Argos USA, a Summit Materials Company

Argos USA comprises the US operations of South American cement producer, Cementos Argos. Its operations include four integrated cement plants, two clinker mills, 140 concrete plants, and a distribution network of eight maritime ports and 10 inland terminals in the Southeast and Mid-Atlantic regions and Texas.

In September 2023, Argos USA merged with Denver based Summit Materials, a leading integrated materials company that supplies aggregates, cement, ready-mixed concrete and asphalt in the US and British Columbia, Canada.

The combined company has presence in 30 US states, with access to ports and terminals that complement domestic production by enabling the import of building materials. Together, Argos USA and Summit make up the fourth largest cement platform in the United States, with an approximate annual production capacity of 11.6 million tons, the sixth largest aggregates platform, with reserves of over 5.5 billion short tons and one of the largest concrete producers, with more than 220 plants and 1,800 mixers.
