What's the difference between the income statement, balance sheet, and cash flow statement?

Simply put, these three statements are like three different camera lenses for a company. The income statement and cash flow statement shoot a 'video'—they record the company's performance over a period (like a quarter or a year). The balance sheet takes a 'photo'—a snapshot of what the company owns and owes at a specific moment (e.g., December 31).^[1]

The income statement tells you how much 'accounting profit' the company earned. But note: this profit is calculated using accrual accounting, not actual cash received. The cash flow statement then 'converts' the accrual numbers back into real cash flows. The balance sheet shows the company's financial position: assets (cash, equipment, inventory, etc.), liabilities (money owed), and shareholders' equity (what truly belongs to shareholders).^[1][2]

No single statement tells the whole story—you must combine all three. To dive deeper into key financial indicators, check out our other article: How to Read US Stock Earnings Reports? A Beginner's Guide to EPS, Consensus Estimates, and Guidance.

Why is net profit positive but operating cash flow negative?

This is one of the most common misunderstandings. The income statement uses accrual accounting: as soon as the company sells goods and issues an invoice, it recognizes revenue—even if the customer hasn't paid yet. Similarly, expenses are recognized when incurred, even if not yet paid. So net profit may look good, but actual cash may not have arrived.^[8]

For example: A company sells 1 million worth of products this quarter, but the customer will pay next quarter. The income statement records 1 million in revenue, and after deducting costs, there might be 200,000 in net profit. But on the cash flow statement, there's no cash inflow from that sale. Meanwhile, the company may have paid cash to buy raw materials, resulting in negative operating cash flow. This is the classic 'paper profit, cash drought' scenario.^[8]

The first section of the cash flow statement (operating activities) typically reconciles net profit back to actual cash—for example, adding back depreciation (a non-cash expense) and subtracting the increase in accounts receivable (money customers owe). This lets you see how much cash actually came in.^[8]

What do 'current' and 'non-current' mean on the balance sheet?

The balance sheet divides assets and liabilities into two categories: current and non-current. 'Current' means expected to be converted to cash or paid within 12 months. For example, cash, accounts receivable (money customers owe), and inventory are current assets. Non-current (long-term) assets are those with a useful life of more than one year, such as factories, equipment, patents, and goodwill.^[3]

Liabilities work the same way: current liabilities are due within one year, like accounts payable (money owed to suppliers) and short-term loans. Non-current liabilities have repayment periods longer than one year, such as long-term bonds. By comparing current assets to current liabilities, you can quickly assess a company's short-term solvency.^[3]

Additionally, assets are divided into tangible assets (physical items like cash and equipment) and intangible assets (non-physical but valuable items like trademarks, patents, and goodwill). Shareholders' equity is the residual after subtracting total liabilities from total assets—it represents the value truly owned by shareholders.^[13]

What is EPS (Earnings Per Share)? Why are basic EPS and diluted EPS different?

EPS stands for earnings per share. It equals net profit divided by the number of outstanding common shares, representing how much profit each share gets. It's one of the most commonly watched profitability metrics.^[5]

Basic EPS only counts common shares already issued. Diluted EPS assumes all securities that could be converted into common shares (like convertible bonds or stock options) are converted, so the denominator is larger. Diluted EPS is usually lower than or equal to basic EPS.^[5]

For example, if a company has 1 million in net profit and 1 million shares outstanding, basic EPS is 1 yuan. But if there are also 100,000 options that could be exercised, diluted EPS is 1 million yuan / 1.1 million ≈ 0.91 yuan. Diluted EPS is more conservative and reflects potential dilution risk.^[5]

What do the three sections of the cash flow statement represent?

The cash flow statement divides cash inflows and outflows into three categories: operating, investing, and financing activities.^[7]

Operating cash flow: Comes from the company's core business, such as cash received from selling goods and cash paid to suppliers and employees. This is the most important part because, in the long run, a company must generate cash from operations to survive.^[7]

Investing cash flow: Includes buying or selling long-term assets (like equipment or real estate) and making or recovering investments. For example, cash spent building a new factory is recorded here.^[7]

Financing cash flow: Relates to raising capital—like cash received from issuing stocks or bonds, and cash paid for debt repayment or dividends. This section shows how the company raises and distributes funds.^[7]

The sum of these three sections is the net change in cash. Add the beginning cash balance, and you get the ending cash balance.^[6]

A company's reported Non-GAAP net profit and GAAP net profit differ a lot—which one should I trust?

GAAP net profit is prepared according to U.S. Generally Accepted Accounting Principles. It's standardized and comparable. Non-GAAP (adjusted) net profit is a number the company calculates by excluding certain 'non-recurring' items (like restructuring costs or stock-based compensation). It's usually higher than GAAP net profit.^[10]

SEC Regulation G requires that when a company discloses a Non-GAAP metric, it must also show the most directly comparable GAAP metric and provide a quantitative reconciliation between the two. Companies can't just show the prettier number.^[10]

It's recommended to start with GAAP net profit as your baseline, then use Non-GAAP as a supplement. If the difference is large, carefully examine which items the company adjusted and judge whether those adjustments are reasonable. Some companies may use adjustments to window-dress their performance, so don't rely solely on the adjusted number.^[10]

Where can ordinary investors find the official three financial statements of US-listed companies for free?

The most authoritative source is the SEC's EDGAR system. All US-listed companies must submit their financial reports through EDGAR, including 10-K (annual report) and 10-Q (quarterly report). The 10-K is an audited, complete annual financial statement—the most authoritative primary source for researching a company's fundamentals.^[11][12]

You can search for any company's original filings since 1996 for free on the SEC's EDGAR full-text search system at https://www.sec.gov/edgar/search/. It's completely free, no need to rely on second-hand summaries.^[12]

Additionally, the 'Investor Relations' page on a company's website usually provides PDFs of its financial reports, but EDGAR is the most original and reliable source.
