OUR SUSTAINABILITY APPROACH

Generally, the Company’s building materials are both sourced and sold locally. As a result, geography is critically
important when assessing market attractiveness and growth opportunities. Attractive geographies generally exhibit
(a) population growth and/or high population density, both of which are drivers of heavy-side building materials
consumption; (b) business and employment diversity, drivers of greater economic stability; and (c) a superior state financial
position, a driver of public infrastructure investment.

Population growth and density are typically assessed based on a site’s proximity to one of the megaregions in the United
States. Megaregions are large networks of metropolitan population centers covering thousands of square miles.
According to America 2050, a planning and policy program of the Regional Plan Association, most of the nation’s
population and economic growth through 2050 will occur in 11 megaregions. The Company has a meaningful presence
in ten megaregions. As evidence of the successful execution of SOAR, the Company’s leading positions in the Texas
Triangle, Colorado’s Front Range, northern and southern California and Arizona’s Sun Corridor megaregions and its
growth platform in the southern portion of the Northeast megaregion are the results of acquisitions since 2011. The
Company’s enhanced positions in the Piedmont Atlantic megaregion and Florida megaregion were expanded with the
Blue Water Industries LLC (BWI Southeast) acquisition completed during 2024. The Company has a legacy presence in the
southeastern portion of the Great Lakes megaregion, encompassing operations in Indiana and Ohio, as well as the Gulf
Coast megaregion in Texas.
