 Item 1. Business.

 Our Company
 Cornerstone Building Brands, Inc. ("Cornerstone Building Brands", together with its subsidiaries, unless the context requires otherwise, the "Company," "we," "us" or "our") is a holding company incorporated in the State of Delaware. We are a leading manufacturer of exterior building products in North America by sales and serve residential and commercial customers across both the new construction and repair and remodel markets.

 Our operations are organized as three reportable segments: Aperture Solutions, Surface Solutions and Shelter Solutions. We have:
 • One of the broadest product offerings in our industry. Our total addressable market is diverse and expands across multiple geographies, end markets, channels and customers providing us with significant benefits.
 • A leading market position in various North American markets we serve, including, among others, vinyl windows, vinyl siding, stone veneer installations, metal accessories, metal roofing and wall systems and engineered metal building systems.
 • An extensive coast-to-coast network of manufacturing, distribution and branch office facilities throughout North America.
 • A vertically integrated manufacturing process that enables us to deliver better service and positions us to be a cost-advantaged manufacturer.

 Our Business Strategy and Operating Model
 Building our leading business and brand positions in attractive growth and return categories. We have leading brands that we believe have sustainable competitive advantages in the North American markets we serve. Our brands and core value proposition are meaningful to our customers and the consumers they serve in their respective categories.

 Build on Cornerstone Building Brands customer-centric culture and sales excellence. We have a long track record of developing and maintaining deep and lasting channel partnerships. Our customers look to us not only for our product quality, performance, and breath of our product offering, but for our service and responsiveness. We have the opportunity to grow organically and to lead in price by continuing to build on our customer-centric culture and amplifying differentiation through top-tier service and quality, as well as new product development. Using a highly collaborative selling approach, we intend to grow in attractive, highly fragmented market sectors that demand superior service and value the reliability and energy efficiency offered by our products.

 Revitalizing our operating model. Our business segments are organized based on distinct product categories and each segment's management is responsible for the business segment's strategy and bottom-line performance. While our business units operate with a certain degree of independence, they are built on a consistent and unifying framework of operating principles that we believe is critical to our strategic growth and margin improvement across our entire business. The framework builds on executing on operational, sales and growth excellence strategies.

 We are focused on simplifying our business through rationalizing our brands and systems, as well as our manufacturing and warehouse footprint. We are delivering on creating more efficient and cost-effective processes by investing in automation; driving procurement savings; improving labor planning and productivity; as well as other improvements that leverage our scale to strengthen our business.

 We believe our framework allows each of our business units to take advantage of available opportunities for revenue growth, pricing excellence and margin improvement. We believe this work will enable us achieve organic growth above market and to earn superior returns in the long-term.

 Driving value through talent. The Company has built a diverse and talented leadership team that is well-positioned to execute on our transformation to a more aligned operating model. We believe that investing in our employees is a critical component of our business strategy. We endeavor to do this through talent acquisition, development, succession planning and fostering an inclusive workforce.

 Enhancing returns and deploying our cash flow to high return opportunities. We continue to believe that investing in profitable, organic growth initiatives is our most attractive opportunity. We are intently focused on adhering to a disciplined capital allocation framework, which includes: (i) investing in our core business through capital expenditures and other organic growth initiatives, and (ii) pursuing strategic acquisitions to broaden our portfolio and capabilities across the residential and commercial markets, with a focus on adjacent exterior building products and related services. As part of this framework, we may also restructure, reposition or divest non-core product lines or assets.

 We focus our core business investments on high-return initiatives in large markets to build scale and drive efficiency and investments in growing markets that leverage our operational and distribution channel capabilities.

 Acquisitions and divestitures. We regularly evaluate opportunities that best support our long-term strategy, including acquisitions and divestitures.

 We have a history of making strategic acquisitions that meet strict criteria. We frequently engage in negotiations with potential sellers regarding the possible purchase of businesses or assets that are strategic and complementary to our existing operations. Such negotiations may include participation in public auctions involving a number of potential buyers or situations where we are the only party or one of a very limited number of potential buyers.

 We also evaluate possible dispositions of assets or businesses when such investments are no longer core to our operations and do not fit into our long-term strategy.

 Reportable Segments
 We have three reportable segments: Aperture Solutions, Surface Solutions and Shelter Solutions. Our reportable segments compete based on aesthetics, quality, price, service, product performance, breadth of product offerings and responsiveness to distributor, retailer and installer needs, as well as end-user customer preference. Our markets are very competitive. For the year ended December 31, 2024, our top 10 customers accounted for 38% of net sales, with one customer accounting for 12% of our net sales. See Note 18 — Reportable Segment and Geographical Information in the Notes to the Consolidated Financial Statements for information on our reportable segments.
 Our Aperture Solutions reportable segment offers a broad line of windows and doors at multiple price tiers for the residential new construction and repair and remodel end-markets in the U.S. and Canada. Our products mainly include vinyl, aluminum and aluminum clad-wood windows and patio doors, as well as steel, wood and fiberglass entry doors. Our product categories and collection of key brands in the Aperture Solutions reportable segment includes the following:

 Product Categories
 Brands

 Windows
 Ply Gem, Simonton, Atrium, American Craftsman, Silver Line, Cascade Windows, Prime Windows, Great Lakes Windows, North Star, Bertha, Harvey, SoftLite and Thermo-Tech.

 Doors
 Ply Gem, Simonton, Atrium, American Craftsman, Silver Line, North Star, Bertha, Harvey, SoftLite and Thermo-Tech

 We sell our windows and doors through multiple distribution channels. Our residential new construction product lines are sold across a diversified customer base, which includes independent building products dealers, regional and national lumberyards, homebuilders and contractors, and retail home centers. Our residential repair and remodel window products are primarily sold through one-step distributors, retail home centers, and independent home improvement dealers and retail home centers. Dealers typically market directly to homeowners or contractors in connection with remodeling requirements, while distributors focus primarily on selling to builders, contractors and local independent retailers. We are a key supplier to the nation's largest homebuilders, which we have served through our distribution channels and through direct relationships for over 10 years.
 In Canada, sales for residential new construction are predominantly made on a direct basis to homebuilders and contractors, while residential repair and remodel products are primarily sold through independent window dealers and regional lumberyards. We distribute Ply Gem Canada products through our distribution centers across Western Canada. In Ontario, we manufacture and distribute North Star branded windows and doors primarily for the premium-priced tier of the residential repair and remodel market.

 The North American window and patio door market remains highly fragmented. The Aperture Solutions reportable segment's main competitors include national brands such as Jeld-Wen, Pella, MI and Andersen, and regional brands such as PGT, United and Provia. Competitors in Canada include Jeld-Wen, All Weather at Home and numerous regional brands. We generally compete on aesthetics, quality, price, service, product performance, breadth of product offerings and responsiveness to distributors', retailers' and installers' needs. We believe all our products are competitively priced and that we are one of the few manufacturers to serve all end markets and price points on a national basis.
 Our Surface Solutions reportable segment offers a broad suite of surface solution products and accessories at multiple price tiers for the residential new construction and repair and remodel end markets as well as stone installation services. Our product categories and collection of key brands in the Surface Solution reportable segment include the following:

 Product Categories
 Brands

 Siding and accessories
 Ply Gem, Mastic, Mitten, Variform, MAC Metal Architectural

 Cellular PVC trim
 Ply Gem

 Vinyl fencing and railing
 Ply Gem

 Stone veneer
 Ply Gem, Environmental Stoneworks, ClipStone, Canyon Stone

 Gutter & Gutter protection
 Ply Gem, Leaf Relief, Leaf Relief Snap Tight, Leaf Smart, Leaf Logic

 We sell our Surface Solutions products mainly through wholesale and specialty distributors, retail home centers, manufactured housing producers, homebuilders, and contractors. We have an extensive network of independent dealers and distributors serving contractors and homebuilders nationwide. We believe we are well-positioned in the specialty distributor channel with many of the largest and most successful distributors in the industry. In Canada, our products are distributed nationwide, mainly through our distribution centers and to retail home centers, lumberyards and contractors.
 Our main vinyl siding competitors include CertainTeed, Alside, Westlake Royal Building Products and smaller regional competitors. Our aluminum accessories competitors include Rollex, Euramax, Gentek and other smaller regional competitors. Our vinyl fencing and railing competitors mainly include Barrette, U.S. Fence, Homeland Vinyl Products, Westech, Bufftech, and Azek. Our cellular PVC trim and moulding competitors mainly include Azek, Inteplast, KOMA, Versatex, Kleer, CertainTeed and Westlake Royal Building Products. Our stone veneer competitors mainly include Cultured Stone and Eldorado Stone, Coronado Stone Products and smaller regional competitors.
 Our Shelter Solutions reportable segment designs, engineers, manufactures and distributes an extensive line of building products for the low-rise commercial construction market under multiple brand names and through a nationwide network of manufacturing plants and distribution centers.
 We believe we maintain leading positions across all our key product categories in this reportable segment and we believe that our brands, many of which have been in use for several decades, are well-recognized by our customers and industry associations. Our principal products in this reportable segment include:
 Metal Building Systems – Metal building systems consist of engineered structural members and panels that are fabricated and roll-formed in a factory. These systems are custom designed and engineered to meet project requirements and then shipped to a construction site complete and ready for assembly with no additional field welding required. Engineered building systems manufacturers design an integrated system that meets applicable building code and designated end use requirements. These systems consist of primary structural framing, secondary structural members (purlins and girts) and metal roof and wall systems or conventional wall materials manufactured by others, such as masonry and concrete tilt-up panels.
 Our metal building systems are sold predominately under the Metallic Building Company, Ceco Building Systems, Star Building Systems, Heritage Building Systems, Robertson Building Systems brands and Mueller Building Systems brands.
 Metal Roofing and Wall Systems – These products are used in new construction and in repair and retrofit applications for industrial, commercial, institutional, agricultural, rural and residential uses. Metal components are used in a wide variety of construction applications, including purlins and girts, roofing, standing seam roofing, walls, doors, trim and other parts of traditional buildings, as well as in architectural applications and engineered building systems.

 Our residential metal roofing and wall systems are sold predominantly under key brands including Union Corrugating Company, Reed's Metals and Metal Depots brands. Our commercial metal components are sold predominately under key brands including MBCI and ABC American Building Components brands.
 Our Retail Direct business is comprised of the Heritage Building Systems, Reed's Metals, Metal Depots brands and Mueller Building Systems brands. This business sells simple metal buildings including pole barns, cold formed buildings and low-complexity pre-engineered metal buildings, metal roofing and some third party produced products to retail customers through a network of branch locations.

 Our products offer a number of advantages over traditional construction alternatives, including shorter construction time, more efficient use of materials, lower construction costs, greater ease of expansion and lower maintenance costs. We sell our products for both new construction and repair and remodel applications across a broad range of markets and customer solutions, including distribution and warehouse facilities; manufacturing and industrial facilities; as well as automotive, aviation, agricultural, healthcare, educational and retail facilities, among others.
 We compete with a number of other manufacturers of metal components and engineered building systems for the building industry, which mainly include Nucor, BlueScope, McElroy, Metal Sales and Central States. Many of these competitors operate on a regional basis. We have two primary nationwide competitors in the engineered building systems market and three primary nationwide competitors in the metal components market. The metal components market is more fragmented than the engineered building systems market.

 Other Information

 Manufacturing and Distribution
 We employ a multichannel distribution strategy with 199 manufacturing and warehouse facilities across North America. Our broad distribution network enables us to serve customers across all 50 U.S. states, all 10 Canadian provinces and other select international jurisdictions. Our integrated footprint enhances our ability to serve and develop deeper customer relationships across both our residential and commercial end markets. The breadth of diversification across our business, from what we sell, to where we sell and to whom we sell, enables significant resiliency in our business model by insulating us from any negative trends or fluctuations in any single market segment, distribution channel, customer segment or product category.

 Seasonality
 Our sales volume is generally higher during our second and third quarters, which is historically the peak season for new construction and repair and remodeling in North America. Seasonal variations in our operational results may be impacted by inclement weather and other conditions. Working capital requirements have generally been greatest during the first half of our fiscal year due to the timing of the buildup of inventory to support the heavier construction season.

 Raw Materials
 We mainly use PVC resin, aluminum and glass in our residential products and steel in our commercial products. The availability, quality and costs of many of these commodities have fluctuated, and will continue to fluctuate over time. Raw materials are mainly sourced from North America, generally available from numerous sources and the number of suppliers is adequate to support production. We have typically been able to pass commodity price increases to our customers.
 Intellectual Property
 Product innovation and branding are important to the success of our business. In addition to the brand protection offered by our trademarks, patent protection helps distinguish our unique product features in the market by preventing copying and making it more difficult for competitors to benefit unfairly from our design innovation. We hold U.S. and foreign patents covering various features used in products sold within all of our reportable segments. Although each of our reportable segments relies on a number of trademarks, patents and patent groups that, in the aggregate, provide important protections to the Company, no single trademark, patent or patent group is material to any of the Company's reportable segments. We vigorously protect our intellectual property rights.

 Human Capital Resources
 At December 31, 2024, we employed more than 18,800 full-time and part-time employees (excluding contract workers), with 81% of our workforce composed of hourly production, manufacturing, shipping, customer service and other employees. Approximately 1,900 of employees work under collective bargaining agreements. Our current agreements expire in 2025 and 2027.
 Corporate stewardship is a responsibility that is deeply embedded in our long brand history. We believe our employees drive our business and our ability to effectively serve our customers and sustain our competitive position. We endeavor to create an environment that keeps our employees safe, treats them with dignity and respect and fosters a culture of high performance. We do this through the programs summarized below, the objective and related risk of each is overseen by our Board of Directors or its committees.
 Leadership, Talent Acquisition and Talent Management
 Our team members are critical to our mission and success, and, as such, our goal is to be an employer of choice in the communities in which we operate. Essential to this is creating a workplace that promotes our core values and shared mindsets and behaviors. These elements include our commitment to customer centricity, interconnectedness, and continuous improvement. We take great care in hiring, developing and retaining our team members to maximize their individual potential and our cumulative success.
 To succeed in an ever-changing and competitive labor market, we have identified priorities we believe are critical to our success in attracting, motivating, developing, and retaining employees. These include among other things: (i) promoting health and safety (ii) providing market-competitive compensation and benefit programs, (iii) emphasizing performance management and career development, and (iv) championing an inclusive work environment. Further information is available in our Environmental, Social & Governance Report report available on our website.
 Compensation and Benefit Programs
 We are committed to providing our employees with a market-competitive compensation package that rewards performance and achievement of desired business results. Our compensation package consists of three primary benefits: pay (base pay and incentive programs), health and welfare benefits, and retirement contributions. Our programs target the market median for competitiveness. We provide benefit programs with the goal of improving physical, mental, and financial wellness of our employees throughout their employment. Some examples of this include base and variable pay, medical, dental, vision, life and accidental death and dismemberment insurance, paid time off and retirement savings plans. We analyze our compensation and benefit programs annually to ensure we remain competitive and make changes as necessary.
 Performance Management and Career Development
 Our leaders receive training on our three pillars of performance management, including goal-setting, professional development, and giving performance and development feedback. This creates the foundation for our leaders to support their teams to connect their work to our purpose, mission, values, and strategies of the Company, motivating and giving them a higher sense of purpose.
 Our talent strategy is focused on having the right people with the right skills in the right roles supporting a consistent and compelling employee experience. We believe this enables us to exceed our customers' expectations and allow our people to develop and increase their career opportunities. Our talent management process:
 • Clearly defines roles and goals;
 • Establishes clear-cut performance and behavior expectations;
 • Focuses work in alignment with business strategy and company goals; and
 • Creates consistent, structured processes to enable development and career growth, including extensive curriculum and training programs.
 We manage and measure our employee engagement with a view to gaining insight into our employees' experiences, levels of workplace satisfaction, and feelings of engagement within the Company. We measure employee engagement and manager effectiveness at least annually through our global engagement survey and strive to increase our engagement scores year-over-year. To assist in this effort, managers are given direct access to their engagement results, share these results with their teams, and create measurable action plans. The senior leadership team demonstrates their commitment to engagement through transparent communications in town halls and leadership team meetings. Engagement is also managed at the local level.

 Employee Safety and Wellness
 Cornerstone Building Brands is committed to safety as our highest priority. Safety is one of the Company's core values. We are committed to (i) providing training for our employees to perform their job tasks safely, (ii) developing and maintaining safety programs and initiatives with the purpose of eliminating all injuries, safety incidents and job-related illnesses and (iii) addressing all safety risks in a thorough and timely manner. We publicly disclose operational health and safety statistics on our rate of recordable injuries and our rate of lost workdays due to injuries involving full-time and part-time employees, temporary employees and contractors.
 Our employee safety and wellness programs are designed around enterprise-wide policies and standards and a commitment to complying with applicable laws within our manufacturing, service and install, and headquarter operations. We proactively implement management systems and procedures consistent with industry best practices to prevent employee health and safety risks and to create a strong safety culture and improve performance. We are committed to continuous improvement and continue to measure, refine, and improve on our performance. We educate and train our employees to help ensure compliance with our policies, standards, and management systems. We also have policies and procedures in place to encourage employees to stop work to address at-risk conditions without threat of retaliation. Our management and Board of Directors regularly review our health and safety results and progress at Board of Directors meetings to promote continuous improvement.

 Environmental Matters
 Sustainability
 We are well-positioned to make positive impacts on the communities we serve as we continue our journey to become North America's premier manufacturer of exterior building solutions.
 We recognize our responsibility as a provider of building solutions to communities across North America to incorporate sustainability into our products and our business operations. Our business is committed to integrating sustainability in decision making.
 In 2024, we continued our sustainability journey by establishing baselines for key sustainability metrics, implementing a SaaS application to operationalize our sustainability data and engaging our supply chain with respect to sustainability specific initiatives. We also continued to focus on a climate-positive future through energy and water conservation, landfill diversion and responsible sourcing while acting as stewards of the environment. By addressing energy usage and operational environmental impacts, we seek to have a positive impact for both our stakeholders and the planet. We are committed to the well-being of our employees, our fence line communities and the customers we serve. We believe that our sustainable business practices provide positive societal benefits for our people and our communities.
 As we continue to develop an integrated strategy of financial growth and corporate responsibility for the future, we acknowledge that there is still much work to do as we take the next steps on our sustainability journey. Our highest priority is always the safety of our employees. We are committed to conducting business at the highest levels of ethics every day.

 Environment, Health and Safety Matters
 Our operations are subject to various federal, state, local and foreign environmental, health and safety laws. Among other things, these laws regulate the emissions or discharge of materials into the environment; govern the use, storage, treatment, disposal and management of hazardous substances and wastes; protect the health and safety of our employees and the end-users of our products; regulate the chemicals imported and used in our raw materials and products; and impose liability for the costs of investigating and remediating (as well as other damages resulting from) present and past releases of hazardous substances. Violations of these laws or of any conditions contained in environmental permits could result in substantial fines or penalties, injunctive relief, consent orders, requirements to install pollution controls or other abatement equipment, or civil sanctions.
 We could be held liable for costs to investigate, remediate, or otherwise address contamination at any real property we have ever owned, operated or used as a disposal site, or at other sites where we or predecessors may have released hazardous materials. We could incur fines, penalties or sanctions or be subject to third-party claims, including indemnification claims, for property damage, personal injury or otherwise as a result of violations of (or liabilities under) environmental, health and safety laws, or in connection with releases of hazardous or other materials.
 Changes in or new interpretations of existing laws, regulations or enforcement policies, the discovery of previously unknown contamination or other environmental liabilities or obligations with respect to our products or business activities, or the

 imposition of new regulatory requirements for our facilities may lead to additional costs that could have an adverse effect on our business, financial condition or results of operations.
 We do not believe that compliance with environmental, health and safety laws, including existing requirements to investigate and remediate contamination, will have a material adverse effect on our business, financial position, or manufacturing processes.
 The following are representative environmental, health and safety requirements relating to our operations:
 Air Emissions. Our operations are subject to the federal Clean Air Act and comparable state and foreign laws. These laws govern emissions of air pollutants from industrial stationary sources, such as our manufacturing facilities, and impose various permitting, air pollution control, emissions monitoring, recordkeeping and reporting requirements. Such laws may require us to obtain pre-approval for constructing or modifying our facilities in ways that have the potential to produce new or increased air emissions; obtain and comply with operating permits that limit air emissions or certain operating parameters, or employ best available control technologies to reduce or minimize emissions from our facilities. We may be required to purchase air pollution control equipment to comply with air emissions laws.
 Greenhouse Gases. Efforts to mitigate the effects of global climate change has led to federal, state and foreign legislative and regulatory efforts to limit greenhouse gas ("GHG") emissions. While GHG regulations generally do not affect our facilities as they are insignificant sources, more stringent federal, regional, state, and foreign laws and regulations relating to global climate change and GHG emissions may be adopted similar to those established in California in 2023. These laws and regulations could impact our facilities, raw material suppliers, the transportation and distribution of our products, and our customers' businesses, which could reduce demand for our products or cause us to incur additional capital, operating or other costs. Until the timing, scope and extent of any additional future legislation or regulation becomes known, we cannot predict its effect on our business. In addition, global climate change may increase the frequency or intensity of extreme weather events, such as storms, floods, extreme temperatures and other events that could affect our facilities, our supply chain, raw material suppliers, the transportation and distribution of our products, and demand for our products.
 Hazardous and Solid Industrial Waste. Our operations generate industrial solid wastes, including some hazardous wastes that are subject to the federal Resource Conservation and Recovery Act ("RCRA") and comparable state and foreign laws. RCRA imposes requirements for the handling, storage, treatment, and disposal of hazardous waste. Industrial wastes that we generate in our manufacturing processes, such as used chemicals, may be regulated as hazardous waste, although RCRA has provisions to exempt some of our wastes from this category. However, our non-hazardous and exempted industrial wastes are still regulated under state law or the less stringent industrial solid waste requirements of RCRA.
 RCRA Corrective Action Program. Certain facilities may be subject to the Corrective Action Program under the Solid Waste Disposal Act, as amended by RCRA, and the Hazardous and Solid Waste Amendments ("Corrective Action Program"). The Corrective Action Program is designed to ensure that certain facilities subject to RCRA have investigated and remediated releases of hazardous substances at their property.
 CERCLA. The Comprehensive Environmental Response, Compensation and Liability Act ("CERCLA", commonly known as Superfund), and comparable state and foreign laws impose liability, without regard to fault or the legality of the original conduct, on certain classes of persons responsible for releases of hazardous substances into the environment. These include the current and past owners or operators of sites where hazardous substances were released, and companies that disposed or arranged for disposal of hazardous substances at off-site locations such as landfills. CERCLA authorizes the EPA and, in certain cases, third parties to take actions in response to threats to the public health and welfare or the environment and to seek to recover remediation costs from the responsible parties.
 We currently own or lease, and historically owned or leased, numerous properties that have extensive histories of industrial operations. Hazardous substances may have been released on, under or from these properties, or on, under or from other locations where hazardous wastes have been disposed. Some of these properties have been owned or operated by third parties who may have released hazardous substances for which we could have liability. We could be required to investigate or remediate contaminated property, perform remedial closure activities, or assess and remediate volatile chemical vapors migrating from soil or groundwater into overlying buildings. Our liability for investigating and remediating contamination could be joint and several and could include damages for impacts to natural resources.
 Wastewater Discharges. Our operations are subject to the federal Water Pollution Control Act, also known as the Clean Water Act ("CWA") and comparable state and foreign laws. These laws impose requirements and strict controls regarding the discharge of pollutants from industrial activity into waters of the U.S. Such laws may require that we comply with stormwater runoff and wastewater discharge standards or obtain permits limiting our discharges of pollutants. Failure to comply with

 CWA requirements could subject us to monetary penalties, injunctions, restrictions on operations, and administrative or civil enforcement actions. We may be required to incur certain capital expenditures for wastewater discharge or stormwater runoff treatment technology to comply with wastewater permits and water quality standards.
 Employee Health and Safety. We are subject to the Occupational Safety and Health Act ("OSHA") and comparable state and foreign laws that regulate the protection of the health and safety of our workers. Among other things, we are required to maintain and make available to our employees, state and local government authorities, and others information about hazardous materials used or produced by our operations.

 Item 1A. Risk Factors.
 Risks Related to Our Industry and Economic and Market Conditions
 Our industry is highly sensitive to macroeconomic conditions. Negative economic events including, but not limited to, actual or perceived economic downturns, lower business and consumer confidence, high interest rates, inflation, and lower new construction starts and repair and remodeling activity may materially and adversely affect the outlook for our business, financial condition and results of operations.

 The construction industry is highly sensitive to global, national and regional macroeconomic conditions. The risks associated with our business may become more acute in periods of a slowing economy or economic downturns, which may reduce business and consumer confidence and result in decreased demand for our products. Furthermore, rising, or volatile continued high interest rates in response to concerns about inflation may further increase economic uncertainty and heighten these risks. In addition, instability and weakness of the U.S. and global economies, including due to disruptions to financial markets, inflation, actual or perceived economic downturns, rising unemployment, geopolitical events and the negative effects on consumer spending, may materially adversely affect our business, financial condition and results of operations.

 Our residential business depends heavily on the new home construction and repair and remodel markets. Our commercial business depends heavily on the levels of commercial construction activity. Current market estimates continue to forecast high levels of volatility in 2025, including greater and faster-than-normal changes in factors such as interest rates, inflation, business and consumer confidence, unemployment, and the availability of business and consumer credit. Such volatility could cause declines in the residential and commercial construction activity markets and could lead to decreased demand for and sales of our products, which would have an adverse impact on our business, financial condition and results of operations.

 Our financial results are also impacted by our consumers' ability to finance home repair and remodeling projects or the purchase of new homes. The ability of consumers to finance these purchases is affected by such factors as new and existing home prices, homeowners' equity values, interest rates and home foreclosures, which in turn could result in a tightening of lending standards by financial institutions and reduce the ability of some consumers to finance repair and remodeling expenditures or home purchases. Declining home values, increased home foreclosures and tightening of credit standards by lending institutions have in the past and may in the future negatively impact the home repair and remodeling and the new construction sectors, which could adversely affect our business, financial condition and results of operations.

 Historically, any uncertainty about economic conditions has had a negative effect on our business, and will continue to pose a risk to our business as our customers may postpone spending in response to tighter credit, higher interest rates, negative financial news or declines in income or asset values, which could have a material negative effect on the demand for our products. Other factors that could influence demand include fuel and other energy costs, the availability or increased cost of homeowner's insurance, overall conditions in the residential and commercial real estate markets, labor and healthcare costs, access to credit, tariffs, and other macroeconomic factors.

 From time to time, our industry has also been adversely affected in various parts of the country by declines in commercial construction starts, including but not limited to, high vacancy rates, changes in tax laws affecting the real estate industry, high interest rates and the unavailability of financing. Sales of our products may be adversely affected by continued weakness in demand for our products within particular customer groups, or a continued decline in the general construction industry or

 particular geographic regions. These and other economic factors could have a material adverse effect on demand for our products and on our business, financial condition and results of operations.

