PART I

Unless we state otherwise or the context otherwise requires, in this Annual Report, all references to "Masonite," "we," "us," "our" and the "Company" refer to Masonite International Corporation and its subsidiaries.

Item 1. Business

Our Company

We are a leading global designer, manufacturer, marketer and distributor of interior and exterior doors and door solutions for the residential and non-residential building construction markets' new construction and repair, renovation and remodeling sectors. Masonite was founded in 1925 in Laurel, Mississippi, by William H. Mason, to utilize vastly available quantities of sawmill waste to manufacture a usable product. Since then, we have provided our customers with innovative products and superior service at compelling values.

We believe we hold either the number one or two market position in the seven product categories we target in North America: interior molded residential doors; interior stile and rail residential doors; exterior fiberglass residential doors; exterior steel residential doors; interior architectural wood doors; wood veneers; and door core. To serve our customers, we operate 64 manufacturing and distribution facilities strategically located in seven countries in North America, Europe, South America and Asia.

The Acquisition

On February 8, 2024, we entered into an Arrangement Agreement (the “Arrangement Agreement”) with Owens Corning (“Owens Corning”), a Delaware corporation, and MT Acquisition Co ULC (“Purchaser”), a British Columbia unlimited liability company and a wholly owned subsidiary of Owens Corning. Subject to the terms and conditions of the Arrangement Agreement, Owens Corning, through Purchaser, agreed to acquire the Company for $133.00 per issued and outstanding share of our common stock, no par value (the “Shares”), in an all-cash transaction. Pursuant to the Arrangement Agreement, following implementation of a court-approved plan of arrangement under the Business Corporations Act (British Columbia), the Company will be a wholly owned subsidiary of Owens Corning (the “Acquisition”). As a result of the Acquisition, we will cease to be a publicly traded company. We have agreed to various customary covenants and agreements, including, among others, agreements to conduct our business in the ordinary course during the period between the execution of the Arrangement Agreement and the effective time of the Acquisition (the “Effective Time”). We do not believe these restrictions will prevent us from meeting our debt service obligations, ongoing costs of operations, working capital needs or capital expenditure requirements.

If the Arrangement Agreement is terminated under certain specified circumstances, we or Owens Corning will be required to pay a termination fee. We will be required to pay Owens Corning a termination fee of $75.0 million under specified circumstances, including (a) termination of the Arrangement Agreement in connection with our entry into an agreement with respect to a Superior Proposal (as defined in the Arrangement Agreement) prior to us receiving stockholder approval of the Acquisition, (b) termination by Owens Corning upon an Adverse Recommendation Change (as defined in the Arrangement Agreement), or (c) termination in certain circumstances by either Owens Corning or us upon failure to obtain Masonite Shareholder Approval (as defined in the Arrangement Agreement) or by Owens Corning if we breach our representations, warranties or covenants in a manner that would result in a failure of an applicable closing condition to be satisfied and, if curable, we fail to cure such breach during specific time periods, in each case, if certain other conditions are met. Owens Corning will be required to pay us a reverse termination fee under specified circumstances, including termination of the Arrangement Agreement due to a permanent injunction arising from Competition Laws (as defined in the Arrangement Agreement) when we are not then in material breach of any provision of the Arrangement Agreement and if certain other conditions are met, in an amount equal to $150.0 million. The consummation of the Acquisition remains subject to customary closing conditions, including satisfaction of certain regulatory approvals, approval by our stockholders and other customary closing conditions. The Acquisition is currently expected to close by mid-2024.

For additional information related to the Acquisition, please refer to the preliminary proxy statement to be filed with the SEC and other relevant materials in connection with the transaction that we will file with the SEC and that will contain important information about the Company and the Acquisition.

Our Reportable Segments

The Company has a vertically integrated business model with three reportable segments: North American Residential, Europe and Architectural.

North American Residential. Our North American Residential segment focuses on delivering high-quality interior doors made from wood and recycled wood fibers, durable exterior doors in various designs, materials and sizes and high-quality components to customers primarily in the United States and Canada. With an extensive product portfolio and a well-established presence in the industry, we serve the diverse needs of residential repair, remodel and new construction markets. Residential doors are primarily sold through wholesale and retail distribution channels ensuring that we reach and service a broad spectrum of customers. In the wholesale channel, we sell directly to homebuilders, contractors, lumberyards, dealers and building products retailers in one or two steps. One-step distributors sell doors directly to homebuilders and remodeling contractors, while two-step distributors purchase doors in bulk quantities for serving local door dealers who often perform additional value-added services such as pre-hanging or pre-finishing the door in preparation for installation. The retail channel serves consumers and contractors through retail home centers, both in-store and online. As of the end of 2023, we estimate that the residential repair, renovation and remodeling end market accounted for over half of the net sales for the segment.

Europe. Our European segment offers an extensive portfolio of both recycled wood fiber interior doors and energy-efficient, durable composite exterior doors. Serving customers primarily in the United Kingdom, interior product sales are roughly split between interior and exterior products. Our distribution channels include wholesaler and retail outlets similar to our North American residential strategy, as well as sale of pre-hung interior doors to large housebuilders and sale of pre-finished exterior door systems direct to renovation contractors. Additionally, our Ireland manufacturing facility supplies door facings to Western Europe, contributing to our strong presence and commitment to sustainable building solutions.

Architectural. Our Architectural segment specializes in crafting precision wood interior doors for non-residential building applications. Serving a variety of sectors, including hospitality, healthcare, education and mixed-use facilities, we provide high quality door solutions that comply with diverse needs such as acoustical control, fire rated applications and attack-resistant options. Architectural doors are primarily sold through specialized one-step wholesale distribution channels where distributors sell to general contractors and end-use clients.

In the fiscal year ended December 31, 2023, we sold approximately 26 million doors to approximately 6,600 customers globally. Our fiscal year 2023 net sales by segment and estimated global net sales of doors by end market, geographies and products are set forth below:

Our Strategy

The Doors That Do MoreTM strategy is our plan for achieving sustainable growth and value creation that benefits our stakeholders, and is centered on in three pillars: (1) Drive Product Leadership, (2) Win the Sale and (3) Deliver Reliable Supply.

Drive Product Leadership. Drive Product Leadership emphasizes developing differentiated and innovative door solutions that solve life and living problems. We continually strive to push the boundaries of creativity, employing innovative technology, market insights and customer feedback to design products that enhance the quality of life within the home environment. We strive to provide products and solutions that meet growing homeowner needs for privacy, security, comfort, connectivity, light and style.

Win the Sale. Win the Sale focuses on creating and capturing end-market demand by building our brand through meaningful engagement with homeowners, builders and remodelers and working with our channel partners to identify mutually beneficial growth opportunities. Investing in our channel relationships has always been our priority and our strong partnerships are a primary reason we are a market leader today.

Deliver Reliable Supply. Deliver Reliable Supply is our commitment to be the best supplier in the industry by consistently providing high-quality products and exceptional services for our customers and partners. This pillar is important to supporting our brand and value proposition for our customers, and is achieved by leveraging our large and vertically integrated manufacturing network and our Mvantage operating system.

To enhance our Doors That Do MoreTM strategy, we may pursue targeted acquisitions in adjacent product categories to expand our portfolio of innovative product offerings and unlock the value of fully integrated door systems. In 2023, we acquired EPI Holdings, Inc. (“Endura”) and Fleetwood Aluminum Products, LLC (“Fleetwood”). Endura is a leading innovator and manufacturer of high-performance door frames and door system components including engineered frames, self-adjusting sill systems, weather sealing, multi-point locks and installation accessories used by builders and contractors.

Fleetwood is a leading designer and manufacturer of premium, aluminum-framed glass door and window solutions including multi-slide and pocket glass patio doors, pivot and hinged glass entry doors and folding glass door wall systems for luxury homes.

Our Products

Our focus on consumer-driven innovation led us to think broadly about the entire door system and the value it can bring when integrated. We believe that designing differentiated value-added door systems that solve life and living problems can drive growth in any housing cycle. Recognizing human needs for privacy, security, comfort, connectivity, light and style, we provide an extensive product assortment offering good, better, and best options.

This focus, combined with Masonite’s business relationships in the industry, led to the development of award-winning products such as the M-PwrTM Smart Door and the Masonite Performance Door System. Masonite’s M-PwrTM Smart Doors are the first residential exterior doors to integrate power, light, a video doorbell and a smart lock into the door system. We employ patent-pending, Underwriters Laboratories (“UL”) certified technology to connect residential front doors to a home’s electrical system and wireless internet network. The Masonite Performance Door System features the company’s industry-leading 4-Point Performance Seal, which includes Premium Square Edge Fiberglass Doors, Endura’s Z-Articulating Cap SillTM, PE650 Weatherstripping, Simple Solution® Corner Pads and FrameSaver® rot-proof door frame. The addition of Fleetwood enables us to offer an expansive range of products to the high-end market. Fleetwood’s innovative product lines include the EDGE Collection, the Gen4 Series and the 3-Series. These luxurious, best-in-class doors and windows are complemented by high-quality components and hardware such as the Arche-Duct sub-floor draining system and the patented Archetype Locking and Rolling system.

Components

In addition to residential and non-residential doors, we also sell several crucial door components to the building materials industry. Within the residential door market, we provide sills, frames, astragals, locking systems, molded interior door facings, agri-fiber and particleboard door cores, and wood cut stock components. Within the non-residential door market, we are a supplier of mineral and particleboard door cores and veneer door facings.

Molded door facings are thin sheets of molded hardboard produced by grinding or defibrating wood chips, adding resin and other ingredients to create a thick mat of wood fibers, which is then pressed between steel die plates to form a molded sheet. Surfaces may be smooth or contain a wood grain pattern. Following pressing, molded door facings are trimmed, primed and shipped to door manufacturing plants where they are mounted on frames to produce molded doors.

Door framing materials, commonly called cut stock, are wood or MDF components that constitute the frame on which interior and exterior door facings are attached. Door cores are pressed fiber mats of refined wood chips or agri-fiber used to construct solid core doors. For doors that must achieve a fire rating higher than 45 minutes or longer, the door core typically consists of an inert mineral core or similar compounds.

Interior Doors

Designed for versatility and durability, our molded panel doors are available with either a hollow or solid core. Assembled with two molded door facing panels around a wood or MDF frame, these doors are used in closets, bedrooms, bathrooms and hallways. Our solid core interior doors are crafted to provide more sound dampening material to enhance comfort and privacy within living spaces. Our molded panel product line is subdivided into several distinct product groups: our Classic Molded Panel series is a combination of classic styling and durable construction in a variety

4

of styles preferred by our customers when price sensitivity is a factor in product selection; the West EndTM Collection introduces modern linear designs to the molded panel interior door category; the Heritage® Series features recessed, flat panels and sharp, Shaker-style profiles which integrate into transitional styles found in many homes today; and the Livingston lines features versatile and timeless design for any style of home. Our doors can be upgraded to our environmentally friendly EmeraldTM door construction, which enables homeowners, builders and architects to meet specific product requirements and "green" specifications to attain Leadership in Energy and Environmental Design ("LEED") certification.

Our flush interior doors, available with either a hollow or solid core, are crafted by assembling two plywood facings, MDF, composite wood or hardboard over a wood or MDF frame. Our flush door range offers solutions for every preference, from base residential flush doors made of unfinished composite wood to high-end wood veneer doors.

Exterior Doors

Our exterior doors are made primarily of steel, fiberglass or composite materials. Fiberglass doors, recognized for their premier quality, feature an assembly of two fiberglass facings encompassing a sturdy wood frame. Innovative design, coupled with polyurethane insulation, ensures resilience against varying temperatures and the elements. We introduce light and style into living spaces with our VistaGrande flush-glazed fiberglass doors, seamlessly integrating aesthetics and functionality. Featuring glass inserts, these doors add an elegant touch to any entryway or interior space.

In the United Kingdom, Door-StopTM branded composite doors are manufactured into pre-hung door sets, while our Solidor® exterior doors are assembled around a solid timber core that provides enhanced security. Both product lines offer the benefits of durable materials that require minimal maintenance, and numerous designs and color choices. Innovative consumer marketing has led Solidor® to become one of the United Kingdom's most recognized manufacturers and suppliers of composite doors.

Stile and rail doors are made from wood or MDF with individual panels that have been cut, milled, veneered and assembled from various species of lumber, such as clear pine, knotty pine, oak and cherry. Within our stile and rail line, glass panels can be inserted to create what is commonly referred to as a French door, and we offer several glass designs for use in this purpose. Stile and rail doors are used as entry doors for exterior purposes, often including decorative glass inserts.

Steel doors are exterior doors made by assembling two interlocking, flat or paneled steel facings or by attaching two steel facings to a wood or steel frame and injecting the core with polyurethane insulation. With our functional Utility Steel series, the design-centric High Definition family and the pre-finished Sta-Tru® HD, we offer customers the freedom to select the right combination of design, protection and compliance required for any paint-grade exterior door application. In addition, our product offering is significantly increased through our variety of compatible clear or decorative glass designs.

Architectural Doors

Architectural doors are typically highly specified products designed, constructed and rigorously tested to ensure that regulatory standards, such as fire codes and environmental certifications, such as Forest Stewardship Council are met. These doors are sold into institutional (schools, healthcare and government) and commercial (hotels, offices and retail) end markets that often require doors that provide fire safety, security, acoustic comfort and sustainability. Our architectural portfolio is represented by two series, AspiroTM and CenduraTM, comprised of stile and rail, flush wood veneer and painted and laminate doors. The AspiroTM series offers premium, custom aesthetic with high-performance options in acoustic, fire-rated, lead-lined, attack- and bullet-resistant and sustainability categories. The CenduraTM series balances performance and value and is available with our standard aesthetic options with acoustic and fire-rated options. Our portfolio allows us to provide a wide range of solutions to cover the varied needs of commercial and institutional end markets.

Research and Development

We are a global leader in the innovation and development of complete door solutions and the manufacturing processes involved in making such products. As part of the Doors That Do MoreTM strategy, we increased our investment in research and development with a significant focus on developing new, differentiated products, such as our M-PwrTM Smart Doors and Masonite Performance Door Systems, as well as processes and material improvements to enhance quality. We believe that research and development is a competitive advantage for us, and we intend to

5

capitalize on our leadership in this area. Over the last several years, we have built technical and process competencies at the Masonite Innovation Center, our research and development center in West Chicago, IL, which we believe is the largest facility of its kind in the industry. Our end-user experience, research and development and engineering capabilities enable us to organically curate innovative ideas, methodically validate commercial and technical viability, and use cross-functional teams to launch new product concepts and manufacturing processes. The result of this rigorous approach enables us to launch new, proprietary solutions, enhance the manufacturing efficiency and quality of our products and reduce operational costs.

Intellectual Property

We protect the intellectual property that we develop through, among other things, filing for patents in the United States and various foreign countries. In the United States, we currently have 324 design patents and design patent applications and 249 utility patents and patent applications. We currently have 307 foreign design patents and patent applications and 229 foreign utility patents and patent applications. Our United States utility patents are generally applicable for 20 years from the earliest filing date, our United States design patents for 15 years and our United States registered trademarks and tradenames are generally applicable for 10 years and are renewable. Our foreign patents and trademarks have terms as set by the particular country, although trademarks generally are renewable.

Raw Materials

While Masonite is vertically integrated, we require a regular supply of raw materials, such as wood chips, some cut stock components, various composites, steel, glass, aluminum, paint, stain and primer as well as petroleum-based products such as binders, resins and plastic injection frames to manufacture and assemble our products. In 2023, our materials cost accounted for approximately 49% of the total cost of the finished product, from which more than half of the material supply comes from the United States. Wood chips, logs, resins, binders and other additives utilized in manufacturing interior molded facings, exterior fiberglass door facings and door cores are purchased from global, regional and local suppliers, considering the relative freight cost of these materials. Internal framing components, MDF, cut stock and internal door cores are manufactured internally at our facilities and supplemented by suppliers worldwide. We utilize a network of suppliers based in North America, Europe, South America and Asia to purchase other components, including MDF, plywood and hardboard facings, door jambs and frames, glass frames and inserts, and steel coils for the stamping of steel door facings.

Manufacturing Process

As a vertically integrated door manufacturer, we exercise control over every stage of the production process, from initial design and development to the assembly of finished products. Our components plants supply high-quality door facings, door frames and hardware components such as rails, cores and sills to our manufacturing operations. The interior door assembly facilities combine the components to produce a standard hollow or Masonite solid core door. The exterior door facilities assemble steel or fiberglass doors by injecting insulating foam into the facings produced by the component plants. At our door fabrication facilities, final attributes such as painting and framing are added to the door before packaging the doors for delivery.

Our commitment to operational excellence is deeply embedded in our manufacturing process, designed to ensure a reliable supply of high-quality products and exceptional service. The cornerstone of our operational efficiency

6

is Mvantage, our lean operating system which systematically focuses on eliminating waste and creating operational consistency.

In recent years, our commitment to operational excellence has led us to invest in advanced manufacturing technologies and extend the deployment of the Mvantage operating system across our enterprise. This approach is particularly evident in our European facility in Stoke-on-Trent, where material flow and safety are optimized through advanced manufacturing automation. Similarly, our Fort Mill facility in North America, designed with our best Mvantage practices, incorporates the latest technology to optimize manufacturing.

The Mvantage operating system utilizes a wide array of lean management tools to support three distinct areas: Model Plant Transformation; Process Improvement Teams; and Global Standards and Training. The Model Plant Transformation Process aims to improve factory throughput and efficiency using approaches such as equipment reconfiguration for enhanced safety and material flow, inventory optimization, and the implementation and tracking of sustaining performance metrics. Our dedicated team of Process Improvement experts drives critical initiatives to identify and resolve specific areas of inefficiency, while engaging employees at all levels in Kaizen workshops to embed a culture of continuous improvement into our day-to-day operating rhythm. Our Global Standards and Training processes provide our employees with a comprehensive set of tools and operating standards used in every plant to drive a common look and feel across all Masonite facilities.

Our commitment to training extends beyond traditional Kaizen facilitator training, including Six Sigma training certifying Masonite-trained Green and Black Belts. This structured approach, ingrained in our continuous improvement culture, propels improvements in quality and productivity while maintaining an unwavering focus on reliable customer service.

We focus on making Masonite the brand that customers never substitute, aligning with their needs for style, comfort, safety and convenience. Our curated product portfolio reflects our commitment to meeting needs around the home and positions Masonite for future growth. We recognize the importance of simplifying and streamlining the research and decision-making part of the buyer’s journey. As one of North America’s largest designers, manufacturers and marketers of doors, Masonite is positioned as the go-to source for homeowners researching doors and door options.

Our sales and marketing efforts concentrate on key initiatives designed to build a strong brand preference through creative end-user purchasing experience. This targeted approach is driven by our consumer-centric research that uncovers unmet needs around the home. Our commitment involves dedicating more resources to training sales personnel and influencers, improving the in-store experience and launching a revamped Masonite.com.

The new Masonite.com features, such as the visualizer and back-end content distribution tools, are designed to make the buying process more accessible and consistent. The visualizer allows buyers to digitally render their space with a new Masonite door, instilling confidence in their choice.

As part of our cross-merchandising strategy, we market and sell our products through well-established wholesale, retail and direct distribution channels. In North America, our doors are marketed primarily under the Masonite® brand. Other North American brands include: Premdor®, Masonite Architectural®, Barrington®, Oakcraft®, Sta-Tru® HD, Vistagrande®, Flagstaff®, Hollister®, Sierra®, Fast-Frame®, Safe ’N Sound®, Livingston®, AquaSeal®, Cheyenne®, Riverside®, Fast-Fit®, Megantic®, Lemieux Doors®, Harring Doors®, FyreWerks® and Marshfield-

7

Algoma®, Fleetwood® and EDGE. In Europe, doors are marketed under the Masonite®, Premdor®, Premdor Speed Set®, Door-Stop International®, National Hickman®, Defining Spaces®, Solidor®, Residor® and Nicedor® brands.

Our newly acquired component product lines, such as Z-Articulating Cap Sill®, ADAptive, and Ultimate Astragals,Trilennium®, Simple Solution® Corner Pads and PanoLock® are marketed primarily under the Endura Products® brand. We consider the use of trademarks and trade names to be important in the development of product awareness and for differentiating products from competitors and between customers.

In the residential market, we utilize an "All Products" merchandising strategy, providing our retail and wholesale customers access to our entire product range. Our residential wholesale sales professionals focus on down-channel initiatives to ensure our products are "pulled" through our North American wholesale distribution network.

Our North American architectural customers are serviced by a dedicated sales and marketing team, providing architects, door and hardware distributors, general contractors and project owners with a wide range of product application advice, technical specifications and applicable compliance and regulatory certifications.

Service Innovation

We leverage our marketing, sales and customer service activities to ensure our products are strategically pulled through multiple distribution channels. The back-end content distribution tools enable us to push the newest and most up-to-date content to partner websites, ensuring better access to information and consistent messaging. Our proprietary web-based tools, including Mconnect® in North America and the Solidor® and Door-Stop International websites in Europe, provide our channel customers with direct access to a wide range of information and materials, making it easier for them to sell our products.

In our Architectural business, our cloud-based door configurator, DoorBuilderTM Live, enables customers to select and order the correct door easily and intuitively. Our DoorUniversity training program also helps architects select solutions to meet their project and client goals while earning American Institute of Architects continuing education units.

Customers

During fiscal year 2023, we sold our products worldwide to approximately 6,600 customers. Investing in our channel partners has always been our priority, as we see our strong partnerships as one of the main reasons we are a market leader today. In early 2023, we implemented a new Go-To-Market strategy in North America focused on unlocking additional value for our customers and achieving strategic growth objectives. This collaborative approach allowed us to create a shared vision and set of priorities with our channel partners, develop joint business plans and partner with them to deliver best-in-class execution of everyday sales. By achieving further integration and collaboration with our channel partners, we can unlock additional opportunities to win the sale with our end customers.

Although we have many customers worldwide, our largest customer, The Home Depot, accounted for approximately 20% of our total net sales in fiscal year 2023. Due to the depth and breadth of the relationship with this customer, which operates in multiple North American geographic regions and sells a variety of our products, our management believes that this relationship is likely to continue.

Competition

The door manufacturing industry is highly competitive and includes a number of global and local participants. The primary participants in the North American residential interior door industry are Masonite and JELD-WEN, the only vertically integrated manufacturers of molded door facings. Several smaller competitors in the residential interior door industry include Steves and Sons Inc. and Lynden Door, Inc. who primarily source door facings from third-party suppliers. The primary North American residential exterior door industry participants are Masonite, JELD-WEN, Plastpro, Therma-Tru, Feather River and Steves and Sons Inc. The primary participants in the North American non-residential building construction door industry are Masonite and VT Industries, with the remainder supplied by multiple regional manufacturers. Our primary market in Europe is the United Kingdom which is similarly competitive and includes a number of global and local participants. The primary participants in the United Kingdom are our subsidiary Premdor, JELD-WEN, Vicaima and Distinction Doors. Competition in these markets is primarily based on product quality, design characteristics, brand awareness, serviceability, distribution capabilities and value. We also face competition in the other countries in which we operate.

8

A sizable portion of our net sales are sold to large home centers and retailers. The consolidation of our customers and our reliance on fewer larger customers has increased the competitive pressures as some of our largest customers, such as The Home Depot, perform periodic product line reviews to assess their product offerings and suppliers.

Other Corporate Information

Human Capital Resources

Our Company culture is based upon a strong set of values. Our Cultural Pillars define how we act and interact as individuals and as an organization. They reflect the environment we create where people are empowered, collaborative and focused on doing the right thing for our customers, teammates, shareholders, suppliers and communities in which we work.

Our workforce includes over 10,000 employees and contract personnel in seven different countries. This includes approximately 2,200 unionized employees, approximately 85% of whom are located in North America and with the remainder in various foreign locations. Nine of our North American facilities have individual collective bargaining agreements, which are negotiated locally and the terms of which vary by location.

Our Company’s Purpose: We Help People Walk Through WallsSM is reflected in our talent strategy that is focused on attracting and selecting exceptional talent, helping them develop and grow professionally and providing opportunities to recognize and reward their performance, in order to engage and retain our skilled, diverse and motivated workforce. We focus on the employee experience, removing barriers to inclusion, in an effort to enable our people to realize their full potential and highest performance levels. We aspire to be the employer of choice within the markets we operate and seek to grow and develop the capabilities and skills we need for the future while maintaining a robust pipeline of available talent throughout the organization.

We embrace the diversity of our employees and customers, including their unique backgrounds, experiences and talents. In 2021, we formed a corporate Diversity Council and five regional councils representing Canada, the United States, Chile, Mexico and the United Kingdom/Ireland regions. These councils are comprised of cross-functional individuals and leaders from across their respective regions who represent a broad cross section of demographics and assist in our implementation of diversity initiatives. In 2022, our diversity strategy was further enhanced by establishing affinity groups that provide employees with a place of belonging, support and allyship. At Masonite, everyone is valued and appreciated for their unique contributions to the growth and sustainability of our business. We strive to cultivate a culture that supports and enhances our ability to recruit, develop, engage and retain diverse talent at every level. We monitor engagement, partially through a voluntary turnover metric as our goal is to maintain a highly engaged team, thereby reducing voluntary turnover year over year. During fiscal year 2023, our voluntary employee turnover rate for employees in the United States, Canada and the United Kingdom was approximately 16%, a reduction of approximately 500 bps from 2022. These locations collectively make up approximately 85% of our global workforce. We also track 12-month retention rates, which have improved over time. At the end of 2023, our combined hourly employee retention rate in the United States, Canada and the United Kingdom was over 87% across all locations.

We use various methods to listen to our employees and capture their feedback. These methods include all-employee calls, focus groups, employee and manager forums, town hall meetings and company-wide employee engagement surveys. An external analytics and advisory firm conducts our annual employee engagement survey. In 2023, the employee response rate increased to our highest-ever rate of 91%, with seven facilities having a 100% response rate. Since we initially administered the survey in 2017, our mean results have increased, reaching 3.79 out of 5.00 in 2023.

In support of our Company's purpose, in 2021, we launched a quarterly grant program to provide funding to assist individuals, organizations and causes in the communities where we live and work. Our We Help People Walk Through WallsSM Community Grant Program funds the organizations our employees care about most in their local communities. The program has awarded approximately $300,000 in community grants to 68 different causes.

We believe that safety is as vital to our success as productivity and quality. This is reflected in our goal of Target Zero injuries and our continued effort to create an injury-free workplace. Incidents can be prevented through proper management, employee involvement, standardized operations and equipment and attention to detail. Safety programs and training are provided throughout the company to ensure employees and managers have practical tools to help identify and address both unsafe conditions and at-risk behaviors. In 2023, our total incident rate ("TIR"), or the

9

annual number of injuries per 100 full-time equivalent employees, decreased from 1.86 in 2022 to 1.64 in 2023, representing a 12% improvement in workplace incidents. Excluding the Endura acquisition, TIR decreased to 1.35, representing a 27% improvement. While our total incident rate remains well below the industry average, our ambition is to advance workplace safety by striving toward our goal of zero harm operations or Target Zero.

Environmental and Other Regulatory Matters

Masonite was founded nearly a century ago on sustainability principles by turning waste wood from a local sawmill in central Mississippi into a useful hardboard product. At the heart of our business philosophy is the continuous pursuit of waste reduction and resource conservation. Our operations deeply integrate the Mvantage lean operating system, rooted in the lean principle of waste elimination. This system equips Masonite employees with essential skills, empowering them to identify and eliminate sources of waste, including defects, over-processing and transportation.

Our unwavering commitment to sustainability extends to the proactive management of manufacturing waste. The Mvantage system guides us in actively seeking opportunities to divert waste from landfills by recycling materials back into the production process or repurposing them for beneficial use as byproducts. We comprehensively assess our manufacturing process, spanning supply sourcing to shipping, to identify ways to conserve natural resources and reduce solid waste, wastewater and air emissions. By identifying and eliminating waste, we cultivate a safer, more efficient and more productive operational environment at Masonite.

In 2022, we continued to develop a comprehensive carbon reduction strategy to reduce our Scope 1 and 2 greenhouse gas emissions. This strategy is centered on reducing our reliance on fossil fuels, increasing our renewable energy supply and improving overall operational efficiencies. We established a cross-functional committee to develop our responsible wood sourcing program. Our global sourcing team continues to educate our suppliers on our Wood Sourcing Policy.

We are subject to extensive environmental laws and regulations. The geographic breadth of our facilities subjects us to environmental laws, regulations and guidelines in several jurisdictions, including, among others, the United States, Canada, Mexico, the United Kingdom, Ireland, Chile and Malaysia. Such laws, regulations and guidelines relating to, among other things, the discharge of contaminants into water and air and onto land, the storage and handling of certain regulated materials used in the manufacturing process, waste minimization, the disposal of wastes and the remediation of contaminated sites. Many of our products are also subject to various regulations, such as building and construction codes, product safety regulations, health and safety laws and regulations and mandates related to energy efficiency.

Our efforts to ensure environmental compliance include the review of our operations on an ongoing basis, utilizing in-house staff and, on a selective basis, by specialized environmental consultants. The Environmental, Health and Safety team participates in industry groups to monitor developing regulatory actions and actively develop comments on specific issues. Furthermore, environmental assessments are conducted as part of our due diligence review process for our prospective acquisition targets. Based on recent experience and current projections, environmental protection requirements and liabilities are not expected to have a material effect on our business, capital expenditures, operations or financial position.

In addition to the various environmental laws and regulations, our operations are subject to numerous foreign, federal, state and local laws and regulations, including those relating to the presence of hazardous materials and protection of worker health and safety, consumer protection, trade, labor and employment, tax and others. We believe we comply in all material respects with existing applicable laws and regulations affecting our operations. Environmental laws have changed rapidly in recent years, and we may be subject to more stringent environmental laws in the future. Our operations may result in noncompliance with or liability for remediation under environmental laws. Should such eventualities occur, we would record liabilities for remediation costs when remediation costs are probable and can be reasonably estimated. See Item 1A. Risk Factors: "Changes in environmental and health and safety laws and regulations could negatively impact our operations and financial performance."

Item 1A. Risk Factors

You should carefully consider the following factors in addition to the other information set forth in this Annual Report before investing in our common shares. The risks and uncertainties described below are not the only ones facing us. If any of the following risks actually occur, our business, financial condition, results of operations or cash flows could be adversely affected, and the trading price of our common shares could decline, and you may lose all or part of your investment.

Risks Related to the Acquisition

While the Arrangement Agreement is in effect, we are subject to certain interim covenants.

On February 8, 2024, we entered into the Arrangement Agreement with Owens Corning pursuant to which Owens Corning, through Purchaser, agreed to acquire the Company in an all-cash transaction for $133.00 per share of our issued and outstanding common stock.

The Arrangement Agreement generally requires us to operate our business in the ordinary course, subject to certain exceptions, including as required by applicable law, pending consummation of the Acquisition, and subjects us to customary interim operating covenants that restrict us, without Owens Corning’s approval (such approval not to be unreasonably conditioned, withheld or delayed), from taking certain specified actions until the Acquisition is completed or the Arrangement Agreement is terminated in accordance with its terms. These restrictions could prevent us from pursuing certain business opportunities that may arise prior to the consummation of the Acquisition and may affect our ability to execute our business strategies and attain financial and other goals and may impact our financial condition, results of operations and cash flows.

The announcement and pendency of the Acquisition may result in disruptions to our business, and the Acquisition could divert management's attention, disrupt our relationships with third parties and employees, and result in negative publicity or legal proceedings, any of which could negatively impact our operating results and ongoing business.

In connection with the pending Acquisition, our current and prospective employees may experience uncertainty about their future roles with us following the Acquisition, which may materially adversely affect our ability to attract and retain key personnel and other employees while the Acquisition is pending. Key employees may depart because of issues relating to the uncertainty and difficulty of integration or a desire not to remain with us following the Acquisition, and may depart prior to the consummation of the Acquisition. Accordingly, no assurance can be given that we will be able to attract and retain key employees to the same extent that we have been able to in the past.

The proposed Acquisition could cause disruptions to our business or business relationships with our existing and potential customers, suppliers, vendors, landlords, and other business partners, and this could have an adverse impact on our results of operations. Parties with which we have business relationships may experience uncertainty as to the future of such relationships and may delay or defer certain business decisions, seek alternative relationships with third parties, or seek to negotiate changes or alter their present business relationships with us. Parties with whom we otherwise may have sought to establish business relationships may seek alternative relationships with third parties.

The pursuit of the Acquisition may place a significant burden on management and internal resources, which may have a negative impact on our ongoing business. It may also divert management’s time and attention from the day-to-day operation of our remaining businesses and the execution of our other strategic initiatives. This could adversely affect our financial results. In addition, we have incurred and will continue to incur other significant costs, expenses, and fees for professional services and other transaction costs in connection with the proposed Acquisition, and many of these fees and costs are payable regardless of whether or not the pending Acquisition is consummated.

Any of the foregoing, individually or in combination, could materially and adversely affect our business, our financial condition and our results of operations and prospects.

The Acquisition may not be completed within the expected timeframe, or at all, for a variety of reasons, including the possibility that the Arrangement Agreement is terminated prior to the consummation of the Acquisition, and the failure to complete the Acquisition could adversely affect our business, results of operations, financial condition, and the market price of our common stock.

There can be no assurance that the Acquisition will be completed in the expected timeframe, or at all. The Arrangement Agreement contains a number of customary closing conditions that must be satisfied or waived prior to

12

the completion of the Acquisition, including, among others, (1) the adoption of a resolution approving the Acquisition by at least two-thirds of the votes cast on such resolution by our stockholders entitled to vote thereon and represented in person or by proxy at the applicable special meeting of our stockholders, (2) the issuance of interim and final orders by the Supreme Court of British Columbia approving the Acquisition, (3) the expiration or termination of any applicable waiting period or periods under the Hart-Scott-Rodino Antitrust Improvements Act of 1976 (as amended) and the receipt of certain required regulatory clearances and approvals in other jurisdictions under applicable antitrust and foreign direct investment laws and regulations, including in Canada, Mexico and the United Kingdom, and (4) absence of any law, injunction, order or other judgment prohibiting, rendering illegal or permanently enjoining the consummation of the Acquisition. Each party’s obligation to consummate the Acquisition is also subject to the accuracy of the other party’s representations and warranties contained in the Arrangement Agreement (subject, with specified exceptions, to materiality or “Material Adverse Effect” standards), the other party’s performance of its covenants and agreements in the Arrangement Agreement in all material respects, and in the case of Purchaser’s obligation to consummate the Acquisition, the absence of any “Material Adverse Effect” relating to us.

There can be no assurance that all required approvals will be obtained or that all closing conditions will otherwise be satisfied (or waived, if applicable), and, if all required approvals are obtained and all closing conditions are satisfied (or waived, if applicable), we can provide no assurance as to the terms, conditions and timing of such approvals or that the Acquisition will be completed in a timely manner or at all. Many of the conditions to completion of the Acquisition are not within our or Owens Corning’s control, and we cannot predict when or if these conditions will be satisfied (or waived, as applicable). Even if regulatory approval is obtained, it is possible conditions will be imposed that could result in a material delay in, or the abandonment of, the Acquisition or otherwise have an adverse effect on us.

The Arrangement Agreement contains customary mutual termination rights for us and Owens Corning, which could prevent the consummation of the Acquisition, including if the Acquisition is not completed by February 8, 2025 (subject to automatic extension first to May 8, 2025 then to August 8, 2025 in each case, to the extent the regulatory closing conditions are the only conditions that remain outstanding).

The Arrangement Agreement also contains customary termination rights for the benefit of each party, including if the other party breaches its representations, warranties, or covenants under the Arrangement Agreement in a way that would result in a failure of the other party’s condition to closing being satisfied (subject to certain procedures and cure periods). Additionally, the Arrangement Agreement provides termination rights, if certain conditions are met, including (1) for Owens Corning, if our Board of Directors changes its recommendation in favor of the Acquisition, and (2) for us, if our Board of Directors authorizes entry into a definitive agreement with respect to a Superior Proposal (as defined in the Arrangement Agreement) prior to us receiving stockholder approval of the Acquisition.

If the Acquisition is not completed within the expected timeframe or at all, we may be subject to a number of material risks, including:

•the market price of our common stock may decline to the extent that current market prices reflect a market assumption that the Acquisition will be completed;

•if the Arrangement Agreement is terminated under certain specified circumstances, we or Owens Corning will be required to pay a termination fee, including that we will be required to pay Owens Corning a termination fee of $75.0 million under specified circumstances, and Owens Corning will be required to pay us a reverse termination fee of $150.0 million under specified circumstances;

•some costs related to the Acquisition must be paid whether or not the Acquisition is completed, and we have incurred, and will continue to incur, significant costs, expenses and fees for professional services and other transaction costs in connection with the proposed transaction, as well as the diversion of management and resources towards the Acquisition, for which we will have received little or no benefit if completion of the Acquisition does not occur; and

•we may experience negative publicity and/or reactions from our investors, customers, partners, suppliers, vendors, landlords, other business partners and employees.

Stockholder litigation could prevent or delay the closing of the pending Acquisition or otherwise negatively impact our business, operating results and financial condition.

13

We may incur additional costs in connection with the defense or settlement of stockholder litigation in connection with the pending Acquisition. Such litigation may adversely affect our ability to complete the pending Acquisition. We could incur significant costs in connection with such litigation, including costs associated with the indemnification obligations to our directors and officers. Such litigation may be distracting to management and may require us to incur additional, significant costs. Such litigation could result in the Acquisition being delayed and/or enjoined by a court of competent jurisdiction, which could prevent the Acquisition from becoming effective.

Risks Related to Economic Conditions and Market Factors

We are exposed to global political, economic and other risks that arise from operating a multinational business that could adversely affect our results of operations.

We have operations in the United States, Canada, Europe and, to a lesser extent, other foreign jurisdictions. In fiscal 2023, approximately 79% of our net sales were derived from the United States, 10% from Canada and 8% from the United Kingdom. Managing a global business is complex and subjects the Company to certain risks inherent with doing business internationally that could disrupt our operations. These risks include, but are not limited to, the following:

•difficulties in enforcing contractual obligations and collecting receivables;

•translations into U.S. dollars for financial reporting purposes of the assets and liabilities of our non-U.S. operations conducted in local currencies;

•tax rates in foreign countries and the imposition of withholding requirements on foreign earnings;

•restrictive governmental trade policies, customs, tariffs, import or export and other trade compliance regulations;

•difficulty in staffing and managing widespread operations and the application of foreign labor regulations;

•the impact of geopolitical events, such as the ongoing conflicts in the Middle East and Eastern Europe or political uncertainty related to the upcoming U.S. presidential election;

•required compliance with a variety of foreign laws and regulations; and

•changes in general economic and political conditions affecting countries where we operate.

Volatility and uncertainty in general business, economic conditions or financial markets could adversely impact our business, financial performance, results of operations and cash flow.

Our business has been sensitive to, and our financial performance is substantially dependent on, the general business and economic conditions in the regions and primary end markets in which we operate. The overall demand for our products could decline as a result of a large number of factors outside of our control, including an economic recession, inflation, deflation, fluctuations in interest rates and foreign exchange rates, availability and cost of capital, supply chain constraints, consumer spending rates, energy and labor availability and costs and the effects of governmental fiscal and monetary policies in the regions in which we operate. Any prolonged economic downturn or volatility in the financial markets that is detrimental to the primary end markets in which we operate could have a material adverse impact on our business, financial performance, results of operations and cash flow.

Volatility of the financial and credit markets and its impact to the construction and building product industries and housing markets, could adversely affect our business, financial performance, results of operations and cash flow.

The current macroeconomic conditions of heightened inflation and interest rates have challenged our primary end markets (residential new construction, home repair, renovation and remodeling and non-residential building construction). Challenging economic conditions, either upward or downward, have historically had a direct correlation to the demand for our products and directly impacts our business, financial performance, results of operations and cash flow. Accordingly, the following factors have had and may continue to have a direct impact on our business in the countries and regions in which our products are sold:

•the amount and type of residential and non-residential construction;

•housing sales and home values;

•the age of existing home stock, home vacancy rates and foreclosures;

•non-residential building occupancy rates;

•increases in the cost of raw materials, energy or wages or any shortage in supplies or labor;

•the availability and cost of credit;

•employment rates and consumer confidence; and

14

•demographic factors such as immigration and migration of the population and trends in household formation.

Steep increases in mortgage rates and reduced availability of financing for the purchase of new homes and home repair, renovations and remodeling could have a material adverse effect on our sales and profitability.

Our business primarily relies on new home construction and home repair, renovation and remodeling projects. The ability of consumers to finance these purchases is affected by increases in mortgage rates and reduced access to consumer financing due to the tightening of lending standards by financial institutions. Mortgage rates increased dramatically from March 2022 through the end of 2023 and, if mortgage rates continue to increase or remain at current levels, consumers may delay or exit homeownership or shift to building smaller homes, which requires less of our products. These outcomes could have a material adverse effect on our business, financial condition and results of operations.

Energy and transportation price fluctuations may adversely impact our manufacturing operations and costs.

The cost of producing our products is impacted by the price of energy, including its impact on transportation costs. Energy prices, in particular oil and natural gas, have fluctuated in recent years, and have been further strained by the ongoing war between Russia and Ukraine. Fuel prices rose significantly during extended portions of 2022. While fuels costs appeared to have moderated in 2023, if fuel prices were to rise again for any reason, including fuel supply shortages or unusual price volatility, the resulting higher fuel prices could materially increase our shipping costs, adversely affecting our results of operations. We are highly reliant on the trucking industry for the transportation of our products. The overall profitability of our operations may be negatively impacted by higher transportation costs as freight carriers raise prices to address the continued shortage of drivers and price of fuel. There can be no assurance that we will be able to recoup any past or future increases in the cost of energy and transportation or pass these costs onto our customers.

Risk Related to Industry Conditions

We operate in a highly competitive industry.

The building products industry is highly competitive. Competitive factors we face include price, quality, customer service and on-time and complete deliveries. To the extent any of our competitors become more successful with respect to any of these competitive factors, we could lose customers and our financial condition and results of operations could decline. Some of our competitors may have access to greater financial resources, larger manufacturing capacity and distribution network than we do, which may allow for more operating and financial flexibility to respond to changes within our industry and end markets and product demand by our customers. Also, a substantial increase in the supply of door and door components resulting from increased production capacity by our competitors could lead us to decrease pricing in order to remain competitive, which in turn could adversely impact our ability to pass on future increases in raw material, labor and other costs to our customers and could reduce profit margins, sales and the profitability of our business. Although price is a significant basis of competition in our industry, we also compete on the basis of on-time delivery and our reputation for quality and customer service. If we fail to maintain our current standards for product quality, the scope of our distribution capabilities or our customer relationships, our reputation, financial condition, results of operations and cash flows could be adversely affected.

The loss of any of our significant customers could adversely affect our business.

Our customers consist mainly of wholesalers, retail home centers and contractors. Our top ten customers together accounted for approximately 50% of our net sales in fiscal year 2023, while our largest customer, The Home Depot, accounted for approximately 20% of our net sales during the same period. We expect that a small number of customers will continue to account for a substantial portion of our net sales for the foreseeable future. Customers that have accounted for a significant portion of our net sales in past periods, individually or as a group, may not continue to do so in future periods, or if continued, may not reach or exceed historical net sales levels in any period. For example, many of our largest customers, including The Home Depot, perform periodic line reviews to assess their product offerings, which have, on past occasions, led to loss of business and pricing pressures. In addition, as a result of competitive bidding processes, we may not be able to increase or maintain the margins at which we sell our products to our most significant customers. Moreover, if any of our customers fail to remain competitive in their respective markets or encounters financial or operational problems, our net sales and profitability may decline. We generally do not enter into long-term contracts with our customers, and they generally do not have an obligation to purchase products from us. Therefore, we could lose a significant customer with little or no notice. Alternatively, our customers could expect that

15

we lower the prices of our products should the cost of raw materials decrease, and our failure to do so could cause such customers to seek similar products from our competitors. The loss of, or a significant adverse change in, our relationships with The Home Depot or any other major customer could cause a material decrease in our net sales. The loss of, or a reduction in orders from, any significant customers, losses arising from customer disputes regarding shipments, fees, merchandise condition or related matters or our inability to collect accounts receivable from any major customer, could have a material adverse effect on results of operation and cash flow.

