PROSPECTUS SUPPLEMENT SUMMARY

This summary highlights certain information contained in or incorporated by reference in this prospectus supplement and the accompanying prospectus about us, the public offering and the concurrent direct offering. Because it is a summary, it does not contain all of the information that you should consider before investing. Before investing in our common stock, you should read this entire prospectus supplement and the accompanying prospectus carefully, including the “Risk Factors” section beginning on page S-6 herein and in the accompanying prospectus, our Annual Report on Form 10-K for the year ended December 31, 2022, and other information incorporated by reference in this prospectus supplement and the accompanying prospectus.

Our Company

We are a technology innovator and integrator, working to develop innovative energy and transportation solutions. We are pioneering a business model that is intended to enable corporate customers to integrate next generation truck technology, hydrogen fueling and charging infrastructure, and related maintenance. By creating this ecosystem, we and our strategic business partners and suppliers expect to build a long-term competitive advantage for clean technology vehicles and next generation fueling solutions.

We believe our expertise lies in design, innovation, software, and engineering. We assemble, integrate, and commission our vehicles in collaboration with our business partners and suppliers. Our approach has always been to leverage strategic partnerships to help lower cost, increase capital efficiency and accelerate speed to market.

Concurrent Direct Offering

Concurrently with the public offering, we have entered into the Purchase Agreement with the Investor, pursuant to which the Investor has agreed to purchase up to $100.0 million of shares of our common stock in a registered direct offering. Under the terms of the Purchase Agreement, the Investor will purchase up to $100.0 million of our common stock, with the actual amount of shares of common stock to be purchased in the concurrent direct offering to be reduced by the extent of the total public offering amount. In the event that the total public offering amount in the public offering is at least $100.0 million, the Investor will not purchase any shares of common stock in the concurrent direct offering. The public offering is not contingent on the closing of the concurrent direct offering, and the concurrent direct offering is not contingent on the closing of the public offering. If shares of common stock are sold in each of the public offering and the concurrent direct offering, they will be sold at the public offering price. If any shares are sold in the concurrent direct offering, such shares are expected to be delivered on or after April 11, 2023.

As of March 28, 2023, the maximum number of shares of common stock issuable to the Investor upon conversion of the 8.00%/11.00% convertible senior paid-in-kind, or PIK, toggle notes due 2026, or the Notes, held by Investor, including shares underlying the maximum principal amount of the Notes potentially issuable as PIK interest payments thereon, was 43,217,169 shares or approximately 7.3% of our outstanding common stock as of March 28, 2023. The number of shares issuable assumes the potential maximum “make-whole” adjustment to the initial conversion rate of 114.3602 shares per $1,000 principal amount of the Notes, as adjusted, the initial maximum conversion rate, and that we elect physical settlement for all conversions of the Notes. The initial conversion rate is subject to adjustment under certain circumstances described in the indenture, dated as of June 1, 2022, among us, the guarantors named therein and U.S. Bank Trust Company, National Association, as trustee, as amended pursuant to a supplemental indenture thereto to be entered into in connection with the Exchange (as defined below), or the Indenture. As a result, the maximum number of shares of common stock issuable upon conversion of the Notes may increase or decrease in the future.

After giving effect to the consummation of the concurrent direct offering at an assumed public offering price of $1.50 per share, which is the last reported sale price of our common stock on Nasdaq on March 29, 2023 (assuming the Investor purchases the full $100.0 million of common stock under the Purchase Agreement), the

S-2

Investor would beneficially own 66,666,666 shares of common stock, which represents approximately 11.3% of our common stock outstanding as of March 28, 2023. The amount set forth above does not include 83,150,899 shares of common stock underlying the Notes and the Series B Notes (as defined below) that would be outstanding immediately after giving effect to the Exchange (assuming that all of the Notes and the Series B Notes were converted at such time at their respective initial maximum conversion rates (assuming that the initial maximum conversion rate for the Series B Notes is established off the public offering price)) or any shares of common stock potentially issuable in respect of any PIK interest payments thereon, which are not convertible into common stock until we obtain the necessary stockholder approval, including an increase in our authorized common stock. Assuming such stockholder approval were obtained, the Investor would beneficially own an aggregate of 149,817,565 shares of common stock representing approximately 25.3% of our common stock outstanding as of March 28, 2023.

Exchange of Notes

On March 29, 2023, we entered into an exchange and investment agreement, or the Exchange Agreement, with the Investor to exchange $100.0 million aggregate principal amount of the Notes for the same amount of 8.00% / 11.00% series B convertible senior PIK toggle notes due 2026, or the Series B Notes, with an initial conversion price equal to 130% of the public offering price. The Series B Notes will not be convertible until the earlier of six months from the issue date and the date on which the necessary stockholder approval is obtained. In connection with the Exchange, the Indenture governing the Notes will be amended to, among other things, (i) remove the requirement that we reserve shares of common stock for conversion of the Notes until we receive stockholder approval to increase the number of our authorized shares and (ii) provide for the same restrictions on conversion as the Series B Notes. The closing of the Exchange is not contingent upon the closing of the public offering or the direct offering.

Recent Developments

We had approximately $123 million of cash and $85 million of restricted cash as of March 28, 2023. Our potential capital includes gross proceeds of $100 million (before giving effect to the underwriting discounts and commissions and estimated offering expenses payable by us) from the public offering and the concurrent direct offering and approximately 67.8 million shares of common stock available for issuance after the public offering and the concurrent direct offering. The number of shares available after the public offering and the concurrent direct offering includes approximately 92.2 million shares of authorized and unissued common stock available prior to the public offering and the concurrent direct offering and approximately 43.2 million previously reserved shares of common stock to be released as part of the Exchange, and assumes the public offering is priced at a price of $1.48 per share, the last reported sale price of our common stock on Nasdaq on March 28, 2023. Cash and shares available after the public offering and the concurrent direct offering has not been adjusted for approximately 1.6 million shares to be issued after March 28, 2023.

On June 3, 2020, VectoIQ consummated a business combination with Nikola Corporation, a Delaware corporation, or Legacy Nikola, and, in connection therewith, (i) VectoIQ’s wholly-owned subsidiary merged with and into Legacy Nikola, whereby Legacy Nikola survived the merger and was deemed the accounting predecessor of the merger and became the successor registrant for SEC purposes and (ii) we changed our name to “Nikola Corporation.” Upon consummation of the foregoing transactions, Legacy Nikola became our wholly-owned subsidiary.

RISK FACTORS

Investing in our common stock involves a high degree of risk. Before making an investment decision, you should carefully consider the risks described below and under the section titled “Risk Factors” in our most recent Annual Report on Form 10-K incorporated by reference in this prospectus supplement and the accompanying prospectus, any amendment or update thereto reflected in our subsequent filings with the SEC, and all of the other information in this prospectus supplement and the accompanying prospectus, including our financial statements and related notes incorporated by reference in this prospectus supplement and the accompanying prospectus. If any of these risks is realized, our business, financial condition, results of operations and prospects could be materially and adversely affected. In that event, the trading price of our common stock could decline and you could lose part or all of your investment. Additional risks and uncertainties that are not yet identified or that we think are immaterial may also materially harm our business, operating results and financial condition and could result in a complete loss of your investment.

Risks Related to the Offerings

Purchasers in the public offering will experience immediate and substantial dilution in the book value of their investment.

Purchasers of our common stock in the public offering will experience immediate dilution in the net tangible book value of the common stock purchased in the public offering because the price per share of common stock in the public offering is substantially higher than the net tangible book value per share of our common stock outstanding immediately after the public offering. Based on an assumed public offering price of $1.50 per share, which is the last reported sale price of our common stock on Nasdaq on March 29, 2023, and after deducting the estimated underwriting discounts and commissions and estimated offering expenses payable by us, our adjusted net tangible book value as of December 31, 2022, would have been approximately $522.4 million, or approximately $0.90 per share of our common stock. As a result, if you purchase shares of common stock in the public offering, you would suffer immediate and substantial dilution of $0.60 per share with respect to the net tangible book value of the common stock. See “Dilution” in this prospectus supplement for a detailed discussion of the dilution you will incur if you purchase shares in the public offering.

We will have broad discretion in how we use the net proceeds of the public offering and the concurrent direct offering. We may not use these proceeds effectively, which could affect our results of operations and cause our stock price to decline.

Although we currently intend to use the net proceeds from the public offering and the concurrent direct offering in the manner described in the section entitled “Use of Proceeds” in this prospectus supplement, we will have considerable discretion in the application of the net proceeds of the public offering and the concurrent direct offering. We may use the net proceeds for purposes that do not yield a significant return or any return at all for our stockholders. In addition, pending their use, we may invest the net proceeds from the public offering in a manner that does not produce income or that loses value. If we do not invest or apply the net proceeds from the public offering in ways that enhance stockholder value, we may fail to achieve expected financial results, which could cause our stock price to decline.

If we raise additional capital in the future, your ownership in us could be diluted.

Any issuance of equity we may undertake in the future to raise additional capital could cause the price of our common stock to decline, or require us to issue shares at a price that is lower than that paid by holders of our common stock in the past, which would result in those newly issued shares being dilutive. If we obtain funds through a credit facility or through the issuance of debt or preferred securities, these securities would likely have rights senior to your rights as a stockholder, which could impair the value of our common stock.

S-6

We have never paid dividends on our capital stock, and we do not anticipate paying dividends in the foreseeable future.

We have never paid dividends on any of our capital stock and currently intend to retain any future earnings to fund the growth of our business. Any determination to pay dividends in the future will be at the discretion of our board of directors, and will depend on our financial condition, operating results, capital requirements, general business conditions and other factors that our board of directors may deem relevant. As a result, capital appreciation, if any, of our common stock will be the sole source of gain for the foreseeable future.

Sales of a substantial number of shares of our common stock in the public market or in the concurrent direct offering could cause the price of our common stock to decline.

Sales of a substantial number of shares of our common stock in the public market, in the concurrent direct offering, or the perception that these sales might occur could depress the market price of our common stock and could impair our ability to raise capital through the sale of additional equity securities. We are unable to predict the effect that sales may have on the prevailing market price of our common stock. In addition, the sale of substantial amounts of our common stock could adversely impact its price. As of December 31, 2022, we had outstanding 512,935,485 shares of common stock, options to purchase 22,470,585 shares of common stock, warrants to purchase an aggregate of 1,388,266 shares of common stock, and 21,491,780 shares underlying RSUs granted pursuant to the 2020 Stock Plan. We also had up to 3,420,990 shares of common stock that may be issued to Tumim pursuant to the Tumim Purchase Agreements, up to 31,343,074 shares of common stock issuable upon conversion of approximately $210.9 million original aggregate principal amount of the Notes, and up to 11,874,095 shares of common stock underlying the maximum principal amount of Notes potentially issuable as PIK interest payments on the Notes, in each case, at the initial maximum conversion rate for the Notes, up to 154,078 shares of common stock underlying RSUs and performance-related stock units in connection with our acquisition of Romeo and 1,511,771 shares available for future issuance under the Nikola Corporation 2022 Inducement Plan and the Romeo Incentive Plan. In addition, the foregoing excludes shares issued after December 31, 2022. All of the shares of our common stock are freely transferable, subject to in certain cases compliance with Rule 144 by affiliates. We have also registered shares of our common stock that we have issued and may in the future issue under our employee equity incentive plans or pursuant to the Equity Distribution Agreement. These shares may be sold freely in the public market upon issuance, subject to relevant vesting schedules, and applicable securities laws. In addition, we have in the past and may in the future issue equity securities as consideration for various types of corporate transactions, including acquisitions, strategic partnerships and licensing transactions, which results in dilution to our existing stockholders and may result in additional sales of our common stock. Sales of a substantial number of shares of our common stock in the public market or the perception that these sales might occur could depress the market price of our common stock and could impair our ability to raise capital through the sale of additional equity securities. We are unable to predict the effect that sales may have on the prevailing market price of our common stock. In addition, the sale of substantial amounts of our common stock could adversely impact its price.

We will be unable to issue sufficient additional shares for future capital raising transactions, including pursuant to existing potential sources of capital, or strategic transactions, unless we obtain stockholder approval to amend our certificate of incorporation to increase the number of authorized shares of our common stock available for issuance.