 Risks Related to Our Business

 Inability to optimize operational efficiency could adversely affect our business, results of operation and financial condition.

 Our ability to sell quality products at profitable margins depends in large part on our ability to efficiently operate our facilities. We are implementing initiatives to optimize our operational efficiencies and reduce costs while ensuring superior quality. If we are unsuccessful in implementing these initiatives, or are otherwise unable to operate our manufacturing facilities efficiently, produce high quality products and provide value to our customers, our business, financial condition and results of operations could be materially and adversely affected.

 Failure to attract and retain employees could adversely affect our business, results of operation and financial condition.

 Our ability to attract and retain or replace employees is challenging due to a shortage of hourly and technically skilled workers for our manufacturing facilities and a competitive market for non-manufacturing workers. We face intense competition for talent to operate our manufacturing facilities, including from current and potential competitors in our industry. As a large-scale manufacturer, our workforce is distributed across North America, and we may incur significant costs to attract and retain employees, particularly in smaller, local markets. We also face intense competition for non-manufacturing talent given the broader labor market conditions. If we do not attract and retain the services of individuals to operate our manufacturing facilities, we may experience delays in producing our products, which may result in a reduction in net sales and an adverse effect on our business, results of operations and financial condition. In addition, if we are not successful in attracting and retaining the services of non-manufacturing workers, our business, our financial condition and results of operations could be adversely impacted.

 Increases in labor costs, potential labor disputes, union organizing activity and work stoppages at our facilities or the facilities of our suppliers and changes in demographics or regulatory conditions could delay or impede our production, reduce sales of our products and increase our costs.

 Our ability to attract and retain qualified manufacturing team members to operate our manufacturing plants efficiently is critical to our financial performance. Our financial performance is affected by the availability of qualified personnel and the cost of labor. As of December 31, 2024, about 10% of our employees were represented by labor unions, the collective bargaining agreements with whom will expire in fiscal year 2025 and 2027. We are subject to the risk that strikes or other types of conflicts with personnel may arise or that we may become a subject of union organizing activity. Furthermore, some of our direct and indirect suppliers have unionized work forces. Strikes, work stoppages or slowdowns experienced by these suppliers could result in slowdowns or closures of facilities where components of our products are manufactured. Any interruption in the production or delivery of our products could reduce sales of our products and increase our costs. Any labor shortage will create operating inefficiencies that could adversely impact our financial performance. In addition, changes in demographic or regulatory conditions in certain geographic markets, including changes in immigration law, may adversely affect our ability or our customers' ability to maintain an adequately skilled labor force.

 The industries in which we operate are highly competitive.

 Competition in the construction markets of the building industry is intense. Competition is based primarily on aesthetics, quality, price, service, product performance, breadth of product offerings and responsiveness to distributor, retailer and installer needs, as well as end-user customer preference. In addition, we also compete with alternative building products materials and alternative methods of building construction that do not utilize our products which may be viewed as more traditional, more aesthetically pleasing or having other advantages.

 In our Aperture Solutions and Surface Solutions reportable segments, we compete with other national and regional manufacturers of exterior building products. Some of these companies are larger and have greater financial resources than we do. Accordingly, these competitors may be better equipped to withstand changes in conditions in the industries in which we operate and may have significantly greater operating and financial flexibility than we do. Additionally, our products face competition from alternative materials, such as wood; composites and fiberglass in windows; metal; fiber cement; and masonry and composites in siding. In our Shelter Solutions reportable segment, we compete with a number of other manufacturers of metal components and engineered building systems ranging from small local firms to large national firms.

 In addition, we and other manufacturers of metal components and engineered building systems compete with alternative methods of building construction.

 Further, vertical consolidation by our competitors may negatively impact our ability to compete. For example, in the past several of our competitors in the Shelter Solutions reportable segment were acquired by steel producers. Competitors owned by steel producers may have a competitive advantage on raw materials that we do not enjoy. Steel producers may prioritize deliveries of raw materials to such competitors or provide them with more favorable pricing, both of which could enable them to offer products to customers at lower prices or accelerated delivery schedules.

 In all our reportable segments, failure to provide our customers with quality, service, on-time delivery and project completion, and other value additions would negatively affect our ability to compete in our industry. The resulting increased competition from other exterior building products manufacturers, as well as the competition from alternative building materials and alternative construction methods, could cause us to lose our customers and lead to net sales decreases, which would impact our results of operations.

 Price volatility and supply constraints for raw materials could prevent us from meeting delivery schedules to our customers or reduce our profit margins.

 Our business is heavily dependent on the price and supply of raw materials including steel, PVC resin, aluminum and glass. Raw material prices have been volatile in recent years and may remain volatile in the future. Raw material prices are influenced by numerous factors beyond our control, including general domestic and international economic conditions; currency fluctuations; supply constraints; competition; labor costs; freight and transportation costs; production costs; and tariffs, import duties and other trade restrictions. For example, in 2018, the Trump administration implemented new tariffs on imports of steel and aluminum into the U.S. In response to these tariffs, the European Union, Canada, Mexico and China announced tariffs on U.S. goods and services. Although some of these tariffs have been rescinded, suspended, or modified, some remain. In addition, the second Trump administration has proposed new, broad tariffs on all imports, as well as targeted tariffs on certain trading partners. We cannot predict what, if any, new tariffs will be implemented, and we are closely monitoring the administration's actions in this space, particularly for any that may affect our operations in Mexico and Canada. The current tariffs, along with any future tariffs and trade restrictions that may be implemented by the second Trump administration, could result in reduced overall economic activity and increased costs in operating our business.

 A sudden increase in demand for steel, PVC resin, aluminum or glass could affect our ability to purchase such raw materials and result in rapidly increasing prices. We have historically been able to substantially pass on significant cost increases in raw materials through price increases to our customers; however, we may not be able to do so in the future. Further, if the available supply of any of the raw materials we use declines, we could experience a deterioration of service from our suppliers or interruptions or delays that may cause us not to meet delivery schedules to our customers. Any of these problems could adversely affect our business, results of operations and financial condition. We can give no assurance that steel, PVC resin, aluminum or glass will remain available, that prices will not continue to be volatile or that we will be able to purchase these raw materials on favorable or commercially reasonable terms.

 Further, we use energy in the manufacturing and transportation of our products. In particular, our manufacturing plants use considerable amounts of electricity and natural gas. Consequently, our operating costs typically increase if energy costs rise. During periods of higher energy costs, we may not be able to recover our operating cost increases through price increases without reducing demand for our products. To the extent we are not able to recover these cost increases through price increases or otherwise, our profitability will be adversely impacted. From time to time, we may partially hedge our exposure to higher prices through fixed forward positions. However, such fixed forward positions or other hedging instruments may not fully mitigate our risk from operating cost increases.

 We rely on third-party suppliers for materials in addition to steel, PVC resin, aluminum and glass, and if we fail to identify and develop relationships with a sufficient number of qualified suppliers, or if there is a significant interruption in our supply chains, our business and results of operations could be adversely affected.

 In addition to steel, PVC resin, aluminum and glass, our operations require other raw materials from third-party suppliers. We generally have multiple sources of supply for our raw materials; however, in some cases, materials are provided by a single supplier. The loss of, or substantial decrease in the availability of, products from our suppliers, or the loss of a key supplier, could adversely impact our business, financial condition and results of operations. In addition, supply interruptions could arise from shortages of raw materials, commodity cost volatility, pandemics, labor disputes or weather conditions affecting products or shipments or other factors beyond our control. For example, U.S. and global markets are experiencing volatility

 and disruption related to the escalation of geopolitical tensions and the military conflict currently ongoing in Ukraine and the Middle East. While we do not have any customer or direct supplier relationships with any entities in Russia, Ukraine, or the Middle East, these conflicts could lead to market or operational disruptions, including significant volatility in commodity prices, credit and capital markets, as well as supply chain interruptions. Short- and long-term disruptions in our supply chain would result in a need to maintain higher inventory levels as we replace similar product, a higher cost of product and ultimately a decrease in our net sales and profitability. To the extent our suppliers experience disruptions, there is a risk for delivery delays, production delays, production issues or delivery of non-conforming products by our suppliers. Even where these risks do not materialize, we may incur costs as we prepare contingency plans to address such risks. In addition, disruptions in transportation lines could delay our receipt of raw materials. If our supply of raw materials is disrupted or our delivery times are extended, our business, results of operations and financial condition could be materially adversely affected.

 An inability to successfully develop new products or improve existing products could negatively impact our ability to attract new customers or retain existing customers, including our significant customers.

 Our success depends on meeting consumer needs and anticipating changes in consumer preferences with successful new products and product improvements. We aim to introduce products and new or improved production processes proactively to meet customer needs, and to offset obsolescence and decreases in sales of existing products. While we devote significant focus to the development of new products, we may not be successful in product development and our new products may not be commercially successful. In addition, it is possible that competitors may improve their products more rapidly or respond to changing consumer preferences more effectively, which could adversely affect our net sales. Furthermore, market demand may decline as a result of consumer preferences trending away from our categories or trending down within our brands or product categories, which could adversely impact our business, results of operations and financial condition.

 Our Aperture Solutions and Surface Solutions reportable segments depend on a core group of significant customers for a substantial portion of net sales and we expect this to continue for the foreseeable future. For the year ended December 31, 2024, the top 10 customers accounted for 59% of net sales in Aperture Solutions and 49% of net sales in Surface Solutions. The loss of, or a significant adverse change in our relationships with our largest customers, or loss of market position of any major customer, whether because of an inability to successfully develop new products or improve existing products, or otherwise, could cause a material decrease in net sales. The loss of, or a reduction in orders, from any significant customers, losses arising from customers' disputes regarding shipments, fees, merchandise condition or performance or related matters, or an inability to collect accounts receivable from any major customer could adversely impact our net sales and profitability. In addition, net sales from customers that have accounted for significant net sales in past periods, individually or as a group, may not continue, or if continued, may not reach or exceed historical levels in any period.

 Our business may be adversely affected by weather conditions and other external factors beyond our control.

 Markets for our products are seasonal and can be affected by inclement weather conditions. Historically, our business has experienced increased sales in the second and third quarters of the year due to increased construction during those periods. Because much of our overhead and operating expenses are spread ratably throughout the year, our operating profits tend to be lower in the first and fourth quarters. Inclement weather conditions can affect the timing of when our products are supplied or installed, causing reduced profit margins when such conditions exist. For example, unseasonably cold weather or extraordinary amounts of rainfall in the markets we serve may decrease construction activity.

 Further, other external factors beyond our control could cause disruptions at any of our facilities, including maintenance outages; prolonged power failures or reductions; a breakdown, failure or substandard performance of any equipment or other operational problems; disruptions in the transportation infrastructure, including railroad tracks, bridges, tunnels or roads; fires, floods, hurricanes, earthquakes or other catastrophic disasters; pandemics; or an act of terrorism. Any prolonged disruption in operations at any of our facilities could cause a significant loss in production. As a result, we could incur significantly higher costs and longer lead times associated with distributing our products to customers during the time that it takes for us to reopen or replace a damaged facility. This could cause our customers to purchase from our competitors and stop purchasing from us either temporarily or permanently, particularly where we are currently a customer's single source of supply. If any of these events were to occur, it could adversely affect our business, financial condition and results of operations.

 If we are unable to enforce our intellectual property rights, or if such intellectual property rights become obsolete, our competitive position could be adversely affected.

 As a company that manufactures and markets branded products, we rely heavily on trademark and service mark protection to protect our brands. We also have issued patents and rely on trade secret and copyright protection for certain of our technologies. These protections may not adequately safeguard our intellectual property and we may incur significant costs to defend our intellectual property rights, which may adversely affect our financial condition. There is a risk that third parties, including our current competitors, will infringe on our intellectual property rights or will claim that our products infringe on their intellectual property rights, in which case we would have to defend these rights or ourselves, which may be costly or unsuccessful.

 There can be no assurance that the efforts we have taken to protect our business with respect to intellectual property rights will be sufficient or effective. If we are unable to protect and maintain our intellectual property rights, or if there are any successful challenges to our intellectual property rights or infringement proceedings against us, our business, financial condition and results of operations could be materially and adversely affected.

 We could incur significant costs as a result of compliance with, violations of or liabilities under applicable environmental, health and safety laws.

 Our operations include 93 manufacturing facilities and 106 distribution and warehouse facilities located throughout North America (see "Item 2. Properties" for additional information). As a result, our operations are subject to various federal, state, local and foreign environmental, health and safety ("EHS") laws. Among other things, these laws (i) regulate the emissions and discharges of pollutants into the environment, (ii) govern the use, storage, treatment, disposal and management of hazardous materials and wastes, (iii) protect the health and safety of our employees, the end-users of our products, and the general public, (iv) regulate the chemicals imported and used in our raw materials and products, and (v) impose liability for the costs of investigating and remediating present and past releases of hazardous materials and other related damages. Violations of these laws or of any conditions contained in environmental permits could result in substantial fines or penalties, injunctive relief, requirements to install pollution or other controls or other equipment, civil sanctions, and in extreme cases, criminal sanctions, permit revocations, and facility shutdowns. We could be held liable for the costs to investigate, remediate or otherwise address contamination at any real property we have historically owned or, operated, at third party sites contracted for waste disposal, or at sites where predecessors released hazardous materials. We also could incur fines, penalties or sanctions or be subject to third-party claims, including indemnification claims, for property damage, personal injury or otherwise because of violations of or liabilities under EHS laws or in connection with releases of hazardous materials. In addition, changes in or new interpretations of existing EHS laws, regulations or enforcement policies, the discovery of previously unknown environmental contamination, or the imposition of other environmental liabilities or obligations in the future, in each case with respect to our operations, products or business activities, may lead to additional costs that could have a material adverse effect on our business, financial condition or results of operations. We cannot predict whether such liabilities or obligations will arise in the future or the scope thereof.

 Changes in building codes and standards could increase the cost of our products, lower the demand for our products, or otherwise adversely affect our business.

 Our products are subject to extensive and complex local, state, federal, and foreign statutes, ordinances, rules, and regulations. These mandates, including but not limited to building design safety and construction standards and zoning requirements, affect the cost, selection, and quality requirements of the products we sell, including building structures and envelopes, roofs, windows and siding. These statutes, ordinances, rules, and regulations often provide broad discretion to governmental authorities as to the types and quality specifications required for products we sell that are used in new residential and commercial construction and home renovations and improvement projects. In addition, we cannot predict whether and how any of these standards may change in the future. Ongoing compliance with current standards and with any future changes thereto may increase the costs of manufacturing our products or may reduce the demand for impacted products in affected geographical areas or product markets, which could have a material adverse effect on our business, financial condition, and results of operations.

 We face risks related to acquisitions and dispositions that could adversely affect our results of operations.

 We have a history of expansion through acquisitions, and, from time to time, we evaluate acquisitions and dispositions of assets and businesses. We believe that if our industry continues to consolidate, our future success may depend, in part, on our ability to successfully complete acquisitions. Acquisitions and dispositions involve a number of risks, including:

 • The risk of incorrect assumptions or estimates regarding the future results of an acquired business or expected cost reductions or other synergies expected to be realized as a result of acquiring the business;
 • The risk of disposing of an asset or business at a price or on terms that are less favorable than we had anticipated;
 • Difficulty in finding sellers or buyers;
 • Diversion of management's attention from existing operations;
 • Unexpected losses of key employees, customers and suppliers of an acquired business;
 • Integrating the financial, technological and management standards, processes, procedures and controls of an acquired business with those of our existing operations;
 • Increasing the scope, geographic diversity and complexity of our operations; and
 • Potential litigation or other claims arising from an acquisition or disposition.

 We can provide no assurance that we will be successful in identifying or completing any future acquisitions or dispositions or that any businesses or assets that we are able to acquire will be successfully integrated into our existing business. The incurrence of additional debt, contingent liabilities and expenses in connection with any future acquisitions could have a material adverse effect on our business, financial condition and results of operations.

 In addition, we may be subject to claims arising from the operations of businesses from periods prior to the dates we acquired them. These claims or liabilities could be significant. Our ability to seek indemnification from the former owners for these claims or liabilities is limited by various factors, including the specific limitations contained in the respective acquisition agreements and the financial ability of the former owners to satisfy such claims or liabilities. If we are unable to enforce any indemnification rights we may have against the former owners or if the former owners are unable to satisfy their obligations for any reason, including because of their current financial position, or if we do not have any right to indemnification, we could be held liable for the costs or obligations associated with such claims or liabilities, which could adversely affect our operating performance.

 We risk liabilities and losses due to personal injury, property damage or product liability claims, which may not be covered by insurance.

 Our workers are subject to hazards associated with work in manufacturing environments. Operating hazards can cause personal injury and loss of life, as well as damage to or destruction of property. We are subject to either deductible or self-insured retention amounts, per claim or occurrence, under our Property/Casualty insurance programs, as well as an individual stop-loss limit per claim under our group medical insurance plan that we believe are consistent with industry practice. The transfer of risk through insurance cannot guarantee that coverage will be available for every loss or liability that we may incur in our operations.

 Exposures that could create insured (or uninsured) liabilities are difficult to assess and quantify due to unknown factors, including but not limited to injury frequency and severity, natural disasters, terrorism threats, third-party liability, and claims that are incurred but not reported. Although we engage third-party actuarial professionals to assist us in determining our probable future loss exposure, it is possible that claims or costs could exceed our estimates or our insurance limits, or could be uninsurable. In such instances we might be required to use working capital to satisfy these losses rather than to maintain or expand our operations, which could materially and adversely affect our business, financial condition and results of operations.

 Further, we face the risk of product liability exposure, including regulatory penalties and class action and warranty claims, in the event that the use of any of our products results in personal injury or property damage. In the event that any of our products prove to be defective, among other things, we may be responsible for damages related to any defective products and may be required to cease production, recall or redesign such products. Because of the long useful life of our products, it is possible that latent defects might not appear for several years. Any insurance we maintain may not continue to be available on acceptable terms or such coverage may not be adequate for liabilities actually incurred. Further, any claim or product discontinuance, recall or redesign could result in adverse publicity against us, which could cause sales to decline, or increase warranty costs.

 Breaches of our information system security measures could disrupt our internal operations.

 We are dependent upon information technology for the distribution of information internally and also to our customers and suppliers. This information technology is subject to theft, damage or interruption from a variety of sources, including but not limited to malicious computer viruses, security breaches and defects in design. Purchase of our products may involve the

 transmission or storage of data, including in certain instances customers' business and personally identifiable information. We also hold the sensitive personal data of our current and former employees, as well as proprietary information of our business, including strategic plans and intellectual property. Thus, maintaining the security of computers, computer networks and data storage resources is a critical issue for us and our customers and employees, as security breaches could result in vulnerabilities and loss of and/or unauthorized access to confidential information.

 We have in the past experienced, and may in the future face, hackers, cybercriminals or others gaining unauthorized access to, or otherwise misusing, our systems to misappropriate our proprietary information and technology, interrupt our business, or gain unauthorized access to confidential information. For example, in August 2020, we detected a ransomware attack impacting certain of our operational and information technology systems. Promptly upon our detection of the attack, we launched an investigation, notified law enforcement and engaged the services of specialized legal counsel and other incident response professionals. While we were able to recover our critical operational data and business systems, there is no guarantee that we will have similar success with an attack in the future should one occur. Any such future attack could lead to the public disclosure of customer or employee data, our trade secrets or other intellectual property, or material financial and other information related to our business. The release of any of this information could have a material adverse effect on our business, reputation, and financial condition.

 The reliability and security of our information technology infrastructure and software, and our ability to expand and continually update technologies in response to our changing needs is critical to our business. To the extent that any disruptions or security breaches result in a loss or damage to our data, it could cause harm to our reputation or brand. This could: (i) lead some customers to stop purchasing our products and reduce or delay future purchases of our products or lead to the use of competing products; (ii) lead to private causes of action that could result in a judgment, settlement or other liability; (iii) lead to state or federal enforcement actions, which could result in fines, penalties or other liabilities and which may cause us to incur legal fees and costs; or (iv) result in additional costs associated with responding to a cyberattack. Increased regulation regarding cybersecurity may increase our costs of compliance, including fines and penalties, as well as costs of cybersecurity audits and insurance. Any of these actions could materially adversely impact our business, financial condition and results of operations.

 We have invested in protections and monitoring practices of our data and information technology to reduce these risks and continue to monitor our systems on an ongoing basis for any current or potential threats. There can be no assurance, however, that our efforts will prevent breakdowns or breaches to our or our third party providers' databases or systems that could adversely affect our business and financial condition.

 Damage to our computer infrastructure and software systems and issues relating to the incorporation of artificial intelligence ("AI") solutions into our systems, could harm our business.

 The unavailability of any of our primary information management systems for any significant period of time could have an adverse effect on our operations. In particular, our ability to deliver products to our customers when needed, collect our receivables and manage inventory levels successfully largely depend on the efficient operation of our computer hardware and software systems. Through information management systems, we provide inventory availability to our sales and operating personnel, improve customer service through better order and product reference data, and monitor results of operations. Difficulties associated with upgrades, installations of major software or hardware, and integration with new systems could lead to business interruptions that could harm our reputation, increase our operating costs, and decrease our profitability. In addition, these systems are vulnerable to, among other things, damage or interruption from power loss, computer system and network failures, loss of telecommunications services, operator negligence, physical and electronic loss of data, or security breaches and computer viruses.

 We have contracted with third-party service providers that provide us with redundant data center services in the event that our major information management systems are damaged, but they may prove to be inadequate. Our inability to restore data completely and accurately could lead to inaccurate and/or untimely financial reporting, tax filings with the Internal Revenue Service ("IRS") or other required filings, all of which could have a significant negative impact on our business, and result in fines or penalties.

 In addition, we may incorporate traditional and generative AI solutions into our information systems, products, offerings, services and features, and these solutions may become important in our operations over time. The ever-increasing use and evolution of technology, including cloud-based computing and AI, creates opportunities for the potential loss or misuse of personal data that forms part of any data set and was collected, used, stored, or transferred to run our business, and unintentional dissemination or intentional destruction of confidential information stored in our or our third party providers'

 systems, portable media or storage devices, which may result in significantly increased business and security costs, a damaged reputation, administrative penalties, or costs related to defending legal claims. If the content, analyses, or recommendations that AI programs assist in producing are or are alleged to be deficient, inaccurate, or biased, our business, financial condition, and results of operations and our reputation may be adversely affected. AI programs may be costly and require significant expertise to develop, may be difficult to set up and manage, and require periodic upgrades. There is also a risk that we may not have access to the technology and qualified AI personnel resources to adequately incorporate ongoing advancements into our AI initiatives, including access to the licensing of key intellectual property from third parties. Our competitors or other third parties may incorporate AI into their products more quickly or more successfully than us, which could impair our ability to compete effectively and adversely affect our results of operations. Our competition may have access to greater financial and technological resources, giving them a competitive advantage in recruiting, motivating, and retaining sought-after AI professionals. AI also presents emerging ethical issues and if our use of AI becomes controversial, we may experience brand or reputational harm, competitive harm, or legal liability. The rapid evolution of AI, including potential government regulation of AI, will require significant resources to develop, test and maintain our platform, offerings, services, and features to help us implement AI ethically in order to minimize unintended, harmful impact.

 Our enterprise resource planning technologies will require maintenance or replacement in order to allow us to continue to operate and manage critical aspects of our business.

 We rely heavily on enterprise resource planning technologies ("ERP Systems") from third parties in order to operate and manage critical internal functions of our business, including accounting, order management, procurement, and transactional entry and approval. Certain of our ERP Systems are no longer supported by their vendor, are reaching the end of their useful life or are in need of significant updates to adequately perform the functions we require. We have limited access to support for older software versions and may be unable to repair the hardware required to run certain ERP Systems on a timely basis due to the unavailability of replacement parts. In addition, we face operational vulnerabilities due to limited access to software patches and software updates on any software that is no longer supported by their vendor. We have started implementing a multi-year plan to upgrade and rationalize the hardware and software platforms used in our ERP Systems.

 If our ERP Systems become unavailable due to extended outages or interruptions, because they are no longer available on commercially reasonable terms or if we are unable to successfully implement our upgrade and rationalization plan, our operational efficiency could be harmed and we may face increased replacement costs. We may also face extended recovery time in the event of a system failure due to lack of resources to troubleshoot and resolve such issues. Our ability to manage our operations could be interrupted and our order management processes and customer support functions could be impaired until equivalent services are identified, obtained and implemented on commercially reasonable terms, all of which could adversely affect our business, results of operations and financial condition.

 We have identified a material weakness in our internal control over financial reporting and, if our remediation of this material weakness is not effective, or if we fail to maintain an effective system of internal control over financial reporting in the future, we may not be able to accurately or timely report our results of operations.

 In the course of preparing our financial statements for the interim period ended September 28, 2024, management identified a material weakness in our internal control over financial reporting that existed due to the implementation of a new ERP System within the Shelter Solutions reportable segment. The presence of this material weakness creates a reasonable possibility that a material misstatement to the consolidated financial statements will not be prevented or detected on a timely basis. However, no such material misstatement has occurred to date.

 We are taking steps to address these control issues. The remediation steps will require that, among other items: (i) functional business experts are identified, trained, and meet established requirements, (ii) business users have sufficient understanding of the underlying functionality being tested, and (iii) additional levels of review are established throughout the development cycle.

 While we believe that these efforts will remediate the material weakness identified, the implementation of these measures is ongoing and will require validation and testing of the design and operating effectiveness over a sustained period of financial reporting cycles.

 We cannot assure you that the measures we have taken to date, and that we are continuing to implement, will be sufficient to remediate the material weakness we have identified or that we will not uncover additional material weaknesses in the future. If the steps we take do not remediate the material weakness in a timely manner, there could continue to be a reasonable possibility that these control deficiencies or others could result in a material misstatement of our consolidated financial

 statements that would not be prevented or detected on a timely basis. If such material misstatements were not prevented or detected on a timely basis, or if we fail to maintain an effective system of internal control over financial reporting in the future, we may not be able to accurately or timely report our results of operations, which could have a material adverse effect on our business, results of operations, and financial condition.

 We may be significantly affected by new or stricter regulatory standards on sustainability matters, and by global climate change.

 We expect that regulatory standards on topics such as climate change, GHG emissions, water usage, waste management, human capital, and risk oversight will continue to evolve. Implementation of new and/or stricter regulatory standards could expand the nature, scope, and complexity of what we are required to comply with, control, assess, and report. Such changes could increase the cost of our compliance and internal risk management programs, which could have a material adverse effect on our business, results of operations, and financial condition.

