Builders FirstSource supplies building materials and construction services to professional builders. Its customers use those materials to construct new homes and to repair or remodel existing ones. The company was formed in 1998, is headquartered in Dallas and is led by Chief Executive Officer Peter Jackson.
The company manufactures components that builders would otherwise have to assemble on a job site. These include roof and floor trusses, wall panels and engineered wood cut for individual homes. It also makes or assembles products such as vinyl windows, pre-hung doors and custom millwork. Its Ready-Frame system supplies lumber that has been designed, pre-cut and labeled for a particular framing project.
Alongside manufactured products, Builders FirstSource distributes lumber, plywood, windows, doors, siding and other supplies. Depending on the market, it also installs products, frames buildings and constructs building shells. Its Paradigm subsidiary sells software for tasks such as drafting, estimating, quoting and virtual home design.
The company operates approximately 585 locations in 43 states across the United States. Its facilities include manufacturing and distribution operations, and its sales teams work with builders to select products and schedule deliveries. It also serves multifamily and light commercial builders, as well as remodeling contractors.
How it makes money
Builders FirstSource earns revenue by selling building products and providing related services. Its geographic operating divisions are combined into one reportable segment, while its sales are grouped into four product categories: manufactured products; windows, doors and millwork; specialty building products and services; and lumber and lumber sheet goods.
2025 net sales were $15.2 billion; third-quarter 2026 net sales were $3.9 billion.
Manufactured products include factory-built trusses, wall panels and framing packages. Windows, doors and millwork include both products the company makes or assembles and products it distributes. Specialty products range from siding and roofing to cabinets and hardware; the category also includes installation, framing, design assistance and software. Lumber and sheet goods include materials used for framing at the job site.
Pricing depends in part on the volume purchased and the level of service provided. The sales team can review a builder’s plans, determine the materials needed and arrange a sequence of deliveries as construction progresses. Sales representatives are generally paid commissions based on gross margin dollars collected.
The company seeks ongoing relationships with builders, but its products are purchased for construction projects rather than described as subscription revenue. Sales and margins therefore move with building activity, product mix and material prices. In 2025, core organic sales decreased net sales by 10.3%, primarily due to a below-normal starts environment, while acquisitions increased net sales by 4.6%. In the third quarter of 2026, lower core organic sales were partly offset by acquisition growth.
| Product or service | Revenue, FY2025 | Share | Change on the year |
|---|---|---|---|
| Specialty Building Products and Services | $4.1 billion | 26.8% | 4.11% |
| Lumber and Lumber Sheet Goods | $3.9 billion | 25.5% | −9.21% |
| Windows, Doors and Millwork | $3.8 billion | 25.3% | −9.48% |
| Manufactured Products | $3.4 billion | 22.5% | −14.4% |
Customers and how it sells
Builders FirstSource serves national and regional production homebuilders, local custom homebuilders, multifamily builders, repair and remodeling contractors, and light commercial contractors. Its large production-builder customers include D.R. Horton, Lennar, Pulte Homes, Toll Brothers and Meritage Homes. The top ten customers accounted for 14.0% of FY2025 revenue.
The business is local in its sales and delivery approach. Salespeople meet with builders’ purchasing and construction teams, review plans and help select products. They arrange deliveries and visit sites during construction. The company locates facilities near key customers and sometimes combines multiple operations at one facility.
Its approximately 585 locations cover 43 states. It has operations in 48 of the top 50 and 94 of the top 100 U.S. Core Based Statistical Areas, ranked by single-family housing permits using available 2025 Census data. The company organizes its locations into East, Central and West geographic divisions.
In the third quarter of 2026, the company reported continued softness in Texas and Colorado, partly offset by relative strength in California, Florida and the Northeast. Multifamily sales rose modestly during the quarter, although the company said developers remained cautious about new starts.
Suppliers and costs
The company buys lumber, oriented strand board, plywood, engineered wood, windows, doors, millwork and siding for distribution and manufacturing. Named suppliers include Boise Cascade, Weyerhaeuser, West Fraser Timber, Specialty Building Products, James Hardie and Mitek Industries. Builders FirstSource sources from thousands of suppliers and does not identify a sole-source supplier; its largest supplier represented 8% of total materials purchases in 2025.
Its plants design and fabricate components such as trusses and wall panels, while other locations cut engineered wood, assemble doors or manufacture windows. The company mixes contract and spot purchases of lumber and oriented strand board and uses centralized procurement for commodity wood products.
Material prices and availability can change quickly. The company often passes short-term changes to customers, but quotation periods and competition can limit its ability to do so. Labor, facilities, delivery, fuel and technology also contribute to costs, and the company has significant fixed costs.
