FORWARD-LOOKING STATEMENTS

This prospectus, the documents incorporated by reference herein, and any free writing prospectus that we authorize for use in connection with this offering may contain forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995. Forward-looking statements include, among other things, information concerning our future results of operations and financial position, strategy and plans, and our expectations for future operations. Forward-looking statements include all statements that are not historical facts and, in some cases, can be identified by terms such as “anticipate,” “believe,” “contemplate,” “continue,” “could,” “design,” “estimate,” “expect,” “intend,” “may,” “plan,” “possible,” “potential,” “predict,” “project,” “seek,” “should,” “target,” “will,” “would” or the negative version of these words and similar expressions.

Many factors could affect our actual results, and variances from our current expectations regarding these factors could cause actual results to differ materially from those expressed in our forward-looking statements. We presently consider the factors set forth below to be important factors that could cause actual results to differ materially from our published expectations. A more detailed discussion of these factors, as well as other factors that could affect our results, is contained under the heading “Risk Factors” in our Annual Report on Form 10-K for the year ended June 30, 2023, as updated by our subsequent quarterly reports on Form 10-Q and other filings we make with the SEC. However, management cannot predict all factors, or combinations of factors, that may cause actual results to differ materially from those projected in any forward-looking statements. Factors that we currently believe could cause our results to be different from our expectations include:

Operational and Execution Risks

• Adverse economic conditions may harm our business.

• Recent events in eastern Europe and the Taiwan Strait present challenges and risks to us, and no assurances can be given that current or future developments would not have a material adverse effect on our business, results of operations and financial condition.

• Our quarterly operating results have fluctuated and will likely fluctuate in the future.

• Our revenue and margins for a particular period are difficult to predict, and a shortfall in revenue or decline in margins may harm our operating results.

• As we increasingly target larger customers and larger sales opportunities, our customer base may become more concentrated, our cost of sales may increase, our margins may be lower, our borrowings may be higher with effects on our cash flow, we are exposed to inventory risks, and our sales may be less predictable.

• If we fail to meet any publicly announced financial guidance or other expectations about our business, it could cause our stock to decline in value.

• We may be unable to secure additional financing on favorable terms, or at all, which in turn could impair the rate of our growth.

• Increases in average selling prices for our Total IT Solutions have historically significantly contributed to increases in net sales in some of the periods covered. Such prices are subject to decline if customers do not continue to purchase our latest generation products or additional components, which could harm our results of operations.

• Our cost structure and ability to deliver server solutions to customers in a timely manner may be adversely affected by volatility of the market for core components and certain materials for our products.

• We may lose sales or incur unexpected expenses relating to insufficient, excess or obsolete inventory.

• Difficulties we encounter relating to automating internal controls utilizing our ERP systems or integrating processes that occur in other IT applications could adversely impact our controls environment.

• System security violations, data protection breaches, cyber-attacks and other related cyber-security issues could disrupt our internal operations or compromise the security of our products, and any such disruption could reduce our expected revenues, increase our expenses, damage our reputation and adversely affect our stock price.

ii

• Any failure to adequately expand or retain our sales force will impede our growth.

• Conflicts of interest may arise with Ablecom and Compuware, which are related parties, and they may adversely affect our operations.

• Our reliance on Ablecom could be subject to risks associated with our reliance on a limited source of contract manufacturing services and inventory warehousing.

• If negative publicity arises with respect to us, our employees, our third-party service providers or our partners, our business and operating results could be adversely affected, regardless of whether the negative publicity is true.

• If we lose Charles Liang, our President, Chief Executive Officer and Chairman, or any other key employee, we may not be able to implement our business strategy in a timely manner.

• Our direct sales efforts may create confusion for our end customers and harm our relationships in our indirect sales channel and with our OEMs.

• If we are unable to attract and integrate additional key employees in a manner that enables us to scale our business and operations effectively, or if we do not maintain competitive compensation policies to retain our employees, our ability to operate effectively and efficiently could be limited.

Strategic and Industry Risks

• If we do not successfully manage the expansion of our international manufacturing capacity and business operations, our business could be harmed.

• We may not be able to successfully manage our business for growth and expansion.

