Reading Financial Statements

Three statements describe a business: income, balance sheet and cash flow.

The short answer

A company's three core financial statements — the income statement, the balance sheet and the cash flow statement — together show what a business earned, what it owns and owes, and how much actual cash moved through it. Reading all three, rather than just the headline profit figure, is what turns a company's story into evidence.

What you'll learn

  • Identify the purpose of the income statement, balance sheet and cash flow statement
  • Distinguish revenue, operating income, net income and free cash flow
  • Explain why free cash flow can differ significantly from reported profit
  • Use the free cash flow waterfall to see how operating cash becomes free cash flow

Optional supplemental lesson. It doesn't count toward the certificate.

Income statement

Covers a period of time. Revenue at the top, costs subtracted along the way, profit at the bottom. Key lines: revenue, gross profit, operating income, net income and earnings per share.

Revenue is sales the company has recognised under accounting rules — not cash collected. Hypothetical example: a company delivers $100 of goods on credit and has collected $0 by year end. The income statement shows $100 of revenue; the balance sheet shows a $100 accounts receivable (money owed by the customer); the cash flow statement shows $0 of cash from that sale.

Margins matter more than absolute numbers: gross margin shows pricing power, operating margin shows operational discipline.

Balance sheet

A snapshot at a single date. Assets equal liabilities plus equity. Liabilities are obligations the company owes — not only borrowed money. Debt is one kind (a loan to repay with interest); accounts payable is another (bills owed to suppliers for goods already received); others include taxes owed, deferred revenue and lease obligations.

The equation always balances, so it proves nothing about health. Positive equity does not prove a company can pay its bills on time (liquidity) or meet its obligations over time (solvency). Look at cash, the timing of debt and whether short-term obligations are comfortably covered.

Debt is not automatically bad. Debt that requires perfect conditions to service is.

Cash flow statement

Tracks actual cash moving in and out in three sections: operating activities (cash from running the business), investing activities (buying or selling equipment, businesses and investments) and financing activities (borrowing, repaying debt, issuing or buying back shares, paying dividends). Most companies use the indirect method, so the operating section often begins with net income and then adjusts for non-cash items and changes in working capital.

Free cash flow is commonly defined as operating cash flow minus capital expenditure. It is not a standardised GAAP line — companies and data providers define it differently — and it is not cash guaranteed to be available for shareholders after every obligation, such as debt repayments.

Profit involves accounting judgement. Cash is harder to manufacture, which is why experienced investors read this statement first.

Revenue, earnings and cash flow are three different questions

Revenue answers: how much the company earned from delivering goods or services in the period, recognised when it satisfies its obligations to customers — which is not the same as the cash customers paid in that period (payments can arrive earlier, as deferred revenue, or later, as receivables). Earnings (net income) answers: what was left after every cost, including non-cash accounting items like depreciation. Free cash flow answers: how much actual cash was generated after the spending needed to keep the business running.

A company can grow revenue while earnings shrink, if costs are rising faster than sales. It can also report positive earnings while free cash flow is negative, if profit relies on non-cash items or if capital spending is heavy. None of these patterns is automatically bad, but each demands an explanation before you move on.

− Operating costsCost of goods sold, overhead, R&D

Leaves operating income

− Taxes and interestObligations before shareholders are paid

Leaves net income (earnings)

Operating cash flowCash generated by running the business

Indirect method: starts from net income, adjusts for non-cash items and working capital

− Capital expenditureSpending needed to maintain and grow the business
= Free cash flowA common measure of cash that may fund dividends, buybacks, debt paydown or reinvestment

Not a GAAP line; debt repayments and other obligations may still be due

A simplified path. Free cash flow here uses the common definition (operating cash flow − capital expenditure); it is not a standardised accounting line.

Educational example

Amazon.com, Inc. (AMZN)

Amazon is a useful company to study for the gap between reported earnings and cash flow, given its history of heavy capital expenditure on logistics and infrastructure. Reading its cash flow statement in its 10-K filings, alongside the income statement, shows how capital-intensive growth can affect free cash flow differently than it affects reported profit.

Why this matters

Statements are where a story stops being a story and becomes evidence.

How this connects to Intelligent Accumulation

Checking whether reported profit is backed by actual cash flow is a core part of buying intelligently, well before valuation or momentum are considered.

Common beginner mistake

Reading net income only, and never checking whether cash flow supports it.

Key takeaways

  • The income statement, balance sheet and cash flow statement answer different questions
  • Revenue, earnings and free cash flow can diverge, and each divergence deserves an explanation
  • Free cash flow is commonly defined as operating cash flow minus capital expenditure — a non-GAAP measure
  • Revenue is recognised sales, not necessarily cash collected; liabilities are all obligations, not just debt
  • Margins reveal more than absolute dollar figures when comparing periods
