OVERVIEW

We are a leading supplier and manufacturer of building materials, manufactured components and construction services to professional homebuilders, sub-contractors, remodelers and consumers. The Company operates approximately 570 locations in 43 states across the United States (“U.S.”), which are internally organized into geographic operating divisions. Due to the similar economic characteristics, categories of products, distribution methods and customers, our operating divisions are aggregated into one reportable segment.

We offer an integrated solution to our customers by providing manufacturing, supply and installation of a full range of structural and related building products. Our manufactured products include our factory-built roof and floor trusses, wall panels, vinyl windows, custom millwork and trim, as well as engineered wood that we design, cut, and assemble specifically for each home. We also assemble interior and exterior doors into pre-hung units. Additionally, we supply our customers with a broad offering of professional grade building products not manufactured by us, such as dimensional lumber and lumber sheet goods and various window, door and millwork lines along with other specialty building products. Our full range of construction-related services include professional installation, turn-key framing and shell construction, spanning all of our product categories. Further, through our Paradigm subsidiary, we offer software solutions and services for the building products industry.

Builders FirstSource, Inc. is a Delaware corporation formed in 1998 as BSL Holdings, Inc. On October 13, 1999, our name changed to Builders FirstSource, Inc. Our common stock trades on the New York Stock Exchange (“NYSE”) under the symbol “BLDR”.

OUR INDUSTRY

We operate in the professional segment (“Pro Segment”) of the U.S. residential building products supply market. Customers in the Pro Segment primarily include production and custom homebuilders, remodeling contractors, and multifamily builders. The industry remains highly fragmented with competition from large national dealers, specialty dealers, large building supply retailers, regional and local material distributors and smaller privately owned suppliers, truss manufacturers and lumberyards. As such, the industry presents significant opportunities for growth and attractive acquisition opportunities.

The residential building products industry is driven by the level of activity in both the U.S. residential new construction market and the U.S. residential repair and remodeling market. Growth within these markets is linked to a number of key factors, including demographic trends, housing demand, interest rates, employment levels, availability of credit, foreclosure rates, consumer confidence, the availability of qualified tradesmen, and the state of the economy in general.

The residential building products industry is characterized by several key trends, including greater utilization of manufactured components, an expanding role of the distributor in providing turn-key services and a consolidation of suppliers by homebuilders, as described in more detail below. Additionally, there is increasing interest in using digital tools to help drive end-to-end efficiencies throughout the construction industry.

Prefabricated components: Compared to conventional “stick-build” construction where builders cut and assemble lumber at the job site with their own labor, prefabricated components are engineered in an offsite location using specialized equipment and labor. This outsourced task allows for optimal material usage, lower overall labor costs and improved quality of structural elements. In addition, using prefabricated components typically results in faster construction because fabrication can be automated and performed more systematically. As such, we believe there is a long-term trend towards increased use of prefabricated components by homebuilders.

Turn-key services: Many homebuilders have taken a more limited role in the homebuilding process and have outsourced certain key elements of the construction process, including process management, product selection, order input, scheduling, framing and installation. As such, we believe that many homebuilders are increasingly looking to suppliers in the Pro Segment to perform these critical functions, resulting in greater demand for integrated project services.

Consolidation of suppliers by homebuilders: We believe that homebuilders are increasingly looking to consolidate their supplier base. Many homebuilders are seeking a more strategic relationship with suppliers that are able to offer a broad range of products and services and, as a result, are allocating a greater share of wallet to a select number of larger, full-service suppliers.

According to the U.S. Census Bureau, the single-family residential construction market was an estimated $392.1 billion in 2023, which was 13.5% lower than 2022. Further, according to the Home Improvement Research Institute (“HIRI”) in its September 2023 semi-annual forecast, the professional repair and remodel end market was an estimated $167.8 billion in 2023, which was 5.0% lower than 2022.

OUR CUSTOMERS

We serve a broad customer base across the U.S. We have a diverse geographic footprint, as we have operations in 48 of the top 50 and 89 of the top 100 U.S. Metropolitan Statistical Areas (“MSAs”), as ranked by single family housing permits based on available 2023 U.S. Census data. Given the local nature of our business, we have historically and will continue to locate our facilities in close proximity to our key customers and co-locate multiple operations in one facility to improve efficiency.

We have a diversified customer base, ranging from large production builders to small custom homebuilders, as well as multifamily builders, repair and remodeling contractors and light commercial contractors. For the year ended December 31, 2023, our top 10 customers accounted for 14.7% of net sales, with our largest customer accounting for 4.5% of net sales. Our top 10 customers are comprised primarily of the largest national production homebuilders, including publicly traded companies such as D.R. Horton, Inc., Dream Finders Homes, Inc., Lennar Corporation, Pulte Homes, Inc., Taylor Morrison Home Corporation, and Toll Brothers Inc.

In addition to the largest production homebuilders, we also service and supply regional production and local custom homebuilders as well as repair and remodeling contractors and multifamily builders. These customers require high levels of service and a broad product offering. Our sales team expects to work very closely with the designers on a day-to-day basis in order to ensure the appropriate products are identified, ordered or produced and delivered on time to the building site. To account for these increased service costs, pricing in the industry is tied to the level of service provided and the volumes purchased. Servicing a broad range of homebuilders, including single-family and multifamily builders, and remodeling contractors allows us to more effectively manage market conditions that may have an outsized adverse impact on a specific customer segment.

OUR PRODUCTS AND SERVICES

We group our building products and services into four product categories:

Lumber and Lumber Sheet Goods. Lumber and lumber sheet goods include dimensional lumber, plywood and oriented strand board (“OSB”) products used in on-site house framing. The products in this category are highly sensitive to fluctuations in market prices for such commodities.

Manufactured Products. Manufactured products are factory-built substitutes for job-site framing and include wood floor and roof trusses, wall panels, and engineered wood that we design, cut, and assemble for each home. Manufactured products also include our proprietary whole-house framing solution, Ready-Frame®, which designs, pre-cuts, labels, and bundles lumber into customized framing packages, saving builders both time and money and improving job-site safety. Our manufactured products allow builders to

build higher quality homes more efficiently. Roof trusses, floor trusses, and wall panels are built in a factory-controlled environment. Engineered floors and beams are cut to the required size and packaged for the given application at many of our locations. Without manufactured products, builders construct these items on-site, where weather and variable labor quality can negatively impact construction cost, quality and installation time. In addition, engineered wood beams have greater structural strength than conventional framing materials, allowing builders to frame houses with more open space creating a wider variety of house designs. Engineered wood floors and open-web floor trusses are also stronger and straighter than conventionally framed floors. While not as sensitive to commodity price fluctuations as lumber and lumber sheet goods, the products in this category are constructed using lumber and lumber sheet goods, and thus are somewhat sensitive to commodity price fluctuations.

Windows, Doors and Millwork. Windows and doors are comprised of the manufacturing, assembly and distribution of windows, and the assembly and distribution of interior and exterior door units. We manufacture a portion of the vinyl windows that we distribute in our plant in Houston, Texas which allows us to supply builders, primarily in the Texas market, with cost-competitive products. Our pre-hung interior and exterior doors consist of a door slab with hinges and door jambs attached, reducing on-site installation time and providing higher quality finished door units than those constructed on-site. These products typically require a high degree of product knowledge and training to sell. Millwork includes interior trim and custom features, including those that we manufacture under the Synboard ® brand name. Synboard is produced from extruded PVC and offers several advantages over traditional wood features, such as greater durability and no ongoing maintenance, such as periodic caulking and painting.

Specialty Building Products and Services. Specialty building products and services consist of various products, including vinyl, composite and wood siding, exterior trim, metal studs, cement, roofing, insulation, wallboard, ceilings, cabinets and hardware. This category also includes services such as turn-key framing, shell construction, design assistance and professional installation of products spanning all of our product categories. We provide professional installation and turn-key services as a solution for our homebuilder customers. Through our installation services program, we help homebuilders realize efficiencies through improved scheduling, resulting in reduced cycle time and better cost controls. By utilizing an energy efficiency software program, we also assist homebuilders in designing energy efficient homes in order to meet increasingly stringent energy rating requirements. Upgrading to our premium windows, doors, and insulating products can reduce overall cost to the homebuilder by minimizing costs of the required heating/cooling system. We work closely with the homebuilder to select the appropriate mix of our products to meet current and forthcoming energy codes. We believe these services require scale, capital and sophistication that smaller competitors do not possess. We also offer software products through our Paradigm subsidiary, including drafting, estimating, quoting, and virtual home design services, which provide software solutions to retailers, distributors, manufacturers and homebuilders that help them boost sales, reduce costs, and become more competitive. We believe that the homebuilding and remodeling industries are increasingly adopting digital solutions and that we are well-positioned to take advantage of these trends because of our scale and continuous investments in digital technologies through our Paradigm business.

