10-K anatomy

Part I — the business and its risks

• Item 1 — Business. Description of the business, segments, products, customers, competition, regulation, employees, intellectual property. Read this for any unfamiliar ticker; for a familiar one, scan for changes from prior year.
• Item 1A — Risk Factors. Management’s catalogue of what could go wrong. Most of it is boilerplate; the genuinely company-specific risks are usually the first three to five items.
• Item 1B — Unresolved Staff Comments. Anything the SEC has flagged but management hasn’t yet resolved. Usually empty; non-empty is interesting.
• Item 1C — Cybersecurity. Added 2023. Companies must describe their cybersecurity risk-management process and any material incidents.
• Item 2 — Properties. Physical assets — manufacturing plants, warehouses, leased office space. Useful for asset-heavy industries.
• Item 3 — Legal Proceedings. Material litigation. Read it if Item 1 mentioned ongoing disputes.
• Item 4 — Mine Safety. Mining companies only.

Part II — the financial story

• Item 5 — Market for Registrant’s Stock. Share price history, dividends paid, repurchase activity. The stock-repurchase table here is one of the cleanest disclosures of capital allocation behavior.
• Item 6 — Reserved. The old “Selected Financial Data” table; eliminated in 2021.
• Item 7 — MD&A. Management’s Discussion and Analysis. Where management explains why the financial results are what they are. The single most important narrative in the filing. Read it carefully; this is where forensic-accounting analysis lives.
• Item 7A — Quantitative and Qualitative Disclosures About Market Risk. Currency, commodity, and interest-rate exposures. Mostly relevant to financial firms and multinationals.
• Item 8 — Financial Statements and Supplementary Data. The audited financials themselves: balance sheet, income statement, cash flow statement, statement of stockholders’ equity, and the notes. Followed by the auditor’s report.
• Item 9 — Changes in and Disagreements with Accountants. Auditor turnover, especially mid-year, is a flag worth understanding.
• Item 9A — Controls and Procedures. Management’s assessment of internal controls, plus the auditor’s attestation. Material weaknesses disclosed here are diagnostic.
• Item 9B / 9C — Other Information / Foreign Jurisdictions. Catch-all and disclosure of operations in jurisdictions designated as concerning by HFCAA.

Parts III and IV — governance and exhibits

Part III (Items 10-14) covers directors, executive compensation, security ownership, related-party transactions, and audit-committee disclosures. Most companies incorporate these by reference to the proxy statement (DEF 14A), which is filed separately.

Part IV (Items 15-16) is the exhibit list and contractual references. The exhibit list at the end of any 10-K is its own gold mine — material contracts, employment agreements, credit facilities, and bylaws are all attached or incorporated by reference here.

Where to read first

For a forensic-accounting read of an unfamiliar ticker, the priority order is: Item 7 (MD&A) → Item 8 (the audited financials and notes) → Item 1A (risk factors) → Item 9A (controls). Item 1 is for context if you don’t know the company; the rest is for context if you have specific questions.

What to take away

The 10-K isn’t a document you read end-to-end. It’s a reference work you navigate by item code. Once you know the structure, you can find what you need in any company’s 10-K in under sixty seconds — and that’s the prerequisite to actually understanding any of it.
