Super Micro Computer, Inc.

% Series A Mandatory Convertible Preferred Stock

We are offering 75,000,000 depositary shares (“Depositary Shares”), each of which represents a 1/20th interest in a share of our % Series A Mandatory Convertible Preferred Stock, par value $0.001 per share (“Mandatory Convertible Preferred Stock”). The shares of Mandatory Convertible Preferred Stock will be deposited with Computershare Trust Company, N.A., as bank depositary, pursuant to a deposit agreement. Holders of the Depositary Shares will be entitled to a proportional fractional interest in the rights and preferences of the Mandatory Convertible Preferred Stock, including conversion, dividend, liquidation and voting rights, subject to the provisions of such deposit agreement.

Dividends on our Mandatory Convertible Preferred Stock will be payable on a cumulative basis when, as and if declared by our board of directors, or an authorized committee of our board of directors, at an annual rate of % on the liquidation preference of $1,000 per share. We may pay declared dividends in cash or, subject to certain limitations, in shares of our common stock, par value $0.001 per share, or in any combination of cash and common stock on March 1, June 1, September 1 and December 1 of each year, commencing on, and including, September 1, 2026 and ending on, and including, June 1, 2029.

Each share of our Mandatory Convertible Preferred Stock has a liquidation preference of $1,000 (and, correspondingly, each Depositary Share represents a liquidation preference of $50). Unless earlier converted, each share of our Mandatory Convertible Preferred Stock will automatically convert on the second business day immediately following the last trading day of the final averaging period (as defined below) into between and shares of our common stock, subject to anti-dilution adjustments. The number of shares of our common stock issuable on conversion will be determined based on the average VWAP (as defined herein) of our common stock over the 20 consecutive trading day period beginning on, and including, the 21st scheduled trading day prior to June 1, 2029, which we refer to herein as the “final averaging period.” At any time prior to June 1, 2029, a holder of 20 Depositary Shares may cause the bank depositary to convert one share of our Mandatory Convertible Preferred Stock, on such holder’s behalf, into a number of shares of our common stock equal to the minimum conversion rate of , subject to anti-dilution adjustments. If a holder of 20 Depositary Shares causes the bank depositary to convert one share of our Mandatory Convertible Preferred Stock, on such holder’s behalf, during a specified period beginning on the effective date of a fundamental change (as described herein), the conversion rate will be adjusted under certain circumstances, and such holder will also be entitled to a make whole dividend amount (as described herein).

Concurrently with this offering and pursuant to a separate prospectus supplement, we are making a public offering of $1.25 billion of shares of our common stock, par value $0.001 per share (“common stock”) (the “Common Stock Offering”). We expect to grant the underwriters of the Common Stock Offering a 30-day option to purchase up to an additional $187.5 million of shares of our common stock, solely to cover sales in excess of the $1.25 billion of firm shares (the “firm shares”). In addition, concurrently with this offering and pursuant to a separate prospectus supplement, we intend to enter into an equity distribution agreement with certain agents under which we may sell up to $2 billion of shares of our common stock in “at-the-market” transactions from time to time (the “ATM Program” and, together with the Common Stock Offering, the “Concurrent Financing Transactions”). The closing of this offering is not conditioned upon the closing of the Common Stock Offering or entry into the ATM Program. Neither the closing of the Common Stock Offering nor entry into the ATM Program is conditioned upon the closing of this offering. We cannot assure you that the Common Stock Offering or the establishment of the ATM Program will be completed on the terms described herein, or at all. Nothing contained herein shall constitute an offer to sell or a solicitation of an offer to buy any of the common stock being offered in the Common Stock Offering or the common stock being offered from time to time in the ATM Program. See the section titled “Description of the Concurrent Financing Transactions.”

We intend to use the net proceeds from this offering, together with the net proceeds from the Concurrent Financing Transactions, if completed, to fund the purchase of components to satisfy the approximately $39 billion of orders that the Company has received in recent weeks for its advanced AI servers, including its Data Center Building Block Solutions, from more than 20 customers, that the Company plans to fulfill in future quarters. The Company may also use a portion of the net proceeds from this offering, together with the net proceeds from the Concurrent Financing Transactions, if completed, for other general corporate purposes, which may include repayment of debt, additions to working capital and capital expenditures.

Prior to this offering, there has been no public market for the Depositary Shares or the Mandatory Convertible Preferred Stock. We intend to apply to list the Depositary Shares on the Nasdaq Global Select Market under the symbol “SMCIP.” Our common stock is listed on the Nasdaq Global Select Market under the symbol “SMCI.”

Investing in Depositary Shares involves risks. See the section titled “Risk Factors” beginning on page 13 of this prospectus supplement and in our Annual Report on Form 10-K for the fiscal year ended June 30, 2025 and our Quarterly Reports on Form 10-Q for the fiscal quarters ended September 30, 2025, December 31, 2025 and March 31, 2026, which are incorporated by reference herein, for a discussion of certain risks that should be considered in connection with an investment in Depositary Shares.

(2)	See the section titled “Underwriting” beginning on page S-78 of this prospectus supplement for a description of the compensation payable to the underwriters.

We expect to grant the underwriters a 30-day option to purchase up to 11,250,000 additional Depositary Shares from us at the public offering price, less the underwriting discount, solely to cover over-allotments.

Neither the Securities and Exchange Commission nor any state securities commission has approved or disapproved of these securities or determined if this prospectus supplement or the accompanying prospectus is truthful or complete. Any representation to the contrary is a criminal offense.

We urge you to carefully read this prospectus supplement and the accompanying prospectus, which describe the terms of the offering, before you make your investment decision.

It is expected that delivery of the Depositary Shares will be made against payment therefor on , 2026 (the “expected settlement date”), which is the second business day following the trade date for the Depositary Shares (such settlement cycle being referred to as “T+2”). Under Rule 15c6-1 under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), trades in the secondary market generally are required to settle in one business day, unless the parties to any such trade expressly agree otherwise. Accordingly, purchasers who wish to trade the Depositary Shares prior to the business day preceding the expected settlement date will be required, by virtue of the fact that the Depositary Shares initially will settle T+2, to specify an alternative settlement cycle at the time of any such trade to prevent a failed settlement. Purchasers of the Depositary Shares who wish to trade the Depositary Shares prior to the business day preceding the expected settlement date should consult their own advisors.

THE OFFERING

The following summary contains basic information about the Depositary Shares and this offering. It does not contain all of the information that may be important to you. For a more complete understanding of this offering, we encourage you to read this entire prospectus supplement and the accompanying prospectus.

Issuer

Super Micro Computer, Inc., a Delaware corporation.

Depositary Shares Offered

75,000,000 Depositary Shares, each of which represents a 1/20th interest in a share of our Mandatory Convertible Preferred Stock. Each Depositary Share entitles the holder of such Depositary Share, through the bank depositary, to a proportional fractional interest in the rights and preferences of such share of Mandatory Convertible Preferred Stock, including conversion, dividend, liquidation and voting rights, subject to the terms of the deposit agreement.

Underwriters’ Option to Purchase Additional Depositary Shares

We expect to grant the underwriters a 30-day option to purchase up to 11,250,000 additional Depositary Shares, at the public offering price, less the underwriting discount, solely to cover over-allotments.

Public Offering Price

$50 per Depositary Share.

Liquidation Preference

$1,000 per share of our Mandatory Convertible Preferred Stock (equivalent to $50 per Depositary Share).

Dividends

% of the liquidation preference of $1,000 per share of our Mandatory Convertible Preferred Stock per annum. Dividends will accumulate from the most recent date as to which dividends shall have been paid or, if no dividends have been paid, from the initial issue date (as defined below) of the Mandatory Convertible Preferred Stock, whether or not in any dividend period or periods there have been funds legally available for the payment of such dividends and, to the extent that we are legally permitted to pay dividends and our board of directors, or an authorized committee thereof, declares a dividend payable with respect to our Mandatory Convertible Preferred Stock, we will pay such dividends in cash or, subject to certain limitations, by delivery of shares of our common stock or through any combination of cash and shares of our common stock, as determined by our board of directors (or an authorized committee thereof) in its sole discretion, on each dividend payment date; provided that any unpaid dividends will continue to accumulate. Dividends that are declared will be payable on the dividend payment dates (as described below) to holders of record of the Mandatory Convertible Preferred Stock on the February 15, May 15, August 15 or November 15, as the case may be, immediately preceding the relevant dividend payment date (each, a “record date”), whether or not such holders convert their Depositary Shares, or such Depositary Shares are automatically converted, after a record date and on or prior to the immediately succeeding dividend payment date. The expected

S-3

dividend payable on the first dividend payment date is approximately $ per share of our Mandatory Convertible Preferred Stock (equivalent to $ per Depositary Share). Each subsequent dividend is expected to be approximately $ per share of our Mandatory Convertible Preferred Stock (equivalent to $ per Depositary Share). See the section titled “Description of Mandatory Convertible Preferred Stock—Dividends.”

If we elect to make any payment of a declared dividend, or any portion thereof, in shares of our common stock, such shares shall be valued for such purpose at the average VWAP (as defined under the section titled “Description of Mandatory Convertible Preferred Stock—Definitions”) per share of our common stock over the five consecutive trading day period ending on, and including, the second trading day immediately preceding the applicable dividend payment date (the “five-day average price”), multiplied by 97%. Notwithstanding the foregoing, in no event will the number of shares of our common stock delivered in connection with any declared dividend exceed a number equal to the amount of such declared dividend as to which we have elected to deliver shares of our common stock in lieu of paying cash divided by $ , which amount represents approximately 35% of the initial price (as defined below), subject to adjustment in a manner inversely proportional to any adjustment to each fixed conversion rate (such dollar amount, as adjusted, the “floor price”). To the extent that the amount of the declared dividend as to which we have elected to deliver shares of our common stock in lieu of paying cash exceeds the product of the number of shares of common stock delivered in connection with such declared dividend and 97% of the five-day average price, we will, if we are legally able to do so, and to the extent permitted under the terms of the documents governing any of our indebtedness, notwithstanding any notice by us to the contrary, pay such excess amount in cash.

The “initial price” equals $1,000, divided by the maximum conversion rate (as defined below), rounded to the nearest $0.0001, and is initially approximately equal to the per share public offering price of our common stock in the Common Stock Offering (or, if the Common Stock Offering does not price, the closing price of our common stock on June , 2026).

Dividend Payment Dates

March 1, June 1, September 1 and December 1 of each year, commencing on, and including, September 1, 2026 and ending on, and including, June 1, 2029. If a dividend payment date is not a business day, payment will be made on the next succeeding business day, without any interest or other payment in lieu of interest accruing with respect to this delay.

No Redemption

We may not redeem the shares of Mandatory Convertible Preferred Stock or the Depositary Shares. However, at our option, we may purchase the Mandatory Convertible Preferred Stock or Depositary Shares from time to time in the open market, by tender offer, exchange offer or otherwise.

S-4

Mandatory Conversion Date

The second business day immediately following the last trading day of the final averaging period (as defined below). The mandatory conversion date is expected to be June 1, 2029.

Mandatory Conversion

On the mandatory conversion date, each outstanding share of our Mandatory Convertible Preferred Stock, unless previously converted, will automatically convert into a number of shares of our common stock equal to the conversion rate as described below, and each Depositary Share will automatically convert into a number of shares of common stock equal to a proportionate fractional interest in such shares of common stock.

If we declare a dividend on the Mandatory Convertible Preferred Stock for the dividend period ending on June 1, 2029, we will pay such dividend to the holders of record as of May 15, 2029, as described above. If, on or prior to May 15, 2029, we have not declared all or any portion of all accumulated and unpaid dividends on the Mandatory Convertible Preferred Stock, the conversion rate will be adjusted so that holders receive an additional number of shares of common stock equal to the amount of such accumulated and unpaid dividends that have not been declared (the “additional conversion amount”), divided by the greater of (i) the floor price and (ii) 97% of the five-day average price (calculated as if the applicable dividend payment date were June 1, 2029). To the extent that the additional conversion amount per share of Mandatory Convertible Preferred Stock exceeds the product of such number of additional shares and 97% of such five-day average price, we will, if we are legally able to do so, and to the extent permitted under the terms of the documents governing any of our indebtedness, declare and pay such excess amount in cash.

Conversion Rate

Upon conversion on the mandatory conversion date, the conversion rate for each share of our Mandatory Convertible Preferred Stock will be not more than shares of common stock and not less than shares of common stock (respectively, the “maximum conversion rate” and the “minimum conversion rate”), depending on the applicable market value of our common stock, as described below and subject to certain anti-dilution adjustments. Correspondingly, the conversion rate per Depositary Share will be not more than shares of common stock and not less than shares of common stock

The “applicable market value” of our common stock is the average VWAP per share of our common stock over the final averaging period. The “final averaging period” is the 20 consecutive trading day period beginning on, and including, the 21st scheduled trading day immediately preceding June 1, 2029. The conversion rate will be calculated as described under the section titled “Description of Mandatory Convertible Preferred Stock—Mandatory Conversion.”

S-5

The following table illustrates the conversion rate per share of our Mandatory Convertible Preferred Stock, subject to certain anti-dilution adjustments.

The following table illustrates the conversion rate per Depositary Share, subject to certain anti-dilution adjustments:

The “threshold appreciation price” equals $1,000, divided by the minimum conversion rate, rounded to the nearest $0.0001, which initially is $ , and represents an approximately % appreciation over the initial price.

Conversion at the Option of the Holder

Other than during a fundamental change conversion period (as defined below), at any time prior to June 1, 2029, a holder of Mandatory Convertible Preferred Stock may elect to convert such holder’s shares of our Mandatory Convertible Preferred Stock, in whole or in part, at the minimum conversion rate of shares of common stock per share of Mandatory Convertible Preferred Stock (equivalent to shares of common stock per Depositary Share) as described under the section titled “Description of Mandatory Convertible Preferred Stock—Conversion at the Option of the Holder.” This minimum conversion rate is subject to certain anti-dilution and other adjustments. Because each Depositary Share represents a 1/20th fractional interest in a share of our Mandatory Convertible Preferred Stock, a holder of Depositary Shares may convert its Depositary Shares only in lots of 20 Depositary Shares.

S-6

If, as of the effective date of any early conversion (the “early conversion date”), we have not declared all or any portion of the accumulated and unpaid dividends for all full dividend periods ending on or prior to the dividend payment date immediately preceding such early conversion date, the conversion rate for such early conversion will be adjusted so that converting holders receive an additional number of shares of common stock equal to such amount of accumulated and unpaid dividends that have not been declared for such full dividend periods (the “early conversion additional amount”), divided by the greater of (i) the floor price and (ii) the average VWAP per share of our common stock over the 20 consecutive trading day period ending on, and including, the second trading day immediately preceding the early conversion date (the “early conversion average price”). Notwithstanding the last sentence under “Description of Mandatory Convertible Preferred Stock—Method of Payment of Dividends” below, to the extent that the early conversion additional amount exceeds the product of such number of additional shares and the early conversion average price, we will not have any obligation to pay the shortfall in cash.

Conversion at the Option of the Holder Upon a Fundamental Change; Fundamental Change Dividend Make-Whole Amount

If a “fundamental change” (as defined under the section titled “Description of Mandatory Convertible Preferred Stock—Conversion at the Option of the Holder upon Fundamental Change; Fundamental Change Dividend Make-Whole Amount”) occurs on or prior to June 1, 2029, holders of the Mandatory Convertible Preferred Stock will have the right to convert their shares of Mandatory Convertible Preferred Stock, in whole or in part, into shares of common stock at the “fundamental change conversion rate” during the period beginning on, and including, the effective date of such fundamental change and ending on, and including, the earlier of (a) the date that is 20 calendar days after such effective date (or, if later, the date that is 20 calendar days after holders receive notice of such fundamental change) and (b) June 1, 2029. For the avoidance of doubt, the period described in the immediately preceding sentence may not end on a date that is later than June 1, 2029. The fundamental change conversion rate will be determined based on the effective date of the fundamental change and the price paid (or deemed paid) per share of our common stock in such fundamental change. Holders who convert shares of our Mandatory Convertible Preferred Stock during that period will also receive (1) a “fundamental change dividend make-whole amount” equal to the present value (calculated using a discount rate of % per annum) of all scheduled dividend payments on such shares (excluding any accumulated and unpaid dividends for any dividend period prior to the effective date of the fundamental change, including for the partial dividend period, if any, from, and including, the dividend payment date immediately preceding the effective date to, but excluding, the effective date (collectively, the “accumulated

S-7

dividend amount”)) for all the remaining full dividend periods and for the partial dividend period from, and including, the effective date to, but excluding, the next dividend payment date, and (2) to the extent that there is any accumulated dividend amount, the accumulated dividend amount (clauses (1) and (2), together, the “make-whole dividend amount”), in the case of clauses (1) and (2), subject to our right to deliver shares of our common stock in lieu of all or part of such make-whole dividend amount; provided that if the effective date or the conversion date falls after the record date for a declared dividend and prior to the next dividend payment date, such dividend will be paid on such dividend payment date to the holders as of such record date, such dividend will not be included in the accumulated dividend amount, and the fundamental change dividend make-whole amount will not include the present value of the payment of such dividend. Because each Depositary Share represents a 1/20th fractional interest in a share of our Mandatory Convertible Preferred Stock, a holder of Depositary Shares may convert its Depositary Shares upon a fundamental change only in lots of 20 Depositary Shares.

If we elect to make any payment of the make-whole dividend amount, or any portion thereof, in shares of our common stock, such shares shall be valued for such purpose at 97% of the price paid (or deemed paid) per share of our common stock in the fundamental change. Notwithstanding the foregoing, in no event will the number of shares of our common stock that we deliver in lieu of paying all or a portion of the make-whole dividend amount in cash exceed a number equal to the portion of the make-whole dividend amount to be paid by the delivery of common stock divided by the greater of (i) the floor price and (ii) 97% of the price paid (or deemed paid) per share of our common stock in the fundamental change. To the extent that the portion of the make-whole dividend amount as to which we have elected to deliver shares of common stock in lieu of paying cash exceeds the product of the number of shares of common stock delivered in respect of such portion of the make-whole dividend amount and 97% of the price paid (or deemed paid) per share of our common stock in the fundamental change, we will, if we are legally able to do so, and to the extent permitted under the terms of the documents governing any of our indebtedness, notwithstanding any notice by us to the contrary, pay such excess amount in cash.

In addition, if we are prohibited from paying or delivering, as the case may be, the make-whole dividend amount (whether in cash or in shares of our common stock), in whole or in part, due to limitations of applicable Delaware law, the conversion rate will instead be increased by a number of shares of common stock equal to the cash amount of the aggregate unpaid and undelivered make-whole dividend amount, divided by the greater of (i) the floor price and (ii) 97% of the price paid (or deemed paid) per share of our common stock in the fundamental change. To the extent that the cash amount of the

S-8

aggregate unpaid and undelivered make-whole dividend amount exceeds the product of such number of additional shares and 97% of the price paid (or deemed paid) per share of our common stock in the fundamental change, we will not have any obligation to pay the shortfall in cash.

See the section titled “Description of Mandatory Convertible Preferred Stock—Conversion at the Option of the Holder upon Fundamental Change; Fundamental Change Dividend Make-Whole Amount.”

Anti-dilution Adjustments

The conversion rate may be adjusted in the event of, among other things: (1) stock dividends or distributions; (2) certain distributions to holders of our common stock of rights or warrants to purchase our common stock; (3) subdivisions or combinations of our common stock; (4) certain distributions to holders of our common stock of evidences of our indebtedness, shares of capital stock, securities, rights to acquire our capital stock, cash or other assets, including by spin-off; (5) certain distributions to holders of our common stock of cash; and (6) certain tender or exchange offers by us or one of our subsidiaries for our common stock, in each case subject to certain exceptions. See the section titled “Description of Mandatory Convertible Preferred Stock—Anti-Dilution Adjustments.”

Voting Rights

Except as specifically required by Delaware law or our Amended and Restated Certificate of Incorporation, which will include the certificate of designations for the Mandatory Convertible Preferred Stock, the holders of Mandatory Convertible Preferred Stock will have no voting rights.

Whenever dividends on shares of Mandatory Convertible Preferred Stock have not been declared and paid for six or more dividend periods (including, for the avoidance of doubt, the dividend period beginning on, and including, the initial issue date and ending on, but excluding, September 1, 2026), whether or not consecutive, the authorized number of directors on our board of directors will, at the next annual meeting of stockholders or at a special meeting of stockholders as provided below, be increased by two (or we will vacate the offices of two directors) and the holders of the Mandatory Convertible Preferred Stock, voting together as a single class with holders of all other preferred stock of equal rank having similar voting rights then outstanding, will be entitled at our next special or annual meeting of stockholders to vote for the election of a total of two additional members of our board of directors, subject to certain limitations.

We will not, without the affirmative vote or consent of holders of at least two-thirds of the outstanding shares of Mandatory Convertible Preferred Stock, (1) authorize or create, or increase the authorized amount of, any senior stock (as defined below); (2) amend, alter or repeal the provisions of our Amended and Restated Certificate of Incorporation so as to materially and adversely affect the special

S-9

rights, preferences, privileges or voting powers of the Mandatory Convertible Preferred Stock; or (3) consummate a binding share exchange or reclassification involving shares of Mandatory Convertible Preferred Stock or a merger or consolidation of us with another entity unless the Mandatory Convertible Preferred Stock remains outstanding or is replaced by preference securities with terms no less favorable to holders in any material respect, in each case, subject to certain exceptions.

See the section titled “Description of Mandatory Convertible Preferred Stock—Voting Rights” and “Description of Depositary Shares—Voting the Mandatory Convertible Preferred Stock.”

Ranking

The Mandatory Convertible Preferred Stock will rank with respect to dividend rights and/or distribution rights upon our liquidation, winding-up or dissolution, as applicable:

•

senior to (i) our common stock and (ii) each other class or series of capital stock established after the first original issue date of shares of the Mandatory Convertible Preferred Stock (which we refer to as the “initial issue date”) the terms of which do not expressly provide that such capital stock ranks either (x) senior to the Mandatory Convertible Preferred Stock as to dividend rights or distribution rights upon our liquidation, winding-up or dissolution or (y) on parity with the Mandatory Convertible Preferred Stock as to dividend rights and distribution rights upon our liquidation, winding-up or dissolution (which we refer to collectively as “junior stock”);

•

on parity with any class or series of capital stock established after the initial issue date the terms of which expressly provide that such capital stock will rank on parity with the Mandatory Convertible Preferred Stock as to dividend rights and distribution rights upon our liquidation, winding-up or dissolution (which we refer to collectively as “parity stock”);

•

junior to each class or series of capital stock established after the initial issue date the terms of which expressly provide that such capital stock will rank senior to the Mandatory Convertible Preferred Stock as to dividend rights or distribution rights upon our liquidation, winding-up or dissolution (which we refer to collectively as “senior stock”); and

•

junior to our existing and future indebtedness and other liabilities (other than intercompany obligations).

In addition, the Mandatory Convertible Preferred Stock, with respect to dividend rights and distribution rights upon our liquidation, winding-up or dissolution, will be structurally subordinated to existing and future indebtedness and other liabilities of our subsidiaries as well as the capital stock of our subsidiaries held by third parties.

S-10

As of March 31, 2026, excluding intercompany indebtedness, we had approximately $8.8 billion of consolidated indebtedness for borrowed money outstanding.

RISK FACTORS

An investment in the Depositary Shares is subject to risks and uncertainties. This prospectus supplement does not describe all of the risks of an investment in the Depositary Shares. You should consult your own financial and legal advisors about the risks entailed by an investment in the Depositary Shares and the suitability of an investment in the Depositary Shares in light of your particular circumstances. For a discussion of the factors you should carefully consider before deciding to purchase any Depositary Shares that may be offered, please read “Risk Factors” in Part I, Item 1A of our Annual Report on Form 10-K for the year ended June 30, 2025 and Quarterly Report on Form 10-Q for the quarter ended March 31, 2026, as well as those risk factors included below. Additional risks and uncertainties not currently known to us or that we currently deem immaterial may also adversely affect our business and operations. If any of the matters described in the risk factors were to occur, our business, financial condition, results of operations, cash flows or prospects could be materially adversely affected. In such case, you could lose all or a portion of your investment.

Risks Related to Our Business and Operations

We operate in a rapidly changing economic and technological environment that presents numerous risks, many of which are driven by factors that we cannot control or predict. The risk factors set forth in our Annual Report on Form 10-K for the fiscal year ended June 30, 2025 and our Quarterly Reports on Form 10-Q for the fiscal quarters ended September 30, 2025, December 31, 2025 and March 31, 2026, which are incorporated by reference into this prospectus supplement and the accompanying prospectus, highlight some of these risks. You should read our Annual Report on Form 10-K for the fiscal year ended June 30, 2025, including the section “Risk Factors,” as well as our Quarterly Reports on Form 10-Q for the fiscal quarters ended September 30, 2025, December 31, 2025 and March 31, 2026, which are incorporated by reference into this prospectus supplement and the accompanying prospectus.

Conflicts of interest may arise with Ablecom and Compuware, and they may adversely affect our operations.

We use Ablecom, a related party, for contract design and manufacturing coordination support and warehousing, and Compuware, also a related party and an affiliate of Ablecom, for distribution, contract manufacturing and warehousing. We work with Ablecom to optimize modular designs for our chassis and certain other components. We outsource to Compuware a portion of our design activities and a significant part of our manufacturing of subassemblies, particularly power supplies. Our purchases of products from Ablecom and Compuware represented 3.3%, 4.3%, and 6.6% of our cost of sales for fiscal years 2025, 2024, and 2023, respectively. Ablecom and Compuware’s sales to us constitute a majority of Ablecom’s and Compuware’s net sales. Ablecom and Compuware are both privately held Taiwan-based companies. In addition, we have appointed Compuware as a nonexclusive authorized distributor of our products in Taiwan, China and Australia, in addition to acting as our sales representative on certain transactions in Asia. Each of Ablecom and Compuware are also developing campuses in close proximity to the campus we developed in Malaysia to expand our manufacturing.

Steve Liang, Ablecom’s Chief Executive Officer and largest shareholder, is the brother of Charles Liang, our President, Chief Executive Officer and Chairman of our Board of Directors (the “Board”). Steve Liang owned no shares of our common stock as of June 30, 2025, 2024, or 2023. Charles Liang and his spouse, Sara Liu, our Co-Founder, Senior Vice President and Director, jointly owned approximately 10.5% of Ablecom’s capital stock, while Mr. Steve Liang and his family members owned approximately 35.0% of Ablecom’s outstanding common stock as of June 30, 2025. Steve Liang is also a member of Compuware’s Board of Directors and is an equity holder of Compuware. Neither Charles Liang nor Sara Liu own any shares of Compuware. In addition, neither Charles Liang nor Sara Liu serve on the board of directors of either Ablecom or Compuware.

Bill Liang, a brother of both Charles Liang and Steve Liang, is also a member of the Board of Directors of Ablecom. In addition, Bill Liang is the Chief Executive Officer of Compuware, Chairman of Compuware’s Board of Directors and a holder of equity interest in Compuware.

S-13

Charles Liang and Sara Liu are both significant stockholders of the Company, and have considerable influence over the management of our business relationships. Accordingly, we may be disadvantaged by the economic interests of Mr. Charles Liang and his spouse, Ms. Sara Liu, as stockholders of Ablecom and Mr. Charles Liang’s personal relationship with Ablecom’s Chief Executive Officer and Compuware’s Chief Executive Officer.

In addition, a sibling of Yih-Shyan (Wally) Liaw, formerly our Senior Vice President, Business Development and a director on our Board, owns approximately 11.7% of Ablecom’s capital stock and 8.7% of Compuware’s capital stock.

In October 2018, our Chief Executive Officer, Charles Liang, personally borrowed approximately $12.9 million from Chien-Tsun Chang, the spouse of Steve Liang. The loan was unsecured, had no maturity date and bore interest at 0.8% per month for the first six months, increased to 0.85% per month through February 28, 2020, and reduced to 0.25% effective March 1, 2020. The loan was originally made at Mr. Liang’s request to provide funds to repay margin loans from two financial institutions that were secured by shares of our common stock he held. The lenders called the loans in October 2018, following the suspension of our common stock from trading on Nasdaq in August 2018 and the subsequent decline in its market price that October. As of June 30, 2025, the amount due on the unsecured loan (including principal and accrued interest) was approximately $16.8 million.

In October 2023, Ablecom and Compuware acquired an approximate 30% interest in Leadtek, a Taiwan company specializing in providing professional graphics cards and workstation solutions. At the time of the Leadtek Investment (as defined herein), Leadtek was, and continues to be, an authorized reseller for us. While prior to the Leadtek Investment none of our related persons had direct or indirect material interests in any transactions with Leadtek, following the closing of the Leadtek Investment, Steve Liang and Bill Liang have served as two of the seven members of the Leadtek’s board of directors.

We may not negotiate or enforce contractual terms as aggressively with Ablecom or Compuware as we might with an unrelated party, and the commercial terms of our agreements may be less favorable than we might obtain in negotiations with third parties. If our business dealings with Ablecom or Compuware are not as favorable to us as arms-length transactions, our results of operations may be harmed.

If Ablecom or Compuware are acquired or sold, new ownership could reassess the business and strategy of Ablecom or Compuware, which may disrupt our supply chain or alter the terms and conditions of our agreements. Such changes could negatively impact our operations or increase our costs, thereby adversely affecting our margins and the results of operations.

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.

Negative publicity about us or our products, even if inaccurate or untrue, could adversely affect our reputation and confidence in our products, which could harm our business and operating results. For example, on August 27, 2024, a news article was published by a short seller alleging evidence of accounting manipulation, sibling self-dealing and sanctions evasion (the “Report”). We indicated that such Report contained false or inaccurate statements about us, including misleading presentations of information we previously shared publicly and announced the results of the related Special Committee investigation.

On March 19, 2026, the U.S. Attorney’s Office for the Southern District of New York unsealed an indictment of three individuals either employed or associated with the Company at the time, including Yih-Shyan (Wally) Liaw, our former Senior Vice President, Business Development and a director on our Board, in connection with an alleged conspiracy to commit export control violations (the “Indictment”). Although the Company is not named as a defendant or alleged to be a co-conspirator in the Indictment, has been cooperating with the government’s investigation, and the three individuals are no longer employed or associated with the Company, the Indictment, as well as the prior publication of the Report and our previous Delinquent Reports have all

S-14

contributed to significant volatility in, and declines of, the trading price of our common stock, as well as harm to our reputation, and could continue to do so in the future. Harm to our reputation has in the past, and may in the future, arise from many other sources, including employee misconduct, such as in connection with the alleged conduct described in the Indictment involving individuals associated with the Company at the time, and misconduct by our partners, consultants and outsourced service providers. Additionally, negative publicity with respect to our partners or service providers could also affect our business and operating results to the extent that we rely on these partners or if our customers or prospective customers associate us with these partners.

Harm to our reputation has in the past, and may in the future, arise from many other sources, including employee misconduct, such as in connection with the alleged conduct described in the Indictment involving individuals associated with the Company at the time, and misconduct by our partners, consultants and outsourced service providers. Additionally, negative publicity with respect to our partners or service providers could also affect our business and operating results to the extent that we rely on these partners or if our customers or prospective customers associate us with these partners.

We have been, are currently, and may in the future be subject to various lawsuits and other legal proceedings, disputes, claims, and government inquiries and investigations, which could cause us to incur substantial costs or require us to change our business practices in a way that could seriously harm our business, and any orders, actions or rulings not in our favor could have a material adverse effect on our business, results of operations, and financial condition.

We have been, are currently, and may in the future be subject to various lawsuits, stockholder derivative actions, class action lawsuits, individual or mass arbitration proceedings, and other types of legal proceedings, as well as other disputes, claims, and regulatory or governmental inquiries and investigations, including with regard to contract or commercial disputes, consumer protection, privacy, data protection, intellectual property, tax, employment, and corporate governance, among other matters. In addition, the circumstances underlying the matters discussed in Item 9. “Changes in and Disagreements with Accountants on Accounting and Financial Disclosure” of our Annual Report on Form 10-K for the fiscal year ended June 30, 2025 continue to create the risk of additional litigation and claims by investors and examinations, investigations, proceedings and orders by regulatory authorities. These include a broad range of potential actions that may be taken against us by the SEC or other regulatory agencies, including a cease-and-desist order and/or the assessment of possible civil monetary penalties. For example, the Company received a subpoena from the SEC requesting the production of documents relating to certain customers, including one customer that is the subject of the allegations in the Indictment, and the Company’s controls and procedures. We are cooperating with the SEC’s requests, but we cannot predict the scope, duration, or outcome of this matter, and the SEC may issue additional subpoenas or other information requests.

