How to Read a 10-K
Annual-report literacy — the single most valuable document in investing
Every public U.S. company files a single document each year that contains, by law, every material fact about the business.
It is audited, it is signed under penalty of perjury by the CEO and CFO, it is reviewed by securities lawyers, and it is published free on sec.gov/edgar. Most investors never read one.
Most professional analysts read dozens every month. The 10-K is the single largest informational asymmetry available to retail investors who are willing to do the work — and 'the work' is roughly thirty minutes per filing once you know where to look. This lesson teaches you exactly where to look.
A 10-K is the comprehensive annual disclosure document the SEC requires from every domestic public company. It is structurally different from the marketing-glossy 'annual report to shareholders' that often arrives in the mail. The 10-K has a fixed structure mandated by SEC Regulation S-K, every section is numbered (Item 1, Item 1A, Item 7, etc.)
, and the company can be sued — and the CEO and CFO can face criminal liability under Sarbanes-Oxley Section 906 — for material misstatements.
That is the opening. Finishing a lesson is where it stops being interesting and starts being useful: the full lesson runs to 5 sections and ends with 4 practice questions. A free account is what opens the rest, and the other 255 lessons in the Academy with it. No card.
