Let’s delve into the major driving factors.

Factors Fueling Growth of AWI Stock

Acquisition: Acquisitions continue to be a fundamental driver of Armstrong's growth strategy, helping to expand organically and strengthen its product line. In 2024, the company successfully acquired two architectural solutions companies — Zahner and 3form. Both of them have exceeded expectations by contributing significantly to Architectural Specialties and speeding up market penetration. With the segment seeing double-digit growth and extending AWI's reach into specialty walls, exterior facades and rain screens, the integration of both businesses is proceeding as planned.

Looking ahead, AWI expects to continue with more bolt-on acquisitions for further expansion. It is focused on opportunities that will add to its current offerings and strengthen its position in the construction industry.
 
Digitalization & Technology Efforts: Armstrong is committed to improving technology and implementing digitalization efforts. Kanopi's cost-effective digital initiative has generated new demand for its products, resulting in its contribution to EBITDA growth for the Mineral Fiber segment business. Additionally, the company is committed to maximizing the efficiency of the project design process with its automated design service, Project Works.

Focus on Cost-Control Initiatives: In second-quarter 2025, Armstrong’s net sales rose 16% year over year, while adjusted EPS increased 29%. Adjusted EBITDA grew 23%, and the adjusted EBITDA margin expanded by 200 basis points (bps) to 36%.

Segment-wise, the Mineral Fiber segment witnessed a 350 bps year-over-year EBITDA margin expansion, marking one of the strongest quarterly margin performances since the 2016 separation from the flooring business. For the Architectural Specialties segment, the adjusted EBITDA margin of approximately 22% in the quarter was the highest quarterly margin of any quarter since the third quarter of 2020.

This significant profitability improvement highlights Armstrong’s resilient operating model, disciplined cost control and ability to drive efficiency even in uncertain market conditions.
 
Investment in New Products: Armstrong continues to strengthen its portfolio through product innovation and sustainability-driven initiatives. In the second quarter of 2025, the company expanded its industry scope with the latest innovation for energy-saving ceilings —TEMPLOK. This move improved building efficiency and supported customers’ decarbonization goals. These offerings, combined with ongoing investments in digital tools and design-focused solutions, are driving strong growth across both the Mineral Fiber and Architectural Specialties segments. Management emphasized that innovation remains a core growth driver, reinforcing Armstrong’s competitive advantage and positioning the company for sustained demand.
 
Higher ROE: Armstrong’s trailing 12-month return on equity (ROE) is indicative of its growth potential. The company’s ROE of 39.8% compares favorably with the industry’s 15.2%, which signals more efficiency in using shareholders’ funds than peers.