The Company also received a grand jury subpoena from the U.S. Attorney’s Office for the Southern District of New York seeking documents and information relating to the individuals and facts referenced in the Indictment, as well as the Company’s compliance program and internal controls, and related issues. The Company has also received other subpoenas, including one from the U.S. Attorney’s Offices for the Eastern District of New York and one from Central District of California that predate the Indictment requesting documents and information relating to certain other customers. The Company has not been informed that it is the target of any of these investigations, but if we become the target of any of these investigations, the Department of Justice could pursue civil or criminal enforcement actions against us, seek monetary or other penalties from us (including disgorgement), or require changes to our compliance program and internal controls.

Further, in connection with the Indictment, the Company has initiated an internal review, led by independent members of the Board of Directors, into whether and to what extent enhancements to the Company’s compliance program, internal controls and related policies and procedures may be appropriate. This internal review remains ongoing and is not yet concluded, and, as a result, the Company cannot predict whether the internal review will identify material deficiencies.

S-15

If we fail to meet our contractual commitments or otherwise fail to comply with our contractual obligations, then we could be subject to breach of contract or other claims. Any claims, proceedings, individual or mass arbitration demands, or inquiries or investigations initiated by or against us, whether successful or not, may be time-consuming, subject us to damage awards, regulatory orders, consent decrees, injunctive relief, fines, or other penalties or sanctions, require us to change our policies or practices, result in increased operating costs, divert management’s attention, harm our reputation, and require us to incur significant legal fees, other litigation costs and settlement costs, as well as other expenses. In addition, our insurance may not be adequate to protect us from all material expenses related to pending and future claims. Any of these factors could materially and adversely affect our business, financial condition, and results of operations.

Our operations are impacted by complex laws, rules and regulations related to import and export controls to which our business is subject, and rapid changes in such laws, rules, and regulations as well as political and other actions related thereto may adversely impact our business.

We are subject to U.S. and other applicable trade control regulations that restrict with whom we may transact business, including economic sanctions administered and enforced by the U.S. Treasury Department’s Office of Foreign Assets Control and the import and export controls enforced by the U.S. Commerce Department’s Bureau of Industry and Security (“BIS”), among other U.S. government agencies. If we fail to comply with applicable sanctions, export control or import laws and regulations, we may be subject to civil or criminal penalties. Additionally, any violations could have a material adverse impact on our ability to sell our products to United States federal, state and local government and related entities. For example, we have received multiple subpoenas from the Office of Export Enforcement (“OEE”) of BIS (the “BIS Inquiries”), including at least two subpoenas and one informal request relating to a certain customer implicated by the facts and circumstances that are also the subject of the Indictment. The BIS Inquiries seek documents relating to our business, customers, products, transactions and export compliance practices. We cannot predict the scope, duration or outcome of the BIS Inquiries, and additional subpoenas, civil investigative demands or other requests may be issued. Although we are fully cooperating with these inquiries, and although we have not been informed that we are the target of any of these inquiries, it is possible that these matters could result in significant penalties, fines or other material consequences, including criminal charges. In connection with the BIS Inquiries, BIS could seek to suspend, revoke or deny our export privileges, including through a temporary or permanent denial order that would restrict or prohibit us from participating in transactions subject to the Export Administration Regulations. Even absent a formal enforcement action, the BIS Inquiries may require substantial legal, consulting and compliance expenditures, divert management attention, impair our relationships with customers, suppliers, channel partners and government counterparties, damage our reputation, and adversely affect our ability to raise capital or complete strategic transactions. Any of these outcomes could materially and adversely affect our business, financial condition, results of operations, cash flows and the trading price of our securities.

We have business relationships with companies in China, in Eastern Europe, and elsewhere who have been, or may in the future be, added to a restricted party list. We take steps to minimize business disruption when these situations arise; however, we may be required to terminate or modify such relationships if our activities are prohibited by U.S. or other applicable laws. Further, our association with these parties could subject us to greater scrutiny or reputational harm among current or prospective customers, partners, suppliers, investors, other parties doing business with us or using our products, government enforcement agencies, or the general public. The United States and other countries continually update their lists of import and export-controlled items and technologies, and may impose new or more-restrictive import, export, or sanctions requirements on our products in the future. As a result of regulatory changes, we may be required to obtain licenses or other authorizations to continue supporting existing customers or to supply existing products to new customers in China, Eastern Europe and elsewhere. Further escalations in trade restrictions or hostilities, particularly between the United States and China, could impede our ability to sell or support our products. Although we historically sold products into Russia before broad sanctions were imposed, we no longer sell products or provide services to Russia. We had last recorded revenue from customers based in Russia in February 2022.

S-16

Moreover, the increasing focus on the risks and strategic importance of AI technologies has resulted in regulatory restrictions that target products and services capable of enabling or facilitating AI and may in the future result in additional restrictions impacting some or all of our product and service offerings.

Concerns regarding third-party use of AI for purposes contrary to governmental interests, including concerns relating to the misuse of AI applications, models, and solutions, has resulted in and could in the future result in unilateral or multilateral restrictions on products that can be used for training, modifying, tuning, and deploying large language models (“LLMs”). Such restrictions have limited and could in the future limit the ability of downstream customers and users worldwide to acquire, deploy and use systems that include our products, software, and services, and negatively impact our business and financial results.

Such restrictions could include additional unilateral or multilateral import and export controls on certain products or technology, including but not limited to AI technologies and high-performance computing. As geopolitical tensions have increased, products containing semiconductors associated with AI, including GPUs and associated products, are increasingly the focus of export control restrictions proposed by stakeholders in the U.S. and its allies. The United States has imposed unilateral controls restricting GPUs and associated products, and it is likely that additional unilateral or multilateral controls will be adopted. Such controls have been and may again be very broad in scope and application, prohibit us from exporting our products to any or all customers in one or more markets, including but not limited to China, and could tangentially negatively impact our warehousing locations and options, or could impose other conditions that limit our ability to serve demand abroad and could negatively and materially impact our business, revenue and financial results. Violations or alleged violations of such unilateral controls restricting GPUs and associated products, such as in connection with the alleged conduct described in the Indictment involving individuals associated with the Company at the time, have contributed to significant volatility in, and declines of, the trading price of our common stock, as well as harm to our reputation.

Import and export controls targeting products containing GPUs and semiconductors associated with AI, which have been imposed and are increasingly likely to be further tightened, would further restrict our ability to export our technology, products, or services given that competitors may not be subject to similar restrictions, creating a competitive disadvantage for us and negatively impacting our business and financial results. In addition, such controls may subject downstream users to additional restrictions on the use, resale, repair, or transfer of our products, negatively impacting our business and financial results. Controls could negatively impact our cost and/or ability to provide services.

Import and export controls could disrupt our supply chain and distribution channels, negatively impacting our ability to serve demand, including in markets outside China. Repeated changes in the export control rules are likely to impose compliance burdens on our business and our customers, negatively and materially impacting our business.

Increasing use of economic sanctions and import and export controls has impacted and may in the future impact demand for our products or services, negatively impacting our business and financial results. Reduced demand due to import and export controls could also lead to excess inventory or cause us to incur related supply charges. Additional unilateral or multilateral controls are also likely to include deemed export control limitations that may also have negative impacts. Additional export restrictions may not only impact our ability to serve overseas markets, but also provoke responses from foreign governments, including China, that negatively impact our supply chain or our ability to provide our products and services to customers in all markets worldwide, which could also substantially reduce our revenue.

In October 2022, U.S. export restrictions and export licensing requirements were imposed targeting China’s semiconductor and supercomputing industries. These restrictions impact exports of software, hardware, equipment and technology used to develop, produce or manufacture certain chips in China (including Hong Kong). At the same time, export restrictions and export license requirements were also imposed on certain GPUs and advanced integrated circuits, as well as computing equipment containing such components, with a focus on

S-17

China (including Hong Kong). These restrictions impacted certain of our products, including products that contain the NVIDIA A100 and H100 integrated circuits, among others.

In November 2023, the export control restrictions on advanced integrated circuits, supercomputing and other end uses were revised and further expanded to cover additional countries where we sell our products, including in the Middle East, and additional parties based on the location of their headquarters, or the headquarters of their ultimate parent. Compliance with ever-changing regulations is complex and time consuming. We may experience delays in implementing procedures to address the changing regulatory requirements.

In January 2025, the U.S. export control regulations targeting advanced integrated circuits and computing were further revised to include a worldwide authorization requirement for certain of our advanced computing products. New license exceptions were added to the regulations and allow us to export in some cases without the need for an export license, thus expanding upon previous authorizations. However, these new regulations will, depending on the country and ultimate consignee, also place new limits on the number of advanced computing products that we can export to each ultimate consignee per calendar year, and the number of advanced computing products that the Commerce Department will license per-country over a given period to all exporters in the aggregate. These new limitations create a competitive process for obtaining the product allocation associated with these new government authorizations and therefore could disadvantage us against certain of our competitors. The limitations could also prevent us from selling our advanced computing products to the full extent of customer demand in certain countries that have not historically been subject to these limitations.

In some cases, we rely on channel partners and third parties to distribute and resell our products globally. If channel partners, or their customers, do not adhere to the applicable trade compliance requirements, this can subject us to greater scrutiny or reputational harm among current or prospective customers, partners, suppliers, investors, other parties doing business with us or using our products, government enforcement agencies, or the general public.

In the event import and export controls require us to transition some operations out of certain geographies, such transitions could be costly and time consuming, and adversely affect our operations during any such transition period. To the extent that customer requires products covered by the licensing requirements, we may seek a license for the customer. However, the licensing process is time-consuming. We have no assurance that any such license will be granted or that the license application will be acted upon in a timely manner or at all. Even if a license is offered, it may impose burdensome conditions that we or our customer or end users cannot or decide not to accept.

The process to obtain licenses required under recently adopted export control regulations is complicated and time consuming in the event we determine to pursue them, and there are no assurances they may be granted at all. Our competitive position and future results may be harmed, over the long-term, if there are further changes in import and export controls, including further expansion of the geographic, customer, end use, deemed export, or product scope of the controls, if customers purchase product from competitors, if customers develop their own internal solution, if we are unable to provide contractual warranty or other extended service obligations, if licenses are not granted in a timely manner or denied to significant customers or if we incur significant transition costs. Even if requested licenses are granted, the licenses may be temporary or impose burdensome conditions that we or our customers or end users cannot or choose not to fulfill. The licensing requirements may benefit certain of our competitors, as the licensing process will make our technical support efforts more cumbersome and less certain and encourage customers to pursue alternatives to our products.

Given the increasing strategic importance of AI and rising geopolitical tensions, the export control rules may change again at any time and further subject a wider range of our products to export restrictions and licensing requirements, negatively impacting our business and financial results. In the event of such change, we may be unable to sell our inventory of such products and may be unable to develop replacement products not subject to the licensing requirements, effectively excluding us from markets subject to such restrictions, as well as other

S-18

impacted markets. Any new control that impacts a wider range of our products would likely have a disproportionate impact on us and may disadvantage us against certain of our competitors that sell products that are outside the scope of such control.

Finally, our business depends on our ability to receive consistent and reliable supplies from our overseas partners, especially in Taiwan. Any new restrictions that negatively impact our ability to receive supply of components, parts, or services from Taiwan, would negatively impact our business and financial results.

Although we attempt to ensure that we, our customers, suppliers, resellers, and partners comply with the applicable import, export, and sanctions laws, we cannot guarantee full compliance by all. Actions of our customers, suppliers, resellers and partners are not within our complete control, and our products could be re-exported to sanctioned persons or countries or provided by our retailers to third persons in contravention of our requirements or instructions or the laws. In addition, there are inherent limitations to the effectiveness of any policies, procedures, and internal controls relating to such compliance, and there can be no assurance that such procedures or internal controls will work effectively at all times or protect us against liability under anti-corruption, sanctions or other laws for actions taken by us, our resellers or partners. For example, the Indictment alleged that the three individuals employed or associated with the Company at the time worked closely with third-party brokers with customers based in China to commit export-control violations. Any such potential violation by us, our customers, suppliers, resellers, or our partners could have negative consequences, including government inquiries, investigations, enforcement actions, monetary fines, or civil and/or criminal penalties, and our reputation, brand, and revenue may be harmed.

Risks Related to this Offering and Ownership of the Depositary Shares and the Mandatory Convertible Preferred Stock

You are making an investment decision in the Depositary Shares as well as in our Mandatory Convertible Preferred Stock.

As described in this prospectus supplement, you are investing in Depositary Shares that represent fractional interests in our Mandatory Convertible Preferred Stock. The bank depositary will rely solely on the dividend payments and other distributions on the Mandatory Convertible Preferred Stock it receives from us to fund all dividend payments and other distributions on the Depositary Shares.

You will bear the risk of a decline in the market price of our common stock between the pricing date for the Depositary Shares and the mandatory conversion date.

The number of shares of our common stock that you would receive upon mandatory conversion of our Mandatory Convertible Preferred Stock (and the related conversion of the Depositary Shares) is not fixed, but instead will depend on the applicable market value of our common stock, which is the average VWAP per share of our common stock over the final averaging period, which is the 20 consecutive trading day period beginning on, and including, the 21st scheduled trading day immediately preceding June 1, 2029. The aggregate market value of the shares of our common stock that you would receive upon mandatory conversion may be less than the aggregate liquidation preference of the Mandatory Convertible Preferred Stock represented by your Depositary Shares. Specifically, if the applicable market value of our common stock is less than the initial price, which is calculated by dividing $1,000 by the maximum conversion rate and will initially equal approximately the per share public offering price of our common stock in the Common Stock Offering (or, if the Common Stock Offering does not price, the closing price of our common stock on June , 2026), subject to certain anti-dilution adjustments, the market value of the shares of our common stock that you would receive upon mandatory conversion of each share of Mandatory Convertible Preferred Stock will be less than the $1,000 liquidation preference per share of Mandatory Convertible Preferred Stock (and, accordingly the market value of shares of our common stock that you would receive upon mandatory conversion of each Depositary Share will be less than the $50 liquidation preference per Depositary Share), and an investment in the Depositary Shares would result in a loss, without taking into consideration the payment of dividends. Accordingly, you will bear the entire risk of a decline in the market price of our common stock. Any such decline could be substantial.

S-19

In addition, because the number of shares delivered to you upon mandatory conversion will be based upon the applicable market value, which is the average VWAP per share of our common stock over the final averaging period, the shares of common stock you receive upon mandatory conversion may be worth less than the shares of common stock you would have received had the applicable market value been equal to the VWAP per share of our common stock on the mandatory conversion date or the average VWAP of our common stock over a different period of days.

Purchasers of the Depositary Shares may not realize any or all of the benefit of an increase in the market price of shares of our common stock.

The aggregate market value of the shares of our common stock that you will receive upon mandatory conversion of each share of our Mandatory Convertible Preferred Stock (and the related conversion of the Depositary Shares) on the mandatory conversion date will only exceed the liquidation preference of $1,000 per share of Mandatory Convertible Preferred Stock (and the liquidation preference of $50 per Depositary Share) if the applicable market value of our common stock exceeds the threshold appreciation price, which is calculated by dividing $1,000 by the minimum conversion rate and initially equals approximately $ , subject to certain anti-dilution adjustments. The threshold appreciation price represents an appreciation of approximately % over the initial price. If the applicable market value of our common stock exceeds the threshold appreciation price, you will receive on the mandatory conversion date approximately % (which percentage is approximately equal to the initial price divided by the threshold appreciation price) of the value of our common stock that you would have received if you had made a direct investment in our common stock (in the Common Stock Offering or at the last reported sale price per share) on the date of this prospectus supplement. This means that the opportunity for equity appreciation provided by an investment in the Depositary Shares (and the underlying Mandatory Convertible Preferred Stock) is less than that provided by a direct investment in shares of our common stock.

In addition, if the market value of our common stock appreciates and the applicable market value of our common stock is equal to or greater than the initial price but less than or equal to the threshold appreciation price, the aggregate market value of the shares of our common stock that you would receive upon mandatory conversion will only be equal to the aggregate liquidation preference of the Mandatory Convertible Preferred Stock (and, correspondingly, the aggregate market value of our common stock that you would receive upon the related mandatory conversion of the Depositary Shares will only be equal to the aggregate liquidation preference of the Depositary Shares), and you will realize no equity appreciation on our common stock.

The market price of our common stock, which may fluctuate significantly, will directly affect the market price for the Depositary Shares.

We expect that, generally, the market price of our common stock will affect the market price of the Depositary Shares more than any other single factor. This may result in greater volatility in the market price of the Depositary Shares than would be expected for nonconvertible preferred stock or depositary shares representing nonconvertible preferred stock. The market price of our common stock has fluctuated significantly and could continue to fluctuate significantly in response to a number of factors, including changing laws and regulations that may impact our business, our ability to obtain financing on satisfactory terms, changes in recommendations by financial analysts as well as economic, financial, political and other factors, many of which are beyond our control. For more information regarding such factors, see the section titled “—Risks Related to Ownership of our Common Stock” and “Risk Factors” in our Annual Report on Form 10-K for the fiscal year ended June 30, 2025 and in our Quarterly Report on Form 10-Q for the fiscal quarter ended March 31, 2026.

In addition, we expect that the market price of the Depositary Shares will be influenced by yield and interest rates in the capital markets, the time remaining to the mandatory conversion date, our creditworthiness and the occurrence of certain events affecting us that do not require an adjustment to the fixed conversion rates. Fluctuations in yield rates in particular may give rise to arbitrage opportunities based upon changes in the relative

S-20

values of the Depositary Shares and our common stock. Any such arbitrage could, in turn, affect the market prices of our common stock and the Depositary Shares. The market price of our common stock could also be affected by possible sales of our common stock by investors who view the Depositary Shares as a more attractive means of equity participation in us and by hedging or arbitrage trading activity that we expect to develop involving our common stock. This trading activity could, in turn, affect the market price of the Depositary Shares.

Regulatory actions may adversely affect the trading price and liquidity of the Depositary Shares.

We expect that many investors in, and potential purchasers of, the Depositary Shares will employ, or seek to employ, a convertible arbitrage strategy with respect to the Depositary Shares. Investors would typically implement such a strategy by selling short the common stock underlying the convertible securities and dynamically adjusting their short position while continuing to hold the securities. Investors may also implement this type of strategy by entering into swaps on our common stock in lieu of or in addition to short selling the common stock.

The SEC and other regulatory and self-regulatory authorities have implemented various rules and taken certain actions, and may in the future adopt additional rules and take other actions, that may impact those engaging in short selling activity involving equity securities (including our common stock). Such rules and actions include Rule 201 of SEC Regulation SHO, the adoption by the Financial Industry Regulatory Authority, Inc. and the national securities exchanges of a “Limit Up-Limit Down” program, the imposition of market-wide circuit breakers that halt trading of securities for certain periods following specific market declines, and the implementation of certain regulatory reforms required by the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010. Any governmental or regulatory action that restricts the ability of investors in, or potential purchasers of, the Depositary Shares to effect short sales of our common stock, borrow our common stock or enter into swaps on our common stock could adversely affect the trading price and the liquidity of the Depositary Shares.

The fundamental change conversion rate and the payment of the fundamental change dividend make-whole amount upon the occurrence of certain fundamental changes may not adequately compensate you for the lost option value and lost dividends as a result of early conversion upon a fundamental change.

If a fundamental change (as defined under the section titled “Description of Mandatory Convertible Preferred Stock—Conversion at the Option of the Holder upon Fundamental Change; Fundamental Change Dividend Make-Whole Amount”) occurs on or prior to June 1, 2029, the fundamental change conversion rate will apply to any shares of Mandatory Convertible Preferred Stock (and, accordingly, the Depositary Shares) converted during the fundamental change conversion period (as defined under the section titled “Description of Mandatory Convertible Preferred Stock—Conversion at the Option of the Holder upon Fundamental Change; Fundamental Change Dividend Make-Whole Amount”) unless the stock price is less than $ or above $ (in each case, subject to adjustment) and, with respect to those shares of Mandatory Convertible Preferred Stock (and, accordingly, those Depositary Shares) converted, you will also receive, among other consideration, a fundamental change dividend make-whole amount, subject to our right to deliver shares of common stock in lieu of all or part of such amount and subject to the terms described under the section titled “Description of Mandatory Convertible Preferred Stock—Conversion at the Option of the Holder upon Fundamental Change; Fundamental Change Dividend Make-Whole Amount.” The number of shares of common stock to be issued upon conversion in connection with a fundamental change will be determined as described under the section titled “Description of Mandatory Convertible Preferred Stock—Conversion at the Option of the Holder upon Fundamental Change; Fundamental Change Dividend Make-Whole Amount.” Although the fundamental change conversion rate and the payment of the fundamental change dividend make-whole amount are generally designed to compensate you for the lost option value that you would suffer and the dividends you would lose as a result of converting your Depositary Shares representing our Mandatory Convertible Preferred Stock upon a fundamental change, the fundamental change conversion rate is also designed to compensate us for the lost option value that

S-21

we would suffer as a result of any such conversion. As a result, in many cases the fundamental change conversion rate will be less than the conversion rate that would apply upon mandatory conversion. The fundamental change conversion rate and fundamental change dividend make-whole amount are generally only an approximation of such lost option value and lost dividends and may not adequately compensate you for your actual loss. Furthermore, our obligation to deliver a number of shares of common stock per share of the Mandatory Convertible Preferred Stock (and your corresponding right to receive a proportionate number of shares of our common stock per Depositary Share) equal to the fundamental change conversion rate and pay the fundamental change dividend make-whole amount (whether paid or delivered, as the case may be, in cash or shares of our common stock) upon a conversion during the fundamental change conversion period could be considered a penalty under state law, in which case the enforceability thereof would be subject to general principles of reasonableness of economic remedies and therefore may not be enforceable in whole or in part.

The fixed conversion rates of the Mandatory Convertible Preferred Stock and, in turn, the Depositary Shares may not be adjusted for all dilutive events that may adversely affect the market price of the Depositary Shares or the common stock issuable upon conversion of the Mandatory Convertible Preferred Stock.

The fixed conversion rates of the Mandatory Convertible Preferred Stock and, in turn, the Depositary Shares, are subject to adjustment only for stock subdivisions and combinations, stock dividends and specified other transactions. See the section titled “Description of Mandatory Convertible Preferred Stock—Anti-Dilution Adjustments” for further discussion of anti-dilution adjustments. However, other events, such as grants under employee benefit or incentive plans, offerings of our common stock or other securities convertible into common stock (other than those set forth under the section titled “Description of Mandatory Convertible Preferred Stock—Anti-Dilution Adjustments”) for cash or in connection with acquisitions or third-party tender or exchange offers, which may adversely affect the market price of our common stock, may not result in any adjustment. Further, if any of these other events adversely affects the market price of our common stock, it may also adversely affect the market price of the Depositary Shares. In addition, the terms of our Mandatory Convertible Preferred Stock and the Depositary Shares do not restrict our ability to offer common stock or other securities convertible into common stock in the future, including offering a new series of preferred stock that ranks equally with our Mandatory Convertible Preferred Stock as to dividend payments and liquidation preference, or to engage in other transactions that could dilute our common stock. We have no obligation to consider the specific interests of the holders of our Mandatory Convertible Preferred Stock or the Depositary Shares in engaging in any such offering or transaction.

The Concurrent Financing Transactions, and the possibility of the sale or issuance of our common stock in the future, could reduce the market price of our common stock and, in turn, the Depositary Shares.

Concurrently with this offering and pursuant to a separate prospectus supplement, we are also making a public offering of $1.25 billion of shares of our common stock. In the Common Stock Offering, we expect to grant the underwriters of the Common Stock Offering an option to purchase up to an additional $187.5 million of shares of our common stock, solely to cover sales in excess of the firm shares. In addition, concurrently with this offering and pursuant to a separate prospectus supplement, we intend to enter into the Equity Distribution Agreement with certain agents under which we may sell up to $2 billion of shares of our common stock in the ATM Program from time to time. This offering is not conditioned on the closing of the Common Stock Offering or the entry into the ATM Program. Neither the closing of the Common Stock Offering nor entry into the ATM Program is conditioned upon the closing of this offering. We cannot assure you that the Common Stock Offering or the establishment of the ATM Program will be completed on the terms described herein, or at all.

S-22

company and have an adverse impact on the price of our common stock and, in turn, the Depositary Shares. In addition, a substantial number of shares of our common stock is reserved for issuance under our equity incentive plans and upon conversions of our 2.25% convertible senior notes due 2028 (the “2028 convertible senior notes”), our 3.50% convertible senior notes due 2029 (the “2029 convertible notes”) and our 0% convertible senior notes due 2030 (the “2030 convertible notes” and, together with the 2028 convertible notes and 2029 convertible notes, the “existing convertible notes”), and upon conversion of the Mandatory Convertible Preferred Stock, and we may also issue a substantial number of shares of our common stock to pay dividends on the Mandatory Convertible Preferred Stock. Furthermore, sales of a substantial amount of our common stock in the public market, or the perception that these sales or other issuances may occur, could reduce the market price of our common stock and, in turn, the Depositary Shares. This could also impair our ability to raise additional capital through the sale of our securities.

You will have no rights with respect to our common stock until you convert your Depositary Shares, but you may be adversely affected by certain changes made with respect to our common stock.

You will have no rights with respect to our common stock, including voting rights, rights to respond to common stock tender offers, if any, and rights to receive dividends or other distributions on our common stock, if any (other than through a conversion rate adjustment), prior to the conversion date with respect to a conversion of your Depositary Shares, but your investment in the Depositary Shares may be negatively affected by these events. Upon conversion, you will be entitled to exercise the rights of a holder of common stock only as to matters for which the record date occurs on or after the conversion date. For example, in the event that an amendment is proposed to our Amended and Restated Certificate of Incorporation or our Bylaws (as amended and restated) requiring stockholder approval and the record date for determining the stockholder of record entitled to vote on the amendment occurs prior to the conversion date, you will not be entitled to vote on the amendment, unless it would materially and adversely affect the special rights, preferences, privileges and voting powers of the Mandatory Convertible Preferred Stock, although you will nevertheless be subject to any changes in the powers, preferences or rights of our common stock.

You will have no voting rights except under limited circumstances, and you will need to act through the bank depositary to exercise voting rights with respect to our Mandatory Convertible Preferred Stock.

You do not have voting rights, except with respect to certain amendments to the terms of the Mandatory Convertible Preferred Stock, in the case of certain dividend arrearages, in certain other limited circumstances and except as specifically required by Delaware law. You will have no right to vote for any members of our board of directors except in the case of certain dividend arrearages. If dividends on any shares of the Mandatory Convertible Preferred Stock have not been declared and paid for the equivalent of six or more dividend periods (including, for the avoidance of doubt, the dividend period beginning on, and including, the initial issue date and ending on, but excluding, September 1, 2026), whether or not for consecutive dividend periods, the holders of shares of Mandatory Convertible Preferred Stock, voting together as a single class with holders of any and all other classes or series of our preferred stock ranking equally with the Mandatory Convertible Preferred Stock either as to dividends and the distribution of assets upon liquidation, winding-up or dissolution and having similar voting rights then outstanding, will be entitled to vote for the election of a total of two additional members of our board of directors, subject to the terms and limitations described under the section titled “Description of Mandatory Convertible Preferred Stock—Voting Rights.” This means that, except under the specific circumstances described under such section, you will not have the right to participate in any decisions regarding or affecting our company or your investment, including the election of directors or any extraordinary events, such as a merger, acquisition or other similar transaction. Decisions on those matters could be made in a manner that adversely affects your interests. Holders of Depositary Shares must act through the bank depositary to exercise any voting rights in respect of our Mandatory Convertible Preferred Stock.

S-23

Our Mandatory Convertible Preferred Stock will rank junior to all of our and our subsidiaries’ liabilities, as well as the capital stock of our subsidiaries held by third parties, in the event of a bankruptcy, liquidation, winding-up or dissolution of our or our subsidiaries’ assets.

In the event of a bankruptcy, liquidation, winding-up or dissolution, our assets will be available to make payments to holders of our Mandatory Convertible Preferred Stock only after all of our liabilities have been paid. In addition, our Mandatory Convertible Preferred Stock will rank structurally junior to all existing and future liabilities of our subsidiaries, as well as the capital stock of our subsidiaries held by third parties. Your rights to participate in the assets of our subsidiaries upon any liquidation or reorganization of any subsidiary will rank junior to the prior claims of that subsidiary’s creditors and third-party equity holders. In the event of a bankruptcy, liquidation, winding-up or dissolution, there may not be sufficient assets remaining, after paying our and our subsidiaries’ liabilities, to pay any amounts due to the holders of our Mandatory Convertible Preferred Stock then outstanding. As of March 31, 2026, excluding intercompany indebtedness, we had approximately $8.8 billion consolidated indebtedness for borrowed money outstanding.

We may issue preferred stock in the future that ranks equally with the Mandatory Convertible Preferred Stock with respect to dividends and liquidation rights, which may adversely affect the rights of holders of the Mandatory Convertible Preferred Stock or the Depositary Shares.

Without the consent of any holder of Mandatory Convertible Preferred Stock or Depositary Shares, we may authorize and issue preferred stock that ranks equally with the Mandatory Convertible Preferred Stock with respect to the payment of dividends or the distribution of assets upon our liquidation, dissolution or winding up. If we issue any such preferred stock in the future, the economic interests of holders of the Mandatory Convertible Preferred Stock and the Depositary Shares will be diluted and the value of our common stock, the Mandatory Convertible Preferred Stock and the Depositary Shares may decline.

Our ability to pay dividends on our Mandatory Convertible Preferred Stock may be limited.

Our payment of dividends on our Mandatory Convertible Preferred Stock in the future will be determined by our board of directors (or an authorized committee thereof) in its sole discretion and will depend on business conditions, our financial condition, earnings and liquidity, and other factors.

The Existing Credit Agreement contains, and the Amended Credit Agreement, if entered into, will contain, covenants that may restrict or limit our ability to pay cash dividends on our capital stock, including the Mandatory Convertible Preferred Stock, and/or require that certain conditions be satisfied or waived in order for such cash dividends to be paid in accordance with the Existing Credit Agreement or the Amended Credit Agreement, as applicable. The agreements governing any future indebtedness of ours may similarly restrict or limit our ability to pay cash dividends on our capital stock, including the Mandatory Convertible Preferred Stock. Therefore, we may be unable to pay dividends in cash on the Mandatory Convertible Preferred Stock.

In addition, under Delaware law, our board of directors (or an authorized committee thereof) may declare dividends on our capital stock (whether in cash or in shares of our common stock) only to the extent of our statutory “surplus” (which is defined as the amount equal to total assets minus total liabilities, in each case at fair market value, minus statutory capital), or if there is no such surplus, out of our net profits for the then-current and/or immediately preceding fiscal year. Further, even if we are permitted under our contractual obligations and Delaware law to pay cash dividends on the Mandatory Convertible Preferred Stock, we may not have sufficient cash to pay dividends in cash on the Mandatory Convertible Preferred Stock (and, in turn, on the Depositary Shares).

If upon mandatory conversion or an early conversion at the option of a holder (other than during a fundamental change conversion period, except in limited circumstances) we have not declared all or any portion of the accumulated and unpaid dividends payable on the Mandatory Convertible Preferred Stock for specified periods, the applicable conversion rate will be adjusted so that converting holders receive an additional number of shares

S-24

of common stock having a market value generally equal to the amount of such accumulated and unpaid dividends, subject to the limitations described under the section titled “Description of Mandatory Convertible Preferred Stock—Mandatory Conversion” and “Description of Mandatory Convertible Preferred Stock—Conversion at the Option of the Holder.” If upon an early conversion during the fundamental change conversion period we have not declared all or any portion of the accumulated and unpaid dividends payable on the Mandatory Convertible Preferred Stock for specified periods, we will pay the amount of such accumulated and unpaid dividends in cash, shares of our common stock or any combination thereof, in our sole discretion (or, in certain circumstances, make a corresponding adjustment to the conversion rate), subject in each case to the limitations described under the section titled “Description of Mandatory Convertible Preferred Stock—Conversion at the Option of the Holder upon Fundamental Change; Fundamental Change Dividend Make-Whole Amount.” In the case of mandatory conversion or conversion upon a fundamental change, if these limits to the adjustment of the conversion rate or the amount of such dividends payable in shares, as applicable, are reached, we will pay the shortfall in cash if we are legally permitted to do so and not restricted by the terms of our indebtedness at that time. We will not have an obligation to pay the shortfall in cash if these limits to the adjustment of the conversion rate are reached in the case of an early conversion at the option of the holder (or in the case of an early conversion during the fundamental change conversion period, if we are required to make an adjustment to the conversion rate in respect of any accumulated and unpaid dividends).