 For example, the State of California established climate legislation in 2023 that will require certain U.S. companies with business activities in California to provide disclosures related to their GHG emissions, climate-related financial risks and any voluntary carbon offsets or climate related claims. The new California legislation, and the adoption of similar regulations in other U.S. states and/or Canada and Mexico are likely to increase the resources we will need to allocate for compliance. In addition, any other future, more stringent federal, regional, state and foreign laws and regulations relating to global climate change and GHG emissions, if adopted, could impact our manufacturing operations, raw material suppliers, the transportation and distribution of our products, and our customers' businesses.

 Further, global climate change may increase the frequency or intensity of extreme weather-related events, such as storms, floods, hurricanes, wildfires, extreme temperatures, and other events that could affect our facilities and, workforce, supply chain, and demand for our products, which could have a material adverse effect on our business, results of operations, and financial condition.

 We face risks related to our international operations.

 In addition to the U.S., we operate our business in certain foreign jurisdictions, principally in Canada and Mexico, and make sales in certain other jurisdictions, which poses certain risks to our business, including foreign exchange rate and international legal compliance risks.

 Our operations in Canada generated 7.1% of our net sales in 2024. As such, our net sales, earnings and cash flow are exposed to risk from changes in foreign exchange rates, which can be difficult to mitigate. Depending on the direction of changes relative to the U.S. dollar, Canadian dollar values can increase or decrease the reported values of our net assets and results of operations. We hedge this foreign currency exposure by evaluating the usage of certain derivative instruments which hedge certain, but not all, underlying economic exposures.

 Our international operations require us to comply with certain U.S. and international laws, such as import/export laws and regulations, anti-boycott laws, anti-dumping laws, economic sanctions, laws and regulations, the U.S. Foreign Corrupt Practices Act and similar anti-bribery laws. Any new tariffs and trade restrictions that may be implemented by the second Trump administration could result in reduced overall economic activity and increased costs in operating our business, which could have a material adverse effect on our business, financial condition and results of operations. See Risk Factor, "Price volatility and supply constraints for raw materials could prevent us from meeting delivery schedules to our customers or reduce our profit margins." In addition, we operate in parts of the world, including Canada and Mexico, that have experienced governmental corruption to some degree and, in certain circumstances, strict compliance with anti-bribery laws has proved challenging historically. We cannot provide absolute assurance that our internal controls and procedures will always prevent reckless or criminal acts by our employees or agents, or that the operations of acquired businesses will have been conducted in accordance with our policies and applicable regulations. If we are found to be liable for violations of these laws (either due to our own acts, out of inadvertence or due to the acts or inadvertence of others), we could suffer criminal or civil penalties or other sanctions, including limitations on our ability to conduct our business, which could have a material and adverse effect on our business, financial condition and results of operations.

 Significant changes in factors and assumptions used to measure our defined benefit plan obligations, actual investment returns on pension assets and other factors could negatively impact our results of operations and cash flows.

 The recognition of costs and liabilities associated with our pension plans for financial reporting purposes is affected by assumptions made by management and used by actuaries engaged by us to calculate the benefit obligations and the expenses recognized for these plans. The inputs used in developing the required estimates are calculated using a number of assumptions, which represent management's best estimate of the future. The assumptions that have the most significant impact on reported results are the discount rate, the estimated long-term return on plan assets for the funded plans, retirement rates, and mortality rates. These assumptions are generally updated annually.

 Changes in interest rates, mortality assumptions and asset performance may affect the funded status of our pension plans. Funding requirements for our pension plans may become more significant. If our cash flows and capital resources are insufficient to fund our pension plan obligations, we could be forced to reduce or delay investments and capital expenditures, seek additional capital, or restructure or refinance our indebtedness.

 Any impairment of our goodwill, intangible or other long-lived assets could negatively impact our results of operations and financial condition.

 We evaluate assets on our Consolidated Balance Sheets, including goodwill, intangible and other long-lived assets, annually, in the case of goodwill, or whenever events or changes in circumstances indicate that their carrying value may not be recoverable. We monitor factors or indicators, such as unfavorable variances from forecasted cash flows, and external market conditions that would require an impairment test. For example, during the third quarter of 2024, we recorded goodwill impairment charges of $12.9 million, $329.1 million, and $40.8 million related to our Aperture Solutions–U.S., Siding Solutions–U.S., and Surface Solutions–U.S. Stone reporting units, respectively, as well as an intangible impairment charge of $32.7 million related to Surface Solutions–U.S. Stone. During the fourth quarter of 2024, we recorded impairment charges related to goodwill of $483.3 million to our Aperture Solutions–U.S. reporting unit and $24.2 million and $11.8 million related to property, plant and equipment and right-of-use assets, respectively, at our Surface Solutions–U.S. Stone reporting unit. We may experience unforeseen events in the future, that could adversely affect the value of our goodwill, intangible assets or other long-lived assets and trigger other interim impairment evaluations. There can be no assurance that valuation multiples will not decline, discount rates will not increase, or the earnings, book values or projected earnings and cash flows of the Company's reporting units will not decline. Future determinations of significant impairments of goodwill, intangible assets or other long-lived assets as a result of an impairment test or any accelerated amortization of our long-lived assets could have a negative impact on the Company's business, results of operations and financial condition.

 Risks Related to our Sole Stockholder
 The interests of our controlling stockholder may differ from the interests of holders of our indebtedness.

 Following the Merger (as defined herein), investment funds managed by Clayton, Dubilier and Rice, LLC ("CD&R") own all of the Company's outstanding capital stock and have the ability to appoint the members of our Board of Directors. As a result, CD&R has significant influence over our business. The interests of CD&R may differ from those of holders of our outstanding indebtedness in material respects. For example, CD&R may have an interest in pursuing acquisitions, divestitures, financings or other transactions that, in their judgment, could enhance their overall equity investment, even though such transactions might involve risks to holders of our outstanding indebtedness. CD&R is in the business of making investments in companies, and may from time to time in the future, acquire interests in businesses that directly or indirectly compete with certain portions of our business or are our suppliers or customers. The companies in which CD&R invests may also pursue acquisition opportunities that may be complementary to our business and, as a result, those acquisition opportunities may not be available to us. Additionally, CD&R may determine that the disposition of some or all of their interests in the Company would be beneficial to them at a time when such disposition could be detrimental to the holders of our outstanding indebtedness.

 Risks Related to our Indebtedness and Liquidity
 We have substantial debt and may incur substantial additional debt, which could adversely affect our financial health, reduce our profitability, limit our ability to obtain financing in the future and pursue certain business opportunities and make payments on our indebtedness.

 As of December 31, 2024, we had outstanding principal on long-term debt totaling $4.8 billion.
 The amount of our debt or other similar obligations could have important consequences for us, including, but not limited to:

 • A substantial portion of our cash flow from operations must be dedicated to the payment of principal and interest on our indebtedness, thereby reducing the funds available to us for other purposes;
 • Our ability to obtain additional financing for working capital, capital expenditures, acquisitions, debt service requirements or general corporate purposes and our ability to satisfy our obligations with respect to our outstanding indebtedness may be impaired in the future;
 • We are exposed to the risk of increased interest rates because a portion of our borrowings is at variable rates of interest;
 • We may be at a competitive disadvantage compared to our competitors with less debt or with comparable debt at more favorable interest rates and who, as a result, may be better positioned to withstand economic downturns;
 • Our ability to refinance indebtedness may be limited or the associated costs may increase;
 • Our ability to engage in acquisitions without raising additional equity or obtaining additional debt financing may be limited in the future;
 • It may be more difficult for us to satisfy our obligations to our creditors, resulting in possible defaults on and acceleration of such indebtedness;
 • We may be more vulnerable to general adverse economic and industry conditions; and
 • Our flexibility to adjust to changing market conditions and our ability to withstand competitive pressures could be limited, or we may be prevented from making capital investments that are necessary or important to our operations, growth strategy or efforts to improve operating margins of our business units.

 If we cannot service our debt, we will be forced to take actions such as reducing or delaying acquisitions and/or capital expenditures, selling assets, restructuring or refinancing our debt or seeking additional equity capital. We can give no assurance that we can do any of these things on satisfactory terms or at all.

 Further, the terms of the Cash Flow Credit Agreement, the ABL Credit Agreement, the Side Car Term Loan Credit Agreement (each as defined in Note 9 — Debt), the August 2028 Indenture (as defined below), January 2029 Indenture (as defined below) and August 2029 Indenture (as defined below) provide us and our subsidiaries with the flexibility to incur a substantial amount of additional secured or unsecured indebtedness in the future if we or our subsidiaries are in compliance with certain incurrence ratios set forth therein. Any such incurrence of additional indebtedness may increase the risks created by our current substantial indebtedness. As of December 31, 2024, we were able to borrow up to(i) $850.0 million under the ABL Facility (as defined in Note 9 — Debt), (ii) $95.0 million under the ABL FILO Facility (as defined in Note 9 — Debt) and (iii) $92.0 million under the Cash Flow Revolver (as defined in Note 9 — Debt). Borrowings under the ABL Facility, the ABL FILO Facility and the Cash Flow Revolver would be secured.

 The Cash Flow Credit Agreement, the ABL Credit Agreement, the Side Car Term Loan Credit Agreement, and the indenture governing the terms of our 8.750% Senior Secured Notes (the "August 2028 Indenture"), the indenture governing the terms of our 6.125% Senior Notes (the "January 2029 Indenture"), and the indenture governing the terms of our and 9.500% Senior Secured Notes (the ("August 2029 Indenture") contain restrictions and limitations that could significantly impact our ability and the ability of most of our subsidiaries to engage in certain business and financial transactions.

 The Cash Flow Credit Agreement, the ABL Credit Agreement, the Side Car Term Loan Credit Agreement, the August 2028 Indenture, the January 2029 Indenture and the August 2029 Indenture contain restrictive covenants that, among other things, limit our ability and the ability of our restricted subsidiaries to:

 • Incur additional indebtedness or issue certain preferred shares;
 • Pay dividends, redeem stock or make other distributions in respect of capital stock;
 • Repurchase, prepay or redeem our subordinated indebtedness;
 • Make investments;
 • Incur additional liens;

 • Transfer or sell assets;
 • Create restrictions on the ability of our restricted subsidiaries to pay dividends to us or make other intercompany transfers;
 • Make negative pledges;
 • Consolidate, merge, sell or otherwise dispose of all or substantially all of our assets;
 • Enter into certain transactions with our affiliates; and
 • Designate subsidiaries as unrestricted subsidiaries.

 In addition, the Cash Flow Revolver requires us to maintain a maximum total secured leverage ratio under certain circumstances, and the ABL Facility require us to maintain a minimum consolidated fixed charge coverage ratio under certain circumstances. The ABL Credit Agreement also contains other covenants customary for asset-based facilities of this nature. Our ability to borrow additional amounts under the Cash Flow Revolver and the ABL Facility depends upon satisfaction of these covenants. Events beyond our control can affect our ability to meet these covenants.

 We are required to make mandatory pre-payments under the Cash Flow Credit Agreement, the Side Car Term Loan Credit Agreement and the ABL Credit Agreement upon the occurrence of certain events, including the sale of assets and the issuance of debt, in each case subject to certain limitations and conditions set forth in the Cash Flow Credit Agreement, the Side Car Term Loan Agreement and the ABL Credit Agreement. In addition, under the Cash Flow Credit Agreement, the Side Car Term Loan Credit Agreement, the August 2028 Indenture, the January 2029 Indenture and the August 2029 Indenture, we are required to reinvest or repay debt in an amount equal to the proceeds of divestitures within 18 months of the closing date of such divestiture. There can be no assurance that we will have the funds necessary to comply with the requirement and that the failure to comply may have a materially adverse effect on our business, financial condition and results of operations.

 In addition, under certain circumstances and subject to the limitations set forth in the Cash Flow Credit Agreement and the Current Term Loan Facility (as defined in Item 7, "Management's Discussion and Analysis of Financial Condition and Results of Operations") may require us to make prepayments of the term loans to the extent we generate excess positive cash flow each year.

 Any future financing arrangements entered into by us may also contain similar covenants and restrictions. As a result of these covenants and restrictions, we may be limited in our ability to plan for or react to market conditions or to meet extraordinary capital needs or otherwise restricted in our activities. These covenants and restrictions could also adversely affect our ability to finance our future operations or capital needs or to engage in other business activities that would be in our interest.

 Our failure to comply with obligations under the Cash Flow Credit Agreement, the ABL Credit Agreement, the Side Car Term Loan Credit Agreement, the August 2028 Indenture, the January 2029 Indenture or the August 2029 Indenture as well as others contained in any future debt instruments from time to time, may result in an event of default under the Cash Flow Credit Agreement, the ABL Credit Agreement, the Side Car Term Loan Credit Agreement, the August 2028 Indenture, the January 2029 Indenture or the August 2029 Indenture, as applicable. A default, if not cured or waived, may permit acceleration of our indebtedness. If our indebtedness is accelerated, we cannot be certain that we will have sufficient funds available to pay the accelerated indebtedness or that we will have the ability to refinance the accelerated indebtedness on terms favorable to us or at all. If we are forced to refinance these borrowings on less favorable terms or cannot refinance these borrowings, our business, results of operations, financial condition and cash flows could be adversely affected.

 An increase in interest rates would increase the cost of servicing our debt and could reduce our profitability, decrease our liquidity and impact our solvency.

 Our indebtedness under the Cash Flow Facilities, the ABL Facilities and the Side Car Term Loan Facility, due August 2028 (each as defined in Note 9 — Debt) bears interest at variable rates, and our future indebtedness may bear interest at variable rates. As a result, increases in interest rates could increase the cost of servicing such debt and materially reduce our profitability and cash flows. While the Board of Governors of the U.S. Federal Reserve System lowered interest rates slightly multiple times in 2024 after three years of rate increases, it may raise interest rates again in the future based on U.S government policies and/or macroeconomic conditions. As of December 31, 2024, assuming all Cash Flow Revolver and ABL Facilities revolving loans were fully drawn and SOFR exceeded 0.00%, each one percent change in interest rates would result in an approximately $10.4 million change in annual interest expense on the Side Car Term Loan Facility, the Cash Flow Revolver and the ABL Facilities (excluding the impact of any Company hedging arrangements). The impact of such an increase would be more significant for us than it would be for some other companies because of our substantial debt.

 In addition, an increase in interest rates would generally lead to a decline in residential and commercial new construction starts and residential repair and remodeling activity, which could adversely affect our business, financial condition and results of operations. See Risk Factor "Our industry is highly sensitive to macroeconomic conditions. Negative economic events including, but not limited to, actual or perceived economic downturns, lower business and consumer confidence, high interest rates, inflation, and lower new construction starts and repair and remodeling activity may materially and adversely affect the outlook for our business, financial condition and results of operations."

 We may have future capital needs and may not be able to obtain additional financing on acceptable terms or at all.

 Although we believe that our current cash position and the additional committed funding available under the ABL Facilities and the Cash Flow Revolver is sufficient for our current operations, any reductions in our available borrowing capacity, or our inability to renew or replace our debt facilities, when required or when business conditions warrant, could have a material adverse effect on our business, financial condition and results of operations. Our ability to secure additional financing or financing on favorable terms and to satisfy our financial obligations under indebtedness outstanding from time to time will depend upon our future operating performance, the availability of credit generally, economic and market conditions and financial, business and other factors, many of which are beyond our control.

 If financing is not available when needed, or is available on unfavorable terms, we may be unable to take advantage of business opportunities or respond to competitive pressures, any of which could have a material adverse effect on our business, financial condition and results of operations. If we raise additional funds through further issuances of equity, convertible debt securities or other securities convertible into equity, our existing stockholders could suffer significant dilution.

 Our credit ratings are important to our cost of capital. The major debt rating agencies routinely evaluate our debt based on a number of factors, which include financial strength and business risk as well as transparency with rating agencies and timeliness of financial reporting. A downgrade in our debt rating could result in increased interest and other expenses on our existing variable interest rate debt, and could result in increased interest and other financing expenses on future borrowings. Downgrades in our debt rating could also restrict our access to capital markets and affect the value and marketability of our outstanding notes.

 Our ability to access future financing also may be dependent on regulatory restrictions applicable to banks and other institutions subject to U.S. federal banking regulations, even if the market would otherwise be willing to provide such financing.

 Item 1C. Cybersecurity
 Risk Management and Strategy

 Risk Assessments

 The Company recognizes the critical importance of developing, implementing, and maintaining robust cybersecurity measures to safeguard our information systems and protect the confidentiality, integrity, and availability of our data. The Company has integrated cybersecurity risk management into our broader enterprise risk management framework to promote a company-wide culture of cybersecurity risk awareness and management. This integration aims to ensure that cybersecurity considerations are an integral part of our decision-making processes at every level.

 We maintain an enterprise risk management program ("ERM") designed to assess, identify, manage and mitigate material risks, including cybersecurity risk. ERM is a Company-wide initiative that involves both the Board of Directors and the Company's management. The program is designed to (i) identify and assess risks most critical to the Company's success including through detailed analysis of the likelihood of occurrence and potential impact of each risk, (ii) assign individual executives the responsibility of managing those risks, and (iii) align those management assignments with appropriate board-level oversight.

 Our General Counsel and Assistant General Counsel – Compliance drive the program. The executive leadership team, including our Chief Executive Officer, and the Company's management team, comprised of department leaders and subject matter experts, are responsible for identifying, assessing managing and mitigating risks. With respect to cybersecurity risk, our legal and compliance team works closely with our IT leaders to evaluate and address cybersecurity risks in alignment with our business objectives and operational needs.

 External experts supplement our internal expertise as necessary. Risks identified as significant risks are communicated to the Board of Directors, who ultimately oversees the program both directly and indirectly through Board Committees, such as the Audit Committee.

 Risk management, including risks related to cybersecurity is also incorporated into the review and approval process for our project management organization ("PMO").

 Our cybersecurity risk management program includes enterprise-wise monitoring of cyber activity to identify and analyze potential events that may have an adverse effect or impact on the Company's assets, systems, resources or reputation. This monitoring is designed to identify both external activity and routine internal activity for behavior that may be unusual or potentially malicious. Depending upon the nature and severity of the risk, cybersecurity monitoring and identification can result in automated processes to immediately block and remove undesired risks, cybersecurity team review and action, or both. The Cybersecurity Incident Response Plan provides a framework for addressing a cyber-crisis, cyber-incident and/or data breach, which could include activating crisis, or business continuity recovery plans, as appropriate. These plans are regularly reviewed and updated by our Chief Information Officer and communicated to appropriate stakeholders.

 Third-Party Engagement

 Recognizing the complexity and evolving nature of cybersecurity threats, the Company engages with a range of external experts, including cybersecurity assessors, consultants, and auditors in evaluating and testing our risk management systems. These partnerships enable us to leverage specialized knowledge and insights, with the aim of modeling our cybersecurity strategies and processes after industry best practices. Our collaboration with these third parties includes managed services, team augmentation, independent audits, vulnerability management, threat and attack and consultation on security risks enhancements. Some engagements involve point in time activities with end products or reporting while others involve ongoing monitoring and management of risk across the Company.

 Third-Party Risk Management

 Because we are aware of the risks associated with third-party service providers, such as suppliers, software and cloud-based service providers, and cybersecurity partners, the Company implements processes to oversee and manage these risks. We assess the risks from cybersecurity threats that impact select suppliers and third-party service providers with whom we share personal identifying and confidential information. We require third parties to maintain security controls to protect our confidential information and data and notify us of breaches that may impact our data. Third parties that interact with our information or have access to our systems may have additional security requirements depending on the levels of risk. When new third-party risks are identified, we require those impacted to implement appropriate remediations or controls. Identified risks are documented and tracked along with general ongoing monitoring of third parties external risk posture. This approach is designed to mitigate risks related to data breaches or other security incidents originating from third party service providers.

 Learning from Threats/Incidents

 During the last year we have not identified cybersecurity threats or challenges that have materially impaired our operations or financial condition. Our monthly baselines for cybersecurity are closely tracked and show a continual improvement and reduction of risk over the last three years. Similarly, incident investigations over the same period have reduced in severity and frequency. These internal metrics are consistent with our third-party risk scorecard subscriptions which similarly show a year-over-year improvement in our risk posture over the last three years. See Risk Factor, "Damage to our computer infrastructure and software systems and issues relating to the incorporation of artificial intelligence ("AI") solutions into our systems, could harm our business."

 Board Oversight

 The Board of Directors has established robust oversight mechanisms designed to ensure effective governance in managing risks associated with cybersecurity threats due to the significance of these threats to our operational integrity. The Board of Directors has delegated to the Audit Committee oversight over cybersecurity risk.

 Governance – Conveying Risks to the Board of Directors

 The Chief Information Officer ("CIO") and Chief Financial Officer ("CFO") play a pivotal role in keeping the Audit Committee apprised of cybersecurity risks. They provide comprehensive briefings to the Audit Committee on a quarterly basis at the Audit Committee meetings. These briefings encompass a broad range of topics, including:

 • Current cybersecurity landscape and emerging threats
 • Status of ongoing cybersecurity initiatives and strategies
 • Incident reports and learnings from cybersecurity events; and
 • Compliance with regulatory requirements and industry standards.

 In addition to our scheduled meetings, the Audit Committee, CIO and CFO maintain an ongoing dialogue regarding emerging or potential cybersecurity risks to ensure that the Board Director's oversight is proactive and responsive. The Audit Committee actively participates in strategic decisions related to cybersecurity, offering guidance for major initiatives. Furthermore, significant cybersecurity matters, and strategic risk management decisions are escalated to the Audit Committee or Board of Directors, as appropriate, through the Board-approved escalation protocol.

 Governance and Management

 Primary responsibility for assessing, monitoring and managing our cybersecurity risks rests with our Director Cyber Security under the oversight of the Chief Information Officer. With over 20 years in the field of IT and cybersecurity, the Director, Cyber Security has significant professional experience including senior technical leadership roles along with consulting and management roles at public and private companies in the manufacturing, chemical and oil and gas sectors. His in-depth knowledge and experience are instrumental in developing and executing our cybersecurity strategies. He holds a masters in science degree from the University of Texas at Austin and professional certifications that include a CISSP and an active U.S. Government security clearance. Our Director Cyber Security oversees our cybersecurity governance programs and leads a team responsible for cybersecurity risk assessment, continuous monitoring for internal and external threats and vulnerabilities, remediation of known risks, and employee cybersecurity training.

 Management Oversight

 Our Director, Cyber Security and Chief Information Officer are regularly informed about the latest developments in cybersecurity, including potential threats and innovative risk management techniques. Keeping senior management abreast of the cybersecurity posture and potential risks facing the Company is viewed as crucial for the effective prevention, detection, mitigation, and remediation of cybersecurity incidents. The Director, Cyber Security leads a team of cybersecurity engineers, manages vendor relationships, and is responsible for implementation and oversight of processes for monitoring enterprise information systems. These processes include the deployment of advanced cybersecurity platforms which continually assess, remediate and provide regular measures and regular system audits so that identified threats and potential vulnerabilities can be addressed. In the event of a cybersecurity incident, the Director Cyber Security is equipped with our Cybersecurity Incident Response Plan. This plan includes an escalation protocol to ensure Company leaders and the Board of Directors are aware of and can oversee response plans, immediate actions to mitigate the impact and long-term strategies for remediation and prevention of future incidents. Processes also include escalating potentially material incidents directly to the General Counsel to ensure incidents are reported as required by applicable law and regulation. Both the Board of Directors and the Company's IT Steering Committee, which is comprised of senior executives are kept updated on any material incidents, cybersecurity initiatives and the Company's cybersecurity strategic roadmap.

 Item 3. Legal Proceedings.
 In July 2022, and pursuant to an Agreement and Plan of Merger dated March 5, 2022, Clayton, Dubilier and Rice, LLC ("CD&R") became the indirect owner of Cornerstone Building Brands. In January 2023, purported former stockholders filed 2 separate complaints challenging the fairness of the Merger. The complaints are captioned Firefighters' Pension System of the City of Kansas City, Missouri Trust and Gary D. Voigt v. Affeldt et al., C.A. No. 2023-0091-JTL (Del. Ch.) and Whitebark Value Partners LP and Robert Garfield v. Clayton Dubilier & Rice, LLC et al., C.A. No. 2023-0092-JTL (Del. Ch.). In both complaints, the plaintiffs allege that CD&R and its affiliates controlled the Company prior to the transaction and that certain directors and officers of the Company, as well as CD&R and its affiliates, breached their fiduciary duties and engaged in conduct resulting in a sale of the Cornerstone Building Brands public stockholders' shares to CD&R at an unfair price. The plaintiffs seek unspecified monetary damages, attorneys' fees, expenses and costs. The court consolidated the two cases, and on May 3, 2023, selected Whitebark Value Partners LP as lead plaintiff. On July 14, 2023, the defendants moved to dismiss the operative complaint. The motion to dismiss was denied on January 10, 2024, and the case is ongoing. On June 26, 2024, the plaintiffs filed an amended complaint. On February 24, 2025, the parties to the case filed a Stipulation of Compromise and Settlement ("Stipulation") setting forth their agreement to settle the litigation. The Stipulation remains subject to court approval. The Stipulation provides for CD&R and the Company, on behalf of the defendants, to pay or cause their respective insurers to pay a total of $45.0 million into an escrow account that will be used to pay escrow expenses, satisfy any fee and incentive amounts awarded by the court in favor of plaintiff and plaintiff's counsel, and distribute the remaining funds to the non-affiliated shareholders of the Company. The Company's portion of the proposed settlement relating to its indemnification of its former directors and officers is recoverable from insurance. The agreement is contingent upon final court approval, which is anticipated to occur later in 2025.

 In June 2023, a purported former stockholder filed a class action complaint in the United States District Court for the District of Delaware alleging that the Company's disclosures issued in connection with the Merger were materially misleading in violation of Section 14(a) and Section 20(a) of the Securities Exchange Act of 1934. The complaint is captioned Water Island Merger Arbitrage Institutional Commingled Master Fund, L.P. v. Cornerstone Building Brands et al., Case No. 1:23-cv-00701 (D. Del.). The complaint alleges that the Company's directors and officers issued misleading disclosures, which caused stockholders to approve the Merger at an unfair price. The plaintiff seeks unspecified monetary damages, interest, attorney's fees, expenses and costs. On December 8, 2023, the defendants moved to dismiss the operative complaint, and, in the alternative, to stay in litigation. On September 30, 2024, the court granted the defendants' motion to dismiss without prejudice. On October 15, 2024, the plaintiffs filed an amended complaint, which the defendants again moved to dismiss or stay on November 26, 2024. The Company intends to vigorously defend against these claims. The Company cannot predict with any degree of certainty the outcome of this matter or determine the extent of any potential liabilities. The Company also cannot provide an estimate of the possible loss or range of loss.

