Form 10-Q: The Quarterly Report (and Why Q4 Is Missing)
Form 10-Q is the quarterly financial report publicly traded companies file with the SEC — but only three are filed each year because the fourth quarter is covered by the annual 10-K. This explainer covers the filing schedule, the lighter review standard versus an audit, the shorter deadline, and how to extract Q4 numbers by subtraction.

What Is a 10-Q?
A Form 10-Q is an unaudited quarterly report that publicly traded companies must file with the SEC to disclose their financial performance and material events for the most recent fiscal quarter. It includes a balance sheet, income statement, cash flow statement, and a Management's Discussion and Analysis (MD&A) section where executives explain what drove the numbers.
Unlike the annual 10-K, the 10-Q is not audited. Instead, an independent accountant performs a "limited review" — a lighter check that focuses on whether the financial statements appear reasonable and consistent with prior periods. The SEC requires the 10-Q to be filed within 40 or 45 days after the end of the quarter, depending on the company's size.
The Missing Fourth Quarter: Why Only Three 10-Qs Per Year
A company with a fiscal year ending December 31 files 10-Qs for the first, second, and third quarters — that's Q1, Q2, and Q3. The fourth quarter (Q4) is not reported separately in a 10-Q because the annual 10-K covers the entire fiscal year, including Q4.
To see standalone Q4 results, you must subtract the cumulative figures from the Q3 10-Q from the full-year figures in the 10-K. For example, if the 10-K shows $100 million in annual revenue and the Q3 10-Q shows $70 million year-to-date through September, Q4 revenue was $30 million.
Review vs. Audit: What the Limited Review Covers
The 10-Q's financial statements undergo a "limited review" (also called a "review") by the company's independent public accountant. This is less rigorous than a full audit. The accountant reads the statements, makes inquiries of management, and performs analytical procedures — but does not test internal controls, confirm receivables, or verify inventory counts.
Because of this lighter standard, the 10-Q carries no audit opinion. The cover page of the 10-Q will state that the financial statements are "unaudited" and that the review was performed in accordance with Statements on Standards for Accounting and Review Services. If the accountant finds any material modifications needed, they will note it in a review report.
Filing Deadlines: 40 or 45 Days After Quarter End
The deadline for filing a 10-Q depends on the company's public float (the market value of shares held by non-affiliates). Large accelerated filers (public float of $700 million or more) and accelerated filers (public float between $75 million and $700 million) must file within 40 days after the end of the fiscal quarter. All others — non-accelerated filers and smaller reporting companies — have 45 days.
For a calendar-year company, the Q1 10-Q (quarter ending March 31) is due by May 10 if accelerated, or May 15 if non-accelerated. The Q2 and Q3 deadlines follow the same pattern. If a company cannot file on time, it may file Form NT 10-Q to request a five-day extension, but the reason must be disclosed.
What to Look For in a 10-Q
Most 10-Qs are routine filings that show steady results. The key sections to focus on are the MD&A (Item 2), where management compares the current quarter to the same quarter last year and explains changes in revenue, margins, and cash flow; and the financial statements (Item 1), which include the balance sheet, income statement, and cash flow statement.
Also check Item 1A (Risk Factors) — companies often update risk factors in the 10-Q to reflect new developments. Item 4 (Controls and Procedures) states whether management has identified any material weaknesses in internal controls. A sudden change in accounting policies, unexpected write-offs, or a large drop in cash from operations are red flags worth investigating.
When a 10-Q Might Be Especially Important
Most 10-Qs are uneventful, but they become critical when a company warns of deteriorating results, announces a change in auditors, or reveals a material weakness in internal controls. A 10-Q can also contain adjusted earnings per share (EPS) figures that differ from GAAP, so read the footnotes carefully.
Because the 10-Q is filed more quickly than the 10-K, it often contains the earliest public signal of a company's true trajectory. The SEC also requires companies to file amended 10-Qs (Form 10-Q/A) if errors are discovered after the original filing — a correction that can itself be a red flag.
Common questions
Why don't companies file a 10-Q for the fourth quarter?
Because the annual 10-K covers the entire fiscal year, including the fourth quarter. Reporting Q4 separately in a 10-Q would be redundant. Instead, companies combine Q4 into the 10-K, which is audited and filed later (within 60 to 90 days after year-end, depending on company size).
How do I find the Q4 revenue or profit for a company?
Take the full-year figure from the income statement in the company's 10-K and subtract the year-to-date figure from the last 10-Q (usually the third-quarter filing). For example, if the 10-K shows $400 million in annual revenue and the Q3 10-Q shows $310 million through September, Q4 revenue was $90 million.
Are the financial statements in a 10-Q audited?
No. They are reviewed by an independent accountant, but not audited. The review is limited to inquiries and analytical procedures. An audit would include verification of inventory, accounts receivable, and testing of internal controls, none of which are required for a 10-Q.
What is the deadline to file a 10-Q?
It depends on the company's public float. Large accelerated filers (float ≥ $700 million) and accelerated filers (float ≥ $75 million but < $700 million) must file within 40 days after the end of the quarter. All other filers have 45 days. For a company using a calendar year, the Q1 10-Q is due by May 10 (accelerated) or May 15 (non-accelerated).
What is the difference between a 10-Q and a 10-K?
A 10-Q is filed quarterly (three times a year) and covers one fiscal quarter. Its financial statements are unaudited and undergo only a limited review. The 10-K is annual, covers the entire fiscal year, includes the fourth quarter, and its financial statements are fully audited. The 10-K also includes a more detailed business description, audited financial statements, and risk factors.
