10-K vs 10-Q: Annual & Quarterly SEC Filings Compared

10-K vs 10-Q: What Is the Difference?

The 10-K and 10-Q are the two most important financial filings that publicly traded companies submit to the Securities and Exchange Commission (SEC). The 10-K is a comprehensive annual report containing audited financial statements, detailed business descriptions, risk factors, and management analysis. The 10-Q is a shorter quarterly update with unaudited (but reviewed) financial statements and a condensed management discussion.

Every public company files one 10-K and three 10-Qs per year. Together, these four filings provide a continuous view of a company's financial performance. The 10-K covers the full fiscal year, while each 10-Q covers one of the first three fiscal quarters. There is no 10-Q for the fourth quarter because the 10-K already covers the entire year, including Q4 data.

For investors conducting fundamental analysis, the 10-K is the primary document. It contains information you will not find in any earnings press release, investor presentation, or analyst summary. The 10-Q is valuable for tracking how the business evolves between annual reports.

What Is a 10-K Filing?

The 10-K is the annual report that every public company must file with the SEC. It is the single most complete source of information about a company's financial condition, business operations, and risk profile.

A 10-K is organized into four main parts:

Part I covers the business description, risk factors, unresolved SEC staff comments, and properties. The risk factors section alone can run 20-30 pages for large companies, disclosing everything from competitive threats to regulatory risks.

Part II contains the financial statements and supplementary data. This includes the income statement, balance sheet, cash flow statement, and stockholders' equity statement, all audited by an independent accounting firm. It also includes Management's Discussion and Analysis (MD&A), which explains the numbers in context.

Part III covers executive compensation, board composition, and corporate governance. Some companies incorporate this by reference from their proxy statement.

Part IV lists financial statement schedules and exhibits, including material contracts, certifications, and subsidiary lists.

Apple's fiscal year 2024 10-K (filed in November 2024) runs over 80 pages. It discloses segment-level revenue, geographic breakdowns, and detailed notes on everything from lease obligations to derivative instruments.

What Is a 10-Q Filing?

The 10-Q is a quarterly report filed for each of the first three quarters of a company's fiscal year. It provides a financial update between annual 10-K filings but is less comprehensive in scope.

A 10-Q typically includes:

• Condensed financial statements (income statement, balance sheet, cash flow statement) that are reviewed but not fully audited by the company's independent auditor
• MD&A covering the quarter's results, comparing them to the same quarter in the prior year
• Quantitative and qualitative disclosures about market risk, such as exposure to interest rate changes or foreign currency fluctuations
• Legal proceedings updates
• Risk factor updates (only if there are material changes from the 10-K)

Apple files its 10-Q reports after each of its first three fiscal quarters (ending in December, March, and June). These filings are typically 30-40 pages, roughly half the length of the annual 10-K.

The key limitation of the 10-Q is the audit status. A "review" by an auditor involves analytical procedures and inquiries but is substantially less in scope than a full audit. This means the quarterly figures carry a slightly lower level of assurance than the audited annual figures.

10-K vs 10-Q: Side-by-Side Comparison

Filing Deadlines and Filer Categories

The SEC categorizes companies into three tiers based on public float (the market value of shares held by non-insiders):

Large accelerated filers have a public float of $700 million or more. These companies face the tightest deadlines: 60 days for the 10-K and 40 days for the 10-Q. Apple, Microsoft, and most S&P 500 companies fall into this category.

Accelerated filers have a public float between $75 million and $700 million. They get 75 days for the 10-K and 40 days for the 10-Q.

Non-accelerated filers (smaller reporting companies) have a public float below $75 million. They receive 90 days for the 10-K and 45 days for the 10-Q.

These deadlines are firm. Companies that miss them must file an NT 10-K or NT 10-Q (notification of late filing) explaining the delay. Repeated late filings can trigger SEC enforcement action and erode investor confidence.

How to Find 10-K and 10-Q Filings on EDGAR

The SEC's EDGAR (Electronic Data Gathering, Analysis, and Retrieval) database is the definitive source for all public company filings. Every 10-K and 10-Q ever filed electronically is available for free.

Step 1: Go to the SEC EDGAR full-text search at sec.gov/cgi-bin/browse-edgar.

Step 2: Enter the company name or ticker symbol (e.g., "AAPL" for Apple).

Step 3: Select the filing type. Enter "10-K" to see annual filings or "10-Q" for quarterly filings.

Step 4: Click "Search" and browse the results sorted by date. Each filing includes the full document, exhibits, and any amendments.

Most company investor relations pages also provide direct links to their SEC filings, often with interactive viewers that are easier to navigate than the raw EDGAR format.

What Investors Should Focus On

In the 10-K

• Risk factors: Read these carefully, especially for companies in rapidly changing industries. Management is legally required to disclose material risks.
• Revenue recognition policies: Found in the notes to financial statements. Understanding how a company recognizes revenue is essential for evaluating earnings quality.
• Segment reporting: Large companies break down revenue and profit by business segment, revealing which divisions drive growth.
• Off-balance-sheet arrangements: These can hide liabilities that do not appear on the main balance sheet.

In the 10-Q

• Revenue and earnings trends: Compare the current quarter to the same quarter last year to identify growth or deceleration.
• Cash flow changes: A sudden shift in operating cash flow can signal problems before they appear in earnings.
• Guidance updates: Companies sometimes update forward guidance in the MD&A section of their 10-Q.
• Legal proceedings: New lawsuits or regulatory actions often first appear in quarterly filings.

Building a diversified portfolio requires understanding the companies you own, and 10-K and 10-Q filings are the most reliable sources for that understanding.

Frequently Asked Questions

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

The fourth quarter's financial results are included in the annual 10-K filing, which covers the entire fiscal year. Filing both a Q4 10-Q and a full-year 10-K would be redundant. The 10-K provides audited full-year figures along with quarterly breakdowns in the notes, so investors still get Q4-specific data.

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

The 10-K is a standardized SEC filing with specific content requirements and legal disclosures. The annual report (sometimes called the glossy annual report) is a shareholder communication that companies voluntarily produce. It often includes photographs, letters from the CEO, and marketing language. Many companies now combine the two, using the 10-K as their annual report, but the 10-K is the legally binding document.

Can a company's 10-Q numbers change when the 10-K is filed?

Yes. Because 10-Q financial statements are reviewed rather than audited, the full-year audit can result in adjustments to previously reported quarterly figures. These adjustments are typically small, but in cases of accounting errors or restatements, they can be significant. The audited 10-K figures supersede any previously reported 10-Q numbers.

How do I know if a company filed its 10-K or 10-Q late?

If a company cannot meet the filing deadline, it must file an NT 10-K or NT 10-Q (the "NT" stands for "notification") with the SEC. This filing explains the reason for the delay and provides an expected filing date. You can search for NT filings on EDGAR. Chronic late filers may face SEC scrutiny, and the stock may be flagged or delisted by exchanges.
