Nikola Corporation (Nasdaq: NKLA), a global leader in zero-emissions transportation and energy infrastructure solutions, urges all stockholders to vote now FOR Proposal 2 before the Annual Meeting on June 30. Stockholders must vote before the deadline at 11:59 p.m. Eastern Time on June 29, 2022, to ensure their votes are counted.

Approving Proposal 2 is very important. Nikola has 600 million common shares authorized. The combination of fully diluted shares, including shares outstanding and options, restricted stock units and warrants, and reserved/unissued shares from Nikola's equity line of credit and convertible notes means the Company has approximately 567 million fully diluted and reserved/unissued shares, as of June 8, 2022. This leaves Nikola with approximately 33 million shares available for other purposes. That is why we are urging all stockholders to vote NOW FOR Proposal 2, which would allow Nikola to increase the authorized number of shares of the Company's common stock to 800 million, providing flexibility to support the growth of the business.
