How to Read a 10-K

The 10-K is an annual report filed with the SEC. It is dense, lawyered, and the single best source of primary information on a public company.

Start with Item 1 (Business) — how does the company describe itself, its segments, customers, and competition? Item 1A (Risk Factors) is mostly boilerplate, but new or unusually specific risks deserve attention. Item 7 (MD&A) is management's own narrative of results — read between the lines.

Financial statements come in Item 8, followed by footnotes that are often the most valuable section: revenue recognition policies, debt covenants, stock-based compensation, segment data.

A single 10-K rarely tells the full story. Read three to five years to spot trends, language shifts, and changes in tone. What management stops saying can matter as much as what they say.
