Cardtronics Inc. said Monday that it is reorganizing its U.S. operations and their management structure.

The U.S. business of the Houston ATM operator has been split into two groups, one focusing on network and financial services and the other on automated teller machine services.

The groups are led by Rick Updyke, who joined Cardtronics in 2007 with its purchase of 7-Eleven Inc.'s financial services business.

"With this new organizational structure, we are simply looking to realign those talented resources within the company to provide for further visibility into, and responsibility for, the company's key business and strategic initiatives," Steve Rathgaber, Cardtronics' chief executive, said in a press release.

The changes should help Cardtronics "not only achieve, but also exceed its expected revenue and profit growth targets," Rathgaber said.
