The three reasons a profitable company burns cash
Name these three and you have answered the question. Explain the timing behind each one and you have answered it well.
1. Receivables. The sale is booked. The customer has not paid. Revenue lands on the income statement in full the moment the work is delivered, and the cash arrives thirty, sixty, ninety days later, or never. A company growing fast on credit terms can post record revenue while its receivables balloon.
2. Inventory. Cash goes out the door before the sale happens. You pay the supplier now and you book the cost of that inventory only when it sells. Between those two events, the money is gone and the income statement shows nothing.
3. Capex. When a company buys equipment, the full purchase price leaves the cash account today. The income statement charges a small slice of it each year as depreciation. So in a heavy build year, the income statement is looking at one year of depreciation while the cash flow statement is looking at the entire bill.
| What happened | What the income statement shows | What the cash account does |
|---|
| Sale made, customer has not paid | Revenue booked in full | Nothing moves yet |
| Inventory bought ahead of a sale | No cost recorded until it sells | Cash leaves now |
| Equipment bought | One year of depreciation | The full purchase price leaves now |
That is how a company is profitable on paper and bleeding in the bank account.
The follow-up: can it go the other way?
Banks love this one and it trips people up. Can you have losses on paper and positive cash flow?
Yes. Two things do it.
Very large depreciation will push a company to a loss while the cash flow is fine, because depreciation is a paper charge and no money left the building when it was recorded. Big write-downs do the same thing, harder. A company that writes down an asset takes the whole hit on the income statement in one quarter and never writes a check for it.
Both charges reduce net income and get added straight back on the cash flow statement. The bottom line goes red. The cash keeps coming in.
Netflix in 2019
Here is the question playing out in public. In 2019 Netflix reported roughly $2 billion of profit and burned more than $3 billion of actual cash in the same year. Same company, same filings, both numbers true.
The reason was content spend. The cash for a show leaves years before the cost of that show works its way through the income statement, so the cash flow statement was carrying a bill the income statement had barely started to recognize. The gap was funded by debt. The model has since matured and free cash flow is strongly positive.
If you want to use this in an interview, pull the 10-K and read the two statements side by side. The mechanism is the point: a large, front-loaded cash commitment that the income statement recognizes over years.
EBITDA gets you close and stops short
People say EBITDA is basically cash flow. It is the closest income statement number to the cash an operation generates, and it is still a different number.
EBITDA ignores capex. It ignores working capital. It ignores interest and taxes. Every one of those is a real claim on real money.
Netflix was EBITDA positive the entire time it was burning cash. If EBITDA were cash flow, that year could not have happened.
When the gap runs for years
A single year of divergence is usually just timing. Years of it is a signal.
In early 2001 Enron was the seventh largest company in America and had reported roughly a billion dollars of profit for the prior year. Bethany McLean, a Fortune reporter and former Goldman Sachs analyst, sat down with the public filings and could not answer one basic question: how does this company actually make money? The profits went up on paper quarter after quarter and never turned into cash in the bank, and debt kept growing. She published a politely titled piece asking whether Enron was overpriced. Nine months later the company filed for one of the largest bankruptcies in American history to that point.
She had no inside information. She had the same three statements anyone could pull.
Earnings up, cash not following, debt growing. When net income and free cash flow diverge for years, something in the model is off. Sometimes it is the accounting. Sometimes it is fraud. The numbers will not tell you which. They will tell you where to dig.
How to say it out loud
Analysis questions are verdict tests. The interviewer is not grading the arithmetic so much as your ability to move between numbers, form a judgment, and say it cleanly.
Something like this:
"Profit and cash run on different clocks. Net income books revenue when it is earned, and cash moves when money actually changes hands. So a profitable company burns cash in three main ways. Receivables, where the sale is on the income statement and the customer has not paid. Inventory, where the cash went out before there was a sale to book it against. And capex, where the full purchase price leaves today and the income statement only charges a slice of it each year as depreciation. It runs the other way too. A company with heavy depreciation or a large write-down can post a loss and still generate positive cash, because neither charge is money leaving the building."
Then stop. If they want the Netflix case or the Enron pattern, they will ask, and you will have it.
This question is one rung of a larger check. The full version puts free cash flow next to net income every time you open a set of financials, and it is the step that catches the businesses everything else on the page says are fine.
