Dear Nikola Stockholders,

I am reaching out with an important message regarding Proposal 2, ahead of our Annual Meeting. Thanks to the support of our stockholders, we are getting close to securing the number of votes needed to approve Proposal 2. However, we are still short of the votes needed so don't wait. Vote NOW. You must actively vote before 11:59 p.m. Eastern Time on July 17, 2022. Make your vote count!

Approving Proposal 2 would allow us to increase the authorized number of common shares to 800 million. This is very important as it would allow Nikola greater flexibility to support the future growth and development of our business as we strive to reach new milestones.
