How to Read a 10-K: Where Each Answer Lives

The map: four parts, 23 items

Every 10-K follows the same skeleton, so learning one filing teaches you all of them. Apple's 10-K for the fiscal year ended 27 September 2025 is a clean specimen. Part I has seven items: 1 Business, 1A Risk Factors, 1B Unresolved Staff Comments, 1C Cybersecurity, 2 Properties, 3 Legal Proceedings and 4 Mine Safety Disclosures. Part II has nine: 5, the market for the stock and the company's own share purchases; 6, which now reads [Reserved]; 7, Management's Discussion and Analysis; 7A, market risk; 8, the financial statements; 9, changes in and disagreements with accountants; 9A, Controls and Procedures; 9B, Other Information; and 9C, about foreign jurisdictions that prevent inspections.

Part III holds five items on governance and pay: 10 directors and executive officers, 11 executive compensation, 12 security ownership, 13 related transactions and director independence, and 14 the fees paid to the auditor. Part IV holds two: 15 the exhibits and financial statement schedules, and 16 the Form 10-K Summary.

The page numbers in the table of contents tell you where the weight is. In Apple's report, Risk Factors run from page 5 to page 17, twelve pages. Management's Discussion and Analysis runs from 21 to 27, six pages. The financial statements and their notes run from 28 to 52, twenty-four pages. All five Part III items sit on page 53, because each one says it will be included in the company's definitive proxy statement, to be filed within 120 days after the fiscal year end, and incorporates it by reference.

Find the real heading, not the first match

The obvious way to reach a section is to search for it, and the obvious way is wrong. In Apple's fiscal 2025 10-K the phrase Item 1A appears five times. The first is the table of contents. The second is a forward-looking statements warning that points readers to the risk factors. The third is the section heading itself, about 12% of the way into the text. The fourth sits in the cybersecurity item and the fifth in the gross margin discussion, both telling you to see Item 1A.

Two habits fix it. Read the page number from the table of contents and jump to the page instead of the first hit. Or search for the heading with its title, Item 1A. Risk Factors, and skip any match that sits inside a sentence. A match that says see Item 1A or discussed in Part I, Item 1A is a signpost, not the section. Software hits the same trap, which is why the parser behind our filing pages does not trust the first match either: open a 10-K from any company's filing list here and each item is jump-linked, or the page shows the plain document when the sections cannot be found with confidence.

Read it in the order the answers arrive

Start with Item 7, Management's Discussion and Analysis: management's own account of what changed in the year and why, in prose. It tells you which numbers management thinks matter, which is worth knowing before you look at the numbers.

Then read Item 8, the financial statements and their notes, with the auditor's report in front. In Apple's report the auditor also gives an opinion on internal control over financial reporting, which ties to the management report on the same subject in Item 9A. The notes are where the detail lives: debt maturities, leases, segments, tax, commitments and contingencies.

Then Item 1A, and read it against last year's. Risk factors are long and mostly stable from year to year, so the new paragraph matters more than the familiar ones, and the filing pages here link a view of what changed in a section since the previous comparable filing. Then Item 3 for legal proceedings, Item 7A for market risk (Apple's names interest rates and foreign exchange rates) and Item 5, whose full title ends with Issuer Purchases of Equity Securities, for share buybacks.

Item 9B, Other Information, is worth ten seconds. The SEC staff allows an event that would normally need a Form 8-K, and that happens within four business days before the 10-K is filed, to be reported in Item 9B instead, except changes of auditor and non-reliance on past financial statements, which always need their own 8-K. A late event can surface there.

Set it against the earnings release

The earnings release comes first and the 10-K follows. Apple furnished its fourth-quarter results on a Form 8-K under Items 2.02 and 9.01 on 30 October 2025 and filed the 10-K on 31 October, 34 days after its fiscal year ended. The release carries the headline figures. The 10-K adds what a release leaves out: the risk factors, the notes, the controls report and the auditor's opinion.

That gap is the reason to read both. A figure that appears in the release and in Item 8 should match; a figure that appears only in the release, such as a non-GAAP measure, is management's choice of presentation. Our statement viewer lays out the filed figures for any company so you can check the two against each other.

What the 10-K cannot tell you

A 10-K describes a fiscal year that has already ended. Anything that happens afterwards arrives on other forms: a material event on an 8-K, generally within four business days; an insider trade on a Form 4 before the end of the second business day after the trade; the next quarter on a 10-Q. Governance and pay, as Apple's Part III shows, may arrive weeks later in the proxy statement.

So read the 10-K as the deepest single snapshot, then read the filings around it. A company's filing list on this site groups everything it has filed by type, annual and quarterly reports next to registrations, ownership filings and material events, and which filing explains a drop walks through the event-driven forms one question at a time.