We operate in a capital-intensive industry. We do not believe we currently have sufficient unissued shares of common stock for future issuances to raise funds necessary to execute on our business plan. As of December 31, 2022, we were authorized to issue 800,000,000 shares of common stock. Having additional authorized shares of common stock available is critical to our continued efforts to pursue our strategic goals and we will be limited by the number of shares available for future capital raising transactions, including pursuant to the Equity Distribution Agreement, the Second Tumim Purchase Agreement, the securities purchase agreement related to our senior convertible notes, and agreements we may enter into in the future, or for business development

S-7

transactions or acquisitions, unless we obtain stockholder approval of an amendment to our restated certificate of incorporation to increase the number of authorized shares of our common stock. We intend to solicit the approval of our stockholders to amend our restated certificate of incorporation to increase the number of authorized shares of our common stock at our annual meeting of stockholders in June 2023, but we have in the past encountered difficulties obtaining stockholder approval for similar proposals and there can be no assurance that our stockholders will approve the contemplated amendment or any future amendment, particularly since we have a large retail stockholder base. A delay in securing, or a failure to secure, stockholder approval to amend our restated certificate of incorporation could cause a delay in our future capital raising, including pursuant to existing financing agreements, collaboration, partnership or other strategic transactions, and would have a material adverse effect on our business, prospects, operations, liquidity and financial condition.

Our liquidity may be significantly impaired if we do not obtain stockholder approval to increase the authorized number of our shares of common stock.

After giving effect to the Exchange, the indenture that will govern the Series B Notes will limit our ability to settle conversions thereof with shares of our common stock. As a result, we will have to settle all or a portion of such conversions with cash. Consequently, such conversions could significantly impair cash available for general corporate purposes, including our working capital needs.

USE OF PROCEEDS

We estimate that the net proceeds to us from the public offering (assuming the full $100.0 million of common stock is sold pursuant to the public offering, and no shares are sold pursuant to the concurrent direct offering), after deducting the underwriting discounts and commissions and estimated offering expenses payable by us, will be approximately $95.7 million in the aggregate.

A $1.00 increase or decrease in the assumed public offering price of $1.50 per share, which is the last reported sale price of our common stock on Nasdaq on March 29, 2023, would increase or decrease the net proceeds to us from the public offering by approximately $66.7 million, assuming that the number of shares offered by us, remains the same and after deducting the estimated underwriting discounts and commissions and estimated offering expenses payable by us. We may also increase or decrease the aggregate amount of the shares we are offering in the public offering. Similarly, a 1.0 million share increase or decrease in the number of shares offered by us would increase or decrease the net proceeds to us by $1.5 million, assuming that the assumed public offering price of $1.50 per share remains the same and after deducting the estimated underwriting discounts and commissions and estimated offering expenses payable by us. The net proceeds information discussed above is illustrative only. The net proceeds to us from the public offering is subject to adjustment based on the actual public offering price of our shares and other terms of the public offering determined at pricing.

We currently intend to use the net proceeds from the public offering and the concurrent direct offering for working capital and general corporate purposes. Accordingly, we will retain broad discretion over the use of these proceeds. Pending application of the net proceeds as described above, we intend to invest the net proceeds in short- and intermediate-term, interest-bearing obligations, investment-grade instruments, certificates of deposit or direct or guaranteed obligations of the U.S. government.

DESCRIPTION OF COMMON STOCK

This section describes the general terms and provisions of the shares of our common stock. This description is only a summary. Our restated certificate of incorporation, or our Certificate of Incorporation, and our amended and restated bylaws, or our Bylaws, have been filed as exhibits to our periodic reports filed with the SEC, which are incorporated by reference into the prospectus and this prospectus supplement. You should read our Certificate of Incorporation and our Bylaws for additional information before you invest in our common stock. See “Where You Can Find More Information.”

Authorized and Outstanding Common Stock

Our Certificate of Incorporation authorizes the issuance of 800,000,000 shares of common stock, $0.0001 par value per share. As of March 28, 2023, there were 592,435,146 shares of common stock issued and outstanding, and as of March 27, 2023, there were 141 holders of record of our common stock. Because many of our shares of common stock are held by brokers and other nominees on behalf of stockholders, this number is not indicative of the total number of stockholders represented by these stockholders of record.

Common Stock

Voting Power

Except as otherwise required by law or as otherwise provided in any certificate of designation for any series of preferred stock, the holders of common stock possess all voting power for the election of our directors and all other matters requiring stockholder action. Holders of common stock are entitled to one vote per share on matters to be voted on by stockholders.

Dividends

Holders of outstanding shares of our common stock will be entitled to receive such dividends, if any, as may be declared from time to time by our board of directors in its discretion out of funds legally available therefor. In no event will any stock dividends or stock splits or combinations of stock be declared or made on common stock unless the shares of common stock at the time outstanding are treated equally and identically. We have not paid any cash dividends to date. We may retain future earnings, if any, for future operations, expansion and debt repayment and have no current plans to pay cash dividends for the foreseeable future. Any decision to declare and pay dividends in the future will be made at the discretion of the board and will depend on, among other things, our results of operations, financial condition, cash requirements, contractual restrictions and other factors that the board may deem relevant. In addition, our ability to pay dividends may be limited by covenants of future outstanding indebtedness we or our subsidiaries incur.

Liquidation, Dissolution and Winding Up

In the event of our voluntary or involuntary liquidation, dissolution, distribution of assets or winding-up, the holders of the common stock will be entitled to receive an equal amount per share of all of our assets of whatever kind available for distribution to stockholders, after the rights of the holders of the preferred stock have been satisfied.

Preemptive or Other Rights

Holders of our common stock have no preemptive, conversion or other subscription rights, and there are no sinking fund or redemption provisions applicable to our common stock.

Election of Directors

Our board of directors is divided into three classes, each of which will generally serve for a term of three years with only one class of directors being elected in each year. There is no cumulative voting with respect to

S-13

the election of directors, with the result that the holders of more than 50% of the shares voted for the election of directors can elect all of the directors.

Registration Rights

On June 3, 2020, we entered into a Registration Rights and Lock-Up Agreement with certain of our stockholders, or the Holders. Pursuant to the terms of the Registration Rights and Lock-Up Agreement, subject to certain requirements and customary conditions, including with regard to the number of demand rights that may be exercised, the Holders may demand at any time or from time to time, that the Company file a registration statement on Form S-3 (or on Form S-1 if Form S-3 is not available) to register the Company’s securities held by such Holders. The Registration Rights and Lock-Up Agreement will also provide the Holders with “piggy-back” registration rights, subject to certain requirements and customary conditions.

On September 24, 2021, we entered into a common stock purchase agreement with Tumim Stone Capital LLC, or Tumim, pursuant to which Tumim committed to purchase up to $300.0 million of our common stock. In connection with such purchase agreement, we also entered into a registration rights agreement with Tumim to register for resale under the Securities Act the shares of our common stock that have been and may be issued to Tumim under the purchase agreement.

We generally must pay all expenses relating to any such registrations, other than underwriting discounts and selling commissions. The terms of the registration rights are specified in the relevant registration rights agreement.

Certain Provisions of Delaware Law and Our Certificate of Incorporation and Bylaws

Certain provisions of Delaware law, our Certificate of Incorporation and our Bylaws, described below, may have the effect of delaying, deferring or discouraging another party from acquiring control of us.

Special Meetings of Stockholders

Our Certificate of Incorporation provides that special meetings of our stockholders may be called by such persons as provided in our Bylaws. Our Bylaws provide that special meetings of our stockholders may be called only by (i) a majority vote of our board of directors, (ii) our Secretary, at the request of the Chairman of our board, (iii) our executive chairman, or (iv) the vote of the stockholders owning not less than 25% of our issued and outstanding stock; provided that our board of directors approves such stockholder request for a special meeting.

Advance Notice Requirements for Stockholder Proposals and Director Nominations

Our Bylaws provide that stockholders seeking to bring business before our annual meeting of stockholders, or to nominate candidates for election as directors at our annual meeting of stockholders, must provide timely notice of their intent in writing. To be timely under our Bylaws, a stockholder’s notice will need to be received by the company secretary at our principal executive offices not later than the close of business on the 90th day nor earlier than the open of business on the 120th day prior the anniversary of the date of our proxy statement provided in connection with the previous year’s annual meeting of stockholders; provided, however, that in the event that no annual meeting was held in the previous year or the annual meeting is called for a date that is more than 30 days before or after the anniversary date of the previous year’s annual meeting, notice by the stockholder must be received by the secretary no later than the close of business on the latter of the 90th day prior to such annual meeting and the 10th day following the day on which public announcement of the date of such meeting is first made. Our Certificate of Incorporation and our Bylaws specify certain requirements as to the form and content of a stockholders’ meeting. These provisions may preclude our stockholders from bringing matters before our annual meeting of stockholders or from making nominations for directors at our annual meeting of stockholders.

S-14

Authorized but Unissued Shares

Our authorized but unissued common stock and preferred stock are available for future issuances without stockholder approval and could be utilized for a variety of corporate purposes, including future offerings to raise additional capital, acquisitions and employee benefit plans. The existence of authorized but unissued and unreserved common stock and preferred stock could render more difficult or discourage an attempt to obtain control of us by means of a proxy contest, tender offer, merger or otherwise.

Exclusive Forum Selection

Our Certificate of Incorporation requires, to the fullest extent permitted by law, that derivative actions brought in our name, actions against directors, officers and employees for breach of fiduciary duty and other similar actions be brought in the Court of Chancery in the State of Delaware or, if that court lacks subject matter jurisdiction, another federal or state court situated in the State of Delaware. Any person or entity purchasing or otherwise acquiring any interest in shares of our capital stock shall be deemed to have notice of and consented to the forum provisions in our Certificate of Incorporation. Our Certificate of Incorporation also requires the federal district courts of the United States shall be the exclusive forum for the resolution of any complaint asserting a cause of action under the Securities Act and the Exchange Act, and the stockholder bringing the suit will be deemed to have to service of process on such stockholder’s counsel. Although we believe these provisions benefit us by providing increased consistency in the application of Delaware law in the types of lawsuits to which it applies, a court may determine that these provisions are unenforceable, and to the extent they are enforceable, the provisions may have the effect of discouraging lawsuits against our directors and officers, although our stockholders will not be deemed to have waived our compliance with federal securities laws and the rules and regulations thereunder.

Section 203 of the Delaware General Corporation Law

We are subject to the provisions of Section 203 of the General Corporation Law of the State of Delaware, or the DGCL, regulating corporate takeovers. In general, Section 203 prohibits a publicly-held Delaware corporation from engaging, under certain circumstances, in a business combination with an interested stockholder for a period of three years following the date that such stockholder became an interested stockholder unless:

• prior to the date of the transaction, the board of directors of the corporation approved either the business combination or the transaction which resulted in the stockholder becoming an interested stockholder; upon completion of the transaction that resulted in the stockholder becoming an interested stockholder, the interested stockholder owned at least 85% of the voting stock of the corporation outstanding at the time the transaction commenced, excluding for purposes of determining the voting stock outstanding, but not the outstanding voting stock owned by the interested stockholder, (1) shares owned by persons who are directors and also officers and (2) shares owned by employee stock plans in which employee participants do not have the right to determine confidentially whether shares held subject to the plan will be tendered in a tender or exchange offer; or

• at or subsequent to the date of the transaction, the business combination is approved by the board of directors of the corporation and authorized at an annual or special meeting of stockholders, and not by written consent, by the affirmative vote of at least 66 2/3% of the outstanding voting stock which is not owned by the interested stockholder.

Generally, Section 203 defines a “business combination” to include a merger, asset or stock sale, or other transaction resulting in a financial benefit to the “interested stockholder,” and an “interested stockholder” as a person who, together with affiliates and associates, owns or, within three years prior to the determination of interested stockholder status, did own 15% or more of a corporation’s outstanding voting stock. We expect the existence of this provision to have an anti-takeover effect with respect to transactions our board of directors does not approve in advance. We also anticipate that Section 203 may discourage business combinations or other

S-15

attempts that might result in a premium over the market price for the shares of common stock held by our stockholders. A Delaware corporation may opt out of these provisions either with an express provision in its original certificate of incorporation or in an amendment to its certificate of incorporation or bylaws approved by its stockholders. However, we have not opted out, and do not currently intend to opt out of, these provisions.

Certain of the provisions of the DGCL, our Certificate of Incorporation and our Bylaws could have the effect of discouraging others from attempting hostile takeovers and, as a consequence, they may also inhibit temporary fluctuations in the market price of our common stock that often result from actual or rumored hostile takeover attempts. These provisions may also have the effect of preventing changes in our management. It is possible that these provisions could make it more difficult to accomplish transactions that stockholders may otherwise deem to be in their best interests.

Limitation on Liability and Indemnification of Directors and Officers

Our Certificate of Incorporation limits our directors’ liability to the fullest extent permitted under the DGCL. The DGCL provides that directors of a corporation will not be personally liable for monetary damages for breach of their fiduciary duties as directors, except for liability:

• for any transaction from which the director derives an improper personal benefit;

• for any act or omission not in good faith or that involves intentional misconduct or a knowing violation of law;

• for any unlawful payment of dividends or redemption of shares; or

• for any breach of a director’s duty of loyalty to the corporation or its stockholders.

