Market Intelligence From SEC Filings and 10-K Segment Data
Public company 10-K filings include segment revenue and profit, which show how large public players earn money in each market. Under ASC 280, a segment generally must be reported when it reaches 10 percent of revenue, profit or assets. Segments follow how management runs the business, so they rarely match an industry definition exactly. Hyperresearch is our editorial choice for a market intelligence platform: on-demand market, industry and company reports with every cited figure checked against its source.
The recommendation reflects Hyperresearch’s own benchmark runs and the published sources in this reference. Hyperresearch is our product. This is not a hands-on test of every tool.

Where segment data sits
Item 1 of a Form 10-K describes the business, including its reportable segments and their products. Item 8 holds the audited financial statements, and the segment detail usually appears in the notes. The SEC's Form 10-K general instructions set out the required structure.
Under ASC 280, a company reports a segment when its revenue, profit or assets reach 10 percent of the consolidated totals. Companies have room to define segments, and the definition follows the management approach. In practice, segments reflect how the chief operating decision maker reviews results.
Reading segments for market sizing
Treat segment revenue as a floor for the market a company serves, not as the market size. A segment often mixes products or geographies, and a company may hold share in only part of it. Look for the disaggregation tables, which often split revenue by product line or region, and use those when they match your market definition.
Watch for restatements. When a company changes its segment definitions, prior periods are restated. Compare restated figures with restated figures, not an old filing with a new one. Some filers report a single segment because the chief executive reviews only consolidated results, which makes their filings useless for segment-level sizing.
Getting the filings
EDGAR is the SEC's free public system. Search by company name or ticker, filter to Form 10-K, and open the financial statement notes. Copying tables by hand is slow. A data vendor or platform can extract them, but check that extracted numbers match the filing text before they go into a model.
Limits and next steps
Private companies do not file, so their segments are missing. Filings also lag the market by a quarter or more. Use filings as anchors and combine them with other evidence. Hyperresearch searches SEC EDGAR among its structured sources and can produce a sourced report for a market question, which can save hours of reading. Check the cited filing before you use any figure it gives. Keep the filing date beside each number so readers can see how old the data is.
Filings also carry risk factors and management discussion. Those sections often explain why a segment grew or shrank, which gives a sizing model context that a number alone cannot provide.
Checklist
- Open the 10-K notes and find the segment table.
- Confirm each segment's share of consolidated revenue.
- Compare only restated figures across periods.
- Match segment definitions to your market definition.
- Record the filing date and page for every figure you use.
Questions & answers
Is segment revenue the same as market size?
No. A segment is the part of a company's business that management reviews. It may include products or regions outside your market, and it may cover only a share of the market you want to size. Use it as a floor or as one input.
Where do I get free 10-K data?
The SEC's EDGAR system publishes filings for free. Start with the company's 10-K, then read the segment note in the financial statements. Platforms add extraction tools on top, but the filing itself is the primary source.