We conduct substantially all of our operations through our subsidiaries and will rely on our subsidiaries to pay cash dividends on the mandatory convertible preferred stock.

We conduct substantially all of our operations through our subsidiaries. Accordingly, our ability to obtain sufficient funds available to declare and pay dividends on the Mandatory Convertible Preferred Stock in cash will depend on the cash flows of our subsidiaries and their ability to make distributions to us. None of our subsidiaries is under any obligation to make payments to us, and any payments to us would depend on the earnings or financial condition of our subsidiaries and various business considerations. Statutory, contractual or other restrictions may also limit our subsidiaries’ ability to pay dividends or make distributions, loans or advances to us. For these reasons, we may not have access to any assets or cash flows of our subsidiaries to declare and pay cash dividends on the Mandatory Convertible Preferred Stock.

You may be subject to tax upon a distribution of dividends paid in shares of our common stock or an adjustment to the conversion rate of the Mandatory Convertible Preferred Stock or the Depositary Shares even though you do not receive a corresponding cash distribution.

We may elect to pay a dividend in whole or in part in shares of our common stock. Refer to the section titled “Description of Mandatory Convertible Preferred Stock—Dividends.” Although it is not free from doubt, these distributions should be treated for U.S. federal income tax purposes as if the holder received a distribution of cash in an amount equal to the fair market value of the distributed common stock on the date of the distribution and thus should generally be subject to the rules applicable to cash distributions (as discussed under the sections titled “Material U.S. Federal Income Tax Consequences—Taxation of U.S. Holders—Distributions” and “Material U.S. Federal Income Tax Consequences—Taxation of Non-U.S. Holders—Distributions” below).

The conversion rate of the Mandatory Convertible Preferred Stock and the Depositary Shares is subject to adjustment in certain circumstances. Refer to the section titled “Description of Mandatory Convertible Preferred Stock—Anti-Dilution Adjustments.” If, as a result of an adjustment (or failure to make an adjustment), your proportionate interest in our assets or earnings and profits is increased, you (as a holder of Depositary Shares, our Mandatory Convertible Preferred Stock, or our common stock) may be deemed to have received for U.S. federal income tax purposes a taxable dividend without the receipt of any cash or property. In the above circumstances, you may be subject to tax even though you receive no cash with which to pay that tax.

If you are a Non-U.S. Holder (as defined under the section titled “Material U.S. Federal Income Tax Consequences”), any dividend payable in shares of our common stock or deemed dividend generally will be

S-25

subject to U.S. federal withholding tax (currently at a 30% rate, or such lower rate as may be specified by an applicable treaty). If we (or an applicable withholding agent) are required to withhold on such distribution paid in shares of our common stock or deemed distribution and pay the applicable withholding taxes because such distribution or deemed distribution does not give rise to any cash from which any applicable withholding tax could be satisfied, we may, at our option, or an applicable withholding agent may, withhold such taxes from payments of cash or shares of common stock payable on the Depositary Shares, our Mandatory Convertible Preferred Stock or our common stock, sales proceeds subsequently paid or credited or other funds or assets of yours. Refer to the section titled “Material U.S. Federal Income Tax Consequences” for a further discussion of U.S. federal tax implications for U.S. Holders (as defined therein) and Non-U.S. Holders.

The accounting method for the Mandatory Convertible Preferred Stock may result in lower reported net earnings attributable to common stockholders and lower reported diluted earnings per share.

The accounting method for reflecting dividends on, and the conversion provisions of, the Mandatory Convertible Preferred Stock in our financial statements may adversely affect our reported earnings. For example, because dividends on the Mandatory Convertible Preferred Stock are cumulative, we expect that dividends that accumulate on the Mandatory Convertible Preferred Stock during the applicable reporting period, regardless of whether they are declared or paid, will be deducted from reported net earnings (or added to reported net loss) for that reporting period to arrive at reported earnings (or loss) attributable to our common stockholders. Accordingly, we expect this accounting treatment to reduce the amount of reported earnings (or increase the amount of reported loss) attributable to our common stockholders. Similarly, we expect that accumulated dividends on the Mandatory Convertible Preferred Stock will also reduce our reported basic earnings per share (or increase our reported basic loss per share) of common stock.

In addition, we expect that the if-converted method will apply to reflect the Mandatory Convertible Preferred Stock in the calculation of our diluted earnings per share. Under this method, we expect that diluted earnings per share will be calculated by adding back accumulated dividends on the Mandatory Convertible Preferred Stock to earnings attributable to common stockholders and assuming that the Mandatory Convertible Preferred Stock is converted at the beginning of the reporting period (or, if later, the time the Mandatory Convertible Preferred Stock is issued), unless the result would be anti-dilutive. Accordingly, the application of the if-converted method to the Mandatory Convertible Preferred Stock may result in lower reported diluted earnings per share.

We have not reached a final determination regarding the accounting treatment for the Mandatory Convertible Preferred Stock, and the description above is preliminary. We may account for the Mandatory Convertible Preferred Stock in a manner that is significantly different than described above. We cannot be sure whether other changes may be made to the current accounting standards related to the Mandatory Convertible Preferred Stock, or otherwise, that could have a material effect on our reported financial results.

Certain rights of the holders of the Mandatory Convertible Preferred Stock could delay or prevent an otherwise beneficial takeover or takeover attempt of us and, therefore, may affect the ability of holders of the Mandatory Convertible Preferred Stock to exercise their rights associated with a potential fundamental change.

Certain rights of the holders of the Mandatory Convertible Preferred Stock could make it more difficult or more expensive for a third party to acquire us. For example, if a fundamental change were to occur on or prior to June 1, 2029, holders of the Mandatory Convertible Preferred Stock may have the right to convert their shares of Mandatory Convertible Preferred Stock, in whole or in part, at an increased conversion rate and will also be entitled to receive a fundamental change dividend make-whole amount equal to the present value of all remaining dividend payments on their shares of Mandatory Convertible Preferred Stock. See the section titled “Description of Mandatory Convertible Preferred Stock—Conversion at the Option of the Holder upon Fundamental Change; Fundamental Change Dividend Make-Whole Amount.” These features of the Mandatory Convertible Preferred Stock could increase the cost of acquiring us or otherwise discourage a third party from acquiring us or removing incumbent management. In addition, provisions of Delaware law and our Amended and Restated Certificate of

S-26

Incorporation and Bylaws (as amended and restated) could make it more difficult for a third party to acquire control of us or have the effect of discouraging a third party from attempting to acquire control of us.

An active trading market for the Depositary Shares does not exist and may not develop.

The Depositary Shares are a new issue of securities with no established trading market. We intend to apply to list the Depositary Shares on the Nasdaq Global Select Market under the symbol “SMCIP.” However, no assurance can be given that our Depositary Shares will be listed or that any such application for listing will be approved. Even if the Depositary Shares are approved for listing on the Nasdaq Global Select Market, such listing does not guarantee that a trading market for the Depositary Shares will develop or, if a trading market for the Depositary Shares does develop, the depth or liquidity of that market or the ability of the holders to sell the Depositary Shares, or to sell the Depositary Shares at a favorable price.

The closing of this offering is not contingent upon the closing of the Common Stock Offering or entry into the ATM Program, and vice versa.

The closing of this offering is not contingent upon the closing of the Common Stock Offering or entry into the ATM Program. Neither the closing of the Common Stock Offering nor entry into the ATM Program is conditioned upon the closing of this offering. Therefore, it is possible that this offering occurs and the Common Stock Offering and/or the entry into the ATM Program do not occur, and vice versa. We cannot assure you that the Common Stock Offering will be completed or the ATM Program will be entered into on the terms described herein, or at all. Accordingly, if you decide to purchase Depositary Shares, you should be willing to do so whether or not we complete the Common Stock Offering or enter into the ATM Program. This prospectus supplement is not an offer to sell or a solicitation of an offer to buy any of the common stock being offered in the Common Stock Offering or that may be offered from time to time under the ATM Program.

The existing capped call transactions may affect the value of the Depositary Shares and our common stock.

In connection with the 2029 convertible notes and the 2030 convertible notes, we entered into capped call transactions (the “existing capped call transactions”) with certain financial institutions (the “existing option counterparties”). In connection with establishing their initial hedges of the existing capped call transactions, we have been advised that the existing option counterparties or their respective affiliates purchased shares of our common stock and/or entered into various derivative transactions with respect to our common stock concurrently with or shortly after the pricing of the 2029 convertible notes and 2030 convertible notes. We have been advised that the existing option counterparties or their respective affiliates may modify their hedge positions by entering into or unwinding various derivative transactions with respect to our common stock and/or purchasing or selling our common stock or other securities of ours in secondary market transactions prior to the maturity of the 2029 convertible notes and 2030 convertible notes (and are likely to do so during any observation period related to a conversion of the 2029 convertible notes and 2030 convertible notes and, to the extent we unwind a corresponding portion of the existing capped call transactions, following any repurchase or redemption of the 2029 convertible notes and 2030 convertible notes), which activity could coincide with the final averaging period related to the mandatory conversion of the Mandatory Convertible Preferred Stock offered hereby. This activity could also cause or avoid an increase or a decrease in the market price of our common stock or the Depositary Shares and could affect the value of the shares of common stock that you will receive upon conversion of the Mandatory Convertible Preferred Stock and, to the extent the activity occurs during the final averaging period related to the mandatory conversion of the Mandatory Convertible Preferred Stock, it could also affect the number of shares of our common stock that you will receive upon conversion.

The potential effect, if any, of these transactions and activities on the market price of our common stock or the Depositary Shares will depend in part on market conditions and cannot be ascertained at this time, but these activities could adversely affect the market price of our common stock and the Depositary Shares.

S-27

We are subject to counterparty risk with respect to the existing capped call transactions, and the existing capped call transactions may not operate as planned.

The existing option counterparties to the existing capped call transactions are, or are affiliates of, financial institutions, and we will be subject to the risk that they might default under the existing capped call transactions. Our exposure to the credit risk of the counterparties to the existing capped call transactions are not secured by any collateral. Global economic conditions have from time to time resulted in the actual or perceived failure or financial difficulties of many financial institutions. If any counterparty to the existing capped call transactions becomes subject to insolvency proceedings, we will become an unsecured creditor in those proceedings with a claim equal to our exposure at that time under our transactions with that counterparty. Our exposure will depend on many factors, but, generally, the increase in our exposure will be correlated with increases in the market price or the volatility of our common stock. In addition, upon a default by a counterparty to any existing capped call transaction, we may suffer more dilution than we currently anticipate with respect to our common stock. We can provide no assurances as to the financial stability or viability of any counterparty to the existing capped call transactions.

In addition, the existing capped call transactions are complex, and they may not operate as planned. For example, the terms of the existing capped call transactions may be subject to adjustment, modification or, in some cases, renegotiation if certain corporate or other transactions occur. Accordingly, these transactions may not operate as we intend if we are required to adjust their terms as a result of transactions in the future or upon unanticipated developments that may adversely affect the functioning of the existing capped call transactions.

Because the Depositary Shares will initially be held in book-entry form, holders of the Depositary Shares must rely on DTC’s procedures to exercise their rights and remedies.

We will initially issue the Depositary Shares in the form of one or more “global securities” registered in the name of Cede & Co., as nominee of The Depository Trust Company (“DTC”). Beneficial interests in global securities will be shown on, and transfers of global securities will be effected only through, the records maintained by DTC. Except in limited circumstances, we will not issue physical certificates representing the depositary shares. See “Description of Depositary Shares—Book-Entry, Settlement and Clearance.” Accordingly, if you own a beneficial interest in a global security, then you will not be considered an owner or holder of the Depositary Shares. Instead, DTC or its nominee will be the sole holder of the Depositary Shares. Payments of cash dividends and other cash amounts on global securities will be made to the paying agent, who will remit the payments to DTC. We expect that DTC will then credit those payments to the DTC participant accounts that hold book-entry interests in the global securities and that those participants will credit the payments to indirect DTC participants. Unlike persons who have physical certificates registered in their names, owners of beneficial interests in global securities will not have the direct right to act on our solicitations for consents or requests for waivers or other actions from holders of the Depositary Shares. Instead, those beneficial owners will be permitted to act only to the extent that they have received appropriate proxies to do so from DTC or, if applicable, a DTC participant. The applicable procedures for the granting of these proxies may not be sufficient to enable owners of beneficial interests in global securities to vote on any requested actions on a timely basis.

DTC procedures, and the procedures of DTC participants through whom investors hold any Depositary Shares, may delay the settlement of mandatory conversions.

The Depositary Shares will initially be held in book-entry form through the facilities of DTC and, accordingly, will be subject to DTC’s operational procedures and rules. Holders of the Depositary Shares representing any Mandatory Convertible Preferred Stock will be entitled to the consideration due upon the mandatory conversion of such Mandatory Convertible Preferred Stock. That consideration will be delivered in respect of the Depositary Shares in accordance with DTC’s procedures for mandatory conversions. Currently, mandatory conversions are processed through DTC’s procedures for mandatory stock-for-stock exchanges, which require, among other things, sufficient advance notice of the applicable “exchange rate” and special procedures for the calculation and

S-28

distribution of cash in lieu of the delivery of fractional securities. These notice and related requirements may not be satisfied in time for DTC to settle mandatory conversions within two business days of the mandatory conversion date of the Mandatory Convertible Preferred Stock. For example, we understand that DTC currently requests notification of the exchange rate for stock-for-stock exchanges at least five business days before the settlement date, which, in the case of a mandatory conversion of the Mandatory Convertible Preferred Stock, would be before the time the mandatory conversion rate will have been determined. Although we understand that DTC undertakes to process later notices on a best-effort basis, settlement may nonetheless be delayed.

Similarly, we understand that DTC conducts cash-in-lieu calculations on a DTC participant basis only after the shares of common stock due upon mandatory conversion have been allocated to DTC participants. This process may delay the delivery of cash in lieu of fractional shares of common stock. Furthermore, individual DTC participants may employ their own respective procedures to allocate shares and cash to individual customer accounts, which may further delay the delivery of those shares and cash to beneficial owners. We will have no control over DTC’s procedures or those of DTC participants that hold Depositary Shares on behalf of their customers. For these reasons, you may not receive the consideration due upon mandatory conversion of the Mandatory Convertible Preferred Stock represented by your Depositary Shares on the scheduled settlement date.

Risks Related to Ownership of our Common Stock

The trading price of our common stock has been and may in the future be volatile, which could result in substantial losses for investors in our common stock, including holders of any shares of common stock issued on conversion of, or as payment of dividends on, the Mandatory Convertible Preferred Stock.

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 matters such as the prior COVID-19 pandemic, a global economic downturn and regional conflict. 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, 2025 and Quarterly Reports on Form 10-Q for the quarters ended September 30, 2025, December 31, 2025 and March 31, 2026 and others, including:

•

if our common stock is delisted or the possibility thereof;

•

false or misleading press releases or articles regarding our company or our products;

•

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;

•

continued rapid evolution of the markets in which we compete, including AI;

•

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;

•

the loss of a key customer or supplier;

•

the loss of key personnel;

•

technological advancements rendering our products less valuable;

•

lawsuits filed against us;

•

negative publicity arising with respect to us, our employees, our third-party service providers or our partners;

S-29

•

changes in laws or regulations applicable to us (including export control regulations);

•

increased scrutiny from stockholders, regulators, and others regarding our corporate sustainability practices;

•

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;

•

additional issuances of our common stock or other equity-linked securities;

•

hedging activities by investors in the Depositary Shares or counterparties to the existing capped call transactions entered into in connection with our 2029 convertible notes and 2030 convertible notes; and

•

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

We may fail to meet our publicly announced guidance or other expectations about our business, which could cause our stock price to decline.

We provide guidance regarding our expected financial and business performance. Correctly identifying key factors affecting business conditions and predicting future events is inherently an uncertain process, and our guidance may not ultimately be accurate. If our guidance is not accurate or varies from actual results due to our inability to meet our assumptions or the impact on our financial performance that could occur as a result of various risks and uncertainties, the market value of our common stock could decline significantly.

Conversions of our existing convertible notes or the Mandatory Convertible Preferred Stock, the Common Stock Offering and/or future sales or issuances of our common stock or equity-linked securities, or the perception that these conversions, sales or issuances may occur, could lower the market price for our common stock.

We may conduct future offerings of our common stock, preferred stock, depositary shares or other securities that are convertible into or exercisable for our common stock to finance our operations or fund acquisitions, or for other purposes. For example, as of March 31, 2026, we had 54,450,016 shares of common stock issuable upon settlement or exercise, as applicable, of outstanding equity awards and 7,654,346 shares available for future issuance under our 2020 Equity and Incentive Compensation Plan. In addition, concurrently with this offering and pursuant to separate prospectus supplements, we are conducting the Concurrent Financing Transactions, pursuant to which we are (i) making a public offering of $1.25 billion of shares of our common stock (and up to an additional $187.5 million of shares of our common stock that the underwriters of the Common Stock Offering will have the option, exercisable within 30 days from the date of the prospectus supplement for the Common Stock Offering, to purchase from us to cover sales in excess of the firm shares) and (ii) intending to enter into an equity distribution agreement with certain agents under which we may sell up to $2 billion of shares of our common stock in “at-the-market” transactions from time to time. See the section titled “Concurrent Financing Transactions.”

The existence of the Mandatory Convertible Preferred Stock may encourage short selling by market participants because the conversion of the Mandatory Convertible Preferred Stock could be used to satisfy short positions, or the anticipated conversion of the Mandatory Convertible Preferred Stock into shares of common stock could depress the price of our common stock. The sale or the availability for sale of a large number of shares of common stock in the public market could cause the market price of our common stock to decline. In addition, sales under the ATM Program, if entered into, and any other future sales of our common stock and/or equity-linked securities in the public market, or the perception that such sales could occur, or the conversion of or the payment of dividends on our Mandatory Convertible Preferred Stock in the form of our common stock, or the perception that such conversions or dividends could occur, could negatively impact the market price of our common stock.

S-30

In the future, we may sell additional shares of our common stock to raise capital or acquire interests in other companies by using a combination of cash and our common stock or just our common stock or equity-linked securities such as the Mandatory Convertible Preferred Stock and the Depositary Shares offered hereby or our existing convertible notes. Any of these events may dilute your ownership interest in our company and have an adverse impact on the price of our common stock. Additionally, a substantial number of shares of our common stock is reserved for issuance upon conversions of our existing convertible notes, and will be reserved for issuance upon conversion of the Mandatory Convertible Preferred Stock and the Depositary Shares being offered hereby, and we may also issue a substantial number of shares of our common stock to pay dividends on such Mandatory Convertible Preferred Stock.

We cannot predict the size of future sales or issuances or the effect, if any, that they may have on the market price for our common stock. The issuance and sale of substantial amounts of common stock, or the conversion of our existing convertible notes or the Mandatory Convertible Preferred Stock, or the payment of dividends on our Mandatory Convertible Preferred Stock in the form of our common stock, or the perception that such issuances, sales, conversions or dividends may occur, could impair our ability to raise capital through the sale of additional equity securities.

In addition, the market price of our common stock could be depressed by possible sales of our common stock by investors who view the Depositary Shares as a more attractive means of equity participation in us than owning shares of common stock, or by hedging or arbitrage trading activity involving the Depositary Shares and our common stock.

We do not expect to pay any cash dividends on our common stock 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. Accordingly, holders of our common stock should rely on sales of their shares after price appreciation, which may never occur, as the only way to realize any future gains on their common stock.

Our common stock will rank junior to our Mandatory Convertible Preferred Stock with respect to dividends and amounts payable in the event of our liquidation, winding-up or dissolution.

Our common stock will rank junior to our Mandatory Convertible Preferred Stock with respect to the payment of dividends and amounts payable in the event of our liquidation, winding-up or dissolution. This means that, unless accumulated dividends have been paid or set aside for payment on all our outstanding Mandatory Convertible Preferred Stock through the most recently completed dividend period, no dividends may be declared or paid on our common stock subject to limited exceptions. Likewise, in the event of our voluntary or involuntary liquidation, winding-up or dissolution, no distribution of our assets may be made to holders of our common stock until we have paid to holders of our Mandatory Convertible Preferred Stock a liquidation preference equal to $1,000 per share plus accumulated and unpaid dividends.

We have broad discretion in the use of the net proceeds from this offering and the Concurrent Financing Transactions, if completed.

We expect the net proceeds from this offering to be approximately $ billion (or approximately $ billion if the underwriters exercise in full their over-allotment option to purchase additional Depositary Shares) after deducting the underwriting discounts and our estimated offering expenses payable by us. We estimate that the net proceeds to us from the Common Stock Offering, if completed, after deducting underwriting discounts and commissions and estimated expenses payable by us, will be approximately $ billion (or approximately $ billion if the underwriters of the Common Stock Offering exercise in full their option to purchase additional shares of common stock). Although we have described in this prospectus supplement, under the caption “Use of Proceeds,” how we currently intend to use the proceeds to us from this offering and the Concurrent Financing Transactions, our management will have broad discretion to apply the net proceeds, and investors will rely on our management’s judgment in spending the net proceeds. Our management may use the proceeds in ways that do not earn a profit or otherwise result in the creation of stockholder value.

S-31

USE OF PROCEEDS

We expect the net proceeds from this offering to be approximately $ billion (or approximately $ billion if the underwriters exercise in full their over-allotment option), after deducting the underwriting discounts and our estimated offering expenses totaling approximately $ million.

In addition, concurrently with this offering, we are offering $1.25 billion of shares of our common stock (or approximately $1.44 billion of shares of our common stock if the underwriters of the Common Stock Offering exercise in full their option to purchase additional shares of our common stock to cover sales in excess of the firm shares) in an underwritten offering pursuant to a separate prospectus supplement. We estimate that the net proceeds to us from the Common Stock Offering, if completed, after deducting underwriting discounts and commissions and estimated expenses payable by us, will be approximately $ billion (or approximately $ billion if the underwriters of the Common Stock Offering exercise in full their option to purchase additional common stock to cover sales in excess of the firm shares).

In addition, concurrently with this offering and pursuant to a separate prospectus supplement, we have entered into the Equity Distribution Agreement with under which we may sell up to $2 billion of shares of our common stock in the ATM Program from time to time.

S-32

DESCRIPTION OF THE CONCURRENT FINANCING TRANSACTIONS

Concurrently with this offering and pursuant to a separate prospectus supplement, we are making a public offering of $1.25 billion of shares of our common stock in the Common Stock Offering. We expect to grant the underwriters of the Common Stock Offering a 30-day option to purchase up to an additional $187.5 million of shares of our common stock to cover sales in excess of the firm shares. In addition, concurrently with this offering and pursuant to a separate prospectus supplement, we intend to enter into an Equity Distribution Agreement with certain agents under which we may sell up to $2 billion of shares of our common stock from time to time in the ATM Program. The closing of this offering is not conditioned upon the closing of the Common Stock Offering or entry into the ATM Program. Neither the closing of the Common Stock Offering nor entry into the ATM Program is conditioned upon the closing of this offering. We cannot assure you that the Common Stock Offering or the establishment of the ATM Program will be completed on the terms described herein, or at all. Nothing contained herein shall constitute an offer to sell or a solicitation of an offer to buy any of the common stock being offered in the Common Stock Offering or the common stock being offered from time to time in the ATM Program. The underwriters of this offering are also underwriters in the Common Stock Offering and agents in the ATM Program.

See the section titled “Use of Proceeds” for additional information regarding the use of proceeds from the Common Stock Offering.

S-33

DIVIDEND POLICY

No cash dividends have ever been paid or declared on our common stock. Other than with respect to dividends payable in respect of the Mandatory Convertible Preferred 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.

S-34

DESCRIPTION OF MANDATORY CONVERTIBLE PREFERRED STOCK

The following is a summary of certain terms of our % Series A Mandatory Convertible Preferred Stock, par value $0.001 per share, which we refer to in this prospectus supplement as our Mandatory Convertible Preferred Stock, but is not necessarily complete. The following summary supplements and, to the extent that it is inconsistent, replaces, the description of our preferred stock in the accompanying prospectus.

A copy of our Amended and Restated Certificate of Incorporation, as well as the certificate of designations for the Mandatory Convertible Preferred Stock and the form of Mandatory Convertible Preferred Stock share certificate, are available upon request from us at the address set forth under the section titled “Where You Can Find More Information” in the accompanying prospectus. The following summary of the terms of the Mandatory Convertible Preferred Stock is subject to, and qualified in its entirety by reference to, the provisions of such documents.

The bank depositary will initially be the sole holder of our Mandatory Convertible Preferred Stock. However, the holders of Depositary Shares will be entitled, through the bank depositary, to exercise the rights, preferences, privileges and voting powers of the holders of our Mandatory Convertible Preferred Stock, subject to the terms of the deposit agreement and as described under the section titled “Description of Depositary Shares” below. Each Depositary Share represents a 1/20th interest in a share of our Mandatory Convertible Preferred Stock.

As used in this section, the terms “us,” “we” or “our” refer to Super Micro Computer, Inc. and not any of its subsidiaries.

General

Under our Amended and Restated Certificate of Incorporation, our board of directors is authorized, without further stockholder action, to issue up to 10,000,000 shares of preferred stock, par value $0.001 per share, in one or more series, with such voting powers (if any), designations, preferences, and relative, participating, optional or other special rights, if any, and the qualifications, limitations or restrictions, as shall be set forth in the resolutions providing therefor. We currently do not have any shares of preferred stock outstanding. At the consummation of this offering, we will issue 3,750,000 shares of Mandatory Convertible Preferred Stock in the form of 75,000,000 Depositary Shares. In addition, we expect to grant the underwriters an option to purchase up to 11,250,000 additional Depositary Shares representing 562,500 shares of our Mandatory Convertible Preferred Stock, in accordance with the procedures set forth under the section titled “Underwriting.”

When issued, the Mandatory Convertible Preferred Stock and any common stock issued upon the conversion of the Mandatory Convertible Preferred Stock will be fully paid and nonassessable. The holders of the Mandatory Convertible Preferred Stock will have no preemptive or preferential rights to purchase or subscribe to stock, obligations, warrants or other securities of ours of any class. Computershare Trust Company, N.A. is the transfer agent and registrar of our common stock and will serve as transfer agent, registrar, conversion and dividend disbursing agent for the Mandatory Convertible Preferred Stock.

We do not intend to list our Mandatory Convertible Preferred Stock on any securities exchange or any automated dealer quotation system, but we do intend to apply to list the Depositary Shares on the Nasdaq Global Select Market as described under the section titled “Description of Depositary Shares—Listing.”

Ranking

The Mandatory Convertible Preferred Stock, with respect to dividend rights and/or distribution rights upon our liquidation, winding-up or dissolution, as applicable, ranks:

•

S-35

the “initial issue date”) the terms of which do not expressly provide that such capital stock ranks either (x) senior to the Mandatory Convertible Preferred Stock as to dividend rights or distribution rights upon our liquidation, winding-up or dissolution or (y) on parity with the Mandatory Convertible Preferred Stock as to dividend rights and distribution rights upon our liquidation, winding-up or dissolution (which we refer to collectively as “junior stock”);

•

junior to each other class or series of capital stock established after the initial issue date the terms of which expressly provide that such capital stock will rank senior to the Mandatory Convertible Preferred Stock as to dividend rights and distribution rights upon our liquidation, winding-up or dissolution (which we refer to collectively as “senior stock”); and

•

junior to our existing and future indebtedness and other liabilities (other than intercompany obligations).

As of March 31, 2026, excluding intercompany indebtedness, we had approximately $8.8 billion of consolidated indebtedness for borrowed money outstanding.

Dividends

Subject to the rights of holders of any class or series of capital stock ranking senior to the Mandatory Convertible Preferred Stock with respect to dividends, holders of shares of Mandatory Convertible Preferred Stock will be entitled to receive, when, as and if declared by our board of directors, or an authorized committee thereof, out of funds legally available for payment, cumulative dividends at the rate per annum of % on the liquidation preference of $1,000 per share of Mandatory Convertible Preferred Stock (equivalent to $ per annum per share), payable in cash, by delivery of shares of our common stock or through any combination of cash and shares of our common stock, as determined by our board of directors (or an authorized committee thereof) in its sole discretion (subject to the limitations described below). See the section titled “—Method of Payment of Dividends” below. Declared dividends on the Mandatory Convertible Preferred Stock will be payable quarterly on March 1, June 1, September 1 and December 1 of each year to, and including, June 1, 2029, commencing on, and including, September 1, 2026 (each, a “dividend payment date”), at such annual rate, and dividends shall accumulate from the most recent date as to which dividends shall have been paid or, if no dividends have been paid, from the initial issue date of the Mandatory Convertible Preferred Stock, whether or not in any dividend period or periods there have been funds legally available for the payment of such dividends. Declared dividends will be payable on the relevant dividend payment date to holders of record of the Mandatory Convertible Preferred Stock as they appear on our stock register at 5:00 p.m., New York City time, on the February 15, May 15, August 15 or November 15, as the case may be, immediately preceding the relevant dividend payment date (each, a “record date”), whether or not such holders convert their shares, or such shares are automatically converted, after a record date and on or prior to the immediately succeeding dividend payment date. These record dates will apply regardless of whether a particular record date is a business day. A “business day” means any day other than a Saturday or Sunday or any other day on which commercial banks in New York City are authorized or required by law or executive order to close. If a dividend payment date is not a business day, payment will be made on the next succeeding business day, without any interest or other payment in lieu of interest accruing with respect to this delay.

S-36

A full dividend period is the period from, and including, a dividend payment date to, but excluding, the next dividend payment date, except that the initial dividend period will commence on, and include, the initial issue date of our Mandatory Convertible Preferred Stock and will end on, and exclude, the September 1, 2026 dividend payment date. The amount of dividends payable on each share of Mandatory Convertible Preferred Stock for each full dividend period (after the initial dividend period) will be computed by dividing the annual dividend rate by four. Dividends payable on the Mandatory Convertible Preferred Stock for the initial dividend period and any partial dividend period will be computed based upon the actual number of days elapsed during such period over a 360-day year (consisting of twelve 30-day months). Accordingly, the dividend on the Mandatory Convertible Preferred Stock for the first dividend period, assuming the initial issue date is June , 2026, will be approximately $ per share (based on the annual dividend rate of % and a liquidation preference of $1,000 per share) and will be payable, when, as and if declared, on September 1, 2026. The dividend on the Mandatory Convertible Preferred Stock for each subsequent full dividend period, when, as and if declared, will be approximately $ per share (based on the annual dividend rate of % and a liquidation preference of $1,000 per share). Accumulated dividends on the Mandatory Convertible Preferred Stock will not bear interest if they are paid subsequent to the applicable dividend payment date.

No dividend will be declared or paid upon, or any sum of cash or number of shares of common stock set apart for the payment of dividends upon, any outstanding share of the Mandatory Convertible Preferred Stock with respect to any dividend period unless all dividends for all preceding dividend periods have been declared and paid upon, or a sufficient sum of cash or number of shares of common stock have been set apart for the payment of such dividends upon, all outstanding shares of Mandatory Convertible Preferred Stock.

Except as described above, dividends on shares of the Mandatory Convertible Preferred Stock converted to common stock will cease to accumulate, and all other rights of holders of the Mandatory Convertible Preferred Stock will terminate, from and after the mandatory conversion date, the fundamental change conversion date or the early conversion date (each, as defined below), as applicable.

Our ability to declare and pay cash dividends and make other distributions with respect to our capital stock, including the Mandatory Convertible Preferred Stock, may be limited by the terms of our and our subsidiaries’ existing and any indebtedness. In addition, our ability to declare and pay dividends may be limited by applicable Delaware law. See the section titled “Risk Factors—Risks Related to this Offering and Ownership of the Depositary Shares and the Mandatory Convertible Preferred Stock—Our ability to pay dividends on our Mandatory Convertible Preferred Stock may be limited.”