Delaware law and our Certificate of Incorporation provide that we will, in certain situations, indemnify our directors and officers and may indemnify other employees and other agents, to the fullest extent permitted by law. Any indemnified person is also entitled, subject to certain limitations, to advancement, direct payment, or reimbursement of reasonable expenses (including attorneys’ fees and disbursements) in advance of the final disposition of the proceeding.

In addition, we have entered into indemnification agreements with our directors and officers. These agreements, among other things, require us to indemnify our directors and officers for certain expenses, including attorneys’ fees, judgments, fines, and settlement amounts incurred by a director or officer in any action or proceeding arising out of their services as one of our directors or officers or any other company or enterprise to which the person provides services at our request.

We maintain a directors’ and officers’ insurance policy pursuant to which our directors and officers are insured against liability for actions taken in their capacities as directors and officers. We believe these provisions in our Certificate of Incorporation and our Bylaws and these indemnification agreements are necessary to attract and retain qualified persons as directors and officers.

Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers, or control persons, in the opinion of the SEC, such indemnification is against public policy as expressed in the Securities Act and is therefore unenforceable.

DILUTION

If you purchase our common stock in the public offering, your ownership interest will be immediately diluted to the extent of the difference between the public offering price per share and the net tangible book value per share of our common stock immediately after the public offering. Net tangible book value per share is determined by dividing the number of shares of common stock outstanding as of December 31, 2022 into our total tangible assets less total liabilities.

Our net tangible book value as of December 31, 2022 was approximately $426.7 million, or $0.83 per share, based on 512,935,485 shares of our common stock outstanding as of that date. After giving effect to the sale by us of 66,666,666 shares of common stock by us at the public offering price of $1.50 per share in the public offering, the last reported sale price of our common stock on Nasdaq on March 29, 2023, and assuming no shares are sold in the concurrent direct offering, and after deducting the underwriting discounts and commissions and estimated offering expenses payable by us, our as adjusted net tangible book value as of as of December 31, 2022 would have been approximately $522.4 million, or $0.90 per share. This represents an immediate increase in net tangible book value of $0.07 per share to existing stockholders and immediate dilution of $0.60 per share to investors in the public offering, as illustrated by the following table:

Assumed public offering price per share			$	1.50
Net tangible book value per share as of December 31, 2022	$	0.83
Increase in net tangible book value per share attributable to investors purchasing shares in the public offering		0.07
As adjusted net tangible book value per share after giving effect to the public offering				0.90
Dilution per share to investors in the public offering			$	0.60

A $1.00 increase or decrease in the assumed public offering price of $1.50 per share, the last reported sale price of our common stock on Nasdaq on March 29, 2023, would increase or decrease our as adjusted net tangible book value by approximately $0.04 per share, and the dilution per share to investors in the public offering by approximately $0.96 per share, assuming that the number of shares offered by us, as set forth above, remains the same and after deducting the estimated underwriting discounts and commissions and estimated offering expenses payable by us. We may also increase or decrease the aggregate amount of the shares we are offering in the public offering. A 1.0 million share increase or decrease in the number of shares offered by us would not have a material impact on our as adjusted net tangible book value or the dilution per share to investors in this offering, assuming that the assumed public offering price of $1.50 per share remains the same and after deducting the estimated underwriting discounts and commissions and estimated offering expenses payable by us. The as adjusted information discussed above is illustrative only. Our net tangible book value following the completion of the public offering is subject to adjustment based on the actual public offering price of our shares and other terms of the public offering determined at pricing.

If the underwriters exercise in full their option to purchase up to $15.0 million of additional shares from us at an assumed public offering price of $1.50 per share, the last reported sale price of our common stock on Nasdaq on March 29, 2023, the as adjusted net tangible book value per share after the public offering would be $0.91 per share, the increase in net tangible book value per share to existing stockholders would be $0.08 per share and the dilution to new investors purchasing shares in the public offering would be $0.59 per share. The foregoing tables and calculations (other than net tangible book value calculations) are based on 512,935,485 shares outstanding as of December 31, 2022 and excludes:

• 22,470,585 shares of common stock issuable upon the exercise of outstanding options granted under the 2017 Option Plan, with a weighted-average exercise price of $1.31 per share;

S-17

• 11,395,450 shares available for future issuance under the 2020 Stock Plan;

• 4,000,000 shares available for future issuance under the 2020 ESPP;

• 21,491,780 shares underlying RSUs granted pursuant to the 2020 Stock Plan;

• 760,915 shares issuable upon the exercise of outstanding warrants to purchase common stock, with an exercise price of $11.50 per share;

• 376,935 shares issuable upon the exercise of outstanding warrants to purchase common stock, with an exercise price of $96.96 per share;

• 250,416 shares issuable upon the exercise of outstanding warrants to purchase common stock, with a weighted average exercise price of $39.68 per share;

• up to 32,211,777 shares of common stock that are registered and may be issued to Tumim pursuant to the Tumim Purchase Agreements;

• up to 31,343,074 shares of common stock issuable upon conversion of approximately $210.9 million original aggregate principal amount of the Notes, and up to 11,874,095 shares of common stock underlying the maximum principal amount of Notes potentially issuable as PIK interest payments on the Notes, in each case, at the initial maximum conversion rate for the Notes;

• up to 154,078 shares of common stock underlying RSUs and performance-related stock units in connection with our acquisition of Romeo; and

• 1,511,771 shares available for future issuance under the Nikola Corporation 2022 Inducement Plan and the Romeo Incentive Plan.

The shares outstanding as of December 31, 2022 referenced above also excludes shares of common stock issued after December 31, 2022 but before March 24, 2023, including but not limited to:

• 17,020,258 shares of common stock issued pursuant to the Equity Distribution Agreement;

• 27,372,316 shares of common stock issued to Tumim pursuant to the Tumim Purchase Agreements; and

• 28,366,433 shares of common stock issued upon conversion of our $50.0 million series A senior convertible notes and $25.0 million series B-1 senior convertible notes.

The foregoing also does not include shares of common stock issued on or after March 24, 2023, including but not limited to, shares of common stock to be issued pursuant to the Second Tumim Purchase Agreement and additional shares of common stock that may be issued upon conversion of our $25.0 million series B-1 senior convertible notes.

MATERIAL U.S. FEDERAL INCOME TAX CONSEQUENCES TO NON-U.S. HOLDERS

The following is a general discussion of the material U.S. federal income tax considerations applicable to non-U.S. holders (as defined herein) with respect to their ownership and disposition of shares of our common stock issued pursuant to the public offering. All prospective non-U.S. holders of our common stock should consult their own tax advisors with respect to the U.S. federal, state, local and non-U.S. tax consequences of the purchase, ownership and disposition of our common stock. In general, a non-U.S. holder means a beneficial owner of our common stock (other than a partnership or an entity or arrangement treated as a partnership for U.S. federal income tax purposes) that is not, for U.S. federal income tax purposes:

• an individual who is a citizen or resident of the United States;

• a corporation, or an entity treated as a corporation for U.S. federal income tax purposes, created or organized in the United States or under the laws of the United States or of any state thereof or the District of Columbia;

• an estate, the income of which is subject to U.S. federal income tax regardless of its source; or

• a trust if (1) a U.S. court can exercise primary supervision over the trust’s administration and one or more U.S. persons have the authority to control all of the trust’s substantial decisions or (2) the trust has a valid election in effect under applicable U.S. Treasury Regulations to be treated as a U.S. person.

This discussion is based on current provisions of the U.S. Internal Revenue Code of 1986, as amended, which we refer to as the Code, existing U.S. Treasury Regulations promulgated thereunder, published administrative pronouncements and rulings of the U.S. Internal Revenue Service, which we refer to as the IRS, and judicial decisions, all as in effect as of the date of this prospectus supplement. These authorities are subject to change and to differing interpretation, possibly with retroactive effect. Any change or differing interpretation could alter the tax consequences to non-U.S. holders described in this prospectus supplement and the accompanying prospectus.

We assume in this discussion that a non-U.S. holder holds shares of our common stock as a capital asset within the meaning of Section 1221 of the Code (generally, for investment). This discussion does not address all aspects of U.S. federal income taxation that may be relevant to a particular non-U.S. holder in light of that non-U.S. holder’s individual circumstances, nor does it address any estate or gift tax consequences, or any aspects of U.S. state, local or non-U.S. taxes. This discussion also does not consider any specific facts or circumstances that may apply to a non-U.S. holder and does not address the special tax rules applicable to particular non-U.S. holders, such as holders that own, or are deemed to own, more than 5% of our capital stock (except to the extent specifically set forth below), corporations that accumulate earnings to avoid U.S. federal income tax, tax-exempt organizations, banks, financial institutions, insurance companies, brokers, dealers or traders in securities, commodities or currencies, tax-qualified retirement plans, holders subject to the alternative minimum tax or the Medicare contribution tax on net investment income, holders that are subject to the special tax accounting rules of Section 451(b) of the Code, holders who hold or receive our common stock pursuant to the exercise of employee stock options or otherwise as compensation, holders holding our common stock as part of a hedge, straddle or other risk reduction strategy, conversion transaction or other integrated investment, holders deemed to sell our common stock under the constructive sale provisions of the Code, controlled foreign corporations, passive foreign investment companies, disregarded entities and certain former U.S. citizens or long-term residents.

In addition, this discussion does not address the tax treatment of partnerships (or entities or arrangements that are treated as partnerships for U.S. federal income tax purposes) or partners in such partnerships. If a partnership, including any entity or arrangement treated as a partnership for U.S. federal income tax purposes, holds shares of our common stock, the U.S. federal income tax treatment of a partner in such partnership will generally depend upon the status of the partner and the activities of the partnership. Such partners and partnerships should consult their tax advisors regarding the tax consequences of the purchase, ownership and disposition of our common stock.

S-19

We have not obtained, nor do we intend to obtain, a ruling with respect to the U.S. federal income tax consequences to a non-U.S. holder of the purchase, ownership or disposition of our common stock and there can be no assurance that a court or the IRS will not challenge one or more of the tax consequences described herein.

Distributions on our common stock

Distributions, if any, on our common stock generally will constitute dividends for U.S. federal income tax purposes to the extent paid from our current or accumulated earnings and profits, as determined under U.S. federal income tax principles. If a distribution exceeds our current and accumulated earnings and profits, the excess will be treated as a tax-free return of the non-U.S. holder’s investment, up to such holder’s adjusted tax basis in the common stock. Any remaining excess will be treated as capital gain from the sale or exchange of such common stock, subject to the tax treatment described below in “Gain on sale, exchange or other disposition of our common stock.” Any such distribution also will be subject to the discussion below under the heading “FATCA withholding.”

Dividends paid to a non-U.S. holder generally will be subject to withholding of U.S. federal income tax at a 30% rate of the gross amount of dividends or such lower rate as may be specified by an applicable income tax treaty between the United States and such holder’s country of residence.

Dividends that are treated as effectively connected with a trade or business conducted by a non-U.S. holder within the United States and, if an applicable income tax treaty so provides, that are attributable to a permanent establishment or a fixed base maintained by the non-U.S. holder within the United States, generally are exempt from the 30% withholding tax if the non-U.S. holder satisfies applicable certification and disclosure requirements. However, such U.S. effectively connected income, net of specified deductions and credits, is taxed at the same U.S. federal income tax rates applicable to United States persons (as defined in the Code, which we refer to as U.S. persons). Any U.S. effectively connected income received by a non-U.S. holder that is a corporation may also, under certain circumstances, be subject to an additional “branch profits tax” at a 30% rate or such lower rate as may be specified by an applicable income tax treaty between the United States and such holder’s country of residence.

To claim a reduction of or exemption from withholding, a non-U.S. holder of our common stock generally will be required to provide (a) a properly executed IRS Form W-8BEN or W-8BEN-E (or successor form) and satisfy applicable certification and other requirements to claim the benefit of an applicable income tax treaty between the United States and such holder’s country of residence, or (b) a properly executed IRS Form W-8ECI stating that dividends are not subject to withholding because they are effectively connected with such non-U.S. holder’s conduct of a trade or business within the United States. Non-U.S. holders should consult their tax advisors regarding their entitlement to benefits under a relevant income tax treaty.

A non-U.S. holder that is eligible for a reduced rate of U.S. withholding tax under an income tax treaty may obtain a refund or credit of any excess amounts withheld by timely filing an appropriate claim for refund with the IRS.

