Super Micro Computer, Inc.

Common Stock

We are offering $1,250,000,000 of our common stock, par value $0.001 per share ("common stock"), consisting of       shares of common stock. Our common stock is listed on The Nasdaq Global Select Market under the symbol "SMCI." On June 9, 2026, the closing sale price of our common stock was $40.64.

Concurrently with this offering and pursuant to a separate prospectus supplement, we are making a public offering (the "Depositary Shares Offering") of 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 ("Mandatory Convertible Preferred Stock"). We expect to grant the underwriters of the Depositary Shares Offering a 30-day option to purchase up to an additional 11,250,000 Depositary Shares, solely to cover over-allotments. 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 $2,000,000,000 of shares of our common stock in "at-the-market" transactions from time to time (the "ATM Program" and, together with the Depositary Shares Offering, the "Concurrent Financing Transactions"). The closing of this offering is not conditioned upon the closing of the Depositary Shares Offering or entry into the ATM Program. Neither the closing of the Depositary Shares Offering nor entry into the ATM Program is conditioned upon the closing of this offering. We cannot assure you that the Depositary Shares 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 Depositary Shares or the Mandatory Convertible Preferred Stock being offered in the Depositary Shares 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,