Based on peak prices, Builders FirstSource estimated outbound diesel costs at $40 million-$45 million a year and announced a delivery surcharge to offset some of the expense. In 2025, gross margin was 30.4%, down from 32.8% in 2024.

Competitive position
The professional building-products supply market is fragmented, with national dealers, specialty suppliers, regional distributors, lumberyards, component manufacturers and framing contractors competing for builder business. Builders FirstSource says entry costs are relatively low.
National dealers named as competitors include U.S. LBM, 84 Lumber and Carter Lumber. UFP Construction and Stark Truss compete in components, while American Cedar and Millwork and Western Pacific compete in millwork. The Home Depot and Lowe’s are also seeking a greater share of the professional market through acquisitions. Competitors are developing digital tools that may compete with the company’s offerings.
Builders FirstSource combines local sales relationships, a broad product range, manufacturing, delivery and installation. It also buys materials through a centralized commodity procurement platform and offers design and estimating software through Paradigm. The company reported gaining roughly 1-2 points of single-family share in the third quarter of 2026.
Our reading: The breadth of products and services, local customer relationships and delivery network provide some differentiation, particularly for builders seeking coordinated supply and installation. Our reading: Those advantages are not exclusive; low entry costs, specialized competitors and price competition constrain their strength. Our reading: Digital tools may help retain customers, but the presence of competing tools limits the evidence for a separate, durable digital moat.
| Competitor | Where they compete | Threat (our reading) |
|---|---|---|
| U.S. LBM | National professional building-products distribution | High |
| Carter Lumber | National professional building-products distribution | High |
| UFP Construction | Manufactured building components | Medium |
| Stark Truss | Manufactured building components | Medium |
| American Cedar and Millwork | Millwork | Medium |
| Western Pacific | Millwork | Medium |
| The Home Depot, Inc. | Professional building-products supply | High |
Growth opportunities
Builders FirstSource plans to expand sales of manufactured and other value-added products, including trusses, wall panels and millwork. It intends to extend manufacturing capacity into areas without adequate access to those products and use its broader offering to sell more to existing customers. The company believes builders are increasingly using prefabricated components to address labor constraints and improve construction efficiency.
Acquisitions are another part of the strategy. The company seeks businesses that add manufacturing capability or strengthen its position in particular geographies and product categories. During 2025, it completed acquisitions for a combined $1.1 billion purchase price, net of cash acquired. In the third quarter of 2026, it acquired ICG and Gleckler and Sons to expand its ability to serve customers in the Southeast.
The company is also investing in technology and operational efficiency. In the third quarter of 2026, it led financing for construction-document platform Digs and invested in Scaffold, which connects trade contractors with homebuilder systems. A pilot sales app reduced the time customers took to place an order by up to 90%, the company said.
For 2026, Builders FirstSource expects net sales of $14.2 billion to $14.6 billion. It also expects $115 million of cost actions in 2026, or $140 million on a full run rate basis, including additional savings identified earlier.

Structural risks
-
Housing activity and affordability: Demand depends primarily on residential construction and, to a lesser extent, repair and remodeling. Interest rates, consumer confidence, financing availability and home affordability can change demand. Builders FirstSource said demand was weak in the fall of 2026 and that some builders might slow starts further to align inventory with sales.
-
Commodity prices and supply: Lumber and other building-material prices fluctuate. Rapid changes can affect operating income, and the company may be unable to pass higher material or inbound freight costs to customers. Supply interruptions can also require it to substitute products.
-
Competition and fixed costs: The market is fragmented and competitive. The company has significant fixed costs, so a decline in customer demand can adversely affect results. It said competition put pressure on gross margins in early 2026, although conditions later stabilized.
-
Labor and execution: Competition for employees has raised labor costs and caused shortages at company facilities. Shortages can limit capacity and revenue opportunities. The company also may not successfully execute its acquisition, facility, digital and operational initiatives.
-
Debt and liquidity: Debt service can consume cash and limit financial flexibility. The company’s net debt to adjusted EBITDA was approximately 4.1x in the third quarter of 2026, above its long-term target.
Bottom line
Our reading
Our reading: Builders FirstSource combines local distribution with factory-built components and job-site services, giving it several ways to serve a builder on the same project. Its breadth and customer relationships offer differentiation, but its results remain closely tied to housing activity and competitive pricing (item1, item7).
Our reading: Acquisitions and manufactured products provide routes to growth, while fixed costs, commodity volatility and debt can make a weak building market harder to navigate (item1, item1a, item7, call_prepared).