So long as any share of the Mandatory Convertible Preferred Stock remains outstanding, no dividend or distribution shall be declared or paid on the common stock or any other class or series of junior stock, and no common stock or other junior stock or parity stock shall be, directly or indirectly, purchased, redeemed or otherwise acquired for consideration by us or any of our subsidiaries unless, in each case, all accumulated and unpaid dividends for all preceding dividend periods have been declared and paid upon, or a sufficient sum of cash or number of shares of common stock have been set apart for the payment of such dividends upon, all outstanding shares of Mandatory Convertible Preferred Stock. The foregoing limitation shall not apply to: (i) a dividend payable on any common stock or other junior stock in shares of any common stock or other junior stock; (ii) the acquisition of shares of any common stock or other junior stock in exchange for, or a purchase, redemption or other acquisition for value of shares of any common stock or other junior stock with the proceeds of a substantially concurrent sale of, shares of any common stock or other junior stock and the payment of cash in lieu of any fractional share; (iii) purchases of fractional interests in shares of any common stock or other junior stock pursuant to the conversion or exchange provisions of such shares of other junior stock or any securities exchangeable for or convertible into such shares of common stock or other junior stock; (iv) redemptions, purchases or other acquisitions of shares of common stock or other junior stock in connection with any employment contract, benefit plan or other similar arrangement with or for the benefit of any one or more of our or our subsidiaries’ employees, officers, directors, consultants or independent contractors, including, without limitation, the forfeiture of unvested shares of restricted stock or share withholdings upon exercise, delivery or

S-37

vesting of equity awards and the payment of cash in lieu of any fractional share; (v) any dividends or distributions of rights or common stock or other junior stock in connection with a stockholders’ rights plan or any redemption or repurchase of rights pursuant to any stockholders’ rights plan, and the payment of cash in lieu of fractional shares; (vi) purchases of junior stock pursuant to a binding contract (including a stock repurchase plan) to make such purchases, if such contract was in effect before the initial issue date; (vii) the acquisition by us or any of our subsidiaries of record ownership in common stock or other junior stock or parity stock or on behalf of any other persons (other than us or any of our subsidiaries) that is a beneficial owner thereof, including as trustees or custodians; (viii) the exchange or conversion or reclassification of junior stock for or into other junior stock or of parity stock for or into other parity stock (with the same or lesser aggregate liquidation preference) and the payment of cash in lieu of fractional shares; or (ix) the settlement of any convertible note hedge transactions or capped call transactions entered into in connection with the issuance, by us or any of our subsidiaries, of the Depositary Shares or any debt securities that are convertible into, or exchangeable for, our common stock (or into or for any combination of cash and our common stock based on the value of our common stock), provided such convertible note hedge transactions or capped call transactions, as applicable, are on customary terms and were entered into (x) in connection with this offering of the Depositary Shares pursuant to this prospectus supplement, (y) before the initial issue date or (z) in compliance with the foregoing provision.

When dividends on shares of the Mandatory Convertible Preferred Stock have not been paid in full on any dividend payment date or declared and a sum of cash or number of shares of common stock sufficient for payment thereof set aside for the benefit of the holders thereof on the applicable record date, no dividends may be declared or paid on any parity stock unless dividends are declared on the Mandatory Convertible Preferred Stock such that the respective amounts of such dividends declared on the Mandatory Convertible Preferred Stock and each such other class or series of parity stock shall bear the same ratio to each other as all accumulated and unpaid dividends per share on the shares of the Mandatory Convertible Preferred Stock and such class or series of parity stock (which dollar amount will, if dividends on such class or series of parity stock are not cumulative, be the full amount of dividends per share thereof in respect of the most recent dividend period thereof) (subject to their having been declared by the board of directors, or an authorized committee thereof, out of legally available funds) bear to each other immediately prior to the payment of such dividends, in proportion to their respective liquidation preferences; provided that any unpaid dividends will continue to accumulate.

For the avoidance of doubt, the provisions described in this section will not prohibit or restrict the payment or other acquisition for value of any debt securities that are convertible into, or exchangeable for, any junior stock.

Subject to the foregoing, and not otherwise, such dividends (payable in cash, securities or other property) as may be determined by the board of directors, or an authorized committee thereof, may be declared and paid on any securities, including common stock and other junior stock, from time to time out of any funds legally available for such payment, and holders of the Mandatory Convertible Preferred Stock shall not be entitled to participate in any such dividends.

If we (or an applicable withholding agent) are required to withhold on distributions of common stock to a holder (see the section titled “Material U.S. Federal Income Tax Consequences”) and pay the applicable withholding taxes, we may, at our option, or an applicable withholding agent may, withhold such taxes from payments of cash or shares of common stock payable to, sales proceeds subsequently paid or credited to, or other funds or assets of, such holder.

Method of Payment of Dividends

Subject to the limitations described below, we may pay any declared dividend (or any portion of any declared dividend) on the Mandatory Convertible Preferred Stock (whether or not for a current dividend period or any prior dividend period), as determined by our board of directors (or an authorized committee thereof) in its sole discretion:

•

by paying cash;

S-38

•

by delivering shares of our common stock; or

•

through any combination of paying cash and delivering shares of our common stock.

We will make each payment of a declared dividend on the Mandatory Convertible Preferred Stock in cash, except to the extent we timely elect to make all or any portion of such payment in shares of our common stock. We will give the holders of the Mandatory Convertible Preferred Stock notice of any such election, and the portion of such payment that will be made in cash and the portion that will be made in common stock, on the earlier of the date we declare such dividend and the tenth scheduled trading day (as defined below) immediately preceding the dividend payment date for such dividend.

If we elect to make any payment of a declared dividend, or any portion thereof, in shares of our common stock, such shares shall be valued for such purpose at the average VWAP per share (as defined below) of our common stock over the five consecutive trading day period ending on, and including, the second trading day immediately preceding the applicable dividend payment date (the “five-day average price”), multiplied by 97%.

No fractional shares of common stock will be delivered to the holders of the Mandatory Convertible Preferred Stock in respect of dividends. We will instead pay a cash adjustment to each holder that would otherwise be entitled to a fraction of a share of common stock based on the five-day average price with respect to such dividend.

To the extent a shelf registration statement is required in our reasonable judgment in connection with the issuance of or for resales of common stock issued as payment of a dividend on the Mandatory Convertible Preferred Stock, including dividends paid in connection with a conversion, we will, to the extent such a shelf registration statement is not currently filed and effective, use our commercially reasonable efforts to file and maintain the effectiveness of such a shelf registration statement until the earlier of such time as all such shares of common stock have been resold thereunder and such time as all such shares are freely tradable without registration by holders thereof that are not, and have not been within the three months preceding, “affiliates” of ours for purposes of the Securities Act. To the extent applicable, we will also use our commercially reasonable efforts to have the shares of common stock qualified or registered under applicable state securities laws, if required, and approved for listing on the Nasdaq Global Select Market (or if our common stock is not listed on the Nasdaq Global Select Market, on the principal other U.S. national or regional securities exchange on which our common stock is then listed).

Notwithstanding the foregoing, in no event will the number of shares of our common stock delivered in connection with any declared dividend exceed a number equal to the amount of such declared dividend as to which we have elected to deliver shares of our common stock in lieu of paying cash divided by $ , which amount represents approximately 35% of the initial price (as defined below), subject to adjustment in a manner inversely proportional to any anti-dilution adjustment to each fixed conversion rate as set forth below under the section titled “—Anti-Dilution Adjustments” (such dollar amount, as adjusted, the “floor price”). To the extent that the amount of the declared dividend as to which we have elected to deliver shares of our common stock in lieu of paying cash exceeds the product of (x) the number of shares of common stock delivered in connection with such declared dividend and (y) 97% of the five-day average price applicable to such dividend, we will, if we are legally able to do so, and to the extent permitted under the terms of the documents governing any of our indebtedness, notwithstanding any notice by us to the contrary, pay such excess amount in cash.

No Redemption

We may not redeem the Mandatory Convertible Preferred Stock. However, at our option, we may purchase the Mandatory Convertible Preferred Stock or Depositary Shares from time to time in the open market, by tender offer, exchange offer or otherwise.

S-39

Liquidation Preference

In the event of our voluntary or involuntary liquidation, winding-up or dissolution, each holder of Mandatory Convertible Preferred Stock will be entitled to receive a liquidation preference in the amount of $1,000 per share of the Mandatory Convertible Preferred Stock (the “liquidation preference”), plus an amount equal to accumulated and unpaid dividends on the shares to, but excluding, the date fixed for liquidation, winding-up or dissolution to be paid out of our assets available for distribution to our stockholders, after satisfaction of liabilities owed to our creditors and holders of any senior stock and before any payment or distribution is made to holders of junior stock (including our common stock). If, upon our voluntary or involuntary liquidation, winding-up or dissolution, the amounts payable with respect to the liquidation preference, plus an amount equal to accumulated and unpaid dividends of the Mandatory Convertible Preferred Stock and all other parity stock are not paid in full, the holders of the Mandatory Convertible Preferred Stock and any such other parity stock will share equally and ratably in any distribution of our assets in proportion to the respective liquidation preferences and amounts equal to accumulated and unpaid dividends to which they are entitled. After payment of the full amount of the liquidation preference and an amount equal to accumulated and unpaid dividends to which they are entitled, the holders of the Mandatory Convertible Preferred Stock will have no right or claim to any of our remaining assets.

Neither the sale of all or substantially all of our assets or business (other than in connection with our liquidation, winding-up or dissolution), nor our merger or consolidation into or with any other person, or a statutory conversion or domestication, will be deemed to be our voluntary or involuntary liquidation, winding-up or dissolution.

The certificate of designations for our Mandatory Convertible Preferred Stock does not contain any provision requiring funds to be set aside to protect the liquidation preference of the Mandatory Convertible Preferred Stock even though it is substantially in excess of the par value thereof.

Voting Rights

The holders of the Mandatory Convertible Preferred Stock do not have voting rights other than those described below, except as specifically required by Delaware law.

Whenever dividends on any shares of Mandatory Convertible Preferred Stock have not been declared and paid for the equivalent of six or more dividend periods (including, for the avoidance of doubt, the dividend period beginning on, and including, the initial issue date and ending on, but excluding, September 1, 2026), whether or not for consecutive dividend periods (a “nonpayment”), the holders of such shares of Mandatory Convertible Preferred Stock, voting together as a single class with holders of any and all other series of voting preferred stock (as defined below) then outstanding, will be entitled at our next special or annual meeting of stockholders to vote for the election of a total of two additional members of our board of directors (the “preferred stock directors”); provided that the election of any such directors will not cause us to violate the corporate governance requirements of the Nasdaq Stock Market LLC (or any other exchange or automated quotation system on which our securities may be listed or quoted) that requires listed or quoted companies to have a majority of independent directors; provided further that our board of directors shall at no time include more than two preferred stock directors. In the event of a nonpayment, the authorized number of directors on our board of directors will be increased by two (or we will vacate the offices of two directors), and the new directors will be designated for election at an annual or special meeting of stockholders called by our board of directors, subject to its fiduciary duties, at the request of the holders of at least 25% of the shares of Mandatory Convertible Preferred Stock or of any other series of voting preferred stock (provided that if such request is not received at least 90 calendar days before the date fixed for the next annual or special meeting of stockholders, such election shall be held at such next annual or special meeting of stockholders), and at each subsequent annual meeting, so long as the holders of Mandatory Convertible Preferred Stock continue to have such voting rights. At any meeting at which the holders of the Mandatory Convertible Preferred Stock are entitled to elect preferred stock directors, the holders of record

S-40

of a majority of the then outstanding shares of the Mandatory Convertible Preferred Stock and all other series of voting preferred stock, present in person or represented by proxy, will constitute a quorum and the vote of the holders of a majority of such shares of the Mandatory Convertible Preferred Stock and other voting preferred stock so present or represented by proxy at any such meeting at which there shall be a quorum shall be sufficient to elect the preferred stock directors.

As used in this section, “voting preferred stock” means any class or series of our parity stock upon which like voting rights for the election of directors have been conferred and are exercisable. Whether a plurality, majority or other portion of the Mandatory Convertible Preferred Stock and any other voting preferred stock have been voted in favor of any matter shall be determined by reference to the respective liquidation preference amounts of the Mandatory Convertible Preferred Stock and such other voting preferred stock voted. For the avoidance of any doubt, holders of any voting preferred stock, including any outstanding Mandatory Convertible Preferred Stock, will collectively have the right, but only under the circumstances described above, to collectively elect no more than two preferred stock directors.

If and when all accumulated and unpaid dividends have been paid in full, or declared and a sum sufficient for such payment shall have been set aside (a “nonpayment remedy”), the holders of Mandatory Convertible Preferred Stock shall immediately and, without any further action by us, be divested of the foregoing voting rights, subject to the revesting of such rights in the event of each subsequent nonpayment. If such voting rights for the holders of Mandatory Convertible Preferred Stock and all other holders of voting preferred stock have terminated, the term of office of each preferred stock director so elected will terminate at such time and the number of directors on our board of directors shall automatically decrease by two.

Any preferred stock director may be removed at any time, with or without cause, by the holders of record of a majority in voting power of the outstanding shares of Mandatory Convertible Preferred Stock and any other series of voting preferred stock then outstanding (voting together as a single class) when they have the voting rights described above. In the event that a nonpayment shall have occurred and there shall not have been a nonpayment remedy, any vacancy in the office of a preferred stock director (other than prior to the initial election of preferred stock directors after a nonpayment) may be filled by the written consent of the preferred stock director remaining in office or, if none remains in office, by a vote of the holders of record of a majority in voting power of the outstanding shares of Mandatory Convertible Preferred Stock and any other series of voting preferred stock then outstanding (voting together as a single class) when they have the voting rights described above; provided that the filling of each vacancy will not cause us to violate the corporate governance requirements of the Nasdaq Stock Market LLC (or any other exchange or automated quotation system on which our securities may be listed or quoted) that requires listed or quoted companies to have a majority of independent directors. The preferred stock directors will each be entitled to one vote per director on any matter that comes before our board of directors for a vote.

So long as any shares of Mandatory Convertible Preferred Stock remain outstanding, we will not, without the affirmative vote or consent of the holders of at least two-thirds of the outstanding shares of Mandatory Convertible Preferred Stock given in person or by proxy, either in writing or at a meeting:

•

authorize or create, or increase the authorized amount of, any senior stock;

•

amend, alter or repeal the provisions of our Amended and Restated Certificate of Incorporation or the certificate of designations for the shares of Mandatory Convertible Preferred Stock so as to materially and adversely affect the special rights, preferences, privileges or voting powers of the shares of Mandatory Convertible Preferred Stock; or

•

consummate a binding share exchange or reclassification involving the shares of Mandatory Convertible Preferred Stock or a merger or consolidation of us with or into another entity, unless either (i) the shares of Mandatory Convertible Preferred Stock remain outstanding and have rights, preferences, privileges and voting powers, taken as a whole, that are no less favorable to the holders

S-41

thereof in any material respect than the special rights, preferences, privileges and voting powers of the Mandatory Convertible Preferred Stock immediately prior to such consummation, taken as a whole, or (ii) in the case of any such merger or consolidation with respect to which we are not the surviving or resulting entity, the shares of Mandatory Convertible Preferred Stock are converted into or exchanged for preference securities of the surviving or resulting entity or its ultimate parent, and such preference securities have special rights, preferences, privileges and voting powers, taken as a whole, that are no less favorable to the holders thereof in any material respect than the rights, preferences, privileges and voting powers of the Mandatory Convertible Preferred Stock immediately prior to such consummation, taken as a whole;

provided, however, that (1) any increase in the amount of our authorized but unissued shares of preferred stock, (2) any increase in the amount of authorized or issued shares of Mandatory Convertible Preferred Stock, (3) the creation and issuance, or an increase in the authorized or issued amount, of any series of junior stock or any other series of parity stock and (4) the application of the provisions described below under the section titled “—Recapitalizations, Reclassifications and Changes in our Common Stock,” will in each case be deemed not to materially and adversely affect the rights, preferences, privileges or voting powers of the Mandatory Convertible Preferred Stock and shall not require the affirmative vote or consent of holders of the Mandatory Convertible Preferred Stock.

Without the consent of the holders of the Mandatory Convertible Preferred Stock, we may amend, alter, supplement, or repeal any terms of the Mandatory Convertible Preferred Stock by amending or supplementing our Amended and Restated Certificate of Incorporation, the certificate of designations or any stock certificate representing shares of the Mandatory Convertible Preferred Stock for the following purposes:

•

to cure any ambiguity, omission, inconsistency or mistake in any such agreement or instrument;

•

to make any provision with respect to matters or questions relating to the Mandatory Convertible Preferred Stock that is not inconsistent with the provisions of the certificate of designations for the Mandatory Convertible Preferred Stock and that does not materially and adversely affect the rights of any holder of the Mandatory Convertible Preferred Stock; or

•

to make any other change that does not materially and adversely affect the rights of any holder of the Mandatory Convertible Preferred Stock (other than any holder that consents to such change).

In addition, without the consent of the holders of the Mandatory Convertible Preferred Stock, we may amend, alter, supplement or repeal any terms of the Mandatory Convertible Preferred Stock to (x) conform the terms of the Mandatory Convertible Preferred Stock to the description thereof in the accompanying prospectus as supplemented and/or amended by this “Description of Mandatory Convertible Preferred Stock” section of the preliminary prospectus supplement for the Mandatory Convertible Preferred Stock, as further supplemented and/or amended by the related pricing term sheet or (y) file a certificate of correction with respect to the certificate of designations for the Mandatory Convertible Preferred Stock to the extent permitted by Section 103(f) of the Delaware General Corporation Law.

Mandatory Conversion

Each outstanding share of the Mandatory Convertible Preferred Stock, unless previously converted, will automatically convert on the mandatory conversion date, into a number of shares of common stock equal to the conversion rate described below. If we declare a dividend on the Mandatory Convertible Preferred Stock for the dividend period ending on June 1, 2029, we will pay such dividend to the holders of record as of May 15, 2029, as described above under the section titled “—Dividends.” If, on or prior to May 15, 2029 we have not declared all or any portion of all accumulated and unpaid dividends on the Mandatory Convertible Preferred Stock through June 1, 2029, the conversion rate will be adjusted so that holders receive an additional number of shares of common stock equal to the amount of such accumulated and unpaid dividends that have not been declared (the

S-42

“additional conversion amount”), divided by the greater of (i) the floor price and (ii) 97% of the five-day average price (calculated as if the applicable dividend payment date were June 1, 2029). To the extent that the additional conversion amount per share of Mandatory Convertible Preferred Stock exceeds the product of such number of additional shares and 97% of such five-day average price, we will, if we are legally able to do so, and to the extent permitted under the terms of the documents governing any of our indebtedness, declare and pay such excess amount in cash pro rata per share to the holders of the Mandatory Convertible Preferred Stock.

The “conversion rate,” which is the number of shares of common stock issuable upon conversion of each share of Mandatory Convertible Preferred Stock on the mandatory conversion date (excluding any shares of our common stock issued in respect of accumulated but unpaid dividends, if any), will, subject to adjustment as described in “—Anti-Dilution Adjustments” below, be as follows:

•

if the “applicable market value” (as defined below) of our common stock is greater than the “threshold appreciation price,” then the conversion rate will be shares of common stock per share of Mandatory Convertible Preferred Stock (the “minimum conversion rate”), which is approximately equal to $1,000 divided by the threshold appreciation price;

•

if the applicable market value of our common stock is less than or equal to the threshold appreciation price but equal to or greater than the “initial price,” then the conversion rate will be equal to $1,000 divided by the applicable market value of our common stock, rounded to the nearest ten-thousandth of a share, which will be between and shares of common stock per share of Mandatory Convertible Preferred Stock; or

•

if the applicable market value of our common stock is less than the initial price, then the conversion rate will be shares of common stock per share of Mandatory Convertible Preferred Stock (the “maximum conversion rate”), which is approximately equal to $1,000 divided by the initial price.

For the avoidance of doubt, the conversion rate per share of the Mandatory Convertible Preferred Stock will in no event exceed the maximum conversion rate, subject to adjustment as described under “—Anti-Dilution Adjustments” below and exclusive of any amounts owing in respect of accumulated but unpaid dividends paid at our election in shares of common stock.

The “initial price” equals $1,000, divided by the maximum conversion rate, rounded to the nearest $0.0001, and is initially approximately equal to the per share public offering price of our common stock in the Common Stock Offering (or, if the Common Stock Offering does not price, the closing price of our common stock on June , 2026).

The “threshold appreciation price” equals $1,000, divided by the minimum conversion rate, rounded to the nearest $0.0001, and represents an approximately % appreciation over the initial price.

We refer to the minimum conversion rate and the maximum conversion rate collectively as the “fixed conversion rates.” The fixed conversion rates, the initial price, the threshold appreciation price and the applicable market value are each subject to adjustment as described under the section titled “—Anti-Dilution Adjustments” below.

Hypothetical Conversion Values Upon Mandatory Conversion

For illustrative purposes only, the following table shows the number of shares of our common stock that a holder of our Mandatory Convertible Preferred Stock would receive upon mandatory conversion of one share of Mandatory Convertible Preferred Stock at various applicable market values for our common stock. The table assumes that there will be no conversion rate adjustments as described below under the section titled “—Anti-Dilution Adjustments” and that dividends on the shares of Mandatory Convertible Preferred Stock will be declared and paid in cash. The actual applicable market value of shares of our common stock may differ from those set forth in the table below. Given an initial price of $ and a threshold appreciation price of

S-43

$ , a holder of our Mandatory Convertible Preferred Stock would receive on the mandatory conversion date the number of shares of our common stock per share of our Mandatory Convertible Preferred Stock set forth below, subject to the provisions described below with respect to any fractional share of common stock:


Applicable Market Value of our Common Stock	Number of Shares of our Common Stock to be Received Upon Conversion	Conversion Value (Applicable Market Value *Multiplied by* the Number of Shares of Our Common Stock to Be Received Upon Conversion)
$		$
$		$
$		$
$		$
$		$
$		$
$		$
$		$
$		$
$		$
$		$
$		$
$		$

Accordingly, if the applicable market value of our common stock is greater than the threshold appreciation price, the aggregate market value of our common stock delivered upon conversion of each share of the Mandatory Convertible Preferred Stock will be greater than the $1,000 liquidation preference of the share of the Mandatory Convertible Preferred Stock, assuming that the market price of our common stock on the mandatory conversion date is the same as the applicable market value of our common stock. If the applicable market value for our common stock is greater than or equal to the initial price and less than or equal to the threshold appreciation price, the aggregate market value of our common stock delivered upon conversion of each share of the Mandatory Convertible Preferred Stock will be equal to the $1,000 liquidation preference of the share of the Mandatory Convertible Preferred Stock, assuming that the market price of our common stock on the mandatory conversion date is the same as the applicable market value of our common stock. If the applicable market value of our common stock is less than the initial price, the aggregate market value of our common stock delivered upon conversion of each share of the Mandatory Convertible Preferred Stock will be less than the $1,000 liquidation preference of the share of the Mandatory Convertible Preferred Stock, assuming that the market price of our common stock on the mandatory conversion date is the same as the applicable market value of our common stock.

Definitions

“Applicable market value” means the average VWAP per share of our common stock over the final averaging period.

“Final averaging period” means the 20 consecutive trading day period beginning on, and including, the 21st scheduled trading day immediately preceding June 1, 2029.

“Mandatory conversion date” means the second business day immediately following the last trading day of the final averaging period. The “mandatory conversion date” is expected to be June 1, 2029.

“Market disruption event” means (i) a failure by the primary U.S. national or regional securities exchange or market on which our common stock is listed or admitted for trading to open for trading during its regular trading session or (ii) the occurrence or existence prior to 1:00 p.m., New York City time, on any scheduled trading day

S-44

for our common stock for more than one half-hour period in the aggregate during regular trading hours of any suspension or limitation imposed on trading (by reason of movements in price exceeding limits permitted by the relevant stock exchange or otherwise) in our common stock or in any options contracts or futures contracts relating to our common stock.

A “scheduled trading day” is any day that is scheduled to be a trading day.

“Trading day” means a day on which (i) there is no “market disruption event” (as defined below) and (ii) trading in our common stock generally occurs on the Nasdaq Global Select Market or, if our common stock is not then listed on the Nasdaq Global Select Market, on the principal other U.S. national or regional securities exchange on which our common stock is then listed or, if our common stock is not then listed on a U.S. national or regional securities exchange, on the principal other market on which our common stock is then listed or admitted for trading. If our common stock is not so listed or admitted for trading, “trading day” means a “business day.”

“VWAP” per share of our common stock on any trading day means the per share volume-weighted average price as displayed on Bloomberg page “SMCI <EQUITY> AQR” (or its equivalent successor if such page is not available) in respect of the period from 9:30 a.m. to 4:00 p.m., New York City time (or, if the scheduled close of trading of the primary session for the primary U.S. national or regional securities exchange or market on which our common stock is listed or admitted for trading on such trading day is earlier, such earlier scheduled close of trading), on such trading day; or, if such price is not available, “VWAP” means the market value per share of our common stock on such trading day as determined, using a volume-weighted average method, by a nationally recognized independent investment banking firm retained by us for this purpose, which may include any of the underwriters for this offering. The “average VWAP” per share over a certain period means the arithmetic average of the VWAP per share for each trading day in such period.

Conversion at the Option of the Holder

Other than during a “fundamental change conversion period” (as defined below under the section titled “—Conversion at the Option of the Holder upon Fundamental Change; Fundamental Change Dividend Make-Whole Amount”), holders of the Mandatory Convertible Preferred Stock have the right to convert their shares of Mandatory Convertible Preferred Stock, in whole or in part (but in no event less than one share of Mandatory Convertible Preferred Stock), at any time prior to June 1, 2029, into shares of our common stock at the minimum conversion rate, subject to adjustment as described under the section titled “—Anti-Dilution Adjustments” below.

If, as of the effective date of any early conversion (the “early conversion date”), we have not declared all or any portion of the accumulated and unpaid dividends for all full dividend periods ending on or prior to the dividend payment date immediately preceding such early conversion date, the conversion rate will be adjusted so that converting holders receive an additional number of shares of common stock equal to such amount of accumulated and unpaid dividends that have not been declared for such full dividend periods (the “early conversion additional amount”), divided by the greater of (i) the floor price and (ii) the average VWAP per share of our common stock over the 20 consecutive trading day period ending on, and including, the second trading day immediately preceding the early conversion date (the “early conversion average price”). Notwithstanding the last sentence under “—Method of Payment of Dividends” above, to the extent that the early conversion additional amount exceeds the product of such number of additional shares and the early conversion average price, we will not have any obligation to pay the shortfall in cash.

Except as described in the immediately preceding paragraph, upon any optional conversion of any shares of the Mandatory Convertible Preferred Stock pursuant to this “—Conversion at the Option of the Holder” section, we will make no payment or allowance for unpaid dividends on such shares of the Mandatory Convertible Preferred Stock, unless such early conversion date occurs after the record date for a declared dividend and on or prior to the immediately succeeding dividend payment date, in which case such dividend will be paid on such dividend payment date to the holder of record of the converted shares of Mandatory Convertible Preferred Stock as of such record date, as described under “—Dividends.”

S-45

Conversion at the Option of the Holder upon Fundamental Change; Fundamental Change Dividend Make-Whole Amount

General

If a “fundamental change” (as defined below) occurs on or prior to June 1, 2029, holders of the Mandatory Convertible Preferred Stock will have the right (the “fundamental change early conversion right”) to: (i) convert their shares of Mandatory Convertible Preferred Stock, in whole or in part (but in no event less than one share of Mandatory Convertible Preferred Stock), into a number of shares of common stock equal to the fundamental change conversion rate per share of Mandatory Convertible Preferred Stock described below; (ii) with respect to such converted shares, receive an amount equal to the present value, as of the “effective date” (as defined below), calculated using a discount rate of % per annum, of all scheduled dividend payments on such shares (excluding any accumulated and unpaid dividends for any dividend period prior to the effective date of the fundamental change, including for the partial dividend period, if any, from, and including, the dividend payment date immediately preceding the effective date to, but excluding, the effective date (collectively, the “accumulated dividend amount”)) for all the remaining full dividend periods and for the partial dividend period from, and including, the effective date to, but excluding, the next dividend payment date (the “fundamental change dividend make-whole amount”); and (iii) with respect to such converted shares, to the extent that, as of the effective date of the fundamental change, there is any accumulated dividend amount, receive payment of the accumulated dividend amount (clauses (ii) and (iii), together, the “make-whole dividend amount”), in the case of clauses (ii) and (iii), subject to our right to deliver shares of our common stock in lieu of all or part of such amounts as described under the section titled “—Make-Whole Dividend Amount” below; provided that, if the effective date or the conversion date for the fundamental change (the “fundamental change conversion date”) falls after the record date for a declared dividend and prior to the next dividend payment date, such dividend will be paid on such dividend payment date to the holders of record of the Mandatory Convertible Preferred Stock at 5:00 p.m., New York City time on the immediately preceding record date, as described under the section titled “—Dividends,” such dividend will not be included in the accumulated dividend amount, and the fundamental change dividend make-whole amount will not include the present value of the payment of such dividend.

To exercise the fundamental change early conversion right, holders must submit their shares of the Mandatory Convertible Preferred Stock for conversion at any time during the period (the “fundamental change conversion period”) beginning on, and including, the effective date of such fundamental change (the “effective date”) and ending at 5:00 p.m., New York City time, on the date that is the earlier of (a) 20 calendar days after the effective date (or, if later, the date that is 20 calendar days after holders receive notice of such fundamental change) and (b) June 1, 2029. For the avoidance of doubt, the fundamental change conversion period may not end on a date that is later than June 1, 2029. Holders of Mandatory Convertible Preferred Stock who submit their shares for conversion during the fundamental change conversion period will have such shares converted at the conversion rate specified in the table below (the “fundamental change conversion rate”) and will be entitled to receive the make-whole dividend amount. Holders of Mandatory Convertible Preferred Stock who do not submit their shares for conversion during the fundamental change conversion period will not be entitled to convert their shares of Mandatory Convertible Preferred Stock at the relevant fundamental change conversion rate or to receive the relevant make-whole dividend amount.

We will notify holders of the effective date of a fundamental change no later than the second business day following such effective date. If we notify holders of a fundamental change later than the second business day following the effective date, the fundamental change conversion period will be extended by a number of days equal to the number of days from, and including, such effective date to, but excluding, the date of the notice; provided, however, that the fundamental change conversion period will not be extended beyond June 1, 2029.

A “fundamental change” will be deemed to have occurred at the time any of the following occurs after the initial issue date of the Mandatory Convertible Preferred Stock:

(1) a “person” or “group” (within the meaning of Section 13(d)(3) of the Exchange Act), other than us or our wholly owned subsidiaries, has become the direct or indirect “beneficial owner” (as defined below) of shares of our common equity representing more than 50% of the voting power of all of our then-outstanding common equity;

S-46

(2) the consummation of: (A) any sale, lease or other transfer, in one transaction or a series of transactions, of all or substantially all of the assets of us and our subsidiaries, taken as a whole, to any person; or (B) any transaction or series of related transactions in connection with which (whether by means of merger, consolidation, share exchange, combination, reclassification, recapitalization, acquisition, liquidation or otherwise) all of our common stock is exchanged for, converted into, acquired for, or constitutes solely the right to receive, other securities, cash or other property; provided, however, that any merger, consolidation, share exchange or combination of us pursuant to which the persons that directly or indirectly “beneficially owned” (as defined below) all classes of our common equity immediately before such transaction directly or indirectly “beneficially own,” immediately after such transaction, more than 50% of all classes of common equity of the surviving, continuing or acquiring company or other transferee, as applicable, or the parent thereof, in substantially the same proportions vis-à -vis each other as immediately before such transaction will be deemed not to be a fundamental change pursuant to this clause (2);

(3) our stockholders approve any plan or proposal for our liquidation or dissolution; or

(4) our common stock ceases to be listed on any of The New York Stock Exchange, the Nasdaq Global Market or the Nasdaq Global Select Market (or any of their respective successors);

provided, however, that a transaction or event described in clause (1) or (2) above will not constitute a fundamental change if at least 90% of the consideration received or to be received by the holders of our common stock (excluding cash payments for fractional shares or pursuant to dissenters rights), in connection with such transaction or event, consists of shares of common stock listed on any of The New York Stock Exchange, the Nasdaq Global Market or the Nasdaq Global Select Market (or any of their respective successors), or that will be so listed when issued or exchanged in connection with such transaction or event, and as a result of such transaction or event the Mandatory Convertible Preferred Stock becomes convertible into or exchangeable for such consideration, excluding cash payments for fractional shares or pursuant to dissenters’ appraisal rights.

For the purposes of this definition, (x) any transaction or event described in both clause (1) and in clause (2)(A) or (B) above (without regard to the proviso in clause (2)) will be deemed to occur solely pursuant to clause (2) above (subject to such proviso); and (y) whether a person is a “beneficial owner” and whether shares are “beneficially owned” will be determined in accordance with Rule 13d-3 under the Exchange Act.

