SUMMARY

This summary highlights the more detailed information contained or incorporated by reference in this prospectus supplement and the accompanying prospectus. Because this is only a summary, it does not contain all of the information that you should consider before deciding whether to invest in our Common Stock. For a more complete understanding of this offering, you should read this entire prospectus supplement and accompanying prospectus carefully, including the documents incorporated by reference herein, before making an investment decision.

Company Overview

Headquartered in Phoenix, Arizona, we are a market leader in the North America specialty rental services industry. We provide innovative turnkey modular space and portable storage solutions to diverse end markets utilizing a network of approximately 275 branch locations and additional drop lots throughout the United States, Canada, Mexico, and the United Kingdom.

With roots dating back more than 60 years, we lease modular space and portable storage units to customers in the commercial and industrial, construction, education, energy and natural resources, government, and other end markets. We offer our customers an extensive section of “Ready to Work” solutions. In addition to our Ready to Work solutions, we offer value-added products and services, such as the rental of steps, ramps, and furniture packages, damage waivers, and other amenities to improve the overall customer experience. These turnkey solutions offer customers flexible, low-cost, and timely solutions to meet their space needs on an outsourced basis.

On July 1, 2020, WillScot Corporation (“WillScot”) combined with Mobile Mini, Inc. (“Mobile Mini”) in a stock-for-stock merger with WillScot as the surviving company (the “Merger”) and WillScot changed its name to WillScot Mobile Mini Holdings Corp. (“WillScot Mobile Mini”). WillScot Mobile Mini is the holding company for the Williams Scotsman and Mobile Mini family of companies. Immediately following the Merger, WillScot Mobile Mini filed an amended and restated certificate of incorporation, which reclassified all outstanding shares of WillScot Class A common stock and converted such shares into shares of common stock, par value $0.0001 per share, of WillScot Mobile Mini. The WillScot Class A common stock was listed on Nasdaq up until the Merger, and the WillScot Mobile Mini Common Stock has been listed on Nasdaq since the Merger.

As a result of the Merger, the Company operates in four reportable segments as follows: North America Modular Solutions, North America Storage Solutions, United Kingdom Storage Solutions, and Tank and Pump Solutions. The North America Modular Solutions segment (comprised of WillScot’s two reportable segments prior to the Merger, US Modular and Other North America Modular) aligns with the WillScot legacy business prior to the Merger, and the North America Storage Solutions, United Kingdom Storage Solutions, and Tank and Pump Solutions segments align with the Mobile Mini segments prior to the Merger.

Our principal executive offices are located at 4646 E Van Buren Street, Suite 400, Phoenix, Arizona 85008 and our phone number is (480) 894-6311. Our website address is www.willscotmobilemini.com.

RISK FACTORS

Investing in our Common Stock involves risks. Before you make a decision to invest in our Common Stock, in addition to the risks and uncertainties discussed above under “Cautionary Note Regarding Forward-Looking Statements,” you should carefully consider the specific risks set forth herein, in the accompanying prospectus and in the documents incorporated by reference herein and therein, including our Annual Report on Form 10-K/A for the year ended December 31, 2020. If any of these risks actually occur, it may materially harm our business, financial condition, liquidity and results of operations. As a result, the market price of our Common Stock could decline, and you could lose all or part of your investment. Additionally, the risks and uncertainties described in this prospectus supplement, the accompanying prospectus or in any document incorporated by reference herein or therein are not the only risks and uncertainties that we face. Additional risks and uncertainties not presently known to us or that we currently believe to be immaterial may become material and adversely affect our business.

Risks Related to the Offering

Because a majority of the outstanding shares of our Common Stock are or will be, and the Shares of our Common Stock sold in this offering will be, freely tradable without restriction or further registration under the Securities Act, sales of a substantial number of shares of our Common Stock in the public market in and following this offering could cause the market price of our Common Stock to decline.

Sales of a substantial number of shares of our Common Stock in the public market in and following this offering could cause the market price of our Common Stock to decline. All of the Shares of Common Stock to be sold in this offering will be freely tradable without restriction or further registration under the Securities Act. As a result, the lack of a robust resale market may require a stockholder who desires to sell a large number of shares to sell such shares in increments over time to mitigate any adverse impact of the sales on the market price of our Common Stock

You may experience future dilution as a result of future equity offerings.

In order to raise additional capital, we may in the future offer additional shares of our Common Stock or other securities convertible into or exchangeable for our Common Stock at prices that may not be the same as the price per share in this offering. We may sell shares or other securities in any other offering at a price per share that is less than the price per share paid by investors in this offering, and investors purchasing shares or other securities in the future could have rights superior to those of existing stockholders. The price per share at which we sell additional shares of our Common Stock, or securities convertible or exchangeable into Common Stock, in future transactions may be higher or lower than the price per share paid by investors in this offering. Sales of substantial numbers of such shares in the public market could adversely affect the market price of such shares.

The historical market price of our Common Stock has been volatile and the market price of our Common Stock may continue to be volatile and the value of your investment may decline.

Risks Related to our Business

Our largest stockholder may have the ability to influence our business and matters requiring approval by our stockholders.

Sapphire Holding S.à.r.l. (“Sapphire Holding”), which is controlled by TDR Capital, beneficially owns approximately 19.0% of the issued and outstanding shares of our Common Stock. Pursuant to a shareholders agreement (the “Shareholders Agreement”) entered into on July 1, 2020, by and among us and TDR Capital and certain of its affiliates, including Sapphire Holding, TDR Capital has the right to nominate two directors to our Board of Directors, for so long as TDR Capital beneficially owns at least 15% of our Common Stock and one director for so long as TDR Capital beneficially owns at least 5% of our Common Stock. Two directors nominated by TDR Capital currently serve on our Board of Directors. TDR Capital may have the ability to influence matters requiring approval by our stockholders, including the election and removal of directors, amendments to our certificate of incorporation and bylaws, any proposed merger, consolidation or sale of all or substantially all of our assets and certain other corporate transactions. TDR Capital may have interests that are different from those of other stockholders. After the completion of this offering and the Stock Repurchase, TDR Capital will beneficially own approximately 11.4% of the issued and outstanding shares of our Common Stock. Pursuant to the terms of the Shareholders Agreement, as a result of TDR Capital’s reduced ownership of our Common Stock, one of the directors nominated by TDR Capital will resign from our Board of Directors following consummation of this offering.

