What a 10-K actually is
A 10-K is a public company's comprehensive annual report, filed with the U.S. Securities and Exchange Commission, the SEC. It is not the glossy annual report with the photos and the letter from the chief executive. That version is marketing. The 10-K is the legal one, and it is far more detailed, because the SEC requires companies to disclose things they would rather not put in a brochure.
Every 10-K follows the same standard shape: numbered Items grouped into four Parts. That structure is a gift, because it means once you learn where the useful Items sit in one company's filing, you know where they sit in every company's filing. The layout does not change from a tiny industrial to a trillion-dollar tech name.
The sections that matter
Most of the document is boilerplate. A handful of Items do the real work, and these are the ones worth your attention:
- Item 1, Business. What the company actually does: its segments, products, customers, and competition. Read this first if the business is unfamiliar to you.
- Item 1A, Risk Factors. What management says could go wrong. Long and mostly generic, so read it for what is new or changed versus last year. That is where the signal is.
- Item 3, Legal Proceedings. Material lawsuits and regulatory actions that could cost real money.
- Item 7, MD&A. Management's Discussion and Analysis, where management explains the results in plain language. The single most useful narrative section, and the one to read first.
- Item 7A, Market Risk. Exposure to interest rates, currencies, and commodities, quantitative and qualitative.
- Item 8, Financial Statements. The audited income statement, balance sheet, and cash flow statement, plus the footnotes that explain them.
The five-minute read plan
- 1. Skim Item 7 (MD&A) for the story: are revenue and margins rising or falling, and what does management say is driving it.
- 2. Read Item 1A (Risk Factors), focusing on anything new versus last year. Old risks are noise; new risks are the message.
- 3. Jump to Item 8 and check three numbers: the revenue trend, net income, and operating cash flow. Cash flow is harder to fake than earnings.
- 4. Check the balance sheet for debt and liquidity: how much is owed, and can the company cover what is due soon.
- 5. Scan the footnotes for anything that explains an odd number you saw in the statements.
Five steps, five minutes once you have done it a few times. Notice the order: you read the narrative first so you know what to look for in the numbers, then you check the numbers to see whether the narrative holds up. Management writes the words; the auditors sign off on the figures. When the two disagree, believe the figures.
Red flags to watch
A few patterns show up again and again before a story unravels. None is proof of trouble on its own, but any of them is a reason to slow down and read the footnotes carefully:
- Revenue up, cash flow down. Reported sales are growing but cash from operations is not following. Something in how revenue is recognized is doing the heavy lifting.
- Debt climbing faster than the business. Rising leverage with no matching growth in earnings or cash to service it.
- Frequent “one-time” charges. When the same kind of one-time charge appears year after year, it is not one-time, it is the cost of doing business dressed up as an exception.
- An auditor change. A company switching auditors, especially right before a filing, is worth a hard look at why.
- Heavy stock-based compensation. Large amounts of stock pay can flatter reported profit and quietly dilute existing shareholders. Check how big it is relative to net income.
Where to find the filing
Every 10-K is public and free. They all live on the SEC's EDGAR system, and any US-listed company's filings are a search away. WeTradePro's SEC EDGAR lookup pulls any company's filings, its insider Form 4 trades, and its key financials without an account, so you can go from a ticker to the annual report in a couple of clicks and start the five-minute plan straight away.