If any transaction in which our common stock is replaced by the securities of another entity occurs, following completion of any related fundamental change conversion period (or, if none, on the effective date of such transaction), references to us in the definition of “fundamental change” above shall instead be references to such other entity.

Fundamental Change Conversion Rate

The fundamental change conversion rate will be determined by reference to the table below and is based on the effective date of the fundamental change and the price (the “stock price”) paid (or deemed paid) per share of our common stock in such transaction. If all holders of our common stock receive only cash in exchange for their common stock in the fundamental change, the stock price shall be the cash amount paid per share. Otherwise, the stock price shall be the average VWAP per share of our common stock over the five consecutive trading day period ending on, and including, the trading day immediately preceding the effective date of the relevant fundamental change.

The stock prices set forth in the first row of the table (i.e., the column headers) will be adjusted as of any date on which the fixed conversion rates of our Mandatory Convertible Preferred Stock are adjusted. The adjusted stock prices will equal the stock prices applicable immediately prior to such adjustment, multiplied by a fraction, the numerator of which is the minimum conversion rate immediately prior to the adjustment giving rise to the stock price adjustment and the denominator of which is the minimum conversion rate as so adjusted. Each of the

S-47

fundamental change conversion rates in the table will be subject to adjustment in the same manner and at the same time as each fixed conversion rate as set forth under the section titled “—Anti-Dilution Adjustments.”

The following table sets forth the fundamental change conversion rate per share of Mandatory Convertible Preferred Stock for each stock price and effective date set forth below.

Stock Price

Effective Date

June , 2026

June 1, 2027

June 1, 2028

June 1, 2029

The exact stock price and effective date may not be set forth in the table, in which case:

•

if the stock price is between two stock prices on the table or the effective date is between two effective dates on the table, the fundamental change conversion rate will be determined by straight-line interpolation between the fundamental change conversion rates set forth for the higher and lower stock prices and the earlier and later effective dates, as applicable, based on a 365-day or 366-day year, as applicable;

•

if the stock price is in excess of $ per share (subject to adjustment in the same manner as the column headings of the table above are adjusted pursuant to the provision described in the second paragraph under this “—Fundamental Change Conversion Rate”), then the fundamental change conversion rate will be the minimum conversion rate; and

•

if the stock price is less than $ per share (subject to adjustment in the same manner as the column headings of the table above are adjusted pursuant to the provision described in the second paragraph under this “—Fundamental Change Conversion Rate”), then the fundamental change conversion rate will be the maximum conversion rate.

Make-Whole Dividend Amount

For any shares of Mandatory Convertible Preferred Stock that are converted during the fundamental change conversion period, subject to the limitations described below, in addition to the common stock issued upon conversion at the fundamental change conversion rate, we may pay the make-whole dividend amount, determined in our sole discretion:

•

by paying cash;

•

by delivering shares of our common stock; or

•

through any combination of paying cash and delivering shares of our common stock.

We will pay the make-whole dividend amount in cash, except to the extent we elect on or prior to the second business day following the effective date of a fundamental change to make all or any portion of such payments by delivering shares of our common stock. If we elect to make any payment of the make-whole dividend amount, or any portion thereof, in shares of our common stock, such shares shall be valued for such purpose at 97% of the stock price.

No fractional shares of common stock will be delivered to the holders of the Mandatory Convertible Preferred Stock in respect of the make-whole dividend amount. We will instead pay a cash adjustment to each converting holder that would otherwise be entitled to a fraction of a share of common stock based on the average VWAP per share of our common stock over the five consecutive trading day period ending on, and including, the second trading day immediately preceding the fundamental change conversion date.

S-48

Notwithstanding the foregoing, with respect to any conversion of Mandatory Convertible Preferred Stock during the fundamental change conversion period, in no event will the number of shares of our common stock that we deliver in lieu of paying all or any portion of the make- whole dividend amount in cash exceed a number equal to the portion of the make-whole dividend amount to be paid by the delivery of common stock, divided by the greater of (i) the floor price and (ii) 97% of the stock price. To the extent that the portion of the make-whole dividend amount as to which we have elected to deliver shares of common stock in lieu of paying cash exceeds the product of the number of shares of common stock delivered in respect of such portion of the make-whole dividend amount and 97% of the stock price, we will, if we are legally able to do so, and to the extent permitted under the terms of the documents governing any of our indebtedness, notwithstanding any notice by us to the contrary, pay such excess amount in cash.

In addition, if we are prohibited from paying or delivering, as the case may be, the make-whole dividend amount (whether in cash or in shares of our common stock), in whole or in part, due to limitations of applicable Delaware law, the fundamental change conversion rate will instead be increased by a number of shares of common stock equal to the cash amount of the aggregate unpaid and undelivered make-whole dividend amount, divided by the greater of (i) the floor price and (ii) 97% of the stock price. To the extent that the cash amount of the aggregate unpaid and undelivered make-whole dividend amount exceeds the product of such number of additional shares and 97% of the stock price, we will not have any obligation to pay the shortfall in cash.

Not later than the second business day following the effective date of a fundamental change, we will notify holders of:

•

the fundamental change conversion rate;

•

the fundamental change dividend make-whole amount and whether we will pay such amount, or any portion thereof, in shares of our common stock and, if applicable, the portion of such amount that will be paid in common stock; and

•

the accumulated dividend amount and whether we will pay such amount, or any portion thereof, in shares of our common stock and, if applicable, the portion of such amount that will be paid in common stock.

Our obligation to adjust the conversion rate in connection with a fundamental change and pay the fundamental change dividend make-whole amount (whether in cash, shares of our common stock or any combination thereof) could possibly be considered a penalty, in which case the enforceability thereof would be subject to general principles of reasonableness of economic remedies and therefore may not be enforceable in whole or in part.

Conversion Procedures

Upon Mandatory Conversion

Any outstanding shares of Mandatory Convertible Preferred Stock will automatically convert into shares of common stock on the mandatory conversion date. The person or persons entitled to receive the shares of common stock issuable upon mandatory conversion of the Mandatory Convertible Preferred Stock will be treated as the record holder(s) of such shares as of 5:00 p.m., New York City time, on the mandatory conversion date. Except as provided under the section titled “—Anti-Dilution Adjustments,” prior to 5:00 p.m., New York City time, on the mandatory conversion date, the shares of common stock issuable upon conversion of the Mandatory Convertible Preferred Stock will not be deemed to be outstanding for any purpose and holders of the Mandatory Convertible Preferred Stock will have no rights with respect to such shares of common stock, including voting rights, rights to respond to tender offers and rights to receive any dividends or other distributions on the common stock, by virtue of holding the Mandatory Convertible Preferred Stock.

Upon Early Conversion

If a holder elects to convert its shares of Mandatory Convertible Preferred Stock prior to June 1, 2029, in the manner described under the section titled “—Conversion at the Option of the Holder” or “—Conversion at the

S-49

Option of the Holder upon Fundamental Change; Fundamental Change Dividend Make-Whole Amount,” such holder must observe the conversion procedures set forth below.

If such holder holds a beneficial interest in a global share of Mandatory Convertible Preferred Stock, to convert its shares of Mandatory Convertible Preferred Stock early, such holder must deliver to DTC the appropriate instruction form for conversion pursuant to DTC’s conversion program and, if such holder’s shares of Mandatory Convertible Preferred Stock are held in certificated form, such holder must comply with certain procedures set forth in the certificate of designations.

The conversion date will be the date on which the converting holder has satisfied the foregoing requirements; provided that, for the avoidance of doubt, in no event may such conversion date occur after June 1, 2029. A holder that early converts its shares of Mandatory Convertible Preferred Stock will not be required to pay any stock transfer and documentary stamp or similar taxes or duties relating to the issuance or delivery of our common stock if such holder exercises its early conversion rights, except that such holder will be required to pay any such tax or duty that may be payable relating to any transfer involved in the issuance or delivery of the common stock in a name other than the name of such holder. Shares of common stock will be issued and delivered and payment by us of any cash to which the converting holder is entitled will be made only after all applicable taxes and duties, if any, payable by the converting holder have been paid in full and such shares of common stock will be issued, and the payment by us of such cash to which the converting holder is entitled will be made, in each case, on the later of the second business day immediately succeeding the conversion date and the business day after such holder has paid in full all applicable taxes and duties, if any.

The person or persons entitled to receive the shares of common stock issuable upon early conversion of the Mandatory Convertible Preferred Stock will be treated as the record holder(s) of such shares as of 5:00 p.m., New York City time, on the applicable conversion date. Prior to 5:00 p.m., New York City time, on the applicable conversion date, the shares of common stock issuable upon early conversion of the Mandatory Convertible Preferred Stock will not be deemed to be outstanding for any purpose and a holder of shares of the Mandatory Convertible Preferred Stock will have no rights with respect to such shares of common stock, including voting rights, rights to respond to tender offers for the common stock and rights to receive any dividends or other distributions on the common stock, by virtue of holding the Mandatory Convertible Preferred Stock.

Fractional Shares

No fractional shares of common stock will be issued to holders of our Mandatory Convertible Preferred Stock upon conversion. In lieu of any fractional shares of common stock otherwise issuable in respect of the aggregate number of shares of our Mandatory Convertible Preferred Stock of any holder that are converted, that holder will be entitled to receive an amount in cash (computed to the nearest cent) equal to the product of: (i) that same fraction; and (ii) the average VWAP per share of our common stock over the five consecutive trading day period ending on, and including, the second trading day immediately preceding the relevant conversion date.

Subject to any applicable rules and procedures of DTC, if more than one share of our Mandatory Convertible Preferred Stock is surrendered for conversion at one time by or for the same holder, the number of shares of our common stock issuable upon conversion thereof shall be computed on the basis of the aggregate number of shares of our Mandatory Convertible Preferred Stock so surrendered.

Anti-Dilution Adjustments

Each fixed conversion rate will be adjusted if:

(1)	We issue common stock to all or substantially all holders of our common stock as a dividend or other distribution, in which event, each fixed conversion rate in effect immediately prior to 5:00 p.m., New York

S-50

City time, on the date fixed for determination of the holders of our common stock entitled to receive such dividend or other distribution will be multiplied by a fraction:

•

the numerator of which is the sum of (x) the number of shares of our common stock outstanding immediately prior to 5:00 p.m., New York City time, on the date fixed for such determination and (y) the total number of shares of our common stock constituting such dividend or other distribution; and

•

the denominator of which is the number of shares of our common stock outstanding immediately prior to 5:00 p.m., New York City time, on the date fixed for such determination.

Any increase made pursuant to this clause (1) will become effective immediately after 5:00 p.m., New York City time, on the date fixed for such determination. If any dividend or distribution described in this clause (1) is declared but not so paid or made, each fixed conversion rate shall be decreased, effective as of the date our board of directors, or an authorized committee thereof, publicly announces its decision not to make such dividend or distribution, to such fixed conversion rate that would be in effect if such dividend or distribution had not been declared. For the purposes of this clause (1), the number of shares of common stock outstanding immediately prior to 5:00 p.m., New York City time, on the date fixed for such determination shall not include shares held in treasury but shall include any shares issuable in respect of any scrip certificates issued in lieu of fractions of shares of common stock. We will not pay any dividend or make any distribution on shares of common stock held in treasury.

(2)

We issue to all or substantially all holders of our common stock rights or warrants (other than rights or warrants issued pursuant to a stockholders’ rights plan, customary dividend reinvestment plan or customary share purchase plan or other similar plans) entitling them, for a period of up to 45 calendar days after the announcement date of such issuance, to subscribe for or purchase our shares of common stock at a price per share less than the “current market price” (as defined below) of our common stock, in which case each fixed conversion rate in effect immediately prior to 5:00 p.m., New York City time, on the date fixed for determination of the holders of our common stock entitled to receive such rights or warrants will be increased by multiplying such fixed conversion rate by a fraction:

•

the numerator of which is the sum of (x) the number of shares of common stock outstanding immediately prior to 5:00 p.m., New York City time, on the date fixed for such determination and (y) the number of shares of our common stock issuable pursuant to such rights or warrants; and

•

the denominator of which shall be the sum of (i) the number of shares of common stock outstanding immediately prior to 5:00 p.m., New York City time, on the date fixed for such determination and (ii) the number of shares of common stock equal to the quotient of the aggregate offering price payable to exercise such rights or warrants, divided by the current market price of our common stock.

Any increase made pursuant to this clause (2) will become effective immediately after 5:00 p.m., New York City time, on the date fixed for such determination. In the event that such rights or warrants described in this clause (2) are not so issued, each fixed conversion rate shall be decreased, effective as of the date our board of directors, or an authorized committee thereof, publicly announces its decision not to issue such rights or warrants, to such fixed conversion rate that would then be in effect if such issuance had not been declared. To the extent that such rights or warrants are not exercised prior to their expiration or shares of our common stock are otherwise not delivered pursuant to such rights or warrants upon the exercise of such rights or warrants, each fixed conversion rate shall be decreased to such fixed conversion rate that would then be in effect had the increase made upon the issuance of such rights or warrants been made on the basis of the delivery of only the number of shares of our common stock actually delivered. In determining whether any rights or warrants entitle the holders thereof to subscribe for or purchase shares of our common stock at less than the current market price, and in determining the aggregate offering price payable to exercise such rights or warrants, there shall be taken into account any consideration received by us for such rights or warrants and the amount payable to us upon exercise or conversion thereof, the value of such consideration (if other than cash) to be determined by our board of directors, or an authorized committee thereof. For the purposes

S-51

of this clause (2), the number of shares of common stock at the time outstanding shall not include shares held in treasury but shall include any shares issuable in respect of any scrip certificates issued in lieu of fractions of shares of common stock. We will not issue any such rights or warrants in respect of shares of common stock held in treasury.

(3)	We subdivide or combine our common stock, in which event each fixed conversion rate in effect immediately prior to 9:00 a.m., New York City time, on the effective date of such subdivision or combination will be multiplied by a fraction:

•

the numerator of which is the number of shares of our common stock that would be outstanding immediately after, and solely as a result of, such subdivision or combination; and

•

the denominator of which is the number of shares of our common stock outstanding immediately prior to such subdivision or combination.

Any adjustment made pursuant to this clause (3) shall become effective immediately after 9:00 a.m., New York City time, on the effective date of such subdivision or combination.

(4)

We distribute to all or substantially all holders of our common stock evidences of our indebtedness, shares of capital stock, securities, rights to acquire our capital stock (other than rights issued pursuant to a stockholders’ rights plan so long as such rights have not separated from the common stock), cash or other assets, excluding:

•

any dividend or distribution as to which an adjustment was effected pursuant to clause (1) above;

•

any rights or warrants as to which an adjustment was effected pursuant to clause (2) above;

•

any dividend or distribution as to which the provisions set forth in clause (5) below shall apply; and

•

any spin-off, as to which the provisions set forth below in this clause (4) shall apply,

in which event each fixed conversion rate in effect immediately prior to 5:00 p.m., New York City time, on the date fixed for the determination of holders of our common stock entitled to receive such distribution will be multiplied by a fraction:

•

the numerator of which is the current market price of our common stock; and

•

the denominator of which is the current market price of our common stock minus the fair market value, as determined by our board of directors, or an authorized committee thereof, on the “ex-date” (as defined below) of such distribution, of the portion of the evidences of indebtedness, shares of capital stock, securities, rights to acquire our capital stock, cash or other assets so distributed applicable to one share of our common stock.

Any increase made pursuant to the preceding paragraph will become effective immediately after 5:00 p.m., New York City time, on the date fixed for such determination. In the event that such distribution described in the preceding paragraph is not so made, each fixed conversion rate shall be decreased, effective as of the date our board of directors, or an authorized committee thereof, publicly announces its decision not to make such distribution, to such fixed conversion rate that would then be in effect if such distribution had not been declared.

In the event that we make a distribution to all holders of our common stock consisting of capital stock of, or similar equity interests in, or relating to a subsidiary or other business unit of ours, that are, or, when issued, will be, listed or admitted for trading on a U.S. national securities exchange (herein referred to as a “spin-off”), each fixed conversion rate in effect immediately prior to 9:00 a.m., New York City time, on the ex-date of such distribution will be multiplied by a fraction:

•

the numerator of which is the sum of the current market price of our common stock and the current market price of the portion of those shares of capital stock or similar equity interests so distributed applicable to one share of common stock, and

•

the denominator of which is the current market price of our common stock.

S-52

Any increase made pursuant to the preceding paragraph shall be made immediately following the determination of the current market price of our common stock, but shall become retroactively effective immediately after 9:00 a.m., New York City time, on the ex-date of such distribution. In the event that such distribution described in the preceding paragraph is not so made, each fixed conversion rate shall be decreased, effective as of the date our board of directors, or an authorized committee thereof, publicly announces its decision not to make such distribution, to such fixed conversion rate that would then be in effect if such distribution had not been declared. Because we will make any increase to each fixed conversion rate pursuant to the preceding paragraph with retroactive effect, we will delay the settlement of any conversion of Mandatory Convertible Preferred Stock where any date for determining the number of shares of our common stock issuable upon such conversion occurs during the period for determining the current market price pursuant to the preceding paragraph until the second business day immediately following the last trading day of such period.

(5)	We make a dividend or distribution consisting exclusively of cash to all or substantially all holders of our common stock, excluding:

•

any cash that is distributed in exchange for our common stock in a reorganization event (as described below),

•

any dividend or distribution in connection with our liquidation, winding-up or dissolution, and

•

any consideration payable as part of a tender or exchange offer covered by clause (6),

in which event, each fixed conversion rate in effect immediately prior to 5:00 p.m., New York City time, on the date fixed for determination of the holders of our common stock entitled to receive such dividend or distribution will be multiplied by a fraction:

•

the numerator of which is the current market price of our common stock, and

•

the denominator of which is the current market price of our common stock minus the amount per share of our common stock of such dividend or distribution.

Any increase made pursuant to this clause (5) shall become effective immediately after 5:00 p.m., New York City time, on the date fixed for the determination of the holders of our common stock entitled to receive such dividend or distribution. In the event that any dividend or distribution described in this clause (5) is not so made, each fixed conversion rate shall be decreased, effective as of the date our board of directors, or an authorized committee thereof, publicly announces its decision not to make such dividend or distribution, to such fixed conversion rate which would then be in effect if such dividend or distribution had not been declared.

(6)

We or any of our subsidiaries successfully complete a tender or exchange offer pursuant to a Schedule TO or registration statement on Form S-4 for our common stock where the cash and the value of any other consideration included in the payment per share of our common stock exceeds the current market price of our common stock, in which event each fixed conversion rate in effect immediately prior to 5:00 p.m., New York City time, on the date of expiration of the tender or exchange offer (the “expiration date”) will be multiplied by a fraction:

•

the numerator of which shall be equal to the sum of:

(i)

the aggregate cash and fair market value (as determined by our board of directors, or an authorized committee thereof) on the expiration date of any other consideration paid or payable for shares purchased in such tender or exchange offer; and

(ii)

the product of:

the current market price of our common stock; and

the number of shares of our common stock outstanding immediately after such tender or exchange offer expires (after giving effect to the purchase or exchange of shares pursuant to such tender or exchange offer), and

S-53

•

the denominator of which shall be equal to the product of:

(i)

the current market price of our common stock; and

(ii)

the number of shares of our common stock outstanding immediately prior to the time such tender or exchange offer expires (without giving effect to the purchase or exchange of shares pursuant to such tender or exchange offer).

Any increase made pursuant to this clause (6) shall be made immediately following the determination of the current market price of our common stock, but shall become retroactively effective immediately after 5:00 p.m., New York City time, on the expiration date. In the event that we are, or one of our subsidiaries is, obligated to purchase shares of our common stock pursuant to any such tender offer or exchange offer, but we are, or such subsidiary is, permanently prevented by applicable law from effecting any such purchases, or all such purchases are rescinded, then each fixed conversation rate shall be decreased to be such fixed conversion rate that would then be in effect if such tender offer or exchange offer had not been made. Except as set forth in the preceding sentence, if the application of this clause (6) to any tender offer or exchange offer would result in a decrease in each fixed conversation rate, no adjustment shall be made for such tender offer or exchange offer under this clause (6). Because we will make any increase to each fixed conversion rate pursuant to this clause (6) with retroactive effect, we will delay the settlement of any conversion of Mandatory Convertible Preferred Stock where any date for determining the number of shares of our common stock issuable upon such conversion occurs during the period for determining the current market price pursuant to this clause (6) until the second business day immediately following the last trading day of such period.

In cases where (i) the fair market value of the evidences of our indebtedness, shares of capital stock, securities, rights to acquire our capital stock, cash or other assets distributed per share of our common stock as to which clause (4) above applies (except with respect to a spin-off), or (ii) the amount of cash distributed per share of our common stock as to which clause (5) above applies, in each case, equals or exceeds the average VWAP per share of our common stock over the ten consecutive trading day period ending on, and including, the trading day immediately preceding the ex-date of such distribution, rather than being entitled to an adjustment in each fixed conversion rate, holders of the Mandatory Convertible Preferred Stock will be entitled to receive (without having to convert their Mandatory Convertible Preferred Stock), at the same time and upon the same terms as holders of our common stock, the kind and amount of the evidences of our indebtedness, shares of capital stock, securities, rights to acquire our capital stock, cash or other assets, as the case may be, comprising the distribution that such holder would have received if such holder had owned, immediately prior to the record date for determining the holders of our common stock entitled to receive the distribution, for each share of Mandatory Convertible Preferred Stock, a number of shares of our common stock equal to the maximum conversion rate in effect on the date of such distribution.

To the extent that we have a rights plan in effect with respect to our common stock on any conversion date, upon conversion of any shares of the Mandatory Convertible Preferred Stock, a converting holder will receive, in addition to our common stock, the rights under the rights plan, unless, prior to such conversion date, the rights have separated from our common stock, in which case each fixed conversion rate will be adjusted at the time of separation as if we made a distribution to all holders of our common stock as described in the portion of clause (4) above not relating to a spin-off, subject to readjustment in the event of the expiration, termination or redemption of such rights. Any distribution of rights or warrants pursuant to a rights plan that would allow a holder to receive upon conversion, in addition to any shares of our common stock, the rights described therein (unless such rights or warrants have separated from our common stock (in which case each fixed conversion rate will be adjusted at the time of separation as if we made a distribution to all holders of our common stock as described in the portion of clause (4) above not relating to a spin-off, subject to readjustment in the event of the expiration, termination or redemption of such rights)) shall not constitute a distribution of rights or warrants that would entitle such holder to an adjustment to the fixed conversion rates.

S-54

For the purposes of determining the adjustment to the fixed conversion rate for the purposes of:

•

clause (2), clause (4) in the event of an adjustment not relating to a spin-off and clause (5) above, the “current market price” of our common stock is the average VWAP per share of our common stock over the ten consecutive trading day period ending on, and including, (x) for purposes of clause (2) above, the trading day immediately preceding the announcement date of the relevant issuance and (y) for purposes of clause (4) in the event of an adjustment not relating to a spin-off and clause (5) above, the trading day immediately preceding the ex-date of the relevant distribution;

•

clause (4) above in the event of an adjustment relating to a spin-off, the “current market price” of our common stock, capital stock or similar equity interest, as applicable (in the case of any capital stock or similar equity interest, determined by reference to the definition of “VWAP” as if references therein to our common stock were to such capital stock or similar equity interest), is the average VWAP per share over the first ten consecutive trading days commencing on, and including, the ex-date of such distribution; and

•

clause (6) above, the “current market price” of our common stock is the average VWAP per share of our common stock over the ten consecutive trading day period commencing on, and including, the trading day immediately following the expiration date of the relevant tender or exchange offer.

The term “ex-date,” when used with respect to any issuance, dividend or distribution, means the first date on which the shares of our common stock trade on the applicable exchange or in the applicable market, regular way, without the right to receive the issuance, dividend or distribution in question, from us or, if applicable, from the seller of our common stock on such exchange or market (in the form of due bills or otherwise) as determined by such exchange or market.

In addition, we may make such increases in each fixed conversion rate as we deem advisable if our board of directors, or an authorized committee thereof, determines that such increase would be in our best interest or in order to avoid or diminish any income tax to holders of our common stock resulting from any dividend or distribution of shares of our common stock (or issuance of rights or warrants to acquire shares of our common stock) or from any event treated as such for income tax purposes or for any other reason. We may only make such a discretionary adjustment if we make the same proportionate adjustment to each fixed conversion rate.

Beneficial owners of the Mandatory Convertible Preferred Stock or the Depositary Shares may, in certain circumstances, including a taxable distribution to holders of our common stock or an increase in each fixed conversion rate in our discretion, be deemed to have received a distribution subject to U.S. federal income tax as a dividend as a result of an adjustment or the non-occurrence of an adjustment to the fixed conversion rates. In addition, any deemed distribution to Non-U.S. Holders (as defined in the section titled “Material U.S. Federal Income Tax Consequences”) of the Mandatory Convertible Preferred Stock or the Depositary Shares may, in certain circumstances, be subject to U.S. federal withholding tax requirements. See the section titled “Material U.S. Federal Income Tax Consequences.”

If we (or an applicable withholding agent) are required to withhold on deemed distributions to a holder of the Mandatory Convertible Preferred Stock or the Depositary Shares (see the section titled “Material U.S. Federal Income Tax Consequences”) and pay the applicable withholding taxes, we may, at our option, or an applicable withholding agent may, withhold such taxes from payments of cash or shares of common stock payable to, sales proceeds subsequently paid or credited to, or other funds or assets of, such holder.

Adjustments to the fixed conversion rates will be calculated to the nearest 1/10,000th of a share. Prior to the first trading day of the final averaging period, no adjustment to a fixed conversion rate will be required unless the adjustment would require an increase or decrease of at least one percent in such fixed conversion rate. If any adjustment is not required to be made because it would not change the fixed conversion rates by at least one percent, then the adjustment will be carried forward and taken into account in any subsequent adjustment; provided, however, that we will make such adjustments, regardless of whether such aggregate adjustments

S-55

amount to one percent or more of the fixed conversion rates (x) on any early conversion date (including in connection with a fundamental change); (y) on the effective date of any fundamental change; and (z) on each trading day of the final averaging period.

No adjustments to the fixed conversion rates will be made if holders may participate (other than in the case of (x) a share subdivision or share combination or (y) a tender or exchange offer), at the same time, upon the same terms and otherwise on the same basis as holders of our common stock and solely as a result of holding Mandatory Convertible Preferred Stock, in the transaction that would otherwise give rise to such adjustment without having to convert their Mandatory Convertible Preferred Stock and as if they held, for each share of Mandatory Convertible Preferred Stock, a number of shares of our common stock equal to the maximum conversion rate then in effect.

The fixed conversion rates will not be adjusted except as provided above. Without limiting the foregoing, the fixed conversion rates will not be adjusted:

(a)

upon the issuance of any common stock (or rights with respect thereto) pursuant to any present or future plan providing for the reinvestment of dividends or interest payable on our securities and the investment of additional optional amounts in common stock under any plan;

(b)

upon the issuance of any common stock or rights or warrants to purchase those shares pursuant to any present or future employee, director or consultant benefit or other incentive plan or program of or assumed by us or any of our subsidiaries;

(c)

upon the issuance of any common stock pursuant to any option, warrant, right or exercisable, exchangeable or convertible security outstanding as of the initial issue date;

(d)

for a change solely in the par value of our common stock;

(e)

for sales of our common stock for cash, including the sale of shares of our common stock for a purchase price that is less than the applicable market price per share of our common stock or less than the initial price or the threshold appreciation price, other than in a transaction described in clause (2) or clause (4) above;

(f)

for stock repurchases that are not tender or exchange offers, including pursuant to structured or derivative transactions;

(g)

as a result of a tender offer solely to holders of fewer than 100 shares of our common stock;

(h)

as a result of a third-party tender or exchange offer, other than a tender or exchange offer by one of our subsidiaries as described in clause (6) above; or

(i)

for accumulated and unpaid dividends on the Mandatory Convertible Preferred Stock, except as described above under the section titled “—Mandatory Conversion,” “—Conversion at the Option of the Holder” and “—Conversion at the Option of the Holder upon Fundamental Change; Fundamental Change Dividend Make-Whole Amount.”

We will, as soon as practicable after the fixed conversion rates are adjusted, provide, or cause to be provided, written notice of the adjustment to the holders of shares of Mandatory Convertible Preferred Stock. We will also upon written request by a beneficial owner of the Depositary Shares deliver a statement setting forth in reasonable detail the method by which the adjustment to each fixed conversion rate was determined and setting forth each revised fixed conversion rate.

If an adjustment is made to the fixed conversion rates, an inversely proportional adjustment also will be made to the floor price. For the avoidance of doubt, if an adjustment is made to the fixed conversion rates, no separate inversely proportionate adjustment will be made to the initial price or the threshold appreciation price because the initial price is equal to $1,000 divided by the maximum conversion rate (as adjusted in the manner described herein) and the threshold appreciation price is equal to $1,000 divided by the minimum conversion rate (as adjusted in the manner described herein).

S-56

Whenever any provision of the certificate of designations establishing the terms of the Mandatory Convertible Preferred Stock requires us to calculate the VWAP per share of our common stock over a span of multiple days, our board of directors, or any authorized committee thereof, will make appropriate adjustments (including, without limitation, to the applicable market value, the early conversion average price, the stock price and the five-day average price, as the case may be) to account for any adjustments to the fixed conversion rates that become effective, or any event that would require such an adjustment if the record date, ex-date, effective date or expiration date, as the case may be, of such event occurs, during the relevant period used to calculate such prices or values, as the case may be.

If:

•

the record date for a dividend or distribution on our common stock occurs after the end of the final averaging period and before the mandatory conversion date, and

•

that dividend or distribution would have resulted in an adjustment of the number of shares of our common stock issuable to the holders of Mandatory Convertible Preferred Stock had such record date occurred on or before the last trading day of the final averaging period,

then we will deem the holders of Mandatory Convertible Preferred Stock to be holders of record, for each share of Mandatory Convertible Preferred Stock that they hold, of a number of shares of our common stock equal to the conversion rate for purposes of that dividend or distribution. In this case, the holders of the Mandatory Convertible Preferred Stock would receive the dividend or distribution on our common stock together with the number of shares of common stock issuable upon mandatory conversion of the Mandatory Convertible Preferred Stock.

Recapitalizations, Reclassifications and Changes in our Common Stock

In the event of:

•

any consolidation or merger of us with or into another person (other than a merger or consolidation in which we are the continuing corporation and in which the shares of our common stock outstanding immediately prior to the merger or consolidation are not exchanged for cash, securities or other property of us or another person);

•

any sale, transfer, lease or conveyance to another person of all or substantially all of our and our subsidiaries’ consolidated property and assets;

•

any reclassification of our common stock into securities, including securities other than our common stock; or

•

any statutory exchange of our securities with another person or binding share exchange (other than in connection with a merger or consolidation),

in each case, as a result of which our common stock would be converted into, or exchanged for, securities, cash or property (each, a “reorganization event”), each share of Mandatory Convertible Preferred Stock outstanding immediately prior to such reorganization event shall, without the consent of the holders of the Mandatory Convertible Preferred Stock, become convertible into the kind of securities, cash and other property that such holder would have been entitled to receive if such holder had converted its Mandatory Convertible Preferred Stock into common stock immediately prior to such reorganization event (such securities, cash and other property, the “exchange property,” with each “unit of exchange property” meaning the kind and amount of exchange property that a holder of one share of common stock is entitled to receive). For purposes of the foregoing, the type and amount of exchange property in the case of any reorganization event that causes our common stock to be converted into the right to receive more than a single type of consideration (determined based in part upon any form of stockholder election) will be deemed to be the weighted average of the types and amounts of consideration actually received by the holders of our common stock in such reorganization event. We

S-57

will notify holders of the Mandatory Convertible Preferred Stock of such weighted average as soon as practicable after such determination is made. The number of units of exchange property we will deliver upon conversion of each share of Mandatory Convertible Preferred Stock or as a payment of dividends on the Mandatory Convertible Preferred Stock, as applicable, following the effective date of such reorganization event will be determined as if references to our common stock in the description of the conversion rate applicable upon mandatory conversion, conversion at the option of the holder or conversion at the option of the holder upon a fundamental change and/or the description of the relevant dividend payment provisions, as applicable, were to units of exchange property (without interest thereon and without any right to dividends or distributions thereon which have a record date prior to the date on which holders of the Mandatory Convertible Preferred Stock become holders of record of the underlying exchange property). For the purpose of determining which bullet of the definition of conversion rate will apply upon mandatory conversion, and for the purpose of calculating the conversion rate if the second bullet of such definition is applicable, the value of a unit of exchange property will be determined in good faith by our board of directors, or an authorized committee thereof, except that if a unit of exchange property includes common stock or ADRs that are traded on a U.S. national securities exchange, the value of such common stock or ADRs will be the average over the final averaging period of the volume-weighted average prices for such common stock or ADRs, as displayed on the applicable Bloomberg screen (as determined in good faith by our board of directors, or an authorized committee thereof), or, if such price is not available, the average market value per share of such common stock or ADRs over such period as determined, using a volume-weighted average method, by a nationally recognized independent investment banking firm retained by us for this purpose, which may include any of the underwriters for this offering. We (or any successor to us) will, as soon as reasonably practicable (but in any event within 20 calendar days) after the occurrence of any reorganization event, provide written notice to the holders of Mandatory Convertible Preferred Stock of such occurrence and of the kind and amount of cash, securities or other property that constitute the exchange property. Failure to deliver such notice will not affect the operation of the provisions described in this section.

