Future Outlook

MARA is on track to reach its year-end target of 75 exahash (EH/s). The company expects costs on a unit basis to continue to decline as it transitions to a more owned and operated model, phases out third-party hosted contracts, and brings low-cost sites like wind farms online. It aims to generate more than 50% of revenues from international markets by 2028. The company is exploring ways for its infrastructure to support hybrid applications, including AI inference and High-Performance Computing (HPC), and is laying the foundation for a new era of AI infrastructure by deploying custom miners and pursuing partnerships for sovereign, energy-aware compute.

Management Comments

• We are evolving into a digital energy company. We are on a mission to advance the world's energy systems by providing flexible demand for underutilized power.
• Currently, our workloads are anchored in bitcoin mining, which we believe is the most scalable and adaptable digital energy technology in the world today, transforming how energy is produced, delivered, and consumed. But the opportunity extends far beyond mining on its own.
• We are now exploring ways for our infrastructure to support hybrid applications, including AI inference and HPC. This unlocks entirely new ways to orchestrate power and maximize the value of every electron.
• MARA's bitcoin holdings surpassed 50,000 BTC, solidifying our position as the second-largest corporate public holder of bitcoin – a treasury earned through infrastructure, execution, and scale.
• We are a bitcoin miner at our core, focused on building a resilient and sustainable business. We accomplish this by using mining not just to acquire bitcoin but also to optimize energy systems, monetize stranded assets, and advance our position in digital energy infrastructure.
• We actively deploy portions of our holdings to enhance returns and strengthen our long-term capital position.
• As AI demands more power, more uptime, and more scale, MARA is positioned to lead.
• Just as countries require their own banking systems, energy grids, and public health infrastructure, they now require something new: sovereign, deployable AI they can trust.
• We are confident in our ability to execute.
• We don't just hold bitcoin, we put it to work.

Industry Context

The filing positions MARA at the intersection of the rapidly growing energy and compute industries. It highlights the increasing global demand for compute, particularly for AI inference, and the challenge of inflexible load profiles for traditional data centers. MARA aims to address this by providing flexible demand for underutilized power, evolving into a 'digital energy company.' The company contrasts its approach with 'bitcoin treasury companies,' emphasizing its operational excellence in mining and its strategic shift towards vertically integrated, low-cost energy infrastructure. It also notes the shift in AI processing from training to inferencing and the need for sovereign, energy-aware edge AI infrastructure, where MARA sees a leadership opportunity.

Comparison to Industry Standards

• Purchased energy costs per bitcoin ($33,735) and cost per petahash per day ($28.7) remain among the lowest in the sector.
• Bitcoin treasury position as the second-largest corporate public holder of bitcoin, with the majority mined rather than purchased, differentiating it from other bitcoin treasury companies.
• Leadership in bitcoin mining is underpinned by BTC holdings more than twice the size of the next largest miner.
• Facilities are engineered for 100+ megawatt workloads and can curtail within minutes, contrasting with many data center operators managing tens of megawatts.
• References a Duke study indicating 76 to 126 gigawatts of capacity available for data centers if they can curtail just 0.5% to 1.0% of the time, highlighting MARA's flexible load profile advantage.
• References Gartner research projecting a 42% CAGR for inference servers through 2028, compared to 24% for training servers, aligning MARA's strategic focus with high-growth AI segments.
• Mentions Professor Aswath Damodaran of NYU's Stern School of Business regarding companies diverting corporate cash into bitcoin, reinforcing MARA's operational-first approach to bitcoin acquisition.