We compete in a highly competitive and fragmented marketplace. We believe our integrated approach and scale allow us to compete effectively through our comprehensive product lines, prefabricated components and value-added services, combined with the knowledge of our integrated sales forces to enable our homebuilder customers to complete construction more quickly, with higher quality and at a lower cost. While we expect these benefits to be particularly valuable to our customers in market environments characterized by labor shortages and sourcing challenges, we expect such benefits will also be increasingly valued and demanded by our customers operating under normal market conditions.

MANUFACTURING

Our manufacturing facilities utilize industry leading technology, including automated robotic truss lines, and high-quality materials to improve product quality, increase efficiency, reduce lead times and minimize production errors. We manufacture products within two of our product categories: manufactured products, and windows, doors & millwork.

Manufactured Products — Trusses and Wall Panels. Truss and wall panel production has two steps — design and fabrication. Each house requires its own set of designed shop drawings, which vary by builder type — production versus custom builders. Production builders use prototype house plans as they replicate houses. These house plans may be minimally modified to suit individual customer demand. We maintain an electronic master file of trusses and wall panels for each builder’s prototype houses. For custom builders, the components are designed individually for each house. We download the shop drawings from our design department to computerized saws. We assemble the cut lumber to form roof trusses, floor trusses or wall panels, before shipping the finished components by house to the job site. In addition, we offer our Ready-Frame® framing system which uses specialty software to calculate project-specific lumber needs to provide pre-cut and labeled packages delivered and ready to assemble on the jobsite.

Manufactured Products — Engineered Wood. As with trusses and wall panels, engineered wood components have design and fabrication steps. We design engineered wood floors using a master filing system similar to the truss and wall panel system. Engineered wood beams are designed to ensure the beam will be structurally sound in the given application. After the design phase, a

printed layout is generated. We use this layout to cut the engineered wood to the required length and assemble all of the components into a house package. We design and fabricate engineered wood at many of our distribution locations.

Custom Millwork. Our manufactured custom millwork consists primarily of interior and exterior pre-hung door systems, intricate interior and exterior mouldings, custom and premium windows, finish hardware, stair parts, mantels and columns units.

Windows. We manufacture a full line of traditional vinyl windows at an approximately 200,000 square foot manufacturing facility located in Houston, Texas. The process begins by purchasing vinyl lineal extrusions. We cut these extrusions to size and join them together to form the window frame and sash. We then purchase sheet glass and cut it to size. We combine two pieces of identically shaped glass with a sealing compound to create a glass unit with improved insulating capability. We then insert the sealed glass unit and glaze it into the window frame and sash. The unit is completed when we install a balance to operate the window and add a lock to secure the window in a closed position.

Pre-hung Doors. We manufacture pre-hung interior and exterior doors at many of our locations. We insert door slabs and pre-cut door jambs into a door machine, which bores holes into the doors for the door hardware and applies the jambs and hinges to the door slab. We then apply the casing that frames interior doors at a separate station. Exterior doors do not have a casing, and instead may have sidelights applied to the sides of the door, a transom attached over the top of the door unit and a door sill applied to the threshold.

OUR STRATEGY

By pursuing the Company’s clear strategic pillars as outlined below, we intend to build on our advantaged market position to create value for our shareholders by increasing profits and net cash flow generation, while making us a more valuable partner to our customers. The resulting cash flow should provide meaningful opportunities for increased investment in organic and acquisitive growth that preserve our balance sheet strength, grow our return on invested capital and return capital to our shareholders.

Organic Growth of Value-add Products and Services

Maximize our share of wallet by capturing above-market growth in our higher margin value-added products. We believe our national manufacturing footprint and differentiated capabilities will allow us to capture growth in our higher margin value-added products, including trusses, wall panels and millwork. We believe our value-added products address the growing demand for ways to build homes more efficiently, addressing labor constraints and rising costs. We plan to accelerate this growth by further expanding our national manufacturing footprint to serve locations that do not currently have adequate access to these higher margin products. By focusing on our differentiated platform and broad product mix, we are able to offer a complete array of products and services that would otherwise need to be sourced from various distributors, providing us an opportunity to capture a greater share of wallet. This operational platform often will make us a preferred distributor for large-scale national homebuilders as well as local and custom homebuilders looking for more efficient ways to build a home. We have also made significant investments in digital solutions that we believe position us to take advantage of long-term digitization trends in the homebuilding and remodel industries. We believe that customers continue to place an increased value on these capabilities, which further differentiates us from our competitors.

Leverage our competitive strengths to capitalize on housing market share**.** We intend to leverage our core business strengths including local market presence, national footprint, unmatched scale in manufacturing capability, breadth of product portfolio, and end market exposure to expand our sales and profit margins. Our customers continue to emphasize the importance of local access, competitive pricing, a broad product portfolio, sales force knowledge, labor-saving manufactured products, on-site services and overall “ease of use” with their building products suppliers. Our comprehensive product offering, experienced sales force, strong strategic vendor relationships, location coverage in important markets, and tenured senior management team position us well to capitalize on demand in the new home construction market and the repair and remodel segment. Our large delivery fleet, professional drivers, well-positioned locations, and comprehensive inventory management enable us to provide “just-in-time” product delivery, ensuring a smoother and faster production cycle for the homebuilder. Our comprehensive network of products, services and facilities provides a strategically advantaged service model which enhances our value to our customers and provides a strong platform to drive growth. We have also expanded our operational footprint in the multifamily and light commercial markets to position us for further growth in these end markets.

Invest in Innovation and Drive Operational Excellence

Optimize our highly scalable cost structure with operational excellence initiatives**.** We continue to focus on standardizing and automating processes and technology-based workflows to minimize costs, streamline our operations and enhance working capital efficiency. We are implementing operational excellence initiatives that are designed to further improve efficiency, as well as customer service. These initiatives, including distribution and logistics, pricing and margin management, back-office efficiencies, customer integration and systems-enabled process improvements, should yield significant cost savings. The scope and scale of our existing

infrastructure, customer base, and logistical capabilities mean that improvements in efficiency, when replicated across our network, can yield substantial profit margin expansion.

Continue to Build our High-Performing Culture

Strong emphasis on putting our people first. Our team members are a critical resource, and every single one makes a difference. Enhancing talent acquisition, employee development and retention will ensure we continue to attract and retain this valuable component of our business. Our team members are the face of the Company to our customers and the communities in which we operate. Their contributions in serving our customers are a fundamental component in our success. We care about our team members and strive to have a strong environmental, health and safety program that drives world-class safety results and ensures our team members leave their workplace safely, every day. We have developed programs to help progress our people’s careers, such as our all-encompassing learning platform, 1-Team University, and we strive to maintain a performance-based culture.

Environmental, social and governance strategy. We are also committed to making informed choices that improve our corporate governance, financial strength, operational efficiency, environmental stewardship, community engagement and resource management. Consistent with our core values, our goal is to be recognized by our customers as the preferred supplier, by our employees as a safe, diverse and inclusive workforce, by the industry as being at the forefront of innovation, by our stakeholders as an ethical company and by the communities in which we serve as a good corporate citizen. We recognize that the environmental sustainability of our products is important to both us as a company and to our customers. We prioritize purchasing and supplying sustainable wood products led by the Sustainable Forestry Initiative. Helping homebuilders become more productive, more efficient and safer is fundamental to what we do, and we are passionate about building this future together.

Disciplined Capital Allocation

Pursue strategic acquisitions. The highly fragmented nature of the Pro Segment of the U.S. residential new construction building products supply market presents substantial acquisition opportunities. Our long-term acquisition strategy is focused on pursuing potential acquisitions that present opportunities to add manufacturing capabilities in a relatively short period of time, or that provide opportunities to advance our position in desirable geographies and enhance our market strength in key products. We believe that our proven operating model can be successfully adapted to these markets and where homebuilders, many of whom we currently serve elsewhere, would value our broad product and service offering, professional expertise, and superior customer service. When entering a new market, our strategy is to acquire market-leading distributors and subsequently expand their product offerings or add manufacturing facilities while integrating their operations into our centralized platform. This strategy allows us to quickly achieve the scale required to maximize profitability and leverage existing customer relationships in the local market. Our management has shown the capability to effectively and efficiently integrate newly-acquired businesses, increase productivity, and drive value. We have successfully integrated over 60 acquisitions since 1998, including the company-transforming BMC and ProBuild transactions.