Reservation of Shares

We will at all times reserve and keep available out of the authorized and unissued common stock or shares of common stock held in treasury by us, solely for issuance upon conversion of the Mandatory Convertible Preferred Stock, free from any preemptive or other similar rights, the maximum number of shares of common stock as shall be issuable from time to time upon the conversion of all the shares of Mandatory Convertible Preferred Stock then outstanding (including, for the avoidance of doubt, the maximum additional conversion amount).

Transfer Agent, Conversion Agent, Paying Agent and Registrar

Computershare Trust Company, N.A. is the transfer agent, conversion agent, paying agent and registrar for the Mandatory Convertible Preferred Stock.

DESCRIPTION OF DEPOSITARY SHARES

We will deposit the shares of the Mandatory Convertible Preferred Stock, represented by the Depositary Shares offered hereby pursuant to a deposit agreement (the “deposit agreement”) to be dated as of the closing date of this offering, among us, Computershare Trust Company, N.A. and Computershare Inc., acting jointly as bank depositary (the “bank depositary”), and the holders from time to time of the Depositary Shares.

The following description is a summary of the material provisions of the Depositary Shares and the deposit agreement and does not purport to be complete. The terms of the Depositary Shares include those expressly set forth in the deposit agreement, and this summary is subject to and is qualified by reference to all the provisions of the Depositary Shares and the deposit agreement, including the definitions of certain terms used in the deposit agreement.

You may request a copy of the deposit agreement from us as described under the section titled “Where You Can Find More Information” in the accompanying prospectus. We urge you to read this document because it, and not this description, defines your rights as a holder of Depositary Shares.

For purposes of this description, references to “we,” “our” and “us” refer only to Super Micro Computer, Inc. and not to its subsidiaries.

This “Description of Depositary Shares” section supplements and, to the extent inconsistent therewith, supersedes the information in the accompanying prospectus under the caption “Description of Depositary Shares.”

General

Each Depositary Share represents a 1/20th interest in a share of our Mandatory Convertible Preferred Stock and will initially be evidenced by a global security, as defined in and described under the section titled “—Book-Entry, Settlement and Clearance” in this section. Subject to the terms of the deposit agreement, the Depositary Shares will be entitled to all special rights, preferences, privileges and voting powers of our Mandatory Convertible Preferred Stock (including conversion, dividend, voting and liquidation rights), as applicable, in proportion to the fraction of a share of our Mandatory Convertible Preferred Stock those Depositary Shares represent.

In this section, references to “holders” of Depositary Shares mean those who have Depositary Shares registered in their own names on the books maintained by the bank depositary and not indirect holders who will own beneficial interests in Depositary Shares registered in the street name of, or issued in book-entry form through, DTC prior to the mandatory conversion of our Mandatory Convertible Preferred Stock. You should review the special considerations that apply to indirect holders as described under the section titled “—Book-Entry, Settlement and Clearance” in this section.

Transfer Agent, Registrar, Conversion Agent and Paying Agent

The bank depositary will act as the initial transfer agent, registrar, conversion agent and paying agent for the Depositary Shares. However, without prior notice to the holders of the Depositary Shares, we may change the transfer agent, registrar, paying agent and conversion agent and we or any of our subsidiaries may choose to act in that capacity as well (except that the transfer agent, registrar, paying agent or conversion agent with respect to any Depositary Shares represented by a “global security” (as defined below under the caption “—Book-Entry, Settlement and Clearance—The Global Security”) in global form must at all times be a person that is eligible to act in that capacity under the applicable depositary procedures.

Transfers and Exchanges

A holder of Depositary Shares may transfer or exchange its Depositary Shares at the office of the registrar in accordance with the deposit agreement. We, the transfer agent and the registrar may require the holder to, among

S-59

other things, deliver appropriate endorsements or transfer instruments as we or they may reasonably require. In addition, subject to the terms of the deposit agreement, we, the transfer agent and the registrar may refuse to register the transfer or exchange of any Depositary Share that is subject to conversion.

Deposit of Mandatory Convertible Preferred Stock

We will deposit the Mandatory Convertible Preferred Stock in which the Depositary Shares we are offering represent undivided interests with the bank depositary pursuant to the deposit agreement. For each share of such Mandatory Convertible Preferred Stock deposited with the bank depositary, we will cause there to be issued 20 Depositary Shares pursuant to the deposit agreement. Each Depositary Share will represent a 1/20th undivided interest in a share of Mandatory Convertible Preferred Stock that is on deposit with the bank depositary. Accordingly, although the bank depositary will be the registered holder of such Mandatory Convertible Preferred Stock, holders of the Depositary Shares will have proportional fractional interests in the rights and preferences of such Mandatory Convertible Preferred Stock (including conversion, dividend, voting and liquidation rights), subject to the terms of the deposit agreement.

If any share of Mandatory Convertible Preferred Stock on deposit with the bank depositary ceases to be outstanding a result of its conversion, then, from and after such cessation, the Depositary Shares formerly representing such share of Mandatory Convertible Preferred Stock will represent only the right to receive the consideration due upon such conversion pursuant to the deposit agreement.

Conversion

Because each Depositary Share represents a 1/20th interest in a share of our Mandatory Convertible Preferred Stock, a holder of Depositary Shares may elect to convert Depositary Shares only in lots of 20 Depositary Shares, either on an early conversion date at the minimum conversion rate of shares of our common stock per Depositary Share, subject to adjustment, or during a fundamental change conversion period at the fundamental change conversion rate, as described below. For a description of the terms and conditions on which our Mandatory Convertible Preferred Stock is convertible at the option of holders of Mandatory Convertible Preferred Stock, see the sections titled “Description of Mandatory Convertible Preferred Stock—Conversion at the Option of the Holder” and “Description of Mandatory Convertible Preferred Stock—Conversion at the Option of the Holder upon Fundamental Change; Fundamental Change Dividend Make-Whole Amount” in this prospectus supplement.

The following table sets forth the fundamental change conversion rate per Depositary Share, subject to adjustment as described under the section titled “Description of Mandatory Convertible Preferred Stock—Conversion at the Option of the Holder upon Fundamental Change; Fundamental Change Dividend Make-Whole Amount,” based on the effective date of the fundamental change and the stock price in the fundamental change:

Stock Price

Effective Date

June , 2026

June 1, 2027

June 1, 2028

June 1, 2029

The exact stock price and effective date may not be set forth in the table, in which case:

•

if the stock price is between two stock prices on the table or the effective date is between two effective dates on the table, the fundamental change conversion rate per Depositary Share will be determined by straight-line interpolation between the fundamental change conversion rates per Depositary Share set forth for the higher and lower stock prices and the earlier and later effective dates, as applicable, based on a 365-day or 366-day year, as applicable;

S-60

•

if the stock price is in excess of $ per share (subject to adjustment in the same manner as the column headings of the table above are adjusted pursuant to the provision described in the second paragraph under the section titled “Description of Mandatory Convertible Preferred Stock—Conversion at the Option of the Holder upon Fundamental Change; Fundamental Change Dividend Make-Whole Amount—Fundamental Change Conversion Rate”), then the fundamental change conversion rate per Depositary Share will be the minimum conversion rate, divided by 20; and

•

if the stock price is less than $ per share (subject to adjustment in the same manner as the column headings of the table above are adjusted pursuant to the provision described in the second paragraph under the section titled “Description of Mandatory Convertible Preferred Stock—Conversion at the Option of the Holder upon Fundamental Change; Fundamental Change Dividend Make-Whole Amount—Fundamental Change Conversion Rate”), then the fundamental change conversion rate per Depositary Share will be the maximum conversion rate, divided by 20.

On any conversion date for our Mandatory Convertible Preferred Stock, each Depositary Share corresponding to the shares of our Mandatory Convertible Preferred Stock so converted will be entitled to receive 1/20th of the number of shares of our common stock and the amount of any cash received by the bank depositary upon conversion of each share of our Mandatory Convertible Preferred Stock.

The following table illustrates the conversion rate per Depositary Share, subject to adjustment as described under the section titled “Description of Mandatory Convertible Preferred Stock—Anti-Dilution Adjustments” in this prospectus supplement, based on the applicable market value of our common stock:

LOGO

After delivery of our common stock by the transfer agent to the bank depositary following conversion of our Mandatory Convertible Preferred Stock, the bank depositary will transfer the proportional number of shares of our common stock to the holders of Depositary Shares by book-entry transfer through DTC or, if the holders’ interests are in certificated depositary receipts, by delivery of common stock certificates for such number of shares of our common stock.

If we (or an applicable withholding agent) are required to withhold on distributions of common stock in respect of dividends in arrears or in respect of the present value of future dividends to a holder of the Mandatory Convertible Preferred Stock or the Depositary Shares (see the section titled “Material U.S. Federal Income Tax Consequences”) and pay the applicable withholding taxes, we may, at our option, or an applicable withholding agent may, withhold such taxes from payments of cash or shares of common stock payable to, sales proceeds subsequently paid or credited to, or other funds or assets of, such holder.

Fractional Shares

No fractional shares of common stock will be issued to holders of our Depositary Shares upon conversion. In lieu of any fractional shares of common stock otherwise issuable in respect of the aggregate number of Depositary Shares of any holder that are converted, that holder will be entitled to receive an amount in cash (computed to the nearest cent) equal to the product of: (i) that same fraction; and (ii) the average VWAP per share of our common stock over the five consecutive trading day period ending on, and including, the second trading day immediately preceding the conversion date.

S-61

If more than one Depositary Share is surrendered for, or subject to, conversion at one time by or for the same holder, the number of shares of our common stock issuable upon conversion thereof shall be computed on the basis of the aggregate number of Depositary Shares so surrendered for, or subject to, conversion.

Dividends and Other Distributions

Each dividend paid on a Depositary Share will be in an amount equal to 1/20th of the dividend paid on the related share of our Mandatory Convertible Preferred Stock. So long as our Depositary Shares are held of record by the nominee of DTC, declared cash dividends in respect of our Depositary Shares will be paid to DTC in same-day funds on each dividend payment date. DTC will credit accounts of its participants in accordance with DTC’s normal procedures. The participants will be responsible for holding or disbursing such payments to beneficial owners of our Depositary Shares in accordance with the instructions of such beneficial owners.

The bank depositary will deliver any cash or shares of common stock it receives in respect of dividends on our Mandatory Convertible Preferred Stock to the holders of the Depositary Shares in such amounts as are, as nearly as practicable, in proportion to the number of outstanding Depositary Shares held by such holders, on the date of receipt or as soon as practicable thereafter.

The amount due on the Depositary Shares on the first dividend payment date for the Mandatory Convertible Preferred Stock, if declared, is expected to be $ per Depositary Share, and the amount due on each subsequent dividend payment date for the Mandatory Convertible Preferred Stock, if declared, is expected to be $ per Depositary Share.

Record dates for distributions or payments on the Depositary Shares will be the same as the corresponding record dates for our Mandatory Convertible Preferred Stock.

No fractional shares of common stock will be delivered to the holders of our Depositary Shares in respect of dividends payable on the Mandatory Convertible Preferred Stock. Each holder that would otherwise be entitled to a fraction of a share of common stock will instead be entitled to receive a cash adjustment (computed to the nearest cent) based on the average VWAP per share of our common stock over the five consecutive trading day period ending on, and including, the second trading day immediately preceding the applicable dividend payment date.

The amount paid as dividends or otherwise distributable by the bank depositary with respect to the Depositary Shares or the underlying Mandatory Convertible Preferred Stock will be reduced by any amounts required to be withheld by us or the bank depositary on account of taxes or other governmental charges. The bank depositary may refuse to make any payment or distribution, or any transfer, exchange, or withdrawal of any Depositary Shares or the shares of our Mandatory Convertible Preferred Stock until such taxes or other governmental charges are paid.

No Redemption

We may not redeem our Depositary Shares. However, at our option, we may purchase our Depositary Shares from time to time in the open market, by tender offer, exchange offer or otherwise.

Voting the Mandatory Convertible Preferred Stock

Because each Depositary Share represents a 1/20th interest in a share of the Mandatory Convertible Preferred Stock, holders of depositary receipts will be entitled to 1/20th of a vote per share of Mandatory Convertible Preferred Stock under those circumstances in which holders of the Mandatory Convertible Preferred Stock are entitled to a vote, as described under the section titled “Description of Mandatory Convertible Preferred Stock—Voting Rights” in this prospectus supplement.

S-62

When the bank depositary receives notice of any meeting at which the holders of our Mandatory Convertible Preferred Stock are entitled to vote, the bank depositary will as soon as practicable send a copy of such notice to the record holders of the Depositary Shares relating to the Mandatory Convertible Preferred Stock. Each record holder of Depositary Shares on the record date (which will be the same date as the record date for our Mandatory Convertible Preferred Stock) may instruct the bank depositary as to how to vote the amount of our Mandatory Convertible Preferred Stock represented by such holder’s Depositary Shares in accordance with these instructions. The bank depositary will endeavor, insofar as practicable, to vote the amount of the preferred stock represented by such Depositary Shares in accordance with these instructions, and we will take all actions the bank depositary deems necessary in order to enable the bank depositary to do so. The bank depositary will abstain from voting shares of the Mandatory Convertible Preferred Stock to the extent it does not receive specific instructions from the holders of Depositary Shares representing our Mandatory Convertible Preferred Stock.

Modification, Amendment and Termination

Without the consent of the holders of the Depositary Shares, we may amend, alter or supplement the deposit agreement or any certificate representing the Depositary Shares for the following purposes:

•

to cure any ambiguity, omission, inconsistency or mistake in any such agreement or instrument;

•

to make any provision with respect to matters or questions relating to the Depositary Shares that is not inconsistent with the provisions of the deposit agreement and that does not materially and adversely affect the rights, preferences, privileges or voting powers of any holder of the Depositary Shares;

•

to make any change reasonably necessary, in our reasonable determination, to reflect each Depositary Share’s representation of 1/20th of a share of our Mandatory Convertible Preferred Stock;

•

to make any change reasonably necessary, in our reasonable determination, to comply with the procedures of the bank depositary and that does not materially and adversely affect the rights, preferences, privileges or voting powers of any holder of the Depositary Shares; or

•

to make any other change that does not materially and adversely affect the rights, preferences, privileges or voting powers of any holder of the Depositary Shares (other than any holder that consents to such change).

In addition, without the consent of the holders of the Depositary Shares, we may amend, alter, supplement or repeal any terms of the Depositary Shares to conform the terms of the Depositary Shares to the description thereof in the accompanying prospectus as supplemented and/or amended by the section titled “Description of Depositary Shares” and the section titled “Description of Mandatory Convertible Preferred Stock,” as further supplemented and/or amended by the related pricing term sheet.

With the consent of the record holders of at least a majority of the aggregate number of Depositary Shares then outstanding, the Depositary Shares and any provisions of the deposit agreement may at any time and from time to time be amended, altered or supplemented by agreement between us and the bank depositary; provided that, without the consent of each record holder of an outstanding Depositary Share affected, no such amendment, alteration or supplement will:

•

reduce the number of Depositary Shares the record holders of which must consent to an amendment, alteration or supplement of the Depositary Shares or the deposit agreement;

•

reduce the amount payable or deliverable in respect of the Depositary Shares or extend the stated time for such payment or delivery;

•

impair the right, subject to certain requirements set forth in the deposit agreement, of any owner of Depositary Shares to surrender any receipt evidencing such Depositary Shares to the bank depositary with instructions to deliver to it the Mandatory Convertible Preferred Stock and all money and/or other property represented thereby;

S-63

•

change the currency in which payments in respect of the Depositary Shares or any receipt evidencing such Depositary Shares is made;

•

impair the right of any record holder of Depositary Shares to receive payments or deliveries on its Depositary Shares on or after the due dates therefor or to institute suit for the enforcement of any such payment or delivery;

•

make any change that materially and adversely affects the conversion rights of any record holder of Depositary Shares; or

•

make any change that materially and adversely affects the voting rights of any record holder of Depositary Shares.

The deposit agreement may be terminated by us or the bank depositary only if (a) all outstanding Depositary Shares have been cancelled, upon conversion of the Mandatory Convertible Preferred Stock or otherwise, or (b) there has been made a final distribution in respect of the Mandatory Convertible Preferred Stock in connection with any liquidation, winding-up or dissolution of us and such distribution shall have been distributed to the record holders of the depositary receipts pursuant to the deposit agreement.

Charges of Bank Depositary

We will pay all transfer and other taxes and governmental charges arising solely from the existence of the depositary arrangements. We will pay charges of the bank depositary in connection with the initial deposit of the Mandatory Convertible Preferred Stock. Except as otherwise set forth in this “Description of Depositary Shares” section, holders of depositary receipts will pay other transfer and other taxes and governmental charges and any other charges, including a fee for the withdrawal of shares of Mandatory Convertible Preferred Stock upon surrender of depositary receipts, as are expressly provided in the deposit agreement to be for their accounts.

Withdrawal Rights

A holder of 20 Depositary Shares may withdraw the share of our Mandatory Convertible Preferred Stock corresponding to such Depositary Shares, and any cash or other property represented by such Depositary Shares. A holder who withdraws shares of Mandatory Convertible Preferred Stock (and any such cash or other property) will not be required to pay any stock transfer and documentary stamp or similar taxes or duties relating to the issuance or delivery of such shares of Mandatory Convertible Preferred Stock (and any such cash or other property), except that such holder will be required to pay any such tax or duty that may be payable relating to any transfer involved in the issuance or delivery of such shares of Mandatory Convertible Preferred Stock (and any such cash or other property) in a name other than the name of such holder. Holders of shares of our Mandatory Convertible Preferred Stock will not have the right under the deposit agreement to deposit such shares with the bank depositary in exchange for Depositary Shares.

Listing

We intend to apply to list the Depositary Shares on the Nasdaq Global Select Market under the symbol “SMCIP”. No assurance can be given that our Depositary Shares will be listed or that any such application for listing will be approved. In addition, upon listing, we have agreed to use our reasonable best efforts to keep the Depositary Shares representing fractional interests in the Mandatory Convertible Preferred Stock listed on the Nasdaq Global Select Market. Listing the Depositary Shares on the Nasdaq Global Select Market does not guarantee that a trading market will develop or, if a trading market does develop, the depth of that market or the ability of holders to sell their Depositary Shares easily. We do not expect there will be any separate public trading market for the shares of the Mandatory Convertible Preferred Stock except as represented by the Depositary Shares.

S-64

Form and Notices

The Mandatory Convertible Preferred Stock will be issued in registered form to the bank depositary, and the Depositary Shares will be issued in book-entry only form through DTC prior to the conversion of the Mandatory Convertible Preferred Stock, as described under the section titled “—Book-Entry, Settlement and Clearance” in this section. The bank depositary will forward to the holders of Depositary Shares all reports, notices and communications from us that are delivered to the bank depositary and that we are required to furnish to the holders of our Mandatory Convertible Preferred Stock.

Book-Entry, Settlement and Clearance

The Global Security

The Depositary Shares will initially be represented by a single registered security in global form (the “global security”). Upon issuance, the global security will be deposited with the bank depositary as custodian for DTC and registered in the name of Cede & Co., as nominee of DTC.

You may hold your interests in the global security through DTC, either as a participant in DTC or indirectly through organizations which are participants in DTC. We expect that under procedures established by DTC:

•

upon deposit of the global security with DTC’s custodian, DTC will credit portions of the global security to the accounts of the DTC participants designated by the underwriters; and

•

ownership of beneficial interests in the global security will be shown on, and transfer of ownership of those interests will be effected only through, records maintained by DTC (with respect to interests of DTC participants) and the records of DTC participants (with respect to other owners of beneficial interests in the global security).

Beneficial interests in the global security may not be exchanged for securities in physical, certificated form except in the limited circumstances described below.

Book-Entry Procedures for the Global Security

All interests in the global security will be subject to the operations and procedures of DTC. We have obtained the information in this section or in the accompanying prospectus concerning DTC and its book-entry systems and procedures from sources that we believe to be reliable. We take no responsibility for an accurate portrayal of this information. In addition, the description of the clearing systems in this section reflects our understanding of the rules and procedures of DTC as they are currently in effect. Those systems could change their rules and procedures at any time.

DTC has provided us the following information: DTC is a limited-purpose trust company organized under the laws of the State of New York, a “banking organization” within the meaning of the New York Banking Law, a member of the Federal Reserve System, a “clearing corporation” within the meaning of the New York Uniform Commercial Code and a “clearing agency” registered pursuant to the provisions of Section 17A of the Exchange Act.

DTC holds and provides asset servicing for U.S. and non-U.S. equity, corporate and municipal debt issues and money market instruments that DTC’s participants, referred to as “direct DTC participants,” deposit with DTC. DTC also facilitates the post-trade settlement among direct participants of sales and other securities transactions in deposited securities through electronic computerized book-entry transfers and pledges between direct participants’ accounts, thereby eliminating the need for physical movement of certificates. Direct DTC participants include both U.S. and non-U.S. securities brokers and dealers, banks, trust companies, clearing corporations and certain other organizations. DTC is a wholly owned subsidiary of The Depository Trust & Clearing Corporation, which is owned, in part, by a number of direct DTC participants. Indirect access to the DTC system is also available to others, referred to as “indirect DTC participants,” for example, securities brokers and dealers, banks, trust companies and clearing corporations, that clear through or maintain a custodial relationship with a direct DTC participant, either directly or indirectly. DTC rules applicable to direct and indirect participants are on file with the SEC.

S-65

So long as DTC or its nominee is the registered owner of the global security, DTC or such nominee will be considered the sole owner and holder of the Depositary Shares represented by the global security for all purposes under the deposit agreement. Except as provided below, owners of beneficial interests in the global security will not be entitled to have securities represented by the global security registered in their names, will not receive or be entitled to receive physical delivery of the securities under the deposit agreement in definitive form and will not be considered the owners or holders of the securities under the deposit agreement, including for purposes of receiving any reports delivered by us or the bank depositary under the deposit agreement. Accordingly, each person owning a beneficial interest in the global security must rely on the procedures of DTC or its nominee and, if such person is not a participant, on the procedures of the participant through which such person owns its interest, in order to exercise any rights of a holder of securities under the deposit agreement.

Payments of dividends with respect to the Depositary Shares represented by the global security will be made by the bank depositary to DTC or its nominee, as the case may be, as the registered owner of the global security. Neither we nor the bank depositary will have any responsibility or liability for any aspect of the records relating to or payments made on account of beneficial interests in the global security or for maintaining, supervising or reviewing any records relating to those beneficial interests.

We expect that DTC or its nominee, upon receipt of any payment of principal or interest, will credit the participants’ accounts with payments in amounts proportionate to their respective beneficial interests in the principal amount of the global securities as shown on the records of DTC or its nominee. We also expect that payments by participants to owners of beneficial interests in the global security held through these participants will be governed by standing instructions and customary practices, as is now the case with securities held for the accounts of customers registered in “street name.” The participants are responsible for the standing instructions and customary practices governing beneficial interests.

Transfers between participants in DTC will be effected under DTC’s procedures and will be settled in same-day funds.

Certificated Securities

Individual certificates in respect of the Depositary Shares will be issued in exchange for the global security only if DTC notifies us that it is unwilling or unable to continue as a clearing system in connection with the global security, or ceases to be a clearing agency registered under the Exchange Act, and a successor clearing system is not appointed by us within 90 days after we receive such notice from DTC or upon our becoming aware that DTC is no longer so registered.

S-66

MATERIAL U.S. FEDERAL INCOME TAX CONSEQUENCES

The following is a summary of the material U.S. federal income tax consequences of purchasing, owning, converting and disposing of our Depositary Shares, the shares of our Mandatory Convertible Preferred Stock represented by the Depositary Shares, and the shares of our common stock into which our Mandatory Convertible Preferred Stock may be converted by U.S. Holders (as defined below) and Non-U.S. Holders (as defined below) that acquire Depositary Shares in this offering at the initial offering price, but does not purport to be a complete analysis of all the potential tax considerations relating thereto. This summary is based on the provisions of the Internal Revenue Code of 1986, as amended (the “Code”), applicable U.S. Treasury regulations thereunder, judicial opinions, and administrative rulings and published positions of the U.S. Internal Revenue Service (the “IRS”), each as in effect as of the date of this prospectus supplement. These authorities are subject to change, possibly on a retroactive basis, and any such change could affect the accuracy of the statements and conclusions set forth in this summary. We have not sought any ruling from the IRS with respect to the statements made and the conclusions reached in the following summary and there can be no assurance that the IRS will agree with such statements and conclusions or that a court would not sustain any challenge by the IRS in the event of litigation.

This summary does not address all aspects of U.S. federal income taxation that may be relevant to holders in light of their particular circumstances, and does not deal with taxes other than U.S. federal income tax (such as estate and gift tax or the Medicare contribution tax on net investment income) or with non-U.S., state, local or other tax considerations. In addition, this summary does not address the application of U.S. federal tax laws to purchasers subject to special tax rules, including:

•

banks, thrifts and other financial institutions;

•

insurance companies;

•

tax-exempt organizations or accounts;

•

regulated investment companies;

•

real estate investment trusts;

•

dealers in securities or currencies;

•

traders in securities that use a mark-to-market method of tax accounting for their securities holdings;

•

persons subject to any alternative minimum tax;

•

U.S. expatriates and certain former citizens or long-term residents of the United States;

•

persons who hold Depositary Shares, our Mandatory Convertible Preferred Stock or our common stock as a position in a hedging transaction, “straddle,” “conversion transaction” or other risk reduction transaction or other integrated transaction;

•

persons deemed to sell Depositary Shares, our Mandatory Convertible Preferred Stock or our common stock under the constructive sale provisions of the Code;

•

“controlled foreign corporations,” “foreign controlled foreign corporations,” “passive foreign investment companies” or corporations that accumulate earnings to avoid U.S. federal income tax;

•

persons required under Section 451(b) of the Code to conform the timing of income accruals with respect to Depositary Shares, our Mandatory Convertible Preferred Stock or our common stock to their financial statements;

•

U.S. Holders who hold Depositary Shares, our Mandatory Convertible Preferred Stock or our common stock through a non-U.S. broker or other non-U.S. intermediary;

•

entities or arrangements treated as a partnership and other pass-through entities for U.S. federal income tax purposes (or a partner or beneficiary thereof);

S-67

•

persons who acquired Depositary Shares, our Mandatory Convertible Preferred Stock or our common stock as compensation or pursuant to the exercise of any employee stock option;

•

“qualified foreign pension funds” as defined in Section 897(l)(2) of the Code and entities all of the interests of which are held by qualified foreign pension funds;

•

tax-qualified retirement plans; and

•

persons who own, or are deemed to own, more than 5% of our common stock.

Such holders should consult their tax advisors to determine the U.S. federal, state, local and non-U.S. tax considerations that may be relevant to them. This summary applies only to holders who hold Depositary Shares, our Mandatory Convertible Preferred Stock and any common stock received upon conversion thereof as “capital assets” within the meaning of Section 1221 of the Code (generally, property held for investment).

Prospective investors should consult their tax advisors regarding the application of U.S. federal tax laws to their particular situations, as well as any tax consequences arising under the laws of any state, local or foreign taxing jurisdiction.

For purposes of this summary, a “U.S. Holder” means a beneficial owner of Depositary Shares, our Mandatory Convertible Preferred Stock or our common stock that is, for U.S. federal income tax purposes, any of the following:

•

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

•

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

•

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

•

a trust if it (1) is subject to the primary supervision of a court within the United States and one or more U.S. persons have the authority to control all substantial decisions of the trust or (2) has a valid election in effect under applicable U.S. Treasury regulations to be treated as a U.S. person.

For purposes of this summary, a “Non-U.S. Holder” means a beneficial owner of Depositary Shares, our Mandatory Convertible Preferred Stock or our common stock that is, for U.S. federal income tax purposes, a person (other than a partnership or other entity or arrangement treated as a partnership) that is not a U.S. Holder.

If an entity or arrangement, domestic or foreign, that is treated as a partnership for U.S. federal income tax purposes, holds Depositary Shares, our Mandatory Convertible Preferred Stock or our common stock, the tax treatment of a partner generally will depend upon the status of the partner and the activities of the partner and the partnership. Prospective investors that are partnerships and partners in such partnerships are urged to consult their tax advisors about the U.S. federal income tax considerations relating to the purchase, ownership, conversion or disposition of Depositary Shares, our Mandatory Convertible Preferred Stock or our common stock.

The discussion below assumes that the representations contained in the deposit agreement are true and that the obligations in the deposit agreement and any related agreement will be complied with in accordance with their terms. Generally, a holder of a Depositary Share should be treated for U.S. federal income tax purposes as holding the fraction of Mandatory Convertible Preferred Stock represented by such Depositary Share. Accordingly, a holder generally should not recognize income, gain, loss or deductions upon a withdrawal of Depositary Shares for shares of Mandatory Convertible Preferred Stock.

Prospective investors are urged to consult their own tax advisors with respect to the application of the U.S. federal income tax laws to their particular situations, as well as any tax consequences of the purchase, ownership,

S-68

conversion and disposition of Depositary Shares, our Mandatory Convertible Preferred Stock and any common stock received upon conversion thereof arising under the U.S. federal estate or gift tax rules or under the laws of any state, local, non-U.S. or other taxing jurisdiction, or under any applicable tax treaty.

Taxation of U.S. Holders

Distributions

Distributions of cash or property that we pay in respect of Depositary Shares, our Mandatory Convertible Preferred Stock or common stock 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) and will be includible in gross income by a U.S. Holder upon receipt. Any such dividend will be eligible for the dividends received deduction (subject to applicable limitations and restrictions) if received by an otherwise qualifying corporate U.S. Holder that meets the holding period and other requirements for the dividends received deduction. Dividends paid to non-corporate U.S. Holders (including individuals) are eligible for U.S. federal income taxation at the rates generally applicable to long-term capital gains for non-corporate U.S. Holders (at a maximum tax rate of 20%), provided that the U.S. Holder receiving the dividend satisfies the applicable holding period and other requirements. To the extent any distribution exceeds our current and accumulated earnings and profits, such excess will be treated as a tax-free return of capital to the extent of the U.S. Holder’s adjusted tax basis in its Depositary Shares, our Mandatory Convertible Preferred Stock, or our common stock (determined separately for each share) which will not be subject to tax, and thereafter will be treated as capital gain (and thus treated in the manner described in the section titled “—Dispositions” below).

We may make distributions to holders of our Mandatory Convertible Preferred Stock, including holders of Depositary Shares, that are paid in shares of our common stock. While not free from doubt, these distributions should be treated for U.S. federal income tax purposes as if the holder received a distribution of cash in an amount equal to the fair market value of the distributed common stock on the date of the distribution and thus should generally be subject to the rules applicable to cash distributions (as discussed above). Accordingly, a U.S. Holder may have a tax liability on account of such distributions in excess of the cash (if any) that is received. Because such distribution may not give rise to any cash from which any applicable withholding tax could be satisfied, if we (or an applicable withholding agent) are required to pay backup withholding on behalf of a U.S. Holder (as further described below under the section titled “—Information Reporting and Backup Withholding”), we (or the applicable withholding agent) could withhold such taxes from shares of common stock or current or subsequent payments of cash to, or other funds or assets of, such U.S. Holder. A U.S. Holder’s initial tax basis in any common stock received as a distribution on the Mandatory Convertible Preferred Stock (or Depositary Shares) will generally equal the fair market value of the common stock on the date of the distribution, and the holding period for that common stock will begin on the day after the distribution.

