Trade Date		June 11, 2026 (“T”).

Expected Settlement Date for the Common Stock Offering		June 12, 2026 (T+1).

Expected Settlement Date for the Depositary Shares Offering		June 15, 2026 (T+2), 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, 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.

Use of Proceeds		The Issuer expects the net proceeds from (i) the Common Stock Offering to be approximately $1.22 billion (or approximately $1.40 billion if the underwriters of the Common Stock Offering exercise in full their option to purchase additional common stock) and (ii) the Depositary Shares Offering to be approximately $3.68 billion (or approximately $4.23 billion if the underwriters of the Depositary Shares Offering exercise in full their over-allotment option to purchase additional Depositary Shares), in each case, after deducting the applicable underwriting discounts and the Issuer’s estimated offering expenses totaling approximately $2.58 million. The Issuer intends to use the net proceeds from the Common Stock Offering and the Depositary Shares Offering to fund the purchase of components to satisfy the approximately $39 billion of orders that the Issuer has received in recent weeks for its advanced AI servers, including its Data Center Building Block Solutions, from more than 20 customers, that the Issuer plans to fulfill in future quarters. The Issuer may also use a portion of the net proceeds from Common Stock Offering and the Depositary Shares Offering for other general corporate purposes, which may include repayment of debt, additions to working capital and capital expenditures..

At settlement of the Depositary Shares Offering, the Issuer will issue 3,750,000 shares of Mandatory Convertible Preferred Stock, subject to the underwriters’ over-allotment option.

Over-allotment Option for Underwriters to Purchase Additional Depositary Shares		11,250,000 additional Depositary Shares (corresponding to 562,500 additional shares of the Mandatory Convertible Preferred Stock), solely to cover over-allotments.

Dividends		7.00% of the liquidation preference of $1,000 per share of the Mandatory Convertible Preferred Stock per annum. Dividends will accumulate from the Settlement Date for the Depositary Shares Offering, 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 the Issuer is legally permitted to pay dividends and its board of directors, or an authorized committee thereof, declares a dividend payable with respect to the Mandatory Convertible Preferred Stock, the Issuer will pay such dividends in cash or, subject to certain limitations, by delivery of shares of Common Stock or through any combination of cash and shares of Common Stock, as determined by the Issuer’s board of directors in its sole discretion, on each Dividend Payment Date; provided that any unpaid dividends will continue to accumulate.

		The expected dividend payable on the first Dividend Payment Date is approximately $14.78 per share of Mandatory Convertible Preferred Stock (equivalent to approximately $0.74 per Depositary Share). Each subsequent dividend is expected to be $17.50 per share of Mandatory Convertible Preferred Stock (equivalent to $0.875 per Depositary Share).

Initial Price		Equal to $1,000, divided by the Maximum Conversion Rate, rounded to the nearest $0.0001, which initially is $27.4997.

Threshold Appreciation Price		Equal to $1,000, divided by the Minimum Conversion Rate, rounded to the nearest $0.0001, which initially is $32.9989 and represents a premium of approximately 20.0% over the Initial Price.

Conversion Rate per Share of Mandatory Convertible Preferred Stock		The conversion rate for each share of Mandatory Convertible Preferred Stock will not be more than 36.3640 shares of Common Stock and not less than 30.3040 shares of Common Stock (respectively, the “Maximum Conversion Rate” and “Minimum Conversion Rate”), depending on the applicable market value (as defined in the Depositary Shares Preliminary Prospectus Supplement) of the Common Stock, as described below and subject to certain anti-dilution adjustments.

		The following table illustrates the conversion rate per share of the Mandatory Convertible Preferred Stock, subject to certain anti-dilution adjustments described in the Depositary Shares Preliminary Prospectus Supplement, based on the applicable market value of the Common Stock:

Optional Conversion		Other than during a fundamental change conversion period (as defined in the Depositary Shares Preliminary Prospectus Supplement), at any time prior to June 1, 2029, a holder of Mandatory Convertible Preferred Stock may elect to convert such holder’s shares of Mandatory Convertible Preferred Stock, in whole or in part, at the Minimum Conversion Rate of 30.3040 shares of Common Stock per share of Mandatory Convertible Preferred Stock (equivalent to 1.5152 shares of Common Stock per Depositary Share), subject to adjustment as described in the Depositary Shares Preliminary Prospectus Supplement. Because each Depositary Share represents a 1/20th fractional interest in a share of Mandatory Convertible Preferred Stock, a holder of Depositary Shares may convert its Depositary Shares only in lots of 20 Depositary Shares.

Fundamental Change		If a fundamental change (as defined in the Depositary Shares Preliminary Prospectus Supplement) 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

•

if the stock price is in excess of $70.00 per share (subject to adjustment in the same manner as the stock prices in the column headings of the table above as described in the Depositary Shares Preliminary Prospectus Supplement), then the fundamental change conversion rate per share of Mandatory Convertible Preferred Stock will be the Minimum Conversion Rate; and

•

if the stock price is less than $11.00 per share (subject to adjustment in the same manner as the stock prices in the column headings of the table above as described in the Depositary Shares Preliminary Prospectus Supplement), then the fundamental change conversion rate per share of Mandatory Convertible Preferred Stock will be the Maximum Conversion Rate.

The exact stock price and effective date may not be set forth on 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;

•

if the stock price is in excess of $70.00 per share (subject to adjustment in the same manner as the stock prices in the column headings of the table above as described in the Depositary Shares Preliminary Prospectus Supplement), 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 $11.00 per share (subject to adjustment in the same manner as the stock prices in the column headings of the table above as described in the Depositary Shares Preliminary Prospectus Supplement), then the fundamental change conversion rate per Depositary Share will be the Maximum Conversion Rate, divided by 20.

Because each Depositary Share represents a 1/20th fractional interest in a share of Mandatory Convertible Preferred Stock, a holder of Depositary Shares may convert its Depositary Shares upon the occurrence of a fundamental change only in lots of 20 Depositary Shares.


Discount Rate for Purposes of Fundamental Change Dividend Make-Whole Amount		The discount rate for purposes of determining the fundamental change dividend make-whole amount (as defined in the Depositary Shares Preliminary Prospectus Supplement) is 8.90% per annum.