Consolidation of our customers and suppliers could adversely affect our results of operations.

Over the past few years, many of our customers, distributors and suppliers have undergone consolidation due to being acquired by, or acquiring, another company with similar operations. Consolidation of our customers could result in the loss of a customer or a portion of their business, in addition to an increased reliance on certain key customers. Future consolidation of our customers or distributors and their increased purchasing power, could result in our customers seeking more favorable terms, including pricing, which may limit our ability to maintain pricing or raise pricing in the future. The consolidation of our suppliers has resulted in limiting, and may further limit, our sources of supply and impact pricing. Any future consolidation of our customers, distributors or suppliers could impact our margin growth, results of operations and cash flow.

If we are unable to develop new or improved product offerings that respond to industry trends, demands and consumer preferences, our business and results of operations could be materially affected.

Our business is sensitive to consumer and industry trends, demands and preferences. A key element to our continued success is our ability to improve our existing products or innovate and develop new product lines to respond to industry trends, demands and consumer preferences. Our failure to accurately identify and respond to changing consumer trends successfully, could lead to, among other things, rejection of new or existing product lines, increased substitution of our products and price reductions. In addition, we are subject to the risk that new products, proprietary designs and/or changes in manufacturing technologies may reduce demand for or render our products obsolete. In response, we may not be able to manufacture products at prices that would be competitive in the marketplace or have the financial resources to make necessary technology investments, including the use of artificial intelligence (“AI”), or acquire necessary intellectual property rights to develop new products or improve our existing products. Changes to consumer shopping habits and potential trends towards online purchases could also impact our ability to compete as we currently sell our products mainly through our distribution channels.

Risks Related to our Operations

Availability of raw materials, price fluctuations, and supply chain disruptions may adversely affect our profitability, margins and net sales.

Our profitability is affected by the prices and availability of raw materials and finished goods used in the manufacturing of our products. The principal raw materials used to manufacture our products are wood, wood chips, wood composites, cut stock, steel, glass, aluminum, fiberglass, core material, paint, stain and primer as well as petroleum-based products such as binders, resins and frames. These raw materials and finished goods have historically exhibited price and demand cyclicality. The availability of these raw materials and finished goods and our ability to purchase them may be unexpectedly disrupted by factors beyond our control, including world oil prices, changes in supply and demand, weather, general economic or environmental conditions, labor costs, competition, import duties, tariffs, currency exchange rates and, in some cases, government regulation. Disruptions in transportation lines, such as drought affecting traffic through the Panama Canal and geopolitical-based attacks on ships traversing the Suez Canal, have caused global supply chain issues that have and may continue to adversely impact the availability and timing of delivery of our raw materials and those of our suppliers. Significant and rapid increases in the prices of raw materials or finished goods are more difficult to pass through to customers in a short period of time and may negatively impact our short-term profitability, margins and net sales. Alternatively, should the prices of raw materials or finished goods decrease, our customers may seek corollary reductions in the pricing of our products.

In certain instances, we depend on a single or limited number of suppliers for these raw materials and finished goods. We typically do not have long-term contracts with our suppliers. If we are not able to accurately forecast our supply needs, it may be difficult to obtain additional raw materials to respond to shifting or increased demand. Our dependency upon regular deliveries from particular suppliers means that interruptions or stoppages in such deliveries could adversely affect our results of operations until alternative suppliers are arranged, if at all, and under terms and pricing that could be prohibitive. Additionally, qualifying an alternative supplier, even if available, may require a

16

lengthy regulatory approval process to confirm that the substituted raw material meets the regulatory standards required to be used in our products. Moreover, some of our raw materials, especially those that are petroleum- or chemical-based, may require significantly more lead time and procuring a compatible substitute to meet our demand may not be available or of the same quality or price. Even if acceptable alternatives are found, the process of locating and securing such alternatives might be disruptive to our business and our net sales and profitability may decline.

Our business is subject to climate-related risks that could adversely affect our net sales, results of operations and cash flow.

We analyze climate risks in two separate categories: transition risks and physical risks. Physical risk refers to the risks related to the physical impacts of climate change, driven by severe weather conditions, such as unusually prolonged warm or cold conditions, rain, blizzards, wildfires, flooding or hurricanes. An increase in average global temperatures could result in more frequent and severe weather events that may affect our corporate headquarters, our manufacturing plants or plants owned by customers or suppliers. Additionally, weather events could disrupt the supply of inbound raw materials and outbound finished products and could reduce the quality and volume of wood available to our manufacturing plants due to an increase in pest infestation, disease or prolonged drought or flooding. The impact of these types of events on our business may adversely impact our sales, cash flows from operations and results of operations.

Transition risk refers to the transition to a low-carbon economy, which may entail extensive policy, regulatory, legal, technology and market changes. These risks can impact both financial and non-financial risk types and could have broad impacts to our business and operations, such as changes in energy and commodity prices driven by climate-related weather events, prolonged climate-related events that change consumer product preferences and spending, stakeholder perception of our engagement in climate-related policies and new regulatory requirements resulting in higher compliance risk and operational costs.

Our acquisitions could be difficult to integrate and could adversely affect our results of operations.

In the past several years, we have invested a substantial amount of capital in several strategic acquisitions of door and door component manufacturers in North America and the United Kingdom, and we expect that we will continue to do so in the foreseeable future. In January 2023, we completed our acquisition of Endura, which further enhances our product offerings and capabilities of door components. In October 2023, we completed our acquisition of Fleetwood, which expands our portfolio into luxury aluminum-framed doors and windows. As part of our growth strategy, we are continually evaluating possible acquisitions and strategic investments that are complementary to our business and may include expansion into new product lines or businesses. Acquisitions and strategic investments involve numerous risks, including our ability to (a) identify suitable acquisition targets, (b) negotiate acquisitions on acceptable terms and conditions, (c) identify material issues during the due diligence process, and (d) retain key employees, customers and contracts. An acquisition may also entail incurring unanticipated costs in connection with integrating businesses, operating results that are lower than anticipated and the inability to realize the projected value or achieve projected synergies, which could result in an impairment of goodwill, each of which could adversely affect our business, financial condition, results of operations and cash flow.

Integrating an acquired business into our current operations is challenging and may take substantial time, effort and resources by management, and there can be no assurances that any acquisition will be successfully integrated into our operations. Additionally, we may become subject to contingent liabilities or legal claims, including environmental, regulatory or compliance issues, tax liabilities that are not adequately covered by insurance or an enforceable indemnity, and we may be responsible for significant out of pocket expenditures related thereto or otherwise. These liabilities, if they materialize, could have an adverse effect on our business, financial condition, results of operations and cash flow.

We have identified a material weakness in our internal control over financial reporting which could adversely affect our ability to report our results of operations and financial condition accurately and in a timely manner.

Our management is responsible for establishing and maintaining adequate internal control over financial reporting designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with accounting principles generally accepted in the United States of America. As described elsewhere in this Annual Report on Form 10-K, in connection with the audit of our consolidated financial statements for the fiscal year ended December 31, 2023, management identified a material weakness in our internal control over financial reporting. A material weakness is a deficiency, or a combination of

17

deficiencies, in internal control over financial reporting, such that there is a reasonable possibility that a material misstatement of our annual or interim financial statements will not be prevented or detected on a timely basis. The material weakness in our case relates to our internal controls related to accounting for the Company’s business combinations, specific to the sufficiency of evidence supporting management’s review activities (see Part II, Item 9A of this report for further information). Failure to maintain our internal control over financial reporting could adversely impact our ability to report our financial position and results from operations on a timely and accurate basis.

The Company is currently taking actions to remediate this deficiency and believes that the implementation of business combination controls relating to finalizing the preliminary purchase allocations or to new business combinations will substantially remediate the material weakness identified. As we continue to evaluate and take actions to improve our internal control over financial reporting, we may determine to take additional actions to address control deficiencies or determine to modify certain of the remediation measures described above.

Notwithstanding the above, the material weakness did not result in any material misstatements to the consolidated financial statements. Further, management believes and has concluded that the consolidated financial statements included in this report fairly present, in all material respects, the Company's 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.

Increased labor costs, availability of labor, or potential labor disputes and work stoppages at our facilities or the facilities of our suppliers could materially adversely affect our financial performance.

Our financial performance is affected by the availability of qualified personnel and the cost of labor as it impacts our direct labor, overhead, distribution and selling, general and administration costs. We have approximately 10,000 employees and contract personnel worldwide, including approximately 2,200 unionized workers. Employees represented by these unions are subject to collective bargaining agreements that are subject to periodic negotiation and renewal, including our agreements with employees and their respective works councils in the United States, Canada, Mexico and Chile. If we are unable to enter into new, satisfactory labor agreements with our unionized employees upon expiration of their agreements or if our workers were to engage in strikes, a work stoppage or other slowdowns, we could experience substantial disruptions to our operations. Such disruptions could result in late delivery of our products, loss of business and an increase in our operating expenses, which could reduce our net sales and profit margins.

We believe many of our direct and indirect suppliers and customers also have unionized workforces. Strikes, work stoppages or slowdowns experienced by our suppliers and customers could result in slowdowns or closures of facilities where components of our products are manufactured or delivered. Any interruption in the production or delivery of these components could reduce sales, increase costs and have a material adverse effect on our operations.

A disruption in our operations could materially affect our operating results.

We operate facilities worldwide, some of which are located in areas that are vulnerable to hurricanes, earthquakes and other natural disasters. In the event that a hurricane, earthquake, natural disaster, fire or other catastrophic event were to interrupt our operations for any extended period of time, it could delay shipment of merchandise to our customers, damage our reputation or otherwise have a material adverse effect on our financial condition and results of operations. Closure of one of our door facing facilities, which are our most capital intensive and least replaceable production facilities, could have a substantial negative effect on our earnings. We maintain insurance coverage to protect us against losses under our property, casualty and umbrella insurance policies, but that coverage may not be adequate to cover all claims that may arise or we may not be able to maintain adequate insurance coverage in the future at an acceptable cost. Any liability not covered by insurance could materially and adversely impact our financial condition and results of operations.

We may incur rationalization costs and there can be no assurance that our efforts to reduce costs will be successful.

We continually review our manufacturing operations to address market conditions and have reorganized portions of our operations from time to time, particularly following acquisitions or divestitures and periods of economic downturn. We expect to implement continuous improvement initiatives necessary or desirable to improve our business portfolio, address underperforming assets, improve our cost structure and generate additional cash. For example, in December 2022, we approved a restructuring plan intended to (i) better align our operational structure and long-term business strategy and (ii) continue to drive cost efficiencies through an optimized manufacturing footprint. The rationalization of our manufacturing operations and cost savings programs involve substantial planning and may require

18

additional capital investment, consolidation, integration and upgrading of facilities, functions and systems. These actions could result in a decrease in our short-term earnings as a result of restructuring charges and related impairments and other expenses, including severance costs. Additionally, these actions may result in temporary constraints upon our ability to manufacture the quantity of products necessary to fill orders in a timely manner, could affect customer demand for our products and may result in the loss of business and impact our results of operations.

While we expect these initiatives to result in profit opportunities and savings throughout our organization, our estimated profits and savings are based on assumptions that may prove to be inaccurate, and as a result, there can be no assurance that we will realize profits and cost savings or that, if realized, these profits and cost savings will be sustained. Failure to achieve or delays in achieving projected levels of efficiencies and cost savings from such measures, or unanticipated inefficiencies resulting from in-process or contemplated manufacturing and administrative reorganization actions, could adversely affect our business, financial condition, results of operations and cash flows and harm our reputation

We may be the subject of product liability, product warranty and other claims or legal proceedings that could adversely affect our results of operations and financial performance.

We manufacture products that are used in a wide variety of residential and commercial applications. Our failure to maintain our product quality standards could result in product-related claims against us, including class action lawsuits, regulatory penalties and warranty claims in the event our products do not meet the required customer specification or result 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 product defect-related damages or an order to cease production of, recall or redesign such products and potentially subject us to regulatory penalties. Any such claim or lawsuits, whether or not successful, could result in adverse publicity, loss of customers and a decline in sales. We maintain insurance coverage to protect us against product liability claims, but that coverage may not be adequate to cover all claims or costs that may arise or we may not be able to maintain adequate insurance coverage in the future at an acceptable cost. Any liability not covered by insurance or that exceeds our established reserves could materially and adversely impact our financial condition and results of operations.

Our ability to attract, engage and retain talented employees and executives is critical to our success.

Our ability to attract, engage and retain talented and qualified employees at all levels within our organization, including production employees, key managers and executives, is critical to the success of our business. We need an engaged workforce to serve our customers and meet our business objectives. Competitive pressures and a tightened labor market within and outside our industry may make it more difficult and expensive to attract and hire qualified employees. Increased turnover of production employees, the retirement of or unforeseen loss of key employees without appropriate succession planning or the ability to develop or hire replacements with the requisite skill could make it difficult to manage our business, meet our business objectives, and hinder the development or enhancement of products and may result in a material adverse effect on our business, financial condition, results of operations and cash flows.

We rely on the continuous operation of our information technology systems. Failure to upgrade, maintain or prevent damage to such information technology systems or implement contemporary technology systems may adversely affect our business, results of operations and customer relationships.

Our information technology systems allow us to manufacture doors and door components, accurately maintain books and records, record transactions, provide information to management and prepare our consolidated financial statements. We may not have sufficient redundant operations to cover a loss or failure in a timely manner. Our operations depend on our information technology systems, which may be vulnerable to damage from cyber-attacks, hardware failure, fire, power loss, telecommunications failure, impacts of terrorism, natural disasters (including those related to climate change) or other disasters. Any damage to our information technology systems could cause interruptions to our operations that materially adversely affect our ability to meet customers’ requirements, resulting in an adverse impact to our business, financial condition and results of operations. We continue to expand, update and upgrade our information technology systems, networks and other core applications, with a focus on optimizing our information technology systems around the globe to meet our changing business demands and to mitigate the risks of a changing cyber security threat landscape. We may not be able to successfully implement certain updates or upgrades to our information technology systems without experiencing difficulties, which could require significant financial and human resources and impact our ability to efficiently service our customers or create accurate financial statements resulting in an adverse impact to our business, financial condition and results of operations.

19

Potential cyber threats and attacks and compliance with data privacy requirements could disrupt our information systems and cause damage to our business and our reputation.

Our internal information security systems and those of our current and any future partners, acquisitions, contractors and consultants may be vulnerable to damage from cyber-attacks, computer viruses, unauthorized access, natural disasters, terrorism, war and telecommunication and electrical failures. Information security threats, which pose a risk to the security of our information systems and the confidentiality, availability and integrity of our data, are increasing in frequency and sophistication as evidenced by significant ransomware attacks and foreign attacks on prominent computer software systems that has had an impact on a wide variety of companies and industries. We have established policies, processes and multiple layers of defenses designed to help identify and protect against intentional and unintentional misappropriation or corruption of our information systems, including third party vendors' systems. Should damage or unauthorized access to our information systems occur, it could lead to the compromise of confidential information, manipulation and destruction of data and product specifications, production downtimes, disruption in the availability of financial data or misrepresentation of information via digital media. While we have not experienced any material breaches in information security, the occurrence of any of these events to our information systems may have a material adverse effect on our business strategy, financial condition, results of operations and cash flow. Specifically, a cyber security breach of our corporate- or plant-level information systems could compromise the confidentiality, availability and integrity of our Company data, cause interruptions to our Company’s operations and adversely affect our reputation. A cyber security break could result in litigation, regulatory action, financial loss, project delay claims and increased costs and operational consequences. Further, regulators continue to expand data privacy and data security requirements, as well as increased fines for non-compliance of security and data breach obligations, specifically in the European Union and United Kingdom under their separate General Data Protection Regulations, in Canada under the Personal Information Protection and Electronic Documents Act and additional provincial data privacy laws, in the United States under the California Consumer Privacy Act and California Privacy Rights and Enforcement Act and other newly enacted or proposed state data privacy laws. Failure to comply with these current and future data privacy laws, policies, industry standards or legal obligations or any security incident resulting in the unauthorized access to, or acquisition, release or transfer of personal information may result in governmental enforcement actions, litigation (including a private right of action), fines, penalties and statutory damages, as well as adverse publicity that may cause our customers to lose trust in us, which could have a material adverse effect on our business and results of operations.

Risks Related to our Financial Condition

To service our consolidated indebtedness, we will require a significant amount of cash. Our ability to generate cash depends on many factors beyond our control and any failure to meet our debt service obligations could harm our business, financial condition and results of operations.

In 2023, in connection with our acquisitions of Endura and Fleetwood, we significantly increased our outstanding indebtedness by entering into a new five-year $250.0 million delayed-draw term loan facility (the "Term Loan Facility") and an amendment to the ABL Facility to increase the borrowing capacity to $350.0 million. As a result, we expect that our consolidated debt service obligations for 2024 and beyond will increase from prior amounts.

If we do not generate sufficient cash flows from operations to satisfy our consolidated debt service obligations, we may have to undertake alternative financing plans, such as refinancing or restructuring our indebtedness, selling assets, reducing or delaying capital investments or seeking to raise additional capital. Our ability to restructure or refinance our debt will depend on the capital markets and our financial condition at such time. Any refinancing of our debt could be at higher interest rates and may require us to comply with more onerous covenants, which could further restrict our business operations. In addition, the terms of existing or future debt instruments, including the Term Loan Facility, the ABL Facility and the indentures governing the senior notes, may restrict us from adopting some of these alternatives. If we are unable to generate sufficient cash flows to satisfy our debt service obligations, or to refinance our obligations on commercially reasonable terms, it would have an adverse effect, which could be material, on our business, financial condition and results of operations.

Under such circumstances, we may be unable to comply with the provisions of our debt instruments, including the financial covenants in the Term Loan Facility and the ABL. If we are unable to satisfy such covenants or other provisions at any future time, we would need to seek an amendment or waiver of such financial covenants or other provisions. The lenders under the Term Loan Facility, the ABL Facility may not consent to any amendment or waiver requests that we may make in the future, and, if they do consent, they may do so on terms which are unfavorable to us.

20

The lenders will also have the right in these circumstances to terminate any commitments they have to provide further borrowings. If we are unable to obtain any such waiver or amendment, our inability to meet the financial covenants or other provisions of the Term Loan Facility, the ABL Facility would constitute an event of default thereunder, which would permit the lenders to accelerate repayment of borrowings under the Term Loan Facility, the ABL Facility, which in turn would constitute an event of the default under the indenture governing the senior notes, permitting the holders of the senior notes to accelerate payment thereon. Our assets and/or cash flows, and/or that of our subsidiaries, may not be sufficient to fully repay borrowings under our outstanding debt instruments if accelerated upon an event of default, and the secured lenders under the Term Loan Facility, the ABL Facility could proceed against the collateral securing that indebtedness. Such events would have a material adverse effect on our business, financial condition and results of operations, as well as on our ability to satisfy our obligations in respect of the senior notes.

The terms of the Term Loan Facility, the ABL Facility and the indentures governing the senior notes may restrict our current and future operations, particularly our ability to respond to changes in our business or to take certain actions.

The credit agreements governing the Term Loan Facility and the ABL Facility as well as the indentures governing the senior notes contain, and the terms of any future indebtedness of ours likely contain, a number of restrictive covenants that impose significant operating and financial restrictions, including restrictions on our ability to engage in acts that may be in our best long-term interests. The indentures governing the senior notes and the credit agreements governing the Term Loan Facility and ABL Facility include covenants that, among other things, restrict our and our subsidiaries’ ability to:

•incur additional indebtedness and issue disqualified or preferred stock;

•make restricted payments;

•sell assets;

•create restrictions on the ability of their restricted subsidiaries to pay dividends or distributions;

•create or incur liens;

•enter into sale and lease-back transactions;

•merge or consolidate with other entities; and

•enter into transactions with affiliates.

The operating and financial restrictions and covenants in the debt agreements entered into in connection with the Term Loan Facility, the ABL Facility and any future financing agreements may adversely affect our ability to finance future operations or capital needs or to engage in other business activities.

Fluctuating exchange and interest rates could adversely affect our financial results.

Our financial results may be adversely affected by fluctuating exchange rates. Net sales generated outside of the United States were approximately 20% for the year ended December 31, 2023. In addition, a significant percentage of our costs during the same period were not denominated in U.S. dollars. For example, for most of our non-U.S. manufacturing facilities, the prices for a significant portion of our raw materials are quoted in the domestic currency of the country in which the facility is located or in currencies that are not U.S. dollars. We also have substantial assets outside the United States. As a result, the volatility in the price of the U.S. dollar has exposed, and in the future may continue to expose, us to currency exchange risks. For example, we are subject to currency exchange rate risk to the extent that some of our costs will be denominated in currencies other than those in which we earn revenues. Also, since our financial statements are denominated in U.S. dollars, changes in currency exchange rates between the U.S. dollar and other currencies have had, and will continue to have, an impact on many aspects of our financial results. Changes in currency exchange rates for any country in which we operate may require us to raise the prices of our products in that country and may result in the loss of business to our competitors that sell their products at lower prices in that country.

Moreover, as our current indebtedness is denominated in a currency that is different from the currencies in which we derive a portion of our net sales, we are also exposed to currency exchange rate risk with respect to those financial obligations. When the outstanding indebtedness is repaid, we may be subject to taxes on any corresponding foreign currency gain.

Borrowings under our current Term Loan Facility and ABL Facility are incurred at variable rates of interest, which exposes us to interest rate fluctuation risk. As described above, interest rates rose significantly in 2022 into the first half of 2023 and such rates may continue to increase in the future.

We are subject to the credit risk of our customers.

21

We provide credit to our customers in the normal course of business. We generally do not require collateral in extending such credit and failure by our customers to meet their obligations could have a material adverse effect on our business, financial condition, results of operations and cash flows.

Risks Related to Regulatory Changes and Legal Costs

Changes in climate change regulation may have a material effect on our results of operations.

Laws or regulations aimed at addressing climate change, including local building codes, greenhouse gas emissions, laws or regulations impacting energy supply and other laws, regulations or rules may materially impact demand for our products, our cost of doing business or ability to secure critical permits. For example, in December 2022, the European Union reached an agreement to introduce a carbon tax under the European Union Carbon Border Adjustment Mechanism and there are several United States federal carbon tax proposals that would introduce an economy-wide carbon tax. These proposals include a fee on each unit of carbon dioxide released into the atmosphere, making carbon-intensive goods and services more expensive, which then provides a financial incentive to use less of these products or shift to lower-carbon alternatives. Currently, the use of biomass for energy is considered carbon neutral. A carbon tax scheme might not include this assumption and thus tax our biomass emissions at an equal rate as our fossil fuel emissions. These carbon taxes could adversely affect our business, financial condition, results of operations and cash flows.

Concern over global climate change has led to significant federal, state and international regulatory efforts to limit greenhouse gas emissions and increase climate-related reporting and disclosures, which could impose substantial compliance costs. The State of California recently passed the Climate Corporate Data Accountability Act and the Climate-Related Financial Risk Act that will impose broad climate-related disclosure obligations beginning in 2026 on certain companies doing business in California, including us. A similar proposal is under consideration by the SEC. In addition, new laws or future regulations could directly and indirectly affect our customers and suppliers and our business. We cannot predict the effects on our business that may result from global climate change.

Changes in environmental and health and safety laws and regulations could negatively impact our operations and financial performance.

We must comply with extensive laws, rules and regulations in the United States and in each country where we conduct business, regarding environmental matters, including, without limitation, those governing emissions to air, soil, discharge to water, storage, treatment and disposal of waste, release of contaminants or presence of hazardous or toxic substances, remediation of contaminated sites, protection of worker health and safety and corporate social responsibility matters. These laws, rules and regulations, as well as the interpretation and administration of such laws and regulations by governmental agencies, can change and restrict or prohibit the manner in which we conduct our current operations, such as requiring changes to our manufacturing processes or could increase the cost of some or all our operations. Such changes could adversely affect our business, financial condition, results of operations and cash flows.

Compliance with present or future environmental regulations, such as, for example, future regulations imposed on the use or sale of products containing per- and polyfluoroalkyl substances ("PFAS") or formaldehyde or other similar classified hazardous chemicals in the countries where we conduct business could lead to us incurring significant costs to become compliant, which may include changing our manufacturing process or vendors with whom we have established a longstanding relationship or require us to use alternative raw materials to manufacture our products. We have incurred costs relating to environmental compliance in the past, such as, for example, the Maximum Achievable Control Technology Standard and similar future environmental compliance related expenditures may be required to remain compliant with changing environmental requirements. Despite our efforts to comply with environmental requirements, we are at risk of being subject to civil, administrative or criminal enforcement actions, or of incurring costs, fines or penalties. The amount of any resulting liabilities, costs, fines or penalties may be material.

We must also comply with extensive laws, rules and regulations regarding the protection of worker health and safety and corporate social responsibility matters. Changes in such laws, rules and regulations or in their enforcement could significantly increase our costs of operations which could adversely affect our business. Violations of health and safety laws are subject to civil, and, in some cases, criminal sanctions. As a result of these uncertainties, we may incur unexpected interruptions to operations, fines, penalties or other reductions in income which could adversely impact our business, financial condition and results of operations.

22

Tariffs and evolving trade policy between the United States and other countries, including China, and the impact of anti-dumping and countervailing duties on our business and results of operations.

Steps taken by the United States government to apply tariffs on certain products and materials could potentially disrupt our existing supply chains and impose additional costs on our business, including costs with respect to raw materials upon which our business depends. The increased costs may negatively impact our margins as we may not be able to pass on the additional costs by increasing the prices of our products. For example, recent anti-dumping and countervailing duty trade cases that involved wood molding and millwork and most recently, aluminum, have had and could continue to have an adverse effect on our business and results of operations. In order to reduce the impact on our business and results of operations, we have qualified alternate suppliers and are in the process of attempting to qualify additional alternate suppliers in other jurisdictions and continue to evaluate additional alternate suppliers as a result of these duties.

Our international operations subject us to increased risk for potential liability under anti-bribery or anti-fraud legislation, including the United States Foreign Corrupt Practices Act (“FCPA”).

We operate facilities in seven countries and sell our products around the world. As a result of these international operations, we may enter into, from time to time, negotiations and contractual arrangements with parties affiliated with foreign governments and their officials. In connection with these activities, we are subject to the FCPA, the United Kingdom Bribery Act and other anti-bribery laws that prohibit improper payments or offers of payments to foreign governments and their officials and political parties by United States and other business entities for the purpose of obtaining or retaining business, or otherwise receiving discretionary favorable treatment of any kind and requires the maintenance of internal controls to prevent such payments. In particular, we may be held liable for actions taken by our local partners and agents in foreign countries where we operate, even though such parties are not always subject to our control. As part of our Masonite Values Operating Guide, we have established FCPA and other anti-bribery policies and procedures and offer several channels for raising concerns in an effort to comply with applicable United States and international laws and regulations. However, there can be no assurance that our policies and procedures will effectively prevent us from violating these laws and regulations in every transaction in which we may engage. Any determination that we have violated the FCPA or other anti-bribery laws (whether directly or through acts of others, intentionally or through inadvertence) could result in sanctions that could have a material adverse effect on our results of operations and financial condition.

Changes in government legislation or regulation have a material effect on our results of operations and financial performance.

Many of our products are regulated by federal and state building codes and require specific fire, penetration or wind resistance characteristics. In addition, some of our products must meet certain requirements set by the Environmental Protection Agency (the "EPA") to obtain the energy-efficient "ENERGY STAR" certification. A change in the building codes or energy efficiency requirements established by the EPA or related state laws, or our failure to comply with these requirements, could have a material impact on the manufacturing cost for these products and negatively affect our net sales and results of operations.

In addition, changing laws, regulations and standards relating to corporate governance and public disclosure, including the Sarbanes-Oxley Act, the Dodd-Frank Act and related regulations implemented by the SEC, and the stock exchanges are creating uncertainty for public companies, increasing legal and financial compliance costs and making some activities more time-consuming. Further, new regulations or interpretations of existing laws may result in enhanced disclosure obligations, including with respect to climate change or other Environmental, Social and Governance matters, which could negatively affect us or materially increase our regulatory burden.

We intend to invest in technologies and resources to comply with evolving laws, regulations and standards, and this investment may result in increased general and administrative expenses and a diversion of management’s time and attention from revenue-generating activities to compliance activities. If our efforts to comply with new laws, regulations and standards differ from the activities intended by regulatory or governing bodies due to ambiguities related to practice, regulatory authorities may initiate legal proceedings against us and our business may be harmed.

We may be unable to protect our intellectual property, and we may face claims of intellectual property infringement.

We rely on a combination of United States, Canadian and, to a lesser extent, European patent, trademark, copyright and trade secret laws as well as licenses, nondisclosure, confidentiality agreements and other contractual

23

restrictions to protect our intellectual property portfolio. We maintain a large portfolio of registered trademarks, copyrights and patents. We have selectively pursued protection of our intellectual property, and in some instances, we may not have registered for trademarks or applied for important patents in certain countries. Our patent and trademark applications may not be allowed by the applicable governmental authorities to issue as patents or register as trademarks at all, or in a form that will be advantageous to us. Furthermore, the laws of foreign countries may not protect our intellectual property rights to the same extent as the laws of the United States. Additionally, the processes by which we clear our intellectual property or obtain "freedom to operate" opinions could fail. The failure to obtain worldwide patent and trademark protection may result in other companies copying and marketing products based upon our technologies or under our brand or tradenames outside the jurisdictions in which we are protected. This could impede our growth in existing regions and into new regions, create confusion among consumers and result in a greater supply of similar products that could erode prices for our protected products.

Our ability to protect our intellectual property, including our patents, trademarks, copyrights, trade secrets and licensed intellectual property, from unauthorized use by others is critical to our success. There is no guarantee that the patents and trademarks we have obtained, or other protections such as trade secrets, copyrights and confidentiality agreements with our employees and third parties, will be adequate to prevent imitation of our products by others. Our ability to compete based on our advantageous intellectual property may be harmed if we are unable to protect our products through enforcing or prosecuting our intellectual property rights. These measures may not be adequate to protect our intellectual property from unauthorized disclosure, third-party infringement or misappropriation and is further complicated by recent enacted state laws limiting or banning the use of employee non-competes by employers, as well as proposed rulemaking at the federal level to ban such agreements. If we fail to protect our intellectual property from unauthorized use, we risk the loss of these rights and any associated competitive advantage.

Moreover, we may be accused of misappropriating or infringing on third-party intellectual property. Our trademarks and branding practices could also be challenged. In the event of a challenge, we may be required to defend the Company in litigation, or we may be required to institute litigation to enforce such intellectual property rights from unauthorized use by others. Regardless of the outcome, the enforcement or defense of such rights could result in substantial costs and diversion of resources, and could negatively affect our competitive position, sales, profitability and reputation. Further, if we are found to have infringed on a patent in litigation, we may be liable for monetary damages as well as injunctive relief, which would prevent us from selling the infringing product unless we obtain a license or are able to redesign our product to avoid infringement. Such a license may not be available at all or on terms acceptable to us, and we may not be able to redesign our products to avoid infringement, which could adversely affect our operations.

Our intellectual property rights may be subject to various attacks claiming such rights are valid or unenforceable. These attacks might invalidate, render unenforceable or otherwise limit the scope of the protection that our patents and trademarks afford. In the event we lose the use of a product name, our efforts building such brand would be lost and we would have to devote management resources to rebuilding a brand for such product, which we may do to varying degrees of success. Even if we do prevail in a patent infringement litigation, third parties may still be able to design around our patents, which could harm our competitive position.

If we are unable to replace our expiring patents or fail to continue to innovate, our ability to compete both domestically and internationally will be harmed. In addition, our products face the risk of obsolescence, which, if materialized, could have a material adverse effect on our business.

Our continued success depends on our ability to develop and introduce new or improved products, to improve our manufacturing and product service processes and to protect our rights to the technologies used in our products. If we fail to do so, or if existing or future competitors achieve greater success than we do in these areas, our results of operations and our profitability may decline.

We depend on our door and door component manufacturing intellectual property and products to generate revenue. Some of our patents will begin to expire in the next several years. While we will continue to work to add to our patent portfolio to protect the intellectual property of our products, we believe it is possible that new competitors will emerge in door and door component manufacturing. We do not know whether we will be able to develop additional proprietary designs, processes or products. If any protection we obtain is reduced or eliminated, others could use our intellectual property without compensating us, resulting in financial harm to our business. Moreover, as our patents expire, competitors may utilize the information found in such patents to commercialize their own products. While we seek to offset the losses relating to important expiring patents by securing additional patents on commercially desirable

24

improvements, and new products, designs and processes, there can be no assurance that we will be successful in securing such additional patents, or that such additional patents will adequately offset the effect of the expiring patents.

Further, we face the risk that third parties will succeed in developing or marketing products that would render our products obsolete or noncompetitive. New, less expensive methods could be developed that replace or reduce the demand for our products or may cause our customers to delay or defer purchasing our products. Accordingly, our success depends in part upon our ability to respond quickly to market changes through the development and introduction of new products. The relative speed with which we can develop products, complete regulatory clearance or approval processes and supply commercial quantities of the products to the market are important to remain competitive. Any delays could result in a loss of market acceptance and market share. We cannot provide assurances that our new product development efforts will result in any commercially successful products.

Item 1B. Unresolved Staff Comments

None.

Item 1C. Cybersecurity

As required by Item 106 of Regulation S-K, the following sets forth certain information regarding our cybersecurity governance, strategy and risk management.

Cybersecurity Governance

Our Board of Directors has ultimate oversight of the Company’s privacy and cybersecurity programs and strategy, with each of the Board of Directors' Sustainability and Governance Committee and Audit Committee maintaining oversight responsibility for different elements of these programs. The Sustainability and Governance Committee and Audit Committee inform the full Board of Directors of any cybersecurity learnings or risks that were discussed at the committee level.

The Sustainability and Governance Committee oversees the Company’s strategies and processes related to information security and technology risks, including cybersecurity. The Company’s Chief Information Security Officer (“CISO”), and the Company’s Chief Information Officer present a quarterly cybersecurity report to the Sustainability and Governance Committee and, at times, to the full Board of Directors. The reports include detailed updates on the Company’s cybersecurity risks and threats, the status of projects to strengthen the Company’s information security systems, internal and third-party assessments of the Company’s cybersecurity program maturity against the National Institute of Standards and Technology (“NIST”) Cybersecurity Framework, incident preparedness and the current cybersecurity environment, including current trends or recent noteworthy incidents affecting other companies. The Company has created a cybersecurity incident response plan that requires management, including the Company’s CISO, to take certain mitigating actions including notification to the Company’s Disclosure Committee, upon the occurrence of certain types of incidents that may be material or pose significant risk to the Company, for management. The incident response plan also contains procedures requiring, upon the determination by management that the cybersecurity incident is material, notification to the Board of Directors’ Sustainability and Governance Committee and Audit Committee.

To assist the Company in assessing, preventing, identifying, mitigating and responding to material risks resulting from cybersecurity threats, the Company has developed a comprehensive cybersecurity risk management program led by our CISO. Our CISO is a Certified Information Systems Security Professional by the International Information System Security Certification Consortium who joined the Company in March 2018 after spending 15 years with other organizations as a cybersecurity and information technology (“IT”) professional. Our CISO leads our management-level IT Risk Management Committee composed of IT functional leaders that meet quarterly to review the trending cybersecurity environment, risks and threats to the Company, the progress of cybersecurity mitigation and remediation projects and overall progress against the Company’s cybersecurity strategy. The Company’s senior IT leadership shares progress, findings or concerns reported by the IT Risk Management Committee with senior management to assess the impact of cybersecurity risks and threats to the Company, to assist with driving overall operational awareness, ownership and alignment broadly across the Company for a more effective cybersecurity risk management program.

Cybersecurity Strategy and Risk Management

25

The Company’s enterprise-wide cybersecurity strategy is advanced and reinforced by policies, processes, procedures, standards, technologies and training designed to protect the Company’s IT systems, operations and sensitive business data. The Company has deployed a multiple-layer defensive model, which includes a variety of detective and protective technologies and measures to monitor and protect our critical IT systems, which include among others, intrusion detection and protection, email security, endpoint security, 24/7 third party security monitoring and proactive security testing.

The Company evaluates new and existing third-party service providers and suppliers through a risk assessment that includes interviews and questionnaires to assess their cybersecurity capabilities, process maturity, compliance attestations and the overall technology relationship risk. Each third-party risk assessment is conducted during the contract negotiation process, during certain contract milestones and at other periodic intervals. The final risk assessments and reports are shared with internal teams and IT leadership to assist with ongoing risk mitigation actions. The Company’s cybersecurity defense strategy is regularly tested through internal and third-party penetration testing. Additionally, the Company’s cybersecurity program maturity and risk profile is regularly analyzed and measured internally against generally accepted industry standards and frameworks, including the NIST Cyber Security Framework, the FAIR model and external third-party maturity assessments.

To strengthen the Company’s cybersecurity readiness, the Company has developed a cybersecurity incident response policy and a cybersecurity incident response plan in partnership with various internal department functions and third-party IT consultants. Our cybersecurity incident response plan is based on the NIST incident response lifecycle and co-led by our CISO and director of information security. Our cybersecurity incident response plan has a designated incident response team composed of management members from select departments who each play a role within the four phases of the plan that include preparation, detection analysis, containment, eradication, recovery and post-incident activity. Each phase provides a detailed list of actions and responsibilities for each department to assist in responding to a cybersecurity incident. In the event of a cybersecurity incident, as provided in our cybersecurity incident response plan, a root-cause analysis will be conducted and based on the findings, certain new or improved processes and procedures may be implemented to continually improve the security of our IT systems and confidential data. Additionally, the Company’s incident response team conducts an annual table-top exercise, utilizing the cybersecurity incident response plan and makes improvements on the response plan based on new learnings. Senior management and Board-level table-top exercises have also been conducted to further prepare and support the Company with responding to and mitigating the effects of a cybersecurity incident. The Company has further implemented a business continuity and disaster recovery plan where critical systems are backed-up daily and incrementally and stored in an encrypted format in multiple secure locations.

As of the date of this report, we do not believe that any risks from any cybersecurity threats, including as a result of any previous cybersecurity incidents, have materially affected or are reasonably likely to affect us, including our business strategy, results of operations or financial condition. That said, as discussed more fully under Part I, Item 1A. “Risk Factors – Risks Related to our Operations”, these potential threats pose a risk to the security of our systems and networks and the confidentiality, availability and integrity of our data. Cybersecurity attacks could also include attacks targeting customer data or the security, integrity and/or reliability of the hardware and software installed in our products. It is possible that our information technology systems and networks, or those managed or provided by third parties, could have vulnerabilities, which could go unnoticed for a period of time. While various procedures and controls have been and are being utilized to mitigate such risks, there can be no guarantee that the actions and controls we have implemented and are implementing, or which we cause or have caused third-party service providers to implement, will be sufficient to protect and mitigate associated risks to our systems, information or other property.

Item 2. Properties

Our United States executive headquarters are located in Tampa, Florida, and consist of approximately 88,000 square feet of leased office space at two sites. Our Canadian executive offices are located in a single leased site in Concord, Ontario. As of December 31, 2023, we owned and leased the following number of properties, by reportable segment:

Our properties in the North American Residential and Architectural segments are distributed across 29 states in the United States and four provinces in Canada, as well as two manufacturing facilities in Mexico and three manufacturing facilities in Chile. Our properties in the Europe segment are distributed across the United Kingdom, as well as one manufacturing facility in Ireland. Our material properties in the Corporate and Other category include one manufacturing facility in Malaysia and four support facilities in the United States. As of December 31, 2023, total floor space at our manufacturing facilities was 13.8 million square feet, including 3.2 million square feet in our five molded door facings facilities. In addition to the properties outlined above, we lease one idle manufacturing facility in the United States and own 17,000 acres of forestland in Costa Rica.

We believe that our facilities are suitable to our respective businesses and have production capacity adequate to support our current level of production to meet our customers’ demand. Additional investments in manufacturing facilities are made as appropriate to balance our capacity with our customers’ demand.

Market Information

Our common shares are listed on the New York Stock Exchange under the symbol "DOOR."

Holders

As of February 27, 2024, we had one record holder of our common shares, Cede & Co., the nominee of the Depository Trust Corporation.

Dividends

We do not intend to pay any cash dividends on our common shares for the foreseeable future and instead may retain earnings, if any, for future operations and expansion, share repurchases or debt repayments, among other things. Any decision to declare and pay dividends in the future will be made at the discretion of our Board of Directors and will depend on, among other things, our results of operations, liquidity requirements, financial condition, contractual restrictions and other factors that our Board of Directors may deem relevant. In addition, our ability to pay dividends is limited by covenants in our Term Loan Facility, in our ABL Facility and in the indenture governing our senior notes. Future agreements may also limit our ability to pay dividends. See Note 9 to our audited consolidated financial statements contained elsewhere in this Annual Report for restrictions on our ability to pay dividends.

Under the Arrangement Agreement, we may not declare, set aside or pay any dividend or other distribution (whether in cash, shares, or property or any combination thereof) in respect of any shares of capital stock without obtaining Owens Corning's approval (which may not be unreasonably withheld, conditioned, or delayed).

Repurchases of Equity Securities by the Issuer and Affiliated Purchasers

During the three months ended December 31, 2023, we repurchased 83,528 of our common shares in the open market.

	Total Number of Shares Purchased	Average Price Paid per Share		Total Number of Shares Purchased as Part of Publicly Announced Plans or Programs	Approximate Dollar Value of Shares that May Yet be Purchased Under the Plans or Programs

Total	83,528	$	88.88	83,528

The Company's Board of Directors approved five share repurchase authorizations, the most recent being an incremental $200.0 million share repurchase program approved on February 21, 2022. Under this program, the Company may repurchase shares from time to time. The timing and actual number of shares repurchased will depend on a variety of factors, including price, general business and market conditions and alternate uses of capital. The share repurchase program may be effected through Rule 10b5-1 plans, open market purchases, each in compliance with Rule 10b-18 under the Exchange Act, or through privately negotiated transactions. The program may be suspended or discontinued at any time and does not have an expiration date. The Arrangement Agreement with Owens Corning restricts our ability to repurchase our shares and therefore our share repurchase program is currently suspended through February 8, 2025, other than for the repurchase of shares associated with tax withholding requirements for share-based compensation.

The Company entered into an accelerated share repurchase ("ASR") transaction during the first quarter of 2022 with a third-party financial institution for the repurchase of $100.0 million of its outstanding common shares. At inception, pursuant to the agreement, the Company paid $100.0 million to the financial institution using cash on hand and received an initial delivery of 848,087 common shares on the same day. The final delivery of 319,678 common shares occurred in the second quarter. The $100.0 million ASR transaction was therefore completed in the second quarter of 2022 with a total delivery of 1,167,765 common shares at a volume-weighted average price ("VWAP") per share minus an agreed upon discount totaling $85.63 per share. The cash paid was reflected as a reduction of equity at the initial delivery of shares and the number of common shares outstanding were reduced at the dates of physical delivery.

As of December 31, 2023, since inception of the repurchase programs we have repurchased $809.7 million of our common shares and have $200.3 million available for repurchase in accordance with our share repurchase programs.

Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations

The following Management's Discussion and Analysis of Financial Condition and Results of Operations ("MD&A") is based upon accounting principles generally accepted in the United States of America and discusses the financial condition and results of operations for Masonite International Corporation for the years ended December 31, 2023, and January 1, 2023. For further discussion of our results of operations for the years ended January 1, 2023, and January 2, 2022, see "Management’s Discussion and Analysis of Financial Condition and Results of Operations" in Part II, Item 7 of our Annual Report on Form 10-K for the year ended January 1, 2023, which was filed with the SEC on February 28, 2023, and which is incorporated herein by reference. In this MD&A, "Masonite," "we," "us," "our" and the "Company" refer to Masonite International Corporation and its subsidiaries.

