How to read a 10-K in twenty minutes: five places the truth hides
An 84-page annual report has five sections that carry most of the information. Here is the order to read them in, tested on a real filing from February 2026.
- What happened
- Every US-listed company files an annual report on Form 10-K with the Securities and Exchange Commission, in a fixed order of items set by SEC rules. NVIDIA's most recent one, for the fiscal year ended January 25, 2026, was filed on February 25, 2026 and runs to 84 pages before exhibits.
- Why
- The order the SEC prescribes is not the order that rewards a reader with twenty minutes. Five sections — risk factors, the results table in the MD&A, the cash flow statement, five specific notes, and the auditor's report — hold most of what the other 70 pages describe.
- The numbers that matter

- Why it matters
- The 10-K is the one document a company signs under penalty of law, and it is free. Knowing where to look turns it from a doorstop into a twenty-minute check on any share you own or are thinking of owning.
- What happens nextas we saw it on 28 Sep 2026
- Companies with a December year-end and a public float of $700 million or more must file their FY2026 10-Ks within 60 days of December 31, 2026, that is by March 1, 2027 (31 days of January plus 28 of February bring the count to 59 on February 28, 2027).
The bigger the company, the sooner the report is due; NVIDIA filed its FY2026 report 31 days after year-end, well inside its 60-day limit.
| Large accelerated filer (public float $700m or more) | 60 |
|---|---|
| Accelerated filer ($75m to under $700m) | 75 |
| All other registrants | 90 |
| NVIDIA, actual, FY ended Jan 25, 2026 | 31 |
NVIDIA's annual report for the fiscal year ended January 25, 2026 runs to 84 pages before the exhibits, and 21 of those pages are risk factors. The people paid to read it go to five places, in an order the SEC's table of contents does not suggest, and get most of what matters in about twenty minutes.
This article sets out that order and tests it on one real filing, retrieved from EDGAR on September 28, 2026. Nothing here is a view on the company or its shares; it is a worked example of where to look.
What a 10-K is, and when it arrives
The SEC's investor bulletin “How to Read a 10-K/10-Q” (dated January 25, 2021) states that “SEC rules require that 10-Ks follow a set order of topics”, that the CFO and CEO “must certify to the accuracy of the 10-K”, and that the SEC “does not vouch for the accuracy” of the document.
Under 17 CFR 249.310(b), the report is due 60 days after fiscal year-end for large accelerated filers, 75 days for accelerated filers and 90 days for all other registrants. Rule 12b-2 defines a large accelerated filer as one whose common equity held by non-affiliates was worth $700 million or more at the end of its second fiscal quarter, and an accelerated filer as one in the $75 million to under-$700 million band.
Fiscal year-end January 25, 2026; filing date on EDGAR February 25, 2026. January 25 to February 25 is 31 days. Sixty days after January 25, 2026 is March 26, 2026. The cover page ticks “Large accelerated filer” and reports a public float of approximately $4.0 trillion as of July 25, 2025.
The five places, in order
1. Risk factors: read for the change, not the list
Item 1A is long by design. Regulation S-K Item 105 requires each risk under its own sub-caption, discourages generic risks, and, where the section runs past 15 pages, requires a summary of no more than two pages at the front. NVIDIA's runs from page 12 to page 32, so it carries a summary: 24 bullets under headings such as “Risks Related to Our Industry and Markets” and “Risks Related to Demand, Supply, and Manufacturing”.
A risk that appears every year is boilerplate. A risk that is new, longer, or higher up the list is the company's lawyers telling you what worried them in the past twelve months. The quickest way to find it is to open the prior 10-K in a second tab and compare the summary bullets side by side.
In NVIDIA's case the filing records a $4.5 billion charge in the first quarter of fiscal 2026 relating to H20 products after new export licensing requirements in April 2025, and states that at the end of fiscal 2026 the company was “effectively foreclosed from competing in China's data center computing/compute market”.
2. MD&A: the one table and the customer paragraph
The SEC bulletin describes Item 7 as the section where management “tells its story in its own words”. The story is optional; the results-of-operations table is not. It puts the year's revenue and cost lines beside the prior year with a percentage change, and it is where a company that reports adjusted earnings must reconcile them to GAAP.
| Line | FY2026 | FY2025 | Change |
|---|---|---|---|
| Revenue | 215,938 | 130,497 | +65% |
| Gross profit | 153,463 | 97,858 | +57% |
| Research and development | 18,497 | 12,914 | +43% |
| Operating income | 130,387 | 81,453 | +60% |
| Other income, net | 9,022 | 1,034 | — |
| Net income | 120,067 | 72,880 | +65% |
The Concentration of Revenue paragraph states that for fiscal year 2026 “sales to one direct customer represented 22% of total revenue and sales to another direct customer represented 14% of total revenue”. A year earlier the largest was 12%. This paragraph, not the narrative, is where concentration is quantified.
