Exhibit 99.1

Nikola Corporation Announces Proposed Offerings of Common Stock and Convertible Senior Notes

PHOENIX, December 6, 2023 — Nikola Corporation (Nasdaq: NKLA) today announced its intention to offer, subject to market and other conditions, $100,000,000 of common stock and $200,000,000 aggregate principal amount of Green Convertible Senior Notes due 2026 (the “Notes”) in separate public offerings registered under the Securities Act of 1933, as amended. Nikola also expects to grant the underwriters of the common stock offering a 30-day option to purchase up to an additional $15,000,000 of common stock to cover over-allotments, and expects to grant the underwriters of the Notes offering an option to purchase, for settlement within a period of 13 days from, and including, the date the Notes are first issued, up to an additional $30,000,000 principal amount of Notes to cover over-allotments.

BTIG is acting as lead book-running manager and representative for the offerings. Baird, Bryan, Garnier & Co. and Wolfe | Nomura Alliance are acting as joint book-running managers for the offerings.

The Notes will be senior, unsecured obligations of Nikola, will accrue interest payable semi-annually in arrears and will mature on December 15, 2026, unless earlier repurchased, redeemed or converted. At any time before the close of business on the second scheduled trading day immediately before the maturity date, noteholders may convert their Notes at their option. Nikola will settle conversions by delivering (i) shares of Nikola’s common stock (together, if applicable, with cash in lieu of any fractional share) at the then-applicable conversion rate; and (ii) a cash amount representing the present value of remaining scheduled coupon payments on the converted Notes.

The Notes will be redeemable, in whole or in part (subject to certain limitations), for cash at Nikola’s option at any time, and from time to time, on or after December 15, 2025 and before the maturity date, but only if the last reported sale price per share of Nikola’s common stock exceeds 175% of the conversion price for a specified period of time. The redemption price will be equal to the principal amount of the Notes to be redeemed, plus accrued and unpaid interest, if any, to, but excluding, the redemption date.

If certain corporate events that constitute a “fundamental change” occur prior to the maturity date, then, subject to a limited exception, noteholders may require Nikola to repurchase their Notes for cash. The repurchase price will be equal to the principal amount of the Notes to be repurchased, plus accrued and unpaid interest, if any, to, but excluding, the applicable repurchase date.

The interest rate, initial conversion rate and other terms of the Notes will be determined at the pricing of the Notes offering.

Nikola intends to use the net proceeds from the common stock offering for working capital and other general corporate purposes and allocate an amount equal to the net proceeds from the Notes offering to finance, refinance, or make direct investments in, in whole or in part, one or more new or recently completed (within the 24 months prior to the issue date of the Notes), current or future eligible projects (such projects, “Eligible Green Projects”) in alignment with the guidelines of the Green Bond Principles, 2021 (with June 2022 Appendix I). Pending full allocation of an amount equal to the net proceeds from the offerings to Eligible Green Projects, Nikola may temporarily invest the net proceeds in cash or other short term and liquid instruments, and Nikola will not knowingly invest in operations that result in an overall net increase in greenhouse gas emissions.

The offerings are being made pursuant to an effective shelf registration statement on file with the Securities and Exchange Commission (the “SEC”), which became effective on April 14, 2022 (File No. 333-264068). Each offering will be made only by means of a prospectus supplement relating to that offering and an accompanying prospectus. An electronic copy of the preliminary prospectus supplement for each offering, together with the accompanying prospectus, is available on the SEC’s website at www.sec.gov. Alternatively, copies of each preliminary prospectus supplement, together with the accompanying prospectus, can be obtained by contacting: BTIG, LLC, 600 Montgomery Street, San Francisco, CA 94111 Attention: Syndicate Department (415-248-2200) or by email at prospectusdelivery@btig.com.

This press release does not constitute an offer to sell, or the solicitation of an offer to buy, any securities referred to in this press release, nor will there be any sale of any such securities, in any state or other jurisdiction in which such offer, sale or solicitation would be unlawful prior to registration or qualification under the securities laws of such state or jurisdiction.