In August 2018, Sapphire Holding pledged all of the shares of WillScot’s Class A Common Stock that it owned as security for a margin loan under which Sapphire Holding borrowed $125.0 million (the “Margin Loan”). The Margin Loan was scheduled to mature on August 23, 2020. On August 21, 2020, Sapphire Holding entered into an amended and restated margin loan agreement which, among other things, extends the maturity date of the Margin Loan to August 29, 2022. As of June 21, 2021, 42,263,208 shares of Common Stock are pledged to secure repayment of amounts outstanding under the Margin Loan. An event of default under the Margin Loan could result in a foreclosure on the pledged securities and the sale by the lender of the pledged securities in the open market, which could cause the market price of our Common Stock to decline. Such an event could also result in another stockholder beneficially owning a significant amount of our Common Stock. There can be no assurance that Sapphire Holding will be able to extend, repay or refinance the loan on terms acceptable to it or at all.

SELLING STOCKHOLDER

The following table and accompanying footnotes set forth, as of June 21, 2021, the following information regarding the selling stockholder:

•

the number of Shares to be offered by the selling stockholder in this offering; and

•

the number and percentage of total outstanding shares of our Common Stock to be beneficially owned by the selling stockholder after completion of this offering.

The amounts and percentages of our Common Stock beneficially owned are reported on the basis of regulations of the Commission governing the determination of beneficial ownership of securities. Under the rules of the Commission, a person is deemed to be a “beneficial owner” of a security if that person has or shares “voting power,” which includes the power to vote or to direct the voting of such security, or “investment power,” which includes the power to dispose of or to direct the disposition of such security. A person is also deemed to be a beneficial owner of any securities of which that person has a right to acquire beneficial ownership within 60 days. Under these rules, more than one person may be deemed to be a beneficial owner of such securities as to which such person has an economic interest.

The selling stockholder shown in the table below has furnished information with respect to beneficial ownership. We believe, based on the information furnished to us, that the selling stockholder has sole voting and investment power with respect to all shares of Common Stock that it beneficially owns. Unless otherwise described below, to our knowledge, the selling stockholder has not held any position or office or had any other material relationship with us or our affiliates during the three years prior to the date of this prospectus supplement. In addition, except as otherwise described below, based on the information provided to us by the selling stockholder, the selling stockholder is not a broker-dealer or an affiliate of a broker-dealer.

Percentage ownership prior to the offering is based on 230,621,514 shares of our Common Stock outstanding as of June 21, 2021 (which does not treat as outstanding any shares of Common Stock issuable upon exercise of any of our outstanding warrants).

Relationships with Selling Stockholder

Without giving effect to this offering or to the Stock Repurchase, as of June 21, 2021, Sapphire Holding, which is controlled by TDR Capital, beneficially owned approximately 19.0% of the issued and outstanding shares of our Common Stock. Pursuant to the Shareholders Agreement, TDR Capital has the

right to nominate two directors to our Board of Directors, for so long as TDR Capital beneficially owns at least 15% of our Common Stock and one director for so long as TDR Capital beneficially owns at least 5% of our Common Stock. Two directors nominated by TDR Capital currently serve on our Board of Directors. After the completion of this offering and the Stock Repurchase, TDR Capital will beneficially own approximately 11.4% of the issued and outstanding shares of our Common Stock. Pursuant to the terms of the Shareholders Agreement, as a result of TDR Capital’s reduced ownership of our Common Stock, one of the directors nominated by TDR Capital will resign from our Board of Directors following consummation of this offering.

In August 2018, the selling stockholder pledged all of the shares of WillScot’s Class A Common Stock that it owned as security for a margin loan under which the selling stockholder borrowed $125.0 million. The Margin Loan was scheduled to mature on August 23, 2020. On August 21, 2020, the selling stockholder entered into an amended and restated margin loan agreement which, among other things, extends the maturity date of the Margin Loan to August 29, 2022. As of June 21, 2021, 42,263,208 shares of Common Stock are pledged to secure repayment of amounts outstanding under the Margin Loan.

UNDERWRITING

The selling stockholder is offering the Shares described in this prospectus supplement through the underwriter named below. We have entered into an underwriting agreement with the underwriter and the selling stockholder. Subject to the terms and conditions of the underwriting agreement, the selling stockholder has, agreed to sell to the underwriter, and the underwriter has agreed to purchase, at the public offering price less the underwriting discounts and commissions set forth on the cover page of this prospectus supplement, the number of Shares listed next to its name in the following table:

Name	Number of Shares
Morgan Stanley & Co. LLC		14,000,000
Total		14,000,000

The underwriter is committed to purchase all the Shares offered by the selling stockholder if they purchase any such Shares. The underwriting agreement also provides that if an underwriter defaults, the purchase commitments of non-defaulting underwriter may also be increased or this offering may be terminated.

The underwriting fee is equal to the public offering price per Share less the amount paid by the underwriter to the selling stockholder per Share. The underwriting fee is $0.20 per Share. The following table shows the per Share and total underwriting discounts and commissions to be paid to the underwriter by the selling stockholder. No underwriting discounts or commissions will be paid in respect of the Shares purchased by us.

	Per Share			Total
Public offering price		$	27.95		$	391,300,000
Underwriting discounts and commissions		$	0.20		$	2,800,000
Proceeds, before expenses, to the selling stockholder		$	27.75		$	388,500,000

The underwriter proposes to offer the Shares directly to the public at the public offering price set forth on the cover page of this prospectus supplement and to certain dealers at that price less a concession not in excess of $0.12 per Share under the public offering price. After the public offering of the Shares, the offering price and other selling terms may be changed by the underwriter.

The underwriter has an option to purchase up to 2,100,000 additional shares of Common Stock from the selling stockholder to cover sales of shares by the underwriter which exceed the number of shares specified in the table above. The underwriter has 30 days from the date of this prospectus supplement to exercise this option to purchase additional shares. If any additional shares of Common Stock are purchased, the underwriter will offer the additional shares on the same terms as those on which the Shares are being offered.

Subject to certain conditions, we have agreed to repurchase directly from the selling stockholder 3,900,000 shares of our Common Stock held by the selling stockholder as part of our existing stock repurchase program. The price per share to be paid by us in the Stock Repurchase will equal the price at which the underwriter will purchase the Shares from the selling stockholder in this offering. The completion of the Stock Repurchase is expected to occur concurrently with the closing of this offering. This offering is not conditioned upon the completion of the Stock Repurchase.

We estimate that the total expenses of this offering, including registration, filing and listing fees, printing fees and legal and accounting expenses, but excluding the underwriting discounts and commissions, will be approximately $500,000. We will pay all registration expenses in connection with this offering, and the selling stockholder will pay the underwriting discounts, selling commissions and stock transfer taxes of this offering. We have agreed to reimburse the underwriter for certain of their expenses relating to this offering in an amount up to $15,000.

A prospectus in electronic format may be made available on the websites maintained by one or more underwriter, or selling group members, if any, participating in this offering.

