The deal and separate reporting could be a foundation for GM to eventually spin off the autonomous vehicle operations, which some analysts have speculated could be valued as much as $30 billion.
Ammann and Barra said the company is focused on safely developing and deploying the self-driving vehicles and declined to directly comment on the possibility of GM Cruise becoming a standalone operation.
“As we move forward, we’re going to evaluate opportunities,” Barra told investors, adding GM will do what’s in the best interest of its shareholders.
A federal filing detailing the SoftBank Vision deal does address the potential for an initial public offering for GM Cruise.
GM, which has touted having all operations under one roof, acquired Cruise Automation in March 2016.
Since then, GM has grown to be considered a leader in the development and deployment of self-driving vehicles along with Google spinoff Waymo. It is predominately testing the self-driving cars in San Francisco as well as Arizona and Michigan. GM previously said testing is expected to expand to New York in 2018.
GM executives on Thursday declined to provide additional details regarding where and when it plans to launch the fleets in 2019.
The automaker is producing the self-driving cars at its Orion Assembly plant in suburban Detroit. It is the only mass-production facility to manufacture such vehicles.
Cruise, from Dec. 1, 2016, to Nov. 30, 2017, drove 131,676 miles on San Francisco’s city streets in 94 Cruise AV cars, which are based on the Chevrolet Bolt EV.
