BlueLinx Holdings Inc.2025Annual Report Dear Shareholders, In 2025, we achieved solid results through the successful execution of our growth strategy, andour long-term approach continues to position BlueLinx to capitalize on the durable fundamentalsof the housing and building products sector. We remain focused on profitable sales growth byexecuting on a differentiated product and channel strategy, emphasizing higher margin specialtyproducts, expanding our business with strategic customer and supplier accounts, and offeringdifferently disruptive value-add services. We believe that consistently investing throughout all phases of the economic cycle — not onlyduring periods of market growth or contraction — has helped us achieve strong net sales andsolid gross margins, while strengthening our differentiated value proposition to customers andsuppliers. For 2025, we generated $3.0 billion in net sales, with specialty products once again representingapproximately 70% of net sales and over 80% of gross profit for the year. Specialty products alsodelivered gross margins of 18.0%. Our five key specialty product categories—engineered wood,siding, millwork, industrial, and outdoor living—benefited from effective pricing, strong supplierpartnerships, high customer loyalty, and disciplined inventory management, while structuralproducts continued to complement our specialty products portfolio, rounding out the solutions weoffered to our customers. We are especially pleased with the share gains we experienced withseveral national accounts, within the multi-family channel, and across certain product categories,including engineered wood products and outdoor living products. Our share gain initiativesenabled volume growth, expanded branded and private label product offerings, and led to deepercustomer and supplier relationships, all of which contributed to solid net sales and gross margins. We also advanced our multi-year digital transformation, with enhancements made to our masterdata platform and the implementation of a new transportation management system. We expandedour focus on advanced digital tools, including AI-enabled initiatives, to improve productivity,support commercial execution, and strengthen operational excellence. Our acquisition of Disdero Lumber Company further advanced our strategic priorities byexpanding our specialty product offerings, increasing multifamily exposure, and strengtheningour presence in the Western United States. We are encouraged by its performance and continue tobelieve in the long-term growth potential of the business. Our financial position remains strong, ending the year with total available liquidity of $726million, including $386 million in cash on hand. This financial strength provides flexibility toinvest in the business, pursue disciplined growth opportunities, and navigate ongoing marketuncertainty. We also continued to return capital to shareholders through opportunistic share repurchases totaling $38 million during the year, reflecting our commitment to thoughtful capitalallocation. We believe in the long-term fundamentals of the housing and building products sector, and ourstrategy will continue to be designed to address single and multi-family starts as well as repairand remodel activity.
