A 10-K is the annual report every US public company must file with the SEC: audited, standardized, and written under legal obligation to tell the truth. That last part is why it beats an hour of googling. It is free on the company's investor relations page and at SEC EDGAR (sec.gov/edgar); the 10-Q is its smaller quarterly sibling, and the earnings call is management reading the same story out loud. If your client is private, pull the closest public competitor's filing; the category math is the same.
| where you go | the question it answers for you |
|---|---|
| Item 1 · Business | How does this company actually make money, and through whom? |
| Item 1A · Risk factors | What is management scared of, in writing? Lawyers force candor here; it is the honest part. |
| Item 7 · MD&A (management's discussion and analysis) | How does management explain its own results? Whatever they repeat is what gets funded. |
| Segment results (inside MD&A and the notes) | Where does the growth sit, and where does the money sit? They are often different places. |
| SG&A and the back-page notes | Where is the marketing spend hiding, and how big is it? |
Marketing almost never gets its own line. It sits inside selling, general and administrative expenses (SG&A), rarely labeled, sometimes broken out as an 'advertising costs' note deep in the accounting policies. If the note is not there, estimate: Gartner puts average marketing budgets at 7.7% of company revenue, so revenue times 7.7% gets you inside the right neighborhood. This is the same math the Gartner summary, this week's other reading, teaches you to defend.
Ridgeline Outdoor Group is invented for this page: an outdoor-apparel maker with $2.4 billion in revenue. Here is what ten minutes in its 10-K would hand an account person before a first meeting.
Now the read that makes the ten minutes pay: the fastest-growing third of the business is funded like a side project, because the advertising money is committed to the slower channel. That mismatch is an opportunity, stated in the client's own numbers, and it belongs in your agency's insight card. You found it without a single meeting.
One warning for the AI era: your model will summarize a 10-K fluently and wrongly. It rounds, it blends fiscal years, and it invents segment names. Pull the filing yourself, check every number the model hands you, and treat the difference as the week's real lesson.