 As a manufacturer of products primarily for use in residential and commercial building construction, we are inherently exposed to a variety of litigation and other proceedings incidental to its business, including lawsuits involving claims for damages arising out of its products, employment matters, commercial disputes, product liability and personal injury as well as regulatory investigations or enforcement. We insure against these risks to the extent deemed prudent by our management and to the extent insurance is available. Many of these insurance policies contain deductibles or self-insured retentions in amounts we deem prudent and for which we are responsible for payment. In determining the amount of self-insurance, it is our policy to self-insure those losses that are predictable, measurable, and recurring in nature. The Company regularly reviews the status of on-going proceedings and other contingent matters along with legal counsel. Liabilities for such items are recorded when it is probable that the liability has been incurred and when the amount of the liability can be reasonably estimated. Liabilities are adjusted when additional information becomes available. Based on current information, experience, and applicable law management believes that the ultimate disposition of these matters will not have a material adverse effect on the Company's results of operations, financial position or cash flows. However, such matters are subject to many uncertainties and outcomes are not predictable with assurance.

 Our Business
 Cornerstone Building Brands, Inc. ("Cornerstone Building Brands" or, collectively with its subsidiaries, unless the context requires otherwise, the "Company") is a holding company incorporated in the State of Delaware. The Company is a leading exterior building products manufacturer; by sales; in North America and serves residential and commercial customers across new construction and the repair and remodel end markets.
 Our mission is to be relentlessly committed to our customers and to create superior exterior building solutions that enable communities to grow and thrive. All references herein for the year "2024" represents the year ended December 31, 2024 and "2023" represents the year ended December 31, 2023.
 The Company is organized in three reportable segments: Aperture Solutions, Surface Solutions and Shelter Solutions. There was no change in the composition of our reportable segments:
 • Through our Aperture Solutions reportable segment, we offer a broad line of windows and doors at multiple price-points for residential new construction and repair and remodel end markets in the United States ("U.S.") and Canada. Our main products include vinyl, aluminum, wood-composite and aluminum clad-wood windows and patio doors, as well as steel, wood-composite, and fiberglass entry doors.
 • Our Surface Solutions reportable segment offers a broad suite of exterior surface solutions products and accessories at multiple price-points for the residential new construction and repair and remodel end markets. Our main products include vinyl siding and accessories, cellular PVC trim, vinyl fencing and railing, stone veneer and gutter protection products, as well as stone installation services.
 • In our Shelter Solutions reportable segment, we design, engineer, manufacture and distribute an extensive lines of metal products for the low-rise commercial construction market under multiple brand names and through a nationwide network of manufacturing plants and distribution centers. We define low-rise commercial construction as building applications of up to five stories.
 Costs related to other business activities, primarily our corporate headquarters functions, are disclosed separately from the three reportable segments as "Corporate and Other." See Note 18 – Reportable Segment and Geographical Information, in our Consolidated Financial Statements located in Part II, Item 8 of this Form 10-K for additional information.

 Significant Business Developments
 Our significant business development activities in 2024 and 2023 included:
 • In August 2023, we completed the acquisition of M.A.C. M tal Architectural Inc. ("MAC Metal"), a manufacturer of high-end steel siding and roofing products.
 • In December 2023, we completed the acquisition of the Eastern Architectural Systems ("EAS") business, which manufactures custom-made aluminum and vinyl impact windows and doors.
 • In April 2024, we completed the acquisition of Harvey Building Products Corp. ("Harvey"), a manufacturer of high performing windows and doors which include the brands Harvey, Softlite and Thermo-Tech.
 • In July 2024, we completed the acquisition of Mueller Supply Company, Inc. ("Mueller"), a leading manufacturer of residential metal roofing and components in steel buildings.
 The impact of acquisitions and divestitures, when presented, is quantified as the portion of the preceding twelve months post- or pre-transaction where no comparable period is available.
 Goodwill, Intangible Asset and Property, Plant and Equipment Impairment
 Our 2024 results reflect goodwill impairment losses of $866.1 million, consisting of $382.8 million in the third quarter and $483.3 million in the fourth quarter. In the second half of 2024, we assessed the changes in circumstances that occurred during the period to determine if it was more likely than not that the fair values of any reporting units were below their carrying amounts. While there was no single determinative event or factor, the consideration in totality of several factors, including, among others: (i) the recessionary impacts on residential and commercial markets; (ii) elevated interest rates and home affordability concerns, (iii) the potential for new or modified tariffs on steel and aluminum, and (iv) the decline in home equity borrowings is anticipated to have a considerable effect on the repair and remodel market, led us to conclude the impairment tests were necessary.
 Additionally, the Company recognized an impairment loss of $68.7 million related to long-lived assets in its Surface Solutions–U.S. Stone asset group that was allocated to intangible assets of $32.7 million, property, plant and equipment of $24.2 million, and lease right-of-use assets of $11.8 million.
 See Critical Accounting Estimates within this item and Note 5, Property, Plant and Equipment, Net, Note 6, Goodwill and Intangible Assets and Note 8, Leases in Item 8, Financial Statements and Supplementary Data, to the consolidated financial statements for additional information.

 Financial Measures
 Seasonality
 Our sales volume is generally higher during our second and third quarters, which is historically the peak season for new construction and repair and remodeling in North America. Seasonal variations in our operational results may be impacted by inclement weather and other conditions. Working capital requirements have generally been greatest during the first half of our fiscal year due to the timing of the buildup of inventory to support the heavier construction season.

 Net sales for 2024 decreased $104.9 million, or 1.9%, compared to 2023, mainly due to lower volume across all reportable segments, partially offset by the strategic acquisitions of MAC Metal in August 2023, EAS in December 2023, Harvey in April 2024 and Mueller in July 2024.
 Gross profit as a percentage of net sales was 20.7% for 2024 compared to 22.3% for 2023, primarily due to higher material costs, principally at Shelters Solutions, higher labor costs, and unfavorable price over inflation, partially offset by manufacturing net efficiencies and lower depreciation and amortization expense.
 Selling, general and administrative expenses increased $60.0 million, or 6.3%, for 2024 compared to 2023, mainly due to the impact of acquisitions, partially offset by favorable non-labor spending.
 Impairment of goodwill, intangible assets and property, plant and equipment consists of impairment charges for goodwill of $866.1 million, for intangibles of $32.7 million, property plant and equipment of $24.2 million and right of use assets of $11.8 million recorded during 2024. No goodwill or intangibles impairment charges were recorded during 2023.
 Loss on divestiture consists of a gain recognized to finalize working capital in connection with the strategic divestiture of our coil coatings business of $10.1 million during 2023.
 Interest expense increased by $69.5 million, or 18.3%, for 2024 compared to 2023. The following table sets forth the components of interest expense:

 (1) The fair value adjustments were made in connection with the Merger transaction in July 2022, under which investment funds managed by Clayton, Dubilier and Rice ("CD&R") became indirect owners of all the issued and outstanding shares of Cornerstone Building Brands (the "Merger").
 Interest on outstanding borrowings increased due to higher interest on borrowings used to finance the Harvey and Mueller acquisitions during 2024.
 Foreign exchange gain (loss) for the years 2024 and 2023 are attributable to foreign exchange rate changes on intercompany loans based in Canadian currency.
 Loss on extinguishment of debt includes a loss totaling $0.2 million for 2023, which resulted from the repurchase of our 6.125% Senior Notes due January 2029 ("the 6.125% Senior Notes").
 Other income, net for 2024 decreased $9.3 million compared to 2023 primarily due to a decrease in interest income earned on money market funds. The Company exited the money market investment funds at the end of 2023.
 Income tax benefit effective tax rate was 9.3% in 2024 and 36.5% in 2023. The change was mainly due to pre-tax book losses resulting from impairment charges to deductible and non-deductible goodwill and intangible assets during 2024 and additional book amortization and depreciation related to the Merger transaction. Also, during 2023, there was an impact to the state income tax due to internal restructuring.

 Depreciation and amortization decreased by $10.9 million for 2024, mainly due to the Company recording a cumulative catch-up adjustment during the prior year as a result of the change in fair value of the underlying assets as of the date of the Merger. These changes included shortened useful lives and a higher depreciable base. The catch-up entries in 2023 are partially offset by the acquisitions of EAS and MAC Metal in 2023 and Harvey and Mueller in 2024. Intangible amortization increased principally due to higher acquisition-related amortization.

 Non-GAAP Financial Measures
 We use several measures derived from consolidated financial information, but not presented in our Consolidated Financial Statements prepared in accordance with accounting principles generally accepted in the U.S ("U.S. GAAP"). These measures are considered non-GAAP financial measures. Specifically, in this report, we refer to adjusted EBITDA, which is a non-GAAP financial measure. Our non-GAAP financial measure is not intended to replace the presentation of the comparable measure under U.S. GAAP. However, we believe the presentation of the non-GAAP financial measure, when considered together with the comparable U.S. GAAP financial measure, along with a reconciliation to its respective U.S. GAAP financial measure, assists investors in understanding the factors and trends affecting our underlying business that could not be obtained absent these disclosures. Additionally, we believe that the presentation of our non-GAAP financial measure enables investors to evaluate trends in the business excluding certain items which are not entirely a result of our base operations.
 Furthermore, the presentation of this non-GAAP financial measure supplements other metrics we use to internally evaluate our business and facilitates the comparison of past and present operations. The non-GAAP financial measure we use may differ from non-GAAP financial measures used by other companies, and other companies may not define non-GAAP financial measures we use in the same way.

 Liquidity and Capital Resources
 Our main liquidity and capital resource needs are payments to service our debt, ongoing operations and working capital requirements, capital expenditures and the cost of acquisitions. Our primary source of liquidity is cash generated from our continuing operations, as well as borrowings under our credit facilities. We believe that funds provided by these sources will be adequate to meet our liquidity and capital resource needs for at least the next 12 months under current operating conditions.
 We may from time to time take steps to reduce our debt. These actions may include repurchases or opportunistic refinancing of debt. The amount of debt, if any, that may be repurchased or refinanced will depend on market conditions, trading levels of our debt, our cash position, compliance with debt covenants and other considerations. Our affiliates may also purchase our debt from time to time, through open market purchases or other transactions. In such cases, our debt may not be retired, in which case we would continue to pay interest in accordance with the terms of such debt, and we would continue to reflect the debt as outstanding in our consolidated balance sheets.

Availability is also reduced by issuance of letters of credit.
 (2) As of December 31, 2024, we had standby letters of credit serving as a collateral for insurance carriers in the amount of $42.5 million.
 During the first quarter of 2025, the Company borrowed $170.0 million on the ABL Facility.

 Net Cash from Operating Activities
 Net cash provided by operating activities consists mainly of: (i) cash collections on credit sales to our customers, (ii) purchases of commodity based raw materials, (iii) labor and other employee-related expenditures, (iv) other non-labor costs, such as, among other items, supplies, insurance, advertising and marketing costs, (v) interest paid on our long-term debt and (vi) payments for income taxes.

 During 2024, the Company generated cash flow from operations of $15.8 million, a decrease from the $400.2 million provided by operations in the prior year. The decrease is due to lower results from operations, higher cash-based interest, higher income taxes paid and unfavorable working capital.
 Net Cash from Investing Activities
 Our main uses of cash for investing activities are for payments for property and equipment and acquisitions of businesses.
 Net cash from investing activities was $1,134.5 million during 2024 compared to $421.9 million used in investing activities during 2023. Net cash from investing activities during 2024 is mainly driven by higher capital expenditures and the acquisitions of Harvey and Mueller in 2024.
 Net Cash from Financing Activities
 Our main uses of cash for financing activities include activity to repurchase and make payments on our long-term debt and distributions to our direct parent Camelot Return Intermediate Holdings, LLC, ("Camelot Parent"). Our main sources of cash from financing activities include the proceeds from issuances of debt.
 Net cash provided by financing activities was $814.8 million during 2024 compared to $62.9 million used in financing activities during 2023. The $877.7 million increase is mainly driven by $1,335 million in additional short-term borrowings and $500.0 million in long-term borrowings through amendments to our ABL Credit Agreement and term loan facility and the issuance of the 9.500% Senior Secured Notes during 2024. The increase is partially offset by the dividend payment of $231.6 million made to Camelot Parent and $1,239.9 million in repayments of short-term borrowings.

 Contractual and Off Balance Sheet Obligations
 We have leases for certain manufacturing, warehouse, distribution locations, offices, vehicles and equipment. Our property leases generally contain renewal and escalation clauses and other concessions. These provisions are considered in our calculation of our minimum lease payments that are recognized as expense on a straight-line basis over the applicable lease term. Any lease payments that are based upon an existing index or rate are included in our minimum lease payment calculations. As of December 31, 2024, the Company had total future lease payments of $690.3 million, with $121.5 million payable within 12 months. See Note 8 — Leases in the Notes to the Consolidated Financial Statements for additional information. We have certain long-term debt instruments outstanding. As of December 31, 2024, the Company had total future payments of $4.8 billion, with $34.0 million payable within 12 months. See Note 9 — Debt in the Notes to the Consolidated Financial Statements for additional information.

 Critical Accounting Policies and Estimates
 Our significant accounting policies are described in Note 2, Significant Accounting Policies, to our Consolidated Financial Statements in Item 8 of this Annual Report on Form 10-K. The Consolidated Financial Statements are prepared in conformity with U.S GAAP. Preparation of the financial statements requires us to make judgments, estimates and assumptions that affect the amounts of assets and liabilities reflected in the financial statements and net sales and expenses reported for the relevant reporting periods. We believe the policies discussed below are the Company's critical accounting policies as they include the more significant, subjective and complex judgments and estimates made when preparing our consolidated financial statements. While our estimates are based on our knowledge of current events and actions we may undertake in the future, actual results may ultimately differ from these estimates and assumptions.
 Accounting for Business Combinations
 Accounting for the acquisition of a business requires the allocation of the purchase price to the various assets and liabilities of the acquired business. For most assets and liabilities, purchase price allocation is accomplished by recording the asset or liability at its estimated fair value. The most difficult estimations of individual fair values are those involving property, plant and equipment and identifiable intangible assets. We must also refine these estimates over a one-year measurement period, to reflect any new information obtained about facts and circumstances that existed as of the acquisition date that, if known, would have affected the measurement of the amounts recognized as of that date.
 These fair market value assessments require judgments and estimates that can be affected by various factors over time, which may cause final amounts to be materially adjusted from original estimates in subsequent periods. The significant judgments include (i) the estimation of future cash flows, which are dependent on forecasts, (ii) the estimation of a long-term rate of growth, (iii) the estimation of the useful life of the assets, and (iv) the determination of a risk-adjusted weighted average cost of capital. When appropriate, our estimates of the acquired fair values include assistance from an independent third-party.

 Inventories, long-lived assets (primarily property, plant and equipment), goodwill, and intangible assets generally represent the largest components of our acquisitions. In addition, we also acquire other categories of assets and liabilities which can include, but are not limited to, accounts receivable, accounts payable and other working capital. Due to their short-term nature, the fair values of these assets and liabilities generally approximate the carrying values reflected on the acquired balance sheet. However, when appropriate, we adjust these carrying values for factors such as collectability, existence, and consistency with Company accounting policies. We record the excess of consideration transferred over the fair value of the identifiable net assets acquired as goodwill.
 During current year, the Company acquired Harvey in April and Mueller in July. Refer to Note 3, Mergers, Acquisitions and Divestitures to our Consolidated Financial Statements for additional details.
 Impairment of Goodwill
 We have six reporting units defined as "Aperture Solutions–U.S.," "Aperture Solutions–Canada," "Surface Solutions–U.S. Siding," "Surface Solutions–Canada," "Stone Solutions" and "Shelter Solutions." Aperture Solutions–U.S. and Aperture Solutions–Canada reporting units are part of the Aperture Solutions reportable segment. Surface Solutions–U.S. Siding, Surface Solutions–Canada and Surface Solutions–U.S. Stone are part of the Surface Solutions reportable segment. The goodwill balance comprises five reporting units, which had an aggregate carrying amount of $1,105.7 million as of December 31, 2024. There was no goodwill remaining at the Surface Solutions–U.S. Stone reporting unit. An annual assessment of the reporting units for impairment is conducted as of the first day of November. Additionally, more frequent evaluations are undertaken if events or circumstances suggest that the fair value of a reporting unit is likely to be less than its carrying amount. Such events and circumstances may encompass sustained increases in competition, unexpected losses in market share, input costs surpassing projections, disposals of significant components of the business, unforeseen business disruptions (such as those caused by natural disasters or the loss of a customer, supplier, or other significant business relationships), unexpected significant declines in operating results, or substantial adverse changes in the markets in which the entity operates.
 The Company determined that an interim goodwill impairment test was necessary in the third quarter of 2024. While there was no single determinative event or factor, the consideration in totality of several factors, including, among others: (i) the recessionary impacts on residential and commercial markets; (ii) elevated interest rates and home affordability concerns, (iii) the potential for new or modified tariffs on steel and aluminum, and (iv) the decline in home equity borrowings is anticipated to have a considerable effect on the repair and remodel market, led us to conclude that it was more likely than not that the fair values of three of our five reporting units were below their carrying amounts. Additionally, the Company completed its annual goodwill impairment test in the fourth quarter of 2024.
 The impairment test for reporting units involves comparing the estimated fair value of each reporting unit with its carrying amount. Should the carrying amount of a reporting unit exceed its estimated fair value, an impairment loss is recorded. This loss is determined based on the difference between the fair value and the carrying amount of the reporting units, not to exceed the associated carrying amount of goodwill.
 As detailed in Note 6, Goodwill and Intangible Assets, in Item 8, Financial Statements and Supplementary Data, we recorded impairment losses totaling $898.7 million for the year ended December 31, 2024 at our Aperture Solutions–U.S., Surface Solutions–U.S. Siding, and our Shelter Solutions reporting units. These reporting units that were impaired in 2024 were written down to their respective fair values resulting in zero excess fair value over carrying amount as of their latest 2024 impairment testing dates. Accordingly, these and other individual reporting units that have 20% or less excess fair value over carrying amount as of their latest testing date have a heightened risk of future impairments if any assumptions, estimates, or market factors change in the future. Reporting units with a heightened risk of future impairments had an aggregate goodwill carrying amount of $987.5 million at December 31, 2024. Of the $987.5 million with a heightened risk of future impairments, $371.0 million is attributable to Aperture Solutions–U.S. with 0% excess fair value over carrying amount. If any assumptions, estimates, or market factors change in the future, these amounts are also susceptible to impairments.
 Fair value determinations require considerable judgment and are sensitive to changes in underlying assumptions, estimates, and market factors. The discounted cash flow method under the income approach is generally employed to estimate the fair value of the reporting units. Additionally, the guideline public company method and the guideline transaction method are utilized under the market approach. Significant assumptions inherent in estimating fair values include the projected future annual net cash flows for each reporting unit, encompassing net sales, cost of sales, selling, general and administrative expenses, depreciation and amortization, working capital, and capital expenditures. Other critical assumptions involve income tax rates, long-term growth rates, and a discount rate that appropriately reflects the risks inherent in each future cash flow stream.

 The assumptions utilized in financial forecasts are selected based on historical data, supplemented by current and anticipated market conditions, estimated growth rates, management's strategic plans, and guideline companies.
 The discount rates and long-term growth rates employed to estimate the fair values of the reporting units, which had an excess fair value of 20% or less over the carrying amount, along with the sensitivity to changes in the underlying assumptions as of the most recent 2024 impairment testing date for each reporting unit, are detailed as follows (in millions):

 (1) A reduction in fair value would not necessarily cause an impairment in all cases, but due to the low or zero excess fair value over carrying amount for these reporting units, it is reasonably possible that a reduction in fair value would lead to an impairment.
 Assumptions utilized in impairment testing are determined at a specific point in time and necessitate considerable judgment; consequently, they are subject to modification based on the prevailing facts and circumstances at each annual and interim impairment test date. Furthermore, these assumptions are typically interdependent and do not change in isolation. Nevertheless, given the reasonable possibility that changes in assumptions may transpire, as a sensitivity measure, the estimated effects of isolated changes in discount rates and long-term growth rates for reporting units with 20% or less excess fair value over the carrying amount have been presented. If current expectations of future growth rates and margins are not met, if market factors outside of our control, such as discount rates, change, or if management's expectations or plans otherwise change, including as a result of the development of our five-year operating plan, then one or more of our reporting units might become impaired in the future.
 Impairment of Long-Lived Assets
 We review the carrying value of our long-lived assets, including finite-lived intangibles, property, plant, and equipment, and right-of-use assets, for potential impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. The policy ensures that our financial statements reflect the accurate value of our assets and comply with relevant accounting standards. Indicators of impairment may include, but are not limited to:
 • Significant underperformance relative to historical or projected future operating results.
 • Significant changes in the manner of use of the assets or the strategy for the overall business.
 • Significant negative industry or economic trends.
 • Significant decline in the market value of the asset.
 • Legal factors, including changes in regulations affecting the asset.

 We define our asset groups at the lowest level for which identifiable cash flows are largely independent of the cash flows of other groups of assets. Given the importance of the brands, customer relationships, executive and functional management and integrated support services, the Company has defined its asset groups are consistent with our reporting units, which include: Aperture Solutions–U.S., Surface Solutions–U.S. Siding, Surface Solutions–U.S. Stone, Shelter Solutions, Aperture Solutions–Canada, and Surface Solutions–Canada.

 When an indicator of impairment is identified, we perform a recoverability test by comparing the carrying amount of the asset or asset group to the sum of the undiscounted future cash flows expected to result from the use and eventual disposition of the asset. If the carrying amount exceeds the undiscounted cash flows, an impairment loss is recognized. The impairment loss is measured as the amount by which the carrying amount of the asset exceeds its fair value, determined based on the asset's market value, if an active market exists, or future. The impairment loss is recognized in the income statement.
 Fair value is determined based on the asset's market value, if an active market exists, or we use future undiscounted cash flows over the asset's useful life to determine if an asset is impaired. The discount rate is adjusted to reflect risks specific to the asset and the time value of money. The Company believes it uses reasonable and supportable assumptions for future cash flows, including assumptions related to the discount rate.
 The Company completed an assessment of its long-lived assets for impairment given: (i) the completion of the Company's third and fourth quarter results, which were below management's expectations due to several factors such as lower than expected volumes, and (ii) the development and approval of our 2025 annual operating plan in December 2024. As a result of

 this assessment, the Company recognized an impairment loss of $68.7 million related to long-lived assets in its Surface Solutions–U.S. Stone reporting unit. The impairment is included in the Impairment of goodwill, intangible assets and property, plant and equipment line item in the Consolidated Statements of Income (Loss) for 2024 and was allocated to intangible assets of $32.7 million, property, plant and equipment of $24.2 million, and lease right-of-use assets of $11.8 million.
 The impaired assets' revised carrying amounts will be depreciated over their remaining useful lives. The Company will continue to monitor the recoverability of its long-lived assets for its other assets groups and will perform additional impairment tests if events or changes in circumstances indicate that the carrying amount of the assets may not be recoverable.
 The Company assumptions utilized in the impairment testing are determined at a specific point in time and necessitate considerable judgment; consequently, they are subject to modification based on the prevailing facts and circumstances at each balance sheet date. Furthermore, these assumptions are typically interdependent and do not change in isolation.
 Product Warranties
 The Company sells a number of products and offers a number of warranties. The specific terms and conditions of these warranties vary depending on the product sold. As of December 31, 2024, the Company's product warranty liability was $188.3 million, with most of the liability recognized in our Aperture Solutions and Surface Solutions reportable segments. Factors that affect the Company's warranty liabilities include the number of units sold, historical and anticipated rates of warranty claims, cost per claim and new product introduction. Warranties are normally limited to replacement or service of defective components for the original customer. Some warranties are transferable to subsequent owners. Transferable warranties are generally limited to ten years from the date of manufacture or require pro-rata payments from the customer. A provision for estimated warranty costs is recorded based on historical experience and the Company periodically adjusts these provisions to reflect actual experience. The Company assesses the adequacy of the recorded warranty claims and adjusts the amounts as necessary.
 Income Taxes
 The determination of our provision for income taxes requires significant judgment, the use of estimates and the interpretation and application of complex tax laws. The amount recorded in our Consolidated Financial Statements reflects estimates of final amounts due to timing of completion and filing of actual income tax returns. Estimates are required with respect to, among other things, the potential utilization of operating and capital loss carry-forwards for federal, state, and foreign income tax purposes and valuation allowances required, if any, for tax assets that may not be realized in the future. We recognize the tax benefit from an uncertain tax position only if it is more-likely-than-not that the tax position will be sustained on examination by the taxing authorities, based on the technical merits of the position. The tax benefits recognized in the Consolidated Financial Statements from such a position are measured based on the largest benefit that is more-likely-than-not to be realized upon ultimate settlement. We establish allowances when, despite our belief that our tax return positions are fully supportable, certain positions could be challenged, and the positions may not be fully sustained. Our provision for income taxes reflects a combination of income earned and taxed in the various U.S. federal and state, Canadian federal and provincial and other jurisdictions. Jurisdictional tax law changes, increases or decreases in permanent differences between book and tax items, accruals or adjustments of accruals for tax contingencies or valuation allowances, and the change in the mix of earnings from these taxing jurisdictions all affect the overall effective tax rate.
 As of December 31, 2024, the $19.8 million net operating loss carryforward included $10.8 million for U.S federal losses and $9.0 million for U.S. state losses. The state net operating loss carryforwards began to expire in 2024, if unused, and the federal and foreign loss carryforwards will begin to expire in 2030, if unused. There are limitations on the utilization of certain net operating losses.

 Item 7A. Quantitative and Qualitative Disclosures About Market Risk.
 Commodity Prices
 The raw materials used in each of our reportable segments are mainly commodities. Specifically, we use PVC resin, glass and aluminum in our residential products and steel in our commercial products. Prices of these commodities can be influenced by numerous factors including, but not limited to, general economic conditions domestically and internationally, the availability of raw materials, competition, labor costs, freight and transportation costs, production costs, import duties and other trade restrictions. If prices of these raw materials were to increase dramatically, we may not be able to pass such increases on to our customers and, as a result, gross margins could decline significantly. Raw materials are generally available from numerous sources, and the number of suppliers is adequate to support production.
 We manage the exposure to commodity pricing risk by increasing our selling prices for corresponding material cost increases, continuing to diversify our product mix, strategic buying programs and vendor partnering. The market for our products may or may not accept price increases and, as such, there is no assurance that we can maintain margins in an environment of rising commodity prices. See Item 1A- Risk Factors - Price volatility and supply constraints for raw materials could prevent us from meeting delivery schedules to our customers or reduce our profit margins.
 Interest Rates
 We are subject to market risk exposure related to changes in interest rates on our revolving credit facilities and term loans facilities. The following table sets forth the annual impact of a quarter point increase or decrease in interest rates on these facilities assuming the revolving credit facilities are fully drawn:

 In April 2023, we entered into cash flow interest rate swap hedge contracts for a total notional amount of $1.5 billion to mitigate the exposure risk of our floating interest rate debt. The interest rate swaps effectively convert a portion of the floating rate interest payment into a fixed rate payment. See Note 9 — Debt in the Notes to the Consolidated Financial Statements for information on the material terms of our long-term debt and interest rate swaps.
 Foreign Currency Exchange Rates
 The functional currency for our Canadian operations is the Canadian dollar ("CAD"). Translation adjustments resulting from translating the functional currency financial statements into U.S. dollar ("USD") equivalents are reported separately in accumulated other comprehensive (loss) income on the Consolidated Statements of Equity. The net foreign exchange gain (loss) included in net income (loss) in the Consolidated Statements of Income (Loss) was a loss of $14.1 million for 2024 and a gain of $6.8 million for 2023. Net foreign exchange translation loss included in the Consolidated Statements of Comprehensive Income (Loss) were a loss of $15.5 million for 2024 and a loss of $2.8 million for 2023.
 We have entered into foreign currency forward contracts with a financial institution to hedge primarily inventory purchases in Canada, which are not material.

 REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
 To the shareholder and the Board of Directors of Cornerstone Building Brands, Inc.
 Opinion on the Financial Statements
 We have audited the accompanying consolidated balance sheet of Cornerstone Building Brands, Inc. and subsidiaries (the "Company") as of December 31, 2024, the related consolidated statements of (loss) income, comprehensive (loss) income, equity, and cash flows, for the year ended December 31, 2024, and the related notes (collectively referred to as the "financial statements"). In our opinion, the financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2024, and the results of its operations and its cash flows for the year ended December 31, 2024, in conformity with accounting principles generally accepted in the United States of America.
 We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Company's internal control over financial reporting as of December 31, 2024, based on criteria established in Internal Control — Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission and our report dated March 14, 2025, expressed an adverse opinion on the Company's internal control over financial reporting because of a material weakness.
 Basis for Opinion
 These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on the Company's financial statements based on our audits. We are a public accounting firm registered with the 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 and in accordance with auditing standards generally accepted in the United States of America. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the 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 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 financial statements. We believe that our audits provide a reasonable basis for our opinion.
 Critical Audit Matter
 The critical audit matter communicated below is a matter arising from the current-period audit of the financial statements that was communicated or required to be communicated to the audit committee and that (1) relates to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the 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.
 Goodwill Valuation — Refer to Notes 2 and 6 to the financial statements
 Critical Audit Matter Description
 The Company evaluates goodwill for impairment at least annually in the fourth quarter or whenever events occur, or circumstances indicate, that it is more likely than not that the fair value of a reporting unit is below its carrying value. The Company determines the fair value of each reporting unit using both the income and the market approach. The income approach requires management to make a number of business and valuation assumptions for each reporting unit, including assumptions of projected revenues and operating margins, as well as the selection of a discount rate. The market approach requires management to estimate fair value using marketplace fair value data derived from a comparable industry grouping of publicly traded companies and from pricing multiples implied from sales of companies similar to the Company's reporting units ("market multiples").
 We identified the valuation of goodwill for the Aperture Solutions–U.S., Aperture Solutions–Canada, Surface Solutions–U.S. Siding, and Shelter Solutions reporting units as a critical audit matter because the determination of the reporting unit fair values was based on significant assumptions that are sensitive to changes and are dependent on expected future market and

 economic conditions. Auditing the assumptions used by management related to projected revenues and operating margins, as well as the selection of a discount rate required a high degree of auditor judgment and an increased extent of effort, including the need to involve our fair value specialists.
 How the Critical Audit Matter Was Addressed in the Audit
 Our audit procedures related to the Company's assumptions and valuation methodology included the following, among others:
 • We tested the design and operating effectiveness of controls over management's goodwill impairment evaluation, including controls over forecasts of future cash flows based on estimates of revenues, operating margins and the determination of a discount rate, as well as the determination of comparable market multiples.
 • We evaluated the reasonableness of management's forecasts of projected revenue and operating margins by comparing actual results to management's historical forecasts, historical results and third-party industry and peer performance.
 • With the assistance of our fair value specialists, we evaluated the reasonableness of the valuation methodologies, the discount rates, and the industry pricing multiples by performing certain procedures, including:
 –Evaluating whether the fair value models being used are appropriate considering the Company's circumstances and valuation premise identified
 –Developing an independent range using market inputs to assess the discount rate utilized
 –Evaluating the market multiples by considering the selected comparable industry grouping of publicly traded companies
 –Testing the underlying source information and mathematical accuracy of the calculations

 NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 (Amounts in thousands, except share and per share data, unless otherwise noted)

 Note 1 — Basis of Presentation
 Description of Business
 Cornerstone Building Brands, Inc. ("Cornerstone Building Brands" or, collectively with its subsidiaries, unless the context requires otherwise, the "Company") is a holding company incorporated in the State of Delaware. The Company is a leading exterior building products manufacturer by sales in North America and serves residential and commercial customers across new construction and the repair and remodel end markets. The Company is organized in three reportable segments: Aperture Solutions, Surface Solutions and Shelter Solutions.

 Organization and Ownership Structure
 On July 25, 2022 and pursuant to an Agreement and Plan of Merger dated March 5, 2022 (the "Merger Agreement") by and among the Company, Camelot Return Intermediate Holdings, LLC ("Camelot Parent") and Camelot Return Merger Sub, Inc. ("Merger Sub"), investment funds managed by Clayton, Dubilier and Rice, LLC ("CD&R") became the indirect owners of all the issued and outstanding shares of common stock of Cornerstone Building Brands. Pursuant to the Merger Agreement, Merger Sub merged with and into the Company (the "Merger"), with the Company surviving the Merger as a subsidiary of Camelot Parent (the "Surviving Corporation"). At the effective time of the Merger (the "Effective Time"), the Company became a privately held company and its shares were no longer traded on the New York Stock Exchange.
 At the Effective Time, in accordance with the terms and conditions set forth in the Merger Agreement, each share of Company common stock outstanding immediately prior to the Effective Time of the Merger (other than (i) shares of Company common stock that were cancelled or converted into shares of common stock of the Surviving Corporation in accordance with the Merger Agreement and (ii) shares of Company common stock held by stockholders of the Company (other than CD&R, certain investment funds managed by CD&R and other affiliates of CD&R that held shares of Company common stock) who did not vote in favor of the Merger Agreement or the Merger and who had perfected and not withdrawn a demand for appraisal rights pursuant to Section 262 of the General Corporation Law of the State of Delaware), was converted into the right to receive cash in an amount equal to $ 24.65 in cash per share, without interest and subject to any required withholding taxes.
 On July 25, 2022, the Company amended its Certificate of Incorporation to authorize 1,000 shares of common stock, par value of $ 0.01. Each share of common stock will have one vote and all shares of common stock vote together as a single class.
 Basis of Presentation
 The accompanying consolidated financial statements are presented in conformity with accounting principles generally accepted in the United States of America ("U.S. GAAP") and pursuant to the rules and regulations of the Securities and Exchange Commission ("SEC"). The accompanying Consolidated Financial Statements include the accounts and operations of the Company and its majority-owned subsidiaries and all adjustments (consisting of normal recurring adjustments) that the Company considered necessary to present a fair statement of its results of operations, financial position and cash flows. All intercompany accounts and transactions have been eliminated in consolidation. Through application of pushdown accounting, the Company's Consolidated Financial Statements are presented as Predecessor for periods prior to the Merger and Successor for subsequent periods. The years ended December 31, 2024 and December 31, 2023 and the period from July 25, 2022 through December 31, 2022, represent Successor periods and the period from January 1, 2022 through July 24, 2022, represent the Predecessor period. All references herein for the year "2024" represents the year ended December 31, 2024 and "2023" represent the year ended December 31, 2023. Certain items have been reclassified in the prior year disclosures to conform to the current year presentation.

 Note 2 — Significant Accounting Policies
 Use of Estimates
 The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, net sales and expenses, and related disclosures of contingent assets and liabilities in the Consolidated Financial Statements and accompanying notes. These estimates include, but are not limited to: establishing the allowance for expected credit losses; allowance for slow-moving and obsolete inventory; the impairment of goodwill; establishing useful lives for and evaluating the recovery of our finite-life, long-lived assets; recognizing the fair value of assets acquired and liabilities assumed in business combinations; determining the fair value of contingent considerations, accounting for rebates and product warranties; the valuation and expensing for share-based compensation; certain assumptions made in accounting for pension benefits; accounting for contingencies and uncertainties and accounting for income taxes. Actual results may differ from the estimates used in preparing the Consolidated Financial Statements.
 Cash, Cash Equivalents
 Cash and cash equivalents mainly consist of highly liquid, unrestricted savings, checking, money market funds with maturities of less than three months and other bank accounts.
 The following table sets forth the components of cash and cash equivalents:

 Accounts Receivable, Net
 The Company reports accounts receivable net of an allowance for expected credit losses. The Company's allowance for expected credit losses was $ 26.3 million at December 31, 2024 and $ 9.6 million at December 31, 2023. The allowance was written off on July 25, 2022, in connection with the Merger and is presently being reestablished with an offset to gross receivables to accurately reflect the ongoing potential for future losses. The Company establishes provisions for expected credit losses based on the Company's assessment of the collectability of amounts owed to the Company by its customers. Such allowances are included in selling, general and administrative expenses in the Company's Consolidated Statements of Income (Loss). In establishing the allowance, the Company considers changes in the financial position of a customer, age of the accounts receivable balances, availability of security, unusual macroeconomic conditions, lien rights and bond rights as well as disputes, if any, with its customers. Uncollectible accounts are written off when a settlement is reached for an amount that is less than the outstanding historical balance, all collection efforts have been exhausted or any legal action taken by the Company has concluded. The Company's provision for expected credit losses was $ 8.3 million for 2024, $ 8.2 million for 2023, $ 2.1 million for the period from July 25, 2022 through December 31, 2022, and $ 3.8 million for the period from January 1, 2022 through July 24, 2022.

 Inventories
 Inventories are stated at the lower of cost or net realizable value less allowance for slow-moving and obsolete inventory using the first-in, first-out method. The Company reduces its inventory value for estimated slow-moving and obsolete inventory when evidence exists that the net realizable value of inventory is lower than its cost. The Company's allowance for slow-moving and obsolete inventory was $ 34.3 million at December 31, 2024 and $ 0.4 million at December 31, 2023. The allowance was written off on July 25, 2022, in connection with the Merger and is presently being reestablished with an offset to gross inventory to accurately reflect the ongoing potential for future losses. The Company's estimate is based upon multiple factors including, but not limited to: (i) historical write-offs and usage, (ii) sales of products at discounted or negative margins, (iii) discontinued products or designs, (iv) specific inventory quantities that are more than estimated future demand and (v) other market conditions. The Company's provision for slow-moving and obsolete inventory was $ 10.4 million for 2024, $ 1.9 million for 2023, $ 3.8 million for the period from July 25, 2022 through December 31, 2022, and $ 7.2 million for the period from January 1, 2022 through July 24, 2022.

 Interest Rate Swaps
 The Company's use of derivative instruments, principally interest rate swaps, is limited to non-trading purposes and is designed to partially manage exposure to changes in interest rates. The Company's contracts are hedges for transactions with notional amounts and periods consistent with the related exposures and do not constitute investments independent of these exposures.
 The changes in the fair value (i.e., gains or losses) of a derivative instrument are recorded as either assets or liabilities in our Consolidated Balance Sheets with an offset to net income (loss) or other comprehensive income (loss) depending on whether, for accounting purposes, it has been designated and qualifies as an accounting hedge and, if so, on the type of hedging relationship. The criteria used to determine if hedge accounting treatment is appropriate are: (a) formal designation and documentation of the hedging relationship, the risk management objective and hedging strategy at hedge inception; (b) eligibility of hedged items, transactions and corresponding hedging instrument; and (c) effectiveness of the hedging relationship both at inception of the hedge and on an ongoing basis in achieving the hedging objectives. For those derivative instruments designated and qualifying as hedging instruments, the Company must designate the hedging instrument either as a fair value hedge or as a cash flow hedge. The Company designates its interest rate contracts for forecasted interest payments as cash flow hedges. The Company had no hedging instruments designated as fair value hedges.
 For interest rate swaps designated and qualifying as cash flow hedges, the Company recognizes gains or losses as a component of other comprehensive income (loss) and reclassified into earnings in the same period or periods during which the hedged transaction affects earnings. Cash flows from hedging activities are classified as operating activities in the Consolidated Statement of Cash Flows.
 Property, Plant and Equipment, Net
 Property, plant and equipment is carried at cost. Depreciation is provided on a straight-line basis, over the estimated useful lives of the assets. Gains or losses resulting from dispositions are included in operating income. Betterments and renewals, which improve and extend the life of an asset, are capitalized; maintenance and repair costs are expensed as incurred. Assets held for use to be disposed of at a future date are depreciated over the remaining useful life. Assets to be sold are written down to fair value less costs to sell at the time the assets are being actively marketed for sale. Depreciation and amortization are recognized in cost of sales or selling, general and administrative expenses based on the nature and use of the underlying assets.
 Intangible Assets, Net
 Intangible assets acquired separately are measured initially at cost. The cost of intangible assets acquired in a business combination is their fair value at the acquisition date. After initial recognition, intangible assets are carried at cost less any accumulated amortization and any accumulated impairment losses.
 The Company's intangible assets have finite useful lives and are amortized on a straight-line basis over their estimated useful lives. The amortization period and the amortization method for an intangible asset with a finite useful life are reviewed at least at each financial year-end. Changes in the expected useful life or the expected pattern of consumption of future economic benefits embodied in the asset are accounted for by changing the amortization period or method, as appropriate, and are treated as changes in accounting estimates. The amortization expense on intangible assets with finite lives is recognized in the Company's Consolidated Statement of (Loss) Income.
 An intangible asset is derecognized on disposal or when no future economic benefits are expected from its use or disposal. Gains or losses arising from derecognition of an intangible asset, measured as the difference between the net disposal proceeds and the carrying amount of the asset, are recognized in profit (loss) when the asset is derecognized.
 Impairment of Long-Lived Assets
 The Company evaluates long-lived assets for impairment, including, but not limited to, property, plant and equipment, lease right-of-use assets, and finite-lived intangible assets, when events or changes in circumstances indicate that the carrying value of such assets may not be recoverable or the assets are being held for sale. Upon the occurrence of a triggering event, the asset is reviewed to assess whether the estimated undiscounted cash flows expected from the use of the asset plus the residual value from the ultimate disposal exceeds the carrying value of the asset. If the carrying value exceeds the estimated recoverable amounts, the asset is written down to the estimated fair value and any resulting impairment loss is reflected within other operating costs on the Consolidated Statements of Income (Loss). The Company recognized an impairment loss of $ 68.7 million related to long-lived assets in its Surface Solutions–U.S. Stone asset group. The impairment was included in

 the Impairment of goodwill, intangible assets and property, plant and equipment line item in the Consolidated Statements of Income (Loss) for the year ended December 31, 2024, and was allocated to intangible assets of $ 32.7 million, property, plant and equipment of $ 24.2 million, and lease right-of-use assets of $ 11.8 million. There were no meaningful impairments prior to the year ended December 31, 2024.
 Goodwill represents the excess of the purchase price over the fair value of identifiable net assets acquired in business combinations. The Company evaluates goodwill for impairment at least annually and completes its annual review in the fourth quarter. When evaluating goodwill for impairment, the Company estimates the fair value of its reporting units. If the carrying amount of a reporting unit, including goodwill, exceeds the estimated fair value, then the excess is charged to earnings as an impairment loss. Significant judgment is required in estimating the fair value of the reporting unit and performing goodwill impairment tests. The determination of fair value incorporates significant unobservable inputs. The Company records goodwill adjustments for changes to the purchase price allocation prior to the end of the measurement period, which is not to exceed one year from the acquisition date.
 We have six reporting units defined as "Aperture Solutions–U.S.," "Aperture Solutions–Canada," "Surface Solutions–U.S. Siding," "Surface Solutions–Canada," "Surface Solutions–U.S. Stone" and "Shelter Solutions." Aperture Solutions–U.S. and Aperture Solutions–Canada reporting units are part of the Aperture Solutions reportable segment. Surface Solutions–U.S. Siding, Surface Solutions–Canada and Surface Solutions–U.S. Stone are part of the Surface Solutions reportable segment. Shelter Solutions is a reporting unit and a reportable segment.
 The Company recorded impairments relating to goodwill of $ 866.1 million during 2024, related to its Aperture Solutions–U.S. reporting unit totaling $ 496.1 million, its Surface Solutions–U.S. Siding reporting unit of $ 329.1 million, and its Surface Solutions–U.S. Stone reporting unit of $ 40.8 million. The impairment was included in the Impairment of goodwill, intangible assets and property, plant and equipment line item in the Consolidated Statements of Income (Loss). The Company did not recognize any impairments of goodwill for any of the periods presented prior to the year ended December 31, 2024.
 Product Warranties
 The Company offers a number of warranties associated with the products it sells. Warranties are normally limited to replacement or service of defective components for the original customer. Some warranties are transferable to subsequent owners and are generally limited to ten years from the date of manufacture. The Company accrues for the estimated cost of product warranty at the time of sale based on historical experience and expectations regarding future costs to be incurred. Warranty costs are included within cost of sales.
 Leases
 The Company has leases for certain manufacturing sites; warehouse and distribution locations; offices; and vehicles and equipment. Many of these leases have options to terminate prior to or extend beyond the end of the term. The exercise of the majority of lease renewal options is at the Company's sole discretion. Some lease agreements have variable payments, the majority of which are real estate agreements in which future increases in rent are based on an index. The Company's lease agreements do not contain any material residual value guarantees or material restrictive covenants. The Company accounts for lease and non-lease components as a single lease component. The Company has elected to exclude leases with an initial term of 12 months or less from the Consolidated Balance Sheets and recognizes related lease payments in the Consolidated Statements of Income (Loss) on a straight-line basis over the lease term.
 Operating lease liabilities are recognized based on the present value of the future minimum lease payments over the reasonably expected holding period at the commencement date of the leases. Few of the Company's lease contracts provide a readily determinable implicit rate. As such, an estimated incremental borrowing rate is utilized, based on information available at the inception of the lease. The incremental borrowing rate represents an estimate of the interest rate we would incur at lease commencement to borrow an amount equal to the lease payments on a collateralized basis over the term of the lease.
 Accounting for leases requires judgment, including determining whether a contract contains a lease, the incremental borrowing rates to utilize for leases without a stated implicit rate, the reasonably certain holding period for a leased asset, and the allocation of consideration to lease and non-lease components.

 Long-term Debt Discounts, Issuance Costs and Fair Value Adjustments
 Unamortized discounts, debt issuance costs and fair value adjustments incurred relating to long-term debt are amortized over the term of the related financing using the effective interest method.

 Revenue Recognition
 The Company enters into contracts that pertain to products, which are accounted for as separate performance obligations and are typically one year or less in duration. Given the nature of the Company's sales arrangements, the Company is not required to exercise significant judgment in determining the timing for the satisfaction of performance obligations or the transaction price. Revenue is measured as the amount of consideration expected to be received in exchange for the Company's products. Revenue is recognized when obligations under the terms of a contract with our customers are satisfied; generally, this occurs with the transfer of control of our products at a point in time. Allowances for cash discounts, volume rebates and other customer incentive programs, as well as gross customer returns, among others, are recorded as a reduction of sales at the time of sale based upon the estimated future outcome.
 The Company's net sales are adjusted for variable consideration, which includes customer volume rebates, special pricing discounts, prompt payment discounts, customer returns and other incentive programs. The Company measures variable consideration by estimating expected outcomes using analysis and inputs based upon anticipated performance, historical data, and current and forecasted information. Measurement of variable consideration is reviewed by management periodically and net sales are adjusted accordingly. The Company does not have significant financing components.
 Shipping and handling activities billed to customers are treated as fulfillment costs. Shipping and handling activities performed before a customer obtains control of the product are not treated as a separate performance obligation and are included in net sales at the same point in time the related product revenue is recognized, while shipping and handling costs are expensed as incurred and recorded within in cost of sales in the Company's Consolidated Statements of Income (Loss).

 A portion of the Company's net sales within the Shelters Solutions reportable segment includes the offering of extended warranties, which customers can purchase separately from the related products. These extended warranties are considered separate performance obligations, with warranty options available for 5, 10, 15 or 20 years. Revenue allocated to these warranties is recognized on a straight-line basis over the warranty period, reflecting the pattern in which the Company expects to satisfy the performance obligation.
 For 2024, one customer accounted for 12.2 % of the Company's net sales. The sales attributed to this customer are included in all three of the Company's reportable segments.
 Advertising Costs
 Advertising costs are expensed as incurred. Advertising expense was $ 18.2 million for 2024, $ 15.9 million for 2023, $ 11.3 million for the period from July 25, 2022 through December 31, 2022 and $ 11.1 million for the period from January 1, 2022 through July 24, 2022. These costs are included in selling, general and administrative expenses on the Consolidated Statements of Income (Loss).
 Share-Based Compensation
 Share-based compensation expense, measured as the fair value of an award on the date of grant. For time-based awards, expense is recorded over the requisite service or performance period. For awards with performance conditions, the amount of share-based compensation expense recognized is based upon the probable outcome of the performance conditions, as determined by the Company. The Company accounts for forfeitures of outstanding but unvested awards in the period they occur.
 Income Taxes
 Deferred income tax assets and liabilities are measured based on differences between the financial statement basis and income tax basis of assets and liabilities using estimated income tax rates expected to be in effect for the year in which the differences are expected to reverse. Changes in deferred income tax assets and liabilities attributable to changes in enacted income tax rates are charged or credited to income tax expense. Valuation allowances are established when necessary to reduce deferred income tax assets to the amount that is more-likely-than-not to be realized.
 The Company assesses its income tax positions and records tax benefits based upon management's evaluation of the facts, circumstances, and information available at the reporting date. The Company recognizes tax benefits from uncertain tax

 positions only if it is more-likely-than-not that the tax position will be sustained on examination by the taxing authorities, based on technical merits of the positions. The tax benefits recognized from such a position are measured based on the largest benefit that is more-likely-than-not to be realized upon ultimate settlement.
 Foreign Currency Remeasurement and Translation
 Gains (losses) arising from transactions denominated in a currency other the functional currency of the entity that is party to the transaction are included in net (loss) income on the Company's Consolidated Statements of Income (Loss), including the remeasurement of foreign denominated intercompany loans at current exchange rates.
 The Company's reporting currency is the United States ("U.S.") dollar while the functional currency of the Company's significant non-U.S. subsidiaries is the Canadian Dollar. Translation adjustments resulting from translating the functional currency financial statements into U.S. dollar equivalents are reported separately in accumulated other comprehensive income (loss) in equity.
 Business Combinations
 We account for business combinations under the acquisition method of accounting, which requires an allocation of the consideration we paid to the identifiable assets, intangible assets and liabilities based on the estimated fair values as of the closing date of the acquisition. The excess of the fair value of the purchase price over the fair values of these identifiable assets, intangible assets and liabilities is recorded as goodwill.
 Acquired intangibles other than goodwill are initially recognized at fair value and amortized over their useful lives unless those lives are determined to be indefinite. The fair value of identifiable intangible assets is determined using an income approach on an individual asset basis. Specifically, we use the multi-period excess earnings method to determine the fair value of customer relationships and the relief-from-royalty approach to determine the fair value of trade names. Determining the fair value of acquired intangibles involves significant estimates and assumptions, including forecasted revenue growth rates, margins, percentage of revenue attributable to the trade name, contributory asset charges, customer attrition rate, market-participant discount rates, the assumed royalty rates and income tax rates.

 The determination of the useful life of an intangible asset other than goodwill is based on factors including historical trade name performance with respect to consumer name recognition, geographic market presence, market share, plans for ongoing trade name support and promotion, customer attrition rate, and other relevant factors.

 The initial purchase price allocation is based upon provisional information and is subject to revision during the measurement period (up to one year from the acquisition date) as additional information concerning valuations is obtained. As the Company obtains new information regarding facts and circumstances that existed as of the acquisition date that, if known, would have resulted in revised estimated values of those assets or liabilities, the Company will accordingly revise the provisional purchase price allocation. These adjustments may include, but are not limited to, adjustments pertaining to intangible assets acquired, property, plant and equipment acquired, tax liabilities assumed and working capital. The associated acquisitions expenses are expensed as incurred in selling, general and administrative expenses within the Consolidated Statements of Income (Loss).

 Contingencies
 The Company's contingent liabilities are related primarily to litigation and environmental matters and are based upon assumptions and estimates regarding the probable outcome of the matter. The Company records the probability by evaluating historical precedent as well as the specific facts relating to each particular contingency (including the opinion of outside advisors, professionals and experts). The Company records loss contingencies and unasserted claims when it believes a loss is probable and the amount of the loss can be reasonably estimated. The ultimate losses incurred upon final resolution of loss contingencies may differ materially from the estimated liability recorded at any particular balance sheet date.

 In November 2023, the FASB issued ASU No. 2023-07, Improvements to Reportable Segment Disclosures (Topic 280). This ASU updates reportable segment disclosure requirements by requiring disclosures of significant reportable segment expenses that are regularly provided to the Chief Decision Maker ("CODM") and included within each reported measure of a segment's profit or loss. This ASU also requires disclosure of the title and position of the individual identified as the CODM and an explanation of how the CODM uses the reported measures of a segment's profit or loss in assessing segment

 performance and deciding how to allocate resources. The ASU is effective for annual periods beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024. Adoption of the ASU should be applied retrospectively to all prior periods presented in the financial statements. The Company adopted this policy as of January 1, 2024. See disclosures in Note 18 — Reportable Segment and Geographical Information.
 In December 2023, the FASB issued ASU No. 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures, which establishes new income tax disclosure requirements in addition to modifying and eliminating certain existing requirements. The new guidance requires consistent categorization and greater disaggregation of information in the rate reconciliation, as well as further disaggregation of income taxes paid. This change is effective for annual periods beginning after December 15, 2024. Prospective application is required, with retrospective application permitted. The Company is currently evaluating the effect the updated guidance will have on its financial statement disclosures.
 In November 2024, the FASB issued ASU No. 2024-03, Income Statement- Reporting Comprehensive Income- Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses, which improves disclosure requirements and provides more detailed information about an entity's expenses, specifically amounts related to purchases of inventory, employee compensation, depreciation, intangible asset amortization and selling expenses, along with qualitative descriptions of certain other types of expenses. This change is effective for annual periods beginning after December 15, 2026 and interim periods within fiscal years beginning after December 15, 2027. The Company is currently evaluating the effect the updated guidance will have on its financial statement disclosures.

