Lesson 1 of 45

Financial statements are the report card of a business. Public companies publish them every quarter and every year, showing how much they sold, what they spent, what they own, what they owe and how much cash came in and went out. Traders who understand them can judge whether a stock's price makes sense, anticipate how results might surprise the market and avoid companies with hidden problems. This lesson gives the map; the following lessons go into each statement in detail.

The three core statements#

Statement	Shows	Period	Lesson
Income statement	Revenue, costs and profit	Over a period (quarter or year)	Income Statement
Balance sheet	Assets, liabilities and equity	At a point in time	Balance Sheet
Cash flow statement	Cash in and out from operations, investing and financing	Over a period	Cash Flow Statement

How they connect#

Net income from the income statement flows into retained earnings on the balance sheet and is the starting point of the cash flow statement.
Changes in balance sheet items, such as inventory and receivables, explain why cash flow differs from profit.
Cash at the end of the cash flow statement equals cash on the balance sheet.

Where to find them#

Source	Content
Form 10 K (US)	Annual report with audited statements and detailed notes
Form 10 Q (US)	Quarterly report, reviewed but not audited
Form 8 K (US)	Material events, including earnings releases
Earnings press release	Headline numbers and often non GAAP measures
Annual reports outside the US	Under IFRS or local standards

US filings are free on the SEC's EDGAR system. See Earnings Season Explained.

GAAP, IFRS and non GAAP#

GAAP (US Generally Accepted Accounting Principles) and IFRS (International Financial Reporting Standards) are the official rule books.
Non GAAP or adjusted figures, such as adjusted EBITDA or adjusted EPS, exclude items management considers unusual. They can be helpful, but they can also flatter results. Always compare them with official numbers. See Earnings Quality and Cash Conversion.

What traders check first#

Revenue growth versus expectations. See Revenue and Gross Profit.
Margins: gross, operating and net. See Revenue Growth and Margin Analysis.
Earnings per share versus consensus. See Net Income and EPS.
Cash flow versus profit. See Free Cash Flow.
Debt and liquidity on the balance sheet.
Guidance for future periods. See Guidance and Earnings Revisions.

The notes matter#

The notes to the financial statements explain accounting policies, debt terms, leases, lawsuits, segment results and one off items. Many red flags, such as aggressive revenue recognition or off balance sheet obligations, appear only in the notes.

Common mistakes#

Reading only headlines or adjusted figures.
Ignoring cash flow and the balance sheet.
Comparing companies with different accounting without adjustment.
Looking at one quarter instead of trends.

Frequently asked questions#

What are the three main financial statements?#

The income statement, the balance sheet and the cash flow statement.

In its annual and quarterly reports, such as the 10 K and 10 Q filed with the SEC on EDGAR for US companies, and on its investor relations website.

Why is cash flow different from net income?#

Because accounting profit includes non cash items and timing differences, such as unpaid invoices, inventory build ups and depreciation.