This discussion should be read in conjunction with the consolidated financial statements and related notes included elsewhere in this Annual Report on Form 10-K. The following discussion should also be read in conjunction with the disclosure under "Special Note Regarding Forward Looking Statements" and Part I, Item 1A, "Risk Factors" elsewhere in this Annual Report on Form 10-K. Our actual results could differ materially from the forward-looking statements as a result of these risks and uncertainties.

Overview

We are a leading global designer, manufacturer, marketer and distributor of interior and exterior doors and door systems for the new construction and repair, renovation and remodeling sectors of the residential and non-residential building construction markets. Since 1925, we have provided our customers with innovative products and superior service at compelling values. Through innovative door solutions, a better door buying experience for our customers and partners and advanced manufacturing and service delivery, we deliver a commitment of Doors That Do MoreTM.

We market and sell our products to remodeling contractors, builders, homeowners, retailers, dealers, lumberyards, commercial and general contractors and architects through well-established wholesale, retail and direct distribution channels as part of our cross-merchandising strategy. Customers are provided a broad product offering of interior and exterior doors and entry systems at various price points. We manufacture an extensive range of interior and exterior doors in a wide array of designs, materials and sizes. Our interior doors are made with wood and related materials such as hardboard (including wood composite molded and flat door facings). Our exterior doors are made primarily of steel, fiberglass or composite materials. Our residential doors are molded panel, flush, stile and rail, steel or fiberglass.

We operate 64 manufacturing and distribution facilities in seven countries in North America, South America, Europe and Asia, which are strategically located to serve our customers through multiple distribution channels. These distribution channels include: (i) direct distribution to retail home center customers; (ii) one-step distribution that sells directly to homebuilders and contractors; and (iii) two-step distribution through wholesale distributors. For retail home center customers, numerous door fabrication facilities provide value-added fabrication and logistical services, including pre-finishing and store delivery of pre-hung interior and exterior doors. We believe our ability to provide: (i) a broad product range; (ii) frequent, rapid, on-time and complete delivery; (iii) consistency in products and merchandising; (iv) national service; and (v) special order programs enables retail customers to increase comparable store sales and helps to differentiate us from our competitors. We believe investments in innovative new product manufacturing and distribution capabilities, coupled with an ongoing commitment to operational excellence, provide a strong platform for future growth.

Our reportable segments are currently organized and managed principally by end market: North American Residential, Europe and Architectural. In the year ended December 31, 2023, we generated net sales of $2,244.9 million or 79.3%, $247.0 million or 8.7% and $323.4 million or 11.4% in our North American Residential, Europe and Architectural segments, respectively. See "Segment Information" below for a description of our reportable segments.

During 2023, we continued to experience lower end market demand and negative impacts from macro-economic conditions such as rising interest rates, higher energy and fuel costs and unfavorable consumer sentiment. Base volumes decreased in our North American Residential segment due to expected new housing softness and declines in the residential repair, renovation and remodeling channel compared to the prior year. Consumer sentiment and inflationary pressures continued to negatively impact our Europe segment. Net sales growth in the Architectural segment was largely driven by increases in average unit price. The extent to which interest rates, supply chain disruptions, rising energy and fuel costs, consumer sentiment and global economic pressures impact our business, results of operations and financial condition will depend on future developments, which are highly uncertain and cannot be predicted.

MASONITE INTERNATIONAL CORPORATION

The Acquisition

On February 8, 2024, we entered into an Arrangement Agreement (the “Arrangement Agreement”) with Owens Corning pursuant to which, subject to the terms and conditions of the Arrangement Agreement, Owens Corning, through Purchaser, agreed to acquire the Company for $133.00 per Share in an all-cash transaction. Pursuant to the Arrangement Agreement, following consummation of the Acquisition, the Company will be a wholly owned subsidiary of Owens Corning.

Pursuant to the terms of the Arrangement Agreement, and subject to the terms and conditions set forth therein, at the Effective Time, each Share (other than any Share that is held by Owens Corning or any of its subsidiaries or any Share as to which dissent rights have been properly exercised by the holder thereof in accordance with British Columbia law) issued and outstanding immediately prior to the Effective Time will be cancelled and automatically converted into the right to receive $133.00 in cash, without interest.

If the Arrangement Agreement is terminated under certain specified circumstances, we or Owens Corning will be required to pay a termination fee. We will be required to pay Owens Corning a termination fee of $75.0 million under specified circumstances, including (a) termination of the Arrangement Agreement in connection with our entry into an agreement with respect to a Superior Proposal (as defined in the Arrangement Agreement) prior to us receiving stockholder approval of the Acquisition, (b) termination by Owens Corning upon an Adverse Recommendation Change (as defined in the Arrangement Agreement), or (c) termination in certain circumstances by either Owens Corning or us upon failure to obtain Masonite Shareholder Approval (as defined in the Arrangement Agreement) or by Owens Corning if we breach our representations, warranties or covenants in a manner that would result in a failure of an applicable closing condition to be satisfied and, if curable, we fail to cure such breach during specific time periods, in each case, if certain other conditions are met. Owens Corning will be required to pay us a reverse termination fee under specified circumstances, including termination of the Arrangement Agreement due to a permanent injunction arising from Competition Laws (as defined in the Arrangement Agreement) when we are not then in material breach of any provision of the Arrangement Agreement and if certain other conditions are met, in an amount equal to $150.0 million.

The consummation of the Acquisition is subject to customary closing conditions, including, among others, (1) the adoption of a resolution approving the Acquisition by at least two-thirds of the votes cast on such resolution by our stockholders entitled to vote thereon and represented in person or by proxy at the applicable special meeting of our stockholders, (2) the issuance of interim and final orders by the Supreme Court of British Columbia approving the Acquisition, (3) the expiration or termination of any applicable waiting period or periods under the Hart-Scott-Rodino Antitrust Improvements Act of 1976 (as amended) and the receipt of certain required regulatory clearances and approvals in other jurisdictions under applicable antitrust and foreign direct investment laws and regulations, including in Canada, Mexico and the United Kingdom, and (4) absence of any law, injunction, order or other judgment prohibiting, rendering illegal or permanently enjoining the consummation of the Acquisition. Each party’s obligation to consummate the Acquisition is also subject to the accuracy of the other party’s representations and warranties contained in the Arrangement Agreement (subject, with specified exceptions, to materiality or “Material Adverse Effect” standards), the other party’s performance of its covenants and agreements in the Arrangement Agreement in all material respects, and in the case of Purchaser’s obligation to consummate the Acquisition, the absence of any “Material Adverse Effect” relating to us.

Key Factors Affecting Our Results of Operations

Product Demand

There are numerous factors that influence overall market demand for our products. Demand for new homes, home improvement products and other building construction products have a direct impact on our financial condition and results of operations. Demand for our products may be impacted by changes in global economic conditions, including inflation, deflation, interest rates, availability of capital, supply chain constraints, consumer spending rates, energy availability and costs and the effects of governmental initiatives to manage economic conditions. Additionally, trends in residential new construction, repair, renovation and remodeling and architectural building construction may directly impact our financial performance. Accordingly, the following factors may have a direct impact on our business in the countries and regions in which our products are sold:

•the strength of the economy;

32

MASONITE INTERNATIONAL CORPORATION

•the amount and type of residential and commercial construction;

•housing sales and home values;

•the age of existing home stock, home vacancy rates and foreclosures;

•non-residential building occupancy rates;

•increases in the cost of raw materials or wages or any shortage in supplies or labor;

•the availability and cost of credit;

•employment rates and consumer confidence; and

•demographic factors such as immigration and migration of the population and trends in household formation.

Product Pricing and Mix

The building products industry is highly competitive, and we therefore face pressure on sales prices of our products. In addition, our competitors may adopt more aggressive sales policies and devote greater resources to the development, promotion and sale of their products than we do, which could result in a loss of customers. Our business in general is subject to changing consumer and industry trends, demands and preferences. Trends within the industry change often and our failure to anticipate, identify or quickly react to changes in these trends could lead to, among other things, rejection of a new product line and reduced demand and price reductions for our products, which could materially and adversely affect us. Changes in consumer preferences may also lead to increased demand for our lower margin products relative to our higher margin products, which could reduce our future profitability.

Business Wins and Losses

Our customers consist mainly of wholesalers and retail home centers. In fiscal year 2023, our top ten customers together accounted for approximately 50% of our net sales and our top customer, The Home Depot, Inc. accounted for approximately 20% of our net sales in fiscal year 2023. Net sales from customers that have accounted for a significant portion of our net sales in past periods, individually or as a group, may not continue in future periods, or if continued, may not reach or exceed historical levels in any period. Certain customers perform periodic product line reviews to assess their product offerings, which have, on past occasions, led to business wins and losses. In addition, as a result of competitive bidding processes, we may not be able to increase or maintain the margins at which we sell our products to our customers.

Organizational Restructuring

Over the past several years, we have engaged in a series of restructuring programs related to exiting certain geographies and non-core businesses, consolidating certain internal support functions and engaging in other actions designed to reduce our cost structure and improve productivity. These initiatives primarily consist of severance actions and lease termination costs. Management continues to evaluate our business; therefore, in future years, there may be additional provisions for new plan initiatives, as well as changes in previously recorded estimates, as payments are made or actions are completed. Asset impairment charges were also incurred in connection with these restructuring actions for those assets sold, abandoned or made obsolete as a result of these programs.

In December 2023, we began implementing a plan to improve overall business performance that includes the optimization of our manufacturing capacity and reduction of our overhead and selling, general and administration workforce primarily in our Europe reportable segment (collectively, the "2024 Plan"). The optimization of our manufacturing capacity involves specific plants in the Europe segment and costs associated with the closure of these plants and related headcount reductions. Costs associated with the 2024 Plan include severance and closure charges and will continue throughout 2024. As of December 31, 2023, we expect to incur approximately $6 million to $9 million of additional charges related to the 2024 Plan. The actions taken as part of the 2024 Plan are expected to increase our annual earnings and cash flows by approximately $4 million to $6 million.

In December 2022, we began implementing a plan to improve overall business performance that includes the optimization of our manufacturing capacity and reduction of our overhead and selling, general and administration workforce primarily in our North American Residential reportable segment as well as actions in the Architectural reportable segment and in our head offices (collectively, the "2022 Plan"). The optimization of our manufacturing capacity involves specific plants in the North American Residential segment and costs associated with the closure of these plants and related headcount reductions. Costs associated with the 2022 Plan include severance and closure charges

33

MASONITE INTERNATIONAL CORPORATION

and will continue throughout 2024. The actions taken as part of the 2022 Plan are substantially complete and the annual earnings and cash flow savings realized were materially in line with expectations.

In May 2021, we initiated further actions to improve overall business performance including the reorganization of our specialty door manufacturing capacity in our Architectural reportable segment. The reorganization of our manufacturing capacity involves specific facilities in the Architectural segment and costs associated with the reorganization of these facilities, which resulted in the closure of one existing stile and rail facility and related headcount reductions beginning in the second quarter of 2021 (collectively, the "2021 Plan"). Costs associated with the 2021 Plan include severance and closure charges and continued through 2021. The actions taken as part of the 2021 Plan are substantially complete and the annual earnings and cash flow savings realized were materially in line with expectations.

In November 2020, we began implementing a plan to improve overall business performance that includes the reorganization of our manufacturing capacity and a reduction of our overhead and selling, general and administration workforce primarily in our Architectural reportable segment as well as limited actions in the North American Residential reportable segment. The reorganization of our manufacturing capacity involves specific facilities in the Architectural segment and costs associated with the closure of these facilities and related headcount reductions began taking place in the fourth quarter of 2020 (collectively, the "2020 Plan"). Costs associated with the 2020 Plan include severance and closure charges and continued through 2021. The actions taken as part of the 2020 Plan are substantially complete and the annual earnings and cash flow savings realized were materially in line with expectations.

In February 2019, we began implementing a plan to improve overall business performance that includes the reorganization of our manufacturing capacity and a reduction of our overhead and selling, general and administration workforce across all of our reportable segments and in our head offices. The reorganization of our manufacturing capacity involves specific plants in the North American Residential and Architectural segments and costs associated with the closure of these plants and related headcount reductions began taking place in the first quarter of 2019 (collectively, the "2019 Plan"). Costs associated with the 2019 Plan include severance, retention and closure charges and continued through 2021. In the fourth quarter of 2019, we initiated additional restructuring actions related to both manufacturing capacity and reduction of our overhead and selling, general and administration workforce. The actions taken as part of the 2019 Plan are substantially complete and the annual earnings and cash flow savings realized were materially in line with expectations.

Inflation

In 2022 and 2023, we realized higher costs across the various materials we purchase as a result of macroeconomic factors as well as increased logistics costs, wages, anti-dumping and countervailing duties and energy and fuel costs. Additionally, rising interest rates may impact the ability of end consumers to purchase our products. Our profitability, margins and net sales could be adversely affected if we are not able to pass these costs on to our customers or otherwise mitigate the impact of these inflationary pressures.

MASONITE INTERNATIONAL CORPORATION

Acquisitions and Divestitures

We are pursuing a strategic initiative of optimizing our global business portfolio. On a continual basis, we evaluate and consider strategic acquisitions, divestitures and joint ventures to create shareholder value and enhance financial performance.

Acquisitions

•On October 19, 2023, the Company completed the acquisition of all of the issued and outstanding limited liability company interests of Fleetwood Aluminum Products, LLC (“Fleetwood”), for total consideration of approximately $279.1 million. The total consideration was funded with a combination of cash on hand and borrowings under the ABL Facility. Fleetwood is a leading designer and manufacturer of premium, aluminum-framed glass door and window solutions for luxury homes.

•On January 3, 2023, we completed the acquisition of 100% of the outstanding equity of EPI Holdings, Inc. ("Endura"), for total consideration of approximately $403.3 million. The total consideration was funded with borrowings under our Term Loan Facility and ABL Facility. Endura is a leading innovator and manufacturer of high-performance door frames and door system components in the United States.

Divestitures

•As previously disclosed, we are actively reviewing strategic alternatives for our Architectural segment, including a potential sale of some or all of the business. There can be no assurance that a potential transaction will be consummated or on what terms. The Arrangement Agreement with Owens Corning restricts our ability to dispose of certain businesses, properties or assets of the Company without Owens Corning’s prior consent. If a transaction is consummated, depending on the sale price, we could incur an impairment charge related to the book value of the segment's assets. This charge could be material.

•During the fourth quarter of 2022, we completed the liquidation of our legal entity in Turkey. As a result, we recognized $0.9 million in loss on disposal of subsidiaries.

•On June 14, 2021, we completed the sale of all of the capital stock of our Czech business for consideration of $7.0 million, net of cash disposed. The divestiture of this business resulted in a loss on sale of subsidiaries of $8.6 million, which was recognized during the second quarter of 2021 in the Europe segment.

Net sales in the year ended December 31, 2023, were $2,830.7 million, a decrease of $61.0 million or 2.1% from $2,891.7 million in the year ended January 1, 2023. Foreign exchange rate fluctuations negatively impacted net sales in the year ended December 31, 2023 by $9.7 million. The 2023 acquisitions increased net sales by $248.1 million or 8.6%. Excluding the exchange rate impact and our 2023 acquisitions, net sales would have decreased by $299.4 million or 10.4% due to changes in volume, average unit price and sales of components. Lower base volume decreased net sales by $400.0 million or 13.8% in 2023 compared to 2022. Net sales of components to external customers decreased $17.6 million or 0.6% in 2023 compared to 2022. Average unit price in 2023 increased net sales by $118.2 million or 4.1% compared to 2022.

North American Residential

Net sales to external customers from facilities in the North American Residential segment in the year ended December 31, 2023, were $2,244.9 million, a decrease of $38.7 million or 1.7% from $2,283.6 million in the year ended January 1, 2023. Foreign exchange rate fluctuations negatively impacted net sales in 2023 by $9.3 million. The 2023 acquisitions increased net sales by $248.1 million or 10.9%. Excluding the exchange rate impact and our 2023 acquisitions, net sales would have decreased by $277.5 million or 12.2% due to changes in volume, average unit price and sales of components. Lower base volume decreased net sales by $340.0 million or 14.9% in 2023 compared to 2022 due to softening end market demand in new construction and residential repair, renovation and remodeling channels. Average unit price increased net sales in 2023 by $61.1 million or 2.7% compared to 2022. Net sales of components to external customers were $1.4 million higher in 2023 compared to 2022.

Europe

Net sales to external customers from facilities in the Europe segment in the year ended December 31, 2023, were $247.0 million, a decrease of $33.8 million or 12.0% from $280.8 million in the year ended January 1, 2023. Net sales in 2023 were positively impacted by $1.3 million as a result of foreign exchange fluctuations. Excluding this exchange rate impact, net sales would have decreased by $35.1 million or 12.5% due to changes in volume, average unit price and sales of components. Lower base volume decreased net sales by $32.0 million or 11.4% compared to 2022 due to overall economic trends in the United Kingdom. Net sales of components to external customers were $2.9 million lower in 2023 compared to 2022. Average unit price decreased net sales in 2023 by $0.2 million or 0.1% compared to 2022.

Architectural

Net sales to external customers from facilities in the Architectural segment in the year ended December 31, 2023, were $323.4 million, an increase of $16.4 million or 5.3% from $307.0 million in the year ended January 1, 2023. Net sales in 2023 were negatively impacted by $1.6 million as a result of foreign exchange fluctuations. Excluding this exchange rate impact, net sales would have increased by $18.0 million or 5.9% due to changes in volume, average unit price and sales of components. Average unit price increased net sales in 2023 by $56.4 million or 18.4% compared to 2022. Lower base volume decreased net sales in 2023 by $28.0 million or 9.1% compared to 2022. Net sales of components to external customers were $10.4 million lower in 2023 compared to 2022.

Cost of Goods Sold

Our cost of goods sold is comprised of the cost to manufacture products for our customers and includes the cost of materials, direct labor, overhead, distribution and depreciation associated with assets used to manufacture products. Research and development costs are primarily included within cost of goods sold. We incur significant fixed and variable overhead at our global component locations that manufacture interior molded door facings.

Cost of goods sold as a percentage of net sales was 76.5% and 76.7% for the years ended December 31, 2023, and January 1, 2023, respectively. Material cost of sales and distribution as a percentage of net sales decreased by 3.1% and 0.4% in 2023 compared to 2022. The decrease in material cost of sales as a percentage of net sales was driven by lower inbound freight, tariff reductions and material cost savings projects. Distribution as a percentage of net sales decreased due to outbound freight deflation. Overhead, direct labor and depreciation as a percentage of net sales increased by 2.1%, 0.7% and 0.5%, respectively, compared to the 2022 period. Overhead as a percentage of net sales increased due to higher factory costs and wage inflation as compared to 2022. Direct labor as a percentage of net sales

37

MASONITE INTERNATIONAL CORPORATION

increased due to higher manufacturing wage and benefit inflation. The increase in depreciation as a percentage of net sales was driven by our 2023 acquisitions.

Selling, General and Administration Expenses

Selling, general and administration ("SG&A") expenses primarily include the costs for our sales organization and support staff at various plants and corporate offices. These costs include personnel costs for payroll, related benefits and stock based compensation expense; professional fees; depreciation and amortization of our non-manufacturing equipment and assets; environmental, health and safety costs; advertising expenses and rent and utilities related to administrative office facilities. In the year ended December 31, 2023, selling, general and administration expenses, as a percentage of net sales, were 14.5%, compared to 11.9% in the year ended January 1, 2023.

Selling, general and administration expenses in the year ended December 31, 2023, were $411.6 million, an increase of $67.0 million from $344.6 million in the year ended January 1, 2023. The overall increase was driven by incremental SG&A from the 2023 acquisitions of $42.7 million; a $12.3 million increase in non-cash items including loss (gain) on disposal of property, plant and equipment, depreciation and amortization, deferred compensation and share based compensation; $5.5 million in acquisition and due diligence related costs and legal costs related to the settlement of Canada class action litigation; a $5.2 million increase in professional and other fees to support growth; and a $1.3 million increase in personnel costs primarily driven by increased incentive compensation.

Restructuring Costs

Restructuring costs in the year ended December 31, 2023, were $10.1 million, compared to $1.9 million in the year ended January 1, 2023. Restructuring costs in 2023 primarily related to severance and closure costs associated with the 2022 Plan. Restructuring costs in the prior year period primarily related to closure costs associated with the 2022 Plan.

Asset Impairment

Asset impairment charges in the year ended December 31, 2023 were $33.1 million compared to none in the year ended January 1, 2023. Asset impairment charges in 2023 resulted from a goodwill impairment charge recorded in our Europe reporting unit. Refer to Note 14. Asset Impairment, in Item 8 of this Annual Report for additional information.

Loss on Disposal of Subsidiaries

Loss on disposal of subsidiaries represents the difference between proceeds received upon disposition and the book value of a subsidiary which has been divested and was excluded from treatment as a discontinued operation. Also included in loss on disposal of subsidiaries is recognition of the cumulative translation adjustment out of accumulated other comprehensive loss. Loss on disposal of subsidiaries was zero in the year ended December 31, 2023, compared to $0.9 million in the year ended January 1, 2023. The prior year loss arose as a result of the liquidation of our legal entity in Turkey and is comprised of $0.7 million relating to the recognition of cumulative translation adjustment out of accumulated other comprehensive loss and $0.2 million relating to the write-off of net assets.

Interest Expense, Net

Interest expense, net, in the year ended December 31, 2023, was $50.8 million, compared to $41.3 million in the year ended January 1, 2023. The increase in interest expense, net is primarily due to the incremental borrowings under the Term Loan Facility and ABL Facility related to the Endura and Fleetwood acquisitions.

Other (Income) Expense, Net

Other (income) expense, net includes profits and losses related to our non-majority owned unconsolidated subsidiaries that we recognize under the equity method of accounting, unrealized gains and losses on foreign currency remeasurements, pension settlement charges and other miscellaneous non-operating expenses. Other (income) expense, net, in the year ended December 31, 2023, was $2.1 million of income, compared to $5.0 million in the year ended January 1, 2023. The change in other (income) expense, net is primarily due to a change in non-recurring expense.

38

MASONITE INTERNATIONAL CORPORATION

Income Tax Expense

Income tax expense in the year ended December 31, 2023, was $40.9 million, compared to $71.8 million in the year ended January 1, 2023. The decrease in income tax expense is primarily due to the decrease in the overall pre-tax earnings and the mix of income and losses within the tax jurisdictions in which we operate.

Segment Information

Our reportable segments are organized and managed principally by end market: North American Residential, Europe and Architectural. The Corporate & Other category includes unallocated corporate costs and the results of immaterial operating segments that were not aggregated into any reportable segment. In addition to similar economic characteristics, we also consider the following factors in determining the reportable segments: the nature of business activities, the management structure directly accountable to our chief operating decision maker for operating and administrative activities, availability of discrete financial information and information presented to the Board of Directors and investors.

Our management reviews net sales and Adjusted EBITDA (as defined below) to evaluate segment performance and allocate resources. Net assets are not allocated to the reportable segments. Adjusted EBITDA is a non-GAAP financial measure which does not have a standardized meaning under GAAP and is unlikely to be comparable to similar measures used by other companies. Adjusted EBITDA should not be considered as an alternative to either net income or operating cash flows determined in accordance with GAAP. Adjusted EBITDA is defined as net income (loss) attributable to Masonite adjusted to exclude the following items:

•    depreciation;

•    amortization;

•    share based compensation expense;

•    loss (gain) on disposal of property, plant and equipment;

•    registration and listing fees;

•    restructuring costs (benefit);

•    asset impairment;

•    loss (gain) on disposal of subsidiaries;

•    interest expense (income), net;

•    loss on extinguishment of debt;

•    other (income) expense, net;

•    income tax expense (benefit);

•    other items;

•    loss (income) from discontinued operations, net of tax; and

•    net income (loss) attributable to non-controlling interest.

This definition of Adjusted EBITDA differs from the definitions of EBITDA contained in the indenture governing the 2030 Notes, the 2028 Notes and the credit agreements governing the Term Loan Facility and the ABL Facility. Adjusted EBITDA is used to evaluate and compare the performance of the segments and it is one of the primary measures used to determine employee incentive compensation.

We believe that Adjusted EBITDA, from an operations standpoint, provides an appropriate way to measure and assess segment performance. Our management team has established the practice of reviewing the performance of each segment based on the measures of net sales and Adjusted EBITDA. We believe that Adjusted EBITDA is useful to users of the consolidated financial statements because it provides the same information that we use internally to evaluate and compare the performance of the segments and it is one of the primary measures used to determine employee incentive compensation.

MASONITE INTERNATIONAL CORPORATION

Adjusted EBITDA in our North American Residential segment decreased $20.9 million, or 4.5%, to $440.9 million in the year ended December 31, 2023, from $461.8 million in the year ended January 1, 2023. Adjusted EBITDA in the North American Residential segment included corporate allocations of shared costs of $93.3 million and $89.5 million in 2023 and 2022, respectively. The allocations generally consist of certain costs of human resources, legal, finance, information technology, research and development, marketing and share based compensation.

Adjusted EBITDA in our Europe segment decreased $18.1 million, or 62.8%, to $10.7 million in the year ended December 31, 2023, from $28.8 million in the year ended January 1, 2023. Adjusted EBITDA in the Europe segment included corporate allocations of shared costs of $7.1 million and $6.8 million in 2023 and 2022, respectively. The allocations generally consist of certain costs of human resources, legal, finance, information technology, marketing and share based compensation.

Adjusted EBITDA in our Architectural segment increased $19.2 million or 512.5% to a gain of $15.5 million in the year ended December 31, 2023, from a loss of $3.7 million in the year ended January 1, 2023. Adjusted EBITDA in the Architectural segment also included corporate allocations of shared costs of $10.1 million and $11.4 million in 2023 and 2022, respectively. The allocations generally consist of certain costs of human resources, legal, finance, information technology, research and development, marketing and share based compensation.

Liquidity and Capital Resources

Our liquidity needs for operations vary throughout the year. Our principal sources of liquidity are cash flows from operating activities, the borrowings under our ABL Facility, an accounts receivable sales program with a third party ("AR Sales Program") and our existing cash balance. Our anticipated uses of cash in the near term include working capital needs and capital expenditures. As of December 31, 2023, we did not have any material commitments for capital expenditures. On a continual basis, we evaluate and consider strategic acquisitions, divestitures and joint ventures to create shareholder value and enhance financial performance.

We believe that our cash balance on hand, future cash generated from operations, the use of our AR Sales Program, our ABL Facility and our Term Loan Facility along with our ability to access the capital markets will provide adequate liquidity for the foreseeable future. As of December 31, 2023, we had $137.4 million of cash and cash equivalents, availability under our ABL Facility of $273.6 million and availability under our AR Sales Program of $25.9 million. Subject to certain exceptions, the Arrangement Agreement with Owens Corning restricts our ability to borrow more than $40.0 million under the ABL Facility in the aggregate without the prior consent of Owens Corning. We do not believe this restriction will impact our liquidity to meet our ongoing working capital and capital expenditure needs.

Cash Flows

Year Ended December 31, 2023, Compared with Year Ended January 1, 2023

Cash provided by operating activities was $407.7 million during the year ended December 31, 2023, compared to $189.2 million during the year ended January 1, 2023. This $218.5 million increase in cash provided by operating activities was due to $255.2 million in cash provided by working capital and other assets and liabilities, partially offset by a $36.7 million decrease in net income attributable to Masonite, adjusted for non-cash and non-operating items in 2023 compared to 2022.

Cash used in investing activities was $733.8 million during the year ended December 31, 2023, compared to $111.1 million during the year ended January 1, 2023. This $622.7 million increase in cash used in investing activities was primarily driven by a $626.8 million increase in cash used in the acquisition of Endura and the acquisition of Fleetwood (net of cash acquired), the absence of $6.3 million of proceeds from the sale of property, plant and equipment, and a $3.3 million increase in cash used in other investing activities, partially offset by $12.0 million of proceeds from repayment of a note receivable and a $1.7 million decrease in cash additions to property, plant and equipment in 2023 compared to 2022.

Cash provided by financing activities was $166.3 million during the year ended December 31, 2023, compared to cash used of $157.4 million during the year ended January 1, 2023. This $323.7 million increase in cash provided by financing activities was driven by a $218.3 million increase in cash provided by debt-related transactions, a $102.9 million decrease in cash used for repurchases of common shares, a $0.8 million decrease in cash used for tax withholding on share based awards and a $1.7 million decrease in distributions to non-controlling interests in 2023 compared to 2022.

MASONITE INTERNATIONAL CORPORATION

Share Repurchases

The Company's Board of Directors approved five share repurchase authorizations, the most recent being an incremental $200.0 million share repurchase program approved on February 21, 2022. Under this program, the Company may repurchase shares from time to time. The timing and actual number of shares repurchased will depend on a variety of factors, including price, general business and market conditions and alternate uses of capital. The share repurchase program may be effected through Rule 10b5-1 plans, open market purchases, each in compliance with Rule 10b-18 under the Exchange Act, or through privately negotiated transactions. The program may be suspended or discontinued at any time and does not have an expiration date. The Arrangement Agreement with Owens Corning restricts our ability to repurchase our shares and therefore our share repurchase program is currently suspended through February 8, 2025, other than for the repurchase of shares associated with tax withholding requirements for share-based compensation.

The Company entered into an accelerated share repurchase ("ASR") transaction during the first quarter of 2022 with a third-party financial institution for the repurchase of $100.0 million of its outstanding common shares. At inception, pursuant to the agreement, the Company paid $100.0 million to the financial institution using cash on hand and received an initial delivery of 848,087 common shares on the same day. The final delivery of 319,678 common shares occurred in the second quarter. The $100.0 million ASR transaction was therefore completed in the second quarter of 2022 with a total delivery of 1,167,765 common shares at a volume-weighted average price ("VWAP") per share minus an agreed upon discount totaling $85.63 per share. The cash paid was reflected as a reduction of equity at the initial delivery of shares and the number of common shares outstanding were reduced at the dates of physical delivery. During the year ended December 31, 2023, we repurchased 517,525 of our common shares in the open market at an aggregate cost of $46.6 million. During the year ended January 1, 2023, we repurchased 1,679,919 of our common shares in the open market at an aggregate cost of $149.5 million.

As of December 31, 2023, since inception of the programs we have repurchased $809.7 million of our common shares and have $200.3 million available for repurchase in accordance with our share repurchase programs.

Other Liquidity Matters

Our cash and cash equivalents balance includes cash held in foreign countries in which we operate. Cash held outside Canada, in which we are incorporated, is free from significant restrictions that would prevent the cash from being accessed to meet our liquidity needs including, if necessary, to fund operations and service debt obligations in Canada. However, earnings from certain jurisdictions are indefinitely reinvested in those jurisdictions. Upon the repatriation of any earnings to Canada, in the form of dividends or otherwise, we may be subject to Canadian income taxes and withholding taxes payable to the various foreign countries. As of December 31, 2023, we do not believe adverse tax consequences exist that restrict our use of cash or cash equivalents in a material manner.

We also routinely monitor the changes in the financial condition of our customers and the potential impact on our results of operations. There has not been a change in the financial condition of a customer that has had a material adverse effect on our results of operations. However, if economic conditions were to deteriorate, it is possible there could be an impact on our results of operations in a future period and this impact could be material.

Accounts Receivable Sales Program

Under the AR Sales Program, we can transfer ownership of eligible trade accounts receivable of certain customers. Receivables are sold outright to a third party who assumes the full risk of collection, without recourse to us in the event of a loss. Transfers of receivables under this AR Sales Program are accounted for as sales. Proceeds from the transfers reflect the face value of the accounts receivable less a discount. Receivables sold under the AR Sales Program are excluded from trade accounts receivable in the consolidated balance sheets and are included in cash flows from operating activities in the consolidated statements of cash flows. The discounts on the sales of trade accounts receivable sold under the AR Sales Program were not material for any of the periods presented and were recorded in selling, general and administration expense within the consolidated statements of income and comprehensive income.

Senior Notes

On July 26, 2021, we issued $375.0 million aggregate principal senior unsecured notes (the "2030 Notes"). The 2030 Notes were issued in a private placement for resale to qualified institutional buyers pursuant to Rule 144A of the Securities Act of 1933, as amended (the "Securities Act"), and to buyers outside of the United States pursuant to

43

MASONITE INTERNATIONAL CORPORATION

Regulation S under the Securities Act. The 2030 Notes bear interest at 3.50% per annum, payable in cash semiannually in arrears on February 15 and August 15 of each year commencing on February 15, 2022, and the principal is due February 15, 2030. The 2030 Notes were issued at par. We received net proceeds of $370.3 million after deducting $4.7 million of debt issuance costs. The debt issuance costs were capitalized as a reduction to the carrying value of debt and are being accreted to interest expense over the term of the 2030 Notes using the effective interest method. The net proceeds from the issuance of the 2030 Notes were used to redeem the remaining $300.0 million aggregate principal amount of the 2026 Notes (as described below), including the payment of related premiums, fees and expenses, with the balance of the proceeds available for general corporate purposes.

Obligations under the 2030 Notes are fully and unconditionally guaranteed, jointly and severally, on a senior unsecured basis, by certain of our directly or indirectly wholly-owned subsidiaries. We may redeem the 2030 Notes under certain circumstances specified therein.

The indenture governing the 2030 Notes contains limited covenants that, among other things, limit our ability and the ability of our subsidiaries to (i) incur certain secured debt, (ii) engage in certain sale and leaseback transactions and (iii) merge or consolidate with other entities. The foregoing limitations are subject to exceptions as set forth in the indenture governing the 2030 Notes. The indenture governing the 2030 Notes contains customary events of default (subject to certain cases to customary grace and cure periods). As of December 31, 2023, we were in compliance with all covenants under the indenture governing the 2030 Notes.

On July 25, 2019, we issued $500.0 million aggregate principal senior unsecured notes (the "2028 Notes"). The 2028 Notes were issued in a private placement for resale to qualified institutional buyers pursuant to Rule 144A under the Securities Act of 1933, as amended (the "Securities Act"), and to buyers outside of the United States pursuant to Regulation S under the Securities Act. The 2028 Notes were issued without registration rights and are not listed on any securities exchange. The 2028 Notes bear interest at 5.375% per annum, payable in cash semiannually in arrears on February 1 and August 1 of each year and the principal is due February 1, 2028. The 2028 notes were issued at par. We received net proceeds of $493.3 million after deducting $6.7 million of debt issuance costs. The debt issuance costs were capitalized as a reduction to the carrying value of debt and are being accreted to interest expense over the term of the 2028 Notes using the effective interest method. The net proceeds from issuance of the 2028 Notes, together with available cash balances, were used to redeem the remaining $500.0 million aggregate principal amount of similar senior unsecured notes.

Obligations under the 2028 Notes are fully and unconditionally guaranteed, jointly and severally, on a senior unsecured basis, by certain of our directly or indirectly wholly-owned subsidiaries. We may redeem the 2028 Notes under certain circumstances specified therein.

The indenture governing the 2028 Notes contains restrictive covenants that, among other things, limit our ability and the ability of our subsidiaries to: (i) incur additional debt and issue disqualified or preferred stock, (ii) make restricted payments, (iii) sell assets, (iv) create or permit restrictions on the ability of our restricted subsidiaries to pay dividends or make other distributions to the parent company, (v) create or incur certain liens, (vi) enter into sale and leaseback transactions, (vii) merge or consolidate with other entities and (viii) enter into transactions with affiliates. The foregoing limitations are subject to exceptions as set forth in the indenture governing the 2028 Notes. In addition, if in the future the 2028 Notes have an investment grade rating from at least two nationally recognized statistical rating organizations, certain of these covenants will be terminated. The indenture governing the 2028 Notes contains customary events of default (subject in certain cases to customary grace and cure periods). As of December 31, 2023, we were in compliance with all covenants under the indenture governing the 2028 Notes.

Term Loan Facility

On December 13, 2022, we and certain of our subsidiaries entered into a new delayed-draw term loan credit agreement (the "Term Loan Credit Agreement") maturing on December 12, 2027 (the "Term Loan Maturity Date"). The Term Loan Credit Agreement provides for a senior secured five-year delayed-draw term loan facility of $250.0 million (the "Term Loan Facility"). Loans under the Term Loan Facility (the "Term Loans") will bear interest at a rate equal to, at our option, (1) the Adjusted Term SOFR Rate (as defined in the Term Loan Credit Agreement) plus an applicable margin of 2.25% or (2) an alternate base rate equal to the greatest of (i) the "Prime Rate" in the U.S. last quoted by The Wall Street Journal, (ii) 0.50% above the greater of the federal funds rate and the rate comprised of both overnight federal funds and overnight eurodollar transactions denominated in Dollars, (iii) 1.00% above the Adjusted Term SOFR

44

MASONITE INTERNATIONAL CORPORATION

Rate for a one month interest period and (iv) 1.00%, plus, in each case, an applicable margin of 1.25%, subject to, in each of cases (1) and (2), an agreed interest rate floor. The Term Loans are repayable in equal quarterly installments for an annual aggregate amortization payment equal to 15% of the aggregate principal amount of the Term Loans, with the balance of the principal being due on the Term Loan Maturity Date.

The Term Loan Credit Agreement also includes a quarterly ticking fee of 25 basis points per annum payable to the lenders under the Term Loan Facility beginning on January 3, 2023 (the "Closing Date") in respect of the unutilized commitments thereunder. As a result of the incurrence of the Term Loans on the Closing Date such ticking fees were not (and shall not be) payable to the Lenders.

Obligations under the Term Loan Credit Agreement are fully and unconditionally guaranteed, jointly and severally, by us and by certain of our directly or indirectly wholly-owned subsidiaries organized in the United States and are secured by the equity in, and substantially all the assets of, such subsidiaries. The Term Loans were funded in an amount of $250.0 million and applied to finance a portion of the consideration payable in connection with the consummation of the Endura acquisition on January 3, 2023.

The Term Loan Credit Agreement contains restrictive covenants that, among other things, limit our ability and the ability of our subsidiaries to: (i) pay dividends on our common shares and make other restricted payments, (ii) make investments and acquisitions, (iii) engage in transactions with our affiliates, (iv) sell assets, (v) merge, (vi) incur additional debt and (vii) create liens. The Term Loan Credit Agreement includes certain exceptions and exemptions under the restricted payment, investment, dispositions, liens and indebtedness covenants.

The Term Loan Credit Agreement requires us to maintain at all times a total leverage ratio of no more than 4.50:1.00. The Term Loan Credit Agreement contains change of control provisions and certain customary affirmative covenants and events of default. As of December 31, 2023, we were in compliance with all covenants under the credit agreement governing the Term Loan Facility and there were no amounts outstanding.

ABL Facility

On January 31, 2019, we and certain of our subsidiaries entered into a $250.0 million asset-based revolving credit facility (the "ABL Facility") maturing on January 31, 2024, which replaced the previous facility. On October 28, 2022, we and certain of our subsidiaries entered into an amendment to the "ABL Facility" which, among other things, (i) increased the revolving credit commitments available thereunder by $100.0 million to an aggregate amount of $350.0 million and (ii) replaced the LIBOR-based interest rate applicable to borrowings thereunder in U.S. dollars with an interest rate based on the sum of (x) a "Term SOFR" rate published by the CME Group Benchmark Administration Limited (CBA) plus (y) 10 basis points ("Adjusted Term SOFR"). Additionally, on December 12, 2022, we and certain of our subsidiaries entered into an amendment to the ABL Facility, which, among other things, extended the maturity of the ABL Facility from January 31, 2024 to December 12, 2027. The terms of the ABL Facility remained otherwise substantially unchanged. In connection with the acquisition of Endura on January 3, 2023, the Company borrowed $100.0 million under the ABL Facility in order to fund a portion of the cash consideration paid. During the first quarter of 2023, we repaid all amounts outstanding under the ABL Facility. On October 18, 2023, we borrowed $85.0 million under the ABL Facility in order to fund a portion of the cash consideration paid in connection with the acquisition of Fleetwood. Subsequently, during the fourth quarter of 2023, we repaid all amounts outstanding under the ABL Facility.

Borrowings under the ABL Facility bear interest at a rate equal to, at our option, (i) the United States, Canadian and United Kingdom Base Rate (each as defined in the credit agreement relating to the ABL Facility, the "Amended and Restated Credit Agreement") plus a margin ranging from 0.25% to 0.50% per annum, or (ii) the Term SOFR or BA Rate (each as defined in the Amended and Restated Credit Agreement), plus a margin ranging from 1.25% to 1.50% per annum. In addition to paying interest on any outstanding principal under the ABL Facility, a commitment fee is payable on the undrawn portion of the ABL Facility in an amount equal to 0.25% per annum of the average daily balance of unused commitments during each calendar quarter.

The ABL Facility contains various customary representations, warranties and covenants by us that, among other things, and subject to certain exceptions, restricts our ability and the ability of our subsidiaries to: (i) pay dividends on our common shares and make other restricted payments, (ii) make investments and acquisitions, (iii) engage in transactions with our affiliates, (iv) sell assets, (v) merge and (vi) create liens. The ABL Facility, among other things, (i) permits us to incur unlimited unsecured debt as long as such debt does not contain covenants or default provisions that are more restrictive than those contained in the ABL Facility, (ii) permits us to incur debt as long as the pro forma

45

MASONITE INTERNATIONAL CORPORATION

secured leverage ratio is less than 4.5 to 1.0, and (iii) adds certain additional exceptions and exemptions under the restricted payment, investment and indebtedness covenants (including increasing the amount of certain debt permitted to be incurred under existing exceptions). As of December 31, 2023, we were in compliance with all covenants under the credit agreement governing the ABL Facility and there were no amounts outstanding under the ABL Facility.

Critical Accounting Policies and Estimates

Our significant accounting policies are fully disclosed in our annual consolidated financial statements included elsewhere in this Annual Report. We consider the following policies to be most critical in understanding the judgments that are involved in preparing our consolidated financial statements.

Business Acquisition Accounting

We account for business combinations under Financial Accounting Standard Board ("FASB") Accounting Standards Codification 805 "Business Combinations" using the acquisition method of accounting. We allocate the purchase price of our business acquisitions based on the fair value of identifiable tangible and intangible assets. Management estimates the fair value of assets and liabilities with the assistance of a third-party specialist, using a combination of the market, cost and income valuation methods. These valuation methods use inputs estimated by management, such as revenue and adjusted EBITDA forecasts, attrition and discount rates, projected capital spending, and estimates for sales costs, among others. The excess of the purchase price over the estimated fair value is recorded as goodwill. All acquisition costs are expensed as incurred. Upon acquisition, the accounts and results of operations are consolidated as of and after the acquisition date. The Company may adjust the amounts recognized for a business combination within the allowable measurement period that cannot exceed one year after the acquisition date. Any such adjustments would generally be recorded as increases or decreases to the goodwill recognized in the transaction. Upon the conclusion of a business acquisition's measurement period or final determination of the values of assets acquired or liabilities assumed, whichever comes first, any subsequent adjustments are recorded to our consolidated statements of operations.

Goodwill

Goodwill is not amortized but instead is tested annually for impairment on the last day of fiscal November, or more frequently if events or changes in circumstances indicate the carrying amount may not be recoverable. The test for impairment is performed at the reporting unit level by comparing the reporting unit’s carrying amount to its fair value. Possible impairment of goodwill is first analyzed using qualitative factors such as macroeconomic and market conditions, changing costs and actual and projected performance, amongst others, to determine whether it is more likely than not that the book value of the reporting unit exceeds its fair value. If it is determined more likely than not that the book value exceeds fair value, a quantitative analysis is performed to test for impairment. When quantitative steps are determined necessary, the fair values of the reporting units are estimated through the use of discounted cash flow analyses and market multiples. If the carrying amount exceeds fair value, then goodwill is impaired. Any impairment in goodwill is measured as the excess of the carrying value of goodwill over the fair value. The inputs utilized to derive projected cash flows are subject to significant judgments and uncertainties. As such, the realized cash flows could differ significantly from those estimated. We performed a quantitative annual impairment test of our Europe reporting unit and determined that goodwill was impaired. Refer to Note 14. Asset Impairment, in Item 8 of this Annual Report for additional information. We performed a qualitative annual impairment test of our North American Residential reporting unit during the fourth quarter of 2023 and determined that goodwill was not impaired.

