Vote FOR Each Proposal at Nikola’s Annual Meeting of Stockholders

Every vote matters. We ask that you vote FOR each of the proxy proposals to help ensure that Nikola can continue moving forward toward its vision of a zero-emissions future, and toward achieving new milestones.

Your vote “FOR” Proposal 2 is particularly important as it allows us to increase the number of shares of our company's common stock. The passage of this proposal requires more than 50% of our outstanding shares to vote favorably. Every share counts. Every vote counts.

•We will be limited in our ability to raise capital in order to support our ongoing operations and business objectives. We may have to reduce activities or lose important business opportunities, which could negatively affect our performance and our business.

It is imperative for ALL stockholders to VOTE your shares. Stockholders as of the close of business on April 10, 2023, are entitled to vote, even if you no longer own the shares.

If you have any questions, or require assistance with voting, please contact Alliance Advisors at (855) 935-2562.

The deadline to vote is Tuesday, June 6, 2023, at 11:59 p.m. Eastern Time.