Adjustments to the Conversion Rate

The conversion rate of the Mandatory Convertible Preferred Stock will be adjusted in certain circumstances. A U.S. Holder that holds our Mandatory Convertible Preferred Stock (or Depositary Shares) may be deemed to have received a constructive distribution if the adjustment has the effect of increasing the U.S. Holder’s proportionate interest in our assets or earnings and profits. In addition, the failure to make certain adjustments to the Mandatory Convertible Preferred Stock may cause a U.S. Holder of our common stock to be deemed to have received a constructive distribution from us, even though the U.S. Holder has not received any cash or property as a result of such failure to make adjustments. Such U.S. Holder would be subject to the rules discussed under the section titled “—Distributions” above. Adjustments to the conversion rate made pursuant to a bona fide reasonable adjustment formula that has the effect of preventing the dilution of the interest of the U.S. Holder of the Mandatory Convertible Preferred Stock (or Depositary Shares), however, will generally not be considered to result in a deemed distribution to the U.S. Holder. Certain of the possible conversion rate adjustments provided in the terms of the Mandatory Convertible Preferred Stock (including adjustments in respect of taxable dividends

S-69

paid to holders of common stock) may not qualify as being pursuant to a bona fide reasonable adjustment formula. If adjustments that have the effect of increasing a U.S. Holder’s proportionate interest in our assets or earnings and profits and that do not qualify as being pursuant to a bona fide reasonable adjustment formula are made, U.S. Holders of Mandatory Convertible Preferred Stock (or Depositary Shares) may be deemed to have received a distribution even though they have not received any cash or property. Any such deemed distribution will generally be taxable to a U.S. Holder in the same manner as an actual distribution as described above under the section titled “—Distributions.” Because such distribution may not give rise to any cash from which any applicable withholding tax could be satisfied, if we (or an applicable withholding agent) are required to pay backup withholding on behalf of a U.S. Holder (as further described below under the section titled “—Information Reporting and Backup Withholding”), we (or the applicable withholding agent) could withhold such taxes from shares of common stock or current or subsequent payments of cash to, or other funds or assets of, such U.S. Holder. Generally, a U.S. Holder’s adjusted tax basis in the Mandatory Convertible Preferred Stock (or Depositary Shares) will be increased to the extent any such constructive distribution is treated as a dividend.

The IRS has proposed U.S. Treasury regulations addressing the amount and timing of constructive distributions as well as obligations of withholding agents and filing and notice obligations of the issuers in respect of such constructive distributions. If adopted as proposed, the U.S. Treasury regulations would generally provide, among other things, that (i) the amount of a constructive distribution is the excess of the fair market value of the right to acquire common stock immediately after the conversion rate adjustment over the fair market value of the right to acquire common stock (determined immediately after the conversion rate adjustment) without the adjustment, and (ii) the constructive distribution occurs at the earlier of the date the adjustment occurs under the terms of the Mandatory Convertible Preferred Stock and the date of the actual distribution of cash or property that results in the constructive distribution. The preamble to the proposed U.S. Treasury regulations notes that the regulations, if finalized, would be effective for deemed distributions occurring on or after the date of adoption, but taxpayers and withholding agents may rely on the proposed U.S. Treasury regulations prior to that date under certain circumstances.

Extraordinary Dividends

Dividends that exceed certain thresholds in relation to a U.S. Holder’s tax basis in its Depositary Shares, our Mandatory Convertible Preferred Stock, or our common stock could be characterized as an “extraordinary dividend” under the Code. If a corporate U.S. Holder receives an extraordinary dividend on stock it has held for two years or less before the dividend announcement date, such corporate U.S. Holder will generally be required to reduce its tax basis in its Depositary Shares, our Mandatory Convertible Preferred Stock, or our common stock, as applicable, with respect to which such dividend was made by the nontaxed portion of such dividend. If the amount of the reduction exceeds the corporate U.S. Holder’s tax basis in such stock, the excess is treated as taxable gain realized on the sale or other taxable disposition of the Depositary Shares, our Mandatory Convertible Preferred Stock, or our common stock and will be treated as described under the section titled “—Dispositions” below.

A non-corporate U.S. Holder will be required to treat any losses on the sale of its Depositary Shares, our Mandatory Convertible Preferred Stock, or our common stock as long-term capital losses to the extent that any extraordinary dividends received by such non-corporate U.S. Holder qualify for the preferential long-term capital gains rates discussed above under “—Distributions.”

Conversion into Common Stock

Except as provided below, a U.S. Holder generally will not recognize gain or loss upon the conversion of the Mandatory Convertible Preferred Stock (or Depositary Shares) into shares of our common stock, except that (1) a U.S. Holder’s receipt of cash (if any) in respect of dividends in arrears or possibly accrued and unpaid dividends will be taxable as described under the section titled “—Distributions” above, (2) a U.S. Holder’s receipt of common stock (if any) in respect of dividends in arrears or possibly accrued and unpaid dividends will be

S-70

taxable, while not free from doubt, as described under the section titled “—Distributions” above as if the U.S. Holder had received cash in respect of such dividends but only to the extent of the excess of the fair market value, determined as of the date of the conversion, of the common stock received in the conversion over the issue price of the Mandatory Convertible Preferred Stock (or Depositary Shares) surrendered therefor and (3) a U.S. Holder’s receipt of cash in lieu of a fractional share of our common stock will result in capital gain or loss (measured by the difference between the cash received in lieu of the fractional share of our common stock and the holder’s adjusted tax basis in the fractional share of our common stock).

Except as discussed in the next sentence, a U.S. Holder’s initial tax basis in shares of common stock received upon conversion of the Mandatory Convertible Preferred Stock (or Depositary Shares) (and any fractional shares of our common stock treated as received and then exchanged for cash) will equal the basis of the Depositary Shares representing an interest in the converted shares of Mandatory Convertible Preferred Stock and the holding period of such shares of common stock will include the holding period of the Depositary Shares representing an interest in the converted shares of Mandatory Convertible Preferred Stock. Common stock received in respect of dividends in arrears or possibly accrued but unpaid dividends and taxed as a dividend upon receipt, if any, will have a basis equal to their fair market value on the date of conversion, and a new holding period will commence therefor on the day after the conversion.

Upon certain conversions of our Mandatory Convertible Preferred Stock (or Depositary Shares), we may, in respect of any such conversion, pay a holder of our Mandatory Convertible Preferred Stock (or Depositary Shares) common stock, cash or a combination of cash and common stock in respect of the present value of future dividends (as described in the section titled “Description of Mandatory Convertible Preferred Stock—Conversion at the Option of the Holder upon Fundamental Change; Fundamental Change Dividend Make-Whole Amount”). The tax considerations of such payment of cash or common stock or combination of cash and common stock are uncertain. Although not free from doubt, we believe that the better view is to treat any such cash or shares of our common stock as additional consideration received in the conversion. If this treatment is correct, then (i) to the extent a U.S. Holder realizes gain on the conversion, such gain should be taxable to the extent of any cash received by such U.S. Holder (other than cash received in lieu of a fractional share of common stock), (ii) any such taxable gain would generally be taxable as a dividend to the extent of our current or accumulated earnings and profits attributable thereto (provided that the conversion does not result in a meaningful reduction in such U.S. Holder’s equity interest in us, in which case any such taxable gain could be treated as capital gain as further described under the section titled “—Dispositions” below), (iii) a U.S. Holder’s basis in the shares of common stock received upon conversion (including the shares of our common stock received in respect of the present value of future dividends, but excluding any fractional shares of our common stock treated as received and then exchanged for cash and the shares of our common stock in respect of dividends in arrears and possibly accrued and unpaid dividends) should equal its basis in our Mandatory Convertible Preferred Stock, or the Depositary Shares representing an interest in the Mandatory Convertible Preferred Stock being converted, increased by any gain recognized by such U.S. Holder and reduced by any cash received in respect of the present value of any future dividends and any basis allocable to any fractional shares of our common stock and (iv) a U.S. Holder’s holding period in any common stock received upon conversion (including the shares of our common stock received in respect of the present value of future dividends, but excluding the shares of our common stock in respect of dividends in arrears and possibly accrued and unpaid dividends) should include the holding period of our Mandatory Convertible Preferred Stock, or the Depositary Shares representing an interest in the Mandatory Convertible Preferred Stock being converted. For this purpose, a U.S. Holder should realize gain on the conversion equal to the excess, if any, of the sum of the cash (excluding cash received in respect of dividends in arrears and possibly accrued and unpaid dividends) and the fair market value of shares of our common stock received (including the shares of our common stock received in respect of the present value of future dividends, but excluding the shares of our common stock in respect of dividends in arrears and possibly accrued and unpaid dividends) over such U.S. Holder’s adjusted tax basis in our Mandatory Convertible Preferred Stock (or Depositary Shares) immediately prior to conversion. A U.S. Holder will not be permitted to recognize any loss realized upon the conversion of our Mandatory Convertible Preferred Stock (or Depositary Shares) into our common stock.

S-71

U.S. Holders should be aware that the tax treatment described in the preceding paragraph is not certain and may be challenged by the IRS, including on grounds that the amount received attributable to the present value of future dividends represents a taxable dividend to the extent we have current or accumulated earnings and profits at the time of conversion, as described above under the section titled “—Distributions.” U.S. Holders should consult their tax advisors to determine the specific tax treatment of such additional amounts received in their particular circumstances.

Possible Effect of a Merger, Consolidation or Other Similar Transaction

In certain situations, the issuer of the Mandatory Convertible Preferred Stock may change or the Mandatory Convertible Preferred Stock may become convertible or exchangeable into shares of another issuer or other consideration. Depending on the circumstances, such an event could result in a deemed taxable exchange of the Mandatory Convertible Preferred Stock (or Depositary Shares) for U.S. federal income tax purposes, and the modified Mandatory Convertible Preferred Stock (or Depository Shares) could be treated as newly issued at that time, potentially resulting in the recognition of taxable gain or loss. Furthermore, depending on the circumstances, following any such event, the U.S. federal income tax consequences of the conversion of the Mandatory Convertible Preferred Stock (or Depository Shares) as well as the ownership and disposition of the Mandatory Convertible Preferred Stock (or Depository Shares) and the shares of our common stock (or other consideration) received upon conversion may be different from the U.S. federal income tax consequences addressed in this discussion. U.S. Holders should consult their tax advisors regarding the U.S. federal income tax consequences of any such event.

Dispositions

Upon a sale, exchange or other taxable disposition of its Depositary Shares (other than pursuant to a withdrawal of our Mandatory Convertible Preferred Stock or common stock in respect of Depositary Shares or conversion of our Mandatory Convertible Preferred Stock into common stock), our Mandatory Convertible Preferred Stock, or our common stock, a U.S. Holder will generally recognize capital gain or loss equal to the difference, if any, between the amount realized on the sale, exchange or other taxable disposition and the U.S. Holder’s adjusted tax basis in its Depositary Shares, our Mandatory Convertible Preferred Stock, or our common stock. Such capital gain or loss will be long-term capital gain or loss if the U.S. Holder has held its Depositary Shares, our Mandatory Convertible Preferred Stock, or our common stock for more than one year at the time of disposition. A U.S. Holder’s tax basis and holding period in respect of common stock received in the conversion of the Mandatory Convertible Preferred Stock (or Depositary Shares) is discussed above under the section titled “—Conversion into Common Stock.” Long-term capital gains of non-corporate U.S. Holders (including individuals) are generally subject to U.S. federal income taxation at a maximum rate of 20%. The deductibility of capital losses is subject to significant limitations under the Code.

We may purchase the Mandatory Convertible Preferred Stock or Depositary Shares from time to time in the open market, by tender offer, exchange offer or otherwise. Assuming the disposition is “not essentially equivalent to a dividend” with respect to the U.S. Holder, the U.S. Holder generally will recognize capital gain or loss on any such disposition in an amount equal to the difference, if any, between the amount realized on such disposition and the U.S. Holder’s adjusted tax basis in its Mandatory Convertible Preferred Stock or Depositary Shares. However, depending on the U.S. Holder’s circumstances, gross proceeds from such purchase may be taxed in the same manner as a distribution as described under the section titled “—Distributions” above. If a U.S. Holder owns none or only an insubstantial amount of our voting stock (actually or constructively, based on certain attribution rules), and does not exercise any control or management over our affairs, it is likely that the gain recognized from such purchase would be considered “not essentially equivalent to a dividend” and would be treated as capital gain as described in the immediately preceding paragraph.

As discussed above, generally, a U.S. Holder of Depositary Shares should be treated for U.S. federal income tax purposes as holding the fraction of the Mandatory Convertible Preferred Stock represented by the Depositary

S-72

Shares. Accordingly, a U.S. Holder generally should not recognize income, gain, loss, or deductions upon a withdrawal of Depositary Shares for Mandatory Convertible Preferred Stock.

U.S. Holders are urged to consult their tax advisors as to the consequences of any sale, exchange, or other taxable disposition of their Depositary Shares, our Mandatory Convertible Preferred Stock, or our common stock.

Information Reporting and Backup Withholding

We or an applicable withholding agent will report to U.S. Holders and the IRS the amount of distributions (including deemed distributions) paid during each calendar year and the amount of any tax withheld unless the U.S. Holder is an exempt recipient and, when required, demonstrates this fact. Under the backup withholding rules, a U.S. Holder may be subject to backup withholding on dividends with respect to, or the proceeds of a disposition of, Depositary Shares, our Mandatory Convertible Preferred Stock, or our common stock unless the U.S. Holder is a corporation or comes within certain other exempt categories and, when required, demonstrates this fact, or provides a taxpayer identification number, certifies as to no loss of exemption from backup withholding and otherwise complies with applicable requirements of the backup withholding rules. A U.S. Holder that does not provide its correct taxpayer identification number may also be subject to penalties imposed by the IRS.

Backup withholding is not an additional tax. Any amount paid as backup withholding will be creditable against the U.S. Holder’s federal income tax liability or entitle the U.S. Holder to a refund, provided the required information is timely furnished to the IRS.

Taxation of Non-U.S. Holders

Distributions

Distributions of cash or property that we pay in respect of our Mandatory Convertible Preferred Stock (or Depositary Shares) or our common stock, including any deemed distributions resulting from certain adjustments (or failures to make adjustments) to the conversion rate (as described under the section titled “—Adjustments to Conversion Rate” below), will generally 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). Except with respect to effectively connected dividends as discussed below and subject to the discussion below under the sections titled “—Information Reporting and Backup Withholding” and “—FATCA Withholding,” dividends paid to Non-U.S. Holders will generally be subject to U.S. federal withholding tax at a 30% rate or such lower rate as may be specified by an applicable income tax treaty, provided that the withholding agent has received proper certification as to the application of that treaty. To the extent any distribution exceeds our current and accumulated earnings and profits, such excess will be treated as a tax-free return of capital to the extent of the Non-U.S. Holder’s adjusted tax basis in its Depositary Shares, our Mandatory Convertible Preferred Stock, or our common stock (determined separately for each share) which will not be subject to tax, and thereafter will be treated as capital gain (and thus treated in the manner described in the section titled “—Dispositions” below).

In order to claim the benefit of an applicable income tax treaty for dividends, a Non-U.S. Holder must satisfy applicable certification and other requirements prior to the distribution date, such as providing the withholding agent with a properly completed IRS Form W-8BEN or W-8BEN-E (or other applicable IRS Form W-8). If a Non-U.S. Holder holds our Mandatory Convertible Preferred Stock (or Depositary Shares) or our common stock through a financial institution or other intermediary, the Non-U.S. Holder will be required to provide appropriate documentation to the intermediary, which then will be required to provide appropriate documentation to the applicable withholding agent, either directly or through other intermediaries. Non-U.S. Holders eligible for a reduced rate of or an exemption from U.S. withholding tax pursuant to an income tax treaty may obtain a refund of any excess amounts withheld by timely filing an appropriate claim for refund with the IRS.

S-73

To the extent dividends paid are “effectively connected” with a Non-U.S. Holder’s conduct of a trade or business within the United States (and, if required by an applicable income tax treaty, are attributable to a permanent establishment or fixed base maintained by the Non-U.S. Holder in the United States), such effectively connected dividends will not be subject to U.S. federal withholding tax provided that certain certification and disclosure requirements are satisfied. To claim the exemption, the Non-U.S. Holder generally 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. Instead, such dividends will be subject to U.S. federal income tax on a net basis at regular U.S. federal income tax rates in the same manner as if the Non-U.S. Holder were a United States person under the Code unless an applicable income tax treaty provides otherwise. In addition, if a Non-U.S. Holder is a corporate Non-U.S. Holder, earnings and profits attributable to such dividends that are effectively connected with such holder’s conduct of a U.S. trade or business 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. We may make distributions to holders of our Mandatory Convertible Preferred Stock, including holders of Depositary Shares, that are paid in our common stock. In general, while not free from doubt, distributions paid in our common stock should be treated for U.S. federal income tax purposes as if the holder received a distribution of cash in an amount equal to the fair market value of the distributed common stock on the date of the distribution and thus should generally be subject to the rules applicable to cash distributions. Because such distribution paid in our common stock may not give rise to any cash from which any applicable withholding tax could be satisfied, we (or the applicable withholding agent) could withhold such taxes from shares of common stock or current or subsequent payments of cash to, or other funds or assets of, such Non-U.S. Holder.

Adjustments to Conversion Rate

As discussed above under the section titled, “—Taxation of U.S. Holders—Adjustments to the Conversion Rate,” certain adjustments to the conversion rate (or failure to make certain adjustments) that result in an increase in the proportionate interests of a Non-U.S. Holder in our assets or earnings and profits can result in deemed distributions to the Non-U.S. Holder, which would be treated as discussed in the section titled “—Distributions” above. Because such deemed distributions would not give rise to any cash from which any applicable withholding tax could be satisfied, we (or an applicable withholding agent) could withhold the U.S. federal withholding tax from shares of common stock or current or subsequent payments of cash to, or other funds or assets of, the Non-U.S. Holder.

Conversion into Common Stock

Except as provided in the next paragraph, a Non-U.S. Holder will not recognize gain or loss in respect of the receipt of common stock upon the conversion of the Mandatory Convertible Preferred Stock (or Depositary Shares), except that (1) any cash received that is attributable to dividends in arrears or possibly accrued and unpaid dividends, if any will be treated in the manner described above under the section titled “—Distributions,” (2) any common stock received in respect of dividends in arrears or possibly accrued and unpaid dividends, if any, while not free from doubt, should be treated in the manner described above under the sections titled “—Distributions” as if the Non-U.S. Holder had received cash in respect of such dividends, but only to the extent of the excess of the fair market value, determined as of the date of the conversion, of the common stock received in the conversion over the issue price of the Mandatory Convertible Preferred Stock (or Depositary Shares) surrendered therefor and (3) the receipt of cash in lieu of a fractional share of our common stock will generally result in gain or loss (measured by the difference between the cash received in lieu of the fractional share of our common stock and the Non-U.S. Holder’s adjusted tax basis in the fractional share of our common stock) and be treated as described below under the section titled “—Dispositions.”

Upon certain conversions of our Mandatory Convertible Preferred Stock (or Depositary Shares), we may, in respect of any such conversion, pay a holder of Depositary Shares (or Mandatory Convertible Preferred Stock) common stock, cash or a combination of cash and common stock in respect of the present value of future

S-74

dividends (as described in the section titled “Description of Mandatory Convertible Preferred Stock—Conversion at the Option of the Holder upon Fundamental Change; Fundamental Change Dividend Make-Whole Amount”). As described above under the section titled “—Taxation of U.S. Holders—Conversion into Common Stock,” the tax considerations of such payment of cash or common stock or combination of cash and common stock are uncertain. Although not free from doubt, we believe that the better view is to treat any such cash or shares of our common stock as additional consideration received in the conversion.

Nevertheless, an applicable withholding agent may disagree and may treat any such payment as a dividend that is subject to U.S. federal withholding tax at a 30% rate as described above under the section titled “—Distributions” unless (1) the Non-U.S. Holder qualifies for an exception or a reduction of this rate under an applicable income tax treaty or (2) such dividend is effectively connected income and, in each case, an appropriate certification is provided. If any such cash, shares of our common stock or combination of cash and common stock is treated as additional consideration, gain, if any, may be recognized to the extent of any cash received other than cash received in lieu of a fractional share of common stock (but would only be taxable as discussed below under the section titled “—Dispositions”). In the event the applicable withholding agent is unable to determine the extent to which any payment of cash or common stock is subject to dividend withholding, it may withhold 30% (or such lower rate as may be specified by an applicable income tax treaty) from such payment.

Dispositions

Subject to the discussions above under the section titled “—Distributions,” and below under the sections titled “—Information Reporting and Backup Withholding” and “—FATCA Withholding,” a Non-U.S. Holder will generally not be subject to U.S. federal income tax with respect to gain realized on the sale or other taxable disposition of its Depositary Shares, our Mandatory Convertible Preferred Stock, or our common stock, unless:

•

the Non-U.S. Holder is an individual who is present in the United States for 183 days or more in the taxable year of the sale or other taxable disposition, and certain other conditions are met;

•

the gain is “effectively connected” with such Non-U.S. Holder’s conduct of a trade or business within the United States, and, if required under an applicable treaty, the gain is attributable to a permanent establishment or fixed base that such Non-U.S. Holder maintains in the United States; or

•

our Mandatory Convertible Preferred Stock (including Depositary Shares) or our common stock constitutes a “United States real property interest” by reason of our status as a “United States real property holding corporation” for U.S. federal income tax purposes at any time within the shorter of the five-year period ending on the date of such sale, exchange, or other taxable disposition or such Non-U.S. Holder’s holding period.

We believe that we have not been and are not, and we do not anticipate becoming, a “United States real property holding corporation” for U.S. federal income tax purposes, although no assurances can be given in this regard.

To the extent any gain is recognized by a Non-U.S. Holder described in the first bullet above, such gain (net of certain U.S.-source capital losses, provided the Non-U.S. Holder has timely filed U.S. federal income tax returns with respect to such losses) will be subject to U.S. federal income tax at a rate of 30% (or lower applicable income tax treaty rate).

To the extent that gain recognized is effectively connected with the Non-U.S. Holder’s conduct of a U.S. trade or business and, if required by an income tax treaty, the gain is attributable to a permanent establishment or fixed base maintained by the Non-U.S. Holder in the United States, as described in the second bullet above, such gain will be subject to U.S. federal income tax on a net basis at regular rates in the same manner as if such Non-U.S. Holder were a United States person as described under the Code. In addition, if a Non-U.S. Holder is a corporate Non-U.S. Holder, earnings and profits attributable to such gain that are effectively connected with such holder’s conduct of a U.S. trade or business may also be subject to a branch profits tax at a rate of 30% or such lower rate as may be specified in an applicable income tax treaty.

S-75

We may purchase the Mandatory Convertible Preferred Stock or Depositary Shares from time to time in the open market, by tender offer, exchange offer or otherwise. Assuming the disposition is “not essentially equivalent to a dividend” with respect to the Non-U.S. Holder, the Non-U.S. Holder generally will recognize gain or loss on any such disposition in an amount equal to the difference, if any, between the amount realized on such disposition and the Non-U.S. Holder’s adjusted tax basis in its Mandatory Convertible Preferred Stock or Depositary Shares. Any such gain generally will be taxed to the extent described in the preceding paragraphs. However, depending on the Non-U.S. Holder’s circumstances, gross proceeds from such purchase may be taxed in the same manner as a distribution as described under the section titled “—Distributions” above. If a Non-U.S. Holder owns none or only an insubstantial amount of our voting stock (actually or constructively, based on certain attribution rules), and does not exercise any control or management over our affairs, it is likely that the gain recognized from such purchase would be considered “not essentially equivalent to a dividend” and would be treated as described in the preceding paragraphs.

As discussed above, generally, a Non-U.S. Holder of Depositary Shares should be treated for U.S. federal income tax purposes as holding the fraction of the Mandatory Convertible Preferred Stock represented by the Depositary Shares. Accordingly, a Non-U.S. Holder generally should not recognize income, gain, loss, or deductions upon a withdrawal of Depositary Shares for Mandatory Convertible Preferred Stock.

Non-U.S. Holders are urged to consult their own tax advisors as to the consequences of any sale, exchange, or other taxable disposition of their Depositary Shares, our Mandatory Convertible Preferred Stock, or our common stock.

Information Reporting and Backup Withholding

Non-U.S. Holders generally will be required to comply with certain certification procedures to establish that they are not United States persons (as defined in the Code) in order to avoid backup withholding with respect to dividends (including deemed dividends) paid to such Non-U.S. Holders or the proceeds received by such Non-U.S. Holders on the sale, exchange, or other taxable disposition of Depositary Shares, our Mandatory Convertible Preferred Stock, or our common stock. In addition, we are required to report annually to the IRS and to each Non-U.S. Holder the amount of any distributions (including deemed distributions) paid to such Non-U.S. Holder, regardless of whether any tax was actually withheld. Copies of the information returns reporting such distributions and the amount withheld may also be made available to the tax authorities in the country in which the Non-U.S. Holder resides or is established under the provisions of an applicable income tax treaty. Payments of proceeds from the sale or other disposition by a Non-U.S. Holder of Depositary Shares, our Mandatory Convertible Preferred Stock, or our common stock to or through a foreign office of a U.S. broker or of a foreign broker with certain specified U.S. connections will be subject to information reporting requirements, but generally not backup withholding unless the payor has actual knowledge or reason to know that the payee is a United States person. Payments of proceeds from a sale or other disposition of Depositary Shares, our Mandatory Convertible Preferred Stock, or our common stock to or through the U.S. office of a broker will be subject to information reporting and backup withholding unless the payee certifies under penalties of perjury that it is not a United States person or otherwise establishes an exemption.

Backup withholding is not an additional tax. Any amounts withheld under the backup withholding rules generally will be allowed as a refund or a credit against a Non-U.S. Holder’s U.S. federal income tax liability, provided that certain required information is timely furnished to the IRS.

FATCA Withholding

Sections 1471 through 1474 of the Code, and the U.S. Treasury regulations and other administrative guidance issued thereunder, commonly referred to as “FATCA,” generally impose a U.S. federal withholding tax of 30% on dividends (including deemed dividends), and, subject to the proposed U.S. Treasury regulations discussed below, the gross proceeds from a sale or other disposition of, Depositary Shares, our Mandatory Convertible Preferred Stock, or our common stock paid to (i) a “foreign financial institution” (as specifically

S-76

defined for this purpose), unless such institution enters into an agreement with the U.S. government to, among other things, withhold on certain payments and to collect and provide to the U.S. tax authorities certain information regarding certain U.S. account holders of such institution (which includes certain equity and debt holders of such institution, as well as certain account holders that are foreign entities with U.S. owners) or otherwise qualifies for an exemption from these rules, or (ii) a “non-financial foreign entity” (as defined in the Code), unless such entity provides the withholding agent with either a certification that it does not have any direct or indirect “substantial United States owners” (as defined in the Code) or provides the applicable withholding agent with a certification identifying, and information regarding, such substantial United States owners, or otherwise qualifies for an exemption from these rules. An intergovernmental agreement between the U.S. and the applicable non-U.S. jurisdiction may modify the requirements described in this paragraph.

U.S. Treasury regulations proposed in December 2018 eliminate FATCA withholding on the gross proceeds from a sale or other disposition of Depositary Shares, our Mandatory Convertible Preferred Stock, or our common stock and may be relied upon by taxpayers until final regulations are issued.

We will not pay additional amounts or “gross up” payments to holders as a result of any withholding or deduction for taxes imposed under FATCA. Under certain circumstances, certain Non-U.S. Holders might be eligible for refunds or credits of such taxes. Investors are encouraged to consult with their tax advisors regarding the implications of FATCA to their particular circumstances.

The underwriters will have 30 days from the date of this prospectus supplement to exercise this over-allotment option. If any Depositary Shares are purchased pursuant to this over-allotment option, the underwriters will severally purchase Depositary Shares in approximately the same proportion as set forth in the table above.

It is expected that delivery of the Depositary Shares will be made against payment therefor on , 2026 (the “expected settlement date”), which is the second business day following the trade date for the Depositary Shares (such settlement cycle being referred to as “T+2”). Under Rule 15c6-1 under the Exchange Act, trades in the secondary market generally are required to settle in one business day, unless the parties to any such trade expressly agree otherwise. Accordingly, purchasers who wish to trade the Depositary Shares prior to the business day preceding the expected settlement date will be required, by virtue of the fact that the Depositary Shares initially will settle T+2, to specify an alternative settlement cycle at the time of any such trade to prevent a failed settlement. Purchasers of the Depositary Shares who wish to trade the Depositary Shares prior to the business day preceding the expected settlement date should consult their own advisors.

The following table shows the per share and total underwriting discounts to be paid to the underwriters by us. Such amounts are shown assuming both no exercise and full exercise of the underwriters’ over-allotment option.

Depositary Shares sold by the underwriters to the public will initially be offered at the public offering price set forth on the cover of this prospectus.

After the initial offering of the Depositary Shares, the representatives may change the offering price and the other selling terms. The offering of the Depositary 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.

Listing

We intend to apply to list the Depositary Shares on the Nasdaq Global Select Market under the symbol “SMCIP.” No assurance can be given that the Depositary Shares will be listed or that any such application for listing will be

S-80

approved. Neither we nor the underwriters can assure investors that an active trading market will develop for the Depositary Shares, or that the Depositary Shares will trade in the public market at or above the initial public offering price. Our common stock is listed on the Nasdaq Global Select Market under the symbol “SMCI.”

We estimate that our offering expenses, excluding underwriting discounts, will be approximately $ million. ICR Capital LLC is acting as financial advisor to us in connection with this offering and will receive a fee upon the completion of this offering. ICR Capital LLC is not acting as an underwriter under the underwriting agreement and will not offer or sell any securities in this offering.

In connection with this offering, the underwriters may purchase and sell Depositary Shares in the open market. These transactions may include short sales, stabilizing transactions and purchases to cover positions created by short sales. Short sales involve the sale by the underwriters of a greater number of Depositary Shares than they are required to purchase in the offering, and a short position represents the amount of such sales that have not been covered by subsequent purchases. A “covered short position” is a short position that is not greater than the amount of additional Depositary Shares for which the underwriters’ option described above may be exercised. The underwriters may cover any covered short position by either exercising their option to purchase additional Depositary Shares or purchasing Depositary Shares in the open market. In determining the source of Depositary Shares to cover the covered short position, the underwriters will consider, among other things, the price of Depositary Shares available for purchase in the open market as compared to the price at which they may purchase additional Depositary Shares pursuant to the option described above. “Naked” short sales are any short sales that create a short position greater than the amount of additional Depositary Shares for which the option described above may be exercised. The underwriters must cover any such naked short position by purchasing Depositary Shares in the open market. 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 Depositary Shares in the open market after pricing that could adversely affect investors who purchase in the offering. Stabilizing transactions consist of various bids for or purchases of Depositary Shares made by the underwriters in the open market prior to the completion of the offering.

The underwriters may also impose a penalty bid. This occurs when a particular underwriter repays to the underwriters a portion of the underwriting discount received by it because the representatives have repurchased Depositary Shares sold by or for the account of such underwriter in stabilizing or short covering transactions.

Purchases to cover a short position and stabilizing transactions, as well as other purchases by the underwriters for their own accounts, may have the effect of preventing or retarding a decline in the market price of the Depositary Shares, and together with the imposition of the penalty bid, may stabilize, maintain or otherwise affect the market price of the Depositary Shares. As a result, the price of the Depositary Shares may be higher than the price that otherwise might exist in the open market. The underwriters are not required to engage in these activities and may end any of these activities at any time. These transactions may be effected on the Nasdaq Global Select Market, in the over-the-counter market or otherwise.

The underwriters and their respective affiliates are full service financial institutions engaged in various activities, which may include sales and trading, commercial and investment banking, advisory, investment management, investment research, principal investment, hedging, market making, brokerage and other financial and non-financial activities and services. Certain of the underwriters and their respective affiliates have provided, and may in the future provide, a variety of these services to us and to persons and entities with relationships with us, for which they received or will receive customary fees and expenses. In particular, the representatives and/or their affiliates act as lenders, administrative agents, bookrunners and/or arrangers under our credit agreements, including the Credit Agreement. The underwriters are also underwriters in the Common Stock Offering and sales agents in the ATM Program.

In the ordinary course of their various business activities, the underwriters and their respective affiliates, officers, directors and employees may purchase, sell or hold a broad array of investments and actively trade securities,

S-81

derivatives, loans, commodities, currencies, credit default swaps and other financial instruments for their own account and for the accounts of 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. The underwriters and their respective affiliates may also communicate independent investment recommendations, market color or trading ideas and/or publish or express independent research views in respect of such assets, securities or instruments and may at any time hold, or recommend to clients that they should acquire, long and/or short positions in such assets, securities and instruments.