Intangible Assets

Intangible assets with indefinite lives include certain trademarks and tradenames. Indefinite-lived intangible assets are tested for impairment annually on the last day of fiscal November, or more frequently if events or circumstances indicated that the carrying value may exceed the fair value. An impairment loss is recognized when the estimate of discounted future cash flows generated by such assets is less than the carrying amount. Measurement of the impairment loss is based on the fair value of the asset, determined using discounted cash flows. We performed a qualitative impairment test during the fourth quarter of 2023 and determined that indefinite-lived intangible assets were not impaired.

46

MASONITE INTERNATIONAL CORPORATION

Income Taxes

As a multinational corporation, we are subject to taxation in many jurisdictions and the calculation of our tax liabilities involves dealing with inherent uncertainties in the application of complex tax laws and regulations in various taxing jurisdictions. We assess the income tax positions and record tax liabilities for all years subject to examination based upon our evaluation of the facts, circumstances and information available as of the reporting date.

We account for income taxes using the asset and liability method. Under this method, deferred tax assets and liabilities are recognized for the future tax consequences of temporary differences between the carrying amounts and the tax basis of assets and liabilities at enacted rates. We base our estimate of deferred tax assets and liabilities on current tax laws and rates and, in certain cases, business plans and other expectations about future outcomes. We record a valuation allowance to reduce our deferred tax assets to the amount that is more likely than not to be realized. While we have considered future taxable income and ongoing prudent and feasible tax planning strategies in assessing the need for the valuation allowance, in the event that we were to determine that we would be able to realize our deferred tax assets in the future in excess of our net recorded amount, an adjustment to the deferred tax assets would be a credit to income in the period such determination was made. The consolidated financial statements include changes to the valuation allowances as a result of uncertainty regarding our ability to realize certain deferred tax assets in the future.

Our accounting for deferred tax consequences represents our best estimate of future events that can be appropriately reflected in the accounting estimates. Changes in existing tax laws, regulations, rates and future operating results may affect the amount of deferred tax liabilities or the valuation of deferred tax assets over time. The application of tax laws and regulations is subject to legal and factual interpretation, judgment and uncertainty. Tax laws and regulations themselves are also subject to change as a result in changes in fiscal policy, changes in legislation, the evolution of regulations and court rulings.

Although we believe the measurement of liabilities for uncertain tax positions is reasonable, no assurance can be given that the final outcomes of these matters will not be different than what is reflected in the historical income tax provisions and accruals. If we ultimately determine that the payment of these liabilities will be unnecessary, the liability is reversed, and a tax benefit is recognized in the period in which such determination is made. Conversely, additional tax charges are recorded in a period in which it is determined that a recorded tax liability is less than the ultimate assessment is expected to be. If additional taxes are assessed as a result of an audit or litigation, there could be a material effect on our income tax provision and net income in the period or periods for which that determination is made.

Changes in Accounting Standards and Policies

Changes in accounting standards and policies are discussed in Note 1. Business Overview and Significant Accounting Policies in the Notes to the Consolidated Financial Statements in this Annual Report.

Item 7A. Quantitative and Qualitative Disclosures about Market Risk

We are exposed to market risk from changes in foreign currency exchange rates, interest rates and commodity prices, which can affect our operating results and overall financial condition. We manage exposure to these risks through our operating and financing activities and, when deemed appropriate, through the use of derivative financial instruments. Derivative financial instruments are viewed as risk management tools and are not used for speculation or for trading purposes. Derivative financial instruments are generally contracted with a diversified group of investment grade counterparties to reduce exposure to nonperformance on such instruments.

We have in place an enterprise risk management process that involves systematic risk identification and mitigation covering the categories of enterprise, strategic, financial, operation and compliance and reporting risk. The enterprise risk management process receives Board of Directors and Management oversight, drives risk mitigation decision-making and is fully integrated into our internal audit planning and execution cycle.

Foreign Exchange Rate Risk

We have foreign currency exposures related to buying, selling and financing in currencies other than the local currencies in which we operate. In the years ended December 31, 2023, January 1, 2023, and January 2, 2022, approximately 21%, 26% and 32% of our net sales were generated outside of the United States, respectively. We also

47

have substantial assets outside the United States. As a result, the volatility in the price of the U.S. dollar has exposed, and in the future may continue to expose, us to currency exchange risks. Also, since our financial statements are denominated in U.S. dollars, changes in currency exchange rates between the U.S. dollar and other currencies have had, and will continue to have, an impact on many aspects of our financial results. Changes in currency exchange rates for any country in which we operate may require us to raise the prices of our products in that country or allow our competitors to sell their products at lower prices in that country. Unrealized exchange gains and losses arising from the translation of the financial statements of our non-U.S. functional currency operations are accumulated in the cumulative translation adjustments account in accumulated other comprehensive loss. Net gains from currency translation adjustments as a result of translating our foreign assets and liabilities into U.S. dollars during the year ended December 31, 2023, were $19.1 million, which were primarily driven by strengthening of the Pound Sterling, the Canadian Dollar, the Mexican Peso, and the Euro in comparison to the U.S. dollar during the period.

When deemed appropriate, we enter into various derivative financial instruments to preserve the carrying amount of foreign currency-denominated assets, liabilities, commitments and certain anticipated foreign currency transactions. If not mitigated by derivative financial instruments, price increases or other methods, a hypothetical 10% strengthening of the U.S. dollar against all foreign currencies in the jurisdictions in which we operate would result in an approximate $53.9 million translational decrease in our net sales and an approximate $0.2 million translational increase in our net income.

Interest Rate Risk

We are subject to market risk from exposure to changes in interest rates with respect to borrowings under our Term Loan Facility and ABL Facility to the extent they are drawn on and due to our other financing, investing and cash management activities. As of December 31, 2023, and January 1, 2023, there were no outstanding borrowings under our Term Loan Facility or ABL Facility. On October 18, 2023, we borrowed $85.0 million under our ABL Facility in connection with the consummation of the Fleetwood acquisition. On January 3, 2023, we borrowed $250.0 million under our Term Loan Facility and $100.0 million under our ABL Facility in connection with the consummation of the Endura acquisition. As of December 31, 2023, we have repaid all amounts outstanding under the ABL Facility. A 100 basis point increase in the variable interest rate component of our borrowings as of February 2, 2024, would increase our annual interest expense by approximately $2.5 million.

Impact of Inflation, Deflation and Changing Prices

We have experienced inflation and deflation related to our purchase of certain commodity products. We believe that volatile prices for commodities have impacted our net sales and results of operations. We maintain strategies to mitigate the impact of higher raw material, energy and commodity costs, which include cost reduction, sourcing and other actions, which typically offset only a portion of the adverse impact. Inflation and deflation related to our purchases of certain commodity products could have an adverse impact on our operating results in the future. A hypothetical 10% inflationary increase in our material cost of goods sold would result in approximately $195.1 million of increased consolidated cost of goods sold. Additionally, anti-dumping and countervailing duty trade cases, such as the January 8, 2020, Coalition of American Millwork Producers anti-dumping and countervailing duty petitions against Wood Mouldings and Millwork Products from Brazil and China, has had, and is expected to continue to have, an impact on our business and results of operations.

To the Shareholders and the Board of Directors of Masonite International Corporation

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheets of Masonite International Corporation (the Company) as of December 31, 2023 and January 1, 2023, the related consolidated statements of income and comprehensive income, changes in equity and cash flows for each of the three years in the period ended December 31, 2023, and the related notes (collectively referred to as the “consolidated financial statements”). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company at December 31, 2023 and January 1, 2023, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2023, in conformity with U.S. generally accepted accounting principles.

We also have 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, 2023, based on criteria established in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework), and our report dated February 29, 2024 expressed an adverse opinion thereon.

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. 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 Matters

The critical audit matters communicated below are matters arising from the current period audit of the financial statements that were communicated or required to be communicated to the audit committee and that: (1) relate 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 consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matters below, providing separate opinions on the critical audit matters or on the accounts or disclosures to which they relate.

Valuation of Customer Relationships related to the Acquisitions of EPI Holdings, Inc. and Fleetwood Aluminum Products, LLC

Description of the Matter

As described in Note 2 to the consolidated financial statements, on January 3, 2023, the Company completed the acquisition of EPI Holdings, Inc. (Endura) and on October 19, 2023, the Company completed the acquisition of Fleetwood Aluminum Products, LLC (Fleetwood). The Company’s accounting for the acquisitions included determining the fair value of the intangible assets acquired, which included customer relationships of $108.6 million and $112.1 million for Endura and Fleetwood, respectively. Auditing the Company’s valuation of customer relationships was complex due to the significant estimation uncertainty in determining the fair value of customer relationships. The significant estimation uncertainty was primarily due to the sensitivity of the fair value to the underlying significant assumptions including forecasted net sales growth rates for Endura, and EBITDA margins, customer attrition rates and discount rates for Endura and Fleetwood. These significant assumptions are forward looking and could be affected by future market or economic conditions, including industry and company-specific factors.

How We Addressed the Matter in Our Audit

To test the estimated fair value of the customer relationships, we performed audit procedures that included, among others, evaluating the valuation methodology and testing the significant assumptions used in the valuations. For example, we compared the significant assumptions used by the Company to current industry and economic trends, and to historical results of the acquired business. We performed sensitivity analyses of the significant assumptions to evaluate the changes in the fair value of customer relationships that would result from changes in the assumptions. In addition, we involved our valuation specialists to assist in our evaluation of the Company’s valuation methodology and significant assumptions.

51

Valuation of Goodwill related to the Europe Reporting Unit

Description of the Matter

As discussed in Notes 1, 7, and 14 to the consolidated financial statements, the Company’s goodwill is assigned to its reporting units as of the acquisition date and is tested for impairment at the reporting unit level at least annually or whenever changes in circumstances may indicate the carrying amounts may not be recoverable. During the fourth quarter of 2023, the Company performed its annual impairment test, concluded that the Europe reporting unit was impaired, and recorded a goodwill impairment charge of $33.1 million. Auditing management’s annual goodwill impairment test for the Europe reporting unit was complex and judgmental due to the significant estimation uncertainty in determining the fair value of the Europe reporting unit. In particular, the fair value estimate was sensitive to significant assumptions such as net sales growth rates, EBITDA margins and the discount rate. These significant assumptions are forward looking and could be affected by future market or economic conditions, including industry and company-specific factors.

How We Addressed the Matter in Our Audit

We obtained an understanding, evaluated the design, and tested the operating effectiveness of controls over the Company’s goodwill impairment review process, including management’s review of the valuation model and the significant assumptions used in the valuation. To test the estimated fair value of the Company’s Europe reporting unit, we performed audit procedures that included, among others, evaluating the valuation methodologies and testing the significant assumptions used in the valuation. For example, we compared the significant assumptions used by the Company to current industry and economic trends, the Company’s historical results and other guideline companies within the same industry. We performed sensitivity analyses of the significant assumptions to evaluate the changes in the fair value of the reporting unit that would result from changes in the assumptions. In addition, we involved our valuation specialists to assist in our evaluation of the Company’s valuation methodologies and significant assumptions.

MASONITE INTERNATIONAL CORPORATION

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS

1. Business Overview and Significant Accounting Policies

Unless we state otherwise or the context otherwise requires, references to "Masonite," "we," "our," "us" and the "Company" in these notes to the consolidated financial statements refer to Masonite International Corporation and its subsidiaries.

Description of Business

Masonite International Corporation is one of the largest manufacturers of doors in the world, with significant market share in both interior and exterior door products. Masonite operates 64 manufacturing locations in seven countries and sells doors to customers throughout the world, including the United States, Canada and the United Kingdom.

Our workforce includes over 10,000 employees and contract personnel in seven different countries. This includes approximately 2,200 unionized employees, approximately 85% of whom are located in North America and with the remainder in various foreign locations. Nine of our North American facilities have individual collective bargaining agreements, which are negotiated locally and the terms of which vary by location.

Basis of Presentation

We prepare these consolidated financial statements in accordance with accounting principles generally accepted in the United States of America ("GAAP"). These consolidated financial statements include the accounts of Masonite International Corporation, a company incorporated under the laws of British Columbia, and its subsidiaries, as of December 31, 2023, and January 1, 2023, and for the years ended December 31, 2023, January 1, 2023, and January 2, 2022.

Our fiscal year is the 52- or 53-week period ending on the Sunday closest to December 31. In a 52-week year, each fiscal quarter consists of 13 weeks. For ease of disclosure, the 13-week periods are referred to as three-month periods and the 52- or 53-week periods are referred to as years. Our 2020 fiscal year, which ended on January 3, 2021, contained 53 weeks of operating results, with the additional week occurring in the fourth quarter.

Changes in Accounting Standards and Policies

Adoption of Recent Accounting Pronouncements

In December 2021, the Financial Accounting Standards Board ("FASB") issued ASU 2021-10, "Government Assistance," which requires annual disclosures that increase the transparency of transactions involving government grants, including (1) the types of transactions, (2) the accounting for those transactions and (3) the effect of those transactions on an entity's financial statements. The guidance was effective for annual periods beginning after December 15, 2021, with early adoption permitted. We have adopted the new guidance as of January 3, 2022, the beginning of fiscal year 2022, and the adoption did not have a material impact on our financial statements or disclosures.

In October 2021, the FASB issued ASU 2021-08, "Accounting for Contract Assets and Contract Liabilities from Contracts with Customers," which clarifies that an acquirer of a business should recognize and measure contract assets and contract liabilities in a business combination in accordance with ASU 2014-09," Revenue from Contracts with Customers" as if the entity had originated the contracts. The guidance was effective for fiscal years beginning after December 15, 2022, with early application permitted. We have adopted the new guidance as of January 2, 2023, the beginning of fiscal year 2023, and the adoption did not have a material impact on our financial statements or disclosures.

Other Recent Accounting Pronouncements not yet Adopted

In December 2023, the FASB issued ASU 2023-09, "Income Taxes (Topic 740) - Improvements to Income Tax Disclosures," which requires public business entities to annually disclose specific categories in the rate reconciliation and provide additional information for reconciling items that meet a quantitative threshold. The guidance is effective for fiscal years beginning after December 15, 2024, with early application permitted. We did not early adopt and believe the adoption of this new guidance will not have a material impact on our financial statements.

57

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS (continued)

In November 2023, the FASB issued ASU 2023-07, "Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures," which improves reportable segment disclosure requirements, primarily through enhanced disclosures about significant segment expenses. The guidance is effective for fiscal years beginning after December 15, 2023, with early application permitted. We did not early adopt and believe the adoption of this new guidance will not have a material impact on our financial statements.

Summary of Significant Accounting Policies

(a) Principles of consolidation:

These consolidated financial statements include the accounts of Masonite and our subsidiaries and the accounts of any variable interest entities for which we are the primary beneficiary. Intercompany accounts and transactions have been eliminated upon consolidation. The results of subsidiaries acquired during the periods presented are consolidated from their respective dates of acquisition using the acquisition method. Subsidiaries are prospectively deconsolidated as of the date we no longer have effective control of the entity.

(b) Translation of consolidated financial statements into U.S. dollars:

These consolidated financial statements are expressed in U.S. dollars. The accounts of the majority of our self-sustaining foreign operations are maintained in functional currencies other than the U.S. dollar. Assets and liabilities for these subsidiaries have been translated into U.S. dollars at the exchange rates prevailing at the end of the period and results of operations at the average exchange rates for the period. Unrealized exchange gains and losses arising from the translation of the financial statements of our non-U.S. functional currency operations are accumulated in the cumulative translation adjustments account in accumulated other comprehensive loss. For our foreign subsidiaries where the U.S. dollar is the functional currency, all foreign currency-denominated accounts are remeasured into U.S. dollars. Unrealized exchange gains and losses arising from remeasurements of foreign currency-denominated assets and liabilities are included within other (income) expense, net in the consolidated statements of income and comprehensive income. Gains and losses arising from international intercompany transactions that are of a long-term investment nature are reported in the same manner as translation gains and losses. Realized exchange gains and losses are included in net income for the periods presented.

(c) Cash and cash equivalents:

Cash includes cash equivalents which are short-term highly liquid investments with original maturities of three months or less.

(d) Restricted cash:

Restricted cash includes cash we have placed as collateral for standby letters of credit. The letters of credit guarantee payment to third parties in the event the company is in breach of contract terms as detailed in each letter of credit. As of December 31, 2023, and January 1, 2023, we had standby letters of credit totaling $2.0 million and $2.1 million, respectively. There were no amounts drawn upon these letters of credit as of December 31, 2023, or January 1, 2023.

(e) Accounts receivable:

Our customers are primarily retailers, distributors and contractors. We record an allowance for credit losses at the time that accounts receivable are initially recorded based on the historical write-off experience and the current economic environment as well as our expectations of future economic conditions. We reassess the allowance at each reporting date. When it becomes apparent, based on age or customer circumstances, that such amounts will not be collected, they are charged to the allowance. Payments subsequently received are credited to the credit loss expense account included within selling, general and administration expenses in the consolidated statements of income and comprehensive income. Generally, we do not require collateral for our accounts receivable.

58

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS (continued)

(f) Inventories:

Raw materials, work in process and finished goods are valued at the lower of cost or net realizable value. Cost is determined on a first in, first out basis. In determining the net realizable value, we consider factors such as yield, turnover, expected future demand and past experience.

The cost of inventories includes all costs of purchase, costs of conversion and other costs incurred in bringing the inventories to their present location and condition. The costs of conversion of inventories include costs directly related to the units of production, such as direct labor. They also include a systematic allocation of fixed and variable production overheads that are incurred in converting raw materials into finished goods. Fixed production overheads are those indirect costs of production that remain relatively constant regardless of the volume of production, such as depreciation and maintenance of factory buildings and equipment, and the cost of factory management and administration. Variable production overheads are those indirect costs of production that vary directly, or nearly directly, with the volume of production, such as indirect materials and indirect labor.

To determine the cost of inventory, we allocate fixed expenses to the cost of production based on the normal capacity, which refers to a range of production levels and is considered the production expected to be achieved over a number of periods or seasons under normal circumstances, taking into account the loss of capacity resulting from planned maintenance. Fixed overhead costs allocated to each unit of production are not increased due to abnormally low production. Those excess costs are recognized as a current period expense. When a production facility is completely shut down temporarily, it is considered idle, and all related expenses are charged to cost of goods sold.

(g) Property, plant and equipment:

Property, plant and equipment are stated at cost. Depreciation is recorded based on the carrying values of buildings, machinery and equipment using the straight-line method over the estimated useful lives set forth as follows:

	Useful Life (Years)
Buildings	20 - 40
Machinery and equipment
Tooling	10 - 25
Machinery and equipment	5 - 25
Molds and dies	20 - 25
Office equipment, fixtures and fittings	3 - 10
Information technology systems	5 - 15

Improvements and major maintenance that extend the life of an asset are capitalized; other repairs and maintenance are expensed as incurred. When assets are retired or otherwise disposed, their carrying values and accumulated depreciation are removed from the accounts.

Property, plant and equipment are tested for impairment when events or changes in circumstances indicate that the carrying value of an asset or asset group may not be recoverable. An impairment loss is recognized when the carrying amount of an asset or asset group being tested for recoverability exceeds the sum of the undiscounted cash flows expected from its use and disposal. Impairments are measured as the amount by which the carrying amount of the asset or asset group exceeds its fair value, as determined using a discounted cash flows approach when quoted market prices are not available.

(h) Leases:

We determine if a contract is a lease at inception or upon acquisition and reevaluate each time a lease contract is amended or otherwise modified. A lease will be classified as an operating lease if it does not meet any of the criteria for a finance lease. Those criteria include the transfer of ownership of the underlying asset by the end of the lease term; an option to purchase the underlying asset that we would be reasonably certain to exercise; the lease term is for the major part of the remaining economic life of the underlying asset; the present value of the sum of the lease payments and any

59

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS (continued)

residual value guaranteed by us that is not already reflected in the lease payments equals or exceeds substantially all of the fair value of the underlying asset or if the underlying asset is of such a specialized nature that it is expected to have no alternative use to the lessor at the end of the lease term.

The assets and liabilities relating to operating leases are included in operating lease right-of-use assets, accrued expenses, and long-term operating lease liabilities in our consolidated balance sheets. The assets and liabilities relating to finance leases are included in property, plant and equipment, net, accrued expenses and other liabilities in our consolidated balance sheets.

ROU assets represent our right to use an underlying asset for the lease term and lease liabilities represent our obligation to make lease payments arising from the lease. Operating lease ROU assets and liabilities are recognized at the respective lease commencement date based on the present value of lease payments over the expected lease term. Since our leases do not specify implicit discount rates, we use our incremental borrowing rate based on the information available at the commencement date in determining the present value of lease payments. The operating lease ROU asset also includes any initial direct costs and is adjusted for lease incentives and prepaid or accrued rent. The lease term begins on the date when the lessor makes the underlying asset available for use to us, and our expected lease terms include options to extend the lease when it is reasonably certain that we will exercise those options. Lease payments are recognized in the consolidated statements of income and comprehensive income on a straight-line basis over the expected lease term.

Leases with an initial term of 12 months or less are not recorded on the balance sheet, with the related lease expense recognized on a straight-line basis over the lease term. Lease and non-lease components of a contract are combined into a single lease component for accounting purposes.

Our operating leases include leases for real estate (including manufacturing sites, warehouses and offices) and machinery and equipment and our finance leases include leases for real estate. We have no material subleases. Certain of our operating leases contain provisions for renewal ranging from one to four options of one to ten years each.    

(i) Goodwill:

We use the acquisition method of accounting for all business combinations, and we evaluate all business combinations for intangible assets that should be recognized apart from goodwill. Goodwill adjustments are recorded for the effect on goodwill of changes to net assets acquired during the measurement period (up to one year from the date of acquisition) for 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.

Goodwill is not amortized, but instead is tested annually for impairment on the last day of fiscal November, or more frequently if events or changes in circumstances indicate the carrying amount may not be recoverable. The test for impairment is performed at the reporting unit level by comparing the reporting unit’s carrying amount to its fair value. Possible impairment in goodwill is first analyzed using qualitative factors such as macroeconomic and market conditions, changing costs and actual and projected performance, amongst others, to determine whether it is more likely than not that the book value of the reporting unit exceeds its fair value. If it is determined more likely than not that the book value exceeds fair value, a quantitative analysis is performed to test for impairment. When quantitative steps are determined necessary, the fair values of the reporting units are estimated through the use of discounted cash flow analysis and market multiples. If the carrying amount exceeds fair value, then goodwill is impaired. Any impairment in goodwill is measured as the excess of the carrying value of goodwill over the fair value.

When developing our discounted cash flow analyses, a number of assumptions and estimates are involved to forecast operating cash flows, including future net sales growth, EBITDA margin, benefits from restructuring initiatives, income tax rates, capital spending, business initiatives and working capital changes. These assumptions may vary significantly among the reporting units. Operating cash flow forecasts are based on operating plans for the early years and historical relationships and long-term economic outlooks for our industry in later years. The discount rate is estimated for each specific reporting unit. Due to the many variables inherent in the estimation of a reporting unit’s fair value and the relative size of our recorded goodwill, differences in assumptions may have a material effect on the results of our impairment analyses. In the year ended December 31, 2023, we recorded $33.1 million in goodwill impairment charges in our Europe reporting unit. There were no impairment charges recorded against goodwill in 2022. In 2021, we

60

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS (continued)

recorded $59.5 million in impairment charges related to the Architectural reporting unit. See Note 14 for further information.

(j) Intangible assets:

Intangible assets with definite lives include customer relationships, patents, system software development and acquired trademarks and tradenames. Definite lived intangible assets are amortized over their estimated useful lives. Information pertaining to the estimated useful lives of intangible assets is as follows:

	Estimated Useful Life (Years)	Estimated Useful Life
Customer relationships	10 - 15	Over expected relationship period
Patents	10 - 12	Over expected useful life
System software development	5 - 15	Over expected useful life
Acquired trademarks and tradenames	2 - 10	Over expected useful life

Amortizable intangible assets are tested for impairment whenever events or changes in circumstances indicate that the carrying value may be greater than fair value. An impairment loss is recognized when the estimate of undiscounted future cash flows generated by such assets is less than the carrying amount. Measurement of the impairment loss is based on the fair value of the asset. Fair value is measured using discounted cash flows.

Indefinite lived intangible assets are not amortized, but instead are tested for impairment annually on the last day of fiscal November, or more frequently if events or circumstances indicate the carrying value may exceed the fair value.

(k) Income taxes:

As a multinational corporation, we are subject to taxation in many jurisdictions and the calculation of our tax liabilities involves dealing with inherent uncertainties in the application of complex tax laws and regulations in various taxing jurisdictions. We assess the income tax positions and record tax liabilities for all years subject to examination based upon our evaluation of the facts, circumstances and information available as of the reporting date. Our global structure required an assessment of the Company’s interpretation and application of tax laws in multiple jurisdictions including the income tax impact of the legal entity ownership structure and intercompany transactions.

We use the asset and liability method of accounting for income taxes. Under the asset and liability method, deferred tax assets and liabilities are recognized for the deferred tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities due to a change in tax rates is recognized in income in the period that includes the date of enactment. A valuation allowance is recorded to reduce deferred tax assets to an amount that is anticipated to be realized on a more likely than not basis.

We account for uncertain taxes in accordance with ASC 740, "Income Taxes." The initial benefit recognition model follows a two-step approach. First, we evaluate if the tax position is more likely than not of being sustained if audited based solely on the technical merits of the position. Second, we measure the appropriate amount of benefit to recognize. This is calculated as the largest amount of tax benefit that has a greater than 50% likelihood of ultimately being realized upon settlement. Subsequently at each reporting date, the largest amount that has a greater than 50% likelihood of ultimately being realized, based on information available at that date, will be measured and recognized.

We recognize interest and penalties related to unrecognized tax benefits within the income tax expense line in the consolidated statements of income and comprehensive income. Accrued interest and penalties are included within the related tax liability line in the consolidated balance sheets.

61

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS (continued)

(l) Employee future benefits:

We maintain defined benefit pension plans. Benefits under the plans were frozen or curtailed at various times in the past. Earnings are charged with the cost of benefits earned by employees as services are rendered. The cost reflects management’s best estimates of the pension plans’ expected investment yields, wage and salary escalation, mortality of members, terminations and the ages at which members will retire. Changes in these assumptions could impact future pension expense. Service cost components are recognized within cost of goods sold and non-service cost components are recognized within other (income) expense, net in the consolidated statements of income and comprehensive income. The excess of the net actuarial gain (loss) over 10% of the greater of the benefit obligation or fair value of plan assets at the beginning of the year is amortized over the average remaining service lives of the members.

Assets are valued at fair value for the purpose of calculating the expected return on plan assets. Past service costs arising from plan amendments are amortized on a straight-line basis over the average remaining service period of employees active at the date of amendment.

When a restructuring of a benefit plan gives rise to both a curtailment and a settlement of obligations, the curtailment is accounted for prior to the settlement. Curtailment gains are offset against unrecognized losses and any excess gains and all curtailment losses are recorded in the period in which the curtailment occurs.

(m) Restructuring costs:

Restructuring costs include all salary-related severance benefits that are accrued and expensed when a restructuring plan has been put into place, the plan has received approval from the appropriate level of management and the benefit is probable and reasonably estimable. In addition to salary-related costs, we incur other restructuring costs when facilities are closed or capacity is realigned within the organization. Upon termination of a contract we record liabilities and expenses pursuant to the terms of the relevant agreement. For non-contractual restructuring activities, liabilities and expenses are measured and recorded at fair value in the period in which they are incurred.

Restructuring-related costs are presented separately in the consolidated statements of income and comprehensive income whereas non-restructuring severance benefits are charged to cost of goods sold or selling, general and administration expense depending on the nature of the job responsibilities.

(n) Financial instruments:

We have applied a framework consistent with ASC 820, "Fair Value Measurement and Disclosure," and have disclosed all financial assets and liabilities measured at fair value and non-financial assets and liabilities measured at fair value on a non-recurring basis (at least annually).

We classify and disclose assets and liabilities carried at fair value in one of the following three categories:

        Level 1: Quoted market prices in active markets for identical assets or liabilities.

        Level 2: Observable market based inputs or unobservable inputs that are corroborated by market data.

        Level 3: Unobservable inputs that are not corroborated by market data.

The estimated fair value of a financial instrument is the amount at which the instrument could be exchanged in a current transaction between willing parties, other than a forced or liquidation sale. These estimates, although based on the relevant market information about the financial instrument, are subjective in nature and, therefore, cannot be determined with precision. Changes in assumptions could significantly affect the estimates.

(o) Share based compensation expense:

We have a share based compensation plan, which is described in detail in Note 12. We apply the fair value method of accounting using comprehensive valuation models, including the Black-Scholes-Merton option pricing model and the Monte Carlo simulation method, to determine the compensation expense.

62

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS (continued)

(p) Revenue recognition:

Revenue from the sale of products is recognized when control of the promised goods is transferred to our customers based on the agreed-upon shipping terms, in an amount that reflects the consideration to which we expect to be entitled in exchange for those goods or services. Volume rebates, expected returns, discounts and other incentives to customers are considered variable consideration and we estimate these amounts based on the expected amount to be provided to customers and reduce the revenues we recognize accordingly. Sales taxes and value added taxes assessed by governmental entities are excluded from the measurement of consideration expected to be received. Shipping and handling costs incurred after a customer has taken possession of our goods are treated as a fulfillment cost and are not considered a separate performance obligation. Shipping and other transportation costs charged to customers are recorded in both revenues and cost of goods sold in the consolidated statements of income and comprehensive income.

(q) Product warranties:

We warrant certain qualitative attributes of our door products. We have recorded provisions for estimated warranty and related costs within accrued expenses on the consolidated balance sheets, based on historical experience and we periodically adjust these provisions to reflect actual experience. The rollforward of our warranty provision is as follows for the periods indicated:

	Year Ended
(In thousands)	December 31, 2023		January 1, 2023		January 2, 2022
Balance at beginning of period	$	3,881	$	4,015	$	4,635
Additions charged to expense	4,792		5,085		4,646
Deductions	(4,436)		(5,219)		(5,266)
Balance at end of period	$	4,237	$	3,881	$	4,015

(r) Vendor rebates:

We account for cash consideration received from a vendor as a reduction of cost of goods sold and inventory, in the consolidated statements of income and comprehensive income and consolidated balance sheets, respectively. The cash consideration received represents agreed-upon vendor rebates that are earned in the normal course of operations.

(s) Advertising costs:

We recognize advertising costs as they are incurred. Advertising costs incurred primarily relate to tradeshows and are included within selling, general and administration expense in the consolidated statements of income and comprehensive income. Advertising costs were $20.0 million, $16.9 million and $14.2 million in the years ended December 31, 2023, January 1, 2023, and January 2, 2022, respectively.

(t) Research and development costs:

We recognize research and development costs as they are incurred. Research and development costs incurred primarily relate to the development of new products and the improvement of manufacturing processes, and are primarily included within cost of goods sold in the consolidated statements of income and comprehensive income. These costs exclude the significant investments in other areas such as advanced automation. Research and development costs were $27.8 million, $21.2 million and $18.4 million in the years ended December 31, 2023, January 1, 2023, and January 2, 2022, respectively.

(u) Insurance losses and proceeds:

All involuntary conversions of property, plant and equipment are recorded as losses within loss (gain) on disposal of property, plant and equipment, which is included within selling, general and administration expense in the consolidated statements of income and comprehensive income and as reductions to property, plant and equipment in the consolidated balance sheets. Any subsequent proceeds received for insured losses of property, plant and equipment are also recorded as gains within loss (gain) on disposal of property, plant and equipment, and are classified as cash flows

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS (continued)

from investing activities in the consolidated statements of cash flows in the period in which the cash is received. Proceeds received for business interruption recoveries are recorded as a reduction to selling, general and administration expense in the consolidated statements of income and comprehensive income and are classified as cash flows from operating activities in the consolidated statements of cash flows in the period in which an acknowledgment from the insurance carrier of settlement or partial settlement of a non-refundable nature has been presented to us.

(v) Equity investments:

We account for investments in affiliates of between 20% and 50% ownership, over which we have significant influence, using the equity method. We record our share of earnings of the affiliate within other income, net of expense, in the consolidated statements of income and comprehensive income and dividends as a reduction of the investment in the affiliate in the consolidated balance sheets when declared.

(w) Segment reporting:

Our reportable segments are organized and managed principally by end market: North American Residential, Europe and Architectural. The Corporate & Other category includes unallocated corporate costs and the results of immaterial operating segments that were not aggregated into any reportable segment. In addition to similar economic characteristics we also consider the following factors in determining the reportable segments: the nature of business activities, the management structure directly accountable to our chief operating decision maker for operating and administrative activities, availability of discrete financial information and information presented to the Board of Directors and investors.

(x) Use of estimates:

The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions which affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of the date of the consolidated financial statements and the reported amounts of net sales and expenses during the reporting periods. During 2023, there were no material changes in the methods or policies used to establish estimates and assumptions. Actual results may differ from our estimates.

2. Acquisitions and Divestitures

Acquisitions

Fleetwood

On October 19, 2023, the Company completed the acquisition of all of the issued and outstanding limited liability company interests of Fleetwood Aluminum Products, LLC (“Fleetwood”). The total consideration for this acquisition amounted to approximately $279.1 million, inclusive of $26.2 million designated for potential purchase price adjustments and indemnification claims and which is currently held in an escrow account controlled by a third party. The total consideration was funded with a combination of cash on hand and borrowings under the ABL Facility. Fleetwood is a leading designer and manufacturer of premium, aluminum-framed glass door and window solutions for luxury homes. Their products include multi-slide and pocket glass patio doors, pivot and hinged glass entry doors and folding glass door wall systems, as well as accompanying premium window products. The acquisition aligns with the Doors That Do MoreTM strategy focused on bringing differentiated door systems to the residential market.

The Company has accounted for the acquisition as a business combination and allocated the preliminary estimated purchase price to the estimated fair values of assets acquired and liabilities assumed utilizing various valuation methods including replacement cost, market values and the income approach. The Company has not yet completed its evaluation and determination of the value of certain assets acquired and liabilities assumed, primarily involving (i) certain historical information used in the final valuation of intangible assets, and (ii) the final assessment and valuation of inventory and deferred income taxes, which could impact goodwill during the measurement period. The $73.5 million excess purchase price over the fair value of tangible and intangible assets acquired was allocated to goodwill. Goodwill represents the estimated future economic benefits arising from other assets acquired that could not be individually identified and separately recognized, such as the delivery of luxury products, which supports our Doors That Do MoreTM strategy. This goodwill is deductible for tax purposes and relates to the North American Residential segment.

The fair values of intangible assets acquired are based on management's estimates and assumptions including the income approach, the cost approach and the market approach. Customer relationships and patents acquired are not expected to have any residual value. The gross contractual value of acquired trade receivables was $5.6 million.

Endura

On January 3, 2023, we completed the acquisition of 100% of the outstanding equity of EPI Holdings, Inc. ("Endura"), for total consideration of approximately $403.3 million, including an $18.0 million holdback which is payable 24 months after the acquisition date and was recorded in the consolidated balance sheets as a component of other liabilities. The total consideration was funded with borrowings under our Term Loan Facility and ABL Facility. Endura is a leading innovator and manufacturer of high-performance door frames and door system components in the United States. Endura’s product offerings include engineered frames, self-adjusting sill systems, weather sealing, multi-point locks and installation accessories used by builders and contractors in residential new construction as well as repair and remodeling applications. The acquisition is intended to accelerate our Doors That Do MoreTM strategy and maximize our growth potential. The $181.2 million excess purchase price over the fair value of tangible and intangible assets acquired was allocated to goodwill. The goodwill principally represents anticipated synergies to be gained from the integration into our existing business and acquisition of the assembled workforce. This goodwill is not deductible for tax purposes and relates to the North American Residential segment.

The Company has accounted for the acquisition as a business combination and allocated the estimated purchase price to the estimated fair values of assets acquired and liabilities assumed utilizing various valuation methods including replacement cost, market values and the income approach.

Pro Forma Information

The following unaudited pro forma financial information represents the consolidated financial information as if the acquisitions had been included in our consolidated results beginning on the first day of the fiscal year prior to the respective acquisition dates. The pro forma results have been calculated after adjusting the results of the acquired entities to remove intercompany transactions and to reflect the additional depreciation, amortization and interest expense that would have been charged assuming the fair value adjustments to property, plant and equipment and intangible assets and the additional debt incurred to fund the acquisition had been applied on the first day of the fiscal year prior to the respective acquisition date, together with the consequential tax effects. The pro forma results do not reflect any cost savings, operating synergies or revenue enhancements that the combined companies may achieve as a result of the acquisition; the costs to combine the companies' operations; or the costs necessary to achieve these costs savings, operating synergies and revenue enhancements. As a result, the pro forma information below does not purport to represent actual results had the acquisition been consummated on the date indicated and it is not necessarily indicative of future results of operations.

Divestitures

As previously disclosed, we are actively reviewing strategic alternatives for our Architectural segment, including a potential sale of some or all of the business. There can be no assurance that a potential transaction will be consummated or on what terms. The Arrangement Agreement with Owens Corning restricts our ability to dispose of certain businesses, properties or assets of the Company without Owens Corning’s prior consent. If a transaction is

67

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS (continued)

consummated, depending on the sale price, we could incur an impairment charge related to the book value of the segment's assets. This charge could be material.

During the fourth quarter of 2022, we completed the liquidation of our legal entity in Turkey. As a result, we recognized $0.9 million in loss on disposal of subsidiaries. The total charge consists of $0.7 million relating to the recognition of cumulative translation adjustment out of accumulated other comprehensive loss and $0.2 million relating to the write-off of net assets.

On June 14, 2021, we completed the sale of all the capital stock of our Czech business for consideration of $7.0 million, net of cash disposed. The divestiture of this business resulted in a loss on disposal of subsidiaries of $8.6 million, which was recognized in the second quarter of 2021 in the Europe segment. The total charge consisted of $5.1 million relating to the write-off of the net assets sold and other professional fees and $3.5 million relating to the recognition of the cumulative translation adjustment out of accumulated other comprehensive loss.

3. Accounts Receivable

Our customers consist mainly of retailers, distributors and contractors. Our ten largest customers accounted for 65.2% and 62.3% of total accounts receivable as of December 31, 2023, and January 1, 2023, respectively. Our largest customer, The Home Depot, Inc. accounted for more than 10% of the consolidated gross accounts receivable balance as of December 31, 2023, and January 1, 2023. In addition, Lowe's Companies, Inc. accounted for more than 10% of the consolidated gross accounts receivable balance as of December 31, 2023. No other individual customer accounted for greater than 10% of the consolidated gross accounts receivable balance at either December 31, 2023, or January 1, 2023.

The changes in the allowance for doubtful accounts were as follows for the periods indicated:

Deductions	(428)		(669)		(964)
Balance at end of period	$	3,077	$	2,480	$	2,087

We maintain an accounts receivable sales program with a third party (the "AR Sales Program"). Under the AR Sales Program, we can transfer ownership of eligible trade accounts receivable of certain customers. Receivables are sold outright to a third party who assumes the full risk of collection, without recourse to us in the event of a loss. Transfers of receivables under this AR Sales Program are accounted for as sales. Proceeds from the transfers reflect the face value of the accounts receivable less a discount. Receivables sold under the AR Sales Program are excluded from trade accounts receivable in the consolidated balance sheets and are included in cash flows from operating activities in the consolidated statements of cash flows. The discounts on the sales of trade accounts receivable sold under the AR Sales Program were not material for any of the periods presented and were recorded in selling, general and administration expense within the consolidated statements of income and comprehensive income.

In most countries we pay and collect Value Added Tax ("VAT") when procuring goods and services within the normal course of business. VAT receivables are established in jurisdictions where VAT paid exceeds VAT collected and are recoverable through the filing of refund claims.

Certain wood moldings and millwork products being imported into the U.S. are subject to import tariffs. Tariff deposits are paid to the government and are recoverable through an assessment process.

Within fiscal year 2023, the Company completed the acquisitions of Fleetwood and Endura. As part of these acquisitions, we recognized $254.6 million in combined goodwill. See Note 2. Acquisitions and Divestitures for further information.

We evaluate goodwill and indefinite-lived intangible assets for impairment annually during the fourth quarter and at interim dates if indicators of impairment exist. Goodwill is assessed for impairment at the reporting unit level.

Gross goodwill before cumulative impairment charges and foreign exchange fluctuations in the Europe reporting unit was $60.0 million as of the beginning of 2023. During the year ended December 31, 2023, we recognized an asset impairment charge of $33.2 million related to a goodwill impairment charge due to weakening consumer confidence in the United Kingdom that continues to affect demand in the repair and remodel market, negative impacts from rising energy and fuel costs, partly attributable to geopolitical conflicts, as well as rising costs for raw materials and material supply constraints. The charge represents the amount by which the carrying value of the Europe reporting unit exceeded its fair value, and was recorded in the consolidated statements of income and comprehensive income and reduced the goodwill balance in the Europe reporting unit from $60.0 million to $26.8 million, excluding foreign exchange fluctuations. See Note 14 for further information.

Gross goodwill before cumulative impairment charges in the Architectural reporting unit was $59.5 million as of the beginning of 2021. As a result of manufacturing constraints in the Architectural reporting unit due to COVID-19 related absenteeism, material availability and production challenges, a goodwill impairment charge of $59.5 million was recorded to selling, general and administration expenses in 2021. The charge represents the amount by which the carrying value of the Architectural reporting unit exceeded its fair value and reduced the goodwill balance in the Architectural reporting unit from $59.5 million to zero. See Note 14 for further information.

Debt issuance costs incurred in connection with the 2030 Notes and the 2028 Notes were capitalized as a reduction to the carrying value of debt and are being accreted to interest expense over their respective terms. Additionally, we pay interest on any outstanding principal under our Term Loan Facility and ABL Facility, each as defined below, and we are required to pay a commitment fee for unutilized commitments under the ABL Facility, both of which are recorded in interest expense as incurred.

3.50% Senior Notes due 2030

On July 26, 2021, we issued $375.0 million aggregate principal senior unsecured notes (the "2030 Notes"). The 2030 Notes were issued in a private placement for resale to qualified institutional buyers pursuant to Rule 144A of the Securities Act of 1933, as amended (the "Securities Act"), and to buyers outside of the United States pursuant to Regulation S under the Securities Act. The 2030 Notes bear interest at 3.50% per annum, payable in cash semiannually in arrears on February 15 and August 15 of each year and the principal is due February 15, 2030. The 2030 Notes were issued at par. We received net proceeds of $370.3 million after deducting $4.7 million of debt issuance costs. The debt issuance costs were capitalized as a reduction to the carrying value of debt and are being accreted to interest expense over the term of the 2030 Notes using the effective interest method. The net proceeds from the issuance of the 2030 Notes were used to redeem the remaining $300.0 million aggregate principal amount of the 2026 Notes (as described below), including the payment of related premiums, fees and expenses, with the balance of the proceeds available for general corporate purposes.

Obligations under the 2030 Notes are fully and unconditionally guaranteed, jointly and severally, on a senior unsecured basis, by certain of our directly or indirectly wholly-owned subsidiaries. We may redeem the 2030 Notes, in whole or in part, at any time, at the applicable redemption prices specified under the indenture governing the 2030 Notes, plus accrued and unpaid interest, if any, to the date of redemption. If we experience certain changes of control, we must offer to repurchase all of the 2030 Notes at a purchase price of 101.00% of their principal amount, plus accrued and unpaid interest, if any, to, but excluding, the repurchase date.

