The Aston Martin Formula One team said it had agreed on an investment by U.S. private equity firm Arctos Partners in exchange for a minority shareholding.
The stake sale, terms of which were not disclosed, values the racing group at 1 billion pounds ($1.24 billion), a person with knowledge about the matter told Reuters.
"They share our vision for our ultraluxury brand, and they are extremely passionate about the sport and its prospects," Aston Martin F1 Executive Chairman Lawrence Stroll said in a statement.
The Formula One team did not provide any further details about the deal.