Stabilization

In connection with this offering, the underwriter may engage in stabilizing transactions, which involve making bids for, purchasing and selling shares of Common Stock in the open market for the purpose of preventing or retarding a decline in the market price of the Common Stock while this offering is in progress. These stabilizing transactions may include making “naked” short sales of the Common Stock, which involves the sale by the underwriter of a greater number of shares of Common Stock than they are required to purchase in this offering, and purchasing shares of Common Stock on the open market to cover positions created by such short sales. A naked short position may be created if the underwriter is concerned that there may be downward pressure on the price of the Common Stock in the open market that could adversely affect investors who purchase in this offering. To the extent that the underwriter creates a naked short position, they will purchase shares in the open market to cover the position.

The underwriter has advised us that, pursuant to Regulation M under the Securities Act, they may also engage in other activities that stabilize, maintain or otherwise affect the price of the Common Stock, including the imposition of penalty bids or purchases of our Common Stock in the open market.

These activities may have the effect of raising or maintaining the market price of the Common Stock or preventing or retarding a decline in the market price of the Common Stock, and, as a result, the price of the Common Stock may be higher than the price that otherwise might exist in the open market. If the underwriter commences these activities, they may discontinue them at any time. The underwriter may carry out these transactions on Nasdaq, in the over-the-counter market or otherwise.

Certain Relationships

Certain of the underwriter and its affiliates has provided in the past to us and our affiliates and may provide from time to time in the future certain commercial banking, financial advisory, investment banking and other services for us and such affiliates in the ordinary course of their business, for which they have received and may continue to receive customary fees and commissions.

In addition, from time to time, certain of the underwriter and its respective affiliates may purchase, sell or hold a broad array of investments and actively traded securities, derivatives, loans, commodities, currencies, credit default swaps and other financial instruments for their own account or the account of customers, and hold on behalf of themselves or their customers, and such investment and trading activities may involve or relate to our assets, securities and/or instruments (directly, as collateral securing other obligations or otherwise) and/or persons and entities with relationships with us, and may do so in the future. The underwriter and its respective affiliates may also communicate independent investment recommendations, market color

TABLE OF CONTENTS

U.S. FEDERAL INCOME TAX CONSIDERATIONS FOR NON-U.S. HOLDERS

The following is a summary of U.S. federal income tax considerations generally applicable to the ownership and disposition of our Common Stock by a Non-U.S. Holder (as defined below) that holds our Common Stock as a capital asset (generally, property held for investment). This discussion is based on the U.S. Internal Revenue Code of 1986, as amended (the “Code”), U.S. Treasury regulations promulgated thereunder (“Regulations”), judicial decisions, administrative pronouncements, and other relevant applicable authorities, all as in effect as of the date hereof and all of which are subject to change or differing interpretations (possibly with retroactive effect).

This discussion does not address all U.S. federal income tax considerations that may be applicable to Non-U.S. Holders in light of their particular circumstances or Non-U.S. Holders subject to special treatment under U.S. federal income tax law, such as:

•

banks, insurance companies and other financial institutions;

•

dealers or traders in securities;

•

certain former citizens or residents of the United States;

•

persons that elect to mark their securities to market;

•

persons holding our Common Stock as part of a straddle, conversion, or other integrated transaction;

•

persons who acquired shares of our Common Stock as compensation or otherwise in connection with the performance of services;

•

controlled foreign corporations;

•

passive foreign investment companies; and

•

tax-exempt organizations.

In addition, this discussion does not address any U.S. state or local or non-U.S. tax considerations or any U.S. federal estate, gift, alternative minimum tax, or Medicare contribution tax considerations. Non-U.S. Holders should consult their tax advisors regarding the tax considerations to them of owning and disposing of our Common Stock in light of their particular circumstances.

For purposes of this discussion, a “Non-U.S. Holder” is a beneficial owner of our Common Stock (other than an owner treated as a partnership for U.S. federal income tax purposes) and that, for U.S. federal income tax purposes, is not:

•

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

•

a corporation (or other entity treated as a corporation) created or organized in or under the laws of the United States or any political subdivision thereof;

•

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

•

a trust if (i) a U.S. court is able to exercise primary supervision over its administration and one or more U.S. Persons have the authority to control all of its substantial decisions or (ii) it has a valid election in effect under applicable Regulations to be treated as a U.S. person.

If a partnership (or other entity or arrangement treated as a partnership for U.S. federal income tax purposes) holds our Common Stock, the tax treatment of a partner will generally depend on the status of the partner and the activities of the entity. Partners in a partnership should consult their tax advisors regarding the tax considerations of an investment in our Common Stock.

Distributions on Our Common Stock

If we make a distribution of cash or other property (other than certain distributions of our stock) in respect of our Common Stock, the distribution will generally be treated as a dividend for U.S. federal income tax purposes to the extent of our current or accumulated earnings and profits, as determined under U.S. federal income tax principles. Any portion of the distribution that exceeds our current and accumulated

S-23

TABLE OF CONTENTS

earnings and profits will generally be treated first as a return of capital to the extent of the Non-U.S. holder’s adjusted tax basis in our Common Stock and then as gain from the disposition of our Common Stock, the tax treatment of which is discussed below under “— Sale, Exchange, or Other Disposition of Our Common Stock.”

The gross amount of dividends paid to a Non-U.S. Holder with respect to our Common Stock will generally be subject to withholding tax at a rate of 30% unless (i) the Non-U.S. Holder timely provides a duly completed and executed U.S. Internal Revenue Service (“IRS”) Form W-8BEN or W-8BEN-E certifying as to its eligibility for a lower rate of withholding under an applicable income tax treaty or (ii) the Non-U.S. Holder timely provides a duly completed and executed IRS Form W-8ECI certifying that the dividends are effectively connected with its conduct of a trade or business in the United States (and, if required by an applicable income tax treaty, are attributable to a permanent establishment maintained by the Non-U.S. Holder in the United States). In the latter case, the Non-U.S. Holder will generally be subject to U.S. federal income tax with respect to such dividends on a net income basis in the same manner as if the Non-U.S. Holder were a United States person (as defined under the Code). A corporate Non-U.S. holder may also be subject to a “branch profits tax” at a rate of 30% (or such lower rate as may be specified by an applicable income tax treaty) on its effectively connected earnings and profits for the taxable year, as adjusted for certain items. A Non-U.S. Holder eligible for a reduced rate of U.S. federal withholding tax pursuant to an applicable income tax treaty may obtain a refund of any excess amounts withheld by timely filing an appropriate claim for refund with the IRS.

