GM walks away from stake in electric vehicle maker Nikola

NEW YORK (AP) — General Motors will not be taking a stake in the electric vehicle company Nikola which announced Monday that it would scuttle one of its marquee vehicles, an electric and hydrogen-powered pickup that was to be called the Badger.

Shares of Nikola plunged 21% at the opening bell.

Nikola on Monday released updated terms between the companies for a supply agreement related to GM's fuel-cell system, replacing an agreement signed in September. That deal would have given GM an 11% stake in Nikola.

The earlier agreement would have allowed Nikola to use GM's new battery electric truck underpinnings for the Badger and its fuel cell and battery technology as well. But that is no longer part of the agreement.

With that end of the partnership now gone, Nikola said Monday that it will begin refunding deposits made by customers who wanted first dibs on the company's pickup truck.

“In a nutshell, the signing of GM as a partner is a positive but ultimately no ownership/equity stake in Nikola and the billions of R&D potentially now off the table is a major negative blow to the Nikola story,” said Wedbush analyst Dan Ives. “This went from a game changer deal for Nikola to a good supply partnership but nothing to write home about.”

However, there were tremors under the potential partnership in late September. GM cast doubt on whether the $2 billion partnership would close as scheduled, saying that discussions with Nikola were ongoing.

That announcement, which sent Nikola shares sliding, came just days after Nikola founder and Chairman Trevor Milton resigned after a Hindenburg Research, a company that's betting Nikola stock will drop, accused Nikola of Fraud. Nikola denies the allegations and called them misleading.

Hindenburg said Nikola's success was an “intricate fraud,” including a video showing a truck rolling downhill to give the impression it was cruising on a highway, and stenciling the words “hydrogen electric” on the side of a vehicle that was actually powered by natural gas.

The Securities and Exchange Commission and the Justice Department are reportedly investigating. GM has said it did proper due diligence before entering the partnership.
