• Maintained strong demand across diverse verticals, including transportation, healthcare, education, and data centers.

Mineral Fiber Operations:

• Achieved fifth consecutive quarter of positive volume growth in five of the last six quarters.
• Canadian customers accelerated purchases ahead of anticipated tariff actions, driving timing-related mix pressure in lower AUV channels.
• Manufacturing teams set all-time records for plant reliability and maintained high perfect order fulfillment levels.
• WAVE joint venture contributed solid earnings, benefiting from data center growth.

Architectural Specialties Operations:

• Broad-based organic growth supported by strong project activity and healthy quoting/order intake rates.
• Recent acquisitions (Eventscape, Parallel, Geometric) contributed to revenue growth; integration is ongoing with strategic rationale proving out.
• Portfolio breadth allows for integrated solutions combining mineral fiber, metal, wood, and design capabilities.
• Highlighted complex project wins, such as the Seattle-Tacoma International Airport Terminal C, showcasing ability to deliver high-design spaces.

Growth Initiatives:

• E-commerce platform Canopy continues double-digit revenue and volume growth, extending beyond mineral fiber.
• Project Works automated design platform aids in pre-construction phases.
• Data center sales (ceiling and Dynamax structural grid) exceeded full-year plans through Q3.
• TempLock energy-saving ceilings gaining specification traction, validated by case studies like the Charlotte pediatric therapy facility.

Mineral Fiber: Net sales increased 7% year-over-year, driven by a 6% increase in Average Unit Value (AUV) and positive volume growth. Adjusted EBITDA grew by 8%, with the adjusted EBITDA margin expanding 40 basis points to 44%. Revenue contribution is not explicitly stated as a percentage of total company revenue in the text, but it is one of two primary operating segments.

Architectural Specialties (AS): Net sales increased 22% year-over-year, including 16% organic growth, the highest quarterly organic growth rate in the segment's history. Adjusted EBITDA increased by 25%, with the adjusted EBITDA margin expanding 60 basis points to 19.4%. On an organic basis, the adjusted EBITDA margin exceeded 20%. Like Mineral Fiber, specific revenue contribution percentages are not provided.

Total Company:

• Net Sales Growth: Raised to 10-11% (from previous 9-11%), driven by robust AS organic performance offset by lower-than-expected acquisition contributions.
• Adjusted EBITDA Growth: Modestly lowered midpoint to 8-10% (from 9-12%), reflecting elevated input cost inflation, tariffs, and acquisition impacts.
• Adjusted Diluted EPS Growth: Lowered to 12-13% (from 12-15%), consistent with EBITDA guidance adjustments.
• Adjusted Free Cash Flow Growth: Lowered to 10-13% (from 10-14%).

Mineral Fiber Segment:

• Net Sales Growth: Slightly lowered to approximately 6.5%, comprising ~1% volume growth and ~5.5% AUV growth.
• Adjusted EBITDA Margin: Expected to be approximately flat year-over-year, impacted by mix headwinds.

Architectural Specialties Segment:

• Net Sales Growth: Raised to 18-19% (from 15-17%), with organic growth expected in the low teens.
• Adjusted EBITDA Margin: Full-year expectation remains approximately 19% reported, with organic margins targeting approximately 20%.

Input Cost Inflation: Rapid acceleration in freight and raw material costs (steel, aluminum) creates timing lags between cost increases and price realization, particularly in custom project-based businesses.

Tariffs and Geopolitical Uncertainty: Anticipated tariff actions affecting grid pricing in Canada caused abnormal buying patterns and mix pressures; ongoing geopolitical uncertainty remains a monitoring point.

Acquisition Integration: Recent acquisitions contribute to higher SG&A and manufacturing costs; one acquisition (Parallel) is ramping slower than expected operationally.

Market Sentiment: While bidding activity is steady, there is cautious sentiment regarding project delays due to elevated interest rates and macroeconomic conditions.

Competitive Environment: The market is highly competitive, requiring continuous innovation, service quality, and specification wins to maintain market share.

Q: Susan McLary asked about customer communication regarding the expanded portfolio value proposition and how the company monitors channel demand changes amidst macro pressures.

A: Mark Hershey explained that the company optimizes its selling organization to engage architects and designers early, offering a complete palette of materials to meet diverse design intents (aesthetics, acoustics, energy). They monitor market insights closely through distribution partners and contractors, leveraging recent high-profile projects like SeaTac Terminal C to reinforce their value proposition in front of the design community.

Q: Tomohiko Sano inquired whether higher rates and costs are impacting customer investment behavior and if there is any pushback on recent pricing actions.

A: Mark Hershey stated that while project counts are muted, project values and bidding activity remain high, indicating sustained demand for premium solutions. Regarding pricing, he emphasized a disciplined, market-based approach where price increases correlate directly with significant input cost inflation (the highest since mid-2022), maintaining credibility with customers rather than facing significant pushback.

Q: Adam Baumgarten asked if mineral fiber AUV assumptions for Q4 would reflect continued mix pressures and if price realization could be higher in 2027 given the inflationary environment.

A: Chris Calzaretta clarified that full-year AUV guidance is 5.5%, expecting stronger pricing due to ongoing inflation but softer mix dynamics. Mark Hershey added that price realization confidence remains high for Q4. For 2027, while no formal guidance is issued yet, the company considers near-to-medium-term inflation outlooks when setting prices, similar to recent increases in June and November.

Q: Keith Hughes asked about the severity of cost pressures in Q4 for both segments and the nature of the pricing lag in Architectural Specialties.

A: Chris Calzaretta confirmed elevated inflation persists into Q4, especially freight and metal costs. Mark Hershey elaborated that AS faces a natural 'lag effect' because pricing is often project-based with longer quote durations. However, mitigating actions (pricing escalators, cost controls) are positioned to drive sequential margin improvement in Q4, countering this lag.

Q: Stephen Kim questioned the specific causes of mix weakness in Mineral Fiber beyond Canada and sought clarification on the timeline for margin rebound in AS.

A: Mark Hershey clarified that the mix pressure was broad-based across all lower AUV channels, not just Canada, combined with slight softness in U.S. commercial channels, though high-end SWAT products still outpaced lower ends. He clarified that the 'moderation by year-end' comment referred specifically to the Canadian dynamic, and the company expects AS margins to expand sequentially in Q4 as mitigation actions take full effect.