Consistent capital allocation priorities. In addition to our acquisition strategy, we continue to focus on disciplined capital allocation to drive value creation. We actively monitor our working capital to align our needs with market demand signals and the size of our top-line. Additionally, our focus remains on maintaining a strong balance sheet, with a low net leverage ratio, providing multiple paths for capital deployment, including returning excess capital to shareholders through opportunistic share repurchases at an attractive long-term cost basis.

SALES AND MARKETING

We seek to attract and retain customers through exceptional customer service, leading product quality, broad product and service offerings, and competitive pricing. This strategy is centered on building and maintaining strong customer relationships rather than traditional marketing and advertising. We strive to add value for the homebuilders through shorter lead times, lower total project costs, faster project completion and higher quality. We believe by executing this strategy we will continue to generate new business.

Our experienced, locally focused sales force is at the core of our sales effort. This sales effort involves deploying salespeople who are skilled in housing construction to meet with a homebuilder’s construction superintendent, local purchasing agent, or local executive with the goal of becoming their primary product supplier. If selected by the homebuilder, the salesperson and his or her team review blueprints for the contracted homes and advise the homebuilder in areas, such as opportunities for cost reduction, increased energy efficiencies, and regional aesthetic preferences. Next, the team determines the specific package of products that are needed to complete the project and schedules a sequence of site deliveries. Our large delivery fleet and comprehensive inventory management systems enable us to provide “just-in-time” product delivery, ensuring a smoother and faster production cycle for the homebuilder. Throughout the construction process, the salesperson makes frequent site visits to ensure timely delivery and proper installation, and to make suggestions for efficiency improvements. We believe this level of service is highly valued by our customers and generates significant customer loyalty. At December 31, 2023, we employed approximately 2,500 sales representatives, who are

generally paid a commission based on gross margin dollars collected and worked with approximately 2,700 sales coordinators and product specialists.

MATERIALS AND SUPPLIER RELATIONSHIPS

We purchase inventory primarily for distribution, some of which is also utilized in our manufacturing plants. The key materials we purchase include dimensional lumber, OSB and plywood, engineered wood, windows, doors, millwork, and siding. Our largest suppliers are national companies such as Boise Cascade Company, Weyerhaeuser Company, West Fraser Timber Co. Ltd., Specialty Building Products, James Hardie Industries plc, and Louisiana-Pacific Corp. We believe marketplace supply allows us to competitively source most of our requirements without reliance on any particular supplier and that our diversity of suppliers affords us purchasing flexibility. Due to our centralized procurement platform for commodity wood products and corporate oversight of purchasing programs, we believe we are able to maximize the advantages of both our and our suppliers’ broad geographic footprints and negotiate purchases across multiple markets to achieve more favorable contracts with respect to price, terms of sale, and supply. Additionally, for certain customers, we institute purchasing programs on commodity wood products, such as OSB and lumber to align portions of our procurement costs with our customer pricing commitments. We balance our OSB and lumber purchases with a mix of contract and spot market purchases to ensure consistent supply of product necessary to fulfill customer contracts, to source products at the lowest possible cost, and to minimize our exposure to the volatility of commodity lumber prices.

We currently source products from thousands of suppliers in order to reduce our dependence on any single company and to maximize purchasing leverage. While our largest single supplier only represented 8.3% of our total materials purchases for the year ended December 31, 2023, we believe we are one of the largest customers for many suppliers, and therefore have significant purchasing leverage. We have found that using multiple suppliers ensures a stable source of products and the best purchasing terms as the suppliers compete to gain and maintain our business.

We maintain strong relationships with our suppliers, and we believe opportunities exist to improve purchasing terms in the future, including inventory storage or “just-in-time” delivery to reduce our inventory carrying costs. We will continue to pursue additional procurement cost savings which would further enhance our margins and cash flow.

COMPETITION

We have and will continue to experience robust competition for homebuilder business due to the highly fragmented nature of the Pro Segment and the relatively low costs of entry into the market. We face competition from other large national dealers that focus on the Pro Segment, including U.S. LBM, 84 Lumber and Carter Lumber; specialty dealers, such as roofing building supply companies; regional and local building supplies dealers; single and multi-site lumber yards; framing contractors; component manufacturers, including Universal Forest Products and Stark Truss; and millwork operators, such as American Cedar and Millwork, and Western Pacific. We believe that we have competitive advantages over our competitors due to our long-standing customer relationships, local market knowledge, competitive pricing, superior service, broad product offering and large-scale procurement capabilities. We cultivate long-term relationships with professional builders and work to retain our customers by delivering a full range of high-quality products on time, and offering trade credit, competitive pricing and integrated service and product packages, such as turn-key framing and shell construction, as well as manufactured components and installation. We believe that our local market knowledge, strong customer relationships, superior service, and operational efficiencies allow us to cost-effectively supply our customers, which both enhances profitability and reduces the risk of losing customers to competitors.

HUMAN CAPITAL

At December 31, 2023, we had approximately 29,000 employees. Less than 1% of employees are covered by collective bargaining agreements, and we believe we have generally good relations with these labor unions. Employee levels are managed to align with the pace of business and management believes it has sufficient human capital to operate its business successfully.

Our people are the key to our success, and our continued focus on delivering exceptional customer service and innovative solutions. In managing our human capital, our goal is to ensure team member safety, growth and development in an inclusive and team-based environment. By participating in regular surveys and focus groups, we place a strong emphasis on enhancing and increasing the retention and engagement level of our team members. Key areas of the Company’s human capital focus include the following:

Workplace Health and Safety

We care about our team members and anyone who enters our workplace. We strive to have a strong environmental, health and safety program that focuses on implementing policies and training programs. We also perform self-audits to ensure our team members leave their workplace safely, every day. Over the past several years, we have developed and implemented programs designed to promote workplace safety, with the goal of reducing the frequency and severity of employee injuries. We review and monitor our performance closely by updating our executive team monthly on progress.

During 2023, our experience and continuing focus on workplace safety enabled us to preserve business continuity without sacrificing our commitment to keeping our team members and workplace visitors safe.

The Company also aspires to reduce its lost time and recordable injuries each year. In 2023, we reduced our Total Recordable Incident Rate for the eighth consecutive year and by 32% over the prior year.

We also broadly provide accessible safety training to our employees in a number of formats to accommodate the learner’s style, pace, location, and access to technology.

Respectful and Inclusive Culture

Our team members are the face of the Company to our customers and the communities in which we operate. Their contributions in serving our customers are a fundamental component in our success, and every single team member makes a difference.

Our Company strives to foster a culture that encourages collaboration, flexibility and fairness to enable all team members to contribute to their full potential. We are committed to enhancing our efforts to promote a respectful and inclusive environment across all aspects of our organization, including hiring, promotion and developmental opportunities. To further these efforts, we conduct both in-person and online training through our online learning management system. We continue to create greater awareness, eliminate unconscious bias and foster more open and honest communication through our Corporate Inclusion Council.

The Company’s employee survey to assess and improve our efforts finds that the majority of employees feel welcome, safe and included, treated fairly with opportunities to reach full potential, supported professionally, emotionally and socially and are comfortable sharing experiences and opinions, and valued as a team member. We’ve identified four key priorities through our surveys: enhance awareness, broaden workforce representation, improve communication, and increase inclusion and engagement. With these priorities in mind, we host quarterly town halls and engage in regular Company-wide communications, offer leadership development opportunities and sales trainings, and continue to establish regional and local employee resource groups.

Learning and Development

In order to attract and retain top talent, we provide several resources in a variety of formats that promote the ongoing learning and development of our team members. We offer leadership development training for new and existing leaders in topics such as: Effective Communication, Conducting Performance Management, Developing Successful and Productive Teams, Conflict Resolution and Management, Providing Exceptional Customer Service, Hiring for Fit and Building a Diverse and Inclusive Team. We have maintained our commitment to learning and development through our online learning management system and limited on-site courses facilitated in a safe setting by our training and development team. Our online course catalog offers approximately 15,000 courses which are available to all team members.

