Risks

• Uncertainties related to market conditions.
• Ability to mine bitcoin profitably.
• Ability to attract additional customers to lease HPC data centers.
• Ability to perform under existing data center lease agreements.
• Changes in applicable laws, regulations, and/or permits affecting operations.
• Ability to implement business objectives, including bitcoin mining and HPC data center development, and to timely and cost-effectively execute related projects.
• Failure to obtain adequate financing on a timely basis and/or on acceptable terms for expansion or existing operations.
• Adverse geopolitical or economic conditions, including high inflationary environments, new tariffs, and more restrictive trade regulations.
• Potential for cybercrime, money-laundering, malware infections, phishing, and/or loss and interference due to equipment malfunction, physical disaster, data security breach, computer malfunction, or sabotage.
• Availability and cost of power, as well as electrical infrastructure equipment necessary to maintain and grow the business.
• Operational and financial risks associated with the expansion of the Lake Mariner data center.

Future Outlook

TeraWulf is executing an upwardly revised growth strategy, targeting an additional 250 MW to 500 MW of contracted critical IT load per year, building on the over 510 MW already secured in the last 10 months.

Key Dates

Recommendation

The filing details a highly strategic and financially robust joint venture with Fluidstack, significantly backed by Google, securing $9.5 billion in long-term contracted revenue. This validates TeraWulf's business model, provides substantial revenue visibility, and materially de-risks future growth. Coupled with strong preliminary Q3 2025 financial results showing significant year-over-year growth and an aggressive, achievable growth strategy for HPC capacity, the company is exceptionally well-positioned in the high-demand AI infrastructure market. The exclusive rights for future expansion further enhance its long-term potential, making it a compelling investment opportunity.
