How to find revenue by business segment

1. Finding it in the 10-K notes

Open the company’s 10-K on EDGAR (sec.gov/edgar/search) and look through the notes for a heading like Segment Information or Segment Reporting — usually toward the back.

Searching the document for `Segment` gets you there quickly. The table lists each segment with revenues, operating income, and assets.

Revenue by geography is usually in the same note (Geographic information), often as a second table beside the segment one.

Quarterly reports carry a condensed version with fewer line items than the annual.

2. The company defines its own segments — the first trap

The rules ask for disclosure along the lines management actually uses to run the business. So segment definitions differ by company, even within the same industry.

One company splits by product, another by region, another by customer type. That is why segments from two companies rarely line up side by side.

⚠️ Definitions also change between years. A reorganisation redraws the segments and prior figures are restated to match. If the same segment shows different numbers in an old filing and a new one, this is usually why.

3. When the segments do not add up to total revenue

Add the segments and the total often differs from company revenue. Three reasons cover most cases.

Intersegment sales: one segment selling to another counts in each segment but cancels at the company level, shown as a line like `Intersegment eliminations`.

What was left out: `Corporate`, `Other`, or `Unallocated` holds head-office costs and minor activities.

Table units: the header states whether figures are `in millions` or `in thousands`.

⚠️ So reconciling the total first is step one with any segment table. When it does not reconcile, the footnote beneath usually says which of the three is responsible.

4. What you end up looking at

Weight: which segment is the body of the company. Where one dominates, that segment’s conditions are the company’s conditions.

Change: which segments grew or shrank against the same period last year. Flat total revenue can hide one rising and one falling.

Segment margin: the largest segment by revenue is often not the largest by profit. A smaller segment with a high operating margin can produce most of the earnings.

5. Reading it on Stocklore

The segment revenue section on a stock’s detail shows the latest quarter’s mix and the change against last year. Segment names appear as filed.

⚠️ Some stocks are not shown. We check the segment total against reported company revenue and show only what reconciles. Companies where intersegment sales are folded in, or where the table is structured unusually, are marked as not yet available — rather than showing a figure we cannot verify.

Where it reconciles, the trend by segment is shown too (how each segment moved quarter by quarter).

What to keep in mind

• Segments are the company’s own construct. The rules ask for management’s view, not a standard taxonomy, so two companies rarely divide the same way.
• Annual and quarterly differ in detail. The 10-Q version is condensed and may omit assets or geography.
• Segment profit reflects how the company allocated costs. How much head-office expense lands on each segment is also the company’s choice, and it moves segment margins.
• This page is information, not investment advice. That a segment grew or shrank is a disclosed fact; what happens next is not in the filing.