INFORMATION TECHNOLOGY SYSTEMS

Our operations are dependent upon our information technology systems, which encompass all of our major business functions. Our primary enterprise resource planning (“ERP”) systems, which we currently use for operations representing the majority of our sales, are proprietary systems that have been highly customized by our computer programmers. The materials required for thousands of standard builder plans are stored by the system for rapid quoting or order entry. Hundreds of price lists are maintained on hundreds of thousands of SKUs, facilitating rapid price changes in a changing product cost environment. A customer’s order can be tracked at each stage of the process and billing can be customized to reduce a customer’s administrative costs and payment speed.

We have a customized financial reporting system that consolidates financial, sales and workforce data from our ERP systems and our human resource information system (“HRIS”), delivering standardized enterprise key performance indicators. This technology platform provides management with robust corporate and location level performance management by leveraging standardized metrics and analytics allowing us to plan, track and report performance and compensation measures.

We have developed a proprietary program for use in our component plants. This software reviews product designs for errors, schedules the plants and provides the data used to measure plant efficiency. In addition, we have purchased several software products that have been integrated with our primary ERP system. These programs assist in various aspects of our business, such as analyzing blueprints, generating material lists, purchasing lumber products at the lowest cost, delivery management, resource planning and scheduling, and financial planning and analysis.

In 2022, we announced the decision to move the Company to a new ERP system. The program began in 2023, with detailed planning and design efforts. We expect the program to require continued design, build and testing followed by several years of deployment across our broad network of operating sites. As part of this program, we intend to utilize technology-enabled opportunities to enhance our operating model and transform our business creating further value for all our stakeholders.

SEASONALITY AND OTHER FACTORS

Our first and fourth quarters have historically been, and are generally expected to continue to be, adversely affected by weather causing reduced construction activity during these quarters. Quarterly results historically have reflected, and are expected to continue to reflect, fluctuations from period to period arising from the following:

The volatility of lumber prices;

The cyclical nature of the homebuilding industry;

General economic conditions in the markets in which we compete;

The pricing policies of our competitors;

Disruptions in our supply chain;

The production schedules of our customers; and

The effects of weather.

The composition and level of working capital typically change during periods of increasing sales as we carry more inventory and receivables. Working capital levels typically increase in the first and second quarters of the year due to higher sales during the peak residential construction season. These increases may result in negative operating cash flows during this peak season, which historically have been financed through available cash and borrowing availability under credit facilities. Generally, collection of receivables and reduction in inventory levels following the peak building and construction season positively impact cash flow.

Risks associated with our business, any investment in our securities, and with achieving the forward-looking statements contained in this report or in our news releases, websites, public filings, investor and analyst conferences or elsewhere, include the risk factors described below. Additional risks and uncertainties not presently known to us or that we currently deem immaterial may also impair our business operations. Any of these risks, whether known or unknown, could cause our actual results to differ materially from expectations and could have a material adverse effect on our business, financial condition or results of operations, and we may not succeed in addressing these challenges and risks. You should read these Risk Factors in conjunction with “Management’s

Discussion and Analysis of Financial Condition and Results of Operations” in Item 7 and our consolidated financial statements and related notes in Item 8.

Industry Risks

The industry in which we operate is dependent upon the residential homebuilding industry, as well as the U.S. economy, the credit markets and other important factors.

The building products industry is highly dependent on new home and multifamily construction as well as repair and remodel, which in turn are dependent upon a number of factors, including interest rates, consumer confidence, employment rates, foreclosure rates, housing inventory levels and occupancy, housing demand and the health of the U.S. economy and mortgage markets. Unfavorable changes in demographics, credit markets, including rising mortgage and other interest rates, consumer confidence, household incomes, inflation, housing affordability, or housing inventory levels and occupancy, or a weakening of the U.S. economy or of any regional or local economy in which we operate could adversely affect consumer spending, result in decreased demand for our products, and adversely affect our business. Production of new homes and multifamily buildings may also decline because of shortages of qualified tradesmen, reliance on inadequately capitalized builders and sub-contractors, shortages of suitable building lots and material, and lack of financing or more expensive financing available to homebuilders. In addition, the building industry is subject to various local, state, and federal statutes, ordinances, and regulations concerning zoning, building design and safety, construction, energy and water conservation and similar matters, including regulations that impose restrictive zoning and density requirements in order to limit the number of homes that can be built within the boundaries of a particular area or in order to maintain certain areas as primarily or exclusively residential. Regulatory restrictions may increase our operating expenses and limit the availability of suitable building lots for our customers, which could negatively affect our sales and earnings. Because we have substantial fixed costs, relatively modest declines in our customers’ production levels could have a significant adverse effect on our financial condition, operating results and cash flows.

The building supply industry is subject to cyclical market pressures.

Prices of building products are subject to fluctuations arising from changes in supply and demand, national and international economic conditions, including inflation and interest rates, labor costs, competition, market speculation, government regulation, and trade policies, as well as from periodic delays in the delivery of lumber and other products. The prices of wood products directly affect our sales and earnings. In particular, low prices for wood products over a sustained period can adversely affect our financial condition, operating results and cash flows, as can excessive spikes in prices. If lumber or structural panel prices were to significantly decline from current levels, our sales and profits would be negatively affected as compared to 2023 operating results. Our lumber and lumber sheet goods product category represented 24.1% of total net sales for the year ended December 31, 2023. We have limited ability to manage the timing and amount of pricing changes for building products. In addition, the supply of building products fluctuates based on available manufacturing capacity. A shortage of capacity or excess capacity in the industry can result in significant increases or declines in prices for those building products, often within a short period of time. Such price fluctuations can adversely affect our financial condition, operating results and cash flows.

In addition, the building products industry is cyclical in nature. An economic downturn in the homebuilding industry could have an adverse effect on our operating results, financial condition or cash flows. We are not able to predict the timing, severity or duration of any future downturns in the housing market.

Our industry is highly fragmented and competitive, and increased competitive pressure may adversely affect our results.

The building products supply industry is highly fragmented and competitive. We face, and will continue to face, significant competition from local, regional and other national building materials chains, as well as from privately-owned single site enterprises and new entrants into the market, due to the relatively low barrier to, and cost of, entry. Any of these competitors may (1) foresee the course of market development more accurately than we do, (2) develop products that are superior to our products, (3) have the ability to produce or supply similar products at a lower cost, (4) develop stronger relationships with local homebuilders or commercial builders or (5) adapt more quickly to new technologies or evolving customer requirements than we do. As a result, we may not be able to compete successfully with them. In addition, home center retailers, which have historically concentrated their sales efforts on retail consumers and small contractors, have intensified their marketing efforts, including expanding e-commerce offerings, to professional homebuilders in recent years and may continue to intensify these efforts in the future. Furthermore, certain product manufacturers sell and distribute their products directly to production homebuilders or commercial builders, and the volume of such direct sales could increase in the future. Additionally, manufacturers of products distributed by us may elect to sell and distribute directly to homebuilders or commercial builders in the future or enter into exclusive supplier arrangements with other distributors. Consolidation of production homebuilders or commercial builders may result in increased competition for their business. Finally, we may not be able

to maintain our operating costs or product prices at a level sufficiently low for us to compete effectively. If we are unable to compete effectively, our financial condition, operating results and cash flows may be adversely affected.

Homebuyer demand may shift towards smaller homes creating fluctuations in demand for our products.

Home affordability can be a key driver in demand for our products and home prices have increased meaningfully over the past several years. Home affordability is influenced by a number of economic factors, such as the level of employment, consumer confidence, consumer income, supply of houses, the availability of financing and interest rates. Changes in the inventory of available homes as well as economic factors relative to home prices may result in homes becoming less affordable. Furthermore, consumer preferences could shift to smaller or larger homes in the future. This could cause homebuyer demand to soften or shift substantially which could have an adverse impact on our financial condition, operating results and cash flows if we are unable to respond to the new market demands effectively.

A range of factors may make our quarterly revenues, earnings and cash flows variable.

Risk Management and Strategy

The Company maintains robust and comprehensive processes, procedures and controls to protect and secure its information systems and data infrastructure from cybersecurity threats. The Company’s cybersecurity program is led by its Chief Information Security Officer (“CISO”). The Company’s cybersecurity program interfaces with other functional areas within the Company, including but not limited to the Company’s business segments and information technology, legal, risk management, human resources and internal audit departments, as well as external third-party partners, to identify and understand potential cybersecurity threats. The Company regularly assesses and updates its processes, procedures and management techniques in light of ongoing cybersecurity developments.