Sale, Exchange, or Other Disposition of Our Common Stock

A Non-U.S. Holder will generally not be subject to U.S. federal income tax on gain realized on a sale, exchange, or other disposition of our Common Stock unless:

•

such gain is effectively connected with a trade or business conducted by the Non-U.S. Holder in the United States (and, if required by an applicable income tax treaty, is attributable to a permanent establishment maintained by the Non-U.S. Holder in the United States), in which case, the Non-U.S. Holder will generally be subject to U.S. federal income tax on the gain on a net income basis as if the Non-U.S. Holder were a United States person (as defined under the Code) and, in the case of a corporate Non-U.S. Holder, may also be subject to a “branch profits tax” at a rate of 30% (or such lower rate as may be specified by an applicable income tax treaty) on its effectively connected earnings and profits for the taxable year, as adjusted for certain items;

•

the Non-U.S. Holder is an individual present in the United States for 183 days or more in the taxable year of the disposition and certain other conditions are satisfied, in which case the gain will generally be subject to U.S. federal income tax at a rate of 30% (or such lower rate as may be specified by an applicable income tax treaty), which gain may be offset by certain U.S.-source capital losses, provided the Non-United States Holder has timely filed United States federal income tax returns with respect to such losses; or

•

we are or become a United States real property holding corporation (as defined in section 897(c) of the Code, a “USRPHC”), at any time within the shorter of the five-year period preceding the disposition or the Non-U.S. Holder’s holding period, and either (i) our Common Stock is not regularly traded on an established securities market, or (ii) the Non-U.S. Holder has owned or is deemed to have owned, at any time within the shorter of the five-year period preceding the disposition or the Non-U.S. Holder’s holding period, more than 5% of our Common Stock. We believe that we are not a USRPHC for U.S. federal income tax purposes and we do not anticipate becoming a USRPHC. Because the determination of whether we are a USRPHC depends, however, on the fair market value of our USRPIs relative to the fair market value of our non-U.S. real property interests and our other business assets, there can be no assurance that we currently are not a USRPHC or that will not become a USRPHC in the future.

Information Reporting and Backup Withholding

Information reporting and, in certain circumstances, backup withholding will apply to the proceeds of a sale or other disposition of our Common Stock made within the United States or conducted through certain

S-24

TABLE OF CONTENTS

United States-related financial intermediaries, unless the beneficial owner certifies under penalty of perjury that it is a non-U.S. holder (and the payor does not have actual knowledge or reason to know that the beneficial owner is a United States person as defined under the Code), or such owner otherwise establishes an exemption.

FATCA Withholding

Certain rules may require withholding at a rate of 30% on dividends in respect of our Common Stock held by or through certain foreign financial institutions (including investment funds), unless such institution (i) enters into, and complies with, an agreement with the Treasury to report, on an annual basis, information with respect to interests in, and accounts maintained by, the institution to the extent such interests or accounts are held by certain U.S. persons and by certain non-U.S. entities that are wholly or partially owned by U.S. persons and to withhold on certain payments or (ii) if required under an intergovernmental agreement between the United States and an applicable foreign country, reports such information to its local tax authority, which will exchange such information with the U.S. authorities. An intergovernmental agreement between the United States and an applicable foreign country may modify these requirements. Accordingly, the entity through which our Common Stock is held will affect the determination of whether such withholding is required. Similarly, dividends in respect of our Common Stock held by an investor that is a non-financial non-U.S. entity that does not qualify under certain exemptions will be subject to withholding at a rate of 30%, unless such entity either (i) certifies that such entity does not have any “substantial United States owners” or (ii) provides certain information regarding the entity’s “substantial United States owners,” which we or the applicable withholding agent will in turn provide to the IRS. Non-U.S. Holders should consult their tax advisors regarding the possible implications of this withholding tax on their investment in our Common Stock.

This discussion of U.S. federal income tax considerations is not intended to be, and should not be construed to be, tax advice. Each prospective investor should consult a tax advisor regarding the particular U.S. federal, state, local, and foreign tax considerations applicable to the ownership and disposition of our Common Stock in light of its particular circumstances.

The Company

On July 1, 2020, WillScot Corporation (“WillScot”) combined with Mobile Mini, Inc. (“Mobile Mini”) in a stock-for-stock merger with WillScot as the surviving company (the “Merger”) and WillScot changed its name to WillScot Mobile Mini Holdings Corp. WillScot Mobile Mini is the holding company for the Williams Scotsman and Mobile Mini family of companies. Immediately following the Merger, WillScot Mobile Mini filed an amended and restated certificate of incorporation, which reclassified all outstanding shares of WillScot Class A common stock and converted such shares into shares of common stock, par value $0.0001 per share, of WillScot Mobile Mini. The WillScot Class A common stock was listed on Nasdaq up until the Merger, and the WillScot Mobile Mini Common Stock has been listed on Nasdaq since the Merger.

Our Common Stock is traded on the Nasdaq Capital Market under the symbol “WSC.”

TABLE OF CONTENTS

RISK FACTORS

Investing in our Common Stock involves risks. Before you make a decision to buy shares of our Common Stock, in addition to the risks and uncertainties discussed above under “Cautionary Note Regarding Forward-Looking Statements,” you should carefully consider the specific risks set forth herein, in the accompanying prospectus and in the documents incorporated by reference herein and therein, including our Annual Report on Form 10-K. If any of these risks actually occur, it may materially harm our business, financial condition, liquidity and results of operations. As a result, the market price of our Common Stock could decline, and you could lose all or part of your investment. Additionally, the risks and uncertainties described in this prospectus or in any document incorporated by reference herein or therein are not the only risks and uncertainties that we face. Additional risks and uncertainties not presently known to us or that we currently believe to be immaterial may become material and adversely affect our business.

Risks Relating to our Common Stock

The historical market price of our Common Stock has been volatile and the market price of our Common Stock may continue to be volatile and the value of your investment may decline.

The historical market price of our Common Stock has been volatile and the market price of our Common Stock may continue to be volatile moving forward. Volatility may cause wide fluctuations in the price of our Common Stock on Nasdaq. The market price of our Common Stock may be influenced by many factors, some of which are beyond our control, including those described in this “Risk Factors” section, factors described above under the heading “Cautionary Note Regarding Forward-Looking Statements;” the risk factors described in our Annual Report on Form 10-K and the following:

•

changes in general conditions in the economy, geopolitical events or the financial markets;

•

variations in our quarterly operating results;

•

changes in financial estimates by securities analysts;

•

our share repurchase or dividend policies;

•

other developments affecting us, our industry, customers or competitors;

•

changes in demand for our products or the prices we charge due to changes in economic conditions, competition or other factors;

•

general economic conditions in the markets where we operate;

•

the cyclical nature of our customers’ businesses and certain end markets that we service;

•

rental rate changes in response to competitive factors;

•

bankruptcy or insolvency of our customers, thereby reducing demand for our used units;

•

seasonal rental patterns;

•

acquisitions or divestitures and related costs;

•

labor shortages, work stoppages or other labor difficulties;

•

possible unrecorded liabilities of acquired companies;

•

possible write-offs or exceptional charges due to changes in applicable accounting standards, goodwill impairment, or divestiture or impairment of assets;

•

the operating and stock price performance of companies that investors deem comparable to us;

•

the number of shares available for resale in the public markets under applicable securities laws; and

•

the composition of our shareholder base.

