How to Read a 10-K Filing

On this page:

Form 10-K is the annual disclosure document every U.S. public company files with the SEC. It typically runs well over 100 pages, but three sections — Item 1A (Risk Factors), Item 7 (MD&A) and Item 8 (Financials) — carry most of the analytical content.

This guide covers what a 10-K is, why it matters, and how to read Item 1A, 7 and 8.

What Is a 10-K?

It is the annual report every U.S. public company must file with the SEC under Section 13 or 15(d) of the Securities Exchange Act of 1934. It's a comprehensive, audited snapshot of the company's business, financial condition, and risks for the fiscal year — far more detailed than the annual report a company might mail to shareholders.

A 10-K is organized into four parts: Business and Operations, Financial Data and Analysis, Governance and Leadership, and Exhibits and Schedules. It contains 16 numbered items, with key sections delivering the newest, most actionable intelligence on a company's financial health:

  • Business description (Item 1) — what the company does, its markets, competition, employees
  • Risk and performance narrative (Items 1A and 7) — what could go wrong, and how the year actually went
  • Financial statements (Item 8) — audited GAAP financials and footnotes

Companies must file within 60, 75, or 90 days of fiscal year-end, depending on filer size (large accelerated, accelerated, or non-accelerated filer).

Benefits of Reading a 10-K

  • It's audited. Item 8's financial statements carry an independent auditor's opinion — a higher bar than an earnings release or investor deck.
  • It's comparable year over year. Because the SEC standardizes the structure, this year's items can be diffed directly against last year's to see what changed.
  • It's the primary source. Analyst notes and financial media are downstream of the 10-K. Reading it directly removes a layer of interpretation.

Regulations and Requirements

The 10-K's structure is set by SEC Regulation S-K, which specifies exactly what each item must contain. See official instructions and item requirements.

  • Item 1A (Risk Factors) is required under Regulation S-K Item 105 — a discussion of the material risks specific to the company, not generic industry risk.
  • Item 7 (MD&A) is required under Regulation S-K Item 303 — management's own narrative explanation of results, liquidity, and capital resources, written in plain English.
  • Item 8 (Financial Statements) must comply with Regulation S-X and be audited by a registered public accounting firm under PCAOB standards.

Smaller reporting companies get some relief — a shorter Risk Factors item is allowed, and certain MD&A disclosures are scaled down. See the SEC's smaller reporting company resources for the exact thresholds. Both sections remain mandatory for every filer, large or small. Amendments are filed as Form 10-K/A.

Deep Dive: Risk Factors (Item 1A), MD&A (Item 7), Financials (Item 8)

These three items carry most of the analytical value in a 10-K, and they answer three different questions.

Item 1A — Risk Factors: This is a company's own disclosure of the material risks facing its business — competitive, operational, regulatory, financial, and legal. Risk factors are supposed to be specific to the company, not boilerplate industry risk, though in practice many are reused year over year with light edits. The highest-value read isn't the list itself — it's the difference: risk factors that are new this year, reworded, or dropped entirely often signal a shift management hasn't stated outright anywhere else in the filing.

Item 7 — MD&A: Management's Discussion and Analysis is the narrative counterpart to the audited numbers in Item 8. It typically covers:

  • Results of operations, with explanations for period-over-period changes
  • Liquidity and capital resources — cash position, credit facilities, capital commitments
  • Critical accounting estimates that required significant management judgment
  • Known trends or uncertainties expected to affect future results

Because MD&A is written by management rather than derived purely from the numbers, it's the section where tone matters: hedging language, new "known trends" disclosures, and shifts in how a metric is framed are often earlier signals than the financials themselves.

Item 8 — Financial Statements: This is the consolidated balance sheet, income statement, statement of cash flows, and statement of stockholders' equity, together with the accompanying notes — all audited by a PCAOB-registered accounting firm under Regulation S-X. The notes carry most of the technical detail: revenue recognition policy, debt covenants, contingencies, and segment reporting broken out in more granular form than Item 7's narrative gives. Since 2009, this data must also be tagged in machine-readable XBRL, which structures every line item so it can be pulled directly rather than parsed out of the filing text.

Tesla's FY2025 10-K shows: Item 1A flagged tariff risk to its supply chain. Item 7 reported the result — revenue down to $94.83B, net income down to $3.79B, citing tariffs and Robotaxi investment. Item 8 certifies those numbers.

Read together: Item 1A tells you what management is worried about, Item 7 tells you what already happened and why, and Item 8 gives you the audited numbers underneath both. Reading several years of all three side by side is usually more informative than reading any one of them in isolation for a single year.