Internally, the CISO coordinates oversight of reviewing security alerts, identifying and monitoring ongoing and potential cybersecurity threats, evaluating strategic business impacts of cybersecurity threats and developing programs and initiatives to educate the Company’s employees regarding cybersecurity. The CISO also manages the Company’s Security Incident Response Plan (the “Incident Response Plan”), which outlines action steps for the preparation, identification, triage, analysis, containment, eradication, recovery and reflection stages of a cybersecurity incident. The Incident Response Plan serves as the charter for the Company’s Security Incident Response Team (the “Incident Response Team”), which includes a strategic team comprised of executives from various cross-functional management teams, as well as a tactical team comprised of internal technical support roles and external third-party service providers. The Incident Response Plan provides how the Incident Response Team will analyze and, as necessary, escalate cybersecurity incidents both internally and with third-party service providers based on type and severity of the specific incident.

The Company also requires cybersecurity training for all active employees, focusing on the appropriate protection and security of confidential company and third-party information. Additionally, the Company provides quarterly cybersecurity awareness training that covers a broad range of security topics, including secure access practice, phishing schemes, remote work and response to suspicious activities. In addition to online training, employees are educated through several methods, including event-triggered awareness campaigns, recognition programs, security presentations, company intranet articles, videos, system-generated communications, email publications and various simulation exercises.

The Company has engaged a third-party managed detection and response company to monitor the security of its information systems around-the-clock, including intrusion detection, and to provide instantaneous alerting should a cybersecurity event occur. The Company also maintains a cybersecurity insurance policy and has engaged a third-party digital forensics and incident response consultant and legal counsel on retainer.

The Company does not believe that any risks from cybersecurity threats, nor any previous cybersecurity incidents, have materially affected the Company. However, the sophistication of cyber threats continues to increase, and the preventative actions the Company has taken and continues to take to reduce the risk of cyber incidents and protect its systems and information may not successfully protect against all cyber incidents. For more information on how cybersecurity risk may materially affect the Company’s business strategy, results of operations, or financial condition, please refer to Item 1A Risk Factors.

Governance

The Company’s Audit Committee and Board of Directors provide ultimate oversight of the Company’s cybersecurity risk management. The Audit Committee regularly reviews and discusses with management the strategies, processes, procedures and controls pertaining to the management of the Company’s information technology operations, including cyber risks and cybersecurity. The Company’s Chief Information Officer (“CIO”) provides quarterly reports to the Audit Committee regarding the evolving cybersecurity risk landscape, including emerging risks, as well as the Company’s processes, program and initiatives for managing these risks.

The Company’s CISO reports directly to the CIO, who in turn reports to the CFO. The CISO maintains the certified information systems security professional (CISSP) certification and GIAC G2700 (Certified ISO 27000 Specialist) and has over 20 years of

experience in cybersecurity. Under the direction of the CISO, the Company’s cybersecurity department continuously analyzes cybersecurity and resiliency risks to our business, considers industry trends and implements controls, as appropriate, to mitigate these risks. The team consists of cybersecurity professionals holding multiple certifications such as the CISSP, CEH (Certified Ethical Hacker), GSOM (GIAC Security Operations Manager), GCIA (GIAC Certified Intrusion Analyst), GCFA (GIAC Certified Forensic Analyst), GNFA (GIAC Network Forensic Analyst), GCTI (GIAC Cyber Threat Intelligence), CISM (Certified Information Security Manager) and CISA (Certified Information Systems Auditor). This analysis drives the Company’s long- and short-term cybersecurity strategies, which are executed through a collaborative effort within the IT department and are communicated to the Board of Directors regularly.

I****tem 2. Properties

We have a broad network of distribution and manufacturing facilities in 43 states throughout the U.S. Based on available 2023 U.S. Census data, we have operations in 48 of the top 50 and 89 of the top 100 U.S. Metropolitan Statistical Areas, as ranked by single family housing permits in 2023.

Distribution centers typically include 10 to 15 acres of outside storage, a 45,000 square foot warehouse, 4,000 square feet of office space, and 15,000 square feet of covered storage. The outside area provides space for lumber storage and a staging area for delivery while the warehouse stores millwork, windows and doors, and other specialty building products. The distribution centers are usually located in industrial areas with low cost real estate and easy access to freeways to maximize distribution efficiency and convenience. Many of our distribution centers are situated on rail lines for efficient receipt of goods.

Our manufacturing facilities produce trusses, wall panels, engineered wood, windows, pre-hung doors and custom millwork. Where efficient, they are located on the same premises as our distribution facilities. Truss and panel manufacturing facilities vary in size from 30,000 square feet to 60,000 square feet with eight to 10 acres of outside storage for lumber and for finished goods. Our window manufacturing facility in Houston, Texas is approximately 200,000 square feet.

We own 153 actively operating facilities and contractually lease 418 actively operating facilities. These leases typically have an initial lease term of five to 15 years and most provide options to renew for specified periods of time. A majority of our leases provide for fixed annual rentals. Certain of our leases include provisions for escalating rent, as an example, based on changes in the consumer price index. Most of the leases require us to pay taxes, insurance and common area maintenance expenses associated with the properties. As described in Note 9 to the consolidated financial statements included in Item 8 of this annual report on Form 10-K, 115 of our leased facilities are subject to a sales-lease back transaction that is accounted for in our financial statements as owned assets with offsetting financing obligations.

In addition, we operate a fleet of approximately 18,800 rolling stock units which includes trucks, forklifts, and trailers used to deliver products from our distribution and manufacturing centers to our customers’ job sites. Through our emphasis on local market flexibility and strategically placed locations, we minimize shipping and freight costs while maintaining a high degree of local market expertise. Through knowledge of local homebuilder needs, customer coordination and rapid restocking ability, we reduce working capital requirements and guard against out-of-stock products. We believe that this reliability is highly valued by our customers and reinforces customer relationships.

I****tem 3. Legal Proceedings

The Company has a number of known and threatened construction defect legal claims. While these claims are generally covered under the Company’s existing insurance programs to the extent any loss exceeds the deductible, there is a reasonable possibility of loss that is not able to be estimated at this time because (i) many of the proceedings are in the discovery stage, (ii) the outcome of future litigation is uncertain, and/or (iii) the complex nature of the claims. Although the Company cannot estimate a reasonable range of loss based on currently available information, the resolution of these matters could have a material adverse effect on the Company's financial position, results of operations or cash flows.

In addition, we are involved in various other claims and lawsuits incidental to the conduct of our business in the ordinary course. We carry insurance coverage in such amounts in excess of our self-insured retention as we believe to be reasonable under the circumstances and that may or may not cover any or all of our liabilities in respect of such claims and lawsuits. Although the ultimate disposition of these other proceedings cannot be predicted with certainty, management believes the outcome of any such claims that are pending or threatened, either individually or on a combined basis, will not have a material adverse effect on our consolidated financial position, cash flows or results of operations. However, there can be no assurances that future adverse judgments and costs would not be material to our results of operations or liquidity for a particular period.

Although our business and facilities are subject to federal, state and local environmental regulation, environmental regulation does not have a material impact on our operations. We believe that our facilities are in material compliance with such laws and regulations. As owners and lessees of real property, we can be held liable for the investigation or remediation of contamination on such properties, in some circumstances without regard to whether we knew of or were responsible for such contamination. Our current expenditures with respect to environmental investigation and remediation at our facilities are minimal, although no assurance can be provided that more significant remediation may not be required in the future as a result of spills or releases of petroleum products or hazardous substances or the discovery of unknown environmental conditions.

OVERVIEW

We are a leading supplier and manufacturer of building materials, manufactured components and construction services to professional contractors, sub-contractors and consumers. The Company operates approximately 570 locations in 43 states across the U.S. Given the span and depth of our geographical reach, our locations are organized into three geographical divisions (East, Central, and West), which are also our operating segments. All of our segments have similar customers, products and services, and distribution methods. Due to the similar economic characteristics, categories of products, distribution methods and customers, our operating segments are aggregated into one reportable segment.

