Before buying a stock, read the company’s latest annual and quarterly filings—not just its earnings headline. Check what the business does and what could threaten it, compare results with prior periods, see whether reported profit is backed by operating cash, assess debt and other obligations, and read management’s explanations, the notes, and the auditor’s opinion. Strong results alone do not establish that a stock is attractively priced.
Start with the latest filings, not just the earnings release
For a U.S. public company that reports to the SEC, the Form 10-K is its annual report, with business information, risk factors, management discussion, and audited financial statements. The Form 10-Q provides a quarterly update, including unaudited financial statements and updated risk disclosures. An earnings release or Form 8-K can summarize results before the full 10-K or 10-Q is available, so use it as a starting point rather than a substitute for the filing.
Find public-company filings through the SEC’s EDGAR search. Check the filing date and reporting period: a company’s fiscal year may not match the calendar year, and a report may cover a quarter, year-to-date interval, or full fiscal year.
Understand the business and its risks
Begin with the 10-K’s Business and Risk Factors sections. Establish what the company sells, where it operates, and which customers, suppliers, markets, or regulations matter to its results. Then consider what might impede growth or disrupt operations, including competition, regulatory changes, geographic exposure, or company-specific problems.

Risk factors are generally presented in order of importance, but they can include broad economic and industry risks as well as risks specific to the company. Treat the list as a guide to what the company discloses, not as a complete forecast of what will happen. Investor.gov explains the sections in its 10-K guide.
Compare results across periods on a like-for-like basis
Review revenue, expenses, operating income, net income, and earnings per share over multiple periods. Compare the same quarter with the corresponding quarter in prior years where possible; comparing a seasonal quarter with a different part of the year can give a misleading impression. Note whether the figures are quarterly, year-to-date, or annual, and read the company’s explanation for material changes.
Look beyond whether a number rose or fell. Ask what drove the change: more sales, a different mix of products or services, higher costs, a one-time event, or a change in the number of shares. Acquisitions, asset sales, and other events can make periods less comparable; the filing’s discussion and notes may explain their effects.
Rank #2
- Ideal for Gifting
- Ideal for a bookworm
- Comes with Proper Binding
- Revenue and its drivers: Is growth tied to the company’s ordinary business, or does the filing describe unusual events or changes in the business?
- Operating costs and margins: Are costs changing alongside sales, and does management explain material shifts in operating results?
- Net income and earnings per share: Check both the total profit and the per-share figure, while noting changes in share count and any unusual items disclosed.
- Comparability: Check for seasonality, acquisitions, asset sales, accounting changes, or other factors that make the periods different.
Use the three financial statements for different questions
The statements are related, but they do not measure the same thing. The SEC’s Beginners’ Guide to Financial Statements describes the income statement as a record of results over a period, the balance sheet as a snapshot of financial position on a date, and the cash flow statement as a record of cash movements over a period.
| Statement | What it shows | What to examine |
|---|---|---|
| Income statement | Revenue, expenses, and profit or loss over a reporting period | Revenue, operating income, net income, earnings per share, and changes from comparable periods |
| Balance sheet | Assets, liabilities, and shareholders’ equity at the reporting date | Liquidity, debt, other obligations, and how the company’s financial position has changed |
| Cash flow statement | Cash received and used during a reporting period | Cash from operating activities, working-capital movements, capital spending, and financing cash flows |
Check whether accounting profit turns into operating cash
Compare net income with cash from operating activities. Profit and cash generation answer different questions: a company can report earnings while collecting cash more slowly, carrying more inventory, or using cash for other operating needs. The SEC guide 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.”
Read the cash flow statement’s adjustments rather than treating the gap between net income and operating cash as self-explanatory. Look for working-capital movements and other significant changes, then consider capital spending and financing cash flows to understand how cash is being used and obtained. A single period may not settle whether cash generation is sustainable, so compare periods and use the company’s explanations.
Assess liquidity, debt, and other obligations
Use the balance sheet to see what the company owns and owes at the reporting date, and how much shareholders’ equity it reports. Consider whether available resources appear sufficient in context to meet obligations, and whether debt or other commitments have changed. The financial-statement notes and current reports may disclose material debt, lease commitments, contingencies, or off-balance-sheet arrangements.
Ratios can help organize comparisons, but there is no universal pass/fail threshold established here. The SEC notes that desirable ratios vary by industry. A debt-to-equity ratio, for example, relates debt to shareholders’ equity; its meaning depends on the company’s business and the context in which it operates. Compare like businesses and periods, and consult the underlying figures and disclosures rather than relying on a ratio alone.

Management’s Discussion and Analysis (MD&A) gives management’s account of results, liquidity, capital resources, known trends or uncertainties, and critical accounting estimates. Compare that explanation with the statements: does it account for the significant changes, and does it address risks or uncertainties that could affect future results?
The notes provide detail behind reported totals and accounting choices. Pay attention to disclosures about accounting policies and estimates, taxes, pensions, and stock-based compensation when they affect comparisons or interpretation. A headline figure may be hard to understand without the assumptions and explanations behind it. Investor.gov’s guide to the 10-K and the SEC’s financial-statement guide describe where these disclosures fit.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.Review the audit opinion, controls, and adjusted results
Read the independent auditor’s opinion and check whether the filing discloses material weaknesses in internal control. These disclosures matter when judging how much confidence to place in reported figures and processes; do not treat the presence of an audit as a guarantee that every number is accurate. The SEC sets disclosure requirements and may review filings for compliance, but it does not vouch for the accuracy of a 10-K or 10-Q, as Investor.gov cautions in its filing guide.
If management highlights adjusted or other non-GAAP measures, find the closest GAAP figure and read the reconciliation. Examine which items are excluded and whether those exclusions affect the comparison you are making. An adjusted measure is not automatically more informative simply because the company emphasizes it.

Compare companies and periods carefully
When comparing periods or businesses, align the details that can change the meaning of a number. A ratio or margin that helps explain one business model may be less useful for another, and accounting choices or one-off events can make reported figures harder to compare.
- Fiscal period and seasonality
- Revenue growth and the factors driving it
- Margins, operating costs, and material changes
- Net income compared with cash from operating activities
- Liquidity, debt, and other material obligations
- Accounting policies, estimates, share count, and per-share measures
- Disclosed risks and GAAP results compared with reconciled non-GAAP measures
Keep performance separate from valuation
Financial results help you assess the business; they do not answer whether the current share price is attractive. Valuation requires a separate analysis of price in context. Avoid turning a strong earnings report, a favorable ratio, or a single period of growth into a buy conclusion without considering what the stock costs and what assumptions that price reflects.
Scope of this guide
This process describes U.S. SEC reporting forms. Foreign issuers may use different SEC forms, and companies outside the SEC reporting system may follow other disclosure regimes. The filings can inform investment research, but they do not predict returns or provide a personalized recommendation.
