GM will take an 11 percent ownership stake in the Phoenix-based company and will engineer and build Nikola's Badger hydrogen fuel cell and electric pickup trucks.

The Badger is expected to be in production by the end of 2022.

Nikola will be responsible for the sales and marketing of the Badger, but it will be built on GM's new battery electric truck underpinnings and use GM fuel cell and battery technology.

GM has its own battery electric truck, the GMC Hummer, set to hit the market a full year ahead of the Badger.

GM expects to get more than $4 billion in benefits from the deal with the stock as well as from contracting to manufacture the Badger.

Nikola founder and Executive Chairman Trevor Milton said the agreement relieves his company of the expense of building another factory to make the Badger, which is a little larger than a Chevrolet Silverado.

Wedbush analyst Daniel Ives, in a note to investors Tuesday, wrote that the deal is a huge step forward for Nikola, giving the company credibility with Badger production and its hydrogen fuel cell and semi truck ambitions.
