What should you read in a 10-K?
Use the business description to understand how the company earns money, the risk factors to identify vulnerabilities, and management’s discussion and analysis to examine the results. Read the financial statements and footnotes together.
Our reading worksheet starts with three questions: who pays the company, what must it spend to keep operating, and which assumption would most damage the investment case if it failed? Record a page or section reference beside each answer so you can revisit the evidence.

What does a 10-Q add?
A 10-Q updates the financial picture during the fiscal year, and its statements are unaudited. There is no separate fourth-quarter 10-Q requirement; the annual reporting cycle closes with the 10-K.
Compare a quarter with the same quarter a year earlier before interpreting a sequential change. For a seasonal business, the holiday quarter and the following quarter answer different operating questions.

How do you avoid mixing quarterly and year-to-date figures?
Consider a hypothetical company reporting USD 240 million of operating cash flow for nine months and USD 150 million for six months. Third-quarter operating cash flow is USD 90 million: 240 minus 150, assuming the figures use the same accounting basis and scope.
Do not compare the nine-month cash-flow figure directly with three-month net income. Label every figure with the metric, units, fiscal period, and whether it is a quarter or a cumulative amount.
| Item | Amount | Period |
|---|---|---|
| Operating cash flow | USD 240 million | Nine months |
| Operating cash flow | USD 150 million | Six months |
| Derived third quarter | USD 90 million | Three months |
Where can you find company filings?
Search SEC EDGAR for the company and filter by filing type. Check the issuer and fiscal period before opening a 10-K or 10-Q; similarly named businesses can be different legal entities.
Keep a short comparison log: the prior assumption, the new disclosure, and the question it raises. A change in language is a reason to investigate, not proof that management is hiding a problem.

Limitations to keep in view
Audited statements do not guarantee a good investment or eliminate estimation risk. This guide addresses domestic reporting-company forms; other issuers can use different SEC forms.
The arithmetic example assumes comparable figures and no restatement. If earlier periods were revised, use the revised numbers and document the change.