Concurrent Financing Transactions

Concurrently with this offering, we are offering $1.25 billion of our common stock, pursuant to a separate prospectus supplement. We expect to grant the underwriters of the Common Stock Offering a 30-day option to purchase up to an additional $187.5 million of our common stock, solely to cover sales in excess of the firm shares. In addition, concurrently with this offering and pursuant to a separate prospectus supplement, we intend to enter into an Equity Distribution Agreement with certain agents under which we may sell up to $2 billion of shares of our common stock in the ATM Program. The closing of this offering is not conditioned upon the closing of the Common Stock Offering or entry into the ATM Program. Neither the closing of the Common Stock Offering nor entry into the ATM Program is conditioned upon the closing of this offering. We cannot assure you that the Common Stock Offering or the establishment of the ATM Program will be completed on the terms described herein, or at all. Nothing contained herein shall constitute an offer to sell or a solicitation of an offer to buy any of the common stock being offered in the Common Stock Offering or the common stock being offered from time to time in the ATM Program. See the section titled “Description of the Concurrent Financing Transactions.”

This prospectus only provides you with a general description of the securities we may offer. Each time we sell securities, we will provide a prospectus supplement that will contain specific information about the terms of that offering.

We believe our expectations regarding future events are based on reasonable assumptions; however, these assumptions may not be accurate and are subject to various risks, uncertainties and assumptions that could cause actual results to differ materially from those anticipated or implied in our forward-looking statements due to a number of factors including, but not limited to, those set forth under the section entitled “Risk Factors” in our most recent Annual Report on Form 10-K and subsequent Quarterly Reports on Form 10-Q, which are incorporated and deemed to be incorporated by reference in this prospectus and may be obtained as described under “Where You Can Find More Information,” and, if applicable, in the applicable prospectus supplement and any related free writing prospectus, as well as the risks and uncertainties discussed in our consolidated financial statements, related notes and the other information included in this prospectus, the applicable prospectus supplement, any related free writing prospectus and the documents incorporated and deemed to be incorporated by reference herein.

USE OF PROCEEDS

We intend to use the net proceeds from the sale of securities issued pursuant to this registration statement for general corporate purposes, which may include capital expenditures, repayment of indebtedness, future investments or acquisitions and payment of cash dividends on or repurchases of our common stock. If we decide to use the net proceeds from a particular offering of securities for a specific purpose, we will describe that purpose in the related prospectus supplement.

DESCRIPTION OF CAPITAL STOCK

The following brief description of the capital stock of Super Micro Computer, Inc. is a summary. This summary is not complete and is subject to and qualified in its entirety by reference to the complete text of our Amended and Restated Certificate of Incorporation, as amended by the Certificate of Amendment to the Amended and Restated Certificate of Incorporation (together, our “Certificate of Incorporation”) and our Amended and Restated Bylaws (our “Bylaws”) previously filed with the SEC and incorporated by reference herein. We encourage you to read our Certificate of Incorporation and our Bylaws carefully, and the applicable provisions of the Delaware General Corporate Law (the “DGCL”) for more information.

General

The Company’s Certificate of Incorporation provides that it may issue up to 1,000,000,000 shares of common stock, $0.001 par value per share, and 10,000,000 shares of preferred stock, $0.001 par value per share.

Common Stock

The holders of our common stock are entitled to one vote for each share held of record on all matters submitted to a vote of stockholders. At a meeting of stockholders at which a quorum is present, any election of directors will be determined by a plurality of the votes cast by stockholders entitled to vote and any other matter will be determined by a majority of the voting power of the shares present and entitled to vote on the matter, except when a different vote is required by express provision of law, our Certificate of Incorporation or our Bylaws. Subject to preferences applicable to any outstanding preferred stock, holders of common stock are entitled to receive ratably any dividend declared by our board of directors (the “Board”). In the event of a liquidation, dissolution or winding up of the Company, holders of our common stock are entitled to share ratably in the assets remaining after payment of liabilities and the liquidation preferences of any outstanding preferred stock. Holders of our common stock have no preemptive, conversion or redemption rights. Each outstanding share of common stock is fully paid and non-assessable.

Preferred Stock

There are 10,000,000 shares of undesignated preferred stock authorized for issuance. The Board has the authority, without further action by the stockholders, to issue preferred stock in one or more series. In addition, the Board may fix the rights, preferences and privileges of any preferred stock it determines to issue. Any or all of these rights may be superior to the rights of the common stock. Preferred stock could thus be issued quickly with terms calculated to delay or prevent a change in control of our company or to make removal of management more difficult. Additionally, the issuance of preferred stock may decrease the market price of our common stock.

Anti-Takeover Provisions

Delaware Law

We are subject to Section 203 of the DGCL regulating corporate takeovers, which prohibits a Delaware corporation from engaging in any business combination with an “interested stockholder” during the three year period after such stockholder becomes an “interested stockholder,” unless:

•

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

•

the interested stockholder owned at least 85% of the voting stock of the corporation outstanding at the time the transaction commenced, excluding for purposes of determining the number of shares outstanding (a) shares owned by persons who are directors and also officers, and (b) shares owned by

employee stock plans in which employee participants do not have the right to determine confidentially whether shares held subject to the plan will be tendered in a tender or exchange offer; or

•

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

Except as otherwise specified in Section 203, an “interested stockholder” is defined to include:

•

any person that is the owner of 15% or more of the outstanding voting securities of the corporation, or is an affiliate or associate of the corporation and was the owner of 15% or more of the outstanding voting stock of the corporation at any time within three years immediately prior to the date of determination; and

•

the affiliates and associates of any such person.

Certificate of Incorporation and Bylaws

Our Certificate of Incorporation and Bylaws provide that:

•

no action can be taken by stockholders except at an annual or special meeting of the stockholders called in accordance with our Bylaws, and stockholders may not act by written consent;

•

the approval of holders of two-thirds of the shares entitled to vote at an election of directors is required to adopt, or to alter, amend or repeal our Bylaws or amend or repeal the provisions of our Certificate of Incorporation regarding the election and removal of directors, the ability of stockholders to take action and the indemnification of our directors, and the percentage of shares necessary to amend the Certificate of Incorporation;

•

the Board is expressly authorized to adopt, amend or repeal our Bylaws;

•

holders of at least 10% or more of our common stock may call special meetings of the stockholders;

•

the Board is divided into three classes of service with staggered three-year terms. This means that only one class of directors is elected at each annual meeting of stockholders, with the other classes continuing for the remainder of their respective terms;

•

the Board is authorized to issue preferred stock without stockholder approval; and

•

we will indemnify officers and directors against losses that may incur in connection with investigations and legal proceedings resulting from their services to us, which may include services in connection with takeover defense measures.

These provisions may make it more difficult for stockholders to take specific corporate actions and could have the effect of delaying or preventing a change in control of our company.

Limitation of Liability

As permitted by the DGCL, our Certificate of Incorporation provides that our directors will not be personally liable to us or our stockholders for monetary damages for breach of fiduciary duty as a director, except for liability:

•

for any breach of the director’s duty of loyalty to us or our stockholders;

•

for acts or omissions not in good faith or that involve intentional misconduct or a knowing violation of law;

•

under Section 174 of the DGCL, relating to unlawful payment of dividends or unlawful stock purchase or redemption of stock; or

•

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

As a result of this provision, we and our stockholders may be unable to obtain monetary damages from a director for breach of his or her duty of care. Our Certificate of Incorporation and Bylaws also provide for the indemnification of our directors and officers to the fullest extent authorized by the DGCL. The indemnification provided under our Certificate of Incorporation and Bylaws includes the right to be paid expenses in advance of any proceeding for which indemnification may be payable, provided that the payment of these expenses incurred by a director or officer in advance of the final disposition of a proceeding may be made only upon delivery to us of an undertaking, by or on behalf of the director or officer to repay all amounts so paid in advance if it is ultimately determined that the director or officer is not entitled to be indemnified.

Under our Bylaws, we have the power to purchase and maintain insurance to the extent reasonably available on behalf of any person who is or was one of our directors, officers, employees or agents, or is or was serving at our request as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise against any liability asserted against the person or incurred by the person in any of these capacities, or arising out of the persons fulfilling one of these capacities, and related expenses, whether or not we would have the power to indemnify the person against the claim under the provisions of the DGCL. We intend to maintain director and officer liability insurance on behalf of our directors and officers.

Transfer and Exchange

Each debt security will be represented by either one or more global securities registered in the name of The Depository Trust Company (the “Depositary”) or a nominee of the Depositary (we will refer to any debt security represented by a global debt security as a “book-entry debt security”), or a certificate issued in definitive registered form (we will refer to any debt security represented by a certificated security as a “certificated debt security”) as set forth in the applicable prospectus supplement. Except as set forth under the heading “Global Debt Securities and Book-Entry System” below, book-entry debt securities will not be issuable in certificated form.

Certificated Debt Securities. You may transfer or exchange certificated debt securities at any office we maintain for this purpose in accordance with the terms of the indenture. (Section 2.4) No service charge will be made for any transfer or exchange of certificated debt securities, but we may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection with a transfer or exchange. (Section 2.7)

You may effect the transfer of certificated debt securities and the right to receive the principal of, premium and interest on certificated debt securities only by surrendering the certificate representing those certificated debt securities and either reissuance by us or the trustee of the certificate to the new holder or the issuance by us or the trustee of a new certificate to the new holder.

Global Debt Securities and Book-Entry System. Each global debt security representing book-entry debt securities will be deposited with, or on behalf of, the Depositary, and registered in the name of the Depositary or a nominee of the Depositary. Please see “Global Securities.”

Covenants

We will set forth in the applicable prospectus supplement any restrictive covenants applicable to any issue of debt securities. (Article IV)

No Protection in the Event of a Change of Control

Unless we state otherwise in the applicable prospectus supplement, the debt securities will not contain any provisions which may afford holders of the debt securities protection in the event we have a change in control or in the event of a highly leveraged transaction (whether or not such transaction results in a change in control), which could adversely affect holders of debt securities.

Consolidation, Merger and Sale of Assets

We may not consolidate with or merge with or into, or convey, transfer or lease all or substantially all of our properties and assets to any person (a “successor person”) unless:

•

we are the surviving entity or the successor person (if other than Super Micro) is a corporation, partnership, trust or other entity organized and validly existing under the laws of any U.S. domestic jurisdiction and expressly assumes our obligations on the debt securities and under the indenture; and

•

immediately after giving effect to the transaction, no Default or Event of Default, shall have occurred and be continuing.

Notwithstanding the above, any of our subsidiaries may consolidate with, merge into or transfer all or part of its properties to us. (Section 5.1)

Events of Default

“Event of Default” means with respect to any series of debt securities, any of the following:

•

default in the payment of any interest upon any debt security of that series when it becomes due and payable, and continuance of such default for a period of 30 days (unless the entire amount of the payment is deposited by us with the trustee or with a paying agent prior to the expiration of the 30-day period);

•

default in the payment of principal of any security of that series at its maturity;

•

default in the performance or breach of any other covenant or warranty by us in the indenture (other than a covenant or warranty that has been included in the indenture solely for the benefit of a series of debt securities other than that series), which default continues uncured for a period of 60 days after we receive written notice from the trustee or Opendoor and the trustee receive written notice from the holders of not less than 25% in principal amount of the outstanding debt securities of that series as provided in the indenture;

•

certain voluntary or involuntary events of bankruptcy, insolvency or reorganization of Super Micro;

•

any other Event of Default provided with respect to debt securities of that series that is described in the applicable prospectus supplement. (Section 6.1)

No Event of Default with respect to a particular series of debt securities (except as to certain events of bankruptcy, insolvency or reorganization) necessarily constitutes an Event of Default with respect to any other series of debt securities. (Section 6.1) The occurrence of certain Events of Default or an acceleration under the indenture may constitute an event of default under certain indebtedness of ours or our subsidiaries outstanding from time to time.

We will provide the trustee written notice of any Default or Event of Default within 30 days of becoming aware of the occurrence of such Default or Event of Default, which notice will describe in reasonable detail the status of such Default or Event of Default and what action we are taking or propose to take in respect thereof. (Section 6.1)

If an Event of Default with respect to debt securities of any series at the time outstanding occurs and is continuing, then the trustee or the holders of not less than 25% in principal amount of the outstanding debt securities of that series may, by a notice in writing to us (and to the trustee if given by the holders), declare to be due and payable immediately the principal of (or, if the debt securities of that series are discount securities, that portion of the principal amount as may be specified in the terms of that series) and accrued and unpaid interest, if any, on all debt securities of that series. In the case of an Event of Default resulting from certain events of bankruptcy, insolvency or reorganization, the principal (or such specified amount) of and accrued and unpaid interest, if any, on all outstanding debt securities will become and be immediately due and payable without any declaration or other act on the part of the trustee or any holder of outstanding debt securities. At any time after a declaration of acceleration with respect to debt securities of any series has been made, but before a judgment or decree for payment of the money due has been obtained by the trustee, the holders of a majority in principal amount of the outstanding debt securities of that series may rescind and annul the acceleration if all Events of Default, other than the non-payment of accelerated principal and interest, if any, with respect to debt securities of that series, have been cured or waived as provided in the indenture. (Section 6.2) We refer you to the prospectus

supplement relating to any series of debt securities that are discount securities for the particular provisions relating to acceleration of a portion of the principal amount of such discount securities upon the occurrence of an Event of Default.

The indenture provides that the trustee may refuse to perform any duty or exercise any of its rights or powers under the indenture unless the trustee receives indemnity satisfactory to it against any cost, liability or expense which might be incurred by it in performing such duty or exercising such right or power. (Section 7.1(e)) Subject to certain rights of the trustee, the holders of a majority in principal amount of the outstanding debt securities of any series will have the right to direct the time, method and place of conducting any proceeding for any remedy available to the trustee or exercising any trust or power conferred on the trustee with respect to the debt securities of that series. (Section 6.12)

No holder of any debt security of any series will have any right to institute any proceeding, judicial or otherwise, with respect to the indenture or for the appointment of a receiver or trustee, or for any remedy under the indenture, unless:

•

that holder has previously given to the trustee written notice of a continuing Event of Default with respect to debt securities of that series; and

•

the holders of not less than 25% in principal amount of the outstanding debt securities of that series have made written request, and offered indemnity or security satisfactory to the trustee, to the trustee to institute the proceeding as trustee, and the trustee has not received from the holders of not less than a majority in principal amount of the outstanding debt securities of that series a direction inconsistent with that request and has failed to institute the proceeding within 60 days. (Section 6.7)

Notwithstanding any other provision in the indenture, the holder of any debt security will have an absolute and unconditional right to receive payment of the principal of, premium and any interest on that debt security on or after the due dates expressed in that debt security and to institute suit for the enforcement of payment. (Section 6.8)

The indenture requires us, within 120 days after the end of our fiscal year, to furnish to the trustee a statement as to compliance with the indenture. (Section 4.3) If a Default or Event of Default occurs and is continuing with respect to the securities of any series and if it is known to a responsible officer of the trustee, the trustee shall mail to each Securityholder of the securities of that series notice of a Default or Event of Default within 90 days after it occurs or, if later, after a responsible officer of the trustee has knowledge of such Default or Event of Default. The indenture provides that the trustee may withhold notice to the holders of debt securities of any series of any Default or Event of Default (except in payment on any debt securities of that series) with respect to debt securities of that series if the trustee determines in good faith that withholding notice is in the interest of the holders of those debt securities. (Section 7.5).

Modification and Waiver

We and the trustee may modify, amend or supplement the indenture or the debt securities of any series without the consent of any holder of any debt security:

•

to cure any ambiguity, defect or inconsistency;

•

to comply with covenants in the indenture described above under the heading “Consolidation, Merger and Sale of Assets”;

•

to provide for uncertificated securities in addition to or in place of certificated securities;

•

to add guarantees with respect to debt securities of any series or secure debt securities of any series;

•

to surrender any of our rights or powers under the indenture;

•

to add covenants or events of default for the benefit of the holders of debt securities of any series;

•

to comply with the applicable procedures of the applicable depositary;

to make any change that does not adversely affect the rights of any holder of debt securities;

to provide for the issuance of and establish the form and terms and conditions of debt securities of any series as permitted by the indenture;

•

to effect the appointment of a successor trustee with respect to the debt securities of any series and to add to or change any of the provisions of the indenture to provide for or facilitate administration by more than one trustee; orto comply with requirements of the SEC in order to effect or maintain the qualification of the indenture under the Trust Indenture Act of 1939, as amended. (Section 9.1)

We may also modify and amend the indenture with the consent of the holders of at least a majority in principal amount of the outstanding debt securities of each series affected by the modifications or amendments. We may not make any modification or amendment without the consent of the holders of each affected debt security then outstanding if that amendment will:

•

reduce the amount of debt securities whose holders must consent to an amendment, supplement or waiver;

•

reduce the rate of or extend the time for payment of interest (including default interest) on any debt security;

•

reduce the principal of or premium on or change the fixed maturity of any debt security or reduce the amount of, or postpone the date fixed for, the payment of any sinking fund or analogous obligation with respect to any series of debt securities;

•

reduce the principal amount of discount securities payable upon acceleration of maturity;

•

waive a default in the payment of the principal of, premium or interest on any debt security (except a rescission of acceleration of the debt securities of any series by the holders of at least a majority in aggregate principal amount of the then outstanding debt securities of that series and a waiver of the payment default that resulted from such acceleration);

•

make the principal of or premium or interest on any debt security payable in currency other than that stated in the debt security;

•

make any change to certain provisions of the indenture relating to, among other things, the right of holders of debt securities to receive payment of the principal of, premium and interest on those debt securities and to institute suit for the enforcement of any such payment and to waivers or amendments; or

•

waive a redemption payment with respect to any debt security. (Section 9.3)

Except for certain specified provisions, the holders of at least a majority in principal amount of the outstanding debt securities of any series may on behalf of the holders of all debt securities of that series waive our compliance with provisions of the indenture. (Section 9.2) The holders of a majority in principal amount of the outstanding debt securities of any series may on behalf of the holders of all the debt securities of such series waive any past default under the indenture with respect to that series and its consequences, except a default in the payment of the principal of, premium or any interest on any debt security of that series; provided, however, that the holders of a majority in principal amount of the outstanding debt securities of any series may rescind an acceleration and its consequences, including any related payment default that resulted from the acceleration. (Section 6.13)

Defeasance of Debt Securities and Certain Covenants in Certain Circumstances

Legal Defeasance. The indenture provides that, unless otherwise provided by the terms of the applicable series of debt securities, we may be discharged from any and all obligations in respect of the debt securities of

any series (subject to certain exceptions). We will be so discharged upon the irrevocable deposit with the trustee, in trust, of money and/or U.S. government obligations or, in the case of debt securities denominated in a single currency other than U.S. Dollars, government obligations of the government that issued or caused to be issued such currency, that, through the payment of interest and principal in accordance with their terms, will provide money or U.S. government obligations in an amount sufficient in the opinion of a nationally recognized firm of independent public accountants or investment bank to pay and discharge each installment of principal, premium and interest on and any mandatory sinking fund payments in respect of the debt securities of that series on the stated maturity of those payments in accordance with the terms of the indenture and those debt securities.

This discharge may occur only if, among other things, we have delivered to the trustee an opinion of counsel stating that we have received from, or there has been published by, the United States Internal Revenue Service a ruling or, since the date of execution of the indenture, there has been a change in the applicable United States federal income tax law, in either case to the effect that, and based thereon such opinion shall confirm that, the beneficial owners of the debt securities of that series will not recognize income, gain or loss for United States federal income tax purposes as a result of the deposit, defeasance and discharge and will be subject to United States federal income tax on the same amounts and in the same manner and at the same times as would have been the case if the deposit, defeasance and discharge had not occurred. (Section 8.3)

Defeasance of Certain Covenants. The indenture provides that, unless otherwise provided by the terms of the applicable series of debt securities, upon compliance with certain conditions:

•

we may omit to comply with the covenant described under the heading “Consolidation, Merger and Sale of Assets” and certain other covenants set forth in the indenture, as well as any additional covenants which may be set forth in the applicable prospectus supplement; and

•

any omission to comply with those covenants will not constitute a Default or an Event of Default with respect to the debt securities of that series (“covenant defeasance”).

The conditions include:

•

depositing with the trustee money and/or U.S. government obligations or, in the case of debt securities denominated in a single currency other than U.S. Dollars, government obligations of the government that issued or caused to be issued such currency, that, through the payment of interest and principal in accordance with their terms, will provide money in an amount sufficient in the opinion of a nationally recognized firm of independent public accountants or investment bank to pay and discharge each installment of principal of, premium and interest on and any mandatory sinking fund payments in respect of the debt securities of that series on the stated maturity of those payments in accordance with the terms of the indenture and those debt securities; and

•

delivering to the trustee an opinion of counsel to the effect that the holders of the debt securities of that series will not recognize income, gain or loss for United States federal income tax purposes as a result of the deposit and related covenant defeasance and will be subject to United States federal income tax on the same amounts and in the same manner and at the same times as would have been the case if the deposit and related covenant defeasance had not occurred. (Section 8.4)

No Personal Liability of Directors, Officers, Employees or Securityholders

None of our past, present or future directors, officers, employees or securityholders, as such, will have any liability for any of our obligations under the debt securities or the indenture or for any claim based on, or in respect or by reason of, such obligations or their creation. By accepting a debt security, each holder waives and releases all such liability. This waiver and release is part of the consideration for the issue of the debt securities. However, this waiver and release may not be effective to waive liabilities under U.S. federal securities laws, and it is the view of the SEC that such a waiver is against public policy.

Governing Law

The indenture and the debt securities, including any claim or controversy arising out of or relating to the indenture or the securities, will be governed by the laws of the State of New York.

The indenture will provide that we, the trustee and the holders of the debt securities (by their acceptance of the debt securities) irrevocably waive, to the fullest extent permitted by applicable law, any and all right to trial by jury in any legal proceeding arising out of or relating to the indenture, the debt securities or the transactions contemplated thereby.

The indenture will provide that any legal suit, action or proceeding arising out of or based upon the indenture or the transactions contemplated thereby may be instituted in the federal courts of the United States of America located in the City of New York or the courts of the State of New York in each case located in the City of New York, and we, the trustee and the holder of the debt securities (by their acceptance of the debt securities) irrevocably submit to the non-exclusive jurisdiction of such courts in any such suit, action or proceeding. The indenture will further provide that service of any process, summons, notice or document by mail (to the extent allowed under any applicable statute or rule of court) to such party’s address set forth in the indenture will be effective service of process for any suit, action or other proceeding brought in any such court. The indenture will further provide that we, the trustee and the holders of the debt securities (by their acceptance of the debt securities) irrevocably and unconditionally waive any objection to the laying of venue of any suit, action or other proceeding in the courts specified above and irrevocably and unconditionally waive and agree not to plead or claim any such suit, action or other proceeding has been brought in an inconvenient forum. (Section 10.10).

DESCRIPTION OF WARRANTS

We may issue warrants to purchase our debt or equity securities or securities of third parties or other rights, including rights to receive payment in cash or securities based on the value, rate or price of one or more specified commodities, currencies, securities or indices, or any combination of the foregoing. Warrants may be issued independently or together with any other securities and may be attached to, or separate from, such securities. Each series of warrants will be issued under a separate warrant agreement to be entered into between us and a warrant agent. The terms of any warrants to be issued and a description of the material provisions of the applicable warrant agreement will be set forth in the applicable prospectus supplement.

DESCRIPTION OF PURCHASE CONTRACTS

We may issue purchase contracts for the purchase or sale of:

•

debt or equity securities issued by us or securities of third parties, a basket of such securities, an index or indices of such securities or any combination of the above as specified in the applicable prospectus supplement;

•

currencies; or

•

commodities.

Each purchase contract will entitle the holder thereof to purchase or sell, and obligate us to sell or purchase, on specified dates, such securities, currencies or commodities at a specified purchase price, which may be based on a formula, all as set forth in the applicable prospectus supplement. We may, however, satisfy our obligations, if any, with respect to any purchase contract by delivering the cash value of such purchase contract or the cash value of the property otherwise deliverable or, in the case of purchase contracts on underlying currencies, by delivering the underlying currencies, as set forth in the applicable prospectus supplement. The applicable prospectus supplement will also specify the methods by which the holders may purchase or sell such securities, currencies or commodities and any acceleration, cancellation or termination provisions or other provisions relating to the settlement of a purchase contract.

The purchase contracts may require us to make periodic payments to the holders thereof or vice versa, which payments may be deferred to the extent set forth in the applicable prospectus supplement, and those payments may be unsecured or prefunded on some basis. The purchase contracts may require the holders thereof to secure their obligations in a specified manner to be described in the applicable prospectus supplement. Alternatively, purchase contracts may require holders to satisfy their obligations thereunder when the purchase contracts are issued. Our obligation to settle such pre-paid purchase contracts on the relevant settlement date may constitute indebtedness. Accordingly, pre-paid purchase contracts will be issued under the indenture.

DESCRIPTION OF UNITS

As specified in the applicable prospectus supplement, we may issue units consisting of one or more warrants, debt securities, shares of preferred stock, shares of common stock or any combination of such securities.

DESCRIPTION OF DEPOSITARY SHARES

The following description of depositary shares is only a summary and is qualified by any prospectus supplement, deposit agreement and depositary receipt used in connection with the issuance of each series of preferred stock issued through the use of depositary shares. Therefore, you should read carefully the more detailed description that would be contained in any prospectus supplement and form of deposit agreement and depositary receipt, copies of which would be incorporated by reference as exhibits to the registration statement of which this prospectus is a part.

We may offer fractional shares of preferred stock by issuing receipts for depositary shares. The shares of any class or series of preferred stock represented by depositary shares will be deposited with a bank or trust company (the “bank depositary”) and the holders will be issued a depositary receipt entitling them, in proportion to the fraction of a share the receipt represents, to all the rights and preferences of the preferred stock as may be fixed by the Board from time to time.

The bank depositary will function as the intermediary between the Company and the holders of the depositary receipts. Dividends and other distributions will be provided to the bank depositary for ultimate distribution to the holders. Redemption of the depositary shares and voting the underlying preferred stock will also be coordinated through the bank depositary. Holders will have the right to surrender their depositary receipts to the bank depositary and be entitled to receive whole shares of preferred stock that are represented by such receipts. Though the preferred stock will continue to have all of the rights and preferences of such preferred stock before such surrender, there may be no market opportunity to trade such stock and once withdrawn from the bank depositary, it may not be redeposited.

We will pay all transfer and other taxes and governmental charges that arise solely from the existence of the depositary arrangements. We will pay charges of the bank depositary in connection with the initial deposit of the applicable class or series of preferred stock and any exchange or redemption of such class or series of preferred stock. Holders of depositary shares will pay all other transfer and other taxes and governmental charges, and, in addition, such other charges as are expressly provided in the deposit agreement to be for their accounts.

FORMS OF SECURITIES

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

Global Securities

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

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

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

So long as the depositary, or its nominee, is the registered owner of a registered global security, that depositary or its nominee, as the case may be, will be considered the sole owner or holder of the securities represented by the registered global security for all purposes under the applicable indenture, warrant agreement, unit agreement or deposit agreement. Except as described below, owners of beneficial interests in a registered global security will not be entitled to have the securities represented by the registered global security registered in their names, will not receive or be entitled to receive physical delivery of the securities in definitive form and will not be considered the owners or holders of the securities under the applicable indenture, warrant agreement, unit agreement or deposit agreement. Accordingly, each person owning a beneficial interest in a registered global security must rely on the procedures of the depositary for that registered global security and, if that person is not a participant, on the procedures of the participant through which the person owns its interest, to exercise any rights of a holder under the applicable indenture, warrant agreement, unit agreement or deposit agreement. We understand that under existing industry practices, if we request any action of holders or if an owner of a

beneficial interest in a registered global security desires to give or take any action that a holder is entitled to give or take under the applicable indenture, warrant agreement, unit agreement or deposit agreement, the depositary for the registered global security would authorize the participants holding the relevant beneficial interests to give or take that action, and the participants would authorize beneficial owners owning through them to give or take that action or would otherwise act upon the instructions of beneficial owners holding through them.

Principal, premium, if any, and interest payments on debt securities, and any payments to holders with respect to warrants, units or depositary shares, represented by a registered global security registered in the name of a depositary or its nominee will be made to the depositary or its nominee, as the case may be, as the registered owner of the registered global security. None of Super Micro, the trustee, any warrant agent, unit agent, bank depositary for depositary shares or any other agent of Super Micro, agent of the trustee or agent of such warrant agent, unit agent or bank depositary for depositary shares will have any responsibility or liability for any aspect of the records relating to payments made on account of beneficial ownership interests in the registered global security or for maintaining, supervising or reviewing any records relating to those beneficial ownership interests.

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

If the depositary for any of these securities represented by a registered global security is at any time unwilling or unable to continue as depositary or ceases to be a clearing agency registered under the Exchange Act, and a successor depositary registered as a clearing agency under the Exchange Act is not appointed by us within 90 days, we will issue securities in definitive form in exchange for the registered global security that had been held by the depositary. Any securities issued in definitive form in exchange for a registered global security will be registered in the name or names that the depositary gives to the relevant trustee, warrant agent, unit agent, bank depositary for depositary shares or other relevant agent of ours or theirs. It is expected that the depositary’s instructions will be based upon directions received by the depositary from participants with respect to ownership of beneficial interests in the registered global security that had been held by the depositary. In addition, we may at any time determine that the securities of any series shall no longer be represented by a global security and will issue securities in definitive form in exchange for such global security pursuant to the procedure described above.

PLAN OF DISTRIBUTION

We or selling security holders may sell the securities described in this prospectus in the following manner or any manner specified in a prospectus supplement:

•

directly to purchasers, through a specific bidding or auction process or otherwise;

•

through agents;

•

to or through underwriters;

•

through broker-dealers (acting as agent or principal); and

•

through a combination of any of the foregoing methods of sale.

If any securities are sold pursuant to this prospectus by any persons other than us, we will, in a prospectus supplement, name the selling security holders, indicate the nature of any relationship such holders have had to us or any of our affiliates during the three years preceding such offering, state the amount of securities of the class owned by such security holder prior to the offering and the amount to be offered for the security holder’s account, and state the amount and (if one percent or more) the percentage of the class to be owned by such security holder after completion of the offering.

We or any selling security holder may directly solicit offers to purchase securities, or agents may be designated to solicit such offers. We will, in the prospectus supplement relating to such offering, name any agent that could be viewed as an underwriter under the Securities Act of 1933, as amended (the “Securities Act”), and describe any commissions that we or any selling security holder must pay. Any such agent will be acting on a best efforts basis for the period of its appointment or, if indicated in the applicable prospectus supplement, on a firm commitment basis. Agents, dealers and underwriters may be customers of, engage in transactions with, or perform services for us in the ordinary course of business.

If any underwriters or agents are utilized in the sale of the securities in respect of which this prospectus is delivered, we and, if applicable, any selling security holder will enter into an underwriting agreement or other agreement with them at the time of sale to them, and we will set forth in the prospectus supplement relating to such offering the names of the underwriters or agents and the terms of the related agreement with them.

If a dealer is utilized in the sale of the securities in respect of which the prospectus is delivered, we will sell such securities to the dealer, as principal. The dealer may then resell such securities to the public at varying prices to be determined by such dealer at the time of resale.

Remarketing firms, agents, underwriters and dealers may be entitled under agreements which they may enter into with us to indemnification by us and by any selling security holder against certain civil liabilities, including liabilities under the Securities Act, and may be customers of, engage in transactions with or perform services for us in the ordinary course of business.

In order to facilitate the offering of the securities, any underwriters may engage in transactions that stabilize, maintain or otherwise affect the price of the securities or any other securities the prices of which may be used to determine payments on such securities. Specifically, any underwriters may overallot in connection with the offering, creating a short position for their own accounts. In addition, to cover overallotments or to stabilize the price of the securities or of any such other securities, the underwriters may bid for, and purchase, the securities or any such other securities in the open market. Finally, in any offering of the securities through a syndicate of underwriters, the underwriting syndicate may reclaim selling concessions allowed to an underwriter or a dealer for distributing the securities in the offering if the syndicate repurchases previously distributed securities in transactions to cover syndicate short positions, in stabilization transactions or otherwise. Any of these activities may stabilize or maintain the market price of the securities above independent market levels. Any such underwriters are not required to engage in these activities and may end any of these activities at any time.

Any underwriter, agent or dealer utilized in the initial offering of securities will not confirm sales to accounts over which it exercises discretionary authority without the prior specific written approval of its customer.

VALIDITY OF SECURITIES

In connection with particular offerings of the securities in the future, and if stated in the applicable prospectus supplements, the validity of those securities will be passed on for us by Freshfields US LLP, and for any underwriters or agents, by counsel named in the applicable prospectus supplement.