A text search of the filing for “non-GAAP” returns zero results. Where a 10-K does present non-GAAP numbers, the SEC bulletin notes the company “must also show how they differ from the most comparable corresponding GAAP financial measure”, and that reconciliation is the table to read.
3. Cash flow against net income
The income statement records what was earned; the cash flow statement records what arrived. The gap between the two is the most useful number in the document, and the reconciling lines explain it.
Three lines explain most of the gap. Accounts receivable rose by $15,399 million (sales booked but not yet collected), inventories rose by $11,324 million, and $8,918 million of net gains on equity securities counted in net income but produced no operating cash. Working the other way, stock-based compensation of $6,386 million was an expense that cost no cash. Inputs: cash flow statement, fiscal year ended January 25, 2026.
A ratio below 100% is normal for a fast-growing company, because growth ties up cash in receivables and stock. It becomes one of the accounting red flags when it falls year after year while reported profit rises, or when the gap sits in lines a reader cannot trace. Here every line is traceable, which is the test.
4. Five notes worth the detour
Most readers skip the footnotes, which is where the estimates, the obligations and the fine print live. Five repay the time:
- Revenue recognition. How and when sales are booked, plus remaining performance obligations. NVIDIA reports $2.3 billion of revenue from contracts longer than a year still to be recognized as of January 25, 2026.
- Debt and its maturities. NVIDIA's Note 11 lists notes from a 3.20% issue due 2026 ($1,000 million) to a 3.70% issue due 2060 ($500 million), a net carrying amount of $8,468 million and a short-term portion of $999 million.
- Leases. Lease liabilities are debt by another name.
- Stock-based compensation. The note gives the unrecognized cost still to come and the shares behind it.
- Related parties. Transactions with directors, officers or affiliates.
5. The auditor's report and its critical audit matters
The auditor is the only outsider who has seen the books, and under PCAOB rules must say in its own report which parts of the audit were hardest, or state that there were none.
PCAOB Auditing Standard 3101 defines it as a matter communicated to the audit committee that “relates to accounts or disclosures that are material to the financial statements” and “involved especially challenging, subjective, or complex auditor judgment”. Paragraph .14 requires each to be identified, with the reasons it was chosen and how it was addressed.
The report is signed “PricewaterhouseCoopers LLP, San Jose, California, February 25, 2026”, with the line “We have served as the Company's auditor since 2004”. The single critical audit matter is “Valuation of Inventories — Provisions for Excess or Obsolete Inventories and Excess Product Purchase Commitments”. As of January 25, 2026, the auditor notes, inventories were $21.4 billion and inventory purchase and long-term supply and capacity obligations were $95.2 billion, with provisions resting on “assumptions about future demand including the impact of market conditions such as regulatory export restrictions”.
That is the auditor saying, in a page, which estimate in 84 pages it found hardest to test. The SEC bulletin adds that a “qualified opinion”, a “disclaimer of opinion” or a material weakness in internal control are the signals to read carefully.
Two minutes more: Item 9B holds anything that should have gone in a Form 8-K in the fourth quarter but did not; in NVIDIA's filing it lists directors and officers who adopted, modified or terminated Rule 10b5-1 trading plans. Item 15's exhibit index is where material contracts, the subsidiaries list and the CEO and CFO certifications (Exhibits 31 and 32) are filed.
Finding any of this in seconds
EDGAR full-text search at sec.gov/edgar/search covers, in the SEC's words, “the full text of all EDGAR filings submitted electronically since 2001”, exhibits included. Put a phrase in quotation marks to match it exactly and filter by form type and company. Inside one filing, the browser's find function on “Critical Audit Matter”, “Concentration” and “Net cash provided by operating activities” reaches the three most useful passages without scrolling.
What it means for your money
A share is a claim on a company's future cash, and the 10-K is the one place the company sets out, under signature, how much cash it made, what it owes, what worries it and what its auditor struggled to verify.
The arithmetic a household reader can do without a spreadsheet: operating cash flow divided by net income (here 86%); the largest customer's share of revenue (here 22%); debt due within a year against cash from operations (here $999 million against $102,718 million); and the number of critical audit matters (here one). Write those four down for each holding when the 10-K arrives and compare them with the previous year's four; the comparison, not the level, tells you whether something has changed. To confirm you are reading the latest filing, this method applies.
