Business Description

MasterBrand, Inc. (“we,” “us,” “our,” “MasterBrand” or the “Company”), was founded over 70 years ago in 1954 under the name United Cabinet Incorp orated. We are the largest manufacturer of residential cabinets in North America, based on 2024 reported net sales. O ur products are sold throughout the United States and Canada to the remodeling and new construction markets through three primary channels: dealers, retailers and builders. On December 14, 2022, our former parent company, Fortune Brands Innovations, Inc. (formerly known as Fortune Brands Home & Security, Inc.) (“Fortune Brands”), completed a tax free spin-off transaction to separate its Cabinets segment into a standalone publicly-traded company (the “Separation”). The Separation was completed through a series of transactions ending with a pro rata distribution of all of the shares of MasterBrand, Inc. common stock owned by Fortune Brands to Fortune Brands shareholders, after which we became an independent, publicly-traded company. On July 10, 2024, we acquired all of the issued and outstanding limited liability interests of Dura Investment Holdings LLC, the parent company of Supreme Cabinetry Brands, Inc. (“Supreme”), a cabinetry company. Supreme was a domestic manufacturer of residential cabinetry with a portfolio of product lines significantly focused on premium products. Supreme, with manufacturing facilities located in Minnesota, Iowa and North Carolina, and its two brands, Dura Supreme and Bertch cabinetry, crafts framed and frameless cabinetry for a nationwide network of dealers. On August 6, 2025, we announced the execution of a definitive agreement whereby the Company will combine with American Woodmark Corporation (“American Woodmark”), a Virginia corporation, in an all-stock transaction. The Company, Maple Merger Sub, Inc. (“Merger Sub”), a Virginia corporation and direct, wholly owned subsidiary of the Company, and American Woodmark entered into an Agreement and Plan of Merger (the “Merger Agreement”), pursuant to which, and subject to the satisfaction or waiver of the conditions set forth in the Merger Agreement, Merger Sub will merge with and into American Woodmark, with American Woodmark surviving the merger and continuing as a wholly owned subsidiary of the Company (the “Merger”). The closing of the Merger, which is expected to occur in early 2026, is subject to the receipt of clearance under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, and the satisfaction or waiver of other customary closing conditions. Both companies received the necessary shareholder approval at their respective special meetings of shareholders held on October 30, 2025. Strategy Our superior product quality, innovative design and service excellence drives a compelling value proposition. We have insight into the fashion and features consumers desire, which we use to tailor our product lines across price points. Our volume leadership allows us to achieve an advantaged cost structure and service platform by standardizing product platforms and components to the greatest extent possible—resulting in a more flexible facility footprint and an efficient supply chain. Further, our decades of experience have informed how we use global geographies to optimize procurement and manufacturing costs. Finally, with the most extensive dealer network throughout the United States and Canada, we have an advantaged distribution model that we believe cannot be easily replicated. We plan to further extend our competitive advantages by using technology and data to enhance the consumer’s experience from visualization and ordering to delivery and installation. We believe we are only beginning to unlock the potential value of our unique combination of scale, operational agility, data-first operating model and strong continuous improvement culture. We intend to continue to distinguish this advantaged platform by capitalizing on the powerful demographic trends that we expect will drive repair and remodel (“R&R”) and new construction growth for years to come. We believe the combination of our leading market position and size, strategic vision, strong partnerships and commitment to continuous improvement will drive our future growth.…
