Cemex, North America's largest cement producer, reported a 10% increase in quarterly sales on Thursday, boosted by robust demand in the United States and Mexico, despite supply chain interruptions and a spike in energy and transportation costs.

Companies' ability to ship and receive product components and supplies throughout the globe has been disrupted by the COVID-19 outbreak. Cemex warned earlier this month that these difficulties, combined with inflation and foreign exchange effects, might cost the company $100 million in full-year earnings.

Cemex's biggest market, the United States, had net sales rise 10% to $1.12 billion in the third quarter, while sales in Mexico increased 20% to $868 million.

Cemex said its cement and ready-mix businesses in the United States saw a second wave of pricing hikes in the reported quarter, with prices up 2% from the previous three months.

"We are sure that our pricing approach will more than compensate for the unexpected increase in input costs," stated Chief Executive Fernando González.

Cemex lost $376 million in the third quarter, compared to a loss of $1.54 billion the year before.