The indenture governing the 2030 Notes contains limited covenants that, among other things, limit our ability and the ability of our subsidiaries to (i) incur certain secured debt, (ii) engage in certain sale and leaseback transactions and (iii) merge or consolidate with other entities. The foregoing limitations are subject to exceptions as set forth in the indenture governing the 2030 Notes. The indenture governing the 2030 Notes contains customary events of default (subject to certain cases to customary grace and cure periods). As of December 31, 2023, we were in compliance with all covenants under the indenture governing the 2030 Notes.

5.375% Senior Notes due 2028

On July 25, 2019, we issued $500.0 million aggregate principal senior unsecured notes (the "2028 Notes"). The 2028 Notes were issued in a private placement for resale to qualified institutional buyers pursuant to Rule 144A under the Securities Act, and to buyers outside of the United States pursuant to Regulation S under the Securities Act. The 2028 Notes were issued without registration rights and are not listed on any securities exchange. The 2028 Notes bear interest at 5.375% per annum, payable in cash semiannually in arrears on February 1 and August 1 of each year and the

73

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS (continued)

principal is due February 1, 2028. The 2028 notes were issued at par. We received net proceeds of $493.3 million after deducting $6.7 million of debt issuance costs. The debt issuance costs were capitalized as a reduction to the carrying value of debt and are being accreted to interest expense over the term of the 2028 Notes using the effective interest method. The net proceeds from issuance of the 2028 Notes, together with available cash balances, were used to redeem the remaining $500.0 million aggregate principal amount of similar senior unsecured notes.

Obligations under the 2028 Notes are fully and unconditionally guaranteed, jointly and severally, on a senior unsecured basis, by certain of our directly or indirectly wholly-owned subsidiaries. We may redeem the 2028 Notes, in whole or in part, at any time on or after February 1, 2023, at the applicable redemption prices specified under the indenture governing the 2028 Notes, plus accrued and unpaid interest, if any, to the date of redemption. If we experience certain changes of control or consummate certain asset sales and do not reinvest the net proceeds, we must offer to repurchase all of the 2028 Notes at a purchase price of 101.00% (in the case of changes in control) or 100.00% (in the case of asset sales) of their principal amount, plus accrued and unpaid interest, if any, to, but excluding, the repurchase date.

The indenture governing the 2028 Notes contains restrictive covenants that, among other things, limit our ability and the ability of our subsidiaries to: (i) incur additional debt and issue disqualified or preferred stock, (ii) make restricted payments, (iii) sell assets, (iv) create or permit restrictions on the ability of our restricted subsidiaries to pay dividends or make other distributions to the parent company, (v) create or incur certain liens, (vi) enter into sale and leaseback transactions, (vii) merge or consolidate with other entities and (viii) enter into transactions with affiliates. The foregoing limitations are subject to exceptions as set forth in the indenture governing the 2028 Notes. In addition, if in the future the 2028 Notes have an investment grade rating from at least two nationally recognized statistical rating organizations, certain of these covenants will be terminated. The indenture governing the 2028 Notes contains customary events of default (subject in certain cases to customary grace and cure periods). As of December 31, 2023, we were in compliance with all covenants under the indenture governing the 2028 Notes.

5.750% Senior Notes due 2026

On August 27, 2018, we issued $300.0 million aggregate principal senior unsecured notes (the "2026 Notes"). The 2026 Notes were issued in a private placement for resale to qualified institutional buyers pursuant to Rule 144A under the Securities Act, and to buyers outside of the United States pursuant to Regulation S under the Securities Act. The 2026 Notes were issued without registration rights and are not listed on any securities exchange. The 2026 Notes bore interest at 5.75% per annum, payable in cash semiannually in arrears on March 15 and September 15 of each year and were originally due September 15, 2026. The 2026 notes were issued at par. We received net proceeds of $295.7 million after deducting $4.3 million of debt issuance costs. The debt issuance costs were capitalized as a reduction to the carrying value of debt and were accreted to interest expense over the term of the 2026 Notes using the effective interest method.

Subsequent to the closing of the 2030 Notes offering, the 2026 Notes were redeemed, and the notes were considered extinguished as of July 26, 2021. Under the terms of the indenture governing the 2026 Notes, we paid the applicable premium of $10.8 million. Additionally, the unamortized debt issuance costs of $2.8 million relating to the 2026 Notes were written off in conjunction with the extinguishment of the 2026 Notes. The resulting loss on extinguishment of debt was $13.6 million and was recorded as part of income from continuing operations before income tax expense in the condensed consolidated statements of income and comprehensive income in 2021. Additionally, the cash payment of interest accrued was accelerated to the redemption date.

Term Loan Facility

On December 13, 2022, we and certain of our subsidiaries entered into a new delayed-draw term loan credit agreement (the "Term Loan Credit Agreement") maturing on December 12, 2027 (the "Term Loan Maturity Date"). The Term Loan Credit Agreement provides for a senior secured five-year delayed-draw term loan facility of $250.0 million (the "Term Loan Facility"). Loans under the Term Loan Facility (the "Term Loans") will bear interest at a rate equal to, at our option, (1) the Adjusted Term SOFR Rate (as defined in the Term Loan Credit Agreement) plus an applicable margin of 2.25% or (2) an alternate base rate equal to the greatest of (i) the "Prime Rate" in the U.S. last quoted by The Wall Street Journal, (ii) 0.50% above the greater of the federal funds rate and the rate comprised of both overnight federal funds and overnight eurodollar transactions denominated in Dollars, (iii) 1.00% above the Adjusted Term SOFR

74

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS (continued)

Rate for a one month interest period and (iv) 1.00%, plus, in each case, an applicable margin of 1.25%, subject to, in each of cases (1) and (2), an agreed interest rate floor. The Term Loans are repayable in equal quarterly installments for an annual aggregate amortization payment equal to 15% of the aggregate principal amount of the Term Loans, with the balance of the principal being due on the Term Loan Maturity Date.

The Term Loan Credit Agreement also includes a quarterly ticking fee of 25 basis points per annum payable to the lenders under the Term Loan Facility beginning on January 3, 2023 (the "Closing Date") in respect of the unutilized commitments thereunder. As a result of the incurrence of the Term Loans on the Closing Date such ticking fees were not (and shall not be) payable to the Lenders.

Obligations under the Term Loan Credit Agreement are fully and unconditionally guaranteed, jointly and severally, by us and by certain of our directly or indirectly wholly-owned subsidiaries organized in the United States and are secured by the equity in, and substantially all the assets of, such subsidiaries. The Term Loans were funded in an amount of $250.0 million and applied to finance a portion of the consideration payable in connection with the consummation of the Endura acquisition on January 3, 2023.

The Term Loan Credit Agreement contains restrictive covenants that, among other things, limit our ability and the ability of our subsidiaries to: (i) pay dividends on our common shares and make other restricted payments, (ii) make investments and acquisitions, (iii) engage in transactions with our affiliates, (iv) sell assets, (v) merge, (vi) incur additional debt and (vii) create liens. The Term Loan Credit Agreement includes certain exceptions and exemptions under the restricted payment, investment, dispositions, liens and indebtedness covenants.

The Term Loan Credit Agreement requires us to maintain at all times a total leverage ratio of no more than 4.50:1.00. The Term Loan Credit Agreement contains change of control provisions and certain customary affirmative covenants and events of default. As of December 31, 2023, we were in compliance with all covenants under the credit agreement governing the Term Loan Facility and there were no amounts outstanding.

ABL Facility

On January 31, 2019, we and certain of our subsidiaries entered into a $250.0 million asset-based revolving credit facility (the "ABL Facility") maturing on January 31, 2024, which replaced the previous facility. On October 28, 2022, we and certain of our subsidiaries entered into an amendment which, among other things, (i) increased the revolving credit commitments available thereunder by $100.0 million to an aggregate amount of $350.0 million and (ii) replaced the LIBOR-based interest rate applicable to borrowings thereunder in U.S. dollars with an interest rate based on the sum of (x) a "Term SOFR" rate published by the CME Group Benchmark Administration Limited (CBA) plus (y) 10 basis points ("Adjusted Term SOFR"). Additionally, on December 12, 2022, we entered into an amendment to the ABL Facility, which, among other things, extended the maturity of the ABL Facility from January 31, 2024 to December 12, 2027. The terms of the ABL Facility remained otherwise substantially unchanged. Obligations under the ABL Facility are secured by a first priority security interest in such accounts receivable, inventory and other related assets of Masonite and our subsidiaries. In addition, obligations under the ABL Facility are fully and unconditionally guaranteed, jointly and severally, on a senior secured basis, by certain of our directly or indirectly wholly-owned subsidiaries. 

Borrowings under the ABL Facility bear interest at a rate equal to, at our option, (i) the United States, Canadian or United Kingdom Base Rate (each as defined in the credit agreement relating to the ABL Facility, the "Amended and Restated Credit Agreement") plus a margin ranging from 0.25% to 0.50% per annum, or (ii) the Adjusted Term SOFR or BA Rate (each as defined in the Amended and Restated Credit Agreement), plus a margin ranging from 1.25% to 1.50% per annum. In addition to paying interest on any outstanding principal under the ABL Facility, a commitment fee is payable on the undrawn portion of the ABL Facility in an amount equal to 0.25% per annum of the average daily balance of unused commitments during each calendar quarter.

The ABL Facility contains various customary representations, warranties and covenants by us that, among other things, and subject to certain exceptions, restrict Masonite's ability and the ability of our subsidiaries to: (i) pay dividends on our common shares and make other restricted payments, (ii) make investments and acquisitions, (iii) engage in transactions with our affiliates, (iv) sell assets, (v) merge and (vi) create liens. The ABL Facility, among other things, (i) permits us to incur unlimited unsecured debt as long as such debt does not contain covenants or default provisions that are more restrictive than those contained in the ABL Facility, (ii) permits us to incur debt as long as the pro forma

75

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS (continued)

secured leverage ratio is less than 4.5 to 1.0, and (iii) adds certain additional exceptions and exemptions under the restricted payment, investment and indebtedness covenants (including increasing the amount of certain debt permitted to be incurred under an existing exception). As of December 31, 2023, we were in compliance with all covenants under the credit agreement governing the ABL Facility. We had availability of $273.6 million under our ABL Facility and there were no amounts outstanding as of December 31, 2023.

10. Commitments and Contingencies

We may become involved from time-to-time in litigation and regulatory compliance matters incidental to our business, including employment and wage and hour claims, antitrust, tax, product liability, environmental, health and safety, commercial disputes, intellectual property, contracts and other matters arising out of the normal conduct of our business. Since litigation is inherently unpredictable and unfavorable resolutions can occur, assessing contingencies is highly subjective and requires judgments about future events. We regularly review and accrue for contingencies related to litigation and regulatory compliance matters, if it is probable that a liability has been incurred and the amount of the loss can be reasonably estimated. Based on current information, in the opinion of management, the ultimate resolution of these matters, individually or in the aggregate, will not have a material adverse effect on our financial condition, results of operations or cash flows.

Antitrust Class Action Proceedings - Canada

On May 19, 2020, an intended class proceeding was commenced in the Province of Québec, Canada naming as defendants Masonite Corporation, Corporation Internationale Masonite, JELD-WEN, Inc., JELD-WEN Holding, Inc. and JELD-WEN of Canada, Ltd. The plaintiff alleges that the Masonite and JELD-WEN defendants engaged in anticompetitive conduct, including price-fixing involving interior molded doors. The intended class proceeding seeks damages, punitive damages, and other relief. On December 22, 2020, the parties filed a motion with the court seeking to stay the proceeding.

On October 2, 2020, an intended class proceeding was commenced in the Federal Court of Canada naming as defendants Masonite International Corporation, Masonite Corporation, JELD-WEN, Inc., JELD-WEN Holding, Inc. and JELD-WEN of Canada, Ltd. The plaintiff alleges that the Masonite and JELD-WEN defendants engaged in anticompetitive conduct, including price-fixing involving interior molded doors. The intended class proceeding seeks damages, punitive damages, and other relief. The plaintiff served its certification record on March 31, 2021.

On November 3, 2023, the Company entered into a preliminary settlement agreement with the plaintiff class that would result in the resolution of all the plaintiffs’ underlying claims and lawsuits in exchange for a payment by the Company of approximately $0.9 million. As a result, for the year ended December 31, 2023, we paid approximately $0.9 million and recorded a charge in selling, general and administrative expense in the condensed consolidated

76

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS (continued)

statement of income and comprehensive income in connection with this matter. The preliminary settlement agreement is subject to court approval. A settlement approval hearing date has not yet been set.

11. Revenues

We derive our revenues primarily from the manufacture and delivery of doors and door components as performance obligations that arise from our contracts with customers are satisfied. Materially all of our revenues are generated from contracts with customers and the nature, timing and any uncertainty in the recognition of revenues are not affected by the type of good, customer or geographical region to which the performance obligation relates. Our contracts with our customers are generally in the form of purchase orders and the performance obligation arises upon receipt of the purchase order and agreement upon the transaction price. The performance obligations are satisfied at a point in time when control of the promised goods is transferred to the customer and payment terms vary from customer to customer. Payment terms are short-term, are customary for our industry and in some cases, early payment incentives are offered.

The transaction price recognized as revenue and accounts receivable is determined based upon a number of estimates, including:

•Incentive-based volume rebates, which are based on individual rebate agreements with our customers, as well as historical and expected performance of each individual customer,

•Estimated sales returns, which are based on historical returns as a percentage of revenues, and

•Adjustments for early payment discounts offered by us.

Contract assets are represented by our trade accounts receivable balances on the consolidated balance sheets, and are described in Note 3. Accounts Receivable. There were no other material contract assets or liabilities as of December 31, 2023, or January 1, 2023. Our warranties are assurance-type warranties and do not represent separate performance obligations to our customers. There were no material impairment losses related to contract assets during the years ended December 31, 2023, January 1, 2023, or January 2, 2022.

12. Share Based Compensation Plans

Share based compensation expense was $23.6 million, $21.8 million and $16.0 million for the years ended December 31, 2023, January 1, 2023, and January 2, 2022, respectively. As of December 31, 2023, the total remaining unrecognized compensation expense related to share based compensation amounted to $24.8 million, which will be amortized over the weighted average remaining requisite service period of 1.5 years. Share based compensation expense is recognized using a graded-method approach, or to a lesser extent a straight-line approach, depending on the terms of the individual award, and is classified within selling, general and administration expenses in the consolidated statements of income and comprehensive income. All forfeitures are accounted for as they occur. All share based awards are settled through issuance of new shares of our common stock. The share based award agreements contain restrictions on sale or transfer other than in limited circumstances. All other transfers would cause the share based awards to become null and void.

Equity Incentive Plan

On March 10, 2021, the Board of Directors adopted the Masonite International Corporation 2021 Omnibus Incentive Equity Plan (the "2021 Equity Plan"), which was approved by our shareholders at the Annual General Meeting of Shareholders on May 13, 2021. The 2021 Equity Plan is effective for ten years from the date of approval. The aggregate number of common shares that can be issued with respect to equity awards under the 2021 Equity Plan cannot exceed 880,000 shares; plus the number of shares reserved for the 2012 Plan that is in excess of the number of shares related to outstanding grants; plus the number of shares subject to existing grants under the 2012 Plan that may expire or be forfeited or cancelled.

On July 12, 2012, the Board of Directors adopted the Masonite International Corporation 2012 Equity Incentive Plan, which was amended on June 21, 2013, by our Board of Directors, further amended and restated by our Board of

77

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS (continued)

Directors on February 23, 2015, and approved by our shareholders on May 12, 2015 (as amended and restated, the "2012 Plan").

The 2021 Equity Plan and the 2012 Plan ("the Plans") were adopted because the Board of Directors believes that long-term incentive awards granted under the Plans will help to attract, motivate and retain employees and non-employee directors, align employee and stockholder interests and encourage a performance-based culture built on employee stock ownership. The Plans permit us to offer eligible directors, employees and consultants cash and share-based incentives, including stock options, stock appreciation rights, restricted stock, other share-based awards (including restricted stock units) and cash-based awards. The Plans are effective for ten years from the date of its adoption. Awards granted under the Plans are at the discretion of the Human Resources and Compensation Committee of the Board of Directors. The Human Resources and Compensation Committee may grant any award under the Plans in the form of a performance award. The Plans may be amended, suspended or terminated by the Board at any time; provided, that any amendment, suspension or termination which impairs the rights of a participant is subject to such participant's consent and; provided further, that certain material amendments are subject to shareholder approval. As of December 31, 2023, there were 773,165 shares of common stock available for future issuance under the 2021 Equity Plan.

Deferred Compensation Plan

We offer to certain of our employees and directors a Deferred Compensation Plan ("DCP"). The DCP is an unfunded non-qualified deferred compensation plan that permits those certain employees and directors to defer a portion of their compensation to a future time. Eligible employees may elect to defer a portion of their base salary, bonus and/or restricted stock units and eligible directors may defer a portion of their director fees or restricted stock units. All contributions to the DCP on behalf of the participant are fully vested (other than restricted stock unit deferrals which remain subject to the vesting terms of the applicable equity incentive plan) and placed into a grantor trust, commonly referred to as a "rabbi trust." Although we are permitted to make matching contributions under the terms of the DCP, we have not elected to do so. The DCP invests the contributions in diversified securities from a selection of investments and the participants choose their investments and may periodically reallocate the assets in their respective accounts. Participants are entitled to receive the benefits in their accounts upon separation of service or upon a specified date, with benefits payable as a single lump sum or in annual installments. All plan investments are categorized as having Level 1 valuation inputs as established by the FASB’s Fair Value Framework.

Assets of the rabbi trust, other than Company stock, are recorded at fair value and included in other assets in the consolidated balance sheets. These assets in the rabbi trust are classified as trading securities and changes in their fair values are recorded in other (income) expense, net in the consolidated statements of income and comprehensive income. The liability relating to deferred compensation represents our obligation to distribute funds to the participants in the future and is included in other liabilities in the consolidated balance sheets. As of December 31, 2023, the liability and asset relating to deferred compensation had a fair value of $8.4 million and $7.5 million, respectively. As of January 1, 2023, the liability and asset relating to deferred compensation had a fair value of $7.2 million and $7.0 million, respectively. Any gain or loss relating to changes in the fair value of the deferred compensation liability is recognized in selling, general and administration expense in the consolidated statements of income and comprehensive income.

As of December 31, 2023, participation in the DCP is limited and no restricted stock awards have been deferred into the DCP.

Stock Appreciation Rights

We have granted Stock Appreciation Rights ("SARs") to certain employees, which entitle the recipient to the appreciation in value of a number of common shares over the exercise price over a period of time, each as specified in the applicable award agreement. The exercise price of any SAR granted may not be less than the fair market value of our common shares on the date of grant. The compensation expense for the SARs is measured based on the fair value of the SARs at the date of grant and is recognized over the requisite service period. The SARs vest over a maximum of three years, have a life of ten years and settle in common shares. It is assumed that all time-based SARs will vest.

The total fair value of SARs vested was $0.7 million, $0.8 million and $0.8 million, in the years ended December 31, 2023, January 1, 2023, and January 2, 2022, respectively.

The value of SARs granted in the year ended December 31, 2023, as determined using the Black-Scholes-Merton valuation model, was $1.0 million and is expected to be recognized over the average requisite service period of 2.0 years. Expected volatility is based upon the historical volatility of our common shares amongst other considerations. The expected term is calculated based on historical employee behavior and the contractual term of the options amongst other considerations. The weighted average grant date assumptions used for the SARs granted were as follows for the periods indicated:

Restricted Stock Units

We have granted Restricted Stock Units ("RSUs") to directors and certain employees under the 2021 Equity Plan and the 2012 Plan. The RSUs confer the right to receive shares of our common stock at a specified future date or when certain conditions are met. The compensation expense for the RSUs awarded is based on the fair value of the RSUs at the date of grant, which is equal to the stock price on the date of grant, and is recognized over the requisite service period. The RSUs vest over a maximum of three years and call for the underlying shares to be delivered no later than 30 days following the vesting date unless the participant is subject to a blackout period. In such case, the shares are to be delivered once the blackout restriction has been lifted. It is assumed that all time-based RSUs will vest.

(1) A portion of the vested RSUs delivered were net share settled to cover statutory requirements for income and other employment taxes. We remit the equivalent cash to the appropriate taxing authorities. These net share settlements had the effect of share repurchases by us as we reduced and retired the number of shares that would have otherwise been issued as a result of the vesting.

RSUs granted during the year ended December 31, 2023, vest at specified future dates with only service requirements. The value of RSUs granted in the year ended December 31, 2023, was $19.2 million and is being recognized over the weighted average requisite service period of 2.0 years. During the year ended December 31, 2023, 139,336 RSUs vested at a fair value of $13.0 million.

Performance-based Restricted Stock Units

We have granted certain Performance-based Restricted Stock Units ("PRSUs") under the 2021 Equity Plan and the 2012 Plan. These PRSUs are settled with payouts ranging from zero to 200% of the target award value depending on performance goal achievement. The compensation expense for the PRSUs awarded is based on the fair value of the PRSUs at the date of grant, which is equal to the stock price on the date of grant, and is recognized over the requisite service period. In 2023, we granted certain PRSUs with an additional condition measured by Relative Total Shareholder Return ("TSR"). The compensation expense for these PRSUs is determined using the Monte Carlo simulation method. The PRSUs vest over a maximum of three years and call for the underlying shares to be delivered no later than 30 days following the vesting date unless the participant is subject to a blackout period. In such case, the shares are to be delivered once the blackout restriction has been lifted.

(1) PRSUs are presented as outstanding, granted and forfeited in the table above assuming targets are met and the awards pay out at 100%. Certain awards are settled with payouts ranging from zero to 200% of the target award value depending on achievement. The performance adjustment represents the difference in shares ultimately awarded due to performance attainment above or below target.

(2) A portion of the vested PRSUs delivered were net shares settled to cover statutory requirements for income and other employment taxes. We remit the equivalent cash to the appropriate taxing authorities. These net share settlements had the effect of share repurchases by us as we reduced and retired the number of shares that would have otherwise been issued as a result of the vesting.

PRSUs granted during the year ended December 31, 2023, vest at specified future dates based on both performance and service requirements, while certain PRSUs also vest based on TSR. The value of PRSUs granted in the year ended December 31, 2023, was $9.7 million and is being recognized over the weighted average requisite service period of 3.0 years. During the year ended December 31, 2023, 68,656 PRSUs vested at a fair value of $5.4 million.

13. Restructuring Costs

Over the past several years, we have engaged in a series of restructuring programs related to exiting certain geographies and non-core businesses, consolidating certain internal support functions and engaging in other actions designed to reduce our cost structure and improve productivity. These initiatives primarily consist of severance actions and plant closure costs. Management continues to evaluate our business; therefore, in future years, there may be additional provisions for new plan initiatives, as well as changes in previously recorded estimates, as payments are made or actions are completed. Asset impairment charges were also incurred in connection with these restructuring actions for certain assets sold, abandoned or made obsolete as a result of these programs.

In December 2023, we began implementing a plan to improve overall business performance that includes the optimization of our manufacturing capacity and reduction of our overhead and selling, general and administration workforce primarily in our Europe reportable segment (collectively, the "2024 Plan"). The optimization of our manufacturing capacity involves specific plants in the Europe segment and costs associated with the closure of these plants and related headcount reductions. Costs associated with the 2024 Plan include severance and closure charges and will continue throughout 2024. As of December 31, 2023, we expect to incur approximately $6 million to $9 million of additional charges related to the 2024 Plan.

In December 2022, we began implementing a plan to improve overall business performance that includes the optimization of our manufacturing capacity and reduction of our overhead and selling, general and administration workforce primarily in our North American Residential reportable segment as well as actions in the Architectural reportable segment and in our head offices (collectively, the "2022 Plan"). The optimization of our manufacturing capacity involves specific plants in the North American Residential segment and costs associated with the closure of these plants and related headcount reductions. Costs associated with the 2022 Plan include severance and closure charges

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS (continued)

and will continue throughout 2024. As of December 31, 2023, we expect to incur approximately $3 million to $8 million of additional charges related to the 2022 Plan.     

As previously stated, we have engaged in restructuring programs over the past several years. The 2019, 2020, and 2021 restructuring programs have been aggregated as "Other Plans" for this note. As of December 31, 2023, we do not expect to incur any material future charges related to the Other Plans.

14. Asset Impairment

During the year ended December 31, 2023, we recognized asset impairment charges of $33.1 million, net of foreign currency translation, related to a goodwill impairment charge in the Europe reporting unit due to weakening consumer confidence in the United Kingdom that continues to affect demand in the repair and remodel market, negative impacts from rising energy and fuel costs, partly attributable to geopolitical conflicts, as well as rising costs for raw materials and material supply constraints. The quantitative impairment test was conducted using multiple valuation techniques, including a discounted cash flow analysis and market approach, which utilizes Level 3 fair value inputs, and resulted in a goodwill impairment charge. The charge represents the amount by which the carrying value of the Europe reporting unit exceeded its fair value, and was recorded in the consolidated statements of income and comprehensive income and reduced the goodwill balance in the Europe reporting unit from $60.0 million to $26.8 million, excluding foreign exchange fluctuations. See Note 7 for further information.

During the year ended January 2, 2022, we recognized asset impairment charges of $69.9 million, of which $59.5 million related to a goodwill impairment charge in the Architectural reporting unit as a result of manufacturing constraints due to COVID-19 related absenteeism, material availability and production challenges and $10.4 million related to assets in the Architectural segment and an asset in the Corporate & Other category as a result of announced plant closures under the 2021 and 2020 Plans. The quantitative impairment test in the Architectural reporting unit was conducted using multiple valuation techniques, including a discounted cash flow analysis and market approach, which utilizes Level 3 fair value inputs, and resulted in the goodwill impairment charge. The $10.4 million charge represents the amount by which the carrying value of the Architectural reporting unit exceeded its fair value and reduced the goodwill balance from $59.5 million to zero. The asset impairment charge was determined based upon the excess of the carrying values of property, plant and equipment over the respective fair values of such assets, determined using a discounted cash flows approach for each asset group. The fair value of the assets was determined to be $6.3 million, compared to a book value of $16.7 million, with the difference representing the asset impairment charges recorded in the consolidated statements of income and comprehensive income.

Each of these valuations was performed on a non-recurring basis and is categorized as having Level 3 valuation inputs as established by the FASB's Fair Value Framework. The Level 3 unobservable inputs include an estimate of future cash flows and the salvage value for each of the assets.

Management assesses the available positive and negative evidence to estimate if sufficient future taxable income will be generated to use the existing deferred tax assets.

As of December 31, 2023, and January 1, 2023, a valuation allowance of $12.1 million and $14.1 million, respectively, has been established to reduce the deferred tax assets to an amount that is more likely than not to be realized. We have established valuation allowances on certain deferred tax assets resulting from loss carryforwards and other assets in Canada, Costa Rica and the United Kingdom.

The following is a rollforward of the valuation allowance for deferred tax assets:

The losses carried forward for tax purposes are available to reduce future taxable income by $108.2 million. We can apply these losses against future taxable income based on the period of expiration as follows:

Indefinitely	—		30,598		30,598
Total tax losses carried forward	$	74,186	$	33,974	$	108,160

We have outside basis differences, including undistributed earnings in our foreign subsidiaries. For those subsidiaries in which we are considered to be indefinitely reinvested, no provision for Canadian income or local country withholding taxes has been recorded. Upon reversal of the outside basis difference and/or repatriation of those earnings, in the form of dividends or otherwise, we may be subject to both Canadian income taxes and withholding taxes payable to the various foreign countries. For those subsidiaries where the earnings are not considered indefinitely reinvested, taxes have been accrued. The determination of the unrecorded deferred tax liability for temporary differences related to investments in foreign subsidiaries that are considered to be indefinitely reinvested is not considered practicable.

As of December 31, 2023, and January 1, 2023, our unrecognized tax benefits were $6.8 million and $7.7 million, respectively, excluding interest and penalties. The unrecognized tax benefits would favorably impact the effective tax rate if the tax benefits were recognized. The unrecognized tax benefits are recorded in other long-term liabilities and as a reduction to related long-term deferred income taxes in the consolidated balance sheets. The changes to our unrecognized tax benefits were as follows:

	Year Ended
(In thousands)	December 31, 2023		January 1, 2023		January 2, 2022
Unrecognized tax benefit at beginning of period	$	7,680	$	7,592	$	8,108

Lapse of statute of limitations	(523)		—		(511)
Unrecognized tax benefit at end of period	$	6,831	$	7,680	$	7,592

We recognize interest and penalties accrued related to unrecognized tax benefits as income tax expense. During the years ended December 31, 2023, January 1, 2023, and January 2, 2022, we recorded accrued interest of $0.7 million, $0.6 million and $0.4 million, respectively. Additionally, we have recognized a liability for accumulated penalties of $0.2 million, $0.3 million and $0.3 million, and accumulated interest of $3.2 million, $3.1 million and $2.8 million, respectively. The interest and penalties accrued related to unrecognized tax benefits would also favorably impact the effective tax rate if those benefits were recognized.

We estimate that the amount of unrecognized tax benefits will decrease within the 12 months following the reporting date by approximately $4.5 million due to lapse of statute of limitations.

We are subject to taxation in Canada, the United States and other foreign jurisdictions. As of December 31, 2023, we are no longer subject to Canadian income tax examination for years prior to 2019. Additionally, we are no longer subject to U.S. federal tax examinations for years prior to 2020. To the extent that income tax attributes such as net operating losses and tax credits have been carried forward from years prior to 2020, those attributes can still be audited when utilized on returns subject to audit. In state and local jurisdictions, we are no longer subject to income tax examination for years prior to 2017.

On August 16, 2022, President Biden signed the Inflation Reduction Act of 2022 ("IRA") into law. The IRA includes several changes to existing tax law, including a minimum tax on adjusted financial statement income of applicable corporations and an excise tax on certain corporate stock buybacks. The tax provisions included in the IRA

are generally effective beginning January 1, 2023, and there was no significant impact to the consolidated financial statements as of December 31, 2023.

16. Earnings Per Share

Basic earnings per share ("EPS") is calculated by dividing earnings attributable to Masonite by the weighted average number of our common shares outstanding during the period. Diluted EPS is calculated by dividing earnings attributable to Masonite by the weighted average number of common shares plus the incremental number of shares issuable from non-vested and vested RSUs and SARs outstanding during the period.

	Year Ended
(In thousands, except share and per share information)	December 31, 2023		January 1, 2023		January 2, 2022
Net income attributable to Masonite	$	118,227	$	214,233	$	94,501
Shares used in computing basic earnings per share	22,031,168		22,532,722		24,176,846
Effect of dilutive securities:
Incremental shares issuable under share compensation plans	314,312		239,743		385,687
Shares used in computing diluted earnings per share	22,345,480		22,772,465		24,562,533
Basic earnings per common share attributable to Masonite	$	5.37	$	9.51	$	3.91
Diluted earnings per common share attributable to Masonite	$	5.29	$	9.41	$	3.85
Anti-dilutive instruments excluded from diluted earnings per common share	97,805		223,968		28,707

The weighted average number of shares outstanding utilized for the diluted EPS calculation contemplates the exercise of all currently outstanding SARs and the conversion of all RSUs. The dilutive effect of such equity awards is calculated based on the weighted average share price for each fiscal period using the treasury stock method.

The Company's Board of Directors approved five share repurchase authorizations, the most recent being an incremental $200.0 million share repurchase program approved on February 21, 2022. In addition, the Company announced that its Board of Directors authorized it to enter into an accelerated share repurchase ("ASR") transaction as part of the new share repurchase program. The Company entered into an ASR transaction during the first quarter of 2022 with a third-party financial institution for the repurchase of $100.0 million of its outstanding common shares. At inception, pursuant to the agreement, the Company paid $100.0 million to the financial institution using cash on hand and received an initial delivery of 848,087 common shares on the same day. The final delivery of 319,678 common shares occurred in the second quarter. The $100.0 million ASR transaction was therefore completed in the second quarter with a total delivery of 1,167,765 common shares at a volume-weighted average price ("VWAP") per share minus an agreed upon discount totaling 85.63 per share. The cash paid was reflected as a reduction of equity at the initial delivery of shares and the number of shares outstanding were reduced at the dates of physical delivery.

The Arrangement Agreement (as defined herein) with Owens Corning restricts our ability to repurchase our shares and therefore our share repurchase program is currently suspended through February 8, 2025, other than for the repurchase of shares associated with tax withholding requirements for share-based compensation.

17. Segment Information

    Our management reviews net sales and Adjusted EBITDA (as defined below) to evaluate segment performance and allocate resources. Net assets are not allocated to the reportable segments. Adjusted EBITDA is a non-GAAP financial measure which does not have a standardized meaning under GAAP and is unlikely to be comparable to similar measures used by other companies. Adjusted EBITDA should not be considered as an alternative to either net income or

88

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS (continued)

operating cash flows determined in accordance with GAAP. Adjusted EBITDA is defined as net income (loss) attributable to Masonite adjusted to exclude the following items:

•    depreciation;

•    amortization;

•    share based compensation expense;

•    loss (gain) on disposal of property, plant and equipment;

•    registration and listing fees;

•    restructuring costs (benefit);

•    asset impairment;

•    loss (gain) on disposal of subsidiaries;

•    interest expense (income), net;

•    loss on extinguishment of debt;

•    other expense (income), net;

•    income tax expense (benefit);

•    other items;

•    loss (income) from discontinued operations, net of tax; and

•    net income (loss) attributable to non-controlling interest.

The definition of Adjusted EBITDA differs from the definitions of EBITDA contained in the indenture governing the 2030 Notes and the 2028 Notes and the credit agreements governing the Term Loan Facility and the ABL Facility. Although Adjusted EBITDA is not a measure of financial condition or performance determined in accordance with GAAP, it is used to evaluate and compare the operating performance of the segments and it is one of the primary measures used to determine employee incentive compensation.

Certain information with respect to reportable segments is as follows for the periods indicated:

18. Employee Future Benefits

United States Defined Benefit Pension Plan

We had a defined benefit pension plan covering certain active and former employees in the United States ("U.S. Pension Plan"). Benefits under the plan were frozen at various times in the past. On December 9, 2020, the Board of Directors approved a resolution to terminate the U.S. Pension Plan and we initiated the process to terminate and annuitize the plan, which continued into 2021. During the fourth quarter of 2021, we completed balance sheet risk mitigation actions related to the U.S. Pension Plan and terminated the plan. In connection with the plan termination, we settled all future obligations under the U.S. Pension Plan through a combination of lump-sum payments to eligible participants who elected to receive them, and the transfer of any remaining benefit obligations to a third-party insurance company under a group annuity contract, which resulted in the settlement of liabilities to affected participants. As a result of these actions, we recognized a pre-tax pension settlement charge of $23.3 million in the fourth quarter of 2021, primarily comprised of the recognition of past actuarial losses. This charge is recorded within other (income) expense, net in the consolidated statements of income and comprehensive income. Information about the U.S. Pension Plan is as follows for the periods indicated:

The rate of compensation increase for the accrued benefit obligation and net periodic pension costs for the U.S. Pension Plan is not applicable, as benefits under the plan are not affected by compensation increases.

The expected long-term rate of return on plan assets assumption was derived by taking into consideration the target plan asset allocation, historical rates of return on those assets, projected future asset class returns and net outperformance of the market by active investment managers. An asset return model was used to develop an expected range of returns on the plan investments over a 30-year period, with the expected rate of return selected from a best estimate range within the total range of projected results.

United Kingdom Defined Benefit Pension Plan

We have a defined benefit pension plan in the United Kingdom ("U.K. Pension Plan"), which has been curtailed in prior years. The measurement date used for the accounting valuation of the U.K. Pension Plan was December 31, 2023. Information about the U.K. Pension Plan is as follows for the periods indicated:

There were $0.4 million of actuarial gains during fiscal year 2023 primarily as a result of asset returns exceeding expectations over the year and future inflation being lower than previously anticipated. In addition, demographic assumptions were updated to imply lower life expectancy and lead to lower liabilities. This change was partially offset by the discount rate decreasing from 4.81% to 4.48%. There were $9.2 million of actuarial gains during fiscal year 2022 primarily as a result of a change in the discount rate from 1.83% to 4.81%. There were no material changes to any other key assumptions nor was there a significant demographic gain or loss.

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS (continued)

The net plan assets are recorded within other assets in the consolidated balance sheets. Pension fund assets are invested primarily in equity and debt securities. Asset allocation between equity and debt securities and cash is adjusted based on the expected life of the plan and the expected retirement age of the plan participants. Information with respect to the amounts and types of securities that are held in the U.K. Pension Plan is set forth as follows for the periods indicated:

	Year Ended
	December 31, 2023				January 1, 2023

Equity securities	$	4,511	21.3	%	$	3,740	20.7	%

	$	21,199	100.0	%	$	18,082	100.0	%

Under the plan's investment policy and strategy, plan assets are invested to achieve a fully funded status based on actuarial calculations, maintain a level of liquidity that is sufficient to pay benefit and expense obligations when due, maintain flexibility in determining the future level of contributions and maximize returns within the limits of risk. The target asset allocation for plan assets in the U.K. Pension Plan for 2023 is 80% other securities and 20% equity securities. Other securities represent investments that are primarily invested in a mixture of debt and equity securities.

The weighted average actuarial assumptions adopted in measuring our U.K. accrued benefit obligations and costs were as follows for the periods indicated:

	Year Ended
	December 31, 2023		January 1, 2023		January 2, 2022
Discount rate applied for:
Accrued benefit obligation	4.5	%	4.8	%	1.8	%
Net periodic pension cost	4.8	%	1.7	%	1.0	%
Expected long-term rate of return on plan assets	4.3	%	3.0	%	4.1	%

The rate of compensation increase for the accrued benefit obligation and net pension cost for the U.K. Pension Plan is not applicable, as the plan was curtailed in prior years and benefits under the plan are not affected by compensation increases.

The expected long-term rate of return on plan assets assumption is derived by taking into consideration the target plan asset allocation, historical rates of return on those assets, projected future asset class returns and net outperformance of the market by active investment managers. An asset return model is used to develop an expected range of returns on the plan investments over a 10-year period, with the expected rate of return selected from a best estimate range within the total range of projected results.

Overall Pension Obligation

For all periods presented, the U.S. and U.K. Pension Plans were invested in equity securities, equity funds, bonds, bond funds and cash and cash equivalents. All investments are publicly traded and possess a high level of marketability or liquidity. All plan investments are categorized as having Level 1 valuation inputs as established by the FASB’s Fair Value Framework.

The change in the net difference between the pension plan assets and projected benefit obligation that is not attributed to our recognition of pension expense or funding of the plan is recognized in other comprehensive (loss) income within the consolidated statements of income and comprehensive income and the balance of such changes is included in AOCL in the consolidated balance sheets.

Defined Contribution Benefit Plans

We have defined contribution benefit plans covering certain U.S. and foreign subsidiary employees subject to eligibility requirements set up in accordance with local statutory requirements. Contributions made to these plans were $16.5 million, $16.1 million and $15.6 million for the years ended December 31, 2023, January 1, 2023, and January 2, 2022, respectively.

Cumulative translation adjustments are reclassified out of accumulated other comprehensive loss into loss on disposal of subsidiaries in the year ended January 1, 2023, in the consolidated statements of income and comprehensive income. Actuarial net losses are reclassified out of accumulated other comprehensive loss into cost of goods sold in the consolidated statements of income and comprehensive income. Pension settlement charges are reclassified out of accumulated other comprehensive loss into other (income) expense, net, in the consolidated statements of income and comprehensive income.

Foreign currency translation gains as a result of translating our foreign assets and liabilities into U.S. dollars during the year ended December 31, 2023, were $19.1 million, primarily driven by strengthening of the Pound Sterling, the Canadian Dollar, the Mexican Peso, and the Euro in comparison to the U.S. dollar during the period.

During the fourth quarter of 2018, we provided debt financing to a distribution company via an interest-bearing note that was scheduled to mature in 2028. The interest-bearing note receivable was carried at amortized cost, with the interest payable in kind at the election of the borrower. The note receivable balance was $12.6 million as of January 1, 2023. The note receivable was recorded in the consolidated balance sheets as a component of prepaid expenses and other assets as of January 1, 2023. On January 26, 2023, the note receivable was redeemed and fully repaid.

21. Variable Interest Entity

As of December 31, 2023, and January 1, 2023, we held an interest in one variable interest entity ("VIE"), Magna Foremost Sdn Bhd, which is located in Bintulu, Malaysia. The VIE is integrated into our supply chain and manufactures door facings. We are the primary beneficiary of the VIE based on the terms of the existing supply agreement with the VIE. As primary beneficiary via the supply agreement, we receive a disproportionate amount of earnings on sales to third parties in relation to our voting interest, and as a result, receive a majority of the VIE’s residual returns. Sales to third parties did not have a material impact on our consolidated financial statements. We also have the power to direct activities of the VIE that most significantly impact the entity’s economic performance. As its primary beneficiary, we have consolidated the results of the VIE. Our net cumulative investment in the VIE was comprised of the following as of the dates indicated:

Current assets include $3.0 million and $1.0 million of cash and cash equivalents as of December 31, 2023, and January 1, 2023, respectively. Assets recognized as a result of consolidating this VIE do not represent additional assets that could be used to satisfy claims against our general assets. Furthermore, liabilities recognized as a result of consolidating these entities do not represent additional claims on our general assets; rather, they represent claims against the specific assets of the consolidated VIE.

22. Fair Value of Financial Instruments

The carrying amounts of our cash and cash equivalents, restricted cash, accounts receivable, income taxes receivable, accounts payable, accrued expenses and income taxes payable approximate fair value because of the short-term maturity of those instruments. The carrying amount of our Term Loan Facility approximates fair value as the interest rates are variable and reflective of market rates. The estimated fair values and carrying values of our long-term debt instruments were as follows for the periods indicated:

	December 31, 2023				January 1, 2023
(In thousands)	Fair Value		Carrying Value		Fair Value		Carrying Value
3.50% senior unsecured notes due 2030	$	324,956	$	371,679	$	303,870	$	371,136
5.375% senior unsecured notes due 2028	$	482,285	$	496,609	$	462,495	$	495,868

These estimates are based on market quotes and calculations based on current market rates available to us and are categorized as having Level 2 valuation inputs as established by the FASB’s Fair Value Framework. Market quotes used in these calculations are based on bid prices for our debt instruments and are obtained from and corroborated with multiple independent sources. The market quotes obtained from independent sources are within the range of management’s expectations.

23. Subsequent Events

Arrangement Agreement with Owens Corning

On February 8, 2024, we entered into an Arrangement Agreement (the “Arrangement Agreement”) with Owens Corning (“Owens Corning”), a Delaware corporation, and MT Acquisition Co LLC (“Purchaser”), a British Columbia unlimited liability company and a wholly owned subsidiary of Owens Corning. Subject to the terms and conditions of the Arrangement Agreement, Owens Corning, through Purchaser, agreed to acquire the Company for $133.00 per issued and outstanding share of our common stock, no par value (the “Shares”), in an all-cash transaction. Pursuant to the Arrangement Agreement, following consummation of implementation of a court-approved plan of arrangement under the Business Corporations Act (British Columbia) (the “Acquisition”), the Company will be a wholly owned subsidiary of Owens Corning.

Pursuant to the terms of the Arrangement Agreement, and subject to the terms and conditions set forth therein, at the effective time of the Acquisition (the “Effective Time”), each Share (other than any Share that is held by Owens Corning or any of its subsidiaries or any Share as to which dissent rights have been properly exercised by the holder

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS (continued)

thereof in accordance with British Columbia law) issued and outstanding immediately prior to the Effective Time will be cancelled and automatically converted into the right to receive $133.00 in cash, without interest.