• Our growth into markets outside the United States exposes us to risks inherent in international business operations.

• We depend upon the development of new products & enhancements to existing products. If we fail to predict or respond to emerging technological trends & our customers’ changing needs, our operating results and market share may suffer.

• The market in which we participate is highly competitive.

• Industry consolidation may lead to increased competition and may harm our operating results.

• We must work closely with our suppliers to make timely new product introductions.

• Our suppliers’ failure to improve the functionality and performance of materials and key components for our products may impair or delay our ability to deliver innovative products to our customers.

• We rely on a limited number of suppliers for certain components used to manufacture our products.

• We rely on indirect sales channels and any disruption in these channels could adversely affect our sales.

• Our failure to deliver high quality server and storage solutions could damage our reputation and diminish demand for our products.

• Our results of operations may be subject to fluctuations based upon our investment in corporate ventures.

Legal and Regulatory Risks

• Because our products and services may store, process and use data, some of which contains personal information, we are subject to complex and evolving laws and regulations regarding privacy, data protection and other matters.

• Our operations could involve the use of regulated materials, and we must comply with environmental, health and safety laws and regulations, which can be expensive.

iii

• If we are unable to maintain effective internal control over financial reporting, investors may lose confidence in the accuracy and completeness of our financial reports and the market price of our common stock may decrease.

• Failure to comply with the U.S. Foreign Corrupt Practices Act, other applicable anti-corruption and anti-bribery laws, and applicable trade control laws could subject us to penalties and other adverse consequences.

• Any failure to protect our intellectual property could impair our brand and our competitiveness.

• Resolution of claims that we have violated or may violate the intellectual property rights of others could require us to indemnify others or pay significant royalties to third parties.

• Provisions of our governance documents and Delaware law might discourage, delay or prevent a change of control of our company or changes in our management.

Financial Risks

• Our R&D expenditures, as a percentage of our net sales, are considerably higher than many of our competitors.

• Our future effective income tax rates could be affected by changes in the relative mix of our operations and income among different geographic regions and by changes in domestic and foreign income tax laws.

• Backlog does not provide a substantial portion of our net sales in any quarter.

Risks Related to Owning our Common Stock

• The trading price of our common stock is likely to be volatile.

• Future sales of shares by existing stockholders, including any shares that have vested or may in the future vest under the 2021 CEO Performance Award or 2023 CEO Performance Award, could cause our stock price to decline.

• The concentration of our capital stock ownership with insiders likely limits your ability to influence corporate matters.

• We do not expect to pay any cash dividends for the foreseeable future.

General Risks

• Our products may not be viewed as supporting climate change mitigation in the IT sector.

• Our business and operations may be impacted by natural disaster events, including those brought on by climate change.

• The use of AI by our workforce may present risks to our business.

• Expectations relating to environmental, social and governance considerations expose us to potential liabilities, reputational harm and other unforeseen adverse effects on our business.

PROSPECTUS SUMMARY

You should read the following prospectus summary together with the entire prospectus and the documents incorporated by reference herein, including our consolidated financial statements and related notes as well as any free writing prospectus prepared by us or on our behalf in connection with this offering. You should carefully consider, among other things, the matters discussed in the sections entitled “Risk Factors” included in or incorporated by reference in this prospectus.

SUPER MICRO COMPUTER, INC.

Our Company

We are a Silicon Valley-based provider of accelerated compute platforms that are application-optimized high performance and high-efficiency server and storage systems for a variety of markets, including enterprise data centers, cloud computing, artificial intelligence (“AI”), 5G and edge computing. Our Total IT Solutions include complete servers, storage systems, modular blade servers, blades, workstations, full rack scale solutions, networking devices, server sub-systems, server management and security software. We also provide global support and services to help our customers install, upgrade and maintain their computing infrastructure. We offer our customers a high degree of flexibility and customization by providing a broad array of server models and configurations from which they can choose the best solutions to fit their computing needs. Our server and storage systems, sub-systems and accessories are architecturally designed to provide high levels of reliability, quality, configurability, and scalability.

