What you miss reading one statement alone
Open any annual report and you will find three core statements. They answer different questions. The income statement shows what the company earned over a period; the balance sheet shows what it owns and owes at a single date; the cash flow statement shows where cash actually came from and where it went.
Read only one and it is easy to miss a company whose profits rise while its cash shrinks, or one whose large asset base is mostly hard to collect. This guide covers what to look at first in each statement and how to connect the three to test whether reported profit is turning into cash.
Income statement: find the core business
The income statement runs from revenue through cost of sales, gross profit, operating expenses, operating income, non-operating items, and taxes down to net income. The performance of the core business shows up mostly above the operating income line. If revenue grows but gross margin falls because of discounting or rising costs, the quality of that growth has weakened.
Items below operating income often have little to do with the core business: gains on selling investments, currency gains and losses, impairments. These can swing net income sharply, so when profit jumps or collapses, separate operating income from non-operating items before drawing conclusions.
Balance sheet: resources and resilience
The balance sheet rests on one equation: assets equal liabilities plus shareholders' equity. The SEC's Beginners' Guide to Financial Statements describes it in exactly those terms, as what a company owns, what it owes, and what is left for shareholders. Look beyond cash and debt to the mix of assets and the timing of obligations.
Receivables growing faster than sales, or inventory piling up, can mean profit has been booked but cash has not arrived. Current liabilities well above cash suggest the company may need to refinance or raise money. A large share of goodwill and intangibles raises the question of future impairments.
Cash flow statement: test profit against cash
The cash flow statement has three sections, and IAS 7 requires cash flows to be classified as operating, investing, or financing. Operating cash flow shows whether the business generates cash; investing shows spending on equipment and acquisitions and proceeds from asset sales; financing shows borrowing, repayments, dividends, and buybacks.
Operating cash flow typically starts from net income, adds back non-cash charges such as depreciation, and adjusts for changes in working capital such as receivables and inventory. Comparing it with net income shows how much of the reported profit became cash in the period.
Linking the three: a three-year example
The hypothetical company below grew revenue and profit every year. On the income statement alone it looks healthy; the other two statements tell a different story.
| Item | Year 1 | Year 2 | Year 3 |
|---|---|---|---|
| Revenue | 1,000 | 1,200 | 1,350 |
| Net income | 80 | 100 | 115 |
| Operating cash flow | 90 | 70 | 40 |
| Accounts receivable (year-end) | 150 | 260 | 400 |
| Cash conversion (OCF ÷ net income) | 1.13 | 0.70 | 0.35 |
Profit rose while operating cash flow fell and receivables nearly tripled, a sign that sales may not be turning into collected cash.
Questions the example raises
Revenue grew 35% over three years, but receivables grew about 2.7 times. The company may have offered customers longer payment terms to win sales, or a large customer may be paying late. The receivables note, with its aging schedule and allowance for doubtful accounts, is the next place to look.
Cash conversion falling from 1.13 to 0.35 means each dollar of profit brought in far less cash. If financing cash flow shows rising borrowing over the same period, the company may be using debt to cover the cash its operations are not producing.
Reading the statements in a 10-K
Investor.gov's guide to the 10-K points readers to the financial statements and the MD&A, where management explains the year's results. A practical order for connecting the three statements:
- On the income statement, calculate revenue, gross profit, and operating income trends and margins for three to five years.
- Read the notes on other income and expense to see whether non-recurring items affected net income.
- On the balance sheet, compare growth in receivables and inventory with growth in revenue.
- Put operating cash flow next to net income for each year and calculate the cash conversion ratio.
- In investing and financing cash flows, total capital spending, acquisitions, net borrowing, dividends, and buybacks to see where the cash went.
What the numbers cannot tell you
Financial statements describe the past and depend on accounting rules and management estimates, such as loss allowances, depreciation lives, and impairment judgments. Companies in the same industry may apply different policies, so the accounting-policy note matters when comparing them.
The company in the table is hypothetical. Real analysis should use the latest annual and quarterly reports, note their dates, and focus on multi-year trends and the reasons behind them rather than any single year.
