Nikola Corporation (Nasdaq: NKLA), a global leader in zero-emissions transportation and energy infrastructure solutions, today released a letter to its stockholders urging them to vote in advance of the Company's 2022 Annual Meeting of Stockholders, which will be held virtually on July 18, 2022, at 2:00 p.m. Pacific Time. Additional information can be found at nikolamotor.com/investors.

The full text of the letter follows:

Dear Nikola Stockholders,

On June 30, 2022, we adjourned our 2022 Annual Meeting of Stockholders to allow stockholders additional time to vote on Proposal 2. Voting now remains open until 11:59 p.m., Eastern Time on July 17, 2022, and we urge you to VOTE NOW!

We are getting close – when we adjourned our meeting on June 30, 2022, more than 48% of all outstanding shares had been voted in favor of this proposal, leaving less than 2% of outstanding shares to be voted in favor for this proposal to pass. Because Proposal 2 requires a majority of all outstanding common stock to pass, we still need your support. Every vote matters.

The approval of Proposal 2 would allow us to increase the authorized number of common shares to 800 million, providing flexibility to support our business objectives as we aim to reach new milestones.

VOTE NOW TO SUPPORT NIKOLA:

• By Phone: Please call Alliance Advisors, Nikola's proxy solicitor, toll-free, at (855) 935-2562. International voters can call 1-(207) 607-7123. You can also contact Alliance Advisors if you have any questions about voting.
  • Retail investors, including individual stockholders who purchased shares through app-based brokers, should call the relevant number above.
• By Internet: Vote at www.proxyvote.com using your control number by following the instructions shared by your broker, bank or other nominee.

No further action is required if you have already voted your shares.

ALL stockholders are strongly encouraged to VOTE, no matter how many shares they own. Stockholders as of the close of business on April 4, 2022, should vote their shares even if they no longer own them. The annual meeting will be held virtually on July 18, 2022, at 2:00 p.m. Pacific Time at www.virtualshareholdermeeting.com/NKLA2022 via live audio webcast.

On behalf our entire team and Board of Directors, thank you for your continued support and belief in our company's vision.

Sincerely,

Mark Russell, Chief Executive Officer and President