Our in-house design competencies, design control over many of the components used within our server and storage systems, and our Server Building Block Solutions^® (an innovative, modular and open architecture) enable us to rapidly develop, build and test our compute platforms along with our server and storage systems, sub-systems and accessories with unique configurations. As a result, when new technologies are brought to market, we are generally able to quickly assemble a broad portfolio of solutions by leveraging common building blocks across product lines. We work closely with the leading microprocessor, graphics processing units, memory, disk/flash, and interconnect vendors and other hardware and software suppliers to coordinate our new products’ design with their product release schedules. This enhances our ability to introduce new products incorporating the latest technology rapidly. We seek to be the first to market with products incorporating new technologies and to offer the broadest selection of products using those technologies to our customers.

To reduce the high cost of operating datacenters, IT managers increasingly turn to suppliers of high-performance products that are also cost-effective, energy-efficient, and green. Our resource saving architecture supports our efforts to lead in green IT innovation. This architecture disaggregates CPU and memory, which enables each resource to be refreshed independently, thereby allowing data centers to significantly reduce both refresh cycle costs and e-waste. In addition, we offer product lines that are designed to share common computing resources, thereby saving both valuable space and power as compared to general-purpose rackmount servers. We believe our approach of leveraging an overall architecture that balances data center power requirements, cooling, shared resources and refresh cycles helps the environment and provides total cost of ownership (“TCO”) savings for our customers.

We conduct our operations principally from our Silicon Valley headquarters, Taiwan and Netherlands facilities. Our sales and marketing activities operate through a combination of our direct sales force and indirect sales channel partners. We work with distributors, value-added resellers, system integrators, and original equipment manufacturers (“OEMs”) to market and sell our optimized solutions to their end customers in our indirect sales channels.

Industry and Strategy

Our objective is to be the world’s leading provider of solutions using accelerated compute platforms that are application-optimized offering high-performance server, storage and

2

networking. Achieving this objective requires continuous development and innovation of our Total IT Solutions with better price-performance and architectural advantages compared with our prior generation of solutions and with solutions offered by our competitors. Through our strategy, we seek to maintain or improve our relative competitive position in many product areas and pursue markets that provide us with additional long-term growth opportunities. Based on data from MarketData and IDC, from 2021 to 2023, our growth has been more than three times our industry’s average. As of Q3 2023, we had a production capacity of 4,000 racks per month and believe we have a path to significantly increasing our liquid cooling rack capacity over the next few quarters. Key elements of our strategy include executing upon the following:

• A Strong Internal Research and Development and Internal Manufacturing Capability

• Introducing More Innovative Products, Faster

• Capitalizing on New Applications and Technologies

• Driving Software and Services Sales to our Global Enterprise Customers

• Leveraging Our Global Operating Structure

RISK FACTORS

Investing in our common stock involves a high degree of risk. You should consider carefully the risks and uncertainties described in this section and in the section entitled “Risk Factors” contained in our most recent Annual Report on Form 10-K, as well as any amendments thereto reflected in subsequent filings with the SEC, which are incorporated by reference into this prospectus in their entirety, together with all of the other information contained in this prospectus or any document incorporated by reference herein and any free writing prospectus that we may authorize for use in connection with this offering. The risks described in this prospectus or any document incorporated by reference herein are not the only risks facing us. Additional risks and uncertainties not currently known or that we currently deem to be immaterial also may materially adversely affect our business, financial condition and/or operating results. Many of the following risks and uncertainties and those contained in the documents incorporated by reference herein may be exacerbated by any worsening of the global business and economic environment. If any of the unfavorable events or circumstances described in the risk factors actually occurs, our business may suffer, the trading price of our common stock and other securities could decline, and you could lose all or part of your investment.

Risks Relating to This Offering and Ownership of Our Common Stock

The trading price of our common stock has been and may in the future be volatile, and you might not be able to sell your shares at or above the price at which you purchased the shares.

