Form 10-K vs. 10-Q Explained: Differences and Where to Look

Form 10-K is the annual report that U.S. public companies file with the Securities and Exchange Commission, and Form 10-Q is the shorter quarterly report filed for the first three fiscal quarters. The 10-K contains audited financial statements and a full description of the business and its risks. The 10-Q contains unaudited, condensed statements and an update on the period since the last report. Together they form the core of the periodic disclosure system that lets anyone read a company’s reported results for free.

In brief

• 10-K: annual, audited, comprehensive.
• 10-Q: quarterly, reviewed rather than audited, condensed.
• There is no 10-Q for the fourth quarter. The 10-K covers the full year, including the fourth quarter.
• Both are available free on the SEC’s EDGAR database.
• Deadlines depend on the company’s filer status. Check the form instructions on SEC.gov for the current schedule.

What each form is

Form 10-K

The 10-K is the annual report required of most companies that have registered securities under the Securities Exchange Act of 1934. Its structure is set by the SEC’s form instructions and is organized into parts and numbered items. The SEC’s investor education material explains that the 10-K gives a comprehensive overview of the business and its financial condition, and that it includes audited financial statements.

Principal sections include:

• Business (Item 1). What the company does, its products, customers, competition, regulation and, in many cases, employees.
• Risk factors (Item 1A). The risks management considers material to the company.
• Unresolved staff comments (Item 1B). Open comments from SEC staff, where applicable.
• Properties and legal proceedings (Items 2 and 3).
• Market for equity (Item 5). Where the shares trade, holders, dividends and repurchases.
• Management’s discussion and analysis, known as MD&A (Item 7). Management’s explanation of results, liquidity and trends.
• Financial statements and supplementary data (Item 8). The audited statements with notes, plus the auditor’s report.
• Controls and procedures (Item 9A). Management’s assessment of internal control over financial reporting.
• Executive compensation, directors and governance (Part III). Often incorporated by reference from the proxy statement.

Form 10-Q

The 10-Q is the quarterly report. It provides interim financial statements and a shortened discussion. Its main parts are:

• Part I, financial information. Condensed financial statements, MD&A, quantitative and qualitative disclosures about market risk, and controls and procedures.
• Part II, other information. Legal proceedings, updates to risk factors, share repurchases, defaults on senior securities and exhibits.

The statements in a 10-Q are unaudited. They are, however, subject to a review by the company’s independent auditor under professional standards for interim reviews. A review is less extensive than an audit.

Audit status and why it matters

An audit provides reasonable assurance, in the auditor’s opinion, that the financial statements are free of material misstatement. A review of interim financial statements consists mainly of inquiries and analytical procedures and provides less assurance. The 10-K’s audit opinion is therefore a higher level of comfort than the 10-Q’s. That does not make quarterly figures unreliable; it means annual figures have been tested more thoroughly. Public companies’ audits are overseen by the Public Company Accounting Oversight Board.

Timing and filer categories

The SEC sets filing deadlines by form and by the size category of the filer, such as large accelerated filer, accelerated filer, or non-accelerated filer. Larger companies by market value of public float generally have shorter deadlines than smaller ones, and the 10-K deadline is later than the 10-Q deadline measured from period end. The exact day counts are in the General Instructions to Forms 10-K and 10-Q, and readers should confirm them on SEC.gov rather than relying on a summary. Late filers must disclose that on Form 12b-25, which grants a limited extension if conditions are met.

The earnings release usually precedes the filing. Companies commonly announce results in a press release furnished on Form 8-K, then file the 10-Q or 10-K shortly after or on the same day. Our guide to reading an earnings release covers that first document.

Key differences at a glance

Feature	Form 10-K	Form 10-Q
Frequency	Once a year	Three times a year (first three quarters)
Financial statements	Audited, full year	Unaudited but reviewed, condensed
Business description	Comprehensive	Not repeated
Risk factors	Full discussion	Updates to the 10-K only
MD&A	Full	Shorter, focused on the quarter
Executive pay and governance	Part III, often by reference	Not included

What to read first

Different questions point to different sections.