Gain on sale, exchange or other disposition of our common stock

Subject to the discussion below regarding backup withholding and FATCA withholding, in general, a non-U.S. holder will not be subject to any U.S. federal income tax on any gain realized upon such holder’s sale, exchange or other disposition of shares of our common stock unless:

• the gain is effectively connected with a U.S. trade or business of the non-U.S. holder and, if an applicable income tax treaty so provides, is attributable to a permanent establishment or a fixed base maintained in the United States by such non-U.S. holder, in which case the non-U.S. holder generally will be taxed at the same U.S. federal income tax rates applicable to U.S. persons and, if the non-U.S. holder is a foreign corporation, the branch profits tax described above in “Distributions on our common stock” also may apply;

S-20

• the non-U.S. holder is a nonresident alien individual who is present in the United States for 183 days or more in the taxable year of the disposition and certain other conditions are met, in which case the non-U.S. holder will be subject to a 30% tax (or such lower rate as may be specified by an applicable income tax treaty) on the net gain derived from the disposition, which may be offset by U.S. source capital losses of the non-U.S. holder, if any (even though the individual is not considered a resident of the United States), provided that the non-U.S. holder has timely filed U.S. federal income tax returns with respect to such losses; or

• our common stock constitutes a U.S. real property interest because we are, or have been, at any time during the five-year period preceding such disposition (or the non-U.S. holder’s holding period, if shorter) a “U.S. real property holding corporation.” Generally, a corporation is a U.S. real property holding corporation only if the fair market value of its U.S. real property interests equals or exceeds 50% of the sum of the fair market value of its worldwide real property interests plus its other assets used or held for use in a trade or business. Although there can be no assurance, we do not believe that we are, and do not anticipate becoming, a U.S. real property holding corporation. Even if we are or become a U.S. real property holding corporation, provided that our common stock is regularly traded, as defined by applicable Treasury Regulations, on an established securities market, our common stock will be treated as a U.S. real property interest only with respect to a non-U.S. holder that holds more than 5% of our outstanding common stock, directly or indirectly, actually or constructively, during the shorter of the 5-year period ending on the date of the disposition or the period that the non-U.S. holder held our common stock. In such case, such non-U.S. holder generally will be taxed on its net gain derived from the disposition at the graduated U.S. federal income tax rates applicable to U.S. persons. No assurance can be provided that our common stock will be or continue to be regularly traded on an established securities market for purposes of the rules described above.

Information reporting and backup withholding

We must report annually to the IRS and to each non-U.S. holder the gross amount of the distributions on our common stock paid to such holder (whether or not such distributions constitute dividends) and the tax withheld, if any, with respect to such distributions. Non-U.S. holders will have to comply with specific certification procedures to establish that the holder is not a U.S. person (as defined in the Code) in order to avoid backup withholding at the applicable rate with respect to dividends on our common stock. A non-U.S. holder generally will not be subject to U.S. backup withholding with respect to payments of dividends on our common stock if it certifies its non-U.S. status by providing a valid IRS Form W-8BEN or W-8BEN-E (or successor form) or W-8ECI, or otherwise establishes an exemption; provided that we do not have actual knowledge or reason to know such non-U.S. holder is a U.S. person. Dividends paid to non-U.S. holders that are subject to the U.S. withholding tax, as described above in “Distributions on our common stock,” generally will be exempt from U.S. backup withholding.

Information reporting and backup withholding will generally apply to the proceeds of a disposition of our common stock by a non-U.S. holder effected by or through the U.S. office of any broker, U.S. or foreign, unless the holder certifies its status as a non-U.S. holder and satisfies certain other requirements, or otherwise establishes an exemption. Generally, information reporting and backup withholding will not apply to a payment of disposition proceeds to a non-U.S. holder where the transaction is effected outside the United States through a non-U.S. office of a broker. However, for information reporting purposes, dispositions effected through a non-U.S. office of a broker with substantial U.S. ownership or operations generally will be treated in a manner similar to dispositions effected through a U.S. office of a broker. Non-U.S. holders should consult their tax advisors regarding the application of the information reporting and backup withholding rules to them.

Copies of information returns may be made available to the tax authorities of the country in which the non-U.S. holder resides or is incorporated under the provisions of a specific treaty or agreement.

S-21

Backup withholding is not an additional tax. Any amounts withheld under the backup withholding rules from a payment to a non-U.S. holder may be allowed as a credit against the non-U.S. holder’s U.S. federal income tax liability, if any, and may entitle such holder to a refund, provided that the required information is timely furnished to the IRS.

FATCA withholding

The Code, U.S. Treasury Regulations and other applicable guidance, commonly referred to as “FATCA”, generally impose a U.S. federal withholding tax of 30% on dividends on stock in a U.S. corporation paid to (i) a “foreign financial institution” (as specifically defined for this purpose), unless such institution enters into an agreement with the U.S. government to, among other things, withhold on certain payments and to collect and provide to the U.S. tax authorities substantial information regarding U.S. account holders of such institution (which includes certain equity and debt holders of such institution, as well as certain account holders that are foreign entities with U.S. owners) or otherwise qualifies for an exemption from these rules, or (ii) a non-financial foreign entity (as defined in the Code), unless such entity provides the withholding agent with either a certification that it does not have any substantial direct or indirect U.S. owners or provides information regarding substantial direct and indirect U.S. owners of the entity, or otherwise qualifies for an exemption from these rules. Proposed Treasury Regulations (upon which taxpayers and withholding agents are entitled to rely) eliminate possible FATCA withholding on the gross proceeds from a sale or other disposition of our common stock. Under certain circumstances, a non-U.S. holder might be eligible for refunds or credits of such taxes. An intergovernmental agreement between the United States and an applicable foreign country may modify the requirements described in this paragraph.

Investors are encouraged to consult with their tax advisors regarding the implications of FATCA to their particular circumstances.

EACH PROSPECTIVE INVESTOR SHOULD CONSULT ITS TAX ADVISORS REGARDING THE PARTICULAR U.S. FEDERAL, STATE AND LOCAL AND NON-U.S. TAX CONSEQUENCES OF THE PURCHASE, OWNERSHIP AND DISPOSITION OF OUR COMMON STOCK, INCLUDING THE CONSEQUENCES OF ANY PROPOSED CHANGE IN APPLICABLE LAWS.

S-22

CONCURRENT DIRECT OFFERING

On March 29, 2023, we entered into the Purchase Agreement with the Investor, pursuant to which the Investor has agreed to purchase up to $100.0 million of shares of our common stock in a registered direct offering. Under the terms of the Purchase Agreement, the Investor will purchase up to $100.0 million of our common stock, with the actual amount of shares of common stock to be purchased in the concurrent direct offering to be reduced by the extent of the total public offering amount from the public offering.

We expect to raise no less than $100.0 million of gross proceeds from either the public offering or the concurrent direct offering, or a combination thereof. For example, in the event that the total public offering amount is at least $100.0 million from the public offering, the Investor will not purchase any shares of common stock in the concurrent direct offering. If we do not raise any proceeds from the public offering, the Investor has committed to purchase up to $100.0 million of shares of our common stock under the Purchase Agreement. The public offering is not contingent on the closing of the concurrent direct offering, and the concurrent direct offering is not contingent on the closing of the public offering. If shares of common stock are sold in each of the public offering and the concurrent direct offering, they will be sold at the public offering price.

The Purchase Agreement can be terminated (i) by mutual agreement of us and the Investor, (ii) by either party if the underwriting agreement between us and Citigroup Global Markets Inc. is terminated in accordance with its terms without the public offering being consummated, (iii) by us if we determine not to consummate the public offering or (iv) by the Investor if the concurrent direct offering does not close by April 13, 2023. The Purchase Agreement contains customary representations and warranties. The obligation of the Investor to purchase our shares are also subject to the conditions precedent in the Purchase Agreement.

The concurrent direct offering is expected to close on or after April 11, 2023.

As of March 28, 2023, the maximum number of shares of common stock issuable to the Investor upon conversion of the Notes held by Investor, including shares underlying the maximum principal amount of the Notes potentially issuable as PIK interest payments thereon, was 43,217,169 shares or approximately 7.3% of our outstanding common stock as of March 28, 2023. The number of shares issuable assumes the potential maximum “make-whole” adjustment to the initial conversion rate of 114.3602 shares per $1,000 principal amount of the Notes, as adjusted, the initial maximum conversion rate, and that we elect physical settlement for all conversions of the Notes. The initial conversion rate is subject to adjustment under certain circumstances described in the Indenture. As a result, the maximum number of shares of common stock issuable upon conversion of the Notes may increase or decrease in the future.

After giving effect to the consummation of the concurrent direct offering at an assumed public offering price of $1.50 per share, which is the last reported sale price of our common stock on Nasdaq on March 29, 2023 (assuming the Investor purchases the full $100.0 million of common stock under the Purchase Agreement), the Investor would beneficially own 66,666,666 shares of common stock, which represents approximately 11.3% of our common stock outstanding as of March 28, 2023. The amount set forth above does not include 83,150,899 shares of common stock underlying the Notes and the Series B Notes that would be outstanding immediately after giving effect to the Exchange (assuming that all of the Notes and the Series B Notes were converted at such time at their respective initial maximum conversion rates (assuming that the initial maximum conversion rate for the Series B Notes is established off the public offering price)) or any shares of common stock potentially issuable in respect of any PIK interest payments thereon, which are not convertible into common stock until we obtain the necessary stockholder approval, including an increase in our authorized common stock. Assuming such stockholder approval were obtained, the Investor would beneficially own an aggregate of 149,817,565 shares of common stock representing approximately 25.3% of our common stock outstanding as of March 28, 2023.

S-23

On March 29, 2023, we entered into the Exchange Agreement with the Investor to exchange $100.0 million aggregate principal amount of the Notes for the same amount of Series B Notes, with an initial conversion price equal to 130% of the public offering price.

Citigroup Global Markets Inc., or the placement agent, is acting as exclusive placement agent in connection with the concurrent direct offering. In connection with its services as placement agent for the concurrent direct offering, the placement agent will receive a fee equal to 3.75% of the gross proceeds from the shares of common stock sold in the concurrent direct offering. We have also granted the placement agent a right of first refusal for a period of one (1) year following October 25, 2022, to act as book-running lead managing underwriter or book-running lead arranger in connection with any “underwritten” Rule 144A offering, underwritten public offering or other financing that may be undertaken by us, on terms and conditions customary for similar transactions. We have also agreed to indemnify the placement agent against certain liabilities in connection with the concurrent direct offering.

S-24

If the underwriter exercises this option, it will be obligated, subject to specified conditions, to purchase the number of additional shares it elects to purchase.

The closing of the concurrent direct offering, if any, will occur subsequent to the closing of the public offering. The public offering is not contingent on the closing of the concurrent direct offering, and the concurrent direct offering is not contingent on the closing of the public offering.

S-28

Citigroup Global Markets Inc., in its sole discretion, may release the common stock and other securities subject to the lock-up agreements described above in whole or in part at any time.

Stabilization

In order to facilitate the public offering of the common stock, the underwriter may engage in transactions that stabilize, maintain or otherwise affect the price of the common stock. Specifically, the underwriter may sell more shares than it is obligated to purchase under the underwriting agreement, creating a short position. A short sale is covered if the short position is no greater than the number of shares available for purchase by the underwriter under the option to purchase additional shares. The underwriter can close out a covered short sale by exercising the option to purchase additional shares or purchasing shares in the open market. In determining the source of shares to close out a covered short sale, the underwriter will consider, among other things, the open market price of shares compared to the price available under the option to purchase additional shares. The underwriter may also sell shares in excess of the option to purchase additional shares, creating a naked short position. The underwriter must close out any naked short position by purchasing shares in the open market. A naked short position is more likely to be created if the underwriter is concerned that there may be downward pressure on the price of the common stock in the open market after pricing that could adversely affect investors who purchase in the public offering. As an additional means of facilitating the public offering, the underwriter may bid for, and purchase, shares of common stock in the open market to stabilize the price of the common stock. These activities may raise or maintain the market price of the common stock above independent market levels or prevent or retard a decline in the market price of the common stock. The underwriter is not required to engage in these activities and may end any of these activities at any time.

We and the underwriter have agreed to indemnify each other against certain liabilities, including liabilities under the Securities Act.

Electronic Distribution

In connection with the public offering, the underwriter or certain securities dealers may distribute prospectuses by electronic means, such as e-mail. In addition, the underwriter may facilitate Internet distribution for the public offering to certain of its Internet subscription customers. The underwriter may allocate a limited number of shares for sale to its online brokerage customers. A prospectus in electronic format is being made available on an Internet web site maintained by the underwriter. Other than the prospectus in electronic format, the information on the underwriter’s web site and any information contained in any other web site maintained by the underwriter is not part of the prospectus or the registration statement of which the prospectus forms a part.

