Risks

• Preliminary, unaudited financial results are subject to the completion of year-end closing procedures and audit, meaning final results could differ.
• Investing in the company's securities involves a high degree of risk, as detailed in the "Risk Factors" section of the most recent annual report on Form 10-K.
• Actual results and outcomes could differ materially from forward-looking statements due to various factors, including those outlined in SEC filings.
• The decline in Bitcoin price significantly impacted net income and Adjusted EBITDA, highlighting exposure to cryptocurrency market volatility.
• Higher global network difficulty outpaced hashrate growth, reducing Bitcoin mined per unit of energy and increasing costs.
• Increased power costs due to seasonal factors and adverse weather events can negatively impact profitability.
• The MPLX initiative for integrated power and data campuses is a longer-term project requiring significant capital investment, and its scope has evolved, indicating potential uncertainties or changes.
• The company's strategy to monetize Bitcoin holdings opportunistically in 2026 to fund operations is subject to market conditions and capital allocation priorities, introducing market risk.

Future Outlook

MARA views 2026 as an inflection point, with infrastructure in place and strategic partnerships advancing assets toward hyperscale tenancy and enterprise AI capabilities. The company expects to continue monetizing Bitcoin opportunistically in 2026 to enhance financial flexibility and fund capital projects, while focusing on operational delivery, disciplined capital allocation, and directing energy to its highest-value use. The joint platform with Starwood is expected to support over 1 gigawatt of IT capacity initially, with a roadmap to extend beyond 2.5 gigawatts over time.

Management Comments

• "This quarter, we are accelerating MARAs expansion into AI and high-performance compute with the announcement of our strategic joint venture with Starwood Digital Ventures (Starwood)."
• "This partnership marks an important step forward in the evolution of our platform and reflects the intentional transformation of our business from a pure-play Bitcoin miner into an energy and digital infrastructure company."
• "We believe it is critical to partner with best-in-class operators."
• "Bitcoin mining remains an integral part of this model, continuing to serve as a flexible, always-on workload that monetizes power while higher-value compute capacity is developed and deployed."
• "Looking ahead, we believe the next decade of digital infrastructure will be shaped less by compute availability and more by energy constraints."
• "We believe MARA is strategically advantaged in this environment."
• "2025 was a year of deliberate investment and foundation building for our next phase of growth."
• "While below our 75 EH/s target, this outcome reflects deliberate capital discipline. We chose not to deploy capital into new builds that failed to meet our return thresholds, instead focusing on optimization."
• "Our long-term conviction in the asset class remains unchanged."
• "We view 2026 as an inflection point."

Industry Context

StockSavvy.ai notes that MARA's strategic pivot towards AI and high-performance compute infrastructure, alongside its core Bitcoin mining operations, aligns with a broader industry trend where energy-intensive computing companies are diversifying their revenue streams and leveraging existing power infrastructure for higher-value workloads. The emphasis on power ownership and modular, scalable infrastructure positions MARA to capitalize on the increasing demand for AI compute, which is currently constrained more by energy availability than by compute capacity itself. This move could differentiate MARA from pure-play Bitcoin miners, who face increasing network difficulty and volatile Bitcoin prices, by tapping into the rapidly growing data center market for enterprise and hyperscale clients.

Comparison to Industry Standards

• The filing does not provide specific comparable companies, projects, or results for direct industry benchmarking.
• MARA's strategic shift to AI and HPC infrastructure, leveraging existing power-rich sites, positions it to compete with traditional data center developers and cloud providers in the high-demand segments of the data center market.
• The planned 1 GW initial IT capacity with a roadmap to over 2.5 GW through the Starwood joint venture indicates an ambition to operate at a scale comparable to significant players in the data center and AI infrastructure space.

Stakeholder Impact

• Shareholders: Significant net losses and Adjusted EBITDA losses in Q4 and FY 2025 could negatively impact shareholder value in the short term. However, the strategic shift to AI/HPC and infrastructure control aims to create long-term value and diversify revenue streams, potentially benefiting shareholders in the future.
• Employees: Scaling operations and headcount growth, as indicated by increased G&A expenses, suggests potential for job creation and stability within the expanding digital infrastructure segments.
• Customers (future AI/HPC): The joint venture with Starwood and investment in Exaion aim to meet growing demand from enterprise, hyperscale, and AI customers, providing new services and infrastructure.
• Creditors: The company's substantial Bitcoin holdings and combined cash and BTC of $5.3 billion provide a strong liquid asset base, which could be viewed positively by creditors despite the recent financial losses. The shift from ATM usage to Bitcoin monetization for funding operations also impacts liquidity management.
• Suppliers: Expansion of mining sites, deployment of new miners, and development of new data centers will likely increase demand for equipment and services from suppliers.

Next Steps

• Complete year-end closing procedures and audit for final results to be provided in the Annual Report on Form 10-K for the year ended December 31, 2025.
• Develop, finance, and operate next-generation digital infrastructure through the joint venture with Starwood Digital Ventures.
• MARA has the option to invest up to 50 percent in joint venture projects.
• Continue mining operations where capacity is available at attractive power costs.
• Position the platform to support a broad range of AI deployment requirements, including large-scale cloud, private, enterprise, and sovereign deployments.
• Selectively convert capacity to higher-value workloads, including AI inference and high-performance compute, deploying capital only where returns justify investment.
• Advance discussions with major energy companies in France regarding global opportunities, including in Brazil, and domestic energy producers in Saudi Arabia.
• Continue to advance discussions with MPLX regarding the development of integrated power and data campuses in West Texas, evaluating a transaction structure.
• Monetize Bitcoin opportunistically in 2026 to enhance financial flexibility, including providing liquidity or funding capital projects and other initiatives.
• Execute on strategy in 2026, leveraging infrastructure, upgrades, Starwood partnership, and Exaion capabilities.

Key Dates

Recommendation

The filing presents a complex picture. While the significant net loss and negative Adjusted EBITDA for Q4 and FY 2025 are concerning, primarily driven by Bitcoin price volatility, the strategic pivot towards AI and high-performance compute infrastructure through key partnerships and acquisitions is a strong long-term positive. The company is actively transforming its business model to diversify revenue and leverage its energy assets for higher-value workloads. However, the immediate financial performance and the inherent volatility of Bitcoin, which remains a core asset, warrant caution. A 'hold' recommendation allows investors to observe the execution of this strategic transformation and its impact on future financial results, without reacting solely to the short-term negative earnings.
