How to Read SEC Filings
Clear, jargon-free answers to the questions investors actually ask about SEC filings — what each form and item means, and how to read the parts that matter. Educational reference only; nothing here is investment advice.
What is an SEC 8-K filing?
An 8-K is a "current report" that public companies file with the SEC to disclose major events between their regular quarterly and annual reports. Examples include earnings releases, executive changes, acquisitions, and bankruptcies. Most 8-Ks must be filed within four business days of the triggering event.

Item 5.02 of an 8-K discloses the departure, election, or appointment of a company's directors or principal officers — including the CEO, CFO, and board members. It covers resignations, terminations, retirements, and new hires, and often includes the terms of severance or new compensation arrangements.
Read explainer →What is a going-concern qualification?
A going-concern qualification is a warning — from a company's management or its auditor — that there is substantial doubt about the company's ability to continue operating for at least the next twelve months. It signals serious financial distress and appears in the notes to the financial statements or the auditor's report.
Read explainer →10-K vs 10-Q: what's the difference?
A 10-K is a company's comprehensive annual report; a 10-Q is a shorter quarterly report filed for the first three quarters of the year. The 10-K is audited and far more detailed; the 10-Q is unaudited (reviewed) and updates investors on recent quarterly performance. There is no fourth 10-Q because the 10-K covers the final quarter.
Read explainer →What is an EPS surprise and why does it matter?
An EPS surprise is the gap between a company's actual reported earnings per share and the consensus estimate analysts expected, usually stated as a percentage. A positive surprise (a "beat") means results exceeded expectations; a negative surprise (a "miss") means they fell short. Surprises often drive sharp short-term stock moves.
Read explainer →How do I read the Risk Factors section of a 10-K?
Read a 10-K's Risk Factors (Item 1A) to find what management believes could hurt the business. Focus on company-specific risks over generic boilerplate, note the order (most material tends to come first), and compare against the prior year to spot newly added risks — those additions are often the most telling.
Read explainer →What is an 8-K Item 2.02?
Item 2.02 of an 8-K is the "Results of Operations and Financial Condition" item — how public companies disclose quarterly and annual earnings. It is the filing that accompanies an earnings press release, typically attached as Exhibit 99.1, and is usually "furnished" to the SEC rather than formally "filed."
Read explainer →What does a 10-K MD&A section tell you?
MD&A — Management's Discussion and Analysis — is the section of a 10-K (and 10-Q) where management explains the numbers in plain language: why revenue and profit changed, the drivers behind them, liquidity and cash flow, and known trends or uncertainties. It is the narrative bridge between the raw financial statements and what they mean.
Read explainer →What is XBRL in SEC filings?
XBRL (eXtensible Business Reporting Language) is a machine-readable data format the SEC requires in financial filings. It tags each figure — like revenue or net income — with a standardized label, so computers can extract and compare financial data across companies automatically instead of parsing human-readable documents.
Read explainer →What is an 8-K Item 1.01?
Item 1.01 of an 8-K discloses that a company has entered into a "material definitive agreement" outside the ordinary course of business. Examples include major supply contracts, credit agreements, merger or acquisition agreements, and significant partnerships. It signals the company has committed to a consequential deal.
Read explainer →How soon after quarter-end must a company file a 10-Q?
A company must file its 10-Q within 40 days of the end of the fiscal quarter if it is a "large accelerated" or "accelerated" filer, and within 45 days if it is a smaller (non-accelerated) filer. The deadline depends on the company's public float and filing status, not on when it announces earnings.
Read explainer →What is a Form 4 and what does insider buying signal?
A Form 4 is a filing that corporate insiders — officers, directors, and holders of more than 10% of a company's stock — must submit to the SEC to report changes in their ownership, such as buying or selling shares. It is due within two business days of the transaction. Insider buying is often read as a bullish signal.
Read explainer →What is a proxy statement (DEF 14A)?
A proxy statement, filed as a DEF 14A, is the document a public company sends shareholders ahead of its annual meeting so they can vote by proxy. It discloses the matters up for a vote — director elections, auditor ratification, executive pay ("say-on-pay"), and shareholder proposals — along with detailed executive compensation tables.
Read explainer →What is a Form 13F and what does it reveal about hedge funds?
A Form 13F is a quarterly report that large institutional investors — hedge funds, mutual funds, and other managers with over $100 million in qualifying US equities — must file with the SEC listing their holdings. It reveals which stocks big money owns, but it is filed up to 45 days after quarter-end, so it shows a lagged snapshot.
Read explainer →What is a material weakness in internal controls?
A material weakness is a deficiency in a company's internal control over financial reporting serious enough that there is a reasonable possibility a material misstatement in the financial statements would not be prevented or caught in time. It is disclosed in the 10-K and is a meaningful red flag about financial-reporting reliability.
Read explainer →What is a Form S-1 (IPO registration statement)?
A Form S-1 is the registration statement a company files with the SEC to go public. It is the core disclosure document for an IPO, containing the business description, risk factors, audited financials, how the proceeds will be used, and ownership details. The prospectus that investors read is part of the S-1.
Read explainer →Schedule 13D vs 13G: what's the difference?
Schedule 13D and 13G are filed when an investor crosses 5% ownership of a public company. A 13D signals an active investor who may seek to influence or control the company — the classic activist filing. A 13G is for passive investors with no intent to influence control, and carries lighter, less frequent disclosure.
Read explainer →What is Regulation FD (Fair Disclosure)?
Regulation FD (Fair Disclosure) is an SEC rule that bars public companies from selectively sharing material non-public information with analysts or select investors before the public. If material information is disclosed selectively — even by accident — the company must promptly make it broadly public, often by furnishing an 8-K under Item 7.01.
Read explainer →What is a 424B prospectus?
A 424B is the final prospectus a company files with the SEC after its registration statement (such as an S-1 or S-3) is declared effective. It contains the completed terms of a securities offering — the actual price, number of shares, and use of proceeds. The number suffix (424B1 through 424B5) indicates what was finalized after the earlier filing.
Read explainer →What is a Form S-4 (mergers and acquisitions)?
A Form S-4 is the registration statement a company files when it issues new shares to fund a merger or acquisition — for example, in a stock-for-stock deal. It doubles as the combined proxy statement and prospectus sent to shareholders voting on the transaction, and it lays out the deal terms, background, financials, and risk factors.