Other Relationships

The underwriter and certain of its affiliates are full service financial institutions engaged in various activities, which may include securities trading, commercial and investment banking, financial advisory, investment management, investment research, principal investment, hedging, financing, and brokerage activities. The underwriter and certain of its affiliates have, from time to time, performed, and may in the future perform, various commercial, financial advisory and investment banking services for us and our affiliates, for which they received or will receive customary fees and expenses. In particular, the underwriter is acting as placement agent in connection with the concurrent direct offering and will receive customary fees in connection with its services. See “Concurrent Direct Offering” for more information.

In addition, in the ordinary course of their various business activities, the underwriter and certain of its affiliates may make or hold a broad array of investments and actively trade debt and equity securities (or related derivative securities) and financial instruments (including bank loans) for their own account and for the accounts of their customers, and may at any time hold long and short positions in such securities and instruments. Such investment and securities activities may involve securities and/or instruments issued by us and our affiliates. The

S-29

underwriter and its affiliates may also make investment recommendations or publish or express independent research views in respect of such securities or instruments and may at any time hold, or recommend to clients that they acquire, long and/or short positions in such securities and instruments.

DESCRIPTION OF DEBT SECURITIES

The following is a summary of the general terms of the debt securities. We will file a prospectus supplement that may contain additional terms when we issue debt securities. The terms presented here, together with the terms in a related prospectus supplement, together with any pricing supplement or term sheet, will be a description of the material terms of the debt securities.

We may issue, from time to time, debt securities, in one or more series. These debt securities that we may issue include senior debt securities, senior subordinated debt securities, subordinated debt securities, convertible debt securities and exchangeable debt securities. The debt securities we offer will be issued under an indenture between us and the trustee named in the indenture. The following is a summary of the material provisions of the form of indenture filed as an exhibit to the registration statement of which this prospectus is a part. All capitalized terms have the meanings specified in the indenture. For each series of debt securities, the applicable prospectus supplement for the series may change and supplement the summary below.

As used in this section only, “we,” “us” and “our” refer to Nikola Corporation excluding our subsidiaries, unless expressly stated or the context otherwise requires.

General Terms of the Indenture

The indenture does not limit the amount of debt securities that we may issue. It provides that we may issue debt securities for any series of debt securities up to the principal amount that we may authorize. Except for the limitations on consolidation, merger and sale of all or substantially all of our assets contained in the indenture, the terms of the indenture do not contain any covenants or other provisions designed to give holders of any debt securities protection against changes in our operations, financial condition or transactions involving us. For each series of debt securities, any restrictive covenants for those debt securities will be described in the applicable prospectus supplement for those debt securities.

We may issue the debt securities issued under the indenture as “discount securities,” which means they may be sold at a discount below their stated principal amount. These debt securities, as well as other debt securities that are not issued at a discount, may, for United States federal income tax purposes, be treated as if they were issued with “original issue discount,” or OID, because of interest payment and other characteristics. Special United States federal income tax considerations applicable to debt securities issued with original issue discount will be described in more detail in any applicable prospectus supplement.

You should refer to the prospectus supplement relating to a particular series of debt securities for a description of the following terms of the debt securities offered by that prospectus supplement and by this prospectus:

• the title of those debt securities;

• any limit on the aggregate principal amount of that series of debt securities;

• the date or dates on which principal and premium, if any, of the debt securities of that series is payable;

• the interest rate or rates (which may be fixed or variable) or the method used to determine the rate or rates, and the date or dates from which interest, if any, on the debt securities of that series will accrue, and the dates when interest is payable and related record dates;

• the right, if any, to extend the interest payment periods and the duration of the extensions;

• if the amount of payments of principal or interest is to be determined by reference to an index or formula, or based on a coin or currency other than that in which the debt securities are stated to be payable, the manner in which these amounts are determined and the calculation agent, if any, with respect thereto;

6

• the place or places where and the manner in which principal, premium, if any, and interest, if any, on the debt securities of that series will be payable and the place or places where those debt securities may be presented for transfer and, if applicable, conversion or exchange;

• the period or periods within which, the price or prices at which and other terms and conditions upon which those debt securities may be redeemed, in whole or in part, at our option or the option of a holder of those securities, if we or a holder is to have that option;

• our obligation or right, if any, to redeem, repay or purchase those debt securities pursuant to any sinking fund or analogous provision or at the option of a holder of those securities, and the terms and conditions upon which the debt securities will be redeemed, repaid or purchased, in whole or in part, pursuant to that obligation;

• the terms, if any, on which the debt securities of that series will be subordinate in right and priority of payment to our other debt;

• the denominations in which those debt securities will be issuable;

• if other than the entire principal amount of the debt securities when issued, the portion of the principal amount payable upon acceleration of maturity as a result of a default on our obligations;

• whether any securities of that series are to be issued in whole or in part in the form of one or more global securities and the depositary for those global securities;

• if the principal of or any premium or interest on the debt securities of that series is to be payable, or is to be payable at our election or the election of a holder of those securities, in securities or other property, the type and amount of those securities or other property, or the manner of determining that amount, and the period or periods within which, and the terms and conditions upon which, any such election may be made;

• the events of default and covenants relating to the debt securities that are in addition to, modify or delete those described in this prospectus;

• conversion or exchange provisions, if any, including conversion or exchange prices or rates and adjustments thereto;

• whether and upon what terms the debt securities may be defeased, if different from the provisions set forth in the indenture;

• the nature and terms of any security for any secured debt securities;

• the terms applicable to any debt securities issued at a discount from their stated principal amount; and

• any other specific terms of any debt securities.

The applicable prospectus supplement will present material United States federal income tax considerations for holders of any debt securities and the securities exchange or quotation system on which any debt securities are to be listed or quoted.

Conversion or Exchange Rights

Debt securities may be convertible into or exchangeable for shares of our equity securities or other securities. The terms and conditions of conversion or exchange will be stated in the applicable prospectus supplement. The terms will include, among others, the following:

• the conversion or exchange price;

• the conversion or exchange period;

• provisions regarding our ability or the ability of any holder to convert or exchange the debt securities;

• events requiring adjustment to the conversion or exchange price; and

• provisions affecting conversion or exchange in the event of our redemption of the debt securities.

7

Consolidation, Merger or Sale

We cannot consolidate with or merge with or into, or transfer or lease all or substantially all of our assets to, any person, unless we are the surviving corporation or the successor person is a corporation organized under the laws of the United States, any state of the United States or the District of Columbia and expressly assumes our obligations under the debt securities and the indenture. In addition, we cannot complete such a transaction unless immediately after completing the transaction, no event of default under the indenture, and no event that, after notice or lapse of time or both, would become an event of default under the indenture, has occurred and is continuing. When the successor person has assumed our obligations under the debt securities and the indenture, we will be discharged from all our obligations under the debt securities and the indenture except in limited circumstances.

This covenant would not apply to any recapitalization transaction, a change of control affecting us or a highly leveraged transaction, unless the transaction or change of control were structured to include a merger or consolidation or transfer or lease of all or substantially all of our assets.

Events of Default

The indenture provides that the following will be “events of default” with respect to any series of debt securities:

• failure to pay interest for 30 days after the date payment is due and payable;

• failure to pay principal or premium, if any, on any debt security when due, either at maturity, upon any redemption, by declaration or otherwise and, in the case of technical or administrative difficulties, only if such default persists for a period of more than three business days;

• failure to make sinking fund payments when due and continuance of such default for a period of 30 days;

• failure to perform other covenants for 60 days after notice that performance was required;

• certain events in bankruptcy, insolvency or reorganization relating to us; or

• any other event of default provided in the applicable officer’s certificate, resolution of our board of directors or the supplemental indenture under which we issue a series of debt securities.

An event of default for a particular series of debt securities does not necessarily constitute an event of default for any other series of debt securities issued under the indenture. For each series of debt securities, any modifications to the above events of default will be described in the applicable prospectus supplement for those debt securities.

The indenture provides that if an event of default specified in the first, second, third, fourth or sixth bullets above occurs and is continuing, either the trustee or the holders of at least 25% in aggregate principal amount of the outstanding debt securities of that series may declare the principal amount of all those debt securities (or, in the case of discount securities or indexed securities, that portion of the principal amount as may be specified in the terms of that series) to be due and payable immediately. If an event of default specified in the fifth bullet above occurs and is continuing, then the principal amount of all those debt securities (or, in the case of discount securities or indexed securities, that portion of the principal amount as may be specified in the terms of that series) will be due and payable immediately, without any declaration or other act on the part of the trustee or any holder. In certain cases, holders of a majority in principal amount of the outstanding debt securities of any series may, on behalf of holders of all those debt securities, rescind and annul a declaration of acceleration.

The indenture imposes limitations on suits brought by holders of debt securities against us. Except for actions for payment of overdue principal or interest, no holder of debt securities of any series may institute any action against us under the indenture unless:

• the holder has previously given to the trustee written notice of default and continuance of such default;

8

• the holders of at least 25% in principal amount of the outstanding debt securities of the affected series have requested that the trustee institute the action;

• the requesting holders have offered the trustee indemnity for the reasonable expenses and liabilities that may be incurred by bringing the action;

• the trustee has not instituted the action within 60 days of the request and offer of indemnity; and

• the trustee has not received inconsistent direction by the holders of a majority in principal amount of the outstanding debt securities of the affected series.

We will be required to file annually with the trustee a certificate, signed by one of our officers, stating whether or not the officer knows of any default by us in the performance, observance or fulfillment of any condition or covenant of the indenture.

Discharge, Defeasance and Covenant Defeasance

We can discharge or decrease our obligations under the indenture as stated below.

We may discharge obligations to holders of any series of debt securities that have not already been delivered to the trustee for cancellation and that have either become due and payable or are by their terms to become due and payable, or are scheduled for redemption, within one year. We may effect a discharge by irrevocably depositing with the trustee cash or government obligations denominated in the currency of the debt securities, as trust funds, in an amount certified to be enough to pay when due, whether at maturity, upon redemption or otherwise, the principal of, and any premium and interest on, the debt securities and any mandatory sinking fund payments.

Unless otherwise provided in the applicable prospectus supplement, we may also discharge any and all of our obligations to holders of any series of debt securities at any time, which we refer to as defeasance. We may also be released from the obligations imposed by any covenants of any outstanding series of debt securities and provisions of the indenture, and we may omit to comply with those covenants without creating an event of default under the trust declaration, which we refer to as covenant defeasance. We may effect defeasance and covenant defeasance only if, among other things:

• we irrevocably deposit with the trustee cash or government obligations denominated in the currency of the debt securities, as trust funds, in an amount certified to be enough to pay at maturity, or upon redemption, the principal (including any mandatory sinking fund payments) of, and any premium and interest on, all outstanding debt securities of the series; and

• we deliver to the trustee an opinion of counsel from a nationally recognized law firm to the effect that the holders of the series of debt securities will not recognize income, gain or loss for U.S. federal income tax purposes as a result of the defeasance or covenant defeasance and that defeasance or covenant defeasance will not otherwise alter the holders’ U.S. federal income tax treatment of principal, and any premium and interest payments on, the series of debt securities.

In the case of a defeasance by us, the opinion we deliver must be based on a ruling of the Internal Revenue Service issued, or a change in U.S. federal income tax law occurring, after the date of the indenture, since such a result would not occur under the U.S. federal income tax laws in effect on that date.

Although we may discharge or decrease our obligations under the indenture as described in the two preceding paragraphs, we may not avoid, among other things, our duty to register the transfer or exchange of any series of debt securities, to replace any temporary, mutilated, destroyed, lost or stolen series of debt securities or to maintain an office or agency in respect of any series of debt securities.

9

Modification of the Indenture

The indenture provides that we and the trustee may enter into supplemental indentures without the consent of the holders of debt securities to, among other things:

• evidence the assumption by a successor entity of our obligations;

• add to our covenants for the benefit of the holders of debt securities, or to surrender any rights or power conferred upon us;

• add any additional events of default;

• add to, change or eliminate any of the provisions of the indenture in a manner that will become effective only when there is no outstanding debt security which is entitled to the benefit of the provision as to which the modification would apply;

• add guarantees with respect to or secure any debt securities;

• establish the forms or terms of debt securities of any series;

• evidence and provide for the acceptance of appointment by a successor trustee and add to or change any of the provisions of the indenture as is necessary for the administration of the trusts by more than one trustee;

• cure any ambiguity or correct any inconsistency or defect in the indenture;

• modify, eliminate or add to the provisions of the indenture as shall be necessary to effect the qualification of the indenture under the Trust Indenture Act of 1939 or under any similar federal statute later enacted, and to add to the indenture such other provisions as may be expressly required by the Trust Indenture Act; and

• make any other provisions with respect to matters or questions arising under the indenture that will not be inconsistent with any provision of the indenture as long as the new provisions do not adversely affect the interests of the holders of any outstanding debt securities of any series created prior to the modification.

