ARMSTRONG WORLD INDUSTRIES INC Q4 FY2024 earnings call

• Record-setting fourth quarter and full year 2024 results with net sales up nearly 12%, adjusted EBITDA up 13%, adjusted free cash flow up 13%, and adjusted diluted earnings per share up 19%.
• Both Mineral Fiber and Architectural Specialty segments contributed to record results. Mineral Fiber had 10% EBITDA growth and 70 basis points of margin expansion. Architectural Specialty saw strong sales growth from acquisitions and organic sales acceleration.
• Strategic acquisitions like 3Form, Zaynor, and BOCE expanded the portfolio, creating competitive advantages, especially in interior and exterior architectural metal solutions.
• Innovation in energy-saving Temploc ceiling tiles, which may qualify for investment tax credits and are approved for government use, driving long-term growth.
• Capital allocation priorities include reinvesting in the business, strategic acquisitions, and returning cash to shareholders via dividends and share repurchases.

For the full year, Mineral Fiber ended with approximately 6% net sales growth, 11% adjusted EBITDA growth, and adjusted EBITDA margin expansion of more than 200 basis points. Architectural Specialties generated year-over-year net sales growth of 27% and adjusted EBITDA growth of 24%. On an organic basis, the architectural specialty segment expanded adjusted EBITDA margin by 40 basis points to approximately 19%. In the fourth quarter, Mineral Fiber achieved 9% average unit value (AUV) growth, driven by mix and like-for-like pricing, with full-year AUV growth of 7%. Architectural Specialty sales increased 41% in the quarter, with over half of the growth from recent acquisitions, and organic sales up 15% with solid demand across the portfolio.

• Total company net sales growth expected 9% to 11% in 2025.
• Adjusted EBITDA growth expected 8% to 12% in 2025, with margin expansion in both segments.
• Flattish mineral fiber volume for the full year with AUV growth above historical average.
• AS segment organic growth continuing, with acquisitions of 3Form and Zaynor driving growth.
• Capital expenditure slightly higher due to investments in energy-saving ceilings manufacturing capabilities.

• Market uncertainty and choppy market conditions impacting volume and growth.
• Potential tariffs on steel, aluminum, and other materials affecting supply chain costs and pricing.
• Uncertainty in discretionary renovation activity, particularly in the office segment, due to economic and policy factors.

Q: Can you talk more about new products and how they contribute to AUV growth?

A: Our Canopy platform and ProjectWorks drive AUV growth. Canopy has nearly double the average unit value of mineral fiber, and ProjectWorks has five to six times the average unit value. Energy-saving Temploc tiles also contribute with AUV two to three times that of mineral fiber.

Q: How should we model the quarterly cadence for 2025?

A: Mineral fiber volume is expected to be softer in the first half and more favorable in the back half of 2025 due to market uncertainty.

Q: How will tariffs impact WAVE earnings in 2025?

A: Impact on Armstrong is limited. Mineral fiber and architectural specialties are relatively insulated. WAVE has limited exposure to steel and aluminum tariffs, with local sourcing and pricing discipline mitigating impact.

Q: What end-user market is strongest in 2025?

A: Transportation, data centers, healthcare, and education (with state municipal bonds backfilling ESSER funds) are strong end-user markets.
