Electric-truck start-up Nikola (NASDAQ: NKLA) announced Monday that it finally has reached a deal with General Motors (NYSE: GM). However, it's a much smaller deal than the one announced in September. Of note, the deal doesn't include Nikola's Badger pickup, which will not be built, Nikola said.

In a statement, Nikola said that the companies have signed a "non-binding Memorandum of Understanding" that outlines a deal in which Nikola would buy hydrogen fuel cells from GM for use in its electric heavy trucks. Nikola said that the companies have also agreed to "discuss" the possibility of using GM's Ultium electric-vehicle batteries in Nikola's trucks.

However, GM will not take an equity stake in Nikola, and it will not engineer and build the Badger electric pickup truck, a pet project of now-departed Nikola founder Trevor Milton. Nikola said that it will refund all of the deposits it had taken for the Badger.

The news comes just a day before the "lockup" on more than 160 million shares held by Nikola insiders expires. About 96 million of those shares, which can be sold starting on Dec. 1, are held by Milton.

In the original deal between Nikola and GM, announced in September, Nikola agreed to buy both batteries and fuel cells from GM, and GM agreed to engineer and build the Badger pickup, with GM taking a $2 billion stake in Nikola.

That deal was announced just a few days before short-seller Hindenburg Research released a scathing report, alleging that Nikola had misled investors about the state of its technology. Nikola's stock fell sharply in the wake of the report, and Milton left the company, throwing the valuation of GM's potential stake — and Nikola's future — into question.
