Lesson 1 of 7 · 5 min read · Intermediate · Free · Last reviewed October 2026

The short version

Financial statements show where a company's money came from, where it went, and where it is now. The income statement shows whether the company made a profit over a period. The balance sheet shows what it owns and owes at one moment, and always balances: assets equal liabilities plus shareholders' equity. The cash flow statement shows the cash that came in and went out, split into operating, investing, and financing activities. Each tells part of the story; together they show the whole business.

By the end of this lesson, you'll be able to

  • Name the three main financial statements and the question each answers
  • Explain the difference between a statement that covers a period and one that shows a single moment
  • Use the balance sheet equation

Why this matters

Every number in the last module, from STU Corp's margins to the cash it spent on equipment, comes from its financial statements. They're a company's official scorecard, prepared under accounting rules and, for the annual report, checked by an outside auditor. Learning to read them is the single most useful skill for understanding a business. This module uses STU Corp's statements throughout.

Three statements, three questions

The SEC's guide to financial statements describes them as showing where a company's money came from, where it went, and where it is now. It lists four main statements: the balance sheet, the income statement, the cash flow statement, and the statement of shareholders' equity, which tracks changes in the owners' stake.1 This module focuses on the first three.

What each statement answers
StatementThe questionCovers
Did the company make a profit?A period, such as a year or a quarter
What does it own, and what does it owe?A single moment, such as the last day of the year
Where did the cash come from, and where did it go?A period

A helpful comparison is your own finances. Your income statement would be this year's pay minus this year's spending. Your balance sheet would list what you own today, like savings and a car, and what you owe, like a car loan. Your cash flow statement would be your bank account's record of money in and money out. Two of them are like a video of a period; the balance sheet is a photo of one moment.

The balance sheet always balances

Everything a company owns, its assets, was paid for either with money it owes to others, its , or with the owners' money, called . So the two sides must always be equal:1

Assets = Liabilities + Shareholders' equity

Worked example: STU Corp balances
$ millionsEnd of this yearEnd of last year
Total assets335289
Total liabilities145148
Shareholders' equity190141
Liabilities plus equity145 + 190 = 335148 + 141 = 289

Rearranged, the equation says shareholders' equity is what's left after subtracting everything owed from everything owned: $335 million − $145 million = $190 million. That's the owners' stake, measured by the accounting rules.

Where to find them

A company's annual report on Form 10-K includes its audited financial statements: the income statement, which is sometimes called the statement of earnings or the statement of operations, the balance sheet, the statement of cash flows, and the statement of stockholders' equity.2 The notes that follow the statements explain the accounting choices behind the numbers, and the SEC's guide stresses how important it is to read them.1

Key takeaways

  • The income statement shows profit over a period. The balance sheet shows what's owned and owed at one moment. The cash flow statement shows cash in and out over a period.
  • Assets always equal liabilities plus shareholders' equity.
  • STU Corp had $335 million of assets, $145 million of liabilities, and $190 million of equity at the end of this year.
  • The audited statements are in the annual report on Form 10-K, followed by notes worth reading.

Check your understanding

A company has $500 million of assets and $320 million of liabilities. What is its shareholders' equity?
