MEXICO CITY--Cement maker Cemex SAB reported a net loss for the third quarter on impairment charges related to rising cost inflation and supply-chain disruptions, while sales and operating profit increased from a year before.

The Monterrey, Mexico-based building materials company reported a loss of $376 million for the July to September period, equivalent to 24 U.S. cents an American depositary share, compared with a loss of $1.54 billion for the third quarter of 2020.

Third-quarter sales rose 10% to $3.77 billion thanks to higher volumes and price increases in local currencies.

Cemex reported noncash impairment charges of $500 million for the quarter, mostly in Spain and United Arab Emirates. In the third quarter of 2020, the company recognized impairment costs of $1.5 billion at its U.S. business.

Earnings before interest, taxes, depreciation and amortization rose 2% to $740 million, with growth limited by higher energy and transportation costs. Operating profit increased 3% to $463 million.

Cement sales by volume were little changed from a year earlier at 17.1 million metric tons, while ready mix concrete sales increased 3% to 12.6 million cubic meters and aggregates volume was up 1% at 35.5 million metric tons.

Cemex lowered its full-year Ebitda expectation to $3 billion from its previous $3.1 billion, and reduced its planned capital expenditures for the year to $1.2 billion from $1.3 billion.
