EBITDA can rise while receivables and inventory absorb the cash earned by a business. This worked example connects EBITDA to operating working capital, reconciles the result to operating cash flow and identifies who owns each movement.
An EBITDA working capital bridge shows why higher earnings can coincide with more cash tied up in unpaid invoices and unsold inventory. EBITDA does not deduct the cash absorbed by those operating balances. To understand the difference, compare earnings for the period with the change between its opening and closing working capital balances.
EBITDA is earnings before interest, income taxes, depreciation and amortization. The SEC's non-GAAP guidance defines earnings as GAAP net income for this calculation and distinguishes differently adjusted measures from EBITDA. Keep the earnings definition stable before trying to explain its conversion to cash.
For this bridge, define operating working capital as trade receivables plus inventory minus trade payables. That is a deliberately narrower measure than total current assets minus current liabilities. The full working capital definition and cycle belongs to the existing guide; this calculation isolates the operating balances that move cash in the example.
Operating working capital = Trade receivables + Inventory - Trade payables
Increase in operating working capital = Closing balance - Opening balance
Intermediate cash bridge = EBITDA - Increase in operating working capital
An increase consumes cash; a decrease releases it. That sign is the source of many errors. More receivables mean recognized sales have not yet become collections. More inventory means cash has funded stock not yet expensed through sales. More payables mean suppliers are temporarily funding part of those purchases.
Use a period P&L with its EBITDA reconciliation, opening and closing trial balances, the receivables aging, inventory valuation and payables aging. Keep entity, currency, account mapping and cutoff dates consistent across the exports. Quarter-end balances explain a quarter's cash movement; an annual average balance answers a different question.
The controller should identify operating accruals, prepayments and other balances that belong in the full bridge. Keep cash, debt and capital-expenditure payables outside the simple trade-payables line here. Show those items separately where they enter the final cash flow reconciliation.
Also identify balance changes caused by acquisitions, currency translation, write-offs or other noncash entries. An increase in a receivable acquired with a business is not an unpaid sale generated by the current period's EBITDA. Using the unadjusted balance movement would give the wrong explanation.
Consider a US distributor in the first and second quarters of 2026. All figures are USD. Assume no acquisitions, currency movements, write-offs, inventory impairments or other noncash adjustments beyond depreciation and amortization. Cash interest and cash income taxes equal the respective expenses, and there are no other operating balance movements.
First establish EBITDA from the P&L:
| Earnings component | Q1 (USD) | Q2 (USD) |
|---|---|---|
| Net income | 85,000 | 100,000 |
| Add interest expense | 25,000 | 30,000 |
| Add income tax expense | 30,000 | 35,000 |
| Add depreciation and amortization | 40,000 | 55,000 |
| EBITDA | 180,000 | 220,000 |
EBITDA rises by $40,000: $220,000 - $180,000. The difference between EBITDA and operating income is a separate reconciliation; neither measure tells us when customers paid.
Now calculate the operating balances at each quarter boundary:
| Operating balance | December 31, 2025 (USD) | March 31, 2026 (USD) | June 30, 2026 (USD) |
|---|---|---|---|
| Trade receivables | 360,000 | 420,000 | 540,000 |
| Inventory | 300,000 | 310,000 | 450,000 |
| Trade payables | 220,000 | 250,000 | 290,000 |
| Operating working capital | 440,000 | 480,000 | 700,000 |
June's $700,000 is $540,000 + $450,000 - $290,000. The cash impact follows from differences between adjacent columns:
| Working capital movement | Q1 (USD) | Q2 (USD) |
|---|---|---|
| Increase in receivables: cash used | 60,000 | 120,000 |
| Increase in inventory: cash used | 10,000 | 140,000 |
| Increase in payables: cash provided | 30,000 | 40,000 |
| Net cash absorbed | 40,000 | 220,000 |
Q2 absorbs $120,000 + $140,000 - $40,000 = $220,000. That equals closing working capital of $700,000 minus opening working capital of $480,000. The movement calculation and the balance calculation must agree.
The SEC's financial-statement guide explains that operating cash flow adjusts earnings for noncash items and operating asset and liability movements. Starting from EBITDA also requires restoring the cash interest and income tax outflows that EBITDA excludes.
| Cash bridge | Q1 (USD) | Q2 (USD) |
|---|---|---|
| EBITDA | 180,000 | 220,000 |
| Less cash absorbed by working capital | 40,000 | 220,000 |
| Intermediate amount before interest and taxes | 140,000 | 0 |
| Less cash interest | 25,000 | 30,000 |
| Less cash income taxes | 30,000 | 35,000 |
| Operating cash flow under these assumptions | 85,000 | -65,000 |
Q2 uses $65,000 despite its higher EBITDA. Prove the result by starting from net income instead: $100,000 + $55,000 depreciation and amortization - $220,000 working capital absorption = -$65,000. Q1 checks as $85,000 + $40,000 - $40,000 = $85,000.
In a real company, add the remaining operating adjustments before tying the result to the cash flow statement. Capital expenditures and principal repayments come afterward when assessing total cash needs. For a borrowing review, cash available for debt service has its own definition and should not inherit the intermediate EBITDA bridge without review.
Receivables point to collections and billing. Inventory points to purchasing, sales demand and stock policy. Payables point to purchasing terms and the payment calendar. Assign an owner to each movement and inspect the underlying invoices or stock rows before changing operations.
As a sensitivity, change only June receivables from $540,000 to $500,000, assuming the $40,000 difference was collected in cash. Closing operating working capital becomes $660,000: $500,000 + $450,000 - $290,000. Its increase is $180,000, and operating cash flow becomes $220,000 - $180,000 - $30,000 - $35,000 = -$25,000.
That single collection improvement releases $40,000 without changing EBITDA. It still leaves negative operating cash flow, so collections alone do not resolve the quarter's cash requirement. Use working capital days to inspect time tied up in operations, and working capital turnover for sales generated relative to the balance employed.

A balance-sheet increase in receivables or inventory does not by itself reduce EBITDA. Related expenses can affect earnings, including credit losses and inventory write-downs. Analyze those income-statement charges separately from the cash tied up in the underlying operating balances.
It is an intermediate bridge that still needs reconciliation. Cash interest, cash income taxes and other noncash or operating adjustments may remain. Use the company's statement of cash flows and supporting schedules to establish the complete operating cash flow figure.
Exclude cash when calculating operating working capital for an earnings-to-cash bridge. Also separate borrowing balances and financing items. A broad current-assets-minus-current-liabilities measure serves a different purpose and can obscure the operating movements that explain cash generation.
