A cash flow statement shows how cash moved into and out of a company during a specific period. While the income statement measures profitability using accounting rules, the cash flow statement focuses on actual cash movements.
This distinction matters because a company can report accounting profits without generating the same amount of cash. Likewise, some cash expenditures may reduce cash without immediately appearing as expenses on the income statement.
Studying both earnings and cash flow can therefore provide a more complete picture of a company's financial performance.
1. The Three Sections of the Cash Flow Statement
The cash flow statement is generally divided into three major sections:
- Cash Flow from Operating Activities
- Cash Flow from Investing Activities
- Cash Flow from Financing Activities
Together, these sections explain how the company's cash balance changed during the reporting period.
2. Cash Flow from Operating Activities
Operating cash flow represents cash generated or used by the company's primary business operations.
It can include cash effects associated with customers, suppliers, employees, taxes, and other normal operating activities.
For many established businesses, consistently positive operating cash flow can be an important characteristic to research because it indicates that the underlying operations are producing cash.
However, operating cash flow should be examined over several periods and in relation to other financial information rather than interpreted by itself.
3. Why Net Income and Operating Cash Flow Can Differ
Net income and operating cash flow are related, but they are not the same.
Accounting earnings can include non-cash expenses and revenues or expenses recognized at a different time from the related cash movement.
Depreciation is one example of a non-cash expense. Changes in accounts receivable, inventory, accounts payable, and other working-capital accounts can also cause operating cash flow to differ from net income.
These differences are one reason investors may want to examine cash flow in addition to reported earnings.
4. Depreciation and Amortization
Depreciation and amortization allocate the cost of certain assets over time for accounting purposes.
Because these expenses generally do not represent a current-period cash payment, they are commonly added back when reconciling net income to operating cash flow under the indirect method.
This does not mean depreciation is economically meaningless. Businesses may eventually need to replace property, equipment, technology, or other assets, which can require substantial cash expenditures.
5. Working Capital Changes
Changes in working-capital accounts can significantly affect operating cash flow.
For example, if accounts receivable rises because customers have not yet paid for reported sales, earnings may be recognized before the related cash is collected.
Similarly, increasing inventory can consume cash, while increases in accounts payable can temporarily preserve cash because payments to suppliers have not yet been made.
Examining these changes can help investors better understand the relationship between reported earnings and cash generation.
6. Cash Flow from Investing Activities
Investing cash flow generally shows cash used for or received from investments in long-term assets and other investments.
Common items can include:
- Purchases of property and equipment
- Sales of property and equipment
- Business acquisitions
- Purchases or sales of investments
Negative investing cash flow is not automatically a warning sign. A growing company may be investing heavily in productive assets or expansion.
The purpose and sustainability of those investments deserve consideration.
7. Capital Expenditures
Capital expenditures, often abbreviated as CapEx, are amounts spent to acquire, maintain, or improve long-term assets such as buildings, machinery, equipment, and technology.
Capital expenditures are important when evaluating cash generation because businesses often need to reinvest some of their operating cash flow to maintain or expand their operations.
This leads to another commonly studied measure: free cash flow.
8. Free Cash Flow
A commonly used simplified calculation for free cash flow is:
Free Cash Flow = Operating Cash Flow − Capital Expenditures
Free cash flow attempts to show how much cash remains after accounting for capital expenditures.
Positive free cash flow can give a company financial flexibility to reduce debt, repurchase shares, pay dividends, make acquisitions, invest in growth, or retain cash.
Free cash flow definitions can vary among analysts and data providers, so investors should understand how a particular figure has been calculated before comparing companies.
9. Cash Flow from Financing Activities
Financing cash flow reflects transactions involving the company's financing and capital structure.
Common examples include:
- Issuing or repaying debt
- Issuing shares
- Repurchasing shares
- Paying dividends
Financing cash flow can help show how management is raising capital and returning capital to investors.
A company borrowing substantial amounts of money may show a cash increase even when its operations are not generating sufficient cash. For that reason, the source of changes in cash matters.
10. Dividends and Share Repurchases
Dividends and share repurchases generally require cash.
When evaluating these distributions, investors may want to consider whether the company generates sufficient cash to support them while also meeting debt obligations and reinvesting in the business.
A dividend or repurchase program by itself does not establish that a company is financially strong. Its sustainability depends on the company's broader financial condition and cash-generating ability.
11. Free Cash Flow After Dividends
Another useful research calculation is the amount of free cash flow remaining after dividend payments:
Free Cash Flow After Dividends = Free Cash Flow − Cash Dividends Paid
This can provide additional perspective on whether cash generated by the business is sufficient to cover both capital expenditures and shareholder dividend payments.
A positive figure means cash remained under this calculation after those uses of cash. A negative figure deserves additional investigation but does not, by itself, establish that the dividend is unsustainable.
12. Comparing Earnings with Cash Flow
Over longer periods, investors may want to compare a company's reported earnings with its operating cash flow and free cash flow.
If reported profits are consistently strong while cash generation remains weak, the difference may deserve closer examination.
Possible explanations can include working-capital changes, substantial capital requirements, accounting adjustments, rapid growth, or other company-specific factors.
The purpose is not to assume that a difference is automatically negative, but to understand why the difference exists.
13. Why Several Years Matter
A single year of cash flow can be affected by unusual expenditures, acquisitions, changes in working capital, economic conditions, or other temporary events.
Reviewing several years can help reveal whether operating cash flow and free cash flow are generally consistent, improving, deteriorating, or unusually volatile.
Multi-year analysis can also help investors determine whether dividends, debt repayment, share repurchases, and capital expenditures appear supported by internally generated cash over time.
14. Warning Signs Worth Researching
Cash-flow observations that may deserve additional investigation include:
- Persistent negative operating cash flow
- Reported profits accompanied by persistently weak operating cash flow
- Rapidly increasing accounts receivable relative to the business
- Large recurring cash needs that consistently exceed internally generated cash
- Heavy reliance on borrowing or new share issuance to maintain cash balances
- Dividends or repurchases that substantially exceed available free cash flow over extended periods
None of these observations automatically proves that a company is financially weak. They are signals that may warrant additional research.
How Stock Sage Uses Cash Flow Information
Stock Sage presents cash-flow information as part of the broader company research process.
This information allows users to examine the relationship between reported earnings and the cash generated by the business. It also provides additional context for capital expenditures, dividends, debt, and other uses of cash.
Stock Sage's fundamental qualification begins with its core requirements for earnings history and balance-sheet strength, while cash-flow information provides another layer of research for evaluating a qualifying company.
Cash flow should therefore be considered together with EPS, assets, liabilities, profitability, debt, valuation, and other relevant financial information rather than treated as a stand-alone indicator.
