US: USG’s net sales grew by 4% year-on-year to US$3.34bn in 2018 from US$3.20bn in 2017. Its operating profit fell by 36% to US$227m from US$353m. Sales from its wallboard and surfaces division were stable at US$1.93bn but its operating profit fell by 19% to US$248m. The building materials company said that its operating profit in the fourth quarter was negatively affected due to lower sales caused by the timing of when it announced wallboard price increases. USG’s takeover by Germany’s Knauf is expected to close in early 2019.
