Armstrong World Industries is the dominant North American maker of ceiling systems — mineral fiber tiles and architectural specialties — operating 22 plants plus its WAVE grid joint venture. It is a steady, high-return compounder. FY2025 revenue grew 12.1% to $1.62B, operating income rose 15.1% to $431M (a 26.6% operating margin), and net income climbed 16.5% to $309M (a 19.0% net margin), lifting diluted EPS 17.6% to $7.08. This is not a one-year story: revenue has risen every year from $1.11B in FY2021 to $1.62B in FY2025, and net income from $183M to $309M — durable, consistent growth driven by pricing power, mix (the higher-growth Architectural Specialties segment), and operational productivity.