 Note 3 — Mergers, Acquisitions and Divestitures
 CD&R Merger Transaction
 On July 25, 2022, Merger Sub merged with and into the Company, with the Company surviving the merger as a subsidiary of Camelot Parent. CD&R previously held 61.9 million shares of the Company immediately prior to the Merger. As a result of the Merger, CD&R became the indirect owners of all of the issued and outstanding shares of Company common stock that CD&R did not already own.

 The Merger was accounted for as a business combination. The purchase price was allocated to the assets acquired and liabilities assumed based on the estimated fair market value at the date of the Merger.

 The Merger was funded in part with proceeds from the following issuances:
 •$ 300.0 million aggregate principal amount under the Side Car Term Loan Facility, due August 2028 (as defined in Note 9 — Debt);
 •$ 710.0 million of 8.750 % Senior Secured Notes (as defined in Note 9 — Debt) due August 2028;
 •$ 564.4 million of cash from the Company;
 •$ 464.4 million aggregate principal amount of 2.99 % senior payment-in-kind notes due 2029 that were issued and are held by Camelot Return Parent, LLC ("Camelot Return Parent"), an indirect parent of Company; and
 •$ 195.0 million from preferred shares of Camelot Return Parent.
 Neither the Company nor any of its subsidiaries is a guarantor of or is obligated to make any payments related to the 2.99 % senior payment-in-kind notes due 2029 held by Camelot Return Parent.

 The Company incurred transaction costs of $ 29.4 million associated with the Merger, of which $ 0.7 million was recognized in the period from July 25, 2022 through December 31, 2022 and $ 28.7 million was recognized in the period from January 1, 2022 through July 24, 2022. These costs are included in selling, general and administrative expenses on the Consolidated Statements of (Loss) Income.
 During July 2023, the Company completed measurement period adjustments, which were mainly composed of a $ 291.5 million increase to property, plant and equipment and a $ 174.7 million decrease to intangible assets. The effect of measurement period adjustments on the estimated fair value elements were reflected as if the adjustments had been made as of the date of the Merger, including a $ 66.5 million cumulative catch-up to depreciation and amortization expense recorded during the three months ended July 1, 2023 resulting from the update in the fair market value of property, plant and equipment and intangible assets.

 Acquisitions Completed During 2023
 In December 2023, the Company completed the acquisition of the Eastern Architectural Systems ("EAS") business, whose operations are included in the Company's Aperture Solutions reportable segment. EAS is based in Ft. Myers, Florida and manufactures custom-made aluminum and vinyl impact windows and doors. In August 2023, the Company completed the acquisition of M.A.C. M tal Architectural Inc. ("MAC Metal"), which became an indirect wholly-owned subsidiary of the Company. Headquartered in Saint-Hubert, Quebec, MAC Metal serves the North American residential and commercial markets with high-end steel siding and roofing products. MAC Metal is included in the Company's Surface Solutions reportable segment.
 The total purchase price for these acquisitions was $ 235.5 million, comprised of upfront cash payments of $ 217.7 million and earn-out contingent consideration of $ 16.8 million related to the MAC Metal transaction. The purchase price of these acquisitions was allocated to the assets acquired and liabilities assumed, which related primarily to inventory of $ 15.9 million, property, plant and equipment of $ 21.3 million, goodwill of $ 82.5 million, intangible assets such as, customer lists and trademarks, of $ 73.4 million and $ 34.3 million, contingent consideration of $ 16.8 million, warranty liabilities of $ 5.9 million and noncurrent deferred income tax liabilities of $ 12.3 million. The goodwill recorded is a result of expected synergies and other benefits that we believe will result from the integration of the acquisitions with our operations. Purchase accounting for these acquisitions was finalized during the year ended December 31, 2024.
 The MAC Metal acquisition earn-out is payable over two consecutive twelve-month periods, with the first period starting in the month following the close of the applicable acquisition and payments are based upon achieving certain adjusted EBITDA-based metrics, as defined in the purchase agreement. There was an increase of $ 3.8 million in contingent consideration in 2024, included the impact of exchange rates. The total of $ 21.1 million is recognized in other current liabilities on our Consolidated Balance Sheets at December 31, 2024.
 Unaudited Pro Forma Financial Information
 Pro Forma financial information has not been presented related to the Merger or subsequent acquisitions as this information was not and is not material to the Company's overall consolidated financial statements during the periods presented.
 Divestiture of Coil Coatings
 In June 2022, the Company completed the sale of the coil coatings business to BlueScope Steel Limited for initial cash proceeds of $ 500.0 million, subject to working capital and other customary adjustments. In connection with the transaction, the Company entered into long-term supply agreements to secure a continued supply of light gauge coil coating and painted hot roll steel. For the period from January 1, 2022 through July 24, 2022, the Company recognized a pre-tax gain of $ 394.2 million for the coil coatings divestiture, which is included in gain on divestitures in the Consolidated Statements of Income (Loss).

 (3) Other includes insignificant out-of-period corrections totaling $ 14.9 million, which related to matters that existed as of the date of the Merger.
 Goodwill is comprised of five reporting units, which had an aggregate carrying amount of $ 1,105.7 million as of December 31, 2024. Under the Company's policy, our assessment for impairment of these reporting units is conducted as of the first day of November each year. Additionally, the Company completes more frequent evaluations if events or circumstances suggest that there are indicators of potential impairment. Such events and circumstances encompass, among other potential items, sustained increases in competition, unexpected losses in market share, input costs surpassing projections, disposals of significant components of the business, unforeseen business disruptions (such as those caused by natural disasters or the loss of a customer, supplier, or other significant business relationships), unexpected significant declines in operating results, or substantial adverse changes in the markets in which the entity operates.
 The Company determined that an interim goodwill impairment test was necessary in the third quarter of 2024. While there was no single determinative event or factor, the consideration in totality of several factors, including, among others: (i) the recessionary impacts on residential and commercial markets; (ii) elevated interest rates and home affordability concerns, (iii) the potential for new or modified tariffs on steel and aluminum, and (iv) the decline in home equity borrowings is anticipated to have a considerable effect on the repair and remodel market, led us to conclude that it was more likely than not that the fair values of three of our five reporting units were below their carrying amounts. Additionally, the Company completed its annual goodwill impairment test in the fourth quarter of 2024.
 As a result of completing the impairment tests, the Company recognized non-cash impairment losses totaling $ 866.1 million in 2024, with $ 382.8 million in the quarter ended September 28, 2024 and $ 483.3 million in the quarter ended December 31, 2024. These impairment charges were recorded in the Impairment of goodwill, intangible assets and property, plant and equipment line in the Consolidated Statements of Income (Loss) and related to the following reporting units: (i) Aperture Solutions–U.S., totaling $ 496.1 million, (ii) Surface Solutions–U.S. Stone, totaling $ 40.8 million, and (iii) Surface Solutions–U.S. Siding, totaling $ 329.1 million, reporting units. After recording these impairment charges, there is no goodwill remaining at Surface Solutions–U.S. Stone. No goodwill impairment charges were recorded prior to or during 2023.

 The Company employed a quantitative methodology to determine the fair value of its reporting units. This was achieved by assigning equal weight to the discounted cash flow method under the income approach, designated as a Level 3 measurement, and the market approach, designated as a Level 2 measurement. Under the market approach, the Company implemented both the guideline public company method and the guideline transaction method.
 Fair value determinations require considerable judgment and are sensitive to changes in underlying assumptions, estimates, and market factors. Estimating the fair value of individual reporting units requires us to make assumptions and estimates regarding our future plans, as well as industry and economic conditions. These assumptions and estimates include estimated future annual net cash flows, income tax rates, discount rates, growth rates, and other market factors. If current expectations of future growth rates and margins are not met, if market factors outside of our control, such as discount rates change, or if management's expectations or plans otherwise change, including as a result of the development of our five-year operating plan, then one or more of our reporting units might become impaired in the future. Our reporting units that were impaired in 2024 were written down to their respective fair values resulting in zero excess fair value over carrying amount as of their latest 2024 impairment testing dates. Accordingly, our Aperture Solutions–U.S., Surface Solutions–U.S. Siding, and Shelter Solutions reporting units that have 20 % or less excess fair value over carrying amount as of their latest testing date have a heightened risk of future impairments if any assumptions, estimates, or market factors change in the future. Reporting units with a heightened risk of future impairments had an aggregate goodwill carrying amount of $ 987.5 million as of December 31, 2024. If any assumptions, estimates, or market factors change in the future, these amounts are also susceptible to impairments.

 Note 10 — Employee Benefit Plans

 The basis used to determine the expected long-term rate of return on assets assumptions for the defined benefit plan was recent market performance and historical returns. The investment policy is to maximize the expected return for an acceptable level of risk. Our expected long-term rate of return on plan assets is based on a target allocation of assets, which is based on our goal of earning the highest rate of return while maintaining risk at acceptable levels.

 As of December 31, 2024, our defined pension plan had a projected benefit obligation in excess of the fair value of plan assets. The following table sets forth the changes in the projected benefit obligation, plan assets and funded status, and the amounts recognized on the Consolidated Balance Sheets:

 The principal investment objectives are to ensure the availability of funds to pay pension and postretirement benefits as they become due under a broad range of future economic scenarios, to maximize long-term investment return with an acceptable level of risk based on our pension and postretirement obligations, and to be sufficiently diversified across and within the capital markets to mitigate the risk of adverse or unexpected results from one security class having an unduly detrimental impact on the entire portfolio. Each asset class has broadly diversified characteristics. Decisions regarding investment policy are made with an understanding of the effect of asset allocation on funded status, future contributions and projected expenses.

 Defined Contribution Plan
 The Company has a 401(k) profit sharing plan that allows participation by all eligible employees. The Company's contributions vary, but are based primarily on each participant's level of contributions, which cannot exceed the maximum allowable for income tax purposes. The Company's contribution expense for matching contributions to the plan was $ 19.5 million for 2024, $ 16.1 million for 2023, $ 6.6 million for the period from July 25, 2022 through December 31, 2022 and $ 10.2 million for the period from January 1, 2022 through July 24, 2022.

 Note 11 — Share-based Compensation
 Merger Transaction
 In connection with the Merger in July 2022, under which Cornerstone Building Brands became a privately held company, unvested share-based compensation awards that were previously granted to key employees and executives were cancelled and converted into a contingent contractual right to receive a cash payment from the Company upon vesting. The Company had $ 0.6 million at December 31, 2024 and $ 27.6 million at December 31, 2023 classified as a current liability within employee-related liabilities and $ 1.2 million at December 31, 2023 classified as other long-term liabilities on its Consolidated Balance Sheets. The Company paid out $ 24.7 million of cash to settle Pre-Merger Awards in March 2024.
 The Company recognized an expense of $ 1.4 million for the year ended December 31, 2024 and an expense of $ 16.6 million in the year ended December 31, 2023. For the period from July 25, 2022 through December 31, 2022, the amount of expense recognized was $ 21.9 million. These amounts are included in selling, general and administrative expense on the Consolidated Statements of Income (Loss). As of December 31, 2024 the Company estimates that unrecognized expense is expected to be recognized over a weighted-average period 0.6 years of totaling $ 0.2 million.
 Incentive Units
 Beginning in 2022, pursuant to an incentive unit grant agreement, certain participants were granted incentive units in Camelot Return Ultimate, LP (the "Partnership" or "Camelot Parent"). The incentive units provide the holder with the opportunity to receive, upon certain vesting events and subject to Partnership repurchase rights and conditions, a return based upon the appreciation of the Partnership's equity value from the date of grant. The incentive units vest over a five-year period on a straight-line basis. In 2024, 0.1 million incentive units were granted at an average grant date fair value of $ 43.46 per incentive unit and 0.1 million forfeitures during the period. In 2023, 0.2 million units were granted with 0.1 million in forfeitures. The Company recognized an expense from incentive units of $ 6.2 million in 2024, and $ 8.3 million in 2023. For the period from July 25, 2022 through December 31, 2022, the amount of expense recognized was $ 2.3 million. These amounts are included in selling, general and administrative expense on the Consolidated Statements of Income (Loss). The Company estimates that the unrecognized expense is expected to be recognized over a weighted-average period of 3.1 years totaling $ 22.5 million.

 The Company will recognize compensation cost for the awards on a straight-line basis over a five-year vesting period based on the fair value of the award at the date of grant. The fair value of each option grant is estimated on the grant date using the Black-Scholes option-pricing model, and the following weighted average assumptions:

 Upon a sale of the Partnership, vesting of incentive units will accelerate, subject to the participant's continued employment through the consummation of such sale unless there is non-cash consideration and the incentive units are replaced with awards that have substantially equivalent or better rights.

 The Company carries out its business operations mainly through legal entities in the U.S., Canada and Mexico where we are subject to U.S., state and foreign tax laws. We are subject to income tax audits in multiple jurisdictions.
 As of December 31, 2024, the $ 19.8 million net operating loss carryforward included $ 10.8 million for U.S federal losses and $ 9.0 million for U.S. state losses. Federal net operating losses will begin to expire in 2030, if unused, and state operating losses began to expire in 2024, if unused. There are limitations on the utilization of certain net operating losses.

 Despite the Company's expectation that its tax return positions are consistent with applicable tax laws, the Company understands that certain positions could be challenged by taxing authorities. The Company's tax liability reflect the difference between the tax benefit claimed on tax returns and the amount recognized in the consolidated financial statements. These allowances have been established based on management's assessment as to potential exposure attributable to permanent differences and interest and penalties applicable to both permanent and temporary differences. The tax allowances are reviewed periodically and adjusted in light of changing facts and circumstances, such as progress of tax audits, lapse of applicable statutes of limitations and changes in tax law. The Company is currently under examination by various taxing authorities.
 As of December 31, 2024, the reserve was $ 2.5 million, which includes interest and penalties of $ 1.3 million and is recorded in other long-term liabilities in the accompanying Consolidated Balance Sheets. Of this amount, $ 1.2 million, if recognized would have an impact on the Company's effective tax rate. Interest and penalties were $ 1.3 million for 2024, $ 1.4 million for 2023, $ 0.2 million for the period from July 25, 2022 through December 31, 2022 and $ 0.6 million for the period from January 1, 2022 through July 24, 2022. The Company has elected to treat interest and penalties on unrecognized tax benefits as income tax expense in its Consolidated Statement of (Loss) Income.

 Note 13 — Fair Value of Financial Instruments and Fair Value Measurements
 The Company measures certain financial assets and liabilities at fair value on a recurring basis. Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The Company uses a three-level hierarchy for fair value measurements based on the observability of inputs to the valuation of an asset or liability as of the measurement date. The three levels of the fair value hierarchy are as follows:

 • Level 1 – Quoted prices (unadjusted) in active markets for identical assets or liabilities.

 • Level 2 – Inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly.
 • Level 3 – Unobservable inputs for the asset or liability, reflecting the Company's own assumptions about the assumptions that market participants would use in pricing the asset or liability.

 Fair Value Measurements on a Recurring Basis

 The fair value for derivative instruments is determined using valuation models that incorporate observable market inputs, such as interest rates and currency exchange rates, and is classified within Level 2 of the fair value hierarchy.

 The fair value of contingent consideration is estimated as of the date of the acquisition and is recorded as part of the purchase price, and is subsequently re-measured to fair value at each reporting date, based on a probability-weighted analysis using a rate that reflects the uncertainty surrounding the expected outcomes, which the Company believes is appropriate and representative of market participant assumptions.

 Fair Value Measurement Disclosure

 The fair value of the Company's short-term debt is estimated using observable market inputs, including current interest rates for similar types of borrowings. The fair value of long-term debt is determined based on quoted prices for identical or similar instruments in active markets. The fair value of the senior notes are based on quoted prices in active markets for the identical liabilities. The fair value of the term loans are based on recent trading activities of comparable market instruments.

 Non-Recurring Fair Value Measurements

 Certain assets and liabilities are measured at fair value on a non-recurring basis. These include assets and liabilities that are measured at fair value in the event of impairment or for disclosure purposes. The discounted cash flow method under the income approach is generally employed to estimate the fair value of the reporting units or identified asset groups. For reporting units, the guideline public company method and the guideline transaction method are also utilized under the market approach. Significant assumptions inherent in estimating fair values include the projected future annual net cash flows for each reporting unit, encompassing net sales, cost of sales, selling, general and administrative expenses, depreciation and amortization, working capital, and capital expenditures. Other critical assumptions involve income tax rates, long-term growth rates, and a discount rate that appropriately reflects the risks inherent in each future cash flow stream.

 Fair Value of Financial Instruments Not Measured at Fair Value

 The carrying amounts of cash and cash equivalents, restricted cash, accounts receivable, accounts payable, and accrued liabilities approximate their fair values due to the short-term nature of these instruments.

 Note 14 — Related Party Transactions
 The Company had a related party receivable with CD&R of $ 5.7 million as of December 31, 2024, representing legal fees paid on their behalf as part of the ongoing stockholder litigation described in Note 15, Commitments and Contingencies. There was no receivable with CD&R for the year ended December 31, 2023.
 The Company had a related party payable of $ 6.0 million to our indirect parent, Camelot Parent, as of December 31, 2024, representing monies paid by Company management for the purchase of incentive units in the Partnership. See Note 11, Share-based Compensation, for further discussion of the incentive units. For the year ended December 31, 2023, this payable was $ 3.0 million.

 Note 15 — Commitments and Contingencies
 As a manufacturer of products primarily for use in building construction, the Company is inherently exposed to various types of contingent claims, both asserted and unasserted, in the ordinary course of business. As a result, from time to time, the Company may become involved in various legal proceedings or other contingent matters arising from claims or potential claims arising out of its operations and businesses that cover a wide range of matters, including, among others, environmental, contract, employment, including applicable benefit and pension plans, intellectual property, securities, personal injury, property damage, product liability, warranty and modification, adjustment or replacement of component parts or units sold, which may include product recalls. The Company insures (or self-insures) against these risks to the extent deemed prudent by its management and to the extent insurance is available. Management believes that the ultimate disposition of these matters will not have a material adverse effect on the Company's results of operations, financial position or cash flows. However, such matters are subject to many uncertainties and outcomes and are not predictable with assurance. The Company believes it is adequately reserved for all matters.
 Environmental
 The Company's operations are subject to various federal, state, local and foreign environmental, health and safety laws. Among other things, these laws regulate the emissions or discharge of contaminants into the environment; govern the use, storage, treatment, disposal and management of hazardous substances and wastes; protect employee health and safety, public health and welfare and the end-users of its products; regulate the chemicals used in its products; and impose liability for the costs of investigating and remediating (as well as other damages resulting from) present and past releases of hazardous substances. Violations of these laws or of any conditions contained in environmental permits could impact the Company's current and future operations.
 The Company believes it is in material compliance with all applicable environmental laws and regulations and has recorded a liability of $ 4.1 million at December 31, 2024 and $ 8.8 million at December 31, 2023.
 Litigation
 The Company is a party to a variety of legal actions arising out of the normal course of business. Plaintiffs occasionally seek punitive or exemplary damages. The Company is also included in other kinds of legal actions, some of which assert or may assert claims or seek to impose fines or penalties and other costs in substantial amounts and are described below.
 Stockholder Litigation
 In July 2022, and pursuant to an Agreement and Plan of Merger dated March 5, 2022, Clayton, Dubilier and Rice, LLC ("CD&R") became the indirect owner of Cornerstone Building Brands. In January 2023, purported former stockholders filed 2 separate complaints challenging the fairness of the Merger. The complaints are captioned Firefighters' Pension System of the City of Kansas City, Missouri Trust and Gary D. Voigt v. Affeldt et al., C.A. No. 2023-0091-JTL (Del. Ch.) and Whitebark Value Partners LP and Robert Garfield v. Clayton Dubilier & Rice, LLC et al., C.A. No. 2023-0092-JTL (Del. Ch.). In both complaints, the plaintiffs allege that CD&R and its affiliates controlled the Company prior to the transaction and that certain directors and officers of the Company, as well as CD&R and its affiliates, breached their fiduciary duties and engaged in conduct resulting in a sale of the Cornerstone Building Brands public stockholders' shares to CD&R at an unfair price. The plaintiffs seek unspecified monetary damages, attorneys' fees, expenses and costs. The court consolidated the two cases, and on May 3, 2023, selected Whitebark Value Partners LP as lead plaintiff. On July 14, 2023, the defendants moved to dismiss the operative complaint. The motion to dismiss was denied on January 10, 2024, and the case is ongoing. On June 26, 2024, the plaintiffs filed an amended complaint. On February 24, 2025, the parties to the case filed a Stipulation of Compromise and Settlement ("Stipulation") setting forth their agreement to settle the litigation. The Stipulation remains subject to court approval. The Stipulation provides for CD&R and the Company, on behalf of the defendants, to pay or cause their respective insurers to pay a total of $ 45.0 million into an escrow account that will be used to pay escrow expenses,

 satisfy any fee and incentive amounts awarded by the court in favor of plaintiff and plaintiff's counsel, and distribute the remaining funds to the non-affiliated shareholders of the Company. The Company's portion of the proposed settlement relating to its indemnification of its former directors and officers is recoverable from insurance. The agreement is contingent upon final court approval, which is anticipated to occur later in 2025.

 In June 2023, a purported former stockholder filed a class action complaint in the United States District Court for the District of Delaware alleging that the Company's disclosures issued in connection with the Merger were materially misleading in violation of Section 14(a) and Section 20(a) of the Securities Exchange Act of 1934. The complaint is captioned Water Island Merger Arbitrage Institutional Commingled Master Fund, L.P. v. Cornerstone Building Brands et al., Case No. 1:23-cv-00701 (D. Del.). The complaint alleges that the Company's directors and officers issued misleading disclosures, which caused stockholders to approve the Merger at an unfair price. The plaintiff seeks unspecified monetary damages, interest, attorney's fees, expenses and costs. On December 8, 2023, the defendants moved to dismiss the operative complaint, and, in the alternative, to stay in litigation. On September 30, 2024, the court granted the defendants' motion to dismiss without prejudice. On October 15, 2024, the plaintiffs filed an amended complaint, which the defendants again moved to dismiss or stay on November 26, 2024. The Company intends to vigorously defend against these claims. The Company cannot predict with any degree of certainty the outcome of this matter or determine the extent of any potential liabilities. The Company also cannot provide an estimate of the possible loss or range of loss.

 Note 16 — Equity Transactions
 In January 2024, the Company paid a dividend on our common stock in the aggregate amount of $ 231.6 million, which was received by our direct parent Camelot Return Intermediate Holdings, LLC, ("Camelot Parent"), and further distributed to Camelot Return Parent, LLC ("Camelot Return Parent"), an indirect parent of the Company. Camelot Return Parent used the funds received to redeem all 1,950,000 preferred units of Camelot Return Parent held by CD&R Pisces Holdings, L.P.

 Note 18 — Reportable Segment and Geographical Information
 Operating segments are defined as components of an enterprise for which discrete financial information is available that is evaluated regularly by the chief operating decision maker ("CODM") for purposes of allocating resources and evaluating financial performance. Our CODM, who is our Chief Executive Officer, reviews financial information presented on a consolidated basis for the purposes of allocating resources and evaluating financial performance. The Company is organized in five operating segments aggregated into three reportable segments: Aperture Solutions (consisting of the Aperture Solutions–U.S. and Aperture Solutions–Canada operating segments), Surface Solutions (consisting of the Surface Solutions–U.S. and Surface Solutions–Canada operating segments) and Shelter Solutions, itself an operating segment. The aggregated reportable segments share similar economic characteristics with respect to product offerings, manufacturing processes, and customer demographics. We operate principally in the U.S. with limited operations in Canada.
 • The Aperture Solutions reportable segment offers a broad line of windows and doors at multiple price-points for residential new construction and repair and remodel end markets in the U.S. and Canada. Its main products include vinyl, aluminum, wood-composite and aluminum clad-wood windows and patio doors, as well as steel, wood-composite, and fiberglass entry doors.
 • The Surface Solutions reportable segment offers a broad suite of surface solutions products and accessories at multiple price-points for the residential new construction and repair and remodel end markets as well as stone

 installation services. Its main products include vinyl siding and accessories, cellular polyvinyl chloride trim, vinyl fencing and railing, stone veneer and gutter protection products.
 • The Shelter Solutions reportable segment designs, engineers, manufactures and distributes extensive lines of metal products for the low-rise commercial construction market under multiple brand names and through a nationwide network of manufacturing plants, distribution centers and retail branches. The Company defines low-rise commercial construction as building applications of up to five stories.
 Management monitors the operations results of its operating segments separately for purposes of making decisions about resources and evaluating performance. Management, including the Company's chief operating decision maker, evaluates performance on the basis of segment earnings before interest, income taxes, depreciation and amortization ("Adjusted reportable segment EBITDA").
 Corporate operating expenses are not allocated to reportable segments. Corporate and Other consists specifically of corporate operating expenses that are generally not allocated to reportable segments, related-party management fees, and other items that are not assigned or allocated to reportable segments. Any intercompany net sales or expenses are eliminated in consolidation.

 Note 19 — Earnings Per Common Share
 Basic earnings per common share is computed by dividing net income allocated to common shares by the weighted average number of common shares outstanding. Diluted income per common share, if applicable, considers the dilutive effect of common stock equivalents. The reconciliation of the numerator and denominator used for the computation of basic and diluted income per common share is as follows:

 Numerator for Basic and Diluted Earnings Per Common Share - Net income (loss) applicable to common shares

 Incentive Plan securities excluded from dilution(1)

 (1)Represents securities not included in the computation of diluted earnings per common share because their effect would have been anti-dilutive.
 The Company calculates earnings per share using the "two-class" method, whereby unvested share-based payment awards that contain non-forfeitable rights to dividends or dividend equivalents are "participating securities" and, therefore, these participating securities are treated as a separate class in computing earnings per share. The calculation of earnings per share presented here excludes the income attributable to unvested restricted stock units related to our Incentive Plan from the numerator and excludes the dilutive impact of those shares from the denominator. Awards subject to the achievement of

 performance conditions or market conditions for which such conditions had been met at the end of any of the periods presented are included in the computation of diluted earnings per common share if their effect was dilutive.
 Earnings per common share is not presented for the Successor period as the Company's common stock is no longer publicly traded either on a stock exchange or in the over-the-counter market.

 Item 9. Changes in and Disagreements with Accountants on Accounting and Financial Disclosure.
 On January 15, 2024, the Audit Committee of the Board of Directors of the Company approved the dismissal of Grant Thornton LLP ("Grant Thornton") as the Company's independent registered public accounting firm effective upon the filing of the Company's Annual Report on Form 10-K for the fiscal year ended December 31, 2023 and approved the selection of Deloitte & Touche LLP ("Deloitte") to serve as the Company's independent registered public accounting firm, for the fiscal year ending December 31, 2024. In connection with our change in accountants, there were no disagreements or reportable events required to be disclosed pursuant to Regulation S-K, Item 304(a)(1)(iv) and Item 304(a)(1)(v).

