Segment performance

SegmentRevenueYoYQoQMargin
Mineral Fiber
Sales grew 3% in Q4, driven by 6% AUV growth (favorable like-for-like pricing and positive mix), partially offset by lower sales volumes due to the federal government shutdown and softer home center demand. Adjusted EBITDA grew 15% in Q4, with adjusted EBITDA margin expanding 460 bps to a record 42.1% for a Q4. Full-year adjusted EBITDA margin reached a record 43.5%.
AUV growth: 6%Adjusted EBITDA growth: 15%
3% growth——42.1%
Architectural Specialties (AS)
Double-digit sales growth of 11% in Q4 was driven by contributions from 2024 acquisitions (3form, Zahner) and organic growth. Full-year organic sales grew 9%. Adjusted EBITDA decreased 3% in Q4, with margins negatively impacted by softer organic top-line performance, less favorable operating leverage due to custom project timing, and higher manufacturing/SG&A costs from acquisitions and capacity investments. Full-year adjusted EBITDA margin was 18%, below the 19% guidance. Order intake continued strong at double-digit levels in Q4, with strength in the transportation vertical.

Risks & headwinds

Market Uncertainty 2026

High levels of uncertainty

Mitigation:Focus on growth initiatives and operational excellence.

Federal Government Shutdown Impact Q4 FY25

Softer Mineral Fiber volumes

Mitigation:Expected bounce back in subsequent months, factored into 2026 outlook.

Architectural Specialties Project Delays Q4 FY25

Temporarily compressed margins in AS segment

Mitigation:Expected to work itself out; company has levers to achieve 20% EBITDA margin goal.

Seasonality and Winter Weather Q1 and H1 FY26

More muted start to 2026, slightly softer Mineral Fiber volumes in H1

Mitigation:Anticipated and factored into guidance; stronger back half expected.

Home Center Demand Softness Q4 FY25

Softer volumes

Mitigation:Primarily due to destocking, a recurring dynamic.

What to watch in Q1 FY26

Current Softer in H1 FY26
Target Growth in H2 FY26

Why it matters

Verifying the expected stronger back half for Mineral Fiber volumes is crucial for overall revenue and profitability targets.

Accordingly, we anticipate Mineral Fiber volume in the first half of the year to be slightly softer than the back half as a result of these dynamics.

Q&A highlights

What is the price and mix split for the 6% AUV growth in 2026, and how sustainable is pricing power given the competitive environment and customer feedback?

AUV growth is above historical levels. In 2025, pricing had a greater bias than mix due to inflationary pressures. For 2026, with anticipated mid-single-digit inflation, the company expects to continue pricing ahead of inflation, resulting in a similar positive bias towards like-for-like pricing and mix. Pricing power is sustained by innovation, service, and quality.

“Going forward, as Chris can outline, we're seeing -- we're anticipating some additional inflation in '26, and our expectation is with our normal cadence on pricing, we're going to continue to price ahead of that inflation and likely to end up with a more positive bias toward like-for-like pricing and mix in the year.”

Detailed narrative

CEO Transition and Strategic Continuity

Vic Grizzle will transition from CEO to Executive Chairman on April 1, 2026, with Mark Hershey, current COO, assuming the role of President and CEO. The company emphasizes strategic continuity under new leadership, maintaining focus on innovation, growth initiatives (digital, energy savings, data centers), productivity, and inorganic growth through M&A and partnerships. The overarching objective remains consistent profitable growth.

Innovation in Energy Efficiency and Data Centers

Armstrong World Industries is prioritizing innovation aligned with macro trends in energy reduction and data center expansion. The company introduced an upgraded TEMPLOK energy-saving ceiling solution, enhancing passive heating/cooling and design flexibility, with early adoption in office renovations and higher education.

For data centers, new DATAZONE panels and DYNAMAX LT Structural Grid Solutions were launched, designed for mission-critical environments requiring higher load capacity and improved airflow management. Additionally, SKYLO, an integrated walkable ceiling system, was introduced for clean rooms and advanced manufacturing.

Architectural Specialties Expansion and Acquisitions

The Architectural Specialties (AS) segment continues to expand its portfolio and capabilities through strategic acquisitions. Following the 2024 acquisitions of 3form and Zahner, and Parallel Architectural Products in Q4 2025, the company recently acquired Eventscape. Eventscape, which generated approximately $30 million in revenue in 2025, is expected to be a positive contributor in 2026, enhancing AWI's ability to design and fabricate with diverse materials and strengthening relationships with architects and designers.

Market Outlook and Office Vertical Dynamics

Management anticipates slightly improving market conditions in 2026, with transportation, data centers, and healthcare/education verticals expected to provide tailwinds. While high levels of uncertainty persist regarding policy, interest rates, and geopolitical events, the office vertical appears to have bottomed. Project bids in the office segment are showing meaningfully higher values, indicating increased investment by building owners in aesthetics, functionality, and amenities to attract and retain tenants.

Growth Initiatives Driving Above-Market Performance

Armstrong's growth initiatives, including digital platforms like PROJECTWORKS and Kanopi, contributed 1 point of growth in 2025. With the acceleration from new opportunities in data centers and energy savings, these initiatives are projected to contribute an additional 0.5 point of growth in 2026, totaling 1.5 points.

These efforts are key building blocks for consistent Mineral Fiber AUV growth and incremental volume growth ahead of the market, reinforcing the company's ability to deliver above-market performance.