1. How did the business do? Start with MD&A, then confirm in the financial statements.
2. What could go wrong? Read risk factors in the 10-K. In the 10-Q, check whether they changed.
3. How is the company financed? The balance sheet, liquidity discussion and debt footnotes.
4. What is management not saying plainly? Footnotes on revenue recognition, contingencies, related parties and subsequent events.
5. Is anything unusual? Look at the auditor’s report in the 10-K for language such as a going concern paragraph or critical audit matters, and at the 10-Q’s controls section for any changes.

A practical technique is to read the latest 10-Q alongside the matching quarter in the prior year’s filings. The change in language often tells more than the change in numbers.

How to find them

All filings are on the SEC’s EDGAR database at SEC.gov. Search by company name or ticker, then filter by form type. Recent filings often include interactive financial data. The SEC also publishes plain-English guidance on reading both forms, listed in the sources below.

Related forms

• Form 8-K. Current reports on specific events such as earnings, executive departures, acquisitions and bankruptcy.
• Form 10-K/A and 10-Q/A. Amendments to a filed report.
• Form 20-F and Form 40-F. Annual reports used by many foreign private issuers instead of the 10-K.
• Form 6-K. Interim reports by foreign private issuers.
• Proxy statement (DEF 14A). Executive compensation, board matters and shareholder votes.

Common misconceptions

• “The 10-Q is a mini 10-K.” It is narrower and only updates the 10-K. It does not repeat the business description.
• “There are four 10-Qs.” There are three. The fourth quarter appears in the 10-K.
• “Everything in a 10-K is audited.” The financial statements and related notes are covered by the audit. MD&A and risk factors are management’s statements.
• “Small companies do not file these.” Smaller reporting companies file the same forms, with some scaled disclosure.
• “The earnings release and the 10-K always match.” They should agree in substance, but the filing can include final adjustments or more detail.

Key terms

• Fiscal year. The twelve-month period a company uses for accounting. It need not end in December, and the 10-K deadline runs from the fiscal year end.
• Public float. The market value of shares held by non-affiliates. It helps determine the filer category.
• Smaller reporting company. A category that may provide scaled disclosure in some items.
• Internal control over financial reporting. Processes designed to give reasonable assurance about reliable financial reporting. Management assesses it annually, and larger filers also receive an auditor’s attestation.
• Subsequent events. Developments after the balance sheet date that may need to be disclosed in the notes.
• XBRL. The structured data format in which financial statements are tagged, allowing software to read the numbers directly from EDGAR.

A reading routine for each form

For a 10-Q, a ten-minute pass can cover the cover page and period, the three statements, the MD&A discussion of changes, the legal proceedings and risk factor updates in Part II, and the exhibit list. For a 10-K, add the business description, the full risk factors, the critical accounting estimates inside MD&A and the notes on revenue, debt, taxes and commitments. Comparing the same section across years, using the filing index on EDGAR, shows what management has added or removed.

FAQ

Which is more important, the 10-K or the 10-Q?

Neither is more important in general. The 10-K is the fuller and audited source; the 10-Q is the most current. Together they track a company across the year.

Why is there no 10-Q for the fourth quarter?

Because the 10-K covers the whole fiscal year. Fourth-quarter results can be derived from the annual figures, and many companies present them in the earnings release.

Are 10-K and 10-Q filings free?

Yes. EDGAR is free to use, and filings can be viewed and downloaded without an account.

Do all public companies file these forms?

Most U.S. domestic registrants do. Foreign private issuers generally use different forms, and some companies with limited reporting obligations file less.

What is the difference between a 10-K and an annual report to shareholders?

The annual report to shareholders is a glossy document some companies send with the proxy materials. The 10-K is the legal filing. Some companies combine them.

Where do I check the filing deadline?

In the General Instructions to Forms 10-K and 10-Q on SEC.gov, which set deadlines by filer category.