The indenture also provides that we and the trustee may, with the consent of the holders of not less than a majority in aggregate principal amount of debt securities of each series of debt securities affected by such supplemental indenture then outstanding, add any provisions to, or change in any manner, eliminate or modify in any way the provisions of, the indenture or any supplemental indenture or modify in any manner the rights of the holders of the debt securities. We and the trustee may not, however, without the consent of the holder of each outstanding debt security affected thereby:

• extend the final maturity of any debt security;

• reduce the principal amount or premium, if any;

• reduce the rate or extend the time of payment of interest;

• reduce the amount of the principal of any debt security issued with an original issue discount that is payable upon acceleration;

• change the currency in which the principal, and any premium or interest, is payable;

• impair the right to institute suit for the enforcement of any payment on any debt security when due;

• if applicable, adversely affect the right of a holder to convert or exchange a debt security; or

• reduce the percentage of holders of debt securities of any series whose consent is required for any modification of the indenture or for waivers of compliance with or defaults under the indenture with respect to debt securities of that series.

10

The indenture provides that the holders of not less than a majority in aggregate principal amount of the then outstanding debt securities of any series, by notice to the relevant trustee, may on behalf of the holders of the debt securities of that series waive any default and its consequences under the indenture except:

• a default in the payment of, any premium and any interest on, or principal of, any such debt security held by a nonconsenting holder; or

• a default in respect of a covenant or provision of the indenture that cannot be modified or amended without the consent of the holder of each outstanding debt security of each series affected.

Concerning the Trustee

The indenture provides that there may be more than one trustee under the indenture, each for one or more series of debt securities. If there are different trustees for different series of debt securities, each trustee will be a trustee of a trust under the indenture separate and apart from the trust administered by any other trustee under that indenture. Except as otherwise indicated in this prospectus or any prospectus supplement, any action permitted to be taken by a trustee may be taken by such trustee only on the one or more series of debt securities for which it is the trustee under the indenture. Any trustee under the indenture may resign or be removed from one or more series of debt securities. All payments of principal of, and any premium and interest on, and all registration, transfer, exchange, authentication and delivery of, the debt securities of a series will be effected by the trustee for that series at an office designated by the trustee in New York, New York.

The indenture provides that, except during the continuance of an event of default, the trustee will perform only such duties as are specifically set forth in the indenture. During the existence of an event of default, the trustee will exercise those rights and powers vested in it under the indenture and use the same degree of care and skill in its exercise as a prudent person would exercise under the circumstances in the conduct of such person’s own affairs.

If the trustee becomes a creditor of ours, the indenture places limitations on the right of the trustee to obtain payment of claims or to realize on property received in respect of any such claim as security or otherwise. The trustee may engage in other transactions. If it acquires any conflicting interest relating to any duties concerning the debt securities, however, it must eliminate the conflict or resign as trustee.

No Individual Liability of Incorporators, Stockholders, Officers or Directors

The indenture provides that no past, present or future director, officer, stockholder or employee of ours, any of our affiliates, or any successor corporation, in their capacity as such, shall have any individual liability for any of our obligations, covenants or agreements under the debt securities or the indenture.

Governing Law

The indenture and the debt securities will be governed by, and construed in accordance with, the laws of the State of New York.

DESCRIPTION OF CAPITAL STOCK

This section describes the general terms and provisions of the shares of our common stock, $0.0001 par value per share, and preferred stock, $0.0001 par value per share. This description is only a summary. Our restated certificate of incorporation, or our Certificate of Incorporation, and our amended and restated bylaws, or our Bylaws, have been filed as exhibits to our periodic reports filed with the SEC, which are incorporated by reference in this prospectus. You should read our Certificate of Incorporation and our Bylaws for additional information before you buy any of our common stock, preferred stock or other securities. See “Where You Can Find More Information.”

Authorized and Outstanding Stock

Our Certificate of Incorporation authorizes the issuance of 600,000,000 shares of common stock, $0.0001 par value per share, and 150,000,000 shares of undesignated preferred stock, $0.0001 par value per share. As of December 31, 2021, there were 413,340,550 shares of common stock and no shares of preferred stock outstanding. The outstanding shares of common stock are duly authorized, validly issued, fully paid and non-assessable. As of December 31, 2021, there were 91 holders of record of our common stock. Because many of our shares of common stock are held by brokers and other nominees on behalf of stockholders, this number is not indicative of the total number of stockholders represented by these stockholders of record.

Common Stock

Voting Power

Except as otherwise required by law or as otherwise provided in any certificate of designation for any series of preferred stock, the holders of common stock possess all voting power for the election of our directors and all other matters requiring stockholder action. Holders of common stock are entitled to one vote per share on matters to be voted on by stockholders.

Dividends

Holders of outstanding shares of our common stock will be entitled to receive such dividends, if any, as may be declared from time to time by our board of directors in its discretion out of funds legally available therefor. In no event will any stock dividends or stock splits or combinations of stock be declared or made on common stock unless the shares of common stock at the time outstanding are treated equally and identically. We have not paid any cash dividends to date. We may retain future earnings, if any, for future operations, expansion and debt repayment and have no current plans to pay cash dividends for the foreseeable future. Any decision to declare and pay dividends in the future will be made at the discretion of the board and will depend on, among other things, our results of operations, financial condition, cash requirements, contractual restrictions and other factors that the board may deem relevant. In addition, our ability to pay dividends may be limited by covenants of future outstanding indebtedness we or our subsidiaries incur.

Liquidation, Dissolution and Winding Up

In the event of our voluntary or involuntary liquidation, dissolution, distribution of assets or winding-up, the holders of the common stock will be entitled to receive an equal amount per share of all of our assets of whatever kind available for distribution to stockholders, after the rights of the holders of the preferred stock have been satisfied.

Preemptive or Other Rights

Holders of our common stock have no preemptive, conversion or other subscription rights, and there are no sinking fund or redemption provisions applicable to our common stock.

12

Election of Directors

Our board of directors is divided into three classes, each of which will generally serve for a term of three years with only one class of directors being elected in each year. There is no cumulative voting with respect to the election of directors, with the result that the holders of more than 50% of the shares voted for the election of directors can elect all of the directors.

Registration Rights

On June 3, 2020, we entered into a Registration Rights and Lock-Up Agreement with certain of our stockholders, or the Holders. Pursuant to the terms of the Registration Rights and Lock-Up Agreement, subject to certain requirements and customary conditions, including with regard to the number of demand rights that may be exercised, the Holders may demand at any time or from time to time, that the Company file a registration statement on Form S-3 (or on Form S-1 if Form S-3 is not available) to register the Company’s securities held by such Holders. The Registration Rights and Lock-Up Agreement will also provide the Holders with “piggy-back” registration rights, subject to certain requirements and customary conditions.

On June 11, 2021 and September 24, 2021, we entered into common stock purchase agreements with Tumim Stone Capital LLC, or Tumim, pursuant to which Tumim committed to purchase up to an aggregate of $600 million of our common stock. In connection with such purchase agreements, we also entered into registration rights agreements with Tumim to register for resale under the Securities Act the shares of our common stock that have been and may be issued to Tumim under the purchase agreements.

We generally must pay all expenses relating to any such registration, other than underwriting discounts and selling commissions. The terms of the registration rights are specified in the relevant registration rights agreement.

Preferred Stock

Our Certificate of Incorporation provides that shares of preferred stock may be issued from time to time in one or more series. Our board of directors is authorized to fix the voting rights, if any, designations, powers and preferences, the relative, participating, optional or other special rights, and any qualifications, limitations and restrictions thereof, applicable to the shares of each series of preferred stock. Our board of directors is able to, without stockholder approval, issue preferred stock with voting and other rights that could adversely affect the voting power and other rights of the holders of the common stock and could have anti-takeover effects. The ability of our board of directors to issue preferred stock without stockholder approval could have the effect of delaying, deferring or preventing a change of control of Nikola or the removal of existing management.

Certain Provisions of Delaware Law and Our Certificate of Incorporation and Bylaws

Certain provisions of Delaware law, our Certificate of Incorporation and our Bylaws, described below, may have the effect of delaying, deferring or discouraging another party from acquiring control of us.

Special Meetings of Stockholders

Our Certificate of Incorporation provides that special meetings of our stockholders may be called by such persons as provided in our Bylaws. Our Bylaws provide that special meetings of our stockholders may be called only by (i) a majority vote of our board of directors, (ii) our Secretary, at the request of the Chairman of our board, (iii) our executive chairman, or (iv) the vote of the stockholders owning not less than 25% of our issued and outstanding stock; provided that our board of directors approves such stockholder request for a special meeting.

13

Advance Notice Requirements for Stockholder Proposals and Director Nominations

Our Bylaws provide that stockholders seeking to bring business before our annual meeting of stockholders, or to nominate candidates for election as directors at our annual meeting of stockholders, must provide timely notice of their intent in writing. To be timely under our Bylaws, a stockholder’s notice will need to be received by the company secretary at our principal executive offices not later than the close of business on the 90th day nor earlier than the open of business on the 120th day prior the anniversary of the date of our proxy statement provided in connection with the previous year’s annual meeting of stockholders; provided, however, that in the event that no annual meeting was held in the previous year or the annual meeting is called for a date that is more than 30 days before or after the anniversary date of the previous year’s annual meeting, notice by the stockholder must be received by the secretary no later than the close of business on the latter of the 90th day prior to such annual meeting and the 10th day following the day on which public announcement of the date of such meeting is first made. Our Certificate of Incorporation and our Bylaws specify certain requirements as to the form and content of a stockholders’ meeting. These provisions may preclude our stockholders from bringing matters before our annual meeting of stockholders or from making nominations for directors at our annual meeting of stockholders.

Authorized but Unissued Shares

Our authorized but unissued common stock and preferred stock are available for future issuances without stockholder approval and could be utilized for a variety of corporate purposes, including future offerings to raise additional capital, acquisitions and employee benefit plans. The existence of authorized but unissued and unreserved common stock and preferred stock could render more difficult or discourage an attempt to obtain control of us by means of a proxy contest, tender offer, merger or otherwise.

Exclusive Forum Selection

Our Certificate of Incorporation requires, to the fullest extent permitted by law, that derivative actions brought in our name, actions against directors, officers and employees for breach of fiduciary duty and other similar actions be brought in the Court of Chancery in the State of Delaware or, if that court lacks subject matter jurisdiction, another federal or state court situated in the State of Delaware. Any person or entity purchasing or otherwise acquiring any interest in shares of our capital stock shall be deemed to have notice of and consented to the forum provisions in our Certificate of Incorporation. Our Certificate of Incorporation also requires the federal district courts of the United States shall be the exclusive forum for the resolution of any complaint asserting a cause of action under the Securities Act and the Exchange Act, and the stockholder bringing the suit will be deemed to have to service of process on such stockholder’s counsel. Although we believe these provisions benefit us by providing increased consistency in the application of Delaware law in the types of lawsuits to which it applies, a court may determine that these provisions are unenforceable, and to the extent they are enforceable, the provisions may have the effect of discouraging lawsuits against our directors and officers, although our stockholders will not be deemed to have waived our compliance with federal securities laws and the rules and regulations thereunder.

Section 203 of the Delaware General Corporation Law

We are subject to the provisions of Section 203 of the General Corporation Law of the State of Delaware, or the DGCL, regulating corporate takeovers. In general, Section 203 prohibits a publicly-held Delaware corporation from engaging, under certain circumstances, in a business combination with an interested stockholder for a period of three years following the date that such stockholder became an interested stockholder unless:

• prior to the date of the transaction, the board of directors of the corporation approved either the business combination or the transaction which resulted in the stockholder becoming an interested stockholder;

14

• upon completion of the transaction that resulted in the stockholder becoming an interested stockholder, the interested stockholder owned at least 85% of the voting stock of the corporation outstanding at the time the transaction commenced, excluding for purposes of determining the voting stock outstanding, but not the outstanding voting stock owned by the interested stockholder, (1) shares owned by persons who are directors and also officers and (2) shares owned by employee stock plans in which employee participants do not have the right to determine confidentially whether shares held subject to the plan will be tendered in a tender or exchange offer; or

• at or subsequent to the date of the transaction, the business combination is approved by the board of directors of the corporation and authorized at an annual or special meeting of stockholders, and not by written consent, by the affirmative vote of at least 66 2/3% of the outstanding voting stock which is not owned by the interested stockholder.

