Armstrong World Industries Q3 Earnings Call Highlights

Key Points

• Record Q3 performance: Sales rose 12%, adjusted EBITDA increased 11%, and adjusted diluted EPS grew 10%, with both Mineral Fiber and Architectural Specialties contributing despite inflation, tariffs, and higher freight costs.
• Architectural Specialties led growth: Sales increased 22%, including record 16% organic growth, while adjusted EBITDA rose 25%. Growth was supported by transportation, healthcare, education, data centers, and recent acquisitions.
• Outlook was mixed: Armstrong raised its 2026 sales-growth forecast to 10%–11% but reduced adjusted EBITDA growth guidance to 8%–10% because of inflation, tariffs, and acquisition-related challenges. The company also increased its quarterly dividend 10% and continued substantial share repurchases.

Armstrong World Industries NYSE: AWI reported record third-quarter sales for 2026, with both its Mineral Fiber and Architectural Specialties segments contributing to revenue growth and year-over-year adjusted EBITDA margin expansion. Management said the company’s results were achieved despite rapidly rising freight and raw-material costs, tariff-related pressures and an unfavorable sales mix in certain lower-average-unit-value channels.

Net sales increased 12% from a year earlier, while adjusted EBITDA rose 11% and adjusted diluted earnings per share increased 10%, according to CEO Mark Hershey. He said the company outperformed a largely flat overall market through growth initiatives, pricing, volume gains and broad demand across selected commercial end markets.

“We delivered another solid quarter at Armstrong, demonstrating the resilience of our businesses and continued progress in our growth platforms,” Hershey said.

Mineral Fiber Sales Rise as Canada Demand Affects Mix

Mineral Fiber segment sales increased 7% in the third quarter, driven by 6% average unit value, or AUV, growth and higher volumes. CFO Chris Calzaretta said favorable like-for-like pricing was the principal AUV contributor, along with a positive mix contribution.

Volume growth marked the segment’s third consecutive quarter of gains and the fifth growth quarter in the past six periods. Demand was supported by the company’s growth initiatives and by timing-related buying from Canadian customers ahead of anticipated tariff actions affecting ceiling grid pricing. Because Armstrong sells complete ceiling systems, the grid activity also generated additional Mineral Fiber demand.

However, the Canadian activity was concentrated in lower-AUV channels and reduced the margin benefit normally associated with the sales increase. Hershey said the company views the mix effect as timing-related and expects it to moderate by the end of the year.

Mineral Fiber adjusted EBITDA increased 8%, and its adjusted EBITDA margin expanded 40 basis points to 44%. Calzaretta said the result was the segment’s strongest third-quarter margin since 2019, despite accelerating inflation in freight and raw materials. The segment also benefited from a solid contribution from the WAVE joint venture and lower selling, general and administrative expenses compared with a prior-year period that had higher incentive compensation expense.

Management said WAVE benefited from higher commercial and Canadian volume as well as data center sales, although the Canadian timing benefit is expected to ease in the fourth quarter.

Architectural Specialties Posts Record Organic Growth

Architectural Specialties sales climbed 22%, including 16% organic growth, the segment’s highest quarterly organic growth rate on record. Growth was broad-based across specialty categories and supported by project activity in transportation, healthcare, education and other commercial applications.

Recent acquisitions also contributed to growth, including Eventscape, acquired in February, and the 2025 acquisitions of Parallel and Geometrik. Architectural Specialties adjusted EBITDA rose 25%, while adjusted EBITDA margin increased 60 basis points to 19.4%.

On an organic basis, the segment generated an adjusted EBITDA margin above 20%, Calzaretta said, despite higher freight, aluminum and steel costs. Higher sales provided a $12 million EBITDA benefit, including $3 million from acquired businesses, though increased manufacturing and SG&A costs partially offset the gain.

Hershey said the company continues to see a path toward its 20% adjusted EBITDA margin target for Architectural Specialties as it integrates and scales acquired businesses. He said Parallel has ramped more slowly than expected operationally, with the company seeking better throughput and operating leverage, while the other two recent acquisitions are generally performing in line with expectations.

Order intake in Architectural Specialties increased at a double-digit rate for another quarter, management said. Hershey attributed the performance partly to Armstrong’s broader portfolio of mineral fiber, metal, wood, felt and structural systems, which enables the company to pursue more specifications and provide integrated project solutions.

Inflation Prompts Pricing and Cost Actions

Management said input-cost inflation accelerated during the third quarter at the fastest pace the company has experienced since mid-2022. For the full year, Armstrong now expects total input cost inflation at the high end of the mid-single-digit range. Freight inflation is expected to be about 20% above the prior year, while energy and raw material costs are expected to remain in the low-single-digit range.

Armstrong has responded through pricing actions, productivity measures, spending controls and transportation optimization. Hershey said the company uses market-based pricing correlated to inflation, while Calzaretta noted that pricing realization can lag sudden cost increases.

The lag is particularly relevant in Architectural Specialties, where much of the business is priced on custom projects with quotes that may remain in force until expiration or until escalation provisions take effect. Management nevertheless expects Architectural Specialties margin improvement both sequentially and year over year in the fourth quarter.

• Mineral Fiber announced an additional price increase effective in November.
• Architectural Specialties implemented off-cycle pricing actions in June and November.
• WAVE also enacted additional price increases in June and November.

Updated 2026 Outlook and Capital Returns

Armstrong modestly raised its full-year sales outlook, now expecting total company revenue growth of 10% to 11%, compared with its prior range of 9% to 11%. The increase reflects stronger-than-expected organic performance in Architectural Specialties.

The company now expects Architectural Specialties revenue growth of 18% to 19%, up from prior guidance of 15% to 17%, while Mineral Fiber sales are expected to grow about 6.5%, including approximately 1 percentage point of volume growth and roughly 5.5% AUV growth.

At the same time, Armstrong lowered its adjusted EBITDA growth forecast to 8% to 10%, from 9% to 12%, citing elevated inflation, tariffs, the timing of mitigation actions and lower-than-expected contributions from recent acquisitions. The company expects Mineral Fiber’s full-year adjusted EBITDA margin to be approximately flat with the prior year’s record 43.5%, while Architectural Specialties is expected to produce an adjusted EBITDA margin of about 19%, or approximately 20% organically.

Adjusted diluted EPS growth is now forecast at 12% to 13%, compared with prior guidance of 12% to 15%. Adjusted free cash flow growth is projected at 10% to 13%, versus the earlier 10% to 14% outlook.

The company increased its quarterly dividend by 10%, its eighth consecutive annual dividend increase since the program began in 2018. During the third quarter, Armstrong paid $15 million in dividends and repurchased $75 million of stock. Through Sept. 30, it had paid $45 million in dividends and repurchased $210 million of shares, with more than $1 billion remaining under its authorization.

Management said it remains encouraged by activity in transportation, healthcare and data centers. Through the third quarter, ceiling and DYNAMAX structural-grid data center sales had exceeded the company’s full-year revenue plans, Hershey said, while Kanopi and ProjectWorks continued to add growth in Mineral Fiber volumes and support the company’s broader digital and design capabilities.
