The CEO highlighted strategic acquisitions, operational efficiency, and digital tools as key growth drivers amid macroeconomic uncertainties.

Mineral Fiber segment net sales increased 6.7% to $267 million, supported by $14 million in favorable average unit value (AUV) and improved sales volumes. Operating income rose 20.4% to $98.4 million, aided by cost reductions and joint venture earnings. The Architectural Specialties segment saw a 37.2% sales jump to $157.6 million, fueled by $28 million from the 2024 acquisitions of 3form and Zahner. Operating income surged 80.3% to $25.6 million, though higher manufacturing and SG&A costs partially offset gains. Both segments contributed to margin expansion, reinforcing the company’s resilience.