Generally, Section 203 defines a “business combination” to include a merger, asset or stock sale, or other transaction resulting in a financial benefit to the “interested stockholder,” and an “interested stockholder” as a person who, together with affiliates and associates, owns or, within three years prior to the determination of interested stockholder status, did own 15% or more of a corporation’s outstanding voting stock. We expect the existence of this provision to have an anti-takeover effect with respect to transactions our board of directors does not approve in advance. We also anticipate that Section 203 may discourage business combinations or other attempts that might result in a premium over the market price for the shares of common stock held by our stockholders. A Delaware corporation may opt out of these provisions either with an express provision in its original certificate of incorporation or in an amendment to its certificate of incorporation or bylaws approved by its stockholders. However, we have not opted out, and do not currently intend to opt out of, these provisions.

Certain of the provisions of the DGCL, our Certificate of Incorporation and our Bylaws could have the effect of discouraging others from attempting hostile takeovers and, as a consequence, they may also inhibit temporary fluctuations in the market price of our common stock that often result from actual or rumored hostile takeover attempts. These provisions may also have the effect of preventing changes in our management. It is possible that these provisions could make it more difficult to accomplish transactions that stockholders may otherwise deem to be in their best interests.

Limitation on Liability and Indemnification of Directors and Officers

Our Certificate of Incorporation limits our directors’ liability to the fullest extent permitted under the DGCL. The DGCL provides that directors of a corporation will not be personally liable for monetary damages for breach of their fiduciary duties as directors, except for liability:

• for any transaction from which the director derives an improper personal benefit;

• for any act or omission not in good faith or that involves intentional misconduct or a knowing violation of law;

• for any unlawful payment of dividends or redemption of shares; or

• for any breach of a director’s duty of loyalty to the corporation or its stockholders.

Delaware law and our Certificate of Incorporation provide that we will, in certain situations, indemnify our directors and officers and may indemnify other employees and other agents, to the fullest extent permitted by law. Any indemnified person is also entitled, subject to certain limitations, to advancement, direct payment, or reimbursement of reasonable expenses (including attorneys’ fees and disbursements) in advance of the final disposition of the proceeding.

In addition, we have entered into indemnification agreements with our directors and officers. These agreements, among other things, require us to indemnify our directors and officers for certain expenses, including

15

attorneys’ fees, judgments, fines, and settlement amounts incurred by a director or officer in any action or proceeding arising out of their services as one of our directors or officers or any other company or enterprise to which the person provides services at our request.

We maintain a directors’ and officers’ insurance policy pursuant to which our directors and officers are insured against liability for actions taken in their capacities as directors and officers. We believe these provisions in our Certificate of Incorporation and our Bylaws and these indemnification agreements are necessary to attract and retain qualified persons as directors and officers.

Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers, or control persons, in the opinion of the SEC, such indemnification is against public policy as expressed in the Securities Act and is therefore unenforceable.

DESCRIPTION OF DEPOSITARY SHARES

The following description of the depositary shares does not purport to be complete and is subject to and qualified in its entirety by the relevant deposit agreement and the depositary receipts with respect to the depositary shares relating to any particular series of preferred stock. You should read these documents as they, and not this description, will define your rights as a holder of depositary shares. Forms of these documents will be filed with the SEC in connection with the offering of depositary shares.

General

If we elect to offer fractional interests in shares of preferred stock, we will provide for the issuance by a depositary to the public of receipts for depositary shares. Each depositary share will represent fractional interests of preferred stock. We will deposit the shares of preferred stock underlying the depositary shares under a deposit agreement between us and a bank or trust company selected by us. The bank or trust company must have its principal office in the United States and a combined capital and surplus of at least $50 million. The depositary receipts will evidence the depositary shares issued under the deposit agreement.

The deposit agreement will contain terms applicable to the holders of depositary shares in addition to the terms stated in the depositary receipts. Each owner of depositary shares will be entitled to all the rights and preferences of the preferred stock underlying the depositary shares in proportion to the applicable fractional interest in the underlying shares of preferred stock. The depositary will issue the depositary receipts to individuals purchasing the fractional interests in shares of the related preferred stock according to the terms of the offering described in a prospectus supplement.

Dividends and Other Distributions

The depositary will distribute all cash dividends or other cash distributions received for the preferred stock to the entitled record holders of depositary shares in proportion to the number of depositary shares that the holder owns on the relevant record date. The depositary will distribute only an amount that can be distributed without attributing to any holder of depositary shares a fraction of one cent. The depositary will add the undistributed balance to and treat it as part of the next sum received by the depositary for distribution to holders of depositary shares.

If there is a non-cash distribution, the depositary will distribute property received by it to the entitled record holders of depositary shares, in proportion, insofar as possible, to the number of depositary shares owned by the holders, unless the depositary determines, after consultation with us, that it is not feasible to make such distribution. If this occurs, the depositary may, with our approval, sell such property and distribute the net proceeds from the sale to the holders. The deposit agreement also will contain provisions relating to how any subscription or similar rights that we may offer to holders of the preferred stock will be available to the holders of the depositary shares.

Conversion, Exchange, Redemption and Liquidation

If any series of preferred stock underlying the depositary shares may be converted or exchanged, each record holder of depositary receipts will have the right or obligation to convert or exchange the depositary shares represented by the depositary receipts.

The terms on which the depositary shares relating to the preferred stock of any series may be redeemed, and any amounts distributable upon our liquidation, dissolution or winding up, will be described in the relevant prospectus supplement.

17

Voting

When the depositary receives notice of a meeting at which the holders of the preferred stock are entitled to vote, the depositary will mail the particulars of the meeting to the record holders of the depositary shares. Each record holder of depositary shares on the record date may instruct the depositary on how to vote the shares of preferred stock underlying the holder’s depositary shares. The depositary will try, if practical, to vote the number of shares of preferred stock underlying the depositary shares according to the instructions. We will agree to take all reasonable action requested by the depositary to enable it to vote as instructed.

Amendments

We and the depositary may agree to amend the deposit agreement and the depositary receipt evidencing the depositary shares. Any amendment that (a) imposes or increases certain fees, taxes or other charges payable by the holders of the depositary shares as described in the deposit agreement or that (b) otherwise prejudices any substantial existing right of holders of depositary shares, will not take effect until 30 days after the depositary has mailed notice of the amendment to the record holders of depositary shares. Any holder of depositary shares that continues to hold its shares at the end of the 30-day period will be deemed to have agreed to the amendment.

Termination

We may direct the depositary to terminate the deposit agreement by mailing a notice of termination to holders of depositary shares at least 30 days prior to termination. In addition, a deposit agreement will automatically terminate if:

• the depositary has redeemed all related outstanding depositary shares, or

• we have liquidated, terminated or wound up our business and the depositary has distributed the preferred stock of the relevant series to the holders of the related depositary shares.

Payment of Fees and Expenses

We will pay all fees, charges and expenses of the depositary, including the initial deposit of the preferred stock and any redemption of the preferred stock. Holders of depositary shares will pay transfer and other taxes and governmental charges and any other charges as are stated in the deposit agreement for their accounts.

Resignation and Removal of Depositary

At any time, the depositary may resign by delivering notice to us, and we may remove the depositary. Resignations or removals will take effect upon the appointment of a successor depositary and its acceptance of the appointment. The successor depositary must be appointed within 60 days after delivery of the notice of resignation or removal and must be a bank or trust company having its principal office in the United States and having a combined capital and surplus of at least $50 million.

Reports

The depositary will forward to the holders of depositary shares all reports and communications from us that are delivered to the depositary and that we are required by law, the rules of an applicable securities exchange or our Certificate of Incorporation to furnish to the holders of the preferred stock. Neither we nor the depositary will be liable if the depositary is prevented or delayed by law or any circumstances beyond its control in performing its obligations under the deposit agreement. The deposit agreement limits our obligations and the depositary’s obligations to performance in good faith of the duties stated in the deposit agreement. Neither we nor the depositary will be obligated to prosecute or defend any legal proceeding connected with any depositary shares or preferred stock unless the holders of depositary shares requesting us to do so furnish us with satisfactory indemnity. In performing our obligations, we and the depositary may rely upon the written advice of our counsel or accountants, on any information that competent people provide to us and on documents that we believe are genuine.

18

DESCRIPTION OF WARRANTS

Outstanding Private Warrants

As of December 31, 2021, there were 760,915 private warrants to purchase common stock outstanding held by 12 holders of record. Each warrant entitles the registered holder to purchase one share of common stock at a price of $11.50 per share, subject to adjustment as discussed below, at any time commencing on July 3, 2020. The warrants will expire at 5:00 p.m., New York City time, on June 3, 2025, except that any private warrants issued to Cowen Investments II, LLC will expire on May 15, 2023.

The registration statement registering the issuance of the shares of common stock underlying the private warrants, the resale of the private warrants, and the shares common stock that may be issued upon exercise of the private warrants was declared effective by the SEC on July 17, 2020.

The warrants contain customary anti-dilution provisions adjusting the number of shares of common stock issuable upon exercise of the warrants and the exercise price of the warrants in the event of stock splits, stock dividends, stock combinations and reclassifications, certain dividends and distributions on our common stock, and certain reorganizations, mergers and consolidations involving us.

The private warrants are issued under and subject to the terms of the Warrant Agreement between Continental Stock Transfer & Trust Company, as warrant agent, and us.

Warrants Issuable

The following is a summary of the general terms of the warrants we may offer and sell under this prospectus.

We may issue additional warrants for the purchase of debt securities, preferred stock, common stock, depositary shares, or any combination thereof. We may issue warrants independently or together with any other securities offered by any prospectus supplement and may be attached to or separate from the other offered securities. Each series of warrants may be issued under a separate warrant agreement to be entered into by us with a warrant agent. The applicable warrant agent will act solely as our agent in connection with the warrants and will not assume any obligation or relationship of agency or trust for or with any holders or beneficial owners of warrants. Further terms of the warrants and the applicable warrant agreements will be set forth in the applicable prospectus supplement.

The applicable prospectus supplement relating to any particular issue of warrants will describe the terms of the warrants, including, as applicable, the following:

• the title of the warrants;

• the aggregate number of the warrants;

• the price or prices at which the warrants will be issued;

• the designation, terms and number of shares of debt securities, preferred stock or common stock purchasable upon exercise of the warrants;

• the designation and terms of the offered securities, if any, with which the warrants are issued and the number of the warrants issued with each offered security;

• the date, if any, on and after which the warrants and the related debt securities, preferred stock or common stock will be separately transferable;

• the price at which each share of debt securities, preferred stock or common stock purchasable upon exercise of the warrants may be purchased;

19

• the date on which the right to exercise the warrants shall commence and the date on which that right shall expire;

• information with respect to book-entry procedures, if any;

• a discussion of certain federal income tax considerations; and

• any other terms of the warrants, including terms, procedures and limitations relating to the exchange and exercise of the warrants.

We and the applicable warrant agent may amend or supplement the warrant agreement for a series of warrants without the consent of the holders of the warrants issued thereunder to effect changes that are not inconsistent with the provisions of the warrants and that do not materially and adversely affect the interests of the holders of the warrants.

20

DESCRIPTION OF RIGHTS

We may issue rights to purchase common stock or preferred stock. This prospectus and any accompanying prospectus supplement will contain the material terms and conditions for each right. The accompanying prospectus supplement may add, update or change the terms and conditions of the rights as described in this prospectus.

We will describe in the applicable prospectus supplement the terms and conditions of the issue of rights being offered, the rights agreement relating to the rights and the rights certificates representing the rights, including, as applicable:

• the title of the rights;

• the date of determining the stockholders entitled to the rights distribution;

• the title, aggregate number of shares of common stock or preferred stock purchasable upon exercise of the rights;

• the exercise price;

• the aggregate number of rights issued;

• the date, if any, on and after which the rights will be separately transferable;

• the date on which the right to exercise the rights will commence and the date on which the right will expire; and

• any other terms of the rights, including terms, procedures and limitations relating to the distribution, exchange and exercise of the rights.

Each right will entitle the holder of rights to purchase for cash the specific number of shares of common stock or preferred stock at the exercise price provided in the applicable prospectus supplement. Rights may be exercised at any time up to the close of business on the expiration date for the rights provided in the applicable prospectus supplement. After the close of business on the expiration date, all unexercised rights will be void.

Holders may exercise rights as described in the applicable prospectus supplement. Upon receipt of payment and the rights certificate properly completed and duly executed at the corporate trust office of the rights agent or any other office indicated in the prospectus supplement, we will, as soon as practicable, forward the shares of common stock or preferred stock purchasable upon exercise of the rights. If less than all of the rights issued in any rights offering are exercised, we may offer any unsubscribed securities directly to persons other than stockholders, to or through agents, underwriters or dealers or through a combination of such methods, including pursuant to standby underwriting arrangements, as described in the applicable prospectus supplement.

