The Chinese companies, who continue to operate mainly in China, again dominated the global cement company rankings in 2019. They account for three of the largest five and six of the largest nine companies when the latter are ranked by capacity. Higher Chinese volumes, and the increased environmental controls which limited production enabling further price increases, led to a further improvement in the Chinese companies profitability. In 2019 Anhui Conch and CNBM had the highest and third highest EBITDAs, with LafargeHolcim in second place. Dangote again had the highest EBITDA margin in 2019, with three of the Chinese companies ranking second, third and fourth.
