• MARA has waived the right to seek special, consequential, punitive, speculative, or indirect damages from Starwood for breaches of the agreement, except in cases of actual fraud.

Risks

• Forward-looking statements in the filing involve many risks and uncertainties that could cause MARA's actual results to differ materially from those expressed or implied.
• Uncertainties related to general market conditions could impact the success and profitability of the digital infrastructure projects.
• Other factors discussed in the Risk Factors section of MARA's Annual Report on Form 10-K and other SEC filings could materially affect MARA's business.
• A 'Non-Funding Event' could occur if MARA defaults on its obligation to fund Approved Pursuit Costs, potentially leading to loss of rights or other remedies for Starwood.
• Starwood may determine that it is not commercially feasible to develop a data center on a target property, leading to the termination of the exclusivity period for that property.
• MARA faces the risk of being required to sell its rights to powered land to Starwood if it does not elect to proceed with a joint venture after Starwood procures an executable hyperscaler lease.
• Existing legal proceedings, such as the Granbury Litigation, could impact the development or operation of specific target properties.

Future Outlook

The filing outlines MARA and Starwood's planned joint development of digital infrastructure projects, with an expected near-term IT capacity of approximately 1 GW and a pathway to over 2.5 GW. These facilities are anticipated to offer scalability and performance, with the ability to shift between hyperscale and AI workloads and Bitcoin mining. The proposed transaction is expected to benefit MARA by accelerating its expansion into high-performance computing and advancing its integrated, energy-backed digital infrastructure strategy.

Management Comments

• Fred Thiel, MARA's Chairman and CEO, stated: "Our partnership with Starwood will allow us to turn that power certainty into capacity certainty, so customers can run diverse workloads close to their data and users. This joint venture structure also gives us a more capital-efficient way to accelerate the buildout of digital infrastructure across our portfolio. Together, this partnership will accelerate our expansion into high-performance computing and advance our strategy to build an integrated, energy-backed digital infrastructure platform."
• Barry Sternlicht, Starwood Capital Chairman and CEO, commented: "Data centers are the infrastructure responsible for driving the modern economy, and our partnership with MARA expands our opportunities to continue investing in this sector."
• Anthony Balestrieri, Managing Director and CEO for Starwood Digital Ventures, noted: "MARA's operating sites and energy expertise help advance SDV's operating philosophy in new and growing markets."

Industry Context

StockSavvy.ai notes that this partnership strategically positions MARA to capitalize on the surging demand for high-performance computing, particularly for AI and hyperscale applications, by leveraging its existing energy infrastructure. This move diversifies MARA's revenue streams beyond pure Bitcoin mining, aligning with a broader industry trend of integrating digital asset infrastructure with general-purpose data center capabilities to optimize asset utilization and mitigate crypto market volatility. The collaboration with a major real estate investment firm like Starwood also signals a maturation of the digital infrastructure sector, attracting institutional capital and expertise.

Comparison to Industry Standards

• The target of 1 GW near-term IT capacity with a pathway to over 2.5 GW is substantial, comparable to major global data center operators such as Digital Realty, which operates over 4 GW globally, or Equinix, with over 2.5 GW across its portfolio.
• The strategy of integrating Bitcoin mining with hyperscale/AI compute capabilities mirrors approaches seen in companies like Riot Platforms, which also explores flexible power usage for different compute demands, though MARA's partnership with Starwood brings a significant institutional real estate development partner to the table.
• Starwood Capital Group's existing data center development portfolio, including Echelon Data Centers and investments with Iberdrola and Telstra Group, demonstrates its established presence and expertise, providing a strong benchmark for the partnership's potential execution capabilities.