Broad market fluctuations or any failure of our operating results in a particular quarter to meet market expectations may adversely affect the market price of shares of our Common Stock and the value of your investment. Occasionally, periods of volatility in the market price of a company’s securities may lead

TABLE OF CONTENTS

to the institution of securities class action litigation against a company. If we are subject to such volatility in the price of shares of our Common Stock, we may be the target of such securities litigation in the future. Such legal action could result in substantial costs to defend our interests and a diversion of management’s attention and resources, each of which would have a material adverse effect on our business and operating results and the market price of shares of Common Stock may decline.

Our largest stockholder may have the ability to influence our business and matters requiring approval by our stockholders.

Sapphire Holding, the Selling Stockholder, which is controlled by TDR Capital LLP (“TDR Capital”), beneficially owns approximately 27% of the issued and outstanding shares of our Common Stock (including unexercised warrants to purchase 2,425,000 additional shares of our Common Stock). Pursuant to a stockholders agreement entered into on July 1, 2020, by and among us and TDR Capital and certain of its affiliates, including Sapphire Holding, TDR Capital has the right to nominate two directors to our Board of Directors, for so long as TDR Capital beneficially owns at least 15% of our Common Stock and one director for so long as TDR Capital beneficially owns at least 5% of our Common Stock. Two directors nominated by Sapphire Holding currently serve on our Board of Directors. Sapphire Holding may have the ability to influence matters requiring approval by our stockholders, including the election and removal of directors, amendments to our certificate of incorporation and bylaws, any proposed merger, consolidation or sale of all or substantially all of our assets and certain other corporate transactions. Sapphire Holding may have interests that are different from those of other stockholders.

In August 2018, Sapphire Holding pledged all of the shares of WillScot’s Class A Common Stock that it owned as security for a margin loan under which Sapphire Holding borrowed $125.0 million (the “Margin Loan”). The Margin Loan was scheduled to mature on August 23, 2020. On August 21, 2020, Sapphire Holding entered into an amended and restated margin loan agreement which, among other things, extends the maturity date of the Margin Loan to August 29, 2022. As of December 31, 2020, 59,725,558 shares of Common Stock are pledged to secure repayment of amounts outstanding under the Margin Loan. An event of default under the Margin Loan could result in the foreclosure on the pledged securities and the sale by the lender of the pledged securities in the open market, which could cause the market price of our Common Stock to decline. Such an event could also result in another stockholder beneficially owning a significant amount of our Common Stock. There can be no assurance that Sapphire Holding will be able to extend, repay or refinance the loan on terms acceptable to it or at all.

Sales of a significant number of shares of our Common Stock in the public markets, or the perception of the likelihood of such sales, could depress the market price of shares of our Common Stock.

Sales of a substantial number of shares of our Common Stock in the public markets and the availability of those shares for sale could adversely affect the market price of our Common Stock. Such sales, or the perception in the market that holders of a large number of shares intend to sell shares, could depress the market price of our Common Stock and impair our ability to raise capital through the sale of additional equity securities. Under our existing Amended and Restated Registration Rights Agreement, dated November 29, 2017 (the “2017 Registration Rights Agreement”) by and among the Company and the investors party thereto, including an affiliate of TDR Capital, certain of the Company’s founders and certain transferees thereof (the “Registration Rights Parties”), the Registration Rights Parties have the right to request an unlimited number of demands, customary shelf registration rights, subject to certain conditions, and piggyback registration rights with respect to registration statements filed by us. In connection with the closing of our acquisition of Modular Space Holdings, Inc. (“ModSpace”), we entered into a registration rights agreement dated July 26, 2018 by and among the Company and certain of the sellers of ModSpace (the “ModSpace Investors”) who received the Common Stock and warrants as part of the consideration for the ModSpace Acquisition (the “2018 Registration Rights Agreement”). The 2018 Registration Rights Agreement provides the ModSpace Investors with the right to request an unlimited number of demands at any time and customary shelf registration rights, subject to certain conditions. The Registration Rights Parties and the ModSpace Investors may request that we include such Common Stock in certain future registration statements or offerings of Common Stock by us. We cannot predict the effect that future sales of Common Stock or other equity-related securities would have on the market price of our Common Stock.

TABLE OF CONTENTS

If securities or industry analysts cease to publish research, or publish inaccurate or unfavorable research about our business, our stock price and trading volume could decline.

The trading market for our Common Stock will depend, in part, on the research and reports that securities or industry analysts publish about us or our business. If one or more of the analysts who cover us downgrade our stock or publish inaccurate or unfavorable research about our business, our stock price would likely decline. In addition, if our operating results fail to meet the forecasts of analysts, our stock price would likely decline. If one or more of these analysts cease coverage of our company or fail to publish reports on us regularly, demand for our stock could decrease, which might cause our stock price and trading volume to decline.

We have not declared or paid dividends on our Common Stock.

As of the date of this prospectus, we have not declared or paid dividends on our Common Stock. Declaration or payments of dividends, if any, in the future, will be at the discretion of our Board of Directors and will depend on our then current financial condition, results of operations, capital requirements and other factors deemed relevant by our Board of Directors.

TABLE OF CONTENTS

SELLING STOCKHOLDER

This prospectus relates to the possible resale by the Selling Stockholder of up to 59,675,708 shares of Common Stock.

WillScot Mobile Mini was incorporated under the name Double Eagle Acquisition Corporation (“Double Eagle”) on June 26, 2015. Prior to November 29, 2017, Double Eagle was a Nasdaq-listed special purpose acquisition company formed for the purpose of effecting a merger, share exchange, asset acquisition, share purchase, reorganization or similar business combination. On November 29, 2017, Double Eagle indirectly acquired Williams Scotsman International, Inc. from Algeco Scotsman Global S.à r.l., which is majority-owned by an investment fund managed by TDR Capital. As part of the transaction (the “2017 Business Combination”), Double Eagle domesticated to Delaware and changed its name to WillScot Corporation.