The trading prices of technology company securities historically have been highly volatile. In addition, the global markets have been volatile, and experienced volatility as a result of macroeconomic conditions such as heightened inflation, increased interest rates, armed conflict and related sanctions and trade restrictions and the effects of the COVID-19 pandemic. The trading price of our common stock is likely to be subject to fluctuations in response to numerous factors, many of which are beyond our control, such as those discussed in the “Risk Factors” section contained in our Annual Report on Form 10-K for the year ended June 30, 2023 and others, including:

• Actual or anticipated variations in our operating results, including failure to achieve previously provided guidance;

• Announcements of technological innovations, new products or product enhancements, strategic alliances or significant agreements by us or by our competitors;

• Changes in recommendations by any securities analysts that elect to follow our common stock;

• The financial projections we may provide to the public, any changes in these projections or our failure to meet these projections;

• False or misleading press releases or articles regarding our company or our products;

• The loss of a key customer;

• The loss of key personnel;

• Technological advancements rendering our products less valuable;

• Lawsuits filed against us;

• Changes in operating performance and stock market valuations of other companies that sell similar products;

• Price and volume fluctuations in the overall stock market;

• Market conditions in our industry, the industries of our customers and the economy as a whole; and

• Other events or factors, including those resulting from war, incidents of terrorism, political instability, pandemics or responses to these events.

If the trading price of our common stock after this offering does not exceed the public offering price, you would not realize any return on your investment in this offering and may lose some or all of your investment.

Future sales and issuances of our common stock or rights to purchase common stock, including pursuant to our equity incentive plans or in connection with commercial transactions, could result in additional dilution of the percentage ownership of our stockholders and could cause the price of our common stock to decline.

From time to time, we may issue additional securities or sell common stock, convertible securities, or other equity securities in one or more transactions at prices and in a manner we determine. We also expect to continue to issue common stock to employees and directors pursuant to our equity incentive plans. If we sell or issue common stock, convertible securities, or other equity securities, or common stock is issued pursuant to equity incentive plans, investors in our common stock may be materially diluted.

Our executive officers, directors and selling stockholders have entered into lock-up agreements with the underwriters under which they have agreed, subject to specific exceptions, not to sell, directly or indirectly, any shares of common stock without the permission of J.P. Morgan Securities LLC for a period of 60 days after the date of the pricing of this offering. Sales of a substantial number of such shares upon expiration of the lock-up agreements, the perception that such sales may occur or early release of these agreements could cause our market price to fall or make it more difficult for you to sell your common stock at a time and price that you deem appropriate.

Our management team may invest or spend the net proceeds of this offering in ways with which you may not agree or in ways which may not yield significant return.

Our management will have broad discretion over the use of the net proceeds from this offering. We currently intend to use the net proceeds from this offering for working capital and general corporate purposes. You will not have the opportunity, as part of your investment decision, to assess whether the proceeds are being used appropriately. The net proceeds may be used for working capital and corporate purposes that do not improve our operating results or enhance the value of our common stock.

Purchasers of shares of our common stock in this offering will experience immediate and substantial dilution in the book value of their investment.

If you purchase shares of our common stock in this offering at an assumed public offering price of $289.03 per share, the last reported sales price for our common stock on the Nasdaq Global Select Market on November 29, 2023, you will incur immediate and substantial dilution in the as adjusted net tangible book value of your stock because the price that you pay will be substantially greater than the net tangible book value per share of the shares you acquire. To the extent we raise additional capital by issuing additional shares of common stock, convertible securities, or other equity securities, our stockholders will experience substantial additional dilution.

We do not expect to pay any cash dividends for the foreseeable future.

We do not anticipate that we will pay any cash dividends to holders of our common stock in the foreseeable future. In addition, under the terms of one of our credit agreements, we cannot pay any dividends, with limited exceptions. Accordingly, investors should rely on sales of their common stock after price appreciation, which may never occur, as the only way to realize any future gains on their investment.

10

USE OF PROCEEDS

We estimate that the net proceeds to us from the issuance of our common stock in this offering, after deducting estimated underwriting discounts and commissions and estimated offering expenses payable by us, will be approximately $503.5 million, or approximately $582.9 million if the underwriters exercise their option to purchase additional shares in full. We will not receive any proceeds from the sale of shares of common stock by the selling stockholders.

