The success of the stores was such that the project kept growing and Oxxo built new locations rapidly, becoming ubiquitous in Mexican cities and towns.

In 2019, Oxxo Gas aimed to rebrand 49 additional stations, mostly in Monterrey, that were operating under the Pemex name.

[11] In December 2020, the first Oxxo store in Brazil opened under FEMSA's joint venture with Brazilian energy company Raízen.

[12] On August 1, 2024, FEMSA announced plans to acquire 249 DK convenience stores in the U.S. states of Texas, New Mexico, and Arkansas from parent company Delek US Holdings, Inc. for $385 million.

Should the rebrand occur, this would be the second time the Oxxo brand will expand into the U.S. after a short-lived attempt that started back in 2014, with ambitions to open up to 900 stores over the next ten years.
