What is a 10-K filing?

A 10-K is the audited annual report U.S. public companies file with the SEC. It is the single most comprehensive disclosure a domestic registrant produces in any given year.

A 10-K is the annual report — comprehensive, audited, and required

The 10-K is filed once per fiscal year by every U.S. domestic public company under Section 13 or 15(d) of the Securities Exchange Act of 1934. It is far more comprehensive than the glossy "annual report to shareholders" mailed to investors — those are marketing documents; the 10-K is the disclosure document.

Filing deadlines depend on the company's public float: large accelerated filers (≥$700M public float) file within 60 days of fiscal year-end, accelerated filers within 75 days, and non-accelerated filers within 90 days.

What's inside a 10-K

Item 1 — Business: what the company does, its segments, customers, competition, regulation, and seasonality.
Item 1A — Risk Factors: forward-looking risks the company is required to disclose. Often the densest, most-read section.
Item 7 — MD&A: Management's Discussion and Analysis. The narrative that connects the financial statements to operating reality.
Item 8 — Financial Statements: income statement, balance sheet, cash-flow statement, and statement of stockholders' equity — all audited.
Item 9A — Controls: management's report on internal controls over financial reporting, plus the auditor's attestation (for accelerated filers).
Plus: properties, legal proceedings, market for equity, directors and executive officers, executive compensation, principal accountant fees, and exhibits.

10-K vs. annual report vs. proxy

These three disclosures get conflated regularly. The distinctions matter:

10-K: SEC-filed, audited, comprehensive. The legal disclosure.
Annual Report to Shareholders: mailed to shareholders, marketing-led, often wraps the 10-K in a glossy cover. Many companies now wrap-and-ship the 10-K as their annual report.
Proxy (DEF 14A): filed before the annual shareholders' meeting. Covers director elections, executive compensation, shareholder proposals.

10-K/A — amendments

When a company restates prior financials or corrects a 10-K already filed, it files a 10-K/A. SecFilingDex tracks 23 10-K/A amendments alongside originals so the historical disclosure record is complete. An amendment doesn't replace the original — both filings remain on the public record.

Our view

The 10-K is the most underused document on EDGAR. Most market commentary cites the press release; the actual disclosure language — particularly Item 1A risk factors and Item 7 MD&A — is where companies are required to be precise. Reading 10-Ks directly compounds. Anyone serious about a name should read at least the most recent two.
