Item 2. Properties

We own a 100-acre, multi-building campus in Lancaster, Pennsylvania comprising the site of our corporate headquarters and most of our non-manufacturing operations.

As of December 31, 2025, we operated 22 manufacturing plants, including 19 plants located within the U.S. and three plants in Canada.

WAVE operates seven additional plants in the U.S. to produce suspension system (grid) products, which we use and sell in our ceiling systems.

Fourteen of our plants are leased and the remaining eight are owned.

Operating SegmentNumber ofPlantsLocation of Principal Facilities
Mineral Fiber5U.S. (Florida, Georgia, Ohio, Pennsylvania and West Virginia)
Architectural Specialties17U.S. (California (3), Colorado, Illinois (2), Missouri (2), Ohio (3), North Carolina, Texas, Utah) and Canada (British Columbia, Ontario and Quebec)

Sales and administrative offices are leased and/or owned, and leased facilities are used to supplement our owned warehousing facilities.

Production capacity and the extent of utilization of our facilities are difficult to quantify with certainty. In any one facility, utilization of our capacity varies periodically depending upon demand for the product that is being manufactured. We believe our facilities are adequate and suitable to support the business. Additional incremental investments in plant facilities are made as appropriate to balance capacity with anticipated demand, improve quality and service, and reduce costs.
