# Builders FirstSource: Business Model & Revenue Engine



## Direct Answer

Builders FirstSource reports revenue across 4 product and service lines in its fiscal 2025 Form 10-K. Specialty Building Products and Services is the largest, with $4.1 billion of revenue (27% of the total), followed by Lumber and Lumber Sheet Goods at $3.9 billion (26%).

## How Does Builders FirstSource Make Money?

No single line supplies a majority of revenue: the largest, Specialty Building Products and Services, is 27%, which spreads Builders FirstSource's exposure across several demand drivers. Between fiscal 2024 and 2025, Specialty Building Products and Services grew fastest (+4.1%) and Manufactured Products slowest (-14.4%), so the revenue mix tilts toward Specialty Building Products and Services while that gap lasts.

| Product or service | FY2025 revenue | FY2024 revenue | Share of revenue | Change |
| --- | --- | --- | --- | --- |
| Specialty Building Products and Services | $4.1 billion | $3.9 billion | 26.8% | 4.1% |
| Lumber and Lumber Sheet Goods | $3.9 billion | $4.3 billion | 25.5% | -9.2% |
| Windows Doors and Millwork | $3.8 billion | $4.2 billion | 25.3% | -9.5% |
| Manufactured Products | $3.4 billion | $4.0 billion | 22.5% | -14.4% |

## What the Segment Figures Do Not Show

The rows above add up to 100% of Builders FirstSource's reported revenue for fiscal 2025; the difference is intersegment eliminations, corporate revenue or items the company reports outside its segments. Segment definitions are management's choice and change when a company reorganizes, in which case it restates prior years in the next filing, so a multi-year comparison should use the figures from a single filing. Revenue shows where sales come from, not where profit or cash is earned: a small segment can carry most of the margin.

## Where These Numbers Come From

Every figure on this page is a value Builders FirstSource reported in the segment note and revenue disclosures of its Form 10-K filed February 17, 2026 (accession 0001193125-26-054643), read from the SEC's Financial Statement Data Sets. The prior-year column is the comparative figure from that same filing, so it reflects any restatement for a change in segments. Category names are the company's own XBRL labels, lightly reformatted for reading.

Rows that only total other rows (for example a "Products" line beside the individual products) are left out so nothing is counted twice. This page is educational and describes reported history for fiscal 2025; it is not a forecast or a recommendation.