If the Arrangement Agreement is terminated under certain specified circumstances, we or Owens Corning will be required to pay a termination fee. We will be required to pay Owens Corning a termination fee of $75.0 million under specified circumstances, including (a) termination of the Arrangement Agreement in connection with our entry into an agreement with respect to a Superior Proposal (as defined in the Arrangement Agreement) prior to us receiving stockholder approval of the Acquisition, (b) termination by Owens Corning upon an Adverse Recommendation Change (as defined in the Arrangement Agreement), or (c) termination in certain circumstances by either Owens Corning or us upon failure to obtain Masonite Shareholder Approval (as defined in the Arrangement Agreement) or by Owens Corning if we breach our representations, warranties or covenants in a manner that would result in a failure of an applicable closing condition to be satisfied and, if curable, we fail to cure such breach during specific time periods, in each case, if certain other conditions are met. Owens Corning will be required to pay us a reverse termination fee under specified circumstances, including termination of the Arrangement Agreement due to a permanent injunction arising from Competition Laws (as defined in the Arrangement Agreement) when we are not then in material breach of any provision of the Arrangement Agreement and if certain other conditions are met, in an amount equal to $150.0 million.

The consummation of the Acquisition is subject to customary closing conditions, including, among others, (1) the adoption of a resolution approving the Acquisition by at least two-thirds of the votes cast on such resolution by our stockholders entitled to vote thereon and represented in person or by proxy at the applicable special meeting of our stockholders, (2) the issuance of interim and final orders by the Supreme Court of British Columbia approving the Acquisition, (3) the expiration or termination of any applicable waiting period or periods under the Hart-Scott-Rodino Antitrust Improvements Act of 1976 (as amended) and the receipt of certain required regulatory clearances and approvals in other jurisdictions under applicable antitrust and foreign direct investment laws and regulations, including in Canada, Mexico and the United Kingdom, and (4) absence of any law, injunction, order or other judgment prohibiting, rendering illegal or permanently enjoining the consummation of the Acquisition. Each party’s obligation to consummate the Acquisition is also subject to the accuracy of the other party’s representations and warranties contained in the Agreement (subject, with specified exceptions, to materiality or “Material Adverse Effect” standards), the other party’s performance of its covenants and agreements in the Agreement in all material respects, and in the case of Purchaser’s obligation to consummate the Acquisition, the absence of any “Material Adverse Effect” relating to us.

PGTI

On December 17, 2023, the Company entered into an Agreement and Plan of Merger (the “Merger Agreement”) with PGT Innovations, Inc., (“PGTI”) in which Masonite would have acquired PGTI for a combination of cash and Masonite shares with a total transaction value of $3.0 billion. On January 15, 2024, PGTI delivered to Masonite a notice of receipt of a Superior Proposal (as defined in the Merger Agreement) in accordance with Section 6.04(d) of the Merger Agreement. On January 16, 2024, Masonite agreed to waive the four business day match period provided under the Merger Agreement. Accordingly, on January 16, 2024, PGTI terminated the Merger Agreement pursuant to Section 10.01(d)(i) thereunder, and, consistent with the terms of the Merger Agreement, paid to Masonite a termination fee of $84.0 million in cash. The termination fee will be recognized as other income in the consolidated statements of income and comprehensive income in 2024.

Item 9. Changes in and Disagreements with Accountants on Accounting and Financial Disclosure

    None.

Item 9A. Controls and Procedures

Disclosure Controls and Procedures

We maintain disclosure controls and procedures as defined in Rule 13a-15(e) under the Exchange Act that are designed to ensure that information required to be disclosed in our Exchange Act reports is recorded, processed, summarized and reported within the time periods specified in the Securities and Exchange Commission’s rules and forms and that such information is accumulated and communicated to management, including our Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure.

Management, with the participation of our Chief Executive Officer and Chief Financial Officer, has evaluated the effectiveness of our disclosure controls and procedures as of the end of the period covered by this Annual Report. Based on that evaluation, the Chief Executive Officer and the Chief Financial Officer have concluded that, as of the end of the period covered by this Annual Report, our disclosure controls and procedures were not effective because of the material weakness in internal control over financial reporting described below.

Notwithstanding the above, the material weakness did not result in any material misstatements to the consolidated financial statements. Further, management believes and has concluded that the consolidated financial statements included in this report fairly present, in all material respects, the Company's 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.

Management's Annual Report on Internal Control Over Financial Reporting

Management is responsible for establishing and maintaining adequate internal control over financial reporting (as defined in Rule 13a-15(f) under the Exchange Act). Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Projections of any evaluation of effectiveness to future periods are subject to the risk that certain controls may become inadequate because of changes in conditions or that the degree of compliance with the policies or procedures may deteriorate.

Under the supervision and with the participation of management, including our Chief Executive Officer and Chief Financial Officer, we carried out an evaluation of the effectiveness of our internal control over financial reporting as of December 31, 2023, based on the Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission in 2013.

As disclosed in Note 2 to the consolidated financial statements in Item 8 of this Annual Report, we acquired two businesses during the year ended December 31, 2023. In accordance with SEC regulations, management excluded acquisitions completed during 2023 from our assessment of internal control over financial reporting as of December 31, 2023, which Endura and Fleetwood comprised 8% and 1% of our consolidated net sales for the year ended December 31, 2023, respectively, and 28% of our consolidated total assets as of December 31, 2023. Based upon our evaluation, management concluded that our internal control over financial reporting was not effective as of December 31, 2023 due to a material weakness in its controls over business combinations, specific to the sufficiency of evidence supporting management's review activities.

The Company is currently taking actions to remediate this deficiency and believes that the implementation of business combination controls relating to finalizing the preliminary purchase allocations or to new business combinations will substantially remediate the material weakness identified. As we continue to evaluate and take actions to improve our internal control over financial reporting, we may determine to take additional actions to address control deficiencies or determine to modify certain of the remediation measures described above.

The effectiveness of our internal control over financial reporting as of December 31, 2023, has been audited by Ernst & Young, an independent registered public accounting firm, as stated in their report which is included below, and which expresses an adverse opinion on the effectiveness of our internal control over financial reporting as of December 31, 2023. See "Report of Independent Registered Public Accounting Firm" below.

Changes in Internal Control over Financial Reporting

101

Except for the determination by management of the material weakness in internal controls over financial reporting described above, there have been no changes in our internal control over financial reporting during the most recently completed quarter covered by this Annual Report that have materially affected, or that are reasonably likely to materially affect, our internal control over financial reporting.

Report of Independent Registered Public Accounting Firm

To the Shareholders and the Board of Directors of Masonite International Corporation

Opinion on Internal Control Over Financial Reporting

We have audited Masonite International Corporation’s internal control over financial reporting as of December 31, 2023, based on criteria established in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework) (the COSO criteria). In our opinion, because of the effect of the material weakness described below on the achievement of the objectives of the control criteria. Masonite International Corporation (the Company) has not maintained effective internal control over financial reporting as of December 31, 2023, based on the COSO criteria.

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 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 related to the accounting for the Company's business combinations. The material weakness is specific to the sufficiency of evidence supporting Management's review activities.

As indicated in the accompanying Management’s Annual Report on Internal Control Over Financial Reporting, management’s assessment of and conclusion on the effectiveness of internal control over financial reporting did not include the internal controls of EPI Holdings, Inc. (Endura) or Fleetwood Aluminum Products, LLC. (Fleetwood), which are included in the 2023 consolidated financial statements of the Company. For the year ended December 31, 2023, Endura and Fleetwood constituted 8% and 1% of net sales, respectively. As of December 31, 2023, Endura and Fleetwood constituted a combined 28% of total assets. Our audit of internal control over financial reporting of the Company also did not include an evaluation of the internal control over financial reporting of Endura or Fleetwood.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated balance sheets of Masonite International Corporation as of December 31, 2023 and January 1, 2023, the related consolidated statements of income and comprehensive income, changes in equity and cash flows for each of the three years in the period ended December 31, 2023, and the related notes. This material weakness was considered in determining the nature, timing and extent of audit tests applied in our audit of the 2023 consolidated financial statements, and this report does not affect our report dated February 29, 2024, which expressed an unqualified opinion thereon.

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 Annual 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. 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

103

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.

2024 Masonite Incentive Plan (MIP)

Plan Document

Overview

This document sets forth the terms and conditions of the Masonite International Corporation Incentive Plan (the “MIP” or “Plan”) and is intended for internal use only. This Plan supersedes any previous annual incentive or other bonus plans for Participants (as defined below).

The MIP is an annual cash incentive compensation program, providing for payments of awards under the Plan (each, a “MIP Award”) to eligible employees of Masonite International Corporation (“Masonite” or the “Company”) and its subsidiaries and affiliates if certain performance objectives are met. The purpose of the MIP is to reward Participants for the achievement of positive results based on annual financial and operational objectives and individual performance.

The Plan is administered based on the Company’s fiscal year (the “Plan Year”). The Company’s fiscal year is the 52- or 53-week period ending on the Sunday closest to December 31 each year.

Eligibility and Participation

Employees of Masonite or its subsidiaries and affiliates are eligible to participate in the MIP based on their position and scope of responsibilities. The Plan Administrator (as defined below), with input from members of Masonite’s senior management, shall determine which such employees will become participants in the Plan (a “Participant”) for a Plan Year based on their position. The Plan Administrator reserves the right to evaluate positions on an annual basis to determine eligibility to participate in the Plan. Employees who are selected to participate in the Plan for the first time will be notified of their participation.

Impact of Changes in Employment Status

The table below summarizes the impact of employment status changes by a Participant during a Plan Year on MIP Award eligibility and payout for such Plan Year. These provisions may be interpreted by the Plan Administrator in its sole discretion and are subject to compliance with applicable law and such other terms and conditions set forth herein. Note that, for the sake of administrative simplicity and consistency of application, all pro-rating for newly eligible participants and those participants with changes during a Plan Year which impact their final payout for that year will be calculated on a calendar year basis (i.e., January 1 through December 31) with 365 days as the baseline (or 366 for Leap Years).

2

Employment Event Occurring During a Plan Year	Eligibility / Payout
New Hires/Rehires	Eligible to participate in the Plan and will be pro-rated based on their date of hire/rehire through December 31 of the year of hire.
Positions from a Newly Acquired Business	Eligibility to participate in the Plan is determined case-by-case, in the Plan Administrator’s sole discretion.
Transfers, Position Changes and Promotions	Eligibility to participate in the Plan may be pro-rated based on the effective date of the change. Participation will be pro-rated based on the period employed in the applicable position in each business/country during the year of the change.
Demotions	The Plan Administrator may, in its sole discretion, provide for a pro-rated payment of the MIP Award for such Plan Year based on the facts and circumstances of each case for the eligible period prior to the demotion.
LOA/Disability/Workers’ Compensation	Payout of the MIP Award for such Plan Year is pro-rated based on the period during the Plan Year in which the Participant was actively employed.
Termination due to Retirement,1 Disability or Death	The Plan Administrator may, in its sole discretion, provide for a pro-rated payment of the MIP Award for such Plan Year based on the facts and circumstances of each case.
Termination by the Company without Cause (as determined by the Plan Administrator in its sole discretion)	No payout, except to the extent specifically required by applicable law; provided, that the Plan Administrator may, in its sole discretion, provide for a pro-rated payment based on the period employed during such Plan Year based on the facts and circumstances of each case.
Termination by the Company for Cause	No payout.
Termination by Participant for any reason	No payout, except to the extent specifically required by applicable law.

1 “Retirement” means a voluntary termination of employment by a Participant who is age 55 or older with 10 or more years of service with the Company and its subsidiaries and affiliates.

Deferral Opportunities

Notwithstanding any other provision of the Plan to the contrary, if any MIP Award payable under the Plan is subject to a valid deferral election under the terms of another plan or arrangement maintained by the Company (including the Masonite Savings Plan or the Masonite International Corporation Deferred Compensation Plan), the payment of such MIP Award shall be made in accordance with, and subject to, such deferral election.

Target Bonus Percentage

Each Plan Year, the Plan Administrator will establish a target bonus (expressed as a percentage of annual base salary) for each Participant (the “Target Bonus Percentage”) that will apply for purposes of determining the amount of any MIP Award that may become payable under the Plan for such Plan Year.

3

Performance Measures

Each Plan Year, the Human Resources and Compensation Committee of Masonite’s Board of Directors (the “Committee”) will approve the applicable performance measures, including any adjustments thereto, weighting of performance measures, payout parameters and specific targets at threshold, target and maximum levels of performance for each performance measure that will apply to MIP Awards payable under the Plan for such Plan Year. Participants will be advised of the performance measures applicable to their MIP participation for the Plan Year, including their respective Target Bonus Percentage.

For most MIP performance measures, the level of achievement of the applicable performance measures will result in the following payout:

(i)    achievement below the threshold performance level results in no payout,

(ii)    achievement at the threshold level results in a payout at less than 100% of the bonus target,

(iii)    achievement at the target level results in a payout at 100% of the bonus target; and

(iv)    achievement at or above the maximum performance level results in a payout at greater than 100% of the applicable bonus target.

Performance measures may have additional achievement levels between threshold and target and/or target and maximum. The payout percentage for performance between any of threshold, target, or maximum or any additional achievement levels is determined using straight-line interpolation between the two points. Certain performance measures may have threshold and maximum payouts set at different levels. The percentage payout below target for achievement of the threshold performance level and the percentage payout above target for achievement at or above the maximum performance level may vary for each performance measure.

Notwithstanding the foregoing, the Committee shall have discretion each Plan Year to establish a minimum performance measure threshold which must be met for such Plan Year for any MIP Award to become payable under the MIP regardless of the level at which any other performance measures are achieved.

In addition to the performance measures described above, each participant shall receive an Individual Performance Multiplier (IPM) as part of the final calculated bonus each Plan Year, based on their personal performance and contributions during the Plan Year. In particular, the IPM will be based on each participant’s defined Goals and Objectives for the Plan Year, previously agreed upon by each participant and their manager during the Performance Management Goal-Setting process. See below for an explanation of the calculation of the final bonus payouts.

Payout

Following the completion of the Company’s fiscal year, the Plan Administrator will evaluate the applicable performance measures for purposes of determining the amount of any MIP Awards payable under the Plan for the Plan Year. The Plan Administrator will take into account the Company’s audited financial results with respect to any financial or operational performance measures and evaluations and recommendations of appropriate members of management of the Company with respect to individual performance. The actual bonus payout for each

4

Participant is calculated by multiplying (1) the amount of his or her annual base salary payable during the Plan Year (as may be adjusted pursuant to the table under the section entitled “Impact of Changes in Employment Status”), multiplied by (2) his or her Target Bonus Percentage, multiplied by (3) the MIP payout percentage as determined by the Plan Administrator based upon the level of achievement of the applicable performance measures for such Plan Year and modified by a multiplier ranging from 0.75 to 1.25, based on each participant’s performance and contributions during the Plan Year, as assessed by their manager and approved by their Masonite Leadership Team (MLT) leader and the Plan Administrator. Payout levels will be measured and rounded to the nearest one-tenth of one percent (0.1%) for each metric and then summed across all metrics to achieve the final payout.

A Participant must be an Active Employee of the Company on the date MIP Awards are paid out to be eligible to receive a MIP payment, unless otherwise expressly provided in this Plan (see the table under the section entitled “Impact of Changes in Employment Status”) or required by applicable law. For purposes of the Plan, the term “Active Employee” means an employee who is actively employed by the Company or any of its subsidiaries or affiliates, including those employees on approved leaves of absence. Any Participant who is either suspended for disciplinary actions or under a performance improvement plan on the date MIP Awards are paid out may have payment of his or her MIP Award delayed or denied, as determined in the sole discretion of the Plan Administrator or the Senior Vice President of Human Resources (“SVP of HR”).

Form and Timing of Payout

MIP Awards for a Plan Year will be paid to Participants no later than two and one half (2-1/2) months following the end of the Plan Year to which the MIP Award relates, in the form of a single lump-sum cash payment. Payments are subject to all applicable payroll tax withholding and other deductions as required by applicable law. Payment of MIP Awards will be made via regular payroll processing.

Code Section 409A

MIP Awards payable under the Plan are intended to be exempt from the requirements of Code Section 409A and the regulations and other guidance issued thereunder and shall not constitute “deferred compensation” within the meaning of Code Section 409A (absent a valid deferral election under the terms of another plan or arrangement maintained by the Company). The Plan shall be interpreted, construed and administered in accordance with the foregoing intent. The Company shall have no liability as to any Participant or any other party if the Plan or any amounts paid or payable thereunder become subject to the additional tax and penalties under Code Section 409A.

Overpayments, Offset and Clawback Provisions

The Company reserves the right to collect any overpayment of any MIP Award, regardless of reason, as soon as such overpayment is discovered. The Plan Administrator may, in its sole discretion, offset any amount payable under the MIP by any amount owed by a Participant to the Company; provided that such offsets may be applied to any amounts payable hereunder that are subject to Code Section 409A only if, and to the extent expressly permissible, under Code Section 409A.

Notwithstanding anything to the contrary in this Plan, subject to applicable law, in the event that the Plan Administrator determines that a Participant has engaged in Detrimental Conduct or Financial Misconduct (each as defined below), any outstanding MIP Awards for the Plan Year(s)

5

during which such Detrimental Conduct or Financial Misconduct occurred (or continued) shall be forfeited and any amounts relating to previously paid MIP Awards to the Participant for such Plan Year(s) shall be repaid to the Company, in each case as determined by the Plan Administrator in its discretion. For purposes of this Plan, “Detrimental Conduct” means (i) conduct which is injurious to the Company or its business or reputation, involving a material breach of Company policy, or applicable laws or regulations to which the Participant is subject, or an agreement between the Company and the Participant, or (ii) any other action (or failure to act) involving illegal acts, theft, fraud, intentional misconduct, or gross negligence on the part of the Participant, related to his or her position with the Company. For purposes of this Plan, “Financial Misconduct” means fraud, gross negligence or intentional or willful misconduct that contributes, directly or indirectly, to the Company’s financial or operational results that are used to determine the extent to which any MIP Award is payable under the Plan being misstated, regardless of whether the Company is required to prepare an accounting restatement of its consolidated financial statements, which is discovered during the relevant Plan Year or within three years thereafter.

Any recoupment under this Plan shall be in addition to any other remedies that may be available to the Company, including such remedies contained, without limitation, in the Company’s employment agreements or equity award agreements. Nothing in this Plan shall be viewed as limiting the right of the Company to recoup any MIP Award or payment under or as required by the applicable provisions of any law, rule or regulation (including, without limitation, Section 10D of Securities Exchange Act of 1934, as amended, or Section 304 of the Sarbanes-Oxley Act of 2002), or stock exchange listing requirement (or any future policy adopted by the Company pursuant to any such law, rule, regulation or requirement). Without limiting the generality of the foregoing, all payments under the Plan shall be subject to the Company’s Incentive Compensation Clawback Policy.

Plan Administration

The Plan shall be administered by (i) in respect of any Participant who participates in the MIP at the executive zone level (each, an “Executive Zone Officer”), the Committee, and (ii) in respect of any Participant who is not an Executive Zone Officer, a committee comprised of Masonite’s VP, Global Total Rewards, the SVP of Human Resources and the President & CEO, unless otherwise determined by the Committee (each or with the Committee, as applicable, the “Plan Administrator”).

The Plan Administrator will have the full power and authority to interpret, construe and administer the Plan and the related terms and conditions thereof, to prescribe operational rules and guidelines with respect to the Plan, and to make all other determinations deemed necessary or advisable in administering the Plan. The decisions, determinations and other actions of the Plan Administrator hereunder shall be final and binding on all Participants and other persons for all purposes.

Except as otherwise expressly provided in this Plan, the Plan Administrator will have the power and discretionary authority to (i) determine the employees who are selected to become Participants in the Plan; (ii) approve the performance measures and measurement criteria to be used with respect to each MIP Award payable under the Plan or any sub-plan thereof, (iii) determine the amount of a MIP Award, if any, to be paid to each Participant, (iv) interpret and administer, reconcile any inconsistency in, correct any defect in and/or supply any omission in the Plan and any MIP Award, (v) establish, amend, suspend, or waive any rules and regulations and appoint such agents as the Plan Administrator shall deem appropriate for the proper

6

administration of the Plan, (vi) administer, interpret and answer all questions which may arise under the Plan, and (vii) make any other determination and take any other action that the Plan Administrator deems necessary or desirable for the administration of the Plan or to comply with any applicable law. Without limiting the foregoing, the Plan Administrator reserves the right in its sole discretion to withhold or permit payment of a MIP Award in the case of certain changes in the employment status of a Participant as set forth herein.

Plan Amendment or Termination

The Plan may be amended, terminated, changed or altered at any time and for any reason as determined by the Committee. The Committee may, in its sole discretion, reduce or eliminate a MIP Award to any Participant at any time and for any reason.

No Right to Assign or Transfer

No MIP Award payable hereunder, nor any right or interest of a Participant in the MIP, shall be assignable or transferable, except in the event of the Participant’s death prior to any payout as so determined by the Plan Administrator in its sole discretion, in which case, payment will be made to the designated beneficiary elected by the Participant under the Company’s basic life insurance program or the Participant’s estate, as required by law. Any attempt to sell, assign, pledge or otherwise transfer the right to payment of any MIP Award from the MIP shall be void and have no effect.

Document Confidentiality

This document is proprietary and is not for use or disclosure outside of the Company. It represents the intellectual property and business strategy of Masonite, and it should be kept confidential.

No Right to Employment

The MIP does not create or modify any Participant’s at-will status and does not create a contract or guarantee of employment for any specified duration. Nothing contained in the MIP shall interfere with the right of the Company to dismiss or terminate the employment of any Participant at any time for any reason, with or without cause.

Income Tax Withholding

The Company shall have the right to deduct and withhold from all MIP Awards all federal, state and local taxes as may be required by applicable law.

Governing Law

The Plan shall be governed and construed in accordance with the laws of the State of Florida (regardless of the law that might otherwise govern under applicable Florida principles of conflict of laws).

MASONITE INTERNATIONAL CORPORATION

INCENTIVE COMPENSATION CLAWBACK POLICY

1.    Overview. The Board of Directors of Masonite International Corporation (the “Company”) is committed to promoting a culture that emphasizes integrity and accountability. As part of this commitment, the Human Resources and Compensation Committee of the Board of Directors of the Company (the “Committee”) has adopted this Incentive Compensation Clawback Policy (the “Policy”), which requires the recoupment of certain incentive-based compensation upon the occurrence of specified events. This Policy is designed to comply with Section 10D of the Exchange Act and the Listing Rules. Capitalized terms not otherwise defined within the Policy shall have the meanings assigned to such terms in Exhibit A attach hereto.

2.    Interpretation and Administration. The Committee shall have full authority to interpret and enforce this Policy. This Policy shall be interpreted in all respects to comply with the Listing Rules and any inconsistencies shall be treated as retroactively amended to be compliant with the Listing Rules. This Policy is intended to supplement any other clawback policies and procedures that the Company may have in place from time to time pursuant to other applicable laws, plans, policies or agreements.

3.    Covered Executive. The Policy applies to each current and former Executive Officer as determined by the Board, and in accordance with Section 10D of the Exchange Act and the Listing Standards, in addition to each current and former member of the Masonite Executive Leadership Team (“Covered Executive”).

4.    Accounting Restatement. In the event the Company is required to prepare a Restatement, the Committee will require reimbursement or forfeiture of certain Incentive Compensation Received, to the extent that any portion of such Incentive Compensation is (a) determined to have included Erroneously Awarded Compensation and (b)Received by the Executive Officer during the last three completed Fiscal Years or any applicable Transition Period immediately preceding the date the Company determines a Restatement is required (regardless of whether any such Restatement is actually filed) as set forth in the Listing Rules.

5.    Forms of Recovery. The Committee shall determine, in its sole discretion and in a manner that effectuates the purpose of the Listing Rules, the method(s) for recovering any Erroneously Awarded Compensation. Such recovery, in the case of a Restatement, will be made without regard to any individual knowledge or responsibility related to the Restatement. The Committee shall reasonably promptly take steps to recover such Erroneously Awarded Compensation, which may include, without limitation:

(a) require cash reimbursement;

(b) seek recovery or forfeiture of any gain realized on the vesting, exercise, settlement, sale, transfer or other disposition of any equity-based awards;

(c) offset the amount to be recouped from any compensation otherwise owed by the Company to the Covered Executive;

(d) cancel outstanding vested or unvested equity awards; or

(e) take any other remedial and recovery action permitted by law, as determined by the Committee. To the extent the Covered Executive refuses to pay to the Company an amount equal to the Erroneously Awarded Compensation, the Company shall have the right to sue for repayment and/or enforce the Covered Executive’s obligation to make payment through the reduction or cancellation of outstanding and future compensation. Any reduction, cancellation or forfeiture of any compensation shall be done in compliance with Section 409A of the Internal Revenue Code of 1986, as amended.

6.    Exceptions to the Recovery Requirement. Notwithstanding anything in this Policy to the contrary, Erroneously Awarded Compensation need not be recovered pursuant to this Policy if the Committee determines that recovery would be “impracticable” as a result of any of the following:

(a)    the direct expense paid to a third party to assist in enforcing the Policy would exceed the amount to be recovered; provided that, before concluding that it would be impracticable to recover any amount of Erroneously Awarded Compensation based on expense of enforcement, the Company must make a reasonable attempt to recover such Erroneously Awarded Compensation, document such reasonable attempt(s) to recover, and provide that documentation to The New York Stock Exchange (the “Exchange”);

(b)    recovery would violate home country law where that law was adopted prior to November 28, 2022; provided that, before concluding that it would be impracticable to recover any amount of Erroneously Awarded Compensation based on violation of home country law, the Company must obtain an opinion of home country counsel, acceptable to the Exchange, that recovery would result in such a violation, and must provide such opinion to the Exchange; or

(c)    recovery would likely cause an otherwise tax-qualified retirement plan (i.e., the Company’s sponsored 401(k) plan), under which benefits are broadly available to employees of the Company, to fail to meet the requirements of 26 U.S.C. 401(a)(13) or 26 U.S.C. 411(a) and the regulations thereunder. The Company’s non-qualified deferred compensation plans are not included in this exception to recovery.

7.    Committee Determination Final. Any determination by the Committee with respect to this Policy shall be final, conclusive and binding on all interested parties.

8.    No Indemnification. Notwithstanding the terms of any other policy, program, agreement or arrangement, in no event will the Company or any of its affiliates indemnify or reimburse a Covered Executive for any loss under this Policy and in no event will the Company or any of its affiliates pay premiums on any insurance policy that would cover a Covered Executive potential obligation with respect to Erroneously Awarded Compensation under this Policy.

9.    Other Claims and Rights. Nothing in this Policy shall be deemed to limit or restrict the Committee to pursue additional remedies or recoupment as required under the Company’s compensation plans, award agreements, employment agreements or similar agreements or the applicable provisions of any law, rule or regulation which may require or permit recoupment to a greater degree under

circumstances not set forth in this Policy (but without duplication as to any recoupment already made with respect to Erroneously Awarded Compensation pursuant to this Policy).

10.    Successors. The Policy shall be binding and enforceable against all Covered Executives notwithstanding any termination of a Covered Executive’s employment with the Company and its affiliates, in addition to their beneficiaries, heirs, executors, administrators or other legal representatives.

11.    Amendment. The Policy may be amended by the Committee from time to time, to the extent permitted under the Listing Rules.

12.    Governing Law. To the extent not preempted by U.S. federal law, this Policy will be governed by and construed in accordance with the laws of the State of Florida, without reference to principles of conflict of laws.

Adopted July 24, 2023
Effective October 2, 2023

Exhibit A

Defined Terms

“Erroneously Awarded Compensation” shall mean the amount of Incentive Compensation actually Received that exceeds the amount of Incentive Compensation that otherwise would have been Received had it been determined based on the restated amounts, and computed without regard to any taxes paid. For Incentive Compensation based on stock price or total shareholder return, where the amount of erroneously awarded Incentive Compensation is not subject to mathematical recalculation directly from the information in a Restatement:

(a)    The calculation of Erroneously Awarded Compensation shall be based on a reasonable estimate of the effect of the Restatement on the stock price or total shareholder return upon which the Incentive Compensation was Received; and

(b)    The Company shall maintain documentation of the determination of that reasonable estimate and provide such documentation to the Exchange.

“Exchange Act” shall mean Securities Exchange Act of 1934, as amended from time to time.

“Executive Officer” shall mean the Company’s “officers” as defined in Rule 16a-1 (i.e. Section 16 officers) of the Exchange Act which include the Company’s president, principal financial officer, principal accounting officer (or if there is no such accounting officer, the controller), any vice-president of the Company in charge of a principal business unit, division, or function (such as sales, administration, or finance), any other officer who performs a policy-making function, or any other person who performs similar policymaking functions for the Company. Executive officers of the Company’s parent(s) or subsidiaries shall be deemed executive officers of the Company if they perform such policy making functions for the Company.

“Financial Reporting Measures” shall mean measures that are determined and presented in accordance with the accounting principles used in preparing the Company’s financial statements, and any measures that are derived wholly or in part from such measures, including, without limitation, stock price and total shareholder return (in each case, regardless of whether such measures are presented within the Company’s financial statements or included in a filing with the Securities and Exchange Commission).

“Fiscal Year” shall mean the Company’s fiscal year; provided that a Transition Period between the last day of the Company’s previous fiscal year end and the first day of its new fiscal year that comprises a period of nine to 12 months will be deemed a completed fiscal year.

“Incentive Compensation” shall mean any compensation (whether cash or equity-based) that is granted, earned, or vested based wholly or in part upon the attainment of a Financial Reporting Measure, and may include, but shall not be limited to, performance bonuses and long-term incentive awards such as stock options, stock appreciation rights, restricted stock, restricted stock units, performance share units or other equity-based awards. For the avoidance of doubt, Incentive Compensation does not include base salaries, awards that vest exclusively upon completion of a specified employment period, without any performance condition, and bonus awards that are discretionary or based on subjective goals or goals unrelated to Financial Reporting Measures.Notwithstanding the foregoing, compensation amounts shall

not be considered “Incentive Compensation” for purposes of the Policy unless such compensation is Received (1) while the Company has a class of securities listed on a national securities exchange or a national securities association and (2) on or after October 2, 2023.

“Listing Rules” shall mean Section 303A.14 of the New York Stock Exchange Listed Company Manual, as such section may be amended from time to time.

“Masonite Executive Leadership Team” shall mean executive band officers who directly report to the Chief Executive Officer of the Company.

“Received.” Incentive Compensation is deemed “Received” in the Company’s fiscal period during which the Financial Reporting Measure specified in the Incentive Compensation award is attained, even if the payment or grant of the Incentive Compensation occurs after the end of that period.

“Restatement” shall mean an accounting restatement due to the material noncompliance of the Company with any financial reporting requirement under the securities laws, including any required accounting restatement to correct an error in previously issued financial statements that is material to the Company’s previously issued financial statements (commonly referred to as “Big R” restatements), or that would result in a material misstatement if the error were corrected in the current period or left uncorrected in the current period (commonly referred to as “little r” restatements).

“Transition Period” shall mean any transition period that results from a change in the Company’s Fiscal Year within or immediately following the three completed Fiscal Years immediately preceding the Company’s requirement to prepare a Restatement.

Business Overview and Significant Accounting Policies

Business Overview and Significant Accounting Policies

Unless we state otherwise or the context otherwise requires, references to "Masonite," "we," "our," "us" and the "Company" in these notes to the consolidated financial statements refer to Masonite International Corporation and its subsidiaries.

Description of Business

Masonite International Corporation is one of the largest manufacturers of doors in the world, with significant market share in both interior and exterior door products. Masonite operates 64 manufacturing locations in seven countries and sells doors to customers throughout the world, including the United States, Canada and the United Kingdom.

Our workforce includes over 10,000 employees and contract personnel in seven different countries. This includes approximately 2,200 unionized employees, approximately 85% of whom are located in North America and with the remainder in various foreign locations. Nine of our North American facilities have individual collective bargaining agreements, which are negotiated locally and the terms of which vary by location.

Basis of Presentation

We prepare these consolidated financial statements in accordance with accounting principles generally accepted in the United States of America ("GAAP"). These consolidated financial statements include the accounts of Masonite International Corporation, a company incorporated under the laws of British Columbia, and its subsidiaries, as of December 31, 2023, and January 1, 2023, and for the years ended December 31, 2023, January 1, 2023, and January 2, 2022.

Our fiscal year is the 52- or 53-week period ending on the Sunday closest to December 31. In a 52-week year, each fiscal quarter consists of 13 weeks. For ease of disclosure, the 13-week periods are referred to as three-month periods and the 52- or 53-week periods are referred to as years. Our 2020 fiscal year, which ended on January 3, 2021, contained 53 weeks of operating results, with the additional week occurring in the fourth quarter.

Changes in Accounting Standards and Policies

Adoption of Recent Accounting Pronouncements

In December 2021, the Financial Accounting Standards Board ("FASB") issued ASU 2021-10, "Government Assistance," which requires annual disclosures that increase the transparency of transactions involving government grants, including (1) the types of transactions, (2) the accounting for those transactions and (3) the effect of those transactions on an entity's financial statements. The guidance was effective for annual periods beginning after December 15, 2021, with early adoption permitted. We have adopted the new guidance as of January 3, 2022, the beginning of fiscal year 2022, and the adoption did not have a material impact on our financial statements or disclosures.

In October 2021, the FASB issued ASU 2021-08, "Accounting for Contract Assets and Contract Liabilities from Contracts with Customers," which clarifies that an acquirer of a business should recognize and measure contract assets and contract liabilities in a business combination in accordance with ASU 2014-09," Revenue from Contracts with Customers" as if the entity had originated the contracts. The guidance was effective for fiscal years beginning after December 15, 2022, with early application permitted. We have adopted the new guidance as of January 2, 2023, the beginning of fiscal year 2023, and the adoption did not have a material impact on our financial statements or disclosures.

Other Recent Accounting Pronouncements not yet Adopted

In December 2023, the FASB issued ASU 2023-09, "Income Taxes (Topic 740) - Improvements to Income Tax Disclosures," which requires public business entities to annually disclose specific categories in the rate reconciliation and provide additional information for reconciling items that meet a quantitative threshold. The guidance is effective for fiscal years beginning after December 15, 2024, with early application permitted. We did not early adopt and believe the adoption of this new guidance will not have a material impact on our financial statements.

In November 2023, the FASB issued ASU 2023-07, "Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures," which improves reportable segment disclosure requirements, primarily through enhanced disclosures about significant segment expenses. The guidance is effective for fiscal years beginning after December 15, 2023, with early application permitted. We did not early adopt and believe the adoption of this new guidance will not have a material impact on our financial statements.

Summary of Significant Accounting Policies

(a) Principles of consolidation:

These consolidated financial statements include the accounts of Masonite and our subsidiaries and the accounts of any variable interest entities for which we are the primary beneficiary. Intercompany accounts and transactions have been eliminated upon consolidation. The results of subsidiaries acquired during the periods presented are consolidated from their respective dates of acquisition using the acquisition method. Subsidiaries are prospectively deconsolidated as of the date we no longer have effective control of the entity.

(b) Translation of consolidated financial statements into U.S. dollars:

These consolidated financial statements are expressed in U.S. dollars. The accounts of the majority of our self-sustaining foreign operations are maintained in functional currencies other than the U.S. dollar. Assets and liabilities for these subsidiaries have been translated into U.S. dollars at the exchange rates prevailing at the end of the period and results of operations at the average exchange rates for the period. Unrealized exchange gains and losses arising from the translation of the financial statements of our non-U.S. functional currency operations are accumulated in the cumulative translation adjustments account in accumulated other comprehensive loss. For our foreign subsidiaries where the U.S. dollar is the functional currency, all foreign currency-denominated accounts are remeasured into U.S. dollars. Unrealized exchange gains and losses arising from remeasurements of foreign currency-denominated assets and liabilities are included within other (income) expense, net in the consolidated statements of income and comprehensive income. Gains and losses arising from international intercompany transactions that are of a long-term investment nature are reported in the same manner as translation gains and losses. Realized exchange gains and losses are included in net income for the periods presented.

(c) Cash and cash equivalents:

Cash includes cash equivalents which are short-term highly liquid investments with original maturities of three months or less.

(d) Restricted cash:

Restricted cash includes cash we have placed as collateral for standby letters of credit. The letters of credit guarantee payment to third parties in the event the company is in breach of contract terms as detailed in each letter of credit. As of December 31, 2023, and January 1, 2023, we had standby letters of credit totaling $2.0 million and $2.1 million, respectively. There were no amounts drawn upon these letters of credit as of December 31, 2023, or January 1, 2023.

(e) Accounts receivable:

Our customers are primarily retailers, distributors and contractors. We record an allowance for credit losses at the time that accounts receivable are initially recorded based on the historical write-off experience and the current economic environment as well as our expectations of future economic conditions. We reassess the allowance at each reporting date. When it becomes apparent, based on age or customer circumstances, that such amounts will not be collected, they are charged to the allowance. Payments subsequently received are credited to the credit loss expense account included within selling, general and administration expenses in the consolidated statements of income and comprehensive income. Generally, we do not require collateral for our accounts receivable.

(f) Inventories:

Raw materials, work in process and finished goods are valued at the lower of cost or net realizable value. Cost is determined on a first in, first out basis. In determining the net realizable value, we consider factors such as yield, turnover, expected future demand and past experience.

The cost of inventories includes all costs of purchase, costs of conversion and other costs incurred in bringing the inventories to their present location and condition. The costs of conversion of inventories include costs directly related to the units of production, such as direct labor. They also include a systematic allocation of fixed and variable production overheads that are incurred in converting raw materials into finished goods. Fixed production overheads are those indirect costs of production that remain relatively constant regardless of the volume of production, such as depreciation and maintenance of factory buildings and equipment, and the cost of factory management and administration. Variable production overheads are those indirect costs of production that vary directly, or nearly directly, with the volume of production, such as indirect materials and indirect labor.

To determine the cost of inventory, we allocate fixed expenses to the cost of production based on the normal capacity, which refers to a range of production levels and is considered the production expected to be achieved over a number of periods or seasons under normal circumstances, taking into account the loss of capacity resulting from planned maintenance. Fixed overhead costs allocated to each unit of production are not increased due to abnormally low production. Those excess costs are recognized as a current period expense. When a production facility is completely shut down temporarily, it is considered idle, and all related expenses are charged to cost of goods sold.

(g) Property, plant and equipment:

Property, plant and equipment are stated at cost. Depreciation is recorded based on the carrying values of buildings, machinery and equipment using the straight-line method over the estimated useful lives set forth as follows:

	Useful Life (Years)
Buildings	20 - 40
Machinery and equipment
Tooling	10 - 25
Machinery and equipment	5 - 25
Molds and dies	20 - 25
Office equipment, fixtures and fittings	3 - 10
Information technology systems	5 - 15

Improvements and major maintenance that extend the life of an asset are capitalized; other repairs and maintenance are expensed as incurred. When assets are retired or otherwise disposed, their carrying values and accumulated depreciation are removed from the accounts.

Property, plant and equipment are tested for impairment when events or changes in circumstances indicate that the carrying value of an asset or asset group may not be recoverable. An impairment loss is recognized when the carrying amount of an asset or asset group being tested for recoverability exceeds the sum of the undiscounted cash flows expected from its use and disposal. Impairments are measured as the amount by which the carrying amount of the asset or asset group exceeds its fair value, as determined using a discounted cash flows approach when quoted market prices are not available.

(h) Leases:

We determine if a contract is a lease at inception or upon acquisition and reevaluate each time a lease contract is amended or otherwise modified. A lease will be classified as an operating lease if it does not meet any of the criteria for a finance lease. Those criteria include the transfer of ownership of the underlying asset by the end of the lease term; an option to purchase the underlying asset that we would be reasonably certain to exercise; the lease term is for the major part of the remaining economic life of the underlying asset; the present value of the sum of the lease payments and any

residual value guaranteed by us that is not already reflected in the lease payments equals or exceeds substantially all of the fair value of the underlying asset or if the underlying asset is of such a specialized nature that it is expected to have no alternative use to the lessor at the end of the lease term.

The assets and liabilities relating to operating leases are included in operating lease right-of-use assets, accrued expenses, and long-term operating lease liabilities in our consolidated balance sheets. The assets and liabilities relating to finance leases are included in property, plant and equipment, net, accrued expenses and other liabilities in our consolidated balance sheets.

ROU assets represent our right to use an underlying asset for the lease term and lease liabilities represent our obligation to make lease payments arising from the lease. Operating lease ROU assets and liabilities are recognized at the respective lease commencement date based on the present value of lease payments over the expected lease term. Since our leases do not specify implicit discount rates, we use our incremental borrowing rate based on the information available at the commencement date in determining the present value of lease payments. The operating lease ROU asset also includes any initial direct costs and is adjusted for lease incentives and prepaid or accrued rent. The lease term begins on the date when the lessor makes the underlying asset available for use to us, and our expected lease terms include options to extend the lease when it is reasonably certain that we will exercise those options. Lease payments are recognized in the consolidated statements of income and comprehensive income on a straight-line basis over the expected lease term.

Leases with an initial term of 12 months or less are not recorded on the balance sheet, with the related lease expense recognized on a straight-line basis over the lease term. Lease and non-lease components of a contract are combined into a single lease component for accounting purposes.

Our operating leases include leases for real estate (including manufacturing sites, warehouses and offices) and machinery and equipment and our finance leases include leases for real estate. We have no material subleases. Certain of our operating leases contain provisions for renewal ranging from one to four options of one to ten years each.    

(i) Goodwill:

We use the acquisition method of accounting for all business combinations, and we evaluate all business combinations for intangible assets that should be recognized apart from goodwill. Goodwill adjustments are recorded for the effect on goodwill of changes to net assets acquired during the measurement period (up to one year from the date of acquisition) for 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.

Goodwill is not amortized, but instead is tested annually for impairment on the last day of fiscal November, or more frequently if events or changes in circumstances indicate the carrying amount may not be recoverable. The test for impairment is performed at the reporting unit level by comparing the reporting unit’s carrying amount to its fair value. Possible impairment in goodwill is first analyzed using qualitative factors such as macroeconomic and market conditions, changing costs and actual and projected performance, amongst others, to determine whether it is more likely than not that the book value of the reporting unit exceeds its fair value. If it is determined more likely than not that the book value exceeds fair value, a quantitative analysis is performed to test for impairment. When quantitative steps are determined necessary, the fair values of the reporting units are estimated through the use of discounted cash flow analysis and market multiples. If the carrying amount exceeds fair value, then goodwill is impaired. Any impairment in goodwill is measured as the excess of the carrying value of goodwill over the fair value.

When developing our discounted cash flow analyses, a number of assumptions and estimates are involved to forecast operating cash flows, including future net sales growth, EBITDA margin, benefits from restructuring initiatives, income tax rates, capital spending, business initiatives and working capital changes. These assumptions may vary significantly among the reporting units. Operating cash flow forecasts are based on operating plans for the early years and historical relationships and long-term economic outlooks for our industry in later years. The discount rate is estimated for each specific reporting unit. Due to the many variables inherent in the estimation of a reporting unit’s fair value and the relative size of our recorded goodwill, differences in assumptions may have a material effect on the results of our impairment analyses. In the year ended December 31, 2023, we recorded $33.1 million in goodwill impairment charges in our Europe reporting unit. There were no impairment charges recorded against goodwill in 2022. In 2021, we

recorded $59.5 million in impairment charges related to the Architectural reporting unit. See Note 14 for further information.

(j) Intangible assets:

Intangible assets with definite lives include customer relationships, patents, system software development and acquired trademarks and tradenames. Definite lived intangible assets are amortized over their estimated useful lives. Information pertaining to the estimated useful lives of intangible assets is as follows:

	Estimated Useful Life (Years)	Estimated Useful Life
Customer relationships	10 - 15	Over expected relationship period
Patents	10 - 12	Over expected useful life
System software development	5 - 15	Over expected useful life
Acquired trademarks and tradenames	2 - 10	Over expected useful life

Amortizable intangible assets are tested for impairment whenever events or changes in circumstances indicate that the carrying value may be greater than fair value. An impairment loss is recognized when the estimate of undiscounted future cash flows generated by such assets is less than the carrying amount. Measurement of the impairment loss is based on the fair value of the asset. Fair value is measured using discounted cash flows.

