Check what the business does and the risks it faces, then compare its results, cash flow, financial position, management’s explanations, audit disclosures and adjusted figures across comparable periods. Those checks help you understand performance; they do not establish that the stock is attractively priced.
Start with the right filings
For a U.S. public company, the Form 10-K is the annual filing. It includes audited financial statements, business information, risk factors and management discussion. The Form 10-Q is a quarterly update with unaudited financial statements and updated risk disclosures.

An earnings release or Form 8-K may summarize results before the complete 10-Q or 10-K is filed. Treat the summary as a starting point, then read the full filing and check for material later disclosures. You can find public-company filings through the SEC’s EDGAR search tools.

This guide focuses on U.S. disclosure forms. Foreign issuers may file different SEC forms, and companies outside the SEC reporting system may follow other disclosure regimes.

Understand the business and its risks
Read the 10-K’s Business and Risk Factors sections before treating a growth rate or profit figure as self-explanatory. Identify what the company sells, where it operates and what competitive, regulatory or company-specific pressures could affect its results. The SEC says companies generally list risk factors in order of importance, but the disclosures can also cover broad economic, industry and geographic risks.
Use those disclosures to put the numbers in context: a change in sales may mean something different for a company exposed to a particular market, regulation or operating risk than for a business with a different model.
Compare performance across like periods
Look at revenue, expenses, operating income, net income and earnings per share. Note whether each figure covers a quarter, a year-to-date interval or a full fiscal year. Compare the current period with the same period in the prior year where possible, and read the filing’s explanation of material changes.

Do not assume two periods are directly comparable. Seasonality, acquisitions, asset sales and other events can change the picture. When comparing companies, also account for differences in business models, industry conditions, accounting policies and share counts.
Read the three financial statements together
The statements answer different questions: the income statement reports performance over a period, the balance sheet shows financial position at a reporting date, and the cash flow statement tracks cash received and used over a period. The SEC’s Beginners’ Guide to Financial Statements puts the distinction plainly: “While an income statement can tell you whether a company made a profit, a cash flow statement can tell you whether the company generated cash.”
Check whether earnings translate into operating cash
Compare net income with cash from operating activities. If they diverge, inspect the cash flow statement for significant adjustments and working-capital movements rather than assuming the difference has one particular cause. Also review capital spending and financing cash flows. Profit and cash generation are related, but they are not interchangeable measures.
Assess liquidity, debt and other obligations
Use the balance sheet to examine assets, liabilities and shareholders’ equity at the reporting date. Consider liquidity and changes in debt, as well as other material obligations. Read the notes and current reports for disclosed debt, lease, contingent or off-balance-sheet commitments.
Ratios can help compare a company with its own history or relevant peers, but they are not universal pass-or-fail tests. The SEC notes that desirable ratios vary by industry. A ratio’s usefulness depends on the business and the comparison being made.
Read management’s discussion and the notes
Management’s Discussion and Analysis (MD&A) explains management’s view of results, liquidity, capital resources, known trends or uncertainties, and critical accounting estimates. Check whether the explanation fits the reported figures, and look for changes in estimates or accounting policies that could affect comparisons.
Rank #4
Financial-statement notes provide important detail that headline figures may leave out. Pay attention to disclosures about taxes, pensions and stock-based compensation, among other matters relevant to the company, and consider how judgment-heavy accounting details may affect interpretation.

Read the independent auditor’s opinion and disclosures about material weaknesses in internal control. These are relevant to how you interpret reported results; do not treat a headline number as a complete account of the reporting context.

If the company highlights adjusted or other non-GAAP measures, compare them with the closest GAAP figures and inspect the reconciliation and excluded items. An adjusted figure is not automatically more informative because it appears prominently in a release.
Best Value
Keep performance separate from valuation
Strong reported results do not by themselves show that a stock is attractively priced. First understand the company’s performance, financial condition and risks; assessing what investors are paying for the shares requires separate valuation analysis and context. The filings support research and interpretation, not a prediction of returns or a personalized buy recommendation.
The SEC sets disclosure requirements and may review filings for compliance, but that process is not a guarantee that every filing is accurate. As Investor.gov notes, “The SEC does not vouch for the accuracy of a 10-K or 10-Q.”
