In its own words
What could break it.
Commodity & input dependence
- raw materials — fiberglass, perlite, recycled paper, starch, aluminum, steel, natural gasmedium
Armstrong's results are exposed to input-cost swings in its largest raw materials — fiberglass, perlite, recycled paper and starch, plus aluminum, steel and natural gas; higher energy and raw-material costs were a ~$5M operating-income headwind in 2025.
“Our largest raw material expenditures are primarily for fiberglass, perlite, recycled paper, and starch. Other raw materials include clays, felt, pigment, architectural resin and glass, wood and wood fiber. We manufacture substantially all of our mineral wool at one of our manufacturing facilities. We use aluminum and steel in the production of metal building products by us and by WAVE. Finally, natural gas and packaging materials also represent significant input costs. Fluctuations in the prices of these inputs impact our financial results.”
