnings exceeded operating cash generation because working capital absorbed cash.
Depreciation does not create cash
Depreciation is added back under the indirect method because it reduced net income without using current-period cash.
That does not mean depreciation generates cash.
The asset likely required cash when purchased and may require replacement later.
This matters when operating cash flow is compared with free cash flow.
Receivables can make earnings exceed cash flow
A company can recognize credit revenue before customer payment.
If accounts receivable rises:
- revenue can increase
- profit can increase
- cash may not
The receivable increase generally reduces OCF relative to net income.
Rapid growth can therefore create cash pressure.
Inventory can absorb cash before the sale
Buying or producing inventory often requires cash before the goods are sold.
An inventory increase generally uses operating cash.
The build can be rational before expected demand.
It can be weak if the goods become obsolete or require discounting.
The cash-flow statement exposes the commitment.
Payables can boost OCF temporarily
If accounts payable rises, suppliers have not yet been paid for some recognized purchases or expenses.
Cash remains higher.
That usually improves OCF in the period.
The benefit is higher quality when supplier terms improved structurally and weaker when the company is simply delaying payment.
Deferred revenue can create cash before earnings
Subscription companies often collect customer cash before recognizing all related revenue.
Cash increases.
Deferred revenue or another contract liability also increases.
OCF can therefore exceed net income.
That can be a strong business feature when prepayments are recurring and profitable to fulfill.
OCF can exceed earnings for weak reasons too
Strong operating cash flow can be supported by:
- stretched payables
- inventory liquidation
- unusually early collections
- one-time tax timing
- customer prepayments that will not recur
The cash is real.
Its sustainability is the analytical issue.
Northrop Grumman example
Northrop Grumman reported about $1.969 billion of net earnings for the first six months of 2026, while changes in trade working capital used about $2.522 billion of cash. Net cash used in operating activities was $376 million.[2]
That is a clear example of profitable activity producing negative OCF over a period because working-capital timing dominated.
ScanSource example
ScanSource reported approximately $123.1 million of operating cash flow for fiscal 2026, up from about $112.3 million in fiscal 2025. The company attributed the improvement partly to higher net income and stronger working-capital cash contribution.[3]
The driver matters more than the headline increase.
OCF vs. free cash flow
ROIStreet’s GLS-039 — Free Cash Flow explains the common relationship:
Free cash flow ≈ Operating cash flow − capital expenditures
Operating cash flow does not deduct capital spending.
A company can generate:
$1 billion of OCF
and spend:
$1.2 billion on capex
Simple free cash flow:
-$200 million
Positive OCF did not cover investment needs.
OCF vs. EBITDA
EBITDA is an earnings measure.
OCF is a cash-flow statement measure.
EBITDA does not directly capture:
- receivable collection
- inventory investment
- payable timing
OCF does.
A company can have strong EBITDA and weak OCF when working capital consumes cash.
Stock-based compensation requires judgment
Stock-based compensation is noncash in the current period and can be added back in the OCF reconciliation.
That helps cash flow relative to net income.
But share issuance can dilute shareholders.
The cash statement is correct.
The per-share economics still need analysis.
Tax timing can create large swings
Cash taxes can differ from tax expense because of:
- deferred taxes
- estimated-payment timing
- refunds
- settlements
- credits
OCF can move materially even when operating performance is stable.
A multi-year view reduces the risk of overreacting to one tax period.
One quarter can be noisy
Quarterly OCF can swing because of:
- bonus payments
- tax dates
- customer billing
- seasonal inventory
- supplier payment timing
For many businesses, trailing twelve months and multi-year trends are more useful than one quarter.
Example
A company reports $500 million of net income, adds back $180 million of noncash items and uses $250 million of cash in working capital. Simplified operating cash flow is $430 million.
Professional note
A useful OCF review asks:
- Earnings: How much cash came from recurring profit?
- Noncash items: Which adjustments are large or recurring?
- Receivables: Are customers paying on time?
- Inventory: Is cash being tied up in stock?
- Payables: Are supplier terms sustainable?
- Capex: How much cash remains after necessary investment?
Operating cash flow is most useful when it shows whether reported business activity actually turns into cash without relying on temporary working-capital timing.

- Absolute Priority Rule
The Absolute Priority Rule is the Chapter 11 principle reflected in Bankruptcy Code Section 1129(b) that, in specified cramdown circumstances, prevents a junior class from receiving or retaining property on account of its junior claim or interest when a senior dissenting class is not paid in full.
- Accounts Payable
**Accounts payable** are amounts owed to suppliers for goods or services a company has received but has not yet paid for. They are generally current liabilities and can function as a form of short-term operating financing because the company receives value before cash leaves.
- Accounts Receivable
**Accounts receivable** are amounts owed by customers for goods or services a company has already provided but has not yet collected in cash. Companies usually report receivables net of allowances for expected credit losses, returns, discounts or other adjustments.
- Accrued Expenses
Accrued expenses are costs a company has incurred but has not yet paid in cash. They are generally recorded as liabilities so expense recognition follows the economic period rather than the payment date.
- Accumulated Other Comprehensive Income (AOCI)
Accumulated other comprehensive income is the cumulative equity balance of specified gains and losses recognized in other comprehensive income rather than ordinary net income.
- Add-On Acquisition
An add-on acquisition is a company purchased by an existing portfolio company—often a platform company—to expand scale, geography, products, customers, capabilities or market share.