We offer an integrated solution to our customers by providing manufacturing, supply, and installation of a full range of structural and related building products. Our manufactured products include our factory-built roof and floor trusses, wall panels, vinyl windows, custom millwork and trim, as well as engineered wood that we design, cut, and assemble for each home. We also assemble interior and exterior doors into pre-hung units. Additionally, we supply our customers with a broad offering of professional grade building products not manufactured by us, such as dimensional lumber and lumber sheet goods, various window, door and millwork lines along with other various building products. Our full range of construction-related services includes professional installation, turn-key framing and shell construction, and spans all of our product categories.

We group our building products into four product categories:

Lumber and Lumber Sheet Goods. Lumber and lumber sheet goods include dimensional lumber, plywood, and OSB products used in on-site house framing.

Manufactured Products. Manufactured products consist of wood floor and roof trusses, wall panels, and engineered wood.

Windows, Doors and Millwork. Windows and doors are comprised of the manufacturing, assembly, and distribution of windows and the assembly and distribution of interior and exterior door units. Millwork includes interior trim and custom features that we manufacture, such as intricate mouldings, stair parts, and columns.

Specialty Building Products and Services. Specialty building products and services consist of various products, including vinyl, composite and wood siding, exterior trim, metal studs, cement, roofing, insulation, wallboard, ceilings, cabinets, and hardware. This category also includes services such as turn-key framing, shell construction, design assistance and professional installation of products spanning all of our product categories. We also offer software products through our Paradigm subsidiary, including drafting, estimating, quoting, and virtual home design services, which provide software solutions to retailers, distributors, manufacturers and homebuilders that help them boost sales, reduce costs, and become more competitive.

Our operating results are dependent on the following trends, strategies, events and uncertainties, some of which are beyond our control:

Homebuilding Industry and Market Competition. Our business is driven primarily by the residential new construction market and the residential repair and remodel market, which are in turn dependent upon a number of factors, including demographic trends, interest rates, consumer confidence, employment rates, housing affordability, household formation, land development costs, the availability of skilled construction labor, rising inflationary pressures, mortgage markets and the health of the economy. Many factors have impacted and may continue to impact our sales and gross margins, including continued consolidation within the building products supply industry, increased competition for homebuilder business, supply chain constraints and cyclical fluctuations in commodity prices. Moreover, our industry remains highly fragmented and competitive, and we will continue to face significant competition from local and regional suppliers. As various current market dynamics, including inflationary pressures, mortgage rate increases and shifts in housing affordability improve, industry forecasters, including the National Association of Home Builders (“NAHB”), expect to see housing demand increase in the near-term. Despite recent tempered market conditions, we believe the housing industry remains underbuilt and that there are several meaningful trends that indicate U.S. housing demand will continue to be strong over the long-term, including the aging of housing stock and normal population growth due to immigration and birthrate exceeding death rate.

Targeting Large Production Homebuilders. The homebuilding industry continues to undergo consolidation, and the larger homebuilders continue to increase their market share. We expect that trend to continue as larger homebuilders have better liquidity and land positions relative to the smaller, less capitalized homebuilders. Our focus is on maintaining relationships and market share with these customers while balancing the competitive pressures we face in servicing large homebuilders with certain profitability expectations. Additionally, we have been successful in expanding our custom homebuilder base while maintaining acceptable credit standards.

Repair and remodel end market. While influenced by housing starts to a lesser degree than the homebuilding market, the repair and remodel market is still dependent upon some of the same factors, including demographic trends, interest rates, consumer confidence, employment rates, the health of the economy and home financing markets. As a result of these pressures, we may experience reduced sales demand, challenges in the supply chain, increased margin pressures and/or increased operating costs in this area of our business. We expect that our ability to remain competitive in this space will depend on our continued ability to provide a high level of customer service coupled with a broad product offering.

Use of Prefabricated Components. Homebuilders are increasingly using prefabricated components in order to realize increased efficiency, overcome skilled construction labor shortages and improve quality. Shortening cycle time from start to completion is a key imperative of the homebuilders during periods of strong consumer demand. As the availability of skilled construction labor remains limited, we continue to see the demand for prefabricated components increasing within the residential new construction market.

Economic Conditions. Economic changes both nationally and locally in our markets impact our financial performance. The building products supply industry is highly dependent upon new home construction and, to a lesser extent, repair and remodel activities, and is subject to cyclical market changes. Our operations are subject to fluctuations arising from changes in supply and demand, national and local economic conditions, labor costs and availability, competition, government regulation, trade policies, rising inflation and other factors that affect the homebuilding industry, such as demographic trends, increasing interest rates, housing starts, the high cost of land development, employment levels, consumer confidence, and the availability of credit to homebuilders, contractors, and homeowners. Disruptions and uncertainties as a result of a number of unforeseen environmental, social, economic or other factors, may have a significant impact on our future operating results.

Housing Affordability. The affordability of housing can be a key driver in demand for our products. Home affordability is influenced by a number of economic factors, such as the level of employment, consumer confidence, consumer income, supply of houses, the availability of financing and interest rates. Changes in the inventory of available homes and other economic factors relative to home prices could result in changes to the affordability of homes. As a result, homebuyer demand may shift toward smaller or larger homes creating fluctuations in demand for our products.

Cost and/or Availability of Materials. Prices of building materials, including wood products, are subject to cyclical market fluctuations, which may adversely impact operating income when prices rapidly rise or fall within a relatively short period of time. We purchase materials which are then sold to customers as well as used as direct production inputs for our manufactured and prefabricated products. Short-term changes in the cost and/or availability of these materials, some of which are subject to significant fluctuations, are often passed on to our customers, but our pricing quotation periods and market competition may limit our ability to pass on such price changes. We may also be limited in our ability to pass on increases on in-bound freight costs on our products. We may also experience challenges sourcing suitable products for our customers and may be forced to provide alternative materials as substitution for contracted orders. Our inability to pass on material price increases to our customers could adversely impact our operating results.

Controlling Expenses. Another important aspect of our strategy is controlling costs and striving to be a low total-cost building materials supplier in the markets we serve. We closely manage our working capital and operating expenses, and we pay careful attention to our logistics function and its effect on our shipping and handling costs. However, we do have significant fixed costs and declines in our customer demand could have an adverse impact on our operating results.

Multifamily and Light Commercial Business. Our primary focus has been on single-family residential new construction and the repair and remodel end market. However, through recent acquisitions we have expanded our operational footprint in the multifamily market, predominantly five-story and smaller, wood construction, and the light commercial market, growing our value-add components and millwork product offerings in this end market. We will continue to identify opportunities for profitable growth in these areas.

Capital Structure. We strive to optimize our capital structure to ensure that our financial needs are met in light of economic conditions, business activities, organic investments, opportunities for growth through acquisition and the overall risk characteristics of our underlying assets. In addition to these factors, we also evaluate our capital structure on the basis of our leverage ratio, our liquidity position, our debt maturity profile, our market capitalization, and market interest rates. As such, we may enter into various debt or equity transactions to appropriately manage and optimize our capital structure and liquidity needs.

RECENT DEVELOPMENTS

Business Combinations

During 2023 we completed a number of acquisitions for a combined $252.5 million purchase price, net of cash acquired, including the acquisitions of (i) Noltex Truss and its affiliates (“Noltex”), (ii) Builders Millwork and Supply, Inc. (“BMS”) (iii) J.B. Millworks, LLC (“JBM”), (iv) Church and Church, Inc. (“Church’s”), (v) Franks Cash and Carry, Inc. (“FCC”), (vi) Standale Lumber, LLC and Granville Lumber Co., LLC (“Standale”), and (vii) Encore Performance, LLC (“Encore”).

These acquisitions further expand our market footprint and provide additional operations in our value-add product categories and our multifamily customer segment and are further described in Note 3 to the consolidated financial statements included in Item 8 of this annual report on Form 10-K.

Company Shares Repurchases

Under share repurchase programs authorized by the board of directors since August 2021, the Company has repurchased a total of 87.1 million shares of common stock, or 42.2% of the Company’s total shares outstanding, at an average price of $70.27, inclusive of fees and taxes, including 17.8 million shares of common stock at an average price of $100.49, inclusive of fees and taxes, in 2023. As of December 31, 2023, the Company had $200.5 million authorization remaining under its current share repurchase program.

On February 21, 2024, the Company’s Board of Directors authorized the repurchase of up to $1.0 billion of the Company’s outstanding shares of common stock, inclusive of the approximately $200 million remaining outstanding in the prior share repurchase plan authorized in April 2023.