Indefinite lived intangible assets are not amortized, but instead are tested for impairment annually on the last day of fiscal November, or more frequently if events or circumstances indicate the carrying value may exceed the fair value.

(k) Income taxes:

As a multinational corporation, we are subject to taxation in many jurisdictions and the calculation of our tax liabilities involves dealing with inherent uncertainties in the application of complex tax laws and regulations in various taxing jurisdictions. We assess the income tax positions and record tax liabilities for all years subject to examination based upon our evaluation of the facts, circumstances and information available as of the reporting date. Our global structure required an assessment of the Company’s interpretation and application of tax laws in multiple jurisdictions including the income tax impact of the legal entity ownership structure and intercompany transactions.

We use the asset and liability method of accounting for income taxes. Under the asset and liability method, deferred tax assets and liabilities are recognized for the deferred tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities due to a change in tax rates is recognized in income in the period that includes the date of enactment. A valuation allowance is recorded to reduce deferred tax assets to an amount that is anticipated to be realized on a more likely than not basis.

We account for uncertain taxes in accordance with ASC 740, "Income Taxes." The initial benefit recognition model follows a two-step approach. First, we evaluate if the tax position is more likely than not of being sustained if audited based solely on the technical merits of the position. Second, we measure the appropriate amount of benefit to recognize. This is calculated as the largest amount of tax benefit that has a greater than 50% likelihood of ultimately being realized upon settlement. Subsequently at each reporting date, the largest amount that has a greater than 50% likelihood of ultimately being realized, based on information available at that date, will be measured and recognized.

We recognize interest and penalties related to unrecognized tax benefits within the income tax expense line in the consolidated statements of income and comprehensive income. Accrued interest and penalties are included within the related tax liability line in the consolidated balance sheets.

(l) Employee future benefits:

We maintain defined benefit pension plans. Benefits under the plans were frozen or curtailed at various times in the past. Earnings are charged with the cost of benefits earned by employees as services are rendered. The cost reflects management’s best estimates of the pension plans’ expected investment yields, wage and salary escalation, mortality of members, terminations and the ages at which members will retire. Changes in these assumptions could impact future pension expense. Service cost components are recognized within cost of goods sold and non-service cost components are recognized within other (income) expense, net in the consolidated statements of income and comprehensive income. The excess of the net actuarial gain (loss) over 10% of the greater of the benefit obligation or fair value of plan assets at the beginning of the year is amortized over the average remaining service lives of the members.

Assets are valued at fair value for the purpose of calculating the expected return on plan assets. Past service costs arising from plan amendments are amortized on a straight-line basis over the average remaining service period of employees active at the date of amendment.

When a restructuring of a benefit plan gives rise to both a curtailment and a settlement of obligations, the curtailment is accounted for prior to the settlement. Curtailment gains are offset against unrecognized losses and any excess gains and all curtailment losses are recorded in the period in which the curtailment occurs.

(m) Restructuring costs:

Restructuring costs include all salary-related severance benefits that are accrued and expensed when a restructuring plan has been put into place, the plan has received approval from the appropriate level of management and the benefit is probable and reasonably estimable. In addition to salary-related costs, we incur other restructuring costs when facilities are closed or capacity is realigned within the organization. Upon termination of a contract we record liabilities and expenses pursuant to the terms of the relevant agreement. For non-contractual restructuring activities, liabilities and expenses are measured and recorded at fair value in the period in which they are incurred.

Restructuring-related costs are presented separately in the consolidated statements of income and comprehensive income whereas non-restructuring severance benefits are charged to cost of goods sold or selling, general and administration expense depending on the nature of the job responsibilities.

(n) Financial instruments:

We have applied a framework consistent with ASC 820, "Fair Value Measurement and Disclosure," and have disclosed all financial assets and liabilities measured at fair value and non-financial assets and liabilities measured at fair value on a non-recurring basis (at least annually).

We classify and disclose assets and liabilities carried at fair value in one of the following three categories:

        Level 1: Quoted market prices in active markets for identical assets or liabilities.

        Level 2: Observable market based inputs or unobservable inputs that are corroborated by market data.

        Level 3: Unobservable inputs that are not corroborated by market data.

The estimated fair value of a financial instrument is the amount at which the instrument could be exchanged in a current transaction between willing parties, other than a forced or liquidation sale. These estimates, although based on the relevant market information about the financial instrument, are subjective in nature and, therefore, cannot be determined with precision. Changes in assumptions could significantly affect the estimates.

(o) Share based compensation expense:

We have a share based compensation plan, which is described in detail in Note 12. We apply the fair value method of accounting using comprehensive valuation models, including the Black-Scholes-Merton option pricing model and the Monte Carlo simulation method, to determine the compensation expense.

(p) Revenue recognition:

Revenue from the sale of products is recognized when control of the promised goods is transferred to our customers based on the agreed-upon shipping terms, in an amount that reflects the consideration to which we expect to be entitled in exchange for those goods or services. Volume rebates, expected returns, discounts and other incentives to customers are considered variable consideration and we estimate these amounts based on the expected amount to be provided to customers and reduce the revenues we recognize accordingly. Sales taxes and value added taxes assessed by governmental entities are excluded from the measurement of consideration expected to be received. Shipping and handling costs incurred after a customer has taken possession of our goods are treated as a fulfillment cost and are not considered a separate performance obligation. Shipping and other transportation costs charged to customers are recorded in both revenues and cost of goods sold in the consolidated statements of income and comprehensive income.

(q) Product warranties:

We warrant certain qualitative attributes of our door products. We have recorded provisions for estimated warranty and related costs within accrued expenses on the consolidated balance sheets, based on historical experience and we periodically adjust these provisions to reflect actual experience. The rollforward of our warranty provision is as follows for the periods indicated:

	Year Ended
(In thousands)	December 31, 2023		January 1, 2023		January 2, 2022
Balance at beginning of period	$	3,881	$	4,015	$	4,635
Additions charged to expense	4,792		5,085		4,646
Deductions	(4,436)		(5,219)		(5,266)
Balance at end of period	$	4,237	$	3,881	$	4,015

(r) Vendor rebates:

We account for cash consideration received from a vendor as a reduction of cost of goods sold and inventory, in the consolidated statements of income and comprehensive income and consolidated balance sheets, respectively. The cash consideration received represents agreed-upon vendor rebates that are earned in the normal course of operations.

(s) Advertising costs:

We recognize advertising costs as they are incurred. Advertising costs incurred primarily relate to tradeshows and are included within selling, general and administration expense in the consolidated statements of income and comprehensive income. Advertising costs were $20.0 million, $16.9 million and $14.2 million in the years ended December 31, 2023, January 1, 2023, and January 2, 2022, respectively.

(t) Research and development costs:

We recognize research and development costs as they are incurred. Research and development costs incurred primarily relate to the development of new products and the improvement of manufacturing processes, and are primarily included within cost of goods sold in the consolidated statements of income and comprehensive income. These costs exclude the significant investments in other areas such as advanced automation. Research and development costs were $27.8 million, $21.2 million and $18.4 million in the years ended December 31, 2023, January 1, 2023, and January 2, 2022, respectively.

(u) Insurance losses and proceeds:

All involuntary conversions of property, plant and equipment are recorded as losses within loss (gain) on disposal of property, plant and equipment, which is included within selling, general and administration expense in the consolidated statements of income and comprehensive income and as reductions to property, plant and equipment in the consolidated balance sheets. Any subsequent proceeds received for insured losses of property, plant and equipment are also recorded as gains within loss (gain) on disposal of property, plant and equipment, and are classified as cash flows

from investing activities in the consolidated statements of cash flows in the period in which the cash is received. Proceeds received for business interruption recoveries are recorded as a reduction to selling, general and administration expense in the consolidated statements of income and comprehensive income and are classified as cash flows from operating activities in the consolidated statements of cash flows in the period in which an acknowledgment from the insurance carrier of settlement or partial settlement of a non-refundable nature has been presented to us.

(v) Equity investments:

We account for investments in affiliates of between 20% and 50% ownership, over which we have significant influence, using the equity method. We record our share of earnings of the affiliate within other income, net of expense, in the consolidated statements of income and comprehensive income and dividends as a reduction of the investment in the affiliate in the consolidated balance sheets when declared.

(w) Segment reporting:

Our reportable segments are organized and managed principally by end market: North American Residential, Europe and Architectural. The Corporate & Other category includes unallocated corporate costs and the results of immaterial operating segments that were not aggregated into any reportable segment. In addition to similar economic characteristics we also consider the following factors in determining the reportable segments: the nature of business activities, the management structure directly accountable to our chief operating decision maker for operating and administrative activities, availability of discrete financial information and information presented to the Board of Directors and investors.

(x) Use of estimates:

The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions which affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of the date of the consolidated financial statements and the reported amounts of net sales and expenses during the reporting periods. During 2023, there were no material changes in the methods or policies used to establish estimates and assumptions. Actual results may differ from our estimates.

Acquisitions and Divestitures

Acquisitions

Fleetwood

On October 19, 2023, the Company completed the acquisition of all of the issued and outstanding limited liability company interests of Fleetwood Aluminum Products, LLC (“Fleetwood”). The total consideration for this acquisition amounted to approximately $279.1 million, inclusive of $26.2 million designated for potential purchase price adjustments and indemnification claims and which is currently held in an escrow account controlled by a third party. The total consideration was funded with a combination of cash on hand and borrowings under the ABL Facility. Fleetwood is a leading designer and manufacturer of premium, aluminum-framed glass door and window solutions for luxury homes. Their products include multi-slide and pocket glass patio doors, pivot and hinged glass entry doors and folding glass door wall systems, as well as accompanying premium window products. The acquisition aligns with the Doors That Do MoreTM strategy focused on bringing differentiated door systems to the residential market.

The Company has accounted for the acquisition as a business combination and allocated the preliminary estimated purchase price to the estimated fair values of assets acquired and liabilities assumed utilizing various valuation methods including replacement cost, market values and the income approach. The Company has not yet completed its evaluation and determination of the value of certain assets acquired and liabilities assumed, primarily involving (i) certain historical information used in the final valuation of intangible assets, and (ii) the final assessment and valuation of inventory and deferred income taxes, which could impact goodwill during the measurement period. The $73.5 million excess purchase price over the fair value of tangible and intangible assets acquired was allocated to goodwill. Goodwill represents the estimated future economic benefits arising from other assets acquired that could not be individually identified and separately recognized, such as the delivery of luxury products, which supports our Doors That Do MoreTM strategy. This goodwill is deductible for tax purposes and relates to the North American Residential segment.

The allocation of the purchase price to assets acquired and liabilities assumed is as follows:

(In thousands)	Initial Purchase Price Allocation
Cash acquired	$	5,169
Accounts receivable, net	5,584
Inventories, net	39,248
Prepaid expenses and other	957
Property, plant and equipment, net	8,072
Right-of-use asset	16,009
Intangible assets	163,900
Total assets acquired	238,939
Accounts payable and accrued expenses	(20,773)
Operating lease liability	(12,546)
Total liabilities assumed	(33,319)
Goodwill	73,464
Total purchase price	$	279,084

The fair values of intangible assets acquired are based on management's estimates and assumptions including the income approach, the cost approach and the market approach. Customer relationships and patents acquired are not expected to have any residual value. The gross contractual value of acquired trade receivables was $5.6 million.

Endura

On January 3, 2023, we completed the acquisition of 100% of the outstanding equity of EPI Holdings, Inc. ("Endura"), for total consideration of approximately $403.3 million, including an $18.0 million holdback which is payable 24 months after the acquisition date and was recorded in the consolidated balance sheets as a component of other liabilities. The total consideration was funded with borrowings under our Term Loan Facility and ABL Facility. Endura is a leading innovator and manufacturer of high-performance door frames and door system components in the United States. Endura’s product offerings include engineered frames, self-adjusting sill systems, weather sealing, multi-point locks and installation accessories used by builders and contractors in residential new construction as well as repair and remodeling applications. The acquisition is intended to accelerate our Doors That Do MoreTM strategy and maximize our growth potential. The $181.2 million excess purchase price over the fair value of tangible and intangible assets acquired was allocated to goodwill. The goodwill principally represents anticipated synergies to be gained from the integration into our existing business and acquisition of the assembled workforce. This goodwill is not deductible for tax purposes and relates to the North American Residential segment.

The Company has accounted for the acquisition as a business combination and allocated the estimated purchase price to the estimated fair values of assets acquired and liabilities assumed utilizing various valuation methods including replacement cost, market values and the income approach.

The allocation of the purchase price to assets acquired and liabilities assumed is as follows:

(In thousands)	Initial Purchase Price Allocation		Measurement Period Adjustments		Purchase Price Allocation

The fair values of intangible assets acquired are based on management's estimates and assumptions including the income approach, the cost approach and the market approach. The intangible assets acquired are not expected to have any residual value. The gross contractual value of acquired trade receivables was $8.3 million.

Pro Forma Information

The following unaudited pro forma financial information represents the consolidated financial information as if the acquisitions had been included in our consolidated results beginning on the first day of the fiscal year prior to the respective acquisition dates. The pro forma results have been calculated after adjusting the results of the acquired entities to remove intercompany transactions and to reflect the additional depreciation, amortization and interest expense that would have been charged assuming the fair value adjustments to property, plant and equipment and intangible assets and the additional debt incurred to fund the acquisition had been applied on the first day of the fiscal year prior to the respective acquisition date, together with the consequential tax effects. The pro forma results do not reflect any cost savings, operating synergies or revenue enhancements that the combined companies may achieve as a result of the acquisition; the costs to combine the companies' operations; or the costs necessary to achieve these costs savings, operating synergies and revenue enhancements. As a result, the pro forma information below does not purport to represent actual results had the acquisition been consummated on the date indicated and it is not necessarily indicative of future results of operations.

Divestitures

As previously disclosed, we are actively reviewing strategic alternatives for our Architectural segment, including a potential sale of some or all of the business. There can be no assurance that a potential transaction will be consummated or on what terms. The Arrangement Agreement with Owens Corning restricts our ability to dispose of certain businesses, properties or assets of the Company without Owens Corning’s prior consent. If a transaction is

consummated, depending on the sale price, we could incur an impairment charge related to the book value of the segment's assets. This charge could be material.

During the fourth quarter of 2022, we completed the liquidation of our legal entity in Turkey. As a result, we recognized $0.9 million in loss on disposal of subsidiaries. The total charge consists of $0.7 million relating to the recognition of cumulative translation adjustment out of accumulated other comprehensive loss and $0.2 million relating to the write-off of net assets.

On June 14, 2021, we completed the sale of all the capital stock of our Czech business for consideration of $7.0 million, net of cash disposed. The divestiture of this business resulted in a loss on disposal of subsidiaries of $8.6 million, which was recognized in the second quarter of 2021 in the Europe segment. The total charge consisted of $5.1 million relating to the write-off of the net assets sold and other professional fees and $3.5 million relating to the recognition of the cumulative translation adjustment out of accumulated other comprehensive loss.

Accounts Receivable

Our customers consist mainly of retailers, distributors and contractors. Our ten largest customers accounted for 65.2% and 62.3% of total accounts receivable as of December 31, 2023, and January 1, 2023, respectively. Our largest customer, The Home Depot, Inc. accounted for more than 10% of the consolidated gross accounts receivable balance as of December 31, 2023, and January 1, 2023. In addition, Lowe's Companies, Inc. accounted for more than 10% of the consolidated gross accounts receivable balance as of December 31, 2023. No other individual customer accounted for greater than 10% of the consolidated gross accounts receivable balance at either December 31, 2023, or January 1, 2023.

The changes in the allowance for doubtful accounts were as follows for the periods indicated:

Deductions	(428)		(669)		(964)
Balance at end of period	$	3,077	$	2,480	$	2,087

We maintain an accounts receivable sales program with a third party (the "AR Sales Program"). Under the AR Sales Program, we can transfer ownership of eligible trade accounts receivable of certain customers. Receivables are sold outright to a third party who assumes the full risk of collection, without recourse to us in the event of a loss. Transfers of receivables under this AR Sales Program are accounted for as sales. Proceeds from the transfers reflect the face value of the accounts receivable less a discount. Receivables sold under the AR Sales Program are excluded from trade accounts receivable in the consolidated balance sheets and are included in cash flows from operating activities in the consolidated statements of cash flows. The discounts on the sales of trade accounts receivable sold under the AR Sales Program were not material for any of the periods presented and were recorded in selling, general and administration expense within the consolidated statements of income and comprehensive income.

In most countries we pay and collect Value Added Tax ("VAT") when procuring goods and services within the normal course of business. VAT receivables are established in jurisdictions where VAT paid exceeds VAT collected and are recoverable through the filing of refund claims.

Certain wood moldings and millwork products being imported into the U.S. are subject to import tariffs. Tariff deposits are paid to the government and are recoverable through an assessment process.

Within fiscal year 2023, the Company completed the acquisitions of Fleetwood and Endura. As part of these acquisitions, we recognized $254.6 million in combined goodwill. See Note 2. Acquisitions and Divestitures for further information.

We evaluate goodwill and indefinite-lived intangible assets for impairment annually during the fourth quarter and at interim dates if indicators of impairment exist. Goodwill is assessed for impairment at the reporting unit level.

Gross goodwill before cumulative impairment charges and foreign exchange fluctuations in the Europe reporting unit was $60.0 million as of the beginning of 2023. During the year ended December 31, 2023, we recognized an asset impairment charge of $33.2 million related to a goodwill impairment charge due to weakening consumer confidence in the United Kingdom that continues to affect demand in the repair and remodel market, negative impacts from rising energy and fuel costs, partly attributable to geopolitical conflicts, as well as rising costs for raw materials and material supply constraints. The charge represents the amount by which the carrying value of the Europe reporting unit exceeded its fair value, and was recorded in the consolidated statements of income and comprehensive income and reduced the goodwill balance in the Europe reporting unit from $60.0 million to $26.8 million, excluding foreign exchange fluctuations. See Note 14 for further information.

Gross goodwill before cumulative impairment charges in the Architectural reporting unit was $59.5 million as of the beginning of 2021. As a result of manufacturing constraints in the Architectural reporting unit due to COVID-19 related absenteeism, material availability and production challenges, a goodwill impairment charge of $59.5 million was recorded to selling, general and administration expenses in 2021. The charge represents the amount by which the carrying value of the Architectural reporting unit exceeded its fair value and reduced the goodwill balance in the Architectural reporting unit from $59.5 million to zero. See Note 14 for further information.

Debt issuance costs incurred in connection with the 2030 Notes and the 2028 Notes were capitalized as a reduction to the carrying value of debt and are being accreted to interest expense over their respective terms. Additionally, we pay interest on any outstanding principal under our Term Loan Facility and ABL Facility, each as defined below, and we are required to pay a commitment fee for unutilized commitments under the ABL Facility, both of which are recorded in interest expense as incurred.

3.50% Senior Notes due 2030

On July 26, 2021, we issued $375.0 million aggregate principal senior unsecured notes (the "2030 Notes"). The 2030 Notes were issued in a private placement for resale to qualified institutional buyers pursuant to Rule 144A of the Securities Act of 1933, as amended (the "Securities Act"), and to buyers outside of the United States pursuant to Regulation S under the Securities Act. The 2030 Notes bear interest at 3.50% per annum, payable in cash semiannually in arrears on February 15 and August 15 of each year and the principal is due February 15, 2030. The 2030 Notes were issued at par. We received net proceeds of $370.3 million after deducting $4.7 million of debt issuance costs. The debt issuance costs were capitalized as a reduction to the carrying value of debt and are being accreted to interest expense over the term of the 2030 Notes using the effective interest method. The net proceeds from the issuance of the 2030 Notes were used to redeem the remaining $300.0 million aggregate principal amount of the 2026 Notes (as described below), including the payment of related premiums, fees and expenses, with the balance of the proceeds available for general corporate purposes.

Obligations under the 2030 Notes are fully and unconditionally guaranteed, jointly and severally, on a senior unsecured basis, by certain of our directly or indirectly wholly-owned subsidiaries. We may redeem the 2030 Notes, in whole or in part, at any time, at the applicable redemption prices specified under the indenture governing the 2030 Notes, plus accrued and unpaid interest, if any, to the date of redemption. If we experience certain changes of control, we must offer to repurchase all of the 2030 Notes at a purchase price of 101.00% of their principal amount, plus accrued and unpaid interest, if any, to, but excluding, the repurchase date.

The indenture governing the 2030 Notes contains limited covenants that, among other things, limit our ability and the ability of our subsidiaries to (i) incur certain secured debt, (ii) engage in certain sale and leaseback transactions and (iii) merge or consolidate with other entities. The foregoing limitations are subject to exceptions as set forth in the indenture governing the 2030 Notes. The indenture governing the 2030 Notes contains customary events of default (subject to certain cases to customary grace and cure periods). As of December 31, 2023, we were in compliance with all covenants under the indenture governing the 2030 Notes.

5.375% Senior Notes due 2028

On July 25, 2019, we issued $500.0 million aggregate principal senior unsecured notes (the "2028 Notes"). The 2028 Notes were issued in a private placement for resale to qualified institutional buyers pursuant to Rule 144A under the Securities Act, and to buyers outside of the United States pursuant to Regulation S under the Securities Act. The 2028 Notes were issued without registration rights and are not listed on any securities exchange. The 2028 Notes bear interest at 5.375% per annum, payable in cash semiannually in arrears on February 1 and August 1 of each year and the

principal is due February 1, 2028. The 2028 notes were issued at par. We received net proceeds of $493.3 million after deducting $6.7 million of debt issuance costs. The debt issuance costs were capitalized as a reduction to the carrying value of debt and are being accreted to interest expense over the term of the 2028 Notes using the effective interest method. The net proceeds from issuance of the 2028 Notes, together with available cash balances, were used to redeem the remaining $500.0 million aggregate principal amount of similar senior unsecured notes.

Obligations under the 2028 Notes are fully and unconditionally guaranteed, jointly and severally, on a senior unsecured basis, by certain of our directly or indirectly wholly-owned subsidiaries. We may redeem the 2028 Notes, in whole or in part, at any time on or after February 1, 2023, at the applicable redemption prices specified under the indenture governing the 2028 Notes, plus accrued and unpaid interest, if any, to the date of redemption. If we experience certain changes of control or consummate certain asset sales and do not reinvest the net proceeds, we must offer to repurchase all of the 2028 Notes at a purchase price of 101.00% (in the case of changes in control) or 100.00% (in the case of asset sales) of their principal amount, plus accrued and unpaid interest, if any, to, but excluding, the repurchase date.

The indenture governing the 2028 Notes contains restrictive covenants that, among other things, limit our ability and the ability of our subsidiaries to: (i) incur additional debt and issue disqualified or preferred stock, (ii) make restricted payments, (iii) sell assets, (iv) create or permit restrictions on the ability of our restricted subsidiaries to pay dividends or make other distributions to the parent company, (v) create or incur certain liens, (vi) enter into sale and leaseback transactions, (vii) merge or consolidate with other entities and (viii) enter into transactions with affiliates. The foregoing limitations are subject to exceptions as set forth in the indenture governing the 2028 Notes. In addition, if in the future the 2028 Notes have an investment grade rating from at least two nationally recognized statistical rating organizations, certain of these covenants will be terminated. The indenture governing the 2028 Notes contains customary events of default (subject in certain cases to customary grace and cure periods). As of December 31, 2023, we were in compliance with all covenants under the indenture governing the 2028 Notes.

5.750% Senior Notes due 2026

On August 27, 2018, we issued $300.0 million aggregate principal senior unsecured notes (the "2026 Notes"). The 2026 Notes were issued in a private placement for resale to qualified institutional buyers pursuant to Rule 144A under the Securities Act, and to buyers outside of the United States pursuant to Regulation S under the Securities Act. The 2026 Notes were issued without registration rights and are not listed on any securities exchange. The 2026 Notes bore interest at 5.75% per annum, payable in cash semiannually in arrears on March 15 and September 15 of each year and were originally due September 15, 2026. The 2026 notes were issued at par. We received net proceeds of $295.7 million after deducting $4.3 million of debt issuance costs. The debt issuance costs were capitalized as a reduction to the carrying value of debt and were accreted to interest expense over the term of the 2026 Notes using the effective interest method.

Subsequent to the closing of the 2030 Notes offering, the 2026 Notes were redeemed, and the notes were considered extinguished as of July 26, 2021. Under the terms of the indenture governing the 2026 Notes, we paid the applicable premium of $10.8 million. Additionally, the unamortized debt issuance costs of $2.8 million relating to the 2026 Notes were written off in conjunction with the extinguishment of the 2026 Notes. The resulting loss on extinguishment of debt was $13.6 million and was recorded as part of income from continuing operations before income tax expense in the condensed consolidated statements of income and comprehensive income in 2021. Additionally, the cash payment of interest accrued was accelerated to the redemption date.

Term Loan Facility

On December 13, 2022, we and certain of our subsidiaries entered into a new delayed-draw term loan credit agreement (the "Term Loan Credit Agreement") maturing on December 12, 2027 (the "Term Loan Maturity Date"). The Term Loan Credit Agreement provides for a senior secured five-year delayed-draw term loan facility of $250.0 million (the "Term Loan Facility"). Loans under the Term Loan Facility (the "Term Loans") will bear interest at a rate equal to, at our option, (1) the Adjusted Term SOFR Rate (as defined in the Term Loan Credit Agreement) plus an applicable margin of 2.25% or (2) an alternate base rate equal to the greatest of (i) the "Prime Rate" in the U.S. last quoted by The Wall Street Journal, (ii) 0.50% above the greater of the federal funds rate and the rate comprised of both overnight federal funds and overnight eurodollar transactions denominated in Dollars, (iii) 1.00% above the Adjusted Term SOFR

Rate for a one month interest period and (iv) 1.00%, plus, in each case, an applicable margin of 1.25%, subject to, in each of cases (1) and (2), an agreed interest rate floor. The Term Loans are repayable in equal quarterly installments for an annual aggregate amortization payment equal to 15% of the aggregate principal amount of the Term Loans, with the balance of the principal being due on the Term Loan Maturity Date.

The Term Loan Credit Agreement also includes a quarterly ticking fee of 25 basis points per annum payable to the lenders under the Term Loan Facility beginning on January 3, 2023 (the "Closing Date") in respect of the unutilized commitments thereunder. As a result of the incurrence of the Term Loans on the Closing Date such ticking fees were not (and shall not be) payable to the Lenders.

Obligations under the Term Loan Credit Agreement are fully and unconditionally guaranteed, jointly and severally, by us and by certain of our directly or indirectly wholly-owned subsidiaries organized in the United States and are secured by the equity in, and substantially all the assets of, such subsidiaries. The Term Loans were funded in an amount of $250.0 million and applied to finance a portion of the consideration payable in connection with the consummation of the Endura acquisition on January 3, 2023.

The Term Loan Credit Agreement contains restrictive covenants that, among other things, limit our ability and the ability of our subsidiaries to: (i) pay dividends on our common shares and make other restricted payments, (ii) make investments and acquisitions, (iii) engage in transactions with our affiliates, (iv) sell assets, (v) merge, (vi) incur additional debt and (vii) create liens. The Term Loan Credit Agreement includes certain exceptions and exemptions under the restricted payment, investment, dispositions, liens and indebtedness covenants.

The Term Loan Credit Agreement requires us to maintain at all times a total leverage ratio of no more than 4.50:1.00. The Term Loan Credit Agreement contains change of control provisions and certain customary affirmative covenants and events of default. As of December 31, 2023, we were in compliance with all covenants under the credit agreement governing the Term Loan Facility and there were no amounts outstanding.

ABL Facility

On January 31, 2019, we and certain of our subsidiaries entered into a $250.0 million asset-based revolving credit facility (the "ABL Facility") maturing on January 31, 2024, which replaced the previous facility. On October 28, 2022, we and certain of our subsidiaries entered into an amendment which, among other things, (i) increased the revolving credit commitments available thereunder by $100.0 million to an aggregate amount of $350.0 million and (ii) replaced the LIBOR-based interest rate applicable to borrowings thereunder in U.S. dollars with an interest rate based on the sum of (x) a "Term SOFR" rate published by the CME Group Benchmark Administration Limited (CBA) plus (y) 10 basis points ("Adjusted Term SOFR"). Additionally, on December 12, 2022, we entered into an amendment to the ABL Facility, which, among other things, extended the maturity of the ABL Facility from January 31, 2024 to December 12, 2027. The terms of the ABL Facility remained otherwise substantially unchanged. Obligations under the ABL Facility are secured by a first priority security interest in such accounts receivable, inventory and other related assets of Masonite and our subsidiaries. In addition, obligations under the ABL Facility are fully and unconditionally guaranteed, jointly and severally, on a senior secured basis, by certain of our directly or indirectly wholly-owned subsidiaries. 

Borrowings under the ABL Facility bear interest at a rate equal to, at our option, (i) the United States, Canadian or United Kingdom Base Rate (each as defined in the credit agreement relating to the ABL Facility, the "Amended and Restated Credit Agreement") plus a margin ranging from 0.25% to 0.50% per annum, or (ii) the Adjusted Term SOFR or BA Rate (each as defined in the Amended and Restated Credit Agreement), plus a margin ranging from 1.25% to 1.50% per annum. In addition to paying interest on any outstanding principal under the ABL Facility, a commitment fee is payable on the undrawn portion of the ABL Facility in an amount equal to 0.25% per annum of the average daily balance of unused commitments during each calendar quarter.

The ABL Facility contains various customary representations, warranties and covenants by us that, among other things, and subject to certain exceptions, restrict Masonite's ability and the ability of our subsidiaries to: (i) pay dividends on our common shares and make other restricted payments, (ii) make investments and acquisitions, (iii) engage in transactions with our affiliates, (iv) sell assets, (v) merge and (vi) create liens. The ABL Facility, among other things, (i) permits us to incur unlimited unsecured debt as long as such debt does not contain covenants or default provisions that are more restrictive than those contained in the ABL Facility, (ii) permits us to incur debt as long as the pro forma

secured leverage ratio is less than 4.5 to 1.0, and (iii) adds certain additional exceptions and exemptions under the restricted payment, investment and indebtedness covenants (including increasing the amount of certain debt permitted to be incurred under an existing exception). As of December 31, 2023, we were in compliance with all covenants under the credit agreement governing the ABL Facility. We had availability of $273.6 million under our ABL Facility and there were no amounts outstanding as of December 31, 2023.

Commitments and Contingencies

Commitments and Contingencies

We may become involved from time-to-time in litigation and regulatory compliance matters incidental to our business, including employment and wage and hour claims, antitrust, tax, product liability, environmental, health and safety, commercial disputes, intellectual property, contracts and other matters arising out of the normal conduct of our business. Since litigation is inherently unpredictable and unfavorable resolutions can occur, assessing contingencies is highly subjective and requires judgments about future events. We regularly review and accrue for contingencies related to litigation and regulatory compliance matters, if it is probable that a liability has been incurred and the amount of the loss can be reasonably estimated. Based on current information, in the opinion of management, the ultimate resolution of these matters, individually or in the aggregate, will not have a material adverse effect on our financial condition, results of operations or cash flows.

Antitrust Class Action Proceedings - Canada

On May 19, 2020, an intended class proceeding was commenced in the Province of Québec, Canada naming as defendants Masonite Corporation, Corporation Internationale Masonite, JELD-WEN, Inc., JELD-WEN Holding, Inc. and JELD-WEN of Canada, Ltd. The plaintiff alleges that the Masonite and JELD-WEN defendants engaged in anticompetitive conduct, including price-fixing involving interior molded doors. The intended class proceeding seeks damages, punitive damages, and other relief. On December 22, 2020, the parties filed a motion with the court seeking to stay the proceeding.

On October 2, 2020, an intended class proceeding was commenced in the Federal Court of Canada naming as defendants Masonite International Corporation, Masonite Corporation, JELD-WEN, Inc., JELD-WEN Holding, Inc. and JELD-WEN of Canada, Ltd. The plaintiff alleges that the Masonite and JELD-WEN defendants engaged in anticompetitive conduct, including price-fixing involving interior molded doors. The intended class proceeding seeks damages, punitive damages, and other relief. The plaintiff served its certification record on March 31, 2021.

On November 3, 2023, the Company entered into a preliminary settlement agreement with the plaintiff class that would result in the resolution of all the plaintiffs’ underlying claims and lawsuits in exchange for a payment by the Company of approximately $0.9 million. As a result, for the year ended December 31, 2023, we paid approximately $0.9 million and recorded a charge in selling, general and administrative expense in the condensed consolidated

statement of income and comprehensive income in connection with this matter. The preliminary settlement agreement is subject to court approval. A settlement approval hearing date has not yet been set.

Revenue from Contract with Customer [Abstract]

Revenues

Revenues

We derive our revenues primarily from the manufacture and delivery of doors and door components as performance obligations that arise from our contracts with customers are satisfied. Materially all of our revenues are generated from contracts with customers and the nature, timing and any uncertainty in the recognition of revenues are not affected by the type of good, customer or geographical region to which the performance obligation relates. Our contracts with our customers are generally in the form of purchase orders and the performance obligation arises upon receipt of the purchase order and agreement upon the transaction price. The performance obligations are satisfied at a point in time when control of the promised goods is transferred to the customer and payment terms vary from customer to customer. Payment terms are short-term, are customary for our industry and in some cases, early payment incentives are offered.

The transaction price recognized as revenue and accounts receivable is determined based upon a number of estimates, including:

•Incentive-based volume rebates, which are based on individual rebate agreements with our customers, as well as historical and expected performance of each individual customer,

•Estimated sales returns, which are based on historical returns as a percentage of revenues, and

•Adjustments for early payment discounts offered by us.

Contract assets are represented by our trade accounts receivable balances on the consolidated balance sheets, and are described in Note 3. Accounts Receivable. There were no other material contract assets or liabilities as of December 31, 2023, or January 1, 2023. Our warranties are assurance-type warranties and do not represent separate performance obligations to our customers. There were no material impairment losses related to contract assets during the years ended December 31, 2023, January 1, 2023, or January 2, 2022.

Share Based Compensation Plans

Share-Based Payment Arrangement [Abstract]

Share Based Compensation Plans

Share Based Compensation Plans

Share based compensation expense was $23.6 million, $21.8 million and $16.0 million for the years ended December 31, 2023, January 1, 2023, and January 2, 2022, respectively. As of December 31, 2023, the total remaining unrecognized compensation expense related to share based compensation amounted to $24.8 million, which will be amortized over the weighted average remaining requisite service period of 1.5 years. Share based compensation expense is recognized using a graded-method approach, or to a lesser extent a straight-line approach, depending on the terms of the individual award, and is classified within selling, general and administration expenses in the consolidated statements of income and comprehensive income. All forfeitures are accounted for as they occur. All share based awards are settled through issuance of new shares of our common stock. The share based award agreements contain restrictions on sale or transfer other than in limited circumstances. All other transfers would cause the share based awards to become null and void.

Equity Incentive Plan

On March 10, 2021, the Board of Directors adopted the Masonite International Corporation 2021 Omnibus Incentive Equity Plan (the "2021 Equity Plan"), which was approved by our shareholders at the Annual General Meeting of Shareholders on May 13, 2021. The 2021 Equity Plan is effective for ten years from the date of approval. The aggregate number of common shares that can be issued with respect to equity awards under the 2021 Equity Plan cannot exceed 880,000 shares; plus the number of shares reserved for the 2012 Plan that is in excess of the number of shares related to outstanding grants; plus the number of shares subject to existing grants under the 2012 Plan that may expire or be forfeited or cancelled.

On July 12, 2012, the Board of Directors adopted the Masonite International Corporation 2012 Equity Incentive Plan, which was amended on June 21, 2013, by our Board of Directors, further amended and restated by our Board of

Directors on February 23, 2015, and approved by our shareholders on May 12, 2015 (as amended and restated, the "2012 Plan").

The 2021 Equity Plan and the 2012 Plan ("the Plans") were adopted because the Board of Directors believes that long-term incentive awards granted under the Plans will help to attract, motivate and retain employees and non-employee directors, align employee and stockholder interests and encourage a performance-based culture built on employee stock ownership. The Plans permit us to offer eligible directors, employees and consultants cash and share-based incentives, including stock options, stock appreciation rights, restricted stock, other share-based awards (including restricted stock units) and cash-based awards. The Plans are effective for ten years from the date of its adoption. Awards granted under the Plans are at the discretion of the Human Resources and Compensation Committee of the Board of Directors. The Human Resources and Compensation Committee may grant any award under the Plans in the form of a performance award. The Plans may be amended, suspended or terminated by the Board at any time; provided, that any amendment, suspension or termination which impairs the rights of a participant is subject to such participant's consent and; provided further, that certain material amendments are subject to shareholder approval. As of December 31, 2023, there were 773,165 shares of common stock available for future issuance under the 2021 Equity Plan.

Deferred Compensation Plan

We offer to certain of our employees and directors a Deferred Compensation Plan ("DCP"). The DCP is an unfunded non-qualified deferred compensation plan that permits those certain employees and directors to defer a portion of their compensation to a future time. Eligible employees may elect to defer a portion of their base salary, bonus and/or restricted stock units and eligible directors may defer a portion of their director fees or restricted stock units. All contributions to the DCP on behalf of the participant are fully vested (other than restricted stock unit deferrals which remain subject to the vesting terms of the applicable equity incentive plan) and placed into a grantor trust, commonly referred to as a "rabbi trust." Although we are permitted to make matching contributions under the terms of the DCP, we have not elected to do so. The DCP invests the contributions in diversified securities from a selection of investments and the participants choose their investments and may periodically reallocate the assets in their respective accounts. Participants are entitled to receive the benefits in their accounts upon separation of service or upon a specified date, with benefits payable as a single lump sum or in annual installments. All plan investments are categorized as having Level 1 valuation inputs as established by the FASB’s Fair Value Framework.

Assets of the rabbi trust, other than Company stock, are recorded at fair value and included in other assets in the consolidated balance sheets. These assets in the rabbi trust are classified as trading securities and changes in their fair values are recorded in other (income) expense, net in the consolidated statements of income and comprehensive income. The liability relating to deferred compensation represents our obligation to distribute funds to the participants in the future and is included in other liabilities in the consolidated balance sheets. As of December 31, 2023, the liability and asset relating to deferred compensation had a fair value of $8.4 million and $7.5 million, respectively. As of January 1, 2023, the liability and asset relating to deferred compensation had a fair value of $7.2 million and $7.0 million, respectively. Any gain or loss relating to changes in the fair value of the deferred compensation liability is recognized in selling, general and administration expense in the consolidated statements of income and comprehensive income.

As of December 31, 2023, participation in the DCP is limited and no restricted stock awards have been deferred into the DCP.

Stock Appreciation Rights

We have granted Stock Appreciation Rights ("SARs") to certain employees, which entitle the recipient to the appreciation in value of a number of common shares over the exercise price over a period of time, each as specified in the applicable award agreement. The exercise price of any SAR granted may not be less than the fair market value of our common shares on the date of grant. The compensation expense for the SARs is measured based on the fair value of the SARs at the date of grant and is recognized over the requisite service period. The SARs vest over a maximum of three years, have a life of ten years and settle in common shares. It is assumed that all time-based SARs will vest.

The total fair value of SARs vested was $0.7 million, $0.8 million and $0.8 million, in the years ended December 31, 2023, January 1, 2023, and January 2, 2022, respectively.

The value of SARs granted in the year ended December 31, 2023, as determined using the Black-Scholes-Merton valuation model, was $1.0 million and is expected to be recognized over the average requisite service period of 2.0 years. Expected volatility is based upon the historical volatility of our common shares amongst other considerations. The expected term is calculated based on historical employee behavior and the contractual term of the options amongst other considerations. The weighted average grant date assumptions used for the SARs granted were as follows for the periods indicated:

	2023 Grants			2022 Grants			2021 Grants

Restricted Stock Units

We have granted Restricted Stock Units ("RSUs") to directors and certain employees under the 2021 Equity Plan and the 2012 Plan. The RSUs confer the right to receive shares of our common stock at a specified future date or when certain conditions are met. The compensation expense for the RSUs awarded is based on the fair value of the RSUs at the date of grant, which is equal to the stock price on the date of grant, and is recognized over the requisite service period. The RSUs vest over a maximum of three years and call for the underlying shares to be delivered no later than 30 days following the vesting date unless the participant is subject to a blackout period. In such case, the shares are to be delivered once the blackout restriction has been lifted. It is assumed that all time-based RSUs will vest.

____________

(1) A portion of the vested RSUs delivered were net share settled to cover statutory requirements for income and other employment taxes. We remit the equivalent cash to the appropriate taxing authorities. These net share settlements had the effect of share repurchases by us as we reduced and retired the number of shares that would have otherwise been issued as a result of the vesting.

RSUs granted during the year ended December 31, 2023, vest at specified future dates with only service requirements. The value of RSUs granted in the year ended December 31, 2023, was $19.2 million and is being recognized over the weighted average requisite service period of 2.0 years. During the year ended December 31, 2023, 139,336 RSUs vested at a fair value of $13.0 million.

Performance-based Restricted Stock Units

We have granted certain Performance-based Restricted Stock Units ("PRSUs") under the 2021 Equity Plan and the 2012 Plan. These PRSUs are settled with payouts ranging from zero to 200% of the target award value depending on performance goal achievement. The compensation expense for the PRSUs awarded is based on the fair value of the PRSUs at the date of grant, which is equal to the stock price on the date of grant, and is recognized over the requisite service period. In 2023, we granted certain PRSUs with an additional condition measured by Relative Total Shareholder Return ("TSR"). The compensation expense for these PRSUs is determined using the Monte Carlo simulation method. The PRSUs vest over a maximum of three years and call for the underlying shares to be delivered no later than 30 days following the vesting date unless the participant is subject to a blackout period. In such case, the shares are to be delivered once the blackout restriction has been lifted.

(1) PRSUs are presented as outstanding, granted and forfeited in the table above assuming targets are met and the awards pay out at 100%. Certain awards are settled with payouts ranging from zero to 200% of the target award value depending on achievement. The performance adjustment represents the difference in shares ultimately awarded due to performance attainment above or below target.

(2) A portion of the vested PRSUs delivered were net shares settled to cover statutory requirements for income and other employment taxes. We remit the equivalent cash to the appropriate taxing authorities. These net share settlements had the effect of share repurchases by us as we reduced and retired the number of shares that would have otherwise been issued as a result of the vesting.

PRSUs granted during the year ended December 31, 2023, vest at specified future dates based on both performance and service requirements, while certain PRSUs also vest based on TSR. The value of PRSUs granted in the year ended December 31, 2023, was $9.7 million and is being recognized over the weighted average requisite service period of 3.0 years. During the year ended December 31, 2023, 68,656 PRSUs vested at a fair value of $5.4 million.

Over the past several years, we have engaged in a series of restructuring programs related to exiting certain geographies and non-core businesses, consolidating certain internal support functions and engaging in other actions designed to reduce our cost structure and improve productivity. These initiatives primarily consist of severance actions and plant closure costs. Management continues to evaluate our business; therefore, in future years, there may be additional provisions for new plan initiatives, as well as changes in previously recorded estimates, as payments are made or actions are completed. Asset impairment charges were also incurred in connection with these restructuring actions for certain assets sold, abandoned or made obsolete as a result of these programs.

In December 2023, we began implementing a plan to improve overall business performance that includes the optimization of our manufacturing capacity and reduction of our overhead and selling, general and administration workforce primarily in our Europe reportable segment (collectively, the "2024 Plan"). The optimization of our manufacturing capacity involves specific plants in the Europe segment and costs associated with the closure of these plants and related headcount reductions. Costs associated with the 2024 Plan include severance and closure charges and will continue throughout 2024. As of December 31, 2023, we expect to incur approximately $6 million to $9 million of additional charges related to the 2024 Plan.

