CONSTRUCTION DRIVERS Increased construction activity has driven higher demand for ceramic tile … … but backerboard usage varies significantly by construction segment Higher usage of backerboard in SFNC and R&R segments Lower usage of backerboard in multifamily and commercial segments CAGR = 7.6% CAGR = 28.9% CAGR = 4.0% CAGR = 6.1% Source: U.S. Census Bureau, Home Improvement Research Institute, Catalina Research

TILE VS. BACKERBOARD USAGE Backerboard is prominent solution over wood subfloors Not used over slab on grade SFNC and R&R Lower usage as backerboard is not used over concrete floors Backerboard used on wet area walls Commercial and multifamily While the tile market is split roughly 50/50 for residential vs. commercial applications, the backerboard market is weighted more heavily toward residential Source: Catalina Research, Freedonia INDICATIVE
