Hyperscale Data, Inc., a Delaware corporation (the “Company”), is offering to purchase for cash up to an aggregate of 23,809,523 shares of its Class A common stock, $0.001 par value per share (the “shares”), for an aggregate purchase price of up to $5 million, at a purchase price of $0.21 per share, net to the seller in cash, less any applicable withholding taxes and without interest, upon the terms and subject to the conditions set forth in the Offer to Purchase dated May 26, 2026 (the “Offer to Purchase”) and the related Letter of Transmittal (which, together with any supplements or amendments thereto, collectively constitute the “Offer”). Please furnish copies of the enclosed materials to those of your clients for whom you hold shares registered in your name or in the name of your nominee. Capitalized terms used herein without definition have the meanings set forth in the Offer to Purchase.

Only shares validly tendered and not properly withdrawn at or prior to the Expiration Time will be eligible for purchase in the Offer. Due to the proration offer provisions described in the Offer to Purchase, all of the shares tendered may not be purchased if more than 23,809,523 shares are properly tendered and not properly withdrawn at or prior to the Expiration Time. The Company expressly reserves the right, in its sole discretion, to change the purchase price and to increase or decrease the aggregate value of shares sought in the Offer or otherwise amend the Offer, subject to applicable law. In accordance with the rules of the U.S. Securities and Exchange Commission, the Company may purchase in the Offer up to an additional 2% of its outstanding shares without amending or extending the Offer.

The Company will purchase only those shares properly tendered and not properly withdrawn upon the terms and conditions of the Offer. All shares accepted for payment will be paid promptly after the Expiration Time, net to the seller in cash, less any applicable withholding taxes and without interest. If the Offer is fully subscribed, the Company would purchase 23,809,523 shares pursuant to the Offer, which would represent approximately 5.1% of the outstanding shares as of May 15, 2026.

Shares not purchased in the Offer will be returned at the Company’s expense promptly following the expiration of the Offer. See Section 3 of the Offer to Purchase. The Company expressly reserves the right, in its sole discretion, to change the per share purchase price and to increase or decrease the aggregate value of shares sought in the Offer or otherwise amend the Offer, subject to applicable law. See Sections 1 and 14 of the Offer to Purchase.

If the conditions of the Offer have been satisfied or waived and more than 23,809,523 shares (or such greater number of shares as the Company may elect to purchase, subject to applicable law) have been properly tendered and not properly withdrawn at or prior to the Expiration Time, the Company will purchase shares from all holders who properly tender shares and do not properly withdraw them, on a pro rata basis.

Because of the proration provisions described above, the Company may not purchase all of the shares that you tender. See Sections 1, and 3 of the Offer to Purchase.
