Amrize is a North American building materials and building envelope company, spun off from Holcim in June 2025, serving infrastructure, commercial, and residential construction customers across the U.S. and Canada. The company operates two segments. Building Materials (~55-60% of revenue) produces and sells cement, aggregates, ready-mix concrete, and asphalt — commodity construction inputs sold by volume to a highly diversified customer base. Because freight costs are high relative to product price, this is an inherently local business where plant and quarry proximity to customers is the primary profitability driver. Building Envelope (~40-45% of revenue) sells branded roofing and wall systems under brands including Duro-Last, Elevate, Malarkey, OX Engineered Products, Enverge, and Gaco. Products include single-ply membranes, residential shingles, spray foam insulation, wall sheathing, and liquid-applied coatings. Building Envelope serves both commercial and residential customers, with roughly 70% of sales through distributors and 30% direct to contractors. Commercial R&R — replacing aging roofs — is the most resilient demand category, while residential new construction is the most cyclical. Amrize's growth strategy combines organic capacity expansion (including at Ste. Genevieve, its largest cement plant at 5.5M tons annually), bolt-on M&A in aggregates, and continued platform-building in Building Envelope. The company is also executing ASPIRE, a cost savings program targeting $250M in cumulative savings by 2028.
