PHOENIX – July 14, 2022 -- Nikola Corporation (Nasdaq: NKLA), a global leader in zero-emissions transportation and energy infrastructure solutions, strongly urges ALL stockholders to vote IMMEDIATELY for Proposal 2 ahead of the Annual Meeting of Stockholders on July 18, 2022.

With the support of our stockholders, Nikola is now less than 1% short of the outstanding shares needed to be voted in favor for Proposal 2 to pass.

Nikola is getting closer to securing the number of votes needed to approve Proposal 2, but we are not there yet, with only a few days remaining to vote. Every vote matters and all stockholders, regardless of the number of shares they hold, play a critical role in helping Nikola get the additional votes for approval. Cast your vote FOR Proposal 2 NOW, if you have not already.
