How to Read a Cash Flow Statement in Six Minutes

The cash flow statement is the least-read of the three financial statements and the hardest to manipulate. That combination makes it the most useful place to start.

Operating: is the profit real?

The operating section reconciles reported profit to the cash the business actually generated. The single most useful ratio in financial analysis lives here: cash from operations divided by reported profit, measured over four quarters rather than one.

A business consistently converting most of its profit into operating cash is probably reporting honestly. A business where that ratio drifts down over several quarters is telling you something, and the something is usually receivables or inventory.

Investing: what is it buying?

The investing section separates maintenance capital expenditure from growth capital expenditure, though companies rarely label it that way. The clue is the relationship between capex and capacity or revenue growth. Heavy capex with no corresponding capacity addition is worth a question.

Watch also for acquisitions, and particularly for a pattern of acquisitions that keeps reported growth intact while organic growth stalls underneath.

Financing: who is funding this?

The financing section shows whether growth is funded by the business, by lenders or by shareholders. None of the three is inherently wrong. A pattern of equity issuance to fund operating losses is a different business from one funding expansion with retained earnings, and the financing section is where that difference becomes visible.

The six-minute version

• Compute operating cash flow ÷ net profit across the last four quarters.
• Compare capex to the change in revenue or capacity over the same period.
• Check whether financing inflows are covering an operating shortfall.
• Look at the trend across three years, not the level in one.