 Item 9A. Controls and Procedures.
 Evaluation of Disclosure Controls and Procedures
 Our management, under the supervision and participation of our Chief Executive Officer ("CEO") and Chief Financial Officer ("CFO"), evaluated the effectiveness of our disclosure controls and procedures as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (the "Exchange Act"), as of December 31, 2024. Based on the evaluation of our disclosure controls and procedures, our CEO and CFO concluded that, as of December 31, 2024, our disclosure controls and procedures were not effective due to the material weakness in our internal control over financial reporting as described below.
 Notwithstanding the material weakness in our internal control over financial reporting, management has concluded that the audited consolidated financial statements included in this Annual Report on Form 10-K fairly present, in all material respects, our financial position, results of operations and cash flows for the periods presented in conformity with accounting principles generally accepted in the United States of America ("U.S. GAAP").

 Management's Report on Internal Control over Financial Reporting

 Management, including our CEO and CFO, is responsible for establishing and maintaining adequate internal control over financial reporting, as defined in Rule 13a-15(f) and 15d-15(f) promulgated under the Exchange Act and based upon the criteria established in Internal Control-Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission ("the COSO framework"). Internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of our financial statements for external purposes in accordance with U.S. GAAP.
 As permitted by the Securities and Exchange Commission, management excluded from its assessment of internal control over financial reporting as of December 31, 2024, the internal control over financial reporting of Harvey Building Products Corp. ("Harvey") and Mueller Supply Company, Inc. ("Mueller"), which were acquired during April 2024 and July 2024, respectively. The total assets (excluding goodwill and intangible assets) and net sales of both Harvey and Mueller represented 8.6% and 7.6% of our consolidated total assets and consolidated net sales, respectively, at and for the year ended December 31, 2024. See a discussion of these acquisitions in Note 3, Mergers, Acquisitions and Divestitures, to our consolidated financial statements.

 Our management, with the participation of our CEO and CFO, evaluated the effectiveness of our internal control over financial reporting as of December 31, 2024 based on the COSO framework. Based on management's assessment, management has concluded that our internal control over financial reporting was not effective as of December 31, 2024 due to the material weakness described below.

 A material weakness is a deficiency, or combination of deficiencies, in internal control over financial reporting, such that there is a reasonable possibility that a material misstatement of the annual or interim financial statements will not be prevented or detected on a timely basis.

 On April 1, 2024, we implemented an enterprise resource planning ("ERP") system in our Shelter Solutions reportable segment. During the annual period ended December 31, 2024, we identified a material weakness in our internal control over financial reporting that arose from the ineffective application of the software development life cycle ("SDLC") information technology general control. Specifically, the Company determined that the assigned team members lacked the requisite knowledge and experience to develop functional requirements, configure the system, and complete user acceptance tests sufficient to fully test the ERP system prior to going live.

 Changes in Internal Control over Financial Reporting

 Except for the material weakness identified by management and described above, there were no other changes in our internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) during the period ended December 31, 2024, that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

 Management's Plan to Remediate the Material Weakness

 Management has evaluated the deficiency described above and developed a remediation plan designed to strengthen our SDLC processes across the organization, to ensure we have appropriate methodology for additional implementations. The remediation plan requires that: (i) functional business experts are identified, trained, and meet established requirements, (ii) business users have sufficient understanding of the underlying functionality being tested, and (iii) additional levels of review are established throughout the SDLC. The remediation plan is subject to ongoing management review, as well as oversight by the Audit Committee of our Board of Directors.

 Inherent Limitations on Effectiveness of Controls
 Our management, including our CEO and CFO, intends that our disclosure controls and procedures and internal control over financial reporting are designed to provide reasonable assurance of achieving their objectives. However, our management does not expect that our disclosure controls and procedures or our internal control over financial reporting will prevent all errors and all fraud. A control system, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. Further, the design of a control system must reflect the fact that there are resource constraints, and the benefits of controls must be considered relative to their costs. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, have been detected. These inherent limitations include the realities that judgments in decision-making can be faulty, and that breakdowns can occur because of a simple error or mistake. Additionally, controls can be circumvented by the individual acts of some persons, by collusion of two or more people or by management override of the controls. The design of any system of controls also is based in part upon certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions; over time, controls may become inadequate because of changes in conditions, or the degree of compliance with policies or procedures may deteriorate. Because of the inherent limitations in a cost effective control system, misstatements due to error or fraud may occur and not be detected.

 REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
 To the shareholder and the Board of Directors of Cornerstone Building Brands, Inc.
 Opinion on Internal Control over Financial Reporting
 We have audited the internal control over financial reporting of Cornerstone Building Brands, Inc. and subsidiaries (the "Company") as of December 31, 2024, 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, because of the effect of the material weakness identified below on the achievement of the objectives of the control criteria, the Company has not maintained effective internal control over financial reporting as of December 31, 2024, based on criteria established in Internal Control — Integrated Framework (2013) issued by COSO.
 We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB) and in accordance with auditing standards generally accepted in the United States of America, the consolidated financial statements as of and for the year ended December 31, 2024, of the Company and our report dated March 14, 2025, expressed an unqualified opinion on those financial statements.
 As described in Management's Report on Internal Control over Financial Reporting, management excluded from its assessment the internal control over financial reporting at Harvey Building Products Corp. and Mueller Supply Company, Inc., which were acquired during April 2024 and July 2024, respectively, and whose financial statements constitute approximately 8.6% of the Company's consolidated total assets (excluding goodwill and intangibles which were included in management's assessment of internal control over financial reporting as of December 31, 2024) and approximately 7.6% of consolidated net sales as of and for the year ended December 31, 2024. Accordingly, our audit did not include the internal control over financial reporting at Harvey Building Products Corp. and Mueller Supply Company, Inc.
 Basis for Opinion
 The Company's management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management's Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the Company's internal control over financial reporting based on our audit. We are a public accounting firm registered with the 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 audit in accordance with the standards of the PCAOB and in accordance with auditing standards generally accepted in the United States of America. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.
 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 (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) 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 (3) 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.

 Material Weakness
 A material weakness is a deficiency, or a combination of deficiencies, in internal control over financial reporting, such that there is a reasonable possibility that a material misstatement of the company's annual or interim financial statements will not be prevented or detected on a timely basis. The following material weakness has been identified and included in management's assessment: Management has identified a material weakness in internal control over financial reporting due to the ineffective application of the software development life cycle ("SDLC") information technology general control. This material weakness was considered in determining the nature, timing, and extent of audit tests applied in our audit of the consolidated financial statements as of and for the year ended December 31, 2024, of the Company, and this report does not affect our report on such financial statements.

 Audit Committee

 The Audit Committee is responsible for engaging and discharging the independent auditors, as well as monitoring audit functions and procedures. The Audit Committee also provides assistance to the Board regarding its oversight of the Company's financial statements, accounting, risk management and internal control practices. In discharging its duties, the Audit Committee has the authority to retain independent legal, accounting and other advisors and has the sole authority to appoint, retain, replace or terminate the independent auditor.

 The Audit Committee is composed solely of directors who have the requisite financial literacy to serve on the Audit Committee, as determined by our Board.

 Our Board, after reviewing all of the relevant facts, circumstances and attributes, has determined that Mr. Janki, the Chair of our Audit Committee, is an "audit committee financial expert" as defined by Item 407(d)(5)(ii) of Regulation S-K.

 Compensation Committee

 The Compensation Committee is responsible for reviewing and making recommendations to our Board on all matters relating to compensation and benefits provided to executive management. The Compensation Committee also helps oversee the Company's policies and strategies related to talent management and development for executive and senior management. The Compensation Committee is permitted to delegate its authority on all matters for which it is responsible to subcommittees consisting of one or more members.

 The Compensation Committee operates under a Compensation Committee Charter adopted by our Board.

 Nominating and Corporate Governance Committee

 The Nominating and Corporate Governance Committee is responsible for recommending qualified candidates to serve on our Board and evaluating, implementing and overseeing the standards and guidelines for the governance of the Company, including monitoring compliance with those standards and guidelines, as well as overseeing succession planning and evaluating the performance of the Board.

 The Nominating and Corporate Governance Committee operates under a Nominating and Corporate Governance Committee Charter adopted by our Board.

 In identifying and evaluating nominees for director, the Nominating and Corporate Governance Committee first looks at the overall size and structure of our Board to determine the need to add or remove directors and to determine if there are any specific qualities or skills that would complement the existing strengths of our Board, taking into account the overall experience and qualifications of the Board and its committees.

 The Board provides standards for directors in the Board's Corporate Governance Guidelines and Nominating and Corporate Governance Committee Charter. The Corporate Governance Guidelines set forth the requisite skills and characteristics that the Board seeks in Board members, including, but not limited to:

 • High personal and professional ethics, strength of character, integrity, and values;
 • Education, experience, intelligence, independence, fairness, reasoning ability, practical wisdom and vision to exercise sound, mature judgments;
 • Time and effort necessary to learn the Company's business;
 • Breadth of viewpoint and experience necessary for an understanding of the Company's diverse constituencies;
 • Personality, tact, sensitivity, and perspective to participate in deliberations in a constructive and collegial manner;
 • Ability to objectively appraise the performance of management of the Company and in independent mind willing to question management's assumptions when appropriate and;
 • No conflicts of interest that would interfere with the Board members' ability to discharge their duties.

 As part of its periodic self-assessment process, our Board annually reviews the diversity of specific skills and experiences necessary for the optimal functioning of our Board in its oversight of the Company over both the short- and long-term.

 Corporate Governance

 Our Board has adopted Corporate Governance Guidelines to provide guidance on corporate governance matters. These guidelines provide a framework for our corporate governance initiatives and cover topics including, but not limited to, director qualification and responsibilities, Board composition, director compensation and management and succession planning. The Nominating and Corporate Governance Committee is responsible for overseeing and reviewing the guidelines and reporting and recommending to our Board any changes to the guidelines. Our Board is committed to ensuring that the Board is comprised of directors with an appropriate mix of skills, experiences and backgrounds to meet both the Board's current and long-term needs.

 Our Board has adopted a Code of Conduct, which is designed to help officers, directors and employees resolve ethical issues in an increasingly complex business environment. The Code of Conduct is applicable to all of our officers, directors and employees, including our principal executive officer, principal financial officer, principal accounting officer and other persons performing similar functions. The Code of Conduct covers topics, including but not limited to, conflicts of interest, confidentiality of information and compliance with laws and regulations. In 2023, we updated the Code of Conduct to align with the Company's current organizational and operational structure, applicable regulatory requirements and risk profile.

 Our Code of Conduct is available, free of charge, on our website, along with other corporate governance information, at www.cornerstonebuildingbrands.com under the heading "Investors — Sustainability — Governance — Governance Documents."

 Waivers from our Code of Conduct are discouraged, and any waivers from the Code of Conduct that relate to any officer or director must be approved by our Board, and will be disclosed to the fullest extent as required by law and will be posted on our website at www.cornerstonebuildingbrands.com within four business days of any such waiver.

 We have adopted insider trading policies and procedures that govern the purchase, sale and/or other dispositions of our securities by directors, officers, and employees, together with their immediate family members and other persons living in their households. We believe our insider trading policies and procedures are reasonably designed to promote compliance with insider trading laws, rules and regulations. While we have not adopted formal policies and procedures with respect to the Company's transactions in its own securities, it is our policy to comply with all insider trading laws.

 The Board's Role in Risk Oversight

 The Board has ultimate responsibility for risk oversight. Management is responsible for the day-to-day management of the risks we face. The Board and its committees provide active oversight in connection with those efforts of the management, with a particular focus on ensuring that the Company's risk management practices are appropriate and effective. Such risk management practices include, among others, monitoring the risk landscape, and designing or updating policies and controls with respect to operational and legal compliance, cybersecurity, data privacy, climate and succession planning. The Company maintains an enterprise risk management program that includes a multi-factor, qualitative and quantitative process designed to identify and to assess the likelihood, timing and impact of the most critical risks to achieving the Company's strategic objectives. The Board exercises its risk oversight responsibilities through periodic briefing and informational sessions provided by management that cover the significant risks that the Company faces with a focus on how the Company is seeking to manage and mitigate risk. The Audit Committee oversees management's implementation and maintenance of the Company's enterprise-wide risk management process, as well as risks related to, among other things, financial reporting, internal controls, compliance, cybersecurity and data protection. The Compensation Committee oversees risk related to, among other things, the Company's compensation policies and programs. The Nominating and Governance Committee oversees risk related to, among other things, the Company's corporate governance structure, policies and practices, including sustainability and corporate social responsibility matters, the Board's composition, succession planning and the Company's culture.

 Risk Analysis of Our Compensation Plans

 Frederic W. Cook & Co. ("FW Cook") was engaged by the Compensation Committee to assist with the assessment of risk arising from the Company's executive compensation programs and policies. FW Cook's assessment covered each material element of the executive compensation programs, including our compensation mix of (i) fixed components like salary and benefits, (ii) annual incentives that reward overall financial performance, and (iii) multi-year equity awards tied to increases in Company value. Based on these assessments, the Company concluded that our policies and practices do not create risk that is reasonably likely to have a material adverse effect on the Company or to encourage excessive and unnecessary risk taking by executive officers or other employees, because these programs are designed to encourage employees to remain focused on both our short- and long-term operational and financial goals that are drivers of long-term sustained increases in Company value. FW Cook's assessments also took into account that our compensation opportunities are generally measured by a variety of performance metrics, and the program includes a pay mix that is balanced between short- and long-term incentive compensation, including caps on incentive awards and incorporates risk mitigation policies such as clawback policies.

 Sustainability

 During August 2024 we published our Environmental, Social & Governance Report to cover the 2023 calendar year. This report is informed by several reporting frameworks and is in accordance with the 2021 GRI Universal Standards, the Task Force on Climate-Related Financial Disclosure and in partial alignment with the SASB: Building Products & Furnishing Standards. The report documents our progress toward our sustainability objectives and outlines what we aspire to achieve in the future. We recognize our responsibility to increase our positive impact on sustainability issues affecting our environment, our society and the world.

 This belief is embodied in our business strategy, which serves as a guidepost for building our capabilities as a customer-first, solutions-driven company. We aim to focus on the responsible, sustainable solutions our services and products can offer while, in parallel, evaluating our environmental footprint, creating a safe and inclusive work environment for our employees, and improving the communities we serve.

 We are dedicated to constantly improving the sustainability of our solutions through operational efficiencies that reduce our environmental impact while increasing the life cycle and recyclability of our products. We believe recyclable and environmentally favorable products help conserve natural resources and reduce our products' overall environmental impact. We operate lean manufacturing processes to reduce, reuse and recycle waste where possible through both internal initiatives and in partnership with suppliers and other third-party vendors.

 We are mindful of the impacts of global climate change and the contributions to climate change from our manufacturing operations, the transportation and distribution of products, and the end-use of building construction products. In 2024, we analyzed utility provider data (i.e., electricity, natural gas, and water) to assist with energy procurement and analyze our greenhouse gas emissions, and assist with sustainability reporting. Based on this data, we selected specific sites to conduct third-party utility audits to help dictate sustainability initiatives.

 In 2024, we continued our sustainability journey by establishing baselines for key sustainability metrics, implementing a SaaS application to operationalize our sustainability data, and engaging our supply chain with a Supplier Code of Conduct. We continue to engage with our stakeholders to regularly communicate progress, share meaningful sustainability achievements and stories, and outline future sustainability priorities and goals. Our Nominating and Corporate Governance Committee oversees our sustainability efforts, and we believe that our robust governance framework ensures that sustainability is an essential part of our Company's culture and strategy.

 Human Capital Management

 Talent acquisition, engagement and retention are among our highest priorities because our employees design,support and build our exterior building products for our customers. Our core values guide us in creating the environment where we can all win together. This starts with our emphasis on occupational health, safety and employee well-being in our operations, which is one of our core values. To attract and retain the best employees, we focus on providing competitive pay and benefits. We provide benefit programs with the goal of improving the physical, mental and financial wellness of our employees throughout their lifetime. Some examples in the United States (" U.S"). include base and variable pay, medical and dental coverage, paid time off and retirement saving plans with a Company match. We continually review wages to ensure we are fair, equitable, competitive and can attract and retain the best talent. We recruit our talent from a wide range of industries and use many different methods to attract a diverse pool of applicants including community job fairs, job boards, social media, and employee or community agency referrals. We aim to hire and train candidates using a process that is free from biases for or against any individual or group of candidates. We commit to creating a safe and inclusive work environment for our employees. Embracing all employees and applicants, no matter their background, race, age, sexual orientation and identity, and delivering a transparent, fair and engaging experience across the organization are both core to our talent management strategy.

 Cybersecurity and Data Privacy

 Our cybersecurity policy applies to all of our employees, contractors, consultants, third-party service providers and vendors. Our core cybersecurity objectives are related to the overall protection of systems, people, assets, data and security. Our cybersecurity policy contains preventative and detective measures to protect against cyber-attacks that seek to (i) acquire confidential information, (ii) corrupt, damage or destroy information and systems and (iii) flood network resources to render them unavailable. Our employees are required to participate in regular cybersecurity awareness campaigns along with annual cybersecurity, privacy and information training.

 Item 11. Executive Compensation.
 Compensation Discussion and Analysis

 This Compensation Discussion and Analysis ("CD&A") provides information regarding the Company's compensation programs for the named executive officers of the Company (the "NEOs") for year ended December 31, 2024 ("2024"). As such, our NEOs include:

 • Rose Lee, President and Chief Executive Officer, Interim President, Aperture Solutions–U.S.
 • Jeffrey Lee, Executive Vice President, Chief Financial Officer
 • Alena Brenner, Executive Vice President, General Counsel and Corporate Secretary
 • Melissa Jones, President, Surface Solutions–U.S.
 • Matthew Ackley, President, Shelter Solutions
 • Colleen Pritchett, Former President Aperture Solutions–U.S. (1)

 Summary and Highlights for 2024

 Compensation Highlights for 2024

 During 2023 and 2024, our indirect parent, Camelot Return Ultimate, LP, a Delaware limited partnership (the "Partnership" or "Camelot Parent"), granted equity awards to certain key employees considered critical to the success of our Company, including our NEOs, which consisted of interests in future profits of the Partnership. See "Executive Compensation – Long-Term Incentive Awards Granted to NEOs in 2022".

 Performance Highlights in 2024

 Our 2024 financial results were below management's expectations due to several factors, including lower than expected volumes, which have continued into fiscal 2025. We have maintained price discipline across all reportable segments and our work on cost-take-out initiatives, has allowed us to partially offset the impact of lower volumes.

 We remain focused on enhancing long-term growth by taking actions to optimize our portfolio. During 2024, we acquired Harvey Buildings Products Corp. ("Harvey") and Mueller Supply Company, Inc. ("Mueller"), which furthered growth in markets that are core to our operations and strengthened our ability to serve all customers and channels with a comprehensive portfolio of materials, products and brands.

 Executive Compensation Governance

 Compensation Philosophy and Objectives of the Company's Compensation Program

 Our executive compensation philosophy is based on the principle that executive pay should be linked to the performance of the Company. Our Compensation Committee has established the following objectives for our executive compensation programs:

 • Attract, retain and motivate exceptional executives;
 • Reward performance measured against established goals;
 • Provide incentives for future performance; and
 • Align executives' long-term interests with long-term value creation.

 In support of these goals, we designed our compensation programs to reward excellent short-term performance and to encourage executives' commitment to the Company's long-term, strategic business goals. In 2022, the Board of Directors of Camelot Parent (the "Parent Board"), implemented a long-term incentive program consisting of grants of equity from Camelot Parent. This equity is designed to create alignment between our shareholder and Company management by enabling the management team to receive a return based upon the appreciation of the Partnership's equity value that will be created through execution of the long-term strategic plan and profitable growth of the Partnership and its subsidiaries, including the Company.

 Determination and Administration of Compensation Programs and Amounts

 Decisions regarding executive compensation are based primarily on the assessment by the Compensation Committee of each NEO's leadership and operational performance, and potential to enhance long-term value to the Company. Since February 2015, the Compensation Committee has retained a compensation consultant, FW Cook, to assist it in its comprehensive review of the Company's executive compensation program. During 2024, FW Cook continued to advise the Compensation Committee regarding compensation packages for existing executives, new hires, and promotions and other governance related matters (see "Executive Compensation — Compensation of Directors"). The Compensation Committee also relies on its judgment, prior experience, and the judgment of our CEO, Ms. Lee, about each individual NEO in determining the amount and combination of compensation elements and whether each payment or award appropriately encourages and rewards performance. The Compensation Committee meets regularly in separate executive sessions without management personnel present and also requests periodically that our officers or employees attend meetings.

 Based on (i) the benchmarking data prepared by FW Cook, (ii) discussions with and recommendations by Ms. Lee during 2024 and (iii) our pay-for-performance policies, the Compensation Committee determined to maintain our existing executive compensation programs during 2024.

 Role of the Compensation Committee

 Key factors considered by the Compensation Committee in this regard include:

 • Actual performance compared to pre-established financial, operational and strategic goals for the Company;
 • Individual contribution to the Company's financial results, particularly with respect to key measures such as net sales, adjusted EBITDA and working capital as a percentage of net sales;
 • Effectiveness in leading our initiatives to enhance quality and value provided to customers; and
 • Individual commitment and contribution to a culture defined by our core values of safety, integrity and inclusion.

 The Compensation Committee also considered the appropriate balance between incentives for short- and long-term performance as well as internal "pay equity" — in other words, the relative differences in compensation among the executive officers. In addition, our Compensation Committee has reviewed our compensation policies as generally applicable to our employees and believes that our policies do not encourage excessive and unnecessary risk-taking. See "Item 10. Directors, Executive Officers and Corporate Governance –– Risk Analysis of Our Compensation Plans."

 Role of Management

 During 2024, Ms. Lee, Mr. Lee, Ms. Brenner, Mr. Andrich and other senior executives attended certain Compensation Committee meetings at the Compensation Committee's request to advise the Compensation Committee regarding our performance and to recommend compensation and benefits for our NEOs (other than the CEO). Our management, under the leadership of Ms. Lee, plays an important role in establishing and maintaining our compensation programs for our NEOs. Management's role includes recommending plans and programs to the Compensation Committee, implementing the Compensation Committee's decisions regarding the plans and programs and assisting and administering plans in support of the Compensation Committee. The Compensation Committee also relied to a certain extent on Ms. Lee's evaluations of other NEOs whose day-to-day performance was not as visible to the Compensation Committee as it was to Ms. Lee.

 Role of Independent Advisors

 The Compensation Committee's charter provides that it may retain advisors, including compensation consultants, in its sole discretion. The Compensation Committee has assessed the independence of FW Cook pursuant to SEC and NYSE rules and has determined that FW Cook does not have any economic interest or other relationship that would create a conflict with its services to the Compensation Committee.

 Peer Group

 In assessing compensation elements and making compensation decisions for our executive officers, our Compensation Committee considers the executive compensation practices of a peer group of companies of similar size to the Company in related industries. In 2024, our Compensation Committee adopted a revised compensation peer group with the assistance of FW Cook. The changes to the compensation peer group were made to include companies that better align with the Company's operations and business model. The following peer group was used in making compensation decisions for our NEOs during 2024:

 Acuity Brands, Inc.
 Hubbell Inc.
 Masco Corporation

 Allegion plc
 James Hardie Industries plc
 MasterBrand, Inc.

 Carlisle Companies Inc.
 JELD-WEN Holding, Inc.
 Mohawk Industries, Inc.

 Fortune Brands Innovations, Inc.
 Lennox International, Inc.
 Owens Corning

 Generac Holdings Inc.
 Louisiana-Pacific Corporation
 Simpson Manufacturing Co.

 The Company's net sales fall between the median and 75th percentile of the peer companies.

 CEO Compensation

 The Compensation Committee is directly responsible for determining the salary level of the CEO and all awards and grants to the CEO. In September 2021, the Company entered into an employment agreement with our current CEO, Ms. Lee, in connection with her appointment. Ms. Lee's compensation has a strong performance orientation, with annual incentive payouts linked to financial results and Incentive Unit value, as defined in "Long-Term Incentive Awards under the Equity Plan" in this section, driven by Company value creation. Ms. Lee's overall compensation package has also been set at a level that we believe provides appropriate differentiation between CEO compensation and the compensation of other executive officers hired from time to time.

 The principal elements of compensation provided to our NEOs consist of a base salary, the opportunity to earn a bonus under the Company's Bonus Program and long-term incentive compensation under the Camelot Return Ultimate 2022 Equity Incentive Plan ("Equity Plan").

 Base Salary

 The Compensation Committee annually reviews base salaries and makes adjustments in light of competitive data regarding a peer group of companies as well as a NEO's responsibilities, experience and performance levels relative to other executives and the potential for making significant contributions in the future, to ensure that salary levels remain appropriate and competitive. Base salary provides the foundation for calculating other benefits such as annual cash bonus and discretionary matching under the 401(k) plan, so the executive's individual performance has a significant impact on both salary and the benefits derived from salary.

 Annual Bonus

 Short-term annual cash incentive compensation is provided through our annual cash bonus program (the "Bonus Program"), under which annual cash bonuses may be paid to executives to reward their contributions to our business during the year.

 2024 Criteria

 The annual bonus plan is based on the plan measures, which include Pro Forma Company Adjusted EBITDA performance, Business Unit Adjusted EBITDA performance (together, "Pro Forma Adjusted EBITDA"), if applicable, and Pro Forma Company or Business Unit Primary Working Capital as a percentage of net sales.

 EBITDA is defined as earnings before deducting interest expense, income taxes, depreciation, and amortization. Adjusted EBITDA," represents EBITDA further adjusted for the impact of one-time, irregular, or non-recurring charges or income as identified by management. Management believes Adjusted EBITDA is a better measure of the Company's performance than EBITDA or operating income. Refer to Part II, "Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations", under the heading "Non-GAAP Financial Measures" in this report, for a detailed calculation of the Company's Adjusted EBITDA and to Part II, "Item 8. Note 18 — Reportable Segment and Geographical Information" for a detailed calculation of Business Unit Adjusted EBITDA. Pro Forma Adjusted EBITDA also reflects the impact of companies acquired during the year, adjusted for a full year of performance. "Pro Forma Primary Working Capital" consists of net trade accounts receivable, inventories and accounts payable, adjusted on a pro forma basis to include the impact of companies acquired during the year, adjusted for the full year.

 Under the 2024 Bonus Program for Corporate employees including Mses. Lee and Brenner and Mr. Lee, the threshold, target and max of achievement of Pro Forma Company Adjusted EBITDA and Company Pro Forma Primary Working Capital as a

 percentage of net sales metrics is set based on prior Company performance and anticipated market conditions. Under the 2024 Bonus Program for Business Unit executives including Mses. Jones and Pritchett and Mr. Ackley, the threshold of achievement of Pro Forma Company Adjusted EBITDA, Pro Forma Business Unit Adjusted EBITDA and Pro Forma Business Unit Primary Working Capital as a percentage of net sales metrics is based on prior Company performance and anticipated market conditions.

