Negatives

• Purchased energy cost per Bitcoin increased to $39,235 in Q3 2025 from $32,433 in Q3 2024, primarily due to increased network difficulty.
• Operating and maintenance costs increased by $16.9 million to $26.3 million, driven by higher shipping, warehouse fees, and labor costs.

• Depreciation and amortization increased by $65.5 million to $167.3 million due to the deployment of additional mining rigs.

Risks

• Investing in the company's securities involves a high degree of risk, as detailed in the most recent annual report on Form 10-K and other periodic reports.
• Bitcoin price volatility is expected to have a greater impact on earnings as Bitcoin holdings grow; a $10,000 change in BTC price could swing earnings by nearly $530 million.
• Uncertainty in global trade dynamics and signs of tech-heavy equity markets peaking suggest a period of Bitcoin consolidation with bouts of volatility.
• The company may incur losses on short-term Bitcoin trades or positions as part of its digital asset management strategy.
• Forward-looking statements involve many risks and uncertainties that could cause actual results to differ materially from expectations.

Future Outlook

MARA plans to evolve into a vertically integrated digital infrastructure operator combining energy generation, Bitcoin mining, and AI compute under one scalable platform over the next three to five years. The company aims to reach 75 EH/s of energized hashrate by year-end 2025 and expects to derive 50% of its revenue from international operations by 2028. Future plans include evaluating each megawatt's return profile across Bitcoin mining, grid participation, and AI workloads, with a focus on maximizing profit per megawatt hour. The pending acquisition of Exaion is expected to close shortly after regulatory approvals in Q4, and the collaboration with MPLX will develop integrated power generation and data center campuses in West Texas, with initial capacity of ~400 MW and potential expansion up to 1.5 GW.

Management Comments

• "We believe electrons are the new oil, and energy is becoming the defining resource of the digital economy."
• "MARA's leadership in Bitcoin mining places us at the center of this structural shift. We operate a global fleet of energy-to-value infrastructure, transforming power directly into Bitcoin held on our balance sheet."
• "By owning low-cost, reliable power, we believe MARA is positioned to convert that power into scalable intelligence at an efficient marginal cost per token."
• "Our mission remains the same: to harness large volumes of power and channel them toward their most productive use cases, whether that be Bitcoin mining or AI/HPC."
• "Our North Star is directing power to where it delivers the greatest long-term value and maximizes profit per megawatt hour."
• "The market has yet to fully value our diversification into owned energy and modular compute, and we believe continued execution across these platforms will close that gap over time."

Industry Context

The filing highlights the institutionalization of Bitcoin, with global financial leaders integrating it into traditional frameworks, recognizing it as 'digital energy.' It also emphasizes the convergence of energy and compute, positioning energy as the foundational input for both Bitcoin mining and artificial intelligence. The company notes the exponential growth in AI power demand and the shift in compute economics from cost per chip to cost per token, making energy efficiency a defining factor. A new trend of repatriation from public clouds to private infrastructure for AI workloads, driven by control, predictability, and trust, is also identified.

Comparison to Industry Standards

• MARA's electricity cost per coin is stated to be among the lowest in the sector due to its pivot from an asset-light to a vertically integrated model.
• The company identifies itself as the second largest corporate holder of Bitcoin globally, indicating a significant position in the digital asset space.
• Gartner reports a 48% increase in private cloud inquiries over the past year, supporting MARA's strategic move into private cloud and AI/HPC solutions.
• Gartner forecasts that by 2028, over half of multinational enterprises will have established formal digital sovereignty strategies, aligning with MARA's focus on secure, localized AI infrastructure through Exaion.