In connection with the 2017 Business Combination, we issued 43,568,901 shares of our Common Stock in a private placement to Sapphire Holding, and granted certain registration rights to Sapphire Holding in connection therewith. As partial consideration for the 2017 Business Combination, we issued 8,024,419 shares of our Class B common stock, par value $0.0001 per share (the “Class B common stock”), pursuant to a Stock Purchase Agreement, dated November 6, 2017, by and among Double Eagle, Williams Scotsman Holdings Corp. (“Holdings”), Algeco Scotsman Global S.à r.l. (“Algeco Global”) and the other sellers party thereto. On December 6, 2017, Algeco Global transferred the 8,024,419 shares of Class B common stock to Sapphire Holdings pursuant to an exchange agreement (the “Exchange Agreement”) in respect of the 2017 Business Combination stock consideration and granted certain registration rights in connection therewith. Pursuant to an agreement between Sapphire Holding and Gerard E. Holthaus, a member of our board of directors, Sapphire Holding transferred 300,000 of these shares of Common Stock to Gerard E. Holthaus. Sapphire Holding further received a total of 5,765,625 shares of our Common Stock upon release, on January 19, 2018 and August 1, 2018, of such shares from escrow pursuant to the terms of an earnout agreement entered into by and among us, Sapphire Holding, Double Eagle Acquisition LLC and Harry E. Sloan concurrent with the closing of the 2017 Business Combination and for which Sapphire Holdings was similarly granted certain registration rights.

On June 30, 2020, in connection with the Merger, Sapphire Holdings exchanged each of its shares of common stock, par value $0.0001, of Holdings, a direct subsidiary of the Company, pursuant to the Exchange Agreement, for 1.3261 shares of newly issued Class A common stock (the “Sapphire Exchange”). As a result of the Sapphire Exchange, all 8,024,419 issued and outstanding shares of our Class B common stock were automatically canceled for no consideration and the existing exchange agreement was automatically terminated. As a result of the Sapphire Exchange, Holdings became a wholly-owned subsidiary of WillScot. Sapphire Holdings received 10,641,182 shares of Class A common stock in the Sapphire Exchange, which Class A Common Stock were reclassified and converted into our Common Stock in the Merger, as described above.

On July 1, 2020, WillScot combined with Mobile Mini in a stock-for-stock merger with WillScot as the surviving company and WillScot changed its name to WillScot Mobile Mini Holdings Corp. Immediately following the Merger, WillScot Mobile Mini filed an amended and restated certificate of incorporation, which reclassified all outstanding shares of WillScot Class A common stock and converted such shares into shares of common stock, par value $0.0001 per share, of WillScot Mobile Mini.

As of the date of this prospectus, the Selling Stockholder beneficially owned approximately 27% of the issued and outstanding shares of our Common Stock (including unexercised warrants to purchase 2,425,000 additional shares of our Common Stock). Pursuant to a stockholders agreement entered into on July 1, 2020, by and among us and TDR Capital and certain of its affiliates, including the Selling Stockholder, TDR Capital has the right to nominate two directors to our Board of Directors, for so long as TDR Capital beneficially owns at least 15% of our Common Stock and one director for so long as TDR Capital beneficially owns at least 5% of our Common Stock. Two directors nominated by the selling stockholder currently serve on our Board of Directors.

The Selling Stockholder is electing to register for resale 59,675,708 shares of Common Stock by the registration statement of which this prospectus forms a part.

PLAN OF DISTRIBUTION

We are registering 59,675,708 shares of Common Stock for possible sale by the Selling Stockholder. We will not receive any proceeds from the sale of shares of Common Stock by the Selling Stockholder pursuant to this prospectus. We are required to pay all fees and expenses incident to the registration of the shares of Common Stock to be offered and sold pursuant to this prospectus.

The shares of Common Stock beneficially owned by the Selling Stockholder covered by this prospectus may be offered and sold from time to time by the Selling Stockholder. The term “Selling Stockholder” includes donees, pledgees, transferees or other successors in interest selling securities received after the date of this prospectus from the Selling Stockholder as a gift, pledge, partnership distribution or other transfer. The Selling Stockholder will act independently of us in making decisions with respect to the timing, manner and size of each sale. Such sales may be made on one or more exchanges or in the over-the-counter market or otherwise, at prices and under terms then prevailing or at prices related to the then current market price or in negotiated transactions. Subject to the provisions of our Securities Trading Policy, the Selling Stockholder may sell its shares by one or more of, or a combination of, the following methods:

•

purchases by a broker-dealer as principal and resale by such broker-dealer for its own account pursuant to this prospectus;

•

ordinary brokerage transactions and transactions in which the broker solicits purchasers;

•

block trades in which the broker-dealer so engaged will attempt to sell the shares as agent but may position and resell a portion of the block as principal to facilitate the transaction;

•

an over-the-counter distribution in accordance with the rules of the Nasdaq Capital Market;

•

through trading plans entered into by a Selling Stockholder pursuant to Rule 10b5-1 under the Exchange Act, that are in place at the time of an offering pursuant to this prospectus and any applicable prospectus supplement hereto that provide for periodic sales of their securities on the basis of parameters described in such trading plans;

•

to or through underwriters or broker-dealers;

•

in “at the market” offerings, as defined in Rule 415 under the Securities Act, at negotiated prices, at prices prevailing at the time of sale or at prices related to such prevailing market prices, including sales made directly on a national securities exchange or sales made through a market maker other than on an exchange or other similar offerings through sales agents;

•

in privately negotiated transactions;

•

in options transactions;

through a combination of any of the above methods of sale; or

•

any other method permitted pursuant to applicable law.

In addition, any shares that qualify for sale pursuant to Rule 144 under the Securities Act may be sold under Rule 144 under the Securities Act rather than pursuant to this prospectus.

To the extent required, this prospectus may be amended or supplemented from time to time to describe a specific plan of distribution. Subject to the provisions of our Securities Trading Policy, which is applicable to members of our Board of Directors and certain of their affiliates. in connection with distributions of the shares or otherwise, the Selling Stockholder may enter into hedging transactions with broker-dealers or other financial institutions. In connection with such transactions, broker-dealers or other financial institutions may engage in short sales of shares of Common Stock in the course of hedging the positions they assume with Selling Stockholder. The Selling Stockholder may also sell shares of Common Stock short and redeliver the shares to close out such short positions. The Selling Stockholder may also enter into option or other transactions with broker-dealers or other financial institutions which require the delivery to such broker-dealer or other financial institution of shares offered by this prospectus, which shares such broker-dealer or other financial institution may resell pursuant to this prospectus (as supplemented or amended to reflect such transaction). The Selling Stockholder may also pledge shares to a broker-dealer or other financial

TABLE OF CONTENTS

institution, and, upon a default, such broker-dealer or other financial institution, may effect sales of the pledged shares pursuant to this prospectus (as supplemented or amended to reflect such transaction).

Subject to the provisions of our Securities Trading Policy, as applicable, the Selling Stockholder 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 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 the Selling Stockholder or borrowed from the Selling Stockholder or others to settle those sales or to close out any related open borrowings of stock, and may use securities received from any Selling Stockholder 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 will be identified in the applicable prospectus supplement (or a post-effective amendment). In addition, any Selling Stockholder 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. 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 effecting sales, broker-dealers or agents engaged by the Selling Stockholder may arrange for other broker-dealers to participate. Broker-dealers or agents may receive commissions, discounts or concessions from the Selling Stockholder in amounts to be negotiated immediately prior to the sale.

