US: Martin Marietta has benefited from aggregate sales volume growth in the first quarter of 2019. Its revenue grew by 17% year-on-year to US$939m from US$802m. Its earnings before interest, taxation, depreciation and amortisation (EBITDA) rose by 28% to US$159m from US$124m. However, the gross profit on its cement business was down and both sales and profit was down for ready-mixed concrete (RMX). Despite this the company said that its cement shipments and pricing increased 7.3% due to demand in Texas, a new Houston-area sales yard and an enhanced product line.
