Form 10-Q is the quarterly SEC filing required from most public companies within 40-45 days of each fiscal quarter end (Q1, Q2, Q3; Q4 is covered by the 10-K). It contains unaudited interim financial statements and updated MD&A. See sec.gov/forms and the SEC's EDGAR database at sec.gov/edgar for all 10-Q filings.
Form 10-Q is required under Section 13 or 15(d) of the Securities Exchange Act of 1934, the same authority underlying the 10-K. It provides investors with quarterly financial updates between annual reports, covering the three months of the relevant fiscal quarter. Content of Form 10-Q: Part I — Financial Information: - Unaudited condensed financial statements (balance sheet, income statement, cash flows) — reviewed by auditors under PCAOB standards (review, not audit) - Notes to interim financial statements (focusing on changes from prior year-end) - MD&A — management's discussion of results for the quarter, liquidity, and capital resources - Quantitative and qualitative disclosures about market risk Part II — Other Information: - Legal proceedings updates - Risk factor changes (only material changes from 10-K risk factors) - Unregistered securities sales - Exhibits and certifications (SOX 302 certifications) Filing deadlines: - Large accelerated filers (>$700M public float): 40 days after quarter end - All other filers: 45 days after quarter end Unaudited vs. audited: The 10-Q financial statements are reviewed by auditors (SAS 100 review procedures), not audited — lower scrutiny than the annual 10-K audit. This means 10-Q figures are more susceptible to restatement if errors are discovered. The annual 10-K's full audit provides higher assurance. Analytical use: Lenders and investors track quarterly 10-Q filings to monitor financial covenant compliance, detect early warning signs of distress (working capital deterioration, debt covenant pressure, revenue deceleration), and update credit assessments between annual reviews. Commercial banks use quarterly financial reporting requirements — modeled on 10-Q frequency — as covenant compliance monitoring triggers for large credit facilities. See sec.gov/edgar for EDGAR search.
The SEC designed the quarterly reporting regime to balance timeliness with accuracy. Full audits take weeks to months; quarterly audits would be impractical. Instead, the SEC requires independent auditor 'reviews' (less rigorous than audits) of 10-Q financials. Reviews check for anything that causes the auditor to believe the statements are materially misstated — catching major errors without the full audit burden. The annual 10-K must be fully audited.
Public companies file 10-Qs for Q1, Q2, and Q3 only. The fourth fiscal quarter financial results are covered by the annual 10-K, which includes audited full-year statements incorporating Q4. So public companies file three 10-Qs per year plus one 10-K covering all four quarters on a full-year audited basis.