The principal purpose of this offering is to obtain additional capital to support our operations, including working capital needs, manufacturing capacity expansion and increased R&D investments. We have not yet determined the manner in which we will allocate the net proceeds from this offering, and as a result, management will have broad discretion in the allocation and use of the net proceeds. Pending the application of the net proceeds, we intend to invest the net proceeds in short-term, interest-bearing, investment-grade securities.

DIVIDEND POLICY

No cash dividends have ever been paid or declared on our common stock. We currently intend to retain all future earnings, if any, for use in our business and do not anticipate paying any cash dividends on our common stock in the foreseeable future. Any future determination to declare cash dividends will be made at the discretion of our Board of Directors, subject to applicable laws and restrictions in our credit arrangements, and will depend on our financial condition, results of operations, capital requirements, general business conditions and other factors our Board of Directors may deem relevant. Under the terms of the credit agreement with Bank of America, as amended, we may not pay any dividends.

SELLING STOCKHOLDERS

Beneficial Ownership

The following table sets forth the beneficial ownership of our common stock by the selling stockholders, before and after giving effect to this offering by the selling stockholders.

The amounts and percentages of shares beneficially owned are reported on the basis of rules and regulations of the SEC governing the determination of beneficial ownership of securities. Under rules of the SEC, a person is deemed to be a “beneficial owner” of a security if that person has or shares voting power 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. Securities that can be so acquired are deemed to be outstanding for purposes of computing such person’s ownership percentage, but not for purposes of computing any other person’s percentage. Under these rules, more than one person may be deemed to be a beneficial owner of the same securities, and a person may be deemed to be a beneficial owner of securities as to which such person has no economic interest. The address for the beneficial owner is set forth in the footnote to the table.

Percentage computations are based on 53,538,116 shares of our common stock outstanding as of November 24, 2023.

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

The following is a general discussion of the material U.S. federal income tax considerations with respect to the ownership and disposition of shares of our common stock applicable to non-U.S. holders (as defined below) who acquire such shares in this offering and hold such shares as a capital asset within the meaning of Section 1221 of the Internal Revenue Code of 1986, as amended, or the Code, (generally, property held for investment). For purposes of this discussion, a “non-U.S. holder” means a beneficial owner of our common stock (other than an entity or arrangement that is treated as a partnership for U.S. federal income tax purposes) that is not, for U.S. federal income tax purposes, any of the following:

• an individual citizen or resident of the United States;

• a corporation (or other 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, any state thereof or the District of Columbia, or any other corporation treated as such;

• an estate, the income of which is includable in gross income for U.S. federal income tax purposes regardless of its source; or

• a trust if (i) a court within the United States is able to exercise primary supervision over the administration of the trust and one or more “U.S. persons,” as defined under the Code, have the authority to control all substantial decisions of the trust or (ii) such trust has made a valid election to be treated as a U.S. person for U.S. federal income tax purposes.

This discussion is based on current provisions of the Code, existing, temporary and proposed Treasury regulations promulgated thereunder, or Treasury Regulations, judicial opinions, published positions of the Internal Revenue Service, or the IRS, and other applicable authorities, all of which are subject to change (possibly with retroactive effect). This discussion does not address all aspects of U.S. federal income taxation that may be important to a particular non-U.S. holder in light of that non-U.S. holder’s individual circumstances, nor does it address any aspects of the unearned income Medicare contribution tax, any U.S. federal estate and gift taxes, any U.S. alternative minimum taxes or any state, local or non-U.S. taxes. This discussion may not apply, in whole or in part, to particular non-U.S. holders in light of their individual circumstances or to non-U.S. holders subject to special treatment under the U.S. federal income tax laws (such as taxpayers that elect mark-to-market accounting, insurance companies, tax-exempt organizations, tax- qualified retirement plans, financial institutions, brokers or dealers in securities, pension plans, “controlled foreign corporations,” “passive foreign investment companies,” corporations organized outside of the United States, any state thereof or the District of Columbia that are nonetheless treated as U.S. taxpayers for U.S. federal income tax purposes, non-U.S. holders that hold our common stock as part of a straddle, conversion transaction or other integrated investment, and certain U.S. expatriates and former citizens or long-term residents of the United States).