In offering the shares covered by this prospectus, the Selling Stockholder and any broker-dealers who execute sales for the Selling Stockholder may be deemed to be “underwriters” within the meaning of the Securities Act in connection with such sales. Any profits realized by the Selling Stockholder and the compensation of any broker-dealer may be deemed to be underwriting discounts and commissions.

In order to comply with the securities laws of certain states, if applicable, the shares must be sold in such jurisdictions only through registered or licensed brokers or dealers. In addition, in certain states the shares may not be sold unless they have been registered or qualified for sale in the applicable state or an exemption from the registration or qualification requirement is available and is complied with.

We have advised the Selling Stockholder that the anti-manipulation rules of Regulation M under the Exchange Act may apply to sales of shares in the market and to the activities of the Selling Stockholder and their affiliates. In addition, we will make copies of this prospectus available to the Selling Stockholder for the purpose of satisfying the prospectus delivery requirements of the Securities Act. The Selling Stockholder may indemnify any broker-dealer that participates in transactions involving the sale of the shares against certain liabilities, including liabilities arising under the Securities Act.

At the time a particular offer of shares is made, if required, a prospectus supplement will be distributed that will set forth the number of shares being offered and the terms of the offering, including the name of any underwriter, dealer or agent, the purchase price paid by any underwriter, any discount, commission and other item constituting compensation, any discount, commission or concession allowed or reallowed or paid to any dealer, and the proposed selling price to the public.

Our Certificate of Incorporation authorizes the issuance of 501,000,000 shares of capital stock, consisting of: (i) 500,000,000 shares of Common Stock and (ii) 1,000,000 shares of preferred stock.

Common Stock

This section describes the general terms and provisions of our Common Stock. For more detailed information, you should refer to our Certificate of Incorporation and Bylaws, copies of which have been filed with the SEC. These documents are also incorporated by reference into the registration statement of which this prospectus forms a part.

The holders of shares of Common Stock possess all voting power for the election of our directors and all other matters requiring stockholder action and will at all times vote together as one class on all matters properly submitted to a vote of the stockholders of the Company. Holders of Common Stock are entitled to one vote per share on matters to be voted on by stockholders, provided, however that, except as otherwise required by law, holders of Common Stock shall not be entitled to vote on any amendment to the Certificate of Incorporation (including any preferred designation) that relates solely to the terms of one or more outstanding series of preferred stock if the holders of such affected series are entitled, either separately or together as a class with the holders of one or more other such series, to vote thereon pursuant to the Certificate of Incorporation (including any preferred designation) or pursuant to the DGCL.

Holders of Common Stock will be entitled to receive dividends if and when declared by our Board of Directors out of funds legally available therefor and shall share equally on a per share basis in such dividends and distributions. The Board may set apart out of any of the funds of the Company available for dividends a reserve or reserves for any proper purpose and may abolish any such reserve. Upon liquidation, dissolution or winding-up of our Company, the holders of the Common Stock will be entitled to receive an equal amount per share of all of our assets available for distribution, after the rights of the holders of any preferred stock have been satisfied. Our stockholders have no preemptive, subscription, redemption or conversion rights and there are no sinking fund or redemption provisions applicable to our Common Stock. Delaware law and our Bylaws permit us to issue uncertificated shares of Common Stock by resolution of the Board. The rights, preferences and privileges of holders of Common Stock are subject to the rights of the holders of any series of preferred stock that the Company may designate and issue in the future.

Preferred Stock

This section describes the general terms and provisions of our preferred stock. For more detailed information, you should refer to our Certificate of Incorporation and Bylaws, copies of which have been

TABLE OF CONTENTS

filed with the SEC. These documents are also incorporated by reference into the registration statement of which this prospectus forms a part.

Preferred stock may be issued from time to time in one or more series.

Our Board is authorized, without stockholder approval, to 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 to issue preferred stock without stockholder approval could have the effect of delaying, deferring or preventing a change of control of us or the removal of existing management. We have no preferred stock outstanding at the date hereof.

Our Board of Directors will fix the designations, voting powers, preferences and rights of each series of preferred stock, as well as the qualifications, limitations or restrictions thereof, of the preferred stock of each series that we offer under any applicable prospectus or prospectus supplements in the certificate of designation relating to that series.

The DGCL provides that the holders of preferred stock will have the right to vote separately as a class (or, in some cases, as a series) on an amendment to our Certificate of Incorporation if the amendment would change the par value or, unless the Certificate of Incorporation provided otherwise, the number of authorized shares of the class or change the powers, preferences or special rights of the class or series so as to adversely affect the class or series, as the case may be. This right is in addition to any voting rights that may be provided for in the applicable certificate of designation.

Warrants

We have outstanding warrants exercisable for Common Stock, consisting of: (i) warrants issued in a private placement in connection with our initial public offering, each exercisable for one-half of one share of Common Stock (the “2015 Private Warrants); and (ii) the warrants, each exercisable for one share of Common Stock issued in connection with our acquisition of ModSpace (the “ModSpace Warrants”). The 2015 Private Warrants were issued under a warrant agreement dated September 10, 2015, between Continental Stock Transfer & Trust Company, as warrant agent, and Double Eagle (the “2015 Warrant Agreement”). The ModSpace Warrants were issued under a warrant agreement dated August 15, 2018, between Continental Stock Transfer & Trust Company, as warrant agent, and us (the “ModSpace Warrant Agreement”).

Private Warrants

The founders of Double Eagle and our former independent directors purchased 19,500,000 2015 Private Warrants at a price of $0.50 per Private Warrant for an aggregate purchase price of $9,750,000 in a private placement that occurred simultaneously with Double Eagle’s initial public offering. The 2015 Private Warrants became exercisable on December 29, 2017 and expire five years after that date, or earlier upon redemption or liquidation. The 2015 Private Warrants are exercisable for one-half of one share of our Common Stock for and exercise price of $5.75 per half share, subject to adjustment, at any time So long as the Private Warrants are held by the initial stockholders or their permitted transferees, such warrants may be exercised on a cashless basis and will not be redeemable by us. If the Private Warrants are held by holders other than the initial stockholders or their permitted transferees, each 2015 Private Warrant will be redeemable by us. If redeemable by us, we may call the 2015 Private Warrants for redemption in whole and not in part, at a price of $0.01 per warrant, upon not less than 30 days’ prior written notice of redemption to each warrant holder and if, and only if, the last reported sale price of the Common Stock equals or exceeds $18.00 per share for any 20 trading days within a 30-trading day period ending three business days before we send the notice of redemption to the warrant holders.