 The payout for threshold levels of achievement, the beginning level at which payouts can be earned, was 50%, and the payout for maximum levels of achievement was 200%. However, payouts for the Pro Forma Primary Working Capital as a percentage of net sales metric were capped at target, 100%, if the Pro Forma Adjusted EBITDA threshold was not met. The Pro Forma Business Unit Adjusted EBITDA must exceed a minimum threshold for Business Unit executives to receive a payout for the Pro Forma Business Units Adjusted EBITDA metric. Our Company believes this plan design keeps employees focused on the most important performance measures and incentivizes achievement of our goals.

 For performance at or above the threshold, potential payments under the Bonus Program were made as follows for corporate executives such as Mses. Lee and Brenner and Mr. Lee:

 Pro Forma Company Primary Working Capital as Percentage of Net Sales

 (1) Surface Solutions–U.S. had a Pro Forma Business Unit Adjusted EBITDA target of $218.6 million, Shelter Solutions had a Pro Forma Business Unit Adjusted EBITDA target of $367.9 million and Aperture Solutions–U.S. had a Pro Forma Business Unit Adjusted EBITDA target of $382.5 million.

 (2) Surface Solutions–U.S. had a Pro Forma Business Unit Primary Working Capital as a percentage of net sales target of 21.1%, Shelter Solutions had a Pro Forma Business Unit Primary Working Capital as a percentage of net sales target of 16.5% and Aperture Solutions–U.S. had a Pro Forma Business Unit Primary Working Capital as a percentage of net sales target of 12.7%.

 Adjusted Company and Business Unit EBITDA and Company and Business Unit Primary Working Capital as a percentage of net sales between these three levels is determined by linear interpolation.

 2024 Bonus Earned

 In 2024, each NEO was assigned a target annual bonus equal to a percentage of his or her base salary, as set forth in the table below. See "Executive Compensation — Narrative to the Summary Compensation Table and Grants of Plan-Based Awards Table — Employment Agreements."

 For corporate executives such as Mses. Lee and Brenner and Mr. Lee during 2024, the Company achieved Pro Forma Company Adjusted EBITDA of $626.1 million against target Company Pro Forma Adjusted EBITDA of $917.9 million and Company Primary Working Capital of 18.2% of net sales against a target working capital of 15.61% of net sales. This achievement level corresponded to a bonus payout at 0.0% of the portion of the target annual bonus based on Company Pro Forma Adjusted EBITDA, and a bonus payout at 0.0% of the portion of the target annual bonus based on Primary Working Capital, resulting in a total payout at 0.0% of target bonus levels. Mses. Jones and Pritchett and Mr. Ackley's bonus also included a measure of business unit performance. Coupled with the Company achievement metrics noted above as part of the

 business unit bonus program, Ms. Jones achieved a total payout of 38.1% of target, Mr. Ackley achieved a payout at 0.0% of target and Ms. Pritchett achieved a total payout at 0.0% of target.

 The Compensation Committee did not revise or reset performance goals during the year, nor did it exercise any discretion to increase or decrease these payout levels, resulting in the bonuses shown in the following table.

 Long-Term Incentive Compensation

 In October 2022, our Parent Board adopted the Equity Plan, under which each of our NEOs received a one-time grant of equity interests that will allow them to receive a return based upon the appreciation of the Partnership's equity value from the date of grant as described below.

 We believe that equity awards to our NEOs must be sufficient in size to provide a strong, long-term performance and retention incentive for executives and to increase their vested interest in the Company and the Partnership. The value of the equity awards granted to NEOs is based on the individual's strategic role in generating long-term value creation for the Company and the Partnership.

 Long-Term Incentive Awards under the Equity Plan

 Our NEOs participate in the Equity Plan. The Equity Plan was adopted to promote the long-term growth and profitability of the Partnership and its subsidiaries, including the Company, by providing those persons who are involved with the growth of the Partnership and its subsidiaries a grant of Class B Profit Units ("Incentive Units") in the Partnership, thereby encouraging such persons to contribute to and participate in the success of the Partnership and its subsidiaries, including the Company. Each Incentive Unit represents a conditional right to receive distributions from Camelot Parent in excess of the "participation threshold" of the Incentive Unit (as set forth in grant documentation). The Parent Board believed the best way to encourage NEOs to contribute and participate in the success of the Partnership and the Company was to provide a grant of Incentive Units to our NEOs with a significant vesting period and, at the same time, provide the opportunity to purchase Class A-2 Profit Units in the Partnership. Therefore, in October 2022, our NEOs were granted Incentive Units and were also offered the opportunity to purchase Class A-2 Profit Units in the Partnership under the Equity Plan.

 At the end of 2024, the Parent Board was comprised of Ms. Lee and Messrs. Donnelly, Krenicki, Sleeper and Young. Ms. Lee did not participate in any discussions with the Parent Board related to the grant of Incentive Units to herself. All grants made under the Equity Plan have been and will in the future be in the form of Class A-2 Profit Units and Class B Profit Units in the Partnership.

 None of the NEOs were granted Incentive Units during 2024.

 Vesting Terms Applicable to Incentive Units

 To incentivize retention, the Incentive Units vest in five equal annual installments over five years, subject, in each case, to the NEO's continued employment or service with the Company through the applicable vesting date. The Incentive Units (both vested and unvested) are subject to forfeiture if the NEO's employment is terminated with cause (as defined in the Equity Plan) or if the NEO fails to comply with confidentiality, non-competition, non-solicitation, non-disparagement, and other restrictive covenants under the Equity Plan, and unvested Incentive Units are subject to forfeiture in the event of the NEO's termination of employment by the Company without cause or upon the NEO's resignation for any reason. The Incentive Units also provide for accelerated vesting of any unvested portion of Incentive Units upon the consummation of a sale of the

 Partnership in certain circumstances or in the case of the NEO's death or disability. See "Executive Compensation – Potential Payments upon Termination or Change in Control – Equity Incentive Awards."

 Retirement Benefits

 Our executive officers, including our NEOs, are eligible to participate in our tax-qualified 401(k) plan. Under the plan, the Company provides matching contributions up to 4% of the NEO's contributions to the plan, subject to a limit of $345,000 per year in 2024.

 In addition, we believe that benefit programs that address the unique circumstances of executives in light of limitations imposed on benefits payable from qualified welfare, profit-sharing and retirement plans are critical in attracting and retaining quality executives. Therefore, we have adopted a Deferred Compensation Plan that allows key employees to elect to defer a portion of their annual salary and annual cash bonus, subject to certain specified maximum deferral amounts. As of December 31, 2024, none of our NEOs elected to participate. See "Compensation — Nonqualified Deferred Compensation."

 Other Compensation

 Employment Agreements, Separation Agreement and Termination Benefits

 The Company has entered into employment agreements with certain NEOs. The descriptions herein pertain to their employment agreements as in effect during 2024. The initial terms of Mses. Lee's and Brenner's and Mr. Lee's employment agreements have expired, and each such agreement has been automatically extended for a period of one year. The employment agreements generally provide for a base salary, target annual bonus and long-term incentive opportunities. In addition, the employment agreements include restrictive covenants, including confidentiality, non-competition, non-solicitation and non-disparagement covenants. See "Executive Compensation – Potential Payments upon Termination or Change in Control – Employee Agreements."

 The employment agreements, Severance Plan, and certain other compensation arrangements of the Company include provisions providing for special payments or benefits upon specified termination events or in connection with the occurrence of a change in control of the Company. However, these arrangements do not include "gross-ups" for golden parachute excise taxes or other taxes. We believe that these termination and change in control benefits provide covered NEOs an incentive to act in the Company's best interest during a change-in-control transaction despite the risk of losing their jobs or a significant change in the nature of their benefits and responsibilities. We also believe that, in some cases, our termination and change in control benefits are necessary to attract and retain certain executives. For a description of the terms of the employment agreements, consulting agreements, Severance Plan and severance agreements and the termination-related provisions of our equity awards, see "Executive Compensation — Potential Payments upon Termination or Change in Control."

 Perquisites and Personal Benefits

 We offer limited perquisites or personal benefits to our NEOs. We provide certain financial planning services and, on occasion, entertainment related expenses (e.g., concert tickets) for certain employees, including some of our NEOs.

 Gross-Ups

 With the exception of limited, one-time tax indemnification in connection with the incurrence of relocation expenses under our relocation policy, the Company generally does not provide for any tax assistance or "gross-ups" for any of its executives.

 Clawback Policy

 The Company has a clawback policy (the "Clawback Policy") to better align our compensation practices with the Company's interests by providing a mechanism to recover cash, stock or other incentive compensation in certain circumstances if a covered employee commits fraud or misconduct, or if the incentive compensation was based on inaccurate financial information resulting from fraud, misconduct or gross negligence.

 Our Clawback Policy allows recovery of all forms of compensation paid to covered employees pursuant to any incentive-based compensation plan, if (i) the Company is required to prepare a material accounting restatement due to noncompliance with any financial reporting requirement under the U.S. securities laws, and such noncompliance is the result of the fraud, misconduct or gross negligence of a covered employee, or (ii) a covered employee has committed fraud or misconduct

 (regardless of whether a restatement occurs). Examples of "misconduct" under the policy include material acts of dishonesty or misrepresentation, acts constituting "cause" under the terms of a covered employee's employment agreement, acts or omissions that could reasonably be expected to cause financial or reputational harm to the Company, and material violations of Company policy.

 The Clawback Policy, which covers all current and former executive officers (including the NEOs), applies to all incentive compensation that is earned or vested after the date the policy was adopted (regardless of when granted). Upon a determination that the Clawback Policy will be applied, the Board may recover, (i) in the case of fraud or misconduct, up to the amount of incentive compensation received in any of the three completed fiscal years prior to the fiscal year in which the Board determines that the executive officer committed conduct giving rise to recoupment under the policy, and (ii) in the case of a material accounting restatement, up to the amount of incentive compensation received in any of the three completed fiscal years ending with (and inclusive of) the fiscal year subject to such restatement. The Board, with input from the Compensation Committee and the Audit Committee, has sole discretion to determine whether and how to apply the Clawback Policy. In determining whether to recover compensation, the Board may take into account any and all factors that it determines to be appropriate and relevant under the circumstances, including the likelihood and costs of recovery, compliance with applicable law, the ability of the executive officer to repay such amount, the tax consequences of the original payment and/or the recoupment to the executive officer (including whether recoupment shall be on a pre-tax or post-tax basis), and any other potentially adverse consequences for the Company or the executive officer arising from seeking enforcement of the policy.

 Compensation Committee Interlocks and Insider Participation

 During 2024, no member of the Compensation Committee served as an executive officer of the Company, and, except as described in "Transactions with Related Persons" below, no such person had any relationship with the Company requiring disclosure herein. During 2024, there were no Compensation Committee interlocks with other companies.

 In 2024, the Company did not grant stock options, stock appreciation rights, or similar instruments and has no policies or practices to disclose pursuant to Item 402(x)(1) of Regulation S-K.

 Compensation Committee Report

 The Compensation Committee has reviewed and discussed the above CD&A with management and, based on such review and discussions, the Compensation Committee recommended to the Board that the CD&A be included in this Annual Report.

Instead, each Incentive Unit has a "hurdle price" or "threshold" associated with the award. Each Incentive Award will entitle the holder to receive distributions only if the aggregate distributions made by Management Holdings in respect of each common unit issued and outstanding on or prior to date of the grant of the incentive unit exceeds the hurdle price or threshold. The figure reflected in this column is the threshold assigned to each Incentive Unit and were set at the time of grant.

 Narrative to the Summary Compensation Table and Grants of Plan-Based Awards Table

 Employment Agreements

 The Company has entered into employment agreements with certain of its NEOs. For a description of the material terms of the employment agreements and for a discussion of enhanced severance benefits upon certain terminations in connection with a change in control of the Company, see "Executive Compensation — Potential Payments Upon Termination or Change in Control — Employment Agreements."

 Long-Term Incentive Awards

 As described above, the Company did not make grants of long-term incentives to our NEOs in 2024. See "Executive Compensation — Compensation Discussion & Analysis — Long-Term Incentive Awards under the Equity Plan."

 (1) On October 7, 2022 and during 2023, certain NEOs received a grant of Incentive Units in the Partnership. The Incentive Units provide the holder with the opportunity to receive, upon certain events, a return based upon the appreciation of the Partnership's equity value from the date of the grant. The Incentive Units do not require the payment of an exercise price, nor do they have an expiration date; however, they only entitle the holder thereof to receive value if and to the extent the underlying security appreciates in value following the grant of the award. Because of this appreciation feature, the Company believes profits interest awards are economically similar to stock options or stock appreciation rights for purposes of the SEC disclosure rules.

 Pension Benefits

 We do not sponsor or maintain any plans that provide for specified retirement payments or benefits, such as tax-qualified defined benefit plans or supplemental executive retirement plans, for our NEOs.

 Nonqualified Deferred Compensation

 Certain employees and non-employee directors of the Company selected by the Compensation Committee are eligible to participate in the Company's nonqualified deferred compensation plan ("DCP"). The DCP is a nonqualified retirement plan created to provide specified benefits to our highly compensated employees and directors. The DCP allows employees to defer up to 80% of their annual salaries and up to 90% of their annual cash bonuses, and allows the Company's non-employee directors to defer up to 100% of their annual retainer fees, until a specified date in the future, including at or after retirement. None of our NEOs participated in the DCP during 2024.

 Potential Payments upon Termination or Change in Control

 We describe below certain payments and benefits that would be received by our NEOs upon specified terminations of their employment, and upon a change in control of the Company, under the employment agreements to which we and our NEOs are parties and under the Severance Plan, as well as under our Incentive Plan and the outstanding equity awards as of the end of 2024. Certain NEOs that do not have employment agreements participate in the Severance Plan, which has similar terms relating to potential payments upon termination or change of control, as described below.

 Employment Agreements and Severance Plan

 Pursuant to terms of an employment agreement with the Company or in the Severance Plan, each of our NEOs is eligible for severance payments and termination benefits upon a future termination of an NEO's employment that is a qualifying termination (i.e., upon termination by the Company without "cause" or by the employee with "good reason"), both prior to and following a change in control of the Company. Severance payments and termination benefits are also payable upon a qualifying termination of an NEO that does not occur during a potential change in control period or within two years following a change in control of the Company.

 Where a qualifying termination occurs, other than during a potential change in control period and other than within two years following a change in control of the Company, each employment agreement or, where applicable, the severance plan, provides (or provided) for (i) payment of one times (two times, in the case of Ms. Lee) the NEO's then-current base salary, payable in equal installments on regular payroll dates over the course of the one-year period (two-year period, in the case of Ms. Lee) immediately following the date of termination, (ii) a prorated annual bonus based on actual performance in the year of termination, (iii) a maximum of twelve months of continued medical and dental coverage (under COBRA at the active-employee rate and at the coverage levels in effect as of the date of termination) in the case of Ms. Lee, a lump sum cash payment equal to eighteen months of the premium cost of family medical and dental coverage at the active-employee rate) and (iv) in the case of Ms. Lee, payment of two times their target annual bonus payable in equal installments over two years (each, a "Qualifying Termination Severance Package").

 In connection with a qualifying termination during a potential change in control period or within two years following a change in control of the Company, the Severance Plan and Mr. Lee's and Ms. Brenner's employment agreements provide for (i) payment of one times the NEO's then-current base salary (payable in equal installments on regular payroll dates over the course of the one-year period under the Severance Plan, or, for Mr. Lee and Ms. Brenner to the maximum extent practicable, in a lump sum), (ii) an additional lump-sum cash severance payment in an amount equal to the sum of (x) one times the NEO's then-current base salary and (y) two times the NEO's target annual bonus for the fiscal year in which the termination occurs, (iii) a pro-rated annual bonus payment based on actual performance in the year of termination and (iv) an additional six months (for a maximum of eighteen months) of continued COBRA coverage.

 In April 2024, we amended the Severance Plan and each of the employment agreements to revise the definition of "change in control." Prior to the amendment, a change in control would occur if: (A) any person becomes the beneficial owner of 25% or more of the combined voting power of Cornerstone Building Brands, (B) as a result of, or in connection with, a tender or exchange offer, merger or other business combination, persons who were directors immediately before the transaction cease to constitute the majority of the Board, (C) the Company is merged or consolidated with another company or transfers substantially all of its assets to another company and, as a result, either (i) less than 50% of the outstanding voting securities of the resulting company are owned in the aggregate by former Cornerstone Building Brands stockholders or (ii) 50% or more of the outstanding voting securities of the resulting company continue to be owned in the aggregate by former Cornerstone Building Brands stockholders but other than in substantially the same relative proportions as immediately prior to the transaction, or (D) a tender or exchange offer is made for 25% or more of the combined voting power of the Company. The April 2024 amendment increased the thresholds in parts (A) and (D) of this definition from 25% to 50%. In connection with this amendment, we implemented a transition period under the Severance Plan and employment agreements, providing

 for an additional three months of base salary if a participant's termination of employment occurs within the first year following the amendment.

 To the extent payments to a NEO under an employment agreement constitute "parachute payments" within the meaning of Section 280G of the Internal Revenue Code, the payments to be received by the NEO may be reduced to the extent a reduction in the payment amount would put the officer in a better after-tax position than he or she would be in if the excise tax under Section 4999 were imposed on such payments.

 Ms. Pritchett's Separation

 In June 2024, Colleen Pritchett, Former President, Aperture Solution–U.S, separated from the Company.

 Ms. Pritchett received the severance benefits pursuant Severance Plan that are payable upon a non-change in control ("CIC") Qualifying Termination (as defined in the Severance Plan). See "Employment Agreements and Severance Plan."

 In connection with her departure, Ms. Pritchett also provided consulting and advisory services through July 25, 2024, and her services during this period were treated as service for purposes of vesting in the value of her dividend awards that vested through July 25, 2024.

 Equity Incentive Awards

 Upon a sale of the Partnership, all outstanding and unvested Incentive Units will become fully vested and participate in proceeds from such sale unless certain conditions specified in the Equity Plan are met, including the replacement of such Incentive Units with alternative awards having substantially equivalent or better terms.

 Termination Payments

 The following table estimates the value of the payments and benefits that each of our NEOs would receive their employment terminated on December 31, 2024 under the circumstances shown and making the following assumptions. The table excludes (i) amounts accrued through the end of 2024 that would be paid in the normal course of continued employment, such as accrued but unpaid salary and (ii) benefits generally available to all of our salaried employees.

 Pay Ratio Disclosure

 Pursuant to Item 402(u) of Regulation S-K and Section 953(b) of the Dodd-Frank Act, presented below is the ratio of the annual total compensation of our CEO, Ms. Lee, compared to the annual total compensation of our median employee (excluding Ms. Lee).

 The ratio presented below is a reasonable estimate calculated in a manner consistent with Item 402(u). The SEC's rules for identifying the median employee and calculating the pay ratio based on that employee's annual total compensation allow companies to adopt a variety of methodologies, to apply certain exclusions, and to make reasonable estimates and assumptions that reflect their employee populations and compensation practices. As a result, the pay ratio reported by other companies may not be comparable to the pay ratio reported below, as other companies have different employee populations and compensation practices and may utilize different methodologies, exclusions, estimates, and assumptions in calculating their own pay ratios.

 In accordance with SEC requirements, we determined that there have been no changes to our employee population or compensation arrangements in 2024 that we believe would significantly affect our pay ratio disclosure.

 We identified our median employee from all full-time and part-time workers who were included as employees on our payroll records as of a determination date of December 31, 2024. The median was identified using base pay, overtime and bonuses. International employees' pay was converted to U.S. dollar equivalents using exchange rates as of the determination date.

 The total compensation earned by Ms. Lee during 2024, as determined under Item 402 of Regulation S-K, was $5,481,479. The total compensation earned during the same period by our median employee, as determined under Item 402 of Regulation S-K, was $52,552. The ratio of Ms. Lee's total compensation to our median employee's total compensation for 2024 is 104:1.

 Director Compensation

 Directors of the Company who are also employees of the Company do not receive additional compensation for their service as directors. Non-employee directors of the Company receive compensation in addition to reimbursement for expenses incurred to attend and/or participate in meetings. In 2024, each non-employee director received an annual retainer fee, and certain non-employee directors receive additional annual retainer fees for their service as committee chairs, as set forth in the following table:

 Role
 Annual Retainer Fee ($)

 All Non-Employee Directors
 110,000

 Audit Committee Chair
 22,500

 Compensation Committee Chair
 17,000

 In addition, in August 2024, each non-employee director received Incentive Units having an aggregate fair market value of $50,255. These Incentive Units will vest on the earlier of (a) July 25, 2025 and (b) the date the relevant director is unable to stand for re-election due to mandatory retirement under our Corporate Governance Guidelines.

 As a result of their affiliation with CD&R, Messrs. Donnelly, Krenicki, Sleeper and Young did not receive any of the compensation offered to other non-employee directors, except for reimbursement of expenses incurred to attend or participate in meetings.

 Our non-employee directors are also eligible to participate in our DCP and may elect to defer a portion of their annual retainer fees, subject to certain specified maximum deferral amounts. None of our directors participated in the DCP during 2024. See "Executive Compensation — Nonqualified Deferred Compensation" for additional details regarding the terms of the DCP.

 (1) Includes amounts earned during 2024 with respect to annual retainer fees and supplemental retainer fees for Committee Chairs.
 (2) Messrs. Donnelly, Krenicki, Sleeper and Young are not eligible to receive this compensation as employees or partners of CD&R.
 (3) The Company believes that, despite the fact that the Incentive Units do not require the payment of an exercise price, they are most similar economically to stock appreciation rights or stock options, and as such, they are properly classified as "options" under the definition provided in Item 402 of Regulation S-K as an instrument with an "option-like feature." The amounts disclosed in this column are computed using acceptable valuation methodologies in accordance with FASB ASC Topic 718 under U.S. GAAP.

 Item 12. Security Ownership of Certain Beneficial Owners and Management and Related Stockholder Matters.
 Security Ownership of Certain Beneficial Owners and Management

 After the closing of the Merger, Camelot Parent became the indirect owner of all the outstanding shares of Company common stock that CD&R did not already own. As a result, all of the issued and outstanding shares of Company common stock is owned by Camelot Parent. None of our officers or directors beneficially own shares of Company common stock.

 Item 13. Certain Relationships and Related Transactions, and Director Independence.
 Director Independence

 At the closing of the Merger, the Company delisted its common stock on the NYSE. As a result, the Company is no longer required to comply with the NYSE's corporate governance requirements, including the requirement that a majority of its Board be comprised of independent directors. Following the Merger and the removal of our common stock from listing on the NYSE, the Company is no longer subject to the independence requirements for its Board or Board committees. If the Company were subject to the listing standards of the NYSE, we believe that each of Ms. Avedon and Messrs. James, Janki and O'Brien could be determined to be "independent" as defined by the listing standards of the NYSE.

 Our Board met five times during 2024. Each of our directors attended 75% or more of the aggregate of the total number of meetings of our Board held during the period in which they were a director and the total number of meetings held by all board committees on which they served during the periods that they served.

 Our non-management directors meet without the presence of management at regularly scheduled executive sessions. These executive sessions typically occur before or after regularly scheduled meetings of our Board. The presiding director of these executive sessions is the Chair of the Board.

 Transactions with Related Persons

 Policies and Procedures

 The Nominating and Corporate Governance Committee has approved and adopted a written statement of policy and procedures with respect to related party transactions. This policy covers the review, approval or ratification of transactions between us and "related parties" (generally, directors, executive officers and their immediate family members, beneficial owners of 5% or more of any class of our securities, and any entity in which any such persons are employed, are principals, partners or hold a similar position or in which they have a beneficial interest of 5% or more). The policy generally requires that any related party transaction be approved by the Nominating and Corporate Governance Committee or its Chair in advance of the consummation or material amendment of the transaction, subject to exceptions. Under the policy, prior to entering into a related party transaction, a related party must make full written disclosure of all of the facts and circumstances relating to the transaction to our Chief Financial Officer or General Counsel, who must assess this information and decide whether it is a related party transaction. If either of the Chief Financial Officer or General Counsel makes this determination, they must submit the transaction to the Nominating and Corporate Governance Committee or to its Chair for approval in advance of the transaction or for ratification on a periodic basis, in each case at the discretion of the Chief Financial Officer or General Counsel.

 Item 14. Principal Accounting Fees and Services.
 Our Independent Registered Public Accounting Firm and Audit Fees

 In January 2024, the Audit Committee approved the appointment of Deloitte & Touche LLP as our independent registered public accountant. Grant Thornton LLP was the auditor in 2023.

 The following is a description of the professional services performed and the fees billed by Deloitte & Touche LLP and Grant Thornton LLP (in thousands):

In addition, the audit fees billed in 2024 included incremental fees for audit procedures that resulted from the Company's acquisitions.
 (2) Fees for audit-related services billed in 2024 consisted of procedures relating to the Company's debt.

 Deloitte & Touche LLP and Grant Thornton LLP did not perform any tax or other services that impaired their independence in 2024 or 2023, respectively.

 Pre-Approval Policies and Procedures for Audit and Non-Audit Services

 The Audit Committee has developed policies and procedures concerning its pre-approval of the performance of audit and non-audit services for us by Deloitte & Touche LLP. These policies and procedures provide that the Audit Committee shall have the sole authority to pre-approve all audit, audit-related and non-audit or tax services (including the fees and terms thereof) to be performed for us by Deloitte & Touche LLP, subject to the de minimis exception for non-audit services described in Section 10A(i)(1)(B) of the Exchange Act that are approved by the Audit Committee before the completion of the audit. In pre-approving all audit services and permitted non-audit services, the Audit Committee or a delegated member must consider whether the provision of such services is compatible with maintaining the independence of Deloitte & Touche LLP and its status as our independent auditors.

 The Audit Committee must specifically preapprove the terms of Deloitte & Touche LLP's annual audit services engagement. The Audit Committee may, pursuant to its pre-approval policy and Section 10(i)(3) of the Exchange Act, delegate to one or more of its members the authority to consider and pre-approve between quarterly meetings of the Audit Committee management proposals for the engagement of Deloitte & Touche LLP to perform audit and non-audit services for annual fees of up to an aggregate of $100,000 (or such greater amount as authorized by the Audit Committee), provided that those pre-approvals are presented to the entire Audit Committee at its next regularly scheduled meeting. Management proposals arising between quarterly Audit Committee meetings are presented for pre-approval to the Chair of the Audit Committee, and in the event of the Chair's unavailability, to another member of the Audit Committee.

 All of the services performed by Deloitte & Touche LLP in 2024 were approved in advance by the Audit Committee pursuant to the foregoing pre-approval policy and procedures. Additionally, during 2024, Deloitte & Touche LLP did not provide any services prohibited by the Sarbanes-Oxley Act of 2002.
