Riot Platforms, Inc.

Item 1.01 – Entry into a Material Definitive Agreement. On August 10, 2026, Riot DC Logistics, LLC (the “Borrower”), a wholly owned subsidiary of Riot Platforms, Inc. (the “Company”), entered into a credit agreement (the “Credit Agreement”) by and among the Borrower, the several banks and other financial institutions from time to time party thereto as lenders (the “Lenders”), and Morgan Stanley Senior Funding, Inc., as administrative agent (in such capacity, the “Administrative Agent”). Pursuant to the terms of the Credit Agreement, the Lenders agreed to provide the Borrower with a senior secured delayed-draw term loan facility in an aggregate principal amount of up to $573.0 million (the “Facility”), which is available for borrowing during the Availability Period (as defined in the Credit Agreement), commencing on August 10, 2026. The proceeds of the Facility are intended to fund the purchase of long-lead equipment and related project equipment, and certain other expenses associated with the Company’s 191 critical IT MW data center project at its Rockdale Facility. Loans under the Facility bear interest, at the Borrower’s election, at a rate per annum equal to (i) the Adjusted Term SOFR rate plus an applicable margin of 2.75%, or (ii) the Base Rate (as defined in the Credit Agreement) plus an applicable margin of 1.75%, in each case as more fully described in the Credit Agreement. Loans under the Facility mature on December 31, 2026, subject to the terms and conditions of the Credit Agreement. The Borrower is also obligated to pay customary agency fees, an undrawn fee, and other customary fees for a credit facility of this size and type. The Borrower’s obligations under the Credit Agreement are guaranteed by each subsidiary of the Borrower and its affiliate, RPI AUS01-0H DC LLC, a Delaware limited liability company (together with the Borrower, the “Credit Parties”), pursuant to a guaranty dated as of the closing date. The Facility is secured by a lien on substantially all of the assets of the Credit Parties, pursuant to a Pledge and Security Agreement dated as of the closing date. The Credit Agreement provides that there shall be no recourse against the Company or any other direct or indirect parent of the Borrower, or their respective affiliates, other than the Credit Parties, for any liability arising in connection with any breach or default under the Credit Agreement, and that the Administrative Agent and the Lenders must look solely to the Credit Parties and the collateral securing the Facility to satisfy the obligations thereunder, subject to certain customary exceptions (including for fraud, willful misrepresentation or misappropriation of collateral proceeds). The Credit Agreement contains customary representations, warranties, covenants, and events of default for a secured term loan facility of this type, including covenant limitations on indebtedness, liens, restricted payments, investments, transactions with affiliates and changes in the nature of the Borrower’s business. The foregoing description of the Credit Agreement is a summary, does not purport to be complete, and is qualified in its entirety by reference to the full text of the Credit Agreement, a copy of which will be filed as an exhibit to the Company’s Quarterly Report on Form 10-Q for the fiscal quarter ending September 30, 2026.
