An SEC Form 10-K is the comprehensive, audited annual report a public company files with the SEC — a full description of the business, its risk factors, management’s discussion of the results, and a complete set of audited financial statements. It is the single most complete public document a company produces about itself.
The 10-K is organised into standard, numbered items, so the same kind of information sits in the same place for every company: Item 1 (Business) — what the company does, its products, markets, and competition; Item 1A (Risk Factors) — the specific things management says could hurt the business; Item 7 (MD&A, Management’s Discussion & Analysis) — management explaining why the numbers moved; and Item 8 (Financial Statements) — the audited income statement, balance sheet, and cash-flow statement plus their notes.
Because the financials are audited and the format is standardised, the 10-K is the primary source most other numbers on this site — fundamentals, margins, debt — ultimately trace back to.
The three are different reporting rhythms. A 10-K is annual and audited — the deep, once-a-year document. A Form 10-Q is the lighter quarterly update filed the other three quarters, and is unaudited. A Form 8-K is the "current report" filed within a few business days of a specific material event, in between the periodic reports. Read together: the 8-K tells you something just happened, the 10-Q gives the quarterly scorecard, and the 10-K is the full annual picture.
You do not have to read all 200-plus pages. A common approach is to start with the MD&A (Item 7) for management’s narrative, skim the Risk Factors (Item 1A) for what changed versus last year, and then check the audited statements (Item 8) for the trends that narrative is describing. Quantustik’s Academy path, "Reading a 10-K without a finance degree," walks a first-time reader through exactly this, section by section. Every 10-K is free to read on the SEC’s EDGAR system.
A 10-K is the annual report and its financial statements are audited by an independent firm. A 10-Q is the lighter quarterly report filed the other three quarters, and it is unaudited. The 10-K is deeper; the 10-Q is more frequent.
Yes. The financial statements in a 10-K (Item 8) are audited by an independent public accounting firm, which is a key reason the 10-K is treated as the authoritative annual source — unlike the quarterly 10-Q, which is unaudited.
Every 10-K is public and free on the SEC’s EDGAR system. Quantustik also surfaces new 10-K filings across the tracked S&P 500 in its 10-K filings feed, and its Academy path walks through how to read one section by section.