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 therein will generally depend on the status of the partner and the activities of the partnership. Partners of a partnership holding our common stock should consult their tax advisors as to the particular U.S. federal income tax consequences applicable to them.

THIS SUMMARY IS NOT INTENDED TO CONSTITUTE A COMPLETE DESCRIPTION OF ALL TAX CONSEQUENCES FOR NON-U.S. HOLDERS RELATING TO THE OWNERSHIP AND DISPOSITION OF OUR COMMON STOCK. PROSPECTIVE INVESTORS IN OUR COMMON STOCK SHOULD CONSULT THEIR TAX ADVISORS REGARDING THE TAX CONSEQUENCES TO THEM (INCLUDING THE APPLICATION AND EFFECT OF ANY STATE, LOCAL, ESTATE, NON-U.S. INCOME AND OTHER TAX LAWS) OF THE OWNERSHIP AND DISPOSITION OF OUR COMMON STOCK.

13

Distributions

As described in the section entitled “Dividend Policy,” we do not anticipate declaring or paying dividends to holders of our common stock in the foreseeable future. However, if we do make distributions of cash or property on our common stock, such distributions 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. Amounts not treated as dividends for U.S. federal income tax purposes will constitute a return of capital and first be applied against and reduce a non-U.S. holder’s adjusted tax basis in its common stock, but not below zero. Any excess will be treated as capital gain and will be treated as described below under “—Gain on Sale or Other Disposition of Common Stock.”

Subject to the discussion below on effectively connected income, dividends paid to a non-U.S. holder will be subject to U.S. federal withholding tax at a rate of 30% of the gross amount of the dividends (or such lower rate as may be specified by an applicable income tax treaty, provided the non-U.S. holder furnishes a valid IRS Form W-8BEN or W-8BEN-E (or other applicable documentation) certifying qualification for the lower treaty rate). A non-U.S. holder that does not timely furnish the required documentation, but that qualifies for a reduced treaty rate, may obtain a refund of any excess amounts withheld by timely filing an appropriate claim for refund with the IRS. Non-U.S. holders should consult their tax advisors regarding their entitlement to benefits under any applicable income tax treaty.

If dividends paid to a non-U.S. holder are effectively connected with the non-U.S. holder’s conduct of a trade or business within the United States (and, if required by an applicable income tax treaty, the non-U.S. holder maintains a permanent establishment in the United States to which such dividends are attributable), the non-U.S. holder will be exempt from the U.S. federal withholding tax described above. To claim the exemption, the non-U.S. holder must furnish to the applicable withholding agent a valid IRS Form W-8ECI, certifying that the dividends are effectively connected with the non-U.S. holder’s conduct of a trade or business within the United States.

Any such effectively connected dividends will be subject to U.S. federal income tax on a net income basis at the regular rates. A Non-U.S. Holder that is a corporation also may 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 such effectively connected dividends, as adjusted for certain items. Non-U.S. holders should consult their tax advisors regarding any applicable tax treaties that may provide for different rules.

Gain on Sale or Other Disposition of Common Stock

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

• the gain is effectively connected with a trade or business carried on by the non-U.S. holder within the United States (and, if required by an applicable tax treaty, is attributable to a U.S. permanent establishment of such non-U.S. holder);

• the non-U.S. holder is an individual and is present in the United States for 183 days or more in the taxable year of disposition and certain other conditions are met; or

• we are or have been a “United States real property holding corporation” (as defined in the Code) for U.S. federal income tax purposes at any time within the shorter of the five-year period preceding such disposition and such non-U.S. holder’s holding period of our common stock.

