Southern Star is owned by Cementos Argos S.A., the largest cement producer in Colombia, South America.
Argos acquired full ownership of Southern Star Concrete in November 2005 in a purchase agreement with the former owners, Texas Growth Fund and Austin Ventures, both based in Austin, Texas.
In 2019, Southern Star sold their Arkansas assets to SRM Concrete, a privately-owned materials supply company based out of Nashville, Tennessee.
Then in 2021, Argos sold the Dallas/Fort Worth portion of Southern Star to SRM Concrete.
Argos currently only operates the Houston area Southern Star locations.
