The following slide highlights the key takeaways from the quarter, emphasizing the double-digit growth in both revenue and earnings:
Detailed Financial Analysis
The Mineral Fiber segment’s strong performance was driven by a combination of solid average unit value (AUV) growth of 5%, primarily from like-for-like pricing and favorable mix, along with modest volume contribution. The segment’s adjusted EBITDA margin expanded an impressive 350 basis points to 45.2%, benefiting from productivity gains, well-controlled SG&A expenses, and strong contribution from WAVE equity earnings.
As illustrated in this detailed breakdown of the Mineral Fiber segment’s performance:
The Architectural Specialties segment delivered even more robust results, with net sales growth of 37% year-over-year. This exceptional performance was driven by both organic growth of 15% and better-than-expected contributions from the 2024 acquisitions of 3form and Zahner. The segment’s adjusted EBITDA margin expanded 310 basis points to 21.5%, with organic adjusted EBITDA margin reaching 22.1%.
The following chart details the drivers behind the Architectural Specialties segment’s strong performance:
On a consolidated basis, Armstrong World Industries’ adjusted EBITDA increased by $29 million compared to Q2 2024, reaching $154 million. This growth was primarily driven by higher volumes (+$25 million), improved AUV (+$8 million), and increased equity earnings (+$5 million), partially offset by higher manufacturing costs, input costs, and SG&A expenses.
The waterfall chart below illustrates the factors contributing to the adjusted EBITDA growth:
For the first half of 2025, Armstrong World Industries has maintained strong execution, with year-to-date net sales up 17% to $807 million and adjusted EBITDA increasing 20% to $283 million.

Strategic Initiatives
Armstrong World Industries continues to effectively deploy its adjusted free cash flow to fund all capital allocation priorities.

The strong performance of recent acquisitions, particularly 3form and Zahner, highlights the success of Armstrong World Industries’ inorganic growth strategy. These acquisitions are performing better than expected and contributing significantly to the Architectural Specialties segment’s growth.
Forward-Looking Statements
Based on the strong first-half performance, Armstrong World Industries has raised its full-year 2025 guidance across all key metrics. The company now expects net sales of $1,600 million to $1,630 million (11-13% year-over-year growth), adjusted EBITDA of $545 million to $560 million (12-15% growth), adjusted diluted EPS of $7.15 to $7.30 (13-16% growth), and adjusted free cash flow of $330 million to $345 million (11-16% growth).
The updated guidance and management commentary are presented in the following slide:
Despite the raised guidance, management still expects a softer second half of the year, with Mineral Fiber volume projected to be flat to down low-single-digits for the full year. However, this is expected to be offset by Mineral Fiber AUV growth exceeding 6% and continued strong performance in the Architectural Specialties segment. The company also anticipates WAVE equity earnings to grow at high-single digits.
The updated segment assumptions include Mineral Fiber net sales growth of approximately 5% with an adjusted EBITDA margin of around 43%, and Architectural Specialties net sales growth exceeding 25% with an adjusted EBITDA margin of approximately 19%.
Armstrong World Industries’ Q2 2025 results demonstrate the company’s ability to execute effectively in a challenging environment, leveraging pricing power, operational efficiency, and strategic acquisitions to deliver strong financial performance. With raised guidance for the full year, the company is well-positioned to continue its growth trajectory through the remainder of 2025.