Gain that is effectively connected with the conduct of a trade or business in the United States (or so treated) generally will be subject to U.S. federal income tax on a net-income tax basis, at regular U.S. federal income tax rates. If the non-U.S. holder is a foreign corporation, the branch profits tax described above also may apply to such effectively connected gain, as adjusted for certain items. An individual non-U.S. holder who is subject to U.S. federal income tax because the non-U.S. holder was present in the United States for 183 days or more during the year of sale or other disposition of our common stock will be subject to a flat 30% tax on the gain derived from such sale or other disposition (or such lower rate as may be specified by an applicable

14

income tax treaty), which may be offset by U.S.-source capital losses, provided that the non-U.S. holder has timely filed U.S. federal income tax returns with respect to such losses. We believe that we are not, and we do not anticipate becoming, a United States real property holding corporation, or a USRPHC, for U.S. federal income tax purposes. Because the determination of whether we are a USRPHC depends, however, on the fair market value of our United States real property interests, or 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 we currently are not a USRPHC or will not become one in the future. Even if we are or were to become a USRPHC, gain arising from the sale or other taxable disposition of our common stock by a non-U.S. holder will not be subject to U.S. federal income tax if our common stock is “regularly traded,” as defined by applicable Treasury Regulations, on an established securities market and such non-U.S. holder owned, actually and constructively, 5% or less of our common stock throughout the shorter of the five-year period ending on the date of the sale or other taxable disposition or the non-U.S. holder’s holding period.

NON-U.S. HOLDERS SHOULD CONSULT THEIR TAX ADVISORS REGARDING ANY APPLICABLE TAX TREATIES THAT MAY PROVIDE FOR DIFFERENT RULES.

Withholdable Payments to Foreign Financial Entities and Other Foreign Entities

Under provisions of the Code known as the Foreign Account Tax Compliance Act, or FATCA, withholding tax of 30% may apply to certain payments to foreign financial institutions, investment funds and certain other non-U.S. persons that fail to comply with certain information reporting and certification requirements pertaining to their direct and indirect U.S. securityholders and/or U.S. accountholders and do not otherwise qualify for an exemption. Under applicable Treasury Regulations and IRS guidance, this withholding currently applies to payments of dividends, if any, on, and, subject to the proposed Treasury Regulations discussed below, gross proceeds from the sale or other disposition of, our common stock. An intergovernmental agreement between the U.S. and a foreign country may modify the requirements described in this paragraph.

Although withholding under existing FATCA regulations would also apply to payments of gross proceeds from the sale or other disposition of stock on or after January 1, 2019, proposed Treasury Regulations eliminate FATCA withholding on payments of gross proceeds entirely. Taxpayers generally may rely on these proposed Treasury Regulations until final Treasury Regulations are issued.

Prospective investors are encouraged to consult with their own tax advisors regarding the possible implications of FATCA on their investment in our common stock.

Backup Withholding, Information Reporting and Other Reporting Requirements

The applicable withholding agent must report annually to the IRS and to each non-U.S. holder the amount of dividends paid to, and the tax withheld with respect to, each non-U.S. holder. These reporting requirements apply to any distribution on our common stock regardless of whether such distributions constitute dividends or whether withholding was reduced or eliminated by an applicable tax treaty. Copies of this information reporting may also be made available under the provisions of a specific tax treaty or agreement with the tax authorities in the country in which the non-U.S. holder resides or is established.

A non-U.S. holder will generally be subject to backup withholding with respect to dividends on our common stock paid to it unless the non-U.S. holder certifies under penalties of perjury that, among other things, it is not a U.S. person (and the payor does not have actual knowledge or reason to know that the non-U.S. holder is a U.S. person), typically on a properly executed IRS Form W-8BEN, W-8BEN-E or other appropriate IRS Form W-8 (or any successor or substitute form thereof), or otherwise establishes an exemption.

Information reporting and backup withholding generally are not required with respect to the amount of any proceeds from the sale or other disposition of our common stock by a non-U.S. holder outside the United States through a foreign office of a foreign broker that does not have certain specified connections to the United States. However, if a non-U.S. holder sells or otherwise disposes of its shares of common stock through a U.S. broker or the U.S. offices of a foreign broker, the broker will generally be required to report the amount

15

of proceeds paid to the non-U.S. holder to the IRS and impose backup withholding on that amount unless such non-U.S. holder provides appropriate certification to the broker of its status as a non-U.S. person (and the payor does not have actual knowledge or reason to know that the non-U.S. holder is a U.S. person), typically on a properly executed IRS Form W-8BEN, W-8BEN-E or other appropriate IRS Form W-8 (or any successor or substitute form thereof), or otherwise establishes an exemption.

