Operating EBITDA increased 19% during the fourth quarter of 2020 to US$644 million and increased by 7% for the full year to US$2.46 billion.

CEMEX’s Consolidated Fourth Quarter 2020 Financial and Operational Highlights

“2020 was one of the most challenging years we have faced but it also was a remarkable year that tested the strengths of CEMEX and several of our recent strategic initiatives. I am proud of our performance, the organization, and how we responded to the sudden arrival of COVID-19 in 2020” said Fernando A. González, CEO of CEMEX. “I would like to recognize our employees who have risen to the challenge of COVID and adjusted their protocols to work safely.

Cement volume performance continued to increase in Germany and Czech Republic, but decreased in the UK and Spain as a result of reinstated lockdown measures. Prices in Europe for our three core products in local currency terms, were up between 2% and 3% year-over-year, while cement prices in Egypt and the Philippines declined due to competitive pressures. In the Philippines, we experienced a drop in volumes as the pandemic impacted demand and bad weather hit during the quarter. Despite this, our EBITDA margin in the Philippines went up 2.2 percentage points as a result of successful cost containment efforts. Israel broke volume records once again in the fourth quarter with ready-mix and aggregates experiencing double-digit growth. The country was the fourth largest contributor to consolidated EBITDA for 2020.

EBITDA margin increased 70 basis points mainly due to higher prices, our cost reduction initiatives, and lower fuel prices which were partially offset by higher maintenance costs. In Colombia, construction activity was supported by the residential sector and 4G-highway projects. While industry cement volumes grew in the low-single digits during the quarter, the 7% decline in our cement volumes reflects the entry of capacity by a new competitor in late 2019.