21

FORMS OF SECURITIES

Each debt security, depositary share, warrant and right will be represented either by a certificate issued in definitive form to a particular investor or by one or more global securities representing the entire issuance of securities. Unless the applicable prospectus supplement provides otherwise, certificated securities will be issued in definitive form and global securities will be issued in registered form. Definitive securities name you or your nominee as the owner of the security, and in order to transfer or exchange these securities or to receive payments other than interest or other interim payments, you or your nominee must physically deliver the securities to the trustee, registrar, paying agent or other agent, as applicable. Global securities name a depositary or its nominee as the owner of the debt securities, depositary shares, warrants or rights represented by these global securities. The depositary maintains a computerized system that will reflect each investor’s beneficial ownership of the securities through an account maintained by the investor with its broker/dealer, bank, trust company or other representative, as we explain more fully below.

Registered Global Securities

We may issue the registered debt securities, depositary shares, warrants and rights in the form of one or more fully registered global securities that will be deposited with a depositary or its nominee identified in the applicable prospectus supplement and registered in the name of that depositary or nominee. In those cases, one or more registered global securities will be issued in a denomination or aggregate denominations equal to the portion of the aggregate principal or face amount of the securities to be represented by registered global securities. Unless and until it is exchanged in whole for securities in definitive registered form, a registered global security may not be transferred except as a whole by and among the depositary for the registered global security, the nominees of the depositary or any successors of the depositary or those nominees.

If not described below, any specific terms of the depositary arrangement with respect to any securities to be represented by a registered global security will be described in the prospectus supplement relating to those securities. We anticipate that the following provisions will apply to all depositary arrangements.

Ownership of beneficial interests in a registered global security will be limited to persons, called participants, that have accounts with the depositary or persons that may hold interests through participants. Upon the issuance of a registered global security, the depositary will credit, on its book-entry registration and transfer system, the participants’ accounts with the respective principal or face amounts of the securities beneficially owned by the participants. Any underwriters, dealers or agents participating in the distribution of the securities will designate the accounts to be credited. Ownership of beneficial interests in a registered global security will be shown on, and the transfer of ownership interests will be effected only through, records maintained by the depositary, with respect to interests of participants, and on the records of participants, with respect to interests of persons holding through participants. The laws of some states may require that some purchasers of securities take physical delivery of these securities in definitive form. These laws may impair your ability to own, transfer or pledge beneficial interests in registered global securities.

So long as the depositary, or its nominee, is the registered owner of a registered global security, that depositary or its nominee, as the case may be, will be considered the sole owner or holder of the securities represented by the registered global security for all purposes under the applicable indenture, deposit agreement, warrant agreement or rights agreement. Except as described below, owners of beneficial interests in a registered global security:

• will not be entitled to have the securities represented by the registered global security registered in their names;

• will not receive or be entitled to receive physical delivery of the securities in definitive form; and

• will not be considered the owners or holders of the securities under the applicable indenture, deposit agreement, warrant agreement or rights agreement.

22

Accordingly, each person owning a beneficial interest in a registered global security must rely on the procedures of the depositary for that registered global security and, if that person is not a participant, on the procedures of the participant through which the person owns its interest, to exercise any rights of a holder under the applicable indenture, deposit agreement, warrant agreement or rights agreement.

We understand that under existing industry practices, if we request any action of holders or if an owner of a beneficial interest in a registered global security desires to give or take any action that a holder is entitled to give or take under the applicable indenture, deposit agreement, warrant agreement or rights agreement, the depositary for the registered global security would authorize the participants holding the relevant beneficial interests to give or take that action, and the participants would authorize beneficial owners owning through them to give or take that action or would otherwise act upon the instructions of beneficial owners holding through them.

We will make payments of principal, premium, if any, and interest, if any, on debt securities, and any payments to holders with respect to depositary shares, warrants or rights, represented by a registered global security registered in the name of a depositary or its nominee to the depositary or its nominee, as the case may be, as the registered owner of the registered global security. None of us, the trustees, the depositaries for depositary shares, the warrant agents, the rights agents or any other agent of ours, agent of the trustees, agent of such depositaries, agent of the warrant agents or agent of the rights agents will have any responsibility or liability for any aspect of the records relating to, or payments made on account of, beneficial ownership interests in the registered global security or for maintaining, supervising or reviewing any records relating to those beneficial ownership interests.

We expect that the depositary for any of the securities represented by a registered global security, upon receipt of any payment of principal, premium, interest or other distribution of underlying securities or other property to holders on that registered global security, will immediately credit participants’ accounts in amounts proportionate to their respective beneficial interests in that registered global security as shown on the records of the depositary. We also expect that standing customer instructions and customary practices will govern payments by participants to owners of beneficial interests in a registered global security held through the participants, as is now the case with the securities held for the accounts of customers registered in “street name.” We also expect that any of these payments will be the responsibility of those participants.

If the depositary for any of the securities represented by a registered global security is at any time unwilling or unable to continue as depositary or ceases to be a clearing agency registered under the Securities Exchange Act of 1934, or Exchange Act, and a successor depositary registered as a clearing agency under the Exchange Act is not appointed by us within 90 days, we will issue securities in definitive form in exchange for the registered global security that had been held by the depositary. Any securities issued in definitive form in exchange for a registered global security will be registered in the name or names that the depositary gives to the relevant trustee, warrant agent, unit agent or other relevant agent of ours or theirs. It is expected that the depositary’s instructions will be based upon directions received by the depositary from participants with respect to ownership of beneficial interests in the registered global security that had been held by the depositary.

PLAN OF DISTRIBUTION

We may sell the securities offered by this prospectus to one or more underwriters or dealers for public offering and sale by them or to investors directly or through agents, including in underwritten public offerings, at-the-market offerings, negotiated transactions, block trades or a combination of these methods. The accompanying prospectus supplement will set forth the terms of the offering and the method of distribution and will identify any firms acting as underwriters, dealers or agents in connection with the offering, including:

• the name or names of any underwriters, dealers or agents, if any;

• the purchase price of the securities and the proceeds to us from the sale;

• any underwriting discounts and other items constituting compensation to underwriters, dealers or agents;

• any public offering price;

• any discounts or concessions allowed or reallowed or paid to dealers; and

• any securities exchange or market on which the securities offered in the prospectus supplement may be listed.

Only those underwriters identified in such prospectus supplement are deemed to be underwriters in connection with the securities offered in the prospectus supplement.

The distribution of the securities may be effected from time to time in one or more transactions at a fixed price or prices, which may be changed, or at prices determined as the applicable prospectus supplement specifies, including at prevailing market prices, at prices related to such prevailing market prices or at negotiated prices. The securities may be sold through an at the market offering, a rights offering, forward contracts or similar arrangements. In addition, we may enter into derivative transactions with third parties, or sell securities not covered by this prospectus to third parties in privately negotiated transactions. If the applicable prospectus supplement so indicates, in connection with those derivatives, the third parties may sell securities covered by this prospectus and the applicable prospectus supplement, including in short sale transactions. If so, the third party may use securities pledged by us or borrowed from us or others to settle those sales or to close out any related open borrowings of stock, and may use securities received from us in settlement of those derivatives to close out any related open borrowings of stock. The third party in such sale transactions will be an underwriter and, if not identified in this prospectus, will be named in the applicable prospectus supplement (or a post-effective amendment). In addition, we may otherwise loan or pledge securities to a financial institution or other third party that in turn may sell the securities short using this prospectus and an applicable prospectus supplement. Such financial institution or other third party may transfer its economic short position to investors in our securities or in connection with a concurrent offering of other securities.

In connection with the sale of the securities, underwriters, dealers or agents may be deemed to have received compensation from us in the form of underwriting discounts or commissions and also may receive commissions from securities purchasers for whom they may act as agent. Underwriters may sell the securities to or through dealers, and the dealers may receive compensation in the form of discounts, concessions or commissions from the underwriters or commissions from the purchasers for whom they may act as agent.

We will provide in the applicable prospectus supplement information regarding any underwriting discounts or other compensation that we pay to underwriters or agents in connection with the securities offering, and any discounts, concessions or commissions that underwriters allow to dealers. Underwriters, dealers and agents participating in the securities distribution may be deemed to be underwriters, and any discounts, commissions or concessions they receive and any profit they realize on the resale of the securities may be deemed to be underwriting discounts and commissions under the Securities Act of 1933. Underwriters and their controlling persons, dealers and agents may be entitled, under agreements entered into with us, to indemnification against

24

and contribution toward specific civil liabilities, including liabilities under the Securities Act. Some of the underwriters, dealers or agents who participate in the securities distribution may engage in other transactions with, and perform other services for, us or our subsidiaries in the ordinary course of business.

Our common stock is currently listed on the Nasdaq Global Select Market, but any other securities may or may not be listed on a national securities exchange. To facilitate the offering of securities, certain persons participating in the offering may engage in transactions that stabilize, maintain or otherwise affect the price of the securities. This may include over-allotments or short sales of the securities, which involve the sale by persons participating in the offering of more securities than were sold to them. In these circumstances, these persons would cover such over-allotments or short positions by making purchases in the open market or by exercising their over-allotment option, if any. In addition, these persons may stabilize or maintain the price of the securities by bidding for or purchasing securities in the open market or by imposing penalty bids, whereby selling concessions allowed to dealers participating in the offering may be reclaimed if securities sold by them are repurchased in connection with stabilization transactions. The effect of these transactions may be to stabilize or maintain the market price of the securities at a level above that which might otherwise prevail in the open market. These transactions may be discontinued at any time.

LEGAL MATTERS

The validity of any securities offered by this prospectus will be passed upon for us by Pillsbury Winthrop Shaw Pittman LLP.

EXPERTS

The consolidated financial statements of Nikola Corporation incorporated by reference in Nikola Corporation’s Annual Report (Form 10-K) for the year ended December 31, 2021, and the effectiveness of Nikola Corporation’s internal control over financial reporting as of December 31, 2021, have been audited by Ernst & Young LLP, independent registered public accounting firm, as set forth in their reports thereon included therein, and incorporated herein by reference. Such financial statements are, and audited financial statements to be included in subsequently filed documents will be, incorporated herein in reliance upon the reports of Ernst & Young LLP pertaining to such financial statements and the effectiveness of our internal control over financial reporting as of the respective dates (to the extent covered by consents filed with the Securities and Exchange Commission) given on the authority of such firm as experts in accounting and auditing.

CHANGE IN AUDITOR

On June 3, 2020, our board of directors approved the engagement of Ernst & Young LLP, or EY, as our independent registered public accounting firm to audit the company’s consolidated financial statements for the year ending December 31, 2020. EY served as the independent registered public accounting firm of Legacy Nikola prior to the Business Combination. Accordingly, RSM US LLP, or RSM, our independent registered public accounting firm prior to the Business Combination, was informed that it would be replaced by EY as our independent registered public accounting firm following completion of the company’s audit for the year ended December 31, 2019, which consists only of the accounts of the pre-business combination special purpose acquisition company.

RSM’s report on the company’s balance sheets as of December 31, 2019 and 2018, the related statements of operations, stockholders’ equity and cash flows for the year ended December 31, 2019 and for the period from January 23, 2018 (inception) to December 31, 2018, and the related notes to the financial statements, or collectively, the financial statements, did not contain any adverse opinion or disclaimer of opinion, nor were they qualified or modified as to uncertainty, audit scope or accounting principles.

During the period from January 23, 2018 (inception) to December 31, 2019 and the subsequent period through March 31, 2020, there were no: (i) disagreements with RSM on any matter of accounting principles or practices, financial statement disclosures or audited scope or procedures, which disagreements if not resolved to RSM’s satisfaction would have caused RSM to make reference to the subject matter of the disagreement in connection with its report or (ii) reportable events as defined in Item 304(a)(1)(v) of Regulation S-K.

During the period from January 23, 2018 (inception) to December 31, 2018 and the interim period through March 31, 2020, we did not consult EY with respect to either (i) the application of accounting principles to a specified transaction, either completed or proposed; or the type of audit opinion that might be rendered our financial statements, and no written report or oral advice was provided to us by EY that EY concluded was an important factor considered by us in reaching a decision as to the accounting, auditing or financial reporting issue; or (ii) any matter that was either the subject of a disagreement, as that term is described in

Item 304(a)(1)(iv) of Regulation S-K under the Exchange Act and the related instructions to Item 304 of Regulation S-K under the Exchange Act, or a reportable event, as that term is defined in Item 304(a)(1)(v) of Regulation S-K under the Exchange Act.

26

We have provided RSM with a copy of the disclosures made by us in response to Item 304(a) of Regulation S-K under the Exchange Act, and have requested that RSM furnish us with a letter addressed to the SEC stating whether it agrees with the statements made by the registrant in response to this Item 304(a) of Regulation S-K under the Exchange Act and, if not, stating the respects in which it does not agree. A letter from RSM is filed as Exhibit 16.1 to the registration statement of which this prospectus forms a part.