Backup withholding is not an additional income tax. Any amounts withheld under the backup withholding rules from a payment to a non-U.S. holder generally can be credited against the non-U.S. holder’s U.S. federal income tax liability, if any, or refunded, provided that the required information is furnished to the IRS in a timely manner. Non-U.S. holders should consult their tax advisors regarding the application of the information reporting and backup withholding rules to them.

THE PRECEDING DISCUSSION OF U.S. FEDERAL TAX CONSIDERATIONS IS FOR GENERAL INFORMATION PURPOSES ONLY. IT IS NOT TAX ADVICE. EACH PROSPECTIVE INVESTOR SHOULD CONSULT ITS OWN TAX ADVISOR REGARDING THE PARTICULAR U.S. FEDERAL, GIFT, ESTATE, STATE, LOCAL, AND NON-U.S. TAX CONSEQUENCES OF PURCHASING, HOLDING, AND DISPOSING OF OUR COMMON STOCK, INCLUDING THE CONSEQUENCES OF ANY PROPOSED CHANGE IN APPLICABLE LAWS.

We and the selling stockholders are offering the shares of common stock described in this prospectus through a number of underwriters. J.P. Morgan Securities LLC, BofA Securities, Inc. and Goldman Sachs & Co, LLC are acting as joint book-running managers of the offering and as representatives of the underwriters. We and the selling stockholders have entered into an underwriting agreement with the representatives. Subject to the terms and conditions of the underwriting agreement, we and the selling stockholders have agreed to sell to the underwriters, and each underwriter has severally agreed to purchase, at the public offering price less the underwriting discounts and commissions set forth on the cover page of this prospectus, the number of shares of common stock listed next to its name in the following table:

The underwriters are committed to purchase all the common shares offered by us and the selling stockholders if they purchase any shares. The underwriting agreement also provides that if an underwriter defaults, the purchase commitments of non-defaulting underwriters may also be increased or the offering may be terminated.

The underwriters propose to offer the common shares directly to the public at the initial public offering price set forth on the cover page of this prospectus and to certain dealers at that price less a concession not in excess of $5.895 per share. Any such dealers may resell shares to certain other brokers or dealers at a discount of up to $1.965 per share from the initial public offering price. After the initial offering of the shares to the public, if all of the common shares are not sold at the initial public offering price, the underwriters may change the offering price and the other selling terms. Sales of any shares made outside of the United States may be made by affiliates of the underwriters. The offering of the shares by the underwriters is subject to receipt and acceptance and subject to the underwriters’ right to reject any order in whole or in part.

The underwriters have an option to buy up to additional shares of common stock from us to cover sales of shares by the underwriters which exceed the number of shares specified in the table above. The underwriters have 30 days from the date of this prospectus to exercise this option to purchase additional shares. If any shares are purchased with this option to purchase additional shares, the underwriters will purchase shares in approximately the same proportion as shown in the table above. If any additional shares of common stock are purchased, the underwriters will offer the additional shares on the same terms as those on which the shares are being offered.

In connection with this offering, the underwriters may engage in stabilizing transactions, which involves 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 short sales of common stock, which involves the sale by the underwriters 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 short sales. Short sales may be “covered” shorts, which are short positions in an amount not greater than the underwriters’ option to purchase additional shares referred to above, or may be “naked” shorts, which are short positions in excess of that amount. The underwriters may close out any covered short position either by exercising their option to purchase additional shares, in whole or in part, or by purchasing shares in the open market. In making this determination, the underwriters will consider, among other things, the price of shares available for purchase in the open market compared to the price at which the underwriters may purchase shares through the option to purchase additional shares. A naked short position is more likely to be created if the underwriters are 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 underwriters create a naked short position, they will purchase shares in the open market to cover the position.

The underwriters have advised us that, pursuant to Regulation M of the Securities Act of 1933, 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. This means that if the representatives of the underwriters purchase common stock in the open market in stabilizing transactions or to cover short sales, the representatives can require the underwriters that sold those shares as part of this offering to repay the underwriting discount received by them.

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 underwriters commence these activities, they may discontinue them at any time. The underwriters may carry out these transactions on Nasdaq, in the over-the-counter market or otherwise.
