Segment Analysis

Mineral Fiber Segment

The Mineral Fiber segment, which represents approximately 63% of total sales, delivered solid results with net sales of $267 million, up 7% compared to Q2 2024. The segment’s adjusted EBITDA margin expanded significantly by 350 basis points to an impressive 45.2%.

This performance was driven by several factors, including:

The Architectural Specialties segment demonstrated exceptional growth with net sales of $158 million, a 37% increase compared to Q2 2024. The segment’s adjusted EBITDA margin expanded by 310 basis points to 21.5%.

This robust performance was driven by:

• 15% organic sales growth
• Better-than-expected contribution from the 2024 acquisitions of 3form and Zahner

Raised Guidance and Outlook

Based on the strong first-half performance, Armstrong has raised its full-year 2025 guidance across all key metrics. The company now expects:

The revised guidance represents significant increases from previous projections:

• Net sales growth raised to 11-13% (from 9-11%)
• Adjusted EBITDA growth increased to 12-15% (from 8-12%)
• Adjusted diluted EPS growth elevated to 13-16% (from 9-13%)
• Adjusted free cash flow growth improved to 11-16% (from 6-12%)

Management commentary indicates that while they expect a softer second half of the year with Mineral Fiber volume flat to down low-single-digits for the full year, strong execution and order intake support the improved outlook, particularly in the Architectural Specialties segment.

Capital Allocation and Cash Flow

Armstrong continues to generate strong cash flow, with year-to-date adjusted free cash flow up 29% compared to the prior year. The company is deploying this cash across multiple priorities, including capital expenditures, dividends, and share repurchases.

As shown in the following chart, share repurchases have more than doubled in 2025 compared to the same period in 2024:

The company’s capital allocation strategy reflects confidence in its long-term growth prospects, with increased investments in both organic growth initiatives and shareholder returns.

Strategic Initiatives

Armstrong’s performance is supported by several strategic initiatives, including product innovations and recent acquisitions. The 2024 acquisitions of 3form and Zahner are performing better than expected, contributing significantly to the Architectural Specialties segment’s growth.

The company continues to focus on margin expansion through pricing strategies, favorable product mix, and operational efficiencies. Despite input cost inflation, Armstrong has successfully expanded margins across both business segments.

Looking ahead, Armstrong remains well-positioned to capitalize on renovation opportunities in its installed base, with energy-saving products and e-commerce platform expansion expected to drive future growth.
