Item 1.01. Entry Into a Material Definitive Agreement.

On February 26, 2026, MARA USA Corporation (the “Company”), a wholly owned subsidiary of MARA Holdings, Inc. (“MARA”), entered into a Strategic Agreement (the “Strategic Agreement”) with Starwood Capital Group Global III, L.P. (“Starwood”) pursuant to which the Company and Starwood have agreed to, amongst other things, develop, lease and market a specified list of the Company’s existing bitcoin mining data centers (i.e., all of its United States properties other than those held in existing third-party joint ventures). Starwood is required to perform pre-development services with respect to the properties, including due diligence, obtaining governmental permits and approvals and securing power arrangements and procuring a hyperscaler tenant. Those services will be performed at the Company’s cost, subject to certain caps and subject to Starwood’s right to continue pre-development activities at its own expense if the caps are reached.

Once one or more specified triggers have been achieved (e.g., the procurement of an executable lease with a hyperscaler tenant that satisfies certain criteria), each of the Company and Starwood will have the right to decide whether to proceed with the development of a data center at the property. The decision is also required to be made 24 months after closing (subject to extension by 12 months if Starwood is in active bona fide negotiations with at least one hyperscaler tenant), even if no specified trigger has been achieved. Starwood may also send a notice to the Company at any time if it determines that it is not commercially feasible to develop a data center at the property.

If both the Company and Starwood decide to proceed with a given property, the property will be contributed to a newly-formed joint venture (each, a “Joint Venture”) between the Company and Starwood. The Company will elect to have a percentage interest between 10% and 50% in each Joint Venture. Starwood will be the managing member of each Joint Venture and will manage the day-to-day operations of the development, subject to the Company having approval rights over certain major decisions (with the list of such decisions to vary depending on what percentage interest the Company elects). Starwood will have the right to make capital calls to fund certain costs and expenses relating to the development and operation of each data center.

If Starwood elects to proceed but the Company does not after Starwood has procured an executable lease with a hyperscaler tenant that satisfies certain criteria, the Company will be required to sell its rights to the powered land at the asset to Starwood.

Regardless of whether a property is contributed to a Joint Venture or sold to Starwood, the Company will either (1) continue to have its existing bitcoin mining rights at the property pursuant to a rent-free lease and will continue to own the bitcoin miners and other personal property infrastructure located at the property or (2) be compensated to relocate from such property.

For each Joint Venture, after a specified lock-out period, Starwood will have the right to force the sale of the applicable property, subject to a right of first offer in favor of the Company. The Company will also have the right to force a sale after the specified lock-out period, subject to a right of first offer in favor of Starwood.

The foregoing description of the Strategic Agreement does not purport to be complete and is qualified in its entirety by reference to the full text of such agreement, which is filed as Exhibit 10.1 to this Current Report on Form 8-K.

Item 7.01. Regulation FD Disclosure.

On February 26, 2026, the Company issued a joint press release with Starwood announcing its entry into the Strategic Agreement. A copy of the press release is furnished as Exhibit 99.1 to this Current Report on Form 8-K and is incorporated herein by reference.

The information contained in this Item 7.01, including Exhibit 99.1 hereto, shall not be deemed “filed” for purposes of Section 18 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), nor shall it be deemed incorporated by reference in any filing under the Securities Act of 1933, as amended, or the Exchange Act, except as expressly set forth by specific reference in such filing.
