A practical first pass through a company annual report

Start with the filing and period

Investor.gov describes annual Form 10-K and quarterly Form 10-Q filings as important sources for researching U.S. reporting companies. They contain structured sections on the business, risks, management discussion and financial statements. Companies outside the United States may use other reporting forms and accounting frameworks, so first identify the relevant reporting jurisdiction.

Confirm the company’s legal name, reporting period, filing date and currency. Distinguish an annual report’s audited statements from a press release or an investor presentation. Keep a short document log so you can trace every important number to the period and page where it appeared.

Ask three questions before calculating ratios

First, how does the business earn revenue? Write a paragraph in your own words describing its customers, products, pricing model and major operating segments. If you cannot explain the model without copying management’s language, flag the unclear points for further research.

Second, what could interrupt that model? Read the risk section with the business description beside it. Look for specific dependencies such as a major customer, refinancing requirement, input supply or regulatory permission. A long list of risks should not be mistaken for a ranking of their probability.

Third, how do earnings relate to cash? Locate the income statement, balance sheet and cash flow statement. Compare like periods and read the relevant notes before treating a difference as good or bad. An acquisition, disposal, accounting change or unusual item can make a simple comparison incomplete.

Create an evidence table

Use four columns: claim, source location, supporting figure and unresolved question. For a hypothetical statement that sales increased, record whether the reported change came from volume, prices, acquisitions or currency translation if the filing explains it. Do not infer a cause simply because two figures moved together.

When management presents adjusted results, find the reconciliation to the accounting measure and examine what was excluded. Keep the company’s definition attached to the number. Finish with a balanced research note that describes both strengths and uncertainties. Reading a filing can improve understanding, but it does not establish a fair price or remove the possibility of losing money on the shares.
