An “annual report” may mean the 10-K or a separate report prepared for shareholders. That shareholder report overlaps with the 10-K, is often less detailed, and may be the same document—so check which document you have.
How the three documents differ
| Document | Cadence and audience | What it contains | Financial statements and use |
|---|---|---|---|
| Form 10-K | Annual SEC filing by most U.S. public companies | Detailed disclosures about the business, risks, annual results, management’s discussion and required information | Annual financial statements are audited in the cited filing example. Use it for the company’s broad annual picture and detailed disclosures. |
| Form 10-Q | Quarterly SEC filing | Interim financial statements and notes, management’s discussion and analysis, and other required quarterly disclosures | The cited filing labels its interim statements unaudited. Use it to check more recent interim developments against prior periods. |
| Annual report to shareholders | Shareholder communication associated with the annual meeting | Information that overlaps with the 10-K, often in a more polished presentation; it may be less detailed | It may be a separate document or the same document as the 10-K. Confirm which one you are reading. |
The SEC describes both possibilities: a company may publish a separate shareholder annual report, or use its 10-K for that purpose. Do not assume the documents are always separate or always identical. SEC Investor Bulletin: How to Read a 10-K
What a 10-K and 10-Q contain
Form 10-K: the annual picture
The 10-K is a structured filing that includes business and risk disclosures, annual financial results, management’s discussion, governance and compensation information, and exhibits. Some information—such as particular governance details—may be incorporated by reference from a proxy statement, so the 10-K may direct you to a separate filing. The SEC advises that the “Business” section is a good place to start. SEC Investor Bulletin: How to Read a 10-K
Form 10-Q: the interim update
A sample 10-Q’s Part I includes financial statements and notes, management’s discussion and analysis, market-risk disclosures, and controls and procedures. Part II includes additional items such as legal proceedings, risk factors, other information, and exhibits. The sample labels its interim financial statements unaudited; the exact presentation and contents can vary by issuer. Apple Inc. Form 10-Q

Are 10-Q financial statements audited?
Do not treat a 10-Q’s interim financial statements as audited: the cited 10-Q explicitly labels them unaudited. By contrast, the cited 10-K presents annual financial statements audited by an independent registered public accounting firm. These filing examples show the distinction, but for a specific company, check the filing’s own statements and auditor’s report rather than assuming every assurance detail is identical across issuers. 10-Q example; 10-K example
How to read the filings efficiently
Start with the 10-K
- Read Business and Risk Factors. These sections explain what the company does and the risks it identifies.
- Review Management’s Discussion and Analysis. Use management’s account of results and changes to guide what you examine in the statements.
- Read the financial statements and notes. Notes provide detail behind the reported figures; follow any references to information incorporated from another filing.
Then use the 10-Q for changes
- Compare the latest interim results with the same period a year earlier. A year-over-year comparison helps distinguish a recent change from seasonal patterns.
- Read the 10-Q’s management discussion and notes. Look for explanations of changes in results, risks, or other disclosures since the prior report.
- Check the latest 10-K for context. The quarterly report is an update, not a replacement for the fuller annual disclosures.
These steps are a practical reading order, not a substitute for reviewing material disclosures throughout the filing. Both forms include CEO and CFO certifications of financial and certain other information under SEC reporting guidance. A certification does not mean the SEC wrote the report or vouches for its accuracy; the SEC says it neither writes the 10-K nor vouches for its accuracy.

Where to find a company’s 10-K or 10-Q
Search the company’s filings through the SEC’s EDGAR company search, where required electronic filings become publicly available upon filing. Most companies also post their 10-Ks on their websites, according to the SEC investor guide. When using a company website, make sure you have the SEC filing itself if you need the formal disclosure.

Deadlines depend on the filer category, and the due date can shift for weekends and federal holidays; extensions may also apply. The SEC Financial Reporting Manual gives the following general framework, but its cited deadline section was last updated in 2020.

Which document should you use?
- For the fullest annual disclosure: Start with the 10-K.
- For the latest quarterly update: Read the 10-Q alongside the comparable prior-period results and the latest 10-K.
- For a shareholder-facing overview: The annual report may be easier to browse, but verify whether it is the 10-K or a separate, less detailed publication.
