How to Read a 10-K Annual Report (Without Falling Asleep)

Every US public company must file a 10-K with the SEC each year. It is the single most complete public document about a business, and most people never open one. You do not need to read all 100+ pages - you need a route through it.

Item 1 (Business) tells you in plain words how the company actually makes money, who its customers are, and how competitive the market is. Item 1A (Risk Factors) is the legally mandated list of everything that could go wrong; skim the first three or four, because companies put the risks they care about most at the top.

Item 7 (Management Discussion & Analysis, or MD&A) is the best page in the document: management explains the year in its own words, reconciling results to the numbers. Compare what executives emphasise this year with what they emphasised last year - shifts in emphasis are signals.

Items 8 (Financial Statements) and the notes that follow are the raw data. On this site we extract those statements for you, but the notes contain the judgements: revenue recognition policy, segment breakdowns, and stock-compensation detail. Finally, Item 9A (Controls & Procedures) - if a company ever reports a material weakness there, treat every other number with caution.

A good working routine: Item 1 for five minutes, Item 1A for five, MD&A for ten, then the statements themselves. Twenty minutes gives you more real insight about a business than a month of news headlines.