The 2015 Private Warrants may be exercised only for a whole number of shares of Common Stock. No fractional shares will be issued upon exercise of the 2015 Private Warrants. If, upon exercise of the 2015 Private Warrants, a holder would be entitled to receive a fractional interest in a share, we will, upon exercise, round down to the nearest whole number the number of shares of Common Stock to be issued to the 2015 Private Warrant holder.

The 2015 Private Warrant holders do not have the rights or privileges of holders of Common Stock and any voting rights until they exercise their 2015 Private Warrants and receive shares of Common Stock. After the issuance of shares of Common Stock upon exercise of the 2015 Private Warrants, each holder will be entitled to one vote for each share held of record on all matters to be voted on by stockholders.

The 2015 Private Warrants were issued under the 2015 Warrant Agreement. You should review a copy of the 2015 Warrant Agreement, filed as an exhibit to our Annual Report on Form 10-K, for a complete description of the terms and conditions applicable to such warrants.

TABLE OF CONTENTS

ModSpace Warrants

The ModSpace Warrants entitle the registered holder to purchase shares of Common Stock at an exercise price of $15.50 per share on a one to one basis, which may be adjusted in the event of an increase in the number of outstanding shares of Common Stock by share dividends (or a share split up or the payment of extraordinary dividends), a decrease in the number of shares of Common Stock by a consolidation, reverse split or similar transaction and in the in the event of certain reorganization transactions. Under the ModSpace Warrant Agreement, the ModSpace Warrants are not redeemable and may be replaced for replacement securities upon the occurrence of certain reorganization transactions of ours (other than those that would lead to an adjustment in the exercise price of the ModSpace Warrants). The ModSpace Warrants became exercisable on February 11, 2019, the 180th day after closing of the ModSpace Acquisition, and expire on November 29, 2022.

The ModSpace Warrants were issued under the ModSpace Warrant Agreement. You should review a copy of the ModSpace Warrant Agreement, filed as an exhibit to our Annual Report on Form 10-K, for a complete description of the terms and conditions applicable to such warrants.

Dividends

As of the date of this prospectus, we have not declared or paid dividends on our Common Stock. We have strong recurring cash flows, which gives us flexibility in how we allocate capital, and we review the appropriate mix of growth investments, debt reduction, and returns to shareholders on an ongoing basis. Declaration or payment of dividends, if any, in the future, will be at the discretion of our Board of Directors and will depend on our then current financial condition, results of operations, capital requirements and other factors deemed relevant by our Board of Directors.

Certain Anti-Takeover Provisions of Delaware Law, the Company’s Certificate of Incorporation and Bylaws

We are subject to Section 203 of the DGCL, which we refer to as “Section 203,” regulating corporate takeovers.

Section 203 prevents certain Delaware corporations, under certain circumstances, from engaging in a “business combination” with:

•

a stockholder who owns fifteen percent (15%) or more of our outstanding voting stock (otherwise known as an “interested stockholder”);

•

an affiliate of an interested stockholder; or

•

an associate of an interested stockholder, for three years following the date that the stockholder became an interested stockholder.

A “business combination” includes a merger or sale of more than ten percent (10%) of our assets. However, the above provisions of Section 203 do not apply if:

•

our Board approves the transaction that made the stockholder an “interested stockholder,” prior to the date of the transaction;

•

after the completion of the transaction that resulted in the stockholder becoming an interested stockholder, that stockholder owned at least eighty-five percent (85%) of our voting stock outstanding at the time the transaction commenced, other than statutorily excluded shares of common stock; or

•

on or subsequent to the date of the transaction, the business combination is approved by our Board and authorized at a meeting of our stockholders, and not by written consent, by an affirmative vote of at least two-thirds of the outstanding voting stock not owned by the interested stockholder.

Our Certificate of Incorporation, Bylaws and the DGCL contain provisions that could have the effect of rendering more difficult, delaying or preventing an acquisition deemed undesirable by our Board. These provisions could also make it difficult for stockholders to take certain actions, including electing directors who are not nominated by the members of our Board or taking other corporate actions, including effecting changes in our management. For instance, our Certificate of Incorporation provides that our Board is

TABLE OF CONTENTS

classified into three classes of directors. As a result, in most circumstances, a person can gain control of our Board only by successfully engaging in a proxy contest at three or more annual meetings.

In addition, our Certificate of Incorporation does not provide for cumulative voting in the election of directors. Our Board is empowered to elect a director to fill a vacancy created by the expansion of the Board or the resignation, death, or removal of a director in certain circumstances; and our advance notice provisions require that stockholders must comply with certain procedures in order to nominate candidates to our Board or to propose matters to be acted upon at a stockholders’ meeting.

Our Bylaws provide that, except as otherwise required by law, special meetings of stockholders for any purpose or purposes may be called at any time only by the Board, the Chairman of the Board, or the Chief Executive Officer of the Company, to be held at such date and time as shall be designated in the notice or waiver of notice thereof. Only business within the purposes described in the Corporation’s notice of meeting may be conducted at the special meetings. The ability of the stockholders to call a special meeting is specifically denied.

Our Bylaws also provide our Board with discretion in postponing stockholder meetings, including, within certain limits, special meetings of stockholders. Additionally, our chairman or Board (acting by resolution) may adjourn a stockholder meeting at any time prior to the transaction of business at such meeting, within certain limits. Our Bylaws also include additional procedures that apply to stockholder actions by written consent.

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.

Stockholders Rights Plan

The Company does not have a stockholder rights plan currently in effect.

Rule 144

Pursuant to Rule 144 of the Securities Act (“Rule 144”), a person who has beneficially owned restricted shares of our Common Stock or warrants for at least six months would be entitled to sell their securities, provided that (i) such person is not deemed to have been one of our affiliates at the time of, or at any time during the three months preceding, a sale and (ii) we are subject to the Exchange Act periodic reporting requirements for at least three months before the sale and have filed all required reports under Section 13 or 15(d) of the Exchange Act during the 12 months (or such shorter period as we were required to file reports) preceding the sale.

Persons who have beneficially owned restricted shares of our Common Stock or warrants for at least six months but who are our affiliates at the time of, or at any time during the three months preceding, a sale, would be subject to additional restrictions, by which such person would be entitled to sell within any three-month period only a number of securities that does not exceed the greater of:

•

one percent (1%) of the total number of shares of common stock then outstanding; or

•

the average weekly reported trading volume of the common stock during the four calendar weeks preceding the filing of a notice on Form 144 with respect to the sale.

Sales by our affiliates under Rule 144 are also limited by manner of sale provisions and notice requirements and to the availability of current public information about us.

The transfer agent, warrant agent and escrow agent for our Common Stock and warrants is Continental Stock Transfer & Trust Company.