In December 2022, we began implementing a plan to improve overall business performance that includes the optimization of our manufacturing capacity and reduction of our overhead and selling, general and administration workforce primarily in our North American Residential reportable segment as well as actions in the Architectural reportable segment and in our head offices (collectively, the "2022 Plan"). The optimization of our manufacturing capacity involves specific plants in the North American Residential segment and costs associated with the closure of these plants and related headcount reductions. Costs associated with the 2022 Plan include severance and closure charges

and will continue throughout 2024. As of December 31, 2023, we expect to incur approximately $3 million to $8 million of additional charges related to the 2022 Plan.     

As previously stated, we have engaged in restructuring programs over the past several years. The 2019, 2020, and 2021 restructuring programs have been aggregated as "Other Plans" for this note. As of December 31, 2023, we do not expect to incur any material future charges related to the Other Plans.

Asset Impairment Charges [Abstract]

Asset Impairment

Asset Impairment

During the year ended December 31, 2023, we recognized asset impairment charges of $33.1 million, net of foreign currency translation, related to a goodwill impairment charge in the Europe reporting unit due to weakening consumer confidence in the United Kingdom that continues to affect demand in the repair and remodel market, negative impacts from rising energy and fuel costs, partly attributable to geopolitical conflicts, as well as rising costs for raw materials and material supply constraints. The quantitative impairment test was conducted using multiple valuation techniques, including a discounted cash flow analysis and market approach, which utilizes Level 3 fair value inputs, and resulted in a goodwill impairment charge. The charge represents the amount by which the carrying value of the Europe reporting unit exceeded its fair value, and was recorded in the consolidated statements of income and comprehensive income and reduced the goodwill balance in the Europe reporting unit from $60.0 million to $26.8 million, excluding foreign exchange fluctuations. See Note 7 for further information.

During the year ended January 2, 2022, we recognized asset impairment charges of $69.9 million, of which $59.5 million related to a goodwill impairment charge in the Architectural reporting unit as a result of manufacturing constraints due to COVID-19 related absenteeism, material availability and production challenges and $10.4 million related to assets in the Architectural segment and an asset in the Corporate & Other category as a result of announced plant closures under the 2021 and 2020 Plans. The quantitative impairment test in the Architectural reporting unit was conducted using multiple valuation techniques, including a discounted cash flow analysis and market approach, which utilizes Level 3 fair value inputs, and resulted in the goodwill impairment charge. The $10.4 million charge represents the amount by which the carrying value of the Architectural reporting unit exceeded its fair value and reduced the goodwill balance from $59.5 million to zero. The asset impairment charge was determined based upon the excess of the carrying values of property, plant and equipment over the respective fair values of such assets, determined using a discounted cash flows approach for each asset group. The fair value of the assets was determined to be $6.3 million, compared to a book value of $16.7 million, with the difference representing the asset impairment charges recorded in the consolidated statements of income and comprehensive income.

Each of these valuations was performed on a non-recurring basis and is categorized as having Level 3 valuation inputs as established by the FASB's Fair Value Framework. The Level 3 unobservable inputs include an estimate of future cash flows and the salvage value for each of the assets.

Management assesses the available positive and negative evidence to estimate if sufficient future taxable income will be generated to use the existing deferred tax assets.

As of December 31, 2023, and January 1, 2023, a valuation allowance of $12.1 million and $14.1 million, respectively, has been established to reduce the deferred tax assets to an amount that is more likely than not to be realized. We have established valuation allowances on certain deferred tax assets resulting from loss carryforwards and other assets in Canada, Costa Rica and the United Kingdom.

The following is a rollforward of the valuation allowance for deferred tax assets:

	Year Ended
(In thousands)	December 31, 2023		January 1, 2023		January 2, 2022

Balance at end of period	$	12,113	$	14,102	$	10,286

The losses carried forward for tax purposes are available to reduce future taxable income by $108.2 million. We can apply these losses against future taxable income based on the period of expiration as follows:

Total tax losses carried forward	$	74,186	$	33,974	$	108,160

We have outside basis differences, including undistributed earnings in our foreign subsidiaries. For those subsidiaries in which we are considered to be indefinitely reinvested, no provision for Canadian income or local country withholding taxes has been recorded. Upon reversal of the outside basis difference and/or repatriation of those earnings, in the form of dividends or otherwise, we may be subject to both Canadian income taxes and withholding taxes payable to the various foreign countries. For those subsidiaries where the earnings are not considered indefinitely reinvested, taxes have been accrued. The determination of the unrecorded deferred tax liability for temporary differences related to investments in foreign subsidiaries that are considered to be indefinitely reinvested is not considered practicable.

As of December 31, 2023, and January 1, 2023, our unrecognized tax benefits were $6.8 million and $7.7 million, respectively, excluding interest and penalties. The unrecognized tax benefits would favorably impact the effective tax rate if the tax benefits were recognized. The unrecognized tax benefits are recorded in other long-term liabilities and as a reduction to related long-term deferred income taxes in the consolidated balance sheets. The changes to our unrecognized tax benefits were as follows:

	Year Ended
(In thousands)	December 31, 2023		January 1, 2023		January 2, 2022
Unrecognized tax benefit at beginning of period	$	7,680	$	7,592	$	8,108

Lapse of statute of limitations	(523)		—		(511)
Unrecognized tax benefit at end of period	$	6,831	$	7,680	$	7,592

We recognize interest and penalties accrued related to unrecognized tax benefits as income tax expense. During the years ended December 31, 2023, January 1, 2023, and January 2, 2022, we recorded accrued interest of $0.7 million, $0.6 million and $0.4 million, respectively. Additionally, we have recognized a liability for accumulated penalties of $0.2 million, $0.3 million and $0.3 million, and accumulated interest of $3.2 million, $3.1 million and $2.8 million, respectively. The interest and penalties accrued related to unrecognized tax benefits would also favorably impact the effective tax rate if those benefits were recognized.

We estimate that the amount of unrecognized tax benefits will decrease within the 12 months following the reporting date by approximately $4.5 million due to lapse of statute of limitations.

We are subject to taxation in Canada, the United States and other foreign jurisdictions. As of December 31, 2023, we are no longer subject to Canadian income tax examination for years prior to 2019. Additionally, we are no longer subject to U.S. federal tax examinations for years prior to 2020. To the extent that income tax attributes such as net operating losses and tax credits have been carried forward from years prior to 2020, those attributes can still be audited when utilized on returns subject to audit. In state and local jurisdictions, we are no longer subject to income tax examination for years prior to 2017.

On August 16, 2022, President Biden signed the Inflation Reduction Act of 2022 ("IRA") into law. The IRA includes several changes to existing tax law, including a minimum tax on adjusted financial statement income of applicable corporations and an excise tax on certain corporate stock buybacks. The tax provisions included in the IRA

are generally effective beginning January 1, 2023, and there was no significant impact to the consolidated financial statements a

Earnings Per Share [Abstract]

Earnings Per Share

Earnings Per Share

Basic earnings per share ("EPS") is calculated by dividing earnings attributable to Masonite by the weighted average number of our common shares outstanding during the period. Diluted EPS is calculated by dividing earnings attributable to Masonite by the weighted average number of common shares plus the incremental number of shares issuable from non-vested and vested RSUs and SARs outstanding during the period.

	Year Ended
(In thousands, except share and per share information)	December 31, 2023		January 1, 2023		January 2, 2022
Net income attributable to Masonite	$	118,227	$	214,233	$	94,501

Shares used in computing diluted earnings per share	22,345,480		22,772,465		24,562,533
Basic earnings per common share attributable to Masonite	$	5.37	$	9.51	$	3.91
Diluted earnings per common share attributable to Masonite	$	5.29	$	9.41	$	3.85
Anti-dilutive instruments excluded from diluted earnings per common share	97,805		223,968		28,707

The weighted average number of shares outstanding utilized for the diluted EPS calculation contemplates the exercise of all currently outstanding SARs and the conversion of all RSUs. The dilutive effect of such equity awards is calculated based on the weighted average share price for each fiscal period using the treasury stock method.

The Company's Board of Directors approved five share repurchase authorizations, the most recent being an incremental $200.0 million share repurchase program approved on February 21, 2022. In addition, the Company announced that its Board of Directors authorized it to enter into an accelerated share repurchase ("ASR") transaction as part of the new share repurchase program. The Company entered into an ASR transaction during the first quarter of 2022 with a third-party financial institution for the repurchase of $100.0 million of its outstanding common shares. At inception, pursuant to the agreement, the Company paid $100.0 million to the financial institution using cash on hand and received an initial delivery of 848,087 common shares on the same day. The final delivery of 319,678 common shares occurred in the second quarter. The $100.0 million ASR transaction was therefore completed in the second quarter with a total delivery of 1,167,765 common shares at a volume-weighted average price ("VWAP") per share minus an agreed upon discount totaling 85.63 per share. The cash paid was reflected as a reduction of equity at the initial delivery of shares and the number of shares outstanding were reduced at the dates of physical delivery.

The Arrangement Agreement (as defined herein) with Owens Corning restricts our ability to repurchase our shares and therefore our share repurchase program is currently suspended through February 8, 2025, other than for the repurchase of shares associated with tax withholding requirements for share-based compensation.

Segment Reporting [Abstract]

Segment Information

Segment Information

    Our management reviews net sales and Adjusted EBITDA (as defined below) to evaluate segment performance and allocate resources. Net assets are not allocated to the reportable segments. Adjusted EBITDA is a non-GAAP financial measure which does not have a standardized meaning under GAAP and is unlikely to be comparable to similar measures used by other companies. Adjusted EBITDA should not be considered as an alternative to either net income or

operating cash flows determined in accordance with GAAP. Adjusted EBITDA is defined as net income (loss) attributable to Masonite adjusted to exclude the following items:

•    depreciation;

•    amortization;

•    share based compensation expense;

•    loss (gain) on disposal of property, plant and equipment;

•    registration and listing fees;

•    restructuring costs (benefit);

•    asset impairment;

•    loss (gain) on disposal of subsidiaries;

•    interest expense (income), net;

•    loss on extinguishment of debt;

•    other expense (income), net;

•    income tax expense (benefit);

•    other items;

•    loss (income) from discontinued operations, net of tax; and

•    net income (loss) attributable to non-controlling interest.

The definition of Adjusted EBITDA differs from the definitions of EBITDA contained in the indenture governing the 2030 Notes and the 2028 Notes and the credit agreements governing the Term Loan Facility and the ABL Facility. Although Adjusted EBITDA is not a measure of financial condition or performance determined in accordance with GAAP, it is used to evaluate and compare the operating performance of the segments and it is one of the primary measures used to determine employee incentive compensation.

Certain information with respect to reportable segments is as follows for the periods indicated:

Employee Future Benefits

United States Defined Benefit Pension Plan

We had a defined benefit pension plan covering certain active and former employees in the United States ("U.S. Pension Plan"). Benefits under the plan were frozen at various times in the past. On December 9, 2020, the Board of Directors approved a resolution to terminate the U.S. Pension Plan and we initiated the process to terminate and annuitize the plan, which continued into 2021. During the fourth quarter of 2021, we completed balance sheet risk mitigation actions related to the U.S. Pension Plan and terminated the plan. In connection with the plan termination, we settled all future obligations under the U.S. Pension Plan through a combination of lump-sum payments to eligible participants who elected to receive them, and the transfer of any remaining benefit obligations to a third-party insurance company under a group annuity contract, which resulted in the settlement of liabilities to affected participants. As a result of these actions, we recognized a pre-tax pension settlement charge of $23.3 million in the fourth quarter of 2021, primarily comprised of the recognition of past actuarial losses. This charge is recorded within other (income) expense, net in the consolidated statements of income and comprehensive income. Information about the U.S. Pension Plan is as follows for the periods indicated:

The weighted average actuarial assumptions adopted in measuring our U.S. accrued benefit obligations and costs prior to termination were as follows for the periods indicated:

Net periodic pension cost	—	%	—	%	2.4	%
Expected long-term rate of return on plan assets	—	%	—	%	3.5	%

The rate of compensation increase for the accrued benefit obligation and net periodic pension costs for the U.S. Pension Plan is not applicable, as benefits under the plan are not affected by compensation increases.

The expected long-term rate of return on plan assets assumption was derived by taking into consideration the target plan asset allocation, historical rates of return on those assets, projected future asset class returns and net outperformance of the market by active investment managers. An asset return model was used to develop an expected range of returns on the plan investments over a 30-year period, with the expected rate of return selected from a best estimate range within the total range of projected results.

United Kingdom Defined Benefit Pension Plan

We have a defined benefit pension plan in the United Kingdom ("U.K. Pension Plan"), which has been curtailed in prior years. The measurement date used for the accounting valuation of the U.K. Pension Plan was December 31, 2023. Information about the U.K. Pension Plan is as follows for the periods indicated:

	Year Ended

Net plan assets (accrued benefit obligation), end of year	$	323	$	(1,989)

There were $0.4 million of actuarial gains during fiscal year 2023 primarily as a result of asset returns exceeding expectations over the year and future inflation being lower than previously anticipated. In addition, demographic assumptions were updated to imply lower life expectancy and lead to lower liabilities. This change was partially offset by the discount rate decreasing from 4.81% to 4.48%. There were $9.2 million of actuarial gains during fiscal year 2022 primarily as a result of a change in the discount rate from 1.83% to 4.81%. There were no material changes to any other key assumptions nor was there a significant demographic gain or loss.

The net plan assets are recorded within other assets in the consolidated balance sheets. Pension fund assets are invested primarily in equity and debt securities. Asset allocation between equity and debt securities and cash is adjusted based on the expected life of the plan and the expected retirement age of the plan participants. Information with respect to the amounts and types of securities that are held in the U.K. Pension Plan is set forth as follows for the periods indicated:

	Year Ended
	December 31, 2023				January 1, 2023
(In thousands)	Amount		% of Total Plan		Amount		% of Total Plan
Equity securities	$	4,511	21.3	%	$	3,740	20.7	%

	$	21,199	100.0	%	$	18,082	100.0	%

Under the plan's investment policy and strategy, plan assets are invested to achieve a fully funded status based on actuarial calculations, maintain a level of liquidity that is sufficient to pay benefit and expense obligations when due, maintain flexibility in determining the future level of contributions and maximize returns within the limits of risk. The target asset allocation for plan assets in the U.K. Pension Plan for 2023 is 80% other securities and 20% equity securities. Other securities represent investments that are primarily invested in a mixture of debt and equity securities.

The weighted average actuarial assumptions adopted in measuring our U.K. accrued benefit obligations and costs were as follows for the periods indicated:

	Year Ended
	December 31, 2023		January 1, 2023		January 2, 2022
Discount rate applied for:
Accrued benefit obligation	4.5	%	4.8	%	1.8	%
Net periodic pension cost	4.8	%	1.7	%	1.0	%
Expected long-term rate of return on plan assets	4.3	%	3.0	%	4.1	%

The rate of compensation increase for the accrued benefit obligation and net pension cost for the U.K. Pension Plan is not applicable, as the plan was curtailed in prior years and benefits under the plan are not affected by compensation increases.

The expected long-term rate of return on plan assets assumption is derived by taking into consideration the target plan asset allocation, historical rates of return on those assets, projected future asset class returns and net outperformance of the market by active investment managers. An asset return model is used to develop an expected range of returns on the plan investments over a 10-year period, with the expected rate of return selected from a best estimate range within the total range of projected results.

As of December 31, 2023, the estimated future benefit payments from the U.K. Pension Plan for the following future periods are set forth as follows:

(In thousands)	Expected Future Benefit Payments
Fiscal year:
2024	$	1,054
2025	1,198
2026	1,174
2027	1,226
2028	1,301
Thereafter	7,152
Total estimated future benefit payments	$	13,105

Expected contributions to the U.K. Pension Plan during 2024 are $2.2 million.

Overall Pension Obligation

For all periods presented, the U.S. and U.K. Pension Plans were invested in equity securities, equity funds, bonds, bond funds and cash and cash equivalents. All investments are publicly traded and possess a high level of marketability or liquidity. All plan investments are categorized as having Level 1 valuation inputs as established by the FASB’s Fair Value Framework.

The change in the net difference between the pension plan assets and projected benefit obligation that is not attributed to our recognition of pension expense or funding of the plan is recognized in other comprehensive (loss) income within the consolidated statements of income and comprehensive income and the balance of such changes is included in AOCL in the consolidated balance sheets.

Defined Contribution Benefit Plans

We have defined contribution benefit plans covering certain U.S. and foreign subsidiary employees subject to eligibility requirements set up in accordance with local statutory requirements. Contributions made to these plans were $16.5 million, $16.1 million and $15.6 million for the years ended December 31, 2023, January 1, 2023, and January 2, 2022, respectively.

Cumulative translation adjustments are reclassified out of accumulated other comprehensive loss into loss on disposal of subsidiaries in the year ended January 1, 2023, in the consolidated statements of income and comprehensive income. Actuarial net losses are reclassified out of accumulated other comprehensive loss into cost of goods sold in the consolidated statements of income and comprehensive income. Pension settlement charges are reclassified out of accumulated other comprehensive loss into other (income) expense, net, in the consolidated statements of income and comprehensive income.

Foreign currency translation gains as a result of translating our foreign assets and liabilities into U.S. dollars during the year ended December 31, 2023, were $19.1 million, primarily driven by strengthening of the Pound Sterling, the Canadian Dollar, the Mexican Peso, and the Euro in comparison to the U.S. dollar during the period.

Variable Interest Entity

Variable Interest Entity

As of December 31, 2023, and January 1, 2023, we held an interest in one variable interest entity ("VIE"), Magna Foremost Sdn Bhd, which is located in Bintulu, Malaysia. The VIE is integrated into our supply chain and manufactures door facings. We are the primary beneficiary of the VIE based on the terms of the existing supply agreement with the VIE. As primary beneficiary via the supply agreement, we receive a disproportionate amount of earnings on sales to third parties in relation to our voting interest, and as a result, receive a majority of the VIE’s residual returns. Sales to third parties did not have a material impact on our consolidated financial statements. We also have the power to direct activities of the VIE that most significantly impact the entity’s economic performance. As its primary beneficiary, we have consolidated the results of the VIE. Our net cumulative investment in the VIE was comprised of the following as of the dates indicated:

(In thousands)	December 31, 2023		January 1, 2023

Current assets include $3.0 million and $1.0 million of cash and cash equivalents as of December 31, 2023, and January 1, 2023, respectively. Assets recognized as a result of consolidating this VIE do not represent additional assets that could be used to satisfy claims against our general assets. Furthermore, liabilities recognized as a result of consolidating these entities do not represent additional claims on our general assets; rather, they represent claims against the specific assets of the consolidated VIE.

Fair Value of Financial Instruments

Fair Value of Financial Instruments

The carrying amounts of our cash and cash equivalents, restricted cash, accounts receivable, income taxes receivable, accounts payable, accrued expenses and income taxes payable approximate fair value because of the short-term maturity of those instruments. The carrying amount of our Term Loan Facility approximates fair value as the interest rates are variable and reflective of market rates. The estimated fair values and carrying values of our long-term debt instruments were as follows for the periods indicated:

	December 31, 2023				January 1, 2023

5.375% senior unsecured notes due 2028	$	482,285	$	496,609	$	462,495	$	495,868

These estimates are based on market quotes and calculations based on current market rates available to us and are categorized as having Level 2 valuation inputs as established by the FASB’s Fair Value Framework. Market quotes used in these calculations are based on bid prices for our debt instruments and are obtained from and corroborated with multiple independent sources. The market quotes obtained from independent sources are within the range of management’s expectations.

Arrangement Agreement with Owens Corning

On February 8, 2024, we entered into an Arrangement Agreement (the “Arrangement Agreement”) with Owens Corning (“Owens Corning”), a Delaware corporation, and MT Acquisition Co LLC (“Purchaser”), a British Columbia unlimited liability company and a wholly owned subsidiary of Owens Corning. Subject to the terms and conditions of the Arrangement Agreement, Owens Corning, through Purchaser, agreed to acquire the Company for $133.00 per issued and outstanding share of our common stock, no par value (the “Shares”), in an all-cash transaction. Pursuant to the Arrangement Agreement, following consummation of implementation of a court-approved plan of arrangement under the Business Corporations Act (British Columbia) (the “Acquisition”), the Company will be a wholly owned subsidiary of Owens Corning.

Pursuant to the terms of the Arrangement Agreement, and subject to the terms and conditions set forth therein, at the effective time of the Acquisition (the “Effective Time”), each Share (other than any Share that is held by Owens Corning or any of its subsidiaries or any Share as to which dissent rights have been properly exercised by the holder

thereof in accordance with British Columbia law) issued and outstanding immediately prior to the Effective Time will be cancelled and automatically converted into the right to receive $133.00 in cash, without interest.

If the Arrangement Agreement is terminated under certain specified circumstances, we or Owens Corning will be required to pay a termination fee. We will be required to pay Owens Corning a termination fee of $75.0 million under specified circumstances, including (a) termination of the Arrangement Agreement in connection with our entry into an agreement with respect to a Superior Proposal (as defined in the Arrangement Agreement) prior to us receiving stockholder approval of the Acquisition, (b) termination by Owens Corning upon an Adverse Recommendation Change (as defined in the Arrangement Agreement), or (c) termination in certain circumstances by either Owens Corning or us upon failure to obtain Masonite Shareholder Approval (as defined in the Arrangement Agreement) or by Owens Corning if we breach our representations, warranties or covenants in a manner that would result in a failure of an applicable closing condition to be satisfied and, if curable, we fail to cure such breach during specific time periods, in each case, if certain other conditions are met. Owens Corning will be required to pay us a reverse termination fee under specified circumstances, including termination of the Arrangement Agreement due to a permanent injunction arising from Competition Laws (as defined in the Arrangement Agreement) when we are not then in material breach of any provision of the Arrangement Agreement and if certain other conditions are met, in an amount equal to $150.0 million.

The consummation of the Acquisition is subject to customary closing conditions, including, among others, (1) the adoption of a resolution approving the Acquisition by at least two-thirds of the votes cast on such resolution by our stockholders entitled to vote thereon and represented in person or by proxy at the applicable special meeting of our stockholders, (2) the issuance of interim and final orders by the Supreme Court of British Columbia approving the Acquisition, (3) the expiration or termination of any applicable waiting period or periods under the Hart-Scott-Rodino Antitrust Improvements Act of 1976 (as amended) and the receipt of certain required regulatory clearances and approvals in other jurisdictions under applicable antitrust and foreign direct investment laws and regulations, including in Canada, Mexico and the United Kingdom, and (4) absence of any law, injunction, order or other judgment prohibiting, rendering illegal or permanently enjoining the consummation of the Acquisition. Each party’s obligation to consummate the Acquisition is also subject to the accuracy of the other party’s representations and warranties contained in the Agreement (subject, with specified exceptions, to materiality or “Material Adverse Effect” standards), the other party’s performance of its covenants and agreements in the Agreement in all material respects, and in the case of Purchaser’s obligation to consummate the Acquisition, the absence of any “Material Adverse Effect” relating to us.

PGTI

On December 17, 2023, the Company entered into an Agreement and Plan of Merger (the “Merger Agreement”) with PGT Innovations, Inc., (“PGTI”) in which Masonite would have acquired PGTI for a combination of cash and Masonite shares with a total transaction value of $3.0 billion.

Accounting Policies [Abstract]

Basis of Presentation

Basis of Presentation

We prepare these consolidated financial statements in accordance with accounting principles generally accepted in the United States of America ("GAAP"). These consolidated financial statements include the accounts of Masonite International Corporation, a company incorporated under the laws of British Columbia, and its subsidiaries, as of December 31, 2023, and January 1, 2023, and for the years ended December 31, 2023, January 1, 2023, and January 2, 2022.

Our fiscal year is the 52- or 53-week period ending on the Sunday closest to December 31. In a 52-week year, each fiscal quarter consists of 13 weeks. For ease of disclosure, the 13-week periods are referred to as three-month periods and the 52- or 53-week periods are referred to as years. Our 2020 fiscal year, which ended on January 3, 2021, contained 53 weeks of operating results, with the additional week occurring in the fourth quarter.

Changes in Accounting Standards and Policies

Adoption of Recent Accounting Pronouncements

In December 2021, the Financial Accounting Standards Board ("FASB") issued ASU 2021-10, "Government Assistance," which requires annual disclosures that increase the transparency of transactions involving government grants, including (1) the types of transactions, (2) the accounting for those transactions and (3) the effect of those transactions on an entity's financial statements. The guidance was effective for annual periods beginning after December 15, 2021, with early adoption permitted. We have adopted the new guidance as of January 3, 2022, the beginning of fiscal year 2022, and the adoption did not have a material impact on our financial statements or disclosures.

In October 2021, the FASB issued ASU 2021-08, "Accounting for Contract Assets and Contract Liabilities from Contracts with Customers," which clarifies that an acquirer of a business should recognize and measure contract assets and contract liabilities in a business combination in accordance with ASU 2014-09," Revenue from Contracts with Customers" as if the entity had originated the contracts. The guidance was effective for fiscal years beginning after December 15, 2022, with early application permitted. We have adopted the new guidance as of January 2, 2023, the beginning of fiscal year 2023, and the adoption did not have a material impact on our financial statements or disclosures.

Other Recent Accounting Pronouncements not yet Adopted

In December 2023, the FASB issued ASU 2023-09, "Income Taxes (Topic 740) - Improvements to Income Tax Disclosures," which requires public business entities to annually disclose specific categories in the rate reconciliation and provide additional information for reconciling items that meet a quantitative threshold. The guidance is effective for fiscal years beginning after December 15, 2024, with early application permitted. We did not early adopt and believe the adoption of this new guidance will not have a material impact on our financial statements.

In November 2023, the FASB issued ASU 2023-07, "Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures," which improves reportable segment disclosure requirements, primarily through enhanced disclosures about significant segment expenses. The guidance is effective for fiscal years beginning after December 15, 2023, with early application permitted. We did not early adopt and believe the adoption of this new guidance will not have a material impact on our financial statements.

Principles of consolidation

Principles of consolidation:

These consolidated financial statements include the accounts of Masonite and our subsidiaries and the accounts of any variable interest entities for which we are the primary beneficiary. Intercompany accounts and transactions have been eliminated upon consolidation. The results of subsidiaries acquired during the periods presented are consolidated from their respective dates of acquisition using the acquisition method. Subsidiaries are prospectively deconsolidated as of the date we no longer have effective control of the entity.

Translation of consolidated financial statements into U.S. dollars

Translation of consolidated financial statements into U.S. dollars:

These consolidated financial statements are expressed in U.S. dollars. The accounts of the majority of our self-sustaining foreign operations are maintained in functional currencies other than the U.S. dollar. Assets and liabilities for these subsidiaries have been translated into U.S. dollars at the exchange rates prevailing at the end of the period and results of operations at the average exchange rates for the period. Unrealized exchange gains and losses arising from the translation of the financial statements of our non-U.S. functional currency operations are accumulated in the cumulative translation adjustments account in accumulated other comprehensive loss. For our foreign subsidiaries where the U.S. dollar is the functional currency, all foreign currency-denominated accounts are remeasured into U.S. dollars. Unrealized exchange gains and losses arising from remeasurements of foreign currency-denominated assets and liabilities are included within other (income) expense, net in the consolidated statements of income and comprehensive income. Gains and losses arising from international intercompany transactions that are of a long-term investment nature are reported in the same manner as translation gains and losses. Realized exchange gains and losses are included in net income for the periods presented.

Cash and cash equivalents

Cash and cash equivalents:

Cash includes cash equivalents which are short-term highly liquid investments with original maturities of three months or less.

Restricted cash

Restricted cash:Restricted cash includes cash we have placed as collateral for standby letters of credit. The letters of credit guarantee payment to third parties in the event the company is in breach of contract terms as detailed in each letter of credit.

Accounts receivable

Accounts receivable:

Our customers are primarily retailers, distributors and contractors. We record an allowance for credit losses at the time that accounts receivable are initially recorded based on the historical write-off experience and the current economic environment as well as our expectations of future economic conditions. We reassess the allowance at each reporting date. When it becomes apparent, based on age or customer circumstances, that such amounts will not be collected, they are charged to the allowance. Payments subsequently received are credited to the credit loss expense account included within selling, general and administration expenses in the consolidated statements of income and comprehensive income. Generally, we do not require collateral for our accounts receivable.

Inventories

Inventories:

Raw materials, work in process and finished goods are valued at the lower of cost or net realizable value. Cost is determined on a first in, first out basis. In determining the net realizable value, we consider factors such as yield, turnover, expected future demand and past experience.

The cost of inventories includes all costs of purchase, costs of conversion and other costs incurred in bringing the inventories to their present location and condition. The costs of conversion of inventories include costs directly related to the units of production, such as direct labor. They also include a systematic allocation of fixed and variable production overheads that are incurred in converting raw materials into finished goods. Fixed production overheads are those indirect costs of production that remain relatively constant regardless of the volume of production, such as depreciation and maintenance of factory buildings and equipment, and the cost of factory management and administration. Variable production overheads are those indirect costs of production that vary directly, or nearly directly, with the volume of production, such as indirect materials and indirect labor.

To determine the cost of inventory, we allocate fixed expenses to the cost of production based on the normal capacity, which refers to a range of production levels and is considered the production expected to be achieved over a number of periods or seasons under normal circumstances, taking into account the loss of capacity resulting from planned maintenance. Fixed overhead costs allocated to each unit of production are not increased due to abnormally low production. Those excess costs are recognized as a current period expense. When a production facility is completely shut down temporarily, it is considered idle, and all related expenses are charged to cost of goods sold.

Property, plant and equipment

Property, plant and equipment:

Property, plant and equipment are stated at cost. Depreciation is recorded based on the carrying values of buildings, machinery and equipment using the straight-line method over the estimated useful lives set forth as follows:

	Useful Life (Years)
Buildings	20 - 40
Machinery and equipment
Tooling	10 - 25
Machinery and equipment	5 - 25
Molds and dies	20 - 25
Office equipment, fixtures and fittings	3 - 10
Information technology systems	5 - 15

Improvements and major maintenance that extend the life of an asset are capitalized; other repairs and maintenance are expensed as incurred. When assets are retired or otherwise disposed, their carrying values and accumulated depreciation are removed from the accounts.

Property, plant and equipment are tested for impairment when events or changes in circumstances indicate that the carrying value of an asset or asset group may not be recoverable. An impairment loss is recognized when the carrying amount of an asset or asset group being tested for recoverability exceeds the sum of the undiscounted cash flows expected from its use and disposal. Impairments are measured as the amount by which the carrying amount of the asset or asset group exceeds its fair value, as determined using a discounted cash flows approach when quoted market prices are not available.

Leases

Leases:

We determine if a contract is a lease at inception or upon acquisition and reevaluate each time a lease contract is amended or otherwise modified. A lease will be classified as an operating lease if it does not meet any of the criteria for a finance lease. Those criteria include the transfer of ownership of the underlying asset by the end of the lease term; an option to purchase the underlying asset that we would be reasonably certain to exercise; the lease term is for the major part of the remaining economic life of the underlying asset; the present value of the sum of the lease payments and any

residual value guaranteed by us that is not already reflected in the lease payments equals or exceeds substantially all of the fair value of the underlying asset or if the underlying asset is of such a specialized nature that it is expected to have no alternative use to the lessor at the end of the lease term.

The assets and liabilities relating to operating leases are included in operating lease right-of-use assets, accrued expenses, and long-term operating lease liabilities in our consolidated balance sheets. The assets and liabilities relating to finance leases are included in property, plant and equipment, net, accrued expenses and other liabilities in our consolidated balance sheets.

ROU assets represent our right to use an underlying asset for the lease term and lease liabilities represent our obligation to make lease payments arising from the lease. Operating lease ROU assets and liabilities are recognized at the respective lease commencement date based on the present value of lease payments over the expected lease term. Since our leases do not specify implicit discount rates, we use our incremental borrowing rate based on the information available at the commencement date in determining the present value of lease payments. The operating lease ROU asset also includes any initial direct costs and is adjusted for lease incentives and prepaid or accrued rent. The lease term begins on the date when the lessor makes the underlying asset available for use to us, and our expected lease terms include options to extend the lease when it is reasonably certain that we will exercise those options. Lease payments are recognized in the consolidated statements of income and comprehensive income on a straight-line basis over the expected lease term.

Leases with an initial term of 12 months or less are not recorded on the balance sheet, with the related lease expense recognized on a straight-line basis over the lease term. Lease and non-lease components of a contract are combined into a single lease component for accounting purposes.

Our operating leases include leases for real estate (including manufacturing sites, warehouses and offices) and machinery and equipment and our finance leases include leases for real estate. We have no material subleases. Certain of our operating leases contain provisions for renewal ranging from one to four options of one to ten years each.

Goodwill

Goodwill:

We use the acquisition method of accounting for all business combinations, and we evaluate all business combinations for intangible assets that should be recognized apart from goodwill. Goodwill adjustments are recorded for the effect on goodwill of changes to net assets acquired during the measurement period (up to one year from the date of acquisition) for 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.

Goodwill is not amortized, but instead is tested annually for impairment on the last day of fiscal November, or more frequently if events or changes in circumstances indicate the carrying amount may not be recoverable. The test for impairment is performed at the reporting unit level by comparing the reporting unit’s carrying amount to its fair value. Possible impairment in goodwill is first analyzed using qualitative factors such as macroeconomic and market conditions, changing costs and actual and projected performance, amongst others, to determine whether it is more likely than not that the book value of the reporting unit exceeds its fair value. If it is determined more likely than not that the book value exceeds fair value, a quantitative analysis is performed to test for impairment. When quantitative steps are determined necessary, the fair values of the reporting units are estimated through the use of discounted cash flow analysis and market multiples. If the carrying amount exceeds fair value, then goodwill is impaired. Any impairment in goodwill is measured as the excess of the carrying value of goodwill over the fair value.

When developing our discounted cash flow analyses, a number of assumptions and estimates are involved to forecast operating cash flows, including future net sales growth, EBITDA margin, benefits from restructuring initiatives, income tax rates, capital spending, business initiatives and working capital changes. These assumptions may vary significantly among the reporting units. Operating cash flow forecasts are based on operating plans for the early years and historical relationships and long-term economic outlooks for our industry in later years. The discount rate is estimated for each specific reporting unit. Due to the many variables inherent in the estimation of a reporting unit’s fair value and the relative size of our recorded goodwill, differences in assumptions may have a material effect on the results of our impairment analyses. In the year ended December 31, 2023, we recorded $33.1 million in goodwill impairment charges in our Europe reporting unit. There were no impairment charges recorded against goodwill in 2022. In 2021, we

recorded $59.5 million in impairment charges related to the Architectural reporting unit. See Note 14 for further information.

Intangible assets

Intangible assets:

Intangible assets with definite lives include customer relationships, patents, system software development and acquired trademarks and tradenames. Definite lived intangible assets are amortized over their estimated useful lives. Information pertaining to the estimated useful lives of intangible assets is as follows:

	Estimated Useful Life (Years)	Estimated Useful Life
Customer relationships	10 - 15	Over expected relationship period
Patents	10 - 12	Over expected useful life
System software development	5 - 15	Over expected useful life
Acquired trademarks and tradenames	2 - 10	Over expected useful life

Amortizable intangible assets are tested for impairment whenever events or changes in circumstances indicate that the carrying value may be greater than fair value. An impairment loss is recognized when the estimate of undiscounted future cash flows generated by such assets is less than the carrying amount. Measurement of the impairment loss is based on the fair value of the asset. Fair value is measured using discounted cash flows.

Indefinite lived intangible assets are not amortized, but instead are tested for impairment annually on the last day of fiscal November, or more frequently if events or circumstances indicate the carrying value may exceed the fair value.

Income taxes

Income taxes:

As a multinational corporation, we are subject to taxation in many jurisdictions and the calculation of our tax liabilities involves dealing with inherent uncertainties in the application of complex tax laws and regulations in various taxing jurisdictions. We assess the income tax positions and record tax liabilities for all years subject to examination based upon our evaluation of the facts, circumstances and information available as of the reporting date. Our global structure required an assessment of the Company’s interpretation and application of tax laws in multiple jurisdictions including the income tax impact of the legal entity ownership structure and intercompany transactions.

We use the asset and liability method of accounting for income taxes. Under the asset and liability method, deferred tax assets and liabilities are recognized for the deferred tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities due to a change in tax rates is recognized in income in the period that includes the date of enactment. A valuation allowance is recorded to reduce deferred tax assets to an amount that is anticipated to be realized on a more likely than not basis.

We account for uncertain taxes in accordance with ASC 740, "Income Taxes." The initial benefit recognition model follows a two-step approach. First, we evaluate if the tax position is more likely than not of being sustained if audited based solely on the technical merits of the position. Second, we measure the appropriate amount of benefit to recognize. This is calculated as the largest amount of tax benefit that has a greater than 50% likelihood of ultimately being realized upon settlement. Subsequently at each reporting date, the largest amount that has a greater than 50% likelihood of ultimately being realized, based on information available at that date, will be measured and recognized.

We recognize interest and penalties related to unrecognized tax benefits within the income tax expense line in the consolidated statements of income and comprehensive income. Accrued interest and penalties are included within the related tax liability line in the consolidated balance sheets.

Employee future benefits

Employee future benefits:

We maintain defined benefit pension plans. Benefits under the plans were frozen or curtailed at various times in the past. Earnings are charged with the cost of benefits earned by employees as services are rendered. The cost reflects management’s best estimates of the pension plans’ expected investment yields, wage and salary escalation, mortality of members, terminations and the ages at which members will retire. Changes in these assumptions could impact future pension expense. Service cost components are recognized within cost of goods sold and non-service cost components are recognized within other (income) expense, net in the consolidated statements of income and comprehensive income. The excess of the net actuarial gain (loss) over 10% of the greater of the benefit obligation or fair value of plan assets at the beginning of the year is amortized over the average remaining service lives of the members.

Assets are valued at fair value for the purpose of calculating the expected return on plan assets. Past service costs arising from plan amendments are amortized on a straight-line basis over the average remaining service period of employees active at the date of amendment.

When a restructuring of a benefit plan gives rise to both a curtailment and a settlement of obligations, the curtailment is accounted for prior to the settlement. Curtailment gains are offset against unrecognized losses and any excess gains and all curtailment losses are recorded in the period in which the curtailment occurs.

Restructuring costs

Restructuring costs:

Restructuring costs include all salary-related severance benefits that are accrued and expensed when a restructuring plan has been put into place, the plan has received approval from the appropriate level of management and the benefit is probable and reasonably estimable. In addition to salary-related costs, we incur other restructuring costs when facilities are closed or capacity is realigned within the organization. Upon termination of a contract we record liabilities and expenses pursuant to the terms of the relevant agreement. For non-contractual restructuring activities, liabilities and expenses are measured and recorded at fair value in the period in which they are incurred.

Restructuring-related costs are presented separately in the consolidated statements of income and comprehensive income whereas non-restructuring severance benefits are charged to cost of goods sold or selling, general and administration expense depending on the nature of the job responsibilities.

Financial instruments

Financial instruments:

We have applied a framework consistent with ASC 820, "Fair Value Measurement and Disclosure," and have disclosed all financial assets and liabilities measured at fair value and non-financial assets and liabilities measured at fair value on a non-recurring basis (at least annually).

We classify and disclose assets and liabilities carried at fair value in one of the following three categories:

        Level 1: Quoted market prices in active markets for identical assets or liabilities.

        Level 2: Observable market based inputs or unobservable inputs that are corroborated by market data.

        Level 3: Unobservable inputs that are not corroborated by market data.

The estimated fair value of a financial instrument is the amount at which the instrument could be exchanged in a current transaction between willing parties, other than a forced or liquidation sale. These estimates, although based on the relevant market information about the financial instrument, are subjective in nature and, therefore, cannot be determined with precision. Changes in assumptions could significantly affect the estimates.

Share based compensation expense

Share based compensation expense:

We have a share based compensation plan, which is described in detail in Note 12. We apply the fair value method of accounting using comprehensive valuation models, including the Black-Scholes-Merton option pricing model and the Monte Carlo simulation method, to determine the compensation expense.

Revenue recognition and Vendor rebates

Revenue recognition:Revenue from the sale of products is recognized when control of the promised goods is transferred to our customers based on the agreed-upon shipping terms, in an amount that reflects the consideration to which we expect to be entitled in exchange for those goods or services. Volume rebates, expected returns, discounts and other incentives to customers are considered variable consideration and we estimate these amounts based on the expected amount to be provided to customers and reduce the revenues we recognize accordingly. Sales taxes and value added taxes assessed by governmental entities are excluded from the measurement of consideration expected to be received. Shipping and handling costs incurred after a customer has taken possession of our goods are treated as a fulfillment cost and are not considered a separate performance obligation. Shipping and other transportation costs charged to customers are recorded in both revenues and cost of goods sold in the consolidated statements of income and comprehensive income.Vendor rebates:

We account for cash consideration received from a vendor as a reduction of cost of goods sold and inventory, in the consolidated statements of income and comprehensive income and consolidated balance sheets, respectively. The cash consideration received represents agreed-upon vendor rebates that are earned in the normal course of operations.

Product warranties

Product warranties:We warrant certain qualitative attributes of our door products. We have recorded provisions for estimated warranty and related costs within accrued expenses on the consolidated balance sheets, based on historical experience and we periodically adjust these provisions to reflect actual experience.

Advertising costs

Advertising costs:We recognize advertising costs as they are incurred. Advertising costs incurred primarily relate to tradeshows and are included within selling, general and administration expense in the consolidated statements of income and comprehensive income.

Research and development costs

Research and development costs:We recognize research and development costs as they are incurred. Research and development costs incurred primarily relate to the development of new products and the improvement of manufacturing processes, and are primarily included within cost of goods sold in the consolidated statements of income and comprehensive income. These costs exclude the significant investments in other areas such as advanced automation. Research and development costs were $27.8 million, $21.2 million and $18.4 million in the years ended December 31, 2023, January 1, 2023, and January 2, 2022, respectively.

Insurance losses and proceeds

Insurance losses and proceeds:

All involuntary conversions of property, plant and equipment are recorded as losses within loss (gain) on disposal of property, plant and equipment, which is included within selling, general and administration expense in the consolidated statements of income and comprehensive income and as reductions to property, plant and equipment in the consolidated balance sheets. Any subsequent proceeds received for insured losses of property, plant and equipment are also recorded as gains within loss (gain) on disposal of property, plant and equipment, and are classified as cash flows

from investing activities in the consolidated statements of cash flows in the period in which the cash is received. Proceeds received for business interruption recoveries are recorded as a reduction to selling, general and administration expense in the consolidated statements of income and comprehensive income and are classified as cash flows from operating activities in the consolidated statements of cash flows in the period in which an acknowledgment from the insurance carrier of settlement or partial settlement of a non-refundable nature has been presented to us.

Equity investments

Equity investments:

We account for investments in affiliates of between 20% and 50% ownership, over which we have significant influence, using the equity method. We record our share of earnings of the affiliate within other income, net of expense, in the consolidated statements of income and comprehensive income and dividends as a reduction of the investment in the affiliate in the consolidated balance sheets when declared.

Segment reporting

Segment reporting:Our reportable segments are organized and managed principally by end market: North American Residential, Europe and Architectural. The Corporate & Other category includes unallocated corporate costs and the results of immaterial operating segments that were not aggregated into any reportable segment. In addition to similar economic characteristics we also consider the following factors in determining the reportable segments: the nature of business activities, the management structure directly accountable to our chief operating decision maker for operating and administrative activities, availability of discrete financial information and information presented to the Board of Directors and investors.

Use of estimates

Use of estimates:

The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions which affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of the date of the consolidated financial statements and the reported amounts of net sales and expenses during the reporting periods. During 2023, there were no material changes in the methods or policies used to establish estimates and assumptions. Actual results may differ from our estimates.