Debt Transactions

On January 17 and April 3, 2023, the Company amended the Revolving facility to extend the maturity to January 17, 2028, and to include additional pricing tiers for the applicable margin.

These transactions are described further in Note 8 to the consolidated financial statements included in Item 8 of this annual report on Form 10-K. Collectively, these transactions have extended our debt maturity. From time to time, based on market conditions and other factors and subject to compliance with applicable laws and regulations, the Company may repurchase or call our notes, repay debt, repurchase shares of our common stock or otherwise enter into transactions regarding its capital structure.

CURRENT OPERATING CONDITIONS AND OUTLOOK

According to the U.S. Census Bureau, actual U.S. total housing starts for the year ended December 31, 2023, were 1.4 million, a decrease of 9.0% compared to the year ended December 31, 2022. Actual U.S. single-family housing starts for the year ended December 31, 2023, were 0.9 million, a decrease of 6.0% compared to the year ended December 31, 2022. A composite of third-party sources, including the NAHB, are forecasting 1.4 million U.S. total housing starts and 1.0 million U.S. single-family housing starts for 2024, which is relatively flat and an increase of 4.7%, respectively, from 2023. In addition, in its September 2023 semi-annual forecast, the Home Improvement Research Institute (“HIRI”) forecasted sales in the professional repair and remodel end market to increase 1.3% in 2024 compared to 2023.

We believe the long-term outlook for the housing industry is positive and that the housing industry remains underbuilt due to growth in the underlying demographics compared to historical new construction levels. However, uncertainty around interest rates and inflation may continue to dampen near-term housing industry demand as homes are less affordable for consumers, investors and builders. We believe we are well-positioned to take advantage of the construction activity in our markets and to increase our market share, which may include strategic acquisitions. We will continue to focus on working capital by closely monitoring the credit exposure of our customers, remaining focused on maintaining the right level of inventory and by working with our vendors to improve payment terms. We strive to achieve the appropriate balance of short-term expense control while maintaining the expertise and capacity to grow the business as market conditions expand.

RESULTS OF OPERATIONS

A discussion regarding our financial condition and results of operations for the year ended December 31, 2023, compared to the year ended December 31, 2022, is presented below. A discussion regarding our financial condition and results of operations for the year ended December 31, 2022, compared to the year ended December 31, 2021, can be found under Item 7 of Part II of our Annual Report on Form 10-K for the fiscal year ended December 31, 2022, filed with the SEC on February 28, 2023.

2023 Compared with 2022

The following table sets forth the percentage relationship to net sales of certain costs, expenses and income items for the years ended December 31:

Net Sales. Net sales for the year ended December 31, 2023, were $17.1 billion, a 24.8% decrease from net sales of $22.7 billion for 2022. Net sales decreased primarily as a result of a core organic sales decrease of 17.3% and a commodity price deflation decrease of 11.1%, partially offset by sales growth from acquisitions of 3.6%.

The following table shows net sales classified by major product category for the years ended December 31:

We experienced decreased net sales in all of our product categories primarily due to a slow-down in single-family housing starts throughout the year, resulting in a decline in core organic sales, and commodity price deflation.

Gross Margin. Gross margin decreased $1.7 billion to $6.0 billion due to decreased sales. Our gross margin percentage increased to 35.2% in 2023 from 34.1% in 2022, a 1.1% increase. This increase was attributable to an improved product mix toward our value-add products, including recent strategic investments in multifamily value-add operations.

Selling, General and Administrative Expenses. Selling, general and administrative expenses decreased $0.1 billion, or 3.5%. This decrease in expenses was primarily due to decreased variable compensation costs related to decreased sales and profitability, and reduced expense related to customer reserves, partially offset by additional operating expenses from locations acquired within the last twelve months.

As a percentage of net sales, selling, general and administrative expenses increased to 22.4% from 17.5% in 2022. This increase was primarily due to decreased cost leverage on lower net sales during the period.

Interest Expense, Net. Interest expense, net was $192.1 million in 2023, a decrease of $6.3 million from 2022. Interest expense decreased primarily due to the $27.4 million loss on extinguishment recognized in 2022, partially offset by higher debt balances and average interest rates in 2023 compared to 2022.

Income Tax Expense. We recorded income tax expense of $443.6 million during the year ended December 31, 2023, compared to income tax expense of $822.5 million during the year ended December 31, 2022, a decrease of $378.9 million, driven by a decrease in income before income taxes in the current period. Our effective tax rate was 22.4% in 2023 and 23.0% in 2022. Our effective tax rate was favorably affected in 2023 by the impact of federal and state tax credits on decreased tax expense.

LIQUIDITY AND CAPITAL RESOURCES

Our primary capital requirements are to fund working capital needs and operating expenses, meet required interest and principal payments, and to fund capital expenditures and potential future growth opportunities. Our capital resources at December 31, 2023, consist of cash on hand and borrowing availability under our Revolving facility.

Our Revolving facility will be primarily used for working capital, general corporate purposes, and funding capital expenditures and growth opportunities. In addition, we may use the Revolving facility to assist debt consolidation. Availability under the Revolving facility is determined by a borrowing base. Our borrowing base consists of trade accounts receivable, inventory, other receivables which include progress billings and credit card receivables, and qualified cash that all meet specific criteria contained within the credit agreement, minus agent specified reserves. Net excess borrowing availability is equal to the maximum borrowing amount minus outstanding borrowings and letters of credit.

The following table shows our borrowing base and excess availability as of December 31, 2023, and 2022:

As of December 31, 2023, we had $464.0 million in outstanding borrowings under our Revolving facility and our net excess borrowing availability was $1.3 billion after being reduced by outstanding letters of credit of $70.3 million. Excess availability must

equal or exceed a minimum specified amount, currently $180.0 million, or we are required to meet a fixed charge coverage ratio of 1:00 to 1:00. We were not in violation of any covenants or restrictions imposed by any of our debt agreements at December 31, 2023.

Liquidity

Our liquidity at December 31, 2023, was $1.3 billion, which consists of net borrowing availability under the Revolving facility and cash on hand.

Our level of indebtedness results in significant interest expense and could have the effect of, among other things, reducing our flexibility to respond to changing business and economic conditions. From time to time, based on market conditions and other factors and subject to compliance with applicable laws and regulations, the Company may repurchase or call our notes, repay debt, or otherwise enter into transactions regarding its capital structure.

Should the current industry conditions deteriorate or we pursue additional acquisitions, we may be required to raise additional funds through the sale of capital stock or debt in the public capital markets or in privately negotiated transactions. There can be no assurance that any of these financing options would be available on favorable terms, if at all. Alternatives to help supplement our liquidity position could include, but are not limited to, idling or permanently closing additional facilities, adjusting our headcount in response to current business conditions, attempts to renegotiate leases, managing our working capital and/or divesting of non-core businesses. There are no assurances that these steps would prove successful or materially improve our liquidity position.

Consolidated Cash Flows

A discussion regarding our consolidated cash flows for the year ended December 31, 2023, compared to the year ended December 31, 2022, is presented below. A discussion regarding our consolidated cash flows for the year ended December 31, 2022, compared to the year ended December 31, 2021, can be found under Item 7 of Part II of our Annual Report on Form 10-K filed with the SEC on February 28, 2023.

2023 Compared with 2022

Cash provided by operating activities was $2.3 billion in 2023 compared to cash provided by operating activities of $3.6 billion in 2022. The decrease in cash provided by operating activities was largely the result of a decrease in net income in 2023 of $1.2 billion.

For the year ended December 31, 2023, compared to the prior year ended December 31, 2022, the Company used cash to invest $0.3 billion less, primarily due to $0.4 billion less spent on acquisitions, offset by $0.1 billion more as a net investment in property, plant and equipment.

Cash used in financing activities was $1.7 billion in 2023 which consisted primarily of $1.8 billion in repurchases of common stock, partially offset by $0.2 billion in net borrowings on the Revolving facility. Cash used in financing activities was $2.6 billion for 2022 which consisted primarily of $2.6 billion in repurchases of common stock, $0.6 billion to redeem the outstanding 6.75% senior secured notes due 2027 (“2027 notes”), and net paydowns on the Revolving facility of $0.3 billion, offset by net proceeds from the issuance of $0.7 billion of 6.375% senior unsecured notes due 2032 (“6.375% 2032 notes”) and the issuance $0.3 billion of 4.25% senior unsecured notes due 2032 (“4.25% 2032 notes,” and together with the 6.375% 2032 notes, the “2032 notes”).

