LP CEO Curt Stevens tagged the disappointing sales to last winter’s severe weather across most of North America. “The rail transportation systems in both the U.S. and Canada were in disarray in Q1, which caused unplanned downtime at our operations, increased inventory and late shipments and negatively affected our reported results,” he said.