These transactions are described in Note 8 to the consolidated financial statements included in Item 8 of this annual report on Form 10-K.

Capital Expenditures

Capital expenditures vary depending on prevailing business factors, including current and anticipated market conditions. Historically, capital expenditures have, for the most part, remained at relatively low levels in comparison to the operating cash flows generated during the corresponding periods. We expect our 2024 capital expenditures to be in the range of $400 million to $500 million primarily related to rolling stock, equipment and facility expansion and improvements to support our operations.

CRITICAL ACCOUNTING POLICIES AND ESTIMATES

Critical accounting policies are those that both are important to the accurate portrayal of a company’s financial condition and results, and require subjective or complex judgments, often as a result of the need to make estimates about the effect of matters that are inherently uncertain.

In order to prepare financial statements that conform to generally accepted accounting principles (“GAAP”), we make estimates and assumptions that affect the amounts reported in our financial statements and accompanying notes. Certain estimates are particularly sensitive due to their significance to the financial statements and the possibility that future events may be significantly different from our expectations.

We have identified the following accounting policy that requires us to make the most subjective or complex judgments in order to fairly present our consolidated financial position and results of operations.

Goodwill

Goodwill represents the excess of the amount we paid to acquire businesses over the estimated fair value of tangible assets and identifiable intangible assets acquired, less liabilities assumed. At December 31, 2023, our goodwill balance was $3.6 billion, representing 33.9% of our total assets.

We test goodwill for impairment in the fourth quarter of each year or at any other time when impairment indicators exist. Examples of such indicators that could cause us to test goodwill for impairment between annual tests, include a significant change in the business climate, unexpected competition or a significant deterioration in market share. We may also consider market capitalization relative to our net assets. Housing starts are a significant sales driver for us. If there is a significant decline or an expected decline in housing starts, this could adversely affect our expectations for a reporting unit and the value of that reporting unit.

The process of evaluating goodwill for impairment involves the determination of the fair value of our reporting units. Our reporting units are aligned with our three geographical divisions which are also determined to be our operating segments. In evaluating goodwill for impairment, the Company first assesses qualitative factors to determine whether it is more likely than not that the fair value of the reporting unit is less than its carrying amount. If we conclude that it is more likely than not that the fair value of the reporting unit is not less than its carrying amount, then no further testing of the goodwill is required.

However, if we determine that it is more likely than not that the fair value of the reporting unit is less than its carrying amount, we perform a quantitative goodwill impairment test. This test identifies both the existence of and the amount of goodwill impairment by comparing the fair value of a reporting unit to its carrying amount, including goodwill. If the fair value of a reporting unit exceeds its carrying amount, goodwill is not impaired. If the carrying amount of a reporting unit exceeds its fair value, an impairment loss is recognized in an amount equal to that excess, limited to the amount of goodwill allocated to that reporting unit.

We assessed our goodwill balance at December 31, 2023, using a quantitative assessment. In performing the quantitative impairment test at December 31, 2023, we developed the fair value using a discounted cash flow methodology. Inherent in such fair value determinations are significant assumptions relating to future cash flows, expected future revenues, expected future profitability, the discount rate, the terminal value, and our interpretation of current economic indicators and market conditions and their impact on our strategic plans and operations. Due to the uncertainties associated with such estimates, interpretations and assumptions, actual results could differ from projected results, which could result in impairment of goodwill being recorded.

Significant information and assumptions utilized in estimating future cash flows for quantitative goodwill impairment analyses include projections of revenue growth utilizing publicly available industry information such as lumber commodity prices and housing start forecasts developed by industry forecasters, including the NAHB. Expected future profitability reflects current headcount levels and cost structure and are flexed in future years based upon historical trends at various revenue levels. Long-term growth was based on terminal value earnings before interest, taxes, depreciation and amortization (“EBITDA”) multiples to reflect the relevant expected acquisition prices. The discount rate used is intended to reflect the weighted average cost of capital for a potential market participant and includes all risks of ownership and the associated risks of realizing the stream of projected future cash flows. Decreasing the long-term growth EBITDA multiple or increasing the discount rate would not have changed the results of our impairment testing.

At December 31, 2023, the fair values of each of our reporting units were substantially in excess of their respective carrying amounts. Factors that could negatively impact the estimated fair value of our reporting units and potentially trigger impairment include, but are not limited to, unexpected competition, lower than expected housing starts, an increase in market participant weighted average cost of capital, increases in material or labor cost, and/or significant declines in our market capitalization. Future impairment of goodwill would have the effect of decreasing our earnings or increasing our losses in such period but would not impact our current

outstanding debt obligations or compliance with covenants contained in the related debt agreements. We did not have any goodwill impairments in 2023, 2022 or 2021.

RECENTLY ISSUED ACCOUNTING STANDARDS

Information regarding recent accounting pronouncements is discussed in Note 2 to the consolidated financial statements included in Item 8 of this annual report on Form 10-K.

I****tem 7A. Quantitative and Qualitative Disclosures about Market Risk

We may experience changes in interest expense if changes in our debt occur. Changes in market interest rates could also affect our interest expense. Our 5.00% unsecured senior notes due 2030 (“2030 notes”), 4.25% 2032 notes, and 6.375% 2032 notes bear interest at a fixed rate, and therefore our interest expense related to these notes would not be affected by an increase in market interest rates. Borrowings under the Revolving facility bear interest at either a base rate or secured overnight financing rate (“SOFR”), plus, in each case, an applicable margin. A 1.0% increase in interest rates on the Revolving facility would result in $4.6 million in additional interest expense annually based on our $464.0 million in outstanding borrowings as of December 31, 2023. The Revolving facility also assesses variable commitment and outstanding letter of credit fees based on quarterly average loan utilization.

We purchase certain materials, including lumber products, which are then sold to customers as well as used as direct production inputs for our manufactured products that we deliver. Short-term changes in the cost of these materials and the related in-bound freight costs, some of which are subject to significant fluctuations, are sometimes, but not always, passed on to our customers. Delays in our ability to pass on material price increases to our customers can adversely impact our operating results.

INDEX TO CONSOLIDATED FINANCIAL STATEMENTS

Report of Independent Registered Public Accounting Firm

To the Board of Directors and Stockholders of Builders FirstSource, Inc.

Opinions on the Financial Statements and Internal Control over Financial Reporting

We have audited the accompanying consolidated balance sheets of Builders FirstSource, Inc. and its subsidiaries (the “Company”) as of December 31, 2023 and 2022, and the related consolidated statements of operations, of changes in stockholders' equity and of cash flows for each of the three years in the period ended December 31, 2023, including the related notes (collectively referred to as the “consolidated financial statements”). We also have audited the Company's internal control over financial reporting as of December 31, 2023, based on criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO).

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of the Company as of December 31, 2023 and 2022, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2023 in conformity with accounting principles generally accepted in the United States of America. Also in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2023, based on criteria established in Internal Control - Integrated Framework (2013) issued by the COSO.

Basis for Opinions

The Company's management is responsible for these consolidated financial statements, for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting, included in Management’s Report on Internal Control over Financial Reporting appearing under Item 9A. Our responsibility is to express opinions on the Company’s consolidated financial statements and on the Company's internal control over financial reporting based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud, and whether effective internal control over financial reporting was maintained in all material respects.

Our audits of the consolidated financial statements included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions.

Definition and Limitations of Internal Control over Financial Reporting

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Critical Audit Matters

The critical audit matter communicated below is a matter arising from the current period audit of the consolidated financial statements that was communicated or required to be communicated to the audit committee and that (i) relates to accounts or disclosures that are material to the consolidated financial statements and (ii) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates.

Revenue Recognition – Distribution Sales

As described in Note 2 to the consolidated financial statements, the Company recognized consolidated net sales of $17.1 billion for the year ended December 31, 2023, a majority of which pertains to distribution sales. Revenue is recognized as performance obligations are satisfied by transferring control of a promised good or service to a customer in an amount that reflects the consideration we expect to be entitled to in exchange for those goods or services. Distribution sales typically consist of the sale of building products the Company manufactures and the resale of purchased building products. The Company recognizes revenue related to distribution sales at a point in time upon delivery of the ordered goods to their customers. Payment terms related to distribution sales are not significant as payment is generally received shortly after the point of sale.

The principal consideration for our determination that performing procedures relating to revenue recogni
